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.

A non-uniform finite-difference Thin Film Transistor Simulation Program (TFTSP) has been developed with very flexible and accurate physical model for hydrogenated amorphous silicon. In order to insure its usefulness and versatility as an analytic and design tool the code has been employed to compute the static terminal characteristics of a-Si:H TFTs under a wide range of bias conditions to allow the comparision of the model with experiment. On the basis of the usefulness of this computer model. TFTSP has been employed to analyze the source/drain contact behavior and/or other geometric factors of a-Si:H TFTs. The effects of the channel and overlap length on TFT performances have been analyzed to suggest the principles for the optimum transistor design.

林鍾弼,金勳 又石大學校 1993 論文集 Vol.15 No.-

"Juk Yom" was originated from Korean folk remedies with history of thousands of years. From the ancient days, people used parched salt by burning bamboo trunks stuffed with sea salt. This is a simple form of "Juk Yom" salt. Cinnarbar is a mineral composed of red mercuric sulfide after fire processing, which is used as tranquillizers by restraing excitation of the central nervous system. Juk Yom and cinnarbar were analysed by X-ray diffractor. The experimental results were summerized as followings; 1) In Juk Yom sample, the lattice parameter was in good agreement with that of J.C.P.D.S. card of sodium chloride. 2) In cinnarbar sample, the lattice parameter was in good agreement with that of J.C.P.D.S. card of mercuric sulfide. 3) The crystal structures of mineral drugs were not changed by fird processing.

Class V cavities, with their gingival margins located below cemento-enamel junction, were prepared on 90 healthy premolars that were extracted for orthodontic purpose; After 35% phosphoric acid etch and Scotchprep, Scotchbond 2 were applied, P-50 posterior composite resin were placed at all the cavities. The samples were divided into six groups and each group is consist of fifteen teeth. In experiment 1), control group with reisn filling only was compared to the experimental groups with additional application of bonding agent and sealant on composite resin surface. The experimental groups were thermocycled 55 times between 5℃ and 55℃. In experiment 2), the same procedure as in experiment 1) was carried out and the specimens were burshed 500 times under the load of 500g/㎠ with abrasion tester. All the specimens were,then,stained with basic fuschin solution,and microleakage was measured with steromicroscopy. The following results were obtained: 1.When the gingival margin of the cavity is placed on dentin or cementum, dye penetration was increased at the gingival margin after resin curing; brushing procedure showes this phenomenon. 2.Microleakage after the resin curing in the groups with additional application of bonding agent and sealant with thermocycling anly was more reduced significantly than control group'there was statistically significance(P<0.01). 3.There was no differance in reducing effect of microleakage between the bonding agent-applied group and sealant-applied group. 4.The experimental groups to which bonding agent and sealant were applied after thermocycling and burshing showed microleakage reducing effect and there was statistically significance (P<0.01) As a result, it can be concluded that microleakage at gingival margin,that was created after resin curing, can be significantly reduced by surperficial application and curing of bonding agent and sealant. Clinically, such utilization of bonding agent and sealant would be effective in prevention of secondary caries and pulp disease, which are the results of microleakage. Nevertheless, whether the microleakage reducing effect can last long under the abrasive action of burshing is still open to doubt, and there is a necessity for studing further.

김종진,장창엽,유완식,김언아,이정주,류정진,강필수,최종철,남용현,김윤삼 한국장애인고용촉진공단 고용개발원 2008 연구개발 Vol.- No.2

현행 우리나라 의무고용제도는 장애인구의 급격한 증가, 장애인차별금지 및 권리구제 등에 관한 법률의 도입 등 외부환경변화에 신축적으로 대처하지 못하고, 경증장애인 중심으로 의무고용제도가 운영됨으로써 중증장애인의 고용배제가 우려되고 있다. 본 보고서는 이러한 문제점을 해결하기 위해 의무고용제도의 일자리 확대와 고용증가를 통해 중증장애인의 고용기회를 확대할 수 있는 정책방안을 제시하기 위한 것이다. 본 보고서는 (1)의무고용 사업체의 의무고용 산정인원에서 자립장애인 제외 (2)현행 2% 의무고용률을 3%로 상향 조정 (3)사업체가 고용하는 중증장애인에 대한 더블카운트(2배) 가산제도 도입 (4)의무고용률 미달 사업주에 대한 부담금 차등징수의 4가지 정책방안, 제도 합리화 차원에서 장려금 지급방식의 개선과 사업주의 장애인에 대한 인식개선 방안을 제시하였다. 정책방안에 대한 영향분석 결과 의무고용 적용대상자에서 비장애인과 고용상 차별되지 않는 자립장애인(6등급)을 의무고용 산정인원에서 제외하는 경우 의무고용 사업체의 고용인원은 23,296명이 감소해 고용률은 1.35%에서 0.88%로 감소하였고, 의무고용 사업체의 장애인 일자리 수는 미고용인원의 증가로 15,152개가 증가하였다. 그리고 기금은 부담금이 631억원 증가하고, 장려금이 352억원 감소해 983억원의 수지개선 효과가 발생하는 것으로 나타났다. 의무고용 사업주의 의무고용률 3% 인상 방안은 의무고용률 상향 조정에 따른 미고용인원의 증가로 장애인의 일자리 수는 43,101개가 증가하고, 기금은 부담금이 1,709억원 증가하는 반면, 장려금은 293억원이 감소해 2,002억원의 수지개선 효과가 발생하는 것으로 나타났다. 의무고용 사업주가 고용하는 중증장애인을 2인으로 더블카운트 하는 중증장애인 가산제도의 도입은 의무고용 사업체의 장애인근로자가 67,261명에서 79,685명(1,2등급만 포함시 75,685명)으로 증가하여 고용률은 1.35%에서 1.60%(1.2등급만 포함시 1.52%)로 증가하고, 의무고용률 미달 사업체의 미고용 인원이 감소하여 2,745개의 일자리가 감소하였다. 그리고 기금은 부담금이 118억원 감소하는 반면, 장려금은 418억원이 증가해 536억원의 수지악화가 발생하는 것으로 나타났다. 의무고용률 미달 사업체의 고용유인을 위해 고용률 1.0%미만, 1.0-1.5%, 1.6-2.0% 미만에 대해 각각 20%, 10%, 5%의 할증률을 순차적으로 가중하여 부과하는 부담금 차등징수 방안(3차년까지의 효과임)은 1.0% 미만 사업주는 86만원, 1.0-1.5% 사업주는 64만원, 1.6-2.0% 미만 사업주는 58만원의 부담기초액을 부과할 때 고용률은 1.35%에서 1.53%로 증가(1.6-2.0% 미만 사업주는 의무고용률 2%를 달성)하고, 미고용인원의 감소로 장애인의 일자리는 8,836개가 감소하는 것으로 나타났다. 그리고 기금은 부담금이 58억원 감소하여 수지는 악화되었다. 이상의 네 가지 방안은 모두 장애인의 고용증대를 가져온다는 측면에서는 유효하지만, 장애인의 일자리 확대를 통한 중증장애인의 고용을 증대한다는 정책목표를 달성하는 데에는 한계점을 안고 있기 때문에 어느 한 정책만을 선택하기보다는 정책효과를 극대화하기 위해 정책결합(policy mix)을 이용하는 것이 바람직함을 제시해주었다. 즉, 의무고용 적용대상자 조정방안/의무고용률 상향조정 방안과 중증장애인 가산제도/부담금 차등징수 방안을 조합 또는 모두 동시에 선택하는 경우 의무고용 사업체의 장애인 일자리 수의 확대와 중증장애인 고용을 동시에 달성하고, 기금의 수지균형도 달성 가능한 것으로 나타났다. The mandatory employment quota system of Korea does not reflect the changing external factors such as the growing population of people with disabilities(PWDs) and the enactment of the Anti-discrimination Law for People with Disabilities. The current employment quota system focuses on people with mild disabilities thus excluding people with severe disabilities from employment. The purpose of this report is to propose a plan in order to increase employment opportunity for the severely disabled through the reform of the employment quota system. This report analyzes the following : (1) exclude grade 6 disability from mandatory employment quota (2) raise the employment quota from 2% to 3% (3) implement the double counting for employers that employ the severely disabled (4) differentiate the amount of levy collected from corporations that are unable to meet the quota. The aforementioned plans are useful in that they increase employment for people with disabilities. However, there are limitation to reaching the policy objectives by increasing jobs for people with severe disabilities. Therefore, to maximize the effects we should consider policy mix of these four policies. In other words, by mixing the policies of adjusting the employment quota target/raising the quota ratio and implementing the double count/differentiating the amount of levy, we can achieve the goal of increasing jobs for the severely disabled and maintain equilibrium between incomings and outcomings.

하천저질중 유기물에 의한 Methemoglobin생성능에 관한 연구

林鍾弼,金炳泳 又石大學校 1990 論文集 Vol.12 No.-

In order to investigate the pollution of the Chon-ju stream, the writer measured the methemoglobin formation ratio in the sediments of Chon-ju-stream running through Chon-ju city in May, July and September in 1989. The results were as follows: 1. The amount of extracts by the organic solvent appears to be increased in proportion to the direct pollution level of water. 2. Especially, the methemoglobin-Formation ability of the organic exracts of the contaminated sediments of the river was remarkable, and that of the non-comtaminated sediments of the river was capable of recognition. 3. The amount of the organic extracts of the river sediments was related to season. because it is considered that the rain occasionally sweeps and precipitates the sediments of the river.

國內 建設監理事業者의 選定方式에 관한 硏究

안종필,최병식 朝鮮大學校 建設技術硏究所 2000 建設技術硏究 Vol.20 No.1

Recently, the order methods in construction are getting diversified and new innovations are being made in the area of construction management and project management. These changes have stimulated a line of studies on the management system in construction work and related laws and regulations. These studies are very valuable in that they portrait the current level of technology in construction and provide a chance to improve the technology. The workers employed in the construction sector constitute 13% of the total labor force, and the production in the sector 17% of GDP. But, the level of construction technology comes to only 67% of that of developed countries. The reason the construction technology in Korea stays backward is because the legal and institutional systems in Korea fails to effectively support the technological development of established construction companies. This gap in construction technology is even larger in the field of construction supervision, which is a relatively young area in Korea.
