Recycled polypropylene (RPP) - Wood Saw Dust (WSD) composites with and without acetylation of filler were produced at different filler loading (15%, 25%, 35% and 45% w/w) and filler size (300, 212 and $100{\mu}m$). The RPP-WSD was compounded using a Haake Rheodrive 500 twin screw compounder at $190^{\circ}C$ at 8 MPa for 30 minutes. The mechanical properties and water absorption properties of modified and unmodified WSD-PP composites were investigated. Acetylation of WSD improved the mechanical and water absorption characteristic of composites. The decrease of filler size (300 to $100{\mu}m$) of the unmodified and acetylated WSD showed increase of tensile strength and impact properties. The composites exhibited higher tensile modulus properties as the filler loading increased (15% to 45%). However tensile strength, elongation at break and impact strength showed the opposite phenomenon. Water absorption increased as the mesh number and filler loading increased. With acetylation, lower moisture absorption was observed as compared to unmodified WSD. The failure mechanism from impact fracture of the filler-matrix interface with and without acetylation was analyzed using Scanning Electron Microscope (SEM).

The purpose of this study is to minimize physical obstacles for handicapped students in university dormitories. To carry out this study, we have surveyed 10 Universities in Korea. First we have studied the law and the theory of architectural planning and design guides those are related with handicapped people. And it was surveyed the existing state of the dormitories facilities and made a checklist. And the satisfaction about the facilities was questioned to the handicapped students who used those buildings. It is concluded that most of the universities which we have surveyed were equipped with good facilities for the general students but don't have regards for handicapped people at that time. As the result of the rate of the satisfaction, they are satisfied those facilities generally. As you can see the result of this research, the facilities in University are not very good for handicapped people in many points. So that kind of many facilities must be taken into consideration for handicapped people in the stage of architectural programming in the process of designing the dormitory building.

This study emphasizes a new senior housing type which can provide individual housing units and common facilities for retirees, particularly who will be retired from universities. It is called a university-based retirement community. This study conducted a questionnaire survey to investigate future residents' needs for architectural environments that included housing types, common facility features, and proximity, and also development methods in response to the university involvement levels. The survey questionnaire was administered in one national university in Korea. A total of 214 responses were valid for statistical analyses. Major findings are as follows: Over 65% of the respondents were willing to live in the university-based retirement community. Regarding the location of the community, they responded the community would not need to be located on campus. Preferred common facilities in the UBRC were indoor fitness centers, the shuttle bus stops connecting to the adjacent areas, and bath and sauna facilities. The respondents emphasized university's contribution toward offering educational programs for UBRC residents. Lastly, their responses to the university role and involvement in the development and construction process were identified. This study results are expected to provide essential information for facilitating the Korean model of university-based retirement communities in the future.

Purpose: The research is focused on the 25th King Cheoljong's mother's parents' traditional House in Ganghwa-do, for finding out how the surrounding natural environment was considered with Pungsu, a traditional ecological architectural science in case of site selection and architectural planning by the relative of royal family of Joseon period. Method: The study is processed as follows. Human Environment of the region where the house is located, is analyzed in chapter 2. Feature of mountain expressed as dragon and four important hills of the house are analyzed in chapter 3, Highly regarded factors for site selection by the scholar of the Realist School of Confucianism such as wind environment, the front and back of the Hyunmubong and building orientation are analyzed in chapter 4. Finally Pungsu applied in architectural space is analyzed in chapter 5. Result: The house considered Pungsu to some extent, but it shows the appearance contrary to the Pungsu in a certain part in order to show authority and proud as the house of the relatives of the King. It can be seen that the degree of application of Pungsu may be different depending on the will of the building owner.

The purpose of this study is to minimize physical obstacles, to propose how we can improve them, and to get the basic information to establish the welfare policy for handicapped students in the university dormitory by studying and analyzing actual conditions of existing facilities and its improving transition which provide most important living accommodation to university students. To carry out this study, they have been surveyed 10 Universities in Korea as a case study which 1 university in Seoul & Kyunggi province, 2 universities in Chungchung province, 5 universities in Jeolla province and 2 universities in Kyungsang province. And they have been studied in relation to the law, theory of the architectural planning & design, and general consideration about handicapped people. As a result the checklist about the facilities was made. The term of survey was in August 2001 and in September 2004. It is concluded that most of universities which have been surveyed were equipped with good facilities for general students without regards for handicapped people at that time. As you can see the result of this research, the facilities of boarding house for handicapped people are very scanty in many universities.

Paris hasn't experienced such excitement since the huge changes brought about by Baron Haussmann in the 19th century. Paris Rive Gauche project, started in 1991, is the largest urban project in city ever since, it represents about 1% of Paris territory. It takes place on a workshops, factories and warehouses area that prospered along the Seine river and the railways in the 19th century. Originally planned as a business quarter, Paris Rive Gauche, developed by SEMAPA for the City of Paris, fosters urban diversity through housing, offices, public facilities, shops, creating a stimulating neighbourhood where 18,000 residents, 30,000 students as well as 60,000 employees will soon croth paths. This project's main principles are urban and social diversity, deployment of public facilites, the development of new university campus inside the city, promotion of industrial patrimony and connecting the old 13th distict to the river and the opposite side. Half of the project is going to be built on a concrete slab that covers the railway tracks which is one of the major performances of this long-term project. This concrete slab represents the new level of the City, about 6 to 8 meters above the railway tracks. We distinguish three families of buildings on the cover : Classic buildings; Bridges buildings and Connection buildings, these last guarantee the linkage between old and new level of the City.

In recent days, there are many researches of wireless LAN services as the communication environment of wireless LAN are so improved that a lot of services are available in wireless environments. The frequency of the wireless LAN is a general resource that can be used to everyone without any permission. Many technologies using this ISM (Industry Science Medical) frequency band are developed fast and widely. But, as many devices use the same frequency band at th same time, the service quality is degraded and the speed of the service rate id degraded by the result of the interference. For overcome this problem, we must provide the new technology of the mobile devices and a new cell design scheme for obtaining maximum throughput that considering the wireless environments effectively. In this paper, we explain the main technology at the IEEE 802.11n environments and proposes the optimal cell design and reference model for gaining maximum performance to many mobile devices at the same time by investigating real environment testing results.
