Purpose: The purpose of this study was to examine the effects of the simulation-based cooperation program on self-efficacy, social problem-solving ability and college life adjustment of health college students. Methods: A nonequivalent control group pre-posttest design was used. Sixty-eight students were in the experimental group receiving the simulation-based cooperation program, and 68 were in the control group with no treatment. Results: There were significant increases in self-efficacy(z=-4.70, p<.001) and college life adjustment(t=2.03, p<.05) in the experimental group compared to the control group. However, there was no difference in the social problem-solving ability (z=-1.87, p=.061) between the experimental and control groups. Conclusion: The findings indicate that the simulation-based cooperation program has a significant effect on improving self-efficacy and college life adjustment in health college students. Thus the simulation-based cooperation program to promote the social problem-solving ability needs to be more developed and research related with cooperation program is further needed.

Delivering rich and continuous media contents robustly over a wide range of network conditions of the wired/wireless Internet is a highly challenging task. To address this challenges, the continuous media applications at the edge of network has become more and more adaptive while the best-effort Internet is slowly progressing towards improved networking services. That is, the role of network adaptive media delivery, which dynamically links the quality demand of application contents to the underlying networking services, has become more crucial. In this paper, we will first review the required network adaptation functionalities seen from the application side: congestion control / rate control, error control, and synchronization / adaptive playout. Then, we start the coverage of networking support issues that helps the realization of network adaptive media streaming - from network support and protocol support toward consolidated support via middleware. Finally, we propose a dynamic network adaptation framework that efficiently leverages its awareness of both media application (including contents) and underlying networking support.

The Purpose of this study was conducted to identify the effects of self growth group counseling program on the self-esteem and adaptation to school life of middle-school girls. The data were collected between November 2 and December 28, 2017. A total 24 middle-school girls at K city were participated. The collected data were analyzed using frequency, mean and standard deviation, t-test. Main results of this study were the experimental group showed significantly(p<.01) better score in the self-esteem test than the control group after taking program. And, the experimental group showed significantly better score in the teacher-student relation test(p<.05) and school classes test(p<.05) than the control group after taking program. This results suggest that there is a significance in presenting scientific evidence of self growth group counseling program. In addition, this study suggests the necessity that the self growth group counseling program for a variety of teenagers develops.

This paper suggests a new algorithm for detecting the plagiarism among a set of source codes, constrained to be functionally equivalent, such are submitted for a programming assignment or for a programming contest problem. The typical algorithms largely exploited up to now are based on Greedy-String Tiling, which seeks for a perfect match of substrings, and analysis of similarity between strings based on the local alignment of the two strings. This paper introduces a new method for detecting the similar interval of the given programs based on an adaptive similarity matrix, each entry of which is the logarithm of the probabilities of the keywords based on the frequencies of them in the given set of programs. We experimented this method using a set of programs submitted for more than 10 real programming contests. According to the experimental results, we can find several advantages of this method compared to the previous one which uses fixed similarity matrix(+1 for match, -1 for mismatch, -2 for gap) and also can find that the adaptive similarity matrix can be used for detecting various plagiarism cases.

The purpose of this study is to develop the prevention program of child abuse and to verify the effects of the program for marriage immigrant women in Korea. The prevention program was consist of 5 sessions and it was provided to participants once a week for five weeks. Participants were recruited thru the community centers for multi-cultural families in Korea. This study verified the effects of the prevention program with the comparison groups(pre-post). With the independent-samples t-test and paired-samples t-test, the program verified significant effects on the variables of acculturation stress, social support, and recognition of social policy. This study suggests the parenting education of child abuse for multi-cultural families in Korea.

기존 컴퓨팅 패러다임에서는 고정된 환경을 가정하여 소프트웨어를 설계하였으므로 급속한 시장 환경의 변화와 소비자의 불확실한 요구조건에 대응하여 개발하기에 어려움이 있다. 따라서 외부 환경의 변화를 직면하였을 때 동작을 멈추는 것이 아니라 그 변화를 감지하고 대안을 선택하여 지속적으로 서비스를 제공할 수 있는 자기 적응형 소프트웨어가 필요하다. 그러나 기존의 자기적응형 소프트웨어에 대한 연구는 적응형 소프트웨어에 영향을 주는 문맥정보를 모델링하는 기법이나 적응을 위해 대체할 수 있는 기능들을 찾아내는 방법에 대한 연구가 부족한 실정이다. 이 문제를 해결하기 위해 본 논문은 시나리오를 이용한 목표 기반으로 분석을 하고, 분석된 요구사항의 가변 수와 크기에 따라 프로그램의 문법뿐 아니라 사용자의 관점에서도 의미 있도록 프로그램 동적 슬라이싱 기법을 적용하도록 한다. 또한, 제안된 방법이 전 과정에 문맥에 대한 분석, 설계 정보가 반영되어 동적으로 재구성하는 방법을 제시하도록 한다.

The purpose of this study was to investigate the effects of ego-resilience and Spiritual well-being on college adjustment in nursing students. The sample for this study consisted of Nursing students from 2 university of nursing in C Provinces. The data were collected from November 10 to 17, 2014. The data were analyzed using t-test, ANOVA, Pearson correlation and multiple regression with SPSS 18.0. A positive correlation was found for college adjustment with Ego-resilience and Spiritual well-being. In addition Ego-resilience, Religious spiritual well-being, Existential spiritual well-being accounted for 39% of variance in college adjustment. The results of this study suggest that development of Ego-resilience and Spiritual well-being in nursing students is important to college adjustment. Further research in improving Ego-resilience and Spiritual well-being is warranted.

The purpose of this study was to investigate the effects of attachment injury and stsit-trait anxiety on marital adjustment of battered women. The participants were total 220 battered women who have experiences with violence from their spouse. Data were collected from March 20 to May 6 in 2014 from five shelters for battered women, seven counseling centers, and three shelters run by various religion. SPSS 18.0 was used for data analysis and descriptive statistics, ANOVA test, Scheffe's test, Pearson's correlation coefficients, and multiple regression were done. As study results, attachment injury, state and trait anxiety showed significant negative correlation. Marriage status, number of children, duration of violence, attachment injury, state anxiety, and trait anxiety were the significant variables to explain marital adjustment. The explanation power was 60.0%. This study results will be use to develop intervention program for enhancement of marital adjustment whereas to decrease attachment injury and state-trait anxiety.

The purpose of this study is to investigate the effect of applying a group art therapy program on self-esteem and stress for adolescents who are maladjusted to school. The subjects of this study were 6 school maladjusted adolescents enrolled in the second year of B middle school in A region, and the period was from May 12 to June 9, 2021, twice a week, for a total of 10 sessions of 60 minutes each. As a research tool, the Self-Esteem Scale(SEI) and the Person-In-The-Rain(PITR) were examined to observe the students. For data analysis, Wilcoxon test was conducted to examine the change in self-esteem, and the Person-In-The-Rain(PITR) was qualitatively analyzed to observe stress by two art therapists. The results of this study were first, that the group art therapy program had a significant effect on improving the self-esteem of adolescents and second, the group art therapy program was effective in reducing the stress. In conclusion, group art therapy can be seen to help improve self-esteem and reduce stress in school maladjusted adolescents.
