이 연구는 농업ㆍ농촌의 기능과 가치를 재정립하고 이를 초등학교 교육과정 및 교과서에 반영시킬 수 있는 방안을 제시하는데 그 목적이 있었다. 이를 위하여 먼저 선행연구 고찰을 통하여 농업ㆍ농촌의 기능과 가치를 재개념화하고, 이를 토대로 내용 분석 틀을 개발하여 초등학교 교육과정 및 교과서를 분석 하고, 그 결과를 토대로 교육과정 및 교과서에 반영시키기 위한 방안을 제시하였다. 그 주요 결과는 다음과 같다. 첫째, 농업ㆍ농촌의 기능과 가치는 크게 자연환경적 기능(수자원 함양 기능, 환경정화 기능, 생태계 보전기능, 자연재해 방지 기능), 사회문화적 기능(전통문화 보전 기능, 정서의 순화 기능, 자연학습의장 제공 기능), 사회경제적 기능(농산물 공급 기능, 직업 기회 제공 기능, 국토의 균형발전 기능, 타 산업에의 기여 기능)으로 분류하였다. 둘째, 농업ㆍ농촌의 기능과 가치를 바탕으로 초등학교 교육과정 및 교과서를 분석한 결과, 전 학년에 걸쳐서 자연학습의 장 제공 기능과 전통문화 보전 기능이 높게 나타났고, 그 다음으로는 농산물 공급기능과 정서순화기능이 높게 나타났다. 반면에 수자원함양기능과 환경정화기능은 상대적으로 낮게 나타났다. 셋째, 내용분석을 토대로 교과의 성격을 고려하여 각 교과별로 농업ㆍ농촌의 기능과 가치를 반영시킬 수 있는 방안을 제시하였다. 마지막으로, 각 교과별로 농업ㆍ농촌의 기능과 가치 반영 방안을 체계적으로 이행하기 위한 행ㆍ재정적 지원 방안을 교육과정 개발 측면, 교과서 개발 측면, 교육과정 운영측면, 정책적 지원 측면으로 구분 하여 제시하였다. The purpose of the study is to suggest the strategies for incorporating the roles and values of agriculture & rural areas as a part of the national curriculum and elementary school textbooks. For this purpose, this study was conducted as follows; First, we reclassified the roles and values of agriculture & rural areas after critically reviewing literature: environmental conservation functions, socio-cultural functions and socio-economic functions. Second, based on the new classification, we develop a framework for analyzing the national curriculum and elementary school textbooks. The functions of rural areas as places for learning about nature and purifying emotion and the importance of agriculture in providing agricultural product were frequently presented but the functions of sustaining water resources and environmental purification were relatively less presented in the national curriculum and elementary school textbooks. Third, we suggested strategies for incorporating the roles and values of agriculture & rural areas in the national curriculum and elementary school textbook based on the analysis. Finally, we suggested necessary administrative and financial assistance to systematically and effectively implement the suggested strategies for developing a new curriculum and textbooks as well as implementing the curriculum.

The aim of this research is to characterize the waste concrete which is generated in large quantities in construction fields. In order to achieve this aim, htis research analyzes the engineering properties of recycled aggregate cnocrete classified by the factors such as aggregate composition and W/C. From the experimental results, it was found that the recycled aggregate concrete is rather good compared to general concrete in terms of workability and engineering properties. Besides, the reliable regression analysis equations between compressive strength and various experimental data for recycled aggregate concrete are presented. As a conclusion, this study shows that the recycled concrete is expected t4o be economically useful and also brings about positive result in aspect of environment.

The purpose of this study was to investigate the interaction patterns between teachers and students appeared in sixth grade elementary science lessons. To this end, we set research questions as what are the types of SPS (Social Participation Structure) between teachers and students in the class. Eighteen elementary science lessons were observed. Data were collected by video recordings and observation method. The result showed that the types of SPS were classified into nine. 1) A teacher initiates the whole students into interaction with him. 2) The whole students keep silent or carry out specific activities under the teacher's direction. 3) A teacher initiates some students into interaction. 4) A teacher names specific students to read a text. 5) A teacher initiates the whole students into group interactions. 6) Students interact with each other irrespective of the teacher's intention. 7) Students initiate a teacher into interaction with them. 8) A teacher intervenes during the students' activities and this intervention, in turn, produces interactions between the teacher and the students. 9) A teacher directs the whole class to read a learning goal or a learning material. This study shows that SPS-1 and SPS-3 are the most frequently observed interaction patterns in the elementary science lessons.

Background: Good documentation of electrical injuries at the time of presentation is very important to emergency management, so this study was designed to investigate the clinical characteristics and the outcomes of patients with electrical injury. Methods: A review of 75 cases of electrical injuries admitted to our hospital via the emergency department over a 4 year period from 1996 to 1999 was conducted. Results: There were 49 patients with high-voltage injuries and 19 patients with low-voltage injuries. All but 4 patients were males, with a mean age of 29.5 years. The most common type of injury was electrothermal burn. The most common point of entry was hand. The average size of burn wounds was 14.5% TBSA in the high-voltage group and 2.5% in the low-voltage group. Forty-nine(72.1%) of the injuries were work related. The number of patients with compartment syndrome was 19, and fasciotomies were performed in all but one patient. Myoglobinuria was noted in 22 patients, but no patient developed acute renal failure due to myoglobinuria. In the high-voltage group, 10 limb amputations were performed. Complication were observed in 12 patients. The most common complication was neurological injury. The average length of hospital stay was 50.7 days in the high-voltage group and 13.8 days in the low-voltage group. The overall mortality rate was 4.3%. Couclusion: Prevention of electrical injuries is very important. Education and compliance with safety measures, as well as basic knowledge and precaution in dealing with electricity, are essential to avoid these injuries.

It is known that lactic-acid bacteria (LAB) helps keeping the intestine healthy and to enhance its immunologic competence. In addition, it is known to control the composition of the enterobacteria and the intestinal inflammatory reaction by inducing immunological enhancement. This study was performed, in a mouse model, to test the treatment and preventive effects of LAB of inflammatory bowel disease (IBD), which was induced by a blend of LAB-administering trinitrobenzene sulfonic acid (TNBS). To obtain the animal model of IBD, 2% TNBS was rectally administered once to a five-week-old male Balbc/J mouse. A probiotic combination was administered to the prevention group five times a week for eight weeks before the inducement of enteritis, and the mixture was administered to the treatment group five times a week, after the administration of TNBS. The changes in the levels of the cytokines of the lymph nodes and the tissue of the large intestine were observed, both with the naked eye and with a microscope. The observation showed that the levels of inflammatory cells, infiltration, and necrosis were much lower in the LAB-administered groups than in that of the control group. In addition, the inflammatory cytokines (e.g., TNF-${\alpha}$, IL-17A) decreased in the lymph nodes and the tissues of the large intestine. The results indicated that the administration of the combination to the animal model suppressed the inflammatory cytokines in the large intestine and in the lymph nodes, which in turn suppressed the progression of colitis.

The use of lactic-acid bacteria (LAB) is effective for preventing and curing immune disorders by activating the immune system in the digestive tract and the consequent immune response in the blood. In this study, LAB and mixed LABs were used in an atopic dermatitis (AD) mouse model. Alleviation of AD was observed based on the change in cytokine level and immunohistochemical staining. An ex vivo test showed that immunoglobulin-E and interleukin (IL)-4 levels were significantly lower in all groups treated with LAB than in the group treated with only 1-chloro-2,4-dinitrobenzene. Results of an in vivo test based on the ex vivo results showed that the scratch score decreased in all groups treated with the LAB and particularly decreased in the group treated with mixed LABs. Additionally, the T helper (Th) 1 cytokines interferon-gamma and IL-12p40 were upregulated by the LAB and mixed-LABs, whereas levels of the Th2 cytokine IL-4 were downregulated in a mouse model of AD-like skin lesions. Furthermore, hematoxylin & eosin and immunohistochemical staining of the dorsal area of the mice in each group showed that AD improved in the LAB-treated groups. These results suggest that LAB and mixed LABs inhibit the development of AD in NC/Nga mice by suppressing the Th2 cell response and increasing the Th1 cell response. Our results indicate that mixed LABs are better than LAB for treating AD-like skin lesions.
