원양어선을 보유한 회사에서 조업 중인 어선의 항해정보를 파악하기 위해 기존의 수작업에 의한 항해 현황판을 개선할 필요가 있다. 본 논문에서는 인터넷에 연결된 PC 또는 DID(Digital-Information Display)를 통해 선박 항해 위경도 표시 및 어획량 등 각종 항해 정보를 지도기반에서 visual하게 display하도록 설계한다. DB에 저장된 항해중인 37척의 원양어선 항해정보를 Flash 기술 기반의 RIA(rich Internet application)를 통해 역동적으로 화면구현이 가능한 Web Application 구축에 중점을 두었다. 다수의 어선상태를 한 화면에서 실시간으로 파악할 수 있기 때문에 항해정보를 모니터링하고, 의사결정을 신속히 가능하게 함으로 운영자 및 사용자에게 정보사용의 만족도를 높일 수 있었다.

소프트웨어 공학 측면에서 웹 기반 프로젝트는 상당히 비효율적인 분야이다. 웹 기반 시스템을 개발하기 위해서는 사용자 인터페이스 디자이너가 먼저 화면 레이아웃을 설계한 후 그 화면의 레이아웃 소스를 가지고 다시 비즈니스 로직 개발자가 코딩을 하여 프로젝트를 완성한다. 유지 보수를 하는 경우에도 이와 비슷한 형태로 작업이 진행된다. 이러한 웹 기반의 소프트웨어 개발 방법은 JSP의 태그 라이브러리와 같은 다양한 형태로 제안되었으나 실제로 적용하는데 여러 가지 문제점이 있으며 기존의 C/S 기반의 소프트웨어 개발에 비해 생산성 측면에서도 매우 좋지 않다. 본 논문에서 제안한 웹 폼 시스템은 기존에 제안된 방법들이 해결하지 못한 사용자 인터페이스 디자인과 비즈니스 로직을 분리하여 웹 기반 소프트웨어의 개발 생산성을 향상시킬 수 있는 방안을 제시하였다.

In this paper, the fire engine pump is controlled and monitored by the AJAX (Asynchronous Javascript and Xml) in the web server. The embedded system with built-in system having a processor and a memory of high performance occurs many problems in transmitting the large amount of data in real time through the web server. The AJAX is different from HTML (Hyper Text Makeup Language) with java script technology and can make RIA (Rich Internet Application). It process the necessary data by using asynchronous and it take advantage of usefulness, accessibility, a fast response time. Using AJAX can build up web server with real time and monitoring that fire engine pump status, check processing pump memory in the event of fire, also remotely monitors can do. The web server system can control the fire engine pump as like the black box. The experimental results show the effectiveness and commercialize possibility.

Mobile phones are evolving into a platform for internet access. In order to display web pages in handsets, WVGA and around 3-inch displays are strongly recommended. Low power consumption, compactness and narrow boarder area are essential. The general requirements for WVGA solution and the design factors to reduce the power consumption and boarder area discussed.

Ink transfer process from the printing roll to the moving web was investigated using a CFD technique for the application in R2R printed electronics. In line with the requirement that the web handling speed needs to be increased further for the cost competitiveness, the effects of web moving velocity with relatively complex roll patterns were analyzed. To make the present analysis more realistic, the numerical geometry and the ink properties were selected to match those of the real printing production system. Our numerical results showed that both web handling speed and complex printing-roll patterns influenced the shape of the transferred ink. As the web moving speed approaches towards 30mpm, a significant distortion of the shape of the transferred ink occurred. In the range of pattern width smaller than 100 microns, a phase distortion was also found to occur in all the printing-roll patterns considered in the present work but the ratio of the phase distortion to the line width gets smaller as the width becomes smaller. Thus, the web handling speed and the shape of printing-roll pattern will be important elements for the better printing quality under 100 micron line width range.

A remote monitoring system of the semiconductor equipment is used to monitor or control operations of the equipment. Most of the conventional monitoring systems are based on the client-server model with the general purpose PC. Basically, it implies the difficulties in the system reliability and cost down due to its size and complexity. To overcome these difficulties, we suggest an embedded web server which is based on the low-cost microprocessor. It is designed for the monitoring or controlling a dedicated equipment only. To evaluate the feasibility of the suggested embedded web server, we have implemented a test-board with ATMega103 and programmed the basic modules using the AVR-GCC. Finally, we have tested its operations on the MS Explorer 6.0 environment.

In this paper, we propose a real-time ECG monitoring system for personal health records. This study aims to provide services that help patients to monitor their own physical condition and manage their own health records consistently, whereas existing medical services are Medical Institute-Centric model. The system is composed of web server, smart phone, and ECG meter, and web page. Without time and space restraints, It provides us with managing personal health records by performing patient's ECG measurement and real-time monitoring. And also Real-time bidirectional communication between smart phone and web page can be performed rapidly by applying the ECG monitoring with WebSocket Technology that follows HTML5 standard. Through this system, It can handle patient in need immediately.

In this paper, we propose a web inspection system (WIS) for real-time detection of paper defects which can cause critical fractures during papermaking process. Our system incorporates high speed line-scan camera, lighting system, and detection algorithm to provide robust and precise detection of paper defects in real-time. Since edge defects are very crucial to the paper fractures, our system focuses on the edge region of the paper instead of inspecting the whole paper area. In our algorithm, image projection and sub-pixel operation are utilized to detect the edge defects precisely and connected component labeling and shape analysis techniques are adopted to extract various kinds of the region defects. Experimental results revealed that our web inspection system is very efficient for detecting paper defects during papermaking processes.

Low-end IoT devices do not have enough computation and memory resources for DNN learning and inference. Integer quantization of real-type neural network models can reduce model size, hardware computational burden, and power consumption. This paper describes the design and implementation of a web-based quantization platform for CNN deep learning accelerator chips. In the web service platform, we implemented visualization of the model through a convenient UI, analysis of each step of inference, and detailed editing of the model. Additionally, a data augmentation function and a management function of files that store models and inference intermediate results are provided. The implemented functions were verified using three YOLO models.
