본 연구는 정보화의 진전에도 불구하고, 항만물류 정보서비스와 관련한 연구가 매우 부족하다는 점에 주목하여, 인천항 정보서비스의 실태를 분석하는 것을 목적으로 수행되었다. 연구의 목적을 달성하기 위하여, 본 연구에서는 크게 2가지 측면의 실태 분석을 실시하였다. 우선, 중요도-만족도 분석기법(IPA)을 활용하여, 인천항 정보서비스를 이용하는 사용자를 대상으로 인식조사를 실시하였다. 그 결과, 통합데이터베이스를 통한 통합정보제공수준, 정보조회서비스의 다양성, One-STOP 정보제공 수준, 오류정보의 신속한 처리 측면에서는 중요도에 비해 낮은 만족도를 보이고 있어, 이 부분에 대한 우선적인 개선방안이 수립되어야 할 것으로 판단된다. 다음으로, 인천항만공사 및 인천항 포털사이트의 웹 기능성 평가를 실시하였다. 그 결과, 웹 접근성 지침에 따른 준수율의 경우, 2가지 모두 60%대로서, 미흡한 수준인 것으로 파악되었다. 또한, 웹 성능 최적화 분석에서는 인천항 포털사이트가 매우 낮은 등급인 F등급을 받아 이 부분에 대한 개선책 마련이 필요할 것으로 판단된다. Advances in information and communication technologies have made the Internet and mobile devices popular media in both the business world and in daily life. These technologies are widely recognized as indispensable tools for all activities. A port is operated on the basis of information about cargos and ships, and hence port operations rely significantly on information and communication technologies. The information services that a port provides are essential services for port users, including shipping and inland transportation companies. Moreover, due to rapid changes in the world trade and shipping environment, today`s ports face ever-increasing competition from adjacent ports. Thus, the provision of good information services for port users has been recognized as an important strategy for maintaining port competitiveness. However, despite its importance, there has been little research on the current status and utilization of the port-logistics information service based on a field survey. The aim of this paper is to analyze the actual status of the port-logistics information service that Incheon port provides. Towards this objective, we conducted Importance-Performance Analysis (IPA) and evaluated the port`s website functionality. IPA is an evaluation tool that is used to prioritize attributes for improvement and that can also provide guidance for strategic development. For IPA, 17 evaluation items from previous related studies were adopted and data was collected from port-logistics companies that use information services provided by Incheon port. For the evaluation of website functionality, we used K-WAH(Korean-Web Accessibility Helper) and YSLOW. K-WAH is a representative tool to estimate web accessibility. YSLOW is a tool used to estimate the level of web-optimization, and comprises 35 evaluation items, including usage of a content delivery network, Gzip components, and making Java Scripts and CSS external. The results of the empirical data analysis revealed that there are gaps between overall importance and satisfaction of information service. Especially, it highlighted that Incheon port had several weak points: unification of information through database integration, one-stop information service, variety of information, and prompt dispatch of error information. Based on the evaluation of website functionality, it was found that the homepage and portal of Incheon port had several problems. Both the websites` accessibility compliance rate in accordance with K-WAH was less than 70%, implying low levels of web accessibility. In the web-optimization analysis, Incheon port`s portal obtained a very low, F grade, implying that it has serious problems with processing a variety of user requirements in information service. As the information volume rapidly increases, the loading speed of the website becomes much slower. In order to solve this problem, it is necessary to optimize the website.

만성 뇌경막외 혈종 : 2예 보고 Report of Two Cases
강영우,이봉암,이영근 대한신경외과학회 1979 Journal of Korean neurosurgical society Vol.8 No.2
Extradural hematomas are usually acute and rapidly progressing and the lucid intervals generally varies from a few moments to several hours. However, not uncommonly, an epidural hematoma may have a lucid interval lasting weeks, months or even years, which may present as a chromic epidural hematoma. Two cases have recently come under our care, demonstrating a paucity of objective neurologic abnormalities, but with extensive compressive extradural hemorrhage, which were found incidentally during the screening examination with the CT scanning.
