The Abyei Conflict, concerning all the tribal competitions, political confrontations and even armed disputes over the Abyei area, has been one of the core issues in Sudan's war and peace. The seasonal water factor of Central Sudan naturally constituted a competitive relation between Ngok Dinka and nomadic Misseriya over cattle-grazing right in Abyei Area. Aggravated by the British administrative intervention, the conflict began to play the key role in several deadly civil wars in Sudan since independence of 1956. It also turned out to be one of the difficult issues to be agreed in peace process leading to the Comprehensive Peace Agreement(CPA) of 2005. This tenacity of the conflict has never yielded ever since CPA was signed to be implemented in 2005. Repetitive violations of the implementation of CPA, either active or inactive, were followed by renewed pledges from both the Government of Sudan(GoS) and Government of Southern Sudan(GoSS) in the form of written agreements. Neither have boundaries been delimited nor has Abyei Referendum been held while the scale of armed fighting between the North and the South since CPA keeps escalating. The latest army operations of GoS, based upon previously learned experiences, cast a dark shadow alluding the possibility of another civil war in Sudan. Abyei Conflict is unlike to be resolved in peaceful manner because the significance and water resources of Abyei Area reign over domestic politics in each side. Proxy war waged by tribal militias would be going to lead to another civil war that might be a full-scale armed conflict between the north and the south because it is much more intertwined to play a hinge factor with other confrontations such as in Darfur, Eastern Sudan and the rest of the Three Areas. It also brings geopolitical influence to neighboring African countries. Continuous attention and observations in the long term will be required to this conflict to bring about severe tension, war or bad peace in Sudan.

The ESDP engagement in the peace and security of Africa since the European Security Strategy

최필영(CHOI Phile Young) 육군사관학교 화랑대연구소 2011 한국군사학논집 Vol.67 No.1

This study reviews the eleven ESDP(European Security and Defence Policy)engagements to date in Africa since the European Security Strategy(ESS) in order to analyse the role, implications and limitations of the EU as an international security actor in African peace and security. The EU defines itself as an international security actor in the ESS that also requires the EU to grow to be a more active and more capable actor, but precise modalities are not given. It has declared enlarged responsibility to the peace and security in Africa where it has undertaken four pure military operations and seven civil or hybrid missions with several institutionalized capabilities. In doing so, it also tries to keep close cooperations with other international organizations. Its personnel strength and military capabilities are still not sufficient. Same problems are also observed repeating such as tough coordination within EU institutions, EU member states and with other international organizations. These challenges could affect the EU's credibility and efficiency, but they cannot deny the status of a comprehensible actorness of the EU in Africa.

본 연구에서는 스포츠급 경항공기 모형의 공력 특성을 공군사관학교 아음속 풍동에서 측정하였다. 풍동시험은 유속 40m/s에서 이전 모델과 최근 공력성능 향상을 위해 보완된 모델에 대해 비교 실험 수행하였으며, 정확한 데이터를 얻기 위하여 흐름각효과, 벽면효과, 지지대 간섭효과를 보정하여 공력계수를 산출하였다. 실험 결과, 두 모델의 항력계수와 양력계수가 전체적으로 유사한 경향성을 보이나 고받음각에서의 양력특성의 차이가 발생하였다. 또한 실제 비행시의 레이놀즈 수 유동을 모사하기 위하여 Trip strip의 영향에 대하여 실험하였다. 그 결과 Trip strip을 부착하였을 경우 항력계수가 증가하고 최소항력받음각이 낮아지는 결과를 획득하였다. In this study, Aerodynamic characteristics of light sports airplane shapes were measured at subsonic wind tunnel laboratory in Korea airforce academy. The wind tunnel test are performed with two different models at the velocity of 40m/s. To obtain accurate data, we corrected characteristics considered flow angle effect, wall effect and strut effect. As a result, Drag and lift coefficient of two models had similar tendencies in general, however, the difference of the characteristics of lift was presented at the high angle of attack. Also, the effect of Trip stip are investigated for simulating similarly with the Reynolds number of an actual flight condition. Consequently, when the trip strip attached on the wing, the drag coefficient increased and the angle of attack of minimum drag was lower.
