Knowledge creation has become one of core assets for companies' survival and success, companies are putting their effort to find the way to stimulate sharing knowledge among their workers. In this vein, the purpose of this study was to examine the effect of supervisor support and co-worker support on knowledge sharing and the mediating effects of work engagement. 328 employees from varity of organizations located in Korea particiapted for questionnaire survey. Structural equation modeling was used to analyze the data. The result has shown that the static correlation exists between supervisor support, co-worker support and work engagement. Co-worker support had positive influences on knowledge sharing intention. However, supervisor support did not have any influence on knowledge sharing intention. There was a mediate effect of work engagement between both of supervisor and co-worker support and knowledge sharing intention. The study implies that co-worker support is important in order to improve organizational learning and work engagement as a strategy to enhance organizational performance.

Objectives: The purpose of this study is to calculate the worker-DNEL (Derived No Effect Level) values using the REACH guidance and compare the calculated DNELs with existing Korea occupational exposure limits (KOELs) for evaluation of the applicability of the worker-DNELs as provisional occupational exposure limits for chemicals that are not established KOELs in the workplace. Methods: The worker-DNELs for 46 chemicals among 113 hazardous substance requiring management were calculated using the REACH guidance, and a paired t-test was performed to see if there is any statistical difference between two lists (worker-DNELs vs KOELs). The ratios of KOELs over worker-DNELs were also calculated to compare the overall levels of two lists using the geometric means method. Results: The calculated worker-DNELs for 46 chemicals ranged from 0.001 to $329mg/m^3$ (GM= 6.9, GSD = 10.8), and appeared to be a significant difference between the worker-DNELs and the KOELs (p < 0.01). In addition, the ratios of KOELs over worker-DNELs ranged from 0.3 to 394 times (GM = 10.2, GSD = 3.9), indicating that the worker-DNELs were, on average, 27 times lower than the KOELs. Conclusions: Therefore, the study results show that the calculated worker-DNELs can be applied and used as provisional occupational exposure limits in the workplace in order to reduce worker exposures to chemicals and health risks, and manage potential worker exposures based on the precautionary principle through comprehensive chemical risk assessment.

The shipbuilding and offshore industry is a large and complex assembly industry, which causes many safety accidents. The major accidents in the shipbuilding and offshore industry workplaces are stenosis, falling objects, dust, fire, explosions, and gas poisoning. The accident by worker in this industry mainly has three factors: frequent movement, narrow work space, and increased use of subcontractors. To control these factors, it is necessary to monitor the worker's location and work status. In this paper, a worker location monitoring system using inaudible sound wave was designd that can be used in environments with many metal barriers. The process included deriving stakeholder requirements, transforming to system requirements, designing system architecture, and developing prototype. The prototype was validated by third-party testing agency. As a result, it satisfied the designed performance and verified its feasibility.

Knowledge sharing has many benefits; however, employees are generally reluctant to share their knowledge with co-workers. This reluctance can be attributed to the facts that sharing knowledge involves the threat of losing personal competitiveness and the codification of knowledge for sharing requires additional effort. This study explains why employees engage in knowledge sharing despite the threat and cost of sharing knowledge. Specifically, it examines the effects of the quality of co-worker exchange (CWX) on knowledge sharing and the moderating effect of learning goal orientation on the relationship between CWX and knowledge sharing. Data from 186 individuals indicate that there is a positive relationship between CWX and knowledge sharing, and that this relationship is strengthened when learning goal orientation is low rather than when it is high. The theoretical and practical implications of the findings are also discussed.

This study was conducted to identify the attitude of ethical dilemmas in hospital nurses. Ethical dilemmas were categorized into four areas : human life area, clients area, nursing practice area, and nurses-co-worker area. 354 nurses working in clinical settings were selected in Seoul and Kangwon area. Data were gathered from 26, June to 10, July, 1994 by structured guestionnaires. Descriptive statistics were employed to analyze the data. The results obtained from data were as follows : 1) In human life area mean score was 3.03. This area showed remarkabale individual differences between utilitarian and deontological position. 2) In clients area mean score was 3.94. It means that nurses tend to take a deontological position. 3) In nursing practice area mean score was 3.41. It means that nurses tend to take a slightly deontological position. 4) In nurses-co-worker area mean score was 3.88. It means that nurses tend to take a deontological position. To conclude, clinents area, nursing practice area, and nurses-co-worker area taken deontological position. Most nurse's primary concern was the 'welfare of the patients' which is to fundamental ethical professional practice. But nurses experienced more ethical dilemmas in human life area than others. Therefore, nurses should be prepared to make in-dependent decision that based on bio-ethics and professional ethics.
