UNESCO and IUCN established the term of 'Sacred Natural Sites' (areas of land or water having special spiritual significance to peoples and communities) for conservation of biological and cultural diversity. Dangsan forest, a traditional village forests of rural Korea is a representative 'Sacred Natural Site' with a history of more than several hundred years of Dangsan ritual. The Chungmak village, Gyeokpo-ri, Buan-gun is a small seashore village. It is an important place that has the largest ancient maritime ritual sites in Korea. Buan-gun have been tried to register the 'Chungmak-dong Ritual Site' for the World Heritage List. However, the fact that this 'Chungmak-dong Ritual Site'(5~6 century, Baekje of the Three-kingdom period) was located in the Dangsan forest, surrounding the shrine, is not much understood. In this study, the landscape characteristics and culture of the sacred Dangsan forest at Gyeokpo-ri, including Gyeokpo-ri, Dae-ri, Naesosa temple Seokpo-ri, Buan-gun and Dongho-ri, Gochang-gun were investigated. And, the potential of registering for World Heritage, 'Protected Area of Sacred Natural Sites' by linking the four site's Dangsan forests has been investigated. The sacred Dangsan forests in the neighborhood of Gyeokpo-ri have kept their landscape characteristics and retained Dangsan ritual. As a result of SWOT analysis for sacred natural sites, WT(weakness-threat) strategy has chosen as priority strategy. The reason is that there is few management scheme. The Dangsan forests at the neighborhood of Gyeokpo-ri need to be recognized by people in Korea, for their valuable landscape characteristics. The places should be managed and protected to remain as a sacred natural sites in order to be prepared for a World Heritage.

The purpose of this study was to identify the knowledge contents of basic nursing sciences needed by nurses in the practices of the intensive care unit(ICU). To attain the goal of this study, the nurses working at 10 hospitals in the areas of Seoul and Kangwon Province were randomly selected. They were primarily interviewed, and the open question was secondarily put to them through the questionnaire. In the process of the 1st interview, the interviewees were asked of the question, "What is the knowledge of basic sciences such as anatomy, pathology, physiology. microbiology, pharmacology and the like thought to be lacking when you communicate with doctors in the ICU and when you carry out your nursing practices in it?" The contents of the interview were tape-recorded. The period of data collection ranged from May 1, 2001 to Sept 30. The interviews were conducted with total of 20 nurses. The open-end questionnaire was secondarily mailed to nurses. 113 questionnaires were returned. 100 questionnaires except 13 ones thought to be poorly completed in content were used for data analysis. Three coders classified data obtained from the interview and the questionnaire research into 5 detailed items relating to such as anatomical physiology, pathology, pharmacology. microbiology and basics of nursing. The three coders had experiences in nursing education of 18 years, 8 years and 6 years, respectively, and of them one coder was professor in basic nursing sciences. Data were statistically treated using frequency analysis and percentage by the SAS program. As a result, the following findings were obtained : It was found that the contents that ICU nurses responded were most needed in the field of Human structure and function were water and electrolytic balance(38%), blood and circulatory system(20%), changer in the patient's skin(12%), the arrangement of the human body(10%) and the endocrine system(10%), nervous system(6%), and assessment of the state of the patient's consciousness(4%). It was found that the contents that ICU nurses responded were most needed in the field of pathology were found to be the process of the progress of the disease(32%), symptoms of the disease(27%), prognosis of the disease(22%), followed by the injury-healing process, clinical pathological examination, and examination by radiation. It was found that the contents that nurses responded were most needed in the field of pharmacology were the effect of drug(25%), the side effect of drug(22%), the relationship between diseases and drug(20%), the relationship between disease-causing bacteria and drug(20%) and chemotherapy(2%). It was found that the contents that ICU nurses responded were most needed in the field of microbiology were the relationship between diseases and disease-causing bacteria(45%), Kinds and characteristics of disease-causing bacteria(18%), infection control(16%), application of the aseptic technique(12%), isolation(9%) and the like. It was found that the basic knowledge that ICU nurses responded were needed were the identification of the patient's current state(36%), understanding of the therapeutic process(22%), the operating principle of medical equipment and instrument(20%), medical terminology(9%), equipment and instrument management(7%), calculation of the dose of injection(2%) and the like.

This research intends to survey family environment, health behavior and health status of the students in urban-rural elementary schools and analyze those factors comparatively, and use the result as basic material for school health teacher to teach health education in connection with family and regional areas. It also intends to improve a pupil's self-abilitiy in health care. The subjects involve 2,774 students of urban elementary schools and 583 student in rural ones, who were selected by means of a multi -stage probability sampling. Using the questionnaire and school documents, we collected data on family environment, health behavior and health status for 19 days. Feb. 2nd 1998 through Feb. 20th 1998. The R -form of Family Environment Scale (Moos, 1974) was used in the analysis of family environment(Cronbach's Alpha =0.80). Questionnaires of Health Behavior in School-aged children used by the WHO in Europe(Aaro et al., 1986) and the ones developed by the Health Promotion Committee of the Western Pacific(WHO, 1995)(adapted by long Young-suk and Moon Young-hee(1996)) were used in the analysis of health behavior, as well documents on absences due to sickness, school health room-visits, levels of physical strength, height, weight and degree of obesity were used to determine health status. In next step, We used them with an $X^2$-test, t-test, Odds Ratio, and a 95% Confidence Interval. 1. In two dimensions of three, family-relationship (t=3.41, p=0.001) and system -maintenances(t= 2.41, p=0.0l6) the mean score of urban children were significantly higher than those of rural ones. In the personal development dimension however, there was little significant difference. Assorting family environment into 10 sub-fields and analyzing them, we recognized that urban children were superior to rural children in the sub-fields of expressiveness (t =3.47, p=0.001), conflict (t=0.48, p=0.001), active-recreational orientation (t = 1.97, p=0.049) and organization (t=4.33, p=0.000). 2. Referring to the Odds Ratios of urban-rural children's health behaviors, urban children set up more desirable behavior than rural children wear ing safety belts (Odds Ratio =0.32, p=0.000), washing hands after meals(Odds Ratio = 0.43, p= 0.000), washing hands after excreting (Odds Ratio = 0.39, p=O.OOO), washing hands after coming - home ( Odds Ratio = 0.75, p = 0.003), brushing teeth before sleeping(Odds Ratio =0.45, p=0.000), brushing teeth more than once a day (Odds Ratio =0.73, p=0.0l2), drinking boiled water (Odds Ratio = 0.49, p=0.000), collecting garbage at home(Odds Ratio=0.31, p=0.000) and in the school(Odds Ratio =0. 67, p=0.000). All these led to significant differences. As to taking milk(Odds Ratio = 1.50, p=0.000), taking care of eyesight(Odds Ratio=1.41, p=0.001) and getting physical exercise in(Odds Ratio = 1.33, p=0.0l9) and outside the school(Odds Ratio = 1.32, p=0.005), rural children had more desirable behavior which also revealed a significant difference. There was little significant difference in smoking, but the smoking rate of rural children(5.5%) was larger than that of urban children(3.9%). 3. Health status was analyzed in terms of absences, school health room-visits, levels of physical strength, and the degree of obesity, height and weight. Considering Odds Ratios of the health status of urban-rural children, the health status of rural children was significantly better than that of the urban ones in the level of physical strength(t=1.51, p=0.000) and the degree of obesity(t=1.84, p=0.000). The mean height of urban children ($150.4{\pm}7.5cm$) is taller than that of their counterparts($149.5{\pm}7.9$), which revealed a significant difference (t =2.47, p=0.0l4). The mean weight of urban children($42.9{\pm}8.6kg$) is larger than that of their counterparts($41.8{\pm}9.0kg$), which was also a significant difference(t=2.81, p=0.005). Considering the results above, we can recognize that there are significant differences in family environment, health behavior, and health status in urban-rural children. These results also suggestion ideas for health education. What we would suggest for the health program of elementary schools is that school health teachers should play an active role in promoting the need and importance of health education, develop the appropriate programs which correspond to the regional characteristics, and incorporate them into schools to improve children's ability to manage their own health management.

The objective of this study was to explore hygiene issues by analyzing the importance and performance of personal and school hygiene in school foodservices. Questionnaires were administered to 634 students (10 high schools) in the Busan area. Exactly 29% of respondents had received hygiene education. The average score of importance of students' personal foodservice hygiene was 3.81/5.00, and the performance score was 3.48/5.00. The same scores for school foodservice hygiene were 4.37/5.00 and 3.67/5.00, respectively. Regarding importance and performance of personal foodservice hygiene, students who had received hygiene education showed significantly (P<0.01) higher scores than those without prior education. In terms of importance of school foodservice hygiene, students who had received hygiene education showed significantly higher scores for environment hygiene (P<0.05) and equipment hygiene (P<0.05). Additionally, among grid analysis in personal foodservice hygiene, the areas of high importance and low performance included 'washing hands before the meal', 'using a designated cup for the water purifier', and 'keeping clean around the leftover container'. As for school foodservice hygiene, the same area was 'cleanliness of tray'. These findings suggest that hygiene education needs to be extended to more students, and for school foodservice hygiene, a cleaner environment should be created using equipment hygiene management, including emphasis on ensuring cleanliness of tray.

The purpose of this study was to obtain baseline data on nutritional management of women's bone health. We examined the bone mineral density (BMD) by ultrasound bone densitometer, anthropometric measurement and dietary intake to assess the nutrient intakes. The subjects were 102 Korean female college students (normal=59, bone disease group [osteopenia+osteoporosis]=43) and the mean age was 21.4 yr. Mean T-score (BMD) were -0.42 and -1.52 in normal and bone disease groups, respectively. Anthropometric measurement showed that 59% of the subjects were normal weight and bone disease group had lower value than normal group in majority of anthropometric index. The average energy intake was 1539.7 kcal, which was 73% of Korean EER. The subjects had lower vitamin C, folic acid, Ca and K intake than Korean RI independent of BMD. Bone disease group (1:2.05) showed significantly lower Ca:P ratio than normal group (1:1.86). Normal group had more intake frequency of milk and milk product than bone disease group. In relation to anthropometric index with T-score, significant correlations have been found in weight, PM, BFM, MM, TBW, SLM, FFM WHR, BMI and SMM. In relation to dietary factors with T-score, significant correlations have been found relating to intake frequency of milk and milk product. Our results indicate that for nutrients, ratio and balance may be more influential than intake for bone health in young women.

The amount of swine wastewater reaches about $197,000m^3$ per day at live-stock houses in the whole country. A half of the swine wastewater resources are too small to be restricted legally. This untreated wastewater causes the eutrophication in the water bodies. In case of swine wastewater treatment, the solid-liquid separation must be performed because feces(solid phase) and urine(liquid phase) have large differences in nitrogen and phosphorus concentration. It is necessary to assess exactly the concentration of the pollutants in swine wastewater for planning the wastewater treatment facilities. A full-scale operation was carried out in K city and the plant is consists of conventional plant, the supplementary flocculation basin of chemical treatment process and $anaerobic{\cdot}aerobic$ basin for nitrogen removal. The improved full-scale swine wastewater treatment plant removed the $1,500{\sim}3,000mg/l$ of total-nitrogen(T-N) to 120mg/l of T-N and $131{\sim}156mg/l$ of total-phosphorus(T-P) to $0.15{\sim}1.00mg/l$ of T-N. Accordingly, as a results of operational improvement, the removal efficiencies of T-N and T-P were over $92{\sim}96%$, 99%, respectively. The continuous supply of organic carbon sources and the state of pH played important roles for the harmonious metabolism in anaerobic basin and the pH value of anaerobic basin maintained at about 9.0 for the period of the study.

BACKGROUND: Accurate estimates of total direct $CH_4$ emissions from croplands on a country scale are important for global budgets of anthropogenic sources of $CH_4$ emissions and for the development of effective mitigation strategies. Methane production resulted by the anaerobic decomposition of organic compounds where $CO_2$ acts as inorganic electron acceptor. This process could be affected by the addition of rice straw, water management and rice variety itself. METHODS AND RESULTS: Rice (Oryza sativa L. Japonica type, var Samkwangbyeo) was cultivated in four plots: (1) Nitrogen-Phosphorus-Potassium (NPK) ($N-P_2O_5-K_2O$:90-45-57 kg/ha); (2) NPK plus 3 Mg/ha rice straw (RS3); (3) NPK plus 5 Mg/ha rice straw (RS5); (4) NPK plus 7 Mg/ha rice straw (RS7) for 3 years (2010-2012) and the rice straw incorporated in fall (Nov.) in Gyeonggi-do Hwaseong-si. Gas samples were collected using the closed static chamber which were installed in each treated plot of $152.9m^2$. According to application of 3, 5, 7 Mg/ha of rice straw, methane emission increased by 46, 101, 190%, respectively, compared to that of the NPK plot. CONCLUSION(S): We obtained a quantitative relationship between $CH_4$ emission and the amount of rice straw applied from rice fields which could be described by polynomial regression of order 2. The emission scaling factor estimated by the relationship were in the range of IPCC GPG (2000).

This trial was conducted to investigate effects of different feeding types of conventional or total mixed rations (TMR) provision on feed intake, nutrient digestibility, nitrogen retention and blood metabolite characteristics in different breeds of native and cross bred Korean black goats. Ten Korean native male goats and 10 Korean crossbred black male goats (Korean native $\times$ Australian feral crossbred, 50:50), average 18 kg of BW, were used in this trial, and each breed of Korean black goats was separated into conventional and TMR diets treatments in a randomized complete block design. Conventional diet was based on forages and commercial diet. All animals were housed in individual metabolism crates and were fed ad libitum. Water was available at all times. Experimental period totally lasted for 38 days, consisting of 14 days of adaptation, 10 days of preliminary period and 14 days of sample collection period. Daily dry matter intake was significantly (p<0.05) higher in TMR treatments of the crossbred goats. Within breeds, crossbred rather than native-bred consumed more highly, and within the feeding type, TMR diets were more fed in comparison with conventional diet. Average daily gain ranked the highest in crossbred : TMR, followed by crossbred: conventional diet, native-bred: TMR, and native-bred: conventional diet (p<0.05). Dry matter digestibility was significantly (p<0.05) higher for TMR than for conventional diets, and it was higher in crossbred than in native-bred Korea black goats. Nitrogen retention was highest in TMR treatments of crossbreed, whereas it was lowest in conventional diet of native breed (p<0.05). Plasma glucose and urea nitrogen concentrations were significantly (p<0.05) higher in crossbred than in native-bred Korean black goats. Overall, the results indicated that feeding total mixed ration to crossbred rather than native-bred Korean black goats had more favourable influences on their performances, intakes, digestibility, nitrogen retention and blood metabolite characteristics. In conclusion, it is conceived that the results may contribute to economical benefit to farms producing Korean black goats together with establishment of an efficient feeding management system.

The study was to determine zonal characteristics of nutrients and chlorophyll and evaluate their trophic relations in Daechung Reservoir. For this study, we compared longterm water quality data among three zones along with trophic state using 1993 to 2002 dataset, obtained from the Ministry of Environment, Korea. Total phosphorous (TP), Secchi depth (SD) and chlorophyll (CHL) showed typical longitudinal declines from the riverine to lacustrine zone, but total nitrogen (TN) was not evident. Largest seasonal variations in TP and CHL occurred during the summer monsoon from July to August. In the reservoir, ambient TN averaged 1.67 mg $L^{-1}$ and ratios of TN : TP averaged 88.04, indicating that nitrogen is not likely limited but phosphorus limitation was evident. Trophic State Index (TSI), based on CHL, TP, and SD, varied depending on the zones and seasons. Mean TSI (TP) in the riverine zone was 62 during the monsoon, indicating a hypertrophic condition, whereas the mean was 40 in the lacustrine, indicating a nearly oligotrophic. Values of TSI (CHL) showed maximum in the transition zone during the monsoon. The deviation analysis of TSI showed that about 65% of TSI (CHL)-TSI (TP) and TSI (CHL)-TSI (SD) values were less than zero and the lowest values were -42, indicating an effect of inorganic turbidity on algal growth in the reservoir. Correlation analysis of CHL vs. SD shewed greater correlation coefficient (p<0.001, r=-0.47) in the transition than other two zones (p<0.001, $r{\leq}-0.40$). Correlation analysis of TP vs. CHL was greatest in the lacustrine and TP was minimum in the lacustrine zone, indicating a lowest yield of algal biomass in the lacustrine. Overall data suggests that zonal response of chlorophyll yield at a given nutrient unit is clearly differed among the longitudinal gradients, so the management strategy such as cross sectional modelling should be provided in each zone.

The objectives of the study were to determine fish fauna and compositions during 2010~2011 in Walpyung Conservation Park along with analysis of fish community structures and trophic and tolerance guilds. Total number of species and individuals sampled were 31 and 2667, respectively and dominant species was Zacco platypus (46.6%) and subdominant species was Acheilognathus lanceolatus (8.7%), which were composed of >50% of the total. Total number of Korean endemic species including Microphysogobio yaluensis was 10 and the proportion of the individuals was 8.7%. Also, natural monument No. 454 of Iksookimia choii, which is endangered species and legal protected species, was sampled and the total number of individuals was only three. According to the analysis of fish community structures, species richness index in the mid-stream reach ($M_r$) was 3.145, which is higher than any other stream reaches ($U_r$ and $D_r$). In contrast, the richness index was 2.180 in the up-stream reach ($U_r$), which is minimum among the sampling sites. Species diversity index was 1.785 and 1.975, respectively in the headwater ($U_r$) and mid-stream reach ($M_r$) and the low values in the down-stream reach ($D_r$, 1.660) were due to the influences of pointsource (i.e., road construction) and non-point sources (sporadic agricultural spots). According to analysis of tolerance guilds, the proportion of tolerant species (TS), based on the number of individuals, was composed of 64.2% and sensitive species (SS) was only 3.3%, indicating a predominance of tolerant fishes in the compositions. The proportion of omnivore species (OS), however, was composed of 64.0% and insectivore species (IS) was 29.3%, indicating a predominance of omnivore fishes in the stream. The high proportions of tolerant and omnivore species in this stream indicates that the water quality and physical habitat environments were degradated in this system. For these reasons, especially natural monument and endemic fish species in this region should be protected from the massive constructions and required to provide efficient stream management strategies.
