In the context of lifelong education program for an aging society and information age, elementary school facilities are expected to accommodate various people in diverse age group and diverse physical abilities. Introduction of the 'Universal Design' concept seems inevitable in school environment in terms of public infra structure for community. However, in architectural point of view, unlike foreign examples, simply applied barrier-free and safety standards of domestic guidelines based on dimensional data does not function enough to achieve universal design in authentic manner. This study is focused on this issue and suggests the direction of improvement for architectural design guidelines. Through the comparative analysis of foreign and domestic design guidelines, two principles of universal design-'Flexibility in Use', 'Perceptile Information'- are found to be lacking in the domestic design guidelines for elementary school facilities. It is expected for government authority to develop more concrete guidelines to achieve universal design for school as a basic public space in the community.

There are a variety of apps that are finding their way. And in car navigation, we launched a product that reflects Augmented Reality technology this year. However, existing apps have problems. It is implemented in 2D or 3D, has a large error range because it has been modified in most vehicles, is not updated in real time, and car augmented reality navigation is a vehicle, and a separate device is required, etc. In this study, we implemented a smartphone app for walking directions using augmented reality, and made it possible to intuitively use a route service from a user 's location to a destination. The Dijkstra algorithm is applied to calculate the shortest path to solve the problem of finding the route with the least cost. By using this application, it is possible to use the route search service even in a data-free environment, to solve the inconvenience of the language barrier, and to update in real time, so that the latest information can be always maintained. In the future, we want to develop an app that can be commercialized by using a character in the path to promote it.

A pressure sore wound is often extensive or complicated by local infection involving adjacent soft tissue and bone. In this case, a regional flap after simple debridement is not adequate. Here, we present a case of an extensive pressure sore in the sacral area with deep tissue infection. A 43-year-old female patient with a complicated sore with deep tissue infection had a presacral abscess, an iliopsoas abscess, and an epidural abscess in the lumbar spine. After a multidisciplinary approach performed in stages, the infection had subsided and removal of the devitalized tissue was possible. The large soft tissue defect with significant depth was reconstructed with a free latissimus dorsi musculocutaneous flap, which was expected to act as a local barrier from vertical infection and provide tensionless skin coverage upon hip flexion. The extensive sacral sore was treated effectively without complication, and the deep tissue infection completely resolved. There was no evidence of donor site morbidity, and wheelchair ambulation was possible by a month after surgery.

Millions of scrap tires are discarded annually in Turkey. The bulk of which are currently landfilled or stockpiled. These tires consume valuable landfill space or if improperly disposed, create a fire hazard and provide a prolific breeding ground for rats and mosquitoes. Used tires pose both a serious public and environmental health problem which means that economically feasible alternatives for scrap tire disposal must be found. Some of the current uses of scrap tires are tire-derived fuel, creating barrier reefs and as an asphalt additive in the form of crumb rubber. However, there is a much need for the development of additional uses for scrap tires. One development the creation of shreds from scrap tires that are coarse grained, free draining and have a low compacted density thus offering significant advantages for use as lightweight subgrade fill and backfill material. This paper reports a comprehensive laboratory study that was performed to evaluate the use of a shredded tire-sand mixture as a backfill material in trench conditions. A steel frame test tank with glass walls was created to replicate a classical trench section in field conditions. The results of the test demonstrated that shredded tires mixed with sand have a definite potential to be effectively used as backfill material for buried pipe installations.

Y$_2$O$_3$ films were pulsed laser deposited on cube textured Ni and Ni-W substrates to be used as a single buffer layer of YBCO coated conductor. Initial deposition of $Y_2$O$_3$ films was performed in a reducing atmosphere, and subsequent deposition was done in the base pressure of the chamber and oxygen atmosphere. The $Y_2$O$_3$ films have a strong cube texture (The full width at half maximum of the ø-scan of $Y_2$O$_3$ was 8.4 which was the same as that of metal substrate) and smooth crack-free microstructure. The biaxially textured YBCO films (The full width at half maximum of the ø-scan was 10.2) pulsed laser deposited on the $Y_2$O$_3$/metal exhibited Tc(R=0) of 86.5K and Jc of 0.7 MA/cm2 at 77K in self field, representing that the $Y_2$O$_3$ single buffer layer is an efficient diffusion barrier of Ni and thus very promising for the achievement of high-Jc YBCO coated conductor.

The study aims to identify the existing problems and suggests the implication for the planning of emergency shelter in terms of users' habitability. The results of the study show that the concept of shelters for disaster victims need to set up and be distinctively defined as emergency phase and temporary residency phase. In emergency phase, the various types of buildings and facilities should be considered as temporary shelters for disaster victims such as transitional shelters including the public facilities. Based on the results of the critical review, this research proposed an analytic framework emphasizing habitability for disaster victims including vulnerable people such as the disabled, the aged, women and children. The framework is composed of four dimensions: safety, health, convenience and comfortability. The manual guidelines for emergency shelters should reflect the barrier-free design or universal design for various types of disaster victims considering habitability to provide the positive opportunity and future hope for restoration after disaster. This research can be a basis for the planning and application of temporary shelters for disaster victims.
