The purpose of this study is to provide the guideline of the outdoor space of residential land development district for children's outdoor activites. This study was accomplished by the valuation of the physical environment of 5 residential land development districts, the analyzation of behavioral mapping about children's outdoor activities, and the analyzation of satisfaction and the consciousness of 190 residents(parents) & 230 children. Especially, outdoor spaces were divided into 6 parts (play space, education facility, commercial facility, green space, and empty space & parking lot). And than, 6 outdoor spaces were valuated about the physical characters such as accessibility, network, safety, variety, functional, natural elements. Also, the survey for residents and children's consciousness were used the Likert scale. According to the result of this study, many parts of the housing area were not good for children's activities, and resident's satisfaction was low. In the sample areas, negative factors were car and motorcycle. And many residents were pointed out the lack of natural elements, variety, and safety of outdoor space in dwelling area. Finally, this study suggested the guideline children's activities based on the result of analyzation of valuation, behavioral mapping, and survey.

The purpose of this research is to provide basic data for the promotion strategy to activate modular construction system as residential facilities, through a study on the architectural planning, institutions and policies and research on connection details, for the use as residential facilities of the modular construction that is not actively supplied for the general residential facilities. As a result, I suggest sample model plan of domestic and foreign case analysis and characteristic of modular construction and practical application of modular construction for Residential Facilities. Owing to many advantages including short construction period structural stability and economic benefits, modular construction is expected to play a role as residential alternative of socially controversial affordable housing and weekend homes, and potential housing shortage after reunification; and to contribute to the development of design automation and industrialized constructions. Though Korea is still lacking development of the system that meets the domestic context, if supported by ongoing researches on the development of construction methods, materials and details, the settlement of appropriate modular residential facilities to suit the national situation will serve a possible alternative solution for many housing and environmental problems.

Recently, as the concern over environmental problem has been serious all over the world, carbon has become a key issue to mitigate the problem. In the field of Architecture, various sustainable assessment systems and LCCO2 assessment strategies have been developed, guiding low carbon building while planning. However, assessment system for low carbon neighborhood, which can be more efficient strategy, is still in the stage of research. In this paper, as a research for low carbon assessment system and planning guideline for neighborhood, scope meeting domestic condition has been set and sustainable assessment system for neighborhood, which is similar to low carbon concept, have been compared. LEED-Neighborhood Development, BREEAM-Communities, CASBEE-Urban Development, and GBCC-Apartment Houses were used for comparison. As a result, it is found that those systems has many differences in judging system, aggregating method, scope of evaluation, and relations with a building assessment system. The concern about carbon is not insufficient yet. Finally, assessment system for low carbon neighborhood, which is not only for establishing the plan, but also for giving guideline at the very first state of the plan, should be developed as fast as passible. With the result of this paper, establishment of assessment criteria and the way to measure quantitative $CO_2$ should be studied forward.

This study aims at analyzing the development status of surroundings of natural environment conservation areas and securing an adequate distance from development activities to conserve natural environment conservation areas efficiently or developing an improvement plan for setting conservation areas. Findings from the study shows that 1) rather than simply designating a legal natural environment conservation area, a conceptual scope approach of a "core area", "buffer area", and "transition area" such as in zoning of a "biosphere reserve" by UNESCO is recommended; 2) when setting an adequate range in a natural environment conservation area, it should be set by fully considering locational situation and the regional and environmental features of surroundings rather than setting a certain distance uniformly; 3) instead of designating wetlands only as a conservation area, entry and exit areas should be also included as buffer areas and in the case of wild animals, not only habitats but also feeding areas should be designated as conservation areas; and 4) an adequate horizontal separation space is important in the case of ground development, but for natural resources related to subterranean water and geological situation such as wetlands, an adequate vertical separation space should be fully considered.

As globalization proceeds, transnational property development is increasing. Vietnam has began to experience a serious housing shortage throughout the urbanization process and they try to solve this housing problem in the city by development of New Town with an excellent technique. Of these, New city, Phu My Hung (PMH) is known as a very successful example. Therefore, this study researched 145 plan of 15 Apartment complexes which were completed after 2008 to analyse the plan characteristic of internal-external of Apartment in PMH New city in Ho Chi Minh City which effected the housing development in Vietnam. We collected the data from Internet and researched the characteristic of complex and an individual unit by visiting 6 Apartment complexes directly on Aug, 2014. In PMH, apartment has pattern of Mixed-use Apartment. There are stores on the 1st ad 2nd floor and consisted of 2 or 3 small complexes. They secure enough Green Space and Community Space and control visitor access for the safety of residents. Inside space organization is mainly consisted of 3LDK+2BATH and Public space and Private space is placed separately. Also, placed the Kitchen independently and it is quiet interesting that the entrance entry into the house directly from the external space.

The magnetic polishing is the useful method to finish some machinery fabrications by using magnetic power. This method is one of the precision polishing techniques and has an aim for clean technology in the transportation of the pure gas in the clean pipes. The magnetic abrasive polishing method is not so common in the field of machine that it is not known to widely. There are only few researchers in this field because of non-effectiveness of magnetic abrasive. Therefore, in this paper deals with development of the magnetic abrasive using Ba-Ferrite. In this development, abrasive grain GC and CBN has been made by using the resin bond fabricated at low temperature. And magnetic abrasive powder was fabricated from the Ba-Ferrite which was crushed into 200 mesh. The XRD analysis result shows that only GC, CBN and Ba-Ferrite crystal peaks were detected, explaining that resin bond was not any more to contribute chemical reaction. From SEM analysis, we found that GC, CBN abrasive and Ba-Ferrite were strongly bonding with each other.

The accurate prediction of the ship wave resistance is very important to design ships which operate satisfactorily in a wave environment. Thus, work should continue on development and validation of methods to compute ship wave patterns and wave resistance. Research efforts to improve the prediction of ship waves and wavemaking resistance are categorized in two major areas. First is the development of higher-order theories to take account of the nonlinear effect of the free surface condition and improved analytical treatment of the body boundary condition. Second is the development of direct numerical methods aimed at solving body and free-surface boundary conditions as accurately as possible. A new formulation of the slender body theory for a ship with constant speed is developed by Maruo. It is quite different from the existing slender ship theory by Vossers, Maruo and Tuck. It may be regarded as a substitute for the Neumann-Kelvin approximation. In present work, the method of asymptotic expansion of the Kelvin source is applied to obtain a new wave resistance formulation in fluid of finite depth. It takes a simple form than existing theory.

The objective of this study is to investigate the influence of powder shape and densification mechanism on the microstructure and mechanical properties of Ti-6Al-4V components. BE powders are uniaxially and isostatically pressed, and PA ones are injection molded because of their high strengths. The isostatically compacted samples exhibit a density of 80%, which is higher than those of other samples, because hydrostatic compression can lead to higher strain hardening. Owing to the higher green density, the density of BE-CS (97%) is found to be as high as that of other samples (BE-DS (95%) and P-S (94%)). Furthermore, we have found that BE powders can be consolidated by sintering densification and chemical homogenization, whereas PA ones can be consolidated only by simple densification. After sintering, BE-CS and P-S are hot isostatically pressed and BE-DS is hot forged to remove residual pores in the sintered samples. Apparent microstructural evolution is not observed in BE-CSH and P-SH. Moreover, BE-DSF exhibits significantly fine grains and high density of low-angle grain boundaries. Thus, these microstructures provide Ti-6Al-4V components with enhanced mechanical properties (tensile strength of 1179 MPa).

Climate change and global warming are the biggest challenges of the current generation. Every industry has contributed to the climate change and global warming. Even the apparel industry cannot avoid the criticism regarding fast fashion and its contribution to the pollution. The transition to the decarbonized economy is in progress. All aspects of business functions are influenced by climate change. Sustainable development and climate change are closely linked, and business plays the key role in addressing and finding solutions to the challenges of climate change. Luxury brands are the trendsetters and tastemakers. They are the leaders in the fashion industry and therefore responsible for improving on sustainability as well. Even luxury business cannot avoid environmental issues. The relation between luxury and sustainability is explored with the Burberry case based on the Triple Bottom Line (TBL) framework. There are various ways for luxury brands to excel in sustainability and affect other companies' practices. The companies can incorporate the concept of sustainability in their brand stories as part of the branding process. They can also improve demand planning accuracy and produce upcycled goods. Centering on Burberry's case, this paper aims to explore the current sustainable practices of luxury business along with its future direction toward sustainable development. Its contribution and directions for both researchers and business practitioners are discussed.

The economic development of most countries in the world has negatively impacted fossil energy resources. Fossil energy sources such as petroleum and coal are increasingly depleted. When energy sources are exhausted, renewable energy sources are growing strongly. Renewable energy development can help to replace diminishing fossil fuels. Furthermore, the usage of renewable energy can contribute to a green economy and sustainable development by protecting the environment. Solar power on the roof is one of the many renewable energy sources available. But at present, the investment in roof voltage systems has not developed strongly in Vietnam. This paper uses the SEM model to evaluate the factors affecting investment in rooftop solar power in some provinces of Vietnam. The article uses the household interview method. The article has given 8 factors affecting the decision to invest in rooftop solar power for households. Research results show that most of the factor variables have a positive impact on the decision to invest in rooftop solar power. Based on assessing the factors affecting the decision to invest in rooftop solar power, the article will provide conclusions and policy suggestions to increase investment in rooftop solar power in Vietnam.
