  • Recently since urbanization has brought about a dried stream and a worse water quality, Anyang city discharged the third treated sewage into the upper stream of Anyancheon and Hakuicheon. As the result, Hakuicheon had the water level and velocity enough for a living thing in the water to live in but water quality was worse than it had been. Therefore in case of meeting the water level and velocity of the second grade water-quality which living things in the water can live in, the discharge and water quality to secure in-stream flow must be at least 0.350 $m^3/s$ and $BOD_5\;3.2 mg/{\iota}$ respectively. In Anyancheon the water level was increased a little higher than it had been but the velocity was almost unchanged in comparison with it before. On the other hand the water quality was a little better than it had been. Therefore in case of meeting the water level and velocity of the third grade water-quality that people can do water-friendly activity, the discharge and water quality to secure in-stream flow must be at least 0.688 $m^3/s$ and $BOD_5\;4.8 mg/{\iota}$ respectively. The water-quality prediction on the suggested eight scenarios was simulated in all satisfying the third grade water-quality.

  • 중학교 도덕 교과의 환경 교육은 매우 비체계적으로 진행되어 왔다. 현행 7차 교육과정의 중학교 도덕과 교육목표에는 환경 관련 내용이 없다. 중학교 도덕 교과서 어디에도 환경 단원하나 개설되어 있지 않다. 중학교 도덕 교과서에서 환경 관련 내용들은 대부분 각 단원에서 그 단원의 핵심 내용을 설명하기 위해 도입되었다. 중학교 교과서에서의 환경 관련 서술은 목적적이지 못하고 도구적이며 부차적이다. 다행히 2007년 개정교육과정에서는 도덕과 교육 목표에 환경 관련 내용이 담겨있고, 교과서에 「환경과 도덕」이라는 단원도 신설되었다. 개정 교육과정에 따른 새로운 교과서가 집필되고 있다. 중학교 도덕교과에서도 제대로 된 환경 교육을 진행할 수 있는 계기가 마련되었다고 할 수 있다. 그러나 자세히 살펴보면, 새로운 개정 교육과정에서의 환경 교육 또한 심각한 문제점을 내포하고 있다. 환경 단원이 중학교 1학년 교과서에만 실려 있기 때문이다. 환경 교육이 중학교 1학년 단계에서만 이루어지고, 2학년과 3학년에서는 이루어지지 않을 가능성이 높다. 환경 문제는 인류의 생존과 직결된 문제이다. 중학교 2학년과 3학년에서도 그 수준에 맞는 환경 교육이 이루어져야 한다.

  • 2007년 개정 교육과정의 초등학교 3, 4, 5, 6학년 수학 교과서에는 '약속'으로 제시된 용어의 수학적 개념을 명확히 이해하는지 확인하기 위하여 '문장 만들기'가 신설되었다. 본 논문은 초등학교 3학년 학생들의 문장 만들기 활동에서 나타난 문제점을 바탕으로 문장 만들기의 역할에 대하여 논의하였다. 논의 결과, 전반적으로 교과서에 제시된 문장 만들기의 역할은 충분히 수행되지 못한 것으로 나타났다. 따라서 문장 만들기는 약속으로 제시된 용어를 실생활에서 적절하게 사용할 수 있는지를 확인하는 방안으로 활용되어야 하며, 약속의 개념을 확인하기 위한 역할은 약속의 개념에 따라 선별적으로 적용될 필요가 있었다.

The contents of all textbooks were analyzed separating into paragraph and picture, the contents for dental health were classified into amount, item, teaching method. The results are as follows: 1) The paragraphs on public health were 3.992 among total paragraphs 69,789 as 5.72%. And the picture were 7.41% as 923 pieces of total 12,457 ones. 2) For dental health, there were 73 paragraphs of 69.789 ones (0.10%) and 42 pieces of 12.457 pictures (0.34%). 3) According to the investigation of curriculum that had the paragraphs related to dental health the most, it turned out to be in order of physical education nature. Right life story, and right life story, righ life, physical education for the picture. And for the grade, it appeared to be in order of sixth, third first grade for the paragraphs and first, third, sixth grade for the pictures. 4) In the attitude and knowledge of item for dental health by grade, it turned out that the paragraph was 76.71%, the behaviour was 23.29%. On the other hand, the knowledge was 35.17% and the attitude was 64.28% for the picture. 5) At the commentary of curriculum in primary school, the goal of health education by each grade was just keep clean and strong teeth, know the role of teeth and the cause of dacayed teeth, and prevent it in second and third grade.

  • 가스배관 사고의 대표적인 원인 중 하나는 기계적 충격(타공사 등)으로 인한 사고이다. 이는 국내 주요 산업단지에 매설되어 있는 고압가스배관의 대다수가 매설 시기가 20년 이상인 노후 배관이기 때문에 사고 발생 시 별도의 검사 및 보강 시간 없이 대형 사고로 이어질 가능성이 높다. 본 연구에서는 타공사(굴착공사) 실험을 통해 기계적 충격 시 배관에 미치는 결함 정도에 대해 연구하였다. 실제 산업단지에서 굴착공사 시 사용되고 있는 21 ton 굴착기와 ASTM A106 Grade.B와 ASTM A53 Grade.B 배관을 이용해 타격실험을 진행하였다. 그 결과 굴착기 작업에 이용되는 버켓 중 톱니 버켓 일 때 결함의 정도가 더 컷으며, 매설되어 있는 배관의 관경이 작을수록 결함의 깊이 및 길이가 큰 것을 확인하였다. 굴착기 작업 중 타격 높이는 매설 배관의 결함에 아무런 영향을 미치지 않는 것을 확인하였다.

  • The aims of this study are to identify the perceptions and learning needs related to nursing profession of nursing students and to provide the basic data for development of curriculum. The questionnaire used for this study includes 103 items categorized as the fellowing 8 areas : the perception of nursing profession, competency as a nurse, the perception about clients, priorities in nursing activity, the knowledge required for, an ideology about nursing. Data was collected from the same students through their first grade in 1993 to third grade in 1995. The results are as follows : 1) In terms of the views on nursing profession, most of the students responded it as helping treatment of disease. Higher the grade, more significant with regard to health counseling, utilization of nursing and skills, nursing for community people. 2) Asked about competency as a nurse, sufficient professional knowledge on the nursing was responded as the highest. 3) Asked about the clients of nursing, 'patients' was the highest and as the grade was high, the items on 'family', 'community people', 'community' were high. 4) With regard to the points to be considered in the performance of nursing, while 'physical respect', 'psychological respect' were commonly responded, 'spiritual respect' highly responded in the second and third grades. 5) Asked about what nursing activity is, 'to relieve the pain' was high in the first and second grades, 'the promotion of health' was high in the third grade. 6) With regard to the ideology on nursing, the humanity and belief and faith were commonly responded. These results suggest, even though the expanded role of nursing was recognized, there is the tendency of illness oriented, to be need of reinforcement on the curriculum management in nursing education.

  • This study is to find out how well elementary school gardens work as places of observation learning. We compared the tree species planted in elementary school gardens with those which appeared in the science textbooks of the 7th Korean National Curriculum. The number of tree species are 60 throughout all the grades, specifically; 43 in the third grade, 22 in the fifth grade, 16 in the first grade, 15 in the second grade, 8 in the sixth grade, and 5 in the fourth grade, respectively. Their frequency of appearance (hereafter referred to as 'appearance frequency') throughout all the grades is 175, and the maximum frequency is 62 in the third grade. Of particular note is the fact that the appearance frequency in one grade was very high, meaning that a repeat study will not be conducted. The total number of tree species counted in the study was 13,028 and consisted of 167 species in 52 families. Only 23% of the total planted tree species, that is, 38 tree species appeared in the textbooks, so the ratio of the practical usage of school gardens was revealed to be low. In the school gardens, there are only an average of about 16 tree species per school. The fewest number of species in one school was 9 and the most was 22. The native species were 74 and the non-native species were 93. This means that almost all the planted species do not relate to observation learning in the textbooks. The 22 tree species among 60 species in the textbooks were not planted in the gardens. In conclusion, the degree of utilization of almost all the elementary school gardens examined during this investigation was very low.

  • The purpose of this study is to analyze of biotope types and to develop assessment for forest ecosystem evaluation method. Vegetation types divided into 27 types. Considering the vegetation types, vegetation structures, DBH, potentials, and disturbance, it was decided to apply 58 biotope types and survey site's biotopes were divided into 24 biotope types. Assessment indicators were naturaliness, diversity, rarity, stability, potential, and disturbance. The areas given the first grade in ecological value included 9.2% of the site's total land. Areas with the second grade accounted for 43.0% of the total land. Areas with the third grade made up 47.8% of the site and mostly they were areas with dominance of fired area and artificial forest. To plan to build naturally-development for Site, there should be plans to conserve areas with the first grades. For the areas with the second, and third grades, plans for ecological land use based on conservation and restoration in terms of securing biodiversity are needed.
