This paper refers to the issues related to safety of military wheeled vehicles. The paper contains a reference analysis of research studies conducted with military wheeled vehicles. Experimental and simulation research results, contained in this publication, constitute the basis for the analyses performed. The issues touched upon here are closely related to vehicles safety, which is reflected in the title of the paper. The analysis results may be useful for armed forces and the arms industry. Measurable effects result in increased safety of a vehicle, thus leading to a reduced risk of road accidents, reduced costs of building applications for military wheeled vehicles, lowered costs of making any possible changes in serial vehicles, and an acquisition of optimal structural designs in terms of safety for the Polish Armed Forces.

The Impact

Relevance of the article is based on participation of armed forces in various operations and exercises, where reliability of machinery is one of the most important factors. Transportation of soldiers as well as completion of variety of tasks is ensured by properly functioning technical equipment. Reliability of military vehicles – armoured SISU E13TP Finnish built and HMMWV M1025 USA built were selected as the object of the article. Impact of climatic conditions on reliability of the vehicles exploited in southwestern part of the Atlantic continental forest area is researched by a case study of the vehicles exploitation under conditions of the climate of Lithuania. Reliability of military vehicles depends on a number of factors such as properties of the vehicles and external conditions of their operation. Their systems and mechanisms are influenced by a number of factors that cause different failures. Climatic conditions represent one of the factors of operating load which is directly dependent on the climate zone. Therefore, assessment of the reliability is started with the analysis of climatic factors affecting operating conditions of the vehicles. Relationship between the impact of climatic factors and failure flow of the vehicles is presented and discussed.

The growing practice of returning individual results to research participants has revealed a variety of interpretations of the multiple and sometimes conflicting duties that researchers may owe to participants. One particularly difficult question is the nature and extent of a researcher’s duty to facilitate a participant’s follow-up clinical care by placing research results in the participant’s medical record. The question is especially difficult in the context of genomic research. Some recent genomic research studies — enrolling patients as participants — boldly address the question with protocols dictating that researchers place research results directly into study participants’ existing medical records, without participant consent. Such privileging of researcher judgment over participant choice may be motivated by a desire to discharge a duty that researchers perceive themselves as owing to participants. However, the underlying ethical, professional, legal, and regulatory duties that would compel or justify this action have not been fully explored.

The numerical model of top coal drawing in gently inclined seam is built based on PFC2d software. By comparing with the theory of drawn-body movement law, it can be obtained that the shape of top coal drawn-body accords with the theory of random medium movement. The research results show that the form of the shape equation of top coal drawn-body is uniform while the top coal caving angle is different. On the other hand, with the difference of top coal caving angle and drawing height, the shape of top coal drawn-body is differential at the meso scale, which depends on the parameters of the shape equation of top coal drawn-body.

In the paper, the model of estimating the loss of maintenance potential of high mobility wheeled vehicles within proving ground tests is presented. This problem is up-to-date, especially important for military vehicles. The authors have analysed the selected requirements directed to this class of vehicles. In the main body of the paper, some model that could be applied in on-line system of prognostic Health and Usage Monitoring System (pHUMS) was presented. This model can be used to analyse information about the maintenance process of vehicle before some maintenance decision would be made.

This research studies the associative meanings contained in the traditional medicinal fruits found in Indonesia. The object of research is not the benefits of the traditional medicinal fruits to cure any diseases. Instead, the research objective is the associative meanings contained in the traditional medicinal fruits. The perspective used in this research is the semantico-pragmatics theory. The research results show that the names of fruits found in various regions in Indonesia has associative meanings, such as iconic, collocative, affective, social, and reflective. The associative meanings are found in the traditional medicinal fruits, such as mengkudu, permot, tin, parijoto, leunca, kalaloyang, manggis, mahkota dewa, berunuk, cermai, delima, takokak, and jarak. This research contributes to the following purposes: (1) preserving the local wisdom values found in traditional medicinal fruits; (2) providing socio-cultural documentation of traditional medicinal fruits in various regions in Indonesia; (3) developing the study in the semantic-pragmatic field.

Intellectual capital is among the new, advanced management notions developed to overcome the inadequacy of previous administrations, to adapt to new situations and forge ahead of the competition. Intellectual capital means the information, experience and skills that offer advantage in competition and reveal the values existing within the structure of an enterprise. These values also exist in the relationship between  the enterprise and the environment  and  with the employees. Although some research studies on intellectual capital (IC) have been conducted, to date no research has been carried out on the effects of IC on qualitative and quantitative organizational performance. For this reason, IC and its effects on firm performance (both qualitative and quantitative) were evaluated in this study. Following the evaluation of the intellectual capital and its sub-elements, the differentiation of the sub-elements is made. Then the reliability and validity of these sub-factors are calculated. The intellectual capital model has been tested by the structural equality model (SEM).  According to research results, IC explains 92  per cent of a firm’s performance. The effect of IC on qualitative performance is 0,84, while on quantitative performance it is 0,72. RC impresses qualitative performance with coefficient 0,94, quantitative performance with coefficient 0,60; HC impresses qualitative performance with coefficient 0,92, quantitative performance with coefficient 0,54 less; SC impresses qualitative performance with coefficient 0,90, quantitative performance with coefficient 0,53. According to the results of the research, IC affects both the qualitative and the quantitative performance of firms by supplying extensive knowledge to the managers.

Road accidents are one of the basic road safety determinants. Most research covers large territorial areas. The results of such research do not take into account the differences between individual regions, which often leads to incorrect results and their interpretation. What makes it difficult to conduct analyses in a narrow territorial area is the small number of observations. The narrowing of the research area means that the number of accidents in time units is often very low. There are many zero observations in the data sets, which may affect the reliability of the research results. Such data are usually aggregated, which leads to information loss. The authors have therefore applied a model that addresses such problems. They proposed a method that does not require data aggregation and allows for the analysis of sets with an excess of zero observations. The presented model can be implemented in different territorial areas.
