As the increasing integrity of VLSI, the BIST(Built-In Self Test) is used as an effective method to test chips. Generally the pseudo-random test pattern generation is used for BIST. But it requires too many test patterns when there exist random resistant faults. Therefore we propose a mixed test scheme which applies to the circuit under test, a deterministic test sequence followed by a pseudo-random one. This scheme allows the maximum fault coverage detection to be achieved, furthermore the silicon area overhead of the mixed hardware generator can be reduced.

Water disasters such as flash floods and inundation caused by localized heavy rainfall in urban areas have a large impact on climate change but are also closely related to the increase in impervious areas as pointed out in domestic and international studies. It is difficult to secure natural green areas in urban areas that have already been developed. So, urban regeneration can be expected using water management optimized with technologies to secure infiltration and storage capacity such as Low-Impact Development technology. In this study, the water cycle improvement ability was confirmed by applying the LID technology within the district unit plan of the environmentally friendly village, and the economic feasibility of LID application was analyzed by estimating the costs and benefits of installing the facilities. The site was planned to conserve sufficient green and plans for securing the watershed infiltration and storage capacity were formulated with the application of additional LID technology, such as infiltration trenches, rain barrels and permeable pavements. The LID design method applicable to the site was established, and the water balance of the watershed was analyzed through simulations of the SWMM model. The water circulation improvement effect was confirmed through the water balance analysis, and the cost-benefits were determined according to the estimation method, and the economic analysis was conducted. This study confirms that the investment of LID technology is economically feasible for the hydrological improvement effect of the housing complex.

A new movement in forming community villages for better living standards is becoming popular. In order to sustain a proper community, it is essential to design proper community programs and facilities, which can encourage the proactive participation of residents. In this study, detailed aspects of the Mindlre (Dandelion) community (including formation process and management of the village) are investigated. The Mindlre community is a successful community village in Korea concerned with residents' participation and community activities. The community is located in Sancheong, Gyungsangnamdo province in Korea. The study methods are references, field trips, and interviews with residents. Six areas were surveyed and investigated: the physical environment of the Mindlre community and eco-friendly elements, respondents' background and the motivation to join, residents composition, residents' participation in the formation process of the community, self-management systems and common activities, and residents's life satisfaction. The mindlre Community was founded on Christian religions faith. The primary idea of this village was building a new hope for rural areas without discrimination. The size of the village was expanded with housing for teachers and students who were linked with the Mindlre School (substitution school). When the community was founded, existing shapes of the village were preserved. The village was physically renovated based on the original environment, in addition nature friendly materials and methods were used. The residents were proactively involved in the community through regular meetings, self-regulation, and community worship. Although the survey results should that most residents were highly satisfied with living standards, there seemed to be no clear division between community facilities and private houses. A systematic and detailed space planning technique was required. In addition, various community facilities are required due to the expansion of the community.

Demands for housing has diversified recently due to low birth rate and the growth of aging population. Also, a share of idle houses and obsolete houses over 20 years old is gradually rising. Therefore, there is a need for a sustainable, environment-friendly improvement policy that is in line with a new housing paradigm and avoids full-scale new construction, such as a customized housing renovation plan considering local economic circumstances. Therefore, afforestation system applicable to buildings are assessed positively, but lack objective performance evaluation. Through one-year, long-term monitoring of replicated obsolete buildings that have poor insulation performance, this study calculated monthly average power consumption and analyzed power charges by applying pricing plans before and after the revision of progressive tax in order to examine economic effects expected by applying the afforestation system. In the obsolete buildings, the study showed that monthly average power consumption was reduced by 16.6kWh with 5.2% average reduction rate. Highest reduction was made in July at 11.3%. Aggregate monthly power consumption charges were relatively high in winter before and after the revision of progressive tax. Power charges reduction effect was highest in March when monthly power consumption was reduced to 300kWh level by applying the afforestation system.
