The purpose of this paper is to propose a service system for a digital hologram video, which has not been published yet. This system assumes the existing service frame for 2-dimensional or 3-dimensional image/video, which includes data acquisition, processing, transmission, reception, and reconstruction. This system also includes the function to service the digital hologram at the viewer's view point by tracking the viewer's face. For this function, the image information at the virtual view point corresponding to the viewer's view point is generated to get the corresponding hologram. Here in this paper, only a prototype that includes major functions of it is implemented, which includes camera system for data acquisition, camera calibration and image rectification, depth/intensity image enhancement, intermediate view generation, digital hologram generation, and holographic image reconstruction by both simulation and optical apparatus. The proposed prototype system was implemented and the result showed that it takes about 352ms to generate one frame of digital hologram and reconstruct the image by simulation, or 183ms to reconstruct image by optical apparatus instead of simulation.

1. Objectives Theory of Iinsim Tosim(the Human - Mind and the Moral - Mind) that originated from "Sang-Seo(尙書)" "Dae-Woo-Mo(大禹謨)" is a relative importance point of dispute at the existing confucianism and chosun's neo confucianism. Our consideration point is that a close examination of relation between Iinsim-Tosim theory of existing confucianism's and Lee Je-ma's thought of Iinsim Tosim and his creative exposition that is related to view of human being contained theory of sasang(四象), knowledge & conduction(Jihang, 知行). 2. Methods of Research We analyze "Gyukchigo(格致藁)" that is contained confucianism's contents and Lee Je-ma's view point of human being, and consult " Dongyi Suse Bowon chobongeun(東醫壽世保元草本卷)", "Dongyi Suse Bowon(東醫壽世保元)", reference about confucianism and some other thesis. 3. Results (1) Lee Je-ma's thought of Iinsim Tosim is closely connected each other. There is close correlation between Iinsim and Tosim such as both ends. And Iinsim Tosim is not virtue and vice relation but all good concept, though each have fragility, Iinsim have weakness of laziness and Tosim have that of desire. (2) Lee Je-ma insist on having lisim(理心)-kyungsim(敬心) for overcoming each fragility that weakness of laziness and desire. And he present learning(學) and speculation(思) for acquirement of lisim(理心) kyungsim(敬心). (3) Lee Je-ma's thought of Iinsim Tosim's containing meaning is not one side but both side for nature(性) & emotion(情). therefore Iinsim Tosim is closely connected Lee Je-ma's view of human being and theory of knowledge & conduction(Ji-Hang, 知行論). That is very different from existing confucianism & MyungSunlock(Book of Illuminating Goodnes)'s thought. (4) Iinsim is connected with knowledge(知), Tosim is connected with conduction(行) (5) Lee Je-ma's thought of Affairs - Mind - Body - Objects(事心身物) is closely connected with Iinsim-Tosim. 4. Conclusions There are no parts that directly criticized by LEE JE-MA, comparing with he's thought and the existing confucianism's theory of Iinsim Tosim, a specific person's theory. but LEE JE-MA approached the theory of Iinsim Tosim with thought that is not an extension of existing confucianism's thought, but original with himself, therefore LEE JE-MA's thought of Iinsim Tosim is closely connected with the most important conceptions (theory of nature & emotion, theory of knowledge & conduction) at the Sasang Constitutional Medicine. and Iinsim Tosim is an important clue for understanding the thought of LEE JE-MA.

Purpose: We investigated the motivation of selecting major, the satisfaction of major and the view on occupation of emergency medical technology (EMT) students. The results of study will be used to increase the satisfaction of major of university students. Also, it can be used to support decision of major for high school students. Method: We conducted 1,586 surveys from 665 students at six four-year colleges and 921 students at seven three-year colleges. Our research period was from Aug. 27th to Oct. 31st in 2010. The surveys were analyzed by SPSS 18.0 using description statistics, t-test, ANOVA, Scheffe and Pearson correlation coefficient. Result: In our study, the motivation of selecting major is 35.8% of students selected 'good employment prospects', satisfaction of major's $M{\pm}SD$ is $3.15{\pm}.486$, adaptation of major's $M{\pm}SD$ is $3.11{\pm}.472$. The satisfaction of major show difference (t = 4.548 p = .000) by sex, also the adaptation of major show difference (t = 2.279, p = .023) by sex. The satisfaction of major show first grade students higher (F = 3.605, p = .013) than fourth grade students at four-year colleges. If satisfaction of major is high, accumulation evaluation score is high (F = 3.276, p = .011), too. Clinical practice experienced students was higher (t = -2.878, p = .004) than non experienced it satisfaction. In view of occupation, ideal job's factors and actual job's factors a lot of students selected 'aptitude'. Also, there is a statistically significant correlation (r = .618, p = .000) between the satisfaction of major and the adaptation of major. High satisfaction indicates high adaptation of major. Conclusion: In our study satisfaction of major and adaptation of major was very high score. EMT students concern about employment prospects at most. It is inferred that they select job which match with one's aptitude. We can suppose that students select major as a tool for employment by seeing result that a lot of students consider employment prospects at most when they select major. A method to improve the satisfaction and adaptation of major should be developed by realizing problems which occur the dissatisfaction of major. Also, there as on why students conflict between ideal and actual job should be revealed. There as on seems students want stable occupation in unstable job market situation. Therefore, the expansion of job matching aptitude and being stable should be processed. Finally, university should actively support the method that help to finding jobs for student by identifying job preparation of students.

The purpose of this study is to interpretate the Korean traditional Private Garden Pavilion -'byoul-seo(別墅)' in the view point of the architectural methodology - the separation of space in Honam province. It is presumed that nature union is archived through the 'yan-sang(玩賞)' which is ultimate state of knowledge that is base on the premises of opened signification in emancipation from narrow view point in the past and cognition of value. therefore, it is needed to know the unworldly point of space perception about the pavilion territory, furthermore to have conceptual method to distinct pavilion from the world. there are two methods in the distinct concept in this pavilion research: unworldly separation and meditative separation. As a result, the followings are conclusions; There two distinctive methods of planning of pavilion by use of the room and column. There are enclosement, turnaround, division of floor area in the room organization method, and it's modification of modulation, diversification of column height and diversification of column use in different space.

In ubiquitous computing environment, people expect services to change actively in response to the change of themselves and surrounding environment. In order to meet such expectations, the streaming service needs technologies for migrating through various devices, following the user's movement, and the technology of individualized streaming push service. In this paper, we designed and implemented U-Stream, a ubiquitous streaming service system, based on user-defined context and stream view. The system classifies contexts according to streaming service migration and allows users to define some contexts and, by doing so, provides user-oriented individualized services rather than uniform services based solely on the developers' anticipations.

The purpose of this study is to clarify the site selection and orientation which have affected the western missionaries in construction of the first western house in Cheongju area. The results of this study are as follows; In the site selection, they chose Tap-Dong hill, by finding the higher position and taking a fine view of all natural elements, because the alters like the tomb of Confucius, the existing settlement Godang village, Dang Mt. are already located around this area. And also it was that they could easily go into Tap-Dong hill through the existing alleys, These alleys, generated near the original road of Tap-Dong hill, are developed to modern road system. These alleys affect western house's entrance and orientation. In deciding the orientation of house, korean people prefer to south and east by considering Feng-shui theory; otherwise western house, specially the first house has a southwestern aspect, because the western missionaries have a preference for the topography, entry, and view than a house facing south.

Flexible forming process for sheet metal using reconfigurable die is introduced based on numerical simulation. Numerical simulation of sheet metal forming process is carried out by using flexible dies model instead of conventional matched die set. Elastic cushion which has high resilience behavior from excessive deformation are inserted between forming punches and blank material for smoothing the forming surface which has discrete due to characteristics of the flexile die. As an elastic cushion, urethane pads are utilized using hyperelastic material model in the simulation. Formability in view of surface defect such as onset of dimple is compared with regard to various punch sizes. Consequently, it is confirmed that the flexible forming process for sheet material has appropriate capability and feasibility for manufacturing of smoothly curved surface instead of conventional die forming process.
