The purpose of this study was to analyze staff satisfaction with staff foodservice in hospitals. The study compared the hospital staff's expectations and perceptions of foodservice. The quality satisfaction values were indicated as the differences between their expectations and perceptions. The subjects were 643 hospital staff in 11 Daegu . Kyungpook hospitals. Written questionnaires were used to collect the data. The completion rate was 76.9%. There were 17 attributes for foodservice quality, which were divided by factor analysis into four main quality factors; sensory, nutrition, sanitation and service. The high expectation and low perception items on the expectation and perception grid were: seasoning of the meals, taste of the meals, variety of the menu, nutritional considerations, cleanliness of the dishes, and prompt handling of meal complaints. On all the attributes measured, expectations were higher than perceptions. The quality satisfaction values were all negative. There were highly significant(p<0.001) correlations between quality satisfaction and variety of the menu(r=0.783), nutritional considerations(r=0.770), prompt dealing with meal complaints(r=0.762), cleanliness of meals(r=0.689), and courtesy of employees (r=0.653). There is a need to improve taste, menu variety, nutrition, sanitation, speed of handling meal complaints, and courtesy.

The purpose of this study was to investigate of the dietary life, nutritional status and health condition in 100 elderly living in nursing homes in Pusan area. The quality of meals served in nursing homes base on nutrient contents and the state of preferared foods was evaluated by the questionaire and the nutritional status and health condition of subjects were estimated by the analysis of serum components. The results of this study are summarized as follows: 1 Almost all subjects were aged over 70 years and poor-educated. Mean height and weight of subjects were lower than Korean average standard but Body Mass Index(BMI) of those were normal and body fat contents of females were especially high. 2. Protein, vitamin A, vitamin C and Ca intake of subjects were lower than Korean RDA. Subjects preferred pan-broiled for meats and fishes, muchim for vegetables fruits as food between meals. 3. There were no smoking and drinking in almost all subjects. All subjects have taken nutritional supplements, mainly mineral supplements. Prevalence of disease in subjects were in the following order : cardiovascular, stomach, neuralgia in males. The frequency of neuralgia in females was highest. 4. Serum levels of HDL-cholesterol, total cholesterol, triglyceride, total protein, albumin, globulin, Ca and Mg were lower than those of normal ranges. Therefore, it Is necessary to improve nutritional status of the elderly in nursing homes with by increasing the various side dishes and to develop the standard menu for those.

Objective: The main objective of this study was to determine the effect of different diets for early-weaned (EW) calves on rumen development, and how this affects fat deposition in the longissimus dorsi of adult Korean Hanwoo beef cattle. Methods: Three EW groups were established (each n = 12) in which two- week-old Hanwoo calves were fed for ten weeks with milk replacer+concentrate (T1), milk replacer+concentrate+roughage (T2), or milk replacer+concentrate+30% starch (T3); a control group (n = 12) was weaned as normal. At six months, 5 calves of each group were slaughtered and their organs were assessed and rumen papillae growth rates were measured. The remaining calves (n = 7 in each group) were raised to 20 months for further analysis. Results: Twenty-month-old EW calves had a higher body weight (BW), backfat thickness (BF), longissimus dorsi muscle area (LMA) and intramuscular fat (IMF) than the control (p<0.05). Organ growth, rumen histology, and gene expression patterns in the 6-month-old calves were positively related to the development of marbling in the loin, as assessed by ultrasound analysis (p<0.05). In the group fed the starch-enriched diet (T3), higher BW, BF, LMA, and IMF were present. The IMF beef quality score of 20-month-old cattle was 1+ for the T2 and T3 diets and 1 for the T1 diet (p<0.05). Conclusion: Papillae development was significantly greater in calves fed on high-concentrate diets and this may have resulted in the improved beef quality in the EW dietary groups compared to the control.

The objectives of this study were to investigate the current status of the Korean government-funded meal support program for low-income children through convenience stores and to evaluate the nutritional quality of the meal items available under the program. The POS data of three convenient stores where children had used their electronic meal cards most often in Seoul during January 2010 and the kinds and amounts of ingredients of the meal items available to the children were obtained from the headquarter of the convenient stores. A total of 5,081 transactions by 693 children included in the POS data was analyzed. In addition, nutritional contents of meal items, which were meal boxes (11 kinds), kimbab (13 kinds), rice balls (27 kinds), inari sushi (1 kind), and sandwiches (26 kinds), were analyzed with Can Pro 3.0. The results showed that children had purchased flavored-milk products most often. Children tended to purchase meal items together with drinks (60.9% of transactions), but some purchased drinks (27.6%) or meal items only (11.5%). Except for meal boxes, none of the meal items satisfied 1/3 of Estimated Energy Requirements of the 9-11 year-old boys per day. The average energy contents of different kinds of meal boxes, kimbabs, rice balls, and sandwiches were 619, 357, 200, and 380 kcal, respectively, and the energy content of a package of Inari sushi was 457 kcal. Vitamin C amount was found to be deficient in all the meal items, compared to 1/3 of Recommended Intake of the 9-11 year-old boys per day. The results of this study could be useful to develop nutritionally appropriate meal items for the convenient stores participating in the government-funded meal support program for children from lowincome families.

To provide approprate nutrition informatios and guidelines for the healthy school lunch program(SLP) menus, the nutritional quality of the SLP and the nutrients that affect the food cost of SLP were evaluated after analysis of recipes and food price lists of 776 menus collected from 10 elementary SLP schools in Seoul and Kyunggi province in Korea in the year of 1995. Index of nutritional quality of SLP menus were good enough, showing over 1.0 in all nutrients except vitamin A(0.86) in kyunggi province. The percent of calories from carbohydrates, protein and fat was 52%, 16% and 32%, while the polyunsaturated fatty acid/monousaturate fatty acid/saturated fatty acid(P/M/S) ratio was 1.0/0.95/1.15. On the other hand, the nutrient-cost evaluation showed that the most expersive nutrient for the RDA(Recommended Dietary Allowance) standard of SLP was origined from the cost of energy and vitamin A. In Pertary correlation analyses, the cost of SLP meals was positively asociated with energy(r=0.244, p<0.001), protein(r=0.306, p<0.001) and carbohydrate(r=0.159, p<0.001) in diet, while the most important predictor of the cost of SLP meal provides sufficient nutrients with enough calories, but fat level is somewhat higher than the suggested value from Dietary Guidelines for Koreans. These data also suggest that meals which could offer enough vitamin A might be included in SLP menus and the cost of a SLP meal can be reduced when choosing the cheap protein source food.

Two completely randomized block design experiments were conducted to evaluate the effect of gamma irradiation processing of canola meal on performance parameters of broiler chicks (Ross 308) and protein quality of canola meal. Protein efficiency ratio (PER) and net protein ratio (NPR) were measured as indices of canola meal protein quality. Samples of canola meal were tested for nutritional value after being irradiated at dose levels 10, 20 and 30 kGy. Glucosinolate content was reduced 40, 70 and 89 percent at irradiation dose levels of 10, 20 and 30 kGy respectively (p<0.01). Percent of erucic acid in total fatty acid content increased 44, 58 and 48% as a function of radiation dose (p<0.01). Dose levels did not affect feed conversion ratio (FCR) and body weight gain of chicks (p>0.05). Liver weight was decreased by irradiation dose (p<0.05). The same trend was observed for kidney weights, but this trend was not significant (p>0.05). Gamma irradiation processing of canola meal had no significant effect on $T_3$ level in blood of chickens that consumed canola meal, but $T_4$ level of chicken blood at the 30 kGy dose decreased significantly (p<0.05). PER and NPR were not affected by radiation dose level (p>0.05). Gamma irradiation seems to be a good procedure to improve the nutritional quality of canola meal.

Purpose: We compared the quality of life (QOL) and nutritional outcomes following both Billroth I (BI) and Billroth II (BII) reconstructions after a subtotal gastrectomy in order to identify which reconstruction would produce a better QOL and nutritional outcomes and to provide better follow-up management. Materials and Methods: We studied 273 patients without evidence of recurrent disease following a curative distal subtotal gastrectomy for gastric cancer. Among them, 135 underwent a BI reconstruction and 138 a BII reconstruction. The nutritional status was assessed by using levels of hemoglobin, serum albumin, iron, and vitamin B12 and by calculating the relative body weight, the body mass index, and the percentage of body fat. The QOL was measured by using the Troidl score and by treatment-specific symptoms based on the criteria, somewhat modified by the authors, of Korenaga and others. Results: There was no significant difference in QOL between the BI and the BII groups. More than half of the patients revealed anemia, regardless of the type of reconstruction. The serum vitamin $B_{12}$ level of the BII group was lower than that of the BI group. The BII group showed a tendency toward lower hemoglobin levels and serum iron concentrations than the BI group did. Conclusions: The quality of life was not impaired in most patients after either a BI or a BII reconstruction. However, both resulted in iron deficiency anemia, although the incidence was higher after a BII reconstruction. The patient's serum iron and vitamin B12 should be measured periodically and these must be administered if the measurements reveal a below normal range.

This study investigated the nutritional quality of soybean meal (SBM) fermented by Aspergillus ($FSBM_A$) and/or followed by Lactobacillus fermentation ($FSBM_{A+L}$). Both fermented products significantly improved protein utilization of SBM with higher trichloroacetic acid (TCA) soluble true protein content, in vitro protein digestibility and available lysine content, especially in $FSBM_{A+L}$. Moreover, $FSBM_{A+L}$ produced a huge amount of lactic acid resulting in lower pH as compared to the unfermented SBM or soybean protein concentrate (SPC) (p<0.05). $FSBM_A$ and $FSBM_{A+L}$ raised 4.14% and 9.04% of essential amino acids and 5.38% and 9.37% of non-essential amino acids content, respectively. The ${\alpha}$-galactoside linkage oligosaccharides such as raffinose and stachyose content in $FSBM_A$ and $FSBM_{A+L}$ decreased significantly. The results of soluble protein fractions and distribution showed that the ratio of small protein fractions (<16 kDa) were 42.6% and 63.5% for $FSBM_A$ and $FSBM_{A+L}$, respectively, as compared to 7.2% for SBM, where the ratio of large size fractions (>55 kDa, mainly ${\beta}$-conglycinin) decreased to 9.4%, 5.4% and increased to 38.8%, respectively. There were no significant differences in ileal protein digestibility regardless of treatment groups. SPC inclusion in the diet showed a better protein digestibility than the SBM diet. In summary, soybean meal fermented by Aspergillus, especially through the consequent Lactobacillus fermentation, could increase the nutritional value as compared with unfermented SBM and is compatible with SPC.

The purpose of this study was to investigate the effects of a nutrition education and exercise on nutritional status in hemodialysis patients, with regard to quality of life (QoL), and fatigue. The subjects were divided into two groups : an educated (E) group (11 men and 9 women) and a non-educated (NE) group (7 men and 22 women). The educated group received a nutrition education and a regular exercise program for 3 months. Data on anthropometric indices and biochemical parameters were obtained from medical records. Dietary habits and nutrient intake were assessed through questionnaires and three-day food records. QoL (through the SF-36 questionnaire) and fatigue (measured by a visual analogue scale questionnaire) were assessed before and after the interventions. Dietary habit scores regarding food variety and fluid intake control significantly increased (P<0.05) after the nutrition education. Furthermore, the intake of total energy, carbohydrates, Fe, and vitamin A significantly increased (P<0.05). Vitamin C intake also significantly increased (P<0.01). Hb levels decreased whereas TG levels increased in the NE group. BUN levels decreased in the E group. After the nutrition education, QoL aspects, such as feelings of pain and general health, and the total score significantly increased (P<0.05) and the level of fatigue score decreased (P<0.01). The results of this study indicate that nutrition education and exercise for hemodialysis patients provides changes in dietary habit, daily nutrient intake, biochemical parameters, QoL, and the level of fatigue. Therefore, nutrition education and exercise help improve nutritional status and QoL.

The purpose of this study is to evaluate the nutritional status of Lake Jinyang using Landsat 8 satellite image band correlated with chlorophyll-a, which is also related to algae proliferation. We selected 20 Landsat 8 images dating from 2013 to 2017, taken close to water quality measurement date when the cloud cover was less than 20 %. Based on the results of the previous studies, analyzing the correlation between chlorophyll-a, and Landsat 8 satellite image band, we selected near infrared wavelength, band 5 which is closely related to the population of algae. The nutritional status was classified using the Aizaki trophic state index (TSIm). The results of the regression equation between band 5 and the observed chlorophyll-a data was used to calculate chlorophyll-a for the image data from 2013 to 2017. The concentration of chlorophyll-a ranged from 3 to $16.1mg/m^3$. To illustrate the spatial distribution of chlorophyll-a within the lake, the chlorophyll-a concentration was divided into five grades. The images on October 14, 2014 and April 10, 2016 showed relatively high value of chlorophyll-a, while January 18, 2015 and December 6, 2016 chlorophyll-a value were below 5. The images on October 14, 2014 and April 10, 2016 were rated as eutrophic status in most areas. The results of simulating water quality for the day when the water quality was not measured resulted to an approximate value for the Panmun station while the Naedong station needed some corrections.
