소집단 과학 탐구 활동에서의 학습자들의 적극적인 참여와 활발한 상호작용은 과학 학습의 효과를 결정하는 주요한 요인이라 할 수 있다. 소집단 내 구성원들 간의 상호작용을 촉진시키기 위하여 소집단 구성원들에게 역할을 부여할 수 있다. 본 연구에서는 중학생들의 과학 탐구 활동에서 역할 부여가 언어적 상호작용의 유형 변화와 양상의 변화에 미치는 영향을 분석하고자 하였다. 이를 위해 광역시 소재 2개 중학교 학생 172명을 대상으로 하였다. 역할을 부여한 소집단 18개, 역할을 부여하지 않은 소집단 15개를 분석하였다. 역할 부여에 따라 탐구 활동에서의 언어적 상호작용 유형의 변화는 크게 소외형과 참여형으로 구분하였다. 역할을 부여한 경우에 참여형이 소외형에 비해 더 높은 비중을 차지하였다. 언어적 상호작용의 양상은 인지적, 정의적 측면에서 역할을 부여하였을 때 차이가 크게 나타나지 않았다. 이를 바탕으로 역할 부여가 과학 탐구의 유형과 탐구 단계에 따라 언어적 상호작용에 어떠한 영향을 미치는가에 대한 추가적인 연구가 필요하다. 또한 소집단 구성과 역할 부여 방식에 대한 추가적인 연구도 요구된다.

본 연구의 목적은 소집단 활동에서 과학영재들의 의사소통 구조를 찾아보고, 이들의 의사소통 유형과 성취 수준의 관계를 알아보기 위한 것이다. 이를 위하여 과학영재들을 대상으로 5명을 한 단위로 하는 8개 소집단을 구성하고, 이들에게 지구의 밀도 구하기라는 주제로 토론식 수업을 적용하였다. Pajek과 UCINET 6.0을 활용하여 과학영재들의 대화로부터 의사소통 구조와 성취 수준을 분석하였다. 그 결과 상호작용 분산 정도에 따라 과학영재들의 의사소통 유형을 독점형과 공유형으로 분류할 수 있었다. 그리고 상호작용 밀도와 집중도에 따라 과학영재들의 의사소통 유형을 $D_H{\cdot}N_H$형, $D_H{\cdot}N_L$형, $D_L{\cdot}N_H$형, $D_L{\cdot}N_L$형으로 분류할 수 있었다. 과학영재들의 소집단 활동에서 문제 해결 성취 수준은 구성원 간 상호작용의 분산이 아니라 상호작용의 밀도와 연결망 집중도의 차에 의해 영향을 받는다는 것을 알 수 있었다. 그러므로 교사들은 소집단 활동을 활용하여 학생들을 지도할 때 문제 해결에 관련된 의사소통이 이루어지도록 지도할 필요가 있다.

This study was performed to investigate the influcence of mugwort on the duodenal ulcer induced by cysteamine administration in rats. Five groups of rats were fed each experimental diet containing 0%, 5%, 15%, 30% of mugwork powder for 10 weeks. Duodenal ulcer was induced by cysteamine injection (400mg/100g body weight) after 10 weeks of feeding experimental diets (C-0, C-5, C-15, C-30). Control animal that fed 0% mugwork powder added diet were injected saline (S-0) to compare with cysteamine injected groups. When the duodenal ulcer induced by cysteamine-HCI administration, all animals in the C-0 group formed erosion and perforating ulcer was found in 44% of animals. Higher the added mugwork ratio, more inhibited of the duodenal ulcer induced by cysteamine administration (C-5, C-15). But when the ratio of added mugwort is 30%, the inhibition effect disappeared (C-30). The alkaline phospatase activities were lower at the duodenal mucosa and small intestinal mucosa in the cysteamine treated groups(p<0.05). The acid phophatase activities were higher at the stomach, small intestine and large intestine of the cysteamine treated groups. But in mugwort added diet group, the changes of enzyme activites were lessended. The maltast activities were lower at the duodental mucosa and small intestinal mucosa of cysteamine treated groups. But in mugwort added diet group, maltase activites were recovered.

This research studies the role of IT (Information Technology) in improving productivity of a company through samll group activities. For this purpose, this research analyzed the samll group activities of the company as to how IT was employed bo improve business processes. Cases of small group activities that were conducted from January, 1996 to December, 1996 in a Korean company (name withdrawn) were analyzed. Eight out of eleven small group activities have been studied. They were examined as to the effect of IT in time and cost savings, reduction in manpower and so on. TQM is the activity of process improvement based on the existing processes in pursuit of satisfaction of customers' needs. This study analyzed how IT was used to solve the current problem in business processes. As a result of the case study, it is found that TQM activities with IT could reduce expenses significantly. More specifically, expenses have been cut down by 56% a year on average. By improving the business processes through the activities of TQM which used IT, companies could remove the unnecessary business processes and the duplicated business processes. In other words, with the use of IT in TQM activities, they could move closer to goals of the satisfaction of the customers' needs by reducing expenses and time. This study examined the role of IT from the point of view of business process improvement. Internally, IT has a positive impact on reducing expenses, processing time, manpower and so forth. Externally, it plays an important role of company's gaining competitive advantage through the satisfaction of customers and stakeholders. In conclusion, the proper use of IT will significantly increase the performance of a company.

Purpose: The purpose of this study was to evaluate effects of a cognitive improvement program on cognition, activities of daily living (ADL), depression, life satisfaction, and grasping power in small groups. Methods: A nonequivalent control group pretest-posttest design was used. Participants were 127 elders who were never diagnosed with dementia and could read (experimental: 61, control: 66). The program was consisted of 8 sessions to improve vocabulary and writing skills and fine motor skills. Each session was applied once a week for 8 weeks. A group was consisted of less than five members. Results: Cognition (t=3.82, p<.001), depression (t=-2.24, p=.027), life satisfaction (t=2.25, p=.027), and grasping power (Rt: t=2.44, p=.016, Lt: t=2.63, p=.010) except ADL (t=-0.49, p=.622) were significantly increased in the experimental group after the cognitive improvement program compared to the control group. Conclusion: This study indicates that the cognitive improvement program was effective to improve cognition, depression, life satisfaction and grasping power. Further study is needed in order to identify continuous effects of this cognitive improvement program.

This paper studied on the relationships between productivity and job satisfaction in small group activities. The researches were practiced with the same method which prof. Rao of Babson university et al.(1987) did on autonomous work groups in U.S.A.. The researcher divided companies of Korea and Japan into similar small groups such as high productive groups and low productive groups in each country and analyzed their degree of job satisfaction. According to the result, high productive groups indicated higher degree of job satisfaction than low productive groups. In the case of Korea, besides activating QC circle activity, it is also necessary to equalize the difficulty of the works, or to set up the pay system taken the difficulty of the works into consideration. In the case of Japan, it is important to encourage good human relationships and member's cooperation and unity.

The purpose of this study is to examine a theoretical framework for the interactions of learning in a small group setting of mathematical problem solving. Many researchers already have described the theoretical background for the small group settings in problem solving. However, most of the literatures merely have reported findings of achievement and rising of test scores. They ignored the observation of process taken during the small group work and have not determined how various psychological, social and academic effects are created. As results of the study, two types, mutual collaboration and asymmetric collaboration, of interactions are observed as the interactions of learning, which are conceived as the cores of authentic mathematical activities.

The purpose of this study is to examine the effects of small group inquiry skills on improving science process skills and attitudes toward science in elementary school science. The research questions of this study were as follows. First, effects of small group inquiry skills on improving science process skills in elementary school science. Second, effects of small group inquiry skills on improving attitudes toward science in elementary school science. The subjects of this study is two classes from 6th grade elementary classes in Busan. The experiment class practiced small group inquiry skills, while the control class practiced self inquiry. To verify the effect of the experiment, ANOVA was conducted. The main findings of this study are as follows. First, the small group inquiry skills gave a significant influence on increasing the science process skills, including the basic science process skills and the integrated science process skills, of students. Especially, among subordinate factors of science process skills between groups, it was effective to increase abilities of observing, reasoning, interpreting data, formulating hypothesis. It is necessary for teachers to make an effort to teach according to steps of the small group inquiry skills and to support inquiry activities, in order to increasing the science process skills. However, frequency of additional lessons have a little influence on increasing the science process skills. Second, there is meaningful change in the attitudes toward science for those who studied the small group inquiry skills. Also, they affected subordinate factors of the attitudes toward science, like the attitudes toward science inquiry, the happiness about science class. This study shows that the small group inquiry skills give a positive influence on the science process skills and attitudes toward science in elementary school science.
