BACKGROUND AND OBJECTIVES: Computed tomography of the temporal bone can provide otologists precise informations regarding the middle ear diseases. In this study, we aimed to measure the distance of mastoid antrum using the temporal bone CT for predicting the distance of mastoid depth during the mastoid surgery. MAERIALS AND METHODS: We analyzed normal ears of 88 patients who visited the Department of Otolaryngology, Chonnam University Hospital during the period between Aug. 1996 and Aug. 1997. These patients demonstrated unilateral chronic otitis media, temporal bone fracture, and traumatic facial nerve palsy. RESULTS: The mean distance of mastoid antrum was 11.45mm. The distance of mastoid antrum according to age distribution showed 7.75 mm in 0-4 year old group, 10.35 mm in 5-9 year old group, 10.71 mm in 10-14 year old group, 11.50 mm in 15-19 year old group, and 11.93 mm in over 20 year old group. The distance also differed between males and females, with 2.84 mm for male and 11.24 mm for female. CONCLUSION: For the group under 20 years old, the distance of mastoid antrum increased as the patient's age became older. Especially, the group who were between 5 to 9 years old showed marked increase in the distance, and the distance did not differ between male and female. The distance of the mastoid antrum of the Korean adults was 10.1-13.7 mm and it represents some difference when compared with that of Westerners.

PURPOSE: This paper aims at reporting and examining the experiences of medical ethics education with case-based learning and large-group discussion. METHODS: The subjects were a group of 100 students in the third year medical student. The medical ethics course was designed to minimize unidirectional lectures and to maximize interactive work with a large group at the classroom utilizing cases as teaching material. In the middle of the course, all students were divided into small group of 4~5 members. Each group was to find and, based upon group discussion, analyze each different case containing ethical dilemma, and present it as a midterm report. To examine the effectiveness of case based learning in medical ethics education in a large classroom, the authors analyze the students' feedback and evaluation delivered in survey questionnaires from 94 out of 96 students. RESULTS: Students' feedback showed that small-group discussion, interactive work in a classroom, and case-based studies were effective as well as practicable for medical ethics education for a large group.

The incidence of lung cancer and its mortality rate are increasing in Korea. At the time of diagnosis, 40% patients of lung cancer patients had metastatic lesions. The common metastatic sites are the contralateral lung, bone, liver, adrenal gland and the brain. Metastasis to oral mucosa is rarely encountered in lung cancer and metastasis to the gingiva is more uncommon. Approximately 1% of malignant carcinomas in the oral cavity are the result of metastases, and 10-25% of metastatic cancers originate from lung cancer. Clinically metastatic gingival lesions are benign including hemangioma, pyogenic granuloma, giant-cell granuloma or a peripheral fibroma. Often metastases to the gingiva are diagnosed too late and by the time they are detected, they have metastases to other organs. Here we report a case of small cell lung carcinoma that had metastased to the gingiva with review of relevant literature.

Sustemic arterialization of the lung without sequestration is the rarest from of congenital anomalous systemic arterial supply to the lung, where an anomalous systemic artery arising from aorta supplies a normal unsequestrated segment of the lung. The non-sequestrated lung parenchyma which is supplied by an aberrant artery, has no parenchyma or bronchial abnormalities, and there is a normal connection with the bronchial trees. The symptoms of this disease varies. In most patients, it is often asymptomatic, but symptoms including dyspnea, hemoptysis, and central nervous system complications are possible. Here, we report a case of systemic arterialization of the lung without sequestration, which confirmed by angiography, with a review of the literature.

PURPOSE: This paper reports on the development a program to foster 'good doctors' who care for their patients with humanism and self-directed learning ability. METHODS: In order to develop the program, Korea University College of Medicine established educational committees. In collaboration, these committees discussed the direction for curriculum reorganization, performed a needs analysis of specified programs, and built realistic strategies for program management. Based upon the needs analyses, through literature review and survey studies, committee discussions and benchmarking of other medical schools, three programs were developed for rearing humanism and self-directed learning ability in medical students were developed: Service learning by experiential learning; Doctoring by small group activities; and Communication skills program by various small group activities. RESULTS: The evaluation by the pre-medical students who participated in the service learning program for one week reveals that through service learning, pre-medical students had an opportunity to obtain the attitudes that encompass the sanctity and dignity of human life and an understanding of cultural, social and religious customs and beliefs that differ from his or her own. In addition, the pre-medical students came to realize that patients' most difficult problems might be caused by non-medical factors as well as medical factors. CONCLUSION: It is needed to grope for the way that leads the active participation of students in the continuous linkage of substantial post-work evaluation and next learning of volunteering in order to make the program of educating the public spirit more than self-learning of experience.
