There are many statistical information sites as the use of internet is increased quickly in recent years. In this paper, we explore and analyze internet sites for statistical information such as statistical survey system, education, database, and terminology. And then we classify these sites to apply statistical information to some particular spheres easily. In so doing, this study result aims at enhancing our understanding of internet sites for statistical information.

According to the increase of internet application, the marketing process as well as the research and survey, the education process, and administration of government are very depended on web bases. All kinds of goods and sales which are traded on the internet shopping malls are extremely increased. So, the necessity of automatically intelligent information system is shown, this system manages web site connected users for effective marketing. For the recommendation system which can offer a fit information from numerous web contents to user, we propose an automatic recommendation system which furnish necessary information to connected web user using statistical learning theory and bayesian fuzzy clustering. This system is called collaborative CRM in this paper. The performance of proposed system is compared with the other methods using real data of the existent shopping mall site. This paper shows that the predictive accuracy of the proposed system is improved by comparison with others.

Recently, growth of internet causes rapid changes in many areas of statistics such as statistical computation and education. Especially, bootstrap is the most interesting statistical methods applying computer resampling simulation. In this study, we try to present how to use a method of bootstrap on the internet. We also develop to user a statistical system which is programed with java applet for user to handle easily.

본 논문에서는 교육 분야에 프로파일링을 활용하여 교사가 전문적인 통계 지식을 가지고 있지 않아도 운영이 가능한 성적 맞춤형 통계 분석 시스템을 개발하고자 한다. 이를 위해 프로파일링에 대한 기술을 교육 분야에 융합하여 학생 맞춤형 다차원 분석 시스템을 구축하기 위한 필요 요소들(프로파일링, 빈도/교차/기간별/이항/다항 분석)에 대해 살펴보았다. 실제 교육 프로파일링을 활용한 학생 맞춤형 다차원 분석 시스템을 구축하기 위한 전체 구성도와 구축 상황에 대해 언급하고, 각 통계적 방법을 적용한 알고리즘에 대한 구현 결과를 보였으며, 기존에 존재하는 시스템들과의 차별성과 우월성에 대해 설명하였다. 제안된 기술을 기반으로 시스템이 구축되면 수각자의 요구와 능력의 차이를 고려하여 정확한 목표 및 기준을 명확하게 함으로써, 공교육 만족도 제고를 통해 선행학습 및 사교육비 절감의 효과와 학생 개인의 능력과 적성에 맞는 자기 주도적 학습 실현이 가능하다.

전통적인 강의실의 기초통계학 수업에서 많은 학생들이 수업에 집중하지 못하고 있다. 수업 시간에 졸거나, 잡담하거나, 휴대폰을 만지작거리면서 다른 생각에 잠겨 있다. 인터넷이 가능한 컴퓨터실에서의 강의와 실습은 인터넷이 제공하는 콘텐츠와 부단히 경쟁을 해야 한다. 이러한 문제를 조금이나마 해결해 보려고 시도한 방안이 교수와 학생을 하나의 유무선 네트워크로 묶는 교육용 디지털 신경시스템 하에서 기초통계학을 가르치고 학생들이 공부하게 하자는 것이다.

Since the 4th Industrial Revolution is implemented based on superintelligence, new insights must be provided through convergence studies with other fields to find optimal solutions to create new ideas. In this paper, we intende to present improvement measures for probability and statistical education, which is an athlete's subject on data analysis and processing in the ICT(Information & Communication Technologies) field in the era of superintelligence of the 4th industrial revolution. This paper aims to strengthen competitiveness through early development and commercialization of new technologies by presenting probabilities and statistical curriculums that require linkage in the ICT field. Second, it is necessary to present an educational system diagram linking probabilities and statistics in the ICT field to prepare a mid- to long-term response strategy for ICT education in response to innovative changes. Third, through a survey, we intend to present an effective educational operation plan linking probability and statistics to ICT major subjects by analyzing the perception of probability, statistical importance, and utilization of majors in this field.

Purpose: This study explored a plan for improving the overall preventive activity of Korean Citizen-Corps-Active-in-Disaster (CAIND). Methods: The study used the documentary survey and the technical approach methods. This way, detailed information regarding civil anti-disaster organizations was found in scholarly monographs, specialty publications, and master's/doctoral dissertations. It further utilized the statistical yearbooks between 2015 and 2018 from the Korean Ministry of Public Administration, Security, and Fire Service, and the National Statistical Office, to discover practical problems through a statistical analysis. Volunteer activities being inherent, related issues were reviewed at the same time to for purposes of clarifying the characteristics of disaster prevention activity by CAIND. Results: The study provided four major suggestions for improvement. First, the quota management system of Korean CAIND considering the characteristics of rural areas should be supplemented. Second, the education and training systems of Korean CAIND should be established to satisfy regional conditions. Third, management members' readership competency in operating organizations, including that of the Korean CAIND captain in charge, should be strengthened. Fourth, the reward system for Korean CAIND activities should be improved. Conclusion: In the future, the results of this study are expected to be utilized as a basic data to develop Korean CAIND.

This paper presents a method for constructing and using transliteration rules which are based on Phonics, an instructional method for speaking and writing English letters. Conventional approaches to automatic transliteration often focused on statistical methods. However, the construction or the collection of correct transliteration examples is always the bottleneck of the statistical transliteration model. Also, in practical domains where the collection of such data is very difficult, such as education and tourism, it is reasonable to build a system without much qualified data. Furthermore, compared with Korean orthography of borrowed foreign words, the proposed approach is much easier to construct, and can generate more refined rules. The experimentation result shows that the proposed approach can improve the performance of a statistical-based transliteration system.

본 연구의 목적은 연령진급률 혹은 학년진급률을 추정하기 위한 방법으로 비례법을 사용한 이동평균법에 의한 알고리즘을 제시하는데 있다. 학년진급률에 따른 학생 수 추계방법으로, 이동평균법과 비례이동평균법에 의한 추정방법을 제시하고, 2027년까지의 서울시의 고3학생 수를 추정하여, 한국교육개발원의 2005년, 2006년, 2007년의 로지스틱함수 추정에 의한 고3학생 수 예측결과와 비교 분석하였다. 본 연구의 결과 출생아수의 분포와 비교하여 볼 때, 본 연구에서 제시된 비례이동평균법과 이동평균법의 예측결과가 한국교육개발원의 2005년, 2006년, 2007년의 고3학생 수의 예측결과보다 더 신뢰성이 있는 것으로 나타난다.
