Background and Objectives ; This experimental study was conducted to evaluate an anti-stress effect of Gamisachi-tang(加味四七湯) on mice immobilized by stress. Methods : The experimental animals were immobilized by stress for 15 minutes, and administered 9mg/20g or 18mg/20g of Gamisachi-tang(加味四七湯) extract for seven days before they got stressed. The serotonin contents in the frontal cortex, hypothalamus, corpus striatum, hippocampus were measured by HPLC method in rat brain. Results : In frontal cortex, serotonin contents significantly decreased in both sample A and B group compared to the controlled group. In the hypothalamus, serotonin contents increased in both sample A and B group compared to the controlled group. In the corpus striatum, serotonin contents significantly increased in both sample A and B group compared to the controlled group. In the hippocamous, serotonin contents significantly increased in both sample A and B group compared to the controlled group. Conclusions : According to the above results, Gamisachi-tang(加味四七湯) had a significant impact on the changes in serotonin contents, which occurred in a separated part of mouse brain caused by stress.

The present study examined the effects of parent-education administered during divorce procedure on the perception of parent-education programs. The subjects were 60 couples who were in divorce procedure at the Seoul Family Court and had children under 20 Subjects were divided into three groups of 20 couples each: a control group, and experimental group 1 and experimental group 2 that were homogeneous in demographical and legal backgrounds. Experimental group 1 was shown pamphlets and videos on the role of divorced parents, and experimental group 2 was shown pamphlets and videos on the role of divorced parents as well as given explanations about the contents of the pamphlets and videos. No treatment was applied to the control group. According to the results of the experiment, the two experimental groups showed improvement in their perception of the necessity for parent-education programs. Demand for the number of sessions and hours, and the effect was higher in experimental group 2 than in experimental group 1. With regard to the necessity of parent-education programs, experimental group 2 was positive particularly to mandatory injunction, the payment of education fees and expectation of helpfulness. All three groups expected that parent-education programs would be helpful.

본 연구는 사용자의 감성을 효율적으로 유도하는 실시간 감성 이미지 콘텐츠 플레이어를 제안한다. 감성 이미지 콘텐츠 플레이어는 실시간으로 이미지 콘텐츠의 명도, 채도에 변화를 줌으로써 사용자의 감성에 따라 효율적으로 감성 유도가 가능하도록 설계하였다. 감성인식 부분은 자율신경계 기반의 맥파, 피부온도, 피부저항의 생체신호를 활용하였다. 사용된 감성 콘텐츠 이미지는 국제적 정서체계(IAPS)에서 분류된 9가지 감성영역의 이미지를 적용하였다. 실험결과로 감성 이미지 콘텐츠 플레이어를 통해 이미지의 감성 상태에 맞는 사용자의 감성이 10% 더 정확하게 유도되었다. 감성 콘텐츠 플레이어는 실시간으로 감성 반영을 통해 사용자와 콘텐츠간의 감성적 교감을 증대시킬 것으로 기대된다.

Objectives : This study aimed to evaluate the anti-stress effects of Guibi-tang and Yisiungyojae-dan on the contents of monoamines in the regional brain of mice immobilized stress. Methods : The experimental animals were immobilized in stress cylinder(height: 15cm, diameter: 3cm) for 15 minutes, and administered of Guibi-tang(6.0mg/10g) and Yishingyojae-dan(9.3mg/10g) water extracts for 7 days before stress. The monoamines contents were measured by HPLC method in various part(frontal cortex, hypothalamus, corpus striatum and hippocampus) of mice brain. Results: 1. In frontal cortex, the contents of norepinephrine were decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. 2. In hypothalamus, the contents of norepinephrine were decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. 3. In corpus striatum, the contents of dopamine were decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. 4. In hippocampus, the contents of serotonin decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. Conclusions: This study shows that Guibitang and Yishingyojae-don are significantly effective on reducing and preventing stress in mice. In addition, Yishingyojae-dan is more clear effective than Guibi-tang on the monoamines change in the mice brain.

The result of an experimental study on the mechanical properties and durability of polypropylene fiber reinforced concrete are presented in this paper. This study has been performed to obtain the properties of PFRC such as strength, toughness and durability. The test variables are fiber content, fiber types, W/C ratio. PFRC shows the highest strength when the polypropylene fiber contents were increased to 2.0 vol.%. Also, freeze-thaw resistance and carbonation were somewhat more improved than plain concrete.

An experimental study on the behavior of Steel Fiber Reinforced Concrete Columns under eccentric compression are presented. Forth-one columns were tested; the variables were column type, eccentricity of load, fiber contents, and longitudinal reinforcement ratio. The column size was $250\times160$ mm in cross section with an effective length of 1150 mm. Eccentricity of load was varied in the range from 1/6 to 1/2 times the column depth. This paper is to provides a framework for basic understanding of the steel fiber concrete columns.

This study was devised to observe the nutritional effect by feeding of rice diet supplemented with Ginseng powder in Albino rats. The male albino rats (84 heads), weghing about 56g, were used for the experimental animals. They were divided into six diet groups; which were the 6.4% protein diet, the 12.8% protein diet and the 17.9% protein diet as the control and each control diet was supplemented with 3% of Korean Ginseng powder as experimental diet. These diet groups were again divided into 2 groups according to the feeding terms, 3 weeks and 6 weeks. The animals were sacrificed after feeding the coresponding diet for 3 weeks and 6 weeks and the liver, heart, kidney, intestine and serum were collected as samples for analysis. The growth rate, efficiencies of protein and food, lipid, cholesterol and nitrogen in the samples were determined. The results obtained are summerized as follows; 1. The growth rate were improved by feeding of the 13% and the 18% protein diet supplemented with 3% ginseng powder than the coresponding control diet group, although the same results were not observed in the 6.8% protein diet groups. 2. The consumptions of the food and the protein in each dietary group were similar to each other. 3. The efficiencies of the food and the protein were improved by feeding of the 13% and the 18% protein diet supplemented with the ginseng powder than each control diet group. 4. The lipid contents in the liver of each expperimental diet group, in the feeding for 3 weeks, were shown the tendency to increase slightly, compared with the coresponding control group, whereas in the feeding group for 6 weeks, the contents were shown rater the decreasing tendency. 5. The total cholesterol contents in the liver of each experimental diet group, in the feeding group for 3 weeks, were maintained slightly higher level than the coresponding control group, whereas in the feeding group for 6 weeks, the contents were shown similar levels. 6. The total cholesterol contents in the heart were maintained with similar level in each diet group and each feeding term.

본 연구는 증강현실 콘텐츠 기반 수업이 학업성취, 학습흥미, 몰입에 미치는 효과를 알아보기 위해 수행되었다. 연구대상은 초등학교 6학년 5개 반 142명을 선정하였으며, 이중 3개 학급(86명)은 증강현실 수업을, 2개 학급(56명)은 교과서 중심의 일반 수업을 각각 2주간 처치하였다. 본 연구를 통하여 얻은 결과는 첫째, 학업성취에 있어서 증강현실 수업은 교과서 중심수업보다 더 효과적이었다. 둘째, 일반적 학습흥미에 있어서는 두 집단 간 유의한 차이가 없었으나, 수업자체에 대한 흥미에 있어서는 증강현실 수업 집단이보다 높은 흥미를 나타냈다. 셋째, 학습몰입에 있어서 증강현실 수업 집단은 교과서 중심 수업 집단보다 더 높은 수준의 몰입을 보였다. 본 연구가 실제 교실상황에서 정규교육과정의 일환으로 수행되었다는 점을 고려해 볼 때, 이러한 연구결과는 증강현실 콘텐츠 기반 수업이 기존의 교과서 중심 수업과 같은 전통적 수업을 보완할 수 있는 대안적 수업방법임을 시사한다.

도시하수 슬러지를 경작지에 투입하여 상추를 재배하였을때 그 양분으로서의 효과와 식물체 내의 중금속 축적을 조사하였다. 토양에 질소함량을 기준으로 6개의 처리구로 나누어 슬러지를 투입하여 상추를 재배한 결과는 다음과 같다.질소를 요소로 주입한 대조구에서 슬러지 처리구보다 잎과 뿌리의 길이도 길고 무게도 무거웠다. 슬러지로 처리한 구에서는 슬러지의 투입량이 많아질수록 잎과 뿌리의 길이도 길었고 무게도 무거웠다. 식물체내의 N, K, Ca, Mg는 처리간 차이가 없었고 P의 양은 처리간 차이가 있었다. 상추의 Zn 함량은 슬러지 200%처리구에서 65.8 mg/kg으로 다른 처리구보다는 높았다. 상추의 Zn, Mn, Cd의 축적량은 근채인 알타리 무에 비하여 높았으며, 근채의 잎 부분, 뿌리 부분의 순으로 축적량이 낮았다. 그러나 상추의 Zn, Mn, Cu, Cd 의 축적량도 시중 채소류의 자연 함유량 이내 이었다.
