The purpose of this study is to suggest optimum size of residents' bedrooms in nursing homes. Bedroom is an essential part of nursing homes because nursing home residents spend most of their times in bedrooms and occupy the largest part of facility area. Therefore it is necessary to set an adequate standard related to resident room area in nursing facilities, which have a great effect on planning longterm care facilities for the elderly. The body dimensions of elderly people and care givers have been collected from the previous study. Based on the body dimensions data, the behaviors of elderly as well as care givers have been analysed. The minimum areas-exclusive of toilets, closets, vestibules and so on - have been proposed from the results of the behavior analysis.

이 논문에서는 P₂O_(5)-ZnO-BaO계와 SiO₂-ZnO-B₂O₃계의 반사특성과 유전특성이 연구 되었다. P₂O_(5)-ZnO-BaO계의 반사율은 SiO₂-ZnO- B₂O₃계의 반사율보다 낮게 나타났고, TiO₂의 함유량이 증가할수록 반사율이 감소되었다. 또한 P₂O_(5)-ZnO-BaO계의 유전율은 SiO₂-ZnO-B₂O₃계의 유전율보다 높은 값을 보였고, TiO₂ 함유량이 증가함에 따라 두 계 모두 유전율이 증가되었다. 이 현상은 공간전하효과로 설명될 수 있다. 본 연구의 결과는 높은 반사율과 높은 절연파괴 강도가 요구되는 플라즈마 디스플레이(PDP)의 하판 유전체, 또는 플라즈마 현상을 응용하는 조명 및 광고용 기구의 반사 유전체로서 응용이 가능할 것으로 기대된다. In this paper, the reflectance and the dielectric characteristics for P₂O_(5)-ZnO-BaO system and SiO₂-ZnO-B₂O₃ system have been investigated as a function of contents of TiO₂. The reflectance was decreased with increasing the contents of TiO₂ contents, and the reflectance of P₂O_(5)-ZnO-BaO system was lower than that of SiO₂-ZnO-B₂O₃ system. The dielectric constant of P₂O_(5)-ZnO-BaO system was higher than SiO₂-ZnO-B₂O₃ system, and the dielectric constant in the both system was increased with increasing of TiO₂ contents. This could be explained as the space charge effects. These results are could be applied to the under plate dielectrics of PDP required high reflective ratio and breakdown strength.

As a result of rapid aging speed in our society, it is necessary to supply a lot of housing for older people in near future. When we think that high portion of residence in rental housing complex composed of small units is the elderly, the housing units in those apartments have to be designed for the physical, mental, social, and economical conditions of elderly people who lives in such a residential complex. Considering these living conditions of the elderly, this study proposes a remodeling prototype of a living unit for older people in rental housing complex. For the research of this topic, various characteristics of the elderly and the environmental requirements for them firstly have been analysed from the literature survey and the interviews with two residents living in a rental apartment. And the design considerations for each space of the housing unit such as entrance, living room, bed room, bath room, and so forth have been explored. Based on the design guidelines above, the remodeling plan of a housing unit for older people has been propose as a result of this study.

Abstract-In order to investigate the pharmacological properties of New Wonbang Woohwangchungsimwon Liquid (NSCL), effects of Wonbang Woohwangchungsimwon Liquid (SCL) and NSCL were compared. In isolated rat aorta, NSCL and SCL showed the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6 M) regardless to intact endothelium or denuded rings of the rat aorta. Furthermore, the presences of the inhibitor of NO synthase and guanylate cyclase did not affect the relaxing effect of NSCL and SCL. NSCL and SCL inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs), NSCL and SCL significantly decreased heart rate. NSCL and SCL, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, NSCL and SCL had no effects on parameters of action potential such as resting membrane potential, action potential amplitude, APD_90 and V_max at low doses, whereas inhibited the cardiac contractility at high doses. These results suggested that NSCL and SCL have weak cardiovascular effects with relaxation of blood vessels and decrease of heart rate, and that this effect is no significant differences between cardiovascular effects of two preparations.

본 논문에서는 웹 광고에서 웹사이트를 방문하려는 고객과 서버(예를 들어, 웹사이트 발행자들)간에 상호작용을 측정하기 위한 안전하고도 효율적인 측정 방법들에 관해 살펴보고자 한다. 대개의 웹 광고는 많은 고객들과 서버들 그리고 서버들에 의해 제공된 고객들의 수 에 관한 정보를 수집하는 감사 기관의 상호작용으로 이루어진다. 이때, 대부분의 서버들은 실제 제공되는 것보다는 훨씬 많은 수의 방문 정보를 감사기관에게 제시함으로서 보다 많은 광고 수익을 얻고자 한다. 이에 본 논문에서는 과장된 서버로부터의 방문기록을 막는 암호학적으로 안전한 몇 가지 측정 방법들을 소개하고자 한다. 아울러 이들 측정 방법들은 전반적인 통신 트래픽 이라든가 다른 부수적인 오버헤드가 부가되지 않을 만큼 효율적이어야 할 것이다. In this paper we study on secure and efficient metering schemes to measure the interaction between clients and servers(e.g. the web site publishers) on the web advertisements. In a representative scenario there are many clients and servers, and an audit agency should collect information about the number of clients that were served by each server. A typical server is motivated to claim that it served many more clients than it has actually served. We introduce some metering schemes which are cryptographically secure and prevent servers from inflating the count of their visits. At the same time the metering schemes should be efficient and do not add a considerable overhead to the different parties and to the overall communication traffic.

Abstract-In order to investigate the phamacological properties of New Wonbang Woohwangchungsimwon Pill (NSCH), effects of Wonbang Woohwangchungsimwon Pill (SCH) and NSCH were compared using various experimental models. In rat aorta, NSCH and SCH made the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6 M) regardless to endothelium containing or denuded rings of the rat aorta. Furthermore, the presence of the inhibitors of NO synthase and guanylate cyclase did not aftect significantly the relaxing effects of NSCH and SCH, NSCH and SCH inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs). NSCH and SCH decreased significantly heart rate. These, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In guinea-pig papillary muscle, these had no effects on parameters of action potential such as action potential amplitude (APA). V_max and resting membrane potential (RMP) at low doses, whereas inhibited the cardiac contractility at high doses. Furthermore, these had a significant inhibitory effects on palpitation of the heart in normotensive rats and SHRs. These results suggest that NSCH and SCH have weak cardiovascular effects, and that there is no significant differences between cardiovascular effects of two preparations.

전광 트리 네트워크에서 WRA 문제를 해결하는 알고리즘

김순석,여상수,김성권 중앙대학교정보통신연구소 2000 정보통신연구소논문집 Vol.2 No.1

본 논문은 전광 트리 네트워크상에서 WDM(Wavelength Division Multiplexing)을 이용한 파장 할당 및 경로 설정문제 즉, WRA 문제를 해결하는 알고리즘을 개발하는데 있다. 현재까지 전광 네트워크상의 임의 경로에 파장을 할당하는 문제는 NP-hard 문제[4]로 알려져 있으며, 또한 전광 네트워크상에서 주어진 노드쌍들을 연결하는 각각의 링크에는 서로 다른 파장을 할당해야 한다는 기술상에 제약조건을 안고 있다. 따라서 본 논문에서는 주어진 네트워크의 유형을 일반트리 형태로 한정지어 생각하고, 일반트리구조상에서 위의 제약조건을 만족하면서 논문 [5]에서 제안된 이론을 토대로 분할정복방법을 이용하여 실제 모든 경로에 파장을 할당하는 다항시간 알고리즘을 제안하였다. 제안한 알고리즘의 분석 결과는 O(Q·R)로, 여기서 Q는 일반트리구조상의 모든 노드에서 다른 모든 노드로 가는 요청 노드쌍들의 수이며 R는 일반트리구조상에서 모든 경로에 대해 할당할 수 있는 최대 파장수이다. 또한, 제안한 알고리즘을 펜티엄Ⅱ 233MHz에서 C언어를 이용하여 실험, 본 알고리즘을 검증하였다. This paper considers the problem of the WRA(Wavelength and Routing Assignment) in all-optical tree networks using WDM(Wavelength Division Multiplexing), where each connection between a pair of nodes in a network is assigned a path through the network and a wavelength on that path, such that connections whose paths share a common link in a network are assigned different wavelengths. The problem of optimal colouring of paths on all-optical networks is NP-hard[4], but if a network topology is a tree and the colouring of all paths, then exists an efficient polynomial time algorithm. In this paper, using divided & conquer method we give an efficient algorithm to assign wavelengths to the all paths of a tree network based on the theory of [5]. The time complexity of this algorithm is O(Q·R), in which Q is the request nodes for all-to-all communication in a tree topology and C is the maximum number of wavelength. Also We implemented our algorithm in C and analyzed performance results.
