In this study, web document frequency of city place name is analyzed and it is used as the dataset for rank-size analysis. The search keywords are compared in the context of spatial meaning and the different domain corpus is applied. The acquired search results are applied for the further analysis. Firstly, the rank-size analysis is applied to compare the result between population and document frequency. Secondly, in case of correlation analysis, the significant changes are revealed when the spatial criteria for search keywords are increased. In case of corpus, COM, NET, and ORG shows the higher coefficient values. Lastly, the cluster analysis is applied to classify the list of cities that shows the similarity and difference. These analyses have a significant role in representing the rank-size distribution of city names that are reflected on the web documents in the information society.

Due to the rapidly growing number of resistant strains of bacteria, the search for antibacterial agents with new modes of action will always remain an important and challenging task. Thus, the reaction of 2-substituted or. unsubstituted-4-(4-acetylanilino)-5,6,7,8-terahydrobenzo［b］ thieno［2,3-d］pyrimidine derivatives 1-3 with the hydrazine derivatives, semi and / or thiosemi-carbazides, provided the corresponding hydrazones 4-6 and semi and/or thiosemicarbazones 7-9. Claisen-Schmidt condensation of compounds 1 or 2 with the appropriate aldehyde yielded the chalcones 10, 11 which, when treated with hydroxylamine hydrochloride gave rise to the isoxazoline-containing compounds 12, 13. Furthermore, reacting the respective chalcones 10, 11 with different hydrazines, urea and/or thiourea, furnished compounds 14, 15, 16, and 17 respectively. Representative compounds were tested for their antimicrobial activity against Candida Albicans and certain gram-positive and gram-negative bacteria. Their MICs were then determined. Compound 15e, showed a broad spectrum of activity while most of the other com-pounds showed varying antimicrobial activity.

Objectives : To review the history, the theoretical basis and the technique of Intramuscular Stimulation (IMS), papers and books on IMS were searched. Methods : 15 papers were searched with the keyword 'Gunn CC' at Pubmed(http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed). Several full texts of them and other papers were found at the internet homepage of The Institute for the Study and Treatment of Pain (http://www.istop.org/). 16 Korean papers on IMS were searched at KoreaMed(http://www.koreamed.org/SearchBasic.php) and Koreanstudies Infomation Service System(http://kiss.kstudy.com/KsiKiss.asp). Results : Dr. Gunn has made unique model which can explain the pathology of chronic pain and the mechanism of acupuncture treatment. In this model, he postulated that most of chronic pain is radiculopathy due to spondylosis and acupuncture treatment to the hyperalgesic muscle can restore the normal function of involved muscles and nerves. Conclusions : IMS is an acupuncture technique in which the muscles under the Ah-shi or tender points in periphery and intrasegmental paravertebral muscles are stimulated with needles.

The internet contains enormous informations in various fields and therefore called 'sea of information'. It helps obtain quickly health related information including 'constitutional medicine'. But a lack of evaluation and oversight appear to result in inaccurate and misleading. So by using a series of equipment and www.naver.com, www.yahoo.co.kr, www.empas.com, the typical search engine for internet, the sites are researched by keyword 'constitutional medicine'. The results were classified into six groups as follows; The sites about pratitional Oriental Medical Doctor, private home page, advertisements of goods for health, associations of constitutional medicine, astrology or reading fortune, and etc. The internet is a useful tool that gives informations of health, easy and speedy, to users like as doctors and patients. But accuracy or reliabillity of this informations is mistrust. Especially informations of health are connected to safty of life directly, they must be verificated by the specialist and a criterion, that evaluate the sites it self, should be established.

As the availability of an image information has been significantly increasing, necessity of system that can manage an image information is increasing. Accordingly, we proposed the content-based image retrieval(CBIR) method based on an efficient combination of a color feature and an image's shape and position information. As a color feature, a HSI color histogram is chosen which is known to measure spatial of colors well. Shape and position information are obtained using Hu invariant moments in the luminance of HSI model. For efficient similarity computation, the extracted features(Color histogram, Hu invariant moments) are combined and then measured precision. As a experiment result using DB that was supported by http://www.freefoto.com, the proposed image search engine has 93% precision and can apply successfully image retrieval applications.

In this paper, we propose a proactive inference method of finding suspicious domains. Our method detects potential malicious domains from the seed domain information extracted from the TLD Zone files and WHOIS information. The inference process follows the three steps: searching the candidate domains, machine learning, and generating a suspicious domain pool. In the first step, we search the TLD Zone files and build a candidate domain set which has the same name server information with the seed domain. The next step clusters the candidate domains by the similarity of the WHOIS information. The final step in the inference process finds the seed domain's cluster, and make the cluster as a suspicious domain set. In experiments, we used .COM and .NET TLD Zone files, and tested 10 seed domains selected by our analysts. The experimental results show that our proposed method finds 55 suspicious domains and 52 true positives. F1 scores 0.91, and precision is 0.95 We hope our proposal will contribute to the further proactive malicious domain blacklisting research.

Objectives : The purpose of this study is to raise the proper recognition of Qigong and expand the area of Medical Qigong in the korean Medicine by investigating and analyzing the current state of Javaldonggong training which has a high medical value but there has not been little research on. Method : The survey of this study was conducted by doing a search on the internet - Naver(www.naver.com) and Daum(www.daum.net), Nate(www.nate.com), trying question-and-answer on the websites and over the phone, visiting the organizations and reading their publications. Results : None of the teachers of these selected organizations are doctors. One thing all these organizations have in common is that they are, ultimately, aiming to gain the individual enlightenment and to contribute to public welfare although the terms they use are different. As for training contents, most of these organizations use breathing, meditation, gymnastics, circuit training in addition to Javaldonggong training and they work on Javaldonggong training programs to prevent problems that Qigong training can result in. 7 organizations have published the books of the theories, which are based on their own Javaldonggong training experience. Conclusions : Applying Javaldonggong training to the therapy for the diseases is the role of a doctor of Korean medicine. A further study of and a great interest in Javaldonggong training are required for Korean medical doctors to gain a firm foothold in using it as the medical Qigong therapy.

Background : Prevalence of spasticity because of stroke are 40% patients after 12 month. Spasticity caused decrease of range of motor, motor function, and active daily living. Electroacupuncture widely used stroke. But it is been studied by systematic review between spasticity and electroacupuncture. This study is aimed to efficacy of electroacupuncture for spasticity because of stroke. Methods : We had used pubmed(www.pubmed.com) and cochrane library(www.thecochranelibrary.com) database. Limits are'human','randomized controlled trial'and'all adult 19+ years'in pubmed. The period was until 15, september, 2011. We used MeSH(Medical Subject Headings terms. The search words were'stroke'[mesh],'muscle spasticity'[mesh and 'electroacupuncture'[mesh]. In cochrane library, we used spasticity and electroacupuncture in cochrane library. We found 19 studies. But only 3 studies were included for inclusion criteria. Results : The appropriate 3 studies were different from subject, acupoint, duration of treatment, endpoint and etc. But these studies were effective for spasticity because of stroke. Conclusion : These studies were not meta analysis because of heterogeneity. But the above results might explain the electroacupuncture were effective for spasticity and further study needed to verify and standard electroacupuncture study for spasticity.
