The dramatic increase in e-Learning enrollments in higher education is likely to continue. These e-Learning environments have made learning much more convenient by stretching the spatial and temporal barriers. Their effectiveness, however, remains to be examined. In this research, the author explore the importance of personalization, interactivity and the important role of contents organizing in online education environment. Furthermore, the authors divide e-learning outcome into psychomotor, cognitive, and affective outcome. Indeed, e-Learning for psychomotor outcome has been viewed as impossible. The authors discuss the implications of the findings for theory and practice.

In this paper, we propose a dynamic emotion system involving the state equation and the output equation from the control theory. In our emotion system, the state equation accepts external stimulus and generates emotions. And the output equation modifies the intensity of emotions in accordance with personalities and circumstances. The validity of the proposed emotion system is shown by two simulation works which express emotions according to personalities and circumstances.

Objectives: This study aims to examined whether physical activity prevent the negative effect of psychological stress on cardiovascular reactivity by reducing stress induced sympathetic output and preventing norepinephrine depletion negative psych-affective responses. It is assumed that physical activity reduces the magnitude of cardiovascular responses and psychological responses to stress which threaten individuals' physical and mental health. The result of investigating the effect of physical activity on reducing negative physiological and psychological responses would suggest useful information health for practitioners who want to prevent stress-induced diseases, especially coronary heart disease. Methods: participants of this study were 30 students (10 males & 20 females), whose mean age was 21.30 (SD=2.29). Fifteen students (5 males & 10 females) were assigned for in each group, treatment and control groups. They were interviewed and given a survey that included a consent form, demographics sheet and psychological tests, such as State-Trait Anger Expression Inventory and State-Trait Anxiety Inventory. Before the application of psychological stress, participants in treatment group were going through with a course of physical exercise, running on treadmill 15minutes, while participants in control group were not physically active. After exercise, there was 15 minutes resting period before applying cognitive stress. During the experiment, all participants performed challenging cognitive tasks for 20minutes in situations that were designed to experience learned helplessness and measured their cardiovascular reactivity including blood pressure and heart rate every 5 minutes, until 10 minutes after finishing the application of psychological stress(recovering state). In the end of experiment, they were given some psychological test again. Results: Heart rates of exercise group were significantly higher than non-exercise group, especially, five minute after applying cognitive stress and at the end of recovery, in other word 10 minutes after stressful event. Systolic blood pressures of exercise group were lower than those of non-exercise group during the stressful event, but this differences in borderline level of significance. state anger level of exercise group decreased even experiencing stress, while those of non-exercise group increase. And state anxiety level of exercise group decreased in borderline level of significance. Conclusion: This study reiterate health benefits of physical activity and suggest that regular moderate exercise may regulate cardiovascular reactivity and psycho-affective responses from stress by reducing stress induced sympathetic output.

급격한 환경변화에 속에서 창의성이 조직 생존을 위한 경쟁우위 요인으로 강조된 이 후, 많은 학자들은 어떻게 하면 창의성을 향상시킬 수 있는지에 대해 관심을 가져왔다. 수많은 조직들이 효율적인 업무처리를 위해 팀 제를 도입하고 있는 현 상황에서 팀 창의성에 대한 관심 역시 증가하는 추세이다. 본 논문에서는 팀 창의성에 대한 이해를 목표로 팀 학습목표 지향성을 선행요인으로 고려한다. 특히, 팀 학습목표 지향성과 팀 창의성 사이의 관계를 설명하는 서로 다른 팀 프로세스(예, 팀 성찰, 팀 효능감, 긍정적 집단 정서 분위기(PGAT: Positive Group Affective Tone, 이하 PGAT))를 밝히는데 목적을 둔다. 본 연구의 분석 자료를 수집하기 위해 서울소재의 한 경영대학에서 개설하는 세 개의 경영학 전공 강좌의 수강생 187명(57개 팀)을 대상으로 설문조사를 실시하였으며, 위계적 회귀분석을 방법을 사용하여 자료를 분석하였다. 분석 결과, 팀 학습목표 지향성은 팀 창의성과 정(+)적으로 관련하는 것으로 나타났으며, 팀 성찰과 팀 효능감을 정(+)적으로 예측하였다. 또한, 팀 성찰과 팀 효능감은 팀 창의적 성과를 유의미하게 예측하였으며, 동시에 팀 학습목표 목표 지향성과 팀 창의성 사이를 매개하는 사실을 확인할 수 있었다. 하지만, 예측과 달리 PGAT는 팀 학습목표 지향성과 팀 창의성과는 통계적으로 관련성이 없는 것으로 나타났다. 이와 같은 본 연구 결과는 다양한 이론적, 실무적 시사점을 가진다.

본 연구에서는 교육과정 질 관리의 측면에서 의무교육 대상인 초등학교와 중학교의 수학 교육 실태를 분석하여 교육과정의 투입, 과정, 산출 단계의 측면에서 질 관리가 되어야 할 주요 내용을 중심으로 학생, 학부모, 교사 대상 설문을 실시하였다. 설문 결과, 첫째, 투입 단계에서 초등학생들은 학습량이, 중학생은 내용 수준의 어려움이 있음이 나타났다. 둘째, 과정 단계에서 초등학교 교사들이 중학교 교사들에 비하여 교육과정 상의 교수 학습 방법을 더 잘 이행하고 있는 것으로 나타났다. 셋째, 산출 단계에서 학생 및 학부모의 인지적 영역과 정의적 영역의 만족도가 초등학교보다 중학교에서 낮은 것으로 나타났지만, 응답 평균은 두 학교급에서 모두 높은 편이었다. 이상을 고려하여 추후 새교육과정이 교육 현장에 적용될 때에 학교급별로 나타난 문제점을 해소할 수 있는 방법이 마련되어야 하고, 궁극적으로 교육과정 질 관리를 위한 수단으로서 교육과정이 개정될 수 있는 체제가 마련되어야 할 것이다.

Beat-to-beat changes in heart period (heart period variability, HPV) are mediated by fluctuations in autonomic activity. Spectral analysis is used to quantify such fluctuations in the range of 0.15-0.40 Hz (high frequency, HF), which are influenced primarily by parasympathetic factors. These fluctuations are often referred to as RSA (respiratory sinus arrhythmia), the physiological phenomenon extracted by spectral analysis and other methods including histograms of heart rate ( HR), deviations of HR etc. Respiratory sinus arrhythmia indexing with peak-to-valley method suggested by Grossman et at., (1981) yields a simple range statistic and is quantified on breath-by-breath basis, thus being quite sensitive and less dependent on recording time as compared to spectral analysis. It is strongly recommended to use at least 1 min epoch to asses HF component of HPV and at least 2 min fer low frequency (LF) of HPV and even 5 min far valid clinical assessment. Peak-to-valley statistic is limited to RSA index only, but has its pragmatic advantages. Most important is possibility of its application far relatively small epoch analysis. We used short periods (20,30, 40 sec only) and off-line analysis of RSA using ECG and respiration curve this method of assessment and proved that this method is more practically effective. The RSA index was not so far dependent on respiration pattern differences and reflected actual vagal control of HR and were accompanied by low HR under some high stress conditions and in an aversive affective visual stimulation experiments. Another factor that might modulate cardiac chronotropic response is the interaction of sympathetic and parasympathetic inputs on sino-atrial (SA) node level, because responses to vagal influences are known to be proportional to ongoing sympathetic activity, that is so called accentuated antagonism. Since sympathetic outflow (increment of influences on SA) under negative emotions or stress was high in almost all physiological responses, vagal effects on HR could be therefore potentiated, leading to masking of output cardiac response seen in HPV, In the case of moderate sympathetic activation, on the other hand, autonomic interactions in cardiac control appear to be minimal. Thus RSA index appears to be an effective alternative method to assess and measure spectral HPV.
