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.

A comparative molecular field analysis (CoMFA) on the substituent effect of the palladium(Ⅱ) catalyzed [3,3]-sigmatropic rearrangement of allylic esters was studied to show a good correlation between the electrostatic property of substituents and the reaction rate. The CoMFA result suggests that the reaction rate will increase as the electron-donating ability of substituents increases.

The comparative molecular field analysis (CoMFA) method has been employed to correlate the apparent lipophilicity (logkw) and global lipophilicity (logP) for orthopramide derivatives. This study demonstrated that CoMFA is an excellent method in predicting the complex properties of molecules such as apparent lipophilicity (logkw) or lipophilicity (logP). The better predictability of lipophilicity by introducing logkw as an independent descriptor suggests that the HPLC capacity factor measured in a buffer of pH 7.5 (logkw) can be effectively utilized in the prediction of global lipophilicity.

A Gram-positive bacterium was isolated from the saline soils of Jangpura (U.P.), India, and showed high-level of radiation-resistant property and survived upto 12.5 kGy dose of gamma radiation. The 16S rDNA sequence of this strain was examined, identified as Bacillus sp. strain HKG 112, and was submitted to the NCBI GenBank (Accession No. GQ925432). The mechanism of radiation resistance and gene level expression were examined by proteomic analysis of whole-cell extract. Two proteins, 38 kDa and 86.5 kDa excised from SDS-PAGE, which showed more significant changes after radiation exposure, were identified by MALDI-TOF as being flagellin and S-layer protein, respectively. Twenty selected 2-DE protein spots from the crude extracts of Bacillus sp. HKG 112, excised from 2- DE, were identified by liquid chromatography mass spectrometry (LC-MS) out of which 16 spots showed significant changes after radiation exposure and might be responsible for the radiation resistance property. Our results suggest that the different responses of some genes under radiation for the expression of radiation-dependent proteins could contribute to a physiological advantage and would be a significant initial step towards a fullsystem understanding of the radiation stress protection mechanisms of bacteria in different environments.

Current percentage differential relaying has been recognized as the principal basis of main protection for stator windings of AC generator. The DWT has merit of obtaining frequency characteristics in time domain. In order to compensate for DFT's defects, we proposed fault detection algorithm using DWT. This paper describes a comparative analysis about conventional DFT-based DFR and advanced DWT-based relaying.

한국과 중국 모두 세계시장에서 재화무역에서는 수출경쟁력이 있고 서비스무역에서는 경쟁력이 없으나 양국은 서비스무역 비중이 확대되고 있고 FTA논의를 통해 양국간 서비스무역은 더욱더 확대될 전망이다. 이런 배경 하에서 본 논문은 한 중간 서비스산업의 부문별 수출경쟁력을 측정하는데 그 목적이 있다. IMF의 BOP 통계수치를 이용하여 한 중 양국의 서비스 무역에 대한 수출경쟁력을 측정하기 위해 무역특화지수(TSI), 수정현시비교우위(RSCA)지수와 국제시장점유율(IMS) 및 수출증가율을 사용해서 서비스무역의 국제경쟁력을 부문별로 비교분석하였다. 그 결과 한국은 운송서비스, 금융서비스, 특허권 등 사용료, 개인 문화 오락 부문 등 4개 부문에서, 중국은 여행서비스, 통신서비스, 보험, 컴퓨터 및 정보, 기타 사업서비스 부문 등 5개 부문에서 국제경쟁력을 가지는 것으로 평가되었다. 건설부문은 비교우위를 판정할 수 없었다. 그러나 중국이 비교우위를 가지고 있는 통신서비스와 컴퓨터 및 정보서비스부문은 비교우위격차가 축소되어 서비스무역의 국제경쟁력 강화노력이 이루어지면 중국보다 경쟁력에서 우위에 설 수 있다.

This purposes of this study is to develope policies on the facilities for the elderly care in Korea. Methodology of this study adopts comparative analysis on the facilities for the elderly care in 6 countries which have experienced various problems on the elderly. These 6 countries are Japan, Sweden, America, Australian, England and Germany. Major issues for comparative analysis are the standard of care facilities, residence condition, finance of facilities establishment and expense, operating system, management, and the law and administrative structure about the facilities for the elderly care. The elderly people need various kinds of welfare services such as medical care facilities, nursing home facilities, home care facilities etc.. Thus the public policies for the aging population nations are compose of income maintenance program, health and medical care services and social welfare services. The policies of facilities for elderly care are very important since these policies include the characteristics of income maintenance, me\ulcorner미 care program and welfare program. This study willsupply basic data for the development of facilities for the elderly care in Korea, especially conceming the system and institutional device of the facilities.
