This study did by purpose to be utilized to basic data for elevation of human rights consciousness of homeless facilities employees through examining their human rights consciousness by investigating human rights sensitivity that can grasp degree of human rights consciousness of homeless facilities employees. The human rights sensitivity of 390 homeless facilities employees who are working at 38 facilities around the whole country is compared and investigated. As a result, human rights sensitivity of employees displayed very low score by average 64.55 points in total score 150 points. Human rights sensitivity academic career of employees was shown meaningful difference, and human rights consciousness of substantial administrator is appeared very low in human rights sensitivity by duties. According to the existence and nonexistence of human rights education at the homeless facilities, the employs who had got human rights education shows higher human rights sensitivity than the employs who had not go human rights education. Therefore, regular program that can enforce human rights education Collectively as a formal curriculum in homeless facilities should be established and it's proposed to develop practical and efficient human rights education manual case by case related with the violation of human rights.

This study aims to figure out how green tea leaves, mulberry leaves, and mate leaves that are often taken around in drinking tea influence on S. mutans known as dental caries causative bacteria. After vaccinating 1% of S. mutans on the extract added badge and incubating 6 hours and 10 hours in $37^{\circ}C$, it calculated absorbance and bacterial colony number. Extract of green tea leaves and mate leaves were added with 0, 0.5, 1.0, 2.0, and 4.0% of concentration. As a result of growth suppressive effect of S. mutans, it may be observed that colony number significantly decreases in higher concentration. When it calculated bacterial colony number with adding 2% extract after 10 hours, 99.0% for green tea leaves, 97.1% for mulberry leaves, and 89.6% for mate leaves appeared.

Daytime surface zooplankton were collected bimonthly from April 1993 to March 1994 at six stations around upwelling and adjacent areas of Cosan, western part of Cheju Island. This paper deals with the occurrence, biomass and some other characteristics of zooplankton in these areas. Copepods had two peaks in the abundance in June $(235\;ind./m^3)$ and November $(301\;ind./m^3)$, but were not especially abundant in upwelling area. While gelatinous organisms seldom occurred in the upwelling, and the outer area with high density of $75\;ind./m^3$ (in June) and $458\;ind./m^3$ (in November) at the intermediate area, seasonal values of biomass with mean of $35.8\;mg/m^3$ were the highest in November and the lowest in January. Abundance of chaetognaths (mainly Sagitta spp.) ranged $15\~37\;inds./m^3$ and carcasses of Sagitta occurred very highly in the upwelling area in June ($54\%$ of total Sagitta organisms) and November $(70.5\%)$. Especially $48\~77\%$ of Sagitta individuals in upwelling area in November was attached by Oncaea mediterranea, O. venusta and Candacia bipinata. Pteropods with shells were sampled only in the upwelling area during strong upwelling season (November, $27\~64\;ind./m^3$), indicating the characteristics of ascending behavioral adaptation from the bottom water by upwelling.

The species composition and seasonal variations of fish community in the Zostera marina belt at the coastal water off Hamduck, northern part of Cheju Island, were analyzed based on day and night samples collected by a small beam trawl from May 1993 to May 1994. The dominant species among the 58 fish species in 35 family were tubesnout, Aulichthys japonicus, gobie, Pterogobius zonoleucus, filefish, Rudarius ercodes, pipefish, Syngnathus schlegeli and sea catfish, Plotosus lineatus. These species comprised 86.1% in the number of individuals and 62% in biomass. The number of individuals and biomass were high between October and December, and low between January and April. About 90% of fishes were noncommercial and small-sized fishes, less than 14cm in total length. The larvae and juvenile fishes were collected in the study area throughout the year. The recruitments of dominant species were related to the seasonal variations of Z. marina utilized as a shelter or feeding ground. A japonicus, P. zonoleucus, Zoarchias glaber and Hexagrammos agrammus recruited between January and June, and R. ercodes, S. schlegeli, P. lineatus and Petroscirtes breviceps between July and December.

When people are shopping at a large shopping mall, they usually become to go around many stores for looking for better products and comparing them. In this paper, we design and implement a purchasing activity support system based on an Ambient Service Model that provides relevant stores information on map interface hierarchically through user contexts based search, to support such user's purchasing activities with the help of relevant information. In this system, users can search for relevant stores information through the system by Ambient Query which is created by their location and stores information with a mobile device. Then, users obtain relevant stores information provided in the form of hierarchy of keywords as a highly condensed summary and easily figure out the locations of the stores on a map interface. Moreover, users search additional other kinds of relevant stores information over the hierarchy of keywords. Eventually, users can obtain relevant stores information intuitively and conveniently without complex search processes. We implemented this system by integrating the subordinate technologies such as RFID, map-based, location-based and ontology technology. We also performed experiments on a well-known shopping region (Ilsan Lapesta shopping mall, Goyang-city Gyeonggi-do, Korea). Finally, we also confirmed that users' shopping activities were significantly improved by utility the present system.

There are about 22,000 national control points throughout this nation. However, in order to identify the location data of a national control point, a control point result table is needed. And although the control points are important national facilities, due to the fact that these points located at remote areas such as on top of mountains, the facilities are being maintained via on-site inspection without any protections around them. In this research, by taking the locations where the control points are placed into consideration, a specialized RFID tags that can be attached to the national control point's marker has been developed, and CDMA-ready PDA based mobile Web System and national control point control system are developed as well. With help of these systems, control point data can be checked at the seen, and national control point maintenance personnel can find out about maintenance status and keep track of usage record. When these systems are taken into effect, access to the national control point data becomes easy, fast response to the change in data can be possible, and management efficiency will go up. When the Ubiquitous society becomes reality, the importance of location information will be high. Therefore, national control points using above mentioned RFID tags will not only be useful to the control point users and maintenance personnels such as professional land surveyors, but also useful when providing location based services to people, and it will become an important national infrastructure in terms of providing absolute location information.

TV display which existed only in house started to show up out of house around us and now it found naturally its place in everywhere like street, bus, subway and elevator. It is called digital signage which showed up through digitalization of sign, that is, sign board and bulletin board. The distinction of digital sign from existing signs is that the latter one should go through physical process like removal after installation every time its contents are changed but the former one can produce its various outputs flexibly once it is installed. Also existing sign may be static image or 2 or 3 pieces of image to express simple motion while digital sign can contain multi media contents luxurious in design and motion. This paper confined the range of contents in digital signage in bus and subway. It needs to analyze characteristics of mass transportation-people of use, consumer by place and time, accommodation environment for consumer etc and arrange planned contents along with time and place. Developments of dedicated contents suitable to those digital signages will harmonize with place and time and promote the realm of digital signage which provides variety of experience to consumer and with which communication is possible and which is distinctive. Furthermore we may expect the birth of smart signage as a new media, in which fun and art are combined.

This is a study through survey with the purpose of analysing of treatment cost for arthritis. Treatment cost can be devided Into two characteristics, one is the direct cost and the other is the indirect cost. Direct cost contains fees of medical treatment Including cost of self treatment & purchsing price of herb durg. On the other hand indirect cost means the using money of tansportation, lodging charge & labor-losing-time cost. For the succession of medical treatment of chronic diseases patients have to control themselves to go shopping around for the cure remeadies. And also it is important that the cost for unefficient or probably hamful folk remeadies should be reduced in order to distribute appropriatively the limited financial resources. As the result of this study, the fees for self treatment & herb drug are two times as much as those of regural medical treatment. Within the direct cost, there are the mean cost of regural medical treatment 59,630 won/mon., self-treatment 42,790 won/mon., and herb drug 78,380won/mon. therefore total mean direct cost is 180,800won per month. Moreover patients intermittently pay the cost of prostheses If folk remedies, these are added to the direct cost as above mentioned. Attributes of folk remedies are various from cure & analgesics to nutrients and their virtues as medicine are not clear in view of scientific knowledge. But 56% of arthritis patients have ever been experienced folk remedies. the cost for these remedies has wide ranges from 40,000 won to 1,000,000won. Total mean indirect cost including the transfortation fee, lodging charge & labor-losing-time cost has the range from 82,825won/month to 106,150won/month. Among these cost, labor-losing-time cost has a mojority because the waiting times are too long for seeing a doctor. In conclusion those patients having arthritis have a large burden against the treatment cost for continuous care. Therefore health professional should make effort to guide the patient to determine themselves informed choice about the treatment process.

In the DBB delivery system, the design stage and the construction stage are separated. Because of this, design changes frequently occur, and problems such as construction cost overrun, schedule delay, and quality deterioration happen as well. Recently, in the construction industry CM at Risk(CM@R) delivery system, which can systematically solve the above-mentioned problems of DBB delivery system, meet various demands of clients, and overcome the limited cost and period. In the CM@R delivery system, the contractor negotiates for a maximum guaranteed price(GMP) with the client at the design stage, and the CM performer carries out the construction within the GMP. However, uncertainties are inherent in the GMP calculation because the calculation is based on unfinished drawings and documents. In this study, a Probabilistic Earlier GMP Calculation Method by combining a probabilistic tool of Monte Carlo simulation with a case based reasoning is proposed so that the uncertainty in GMP calculation is reflected. After the earlier GMP is calculated, a process to calculate the $2^{nd}$ GMP at the time of around 80 % of detailed deign and to negotiate with the client to fix the final GMP is proposed. The Probabilistic Earlier GMP Calculation Method is verified through the case study. In this study, researchers set the range of GMP through the proposed probabilistic GMP calculation and tried to reduce the risk through negotiation between the client and the CM performer. The proposed method and process would contribute to the successful introduction of CM@R in Korea.

In this paper, we introduce an efficient GPU-based real-time rendering technique applicable to every kind of game. Our method, without an extra geometry, can represent terrain just with a height map. It makes it possible to freely go around in the air or on the surface, so we can directly apply it to any computer games as well as a virtual reality. Since our method is not based on any geometrical structure, it doesn't need special LOD policy and the precision of geometrical representation and visual quality absolutely depend on the resolution of height map and color map. Moreover, GPU-only technique allows the general CPU to be dedicated to more general work, and as a result, enhances the overall performance of the computer. To date, there have been many researches related to the terrain representation, but most of them rely on CPU or confmed its applications to flight simulation, Improving existing displacement mapping techniques and applying it to our terrain rendering, we completely ruled out the problems, such as cracking, poping etc, which cause in polygon-based techniques, The most important contributions are to efficiently deal with arbitrary LOS(Line Of Sight) and dramatically improve visual quality during walk-through by reconstructing a height field with curved patches. We suggest a simple and useful method for calculating ray-patch intersections. We implemented all these on GPU 100%, and got tens to hundreds of framerates with height maps a variety of resolutions$(256{\times}256\;to\;4096{\times}4096)$.
