8 X 10$^{6}$(viable cells/ml) of maximum cell density and 9000(IU/ml) of $\gamma$-IFN production were obtained at 55(ml/hr) of a perfusion rate by cultivating HSF cells using a moving membrane aeration bioreactor. This system proves to be an efficient culture process by maintaning 90% of viable cells during the whole cultivation periods. The metabolic molar quotient of glucose to lactate was 0.81 for overall ranges of glucose consumed while the evolution of ammonia was not linearly related to the consumption of glutamine. Low molar conversion ratio was observed in low consumptions of glutamine and high molar conversion ratio in high comsumptions. It also shows that the glutamolysis plays important role in the steady state conditions by evolving larger quantities of ammonia than lactate. At the above of 50 rpm, which is the optimum agitation speed for this bioreactor, the cell growth was severely affected while the IFN production was less decrea- sed, maintaing 1.5 X 10$^{-3}$(IU/cell/day) specific IFN production rate. The cumulatvie $\gamma$-IFN production was 7.2 X 10$^{8}$(IU) for 70 days of the cultivation, which yields 1 X 10$^{7}$ (IU/day) of IFN production rate. Therefore, a commercial production of $\gamma$-IFN by this culture process can be achievable by maintaining the above IFN productivity in a scaled-up culture system.

Many Asian countries are suffered from various problems on water, which include the need for increased access to improves water supplies and sanitation through investments in infrastructure and capacity building, the balances water management system between development and ecosystem, and the need to reduce the human populations'vulnerability to water-related disasters, in particular, from climate variability and evolution. Decison makers are the most influential people in policy making and solving global water problems is central issue in eradicating poverty and achieving sustainable development (MDG). They across the world form an integral part of the architecture of national or regional governance. Their role covers a range of decision-making processes including passing legislation, scrutinizing government policy, and representing citizen through the election. We must ensure that these quiet but important issues get the political space, financial priority and public attention they deserve. Regional bodies such as the EU have also enacted legislation which introduces rules on water quality and other enforceable mattera across state boundaries. With this growing body of laws and policies on water issues, the role of decision makers is growing. Recognizing this role, decison makers' platform is essential to provide an opportunity to discuss crucial water issues in each country or region and for the purpose "2010 Parliaments for Water in Asia" has planned and organized to investigate our common issues and goals. During the meeting, we have an opportunity to observe water policy of Bangladesh, Bhutan, China, Mongolia, New Zealand and the Philippines and share the views on what needs to be done to move forward by decision makers for the future of water. In conclusion, the process of developing the decision makers' platform in each region would be ultimately essential point to increase the awareness of the developed and developing countries' roles, knowledge to clarify roles and responsibilities of each stake holders and finally be a major actor for resolving not only water challenges also issues of human settlements.

The application of the theoretical model to real assembly lines has been one of the biggest challenges for researchers and industrial engineers. There should be some realistic approach to achieve the conflicting objectives on real systems. Therefore, in this paper, a model is developed to synchronize a real system (A discrete event simulation model) with a theoretical model (An optimization model). This synchronization will enable the realistic optimization of systems. A job assignment model of the assembly line is formulated for the evaluation of proposed realistic optimization to achieve multiple conflicting objectives. The objectives, fluctuation in cycle time, throughput, labor cost, energy cost, teamwork and deviation in the skill level of operators have been modeled mathematically. To solve the formulated mathematical model, a multi-objective simulation integrated hybrid genetic algorithm (MO-SHGA) is proposed. In MO-SHGA each individual in each population acts as an input scenario of simulation. Also, it is very difficult to assign weights to the objective function in the traditional multi-objective GA because of pareto fronts. Therefore, we have proposed a probabilistic based linearization and multi-objective to single objective conversion method at population evolution phase. The performance of MO-SHGA is evaluated with the standard multi-objective genetic algorithm (MO-GA) with both deterministic and stochastic data settings. A case study of the goalkeeping gloves assembly line is also presented as a numerical example which is solved using MO-SHGA and MO-GA. The proposed research is useful for the development of synchronized human based assembly lines for real time monitoring, optimization, and control.

The residential environment is a place which reflects the gradual evolution of human consciousness because it is a cultural space the term, 'houses' is not relevant in this context as it literally means 'contains'. The long history of human living habits cannot be 'contained' within a space, but can be 'expressed' by a space and by the way the space is used. Furthermore, due to the way it is typically constructed, the basic characteristics of the house usually cannot be rapidly changed to accommodate new habits. However, recent changes that have taken place to the characteristics of the traditional master room suggest that traditional societal values associated with patriarchy have diminished. The current trend where priority is given to children's education also affects such a change. Existing researches related to the master room is confined to the behavioral use of the space and the composition of the physical space, while research on the master room its plane type has not been carried out. Therefore, in this study, apartment model houses are selected, and are classified according to the types of master room. An analysis is then carried out of the master room based on the occupants' requirements in terms of consciousness. Any planning modifications where required are then suggested. This research comprises the followings stages. First, an examination is carried out of existing research on the master room in order to understand its background and spatial components. A definitiones of related terms is also provided. Second, an analysis is carried out of the model houses exhibited at Suwan District, examining the typical standard that has been selected for the master room. Third, an analysis is conducted of the topics and questions to be selected for a questionnaire. Fourth, an analysis is carried out of the consciousness, satisfaction and requirements of the residents, as respondents in the questionnaire, related to the master room. and Research is then conducted of the architectural methods for planning the master room. Finally, future countermeasures for planning the master room are described based on the above analysis and research findings.

This study developed and proposed a lesson plan for the area of “Human development and family relationship”in secondary home economics curriculum. In current educational practice in secondary home economics curriculum, the employed goal and the nature of home economics are neither stated specifically nor closely interrelated. This problem has led us not being able to achieve pursuing goal of home economics education and to employ appropriate teaching methods. In view of this situation, the purpose of this study was to propose a lesson plan reflecting the contents and teaching methods to overcome difficulties and inefficiency in the current practice of secondary home economics education. The theoretical background of the lesson plan was based on the Marjorie M. Brown’s philosophy of home economics which can be summerized as follows: 1. The goal of home economics is to help individuals and families to become autonomous in their own family life and to be more capable of interacting with others in behalf of well-being of the family and of social evolution toward a free society. 2. The characteristics of home economics is conceptualized as practical science and personal service profession. 3. the nature of problems which home economics should deal with is perennial and practial. 4. Practial reasoning composed of historical understanding, critical action, and reflective thinking is appropriate for the previously mentioned goal and characteristics of home economics and for dealing with perennial practial problems. The lesson plan was proposed for one of perennial problem, “How should we understand, create, and maintain our family culture\ulcorner”by employing practial reasoning and teaching models such as “role play”and “classroom meeting.”

우리나라 장애인복지의 발전과정은 대체로 4기로 구분할 수 있다. 제1기는 1981년 이전으로 장애인을 한낱 자선의 대상으로만 보았던 시절이고, 제2기(1981~1988)는 "장애인복지법"제정으로 장애인복지 이념의 등장과 태동시기에 해당하며, 제3기(1989~2006)는 장애인복지제도의 틀을 정비하고 복지서비스 확대를 도모하던 시기라고 할 것이며, 제4기(2007~현재)는 장애인차별금지법 제정 등으로 장애인 인권 및 복지 보장의 확대전환기라 할 수 있다. 특히 우리나라에 있어서 장애인복지 관련 법제는 2007년이 새로운 역사적 이정표를 세운 해라고 할 것이다. 이 해에 장애인계의 오랜 숙원이었던 "장애인차별금지 및 권리구제 등에 관한 법률"이 제정되었고, 기존의 "특수교육진흥법"이 폐지되면서 새로운 "장애인 등에 대한 특수교육법"으로 대체 입법 제정되었으며, "장애인복지법"이 장애인복지 패러다임 변화를 수용하는 내용으로 전부개정되는 등 법제도상의 괄목할만한 성과를 이룩하였던 것이다. 여기서는 우리나라 현대사에 있어서의 장애인복지 수준을 가늠할 수 있는 관련 법제도의 입법화과정과 현행 법제의 체계를 살펴보고, 현행 법제의 주요내용과 개선과제를 논함으로써 향후 우리나라 장애인복지 관련 법제의 발전방향을 제시해보고자 한다.
