In this study the comparative analysis of four nations' Delphi technological forecasts in information and communication industry was carried out. The nations were Korea, Japan, Germany and France. The reliability test of realization time forecast was also conducted. There were some technologies of which four nations forecast almost same realization time whereas other technologies which four nations showed large variance in forecasting realization time. This means that experts from different nations had different views and prospects on the same technology. It is expected that prospecting international technological trend from this study will contribute to formulating long-range plan for technological development in information and communication in Korea. The result of the comparative analysis of four nations' forecasts in information and communication technology can be summarized as follows. a)As for the realization time, most of the technologies were forecast by four nations to be similar, the differences ranging from one to three years. It was found that on the whole, the longer the time of the forecast, the bigger the variance. The German forecast showed the biggest variance. b)In reliability test Korean was found to be the most reliable and Japan, France and Germany were in descending order. The response of all panel members was found to be more reliable than that of the panel members with high expertise, which means that there were substantially different views among panel members with high expertise on the realization time of the same technology.

Serial computed tomography (CT) was done on 168 patients suffering from craniocerebral trauma. The type of initial intracranial lesion in response to primary impact site was evaluated with special reference to the initial Glasgow Coma Scale(GCS), the number of specific CT findings on GCS outcome, and she skull fracture on resultant pathological findings. The development of delayed intracranial lesion, both intra-and extra-dural, was examined by comparing the initial scan with follow-up studies. The conclusions are as follows: 1) The initial GCS has a close relationship to outcome. 2) Initial CT findings(intraventricular hemorrhage, subdural hematoma, cerebral swelling, and subarachnoid hemorrhage) appear to be closely associated with poor outcome. 3) The more the number of initial pathological findings, the poorer the outcome. 4) The CT findings with skull fracture cause much more pathology than those without skull fracture. 5) The frontal lobe is shown to be the most vulnerable contusional site. 6) Delayed traumatic intracerebal hematoma, cerebral edema and cerebral infaction as new lesions encountered on subsequent CT scan have a bad outcome. We conclude that initial and follow-up scan help predict the outcome of patient with craniocerebral trauma, and may be very important in their examination and management.

212 cases of hypertensive intracerebral hematoma were treated and followed for more than 3 months. The outcome was analysed in point of comparison between conservative treatment and operative treatment. The precipitating factors on prognosis depend on size and site of hematoma, level of mental deterioration, and blood pressure on admission. Operative treatment showed better outcome than conservative treatment in cases of severely mentally deteriorated patients, large hematoma, and pontine hematoma.

본 연구에서는 장애인의 이동을 방해하는 도로 경사와 같은 물리적 장벽을 제거하는 데 필요한 정보를 제공하는 일련의 과정을 진행한다. 실험을 통해 고령층, 장애인이 안전하게 목적지로 이동하는데 필요한 IoT 기반 시스템 구현이 가능하도록 하는 정량화된 노면 평탄도 지수를 구현한다. 이를 위해 사전 연구로 자이로스코프를 이용한 노면 측정 장치를 고안하였다. 본 연구에서는 주행 중 노면의 거칠기, 평탄도를 확인하기 위해 자이로스코프로부터 X, Y변위, 가속도변위 세 가지 변수를 계측하였고 측정된 데이터의 연산과정을 통해 노면의 거칠기와 평탄도를 0 ~ 100으로 정량화하는 1차 가공 과정을 수행하였다. 이를 다시 4단계로 구분하여 지도에 표시하여 사용자에게 제공할 수 있는 알고리즘을 구현하였으며, 최종적으로 장애인 및 노인 전동휠체어 사용자가 기본 이동성을 확보할 수 있는 시스템을 구축하였다. In this study, the process of providing information necessary to remove physical barriers such as road slopes that obstruct the activities of the disabled is in progress. Through experiments, we implement a quantified road surface roughness index that enables the implementation of IoT-based systems necessary for the elderly and the disabled to safely move to their destination. As a preliminary study, a road surface measurement device using a gyroscope was devised. To check the roughness and flatness of the road surface, X, Y displacement, and acceleration displacement were measured using a gyroscope. By calculating the measured data, the roughness and flatness of the road surface were quantified from 0 to 100. We implemented an algorithm that divides this index into 4 stages, displays it on a map, and provides it to users. Finally, a system for the disabled and elderly electric wheelchair users to secure basic mobility was established.
