The purpose of those study is to estimate grip and hand activity of RA patients and find that the evaluation is very a valuable to the RA patients. The term of the evaluation was from June 25. 1998.. to July 30. 1998 and researched at Hanyang university Rheumatic Hospital. This study researched 100 normal people and 85 RA patients and analyzed the results and averaged those with t-test by Excel data. The results of those study are as follows. 1. The highest percent of those results of the dynamometer, pinch research was the people who are on 40s. 2. The results of all RA patients marked lower than those of normal people. 3. It's difficult to do hard work such as washing, opening can, transferring boxes to the patients. 4. The above research is effective to RA patients.

Reasonable disaster prevention signs play an important role in guiding evacuation. Through the field investigation on disaster prevention signs in shelters and surrounding areas in Beijing, some problems were found in the using of sign system. Based on the principle of integrated design, evacuation and rescue requirements, it is necesssary to make further study on aspects such as, design of function, systematic consideration, humanization design, as well as the internationalization using. This paper presents an evaluation index system for disaster prevention signs. Such a system is very important for strengthening the independent guiding function of sign systems and improving evacuation efficiency. An effective connection could be realized between the internal environment of buildings, evacuation routes, and emergencey shelters.

This paper illustrates a new method for reliability evaluation at load points in a composite power system. The algorithm includes uncertainties of generators and transmission lines as well as main transformers at substations. The CMELDC based on the new effective load model at HLII has been developed also. The CMELDC can be obtain from convolution integral processing of the outage capacity probabilistic distribution function of the fictitious generator and the original load duration curve given at the load point. The CMELDC based on the new model at HLII will extend the application areas of nodal probabilistic production cost simulation, outage cost assessment and reliability evaluation etc. at load points. The characteristics and effectiveness of this new model are illustrated by a case study of a small test system.

Port Authority in Korea does not have financial independence nor fair recruitment practices, thus the prospects of the establishment of the Port Authority is not adequate. Therefore independent and effective port administration cannot be achieved. To overcome this situation, this paper examines the port administration system in Korea and identifies its problems. This paper then provides an 'modeling of Analytical Hierarchy structure' for evaluation. An alternative solution is provided by carrying out a public survey, analysing the significance of the evaluation factor using the techniques of the Analytical Hierarchy Process. The significance of profitability was identified. The role of central government is significant when assessing the public service function of port administration; and the role of the private company is significant when assessing the independence. In addition, the private company is significant when assessing profitability. The private company is the alternative for port administration in Korea, based on the evaluation of various alternatives.

The purpose of this paper is to develope the evaluation technique to find proper elastic constants that characterize the material nonlinearity of structural membrane. The stress-strain curves of membrane material show strong nonlinearity. But generally the analysis is carried out under the assumption on material linear and geometrical nonlinear method. Because, it is very difficult to evaluate proper tangential stiffness. This paper use multi-step-linear approximation method taking the concept of effective stress for the evaluation of stiffness of membrane material, and then compare the results between linear and nonlinear analysis. Also. it shows better results than linear method

In recent years, domestic e-learning market has made rapid progress in its quality and quantity with the astonishing rate growth of internet. Although educational Websites are replacing the traditional second level education market, many of those Websites' contents have poor or unknown quality. To build an effective educational Website, it is essential to have clear evaluation criteria. Therefore, this study aims to examine what evaluation factors influence the satisfaction level of educational Websites for elementary school students. In conclusion, implications are discussed along with limitations and future research direction.

마취는 수술전 환자평가로부터 시작된다. 환자평가의 목적은 수술에 앞서 환자가 정신적으로나 신체적으로 최상의 상태에 있도록 하여 수술과정에 발생할 수 있는 이환율(morbidity)과 사망률(mortality)을 감소시키는데 있다. 환자의 정보를 수집하고 신체상태를 평가하여 마취계획을 세우기 위해서는 환자를 직접 만나야 한다. 수술전 환자방문은 안전과 효과적인면에 있어서 수술중 환자 관리만큼이나 중요하다.

The purpose of this study is to execute the investigation of injurious factors causing muscle-skeletal diseases at an automotive glass manufacturing company and, on the basis of the results, to enhance productivity by the improvement of working environment. By using an survey and an ergonomic evaluation method, symptoms of muscle-skeletal diseases of workers and working postures at each process were analyzed, and quantitative evaluation of muscle-skeletal disease risk against each process was performed. Based on the result of the evaluation, to enhance the working environment, improvement of worktable, working space, tools, and outfit was suggested, and induction of mechanical system was also suggested. Suggested improvement plan was applied to the workplace step by step and it is confirmed that improvement plan not only removes the injurious factors of muscle-skeletal diseases but also is effective to enhance productivity.

This paper was concerned with the risk evaluation of oxidizing substances by burning test method. The samples were prepared the heaped cone-shaped mixtures of solid oxidizing sub-stance with sawdust, and ignition of the sample was made on contact with heating wire inside the combution chamber that the temperature and humidity of atmosphere can be kept at $25^{\circ}C$ and 60% respectively. Accordingly, it were measured the combustivity effect of mixing ratio and amount of sample weight on the burning rate. As a result of burning test of these samples, it could be noticed that the case when the sawdust has so and 30 wt.% in the mixing ratio shows effective combustivity, and as the amount of sample weight was increasing, It showed more rapid burning time. So the average burning time could be obtained by considering the weighting factors to the parameters of the mixing ratio and the amount of sample weight. Finally, it was compared with the effects of cation and anion of oxidizing substances and also applied analytically to the classification and evaluation of oxidizing sub-stances as dangerous goods.

This paper deals with a performance evaluation model of transporters in refrigerate warehouse. This study focussed on determining refrigerate warehouse design to minimize the expected travel time to improve the transporter performance and to minimize the operating costs. This study proposes the important detail aspects of refrigerate warehouse design, operational parameters and congestions. For solving this problem, we have shown a mathematical model to compute the initial value of the system performance and also a simulation model using AutoMod. A systematic approach proposed in this study for an optimal planning of order-picking warehouse is known as an effective method for the planning of order-picking warehouse and a performance evaluation problem of refrigerate warehouse operation.
