The major forms of amyloidosis affecting the eye are primary systemic and localized amyloidosis. Primary Amyloidosis localized to the conjuctiva is relatively rare, especially involved to bulbar conjunctiva and corn eo scleral limbus and is consiccered to be in the differential diagnosis of other conjunctival diseases. We diagnosed a amyloidosis in which the biopsy from the superior bulbar conjunctiva and superior cornea of the left eye of 68-year-old woman showed histopathologic findings of amyloidosis. There were no evidences of amyloid deposit except conJuntiva and cornea on physical and other systemic examination, including immunelectrophoresis, and cornea on physical and other systemic examination, including immunelectrophoresis, and no evidences of underlying disease that can cause amyloidosis. So we concluded that it was primary localized amyloidosis of bulbar conjunctiva and cotnea.

4.A Simulation Model of a Outpatient Scheduling System.

Korean Journal of Preventive Medicine 1986;19(1):56-64
This paper describes a GPSS-based, multi-server queueing model that was developed to simulate the patient flow, and to analyze the effectiveness of the patient scheduling system under various conditions. Unpredictable and unacceptably long waits to receive the service at the outpatient department of a general hospital necessitated the study. Arrival and service time distribution needed for the simulation model were generated from actual arrival and service patterns observed during the peak hours. The simulation results show that a change in patient scheduling system (i.e. time interval between appointments, starting time, and the number of physicians) from a current system would significantly reduce the patient wait time. This study provides the hospital administrator with an analysis of patient scheduling system under several conditions, and will be used to plan future scheduling system and staffing. Studies such as this can demonstrate the value of simulation in providing information for use in future planning.

OBJECTIVES: To explore the role of apolipoprotein E in schizophrenia, we investigated apoli-poprotein E polymorphism in groups of patients with schizophrenia and normal controls. We also examined the relationship of clinical characteristics of schizophrenia to apolipoprotein E genotypes. METHODS: Samples were obtained from 101 schizophrenic patients and 96 controls in Korea and apolipoprotein E polymorphisms were analysed using polymerase chain reaction. RESULTS: The genotype and allele frequencies did not differ from those of controls. The clinical variables of schizophrenia, such as positive and negative groups by PANSS, subtypes by DSM-IV, family history were not associated with each genotypes. CONCLUSION: We could not find the association of apolipoprotein E in Korean schizophrenic patients and it could be suggested that apolipoprotein E isoforms might not play a main role in expression of schizophrenia.

Spindle cell lipoma was first described in 1975 by Enzinger and Harvey as a variant of lipomas. Histopathological findings show the lipomatous tissue to be replaced by a mixture of uniform spindle cells and mature fat cells closely associated with a mucoid matrix and a varying number of collagen fibers. Immunohistochemical staining is reported to give assistance in the differential diagnosis af spindle cell lipoma from other fibrous or neural tumors. Also, it can be used to investigate the origin of the spindle cells. We report a case of spindle cell lipoma in a 41-year-old female. She had a solitary, normal skin colored, bean sized, subcutaneous mass on the forearm. Most of the spindle cells were strongly positive for vimentin, CD34 and NSE, but negative for actin, factor VIII, S-100 protein and neuro- filaments. The tumor was excised. No recurrence was recognized in a 10 month follow up period.

For the evaluation of the 51Cr labelled in-vivo crossmatching test as a transfusion safety test, We examined the viability of the thransfused autologous and heterologous 51Cr labelled red cell at 1 hour and 24 hour in 6 normal volunteers and 4 patients whose RBC had been stored in CPDA-1 media from 1 day to 30 day. In both autologous transfusion control group(n=3) and allogeneic transfusion control group(n=3), the in-vivo RBC survival rate were more than 70% at 1 hour and 24 hour compared to that of basal 3 minute result(percent counted as 100%), and the eluted free radioisotope activity was less than 5% compared to that of whole blood. The crossmatch incompatible patient group also satisfied the safe transfusion criteria. The mean labelling efficiency which was tested in three patients was more than 95% and also satisfactory to reliable test. We concluded that in-vivo crossmatching test using 51Cr radioisotope would give us valuable informations about transfusion safety, especially in serologically incompatible patients.

Steroid cell tumor of ovary, first described as lipid cell tumor, is rare lesions composed entirely of cells resembling typical steroid hormone - secreting cells, that is lutein cells, Leydig cells, and adrenal cortical cells. Steroid cell tumors oftcn secret androgen and manifest themselves with symptoms of virilization. Other presentations include abdominal swelling or pain, menstrual dysfunction, postmenopausal bleeding, or rarely ascites. We experienced a case of right ovarian steroid cell tumor, not otherwise specified(NOS), manifested hirsuitism and amenorrhea in 49 - year - old patient. The tumor was about 5 cm in size, and associated with huge ascites (l3,000 ml), both pleural effusion, and elevated serum CA 125. We present a case of Meigs syndrome associated with benign ovarian steroid cell tumor with a brief review of the literature.

10.An Analysis of Course Evaluation Programs at Korean Medical Schools.
Korean Journal of Medical Education 2007;19(2):133-142
PURPOSE: Following the first in 1990, the use of course evaluations(CE) by medical schools across the Republic of Korea has grown steadily since 1997. The purpose of this study was to investigate these CE programs and to make general recommendations for further implementation. METHODS: A questionnaire survey was conducted by mail. From June 20 to September 22, 2006, data was obtained from 38 of the 41(93%) medical schools in the country. Of those who responded, 27 schools also sent their CE forms as requested. RESULTS: There was little difference among the 38 medical schools in the main body, methods, frequency, grades, systems of evaluation, and types of survey. Evaluation criteria such as instructor effectiveness, course management efficiency, and student satisfaction showed high frequency, whereas issues concerning learning objectives and workload were less common. In contrast, the stated purposes of employing CE varied from school to school. While 92% of the respondents regarded improvement to the quality of instruction as the goal of their programs, 32% indicated that CE results also factored in administrative decisions concerning promotion, tenure, and salary increases. CONCLUSION: In addition to embracing the expanding role and influence of CE in Korean medical education, schools must proactively enact measures to enhance further implementation. First, evaluation criteria should be better formulated to increase the consistency, reliability, and validity of CE results. Next, to promote efficiency, the scheduling and methodology of CE administration should carefully consider the medical curriculum. Finally, professional attitudes should be fostered to recognize the value of CE as a tool for raising educational standards overall.
