This paper deals with an approach to the reduction of potential rise according to the buried depth of structure. In order to analyze the surface potential rise of structure, an electrolytic tank which simulates the semi-infinite earth has been used. The potential rise has been measured and analyzed for types of structure using an electrolytic tank experimental apparatus in real time. The structure models were designed through reducing real buildings and fabricated with two types on a scale of one-one hundred sixty When a test current flowed through structure models, the potential rise of outline frame type(structure model A) was more high than that of electric cage type(structure model B). The distributions of surface potential rise are dependent on the buried depth of structure model.

The effect of additional amounts of subsidiary materials on texture of fish meat paste were examined using Instron Universal Testing Machine to obtain fundamental data for steamed Alaska pollack meat paste showing good quality. The hardness revealed the good correlation with jelly strength among the six kinds of parameters of Instron texturometer. Products with higher hardness showed a better quality, but those with hardness higher than 16kg showed decreasing quality with increasing hardness. Predicting the quality of steamed Alaska pollack meat paste with various additional amounts of subsidiary materials as a function of hardness, H, the equation could be deduced as follows: H=11.56+0.54Xcs, H=12.22-0.23Xsp and H=11.65-7.13Xpp. The reasonable equations for predicting the quality of steamed Alaska pollack meat paste with various additional amounts of mixed subsidiary materials could be summarized as follows: H=11.57+0.53Xcs+0.44Xsp, H=11.97-1.83Xpp-0.17Xcs, and H=11.58+0.08Xpp-0.23Xsp.

Design works consist of essential works and subsidiary works. Essential design works means designing creative ideas and productive ideas, while subsidiary design works means helping essential works those are making data tables and specification sheets, checking CAD data's integrity. Subsidiary design works forms the bulk of the whole design process and affects the time limit of delivery. Therefore we propose the automatic data matching system for CAD data's integrity. Proposed system is automatic system supporting subsidiary design works. The data matching system consists of three parts; 1) automatic generation of data tables 2) supporting module for checking CAD data's integrity between Drawings 3) automatic generation of spec. sheets. Developed system was tested in LCD equipment manufacture company and was found to be useful system.

Subsidiary welfare facilities in an apartment complex are one of the most important factors for consumers when they buy an apartment due to an increase of consumers' consciousness level, increase of leisure time, and increase of cultural life. This study aims to analyze layout types and characteristics of subsidiary welfare facilities at the apartment complexes in the second phase new towns, investigate the current situation and find out the improvement direction. For this purpose, this author investigated three "second phase new towns" which were designated as a new town at similar time, and selected a total of 15 apartment complexes by selecting 5 complexes in each of the three new towns. Literature survey, case visit, photo shoot, user observation survey were used as study methods. The results of the study are as follows. First, it was found that a mixed type was the most common type of plane layout types in the subsidiary welfare facilities. This type improves accessibility and equity of the residents as the facilities are appropriately placed based on the functions and the user characteristics. Second, it can be considered that a distributed type for senior citizen centers and daycare centers may give independence to specific users, but it may give a sense of alienation to the elderly. Moreover, it does not have enough community so that it is necessary to make proper supplementation. Third, there were two lay out types. The first one is that the subsidiary welfare facilities are placed with step difference and the second one is that they are placed in sunken places using the underground space. Fourth, all layout types of outdoor facilities are distributed types, and it is considered that measurements for a proper balance of accessibility and equity are required.

Recently, Korean customs authorities have attempted to impose customs duties on the warranty charges paid by Korean subsidiaries ("the taxpayers") of multinational corporations to their overseas headquarters, or their affiliates, as indirect payment of the price actually paid or payable for imported goods and services, and the taxpayers' complaints have been steadily increasing. The key issue of Korean Supreme Court decision, 2018Du56619, revolves around opposing interpretations of the Korea Customs Act and the WTO's Customs Valuation Agreement in determining who is responsible for paying duties levied on warranty charges. The Supreme Court's ruling was consistent with its previous interpretations of the WTO agreement on customs valuations. The Supreme Court ruled in favor of the plaintiff, a Korean subsidiary, stating that the overseas corporate headquarters' payments of warranty charges to Korean dealers are made on behalf of the Korean subsidiary, which is ultimately responsible for covering warranty charges. Thus, the Korean subsidiary's settlement of the warranty charges to their Korean dealers through the overseas headquarters is effectively the same as a direct payment to the dealers. Therefore, the Korean subsidiary performed warranty services on its liability and account. As such, the court ruled that warranty charges should not include tariffs on the indirect payment for warranty services in such cases. This paper presents the comparative legal implications for the warranty charge clauses in the WTO agreement and the Korean Customs Act and analyzes the Supreme Court's decisions.

Purpose - This study aims to identify the importance of subsidiary entrepreneurship as a key factor when MNE attempts to invest in challenging overseas markets. Through the simultaneous consideration of institutional theory and entrepreneurship theory, this study would like to examine how Korean subsidiaries in the Middle East improve their performance locally. Design/methodology - To reflect the characteristics of emerging markets, this study conducted a survey of Korean subsidiaries in the Middle East in cooperation with KOTRA and analyzed the hypotheses using a structural equation model based on 249 valid responses. Findings - The findings of this study are as follows. First, we found that institutional and business distance would positively affect subsidiaries' entrepreneurship. The result that subsidiaries' entrepreneurship is positively affected by institutional and business distance implies that attempts to close the difference between heterogeneous markets would increase subsidiaries' innovative proactiveness, such as R&D and creative marketing strategies. Second, we confirmed that the institutional and business distance positively mediate the subsidiaries' entrepreneurship growth, leading to high performance. Therefore, Korean subsidiaries are required and prepared to establish strategies to better understand institutional and business distances in advance and reduce the liability of foreignness by conducting customized research and training programs before sending Korean expatriates to local subsidiaries in the Middle East. Originality/value - This study contributed to institutional and entrepreneurship theory by proving the traditional relationship between institutional and business distance to subsidiaries' performance and the mediation of subsidiary entrepreneurship.

Purpose - This study empirically analyzes the impact of the internal and external network embeddedness of foreign subsidiaries and local market characteristics of the host country on the CEO selection whether or not to appoint an expatriate as the CEO of a foreign subsidiary. Design/methodology - To conduct an empirical analysis, we obtained a list of the headquarters of Korean MNCs from the Korea Chamber of Commerce and Industry. Based on the list of HQs, we identified a final list of overseas subsidiaries of Korean MNCs that have entered the world from KOTRA (Trade-Investment Promotion Agency for Korea). Then we conducted an empirical analysis based on the results of 391 questionnaires by employing logistic regression analysis. Findings - The results of empirical analysis are as follows. First, the higher the subsidiary's internal network embeddedness, the higher the tendency appoint an expatriate as the CEO. Second, the higher the volatility of the local market, the higher the tendency to appoint an expatriate as the CEO. Third, the stronger the competition in the local market, the lower the tendency to appoint a PCN. Originality/value - This study has significant theoretical implications in that it examines the link between the internal and external embeddedness of overseas subsidiaries and the appointment of parent country nationals (PCNs) as the CEO that prior research has not examined.
