본 연구는 협동학습에서 팀 프로젝트를 수행하는 공대생들을 대상으로 학습양식유형 및 셀프리더십이 팀 수행 성적과 어떤 관련성이 있는 지를 파악함으로써 협동학습 효과의 극대화를 위한 기초소양교육 프로그램을 구성하는 데 도움이 되는 기초정보를 제공하기 위해 수행되었다. 팀 수행 성적이 상, 하위 30%에 해당하는 집단 간에 학습양식유형의 분포를 비교한 결과, 상위권 집단의 약 70%가 수렴자와 적응자에 해당된 반면, 하위권 집단의 약 67%가 적응자와 분산자에 해당되었다. 또한 상위권 학생들의 셀프리더십이 전반적으로 높았고, 특히 자기관찰, 자기처벌, 자연적 보상, 성공적 수행 상상하기, 자기대화, 신념과 가정분석 전략을 더 잘 실천하는 것으로 나타났다. 마지막으로 본 연구의 제한점과 후속연구를 위한 제언이 논의되었다.

Purpose: This study aims to investigate the effects of an intervention of self-feeding for elderly residents who were eating with assistance or eating by himself/herself with spilling food. Methods: The Participants were 11 elderly people and 6 formal caregivers from 7 nursing homes in Korea. The intervention was to use the spoon and chopstick sets designed for compensating the weakened eating function. Both quantitative and qualitative data were collected through observation, structured questions, and in-depth interviews. Results: The mealtime was significantly increased by 3.2 minutes (p=.011) after the intervention. Three themes were extracted for the meaning of self-feeding expressed by the elders; fighting alone for self-feeding, pride of participating in the study, and burden for self-feeding and research participation. Caregivers expressed the meaning of the elder's self-feeding such as the regret of missed chances, facilitating rehabilitation, the increase of the eating pleasure and quality of care, and ambivalence. Conclusion: Self-feeding has become an opportunity to recognize life values for the elders in nursing homes; for the caregivers, to reconsider caring of the elderly. Posture and eating utensils were also important to improve self-feeding skills.

Purpose: This study was done to evaluate depression in child cancer survivors. Methods: The participants in this descriptive research were 103 adolescents who agreed to participate. All of the adolescents were diagnosed as completely cured but remained under follow-up observation as outpatients. A structured questionnaire including the depression scale developed by Shin et al. (1991), a self-esteem scale developed by Rosenberg (1965) and a social support scale developed by Kim & Park (1999), Lee (1997) were used for data collection. The data were analyzed using SPSS. Results: The mean scores were, for self-esteem, 36.01, for paternal support, 57.21, for maternal support, 59.98, for peer support, 22.19, for teachers support, 21.07 and for depression, 27.95. Scores for depression were significantly different according to academic achievement, satisfaction with appearances, diagnosis and prognosis. Depression was negatively correlated with self-esteem, paternal support, maternal support, peer support, and teachers support. Variables affecting depression were peer support and self-esteem, accounting for 47.0% of the variance. Conclusion: The findings indicate that peer support and self-esteem, follow by maternal, paternal and teachers support, are important variables in the occurrence of depression in these adolescents. Further study is needed to develop strategies to increase this support and self-esteem.

This study aimed to confirm the usefulness of a "Traditional Play Program" in a self-esteem and social competency enrichment program at a Community Child Center. The subjects of this research comprised 12 children attending L Community Child Center in M city and participated in a "Traditional Play Program" for each 70minutes every week through total 10 sessions running from July 28th to September 29th in 2014. The collected data were analyzed by the Mann-Whitney & Wilcoxon test as non-parametric test, in addition to the progressive recording method for behavior observation. The results of this study indicate that a "Traditional Play Program" enriches the self-esteem and social competence of children who gets more vigorous activity sociality initiative respectively, and proves the usefulness for a Community Child Center.

Nowadays, a strategy of the self-optimizing machining process is an imperative approach to improve the product quality and increase productivity of manufacturing systems. This paper presents a concept of self-optimizing forming system that allows the forming system automatically to adjust the forming parameters online for guarantee the product quality and avoiding the machine stop. An intelligent monitoring system that has the functions of observation, evaluation and diagnostic is developed to evaluate the pully quality during forming process. Any abnormal variation of forming machining parameters could be detected and adjusted by an intelligent control system aiming to maintain the machining stability and the desired product quality. This approach is being practiced on the pully forming machine for evaluating the efficiency of the proposed strategy.

In this paper, we used the V-Q Lissajous‘ figure for studying on the plasma discharge characteristics of the 42 inches AC-PDP. From the V-Q Lissajous‘ figure, we could observe exactly the driving conditions that the self-erasing discharge takes place. At the time, the total wall charges lessened by self-erasing discharge was calculated quantitatively. Beside of the just observation of self-erasing discharge and calculation of the charges lessened, we could find out the optimum driving conditions for inducing the maximum wall charges accumulated on the dielectric layer with measuring the Wall voltage from the V-Q Lissajous' figure.

We present the development of a remote observation system runnig on world wide web (WWW). The system consists of a 30cm Schmidt Cassegrain telescope and ST-7 CCD camera. We built the controllers and drivers of the telescope and the control softwares including the network control. The self-developed techniques in the hard wares and softwares can be applied to other projects in Korea. Observers can access the system via WWW home page, to reserve observation times, to send control commands, to retrieve images and various information useful for observation. This system can be widely used by students and amateur astronomers as well as professional astronomers who need a lot of small telescope time.

Objective: The adhesion capabilities of different types of self-ligating brackets were measured with respect to Streptococcus mutans and Streptococcus sobrinus. Methods: Five types of self-ligating brackets (Clippy-C; Mini Clippy; Clarity-SL; Speed; Damon 3) were used for the experiment group and composite resin brackets (Spirit-MB), metal brackets (Victory) and polycrystalline alumina brackets (Clarity) were used for the control group. In order to assess adhesion of bacteria to the brackets, the brackets were cultured for 3, 6 and 24 hours in media containing bacteria and 20% sucrose. Results: There was no statistic difference in adhesion amount of Streptococcus mutans and Streptococcus sobrinus according to the types of brackets. A total adhesion amount according to bracket type was different. An extended incubation time increased adhesion amount. Observation under scanning electron microscope showed that Streptococcus sobrinus adhered more to Clippy-C and Victory rather than to Clarity-SL. Conclusions: Clarity-SL, a self-ligating esthetic bracket was confirmed to show lower bacterial adhesion to cariogenic bacteria, Streptococcus mutans and Streptococcus sobrinus group than other self-ligating brackets or conventional brackets, which suggests that proper use of self-ligating esthetic brackets might even be better in preventing tooth surface decalcification.

Purpose: The purpose of this study was to identify the relationship of clinical competency and self-directed learning in nursing students. Method: This study was conducted at two nursing colleges with students in a 2 year undergraduate nursing program. Data were collected from 182 students by means of self reporting questionnaires from October 1 to October 8, 2004. The data were analyzed by SPSS 10.0 PC programs using descriptive statistics, one-way ANOVA, Pearson correlation coefficient. Result: The questionnaire of students' clinical competency consisted of nineteen items based on a five point summated rating scale and was categorized into six subscales by factor analysis. The six subscales are nursing process, major nursing intervention, education for clients, observation and physical examination, and fundamental nursing. The more adaptable to major, the higher clinical competency (F= 3.406, p= .035) and self-directed learning (F= 7.444, p= .001). There was a positive correlation between students' clinical competency and self-directed learning (r= .367, p= .001). Conclusion: we concluded that future research should explore strategies for the development of self-directed learning to improve clinical competency of nursing students.
