스펀지 케이크 제조시 설탕의 10%에서 40%까지 sorbitol과 maltitol로 대체하여 케이크 반죽의 비중 및 pH와 스펀지 케이크의 제품 특성으로 부피 및 조직감을 측정하였다. 반죽의 1차 비중은 대조구에 비하여 sorbitol과 maltitol을 첨가한 시험구들에서 낮았고, 그 첨가량이 많을수록 낮았다. 2차 비중도 같은 결과로 첨가량이 많을수록 낮아졌고, maltiol보다는 sorbitol에서 더 낮은 결과를 보였다. 반죽의 pH는 대조구에 비하여 sorbitol과 maltitol을 대체하였을 때 높았고, 대체량이 많을수록 높아졌다. 케이크의 부피는 대조구에 비하여 sorbitol과 maltitol을 대체한 시험구에서 크게 나타났다. 대체량이 20%까지는 sorbitol에서 부피가 컸고, 30% 이상에서는 maltitol에서 크게 나타났다. 스펀지 케이크의 조직감으로 경도는 대조구가 가장 높았고, sorbitol과 maltitol을 대체한 시험구에서 낮게 나타났다. Sorbitol과 maltitol의 비교에서는 sorbitol을 첨가한 시험구가 다소 낮은 경도 값을 보였다.

Purpose: The study was aimed at qualitatively enhancing and promoting a home visiting nursing program established in Korea on July 1, 2008, as part of the Long-Term Care Insurance for the Elderly program. Methods: Structural, procedural and consequential aspects of home visiting nursing care wereclassified on the horizontal axis by applying the standard notions for the evaluation of medical care (Donabedian, 1998). At the same time, the home visiting nursing care service support system and the service provision system weredivided on the vertical axis with reference to the accreditation standards for home visiting nursing care organizations suggested by the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO, 2008). The data were collected from June 4, 2008 to October 27, 2008, and were analyzed using SPSS ver. 15.0. Results: Twenty-two (proposed) standards, centered on the standard elements under the conceptual framework of the study, were developed, and comprised structural aspects (n=10), procedural aspects (n=6) and consequential aspects (n=6). Those criteria and indicators underwent two content validity surveys among groups of home visiting nursing care research and training experts. The research produced 22 proposed standards, 50 proposed criteria and 166 proposed indicators. Conclusion: The home visiting nursing care standards developed pursuant to the Long-Term Care Insurance for the Elderly Act and the applicability of these standards need to be verified by home visiting nurses. These proposed standards should prove useful in developing an assessment tool to encourage the qualitative enhancement of visiting nursing care in Korea.

The purpose of this study was to serve as a basis for better student practice in dental hygiene and for determining educational direction for dental hygiene clinical education by examining what students and clinical-practice instructors thought on clinical practice and what factors gave an impact to clinical education. For attaining the purpose, an investigation was made of 449 third-grade students in the department of dental hygiene at seven educational institutes in Seoul and Kyoung-gi province. 246 instructors in charge of the clinical practice of the students at dental hospital or clinics were also examined. The findings of this study were as follows: 1. The instructors and students had different opinions on the number of trainees, training time, beginning of training, and assessment(p<0.05). The instructors thought that a trainee was appropriate for an instructor(59.8%), and that training time was not sufficient(30.8%). They considered it proper for students to start practice during the summer vacation of second year(21.5%), and responded that assessment should be done by the dentist, dental hygienist or professor in charge(44.7%). However, the students had an idea that an instructor should take charge of 2 or 3 trainees(47.4%), and that there was a lot of training time(55.7%). They considered it appropriate to start practice in the first term of second grade(l9A%), and thought the assessment should be made by the dentist and dental hygienist in charge(44.8%). 2. The students' satisfaction was clinical practice was affected(p<0.05) by their own selection of training institutes(28.1%), the absence of trainee from other colleges(29.4%), ample practice time(28.3%), implementation of student assessment once a day(45.3%), diverse practice opportunities (45.5%), and easy traffic to the training institute(32.9%). 3. The achivement of clinical practice was influenced by practice opportunities, the degree of faithful treatment performance, the frequency of student assessment, the number of trainees, traffic to training institutes, assistance in understanding theoretical knowledge of clinical practice, and assessment methods(p<0.05).

Mistletoe lectin has been reported to induce apoptosis in different cancer cell lines in vitro and to show antitumor activity against a variety of tumors in animal models. We previously demonstrated the Korean mistletoe lectin (Viscum album var. coloratum, VCA)-induced apoptosis by down-regulation of Bcl-2 and telomerase activity and by up-regulation of Bax through p53- and p21-independent pathway in hepatoma cells. In the present study, we observed the induction of apoptotic cell death through activation of caspase-3 and the inhibition of telomerase activity through transcriptional down-regulation of hTERT in the VCA-treated A253 cells. We also observed the inhibition of telomerase activity and induction of apoptosis resulted from dephosphorylation of Akt in the survival signaling pathways. In addition, combining VCA with the inhibitors of phosphatidylinositol 3-kinase (PI3-kinase) upstream of Akt, wortmannin and LY294002 showed an additive inhibitory effect of telomerase activity. In contrast, the inhibitor of protein phosphatase 2A (PP2A), okadaic acid inhibited VCA-induced dephosphorylation of Akt and inhibition of telomerase activity. Taken together, VCA induces apoptotic cell death through Akt signaling pathway in correlated with the inhibition of telomerase activity and the activation of caspase-3. From these results, together with our previous studies, we suggest that VCA triggers molecular changes that resulting in the inhibition of cell growth and the induction of apoptotic cell death of cancer cells, which suggest that VCA may be useful as chemotherapeutic agent for cancer cells.

BACKGROUND/OBJECTIVES: The aim of this study was to analyze specific foods influencing absolute nutrient intake and between-person variations of nutrient intake among Korean preschoolers. SUBJECTS/METHODS: This study included 2,766 participants aged 1-5 years in the 2009-2013 Korea National Health and Nutrition Examination Surveys. Dietary data were obtained from a 24-h dietary recall method. Major food sources of absolute nutrient intake were evaluated based on percent contribution of each food. To assess the contribution of specific foods to between-person variations in nutrient intake, stepwise multiple regressions were performed and cumulative $R^2$ was used. RESULTS: White rice and milk were main food sources of energy, protein, carbohydrate, phosphorus, iron, potassium, thiamin, riboflavin, and niacin. The percentage of fat contributed by milk was 21.3% which was the highest, followed by pork, soybean oil, and egg. White rice accounted for 25% and 40% of total variability in total energy and carbohydrate intakes, respectively. About 39% of variation in calcium intake was explained by milk while 40% of variation in phosphorous intake was explained by cheese. The top 10 foods contributing to between-person variations in nutrient intakes were similar with food items that mainly contributed to absolute nutrient intakes. The number of foods explaining 90% of absolute amounts of nutrient intakes varied from 28 for vitamin A to 80 for iron. CONCLUSIONS: This study identified specific foods that contributed to absolute nutrient intakes and between-person variations in nutrient intakes among Korean preschoolers. Our findings can be used to develop dietary assessment tools and establish food-based dietary guidelines for young children.

The purpose of this study is to explore university students' Hanbok rental behavior and to examine factors that influence their intention to rent Hanbok. Questionnaires were distributed in Universities in the Seoul metropolitan area, and the final 202 responses were used for data analysis. For data analysis, descriptive statistics, factor analysis, cluster analysis, t-tests, and multiple regressions analysis were used. Sixty-one percent of those who have experienced Hanbok rental said they rented Hanboks to experience tourism and 22 percent said they rented Hanboks to take pictures, and the main rental places are tourist attractions such as Jeonju Hanok Village. Respondents indicated that the design and color of Hanbok were important product attributes when they consider renting a Hanbok. They also indicated that the opinions of other users posted on the Internet/Social Network were their main source of information for Hanbok rental. The result of cluster analysis showed that there were two groups of Hanbok rental consumers based on clothing consumption values: novelty-seeking group and practicality-seeking group. The two groups were different in terms of few factors of the benefit sought of Hanbok rental, product attributes, and information sources. Regression analysis revealed that traditional culture perception, purpose-built Hanbok pursuit benefit, pragmatic pursuit benefit, attitude toward Hanbok, and the previous Hanbok rental experience significantly affected respondents' intention to rent Hanbok. Based on the results, this study summarizes the key features of each group and provides suggestion for developing strategic marketing activities.

Objectives: This study examined the characteristics and nutritional risk of the elderly who receive home delivery services. We then analyzed the effects of the characteristics of the elderly who receive the home-delivery meal service on their nutritional risk. Methods: A total of 220 respondents who receive home-delivery meal service in Seoul participated in the survey. The survey consisted of the characteristics of the elderly (health status, tooth condition, physical activity, social participation activity, depression and relationship with neighbors), nutritional risk assessment and other general matters. The data was analyzed by using the SPSS program. Cross-tabulation analysis, t-test, correlation analysis and regression analysis were all conducted. Results: 47.0% of the subjects were under 80 years old and 53.0% were over 80 years old, The nutritional risk score, as evaluated by a Nutrition Screening Initiative (NSI) checklist was 10.7 points, and the high nutrition risk group was 91.5% of the subjects. The subjective self-health status score was 2.24 points (out of a total of 5 points) and the tooth status score was 3.30 points. The physical activity level was 2.17 points for the under 80 years old group and 1.76 points for the over 80 years old, and there was a significant difference according to age (p<0.01), The higher the health status, tooth condition, physical activity and social participation activity level, the lower was the nutritional risk. Further, the higher the degree of depression, the higher was the nutritional risk. Conclusions: For the healthy life of the elderly in the community, various welfare policies should be planned to increase social participation as well as to promote physical health and reduce depression.
