This study aimed to investigate the current uses of subheadings that appear in medical science journal abstracts and to discuss its potential implications for medical science from the perspectives of library and information science. To conduct this study, the following nine sub-fields in medical science were selected: cancer, ethics, genetics, infectious disease, neurology, pediatrics, immunology, psychiatry, and cardiology. Random sample data were drawn based on the years 2010 to 2015 from the PubMed database. This study investigated the extent of the uses of subheadings, variants of subheadings, and common formation of subheadings with the help of a frequency analysis. The specific findings of this study are summarized as the following: 1) more traditional abstracts are used across almost all sub-fields of medical science; 2) on average, 4.1 subheadings were used in the sample dataset; and 3) the most frequently used set of subheadings is OBJECTIVES, METHODS, RESULTS, and CONCLUSIONS. This subheading set appears to be the de facto standard across all medical science journals. The analysis of subheadings in structured abstracts and the issues raised in this study can be beneficial for journal editors and other academics in medical science as well as library and information science.

This paper reviewed the following subheadings and a few selected references in each section were discussed: ${\cdot}$ Sealant placed over caries; is it possible? Initial caries which is not sticky during proving is possible to be placed with sealants. ${\cdot}$ Prophylaxis of fissure; which method is most effective? Mechanical preparation with fissurotomy or resin polishing bur is one of the most effective method to clean the pit and fissure. ${\cdot}$ Glassionomer cement as a sealant; GIC, wheather it released fluoride or not, cannot be as cost-effective as resin-based sealants. ${\cdot}$ Sealant products; Color(white vs opaque), fluoride(containing vs not), filler component(filled vs non-filled) do not influenced the quality and retention of sealants. ${\cdot}$ Use of intermediate bonding agent to improve retention; Intermediate bonding may increase the retention rate of sealants ${\cdot}$ Penetration method of sealants; Several methods including waiting before light curing are recommended.

Purpose: The aim of this study was to determine the reasons and solutions for intraoral phosphor storage plate (PSP) image artifacts and errors, and to develop an appropriate classification of the artifacts. Materials and Methods: This study involved the retrospective examination of 5,000 intraoral images that had been obtained using a phosphor plate system. Image artifacts were examined on the radiographs and classified according to possible causative factors. Results: Artifacts were observed in 1,822 of the 5,000 images. After examination of the images, the errors were divided into 6 groups based on their causes, as follows: images with operator errors, superposition of undesirable structures, ambient light errors, plate artifacts (physical deformations and contamination), scanner artifacts, and software artifacts. The groups were then re-examined and divided into 45 subheadings. Conclusion: Identification of image artifacts can help to improve the quality of the radiographic image and control the radiation dose. Knowledge of the basic physics and technology of PSP systems could aid to reduce the need for repeated radiography.

In their teaching practice, teachers encounter multi-dimensions of pedagogical challenges. The recognition and reflection on these challenges is crucial to advance our science teaching. This study looked into science teachers' dilemmas of their teaching practical work through their written cases. Dilemma cases are teachers' narratives organized around important events of teaching and learning. It can reveal teachers' situated cognition and be used as lens to investigate complex realities of science teaching and learning. 26 pre- and in-service elementary teachers' dilemma cases of science practical work were carefully collected and analysed to interpret what constitute tensions in elementary science practical works. They were largely grouped into three: Curriculum and Institutional Relevance, Students Relevance, Nature of School Experiments Relevance and divided into 7 subheadings: 'Authority of Curriculum(textbook)', 'Disappointment at external support', 'Students' interests and safety', 'Students' unscientific and inert attitude', 'Difficulty of showing expected results', 'Generalization through experiment', 'Knowledge acquisition and authentic inquiry'. Each dilemma was interpreted in terms of the tensions which constitute contradictory beliefs, values, expectation and realities. These dilemmas enabled to expose actual conditions of elementary science practical work and teachers' challenges otherwise can not be seen easily. Science teacher educators also can get some implications to overcome the gap between theory and practice in their teacher education.

Purpose: The aim of this study is to identify core keyword of frailty research in the past 35 years to understand the structure of knowledge of frailty. Methods: 10,367 frailty articles published between 1981 and April 2016 were retrieved from Web of Science. Keywords from these articles were extracted using Bibexcel and social network analysis was conducted with the occurrence network using NetMiner program. Results: The top five keywords with a high frequency of occurrence include 'disability', 'nursing home', 'sarcopenia', 'exercise', and 'dementia'. Keywords were classified by subheadings of MeSH and the majority of them were included under the healthcare and physical dimensions. The degree centralities of the keywords were arranged in the order of 'long term care' (0.55), 'gait' (0.42), 'physical activity' (0.42), 'quality of life' (0.42), and 'physical performance' (0.38). The betweenness centralities of the keywords were listed in the order of depression' (0.32), 'quality of life' (0.28), 'home care' (0.28), 'geriatric assessment' (0.28), and 'fall' (0.27). The cluster analysis shows that the frailty research field is divided into seven clusters: aging, sarcopenia, inflammation, mortality, frailty index, older people, and physical activity. Conclusion: After reviewing previous research in the 35 years, it has been found that only physical frailty and frailty related to medicine have been emphasized. Further research in psychological, cognitive, social, and environmental frailty is needed to understand frailty in a multifaceted and integrative manner.

The purpose of this study is to try finding the research possibilities of computer technology in art education and understand why computer technology has such a great impact on our contemporary education. The methodology of this study is based on the analysis of literature review. I have tried to find the importance articles in the journals of art education such as Studies in Art Education and Art Education published from the National Art Education Association, one of the most well-known organizations in the field of art education. To draw the purpose of this study, I found articles and categorized the information using key words such as aesthetic, feminist, gender issues, and interactivity. After analyzing, I have discussed about the research possibilities and important issues of computer technology in art education and then categorized the information found in each article into four different subheadings: 1) the visual effects of computer graphics in art education, 2) gender issues based on the computer technology, 3) interactive multimedia and social interactions among students, 4) research possibilities with computer technologies in art education. The findings are as follow. Firstly, there were many research possibilities of computer technologies in art education such as ways of criticizing the contemporary art world. Secondly, I found that computer technology has a great impact on art education because students are more eager to engage with computer technologies-based media activities and very familiar with new media either at home and school. Therefore, we, as educators, must address how the student will be systematically engaged with computer technologies in their educational environment and should determine what knowledge and skills prospective teachers bring to our teacher education programs and how and where they acquired this knowledge.

In order to analyze how accurately authors of Korean medical papers use MeSH terms, the key words of Korean medical papers assigned by authors (author terms) are compared with the MeSH terms listed in the corresponding MEDLINE records. A total of 1,826 author terms were used in the 415 Korean Journal of Parasitology papers published between 1989 and 1998. An average of 4.4. author terms and 9.9 MeSH terms were assigned to each paper. 35.5% of author terms matched exactly or partially with MeSH terms, the average being 1.6 terms per paper. The exact match terms consisted only 10.1%. The result of this study shows that the major difference between author terms and MeSH terms are in the use of subheadings and check tags. It indicates that the Korean authors in general do not have sufficient knowledge in selecting and using MeSH terms.

This paper presents a method and necessity of this research to study the gosijo Anthology compilation method. The cataloging work was carried out 53 species of gosijo Anthology ranging from 1910-2000's, in order to proceed with the study. There was no way to analyze the compilation of all gosijo Anthology ranging from 53 species in this article. For this reason, select the classic gosijos(模範의 古時調) of Anhwak(安廓) conducted a study gosijo Anthology compilation method. The classic gosijos(模範의 古時調) of Anhwak(安廓) are no new works, will be named as one of the subheadings of the magazine. But not less that 100 can work with and all the works reveal the artist. It also select a topic classification scheme. This point is analyzed with focus on the text to be responsible enough to think that the role of gosijo Anthology. The classic gosijos(模範의 古時調) is thought to have great significance in a few aspects. First, the gosijo The Anthology is only pyeongsijo(平時調) and can be called only sijojip which the artist recorded all the work. Second, the work presented in this gosijo Anthology are the popular songs contained in a number of Gagip(歌集) majority. Third, there is a new artist appears gosijo Anthology does not appear as a writer in the gosijosa(古時調史). They BakDaegil(朴大吉), ChoiSeobung(崔瑞鵬), OhHuisang(吳喜常), JangWooByouk(張友璧), AnSapil(安思弼), AnYungi(安胤基). Fourth, gosijo Anthology reveals the Woodae gagaek(歌客) locality and the foundation of JoSeon(朝鮮) gagok(歌曲).
