While the body of cases on startup has grown substantially, there has been a lack of a one-stop gateway of entrepreneurship. The study attempts to build a subject gateway for startup information services based on case studies, users' needs analysis, and literature reviews. The results show that users have difficulty in selecting useful information since the excess of information and the search for the desired information as it is scattered across a wide range of sources. The study designed a subject gateway by a navigation system that enables flexible browsing within the entire gateway through the ontology modeling. The study also presented an example of startup records to display how startup information can be explored. This study is expected to contribute to the understanding of the current status related to business startup services. The business startup digital gateways based on empirical data analysis will contribute to extending library service for startup.

High unemployment rates repeatedly cause recurring social problems such as fewer employment opportunities and employment insecurity. Following this trend, various programs related to employment have been provided through various government and institutions. However, they have established overlapping policies and programs and there is no one stop gateway to find effective and efficient way to find relevant information. For this purpose, this study aims to provide employment and job search subject gateway development. The study has carried out case studies, literature reviews, and user survey. Based on this study, it suggested a linked metadata model to organize and link scattered information together, and a digital gateway operating diverse information services. It is expected to provide a basis to develop comprehensive information service model for employment.

The overload of internet information makes user many restrictions. Users are confronted with the problems of information quantities, search, quality and reliability without information needs, technology level, education background of user, when they use internet as a tool of information search and retrieval. Web academic information subject gateway which provides user web information resource of high quality is a solution for these problems. This article explores the characteristics about the establishment and administration of foreign web academic information subject gateway, and identifies the considerations for establishing and managing it.

In existing wireless ad-hoc networks, how to distribute network resources fairly between many users to optimize data transmission is an important research subject. However, in wireless mesh networks (WMNs), it is one of the research areas to avoid gateway bottleneck more than the fair network resource sharing. It is because WMN traffic are concentrated on the gateway connected to backhaul. To solve this problem, the paper proposes Weighted Fairness Time-sharing Access (WFTA). The proposed WFTA is a priority time scheduling scheme based on Weighted Fair Queuing (WFQ).

QoS is a subject of high interest for successful deployment of various services in a home gateway and the gateway is possible to support QoS by installing existing queuing disciplines, which control the outgoing traffic to guarantee only QoS of the traffic. But m the home gateway it is also important to guarantee QoS of the incoming traffic. This paper proposes an adaptive control of the traffic to guarantee QoS of incoming traffic into the home gateway. In the proposed method, the upper limit of the available bandwidth of sending rate varies with receiving rate. And the proposed method makes the gap between the allocated rate and the actual service rate of the traffic narrow. Some experiments on a test bed show that the proposed method is valid.

With rapid telecommunication development, university libraries began to provide traditional services as well as web-based services. For the web-based services, university libraries should collect, arrange, and preserve all types of information resources systematically to raise users access and convenience. Therefore, university libraries should be changed into a gateway, which emphasizes electronic collection and role of the internet. That is, university libraries should be a real space as well as a virtual space having collection ability and access paradigm. This research is intended to provide improvement plans through analyzing the collected data.

With the rapid change of information environment, this study suggests role models and strategies for the university library in Korea based on the subject specialization. By analyzing the current situation and problems of university library, this research presents various directions for the subject specialization. Major research issues are (1) university library's subject specialization directions, models, and factors, (2) subject specialized librarian' s role and education system, (3) basic framework for customized information service and user education, (4) enhancement of subject specialization through subject gateway, (5) academic information sharing system.

Internet has great potential to support many researchers' work. But it is difficult to locate high quality information on the web efficiently and effectively. This paper describes the current state and characteristics of subject-based information gateways(SBIGs) on the Internet and discusses some of issues involving system maintenance and management for information gateway development.

The design of gate and runner(delivery system) is one of the most important subject in injection molding. Delivery system is a channel to flow the polymer melt from the injection molding machine to the mold cavities. Also, delivery system affect quality and productivity of the part. The synthesis of delivery system of injection molding has been done empirically, since it requires profound knowledge about the moldability and causal effects on the properties of the part, which are not available to designers through the current CAD systems. GATEWAY is a knowledge module which contains knowledge to permit non-experts as well as mold design experts to generate the acceptable geometries of gate and runner far injection molded parts. A knowledge-based CAD system is constructed by adding the knowledge module, GATEWAY, to an existing geometric modeler. A knowledge-based CAD system is a new tool which enables the concurrent design and CIM with integrated and balanced design decisions at the initial design of injection molding.
