현재 무선 이동 장비인 핸드폰이나 PDA 등을 이용한 무선 인터넷의 사용이 급증하고 있다. 이러한 장비들을 이용한 전자 상거래를 신속하게 지원하기 위해서는 WAP 응용의 생산성 향상이 요구되고 있다. 본 논문에서 소개하는 WAPSiteGen은 데이터베이스부터 구축해야 하는 WAP 응용과 기존 데이터베이스를 사용하는 WAP 응용의 신속한 작성을 위해 필요한 EJB 컴포넌트들과 무선 응용의 사용자 인터페이스로 사용되는 WML 데크들과 함께 이데크를 구성하는 카드를 통해 이뤄질 질의를 처리하는 JSP 웹 컴포넌트들을 자동 생성하여 WAP 응용의 생산성향상을 지원하는 도구이다. WAPSiteGen은 EJB와 JSP 등의 컴포넌트 기술을 도입함으로써 3-계층 구조를 갖는 WAP 응용의 확장성, 재사용성, 이식성 등을 지원한다. 또한, 비슷한 기능을 지원하는 타상용 도구들과 달리 WAPSiteGen이 생성하는 응용은 질의의 대상인 개체와 연관된 모든 개체들의 집합을 한 단위로 검색 할 수 있어 연관된 정보들을 신속하게 제공할 수 있다.

EPCglobal Class-1 Gen-2 protocol has been proposed for UHF-band RFID systems. In Gen-2 standard, Q-algorithm was proposed to select a frame size for the next query round without estimating the number of tags. Therefore, the Q-algorithm has advantage that the reader's algorithm is simpler than other algorithms. However, it is impossible to allocate the optimized frame size. Also, the original Q-algorithm did not define an optimized parameter C for adjusting the frame size. In this paper, we propose an adaptive Q-algorithm with the different parameter $C_c$ and $C_i$ in accordance with the status of reply slot. Simulation results show that the proposed adaptive Q-algorithm outperforms the original Gen-2 Q-algorithm.

"The FAA's Next Generation Air Transportation System" is a comprehensive overhaul of U.S National Airspace System to make air travel more convenient and dependable, while ensuring the flight is as safe, secure and hassle-free as possible. At its most basic level, NextGen represents an evolution from a ground-based system of air traffic control to a satellite-based system of air traffic management. This evolution is vital to meeting future demand, and to avoiding gridlock in the sky and at U.S airports. NextGen will open worldwide's skies to continued growth and increased safety while reducing aviation's environmental impact.

NCBI 의 GenBank 데이터베이스는 전세계에서 수집된 염기 서열 데이터들의 집합이며, 그 중 특허로 등록되어 있는 데이터들을 GenBank 특허 데이터라 부른다. 본 논문에서는 한국생명공학연구원의 유전체 사업단에서 개발해 오고 있는 웹기반 GenBank 특허 데이터 검색 시스템의 설계와 구현에 대해서 설명한다. 본 시스템은 일반 속성(attribute)을 저장하고 검색하기 위해 DBMS 를 사용하고, DNA 시퀸스 검색을 위해 BLAST를 사용한 약결합 아키텍쳐(loosely-coupled architecture)를 채택하고 있다. 즉, 일반 속성으로 저장될 수 있는 데이터들은 데이터베이스의 테이블들의 컬럼 값으로 저장하고 SQL 언어를 통해 검색할 수 있도록 하였으며, DNA 시퀸스 검색을 위해서는 BLAST 에서 제공하는 인덱스를 구축하고 BLAST 명령어를 사용하여 검색할 수 있도록 하였다. 또한, 검색 결과들이 기존의 외부 특허 시스템과 연동하도록 하기 위해, 결과 분석 모듈을 구현하여 검색 결과들이 다른 웹 사이트의 데이터를 가리키도록 하였다. 마지막으로, 이러한 DNA 검색 시스템을 구현할 때에 고려해 되야 되는 이슈들을 설명한다.

PCI Express is high-speed point-to-point serial protocol, the system is designed by analysing loss and jitter through Eye Diagram. It is necessarily analyzing high speed serial signals when the PCI Express Gen3 which has 8Gbps physical signal speed is designed especially. This paper deals with topology extraction, channel analysis, extraction of s-parameters and system signal integrity simulation within transceiver buffer models through PCI Express Gen3 server connecting switch system design. Optimal parameters of transmitter buffer equalizer are found through solution space simulation of de-emphasis and preshoot parameters to compensate channel loss.

E-commerce is in wide use with the rapid advance of internet technology. The main component of an e-commerce application is a Web-based database application. Currently, it takes a lot of time in developing Web applications since developers should write codes manually or semi-automatically for user interface forms and query processing of an application. Therefore, the productivity increase of Web-based database applications has been demanded. In this paper, we introduce a software tool, which we call the WebSiteGen2, that automatically generates the forms that we used as user interfaces and the EJB/JSP components that process the query made through the forms for an application that needs a new database or uses an existing database. The WebSiteGen2 thus increases the productivity, reusability, expandibility, and portability of an application by automatically generating a 3-tier application based on component technology. Moreover, one user interface form that are generated by the WebSiteGen2 provides information on an interested entity as well as information on all the directly or indirectly related entities with the interested one. In this paper, we explain the functionality and implementation of the WebSiteGen2 and then show the merits by comparing the WebSiteGen2 to the other commercial Web application generators.

This study was conducted to develop menugen program: Korean recommended menu planning and search based on internet to promote self sufficiency of food in Korea. This program manipulate menu and search 432 Korean recommended menus which have been developed in combination of population characteristics of 9 age level, 3 residential areas, 3 income groups, four seasons and male or female. Clients can select the high self sufficiency recommended menu by inputting their age, residental area, income, season and sex in using Menugen program. MenuGen can analyze nutrients and compare with Korean Recommended Allowance about clients' menu based on their age and sex. It can access the food, dish and menu databases. And also client can use MenuGen program for menu planning and analysis nutrients. Client's menu data can be store, delete, modify and print through MenuGen too. It will be able to read the nutrition analysis data of the foods, the dishes and the menu. Therefore it provides convenient user interface to not only users but also dietitians and nutritionists, who take charge of making a menu, and experts in the field of food and nutrition. MenuGen will help the nutrition policy accomplishment and the food self-supply rate improvement of the nation with use of menu drawing up program of internet base.

In this paper, we propose an improved anti-collision algorithm. We have designed an anti-collision unit using this algorithm for the 18000-6 Type C Class 1 Generation 2 standard (Gen2). The Gen2 standard uses a Q-algorithm for incremental method on the Dynamic Slot-Aloha algorithm. It has basically enhanced performance over the Slot-Aloha algorithm. Unfortunately, there are several non-clarified parts: initial value. If an incorrect value is selected, it causes degradation in performance. To increase throughput and system efficiency, and to decrease tag identification time, we propose an improved anti-collision algorithm. prorosed Q algorithm has an increment of 5% of system efficiency and a decrement of 9% of tag identification time.

The demand for mobile database applications has been rapidly increased with the growth of mobile users and the development of wireless Internet technology. But the productivity of mobile applications is low and it takes much time to manage the versions of applications because the user interface and query processing code of applications is manually written. In this paper, we describe the design and implementation of the MobileGen that is a script generator for mobile database applications. The generated scripts enhance mobile application productivity by providing the code for operating with a database and processing user queries. Each script provides a corresponding deck that is a set of related cards as user interface. The MobileGen supports easy version management of generated applications and the MobileGen itself because it is based on the templates that are frameworks for scripts. Moreover, the MobileGen provides not only the interested entity but also the entities that are related directly and indirectly with the interested entity unlike the most commercial mobile script generators.
