The purpose of this study is to investigate the blood pressure reducing effect of Qi-Ju-Di-Huang-Wan (QJDHW) in adults with essential hypertension by using methods of systemic review and meta-analysis. Major search engines, such as PubMed, EMBASE, Cochrane library, Web of Science, CNKI, CiNii, J-STAGE, KISS, NDSL, RISS, OASIS, DBpia and so on, were used. The search period we used is from the start date of the search engine to October 30, 2016 and no language limits were placed. Randomized controlled trials using QJDHW in adults with essential hypertension were searched and extracted by two independent researchers. Meta-analysis was performed on outcome variables of the total effective rate (TER), systolic blood pressure (SBP) and diastolic blood pressure (DBP). Risk of bias (RoB) of Cochrane was used to assess methodological quality. Thirteen studies were finally selected. We observed that the combined treatment of QJDHW and antihypertensive drug had 3.6 times the odds ratio of TER for blood pressure lowering than a single use of an antihypertensive drug. Additionally, mean differences of SBP and DBP were -8.88 mmHg (95% Confidential Interval (CI) -12.77 mmHg, -5.00 mmHg, P<0.00001), -7.09 mmHg (95% CI -9.93, -4.25, P <0.00001), respectively. Single use of QJDHW did not reduce blood pressure more than an antihypertensive drug. All items of RoB were unclear and the methodological quality was low. Our analysis suggests that the combination of QJDHW and antihypertensive drugs may be more effective in reducing blood pressure than a single antihypertensive drug. But due to low methodological quality, careful interpretation will be needed and systematic long-term clinical trials will be required.

Objective : This study aimed to review the performance of traditional herbal prescriptions for treating dementia and present a strategy for research on dementia therapy utilizing herbal medicine. Methods : A definition was made to clarify the technology regarding the development of herbal prescriptions for treating dementia. The queries were compounded based on the initial keywords provided by experts in the field, then applied to the Web of Science database search engines from January 1986 to September 2011 to search related scientific articles. Before performing the analysis, papers were extracted from the initial search reviewed by experts and 80 articles were selected. Then, the selected papers were analyzed in terms of publish year, country, and type of herbal prescriptions. Furthermore, the research performance evaluation for treating dementia by herbal prescriptions was also created in terms of country and organization based on forward citation analysis. In addition to, for the evaluation regarding research quality, we classified and reviewed papers into two types: clinical studies and experimental studies. Results : According to the quantitative information analysis of 80 articles, the number of papers has increased by 21.9% per the yearly mean from 1995, and Japan had the largest portion within this research field. There were 34 kinds of traditional herbal prescriptions, among them Ukgansan had the highest number of studies followed by Jodeungsan, Dangkisoosan and so on. In addition, quality index as calculated by cites per paper is higher than average in Switzerland, Turkey and Japan. In the view of the evaluation on quality there were 12 clinical studies, 8 RCT reported that herbal prescriptions had efficacy at cognition, behavioral & psychological symptoms (BPSD) and activity of daily life (ADL) in various type of dementia. In experimental studies most of the studies were performed using animal models. The studies using Ukgansan were aimed at improving BPSD. The papers studied with Jodeungsan and Dangkisoosan targeted vascular dementia. Conclusions : In this study, research to develop traditional herbal prescriptions for treating dementia has the potential to improve symptoms since herbal medicines work as both multi-function and multi-target in dementia with multiple pathological or neurotoxic pathways. Therefore, the results of the research should be used in order to establish strategies to develop technology for treating dementia with traditional herbal prescriptions in the future.

Objectives : This study reviews the latest articles in Korea and other countries that studied oriental medicine treatment on poststroke depression. Methods : Korean articles were retrieved from the 9 major Korean web article search engines. Foreign articles were retrieved from PubMed. Article published date was from 2000 up to September 2012. There were no restrictions on the types of publication, but articles not available in full text were excluded. The methodological quality was assessed according to Cochrane's assessment of risk of bias and Newcastle-Ottawa quality assessment scale. Results : Twenty-two articles were included in this study. Eleven articles were published in Korea, the rest were published in China. Nine articles were randomized controlled trials (RCT), one article was a non-randomized study (NRS), four articles were case reports, three articles were cross-sectional studies, two articles were comparative studies. In RCT articles, risk of selection bias and performance bias were generally high, risk of detection bias was unclear. The NRS article took four stars in Newcastle-Ottawa quality assessment. Comparison Hamilton rating scale for depression score between oriental medicine treated group and western medicine treated group revealed that there was no remarkable difference in mean score changes after treatment on PSD. Conclusions : The results of this study suggest that oriental medicine treatment is as effective as western medicine treatment for PSD. In the future, more rigorous oriental medicine treatment studies should be conducted.

Objectives : Despite the substantial amount of newspaper coverage related to complementary and alternative medicine on the internet in recent years, little is know about the quality of the health information. To evaluate health information of the newspaper articles on moxibustion available in Korea through Korean language search engines and Web sites. Methods : We searched 454 news stories about moxibustion between 1 January 2006 and 31 December 2008. Among them, 34 internet news coverage related to health information on moxibustion were selected and rated against eight categories by two individuals. Results : The inter-rater reliability of the two reviewers was assessed as 0.69, indicating a moderately high level of agreement. The overall rating score for 34 articles was 35.7${\pm}$17.2 for the statement criteria and 12.9${\pm}$17.0 for the satisfaction criteria. Overall, although they might be improving recently, the scores remain generally low. There was a statistically significant difference in the score of the newspaper coverage according to the type of evidence sources, including anecdotes. Conclusions : There is substantial variability in news reporting practices about moxibustion. It is urgently needed to enhance the information related to CAM including moxibustion through the news media in Korea.

This study carried out to assess the quality of the information presented on the internet about nutrition specifically in the field of health functional food by monitoring with 10 panels from May, 2004 to October. Four hundred seven relevant websites were initially selected from a process using 5 search engines and the keywords ‘food’ and ‘nutrition’, and 404 sites actually met all inclusion criteria. Most of the sites evaluated 219 (54.20%) were commercial sites and then distributed noncommercial organization site 93 (23.0%), individual site 92(22.8%). Assessment quality indicator was carried out using the 17 necessary requisites, which has been developed to enable users and information providers to judge the quality of food and nutrition information. The mean score for quality grade was 11.07, five site out of a maximum score of 17 and two sites with the lowest total scores for the quality of food and nutrition information. Noncommercial organization site assessed achieved the highest score in accurate and useful informations to the public. Low ranked sites had the most inaccurate or misleading information, emphasizing only the positive aspects of the information, with little or no evidence. Many commercial sites used personal testimony as the most popular ‘proof’ for the effectiveness of product. This was anecdotal rather than scientific evidence based on which the objective validation was difficult to be made. Therefore, it can be challenging for both public and health professionals, to sort out useful information from a plethora of advertisements and promotions on the web sites. Our results suggest that nutrition professionals should talk about useful information of health, food and nutrition with public and help them find the best available information when using the internet.

P2P는 현재 활발히 진행되고 있는 비즈니스의 중요한 변화를 표현하는 함축적 용어라는 의미를 가진다. P2P 서비스는 인터넷상의 정보를 검색엔진을 거쳐 찾아야 하는 기존 방식과 달리 인터넷에 연결된 모든 개인 컴퓨터로부터 직접 정보를 제공받고 검색은 물론 내려 받기까지 할 수 있는 서비스이다. 이는 웹 사이트에 한정돼 있던 정보추출 경로를 개인이나 회사가 운영하는 데이터베이스로까지 확대할 수 있다. 즉 자신의 정보를 전국적 혹은 세계적으로 관리 운용하며, 회원 상호간의 다양한 정보 공유뿐만 아니라 동일한 정보를 공유하고자 하는 회원간의 커뮤니티 형성이 가능하며, 그룹웨어로서 역할을 통해 원격회의, 원격교육 등이 가능하다는 것이다.

인터넷을 통해서 수집할 수 있는 정보가 방대해지고 검색엔진이 고도화되면서 웹을 사용해서 정보를 수집하는 것이 일반화되었다. 전자책 등 디지털 자료는 인터넷이 가능한 곳에서는 어디서든지 이용할 수 있으며 디지털 정보에 대한 수요는 더욱 더 늘어날 것이다. 본 연구에서는 디지털 자료의 중요성과 비중이 커짐에 따라 전통적인 종이 자료와 디지털 자료의 모두를 한 공간에서 다루는 새로운 도서관의 모델을 제안하기 위해 문헌조사, 큐슈대학 부속도서관의 각종 통계자료 분석, 도면 및 현장조사 등을 분석하였다. 연구결과 도서관은 자료의 제공 이외에도 학습의 장소, 커뮤니티를 위한 사람들의 교류의 장소 등 사회 문화적 역할도 중요하며, 또한 디지털 자료의 비중이 커지면서 도서관 "공간"의 역할에 대하여 근본적으로 재검토할 필요가 있었다. 도서관의 공간을 매체의 형태와는 관계없이 주제 중심으로 하나의 공간에 재구성하는 하이브리드도서관에서는 이용자가 동일한 지역에 체류하면서 도서관자료나 인적서비스 등 원스톱 서비스를 제공 받을 수 있다.
