와이블 분포를 이용한 소형 풍력의 풍력 에너지 밀도 분석

조관행(Kwan-Haeng Cho),윤재옥(Jae-Ock Yoon) 호서대학교 공업기술연구소 2011 공업기술연구 논문집 Vol.30 No.1

최근 기후 환경적 문제와 에너지 소비의 급격한 증가로 풍력 에너지와 태양에너지 둥 신재생 에너지에 대한 관심이 증가 하고 있다. 특히, 소형풍력발전기는 전기를 사용하는 대학 캠퍼스나 주거 단지에 설치하면 송전 비효율 성을 낮추어 주는 장점이 있어 크게 주목되고 있다. 본 논문에서는 H대학교에 설치된 AWS(자동기상관측장비) 자료와 서울지역의 10년간 AWS를 분석하여 얻은 와이블 계수를 외국과 비교 분석 하였다. H대학교는 와이블 분포의 C값은 2.27, K값은 0.88이다. H대학교 와이블 분포에 따른 15m에 설치한 소형 풍력 에너지 밀도는 12.7 W/m2이다. 소형 풍력 발전기를 이용해 발전을 했을 경우 연간 전기발생량은 4,514kWh이다. These days, interest in new renewable energy like wind and solar energy is increasing because of environmental issues of climate and rapid expanding energy consumption. Especially, by reducing power transmission inefficiency, a small wind turbine generating system is getting attention from universities and residential districts. This study attempted to estimate and compare wind energy density using meteorological data on AWS (Automatic Weather Station) of two areas; a H University and Seoul to other countries. In the case of a H University, a weibull distribution parameter C is 2.27, and K is 0.88. According to the data, the energy density of the small wind power generating system is 12.7 W/m2. In the results, the small wind power generating system can produce 4,514kWh annually.

카터 행정부의 주한미군 철수 결정에 대한 연구

The Purpose of the paper is to analyze the decision making process of the Carter administration"s U.S. troops withdrawal policy from the Korean peninsular based on the US and South Korea diplomatic documents which were declassified recently. After the presidential inauguration, Cater administration made the system of the Presidential Review Memorandums(PRM) and the Presidential Directives. And Carter ordered the review of the U.S. troops withdrawal on the National Security Council and related institutions. In order to analyze decision making process of U.S. troops withdrawal policy, this paper examined the PRM-10 and the PRM-13. Carter administration discussed the U.S. troops withdrawal plan through the Policy Review Committee(PRM) and the National Security Council.(NSC) subsequently, U.S. troops Withdrawal plan was released through the PD-12. Even though U.S. troops withdrawal policy was designed by the SCM between U.S and South Korea, Carter administration"s withdrawal policy determination was unilateral. This was derived from the fact that the United States stressed the Carter administration’ political positions than north korea military assessment. In conclusion, We should be definitely aware of determining the structure and process of the policy of the United States and, therefore, will have to make efforts to prepare for response on an ongoing basis.

카터 행정부의 북한 군사력 재평가

조관행(CHO Kwan-Haeng)(趙寬行) 신아시아연구소(구 신아세아질서연구회) 2011 신아세아 Vol.18 No.4

주한미군 철수 결정시 철수의 전제조건은 주한미지상군 없이도 한국이 미 공군과 병참지원만으로 북한에 대한 억지를 할 수 있다는 것이었다. 하지만 1979년 초반에 공개된 미 군사 지도자들의 북한 군사력에 대한 재평가는 이러한 기존의 가정과 전제조건이 잘못되었음을 나타냈다. 1979년 2월 철수 보류 결정 시, 철수 보류 발표 후, 한미정상 회담 시 등을 기준으로 최근에 비밀 해제된 한국의 외교사료를 중심으로 북한 군사력 재평가를 분석하여 다음과 같은 결과를 도출하였다. 우선, 1979년 1월 초, 아미타임스의 북한 군사력에 대한 공개이후, 미행정부와 의회 및 군부 간에 재평가에 대한 논의가 계속되었다. 하지만 시간이 경과할수록 주한미지상군만이 북한을 억제할 수 있다는 결론이 의회와 군부에서 동일하게 도출되었다. 따라서 카터 행정부는 1977년에 결정하였던 주한미군 철수정책에 대한 기반을 잃어버렸다. 결국, 이상의 논의를 통해 볼 때 주한미군 철수 중지 결정에 있어서 1차적인 원인은 북한 군사력에 대한 재평가였다. The possible withdrawal of USFK from ROK peninsula is based on the premise that ROK is capable to deter North Korean forces with only USAF and US Military logistics support without USFK. But according to the declassified reassessment of the combat power of North Korea by the US military elites in early 1979, it became apparent how the premise was misguided. Based on the declassified diplomatic documents from the decision and after the announcement of hold withdrawal in abeyance of USFK on February 1979 and the ROK-US summit, I have analyzed the assessment of North Korea’s military power by the US military elites and came to a few conclusions. First, after the release of North Korea’s military power on the Army Times, continued discussion about it resonated in the US government, congress, and the military. But after a while, the congress and the military came to a conclusion that only USFK can deter North Korean forces and naturally, the Carter Administration lost its ground to withdraw USFK from the peninsula. In conclusion, the first causal factor behind the withdrawal halt was the reassessment of the North Korea’s military power.

중국 군사혁신(RMA)에 따른 중국공군 현대화와 한국공군에 주는 함의

조관행 ( Kwan Haeng Cho ),홍성표 ( Sung Pyo Hong ) 현대중국학회 2011 現代中國硏究 Vol.12 No.2

걸프전 이후 중국공군은 군사혁신에 따라 군사전략 개념 및 공군교리를 발전시키고 이전의 육·해군 지원 전략개념을 벗어나 독자적인 역할을 수행하는 독립전력으로 성장하게 되었다. 이 글은 중국공군의 현대화를 항공전력 중심으로 분석하였다. 중국은 걸프전의 경험을 통해, 산업시대가 정보시대로 변화되었다고 인식하였으며, 군사혁신을 추구하고 있다. 그러나 현재 중국의 낮은 기술수준으로 서구와 같은 수준의 정보적 능력을 보유하는 것은 불가능하다고 인식하며 중국특색의 군사혁신을 추구하고 있으며, 현재 중국은 기계화와 정보화의 혼합적인 발전을 동시에 가속화하고 있다. 걸프전 이후, 중국은 공군교리를 전통적인 방어개념에서 공세적인 개념으로 변화시키고 있으며, 공군력의 운영이 국토방공에서 공수겸비로 전환 되고 있다. 중국공군은 이라크전 이후 정보화 조건하 국부전쟁 승리 개념을 충족 하기 위한 공군력의 증강에 우선순위를 두고 있으며, 공군의 주요한 요소 중 하나인 항공기 현대화를 위해 전력하고 있다. 결론적으로, 우리는 중국이 추구하는 군사혁신과 항공전력 현대화의 교훈을 통해, 한국공군이 한국특색의 군사혁신과 전력 현대화를 완성하여 한반도 전역을 주도할 수 있는 능력을 보유하는 것이 필요하다고 판단된다. This paper analyzes the process of People`s Liberation Army Air-Force(PLAAF) modernization, specifically its aircraft development, focusing on how it transformed itself into an independent force from the supporting force of the PLA and PLA Navy, through the Revolution in Military Affairs and the change in the perception of military strategies and Air-Force doctrines after the Gulf War. Through its observation of Gulf War, China realizes that the industrial age was replaced by the information age and actively pursues the RMA. However, with its less advanced technology, China finds it impossible to establish information warfighting capabilities comparable to those of the Western Countries and is currently pursuing RMA with Chinese characteristic. At present, China is accelerating the composite development of mechanization and informationization at the same time. Since the Gulf War, China has been developing its AirForce doctrines from a traditional defensive concept to offensive one and the employment of its air power is being converted from the homeland defense to the combination of offensive and defensive uses. PLAAF puts a priority on the improvement of air power to meet the concept of winning local wars under condition of informationization after Iraqi War and is making great efforts for the modernization of airpower. In conclusion, the lesson of PLAAF`s RMA and airpower modernization is that it is necessary for the ROKAF to make its own style of military renovation and to modernize its capabilities, so that it can play a dominant role in the Korea theater as an independent force.

풍환경 예측을 위한 CFD 시뮬레이션 Mesh Size의 모델링 타당성 검토

조관행(Cho Kwan-Haeng),이주희(Lee Ju-Hee),윤재옥(Yoon Jae-Ock) 대한건축학회 2011 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.31 No.2(계획계)

This phenomenon is causing various problems such as wind speed depend on building and building environment, gust. Especially, the gust around buildings layout makes severe problem in wind environment. To solve this wind problem, theory, field measurement, wind tunnel test and CFD simulation are used. CFD simulation method is widely used because of its convenience for time and cost. To predict the wind environment in campus area with CFD, the boundary condition and domain size, turbulence model for simulation should be set in correct. The mesh size has a great influence on the results. So, This paper will be discussed with the CFD results of variety mesh size(Volumetric Control Size)3, 5, 6, 7, 10m.

카터 행정부의 주한미지상군 철수결정 시 북한 군사력 평가에 관한 연구

조관행(Cho, Kwan-haeng) 국방부 군사편찬연구소 2011 군사 Vol.- No.81

The US troops in the Carter administration withdrawal policy was examined and executed just week after the presidential inauguration. Although most government organizations including the Department of Defense had regarded the station of USFK necessary, the Department of Defense admitted the withdrawal policy from the political perspective in the Carter Administration. However, military authorities had various thought on the evaluation on North Korea"s military capability. Meanwhile, CINCPAC and USFK continued to oppose the withdrawal but JCS and the US Army had opposed the withdrawal before the Carter Administration, changed their position to admit the withdrawal on the condition that there should be compensatory measures for the USFK withdrawal. In conclusion, the primary factor for the withdrawal policy was the Carter Administration"s political volition, and the secondary factor was the military evaluation that the ROK Army can defeat North Korean Army without the USFK"s Ground force if US Air Force"s support is pertinent. Here we can find out that the Carter administration"s political volition and the military"s evaluation alteration on North Korean military capability played a key role in deciding the USFK withdrawal policy.
