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.

Objectives; This study was carried out to investigate the motor activity, glucose transport and metabolism of Jiaweizhengqi-tang(JKT) in rat small intestine. Methods ; The motor activity of the rat small intestine has been investigated by means of measuring barium sulfate passage degrees. Transport and metabolism of glucose were studied in everted sac of rat small intestine with incubation under several conditions. Results; Atropine treatment significantly delayed barium sulfate transit, and JKT pretreatment increased intestinal motor activity, but not significant. JKT administration showed renal toxicity in animal experiment, so clinical safety should settled to use commonly. The transport and metabolism of glucose were greater at jejunum than ileum. So, everted jejunum of rat were used to study the effect of JKT. When JKT were treated, the concentration of glucose were higher than untreated group. This result was thought to be influenced by the glucose in JKT. When 2, 4 dinitrophenol was treated, the transport and metabolism of glucose were decreased, but JKT treated together, the concentration of glucose in serosal solution increased. Conclusions; The transport and metabolism of glucose were influenced by the glucose in JKT. And the effects of JKT were still unidentified, but through continuous investigation, these effects of JKT should be identified.

Hot-water extract, Fr. 1, of Phellinus linteus mycelium was fractionated into Fr. 2, 3, 4, and 5 by the difference of solubility in ethanol. The polysaccharide fractions were studied for their immunostimulating activity on in vitro T-independent polyc1onal antibody response to trinitrophenyl-haptened SRBC (sheep red blood cell). The Fr. 4 with the highest immunostimulating activity was subjected to DEAE-cellulose ion exchange chromatography and gave five fractions, 4-I, II, III, IV, and V. The in vitro immunostimulating assay of the five fractions showed that 4-I and 4-III had a similar activity to that of LPS but the other fractions had low activity. By analyses of chemical composition and HPLC, all fractions obtained were found to be heteropolysaccharide-protein complex. The molecular weights ranged from 9, 000 to 15, 000. Sugar analyses showed that glucose, galactose, mannose, arabinose, and xylose were main component. Uronic acid and amino sugar were also detected in the fractions. It should be noted that the molecular weight (15, 000) of 4-III was very small and the structure of 4-III may be different from the known immunostimulating branched $\beta$-(1longrightarrow3)-glucan.

Horticultural therapy, as a kind of complementary alternative therapies using nature as a medium, is an intervention method that can be applied to various subjects by utilizing horticultural activities that anyone can enjoy as a leisure activity. This research defined the resilience of individuals as a personal characteristic, and examined differences in the intervention effect of horticultural activities depending on the level of resilience. The results obtained in this study can be utilized in planning a horticultural activity program and setting the purpose and goals of horticultural activity programs. The subjects of this study were divided into the high resilience experimental group (Group A), the low resilience experimental Group (Group C), the high resilience control group (Group B), and the low resilience control group (Group D). The experiment was conducted in the campus of G University from September to November 2017, and the experimental group participated in the program once per week, a total of 10 sessions. The Korean version of the Connor-Davidson Resilience Scale, autonomic nervous assessment, and the interpersonal relationship change scale were carried out as pre- and post-assessment. Statistical analysis was performed using a non-parametric test. Group A showed statistically significant positive changes in relaxation of physical tension and stability. In conclusion, those with high resilience showed the higher intervention effects of horticultural activities on physical relaxation and stability than those with low resilience. However, there were some possible limitations in this study. Since the number of subjects was small and subjects were limited to college students, it is impossible to generalize the results of this study. Therefore, it is necessary to conduct follow-up studies to address and overcome these limitations.

The ultimate goal of periodontal therapy is to promote the regeneration of lost periodontal tissue, there have been many attempts to develop a method to achieve this goal, hut none of them was completely successful. The purpose of this study is to evaluate the effects of Bio-Oss(R) on alkaline Phosphatase (ALP) activity in human fetal osteoblasts (hFOB1). The results of this study were as follows, in ALP Activity, 100 ${\mu}g/ml$ Bio-Oss(R) treated group showed significantly increased value than negative control group, but positive group($10^{-7}$ M dexamethasone treated group) showed the highest ALP activity at 3 day. In mineralization assay, numerous mineralized nodules were identified as darkly stained spots in 100${\mu}g/ml$ Bio-Oss(R) treated group than two control groups, whereas a small number of mineralized nodules were showed in the positive control. ALP may relate to the initial phase of bone nodule formation. On the basis of these results, this study showed Bio-Oss(R) is capable of accelerating new bone formation through hFOBl differentiation in vitro.
