Korean government plans to launch a lunar orbiter and a lander to the Moon by 2020. Before launch these two proves, an experimental lunar orbiter will be launched by 2018 to obtain key space technologies for the lunar exploration. Several payloads equipped in experimental lunar orbiter will monitor the surface of the Moon and will gather science data. Lunar orbiter sends telemetry and receives tele-command from ground using S-band while science data is sent to ground stations using X-band when the visibility is available. Korean deep space network will be mainly used for S and X-band communication with lunar orbiter. Deep Space Network or Universal Space Network can also be used for the S-band during trans-lunar phase when korean deep space network is not available and will be used for the S-band in normal mission orbit as a backup. This paper analyzes a visibility condition based on the combination of various ground antennas and its mask angles according to mission scenario to predict the number of contacts per day and to build an operational scenario for the lunar orbiter.

It's the situation that modern technological civilization shakes the life environment fundamentally without a serious reflection on the dangers. The sense of crisis' brought the rise of modern Ecology in awareness of survivability of the humanity. Because the serious reflection is not just a campaign for environmental protection, but is to establish the values which is possible to coexist and to make harmony between the nature and man, man and man, and to form a healthy relationship through philosophical thought and practice has intrinsic value for human and nature. Under these circumstances, if Yulgok lives now and he is questioned by the ecological theorists of the 21st century that "What do you think about the serious environmental problem of present times?", what really would be his explanation? In the presentation methods of the explanation, will question first what contents western ecologists who study Theory of the environment in technology, Deep Ecology, and Social Ecology propose, then will compare and introduce what similarities and differences from theirs. As a result, we'll be found that Yulgok's thought, moral consciousness, about the nature and humanity as a confucian scholar.

The low-temperatured radiant heating System like a panel heating system is recognized as nice means to make comfortable indoor environment. Perhaps, 'Ondol' would be a typical example of the Panel heating system. Nevertheless. Occupants in a radiantly heated Space which has an asymmetric radiant field may feel thermally discomfort due to the asymmetric radiation. The aim of this Study is to suggest the fundamental technical data for establishing Standards of thermally comfortable environment when designing a radiant heating System. Thermal distribution of indoor environment and the skin temperature of the occupants were measured at experimental room in KIER (Korea Institute of Energy and Resources). Whole/Regional thermal and comfort Sensation votes of the occupants were taken simultaneously in order to investigate the relationships between thermal environmental factor and the occupants' responses. The effect of an asymmetric radiation on thermal environment and the occupants' responses was analyzed by using a v.r.t.(vector radiant temperature). By this means, the thermally neutral limits for the ambient air temperature and the floor surface temperature by the occupants' responses were Obtained. And the recommended temperature limits of the indoor surface were derived from the experimental work and the theory of radiant and will provide thermal neutrality for man without any discomfort on the part of the body.

1. Objectives The pesent study purposed to examine Dongmu Lee Je-Ma's Sasang philosophy from the viewpoint of Che-Yong relation and to understand the effect of Che-Yong relation on Dongmu philosophy. 2. Methods First, we briefly compared the concept of Che-Yong relation in Jeongju philosophy, which has a dualistic philosophical structure, with the concept of Han Suk-Ji's harmonious Che-Yong relation, which has a monistic philosophical struaure and, based on rhe result, analyzed the characteristics of rhe concept of Che-Yong in Dongmu philosophy focused on Seongmyeong rheory, Sadan rheory and Hwakchung theory in ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$. 3 Results and Conclusions Jeongju philosophy is different from Dongmu philosophy in irs philosophical struaure characterized by Che-Yong relation, and the concept of Che-Yong in Dongmu philosophy forms the characteristics of Han Suk-ji's monistic harmonious Ole- Y ong relation. This produces results as follows. (1) Form a universal view of human beings centering of man's autonomous will and possibility. (2) Have a philosophical structure understood nor as a partial thought but as a total thought. (3) Assert that man has a good nature fundamentally and is obliged to practice goodness. (4) Assume that all human beings are equal. (5) It is assumed that the structural characteristics of harmonious Che-Yong relation in Dongmu philosophy can be the ground of definition of Silhak (practical science) in Oriental philosophy. It can be said that the realities of the universe and human beings can be discussed in philosophical structure with the logic of harmonious Che-Yong relation based on the unity of time and space. The philosophical logic based on the tealities can be defined as Silhak.

Nevertherless, a structural depression with high expense of costs-low degree of efficiency and high price of commodities-low degree of growth during the last few years. And hotel companys were doing endeavor for conquer this depression with reshuffle of the personnal system and that systematizing an enterprise and production control. Hotel has more increase personnel expenses percents than increase sold price percents so that hotel reducing cook and as result, hotel has a problem from production selling of food service because that is insufficient of cook man power. On studying this research, an importancy of cusine department in inquire hotel and an efficiency man power control of cusine department influence on hotel marketing were made use of analysis for hotel kitchen management. The result of this study is like that. First, the quality of a hotel employee is directly related to that of hotel service, which is functioned as a principle factor on which success or failure of the hotel very largely depends. Second, fair evaluation of merits. Third, cognition for job as expert. Fourth, the roles and competences of the employees were affected much by the inner or outer environmental changes surrounding the hotel enterprises. Fifth, do not underestimate an intelligent ability and will power of employee, and hotel company have to manage that the employees consult themselves about their things of department and improve with the master sense for job. Sixth, pay increase and intensive system. This system can raise the will to achievement for employee's job, and company can get many benefits from government. Seventh, the employees should be encouraged to have memberships of academic organizations, to actively participate in academic meetings, workshops, conferences, and forums in the area of job performance.

Human does information processing more efficiently using mental model at his understanding process. if We know what mental model is, we will know how to percept that. Similarly is it used visual mental model to percept visual object\ulcorner If it is true, we will analysis how man to understand. In this research, we have one experimentation to timid out that is true. So we did experimentation to know how man to understand new products by visual mental model. So we use 2700cc car's side view as stimuli. To A Subjects, we give them to see re\ulcorner size view before 120% ratio. To B Subject, we give them to see 120% ratio. After a experimentation, It is true that we make hypothesis that A Subjects percept this stimuli too long then B Subjects. Accordingly it proves human to use visual mental model to percept visual object. The result of experimentation, a testee use preliminary stimulus as basis of evaluation. It means that he use mental model as basis of evaluation of main stimulus. Accordingly development of new design can afford more strategic approach. Industrial designer who want to strategic approach can forced on high-weighted form attribute as consumer gives.

While watching the movie, the audience shows various emotional reactions. Emotional reactions such as sadness and anger, joy and anger appear depending on the storyline of the film. This aspect can be seen through the audience's brain wave response. This study is to examine the relationship between the movie story development and the movie story development through brain wave measurement of the emotional reaction of the audience in situations and events occurring in the movie development. Four American films, which represent each genre and are well known to many people, were selected for the study. These are of the adventure genre, of the animation genre, of the action genre, and of the drama genre. In order to measure the emotional response of these movies, four cases were set centered on the PPG of EEG and analyzed as a time series graph pattern. It can be seen that the emotional response on the graph has a certain relationship with the story development. It is expected that this study will help in selecting a genre when making a movie in the future, especially when deciding how to compose and develop a story, and it will help to induce the emotions of the audience.

Mt. Yeonae is at Gijang-gun in Busan and is surrounded by farming lands on three sides. The search for the species composition and dynamics of local communities were studied at Mt. Yeonae of how spatial similarity decays with geographic distance. The index values of Z$\ddot{u}$rich-Montpellier School's phytosociology at the 12 plots was compared to a distribution of similarly using 20 m quadrates at 12 sites. The specific communities were five including Pinus densiflora - Quercus variabilis community. Six species were significant similarity between neighboring sites by using the spatial autocorrelation coefficient, Moran's I. If Mt. Yeonae was destroyed by an artificial action, some spatial correlated species such as P. densiflora and Q. variabilis will be collapsed because of no maintaining the effective population sizes.
