Purpose - This paper examines the effectiveness of the duty drawback system in the promotion of export in Korea In particular, this study analyzes and compares the effects of individual drawback and simplified fixed drawback types of duty drawback. Design/methodology/approach - The empirical analysis examined how the simplified fixed drawback and the individual drawback of duty drawback affected export supply. To analyze the independent variable, an export supply equation was formed using variables such as values of duty drawback, export relative price, and domestic demand pressure. The study began with tests of the stationarity of time series data. The unit root tests showed that all concerned variables were non-stationary. Accordingly, the result of cointegration test showed that the tested variables are not cointegrated. Findings - The empirical evidence using the first differenced data shows that the provision of individual drawback and simplified fixed drawback types of duty drawback by the government does have a significant effect on increasing the export supply of Korea. In other words, the empirical evidence shows that the duty drawback scheme of Korea contributes to export promotion. Research implications or Originality - The analysis of the effect of export promotion by type of drawback is a research topic that has not been attempted in previous studies. The results of this study will provide sufficient basis for the policy implications in the operation of the duty drawback system. Therefore, this study can provide important policy implications in terms of export promotion and efficient allocation of resources, as well as improving the system of duty drawback system, which is an exceptional export subsidy system that can be legally operated under the WTO system.

The life and astronomical activity of Lee Deok-Seong (李德星, 1720-1794) was studied using various historical sources, including the astronomical almanac, Seungjeongwon-Ilgi (Daily records of Royal Secretariat of Joseon dynasty), and the Gwansang-Gam's logbooks during Joseon dynasty (A.D. 1392-1910). We present the results of the study including the following main findings. First, from the investigation of Lee's family tree, we find that a number of his relatives were also astronomers, notably Samryeok-Gwan (三曆官, the post of calendrical calculation). Second, we find that he took part in the compilation of an annual astronomical almanac over a period of at least 16 years. His major achievements in the astronomy of the Joseon dynasty were to establish a new method of calendar-making calculation and to bring astronomical materials to the Joseon court through a visit to China. The Joseon dynasty enforced the Shixianli (時憲曆, a Chinese calendar made by Adam Shall) in 1654 without fully understanding the calendar. So an astronomer and an envoy were dispatched to China in order to master the intricacies of the calendar and to learn as much of Western science as was available in that time and place. Lee Deok-Seong worked at the Gwansang-Gam (觀象監, Royal Astronomical Bureau) during the reigns of King Yeongjo (英祖) and Jeongjo (正祖). As best as we can ascertain in relation with the calculations in the Shixian calendar, Lee visited China four times. During his trips and interactions, he learned a new method for calendar-making calculations, and introduced many Western-Chinese astronomical books to Joseon academia. Lee greatly improved the accuracy of calendrical calculations, even while simplifying the calculation process. With these achievements, he finally was promoted to the title of Sungrok-Daebu (崇祿大夫), the third highest grade of royal official. In conclusion, history demonstrates that Lee Deok-Seong was one of the most outstanding astronomers in the late-Joseon dynasty.

1. Objective: Gastric Stuffiness (心下?證) in the Soeumin Taeeum symptomatology (少陰人 太陰病) in Sasang Constitutional Medicine shows an interesting evolutionary process. Originally found in the texts of Sanghanlun (傷寒論), the perspectives regarding the symptoms of Gastric Stuffiness were expanded by many medical scholars and Lee Jema. To comprehend the Jema's concept of Taeeum symptomatology and utilize his prescription clinically, it deserves to study on the Gastric Stuffiness in Donguisuseowon (東醫壽世保元). 2. Methods: Many texts including Sanghanlun (傷寒論) and Dongeuibogam (東醫寶鑑) were reviewed in order to track the evolutionary process concerning the symptoms of Gastric Stuffiness. Also, Lee Jema's works including the different versions of Donguisuseowon (東醫壽世保元) were reviewed to examine the development of Lee's concepts regarding the Gastric Stuffiness in the Soeumin Taeeum symptomatology. 3. Results and Conclusions: 1) Most of the previous concepts on Gastric Stuffiness were generally similar to those found in Sanghanlun, especially in that they addressed Yang deficiency of the middle triple energizeer as the central pathogenic process. 2) Lee Jema's views on the epigastric discomfort in the Soeumin Taeeum symptomatology evoloved over time and culminated in the finalized pathology and therapeutics appearing in his last work, the Shinchuk version of Donguisuseowon (東醫壽世保元). 3) 4 kinds of prescription which invented by Lee Jema to treat the Gastric Stuffiness in the Soeumin Taeeum symptomatology can be matched to the prescription of Sanghanlun respectively. However through evolutionary process of Jema's prescriptions, the indication of them expanded: not only to treat Gastric Stuffiness but to diverse symptoms of Soeumin.

The purpose of this study was to surveyed the smoking status and pattern, nicotine dependence and factors associated with smoking and nicotine dependence for high school students in Daegu. In March. 2000, 1,593 students from 7 male and 6 female high schools located in Taegu were assessed with self-completing questionnaire. The major findings were as follows; Percentage of male smokers was 15.0% in general high school, 30.9% in business high school and that of female smokers was 5.0% in whole woman's high school. The median score of FTQ was 4.0 among male smokers and female smokers. the mean of FTQ score was 4.07±1.96 in male and 3.94±1.63 in female. Percentage of students with high FTQ score(FTQ≥7) was 13.3% in male and 5.9% in female. In multiple logistic regression analysis, smoking had significant association with general characteristics such as personal-specifics factors, family environment factors and school environment factors. In multiple logistic regression analysis, nicotine dependence had significant association with school-age and duration of smoking. On consideration of above findings, to prevent students from smoking and to reduce the smoking rate, we have to try together in house, school and society.

Postweaning multisystemic wasting syndrome (PMWS) is a new emerging disease in swine herds world wide, and porcine circovirus type 2 (PCV2) is known as a major cause of PMWS. In this study, the prevalence of PCV2 Rep gene was examined for the serum, nasal swabs and feces collected from 30 heads of piglets affected with PMWS and 10 heads of normal healthy piglets using polymerase chain reaction (PCR). The diagnostic efficiency of the PCR was evaluated for different types of samples. Rep gene of the isolate (PCV2 S1) was then sequenced. In the group of PMWS-affected piglets, the prevalence of PCR-positive were 70.0% in sera, 33.3% in nasal swabs and 0% in feces. In the normal healthy group, the PCR-positive rates of sera, nasal swabs and feces were 30%, 20% and 0%, respectively. Seven piglets (17.5%) out of 40 showed the simultaneously positive results in both of sera and nasal swabs. The nucleotide sequence homology of Rep gene of PCV2 S1 as compared with the reference strain of PCV2 (GenBank accesson no.AF027217) was 99.3%.
