실시간 시스템에서 프로그램의 실행시간을 예측하는 것은 중요한 일이다. 기존의 언어에서는 실행시간은 예측하기에 힘든 요소들이 있다. Timing-C는 이러한 요소를 제거하고 사용자로부터 시간 제약을 입력받을 수 있도록 하였다. Timing-C언어를 이용하여 실시간 프로그램밍을 하기 위해 작성한 프로그램이 시간제약을 준수하고 있는지 알기 위해 시간 분석 도구가 필요하다. 시간 분석 도구는 작성된 프로그램의 실행시간을 제한하여 사용자에게예측된 결과를 알려주는 도구이다. 개발자는 이러한 도구를 이용하여 작성하고 있는 프로그램의 수행시간을 더욱 정확하게 예측할 수 있다.

The purpose of this study was to examine the effectiveness of drama program for early children by using method of meta-analysis. For the purpose of the study, master's theses, doctoral dissertations, and journal articles published in Korea up to April, 2017 were systematically reviewed. As a result, a total of 39 studies were eligible for the inclusion criteria. The mean effect sizes and test for homogeneity of effect size(Q-statistic) were analyzed by using Comprehensive Meta-Analysis software 2.0. The main findings of the study were as follows. First, the average effect sizes for drama program were ES=1.922 of verbal expression, ES=1.898 of emotional intelligence, ES=1.558 of creativity, ES= 1.292 of sociability. Second, by analysing the moderate variables of the effect size for drama program, 'age' of verbal expression, creativity and sociability, 'sessions' of verbal expression were statistically significant. Based on the study results, the research and practice implications were discussed.

최근 상용 소음 예측프로그램은 현황분석, 방음대책 수립 및 다양한 변수 변화에 따른 소음 예측 등 다양한 목적으로 활용되고 있다. 대부분의 소음 예측프로그램 사용자들은 상용 프로그램이 제공하는 초기 설정을 그대로 사용하고 있지만, 각 상용 프로그램의 초기 설정을 정확히 확인하는 사용자는 많지 않다. 본 연구는 국내에서 사용되는 상용 소음 예측프로그램의 초기 설정을 확인해 보고, 사용자의 프로젝트에 적당한 초기 설정의 변경 방법에 대한 정보를 제공하고자 한다.

As one of the techniques for analyzing malicious code, techniques creating a sequence or a graph of function call relationships in an executable program and then analyzing the result are proposed. Such methods generally study function calling in the executable program code through static analysis and organize function call relationships into a sequence or a graph. However, in the case of an obfuscated executable program, it is difficult to analyze the function call relationship only with static analysis because the structure/content of the executable program file is different from the standard structure/content. In this paper, we propose a dynamic analysis method to analyze the function call relationship of an obfuscated execution program. We suggest constructing a function call relationship as a graph using the proposed technique.

The purpose of this study was to analyze Korea STEAM Programs in the perspective of Engineering Design. A pilot study of analyzing 41 STEAM programs was conducted by using Guzey et al. (2014)'s STEM program analysis framework. Based on the pilot study result, we suggested specific criteria to analyze Korea STEAM program and developed an analysis framework by considering characteristics of Korea STEAM program we found. The analysis framework suggested by this study has 5 more criteria compared to the Guzey et al. (2014)'s framework. By using the suggested framework, we analyzed another 76 STEAM programs developed by the grant of Korea foundation for the Admin of Science & Creativity (KOFAC) in 2016. The analysis results show that only 28.5% of total 76 Korea STEAM programs are focused on Engineering Design and the programs categorized as 'Complete Engineering Design Lesson' were only 5.4%. More than half of the programs (62.3%) are focused on only science contents with crafting and/or concept drawing activities.

A performance monitor is indispensable to trace and evaluate performance of a program under distributed processing environment. A performance monitor il classified as off-line and on-line according to its output method. An off-line performance monitor analyzes its performance after a program terminates, and an on-line performance monitor analyzes its one while a program runs. Therefore, the on-line function is essential to analyzing and debugging the program fast. JaNeC, distributed processing environment that is implemented in Java, contains an off-line performance monitor for this. However, this performance monitor may not analyze the program running on JaNeC efficiently. Consequently, this paper explains that an on-line performance monitor is designed and implemented for fast analysis and debugging of the program running on JaNeC. This on-line performance monitor is designed to minimize effects on a program to analyze, and provides various forms of graphic output, to analyze the program effectively. In addition, even after a program terminates, it provides interface with the off-line performance monitor, to analyze again.

This study analyzed the effects of university-based science education programs on the gifted's science career orientation. The subject of this study was 74 students who had university-based science gifted education programs on 2014. They took 'Science Career Orientation' tests and questionnaires before and after the program. We had a cluster analysis about pre scores on 'Science Career Orientation' as a variable. We analyzed the satisfaction level and effect of science career decision by groups after the program. As results, they were divided into four groups by cluster analysis. University-based science education program helped the increase of science career orientation in the categories indicating the low scores of the groups. They showed high satisfaction level and positive effects of science career decision, and the programs affecting their science career decision and satisfaction about that were different by groups. Satisfaction level and effects of science career decision are highly correlated.

The purpose of this study is to provide the basic data on the development and application of parent education programs and suggest the direction of future studies by analyzing the trends of research articles related to parent education programs. For this, the articles on 'parent education programs' written in Korea from 2004 to 2014 were collected and analyzed. The number of articles analyzed is 202 in total: 41 doctoral theses, 88 master's theses, and 73 academic theses. Firstly, the basic trend of research of parent education program was examined per object and subject. Secondly, the trend of research of the development and implementation of parent education programs was examined by dividing the programs on the basis of the ground for development, object of application, subject, type of program designing, the number and hours of the program, method of conducting the program, program educator, program effects. etc. The results of the analysis of the data made it possible to find out the process of development and implementation of parent education programs conducted in Korea. Such research results were summarized according to the research problems and suggestions for follow-up studies were made on its basis.

The purpose of this study is to examine the effect of the disability awareness program and to search for its development plan. For this, the disability awareness program was developed and lecturers were educated. And it had been exercised and examined its effect to 508 people including elementary, middle and high school students and adults nationwide from June to October in 2017. To examine the effect of the program, Disability Awareness Index developed by Korean Foundation for Persons with Disabilities was used. It was also examined on the change of the disability awareness(understanding disability and human rights of disabled) and of the knowledge about discrimination and differentiation. Pre-post tests based on the experimental design were performed and data were analyzed using descriptive statistics, paired t-test, independent t-test and ANOVA. The research results showed as follows; Disability awareness was improved significantly and knowledge about discrimination and differentiation were enhanced after attending the program. Also, it was found that the factors like gender, age, and program types made significant difference to the effects of the program. Based on the research results, this study suggested for the development disability awareness program and the directions for future studies.
