  • Now a days, number of non alcoholic fatty liver patients are increasing more rapidly compare to past rate, and the average age of patients is getting younger, but there are no appropriate therapeutics in non alcoholic fatty liver disease. This study was aimed to analyze relationship between non alcoholic fatty liver disease and Injinho-tang. The papers were collected and analysed from domestic and international journals. The effects of Injinho-tang and constituent-herb were researched. Non-alcoholic fatty liver disease was induced complex causes of the metabolic syndrome. Medications that can be used in non-alcoholic fatty liver disease, it should be have many effects such as anti-hepatic fibrosis, hepatocyte protection, liver cancer inhibitory effect, inflammatory cytokine regulation, improving hyperlipidemia, weight control, decrease the toxicity of the drug, antioxidant. Injinho-tang (Artemisia capillaris Thunb, Gardenia fructus, Rhei rhizome) has been widely used in disease that causes jaundice and liver biliary disease. Drugs for standardization of Injinho-tang index components(6,7-Dimethylesculetin, geniposide, rhein) have been presented. And Injinho-tang has been proven reliability in the administration of single dose toxicity. Also clinical stability in the administration of four years was reported. Injinho-tang has been reported some effects which anti-hepatic fibrosis, hepatocyte protection, liver cancer inhibitor, inflammatory cytokine regulation, improving hyperlipidemia, weight control, decrease the toxicity of the drug, and antioxidant. Therefore, Injinho-tang can be used in Non alcoholic fatty liver disease without Syndrome Differentiation.

  • 본 논문에서 언급하는 세계지리는 한국지리를 배제한 세계지리만을 의미한다. 본 논문은 지난 21년 동안 한국 지리학계의 세 학회지 ("대한지리학회지", "한국지역지리학회지", "문화역사지리")에 게재된 세계 지리논문을 조사 분석하여 한국지리학계의 세계지리 연구 동향을 고찰하는 연구이다. 세계지리 논문의 비율이 가장 높은 시기는 1995-1999년 동안이고, 가장 낮은 시기는 1990-1994년 동안이다. 2000-2004년과 2005-2010년 동안에는, 1990년대 후반에 비하여, 세계지리 논문의 비율이 오히려 감소하고 있는 것으로 나타난다. 한국 지리학계에는 세계지리 논문의 비율이 너무 낮을 뿐만 아니라 세계지리 논문의 연구지역이 주로 미국, 일본, 중국, 유럽에 한정되어 있다는 한계가 있다. 세계화 국제화 사회에 그리고 다문화사회에 접어든 한국의 현실을 감안할 때, 한국 지리학계의 세계지리 연구 활성화를 기대해 본다.

  • Background : The publication rate of presentations at medical international meetings has ranged from 11% to 78% with an average of 45%. To date, there are no studies about the final rate of publications at scientific meetings associated with plastic surgery from Korea. The present authors investigated the publication rate among the presentations at meetings associated with plastic surgery. Methods : The titles and authors of the abstracts from oral and poster presentations were collected from the program books of the Congress of the Korean Society of Plastic and Reconstructive Surgeons (CKSPRS) for 2005 to 2007 (58th-63rd). All of the abstracts presented were searched for using PubMed, KoreaMed, KMbase, and Google Scholar. The titles, key words from the titles, and the authors' names were then entered in database programs. The parameters reviewed included the publication rate, type of presentation including running time, affiliation, subspecialty, time to publication, and publication journal. Results : A total of 1,176 abstracts presented at the CKSPRS from 2005 to 2007 were evaluated. 38.7% of the abstracts, of which oral presentations accounted for 41.0% and poster presentations 34.8%, were published as full papers. The mean time to publication was 15.04 months. Among journals of publication, the Journal of the Korean Society of Plastic and Reconstructive Surgeons was most used. Conclusions : Brilliant ideas and innovative approaches are being discussed at CKSPRS. The 38.7% publication rate found from this research appeared a bit lower than the average rate of medical meetings. If these valuable presentations are not available as full papers, the research would be a waste of time and effort.

  • 현재 4차 산업혁명을 맞이하여 머신러닝과 인공지능 기술이 급속도로 발전하고 있으며 보안 분야에서도 머신러닝 기술을 응용하려는 움직임이 있다. 많은 악성코드가 생성됨에 따라 사람의 힘으로는 모든 악성코드를 탐지하기 어려워지고 있기 때문이다. 이에 따라 학계와 산업계에서는 머신러닝을 통해 악성코드나 네트워크 침입 이벤트를 탐지하는 것에 관한 연구가 활발히 진행되고 있으며 국제 학회와 저널에서는 머신러닝의 한 분야인 딥러닝을 이용한 보안데이터 분석 연구가 논문 발표되고 있다. 그러나 해당 논문들은 검출 정확도에 초점이 맞추어져 있고 검출 정확도를 높이기 위해 여러 파라미터들을 수정하지만 Dataset의 개수를 고려하지 않고 있다. 따라서 본 논문에서는 CNN Mobile net 기반 악성코드 탐지 모델에서 가장 높은 검출 정확도를 도출할 수 있는 Dataset의 개수을 찾아내어 많은 머신러닝 연구 진행에 비용과 리소스를 줄이고자 한다.

  • Objective: The efficacy of mandibular advancement devices (MADs) in the treatment of obstructive sleep apnea (OSA) ranges between 42% and 65%. However, it is still unclear which predictive factors can be used to select suitable patients for MAD treatment. This study aimed to systematically review the literature on the predictive value of cephalometric analysis for MAD treatment outcomes in adult OSA patients. Methods: The MEDLINE, Google Scholar, Scopus, and Cochrane Library databases were searched through December 2014. Reference lists from the retrieved publications were also examined. English language studies published in international peer-reviewed journals concerning the predictive value of cephalometric analysis for MAD treatment outcome were considered for inclusion. Two review authors independently assessed eligibility, extracted data, and ascertained the quality of the studies. Results: Fifteen eligible studies were identified. Most of the skeletal, dental, and soft tissue cephalometric measurements examined were widely recognized as not prognostic for MAD treatment outcome; however, controversial and limited data were found on the predictive role of certain cephalometric measurements including cranial base angle, mandibular plane angle, hyoid to mandibular plane distance, posterior nasal spine to soft-palate tip distance, anterior nasal spine to epiglottis base distance, and tongue/oral cross sectional area ratio thus justifying additional studies on these parameters. Conclusions: Currently available evidence is inadequate for identification of cephalometric parameters capable of reliably discriminating between poor and good responders to MAD treatment. To guide further research, methodological weaknesses of the currently available studies were highlighted and possible reasons for their discordant results were analyzed.

  • The Trust and Authority in Scholarly Communications in the Light of the Digital Transition research project1) was a study which investigated the behaviours and attitudes of academic researchers as producers and consumers of scholarly information resources in respect to how they determine authority and trustworthiness. The research questions for the study arose out of CIBER's studies of the virtual scholar. This paper focuses on elements of this study, mainly an analysis of a scholarly publisher's usage logs, which was undertaken at the start of the project in order to build an evidence base, which would help calibrate the main methodological tools used by the project: interviews and questionnaire. The specific purpose of the log study was to identify and assess the digital usage behaviours that potentially raise trustworthiness and authority questions. Results from the self-report part of the study were additionally used to explain the logs. The main findings were that: 1) logs provide a good indicator of use and information seeking behaviour, albeit in respect to just a part of the information seeking journey; 2) the 'lite' form of information seeking behaviour observed in the logs is a sign of users trying to make their mind up in the face of a tsunami of information as to what is relevant and to be trusted; 3) Google and Google Scholar are the discovery platforms of choice for academic researchers, which partly points to the fact that they are influenced in what they use and read by ease of access; 4) usage is not a suitable proxy for quality. The paper also provides contextual data from CIBER's previous studies.

  • Objectives : The purpose of this study is to explore the trends of Chuna(manipulation) treatment on neck pain and cervical disc displacement. Methods : We set up the two searching strategies and investigated the latest clinical trials on Chuna(manipulation) therapy for Neck disorders and cervical disc herniation through PubMed search. The searched papers were analyzed and the year, journals, article types of literatures were examined. Of the articles, Randomized controlled trials(RCTs) are assessed by Jadad scale. Results : Studies on Chuna(manipulation) treatment to cervical disc herniation were very few. Articles on Chuna(manipulation) treatment to neck pain were relatively more than those of cervical disc herniation. The most frequently published journal was J Manipulative Physiol Ther. The main design of study was RCT. The limited quality assessment of RCT was conducted by Jadad scale and the average Jadad score was 1.73, which indicates low quality in terms of Jadad evaluation criteria. Conclusions : International trends of studies on Chuna therapy of cervical disease is increasingly reviewed. Although this review has several limitations, analyzing the latest trends of studies on Chuna(manipulation) treatment on neck pain and cervical disc displacement is necessary for further studies.

  • Are the benefits derived from ICT based reference and information service worth the financial and other commitments devoted to it? In an attempt to answer this, this study delved into finding out the perceived benefits; the rational for ICT based reference services in Nigerian university libraries. The main objectives were to find out the purposes for using ICT facilities in reference services delivery and the perceived benefits derived from using ICT resources in reference and information services. Being a survey, questionnaire was used to collect data from the librarians of twelve (12) universities; two (2) each sampled from the six geopolitical zones of Nigeria. Data was analyzed using frequencies, mean scores and standard deviations. ANOVA statistical analysis was used to test the hypothesis of no significance difference in the benefits derived from ICT based reference services using p-value of 0.05 to calculate the level of significance. Findings showed that librarians and library users made use of ICT facilities for different reference purposes especially to obtain information they need using the internet. Other reference needs for which patrons used the ICT facilities included: - access to current e-books and e - journals, user education and access to global information in other libraries. Provision of current awareness services (CAS) and selective dissemination of information services (SDI), on-line searching using workstations in the library, provision of on-line public access catalogue (OPAC) services, keeping statistics of users of the reference section and compilation of bibliographies. Further findings showed that the librarians and library users derive a lot of benefits from their use of ICT facilities in reference services. The results showed that easy retrieval and dissemination of information to patrons were ranked highest by the librarians amongst others.
