To stabilize white OLEDs with the operating voltage by two wavelengths methods, we synthesized the novel blue emitting material based on methyl & methoxy substituted DPVBi materials. Two types of light emitting devices were processed, which type I was ITO/TPD/methyl-DPVBi/Al and type Ⅱ was ITO/TPD/methoxy- DPVBi/Al structure. The PL peak wavelengths of two devices were 483㎚, 506㎚ respectively. And they were shifted to the longer wavelength compared to DPVBi(450㎚) due to electron donation effects. The peak EL emission wavelength of devices were 468㎚, 535㎚ respectively at 15 Volt.

Background: Triage and transportations are important and life-saving medical task performed at the site of mutiple-casualty incidents(MCIs). We pursued three road traffic accidents victims to find out any problem in triaging and transporting them, and to provide an information for equipping an local disaster planning. Methods: The medical records of 70 consecutive patients who were transported to five emergency facilities in Kangnung, on three MCIs from 1998 to 2000, were analysed, retrospectively. The intervals and types of transport vehicles were analysed. We compared the prehospital time between severity-based groups, which were graded into 3 groups according to the Triage score(0,1~8,9). Results: Among the 70 patients, 33 patients(47.1%), 21 patients(30%), and 16 patients(22.9%) were transported to Level I, Level II, and Level III trauma centers, respectively. The time elapsed from scenes to the Level I trauma center was significantly shorter(p=0.003) than to others, but no differences in the mean Triage score between trauma centers were seen(p>0.05). The 119 rescue services transported 58.6%(41 patients) of victims to emergency facilities, and 58.5%(24 patients) of them was concentrated to Level I. There were no significant differences in the prehospital time between three Triage score groups(p>0.05). Conclusion: There was no medical control such as triage and transportation in the cases of three MCIs. In the construction of emergency medical service system(EMSS) preparing MCIs or disasters, we suggest the integration and unification of 119 rescue services and emergency medical information centers for effective medical control. We propose to making a new and simple triage guideline. The prehospital personnel should be educated and disaster drills should be performed under the guideline.

This study aims at exploring the effect of leadership type on Taekwondo trainees' development in sociality. in order to help as a reference for a Taekwondo training. The measuring instrument(Leadership Scale for Sport) used in the survey was developed by Chellandurai and Saleh(1980) and revised by Kim(1990). Items related with development in sociality argued by Ahn(1997) and Yeon(2001) were also used. Data were processed through SPSS. Frequency analysis was done to figure out background variables of the objects. Reliability analysis was done to verify the questionnaire reliability. Multiple regression was used to explore the effect of leadership behaviors on the trainees' development in sociality. The results were as follows Firstly, social supporting highly affected sub-factors of sociality development such as trust, justice. and patriotism. Secondly, positive rewarding behaviors highly affected sub-factors of trainees' sociality such as language use habits, responsibility. Thirdly, training and instructing behaviors by the trainers highly affected trainees' teamwork. When synthetically looking, it was found that trainees' development in sociality had various sub-factors as did the trainers' types. Accordingly, it was thought that proper custom-made training in developing sociality was important to trainees.

Schizencephaly is an infrequent congenital disorder of neuronal migration characterized by gray matter-lined clefts that extend through the entire cerebral hemisphere, from the ependymal lining of the lateral ventricle to the pial covering of the cortex. We have studied seven patients with schizencephaly rstrospectively to correlate clinical outcome with the type, size, and location of the clefts and to find associated brain anomalies. Three patients had bilateral clefts(one with two open lip clefts and the other two with a left open lip cleft and a right closed lip cleft), another two patients had left unilateral open lip clefts, and the rest two patients had right closed lip clefts. Clinically these patients presented motor dysfunction such as hemiparesis, seizures, and variable developmental delay. Patients with bilateral clefts, paticularly open lip type had worse motor and developmental impairment than those with unilateral clefts. Patient with unilateral medium open lip cleft had worse motor and intellectual impairment than those with unilateral closed lip clefts or small open lip cleft. All patients with f개ntal lobe involvement had motor dysfunction. Absence of septum pellucidum, gray matter heterotopia, polymicrogyria, and hypoplasia of optic nerves were also frequently found to be associated with schizencephaly. Three patients with skull changes such as enlargement of the hemicranium of erosion of the inner table of the skull were shunted but only one patient improved in the imaging study We conclude that the severity of patient's symptoms is related to the amount type and location of the involved brain.

However, even the most technically perfect anastomosis can neither eliminate the damage which microneedles cause on the vascular endothelium nor foreign body reaction to the suture material. Thrombosis developed at the suture site and regressed if the stimulus for the thrombosis is not severe. Partial thrombosis was inevitable after microvascular anastomosis. Since systemic thrombolytic drugs were used initially in the management of pulmonary emboli, urokinase were also used in prevention of thrombolysis and thrombolysis after microvascular anastomsis. This experimental study includes the effect of urokinase on the microvascular anastomosis in rabbits. The patency was observed, and platelet count, fibinogen, prothrombin time, and activated partial thromboplastim time were examined. In the case of thromboses, the anastomotic sites were resected and examined microscopically. The results were as follow; 1. The patency rate was increased 15 percent in experimental group than control group. 2. There were no differences in platelet count and the prothrombine time between experimental and control group. 3. The level of fibrinogen was decreased 157㎎/dl in experimental group less than control group. 4. The activated partial thromboplastin time was increased three to four times at postoperative period more than preoperative period in experimental group. 5. In light microscopic examination of thrombotic vessel wall revealed inflammatory reaction to suture material. In the experimental group, the thrombi were loose and defibrinated than control group.

The disabled has remarkable difficulties to participate social activities and those, that block them up from access to public facilities and the comfortable habitation so they should get help from others, are mainly made by architectural facts. Buildings without impediment which consider the disabled would be the things responding to the needs of the times. If the disabled would be convenient to use facilities, there should be no difficulties to normal people. A first began to examine into the role of the architecture. And to establish radical standards for the disabled to use cultural and assembly facilities through scrutinizing facilities to get access for the disabled and movement circulations in the cultural facilities should be the conclusion. This study which is a kind of fundamental study to construct cultural facilities without obstacles for the disabled began from consideration for the problem flow line of the disabled in cultural facilities and analyzed flow lines for them to use, access, and evacuate from those which are main facilities in the region. Though, evacuation rules in cultural and assembly facilities are recommendatory in existing laws for convenience of the disabled, the congestion of the crowd coming out after performances impedes safe flows of both the disabled and crowds. Further, in case of evacuation, there would be more serious problems. Therefore, consideration of reinforcement for existing laws for convenience of the disabled is needed.
