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.

Purpose: This study was performed to review the recent experiences of pediatric gastrointestinal (GI) endoscopy done in one university hospital. Methods: A retrospective review of medical records was conducted of 1,040 pediatric cases who underwent GI endoscopy at the Pusan National University Hospital between January 2001 to June 2005. Results: A total of 1,040 endoscopies (upper 840 and lower 200) were performed. The male/female ratio was 1.25:1. Neonates and infants accounted for 6.0% and 16.5% respectively. Half of the children were below 5 years (mean age $8.5{\pm}2.1$ years). Upper and lower GI diagnostic endoscopies were performed in 634 and 163 children respectively. Abdominal pain (38.8%), vomiting (19.4%), foreign body (17.7%), and hematemesis (10.3%) were the main reasons for esophagogastroduodenoscopy. Hematochezia (56.0%), abdominal pain (27.5%) and diarrhea (3.0%) were the main reasons for colonoscopy. Upper GI therapeutic procedures included retrieval of foreign bodies, balloon dilatations of esophageal stricture, PEG, and variceal ligation in 148, 27, 15, and 3 children, respectively. Therapeutic lower GI endoscopies were performed in 37 children (polypectomy in 92%, argon lazer cauterization for angiodysplasia in 4%). Conclusion: GI endoscopy played an important role in the diagnosis and treatment of GI diseases in children. Procedures in younger aged children, cases evaluated by colonoscopy and therapeutic endoscopies are increasing in pediatric practice.

In this study, we investigated the effects of individualized learning adapted to students' conceptions using smart devices in science instruction upon students' conceptual understanding, the retention of conception, achievement, learning motivation, enjoyment of science lessons, and perception about individualized learning using smart devices. Four seventh-grade classes at a coed middle school in Seoul were assigned to a control group and a treatment group. Students were taught about molecular motions for seven class periods. Two-way ANCOVA results revealed that the scores of a conception test, the retention of the conception test, a learning motivation test, and an enjoyment of science lessons test for the treatment group were significantly higher than those for the control group. Although the score of the treatment group was higher than that of the control group in the achievement test, the difference was not statistically significant. Students' perceptions about individualized learning using smart devices were also found to be positive.

신뢰도 높은 소프트웨어 개발의 필요성은 전혀 새로운 것이 아니다. 요즘 들어, 소프트웨어의 크기와 복잡도가 증가함으로 인해 소프트웨어의 결함 때문에 발생하는 시스템 고장이 전체 시스템 고장에서 많은 비중을 차지하고 있다. 고 신뢰도를 요구하는 시스템의 소프트웨어는 복구블록, 분산 복구블록, N-버전 프로그래밍, N 자기검사 프로그래밍과 같은 소프트웨어 결함허용 기법들을 사용하고 있다. 이러한 소프트웨어 결함허용 기법들에 대한 연구와 함께 소프트웨어 결함허용 기법들의 의존도 측정에 관한 연구 또한 매우 중요하다. 이에 본 논문에서는 마르코프 모델을 사용해서 소프트웨어 결함허용 기법들의 보다 자세한 신뢰도 모델링과 가용도, 안전도 등에 관한 모델링을 제시한다. 제안된 모델 분석 결과 같은 수의 대체블록이 있을 때는 분산 복구블록, 복구 블록, N 자기검사 프로그래밍, N-버전 프로그래밍 순으로 의존도가 높음을 알 수 있다. 또한 소프트웨어 결함허용 기법들의 신뢰도민감성 분석에서는 복구블록과 분산 복구블록인 경우는 적응검사의 결함발생율에, N-버전 프로그래밍인 경우는 프로그램 버전의 결함발생율에 더 민감한 영향을 받는 것을 알 수 있다.

유비쿼터스 환경에 대한 관심이 높아짐에 따라 모바일에 관련된 하드웨어 개발은 물론 소프트웨어에 대한 관심도 마찬가지로 높아지고 있다. 소프트웨어에 대해 높아지고 있는 관심 중에서도 자원의 공유 혹은 접근에 대한 보안은 매우 중요한 이슈로 떠오르고 있다. 본 논문에서는 유비쿼터스 소프트웨어를 개발하기 위한 더 나은 프로그래밍 환경을 제공할 수 있는 정책 기술 언어로 작성된 정책 명세에 포함되는 권한의 제어를 위한 접근 제어 규칙(Access Control Rule)과 변화되는 상황을 감지하기 위한 상황 적응 규칙(Adaptation Rule)을 검사하여 규칙 사이의 안전성을 검사하기 위한 방법을 제시한다. 또한 규칙 사이의 안전성을 말하기 위해 사용되는 타입 시스템에 대해서도 설명한다.

검사점(checkpoint) 오버헤드를 최소화하는 검사점 주기(interval)를 결정하는 것은 결함 허용 시스템(fault tolerant system)에서 검사점 알고리즘과 관련된 많은 연구들의 중요한 목표 중의 하나이다. 검사점을 드물게 하게 되면 실패 후에 재수행 하는데 너무 많은 시간이 필요하게 된다. 반면에, 너무 자주하게 되면 검사점 오버헤드가 커지고 프로그램의 총 실행시간에 영향을 주게 된다. 이 논문에서는 적응성 있는(adaptive) 시계열 (time series) 분석을 사용하여 검사점 간격을 동적으로 조절할 수 있는 메모리 프로파일 검사점 간격 알고리즘을 제안한다. 트레이스에 기반한 시뮬레이션 실험 결과에서. 제안한 동적인 검사점 주기 알고리즘이 고정적인 검사점 주기 알고리즘보다 전체 검사점 오버헤드가 더 작고, 최적의 검사점 간격에 훨씬 근접했음을 알 수 있었다.

This study is about the effects of the solution-focused group art therapy which was implemented for school maladjusted adolescents. The pre-test was conducted for 30 students who had difficulties to adapt school life in K middle school at K city, Gyeonggi province. 20 out of the 30 students were chosen to the participants for this study and randomly divided into an experimental group and control group, with 10 in each group. The experimental group received a 12 session solution-focused group art therapy including pre- and post-tests. This study found that the solution-focused group art therapy program improved the school life adaptation competency of the participants. In conclusion, the findings suggest that the solution-focused group art therapy can be a good approach to help adolescents to improve their school life adaptation ability.

In this study, we have developed a web-based adaptive testing system using item response theory´s computerized adaptive testing to diagnose underachievers, and to check the evaluation results immediately. Adaptive testing system simple is not the fact that it presents a question to students. It calculates information of a question and presents the question to students. It controls the response of the students under extraction conditions of the next question. It extracts the question which is the most suitable it presents. In this adaptive testing system, you can extract questions according to the level of the students, and adjust the length and the level of the difficulty according to the response of the students.

The purpose of this study was to investigate the influence of college adjustment and social support on career development for college students majoring in health or social welfare. For this purpose, a survey was conducted in the Gyeongsangnam-do area. There was a total of 203 study participants. Data were collected with a set of questionnaires and analyzed by a multiple regression analysis. The results of this study are summarized as follows. First, the mean of main variables are as follow; career development was 3.54, college adjustment was 3.07, social support was 3.59. Second, by using a multiple regression, college adjustment and social support had a positive effect on career development. In other words, higher the college adjustment and higher the social support, the higher the career development. Third, academic adjustment among the sub-areas of college adjustment and friend support among the sub-areas of social support had a significant effect on career development level. Based on these results, implications for research and practice were discussed.

As the demand for LCD increases, the importance of inspection equipment for improving the efficiency of LCD production is continuously emphasized. The pattern inspection apparatus is one that detects minute defects of pattern quickly using optical equipment such as line scan camera. This pattern inspection apparatus makes a decision on whether a pixel is a defect or not using a single threshold value in order to meet constraint of real time inspection. However, a method that uses an adaptive thresholding scheme with different threshold values according to characteristics of each region in a pattern can greatly improve the performance of defect detection. To apply this adaptive thresholding scheme it has to be known that a certain pixel to be inspected belongs to which region. Therefore, this paper proposes a region matching algorithm that recognizes the region of each pixel to be inspected. The proposed algorithm is based on the pattern matching scheme with the consideration of real time constraint of machine vision and implemented through GPGPU in order to be applied to a practical system. Simulation results show that the proposed method not only satisfies the requirement for processing time of practical system but also improves the performance of defect detection.
