The purpose of this study is to prove the work efficiency of PDS by measuring the work time on the process of pattern making of woman's tailored jacket. Also compared to the manual work time, PDS work efficiency is estimated according to experience difference. The YUKA CAD system was used. Through analysis of PDS Process, work time was measured by stop watch. Also the appearance of the 2 jackets was evaluated by a pool of evaluators consisted of graduate students and experienced professional modelist. The results were as follows: The work efficiency of PDS is higher than the work efficiency of manual work. There were significant differences of work time between work types in the expert and inexpert group. A study compared the work efficiency by PDS work type with those by manual work type according to experience difference and found that the work efficiency by PDS in the expert group was 25.3%, in the inexpert group was 35%. There were significant differences of work time between experience groups in PDS work, the work efficiency of expert group to inexpert group in the total pattern making time by PDS was 36.7%. There were no significant differences of appearance of tailored jacket between work types.

본 연구의 목적은 국가핵심기술을 보유하고 있는 기업들의 물리보안수준이 보안성과와 업무효율성에 미치는 영향을 분석하는데 있다. 이를 위해 보안요원 200여명을 대상으로 한 달 동안 설문조사를 실행하였다. 설문조사에서 독립변수는 물리보안수준, 매개변수는 보안성과, 종속변수는 업무효율성으로 선정하였다. 신뢰도 분석과 타당성분석, 판별타당성분석 등을 SPSS를 통해 인과관계를 분석한 결과 "물리보안수준 ⇒ 보안성과, 보안성과 ⇒ 업무효율성"는 채택되었으나 "물리보안수준 ⇒ 업무효율성"은 기각되었다. 따라서 물리보안수준이 매개변수인 보안성과를 거쳐 업무효율성에 영향을 주는 것으로 조사되었으나 물리보안수준이 직접 업무효율성에 영향을 미치지 않는 것으로 나타났다. 향후 업무효율성을 향상시키기 위해서는 보안성과를 높이는 것이 우선되어야 할 것이다.

The purpose of this study is to develop the web-based system for work performance analysis(WPAS). The need of work performance analysis system has already been suggested in many previous researches on the computerization of the performance measurement in the construction site by using the indicators such as time, cost and quality. However, they had focused on measuring or analyzing the result when the project would be over. The WPAS suggests three indicators - work reliability, work effectiveness and work efficiency - to manage the performance of the construction site. It can help the manager more easily recognize the status of on-going work in the construction site by measuring and analyzing the work reliability rate, the work effectiveness and work efficiency every day. This research includes the procedures for WPAS measurement process, database structure of WPAS which was analyzed by the IDEF0 and the data flow diagram. Finally, this research introduces the result of WAPS's case studies and validation in the Korean construction site.

The objective of this research is to select the most effective technique among task related techniques(motion & time study, job redesign, physical environment improvement) for improving work efficiency in shipbuilding enterprise. This study consists of several principal steps. The first step is to design critical criteria in evaluating work efficiency in ship-building enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP(Analytic Hierarchy Process) structure using the critical criteria, sub-criteria and techniques among task related techniques. The fourth step is to develop the pairwise comparison matrix at each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique among task related techniques using AHP analysis. The result of AHP analysis has shown clear difference in priority among task related techniques in terms of work efficiency of the shipbuilding enterprise: The reduction of normal time is more important than the reduction of allowance time in improving of the work efficiency. Motion & time study is the most important technique for the reduction of normal time, and physical environment improvement is the most important technique for the reduction of allowance time as well.

This study has collected 322 clinical dental hygienists working in Daegu and around Daegu, in order to investigate perceived value of work among dental hygienists and extent of organizational attitude and find relationship between these, and we can finds these conclusions as follows; 1. The total average point of perceived value of work is 3.36(5 is a full mark), and we could gain each points as follows; vision realizability 3.53, process efficiency 3.42, product usefulness 3.32, job significance 3.31, social recognition 3.23. 2. The total average point of organizational attitude is 3.13, and job satisfaction, organizational commitment are 3.14, 3.12 respectively. 3. Variables of perceived value of work related job satisfaction are social recognition, vision realizability, process efficiency,(Social recognition is the most effective variable, and next vision realizability, process efficiency are effective in the order named.)($R^2$=.24) and we could find that job satisfaction is proportion to perceived value of work, according to relationship of these variables. Variables of perceived value of work related to organizational commitment are also vision realizability, social recognition, process efficiency,(Vision realizability is the most effective variable, and next social recognition, process efficiency are effective in the order named.)($R^2$=.32) and we could find that organizational commitment is proportion to perceived value of work, according to relationship of these variables. According to these result, perceived value of work and organization attitude(job satisfaction, organizational commitment) of dental hygienists are affirmative. but to make their attitudes be more affirmative, the research about improving perceived value of work is needed. Especially, vision realizability and social satisfaction are very important variables at perceived value of work of dental hygienists.

Over the past 30 years, the business effects of the improvement project at black spot have been decreasing since 2010, with a reduction in the amount of government spending, coupled with proposing a uniform improvement plan. In order to promote more efficient improvement projects, it is necessary to evaluate the efficiency of local governments and improve the business methods of local governments with low efficiency. However, more sophisticated efficiency analysis methods are needed. Because in previous studies have been limited to the analysis of effects before and after the project through the simple before-after analysis. For this purpose, this study analyzed the efficiency of improvement project at black spot by local governments in Gyeonggi-do using DEA to compare and analyze efficiency in various fields. As a result, Goyang, Seongnam, Paju, Hanam and Yangju showed high efficiency local governments. For local governmetns with low efficiency, the improvement projets to improve efficiency were divided into civil engineering work, structure work, pavement work, additional work and transportation work, and the appropriate construction ratios of each local government were analyzed and presented.

Background: This cross-sectional study assessed the sleep quality using the ActiGraph and investigated the relationship between the parameters of sleep assessment and the type of shift work in Korean firefighters. Methods: The participants were 359 firefighters: 65 day workers (control group) and 294 shift workers (shift work group: 77 firefighters with 3-day shift, 72 firefighters with 6-day shift, 65 firefighters with 9-day shift, and 80 firefighters with 21-day shift). Sleep assessments were performed using the ActiGraph (wGT3X-BT) for 24 hours during day shift (control and shift work group) and night shift and rest day (shift work group). The participants recorded bed time and sleep hours during the measurement period. Results: Sleep efficiency, total sleep time, and percentage of wake after sleep onset during night work were lower in the shift work group than control group (p < 0.05). Sleep efficiency decreased in night shift and increased in rest day, whereas wake after sleep onset increased in night shift and decreased in rest day (p < 0.05). Among shift work groups, sleep efficiency of 6-day shift was higher in day shift, and sleep efficiency of 21-day shift was lower in night shift than other shift groups (p < 0.05). Conclusion: We found that the sleep quality in night shift of the shift work group was poorer than the control group. As to the type of shift work, sleep quality was good in 6-day shift and poor in 21-day shift. Thus, fast rotating shift such as 6-day shift may be recommended to improve the sleep quality of the firefighters.
