Neuro-Fuzzy System is to combine merits of fuzzy inference system and neural networks. The neuro-fuzzy system applies a information about given input-output data to fuzzy theories and deals these fuzzy values with neural networks, e.g. first, redefines normalized input-output data as membership functions and then executes thses fuzzy information with backpropagation neural networks. This paper describes an innovative application of the Taguchi method for the determination of these parameters to meet the training speed and accuracy requirements. Results drawn from this research show that the Taguchi method provides an effective means to enhance the performance of the neuro-fuzzy system in terms of the speed for learning and the accuracy for recall.

In this paper we propose a new approach to the autonomous wall-following of wheeled mobile robots using hybrid system reference motion synthesis and generation. The hybrid system approach is in-troduced to the motion control of nonholonomic mobile robots for the indoor navigation problems. In the dis-crete event system the discrete states are defined by the user-defined constraints and the reference mo-tion commands are specified in the abstracted motions. The hybrid control system applied for the non-holonomic mobile robots can combine the motion planning and autonomous navigation with obstacle avoid-ance for the indoor navigation problem. Simulation results show that hybrid system approach is an effective method for the autonomous navigation in indoor environments.

Novel concept of shunt active filter (AF) function added in Photovoltaic (PV) generation system is described in this paper. So far, for the PV generation system has been treated as one of harmonic sources to the power distribution systems, not only a PV system combined with AF but also AF systems using PV module as their power source have never been discussed. The basic structure and control strategy of the PV-AF system are, for the first time, introduced in this work. In order to stabilize the output current of voltage source inverter (VSI), the reference voltage MPPT control is applied. Simulation analysis shows that it is possible to combine AF function to the three-phase grid-connected PV generation system without any physical difficulties, and the performance of the proposed PV-AF system is acceptable and stable as well.

To this is the concept and changes of physical treatment that intervenes the understanding and restoring cerebral infantile paralysis in the medical welfare of the social well-being areas: Cerebral palsy, originated by Littel in 1862 and reported as "The cerebral palsies" by William and Osler, come to have its name and meaning. The early stage of intervention generally accepted by the circle of physical treatment in the medical profession was introduced by Sax in 1964. In Sax' theory, cerebral palsy is defined as "the stumbling block in the bodily exercises and postures, causing by the intercurrent disease or physical, mental defect." As we have seen it is desirable that the abovementioned limited steps be removed and allow physical therapists to examine and to treat cerebral palsies. For this, first educational system should make its way to a substantial improvement and congenital abnormal Test should be rapidly expanding to great proportions the whole nation, not part of the low-income group. Physical therapists, cerebral palsies and their parents must combine to make cerebral palsies' welfare the crowning well being state. Physical therapists, cerebral palsies and their parents, forming of trinity, should combine to make cerebral palsies' welfare the Super-Welfare State existence.

Sister chromatid exchange(SCE) has recently become a common cytogenic assay system for detecting exposure to chemical mutagens and carcinogens. One application of SCE is the monitoring of populations believed to be exposed to such agents. A cross-sectional study of SCE frequency in peripheral blood lymphocytes from 40 college students aged 18 to 26 years was conducted. The effects of cigarette smoking alcohol and coffee consumption, dietary and environmental factors on SCE were assessed. A mean spontaneous SCE per cell for the smokers(4.88$\pm$0.17). The SCE levels of the smokers were associated with the personal smoking amount ; the observed increase in the SCE frequency correlated with the number of cigarettes smoked per day (P<0.05). There was no effect of age on SCE. There were positive linear relationship between SCE and food frequency score of meat and fish group (P<0.05) or instant food group(P<0.01) in non-smokers. But in smokers, a significant inverse association between SCE and food frequency score of green and yellow vegetable group(P<0.05). Alcohol intake produced a significant increase(P<0.01) of SCE in comparison with the mean SCE for those not drinking alcohol in combine subjects. Other dietary parameters, including coffee intake, use of artificial sweetners and processed foods, did not show any increase in SCE. SCEs were inversely related to blood glucose and serum cholesterol levels of the combine subjects. No significant correlations were found between SCE frequencise and any other hematological parameters of the subjects.

Recently, several attempts have been made to introduce the process concept to knowledge management (KM) or the knowledge concept to business process management (BPM) in order to combine the advantages of the two approaches. However, clear description about their interrelationship or a comprehensive framework to combine them has not been provided. This paper explores how KM and BPM can complement each other and proposes a framework to integrate the two paradigms. The concept of process knowledge proposed by this paper focuses on the importance of business processes as knowledge, which is overlooked by existing KM or BPM research efforts. The paper proposes a framework that combines and extends the functionalities of existing knowledge management systems (KMSs) and business process management systems (BPMSs) by identifying the functionalities required to manage process knowledge from the lifecycle perspective of both knowledge management and business process management. A prototype system is also presented to demonstrate the feasibility of the proposed framework.

Daily monitoring of the heart rate can facilitate detection of heart-related diseases in their early stages. Therefore, providing an easy-to-use and noninvasive heart rate monitoring system has been a very popular research topic in the field of healthcare. One of good candidate methods is to use commonly available cameras and extract information that can help to estimate heart rate from a human face. Generally, such information can be retrieved using two different approaches: photoplethysmography (PPG) and ballistocardiography (BCG). PPG exploits slight color changes caused by blood volume variations during heartbeats; thus, it tends to be vulnerable to unstable lighting conditions. BCG exploits subtle head motions caused by pumped blood travelling through the carotid artery during heartbeats; thus, it is vulnerable to the voluntary head movements that are not related to heartbeats. Nevertheless, most related works use either to estimate the heart rate. In this paper, we propose to combine two approaches to be robust to challenging conditions. Specifically, we explore possible ways to combine raw signals obtained from two approaches and verify that the proposed combination shows better accuracies under challenging conditions, such as voluntary head movements and ambient lighting changes.

After we looked back on the process western psychotherapy, and consider current meaning and necessity of buddhism. we concluded as follows 1. We can apply buddhism to psychotherapy in terms of oriental medicine. Especially buddhism with long history in the orient has similarity with oriental medicine and common cultural background. therefore it will be useful especially to koreans 2. Whereas buddhism's object is Nirvana, that of medicine is to return to the above view. to apply various methodologies of buddhism to psychology of oriental medicine you must select useful parts and drop others 3. Whereas buddhism centers on human mind, oriental medicine wholly describes body and mind without separation, buddhism put stress on inside of consciousness and oriental medicine put stress on revealing process 4. It is difficult to combine buddhism to oriental medicine theoretically. In combining it is easier to accept buddhism practically rather than theoretically 5. To apply buddhism clinically we have to modify buddhism to modern societies and to research and discussion to combine it to the system of oriental medicine
