Because of developing medical science, lengthening the average life span and so on, the population of the elderly goes on increasing. The population of the healthy and high-income old people are increasing, also. So this study aimed to grasp the facilities and program situation of the welfare hall for the elderly as a welfare-leisure institution. The elderly be going to a hall are anticipated too many, based on the number of the hall per local old people. The majority of the hall are organized similar spaces and progams in them. There are almost not different things among the welfare halls and the locations. So they should be set on the aged' higher requirements and the old man's need varying in different localities. Also, 'gyoungrodang' remodeled in facilities and programs near their houses is likely to be recommended as the nest best thing.

To investigate anti-stress effects of Manual Kigong, Manual-Apparatus Combined Kikong, and Systemic Kigong, this experiments were performed changing of plasma catecholaminess and serum cortisol measured. Also using D.I.T.I(Digital Infrared Thermongraphy Imaging), Pulse Analyzer, Electric Current on Neurometer, and Digital Flicker on Testing-Stressed. And following results were abtained. 1) Menual-Appartus Combined Kikong decreased significantly increasing concentration of plasma epinephrine and norepinephrine level in Testing-stressed. 2) Manual Kigong decreased increasing concentration of serum cortisol level in Testing-stressed. 3) Manual Kigong and Manual-Aparatues Combined Kikong increased decreasing thermomerty on the palm's center caused Testing-stressed. 4) All of three treats are small change in SET(Systolic Ejection Time) by Pulse Analyzer caused Testing-stressed. 5) More changes of Electric Current on the Neurometer Diagnosis caused Testing-stressed are as followed. Manual-Apparatus Combined Kikong >Systemic Kigong >Manual Kigong From the results, it may be concluded that Manual-Apparatus Combined Kikong Theraphy having more anti-stress effects than Manual Theraphy. Systemic Kigong Therapy.

With the increasing performance and density of VLSI scircuits as well as the popularity of portable devices such as personal digital assitance, power consumption has emerged as an important issue in the design of electronic systems. Low power design techniqeus have been pursued at all design levels. However, it is more effective to attempt to reduce power dissipation at higher levels of abstraction which allow wider view. In this paper, we propose a simultaneous scheduling and binding scheme which increases the correlation between cosecutive inputs to an operation so that the switched capacitance of execution units is reduced in datapath-dominated circuits. The proposed method is implemented and integrated into the scheduling and assignment part of HYPER synthesis environment. Compared with original HYPER synthesis system, average power saving of 23.0% in execution units and 14.2% in the whole circuits, ar eobtained for a set of benchmark examples.

An experimental study was conducted to investigate the influence of the spinning control cylinders which was set on the surface of a fixed circular cylinder in uniform flow, $Re=1.24\times10^4$. The measurements of velocity vectors and pressure distributions are carried out in various spin parameters and angles of spinning control cylinder. The results show that velocity profiles and pressure distributions are different with angles of control cylinder and spin parameters. When the control cylinder angle is $100^{\circ}$, there is more effect in increasing the velocity and the pressure distribution than other cases. In this case, the vortex shedding frequency was increased as increasing spin parameter.

After we made the computer source code with mathematical model of Muramatsu et al. that was expressed by the set of simultaneous first-order ordinary differential equations in evaporation-pyrolysis zone of cigarette, we simulated the distribution profiles of temperature and density of flue-cured tobacco. Those equations were solved numerically with the Runge-Kutta-Gill algorithm assuming step size of 0.025mm by Muramatsu at at,, but in this study the advanced algorithm of Runge-Kutta 4th Order assuming step size of 0.0005mm. The initial conditions and physical parameters of Muramatsu et at. were used for solving them. The calculated values corresponded well with results of Muramatsu et al., especially the gradient of the temperature profile increased with smoldering speed and the thickness of the evaporation-pyrolysis zone decreased with increasing of smoldering speed. On the other hand, the temperature gradient decreased with increasing of the effective thermal-conductivity value and the thickness of the evaporation-pyrolysis zone increased with the effective thermal-conductivity value.

This study has focused on the possibility for recycling tailings from the Sangdong tungsten mine as admixture for concrete. The XRD(X-ray diffraction analysis) and PSA(Particle size analysis) were performed to find mineralogical characteristics. As a result of XRD analysis, the tailings were composed of quartz, feldspars and muscovites, and C-S-H and quartz were found in cement mortar. As a result of KSLT for cement mortar mixed with tailings, most of heavy metals were determined as below the guide line for waste material. In addition, the setting time and compressive strength of cement mortar mixed with tailings were investigated. It was indicated that the initial and final set were retarded according to increasing replacement. The compressive strength of mortar was decreased with increasing replacement.

The maintenance management in buildings has got more important by the increasing complexity of building sizes and use. Nowadays an expectation and a possibility of BIM technology become accepted as a new construction management method, therefore many studies and legal systems of it are being suggested actively. Although orders for BIM projects are supposed to be increasing, at present the BIM information accumulated from planning and design still doesn't have its continuity at the maintenance step after completion of construction in terms of LCC. Therefore according to bim information, we set a goal of developing apartment maintenance system which is able to maintain by user and administrator viewpoint.

By using the notion of fuzzy functions introduced by Dib and Youssef, we obtain fuzzy analogues of some results concerning ordinary functions. In particular, we give the denition dierent from one of invertible fuzzy function introduced by Dib and Youssef. And we show that the two denitions are equivalent. Furthermore, we introduce the concepts of fuzzy increasing functions and fuzzy isomorphisms, and we obtain fuzzy analogues of many results concerning ordinary increasing functions and isomorphisms.
