This study conducted influencing and mediated effect on stroke to lead correct health behavior of stroke patients and tried to provide preliminary data of stroke prevention. It used stage 4 and 5 data of a national health and nutrition examination survey, analysis method was frequency analysis, Chi-square test, multiple logistic regression and structural equation modeling. In case of male, factors affecting to stroke were age, job, self-related health, alcohol, hypertention and diabetes. In case of female, age, job, self-related health, stress level and hypertention affected to stroke. In tested results on whether or not mediated effect of preceding disease exists, 5.80 difference in ${\chi}^2$ between partial mediated modeling and full mediated modeling was statistically significant(p<0.01). Therefore, partial mediated modeling was adequate to this study. We need preventive health education for changing wrong health behaviors and policy that strengthens health care network. If someone has preceding disease, they need long-term diagnosis for health condition and continuous improvement in life style.

Visibility of lane marking is impaired at night, or in case of rain, and thereby threatens traffic safety. Recently, various studies and technology have been developed to improve lane marking visibility, such as the extension of lane marking life expectancy (up to 1.5 times), improvement of lane marking equipment, improvement of lane marking visibility (32.7%) by applying phosphorescent material mixed paint, and expressway lane design standards alternative (length 6m, gap 12m, width 13cm: 27.8% of painted surface are reduced) adoption with ergonomic analysis. In this study, a set of cost-benefit analyses was performed for the cases where such techniques were applied. Based on the literature review, 26.9% of traffic accidents would be prevented by improving lane marking visibility by 32.7%; accident reduction benefit was calculated as much as 12.5 billion KRW. Meanwhile, total increased cost when introducing phosphorescent material mixed paint and lane design standards alternative is calculated as 30.6 billion KRW. However, economic feasibility could not be secured with 0.41 of cost-benefit ratio when applied to the expressway network as a whole. Additionally, cost-benefit (B/C) analysis was applied to each of the top 20 night accident hot spots and the results of B/C ratios were between 0.67 and 4.20, showing that 11 out of 20 spot sections of expressway can have economic feasibility. This results indicate, with this kind of pavement marking applied to accident hot spots in rural expressway, better visibility and economic feasibility can be guaranteed through traffic accident reduction. Some limitations and future research agenda have also been discussed.

The mobile phone and wireless network, location based technology and other newly introduced technologies and communication media gave birth to the new terminology "ubiquitous" and are changing our daily life. Influence of such technologies and communication media is not an exception in the arts. New media art pieces using these technologies are increasing, and taking on the characteristics of public art within a wider scope of a city as a backdrop, beyond the traditional boundaries of art galleries. Of such art, locative media art using locative media has a closer relationship with city space than any other form of an, and makes various attempts to allow the spectator to reinterpret and experience city space and induce communication. These characteristics of locative media art can be considered as a method that can solve quality problems of the city space, especially the loss of the sense of place and the absence of communication. is one such locative media project with a purpose of solving quality problems of city space, especially the recovery of commercial sites and inducing communication. This project uses the paths of the city as its canvas, movement of people as its brush, the color of the roads as its pallet, and by allowing the partakers to draw paths of their own and to share their paths with others. People are encouraged to share stories about their paths. The project proceeds using barcodes that are frequently used commercially. When users wish to create their own place, they can enter their place and colors of their choice using input devices installed in the city space. Paths that are created through such a process will be displayed in public areas throughout the city, shared with others, and can create and share a stories about the city using on/off-line media.

The development in smartphone technology has brought convenience to the life of the mankind, but an excessive use of smartphones sometimes causes various accidents. This research tried to propose an application service 'Smombie Safe Go' UI(User Interface) that allows the prevention of such accident while using smartphones when walking. For this, after research and user observations, produced walker journey maps and derived necessary main functions needed for safety, and the result showed that transparent interface, obstacle location alert, warning of dangers functions were necessary. To make the contents of the service more detailed, hazardous situations faced during smartphone use when walking were classified into 3 situations : 1. Obstacle appearing in front, 2. traffic lights on crosswalks 3. No traffic lights on crosswalks. Scenarios by hazardous situation were written, and the flow and UI of the app service that warns its users in each situation of hazards were designed. it is predicted that 'Smombie Safe Go' may be possible to be utilized as an app service that provides a safe walking experience for not only regular pedestrians but also the blind population.

This study identified degradation properties by temperature stress with Araldite$^{(R)}$ AY103-1/HY956 used for ceramics. Tensile and compressive strength of durability increased for 6,480 hours at temperature of $34{\sim}45^{\circ}C$. In stability of external stress and temperature, compressive strength is superior to tensile strength, it requires conservation plans considering strength properties and stress of restoration materials. The tensile shear strength of adhesion properties decreased for 4,320 hours at temperature of $40{\sim}60^{\circ}C$. In ceramics with porosity, environments under isothermal-isohumidity are important because interfacial properties of adherend are concerned with performance variation. Glossiness decreased for 6,480 hours at temperature of $34{\sim}45^{\circ}C$ and color difference increased. Gloss stability was superior and color stability was weak, which requires improvement of optical properties. In artifacts on display in museums, there is concern about temperature rise on restoration materials by lighting therefore, it needs to minimize change in physical properties by exposure environments.

The present study explores the problem of the placelessness and alienation through spaces of redevelopment in South Korean animation film since the 2000's. Actual space in South Korean society has been destroyed and changed unceasingly, and, in that space, humans have experienced existential conflict. While the swift development of digital technology has transcended physical restrictions to form one great network, humans are still limited as materially based beings. The recent steps in South Korean animation film are noteworthy because sociocultural changes since the 1990's and the relationship between the individual and the system are perceived in ways different from those of the past. and , the works analyzed in the present study, reveal the special sense of place in South Korean society, where the destructive reorganization of space leads to the instability of life. By intentionally bypassing a sense of place and the authority automatically bestowed on representational images, these works prompt the viewer to reexamine the relationship between reality and images. Space in these two works are presented representationally but immediately destroyed, and humans or the characters in the works accept this unfeelingly. The loss of place, which is committed by the massive system, and listless humans' weakness and alienation in response are depicted as signs of sociocultural abnormality. By showing the destructive loss of place and individuals who respond with self-anesthesia and self-estrangement, these works open viewers' eyes to South Korean society, where not only social alienation but also self-alienation is occurring. By perceiving South Korean animation film as a sociocultural phenomenon and analyzing it through the concepts of the placelessness and alienation, the present study seeks to expand further discussions on animation film.

While the Internet keeps its permeation into every aspect of human life, two things stand out. One is the requirement for high quality of services to support multimedia data service.'The other is the desire for ubiquitous network connection. Combining the two things makes the Internet possible in supporting multimedia communications for nomadic users on the locomotion. To support QoS communication for mobile users by applying RSVP to Mobile IP, RSVP Tunnel, which specifies building separately a RSVP session between the home agent and the foreign agent, was proposed. However, the RSVP Tunnel method breeds bandwidth overhead and association problems in tunnel because of duplicated RSVP messages use. To resolve these problems, in this paper, we propose the new encapsulation method, the RSVP-in-IP Encapsulation (RIPE) that can support QoS guaranteed service efficicntly in Mobile IP networks. The proposed method supports RSVP mobility to Mobile If tunneling mechanism efficiently without any additional session as the RSVP Tunnel scheme. Moreover it removes the critical problems of bandwidth overhead in a tunnel and association by duplicated messages. We compared the performance of our proposed scheme with RSVP Tunnel scheme in term of mean delay, mean data rate and bandwidth overhead in tunnel.

BACKGROUND/OBJECTIVES: Type 2 Diabetes mellitus (T2DM) is a hereditary disease that is also strongly dependent on environmental factors, lifestyles, and dietary habits. This study explored the relationship between lifestyle habits and glycosylated hemoglobin management in T2DM patients to provide empirical outcomes to improve T2DM management and patient health literacy. SUBJECTS/METHODS: This study enrolled 349 diabetic patients with more than 5 care visits to a Diabetes Mellitus care network under the Health Management Plan led by Taiwan Department of Health (DOH). Based on relevant literature, an Outpatient Record Form of Diabetes Mellitus Care was designed and lipid profile tests were conducted for data collection and analysis. RESULTS: When modeling the data, the results showed that the odds for HbA1c > 7.5% in T2DM patients duration over 10 years was 3.785 (P = 0.002) times that in patients with disease duration of fewer than 3 years. The odds of HbA1c > 7.5% in illiterate patients was 3.128 (P = 0.039) times that in patients with senior high school education or above. The odds of HbA1c > 7.5% in patients with other chronic illness was 2.207 (P = 0.019) times that in participants without chronic illness. Among 5 beneficial lifestyle habits, the odds of HbA1c > 7.5% in patients with 2 or 3 good habits were 3.243 (P = 0.003) and 3.424 (P = 0.001) times that in patients with more than 3 good habits, respectively. CONCLUSION: This empirical outcome shows that maintaining a good lifestyle improves T2DM management and patients' knowledge, motivation, and ability to use health information. Patients with longer disease duration, education, or good lifestyle habits had optimal HbA1c management than those in patients who did not. Thus, effective selfmanagement and precaution in daily life and improved health literacy of diabetic patients are necessary to increase the quality of T2DM care.

A Lifelog management system provides users with services to store, manage, and search their life logs. This paper proposes a fully-automatic collecting method of real world social contacts and lifelog search engine using collected social contact information as keyword. Wireless short-distance network devices in mobile phones are used to detect social contacts of their users. Human-Bluetooth relationship matrix is built based on the frequency of a human-being and a Bluetooth device being observed at the same time. Results show that with 20% of social contact information out of full social contact information of the observation times used for calculation, 90% of human-Bluetooth relationship can be correctly acquired. A lifelog search-engine that takes human names as keyword is suggested which compares two vectors, a row of Human-Bluetooth matrix and a vector of Bluetooth list scanned while a lifelog was created, using vector information retrieval model. This search engine returns more lifelog than existing text-matching search engine and ranks the result unlike existing search-engine.
