Background : Patients with chronic renal fialure have a substantially elevated risk of death from cardiovascular diseases than do the general population. the patients with chronic renal failure are at significantly increased freqeuncy of hypertension, hyperlipidemia, and diabetes mellitus which are known to the risk factors of the coronary artery diseases, and the prevalence of the coronary artery diseases in chronic renal failure patients is highly associated with the hemodynamic disorder and metabolic abnormalities. therefore we expected that the coronary angiographic findings in patients with chronic renal failure should be different from the general population (control groups) and investigated the risk factors contributing to coronary artery diseases. Method : we have retrospectively compared the coronary angiographic findings of 44 patients with chronic renal failure on hemodialysis with that of 88 patients in the general population and investigated the factors contributing to the development and acceleration of coronary artery diseases in patients with chronic renal failure Result : Hypertension and diabetes mellitus which is risk factors for coronary artery disease is significantly increased in patients with chronic renal failure, in coronary angiographic finding the severity of the lesion is worse. the incidence of PCI or CABG of patients with chronic renal failure is more than that of control group but statistically no difference between patients with chronic renal failure and control group. the sex, the duration of disease, the duration of dialysis, serum creatinine in patients with chronic renal failure have no correlation to the prevalence of coronary artery disease and severity of lesion. hyperglycemic patients with chronic renal failure have high incidence of coronary artery disease and are worse in the severity of lesion Conclusions : There is significantly increased the pevalence and severity of involving multiple coronary artery diseses in hyperglycemic patients with CRF.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.

The EU and East Asian Security

Dae Won Ohn 한국유럽학회 2009 유럽연구 Vol.27 No.2

탈냉전 시대 유럽연합 (EU)의 대동아시아 정책의 특징적인 요소 중 하나는 역내 국가들과 끊임없이 증대하는 상호의존과 제휴관계에 대한 매우 적극적이고 포괄적인 접근방법이다. 이 지역에 대한 EU의 공동정책은 회원국들의 경제적 이익증진 및 국제정치적 행위자로서의 EU의 위상증대와 더불어 역내 국가들과의 협력을 통하여 각종 안보문제를 효과적으로 다루는데 그 주안점이 두어졌다. 이 논문의 목적은 EU가 공동외교안보정책 (CFSP)과 유럽안보방위정책 (ESDP) 분야에서 동아시아에 대해 수행하고 있는 공동정책의 발전 추세와 한계, 그리고 향후 전망을 고찰함에 있다. 지난 15년간 EU의 동아시아 안보정책의 발전은 CFSP와 ESDP에서의 회원국간 협력 및 정책통합의 추세와 맥을 같이해왔다. 그것은 또한 탈냉전시대 이 지역 국가들과의 협력의 중요성에 대한 유럽 정책결정자들의 새로운 인식과 기대를 반영하고 있다. EU는 제도, 정책수단, 지도력, 전략문화 등 여러 요소에서 아직 상당히 미약하고 불완전하지만, 자신이 보유하고 있는 다양하고 풍부한 “연성권력” 자원들을 효과적으로 활용하고, 적절한 수준의 군사적 능력을 확보할 경우 동아시아 안보에서 상당히 중요한 역할을 할 가능성을 갖고 있다. 상대적으로 비위협적인 역외의 안보행위자로서 EU는 새로이 부각되는 다양한 안보문제를 다루는데 여러 가지의 장점을 갖고 있는 것으로 파악된다. The defining feature of the European Union (EU)`s policy towards East Asia in the post-Cold War era has been ever increasing interdependence and partnership with the countries in East Asia. EU`s evolving common policy on the region has been aimed at more effectively dealing with the old- and new- security problems while reinforcing the economic and commercial interest of the member states and the visibility of the EU as an actor in international politics. This paper examines both the potential and limit of the EU to carry out a common policy towards East Asia in the field of the CFSP and the ESDP. It is understood that the development the EU`s security policy vis-a-vis the region has been in parallel with the tendency moving towards a higher level of cooperation among the member states in the field of foreign and security policy. It was also based on their renewed recognition on the need to foster a political and strategic cooperation with East Asian countries. Still weak and imperfect it may be with regard to institutions, instruments, leadership and strategic culture, EU`s affluent “soft power” resources supplemented by its modest but increasingly more effective military capability would enable the Union to play its role as a security actor in East Asia in significant ways. As a non-threatening or less-threatening security actor, the EU seems to have many advantages in dealing with various security issues in the region as a third-party player.

Cooperation on Counter-Piracy in the Gulf of Aden among China, Korea, and Japan: Implications for Trilateral Security Cooperation in Northeast Asia

( Dae Won Ohn ),( Mason Richey ) 한국국방연구원 2014 The Korean Journal of Defense Analysis Vol.26 No.1

Northeast Asia`s regional cooperation is abysmal. Although China, South Korea, and Japan have generally compartmentalized bilateral trade relations in order to ensure continuing prosperity of their respective economies, regionally institutionalized cooperation remains weak, even in this domain. Trilateral political and security cooperation among these states is virtually nonexistent. China`s disinclination (as an emerging regional hegemon) toward regional cooperation and Japan`s failure to settle its historical problems are regarded as the key reasons for the lack of such a development. Yet despite this fraught situation the prospects for regional cooperation among the three main Northeast Asian powers have seen glimmers of hope. This paper argues that security is surprisingly one of the areas where scholars and practitioners envision a foundation for increased opportunities for regional cooperation. The most noteworthy case is the ongoing coordination among China, Japan, and South Korea (along with some others) to fight piracy in the Gulf of Aden area. Beyond the result of reducing piracy on commercial shipping, the counter-piracy effort has fostered cultural exchange among the region`s different navies and coastguards, offering opportunities for growing the spectrum of maritime security expertise beyond what each country would be able to do alone. This paper looks at the implications of this combined effort for other potential areas of cooperation among the Northeast Asian states.
