Recently, the historical displeasure of celebrities caused a problem that the people were scolded by the people. On the other hand, people's historical consciousness is rising for a series of broadcasts organized by a famous entertainment program. We are now in the idea of our country people like this in history when history will not be left unsaid thing about realism. Inmates because there is a powerful force that is, that media is the 'immersion' players are interested more in the game, it is important to do it. Therefore, the history of games are made based on players to attract attention and interest or historical fact and to make a feature of the game and character.Does not occur to production. So correct history can have a sense of history the players are in fact this study, based on the development called an 'the mythology of the millennium' in 'hq team', manufactured. Choose the game. Scenario is based on thorough historical facts of the game 'the mythology of the millennium' authority order to conduct verification of the historians made it. These production process to appear in the game 'King Gwanggaeto,', 'Geunchogo of Baekje' and 'muyeorwang' design and comparative analysis to the historical facts.

A terrain is an essential element for constructing a virtual world in which game characters and objects make various interactions with one another. Creating a terrain requires a great deal of time and repetitive editing processes. This paper presents a 3D terrain reconstruction system to create 3D terrain in virtual space based on real terrain data. In this system, it converts the coordinate system of the height maps which are generated from a stereo camera and a laser scanner from global GPS into 3D world using the x and z axis vectors of the global GPS coordinate system. It calculates the movement vectors and the rotation matrices frame by frame. Terrain meshes are dynamically generated and rendered in the virtual areas which are represented in an undirected graph. The rendering meshes are exactly created and updated by correcting terrain data errors. In our experiments, the FPS of the system was regularly checked until the terrain was reconstructed by our system, and the visualization quality of the terrain was reviewed. As a result, our system shows that it has 3 times higher FPS than other terrain management systems with Quadtree for small area, improves 40% than others for large area. The visualization of terrain data maintains the same shape as the contour of real terrain. This system could be used for the terrain system of realtime 3D games to generate terrain on real time, and for the terrain design work of CG Movies.

In this paper, we propose ubiTrack, a system which tracks users' location in indoor environments by employing infrared-based proximity method. Most of recently developed systems have focussed on performance and accuracy. For this reason, they adopted the idea of centralized management, which gathers all information in a main system to monitor users' location. However, these systems raise privacy concerns in ubiquitous computing environments where tons of sensors are seamlessly embedded into environments. In addition, centralized systems also need high computational power to support multiple users. The proposed ubiTrack is designed as a passive mobile architecture to relax privacy problems. Moreover, ubiTrack utilizes appropriate area as a unit to efficiently track users. To achieve this, ubiTrack overlaps each sensing area by utilizing the TDM (Time-Division Multiplexing) method. Additionally, ubiTrack exploits various filtering methods at each receiver and utilization module. The filtering methods minimize unexpected noise effect caused by external shock or intensity weakness of ID signal at the boundary of sensing area. ubiTrack can be applied not only to location-based applications but also to context-aware applications because of its associated module. This module is a part of middleware to support communication between heterogeneous applications or sensors in ubiquitous computing environments.

The current employment status among young home economists and perspectives in occupations for prospective Home Economics graduates were explored in this study which utilized information from 17 to 21 colleges in Korea and colleges in the United States during the five years of 1977∼1981. The Home Economics content areas covered in this study were Clothing and Textiles, Foods and Nutrition, Housing and Interior Design, and Child Development and Family Life. The highest percentage of Korean graduates in Clothing and Textiles was employed either as teachers at the junior high school level or as designers in the clothing and textile industries. Quite a number of the graduates were engaged in further studies at the graduate level. Korean graduates with a master's degree were teaching at the college level and some had furthered their studies at the doctorate level either here or abroad. Koreans with a bachelor's degree in Foods and Nutrition held jobs as teachers in junior high school, dieticians at mass feeding institutions and hospitals, food scientists in food industries, and researchers in institutions. Those with a master's degree were teaching at the college level. Americans with a bachelor's degree worked as dieticians, supervisors in restaurants and institutions, extension workers, researchers at various facilities, teachers and clerks. Americans with a master's or doctorate degree were engaged in teaching at colleges or supervising at research or working as extension specialists. In general, Korean graduates were found to hold positions in less varied areas than their American counter-parts. Among forty-nine graduates those working in their professional field reported less sex discrimination that those working in other fields. The major area of employment in Housing and Interior Design or Home Management graduates in Korea was teaching while in the United States it was extension work, business, governmental work and teaching. It was suggested that in the future, career development in Korea be further explored to include extension service, research, social welfare, financial planning, business, free-lancing, funeral home, home-call, and correctional education. Interviews with executives from 6 business enterprises indicated that most of them were aware of the potential contribution home economists could make for their companies but they expressed a negative attitude towards women in general due to their short stay on the job. Jobs held by Child Development and Family Life majors with a bachelor's degree in Korea were mostly teaching positions in public, junior and senior high school. However, jobs such as nursery school teaching, working in clinical setting, business, and teaching at public, junior and senior high school predominated in the United states. Most Korean graduates with a master's degree were teaching in professional colleges while in the United Stated the job variation among the graduates was rather evenly distributed among teaching at college level, public and high school, nursery school and administration areas. Reports from 7 child development majors on the job indicated that they were paid less that secretarial workers. Only half of them were working in their major area and these expressed satisfaction with their work. Two thirds of the respondents indicated no sex discrimination. It was suggested that in the future Child Development and Family Life majors pursue employment in counseling, guidance, recreation, mass media, administration and outreach work as well as education, research and parent education in services for children, teen-agers, adults and families.

We propose a method to select representative views of single objects and classes of objects for 3D object retrieval and classification. Our method is based on projected 2D shapes, or views, of the 3D objects, where the representative views are selected by applying affinity propagation to cluster uniformly sampled views. Affinity propagation assigns prototypes to each cluster during the clustering process, thereby providing a natural criterion to select views. We recursively apply affinity propagation to the selected views of objects classified as single classes to obtain representative views of classes of objects. By enabling classification as well as retrieval, effective management of large scale databases for retrieval can be enhanced, since we can avoid exhaustive search over all objects by first classifying the object. We demonstrate the effectiveness of the proposed method for both retrieval and classification by experimental results based on the Princeton benchmark database [16].

To improve crop productivity with optimal water management in soilless culture, the information of physical characteristics of the root medium including water behavior should be required. The objectives of this study were to analyze the physical characteristics including hydraulic properties of the root media commercially used and to analyze the relationships between actual moisture content and measured one by FDR sensor. The weight of the medium was measured by load cell for calculating the actual moisture content. The accuracy of the moisture content measured by FDR sensor was obtained by comparing with the actual one. The water holding capacity of the coir was lower than those of the rockwool due to the features of large and rough particles of the coir. The moisture content measured by FDR sensor showed large difference from the actual moisture contents measured by loadcell, indicating that the calibration of FDR sensor is needed before starting measurement. The optimum range of moisture content for irrigation control was narrow in the coir than the rockwool due to the lower water holding capacity and rehydration capability of the coir. The results of this study can be useful in establishing adequate irrigation strategies in the soilless culture.

Despite the sizable growth of the group buying market, consumer complaints have recently raised skepticism about the future of these sites. Thus, building a trustworthy transaction environment has become a critical issue. In exploring a trust-building mechanism, we pay particular attention to the role of merchandisers who specialize in finding products or services and marketing them to potential buyers on group buying sites. The purpose of this study is to examine whether providing merchandiser feedback comments and performance profiles on group buying sites leads consumers to evaluate the community of merchandisers more favorably and makes them more likely to purchase products or services. Research hypotheses were tested with data obtained from 124 subjects who participated in a laboratory experiment. The results empirically demonstrate that merchandiser feedback comments and performance profiles enhance buyers' trust in the community of merchandisers participating in a group buying site. This enhanced trust, in turn, increased buyers' intention to purchase products or services through the group buying site.

Streptococcus pneumoniae is a common cause of acute otitis media, sinusitis, pneumonia, and the invasive bacterial infections in children. Rarely, S. pneumoniae is an uncommon cause of hemolytic-uremic syndrome (HUS). We report a 33 month-old girl who presented with pneumonia, and subsequently developed HUS. Her pulmonary infection was complicated by necrotizing pneumonia and acute respiratory distress syndrome. Cultures from blood and pleural fluid grew S. pneumoniae, serotype 19A. She was treated with antibiotics, dialysis and mechanical ventilatory support. She was discharged with normal renal function after 2 months of management. She remained healthy without renal complications at the 5 year follow-up visit.

Commercial formulation of fungicides was studied in vitro for sensitivity against Typhula species causal agents of Typhula blight. Efficacies of fungicides application, spray volume, nozzle types and fungicides applied time (early fall and late fall) were evaluated for their influence on the chemical control of Typhula blight of turfgrass during the winter season in Wisconsin. All fungicides effectively reduced the mycelial growth of eight isolates of Typhula spp. in vitro on potato dextrose agar (PDA) media. For inhibitory effects on mycelial growth of eight isolates, propiconazole was the most effective at $1.0{\mu}g$ active ingredient (a.i) / ml of PDA. Typhula incarnata two isolates were significantly more sensitive to all fungicides of PDA than six isolates of three varieties of T. ishikariensis. For 2 years in field experiment, unsprayed control has significantly more disease severity than seven fungicides were applied to field plots at two locations. Propiconazole was the most effective for controlling Typhula blight, at two locations in both years. The level of disease control was not dependent on fungicides spray volume or nozzle types at two locations. The disease damage treated with triadimefon applied time (early fall and late fall) was not significantly different at two location for two years.

Objectives : This study was to examine the state of customized visiting oral health programs in a bid to help facilitate the unified operation of the programs and the development of required guidelines. Methods : The subjects in this study were 49 dental hygienists who were professionals responsible for customized visiting health care programs across the nation. Results : 1. Regarding the form of employment of the dental hygienists were investigated many contract and daily workers. 2. As to the possession of equipment necessary for visiting oral health programs, denture cleaners(12.2%) were most widely possessed in some regions, followed by mobile scalers(10.2%) and mobile suctions(8.2%). In terms of expendable devices and materials, dental mirrors, pincettes and explorers were the most widely possessed dental checkup devices, and the most widely possessed oral hygiene supplies were toothbrushes, interdental brushes and denture cleaners. Those devices and materials were in more possession than the other types of devices and materials. The most widely possessed equipment for educational purpose was laptop computers, followed by beam projectors and screens. The most widely possessed teaching materials were dentiform, followed by CD-ROMs. 3. Those whom they visited the most for oral health care service were elderly people, followed by the disabled and patients with chronic diseases. The dental hygienists who went out to visit those people outnumbered the others who stayed at public health centers. Concerning the types of visiting oral health care service, the most prevalent service provided to the elderly included denture cleaning/management, oral massage and preventive treatment against dental caries. The most dominant service provided to the disabled involved education of the oral health care act, preventive treatment against dental caries and toothbrushing by professionals. The most common service offered to patients with chronic diseases was education of the oral health care act and oral health education. The dental hygienists paid a visit to a mean of 5.8 households a day. The average weekly number of households cared by the dental hygienists was 27.3. It took a mean of 37.1 minutes for them to take care of each household. 4. As for satisfaction level with the implementation of the visiting oral health programs, they expressed the greatest satisfaction at teamwork with professionals($3.56{\pm}0.94$), followed by the professionalism of their work($3.21{\pm}0.94$) and workload($3.08{\pm}0.94$). Their satisfaction level with the work conditions required for creative job performance($2.75{\pm}0.98$) and partnership with other institutions($2.64{\pm}1.03$) was below 3.0. In regard to the impact of their characteristics, marital status made a statistically significant difference to satisfaction level with workload. The unmarried dental hygienists were more pleased with their workload than the married ones(p<0.05). 5. As to needs for education for professionalism improvement, they asked for education about visiting oral health care skills the most, followed by education about oral health care for patients with chronic diseases, education of planning/evaluation and education of oral health care for the disabled. Conclusions : The top priority for the vitalization of the programs was the procurement of budget, followed by the procurement of equipment and educational media and the procurement of human resources.
