Each LCD TFT panel requires a power supply IC on the panel board. The IC provides the power rails for the timing controller, source and gated driver IC and others. The industry trend moves towards higher integrated devices. The challenge for the panel manufacturer is the development and implementation of such an IC in cooperation with the semiconductor supplier. If not done carefully the solution will not reduce the overall solution cost or can't provide the expected performance and reliability. This paper discusses the key considerations to successfully develop and integrate a highly integrated LCD bias IC into the system.

In practical etching process, etch ant is sprayed on the metal-deposited panel through nozzles collectively connected to the manifold and that panel is usually composed of many PCB(printed circuit board)'s. The etching uniformity, the difference between individual PCB's on the same panel, has become one of most important features of etching process. In this paper, the prediction of nozzle trajectory has been performed by the combination of algebraic formula and numerical simulation. With the pre-determined geometrical factors of nozzle distribution, the trajectories of individual nozzles were predicted with the change of process operational factors such as panel speed, nozzle swing frequency and so on. As results, two dimensional distribution of impulsive force of etchant spray which could be considered as a key factor determining the etching performance have been successfully obtained. Though only qualitative prediction of etching uniformity have been predicted by the process developed in this study, the expansion to the quantitative prediction of etching uniformity is expected to be apparent by this study.

공장자동화는 국제사회 속에서 살아 남기 위한 필수 요건이 되었다. 값싼 인건비를 무기로 제품 경쟁에 뛰어 들고 있는 주변국가와 경쟁하기 위해서는 인건비 절감과 품질 향상이 필수적이다. 본 논문은 POS용 키보드의 생산공정 중에서 조립된 키보드 칼라 라벨을 자동 검사하는 시스템 개발을 최종목표로 하였다. 현재, 산업용으로 폭 넓게 사용되고 있는 머신 비전 측정시스템은 흑백의 영상과 비교적 간단한 물체에 초점을 맞추고 있다. 그러나, Fig.1의 POS용 키보드는 일반 컴퓨터용 키보드와는 달리 각각의 키가 칼라 라벨로 되어있기 때문에 기존의 흑백 머신 비전 시스템으로 자동화를 구축하기는 힘들다.(중략)

In this research, a vision system for detecting tool breakage which is hardly detected by such indirect in-process measurement method as acoustic emission, cutting torque and motor current was developed and embedded into a PC-NC system. The vision system consists of CMOS image sensors, a slit beam laser generator and an image grabber board. Slit beam laser was emitted on the tool surface to separate the tool geometry well from the various obstacles surrounding the tool. An image of tool is captured through two steps of signal processing, that is, median filtering and thresholding and then the tool is estimated normal or broken by use of change of the centroid of the captured image. An air curtain made by the jetting high-pressure air in front of the lens was devised to prevent the vision system from being contaminated by scattered coolant, cutting chips in cutting process. To embed the vision system to a Siemens PC-NC controller 840D NC, an HMI(Human Machine Interface) program was developed under the Windows 95 operating system of MMC103. The developed HMI is placed in a sub window of the main window of 840D and this program can be activated or deactivated either by a soft key on the operating panel or M codes in the NC part program. As the tool breakage is detected, the HMI program emit a command for automatic tool change or send alarm to the NC kernel. Evaluation test in a high speed tapping center showed the developed system was successful in detection of the small-radius tool breakage.

본 연구는 감각-운동 통합의 관점에서 다양한 시각 자극에 의하여 생체 내에 입력된 각기 다른 감각 정보가 운동 기능에 미치는 영향을 정량적으로 분석하기 위하여 수행되었다. 특히 보색 관계의 시각 자극이 이에 대한 운동의 반응시간에 어떠한 영향을 주는지에 관심을 두었다. 실험은 20세에서 25세 사이의 20대 성인 남녀 각각 10명을 대상으로 자체 제작한 방음 암실에서 수행하였다. 실험 장치는 디스플레이 판넬, 시각 자극을 위한 고휘도 LED 그리고 자극에 대한 반응시간 검출을 위한 키보드 스위치로 구성하였다. 지금까지의 많은 연구들은 감각 정보의 차이가 인식에 미치는 영향에 대한 평가나 색채 자극에 의한 감각 수용기의 반응의 강도의 차이를 연구하는데 머무르고 있으며 색채 환경에서의 감각-운동 협응에 대한 연구는 미흡한 실정이다. 따라서 본 실험에서는 다양한 시각 자극 환경에서 운동의 반응 시간을 계측함으로써 감각과 운동의 관계를 정량적으로 분석하였다. 그 결과 보색 관계의 시각 자극에 대한 반응시간이 동일한 색채 환경 하에서의 반응시간 보다 빠르고 동일 색채 자극 환경에서는 빛의 파장의 크기에 반비례하여 반응속도가 나타나는 결과를 얻었으며 통계적 분석(p<0.05)을 통해서 유의성도 검증되었다.

SoC(System on Chip) 기술은 높은 융통성을 제공하므로 실장제어 분야에서 널리 활용되고 있다. 실장제어 시스템은 소프트웨어와 하드웨어를 동시에 개발하여야 하므로 많은 시간과 비용이 소요된다. 이러한 설계시간과 비용을 줄이기 위해 고급언어 컴파일러에 적합한 명령어 세트를 가지는 마이크로프로세서가 요구된다. 또한 FPGA(Field Programmable Gate Array)에 의한 설계검증이 가능해야 한다. 본 논문에서는 소형 실장제어 시스템에 적합한 EISC(Extendable Instruction Set Computer) 구조에 기반한 16 비트 FPGA 마이크로프로세서인 EISC16을 제안한다. 제안한 EISC16은 짧은 길이의 오프셋과 작은 즉치값을 가진 16 비트 고정 길이 명령어 세트를 가진다. 그리고 16 비트 오프셋과 즉치 값은 확장 레지스터와 확장 플래그를 사용하여 확장한다. 또한, IBM-PC와 SUN 워크스테이션 상에서 C/C++ 컴파일러 빛 응용 소프트웨어를 설계하였다. 기존 16 비트 마이크로프로세서들의 C/C++ 컴파일러를 만들고 표준 라이브러리의 목적 코드를 생성하여 크기를 비교한 결과 제안한 EISC16의 코드 밀도가 높음을 확인하였다. 제안한 EISC16은 Xilinx의 Vertex XCV300 FPGA에서 RTL 레벨 VHDL로 설계하여 약 6,000 게이트로 합성되었다. EISC16은 ROM, RAM, LED/LCD 판넬, 주기 타이머, 입력 키 패드, 그리고 RS-232C 제어기로 구성한 테스트 보드에서 동작을 검증하였다. EISCl6은 7MHz에서 정상적으로 동작하였다.

As all aspects of international activity have kept growing in good transaction, transnational investments, joint ventures, and the licensing of intellectual property, it is inevitable for disputes to increase across national frontiers. International disputes can be settled by arbitration and ADR. In the situation presented in the paper, any dispute shall be finalized by arbitration and conciliation in the Gaeseong Industrial Complex. Inter-Korean Commercial Arbitration in the Gaeseong Industrial Complex has become the principal method of resolving disputes in trade, commerce, and investment in accordance with the "Agreement on South-North Commercial Dispute Settlement Procedures," "Agreement on Organization and Operation of Inter-Korean Commercial Arbitration Committee," and the Annexed Agreement on "Organization and Operation of Inter-Korean Commercial Arbitration Committee" (2013). But the follow-up measures of the said agreements have not been fulfilled. Some prerequisite measures of the Inter-Korean commercial arbitration must be satisfied. In order to proceed with arbitration and conciliation in the Gaeseong Industrial Complex, we need to ask the following: Does the status of an arbitrational matter? Should an agreement to arbitrate contain a choice of law clause? Should one provide for one arbitrator or three? How should the arbitrators be selected? What is the relation between party-appointed arbitrators and the presiding arbitrator (neutral arbitrator)? Do arbitrators compromise more than the litigation? Can conciliation be combined with arbitration? To execute the enactment of arbitration regulations, the contents of the Arbitration Rules of the Korean Commercial Arbitration Board (South) and the Korea International Trade Arbitration Committee (North), together with the Korean Arbitration Act and External Arbitration Act of North Korea and the UNCITRAL Model Arbitration Law and UNCITRAL l Arbitration Rules are reflected in the Rules. There are many aspects of the Inter-Korean Commercial Arbitration. It is essential to understand key elements; namely, the arbitration agreement, appointment of arbitrator, arbitral proceeding and arbitral award, and enforcement and setting aside of arbitral award. This research deals with five chapters. Chapter 1 provides the introduction. Chapter 2 deals with trade volume between South and North Korea and the kinds of dispute in Gaeseong. Chapter 3 addresses contents and follow-up measures of the agreement on the "South-North Commercial Dispute Settlement Procedures," "Agreement on Organization and Operation of Inter-Korean Commercial Arbitration Committee," and the Annexed Agreement on "Organization and Operation of Inter-Korean Commercial Arbitration Committee" (2013). Chapter 4 features the problems and tasks of the pertinent agreements. Chapter 5 gives the conclusion. Enabling parties to find an amicable solution to the dispute in the Gaeseong Industrial Complex can lead to a useful and appropriate framework either through direct negotiation or by resorting to conciliation or mediation in accordance with pertinent agreements and follow-up measures contained in the agreements.
