Ergonomic intervention techniques were adopted to assess and control potential risk factors of work-related musculoskeletal disorders(WMSDs) in the automated light assembly manufacturing system. Ten different kinds of assembly workstations implemented with a conveyor system and twelve female workers were observed and evaluated with careful video film analysis. Several close examinations using sets of checklists established by qualified safety and health organizations, such as NIOSH, OSHA, and ANSI, were conducted and every workers and staffs in the site participated in the self-report questionnaires and off-line interviews. Typical risk factors and symptoms of the upper extremity musculoskeletal disorders were found and categorized into specific parts of body. To reduce risk factors of WMSDs and improve system productivity new revised workstation standards, physical dimensions, were suggested accordant with anthropometric characteristics of workers and a heuristic decision strategy of rotating shift work schedules according to work contents has proposed to mitigate cumulative physical stress. Finally, ergonomic programs of entire company to prevent WMSDs were structured.

Purpose: The purpose of this study was to test the validity of a modified clinical performance examination (CPX) for preclinical students in nursing. Method: 70 nursing students in their second semester of the junior year at C University participated in CPX. Scenarios and checklists were developed by our research team from September to October 2005. Six stations were organized. Evaluation included physical examination of a patient with lung cancer, education on usage of a metered dosage inhaler, and lobectomy postoperative care. Students were randomly assigned to a station. Result: There was a difference in the CPX scores according to stations. The agreement of scoring between trained faculty members and SPs was more than moderate (r=.647). The correlation between the CPX score and the average grade in the previous semester and between the CPX score and the average grade of a paper and pen test of the pulmonary system of adults was low (r=.276; r=.048). Conclusion: Traditional CPX is generally recommended, however, modified CPX is appropriate for preclinical students in the current Korean Nursing school setting if there are additional scoring systems to balance the testing level at each station.

Background: Tasks involved in traditional charcoal production expose workers to various levels of charcoal dust and wood smoke. This study aimed to identify specific tasks influencing lung function and respiratory symptoms. Methods: Interviews, direct observation, and task/symptom checklists were used to collect data from 50 charcoal-production workers on 3 nonwork days followed by 11 workdays. The peak expiratory flow rate (PEFR) was measured four times per day. Results: The PEFR was reduced and the prevalence of respiratory symptoms increased over the first 6-7 workdays. The PEFR increased until evening on nonwork days but not on workdays. Loading the kiln and collecting charcoal from within the kiln markedly reduced the PEFR and increased the odds of respiratory symptoms. Conclusion: Tasks involving entry into the kiln were strongly associated with a short-term drop in the PEFR and the occurrence of respiratory symptoms, suggesting a need for the use of protective equipment and/or the operation of an effective kiln ventilation system.

Mothers of 58 20-month-olds in Seoul, the Republic of Korea, completed vocabulary checklists for their children. When vocabulary level was taken into account, children's vocabularies contained relatively greater proportions of nouns than other word classes, and more verbs than adjectives or closed-class words. Correlations among word classes showed that each word class was consistently positively correlated with every other class. Girls' vocabularies showed evidence of being larger than boys. Large individual differences in the sizes of children's vocabularies were found. Factors that influence vocabulary size and can account for gender and individual differences are discussed. Noun prevalence in the vocabularies of children learning to speak Korean, and the merits of several theories that may account for this word-class prevalence pattern, are evaluated.

Purpose: This study was done in order to identify the effectiveness of open laboratory self-directed practice on knowledge, self-confidence, skill competency, and satisfaction of intravenous infusion in nursing students. Methods: This is a quasi-experimental study using a non-equivalent control pre-posttest design. The participants were 32 students comprising an experimental group and 30 students comprising a control group. The experimental group was allowed to perform open laboratory self-directed practice only. Pretest and posttest was performed through questionnaires of knowledge and self-confidence, and competence and satisfaction were assessed using checklists at posttest. Results: The score of Knowledge in the posttest showed no significant difference between both groups (F=1.28, p=.290), and those of self-confidence (F=3.87, p=.014) and competency (F=9.55, p<.001) of the experimental group were significantly higher than those of the control group. Conclusion: Open laboratory self-directed practice was effective in improving nursing students' self-confidence and competency of intravenous infusion. Therefore, students should be encouraged to actively participate in open laboratory self-directed practice and the effective strategies should be developed.

건설사업은 그 규모와 복잡성으로 인하여 다른 산업에 비해 위험에 대한 노출수위가 크고, 그 형태도 다양하다. 따라서, 건설사업에서 위험을 인지하고 대응하는 일련의 위험관리 과정은 정확하고 체계적으로 수행되어야 한다. 위험관리 과정에서 위험인지 단계는 다양한 위험요인의 인지와 그 위험의 성격을 규정하는 단계이고. 이러한 위험인지 단계에서 위험분류체계는 사업에 내재된 다양한 위험을 인지하게 해주는 유용한 도구이다. 본 연구에서는 기존 위험분류체계의 문제점을 개선하고 재정립함으로서, 실질적인 건설사업에서 위험인지 도구로서 활용될 수 있는 사업단계별, 계약주체별 체크리스트를 제안하였다.

As the importance of electronic commerce(EC) increases, some people argue that traditional commerce(TC) will ultimately give way to EC in the near future. Regardless of the type of commerce, however, it is the value factors of the customer that would formulate the direction of change in the market. This study investigates the influence of those value factors upon the attitude towards the type commerce and the repurchase intention of products and service. It also addresses the impact of the customer's risk disposition and level of confidence. A number of customer's value factors are hypothesized to affect the attitude, and the attitude in turn is expected to be related to the repurchase intention. Based on two hundred and ninety responses from the computer survey, the hypotheses are tested. The convenience, cost reduction, and information satisfaction factors affect EC attitude and repurchase intention. Similarly, the reliability, personal interaction, and shopping enjoyment factors affect TC attitude and repurchase intention. The comparison between EC and TC factors indicates the significant difference in the time saving factor in favor of EC. The personal characteristics such as risk disposition and level of confidence also influence the attitude and repurchase intention. The implications and limitations of this study are discussed. The value factors identified in this study may serve as important checklists for those firms already in EC and those intending to enter the market.

Characteristics of Superior Children as a Screening Test of Gifted students The purpose of this study was to investigate the usefulness of Korean version of checklist for behavioral characteristics of superior children as a screening test for gifted students. Total 397 children were tested KEDI-WISC (Korean version of Wechsler Intelligence Scale for Children), and their parents or primary caretakers took the checklists for behavioral characteristics of superior children individually. Total subjects were divided into 3 groups based on their Full IQ score of KEDI-WICS. The children of IQ 130 and over was gifted group, and those of IQ 115-130 was superior group, and those of below IQ 115 was average group. The analyses of behavioral checklist scores among the groups, gender, grades differences and item analysis of behavioral checklist were done for the purpose of discrimination among 3 groups. As a result, it was found that the Korean version of checklist for behavioral characteristics of superior children was very useful as a screening test for gifted correlations between checklist scores and verbal, performance and full IQ scores were significantly high, which means that IQ and checklist scores were very related. Twenty out of 50 items were found to be discrimination items between gifted and superior group. However, there was no significant difference between grades and gender on the checklist score.
