본 논문에서는 실시간 동정 환경에 효과적인 L-CAA 에이전트 구조를 제안한다. L-CAA 에이전트 구조는 변화하는 환경에 대한 적응성을 높이기 위해, 선행 연구를 통해 개발된 행위 기반 에이전트 구조인 CAA에 강화 학습 기능을 추가하여 확장한 것이다. 안정적인 성능을 위해 L-CAA에서 행위 선택 메커니즘은 크게 두 단계로 나뉜다. 첫 번째 단계에서는 사용자가 미리 정의한 각 행위의 수행 가능 조건과 효용성을 검사함으로써 행위 라이브러리로부터 실행할 행위들을 추출한다. 하지만 첫 번째 단계에서 다수의 행위가 추출되면, 두 번째 단계에서는 강화 학습의 도움을 받아 이들 중에서 실행할 하나의 행위를 선택한다. 즉, 강화 학습을 통해 갱신된 각 행위들의 Q 함수 값을 서로 비교함으로써, 가장 큰 기대 보상 값을 가진 행위를 선택하여 실행한다. 또한 L-CAA에서는 실행 중인 행위의 유지 가능 조건을 지속적으로 검사하여 환경의 동적 변화로 인해 일부 조건이 만족되지 않는 경우가 발생하면 현재 행위의 실행을 즉시 종료할 수 있다. 그 뿐 아니라, L-CAA는 행위 실행 중에도 효용성이 더 높은 다른 행위가 발생하면 현재의 행위를 일시 정지하였다가 복귀하는 기능도 제공한다. 본 논문에서는 L-CAA 구조의 효과를 분석하기 위해, 대표적인 동적 가상환경인 Unreal Tournament 게임에서 자율적을 동작하는 L-CAA기반의 UTBot 들을 구현하고, 이들을 이용하여 성능실험을 전개해본다.

This study investigated predictors of the behavior related to particulate matter in nursing students. The participants in this descriptive study were 186 nursing students at K university in G city from May 1 to 14 in 2018. Collected data were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple linear regression using SPSS WIN 18.0 program. The level of knowledge(10.6/15), attitude(59.94/75) and behavior(42.56/60) were relatively high. The significant predictors of the behavior were attitude(β=.591, p<.001), smoking(β=-.134, p=.049) and respiratory disease(β=.133, p=.025), and explained 40.1% of it. Educational programs to enhance nursing students' health promoting behaviors against particulate matter must be focused on attitude change.

The purpose of this study is to define determinants of VoIP user acceptance and to verify significant causality among latent variables - performance expectancy, effort expectancy, cost expectancy, social influence, facilitating conditions, behavioral intend, use behavior - based on UTAUT model. We presented the expanded hypotheses including the new factor, cost expectancy and analyzed the moderating effect of user age, gender and usage experience variables. For a accuracy of predicted results, we focused on survey analysis with 641 real user samples. Compared to previous studies, it is meaningful that this research verified the conceptual difference between behavioral intention and usage behavior. As a result, all proposed hypotheses accepted and moderating effects are supported significantly in age and use experience moderating variables.

The purpose of this study was to examine the relationship between college students' health perception, health beliefs, and health promotion behaviors. For data analysis, item analysis, factor analysis, and reliability analysis were conducted. In addition, correlation analysis and path analysis were conducted to understand the relationship between variables. As a result of the analysis, the following conclusions were obtained. As a result of conducting path analysis to verify the causal effect between college students' health perception, health beliefs, and health promotion behaviors, the model was relatively high in various fitness indices, and all path coefficients included in the model were statistically significant. Specifically, there were significant positive relationships in all pathway coefficients, but health perception and perceived disability, perceived disability and health promotion behavior were negatively related. In subsequent studies, it is considered necessary to analyze various variables related to health promotion behavior.

The purpose of this study was to examine the effect of the social support on health promotion behavior and life style of elderly people participation in physical education program. Total of 284, elderly people participated in this study. Data ware analyzed by descriptive statistical analysis, reliability analysis, exploratory factor analysis, correlation analysis, and multiple regression with SPSS 18.0 ver. program. The results were as following. First, social support influenced significantly on their health promotion behaviors. Second, social support influenced significantly on their life style. Third, health promotion behavior influenced significantly on their life style.

This paper aims to analyse the recent changes in social welfare services from a relational perspective. Discourses of the privatization of welfare state, the welfare mix approach, and consumerism have provided frames for interpreting the changes in social services in Korea. The nature of social welfare services, being a "relational goods" requires its focus to be in its relational aspects: the relation between service user and service practitioner; the relation between service user and provider; the relation between service user and government; the relation between service practitioner and provider; the relation between service practitioner and government; and the relation between service provider and government. Analysis of such relations will explore their transformation toward formalness and equality in social welfare services. In conclude, the study reveals a process of modernization, defined as a transition from informal relations to formal contractual relations, based on one's rights, responsibilities and obligations. Previous relations, of paternalistic, arbitrary and hierarchical characteristics, can be seen as being substituted by more formal, institutionalized and equalized relations. In terms of service purchasing contract between service user and service provider and employment contract between service provider and service worker are recognized with the latter characteristics. This relational analysis leads a discussion concerning the creation of institutional basis of one's rights and responsibilities in the fields of social welfare services in Korea.

The purpose of this study was to identify the relationships among school-aged children's perceived parenting style, children's self-esteem, health promoting behavior and to determine whether self-esteem was a the mediator of the relationship between parenting style and health promoting behavior. Participants were 425 school-aged children of 5th and 6th grade. Data were analyzed using t-tests, Pearson correlation, and hierarchical multiple regression. The child's health promoting behavior was positively associated with receptive parenting style and positively associated with self-esteem. Also, the results showed that the effect of receptive parenting style on health promoting behavior was significantly partially mediated by self-esteem. Therefore, parenting style and children's self-esteem need to be factored in when designing and applying health education program for school-aged children. Also, the program need to be designed to enhance receptive parenting style that can lead to children's increase self-esteem.

본 연구에서는 전자상거래에서 소비자 구매행위에 영향을 미치는 요인이 무엇인지에 대하여분석을 하였다. 전자상거래는 거래활동의 주체에 따라 기업내 거래, 기업간거래, 기업과 소비자간거래 등으로 분류할 수 있는데, 기업과 소비자간의 전자상거래가 활성화되기 위해서는 먼저 전자상거래에서 소비자의 구매행위에 미치는 영향요인에 관한 분석이 이루어져야 한다. 따라서 본 연구에서는 기업과 소비자간의 전자상거래 관점에서 소비자들이 전자상거래에서 제품이나 서비스 구매시 영향을 미치는 요인들이 무엇인지 설문조사를 통해 얻어진 자료를 토대로 실증분석을 하여 관련성을 검증하였다

공정거래 위반사건은 다른 위반행위와 같이 단순히 법률 문구의 해석을 통해 위법성 여부를 판단할 수 있는 성격의 것이 아니다. 공정거래사건의 위법성 판단을 위해서는 유기체처럼 살아 움직이는 다양한 시장을 일정하게 정해 놓고 그 시장에 대하여 경쟁보호의 관점에서 종합적이고도 다각적으로 분석할 필요가 있기 때문이다. 즉 공정거래사건은 단순히 행위 그 자체만을 가지고 위법성 여부를 판단하기는 어렵고, 그 행위와 관련된 시장에서의 제품 및 그 원료의 생산$\cdot$유통$\cdot$판매$\cdot$소비, 업종의 특성, 해외수입 등 다양한 변수들을 분석하여 현재의 시장상황은 물론 향후 예상되는 시장상황까지 고려하여 판단할 수 있는 고도의 전문적이고 치밀한 작업이 요구되는 것이다.
