연구배경 : 국내 비만 여성을 대상으로 비용이 적게 들고 단순하면서도 보다 정확하게 체지방률을 추정할 수 있는 체지방률 추정식을 작성함으로써 쉽게 체지방률과 조절해야하는 지방의 양을 판단할 수 있도록 하고자 한다. 방법 : 이대목동병원 비만클리닉을 처음으로 내원한 19세 이상의 성인 여자 607명 중 체질량지수가 25 kg/㎡ 이상인 500명을 연구대상으로 하여 목, 가슴, 허리, 엉덩이, 대퇴, 하퇴, 발목, 상완, 전완, 손목의 10부위의 둘레와 생체전기저항분석법 (bioelectrical impedance analysis, BIA) 방식의 체성분 분석기를 이용하여 체지방률을 측정하였다. 체지방률 추정식을 구하기 위해 BIA에 의한 체지방률을 종속변수로 하고 , 신체 둘레 계측기 및 신장, 체중, 체질량지수, 연령을 독립변수로 하여 단계별 다중회귀분석 (multiple stepwise regression)을 시행하였다. 결과 : 신장과 체중, 연령, 체질량지수 및 신체 둘레 측정치 중 체지방률을 반영하는 지표는 체질량 지수, 전완둘레, 신장, 엉덩이 둘레, 하퇴둘레였고, 이 다섯가지 지표를 이용한 체지방률 추정식은 66.1%의 예측력과 2.86%의 측정 오차를 나타냈다 (R^2=0.661, SEE=2.86). 결론 : 비만한 성인 여성에서 신장과 체중, 연령 및 신체 둘레 계측치를 이용한 본 연구의 추정식은 체지방률(%)을 적은 오차범위로 비교적 정확하게 반영하였다. Background : This study was conducted to develop a regression equation that accurately estimates body fat percentage using relatively easy and inexpensive method in adult obese Korean women. Method : Data were collected among 500 obese Korean women visiting obesity clinic in Ewha woman's university Mokdong hospital, Seoul, Korea. Height, weight, and circumferences at ten body sites (neck, chest, waist, hip, thigh, calf, ankle, arm, forearm, wrist) were measured s well as total body bioelectrical impedance. Results : The full regression equation estimates body fat percentage included six variables : BMI, forearm circumference, height, hip circumference, thigh circumference. This equation accounted for 66.1% of the variance in body weight measured by bioelectrical impedance, and their standard error of estimate was 2.86%. Conclusion : For the obese Korean women in this study, circumference measurements provided a s relatively good estimation of body fat percentage.

Background : The authors attempted to introduce group program for improving interpersonal relationship and evaluate the effects of that program. Material and Methods : This program had been held twice a week for 8 weeks for children and parents training had been for times on the treatment and continued from 2001 to 2002. Twenty-five ADHD children in school age were selected as subjects from child psychiatric clinic of a general hospital in Seoul. Treatment outcomes were evaluated by comparing at pre- and post- treatment using the various rating scale. Result : According to the results of statistical analysis, paired t-test, the score of total self-concept including popularity was increased and family environment and parenting stress were improved significantly. These results suggest that this program is useful for its orginal goal. The parents evaluated also that children's total problem behaviors were decreased. Conclusion : These results suggest that the designed and performed group program in this study would be effective in facilitating ADHD children's emotional and interpersonal growth, and decreasing their parents stress. Finally they would have healthy interpersonal reationship.

In this paper, we focused on the implementation of e-learning system for training of power distribution operators in Power Company. And also this paper presents Web-based system for electric power quality analysis based on the LabVIEW approach to enhance streaming of live data and to facilitate the interaction on the PC platform The recent growth in the use of impactive nonlinear loads, electronic and medical devices with sensitiveness to power quality has caused many power quality problems and power supply-and-demand problem. Therefore, the proposed system can also support the solution tool for field operators in the various power quality problems.

Various transition metal carbonyl complexes catalyzed the carbonylation of p-xylylene dibromide to give p-phenylenediacetic acid in moderate yields in the presence of phase transfer agents such as crown ether and quaternary ammonium salt at atmospheric pressure of carbon monoxide. These metal complexes were less effective in the case of carbonylation of ortho- and meta-xylylene dibromides. On the other hand, p-tolylacetic acid was predominantly obtained when p-xylylene dichloride was applied to this two phase system. And also, meta-and para-xylylene dibromides reacted with carbon monoxide in the presence of palladium (0) complexes such as tetrakis(triphenylphosphine) palladium (0), and bis (1,2-diphenylphosphinoethane) palladium(0) under phase transfer catalyst to give selectively mono-carbonylated products in reasonable yields.

This paper presents a new approach to the design of cruise control system of a mobile robot with two drive wheel. The proposed control scheme uses a Gaussian function as a unit function in the fuzzy neural network, and back propagation algorithm to train the fuzzy neural network controller in the framework of the specialized learning architecture. It is proposed a learning controller consisting of two neural network-fuzzy based on independent reasoning and a connection net with fixed weights to simply the neural networks-fuzzy. The performance of the proposed controller is shown by performing the computer simulation for trajectory tracking of the speed and azimuth of a mobile robot driven by two independent wheels.

Rosin moiety-containing monomers were prepared by the reaction of abietic acid with 1,4-butanediol vinyl ether, ethylene glycol vinyl ether and diethylene glycol vinyl ether using diethyl azodicarboxylate as a catalyst. These new monomers were photo-polymerized to give thin films in the presence of a sulfonium salt containing long alkyl chain. The rate of photopolymerization and amount of cured polymer were determined using real-time infrared technique. The final conversion of double bond is achieved in less than 30sec.

The reduction of nitro and nitroso compounds using tetracarbonylhydridoferrate-formaldehyde under mild conditions (at room temperature and then 60℃ under CO) gives the corresponding N, N-dimethylation via N-methylation in good to excellent yields. The reaction mechanism via immonium salt is assumed.

This research proposed a model for the determination of optimal safety stock for multi-echelon inventory system. The criterion is to minimize expected anaual total cost safety stock of system under service level constraint. The results of numerical examples for three-echelon inventory system are analized and compared with Salameh and Schmidt's model. The heuristic method is presented to find an optimal-tending solution for total variable system cost per year. The numerical examples are illustrated for verification and validation purposes.

유럽단일시장의 형성과 공동사회정책의 가능성 연구

심상필,조홍식 서울대학교 국제지역원 1996 국제지역연구 Vol.5 No.2

유럽통합에 관한 학문적 논의에 있어 사회적 차원만큼 논쟁의 대상이 되는 부분도 드물다. 일부에서는 현재까지 진행되어온 사회적 차원의 발전을 주목하면서 앞으로도 이 분야의 통합이 순조롭게 진행되어 공동사회정책의 단계에 도달할 것이라고 평가한다. 그러나 다른 학자들은 유럽통합이 경제적인 단일시장의 형성을 주요 목료로 하고 있기 때문에 사회적이 ㄴ차원은 단지 경제통합을 동반하거나 정당화하는 부속물일 뿐이라는 시각을 보이고 있다. 이 논문은 1) 규범적 차원에서 각종 규칙의 생산과 2) 이들이 실질적으로 적용되는 과정까지를 포함하는 포괄적 의미의 정책을 구분함으로써 사회적 차원에 대한 다양하고 상반된 평가가 주는 혼동에서 탈피해 보려는 시도이다. 역사적으로 볼 때 사회적 차원은 1950년대의 로마조약에서 시작하여 특히 1970년대의 행동계획과 1989년의 사회헌장이 채택될 때까지 지속적으로 강화되어 왔다. 최근에 체결된 마스트리히트 조약은 이같이 생산된 규범적 사회정책을 실천하는데 필수적인 정책수단을 제공함으로써 유럽공동사회정책의 생성을 위한 기초를 마련해 주었다. 결국 유럽 특유의 사회경제모델에 바탕한 공동사회정책의 실현 가능성은 무엇보다 주요 회원국들의 집권세력분포와 성향에 좌우될 것이다. In the current academic debate on European integration, the social dimension represents one of the most controversial issues. In an incrementalist and somewhat optimistic perspective, many studies consider that european integration process has been covering various dimensions, from the formation of the customs union to the production of common policies, including the social dimension. ON the other hand, in a critical perspective, pessimists point out the fact that the integration process was mainly oriented to economic community building, avoiding any consideration of the social dimension. This article aims to clarify the confusion induced by the differences of view and introduces the distinction between the production of social norms and rules in the integration process and their implementation at both the European and national level. Historically, the social dimension has been present since the Rome Treaty of 1950's and reinforced since then, especially by the action plan of the 1970's the Social Charter of 1989. The Maastricht Treaty gave the European Union policy instruments necessary for the effective implementation and harmonization of social norms, opening the way to the emergence of the european common social policy. The contingency of this policy based upon the specificity of a european socio-economic model fundamentally depends on the distribution and the nature of governing political forces among main member- countries and their interaction in the context of enlargement.
