Education of 'Law and Order' is necessary in our recent society. However it is so difficult subject for students in the elementary schools to be learned efficiently. In this research, we have studied how to utilize the game as an educational contents with good effects of the game. And we have designed a game in which children could experience various situations where they had to make decisions based on proper law and order. Parents were also encouraged to participate and play along the game with role balances as mentors to their children. The effectiveness was tested with experience of the developed prototype game and questions. Through the study we expect and hope to use games as effective learning tools for children in the future.

Liver cancer is the most fatal cancer that occurs worldwide. In order to diagnose liver cancer, the patient's physical condition was checked by using a CT technique using radiation. Segmentation was needed to diagnose the liver on the patient's abdominal CT scan, which the radiologists had to do manually, which caused tremendous time and human mistakes. In order to automate, researchers attempted segmentation using image segmentation algorithms in computer vision field, but it was still time-consuming because of the interactive based and the setting value. To reduce time and to get more accurate segmentation, researchers have begun to attempt to segment the liver in CT images using CNNs, which show significant performance in various computer vision fields. The pixel value, or numerical value, of the CT image is called the Hounsfield Unit (HU) value, which is a relative representation of the transmittance of radiation, and usually ranges from about -2000 to 2000. In general, deep learning researchers reduce or limit this range and use it for training to remove noise and focus on the target organ. Here, we observed that the range of HU values was limited in many studies but different in various liver segmentation studies, and assumed that performance could vary depending on the HU range. In this paper, we propose the possibility of considering HU value range as a hyper parameter. U-Net and ResUNet were used to compare and experiment with different HU range limit preprocessing of CHAOS dataset under limited conditions. As a result, it was confirmed that the results are different depending on the HU range. This proves that the range limiting the HU value itself can be a hyper parameter, which means that there are HU ranges that can provide optimal performance for various models.

A poor achievement of basic competency leads to obstacles of the same subject and other subjects from a series of accumulative losses and social life. The Grade 3 National Diagnostic Assessment of Basic Competency (NDAHC) dated from 2002, Teaching Plan Responsible to Basic Competency and compensational education materials for students of the below-basic level has marked a line in the chain of policy to realize educational welfare. The goal of NDABC is to collect information of the reason with regard to learning deficiency and individual student's information, and ultimately teach them on the basis of those informations. This study analyzed the characteristics of below-basic students in the basic mathematics with data from NDABC from 2003 to 2007. Students of the below-basic level were affected in achievement by numerical distinction, regrouping, arrangement and descriptive form of item, information-providing way, typical example, familiarity, frequency in use in daily life etc. This study provides a basic important information with regard to teaching below-basic students and suggestions with compensational education materials for them.

The purpose of this study is to compare and analyze middle school students' understanding of constant rate of change, in terms of observing, representing and interpreting dynamic functions in various ways using the SimCalc MathWorlds. For this purpose, parts of a class conducted for six students in the first grade of middle school were analyzed. The results suggested two implications for a class that used this program (SimCalc MathWorlds): First, we confirmed that the relationships between the two quantities that students notice in the same situation can be different. Second, the program helped students to develop a more comprehensive understanding of the meaning of the constant rate of change. The study also revealed the need to use technology in teaching and learning about functions, particularly to represent and interpret a given situation that involves the constant rate of change in various ways. Further, the results can contribute to developing contents and methods to teach functions using technology in consideration of students' different levels of understanding.

The National Health Promotion Law passed in 1995 was a milestone for initiating a national health promotion program in Korea, and government officers and health professionals are working on how to approach health promotion issues. The purpose of this study was to analyse methods and use of constructivist paradigm in health promotion and education. The health promotion area needs community empowerment, building community partnerships, and community capacity. To meet these health promotion requirements health promotion workforce should be trained through professional preparation programs that contains communication skills, group process skills, and management of programs in advanced countries such as the United States and Australia. Skills and responsibilities of those who are in charge of providing health promotion services have not yet been clearly defined in Korea because the area of health promotion is a multi-academic field, and needs a different approach, constructivist approach. Constructivist paradigm requires relativism, reasoning skills, collaborating, and motivation. These components are needed for community empowerment. Constructivism also has been applied to the field of education. Problem-based education, outcome-based education, performance-based education came from the constructivism. These educational methods are student-centered method. As the modernizing society becomes more complicated, traditional or conventional teacher-centered education cannot meet the needs of students. Students need to learn skills necessary to make healthy decisions with individual value system. So these interactive, self-learning methods can serve much more to the learner. Constructivist educational methods can be applied to educational programs in computers, too. To expand and differentiate the area of health education and health promotion from other health related fields, it is crucial to devote efforts in application and development of constructivist methods.

Korean semantic role labeling (SRL) is usually performed by a machine learning and requires a lot of corpus. However, the Korean PropBank used in Korean SRL system is less than PropBank. It leads to a low performance. Therefore, we expand the annotated corpus and verb frames for Korean SRL system to expand the Korean PropBank corpus. Most of the SRL system have a domain-dependent performance so, the performance may decrease if domain was changed. In this paper, we use the domain adaptation technique to reduce decreasing performance with the existing corpus and the small size of new domain corpus. We apply the domain adaptation technique to Structural SVM and Deep Neural Network. The experimental result show the effectiveness of the domain adaptation technique.
