This study was interested in dissatisfaction in the service encounter from the service employee's viewpoint by exploring employee dissatisfaction and the problem customers as the causes. The study explored the incidents leading to dissatisfactory service encounters from the service employee's viewpoint, the causes of the dissatisfactory incidents, and the attitudinal, verbal and behavioral expressions of the customers involved in the incidents. Employees of the beauty service business were individually interviewed, and 204 incidents were analyzed. The incidents were categorized to identify the events and related behaviors of customers that caused employee dissatisfaction. Three major groups were classified: the way dissatisfied customers complain; customers' misbehaviors; and customers' no harmful behaviors. Further the major groups were classified into 8 categories. Based on the findings the study provided implications for employee and customer management.

In this study, we propose a scheduling analysis method of the Flexible management system using the transitive matrix. The Scheduling problem is a combination-optimization problem basically, and a complexity is increased exponentially for a size of the problem. To reduce an increase of a complexity, we define that the basic unit of concurrency (short BUC) is a set of control flows based on behavioral properties in the net. And we propose an algorithm to divide original system into some BUC. To sum up, we divide a petri net model of the Flexible management system Into the basic unit of concurrency through the division algorithm using the transitive matrix. Then we apply it to the division-scheduling algorithm to find an efficient scheduling. Finally, we verify its efficiency with an example.

This research is about how the adapted learning of descriptive assessment problems influence on the extension of the ability of the students. As a result, adapted learning of descriptive assessment problems totally led to positive effect, and according to the analyses of behavioral objectives divided into knowledge, comprehension and problem solving, they had more effect on the ability of students' problem solving. Learning attitude of the students were changed into self-centered learning attitude and interest on the subject of mathematics were highly increased since the research had started. If we adapt this research to the learning of mathematics after we develop various problems that can develop creativity, I'm sure that it will be a effective way for both extension of the ability and problem solving ability of the students.

This case study is performed to check the validity of cognitive behavioral therapy for high school students with mathematics anxiety. In order to find out whether it is effective or not, one female high school student who suffers physically and mentally from mathematics anxiety was selected and cognitive behavioral therapy was applied. The therapy is applied to her for 30 to 40 minutes, once a week, and for eight weeks. The main themes were: To understand my problem, To write down thinking log, To set up a plan for actions, To experiment actions, To change intermediate confidence, To change core belief. To check the validity, before and after the experiment, revised version of Heo(1996)'s assessment tools for mathematics anxiety was applied. The subject was interviewed and the results of the therapy were compared and analyzed. According to the research, the worst mathematics anxiety of the subject was test anxiety. After the procedure, the anxiety related to mathematics and teachers was lessened. Especially, the subject had changed her mind and become more positive and optimistic on solving difficult mathematics problems. Therefore, the effectiveness of cognitive behavioral therapy on mathematics anxiety was confirmed. It is required to construct special program - about cognitive behavioral therapy, interactions of cognitive-affective causes, and group therapy - and check the validity of it.

Researches on children's traffic behavior have only focused on traffic accidents and the number of accidents, and therefore it's been impossible to deal with more broad field of study. In this research we can review the possibility of traffic accidents of children and provide them with traffic education. The goal of this research is to develop a device for measuring possibility of children in terms of traffic behavior. Around 600 elementary students of two schools involved in the pretest with 259 questions and about 3,500 students(junior level 53 questions & senior level 72 questions) involved in practical test. At the result of the research, junior level extracted 4 factors(Lack of behavioral control, Aggressive, Self-regulation, Impulsive Instinct) and 44 questions, and senior level extracted 4 factors(Lack of behavioral control, Depression, Sense-oriented, Aggressive) and 69 questions. We take the gender consideration in separate the groups whether the group has traffic behavioral problem or not. In these series of research, we got the standard score such as junior male student, 63 & female student, 50 and senior male student, 110 & female student, 99.

Purpose: This study was conducted to identify factors affecting mental health and behavioral problems among high school students through the lens of a Social Cognitive Career Theory. Methods: A descriptive study was carried out with 384 high school students in Seoul, Korea. A self-administrative questionnaire was used. It consisted of items on person background variables, career-related variables including career barriers, learning experiences, self-efficacy, outcome expectations, and career indecision, and mental health and behavioral problems. Descriptive statistics, correlation analysis and multiple regression analysis were performed using the SPSS 21.0 program. Results: The results showed that perceived stress (t=5.12, p<.001), perceived health status (t=-4.08, p=.002), and school record (t=5.46, p<.001) were statistically significant variables. Also, career barriers (t=10.57, p<.001) was a significant factor influencing mental health and behavioral problems. Conclusion: These findings indicate that among career-related variables, career barrier needs to be considered for preventive and therapeutic approach to mental health and behavioral problems in adolescents. Furthermore, the results suggest that career-related stress level should be assessed in high school students on a regular basis.

The purpose of this study is to propose how the interior of the child psychiatric therapy Environment should be designed according to different problems that children have. For the purpose, this research has been conducted with a literature review and an empirical survey. The subjects of the survey were 100 children, 58 male and 42 female, who were using child psychiatric therapy centers located in Busan. Findings are as follows: (1) Children with behavior problem($C_b$) showed a significantly higher satistaction with the entrance and the information in a given child psychiatric therapy space than children with emotional problem ($C_e$) did. (2) Spatial attitude of $C_e$ and $C_b$ were significantly differed. (3) Colors that were being preferred by $C_e$ were cold colors, for example, blue and indigo. While, $C_b$ were preferring warm colors such as red and yellow. (4) There was difference in the image of a entrance and classrooms at the child psychiatric therapy center that children had in mind, the two groups of children were quite differently feeling about the size and noise of the therapy space.

The purpose of this study was to examine the nature of psychopathology and psychosocial environments of children with Atopic Dermatitis(AD) and their relationship to skin symptoms. Seventy outpatients with AD(mean age 9.94, range 4-15 years) and their mothers were subjected to psychiatric interview and parent- and self-report questionnaire(CBCL, MBRI, CDI, Spielberger's State-Trait Anxiety Inventory for Children(STAI), Family Impact questionnaire). Disease severity was assessed in three dimensions(skin extent, disease activity, and subjective symptom) by SCORAD index. Sixteen(22.9%) of our sample were suspected to have behavioral-emotional problems and they were different from non-problem group on depression, trait-anxiety, maternal controlling attitude and negative appraisal of children. While skin inflammation activity was correlated with only trait-anxiety and depression, subjective skin symptoms were correlated with many psychosocial factors such as depression, state-and traitanxiety, family-impact, social competence, internalized and externalized behavioral problem, sexual problem, and mother's positive appraisal of children). We concluded that children with AD are highrisk group for behavioral-emotional problems, and these problems along with maternal negative parenting attitude can affect their subjective symptom experience.

The purpose of this study was to analyze the responses and the behavioral characteristics between mathematically promising students and normal students in solving open-ended problems. For this study, 55 mathematically promising students were selected from the Science Education Institute for the Gifted at Seoul National University of Education as well as 100 normal students from three 6th grade classes of a regular elementary school. The students were given 50 minutes to complete a written test consisting of five open-ended problems. A post-test interview was also conducted and added to the results of the written test. The conclusions of this study were summarized as follows: First, analysis and grouping problems are the most suitable in an open-ended problem study to stimulate the creativity of mathematically promising students. Second, open-ended problems are helpful for mathematically promising students' generative learning. The mathematically promising students had a tendency to find a variety of creative methods when solving open-ended problems. Third, mathematically promising students need to improve their ability to make-up new conditions and change the conditions to solve the problems. Fourth, various topics and subjects can be integrated into the classes for mathematically promising students. Fifth, the quality of students' former education and its effect on their ability to solve open-ended problems must be taken into consideration. Finally, a creative thinking class can be introduce to the general class. A number of normal students had creativity score similar to those of the mathematically promising students, suggesting that the introduction of a more challenging mathematics curriculum similar to that of the mathematically promising students into the general curriculum may be needed and possible.
