The District Unit Planning(DUP) system, which was introduced in the revised Urban Planning Law in 2000, is a policy instrument for specific planning in a special area in urban setting. The main purpose of this study is to find better DUP in Man-duk in Busan. Through comparing two plans ; One is planned low buildings in Man-duk, the other is planned high buildings in the same; in Man-duk. To compare these plans, the study suggested to consider the several criteria and landscape-simulations. By comparing two DUP in Man-duk, the second plan was better for residents than the frist. DUP system is concerned with improving the urban spatial quality, but we have recognised that DUP system has some problems. There are many various types in urban area which is needed DUP system. Finally, based on this study, urban areas need the flexible application of DUP for each type and is considered the correlations of area-specific and goal-specific features. 현행 지구 단위계획의 목적은 용도지역제의 의 문제점과 한계 를 극복하고 당해 지역 토지의 효율적 이용과 주민의 안정된 주거환경 도모는 물론 인접지역과 조화를 창출하자는데 있다. 지역이 지구단위계획에 의해서 개발되면, 토지의 입체적 이용, 지구 내 기능의 적정 배분, 도시설계 상 융통성 부여, 그리고 지구 간 조화의 도모 등에 있어 무리와 경직성이 최소화 될 수 있다. 이로부터 토지의 효율적 이용에 의한 난개발 방지, 경관보전, 그리고 지역전체의 안정된 공간구성의 극 대효과를 얻을 수 있다. 최근 들어 많은 지역에서 지구단위계획의 수립이 요구되고 있으며 그 대상과 범위는 상이하다. 그러나 지구단위계획의 운용실태를 살펴보면 차별적 계획목표의 부재와 천편 일률적인 계획요소의 적용으로 많은 문제점 이 나타나고 있다- 따라서 본 연구는 하나의 연구 사례대상 지역을 선정하고 이 지역에 어떤 형태의 주거단지가 개발되는 것이 지역 전체의 조화를 창출할 것인지 를 파악코자 한다. 또한 주어진 대상지의 내적 조건상 어떤 유형의 개발이 효율적 토지이용의 최선인가 를 밝히고자 한다. 이 과정상 바람직한 지구 단위계획의 방향도 모색될 것이다.

Objects : Several lines of possibilites have been oroposed about the etiology of bipolar attective disorder in biological, genetic and psychosocial aspect. The purpose of this study is to inspect the etiology of bipolar affective disorder in biological aspect by measuring the changes of serum inositol-1-phosphatase activity and investing a causal relationship between clinical symptoms and serum inositol-1-phosphatase activities in patients with bipolar affective disorder. Methods : The subjects were 18 inpatients who met DSM-IV diagnostic criteria for bipolar I affective disorder, manic episode and 15 normal controls. Inositol-1-phosphatase activities were measured in serum by using spectrophotometer. Clinical symptoms of patients were assessed by YMRS at admission day and after 2 weeks lithium treatment. Results : 1) Inositol-1-phosphatase activities of the patients were increased to about 2 times as compared with those of normal controls. And the activity levels were decreased gradually to the normal at 14 days. 2) Young's Mania Rating Scale(YMRS) scores were decreased significantly by lithium treatment. 3) Statistical significance could not be found between the change of YMRS scores and the levels of inositol-1-phosphatase activity. Conclusion : In this study, statistical significance could not be found between clinical improvement and inositol-1-phosphatase activities, but the fact that lithium treatment improve the clinical manifestation shown by YMRS score changes, and reverse the increased inositol-1-phosphatase activities suggests the strong association between pathophysiology of bipolar affective disorders and inositide metabolism.

Abstract - Removable protective adhesives for automobiles were synthesized by the emulsion polymerization of monomers, such as n-butyl acrylate(BA), n-butyl methacrylate(BMA), acrylonitrile(AN), acrylic acid(AA) and 2-hydroxyethyl methacrylate(2-HEMA), in which AA and 2-HEMA were functional monomers. Emulsion polymerization was conducted with a semi-batch type reactor. Tensile strength, extension, peel strength, viscosity and solid content of the synthesized adhesives were measured. In addition, acid resistance, alkali resistance and smoke resistance were also examined. As a result, with 0,43 mol of BA, 0,57mol of AN and 0.14~0.21 mol of BMA, the tensile strength, extension and peel strength of the synthesized adhesives satisfied the standard of removable protective adhesives for automobiles.

Objectives: K^(+) channels play an important role in regulating cellular excitability. The aim of this study was to know whether or not inward rectifier K^(+) channel exists in colonic smooth muscle cells. Methods: Mouse colonic smooth muscle cells were isolated using collagenase, and then we recorded their membrane currents using a whole-cell patch clamp technique. Results: With 90 mM K^(+) in bath, hyperpolarization-induced inward currents from -120 mV to 20 mV with 400 ms duration at a holding potential of -10 mV showed rapid activation, inactivation and inward rectification. The inactivation showed single exponential time course. Reduction of external K^(+) to 60 mM decreased the amplitudes of the currents in whole test voltage range and shifted the reversal potential to more negative potential. The inactivation process and peak currents of hyperpolarization-induced inward currents were not affected by removing external Na^(+). External Ba^(+) blocked hyperpolarization-induced inward currents by dose-dependent manner and pure Ba^(+)-sensitive currents showed strong inward rectification. Cs^(+) also suppressed hyper- polarization-induced inward currents. Ba^(+) and Cs^(+)-induced inhibitiOn of hyperpolarization-induced inward currents was voltage-dependent, and the extent of inhibition increasing with membrane hyperpolarization. Conclusions: These results suggest that inward rectifier KU channels may exist in proximal colonic smooth muscle and may play an important role in regulating membrane potential.
