          저전력 주차 안내 시스템 설계

          박주용(Ju-Yong Park),임형규(Hyeong-giu Lim) 한국엔터테인먼트산업학회 2011 한국엔터테인먼트산업학회논문지 Vol.5 No.1

          주차안내 시스템은 주차장에서 주차정보를 제공하여 운전자에게 주차 편리성을 제공한다. 동시에 다수의 센서, 디스플레이와 제어모듈을 이용하여 아주 소량의 전기 에너지 만을 소모한다. 녹색 빌딩 설계의 요구가 점차 증가함에 따라 주차관리 시스템의 운용 전력 감축 문제가 이수화 되고 있다. 본 논문에서는 주차 관리 시스템의 감지기와 디스플레이 장치의 설계와 소비전력 감축의 결과를 제시한다. 이 시스템은 무선 Park Tile 과 Park Disk를 사용하여 전력소비를 감축 시키고, 여러 개의 주차공간 감지기와 자동차 카운터, 정보 디스플레이 장치, 안내 터미널과 제어장치로 구성되어 있다. 그리고 시스템 구조설계와 통신망 설계, 주차정보 서비스 시나리오 설계, .배터리 수명 제어, 운영 전력 평가 등이 수행되었다. 주차장당 운영전력은 0.4W로 평가 되었으며, 이는 기존 시스템의 17%정도 이고 매년 유지비는 기존 시스템에 비해 43%에 해당된다. The parking guidance system can increase driver’s convenience with detailed parking information service in the parking lot. At the same time, parking guidance system consumes non-negligible electrical energy with large amount of sensors, displays and control modules. With the increase in the demand for green and sustainable building design all over the world, it becomes a meaningful issue for parking guidance system to reduce operating power. This paper presents the preliminary design and estimated results of a parking guidance system which is optimized to reduce the power consumption mainly on detectors and displays. The system design is based on pre-developed wireless parking detectors, Park Tile and Park Disk. The system has a number of parking space detectors, vehicle count detectors, information displays, guidance terminals and other control units. We have performed system architecture design, communication network design, parking information service scenario planning, battery life regulation and at last operating power estimation. The estimated operating power was 0.4 watt per parking-slot, which is 17% of traditional systems. The estimated annual maintain cost was 43% of traditional systems.

          표적 주변의 방해자극이 표적에 대한 의식적 반응에 미치는 영향

          박주용(Park Ju Yong),김정훈(Kim Jeong Hun) 한국심리학회 2003 한국심리학회지 인지 및 생물 Vol.15 No.4

          Prinzmetal 등(1998)은 대상에 주의가 보다 많이 주어지면 대상의 정체에 대한 불확실성이 감소하는 까닭에 반응의 변산이 줄어들어 대상이 보다 선명히 지각된다고 주장하였다. 그러나, 김정훈과 박주용(2002)은 복합 자극을 사용한 연구에서, Prinzmetal 등의 발견과는 달리, 주의로 인해 반응의 변산 뿐만 아니라 평균에도 변화가 일어남을 발견하였다. 본 연구는, 표적 자극 주변에 방해자극을 제시하는 선택적 주의 상황에서, 주의의 현상학적 효과를 조사하였다. 실험 결과, 김정훈과 박주용의 결과와 일관된 결과를 얻었다. 즉, 선택적 주의 상황에서, 주의는 반응의 변산과 반응 평균에서 변화를 초래하였다. 이 결과가 주의의 현상학에 시사하는 점이 논의되었다. It has been claimed by Prinzmetal et al. (1998) that the phenomenal vividness of an attended object resulted from the reduced variability of percepts, not from a representational change. Using a compound stimulus, however, Kim and Park (2002) recently found that, contrary to Prinzmetal et al., the change in the degree of attention accompanies a mean shift as well as the reduced variability of response. The present study examined the phenomenology of attention in a selective attention task with distractors around a target. Again, we found the same pattern of result with Kim & Park: Increase in attention resulted in the reduction of the mean error and the response variability. The implication of the result on the phenomenology of attention was discussed.

          유전정보 64 Trigram Codon의 표준 [UC;AG] 수직 블록 Code

          박주용,이성국,이문호,Park, Ju-Yong,Lee, Sung-Kook,Lee, Moon-Ho 한국인터넷방송통신학회 2016 한국인터넷방송통신학회 논문지 Vol.16 No.6

          본 논문에서는 유전정보 DNA 표준 코드인 [UC;AG]를 64괘로 분석했다. 인간의 유전정보를 담고 있는 DNA는 인산과 당에 A(아데닌) C(시토신) G(구아닌) T(티민) 등 네 종류의 염기가 30억쌍 이어 붙여진 형태이다. DNA 표준 코드를 64괘로 나타내고, 이 코드를 Kronecker product를 이용하여 $16{\times}4$행렬로 나타냈다. 이 $16{\times}4$ 행렬은 이중나선의 중복성을 가지고 있으며, 이 중복성을 제거하면 RNA코드 $4{\times}4$ 행렬을 얻는다. $16{\times}4$행렬은 Kronecker product를 이용하여 소 행렬로 분해되었다. DNA 이중나선을 행렬로 표시하고 유전정보 괘 배열 코드를 분석하였으며 그 예를 예 5, 6에 나타냈다. In this paper, we analyze the [UC;AG] code which is genetic information standard DNA code, with 64 trigram. DNA which contains human genetic information, is a shape of adding three billion pairs of four bases which are A(adenine), C(cytosine), G(guanine) and T(thymine) to phosphoric acid and glucose. We present standard DNA code to 64 trigram which is $64{\times}4$ matrix with Kronecker product. This $64{\times}4$ matrix has double helix duplex property, and we can get the $4{\times}4$ matrix RNA code by removing the duplex of it. We present the DNA double helix to matrices and analysis the trigram array code of genetic information and the examples of it are presented in example 5, 6.

          조선소 판넬라인의 최적 생산계획 수립을 위한 생산 시뮬레이션 연구

          박주용,김세환,최우현,Park, Ju-Yong,Kim, Se-Hwan,Choi, Woo-Hyun 대한용접접합학회 2006 대한용접·접합학회지 Vol.24 No.5

          Panel line is an important process occupying the largest work amount in shipbuilding. In this research product simulation has been carried out to establish the optimal production scheduling. For this purpose a web-based panel line simulator was developed using an object modeling technology and C# language. The balance of work-load and increase in the productivity by the improvement of production facilities and process are the key factors for a good scheduling. In this study SPRT(Shortest Remaining Process Time) rule was applied for the work-load balancing and a good result achieved. To increase the productivity in the stiffener welding stage which is a bottleneck; process, more welding heads and higher welding speed were tested using the developed simulator. The simulation results showed that either more welding head or higher welding speed decreased the total work time. Use of both, however, deteriorated the productivity because of the bottleneck in the following stage. This result points out that the improvement of production facilities and/or process should be evaluated with their influences on the leading and following processing stage.

          H-beam 절단용 다관절 로봇의 절단작업영역 설정에 관한 연구

          박주용,이용구,Park, Ju-Yong,Lee, Yong-Gu 대한용접접합학회 2009 대한용접·접합학회지 Vol.27 No.6

          This study aims for determination of cutting work envelope of an articular robot for H-beam cutting. The robot has its own work envelope. The cutting of piece with groove requires the specific position of the torch which contracts the work envelope. This study suggested the new method to determine the cutting work envelope for this case. The method simplified the problem by use of the combination of inverse kinematics and forward kinematics. The method was used for cutting the H-beam with groove. The cutting work envelope was determined easily. The result was verified by 3D simulation system which implements the articular robot with 6 axes and the H-beam in the virtual shop.

          Welding work in pre-erection or erection stage of shipbuilding construction to be carried out in flat and vertical upward position mostly and Electrogas welding(EGW) is actively applied especially for vertical butt joint of thicker steel plate recently. In this study considered how to develope and improve mechanical properties of weld metal and HAZ in high heat input welding processes such as EGW and Electroslag welding(ESW) with its welding equipment in order to extend the application range to the longitudinal members and hatch coaming parts of container ship. Some components of welding system and parameters were modified to get the faster travel speed and reduce weld heat input, and also by adding additional filler rods or tubes increase the amount of deposited weld metal. With the test get some good date can apply to actual fabrication work and recommend items to manufacture welding materials make better. Above all things it's a fruition that to prepare the possibility of application of ESW to shipbuilding construction which fill up the gap of stoppage days of more than 20 years.

          시뮬레이션 기법에 기초한 근골격계 질환 감소를 위한 용접자세 분석

          박주용,김동준,장성록,송창섭,Park, Ju-Yong,Kim, Dong-Joon,Chang, Seong-Rok,Song, Chang-Sub 대한용접접합학회 2007 대한용접·접합학회지 Vol.25 No.4

          The industrial disaster caused by a work-related disease like a Musculoskeletal Disorders(MSDs) becomes a big social problem and increases rapidly. This leads to the degradation of the labor desire and the productivity. Welding work belongs to the work with a high intensity. This paper aims to analyze the welding work in the various positions from a view-point of the burden of the human musculoskeletal system and to propose the desired position with lower burden. For this purpose the real welding work was observed in the shipyard and analyzed using the RULA method, a powerful ergonomics tool. The 3-dimensional simulation model fur this work was also developed. In this model, ergonomics human model and welding work environment were built. This model was verified through the comparison to the real work. This paper showed that the improvement of welding position by changing the location of a stool and using some auxiliary tool can reduce the work intensity remarkably and lead to the decrease of MSDs.
