Strategic Geography of Northeast Asia and itsImplications to Korean Security The post-cold war security structure in Northeast Asia, which progresses from the remains of old historical conflicts and the cold war, is unstable. Major powers in the region cooperate for peace and stability, while competing for dominance and stronger influence at the same time. This eventually results in deepening a new shape of regional confrontational structure. Unlike Europe, which rapidly proceeded its cooperation and integration after the collapse of the cold war system, Northeast Asia has shown increasing conflict and division. The demise of the cold war system, instead of enhancing peace, opened the factors of conflict that had been concealed before. Many experts analyze that vestiges of traditional conflict and the Cold War may become a cause of military confrontation. This paper aims to analyze changing direction of regional security structure and its implications to Korean security. It analyzed the changing trends of regional powers' security and military strategies and the structural characteristics of their conflict and competition. Next, we studied how the shift in regional strategic geography affects the Korean security, and then made suggestions on which security strategies
Lupus anticoagulant-hypoprothrombinemia in healthy adult
정춘해,박치영 대한내과학회 2008 The Korean Journal of Internal Medicine Vol.23 No.3
The presence of lupus anticoagulant is associated with an elevated risk of venous and arterial thrombosis, and recurrent miscarriages as well. For some cases, this disease can present with bleeding as a consequence of lupus anticoagulant‐hypoprothrombinemia (LAHPS). LAHPS is a rare disease and it is reported to be most frequent in young females with/without systemic lupus erythematosus or in healthy children who are suffering with a viral infection. In such cases, steroid therapy is usually effective in normalizing the biological abnormalities and controlling the bleeding problems. A 34-year-old previously healthy man was admitted to our department because of his prolonged coagulation times; these abnormalities were discovered before performing orthopedic surgery. The prothrombin time (PT) was 15.2 sec, and the activated partial thromboplastin time (APTT) was 37.7 sec. A 1:1 dilution of patient plasma with normal plasma nearly corrected the PT, but this failed to correct the APTT. Evaluation of the clotting factors revealed decreased levels of factors II, V, VIII, IX and XI. The presence of LA was demonstrated by the dRVVT test, and the patient was diagnosed with LAHPS. He was successfully treated with corticosteroid before performing the orthopedic surgery.
