This is a retrospective analysis of 124 patients with uterine cervix cancer who were treated with postoperative radiation therapy after radical hysterectomy and lymph node dissection between May 1985 and May 1994 at the Department of Radiation Oncology, Soonchunhyang University Hospital. The results were as follows. 1. Overall and relapse free 5 year survival rate were 75.4% and 73.5%, respectively. 2. The numbers and sites of lymph node metastasis were prognostic factors by univariate analysis. Also the lymph node dissection numbers in patients with lymph node metastasis negative were prognostic factor. 3. Treatment related failures were 33 cases, the majority of them (23 patients) were in patients with lymph node metastasis. 4. To control recurrence for patients with high risk lymph node metastasis, postoperative radiotherapy is not sufficient. This result suggests that additional radiosensitizing agent or chemotherapy may be necessary for higher disease control. Also this study suggests the " through dissection of lymph node " in patients with uterine cervix cancer instead of " a few lymph node sampling ".

This study demonstrates that low processing rate for producing polyacrylonitrile (PAN)-based carbon fiber is a critical to obtain a homogeneous radial microstructure with high resistance to oxidation, thereby resulting in their improved mechanical strength. The dry-jet wet spun PAN organic fibers were processed (e.g., stabilized and then carbonized) utilizing two different rates; one is 1.6 times longer than the other. The effect of processing rate on the microstructural evolutions of carbon fibers was analyzed by scanning electron microscopy after slow etching in air, as well as Raman mapping after graphitization. The rapidly processed fiber exhibited the multilayered radial structure, which is caused by the radial direction stretching of the extrusion in the spinning. In case of the slowly processed fiber, the layered radial structure formed in the spinning process was changed into a more homogeneous radial microstructure. The slowly processed fibers showed higher oxidation resistance, higher mechanical properties, and higher crystallinity than the rapidly processed one. Raman mapping confirmed that the microstructure developed during spinning was sustained even though fiber was thermally treated up to 2800 °C.

This paper investigates the educational problems of junior college education linking industries and try to find the method for overcoming the limitations. Therefore, developing the related certificates upon ordering by industries will be a optimum option. Up to date, junior college education under educational-industrial cooperation is not distinguished curriculum from general vocational institute. This phenomenon incurred problems and limitations in developing human resources management fitting ordering education by industries. This study suggests 8 stages for the development of related certificates and provides model certificates which will apply every department. The best policy for a efficient human resources management toward junior college by educational-industrial cooperation will be opening special programs which will help students acquiring certificates.

Background and Objects : The purpose of this study was to determine the prognostic significance of estrogen receptor (ER) and progesterone receptor (PR) status and cyclin D1 overexpression in Korean women with early-onset breast cancer. Materials and Methods : Sixty women diagnosed and treated with breast cancer at the age of 45 or younger at Soonchunhyang University Hospital were entered for this study. The median age was 37years and follow-up periods were between 80 and 30 months. Paraffin embedded blocks of the primary tumor were processed for immunohistochemical staining of ER, PR and cyclin D1. Close follow-up data were entered in the database for analysis of the prognostic signifinance. Results : The proportion of the tumors staining positive for ER, PR and cyclin D1 were 45.7%, 44.1% 40.7%, respectively. No association was found between immunoreactivity of these markes and axiliary lymph node metastais. The expression of ER correlated with expression of PR and cyclin D1(p<0.001). Lymph node metastasis revealed a poor prognostic factor, but these 3 markers were not prognostic factors in these cohorts of patients, although trends toward poor outcome were observed among patients with negative staining. Conclusions : Cyclin D1 and steroid hormone receptor status were not significant prognostic factors in young women with breast cancer. Large-scaled studies are needed for evaluation of prognostic significance of these immunohistochemical markers in Korean women with early-onset breast cancer.

Objectives : This study is a random-controlled post-design for confirmation of headache degree, quality of life, and satisfaction to therapeutical effect on chronic headache adults after management of non-medicinal treatment (acupuncture therapy and stellate ganglion block therapy). Methods : 51 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified in to two groups, acupuncture group (AT group, n=28) and stellate ganglion block group (SGB group, n=23). Treatment was applied 2 times a weeks for 4 weeks. The effects of both groups were analyzed using VAS scores, BPI (Brief Pain Inventory) and the satisfaction degree to the therapy. Results : 1. The recognized score of the headache of AT group and SGB group was reduced indicating the degree of the headache was released. 2. The recognition at damage to the quality of life was reduced post therapy of AT group and SGB group, in which general activity, mood, enjoyment of life, personal relationship, and sleeping showed significant improvement of life quality. 3. The satisfaction degree to the therapy showed lower score than expectation to it in AT group and SGB group, however, it was not significant. Conclusions : The results showed that the four-week non-medicinal treatment (AT and SGB) in chronic headache patients was effective for reducing headache and releasing its damage in daily life, however, no difference in superiority was found. Therefore, non-medicinal treatment (AT therapy and SGB) could be utilized in chronic headache patients.

Subacute combined degeneration is a metabolic disorder of the spinal cord caused by vitamin B12 deficiency. A 72-year old man was admitted with weakness and tingling sensation of the bosh upper extremities. 9 years ago, he was diagnosed as having stomach cancer. So total gastrectomy with splenectomy was done at that time. The complete blood cell counts and morphology revealed megaloblastic anemia. Nerve conduction velocity study(NCV), electoromyography(EMG) and somatosensory evoked potentials(SEP) showed diffuse sensorimotor peripheral neuropathy. Magnetic resonance imaging(MRI) showed an increased T2-weighted signal, mild decreased T1-weighted signal, and slight contrast enhancement of the posterior columns of the cord in the cervical and upper thoracic spinal region. He was treated with vitamin B12 supplements and improved gradually. If abnormal sensation and muscle weakness was developed after gastrointestinal surgery, subacute combined degeneration should be considered in the differential diagnosis. We describe MRI findings of a typical case of subacute combined degeneration, which was induced by total gastrectomy.
