조도현,원영진,이종용 대한전자공학회 2005 電子工學會論文誌 IE (Industry electronics) Vol.42 No.3
This paper presents a design of a multi-objective controller of an inverted pendulum with polytopic model for the stabilizing regulator and tracking performances. Multi-objective controllers are designed for polytopic models by the LMI design technique with convex algorithms. It is observed that the inverted pendulum controlled by any controller designed for each polytopic model is stably restored to the vertical angle position for initial values of larger tilt anlges. 본 논문은 안정화 조절기와 추종 성능을 확보하기 위하여 폴리토프 모델를 갖는 도립진자 시스템의 다목적 제어기를 설계를 나타낸다. 꼭지점 기법을 갖는 LMI 설계 기법에 의하여 폴리토프 모델에 대한 다목적 제어기를 설계한다. 각 폴리포프 모델에 대하여 설계된 제어기에 의해 제어된 도립진자를 큰 경사각의 초기값에 대한 수직 각을 안정하게 연직 위치로 복원시키는 곳을 관찰한다.

본 논문은 전기자동차의 난방 공조에 사용되는 PTC 소자를 사용한 전기 히터 시스템의 성능 개선을 위한 연구이다. 기존의 IGBT 제어 방식의 과열과 고주파 특성에서 단점을 MOSFET의 제어로 보완설계하고 평가하였다. 또한, PTC 히터 제어를 위하여 센서 회로, ESD 보호회로를 구성하고, EMC 개선을 위한 회로설계 적용하였다. 이러한 설계를 통하여 IGBT를 사용한 경우 보다 상대적으로 저용량인 공기 가열식 히터 구현이 가능하다는 것을 보였다.
자율 주행 중 센서 전송처리를 위한 KC-CAR 알고리듬 제안

Sensor-collected data transmission processing technology is an essential technology for providing various intelligent vehicle driving services, such as autonomous driving or collision risk notification within the vehicle's remote control, and autonomous driving. In this paper, we present a routing protocol transmission processing algorithm for real-time data collected from sensors attached to automobiles for stable and fast processing speed. The proposed algorithm configures the car as a cluster head, the sensors attached inside the car as member node I, and the devices outside the vehicle as member node II. It was intended to increase the efficiency of transmission energy between sensors. It was shown that the transmission energy efficiency increased by about 19%.

본 조사는 밤나무혹벌의 생태, 특히 생활사, 발생소장 및 피해에 대하여 1961-1963년에 걸쳐 경기도, 강원도 및 충청북도에서 조사한 것이다. 1. 본 충은 년 1회 발생하며 단성생식을 한다. 2. 성충의 출현은 6월 하순부터 7월 하순이며 최성기는 7월중하순이며 일중 오전중에 많이 탈출한다. 3. 성충은 출현후 곧 아에 산란하는데 1아당 4.89개를 산란하며 1개체의 포란수는 평균 198.5개이었다. 4. 란기는 30일간이며 란은 8월말까지 부화하였다. 5. 유충기간은 8월중순부터 익년 6월 중순 까지며 용기는 6월 초순부터 7월 중순까지였다. 6. 본 충은 아에 산란 기생하며 5월 하순부터 충영을 형성하여 생장을 정지시키고 율의 결실을 없게 할 뿐만 아니라 율목을 고사시킨다. 8. 본 충은 1958년 충청북도 제천에서 처음 발생된 이래 현재에는 강원도, 경기도, 충청북도의 북반부 및 경상북도북부 일부에 분포하여 가해하고 있다. The chestnut gall wasp, Dryocosmus kuriphilus $Y^{ASUMATSU}$, has been recently distributed and chestnut trees have teen seriously damaged by this insects in Korea. However, this insect pest has not been investigated in Korea. This paper gives an account of field and Laboratory observations on the seasonal occurrence and the life history of the chestnut gall wasp, and the damage of the chestnut trees by. its insects. This study was carried out at Chungchungpukdo, Kangwon-do and Kyungi-do in Korea, from 1961 to 1963, inclusive. 1. The Chestnut gall wasp (Dryocosmus kuriphilus $Y^{ASUMATSU}$) has one generathion per year and females are only known. 2. The adult wasps were observed from late June to late July with peak of wasp emergence about early and middle July. Most of new adult wasps were coming out from, the galls in the morning rather than the afternoon. 3. Each wasp produced auerage 198.5 eggs and about 4.89 eggs was observed in each bud of the chestnut tree. 4, The egg period of wasps was about 30 days and they were hatching from July to August. 5. The larval period of wasps were from middle of August to middle of next June and pupation took places about early June to middle of July. 6. The adult wasps were ovipositing into the buds and from early May next year, galls were growing. They caused stunting of growth and no fruiting or dying of the chestnut tries. 7. The first observation of the wasp was made at Chaechun of Chungchung-pukdo in 1958. Up to 1963 this insects are distributed in Kangwon-do, Kyunggi-do, north part of Chungchung-pukdo and north part of Kyungsangpukdo

The Two-Mass Spring(TMS or Two-Inertia Resonance) system is one of the simplest models which generate a torsional vibration. In this system, it is required to design a controller achieving the control performance while suppressing the torsional vibration. In this paper, we compared and considered with the state feedback effects for the TMS system. By connecting each controller design to the state feedback control, we could predict each controller performances and decide weighting functions and parameters of LQ and $H_\infty$ controller.

<田禹治>서사의 현대적 변이와 유통방식 -영화 <전우치>를 중심으로-

Recreation of traditional narratives found in folktales and ancient novels into movies has constituted a mainstream of modern popular culture. The life force of an old story survives time and tide to reach the modern audiences, and the advancement of cinematic technology makes it possible to visualize the fantastic elements of the ancient tale. Therefore, diverse media such as animation, theater, film, television drama, and game are enacted to transform old stories into cultural contents, aggrandizing their popular status in the 21st century modern society. The film Jeonwuchi is based on the story of Jeonwuchi a historical figure from the Jeoseon period. In particular, Tale of Jeonwuchi, the original story of the film, has been well-known among the public in the form of folklore and novel: the film version successfully recreates the world of fantastic romance in which the protagonist performs brilliant exploits. The typicality of hero story, often described as a "life of hero," has been utilized as a universal way to compensate for the sense of deprivation that the public feel in reality. Jeonwuchi is loyal to the theme of the original folktale by portraying the catharsis of desire which unfolds in the criticism of unjust society, the conflict between the good and the bad, the punishment of villains, and the final triumph of the hero in the face of adversities. In the mean time, although the film version maintains the basic elements of the original story, the former also differentiates itself from the latter, showing a unique change in the plot structure. In order to embrace changing world-views in the cinematic adaptation, Jeonwuchi rearranges the series of events, catering to modern sensibility. The character of the protagonist also incarnates the 21st century type popular hero: the hero appears as a lighthearted, active, and talented man, living in a freewheeling urban life style. Moreover, sensational images are advanced to the fullest extent, capitalizing on the unique aspects of the film medium. Jeonwuchi as a visual literature holds greater potentialities to be further developed thanks to the charming motif of hero story. The multimedia upholding modern society provide continuously diversifying forms of narrative for the folk hero. Jeonwuchi on its part carries the power of sustainable narrativation. In conclusion, Jeonwuchi has a vital force to be creatively conveyed to the modern audiences through renewed adaptation and circulation.
