To evaluate the educational programs at Science Education Center for the Gifted (SECG) on how it had influenced its graduates, we have surveyed the graduates with questionnaires categorized into four sections: scientific motivation, self-confidence, knowledge/inquiry activities, and peer-to-peer interactions. Of the graduates who studied at SECG for more than two years and are currently attending college, we questioned 26 students and interviewed 10 students. According to our research data, most students evaluated highly the quality of education they received at SECG; especially, in the areas of science knowledge/inquiry activities and social interactions with their peers. Based on the results from the interviews, for these gifted students with highly developed aptitude in science, we concluded that interactions with real-world scientists, investigative approach to and application of newly-learned scientific concepts, and emphasis on interactive activities with other gifted students at SECG were regarded as effective in promoting motivations towards science and self-confidence.

The purpose of the study was to investigate the hedonistic motives experienced by consumers in the apparel buying process. We carried out in-depth interviews by 32 women living in Pusan and to examine the hedonistic motives related to the apparel buying process. It was conducted and analysed by the Spradley's developmental research method.The results showed that the hedonistic motives in apparel buying process, consisted of four components at least, such as Symbolism, Conformity, Distinction, and Impulsiveness. Symbolism represented the social-psychological aspects related to the apparel buying process, such as occupation, role, and self-image etc. Conformity in the apparel buying process was usually influenced by mass-media, and companions. Consumers had strong needs of distintion for self-actualization and self-esteem in apparel buying process. The impulsiveness in apparel buying process were related to the antecedent moods, affection, tastes, price, display, and sales person or accompanied friends. We found that the hedonistic motives in the apparel buying process connected with the emotional responses and were played an important role on the consumer satisfaction in the apparel buying process. They provide informations about hedonistic motives of apparels to consumer behavior researchers and retailers related to apparel products.

Chaos is one of the most significant topics in nonlinear science, and has been intensively studied since the Lorenz system was introduced. One characteristic of a chaotic system is that the signals produced by it do not synchronize with any other system. It therefore seems impossible for two chaotic systems to synchronize with each other, but if the two systems exchange information in just the right way, they can synchronize. This paper addresses the problem of synchronization in a modified Lorenz chaotic system based on active control, sliding mode control, and the Lyapunov stability theory. The considered synchronization scheme consists of identical drive and response generalized systems coupled with linear state error variables. For this, a brief overview of the modified Lorenz chaotic system is given. Then, control rules are derived for chaos synchronization via active control and slide mode control theory, with a strategy for solving the chattering problem. The asymptotic stability of the overall feedback system is established using the Lyapunov stability theory. A set of computer simulation works is presented graphically to confirm the validity of the proposed method.

This research is about influence on academic motivation and satisfaction of college life by Dong-A-Ry activity in students on department of dental hygiene. The results of the study were as follows: 1. The relationship between academic motivation and Dong-A-Ry activity was found to a positive relationship with ${\alpha}$ <0.05 in analysis of variance, which shows that correlation between variables are significantly high. 2. The relationship between satisfaction of college life and Dong-A-Ry activity was found to a positive relationship with ${\alpha}$ < 0.05 in analysis of variance, which shows that correlation between variables are significantly high. 3. This research suggests that students obtain the experience of group activity which is difficult to approach by regular curricular activity. As a result, to improve the highly motivated study and the better satisfaction in college life, Dong-A-Ry activities are needed. And Dong-A-Ry activity can be efficiently facilitated by active participants, efficient program development, facilitator's leadership and so on.

Currently forest interpreter has become one of occupations, and the demand for forest interpretation has been increasing. For that reason, it is important to achieve the goal of forest interpretation and to satisfy its customers. Therefore, this research examined the relationship between organizational commitment and job motivation and analyzed the effects of job motivation on organizational commitment. Firstly, the mean value for interpreters' job motivation was classified into three factors, which were social relationship, affection for forest, and self-development. Secondly, organizational commitment was classified into two factors of goal-oriented and relation-oriented commitments. Thirdly, gender and number of participation made significance differences in job motivation. In addition, organizational commitment of interpreters was different in accordance to their age and affiliated organization. Finally, job motivation had positive impacts on organizational commitment, and especially social relationship influenced positively to general organizational commitment and goal-oriented commitment.

Synchronization is the process of making replicated data on multiple devices be consistent, i.e., identical with each other. In Dec. 2000, major handheld computer manufacturers including Nokia, Ericsson, IBM published the SyncML protocol specification. In this paper, we describe the CNU SyncML server for PIMS(Personal Information Management System) service that we developed based on the SyncML specification. The server architecture and capabilities of the frames are presented along with the procedure of message processing by each frame. We put the CNU SyncML server to the conformance tests and interoperability tests to confirm its functionality. The session managing mechanism of the CNU SyncML server showed better performance than our previous implementations.

This study is a descriptive research study to analyze the relationship between learning motivation, learning immersion, and self-directed learning. For this study, data were collected from August 1 to 30, 2021. The collected data were analyzed using the IBM SPSS/WIN 22.0 program. The learning motivation was positively correlated with learning immersion and self-directed learning. In analysis results, the factors affecting learning immersion are learning motivation and self-directed learning. And it was confirmed that self-direction was a partial mediating factor in the relationship between learning motivation and learning immersion. Learning motivation is an important factor for nursing students' learning immersion and self-directed learning. Therefore, specific measures to improve self-directed learning should be prepared for learning immersion. Therefore, nursing students' self-directed learning is an important factor for learning motivation and learning immersion, and specific measures to improve that should be prepared.
