This study aims to find out changes of marital status and average marital life expectancy in Korea according to educational attainment. The study produces Korean marriage life table to accomplish the goal of study by introducing Wolfbein-Wool style working life table. Specific data utilized in this study are collected from the Population & Housing Census 2005 and Death Census 2005. Educational attainment is divided into four categories to accommodate to this study: elementary school course and lower, middle school course, high school course, college course and higher. Marriage rate, divorce rate, widowhood rate and death rate according to educational attainment are used as basicdata to analyze marital life expectancy. The results of this study are as follows: 1. As subjects age is younger, the average marital life expectancy of the highly educated tends to be higher. The disparity of average marital life expectancy according to educational attainment is apt to become narrow as subjects age is older. However, the gap between people who graduated from middle school and high school in older age group does not distinctive. 2. Males marital life expectancy is higher than females controlling for their educational attainment. 3. Males live with their wife for most of their lives but females live alone more than 10 years in every single educational categories. Based on the above, this study concludes that the average marital life expectancy is differentiated among age and sex according to educational attainment. Marital rate tends to be higher as educational level is higher. Divorce rate is lower in the highlyeducated group as their age is younger but this is apt to reverse as age is older. Furthermore, bereavement rate shows division according to educational attainmentsince one tends to marry other who has similar level of education with him or her. Therefore, educational attainment acts as an significant factor in Korean average life expectancy.

The purpose of this study was to examine the level of concern and the level of knowledge of endocrine disruptors, and the level of dietary behaviors to decrease exposure to endocrine disruptors, to determine the factors affecting the level of knowledge and behaviors, and to assess the causal relationship between them. The data were collected from 579 adults in Seoul, Incheon, Daejeon, Daegu, Busan and Gwangju provinces. Frequencies, t tests, analysis of variance, Cronbach's alpha, Pearson's correlation coefficient analysis, multiple regression analyses, and path analysis were carried out by SPSS for Win V.18.0. The results of this study were as follows: The level of concern about endocrine disruptors was higher than the medium level. The respondents were most concerned about a container of cup ramen among products related to foods. The levels of both knowledge and behaviors in order to decrease exposure to endocrine disruptors in dietary life were not high. The factors affecting the level of knowledge of endocrine disruptors were educational level, attendance in education for endocrine disruptors, and concern about endocrine disruptors. On the other hand, sex, age, concern about endocrine disruptors, and the level of knowledge of endocrine disruptors affected the level of behaviors to decrease exposure toward endocrine disruptors. The results of the path analysis showed that educational level and education of endocrine disruptors had an indirect influence on the level of behaviors in order to decrease exposure to endocrine disruptors in dietary life. The concern about endocrine disruptors had both a direct and an indirect effect on the level of behaviors to decrease exposure to endocrine disruptors in dietary life. In addition, sex, age and the level of knowledge of endocrine disruptors directly affected the level of behaviors to decrease exposure to endocrine disruptors in dietary life.

Information and communication brings us some degree of convenient but also serious side effects. Especially, information and communication ethics is an important issue for elementary school children who are early stage in moral value. This paper proposes a triple-connected teaching and learning model. which can be applied to the elementary school children. in order to improve the educational level. The model is formed by selecting three discretionary teaching models, and applying independently them into the different classes with linking the contents for each class. A teacher can choose the teaching models based on what he wants to teach. Caring model, Home-Connected model and Simulation model were linked in our experiment. Experiments were conducted in the same condition but different learning models, Then, an educational effect was compared and analyzed in the educational level improvement point of view, between the Triple-connected teaching and learning model and the single teaching and learning model.

Facility management is to maintain and develop the primary structural, functional, aesthetic performance of facility in order to guaranty the users' daily convenience and safety. However it is hard to maintain and serve their intended function and safe environment from the beginning as times go by. As present educational government of city and local area has been performing formally facility check and management as well as maintenance of school facility, it is hard to respond a dangerous situation at the suitable time and safety prevention plans are delayed. In addition, educational environment improving budget have been unreasonably decided not according to the allocating criteria. Therefore, this research developed a same, simple, and quantitative evaluation method of deterioration level of elementary, middle, and high School in Korea and verified usability of the method through the case study.

Most of the APP market today, it is biased in the field of games and entertainment. In contrast, market-share of the educational APP is very low. This phenomenon is due to two major problems. The first is a decrease in the reuse because of the test of simple pattern. The second is difficult to consider user-level range that was learned previously. In this case it is necessary for students to do additional effort. This paper, propose an educational intelligent educational APP to solve the problems described above and shows implementation results. This system analyzes the stored results that have been saved to determine the area of vulnerability. Time-based Re-validation module helps long-term memory of student. The proposed system in this way directly supports self-directed learning. Therefore, the students can be able to relearn weak area autonomously. It results in improved academic achievement.

Purpose: The purpose of this study was to determine the differences in the level of disease related knowledge, compliance of health behavior, and educational needs in relation to time (at discharge and 6 months after discharge) among patients underwent percutaneous coronary intervention (PCI). Methods: Data were collected from January 1, 2006 to September 30, 2006 and a total of 60 patients participated in the study. The survey was conducted in patients underwent PCI at the time of discharge right after discharge education was provided and at a follow up visit which was 6 months after discharge. Results: The level of disease related knowledge (p<.001), the compliance of health behavior (p<.001), educational need (p=.496), the sub-item of sexual life (p<.001), follow up (p<.001), diet (p=.021), stress (p<.001) in compliance of health behavior, and the sub-item of specific character of disease in educational needs (p=.015) were significantly different between discharge and 6 months after discharge. Conclusion: The results of this study suggested that further education should be provided to the patients underwent PCI regarding medication, smoking cessation, daily life and exercise at a time of 6 months after discharge in order to increase patient compliance of health behavior.

Aging educational facility shall be managed and maintained through integrated service perspectives, in consideration of functions of each facility to provide safe and comfortable environment, rather than temporarily fixing/repairing problems. For doing this, it is a must to firstly understand the limitation of highly biased performance-based maintenance practice, which is a most common type applied at present, and therefore to establish maintenance system that reflects the functions and characteristics of maintenance service that a facility was designed with. Therefore, the objective of this study is to find items that have an influence on service level recognition in order to fairly evaluate service functions of educational facilities, and subsequently to use these factors as ingredients of establishing a consistent and efficient maintenance system. Therefore this study proposed explanatory variables to measure influential factors for each major maintenance category. Then appropriate statistical verification was carried out on questionnaires that collected from a number of industry experts to test its fe asibility.

Technology-based convergence education is being emphasized for students in the era of the fourth industrial revolution. In math education, students need to increase their capabilities in the future by having them experience mathematical problems using robots and sensors, a key technology in the era of the fourth industrial revolution. To this end, it is necessary to present educational uses for educational robots in relation to math and curriculum from a 'mathematics education perspective' and analyze its educational use in relation to the mathematics and curriculum, considering the role of mathematics at the base of the process of exploring real-world phenomena and solving problems. Based on the analysis of Van Hiele levels of development in geometry and the LOGO activity level of Olson et al.(1987), this study analyzed and presented the level of LEGO Mindstorm activity, a representative educational Robot capable of collecting and analyzing data and programming in the form of block language, in the first to fourth level.

The Purpose of this study is to draw a few lessons for the effective teaching and learning throughout a comparative analysis on the results of the educational achievement on Mathematics of the primary and secondary school students. The primary sources for this research are based on the results of the six-times national level tests performed annually by all level students from 2003 to 2008. In order to achieve this goal, I, firstly, extract the lowest content area in terms of the annual average of the right answer ratio after examining the ratio of right answers to each math problem by classifying all multiple-choice questions of the educational achievement tests from 2003 to 2008 into the relevant content areas. Next, the characteristics of the content area which distinguish the lowest right answer ratio are qualitatively analyzed. Lastly, information on the content area which the school students of all classes feel very difficult to solve is provided via reckoning the average right answer ratio per each content area against all math questions at the last six-times of the national level tests.

The Internet is a highly distributed and complex system consisting of billion devices and has become the field of various kinds of conflicts during the last two decades. As a matter of fact, various actors utilise the Internet for illicit purposes, such as for performing distributed denial of service attacks (DDoS) and for spreading various types of aggressive malware. Despite the fact that numerous services provide information regarding the threat level of the Internet, they are mostly based on information acquired by their sensors or on offline statistical sampling of various security applications (antivirus software, intrusion detection systems, etc.). This paper introduces proactive threat observatory system (PROTOS), an open-source early warning system that does not require a commercial license and is capable of estimating the threat level across the Internet. The proposed system utilises both a global and a local approach, and is thus able to determine whether a specific host is under an imminent threat, as well as to provide an estimation of the malicious activity across the Internet. Apart from these obvious advantages, PROTOS supports a large-scale installation and can be extended even further to improve the effectiveness by incorporating prediction and forecasting techniques.
