The purpose of this study was to explore the relationships of mother's childrearing behavior, children's behavior problems, locus of control and peer victimization. The subjects were 360 children of 4th and 6th grade and their mothers. The instruments were Peer Victimization Scale, CBCL, Locus of Control Scale for Children, Childrearing Behavior Scale. The major findings of this study were as follows; (1) The type of peer victimization had a significant difference between girls and boys. That is, boys were more focused on overt victimization than girls. There was no significant gender difference in relational victimization, And there was no significant grade difference in overt and relational victimization. (2) Mother's rejection-restriction childrearing behavior, children's social withdrawal behavior problems, extemal locus of control predicted children's peer victimization. 24% of the variance of children's peer victimization was explained by these variables. (3) Mother's rejection-restriction childrearing behavior was the first contribution factor and had a direct and indirect effect through children's locus of control on children's peer victimization. And children's social withdrawal behavior problems was second contribution factor and had a direct effect on children's peer victimization. Children's locus of control had a direct and indirect effect through children's social withdrawal behavior problems on children's peer victimization. Mother's warmth-acceptance and permissiveness-nonintervention childrearing behavior had indirect effect through children's locus of control on children's peer victimization.

In general, grinding is one of the final machining processes which determines the surface quality of machined products. Since the ground surface is affected by the states of grains and voids on the grinding wheel surface, the wheel should be dressed before the machined surface deteriorates over a quality limit This paper describes a systematic approach to decide a proper dressing chance and an optimal dressing depth for the working grinding wheel. An eddy current sensor and a laser displacement sensor are used to measure the loading on the working wheel surface and the topography of the dressed wheel surface respec- tively. The dressing chance can be properly decided through the relational locus between the amount of handing and the machined surface roughness. An optimal dressing depth to guarantee the less wheel loss and the higher wheel surface quality is decided through the analysis of the variance of topography for the dressed wheel surface, which decreases at three different rates according to the accumulated dressing depth.

This study investigated the relationships among personal characteristics(sex, self-concepts, depression, fear, internal locus of control), home environment(physical and psychological environment, parenting style, attachment to mother), school environment(teacher support, peer victimization), and Korean-Chinese children's aggression in Yanji, China. Two hundred and two(90 boys and 112 girls) 6th graders rated themselves on a questionnaire. Correlation analysis, and multiple regression were conducted using SPSS Window vers. 12. Alienation to mother, and overt and relational victimization by peers were positively related, and communication with mother was negatively related to children's proactive aggression. Alienation to mother, and overt victimization by peers were positively related, and communication with mother, support by teacher were negatively related to children's reactive aggression. Alienation to mother, and overt and relational victimization by peers were positively related, and communication with mother and support by teacher were negatively related to children's relational aggression. The factor with the greatest contribution to explaining the aggression of Korean-Chinese in Yanbin was the alienation to mother.

본 연구에서는 숫돌면의 직접관찰에 의해 적정한 드레싱 시기를 결정하는 것에 관한 연구를 수행했다. 이를 위해, 와전류센서를 숫돌주위에 설치하여 숫돌면의 눈막힘량을 비접촉식으로 직접 측정하므로서 숫돌의 상태를 검출했다. 숫돌의 재생작용에 의한 정상연삭과 눈막힘에 의한 이상연삭의 구분은 검출된 눈막힘량과 가공면 표면거칠기의 상관괘적(Relational Locus)을 통해 드레싱 시기를 결정했다. 또한 이때의 숫돌면의 상태를 레이져 변위센서를 이용해 측정하고 3차원 Topography로 표현했다. 본 논문에서는 이러한 내용들에 대한 실험적 결과들을 소개한다.

본 연구에서는 자원지향 노래심리치료를 통해 위기청소년이 경험하는 심리적 자원을 알아보고자 자원지향 노래심리치료를 구성하여, 조건부 기소유예 및 보호관찰 처분을 받은 청소년 25명을 대상으로 총 8회기 프로그램을 실행하였다. 연구자는 프로그램 종결 후 10명의 참여자를 대상으로 심층 인터뷰를 진행하여 자원 형성에 대한 질적 자료를 수집하였으며, 질적 내용분석 방법을 통해 분석하였다. 연구결과 자원지향 노래심리치료에서 참여자가 경험한 심리적 자원은 총 128개의 개념으로 나타났고, 9개의 심리적 자원 유형이 도출되었다. 9개의 심리적 자원은 '소망/원함', '도전', '인내', '성취감', '유능감', '자부심', '참자기와의 만남', '용기', '내적평가소재'로 나타났다. 이러한 연구결과는 자원지향 노래심리치료 과정을 통해 위기청소년이 경험한 다양한 심리적 자원을 규명하였다는 데 의의가 있다. 추후 연구에서는 자원지향 노래심리치료를 통해 경험하는 참여자의 심리적 변화 과정 및 치료적 역동을 심도있게 탐색할 것을 제안하였다.
