This study examined the perceptions of and attitude towards mixed-race and investigated the factors affecting them and their influence on discriminative behavior. For the study, a survey was conducted with residents residing in Seoul and its suburb. The results showed that the perceptions of and attitudes towards mixed-race, generally, were not so negative and positive in all three types of mixed-race, Caucasian-korean, Asian-korean, and African-korean. In addition, the perceptions of and attitudes toward mixed-race were partly different by the type of mixed race. That is, there were more positive perceptions of and more favorable attitudes towards the Caucasian-korean in Asian-korean and African-korean, and there were less positive perceptions of and less favorable attitudes towards Asian-korean than in African-korean. With regard to the factors affecting the perceptions and attitudes, racism was a factor affecting commonly the perception of and attitudes towards all types of mixed-race. The attitudes towards mixed-race had an influence on the discriminative behavior in all types of mixed-race, and, only in the African-korean, the perception of mixed race affected the discriminative behavior. These results suggest insights for what efforts should be made to improve mixed-race's welfare.

The purposes of the present article are to suggest pragmatism as offering a philosophical paradigm for mixed methods research, to explain the fundamental principles of mixed methodology, and to present examples of research for understanding how to apply it to family studies. Mixed methods research is the class of research where the researcher mixes or combines quantitative and qualitative techniques, methods, approaches, concepts or language into a single study. Mixed methodology has its roots in pragmatism, which is a new philosophical paradigm to criticize the traditional dualism and to endorse eclecticism and pluralism. The present article argues that mixed methods research has the potential to answer a broader and more complete range of research questions, and to provide strong evidence for a conclusion through convergence and corroboration of the qualitative and the quantitative methods.

This study represents that a removal efficiency of organic matters in wastewater is activated by a sludge process using new mixed microbial population. In case of mixed microorganisms, removal rates of suspended solid (SS), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) were over 90 percent under experimental condition, and removal efficiency of organic matters, sludge density index (SDI) and capillary suction time (CST) in mixed population were higher than that in not-mixed microorganism, while total kjeldahl nitrogen (TKN) and total phosphorus (T-P) which indicate a degree of eutrophication were removed easily in both case. From these results, we may propose that an application of the mixed microbial population is useful to treat domestic wastewater including a great deal of organic matters.

The objective of this study was to analyze the space usage and user evaluation of community facility in Apartment. This study was conducted case study and questionnaire survey. Four High rise Mixed-use Apartments in and near seoul built in 2000 and later were chosen for case study and 166 residents were collected for questionnaire survey. The frequency, percentage, mean, One-way ANOVA and Duncan tests were executed through SPSS for Win 12.0 statistics package program. The types of community facilities of High rise Mixed-use Apartments were consisted of sports, child care, study, information sharing, leisure/cultural facilities. Most of the community facilities showed to be similar regardless the subject of High rise Mixed-use Apartments. The usage percentage of community facilities increased since the residents have moved to their current residence of High rise Mixed-use Apartments from their previous residence. The most satisfied facility was sports facilities. The satisfaction of community facilities showed high in general. The satisfaction of community facilities was significant with age and the size of apartment.

The purpose of this study is to determine the impact of the soil load for artificial ground on a building's structural expenses. Three types of soil - 100% soil, soil mixed with 50% perlite, and 100% artificial soil - were used for this study. A one story concrete steel building specific to each soil load was designed, and then, the cost of steel and concrete used for the design was estimated. As the result of this study, the structural expenses in the case of 5:5 mixed soil can be reduced about 17% compare with 100% soil. Using artificial soil, the structural expenses can be cut about 32% compare to 100% soil and about 12% less when 5:5 mixed soil is used. However, considering total expense which includes the structural expense and soil expense, the expense of 5:5 mixed soil have an increase 25% compared with 100% soil. In the artificial soil, the total expense is 45% more expensive than 100% soil and 17% higher when 5:5 mixed soil is used because of the high unit price of artificial soil. This study expected substantial savings in structural cost as the soil-load was lightened. But, savings were significantly reduced because the unit price of the artificial soil is much more expensive than the price of the natural one. Therefore, further research on methods of reducing the unit price of the artificial soil should be conducted in order to extend green space on to artificial ground.

In this study, we have examined potential degradation of MTBE (methy1 tert-butyl ether) by pure culture ENV425 and mixed culture isolated from gasoline contaminated soil using n-butane as the sources of carbon and energy. The results described in this study suggest that MTBE is degraded cometabolically by ENV425 and mixed culture grown n-butane, and the disappearance of TBA after complete degradation of MTBE suggest the further degradation of TBA. Butane and MTBE degradation was completely inhibited by acetylene, which indicated that both substrates were degraded by butane-utilizing bacteria. MTBE was degraded ENV425 and mixed culture grown n-butane, and TBA (tert-butyl alcohol) was produced as product of MTBE oxidation. TBA production was accounted 54.7% and 58.6% for MTBE oxidation by ENV425 and mixed culture, respectively. The observed maximal transformation yield (T$_{y}$) were 44.7 and 34.0 (nmol MTRE degraded/$\mu$mol n-butane Utilized) by ENV425 and mixed culture, respectively.y.

In this thesis presents line balancing problems of two-sided and mixed model assembly line widely used in practical fields using genetic algorithm for reducing throughput time, cost of tools and fixtures and improving flexibility of assembly lines. Two-sided and mixed model assembly line is a special type of production line where variety of product similar in product characteristics are assembled in both sides. This thesis proposes the genetic algorithm adequate to each step in tow-sided and mixed model assembly line with suitable presentation, individual, evaluation function, selection and genetic parameter. To confirm proposed genetic algorithm, we apply to increase the number of tasks in case study. And for evaluation the performance of proposed genetic algorithm, we compare to existing algorithm of one-sided and mixed model assembly line. The results show that the algorithm is outstanding in the problems with a larger number of stations or larger number of tasks.
