    Opis:
    Reliability has been widely used as a potential indicator of the performance assessment for several real-life networks. Focus on a multistate transportation network in tourism (MTN), this study evaluates the reliability of the MTN as a basis for investigating the influence of transit time. Reliability is the probability to fulfill transportation demand under the given time threshold and budget limitation and evaluated at various levels of transit times. An algorithm, which employs the boundary points and recursive sum of disjoint products technique, is proposed to evaluate the MTN reliability. According to the obtained results, this paper analyzes the influence of transit times on MTN reliability. Particularly, this paper discusses and provides some suggestions about the appropriate transit time to maintain reliability. Decision-makers in the tourism industry also can predetermine the significant drops of reliability to improve the relevant transit times. Besides, the proposed investigation is indicated and proved through an illustrative example and a practical case.

    Opis:
    The hypertree can be defined in many different ways. Katona and Szabó introduced a new, natural definition of hypertrees in uniform hypergraphs and investigated bounds on the number of edges of the hypertrees. They showed that a $k$-uniform hypertree on $n$ vertices has at most \( \binom{n}{k−1} \) edges and they conjectured that the upper bound is asymptotically sharp. Recently, Szabó verified that the conjecture holds by recursively constructing an infinite sequence of $k$-uniform hypertrees and making complicated analyses for it. In this note we give a short proof of the conjecture by directly constructing a sequence of $k$-uniform $k$-hypertrees.

    Opis:
    The surface roughness and residual stress behavior in two types of SiNx/SiO2 dielectric quarter-wave stacks was investigated experimentally. A reactive pulsed magnetron sputtering system was used to prepare the SiNx/SiO2 multilayer thin films. The results show that SiNx/SiO2 quarter-wave stack with a buffer layer of MgF2 thin film can reduce the residual stress. The effect of aging on the residual stress in two quarter-wave stacks was also studied. We found that the residual stresses in both SiNx/SiO2 multilayer coatings are changed from a compressive state to a tensile stress state with increasing the aging time. The root mean square (RMS) surface roughness of MgF2/(SiNx/SiO2)22 and (SiNx/SiO2)22 quarter-wave stacks are 2.23 ± 0.22 nm and 2.08 ± 0.20 nm, respectively.

    Opis:
    ObjectivesWork-related stress (WRS) is significantly associated with health-related quality of life (HRQoL), but the amounts of evidence on differences of effort-reward imbalance (ERI) and job strain index (JSI) remain sparse and have limited generalizability. Therefore, we aimed to assess the association between ERI and JSI with HRQoL and assess the mediation effect of social support (JS) and over-commitment (OC) on this association in Taiwan’s civil servants.Material and MethodsA cross-sectional national survey was given to registered civil servants in Taiwan – 20 046 civil servants from 647 institutions were enrolled using multistage stratified random cluster sampling. A web-questionnaire collected demographic information, job characteristics, and different indexes of ERI and job-control-demand-support (JCDS) models. Structural equation model (SEM) was used to examine the association between ERI and JSI with HRQoL, and the mediation effect of JS and OC on the associations.ResultsIn the ERI model, ERI and OC were consistently negatively associated with the mental component score (MCS) (r = –0.46 and r = –0.37) and physical component score (PCS) (r = –0.45 and r = –0.34), which were higher than job demand (r = –0.28 and r = –0.22) and JSI (r = –0.38 and r = –0.29). Using hierarchical multiple regression analyses, ERI was significantly correlated with MCS and PCS, which was consistently higher than JSI. The ERI and JSI were significantly correlated with MCS (β = –0.170 and β = –0.140) and PCS (β = –0.150 and β = –0.082) using SEM analysis, whereas ERI was considerably higher than in JSI. In addition, OC and JS mediated the association between The ERI and JSI with HRQoL.ConclusionsWe found the ERI index is significantly correlated with HRQoL superior to JSI, in particular among Taiwan civil servants. Further longitudinal studies are needed to determine the causality and spatiotemporal relation of these differences.

    Gallium (Ga) is considered an important element in the semiconducting industry and as the lifespan of electronic products decrease annually Ga-containing effluent has been increasing. The present study investigated the use of biodegradable polymer powders, crab shell and chitosan, in the removal of Ga(III) ions from aqueous solution. Ga(III) biosorption was modeled to Lagergren-first, pseudo-second order and the Weber-Morris models. Equilibrium data was modeled to the Langmuir, Freundlich and Langmuir-Freundlich adsorption isotherms to determine the probable biosorption behavior of Ga(III) with the biosorbents. The biosorbents were investigated by Fourier Transform Infrared Spectroscopy, X-ray Diffraction and Scanning Electron Microscopy/Energy Dispersive Spectra analysis.

    Opis:
    Objectives The objective of this study was to assess sperm quality and deoxyribonucleic acid (DNA) integrity of coke oven workers exposed to polycyclic aromatic hydrocarbons (PAHs) as compared to control subjects. Material and methods The coke oven workers (N = 52) and administrative staff (N = 35) of a steel plant served as the exposed and control groups, respectively. Exposure to PAHs was assessed by measuring 1-hydroxypyren. Analysis of sperm quality (concentration, motility, vitality, and morphology) was performed simultaneously with sperm DNA integrity analysis, including DNA fragmentation, denaturation, bulky DNA adducts, and 8-oxo-7,8-dihydro-2’-deoxyguanosine (8-oxo-dGuo). A questionnaire was conducted to collect demographic and potential confounding data. Results The coke oven workers had lower percentages of sperm motility, vitality and normal morphology than the control group, but the difference was not significant. For DNA integrity, the coke oven workers had significantly higher concentrations of bulky DNA adducts and 8-oxo-dGuo than the control subjects (p = 0.009 and p = 0.048, respectively). However, DNA fragmentation percentages did not significantly increase as compared to those in the subjects from the control group (p = 0.232). There was no correlation between sperm quality parameters and DNA integrity indicators. Conclusions Occupational exposure of the coke oven workers to PAHs was associated with decreased sperm DNA integrity. Int J Occup Med Environ Health 2016;29(6):915–926

    Opis:
    Kilka skandali biznesowych zwróciło ostatnio uwagę na ciemną stronę przywództwa i na relację, jaka zachodzi pomiędzy liderami a szeregowymi pracownikami organizacji. Uwaga, jaką liderzy poświęcają względom etycznym, może wpływać na etykę podejmowanych decyzji przez szeregowych pracowników. Celem niniejszej pracy jest zbadanie związku pomiędzy osądem etycznym liderów i szeregowych pracowników organizacji. Rozwój osądu etycznego oceniono na przykładzie tajwańskich specjalistów ds. zakupów i zmierzono, korzystając z Defining Issues Test (testu określania problemów). Wnioski są takie, że liderzy osiągają wyższy wynik ogólny w zakresie rozwoju osądu etycznego niż szeregowi pracownicy i że istnieje pozytywne powiązanie pomiędzy rozwojem osądu etycznego u liderów i szeregowych pracowników. Ci ostatni wykazują wyższy stopień rozwoju osądu etycznego, jeżeli stopień ten jest wysoki również u ich liderów. Omówiono także, co wynika z  wniosków uzyskanych podczas badań.
    Several business scandals have highlighted the dark side of leadership and the relationship between leaders and followers. The ethical concerns of leaders may influence the ethical decision–making of followers. The purpose of this study is to explore the association between leaders' and followers' ethical judgment. A sample of Taiwanese purchasing professionals was assessed in terms of their ethical judgment development measured by the Defining Issues Test. The findings indicate that leaders will have higher overall scores for ethical judgment development than followers. There is a positive association between leaders' and followers' ethical judgment development. Followers will exhibit higher ethical judgment development when their leaders have higher ethical judgment development. Implications of research findings are also discussed.

    Opis:
    Sensitivity analysis of parameters is usually more important than the optimal solution when it comes to linear programming. Nevertheless, in the analysis of traditional sensitivities for a coefficient, a range of changes is found to maintain the optimal solution. These changes can be functional constraints in the coefficients, such as good values or technical coefficients, of the objective function. When real-world problems are highly inaccurate due to limited data and limited information, the method of grey systems is used to perform the needed optimisation. Several algorithms for solving grey linear programming have been developed to entertain involved inaccuracies in the model parameters; these methods are complex and require much computational time. In this paper, the sensitivity of a series of grey linear programming problems is analysed by using the definitions and operators of grey numbers. Also, uncertainties in parameters are preserved in the solutions obtained from the sensitivity analysis. To evaluate the efficiency and importance of the developed method, an applied numerical example is solved.

    Opis:
    According to complex geological conditions of working face E1108 in Xin-ji mine #2, loading and running characteristic of hydraulic support, influence of depression angle on mining pressure behaviors, as well as relation between advancing speed and the support loading were measured and analyzed. The results indicate that depression angle is inversely proportional to support resistance, in other words, larger depression angle area coincides with lower support resistance area. Moreover, support resistance is generally high when working face advancing speed is slow. Technologies for controlling hydraulic support stability such as improving advancing speed properly, controlling mining height and increasing support resistance are put forward based on research.
    Z uwzględnieniem złożonych warunków geologicznych w ścianie E1108 w kopalni Xin-Ji #2 dokonano pomiarów i analiz obciążenia i działania podpór hydraulicznych, zbadano wpływ kąta depresji na wielkość ciśnienia poziomu wydobywczego, a także zależność pomiędzy szybkością posuwania się na przodku i obciążeniem podpór. Wyniki analiz wskazują, że kąt depresji jest odwrotnie proporcjonalny do wytrzymałości podpory. Przy większych wartościach kąta depresji mamy do czynienia z obszarem gdzie wytrzymałość podpór jest niższa. Ogólnie rzecz biorąc, wytrzymałość podpory jest zazwyczaj wysoka dla niewielkich prędkości posuwania się na przodku. W pracy przedstawiono metody kontroli stabilności podpór hydraulicznych poprzez regulację szybkości posuwania się przodka, regulację wysokości wybierania oraz poprzez zwiększenie wytrzymałości podpór.

    Opis:
    To solve motor heating and life shortening of parallel switched reluctance generator (SRG) induced by uneven output currents due to different external characteristics, we generally adopt current sharing control (CSC) to make each parallel generator undertake large load currents on average to improve the reliability of parallel power generation system. However, the method usually causes additional loss of power because it does not consider the efficiency characteristics of each parallel generator. Therefore, with the efficiency expression for the parallel system of SRG established and analysed, the control strategy based on differential evolution (DE) algorithm is proposed as a mechanism by which to enhance generating capacity and reliability of multi-machine power generation from the perspective of efficiency optimisation. We re-adjust the reference current of each parallel generator to transform the working point of each generator and implement the efficiency optimisation of parallel system. The performance of the proposed control method is evaluated in detail by the simulation and experiment, and comparison with traditional CSC is carried out as well.

    Opis:
    In recent years, many studies have attempted to use deep learning for moving object detection. Some research also combines object detection methods with traditional background modeling. However, this approach may run into some problems with parameter settings and weight imbalances. In order to solve the aforementioned problems, this paper proposes a new way to combine ViBe and Faster-RCNN for moving object detection. To be more specific, our approach is to confine the candidate boxes to only retain the area containing moving objects through traditional background modeling. Furthermore, in order to make the detection able to more accurately filter out the static object, the probability of each region proposal then being retained. In this paper, we compare four famous methods, namely GMM and ViBe for the traditional methods, and DeepBS and SFEN for the deep learning-based methods. The result of the experiment shows that the proposed method has the best overall performance score among all methods. The proposed method is also robust to the dynamic background and environmental changes and is able to separate stationary objects from moving objects. Especially the overall F-measure with the CDNET 2014 dataset (like in the dynamic background and intermittent object motion cases) was 0,8572.

    Opis:
    The rapid development of digital products brings security issues. Digital watermarking technology is an important means to handle these problems. To enhance the imperceptibility of watermark and locate the possible tampering as well, a digital watermarking scheme based on curvelet transform is presented by combining with multiple chaotic maps. The host image is decomposed into three parts, i.e., coarse layer, detail layer and fine layer, with curvelet transform, and a robust watermark is embedded into the coarse layer for copyright protection of digital products. In addition, an authentication watermark is embedded into the fine layer to detect and locate the illegal changes. Simulation results show that the proposed digital watermarking scheme possesses acceptable robustness and security.

    Opis:
    The study is trying to use ATS (Affective Tutoring System) with emotional calculating technology in the activity of the shell education program. The result is used to study the academic achievement of students with different cognitive styles and system usability. There were 61 fifth-grade children from two different classes participating in this experiment. Every child had to do GEFT (Group Figure-Embedded Test) and academic achievement pre-test before they started the ATS. Then students engaged in ATS learning. Academic achievement post-test was done and the System Usability Scale for Learning Questionnaire after they finished the ATS. The experiment yielded the following results: (1) Learning with ATS not only can give learners an excellent feeling of system usability, but also help learners to promote academic achievement more effectively. (2) According to the system usability and academic achievement, the Field-independent learners were acting better than the Field-dependent learners.

    Opis:
    Living observation and silver impregnation methods were used to investigate the morphology and infraciliature of three Frontonia ciliates (F. guangdongensis spec. nov., F. ocularis Bullington, 1939 and F. schaefferi Bullington, 1939) that were isolated from coastal waters of the South China Sea. Frontonia guangdongensis spec. nov. may be recognized by the combination of the following characteristics: cells about 160 × 35 μm in vivo; elongated body with right margin depressed in anterior third; length to width ratio 4:1 to 5:1; three or four vestibular and four or five postoral kineties; peniculi 1 and 2 each with four rows of kineties, peniculus 3 with two rows; one contractile vacuole in mid-body region right of cell median; brackish water habitat. A key based on morphological data for fourteen marine or brackish water Frontonia species found in China is also provided. In addition, the small subunit (SSU) rDNA gene was sequenced for F. ocularis Bullington, 1939. Our phylogenetic analyses support the contention that the genus Frontonia is not monophyletic.

    Opis:
    Peptidylarginine deiminase (PAD) catalyzes the post-translational modification of protein through the conversion of arginine to citrulline in the presence of calcium ions. Human, similar to rodents, has four isoforms of PAD (type I, II, III and IV/V), each of which is distinct in substrate specificity and tissue specific expression. In our large-scale sequencing project, we identified a new human PAD cDNA from a human fetal brain cDNA library. The putative protein encoded by this cDNA is designated hPADVI. Expression analysis of hPADVI showed that it is mainly expressed in adult human ovary and peripheral blood leukocytes. We conclude that hPADVI may be orthologous to mouse ePAD, basing on sequence comparison, chromosome localization and exon-intron structure analysis. PAD-mediated deimination of epithelial cell keratin resulting in cytoskeletal remodeling suggests a possible role for hPADVI in cytoskeletal reorganization in the egg and in early embryo development. This study describes a new important member of the human PAD family.
