This paper illustrates the application of Fuzzy Theory and Analytic Hierarchy Process(AHP) for developing Occupational Stress Index(OSI). The purpose of the OSI development is for future prediction and problem solving of prevailing occupational stress. In developing OSI, the concept of fuzzy set theory was introduced to determine the existence and level of perceived occupational stress instead of actually measuring the strain parameters. The AHP is adopted to collect different weighting factors, since there exist various perceptions and responses to the occupational stress by different individuals. The validation study revealed that the OSI is a reliable predictor of work-related accident and illness and the physiological health of employees. Creating preventive measures, such as early detection of stress, proper placement and promotion of employees, and job enlargement will be possible by using this OSI effectively.

The purpose of this paper is to propose alternatives to help for the aged to implement start business as a method to recreate the aged population for their second life. There are three considerations that supports start business for the elderly. The first is to reinforce educational support system for the aged. Through the lifelong education, the aged require easy start business' information. This is not only goverment's job, a local autonomous entity is to support in the form of organic organization. The second is the maintenance of financial support system. Besides start business education, various financial support system must serve for the aged to challenge their start business enthusiastically. The last consideration is formation of start business network that joins the aged efficiently. Based on these aspects, the application for increasing elderly human resource is to consider both employment program of the aged and also start business program for them.

This paper presents the development of event-driven system level simulation tool SMPLE(Smpl Extende, an extention fo smpl) and its application to the performance analysis of multiprocessor computer systems. Because of its data structure, it is very difficult to change, expand or add new functions to simulation language smpl implemented by MacDougall. In SMPLE, we change data structure with structure and pointer, add new functions, and enable dynamic memory management. Using new data structure, facilities, and functions added in SMPLE, we simulate job processing of a shared bus multiprocessor system with autonomous hierarchical I/O subsystem. We set system performance contribution of subsystems and units. The impact of disk I/O on system performance is evaluated under vairous conditions of number of processors, processing power, memory access time and disk seek time.

Along with the increase of the quantity of data in various industries, the construction industry has also developed various systems focusing on collecting data related to the construction performance such as productivity and costs achieved in construction job sites. Numerous researchers worldwide have been focusing on developing efficient methodologies to analyze such data. However, applications of such methodologies have shown serious limitations on practical applications due to lack of data and difficulty in finding appropriate analytic methodologies which were capable of implementing significant insights. With development of information technology, the new trend in analytic methodologies has been introduced and steeply developed with the new name of "big data analysis" in various fields in academia and industry. The new concept of big data can be applied for significant analysis on various formats of construction data such as structured, semi-structured, or non-structured formats. This study investigates preliminary application methods based on data collected from actual construction site. This preliminary investigation in this study expects to assess fundamental feasibility of big data analytic applications in construction.

Cumulative trauma disorders(CTDs) have been a growing problems for US and European industries with higher incidence rate every year. The increase and their associated costs has led companies to form committes and implement programs to address this problem. In our country, we have just started to recognize and to work on the problems in industry. This study conducted an ergonomic analysis for typical jobs of ship building industry which was not usually surveyed for CTD problem. A baseline CTD checklist which was supposed to do a risk assessment was developed and applied in this study. Initially, we considered five major parts in the checklist which consisted of personal, frequency, posture, force, and miscellaneous information. Most jobs in ship building industry were much different from typical assembly work and VDT work that have been major part of the previous CTD studies. Specifically, job characteristics in terms of frequency and posture were quite different. There were relatively long cycle time, awkward postures for whole body (not just for upper extremities). Also, CTD risk scores based on checklist were a lot higher than the scores for VDT jobs which was a case of preceding application of the checklist. Specifically, grinding jobs turned out to be the most risky one in terms of CTDs. In conclusion, usual CTD prevention guidelines are not likely to he effective in this type of industry. An individual job based interventions are strongly suggested to have a good control of CTD problems in ship building industry.

고속의 컴퓨터, 대용량 저장장치, 초고속 네트워크는 현재 우리가 쉽게 접근할 수 있는 컴퓨팅 인프라이다. 하지만 분자 시뮬레이션과 같은 자연과학 및 응용과학 분야에의 시뮬레이션에서는 여전히 더 많은 컴퓨팅 파워, 더 커다란 저장장치를 필요로 한다. 이러한 요구는 그리드 컴퓨팅(1)이라는 차세대 분산 컴퓨팅 환경을 우리에게 제시하였다. 하지만 현재까지 제안된 그리드 컴퓨팅 기술은 통신 인터페이스와 프로토콜 등의 글로버스 툴킷(2, 3)과 같은 미들웨어 수준에 대한 연구만이 중심이 되고 있다. 이러한 환경은 응용 플랫폼에 대한 연구의 부족과 어플리케이션의 부족을 가져왔으며, 그 결과 사용자는 그리드 컴퓨팅 기술에 대한 이용을 미비하게 만들었다. 따라서 본 연구에서는 분자 시뮬레이션 그리드 (MGrid: Molecular Simulation Grid System) 에서 적용을 목적으로 고효율(High Throughput)의 시뮬레이션 실험을 위한 사용자 환경(User Environment)을 정의하고, 사용자에게 친근한 추상화된 작업 모델을 제안함으로써 보다 효율적이고 안정적인 그리드 자원 이용을 가능하게 한다.(4, 5)

Purpose: This study was conducted to evaluate the performance following the application of the pilot program for the education nurse system of the Ministry of Health and Welfare in a medical institution. Methods: This study was employed a non-homogeneous comparative group design by comparing new nurses who entered the medical institution after the pilot project from December 2019 to April 2020 with new nurses who entered before the pilot project during the same period. Satisfaction, academic achievement, job adaptation, personal turnover within one year, and patient safety incident rate were investigated as performance indicators. Results: After the pilot project, the overall satisfaction among new nurses, preceptors, and fellow nurses increased, but there were no significant changes in academic achievement and job adaptation in new nurses. The personal turnover rate decreased from 15.6% to 9.1%, and the patient safety incident rate also decreased from 26.3% to 15.7%. Also, the preceptor overtime also decreased from 3.67 to 0.66 hours. Conclusion: The performance of the pilot project for the education nurse system was related to improvements in satisfaction, turnover rate of new nurses, patient safety incident rate, and preceptor overtime. Above all long-term monitoring of each performance indicator is necessary through the continuation of the education nurse system of the Ministry of Health and Welfare.
