  • The punose of this paper is to introduce the comprehensive CAM system (called PosCAM) supporting various function requested from shop floor operators. PosCAM is comported of two subsystems (PosCAM I and PosCAM II) which are designed to make up for the contemporary CAD/CAM systems. PosCAM I is mainly for : a) verifying the part programs written in both custom macros and standard G-codes, b) enhancing machining productivity and quality with built-in cutting conditions and feedrate optimization algorithm. PosCAM II is for : a) efficiently managing the numerous part programs and tool data stored in CNC memory, and b) integratively controlling and monitoring various CNCs from the control center through RS-422 with DNC 2 protocol. The developed systems have been tested via various experiments, and can be Applied for the industrial CNC machine shop as a means for enhancing productivity. The PosCAM system has been implemented and successfully used in the Machine Shop Department of PosCAM since march 1998.

  • 컴퓨터의 발전에 따라 식당운영 기법도 많은 영향을 받았다. 오늘날 이러한 많은 변화 중에서 여러 가지의 긍정적인 혜택을 찾아볼 수 있는데 그 중에는 영양분석, 회계, 구매등의 영역에서 여러 가지 발전이 그것이라 할 수 있다. 그러나 모든 컴퓨터 시스템(POS)이 동일한 기능과 잠재성을 가지고 혜택을 주는 것은 아니며 POS 시스템의 구조를 이해하고 발전가능성을 예견하는 것은 매우 중요한 사안이다. 최근의 컴퓨터 환경은 무척 빨리 발전하고 있는데 식당의 운영자에게 중요한 점은 올바른 POS 시스템을 구입하는 것이다. 우리는 이 연구를 통해서 식당의 POS 시스템에 관하여 이해를 하고 향후의 발전 방향을 예측할 수 있을 것이다.

  • In this paper, we discuss the effectiveness of information system such as POS(point of sale) and PDS(POS data service) to the government-supported small retail shop called nadle shop. Also, the functional requirements for PDS implementation are examined. Introduction of information system to small retail shop is necessary for achieving good - but a little impact on - management performance. For the empirical study, the survey results for POS utilization and management performance for the nadle shops supported from 2010 to the first half of 2011 are analyzed. Consequently, information system doesn't give direct effect on producing management performance. However, no doubt it contribute service quality and satisfaction to the customers and provides refined information to be useful to the owners.

  • Recently, the small scale photovoltaic (PV) electronic devices are drawing attention as the upcoming PV generation system. The PV system is commonly used in small scale PV applications such as LED lighting and cell phone. This paper proposes photovoltaic output sensorless (POS) maximum power point tracking (MPPT) control for a small scale charging system of PV-nickel metal hydride battery using field-programmable gate array (FPGA) controller. A converter is connected to a small scale PV cell and battery, and performs the POS MPPT at the battery terminal current instead of being at the PV cell output voltage and current. The FPGA controller and converter operate based on POS MPPT method. The experimental results show that the nickel metal hydride battery is charged by the maximum PV output power.

  • This study is to investigate the current use of POS system in Korean clothing industry, so that we can make suggestions for better use of it. We interviewd companies using POS systems as well as EAN Korea which is in charge of POS data processing. As a results. we found out that standard KAN code has severe difficulties to cope with the diversity of the information which is necessary in clothing industry. Therefore we are making some suggestions to use KAN code as a recognizing code for more structured master data file for extremely diverse clothing items.

  • 본 논문에서는 드래그 UI를 이용한 POS(Point of Sales) 시스템을 제안한다. 현재 시중에서 판매되는 POS들은 많은 현업자들이 불편함을 요구하고 있는 상태이다. 실제 시장조사 결과 10곳중 8곳은 기능은 많지만 사용이 어렵다고 불편함을 호소했다. 그래서 우리는 드래그 기능을 UI를 통한 가게 실제 모습을 반영할 수 있고, 주문, 메뉴선택 등 사용이 편리한 드래그UI 환경의 POS 시스템을 생각해 보았다.
