The aim of this research was to examine the management practices related to foodservice.clinical nutrition service provided by hospital foodservice operations. A survey of 30 hospital food nutrition service departments was undertaken and detailed information was collected from each, including surveys of 176 dietitians and 30 foodservice managers. Statistical data analysis was completed using the SAS/win 6.11 package for descriptive analysis and t-test. The results of this study can be summarized as follows : Out of 30 hospitals, 73.3%(22) were directly operated and 26.7%(8) were under contract foodservice management. Licensed number of beds were 768.7, with an average length of 11.4 days. The general characteristics of the dietitians were that 49.4% were aged between 25-29, and 60.8% were ordinary dietitians. 76.7% had bachelor's degree, 15.9% with master's degree and 7.4% were college graduates. Most hospital dietitians had internship training and 35.2% took a training course of 6 to 12 months. The average space of kitchen was 452.52 $m^2$, with 133.63$m^2$ for modified diet space and 18.13$m^2$ for nutrition counselling room space. The total number of normal meals was 1,255.47, with 502.93 of modified meals. The average calorie of normal meals was 2,145.04kcal, with 91.9g of protein contained in normal meal. The total food waste was 351.40kg. An average monthly cost for disposing food waste was 745,171.67 won. 83.3% of the kitchens were on the 1st basement and only 66.7%(20) of 30 hospitals had its own nutrition counselling room. 80% used dishwashers and 66.7% had an exclusive elevator for delivering meals. 80.0% of hospitals used centralized delivery service. 90% had established an area for hygiene division, 70% used dry zone within the dishwashers for sterilization, 66.7% provided spoon and chopstick, and 100% used dish cover. As means of food waste treatment, most hospitals(56.7%) used animal feed by contracters, followed by means of collection by contracters(30%) and in-house high speed fermentation machines(13.3%). It was found that only 33.3% hospitals regularly checked temperatures of the meals given to patients. Total productivity index was 3.72(meals/hour) in average, with an average productivity index for normal diet of 5.41. Average productivity index for modified diet was 4.62. Productivity indices for patient meals and clinical nutrition were 5.01(meals/hour) and 1.12(cases/hour) respectively and hospitals under self-operated foodservice management received higher points on clinical nutrition productivity index(P<0.01) than hospitals under contract foodservice management.

본 연구에서는 국내 음식물쓰레기 (food waste, FW) 분야에 대한 재활용 현황을 분석하고 green house gases (GHG) 배출 관리방안에 대해 고찰하였다. 연구 결과, FW의 자원 활용성을 향상시키고 GHG 배출을 부가적으로 저감시키기 위해서는 적절한 선순환체계가 필요하다는 결론을 얻었다. 효과적인 퇴비화를 위해서 우선 GW의 활용이 고려되었다. 특히 3세대 바이오매스로써의 GW (phytoplankton, periphyton, macrophyte etc.)는 퇴비화 공정에서 FW의 단점을 보완하고 질적 능력을 향상시킬 수 있는 좋은 기능성 첨가제로 판단된다. 또 하나의 접근법은 최종산물 (예: 토양개량제)을 오염물질 완충이 가능한 bio-filter로 가공하여 그린인프라에 적용하는 방안이다. 이러한 생태공학적 접근과 시도는 안정화된 재활용 산물의 기존 활용 이외에도 FW 자원화에 대한 새로운 적용처를 제시할 수 있으므로 향후 효과적인 탄소 넷제로 (Net-Zero) 시스템 구축에 기여할 수 있을 것으로 판단된다.

Sustainable practices of school foodservices are gaining more attentions. The study aimed to investigate dietitians' performance levels of sustainable practices in school foodservice settings in Gyeonggi Provinces. Using a survey method was used, and data were collected from 358 participants (response rate 59.7%) to be analyzed using the SPSS program. The evaluation tool for sustainable practices of school foodservices consisted of four sections and 34 criteria with 100 points. Employment status of the respondents was as follows: nutrition teachers 40.9%, dietitians (permanent) 45.1%, and temporary position dietitians 13.2%. Dietitians' performance for sustainable practices marked 65.67 points out of 100 (performance rate 66%) and were in the following order by section: sustainable foodservice management criteria (69%), support activities (69%), planning and evaluation (68%), and outcome management (52%). Regarding sub-sections, criteria that acquired higher performance rates were labelling of food origin (99%), use of seasonal vegetables and fruits (98%), food waste management by contract dealer (98%), and planning for reducing of food waste and solid waste (91%). Meanwhile, criteria that showed the lowest scores were installing water conservation devices on equipment (19%), operating food donation programs for communities (21%), use of sensor lights for electricity conservation (24%), planning for annual energy conservation (40%), and implementation of education programs for foodservice workers on sustainable activities (42%). Performance scores differed according to school levels and working experience of dietitians, indicating that dietitians at elementary school foodservices or with work experience of 15 to 20 years showed higher performance than those at high schools or with less than 5 years of work experience (P<0.001, P<0.05). Based on the results, action plans for improvement were suggested.

BACKGROUND/OBJECTIVES: Sustainability has become one of the top priorities in the foodservice industry. With an increase in consumer interest in sustainability and educational opportunities in higher education, it is important to know what sustainable practices are implemented in campus dining and how sustainable practices affect consumers' responses. This study aims to identify the key sustainable practices in the campus dining context, and investigate the relationship by applying the stimulus-organism-response framework to determine whether the key sustainable practices influence consumers' perception and behavioral intentions. SUBJECTS/METHODS: The self-administered online survey was distributed to college students in 8 dining halls at a large southeastern university in the United States from September 20-October 10, 2019. A total of 382 valid questionnaires were collected, and factor analysis and multiple regressions were utilized to test the research model. RESULTS: This study identified 4 dimensions of campus sustainability with a total of sustainable practices: sustainable food, waste management, energy/water conservation, and recycling/reuse. Three dimensions of sustainable campus practices (i.e., sustainable food, waste management, recycling/reuse) played a significant role in consumers forming a perceived value while energy/water conservation did not significantly influence the consumers' perceived value toward the campus dining. Waste management was identified as the most important practice to enhance consumers' perceived value (β = 0.330). Using sustainable food and recycling/reuse were ranked second and third, respectively (β = 0.262, β = 0.154). The findings confirmed the significant positive relationship between perceived value and revisit intentions. CONCLUSIONS: The findings support the inclusion of dining sustainability as a critical component in explaining college students' perceived value and revisit intention toward campus dining. Furthermore, this study provides practical implications for university administrators and foodservice operators to consider the key sustainable practices to meet the consumers' value and revisit intentions.

This stusy was designed to develop nutrition education program for the primary school children served by the national school lunch program and to evaluate ist educational effects. Subjects consisted of 61 elementary school children(30 in the control group and 31 in the treatment group) in the 5th grade. Only the treatment group participated in a twelve-week nutrition education program. To evaluate the effects of the nutrition education program, the control and treatment groups were given a pretest and posttest for nutrition knowledge, food attitude, food habits, food preference and plate wastes before and after nutrition education. The results obtained are summerized as follows ; the nutrition knowledge test score (30.4) of the treatment group was significantly higher than that (17.4) of the control group after nutrition education . However, there was no significant difference between the two groups in food attitude test scores after nutrition education. We also did not find any difference induced by nutrition education or the food preferences of the treatment group. After nutrition education , the amount of plate waste of some menus were significantly decreased in the treatment group, but the amount of plate waste of the control group was not significantly changed. However, there was no significant difference in the post test scores above food habits between two groups. It was concluded that a twelve-week nutrition education program can improve nutrition knowledge and decrease plate waste but is not enough to change food attitude , food preference and food habits. It can besard that the two components of foodservice are nutritional foodservice and nutrition education. Foodservice management alone without nutrition education is hardly enough to improve the nutritional status of school children. The result of this study indicate that applying the nutrition education program to elementary school children who are served by the national lunch program can maximize the effects of the national school lunch program.

The purpose of this study was to examine the dietary attitudes, dish preferences, and plate waste status of elementary school students in Chungnam province. Questionnaires fearuring dietary attitudes, dish preferences, and plate waste measurements over 4 days were administered to 278 elementary school students (3~6th grades; boys 124, girls 154). Regarding plate waste of food, subjects showed the following in decreasing order: soup > vegetable > fish > kimchi > rice > meat. Regarding food preference, cooked rice showed the highest preference among rice dishes, whereas both boys and girls preferred stir-fried rice among one-dish meals. For soup, soup cooked with mear was highly preferred. However, soup with vegetables was preferred less. For meat, soy sauce-glazed chicken and bulgogi were the most preferred boys and girls. In addition, boys indicated a higher preference for most of the meat dishes than girls. Among the many types of kimchi, Chinese cabbage kimchi (Baechu Kimchi) was the most preferred. For the school meals, the served and consumed amounts by boys were higher than those of girls. However, there was no significant difference in plate waste between the boys and girls. To improve management of school meals, dietitians should understand factors that influence students' food preferences.

근래 우리나라에는 음식물류 폐기물 등 유기성 폐기물과 관련하여 두 가지 주요한 정책이 추진되었다 하나는 1995 년에 전면 시행된 폐기물 종량제이고 또 하나는 폐기물관리법에 의한 유기성폐기물의 매립금지 조치이다. 이 두 정책의 시행으로 유기성폐기물의 발생원 감량과 퇴비화 및 사료화 등 재활용 기술의 발전이라는 긍정적인 효과를 거 두고 있으나 다른 한편으로는 법률적, 재활용의 하부구조, 기술적 측면에서 음식물류 폐기물 정책을 추진하는데 걸림돌로 작용하는 잠재된 문제점도 공존하고 있다. 본 연구에서는 음식물류 폐기물 자원화 정책의 문제점을 살펴보고 이에 대한 개선방안을 제시하고자 한다.

본 연구에서는 음식점의 남은 음식물의 정의를 설정하고, 남은 음식물 저감화와 남은 음식물 재사용 근절을 위한 방안과 이러한 문제가 제대로 지켜지지 않는 원인에 대하여 관련 분야의 전문가 34인과 영업주 14인을 대상으로 면접조사 및 설문조사를 통해 남은 음식물 관리에 관한 정책적개선 방안을 제안하였다. 전문가들은 수저가 닿지 않았던 음식이라도 제공된 후 남은 음식은 재사용할 수 없다는 데 동의하였다. 즉, 수저가 닿은 김치를 포함한 모든 반찬류와 피클은 한번 제공된 후 버려야 한다. 단, 쌈채소, 고추 등의 야채류는 세척 소독 후 재사용 혹은 가열음식에 재사용하는 경우 허용된다고 응답하였다. 급식관리 전문가와 식품위생 전문가가 제공된 후 손대지 않은 채 남은 김치를 다시 재활용하거나 가열식품의 조리에 이용할 수 없다고 주로 응답한데 반해, 식품접객업 영업자들은 재활용 할 수 있다고 응답하여, 실제 음식점 영업 현장에서 김치류의 재활용 가능성이 높은 것으로 추정된다. 남은 음식 저감화가 이루어 지지 않는 원인과 남은 음식 재사용의 원인으로는 '한국적 식문화'와 '대국민 홍보부족'이 공통적인 원인으로 지적되었다. 또한 전문가들은 이 두 문제를 해결하기 위한 방안으로 '대국민 홍보'와 '소비자 및 영업 주 종사원 교육'을 통한 식생활 개선과 현장 음식문화 개선을 공통적으로 제안하였다. 과거에 음식문화 개선이 영업자 중심으로 이루어졌기 때문에 실제 소비자들의 관심과 협조를 유발하지 못한 점을 고려하면 대국민 홍보는 상당한 효과가 있을 것으로 기대된다. 소비자들이 음식물을 남기면 결국 소비자들에게도 피해가 발생된다는 점을 부각시킴으로써 소량배식 및 좋은 식단제 등을 통한 영업주측의 식문화 개선 정책 시도에 대한 소비자들의 오해와 불만을 완화시키는데 대국민 홍보가 긍정적인 영향을 미칠 것이다. 또한 전문가들은 보다 구체적인 남은 음식물 저감화 방안으로 '반찬선택제'와 '소량배식'을 꼽았으며, 남은 음식물 재사용 근절 방안으로는 '식당 내 남은 음식통 설치 의무화'를 통해 남은 음식이 식당 내로 재진입되는 것을 막을 수 있는 방안을 제안하였다. 이러한 방안들은 영업주와 종사원들의 실천의지를 전제로 식품접객업소 단위에서 적극적으로 적용할 수 있으므로 남은 음식물 관리를 위한 효과적인 방안이라 사료된다. '남은 음식 재사용 여부를 검증하는 과학적 기법 개발'은 남은 음식물의 재사용이 은밀히 이루어져 공개적인 지도와 개선이 어려운 점을 고려할 때 객관성과 과학적 근거를 토대로 한 가장 합리적이고 신속한 방안이다. 음식물에 혼입된 타액 효소의 검출을 위한 키트를 현장에 적용할 수 있다면 남은 음식물 재사용을 근절하는 가장 효과적인 해결책이 될 것으로 기대된다. 본 연구를 통해 제안된 남은 음식물 발생과 재사용 근절 방안들은 현재 한시적으로 운영되고 있는 남은 음식물 관련 정책의 향후 보완에 적용될 수 있을 것이다.

음식물 쓰레기는 산완충능(buffer capacity)이 충분하지 않아 포집과 운송기간 동안 유기산이 축적될 수 있고 몰리브덴이나 코발트와 같은 미량원소가 부족할 수 있기 때문에 가축분뇨는 음식물 쓰레기와 혼합소화 시 부족한 메탄생성량을 보충할 수 있는 혼합기질로서 적합한 것으로 판단된다. 본 논문에서는 성공적인 혐기공정 설계 및 안정적 운영을 위한 우리 나라 유래 대상기질의 실제성상 특징과 메탄가스 발생사이의 상관성을 알아보고자 하였다. 서울시의 8개 기초자치단체(강남, 강동, 송파, 영등포, 관악, 구로, 동작, 용산)의 음식물 쓰레기 중간 집하장이나 처리시설에서 음식물 쓰레기를 채취하였다. 음식물 쓰레기의 고형물 함량은 평균 16%를 보였고 잠재 메탄발생량은 평균 $446.6STP-m{\ell}/g-VS$로서 $334.8{\sim}567.5STP-m{\ell}/g-VS$의 범위를 가진다. 우분의 고형물 함량과 잠재메탄 발생량은 각각 평균 26%과 $280.6STP-m{\ell}/g-VS$로 타나났다. 잠재 메탄발생량은 고위발열량, 지방 함량, 탄소함량, 수소함량과 양의 상관관계를 가지고 탄수화물 함량과 음의 상관관계를 가지는 것으로 나타났다($r^2&gt;0.8$). 따라서 이러한 기질특성 분석결과를 통해 잠재 메탄발생량을 비교적 정확하게 예측하였다. 본 연구에서는 단일 기질과 잠재 메탄발생량을 분석하였으나 향후는 최대 메탄발생량을 위하여 혼합기질 (음식물쓰레기, 가축분뇨, 수분조절제 등)의 최적조합을 결정하는 연구가 수행하여야 할 것으로 여겨진다.
