This study examined the effectiveness of the Filial Therapy program for children with Separation Anxiety Disorder (SAD). Subjects were 8 mother-child dyads each in the experimental and comparison groups. Mann-Whitney U-test and the Wilcoxon Matched-Pairs Signed-Ranks Test were performed following the therapeutic program. After application of the Filial Therapy program, results showed that, compared to the control group, (1) parents of SAD children in the experimental group significantly increased their level of empathic interactions with their children. AND (2) the experimental group children significantly reduced level of somatic complaints, anxious/depressed, and social problems. Conclusions were that Filial Therapy is an effective program for improvement of parent-child relationship of SAD children but not for changing problem behavior of SAD children.

The main purpose of this study was to examine the effects of maternal materialism and parenting on materialism in adolescents. Moreover, the relative significance of maternal materialism and parenting materialism in adolescents was also explored. The study subjects were 199 (98 male, 101 female) high school students in Seoul and their mothers. The following are the major findings. 1) Maternal materialism was not related with male adolescents' materialism but was with female adolescents'. 2) Maternal support, and open communication were negatively related with female adolescents' materialism while maternal control, and permissiveness were positively related. On the other hand, only maternal control was positively related with male adolescents' materialism. 3) Stepwise regression analysis revealed that maternal support, followed by maternal materialism, was the most important variable affecting female adolescents'. However, for male adolescents, maternal control was the only one variable affecting their materialism.

Several coumarins isolated from Angelica sp. were described to show inhibitory effects against human platelet aggregation. The anti-thrombotic and anti-platelet potential was evaluated, in this paper, with the BuOH soluble fraction of Angelica dahurica root. The BuOH fraction was divided into five subfractions fr. A - E and tested in the mouse model of thrombosis. Survival was enhanced to 35% with fr. A or fr. E treated (500 mg/Kg, p.o.) group of mice compared with 5% survival of the control group. However, none of the 8 coumarin glycosides obtained from fr. A, at the conc. of 0.5 mg/ml, showed inhibitory effects against rat platelet aggregation induced by ADP or collagen.

A new method for quantitative determination of byakangelicin in Angelicae dahuricae Radix by high performance liquid chromatography was established. A reversed-phase system with a ${\mu}Bondapak$ $C_{18}$ column using THF : dioxane : MeOH : HAc : 5% $H_3PO_4$ : $H_2O$=72.5 : 62.5 : 25 : 10 : 1 : 329 as a mobile phase was developed. Byakangelicin together with ter-O-byakangelicin and oxypeucedanin methanolate, and isooxypeucedanin as an internal reference were detected at 350 nm and the analysis was successfully carried out within 30 min.

일반적으로 이차전지를 이용한 에너지 저장 시스템(ESS, Energy Storage System)과 전기 자동차(EV, Electric Vehicle)에 사용되는 전지(Battery)는 용량에 따라 직 병렬로 수십 개에서 수 만개의 배터리가 사용되기도 한다. 이러한 많은 배터리를 제어하고 관리하기 위해 필요한 것이 배터리 관리 시스템(BMS, Battery Management System)이다. 이러한 BMS는 ESS(Energy Storage System, 에너지저장시스템)의 핵심부품으로서, 관련업계에서는 새로운 기술 개발에 박차를 가하고 있다. 따라서 본 논문에서는 최근 개발되고 있는 AC 임피던스를 이용한 SOH 예측 기능을 검증할 수 있는 DSP(Digital Signal Processing) Platform 기반으로 Master-Slave 형태의 BMS를 개발하였으며, Master-Slave간에는 CAN 통신을 이용하여 제어성, 확장성을 용이하게 함으로써, 새로운 SOH 알고리즘 구현 및 성능 검증을 손 쉽게 구현할 수 있게 되었다.

본 논문에서는 운전자의 운전 패턴에 따른 연료 소비량을 감소하는 ECO_Driving에서 효율적으로 방법을 제안하였다. 이 ECO-Driving 시스템은 차량의 정확한 상태 정보를 바탕으로 운전 상태를 운전자에게 제공하여 경제운전 행동으로 배기가스 감축, 에너지절약을 유도하였다. 차량의 상태정보를 추출하기 위해서 차량 네트워크인 CAN 버스를 사용하였으며, 이를 하드웨어로 구현하였다. 효율적인 ECO_Driving을 위한 차량 데이터들을 추출하여 분석하였으며, 이들 데이터를 바탕으로 운전자에게 에코여부를 제공하는 프로그램을 구현하였다. 제한적인 실험이었지만 연비를 감소하는 것을 확인할 수 있었다.

Lately, minimize of the heat loss and fuel consumption when heating so that suggested ways to reduce carbon emissions as a measures to reduce for increase of carbon emission and find a way to apply highly insulated concrete as the measures. In this study, as a comparative experiments on heat conduction of concrete with lots of porous, thermal conductivity of concrete using foamed, polystyrene beads, lightweight aggregates, air-entraining agent and concrete using crushed stone measure and thermal conductivity of concrete with lots of porous compare and evaluate.
