This paper deals with researching and designing the fastening parts to be used in order to assemble various Teaching Aids Robots (or Hands-on Robots) with originally incompatible parts supplied by different manufacturers. The suggested fastening parts provide the compatibility among Teaching Aids Robots even though the educational robot customers use incompatible parts from different companies. The designed fastening parts are classified into four set groups such as frame set, sliding-bar set, connector set, and set of chuck and rivet/bolt. Each set of the fastening parts reflects the needs collected from the users, and then some portion of new idea has been added to implement the needs. In this paper, the examples of the Teaching Aids Robots which are assembled with both commercial parts and the designed parts are presented in order to evaluate the compatibility and usability of the suggested fastening parts. As a result, both compatibility and usability of the fastening parts suggested in this paper were proved. The designed fastening parts have been distributed to more than 100 elementary schools nationwide.

The purpose of this study is to investigate the effect of real-time remote video instruction using zoom on learners' English reading achievement. The study also sought to identify the efficiency of zoom video lectures and consider supplementing them by surveying learners' opinions and satisfaction regarding zoom video lectures. To this end, control and experimental groups were set up, and two achievement tests and a questionnaire were conducted. The study's results demonstrated that zoom video lectures have a positive effect on learners' English reading achievement. The questionnaire found that learners are satisfied with zoom video lectures for the following reasons: 'increased interest in and motivation towards learning', 'self-directed learning', 'active interaction', 'ease of access', 'ease of information retrieval'. At the same time, the questionnaire also found that some learners are dissatisfied with zoom video lectures due to 'mechanical errors or defects', 'poor audio quality', and 'the need to add customized functions for efficient classes'. In practice, zoom video lectures must be supplemented with automatic attendance processing, convenient data upload and download, and more efficient video screen management. Given the recent increase in online classes, we, as instructors, must develop teaching activities and/or strategies for video lectures that can encourage active participation by learners.

The purpose of this study was to investigate the relationship between the psychological/physical home environment, and children's moral judgement and moral behaviors. The subjects for this study were a normal group of 58 children and a delinquent group of 54 children. The normal children were selected from elementary and middle schools in Taegu city, and the delinquent children were from two juvenile prisons in the Taegu area. Children's moral judgement scores were measured by levels of moral judgement as conceptualized by Kohlberg. The major findings of this study were that: 1) There were significant differences between the normal and delinquent groups on democratic conduct, permissive attitude, degree of intimacy between parent and child, and materialism orientation. 2) There were significant differences between the normal and delinquent group on life or death of real parent, living with parents, separation, bereavement or divorce, mother's age, father's educational level, and father's occupational level. 3) There were significant differences between the normal and delinquent group on children's moral judgement scales. 4) Father's educational level was the best index for predicting psychological and physical home environment variables and differences between normal and delinquent children on level of moral judgement.

Purpose: Most research on risky drinking among adults in Korea has focused on problem drinking and high-risk drinking. This paper examines the nature of heavy episodic drinking_(HED) among adults and seeks to identify the risk factors for HED by analyzing differences by gender and age. Method: Participants were 3,886 adults aged 19-64 years from the database of the fifth Korean National Health and Nutritional Examination Survey (KNHANES-V, 2010). Data were analyzed by conducting the Rao_Scott chi-square test, an ANCOVA, and logistic analysis with SAS 9.2. Results: Individuals between 19 and 29 years of age had the highest HED among all age groups. Individuals between 40 and 49 (male adults) and those between 30 and 39 (female adults) showed HED associated with stress, suicidal ideation, smoking, and other health behavior-related variables. Risk factors that affected HED in male adults were age, educational status, and current smoking, while for female adults, the factors were age, educational status, employment, marital status, and current smoking. Conclusions: It is necessary to develop appropriate intervention programs that abate negative emotions and lessen the risk of HED in adults with consideration to gender and age differences.

This study compared parental satisfaction between mothers who have young children with and without disabilities. The study subjects were 100 mothers who take care of disabled children and 123 mothers who take care of non-disabled children. The children's ages were from 3 to 6 years. The results of this study were as follows First, the mothers who take care of disabled children had lower mother's parental satisfaction than those who have ordinary mothers. Second, the children's age and the degree of disability had an affirmative influence on the parental satisfaction of the mothers who have disabled children. There were significant differences in the parental satisfaction of the mothers who have ordinary children according to mothers' age and their educational background. The parental satisfaction in both mother groups increased with increasing parenting efficacy, marital satisfaction and family support, and with decreasing parenting stress. Finally, parenting efficacy, children's age, parenting stress, and family support significantly predicted the parental satisfaction of the mothers who have disabled children while parenting efficacy, parenting stress, and educational background significantly predicted the parental satisfaction of the mothers who have ordinary children.

School uniforms are mass produced by large companies and prominent fashion designers. However many high school students modify their uniform or use fashion accessaries to pursue their individualities and their unique style. The objectives of this research were to identify uniform modification and fashion accessory wearing according to the attitudes toward uniform of high school students. The results were as follows; 1. Factors of the attitudes toward school uniform were style and brand, fashion, role intimation, individuality, and neatness. High school students were classified as the uniform indifference group, the pro-uniform group, and the centrist-uniform group according to their attitudes toward uniform. 2. Many students in academic or boys' high schools were classified into the centrist-uniform stoup, and many in art & physical educational or coeducational high schools were classified into the pro-uniform group. The pro-uniform group modified uniform more and stated that the regulation on the fashion accessory wearing was very strict. The uniform indifference group modified uniform less than other groups and complained less about regulation of fashion accessary wearing. 3. Students in art & physical educational high schools showed more positive tendency toward uniform attitudes, uniform modification, and fashion accessary regulation compliances.
