본 논문에서는 민감한 양적 정보를 얻기 위한 조사에서 응답자들이 정직하게 응답하기를 꺼리는 질문들에 대하여 응답자의 비밀을 노출시키기 않고서 양적 정보에 대한 보다 정확한 정보를 얻을 수 있는 양적 확률화응답기법을 인터넷 상에서 사용할 수 있도록 구현하고자 한다. 본 시스템에 DB 환경에 바탕을 두어 기존의 온라인 설문조사 시스템 및 질적 확률화응답기법과 연계하여 자료를 공유할 수 있을 뿐만 아니라 독립된 스팟 서베이(spot survey)가 가능하도록 구현하고자 한다.

The purpose of this study is to examine the actual conditions of kindergarten outdoor facilities in Korea, based on their establishment types and their located areas. The subjects for the survey were 6,819 kindergartens, and the subjects for sample-depth survey were the 10% of the total group, The study was conducted with an online survey and an on-the-spot survey, Spss 12.0 was used for statistics analysis, Most outdoor facilities of kindergartens in Korea consisted of playgrounds with soil or sand and complex playing equipments, The rate of Kindergartens' owning and utilizing their educational equipments was high. The educational utility of kindergarten outdoor facilities was high, too, but the needs of public kindergartens and that of private kindergartens were different. The 3% of private kindergartens had playgrounds on the roof, so they needed to be inspected periodically by the authorities. The kindergartens attached to the primary schools needed independent playgrounds of primary schools, Most kindergartens are required to explore diverse paving materials of their playgrounds and to develop outdoor equipments for childrens' creative playing.

The importance of professor's outline in a feedback instruction was examined through various documents and the way in which the evaluation was fulfilled in Korean educational environment and its reflection upon the evaluation result were investigated by means of research. Based upon the survey results in connection with the progress and basis of teachers' on the spot feedback mathematics instruction in schools, it was found that most of teachers who engaged in feedback mathematics instruction were going over the most frequently missed problems. I proposed that we should bring up the point at issue and grasp its tendency of a class and entire group's results by means of a relative comparative analysis method, and thereupon establish a fixed category and choose substantial feedback scholarship according to that category. From this basis, the sub-sequent research topics include the substantial feedback effects of the selected problems that should be given priority, a group analysed and classified by means of comparison of tendency as well as feedback outline depended on students' characteristic, and the determining factors of tendency(a condition of professors, a level of students, geographical difference(s), and gender difference(s), etc...).

In this paper, we investigated a dust pollution and spot survey of electrical installation in vulnerable area. From the survey results, we know that the dust was easily accumulated in cabinet panel because the cabinet panel cover was opened and the management of installation was not good. Although the dust pollution was not difference, the possibility of accident become increased by dust in salt area. Thus, it is necessary to variation of cabinet panel shape to prevention of electrical disaster in dust occurrence and another protection devices.

This study was conducted to investigate the concern of the primary school teachers and the teaching situation about the environmental education through questionnaire survey on the effective environmental education. The results of questionnaire were analysed and discussed to provide the effective teaching method for the environmental education. The result of this study is as follows. 1. It was found that teachers want to teach environmental lessons as a special subject, and the content of the environmental lessons in textbook was not enough in quantity, the living waste was the most serious ploblem. Owing to the lacking in materials for the lectures on environmental education, most teachers collect the material depending on the mass communication. Also they were more interested in the environmental lessons rather than the other lessons in textbook. But because of the lacking in administrative assistance, they have difficulty in conducting the effective environmental education. 2. The teaching method of the environmental education in most primary schools was a all together-type lecture in classroom. Owing to conducting the environmental education for the knowledge than the action through the extra activity, it was difficult to expect the effect of the environmental education. Also the rate of using the reflection materials which can be improved the studying effect was very low. 3. For the effective environmental education most teachers wanted the spot learnings and the case studies and teacher education and training to get an special knowledge for environmental education. The effective evaluation method for children's environmental education is to present the results by environmental experiences and practices and to formulate a system education is organized for the effective management and activation of environmental education. 4. By practising the seasonal spot learnings, students need to change of learning method and to realize the importance of environment through own self-experiences. 5. In the future, it is desirable that researching of an environmental education is offered the effective practising teaching method which is improving the development of customs and functions, cultivation of the sense of value, ability to solve the problem, to determine the intention as well as the survey on the real situation and the consciousness about environmental education.

In several schistosomiasis-endemic countries, the prevalence has remained high in some areas owing to reinfection despite repeated mass drug administration (MDA) interventions; these areas are referred to as persistent hot spots. Identifying hotspots is critical for interrupting transmission. This study aimed to determine an effective means of identifying persistent hot spots. First, we investigated the differences between Schistosoma haematobium and Schistosoma mansoni prevalence among school-aged children (SAC) estimated by a community-based survey, for which local key informants purposively selected communities, and a randomly sampled school-based survey. A total of 6,225 individuals residing in 60 villages in 8 districts of North Kordofan, Blue Nile, or Sennar States, Sudan participated in a community-based survey in March 2018. Additionally, the data of 3,959 students attending 71 schools in the same 8 districts were extracted from a nationwide school-based survey conducted in January 2017. The community-based survey identified 3 districts wherein the prevalence of S. haematobium or S. mansoni infection among SAC was significantly higher than that determined by the randomly sampled school survey (e.g., S. haematobium in the Sennar district: 10.8% vs. 1.1%, P<0.001). At the state level, the prevalence of schistosomiasis among SAC, as determined by the community-based survey, was consistently significantly higher than that determined by the school-based survey. Purposeful selection of villages or schools based on a history of MDA, latrine coverage, open defecation, and the prevalence of bloody urine improved the ability for identifying persistent hot spots.

목 적 : 전산화 단층촬영장치는 방사선을 이용한 질병의 진단에 중추적인 역할을 하는 장비이다. 시대의 흐름과 과학기술의 발달로 전산화 단층촬영장치도 그 발전을 거듭해왔고 앞으로도 전산화 단층촬영장치를 이용한 검사는 더욱더 증가하리라 생각된다. 검사의 증가와 함께 산란선에 노출될 기회가 많아질 것이라는 생각 또한 사실이다. 이에 전산화 단층촬영실의 제어실내 환자 보기창 앞과 환자 및 보호자들이 출입하는 출입문 외측 그리고 환자 검사 시 촬영실내에서의 산란선 발생률을 측정하였고 산란선의 피폭을 가장 최소화 할 수 있는 방법을 알아보고자 하였다. 대상 및 방법 : 2001년 11월부터 서울소재 13개 종합병원 및 대학병원에 설치 운용중인 전산화 단층촬영장치 25를 대상으로 하였다. 촬영조건은 피폭선량 측정시 제조업소에서 권고 하고있는 촬영조건을 사용하였고, 이때 피사체는 피폭선량 측정용 DALI CT 피폭선량 측정용 두부용 팬톰(${\phi}16\;cm$ Plexglas)과 복부용 팬톰(${\phi}32\;cm$ Plexglas)을 사용하였다. 산란선의 측정은 환경방사선 측정용 Survey Meter인 Radical Corporation, model $20{\times}5-1800$, Electrometer/Ion chamber, S/N 21740에 Reader(Radiation Monitor Controller model 2026)과 G-M Survey를 이용하였다. 산란선의 측정위치는 전산화 단층촬영실에서 방사선 작업종사자가 주로 활동하는 제어실내 환자 보기창 앞과 환자 및 보호자들이 출입하는 출입문 외측 그리고 피사체 스캔시 등선량중심점(isocenter)으로부터 100 cm되는 지점에서 측정하였다. 결 과 : 각 병원에서 설치 운용중인 전산화 단층촬영실내 작업환경은 해당병원의 상황에 따라 많은 차이를 보이고 있었고 산란선의 발생유무는 다음과 같았다. 1) 전산화 단층촬영장치의 등선량중심점(isocenter)에서부터 제어실내 환자 보기창 사이의 거리는 평균 377 cm이였고 이때 산란선은 거의 검출되지 않은 곳에서부터 약 100 mR/week까지 다양한 분포를 보였으나 주당 허용선량인 $2.58{\times}10^{-5}\;C/kg$(100 mR/week)이내의 조건을 만족하고 있었다. 2) 전산화 단층촬영장치의 등선량중심점(isocenter)에서부터 환자 및 보호자가 출입하는 출입문 외측까지의 거리는 평균 439cm이었고, 이때 산란선은 거의 검출되지 않은 곳부터 다양한 분포를 보였으나 대부분의 병원에서 주당허용선량인 $2.58{\times}10^{-6}\;C/kg$(10 mR/week)이내의 조건을 만족하고 있었다. 3) 피사체를 스캔할 때 등선량중심점(isocenter)에서부터 100 cm되는 곳에서의 산란선량은 장비에 따라 많은 차이가 있었다. 결 론 : 진단용 방사선발생장치에서 전산화 단층촬영장치의 이용은 나날이 증가하고 있고 다른 일반 X-선 촬영과 비교했을 때 진단영역이 매우 높지만 방사선으로 인한 피폭과 산란선에 노출될 가능성이 매우 높다. 전산화 단층촬영실에서 산란선으로부터 조금이라도 자유로워지기 위해서는 설계단계에서부터 충분한 공간 확보가 우선되어야하고 모든 검사에서 방사선사는 최소의 선량으로 최상의 영상을 제공할 수 있는 다양한 기술개발에 더욱 노력을 아끼지 말아야 할 것으로 생각된다.
