Advances in Information Technology and in Biomedicine have created new uses for CAD technology with many novel and important biomedical applications. Such applications can be found, for example, in the design and modeling of orthopedics, medical implants, and tissue modeling in which CAD can be used to describe the morphology, heterogeneity, and organizational structure of tissue and anatomy. CAD has also played an important role in computer-aided tissue engineering for biomimetic design, analysis, simulation and freeform fabrication of tissue scaffolds and substitutes. And all the applications require precision geometry of the organs or bones of each patient. But the geometry information currently used is polygon model with none solid geometry and is so rough that it cannot be utilized for accurate analysis, simulation and fabrication. Therefore a case study is performed to deduce a transformation method to build free form surface from a rough polygon data or medical images currently used in the application. This paper describes the transformation procedure in detail and the considerations for accurate organ modeling are discussed.

A 8 year old male was admitted to the Department of Thoracic Surgery, Korea University Hospital on June 22, 1978. The chief complaints were cyanosis and exertional dyspnea since at birth. EKG shows BVH and dextrocardia, phonocardiogram revealed the accentuation of second heart sound in aortic area. Echocardiogram from the left ventricle to the base of the heart, there is a discontinuity between the ventricular septum and the anterior aortic margin with a large aortic root & aortic overriding. His cardiac catheterization data and cardiac angiogram shows situs inversus totalis, dextrocardia, right aortic arch, large ventricular septal defect etc., and finally diagnosed Truncus Arteriosus. Edwards type IV with retrograde aortogram and selective bronchial angiogram. This is the first operative case reported as Rastelli operation for Truncus Arteriosus type IV in the literatures in Korea. Authors have experienced I case of Truncus Arteriosus, Edward type IV and Rastelli operation with Dacron Arterial Conduit Graft under cardiopulmonary bypass on July 3, 1978. The procedures were as follows; 2] Cardiopulmonary bypass: Origin of bronchial arteries excised from descending aorta bilaterally; defects in aorta closed. 2] Horizontal incision made high in right ventricle. 2] Ventricular septal defect [Kirklin type I+II] closed with Teflon patch. 4] Bifurcated dacron arterial graft with pericardial monocusp sutured to the bilateral pulmonary arteries. [Diameter 9 mm: Length 7 cm]. 5] Proximal end of the conduit graft anastomosed to right ventricle. [Diameter 19 mm: Length 5 cm]..Total perfusion time was 220 min. The result of operation was poor due to anastomotic leakage and increased pulmonary vascular resistance resulting acute right heart failure. The patient was died on the operation table. Literatures were briefly reviewed.

This study was carried out to see dietary intakes of patients with coronary heart disease since we don't understand their dietary patterns even though the mortality and prevalence rate of coronary hear disease are increasing in this country. We studied 75 coronary heart disease patients and 150 randomly selected controls, matched for age, sex, height and weight, in a population based study. All subjects completed a questionnaire that included disease history, diagnosis time, current treatment, etc., a 24 hour dietary recall, and measurement of height and weight. Compared to controls, patients had less likely to drink alcohol and smoke cigarette (p＜0.05). The energy intake of patients was significantly lower than that of controls, but the intakes of fiber, $\beta$-carotene, sodium, folate, vitamin C, potassium in male patients and those of vitamin C and sodium in female patients were significantly higher than those of controls (p＜0.05). Mean adequacy ratio and dietary variety score of patients were also higher than those of controls (p＜0.05). Patient group's consumed less cereals than controls, but more vegetables, milk products, and nuts in male patients and fruits, beans and seasonings in female patients compared to controls'. There were not significant differences of lipid compositions between two groups, except linolenic acid. These data suggest that patients with coronary heart disease in Korea had better dietary nutrient intakes compared to healthy controls, which might be helpful to prevent recurrence of coronary heart disease.

This study examined the effects of the Ministry-of-Health-and-Welfare-initiated comprehensive nursing service on the nursing performance, job satisfaction, and customer orientation among nurses. The participants were nurses working in a running hospital without a patient-sitter in S city (Experimental group=57, Control group=55). The data was collected at 1 and 6 months following a pilot program and analyzed by SPSS using a Chi-squire test, t-test, Kolmogorov-Smirnov test and ANCOVA. The experimental group showed significantly better nursing performance, job satisfaction, and customer orientation than the control group. This finding can be used to establish the criteria for systematizing comprehensive nursing service.

Objective: We present a case of chemotherapy-induced neuropathic pain with the aim of driving further study evaluating the effectiveness of Oriental medical treatment on patients with neuropathic pain. Method: We prescribed Bogijetong-tang (BJT) two times a day and performed acupuncture and moxibustion once a day over one month of hospitalization. Laboratory tests were performed twice a month during this period. To evaluate the therapeutic effect, Total Symptom Score (TSS) or Visual Analog Score (VAS) was examined at intervals of 7 days. Result: Laboratory data showed no abnormal signs compared with those of initial examination. The patient's subjective symptoms were rapidly relieved within one month. Also, the sums of TSS scores (upper limbs/lower limbs) decreased from 13.64/7.32 to 3.32/3.32 points, and VAS scores (upper limbs/lower limbs) improved from 19/10 to 6/8 points. Conclusion: This case presents a possibility that Oriental medical treatment may offer potential benefits (from an approach aimed at relieving of pain) for patients with chemotherapy-induced neuropathic pain.

Magnetoencephalography (MEG) records the magnetic field generated by electrical activity of cortical neurons. The signal is not distorted or attenuated, and it is contactless recording that can be performed comfortably even for longer than an hour. It has excellent and decent temporal resolution, especially when it is combined with the patient's own brain magnetic resonance imaging (magnetic source imaging). Data of MEG and electroencephalography are not mutually exclusive and it is recorded simultaneously and interpreted together. MEG has been shown to be useful in detecting the irritative zone in both lesional and nonlesional epilepsy surgery. It has provided valuable and additive information regarding the lesion that should be resected in epilepsy surgery. Better outcomes in epilepsy surgery were related to the localization of the irritative zone with MEG. The value of MEG in epilepsy surgery is recruiting more patients to epilepsy surgery and providing critical information for surgical planning. MEG cortical mapping is helpful in younger pediatric patients, especially when the epileptogenic zone is close to the eloquent cortex. MEG is also used in both basic and clinical research of epilepsy other than surgery. MEG is a valuable diagnostic modality for diagnosis and treatment, as well as research in epilepsy.

Epilepsy is a neurological condition that from time to time produces brief disturbances in the normal electrical functions of the brain, Normal brain function is made possible by millions of tiny electrical charges passing between nerve cells in the brain and to all parts of the body. They may affect a person's consciousness, bodily movements or sensations for a short time. These physical changes are called epileptic seizures. These clinical data, gathered an epileptic seizure whose main symptom was convulsion, was analyzed. This clinical report pertains to a 51 year-old man who suffered an epileptic seizure and after effects of weakness. He was treated with ChongsimOndamTang(淸心溫膽湯). The cheif symptom, epileptic seizure, disappeared and general conditions improved after Korean medical treatments, so this is reported as a potential treatment.

Purpose: The purpose of this study was to identify the performance status and quality of life (QOL) of patients after hematopoietic stem cell transplantation (HSCT) according to period of survival. Methods: Participants consists of 83 HSCT patients who were being treated regularly at out-patient clinic in two general hospitals in D city. Data were collected using questionnaires that were modified by Functional Assessment of Cancer Therapy-Bone Marrow Transplabtation (FACT-BMT) scale and Eastern Cooperative Oncology Group (ECOG). Results: The unrelated HSCT group's survival period was significantly worse than related HSCT group and autologous HSCT group. Performance status of the group with more than 3 years survival was significantly higher than that of the group with less than a year survival. The mean score of total QOL of HSCT patients was 2.69 out of 4. Total QOL was not significantly different among period of survival less than 1 year, 1-3 years, and more than 3 years. But BMT QOL was shown that the group with more than 3 years survival was higher than the groups with less than a year survival. Conclusion: Performance status and BMT QOL of the group with less than 1 year survival was significantly lowered than the groups with more than 3 years survival.
