본 저자들은 백혈병으로 진단 받지 않은 환자에서 경막외에 침범하여 척수를 누르고 있고 수술후 방사선 치료로 증상이 좋아진 과립구상 육종을 경험하였기에 이에 보고하는 바이다. Granulocytic sarcoma is an uncommon tumor composed of immature cells of the granulocytic series, occuring in patients with AML and blast crisis of CML. It may rarely precede an acute myelogenous leukemia with an uniformly fetal course. We experienced a case of granulocytic sarcoma of extradural space presenting as spinal cord compression in a 31 years old female with no evidence of leukemia on the bone marrow and periphera1 blood. The tumor was located to the T₁-T₃ having narrowing pole after decompression laminectomy, patient received local irradiation to the residual tumor bed, and being followed at the OPD without evidence of leukemia.

After full opening of distribution market in 1996, its competitiveness was lost and declined due to the emergence of a variety of distribution types, change of customers consumption habits, and purchase patterns. Therefore, Korean government began to support the modernization projects of traditional markets through the establishment of law for the activation of existing traditional markets. In this regard, this study attempts to diagnose the problems of facility modernization projects through substantial and concrete effect analysis on facility modernization projects to provide the activation methods effectively. To achieve this goal, we analyzed the overall satisfaction and substantial effect of facility modernization projects for traditional markes by carrying out questionnaire surveys on merchants at Jun-gang Yudeung Market in Jinju. As a result of questionnaire survey, customers were generally satisfied with the facility modernization project, the market environment was improved and the customer numbers and sales amount which show the actual improvement also increased after implementing the projects. Also, it was proved that customer numbers and the sales amount after the facility modernization project of traditional markets increased and the degree in the increase was low level of 5~20%. Therefore, it was analyzed that sub-project items of the facility modernization project, which have a significant effect on the activation of traditional markets, had a low level of influence.

In this study, software for testing technician qualification was analyzed in terms of satisfaction degree according to institutional types, gender and capability through the questions of QUIS using SPSS 7.5. And the results of free opinions were examined as well. The reliability of the survey showed Cronbach α=0.89. The overall satisfaction was analyzed with 59%. In the area of learning, the satisfaction was the highest. That means users felt relatively comfortable in learning. But the analysis also showed that the value of the system in the future was low, and the safety of the system was insecure. In conclusion, the revision of the function and the system was necessary

The purpose of the study designed a simulational instructioil mode1 for problem solving learning applying the situational simulation and process simulation to the technique for developing situational learning coursewares based on constructivism. The follow conclusions were obtained from the results of the study. First, there's require simulation model based constructivism instructional theory. Second, we first studied and analyzed characteristics of infants. Third, we established a learning model with which infants might effectively learn numerical concept and developed a courseware in the basis of it. Fourth, in this model, the learner can explore his own path for himself. Fifth, the numeric concept simulation model consists of one simulators, such as polygon classfication, comparison, seriation, a helping room. Sixth, simulation model should be designed to be self- directed learning. Finally, the simulators are designed for a learner to get experiences just like in a real world. The helping room provides the basic concepts needed for simulation.

The purpose of this study was to investigate the acute (4 hours) and repeated-dose (6 hours a day, 5 days a week, 4 weeks) toxic effects of I -hexene on Sprague- Dawley (SD) rats which were treated by inhalation. The results were as follows; I. The median lethal concentration (LC_(50)) was estimated 52,694 ppm (confidence limit 95%; 49,494~55,447 ppm) in acute inhalation. Abnormal clinical signs related to the l-Hexene were not observed with the acute inhalation dose. Gross findings of necropsy revealed on evidence of specific toxicity related to the 1-hexene, II. By repeated inhalation exposure the body weight of male were more or less reduced by the dose of 2,500 ppm and 5,000 ppm compared with control group. However there were no significant variation hematology and blood biochemistry for the exposed rats compared with the control rats. Abnormal clinical signs and gross findings of necropsy related to the 1-hexene were not shown. In conclusion when we exposed I-hexene to SD rats for 4 weeks, 5 days per week, 6 hours per day, the Lowest observed effect level (LOEL) was over 2,500 ppm and Non observed effect level (NOEL) was below 500 ppm.

The following is a retrospective study on the results of anterior spinal surgery with Kaneda Ⅱ instrumentation and Surgical Titanium MESH after thoracolumbar unstable spinal injuries. From July 1994 to June 1995, we operated on 14 patients at the Chosun University Kwang Yang hospital. Fourteen patients were followed for at least three months. Anterior spinal surgery was performed on the patients who had thoracolumbar unstable spine injuries. The procedure consisted of anterior decompression through corpectomy and stabilization with Kaneda Ⅱ instrumentation and Surgical Titanium MESH which was impacked with resected bone chip. Most of patients had demonstrated showed neurological improvement, relief of pain, immediate stabilization and early return to normal activities. Radiologic evaluation showed the correction of the fracture deformity with satisfactory outcome postoperatively.
