  • The major objective of the statistical analysis about industrial accidents is to determine the safety factors so that it is possible to prevent or decrease the number of future accidents by educating those who work in a given industrial field in safety management. So far, however, there exists no quantitative method for evaluating danger related to industrial accidents. Therefore, as a method for developing quantitative evaluation technique, this study presents feature analysis of industrial accidents in manufacturing field using QUEST algorithm. In order to analyze features of industrial accidents, a retrospective analysis was performed on 10,536 subjects (10,313 injured people, 223 deaths). The sample for this work was chosen from data related to manufacturing businesses during a three-year period ($2002{\sim}2004$) in Korea. This study used AnswerTree of SPSS and the analysis results enabled us to determine the most important variables that can affect injured people such as the occurrence type, the company size, and the time of occurrence. Also, it was found that the classification system adopted in the present study using QUEST algorithm is quite reliable.

  • The purpose of this study is to present a Freedom Inquiry Method by Revised Science Curriculum in 2007. This study introduced IIM(Independent Inquiry Method), PBL(Problem Based Learning), Small Inquiry Method, Science Notebooks, Project Learning Method about Freedom Inquiry Method. The results of this study are as follows: First, IIM(Independent Inquiry Method) is studying method in the inquiry process center. The inquiry process is composed of total 9 phases, inquiry subject really it is, detailed aim deciding, information searching, it searches, quest result it arranges, aim evaluation, the report making, it announces, it evaluates, it is become accomplished. Second, It is a studying method which it starts with the problem which is Problem Based Learning, study atmosphere creation phase, problematic presentation phase and sleep static problem solving the phase which it attempts, it is become accomplished with autonomous studying phase, coordinated studying and discussion studying phase, discussion resultant announcement studying phase, arrangement and evaluation. Third, Small Inquiry Method, Call it accomplishes the call grade of the students among ourselves 4~8 people degree where only the quest learning capability is similar within class. Also interaction and coordinated function of the members between it leads and the subject which is given in the group it cooperates and it solves with it is a quest method which arrives to aim of commonness. This method divides on a large scale in three parts, it becomes accomplished in programming phase, quest accomplishment and resultant announcement. Fourth, Science Notebooks learns a scientific contents and a scientific quest function and the possibility of decreasing in order to be, from the fact that the help which it understands. This planing, data searching, it searches, becomes accomplished with resultant arrangement, announcement and evaluation. Fifth, The Project Learning Method the studying person oneself studying contents, it establishes a plan and it collects it accomplishes process of etc. it evaluates it leads and a subject and information and with real life it is a method which it studies naturally from the learning environment inside which is similar. This is preliminary phase, project start, project activity and project arrangement.

  • As vessels are faster and bigger, higher safety navigation techniques have been required. In marine traffic area, buoy is to be one of the most important equipment, so that it should be built stable and robust. Verification in design level is good to accomplish it. This paper tries to implement visual program to confirm the external stability, which shows the movement on water by external factors such as wind, tide and current. Considering further requirements for additional influences or functions, design architecture for program introduces the concept of software component. Using Quest3D as the graphic tool, visual programming with software component concept can be implemented.

  • 사용자의 적극적 참여를 유도하는 교육용 UCG(User Creative Game) 퀘스트(Quest) 제작 시스템은 게임 내 역할수행(Quest) 구성 권한을 사용자에게 부여하여 게임 내에서 사용자가 제작한 자유도 높은 임무를 제공한다. 이를 바탕으로 적극적인 사용자는 재미요소와 교육적 목표를 가진 퀘스트를 구성, 제작한다. 퀘스트 제작 시스템을 통하여 생산되는 퀘스트를 통하여 양질의 퀘스트 데이터는 축척 된다. 이로 인하여 게임의 수명은 연장되고 게임 내 교육적 기능성 부여는 게임 개발자가 아니라 교육 전문가인 적극적 사용자를 통하여 이루어진다.

  • 지금까지 의사결정나무에서 분리 변수의 선택에 관한 연구는 많았으나, 대부분 연속형 변수와 명목형 변수에 국한되어 왔다. 본 연구에서는 순서형 변수에 주목하여 CART, QUEST, CRUISE 등 기존 알고리즘과 본 연구에서 제안하는 비모수적 접근 방법인 K-S test, framer-von Misos test 방법의 변수 선택력을 비교하였다. 그 결과 본 연구에서 제안하는 framer-von Mises test 방법이 다른 알고리즘에 비하여, 변수 선택력과 안정성에 있어서 좋은 성과를 보였다.

  • In this study we focus on variable selection in decision tree growing structure. Some of the splitting rules and variable selection algorithms are discussed. We propose a competitive variable selection method based on Kruskal-Wallis test, which is a nonparametric version of ANOVA F-test. Through a Monte Carlo study we note that CART has serious bias in variable selection towards categorical variables having many values, and also QUEST using F-test is not so powerful to select informative variables under heavy tailed distributions.

  • The purpose of this paper is to analyze quantitative learning motivation on G learning. For the purpose the paper has analyzed the learning motivation factors through students' review on G learning which had been done at La Ballona Elementary School in Culver City, USA in 2010. On the basis of contents analysis method, it showed what factors of G learning influenced students and raised their academic motivation. Students used the positive, active words such as good, fun, learn, accomplish, easy, quest in terms of learning process, interest and achievement. They also showed future G learning intention describing terms such as love and miss. Team Quest has been especially developed for G learning class this time. Students had to help each other to solve the team quests which is different from traditional textbook. The system raised students' academic motivation.

  • The game industry of the Republic of Korea is being firmly located with great benefit and value. As internet developing quickly, the online game of the Republic of Korea boosted up to the level of the best in the world. Online Game has been developed with various types to make the user satisfy. Among those, MMORPG(Massively Multiplayer Online Role Playing Game) is the most popular game type. MMORPG games have getting more popularity in many foreign market but some have failed. Therefore this essay analyzes the MMORPG which has most popular through out the 4 kinds dividing in "Play and Human" by Roger Caillois. Moreover I try to analyze and experiment. Also through out the accomplishing Quest from the Goonzu which is developed and serviced in China, it experimented and it analyzed. With the help of information technology.
