Recently, because of decreasing in population, most of local universities are competing to attract new students in the entrance examination. These situations cause that most of the examinee apply for several universities to matriculate in a university. So these problem may raise a serious trouble such as additional new students invited. Therefore, in this study, we consider a few statistical models by using data mining technique to understand the pattern of new students who discard registration(seceders) in spite of success in the D university entrance examination. To construct these models, we use entrance examination data of three years. On the basis for analysis results of entrance examination data, we look into the features for secession of new students who success in an university entrance examination. We provide a basic information to make a effective entrance plan for seceders in future. Also, we make a search for the trend based on three years by analyzing entrance examination data of 2006, 2007 and 2008 years.

This paper introduces development of a Military Entrance Control System using the developed military insignia UHF RFID tags. Generally, in the military entrance control system, the security identification (ID) card with HF RFID tag can be used, to increase the security level, the developed insignia UHF RFID tags are used in the enforced military entrance control system. The general metal insignias, have been worn on a hat or on the shoulder pads of a military uniforms, are simulated and developed as UHF RFID insignia tags. The military entrance control system can manage the name, rank, address (information of military personnel), time and date of entrance and the history of entrance of the security area.

A vast amount of the national college entrance information and a broad range of contents make it more difficult for user to find, collect and compare the data. In this study, we find out how users work to collect, compare data through the usability test and take cognizance of difficulty and requirements on national college entrance information web-site. And then we give the planning for designing national college entrance information web-site through a personalized information architecture(PIA) system. Namely, this paper provides a guideline for designing a user-centric personalized information architecture(PIA) system through the usability test.

In this paper, we focus on churn analysis for the first successful candidates in the entrance examination on 2006 year using Clementine, data mining tool. The goal of this study is to apply decision tree including C5.0 and CART algorithms, neural network and logistic regression techniques to predict a successful candidate churn. And we analyze the churning and nochurning successful candidates and why the successful candidates churn and which successful candidates are most likely to churn in the future using data from entrance examination data of K university on 2006 year.

Objectives : The purpose of the study was to investigate the influencing factors of major and university choice in the changing environments that kick out the insincere universities keeping pace with the national policy. Methods : A self-reported questionnaire was completed by 177 subjects after receiving informed consents. The questionnaire consisted of general characteristics, influencing factors on university and department choice including multiple application. Chi-square test was used for analysis of the difference between early and regular admission. Results : Employment was the most important reason for choice of dental hygiene department that accounted for 96%. The access route for university information was college homepage for entrance information that accounted for 72.3% and 76.3% of applicants were advised by their parents for their choice for university. The information was mainly composed of school life(92.1%) and employment (81.9%). The applicants wanted to meet the students(58.8%) and to come in contact with the university homepage(57.1%). Early and regular applicants differed in reasons for college entrance(p=0.032), information delivery for major(p=0.013) and multiple application for entrance(p<0.01). Conclusions : University homepage and communication with the students will give much information to the applicants. So the university had better choose the homepage and communication for marketing strategy.

This study had a purpose to find the correlation between academic achievement and entrance examination score using FCA and framing a concept of university academic achievement and entrance examination score and then, building concept lattice. The subject for this analysis was admission materials of freshmen in computer engineering department at A university located in Chungcheong area in 2010. Also 56 students in total were subjects for the score analysis of their first semester from 2010 to 2014. The major findings of this study were as follows. We organized and extracted many-valued context, concept lattice, associated rules using FCA. And we analyzed the correlation between University academic achievement and entrance examination score using FCA. The conclusions were as follows. We could get meaningful analyzed results using FCA. University academic achievement had lower relativeness with entrance examination score and female students had higher university academic achievement than male students. The improvement points are summarized below. It is necessary to improve the ratio and application method of the university admission factors and to increase the regular admission for a university. And programs for completing College-preparatory programming for male students in low university academic achievement are necessary.

Objective: The purpose of this study is to find the tendencies and differences of mother's child-rearing anxiety before and after their children enter into elementary school, to analyze the factors influencing child-rearing anxiety at each time, and thereby to seek a support plan at the time of transition. Methods: The subjects of this study were 181 mothers who participated in two surveys which were conducted before and after their child entered into elementary school. Results: Firstly, mother's child-rearing anxiety before and after their children's entrance into elementary school was at a middle level, but increased significantly when they experienced their children's transition to elementary school. Secondly, mother's child-rearing anxiety, before their children's entrance into elementary school, was influenced by private education, the collection of educational information, cognitive ability, whether or not to develop a work status change plan, and birth order sequentially. Thirdly, child-rearing anxiety after their children's entrance into elementary school was significantly influenced by child-rearing anxiety before their children's entrance into elementary school and the mother's employment. Conclusion/Implications: This study is meaningful in the point that it suggested the necessity for the cooperation between multiple systems, such as systematic and stepwise parenting education, the importance of offering information to educational institutions and local governments, and for work- family support policy to prioritize children in order to support children's successful transition into elementary school.

By analyzing each part of expsure condition and the status of an entrance dose which is exposed to patients, this study reached the following conclusion. Since there is no standard in setting up an exposure condition, the technology practiced in each facility varies tremendously, and the entrance dose increased especially due to the improper selection of screen and grid and the shortage of a total amount of filtration in leaching the standard filtration amount. Entrance dose was, generally, turned out to be $2{\sim}3$ times as much as that of advanced countries, and there was big difference between facilities ; approximately 52 times inlateral of cervical vertebrae, 35 times in A-P of femur, 33 times in chest A-P, and 11 times in lumber A-P. Therefore, to minimize the entrance dose of a patient with thegreatest amount of image information, acquirement of technological know-how necessary for standardization of exposure condition for each part can be an important research task.
