Many themes have been studied for FMS problems. But most researches have focused on specific themes; Machine selection, Loading, Routing, Machine layout, etc. So many decision makers who want to introduce FMS to his factory, have many problems, because they do not know either what size of FMS should be introduced or what amount of money should be invested. The objective of this research is to help the decision makers who want to introduce FMS. This research consists of three major part, first, Machine selection, second, Loading, and third, Machine Layout. In the first part of the research, machines are selected with minimum cost satisfying the given demand of each part. In the second part, each operations with its required tools are allocated to those machines. In the third part the locations of each selected machines are determined. And dissimilarity coefficients between each pair of machines are calculated as the measure of distance. With above three steps, we have selected machines, allocated operations to those machines, and the layout configuration of those machines. And for each three steps, Mixed Integer Programming models are formulated. In order to solve the large problems and reduce the computer execution time, three heuristic algorithms are developed for the three mixed integer programming models.

The immune response to any stimulus is complex, requiring coordinated action by several types of cells in a tightly regulated sequence. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Although regular moderate exercise appears to be important factor for increasing immunity, Athletes are susceptible to illness, in particular upper respiratory track infection, during periods of intense training and after competition. In addition, in elite athletes, frequent illness is associated with overtraining syndrome, a neuroendocrine disorder resulting from excessive training. Through this paper, we want to investigate the effects of exercise on the immunosuppression such as exercise induced lymphopenia, asthma, anaphylaxis, URT (upper respiratory track), and TB (tuberculosis) infection. and also, we want to suggest a direct mechanism, protection and therapy of exercise induced immunosuppression.

NGIS project was carried out to accelerate Korea to an information-oriented land. NGIS Project also is to support training projects for GIS specialists as a sub-project. This program has two categories which are long-term courses and short-courses. The long-term courses are for people who want to get a job in SIS(Spatial Information System) field and also for public services personnel who want to acquire the latest SIS technology. Short-term courses are about the latest GIS component technology and utilization spatial data. In this paper, we analyze education programs and training courses relate to SIS. Also we suggest some directions to train specialists for the effective achievement of SIS project. To efficient education for SIS specialist, education programs have courses without repetition and courses are separated by technology type.

Up to row, researchers have observed experiment environment to study about raising procedure and an ecology of the ocean fishes with naked eye. Then they can monitor status information in only laboratory such as temperatures, image of the fish farm, etc. Such the existing way as this can't observe an ecology of the ocean fishes with scientific and systematic method and moreover it needs many of researchers. So in this paper, we design and implement a fish farm monitoring system which receives status of remote experiment environment through the internet whenever you want it and wherever you want it, and monitors and analyzes its status using embedded system of which the operating system is linux.

In this paper, We introduce the glove mouse using a Gyroscope, acceleration sensor, Pin-type Viboratctile Display Device and USB HID. The device recognize a user's wrist by Gyroscope and acceleration sensor in the glove and transmit the data to USB dongle which is recognized the manufactured mouse by Blutooth. Also, using a special application, We transmit the tactile information to user through the Pin-type Vibrotactile Display. We implement wearable system in the glove except USB device. If user want to use general spatial mouse, we recognize mouse USB dongle only without another application. If user want to feel the tactile sensationn, we can use by connecting PC serial communication port to USB dongle.

Recently, human's life is more longer and the birth rate continually decrease by the development of medical technology. In 2026 the ratio of the elderly will come up to 20.8% and be a 'post-aged society'. Development of economy and industrialization not only accelerate the urbanization and formation of nuclear family, but also change the changing of traditional society and one's value. So the issue of society and value's changing in the elderly increase the centralizing in the silver industry, and by the recent research about the elderly, they not want to live with their children, but want to live independently. This study is meaningful at the next generation of Ubiquitous society and post-aged society, proposing the smart silver town in urban type and let the elderly keeping the existing life in city. It realize the concept of 'Aging in Place' and propose the smart silver town in urban type which appropriate to behavior of the elderly, and being satisfy with various requirements of the elderly. This study point up the combination of physical elements and electronic elements through the smart technology, and making an smart environment to compose the smart silver town in urban type which react the behavior of the elderly.

The purpose of this study was to examine what parents really want to daycare center and how much they are satisfied with the daycare service they use. This study also explored how exactly daycare teachers recognize the parental needs and satisfaction on daycare service. One hundred and seventy one parents who send their child to a daycare center in Seoul, and one hundred and thirty five teachers from the same daycare centers participated in this study. Parents were asked about their needs and expectation on daycare service and the degree of satisfaction on the daycare center (including educational facilities, teacher's role, specific programs, etc.). Teachers provided answers about their understanding on what the parents want and how much parents are satisfied with their daycare center. Results revealed that parents are generally satisfied with the daycare service such as educational programs and educational facilities and teachers' role conducting. However, some parent-teacher differences were found in their perception on the levels and domains of parental expectation and satisfaction with daycare service. The parent-teacher differences would give very practical tips for teachers, who plan and conduct everyday daycare programs and actually interact with children in the setting for better daycare service.

In general, printed antennas have a narrow bandwidth characteristic and many people want to find out the method of bandwidth improvement through complicated procedures. So we want to reform the conventional printed antenna characteristic by using the folded dipole's superiority to unit dipole. But it is hard to feed the printed folded dipole antenna, we use the CPW, which is widely used in microwave IC or MMIC applications and have many advantages to the conventional microstrip line, to feed the printed folded slot antenna. It is confirmed that the improvement in the bandwidth characteristic of CPW fed folded slot antenna, as much as 20%, through the measurement of designed and implemented antenna.

Recently some negative opinions on milk, for instance, 'don't drink, if you want to live long' 'people who drink milk life-long, they suffer from arteriosclerosis' or 'milk is not helpful to osteoporosis, because it's acid food' etc. are confusing the regular consumers who believe milk is one of the best food, although milk has been used for a longtime since it was proved as the most nutritionally perfect food by many scientific researchers and medical doctors. According to the contents of negative assertion, experiments were carried out mostly targeting western people who are eating bread with butter everyday and taking large quantity of meat & milk, probably 2~3 times more than asian people. So, the probability of suffering from many diseases like obesity, hypertension, arteriosclerosis etc. is naturally high. Therefore, comparison itself between westerner and asian is not reasonable because of quite different food culture and fat intake far less. Milk has been contributing to the health of human for hundreds years supplying many nutrients, and this kind of contribution will last as long as humankind exist on the earth. However, milk is good source of many functional components, there are some people who can not drink milk. As a nutritionist said, milk is a kind of food, the only problem is quantity, people who can not digest milk can choose another and who want to drink milk, drink it as much as they need. That's all.
