In this study, 3,301 domestic and foreign patents, established from 1980 to June, 2007, were reviewed in order to examine the technological trends in treating or preventing liver disease. Primary focus was placed on countries such as Korea, Japan, and the United States - the leading nations with regard to liver function research. This paper explores the systematic search that utilized a research-focused database and research analysts. Since the year 2000, Korea has demonstrated increased developments in the area of diet and liver disease, as shown by an increase in relevant patent caseloads and submissions especially for medicinal preparations containing compounds or reaction products with undetermined constitutions. In addition, there was up to a 29% increase in themarket share and the frequency of patent submissionshad increased. Japan has shown a similar trend to Korea with an increase in research, but has focused more on medical preparations containing active organic ingredients. In the United States, an increase in the number of patents was shown after the year 2000.

A technological trend of treating or preventing the cardiovascular diseases has reviewed on 381 domestic and foreign patents from the year 1980 to June, 2007. Primarily focused upon countries such as Korea, Japan and the United States; the leading nations concerning cardiovascular disease, this paper delved into a systematic research of the cardiovascular disease utilizing research focused database and research analysts. Korea was showing increased development in the diet and cardiovascular related areas as shown by increase in related patent caseloads and submission since the 2000. Especially within the area of food production, there had been an increase of market share by up to 50% and the frequency of patent submission had also increased. Japan was showing similar trend as Korea with its increase in research, but the only difference was that Japan was focused more upon medical supplies. With the United States, there was no real consistency with the number of patents, therefore harder to make an accurate assessment.

This research entailed collecting domestic and overseas research papers on technologies for fermentation of Kimchi, which is widely considered the national dish of Korea, creating a technology classification structure and conducting quantitative analysis on each technology component and schematization. Five research papers were published in domestic journals in 1990. Afterwards, the number increased by six to nine papers a year. There was no clear increase after the year 2000, but an average of around 20 papers have been Published every year, indicating that Kimchi research is now becoming widespread. An analysis on researchers entailed determining the percentage of research papers published by the top ten authors. The percentage was 76% in the early-1990s; 63% in the late-1990s; and 52% in the 2000s, indicating that Kimchi has been more and more widely researched and Kimchi research has become professionalized. Universities were found to be leading the research as 52% of researchers belonged to universities. Another 9% were at research institutions. Analysis of technologies showed that domestic research mainly focused on the Kimchi fermentation process and an additive for the development of new Kimchi ingredients and types, preservation and quality improvements. Most of the research papers published overseas dealt with the functions of bacteria strains isolated from Kimchi; and improvements in the Kimchi fermentation and ripening processes. And most of the research papers have been published in a field of microorganism and biotechnology.

This is an interdisciplinary study based on Library and Information Science and English Education through the examination of scholarly communication on English education objectively. For this study, three scholarly journals English Teaching, Journal of The Applied Linguistics Association of Korea, and Foreign Languages Education were selected through surveys. A total of 1,091 research articles were analyzed in terms of the pattern of article production and writers, research topics, research methodologies, and research participants. Content analysis was performed to clarify the distinction between these three journals. The results showed that topics on language skills were the most examined out of the 16 categories in ET and FLE. On the other hand, topics on SLA ranked first in AL. In terms of methodology, quantitative research was conducted more frequently than qualitative and mixed methods research from the three journals. And in terms of participants, college students, including graduate students ranked first from the three journals. The findings suggest that scholarly communication needs to be extended to a broader context including students, classroom teachers and more researchers from the public and private sectors.

The R&D investment of Korean government has been concentrated into 6T areas-IT(Information Technology), BT(BIO-Technology), NT(Nano Technology), ET(Environment & Energy Technology), ST(Space Technology) and CT(Culture & Contents Technology) - for a couple

This study is to investigate the trend of researches on food and culture from 1990 to 2003. With a literary approach, this paper analyzes how many papers were published and what was the major research subject. We classified the journals published during this time into 10 different categories and we are to grasp a research trend. 1) Historical approach on the traditional food and food habit; 2) Globalization of Koran food; 3) Use and preparation for traditional food; 4) Table setting and table manner; 5) Provincial cuisine; 6) Traditional festive food or celebratory meal; 7) Religious food; 8) Fusion food; 9) Food and culture in foreign countries and food habit of Korean people living abroad; 10) Studies related with satins out. It was revealed that 268 papers(=ps) were published. Eating out was the most frequently reported subject(100 ps), followed by provincial cuisine(54 ps), use and preparation for traditional food(49 ps), food habit for foreign people and Korean people living abroad(22 ps). Researches on these 4 topics have been accelerated since the late half of 1990s. This reflects the social factors such as rapid growth of food service industry, settlement of local autonomy, popularization of leisure activities and accelerated introduction of foreign food and culture. Half of the studies on the eating out dealt with eating out behavior. And 30 papers were reports on the food service industry situations. More than half of the studies on the provincial cuisine(26 ps) were concentrated on digging out recipes. Studies on the use and preparation for traditional food were mainly about what kind of food and how often the food is used(17 ps). Kimchi was the most frequently studied food. There were 11 papers regarding food and culture in foreign countries. Most of the authors were historians or linguists. Food habit of Korean people living abroad were investigated in 7 papers. There was few studies on fusion food, table setting and table manner. This doesn't meet with increasing demand for specialized information in then fields. Researches on the traditional festive food or celebratory meal(5 ps) and religious food(9 ps) were negligible. Papers on the historical approach to the traditional food and food habit were limited(12 ps). Moreover, most of them were patchwork of existing literatures. Continuous researches to exploit the historical facts based on literary proof should be tried with patience. Otherwise, the papers will copy the hackneyed knowledge repeatedly. Globalization of Korean food means the development of Korean food for foreign people and export of them worldwide. Only 16 papers were reported on this subject, 14 of them were published after 2000, 8 of them were surveys on the foreigners' food preference. In order to get practical informations on what we develope and how we sell for the foreign customers, profound research on their food habit should be done.

인공피부 관련 기술은 1980년대에서는 혈액이나 생체 이식에 적합한 필터/붕대/패드/기타 피복용품의 제조기술(A6IF)에 속하는 것으로 모 또는 피부이식기술 분류(A6IF-002/10)가 주요 연구과제로 진행되어 오다가 1990년대 이후에는 보철 또는 보철물을 피복 또는 코팅을 위한 소재분류(A6IL-027/00)로 전환되어 현재에 이르고 있다. 이것은 초기 피부이식 자체의 외과적인 처리기술에 필요한 기술로 시작되어 점차 소재기술로 큰 전환점을 맞이하였고, 즘 더 나아가서 세포 및 조직 배양기술 (Cl2N-005/00, Cl2N-005/06)의 접목으로 고도화되고 있다는 것을 확인할 수 있다. 전반적인 기술적 수준은 미국이 가장 앞서 있으며, 유럽, 일본, 한국의 상황은 북미 지역에 비해 약간 뒤지고 있으나, 세포를 배양하는 기술적인 수준의 차이는 크지 않다고 보여지며, 아직도 배양피부의 색상, 항균성, 생체적합성 등에서 개선의 과제가 남아 있다고 보여진다 따라서 부작용 가능성 해소, 보급 확대를 위한 제품생산 코스트 인하, 대량생산 시스템 구축, 제품인식도 제고 등이 필요한 것으로 파악되고 있다.

Currently, Ministry of Environment has promulgated and executed 'the legislation of indoor air quality for public facilities' but the data of indoor air pollutant for public facilities of this law was very insufficient. Therefore, collection of data for indoor air pollutants and execution for risk assessment in order to offer scientific data for decision-making of policy to present reasonable standards and preventive techniques of engineering were required. Therefore, this study collected and re-analysed the articles of exposure assessment for indoor environment in journals related environment in Korea since 1990 and estimated the safety factor on residents in public facilities. The objective of this study was to offer scientific data for decision-making of policy for improvement and management of indoor air quality in Korea. As the results of this study, the risk assessment for the critical pollutants in CTE (central tendency exposure) showed that safety factors according to pollutants were less than 1 which means safe level in micro-environments. It was investigated that the safety factors of CO in hospital, NO2 in terminal, PM10 and NO2 in subway station respectively were over than 1 in RME (reasonable maximum exposure). Through the results, it was investigated that health risk by inhalation of criteria and guideline air pollutants in domestic public facilities was not high. It should be considered effect of inhalation by other hazardous air pollutants because this study was examined just partial pollutants. Presentation of scientific data for expansion of study is requisite and active research of health risk assessment about indoor air quality.

이 연구는 1991년부터 2003년까지 발간된 〈교정연구〉에 실린 논문에 대한 내용분석을 통해서 교정학의 연구영역과 연구동향에 관한 논의를 하고 있다. 총 207편의 논문을 분석의 대상으로 하여 연구주제와 연구방법론적 특성과 경향을 밝혀내고 있다. 그 주요 결과를 보면 먼저, 연구주제는 행형관련 주제에 국한되지 않고 상당히 다양했으나, 주제별로 상대적 중요도는 달랐다. 교정행정과 수용자관리, 그리고 교정처우의 법률적, 제도적인 논의는 풍부한 반면 교정의 다른 축인 수용자의 일상생활이나 독특한 문화를 이해하는 논의, 그리고 교정 프로그램의 실질적 효과를 측정하는 효과분석 논문은 양적으로 상당히 미미한 수준이었다. 한편 연구주제에 접근하는 방식인 방법론에 있어서는 대부분이 기술(description)수준의 문헌연구였으며, 실증연구인 경우에도 추론적 통계(inferential statistics)보다는 기술통계(descriptive statistics)를 제시하는 수준에 머물러 있었다. 이러한 결과를 바탕으로 보다 교정학의 발전을 위해 더 관심이 주어져야 할 주제와 방법론적 향상을 위한 제언을 제시하고 있다.
