It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

오늘날 현저한 CO2 레이저의 응용 추세에 발맞추어 보다 다양한 형태의 출력 제어 기술이 대두되고 있다. 본연구에서는multi-Pulse Superposing-Discharge 기술을 이용하여 다양한형태의 CO2 레이저의 펄스를 성형 하였다. 펄스 성형을 위한 방법으로 PIC one-chip microprocessor를 이용하여 삼중 PFN 모률의 SCR을 각각 고유의 지연시간을 가지도록 제어하였다. 실험에 사용된 삼중 PFN 모률의 전원 회로는 각각 캐패시터 인덕터,SCR,고압 펄스 트랜스 그리고 고압 트랜스 2차측에 브릿지 정류기로 구성 하였다. 고압 펼스 트랜스의 1차측을 제어하므로서 PFN 모률의 동작을 저 전압에서 수행 할 수 있다. 트랜스의 2차측에 연결된 전파 정류기는 펄스 에너지를 부하에 지속적으로 전달한다. 본 연구에서는 삼중 PFN 모률의 각각의 SCR을 다른 시간 가격을 두고 트리거 하므로서 다양한 Long pulse shaping을 실현하였다. 또한 약 250-1000μs 의 주기를 가지는 다양한 펄스형 레이저 빔을 얻었다.

인구재분배(Population Redistribution) 정책에 대하여

권태환(Kwon Tae Whan),Yoon Jong Ju(토론자),Kim Sun Oong(토론자) 한국인구학회 1979 한국인구학 Vol.2 No.1

The population redistribution policy of Korea may be summarized as follows: 1. Decentralization of industries. 2. Construction of new towns including development of temporary administrative city. 3. Development of growth poles. 1. The decentralization of industries as a means of population dispersion has been widely debated and proven to be effective in many other countries. As pointed out before, the decentralization of industries has a widely varying degree of impacts on population dispersion according to the nature of industrial re-location programs. 2. The construction of new towns and the development of administrative cities have proven to be effective as a population redistribution policy in socialist countries and Japan. These example do not guarantee success if such policy is applied in Korea. The success depends on the amount of the concomitant investment to be made in educational and cultural facilities in the new towns. 3. The development of growth poles as a means of population dispersion has not proved to be successful in the Eastern Block Countries and Japan. However, this may be the optimal means of dispersion population for Korea when one considers her present level of economic development. (1) The development of farming sector and (2) the slow-down of farming population exodus into cities should be considered as a viable alternative program for population dispersion policy. We cannot cite many examples in other countries where the development and improvement of farming sector has been successful as a means of dispersing population. However, Japan's development of her northern areas has not only improved the standard of living in Hokkaido but also contributed to population dispersion. Discussant Yoon, Jong Ju: Population movements in Korea have resulted in the concentration of people in cities and the reduction of farming households. In the Sixties, the population of the nation converged into Seoul. As a result, the population dispersion policy emphasized the "slowing-down" of the population movements in to Seoul. This policy has shown some success in that the rate of population growth in Seoul has decreased since 1970 and the more so since 1975. This phenomenon, however, is confined to the city of Seoul. The surrounding areas have shown an increasing rate of population growth. The above indicates that population policy and population dispersion program should be conducted with long-range planning, if they were to be successful. However, such has not been the case. It should also be pointed out that population policy should be a comprepensive program encompassing population, economic and social aspects. Korean population policy has not been such comprehensive program. The population policy in the Eighties should not confine itself in decreasing the rate of population growth. Instead, it should focus on improving the quality of population and thereby, increasing the manpower of high quality. In order to carry out such policy, investment should be made to improve the data on population, in particular, on children. Discussant Kim, Sun Dong: Korean population policy does not possess foresight and is segmented without a clearly formulated long range goal. One inevitable and undeniable fact appears to be that three quarters of the nation's population will eventually settle in urban cities. There are many problems associated with the population concentration in the urban areas. First, there exist the well-known problems of environments and traffic congestions in urban centers. Second, there are the problems associated with the effective utilization of the nation's land and natural resources. Third, there are the geopolitical issues related to the national defense and security. Although we recognize these problems, it should be also pointed out that population concentration in cities is an inevitable result and cause of economic development.<

연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

주혜련,박종호 이화여자대학교 사범대학 교과교육연구소 2013 교과교육학연구 Vol.17 No.4

This study attempted to demonstrate the effect of Response to Intervention(RTI) as a teaching methodology for underachievers in science. The participants were fifth-grade students, and the intervention program involved the science textbook section 'The speed of an object'. In the first stage of the intervention, the subject matter was taught generally over a period of three weeks. The researcher conducted subgroup teaching using the direct method of teaching in the second stage of the intervention for eight weeks. This study consisted of three stages: the first stage of the intervention involved selecting underachievers in science and determining their baseline(the bottom 15%), the second provided sixteen thirty-minute sessions, twice a week over eight weeks. In the first stage of the RTI program, the researcher selected eleven underachievers in a fifth-grade science class for an experimental group. In the second stage, interventions were provided to them based on the Direct Instruction(DI) method. During the interventions, three achievement tests and ten curriculum-based assessments were conducted. The major research findings were as follows: first, the interventions based on the DI approach had positive effects on the underachievers. The science underachievers showed a higher achievement level than the general students when a sincere attitude was indicated. Second, the RTI program had positive effects on some of the science underachievers; although three of the eleven participants in the second stage showed no significant change. Third, this study suggests that underachieving in mathematics and science is closely related; science underachievers in the second stage were all underachievers in mathematics, too. RTI has not been applied to mathematics classes; but, based on the results of this study. RTI in science classes should be actively carried out in the future; it could contribute to the relief and determination of science underachievers. 현대 과학교육은 ‘모든 이를 위한 과학’을 지향하고 있다. 과학적 인재를 양성하는데 주력하는 것이 아니라 모든 이에게 과학적 소양을 함양시킬 수 있는 과학교육에 집중하는 것이다. 초등교육은 더욱 그러하다. 이에 본 연구는 중재 반응(Response to Intervention, RTI)을 적용하여 과학 학습부진 아동을지도하여 구제하는 데 효과가 있는지 입증하기 위해 실시되었다. 초등학교 5학년 아동을 대상으로 하였으며 5학년 2학기 3단원 ‘물체의 속력’단원으로 중재 프로그램을 구성하였다. 중재 1단계에서는 3주에 걸쳐 과학 전담 교사가 일반 교수를 실시하였고, 중재 2단계는 8주간연구자가 직접 교수법을 활용한 소집단 교수를 실시하였다. 1단계에서 학업성취도 검사 2회, 교육과정 중심 평가는 4회를 실시하여 두 검사 점수의 합이 하위 15%를 나타내는 15명을 과학 학습부진 아동으로 선별하여 그중 본인의 동의를 얻은 11명을 2단계 연구를 실시하였고, 2단계에서는 총3회의 학업성취도 검사와 총 10회의 교육과정 중심 평가를 실시하여 중재 반응의 효과를 분석하였다. 그 결과 2단계 중재로 과학 학습부진 아동으로 선별된 11명의 아동 중 8명이 일반 아동을 뛰어넘은 점수를 획득하였다. 따라서 과학 학습부진 아동이라 할지라도 중재 반응의 2단계소집단 교수에 성실히 임한 부진 아동은 일반 아동과 같은 학업성취도를 보일 수 있음을 확인하였고, 구제되지 못한 나머지 3명의 아동은 동일한 시간 동안 동일한 중재를 적용했음에도 불구하고 반응하지 않았으므로 과학 학습부진 아동이라고 판별할 수 있었다. 또한 2단계에서 반응을 보이지 않아 과학 학습부진 아동으로 판별된 아동이 모두 수학기초 학습 부진이었던 것으로 나타나 수학기초 학습 부진과 과학 학습 부진은 관련성을 가지고 있음을 볼 수 있었다. 이러한 연구결과를 바탕으로 이제껏 수학에서만 다루어지던 틀을 깨고 앞으로는 과학에서도 중재 반응을 적용한 중재 프로그램을 통하여 과학 학습부진 아동의 구제와 판별에 기여할 것으로 보인다.

입체도형학습에 있어서 컴퓨터와 웹을 활용한 학습은 학습자에게 공간개념과 입체도형을 이해하는데 많은 도움을 준다. 지금까지 업체도형학습을 위한 여러 연구에서는 3차원 가상공간을 효과적으로 표현하지 못하고 학습관련 기능이 제한되어 있다. 이 연구에서는 3차원 가상공간을 효과적으로 표현할 수 있는 JAVA 3D를 이용하여, 웹상에서 학습자가 입체도형을 생성하고 학습에 관련된 다양한 조작을 할 수 있는 입체도형학습 프로그램을 개발하였다. 본 프로그램을 이용하여 학습자는 입체도형개념과 공간개념을 효과적으로 이해할 수 있으며, 입체도형 학습에 있어서 자기주도학습이 가능하다. In the geometric solids study, applying computer and web is very helpful for leamers to understand the concept of 3D space and geometric solids. There are many trials for the geometric solids study in previous researches, however the 3D virtual reality cyberspace was not effectively expressed and limited functions were available. Thus, in this study, we developed very useful program which learners create and operate the geometric solids in cyberspace with JAVA 3D. JAVA 3D can express 3D virtual reality cyberspace very effectively. By using the program, leaners can understand the geometric solids theory and the formulation of space concept effectively. Also it motivates learners to understand geometric solids study and enables Self-Directed-Learning.

The cement-based system among S/S(Solidification/Stabilization) is widely used to treat hazardous wastes. In this study, tannery sludge was solidified to evaluate the stabilization effects of using admixtures in the cement-based S/S. Fly ash as substitute also used to increase the strength of the S/S of hazardous waste. The compressive strength measurement and leaching experiment of chromium metal of solidified mortar were carried out to compare and evaluate the physical and chemical characteristics of solidified hazardous waste sludge. From the result of this study, there was increased of compressive strength by using AEW-3(early-hardening AE water reducing agent), and leaching concentration of chromium became low enough to satisfy the regulatory criteria. The successful solidification for the organic contaminant and heavy metal in hazardous waste should enable to treat by cement-based system using early-hardening AE water reducing admixture and fly ash as substituted cement.
