  • In this study, the amount of harmful fungi and bacteria contained in the drainage and culture medium from the paprika hydroponic facility is identified. In addition, by proposing the necessity of effective purification of discharged drainage, this study attempted to confirm the possibility of drainage reuse. Finally, this study provides basic data on the basis for calculating the need for purification facilities in the future, as well as improvements in horticulture facility for sustainable agriculture. As a result of the analysis, a total of 12 types of fungi were detected in paprika medium and 10 types of fungi were detected in the drainage, and their densities were 130 and 68, respectively. Among the fungi detected in the media and drainage of the paprika hydroponic facility, the fungi with the highest detection frequency are Fusarium, Phytophthora, and Pythium. In the case of bacteria, a total of 2 types of bacteria were detected in the paprika facilities, and the density was 28 and 23, respectively. Therefore, in order to reuse the drainage and settle the circulating hydroponic cultivation system, a water treatment process capable of appropriate treatment is required.

  • Culture-dependent and culture-independent denaturing gradient gel electrophoresis (DGGE) analyses were employed to investigate the bacterial community associated with a natural dye wastewater treatment facility. A total of 104 (influent water, 48 strains; aeration tank, 25; settling tank, 31) bacterial strains were isolated. Based on the 16S rRNA gene sequences comparison analysis, the isolates belonged to four phyla: Proteobacteria, Actinobacteria, Firmicutes, and Bacteriodetes. Seventeen DGGE bands representing dominant taxa in each sample were cloned and partially sequenced. The same four phyla were detected by DGGE fingerprinting. The most dominant taxon retrieved by both methods was the member of the phylum Proteobacteria with Alphaproteobacteria as the predominant class. The bacterial community associated with the natural dye wastewater treatment facility is composed of parasites of animals and plants, decomposers of polysaccharides and dyes, and producers of extracellular polysaccharides.

  • This study aims to understand the experiences of rights-based social work practice in a residential facility for people with intellectual disabilities. A representative residential facility practicing a human rights perspective was selected by recommendation of professional groups. Using a qualitative case study method, data was collected and analysed. In detail, it explores the experiences of rights-based social work practice at both organizational and individual levels respectively, and then discusses ethical dilemmas that arise from workers in the process of rights-based social work practice. According to results at the organizational level, rights-based social work practice of the residential facility began from workers' interests in needs of users with intellectual disabilities. Some trials to apply human rights in social work practice resulted in regulations for people with intellectual disabilities and stepped up organizational culture on human rights perspectives. And, at the individual level, self determination and choice of users with intellectual disabilities were stressed among various forms of human rights. As the results of rights-based social work practice, it appeared to be improved for the participation of the users, workers' human rights sensitivity, and qualities of rights-based activities. However, ethical dilemmas still existed. Hence, rights-based social work practice should understand a process of dynamic interaction between users and workers, which require workers to endeavor continuously. This study is significant in that it explored rights-based social work practice, focusing on field experiences for the first time in Korea, and suggested practical tasks to settle it down in the future.

  • Public sports facilities, which have increased in number due to continued government attention and investment, are used by a large number of residents in the province. However, the safety management in some facilities is limited due to being carried out with reference to safety management standard manuals as a mere formality. The purpose of this study was to analyze the current safety management status of public sports facilities in Gangwon and to seek out a policy direction that can be used safely by provincial residents. To this end. the study made a comprehensive review of central government and Gangwon government policy trends in sports facility safety management in Gangwon along with actual cases, from which it made the following suggestions for policy directions. First, it proposed the designation and operation of specialized institutions using locally established development and municipal companeie,. universities and cooperatives. and the training and fostering of safety managers for sports facilities. Secod, it proposed the establishment of a foundation to promote a sport facility safety culture such as designation of and commendation for excellent facility safety management on the provincial level. holding case presentations on safety and responsiveness. sports safety experience plazas, sports safety classes, and cartoons for public relations. Third, it proposed setting the foundation for a safety management system that takes into account the greater quantity of leisure sports facilities compared to other cities and provinces. Fourth, it proposed the establishment of an institutional basis to establish support ordinance for sports facility safety management that meets the local conditions in Gangwon. Fifth, it proposed safety management measures for sports facilities at the central government level in parallel with a basic plan for sports facility safety management tailored to Gangwon that matches the conditions on the ground in the region.

  • Objective: This paper presents additional considerations related to organization and safety culture extracted from recent human error incidents in Korea, such as station blackout(i.e., SBO) in Kori#1. Background: Safety culture has been already highlighted as a major cause of human errors after 1986 Chernobyl accident. After Fukushima accident in Japan, the public acceptance for nuclear energy has taken its toll. Organizational characteristics and culture became elucidated as a major contributor again. Therefore many nuclear countries are re-evaluating their safety culture, and discussing any preparedness and its improvement. On top of that, there was an SBO in 2012 in the Kori#1. Korean public feels frustrated due to the similar human errors causing to a catastrophe like Fukushima accident. Method: This paper reassesses Japan's incidents, and revisits Korea's recent incidents. It focuses on the analysis of the hazards rather than the causes of human errors, the derivation of countermeasures, and their implementation. The preceding incidents and conclusions from Japanese experience are also re-analyzed. The Fukushima accident was an SBO due to the natural disaster such as earthquakes and a successive tsunami. Unlike the Fukushima accident, the Kori#1 incident itself was simple and restored without any loss and radioactive release. However, the fact that the incident was deliberately concealed led to massive distrust. Moreover, the continued violation of rules and organized concealment of the accident are serious signs of a new distorted type of human errors, blatantly revealing the cultural and fundamental weakness of the current organization. Result: We should learn from Japanese experiences who had taken pride in its safety technology and fairly high confidence in safety culture. Japan's first criticality accident in JCO facility splashed cold water on that confidence. It has turned out to be a typical case revealing the problems in the organization and safety culture. Since Japan has failed to gain lessons and countermeasure, the issue persists to the Fukushima incident. Conclusion: Safety culture is not a specific independent element, which makes it difficult to either evaluate it properly or establish countermeasures from the lessons. It may continue to expose similar human errors such as concealment of incident and manipulation of bad data. Application: Not only will this work establish the course of research for organization and safety culture, but this work will also contribute to the revitalization of Korea's nuclear industry from the disappointment after the export contract to UAE.

  • This landscape design proposal was presented to a design competition for the Culture.Welfare.Administration Complex of Yongin-City which was held by Yongin-City in December, 2001. The site is located at 68-19 Yukbuck-dong, Yongin-City, Kyunggi-do and has an area of 236,449$m^2$. The judging criteria for landscape design set by the Yongin-City could be articulated as follows: an environment friendly design respecting the surrounding environment, a locale as a community center of Yongin-City, a resting place for the welfare of employees and visitors, and finally a place with diverse landscape elements reflecting the individual identity of each facility. This proposal chose the main design concept of this project as‘Nature meets City'. A grove of pine trees fragments the multi building complex, so that‘nature'was brought into the‘city'. A double ground system was introduced to respect the existing topography and to enhance the efficency of the land. This design proposal consists of four segments. Each segment has its own design theme. Outdoor space of this multi-purpose complex was designed with themes of nature, culture, welfare and administration. Space composition with grid and natural looking curvilinear lines was a design motive for this complex. The nature oriented planting design was introduced to respect the existing groves of Mt. Suksung. Specific species were chosen to follow its own spatial character in each space. An environmental sculpture called‘Dream Soaring'was placed in the middle of‘Citizen Plaza'. Its light and feather-looking shape symbolizes the vision of Youngin-City. At night people can watch the diverse color changes on its mirror-like surface.

  • This study was attempted to grasp the push-pull factors of urban to rural migrants in relation to services and infrastructure of rural welfare and culture. Online and offline survey were conducted for urban residents who were willing to return to the rural area and those who were already returning to the rural area. In the fields of health care, social welfare, and education, it was found that the satisfaction level of urban-to-rural migrants was relatively higher than those of latent urban-to-rural migrants. In the field of culture, leisure and sports, the level of satisfaction and concern were similar, so it was found that the expectations for the field were relatively high before returning rural area. As for the agreement degree to expand support, the demand for emergency medical facilities and dementia care program was the highest, and the demand for health care was found to be relatively high. The results of the survey on the top priority items indicate that latent urban-to-rural migrants require support of facility and space item and expansion of program item, and urban-to-rural migrants have high demand for expansion of program item in all field except healthcare field. The results of this study are expected to provide useful information for establishing the direction of the rural area development project in connection with the revitalization of policy of people return to rural area.
