Opis:
The high rates of casualties in bulk carrier shipping have attracted a worldwide concern for safety and regulatory control from numerous governmental and private agencies. Between 2011 and 2020, a total number of 34 bulk carriers’ ships has been identify as total loos, resulting to the death of 128 seafarers. In this study, the statistically analysis of bulk carrier accident occurring from 2011 to 2020, in terms of their frequency, types of accident, locations of incidents and the factors that influence their occurrence has been reviewed. This study will contribute to decision-making and guidance on rational safety resource allocation that will help reduce the high casualty rates in bulk carrier.

Opis:
la partecipazione di veicoli a motore a incidenti stradali comporta la necessità di ripararli o di ritirarli dal servizio. Tali attività sono di norma precedute da una procedura di liquidazione condotta dall’impresa di assicurazione, che nel corso della quale può dichiarare il cosiddetto danno totale. Tuttavia, l’inutilità economica della riparazione spesso non è legata al riconoscimento del veicolo come rifiuto e al suo ritiro dall’utilizzo. Nel definire il concetto di danno totale, l’autore discute gli effetti sul riconoscimento del veicolo come rifiuto nel contesto della sua vendita, riparazione, importazione e ritiro dall’uso.

Opis:
Objective: To develop a method, based on Pareto principles, for increasing resource management effectiveness with prediction and minimisation of losses arising from emergency situations, both industrial and natural within the project-based organisation structure of the civil protection system. Methods: Theoretical research of an effective management process, with the aid of Pareto distribution, was applied to project organisational structures through the Office of Civil Protection. Current project management tools such as: PMBOK, P2M, PRINCE2, ICB, etc. provided a basis for scientific research. During the research process various methods were applied such as: systems theory, systems analysis, statistical analysis, cognitive analysis theory, mathematical modelling, information technology and management. Results: Presentation of theoretical and experimental data allowed for the calculation of losses during emergency situations. These were determined with the aid of Pareto distributions and statistical methods, with a focus on minimising and estimating losses more accurately. The developed technique allows for the control of singular as well as global losses, at all phases as well as levels of management within the project office, simultaneously ensuring the mitigation of losses and attainment of a high level of functional effectiveness of the civil protection system. The basis for the developed technique was a mathematical description of characteristic indicators and maximum as well as total losses for the Pareto distribution. This approach revealed credible data which will help to increase the effectiveness of performance in a unified system of civil protection. Results allow for better management decisions, improved predictions and minimisation of losses arising from environmental disasters. Conclusions: Results from research allowed, on the basis of long term statistical data, to achieve a high degree of convergence. The developed technique, using Pareto distributions, demonstrated that its application to resource management in the civil protection system leads to minimisation of losses during emergency situations and optimisation of the project management process, simultaneously making it possible to anticipate resource losses at all stages. Furthermore, research was harnessed to address current and applied research challenges, which impact on the improvement of project and programme management; optimal allocation of losses and creation of the most favourable conditions for the organisational management of a unified system of civil protection under the auspices of The Office of Civil Protection. The proposed method describes characteristic values of total and maximum losses, which may be used to obtain most accurate and relevant data, which in turn make it possible to minimise errors during management decision making, and significantly enhance the research base for projects and programme management methods . Obtained results will afford an opportunity to consider the unified system of civil protection in Ukraine in context of a project organisation structure.
Cel: Opracowanie metody, która opiera się na zasadzie Pareto w celu zwiększenia efektywności zarządzania zasobami przy prognozowaniu i minimalizacji strat wynikających z sytuacji nadzwyczajnych klęsk i katastrof spowodowanych przez człowieka w projektach, programach i portfelach w projektowej strukturze organizacyjnej systemu ochrony cywilnej. Metody: Badania teoretyczne procesu efektywnego zarządzania za pomocą rozkładu Pareto stosowanego w projektowych strukturach organizacyjnych biura ochrony ludności. Podstawą metodologii badań naukowych jest nowoczesne zarządzanie projektami, programami i portfelami projektów: PMBOK, P2M, PRINCE2, ICB, itp. Podczas badań stosowano metody: teorii systemów i analizy systemów, badania statystyczne, teorii analizy poznawczej, modelowanie matematyczne, informacje technologia oraz zarządzanie. Wyniki: Zaprezentowane dane teoretyczne i doświadczalne umożliwiły stworzenie na podstawie zasady Pareto i metod statystycznych uniwersalnej metodologii obliczania strat powstałych w sytuacjach kryzysowych w celu zapewnienia ich minimalizacji i bardziej dokładnej prognozy. Opracowana metoda pozwala na kontrolę zarówno pojedynczych jak i globalnych strat we wszystkich fazach i na wszystkich etapach zarządzania biurem projektów, programów i portfeli projektów, jednocześnie zapewniając minimalizację strat i wysoką efektywność funkcjonowania systemu ochrony cywilnej. Podstawą opracowanej techniki był matematyczny opis charakterystycznych wskaźników oraz maksymalnych i całkowitych strat dla rozkładu Pareto, dzięki któremu uzyskano wiarygodne dane zwiększające efektywność projektów, programów i portfeli w jednolitym systemie ochrony cywilnej. Uzyskane wyniki umożliwią podejmowanie lepszych decyzji w zakresie zarządzania, przewidywania i minimalizacji strat wynikających z klęsk żywiołowych. Wnioski: Wyniki tych badań pozwoliły na podstawie statystyk długoterminowych uzyskać wysokie wyniki konwergencji. Metoda opracowana z wykorzystaniem rozkładu Pareto wykazała, że stosowanie metodologii w zarządzaniu biurem projektów w systemie ochrony cywilnej stanowi proces minimalizacji strat w sytuacjach kryzysowych i optymalizacji zarządzania projektami, programami i portfelami projektów, jednocześnie zapewniając możliwość przewidzenia strat zasobów na wszystkich etapach projektów, programów i portfeli realizacji projektów. Ponadto, badania teoretyczne opierały się na realizacji bieżących i stosowanych problemów naukowych, które wpływają na poprawę zarządzania projektami i programami: optymalną alokację strat i tworzenie jak najkorzystniejszych warunków dla organizacyjnego zarządzania jednolitym systemem ochrony ludności za pośrednictwem Urzędu Ochrony Cywilnej. Proponowana metoda opisuje charakterystyczne wartości całkowitych i maksymalnych strat, dzięki którym możliwe będzie uzyskanie najbardziej dokładnych i aktualnych danych, które będą minimalizować błędy w podejmowaniu decyzji zarządczych, znacznie wzbogacą bazę naukową projektu i metodykę zarządzania programami. Uzyskane wyniki będą również okazją do rozważenia jednolitego systemu ochrony ludności Ukrainy jako projektowej struktury organizacyjnej.

Opis:
This paper focuses on determining the differences between economic value added (EVA), net operating profit after tax (NOPAT), earnings before interest and taxes (EBITDA), and net income or loss for non-financial business entities operating in the Republic of Croatia in the period 2002–2021. The main objective of this paper is to determine whether non-financial activities create economic value added, and rank them according to selected indicators based on EVA. Research results indicate that there were only 27 out of 309 cases where EVA was positive, indicating that only the information and communication sector generated, on average, positive EVA during this twenty-year period. Positive EVA was generated in certain years in companies conducting human health and social work activities, education, mining, and quarrying, as well as in wholesale and retail trade activities, but the average EVA for this twenty-year period in these sectors was negative. At the same time, net income was achieved in 246 cases, and NOPAT in 285. Meanwhile, EBITDA was positive in all cases, demonstrating an obvious discrepancy between EVA and other financial performance measures. Correlation analysis results indicate that there is a statistically significant moderate correlation between EVA and net income/loss, although the correlation is generally stronger between EVA and EBITDA-based indicators. According to research results, the answer to the question in the title of this paper is negative, emphasizing the possibilities of intensive introduction of EVA as a financial performance indicator.

Opis:
In the paper, we investigate queueing system M/G/∞ with non-homogeneous customers. By non-homogeneity we mean that each customer is characterized by some arbitrarily distributed random volume. The arriving customers appear according to a stationary Poisson process. Service time of a customer is proportional to his its volume. The system is unreliable, which means that all its servers can break simultaneously and then the repair period goes on for random time having an arbitrary distribution. During this period, customers present in the system and arriving to it are not served. Their service continues immediately after repair period termination. Time intervals of the system in good repair mode have an exponential distribution. For such system, we determine steady-state sojourn time and total volume of customers present in it distributions. We also estimate the loss probability for the similar system with limited total volume. An analysis of some special cases and some numerical examples are attached as well.

In the paper, we investigate multi-server closed queueing systems with identical servers and a finite number of terminals. Requests from each terminal are characterized by a random space requirement (volume), the request service time doesn’t depend on its volume and has an exponential distribution. The total requests capacity in the system is limited by a positive value (buffer space memory volume) V. For such systems, stationary requests number distribution and loss probability are determined. The analogous results for open multi-server systems are obtained as a limit case. Some numerical results are attached as well.

Opis:
Humiliating situations can occur both at the macro level (when dealing with specific social groups) and the micro level (when they appear in the relations of the individual with social environment). Humiliation always brings negative consequences, and is a source of suffering and shame. It also robs a man of dignity and violates his internal integrity. Ruthlessness of dehumanization mechanisms is present in thinking and action of a person who uses humiliation as a tool of influence and the way of achieving his own benefits. The victim of dependency and social inequality may take different strategies to cope with humiliation. This text is an attempt to search for the answers to the question about the causes and consequences of humiliation in interpersonal relations, both in a social ad individual context.

Opis:
This study was conducted to investigate the effects of pre-harvest Harpin treatments and post-harvest MAP treatments on fruit quality attributes and bioactive compounds of ‘0900 Ziraat’ cherry cultivar throughout cold storage and shelf life of the fruits. Weight loss and decay ratios were significantly reduced with Harpin and MAP treatments. In general, lower L* and chroma values were measured in Harpin-treated fruits. As compared to control fruits, higher firmness, titratable acidity and vitamin C contents were measured in MAP and Harpin + MAP treated fruits throughout the cold storage and shelf life. On the other hand, lower solible solids content (SSC) values were observed in the same treatments. At harvest and shelf life measurements, higher total monomeric anthocyanin (TMA) and total phenolics (TPs) were measured in Harpintreated fruits than in control fruits. Although lower anthocyanin contents were obtained from MAP-treated fruits throughout the cold storage, higher values were observed throughout shelf life. Throughout cold storage and shelf life, MAP-treated fruits had lower total phenolics and total antioxidant activity (according to FRAP and TEAC assay) values than the control and Harpin-treated fruits. It was concluded that Harpin and MAP treatments could be used reduce weight losses and decays throughout the cold storage.

Opis:
A queueing system of the M/G/n-type, n ≥ 1, with a bounded total volume is considered. It is assumed that the volumes of the arriving packets are generally distributed random variables. Moreover, the AQM-type mechanism is used to control the actual buffer state: each of the arriving packets is dropped with a probability depending on its volume and the occupied volume of the system at the pre-arrival epoch. The explicit formulae for the stationary queue-size distribution and the loss probability are found. Numerical examples illustrating theoretical formulae are given as well.

The effects of combined aminoethoxyvinylglycine (AVG) and modified atmosphere packaging (MAP) treatments on quality attributes of ‘0900 Ziraat’ sweet cherry fruit during the cold storage and shelf life were investigated in this study. Significantly lower weight loss and decay ratios were observed in all treatments throughout the cold storage period as compared to the control. A similar case was also observed referring to the shelf life. MAP treatments were found to be more effective in retarding the weight loss and decay ratio. Higher hue angle values were measured from AVG-treated fruit at harvest. Similarly, hue angle of AVG and MAP-treated fruit were also higher than for the control in all periods of cold storage and on the 7th and 21st day of shelf life. AVG-treated fruit had higher firmness values than the control at harvest. However, higher firmness values were measured from MAP-treated fruit during the cold storage and shelf life. At the end of cold storage, lower SSC and higher titratable acidity values were observed in AVG and MAP-treated fruit than in the control. AVG + MAP treatments yielded significantly higher vitamin C, total phenolics and antioxidant activity values than the control. Contrarily, the control fruit had significantly higher total monomeric anthocyanin than the other treatments. Based on current findings, it was concluded that combined AVG + MAP treatments could be used as a beneficial tool to maintain the quality of sweet cherry fruit throughout the cold storage and shelf life.

Measurement of value creation is not simple. The increase in shareholders value will not necessarily mean its creation, because the creation of shareholders value can be defined more or less rigorously. The article focuses attention on market metrics of value: market value added (MVA) and total shareholder return (TSR), as measures the most directly related to the concept of creation value for shareholders. It also describes a distinction between the concept of value creation and value creation for shareholders, discussing their excess forms as well.

Opis:
In the paper, we investigate a single-server queueing system with unlimited memory space and non-homogeneous customers (calls) of the two following types: 1) external customers that are served by the system under consideration, 2) internal customers that arrive and interrupt the service process only when an external customer is being served. The external customers appear according to a stationary Poisson process. Customers of each of the above-mentioned types are characterized by some random volume. The customer service time depends arbitrarily on its volume. Two schemes of customer service organization are analyzed. The non-stationary and stationary distributions of the total volume of customers present in the system are determined in terms of Laplace and Laplace-Stieltjes transforms. The stationary first and second moments of total customers volume are also calculated. The obtained results are used to approximate loss characteristics in analogous systems with limited buffer space. Numerical examples illustrating theoretical results are attached as well.

Opis:
Purpose: The number of people suffering from Degenerative Disc Disease (DDD) is increasing. The disease causes heavy pain and restrict a number of day-to-day life activities. In extreme cases, the degraded disc is removed under total disc replacement which is usually made up of Ultra-High Molecular Weight Polyethylene (UHMWPE). The material has astounding biocompatible characteristics mechanical properties and wear resistance. However, these characteristics are insufficient in arthroplasty application. Therefore, research investigations are ongoing to improve tribological properties through reinforcement that may result in a composite material of UHMWPE. Thus the current study is aimed at reinforcing UHMWPE with short fibres of polyesters to enhance the tribological properties and surface characteristic so as to improve wear resistance and nourish the fibroblast cells on synthetic disc. Design/methodology/approach: The researcher prepared UHMWPE composite material, reinforced with different weight fractions of short polyester fibres (2, 4, 6, 8 and 10% following hot press method. Further pin-on-disc device was used to study the tribological properties (coefficient of friction and volume of wear). The study tested surface roughness and surface characteristics by atomic force microscopy (AFM) device, hardness by shore D device, contact angle to study the effect of polyester short fibres on wettability of UHMWPE surface and tested the thermal properties and crystalline degree using Differential Scanning Calorimetry measurement (DSC) device. Findings: The results infer that the wear resistance got improved when using 2% w.t polyester though it got decreased initially. However, the value was still more than neat UHMWPE. There was a decrease observed in coefficient of friction, but after 4 w.t% polyester, the coefficient of friction got increased due to increasing percentage of fibres which make it harder and stiff compared to UHMWPE. There was a decline observed in surface roughness due to alignment of the fibres with smooth surface. The contact angle got increased in a moderate range while the roughness enhanced the growth of fibroblast cell. The hardness of composite material got increased, because the fibres turned stiffer and harder than the matrix. DSC results infer the improvements in thermal stability due to high thermal properties of polyester fibres compared to UHMWPE. The degree of crystallinity got increased which in turn enhanced wear resistance, especially at 6 w.t % polyester fibres. There was a mild increase observed in density since the density of polyester is higher than polymer. Research limitations/implications: The major challenge was the dispersion of fibres. Uniform distribution of fibres within the matrix (UHMWPE) was achieved through two steps of mixing processes such as mechanical mixture and twin extruder. In future studies, fatigue tests must be conducted to study the behaviour of prepared composite materials under fatigue cycle. Practical implications: A significant objective is how to connect among different properties to obtain good improvement in tribological and surface properties so as to enhance wear resistance and growth of fibrolase cells. Originality/value: In this study, polymeric short fibres were used as reinforcement with polymeric matrix to enhance the wettability of fibres with matrix. In this way, the bonding among them got increased which supports the tribological, surface, and crystalline behaviour.
