An advanced mobile technology is described for saturating water with oxygen. The MTR(Mass Transfer Reactor) is 2~10 times more effective in dissolving oxygen in water compared to most other systems used in aquaculture, because it can generate extremely small(0.005~0.05mm) bubbles. New fish farming facilities could make use of this technology to build deeper ponds for raising multiple species with optimized conditions for DO(dissolved oxygen), food, light, etc. The proposed technology offers higher DO levels with minimal operating costs. It is easy to use and maintain, with a high reproducibility. Accordingly, the MTR can be industrially applied in the treatment of fish waste and reduction of water consumption during fish farming.

본 논문은 그간 문화시설 건립의 타당성조사에서 쟁점이 되고 있는 수요 추정과 편익 추정에서의 문제점과 개선방안을 제시한다. 여가시간 확대와 소득 증대에 의해 문화시설 공급에 대한 당위성도 있지만 건립 이후의 운영 부실에 따른 경제적 부담 또한 크다. 문화시설의 건립 및 운영의 전문화와 활성화까지를 건립 계획 단계에서 고려하기 위해서 타당성조사라는 관리도구를 활용하고 있다. 본 연구는 국립현대미술관 서울관 건립 타당성재조사 사례를 통해 문화시설 건립 타당성조사 중 경제성 분석의 수요 추정과 편익 추정에서의 쟁점과 개선방안을 제시한다. 문화시설 수요 추정은 유사 시설을 선정하고 중력모델을 사용하고 있으며 향후에는 수요 추정의 정확도를 높이기 위해 준거시설 설정 기준 마련이 필요하다. 또한 타당성조사를 통해 건립된 문화시설인 경우 운영 데이터 및 정보를 공개하도록 유도 및 강제하고 이를 향후의 문화시설 타당성조사에서 수요 추정시 준거시설로 활용할 수 있도록 DB를 구축하는 것이 필요하다. 정확한 편익 추정을 위해서는 복수의 CVM 설문이 요구된다. 현재의 CVM 설문에 병행해서 온라인 비대면 설문을 보조적으로 할 수 있는 방안을 고려할 수 있다. 또한 현재 CVM 설문에서 설문 응답자에 대한 대체재 상기가 부족하여 WTP가 과대할 수 있기 때문에 건립 예정인 문화 시설의 대체재 설명에 대해 영상매체를 이용할 것을 제안한다.

Objectives: In Korea, the top 10% of Medical Aid recipients represent nearly 60% of total payment, with the costs for those disabled for over 365 days representing approximately 30% of total payment. The purpose of this study was to compare Medical Aid use of the disabled with non-disabled recipients, and to identify contributing factors to the total payment in the top 2% of recipients identified as Medical Aid overusers. Methods: Subjects (n=2,211) selected were ${\geq}18$-years-of-age and received >1000 days of co-payment-free type I Medical Aid. Case managers (n=200) conducted interviews in December 2006, and collected data from Health Insurance Review & Assessment Service. Amounts over the 9 months from January September 2006 were analyzed descriptively and using Chi-square, ANCOVA, and robust multiple linear regression. Results: Disabled individuals (mean age 61.3 years) composed 36.6% of subjects; 44.8% of the disabled were male. On a monthly basis per capita, the disabled group averaged 10.5 outpatient days, total payment of 523,000 Korean Won(￦), inpatient payment of ￦359,000, and outpatient payment of ￦183,000. All values exceeded the monthly average for non-disabled individuals. Contributing factors were identified as male gender (￦82,000), elementary school or lower educational level (￦64,000), residence in a small city (￦82,000), lack of family support (￦61,000), kidney disability (￦673,000), intellectual disability (￦151,000), and multiple disabilities (￦119,000). Conclusions: The identification of contributing factors to Medical Aid use by those defined as disabled supports the adoption of comprehensive alternative policies such as strengthening of education and consultation services, provision of alternative facilities, and promotion of self-care.

Purpose: This study was done to investigate the types of breastfeeding visits by mothers twenty-four months after birth and to identify the factors that increased breast feeding rates. Methods: The subjects of this study totaled seven hundred and seventy-four mothers with infants aged 2 years or less who had visited national medical institutions including Sanhujori service facilities, breastfeeding care service facilities, and community health centers. Data was collected from June 22 to July 31, 2009. Data was analyzed using descriptive statistics, $x^2$ test, ANOVA with a post hoc Scheffe test, and multiple logistic regression. Results: Major findings of this study were significant differences of planned length of breastfeeding and breastfeeding self-efficacy in relation to the differing types of breast feeding community visits by mothers. In multivariate logistic regression, baby's age, exclusive breastfeeding at hospital, utilization of breastfeeding care service facility, planned length of breastfeeding, and breastfeeding self-efficacy were independent predictors of the feeding type. Conclusion: In order to increase breastfeeding rates, programs provided by public health care services and medical facilities should start education on breast feeding in the hospital before mothers are discharged and then continue through the use of Sanhujori service facilities and workplace at 3 month and 6 month postpartum.

Fuel cells are known as eco - friendly energy facilities that can use heat energy and electric energy at the same time. Fuel cells are classified according to the temperature and material used, and solid oxide fuel cell (SOFC) is relatively high temperature ($700-800^{\circ}C$). SOFC requires a hot box consisting of a high temperature stack, a reformer, a burner, and the heat exchangers in order to use energy efficiently. The hot box needs to maintain heat insulation performance at high temperature to reduce heat loss. However, Fibrous insulation, which is widely used, needs to be improved because it has a disadvantage that the thermal conductivity is rapidly increased due to the increase of temperature. Therefore, this study was carried out to develop a thermal insulation, which is applied to multiple layers insulation (MLI) technic, that can be used under SOFC operating conditions and prevent a drastic drop in thermal conductivity at high temperature. The developed insulation is consist of a thermally conductive material, a spacer, and a reflective plate. The thermal conductivity of the insulation was measured by in the thermal conductivity measuring device at high temperature range. As a result, it was confirmed that the developed layers insulation have an good thermal conductivity (0.116 W/mK) than fibrous insulation (0.24 W/mK) as a radiation shielding effect at a high temperature of 1,173 K.
