목 적 : A. baumannii는 원내 감염의 중요한 원인으로 다양한 감염증을 일으키고 있으며, 다양한 항생제에 대하여 내성을 가지고, 다약제 및 범약제 내성도 점차 증가하고 있어 그 중요성이 높아지고 있다. 이에 소아에서의 A. baumannii 감염 현황 및 내성 발생 현황을 알아보고자 연구를 시행하였다. 방 법: 2001년 1월 1일부터 2008년 12월 31일까지 세브란스 병원에 입원치료 하였던 19세 이하의 소아환자 중 A. baumannii가 동정된 환자 505명, 680례에 대하여 후향적 방법으로 조사하였다. 다약제 내성은 3가지 이상의 항생제 그룹에 대하여 내성을 나타내거나 carbapenem에 대하여 내성을 나타내는 경우로 정의하였고, 범약제 내성은 세브란스 병원에서 항생제 감수성을 검사하는 모든 항생제에 내성을 나타낼 경우로 정의 하였다. A. baumannii의 감염빈도 및 항생제 내성 발생 현황의 연도별 추이에 대하여 조사하였으며, 재원장소, 항생제 사용 유무, 기계 호흡유무 등에 따른 감염빈도 및 다약제, 범약제 내성 발생의 차이에 대하여 조사하였고, 이에 대해 카이제곱 검정, t-검정을 사용하여 통계적 유의성 여부를 알아보았다. 결 과 : A. baumannii 가 동정된 환자들의 기저질환은 혈액종양성 질환, 신경계 질환이 각각 208례(30.6%), 165례(24.3%)로 가장 많았으며, 만성소모성 질환이 많았다. 객담과 소변검체에서 많이 동정되었다. A. baumanii의 검출 빈도는 항생제를 사용하였던 환자들에서 78.1%로, 사용하지 않은 그룹에 비하여 더 높았다. 다약제 내성 및 범약제 내성 A. baumannii의 발생빈도는 중 환자실 재원의 경우 각각 76.4%, 38.3%였고, 기계호흡을 하였던 경우 76.8%와 38.9%로 일반병실 재원 환자 및 기계호흡을 하지 않았던 환자보다 더 높은 빈도를 보였다. 연도별 발생추이는 2001년부터 2004년까지 증가 하다가 2005년 대폭 감소하였으며 이후 다시 증가하여 2008년에는 다약제 내성균주가 63.5%, 범약제 내성균주가 48.2%에 이르렀다. 항생제 내성균의 증가는 모든계열의 항생제에서 나타나고 있으며 2008년에는 모든계열의 항생제가 50% 이상의 내성률을 나타내었다. 항생제 내성은 중환자실 재원여부, 항생제 사용 및 기계호흡 여부와 상관하여 증가하였다(P <0.0001). 결 론:소아에서의 다약제내성, 범약제내성 A. baumannii의 증가는 항생제 과다사용 및 내성 균주의 전파 때문으로 생각되며, 철저한 환경관리가 A. baumannii 감염으로의 이환 및 내성 균주 발생 방지에 중요한 역할을 함을 알 수 있었다.

성층권의 오존층 파괴로 수반되는 부작용에는 우주의 자외선이 차단되지 않고 지구표면에까지 도달하는 것을 들 수 있다. 이로 인하여 생태계 파괴를 비롯하여 기후이상 및 인체 건강장애 발생의 가능성이 높아진다고 알려져 있다. 특히 자외선 노출로 인한 피부암 발생에 관한 여러 연구결과가 보고 되었으며 이에 대한 종합적이고 신뢰성 있는 재평가 필요성이 대두되었으며 유사한 연구의 국내 수행이 제시되는 때이다. 이에 메타분석이라는 방법을 통하여 신뢰성있는 BAF 값을 추정하여 보고 이 지수를 국내 자료에 적용하여 국내 피부암 발생의 변화 양상을 자외선 증가와 함께 추정하여 보았다. 3개국의 자료를 일원화하여 추정된 UVB 계수는 지수함수 모델에 의해서는 $2.07\times10^{-6}$으로, 멱함수 모델에 의해서는 2.49로 산출되었으며, 이들 모두 통계적으로 유의한 것으로 나타났으며, 이 계수로부터 BAF 값을 추정한 결과, 서울 일부 지역에서의 UVB 조사량이 1% 증가되면, 피부암 발생률은 지수함수 모델에서는 1.90%, 멱함수 모델에서는 2.51%가 증가되는 것으로 산출되었으며, 이 연구에서 적용한 메타분석의 방법으로 제시된 위해도는 비교적 신뢰도가 높을 것으로 추정된다. 현재 우리나라에서의 비흑색종 피부암 발생율이 백만명당 11명이라고 가정할 때, UVB 조사량이 1% 증가됨으로 인해 국내 비흑색종 피부암 발생율은 백만명당 11.1명$\sim$11.3명으로 증가되는 것으로 예측된다. 이렇게 낮은 수준의 위해도에도 불구하고 자외선 노출이 피부암 발생의 원인적 요인이라는 것이 밝혀진 지금, 이에 대한 불필요한 노출을 가능한 삼가고 계속적인 관심을 두어야 할 것이다.

본 연구는 EMT-6 세포를 이용하여 무기수은, 유기수은 및 카드뮴의 세포독성에 대한 glutathione(GSH)의 방어효과를 알아보고자 하였다. 무기수은, 유기수은 및 카드뮴을 첨가한 배양조건에서 EMT-6 세포의 세포생존율, ${NO_2}^-$ 및 ATP 생성량은 첨가한 중금속의 농도가 증가할수록 용량의존적으로 감소하였다. GSH, OTC 및 BSO를 단독 첨가한 배양조건은 세포의 세포생존율과 NO2- 및 ${NO_2}^-$ 생성량에 영향을 주지 않았다. 수은화합물 및 카드뮴과 GSH를 동시 첨가한 배양조건에서는 세포생존율이 90% 이상 유지되었고, ${NO_2}^-$ 및 ATP 생성량은 기본배양조건과 비슷한 수준으로 나타났다. $16{\mu}M$의 무기 및 유기수은과 $160{\mu}M$의 카드뮴을 첨가한 실험조건에 GSH를 동시 첨가했을 경우 방어효과는 GSH의 농도에 따라 용량의존적으로 증가하였다. 세포내에서 수은 및 카드뮴의 세포독성에 대한 GSH역할을 알아보고자 GSH, OTC, BSO 전처리 실험을 한 결과, GSH의 전처리는 이들이 세포막을 통과하지 못하기 때문에 대조군과 비슷한 양상으로 나타난 반면에 BSO를 전처리한 군에서는 세포내 GSH 농도의 감소로 수은의 세포 독성이 증가하여 대조군에 비하여 ${NO_2}^-$와 ATP 생성량이 현저히 감소하였다. 또한 세포내 GSH의 농도를 증가시키는 OTC를 전처리한 결과 수은의 독성에 대한 방어효과가 시간 및 용량 의존적으로 현저하게 증가하였다. 이러한 실험결과는 수은의 세포독성에 대한 GSH의 방어효과가 GSH 세포내 농도와 밀접한 관련이 있음을 간접적으로 보여주고 있다. 본 연구의 결과는 수은 및 카드뮴의 독성에 대한 GSH의 방어작용이 단순히 -SH기와 중금속의 결합에 의한 결과가 아니라 세포내에서 GSH 분자가 갖는 고유의 기능으로 판단되며, 특히 중금속에 의한 에너지대사의 장애를 GSH가 회복시킬 수 있음을 보여준다.

This investigation grasps the level and relevant elements of performance of health promotional activities for the elderly in Korea. It provides fundamental data on health promoting projects targeting the elderly population from farming villages. Hence, this study gropes for an effective approach and measures of health promoting programs. The program needs to be developed with a focus on elderly people from farming villages. In addition, it was carried out in order to provide basic data for development of health projects for local communities. Data gathering was based on survey data targeting patients from the free clinic service. Service was rendered for the residents of farming villages, and conducted at the Offices of CheonBuk Province from October 2000 to December 2000. Analytical results were used to examine the health promotional method for the elderly in the aspect of Oriental Medicine. SPSS 9.0 version as well as T-test and ANOVA were used for survey data analysis. Piersons correlation coefficient was utilized for the relationship for each area, obtaining the following analytical results. 1. The average score for the activities of health promotion was 2.28. Looking at each subcategory, stress management was the highest at 3.65; interpersonal relationship, 3.00; nutrition, 2.55; health responsibility, 2.15; self-realization, 2.03; and exercise was the lowest at 1.89. 2. With respect to lifestyle of the health promotion secondary to general features of elderly people from farming villages, the level of activities of health promoting lifestyle was shown to be higher for males than that of females. Self-realization area was high among males in detailed particulars while the level of execution was high as age decreases in the stress area. 3. Regarding health promoting life style secondary to socioeconomic characteristics, the level of execution was higher for the individuals with a higher level of education and further utilization of spare time. With respect to occupation, the level was highest for people from the fishery. The level decreased in the order of other occupations such as trade, unemployed and agriculture, which was shown to be the lowest. In detailed particulars, it revealed that higher the individuals educational level, the higher the self-realization and stress management areas. The level of interpersonal relationship was the highest among people with little or no education. With respect to self-realization area, the level was highest among the cases where one paid living expenses along with their children. The lowest level of living expenses was seen in the cases where an individual pays for living expenses by himself/herself. There were significant results in all areas except for nutrition areas depending on occupation. The fishery was shown to be the highest. The level of activities was higher as one utilizes more spare time in all areas except for the area of interpersonal relationship.

The current industrial health service is shifting to health improvement business with 1st primary prevention-focused service from secondary and tertiary prevention-focused business, and Oriental medicine can provide such primary prevention-focused service due to the characteristics of its science. In particular, the advanced concept of health improvement can match the science of health care of Oriental medicine. Notably, what is most important in health improvement is our lifestyle, This does not underestimate the socio-environmental factors, which have lessened their importance due to modernism. The approach of Oriental medicine weighs more individuals' lifestyle and health care through self-cultivation. This matches the new model of advanced health business. Oriental medicine is less systemized than Western medicine, but it can provide ample contents that enhance health. If we conceive health-improvement program based on the advantages provided by these two medical systems, this will influence workers to the benefit of their health. Also, health Program needs to define factors that determine individual lives, and to provide information and technologies essential to our lives. The Oriental medicine approach puts more stress on a subject's capabilities than it does on the effect his surrounding environment can have. This needs to be supported theoretically by not only defining the relations between an individual's health state and his lifestyle, but also identifying the degree to which an individual in the industrial work place practices health improvement lifestyle . This is the first step toward initiating health-improvement business . In order to do this, this researcher conducted a survey by taking random samplings from workers, and can draw the following conclusions from it. 1 The sampled group is categorized into', by sender, female 6.6%, and male 93.4%, with males dominant; by marriage status , unmarried 43.9% and married 55.6%, with both similar percentage, and, by age, below 30, 48.4%, between 30 and 39, 27.4%, between 40 and 49, 18.2%, and over 50, 6.0%. The group further is categorized into; by education, middle school or under 1.7%, high school 30.5%, and junior college or higher 65.8% with high school and higher dominant: and by income, below 1.7 million won 24.2%, below 2.4 million won 14.8%, and above 2.4 million 6.3% Still, the group by job is categorized into collegians with 23.9%, office worker with 10.3%, and professionals with 65.8% , and this group does not include workers engaged in production that are needed for this research, but mostly office workers . 2. The subjects selected for this survey show their degree of practicing health-improvement lifestyle at an average of 2.63, health management pattern at 2.64, and health-related awareness at 2.62 The sub-divisions of health-improvement lifestyle show social emotion (2.87), food (2.66). favorite food (2.59), and leisure activities (2.52), in this order for higher points. It further shows health awareness (2.47) and safety awareness (2.40), lower points than those in health management pattern . 3. In the area of using leisure time for health-improvement, males, older people, married, and people with higher income earn higher marks. And, in the area of food management, the older and married earn higher marks . In the area of favorite food management, females, lower-income bracket, and lower-educated show higher degree of practice , while in the area of social emotion management, the older. married, and higher-income bracket show higher marks. In addition, in the area of health awareness, the older, married, and people with higher-income show higher degree of practice. 4. To look at correlation by overall and divisional health-improvement practice degree , this researcher has analyzed the data using Person's correlation coefficient. The lifestyle shows significant correlation with its six sub-divisions, and use of leisure time, food, and health awareness all show significant correlation with their sub-divisions. And. the social emotion and safety awareness show significant correlation with all sub-divisions except favorite food management.

The purpose of this study was based on students in high school to find out how interest eating and controlling weight on normal time by sex to let them get a better sense's of view on weight controlling so they can get healthy, and healthy school life and concentrate on studying, As a result of analyzing the data collected for the subject of high school students, the conclusions were as follows; First, out of 325 students, 44.6% were male students, and 179 were female students, Compared to the BMI, normal mass were 50.8%, which were 165 students, less weighted were 39.7%, which were 129 students, and over weighted were 9.5%, which were 31 student. Also average height for male students were 173.8 cm, for female students were 161.5 cm, average weight were 67.2 kg for male students, and for female students were 53.2kg. Using BMI analysing the results and the male students had an average of 22.2%, and the female students had an average of 20.3%, so male students were a little higher than the female students. Second, the interest rate for weight control were 82.2%, that's 267 students for, 'interested' and 7.8%, which were 58 student for 'not interested', so most students were interested, in controlling weight. Interest rate were 83.6% for male students, 81.0% were female students. BMI told that group of less weighted were 82.9%, group of normal were 79.4% and group of over weighted were 93.5%. The rate were all high not relating to BMI. Third, compared to the past, more people said 'normal'(41.3%), people who said 'a little fat'(36.3%) decreased, but they still think they are fat even though they are not, also when they are less weighted they still think they are fat. Fourth, for 'weight control, and food' both male and female said they were related, and for 'weight control and exercising' they also said they were related, but more male said that they were related, However for relations between' controlling weight and school's physical education class' the answers were usually disagree. Fifth, for the 'satisfaction of their present weight', both BMI and the students answered and this results were mostly same as the past result, so most students prefer to lose weight. Also, both male and female think that the reason they have this weight now is, because of 'the amount of exercises' and 'the amount of food they eat', so they find that it's related to each other. Sixth, for the experience on weight control, both male and female had experiences, and they answered 'exercising and food treatment' is the good way to control weight. Also for 'the reason they started to control there weight', both male and female answered, 'they thought there weight were not normal'. Seventh, 'Do you pick on food to control weight?' and 'Do you feel nervous before you eat?' and for last 'control of drinking water' the answer was all different, and both male and female answered negatively. Eighth, time wasted on exercising per day, for less than 30 minute were 81.5%, the form of exercises that students did were 'not much or walking on the way to school and way to home'. Usually for their free time, male students spend on exercising however female student did not. Also both female and male students showed that they like to exercise, but majority of female student disliked to exercise. To everyone's point of view 'like'(32.9%), 'like a lot'(20.9%), so everyone agrees. The knowledge information on controlling weight, they answered, usually found from commercials, newspaper or magazines and from parents or friend. From the past many high school students wanted to control their weight, so there should had been a good education on this, however there wasn't any of those education and still it doesn't exist. Also most school's education are arranged to entrance pressure so they have a lot of knowledge and informations to it, but for real they don't have any activity or actions on it. Through this research, we felt that, we should correct students with wrong understanding on controlling weight and wrong knowledge. Also we suggest to make an activity program for this.

This study is designed to analyze the problems of health education in schools and explore the ways of enhancing health education from a historical perspective. It also shed light on the managerial aspect of health education (including medical-check-up for students disease management. school feeding and the health education law and its organization) as well as its educational aspect (including curriculum, teaching & learning, and wishes of teachers). At the same time it attempted to present the ways of resolving the problems in health education as identified her. Its major findings are as follows; I. Colculsion and Summary 1. Despite the importance of health education, the area remains relatively undeveloped. Students spend a greater part of their time in schools. Hence the government should develop a keener awareness of the importance of health education and invest more in it to ensure a healthy, comfortable life for students. 2. At the moment the outcomes of medical-check-up for students, which constitutes the mainstay of health education, are used only as statistical data to report to the relevant authorities. Needless to say they should be used to help improve the wellbeing of students. Specifically, nurse-teachers and home-room teachers should share the outcomes of medical-check-up to help the students wit shortcomings in growth or development or other physical handicaps more clearly recognize their problems and correct them if possible. 3. In the area of disease management, 62.6, 30.3 and 23.0 percent of primary, middle, and highschool students, respectively, were found to suffer from dental ailments. By contrast 2.2, 7.8, and 11.5 percent of primary, middle and highschool students suffered from visual disorders. The incidence of dental ailments decreases while that of visual impairments increases as students grow up. This signifies that students are under tremendous physical strain in their efforts to be admitted by schools of higher grade. Accordingly the relevant authorities should revise the current admission system as well as improve lighting system in classrooms. 4. Budget restraints have often been cited as a major bottleneck to the expansion of school feeding. Nevertheless it should be extended at least, to all primary schools even at the expense of parents to ensure the sound growth of children by improving their diet. 5. The existing health education law should be revised in such a way as to better meet the needs of schools. Also the manpower for health education should be strengthened. 6. Proper curriculum is essential to the effective implementation of health education. Hence it is necessary to remove those parts in the current health education curriculum that overlaps with other subjects. It is also necessary to make health education a compulsory course in teachers' college at the same time the teachers in charge of health education should be given an in-service training. 7. Currently health education is being taught as part of physical education, science, home economics or other courses. However these subjects tend to be overshadowed by English, mathematics, and other subjects which carry heavier weight in admission test. It is necessary among other things, to develop an educational plan specifying the course hours and teaching materials. 8. Health education is carried out by nurse-teachers or home-room teachers. In connection with health education, they expressed the hope that health education will be normalized with newly-developed teaching material, expanded opportunity for in-service training and increased budget, facilities and supply of manpower. These are the mainpoints that the decision-makers should take into account in the formation of future policy for health education. II. Recommendations for the Improvement of Health Education 1. Regular medical check-up for students, which now is the mainstay of health education, should be used as educational data in an appropriate manner. For instance the records of medical check-up could be transferred between schools. 2. School feeding should be expanded at least in primary schools at the expense of the government or even parents. It will help improve the physical wellbeing of youths and the diet for the people. 3. At the moment the health education law is only nominal. Hence the law should be revised in such a way as to ensure the physical wellbeing of students and faculty. 4. Health education should be made a compulsory course in teachers' college. Also the teachers in service should be offered training in health education. 5. The curriculum of health education should be revised. Also the course hours should be extended or readjusted to better meet the needs of students. 6. In the meantime the course hours should be strictly observed, while educational materials should be revised in no time. 7. The government should expand its investment in facilities, budget and personnel for health education in schools at all levels.

To investigate the actual conditions of smoking in middle and high school students in Chinan County, I used a sturctured questionnaire for 1,579 students attending twelve middle-high schools from December 1, 1998 to December 20, 1998. I collected and data correlated the using an $SPSS-PC^+$ 1. The smoking rate of middle-high schoo1 students in Chinan County was 17.9%, relatively high. This smoking rate was different according to the gender, grade, religion, and economic situation. In mals, high school students, non-religious, students low income family students, the smoking rate was higher. The smoking rate of high school students was almost the same as the smoking rate of adults, generally higher than that of foreign teenagers. Because the smoking rat of studinets in the third grade of middle school and in the first grade of high School was six times higher, increased education should be conducted during this time in an attempt to curb the sudden increase of the smoking rate. The smoking rate of girl students was 5.0%; this has increased mor than three times from ten years ago. Consequently, counter measures should be taken against the smoking of female students as well as juvenile smoking in general. In addition, the smoking rate of middle-high school students showed interesting differences when correnated with enviornmental factors. Students with low grades, who are not satisfied with school life, who don't have both parents, who have uncaring parents who nare too strict or too arbitary, who have smoking parents, or who have experienced smoking commonly smoked. Therefore, to lower the smoking rate we should improve the school environment, improve a student's interest in school life. And parents or siblings should lead by example and quit smoking at home. Schools should educate students more effectively concerning the harmful effects of smoking and create an accurate understanding of its dancers. From the beginning, we should teach students never ever to touch cigaretts. 2. The surve discovered that most students started out of curiosity, or solicitantion from friends or elders at middle school, and had been smoking one to five cigarettes for more than a year. They obtained cigarettes at stores and most of them have friends who smoke. As a result anti-smoking education should be conducted at elementary schools prior to middle school. More than 95% of the teenagers who smoke had friends who smote and smoked out of curiosity or the recommendation of elders. Thus, we must focus on teenagers who smoke in group, rather than individually. Fuyrthermore, the strict application of the regulation of tobacco sales as well as tobacco cooperation from retailers are needed. While students did not show any mood or academic achievement difference after beginning smoking, 58.1% of the students a health situdation that was worse. Juvenile smoking is more harmful to the juvenile than adult smoking is to the adult. This should be focused on in an anti-smoking campaign. 3. Students who smoke hada more positive attitude toward smoking than students who don't smoke. Students who smoke had a tendency to have a nuetral position and are not concerned about smoking compared to non-smoking students. The survey showed that the great number of students had a nuetral position. Because this nuetrality may increase Juvenile smoking, education that provides an exact understanding of smoking should be performed to build the correct attidude toward smoking. 4. Middle school students smoke when angry, gloomy, anxious, a lone and when they have some problems to solve, on when they feel inconveniened in other wores, they smoke to reliver stress. They also smok due to addiction. Because smoking is not a praetical method to relieve stress, a program which helps to acquire positive relief stress should be provided to help reduce smoking. 5. About 65% of students who smoke want to quit smoking because of health problem, 78% of them have tried mor than once to quit but failed due to weak will power and peer pressure from friends who smoke. Juvenile smoking is group, oriented. Thus, the program that advances less smoking will be the one that focuseds on groups. 6. As for advice to students who want to quit smoking, "persuasion" was used most commonly, followed by a "presentation on how to quit smoking". Another method were severe punishment. About 70% of the students wanted the anti-smoking guide at school. 7. Most students (73.5%) had a position that more anti-smoking education at school is needed. Obriously, then, anti-smoking education at middle-high schools should be reinfoced. Although the education which explains the harmful influence of tobacco is known as an efficient way prevent smoking; it does not influence students who already smoke. Therefore, for students who smoke, multi-dimensional approaches must be attempted that include physical training, phychokogical approache, consultation and discussion, medical chek-ups, audio-visual education technigues, and professonal instructors, in addition, because smoking students have more negative on lukewarm attitude to anti-smoking education anti-smoking education should be conducted through a communicative style by dedicated teachers who care about students. In order to increase the effectiveness of this program.

배수조건이 다른 평야지 논토양에서 돈분뇨액비를 시용한 후 벼 생육 및 양분의 이동양상을 구명하여 농경지에서 돈분뇨 액비 재활용을 위한 기초 자료를 얻고자 배수조건이 약간양호 및 약간불량논에서 질소 성분함량이 0.53%인 돈분뇨액비를 LPM-100%는 $20.8Mg\;ha^{-1}$ (N 110 kg 표준시비량 해당), LPM-150%는 $31.1Mg\;ha^{-1}$ (N 165 kg 해당), LPM- 200%는 $41.5Mg\;ha^{-1}$ (N 220 kg 해당)을 각각 살포하여 시험한 결과는 다음과 같다. 벼 생육 및 수량은 LPM-N150 이상 시용에서 화학 비료를 처리한 대조구와 비슷하였고, 배수약간양호토양에서 약간불량토양보다 수량이 3-11% 증수되었으나 벼의 절간장이 길어져 도복의 위험성이 증가되었다. 돈분뇨액비 시용시 $NH_3$ 휘산량은 액비시용초기와 액비시용량이 증가될수록 많았고 액비시용 후 로타리 경운은 무로타리보다 LPM-N100%, LPM-N200% 시용에서 $NH_3$ 가스 누적량이 각각 59%, 25% 감소되었다. 강우시 액비 시용담 표면유거수중 무기성분 유실량은 액비 시용량이 많을수록 증가되었고 LPM-N150% 이상 시용에서 $NO_3-N$, $NH_4-N$, $SO_4$, Ca, K 성분 등이 많이 유실되었다. 한편 지하침투수중 $NO_3-N$, K유실량이 LPM-N150% 이상 시용에서 대조구보다 많았고, 배수약간양호토양이 약간불량토양보다 $NO_3-N$, K용탈이 많았다. 액비시용토양 중 질소형태 변화는 $NO_3-N$는 이앙 30일전(비담수기)인 액비 시용 초기부터 25일까지 점점 높아지다가 담수기에는 낮아졌고, $NH_4-N$는 액비시용초기부터 담수기인 액비 시용 후 25일에서 65일까지 높게 유지되다가 낮아졌으며, 토양 중 인산과 칼리 함량은 LPM-N100% 이상 시용에서 시험전보다 증가되었다. 결론적으로 돈분뇨액비 시용은 벼 생육과 수량을 고려하면서 환경부하를 최소화하는 방향으로 활용되어야 한다고 판단된다.
