The stream generator tubes represent an integral part of a major barrier against the fission product release to the environment. So, the rupture of these tubes could permit flow of reactor coolant into the secondary system and injure the safety of reactor coolant system. Therefore, if the crack was detected during In-Service Inspection of tubes the cracked tube should be evaluated by the pulgging criteria and plugged or not. In this study, the fracture mechanics evaluation is carried out on the thru-wall axial crack due to Primary Water Stress Corrosion Cracking in the roll transition aone of steam generator tube to help the assurence the integrity of tubes and estabilish the plugging criteria. Due to the Inconel which is used as tube material is more ductile than others, the plastic instability repture theory was used to calculate the critical and allowable crack length. Based on Leak Before Break concept the leak rate for the critical crack length and the allowable leak rate are compared and the safety of tubes was given.

In order to sustain competitive advantage through strategic product differentiation in global market, this research aims to establishment of strategic design conditions for domestic manufacturing firms through the means of product image alignment and positioning, using visual character of product as the foundation for establishing corporate image. Case studies on how globally successful multinational companies manage design strategy and corporate culture uniformly for coherent product image management are reviewed. To establish product image alignment methodology for manufacturing firms, the criteria for product image positioning and aligned product image development process are developed in three stages. First, in image positioning stage, it is important to set the direction for corporate image and design strategy by identifying consumer needs through market trends analysis and forecasting as well as comparative positioning of the analysis results of the firms's own corporate image and that of the competitor's. Second, in awareness building stage, before building the product image alignment, firm-wide shared awareness of differentiated corporate and product image, establishment of designer's role as the consolidated manager of product image, sharing form language, and building the infrastructure for defining form information should be preceded. Third, in managing the aligned product image stage, the condition for setting up image information management guideline, management of decision making process for arriving at logical decisions on product form, development of guideline for increasing efficiency and its evaluation system, and co-development of related design should be induced. Further research on the product image alignment with corporate image should be conducted through various empirical studies on image and form, building an information system of related design language, and continuous assessment and management of applied solutions.

The term rules of origin(RoO) actually speaks for itself, referring to the rules which determine the origin of goods in international trade. The importance of RoO has grown significantly as preferential agreements expand and countries have treated similar imported goods differently according to where the product was made. The purpose of this paper is to study the main case study and its implication of RoO in FTAs. According to survey, the degree of using FTAs in Korea export firms is sharply low. Major reasons are that rules of origin differ from country to country in the FTAs, and that Korean firms have yet to work out what the RoO are. Chapter II of this paper views criteria of the determination country of origin of goods. Chapter III introduces the main case study of FTA rules of origin. Chapter VI presents implication through the case studies and finally concluded this study. In conclusion, Korea needs to build up its own position for rules of origin and provides rules of origin experts into the market. In-depth study and evaluation about Korea's existing FTAs RoO should be carried out to prepare for future FTAs.

Biphenyl dimethyl dicarboxylate (DDB) has been used for the treatment of chronic viral hepatitis B and drug-induced hepatitis through the inhibition of lipid peroxidation and c ovalent binding of drug metabolites to lipids of microsomes. The bioequivalence of two DDB products was evaluated according to the guidelines of KFDA. The test product was Hepaphil soft capsule(R) made by KMS Pharm. Co. Containing 3 mg DDB and the reference product was Nissel tablet(R) made by Taerim Pharm. Co. Containing 25 mg DDB. Twenty healthy male subjects, 25.4(22~30) years old and 66.7(54~77)kg, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After two tablets or two capsules were orally administered, blood was taken at predetermined time intervals and the concentration of DDB in plasma was determined using a validated HPLC method with UV detector. Two pharmacokinetic parameters, $AUC_t$ and $C_{max}$, were calculated and analyzed statistically for the evaluation of bioequivalence of the two products. Analysis of variance was carried out using logarithmically transformed parameter values. The 90% confidence intervals of $AUC_t$ and $C_{max}$ were log 0.91~log1.00 and log 1.05~log 1.15, respectively. These values were within the acceptable bioequivalence intervals of log 0.8 to log 1.25. Thus, the criteria of the KFDA guidelines for the bioequivalence was satisfied, indicating that Hepaphil soft capsule is bioequivalent to Nissel tablet.

In order to discover novel potent antitumor agents, methanolic extracts of approximately 180 herbal medicines were prepared and primarily evaluated for cytotoxic activity in cultured human lung (A549) and colon (Col 2) cancer cells. As a result, 17 natural product extracts were found to be active in the criteria of $IC_{50}$<$20\;{\mu}g/ml$. Especially, the extracts of Aristolochia debilis, Cynanchum ascyrifolium, Cynanchum paniculatum, Daphne genkwa, Euphorbia lathyris, Ipomoea hederacea, Magnolia officinalis, Melia azedarach var. japonica, Solanum nigrum, Thuja orientalis, and Trichosanthes kirilowii showed a strong cytotoxic potential. The flower extract of Daphne genkwa was more selective cytotoxic activity against lung cancer cells $(IC_{50};\;0.2\;{\mu}g/ml)$ compared to colon cancer cells $(IC_{50}>20\;{\mu}g/ml)$. In addition, based on the cytotoxic potential of the root extract of Cynanchum paniculatum, the further fractionation of methylene chloride partition with silica gel column chromatography was performed. Several subfractions were considered to be active, and thus indicating that further studies for the identification of active principles from these fractions might be warranted.
