Traffic accidents due to excessive speed frequently occur in places where traffic signal controllers are installed, places where sharp curves exist, or places where the traffic signal cycle does not match the current time. These traffic accidents cause economic loss due to the destruction of road facilities and structures, and cause a big problem of increasing the number of traffic accident deaths. When a traffic accident occurs, leaving a tire mark before or after a car crash, pre-collision speed of the car is calculated using the law of conservation of momentum or the skid mark formula. In the skip skid mark generated in ABS brake vehicles and the combshaped yaw mark generated by tire trace caused by lateral sliding, there is a difference of 30-40% in the reliability of the vehicle speed calculated by the smite mark. In this paper, we propose an algorithm that can improve the calculation reliability in vehicle speed by using skid marks in order to compensate for this problem. In addition, we present an intelligent speed calculation algorithm for traffic safety and a computer simulation in order to prevent traffic accidents by estimating the speed of a vehicle, using Skid marks, Yaw marks, and ABS brake characteristics and fuzzy rules.

Advances in information and mobile technologies have changed the traditional firm ways of working very flexible, collaborative and innovative, resulting in the changes in work place structures and layouts. Despite the growing body of literature examining the novel ways of working, which is called smart work, there is little academic attentions paid to the spatial aspects of new work places, namely smart offices and smart work centers. This research explores the spatial changes of work places that improve business efficiency and collaboration among workers suitable for the novel ways of working. Conducting in-depth field surveys on selected cases, we analyzed the changes in spatial structure and operation policies of smart offices and smart work centers. From this survey, we observed that the new work places under study take various novel spatial forms and they have flexible operating policies such as flexible seating and flexible work hours. We also found that it would be difficult to change existing business practices and typical ways of performing tasks, without changing the bureaucratic spatial designs and layouts. Future studies are suggested to examine how spatial structures and layouts of offices have impacts on space utilization, collaboration, creativity, and job satisfaction.

The rear garden of the Ch'angdok Palace is considered to be representative of gardens of the 15th century to the end of Choson Dynasty in the early 20th century and is very well preserved. Therefore with its long history, it's been represented in various way. This study tried to interprete the rear garden of the Ch'angdok Palace in terms of 'text through king Jungjo's "Sangrimshipkyog". Jungjo's "Sangrimshipkyng" that describes scenery related to ten place of the rear garden of the Ch'angdok Palace was written when he was a crown prince. And the scenery of ten places can't be separated from their physical looks and those ten places were quite different from now. For that reason, to begin with, this study recomposed those ten places through maps and drawings that revived the current looks and rear garden. And what poems tried to tell and what meanings whey had in the literacy of that age that allowed "poem enchained ten scapes" were studied in the context of co-relationship with space. As a text it is very ancient and questions arise on how to correctly interpret the information it holds. But this interpretation is only one side of the various aspects that the rear garden of the Ch'angdok Palace has compared to its long history. In light of the present age an interpretation can have richer and more varied meanings, creating many new viewpoints. creating many new viewpoints.

The main purposes of this paper are to determine the major factors influencing visual preference in soundproofing barriers in urban places and to provide the essential information needed in the design process of soundproofing harriers. This paper consists of two phases. The first phase presents photos of the seven types of soundproofing barriers generally seen around the Daejeon area, which were taken from three places for a photo montage. The evaluation of 21 different soundproofing barriers was conducted by college students. The second phase of this paper depicts the analysis process. Firstly, the visual preferences as found from the collected data were evaluated by five semantic degrees. The evaluated data were processed by descriptive test, a correlation test and ANOVA test methods using an SPSS statistical package. 1. Currently, visual preference in soundproofing barriers is low in urban places. Therefore, it is necessary to design visually pleasing soundproofing barriers to improve the visual qualify of urban areas. 2. Soundproofing barriers of mixed wood and acrylic scored the highest among selections while those with aluminium steel scored the lowest. 3. Environmental friendly and transparent conditions should be met to allow soundproofing barriers to be visually pleasing.

Based on residents' survey data in Seoul, this study attempts to empirically answer to four research questions regarding neighborhood relations (NR) which are necessary for community building: How important NR is compared to other social relations, what factors establish NR, how large NR's geographical extent is, and what are major meeting places among neighbors. A series of statistical analyses demonstrates that characteristics of NR vary greatly by family life cycle. In the stage of couple without child, NR has no significant meaning. NR becomes important from the stage of child care, and it is formed through the medium of children, particularly children's schools in the stage of child of elementary school as well as secondary schools. As the result, NR's geographical boundary extends beyond residential block or multi-family housing (apartment) estate while cafe and restaurant serve as dominant meeting places in these life cycle stages. On the contrary, after children are married and leave home, casual encounters resulted from spatial proximity become an important cause of NR. Likewise neighbors' geographical distribution is relatively concentrated within residential block or apartment estate, while community facilities play a role of meeting places as originally planned and designed.

The study examined the characteristics of internet shopping mall sites including on-line market places and integrated internet stores from a perspective of consumer protection. Specifically, the study investigated 1) whether sufficient information is provided on the internet shopping mall sites, 2) whether shopping mall sites abide by internet advertising principles, and 3) specific examples of consumer misleading potentialities from internet shopping sites. Further, on-line market places and integrated internet stores were compared based on their informativeness and potential consumer misleading factors. Total 50 shopping mall sites were analyzed for examining the types of information provided and consumer misleading factors. To verify study questions, descriptive statistics were used. For comparison between on-line market places and integrated internet stores, Chi-square test and independent-sample t-test were employed. The results of this study were as the following: First, not a few of the internet shopping mall sites did not provided important information such as safety and warrantees. Second, important disclosures were not noticeable on the web pages and distracting factors were frequently used. Third, integrated internet stores were desirable compared to on-line marketplaces based on informativeness and consumer misleading potentialities. As the result of this study, internet shopping malls need to advised to provide sufficient information and reduce potential misleading factors.

The purposes of this study is to identify a proper spot to create a symbolic place for the International Jazz Festival and to improve the connections among the place assets of Gapyeong as a place marketing strategies. To this end, the analysis and interpretation of spatial structure was conducted using space syntax. The results of the study showed that the entire structure of the space formed in the axis of a total of 200. The value of total integration was 0.833, which is relatively low, and the local integration degree was 1.588 degrees. Gahwa Street has the highest value of full integration (1.264) among the major points related with the Festival, followed by the former Gapeyong Station area (1.189). As a result, the former Gapeyong station area was identified as a recommendable place for symbolic place because it is highly accessible to the surrounding areas and spacious enough to function as a plaza. Developing a cultural street occupied by jazz cafes, concerts, shops and restaurants, and transforming the old railroad into a linear park will enhance the image of jazz city and help place marketing.

There can be two definitions of modern ideal medical surroundings. One is medical services satisfied patients' with their desire and the other is places suited to remedy realized by rational operation. Particularly, in case of dental service, there is a need for an effective regard of moving lines and there are many rooms for a dental service belonged to a curer and not a curer. So a design has been developed by many concerns. flow do we proffer more familiar and comfortable places to both a curer and not a cuter. Nowadays, the design is making progress to the unprecedented and up-to-date direction. I would suggest a general plan used by a nature of an original art for this design. The design used by a nature between human beings and things is able to induce comforts and intimacies. So to speak, I would like to remove artificial design and keep up organic lines, shapes and forms of a nature like it is. This study grasps the organizational limitation of this design and the visual characteristic of organic forms used by harmonious image of a nature and a new way is applied to limited medical places, a dental service, based on the study. Also, I'm go to examine the meaning and worth of a new design and suggest the direction of it.
