최근 XML 문서 필터링에 기반한 출판-구독(publish-subscribe) 시스템이 많은 관심을 받고 있다. 전형적인 출판-구독 시스템에서, 구독자들은 XPath 언어로 명세된 프로파일로 자신들의 관심을 표현하고, 새로운 내용들은 사용자 프로파일에 대하여 매칭 여부를 판단하여 관심을 가지고 있는 사용자들에게만 배달된다. 구독자의 수와 그들의 프로파일이 증가할수록, 시스템의 확장성이 출판-구독 시스템의 중요한 성공 요소가 된다. 이 논문에서는 FiST 시스템을 확장한 세그먼트 기반의 XML 문서 필터링 시스템인 SFiST 시스템을 제안한다. SFiST 시스템은 XML 문서 필터링에서 중복된 처리를 없애기 위해서 가지형 패턴의 사용자 프로파일에서 세그먼트를 추출하여 해시 기반의 세그먼트 테이블에 저장하고 유지한다. 이 세그먼트는 사용자 프로파일을 터스 시퀀스 형태로 표현하는데 이용되고, 효율적인 필터링을 위한 컴팩트 시퀀스 인덱스에도 사용된다. 실험을 통하여 세그먼트 기반의 SFiST 시스템이 이전의 연구인 FiST 시스템보다 좋은 성능을 가지고 있음을 보였다.

Objective: It aimed at proposing the Korean Journal of Child Studies' strategy to be promoted to international journal based on the style and format of scholarly journals and journal metrics. Methods: The review of the journal in not only print version, but also an online version was done from the perspective of style and format. The total citation and impact factor were manually calculated from Web of Science Core Collection. Results: More professional level manuscript editing is required for maintaining the consistency of the style and format. The verso page and back matters should be improved to international level. Journal homepage should be reconstructed by adopting digital standards for the journal, including journal article tag suite, CrossMark, FundRef, ORCID, and text and data mining. To become an international journal, transformation into English journal and deposition to PubMed Central is mandatory. Conclusion: Since the editor's and society members' performance is top-notch, it will be possible to promote the journal up to international level soon. Society should guarantee the term of editor for enough time and support her with full cost and complete consent.

Clinical photography is an essential component of patient care in plastic surgery. The use of unsecured smartphone cameras, digital cameras, social media, instant messaging, and commercially available cloud-based storage devices threatens patients' data safety. This paper Identifies potential risks of clinical photography and heightens awareness of safe clinical photography. Specifically, we evaluated existing risk-mitigation strategies globally, comparing them to industry standards in similar settings, and formulated a framework for developing a risk-mitigation plan for avoiding data breaches by identifying the safest methods of picture taking, transfer to storage, retrieval, and use, both within and outside the organization. Since threats evolve constantly, the framework must evolve too. Based on a literature search of both PubMed and the web (via Google) with key phrases and child terms (for PubMed), the risks and consequences of data breaches in individual processes in clinical photography are identified. Current clinical-photography practices are described. Lastly, we evaluate current risk mitigation strategies for clinical photography by examining guidelines from professional organizations, governmental agencies, and non-healthcare industries. Combining lessons learned from the steps above into a comprehensive framework that could contribute to national/international guidelines on safe clinical photography, we provide recommendations for best practice guidelines. It is imperative that best practice guidelines for the simple, safe, and secure capture, transfer, storage, and retrieval of clinical photographs be co-developed through cooperative efforts between providers, hospital administrators, clinical informaticians, IT governance structures, and national professional organizations. This would significantly safeguard patient data security and provide the privacy that patients deserve and expect.

대규모 운영시스템이나 확장성을 고려한 시스템을 구성할 때 마이크로서비스 기법을 도입하는 것이 필요하다. 카프카는 pub/sub 모델을 가지는 메시지 큐로서 분산환경에 잘 적용되는 특징을 가지며, 다양한 데이터 소스를 활용할 수 있다는 점에서 마이크로서비스에 적합하다. 이 논문에서는 아파치의 카프카를 이용한 교육동영상 공유 서비스의 데이터 공유 방안을 제안하고자 한다. 제안하는 시스템은 교육 동영상 공유서비스이 다양한 데이터를 공유하기 위해 카프카 클러스터를 구축하며, 아울러 교육동영상의 유사도를 기반으로 하는 추천 시스템과 연계하기 위해 스파크 클러스터를 이용한다. 그리고 파일, RDBMS의 DB등과 같은 다양한 데이터 소스를 공유하는 방안을 제시한다.

본 논문은 임상의사가 선호하는 임상정보원의 특성과 정보검색 시 장애요인을 심층인터뷰를 통해 분석하였다. 환자 진료를 위한 정보검색은 환자치료방법 결정, 최신 경향 파악, 내부 컨퍼런스 발표자료 준비 등으로 구분되었으며, 이러한 검색행위에 영향을 미치는 변인으로는 주제 배경지식, 진료 경험, 직급, 검색 능력, DB 이용교육, 도서관 홈페이지 친숙도 등으로 나타났다. 온라인 임상정보원은 익숙하고 신뢰성이 높고 방대한 정보의 양 때문에 PubMed가 가장 선호되었으며, 속도가 빠르고 쓰기 쉬운 구글도 많이 사용되었다. 정보내용의 정확성과 최신성이 정보원 선정에 있어 가장 중요한 기준으로 적용되었으며, 시간이 많이 부족한 관계로 검색방법의 용이성, 정보에 대한 접근 편이성도 중요하게 여겨지고 있었다. 사용하기 불편한 검색시스템, 생소한 주제나 용어의 검색 어려움, 너무나 방대한 자료, 원문 접근의 어려움, 복잡한 고급검색 기능 등이 장애요인으로 도출되었다. 본 연구결과는 도서관 서비스 개선이나 임상의사의 정보검색 교육과정을 개선하는데 기초자료로 활용될 수 있을 것이다.

Purpose: We aimed at reviewing the studies of the acupuncture treatment for women related to pregnancy. Methods: We referred to PubMed by searching words of pregnancy and acupuncture and limited experimental method to randomized control trial. Results: We found 52 articles in 32 journals, which were divided into 3 parts: treatment for symptoms during pregnancy, treatment for symptom related to delivery and treatment for symptoms related to surgical operation for IVF-ET. In this study, articles on hypermesis gravidarum were the greatest in number and acupuncture for pain control related to pregnancy are most frequently appearing in terms of symptoms. Besides acupuncture treatment, acupressure band and acupressure were used for hyperemesis gravidarum, common acupuncture for low back pain in pregnancy and acupuncture or moxibustion to resolve breech presentation. Conclusion: In this study, acupuncture seems to be an efficacious means of reducing symptoms related to pregnancy and improving the quality of life of pregnant women.

Objectives: The inherent nature of the Korean National Health and Nutrition Examination Survey (KNHANES) design requires special analysis by incorporating sample weights, stratification, and clustering not used in ordinary statistical procedures. Methods: This study investigated the proportion of research papers that have used an appropriate statistical methodology out of the research papers analyzing the KNHANES cited in the PubMed online system from 2007 to 2012. We also compared differences in mean and regression estimates between the ordinary statistical data analyses without sampling weight and design-based data analyses using the KNHANES 2008 to 2010. Results: Of the 247 research articles cited in PubMed, only 19.8% of all articles used survey design analysis, compared with 80.2% of articles that used ordinary statistical analysis, treating KNHANES data as if it were collected using a simple random sampling method. Means and standard errors differed between the ordinary statistical data analyses and design-based analyses, and the standard errors in the design-based analyses tended to be larger than those in the ordinary statistical data analyses. Conclusions: Ignoring complex survey design can result in biased estimates and overstated significance levels. Sample weights, stratification, and clustering of the design must be incorporated into analyses to ensure the development of appropriate estimates and standard errors of these estimates.
