This study used latent profile analysis to identify heterogeneous subgroups with respect to the perception of work environment among workers in residential facilities for people with disabilities. The final model yielded five latent profiles of the perception of work environment: 'low workload group' who scored low in time pressure and job responsibility, 'discrimination perception group' who scored low in supervisor support and high in sex and academic/regional discriminations, 'positive perception group' who scored high in work autonomy and peer and supervisor supports, 'high workload group' who scored high in workload, time pressure, and job responsibility, and 'average group' who scored average in most areas. In the case of job satisfaction, positive perception group was the highest, followed by average group, low and high workload groups, and discrimination perception group.

Recently, the opening of the world economy and regional ization of national demand endless endeavors and investments to upbring design-industry for regional economic development. Our domestic commodities, declined in price competitiveness against China and Southeast Asian nations, need construction of brand image of commodities and consumers' response through expanded concernments in marketing spheres. The design-industry is a important means to strengthen competitiveness of the domestic industry through discrimination of commodities and creativity of high added value. Design-industry has some problems in circumstances; commodity development and marketing are below the level in the sphere of manufacture industry yet and businessmen are unwilling to invest demanded for development of new design. Establishment of the personal foundation, useful for accumulating competent designers' experiences and technologies, can not pass limit. In addition, a system and a policy to protect design-industry have a problem in effectiveness. Concrete strategies to activate design industry which meets social and cultural circumstances of Daegu and Gyeongbuk region are to establish policy for construction of specialists' infra, systematization of study & development of design, common ownership of information on design, and expansion of design company. The business to upbring design in the region should be operated to develop competitive commodities which is helpful to the regional economy and to increase value of the regional enterprises' brand. In addition, foundation of design should be expanded personal, material, and informational infra through design-centered so that they are helpful to activate economy of Daegu and Gyeongbuk through making design reformational cluster.

The facilities with new technologies in the recent power plants become larger and need a lot of high cost for maintenance due to stop operations and accidents from the operating machines. Therefore, it claims new systems to monitor the operating status and predict the faults of the machines. This research classifies the normal/abnormal status of the machines into 5 levels which are normal-level/abnormal-level/care-level/dangerous-level/fault and develops the new system that predicts faults without stop operation in power plants. We propose the regional segmentation technique in the frequency domain from the data of the operating machines and generate the Peak-codes similar to the Bar-codes, The high efficient and economic operations of the power plants will be achieved by carrying out the pre-maintenance at the care level of 5 levels in the plants. In order to be utilized easily at power plants, we developed the algorithm appling to a notebook computer from signal acquisition to the discrimination.

This study aims to understand the change of migrant policies, namely assimilation, multiculturalism and social integration, in the West through critical perspectives and to derive implications for the Korea's migrant policy from the experience of the West. In 1970s, assimilation policy was severely criticized from the limitation of cultural diversity, and multiculturalism expanded rapidly in the West focusing on the migrant's right and cultural difference. However, multiculturalism received severely criticism because it makes social isolation and segregation between mainstream society and migrants. Since 2000 social integration became the major policy for migrant incorporation, focusing migrant's attitude and practice to receive the value and culture of mainstream society with the active participation of socioeconomic activities. However, social integration policy reveal some problems which regard migrants as the object of control, and also as the object of discrimination. The experience of the Western policies suggests on the careful selection for the migrant's incorporation policies in Korea with the consideration of social inclusion of migrant, analysis on the problems of multiculturalism and social integration policy, and the necessity of mainstream society's change into the acculturation.

This study contemplated domestic and other country's effluent limitation standards and suggested a methodology to establish technology-base limitation value. Current effluent limitation regulates industrial point sources discriminated by discharge flow rate and by regional distinction in Korea. Discharged $BOD_5$ load from large-scale plants(flow rate above $2,000\;m^3/day)$ exceeds 50% of overall industrial wastewater, which present rationale for discrimination based on plant size. However, regional distinction and pollutant- specific regulation might be insufficient to meet practical effectiveness of wastewater management policy, due to the nearly same limitation. Water quality data and treatment methods were investigated in hospital industry. And their distribution of effluent $BOD_5$ concentrations was statistically analyzed to suggest limitation value. Effluent $BOD_5$ concentrations showed lognormal distribution and $95^{th}$ percentile was corresponded to 87.9 mg/L, which could be suggested as tentative effluent limitation in hospital industry. The $95^{th}$ percentile of log-transformed distribution showed similar value of 86.5 mg/L. This study demonstrated reasonable methodology for establishing effluent limitation reflecting wastewater characteristic and treatment technology in separately categorized industry.

In Korea, the number of foreigners reached about 1,260,000. So we are now living in a multicultural society. There are more than 36,000 multicultural students in kindergarten, elementary, middle, and high school(2010's standards). In other words, Still more multicultural students are expected to increase in the future. As a matter of fact, one of the biggest problems which mixed couples and immigrants from other countries have had is most concerned about possible bias and discrimination of their children. Study has shown that multicultural students are alienated from the others at school, because of their skin colours, the pronunciation they speak Korean, and maladjustment in their school life. Actually, multi-cultural education program should be applied to the first grade in elementary school. Besides, teachers have to direct multicultural and general students with integrated education. Study also found that it is necessary to use more visuals and pictures as the main multi-cultural education. And books and CDs should be used as guide materials. It's desirable that the appropriate time to teach relate to lesson.

As the number of foreigners who stay for a long time increases, their residential concentrations have emerged and developed. This research aims at investigating how and why immigrants' residential concentration sustains and develops. In order to understand the roles of the residential concentration for the immigrants' everyday, we used the framework of grunddaseins funktionen including residence, labor, shopping, education, leisure, commuting, and community activity. Accompanied is a case study of Daelim-dong which is the largest Chinese concentrations. The result shows that combined with co-ethnic preference in residence, various amenities at the concentrations attract new immigrants and hold existing immigrants, allowing the concentrations sustain and develop. It has been pointed out that there are the difference factors that foreign immigrants concentrate residentially: 'co-ethnic residential preference' for immigrants from more developed countries and 'discrimination' for immigrants from less developed countries. However this study shows that the residential concentrations for less-developed-country-immigrants could maintain and develop with grunddaseins funktionen based on co-ethnicity.

This paper attempts to compare and analyze the intensity, trend, and regional gap of income inequality, capitalizing upon the Age-Period-Cohort model which considers age, time and cohort effects, with the 1998-2018 Korea Labor Panel (KLIPS) survey data for respondents living in the Capital and Non-Capital Regions. The main analysis results are as follows. First, in the case of both cohort and age effects, those in their 50~60s, including the so-called baby boomers and '386 generation' living in the Capital Region, have relatively lower income inequality effect compared to that of other age groups and cohorts in the Non-Capital Region. Second, the micro-individual characteristics cannot be ignored to account for a regional gap in income inequality, but rather the effects of structural and institutional omitted variables and the social discrimination effects of individual characteristics variables are more significant in explaining it. Overall, intra-and inter-cohort income inequalities appear to overlap.

Harmful shell-boring species of the genus Polydora (Polychaeta: Spionidae) were frequently reported from commercially important mollusk species in Korea, Japan and China. The traditional approach based on the morphological characteristics showed limitations for species discrimination among shell-boring species. Therefore, DNA barcoding was adopted to identify Polydora species using molecular markers. Two Polydora species (P. haswelli and P. hoplura) in abalone shells were reported from our previous molecular phylogenetic study. In this study, we additionally reported the presence of shell-boring Polydora haswelli in commercially sold shellfish. The taxon-specific cox1 marker used in this study successfully allowed the isolation of P. haswelli from cockle Scapharca subcrenata, mussel Mytilus galloprovincialis, oyster Crassostrea gigas and scallop Argopecten irradians. Polydora hoplura was not found in these shellfish species. The genetic variations were found on the intraspecific level of P. haswelli and the same genotype was also detected in different shellfish species. This result can provide information on a new host and accurate parasitic Polydora species. Moreover, this report can be used as the biodiversity data of Polydora species on the invasion and transition of harmful Polydora species in mollusk aquaculture farms.

This study reflects the regional context of Northeast Asian countries embodied in US-North Korean nuclear tension. The researcher uses the methodological inquiry of practical theology to analyze the political affairs and intertwine with religious education. The ecology of religious education to dismantle the threat of ethnic and racial discrimination such as white supremacy supports a shared pedagogy between students and their teachers in the narrative of Jesus to challenge all forms of oppression as the democratic presence of God.
