Object:The goal of this study was to examine the changes in body weight and glucose levels of the patients treated with risperidone, clozapine or haloperidol in order to compare the effect of risperidone or clozapine with that of haloperidol. Methods:For nine months(January to September, 2003), a prospective study was performed in 60 patients with chronic schizophrenia who were in Seoul National Hospital. Two-week period was required for a drug wash-out. The patients were randomly assigned to risperidone, clozapine and haloperidol groups. They were given risperidone(n=20), clozapine(n=20) and haloperidol(n=20), respectively, everyday for 12 weeks. To examine the effects of these drugs on body weight and fasting glucose levels, we measured body weight and glucose levels of all the patients first without the drug treatment and at each end of 4, 8, and 12-week periods with the treatment. And we examined the differences among three groups in the changes of body weight and fasting glucose levels. Results:There were no significant differences in the changes of the body weight and fasting glucose levels between the atypical antipsychotics(risperidone or clozapine) and the typical antipsychotics(haloperidol). Conclusion:The study in the patients with chronic schizophrenia suggests that risperidone or clozapine do not cause any additional effects on body weight or glucose levels compared to haloperidol.

This study was to analyze the learning effectiveness of multi-media based class by comparing with traditional classroom method. The "Distribution Working Subject" course that is one of the required courses of Vocational high school was selected and its contents were digitalized on MS Powerpoint for multi-media based class. The thirty students were sampled for each experimental and control groups. The homogeneity and learning achievement of sample groups were tested for experiment. Same teacher took the classes of two groups and delivered same contents of course. Only difference between two groups was the delivery method, one is traditional classroom teaching method and the other was the multi-media based class. The learning achievements and satisfaction of sample were post-tested in order to analyze the learning effectiveness by comparing two teaching methods. The results showed that there was a significant difference between experimental and control group in learning achievement after ANCOVA controlled pre-test as covariance(F=5.08, p<.05). It means that the learning achievement of multi-media based class was higher than that of traditional classroom group. The results also showed that a significant difference in students' satisfaction between two groups (t=5.57, p<.001). This study concluded that using multi-media in class could produce more learning achievements and satisfaction of students than traditional classroom method.

Quick and accurate learning of diverse electronic products has become an important daily task. In particular, software occupies core status in the control and operation of the products. This research tested the effects of learning method, schedule, and task difficulty in the learning of software. Using 2 (learning method: experiential vs. verbal) ${\times}$ 2 (learning schedule: spaced vs. massed) ${\times}$ 2 (difficulty: easy vs. difficult) between-subjects design, Experiment 1 tested participants' learning of file control using Windows Movie Maker. There was no effect of learning schedule on task completion time, but participants in experiential learning were faster in the completion of evaluation task compared with those in verbal learning condition. Importantly, as task difficulty increases participants in verbal condition showed markedly lower performance than those in experiential condition, which suggests that experiential learning is more effective with more difficult learning task. That is, in case of learning simple operation of software verbal learning using linguistic manual or instruction could be sufficient; on the other hand in case of learning complex operation learning from experience or tutorial mode would be more effective. Additional studies which manipulated task difficulty (Expt. 2) and inter-trial learning interval (Expt. 3) did not produce meaningful results.

Using the AUDIT-K (Korean versions of alcohol use disorders identification test), it was able to select a large number of potential danger drinkers who routinely live. There were no statistically significant differences in age, religion, marital status, occupation, family history of alcohol drinking, age at onset of alcohol use, smoking, and BMI (body mass index). However, only education and drinking periods were statistically significant. These results are consistent with the previous study, which suggests that alcohol consumption is higher among men who are educated. The level of education also suggests that there is a need to look at the differences depending on what you learned and how. Alcohol consumption by education also shows different results. Also, drinking at a young age will lead to a longer drinking period, which is consistent with previous studies on the age at onset of drinking. In this study, drinking period was the most important factor of alcohol use disorder and it is considered that measures and education of national government system which can delay drinking age as much as possible is needed as a method to shorten drinking period.

This study is aimed to investigate that the blended e-learning could enhance the effectiveness compared to the conventional lecture performed in classroom. At first, both the CbE(Class based E-learning) and the EbC(E-learning based Class) mode have been generated in blended e-learning operation method following the process which analyze the various studies of interest. In addition, the instruction structures of Z Type(Zigzag model) and H-Type(Ladder model) were established as proposed model. The H-Blended e-learning based on CbE mode was introduced in the Excel Spread Sheet subject which held in A University to achieve the goal of this study. Learners were categorized and belonged to either the group 1(over 50% of attendance in cyber lecture) or the group 2(the rest of them). The data analysis was performed with $x^2$-test, t -test to compare the achievement of study between groups. The t -test result showed that the academic achievement in learning with group 1 was statistically significant than the learner in group 2. The effectiveness of the blended e-learning has been proved as the logistic regression analysis showed that the rate of the attendance in the cyber lecture functioned as indicator that enable to predict the acceptance.

The purpose of this study was to redefine and validate the motivational self-concept for child-care teachers. Based on related researches, items were remodified to be good enough to use for studying child-care teachers' motivational self-concept. Redefined items were analysed by factor analysis and validated by use of child-care teachers' professional recognition and their ego-resiliency. Researchers have garnered data from 321 child care teachers as convenience samples who are engaged in child care centers in Seoul and Kyunggi province by using questionnaire research methods. We have eliminated questions that are .40 below communality, questions by conducting exploratory factor analysis. As a result, 6 factors and 23 items were selected; 6 factors have indicated that it explained 77.12% of total variate motivational self-concept rating scale and ${\alpha}$ of Cronbach that of total items indicated acceptable level. After examining relevancy of child-care teachers' professional recognition and ego-resiliency to verify compliant feasibility of the motivational self-concept rating scale, the relation between motivational self-concept and professional recognition was .604(p<0.001) indicating significant static correlation and the relation between motivational self-concept and ego-resiliency was 4.456(p<0.01) indicating significant static correlation. Through this result, it is verified that motivational self-concept rating scale has compliant feasibility in professional recognition and ego-resiliency.

The current study examined the effects of teacher efficacy, and level of professionalism in the subject of interaction of teachers and children. The data collected in this study shows the following results. First, teachers over thirty years-old tend to show a higher level of teacher efficacy, level of professionalism and interaction of teachers and children compare to teachers who are under thirty. In categories, such as teacher efficacy and level of professionalism, accreditation experience caused significant difference. The group of teachers who had more than two times of accreditation experience show higher teacher efficacy than the group of teachers that had no experience, and the previous groups' level of professionalism was higher than the rest. Second, teacher efficacy has positive correlation in level of professional- ism and interaction of teachers and children. Level of professionalism of childcare teachers has positive correlation with interaction of teachers and children. Third, when examining the relative effect of socio-demographic variables, teacher efficacy and level of professionalism on interaction of teachers and children, mature teachers have more influence on verbal interaction of teachers and children; the teachers who have longer career have more influence on behavioral interaction of teachers and children. By and large, teachers who are older and have higher teacher efficacy and level of professionalism gain more influence on overall interaction of teachers and children.

The purpose of this study was to investigate and compare the effects of aerobic and complex exercise on body composition and blood lipids in the middle-aged women. Sixteen women whose ages ranged in 40 to 50 years were included in the sample of the study. The sample was divided into two groups: (a) aerobic exercise group (n = 8) and (b) combined exercise training group (n = 8). The aerobic exercise program consisted of bicycle ergometer, stepper, and treadmill, whereas; the combined exercise program was designed to improve muscular strength and aerobic capacity. Both programs took place 4 times a week for 12 weeks with the gradual increase of intensity (HRmax 60% 75% and 1 RM 60% 80%). Data were analyzed by nonparametric methods for pre-post within group mean differences (Wilcoxon signed rank test) and for between group mean differences (Wilcoxon rank sum test). Results indicated that there were statistically significant differences in BMI, body fat mass, and triglyceride within the sample of combined exercise; whereas, no significance existed in any variables within the aerobic exercise group. Results also revealed that statistical significance did exist in body fat mass between the combined and aerobic exercise group. These results implies that the combined exercise may be superior to aerobic only excercise for the body composition and blood lipid of the middle-aged women.
