The Comprehensive Examination for the undergraduate students is planned to adopt the Jeonbug National University for the purpose of enhancing the quality of its educational outputs. In order to effectively measure and evaluate the level of student progress toward the minimun standard as the students who have finished their general education and basic education for their major field study, the university has decided to make an item pool related to the subjects for the examination. This study is an attempt to make good items of five required courses among general education subjects which are Korean Language, English, Korean History, National Ethics. and Natural Science and are expected to be the subjects of the examination. Instead of making those items separately from the regular examination during the academic semesters, the university plans to collect and use good items from the usual mid-term and final examinations of those subjects. A key concern, in this study, therefore, is to analyze all the items used for the mid-term and final examinations of those subjects during the regular academic semesters. From the data of an about 100 sample in each subject at each time of total three tests, the difficulty index, discrimination index, the response rate of students on each item, and other general descriptive statistics are calculated and then good items are pooled for the future use for the Comprehensive Examination. Anhother important concern in this study is this study is given to the collection and analysis of controversial issues and problems on the process of operating the examination at other universities where the Comprehensive Examination is already adopted. The data from four institutions and from opinions of six participants of this study are used. The following main findidings are summarized : 1. The items have generally shown to be easy while the degree of discrimination is low. 2. Among the five subjects, Korean Language shows the highest rate of right answer (difficulty index) while English the strongest one in the discrimination index. 3. When comparing two types of test between the multiple choice and the short-answer, the latter seems to be powerful in both difficulty and discriminative. 4. The only one question of essay type test reveals clear limitations in scoring and evaluating students progress. 5. All items are constructed under the consideration of content-referenced base, not of the basis on behavioral aspect. 6. The analysis of issues and problems related to the Comprehensive Examination suggests that it is acceptable to test in terms of required subjects of general education and a few most basic subjects of major areas of study. 7. The examination can be functionally operated when it is held at the end of the first year of and before the beginning of the second year of the college years. The length of the examination is usally held from three to five hours. 8. Since the examination should be existed on the idea of criterion-referenced base rather than of norm-referenced one because of its testing the qualification of the entering behavior of students for the further study in their major field, the standard of the pass-and-failure should be set on at least 60 percent of correct answers in each subject. But there must be provided at least two additional opportunities for the make-up examination for those who failed in the first one. 9. A special committee must be established in order to deal with all the details related to the Comprehensive Examination.

Multiple myeloma is a disease caused by neoplastic plasma cells that synthesize abnormal amouts of immunoglobulin or immunoglobulin fragments. Light chain myeloma are regarded as a separate category characterized by a more malignant clinical course. Light chain myelomas are said to grow fastest of all and are associated with more osteolytic lesions, more hypercalcemia, and a higher incidence of renal failure and amyloidsis than either the IgG, IgA varienties The authors experienced a case of patients with λ-light chain myeloma. A 43-year-old male patient admitted to our hospital with the chief complaint of both rib and lower back pain. The radiologic findings showed multiple pathologic fracture in ribs. osteolytic lesions in 2nd, 3rd cervical spineimmuture plasma cells. Serum electrophoresis showed normal finding. Urine electrophoresis evealed an M-spike. Urine immunoelectrophoress demonstrated λ-monoclonal protein. With the cycle of melphalan, prednisone and α-interferon chemotherapy improved of pain was observed. So we reported the case with brief review of previous literature.

李鎭春,鄭忠泳 慶北大學校 産業開發硏究所 1983 硏究報告 Vol.11 No.-

The purpose of this study is to analyze the managerial situation and to understand the administrative level of fiber & textile companies, especially chemical textile firms located at Taegu area. Simultaneously pointing out managerial problems and operational difficulties, this paper looks for a reform measure for them and examines their growth-potentials. For the sake of analysis, this study uses a case study of "A" company as its methodology. The analysis finds out the deficiency on present Income Sheet. Moreover many managerial problems are found. From the managerial rationalization point of view, it is required to adapt the cost control system and the independent profit system in order to solve the present difficulties. In addition, this paper concludes that regional chemical textile firms have many problems and difficulties in light of the "A" firm case. Therefore someone has asserted coming-declining-stage of textile industry. But a rational solution of those problems can provide much growth-potential for the regional chemical textile firms.

박근호,유형륜,정영진,윤기중,한원철,유대열,문형배 圓光大學校 醫科學硏究所 1999 圓光醫科學 Vol.15 No.2

Background: Thioredoxin peroxidase(TPX) is a kind of recently discovered antioxidant enzyme which react as rapid hydrogen ion donor for the removal of hydroperoxide. The action and distribution of the TPX was poorly understood in the human diseases. This experiments were designed for the study about the distribution of the TPX in the chronic granulomatous inflammation and about the correlation between the expression of TPX and the site of inflammation, histological activities of tuberculous inflammation or existence of mycobacterium in the inflammatory foci. Methods: The immunohistochemical stains were performed for the localization of the TPX-2 in the epithelioid cells, giant cells and lymphocytes in the chronic granulomatous inflammation. The tissue sections were obtained from the paraffin blocks of the 54 cases of tuberculosis (lung 21 cases, lymph node 12 cases, bone and soft tissue 12 cases, kidney 9 cases; active 33 cases, inactive 21 cases by the histologic classification; presence of mycobacterium 15 cases, no mycobacterium 39 cases by PCR reaction). Results: The expression of TPX-2 was 16.7% in the giant cells, 27.8% in the epithelioid cells and 100% in the lymphocytes of tuberculous inflammations. The expression of TPX-2 in the giant cells and epithelioid cells of the tuberculosis were 28.6% and 57.1% of the pulmonary tuberculosis; 33.3% in each cells of the renal tuberculosis; 0% in each cells of the lymph node or bone and soft tissue tuberculosis. The expression of TPX-2 in the giant cells and epithelioid cells were 9.1% in each cells of the active tuberculosis and were 28.6% and 57.1% in each cells of the inactive tuberculosis by histologic classification. The expression of TPX-2 in the giant cells and epithelioid cells was 40% in each cells of tuberculosis which mycobacteria were detected and the expression of TPX-2 was 7.7% and 23.1% in each cells which mycobacteria were not detected by PCR reaction in the paraffin embedded tissue. Conclusions: The above results were summarized that the TPX-2 in the giant cells and epithelioid cells were more frequently expressed in the inactive tuberculosis than in the active tuberculosis. These results suggest that the TPX-2 is a kind of regulating or suppressing factors in the activity of the tuberculosis.
