Load balancing plays a crucial role in ensuring the stable operation of information management systems during periods of high user access requests; therefore, load balancing approaches should be reasonably selected. Moreover, appropriate load balancing techniques could also result in an appropriate allocation of system resources, improved system service, and economic benefits. Nginx is one of the most widely used loadbalancing software packages, and its deployment is representative of load-balancing application research. This study introduces Nginx into an educational administration system, builds a server cluster, and compares and sets the optimal cluster working strategy based on the characteristics of the system, Furthermore, it increases the stability of the system when user access is highly concurrent and uses the Nginx reverse proxy service function to improve the cluster's ability to resist illegal attacks. Finally, through concurrent access verification, the system cluster construction becomes stable and reliable, which significantly improves the performance of the information system service. This research could inform the selection and application of load-balancing software in information system services.

Purpose The purpose of this study is to identify problems of current educational facility data management and recommend a standardized terminology classification system as a solution. In addition, the research aims to present a preemptive and integrated disaster and safety management framework for educational facilities by seeking efficient business processes through secured data quality, systematic data management, and external data linkage and analysis. Design/methodology/approach A terminology classification system has been established through various processes including filtering and analysis of related data including laws, manuals, educational facilities accidents, and historical records. Furthermore, the terminology classification system has been further reviewed through several consultations with experts and practitioners. In addition, the accumulated data was refined according to the established standard terminology and an Excel database was developed. Based on the data, accident patterns occurred in educational facilities over the past 10 years were analyzed. Findings In the study, a template was developed to collect consistent data for the standardized disaster and safety management terminology classification system in educational facilities. In addition, the standardized data utilization methods are presented from the viewpoint of 'education facility disaster safety data management', 'data analysis and insight', 'business management through data', and 'leaping into big data management'.

Nowadays, social environment is rapidly changed toward globalization and information age, and which demands the new paradigm for active utilization of information system in the field of education and many others. The effort to adapt tele-communication technique to educational facilities and the planning to make virtual university come true are needed immediately. Intelligent Building system should be applied to educational facilities to cope with the changing and progressing building system. As a result of the surveying eleven domestic universities, it was found that library management system, administration automation system and office automation system were already introduced, but campus infrastructure such as network system and tele-communication system between buildings in campus have been constructed now. As the conclusion of this study, impeding factors and improvement direction for active utilization of intelligent building systems in university facilities were presented.

이 글은 교사나 연구사들이 저작권 침해 걱정 없이 교육용 콘텐츠를 다운로드받아 자유롭게 이용하거나 자신이 직접 만든 교육용 콘텐츠를 업로드 하여 타인과 공유할 수 있도록 하기 위한 '교육정보자유이용체제'의 구축 방안에 관한 연구이다. 본 논문에서는 우선적으로 '교육정보자유이용체제'와 유사한 성격을 가진 국내외 공개교육자원(OER, Open Educational Resource) 서비스들의 구축 형태를 분석한다. 그리고 이러한 분석 결과를 바탕으로 '교육정보자유이용체제'를 단계적으로 확장하여 구축하기에 적합한 새로운 모델들을 제시한다. 본 논문에서 제시한 모델들은 '수요자 중심형 모델', '사용자 참여형 모델', '집중 관리형 모델', '콘텐츠 신디케이션형 모델'에 해당하는 네 가지 모델로써 단계적으로 확장하여 구축하는 것이 가능하기 때문에 이용자의 요구사항을 유연성 있게 수용할 수 있다. 특히 기존 '전국교육정보공유체제'가 가졌던 저작권 관련 문제점을 단계적으로 해결할 수 있는 장점을 가진다.

초 중등학교에서는 교육활동 과정에서 생성된 성적 자료, 관찰 상담 자료, 심리검사 자료 등의 다양한 정보를 여러 형태로 축적하여 관리하고 있다. 그럼에도 불구하고 학생들을 다차원적으로 진단하고 파악하는 데 필요한 분석정보를 제공하는 교육용 정보시스템은 존재하지 않는다. 이것은 마치 환자에 대한 각종 검사 결과가 있음에도 불구하고, 의사가 임상 경험에만 의존하여 환자를 진료하는 상황을 연상시킨다. 교육부가 '제5차 교육정보화 기본계획(2014~2018)'의 '교육 빅데이터 활용 활성화 대책'에서 지적하였듯이, 교육용 정보시스템이 존재하지 않는 이유는 아직 이 분야에 대한 기초 연구뿐만 아니라 종합적이고 체계적인 연구가 부족하기 때문이다. 따라서 이 연구의 목적은 다양한 분야에서 활용되고 있는 분석정보시스템의 개념을 교육 분야에 도입하여 맞춤형 학생지도를 가능하게 하는 교육용 정보시스템을 설계하고 프로토타입을 구현하는 것이다. 이를 위해 직무분석과 표적집단면접조사를 통해 교육용 정보시스템의 핵심 기능과 내용을 정의하였으며, 네이버 프로토나우를 사용하여 프로토타입을 구현하였다.

We propose a model-based method for information alignment using educational standards as a case study. Discrepancies and inconsistencies in educational standards across different states/cities hinder the retrieval and sharing of educational resources. Unlike existing educational standards alignment systems that only give binary judgments (either "aligned" or "not-aligned"), our proposed system classifies each pair of educational standard statements in one of seven levels of alignments: Strongly Fully-aligned, Weakly Fully-aligned, Partially-$aligned^{***}$, Partially-$aligned^{**}$, Partially-$aligned^*$, Poorly-aligned, and Not-aligned. Such a 7-level categorization extends the notion of binary alignment and provides a finer-grained system for comparing educational standards that can broaden categories of resource discovery and retrieval. This study continues our previous use of mathematics education as a domain, because of its generally unambiguous concepts. We adopt a materialization pattern (MP) model developed in our earlier work to represent each standard statement as a verb-phrase graph and a noun-phrase graph; we align a pair of statements using graph matching based on Bloom's Taxonomy, WordNet, and taxonomy of mathematics concepts. Our experiments on data sets of mathematics educational standards show that our proposed system can provide alignment results with a high degree of agreement with domain expert's judgments.

The purpose of this study is to analyze cognition of middle school students on an educational institute of life. For this purpose, the three times of in-depth interviews which were performed the subjects, 6 middle boy＇s school student. The data passed through process of three dimension, abstraction of idea, categorization, interpretation. In this process, were discovered four category of educational institute of life. It was pilgimage, activity, system, and compare with school. The major results of this study were follows: first, an educational institute of life is natural of life to student and they accept the life themselves not coercion gradully. second, study of educational institute is repetitional and many and only for school test. third, system of educational institute is concenturated for study, in this point, students distinguish school with educational institute. fourth, in compare with school, educational institute is more comfortable than school. Also, educational institute take care of student more than school.

국가수준 학업성취도 평가는 2007년까지 표집 평가를 시행해 왔지만 2008년에는 해당 학년 전체를 대상으로 전수 평가 체제로 전환하였다. 이에 따라 학업성취도 평가 시스템에 대한 새로운 연구의 필요성이 대두되었다. 본 논문에서 설계하고 구현한 학업성취도 평가 시스템은 기존 시스템과 달리 도수 분포표를 이용하여 석차계산 시간을 단축하고, 성적 통지표 출력을 위한 점수 입력을 자동화하였다. 또한 구현한 시스템에서는 도 전체 학업성취도 현황, 총점 및 교과별 점수 도수분포, 문항난이도와 변별도, 오답지 매력도, 교과별 성취도, 성별 지역별 성취도, 교육 청별 성취도, 학교별 성취도, 개인별 성취도, 성적 우수자 현황 등을 분석할 수 있다.
