  • 일반적으로 이벤트는 발생 시점이라는 시간 속성을 갖는다. 그리고 고객 단위로 이벤트를 축적한 데이터베이스가 있다면 데이터 마이닝을 통하여 유용한 정보를 탐사할 수 있다. 특히 이벤트 발생의 원인과 결과에 대한 관계 규칙을 찾아낼 수 있다면 과거의 정보를 바탕으로 미래를 예측할 수 있는 예측 판단 정보로 사용할 수 있다. 본 연구에서는 데이터 스트림 시스템에서 시간 관계 규칙을 탐사하고 시간 관계 규칙을 구성하는 이벤트 간의 영향력을 측정하기 위한 SM-EC(data Stream Mining for Exploration of Causality)기법을 제안한다. 실험을 통하여 SM-EC가 제공하는 영향력 정보는 다양한 비상 상황에 대처하는 중요한 척도가 될 수 있음을 확인하였다.

  • 본 연구는 저탄소녹색성장전략의 분석을 통해 이명박 정부 하에서의 국가-시장-사회관계를 분석하고 있다. 전체적으로 이명박 정부의 정치경제발전모델이 자유주의적임을 부정하기는 어렵지만 순수하게 신자유주의적이라고 보기는 어렵다. 부분적으로 중상주의적 요소가 강하게 남아 있다. 아울러 국가와 시장간의 관계는 원칙적으로는 서로 일정거리를 유지하는 객관적인 성격을 가지고 있으나 녹색산업분야에서는 친산업·친기업적 요소가 강하게 존재하고 있다. 국가-사회관계는 갈등적이고 배제적이다. 이러한 관점에서 볼 때 이명 박정부의 민주주의모델은 법적·제도적인 것이고 참여민주주의적 모델과는 거리를 두고 있다. 결국 사회배제적이고 친산업/친기업적 속성을 내포하는 한 시민사회세력의 반발에 직면하여 지속가능하지 못하게 되는 한계에 봉착하게 될 개연성이 높다.

  • Purpose: This study tested a model of hospice volunteer's motivations and outcomes to encourage more volunteer workers to participate in hospice care. Methods: This included 200 volunteers who attended the Autumn Conference in 2007 and 132 volunteers from five hospice organizations. Results: Volunteers' existential well-being affected an endogenous variable of volunteers' participation in volunteer activities. The durability of volunteer activity was affected by value motivation, the level of participation in volunteer activities and the level of job satisfaction. For volunteers' job satisfaction level, valid endogenous variables included existential well-being, social motivation, understanding motivation and value motivation. The durability of volunteer activities was indirectly affected through three different paths. Volunteers' existential well-being determined the level of their participation in volunteer activities, which in turn affected the durability of such activities. Social motivation influenced volunteers' job satisfaction, and then the durability of volunteer activities. Volunteers' understanding of motivation also influenced their job satisfaction, and then the durability of volunteer activities. Conclusion: Based on these results, this study proposes that the durability of volunteers activities could be improved by developing a program to improve volunteers' well-being and by providing volunteers with education on altruistic values, encouraging them to seek intellectual growth, and advocating them to continue volunteer activities based on close relationships with other volunteers.

  • This Research is based on the theory of the prior researches that have demonstrated a positive impact of the entrepreneurship and competitive advantages on business performance. And the purpose of this research which approaches in the viewpoint of combining a entrepreneurial attribute including two factors(entrepreneurship and commercialization capabilities) and the differentiated competitive advantage as a role of core competence is to examine how the combined competence affects the business performance. In order to achieve this purpose, we conduct a survey for CEO of 250 small firms which belong to the start-up phase and are located in the 6 administrative region with the assistance of Small & Medium Business Administration representatives and analyze empirically the survey data by utilizing statistical program(Spss 18.0). As the results, we conclude that the entrepreneurial attributes of small firms' CEO and DFCA have a positive impact on business performance respectively and the entrepreneurship, one of the two entrepreneurial factors, has a positive impact on choosing DFCA. Also we report that DFCA plays a mediating role with regards to relationship between entrepreneurial attributes and business performance. Therefore, this research suggests the followings: First, the CEO of start-up business should focus on building a differential competitive advantage which is the basis for creating competitiveness from the initial point. Secondly, he should make a alignment for core competencies, in order to reach the stable growth phase in the shortest period, through which the entrepreneurial attributes is to be inherent as a discriminatory competitive competence. Third, he should promote to establish a business strategy based on strengthening of entrepreneurship and discriminatory competitive as a growth strategy during start-up phase.

  • The purposes of this study were to analyze the effects of a marine leisure exhibition event(MLEE)'s appraisal attributes on visitors' satisfaction and repurchase behavior and thus provide fundamental information that facilitates developing effective marketing and operational strategies for a MLEE. In order to accomplish such purposes, this study employed a survey with a total of 300 visitors to a MLEE hosted by G Province. Questionnaires were developed on the basis of related studies and modified to reflect the study context. Then, such questionnaires were verified to be valid and reliable through content validity, exploratory factor analysis and internal consistency analysis. Valid 286 questionnaires were analyzed with correlation analysis and multiple regression analysis on significance level of .05. Following findings were derived from current study. First of all, the appraisal attributes of a MLEE had a significant effect on visitors' satisfaction and among them only the factor of event program had a unique relation with the levels of satisfaction. In addition, the appraisal attributes of the MLEE also had a significant effect on visitors' repurchase behavior and among them event program, transportation and employee factors had unique relations with the performance variable in order. In conclusion, all the research hypotheses that had been set up through previous studies were confirmed in this study.

  • This paper is to explore considerations in authority control to accommodate LRM nomen entities through the literature reviews, the analysis of RDA rules, and the opinion survey of domestic catalog experts. As a result, for authority control, considerations were proposed in the aspect of nomen's attribute elements, catalog description, and MARC authority format. First, it is necessary to describe in as much detail as possible the category, the scheme, intended audience, the context of use, the reference source, the language, the script, the script conversion as the attributes of the nomen with the status of identification, note, and indifferentiated name indicators added in RDA. Second, the description method of attribute elements and relational elements of nomen can be unstructured, structured, identifier, and IRI as suggested in RDA, and vocabulary encoding scheme (VES) and string encoding scheme (SES) should be written for structured description, Also, cataloging rules for structuring authorized access points and preferred names/title should be established. Third, an additional expansion plan based on Maxwell's expansion (draft) was proposed in order to prepare the MARC 21 authority format to reflect the LRM nomen. (1) The attribute must be described in 4XX and 5XX so that the attribute can be entered for each nomen, and the attributes of the nomen to be described in 1XX, 5XX and 4XX are presented separately. (2) In order to describe the nomen category, language, script, script conversion, context of use, and date of usage as a nomen attribute, field and subfield in MARC 21 must be added. Accordingly, it was proposed to expand the subfield of 368, 381, and 377, and to add fields to describe the context of use and date of usage. The considerations in authority control for the LRM nomen proposed in this paper will be the basis for establishing an authority control plan that reflects LRM in Korea.

  • This study examines the role of family involvement and national culture in entrepreneurs' choice of mode of entry into entrepreneurship. Mode of entry consists of two choices: starting a new venture or taking over an existing firm. Specifically, we investigate how cultural values moderate the relationship between family involvement and their choice of business takeover. Using a cross-national sample of 3,831 respondents from 33 countries in Flash Eurobarometer data, we develop key variables and test our hypotheses employing hierarchical linear modelling. Our results show that the relationship between family involvement of entrepreneurs and their choice of business takeover is moderated by individualism, short term orientation, and power distance. This research contributes to understanding comparative international entrepreneurship based on national culture. Implications for policy makers and educators are discussed.

  • This study explores a value chain structure of TV program including news, drama, and comedy. The purpose of this research focused on factor analysis and the relationship among viewer's program selection motivations. This research explores correlation between personal value and viewing motivation. This study was to identify the value structure of respondent on TV program(news, drama, comedy) based on means-end chain theory. The research used structured APT laddering questions and 251 data was analysed. Through such analysis, category difference by stage and relationship difference were identified and hierarchical value map was compared. There are four different value ladders: first is attributes, functional consequences, psychological consequences, and final value. The result shows that on news program the basic function is viewers are want to visual factor and quickly acquire social news and they pursue a value of personal social relationship. Whereas, on drama program, the viewers are reflected by around person, and they selected a program based on closed related person. In addition, the viewers are influenced by program's social nomination, production's brand in drama, and performer's nomination, producer and program prominence on comedy. The program selection is highly correlated on program selection's credibility, vital energetic life, and social relationship. The results shows that there was no significant difference between low involvement group and high involvement group for main category involvement group respondents.

  • As one of empirical research and developments on BIM applications to improve design quality and productivity of building, efforts have been devoted to automated compliance checking of building design for building permit. KBimLogic is a mechanism that translate Korean Buidling Act to the computational language called KBimCode. KBimCode aims to standardized and neutral language that can be applied to various design rules. This paper focuses on testing expandability of KBimCode by appling it on Chinese Building Act. We analyzed Chinese national regulation on fire protection and evacuation, based on 1) Object·property, 2) function for predicate processing, 3) relationship of sentences. As a result, Chinese Building Act were successfully translated to KBimCode with some important implications for further application. Based on the finding of the paper, KBimCode is expected to be applicable to kinds of design rules.
