This study was done to investigate the English vowels in relation to the foreign accent. In this study, I also tried to find out the foreign accent of the English diphthong /o/ and front low vowel /${\ae}$/ when Koreans speak English. The reason why I chose these vowels is that these vowels, /o/ and /${\ae}$/, are difficult for Koreans to discern and pronounce. Koreans show a foreign accent in their pronunciation. In order to find out the reason for a Korean foreign accent, experiments were carried out with the help of acoustic instruments. According to the results of the experiment, Koreans showed a foreign accent in their English pronunciation of vowels in relation to their utterance positions. Americans showed a final lengthening effect but Koreans showed a final shortening effect. This means that Koreans showed a foreign accent in the final stressed syllable of a sentence. In addition to this, the duration of two English vowels, /o/ and /${\ae}$/, showed considerably different features between Koreans and Americans. In fact, in the pronunciation of the diphthong /o/, the tongue moves from one position to another. The two articulations of a diphthong can be described as the nucleus plus a glide. However, most Koreans have no idea of this phenomenon and pronounce the diphthongs like two separate monophthongs. This causes a great difference in the lengths of English diphthong /o/ between Koreans and Americans.

The purpose of this study is to examine level of individual foreign learners' quantitative knowledge of korean vocabulary through the Foreign Learners' Korean Vocabulary Knowledge Assessment and to propose a vocabulary education plan reflecting the result. This assessment was written in focus of semantic relation to identify category, integrated and analytical knowledge of Korean verbs acquired by foreign learners and as a result, the following educational implications were made. First, the learners' knowledge about the vocabulary combinational relationship was very limited. Second, learners are not interested in vocabulary's synonymous relation and antonymous relations. Lastly, there needs to be a concern about postpositional particle-use education. The results of these kinds of research, observes the learners vocabulary acquisition process to determine Korean textbook and present vocabulary level in appropriate in terms of learners' perspective, and provide an opportunity to check if current professors' method is adequate and valid.

With the advent of the globalization trend of the industry, the enterprises in the fashion industry around the world have witnessed a surge in exports and foreign direct investment (FDI). Many fashion enterprises in each country, along with the multi-national enterprises, have engaged in global outsourcing of the production process in order to increase their global competitiveness, and have attempted to expand their commercial presence in the world market by entering into other foreign markets. Such market entry attempts have lead to the increase of FDI and trade by the fashion enterprises. This study attempts to examine the interactive relation between FDI and export/import of fashion products in different fashion industries both worldwide and in Korea. First, we will look into the relation between export/imports and FDI of each regional fashion industry, then expand the study to the relation between those two factors found in the fashion industry of Korea in general, and finally, to the relation between the two factors in the fashion industry of countries that are the major export nations of fashion goods into Korea. The data which this study is based on were collected from the International Trade Statistics Yearbook Vol. II (UN, 1991-2002, New York: UN), UNCTAD Handbook of Statistics (UN, 1996-2001, Vienna: UN), UNCTAD database, the archives of the Korea Federation of Textile Industry and the archives of the Export-Import Bank of Korea. The methods of analysis used in this study were correlation, regression, and descriptive statistics of the data. The result of this study showed that each fashion industry of different regions was subject to a diversity of effects. For one, the fashion industry in Korea showed a significant correlation between outbound investment and both export and import. On the other hand, the apparel industry in Korea showed a significant correlation between outbound investment and imports, but no such correlation between outbound investment and exports.

본 연구에서는 애국심이 자국 및 외국 제품 평가에 미치는 영향을 실증적으로 분석하였다. 또한 애국심과 제품평가 간의 관계에 있어 소비자 자민족중심주의의 매개변수적 영향력을 분석하였다. 실증분석을 위해 서울 소재 대학에 재학 중인 학부생과 대학원생을 대상으로 설문조사를 실시하였다. 조사결과 애국심은 외국제품 평가에는 영향을 미치지 않는 것으로 나타났으나, 자국제품 평가에는 긍정적 영향을 미치는 것으로 나타났다. 또한 소비자 자민족중심주의는 애국심과 자국제품 평가 간의 관계를 매개하는 것으로 나타났다. 실증분석 결과를 토대로 연구의 의의를 논하였으며, 유통관리 측면에서의 시사점을 제시하였다. 끝으로 연구의 한계점과 향후 연구방향을 제안하였다.

본 논문은 우리나라 주식시장과 외환시장의 기대 수익률과 조건부 변동성간의 시계열적 관계를 2요인 자본자산가격결정모형(two-factor ICAPM)을 이용하여 실증 분석하였다. 주가와 환율의 조건부 분산은 GARCH 모형과 비대칭성을 반영한 GJR(1993) 모형으로 추정하였으며, 주가와 환율과의 조건부 공분산은 Bollerslev(1990)의 일정 상관관계(CCC) 모형과 Engle(2002)의 동태적 조건부상관관계(DCC) 모형을 이용하여 추정하였다. 실증 분석모형은 MGARCH-M 모형을 사용하였으며, 추정방법은 준최우추정법(QMLE)을 사용하였다. 실증 분석결과 외환위기 이후에 주식시장의 기대 수익률은 주가의 분산에 대해, 그리고 환율과의 공분산에 대해 유의한 음(-)의 관계를 갖는 것으로 나타났다. 그러나 외환시장에서 기대 수익률은 조건부 분산과 조건부 공분산에 대해 유의하지 않은 것으로 나타났다. 조건부 분산의 추정에서는 GJR 모형이 GARCH 모형에 비해 더 적합한 것으로 나타났다. 그리고 DCC 모형이 CCC 모형에 비해 설명력이 더 높은 것으로 나타났다. 본 논문의 분석결과는 주식시장에서 환율 변동이 위험 요인으로 작용하고 있기 때문에 포트폴리오 구성이나 위험 관리 등에서 환율 변동을 고려할 필요가 있고, 변수들간의 상관관계는 시변하는 모형을 사용할 필요가 있음을 시사한다.

This study suggested ways to control UML diagram and to make design of database and to retrieve diagram information by giving questions. The study classified elements of the diagram. For instance, class diagram was made of classes, and class was done of class name and attribute operator. The elements were transformed to be database table having basic key and foreign key information. The ways suggested had advantages of users' sharing of model information and reuse of the model. This study investigated cost saving, time saving and UML model construction by database. We had designed integrated and relation database that could save and manage UML diagram, and suggested retrieval. For instance, we classified class diagram into elements to make tables and kept relation of each element by using not only basic key of relation database but also foreign key information. We made database of modeling depending upon methods to give users convenience.

This paper examines the results of survey that the foreign ownership is cointegrated with capital market conditions in Korea using Vector Error Correction Model (VECM) and how the mechanism of innovations and dynamics among the foreign ownership and capital market proxies in the VECM was described. Specifically, we find that the foreign ownership and capital market proxies follow I (1) process and there are cointegrated relations between the foreign ownership and capital market proxies. Adopting the impulse response function and variance decomposition in the VECM, we suggest, in turn, the default risk premia, liquidity of market and the rate of interest in long term business cycle take on a special function on the KSE and KOSDAQ. Finally, we also offer evidences of which there are differences of the mechanism of dynamics and innovations between on the KSE and on the KOSDAQ.

The employment permit system for foreigners, which stresses introduction of foreign work force in a legal manner rather than in the position of being trainees, is anticipated to efficiently improve introduction and the overall management system of foreign work force and related difficulties such as illegal alien problems, absurdity on sending laborers overseas. In this paper, a prospective model of supply and demand of work force has been developed basing on various categories of industries and patterns about nationally practical foreign employees to look over efficient supply and demand of work force suiting employment of foreigner among foreign work force policies. To propose the prospective model, we have derived industry- and pattern-related matrixes of foreign laborers basing on Inter-Industry Analysis Method put forth by Professor Leontiyef in 1930, and through the derived matrix assessed repercussions concerning overall domestic industries and foreigner types and decided yearly weight; the capacity of supply and demand of foreign laborers can be compared through proposed statistical estimation and government estimation by combining the determined weight with yearly incomes of foreign laborers. This paper has thoroughly considered the particularity of our employment permit system for foreigners and applied the Weibull distribution and incorporated the dependence of foreign laborers during the limited period of 3 years to the industry relation analysis, ultimately proposing an efficient supply and demand method about domestic foreign work force.
