  • Staphylococcus aureus is a well-recognized human pathogen that causes a wide range of infections as a result of its extensive virulence factors. One of these factors is Panton-Valentine leukocidin (PVL), a potent pore-forming cytotoxin that has been linked to invasive S. aureus infections. PVL is one of the important virulence factors for S. aureus and has been largely recognized as one of the markers for community-acquired methicillin-resistant S. aureus. However, the presence of PVL in methicillin-susceptible S. aureus infections is not widely reported in the literature. Thrombotic sequelae of S. aureus infections associated with PVL expression are uncommon in children. We hereby report two children with thrombotic complications associated with PVL-producing methicillin-susceptible S. aureus. Both patients responded well to antibiotic and anticoagulant therapies, and survived without any long-term sequelae.

  • 타이젠(Tizen)은 Linux 오픈 소스와 그리고 웹기반의 모바일 운영체제이다. 삼성전자와 인텔, 리눅스 재단(Linux Foundation)이 주도하고 여러 협회사들이 참가하여 개발이 진행 되었다. Tizen은 태블릿컴퓨터, 넷북, 스마트폰, 스마트 TV, 차량용 인포테인먼트 시스템(In-Vehicle Infortainment)등에 사용할 수 있도록 설계 되었다. Tizen 이 Linux 와 오픈 소스에 기반을 두고 있다는 점은 안드로이드(Android)와 유사하다. 하지만 Tizen 의 응용프로그램 개발을 위한 소프트웨어 프레임워크는 주로 W3C(World Wide Web Consortium)의 웹표준과 WAC(Wholesale Application Community)의 웹기술에 기반을 두고 있으며 그 밖에도 Tizen 고유의 기술도 사용하고 있다. 본 논문에서는 Tizen 의 응용프로그램인 Tizen 웹어플리케이션의 특징과 구성에 대해서 살펴 본다. 마지막으로 안드로이드 응용프로그램과 비교하여 장단점을 조명해 본다.

  • With the rapid increase of information on the World Wide Web, finding useful information on the internet has become a major problem. The recommendation system helps users make decisions in complex data areas where the amount of data available is large. There are many methods that have been proposed in the recommender system. Collaborative filtering is a popular method widely used in the recommendation system. However, collaborative filtering methods still have some problems, namely cold-start problem. In this paper, we propose a movie recommendation system by using social network analysis and collaborative filtering to solve this problem associated with collaborative filtering methods. We applied personal propensity of users such as age, gender, and occupation to make relationship matrix between users, and the relationship matrix is applied to cluster user by using community detection based on edge betweenness centrality. Then the recommended system will suggest movies which were previously interested by users in the group to new users. We show shown that the proposed method is a very efficient method using mean absolute error.

  • Hypertension is the major factor of most death and high blood pressure (BP) can lead to stroke, myocardial infarction and cardiac failure. Moreover, hypertension is strongly correlated with body mass index (BMI). Although the exact causes of hypertension are still unclear, some of genetic loci were discovered from genome-wide association study (GWAS). Therefore, it is essential to study genetic variation for finding more genetic factor affecting hypertension. The purpose of our study is to conduct a CNV association study for hypertension-related traits, BP and BMI, in Korean individuals. We identified 2,206 CNV regions from 3,274 community-based Korean participants using the Affymetrix Genome-Wide Human SNP Array 6.0 platform and performed a logistic regression analysis of CNVs with two hypertension-related traits, BP and BMI. Moreover, the 4,692 participants in an independent cohort were selected for respective replication analyses. GWAS of CNV identified two loci encompassing previously known hypertension-related genes: LPA (lipoprotein) on 6q26, and JAK2 (Janus kinase 2) on 9p24, with suggestive p-values (0.0334 for LPA and 0.0305 for JAK2 ). These two positive findings, however, were not evaluated in the replication stage. Our result confirmed the conclusion of CNV study from the WTCCC suggesting weak association with common diseases. This is the first study of CNV association study with BP and BMI in Korean population and it provides a state of CNV association study with common human diseases using SNP array.

  • Our medical care system is trying to diversify in order to meet the client's needs, and to adjust to a medical environment which is changing very rapidly. Because current nursing theory and practice focus on holistic care, health care management, education, and research, contrary to the traditional emphasis on only assisting a physician, more autonomy and specialization for the implementation of nursing are required. Considering these trends and actual needs, the category of clinical nurse specialist should be established as soon as possible. In order to develop strategies for implementing this new professional specialty, the authors conducted a field survey and literature review of the current system in Korea. As a result, various obstacles and constraints were discovered as follows : 1) There are few accredited educational programs for the training of CNS's. 2) Several hospitals already have staff designated as clinical nurse specialist (CNS) even though the term CNS is not yet standardized or adopted in nationwide. 3) The role of the CNS is not clearly understood by the medical societies, or even nursing societies. A nurse who works in specific nursing areas such as central supply, kidney dialysis, intensive care, coronary care, etc. for a long time, considers herself /himself a CNS. Based upon the above findings, the following alternatives are recommended. 1) The role of the CNS should be defined according to specified functions and authority : professional autonomy ; counselling and educating patients and their familes, nurses, and even other medical personnel ; research on improvement of nursing ; and management of the nursing environment including medical resources, information, and cases. 2) the qualification of CNS should be attained only by a nurse who has an RN license and clinical experience of more than 3 years in a specific nursing field: passes a qualifying examination; and contributes to the professional development of peers, colleagues, and others. A master's degree should only be optional, because of the insufficient of graduate programs which are well designed for the CNS. 3) The CNS should initially be a head nurse rather than line staff in order to deal with as wide an experience base as possible. 4) The nursing specialty could be divided into two areas such as a clinical field and a community field. The clinical field could then be categorized by the Styles' classification such as diseases and pathogenics, systems, ages, acuity, skills/techniques, and function/role ; the community field could be classified according to work site.

  • Background: Punjab state is particularly reporting a rising burden of cancer. A 'door to door cancer awareness and early detection campaign' was therefore launched in the Punjab covering about 2.67 million population, wherein after initial training accredited social health activists (ASHAs) and other health staff conducted a survey for early detection of cancer cases based on a twelve point clinical algorithm. Objective: To ascertain unit cost for undertaking a population-based cancer awareness and early detection campaign. Materials and Methods: Data were collected using bottom-up costing methods. Full economic costs of implementing the campaign from the health system perspective were calculated. Options to meet the likely demand for project activities were further evaluated to examine their worth from the point of view of long-term sustainability. Results: The campaign covered 97% of the state population. A total of 24,659 cases were suspected to have cancer and were referred to health facilities. At the state level, incidence and prevalence of cancer were found to be 90 and 216 per 100,000, respectively. Full economic cost of implementing the campaign in pilot district was USD 117,524. However, the financial cost was approximately USD 6,301. Start-up phase of campaign was more resource intensive (63% of total) than the implementation phase. The economic cost per person contacted and suspected by clinical algorithm was found to be USD 0.20 and USD 40 respectively. Cost per confirmed case under the campaign was 7,043 USD. Conclusions: The campaign was able to screen a reasonably large population. High to high economic cost points towards the fact that the opportunity cost of campaign put a significant burden on health system and other programs. However, generating awareness and early detection strategy adopted in this campaign seems promising in light of fact that organized screening is not in place in India and in many developing countries.

  • In order to understand the environmental factors affecting the waterbird community in winter, we divided the watershed into 6 sections and investigated the size of the stream, the water quality, benthic invertebrates, and fish including birds. The influences on the community of water birds in Wonju stream were river structure, temperature and water quality. Among the structure of the river, the factors affecting the waterbird community in winter were the width of the stream and the width of the flowing water. The wider the width, the more species and the number of the winter waterbirds were. As the width of river water was wide, the smaller the width and width of the waterway, the fewer the population. The temperature changes of the wintering season affected the community of water birds because it led to freezing of rivers. The sections that were not frozen showed a significant increase and decrease in the temperature drop and rise. The values of pH, water temperature, COD, BOD, TN, TP and total E. coli increased with the increase of the downstream waterbirds population in the water quality survey. The water quality of S6 was affected by the downstream sewage treatment plant The number of wintering waterbirds was also highest. The effluent from the sewage treatment plant seems to have a considerable influence on the water quality. The increase of several items such as TN promotes the nutrition of the river, which leads to the accumulation of organic matter and the proliferation of aquatic organisms. This may be the cause of the increase in winter waterbirds as a food source. The benthic macroinvertebrate communities and fish communities did not show any correlation with the wintering water-birds communities.
