The objective of this study is to implement geological functions on the Internet such as the visualization, search and analysis of geological data. To improve their performance and reduce the cost during development, special concerns should be given to the dynamic integration and interoperability of them. XML Web Service technologies can be adopted and OpenGIS specifications should be considered for the integration of distributed GIS components and their interoperability. Because standard Internet protocols and XML Messages are used in the Web Service, it makes the integration among different hardware and software systems possible. OpenGIS specifications also enable users to get benefits from geographic information and services across any network, platform and application. A prototype of efficient Internet GIS applications has been suggested in this study.

In the 21st century, the concept of remote design and manufacture is strongly required in manufacturing processes to reduce cost and time-to-market. The objective of this paper is the development of an internet-based dimensional verification system for reverse engineering. An inspection client can register measurement data at the developed web server. Collaborators related to the development of a new product can confirm geometrical form from measurement data, check dimensional information and mark up the important parts, as well as make a statement of their views through the Internet. The developed system is realized through the ActiveX-Server architecture. Functions of the dimensional verification module are constructed as ActiveX by using the visual C＋＋ and OpenGL. The usefulness of the developed system is confirmed through a case study.

For effective conservation of the oceans and harbors, long-term and systematic development of the ocean and harbor monitoring system is essential. A monitoring system capable of real-time and accurate data acquisition is necessary for dealing with the level of contamination by situations, such as red tide and foods. This paper introduces an effective and economical real-time harbor environmental monitoring system that utilizes PCS wireless data communication technology. The monitoring system has various functions, such as multiple communication, TCP/IP protocol for wireless internet access, system time synchronization, and bi-directional communication between the measuring device and the server. The system has been implemented at Shinseondae harbor pier in Busan to validate the system's stability and effectiveness in data acquisition. The acquired real-time ocean and harbor environmental data is expected to have a large effect, when shared with the public through the Internet.

This paper is about implementation issues for use of the Internet technology in education. An examination of the current status of virtual university provides guidance for subsequent prototype development. A virtual university is the Internet based process by which students increase their specific knowledge and skills via electronic interaction with content and people. Virtual university enables colleges and universities to provide students and faculty with network access to courseware and educational materials on multimedia servers free from time and geography constraints. In this paper, we present a prototype instruction support system (ISS). The ISS consists of the following components in architecture: Internet, software, hardware, database systems, users, and workflow. The ISS also assists several functions as follows: lecture notes, register processes, attendance checks, built-in boards, grading systems, questions and answers, electronic libraries, chats, and search engines. Our work will provide a guideline for the development of a virtual classroom for distance education and learning.

In the past, the Internet connected people together; recently, however it has been extended to the Internet of Things (IoT), allowing all things in the physical world to be connected. We call a new society in which everything is connected through IoT a 'hyper-connected society'. IoT for a hyper-connected society is more than just connecting things to the Internet, it is an infrastructure providing intelligent services without human intervention by connecting things to the Internet using sensors and communication functions, collecting data from connected things, and analyzing and predicting information. Therefore, IoT is a convergence technology that includes not only sensors and communication networks but also big data and AI. This paper examines the short history of IoT, reviews its current trends, and finally, discusses its future direction.

For effective conservation of ocean and harbor, long-term and systematic development of the ocean and harbor monitoring system is essential. The monitoring system capable of real-time and accurate data acquisition is necessary for dealing with contamination such as red tide and the flood. This paper introduces the effective and economical real-time harbor environmental monitoring system that utilizes PCS wireless data communication technology. The monitoring system has various functions such as multiple communication, TCP/IP protocol for wireless internet access, system time synchronization, bi-directional communication between the measuring device and the server.

In this paper, a new distributed intelligent control module based on LonWorks fieldbus for air handling unit(AHU) of heating, ventilating and air-conditioning(HVAC) is proposed to replace with a conventional direct digital control(DDC) with 32 bit microprocessor. This article also addresses an Internet-based HVAC system architecture that combines Web technology and networking. The proposed control architecture has a excellent features such as highly compact and flexible function design, a low priced smart front-end and reliable performance with various functions. This also addresses issues in control network configuration, logical design of field devices by S/W tool, Internet networking and electronic element installation. Experimental results showing the system performance are also included in this paper.

인터넷 주소가 웹 사이트를 지칭하던 때와는 달리 웹 사이트 안에 담겨진 개별 서비스/콘텐츠/상품 등으로 세분화하여 지칭할 수 있게 되는 개방형 도메인 서비스가 국제 인터넷 주소 관리기구(ICANN)에 의해 도입되고 있다. 개방형 도메인은 서비스/콘텐츠/상품 단위의 주소를 표현하는 데에 더 적합하다. 본 논문에서는 사용자의 차별적 상황과 무관하게 주소 표현에 대해서 일관된 매핑 결과를 반환하는 정적인 인터넷 주소 서비스에 대한 대안으로, 사용자의 특정 요구에 맞추어진 매핑 결과를 반환하는 동적 인터넷 주소 모델을 설계하고, 기존 도메인 프로토콜의 변경 없이 주소 서비스 구현이 가능한 방법을 제안한다. 사용자의 메타 정보 및 환경 정보를 인터넷 주소 표현에 인코딩하여 첨부하고, 네임 서버에 동적 매핑을 위한 모듈을 추가하여 동적 인터넷 주소의 구현이 가능하다. 이를 통해 인터넷 주소의 기능 확장을 도모하고, 인터넷 주소 자체만으로도 사용자에게 맞추어진 정보검색 서비스가 가능할 수 있을 것으로 기대된다.

A brassier supports and protects breasts and makes a better shape of the upper half of the body through shaping breasts. A brassier, therefore, is recognized as the key underwear for female. Recently, the distribution structure and channels of the brassiere industry is diversified from conventional type of markets to department stores, convenience stores, and internet shopping mall. Studies on the sales of brassieres via internet, however, is not sufficient even though the market size has been dramatically increased thursdays. The study on the size structure (including the size and the materials fabric of brassieres circulating via internet) is especially rare. Therefore, this study tries to comply with increasing requests of consumers through comparing brassier brands on internet. In depth, this study compares cases of Korea and Japan in terms of availability of website on sales, quality indication like materials and functions, and size. The results indicated that there were three companies in Korea which run a website and make a sale through a website. All three Japanese companies operate a website and make sales on a website as well. In terms of size, Korean companies diversify their size of products in two ways. It varies from A cup to D cup based on cup size, and 65 to 100 according to its entire size. On the other hand, Japanese companies use AA, A to I to measure cup size, and 65 to 100 for entire size.
