OBJECTIVE: In this research, a full-duplex transmission system was developed in order to send real time medical information(i.e. patient vital signs, real-time patient video/audio data) using HSDPA(High-Speed Downlink Packet Access), a 3.5th generation mobile communication system. METHODS: Transmission tests were conducted in an environment simulating that of the inside of a moving ambulance, transporting an emergency patient. The capability of the HSDPA system to transmit emergency medical information has been verified by comparing the prolonged cumulative data, calculating packet loss, and measuring transmission speed. RESULTS: Test results show that the system is capable of transmitting vital signal data, including 12 waveform data, 20 numeric data and 113 events. This provides enough information needed for medical guidance, reading the affected part of the patient, and forwarding 320x420 pixel images at 2fps. Full-duplex voice transmission at 8bit/64kbps is enough to permit reliable communication between emergency medical technicians and hospital professionals. A total of 11.43 kilobytes were lost out of 81.25 megabytes. Therefore, the packet loss was 0.013%. CONCLUSION: The medical transmission system using HSDPA performs well in data transmission speed and communication quality during emergency medical transportation. It is also expected to further improve emergency medical conditions if supplementary systems such as the standard protocol establishment.

PURPOSE: To examine the results of PBL classes for sophomore nursing students during one semester. METHOD: Self-reflection journals and class evaluation questionnaires were collected from 121 nursing students and analyzed. Results of class evaluation questionnaires were analyzed using mean scores, SD, frequencies and percentages. Significant statements were derived by repeated review of the self-reflection journals by the researchers. RESULTS: The statements, 'Understanding of PBL', 'Improvement of human relationships', 'Expansion of nursing knowledge', 'Excellency in nursing class and application of nursing skills in nursing practices' and 'Improvement of learning ability and attitude during classes' were derived from the self-reflection journals. Analysis of class evaluation questionnaires showed the following scores: prerequisite of PBL (3.0/4), role of facilitator (3.48/4) and satisfaction with PBL learning (3.31/4). Also some complaints such as lack of adequate references in the library, and confusion in at the beginning of PBL were noted. CONCLUSION: PBL was effective. Using the results of the study for planning a more effective PBL class syllabus is recommended.

BACKGROUND: We have already shown that a new vitamin D3 analogue, calcipotriol is a potent growth inhibitor for human keratinocytes, indicating the close relationship between the in vitro inhibitory effect of calciipotriol and its therapeutic effectiveness or psoriasis. OBJECTIVE: Our purpose was to evaluste the clinical efficscy, safety and tolerability of calcipotriol (50ug/g) ointment twice daily in the treatment of psoriasis. MEHTODS: We treated 31 patients with calcipotriol for 6 weeks. Patients were provided with a maximum of 100g of ointment per week. Efficacy, as measured by the Psoriasis Area and Severity Index(PASI), and safety were assessed at 2,4, and 6 weeks. RESULTS: Reduction of PASI was stastistically significant at all time points for treatments (p<0.01). At the completian of 6 weeks of treatment, the mean PASI reduction was 3.61. An analysis of patient overall self-assessment, at 6 weeks showed clearance or marked improvement in 61%. Some patients developed minimal irriltation of lesional or perilesional skin(6.5%). Laboratory tests did not show any significant changes, in particular there was no change in serum calcium levels. CONCLUSIONS: Calcipotriol ointment was effective as measured by the PASI and the self-assessment in patients with psoriaeis. This treatrnent was well tolerated.

To date, no cases of nasal septal perforation during or after chemotherapy in patients with acute leukemia have been reported. In this study, we report three acute leukemia patients that had septal perforation and saddle nose deformity after chemotherapy and the results of our attempts to determine the causes of this phenomenon. We investigated retrospectively the types of chemotherapeutic agents involved and the duration of chemotherapy until the development of the nasal septal perforation. In addition, we also studied whether there were any remaining malignant cells by biopsy from the septal perforation margin. We found that Ara-C was the only drug that was used in all 3 patients. Nasal septal perforation and saddle nose developed approximately 4~7 weeks after the chemotherapy. A biopsy revealed inflammatory cells but no malignant cell infiltration. In cases of saddle nose associated with septal perforation after the chemotherapy for acute leukemia, one may consider the possibility of side effects of Ara-C. Furthermore, more active diagnosis and treatment are required when patients with acute leukemia complain of epistaxis or nasal obstruction during or after chemotherapy.

Objective: This study aimed to evaluate the following null hypothesis: there are no differences in the morphology of the temporomandibular joint (TMJ) structures in relation to vertical and sagittal cephalometric patterns. Methods: This retrospective study was performed with 131 participants showing no TMJ symptoms. The participants were divided into Class I, II, and III groups on the basis of their sagittal cephalometric relationships and into hyperdivergent, normodivergent, and hypodivergent groups on the basis of their vertical cephalometric relationships. The following measurements were performed using cone-beam computed tomography images and compared among the groups: condylar volume, condylar size (width, length, and height), fossa size (length and height), and condyle-to-fossa joint spaces at the anterior, superior, and posterior condylar poles. Results: The null hypothesis was rejected. The Class III group showed larger values for condylar width, condylar height, and fossa height than the Class II group (p < 0.05). Condylar volume and superior joint space in the hyperdivergent group were significantly smaller than those in the other two vertical groups (p < 0.001), whereas fossa length and height were significantly larger in the hyperdivergent group than in the other groups (p < 0.01). The hypodivergent group showed a greater condylar width than the hyperdivergent group (p < 0.01). The sagittal and vertical cephalometric patterns showed statistically significant interactions for fossa length and height. Conclusions TMJ morphology differed across diverse skeletal cephalometric patterns. The fossa length and height were affected by the interactions of the vertical and sagittal skeletal patterns.
