The purpose of this study was to investigate the perception of the school dietitian on superior agricultural products (SAP) and the status of using superior agricultural products in school meals. Questionnaires were distributed to 185 school dietitians after face to face interview, and a total of 181 responses were used for analysis. 82.3% of the respondents were using SAPs in school meals and there was a significant difference between elementary school (95.1%), middle school (76.8%) and high school (66.7%) dietitians (p < 0.001). 85.2% of the dietitians, who were using SAP, were purchasing SAPs through electronic bidding, and the main reason of not using SAPs was the higher price of SAPs than that of general agricultural products. The good agricultural practices (GAP) product was considered the most appropriate agricultural products for school meals by the majority of respondents (66.9%), and organic products was the next (13.3%). In addition, the most important selection criterion for a SAP perceived by school dietitians was safety (58.0%), and the main reason of using SAPs in school meals, when two choices were allowed, was 'to provide healthful food to children' (98.9%). The major barriers to using SAPs in school meals (two choices were allowed) were 'too expensive' (73.5%) and 'unstable supply' (32.6). In conclusion, it was suggested that there should be an improvement in SAP supply and management systems to increase the use of SAPs in school meals.

The purpose of this study was to investigate middle school students' perception of environment-friendly agricultural products (EAPs) and the degree of confidence about the certification mark. Questionnaires were distributed to 444 students of 6 middle schools located in Daegu, and a total of 416 responses were used for analysis. 28.6% of the respondents were using EAPs at home, and 62.0% of respondents didn't know whether to use EAPs at home. The 6 items representing the perception of EAPs were analyzed, resulting in 2 distinct dimensions-'benefits of EAPs' and 'attitude toward EAPs'. Regarding Benefits of EAPs, the score of 'EAPs better for health' was the highest, followed by 'EAPs have higher quality', 'EAPs were better for environmental protection', respectively. The proportion of students responded that 'the amount of pesticides should be reduced gradually' was 65.5% and only 3.4% for 'current level of pesticide use is not a problem'. There were significant differences between male and female students with regard to an interest in EAPs (p < 0.05) and opinion on the use of pesticides (p < 0.05), while no significant difference was found between groups with different education level of mothers. The respondents who use EAPs at home showed significantly higher scores with attitude toward EAPs (p < 0.001), and higher response rate for 'pesticides should not be used even if the price increases' (p < 0.05). Degree of confidence about the EAPs certification mark also affected students' perception of EAPs (p < 0.001). Our results indicate the importance of education for students on EAPs to enhance students' attitude towards EAPs and improve school meal satisfaction.

In this paper, weight, carcass dressing, weights of the primary cuts, weights of the physical components of the primary cuts, and weights of the main commercial cuts of 66 $Purun{\tilde{a}}$ animals, of which 33 were bulls and 33 were steers were evaluated. These animals, with an average age of 19 months at the beginning of the experiment, were finished in a feedlot system during 116 days, and were fed with diets containing three levels of concentrate (0.8%, 1.1%, and 1.4% of body weight). The concentrate was formulated with 25% soybean meal, 73% ground corn grain, 1% of a mineral mix, and 1% of limestone. The interaction between sexual groups and the concentrate level was not significant for any of the variables. Likewise, no effect of the concentrate level was detected on the same variable traits. The bulls demonstrated higher hot carcass weights (265.1 vs 221.7 kg) and a higher proportion of forequarter (38.4% vs 36.1%) however the steers presented with higher proportions of side (19.7% vs 18.5%) and hindquarter (44.2% vs 43.1%). The bulls produced higher yields of muscle in the three primary cuts, there by resulting in higher yields of edible portions of the carcass. The bulls also produced higher weights of tenderloin, knuckle, topside, flat, eye round, rump, and rump cover. The finishing of young bulls in feedlot is to be recommended, since the animals produce carcasses with higher amounts of edible meat and higher yields of commercial cuts, thus allowing for a better price for the carcass. Low concentrate level could be used due to the lower cost of production for farmers.

Background: High demand and low supply of fishmeal due to overexploitation of fisheries resources have resulted in a dramatic increase in the price of this ingredient. Olive flounder (Paralichthys olivaceus) commercial feed contains approximately 60% fishmeal and limited success has been achieved in identifying sustainable alternative protein sources for this species. Methods: An on-farm feeding trial was conducted to compare a basal diet containing 65% as the control (CONT) with two experimental diets replacing 10% of fishmeal by animal protein (AP₁₀) or 20% of fishmeal by animal and plant protein (APP₂₀). Sub-adult olive flounder averaging 327 ± 9.3 g (mean±SD) were fed one of the three diets in triplicate groups for 16 weeks. Results: Weight gain, specific growth rate, feed efficiency, protein efficiency ratio, and survival were not significantly different among fish fed all the experimental diets (P > 0.05). Also, non-specific immune responses (superoxide dismutase and lysozyme activity), serum biochemical parameters, and intestinal villi length were not significantly different among fish fed all the experimental diets (P > 0.05). Conclusions: Therefore, based on growth performance, non-specific immune responses, serum biochemical parameters, and intestinal histology, dietary animal and plant protein mixtures could replace up to 20% of fishmeal in the diet of sub-adult olive flounder.

In order to obtain the information on the status of using university cafeteria and students' preferences, the survey was conducted through questionaires to 434 students(male:195, female : 239) of 8 universities - 2 universities employed dietitian and 6 universities which didn't employ dietitian -through all the area of Incheon from 19th November 1990 to 14th December, 1990. The results obtained were as follows. 1) For keeping temperature of meals until service to students Refrigerator or warming cabinet or putting meals on low flames were used, and the amount for one person was almost decided by rough estimation by experience. All the foods remained were discarded. Also most of the cooking manager's age were from 50 to 59 and almost cooking managers graduated middle school. The fuel to cook was gas or kerosene. Method to disinfect tableware was boiling. 2) In case of the frequency of using university cafeteria, male students used cafeteria more often than female students, and regardless of sex students made use of cafeteria for lunch more than for breakfast and supper. Students also used university cafeteria not employing dietitian more than cafeteria employing dietitian. Disregarding of male, female, cafeteria employing cafeteria not employing dietitian, all students pointed out that main reason for using cafeteria were 'low price' and 'no other place to eat' And minor reasons were ' good taste' and 'meal quality'. On the contrary, the case of not using cafeteria were 'waiting in line' to male students, 'poor taste' to female students, 'waiting in line' and 'no varieties' on the cafeteria which employed dietitian, 'poor taste' and 'poor hygienes' on the cafeteria which didn't employ dietitian. 3) Considering of the preferences of menu, both male and female students liked "Bibim Bab" And male students prefered meals which contained broth both but female students prefered a light meals. 4) the difference of preferences showed that female student's preferences were high at all foods, and the preferences of fruits were high for both students. In detail, male students liked port, liver and small intestine of cattle, oyster and beans boiled in soysauce. But female students likde milk, yogurt and cucumber.

This study aimed to investigate the use of environmentally friendly agricultural products (EFAPs) in Chungcheongbuk-do and the perception and satisfaction of school dietitians with EFAPs. The study survey was conducted from April to Jun 2018. Among 195 dietitians, 54.4% were nutrition teachers and 51.3% were working in elementary schools. Of the participants, 65% answered that the percentage of EFAPS in the total food cost was 10~30%. The most used EFAP food group was grains (64.6%), followed by vegetables (26.2%). The main reasons for using EFAPs were subsidies for EFAPs from local governments (85.1%) and students' health (52.3%). The average daily subsidy for EFAPs from the local governments was 201~500 won at 45.1%, and 200 won or less at 34.9%, which was based on one meal per student. In questions on satisfaction with using EFAPs, satisfaction with safety (3.93 out of 5 points) scored the highest, followed by nutrition (3.74), freshness (3.70), appearance (3.32), diversity (2.85), and price (2.78). Therefore, to expand the use of EFAPs in school food service, it is necessary to expand the provision of subsidies and increase EFAP production diversification.

This study examined the nutritional information using the nutrition labels of gimbap sold at convenience stores and evaluated nutritional adequacy compared to dietary reference intakes for Korean adolescents. Thirty gimbaps (triangular gimbaps and regular gimbaps according to the main ingredients of vegetables, fish, and meat) were purchased at five convenience stores of different brands with many stores in Korea. The food and nutrition labels of the gimbaps were investigated, and nine minerals were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). The average price of gimbap was 1,906.7 won, and average energy was 292.0 kcal, and the protein content was 15.5% of the recommended intake for Korean male adolescents aged 15~18 years. The mineral content ranged from 6.9% for zinc to 39.0% for selenium. Except for sodium and selenium, the energy, protein, and mineral content did not meet 1/3 of dietary reference intakes for adolescents. For the index of nutritional quality (INQ), calcium and zinc were the lowest in the triangular and regular gimbap, respectively. The INQ of potassium was significantly higher in triangular gimbap with vegetables. The content and INQ of selenium were in regular gimbap with fish, and the zinc INQ was in regular gimbap with meat. Overall, gimbap sold in convenience stores has a high sodium content, and the contents of energy, protein, and minerals, except selenium, are insufficient for a single meal.
