Beet armyworm, Spodoptera exigua is difficult to control using chemical insecticides because of the development of insecticide resistance. Various control agents may use for eco-friendly beet armyworm managements, Entomopathogenic fungus is one of the promising control agents as an alternative to chemical control agent. At previous study we isolated a number of entomopathogenic fungi from soil samples and selected three entomopathogenic fungi, Metarhizium anisopliae FT83, Paecilomyces fumosoroseus FG340 and Metarhizium anisopliae FG344 which had high virulence against larva of beet armyworm. To select an isolate having high virulence at high temperature against S. exigua, thermophilic pest, we conducted bioassay at five different temperatures(15, 20, 25, 30, 35℃). These three isolates showed the high mortality and low LT50 at 30℃. To select substrate for mass production these isolates were inoculated(5×10⁴/㎖, 20㎖) at barley, unpolished rice, wheat bran and rice bran and incubated for 14 days at 25℃. Wheat bran showed highest conidia production of M. anisopliae FT83 and P. funosoroseus FG340 and barley was suitable for M. anisopliae FG344.

코로나 장기화 및 새로운 감염병에 대비해 지속적인 감염병 예방설계가 요구되는 현 시점에서, 의료시설 대상의 기존 감염병 예방설계는 모든 건축물에 적용시킬 수 있는 보편성을 가지지 못하며 새로운 연구 및 사례들 또한 비교 분석을 통한 개선방향의 피드백이 이뤄지지 못하고 있다. 따라서 본 연구는 새로운 감염병 예방설계의 가이드라인 및 사례 분석을 통해 일반 건축물의 기본적 설계 요소로써 적용될 수 있는 감염병 예방설계 가이드라인의 개선방향을 제안하고자 한다. 공공을 통해 보편적 위생기준이 확립되는 감염병 예방설계 구축 시스템에 따라 본 연구는 정부 및 공신력을 가진 민간기업이 주체로 연구한 감염병 예방 설계 가이드라인과 공공건축물 사례를 비교 분석함으로써 일반 건축물에도 적용할 수 있는 보편적 가이드라인의 개선방향을 제안하고자 한다. 연구는 기존 가이드라인의 분류를 참고해 도출된 계획적 측면, 제도적 측면, 프로그램적 측면, 장비 및 설비 측면으로 분류하여 분석되었으며, 각 측면에서의 개선방향을 도출하였다. 이는 뉴노멀 시대에 무분별하게 등장하고 있는 감염병 예방설계들을 분석 및 정리함으로써 개선된 가이드라인의 후속연구에 이바지할 수 있으며, 공공건축물의 예방설계 가이드라인 분석을 통해 의료시설 대상의 기존 감염병 예방설계를 극복하며 일반시설에도 도입될 수 있는 일반성과 보편성을 가지므로 지속적인 감염병 예방설계를 제공한다는 측면에서 의의를 가진다. Design for continuous infectious disease prevention is required in preparation for prolonged COVID-19 and new infectious diseases. Existing design for infectious disease prevention in medical facilities does not have universality that can be applied to all buildings, and new studies and cases are not feedback on improvement through comparative analysis. Therefore, this study proposes a direction for improvement of guidelines that can be applied as basic design elements to general buildings through the analysis of other guidelines and cases of new infectious disease prevention design. A construction system for infectious disease-prevention design establishes universal hygiene standards through the public. According to the system, the proposed universal guidelines can be applied to general buildings. Aspects were classified into planning aspects, institutional aspects, program aspects, equipment, and facilities by referring to the classification of existing guidelines. We derived improvement directions in each aspect. This study could contribute to a follow-up study on improved guidelines by analyzing and organizing designs for infectious disease prevention that have emerged indiscriminately in the New Normal era.

정지형(Ji-Hyeong Jeong),김은진(Eun-Jin Kim),김명희(Myung-Hee Kim),최미경(Mi-Kyeong Choi) 한국식품영양과학회 2013 한국식품영양과학회지 Vol.42 No.1

본 연구에서는 학교급식에서 친환경 급식의 날을 운영하는 초등학교와 중학교, 운영하지 않는 초등학교와 중학교 학생의 친환경 농산물에 대한 인식과 학교급식 만족도를 조사하여 친환경 급식의 날 운영 특성과 문제점을 파악하고 학교급식의 질과 만족도 향상에 기여할 수 있는 기초자료를 제시하고자 실시하였다. 친환경 급식의 날을 운영하는 초·중학생의 친환경 농산물에 대한 인식에서 운영교 학생은 친환경 농산물이란 유기농산물이라고 답한 비율이 높은 반면, 비운영교 학생은 무농약 농산물이라고 답한 비율이 높았다. 친환경 농산물을 선택하는 방법은 초·중학생 모두 품질인증표시를 보고 구분한다는 응답이 가장 높았다. 가정에서 친환경 농산물을 사용하는 빈도는 초등학생의 경우 친환경 급식의 날 운영교에서 매일 사용한다는 응답이 42.1%로 비운영교의 25.0%보다 유의하게 높았다(p<0.01). 학생의 친환경 급식의 날 운영에 따른 급식만족도는 친환경 급식의 날을 운영하는 초등학교와 중학교가 운영하지 않는 학교에 비해 유의적으로 높게 나타났다(p<0.05). 이상의 연구결과를 종합할 때 친환경 급식의 날을 정기적으로 운영하는 초등학교와 중학교의 학생들의 학교급식 만족도가 비운영교의 학생에 비하여 높았다. 앞으로 학교급식에서 학생들의 기호를 고려한 메뉴 개발 및 조리법의 다양화 등으로 우수하고 안전한 친환경 농산물의 사용을 보다 폭넓게 확대하는 방안에 대한 노력이 이루어져야 할 것이다. The superiority and safety of eco-friendly agricultural products are well-known. The purpose of this study is to provide fundamental data for creating a safe food culture, to improve the quality of school food services, and to increase student satisfaction with school food services. We compared the perception of eco-friendly agricultural products and food service satisfaction between students with and without exposure to a dedicated event for learning about eco-friendly products (an Eco-friendly Food Service Day) in elementary and middle school. When students were asked to define eco-friendly products, “organic products” was a highly frequent response in schools with an Eco-friendly Food Service Day, while “pesticide-free products” was a highly frequent response in school without this event. For most students, a factor in choosing eco-friendly products was a quality certification mark. Students from elementary schools with an Eco-friendly Food Service Day had a higher frequency of using eco-friendly agricultural products at home compared to students from schools without the event (p<0.01). In addition, the satisfaction with school food service was higher in schools with an Eco-friendly Food Service Day (p<0.05). These results suggest it is important to promote the use of superior and safe eco-friendly agricultural products while developing a variety of menus considering students" preferences.

본 연구의 목적은 대학생 집단 중 신입생인 1학년과 졸업반인 4학년 학생의 음주행동에 대해 탐색하고, 음주문제 영향요인을 비교하는 것이다. 조사대상은 충청권 지역에 소재한 5개 종합대학교 재학생 417명으로서(1학년 238명, 4학년 179명) 먼저 조사대상자의 음주문제 수준을 파악하였고, 음주동기, 음주규범, 금주자기효능감이 음주문제에 미치는 영향을 살펴보기 위해 위계적 회귀분석을 실시하였다. 주요 연구결과로 첫째, 1학년의 63.9%, 4학년의 71.4%가 문제음주자로 나타났다(AUDIT≥8). 둘째, 음주문제 영향요인을 학년별로 비교한 결과, 1학년은 사교동기와 대처동기, 4학년은 대처동기가 유의미한 예측요인이었다. 셋째, 음주규범의 하위변인인 기술규범과 금주자기효능감은 1학년과 4학년 학생의 음주문제에 공통적으로 영향을 미치고 있었다. 이러한 연구결과를 바탕으로 대학과 지역사회 기반의 음주문제 예방을 위한 실천적, 정책적 함의를 논하였다. The purpose of this study is to explore the drinking behavior problems and to compare affecting factors of drinking problems between the first and fourth graders of same university student group but in different development subjects and psychological social contexts. Participants were full-time 417 students enrolled at five private colleges located in Chung-cheong areas. First, we identified the level of drinking problems of the participants and Hierarchical regression analyses were conducted to examine the effects of drinking motives, drinking norms and alcohol abstinence self-efficacy on drinking problems. The main results are as follows: First, this study found that 63.9% of freshmen and 71.4% of seniors were problem drinkers(AUDIT≥8). Second, social and coping drinking motives were significant predictors in the freshmen’s drinking problems and coping drinking motives was significant in the seniors’ one. Lastly, descriptive drinking norms and alcohol abstinence self-efficacy were also significant predictors of both students. Based on major results, we discussed the drinking problems prevention strategies in college and community settings.
