In this study, when we make a diagnosis of constitution using QSCC Ⅱ(Questionnaire of Sasang Constitution Classification). data mining techniques are applied to seek the classification function for improving the accuracy. Data used in the analysis are the questionnaires of 1051 patients who had been treated in Dong Eui Oriental Medical Hospital and Kyung Hee Oriental Medical Hospital. The criteria for data cleansing are the response pattern in the opposite questionnaires and the positive proportion of specific questionnaires in each constitution. And the criteria for variable selection are the test of homogeneity in frequency analysis and the coefficients in the linear discriminant function. Discriminant analysis model and decision tree model are applied to seek the classification function into Sasang constitution. The accuracy in learning sample is similar in two models, the higher accuracy in test sample is obtained in discriminant analysis model.

A safe grounding design is used for providing means to carry electric currents into the earth under fault conditions without exceeding any operating limits and for assuring that a person in the vicinity of grounded facilities is not exposed to danger of critical electrical shock. Transformer neutral point grounding is for the purpose of controlling the voltage to earth within tolerable limits under a line-to-ground fault. Transformer frame grounding is for the purpose of minimizing the hazardous potential within safety criteria appearing at the faulted equipment. ills paper deeply investigates the grounding resistance effects of distribution power transformers by analysing the neutral to eatth voltages and touch voltages when the fault occurs.

Domestic LCD TV market is composed of two groups of products produced by major firms and small and medium enterprises. The major companies make the price relatively high, but the other makes lower in the same sizes. The model of the low price products does not make consumers choice when they choose LCD TV. This makes the questions of capability between difference price products. The reason above mentioned, the firms that include group of comparatively lower price, are worried about not increasing sale because of prejudice. This study is to find any interrelationship and evaluate the efficiency between the products using performance, exterior and brand power of product. In order to do this, a hybrid AHP/DEA evaluation model for comparison/valuation of LCD TV products is developed. The proposed process is; first, to derive hierarchy structure of LCD TV evaluation criteria using axiomatic design, second, to calculate the score of each LCD TV product through AHP analysis including weight calculation of evaluation criteria, and last, to evaluate the efficiency of LCD TV product by applying DEA by defining product scores as output and prices as input. It concludes that the high price products shows good efficiency, but there are some products with good exterior and brand power, not performance, also presenting good efficiency.

The advancement of information and communication technology has caused a few dysfunction such as hacking. To keep an organization from a harmful hacking, demands for cryptographic modules have been increased. However, the evaluation criteria of cryptographic modules in Korea have been less firmly established. It is difficult for the consumers of cryptographic module to choose an appropriate cryptographic module, and to establish interoperability between applications and cryptographic modules. This study analyzes evaluation criteria, evaluation processes and evaluation policy of CMVP(Cryptographic Module Verification Program) in the advanced countries. The paper suggests a policy for Korea CMVP, in resulting a provision of foundations for international standard and cooperations for international cryptographic policies and systems.

Under the present occupational therapy 6 items of overall coverage objects of health insurance are being applied and among them, only 3 items including the simple therapy, complex therapy, and special therapy can be demanded in the hospital. The treatment for Activities of Daily Living(ADL), Oral Motor Exercise and Functional Electrical Stimulation(FES) is exempted from an issue of reduction object, because it was covered 100% by the person himself. The reason why there are a lot of reduction factors is attributed mainly to vagueness of criteria and lack of exact understanding between therapists of insurance-applied hospitals. The reduction factors are characterized to confine them to only special treatment which demands the highest insurance cost claimed and to be applied without consideration of treatment times or days of hospital treatment. Moreover, the 56.38%, rate of reduction results from its uniform application based on willful convenience of health insurance not on embodiment of criteria or characteristics of various type of patients.

Development of a barrier system for floating debris at river is introduced. The system is to prevent pollution of coastal water caused by marine debris which originates from land. The system consists of harrier boom, mooring system and boom winder. The harrier boom, which is self-inflatable with circular band spring, guides floating debris to a collecting conveyer system. Design parameters of the harrier system were reviewed and its design criteria were established. Based on the established design criteria, a pilot harrier system was built and tested at Tanchon branch of the Han river. It is proved that the suggested system is very efficient to collect floating debris at river.

This study proposes an integrated technique of Genetic Algorishim (GA) and Geographic Information System (GIS) for designing the water quality monitoring networks. To develop solution scheme of the integrated system, fitness functions are defined by the linear combination of five criteria which stand for the operation objectives of water quality monitoring stations. The criteria include representativeness of a river system, compliance with water quality standards, supervision of water use, surveillance of pollution sources and examination of water quality changes. The fitness level is obtained through calculations of the fitness functions and input data from GIS. To find the most appropriate parameters for the problems, the sensitivity analysis is performed for four parameters such as number of generations, population sizes, probability of crossover, and probability of mutation. Using the parameters resulted from the sensitivity analysis, the developed system proposed 110 water quality monitoring stations in the Nakdong River. This study demonstrates that the integrated technique of GA and GIS can be utilized as a decision supporting tool in optimized design for a water quality monitoring network.
