Music industry is considered as a creative industry, which tends to locate within a city. However, there is very few paper analysing spatial patterns of music industry in Korea. This study aims to understand music industry's value chain and its location pattern; whether it is clustered or dispersed. In detail, music industry contains five sub-industry: planning, manufacturing, distribution, sales and performance. Locational pattern of each sub-industry is tested by GIS and hot spot analysis. There are several findings from this research. First, value chain of music industry make clusters and have a spatial autocorrelation. Second, the result shows that music industry makes a hotspot area at Gangnam, Guro, Mapo and Jongro-Junggu.

In study I, Domain-Specific Risk Taking Scale(DOSPERT) was translated into Korean and was validated that it had 6 factors structure and showed adequate reliability and validity, using the data had been collected from 438 participants. In study 2, two research problems were examined using the data had been collected from 497 participants who were different from study I. First, the mediation effect of sensation seeking and perceived benefit on the relationship between narcissism and risk-taking were examined. Using path analysis, it found that sensation seeking and perceived benefit mediated the relationship between NPI narcissism and risk-taking fully, and between PNI narcissism and risk-taking partially. Seceond, the moderate effect of contingencies of self-worth(CSW) on the relationship between perceived benefit-risk and risk-taking was examined. Using multi-group analysis, it found that virtue CSW moderated the relationship between perceived benefit-risk and total risk-taking, various CSWs moderated the relationships between perceived benefit-risk and 6 sub domains of risk-taking. These results were compared with previous studies of risk-taking and discussed the relevance of the narcissistic type.

The value that students consider important in math learning may vary depending on the student's socio-cultural background and personal experience. Although socio-cultural backgrounds are very diverse, I considered overseas vs domestic Koreans, and secondary school levels as variables in terms of students' educational experiences. Overseas students had a lower perception of the value in mathematics than domestic students, especially about understanding mathematics knowledge and the value of the latest teaching and learning methods. Middle school students perceived the value of mathematics as an activity higher than that of high school students, and high school students perceived student agency as a higher value than middle school students. In addition, I considered meta-affect as one of the individual students' experiences, finally meta-affect was a variable that could explain value perception in math learning, and in particular, affective awareness of achievement, affective evaluation of value, and affective using were significant. From the results, I suggested that research on ways to improve the value and the meta-affect in math learning, test to measure the value of students in math learning, the expansion of research subjects to investigate the value in math learning, and a teacher who teaches overseas Koreans are needed.

교환바이어스(exchange bias)현상은 강자성과 반강자성의 접합계면에서 강한 상호 교환결합력에 의해 발생하는 것으로 알려져 있다. 이 현상은 1956년 Meiklejohn과 Bean에 의해 CoO 층으로 둘러싸인 Co 입자에서 발견된 이후, 강자성과 반강자성의 접합계면을 가지는 다층 박막에서의 교환바이어스에 대한 연구가 진행되어왔다. 이는 강자성/반강자성 박막의 교환바이어스 특성을 이용하여, 강자성 박막의 스핀방향을 고정시킬 수 있기 때문이다. 이러한 교환바이어스 특성은 하드드라이브의 고밀도 자기헤드소자 및 비휘발성 자기메모리소자에 응용되어지는 등 경제적 가치를 갖는 기술적인 면과 교환바이어스라는 자기특성의 학문적인 가치로 인해 이 분야에 대한 집중적인 투자와 연구가 이루어지고 있다 최근에는 교환바이 어스 현상의 원인과 형성기구에 대한 연구가 활발히 진행되고 있다. 그러나 강자성과 반강자성 박막의 단거리 상호 교환결합력에 의한 교환바이어스 현상은, 계면의 원자구조, 자기구조 및 각자성층의 여러 가지 인자들에 대해서 지속적으로 연구되고 있다. 본 연구에서는 Helmhertz 코일의 진동샘플형 자력계(VSM)을 이용하여 Si 기판위에 증착된 NiFe(10nm)/FeMn(t)/NiFe(10nm) 다층박막에서 FeMn층의 두께에 대한 각각의 교환바이어스 현상을 조사하고 사잇층 FeMn층의 surface를 Ar ion beam etching하여 etching 조건에 따른 교환바이어스를 비교분석 하고자 한다.

The purpose of this research is to increase an understanding of social media users and construct a strategic, administrative foundation to measure the efficiency of communicating with them by validly classifying components of social media users' value expectation(VE). Reviewing prior research, in-depth interviews as qualitative research, pre-test and main survey as quantitative research are conducted. The result of quantitative research shows that social media users' VE was categorized in terms of utilitarian, hedonic, relational, self-evident, ethical, system functional, participative, self-ostentatious, and self-hiding perspectives. The significance of this study is as follows: 1) It views communication, psychology, marketing, media and etc. related fields from an integrated perspective. 2) It segments and categorizes social media users' VE from a practical perspective. 3) It contributes to constructing a foundation to predict, confirm, and manage social media users' attitudes from an administrative perspective. Thus, this research will aid future research on social media users' attitude using the constructed VE components as variables and future research that uses this as a basis to find media effects.

In this article, a fairly extensive literature review was conducted to depict the current status of academic motivation and its developmental trend among Korean adolescents. The focal factors were perceived competence and autonomy which have been considered as major determinants of academic motivation. Theoretical frameworks adopted were self-efficacy theory, expectancy-value theory, and self-determination theory. Empirical studies conducted in Korean educational settings during the past decade were the target of the literature review. Results of the literature analysis revealed that, in general, there was a decreasing tendency in perceived competence from elementary to middle school which followed by a slight increase after entering high school. Similar trend revealed in the development of autonomous motivation, in that middle and high school students' intrinsic motivation levels were lower than that of the elementary groups. The amotivational tendency was increased as the grade level proceeded toward high school, which requires attention from educators. Discussion was followed in an attempt to provide plausible interpretations for this undesirable current status of Korean adolescents' academic motivation and to suggest implications for possible remedial actions both in pedagogical perspectives and students' well-being.

The study identified 1,500 adult consumers aged 25-54 years with life insurance within the last year as three groups, top, middle and bottom of need recognition, and demonstrated differences in insurance and finance perception and socioeconomic value perception. In particular, the study sought to identify the influence of socioeconomic value recognition factors in addition to overall recognition factors related to insurance and finance, the number of insurance held and insurance satisfaction. Overall recognition factors related to insurance and finance were classified as 'recognition of insurance as a means of professional management and finance', 'self-directed insurance design and contract' and 'recognition of economic burden on insurance'. Socioeconomic value recognition factors were divided into 'socioeconomic self-sufficiency', 'work-life value pursuit' and 'economic value pursuit'. We identified factors that affect the recognition of a higher need for insurance needs as a higher recognition of need for insurance needs. In particular, the most influential factor for the median group was the recognition of insurance as a professional management asset-tech product, and the upper group was found to be a work-life balance factor. The second influential factor was self-directed insurance design and contract factors for both groups. In order to increase the rate of insurance subscription in the future, insurance should be recognized as an essential product to pursue work-life value, and continuous improvement in information exploration conditions for consumers to explore information and compare products will be important to revitalize the insurance market.
