The free-living amoeba and Acanthamoeba sp. are widely distributed in fresh water, soil, air and dust in the world. We studied distribution of amoeba from low Nakdong River(Mulgum and Maeri) and removal efficiency in water treatment process of Busan metropolitan city. During this investigation, water quality showed pH $7.4{\sim}9.6({\pm}1.1)$, water temperature $2.0{\sim}29.0({\pm}17)^{\circ}C$, turbidity $4.8{\sim}27.4({\pm}11.0)$ NTU, chlorophyll-a $10.3{\sim}109.0({\pm}44.3)\;mg/m^{3}$, BOD $1.7\sim4.9({\pm}2.6)$ mg/L, COD $3.1\sim-6.9({\pm}5.0)$ mg/L and total coliform $17\sim920({\pm}200.5)$ MPN/100 mL. The free-living amoeba were detected highly than Acanthamoeba sp., 11 out of 22 in raw water samples were positive (50%) for Acanthamoeba sp. from February 2005 to December 2005. The seasonal characteristics of tree-living amoeba and Acanthamoeba sp. in raw water were mainly distributed through the spring to the early fall. When tree-living amoeba and Acanthamoeba sp. were passed through the water treatment of pilot-plant, approximately 80% was sure to be removed through pre-ozonation, sedimentation, send filtration. 100% was removed after post-ozonation process. All of the isolated amoebas from Nakdong River were Acanthamoeba sp. AC311 18S ribosomal RNA gene with 98% nucleotide sequence homology.

'Long-life' which has been the perennial interest to human beings also carries the risk of multiple losses such as the death of the family members and friends, the loss of physical and cognitive functions. In that regards, living a long life to be the 'oldest-old' could mean not only a 'symbol of successful aging' but also a hardship and low quality of life at the same time. Therefore, the issue of the quality of life of the oldest old has been the subject of the much of the public and research concern in recent days. While there has been increased awareness about the importance of the subjective aspects of the quality of life and meanings attached to the extended life, most researches on the quality of life of the oldest-old have focused only on the objective conditions of the quality of life such as health, economic status and housing conditions. To overcome these limitations this study aims to explore the subject meaning of 'living a long life' in Korean society by investigating centenarians and their caregivers' interpretations of aging experiences. Qualitative data were gathered from the forty-nine Korean centenarians and their caregivers through in-depth interview. Each interview was tape-recorded and transcribed verbatim. Researchers read each transcript a number of times to get some emerging themes. Most striking result was the fact that most of the centenarians express the 'guilty feelings' and try to offer the 'excuses' about their long life. This results were quite contrary to the results of the studies, done in Japan and western countries like Sweden, United States and Germany, where most of the oldest-old express quite positive interpretations about their long-life and take pride in their longevity. Lack of social support, cohort characteristics of the Korean oldest-old and the cultural interpretations linking the death of children to the long life of older generation are given as possible factors to these unique findings of Korean study. The policy implications of the results are discussed.

This study attempted to understand the effect of subjective class consciousness on the quality of life of female elderly people and to verify the multi-mediated effect of expectation of living standards and depression. To this end, an analysis was conducted using the SPSS Process Macro for 8,070 female elderly people aged 55 or older in the data of the "2018 Aging Research Panel Survey 7" of the Korea Employment Information Service. As a result of the analysis, first, it was found that the higher the subjective class consciousness of the elderly women, the higher the quality of life. Second, the higher the subjective class consciousness of the elderly women, the higher the expectation of living standards and the lower the depression. Third, in the relationship between the subjective class consciousness and quality of life of female elderly, when expectations and depression of living standards were simultaneously put into the regression equation, both variables were found to have significant mediating effects. Based on these research results, practical and policy implications for improving the quality of life of the elderly women were discussed together.

Quality of life for people living with HIV/AIDS is significant as it concerns the treatment process, survival rate, HIV/AIDS prevention and treatment as well. Prevalent prejudice in our society significantly lowers the quality of patient's life. There is a need for an intervention and the effort to eliminate the stigma in order to lessen the negative effects as well. However, there are very few researches that examine the quality of life when it comes to people living with HIV/AIDS; even less when it comes to research that examines the stigma that affects the quality of life negatively. Therefore, this research seeks to verify the moderating effects of social support that seek to eliminate the stigma upon the quality of life in people living with HIV/AIDS. Research had been conducted with 102 people living with HIV/AIDS and the balancing effect of the social effort was verified through hierarchical regression analysis and a simple slope test. As the result of the research, control variables such as educational level and whether the patient has a job or not have significant effect and the stigma that the patient is aware of has significant negative effect. Social support had positive effect in quality of life and that it has a moderating effect on stigma which in turn affects the quality of life. Based on these results, social work related implications that were suggested are as follows; need for information and education as to better the quality of life for people living with HIV/AIDS and eliminate the social stigma and that group support program based on the local community which is needed for social support. Further research was advised based on the limitations of this research.
