Objectives: This study was focused on the influence of chronic aircraft noise exposure on children's continuous performance, intelligence and reading skill. Methods: We enrolled 586 children in 4-6th grade of 7 primary schools near air base in Korea. Continuous performance was measured using the computerized ADS program. We analyzed 477-512 children on the visual continuous performance test, auditory continuous performance test, intelligence test, and reading and the vocabulary test. Intelligence was measured using vocabulary, digit span, block design, and digit symbol tests of K-WISC-III. Results: The commission error and variability deviation of auditory continuous performance test and reading test were significantly higher among children in schools with the helicopter noise and the fighting plane noise compared to children in the low noised schools. Conclusion: There was a possibility that chronic aircraft noise exposure was associated with impairment of the school performance. The result of our study also shows chronic aircraft noise was associated with reading ability.

The purpose of this study is to empirically verify whether there are differences according to group characteristics in the effect of job characteristic requirements on practice performance in university long-term on-site training. Specifically, the relationship between job characteristics (job scope, job content, coaching, benefits), practical satisfaction, and occupational competencies was examined according to the group characteristics (gender types, major types, corporation types). For this purpose, the survey data were collected and analyzed for 752 students who participated in K university long-term on-site training. As a result of the analysis, first, it was found that the job characteristics (job scope job content, coaching, benefits) had structural relationship affecting occupational competence through mediation of practice satisfaction. Second, As for the differences according to the group characteristics, there were differences in the relations. Based on the result, theoretical and practical implications and follow-up studies were proposed.

Purpose: This study was designed to investigate nursing students' exposure experience to infectious diseases and their knowledge and performance for the nosocomial infection control. Method: The data was obtained from 292 nursing students having clinical experience at two university hospitals in Seoul from November 2005 to February 2006. Specific questionnaire was constructed and used for this study. The obtained data was analyzed by using the SPSS window program. Result: The results were as follow : 1. Among the evaluation scores of knowledge for the nosocomial infection control, the score of sterilization and the score of the intravenous therapy management were low(.14). 2. Among the evaluation scores of performance for the nosocomial infection control, the score of hand washing is low(1.63). 3. 86.3 percent of the nursing students had exposure experience to infectious disease. Many of them did not use the protective equipments in clinical experience nor took any treatment after the exposure to infectious diseases. Conclusion: Based on these results, we suggest that the programs for the nosocomial infection control should be developed for nursing students. It is also suggested that nursing students should be educated before their clinical experience to keep protected from the infection. In particular, the hand washing, sterilization and intravenous therapy management should be emphasized in the educational programs.

Studies have claimed that ESE (Early Streamer Emission) air terminals offer a vastly increased zone of protection over that of traditional lightning rods (Franklin rods) by causing the emission of an upward streamer/leader: The upward streamer/leader will propagate towards the tip of the downward leader at an early stage in the attachment process.. This paper shows the results of a performance evaluation test of a particular type of the ESE air terminal (called "ElecHippo") with a simple rod tested at the Korea Electrotechnology Research Institute (KERI). The corona emission current of the ElecHippo made by Yong-Jin Enterprise Corp. has also been measured at the Occupational Safety & Health Research Institute (OSHRI). The results show that the ElecHippo meets the French standard of NFC 17-102-1995. The results also verify the ESE performance by measuring the ion emission current generated in the discharge electrode gap as a function of the capacitance and inductance of the equipped devices. Finally, we propose a new method for grounding the system to reduce the lightning damage by combining the ESE air terminal, the early discharge earth plate, the lightning strike recorder and the surge protection device.

Background: Traditional safety concept, which is called Safety-I, and its relevant methods and models have much contributed toward enhancing the safety of industrial systems. However, they have proved insufficient to be applied to complex socio-technical systems. As an alternative, Safety-II and resilience engineering have emerged and gained much attention for the last two decades. However, it seems that safety professionals have still difficulty understanding their fundamental concepts and methods. Accordingly, it is necessary to offer an introductory guide to them that helps safety professionals grasp them correctly in consideration of their current practices. Methods: This article firstly explains the limitations of Safety-I and how Safety-II can resolve them from the four points of view. Next, the core concepts of resilience engineering and Functional Resonance Analysis Method are described. Results: Workers' performance adjustment and performance variability due to it should be the basis for understanding human-related accidents in socio-technical systems. It should be acknowledged that successful and failed work performance have the same causes. However, they are not well considered in the traditional safety concept; in contrast, Safety-II and resilience engineering have conceptual bases and practical approaches to reflect them systematically. Conclusion: It is necessary to move from a find-and-fix and reactive approach to a proactive approach to safety management. Safety-II and resilience engineering give a set of useful concepts and methods for proactive safety management. However, if necessary, Safety-I methods need to be properly used for situations where they can still be useful as well.

We could not find researches for relationship between safety performance and business performance in comparison with other research areas. Then in this paper we suggest the hypotheses which can systematically explain the relationship between safety performance and business performance and analyze the effects of safety performance on business performance through regression analysis. In order to develop the regression model between safety performance and business performance, the previous studies both for environmental management and for quality management had been reviewed. We obtained the result that the number of the injured persons in occupational accident and the number of lost work day because of the accident which are selected as measurement for safety performance had an effect on business performance through empirical analysis both for large 43 enterprises and for small and medium 30 enterprises. Also we had found that the control variables selectively 3had an effect on business performance. Finally, we concluded that the safety performance had an effect on business performance both for large enterprise and for small and medium enterprise.
