In Korea, most of the locations of the cemeteries and burial vault are in forest lands. The utilization of forest land for this particular purpose is very inefficent and considered to be a serious problem. National government (Forest Service), local governments (Incheon city), and religious corporation (eunhoe Temple) are creating new burial methods to solve the inefficiency in forest utilization. In this study, awareness of Koreans and Japaneses on tree burial problems were compared. Based from the results of the survey, more than 80% of the respondents are aware of the problems. However, the burial culture in Korea still has many problems. Operation and management of tree burial is not being done by experts and sufficient information regarding to this type of burial still needs to developed. To solve these problems, eco-friendly burial, which is considered as new funeral culture, is now being created. In the case of Ichinoseki City in Iwate prefecture in Japan, improving the residential environment greatly affected the tree burial practices. This town was chosen for this study due to its characteristics of being a tourism area which greatly affecting the economy of this town. Another study site of this study was located in Sangju city. The changing social environement and the perception of the people regarding on the services being provided to the people were examined thru questionnaire survey. Specifically, this study analyzed the practices and beliefs of the people regarding the tree burial culture.

The study was carried out to examine changes of ${\alpha}$-amylase activity and free proline contents during rice germination under low temperature($13^{\circ}C$). The plant height, root length, and germination rate were investigated during seed germination under the low temperature. Those growth chracteristics were the highest in Dongjin cultiver compared with other rice cultivars. The ${\alpha}$-amylase activity of the 9 days after germination was higher in Dongjin than those of Sangju and Koshihikari cultivars. The content of free proline was increased in all rice cultivars, when the germination of rice seeds was prolonged. As a result, it was concluded that ${\alpha}$-amylase activity and free proline content of Donjin cultivar were relatively increased higher under low temperature stress than those of other rice cultivars.

Objectives: This study was taken to investigate factors related to dental caries in deciduous teeth of preschool children. Methods : this study was completed by oral examination on 623 kindergarten pupils and questionnaire on their mothers in Sangju city from April 1 to May 20, 2001. Study design is Cross-sectional Study. Results: The mean values for decayed teeth indexed(dt index), filled teeth index(ft index), and decayed and filled teeth index(dft index) was 2.46, 1.85, and 4.30 respectively. 2.05 for girl was significantly lower than 2.77 of boy in gender (p<0.01). As child ren got older, values were higher(0.7 and 2.84 of three years old, 1.6 and 4.01 of four, 2.42 and 5.02 of five) in ft and dft index(p<0.001). Also, Mother age was almost same, that is, 4.12 dft value for 30~34 years was smaller than 6.17 for above forties(p<0.001). 2.07 and 4.68 for mothers who graduated from high school were higher than 1.36 and 3.34 for university in the ft and dft index(p<0.05), that is, the more they had a high educational level, the lower they got a values. Value 2.76 for children who had non cariogenic food was lower than 5.11 for those who had cariogenic food in dft index(p<0.001). In dft index, 3.82 of children who have learned the education on oral health from mother frequently have lower than 45 of children who have never learned (p<0.05). The ft value of children who had a snack food with mother(1.29) was a smaller than children had it at out of home(1.97)(p<0.05). The variables related 10 dft index were children and mothers age, educational level, and kinds of snack food (p<0.05). Conclusion : This study reveals that younger girl, younger mother, higher educational level, and non cariogenic foods showed lower dft index.

This study was to obtain information about the dietary habits, the dietary attitudes, nutrition knowledge, and the food consumption of middle school students and to assess relationships between the dietary habits, the dietary attitudes, and nutrition knowledge of middle school students. Data were collected from 390 middle school students in Kimcheon. In the dietary habits, the regularity of breakfast showed the highest point and the snack consumption showed the lowest point. Female students were lower in the regularity of breakfast, and male students were higher in overeating of dinner and night. In the dietary attitudes and the perceived importance of nutrition, male students showed more favorable attitudes and perceived more importance of nutrition. In the nutrition knowledge, the responses to items 'Cola or cider doesn't have calories' and 'An egg contains lots of cholesterol' were the lowest point. Female students had higher knowledge than male students. In the food intake, grains, milk.yogurt.cheese, and fruits were always eaten or frequently eaten. While fast food, spicy and salty food, seaweeds, carbonated drinks, and yellow or green vegetables were eaten in lower frequency than other foods. Male students consumed more meat.ham.egg.fish, fried.stir-fried food, fast food, carbonated drinks, and spicy and salty food than female students. The correlation between dietary attitudes and dietary habits was statistically significant. The correlation between dietary attitudes and the perceived importance of nutrition was statistically significant. But the correlation between dietary attitudes and nutrition knowledge was statistically significant for female students, not significant for male students. Nutrition knowledge was related to the perceived importance of nutrition. It might be suggested that effective nutrition education program might be developed and implemented to ensure the good eating behaviors of middle school students.

Four estrus-induced Himalayan tahrs (Hemitragus jemlahicus) were inseminated with frozen-thawed semen by laparoscopic or transcervical insemination techniques with no regard to the site of ovulation in non-breeding season. In June and July, 2009, estrus was synchronized by Eazi-Breed $CIDR^{(R)}$ (Controlled internal drug release; Pfizer Animal Health, New Zealand) insertion for 16 days and PG 600 (PMSG 400IU, hCG 200 IU; Intervet, Netherlands) injection (IM) a day before removing $CIDR^{(R)}$. Forty eight hours later, laparoscopic or transcervical insemination was done to each of two tahrs under anesthetic condition inducted by ketamine (1.5 mg/kg) and medetomidine (0.09 mg/kg). For examination of estradiol and progesterone, blood was collected right before $CIDR^{(R)}$ insertion, PG 600 injection, $CIDR^{(R)}$ removal and insemination. Estradiol levels of four tahrs (No. 1, 2, 3, 4) before $CIDR^{(R)}$ insertion and insemination were 13.3, 8.8, 14.3, 12 pg/ml and 23.5, 25.5, 21.1, 11.5 pg/ml, respectively. Progesterone levels of four tahrs (No. 1, 2, 3, 4) before $CIDR^{(R)}$ insertion and insemination were 1.8, 0.05, 0.63, 0.61 ng/ml and 1.03, 0.37, 1.48, 2.12 ng/ml. Except for No. 4 tahr, cervices showed cervical mucus and opened enough to penetrate with embryo transfer gun sheet usually used for cows. Therefore, No.4 was laparoscopically inseminated together with No. 1. In conclusion, none of four Himalayan tahrs was pregnant. However, we proved that estrus could be induced by CIDR and PG 600 injection in non-breeding season, and laparoscopic or transcervical insemination with frozen-thawed semen could be one of assisted reproductive techniques in Himalayan Tahr.

For the purpose of inquiring into the actual conditions of water quality management of Simple Piped Water Supply(SPWS) and the satisfaction and attitudes of inhabitants about utilizing water-supply, this research was done through the questionnaires, the investigation of surrounding environment and water quality analysis in the Sangju city, Kyungsang-pookdo during 4 months from March to June, 1998. The fountainhead of SPES using ground water accounted for 65.3%, which was the highest rate in the group. Most of them was at least 10 years in the number of utilization year. 79.6% of them were exposed to many sorts of surrounding pollution origins. The examination of water was performed only through a test about water purification and 24.5% of them disinfection by chlorine also no residual chlorine was detected at all. All the waterworks did not have any education to the managers of water quality and 81.5% of them held physical examination. As a result of the water examination about SPWS, 65.3% of them were found incongruity and the valley and springing water accounted for higher than the underground water in the rate of incongruity. Looking into the details of the result in the water examination, a category of colon bacilli was ranked in the highest rate and the next one was general bacilli, nitric acid nitrogen and turbidity in order. In the satisfaction degree of the water quality, the satisfied accounted for 44.6%, and 29.2% each. Over the state of satisfaction about the ways of water examination, satisfaction accounted for 44.6%, and unsatisfaction 28.3%. Summarizing the result of the above-stated, the state of Water Quality Management of the SPWS was in a poor condition. Thus for the water Quality Management, systematic and scientific water Quality Management mainly by the administrative organization other than voluntary management by the village should be done beyond doubt. Additionally the opinions and demands of inhabitants utilizing the water supply have to be positively reflected in the affairs of water Quality Management so that the distrust of inhabitants to the SPWS should be settled.

The recycled asphalt concrete has gotten increasing attention due to the environmental issues. The volume of reclaimed asphalt has increased significantly for last few years because of city remodeling, pavement maintenance, utility excavation, and road widening. Considering the value of reclaimed asphalt, it is rather used for the recycled asphalt concrete than it is used for fill and cover up material instead of soil. This research will be a supplements incomplete issues from existing research results and suggests the quality control guideline for recycled asphalt concrete and upcoming laws. As the first step of research, the trial construction of RAP(Recycled Asphalt Pavement) performed in expressway construction sites. These trial construction sites have been checked every years. And another construction sites studied and selected for more deeper performance check of RAP. For this checks, we used automatic pavement survey equipment and computerized analysis tools. Also, DSR(Dynamic Shear Rheometer) was used for the fatigue life calculation of binder blends(RAP and virgin binder). As a consequence of this research, the application of recycled asphalt provides good enough quality for highway construction. The preceeding literatures reviewed shows that the asphalt rejuvenator are used in many countries but that type of chemical agent are not used in Korea. By using the data of trial construction and mix design in Chongwon-Sangju construction lane, the surface and base courses consisted with the 10% and 30% rap mix asphalt section maintains good performance for up to 7 years. Through the performance check and laboratory tests(DSR), the quality control and mixture's low temperature prevention are the important factor and chemical agent necessary for increasing the fatigue life of RAP binder.
