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.

본 연구의 목적은 화폐적 보상, 비화폐적 보상을 포함하는 보상시스템의 질(보상시스템의 투명성, 공정성, 자기통제력)이 보상시스템에 대한 종업원 만족도에 미치는 영향과 나아가 개인의 노력투입에 미치는 영향을 실증적으로 검증하는데 있다. 동남권 소재 경영대학원에 재학중인 학생들을 대상으로 설문조사를 통해 자료를 수집하였고, 구조방정식 모형을 이용하여 분석한 결과를 종합하면 다음과 같다. 첫째, 종업원의 보상시스템 질(투명성, 공정성, 자기통제력)과 종업원의 보상시스템 만족도, 노력투입 간에 양(+)의 관련성을 보이는 것으로 나타났다. 둘째, 종업원의 보상시스템에 대한 만족도가 증가할수록 개개인의 노력투입 또한 증대되는 것으로 나타났다. 이상의 결과들은 보상시스템이 보다 투명하게 운영되고, 분배, 절차적 공정성을 갖추고 있으며, 보상시스템에 대한 종업원의 통제가능성이 보다 높을 경우 종업원의 보상시스템에 대한 만족도를 높일 수 있으며 바람직한 노력투입을 유도할 수 있다는 것을 의미한다.

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.

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.

정확한 소프트웨어 공수 예측은 소프트웨어 관련 여러 커뮤니티들에서 예전부터 항상 이슈가 되어 왔다. 소프트웨어 공수 예측의 정확도를 향상시키기 위해 지금까지 많은 연구들에서는 데이타 품질이 공수 예측에 중요한 요소들 중 하나임에도 불구하고 이것에 대한 고려 없이 공수 예측 기법들에만 초점을 맞추어 왔다. 본 연구에서는 소프웨어어 공수 예측 기법과 이상치 제거 기법들 사이의 영향 관계를 공수 예측 정확도의 관점에서 실험적으로 살펴본다. 두 개의 프로젝트 데이타들(ISBSG와 국내의 한 금융 조직으로부터 수집된 데이타)에 대해 일반적으로 많이 사용되는 세 가지 공수 예측 기법(최소제곱법, 신경망 네트워크, 그리고 베이지안 네트워크)과 두 가지 이상치 제거 기법(최소절사제곱법과 K-means 클러스터링)을 적용시켜 결과들을 서로 비교해 보고 이상치 제거 기법을 적용하지 않은 결과와도 비교해 본다.

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.
