Objectives: The purpose of the present study was to explore the relationships between views on suicide, death, and life and lifetime suicidal attempts in the Korean context. Methods: Multiple logistic regression model was tested using data from Korean General Social Survey of 2009. We utilized the nationally representative survey data obtained via multistage stratified area probability sampling design from 1,599 respondents aged ${\geq}18$ years. Results: The proportion of lifetime suicidal attempts was 12.1% of entire sample in Korea. Some components of views on suicide and death influenced significantly on lifetime suicidal attempts after adjusting for demographic and health-related factors. The positive view on suicide(OR=0.76, 95% CI: 0.62-0.94), the naturalistic view on afterlife(OR=0.37, 95% CI: 0.67-0.99) and death concern(OR=0.67, 95% CI: 0.55-0.83) were risk factors of lifetime suicidal attempts. In contrast, the social responsibility view on suicide(OR=1.17, 95% CI: 1.00-1.37) and the transcendental view on afterlife(OR=1.25, 95% CI: 1.02-1.54) lowered the risk. Conclusions: Practical implications of the findings were discussed exploring policy evidences to screen high risk groups out and to reframe educational programs for suicide prevention. Strategic health messages need to be developed and transmitted for prevention of suicide.

Now, the representative researching trends of view managements for improving the query processing in multi-database system are focused on the materialized view mechanism and the signature view index mechanism. But when we compare with both mechanisms, the former mechanism's access time is faster than one of the latter's, and needs large space. The latter mechanism needs small space and the access time is slower than one of the former. These mechanisms are trade-off each other. Therefore, in case of query process using the view management, we are to improve the system performance and to reduce the access cost of disk input and output by suggesting a new mechanism mixing both the materialized view mechanism and the signature view index mechanism. We suggested that the structure of metadata and the algorithm about the new mired mechanism.

Realistic real-time rain streaks rendering has been treated as a very difficult problem because of various natural phenomena. Also, in creating and managing a large number of particles, a large amount of computer resources had to be used. Therefore, in this paper, we propose a more efficient real-time rain streaks rendering algorithm by generating view-dependent rain particles and expressing a large amount of rain even with a small number. By creating a 'rain space' dependent on the field of view of the camera moving in real time, particles are rendered only in that space. Accordingly, even if a small number of particles are rendered, since the rendering is performed in a limited space, an effect of rendering a very large amount of particles can be obtained. This enables very efficient real-time rendering of rain streaks.

Driver's view has blind spot of automobile surroundings due to physical components of automobile architecture. Obstacles on blind spot are the cause of car destruction and car accidents. Cars which produced in recent have obstacle detection sensors and rear view cameras which provide information of obstacles on the blind sopt, and have also AVM(Around View Monitoring) which provides automobile surroundings for driver's safe driving. During a low-speed travel while parking or moving in a narrow street, a driver get help for safe driving by taking information of automobile surroundings using the above-mentioned devices. In this paper, we present a design and implementation of a 4-sided monitoring (4SM) system, which helps a driver see an integrated view of a vehicle's perimeter at a glance, using a car PC connected to four cameras installed on the front, rear, left, and right sides.

Geographical Information System(GIS) was established to display the calculation results which show the concentration change with time and regions in case of an accidental release of radionuclides from Kori Nuclear Power Plants. GIS included the commercial program, ArcView(ESRI), and a basic digital map of 1:5000 scale lot 20km by 20km around Kori area. The object for the presentation was $^{131}I$ concentration in rice which is one of staple foodstuffs. Provided by deposited $^{131}I$ concentrations, ECOREA-II code computed the $^{131}I$ concentration of the soil and the plant in the area divided by In unit cells in total, in which the concentrations also varied with time. The results were introduced into the attributed data of previously designed polygon cells in ArcView. In order to display the concentration change with time by monotonic color, the RGB value for ArcView color lamp was controlled. This display definitely helped the concentration change around Kori area be acceptable to public.

Purpose: It is very important to evaluate and fix coronoid process fractures because they are a critical element for a stable, effective elbow function. The lateral view of the elbow joint is used for a radiographic evaluation of the coronoid but an understanding of the fracture pattern is often difficult because of overlap of the radial head and obliquity of the fracture line. We developed the coronoid view, which is a new radiograph for an evaluation of the coronoid process fracture, and discuss its advantages for a postoperative follow-up. Materials and Methods: The coronoid view was designed for an evaluation of the anteromedial fragment of the coronoid process. After the patient sat on his side, the shoulder was abducted $45^{\circ}$ and the elbow was flexed $90^{\circ}$. The X-ray beam was shot perpendicular to the table. Since shoulder was abducted $45^{\circ}$ the fracture line of the coronoid process can be parallel to the X-ray beam, and the radial head can be cleared. Conclusion: The coronoid view can be a good alternative radiograph for an evaluation of a coronoid process fracture because the beam is parallel to the fracture line. The coronoid view can be particularly useful in postoperative patient follow-up where computed tomography is impractical due to metal implants and cost.

Since townscape planning zones were introduced in 2000 by a revised Urban Planning Law, interest and understanding on townscape have been enhanced in Korea. Driven by this trend of the time, interest in townscape planning has been growing in the area of urban planning, and local governments have been expressing their interest in townscape management. This study is intended to provide criteria for setting goals of constructing desirable urban environments in harmony with existing condition in Chung-ju City. To this end, questionnaire surveys and awareness research were administered and following findings were obtained in relation to user-specific preferences on view targets and view points for townscape planning in Chung-ju City. In general, citizens of Chung-ju City were found to prefer townscape frequently in use practically, while residents in other areas preferred such townscape as linked with the city' s overall reputation. Both groups were found to prefer natural landscape (Gaemyeongsan, Namsan, etc.) to artificial one as a view target, and Chung-ju Terminal and the neighborhoods and downtown(Seongseo-dong) were presumably preferred as a view point.

A window increases the lighting quality of a space by allowing daylight into the space, and maintains visual contact with the outside. Moreover, the window with a preferred view provides many benefits such as psychological satisfaction, occupants' health and improved environmental quality. This study aimed to investigate how view elements and window luminance influence occupants' seating preference in a living room. The experiment was carried out in a mock-up model with thirty-two subjects (17 men and 15 women). The nine seating positions in a living room have different view such as natural view (trees or sky) and man-made view (paving and roof top). Subjects were asked to select a position in the room where they felt most visual comfort. Simultaneously Photolux 2.1 software was used to analyze the window luminance. The experiment results indicated that subjects prefer to be seated near a window and feel comfort in a seating overlooking the trees and sky. This would indicate that the natural elements of the view and a distance to the window affect seating preference to the occupants.

Many Korean palaces such as Deoksu Palace and Kyungbok Palace are located in downtown Seoul. Modern high-rise buildings around the palace have been the background scenery of traditional architecture in it. In this case, such landscapes mixed with traditional images and contemporary images can give a negative impression to visitors watching from inside the palace. In this study, we analysed the correlation between landscape image of Deoksu Palace and trees' view blockage of buildings around it with three independent variables. The first variable is completely blocked view of buildings around the palace by the trees. The second variable is half-blocked view of buildings around the palace by the trees. The third variable is the view of buildings around the palace that is not blocked by the trees. The analysis showed that there were some significant correlations between landscape image of Deoksu Palace and trees' view blockage of buildings around it. It also showed that the view blockage ratio by the trees has positive correlation with improvement of landscape image of the palace.
