The purpose of this project is to show the design of the outdoor area of the apartment being divided into main and necessary spaces, and then being divided into smaller spaces ideally based on the first few. Through this project, we were able to see an example of how the apartment community functioned after the smaller spaces were placed. After seeing this example, we created a more specific and subjective checklist. In conclusion, the outdoor space of the multi-family housing was first divided into five spaces including a living room, a space where physical activity is possible, a space where people socialize, one for economic purposes and apartment security, and space for entertainment. Afterwards, the five spaces were broken down into several smaller areas into a total of 41 smaller spaces. A checklist was made from the five main spaces being broken down to a more specifically detailed 41 spaces. This checklist, which is pointed out while handling the contract, is a helpful key in the foundation in order to satisfy future residents of the apartment.

Linear Programming is the most highly developed operations research algorithm currently in use. Virtually every reputable computing center has a version of the simplex method. This availability of a programmed algorithm greatly enhances the choice of linear programming. Linear Programming is also capable of handling exceedingly large problems, which of course is necessary if one wishes to optimize large structures. The linear programming formulation is conceptually more palatable to the mode of thought of the structural engineer than are some of the esoteric operations research algorithms. In this paper, therefore, a metrix set of nonlinear working stress constraints is derived by the stiffness method, following the network-topological approach and incorporating the working stress interaction conditions. And then, this nonlinear constraint set is transformed into the constraint set of a successive linear programming problem using the Taylor series expansion. The formulation is greatly enhanced by evaluating the Jacobian of the constraint vector function. The objective function of the nonlinear programming formulation for minimum volume design is derived by the relation between area and moment of inertia, and this nonlinear objective function is transformed into the linear by the Taylor series expansion.

동일한 선원에 대한 감마-감마, 감마-내부전환전자 각상관관계 실험을 통하여 변형핵인 ^152Sm의 혼합비(δ)와 121.8keV전이의 내부 전환전자 입자매개변수(b_2)를 결정하였다. 감마선을 검출하는데는 두대의 Ge(Li)검출기를 내부전환전자를 검출하는 데는 표면장벽형검출기를 사용하였다. 실험을 통하여 다음과 같은 결과를 구하였다. 244.7 keV-121.8 keV ; δ =-0.012±0.007 688.6 keV-121.8 keV ; δ =17.4±3.01 964.0 keV-121.8 keV ; δ =9.51±1.93 1112.0 keV-121.8 keV ; δ =12.30±2.05 1408.0 keV-121.8 keV ; δ =0.16±0.07 964.0 keVγ-121.8 keVe_K ; b_2=1.66±0.26 1408.0 keVγ-121.8 keVe_K ; b_2=1.63±0.10 1408.0 keVγ-121.8 keVe_L ; b_2=0.99±0.13 혼합비는 PPQ(Pairing-Plus-Quadrupole)모델과 IBA(Interacting-Boson-Approximation)모델로부터 얻은 이론값과 비교하여 보았고 또한 입자매개변수값이 이론값과 큰 차이가 있는 것으로 보아 변형핵의 저에너지 E_2 전이에서 ‘anomaly’가 있는 것으로 추정된다. The mixing ratios (δ) and the internal conversion electron particle parameters (b_2) of the 121.8keV transition in deformed ^152Sm nuclei were determined by comparing the γ-γ and γ-e angular correlation measurements made with the same source. The experimental apparatus was constructed with a surface barrier detecter for electrons and two Ge(Li) detectors for gamma rays. The following results were obtained. 244.7 keV-121.8 keV ; δ =-0.012±0.007 688.6 keV-121.8 keV ; δ =17.4±3.01 964.0 keV-121.8 keV ; δ =9.51±1.93 1112.0 keV-121.8 keV ; δ =12.30±2.05 1408.0 keV-121.8 keV ; δ =0.16±0.07 964.0 keVγ-121.8 keVe_K ; b_2=1.66±0.26 1408.0 keVγ-121.8 keVe_K ; b_2=1.63±0.10 1408.0 keVγ-121.8 keVe_L ; b_2=0.99±0.13 The results are compared with the theoretical values derived from the Pairing-Plus-Quadrupole model and from the Interacting-Boson-Approximation model, and an 'anomaly' was found in the low-lying E_2 transition for deformed ^152Sm nuclei.

The aim of this study is to identify the data traffic capacity of 3G mobile communication networks, especially of cdma2000-1X networks. Three-layered ON/OFF traffic model is used to describe the dynamics of data traffics and the process of data transmission such as packet scheduling. We construct a simulator fully incorporating packet handling process of cdma2000-1X data network as well as three-layered ON/OFF traffic model describing the behavior of source data traffics. To get influence of traffic parameters on performance measures, the extensive simulations were performed for several data sets which are obtained from real trace data or previous studies. The experimental results show that the engineered throughput satisfying QoS criteria is approximately 20% of total capacity. Finally, some proposals to improve the system capacity are followed.

This study was to investigate the tendency of the elderly housing policy in Korea, America, and Japan. The content analysis method was used to achieve the purpose of this study with laws, books and articles related to welfare and housing policy. The result are followed : 1.The elderly housing policy of Korea was started at facility house for homeless elderly in 1960s and then three generation sharing houses have been built in 1980s. 2.The elderly housing policy of U.S.A. was started in 1950s and the housing with fulfillment of elderly needs was provided in 1960s. The elderly housing with housework service was introduced in 1960s, but the elderly housing for low-income was decresed in 1980s. Vauteur program helped meet the various needs of the elderly. 3.The elderly housing policy of Japan was started in 1960s, The pair housing that was near child's house was provided in 1970s and the financial support programs for the elderly was started. Care service was added in the elderly housing with the pursuit of the quantative improvement in the sharing houses in Japan. The elderly housing policy in Japan is under stable stage in 1990s.

MPC860을 이용한 라우터 실현

송인근,황주원 우송대학교 2003 우송대학교 논문집 Vol.8 No.-

In this paper, we implement router for home networkings using MPC860 board. We install cross compile enviroments to support debugging mode for MPC860 board and choose Linux for OS in embedded systems. We also perform Linux porting focused on Linux kernel using Network File System and Ramdisk. As the results of this implementation, it is shown that PCs can exchange their data and obtain all of served internet services through router. Since our router has only one port, the results of test cannot satisfy sufficiently. It is also expected that time delay and overload in traffic handling will be reduced by means of increment of port number and enlargement of memory capacity for MPC860 board.

The interactions between nutrition and the endocrine system are more intimate and complex that previously thought. Nutrition modulates secretion and activity of many hormones, as part of the stress adaptation process. Fasting, in particular, produces a number of important changes in the endocrine system, with teleological purpose of helping the body tolerate the lack of food ingestion. These changes are therefore beneficial and protective, although at times they may not appear to be that way. The endocrine changes of fasting mediate the metabolic response. We must emphasize that these changes are completely reversible when appropriate nutrition is established. These changes are as followes: 1) decreased insulin and increased glucagon levels, 2) decreased thyroid effect, 3) decreased sympathetic activity, 4) hypothalamic hypogonadism, 5) decreased growth, 6) altered glucocorticoid secretion and metabolism, 7) impaired mineralocorticoid response, 8) decreased ADH secretion and effect. We experienced three cases of involuntary prolonged fasting after collapse of Sampoong department store. They were released from collapsed field after 11(case Ⅰ), 13(case Ⅱ), 17days(case Ⅲ) respectively. In each case, the endocrine changes of plasma levels were as followes: decrease of cortisol in case Ⅰ, increase of GH in case Ⅱ, decrease of free T3, T3, cortisol and increase of reverse T3, insulin in case Ⅲ. Each one did not show the same endocrine changes of plasma levels. But we think these changes of fasting are beneficial in metabolic response of human.

이병구,황학주,이원복 연세대학교 산업기술연구소 1975 논문집 Vol.6 No.1

Numerical data have been presented for the natural frequencies and modes of vibration of fixed, uniform, circular arches vibrating in their own plane, and the effects of the rotatory inertia and shear deformation affecting the response have been analyzed. The governning differential equations were solved numerically by a combination of a Holzer-type iterative procedure and an initial value integration procedure. The Runge-Kutta fifth order integration technique was used. The method was programmed for a Cyber 73-18 computer system, and all results were obtained on this computer system. A detailed study has been made of the lowest five vibration frequencies and mode shapes for a fixed arch with an angle of opening equal to 90 degrees. The effect of slenderness ratio and the influence of the rotatory inertia and shear deformation on frequencies are presented in detail in curves.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.
