Lauge-Hansen's classification system and Weber's classification system are the two most commonly used systems in ankle fractures. Both are based on causative mechanism but both have some deficiencies. Authors intended to decide which is easily applicable in clinical practice and which provides more information about treatment, especially that of diastasis. So we analysed 143 cases of ankle fractures in Seoul National University Hospital, Kang-nam General Hospital and Namseoul Hospital from January 1983 to December 1988. The results obtained are as follows. 1. Weber's type A fractures correspond not only supination-adduction but also to pronation-abduction and pronation-dorsiflexion, Type B fractures correspond most closeiy to supin- ation-external rotation and possibly to pronation abduction and pronation external rotation. Type C fractures show the nearest equivalence to pronation-external rotation and occasionally correspond to supination-external roation or pronation-abduction. 2. Diastasis was no(ed in 16 cases(28%) of type B and in 18 cases(74%) of type C and this lower incidence was seemed to be due to neglect of diastasis at physical examination or during operation. 3. It seemed to be more reasonable to fix the diastasis with tibiofibular fixation screw especially in type C. 4. Weber's simpler classification system, which can explain the hidden ligamentous injury such as diastasis, was more easily applicable in daily use than Lauge-Hansen ciassification.

항행선박이 계류중인 선박에 미치는 간섭영향에 관한 연구
이춘기 한국항해항만학회 2011 한국항해항만학회 학술대회논문집 Vol.2011 No.추계
본 연구에서는 부산항 신항 선박급유 및 유류중계기지 건립에 따른 JETTY 평면재배치 검토로 인하여 발생되어지는 부산항 신항에 입항하는 대형 컨테이너 선박이 계류중인 선박에 작용하는 간섭력을 수치적으로 계산하고, 계류중인 선박의 안전 및 유류중계기지 건립 안전에 유의해야 할 점 등에 관하여 검토한다.

Many sea accidents such as collisions and groundings of vessels were occurred due to the lack of sufficient manoeuvring capability of vessels. Therefore IMO adopted "The interim standards of ship manoeuvrability by Resolution A.751(18)“ and the standards have been applied to vessels of 100m or more in length and all chemical tankers and gas carriers regardless of the length, which were constructed on or after 1 July 1994. The IMO manoeuvrability standards are divided into three kinds as bellows; (1) Turning capability standards : Estimated values in design stage are to be certified by turning circle test of the actual vessel. (2) Course keeping quality standards : Estimated values in design stage are to be certified by and Zig-Zag tests of the actual vessel. (3) Shortest stopping distance standards : Estimated values in design stage are to be certified by the shortest stopping distance tested by the actual vessel. In this paper, the authors computed the values of the manoeuvring standards of several vessels from their original design and compared them with those results from experiments of the model ships and also examined the values and concluded about the validity of IMO manoeuvrability standards. 대형선박의 충돌 혹은 좌초와 같은 많은 해양사고는 선박의 조종성능 부족으로 인하여 발생되고 있다. 따라서 IMO(국제해사기구)에서는 1994년 제18회 총회에서 결의서 A.751(18)로서 선박조종성에 대한 잠정기준을 채택하였고, 이 기준은 1994년 7월 1일 이후 건조된 길이 100m 이상의 선박 또는 길이에 관계없이 모든 케미컬탱커 및 개스운반선에 대하여 적용된다. IMO 조종성기준은 크게 설계단계에서의 선회성능과 보침성능 및 최단정지성능으로 대별된다. 이 논문에서는 몇 척의 대형선박에 대한 최초 설계단계에서의 자료를 이용하여 조종성능에 관한 계산 및 시뮬레이션을 행하고, 계산된 결과를 모형실험 결과와 비교, 검토하였으며, IMO 조종성기준의 타당성에 관하여 검토 고찰하였다.

Development policy has brought many difficulties and inconveniences as its by products to the daily life of community residents. Thes outcomes are caused by the policies emphasizing more on economic growth than welfare of people. There is no institutionalized citizen participation in local administration, and people scarcely have chances to reflect their opinions in the process of policy-making or planning in advance. Therefore most policies are likely to be made by administration without consultation with community residents beforehand. Under such situation the community residents have to take collective action to appeal or protest authorities for the elimination of difficulties imposed upon them. These collective actions are refered to as the movement of community residents. These movements are of non-political, spontaneous, and collective actions which have no links with existing organizations in the community. The rising of these movements have significant meaning where there is no institution for citizen participation and where people traditionally have little interest in public affairs. We can point out several meanings a) It is the fact that learning takes place on the part of community residents participating in the movements. For they not only need to identify with their problems but also understand what relationship they have with total community life. b) Learning also takes place on the part of administration in the process of argument on policies with community residents. They have to study and learn to carry out policies based on the welfare of people in the future.
