  • Astronomy areas in the elementary science textbooks of Korea and the U.S.A. have been compared to find advantages and disadvantages of Korean textbooks. The analysis objects are the 7th national curriculum science textbooks for Korea and the Macmillan McGraw-Hill(MMH) science textbooks for the U.S.A. The results are as follows: First, in contexts, Korean science textbooks contain mostly inquiry activities and partly reading materials. However, MMH ones contain mostly explanations including photographs, related activities, and various reading materials. Second, in the contents and order, the observation activities of constellations are emphasized in Korean science textbooks, while the MMH ones explain solar system up to the universe in details. In addition, Korean science textbooks deal with one subject only once during the whole elementary course while MMH ones deal with one subject repeatedly in several grades. Third, in the frameworks of the international mathematics and science study (TIMSS) 2007, Korean science textbooks do not introduce some contents presented in TIMSS 2007, whereas MMH textbooks introduce every one of them in time. Fourth, the major subjects such as change of moon phases, constellations, the solar system, and change of seasons are handled independently in Korean science textbooks without strong correlation, while they are systematically done related with the rotation and the revolution of the earth in MMH ones.

  • Purpose - Studies of mechanism as a competitive strategy, a relatively new field in the study of strategic management research, has recently drawn the attention of the business management scholars. The literature has so far proposed the subjective-based view, environment-based view, and the resource-based view in its analyses of firm management. Hence, it is highly likely for the firm management to be reasonably thought of as a combination of and interaction among the three key elements of subject, environment, and resources this is the mechanism-based view (MBV). It is reasonable to consider firm management to be the combination of and interaction among the three key elements of subject, environment, and resources. The overall dynamic process that integrates these three elements and creates functional harmony is identified as the mechanism, the principle of firm management. Much of the extant literatures on MBV has mainly focused on case studies, a qualitative approach prone to subjectivity of the researcher, although the intuition from the study may lead to meaningful insights into a firm-specific mechanism. This study's focus is also on case analysis, but it still attempts a quantitative approach in order to reach a scientific and systematic understanding of the MBV. Research design, data, and methodology - I used both a qualitative and quantitative approach to a single model, given the complexity of the innovation processes. I conducted in-depth interviews with POSCO employees-20 from general management, two from human resources, eight from information technology, five from finance and accounting, and five from production and logistics management. Once the innovative events were selected, the interview results were double-checked by the interviewees themselves to ensure the accuracy of the answers recorded. Based on the interview, I then conducted statistical validation using the survey results as well. Results - This study analyzes the building process of innovation and the effect of the mechanism pattern on innovation by examining the case of POSCO, which has survived over the past 21 years. I apply a new analytical tool to study mechanism innovation types, perform a new classification, and describe the interrelationships among the mechanism factors. This process allows me to see how the "Subject"factor interacts with the other factors. I found that, in the innovation process of the adoption stage, Subject had a mediating effect but that the mediating effect of resource and performance was smaller than the effect of Subject on performance alone. During the implementation stage, the mediating effect of Subject increased. Conclusion - Therefore, I have confirmed that the subject utilizes resources reasonably and efficiently. I have also advanced mechanism studies: whereas the field's research methods have been largely confined to single case studies, I have used both qualitative and quantitative methods to examine the relationships among mechanisms.

  • This study was carried out on specialized library librarians to investigate the status and overall satisfaction of specialized services and to compare the degree of importance and satisfaction of specialized subject data, specialized service places, specialization programs, specialized subject area facilities and environment based on ISA technique in order to derive problems and improvement measures for the operation of specialized libraries. As results, first, it was found that a specialized library subject should be selected based on the characteristics, history, and resources of the library location as well as based on the demand survey of the local residents and users. Second, based on the appropriate program type of specialized subject and the results from users' demand surveys, specialized libraries should develop different types of experience-type, lecture-type, view-type and the likes. Third, specialized library space types can be divided into integrated type, independent-in-integration type, and independent type. Even though it is most ideal to provide independently specialized space, the space must be constructed considering the circumstances and subject of specialization of each library. Fourth, specialized libraries should have at least one dedicated specialist in the corresponding subject. Dedicated specialists should provide lending and reference services related to the specialization such as tidying, browsing, reading and operating specialized programs. And a dedicated specialist must be an expert in the specialized subject and also a librarian who is responsible of the general library operation.

  • This study is a case study in which collection performance evaluation was attempted using key performance indicators presented by EBSM or collectionHQ, taking three public libraries located in Geumjeong-gu, Busan as examples. Focusing on the collection performance evaluation, which evaluates the performance of the collection, not only the evaluation of individual libraries, but also the differences in the evaluation results of libraries were reviewed. The key performance indicators used are grubby items, dead items, popular author provision, popular subject provision, overstocked subject areas and understocked subject areas. The main analysis results are as follows. First, in the evaluation of the grubby items, the ratio of grubby items out of all items in all three libraries was low. Second, in the case of all dead items, the ratio was high in all three libraries, It exceeded the base value suggested by collectionHQ. Third, the Top 10 popular authors were identified, and there were differences among libraries. Fourth, in the evaluation of provision of popular subject areas, all three libraries had almost no popular subject areas. Fifth, in the evaluation of overstocked subject areas, there was no overstock at Geumsaem Library, but many at Geumjeong Library and Seodong Library. Sixth, in the subject area evaluation of understocked inventory, only Geumsaem Library showed a lack of inventory.

  • Purpose: This study is a descriptive study to investigate the relevance between pathophysiological subject and examination workbook items for national nurse licensure examination in South Korea and the United States. Methods: Eight registered nurse licensure examination workbooks published by the Korean nurses association were used for the analysis. Saunders comprehensive review for the national council licensure examination (NCLEX-RN) was used for analysis of those in the United States. The relevance between the subjects in the standard syllabuses of pathophysiology and the registered nurse licensure exam items of these workbooks in South Korea and the United States respectively was analyzed. Results: The Relevance rates in South Korea and the United States were : fundamentals of nursing 6.34% vs 32.12%, adult nursing 25.5% vs 25.92% child health nursing 7.81% vs 21.7%, woman health nursing 5.1% vs 17.07% psychiatric mental health nursing 2.7% vs 7.32%, and community health nursing 0.9% vs 0%. Conclusion: the relevance in pathophysiology between the registered nurse licensure exam in South Korea and the United States was high in adult nursing and fundamentals of nursing (especially in the United States). In developing integrated registered nurse licensure exam questions, we should consider pathophysiology as an important subject.

  • This study explored the organization of high school Home Economics (HE) selective curriculum for the Fourth Industrial Revolution. We critically review the change process of HE curriculum as well as problems based on the understanding of the Fourth Industrial Revolution. The results were as follows. First, regarding the characteristic consistently shown in the revision process of high school curriculum, the huge increase of the number of subject organized resulted from the intensification of the selective-centered curriculum strengthening the choice for school and students. However, HE was reduced to some 'Technology-Home Economics' subject and a single subject 'HE Science' as a selective subject was subsequently combined with Technology after the $7^{th}$ curriculum period. Consequently, HE hard to organize the career-focused curriculum, emphasized by the revised 2015 curriculum due to the insufficient number of subjects. Second, the choice of HE in high school curriculum should be expanded as measures to organize the HE curriculum of high school to cope with changes that result from the Fourth Industrial Revolution. For the operation of the career-focused curriculum, career selective subjects and specialized subjects should be more diversely established. In accordance with changes in a future society that results from the Fourth Industrial Revolution, the HE education community should be prepared in advance to be organized as a selective subject when revising a subsequent curriculum, by newly establishing subjects necessary to students through collective intelligence and deliberation with pedagogists and scholars for subject content as well as by producing/getting approval from government-recognized textbooks.

  • PURPOSE: Many studies have reported the improvement of cognition through physical activity among subject with dementia. This study aimed to whether the current studies supports that physical activity intervention is efficacious on cognitive performance in subject with dementia. METHODS: Two independent reviewers searched National assembly library, RISS, KISS (2005-2015) using the concepts of dementia, exercise, and physical activity. We included randomized controlled trials that examined the efficacy of physical activity in subject with dementia. A meta-analysis was performed to estimate the effect sizes cognition with CMA (Comprehensive Meta-Analysis, version 2.2.064) soft-ware program. Nine randomized controlled trials were included, providing data from 133 individuals and excluding those failing to criteria of this study. RESULTS: The meta-analysis showed that physical activity intervention had a rather small effect sizes of 0.36 (95% confidence interval 0.14-0.59) on cognition performance in subject with dementia. Outcome measurement were MMSE-K (Mini-mental state examination Korean version) and LOCTA (Loewenstein Occupational Therapy Cognitive Assessment). We found heterogeneous among studies and there was difference between the studies (Q = 19.63, d(f)=12, $I^2= 38.88$). CONCLUSION: The present analysis suggests that physical activity interventions have the low effect sizes on cognition performance in subject with dementia Further studies will be required to develop the various programs for improving the cognitive performance in subject with dementia.

  • Purpose: This descriptive study was conducted to compare the teaching status, utilization of the teaching materials, and the need to solve matters of sex education between the school health educators and teachers working in an elementary school in Busan. Method: 182 school health educators and 125 teachers participated in the research. Data was collected using a self-administered questionnaire, and analyzed by frequency and x2 -test using the SPSS WIN 10.0 Program. Results: While school health educators carried out most of the sex education in the extra curriculum and physical education class, teachers did in the regular curriculum and physical education class. Regarding the utilization of the teaching materials on sex education, although the majority of school health educators used the teacher's manual, only a few teachers used it. Most of the school health educators used the ICT teaching materials while only half of the teachers did. Regarding the methods to solve matters on sex education, school health educators responded that a sex-related subject should be combined with a health subject, and an independent sex-related subject was necessary. The teachers, however, responded that it was necessary to secure enough time for sex education, the sex-related subject combined with a health subject was necessary, and there is a need to designate a sex educator. Conclusion: School health educators utilized more teaching materials for sex education and suggested more active methods to solve matters related to sex education. Therefore, school health educators should be more active as sex educators, and the subject of sex education should be adopted as a regular course.

  • Subject classification of thesis units is essential to serve scholarly information deliverables. However, to date, there is a journal-based topic classification, and there are not many article-level subject classification services. In the case of academic papers among domestic works, subject classification can be a more important information because it can cover a larger area of service and can provide service by setting a range. However, the problem of classifying themes by field requires the hands of experts in various fields, and various methods of verification are needed to increase accuracy. In this paper, we try to classify topics using the unsupervised learning algorithm to find the correct answer in the unknown state and compare the results of the subject classification algorithms using the coherence and perplexity. The unsupervised learning algorithms are a well-known Hierarchical Dirichlet Process (HDP), Latent Dirichlet Allocation (LDA) and Latent Semantic Indexing (LSI) algorithm.
