The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based o the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

컨테이너 터미널의 선석 계획을 위한 Container Crane 스케쥴링

김홍배,이해경 경성대학교 공학기술연구소 1998 공학기술연구지 Vol.5 No.-

This study considers how to schedule container cranes for the arriving vessels in a port container terminal. The container cranes are key resources in a container terminal and the throughput of container terminals are mainly affected by the efficiency of the container cranes scheduling. The container cranes scheduling are affected many factors such as calling schedule, booking prospect and so on. We developed the mathematical model for the container cranes scheduling. The objective function is composed of the waiting time of vessel's, the violation cost of calling schedule and the fixed cost of container cranes. We solved this mathematical model using the genetic algorithm and analyzed the performance of genetic algorithm. We performed many experiments with the developed genetic algorithm and found that the results of genetic algorithm was converged very fast within the 40th generation, the run time was within a few minutes. The computer program developed in this study can be applied to the real operation of a port container terminal.

金弘培 淸州大學校 1982 論文集 Vol.15 No.2

This paper discusses the analysis of Hot-Electron emission current in MOS FET using the numerical method. The discussion begins with Hot-Electron emission current Model and use the normal MOSFET and LDD (Lightly Doped Drain). The emission probability is a function of substrate doping profile, substrate voltage, gate voltage, and lattice temperature. It is shown how LDD can be used to reduce the Hot-Electron emission current.

PL(Product Liability) 예방을 위한 디자인 접근체계에 관한 연구

김홍배 한국기초조형학회 2003 기초조형학연구 Vol.4 No.1

2002년 7월 1일을 기해 우리나라에도 도입된 PL(Product Liability, 제조물책임)법은 바야흐로 소비자가 중심이 되는 선진 시장원리의 도입으로 이해할 수 있으며, 오늘날 소비자 안전을 우선시하지 않는 기업은 시장에서 존재하지 못할 수도 있는 소비자 헤게모니 시대로의 진입을 시사하고 있다. 그러나 PL법의 도입은 제품의 제조와 유통, 판매 등에 관여하는 많은 기업에게 큰 위협이 되고 있으며, 따라서 PL법의 도입에 따르는 전략적인 대응책을 시급히 마련하고 PL 예방을 위한 제품 개발체계를 정립하는 것은 현재 기업 생존에 직결되는 중요한 사안으로 부각되고 있다. PL에 대한 기업의 대응전략은 제품 개발단계에서의 결함 최소화를 통한 사전 예방이 목적인 PLP(Product Liability Prevention, 제조물책임예방)와 사고 발생시 법적분쟁 및 클레임 발생에 대한 기업의 효율적 대처가 목적인 PLD(Product Liability Defence, 제조물책임방어)로 나뉘어 진다. 본 연구는 PL법의 이해를 통해 기업이 전략적으로 PL에 대처할 수 있는 여러 가지 방안들을 조사해 보고, 특히 PLP 전략의 일환으로 제품의 PL결함을 사전에 예방하기 위한 디자인 중심의 접근방법을 고찰하였다. 본 연구에서 고찰된 디자인 접근방법은, 크게 문제해결도구와 프로세스를 중시하는 방법론(methodology)적 접근과, 거시환경 속에서의 개체간 상호작용과 관련성을 중시하는 안전(safety)에 대한 디자인 문제를 프레임워크(framework)적 관점에서 풀어야 함을 제안하였다. PL (Product Liability) which took effect from July 2002 in Korea, represents that the current market principles are consumer-oriented mainly, and without deep consideration of consumer's safety, companies could never survive in the market competition today. PL gives big threats to the companies being involved in the any part of the process of manufacturing, distribution, sales of products, indeed. It is getting more important and urgent that companies prepare strategic plans for PL and build the product development system based on PL. The strategic plans for PL are divided two categories; PLP(Product Liability Prevention) aims to eliminate or reduce product defects in the stage of product development, and PLD(Product Liability Defence) aims to manage legal issues and claims from consumers after accident occurs which is related with product defects. This paper aims to illustrate PL prevention system through research of PL cases and corporate strategies for it, and identify design approaches: Methodology-based Approach and System-based Approach. The study found that it is very important to identify design issues for product safety through the framework of integrate product design methodology and system, and the result of the study suggested a design framework model for product safety to achieve PL prevention in the stage of product development.

김진영,배성미,홍경자,라현오,김양리,강문원 한국병원약사회 1999 병원약사회지 Vol.16 No.1

In order to find out whether ceftriaxone, a third generation cephalosporin antibiotics, is used appropriately, safely and effectively, DUE study was conducted by reviewing 70 charts of patients who were treated at Kangnam St. Mary's hospital from Oct. 1997 to Nov. 1997. The DUE criteria was modified from the criteria on ceftriaxone use established by American Society of Health-System Pharmacists. As a result, 33 cases (47.2%) were met with criteria for the justification of use. The analysing process indicators including CBC, SCr were taken before the initial dose and the vital sign monitoring were relatively well documented showing the accepted levels of above 80%. On the other hand, blood sampling for the culture and sensitivity test before the initial antibiotic dose WBC Count, SCr, LFT during the therapy were in low accepted levels. As an outcome analysis, the result of blood culture after discontinuing drug were documented with accepted level of 24.3%. As a conclusion, it is suggested that above finding should be communicated to the medical staff, and an active intervention, such as feedback control system by pharmacist, also be necessary for the rational medication use.

김홍래,배길호,정경규,한성현 한국공작기계학회 2004 한국공작기계학회 춘계학술대회논문집 Vol.2004 No.-

This paper proposed trajectory tracking control of mobile robot. Trajectory tracking control scheme are real coding genetic-algorithm and back-propergation algorithm. Control scheme ability experience proposed simulation. Stable tracking control problem of mobile robots have been studied in recent years. These studies have guaranteed stability of controller, but the performance of transient state has not been guaranteed. In some situations, constant gain controller shows overshoots and oscillations. So we introduce better control scheme using Real coding Genetic Algorithm(RCGA) and neural network. Using RCGA, we can find proper gains in several situations and these gains are generalized by neural network. The generalization power of neural network will give proper gain in untrained situation. Performance of proposed controller will verify numerical simulations and the results show better performance than constant gain controller.

The purpose of this study was to investigate the balancing training effect on weight bearing ratio and postural sway on the unstable surface for the CVA patients with balance disability. The inclusion criteria were walking independently 20m distances. Eighteen subjects, 4 with right and 14 with left hemiplegic patients were participated in this study. The range of age was from 35 to 75 and the duration from onset time was from 1 to 38 months. The intervention program including balancing training that they were introduced for 10 minutes every other day during 12 weeks to experimental group, and general therapeutic exercise to control group. The result of this study were as following: 1. The balancing training on the unstable surface showed that the postural sway of left/right distribution would appear more effective on sitting with eyes opened. 2. The balancing training on the unstable surface showed that the postural sway of forward/rear distribution, left/right distribution and distance would appear more effective on standing with eyes opened. 3. The balancing training on unstable surface would increase more effective on the weight-bearing ratio of left/right difference and frequency. 4. The balancing training on unstable surface was statistical significant on the postural sway of left/right distribution and area in experimental group, and it was statistical significant on the postural sway of forward/rear distribution, left/right distribution and distance in control group, too.
