The purpose of this study was to analyze the converged influencing factors on the stages of exercise behavior changes in shift work nurses. The subjects were 120 shift work nurses working in hospitals who understood the purpose of the study and agreed to participate in the study. Data were analyzed using frequency, percentage, mean, standard deviation, t-test, $X^2$ test, and multiple logistic regression analysis. The exercise motivation factors of shift work nurses had a significant effect on stages of exercise behavior change (${\beta}=2.480$, p=.022), health status perceptions(${\beta}=1.151$, p=.013). Social support factors (${\beta}=1.819$, p=.002) and marital status (${\beta}=-1.820$, p=.004) also had significant effects on the stages of exercise behavior change of shift work nurses. In other words, subjects with change in exercise behavior had 11.9 times higher motivation and 3.1 times higher health status perception than those without change in exercise behavior, social support was 6.1 times higher, and unmarried subjects showed 16 times showed higher than that of married subjects.

본 논문에서는 DSP Group사의 16 비트 고정 소수점 DSP인 OaKDSP Core를 사용하여 유럽의 이동통신에서 표준으로 사용되고 있는 음성 부호화기 알고리즘인 GSM-EFR (Global System for Mobile communications -Enhanced Full Rate) 을 실시간으로 구현하였다. 구현된GSM-EFR 음성 부호화기의 계산량은 약 24 MIPS가 소요되며, 7.06K 워드의 코드 메모리와 12.19K 워드의 데이터 메모리를 사용하였다. 구현된 음성 부호화기는 ETSI에서 제공하는 시험 벡터 샘플을 모두 통과하였으며, 객관적 평가 툴을 이용하여 지각 평가를 수행한 결과, 32kbps ADPCM과 비슷한 음질을 보였다. 본 논문에서 실시간으로 구현된 GSM-EFR 음성 부호화기는 IMT2000 비동기 방식의 음성 부호화기 표준인 GSM-AMR의 최상위 전송률 모드로서. 앞으로 IMT-2000 비동기식 단말기용 모뎀 ASIC에 탑재할 GSM-AMR 음성부호화기의 구현을 위한 기본 구조로 이용될 예정이다.

The achievement motivations of science gifted students are very important in becoming experts who achieve high level. In this study, 77 8th graders of Science Gifted Education Center were divided into highly motivated and low motivated groups. Multidimensional Perfectionism, Self-Concept, Parenting Behaviors Scale were compared between these 2 groups, and predicting variables were verified through regression analysis. As a result, highly motivated students received higher scores on Perfectionism, self-directed Perfectionism, and other-directed Perfectionism. Self-concept scores were higher on factors of body, moral, personalities, social, and abilities as well. In Parenting Behaviors Scale, only the father's affection factor was influenced. The result of regression analysis revealed that self-directed Perfectionism, social self-concept, and moral self-concept had meaningful predictions. In parameter verification, partially mediated effect of self-directed Perfectionism and social self-concept was verified in the relationship between father's affection factor and achievement motivation. This study confirmed that self-directed Perfectionism of science gifted students has positive effects on adaptation. The importance of social and moral education and the father's affection were found as well.

적응적 웹기반 기법에서 학습자의 반응이나, 탐색 행동의 근본적인 원인이 되는 학습 동기, 지각 등에 대한 판단을 정확히 할 수 없기 때문에, 학습자에게 완전히 적응적인 수업 환경을 조성해 주는 데는 한계가 있다. 이러한 한계를 극복하기 위한 대안으로 학습자간 상호작용이나 협동 학습을 지원하는 웹기반 교수 시스템이 제안되고 있다. 본 논문에서는 웹기반 환경에서 학습자들간의 협동학습을 효과적으로 지원하는 적응형 교수 시스템을 제안한다. 본 시스템은 협동학습 공간에서 주어진 과제를 수행하기 위해 발생되는 학습자들의 대화와 서로간의 상호작용을 분석하여 적절한 조언을 제공함으로서 협동학습이 효과적으로 이루어 질 수 있도록 지원한다.

The results were as follows. First, emotion, home environment, school environment were correlated with on motivational and behavioral regulation. Second, emotion explained motivational regulation and behavioral regulation of self-regulated learning as well as home envionment and school environment. All subvariables of emotion were significantly related to behavior control. Third, among subvariables of home environment, parents education and occupations, and annual household income were not significantly related to motivational regulation and behavioral regulation. However, home economic level perceived by students and parents' interest and abuse on students had great effects. Forth, school environment has a greater explanatory effect on motivational regulation and behavioral regulation. Particularly, friendships and relationships with teachers during learning activities had a significant effect. These results showed that emotion and psychological environment of learning environment are important variables affecting on self-regulated learning and suggests the need for researches on these variables.

To ensure continued existence, an organization must develop ways to share the knowledge that is possessed within the organization with the people who need, or who will need, that knowledge. Improving the efficiency of knowledge sharing is a highly desirable goal, but the issue of how best to motivate individuals to share their most valuable knowledge is not yet completely resolved. This paper aims to provide a sharing model on job related knowledge. Also, it intends to look for the factors that facilitate knowledge sharing among individuals in an organization. The research model is based on the technology acceptance model and it includes the perceived usefulness, perceived ease of use, attitude and intention to share constructs. Also, two external variables namely organizational culture and system quality were added. However, the actual use was excluded. In the research model, all hypotheses were found to be significant except one, which is the hypothesis that perceived usefulness will positively affect the intention to share.

The purpose of this study was to examine the relationships between anger expression, social supports, and adjustment to college life among nursing students. A convenience sample of 266 students in two colleges participated in the study. Data were analyzed using t-tests, ANOVA, Pearson correlation coefficients, and multiple stepwise regression. The mean score for adjustment to college life was above average. The mean score for adjustment to college life differed significantly according to students' reasons for applying to college and perceived health status. Adjustment to college life significantly correlated with anger expression and social supports. Multiple stepwise regression analysis showed that anger expression (Anger-Out, Anger-In, and Anger-Control), social supports, and perceived health status explained 27.1% of the variance in adjustment to college life. The study findings suggest that interventions intended to promote nursing students' adjustment to college life should focus on improving anger management, social supports, and perceived health status.
