Sport talent development center have been operating in order to support sports gifted children of the training in the early finding and selecting potential elementary school students for sports. For this purpose, elementary students in grades 2~6 are selected through basal fitness and physique test. However qualitative assessment of the student was not in progress, but depending on current physique and fitness totally sports talented children were selected. Therefore this study was to develop a tool to determine giftedness based on the observation method to assess the athletic potential of gifted children based on Yoon's competition intelligence(2011). For this purpose of study, sub-factors were extracted through expert consultations. Based on the extracted sub-factors, such as training intelligence, learning ability practical intelligence were extracted for practical intelligence, and finally 16 evaluation questions were proposed to evaluate sports talented children. Proposed questions will be helpful for quality evaluation of sports gifted children, as well as using as a method for discovering sports gifted children.

According to resource based view, knowledge is regarded as a salient factor to improve an organization's efficiency in the current fast-changing business environment. Knowledge management (KM) may encourage employees to share and exchange knowledge in the organization in order to improve and sustain a competitive advantage over other companies. The proposed research model examines the impacts of KM performances' antecedents on an employee's absorptive capacity. This study identifies KM performances as employee's satisfaction about KM and shared knowledge quality. This study considers KM performances as the major determinants that enhance his/her absorptive capacity. This study also investigates the key antecedents of KM performances. The research model posits extrinsic reward, intrinsic reward, and relational reward as the KM performances' antecedents. Furthermore, this study examines the difference of the antecedents' effects in terms of firm's type. The proposed research model was tested by using survey data collected from 1,103 employees of 2 public enterprises and 907 employees of 5 private enterprises. The findings of this study showed that employee's satisfaction about KM and shared knowledge quality play a significant role in enhancing employee' absorptive capacity. Extrinsic reward only significantly influences employee's satisfaction about KM, whereas both intrinsic and relational rewards serve as the salient antecedents of improving both KM performances. The results also shed light on the moderating role of firm's type. Theoretical and practical implications of this study are discussed.

The working concept of the disadvantaged gifted is meant by those who hardly can have a chance to develop one's own gifts because of the environmental conditions and factors. The main purpose of this study is to explore the inherent trait of the music giftedness, which is composed of musical ability, creativity, and task commitment. Grounded upon the phenomenal research, this study purposefully samples ten disadvantaged students who participated in the arts gifted camp hosted by Korean National Research Institute for the Gifted in Arts. Thus, it explores the inherent traits of the disadvantaged gifted by coding, segmenting, and analyzing the interview with ten disadvantaged, and the evaluation reports of the expert group. The inherent trait of music giftedness of the disadvantaged gifted is shown as this: the inherent trait of the disadvantaged gifted in music is closely interrelated with one's own concept of giftedness. Whereas they show the high motivation and task commitment, they are hardly observed to have the creativity in their musical activities and learning. Finally, this study give a proposition for the strategy to stimulate and improve the inherent trait of the disadvantaged gifted in music: the importance of parents education and parent screening, meta-cognitive skills, the leaning-based creativity education, and the significant role of intrapersonal catalyst.

문서 클러스터링은 정보검색 시스템에서 검색과정의 효율성을 향상시키기 위해서 많이 사용된다. 기존의 K-means 클러스터링과 같은 거리-기반 접근 방법은 거리에 대한 척도를 정해야 하는 문제가 있고, 또한 전체 자질 공간에서 지역적 특성에 민감하기 때문에 문서 내에 노이즈가 존재할 경우 만족스러운 결과를 내지 못할 수 있다. 그리고 기본적으로 문서 데이터는 희소성(sparseness)을 가기 때문에 정규 분포를 가정한 mixture 모델을 적용하기도 어려움이 있다. 본 논문에서는 Helmoholtz machine에 의한 문서 클러스터링 방법을 제안한다. 제안되는 방법에서는 하나의 문서를 어떤 내재적인 요인(factor)들의 다양한 결합에 의한 결과로 가정하는데, 이 때의 요인은 주제어 집합 또는 적어도 의미적으로 유사한 단어들의 집합이다. 그리고 기본적으로 Helmholtz machine은 이진 데이터를 다루는데, 텍스트 문서에 나타나는 단어들의 빈도를 고려하기 위해 수정된 Helmholtz machine을 제시한다. TREC-8 adhoe 데이터와 20 Newsgroup 문서 집합에 대한 클러스터링 실험 결과, 제안된 방법이 K-means 알고리즘에 비해 우수한 성능을 보였으며 주제어 추출을 통해 문서 집합의 전체 내용 파악을 용이하게 하는 특성이 있었다.

The purpose of this study was to identify the effects of clinical nurses' intrinsic motivation, affective commitment, and turnover intention on organizational performance. Participants were 189 nurses currently working at four general hospitals in C city. Data were collected by a self-report questionnaire and analyzed by using the SPSS/WIN 18.0 program with descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and multiple regression. Mean scores were as follows: intrinsic motivation($3.02{\pm}0.57$), affective commitment ($3.47{\pm}0.71$), turnover intention ($3.30{\pm}0.59$), and organizational performance ($3.37{\pm}0.52$). Organizational performance was significantly correlated with intrinsic motivation, affective commitment, and turnover intention. Nurses with higher affective commitment and intrinsic motivation showed higher organizational performance, where as higher turnover intention was correlated with lower organizational performance. The factors that influenced organizational performance were affective commitment(${\beta}=.42$), intrinsic motivation(${\beta}=.36$), and turnover intention(${\beta}=-.11$), with an explanatory power of 51.6%. Results of this study indicate the need to evaluate and manage the significant predictors of organizational performance. Further studies are needed to identify the relationships between clinical nurses' intrinsic motivation, affective commitment, turnover intention, and organizational performance.

One of the most significant changes is the paradigm shift from teacher-centered learning to learner-centered learning. Along with this paradigm shift, understanding of characteristics of e-learners who are both system users and learners is needed. Before suggesting a comprehensive framework, this study proposes research model that can improve a learning performance using the flow theory. The results show that intrinsic interest and focused attention are significant predictors of learning performance. Especially, intrinsic interest is more important on learning performance than focused attention. Information quality and skill are found to be strong predictors of the intrinsic interest. Also, perceived ease of use, skill and computer self-efficacy are strong predictors of the focused attention.

The purpose of this study was to stimulate the online word-of-mouth advertising by developing the concept of word-of-mouth constraint factors and measurement tools in connection with the SNS advertising on social networks. To achieve the objective of this study, this study was conducted in 3 phases. First, the exploratory investigation(target group interview, in-depth interview, and expert interview) was performed to determine the concept and scope of the word-of-mouth constraint based on literature study and qualitative investigation method. Second, the reliability and validity of the measurement questions were verified through the survey in order to refine the developed measurement items. Third, the predictive validity of measurement items was verified by examining the relationship with other major construct concept for which the developed measurement items were different. Based on the results of study, 6 components and a total of 23 measurement questions for those components were derived. Each was called intrapersonal and interpersonal constraint(psychological sensitivity, compensatory sensitivity, and other person assessment), structural constraint(reliability, informativity, and entertainment). We developed the measurement questions related to word-of-mouth constraint based on qualitative study and quantitative study and holistically examined the social and psychological, environmental interruption factors acting as the word-of-mouth constraint factors for SNS advertising in terms of SNS achievements and evaluation from the perspective of word-of-mouth constraint. The results will lead to creation of basic framework for systematic and empirical research on the online word-of-mouth constraint and to achievement of effective SNS word-of-mouth advertising.

It seems crucial for entrepreneurship researchers to study how individual creativity is influenced by a number of entrepreneurship related traits. This is because individuals aiming to become entrepreneurs by launching their own start-ups need to enhance their creativity level to compete successfully in the target market. In the field of entrepreneurship studies, however, there is no literature about exploring the relationship between individual creativity, and entrepreneurship related constructs such as intrinsic motivation, parasocial interaction, prosocial motivation, and perspective taking. In this sense, our proposed research model focuses on filling the research void like this. To verify the proposed research model. we collected valid data from college students. To add rigor to our study, we allowed participants to view a talk show content where a successful entrepreneur was telling his story. Empirical test results were robust statistically enough to prove the validity of our proposed research model.

In this paper, we estimate systematic risk from credit migration (or transition) matrices under "Asymptotic Single Risk Factor" model. We analyzed transition matrices issued by KR(Korea Ratings) and concluded that systematic risk implied on credit migration somewhat coincide with the real economic cycle. Especially, we found that systematic risk implied on credit migration is better than that implied on the default rate. We also emphasize how to conduct a stress test using systematic risk extracted from transition migration. We argue that the proposed method in this paper is better than the usual method that is only considered for the conditional probability of default(PD). We found that the expected loss critically increased when we explicitly consider the change of credit quality in a given portfolio, compared to the method considering only PD.
