Kwak Jae-Woo(郭再祐) was the first person to raise Righteous Army during Im-Jin-Wae-Ran(壬辰倭亂), and in this paper I intend to analyze and research into the significance and background of his raising righteous army in Ui-Ryeong(宜寧). Firstly, I have given insight to the historical background and significance of the raising in Ui-Ryeong. as discussed in previous researches, the reasons why the continuous defeats of Cho-Seon in the early stages of Im-Jin-Wae-Ran were due to disorder in military administration and slackened discipline in national defence; however this paper puts emphasis on the necessity of looking into the exterior influential factor of the Japan, the world’s strongest military powerhouse at that time. In addition, I have discussed how his competence as a commander of the Righteous Army was possible to be formed, since Kwak was also a general who has outstanding realistic judgment and a sense of neutrality; and also the solidarity of the Ui-Ryeong troops. Secondly, I argued that Kwak’s raising of the Righteous Army in Ui-Ryeong contains more significance than just being the first, since he was able to raise the Army albeit the deficient conditions, especially centered around his relationship with Seon-Jo(宣祖). Moreover, I have examined the fact that Kwak’s raising gave peace to the unstable public at that time, and served as a catalyst for other raising of righteous armies to occur. Thirdly, I have confirmed that the strategic effects of the raising army in Ui-Ryeong is not just limited to local defence of Kyeong-Sang-Woo-Do(慶尙右道) beyond that it provides a turning point to the Choseon government to protect Ho-Nam(湖南) and the naval forces bases, restrain the exile of Seon-Jo and lead the participation of Myung(明) troops into war. In the thesis I have examined the defense strategies that Kwak adopted to fight against the Japanese troops three major skills, bird-rifle(鳥銃), swordwielding, charging at enemies and defense strategies adopted when positioned in a river. Among recent researches on the history of Im-Jin-Wae-Ran Righteous Army are at standstill. I proudly present this paper, as I wish this paper serves as a catalyst of more academic endeavors on the Im-Jin-Wae-Ran Righteous Army.

해외 수처리 시장 진출 전략 개발을 위한 SWOT-ANP 적용 모델 개발

최재호,Choi, Jae-Ho 대한토목학회 2014 대한토목학회논문집 Vol.34 No.1

세계 물 시장은 소수의 다국적 물 전문기업, 물 전문 회사의 출현, 금융 기업의 참여, 비 건설 기업의 물 시장 참여 등 다양한 주체가 참여하고 있으며, 각자 물 관련 벨류 체인의 강점 분야를 주축으로 사업 영역을 확대하고 있는 추세이다. 본 논문은 이러한 해외 물 시장 진출을 희망하는 국내 비 건설 기업의 전략간 우선순위 도출 방법론으로 SWOT-ANP 연계 모델을 제시하고 그 결과를 AHP 모델과 실제 해당 기업의 사업 전개 내용과 비교 검증하였다. 본 모델은 SWOT 분석에 분석적 기능을 제공하고 SWOT 요소간 내부적 상호관계를 모델링하기 위한 ANP 방법론을 적용하였으며, 분석 결과 AHP로부터 도출된 전략간 우선순위와는 동일한 결과를 나타냈으나, 가중치의 변동이 발생하여 결과가 달라질 수 있는 개연성을 확인하였으며, 실제 기업의 사업 전개 내용과 매우 유사함을 알 수 있었다. The current global water market has been reshaped with a few multinational water companies, water-specialized companies, and other non-construction companies such as manufacturing and financial companies. Each has different business objectives along with the value chain of water industry. In this context, a SWOT-ANP model is proposed to prioritize strategic alternatives for a non-construction company in Korea and the result is validated through a comparison with the AHP model and real business strategies of the company examined from the recent news reports. The validation was confirmed that the company's strategies are very much similar to the priority list and the rankings of the strategic alternatives are identical with those from AHP model, while the weights are slightly changed from the weights in AHP result.

한국근현대사의 굴곡 속에서 공공 및 민간기록물이 훼손되고 유실되었다. 2007년 "공공기관의 기록물관리에 관한 법률"이 "공공기록물관리에 관한법률"로 전면 개정되면서, 민간에 소산되어 있는 주요 기록물을 파악 보존하기 위해 '국가지정기록물'을 지정하는 제도가 보강되었다. 중앙기록물관리기관에서 일정한 기준과 범위를 정하여 '국가지정기록물'을 지정하여 소장기관을 후원함으로서 공공기록물의 한계를 보완하고 한국사회의 역사상을 풍부히 하는데 기여할 것이라 기대하고 만든 제도이다. 2007년부터 2015년까지 총 14건의 기록물이 국가지정기록물로 지정되었다. 본고에서는 어떠한 기록물들이 '국가지정기록물'로 지정되었으며, 소장처들은 국가지정기록물을 어떻게 관리하고 활용해왔는지 살펴보고자 한다. 이를 통해 국가지정기록물 지정제도의 관리현황을 파악하고자 한다. 더불어 '국가지정기록물' 소장기관의 담당자를 면담하여 국가지정기록물 소장처의 기록물 관리현황과 서비스 현황 및 국가지정기록물 지정 효과를 살펴보고, 국가지정기록물 지정제도의 개선방안을 제언하고자 한다. This study is on management present and improvements on National Records Designation System. National Records Designation System is a system that supports management and preservation of changes of records designated by the government through consideration that such records are worth preserving permanently nationally among records acquired by individual or organization. This system is meaningful in a way that it established systematic foundation to hand down by informatizing historic private records which are in danger to be lost or damaged due to lack of proper care. However, compared to the number of designated records, the information that could be practically drawn from such records are limited. This triggered this study to be launched. National Archive sometimes promotes designation and management of National Designated records. Yet archival information service offering access of user to national designated records are very rare. I conducted survey and interview of managers, field research, and documentary research of 10 records holding institution that keeps national designated records currently. I considered that current management status of National Records Designation System can be figured out minutely through these research. As a result of such research, most of the records holding institutions offered display as their least archival information service. The objective of records informatization was to utilize the records. Also further plans on information service related to records and various utilization were suggested. records holding institution manager did not give positive answer on effect of designating national designated records and cooperation between National Archive. Support to National Archive only focused on preservation. For national designated records holding institution designated after 2011 were not getting proper support. In addition, National Archive's support rarely met records holding institution's need. In such circumstances, things to consider for improvements of National Records Designation System is as following. First, designation of national designated records should be based on the utilization of the record. Each records holding institution's willingness to utilize corresponding records and National Archive's ability to draw the willingness out should be considered. Also, it shouldn't be left as mere complementary policy of National Archive's selecting policy. Second, for National Records Designation System to be managed permanently, it should be changed as the system that supports enhancement of private records management. The aim should point to the direction where private can manage and preserve the records on their own. Third, There needs to be changes on the subject and process of national designated records designation. National designated record is the record that was considered valuable by the government among private records. Thus, such records should be the best one to show private field. Accordingly, records that represent contemporary society and include various states and contents should be chosen to be designated. Moreover, public discussion be formed by citizens and related professionals in order to properly select the record.

Three-dimensional flow analysis and numerical optimization methods are presented for the design of an axial-flow fan. Steady, incompressible, three-dimensional Reynolds-averaged Navier-Stokes equations are used as governing equations, and standard k- ${\varepsilon}$ turbulence model is chosen as a turbulence model. Governing equations are discretized using finite volume method. Steepest descent method, conjugate gradient method and BFGS method are compared to determine the searching directions. Golden section method and quadratic fit-sectioning method are tested for one dimensional search. Objective function is defined as a ratio of generation rate of the turbulent kinetic energy to pressure head. Two variables concerning sweep angle distribution are selected as the design variables. Performance of the final fan designed by the optimization was tested experimentally.

The flow characteristics around an elliptic cylinder with axis ratio of AR=2 located near a flat plate were investigated experimentally to study the interaction between the cylinder wake and the turbulent boundary layer. The pressure distributions on the cylinder surface and on the flat plate were measured with varying the angle of attack of the cylinder. In addition, the velocity profiles of wake behind the cylinder were measured using a hot-wire anemometry As the angle of attack increases, the location of peak pressure on the windward and leeward surfaces of the cylinder moves toward the rear and front of the cylinder, respectively. At positive angles of attack, the position of the minimum pressure on the flat plate surface is moved downstream, but it is moved upstream at negative angles of attack. With increasing the angle of attack, the vortex shedding frequency is gradually decreased and the critical angle of attack exists in terms of the gap ratio. By installing the elliptic cylinder at negative angle of attack, the turbulent boundary layer over the flat plate is disturbed more than that at positive incidence. This may be attributed to the shift of separation point on the lower surface of the cylinder due to the presence of a ground plate nearby.

In order to substitute current aluminum sabot and to increase the penetration performance of the kinetic energy projectiles, the research and development program for composites sabot has been conducted. For carbon/epoxy composites sabot, unidirectional carbon fiber reinforced epoxy prepreg was chosen and thick sectioned composites preforms with the different fiber angles along the circumferential direction of sabot were prepared by compression molding under the careful processing conditions at $150^{\circ}C$ for 1hour with $70kgf/cm^2$ curing pressure. The composites sabot demonstrated a weight reduction by approximately 30% than that of current aluminum sabot. The muzzle velocity of a kinetic energy projectile with composites sabot was measured to be about 63m/s higher than that with aluminum sabot. These results imply that the penetration performance is expected to be considerably increased when the composite sabot is applied to the kinetic energy projectiles.

In China, the enhancement of water services has become the most crucial issue confronted with the rapid urbanization and industrialization process. A huge financial gap to meet the demand for water infrastructure and need for adopting advanced operation technology precipitated the rapid growth of PPP over the last 10 years. Diverse schemes of PPP such as TOT, Divestiture, and Management Contract and Lease have been practiced. Local governments and private investors/operator have adjusted their objectives and strategies to avoid potential pitfalls behind BOT projects in China. However, current academic research outcomes do not properly reflect important issues of BOT projects or related case studies in China. This limitation has brought in the lack of assessment of important risks and success factors required for the improvement of the body of risk management. In this regard, this study uses the market analysis method to identify major schemes of PPP water projects and conducts case studies on five PPP projects to identify key risk and success factors in association with each different scheme. It is expected that the risk and success factors identified from the cases will be used as reference to Korean companies which plan to enter the Chinese water market. 중국은 지난 20년간 급속한 도시화와 산업화를 경험하면서 빠른 물수요 증가와 심각한 수질오염문제가 발생하였고 이를 해결하기 위한 효율적 물관리 방식의 도입이 절실하였다. 중앙 정부는 해결 방안 중 하나로 1995년 외국인 투자 활성화를 위해 "BOT(Build-Operate-Transfer) 통지"를 공표하고 청두 제6정수장 BOT 시범사업을 실시하였다. 또한 2002년 정부가 해외투자자/운영자의 관망분야 참여를 허용하면서 해외자본/기술 유입이 더욱 가속화 되었다. 현재 중국에서는 다양한 형태의 BOT 사업을 포함한 각종 민관협력사업(PPP)이 진행되고 있으나 현재까지의 연구 범위는 1개의 시범사업을 포함한 BOT모델 사업에 대한 위험요인 및 성공요인 도출에 제한되었다. 본 연구는 기존의 연구 한계를 극복하여 중국 PPP 프로젝트 데이터를 취합하고 주요 PPP 유형 및 사례분석을 실시하여 위험과 성공요인 및 대처방안을 도출하였다. 본 연구결과 중국 수처리 시장에서 다국적 물 기업은 외부 사업 환경의 변화에 능동적으로 대처하여 다양한 유형의 PPP 사업을 전개하고 있고 그런 유형은 지속가능한 사업모델로 자리매김하고 있다. 본 연구는 여기에서 논의한 다양한 유형별 성공 및 위험 요인들이 국내기업의 향후 중국 수처리 시장 진출에 유익한 정보로 활용되기를 기대한다.

The effect of an external acoustic excitation on the wake structure behind a circular cylinder was experimentally investigated. The sound wave was excited in the frequency range of the shear layer instability and two sound pressure levels of 114 and 120dB were used in this study. As a result, the acoustic excitation modified the wake structure by increasing the velocity fluctuation energy without changing the vortex shedding frequency. The acoustic excitation enhanced the vortex shedding process and promoted the shear layer instability. Consequently, the acoustic excitation reduced the length of the vortex formation region and decreased the base pressure. In addition, the vortex strength of vortices was increased and the width of the wake was spread out due to the acoustic excitation. When the excitation frequency was identical to the shear layer instability frequency, the effect of the external flow control on the cylinder wake was maximized. In addition, with increasing the sound pressure level, the effect of the external acoustic excitation on the wake structure increased.
