Purpose: To investigate the work associated stress and nicotine dependence among law enforcement personnel in Mangalore, India. Materials and Methods: A cross-sectional questionnaire survey was conducted among law enforcement personnel in Mangalore, India. Demographic details, stress factors experienced at work and nicotine dependency were the variables studied. The extent of stress factors experienced at work was assessed using the Effort-Reward Imbalance scale (ERI). Nicotine dependence was measured using the Fagerstrom Test for Nicotine Dependence (FTND) and the Fagerstrom Test for Nicotine Dependence-Smokeless Tobacco (FTND-ST). Logistic regression was used for the statistical analysis. Results: Three hundred and four law enforcement personnel participated in the study, among whom 68 had the presence of one or more habits like tobacco smoking, tobacco chewing and alcohol use. The mean effort score was $15.8{\pm}4.10$ and the mean reward and mean overcommitment scores were $36.4{\pm}7.09$ and $17.8{\pm}5.32$ respectively. Effort/Reward ratio for the total participants was 1.0073 and for those with nicotine habit was 1.0850. Results of our study demonstrated no significant association between domains of ERI scale and presence of habits but work associated stress was associated with the presence of one or more habits. Compared to constables, head constables had 1.12 times higher risk of having a nicotine habit. Conclusions: Our study implies job designation is associated with nicotine habits. However, there was no association between work associated stress and nicotine dependence among law enforcement personnel in Mangalore.

This study purposes to analyze how the level of compensation system qualify(transparency, fairness, controllability) affects the satisfaction of employee concerned with compensation system and work efforts. To test above mentioned objectives, i conduct using the survey data directly survey and e-mail to the MBA students of university located In southeastern korea and analyze using the structural equation model. The results of this paper are as follows. First, the analysis results demonstrate a positive relationship between the level of compensation system qualify and the satisfaction of employee concerned with compensation system. Second, the level of compensation system quality positively affects employee' work efforts. Thirdly, the satisfaction of employee concerned with compensation system also positive effects on work effort. The above results mean that if the level of compensation system quality is higher, employee are satisfied with the compensation system, and increase the level of work effort.

Background: Patient safety and accurate implementation of medication orders are among the essential requirements of par nursing profession. In this regard, it is necessary to determine and prevent factors influencing medications errors. Although many studies have investigated this issue, the effects of psychosocial factors have not been examined thoroughly. Methods: The present study aimed at investigating the impact of psychosocial factors on nurses' medication errors by evaluating the balance between effort and reward. This cross-sectional descriptive study was conducted in public hospitals of Tehran in 2015. The population of this work consisted of 379 nurses. A multisection questionnaire was used for data collection. Results: In this research, 29% of participating nurses reported medication errors in 2015. Most frequent errors were related to wrong dosage, drug, and patient. There were significant relationships between medications errors and the stress of imbalance between effort and reward (p < 0.02) and job commitment and stress (p < 0.027). Conclusion: It seems that several factors play a role in the occurrence of medication errors, and psychosocial factors play a crucial and major role in this regard. Therefore, it is necessary to investigate these factors in more detail and take them into account in the hospital management.

Nowadays, the conflict of work and family has become a common problem in families due to the increase of working parents. But in Korea, there is a little supporting system which can help them work. So, this study showed the necessity of family-friendly Policy and families' demands to it. Many capitalist countries which have insufficient welfare system effort to integrating work and family by offering a family-friendly policy for working parents. So, policies for family and women have to be family friendly, and all of the corporation, community, school, and government have to support the working families.

Supply chain coordination plays a critical role in improving the enterprise performance and the competitive advantage of fresh e-commerce. This study explores the coordination problem of a two-echelon fresh produce e-commerce supply chain comprising a fresh e-commerce enterprise and a fresh supplier in a novel framework. In this framework, the fresh e-commerce sells fresh produce and provides promotion effort; meanwhile, the fresh supplier deliveries fresh produce and provides freshness-keeping effort. Specifically, the optimal decisions under centralized and decentralized decision-making are compared, and it is found that centralized decision-making is more profitable. Based on this work, we created a cost-sharing and revenue-sharing combination contract. This study demonstrates that this contract effectively coordinates the supply chain and makes both parties achieve Pareto optimization when the parameters meet certain conditions. Finally, the feasibility and validity of the contract are presented through a numerical example.

SM 프로젝트는 SI 프로젝트와 달리 고객의 요청 사항(CSR)이 있을 때 마다 개발 계획을 세우고 관리를 하여야 하며 동시에 고객의 개발 요청 내용 외에도 운영업무에 대한 계획도 같이 세워 져야 한다. 하지만 대부분의 SM 프로젝트에서는 한 두 사람의 경험이나 판단으로 계획이 작성, 할당되며 운영업무에 대한 계획의 정확도도 떨어져 업무 load balancing 이 잘 되지 않는다. 본 논문에서는 이러한 문제 해결을 위해 효과적인 SM 프로젝트에서의 EFFROT ESTIMATION 프로세스를 제안하여 업무 load balancing 을 이루는 방안을 제시하고자 한다.

This paper gives an overview of the CBUF project. The work described is the collective effort of 11 CBUF partners, laboratories, universities, industries, in 8 countries. It became possible to do this research thanks to the European Commission interest in the burning behaviour of upholstered furniture and their willingness to sponsor this large effort. The opportunity to work with the many of the most prominent fire researchers and furniture experts have been extremely rewarding. All the expertise of these scientists have resulted in a lot of research results that are presented. The article only gives the main findings and conclusions of the project, namely the presentation of the fire safety design procedure of the CBUF project. Other articles will deal with specific modelling topics and an extensive description of the project can be found in the final CBUF report EUR 16477 EN.

Accurate software effort estimation has always been a challenge for the software industrial and academic software engineering communities. Many studies have focused on effort estimation methods to improve the estimation accuracy of software effort. Although data quality is one of important factors for accurate effort estimation, most of the work has not considered it. In this paper, we investigate the influence of outlier elimination on the accuracy of software effort estimation through empirical studies applying two outlier elimination methods(Least trimmed square regression and K-means clustering) and three effort estimation methods(Least squares regression, Neural network and Bayesian network) associatively. The empirical studies are performed using two industry data sets(the ISBSG Release 9 and the Bank data set which consists of the project data collected from a bank in Korea) with or without outlier elimination.

Recently, workers are interested in work-life balance. However, most dual- income couples do not make the effort to achieve work-life balance in their everyday life compared with many workplaces that make various family-friendly policies available to them. Therefore, this study aims to suggest the necessity and process of work-life balance through career management over one's lifespan. The needs and resources of families are not the same during every stage of the family life cycle. Thus, dual-income couples should aim to invest in career management which includes balancing their work and their family when considering their future career and life. Additionally, they should try to match the needs and resources of both their work and their family by using family resources, workplace policies, and community networks.
