The purpose of this study is to analyze user behaviors of books in detail based on circulation data in an academic library. It analyzes circulation patterns of books for ten years from 2006 to 2015, which are surprisingly similar every year. Each pattern follows 'Loan books 20/50 rule' that 20% core collection occupies 50% of its circulation every year. This clarifies users' circulation patterns are highly consistent and very expectable. Also, using the cumulative distribution of book age, it defines the half-life of books and suggests the mathematical formula to measure it. Circulation patterns of the whole loan book and core collection for ten years are very different in terms of subjects, user groups, and divisions. This indicates that core collection plays a significant role in analyzing circulation statistics and usage patterns for the efficient collection development in the future.

This paper examined how the millennial generation consumes mobile news through social networking sites with regards to user patterns, preference topics and news values, and whether news topics and news values may influence their overall mobile SNS news consumption and interactivity. The findings show that more than 2/3 of respondents consumed mobile SNS news at least once everyday for 30minutes to one-hour. Male millennials tended to use Facebook and Kakao-talk more than female. While the portal site was the most accessed channel for consuming mobile news, SNS was the second, more than the combined use of national daily papers, TV, and internet newspapers. The respondents' demographic characteristics and news topics also affect the form and degree of news interactivity. With regards to their preferences and prioritization of news values, millennials tend to perceive 'impact' and 'usefulness' as being most important, despite the differences of their demographic characteristics. They also preferred those news values most. There were significant differences in terms of preferred news topics according to the demographics' characteristics.

Studies on the SNS political participation have covered issues of SNS effect on political participation, electoral campaigns, and the public sphere. Such issues as characteristics of SNS political participation, the characteristics of SNS users, SNS effect on the political participation, active SNS political participants, and the impact on young people's political participation, etc. have been studied in the area of political participation effect. On the election issues, SNS impact on election turnout, voting behavior, and the election results were main research topics. Finally, the research on the public sphere mainly discussed topics of quality of SNS information and social fragmentation phenomenon. What is commonly observed across all the three subjects is that the conflicting claims appear to almost all the topics. These contradictory findings are likely to occur because variables of real politics are not fully taken into account and research variables are not strictly manipulated. We can get more accurate research results in the study of SNS political participation when we conduct cross-national research reflecting the context of real politics and also designing independent variables more in detail and elaborately.

The purpose of this study was to understand how participants' experiences of participating in self-sufficiency projects were. To do this, we analyzed phenomenological methods using in-depth interview data of 48 participants from the Central Self-Sufficiency Foundation, which is qualitative data of the "Project for Strengthening Self-Support for the Working Poor". The study revealed 214 meaningful statements and general re-statements, 24 themes, 9 themes cluster, and 5 categories. Participants' experience was found to be forced work, felt alienated from the self-sufficiency business, and could not receive a clear vision for the future. At the same time, the experience of participating is an opportunity for motivation for change in one's own life, and the essence of becoming a stepping stone to move forward for self-reliance has been derived. Based on the results of this study, we proposed a practical policy task to create a positive expectation effect.

To visualize the characteristics of vertical seawater temperature data, in the ocean having 3D spatial characteristics, 2D thematic maps like horizontal seawater temperature distribution map at each depth layer and 3D volume model using 3D spatial interpolation are used. Although these methods are useful to understand oceanographic phenomena visually, there is a limit to analyze the spatial pattern of vertical temperature distribution or the relationship between vertical temperature characteristics and other oceanic factors (seawater chemistry, marine organism, climate change, etc). Therefore, this study aims to determine the spatial distribution characteristics of vertical temperature profiles in the South Sea of Jeju by quantifying the characteristics of vertical temperature profiles by using an algorithm that can extract the thermocline parameters, such as mixed layer depth, maximum temperature gradient and thermocline thickness. For this purpose spatial autocorrelation index (Moran's I) was calculated including mapping of spatial distribution for three parameters representing the vertical temperature profiles. Also, after grouping study area as four regions by using cluster analysis with three parameters, the characteristics of vertical temperature profiles were defined for each region.

The purpose of this study is to identify the factors influencing conflict transition through the conflict transition process experienced by college graduates with early careers. The participants of this study were in-depth interviews with a total of 8 young people aged 25-34 who graduated from college and found their common subjects in all cases. As a result, the topics such as 'lack of recognition and compensation', 'unfairness of supervisor', 'characteristics of job (interdependence, autonomy)' were derived. 'Lack of recognition and compensation' brought about a sense of skepticism about the idea that even though they worked hard, they could not be recognized. And it caused a conflict transition. When the participants felt the 'unfairness of the supervisor', the task conflicts were further amplified and it transfer to relationship conflict. Among the characteristics of 'job characteristics', when highly interdependent occupations were carried out, conflict transition was shown and conflict levels were high. On the other hand, the work environment with job autonomy showed job satisfaction and did not show conflict transition. This study has an academic significance in that it revealed the types of conflicts and conflict transfer factors experienced in early career status of college graduates. In addition, this research have the practical implications to improves the participants' understanding of the conflict transfer through actual scene in the workplace.

We analyzed the characteristics of the habitat environment for the Seonam study area in Ulsan, the southern shore of the East Sea using bathymetry and seafloor environment data. The depth of the study area ranges from about 0 m to 23 m. In the west of the study area, the water depth is shallow with a gentle slope, and the water depth becomes deeper with a steep slope in the east. Due to the right-lateral strike-slip faults located in the continental margin of the East Sea, the fracture surfaces of the seabed rocks are mainly in the N-S direction, which is similar to the direction of the strike faults. Three seafloor types (conglomeratic-grained sandy, coasre-graiend sandy, fine-grained sandy) and rocky bottom area have been classified according to the analyses of the bathymerty, seafloor image, and surface sediment data. The rocky bottom areas are mainly distributed around Seaoam and in the northern and southern coastal area. But the intermediate zone between Seonam and coastal area has no rocky bottom. This intermediate area is expected to have active sedimentation as seawater way. The sandy sediments are widely distributed throughout the study area. Underwater images and UAV images show that Cnidarians, Brachiopods, Mollusks are mostly dominant in the shallow habitat and various Nacellidae, Mytilidae live on the intertidal zone around Seonam. Annelida and Arthropod are dominant in the sandy sediments. The distribution of marine organism in the study area might be greatly influenced by the seafloor type, the composition and particle size distribution of the seafloor sediments. The analysis of habitat environment mapping with bathymetry, seafloor data and underwater images is supposed to contribute to the study of the structure and function of marine ecosystem.

The purpose of this study is to investigate the trends of the start-up research in Korea. To accomplish this, meta-analysis was carried out using text mining methodology by dividing the entrepreneur-related master's and doctoral theses registered in RISS into the first term of entrepreneurship research by 2009 and the second term of entrepreneurship research from 2010. As a result of this study, it can be seen from the three different analysis that the entrepreneurship education and government policy and support are the subject of continuous research topics in the whole period and that the researches on small business start-ups have been studied continuously and conducted more in the second half. In addition, empirical analysis is strengthened in the latter stage of entrepreneurial research. The TF-IDF analysis reveals that many researches on veterans have been carried out in the field of entrepreneurship research, and in the latter period, it was found that many studies related to the elderly were conducted with cultural contents and aging society. In addition, research on brand-related research has been carried out throughout the entire period, and research on venture-related research, characteristics of entrepreneurs, entrepreneurship motivation and start-up strategy have been conducted a lot and female entrepreneurship was also studied. In the latter period, we have emphasized entrepreneurial achievements and found that research on start-ups such as industry-academia cooperation, start-up investment, and social enterprise diversified. This study is meaningful to apply the method which is becoming a recent issue such as text mining and topic analysis to the meta-analysis related to start-up. Future research will need to be undertaken on a variety of more detailed topics related to entrepreneurship.

이 연구는 강화경판 『高麗大藏經』에 入藏된 『合部金光明經』과 13세기 중엽에 간행된 것으로 추정되는 口訣本 『合部金光明經』의 조성에 참여한 刻成人에 대해 살펴본 것이다. 국가적·범종파적 사업으로 전개된 각성사업에 『합부금광명경』이 조성되고 있는데도 불구하고, 구결본 『합부금광명경』 조성에 참여한 이들은 각성사업과 어떤 관련성을 갖고 있는지 검토해 보았다. 이에 『고려대장경』에 입장된 『합부금광명경』과 구결본 『합부금광명경』을 상호 비교해 본 결과 경전의 내용과 板式, 그 구성 체계가 相異한 본이었다. 그리고 彫成에 참여한 각성인을 조사해 본 결과 『고려대장경』에는 ‘부령’이었고, 구결본은 ‘存植’, ‘立成’, ‘正安’, ‘孝兼’ 등이었다. ‘存植’, ‘正安’, ‘孝兼’은 고종 24년부터 16년간 전개된 각성사업에 참여한 각성인들과 동일 인물이었다. 특히 ‘孝兼’은 자신을 비구라고 밝힌 점으로 볼 때 당시 활동하던 刻字僧으로 파악된다. ‘存植’과 ‘正安’은 고종 33년에 간행된 『禪門三家拈頌集』과 13세기 중엽에 간행된 『圓覺類解』, 『弘贊法華傳』의 조성에도 참여하고 있는 것으로 보아 전문 刻手로 보여진다. 그래서 각성사업에 참여한 각성인들은 각자의 여건에 따라 활동하고 있음을 알 수 있다. 『合部金光明經』은 『妙法蓮華經』·『仁王經』과 함께 호국삼부경 중의 하나로서 고려시기에 수시로 간행되고 있었다. 『금광명경』은 국가를 보호하고 내우외환을 소멸시키기 위해 왕실을 비롯한 관료층들이 깊이 존신하고 권장하려 하였던 불교 경전이었다. 특히 대외관계상의 위기상황에는 『금광명경』을 바탕으로 하는 功德天道場이라는 호국적 성격의 법회를 개최되고 있었다. 따라서 『합부금광명경』의 간행 배경에는 『고려대장경』이 국왕을 정점으로 반외세력인 몽고군을 격퇴시키고, 또 최씨무인정권으로부터 왕권을 회복시키고자 시대적 분위기가 적극 반영되어 있다. 구결본 『합부금광명경』의 간행은 민족적·국가적 사업이었던 각성사업에 적극 동참하면서 현실을 직시하고 고려 불교의 창조적 발전은 물론 외세의 침략으로부터 조국을 지키고자 하는 호국의식을 바탕에 두고 있었다. 〔주제어〕『高麗大藏經』, 『合部金光明經』, 刻成人, 최씨무인정권, 護國經

In this research we diagnosed the actual status of the 7th National science elective curriculum and suggested a way to select and organize the content of the new science elective curriculum. The first science education reform was grounded in the structuralism where the structure of discipline was valued above everything else. On the other hand, the second science education reform suggested alternative interpretations of students' opportunity to learn, putting a brake on the structuralist thinking. According to the survey result, the majority of the science elective courses are in need for revision because the contents are overcrowded, too difficult in light of students' learning readiness, failed to draw students' interest in science, and are overlapped and repeated among the 10th grade science, high school science I and II. In particular, Earth Science II and physics II are the most unfavorable courses among students. Thus, we recommended a fundamental change be made in the new curriculum in addition to the optimization of the content. In this paper, we suggested 'topic-centered content organization' for the science elective course I, i.e., Physics I, Chemistry I, Biology I and Earth Science I that is designed for both science track and non-science track students. Since curriculum provides students with an 'opportunity to learn', a curriculum study should focus on what the 'opportunity to learn' is that students ought to be offered. Based on the result of this study, we recommended one way to select and organize the content of high school elective curriculum.
