This study was conducted to investigate the effects of mixed bone and brisket meat on the quality characteristics and nutritional components of shank bone extract and rib extract from Hanwoo. The pH values were influenced by the raw bones, mixed bone, brisket meat and their interactions (p<0.05). The salinity, sugar content, turbidity, and essential amino acid values increased significantly with addition of mixed bone and brisket meat. All attributes of sensory evaluation score were the highest in T6 (Rib 500 g + Mixed bone 500 g + Brisket meat 400 g) (p<0.05). The mixed bone significantly increased the saturated fatty acids of shank bone extract (p<0.001). Thus, the addition of mixed bone and brisket meat had a positive effect on the quality and nutritional components in shank and rib extracts of Hanwoo cattle.

Persimmon has long been established as one of the major fruits in Korea. The southern parts of Korea were traditionally the pocket areas for good persimmon production; however, rising temperatures have gradually rendered the southern regions unsuitable for successful harvest. Ecology of fruit growing areas affects the productivity of various types of crops, including fruit trees such as persimmon. The quality characteristics of the fruit of persimmon cv. Dongchul grown in Gangwondo, which lies in the northern part of South Korea, were investigated. Different physicochemical, nutritional, and antioxidant properties of fruit were evaluated to assess the locational effect on the quality of persimmon fruits grown in Gangwondo. The results of this study showed that persimmon cv. Dongchul grown in Gangwondo maintains many of the physicochemical (4.33% crude protein and 4.32% crude fiber), nutritional (total mineral content: 461.51 and vitamin C content: 15.28 ㎎/100 g), and antioxidant properties (polyphenol content: 633.1 ㎎ gallic acid equivalent/100 g) those are found in other three commercial cultivars ‘Daebong’, ‘Kyengsan Bansi’, and ‘Sangju Doongsi’ grown in Korea. Overall results of this study imply that ‘Dongchul’ cultivar of persimmon could commercially be grown in Kangwondo, Korea.

The primary purpose of this study was to investigate the job characteristics and competencies of a head-cook in contracted foodservice management company, identify the knowledge, abilities, skills and other characteristics (KASO) required to perform the duties of a head-cook, and provide training content and develop training program for job of head-cook in contract foodservice management company (CFMC). A survey instrument including identified KASO was used in the study. The questionnaire was delivered by using e-mail to 165 head-cooks employed by CFMC. The factor analysis resulted in a three-factor structure of the instrument such as 'basic foodservice operation duties' 'personal characteristics' 'managing of expanded duties-menu, customer and business'. This result suggested the education and training program for head-cook in CFMC should be composed of 'basic foodservice operation duties' on 'bulk preparation', 'procurement, inventory management', 'facility and equipment management', and 'sanitation and safety management', 'personal characteristics' on 'personality management' and 'moral duties', and 'managing of expanded duties-menu, customer and business' on 'menu management', 'customer service management', 'cost management', and 'administrative ability'. Therefore, it will be expected that the management of human resources in the contract foodservice industry would be developed by the application of recommended education and training program.

Objectives: This study examined the characteristics of patients according to nutritional status assessed by five nutritional screening tools: Patient-Generated Subjective Global Assessment (PG-SGA), NUTRISCORE, Nutritional Risk Index (NRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) and to compare the agreement, sensitivity, and specificity of these tools. Methods: A total of 952 gastric cancer patients who underwent gastrectomy and chemotherapy from January 2009 to December 2012 were included. The patients were categorized into malnutrition and normal status according to five nutritional screening tools one month after surgery. The Spearman partial correlation, Cohen's Kappa coefficient, the area under the curve (AUC), sensitivity, and specificity of each two screening tools were calculated. Results: Malnutrition was observed in 86.24% of patients based on the PG-SGA and 85.82% based on the NUTRISCORE. When NRI or CONUT were applied, the proportions of malnutrition were < 30%. Patients with malnutrition had lower intakes of energy and protein than normal patients when assessed using the PG-SGA, NUTRISCORE, or NRI. Lower levels of albumin, hemoglobin, total lymphocyte count, and total cholesterol and longer postoperative hospital stays were observed among patients with malnutrition compared to normal patients when NRI, PNI, or CONUT were applied. Relatively high agreement for NUTRISCORE relative to PG-SGA was found; the sensitivity was 90.86%, and the AUC was 0.78. When NRI, PNI, and CONUT were compared, the sensitivities were 23.72% for PNI relative to NRI, 44.53% for CONUT relative to NRI, and 90.91% for CONUT relative to PNI. The AUCs were 0.95 for NRI relative to PNI and 0.91 for CONUT relative to PNI. Conclusions: NUTRISCORE had a high sensitivity compared to PG-SGA, and CONUT had a high sensitivity compared to PNI. NRI had a high specificity compared to PNI. This relatively high sensitivity and specificity resulted in 77.00% agreement between PNI and CONUT and 77.94% agreement between NRI and PNI. Further cohort studies will be needed to determine if the nutritional status assessed by PG-SGA, NUTRISCORE, NRI, PNI, and CONUT predicts the gastric cancer prognosis.

Purpose: Malnutrition is a major concern in patients with gynecologic cancer receiving chemotherapy. The aim of this study was to evaluate the prognostic significance of malnutrition in patients with gynecologic cancer undergoing chemotherapy. Methods: A prospective, observational study was conducted on a total of 99 subjects who were treated at a tertiary hospital in Korea. Data regarding demographic, clinical, nutritional, and psychological characteristics at baseline and survival were obtained. Results: Performance status, nutritional status, depression, and annual income were significantly different between survivors and non-survivors. Multivariate Cox modeling after adjusting for other factors showed that a malnourished status in patients with gynecologic cancer undergoing chemotherapy was a significant and independent negative influencing factor for survival. Conclusion: These findings provide evidence that adequate nutritional assessment and intervention may assist in improving survival in patients with gynecologic cancer undergoing chemotherapy.

As part of the Nutrition CRSP Mexico project conducted in rural villages in highland Mexico, this study examined whether nutritional factors, family characteristics, and the duration of schooling were associated with cognitive performances in 107 schoolers(53 boys and 54 girls) aged 8~10. Food intake was measured by recall, direct observation and weighment twice monthly over the course of a year. Families were characterized in terms of socioeconomic status and parental cognitive performance, education and aspiration. Dietary quality, but not energy intake, and anthropometry (wt-for-age, ht-for-age, head circumference) were significantly associated with cognitive test results for both verbal and performance measures. When the effect of SES is controlled using partial correlation, the relationships were substantially weakened. Sex differences were also found in response to nutritional deprivation. Among boys, dietary quality was the most important indicator of cognitive performance, while household economic conditions were more importantly associated with cognitive performance among girls. Participation in schooling was important for cognitive skille as it related to nutritional status.

This study was conducted to investigate nutritional knowledge, dietary attitudes, and dietary behaviors of adult women, and to examine if these characteristics were different by acne status. Subjects were 106 adult women residing in Seoul recruited from clients and employers at skin care centers, and housewives from apartment complexes. Surrey instrument was adapted or modified based on literature review and dietary intakes were assessed using 24-hour recalls for two days and CAN-pro. All data was statistically analyzed using x$^2$test and ANOVA. When examined by acne status, 41.5% of subjects were categorized into acne group, 20.8% were as ex-acne group, and 37.7% as no-acne group. Parental experience of acne was significantly related to acne status(p〈 0.01). Education, employmental status, and smoking or drinking status were not related to acne status. Subjects had a moderate level of nutritional knowledge(72.7 point) and the nutritional knowledge store was not significantly different by acne status. When examined by individual items, the groups showed significant difference on the items regarding vitamin C and necessity of carbohydrates(p 〈 0.05). Subjects showed favorable dietary attitudes. Although the acne group showed more favorable attitudes on the importance of nutrition on acne, the overall dietary attitudes of the acne group were not significantly different from the ex-acne group or no-acne group. Similarly only small differences were noticed in dietary behaviors or nutrient intakes by acne status. Cholesterol consumption was hitgher in the no-acne group than in the acne group or ex-acne group(p 〈 0.01). The intakes of energy, iron, and calcium was much below the RDA in three groups. Although there were not many significant differences in nutritional knowledge, dietary attitudes, and dietary behaviors by acne status, this study provided some baseline information regarding study variables by acne status.
