This paper explored the effect of digital epistemology on Christian education. The media of an era determines the type and form of the epistemology of that era, which in turn has a decisive influence on the direction of Christian education in that era. Therefore, it consists of three parts. First, an investigation on the relationship between media and epistemology, second, an investigation on digital epistemology, and third, an investigation on the effect of digital epistemology on Christian education. In this paper, first, from the perspective of McLuhan's media theory, it was discovered that media go beyond simply expanding the our senses and change our perception through creating a new environment and way of life. This paper could characterize digital epistemology in the following four ways through comparison with the traditional epistemology of the print media era: namely "from linguistic to omnisensory epistemology", "from causality to relational epistemology", "from historical to post-historical thinking", and "from interpretive to performative epistemology". In addition, it examined the effects of that digital epistemology on Christian education. Through this study, it found that digital media can act both positively and negatively on the essence of Christian education. Therefore, the task of Christian education in the digital age is to make it a positive function rather than a dysfunctional one, and an opportunity rather than a challenge.

This study identified the cause-and-effect relationship of security management service quality by empirically analyzing whether the performance factors affecting the casino industry are improved when the quality of the security management service is improved. For this, Partial Least Squares (PLS) that can deduce the structural relationship between variables was used. To verify the representativeness of the population, SPSS 19.0 was utilized in a demographic analysis, a independent T-test and Scheffe test. The analysis of the data revealed that the casino industry must preferentially manage assurance, empathy, and security to improve the casino security management service quality, and that, of these, security was the most important factor. To help improve service quality, a theoretical and empirical basis that can consider the importance and priority of individual factors was presented based on the result of this analysis. It also revealed that the security management service is an essential factor for stable business activities of casinos. Further, the importance of the role of the security management service in business strategy formulation for improving the industry performance was recognized through the study results. A service quality improvement method was provided by focusing on the factors that must be preferentially considered for service quality improvement; moreover, implications that can predict the results of such method were presented.

This study applied self-determination theory to investigate the relationships between volunteers' perception of supervisors' autonomy support, volunteering motivation, and persistence intentions among collegiate students. Collegiate volunteers(n=515) involved in volunteer activities completed measures of supervisors' autonomy support, 5 forms regulation, and persistence intentions. Bivariate correlations indicated that volunteer motivation demonstrated an ordered pattern of relationships, such that adjunct points along the regulatory continuum would be more positively associated with on another than distal points. Analyses using structural equation modeling revealed that supervisors' autonomy support was positively related to more autonomous motivation(intrinsic motivation and identified regulation), while was natively associated with amotivation. Amotivation was negatively related with persistence intentions, and more autonomous motivations(intrinsic and identified) predicted grater intentions to continue with volunteer activity for next 6 months. The findings are discussed in light of the self-determination theory.

Since 1950s, the Korean housing market has continually experienced the chronicle lack of housing stock because of lower housing investment in comparison with a population explosion, prompt urbanization and rapid restructuring of family. The Korean housing market have thus been driven not by the pricing model by housing demand-supply chain but by the Korean housing policies focusing on the increase of housing supply and the living stability of the middle or low-income bracket. After all, repetitive economic vicious circle of housing price and the increase of unsold apartments aggravated the malfunction of the Korean housing market. Meanwhile, the Korean construction firms have exacerbated their profitability. Such terrible situations are mainly triggered by the Korean construction firms that weighed on the short-term profits and quick response of the government policy alterations rather than the prospect of housing market Therefore, this research focusing on the dynamics of housing market identified and classified the demand and supply elements that consist not only of housing system structures but also of the environmental elements that affect the structures. Based on the system thinking and traditional theory of consumer's choice, the interactions of these elements were constructed as a causal loop diagram that explains the mutual influences among housing subsystems with feedback loops. This paper describes and discusses about the causes of the dynamic changes in the Korean housing market. This study would help housing suppliers, including housing developers, construction firms, etc., to form a more comprehensive understanding on the fundamental issues that constitute the Korean housing market and thereby increasing their long term as well as minimizing the risk involved in the housing supply businesses.

Companies make decisions with risks such as choosing an investment plan in order to pursue profits. This study explained the decision making of the management of construction companies in South Korea using the tendency to avoid losses in the Prospect Theory. To this end, 20-year financial data of 2,881 companies engaged in real estate development, which have to bear the greatest risk among the construction industry, were collected. The collected companies were roughly classified based on the reference point, and the causal relationship between average return on equity and risk preference by group was empirically analyzed through regression analysis. As a result, it was confirmed that if the average return on equity of a company decreases for the group above the reference point, it tends to select an investment plan with low uncertainty in order not to lose additional money. In addition, it was confirmed that if the average return on equity of a company decreases for the group below the reference point, it tends to select an investment plan with high uncertainty to move to the profit area. This result is exactly consistent with the loss aversion tendency of the Prospect Theory.

Individual characteristics and entrepreneurship are important factors to determine entrepreneurial intentions. Despite this, little attention has been given to external factors, which effects to venture start-up decision. This study examines the relationship between individual characteristics and entrepreneurship by moderating effect of Hofstede's cultures dimensions theory. For this, 244 copies of the questionnaire were empirically analyzed. According to the results of analysis, internal locus of control, self-efficacy were found to have positive effects on autonomy, innovativeness, pro-activeness. In addition, uncertainty avoidance of Hofstede's cultures dimensions theory were found the moderating effects on entrepreneurship and entrepreneurial intentions. Therefore, this study suggests theoretical and practical implications, as below, according to the results. Firstly, pro-activeness take a important part on venture start-up. Thus, venture start-up institution and venture managers need to develop "venture education curriculum" that fostering the pro-activeness mind of entrepreneur. Secondly, In order to anticipate entrepreneurial intentions more precisely, analyzing the interaction between environmental variables and individual variables is desirable. Lastly, in the future study of entrepreneurship, the comprehensive analysis of correlation between the factors that including three factors of entrepreneurship is need to be conducted and more effective way of readdressing the entrepreneurship is necessary.

DNA chip 또는 microarray는 다수의 유전자 또는 유전자 조각을 (보통 수천내지 수만 개)칩상에 고정시켜 놓고 DNA hybridization 반응을 이용하여 유전자들의 발현 양상을 분석할 수 있는 기술이다. 이러한 high-throughput기술은 예전에는 생각하지 못했던 여러가지 분자생물학의 문제에 대한 해답을 제시해 줄 수 있을 뿐 만 아니라, 분자수준에서의 질병 진단, 신약 개발, 환경 오염 문제의 해결 등 그 응용 가능성이 무한하다. 이 기술의 실용적인 적용을 위해서는 DNA chip을 제작하기 위한 하드웨어/웻웨어 기술 외에도 이러한 데이터로부터 최대한 유용하고 새로운 지식을 창출하기 위한 bioinformatics 기술이 핵심이라고 할 수 있다. 유전자 발현 패턴을 데이터마이닝하는 문제는 크게 clustering, classification, dependency analysis로 구분할 수 있으며 이러한 기술은 통계학과인공지능 기계학습에 기반을 두고 있다. 주로 사용된 기법으로는 principal component analysis, hierarchical clustering, k-means, self-organizing maps, decision trees, multilayer perceptron neural networks, association rules 등이다. 본 세미나에서는 이러한 기본적인 기계학습 기술 외에 최근에 연구되고 있는 새로운 학습 기술로서 probabilistic graphical model (PGM)을 소개하고 이를 DNA chip 데이터 분석에 응용하는 연구를 살펴본다. PGM은 인공신경망, 그래프 이론, 확률 이론이 결합되어 형성된 기계학습 모델로서 인간 두뇌의 기억과 학습 기작에 기반을 두고 있으며 다른 기계학습 모델과의 큰 차이점 중의 하나는 generative model이라는 것이다. 즉 일단 모델이 만들어지면 이것으로부터 새로운 데이터를 생성할 수 있는 능력이 있어서, 만들어진 모델을 검증하고 이로부터 새로운 사실을 추론해 낼 수 있어 biological data mining 문제에서와 같이 새로운 지식을 발견하는 exploratory analysis에 적합하다. 또한probabilistic graphical model은 기존의 신경망 모델과는 달리 deterministic한의사결정이 아니라 확률에 기반한 soft inference를 하고 학습된 모델로부터 관련된 요인들간의 인과관계(causal relationship) 또는 상호의존관계(dependency)를 분석하기에 적합한 장점이 있다. 군체적인 PGM 모델의 예로서, Bayesian network, nonnegative matrix factorization (NMF), generative topographic mapping (GTM)의 구조와 학습 및 추론알고리즘을소개하고 이를 DNA칩 데이터 분석 평가 대회인 CAMDA-2000과 CAMDA-2001에서 사용된cancer diagnosis 문제와 gene-drug dependency analysis 문제에 적용한 결과를 살펴본다.

In a view of rapidly changing business environment, the success and competing power of organizations depend on committed, highly motivated and satisfied human resources. Empowerment is mainly concerned with establishing and building trust between management and employees, and motivating their participation. Also, behavioral integrity emphasizing on the characteristics of effective leaders has shown as direct action that strengthens positive consequences in organizations. However, research regarding behavioral integrity is very limited. Based on the Self-determination Theory, this paper investigates the effect of empowering leadership on employee's job satisfaction and work engagement. Multi-group analysis based on behavioral integrity is also analyzed. An online survey was conducted and 298 employees' data were collected. Using structural equation modeling, results suggest as follows. First, empowering leadership had a positive effect on individual's job satisfaction mediated by their work engagement. Second, the result of the multi-group analysis showed that the effect of empowering leadership on work engagement is stronger in the group with high behavioral integrity. Contrary to the prediction, the result doesn't support the moderating effect on job satisfaction. These findings contribute to our understanding of empowering leadership process. Based on the results, several theoretical and managerial implications are discussed.
