A Study about the Effect of the Kwang-Dong Qi-Gong Therapy in Bariatrics. The purpose of this study is to find out what effects the practice of Qi-Gong shows in controlling obese that is one of the main causes of adult disease. In this study, the researchers chose some overweight or obese subjects over 17 years and divided them into two groups, and gave 4 weeks of twelve treatments to one group with Kwang-Dong Qi-Gong therapy developed by Hong Seong-Gyun in Kwang-Dong, and did not give any treatment to another group. And the effects were evaluated by comparative analysis. Before and after the treatments, the researchers measured the height, weight, body fat, BMI(Body Mass Index), hip size, etc. of two groups of them. And the health condition and eating habits of each persons of the two groups were examined before the experiment, and the difference of eating habits between the two groups was investigated in the course of the experiment, and the effects of the therapy that the treated group felt is investigated with an questionnaire sheet after the experiment. The following shows the result of the comparative analysis about the experiment 1. The result of the experiment about the effect of Kwang-Dong Qi-Gong therapy treated to control overweight or obese shows that : a) The height, body weight, BMI, body fat index, chest size did not make any statistically meaningful difference. b) The measurements of hip, waist, forearms, thighs, calves, and ankles made meaningful differences. 2. In the course of the experiment, the eating habits of the two groups did not make any significant difference except the frequency of dining together. 3. The effect of Kwang-Dong Qi-Gong therapy for the group that was given 12 treatments shows that : a) Regarding the change of their defecation, 81% of the subjects in the treated group said 'Yes' and 19% said 'No', that is most of subjects answered positively. b) Before the experiment, three subjects of the treated group had been taking medicine, but after the practice of Kwang-Dong Qi-Gong therapy, they appeared to stop taking medicine. c) 87% of subjects in the treated group said that they 'feel well' after he practice, 13% said that they 'did not feel well', that is most of subjects were satisfied with Kwang-Dong Qi-Gong therapy. d) 81% of subjects in the treated group replied that they 'feel peaceful in mind' after the practice, 19% replied that they 'did not feel peaceful in mind.'

Background: : Familial adenomatous polyposis (FAP) is an autosomal dominant inherited disease mainly caused by mutations of the adenomatous polyposis coli (APC) gene with almost complete penetrance. These colorectal polyps are precancerous lesions that will inevitable develop into colorectal cancer at the median age of 40-year old if total proctocolectomy is not performed. So identification of APC germline mutations has great implications for genetic counseling and management of FAP patients. In this study, we screened APC germline mutations in Chinese FAP patients, in order to find novel mutations and the APC gene germline mutation characteristics of Chinese FAP patients. Materials and Methods: The FAP patients were diagnosed by clinical manifestations, family histories, endoscope and biopsy. Then patients peripheral blood samples were collected, afterwards, genomic DNA was extracted. The mutation analysis of the APC gene was conducted by direct polymerase chain reaction (PCR) sequencing for micromutations and multiplex ligation-dependent probe amplification (MLPA) for large duplications and/or deletions. Results: We found 6 micromutations out of 14 FAP pedigrees, while there were no large duplications and/or deletions found. These germline mutations are c.5432C>T(p. Ser1811Leu), two c.3926_3930delAAAAG (p.Glu1309AspfsX4), c.3921_3924delAAAA (p.Ile1307MetfsX13), c3184_3187delCAAA(p.Gln1061AspfsX59) and c4127_4126delAT (p.Tyr1376LysfsX9), respectively, and all deletion mutations resulted in a premature stop codon. At the same time, we found c.3921_3924delAAAA and two c.3926_3930delAAAAG are located in AAAAG short tandem repeats, c3184_3187delCAAA is located in the CAAA interrupted direct repeats, and c4127_4128 del AT is located in the 5'-CCTGAACA-3', 3'-ACAAGTCC-5 palindromes (inverted repeats) of the APC gene. Furthermore, deletion mutations are mostly located at condon 1309. Conclusions: Though there were no novel mutations found as the pathogenic gene of FAP in this study, we found nucleotide sequence containing short tandem repeats and palindromes (inverted repeats), especially the 5 bp base deletion at codon 1309, are mutations in high incidence area in APC gene,.

Many hidden aspects of society around the world that has been lurking as risk factors have been ultimately connected to disasters. Such connection did not just stop with massive damages to properties and loss of lives but became a serious social issue. Especially in the case for Korea, because the country has gone through abrupt economic growth which has resulted in rapid urbanization and expansion of economic scale, Korea has been caught in a vicious cycle of experiencing human and social calamities repeatedly. Due to the seriousness of such problem, there's been continued research in various fields for managing disasters, and the domain of knowledge has been expanding with complexity. The following study went beyond the perspectives of disaster prevention study, disaster prevention engineering and social sciences suggested from previous research directions in disaster and disaster prevention, and attempted an alternative research method by approaching from a service design perspective. During the process, the paper looked over the summary on disaster and service design. By applying it on disaster prevention projects, the research sets forth and discusses effective and practical disaster prevention service design. Through specific case studies, the research methodology applied was verified, and the purpose of the study was carried out in the perspective of real world applications different from textbook type discussions. It is expected that through the disaster prevention service design process and platform that were discovered during the research result, defining and understanding disaster prevention service design will be made apparent. Additionally, the research is expected to be used as a basic building block for building a visualized plan for tangible and intangible factors related to disasters before the disaster process through such proposed disaster prevention service design.

During the past decades,several automatic indexing systems have been developed such as single term indexing.phrase indexing and thesaurus basedidndexing systems.Among these systems,single term indexing has been known as superior to others despte its simpicity of extracting meaningful terms.On the other hand,thesaurus based one has been conceived as producing low retrival rate ,mainly because thesauri do not usually have enough index terms.so that much of text data fail to be indexed if they do not match with any of index terms in thesauri.This paper develops a thesaurus based indexing system THINS that yields higher retrieval rate than other systems.by doing syntactic analysis of text data and matching them with index terms in thesauri partially.First,the system analyzes the input text syntactically by using the machine translation suystem MATES/EK and extracts noun phrases.After deleting stop words from noun phrases and stemming the remaining ones.it tries to index these with similar index terms in the thesaurus as much as possible. We conduct an experiment with CACM data set that measures the retrieval effectiveness with CACM data set that measures the retrieval effectuvenss of THINS with single term based one under HYKIS-a thesaurus based information retrieval system.It turns out that THINS yields about 10 percent higher precision than single term based one.while shows 8to9 percent lower recall.This retrieval rate shows that THINS improves much better than privious ones that only yields 25 or 30 percent lower precision than single term based one.We also argue that the relatively lower recall is cause by that CRCS-the thesaurus included in CACM datea set is very incomplete one,having only more than one thousand terms,thus THINS is expected to produce much higher rate if it is associated with currently available large thesaurus.

In the field of number and operation of mathematics, a learner's learning deficit in one year can disturb or obstruct his or her learning in the following year, which is an obvious characteristic in math education. But the problem doesn't stop here. It may increase poor learning in the related math field or, in a serious case, cause mathematical learning incompetence. In the other hand, a teacher must guide a class of about 40 students and take charge of overburdensome routine; it's really impossible for him or her to secure individual teaching time for poor learners and to give lessons considering their individual poor learning elements. In order to solve these problems, this study has found out some poor learning elements from poor learners in teaching mathematical number and operation, offered learning fit for them, and allowed them to approach a learning system regardless of time and space. And it has embodied a web-based learning system for operation field underachiever in elementary school, applied it to the scene of education, and analyzed the results so that a teacher may manage their learning results by DB and guide poor learners systematically. As a consequence, the study could reduce a teacher's teaching overburden and at the same time, raise the learning accomplishments of poor learners.

In recent years, changes in the university libraries environment have led to increased emphases on improving or restructuring the organizational structures of university libraries. Technology, trends toward access over ownership, user focus, and restructuring in higher education are some of the major factors contributing to these changes. The users' new information retrieving behavior are emerged from the developments in information technology with new media and from the competitive research environments, and thus this trend has led to the gradual increase of collection arrangement by subjects rather than by forms, particularly from 1995 in Korean universities' libraries. Users especially in university libraries who are frequently seeking information on the specific subject, are going to find a room accoinmodating all forms of information on the subject, that is, one-stop information service. As a result, subject division structure have adopted as a new organizational structure in Korea. Our survey shows 34 out of 73 university libraries in Korea is taking this structure of which collections are arranged by subjects, while the rest of them are operating with a traditional organizational structure by forms focusing on keeping of collection management. In the future, university libraries with traditional organizational structure will be moving towards the subject division structure which is a recommended one by this study.

In order to determine the porosity of rock, the 'standard test method for porosity and density of rock' proposed by the Korean Society for Rock Mechanics is commonly used. However, the standard test method, which uses a drying oven, takes 8 to 24 hours to complete the test in taking samples out of the oven every four hours and measuring the weight of the specimen. To complement these disadvantages, we devised a method for measuring rock porosity by using a microwave oven. The devised method reduced the cause of errors and the inconvenience occurred in the process of weighing samples by constructing a weight monitoring system, which monitors the drying process. A suitable heating/pause time was set up to maintain the temperature of sample below $105{\pm}3^{\circ}C$ in drying process, and an alarm system was implemented in order to stop drying process when the weight change of the rock sample is within 0.1% of the initial weight. The porosity was determined from the dry weight of the sample, which was obtained by the curve fitting of weight monitoring data. Then, the porosities obtained by using the microwave oven were compared with those obtained by the standard test method. Test results using sandstone samples showed that the porosities obtained by a microwave oven was similar to those obtained by the standard method and the porosity difference between two methods was as large as 0.4%. In addition, repeated porosity measurement using the same specimen showed that the standard deviation of the porosity, which reflects the precision of the measurement was as good as 0.23%. Therefore, a microwave oven porosity measurement system can give the porosity of rock samples with high reliability.

Visitors to Naejangsan National Park were surveyed from October 31 to November 3 in 1995, 151 visitors were participated. Of those individuals, 55% were males. 48% of respondests reported that they had gone beyond high school, and over one-half(52%) had gone as far as college. 61.3% were 20 years of age. The largest percentage of respondents were reported that they visited Naejangsan Nat'l Park to see the scarlet maple leaces there. Most respondents who witness other visitors' littering were not likely to intervene to stop their visitors' depreciative behavior(Bystander intervention Begavior). Most of visitors got information for use Naejangsan Nat'l Park from a guide sign(31.8%) or guide themselves(29.1%). They didn't know the Clean-up Time Movement Program. But they understood it after notice hanging placards(81.6%). Most of visitors responded that didn't hear the mass communication program in National. But they recognized necessity of the mass communication program in National Park. The results showed that most visitors believed that Clean-up Time Movement was in succession consequently it turned out to be effective in managing visitors' littering behavior. And it seemed to effective in managing depreciative behavior through the mass communication program in National Park.

This paper is intended to suggest benchmarking ascension for the Gwangyang Port as a hub for international logistics. Most countries that seek to join. and lead, the global trading system as they work to develop production and logistics systems that establish a reputation for leadership in international logistics. Our focus in this research is on the Gwangyang Port and whether Gwangyang Port is capable of carving out a competitive niche as a hub of international logistics. Our analysis is based on comparison and analysis with benchmark port developments around the world. As proposals to promote and activate Gwangyang Port as a hub for international logistics, we recommended in this paper several benchmarks. First, Gwangyang Port FTZ must strengthen the incentive system for tenant companies and providing an inducement for new global companies. Second, Gwangyang Port needs to moderation of regulation on the investment tenant companies and strengthening one-stop service. Third, it is required to stabilize labor and management relationship and securing of flexibility of labor market. Lastly, Gwangyang Port must strengthen mutual interaction of Free Economic Zone (FEZ), Customs Free Zone(CFZ) and Free trade Zone(FTZ) in Korea.
