This study was carried out to investigate the antioxidant activities of Dansam (S. miltiorrhiza). The Dansam (S. miltiorrhiza) was extracted with ethanol and methanol, and the extracts were fractionated with hexane, chloroform, ethyl acetate and butanol and water, in that order. The antioxidant activities of Dansam (S. miltiorrhiza) were determined by measuring the radical scavenging effects, using the 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) method. The electron donating ability was shown to be about 50% (IC50) at concentration of L-ascorbic acid, Dansam that reflected eliminatory effect by 50% were 9.48㎍/㎖, 8.28㎍/㎖ and 12.59㎍/㎖ respectively. According to the results of the above antioxidation experiments, those for the group with the added Dansam showed a decreased oxidation, but the antioxidation increased with time. With a storage temperature of 60℃ for 5 days, the acid value for the relative antioxidant activities were higher than in the Control group. The peroxide values for the relative antioxidant activities were also higher than in the Control group. The TBA values for the relative antioxidant activities were higher than in the Control group.

The purpose of this study was to develop the evaluation instrument for sensible aspects of housing environment. In terms of importance of sensibility which people persceive their housing environment, researches on the sensible environment has been done in several academic fields. However, evaluation tool for sensible aspects of housing environment has not existed until now. Therefore, there is a need to develop evaluation tool to measure the fit between dwelling environment and human sensibility. For this purpose, this study reviewed literatures and test results about ergonomics and human factors according to five senses. Based on keywords about five senses and housing environment, a checklist was developed.

본 연구는 볼링선수 (남자65, 여자70) 135명을 대상으로 Duda와 Nicholls(1989)가 개발한 스포츠성취목표지양검사지와 경쟁상태불안검사지(CSAI-2)를 이용하여 측정하였다. 이러한 목적을 달성하기 위하여 기술분석을 위한 성별에 따른 평균과 표준편차 및 t검증을 실시하였으며 변인간의 상관관계에 대한 기술분석을 실시하였다. 또한 성취목표, 경쟁불안이 운동수해에 미치는 영향을 알아보기 위하여 설정된 가설을 중심으로 다중회귀분석을 실시한 결과 다음과 같은 결론을 얻었다. (1) 남녀 볼링선수의 성취목표지향에 있어서 자아지향, 과제지향 모두 경쟁불안에 영향을 미치지 못하는은 것으로 나타났다. (2) 남녀 볼링선수의 성취목표지향에 있어서 남녀 모두 과제지향이 운동수행에 정적인 영향을 미치는 것으로 나타났다. (3) 경쟁불안과 운동수행결과에 있어서는 남자에 있어서 인지적, 신체적 불안 모두 운동 수행에 부적인 영향을 미치는 것으로 나타났으며 여자의 경우 는 경쟁불안이 운동수행결과에 영향을 미치지 못하는 것으로 나타났다. The purpose of this research is to analysis the correlation among achievement goal-orientation, competition state anxiety, and motor performance outcome in an object that consists of 135 bowler(male: 65, female:70) Achieving this purpose each bowler is test for achievement goal orientation, competition state anxiety, and motor performance outcome. Mean, standard deviation, and t-test of each gender are calculation and inspected for technical analysis, and Pearson'r are calculated for including the correlation between research variables, and multiple regression is performed to reveal relationship, and finally reached following conclusions. (1) Both of self-oriention and task-orientation do not affect competition state anxiety in view of achievement goal orientation for both gender of bowlers. (2) Task-orientation affects statically motor performance outcome in view of achievement goal orientation for both gender of bowlers. (3) Both of Cognitive and somatic anxiety affect negatively motor performance outcome for male, and competition state anxiety does not affect motor performance outcome for female in view of competition state anxiety and motor performance outcome.

The purpose of this study was to analyze the relationship between the sport achievement goal orientation and the anxiety, self-efficacy and motor performance in bowling. High school bowling players(male 105, female 110) who played more than two years were served as subjects. Pearson's correlation was computed for the relationship among factors and Analysis of Covariance(ANCOVA) was conducted for difference among factors by gender. The obtained conclusions were as follows 1. The task orientation had a on self efficacy and ego orientation had a positive effect on state self-confidence. 2. The state self-confidence had a positive effect on self-efficacy. 3. The cognitive state anxiety had a negative effect, whereas the self-efficacy had a positive effect on the bowling performance outcome.

Background: Confrontational naming test is useful in evaluating the language function. It reveals memory and cognitive processing dysfunctions in many neurologic diseases including dementia. Although the Korean version of the Boston Naming Test (K-BNT) has been a popular and useful test, it takes much time and effort in dementia patients of moderate to severe stage of disease or in elderly individual with low educational level. So we developed the Korean Naming Test (KNT). Methods: KNT consists of relatively easy 40 items. Each item was familar materials around us and simplified figures with black thick line. Ninety two of probable Alzheimer's patients received the Korean version of Mini-Mental State Examination (K-MMSE), the Korean version of expanded Clinical Dementia Rating Scale (CDR), K-BNT and KNT. We tested reliability and validity of KNT and also evaluated scores of the KNT along with CDR. Results: The KNT correlated with K-BNT [0.75(p;0.01)], CDR [-0.49(p;0.01)], K-MMSE [0.55(p;0.01)]. The internal consistency was 0.91 (Cronbach's alpha). The KNT score decreased as the disease progressed. Conclusions: The KNT is a brief and good test for evaluating language function of moderate to severe dementia patients with low educational level. Also it is sensitive to mild stage of disease and has a excellent reliability and validity.

Object: To compare pregnancy outcome between term pregnancy and postterm pregnancy. Method: A clinical observation has been made on 60 cases of postterm pregnancies out of 64 cases delivered at the Dept. of Obstetrics & Gynecology, Soonchunhyang University from January 1, 1997 to May 31, 2002. 100 cases of full term deliveries of 37 to 42 gestational weeks conducted in same period were used as the control group for this study. We analyzed their cesarean section rate, fetal weight, placental weight, meconium stain, perinatal morbidity. The statistical significance was defined as P<0.05. Result: The following results were obtained 1. The incidence of postterm pregnancy was 1.34%. 2. The cesarean delivery rate in postterm group(51.7%) was significantly higher than control group(26%). 3. The incidence of large fetus (weight over 4,000gm) in the postterm group(21.7%) was higher than control group(2%). 4. The weight of placenta was 757g and 706g in the postterm group and control group respectively. 5. 1, 5 minute Apgar score lower in the postterm group than control group. Conclusion : To decrease perinatal morbidity and cesarean rate at 42 or more weeks gestation, appropriate labor induction and twice weekly biophysical profile and USF(AI, Doppler) may be indicated.

Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.
