본 논문은 국제유가 변동이 한국의 제조업 품목별 수출물가에 미치는 비대칭적 영향을 분석했다. 수출의존도가 큰 한국 기업들에게는 국제유가 변동을 수출물가에 얼마나 전가할 수 있는가의 여부가 중요하다. 수출물가에 대한 유가 변동의 전이 정도는 산업별로 다를 것이기 때문에 본 연구에서는 제조업 중 8개 산업의 모형을 각각 추정했다. 분석을 위한 모형으로 비선형 자기시차(Nonlinear Autoregressive Distributed Lag) 모형을 이용했다. 이 모형을 이용 시 국제유가의 상승기와 하락기를 구분하여 장단기 수출물가에 미치는 전이 효과의 차이를 테스트할 수 있다. 국제유가가 상승과 하락 시 모든 품목의 수출물가도 상승과 하락하는 양(+)의 전이효과가 나타났으나, 일부 품목에서는 그 영향이 비대칭적으로 나타났다. 일반기계와 수송장비 등 5개 품목에서는 단기적 비대칭성이 나타났으며, 석유 및 석탄제품과 섬유 및 가죽제품의 경우 단기적 비대칭뿐만 아니라 장기 비대칭이 나타났다. 국제유가가 1% 상승 시 석유 및 석탄제품의 수출단가는 장기적으로 0.992% 상승하나 하락 시에는 수출단가가 0.977% 하락하여 통계적으로 유의한 비대칭성이 있는 것으로 분석되었다. 따라서 이러한 국제유가가 수출물가에 주는 비대칭적 영향을 고려해 기업의 전략과 정부의 수출 정책을 수립해야 할 것이다.

A firm seeking to enter a foreign market must make an important strategic decision of which market entry mode to use. Because entry modes involve resource commitments, the initial choice by a firm on a particular entry mode is difficult to change without a considerable loss of time and money. Substantial prior research has been undertaken to explain why firms select a particular entry mode into global markets. However, there exists limited research on this area in the field of foreign apparel brands in Korea, although some research has analyzed influential entry mode factors when Korean textile and clothing companies went overseas. This study reviews prior research on the entry mode choice and analyzes the factors that influence the entry mode choice for 510 foreign clothing brands in Korea. Price range, clothing types, distribution strategy, and cultural distance were considered as influential determinants for different entry mode choices. Crosstabs with a chi-square test and logistic regression are used for analysis. This study shows that high-priced brands and luxury brands are associated with the export orientated entry mode in the Korean market. Brands that pursued the strategy of multiple distribution channels showed a preference for a licensing mode or direct investment over other entry modes, and brands from higher-cultural-distance countries entered the Korean clothing market by licensing mode. The findings of this study are appropriate for the strategic planning of foreign apparel intent on entering the Korean market or for Korean apparel firms planning to enter the global market.

This study analyzes the status of foreign direct investment in Korean textiles and fashion firms and investigates the factors determining their performance. A total of 1,251 cases (including 1,116 manufacturers and 135 of distributors from the 2009/2010 Korean Overseas Business Directory published by KOTRA) were used. The results of this study are as follow: 1) In the case of manufacturers, China was the most heavily invested in country, and the Asian region that included China, Vietnam, Indonesia and Bangladesh consisted of 80% total investment. In cases of distributors, China was also the first ranking country and other countries, that included Vietnam, United States, and Japan are major ones. 2) In terms of the foreign entry mode, wholly-owned subsidiaries represented 90% of total cases. As the index of the degree of localization, the ratio of local employees was very high. 3) Different countries were utilized by year, type of business, and area of process. In manufacturers, Indonesia, China, and Vietnam were the most heavily utilized countries in the 1980s, 1990s, and 2000s, respectively. For distributors, China was the major market ill the 1980s and 1990s but Vietnam has emerged as the biggest market in the 2000s. In terms of area of process, China was for manufacturing fibers and fabrics, Vietnam was for most items, Indonesia was for assembly, knit, accessories, and Bangladesh was for embroidery and accessories. 4) The determining factors of the age of foreign business as the proxy index and performance of foreign business entry, were different by the type of business. For manufacturers, four factors including the dollar amount of investment, number of local employees, the mode of foreign direct investment, and entry to China were significant. On the other hand, only two factors including the dollar amount of investment and entry (other than China) were significant distributors.

This thesis has three main purposes: first, will show kinds, patterns, types, expression techniques of modern korean women's trimmings by every ten years. Second, it is to trace the effect of each decade on women's Hanbok trimming designs. Third, it will point out factors. that caused the change of modern Korean women's Hanbok trimming design patterns. Henceforth, there comes the result of the research and analysis. Trimming design patterns of modern women's Hanbok can be divided into three categories temporally: The first period of from 1910s to the first half of 1950s saw that design patterns did not changed much from traditional ones. It is because there were many catastrophes such as the invasion of Japanese Empire and Korean War. The compound design had expressed people's wish to earn many sons and babies at the end of Joseon Dynasty. But it turned to wishing luck for individuals affected by individualism and liberalism imported from the west. Realistic designs are the most frequently used and the least lines made up patterns. The second period of from the latter half of 1950s to 1970s saw that women wore their Jeogories and Chimas as suits. Screen printing technique enabled for various design patterns to come out. And the development of textile industry introduced various expression techniques such as making lace, meshing, flocking, burn-out etc cetera. The third period of 1980s saw that Hanbok became a kind of luxurious clothe as people's living standard rose. Hanbok again came into the spotlight, Hanbok designers came forward and their individualities are respected. The characteristic expression technique of grey-dying and geometric design patterns are more frequently used for the simple and modern beauty.

This study was performed to offer the basic data for the design of farm shoes. 265 Korean female farmers aging between the 40s to the 80s volunteered for this study and we measured 40 items on each foot with the 3D foot scanner. First, the differences between farmers' feet and non-farmers' feet were analyzed. Farmers' feet were thicker in the instep areas, but had lower arch height than non-farmers' feet. In addition, farmer's feet were tilted to the inside. Next, eight factors were extracted among the 40 measuring items, and the classification criteria of the foot shape was analyzed. The important factors were: size of foot length and volume of ankle, malleolus height and size, volume of the front part of ankle, medial & lateral ball width, and vertical size of foot. Third, three clusters according to the foot shapes were categorized by cluster analysis of eight factor scores. Foot type 1 was medium in foot length, big in thickness, large in lateral ball width, small in toe 1 angle, and tilted to the inside. Foot type 2 was long and slim, and big in toe 5 angle. Foot type 3 was short in foot length, medium in volume of the front part of ankle, large in medial ball width, and big in toe 1 angle. Despite its shortness, foot type 3 was thick and showed severe deformation in toe 1. Lastly, the frequency distributions of the foot types in each age group were analyzed. Female farmers of the forties showed high frequency in type 1 and other age groups showed high frequency in type 2. The older female farmers showed higher frequency of type 3.
