This study attempted to extract a suggestive point to help the design of a program, which is used to promote physical activities, by applying a social cognitive theory based on literature review on the physical activity based on a social cognitive theory. This study considers 10 journal articles that used a social cognitive theory, physical activity, and exercise as the major variable using the EBSCOhost Academic Search Premier and Educator's Reference Desk (ERIC). The type of papers was analyzed using a certain criterion, which can be configured according to the number of each year's papers, characteristics of research subjects, application type of a social cognitive theory, and classification of the application of objects in a social cognitive theory. The characteristics of each year's papers presented no specific characteristics for each year's papers, but the study in 2004 especially presented a high level. The characteristics of research subjects presented four highest cases in the case of the college student, and there were zero cases for children. The application type of studies on physical activities using a social cognitive theory can be largely classified as three types. The results of the measurement using a sectional investigation for SCT objects were 2 cases, the application of SCT for promoting physical activities was 1 case, and the demonstration of evaluation for the effect of SCT objects presented 8 highest cases. Although the social cognitive theory in the characteristics of the classification of object applications can be classified as 10 objects, there were no cases that used 10 all objects, partial applications of the object were measured in 8 studies, and two cases presented no detailed considerations on the object. Most of studies used a part of the object where the application of self-efficacy were measured by 8 highest cases. In addition, there were no measurements on the situation, observation learning, answer and response, and self-management. The elements of attitude, cognitive activity, self-efficacy, and handicaps among the SCT object were commonly used, and studies that the self-efficacy largely affects on the promotion of physical activities presented the main current.

Method : We made the internet search with the key words of bee venom(bee venom therapy, apitoxin, apitherapy, bee sting, bee sting therapy), acupuncture, prostate, prostatitis, prostrate cancer in Pubmed, from June 1st to July 1st,2004. Results : 1.25 papers were found in 19 publised jounals. of which two named'Urology'and Prostate' had three papars, two called 'JUrology' and 'Cancer Immunol Immunother' had two papers, and the others had a paper respectively. 2. In the classification by papers' types, Review papers were 8 and Original were 17 where there were 5 clinical trials, 11 experimental studies and 1 epidemiologic paper. Of 5 clinical trials, 2 belonged to Randomized Control Study, and of 11 experimental studies, 4 belonged to in vitro and 7 belonged to in vivo with in viro studies, and 1 epidemeologic belonged to meta-analysis. 3. In the classification by prostate diseases, 4 were about prostatitis, 3 were about prostate related symptoms, 16 were about prostate cancer, and two were about the others. 4. In the classification by applied treatment methods, 5 were related with Acupuncture, 10 were related with BVA(Bee Venom, Bee), and 10 were related with the others. Of 5 related with Acupuncture, 3 used general acupuncture, 1 used electrical acupuncture, and 1 used general acupuncture and electrical acupuncture at the same time. 5. In 2 RCTs of Clinical trials, Control group was set up to the group using different compatible treatment method or using meridians not related with treating prostate disease. Single or double blind methods couldn't be found. 6. In the clinical trials, IPSS, NIH, CPSI or subjective global assessment were used as the Index of Evaluation. 7. The Leg Greater Yang Bladder Meridian(B), The Leg Lesser Um Kidney Meridian(K) and Conception Vessel Meridian(CV) were used as major meridians, and B10(Taejo, Dazhu), B23(Shinsu, Shenshu), B28(Panggwangsu, Pangguangshu), B35(Hoeyang, Huiyang), B39(Wiyang, Weiyang), B40(Wijung, Weizhong), B54(chilbyon, Zhibian), K1(Yongchon, Yongquan), K10(Umgok, Yingu), CV3(Chungguk, Zhongji), CV4(Kwanwon, Guanyuan),S6(Hyopko, Jiache) were used as acupoints. Electrical acupuncture(EA) was considered to be more important and CV3(Chungguk, Zhongji), CV4(Kwanwon, Guanyuan) were mainly selected as EA applied acupoints. 8. It is mostly said that Acupuncture appeared to be a safe, effective, and durable treatment alternative in improving symptoms of patients with prostate diseases, refractory to conventional medicine. A larger controlled study was required to confirm these encouraging initial results. Conclusion : Papers about BVA of Prostate cancer or Prostatitis were not found, and low permeability of Prostate is concerned, BVA with the anti-inflammatory and anti-cancer effect can be adopted as a new alternatives of Prostate disease treatment, so it is thought that Study of how to make access to prostate, animal experiment including in vivo and in vitro and more clinical trials with using acupoints on related meridian should be followed.

Because protein is a primary element responsible for biological or biochemical roles in living bodies, protein function is the core and basis information for biomedical studies. However, recent advances in bio technologies have created an explosive increase in the amount of published literature; therefore, biomedical researchers have a hard time finding needed protein function information. In this paper, a classification system for biomedical literature providing protein function evidence is proposed. Note that, despite our best efforts, we have been unable to find previous studies on the proposed issue. To classify papers based on protein function evidence, we should consider whether the main claim of a paper is to assert a protein function. We, therefore, propose two novel features - protein and assertion. Our experimental results show a classification performance with 71.89% precision, 90.0% recall, and a 79.94% F-measure. In addition, to verify the usefulness of the proposed classification system, two case study applications are investigated - information retrieval for protein function and automatic summarization for protein function text. It is shown that the proposed classification system can be successfully applied to these applications.

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.

The purpose of this study is to provide the valuable basic information that helps set the advanced direction of study in environmental pollution in the future. It classifies and analyzes 6, 531 papers according to their years, fields, and contents from 1962 to 1993 in Korea through Chunrian, a PC communication network, National Environment Research Institute(1989) in Seoul. Classifying papers by their fields, this study shows 19.6%(1, 281 papers) of total papers on water pollution, on which most emphasis was placed in the studies, 17.2%(1, 121 papers) on general remarks, 14.6%(952 papers) on environmental ecology, and 13.6%(891 papers) on air pollution. Classifying papers by their contents, this study tells us that the survey of state and evaluation of pollution degree took 28%(1, 829 papers) of total papers, and it seemed the most active study was carried out on this content. It then shows us that the treatment technology and mechanism shared 17.5%(1, 144 papers), and facilities and design took 1.9%(127 papers) which needed more studies in the future. As for the trends of study, the papers published until 1979 show that the water pollution accounted for 28.9% of total studies, on which the greatest emphasis was placed, while the papers in 1990s tell us that general remarks 34.7%, air pollution 14.9%, and water pollution 14.1%. It also shows that treatment technology and mechanism has had more importance since 1980s in water pollution, noise and vibration, waste materials, human wastes, and radioactive pollution. However, in sea pollution, policy and standard rather than treatment technology or method of measurement and analysis has been considered a more important one in 1990s. Analyzing the studies on general remarks, it tell us that the paper on environmental act, which were frequently conducted, accounted for 33.3% until 1979, while the papers on the environmental policy, in which the highest interest was kept, accounted 34.6% in 1990s. This study concludes that most papers had examined the survey on status and evaluation of pollution degree before 1980, while studies on solving the problems of environmental pollution have had more importance in the 1980s and 1990s. Therefore, in the future, more studies should be conducted actively on policy development to solve the problems of environment pollution as well as on encouragement of environmental consciousness.

Objectives The purpose of this study was to identify the research trends and major fields of Sasang Constitutional Medicine by analyzing the topics of papers contained in the Journal of Sasang Constitutional Medicine from the first issue to 2018. Methods To classify the research themes of the paper, theory, Characteristics in Sasang Constitution(SC), Diagnosis in SC, Treatment in SC, etc. categories and subcategories were created. Two researchers reviewed the title, abstract, and text of the paper and classified them according to the category classification. In case of disagreement, the category was determined through discussion with one of the remaining researchers. Results & Conclusions A total of 1,169 papers published in the Journal of Sasang Constitutional Medicine from the first issue to 2018. The number of published papers has increased steadily since the first issue of the Journal of Sasang Constitutional Medicine, and in 2008, the largest number of papers were published, but since then, the number of papers has gradually decreased. When classifying the categories of published papers according to research themes, the Theory field occupied a large portion in the early stages, but since then, the proportion has decreased steadily, and the number of publications has plummeted since 2012. On the other hand, in Treatment in SC field, its proportion has soared to account for about half of the papers since 2001. In Characteristics in SC and Diagnosis in SC fields, since the early 1990s, the number of publications has been consistently maintained.
