By examining Corporate Social Responsibility (CSR) activities and investigating its current conditions of Japanese companies, which have relatively high reliability in global market and similar oriental ways of thinking in aspect of corporate culture, the study tries to suggest the direction of Korean companies' CSR. As result, the study found that Japanese companies actively participate in the array of actions of giving information about their CSR activities and collecting others opinions to promote their company and brand images. Therefore, this research suggests the following CSR implications: First, companies need to establish a responsible department and responsible system for CSR. Second, they need to reorganize business ethics. Third, companies must provide information about their CSR activities and improve the CSR awareness. Lastly, they need to make strong efforts to communicate with consumers and take actions to consumer correspondence actively.

In this paper a web-based real-time education system, which is able to support education through multimedia, is suggested for the expansion of learner's creative ability in the school. This system is designed so that it can support three things: 1) a real time interaction between instructors and learners, 2) individual learning through such an interaction, and 3) a coercive distribution of display by instructions for preventing the deviation of learners from learning. Also, this system, which UML is applied to, makes efficient interaction possible through the module for the real-time exchange and management of messages even in the multi-user environment. Through this system, not only the simulation by learners can be made for experiments and practices, but also Questions and respondence can be supported on the procedure of experiments and the analysis of their results. This system is built on constructivism, and aimed at helping the learning progress and knowledge formation of learners.

One of the key success factors for Computer Supported Collaborative Learning(CSCL) environments relies on collaborative reflection. Reflection refers to the active, intellectual thinking for monitoring one's own learning process and continuous internal activities of exploring oneself for new learning experiences. Also, reflective activities are closely related not only with the individual aspect of internal exploration but also with the social aspect of learner-learner interaction. This paper suggests four essential macro-level design strategies such as (1)facilitating collaborative awareness, (2)making thinking visualization, (3)negotiation-mediated knowledge construction, (4)providing metacognitive awareness cues or Questions for scaffolding collaborative reflection in the CSCL environments and made some implications for key functional features for the design and development of system components for CSCL.

In MMORPG (Massively Multiplayer Online Role-Playing Game), users advance their own characters to get to the maximum (max) level by performing given tasks in the game scenario. Although it is crucial to retain users with high levels for running online games successfully, little efforts have been paid to investigate them. In this study, by analyzing approximately 60 million in-game logs of over 50,000 users, we aimed to investigate the process through which users achieve the max level and churn of such users since the moment of achieving the max level, and determine possible indicators related to churn after the max level. Based on the result, we can predict churn of the max level users by employing behavioral patterns before the max level. Moreover, we found users who are socially active and communicate with many people before the max level are less likely to leave the service (p<0.05). This study supports that communication patterns are important factors for persistent usage of the users who achieve the max level, which has practical implications to guide elite users on enjoying online games in the long run.

Objectives : There is a need to develop a data quality management algorithm to improve the quality of healthcare data using a data quality management system. In this study, we developed a data quality control algorithms associated with diseases related to hypertension in patients with diabetes mellitus. Methods : To make a data quality algorithm, we extracted the 2011 and 2012 discharge damage survey data from diabetes mellitus patients. Derived variables were created using the primary diagnosis, diagnostic unit, primary surgery and treatment, minor surgery and treatment items. Results : Significant factors in diabetes mellitus patients with hypertension were sex, age, ischemic heart disease, and diagnostic ultrasound of the heart. Depending on the decision tree results, we found four groups with extreme values for diabetes accompanying hypertension patients. Conclusions : There is a need to check the actual data contained in the Outlier (extreme value) groups to improve the quality of the data.

전국에 1,000여개의 다문화 기관들이 활동 중이다. 그중 정부주도형인 여성가족부 지정 다문화가족지원센터 210여 곳을 제외한 나머지 기관들은 대부분 정부 민간 혼합형이거나 민간주도형 기관들이다. 정부주도형 기관들은 중앙정부와 지방자치단체로부터 운영비가 지원되지만 정부 민간 혼합형이나 민간주도형 기관들은 운영비를 기부금 또는 후원금에 의존한다. 그러나 경제위기의 도래로 기부금이나 후원금이 급감하는 상황에서 정부 민간 혼합형이나 민간주도형 기관들의 자립은 더욱더 어려워질 전망이다. 이러한 전망과는 달리, 지원 대상들과 다문화이슈는 지금보다 훨씬 더 늘어날 전망이다. 국내 이주민의 수는 매년 증가추세이다. 향후 2050년이 되면 전체인구의 10%가 외국인이라는 전망도 나온다. 외국인의 정주화 그리고 가족이민 증가에 따른 상이한 종교와 문화에 대한 편견 없는 이해와 대화가 강조될 것이며, 학교교육정책, 직업양성, 노동시장정책, 동등한 노동조건과 사회보장 요구, 사회적 차별에 대한 계몽정책 등 다양한 다문화 이슈도 부각될 것이다. 이처럼 다양한 분야에서 다문화 이슈를 가장 잘 다룰 수 있는 민간주도형 다문화기관의 자립 여부는 다문화 지원정책의 성패와도 연결된다고 볼 수 있다. 결국 민간주도형 다문화기관이 지금의 운영구조를 개선하고 재정적 자립을 확보하기 위해서는 다문화 관련 비즈니스모델 개발을 통해 다문화 기관들이 스스로 자립할 수 있는 사회적기업에 관심을 가질 수밖에 없다. 사천다문화통합지원센터는 비영리민간단체로 지난 13년 동안 창조적인 다문화 사업들을 추진하여 괄목할만한 성과를 거두었다. 그러나 일반 기부금이나 후원금으로 운영비를 충당하고 있는 상황에서 자립 기반 구축을 위한 비즈니스 모델 개발은 필수적이었다. 마침내 요리조리아시아 협동조합을 만들어 청소년 공정여행 프로그램인 세계로여행학교와 아열대채소 농장을 운영중에 있다. 뿐만 아니라 기업의 CSR(Corporate Social Responsibility) 해외공헌사업도 위탁받아 운영하고 있다. 본 연구에서는 사천다문화통합지원센터가 그동안 진행해 온 청소년 공정여행과 아열대채소 농장을 다문화기관의 비즈니스 모델적 측면에서 사례 분석한 후, 벤치마킹을 통해 민간주도형 다문화기관들로 확대시킴으로써 사회혁신의 기회를 증대시킬 방안을 제시하였다.

This study tries to figure out the precarious communication types between parents and their children. For this, the linguistic behavioral characteristics of the main characters in the movie "Daughter" were extracted from their dialogues with the matrix analysis and were conceptualized. These conceptual features were analyzed in the convergence way combined with Transactional analysis and Satir's communication theory. The result shows that the dysfunctional communication between parents and children deteriorates their relation and even could collapse it. Thus. for their whole relation, it is important that they keep the functional communication between them. The study suggested the need for the parental education and youth personality education which let them know how to facilitate their communication.

Leading educational paradigm based on Constructivism drives for many changes in the field of education. It causes the shift from instructor-based to learner-based learning, and cooperative teaming amongst the learners. Multi User Game (MUG) which is a network-based cooperative game is popular among many college students. MUG is known to provide positive and creative activities encouraging learners to participate, reform and produce new knowledge and skills. Thus, it has potential as an effective learning tool. In this study, however, we have designed a prototype of Cooperative MUG Game for elementary students to learn within networked environment to play while learning new knowledge and skills. The elementary students will interact with the other students through chatting while playing MUG.

We use humorous expression in general dialogue. And this humor os especially good methods for expressing more creative and persuasive thoughts. If could not effective data for developing expression techniques, because most of the studies on humor focused on advertising, especially effectiveness for product purchase until now. So, we need the data objectively tested and we can use the data for persuasive, agreeable and effective communication. This study presents new expression methods with humor, classifies the expression type with humor and analyses the specific characters each type. It was as follows. first, which expression types are existing in typography with humor, and how to apply to typography. Second, how to change the propensity to perceive through the communication method and through types of humor Third, what is more effective between typogratphy with humor and typography without humor Miore study based on this must be followed in order to plan objective and agreeable design and improve communication effects.
