Background and aims : The clinical syndrome unstable angina pectoris that encompasses a variety of symptoms and clincal presentations of transient episode of myocardial ischemia, was devided to several subgroups. Also, it has variable pathophysiologic factors to cause myocardial ischemia. According to clincal presentation, coronary angiographic finding and prognostic factor, the result of unstable angina pectoris is variable. In fact, there were a few data reported on the prognosis of wide spectrum of patients with unstable angina. However, the precise risk of subgroups according to classitication has not been established because it was difficult to compare between studies. We classified unstable angina pectoris by clinical nature of chest pain, and performed to establish and compare the clinical presentations, coronary angiographic findings, treatement and prognosis of patients with unstable angina within subgroups of classification. Methods : Retrospenctive data for 164 unstable angina pectoris patients admitted to the Internal Cardiology Division of Soon Chun Hyang University Hospital from May 1996 to July 1999 was analyzed. The patients were classified into one of the following categories: Class I, new onset of severe angina; Class II, acceleration of previous chronic stable angina; Class III, angina at rest. Clinical presentations, echocardiographic findings, coronary angiographic findings, treatment and prognosis were compared. Results : From the total 164 patients, the subjects of classes were as follows : Class I, 46 cases (28.1%); Class II, 74 cases (45.1%); Class III, 44 cases (26.8%). In view of age distribution, the 7th decade had the highest incidence, and then, 6th, 8th decades were followed. There was no baseline differences among the 3 classes with respect to gender, number of risk factors. Significantly, class II showed more severe findings in abnormal Q wave 15 cases (20.8%), total occclusive lesion 10 cases (20.8%) and three vessel coronary disease 11 cases (22.9%) than other classes. The change of ST segment was significantly apparent (p<0.02) among class I 28 cases (60.8%), class III 26 cases (59.0%), comparing with class II 30 cases (40.5%). Class III had the higher incidence of one vessel coronary artery disease than class I and III. The heparin treatment was performed in 99 cases (60.1%). The incidence of nonfatal myocardial infarction was much more in class I and III, each 4 cases (8.7%, 9.8%) than in class II 1 cases (1.4%). In-Hospital death was occurred in class I and II, each 1 case. Conclusion : The patients with the acclerated angina from chronic stable angina had more severe coronary artery disease than other classes, but they had better in-hospital prognosis.

It is very important to analyse drivers' visual behavior because visual information accounts for more than 90 percent of information for driving. There is a research that adjustment factor a tunnel is 0.95 and for a continuous tunnel is 0.09. The reason is that a vehicle slowed down for visual trouble in the tunnel section of highway. This problem usually happens but there has never been studied of human factor which is operated as causes. Therefore the importance of researches on stable driving, smooth travel and coping with traffic safety is increasing day by day. In this regard, this study has an eye to visual aspect among things which influence drives' activity.

연구목적 : 위스콘신 카드분류 검사가 정신분열병의 취약지표를 측정하는 도구로 이용될 수 있는지를 알아보기 위한 것이다. 방 법 : 중고등학교 재학생인 정신분열병 환자의 자녀 28명과 부모중 한 명이 알코올 의존증으로 정신과적 치료를 받고 있는 환자의 자녀 18명, 그리고 정신과학적으로 건강한 부모의 자녀 41명을 대상으로 위스콘신 카드분류 검사를 시행하여 세 군간에 그 결과를 서로 비교하였다. 결 과 : 위스콘신 카드분류 검사에서 세 군간에 총 시행 횟수, 총 정답반응 퍼센트, 총 오답반응 퍼센트, 보속반응 퍼센트, 보속 오답반응 퍼센트, 비보속 오답반응 퍼센트, 개념수준 반응 퍼센트, 완성한 범주 수, 첫 범주를 완성하기까지의 시행 횟수, 한 분류범주를 지속하지 못한 횟수, 그리고 학습 효율성 등과 같은 모든 변인에서 유의한 차이가 없었다. 정상 대조군의 하위 10%에 해당되는 총 정답반응 퍼센트 점수를 절단점으로 삼아 세 군에서 그보다 낮은 점수를 얻은 피검자들의 숫자를 확인한 결과 세 군간에 유의한 차이를 발견할 수 없었다. 결 론 : 본 연구 결과는 위스콘신 카드분류 검사에 의해 정신분열병의 유전적 취약지표를 찾아낼 수 없다는 가능성을 강하게 시사한다. In order to evaluate whether Wisconsin Card Sorting Test(WCST) could be used to detect the vulnerability markers of schizophrenia, three groups such as offsprings of schizophrenic patients(n=28), offsprings of alcoholic patients(n=18), and offsprings of psychiatrically normal persons(n=41) were examined for their concept formation and abstract thinking by means of WCST. The results were as follows ; 1) No significant differences were noted in all variables of the WCST such as number of total administered trials, total correct response %, total error response %, perseverative response %, perseverative error response %, nonperseverative error response %, conceptual level response %, number of completed category, number of trials to complete lst category, number of failure to maintain a set, and learning to learn among three groups. 2) There was no difference in the number of cases with extreme low WCST total correct % of lower 10% of the normal controls among three groups. These results suggest that WCST could be an ineffective instrument for using to detect the vulnerability markers of schizophrenia.

현재까지 국내에 개발된 팥의 이용성 증진을 위해 다양한 종피색의 팥 품종에 대해 앙금을 제조하여 품질 특성을 비교ㆍ분석하였다. 팥 품종별 수분함량은 8.2∼11.1 g/100 g, 조단백질은 15.4∼20.6 g/100 g, 조회분은 3.3∼3.6 g/100 g을 나타내었으며, 칼륨은 칠보팥(CB)과 홍언팥(HE)이 각각 875.1 및 873.1 ㎎/100 g으로, 칼슘은 중부팥(JB)과 금실팥(KS)이 각각 73.6 및 73.2 ㎎/100 g으로, 마그네슘은 연금팥(YK)이 131.4 ㎎/100 g으로 높은 함량을 보였다. 앙금 수율은 습물중은 188.3∼204.7%, 건물중은 62.1∼66.0%의 범위로 유의적인 차이를 보이지 않았다. 앙금의 명도는 종피색이 밝은 연금팥(YK)과 금실팥(KS)이 각각 67.0 및 68.0으로 가장 높은 값을 보였으며, 종피색이 검정색인 칠보팥(CB)이 54.0으로 가장 어두운 것으로 나타났다. 적색도(a-value)와 황색도(b-value)는 연금팥(YK)이 각각 6.6 및 12.8로 가장 높은 값을 보였고 칠보팥(CB)이 각각 3.8 및 5.9로 가장 낮았다. 앙금의 평균입자직경은 중원팥이 121.10 ㎛로 가장 크게 나타났고 중부팥이 100.80 ㎛로 가장 작은 값을 나타냈으며, 입도분포는 전체적으로 유의적인 차이를 보이지 않았다. 앙금의 입자는 타원형의 모양을 가지고 있었으며, 세포막과 단백질이 둘러싸서 표면이 거칠게 나타났다. 품종별 팥 앙금의 수분결합력 및 용해도는 유의적인 차이를 나타내지 않았다. 팥 앙금의 호화점도특성 중 최고점도, 최저점도, 최종점도 및 치반점도는 중부팥(JB)이 각각 3.79, 3.75, 7.33 및 3.54 RVU로 가장 높은 값을 나타났고 칠보팥(CB)이 1.21, 1.17, 2.46 및 1.25 RVU로 가장 낮게 나타났다. 이상의 결과를 볼 때 식품가공에서 팥 앙금의 선택은 관능적으로 색에 가장 많은 영향을 미치므로 생산하고자 하는 제품의 특성을 고려하여 팥 앙금을 사용하는 것이 바람직할 것으로 생각된다. We evaluated the quality characteristics of adzuki bean sediment according to variety. The moisture, crude protein, and crude ash contents of the various adzuki bean varieties were 8.2~11.1, 15.4~20.6 and 3.3~3.6 g/100 g, respectively. The potassium contents of Chilbo-pat (CB) and Hongeon-pat (HE) were 875.1 and 873.1 ㎎/100 g, respectively. The calcium contents of Jungbu-pat (JB) and Kumsil-pat (KS) were 73.6 and 73.2 ㎎/100 g, respectively. A high level of magnesium (131.4 ㎎/100 g) was found in Yeonkeum-pat (YK). The yields of adzuki bean sediment according to variety were no different either wet (188.3~204.7%) or dry (62.1~66.0%). The L-values on sediment of YK and KS were 67.0 and 68.0, respectively; however, the CB L-value was low at 54.0. A high level of a- (6.6) and b-value (12.8) was found in YK; however, the values for CB were much lower at 3.8 and 5.9, respectively. There was no difference in particle-size distribution, water binding capacity, and solubility of adzuki bean sediment according to variety. High levels of peak (3.79 RVU), trough (3.75 RVU), final (7.33 RVU), and setback viscosity (3.54 RVU) were found in JB. The sensory properties of products in food processing are important, and the variety of adzuki bean sediment should be chosen depending on desired product characteristics.

交通特性을 考慮한 新大衆交通手段 導入 方案에 관한 硏究 : 大田市를 中心으로 In the Daejeon Metropolitan City

金明洙,延基錫,全燦鎔 한밭대학교 2003 한밭대학교 논문집 Vol.20 No.-

The existing bus system provides low-cost convenient transportation for the citizens of Daejeon but it is now faced with many problems including poor services such as irregular arrival and departure, uncomfortable seating and . lack of safety, excessive competition among bus companies, difficulties in route alignment and environmental pollution by waste gas. This calls for the introduction of a new, innovative public-transportation system that best suits the image of Daejeon as a city of advanced science and the country's 2nd administrative capital. Ideally, a subway system is the best solution to meet the future transportation needs of the City of Daejeon whose population is near 2 million. With respect to subway line layout, it is important to plan Line 2 as a ring line and build Line 3 in a direction to intersect Line 1. Nothing else but a subway system is considered as the most desirable transportation means for the future. Construction of more subway lines is essential in order to solve the city's traffic problems and guarantee the future of the City of Daejeon.
