The effect of adding carbohydrate-rich feedstuffs to sweet potato leaves (SPL) on silage quality was studied using a total of 180 laboratory silos. Silage quality was assessed by changes of pH, dry matter (DM), crude protein (CP) and ammonia nitrogen ($NH_{3}$-N). Pre-wilted SPL was mixed with cassava root meal (CRM), sweet potato root meal (SPM) or sugar cane molasses (Mo) at levels of 0, 30, 60 and 90 g $kg^{-1}$ (air-dry weight of additives to pre-wilted weight of SPL). Samples for assessing silage quality were collected after mixing the SPL with the additive and thereafter at 7, 14, 28 and 56 days of ensiling. There was a marked decrease in pH after 7 days and the pH remained low and stable until day 56. Addition of 60 and 90 g $kg^{-1}$ resulted in a lower pH (p<0.05) than the other treatments. The DM content of the silage increased (p<0.05) with increasing levels of additive, while there were no differences in DM with time of ensiling. The CP content of the silage decreased (p<0.05) with increasing levels of additive. The CP content did not change up to 28 days, but was lower (p<0.05) after 56 days in all treatments. The $NH_{3}$-N levels were increasing (p<0.05) with time of ensiling, and were lower (p<0.05) with additive levels of 60 g $kg^{-1}$ or higher. Also, the additive source affected the $NH_{3}$-N values, with the lowest values found for Mo. Castrated male pigs (Large White$\times$Mongcai) were used in 4$\times$4 Latin square design to study the total tract digestibility and nitrogen (N) utilisation of diets with inclusion of ensiled SPL. The diets were based on cassava root meal with inclusion of protein from either fish meal (C) or SPL ensiled with CRM (D1), SPL ensiled with SPM (D2) and SPL ensiled with Mo (D3). The digestibility of DM, organic matter (OM) and CP were higher (p<0.05), and the digestibility of crude fibre (CF) was lower (p<0.05), in diet C than in diets D1, D2 and D3. However, there were no differences (p>0.05) in digestibility of dietary components between diets D1, D2 and D3. Also, the excretion of N in faeces was higher (p<0.05) and the N retention was lower (p<0.05) in diets D1, D2 and D3 than in diet C. It can be concluded from the present experiments, that a good quality silage can be produced from pre-wilted SPL by addition of 60 g $kg^{-1}$ of either CRM, SPM or Mo. Diets with inclusion of 450 g ensiled SPL $kg^{-1}$ DM showed a high digestibility of dietary components and thus ensiled SPL should be considered as a potential feed resource for growing pigs.

The purpose of this study was to compare student's satisfaction with school food service environment to improve the quality of middle school meal service. A survey was conducted of 680 students (boys 246, girls 433) from 6 middle schools providing school meals from October to November 2007. The questionnaires were directly distributed to the subjects for comparison of satisfaction of school meals depending on the eating place. As for the quantity of food, classroom group (3.40) expressed significantly higher satisfaction than cafeteria group (3.16, P < 0.01), but as for the satisfaction on hygiene, classroom group (2.76) showed significantly lower satisfaction than cafeteria group (3.03, P < 0.01). About the satisfaction of school meal environment, classroom group showed more satisfaction on distribution time, eating place, eating atmosphere (P < 0.001). The classroom group showed higher satisfaction than cafeteria group in cases of quantity, diversity of types of soup, dessert, and the cost of school meal. To improve eating place and hygiene of school meal, sufficient cafeteria space and pleasant environment is needed to be established.

The study on the nutritive value and the potential use of two kinds (local vs. import) of sesame meal (SSM) in layer diets as substitute for soybean meal (SBM) at 25, 50, and 75% was carried out. Three hundred and thirty six layers were kept individually on a battery cage and fed isonitrogenous diets, 16% crude protein (CP), for 252 days. The local and the imported SSM contained on air dry basis 35.7 and 36.3% CP, 24.7 and 9.1% ether extract (EE), respectively. Their amino acid contents are all lower than those reported by NRC (1984). The local material contained remarkably lower lysine (0.44 vs. 0.94), methionine + cystine (1.06 vs. 1.75) and threonine (0.52 vs. 1.22) than the imported meal. Imported SSM could be substituted for SBM as high as 50% in layer ration without statistically adverse effect on egg production, feed intake, body weight gain, average egg weight and egg size, while local SSM was inferior to the control in all aspects. However, when production performance of the groups fed either kind of SSM was compared, no significant difference was found at the two lower substitution levels.

This study investigates and analyzes the diversity of menu in military meal services that are recognized by the soldiers who are familar with meal services, and suggests the implications on the results of the analysis. For the ranks of respondents in terms of demographic features, the sergeants and corporals were 43.2%(186) and 29.7%(128) apiece. It was identified that the diversity of menu and significant influences as 57.5%. Thus, it is necessary to diversity the menus more than the present menus to increase the satisfaction of new generation on military meal services. The most influential factor on the diversity of menu was the hard-boiled food as 29.9% among 15 items. Therefore, the first measure to intensify the satisfaction of soldiers on meal services is to diversity the hard-boiled food. Accordingly, this measure will contribute to relieve the most biggest complaints on the diversity of menu in military meal services. For this purpose, it is recommended to replace the kitchen work system consisted of kitchen polices with the non-officer system enabling the long-term service. The kitchen polices are transferred to the first reserve list when they are accustomed to their duties because the period of service is limited under the present kitchen police system. Therefore, the present kitchen police system has the problem that it can't overcome the limit in terms of the quality of meal service.

Purpose: BTS Meal at McDonald's was launched in May 2021 in selected countries all over the world. BTS fans in Indonesia bought the BTS Meal and collectively donated to the online delivery drivers as a form of empathy. As a quantitative study, this paper aims to identify the influencing factors in sociopsychology for fans to buy products (BTS Meal) available online using celebrity endorsement strategy, as well as demonstrating social empathy as an extended effect. Research design, data and methodology: empirical research was conducted through an online survey sent to 150 participants using the purposive sampling method. Participants were BTS fans, or ARMYs, who bought BTS Meal and conducted donations. Data were then sorted and processed with path regression. Results: preference and role model influenced the buying behavior; however, these factors influenced social empathy only when mediated by consumption. Preference and role model alone did not have a direct influence on social empathy. Conclusions: Consumer behavior insight is relevant in distribution science. A meal distribution involving brand ambassadors is considerable, particularly with celebrities demonstrating quality in capturing fans' hearts through role modeling. When a distribution is conducted online using a brand ambassador, buying behavior could lead to a social impact.

Two experiments were conducted to investigate the effects of the addition of ginseng meal to distillers feed on the silage quality, and feed intake and dry matter (DM) digestibility in goats. In Experiment I, three levels of ginseng meal (0.15, and 30%) were added to the distillers feed to make three types (treatment) of distillers feed silages (DFS), There were five replicates per treatment. Samples of 20 kg each were put into vinyl bag and vacuumed by an air compressor. Vinyl bags were kept at $20{\sim}25^{\circ}C$ for 30 days before being analyzed. In Experiment II, 12 male Korean native goats were employed to investigate the DM intake and digestibility of silages from Experiment I. There were 4 replicates per treatment. Daily feed intakes and fecal excretion were measured. In Experiment I, the silage pH decreased and the lactic acid increased significantly by the addition of ginseng meal (P

Improved nutritional intake contributes to maintaining health and quality of life in elderly population and also reducing individual and social medical costs. Most of nutrition assistance programs for elderly, such as congregate or home-delivered meal programs, are not currently serviced in rural communities mainly due to low cost efficiency of program operation. However, the needs and necessity of such programs are presumed to be higher in rural area where the population density of elderly at nutritional risk is relatively high. Therefore, the purpose of this study was to develop a community-based meal program for the rural elderly. In 2007, four rural communities located in Jeon-Nam province were selected and the pilot meal program was applied for three months. Following are key features of the meal program model developed in this study: 1) meal production and service are operated by elderly participants to overcome the voluntary personnel shortage 2) utilization of locally-produced foods is maximized to reduce the meal cost, 3) traditional cooking methods are applied to adjust the food preference of elderly, and 4) foods are serviced on site to minimize the food safety problem possibly caused by delivery process. The pilot programs resulted in high satisfaction with the programs of participating elderly. The community-based meal program model developed in this study is expected to be used as an effective nutrition and health intervention model for the rural elderly.

It is generally accepted that diet modification provides beneficial effects on the management of diabetes. In the present study, we evaluated the effects of diet modification on nutrient intake and quality of life in a large sample of diabetic patients. This study was conducted using data from the Korea National Health and Nutrition Examination Survey IV and V (2007-2010). A total of 2,484 of diabetic patients were included in the analysis. Then, we compared the overall quality of dietary intake between diabetic patients with diet modification and those without dietary modification. The result showed that subjects on diabetic diet (DDG) showed lower levels of total cholesterol, triglyceride, and AST before and after the adjustment for covariates (all p < 0.05). The results of nutrient assessment showed that DDG had lower intakes of total energy, fat, and carbohydrate (all p < 0.05), but higher intakes of energy from protein, vitamin B1, vitamin B2, niacin and vitamin C than NDG. (all p < 0.05). In addition, nutritional adequacy ratio of calcium and vitamin B2 were significantly higher in DDG than those in normal diet group (NDG) (p < 0.05). However, we observed no significant differences in quality of life between two groups. In conclusion, diet modification in diabetic patients seemed to be effective to improve blood lipid profile and the adequacy of nutrient intake without sacrificing the quality of life.
