김효중 ( Hyo Joong Kim ) 세계문학비교학회 ( 구 한국세계문학비교학회 ) 2007 世界文學比較硏究 Vol.19 No.-

This Article is a research on Choon Soo Kim`s poetic Emotion and Images based on the Christianity. To Jesus, the man in poverty should be first. Jesus as an arnachist on the basis of his anti-historical thought, because Jesus stands on the side of the poor and the weak against the rich and powerful. In Kim`s poems, Jesus appears as a character of solitary existence. Jesus is not portrayed as a historical being but as poetic reality that removes the thought of dichotomy and closes in upon our being. Kim finds the view of his poetry. the so-called Aesthetics Uselessness, in the spirit of Jesus. That the common notion which insists that labour is more worthy than play should be removed. We must recognize that the value of play is as the value of labour. Every means to that end or that ideology is always justified. Jesus endures the terrible pain of crucification to save mankind from evil. Choon-Soo Kim sees a high souled person in Jesus who opposed violence with his nonresistance. Kim thinks that the soul Jesus can overcome the untruth of history made by man. In short, Kim doesn`t trust history made by man. He writes in his poems of the dreams and realities made by the solitary existence of Jesus.

김효중,Kim, Hyojoong 한국응용곤충학회 2013 한국응용곤충학회지 Vol.52 No.4

꽃매미 날개의 형태적 변이가 지역에 따라 차이가 있는지 확인하기 위해 형태계측학 분석을 실시하였다. 꽃매미 개체는 한국, 중국, 일본 10개 지역에서 채집되었고, 꽃매미 앞날개로부터 선발된 14개의 형태계측학 형질을 분석하였다. 결과로 국내 지역 개체들은 중국 양쯔강 이남보다는 이북 지역 개체들과 형태적으로 가까웠다. 서울과 부안 개체는 상하이 개체와 형태적으로 매우 유사하였다. 점무늬의 경우 베이징 개체가 상대적으로 작았고, 중국 남부의 린안 개체가 크게 나타났다. 날개의 크기는 일본 개체가 상대적으로 큰 것으로 분석되었다. Morphometric analysis of Lycorma delicatula was performed to confirm whether local individuals had a geographical difference in their wing variations. The L. delicatula individuals were collected from 10 localities in Korea, China, and Japan, and 14 morphometric characteristics selected from the forewing were analyzed. The Korean individuals were similar to the ones from the northern area of the Yangtze River, but less similar to the others from the southern area of the Yangtze River. The individuals from Seoul and Buan were very similar to those from Shanghai. In case of wing spots, the individuals from Beijing had relatively small spots, while the ones from Linan had big spots. The Japanese individuals had a relatively large wing size.

Here I investigate what effects Operational Control Center(OCC)'s service quality may have on airline staff's job engagement. My analysis reveals that airline OCC's service quality has a meaningful effect on airline staff's service satisfaction, and that service satisfaction mediates a meaningful effect on staff's job engagement. It was suggested that improving OCC's service quality leads to higher staff's job engagement. Accordingly, I suggest methods of improving OCC's service quality. I find that the importance of contributing factors on OCC's service quality are as follows, in order of most to least important: professionalism, assurance, empathy, reliability, organizational culture, and responsiveness. The results of this study are relevant not only for airlines but also for government agencies such as the National Emergency Management Agency, the Korea Forest Service, the National Police Agency and the Korea Coast Guard that operate aircraft and must ensure aviation safety.

There are several different types of continuously variable transmission(CVT) such as toroidal drive, belt drive, hydrostatic drive, hydro-mechanical drive. The toroidal CVT is an alternative to the manual transmission, HST, power-shift gear trans-missions or other CVTs. The driver of the CVT tractor doesn't have to operate a shia lever since the CVT controller automatically controls the speed of tractor. Thus, it is much easier to operate the CVT tractor. The fuel efficiency of CVT tractor can be increased since the controller responds quickly to the change in external load on the wheel during field operation. This study was conducted to develop the hardwares and softwares for the toroidal CVT controller which control the variator and the range clutches. The hardware consisted of a measurement system, hydraulic system and computer. And the PID controller was developed using the simulation model of the CVT control system. Through the simulation, the control coefficients for the PID controller were selected. Finally, the performance of the CVT control system was evaluated by step response test and torque response test. The settling time of the CVT control system appeared to be fast enough for field operations.

다수 무인기를 이용한 시스템은 정찰, 네트워킹, 항공 촬영 등 다양한 목적으로 활용되고 있다. 이러한 시스템에서 다수 무인기로 구성된 대형을 형성하고 유지하는 것은 필수적이다. 본 논문에서는 다수 무인기의 대형을 형성하기 위한 자율화된 분산형 제어를 수행하는 알고리즘을 제안하였다. 제어명령은 근접 무인기 또는 임무 영역으로부터 서로 밀어내는 방향으로 작용하는 2차 시스템 형태의 힘을 고려하였다. 제어명령은 외부의 개입 없이 계측과 통신으로부터 획득되는 상대위치/속도를 통해 계산된다. 이는 개별 무인기들이 기준거리를 추종하도록 하며 임무영역 안에 겹치지 않고 최대한 조밀하게 배치되도록 한다. 기준거리 결정에는 채우기 문제를 풀기 위한 최적화 기법과 유사한 방식을 적용하였다. 임무영역은 형성하고자 하는 대형의 외곽선으로 정의되며 임무에 따라 유동적으로 설정될 수 있다. 제안한 알고리즘의 성능을 확인하기 위하여 수치 시뮬레이션을 수행하였다. 복잡성과 확장성을 고려한 영역에서 약 26.94초에 대형이 형성되며 약 71.91%의 채우기 밀도를 가지는 것을 확인하였다. Multiple UAV System has been used for various purposes such as reconnaissance, networking and aerial photography. In such systems, it is essential to form and maintain the formation of multiple UAVs. This paper proposes the algorithm that produces an autonomous distributed control for each vehicle for a flexible formation. This command is a repulsive force in the form of the second-order system by the nearest UAV or mission area. The algorithm uses the relative position/speed through sensing and communication for calculating the command without external intervention. The command allows each UAV to follow the reference distance and fill the mission area as densely as possible without overlapping. We determine the reference distance via optimization technique solving the packing problem. The mission area comprises the desired formation outline and can be set flexibly depending on the mission. Numerical simulation is carried out to verify the performance of the proposed algorithm under a complex and flexible environment. The formation is formed in 26.94 seconds and has a packing density of 71.91%.
