The varation of thermal diffusivity with respect to rolling reduction is experimentally determined by flash technique. Copper alloy is used as an experimental material and specimens are cut from the slab produced by rolling process with different percent reduction in thickness along the rolling direction and with 30°, 60° and 90° angle to the rolling direction. It is found that thermal diffusivity is slightly decreased as rolling reduction increased and it has tendency that thermal diffusivity is increased slightly as its angle approached to 90° at same rolling reduction.

This research attempts to reexamine the schematic chronology previously presented, and to provide an alternative focusing more on the transformation and spatial distribution of stone arrowheads in Seoul and Gyeonggi-do Province during the Bronze Age of Korea. There has little been studied on stone arrowheads in Bronze Age compared with pottery, which led to a lack of understanding of change in forms, further in the transformation of stone arrowheads. As a result, the current chronology of stone arrowheads is placed in an oversimplified situation, simply classified as a triangular-, a single-, and a double-stemmed arrowhead. Most of analyses tend to only regard a stone arrowhead as a representative artifact, even though researchers acknowledge the complex and diverse relationships between the schematic transformation divided into the three phases and the form and frequency of stone arrowheads. I avoid setting typology of stone arrowheads based on a single attribute, and examine the temporal and spatial distribution of combined attributes of arrowheads in order to present an alternative that can show complexity and diversity in the development of stone arrowheads. I first classify four forms of stone arrowheads, Type Ⅰ, Ⅱ, Ⅲ, and Ⅳ, based on a shape, a type of neck, and a way of combining with an arrow-shaft, and then categorize four forms of arrowheads in accordance with “style”. The analysis shows notable change in frequency chronologically between the four types of stone arrowheads. In other words, the stone arrowheads have had the long-term transformation continually during the Bronze Age. I suggest, however, that there should be the transformation spatially, as well as the temporal change. Several attributes with meaning of time have clearly observed the distinction more in the spatial distribution. Especially, Type Ⅱ4 in general known as a transitional type linking a single- and a double-stemmed arrowhead in pervious studies has been identified as being existed in Gyeonggi-do Province from early Bronze Age. In addition to this, I argue that setting a representative artifact, based on a single attribute requires attention due to change in frequency that arrowheads are found. The result of seriation shows that diverse types of stone arrowheads have continued and co-existed with a different life cycle. 본고는 청동기시대 전-중기 서울ㆍ경기지역 마제석촉을 대상으로 기존에 제시된 편년안을 재검토하고, 시간의 추이에 따른 변화 양상 및 공간적인 분포상을 살피었다. 청동기시대 연구는 토기를 중심으로 한 유형을 설정하여 시간적인 양상과 더불어 공간적인 경계를 추정해 왔다. 그 과정에서 석기는 시간의 흐름에 따른 변화상을 간취하기 어려워 편년 연구에 보조 자료로 이용되어 왔다. 현 청동기시대 석촉 편년안은 큰 틀에서 무경촉-이단경촉-일단경촉으로의 시간적 순서상이 제시되었다. 그러나 경부의 존부 및 형태를 기초로 한 무경촉, 이단경촉, 일단경촉이라는 대형식이 광역적으로 사용되면서 석촉의 세부적인 형태 변이나 변화 양상에 대해서는 구체적으로 규명되지 못하였다. 더욱이 여러 연구에서는 이들 종류가 시간의 흐름에 따라 빈도 변화함을 어느 정도 인지하고 있음에도, 실제 분석 과정에서는 개별 형식을 특정 시기로 대표하는 표지로 확정하는 경향이 있다. 이와 같은 문제 인식에 따라 단일한 속성에 근거한 형식 설정을 경계하고, 기존의 광역적인 편년을 재검토하여 다양한 형식의 석촉이 시ㆍ공간적으로 차별적인 양상을 보이며 다층적으로 존속하였음을 밝히고자 하였다.

김영은,조윤경 이화여자대학교 특수교육연구소 2007 특수교육 Vol.6 No.2
우리나라 취학 전 장애아동 교육현장에서 통합보육 서비스는 양적으로 급속한 증가 양상을 보이고 있다.그러나 통합보육을 실행하는데 있어 시설을 운영하는 원장과 실제 장애아동 교육을 담당하는 교사들은 통합보육에 대한 지원체계의 미비로 질적인 서비스를 제공하지 못하고 있는 것으로 나타나고 있다.따라서 본 연구에서는 교육과정 운영과 행정적․제도적 지원 면에서 통합보육에 대한 지원 실태와 현재의 만족도를 알아보고,이와 더불어 지원욕구를 파악함으로써 좀 더 적절한 통합지원체계 구축을 위한 기초 자료를 제시하고자 한다.또한 원장과 교사는 각자의 입장에 따라서 통합보육 지원체계를 보는 시각이 다를 수 있으므로,종합적인 현황을 파악하고자 이 두 집단을 비교하였다.서울․경기․강원 지역의 통합 보육시설 원장과 장애 전담교사 각 136명 총 272명에 대한 설문 분석 결과,통합보육에 대한 교육과정 운영과 행정적․제도적 면에서의 지원서비스는 이루어지고 있었으며,이에 대한 원장과 교사집단 모두 만족도는 상당히 낮았으나 통합보육지원에 대한 욕구는 높게 나타났다.또한 원장집단은 교사집단에 비해 지원욕구도 높고 만족도도 높은 것으로 나타났는데 이는 통합보육에 대한 원장집단의 주도성을 반영한다고 보여 진다.이러한 연구 결과를 바탕으로 1)통합보육에 대한 지원 만족도를 높일 수 있는 질적인 지원체계의 정립,2)통합보육의 질적 향상을 위한 다양한 지원체계 구축의 필요성,3)통합보육을 위한 원장,교사 및 전문가간의 협력 체제 방안의 개발 및 지원의 선행에 대한 논의가 제시되었다. The inclusive educare services have been dramatically increased in early childhood education area. But the directors and teachers in the inclusive educare services didn’t think they would provide the qualitative services for preschoolers with special needs. Therefore, this study was intended to survey the present conditions of the supports and the satisfactions for the inclusive educare services in the curriculum management and the administrative-systematic aids. According to these data, the study were to suggest the basic information of the inclusive educare services to make more adequate system. And the important agents of the inclusive educare services, directors and teachers, might be different from each other in the recognition of support system, so this study would compare the these two groups. The directors and the teachers said they were provided with the most inclusive educare supports in all areas, but they showed the low degree of satisfaction. On the contrary, they expressed the high degree of support needs. The director group expressed the higher satisfactions and needs. This phenomenon meant that teacher group was passive, and the director group was initiative in the inclusive educare service implementation. Based on these results, the necessity of providing the more qualitative inclusive educare supports and the establishment of adequate support system were suggested.

본 연구에서는 최적일치법(Optimal Matching Method)을 활용하여 초등교사의 경력을 분석하고자 하였다. 이를 위해 초등교사 경력의 하위범주를 ①정교사, ②기간제, ③학업, ④휴직, ⑤휴학, ⑥교사외 직업, ⑦무직, ⑧장학사(관), 연구사(관), ⑨교장, 교감, ⑩ 기타의 10개로 구분하여 남자, 여자 교사 대상으로 분석한 결과, 이들의 경력개발 경로 유형이 각각 4, 3개의 고유한 유형으로 구분되는 것으로 나타났다. 연구 결과를 통하여 얻어진 결론은 다음과 같다. 첫째, 초등학교 남자 교사의 경우, ① 임용 및 휴직 후 교사 유지형, ② 기간제 후 교사 유지형, ③ 타 직업에서 교사 전환형, ④ 졸업 후 정교사 유지형 등의 4개 유형이 확인되었다. 둘째, 초등학교 여자 교사의 경우, ① 무직 후 교사 유지형, ② 타 직업에서 교사 전환형, ③ 정교사 임용, 휴직 후 정교사 유지형 등의 3개 유형이 확인되었다. 셋째, 초등교사의 각 연령대별로 경력개발을 위한 지원이 요구된다. 경력개발 경로분석에서의 엔트로피를 분석한 결과, 남자 교사와 여자 교사 모두 개인별로 서로 다른 경력을 보이지 않고 비슷한 경력을 보이기도 하지만, 개인별로 서로 다른 경력을 보이기 시작하는 시기에는 연령에 부합하는 경력개발 지원이 요구된다. The purpose of this study is to identify and describe the career patterns of education and career of the primary school teachers in Korea. Data from survey is analyzed by applying optimal matching method and clustering analysis. Results of this study are as follows. Firstly, career patterns of male teachers cluster 4 types: ‘Cluster 1: Continuous regular teachers status after appointment and layoff ’, ‘Cluster 2: Continuous regular teachers status after short-term teaching positions', ‘Cluster 3: Change of job', ‘Cluster 4: Regular teachers after university graduation’. Secondly, career patterns of female teachers cluster 3 types: ‘Cluster 1: Continuous regular teachers status after unemployment’, ‘Cluster 2: Change of job’, ‘Cluster 3: Regular teachers after university graduation. Third, primary school teachers' career development support for each age group are urgently needed

Exposed dose of young child should be managed necessarily. Young child is more sensitive than adult of a Radioactivity, especially, and lives longer than adult. Must reduce exposed dose which follows The ALARA(As Low As Reasonably Achievable)rule is recommended by ICRP(International Commission on Radiological Protection)within diagnostic useful range. Therefore, We have to prepare Pediatric DRL(Diagnostic Reference Level) in Korea as soon as possible. Consequently, in this study, wish to estimate organ dose and effective dose using PCXMC Program(a PC-Based Monte Carlo Program), and measure ESD(Entrance surface dose)and organ dose using Glass dosimeter, and then compare with DRL which follows EC(European Commission)and NRPB(National Radiological Protection Board). Using glass dosimeter and PCXMC programs conforming to the International Committee for Radioactivity Prevention(ICRP)-103 tissue weighting factor based on the item before the organs contained in the Chest, Skull, Pelvis, Abdomen in the organ doses and effective dose and dose measurements were evaluated convenience. In a straightforward way to RANDO phantom inserted glass dosimeter(GD352M)by using the hospital pediatric protocol, and in a indirect way was PCXMC the program through a virtual simulation of organ doses and effective dose were calculated. The ESD in Chest PA is 0.076mGy which is slightly higher than the DRL of NRPB(UK) is 0.07mGy, and is lower than the DRL of EC(Europe) which is 0.1mGy. The ESD in Chest Lateral is 0.130mGy which is lower than the DRL of EC(Europe) is 0.2mGy. The ESD in Skull PA is 0.423mGy which is 40 percent lower than the DRL of NRPB(UK) is 1.1mGy and is 28 percent lower than the DRL of EC(Europe) is 1.5mGy. The ESD in Skull Lateral is 0.478mGy which is half than the DRL of NRPB(UK) is 0.8mGy, is 40 percent lower than the DRL of EC(Europe) is 1mGy. The ESD in Pelvis AP is 0.293mGy which is half than the DRL of NRPB(UK) is 0.60mGy, is 30 percent lower than the DRL of EC(Europe)is 0.9mGy. Finally, the ESD in Abdomen AP is 0.223mGy which is half than the DRL of NRPB(UK) is 0.5mGy, and is 20 percent lower than the DRL of EC is 1.0mGy. The six kind of diagnostic radiological examination is generally lower than the DRL of NRPB(UK)and EC(Europe) except for Chest PA. Shouldn't overlook the age, body, other factors. Radiological technician must realize organ dose, effective dose, ESD when examining young child in hospital. That's why young child is more sensitive than adult of a Radioactivity.

A mathematical model of a passive and an active landing gear has been developed and a special program for parametric analysis was also developed. The model includes theoretical subsonic aerodynamics; first mode wing bending and torsional characteristics; oleo-pneumatic shock strut with fit and binding friction; series-hydraulc control; tire deflection; antiskid braking; run-away roughness. Analytical results shows excellent correlation with test results. The program results also indicate that in active gear 20 to 30 percent reduction in wing force relative to those occuring in passive gear.

As a result of measuring the bacterial contamination level of radiographic room, It was examined 27 of Gram (+) cocci, 1 of Gram (-) Bacillus was found in the air of a cubic meter (㎥) radiographic room. As a result of measuring the radiographic table, a large number of Gram (+) cocci was detected in the B, F and Gram (+) Bacillus was detected in the F, G hospital. as a result of measuring the radiographic cassette, a large number of Gram (+) cocci was detected in the B, G hospital and Gram (+) Bacillus was detected in the B, G and D, E hospital. After independent culturing and monitoring, it was clear up the D, E, F, G hospital Gram (+) cocci was the simple Gram (+) Bacillus. On the contrary, the D, G hospital appeared saprophytic Staphylococcus epidermis. This study verifies that a number of saprophytic bacteria can survive in the air of the radliographic room, radiogrphic table and radiograhic cassette. There was the hospital which is uncountable, and was very detected. These results notified all visiting person and patients could be infected from the baterial contamination in radiographic room. Also, it means that all visitors could be changed baterial transmitter. It is provides comfortable environment and better medical service to the disinfection that minor filming is indoor and personal hygiene in order to prevent this bacillary infection and must listen to the safe department of radiology on bacillary infection in ten thousand. This study verifies that common potentially pathogenic bacteria can survive in radiographic processing room. Therefore, effective cleaning regimens are of fundamental importance in controlling and preventing potential nosocomial transmission in the diagnostic imaging department
