  • Objective: To evaluate the diagnostic accuracy of contrast-enhanced ultrasonography (CEUS) in differentiating between benign and malignant enlarged lymph nodes using meta-analysis. Materials and Methods: Pubmed, Embase, SCI and Cochrane databases were searched for studies (up to September 1, 2014) reporting the diagnostic performance of CEUS in discriminating between benign and malignant lymph nodes. Inclusion criteria were: prospective study; histopathology as the reference standard; and sufficient data to construct $2{\times}2$ contingency tables. Methodological quality was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Patient clinical characteristics, sensitivity and specificity were extracted. The summary receiver operating characteristic curve was used to examine the accuracy of CEUS. A meta-analysis was performed to evaluate the clinical utility in identification of benign and malignant lymph nodes. Sensitivity analysis was performed after omitting outliers identified in a bivariate boxplot and publication bias was assessed with Egger testing. Results: The pooled sensitivity, specificity and AUROC were 0.92 (95%CI, 0.85-0.96), 0.91 (95%CI, 0.82-0.95) and 0.97 (95%CI, 0.95-0.98), respectively. After omitting 3 outlier studies, heterogeneity decreased. Sensitivity analysis demonstrated no disproportionate influences of individual studies. Publication bias was not significant. Conclusions: CEUS is a promising diagnostic modality in differentiating between benign and malignant lymph nodes and can potentially reduce unnecessary fine-needle aspiration biopsies of benign nodes.

  • The purposes of the study is to see as to how much of changes has occurred in the newly revised Home Economics Textbooks required by the 6th Curriculum as compared to those by the former the 5th Curriculum, and to seek future policy directions which can be improved even better, if any, for further revision. To implement this proposal, the study employs 8 different textbooks published in 1997 geared for the 6th Curriculum for data base. The components of the contents divides into two major parts. The first part falls into a category of holistic analysis of the textbooks, which gives a general perspective of the changes in the textbook revised. It includes those areas of changes in the total number of pages, cover page, illustrations, table of contents, appendices, unit cover, introductory remarks, summary and evaluation, etc. It also covers the information on authors of textbook. The latter part consists of several specific areas of major changes occurred in the textbooks for the 6th Curriculum. It covers such areas of changes in the composition of category and its weight, laboratory experiences, and illustrations and tables. To conclude the study, among many findings, two major points are of great importance to mention here. First, the new textbooks have adopted more of varieties in physical appearances and contents per se as to the older ones. And yet, there still found a weakness in numbers of authors participated to a full reflection of contents variety. In addition, the background of authors reflected on an unrealistic idealism which lacks the on-site information provided by the school teachers. Second, the strict regulations created by the Ministry of Education for developing textbook found restricting the authors creativity and thus contents variety of textbooks. Those restricting factors include letter type and size, coloring, paper quality, and volume size.

  • University libraries aim to improve not only educational effects but also the general quality of colleges. A primary way of pursuing this goal is through providing professors and students with sufficient amounts of available references and materials that can be used for academic purposes. However, even though university libraries are intended to be used by college students majoring in different fields, they tend to provide mostly books. This limited offering of resources means that they are not distinguishing themselves from regular libraries. The purpose of this study is to present basic data for the spatial design of a subject specialization room in a college library. Included in the design are recommendations for the type and placement of the furniture in the room. The summary of results for this study and the conclusions are as follows: The layout of data space and reading space in a subject specialization room can be categorized into both document-oriented (document centralized and document categorized) and reading-oriented (reading centralized, all, and group types). The public reading seats and private reading seats in a subject specialization room, according to their ratio, can be divided into private reading, public reading, and distributed reading sections. The ratio of open-spaced tables is higher for groups of four or more people, but users often sit separately from others in order to ensure privacy. Unfortunately, this practice results in seating gaps that do not make efficient use of space. The result is that the public reading seats are less efficient than the private reading seats in terms of space. Therefore, it is necessary to increase the number of cubicles.

  • Background: Traditional plant drugs, are less toxic and free from side effects compared to general synthetic drugs. They have been used for the treatment of diabetes and associated renal damage. In this study, we evaluated effect of Hachimi-jio-gan against diabetic renal damage in a rat model of type 1 diabetic nephropathy induced by subtotal nephrectomy plus streptozotocin (STZ) injection, and in Otsuka Long-Evans Tokushima Fatty (OLETF) rats and db/db mice as a model of human type 2 diabetes, and its associated complications. To explore the active components of Hachimi-jio-gan, the antidiabetic effect of corni fructus, a consituent of Hachimi-jio-gan, and 7-O-galloyl-${{\small}D}$-sedoheptulose, a phenolic compound isolated from corni fructus, were investigated. Methods and Results: We conducted an extensive literature search, and all required data were collected and systematically organized. The findings were reviewed and categorized based on relevance to the topic. A summary of all the therapeutic effects were reported as figures and tables. Conclusions: Hachimi-jio-gan serves as a potential therapeutic agent to against the development of type 1 and type 2 diabetic nephropathy. From the results of characterization active components of corni fructus, 7-O-galloyl-${\small}D$-sedoheptulose is considered to play an important role in preventing and/or delaying the onset of diabetic renal damage. 7-O-Galloyl-${\small}D$-sedoheptulose is expected to serve as a novel therapeutic agent against the development of diabetic nephropathy.

  • 본 연구의 목적은 2015 개정 교육과정이 반영된 기술·가정(의생활 영역) 교과서 12종을 비교하여 새로운 교육내용에 대한 정보를 제공하는데 있다. 구체적으로 의생활 영역의 단원 세부 구성 체제 및 학습목표, 분량, 삽화, 진로 교육 내용 등을 분석하였다. 또한 현재 교과서의 내용 측면의 장점은 무엇인지 파악해보고, 앞으로의 개선방향도 제시해 보고자 하였다. 연구 결과 교과서 집필진 수가 가장 많은 교과서는 19명, 가장 적은 교과서는 9명으로 10명의 차이가 났다. 단원 구성은 12종의 교과서 모두 대단원은 2개로, 중단원은 2개 또는 4개로 유사하였으나, 소단원은 교과서별로 단원명과 개수가 가장 상이하게 나타났다. 단원의 세부 구성은 도입, 전개, 정리 체제로 용어는 다르지만 비슷한 흐름으로 제시 되었고, 교과서마다 특색 있는 자료 및 활동을 제시하였다. 분량 분석은 가장 많은 교과서가 38쪽, 가장 적은 교과서가 24쪽으로 차이가 있었다. 교과서의 삽화는 그림이 가장 많이 수록되어 있었고, 사진, 표, 그래프 순이었다. 삽화가 가장 많이 제시된 교과서는 총 69개이고, 가장 적게 제시된 교과서는 38개로 큰 차이를 보였다. 마지막으로 진로교육의 반영에서는 12개의 교과서 중에서 8개의 교과서가 진로 관련 내용을 반영하고 있었다. 교과서마다 집필진 수, 분량, 삽화의 사용수는 달랐으나 내용적인 측면에서는 대부분 2009 개정 교과 내용은 대부분 그대로 다루면서 의복의 의미, 구매 계획, 옷차림, 창의적 의생활이라는 주제를 추가시켜 교육목표를 넓은 범위로 확대시키며 구체적인 학습목표도 제시하였다. 결론적으로 2015 개정은 미래사회를 이끌어갈 인재 육성이 가능하도록 구체적인 지침을 제시하고, 자기주도적 학습이 가능하도록 하는 것이 장점이었다.

  • 마닐라만은 3개의 항구가 있는 마닐라항의 집과 같다: 북항, 남항 그리고 MITC. 북항 부근과 마닐라만을 가로질러 리마오라는 어항이 있다. 이 연구는 마닐라만에서 마닐라 VTMS 원 데이터의 입출항 교통량만을 기준으로 교통량의 움직임에 집중한다. 이는 2010, 2011년 2년 동안의 교통량이다. 데이터의 표시를 교통량의 숫자로; G. T.에 의한 크기로; 낮이든 밤이든 선박 동향의 시간으로; 각 국내와 국외 각 항차 거래로 나뉜다. 양적인 수치는 모든 개체군을 기반으로 한 원 데이터로부터 계산된다. 그 결과의 수치는 통계상의 측정된 표와 그래프에 의해 나타난다. 산술평균은 개체군의 변동계수와 표준편차가 요약된 형태로 보여지는 것을 의미한다. 그렇기 때문에, 그것들은 교통량의 빈도와 양의 더 나은 그림을 보여주기 위해 해석된다. 끝으로 본 연구가 필리핀의 가장 중요한 항구의 안전성 향상에 기여하기를 기대한다.
