  • During the last decades several proposals have been made in literature to use predictive control for inverter control-especially in electrical drives. These algorithms are completely different to the recursive but linear predictive algorithms known from information theory, where closed mathematical equations are used (e.g. Kalman-filters). Only few of the presented schemes have been realized in industrial applications so far. After some further progress, however, the advantage of predictive algorithms might lead to an increased number of industrial implementations in the future. Besides the common basic idea - to use the well-known but strongly non-linear behaviour of inverters to precalculate the best switching times - there are many differences in the details of these proposals. This contribution shows similarities and differences and attempts to design a 'family tree' of predictive control algorithms. This might grow to a first step to a theoretical approach to deal with predictive control schemes in a more generalised way.

  • The purpose of the Environment Design (ED) for Main Control Room (MCR) of Nuclear Power Plant (NPP) is to provide and create an optimal working space to be free from physical, physiological and mental stress as well as environmental discomfort, based on the previous environment design experiences and to recommend the best ED including the color, the lighting and the interior design. Environment Design consists of three main areas: Human factor engineering design, Interior design with color design, and Lighting design. These design areas have been interactively cooperated in a way that each design specialist would share the objectives and concepts of the Environment Design for MCR. The specialists for Human Factors Engineering design had a corporative role in such a way to provide the guidelines for MCR design suitability of Interior and Lighting design considering the Human System Interface (HSI) safety concerns. This paper describes fruitful efforts to create the best fit for MCR ED among several design proposals with the design recommendations, impacts, and contributions to NPP environment.

  • This paper is aimed at the development of a theoretical framework that addresses practical applications of generative design system that have been observed in architectural practice. Existing theoretical frameworks are not aimed at addressing this specific use of parametric tools but do provide a set of key themes. Based on these themes a generative design system is presented here as a means for tackling architectural design development tasks. This is then used in order to examine a case study; the generative design system tasks involved in the design development and documentation of the Olympic Stadium in Germany. The findings from this examination are used to discuss proposals and implications for a practical framework for generative design in architecture.

  • The word "soundscape" proposed by Canadian composer R. Murray Schafer is now became very popular. So various soundscape design based on soundscape idea are carried on worldwide for acoustic ecology. Also in Korea, several soundscape design were made for the public spaces such as river, park and bridge but, basic concept behind soundscape design was not reflected and studied sufficiently. In that sense, this study aims to arrange the concept of soundscape design process and to review the design proposals of Gwangju River. In this process, the reproduction concept of soundscape, natural sound, light with sound, cultural and historical sound and etc. were classified and the final design was proposed to recover the natural environment and harmonize the sound with surroundings as creative soundscape.

  • The Cases of advanced nations which have advanced welfare policy, they have headed for the deinstitutionalization and the protection of the local society. So they have expanded and improved the various policies and welfare facilities to be able to keep daily life on the base of local area. Many problems have been caused by rising the average life span of the elderly in Korea now. Under the tendency, there have been many alternative proposals to solve the problems. One of those proposals, the deinstitutionalization theory that is rated the ideal way, is the community-based care than the care in facilities for the elderly. It shows that the most ideal facility for the care is Daycare center and that it matters the system of spatial construction and standard of the facilities. Under the undetailed Korean standard of facility design, it is very important that system of spatial construction to correspond to the needs of the users and standard of the facilities are prepared from the point of view of the standard design of the domestic facilities for the elderly. The study of the book grasps the regional present situation of the domestic Daycare center and surveys the tendency of the stay and features of occupation of the user there through some case, and aims to have a thorough grip of the spatial scale by the user's behavior. It is to utilize for a proposal for preparation of the space scale, and an institution standard corresponding to user's needs in a Daycare center.

  • This article attempts to propose the control planning of townscape color around the historic and cultural heritages. The streets and roads of historic conservation and the changing perspectives to which it gives rise in Stockholm has changed dramatically during this century. New development or changes to existing buildings should be carried out in a way which acknowledges its surroundings and is a good neighbour, both in the cultural and social sense that makes good color design sense. There are many examples of townscape color, but the conservative and the historical streets and roads in the whole of the Stockholm city should benefit from careful design of the environment. To achieve this purposes, some strategies of case study of several streets and roads are reviewed; designing color context to relate to urban architectural design proposals of specific sites of cultural heritages are explored. In all new developments the scale of new buildings and the material finishes and colors used should respect the character of their surroundings and have due regard to the setting of any listed building. Streetscape color of visual assessment proposals should aim to help assimilate the development into the local scene. Important streets and roads should also include color townscape.

  • Owing to the mass-housing policies of high-density and high-rise, the residential environments in Korea have come to be uniform and monotonous. Nevertheless, the design competitions introduced for th first time in 1980s have played significant roles in developing the fresh ideas and concepts in housing design. It is important to review the ideas played proposed in competitions until now in order to spread them into other housing developments. In this context, this study classified the types of unit plan and analyzed their design characteristics in the proposals of housing design competitions in 1990s.

  • Purpose: The South African government is determined in alleviating poverty while encouraging job creation and protecting the disposable incomes of poor households. This article looks at the challenges that are facing the South African Social Security system and argues that the provision of income security is amongst the most practical expressions of a nation's cohesion and values. Research Design, Data and Methodology: There are seven proposals in the Social Security and Retirement Reform and these proposals are based on the following two principal objectives of the government, that is, to ensure a basic standard of living and to prevent destitution in old age or in circumstances of unemployment or incapacity partly or wholly through redistributive measures, and to encourage savings to provide for the replacement of income on retirement, disablement or death through long-term insurance arrangements. Results: This article evaluates these seven proposals, state old age pension, wage subsidy, mandatory participation in a national social security system for all, mandatory participation in private occupational or individual retirement funds, Voluntary additional contributions to occupational or individual retirement funds, reform of the governance and regulation of the retirement funding industry and reform of the tax system. Conclusion: This article concludes that the population size of South Africa has increased significantly to 51, 8 million in 2011 and therefore the time is right for bold new steps in improving income security of the poor and strengthening the fabric of social solidarity that binds all South Africans together.
