This study attempted to investigate how the effectiveness of value-oriented promotion for media contents depends on self-construal and incorporated Schwartz' value system theory(1992) and Gutman's means-end chain theory(1982) into the development of hypotheses. It was expected that media content promotion emphasizing "openness to change" value would be more appealing to those with independent self-construal, whereas media content promotion emphasizing "conservation" value would be more appealing to those with interdependent self-construal. These hypotheses were generally supported in a series of experiments. Also, the dynamic relationship among the four primary value dimensions proposed by Schwartz (i.e., openness to change, conservation, self-enhancement, self-transcendence) was clearly validated in this study.

This study examined the effects of self-critical perfectionism on organizational citizenship behavior (OCB) and the moderating effects of gender in the relationship to understand deeply the dilemmatic situation resulting from OCB at the individual level. In other words, based on the conservation of resources theory, this study examined how self-critical perfectionism influences the OCB and how gender moderates the relationship between self-critical perfectionism and OCB. More specifically, this study predicts that self-perfectionism will be negatively related to OCB. Furthermore, this negative relationship between self-critical perfectionism and OCB will be strengthened in men compared to women. To test these hypotheses, the supervisor-subordinate survey was conducted, and 150 dyad data were analyzed. The analytical results of HLM (Hierarchical Linear Modeling) showed that self-critical perfectionism negatively influenced the OCB, and this negative effect was strengthened in men compared to women. This paper suggests implications and limitations for the literature on OCB.

본 연구는 가족의 구매의사결정에 대한 실증조사로서 성별역할관념론 및 자원이론과 가족구성원의 지각된 영향 간의 관계를 규명하였다. 영향을 주는 구성원은 남편과 아내와 자녀로 한정했으며, 영향을 지각하는 가족구성원은 남편과 아내로 제한하였다. 성별역할관념변수는 Scanzoni Sex-Role Scale(SSRS)로 측정하였으며, 자원변수는 남편과 아내 각자의 수입과 교육수준으로 측정하였다. SSRS 는 요인분석을 사용하여 차원(요인)을 파악한 후 자원변수와 함께 지각된 영향 간의 관계를 규명하기 위하여 다변량 회귀분석을 사용하였다. 요인분석 결과는 Scanzoni(1975)의 분석 결과와 요인구조 면에서 차이가 있었다. SSRS 는 아내의 척도 2 개 차원과 남편의 척도 3 개 차원으로 구성되어 있다. 그러나 본 연구에서 남편의 척도는 1 개의 차원으로 나타났다. 조사대상이 된 제품은 TV, 냉장고, 세탁기, 침대, 장롱, 식탁, 자동차, 남성정장, 여성정장, 여행지로 모두 10 개 였다. 성별역할관념변수의 영향을 분석한 결과는 "제품 특이적"이거나, 영향을 지각하는 "지각주체 특이적"이거나, 성별역할관념의 "차원 특이적" 현상을 보였다. 또한 우리나라의 남편들은 성별역할관념변수에 상관없이 자기의 영향을 더욱더 크게 지각하는 반면, 아내의 영향을 더욱더 적게 지각하는 경향이 있었다. 아내들도 남편보다는 자기의 영향을 더욱더 크게 지각하는 경향이 있으나 남편만큼 강한 것은 아니었다. 이 결과를 분석하면 남편들은 남성우월의 전통을 유지하려는 경향이 높은 반면 아내들은 이런 전통에 변화를 기대하는 진보적 성향을 띠고 있는 것으로 해석된다. 본 연구의 결과 자원이론은 지지를 받지 못하는 것으로 나타났다. 다시 말해 자원이론은 부부사이에서 기대했던 영향과 반대 방향으로 나타났을 뿐만 아니라 부모와 자식 간에도 기대했던 것과 반대 방향으로 나타났다.

In the process of designing pareto optimal insurance contract, it is necessary to assume that insurance contract conditions are endogenous to build a model. The expected utility, the non-expected utility and the state-dependent utility function can be applied as a insurance decision making principle. The insurance costs may have the linear, convex, and concave ralationship with the indemnity schedule. However, the sunk cost and fixed cost must be recognized. The deductible which decides whether an insurance contract to be a full or partial insurance contract can exist in the forms of straight deductible or diminishing deductible. Indeciding the level of deductible, the types of the insurance and the risks to be insured should be the deciding factors. Especially for recall insurance, there is relatively high chance that the recalling company being bankrupt. Therefore, the possibility of bankrupcy should be the considering factor in deciding the policy limit. The existence of the incomplete market and uninsurable background risk should be understood as restricting conditions of the pareto-optimal insurance contract.

This study analyzed Korean students' affective characteristics in mathematical learning according to school and sex by Factor Analysis and Cognitive Diagnosis Theory. In numerical affective achievements by Factor Analysis, there are mean differences between schools, i.e. elementary school and secondary school. And there are sexual differences within schools and boys show more positive achievement than girls. By Cognitive Diagnosis Theory, I investigated 6 affective attributes' proportions that students achieved according to school and sex. Middle school students' proportion is highest in self-control and anxiety and the attribute that students achieved most in all school is cognizing mathematical value. Boys show higher proportion in self directivity, interest and confidence than girls, but girls show higher proportion in anxiety than boys. In personal profiles, the proportion of students who achieved 5 attributes except anxiety is highest.

전문가 시스템 개발과정에서 완전한 경험적 규칙들을 얻는 것은 극히 어려운 작업이다. 전문가들이 확고한 경험적 규칙들을 얻기위해서는 오랜 시간이 걸리며, 그 얻어진 지식조차 확신할 수 없다. 또한 같은 분야 지식도 전문가들 사이에서 큰 차이를 보일 수 있다. 이러한 상황에서 전문가 시스템이 보다 완전한 지식베이스를 얻어, 주어진 영역에서 기존의 고도 전문가 수준의 전문성을 갖는 완전한 전문가로 활약하기 위해서는 지식 배제, 둘째 기존의 경험적 탐색 공간은 물론 보다 다양한 문제 해결 전략이 가능한 심층적 탐색공간을 제공하여 그로부터 새로운 문제 해결 지식을 학습하는 자기 학습기능이 필요하다. 본지에서는 이러한 자기학습 기능을 갖는 전문가 시스템의 알고리즘을 검토하였다. 그리고 끝으로 전력계통에 대한 적용예로서 전압제어 전문가 시스템을 설명하였다. 아직 전문가 시스템의 자기학습 기능의 구현은 초보적 연구에 머물고 있으며, 그들의 학습 능력조차 낮은 수준에 불과하다. 그러나 전문가 시스템 연구자들은 기존 전문가 시스템의 문제점과 그 적응능력의 중요성을 인식하고 있기 때문에 보다 진보된 개념(데이타들로부터 이론과 원리를 학습하는)이 도입된 자기학습 전문가 시스템의 적용연구는 앞으로 여러분야에서 폭넓게 이루어 질 것으로 기대된다.

In der Kritik der reinen Vernunft entfaltet sich die Lehre des $Selbstbewu{\ss}tseins$, die in sich die verschiedene Auffassungen ${\ddot{u}}ber$ das transzendentale Ich $enth{\ddot{a}}lt$. $Demgem{\ddot{a}}{\ss}$ ist das transzendentale Ich einerseits das Ich als reine $Selbstt{\ddot{a}}tigkeit$. Die Vorstellung des Ich $dr{\ddot{u}}ckt$ insofern als die intellektuelle Vorstellung ${\ddot{u}}ber$ die spontane Handlung des denkenden Ich die numerische Einheit oder die Einfachheit der verschiedenen Handlungen desselben aus. Aber andererseits ist das transzendentale Ich im $Selbstbewu{\ss}tsein$ das Ich als den Gegenstand ${\ddot{u}}berhaupt$. Das Ich als Gegenstand ${\ddot{u}}berhaupt$ ist gerade das Ich als Gegenstand des inneren Sinnes oder das empirische Ich ${\ddot{u}}berhaupt$. In diesem Sinne $dr{\ddot{u}}ckt$ das $Selbstbewu{\ss}tsein$ die unbestimmte Wahrnehmung ${\ddot{u}}berhaupt$, oder apprehensio simplex aus. Auf diese Weise $enth{\ddot{a}}lt$ das transzendentale Ich im Selbstbewusstsein in sich die doppelseitigen Momente. Das Ich im $Selbstbewu{\ss}tsein$ ist einerseits das Ich als das denkende Subjekt, $n{\ddot{a}}mlich$ das logische Ich, aber andererseits zugleich das Ich als das wharnehmende Subjekt, das psychologische Ich ${\ddot{u}}berhaupt$. Und diese doppelseitigen Momente des Ichs unterscheiden sich voneinander, aber zugleich auch $dr{\ddot{u}}cken$ in sich ein und dasselbe Ich aus. Dennoch ist das Problem der Einheit und Entzweiung des Ich im Selbstbewusstsein bleibt in der Kritik der reinen Vernunft als ein $unerkl{\ddot{a}}rbares$, $unaufl{\ddot{o}}sbares$ $R{\ddot{a}}tzel$. Eben mit diesem Problem setzt Kant sich im Opus potumum ernsthaft auseinander und $l{\ddot{o}}st$ dieses Problem durch eine neue Lehre des $Selbstbewu{\ss}tseins$ oder die Lehre der Selbstsezung auf.

The purpose of this study was to investigate the level of self-regulated learning ability for engineering students. Self-regulated learning theory has been studied as the theoretical background and assessment framework explaining life-long ability. A survey was conducted to engineering students from an engineering-centered university, located in Seoul. The research findings were as follows. First, each mean of cognitive regulation, motivation regulation, and behavior regulation was 3.041, 3.051, and 2.996 respectively, indicating that the scores were not high. Second, there was no significant difference in the mean score of self-regulated learning ability between female and male students. Third, students in ABEEK accredited program scored meaningfully higher than students in non-accredited program on only 3 sub-components of organization strategy, metacognition, and task value. Fourth, senior students scored meaningfully higher than 1st year students on only 3 sub-components of metacognition, intrinsic motivation, learning environment management. The results revealed that instructional interventions should be provided for engineering students to develop self-regulated learning ability.

In the advanced information age, learning is an activity in which learners access information resources through computers and Internet to acquire and evaluate information on their own. The emergence of an online learning platform based on the fourth industrial revolution technology is developing into an environment in which elementary and secondary learners learn and study based on constructivism learning theory. In the online learning environment, the researches on the information retrieval ability of the elementary and secondary learners and the self-directed learning ability were found to be highly related. However, it is necessary to analyze the relation between information retrieval ability and self-directed learning ability through a cross-sectional study that is limited to specific curriculum and contents and expands the longitudinal research. In this study, the panel data of the Seoul Education Longitudinal Study collected over 8 years are used to find the difference in self-directed learning ability according to the longitudinal pattern of information retrieval ability and frequency.
