Techniques related to railroad industry have progressed rapidly and the automation of work is prevailing. Since the railroad accidents due to the human error occupy considerable proportion among the railroad accidents, it is necessary to study the propriety of the physical examination system for the railroad workers. In this paper, we perform a comparative analysis of domestic and foreign physical examination systems for railroad workers. Through the comparative analysis, we suggest that test of the sleep-disorder be included in the physical examination.

Comparative study was conducted on the Human Resouces Management Practices between U.S.A. and Japan with reference to their socio-cultural tradition and environments. Special attention were given to those topics as prevailing value system in both country underlying human and organizational behavior, authority and responsiblility taking manner, inter-personal and social relations within conporate entity and society at large, and finally the pattern of individual involvement to the organization. The results clearly revealed that the sovio-cultural enviornmentsin respective country functions as the major influencing attributes in the formulation of current management practices.

This paper reports a comparative study for performance evaluation guidelines for bridge bearings. Guidelines for bridge bearings such as KS, EN1337, AASHTO LRFD, and Japanese code were analyzed. In addition, fatigue tests of elastomeric bearing are being conducted for allowable shear deformation and compressive stress. Based on literature survey and tests, the innovative concept of performance evaluation guidelines for bridge bearings is suggested.

The predictive results between a dynamic food-chain model (DYNACON) and an equilibrium model (NRC model) were compared to show the physical validity of DYNACON. Although the mathematical formulations and transport processes of radionuclides in the environment are different between two models, the comparative study shows good agreement for deposition events that occur during the growing season of plants.

본 연구는 1991-2012년간 동아시아 국가 간 산업별 부품무역의 비교우위를 분석하여, 동아시아 FTA 체결 시 예상되는 무역과 생산분할 구조를 분석한다. 분석기간 중 동아시아 내 부품무역의 상호의존도는 지속적으로 증가하여 왔으며, 동아시아 FAT 체결 시 구조적 변화가 없다면 한국과 일본이 동아시아 내 전기 및 전자기기, 수송기기 부품수출을 더 강화하고, 중국과 ASEAN이 최종재를 수출하는 구조는 유지될 것으로 예상된다.

In the literature study by the comparative method was carried out on the book of an Introduction to oriental medicine, which was published in China, recently. The results were as follows: The contents of the book was divided by Introduction, Um-Yang-O-Hang(陰陽五行), Qi-Hyul-Chinec(氣血津液), Jang-Bu(臟腑學說), Meridian(經絡), Etiology, Diagnosis, and treatment. This study did not treat the Ancient Chineses character hard to understnad, methodlolgy of traditional literature, and comparison to the western medicine.

Since the 90's, the world's aerospace industry have been experienced the era of radical changes. We make a comparative study about the 10 countries government policies and corporate strategies changes in this era. In this study, we figure out aerospace industry's evolutional patterns and factors through evolutionary perspective, and then, proposed development strategies and implications for Korea's aerospace industry.

As remote sensing is weighty in GIS updating, it is indispensable to get spatial information quickly and exactly. In this study, we have designed and implemented the program by two algorithms of GDPA (Gradient Direction Profile Analysis) and Hough transformation to extract linear features automatically from high-resolution imagery. We applied the software to embody both algorithms to KOMPSAT-EOC, IKONOS, and Landsat-ETM and made a comparative study of results.

Objectives : Since The Journal of Korean Acupuncture and Moxibustion Society(JKAMS) started publishing in 1984, randomised controlled trials(RCTs) and non-randomised clinical studies(NRSs) consistently have increased in quality and quantity. There has been no study on quality assessment of NRSs. Thus, this study evaluted non-randomised comparative clinical trials in the JKAMS to assess the quantity and quality. Methods : Upon extracting NRSs for assessing the intervention effects from all the articles published in the JKAMS from 1984 to 2009, assessments were made on methodological index for non-randomised studies(MINORS). Also, the analysis were made upon the proportion of non-randomised comparative clinical trials within original articles. The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed. Results : A total of 44 trials on non-randomised comparative clinical trials were selected. In 1980s, 4.3% of the total selected original articles, in 1990s, 4.1%, and in 2000s 14.2% were NRSs. According to the research designs, the mean scores of MINORS were Case-control study 18.3, Controlled before and after 18.5, Quasi randomised trial 18.5, and non randomised trial 17.9(out of 24), respectively. Cross-sectional study was the most frequently used(41.9%). Conclusion : Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used Cross-sectional study. Thus, there should be studied using appropriate research methods in the future.

Since the railroad accidents due to the human error occupy considerable proportion among the railroad accidents, it is necessary to study the propriety of the physical examination system for the railroad workers. Our government is promoting some systematic supplementation for railroad safety on the basis of the Railroad Safety Act. In this paper, we perform a comparative analysis of domestic and foreign physical examination systems for railroad workers. We also compare the physical examination system for public officials with that for railroad workers. Then we consult expert opinions of the Korean Society of Occupational and Environmental Medicine. Through the comparative analysis, we provide useful information that is needed to amend the physical examination system.
