Although parent-child relationships are fundamental aspects of human development across all societies, this relationship is also shaped in significant ways by culture. Therefore, the present study sought to determine whether adolescent autonomy was predicted in a similar or differential manner by several parent-adolescent variables consisting of parenting behavior, parental authority, and parents' educational attainment in samples of Chinese and American adolescents. The sample for this study included 418 Chinese adolescents and 226 American adolescents. Utilizing structural equation modeling, the results revealed that the effect of paternal authority on adolescent autonomy development is indirect, with the indirect effect being mediated by the authoritative parenting behaviors for both cultural groups. Therefore, the analyses for Chinese and European American youth generated similar association patterns, such that parenting behaviors served as a mediator in the relationship between paternal authority and adolescents' autonomy development. The significance of this present study is to contribute to existing knowledge in the field of adolescent development and to the literature on how parental behaviors and authority in collectivistic societies and individualist societies influence adolescent development.

미국의 한국계 이민가정이 해마다 증가하고 있으나 부모의 문화적응과 자녀양육에 관한 연구는 미흡한 실정이다. 본 연구는 미국 동부지역의 88명의 한인 이민어머니와(M=35.9세 SD=3.77) 2-6세 유아를(M=4.29세 SD=1.06; 49.4% 여아) 대상으로 실시되었다. 어머니의 문화적응 유형에 따라 1) 양육실제에 어떠한 차이가 있는지, 2) 유아의 사회 정서적 행동에는 어떠한 차이가 있는지, 3) 양육실제와 아동의 사회 정서적 행동간에 어떠한 상관이 있는지를 살펴보았다. 연구결과, 한국과 미국문화를 균형지게 통합한 어머니들이 미국문화에서 고립되거나, 두 문화에서 모두 소외된 어머니들보다 자녀에게 더욱 긍정적인(애정표현, 합리적 문제해결, 자율성 격려) 양육실제를 사용하였으며 자녀들 또한 정서적 문제행동은 적은 반면 친사회적 행동은 높은 것으로 나타났다.

로봇이나 가상 캐릭터와 같은 지능형 에이전트가 자율적으로 살아가기 위해서는 주어진 환경을 인식하고, 그에 맞는 최적의 행동을 선택하는 능력을 가지고 있어야 한다. 본 논문은 이러한 지능형 에이전트를 구현하기 위하여, 외부 환경에 적응하면서 최적의 행동을 배우고 선택하는 방법을 연구하였다. 본 논문에서 제안한 방식은 강화 학습을 이용한 행동기반 학습 방법과 기호 학습을 이용한 인지 학습 방법을 통합한 방식으로 다음과 같은 특징을 가진다. 첫째, 외부 환경의 적응성을 수행하기 위하여 강화 학습을 이용하였으며. 이는 지능형 에이전트가 변화하는 환경에 대한 유연성을 가지도록 하였다. 둘째. 경험들에서 귀납적 기계학습과 연관 규칙을 이용하여 규칙을 추출하여 에이전트의 목적에 맞는 환경 요인을 학습함으로 주어진 환경에서 보다 빠르게, 확장된 환경에서 보다 효율적으로 행동을 선택을 하도록 하였다. 제안한 통합방식은 기존의 강화 학습만을 고려한 학습 알고리즘에 비하여 학습 속도를 향상 시킬수 있으며, 기호 학습만을 고려한 학습 알고리즘에 비하여 환경에 유연성을 가지고 행동을 적용할 수 있는 장점을 가진다.

This research focuses on the perceived marketplace influence(PMI: A belief that recognizes the effect that an individual's actions will have on the behavior of other consumers in the market and thus drives them to act on fair trade consumption) of consumers who may act as a more fundamental explanatory alternative to the gap in attitudes and behaviors of fair trade products. The purpose of this study is to investigate the relationship between consumer's self - determination psychological needs (autonomy, competence, relevance), influence (personal influence, market influence), and the assets of fair trade products. As a result of the empirical analysis, it was found that among the major psychological needs related to self-determination, the variables other than competence and the perceived influence relations of consumers can be directly formed, and the perceived consumer effectiveness(PCE) has a positive influence on perceived marketplace influence(PMI). It is also found that the perceived influence of consumers(PCE, PMI) has an influence on the consumers' perceived equity of Fair Trade products. The results of this study will provide an opportunity to theoretically explain the gap between consumers' attitudes and behaviors of Fair Trade products, which is a part of ethical consumption, and provide important implications for the establishment of marketing strategies.

The purpose of this study is to empirically examine the structural relationships among colleague trustworthiness, organizational trust and organizational citizenship behaviors(OCB). To conduct such examination, the author (i) designated colleague trustworthiness, organizational trust and OCB as variables and (ii) designed a research model by conducting preceding studies on the variables. To examine the research model the author collected the survey data from the 2 universities employees, 134 copies of questionnaire. Collected data were analyzed using SPSS and AMOS programs. The analysis results are as follows. Especially, (1) there was no statistically significant relationship between colleague trustworthiness and OCB. (2) it was found that higher degree of integrity the constructs of colleague trustworthiness would lead to higher degree of organizational trust. (3) organizational trust has been found to exert mediating effect on the relationship between colleague trustworthiness and OCB. The implication and limitation which this study are as follows. First, this study has discovered that organizational trust is the important mediating variable that affect the process of relationship between colleague trustworthiness and OCB. This study have limitation in that was conducted based on cross-sectional design of research. Because, the formation of trust is a dynamic process.

컴퓨터와 인간사이의 원활한 의사소통 및 인터랙션을 위해 기존의 키보드, 마우스를 대체할 수 있는 다양한 입력장치들이 개발되고 있다. 하지만 정보를 탐색, 접근하는 데에 있어서 기존의 장치들은 클릭과 같은 제한적인 동작만을 입력 값으로 받아들이므로 이러한 방식에 익숙하지 않은 사용자의 입장에서는 부자연스러움을 느끼는 요인이 된다. 사용자의 제스처를 인식할 수 있는 인터페이스를 통해 일상에서 사물을 사용할 때의 행동양식을 그대로 가져올 수 있다면, 디지털 콘텐츠에 접근하는데 있어 보다 직관적이고 편리하게 컴퓨터와 의사소통 될 수 있다. 제스처는 동작의 자율성이 높고 때로 그 의미를 파악하기 모호하기 때문에 동작들을 정확히 인식하여 구분할 필요가 있다. 본 논문에서는 이를 바탕으로 효과적인 제스처 인터페이스의 구현을 위해 필요한 점들을 살펴보고, 기술적 구현을 통해 디지털 콘텐츠와의 인터랙션을 보여주고자 한다. 정보 접근에 있어 가장 익숙하고 전통적이라 할 수 있는 책의 메타포를 통해 페이지를 넘기는 행동양식을 인식할 수 있는 인터페이스를 개발하고 이를 입력장치로 사용한다. 사용자의 동작을 인식, 파악하여 책을 앞뒤로 넘기거나 탐색하며 원하는 정보에 접근할 수 있도록 유도하고 손 동작을 통한 인터페이스를 수단으로 컴퓨터와의 유연한 의사소통이 가능하도록 구현한다.

Q-학습은 최근에 연구되는 강화학습으로서 환경에 대한 정의가 필요 없어 자율이동로봇의 행동학습에 적합한 방법이다. 그러나 다개체 시스템의 학습처럼 환경이 복잡해짐에 따라 개체의 입출력 변수는 늘어나게 되고 Q함수의 계산량은 기하급수적으로 증가하게 된다. 따라서 이러한 문제를 해결하기 위해 다개체 시스템의 Q-학습에 적합한 연속적인 Q-학습 알고리즘을 제안하였다. 연속적인 Q-학습 알고리즘은 개체가 가질 수 있는 모든 상태-행동 쌍을 하나의 Q함수에 표현하는 방법으로서 계산량 및 복잡성을 줄임으로써 동적으로 변하는 환경에 능동적으로 대처하도록 하였다. 제안한 연속적인 Q-학습 알고리즘을 벽으로 막힌 공간에서 두 포식자와 한 먹이로 구성되는 먹이-포식자 문제에 적용하여 먹이개체의 효율적인 회피능력을 검증하였다.

In this paper addresses the low-level behavior of fuzzy control and the high-level behavior selector for Autonomous Mobile Robots (AMRs) based on a Fuzzy Artificial Immune Network. The sensing information that comes from ultrasonic sensors is the antigen it, and stimulates antibodies. There are many possible combinations of actions between action-patterns and external situations. The question is how to handle the situations to decide the proper action. We propose a fuzzy artificial immune network to solve the above problem. and the computer simulation for an AMR action selector shows the usefulness of the proposed action selector.

The purpose of this study is to explore the relationship between parental attitudes, teachers' autonomy support as perceived by high school students, and the self-directed learning abilities of high school students. A total of 341 high school students from South Korea participated in the study. A survey instrument was used to measure parental attitudes, teacher autonomy support, and students' self-directed learning ability. The results of the study are as follows. First, the rearing attitudes of parents were perceived by the participants as oriented more toward being attainable and relatively less self-directed. There were no significant differences between male and female students, though male students were more likely to perceive their parents' attitudes as more attainable-oriented. The results also show that, in terms of self-directed learning skills among high school students, the more goal-oriented, compassionate, and autonomous the parental attitudes are, the likelier are students to have developed self-directed learning skills. Second, the male students were more aware of the autonomy support of teachers than were the female students. This shows that the results have significant predictive power over the self-directed learning ability among high school students. Accordingly, the perception of autonomy support by teachers affects the development of self-directed learning among students. We can therefore conclude that self-directed learning skills develop most effectively in students who are supported by their teachers.
