The aim of this study was to assess the nutrient intakes of the elderly subjects in Korea. Dietary assessment was carried out using a semi-quantitative food frequency questionnaire (SQFFQ) developed by our laboratory, which included 98 commonly consumed food items selected from 1998 National Health and Nutritional Survey for Korean population. Subjects (n = 2,660) aged 50yr and over were recruited in Seoul, 6 metropolitan cities, and 8 mid-size cities. Calcium and riboflavin intakes of the elderly subjects aged 65 yr and over (n = 1,974) were much lower compared with Korean RDA. Nutrient intakes of the three age group (50 - 64 yr, 65 - 74 yr, 75 yr and over) were decreased as age increased in male and female elderly. Nutrient intakes of male elderly, 75 yr and over, were significantly decreased while in female elderly nutrient intakes were gradually decreased as age increased. Over 30% of the elderly subjects did not meet 75% RDA for calcium, iron, vitamin A, and riboflavin. The proportion of the elderly subjects whose intakes were below 75% RDA was much higher than the elderly whose intakes were above 125% RDA, especially among the elderly aged 75 yr and over. This study revealed that the Korean elderly had inadequate intakes for many nutrients. This will cause a serious nutritional problem for the elderly.

본 연구는 만경강 유역의 수질 보전을 위한 기초자료를 얻기 위하여 만경강 본류와 이에 유입되는 지천을 선정하여 2001년 5월부터 11월까지 매월 수질 모니터링을 실시하였다. 만경강 유역내 본류 및 지천의 유기물과 영양염류 함량을 조사한 결과, 본류의 T-N은 3.78~12.68 ㎎/L였으며, 지천중 축산폐수가 유입되는 익산천의 농도가 가장 높았다. 본류의 T-P의 BOD는 각각 0.043~0.864 ㎎/L와 2.59~13.29 ㎎/L였으며, 지천중 익산천이 가장 높았다. 본류의 COD는 12.9~119.5 mg/L였으며, 지천중 도시생활하수가 유입되는 추천이 가장 높았다. 만경강 유역 수질저하의 주 원인은 축산폐수였으며, 도시생활하수가 그 다음으로 중요한 원인으로 평가되었다. 만경강 본류의 T-N과 T-P는 하천의 유량이 증가하는 홍수기인 7~8월보다 장마선 갈수기인 5~6월에 높았고, COD는 장마전 갈수기보다 홍수기에 높았으며 장마가 완전히 끝난 영농후 갈수기인 9~11월에도 수질저하가 지속되었다. 만경강에 유입되는 지천중 전반적으로 수질오염이 심각한 익산천과 추천은 영농후 갈수기에 수질이 가장 저하되었고 상대적으로 홍수기에는 양호하였다. A survey on four tributaries along with Mankyeong River was carried out to get the information for the water quality improvement and control. Typical paddy farming were major agricultural practices in Kosancheon and Soyangcheon. Iksancheon was livestock raising watershed. Chucheon was urban watershed. Water quality in six sites of main stream and four sites of tributaries in Mankyeong River were investigated from May to August in 2001. The concentration of nutrients in main stream of Mankyeong River were in the range of 3.78~12.68 mg/L for total nitrogen, 0.043~0.864 mg/L for total phosphorus, 2.59~13.29 mg/L for BOD and 12.9~119.5 mg/L for COD, respectively. Water quality of Mankyeong River mostly exceeded the standard water quality criteria of Korea. Major causes of water pollution were evaluated as sewage of swine and urban area. Among the four tributaries, water quality in agricultural practices, Kosancheon and Soyangcheon was relatively less polluted. While, the highest level of water pollution measured in Iksancheon was due to livestock The water quality of Iksancheon and Chucheon was generally more polluted in the dry period than in rainy period.

콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.
