사일리지의 사양가치에 가장 크게 영향을 미치는 요인은 사초의 종류에 기인되는 화학조성분이며 사일리지를 적기에 제조하므로 단위면적당 최고의 양분수량을 거둘 수 있다. 유기산의 생성량이 많고 낙산이나 암모니아태질소의 함량이 많으면 사일리지의 품질이 떨어지고 섭취량이 감소되므로 사일리지 품질 증진을 위한 연구방향은 발효를 감소시키고 단백질의 분해를 막는 것이다. 사일리지의 발효에 영향을 미치는 중요한 요인으로는 사초의 화학조성분인 수분, 수용성탄수화물 등과 제조기술에 크게 좌우되는 공기(산소)혼입량이다. 재료의 수분함량은 사일리지 발효품질에 큰 영향을 미치며 수분이 많은 재료는 적당히 예건되면 젖산발효는 덜 제한되는 반면 불필요한 발효가 줄어들고 낙산발효를 억제할 수 있어 품질이 향상되고 기호성이 증진된다. 또한 사초를 알맞은 길이로 절단하므로 답압이 잘되어 공기 배출이 양호해 혐기상태의 유지가 가능하게 되고 사일리지의 취급또한 편리해 진다. 사일리지 첨가제는 재료를 적절히 예건하지 못할 때 필요하고 또한 특별한 조건하에서는 권장되고 있다. 이와같이 사일리지 발효에 도움을 준다는 가능성에도 불구하고 첨가제의 잇점은 양질 사일리지 제조를 위한 제반 처리를 대신할 수 없다. 양건 건초제조에 소요되는 기간은 기후에 크게 영향을 받게 된다. 건초제조 과정 중 포장에서 생기는 건물손실은 외기에 오랫동안 노출되면 잎이나 연한 줄기 부분이 부서지고 카로틴이 파괴된다. 또한 말리는 과정에 비를 맞힐 경우 양분이 용해되어 소화되기 쉬운 영양소와 건물 손실이 증가되며 섬유소함량이 증가되어 소화율과 섭취량이 감소된다. 그러므로 일기 예보에 따라 좋은 날씨가 $3\sim4$일 계속되는 시기를 택하여 적기 수확하고, 줄기의 압쇄(condition), 건조시 풀의 두께를 얇게, 뒤집기, 적절한 수분함량일 때 거둬들이는 조치가 필요하다.

Objectives: This study was conducted to create a 3D printable snack dish model for the elderly with low food or fluid intake along with barriers towards eating. Methods: The decision was made by the hybrid-brainstorming method for creating the 3D model. Experts were assigned based on their professional areas such as clinical nutrition, food hygiene and chemical safety for the creation process. After serial feedback processes, the grape shape was suggested as the final model. After various concept sketching and making clay models, 3D-printing technology was applied to produce a prototype. Results: 3D design modeling process was conducted by SolidWorks program. After considering Dietary reference intakes for Koreans (KDRIs) and other survey data, appropriate supplementary water serving volume was decided as 285 mL which meets 30% of Adequate intake. To consider printing output conditions, this model has six grapes in one bunch with a safety lid. The FDM printer and PLA filaments were used for food hygiene and safety. To stimulate cognitive functions and interests of eating, numbers one to six was engraved on the lid of the final 3D model. Conclusions: The newly-developed 3D model was designed to increase intakes of nutrients and water in the elderly with dementia during snack time. Since dementia patients often forget to eat, engraving numbers on the grapes was conducted to stimulate cognitive function related to the swallowing and chewing process. We suggest that investigations on the types of foods or fluids are needed in the developed 3D model snack dish for future studies.

In this study, the skin-improving effect was investigated through the oral intake of DuOligo (51.67% lactulose and 15.8% galactooligosaccharides). Thirty seven healthy women (40~60 in ages) were divided into placebo group (dextrin) and treatment group (DuOligo group), and each group was given a sample for oral intake for 8 weeks. After that, corneometer value, transepidermal water loss (TEWL), melanin index, erythema index, and wrinkle index were measured. As a result, moisture content of DuOligo group increased 38.22% than control group after 8 weeks significantly (p < 0.01). The TEWL of control group decreased by $3.39g/h/m^2$ after 8 weeks but the TEWL of DuOligo group decreased by $5.32g/h/m^2$ after 8 weeks. The melanin index of the control group was significantly increased with times, but the melanin index of the DuOligo group did not show any significant difference with times. The total wrinkles, length of total wrinkles, number of wrinkles, and depth of wrinkles significantly decreased (p < 0.05) compared to the control group. These results suggested that the applicability of DuOligo as a skin improving functional material was confirmed.

Purpose: This study was done to examine the differences in the fluid volume deficit according to levels of depression and BMI. The results of this study will provide fundamental information for developing nursing interventions for hydration management. Method: The participants were 51 hospitalized elderly people in K province. Data were collected from September 4 to 30, in 2006. A structured questionnaire was used for the data collection. Frequencies, Percentages, Means, Standard Deviation, t-test, Mann-Whitney U test, and Kruskal-Wallis test were used with the SPSS Program to analyze the data. Results: There were significant differences in the fluid volume deficit between elders in the depressed and normal groups. Participants who had a BMI of less than $21kg/m^2$ had the highest fluid volume deficit. Conclusion: Water is an essential part of the human body although it is least studied in elderly people. Health care providers need to increase awareness of the importance of hydration status among hospitalized elderly people with chronic illnesses.

Since measuring the size of kidney with sonography becomes an important index for diagnosis, treatment, and prognostic prediction in kidney disease, the accurate measurement and evaluation on this are clinically very important. Accordingly, the purpose of this study was to increase reproducibility and objectivity in measuring the size of kidney by enumerating factors that have an impact for measurement. It targeted 44 adults in Korea at the age of 21-27. It measured in order for both kidneys to be seen most largely while changing a subject-examiner's position in a state of fasting for 8 hours and a transducer's approaching direction. It compared a size of kidney by measuring, respectively, with the same method in 30 minutes and in 1 hour after drinking water in 700-1,000cc. In case of the lateral approach scan in decubitus position, the average length of the kidney both to the right and the left and the deviation of measurement to be the largest. In NPO(None Per Oral) state, the average length in the right kidney was 10.19cm, and the average length in the left kidney was 10.33cm. In 60 minutes after taking moisture, the average length in the right kidney was 10.94cm, and the average length in the left kidney was 11.13cm. In comparing the average length of the kidney in NPO state and its average length in 60 minutes after taking moisture, the size swelled by 7.3% for the length in the right kidney and by 7.7% in the left, thereby having been indicated to be statistically significant(P<0.003). The measurement in a size of kidney by using ultrasound may be measured differently depending on a patient's state of taking moisture and a transducer's approaching direction. It is thought that when the measurement in a size of kidney is especially important clinically, the intake and intake time in moisture need to be considered and that measuring with the posterior approach in prone position is a good method aiming to increase reproducibility in measuring length of the kidney.

Purpose: This study was conducted to examine coffee consumption behaviors, dietary habits, and nutrient intakes by coffee intake amount among university students. Methods: Questionnaires were distributed to 300 university students randomly selected in Gongju. Dietary survey was administered during two weekdays by the food record method. Results: Subjects were divided into three groups: NCG (non-coffee group), LCG (low coffee group, 1~2 cups/d), and HCG (high coffee group, 3 cups/d) by coffee intake amount and subjects' distribution. Coffee intake frequency was significantly greater in the HCG compared to the LCG (p < 0.001). The HCG was more likely to intake dripped coffee with or without milk and/or sugar than the LCG (p < 0.05). More than 80% of coffee drinkers chose their favorite coffee or accompanying snacks regardless of energy content. More than 75% of coffee takers did not eat accompanying snacks instead of meals, and the HCG ate them more frequently than LCG (p < 0.05). Breakfast skipping rate was high while vegetable and fruit intakes were very low in most subjects. Subjects who drank carbonated drinks, sweet beverages, or alcohol were significantly greater in number in the LCG and HCG than in the NCG (p < 0.01). Energy intakes from coffee were $0.88{\pm}5.62kcal/d$ and $7.07{\pm}16.93kcal/d$ for the LCG and HCG. For total subjects, daily mean dietary energy intake was low at less than 72% of estimated energy requirement. Levels of vitamin C and calcium were lower than the estimated average requirements while that of vitamin D was low (24~34% of adequate intake). There was no difference in nutrient intakes by coffee intake amount, except protein, vitamin A, and niacin. Conclusion: Coffee intake amount did not affect dietary nutrient intakes. Dietary habits were poor,and most nutrient intakes were lower than recommend levels. High intakes of coffee seemed to be related with high consumption of sweet beverages and alcohol. Therefore, it is necessary to improve nutritional intakes and encourage proper water intake habits, including coffee intake, for improved nutritional status of subjects.
