The fast and competitive urbanization has accelerated unbalanced land utilization and housing, thereby producing large number of decaying areas and socially disadvantaged population, while generally promoted citizen's quality of life. Since rental housing policy, therefore, has emerged as a major important issue to solve these ever increasing problems, new concepts in leading examples need to be explored to stimulate creative ideas for future housing improvement. The purpose of this research is to extract successful factors of a leading rental housing 'Manhattan Plaza' in New York city, expecting useful implications for housing improvement in Korea. Field visit and in-depth interview for data collection and qualitative approach for analysis were carried out. As results, its successful sustainability and fame were found to be attributable to following concepts, such as, socially integrative mix of diverse residents, residents' participation in management, privacy respect administration, considerate planning and design features of physical environment. The latter, especially, were prominent in peripheral spaces, indoor and outdoor community spaces, and private spaces. Based on the results, suggestions were made for future Korean rental housing development.

Recently, interest in fair tourism and demand for this service has been steadily increasing. This study examined the tourists' perceptions of their fair tourism experiences. Phenomenological method was adopted as a qualitative research approach. Participants were nine adults who were interviewed in depth on their experiences of fair tourism. Data analysis led to the emergence of seven categories (sharing and volunteerism, environment and animal protection, tourism created together, communication and relationship, from consumption to experience, ethicality and fairness, contemplating life) and 21 subcategories. This research was a significant step in providing options to explore the improvement of ethical-tourism and may have implications for the future development of tourism. This study also has various implications for tour operators, consumers, and government. In future all stakeholders should make efforts to establish the tour culture which encourages consumers to consider the ethicality and fairness of their choices as tourists.

Applying intuitive learning method on engineering education, especially for the mechanical engineering, is hardly found from the previous case studies and is not easily proved its beneficial verification. Verbal repetition is also rarely used to investigate its positive effects on educational methodology for both science and engineering disciplines. To prove the education effects of these two methods; we used intuitive thinking time period at the beginning of each lecture and let students repeat the concepts and the equations verbally. These two methods were related to the subjects of each lecture, and were used for students to try to draw engineering thinking from natural phenomena that they could easily experience in daily life. The methods could help them to memorize theoretical ideas. We investigated the effects of intuition and verbal repetition methods by comparing the scores of final exam with those of midterm exam. The results revealed significant improvement; 77.6% of the students achieved higher score in their final exam compared to midterm exam. We plan to investigate qualitative contributions of intuition and verbal repetition methods to the students' achievement for the further research.

Environmental furniture comprises an independent design branch as distinguished from he design of street furniture. Environmental furniture helps people enjoy outdoor relaxation and cultural activities by creating convenient facilities and plays a part as the medium connecting environment and living. As a tool effecting all outdoor living conditions including home and public environment, it helps people lead a convenient and safe outdoor life. It is an important element that contributes to the image of outdoor scenery. Therefore, the design of environmental furniture should : 1)consider environment including 3R(Recycle, Reuse and Reduce) which makes harmony with nature without destroying it. 2)seek qualitative improvement by using environmental friendly materials and continuously developing new materials. 3)be assisted by the administrative support from the government to make the environmental furniture design an integral part of the city plan. The quality of a city environment will be greatly improved when people's interest in and their changed view towards environmental furniture is effected.

This paper presents a derating design approach for reliability improvement of a regulator IC. The IC is usually used in SMPS. The main failure mechanism of interest is voltage drop due to the package delamination mainly caused by two stresses, i.e. temperature and current. The lifetime under stresses is modeled as a function of stresses and time using accelerating life testings. Quantitative and qualitative variation in lifetime according to stress variations are investigated using the modeled lifetime. Stress levels would be determined to achieve required reliability levels in the aspect of derating design for reliability.

The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. Particularly, architectural information is generated and managed through the life cycle of a building, from conceptual design stage to the construction and maintenance. A Building Information Model (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. BIM technology accomplished quantitative development being utilized in various disciplines. However, it is necessary to develop environment and requirement for qualitative improvement of BIM based project. Particularly, requirement is very important for architectural design evaluations. The purpose of this study is to develop and apply of quality control requirement for improving the quality of architectural design in open BIM environments. To achieve this purpose, the authors have investigated case study for open BIM data quality control (software, guideline and application case) and classified quality control targets according to physical/logical quality and data quality. In addition, the authors have defined open BIM based quality control process and developed quality control requirements. Finally, the authors have developed rule based quality check system using requirements for efficient quality control based on open BIM.
