Since the permanent shutdown of Kori Unit 1 in 2017, a full-scale decommissioning project for a commercial nuclear reactor has been approaching. It is estimated that about 160,000 t of low-activity concrete waste will be produced from decommissioning of one unit of this commercial nuclear power reactor. Accordingly, it is necessary to review whether the effectiveness of the current regulatory framework for clearance waste (i.e. waste stream that meets activity concentration guidelines or dose criteria for clearance set forth in NSSC Notice No. 2017-65) can be maintained for the clearance of a bulk amount of concrete waste. In this regard, the IAEA SRS No. 44, which was used as a basis for revision of the Korean clearance regulations, is thoroughly analyzed and the radiological effects from four different clearance scenarios, along with input values and parameters derived from industrial practices in Korea, were evaluated. Though it is shown that the maximum annual dose from most recycling scenarios will be less than the clearance dose criterion for the normal scenario (i.e. an order of magnitude of $0.01mSv{\cdot}y^{-1}$), the radiation dose, estimated with conservative assumptions for the banking scenario, may exceed the above clearance dose criteria. Therefore, for safe and sustainable clearance of the bulk amount of concrete waste, it is required to diversify the concrete waste processors, perform more detailed site-specific assessment, and apply limiting conditions to the banking scenario.

After the construction of waterworks automatic meter reading with 15 mm diameter digital water mater with magnetoresistance sensor developed in this study at 96 households of apartment complexes located in Incheon-City B-Gu S-Dong, the feasibility of field application of waterworks automatic meter reading was evaluated. The field application of waterworks automatic meter reading was performed from July to December in 2011, and average reception rate was as low as 84.6% due to the instable wibro networks, the existence of communication blackout and temporary malfunction of router. After the extraction of 10 households with one to five residents out of 96 households by using stratified random sampling method and analysis of domestic water use, it was found that domestic water use was significant at August and showed a decreasing trend at September, followed by increase in domestic water use at November and decrease in domestic water use at December. This phenomenon should be attributed to weather factors (temperature, humidity, etc.), which significantly affected domestic water use. Similar trend in domestic water use in terms of weather factors was obtained in case of Liter per capita day of water use after the extraction of 30 households out of 96 households by using stratified random sampling method. After analysis of Liter per capita day for 96 households, single residents increases resulted in reduction of domestic water usage by about 14% of Liter per capita day. These results might be due to the fact that domestic water usage such as laundry, beverages, catering, cleaning, etc. should be required for even the household with one resident, whereas domestic water usage for those common utilization can be significantly saved for the household with more than one resident.

The current study investigated delinquent school- dropout adolescents and general dropouts' differences in individual, social factors and experiences after school dropout. Data was collected through a nationwide survey(N=209) from dropout adolescents. Findings reveal that gender, age, disabilities, work experience parent cohabitation, and residential area were significant in the individual factor. Dropout time, social agency, school return experience, and GED exam pass were significant in the social factors. Groups showed differences in experiences after dropout, and self evaluation while the general group had needs for vocational education. Dropouts wanted to go back to school. Implications such as focusing on differences of each group and developing various education system and policies are needed. Limitations and implications of the study are discussed.

본 연구의 목적은 한국에서 장래에 이루어질 노인주거연구의 주제를 예측할 수 있도록 일본, 미국, 한국의 노인주거연구의 경향의 차이를 파악하고 비교하기 위한 것이다. 본 연구는 세나라에서 1940년대부터 1990년대 현대까지 발표된 노인주거연구에 대한 학술지와 논문을 분석함으로써 이루어졌다. 세 나라에서 전체 772편의 논문을 수집하여 이를 발표된 연도와 주제에 따라 분류하였다. 본 연구는 일본과 미국의 연구 경향의 특징을 별도로 발표한 후속 연구이다. 일본에서는 1950년대에 노인주거에 대한 연구가 시작되어 80년대 후반에 절정을 이루었으며, 그 이후로 서서히 관심이 줄어들고 있는 추세이다. 일본에서의 주요 주제는 노인홈과 노인시설내의 주 생활조사, 3대 동거 주택, 유료노인홈과 노인시설의 소비자 문제등이다. 미국의 경우, 노인주거의 연구는 일본보다 빠른 1940년대에 시작되어 70년대와 80년대에 걸쳐서 다른 때보다 더 많은 연구가 발표되었다. 주요주제는 1970년대부터 80년대에는 노인주거와 노인시설에 집중되어 있었으나 80년대 이후에 노인주거의 연구방법과 노인주택정책방향으로 관심이 바뀌고 있다. 한국에서의 노인주거에 대한 연구는 세나라 중에서 가장 늦은, 1970년대 후반부터 시작되어 80년대 후반 이래로 그 관심이 점점 증가하고 있다. 한국에서 가장 관심이 있는 연구대상의 하나는 일본과 마찬가지로 기혼자녀와 노부모와의 동거주택에 대한 주제이다. 이상 세나라의 연구주제에서의 차이점은, 한국과 일본에서는 모두 노인주거와 연구방법 분야에는 비교적 관심이 적은 반면, 미국에서는 3대동거주택에 대한 관심이 적은 것이다. 일본과 미국 두나라에 비하여 한국에서는 노인주거 연구에 있어서 아직까지 다양한 주제를 발견하기 어려운데 그 이유는 한국에서는 노인주거에 대한 구체적인 개발이 아직까지 이루어지지 않아서 노인주거에 대한 경험도 많지 않기 때문이라고 생각된다. 앞으로 한국에서도 노인주거가 개발된다면 그 후에는 보다 다양한 연구주제가 나타날 것이라고 기대된다. 예를 들면 노인거주시설의 질적인 비교, 특수한 형태의 노인주거에 대한 요구, 노인주거내의 주생활조사나 평가, 노인을 위한 설비의 디자인 등에 관한 연구들을 생각해 볼 수 있다.

The aim of this study was to investigate the association between perceived periodontal status and sexual function among adult men. Three hundred thirty adult male participated in this study living at Changwon and Jinju. All the participants surveyed the socio-demographic characteristics, perceived periodontal status, stress, and international index of erectile function (IIEF) using self-administrated questionnaire. The univariate and multivariate analyze were adapted to access the crude and adjusted associations using PASW Statistics 18.0. In univariate analysis, there were significant differences between perceived periodontal status and IIEF and most of socio-demographic characteristics (p<0.05), but no significant differences between stress and all of socio-demographic characteristics (p>0.05). The sexual function was negatively correlated with perceived periodontal status (r=-0.228, p<0.001) and stress (r=-0.257, p<0.001), respectively. In multivariate analysis, perceived periodontal status was significantly associated with sexual function (b=-0.889, p=0.030) after adjusting for socio-demographic characteristics and stress. Therefore, it is found that perceived periodontal status negatively influenced on sexual function in adult men.
