승용차 환산계수는 도로의 서비스 수준 및 용량 분석 등에 활용되는 자료이다. 본 연구에서는 개별차량자료를 활용 하여 차로수별로 국토교통부에서 구분하고 있는 12가지 차종에 대하여 승용차 환산계수를 산출하였다. 산출결과 차종 의 등급이 높을수록, 차로수가 많을수록, 주말일수록 승용차 환산계수의 값이 큰 것으로 나타났다. 승용차 환산계수를 활용하여 중차량 보정계수를 산출하였으며, 4, 6차로에서는 도로용량편람에서 제시한 결과와 비교했을 때 상대적으로 그 값이 작은 것으로 나타났다. 또한 차로수별로 중차량 비율에 따른 평균 승용차 환산계수 변화 모형을 추정하였으며, 2차로에서 PCE에 미치는 중차량의 영향이 가장 큰 것으로 나타났다. 이러한 연구결과는 다차로에서 중차량의 영향이 적고 주말의 통행은 상대적으로 업무통행 차량이 적기 때문으로 판단된다. PCE(Passenger Car Equivalents) is used to analysis of road capacity and LOS(Level of Service). In this study calculates PCE by number of lane and 12 vehicle type by MOLIT(Minister of Land, Infra Structure and Transport) using individual vehicle data. The results of the calculation, PCEs are increased when high vehicle classification level, many number of lanes and weekend. Heavy vehicle factors are smaller than KHCM on 4, 6 lane. Also, In this study estimates of PCE variation model by heavy vehicle percentage. Impact of Heavy vehicles on PCEs is the most sensitive on 2 lane. The results of the study, heavy vehicles low impact on PCE on multi-lane and business trips are a little in weekend.
BARRIERS TO COLLABORATING ACTIVITIES AMONG POLICY ACTORS IN INDUSTRY-ACADEMIA COLLABORATION POLICIES
김태운 한국행정학회 2010 International Review of Public Administration Vol.15 No.1
This paper explores barriers to collaboration among policy actors in the policy deliverysystem, focusing on industry-academia collaboration (IAC) policies in South Korea. At first,this paper shows that since individual actors in firms and universities are used to operating within the different organizational contexts of the norms, goals, and values that shape their practices, the individual actors exhibit different behaviors in collaboration. The individuals tend to fit their behaviors to their organizational context rather than to a policy context. In addition, the policy delivery system of the programs is characterized by a university-oriented mode in which universities exercise considerable power. Thus, in many cases, firms do not have legitimate roles in operating the programs. Due to these problems, in the IAC programs, many barriers to collaboration between policy actors with different organizational cultures occur.
12주간의 Circuit Weight training이 비만여고생의 항산화 작용에 미치는 영향
김태운,한재웅 대한비만학회 2000 The Korean journal of obesity Vol.9 No.2
The purpose of this study was to determine the effects of Circuit Weight Training (CWT) on antioxidant activity in obese high school girls. The 22 subjects were used in 2 groups by the BMI classification : obese group of 11(BMI : ≥ 27 kg/㎡) and normal group of 11 (BMI : 19 ~ 24 kg/㎡). They were under the same exercise conditions to perform the Circuit Weight Training with 40 ~ 45% intensity of 1RM, for 50 mins/day, 3 times/week during 12 weeks. Before and after training , 10 mL blood was extracted from antecubital vein of each subject for the purpose of analyzing its effects on antioxidant activity. The variables tested for this study were H_2O_2, OH, GSH, GSSG, MDA and Uric acid. The conclusions of this study are as follows : 1) In the comparison between groups, there are no significant differences of means of variables tested for antioxidant activity between before and after training. 2) In the comparison within group, the means of uric acid and GSH have significantly decreased by training but the OH scavenging activity mean has significantly increased in obese group. Also, in normal group, the GSH and uric acid mean have significantly decreased but, the means of·OH scavenging activity and GSSG have significantly increased. 3) The means of·OH scavenging activity, GSH and uric acid in 2 groups were all significantly different.
