In order to detect the safety and effect of various aqua-acupunctures from Scutellariae Radix, the modifications of boiling, filtration and dilution were employed for the manufacture of aqua-acupunctures. We injected 0.2cc of aqua-acupunctures into Joksamri(足三里) of rat, repeatedly. we compared subacute toxicity of them with saline group, distilled water(D.W.) group, acupuncture group and control group. The results were summarized as follows: 1. The groups were all healthy and alive, and there was no special abnormality in physical condition and autopsy. And there were not any toxic symptoms in repeating application of aqua-acupunctures to the rat, including changes of body weight, organ weight, haematological examination and serum biochemical test. 2. There was slight change of body weight in acupuncture group : We could see significance after 3 days (p<0.05) and after 7 days (p<0.001) in body weight loss. After 9 days, all tested groups were suppressed in body weight increment. 3. Result of organ weight: In Palking aqua-acupuncture(D-2 group), saline group and acupuncture group there were some statistical significance. Especially, acupuncture group revealed significant result in liver and spleen than aqua-acupunctures. From this result, we could suggest that the efficacy of acupuncture was preceded herbal medicine. 4. In serum biochemical test, we examined glucose(GLU), triglyceride(TG) and cholesterol(CHOL). In comparison with control group, the diluted 10 times of hwanggum aqua-acupuncture (× 10 group) was recognized significant decrease of glucose, but the diluted 100 times of Hwanggum aqua-acupuncture (× 100 group), D-2 group, saline group were confirmed significant increment. There was not any meaningful change of CHOL in all of tested group, excepting the acupuncture group was exhibited statistically significant decrease(p<0.05). In TG level all tested group except complex injection of standard compound (CPA group) and HG, there were significant value in statistically. The diluted solution was more significant decrease than Hwanggaum aqua-acupuncture(HG). The mutual relationship of components of aqua-acupuncture tended to decrease level of TG, regardless of its concentration. In acupuncture group, we gained some interesting result in meaningful decrease in TG. 5. Haematological examination showed significant increment of gramulocytes(GR) in all tested groups except Hwanggum aqua-acupuncture. And the diluted solutions of HG expressed very high increment of them(p<0.001). The GR and Mean Corpuscular Volume(MCV) of acupuncture group showed statistical significance.

Thin films of Zinc Oxide were prepared by using a spray technique. Organometallic solution was sprayed the glass substrates at 200℃, 225℃, 300℃ and 350℃. Film thickness was controlled to be about 700㎚. The structures and surface states of films were examined by electron microscopy and by X-ray diffractoin. The results of X-ray diffraction analysis showed that poly crystal films of ZnO have been successfully deposited at 200℃.

Objective: The purpose of this study is to examine the susceptibility of the patients diagnosed by rheumatoid arthritis to Sasang Typology. Methods: This study are planned to detect the susceptibility of the patients diagnosed by rheumatoid arthritis to Sasang Typology. In order to analyze the susceptibility of rheumatoid arthritis to Sasang Typology, 147 rheumatoid arthritis patients and 147 matched controls are assessed with QSCCⅡ question for Sasang Typology. Then the frequencies of patients by Sasang constitution are compared to those of control, which are statistically analyzed and adjusted by age, sex, smoking status, alchol intake, BMI, and economic status. Results: The demographic characteristics of the study population are similar in sex and age distribution, smoking status, and alcohol intake(p>0.05). 147 rheumatoid arthritis patients and 147 matched controls are assessed with QSCCⅡ question for Sasang constitution. Soeumin is die most susceptible to rheumatoid arthritis compared to Taeumin or Soyangin(Crude OR [95% Cl] ; 3.82 [2.19-6.64]). lt is statistically significant after adjusting age, sex, smoking status, alcohol intake, BMI, and economic status(Adjusted OR [95% Cl] ; 3.01 [1.47-6.15]). Conclusions: lt is suggested that the specific Sasang Typology associated with rheumatoid arthritis is used as its susceptibility marker and further as basic date to prevent the risk factors for rheumatoid arthritis.

과학적 태도에 따른 중학생의 학교 과학수업과 학원 과학수업에 대한 만족도 비교

본 연구는 학교 과학 교육과 학원 과학 교육의 활성화와 바람직한 방향 설정을 위한 기초 자료를 제공하기 위해 중학생들의 과학적 태도에 따른 학교 과학 수업과 학원 과학 수업에 대한 인식을 조사 및 분석하였다. 분석 결과, 학생들은 학교 과학 교사보다 학원 과학 강사를 더 친근하게 인식하고 있었으며 자신들에게 더 많이 관심을 가지고 있다 인식하였다. 그리고 학생들은 수업목표 제시나 수업과 관련된 여러 가지 자료 제시는 학원보다 학교에서 더 잘 이루어진다고 인식하고 있었으며 과학 현상이나 개념에 대한 스스로 생각할 수 있는 기회 역시 학교 과학 수업이 더 많다고 인식하고 있었다. 또한 학생들은 학교 과학 수업보다 학원 과학 수업에 더 집중하며 모르는 내용에 대해 질문을 더 많이 한다고 답하였고 학습평가의 경우 학교 과학 수업과 학원 과학 수업 모두 진단평가 보다는 형성평가와 총괄평가에 치중해 있는 것으로 조사되었다. 또한, 과학적 태도 점수를 상․중․하로 나누어 학교 과학 수업과 학원 과학 수업 중 어디에 더 만족하는지를 조사해 본 결과 과학적 태도 점수가 우수한 학생들은 학원 과학 수업에 더 만족하였다. 그러나 과학적 태도 점수가 중․하인 학생들에 비해 그 만족도가 낮은 편인 걸 봐서 학원의 경우 학생들의 과학적 사고나 태도를 촉진하는 수업보다는 주입식 수업으로 인해 과학적 태도가 높은 학생들의 만족도가 낮을 것이며 학교의 경우 실험이 학생들의 호기심과 과학적 태도를 향상시켜 줄 수 있는 자유로운 실험이 되기보다는 수행평가와 같은 성적을 측정하는 도구로 밖에 이용되지 않음을 알 수 있었다. The purpose of this study was to examine the relationship between the science attitude of middle schoolers and their satisfaction level with science lessons provided by school and academy in an effort to bolster public and private science education and determine some of the right directions for that. The subjects in this study were 172 middle schoolers who attended five different private cram schools in Dalseo-gu, Daegu. After a survey was conducted, randomly selected 25 students were interviewed. Their satisfaction level was analyzed in terms of relationship with teachers, teaching methods, learner class participation and evaluation, and their science attitude scores were compared and categorized into three groups. The students found themselves to be on more friendly terms with the cram school science teachers than with their school science teachers. They considered the former to be more interested in themselves, and put their schools above the academies in terms of presenting instructional objectives and relevant materials. They also believed that the schools gave them more opportunities to think of scientific phenomena or conception on their own. They stayed focused better in the academies than in the schools, and asked more questions in the academies. As to evaluation, both of their schools and academies leaned toward formative or summative evaluation rather than diagnostic evaluation. The students were divided into three different groups according to science attitude scores, and how much each group was satisfied with science instruction offered by the schools and academies was checked. As a result, the students who got higher scores in science attitude were more gratified with the academies. The others who got intermediate or low scores were more satisfied with the academies as well, which taught them to grasp the point of instruction and solve past examination questions so that they could boost their scores in science. As a study established that younger graders fell behind in science attitude, both schools and academies should try to teach students to improve the attitude of students toward science without letting them remain indifferent to that

This study was carried out to evaluate the status of the groundwater quality for paddy fields irrigation in Korea. Water samples were collected at 130 sites throughout the country. Samples were collected at three seasons-April, July and October-in 2000. According to our survey, the groundwater was found to be suitable for irrigation purpose. Average EC was shown 0.286 dS/m. Nitrate-nitrogen and Cl^(-) concentration was 5.6 ㎎/L, 32.95 ㎎/L which satisfied the Korean Standards for Irrigation Water. Nitrate-nitrogen concentration in each province was shown as following orders: Jeju (11.17 ㎎/L) > Chungnam (8.16 ㎎/L) > Gyeongbuk (6.64 ㎎/L) > Gyounggi (5.91 ㎎/L) > Chungnam (4.95 ㎎/L) > Gyeongnam (3.91 mgk) > Jeonbuk (3.50 ㎎/L) > Jeonnam (3.27 ㎎/L) > Gangwon (2.91 ㎎/L). The concentration by sampling seasons were October (6.62 ㎎/L) > July (5.88 mg&) > April (4.78㎎/L). As the soil of Jeju Province is usually derived from volcanic ash soils mainly used for upland drops, it may influence the nitrate-nitrogen concentration of groundwater. The amount of rainfall also influence the water quality. But the COD_(Cr), were shown April (3.17㎎/L) > July (2.91 ㎎/L) > October (2.40 ㎎/L), it is highly related in the basal dose of organic matter fertilizers. This study demonstrated that groundwater quality was suitable for irrigation, but continuous monitoring is recommended for agricultural policy and developing OECD agricultural environment indicators.
