The weather FAX machine is the one of necessary of safety navigation for ship. which is the machine which make the weather image by the receiving radio signal which is modulated using FSK method and transmitted on air by coast station. after Coast station scan the weather image and broadcast the image with black dot to 1500Hz and white dot to 2300Hz using FSK modulation. This paper implement weather fax machine using only general IBM-PC by software. By using IBM-PC we can make some good functions like print, edit, save etc. The modulated signal from SSB go into RS232C port via photo coupler not to give damage to PC. by using Timer Interrupt and RS232C serial interrupt, we can measure signal frequency and remake weather image. This paper use only IBM-PC with general SSB receiver which is widely spread on the ship. so this is very economic and possible to implement mutifunctions.

This literature review explores artificial intelligence (AI) technology trends and IBM Watson health and medical references. This study explains how healthcare will be changed by the evolution of AI technology, and also summarizes key technologies in AI, specifically the technology of IBM Watson. We look at this issue from the perspective of 'information overload,' in that medical literature doubles every three years, with approximately 700,000 new scientific articles being published every year, in addition to the explosion of patient data. Estimates are also forecasting a shortage of oncologists, with the demand expected to grow by 42%. Due to this projected shortage, physicians won't likely be able to explore the best treatment options for patients in clinical trials. This issue can be addressed by the AI Watson motivation to solve healthcare industry issues. In addition, the Watson Oncology solution is reviewed from the end user interface point of view. This study also investigates global company platform business to explain how AI and machine learning technology are expanding in the market with use cases. It emphasizes ecosystem partner business models that can support startup and venture businesses including healthcare models. Finally, we identify a need for healthcare company partnerships to be reviewed from the aspect of solution transformation. AI and Watson will change a lot in the healthcare business. This study addresses what we need to prepare for AI, Cognitive Era those are understanding of AI innovation, Cloud Platform business, the importance of data sets, and needs for further enhancement in our knowledge base.

Scaling of the gate stack has been one of the major contributors to the performance enhancement of CMOSFET devices in past technology generations. The scalability of gate stack has diminished in recent years and alternative gate stack technology such as metal electrode and high-k dielectrics has been intensively studied during the last decade. Tody the performance of high-k dielectrics almost matches that of conventional $SiO_2-based$ gate dielectrics. However, many technical challenges remain to be resolved before alternative gate stacks can be introduced into mainstream technology. This paper reviews the research in alternative gate stack technologies to provide insights for future research.

In case there are many points to be measured in the field, conventional measuring system requires a lot of manpower and is liable to miss applying the timely countermeasure because processing and analyzing the data obtained also takes much time. Therefore the purpose of this paper is focused on removing the above defects by introducing automatic multi-point measuring system by use of IBM-PC or the compatibles easily at hand nowadays. Principal components of the system is composed of control box, A/D converter. 32 channel 4 wire switch boxes and strain amplifier. An application software was developed for multi point measurement system in order to efficiently evaluate the stability of the structures such as retaining walls.

The Immersed boundary method(IBM) is one of CFD techniques which can simulate flow field around complex objectives using simple Cartesian grid system. In the previous studies the IBM has mostly been implemented to fractional step method based Navier-Stokes solvers. In these cases, pressure buildup near IB was found to occur when linear interpolation and stadard mass conservation is used and the interpolation scheme became complicated when higher order of interpolation is adopted. In this study, we implement the IBM to an incompressible Navier-Stokes solver which uses SIMPLE algorithm. Bi-linear and quadratic interpolation equations were formulated by using only geometric information of boundary to reconstruct velocities near IB. Flow around 2D circular cylinder at Re=40 and 100 was solved by using these formulations. It was found that the pressure buildup was not observed even when the bi-linear interpolation was adopted. The use of quadratic interpolation made the predicted aerodynamic forces in good agreement with those of previous studies.

Although the use of NC machine is increasing in modern industry, unfamiliarities of the NC program syntax do not allow us to program it easily. So, automatic programming systems, such as APT, COMPACT, CL, were developed to help the uninitiated to write NC program easily. In this research, Korean Automatic Programming System for 2-axis NC lathe is developed, by which NC program is easily programmed using Korean letters. In addition, Graphic Debugger for 2-axis NC lathe is developed for debugging the NC program error and animating the cutting process. The above systems are run on the IBM-PC/XT.

ESP는 Effective System Performance의 약자로 NERSC에서 개발한 HPC 시스템에 대한 새로운 성능 측정 기준이다. 기존 HPC 시스템에서는 주로 성능 측정의 대상으로 시스템[프로세서]의 계산 성능에 주안점을 두었지만 시스템의 효율성은 무시되는 경향이 있었다. ESP는 실제 운영환경에서 배치 작업 스케줄러 및 병렬 작업 환경에 영향을 받는 시스템 효율성(ESP:Effective System Performance)을 측정하는 데 주안점을 두고 있다. KISTI 슈퍼컴퓨팅센터는 2003년 7월 국내 최고 성능의 슈퍼컴퓨터인 IBM p690+ 시스템의 도입을 완료하고 ESP를 사용하여 배치 작업 스케줄러인 LoadLeveler의 스케줄링 알고리즘에 따른 시스템 효율성 벤치마크를 수행하였다. 이 벤치마크를 통해서 효율적인 시스템 자원 활용을 위한 작업 스케줄링 알고리즘의 적용 근거를 마련하게 되었다.

This paper deals with expert system for power system fault restoration and accompanying numerical data processing. Nowadays, expert system which is a branch or artificial intelligence expands its application area to many fields. And it requires computer language for A.I. to be versatile. Expert system for power system handles numerous numerical data and language for A.I. has its deficiency in numerical data processing. However some recent version of the A.I. language rind ways of overcoming this dilemma by giving the way or linking conventional algorithmic languages to them. This study presents numerical data processing routines described in Turbo prolog which is run in IBM PC and linking numerical data processing routines written in Turbo C to Turbo prolog.

NP Forum에서는 다양한 밴더의 네트워크 프로세서와 스위치 패브릭간에 물리적 인터페이스를 제공하기 위해 CSIX-L1(Common Switch Interface-Level 1 )인터페이스를 표준화하였다. IBM 네트워크 프로세서는 MPLS 및 VPN, VLAN, Security, Ipv6와 같은 다양한 어플리케이션과 TBI. SMII CMII. POS bus등 다양한 가입자 인터페이스를 지원하며, L2 기 반에서 2.5Gbps 이상의 패킷 처리를 수행하기 때문에 많은 시스템에 사용된다. 그러나 IBM네트워크 프로세서는 스위치 인터페이스로 DASL인터페이스를 사용한다. 따라서 DASL인 터페이스와 CSIX-L1 인터페이스를 정합하기 위해서는 IBM UDASL칩을 이용해 DASL인 터페이스를 UTOPIA-L3인터페이스로 변환해야 하며, 이것을 다시 CSIX-L1인터페이스로 변환해야 한다. 따라서 본 논문에서는 UTOPIA-L3인터페이스 패킷과 CSIX-L1인터페이스 프레임을 상호 변환하는 모듈을 설계하였으며, 32비트 데이터 버스와 최대 125MHz로클록을 사용해 최대 4Gbps의 패킷처리를 제공하도록 구현하였다. 또한 스위치 패브릭의 특정 포트에서 과잉 트래픽 전달로 인해 발생할 수 있는 블로킹을 방지하기 위해 네트워크 프로세서에게 3개의 Priority／최대 64개 포트수의 VOQ(Virtual Output Queue)를 제공하는 기법에 대해서 기술한다.

선박의 안전한 항해를 위해서 필수 장비 중 하나인 기상 팩스 장비는 연안국에서 FSK 방식으로 변조된 무선 주파수를 통해서 보내는 기상도를 선박에서 수신하여 이미지화 하는 장비이다. 연안국에서는 기상도를 스캔 한 후에 중심 주파수를 1900Hz로 하고, 흑점을 1500Hz, 백점을 2300Hz 신호로 FSK 변조하여 방송하면 선박에서 이 신호를 수신한다. 따라서 현재는 기상 팩스를 받기 위해서는 기상 팩스 장비가 필요하다. 본 논문에서는 선박에 일반적으로 설치되어 있는 IBM-PC를 이용하여 소프트웨어만을 사용하여 기존의 기상 팩스 장비가 가지고 있는 모든 기능을 구현하고, 기상도의 출력, 편집, 저장 기능을 추가로 설계 및 구현하였다. IBM-PC에서는 RS-232C 보트를 통해 수신된 신호를 Timer Interrupt와 Serial Interrupt를 사용하여 이미지화 하고 주파수를 선택할 수 있게 하고, 실시간 처리 등을 소프트웨어적으로 가능하게 하였다. IBM-PC를 사용함으로 기상도의 수신 및 상태를 개선하는 이미지의 보정이 가능하며, 저장 후 처리가 용이하고, 별도의 기상 팩스 장비를 구입할 필요가 없는 경제적인 기상 팩스 시스템이다.
