Objectives Postpartum blues is known to be a major risk factor for postpartum depression and can be associated with the problems of language skills, behaviors or learning skills of their children. Therefore, it is very important for clinicians to evaluate precisely and control postpartum blues. Recent studies have found that music has an effect on depressive mood and the frontal EEG asymmetry of the patients with depression. The purpose of this study was to find out the effects of music on the frontal EEG asymmetry of the mothers with postpartum blues. Method Among one hundred and seventy mothers assessed with Korean version of the Edinburg Postnatal Depression Scale (EPDS), nine mothers with postpartum blues (EPDS ${\geq}$ 10) as postpartum blues group and nine non-depressive mothers (EPDS < 10) as non-depressive mother group were included. Ten non-labored, non-depressive women were also included as a normal control group. The subjects were evaluated with the State Trait Anxiety Inventory (STAI)-X1, the Visual Analogue Scale (VAS) and the Depression Adjective Checklist-Korean version (K-DACL) and EEG twice before and after the music sesssion with the length of twenty minutes and thirty two seconds. The statistical analyses were done for A1 score (log R - log L) which were computed from the alpha powers at F3 and F4. Results No significant difference was noted in demographic data among all three groups. The postpartum blues group had higher scores in the STAI-X1, the VAS and the K-DACL compared to the other groups at baseline, and their A1 scores were lower than those of only normal controls. There was a statistically significant increase of A1 score only in the postpartum blues group after the music session. Conclusion This study suggests that the mothers with postpartum blues may have a frontal EEG asymmetry which is possibly associated with their depressive mood, and the music session can affect the frontal asymmetry positively.

The second edition of the Anglo-American Cataloguing Rules (AACR 2) was published in December 1978. In 1974 representatives Qf five bodies from Canada, the United Kingdom and the United States established the Joint Steering Committee for Revision of AACR, and set the aims, structure, and content of AACR 2. Although the goal of a single text for Britain and North America was achieved in AACR 2, the American library community expressed concern about cost-effectiveness of adoption of the new code, and consquently the LC implementation plan called for some minor departures from AACR 2. LC's plan to depart from a number of provisions of the new code will cause a continuation of the problems presented by past practices of superimposition. The purpose of this paper is to examine the revisions made in AACR 2 in the hope that it will contribute to efforts of Korean librarians seeking to focus on the major questions requiring discussion and decisions before adoption of AACR 2 by Korean research libraries who have already adopted Anglo-American Cataloging Rules for Western materials. In this paper attempts were made to follow the order of subjects treated in the code, beginning with general revisions, followed by a discussion of each of the parts of the code, the first for bibliographic description and the second for choice and form of access points. The differences between AACR 1 and AACR 2 that will be most significant to cataloguers are compared with examples. Comparative analysis of optional and alternative rules are viewed from a historical background, and their practical applications for the different types of libraries / or materials are discussed. Specifications of the options adapted by the Library of Congress are presented. Adaption of AACR 2 poses continual problems in Korea. It is very important to maintain consistent sets of information consistently presented in the catalogue regardless of its language. The recognition by cataloguers of the urgent need for conformity and campatability of catalogue between Western mateirals and Oriental materials is recommended, if AACR 2 is to be adapted. It would be intolerable for the catalogue users, if different standards of description and headings were to apply in the same catalogue.

Purpose: This study analyzed the names of optical shops currently used in Korea and is to investigate the optical shop names that customers prefer. Methods: We used the 351 names of optical shop all over the country as a sample, and surveyed 296 people aged between 20s~30s in Seoul and Gyeonggi provinces to collect the data. Results: The most used names are currently English names (54.4%) and names of with 2 syllables (30.5%) and 3 syllables (32.5%). For more than 4 syllables, the names included Eye (26.0%) and Glasses (24.3%) are being used a lot. For the name awareness, Korean names (63.0%) was the highest and followed by 1syllable (34.5%) and 5 syllables (20.9%). Conclusions: For the improvement of optical shop awareness, Korean name with 1 to 3 syllables and words related glasses are recommended.

The purpose of this study is to provide considerations through investigation and analysis about non-computer major learners' difficulties in computational thinking education. In recent, the importance of human resources development in convergence based on computational thinking is increasing internationally and a Korean university is selecting CT as a mandatory subject. I taught CT with Scratch at C university in Seoul for two semesters in 2014 and investigated and analyzed what difficulties non-Computer majors felt in the process of CT education. The result showed they felt the following some difficulties in order: the concept of variable and list; to think a idea and implement it; which commands should be selected. The pleasure and the interest can be apply to decrease difficulty, because they affect self-programming ability and self-CT capability each other statistically. Although Scratch is an easy and an intuitive programming language, it is needed to consider to provide appropriate learning time to student for using and applying commands.

There are tries to unite through consilience in many fields. Interdisciplinary research is an instance of those. Linguistic studies called linguistic informatics or quantitative linguistics is a field of interdisciplinary research related with statistics linguists have studied chiefly statistics and linguistics. In the statistical aspect, there is need to supplement somewhat of the result of researches by linguists. This study shows statistical method can supplement insufficient objectivity in linguistic studies, and examines the way to raise a degree of completion of interdisciplinary research on statistics and linguistics. This study also shows an introduction and application of the statistical method can be useful for the deduction of objective linguistic information in linguistic studies.

Globalization brings changes to universities in particular facilitating internationalizing students exchange and curriculum diversification. Such efforts are relatively weak in education college even though the demands are high in students' global learning expectations internally and educational development cooperation from developing countries. The demands of global education arise from the increase of multi-cultural family, the compelling foreign language proficiency and others. The demands of development cooperation arise from the contribution of education to the rapid economic development. However, Korean participation focuses on vocational training which is far from the international norm of basic education provision and carried out without enough educational specialists. Global education and teaching practices in developing countries would substantiate the internationalization of education college while the effectiveness of educational development cooperation would be enhanced after learning the international norms and local knowledge which are learnt from the global education including foreign school practices.

The purpose of this study is to analyze research trends of school library reading programs. Articles on school library reading programs were searched in four major library and information science journals and two journals specialized in reading, which resulted in total 138 papers. First article was published as early as in 1978, and after a long lull period, researches began to mushroom in 2002 and proliferated between 2013 and 2015. To identify reading programs by type, research on curriculum-linked programs including library assisted instruction and information literacy instruction accounted for 44.9%, whereas programs for promoting library use and reading interest provoking came up with a small research volume. Interdisciplinary convergence involving Korean language education fields and library and information science fields, more concern for developing useful school library reading programs and curriculum-linked programs.

Topic modeling has been receiving much attention in academic disciplines in recent years. Topic modeling is one of the applications in machine learning and natural language processing. It is a statistical modeling procedure to discover topics in the collection of documents. Recently, there have been many attempts to find out topics in diverse fields of academic research. Although the first Department of Industrial Engineering (I.E.) was established in Hanyang university in 1958, Korean Institute of Industrial Engineers (KIIE) which is truly the most academic society was first founded to contribute to research for I.E. and promote industrial techniques in 1974. Korean Society of Industrial and Systems Engineering (KSIE) was established four years later. However, the research topics for KSIE journal have not been deeply examined up until now. Using topic modeling algorithms, we cautiously aim to detect the research topics of KSIE journal for the first half of the society history, from 1978 to 1999. We made use of titles and abstracts in research papers to find out topics in KSIE journal by conducting four algorithms, LSA, HDP, LDA, and LDA Mallet. Topic analysis results obtained by the algorithms were compared. We tried to show the whole procedure of topic analysis in detail for further practical use in future. We employed visualization techniques by using analysis result obtained from LDA. As a result of thorough analysis of topic modeling, eight major research topics were discovered including Production/Logistics/Inventory, Reliability, Quality, Probability/Statistics, Management Engineering/Industry, Engineering Economy, Human Factor/Safety/Computer/Information Technology, and Heuristics/Optimization.

With the shortage of labor force in small and medium-size industries, the Korean Employment Permit System (EPS) continues to bring migrant workers. However, the question remains of the health and safety management of their migrant workers. Considering that a significant part of safety and health problems are caused by migrant workers due to a lack of information on identifying risk and inexperience in the field. Telephone interviews were conducted to investigate the migrant workers' perspectives on workplace safety practices. The survey focused on workers' accident histories, understanding of safety practices, and responding to industrial accidents. A total of 66 accidents occurred among 30 participants. 10 accidents were not reported to the employer (company), which the foreign workers judged to be minor injuries that should not be reported as accidents. 80.0% of the participants expressed dissatisfaction with the PPE they were using. Among various reasons lack of understanding due to language barriers, lack of awareness of the importance of safety, communication difficulties were major reasons for the caused accidents and potential health issues. It is necessary to improve the safety and health support system by providing practical support through specialized educational institutes with experts in the field. A legal framework and a proper safety management system need to be maintained. This study suggests changing the current policy to improve the health and safety of migrant workers by, establishing specialized educational institutes with locally grown foreign experts in the field.
