This paper present a design and implementation of a Contents Management System (CMS) to be integrated into a game that uses a Digital Game-based Learning (DGBL) approach for helping tourists learn about tourism spots as a part of the Package Tour Application. In terms of design, this paper shows a system architecture that consists of a database to store the game's content such as tourism spot information, score and question configuration, score history, et cetera, a web application to manage the content and a Rest API to delivers the content to the mobile game. Meanwhile, in terms of implementation, MySQL database and PHP programming language are used. Moreover, a time response performance evaluation is conducted which resulted in between 0.77 s to 1.4 s from CMS to the database. Once successfully integrated with the game, the CMS will allow the game to be played on multiple tours simultaneously, without having to rebuild the game for every package tour group.

최근 들어 기업이나 관공서, 기관 등에서 상호간에 정보를 서로 교환하거나 사용자에게 게시할 때, 대부분 웹을 통해 브라우저에서 볼 수 있도록 HTML(HyperText Markup Language)형태로 제작하게 된다. 그러나 HTML로 제작된 웹 페이지는 구조적인 정보나 다양한 정보를 표시할 수 없다는 문제점이 있으며, 빠르게 변하는 정보인 경우 상세한 정보 표현 면에서 취약하다는 단점이 있다. XML(eXtensible Markup Language)은 이러한 문제점을 해결할 수 있는 마크업(markup) 언어로써 차세대 데이터 교환의 표준으로 채택하고 있다. 한편, XML이 HTML보다 더 나은 구조와 기능을 제공하고 있으나 XML 자체만으로는 XML이 가지는 여러 가지 장점들을 충분히 활용하기 어렵기 때문에 스크립트 언어의 사용이나 애플리케이션의 제작이 필수적이다. 본 논문에서는 효율적인 정보의 교환과 공유를 위해 XForm과 XML Query를 사용하여 정보를 데이터베이스에 저장하고 XML 형태로 추출, 교환할 수 있으며, 서버(server)와 클라이언트(client) 사이에서의 정보 교류뿐만 아니라 유사한 컨텐츠를 제공하는 여러 서버들간의 정보 공유를 지원하는 정보 처리 시스템을 제안한다.

This study is to develop a web-based real-time agricultural flood management system(RAFMS) for 378 agricultural reservoirs equipped with auto water level gauge stations. The RAFMS was designed to operate linking with Rural Agricultural Water Resource Information System(RAWRIS) which supports data viz. real-time rainfall and water level necessary for RAFMS. The system was constituted to monitor the floods simultaneously at each reservoir by calculating the real-time reservoir inflow from watersheds, water level, and release to downstream. In addition, the system has the prediction function for the flood by applying weather forecasting data from Korea Meteorological Administration(KMA).

This study compared and analyzed 15 CBMR (Content-based Music Retrieval) systems accessible on the web in terms of DB size and type, query type, access point, input and output type, and search functions, with reviewing features of music information and techniques used for transforming or transcribing of music sources, extracting and segmenting melodies, extracting and indexing features of music, and matching algorithms for CBMR systems. Application of text information retrieval techniques such as inverted indexing, N-gram indexing, Boolean search, truncation, keyword and phrase search, normalization, filtering, browsing, exact matching, similarity measure using edit distance, sorting, etc. to enhancing the CBMR; effort for increasing DB size and usability; and problems in extracting melodies, deleting stop notes in queries, and using solfege as pitch information were found as the results of analysis.

본 논문에서는 .NET 기반의 Remoting 시스템과 Socket 통신을 이용하여 이 기종 DB Server 간의 Data 동기화를 구현하였다. 이 시스템은 Client 의 웹 브라우저를 이용 Socket 통신으로 Data를 전송하여 데이터베이스에 저장하는 방식으로 구현하였고, Data 읽기는 Remoting 기술인 중계 어플리케이션 서버의 클래스를 원격으로 실행시켜 Data를 가져오는 방식으로 구현하였다. DB 동기화는 Data를 저장할 때 중계 어플리케이션 서버와 DB 서버의 Data 관리 어플리케이션 간 비동기 통신으로 DB 서버의 Data 처리 수준을 실시간으로 감시하여 중계 어플리케이션 서버에서 선택적으로 Data를 전송하고, 이후 Data 처리 수준이 정상화기 되면 다시 Data를 전송케 함으로써 이 기종 DB 서버간의 동기화를 구현하였다. 본 논문은 1 장에 서론, 2 장에 .NET Remoting 기술과 네트워크 프로그래밍, 3 장에 이 기종 DB 서버 간 동기화 시스템 설계 및 구현, 4 장에 결론을 기술하였다.

In this paper. the design and implementationof the on-line registration system for the school affairs is described. The environments for the system configurations include a PC server under Linux Iperating System. Apache Web-server, and MySQL as database engine. In addition, PHP, which becomes a popular Internet server-based script language lately, is used to implement a real-time database. In order to avoid overload problems during short-term registration period, which deconstraces the typical surge of traffics, the proposed system is designed to minimize the unnecessary interfacing tasks. On administrator side task, the sytem is designed to have environments by separating the dechcated server that restricts the scope of specific database thasks. In doing so, it become possibal to build an optical system by distributing, balancing the transaction load, maintainimg the security and efficient administrative tasks.

In this paper, we suggest the GUI Management Tool, named K-Manager, for management and service of science and technology information that stored in distributed retrieval databases. Generally, it must be adapted retrieval database system for web based S&T contents service. But, It is inconvenient contents manager or the system administrator controls information easily, because it does not support the S&T information management process like TOAD, which can use for the relation database, in information retrieval database system. Using K-Manager, content manager can process the S&T content and system manager can manage the databases easily. The proposed tool active controls information effectively which is stored in the distributed retrieval database which guarantee the safety management of the contents stored in database and operate retrieval with efficient performances. Our tool consists of two sub systems, one is content manager, the other is database manager for YESKISTI based on KRISTAL-IRMS.

Recently, though there are many REES(Remote Education Estimation Systems), they have some tied and complete testing method not considering for the student individual specification and characteristic. This paper proposes the education model of the distributed asynchronous communication method which making a test without me and place limits using web estimation system from problem bank database, and attach effective method could improve student achievement, quality of estimation later problem filtering using user profile in order to consider the student individual difference and characteristic that not considered pre-Remote Education Estimation Systems. This is a adaptive DAC method improving the pre-DAC method.

The Aircraft Development Department operated a Technical Document Management System that was effectively managed using a database management system for the management of the technical information created by a research and development phase of an aircraft and managed a technical information of a research and development varied by the project on a lot of the aircraft development program. While managing the user management and technical information project, it caused some problems on the workflow of the Work Memo and a search of some technical information, etc. As result, we developed the web-based Integrated Technical Information System(ITIS) which be able to totally manage the Technical Document Management System varied by program. According to the construction and operation of this system, we can access by program using user account and privilege and dramatically increased the productivity of a research and development because of performing the workflow of the Work Memo and some search of technical information by the integrated screen of the ITIS.
