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.

This study is aimed at giving the basic information for individual farm households to make decisions for optimizing their farm sizes and for the government to implement farm size optimization policies through the identification of combinations among rice production factors in plain areas like Cheolwon district and the suggestion of the optimal farm sizes of individual farmers based on the scale of economy calculated. The data of agricultural production costs of 50 rice farmers in the plain area which is located in Dongsong-eup Cholwon district, Kangwon province were used in the analysis. The 'translog' cost function among various methods which is a flexible function type was adopted to calculate the scale of economy in rice production. Seemingly unrelated regression(SUR) method was used in forecasting functions and processing other statistics by SHAZAM which is one of the computer aid program for quantitative econometric analysis. In conclusion, the long-run average cost(LAC) curve showed 'U-shape' which was different from 'L-type' one which was shown in the previous studies by others. The lowest point of the LAC was 9.764ha and the concerned production cost amounted to 633 Won/kg. Based on these results, it have to be suggested that around 10 ha of paddy is the target size for policy assistances to save costs under the present level of farming practices and technology. The above results show that the rice production costs could be saved up to 10ha in Cheolwon plain area which is a typical paddy field. However, land use, land condition, land ownership and manager's ability which may affect scale of economy should be considered. Furthermore, reasonable management will have to be realized by means of labor saving technology and cost saving management skill like enlargement of farm size of rice.

Congenital dermal sinus(CDS) is a rare entity widely known to occur as a result of the of the failure of the neuroectoderm to separate from the cutaneous ectoderm during the process of neurulation at the third to fifth week of gestation. The lesion can occur at any level of the craniospinal axis. but are located predominantly at the lumbosacral and occipital legion CDS of thoracic region and cervical region are rare The patient with CDS presents with meningitis and/or mass effect from the associated inclusion tumor They ars usually dermoid or epidermoid cyst. Teratoma is rarely associated with CDS. We report our experience of CDS in an 11-month old boy associated with an lntramedullary dermoid tumor at the thoracic region and together we report a review of the literature.

Sibjeondaebo-tang has been known to have an effect on remedy of anemia. The studies were carried out to evaluate the remedical effects of Sibjeondaebo-tang on the toxicity of lead-poisoned rats. The results obtained in the studies were as follows; 1. The body weight of Pb-treated group was decreased, while the group treated with Pb-SDT(Sibjeondaebo-tang) showed significant recovery of body weight. 2. The percentage of liver weight per body weight of Pb-treated group was increased remarkably, while the group treated with Pb+SDT showed slight increase compared with control group. 3. In hematological analysis, WBC was significantly increased in Pb-treated group, while the group treated with Pb+SDT showed nearly the same value as the initial.

Phosfon-D 및 CCC의 處理가 夏播양배추 育苗時의苗徒長抑制效果 및 收量에 미치는 影響

This experiment was carried out in order to study the effect of Phosfon-D and CCC on suppresive growth young cabbage seedlings sown in summer and on the yield after the transplantation in the field. The summer sown cabbage seedlings often cause unnecessary stem growth and this reduces the yield and produces an unsatisfactory marketable quality. Therefore, the availability of these chemicals in summer cultivated cabbages were investigated.

If a structure is built up on soft clay foundation, the time for constructing the structure should be shorten considerably and the consideration to the safety of the structure should be taken very carefully. Therefore, in order to meet the conditions specified in advance. Paper Drain pilot test construction results, one of the improvement methods of soft clay foundations, are analyzed and compared between an original design and a pilot test to testify the effect of the improvement methods applied for and then the monitoring results from the field tests are used for assuming the movements thats are to be or coming hereafter in soft clay foundation. The main results are summarized as follows : (1) According to the laboratory test results, the physical property of soil was presented to be stable since the natural water content ratio was reduced 47.6% and was under Liquid Limit. (2) After improving the soil foundation, the undrained shear strength was increased by about 3~4 t/m2. (3) According to the gradual analysis of settlement using hyperbolic method, the consolidation ratio did not reached to 90% when compared with the real data so it will be necessary to reduce the span of construction to paper drain.

This study analysed general behaviors of the lateral flow when unsymmetrical surcharge is worked on silt soils mixed with sand through model tests, and then investigated comparing with the existing suggestions. The critical surcharge, the point of time when lateral flow begins to occur was q_(cr),=0.40C_(u)-0.01 and the ultimate surcharge was q_(ult)=1.73C_(u)-0.10. The maximum lateral flow pressure was slightly lower theoretical value than that of the experiment value when the ultimate surcharge works, which indicates excessive consideration of safety rate. The formula of maximum lateral flow pressure of the silt soils mixed with sand was P_(max)=-5.27q_(ult)²+5.0q_(ult)+4 19. It occurred at 0.25H∼0.4H, which indicates that its occurrence depth was vertically distributed at 0.3H. The quadrilateral distribution where P_(0)=P_(max)/3 as the lateral flow pressure was applied bore a great resemblance to the distribution according to actual measurement. As the displacement obtained in the model tests was applied to the control diagram {Sv-(Ym/Sv)} presented by Matsuo·Kawamura, the result was that ; the destructive surcharge according to the standard of Matsuo·Kawamura showed a slightly lower value than the ultimate surcharge and the formula of settlement of the ultimate surcharge obtained in the three model tests was Sv=0.95exp{3.62(Ym/Sv)}.

안종필,박주원,류성기 朝鮮大學校 建設技術硏究所 2004 建設技術硏究 Vol.24 No.2

The construction of roads, bridges and buildings on the ground consisting of frail soft soil or organic soil as it may cause safety problems due to lack of supporting force and over-sinking. It is absolutely necessary to change the form of structures, to decrease internal force by consolidating the base sides of the structures, and to replace frail layers with good-quality materials for enhancement's sake. This paper is designed to make a comparative analysis of safety before and after sand drain methods and sand compaction pile methods were applied On the basis of the results of drilling surveys and indoor tests Sand drain construction methods are introduced to tackle 10-meter-deep frail layers. In case drain intervals are 2.0m ~ 3.5m wide when the construction method reaches 90% of consolidation degrees, 79 months ~ 74 months can be expected in terms of shortened time, respectively. If drain interval drops, the period when 90% of consolidation degrees are reached can be reduced by 2 percent. 2.7 meter-deep banking can be done on the raw soil in case the rate of standard safety against activity destruction stands at 1.25. However, in case four-stage banking is made, 6.8 meter-deep banking is made possible, and in case sand compaction pile construction methods are simultaneously used along with stage-based banking, the maximum baking can be 9.8 meters high ~ 9.0 meters high when drain intervals are 1.8 meters wide ~ 2.2 meters wide, respectively.
