최재호(Choi Jae-ho) 국방부 군사편찬연구소 2015 군사 Vol.- No.96

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.

The organic yields (i.e. fraction of nuclear events resulting in organic compound formation) of the radioative neutron capture reactions of halogens in purified bromobenzene have been determined varying extraction time, at $100^{\circ}C$ for thermal effect, varying irradiation time, varying neutron flux and with additional U. V. irradiation. Among the important results are; (1) The organic yields show no remarkable fluctuations with time following neutron irradiation; (2) The organic yields show no change with thermal energy; (3) The organic yields of degassed samples are same in different length of irradiation time whereas the yields of the samples in open air appear to increase with increasing time of irradiation (4) The organic yields increase remarkably with increased neutron flux; (5) The organic yields show a sharp increase by additional U. V. irradiation after neutron irradiation.

炭化水素內에서의 Alkyl Iodides의 光分解에서 $II^{131}$과 Alkyl Iodides 間의 交換反應

The rate of exchange of I atom between alkyl iodides(ethyl or methyl iodide) and $I_2$ in n-hexane have been determined using $II^{131}$. It is found that the escape of $CH_3$ radicals from a solvent cage is faster than $C_2H_5$ radicals and that photolysis of $C_2H_5I$ is almost identical to that in the case of $CH_3I$.

The flow fields inside a molten Zn pot of continuous hot-chip galvanizing process were investigated experimentally. With varying several parameters including the strip speed Vs, flow rate Q of induction heater. scrapper location and baffle configuration, instantaneous velocity fields were measured using a PIV velocity field measurement technique. Inside the strip region, counter-clockwise rotating flow is dominant. The general flow pattern inside the strip region is nearly not influenced by the strip speed Vs, flow rate Q and the scrapper location. In the exit region, the flow separated from the moving strip due to the existence of a stabilizing roll ascends to the free surface, for the cases of no scrapper and scrapper detached form the roll. On the other hand, the ascending flow to the free surface is decreased, as the flow rate Q of induction heater increases. By installing a baffle around the uprising strip, the flow moving up to the stabilizing roll decreases. In addition, B-type baffle is better than A-type baffle in reducing speed of flow around the stabilizing rolls. However, the flow ascended to the free surface is largely influenced by changing the flow rate Q, and the scrapper location, irrespective of the baffle type.

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

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.

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.

In the present paper, a transonic mixed-flow compressor that has relatively lower frontal area than that of centrifugal compressors is discussed, and aerodynamic design as well as performance prediction are performed. Main design constraints are compressor exit Mach number of 0.3 and flow angle of 30degrees at the design point, and maximum overall compressor diameter of 177mm, that is 7.0inch. The mass flow rate of design point and pressure ratio are 1.05kg/s and 5.2:1, respectively. The aerodynamic design results show that the transonic compressor designed with forward-swept inducer and curved diffuser can have the target performance with efficiency of 75% within the given constraints. And the compressor exit flow characteristics are discussed here.
