본 연구에서는 기능성 쌀을 이용한 쿠키를 개발하여 이화학적 관능적 품질 특성을 조사하였다. 반죽의 pH는 기능성 쌀가루를 10% 대체한 반죽이 대조군 보다 유의적으로 높은 pH를 나타내었다. 쿠키의 퍼짐성에서는 20%와 30% 대체한 시료군이 대조군 보다 유의적으로 높은 퍼짐성을 보였다. 시료군의 L값은 대조군이 69.31으로 가장 높았으며, b값은 20%대조 시료군이 35.60의 값으로 가장 높았다. 기능성 쌀가루를 다양한 수준으로 대체한 쿠키의 관능검사를 실시한 결과 기능성 쌀가루를 10% 대체한 시료군이 고소한 냄새, 고소한 맛, 경도, 색의 갈색정도에서 유의적으로 특성이 강하게 평가되었다. 쿠키의 기호도 검사 결과 쿠키의 전반적인 기호도에서 기능성 쌀가루를 20%와 30% 대체한 시료가 대조군과 함께 유의적으로 높은 기호도를 나타내었다. 따라서 기능성 쌀가루로 대체된 쿠키는 모든 대체비에서 대조구와 비교하였을 때 유의적인 차이가 없거나 유의적으로 높은 기호도를 나타내어 기능성 쌀쿠키 개발의 가능성을 보여주었다.

Survey on the food intake status and health condition of the elerly over 65 years old living in Damyang Jeonnam was performed and meal menus for the pavillion were developed using local products. Allowance of the elderly less than 100,000 won was 45%. The local products of the area recognized by the elderly were bamboo shoot (30%) > bamboo (22.5%) > bamboo basket (12.5%) > do not know (15%) > green tea (10%) > rice(7.5%) > vegetable. In dental health, 52.5% of them had bad condition but 62.5% did not use denture at all. The most favorate foods were Korean (92.5%) and Chinese and Japanese were favored by 5%, and 2.5%, respectively. In percentage of eat-out and use of instant foods, 42.5% of them answered that eating-out chances were very rare and 62.5% answered that they do not use instant foods at all. Potassium intakes for the male and female elderly were significantly very low with values of 2579.2 mg and 2601 mg, respectively (p < 0.05). Calorie intakes for men were 1678.5 kcal, which was only 84% of RI and 1470.8 kcal for women (92%). Shortages of nutrition including calcium intake and others were very serious and the meal was not nutritionally balanced based upon the study of GMDFO. The menu for the elderly in busy farming season of the area were developed with the use of local products and the information from the study.

This study analyzed the spatio-temporal change detection of land-use and urbanization in Yongin and Anseong regions, Kyunggi Province, using three Landsat-5 TM images for 1990, 1996, and 2000. Remote sensing (RS) and geographic information system (GIS) techniques were used for image classification and result analysis. Six land-use types were classified using supervised maximum likelihood classification. In the two study areas, the land-use changed significantly, especially the decrease of arable land and forest and increase of built-up area. Spatially, the urban expansion of Yongin region showed a spreading trend mainly along the national road and expressways. But in Anseong region the expansion showed 'urban sprawl phenomenon' with irregular shape like starfish. Temporally, the urban expansion showed disparity - the growth rates of urbanized area rose from the period 1990-1996 to 1996-2000 in both study areas. The increased built-up areas were converted mainly from paddy, dry vegetation, and forest.

We investigated the antioxidant, physicochemical, and sensory characteristics of dried type sodium-reduced Bibimbap using dandelion complex powder (DCP). DCP is known to add moisture to the skin and relieve symptoms of atopic dermatitis. The sodium content of the standard sample was 1,110.87 mg per serving. The sodium was significantly reduced by 30%, resulting in 762.62 mg of sodium for the reduced sodium group (p<0.05). The ash contents of the standard sample group with DCP showed the highest value (3.17%) in all samples and was affected by minerals of DCP (p<0.05). The total flavonoid contents and ABTS radical scavenging activity, indicators of antioxidant, anticancer and antibacterial activities, showed significantly high activities with addition of DCP (p<0.05). In the sensory results, bulgogi and savory flavor of the samples with DCP showed significantly higher values, and samples with DCP received the highest scores for after-taste. All samples were confirmed to be microbiologically safe according to the food code applied to food manufacturers. Pathogenic microorganisms tests were either negative or not detected in all samples.

This study was performed to evaluate the effect of iron supplementation on iron-deficiency-related indices, oxidative stress and antioxidative enzyme activity in female marathoners. Fourteen teenage female marathoners participated in the study. Subjects were divided into two groups: mild anemic and control, depending on their hemoglobin (Hb) level. The mild anemic group had significantly lower RBC count and hematocrit (Hct) and Hb levels compared to the control group. The mild anemic group (〈12.5g Hb/dI, n=7) was given iron supplements (60mg Fe/day) for four weeks during the summer training period. RBC count, Hct and Hb levels showed an increasing tendency through iron supplementation, and significant differences in these variables between the anemic and control groups disappeared in the post-period. There was no difference in plasma malondialdehyde (MDA) between the anemic and control groups. However, catalase (CAT) and glutathione peroxidase (GPx) activity were significantly higher in the anemic group. The significant difference in enzyme activity between the groups disappeared in the post-period. In addition, superoxide dismutase activity significantly decreased after iron supplementation. In conclusion, antioxidative enzyme activity was up-regulated in an anemic condition and mild iron supplementation decreased the antioxidant enzyme activity of female marathoners while improving their anemic condition.

The purpose of this study is to examine the changes in bone mineral density in long-stay patients of a geriatric hospital in relation to physical therapy, thereby providing basic data for preventing the onset or deterioration of osteoporosis in inpatients of geriatric hospitals or relevant facilities. The subjects of this study were 133 elderly patients who had been in H geriatric hospital in Yongin-si for more than four years. Their bone mineral density T-scores at admission and those after four years were measured to compare and analyze the changes in bone mineral density in relation to physical therapy. According to the results, the decrease in T-score for the group without physical therapy was greater by .40 than that for the group with physical therapy, indicating a statistically significant difference between the two groups(p<.01). Accordingly, physical therapy proved to be effective in preventing bone mineral density loss and maintaining the current density.

This study was conducted to investigate the effect of different kinds of traditional Korean soybeans on blood and liver lipids and lipid peroxidation. SD male rats (n=48) were assigned to six different groups and provided experimental diets for 28 days. The protein source of the diet was casein, isolated soy protein (ISP), or casein plus traditional soy powders (yellow bean, huktae, jinuni or seorietae). The ISP, jinuni and seorietae diet decreased blood triglyceride compared to casein group. The ISP groups had lower hepatic total lipid and triglycerides than casein groups. The yellow bean and seorietae group had hepatic lipid lowering effects, but the effect was not found in huktae and jinuni group. The glutamate-oxaloacetate transaminase activity was significantly decreased in ISP and jinuni groups than in casein group. The glutamate-pyruvate transaminase activity was also decreased in ISP group. The results of this study suggest that jinuni, yellow bean and seorietae groups are more effective in lowering body lipids than huktae group.

Freshly squeezed juices were prepared using the domestic Chunggyun, Hanrabong, and imported oranges and physicochemical and sensory characteristics of the juices were investigated. The Chunggyun had significantly the lowest pH value of 3.35, and imported and Hanrabong showed the pH values of 3.82 and 3.93, respectively(p<0.05). The refractive index of Hanrabong showed significantly the highest values of $14.7^{\circ}Bx$ (p<0.05), and the samples of imported and Chunggyun did not show significant differences with indices of 12.5 and 12.2, respectively. The quantitative descriptive analysis(QDA) showed imported sample had significantly the highest values of sweet and sour aroma with values of 11.57 and 11.08, respectively. However, Hanrabong showed significantly the highest value of sweet flavor with value of 12.31. Consumer acceptance test represented the Chunggyun was the most accepted one but did not show any great differences in overall, appearances, and flavor among the samples.

사람 눈의 각막에 평행하게 입사하는 광선의 높이에 따른 결상점을 근사 없이 스넬의 법칙으로 분석하였다. 광선들이 망막의 동일한 한 점에 결상하도록 각막에 입사하는 광선들의 높이에 따른 입사각을 계산하기 위하여 결상점으로부터 광선을 역추적하여 각막 전면에 입사하는 광선의 입사각을 계산 하였다. 눈 자체로는 구면수차를 유발할 수밖에 없기 때문에, 구면 수차를 보정할 수 있는 비구면 렌즈 설계에 대한 조건을 유도 하였다. 계산을 쉽게 하기 위하여 렌즈 후면은 구면으로 고정하고 렌즈 전면을 비구면 렌즈 설계를 위하여 높이에 따른 곡률을 계산하였다.
