  • 천수방정식 형태의 쌍곡선형 완경사 방정식을 이용하여 파랑의 반사파 성분을 분해하는 방법을 제시한다. 모델의 반사파 산정능력을 평가하기 위하여 Booij 경사면 및 물결사주에 적용한다. Chamberlain and Porter(1995)에 의하여 주어진 수심경사제곱항과 수심곡률항의 효과를 포함하였을 때 Berkhoff의 완경사 방정식에 의한 결과보다 유한요소법 결과나 실험 자료와 비교하여 훨씬 만족할 만한 결과를 보여주었다.

  • The LNG tank are properly designed to fit with the limited installation space of a light duty truck, Hyundai Porter II. This designed LNG tank has 36 liter capacity, so two LNG tanks installed on Porter II truck allow it to run about 432 km per fueling. It is almost two times greater than CNG mileage for same truck. To analyze the relationship between car acceleration and heat leak for different fuel vapor/liquid ratios, the modified Fortran program "Pro-Heatleak" is used. Computational analysis shows that the relationship between the heat leak and vapor/liquid ratio is linearly inversed. Heat leak increases with increasing of car acceleration when fuel vapor/liquid ratio is less than 0.5 and decreases when fuel vapor/liquid ratio is greater than 0.5. The difference between maximum and minimum heat leak for full tank is about 12 percents. For the fuel vapor/liquid ratio equal to 0.5 heat leak does not depend on car acceleration.

  • The overall objective of this article is to identify the strategic type of Korean hospitals in terms of Porter's framework and to examine differences in performance of the hospitals across strategic types. A survey was conducted through structured questionnaire for 739 hospitals in Korea and the data from 120 hospitals were utilized in the final analysis. Study results indicate that the most frequently used strategy was 'stuck-in-the-middle strategy'(26.7%), followed by 'focused cost leadership strategy'(24.0%), 'focused differentiation strategy'(20.8%), 'cost leadership strategy'(15.8%), and 'differentiation strategy'(13.7%). Overall, 'focused differentiation strategy' showed superior performance in terms of profitability of services, ability to retain patients and growth in revenue, while 'differentiation strategy' produced relatively low performance in general. Implications of these findings are also discussed.

  • 농식품 수출활성화는 국내농업의 소득창출을 위한 새로운 전환기를 제공하는 방안이라는 인식이 확산되고 있다. 최근 한류열풍으로 국내 농식품에 대한 인식이 확산됨에 따라 농식품 수출은 새로운 도전이면서 기회이기도 하다. 그러나 국내 농업이 가지고 있는 구조적 문제와 수출시장 진입에 관한 중장기적 전략부재로 인해 수출시장 경쟁력이 향상되지 못하고 있는 설정이다. 이러한 환경 하에서 본 연구는 우리나라 수출농업 활성화를 위해 농식품 수출부문의 경쟁력을 제고시킬 수 있는 포괄적인 접근의 필요성을 인식하고 농식품 수출분야에 경쟁력의 개념을 도입하여 농식품의 수출정쟁력 결정요인에 대하여 분석하였다. 농식품 수출부문의 국가 경쟁력 비교분석을 위해서는 종합적인 시각에서 농식품 수출부문을 분석 할 수 있는 평가모델과 측정척도를 적용하는 것이 중요하다. 따라서 비농업분야에서 경쟁력 결정요인을 찾기 위해 다양하게 적용된 포터의 경쟁력 모델을 중심으로 농식품 수출부문의 경쟁력을 비교분석하였다. 이를 바탕으로 우리나라의 농식품 수출부문의 국가경쟁력 강화방안을 모색하고자 한다.

  • Fashion magazine advertising is the most excellent source of information in predicting the fashion trend. It plays a pivotal role in setting a direction for the fashion trend in the upcoming season. The purpose of this study was to review by photos of the $pr{\hat{e}}t-{\acute{a}}-porter$ collection shown in LONDON, NEW YORK, MILAN, and PARIS during 2002-2006 A/W and 2003-2005 S/S seasons, being focused on such fashion items published as coat, dress, one-piece, two-pieces(jacket+skirt/pants, blouse+skirt/pants). In the results of this study, designers presented coat(n=144) chiefly, blouse+pants(n=29) were presented few during 2002-2003 A/W seasons. During 2003-2004 A/W seasons one-piece(n=156) was looking bullish, blouse+pants(n=34) were declining. Dress(n=149) was presented mostly, blouse+pants(n=17) was presented few during 2004-2005 A/W seasons. During 2005-2006 A/W seasons coat(n=180) was revived, blouse+pants(n=26) were presented lowly. Therefore designers presented coat(n=605, 28.4%) extremely much during 2002-2006 A/W seasons. Designers presented one-piece(n=109) much, jacket+pants(n=22) were presented few in 2003 S/S. In 2004 S/S seasons one-piece(n=167) was presented vastly different than jacket+pants(n=42). Also one-piece(n=152) was presented mostly, blouse+pants(n=48) was presented few in 2005 S/S seasons. During 2003-2005 S/S seasons one-piece(n=428, 28.2%) was presented most. And designers in these four world fashion centers didn't prefer blouse+pants in A/W seasons and jacket+pants in S/S seasons. Based on the above findings, it could be confirmed that the fashion items trend was almost similar among the four collections of $pr{\hat{e}}t-{\acute{a}}-porter$. The results of this study suggest that the fashion collections are the most reliable information sources for fashion product planning. Lastly, it is hoped that this study will provide for some useful basic data for domestic fashion businesses in producing fashion items.

  • The purpose of this study is to examine the determinants and elements to enhance Korean international competitiveness, employing Porter's(1998) Diamond Model. Half of the 500 leading apparel exporters that were members of the Korea Apparel Industry Association in 2003 were selected as the target of this research. From May to June of 2003, survey questionnaires were sent to executives of these 250 companies in person or by telephone, e-mail, or fax. Seventy questionnaires were used for the final data anlysis. The items used were Reliability, Categorical Regression, and Frequency, using SPSS 11.5. The results were as follows: First, as a result of analyzing the influence of international competitiveness in Korean apparel industry, the firm's strategy, structure, and rivalry was the most influential factor. Others were related and supporting industries, government, chance, demand conditions, and factor conditions. Also, the elements that affect Korean international competitiveness were listed as the level of price competition in foreign markets, the level of labor cost, export marketing capacity, and exchange fluctuation. The most important element to improve the international competitiveness of the Korean apparel industry was a demand growth rate of the overseas markets(Demand Conditions), followed by the level of the labor costs(Factor Conditions), the capability of internationalization(Firm Strategy, Structure, and Rivalry), the change of currency(Chance), the quality and management of products(Demand Conditions), the capability of planning products(Firm Strategy, Structure, and Rivalry), free trade from 2005(Chance), and global sourcing strategy(Firm Strategy, Structure, and Rivalry). Korea's main rival country in apparel related and supporting industry factors is China. However, Korea has a higher level of technology development, quality, and price level than China.
