In this paper, we introduce a web-based system that leverages the capabilities of the ρ(rho)-algorithm, which is a Structure Information Control Net (SICN)-oriented process mining algorithm, with open-source platforms, including Django, Graphviz, and Cytoscape, to facilitate the rediscovery and visualization of business process models. Our approach involves discovering SICN-oriented process models from process instances from the IEEE XESformatted process enactment event logs dataset. This discovering process is facilitated by the ρ-algorithm, and visualization output is transformed into either a JSON or DOT formatted file, catering to the compatibility requirements of Cytoscape or Graphviz, respectively. The proposed system utilizes the robust Django platform, which enables the creation of a userfriendly web interface. This interface offers a clear, concise, modern, and interactive visualization of the rediscovered business processes, fostering an intuitive exploration experience. The experiment conducted on our proposed web-based process discovery system demonstrates its ability and efficiency showing that the system is a valuable tool for discovering business process models from process event logs. Its development not only contributes to the advancement of process mining but also serves as an educational resource. Readers, students, and practitioners interested in process mining can leverage this system as a completely free process miner to gain hands-on experience in rediscovering and visualizing process models from event logs.

Coupled schemes between service-oriented architecture (SOA) and Web 2.0 have recently been researched. Web-based content providers and telecommunications company (Telecom) based Internet protocol television (IPTV) providers have struggled against each other to accommodate more three-screen service subscribers. Since the advent of Web 2.0, more abundant reproduced content can be circulated. However, because according to increasing device's resolution and content formats IPTV providers transcode content in advance, network bandwidth, storage and operation costs for content management systems (CMSs) are wasted. In this paper, we present a user centric CMS for open IPTV, which integrates SOA and Web 2.0. Considering content popularity based on a Zipf-like distribution to solve these problems, we analyze the performance between the user centric CMS and the conventional Web syndication system for normalized costs. Based on the user centric CMS, we implement a social Web TV with device-aware function, which can aggregate, transcode, and deploy content over social networking service independently.

본 연구는 국내 지하수 자료의 효율적 이용 관리를 위한 수량수질 정보의 통합관리 시스템인 "국가지하수정보지도" 구축을 위한 업무분석과 세부 설계를 실시하고 천안 및 대구지역에 시범 적용함으로써 그 효용성을 검토하고자 하였다. 본 시스템에는 지하수와 관련된 관측, 조사, 지구화학(이온분석 결과), 시설, 수질검사 및 도면 자료 등을 데이터베이스로 포함하고 있으며, 전국의 약 130만개 관정에 대한 상세정보를 기본 데이터로 활용한다. Web 환경의 GIS 시스템인 "국가지하수 정보지도"에서는 자료의 검색뿐 아니라 시계열분석, 공간분석, 지층단면작성 등의 분석 기능이 포함되어 있어 지방자치단체 공무원뿐 아니라 현장 기술자에게도 유용하게 활용될 수 있다. 앞으로 본 시스템을 지하수에 대한 표준 모델로 발전시키고 단계적으로 확장해 나감으로써 전국의 지하수 관리를 보다 체계적으로 수행 가능하게 될 것이다.

The importance of education is greatly emphasized in the IT era. However, teachers have to deal with teaching work as well as increasing non-educationalchores. One of those chores is student counseling. Nowadays, teachers have considerable difficulty in consulting students because they cannot visit their home and don't have enough information on students. Furthermore, students are not willing to participate in school counseling since they think school counseling is not of much help and is just time-consuming. Most of the current school counseling is focused on matters related to entrance into a school of higher grade such as choice of college. But, students need counseling on matters regarding their ordinary life. This paper suggests a web-based student-counseling system that may solve this problem. The paper identifies core requirements for the web-based student-counseling system, discusses its design and implementation and shows it is more effective than the current ordinary school counseling by experimenting on a group of students with this system.

본 논문에서는 대용량 전자메일 서버의 성능 데이터를 수집해 그 분석 결과를 웹 기반으로 관리자에게 제공하는 모니터링 시스템을 구현하였다. 이를 위해 전자메일 서버의 성능 데이터 수집 항목을 도출하고, 각 항목별 측정 임계치를 설정하여 전자메일 서버의 성능을 객관적인 수치로 표현될 수 있도록 하였다. 전자메일 서버의 성능 데이터 수집은 SCOM 2007 서버 모니터링 도구를 이용하였으며, 성능 분석 파라미터 설정은 마이크로소프트사에서 제공하는 Exchange 서버 관리 팩과 SCOM 2007에서 제공하는 모니터링 규칙을 이용하였다. ASP.NET 프레임워크 기반의 C# 프로그래밍을 통해 웹 기반의 성능 모니터링 프로그램을 개발했으며, 성능 분석 결과는 관리자에게 웹 기반의 성능보고서, 장애 보고서 및 가용성 보고서 형태로 제공된다. 장애 요소를 사전에 효율적으로 감지할 수 있어 본 시스템 적용 전후 비교시 60% 이상 장애 건수를 줄일 수 있었으며, 장애 발생시에도 복구에 소요되는 시간을 획기적으로 단축할 수 있었다.

WebDAV(Web-based Distributed Authoring and Versioning, RFC 2518)는 인터넷을 통하여 원거리에 위치한 다수의 작업자들 간의 협업을 지원하기 위한 프로토콜이다. 웹데브(WebDAV)는 웹 통신 프로토콜인 HTTP/1.1의 확장으로 인터넷을 통하여 다양한 콘텐츠의 비동기적인 협업을 지원하기 위한 프로토콜을 제공한다. 웹 기반의 협업지원 시스템이나 문서관리 시스템과 같은 기존의 응용 시스템에서 웹데브 기능을 제공 하기 위해서는 이러한 시스템들이 웹데브의 메서드(method)와 헤더(header) 정보를 다루는 추가적인 구현이 필요하다. 본 논문에서는 웹데브 명세를 지원하는 아파치 기반의 DAVinci(WebDAV Is New Collaborative web-authoring Innovation) 웹데브 서버를 개발하였다. 공개 소프트웨어 기반인 아파치(Apache) 웹 서버에는 웹데브를 지원하기 위한 mod_dav 모듈을 제공하고 있다. DAVinci는 mod_dav 모듈의 서비스 제공자 형태로 추가되어 웹데브의 자원과 속성 관리를 담당한다. 본 시스템은 자원을 파일 시스템에 저장하고 속성 정보를 PostgreSQL 데이터베이스로 관리하며 추가적으로 자원과 속성들 간에 비일관성이 발생하지 않도록 보장하는 일관성 관리자(consistency manager)를 제공한다.

Objectives: This study aims to evaluate the clinical validity of the system by conducting a clinical study to assess the diagnostic agreement between the system and Korean medical doctors. Methods: This study was conducted from September 7, 2023, to December 7, 2023, across five Korean medicine institutions, involving 100 adult participants aged 20-64 who consented to participate. Participants first entered their symptoms into a web-based program, which utilized an AI-based algorithm to diagnose 36 types of pattern differentiation. Subsequently, Korean medical doctors conducted face-to-face diagnoses using the same 36 types. The diagnostic agreement between the system and the doctors' diagnoses was analyzed using descriptive statistical analysis, and the results were expressed as a percentage agreement. Results: Analysis of the diagnostic data from 100 participants revealed that the web-based diagnosis support system identified an average of 7.76±0.79 patterns per patient, while Korean medical doctors identified an average of 7.99±0.10 patterns per patient. The diagnostic agreement between the system and the doctors showed an average of 7.08±1.08 patterns per patient, with an overall diagnostic agreement rate of 88.57±13.31%. Conclusion: This study developed a web-based diagnosis support system for traditional Korean medicine and evaluated its clinical validity by assessing diagnostic agreement. Comparing the diagnoses of the system with those of Korean medical doctors for 100 patients, the system showed an approximately 89% agreement rate with the clinical diagnoses. The system holds potential for aiding Korean medical doctors in pattern differentiation diagnosis in clinical practice.

Purpose. This study developed a web-based wound care course for undergraduate nursing students and evaluated the course's content, system, and student-satisfaction. Methods. This study was done in three stages, the development of the web-based wound care course, the implementation and evaluation of the course. The course was developed based on the ARCS model. 80 under-graduate nursing students to Y University in Korea used the web-based wound care program during four weeks. After that, they completed questionnaires, evaluating the contents, system, and their satisfaction. Results. Eighteen learning objectives were used to create the web-based wound care course and the course was developed with 7 chapters and 20 subsections. The analysis of the questionnaires showed a mean score for content and system-related items of 3.04 each, out of a possible 4 points. Student satisfaction items had a mean score of 2.89. Conclusions. The web-based course allowed students access to the course anytime and anywhere, and according to their own learning abilities. However this advantage would only be possible when nurse educators develop qualitative web-based course to meet the demand of a complex health care system as well as the needs of the students and the effectively incorporate it into traditional lectures.
