In the case of a linear time-varying system, it is difficult to apply the conventional stability conditions of RHC (Receding Horizon Control) to real physical systems because of computational complexity comes from time-varying system and backward Riccati equation. Therefore, in this study, a frozen time RHC for a linear discrete time-varying system is proposed. Since the proposed control law is obtained by time-invariant Riccati equation solved by forward iterations at each control time, its stability can be ensured by matrix inequality condition and the stability condition based on horizon for a time-invariant system, and they can be applied to real physical systems effectively in comparison with the conventional RHC.

Computer simulation is one of the most useful techniques to predict daylighting performance and present visual image. In architectural and interior design practice, the Lightscape is commonly used often to produce persuasive images rather than physically accurate results. Therefore, this study is to validity the Lightscape as daylighting evaluation tool, in particularly performance and realistically visualization. For the purpose, an evaluation test model (12.0m$\times$7.2m$\times$3.0m) of side lighting window with lightshelf was selected. A 1:6 scale plywood physical model was made. Under clear sky condition, illuminance of 84 Interior point were measured. Lightscape was run on a 750 MHz Pentium PC running Windows 2000 under the same sky condition. And a photography image was compared to rendering image. The physical results of interior illuminance were within 8% between the scale model and Lightscape simulation. There were no differences between the photograph image and rendering image by Lightscape in the sight. Lightscape as visualization tool for daylighting performance was validated.

Until now, research reports that it is difficult for brokenup floc after coagulation to reaggregate and settling efficiency of reaggregated floc is relatively low have dominated in water treatment process. In contrast, from recent study conducted by the French researcher, because the density of the reaggregated floc was higher than the previous floc, the settling efficiency of reaggregated floc increased. In this study, 15 times wet test were carried out and the removal efficiency of reagrregated floc was considerably increased. Moreover, this result was explained using the turbulent model for the flow occurred around the floc. Consequently, in the case of suitable hydrodynamic condition for the reaggregation, the characteristics of the reaggregated floc was changed into the favorable condition for improvement of settling efficiency. Also, the most important factor for reaggregation of floc was governed by hydrodynamic shear stress.

The condition of covering process using thermoplastic polyetherester elastomeric fibers(TPEE) was established. Two types of core yarn(TPEE, Spandex) and one type of effect yarn(PET) were used as materials to confirm the change in physical properties of covering yarn under various covering conditions. In addition, the effects of the treatment temperature on the elongation at break of covering yarn after heat treatment was analyzed. Through this analysis, it was confirmed that the elastic recovery of TPEE which is used as the core yarn was increased with the draw ratio, but decreases when it exceeds 1:2.5. And the elongation at break of the covering yarn could be increased by increasing the twist per meter of it. Additionally, it was confirmed that the elastic recovery of TPEE which is used as a core yarn, could be increased by applying heat treatment.

This study was performed to investigate the characteristic of physical touch in caring situation. The subjects of this study were adults in caring situation, therefore they were composed of 7 patients, 6 nurses, 3 doctors, 3 pharmacologists, 3 men in paramedicine area, 3 nursing educators and 13 normal general adults. The datas were gathered through nonstructured questionaire from June, 20th to September, 15th in 1995. The datas were subjects' descriptions about the intention, perception, and form of physical touch in caring situation and analysed by content analysis. The results as follow : The datas were divided into four areas. There were the situation being necessiated the physical touch, meaning of physical touch, form of physical touch and perception about physical touch in caring situation. The situation being necessiated physical touch were the situation that required physical treatment, to deliver the active expression of concern about the patients, to determine the treatment due to the identification of physical condition of patients and to induce the psychological eqilibrium into patient's mind. The meanings of physical touch in caring situation were - Good meanings that intention is to encourage, to be have hope about health and to deliver the affection willing to help patient. - therapeutic methods that were to facillitate the circulation of blood, to reduce the pain perception and to facillitate the circulation of qi. - interpersonal affectionate relation that the intentions were to deliver the understanding of patient's pain, were to delivery the meaning to the patient not be alone. The forms of physical touch in caring situation were none invasive forms just like laying hands on hand, head, shoulder, gentle knocking on the shoulder or back, massage of legs and back and finger pressure on acupuncture points. The perception of physical touch in caring situation divided into two parts. In family, the perceptions of physical touch in caring situation were to promote health status because physical touch induce the psychological peace, and to evoke the importance of relationship among family members. In relation with care giver, perception of physical touch in caring situation were inevitable process in treatment, and to deliver the trust and concern about patients.

The purpose of this study was to investigate the effect of Treadmill Training with FES(TTF) on walking velocity, gait endurance, and energy expenditure index(EEI) of hemiplegia patients with foot drop. Two subjects with hemiplegia participated in this study. They took walking excercise 5 times per week for 8 weeks. One time excercise spent 30minutes. The theraputic effect was evaluated by how many seconds they needed to walk 10 meters, how far they could walk for 12 minutes, and how much they spent energy in walking for 12 minutes. Two cases were examined before, after 4 week, and after 8 week, walking training. The results of this study are as follows; 1) Walking velocity : Case 1 increased from 0.52m/sec before walking training to 0.83m/sec after 8 weeks. Case 2 increased from 0.58m/sec to 0.92m/sec. 2) Gait endurance : Case 1 increased from 383.23m to 625.53m. Case 2 increased from 410.19m to 693.47m. 3) EEI : For comfortable walking condition, Case 1 decreased from 0.98beats/min to 0.71beats/min, and Case 2 decreased from 0.93beats/min to 0.68beats/min. For maximum walking condition, Case 1 decreased from 0.93beats/min to 0.67beats/min, and Case 2 decreased from 0.91beats/min to 0.61beats/min. The findings suggest that hemiplegia patients can improve their walking velocity, gait endurance and energy expenditure index through TTF.
