This study was done to provide an understanding of nursing in relation to the existential philosophy of the West and Buddhistic philosophy, It examined how human beings and death are interpreted and understood in existential philosophy as well as in Buddhistic philosophy. Then the study suggested that nursing should focus on helping the sufferer to find meaning and a sense of responsibility in his or her existence. When people have the opportunity to realize certain important but painful truths about their existence, they develop internal strength and control of their lives. Just as people learn to face their being, so can they come to terms with their non-being. According to the causal process in Buddhism, Human Being is not always annihilation of self. Therefore, birth, aging, disease and death go through the process of natural change and it is the appearance of human existence which is inherent in the health of every human being. To promote our health we must gain an insight about this phenomenon. This study viewed nurses' clients as 〈good friend〉 rather than 〈patient〉 which focuses on a disease-oriented concept. The concept of 〈good friend〉 views nurses' clients as active participants to create their life and as responsible persons in a constantly changing life. The study also examined the concept of recovery which means to come back to the previous healthy state and it suggested that the concept of recovery should be changed to 〈good change〉, because in existential philosophy, human beings are viewed as never going back to the past but moving on to the future by creating their existence. This study also suggested that nursing should help 〈good friend〉enlighten their existence to be free from pain and death and to get control over their existence.

This research is conducted to develop predictable method of real scale nanofiltration treatability with small scale nanofiltration experiments. As a result of comparing calculated values with measured values, they are in a good agreement for the concentrations in filtered water and concentrated water. The results of that are not affected by change of system recovery from 20% to 95%. The proposed method is produced using constant recovery of elements, that is, no considering the pressure change. we can predict filtrated flux and contaminant concentrations with the method. The method has the following steps. (1) Calculate recovery of each element with water quality level after fixing recovery elements, (2) Predict system recovery with recovery of elements in 1, 2, 3, and 4 banks, (3) Run small scale nanofiltration experiments in predicted water quality and (4) Simulate large scale nanofiltration system for forecasting actual water quality. As the cost for nanofiltration pretest will reduced if we use the proposed method, it will be a promising method for introducing nanofiltration to supply safe drinking water.

This paper proposes a new integrated navigation system for a mobile robot in indoor environments. This system consists of five frameworks which are classified by function. This architecture can make the navigation system scalable and flexible. The robot can recover from exceptional situations, such as environmental changes, failure of entering the narrow path, and path occupation by moving objects, using the exception recovery framework. The environmental change can be dealt with using the probabilistic approach, and the problems with the narrow path and path occupation are solved using the ray casting algorithm and the Bayesian update rule. The proposed navigation system was successfully applied to several robots and operated in various environments. Experimental results showed good performance in that the exception recovery framework significantly increased the success rate of navigation. The system architecture proposed in this paper can reduce the time for developing robot applications through its reusability and changeability.

The purpose of this research is to study the utility of prediction program like a F.E.M. analysis for energy recovery of heat exchanger with heat pipe which uses arbitrary groove wick. The program is based on the utility by the experimental and applytical method of the single heat pipe. It is also expanded and applied in the prediction program of the heat exchanger. The results are as follows; 1) The effective thermal conductivity of the groove wick with arbitrary shape is counted by the thermal resistance change. 2) The more the number of rows, the more the effect energy recovery changing by the number of rows, the bigger the free velocity, the smaller the effect of energy recovery. 3) The effect of energy recovery increases according to the value of the rate of mass flow (Me/Mc) and also number of rows. 4) The comparison between calculated and data shows good agreement within 2.5% error, therefore the F.E.M. analysis of the study is useful to predict the performance of heat pipe-heat exchanger.

In this paper, due to the network security defense is mainly static defense, a dynamic classification network security defense strategy model is proposed by analyzing the security situation of complex computer network. According to the network security impact parameters, eight security elements and classification standard are obtained. At the same time, the dynamic classification algorithm based on fuzzy theory is also presented. The experimental analysis results show that the proposed model and algorithm are feasible and effective. The model is a good way to solve a safety problem that the static defense cannot cope with tactics and lack of dynamic change.

Purpose: The aim of this study was to use fMRI and clinical prognosis criteria to evaluate therapeutic interventions in stroke patients with corona radiata infarct and acquire fundamental information about recovery mechanisms. Methods: Four subjects (2 men, 2 women) who had strokes with corona radiata infarct were recruited. For all subjects, motor functions such as motricity index (MI), modified brunnstrom classification (MBC), functional ambulatory category (FAC), and bathel index (BI) were evaluated. Evaluations were done at least 4 times over a period of approximately 6~7 months from stroke onset. We compared the final evaluation with the first. Results: All patients with corona radiata infarct showed improvement in motor outcomes with the passing of time. The strength of all patients improved from zero or trace levels to normal or good levels in the MI (Motricity Index) test. Other motor outcomes including the modified brunnstrom classification (MBC), the functional ambulatory category (FAC), and the bathel index (BI) also improved with the passing of time. Conclusion: Stroke patients with corona radiata infarcts change for the better over time. Therefore, one can introduce clinical interventions by the aspect of progress in functional motor recovery.

Purpose: The aim of this study was to present fundamental information regarding clinical prognosis and clinical criteria for therapeutic intervention in stroke patients with focal pons infarction. Methods: Four stroke patients (male: 2, female: 2) who were diagnosed with pons infarction were recruited. All subjects had motor functions evaluated using methods such as the Motricity Index (MI), the Modified Brunnstrom Classification (MBC), Functional Ambulatory Category (FAC), and the Bathel Index (BI). Evaluations were done at least 4 times over a period that was approximately 8~11 months from stroke onset. We compared the final evaluation with the first evaluation. Results: All patients with focal pons infarction showed improvement with time in motor function. The physical strength of all patients was improved to normal or good grades from zero or trace grades in the Motricity Index test. Also, other motor functions such as ambulatory capacity and activities of daily living (ADL) improved with time. Conclusion: Aspects of functional recovery and clinical prognosis are clearly predictable for specific patients with focal pons infarction. In addition, adequate therapeutic interventions can be provided clinical criterion to patients, according to aspect of functional recovery. Accordingly, patients with pons infarction change for the better over time.

Once-used $CO_2$-silicate bonded sand from domestic foundry is mostly discarded in a reclaimed land because of its bad collapsibility and reproduction properties. So this causes serious environmental problem. We can get 82% recovery of silica from used sand by scrubbing reclamation process in this research. When we repeat the reclamation-recycling of the foundry sand, artificial silica sand is broken down below 2-cycles, but natural silica sand does not destroyed when used repeatedly more than 10-cycles and have a good property of recycling with little change of its size.

Objectives : Ohyaksungi-san(Wuyaoshunqi-san) has been used for many years as a treatment for cerebrovascular diseases in Oriental medicine. This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san) on cognition and motor function recovery after ischemic brain injury, and also the expression of BDNF in hippocampus. Methods : This study was designed with 4 subgroups to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san). As control groups, group I has no treatment during 1 week after ischemic brain injury and group II has no treatment during 2 weeks after ischemic brain injury. As experimental groups, group III has been treated with Ohyaksungi-san(Wuyaoshunqi-san) during 1 week after ischemic brain injury and group IV have treated with Ohyaksungi-san(Wuyaoshunqi-san) during 2 week after ischemic brain injury. Each group has been examined by tests as follows, neurological motor behavioral tests, cognitive motor behavior test and histological test. Neurological motor behavior tests consisted of limb placement test, beam-walking test and horizontal wire test. Cognitive motor behavior test was performed by using Morris water maze. In the histological test, TTC(2,3,5-triphenylteterazolium chloride) staining, hematoxylin & eosin staining, and immunohistochemical staining were used. Results : 1. The tests for motor function recovery change had significantly good result in the experimental groups as compared with control groups(p<.05). 2. The Morris water maze test on cognition also had significantly good result in the experimental groups as compared with control groups(p<.05). 3. In the immunohistochemical staining for the expression of BDNF in hippocampus, more immune reaction was investigated in the experimental groups as compared with control groups. Especially group IV has the greatest immune reaction. Conclusions : Ohyaksungi-san(Wuyaoshunqi-san) has good effects on cognition and motor function recovery after ischemic brain injury, and also the expression of BDNF in hippocampus.
