Objectives: This study investigated the improvement of food habits and eating behavior of cancer patients during treatment through the continuous nutrition counseling and monitoring. Methods: Thirty cancer patients during treatment were participated in this study, and the first nutrition counseling and the first and second monitoring were conducted after 2-3 week intervals. Results: As a result of the nutrition counseling and monitoring, all patients improved to a great extent to consume 3 meals a day. The frequency of having breakfast was significantly increased with the nutrition counseling and continuous monitoring as well. The meal fixed quantity was stabilized and the eating speed slowed down as more nutrition counseling were done. The snack intakes of patients did not show any significant difference after the nutrition counseling but showed a slight decline after the monitoring. The frequencies of eating out and a late-night meal significantly decreased after the monitoring. The intakes of fish, meat, vegetables, milk and fruits needed for a well-balanced diet significantly increased as more nutrition counseling were done. The intakes of processed food were significantly decreased after the nutrition counseling and the intakes of fast food were significantly decreased as more nutrition counseling were done. The water intake of patients also significantly increased. In the eating behavior related to health, the frequency of drinking alcohol significantly decreased after nutrition counseling consultation and no patients had dietary supplements after the first monitoring. Conclusions: These results suggested that continuous nutrition counseling is effective in improving eating habits of cancer patients.

Freeze-drying process was used for 10 major protein foods referred by the Korea Health Statistics 2011 as follows; chicken, pork, beef, eggs, tofu, squid, soybean, mackerel, anchovy, and pollack/frozen pollack. Boiled samples and re-hydrated samples after freeze-drying were prepared for analysis. The weight variation, the chromaticity, the mechanical texture and sensory properties by eight trained panelists were measured. In the ratio of re-hydration, the anchovy showed the highest value(89.40%), followed by eggs, and squid showed the lowest value(35.51%). Changes of Hunter color value were observed among all samples. For rates on changes of hardness, every sample was increased except for eggs(p<.05). Among the 9 samples, except for eggs, chicken showed the lowest rate of increase in hardness(125.44%) while squid showed the highest rate of increase in hardness(1335.1%). Except for eggs and pork, eight samples represented differences in sensory properties, especially in juiciness and tenderness(p<.05). As a result, we found that egg is the most suitable for freeze-drying among 10 protein sources followed by pork and chicken.

BACKGROUND/OBJECTIVES: Consumption of pine nut oil (PNO) was shown to reduce weight gain and attenuate hepatic steatosis in mice fed a high-fat diet (HFD). The aim of this study was to examine the effects of PNO on both intestinal and hepatic lipid metabolism in mice fed control or HFD. MATERIALS/METHODS: Five-week-old C57BL/6 mice were fed control diets containing 10% energy fat from either Soybean Oil (SBO) or PNO, or HFD containing 15% energy fat from lard and 30% energy fat from SBO or PNO for 12 weeks. Expression of genes related to intestinal fatty acid (FA) uptake and channeling (Cd36, Fatp4, Acsl5, Acbp), intestinal chylomicron synthesis (Mtp, ApoB48, ApoA4), hepatic lipid uptake and channeling (Lrp1, Fatp5, Acsl1, Acbp), hepatic triacylglycerol (TAG) lipolysis and FA oxidation (Atgl, Cpt1a, Acadl, Ehhadh, Acaa1), as well as very low-density lipoprotein (VLDL) assembly (ApoB100) were determined by real-time PCR. RESULTS: In intestine, significantly lower Cd36 mRNA expression (P<0.05) and a tendency of lower ApoA4 mRNA levels (P = 0.07) was observed in PNO-fed mice, indicating that PNO consumption may decrease intestinal FA uptake and chylomicron assembly. PNO consumption tended to result in higher hepatic mRNA levels of Atgl (P = 0.08) and Cpt1a (P = 0.05). Significantly higher hepatic mRNA levels of Acadl and ApoB100 were detected in mice fed PNO diet (P<0.05). These results suggest that PNO could increase hepatic TAG metabolism; mitochondrial fatty acid oxidation and VLDL assembly. CONCLUSIONS: PNO replacement in the diet might function in prevention of excessive lipid uptake by intestine and improve hepatic lipid metabolism in both control diet and HFD fed mice.

BACKGROUND/OBJECTIVES: With the advances in technologies, self-service kiosks at foodservice operations are becoming a new way of service provision. This study examined the relationships among the menu information quality, nutrition information quality, technology acceptance characteristics, and customer behavioral intention toward the kiosks in fast food restaurants. SUBJECTS/METHODS: A survey with a self-administered method was distributed online and offline. The sample consisted of customers who had used the kiosks at fast food restaurants in the last six months prior to the survey. The study hypotheses were tested by applying structural equation modeling. RESULTS: Structural equation modeling revealed the positive impacts of menu information quality and nutrition information quality, technology acceptance characteristics, and behavioral intention toward kiosks at fast food restaurants. On the other hand, one hypothesis (Hypothesis 4) on the impact of nutrition information quality on the perceived usefulness was rejected. CONCLUSION: The study is the first to investigate nutrition and menu information at foodservice kiosks and relate them to technology acceptance. The study is very timely and adequate in the time of the 4^th industrial revolution. The critical importance of the presentation of nutrition information and menu information at the kiosks at fast food restaurants was verified. The academic and industrial implications of the study findings were discussed.

The purpose of this study was to investigate self-perception and practices of health and appearance, health-related lifestyles and dietary behaviors of college students(137 male, 115 female) attending web class via the Internet. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. The average height, weight and BMI of the male and female college students were 174.4cm, 67.8kg, 22.3kg/㎡ and 162.3cm, 52.1kg, 19.8kg/㎡, respectively. Male collage students perceived their health statuses significantly better compared to female students. As for self-evaluation of anemia, female college students perceived significantly more anemia symptoms compared to male college students. Female college students perceived their body image to be obese compared to male college students. Underweight college students perceived significantly less healthy statuses, more anemia symptoms, and worse hair conditions compared to other college students. The rate of male students who exercise was significantly higher compared to that of female students. Male students reported significantly more smoking and drinking of alcohol compared to female students. The rate of female college students skipping meals was significantly higher than that of male college students. Frequency of eating out in female college students was significantly higher compared to that in male students. These results may provide some basic information in developing a nutrition education program for Korean college students using Internet.

This study was designed to investigate the difference in the autonomous supervision and role performance according to the socio-demographic factors of the teachers. Also, the relation of the autonomous supervision and the role performance was examined. This research was conducted using the questionnaire to 394 teachers of national, public, and private kindergarten in Chung-buk province. Data were analyzed with the SPSSWIN program by the frequency, percentage, t-test, ANOVA, Scheffe post-hoc test and Pearson's correlation analysis. The results were summarized as follows: First, levels of autonomous supervision of kindergarten teachers were high in general and there were significant differences according to the institution, age, scholastic ability, and the career. The accomplishment in the public kindergarten was higher than that in the private one. Moreover, the higher the teacher's age, career, and scholastic ability, the higher the accomplishment. Second, levels of role performance of the kindergarten teachers were excellent, but the levels of role performance were higher in the public kindergarten than in the private one because the public teachers who did not transfer much had more chances of continuous education and higher responsibility. The role performance of teachers was found to be relatively higher in the kindergarten in countries than in cities because there were more public kindergartens than private ones in countries. Third, there were significant correlations between the lower factors of autonomous supervision and the role performance of the kindergarten teachers. Because the various types of the autonomous supervision can help the teacher's role performance, various types of the autonomous supervision which fit the developmental stages of the teachers will be desirable.

The objective of this research was to analyze nutritional status and food consumption of children participating in the Posyandu nutrition program. A total sample of 300 children under five years had been drawn. Sample was divided into two categories namely high participation and low participation in the Posyandu nutrition program. The sample was selected from two sub districts of Cianjur District, West Java. The districts were areas with a high proportion of poor people and many of them take the benefits of Posyandu nutrition program conducted by the government. The participation of children (under five years old) in visiting Posyandus was relatively good, namely, 92.4% (for the high participation group). However, for the low participation group, the number of participating children was relatively low (28.3%). The average consumption of energy for children under five years old was still below the recommended dietary allowance < 80% of RDA, whereas the protein consumption was already above the RDA. The prevalence of underweight, stunting, and wasting among children were respectively 30.0%, 43.7%, and 12.3%. The activities at Posyandus had a positive impact on the nutritional status of children under five years olds, measured in terms of weight for age (W/A) and weight for height (W/H). The more frequent the visit to Posyandus, the better the nutritional statuses would be.

In this study, antioxidative and anti-inflammatory activities of the herb (cinnamon, clove, glehnia root, ginger, violet-root cromwell, licorice, citrus peel and longan) extracts used for gamhongroju, one of the popular liqueurs in Korea, were investigated. Twenty grams of individual herbs were extracted in 60% purified ethanol and freeze-dried. A mixture of the individual herb extracts (HEM) was separately prepared. Cytotoxicity of the individual extracts and HEM on murine RAW264.7 macrophage cells were examined along with their recovering activity on $H_2O_2$-treated RAW264.7 cells. Antioxidant and anti-inflammatory activities of the extract-treated cells were determined by measuring superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities, and Trolox equivalent antioxidant capacity (TEAC), nitric oxide (NO) and prostaglandin E2 (PGE2) levels. Violet-root cromwell extract showed the least cytotoxicity in terms of treated concentration. Most of the extracts, below levels of cytotoxicity, recovered the $H_2O_2$-treated cells. Treatment with some of the extracts increased SOD and GPx activities and TEAC levels while a majority inhibited the production of NO and PGE2 in lipopolysaccharide (LPS)-treated cells.

The changes of resistant starch (RS) contents of cooked rice with soybean and coconut oils under different storage conditions were investigated and RS contents were compared between the rice and cooker types. The japonica (Hopyeong) and the indica (Thailand) type rice were cooked (washed rice: water = 100: 130) using an electric cooker and a saucepan. The coconut oil and soybean oil (3%, based on rice, w/w) were added into cooking water before heating. The RS contents of freeze-dried cooked rice powders (newly-cooked rice, stored for 12 h in the refrigerator, microwave heating after storage for 12 h in the refrigerator) were measured by the AOAC method. The RS contents of cooked rice using a saucepan were higher than those using an electric cooker. The indica type cooked rice had a higher RS content than the japonica type cooked rice, regardless of storage conditions. However, addition of oil before cooking rice resulted in increased RS content on storage in the refrigerator. The highest RS content of the cooked indica type rice with soybean oil ($5.89{\pm}0.22%$) that was stored for 12 h in the refrigerator was analyzed. The results suggested that the cooked rice formed retrograded (RS3) and amylose-lipid complex (RS5) type RS; furthermore, the RS content is affected by storage conditions, rice, cooker and oil types.

In spite of the reported probiotic effects, Bifidobacterium bifidum BGN4 (BGN4) showed no βglucosidase activity and failed to biotransform isoflavone glucosides into the more bioactive aglycones during soy milk fermentation. To develop an isoflavone-biotransforming BGN4, we constructed the recombinant B. bifidum BGN4 strain (B919G) by cloning the structural β-glucosidase gene from B. lactis AD011 (AD011) using the expression vector with the constitutively active promoter 919 from BGN4. As a result, B919G highly expressed β-glucosidase and showed higher β-glucosidase activity and heat stability than the source strain of the β-glucosidase gene, AD011. The biotransformation of daidzin and genistin compounds using the crude enzyme extract from B919G was completed within 4 h, and the bioconversion of daidzin and genistin in soy milk during fermentation with B919G also occurred within 6 h, which was much faster and higher than with AD011. The incorporation of this β-glucosidase-producing Bifidobacterium strain in soy milk could lead to the production of fermented soy milk with an elevated amount of bioavailable forms of isoflavones as well as to the indigenous probiotic effects of the Bifidobacterium strain.
