Opis:
Pemphigus is a skin disease that can cause a serious damage to human skin. Pemphigus can result in other issues including painful patches and infected blisters, which can result in sepsis, weight loss, and starvation, all of which can be life-threatening, tooth decay and gum disease. Early prediction of Pemphigus may save us from fatal disease. Machine learning has the potential to offer a highly efficient approach for decision-making and precise forecasting. The healthcare sector is experiencing remarkable advancements through the utilization of machine learning techniques. Therefore, to identify Pemphigus using images, we suggested machine learning-based techniques. This proposed system uses a large dataset collected from various web sources to detect Pemphigus. Augmentation has been applied on our dataset using techniques such as zoom, flip, brightness, distortion, magnitude, height, width to enhance the breadth and variety of the dataset and improve model’s performance. Five popular machine learning algorithms has been employed to train and evaluate model, these are K-Nearest Neighbor (referred to as KNN), Decision Tree (DT), Logistic Regression (LR), Random Forest (RF), and Convolutional Neural Network (CNN). Our outcome indicate that the CNN based model outperformed the other algorithms by achieving accuracy of 93% whereas LR, KNN, RF and DT achieved accuracies of 78%, 70%, 85% and 75% respectively.
Pęcherzyca to choroba skóry, która może powodować poważne uszkodzenia ludzkiej skóry. Pęcherzyca może powodować inne problemy, w tym bolesne plamy i zakażone pęcherze, które mogą skutkować sepsą, utratą masy ciała i łaknienia, co może zagrażać życiu, próchnicą zębów i chorób dziąseł. Wczesne wykrycie pęcherzycy może uchronić przed śmiertelną chorobą. Uczenie maszynowe może zaoferować wysoce efektywne podejście do podejmowania decyzji i precyzyjnego prognozowania. Sektor opieki zdrowotnej doświadcza niezwykłych postępów dzięki wykorzystaniu technik uczenia maszynowego. Dlatego do identyfikacji pęcherzycy za pomocą obrazów zaproponowano techniki oparte na uczeniu maszynowym. Proponowany system wykorzystuje duży zbiór danych zebranych z różnych źródeł internetowych do wykrywania pęcherzycy. W zbiorze danych zastosowano augmentację przy użyciu technik takich jak powiększanie, odwracanie, zmiana jasności, zniekształcenie, zmiana wielkości, wysokość i szerokości, aby zwiększyć zakres i różnorodność zbioru danych oraz poprawić wydajność modelu. Do uczenia i oceny modelu wykorzystano pięć popularnych algorytmów uczenia maszynowego, są to: K-Nearest Neighbor (określany jako KNN), drzewo decyzyjne (DT), regresja logistyczna (LR), las losowy (RF) i konwolucyjną sieć neuronowa (CNN). Uzyskane wyniki wskazują, że model oparty na CNN był lepszy od innych algorytmów, osiągając dokładność na poziomie 93%, podczas gdy LR, KNN, RF i DT osiągnęły dokładność odpowiednio 78%, 70%, 85% i 75%.

Introduction and aim. Arterial stiffness (AS) has been associated with reduced cardiorespiratory fitness (CRF). The aim of this study was to verify if there is a relationship between augmentations index (AIx), as an index for AS assessment, and CRF in individuals with type 2 Diabetes Mellitus (T2DM). Material and methods. Observational cross-sectional study including 32 individuals diagnosed with T2DM who performed two evaluations: 1. Arterial stiffness assessment using SphygmoCor and 2. CRF throughout a cardiopulmonary exercise test on a treadmill ergometer. Oxycon Mobile® device was used to obtain oxygen uptake consumption at peak (V˙O2peak); oxygen uptake efficiency slope (OUES) determined by linear regression in reason of the logarithmic transformation of the ventilation and V˙O2 obtained every minute of exercise test. Statistical analysis comprised Pearson’s Correlation and linear regression analysis performed in SigmaPlot. Results. There was a significant correlation between AS and CRF: AIx and OUES; AIx@75 and; OUES. In linear regression, AIx was determinant for V˙O2peak and OUES – AIx and; AIx@75 and V˙O2peak. Conclusion. AS was associated with CRF in individuals with T2DM. These results contribute to the body of evidence linking arterial functional properties to CRF and suggests greater attention for this important index.

Opis:
The rapid increase of technologically enhanced listening platforms gives listeners access to music with ever-increasing ease and ubiquity, giving rise to the suggestion that we should now conceptualize music as a resource similar to water; something that is utilized to achieve everyday goals. This paper proposes that music is a utilitarian resource employed by listeners to augment cognitive, emotional, behavioral, and physiological aspects of the self. To better explore these notions this paper examines the potential role of the “functions of music,” first espoused by Alan P. Merriam in 1964. Merriam suggested music has a situational use and an underlying function (music’s ability to alter the self through listening). The research presented here asserts that listeners interact with specific musical materials to achieve or orientate themselves towards contextually-rooted goals. Reinforcing Tia DeNora’s suggestion that music is a “technology of the self” this research presents the results of a 41 publication meta-analysis exploring the possible functions of music. The resultant Aggregate Thematic Functions Framework (ATF framework) identifies 45 possible utilitarian functions of music, spread across five domains of action. The framework also proposes a meta-domain and an emotional sub-domain

Opis:
Researchers address the generalization problem of deep image processing networks mainly through extensive use of data augmentation techniques such as random flips, rotations, and deformations. A data augmentation technique called mixup, which constructs virtual training samples from convex combinations of inputs, was recently proposed for deep classification networks. The algorithm contributed to increased performance on classification in a variety of datasets, but so far has not been evaluated for image segmentation tasks. In this paper, we tested whether the mixup algorithm can improve the generalization performance of deep segmentation networks for medical image data. We trained a standard U-net architecture to segment the prostate in 100 T2-weighted 3D magnetic resonance images from prostate cancer patients, and compared the results with and without mixup in terms of Dice similarity coefficient and mean surface distance from a reference segmentation made by an experienced radiologist. Our results suggest that mixup offers a statistically significant boost in performance compared to non-mixup training, leading to up to 1.9% increase in Dice and a 10.9% decrease in surface distance. The mixup algorithm may thus offer an important aid for medical image segmentation applications, which are typically limited by severe data scarcity.

Female breasts have been admired for a variety of reasons throughout the ages. This can influence a preoccupation with breast size. As a result, augmentation mammoplasty (AM) has become a sought-after elective cosmetic procedure, especially in western culture. Research has confirmed the psychological benefits of AM, but it has also shown that some women with a self-perceived inadequate breast size who request AM can present with psychological problems. Likewise, authorities agree that the diagnosis of breast cancer which remains one of the most frequently diagnosed cancers among women worldwide, can have an adverse effect on women psychologically, and that the number of patients who live with the psychological sequelae of both the disease and its treatment continue to rise. Several factors relate to psychological distress in women coping with these issues. In particular, self-esteem and body image-related problems faced by women can add a burden to their psychological well-being. This article reviews some of these issues and psychological treatment options to enhance women’s adjustment in this regard.

Opis:
Background: Restoration of the masticatory function in patients with edentulous posterior maxilla is often challenging due to the severe atrophy of the alveolar ridges and proximity of the maxillary sinus, resulting in insufficient bone quantity for implant-supported dentures. Aim: The purpose of this study was to analyze the changes in Schneiderian membrane thickness after lateral sinus floor augmentation (LSFA) using cone beam computed tomography (CBCT). Material and methods: WLSFA procedures using different bone grafting materials were performed in 87 patients, operated on in two clinical institutions from 2016 to 2018. CBCT examination was performed in all patients before the LSFA procedure, at 1 month after surgery, and after 6 months, before implant placement or loading. Results: Minor r adiological changes in mucous membrane morphology were observed preoperatively in 17.1% of patients. Postoperative CBCT in the early postsurgical period demonstrated that the number of intact non-specific sinuses decreased significantly, i.e. from 86.7% to 26.7%. The number of cases with local hypertrophia of the mucous membrane increased from 20.3% to 26.7%. Mucosal thickening was observed in 41.7% vs 7.5%. The number of intact sinuses increased to 57.8%. The number of cases with local membrane hypertrophia also increased – to 37.4%. The number of cases with mucosal thickening or fluid accumulation decreased significantly to 11.8 and 5.3% respectively. In 2 cases the development of chronic sinusitis required secondary surgeries. Conclusion: The present retrospective study revealed that minor radiological changes in the morphology of the maxillary sinus mucosa were observed preoperatively in 17.1% of patients who underwent LSFA procedures. In the early and late postoperative period their frequency increased to 68.5% and 47.1%, respectively. However, the clinical signs of sinusitis developed only in 19.26% of patients. No significant correlations were found between the frequency and severity of postoperative radiological changes and residual bone height, sinus anatomy, initial state of the mucous membrane and type of the grafting material.

Deposition defects like porosity, crack and lack of fusion in additive manufacturing process is a major obstacle to commercialization of the process. Thus, metallurgical microscopy analysis has been mainly conducted to optimize process conditions by detecting and investigating the defects. However, these defect detection methods indicate a deviation from the operator’s experience. In this study, artificial intelligence based YOLOv3 of object detection algorithm was applied to avoid the human dependency. The algorithm aims to automatically find and label the defects. To enable the aim, 80 training images and 20 verification images were prepared, and they were amplified into 640 training images and 160 verification images using augmentation algorithm of rotation, movement and scale down, randomly. To evaluate the performance of the algorithm, total loss was derived as the sum of localization loss, confidence loss, and classification loss. In the training process, the total loss was 8.672 for the initial 100 sample images. However, the total loss was reduced to 5.841 after training with additional 800 images. For the verification of the proposed method, new defect images were input and then the mean Average Precision (mAP) in terms of precision and recall was 0.3795. Therefore, the detection performance with high accuracy can be applied to industry for avoiding human errors.

Aim: We assessed long-term outcomes of vocal fold augmentation with calcium hydroxylapatyte performed under local anesthesia. Material and methods: We enrolled 17 patients with glottic insuf ficiency due to unilateral laryngeal paralysis or insuf ficiency of internal laryngeal muscles (10 women, 17 men; mean age, 57.6±17.7 years; median age, 61 years; age range, 32-83 years). All patients underwent laryngeal augmentation under local anesthesia, through the oral cavity, with calcium hydroxylapatite (Radiesse) injected laterally to the vocal folds, unilaterally or bilaterally. We assessed voice quality before laryngeal augmentation and at 3 and 12 months. To that end, we performed videolaryngostroboscopy, perceptual assessment of voice, acoustic analyses, and aerodynamic assessments; moreover, participants completed the Voice-Related Quality of Life (VRQoL) questionnaire. Results: Af ter 3 months, we observed a statistically significant improvement on the perceptual assessment of voice with regard to the G and A parameters, and good outcomes were also observed at 12 months. On the acoustic analyses, MDVP_Jitt, MDVP_Shim, and MDVP_NHR improved to 2.5, 5, and 0.1, respectively, at 3 months, and to 1.9, 3.6, and 0.1, respectively, at 12 months. MPTa was prolonged to 12.2s and 11.9s at 3 and 12 months, respectively. Voice intensity improved from 67dB(A) before augmentation to 68dB(A) and 71dB(A) at 3 and 12 months, respectively. VRQoL scores improved to 19.5 and 20 at 3 and 12 months, respectively. Discussion: Laryngeal augmentation with calcium hydroxylapatite performed under local anesthesia is associated with good long-term outcomes.

The attempt is made towards compiling and classifying derivatives formed on the basis of nouns, adjectives and verbs according to morphological criteria. Additionally, the derived units subject to analysis are required to contain augmentative, both augmentative and pejorative, as well as ironical and downgrading formatives. The analysis is conducted with the aid of data drawn from interviews and short narratives delivered by hunters (both web-based and available in paper form). Handbooks and dictionaries of hunting lexis and practice were precious tools accordingly. Polish language is demonstrated to boast a large number of modifying derivatives that have an expressive value. Not only is this specialized technical lexis used to convey information in straightforward communicative circumstances. Above all, its significance lies in enabling users to share experience, exchange opinions and get rid of emotions. In point of fact, both individual and collectively performed acts of hunting are emotion-laden. That is why, aside from features inherent in every kind of specialized code (economy, precision and highly routinized manners of encoding), a bundle of peculiar features are found in hunting lexis: a significant degree of subjectivity that becomes most obvious in an extensive use made of affectively marked derivation.

Consequences of Delays
Ionospheric Delay
satellite based augmentation system (SBAS)
Opis:
In SBAS (satellite‐based augmentation system), it is important to estimate ionospheric delay accurately to guarantee userʹs accuracy and integrity. Grid based ionospheric models are generally used to estimate ionospheric delay for SBAS. In grid based model, SBAS broadcasts vertical ionospheric delays at the grid point, and users get their ionospheric delay by interpolating those values. Ionospheric model based on spherical harmonics function is another method to estimate ionospheric delay. This is a function based approach and spherical harmonics function is a 2‐D fourier series, containing the product of latitude dependent associated Legendre functions and the sum of the longitude dependent sine and cosine terms. Using ionospheric delay measurements, coefficients for each spherical harmonics functions are estimated. If these coefficients are known, user can reconstruct ionospheric delay. In this paper, we consider the spherical harmonics based model and propose a ionospheric delay estimation strategy for SBAS that can be used to mitigate ionospheric delay estimation error, especially in storm condition. First, coefficients are estimated under initial order and degree. Then residual errors for each measurement are modeled by higher order and degree terms, then coefficients for these terms are estimated. Because SBAS message capacity is limited, in normal condition, initial order terms are only used to estimate ionospheric delay. If ionospheric storm is detected and there is need to mitigate the error, higher order terms are also used and error can be decreased. To compare the accuracy of spherical harmonics based model with grid based model, some post‐processing test results are presented. Raw observation data is obtained from RINEX format and the root mean square(RMS) and max value of residual errors are presented.

Thermal augmentation in flat tube of car radiator using different nanofluids has been performed more often, but use of artificial roughness has been seldom done. Artificial roughness in the form of dimple is used in the present research work. Present study shows the impact of dimple shaped roughness and nanofluid (Al2O3/pure water) on the performance of car radiator. The pitch of dimples is kept at 15 mm (constant) for all the studies performed. The Reynolds number of the flow is selected in the turbulent regime ranging from 9350 to 23 000 and the concentration of the nanofluid is taken in the range of 0.1–1%. It has been found that the heat transfer rate has improved significantly in dimpled radiator tube on the expense of pumping power. Furthermore, the heat transfer rate also increases with increase in nanoparticle concentration from 0.1% to 1.0%. The highest heat transfer enhancement of 79% is observed at Reynolds number 9350, while least enhancement of 18% is observed for Reynolds number of 23 000.

Opis:
In aetiopathogenesis of schizophrenia the key role is played by dopaminergic, but also serotoninergic, glutamatergic systems as well as cholinergic neurons. Donepezil is a mixed inhibitor of acetylcholinesterase, selectively inhibiting acetylcholinesterase. A review of the studies, in which donepezil was used for augmentation of antipsychotic treatment does not provide explicit information on the effects of such procedures within a change of scores on PANSS. Pursuant to the assumptions of hypoglutamatergic hypothesis of schizophrenia, the transmission was stimulated within this system. To its stimulation through NMDA receptor among others glycine was used, i.e. prevalent amino acid of the simplest structure, the basic transmitter of glycinergic neurons counted among class I – neurotransmitters, additionally functioning as a coagonist and modulator, also within the glutamatergic system. In 2005 a meta-analysis of studies appeared, from which it results that glycine and D-serine significantly decrease the severity of negative symptoms. The study was aimed at establishing whether or not adjunctive glycine or donepezil applied for 6 weeks with antipsychotic treatment statistically significantly affect a change in the severity of positive symptoms, negative symptoms, general psychopathology in patients at a stable period of the disease. Subjected to the study was a group of 62 patients aged 18-55 years, suffering from paranoidal schizophrenia (DSM-IV) at the mental condition stabilised for at least half a year, without a change in the type and dose of antipsychotic drug at that time. The following methods were used: 1) confirmation of stabilisation of the mental condition and stable pharmacotherapy for the required period according to analysis of medical documentation, interview and evaluation of the current status; 2) augmentation of the hitherto applied antipsychotic treatment by adding donepezil or glycine and 3) evaluation of the severity of negative symptoms, positive symptoms and general psychopathology (PANSS) before and after 6 week augmentation by donepezil or glycine and occurrence of adverse symptoms. Results: Statistically significant differences were obtained after 6 weeks in a group treated with antipsychotic drugs and glycine (primarily within negative symptoms and general psychopathology, less within positive symptoms), whereas in the group additionally treated with donepezil no such differences were found.
W etiopatogenezie schizofrenii kluczową rolę odgrywa układ dopaminergiczny, ale swój udział mają także układ serotoninergiczny i glutaminianergiczny oraz neurony cholinergiczne. Donepezil jest mieszanym inhibitorem acetylocholinesterazy selektywnie hamującym raczej acetylocholinesterazę. Przegląd badań, w których do augmentacji leczenia przeciwpsychotycznego stosowano donepezil, nie dostarcza jasnych informacji na temat efektów takiego postępowania w zakresie zmiany punktacji w podskalach PANSS. Zgodnie z założeniami hipoglutaminianergicznej hipotezy schizofrenii stymulowano transmisję w obrębie tego układu. Do jego pobudzenia poprzez receptor NMDA stosowano m.in. glicynę – aminokwas o najprostszej budowie i szerokim rozpowszechnieniu, podstawowy przekaźnik neuronów glicynergicznych, zaliczany do klasy I neurotransmiterów, pełniący ponadto funkcję koagonisty i modulatora, m.in. w obrębie układu glutaminianergicznego. W 2005 r. ukazała się metaanaliza badań, z której wynika, że glicyna i D-seryna istotnie zmniejszają nasilenie objawów negatywnych. Celem badania było ustalenie, czy dołączenie przez okres 6 tygodni glicyny lub donepezilu do dotychczasowego leczenia przeciwpsychotycznego w sposób istotny statystycznie wpływa na zmianę nasilenia objawów pozytywnych, negatywnych, ogólnej psychopatologii u pacjentów w stabilnym okresie choroby. Badaniu poddano grupę 62 osób w wieku 18-55 lat, chorych na schizofrenię paranoidalną (DSM-IV), w stanie psychicznym ustabilizowanym od co najmniej pół roku, bez zmiany w tym czasie rodzaju i dawki leku przeciwpsychotycznego. Zastosowano następujące metody: 1) potwierdzenie stabilizacji stanu psychicznego oraz stałej farmakoterapii przez wymagany okres na podstawie analizy dokumentacji medycznej, wywiadu i oceny aktualnego stanu; 2) augmentacja dotychczasowego leczenia przeciwpsychotycznego przez dodanie donepezilu lub glicyny oraz 3) ocena nasilenia objawów negatywnych, pozytywnych i psychopatologii ogólnej (PANSS) przed i po 6 tygodniach augmentacji donepezilem lub glicyną i występowania objawów niepożądanych. Wyniki: Istotne statystycznie różnice uzyskano po 6 tygodniach w grupie leczonych lekami przeciwpsychotycznymi oraz glicyną (przede wszystkim w zakresie objawów negatywnych i psychopatologii ogólnej, mniejsze w zakresie objawów pozytywnych), natomiast w grupie leczonej dodatkowo donepezilem nie stwierdzono takich różnic.

Opis:
This paper presents a case of a patient with invasive ductal breast cancer following breast augmentation. Following breast implants rupture in March 2013 the breast implants have been removed – histopathological examination revealed leaked silicone with inflammatory infiltration, without evidence of cancerous lesions. Diagnostic imaging revealed multiple encapsulated silicone particles and clusters of post-inflammatory macrocalcifications in both breasts. In January 2014 the patient presented with symptoms of massive inflammation of the left breast. Following surgical consultation the patient had undergone radical left-sided mastectomy with lymphadenectomy. Postoperative histopathological examination revealed a multifocal advanced invasive ductal cancer G3 pT3pN3a (vascular invasion, metastases in 11 of 12 examined axillary lymph nodes). Following surgery the patient was qualified for further treatment – chemotherapy, radiotherapy, hormone therapy. The discussion includes a review of literature on the risk evaluation of co-occurrence of breast cancers in women with silicone breast implants and presents diagnostic challenges of breast cancer in this patient group.

Opis:
Data augmentation is one of the ways to deal with labeled data scarcity and overfitting. Both of these problems are crucial for modern deep-learning algorithms, which require massive amounts of data. The problem is better explored in the context of image analysis than for text; this work is a step forward to help close this gap. We propose a method for augmenting textual data when training convolutional neural networks for sentence classification. The augmentation is based on the substitution of words using a thesaurus as well as Princeton University's WordNet. Our method improves upon the baseline in most of the cases. In terms of accuracy, the best of the variants is 1.2% (pp.) better than the baseline.

Opis:
Przeszczep tkanki kostnej jest powszechnie znaną i skuteczną metodą wypełniania ubytków osteolitycznych powstałych w wyniku urazów, działań chirurgicznych oraz stanów chorobowych (torbiele, zapalenie przyzębia). Jednym z kluczowych problemów związanych z tym zabiegiem jest ograniczenie ilości materiału możliwego do pobrania przez operatora od pacjenta. Ponadto zabieg na miejscu dawczym wiąże się z dodatkową raną kostną oraz może stanowić problem zarówno estetyczny, jak i funkcjonalny. Rozwiązaniem wymienionych problemów może być zastosowanie autogennych tkanek twardych zęba pacjenta. Zawierają one biozgodną macierz zębinową charakteryzującą się wysokiego rzędu podobieństwem histologicznym i biochemicznym do tkanki kostnej. Możliwość zastosowania materiału zębowego do wypełniania ubytków kostnych nie jest rozwiązaniem nowym – temat ten podejmowany był już w 1967 roku w badaniach nad właściwościami osteogennymi demineralizowanego materiału zębowego i rozwijany jest po dziś dzień. Obecnie do odbudowy tkanki kostnej wykorzystywany jest również materiał o pełnej zawartości frakcji mineralnej, którego użycie znacznie skraca czas zabiegu. W pracy przedstawiono właściwości autogennego materiału zębowego oraz sposób jego uzyskiwania.
Bone tissue graft is a commonly recognised and efficient method of filling osteolitic cavities resulting from injuries, surgical procedures and lesions (cysts, periodontitis). One of the most crucial problems related to this procedure is the limitation of grafting material obtainable from the patient’s tissues. Moreover, graft donoring site operation is associated with an additional bone wound and might result in an aesthetical as well as functional problems. A solution for presented difficulties may be the use of autogenous tooth’s hard tissues, which contain biocompatible dentin matrix of a high histological and biochemical similarity to bone tissue. The possibility of using dental material for filling bone cavities is not a new solution – the osteogenic properties of demineralised dentin material were already examined in 1967 and this concept is still developing. Currently, a material with a full content of the mineral fraction is used for regeneration of bone tissues, which shortens the time of procedure significantly. The paper presents the properties of autologous dental material and a method of its obtaining.

Opis:
Introducing variation in the training dataset through data augmentation has been a popular technique to make Convolutional Neural Networks (CNNs) spatially invariant but leads to increased dataset volume and computation cost. Instead of data augmentation, augmentation of feature maps is proposed to introduce variations in the features extracted by a CNN. To achieve this, a rotation transformer layer called Rotation Invariance Transformer (RiT) is developed, which applies rotation transformation to augment CNN features. The RiT layer can be used to augment output features from any convolution layer within a CNN. However, its maximum effectiveness is shown when placed at the output end of final convolution layer. We test RiT in the application of scale-invariance where we attempt to classify scaled images from benchmark datasets. Our results show promising improvements in the networks ability to be scale invariant whilst keeping the model computation cost low.

Opis:
Purpose: The conventional screw is unable to provide enough screw-bone interface strength for osteoporotic cencellous bone, and complications resulting from loosening or failure of the implants remain a significant clinical problem. Hence, the purpose of this study is to investigate pullout strength and energy in three types of the pedicle screws, including conventional solid pedicle screw, cannulated pedicle screw, and cannulated pedicle screw with a central pin, using osteoporotic sawbone test block with different bone cement volumes through pullout force testing. Methods: The control group (n = 15) of the osteoporotic sawbone test block includes groups A, B, and C to reflect three types of the pedicle screws without bone cement augmentation. The cemented group (n = 45) of the osteoporotic sawbone test block includes groups D1, D2, D3, E1, E2, E3, F1, F2, and F3 to reflect three types of the pedicle screws with PMMA bone cement of 2, 3, and 4 mL augmentation. Results: The results showed that the pullout strength and energy in the cemented group were significantly larger than that in the control group. Moreover, the best performances of the pullout strength and energy in the cemented group were evidenced obviously in the case of cannulated pedicle screw with a central pin with 4 mL bone cement augmentation. Conclusions: This study concludes that cement argumentation in the cannulated pedicle screw with a central pin can increase a pullout strength of pedicle screw for severe osteoporotic patients while bone cement of injective volume is limited.

Opis:
The purpose of this study was to investigate pullout strength of three types of pedicle screws with and without cement augmentation in osteoporotic bone using finite element analysis. Methods: Twelve 3D finite element models were created to investigate the effect of pullout strength when comparing between pedicle screw types and bone cement clouds. The bottom side of bone block model was constrained and U-shape head was applied 1 mm in direction of longitudinal axis of pedicle screw to perform pullout resistance. The material properties of the FEA was set as linear elastic, homogenous, isotropic condition. The element sensitivity of convergence testing has been performed and variation of the sequential analytical results was less than 3%. Results: The results showed that the maximum total reaction force (133.8 N) was detected in the model of cannulated pedicle screw combined with a central pin with 4 ml cement augmentation, but, in contrast, the minimum total reaction force (106.8 N) was discovered in the model of cannulated pedicle screw without cement. A strong relationship (r = 0.9626) is found in comparison with the biomechanical results between pullout strength of sawbone testing and reaction forces of the FEA. Conclusions: The study concludes that the cannulated pedicle screw can not only provide an inner guider for cement flow and increase bending resistance (deflection effect) when a central pin is selected, but also can improve the pullout strength in the osteoporotic bone to add cement augmentation. The design of the cannulated pedicle screw is suggested for poor bone quality to change pullout failure.

Numerical predictions of heat transfer under laminar conditions in a square duct with ribs are presented in this paper. Ribs are provided on top and bottom walls in a square duct in a staggered manner. The flow rates have been varied between Reynolds number 200 and 600. Various configurations of ribs by varying length, width and depth have been investigated for their effect on heat transfer, friction factor and entropy augmentation generation number. Further artificial neural network integrated with genetic algorithm was used to minimize the entropy augmentation generation number (performance factor) by selecting the optimum rib dimensions in a selected range. Genetic algorithm is compared with microgenetic algorithm to examine the reduction in computational time for outlay of solution accuracy.

Introduction: We present a single surgeon’s experience of open augmentation rhinoplasty with autogenous
L-shaped costal cartilage grafts, with long-term patient-reported outcome data. We highlight the salient operative steps and outline the peri-operative care required to optimise outcomes. Materials and Methods: A retrospective review of eleven such augmentation rhinoplasties performed between 2008 and 2016 was undertaken. Indications included saddle nose deformity [granulomatosis with polyangiitis (n=7) and relapsing polychondritis (n=1)], post-traumatic nasal collapse (n=1) and advanced cosmetic westernisation of the nose (n=2). Long-term patient-reported outcome was assessed with a patient questionnaire. Results: All patients achieved marked improvement in nasal position, shape and function. There was no cartilage exposure, warping or resorption and no recurrent deformities. One patient’s dorsal graft was fractured two years later during an ophthalmological procedure and the deformity was re-corrected successfully, again with the above technique. Average follow up was 5.2 years. Of the nine patients who responded to the follow-up questionnaire, 100% were satisfied with their nasal appearance. 100% of responders at follow-up reported that they have had no problems relating to their nose (n=9). Discussion: L-shaped costal cartilage grafts provided a reliable, reproducible approach in augmentation rhinoplasty for disparate indications (inflammatory, traumatic and cosmetic) in the hands of a low-volume operator. With careful patient selection and planning, this technique can provide pleasing aesthetic outcomes and high patient satisfaction, with good long-term outcomes.

Opis:
In present article a mathematical model of arc shape wire roughened solar air heater, on the basis of energy and exergy output rates, entropy generation rate and augmentation entropy generation number, has been developed. A parametric study leading to entropy generation minimization has also been performed. In the analysis the geometric and operating parameters which have been considered as variable are: inlet air temperature, duct depth, collector width to duct depth ratio, mass flow rate per unit collector area, and temperature rise parameter. Results have been presented to see the effects of these values on the energy and exergy output rates of the roughened solar air heater. Effect of different values of wire rib roughness parameters on entropy generation has also been presented. Finally, design curves and optimization for different rib roughness parameters on the basis of minimum entropy generation number with temperature rise parameter, have been presented and optimum values also have been found out 0.004 to 0.010 (Km2 )/W. The entropy generation rate obtained for the system, in the present work has been compared with those obtained for solar air heater with different roughness geometries on absorber plates available in the literature for common roughness parameters and operating parameters which validate the present results.

Opis:
This paper presents original researches and analysis of EGNOS (European Geostationary Navigation Overlay Service) due to readiness for Approach Procedures with Vertical Guidance (APV) implementation and development for small and medium airports on Polish territory according to present situation in the western part of Europe. Improving safety, availability, usefulness and cost-effectiveness for aviation transport sector. This work carries out a detailed analysis of the parameters describing and characterizing each augmentation navigational satellites system: accuracy, integrity, continuity and availability. Faults has been pointed out and shortcomings of EGNOS factors according to improvement air transport safety in the most sensitive landing phases. The validated Approach Procedures with Vertical Guidance, using Satellite-Based Augmentations System is paving the way for flying Instrument Landing System type approaches to small and medium airports in the western part of Europe independently of groundbased infrastructure. The instrument APV procedures consists of four phases of flight: Initial Approach, Intermediate Approach, Final Approach and Missed Approach – parts of approach segments. SBAS (Satellite Based Augmentation System) seems to be the first satellite based system that can support FAS (Final Approach Segment) which is the most “sensitive”, important and dangerous part of the instrumental approach procedures based on aircraft’s avionics equipment most time without vertical and horizontal visibility. EGNOS augments the GPS system in order to meet the necessary: accuracy, integrity, availability, continuity envisaged for APV procedures [9]. APV procedure based on EGNOS system is recently the only low-cost chance for small and medium Polish airports development in the aviation transport sector, according to extension and improving augmentation system factors mentioned above.
W artykule przedstawione zostały oryginalne badania i analiza system EGNOS (European Geostationary Navigation Overlay Service) w odniesienu do implementacji i rozwoju Procedur Podejścia do Lądowania z Prowadzeniem Pionowym w małych i średnich portach lotniczych na terenie Polski, biorąc pod uwagę stan w Europie Zachodniej. Poprawiając tym samym bezpieczeństwo, dostępność, użytkowość i koszty eksploatacji w sektorze transport powietrznego. Praca ta przedstawia dokładną analizę czynników opisujących każdy system wspomagania satelitarnego: dokładność, wiarygodność, ciągłość I dostępność. Niedoskonałości systemu zostały przedstawione w odniesieniu do poprawy bezpieczeństwa transportu powietrznego w najdelikatniejszej fazie lotu – podejścia do lądowania. Powyższa procedura z wykorzystaniem system wspomagającego otwiera szansę rozwoju małym i średnim portom lotniczym w Europie Zachodniej uniezależniając podejście do lądowania od infrastruktury lotniskowej. Podejście instrumentalne APV składa się z czterech faz lotu: Podejście Początkowe, Podejścia Pośredniego, Podejścia Końcowego, Odlotu po Nieudanym Podejściu. System wspomagania satelitarnego, jako pierwszy wspomóc może także fazę Podejścia Końcowego, która jest najniebezpieczniejszą, najważniejszą fazą opartą na urządzeniach pokładowych w większości bez widoczności terenu. EGNOS wspomaga działanie GPS poprawiając niezbędne czynniki: dokładność, wiarygodności, dostępności, ciągłości przewidzianych w procedurach APV. Podejście oparte o EGNOS jest jedyną, niedrogą szansą dla małych i średnich polskich portów lotniczych, na rozwój w sektorze transportu powietrznego w nawiązaniu do rozszerzenia i poprawy czynników wyżej wymienionych.

Opis:
Nowadays, it is a fact that Global Navigation Satellite Systems (GNSS) have become the primary means of obtaining Position, Navigation and Timing (PNT) information at sea. Most of the ships in the world are equipped with GNSS receivers. And currently these users take advantage of different augmentation systems such as DGNSS or SBAS/EGNOS, as they provide an adequate answer, especially in terms of accuracy and integrity. To take advantage of this improved accuracy, direct access to EGNOS in vessels can be achieved through EGNOS-enabled navigation receivers and EGNOS-enabled AIS transponders. Therefore, the natural question is: Are those GNSS receivers SBAS (EGNOS) enabled? In most cases they are; SBAS is being used. This paper provides an analysis of the number of onboard devices, mainly devoted to navigation purposes and AIS transponders, which are SBAS compatible.

Opis:
The maritime sector was one of the first communities that recognized and exploited the opportunities and advantages provided by Global Navigation Satellite Systems (GNSS). In fact, GNSS have become the primary means of obtaining Position, Navigation and Timing (PNT) information at sea. Most of the ships in the world are equipped with GNSS receivers. GPS provides the fastest and most accurate method for mariners to navigate, measure speed, and determine location. However, its performance can be enhanced by taking advantage of augmentation systems such as differential GNSS or Satellite-Based Augmentation Systems (SBAS/EGNOS), especially in terms of accuracy. Direct access to EGNOS in vessels can be achieved through EGNOS-enabled navigation receivers and EGNOS-enabled AIS transponders. This paper provides an analysis of the number of onboard devices, mainly devoted to navigation purposes, and AIS transponders which are SBAS compatible. In addition, other equipment using GNSS positioning in the maritime and inland waterways domains are also considered for the analysis of SBAS compatibility, including inland AIS, Portable Pilot Units (PPUs) and Dynamic Positioning (DP) equipment. A first survey was done in 2017 to have an overview of the percentage of SBAS enabled devices available in the maritime market [8]. Since then, the analysis has been yearly updated to understand the market evolution in terms of SBAS compatibility and its main results are summarised in this paper.

Opis:
For nearly the entire post-World War II period, naval and air navigation relied primarily on ground-based radionavigation systems. However, the spontaneous development of satellite systems gradually led to their disappearance. They are currently used partly in air operations and marginally in maritime navigation in some areas around Asia, in Russia and in the Middle East. However, at the beginning of the 21st century, the threat of effective interference with satellite systems began to be raised, which led to an increased interest in restoring or upgrading ground-based systems as backup systems in the Western world. In this context, the approach of Russia is interesting, as it is associated with the vast majority of deliberate GPS interference. There are reports in the world literature that various ground-based radionavigation systems operating in Russia are still observed. The article analyses, on the basis of the few available sources, information on the ALFA system, about which the least is known, and there are many indications that it is ready for use.

Opis:
Dysfunkcja podniebienno-gardłowa (DPG) jest to zaburzenie funkcji zwieracza podniebienno-gardłowego (ZPG), którego zadaniem jest oddzielanie jam nosa od jamy ustnej w trakcie aktu mowy, dmuchania, ssania czy wymiotowania. Nieprawidłowe działanie zwieracza może doprowadzać do niezrozumiałej mowy (nosowanie otwarte) oraz przecieku powietrza i treści pokarmowych do jam nosa. Dysfunkcja wpływa również niekorzystnie na proces połykania oraz na wentylację ucha środkowego. Niniejsze opracowanie opisuje podstawy anatomiczno-patofizjologiczne tego schorzenia oraz uwzględnia niełatwy proces diagnostyczny, a także leczenie opisywanego problemu. Przy ocenie pacjentów zarówno przed, jak i po leczeniu stosować należy skale obiektywizujące objawy prezentowane przez dzieci z opisywaną dysfunkcją. Zaproponowany schemat postępowania uwzględnia autorskie elementy diagnostyczne (wyselekcjonowaną próbkę mowy), opracowane przez autorów dla potrzeb leczenia pacjentów z DPG, dostosowane do języka polskiego. Proponowany schemat diagnostyczno terapeutyczny stosowany jest w praktyce w ośrodku autorów od kilku lat. Opisano postępowanie terapeutyczne w zależności od nasilenia objawów oraz sposoby oceny dysfunkcji i wyników leczenia. W celu uzyskania optymalnych wyników leczenia konieczna jest ścisła współpraca laryngologów/chirurgów dziecięcych, foniatrów oraz logopedów.
Velopharyngeal dysfunction (VPD) is a disorder of the function of the velopharyngeal valve, whose task is to separate the nasal cavity from the oral cavity during the act of speech, blowing, sucking or vomiting. Incorrect sphincter function can lead to incomprehensible speech (open nasal speech) and leakage of air and fluid into the nasal cavities. The dysfunction also adversely affects the swallowing process and the ventilation of the middle ear. This study describes the anatomical and pathophysiological basis of this disease and takes into account the difficult diagnostic process as well as the treatment of the described problem. When evaluating patients, both before and after treatment, scales should be used to objectiveize the symptoms presented by children with the described dysfunction. The proposed procedure takes into account the author’s diagnostic elements (a selected speech sample), developed by the authors for the needs of treatment of patients with VPD adapted to the Polish language. The proposed diagnostic and therapeutic scheme has been used in practice in the authors’ center for several years. Therapeutic management was described depending on the severity of symptoms, as well as methods of assessing dysfunction and treatment results. In order to obtain optimal treatment results, close cooperation between laryngologists/pediatric surgeons, phoniatrists and speech therapists is necessary.

W artykule zawarto krótkie omówienie dwóch przykładowych narzędzi kierowania strefami krótkotrwałego parkowania oraz realizowanych przez te narzędzia funkcji. Po pierwsze zostanie przedstawiony prototyp systemu zbierającego informacje w czasie rzeczywistym dla pokazania stopnia zajętości strefy krótkotrwałego parkowania, Po drugie zostaną omówione wyniki wdrożonej w Wiedniu strategii, która polegała na wzroście opłat za parkowanie, aby wpływać na zachowania mieszkańców związane z parkowaniem. Przykłady te mogą być traktowane jako modelowe i stanowić wzór do naśladowania w innych miastach, jako że strefy krótkoterminowego parkowania i parkowanie z wykorzystaniem telefonu komórkowego są obecnie uważane za najnowocześniejsze w wielu miastach Europy i należy oczekiwać, że ich wykorzystanie będzie się rozprzestrzeniać dalej.
The paper will give an overview on the two examples of steering tools for short-term parking zones and its functions. First, a prototype of a real-time information system for showing the occupancy rate of short-term parking zones will be presented. Second, empirical parking survey was also used to evaluate the effects caused by another strategy implemented in Vienna, considering increase of parking fee, to influence the parking behaviour of citizens. These examples can serve as a role models for other cities, since short-term parking zones and mobile phone parking is state of the art in many European cities, and its use will increase elsewhere as well.

Opis:
The National Policy on Forests and the National Programme for the Augmentation of Forest Cover indicate regional needs, possibilities, legal and financial principles of afforestations as the most important elements of the improvement and maintenance of a good state of the country's environment. The documents put emphasis on the need for the establishment and restoration of afforestations between fields, however, neither the guidelines for their legal and administrative status nor sources of financing have been indicated. In many regions of the country, the large−scale afforestation are almost impossible, because high−quality soils are under agricultural production and the local communities lack the alternative means of living. Thus, the mid−field afforestations of a linear or small−surface type could be the only elements differentiating the landscape structure and acting as biogeochemical barriers. Their network perform the same complementary protective functions as forests or other semi−natural ecosystems. With a view to economising expenditures and intensifying effects aiming at the environment protection it is necessary to closely integrate the countryside environmental programmes including the establishment of biogeochemical barriers and afforestations. The principles of such integration and co−ordination of pro−ecological programmes of the landscape structure management should be laid down under a separate research project.

Opis:
In order to enable port operations, which require an accuracy of about 10cm, the German Aerospace Center (DLR) operates the Maritime Ground Based Augmentation Service (MGBAS) in the Research Port of Rostock. The MGBAS reference station provides GPS dual frequency code + phase correction data, which are continuously transmitted via an ultra-high frequency (UHF) modem. Up to now the validation of the MGBAS was rather limited. Either a second shore based station was used as an artificial user, or measurement campaigns on a vessel with duration of a few hours have been conducted. In order to overcome this, we have installed three separate dual frequency antennas and receivers and a UHF modem on the Stena Line ferry vessel Mecklenburg-Vorpommern which is plying between Rostock and Trelleborg. This paper concentrates on the analysis of the highly accurate phase based positioning with a Real Time Kinematic (RTK) algorithm, using correction data received by the UHF modem onboard the vessel. We analyzed the availability and accuracy of RTK fix solutions for several days, whenever the ferry vessel was inside the service area of the MGBAS.

In this paper are introduced alternative architectures for the novel development of the enhanced Global Maritime Distress and Safety System (GMDSS) satellite communication network and equipment within the Gostationary Erath Orbits (GEO and Non-GEO satellite constellations. Since its founding in 1959, the International Maritime Organization (IMO) and its member states, in close co-operation with the International Telecommunication Union (ITU) and other international organizations, notably the World Meteorological Organization (WMO), the International Hydrographic Organization (IHO), the International Mobile Satellite Organization (IMSO) and Cospas-Sarsat partners, have striven to improve maritime distress and safety radio and satellite communications, as well as general communications for operational and personal purposes. This paper also reviews the principal concept of the GMDSS network, an overview of existing LRIT and maritime Integrated Radio-Automatic Identification System (R-AIS) and Satellite-AIS (S-AIS) networks. In addition, new proposed by author networks of the Satellite Data Link (SDL), Maritime GNSS Augmentation Satellite Data Link (GASDL), Maritime Global Ship Tracking (GST), and Maritime Satellite Automatic Dependent Surveillance-Broadcast (SADS-B) are also described in this paper.
