This study aims to examine the effect that the degree of knowledge about country-of-origin labeling on country-of-origin labeling work performance, which is a culinary staff task. This study is also intended to analyze differences in knowledge depending on hours of origin labeling education, and the moderating effect of education hours in the relationship between knowledge and performance. This study targeted culinary staff members working in ten five-star hotels in Seoul. A total of 205 self-administered questionnaires were distributed from November 14th to 27th, 2014, and 240 questionnaires(98.4%) were used for analysis after the exclusion of 4 with unreliable responses. Based on the data collected, frequency analysis, reliability test, exploratory factor analysis, simple regression analysis, t-test and moderating regression analysis were conducted using SPSS 18.0 program. The study findings are as follows. Culinary staff knowledge of origin labeling had a significantly positive effect on job performance and the degree of knowledge was higher in the group that attended one to two-hour periods of education. This suggests a differences in knowledge depending on the hours of education, which then had a moderating effect on the relationship between knowledge and performance. In conclusion, in order to improve knowledge of country-of-origin labeling and the level of performance, there is a need to increase education hours and enable culinary staff memebers to learn more knowledge and apply it to actual tasks.

Purpose - Southeast Asia has been the focus of Korea's foreign investment. Korea has been helping developing countries in Southeast Asia achieve economic growth and win-win cooperation through capital exports. FDI is an important channel for technology diffusion. However, the impact of FDI on the bias of technological progress in the host country is dependent on the host country's own endowment structure and capital-labor factor substitution elasticity. Therefore, the central issue of this paper is to accurately evaluate the impact of Korea's FDI to the four Southeast Asian countries in various industries on their bias of technological progress. Design/methodology - The paper uses macroeconomic data for Korea and four East Asian countries to estimate capital-labor factor elasticities of substitution using nonlinear, seemingly uncorrelated regressions (NLSUR). Then, the biased technological change index (BTCI) is calculated for each country. Finally, panel data analysis is used to explore the impact of Korean FDI in various industries in the four Southeast Asian countries on their own directed technological progress, and a robustness test is conducted. Findings - There is a substitution relationship between capital and labor factors based on their elasticity in Korea, Singapore and the Philippines. There is a complementary relationship between capital and labor factors in Indonesia and Malaysia. According to the BTCI, there is a trend toward labor-biased technological progress in all countries. Korean investments in manufacturing, wholesale and retail trade in the host country trigger capital-biased technological change in the host country; investments in the finance, insurance and information and communication sectors trigger labor-biased technological change. In addition, this paper also confirms that directed technological progress can enable cross-country transmission. Originality/value - The innovation of this paper lies in three aspects. First, we estimate the BTCI for five countries and explore the trend and situation of directed technological progress in each country from each country's own perspective. Second, we explore the impact of Korean FDI in the host country on the bias to its technological progress at the industry level. Second, we explore the impact of Korean FDI in various industries in the four Southeast Asian countries on the four countries' own directed technological progress from a national perspective. Finally, we propose corresponding countermeasures for technological progress from the perspective of inverse factor endowment. These innovative points not only expand the understanding of technological progress and cross-country technology transfer in East Asia but also provide practical references for policy-makers and business operators.

Purpose - The purpose of this study was to explore the model that supports the recipient country by using the ODA (Official Development Assistance) project and at the same time fits the global start-up/employment support of donor country with CSV business model. Specifically, we wanted to examine the feasibility of the project based on the existing ODA projects. Research design, data, and methodology - As the methodology, case studies and interview were conducted as well as literature studies. The case analysis is based on a press release of the entire KOICA's ODA project, which has been implemented for one year, based on 2017. After consideration, the actual results and future feasibility were analyzed. The interviews were conducted on senior Korean officials and Indian officials involved in Vietnam's ODA project. Results - As a result, some of the project cases applied and analyzed according to the model of this study were judged to be highly potential. Based on the results of this analysis, as the model derived from this study pursues, the global business model is developed under the CSV (Creating Shared Value) strategy through ODA projects to support recipient countries and global start-up/employment support of donor country. The possibility of simultaneously pursuing this model based on CSV business model was also confirmed. Conclusions - In the past, free aid agencies like KOICA focused solely on supporting recipient countries, but in terms of sustainability, they could discover the potential of supporting the global start-up/employment of the donor country using CSV business model in ODA project. In this study, we tried to find the theoretical background and potential possibilities in some ODA projects based on CSV business model. As a result of the analysis of KOICA ODA projects in 2017 and interviews, some ODA projects could be used to improve the economic development of the recipient country as well as the global start-up/employment of the donor country. Therefore, it is necessary for the ministries of the government to promote ODA projects to understand the framework that achieves these two objectives simultaneously and to promote ODA projects based on various strategic considerations.

This paper describes the characteristics and outline of rules of origin among Korea and USA, EU, ASEAN. The main focus of this paper is to conduct comparative analysis on rules of origin. Rules of origin are used to determine the country of origin of a product for purposes of international trade. There are two common types of rules of origin depending upon application, the preferential and non-preferential rules of origin Non-preferential rules of origin are used to determine the country of origin for certain purposes. The basis for the non-preferential rules originates from the Kyoto convention which states that if a product is wholly obtained or produced completely within one country the product shall be deemed having origin in that country. For a product which has been produced in more than one country, the product shall be determined to have origin in the country where the last substantial transformation took place. To determine exactly what was the last substantial transformation, three general rules are applied : Change of tariff classification(on any level, though 4-digit level is the most common), Value added-rule.(ad-valorem), and Specific process rule. While criteria of wholly obtained or produced in one country is almost similar to those of theses area and countries, in compliance with value percentages of Substantial Transformation, sufficient working or processing, Korea-US FTA adapts 'Regional Value Content', meanwhile Korea-EU FTA adapts 'Import Content' rule. Finally, Korea-US FTA and ASEAN FTA adapt FOB price for the calculation value added, on the other hand Korea-EU FTA adapts EXW price.

This study aims to illustrate the national images of United Kingdom, France, and Germany based on the descriptions in the Korean middle school Social Studies textbooks in comparative perspective. In order to identify and compare the national images of the three countries, the author uses a framework for analysis consisting cognitive, normative, and relational factors. The main findings are as follows. First, the most frequently shown topics and issues are democratic institutions in the case of United Kingdom, respect for human rights in the case of France, and sustainable environment in the case of Germany. Second, for all the three countries, the most frequent factor among the three is cognitive one, followed by normative and then relational factors. Third, United Kingdom is described as a country of social unrest and conflict as well as a democratic country with long history and tradition. Fourth, France is described as a country of respect/abuse of human rights, potential for high tech industry, and largest agricultural state in Europe. Fifth, Germany is described more as a country of a leading country for global environmental protection than as a country with electronic and information technology.

Objectives : This study was to suggest the basic data to develop the national exam contents for dental hygiene by comparing with those of other country. Methods : Several dental hygiene education course results were reviewed, and analyzed the culture subjects, basic major subjects, educational subjects, national exam contents in 3 or 4 years dental hygiene curriculum. Results : In Korea, grades of culture subjects in dental hygiene curriculum were different between 3 and 4 years education course, mean grades were 10.4, and 34.5 respectively. While there were few different between 3 and 4 years education course, mean grades were 36, and 36.5 respectively in foreign country. In Korea, grades of major subjects in dental hygiene curriculum were similar between 3 and 4 years education course as mean grades of 110, while there were different between 3 and 4 years education course, mean grades were 60 and 80 respectively in foreign country. In Korea, number of major subject was higher in 4 years(n=61) than 3 years(n=54). However, it was lower in 4 years(n=27) than in 3 years(n=33) in foreign country. Total grade number was 129 in 3 years, and 145 in 4 years in Korea, while it was 97 in 3 years, and 116 in 4 years in foreign country. By analyzing 3 years education course, culture subject was 9.5%, basic health was 11.2%, oral biology was 11.2%, clinical dentistry was 20.7%, public oral health was 10.4%, oral hygiene care was 35.9%, management of dental clinic was 9.4%, education was 2.8% in Korea. In USA, dental hygiene examination contains practice work as major part, while theory was thought of as most important things in korea. Conclusions : It is necessary to improve learning course of dental hygiene curriculum on the basis of other country's system, and then it could be possible to development of good quality's national examination contents, thus good quality of dental hygiene personnel would be turned out in Korea.
