소프트웨어 결함 예측 연구들의 대부분은 라벨 데이터를 훈련 데이터로 사용하는 감독형 모델에 관한 연구들이다. 감독형 모델은 높은 예측 성능을 지니지만 대부분 개발 집단들은 충분한 라벨 데이터를 보유하고 있지 않다. 언라벨 데이터만 훈련에 사용하는 비감독형 모델은 모델 구축이 어렵고 성능이 떨어진다. 훈련 데이터로 라벨 데이터와 언라벨 데이터를 모두 사용하는 세미 감독형 모델은 이들의 문제점을 해결한다. Self-training은 세미 감독형 기법들 중 여러 가정과 제약조건들이 가장 적은 기법이다. 본 논문은 Self-training 알고리즘들을 이용해 여러 모델들을 구현하였으며, Accuracy와 AUC를 이용하여 그들을 평가한 결과 YATSI 모델이 가장 좋은 성능을 보였다.

The object of this study is to inspect how much influence the play-based assertive training program has on the self-expression and learning attitude of elementary students. To perform this study, I set up two subjects of research. First, does the play-based assertive training program have influence on the self-expression improvement of elementary students? Second, does the play-based assertive training program have influence on the attitude of elementary students? I established 28 students in the third grade of K elementary school in Gongju City as experiment group for this research. In experiment group, 1 peformed play-based assertive training program in the class of discretion and extra-curricula activity twice a week and maintained the program for 6 weeks. By the standard of 12 times of performances, I put pre-test and post-test into operation. The major consequences revealed through above processes are followed: First, as the consequence of analyses of differences between pre-test and post-test about self-expression of experiment group adapted by play-using assertion training program, the level of self-expression was advanced meaningfully. Second, as the consequences of analyses of differences between pre-test and post-test about learning-attitude of experiment group adapted by play-based assertive training program, the level of learning-attitude was advanced meaningfully. Among 8 sub-fields of learning attitude, the field of superiority, accomplishment motives, concentration, self-study show statistically meaningful difference s respectively. The conclusion drawn from above consequences is that the play-based assertive training program is very effective in developing students' self-expression and attitude for learning.

Purpose: The aim of this study was to evaluate differences of pre-post simulation training in problem solving ability, performance confidence, and critical thinking skill according to degree of nursing students' self-leadership. Methods: This study was a descriptive survey using a self-report questionnaire. One hundred eighty nursing students participated in this study which programed a simulation scenario of pre-post operative patients' care. Descriptive statistics, paired t-test, ANCOVA with IBM SPSS 21.0 program were used for data analysis. Results: After the simulation training, both the above-average subjects and below-average subjects in self-leadership significantly improved their problem-solving ability, performance confidence, and critical thinking skill. compared with their previous level. The subjects who rated above-average in self-leadership, improved their degree of problem-solving ability, performance confidence, and critical thinking skill significantly more than those who were below-average in self-leadership. Conclusion: Self-leadership of nursing students is an important element in effective simulation training.

Training in self-expression was provided 24 times over 8 weeks for 5-year-old children in two classes in A kindergarten at an elementary school located in G metropolitan city. The posttest conducted at the conclusion of the training session confirmed significant statistical differences between the two groups. All the subfields on initiative, such as emotional ability, communication, and achievement motivation showed significant differences between groups.

본 논문에서는 홈트레이닝에 참여하여 체력을 단련하고 있는 경찰관련학과 학생들의 자기결정성과 홈트레이닝 만족도와 재이용과의 관계를 알아보고자 하였다. 이를 위해 부산, 경남지역 D, S, K대학교 경찰행정학과, 경찰무도학과 재학생중 홈트레이닝에 참여한 경험이 있는 학생 349명을 대상으로 조사하였다. SPSSWIN VER 25+, AMOS 20.0 프로그램을 이용하여 자기결정성, 운동만족, 재이용 요인간의 관계를 검증한 결과, 첫째, 홈트레이닝 참여자의 자기결정성 하위요인인 자율성, 유능감, 관계성은 홈트레이닝 만족도에 긍정적인 영향을 미쳤다. 둘째, 홈트레이닝 참여자의 운동만족은 홈트레이닝 재이용에 긍정적인 영향을 미쳤다.

The purpose of this study was to investigate the effects of a winter training camp on physical fitness, physical self-efficacy and nutrients intake in juvenile Taekwondo players. Sixty three subjects of male middle school student Taekwondo players participated in this study. Before and after attending Taekwondo winter training camp, Taekwondo related fitness and physical self efficacy and nutrients intake of subjects were measured and compared. The results of this study were as follows: 1) There were significantly improvements (p<0.001) in 1200m run, sit up, push up. 2) There was no significantly change in physical self efficacy. 3) There were significantly increase intakes (p<0.001) in total calorie, protein, fat, fiber, Ca, P, K, vitamin A, vitamin B2, vitamin B6, niacin, vitamin C and vitamin E. However, index of nutritional quality in fiber, Ca, K, vitamin A had not good assessment. These results suggested that a winter training seems necessary to keep psychological management and scientific dietary management as well as physical training in juvenile Taekwondo players.

Previous studies on user training have largely focused on assessing models which describe the determinants of information technology usage or examined the effects of training on user satisfaction, productivity, performance, and so on. Scant research efforts have been made, however, to examine those effects of training by using theoretical models. This study presented a conceptual models to predict intention to use information technology and conducted an experiment to understand how training for computer skill acquisition affects primary variables of the model. The data were obtained from 32 student subjects of an experimental group and 31 students of a control group, and the information technology employed for this study was a university electronic mail system. The study results revealed that attitude toward usage and perceived behavioral control helped to predict user intentions ;; outcome expectations were positively related to attitude toward usage ; and self-efficacy was positively related to perceived behavioral control. The hands-on training for the experimental group led to increases in perceived ease of use, self-efficacy and perceived behavioral control. The changes in those variables suggest more causal effects of user training than other survey studies.

In this paper, we describe self-training super-resolution. Our approach is based on example based algorithms. Example based algorithms need training images, and selection of those changes the result of the algorithm. Consequently it is important to choose training images. We propose self-training based super-resolution algorithm which use an input image itself as a training image. It seems like other example based super-resolution methods, but we consider training phase as the step to collect primitive information of the input image. And some artifacts along the edge are visible in applying example based algorithms. We reduce those artifacts giving weights in consideration of the edge direction. We demonstrate the performance of our approach is reasonable several synthetic images and real images.

본 연구의 목적은 초등학교 학생들을 대상으로 뇌파 자기-조절 뉴로피드백 훈련이 회상기억과 재인기억에 미치는 효과를 검토하는 것이다. 이를 위해 36명의 초등학교 학생들을 자기-조절 4 회기의 뉴로피드백 훈련을 받는 훈련집단과 이러한 처치가 제공되지 않은 통제집단으로 각각 18명씩 무선할당한 후에, 각 회기에 따라 회상기억과 재인기억 수행의 변화를 관찰하여 분석하였다. 그 결과 회상기억과 재인기억 모두 자기-조절 뉴로피드백 훈련집단이 통제집단에 비해 더 우수한 수행을 보였을 뿐만 아니라 훈련회기가 증가함에 따라 두 가지 수행치 모두 향상되는 것이 관찰되었다. 특히 기억해야 하는 표적단어의 수로 조작한 과제의 난이도가 증가 할수록 훈련 효과도 더 증가하였다. 본 연구의 결과는 자기-조절 뉴로피드백 훈련이 피훈련자의 주의력을 향상시켜 주요 인지과정 중 하나인 단어 기억 수행을 향상시키는데 도움이 될 수 있다는 것을 시사한다.
