Background: Workforce health is one of the primary and most challenging issues, particularly in industrialized countries. This article aims at modeling the major factors affecting accidents in the workplace, including general health, work-family conflict, effort-reward imbalance, and internal and external locus of control. Methods: A cross-sectional study was conducted in Esfahan Steel Company in Iran. A total of 450 participants were divided into two groups-control and case-and the questionnaires were distributed among them. Data were collected through a 7-part questionnaire. Finally, the results were analyzed using SPSS 22.0 and Amos software. Results: All the studied variables had a significant relationship with the accident proneness. In the case group, general health with a coefficient of -0.37, worke-family conflict with 0.10, effort-reward imbalance with 0.10, internal locus of control with -0.07, and external locus of control with 0.40 had a direct effect on occupational stress. Occupational stress also had a positive direct effect on accident proneness with a coefficient of 0.47. In addition, fitness indices of control group showed general health (-0.35), worke-family conflict (0.36), effort-reward imbalance (0.13), internal locus of control (-0.15), and external locus of control (0.12) have a direct effect on occupational stress. Besides, occupational stress with a coefficient of 0.09 had a direct effect on accident proneness. Conclusion: It can be concluded that although previous studies and the present study showed the effect of stress on accident and accident proneness, some hidden and external factors such as work-family conflict, effort-reward imbalance, and external locus of control that affect stress should also be considered. It helps industries face less occupational stress and, consequently, less occurrence rates of accidents.

본 연구는 영유아 손자녀를 공동 양육하는 조모를 대상으로 기존의 조모들이 경험하는 스트레스나 부담감 중심의 시각에서 벗어나 조모들이 양육과정에서 획득하는 긍정적 측면에 주목하여 양육보상감을 검토하고 이에 대한 예측요인을 파악하는데 목적이 있다. 연구대상은 서울과 경기지역, 6대 광역시에 거주하며 만 6세 이하 손자녀를 양육하고 있는 조모 373명이며, 설문조사를 통해 수집된 자료를 위계적 회귀분석을 통해 분석하였다. 연구결과, 첫째 조모들은 양육과정에서 스트레스뿐만 아니라 중간이상의 보상감을 경험하고 있는 것으로 나타났다. 둘째, 조모의 양육보상감에 대한 영향요인으로 조부모로서의 의미인식과 성인자녀와의 관계, 경제적 수준이 주요 예측변인으로 나타났다. 이러한 연구결과를 토대로 맞벌이 가정에서 취업모를 대신해 손자녀를 돌보는 조모의 양육보상감을 증진하기 위한 중재적 개입의 필요성과 노년기 양육자를 위한 실천적 정책적 함의를 제시하였다.

본 연구는 신임해양경찰공무원을 대상으로 성격과 보상이 PSM에 영향을 미치는가에 대하여 연구한 결과 첫째, 성격 요인의 하위변인 중 신경성은 PSM의 하위변인인 공공정책 호감도와 공익몰입, 동정심에 영향을 미쳤다. 또한, 성격 요인의 하위요인 중 외향성 요인은 PSM의 하위변인 중 자기희생에만 영향을 미쳤다. 둘째, 보상 요인은 대부분 PSM에 영향을 미치지 않는 것으로 나타났고 이중 내적 보상은 PSM 하위변인 중 동정심에 영향을 미치는 것으로 분석되었다. 이러한 연구를 기반으로 성격 요인이 공공봉사 동기에 영향을 미치는 요인임이 확인된 결과 채용에서 반영할 수 있는 제도적인 개선이 필요하며 보상과 공공봉사 동기와의 관계를 검증하기 위한 연구의 필요성이 제기된다.

The reinforcement learning algorithm has proven its potential in solving sequential decision-making problems under uncertainties, such as finding paths to route data packets in wireless sensor networks. With reinforcement learning, the computation of the optimum path requires careful definition of the so-called reward function, which is defined as a linear function that aggregates multiple objective functions into a single objective to compute a numerical value (reward) to be maximized. In a typical defined linear reward function, the multiple objectives to be optimized are integrated in the form of a weighted sum with fixed weighting factors for all learning agents. This study proposes a reinforcement learning -based routing protocol for wireless sensor network, where different learning agents prioritize different objective goals by assigning weighting factors to the aggregated objectives of the reward function. We assign appropriate weighting factors to the objectives in the reward function of a sensor node according to its hop-count distance to the sink node. We expect this approach to enhance the effectiveness of multi-objective reinforcement learning for wireless sensor networks with a balanced trade-off among competing parameters. Furthermore, we propose SDN (Software Defined Networks) architecture with multiple controllers for constant network monitoring to allow learning agents to adapt according to the dynamics of the network conditions. Simulation results show that our proposed scheme enhances the performance of wireless sensor network under varied conditions, such as the node density and traffic intensity, with a good trade-off among competing performance metrics.

The subjects of the research were 275 aged care nurses working in Gyeonggi regions. The analysis result showed: job satisfaction in overall situation was 2.87 on a 5 point scale, indicating the level of job satisfaction was lower than average: the quality of life was 2.97, as with job satisfaction, also low. On the other hand, the research outcomes to discern if it affects the lower level of the quality of life, it was found that variables affecting psychological health include job, pay, co-workers, organization, changing an occupation/job; Social environment include job, pay, and promotion (reward), The maintenance of social relations, pay, promotion(reward) and co-workers, changing an occupation/job; variables affecting physical health include job, pay, promotion(reward), changing an occupation/job; The research outcomes confirm that the job satisfaction of aged visit care workers is an important factor affecting their quality of life.

To obtain realistic performance measures for wireless networks, one should consider changes in performance due to failure related behavior. In performability analysis, simultaneous consideration is given to both pure performance and performance with failure measures. SRN is an extension of stochastic Petri nets and provides compact modeling facilities for system analysis. In this paper, a new methodology to model and analyze performability based on stochastic reward nets (SRN) is presented. Composite performance and availability SRN models for wireless handoff schemes are developed and then these models are decomposed hierarchically. The SRN models can yield measures of interest such as blocking and dropping probabilities. These measures are expressed in terms of the expected values of reward rate functions for SRNs. Numerical results show the accuracy of the hierarchical model. The key contribution of this paper constitutes the Petri nets modeling techniques instead of complicate numerical analysis of Markov chains and easy way of performance analysis for channel allocation under SRN reward concepts.

Today's customer demands in supply chains tend to change quickly, variously even in a short time Interval. The uncertainties of customer demands make it difficult for supply chains to achieve efficient inventory replenishment, resulting in loosing sales opportunity or keeping excessive chain wide inventories. Un this paper, we propose an adaptive vendor managed inventory (VMI) model for a two-echelon supply chain with non-stationary customer demands using the action-reward learning method. The Purpose of this model is to decrease the inventory cost adaptively. The control Parameter, a compensation factor, is designed to adaptively change as customer demand pattern changes. A simulation-based experiment was performed to compare the performance of the adaptive VMI model.

The objective of this study is to select reward measure of improved business results. Grain sharing is defined as a compensation system that is designed to provide for variable compensation and to support an employee involvement process by rewarding the members of a group or organization for improvements in organizational performance. Gains, as measured by a predetermined formula, are shared with all eligible employees, typically through the payment of cash bonuses. Generally sales, profit, value-added, cost reduction portion and otherthings have been used as gains, otherwise improved business results, without any proof which is correlated to productivity improvement. This paper suggests which business result is fit reward measure for each business types and sizes.
