The purpose of this study is to analyze the variables affecting the institutional commitment of college students. Based on the relevant literature review, this study subdivided institutional commitment of college students into three; academic integration, social integration and institutional commitment. To achieve the goals, the hierarchical regression analysis was conducted using KELS(Korea Educational Longitudinal Survey) data collected by KEDI in 2018. Major findings are as follows: factors related to college experiences such as learning styles, negligence of learning, college climate, interaction with faculty members or peer group were found to be associated with the institutional commitment of college students. With regard to students' background, male students revealed lower level of academic integration and institutional commitment. The regression model disclosed that students from medicine demonstrated higher social integration compared to other majors. Based on the findings of the study, policy implications were discussed.

The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.

Medication is widely accepted as an effective method to reduce the problem of attention deficit, hyperactivity, impulsivity, resistance and violence of ADHD children. However, it does not provide us with the solution on the conflicting routinized behavioral patterns to gain a high level of self-control and acceptable behavior. As a way of replacing medication, this study applies the social skills training program for ADHD children and measures the level of improvement of social skills and the change of the behavioral patterns. The experiment is carried out on 16 children ranged from 6 to 13 years of age for 10 weeks. The patients are divided into three groups：a pure ADHD group, an ADHD group with conduct disorder, an ADHD group with mental retardation and other symptoms. The change of symptoms and the change of social skills are measured by the Child Behavior Checklist(CBCL), the ADD-H Comprehensive Teacher’s Rating Scale(ACTeRS) and the Social Skills Rating Scale(SSRS), and finally Mastson Evaluation of Social Skills for Youth(MESSY). Wilcoxon signed ranks test is used to evaluate the effect of the treatment, and Kruskal-Wallis test is also used to measure the change after the treatment in each of the three groups. In the ADHD group with conduct disorder, the examination of the effect of the treatment shows a significant reduction of violence in the area of behavior(p<.05), and a significant difference of activity and social skills in the area of social competent(p<.001). In the ADHD group with mental retardation and other symptoms, a significant rise of social skills is found in the area of social skills evaluation (p<.05). However, there is no significant difference of effect by the treatment among the three groups. In addition, the current examination shows that the social skills training program does not make a statistically significant contribution to the social skills of the ADHD children. On the other hand, the training helps some children, when it is suitable for the characteristics and accompanying symptoms of the children：it reduces the level of violence in the ADHD group with conduct disorder, and it raises the social skills in the ADHD group with mental retardation. In other words, the social skills training program will reduce the conduct disorder and helps peer relation for ADHD children.

This study was conducted to evaluate the effect of Sikhe made by medicinal herb on the functional level of liver. Water extract I (12.9% W/W) and II (25.8% W/W) were obtained from medicinal materials: Caragana Sinica, Glycyrrhiza uralensis, Atractylodes rhizoma alba, Atractylodes rhizoma alba, Crataegus pinnatifida, Paeonia lactiflora Pasll., Hordeum vulgare Linne, Oryza sativa Linne, ginger, peer and jujube. Experimental groups were divided into the control diet group (C), high fat diet group (HF), high fat diet treated with 5% extract I group (HFE I ) and high fat diet treated with 5% extract II group (HFE II). In sensory evaluation, overall quality scores associated with color, aroma, flavor and taste were significantly higher in water extract II than in water extract 1. After investigating functional and lipid levels of livers in rats, we found that the administration of water extract I or water extract II to the high fat diet group (HF) did not affect the gain of body weight but mildly reduced GOT or GPT activity in the high diet group. Moreover, administration of these medicinal herbal extracts significantly decreased the levels of total lipid, triglyceride and total cholesterol in the high fat diet group (HF). However, administration of these medicinal herbal extracts did not affect the level of phospholipid. In conclusion, as Sikhe made by medicinal herb slightly decreased the activity of GOT or GPT and amount of lipid in liver, prevention against high fat diet is thought to be important for liver protection.

The purpose of this study was to verify the influence of musical activities on social and emotional behavior of infants, through providing musical activities to the infants who were cared in a nursery and observing the interactions between peer group, or a therapist and an infant derived during them. The subject is 24 infants who are under 2 years of age(25~36months) at two nurseries located in Bundang area, and 13 infants among them are randomly assigned as study group and 11 infants as control group. Pretest and posttest about social and emotional behavior are performed, and ITSEA developed by Brggs-Gowan and Carter(2001) and amended by Shin Ji Yeon(2004) was used as an evaluation tool. Infants' changes of interaction behaviors during musical play were also analyzed quantitatively and qualitatively, and for the analysis, infant's social play behavior examination tool developed by Holloway and Reichhart-Erickson(1988) was adopted. Based on time sampling method, each item of this tool was evaluated. Each session was performed for 15 minutes, and 60 times of analysis about interactions per session was conducted at every 15 seconds. The analysis result was showed with a table and a graph, and described qualitatively about behavior changes. When compared social and emotional positive behavior average figures and negative behavior average figures between study group and control group, this study showed that the positive behavior figure of study group was increased and the negative behavior figure was decreased. While concentration and empathy among positive behaviors increased meaningfully, aggression, defiance, separation anxiety and rejection to new things among negative activities also decreased meaningfully. The conclusion of this study is as follows. First, interactions with peers or a therapist based on music and musical experience make an effect on strengthening positive behavior among social and emotional behavior and decreasing negative behavior. Second, music has influence on negative behaviors more than positive behaviors of an infant, and produces a good effect on sub behaviors of negative behaviors specially.

The focus of the research was on identifying the risk factors that may result in unprepared intercourse among the adolescent from an ecological systems prospective. A survey questionnaire was conducted from September through December 1999 to 2326 youths, ages from 13-18 years old. After eliminating thirty respondents from Unwed Mother's Home we found that 8.8% of the remaining respondents had experienced sexual intercourse. Of those, 5% of the female and 13.4% of male adolescents has had sexual intercourse, showing 2.7 times more for the male sample population. Broken down to age groups, 3.2% of the thirteen years old group and 19.2% of the eighteen years old group had experienced intercourse, an almost six fold increase in the older age group. To find out the differences between those who had and not had experienced intercourse the group was then divided into two comparative groups by same sex and age variables. Findings from comparative analysis identified five ecological system risk factors among the youth sample that had intercourse；First, individual factor：adolescents who thought less of themselves or didn't consider their potentials, those more exposed other risk behaviors such as drinking, smoking, drugs, runaway and come in contact with pornography, those who thought they knew more about sex and etc. Second, family factor：those who thought family was less important, had less supportive family, higher or lower income family and etc. Third, peer factor：Both groups thought friends were important and had their support. The group with intercourse experience seems to be think that more peers are experiencing other risk behavior. Fourth, school factor：Those in the group who had experienced intercourse seems to think school is less important and with lower academic achievements. Fifth, community factor：There were no statistical significant differences found between the two groups. The overall results from this study implies that if we want to prevent our youths from having unprepared intercourse during adolescence the significance of having meaningful emerging self, family relationship and school experience is important. This study identified the risk factors leading to adolescent sexual intercourse but further research is necessary in finding out about their predictability.

Pub/sub system enables data users to access any necessary data without knowledge of the data producer and synchronization with the data producer. It is widely used as the middleware technology for the data-centric services. DDS (Data Distribution Service) is a standard middleware supported by the OMG (Object Management Group), one of global standardization organizations. It is considered quite useful as a standard middleware for US military services. However, it is well-known that it takes considerably long time in searching the Participants and Endpoints in the system, especially when the system is booting up. In this paper, we propose a discovery scheme to reduce the latency when the participants and Endpoints are densely distributed in a small area. We propose to modify the standard DDS discovery process in three folds. First, we integrate the Endpoint discovery process with the Participant discovery process. Second, we reduce the number of connections per participant during the discovery process by adopting the concept of successors in Distributed Hashing scheme. Third, instead of UDP, the participants are connected through TCP to exploit the reliable delivery feature of TCP. We evaluated the performance of our scheme by comparing with the standard DDS discovery process. The evaluation results show that our scheme achieves quite lower discovery latency in case that the Participants and the Endpoints are densely distributed in a local network.

This study was undertaken in order to estimate the accuracy of disease code of the Korean National Medical Insurance Data and disease the characteristics related to the accuracy. To accomplish these objectives, 2,431 cases coded as notifiable acute communicable diseases (NACD) were randomly selected from 1994 National Medical Insurance data file and family medicine specialists reviewed the medical records to confirm the diagnostic accuracy and investigate the related factors. Major findings obtained from this study are as follows : 1. The accuracy rate of disease code of NACD in National Medical Insurance data was very low, 10.1% (95% C.I. : 8.8-11.4). 2. The reasons of inaccuracy in disease code were 1) claiming process related administrative error by physician and non-physician personnel in medical institutions (41.0%), 2) input error of claims data by key punchers of National Medical Insurer (31.3%) and 3) diagnostic error by physicians (21.7%). 3. Characteristics significantly related with lowering the accuracy of disease code were location and level of the medical institutions in multiple logistic regression analysis. Medical institutions in Seoul showed lower accuracy than those in Kyonngi, and so did general hospitals, hospitals and clinics than tertiary hospitals. Physician related characteristics significantly lowering disease code accuracy of insurance data were sex, age group and specialty. Male physicians showed significantly lower accuracy than female physicians; thirties and fortieg age group also showed significantly lower accuracy than twenties, and so did general physicians and other specialists than internal medicine/pediatric specialists. This study strongly suggests that a series of policies like 1) establishment of peer review organization of National Medical Insurance data, 2) prompt nation-wide expansion of computerized claiming network of National Medical Insurance and 3) establishment and distribution of objective diagnostic criteria to physicians are necessary to set up a national disease surveillance system utilizing National Medical Insurance claims data.
