The purpose of this study were to analyze the staple food consumption trend of Koreans using KNHANES(Korea National Health and Nutrition Examination Survey) data. Nutrient intake of 38,840 participants of 1998~2008 KNHANES, over 6 year old were analyzed. For the analysis of major staple food intakes, twenty four hour recall data was used. The results were analyzed by SAS Program, as follows. Despite westernized diet, ranking in the primary energy source of food showed similar patterns. But total calory intake was reduced over the past 11 years and percentage of carbohydrate intake was increased. Relative proportions of protein and fat intake was reduced. The major carbohydrate and protein source of Koreans was rice and grains. Pork and ramen were the major fat source food. Although intake levels were different by gender, age and areas, carbohydrate of rice was primary source of energy in Korea.

The purpose of this study was to provide the fundamental information for establishing the database needed to estimate total intakes of trans fatty acids in Korea. The amounts of trans fatty acids contained in 164 samples including 25 samples of margarines, 21 samples of shortenings, 19 samples of vegetable salad and cooking oils, 53 samples of confectionery products, 18 samples of bakery products, 19 samples of dairy products, and 9 samples of animal fats and meats were analyzed by capillary gas liquid chromatography. The average amounts of trans fatty acids in those foods were calculated and expressed as gram per one serving. Then, the average daily intakes of trans fatty acids per capita were estimated using the analyzed amounts of trans fatty acids and the amount of yearly production for those foods. The amounts of trans fatty acids per 100 g of lipids were $2.11{\sim}33.83%$ (14.66% on average) in margarines, $1.47{\sim}44.48%$ (14.21% on average) in shortenings, $0.18{\sim}3.82$ (1.54% on average) in vegetable salad and cooking oils, $0{\sim}45.81%$ (10.92% on average) in confectionery products, $0{\sim}18.32%$ (7.87% on average) in bakery products, $0.90{\sim}4.54%$ (2.27% on average) in dairy products, and $0.61{\sim}6.07%$ (2.24% on average) in animal fats and meats. Major isomers of trans fatty acid in the sample foods were $C_{18:1}$ and $C_{18:2}$. As a result, the korean average daily intake of trans fatty acids in korea was estimated to be 2.3 g per capita. The amounts of trans fatty acids consumed from each selected food were as follows: 0.35 g from margarines, 0.57 g from shortenings, 0.11 g from vegetable salad and cooking oils, 0.65 g from confectionery products, 0.07 g from bakery products, 0.14 g from dairy products and 0.21 g from animal fats and meats.

고속도로 및 편의시설 건설로 불투수층의 면적이 증가하여 강우 시 고속도로 및 편의시설에서 발생하는 오염원에 의한 하천의 수질 영향도 커지고 있다. 특히 휴게소에서는 자동차의 급가속, 급감속으로 더욱 많은 분진과 오염물질이 발생할 수 있으며 타이어 마모 입자, 자동차 배기가스, 중금속 및 오일류 등이 휴게소나 도로 지표에 집적되어 있다. 이렇게 발생한 오염물질은 우기에 강우와 함께 불투수면을 침투하지 못하고 배수로를 통해 유출되어 인근 하천의 수생태 및 토양의 주요 오염원으로 작용하고 있다. 이에 따라 고속도로 및 인근 휴게소의 비점오염 저감대책이 필요하며 효율적인 비점오염원 저감을 위해 장기적인 모니터링, 지속적인 자료 수집 및 분석이 필요하다. 본 연구에서는 강원지역 고속도로 및 인근 휴게소에서 강우 시 강우유출수 모니터링을 통해 강우유출수 유량가중평균농도 (Event Mean Concentration) 산정하고 강우유출수 수문곡선 (hydrograph)을 작성하였다. 또한 강우사상에 따른 분석항목별 초기세척효과(First Flush Effects)와 오염부하량을 산정하였다. 추가적으로 차량 기인 입자를 확인하기 위해 μ-FT-IR 현미경 분석 실험을 하였다. 모니터링 장소는 휴게소 및 고속도로 일원이며, 모니터링은 선행무강우일수 2일 이상, 강우량 10mm 이상일 때 실시하였으며 2022년 6월부터 10월까지 총 4회 실시하였다. 모니터링 결과 타이어 및 브레이크 패드 마모와 관련된 중금속인 Zn, Cu, Pb 등의 중금속이 높게 분석되었으며 이러한 중금속의 오염부하량 역시 높게 산정되었다. 강우유출수 수문곡선에서 강우 초기 오염물질의 세척효과가 나타났다. MFFn 산정 결과 강우 30% 구간에서 초기세척효과를 보였다. μ-FT-IR 현미경 분석 결과 PE (Polyethylene)가 가장 많이 검출되었고 PP (Polypropylene), PS (Polystyrene) 순으로 검출되었다. 이러한 강우유출수 모니터링 데이터는 향후 고속도로 휴게소 및 고속도로 주변 오염저감 시설 설치 및 사회적 동참을 위한 타당한 근거 확보를 위한 기초자료로서 제공될 수 있을 것이다.

세계적 규모의 팬데믹 감염병의 출현은 전 세계적으로 경제적, 문화적, 사회적 파급효과가 매우 강력하며 전 인류를 위협하고 있다. 최근에 발병한 중증급성 호흡기질환 코로나바이러스 2(Severe Acute Respiratory Syndrome Coronavirus 2, SARS-CoV-2)는 2019년 12월 중국 우한에서 첫 보고 되었고 2022년 현재까지 종식되지 않고 있으며 바이러스의 전파력과 치명률이 높고 무증상 감염상태일 때에도 전염이 가능하여 현재 역학조사의 사후적 대응에 대한 한계가 있어 선제적 대응을 위한 수단이 필수 불가결해지고 있는 실정이다. 하수기반역학(Waste Based Epidemiology, WBE)이란 하수처리장으로 유입되기 전의 하수를 분석하여 하수 집수구역 내 도시민의 생활상을 예측하는 것으로 하수로 배출된 감염자의 분비물 및 배설물 속 바이러스를 하수관로에서 신속하게 검출함으로써 특정지역의 감염성 질환 전파 정도와 유행하는 타입(변이)등을 분석하고 기존 역학조사의 문제점을 극복할 수 있으며 선제적인 대응이 가능하다. 현재 COVID-19의 대유행과 관련하여 WBE를 기반으로 한 다양한 연구가 진행되고 있으며 실제 환자의 발생과 상관관계가 있음이 확인되고 있고 백신 접종과 새롭게 발생한 변이바이러스의 관계 속에서 발생하는 변수를 고려한 모델이 없다는 점을 들어 새로운 감염병 확산 예측 모델에 대한 필요성 또한 커지고 있다. 본 연구에서는 병원에서부터 하수처리장까지의 하수관거와 하수처리장에서의 SARS-CoV-2 검출농도 및 거동을 파악하는 것을 목적으로 하고 있으며 COVID-19의 감염규모 확산에 관한 방법론에서 수학적모델 (Euler Method, RK4 Method, Gillespie Algorithm)과 딥러닝 기반의 Nowcasting model과 Fore casting model을 살펴보고자 한다.

This study examines garden activity and garden plant preferences for development of the garden activity program using community garden aimed for communication and integration for multicultural age. As a result, for members of multicultural society had high portion of floral arrangement and crafts, growing plants in both indoors and outdoors garden for their garden activities, and using plants for cooking, growing plants in both indoors and outdoors garden was of higher portion for native korean. In the garden plant preferences, members of multicultural society liked ornamental plants the best, due to the environmental correspondence between the plant's place of origin and their home country, while native koreans tend to prefer vegetables, reflecting the recent interest in pro-environment crops and rise in demand of urban farming, veranda gardening and weekend farming. In this study, the garden activity program for communication and integration categorized the value of garden activity into three categories; the value of respect for life, the value of consideration through caring, the value of plant ethics, based on the above preference results. The value of respect for life can be achieved by understanding the meaning of life, experiencing the will to live, and understanding the characteristics of plants and me. The value of consideration of caring comes from waiting and nurturing for living things that are different from me and adapting to the environment as a living The value of plant ethics can give us the insights for human relationships, by understanding and experiencing the natural ecosystem and plant co-existing in it. The eight-session garden activity program also went through validity verification process by experts on gardening and multiculture, and the effectiveness of the program was proved.

The purpose of this study was to set related variables for leadership measurement in the leader of a community organization as an effort to Community development constantly. Therefore, in this study, first, various theories on leadership were reviewed. Second, approaches and variable relationships were reviewed by leadership theory study. Third, leadership measurement variables were set based on Bass's Transformational theory, one of new trend theory, to measure the leadership of the community organization leader. As a follow up, clear and scientific analysis, through empirical analysis, based on the variables set in this study will be made to measure leadership of a community organization after creating investigation tools based on the variables set in this study A literature study was mainly used. 'Human Behavior' by Dr Han-geom Lee, 'Leadership Theory' by Eung-seop Shin, many other related books, articles of the Human Relation Organization Association, and theses and Bass's writings. Major findings of this study, through the literature study, were as follows. As conventional leadership theories, characteristics theory, behavior theory and situational leadership theory were proposed. First, characteristics theory searches the characteristics of an effective leader. It proposes that effective leaders and ineffective leaders have different characteristics, respectively. Therefore, it proposes to study the leader's characteristics. However, there is not a flexed definition for leader's characteristics. Scholars make different definition on leader's characteristics, and they are very subjective. Thus it cannot be a valid theory. Second, behavior theory describes how the leader behaves to his fellows. It studies leader's behavior focusing on what type and what combination is the most effective in all situations. However, it has weakness in that it focuses on a leader's behavior only, and ignores the situational features. Third, situational theory describes the relationship between leadership type and situation. It suggests that there is not a single leadership style that can suit all situations. It emphasizes the relationship between leadership type and situation. Although situational theory considers more variables than characteristics theory or behavior theory, it also sees situations as static and flxed. Although Fiedler's theory tried to comply with situations, he did not analyze interactions between a leader and his fellows.

This study investigated the correlation between eating behavior patterns, including eating-habits, food preferences, snack intake levels, and eating-out frequency and stress levels in high school students (males 174 and females 122) in Seoul. Analysis of eating-habits showed that eating-irregularity and eating-speed increased with elevated stress levels in both males and females under stress. The size of meals decreased in males, whereas it increased in females under getting stress (P<0.01). Preferences for sugar, hamburgers, and pizza also increased in both males and females under stress. Eating-out frequency decreased in males with a high stress level (P<0.01), whereas it increased in females. As for eating-out partners, males did not show any changes, whereas females preferred friends to family when under stress. Eating-out expenses also increased in both males and females, particularly in females with a high stress level (P<0.05). Males under increased stress showed effective stress reduction by increasing food intake, whereas females under increased stress showed less effective results. Consequently, high school students under high stress, particularly females, showed negative changes in eating behavior patterns, including irregular eating-habits, increased instant food and snack intakes, and increased frequency of eating-out. Therefore, development of appropriate programs for reducing stress and persistent nutrition education to promote good dietary behaviors are required.

We suggested industry-specific priorities of R&D investment with R&D investment elasticity to GDP calculated from the ripple effect of 28 large-sized industry R&D investment, using a Computable General Equilibrium(CGE) Model. Priority orders apply to only 12 industries, because 16 industries with less than 1% of total investment have been excluded. First, R&D investment elasticity to GDP says that priorities are ordered as Basic metal products, Chemicals, drugs and medicines, Food, beverages and tobacco products, Electronic and electrical equipment, Transportation equipment, Precision instruments, Electrictity, gas, steam and water supply, General machinery and equipment, Communications and broadcasting, Construction, Other services, and Real estate and business services. These priorities show the status quo of Korean industry structures well. The GDP growth rate to 2030 year reference equilibrium, which is an auxiliary index, says a similar priority to results from R&D investment elasticity to GDP. In the end, two criteria of priority order can be functioned as a good index for National Science and Technology Commission deciding what industry to invest and what budget to allocate.

과거 한국의 식품 오염원 중 법적인 규제 등을 통해 구체적인 통제가 이루어지지 못하고 있는 것이 축산물의 항생제로 알려져 항생제 오 남용으로 인한 내성균의 출현으로 비상이 걸렸던 적이 있었다. 요즘은 항생제를 지나치게 많이 사용해 가축이나 인체 내의 병원성 미생물들이 내성이 생겨 문제가 되고 있어 2011년 7월부터 가축용 사료에 항생제 첨가가 금지하게 된다. 한국은 항생제 내성률 1위로, 2000년 세계보건기구(WHO)에 따르면 대표적 항생제인 페니실린에 대한 폐렴구균의 내성률이 70%로 세계 1위이다. 어느 보고서에 따르면, 축산물 1톤을 생산하는 데 사용되는 항생제가 스웨덴이나 뉴질랜드, 덴마크 등 축산 선진국이 31~44g에 불과한데 비해 한국은 911g에 이른다. 투여 경로는 배합사료에 포함된 양이 54%, 농가의 임의 치료가 40%, 수의사 처방은 겨우 6% 순으로 나타났다. 그러나 OECD 회원국 중 수의사 처방 없이 항생제의 임의 투여를 허용하고 있는 나라는 한국뿐이다. 세계보건기구(WHO)에서는 가축사료에 항생제를 첨가하지 말 것을 권장하고 있으며, 유럽연합(EU)도 항생제는 반드시 수의사의 처방에 의해서만 사용토록 제한하고 있다. 최근 국립수의과학검역원에 의하면, 축산용 항생제 사용량이 2008년에 비해 18%, 2001년에 l해 무려 38%가 감소되었으며, 이중 닭은 20%, 소의 항생제 사용량은 36%가 감소하였다고 밝혔다. 사육 가축들의 항생제 오남용을 줄이기 위해서는 사료에 첨가하는 항생제나 성장호르몬, 비소 투여 등의 투여 대신에 미생물 생균사료나 녹차사료, 한약재사료 등의 천연면역물질을 함유한 사료를 먹여 스트레스를 덜 받고 면역력 증강에 좋은 사료를 먹여 키운 건강한 가축으로 생산한 육류는 맛도 특별히 좋다. 본 자료의 대부분은 금년부터 3년간 농촌진흥청 국립축산과학원과 중국청도농업대학과 "고품질 축산물생산을 위한 중약제를 이용한 질병방지체제 연구"라는 과제로 공동협력연구를 수행하게 됨에 따라 지난 11월 4일부터 10일까지 필자가 중국 청도농업대학을 방문하여 세미나시 발표한 자료임을 밝혀두며, 국내 수의학 연구에도 도움이 되고 저 소개한다.
