Much efforts to use educational games for students' learning is being made actively at home. In this study the action levels of the educational game and the learners' personality types are main variables to be explored. It is expected that the results of this study would suggest how to utilize educational games in teaching and learning. The above is the result of the research about the level of action of educational games, the type of the personality, and the intrinsic motivation. It is considered that the result can be enough information for learners, parents of students and teachers who try to use and develop educational games. For example, it can be an idea to construct menus considering characteristics of learners in various steps of designing and developing educational games. And it can help to improve learners' intrinsic motivation especially if games are developed, distinguishing games for extrovert learners from those for introvert learners.

Bus, a major transportation mode, doesn't have a systematical evaluation system for dangerous driving behavior yet. This paper analyzes the characteristics and pattern of bus driving behavior using Digital Tacho Graph(DTG) data on express bus. 8 types of dangerous driving behavior were considered according to timeslot, the day of week and weather condition. As results, rapid acceleration, rapid left right turn and rapid deceleratio accounted for more than 97% and relatively high percentages were shown in dawn, on Friday and on the clear day, respectively. From the statistical analysis, correlation between the dangerous driving types and difference according the timeslot were found, and 3 groups considering the level of the dangerous driving were suggested. This study contributes to setting an efficient and reliable eduction system for using driving simulators.

The purpose of this study was to investigate the subjective evaluation and the characteristics of each type of maternal self-awareness. It was to provide the basic data necessary for the development of clothing that can improve the satisfaction of the body shape of pregnant women. This study was conducted with Q methodology, and was performed for pregnant women over 6 months. Analysis was done with QUANL program. The recognition types of body shape of pregnant women was analyzed as three types: thin limbs and central hemispherical abdominal body shape, under abdomen protruding body shape, and thick upper arm and central abdomen protruding body shape. The thin limbs and central hemispherical abdominal body shape were considered to be normal, with the lowest BMI index before pregnancy. And the limbs were thin and the other parts were not overweight, but recognized that only the belly came out. The under abdomen protruding body shape was overweight with the highest BMI index before pregnancy. In addition to the circumference of the chest and hips, the body was gaining weight and was perceived to have a belly drooping down. The thick upper arm and central abdomen protruding body shape recognized that the middle part of the abdomen protruded like the first type, but it was different from the first type because the upper arm was thickened. In the future study, it would be a meaningful study to compare and analyze the difference with the recognition body of this study through analyzing the actual body shape of pregnant women.

The purpose of this study was to analyze the error patterns and sentence types in word problems with respect to 1$\frac{3}{4}$$\div$$\frac{1}{2}$ which were made by the pre-service elementary teachers, and to suggest the clues to the education in pre-service. Korean elementary teachers in pre-service misunderstood 'divide with $\frac{1}{2}$' to 'divide to 2' by the Korean linguistic structure. And they showed a new error type of 1$\frac{3}{4}$$\times$2 by the result of calculation. Although they are familiar to 'inclusive algorithm' they are not good at dealing with the fractional divisor. And they are very poor at the 'decision the unit proportion' and the 'inverse of multiplication'. So, it is necessary to teach the meaning of the fractional division as 'decision the unit proportion' and 'inverse of multiplication' and to give several examples with respect to the actual situation and context.

Search strategies is a means to make an efficient search. Among several studies of search strategy, Bates' $\ulcorner$Search Tactics$\lrcorner$ has been often cited and introduced, but their studies have been superficial. In this paper, the contents of Bates' $\ulcorner$Search Tactics$\lrcorner$ are examined in detail, and we try to represent the actual online search process based upon Bates' $\ulcorner$Search Tactics$\lrcorner$. The following three kinds of survey are made in order to clarify which and how tactics are used: (1) Interview with 7 searchers who belong to different types of organizations, and use different kinds of databases (2) Analysis of some online search records. (3) Analysis of written applications for a newspaper database during one year. In conclusion, Bates' tactics falls into categories and new several tactics which often used are added. The following five factors affect online search activities, search strategy, and search tactics. (1) the difficulty of search requests (2) the kinds of databases (3) the charging policy for each online search (4) the presence of the user during the search (5) the searcher' online experience In the limited condition, typical tactics are suggested, but in order to generalize the pattern of using tactics, further investigation is necessary.

The current study seeks to understand the multi-faceted desires of language learners through the theoretical lens of imagined communities (Norton, 2001). Particularly, the study focuses on the learners of Korean language-one of the less commonly taught languages in the U.S. that has received relatively less attention in previous literature on second language motivation. The study analyzed and compared the narratives told by eleven Korean language learners in a post-secondary language program, and identified four types of imagined communities: Communities of K-pop Culture, Communities of Professionals, Communities of Korean Family and Relatives, and Communities of ethnic Koreans. The study found that these imagined communities were not restricted to a specific region or an ethnic group but encompassed various populations connected through the use of Korean language. The study also found variability within what has been readily labelled as heritage motivation (or motivation related to heritage), as well as striking differences between heritage language learners and non-heritage language learners in terms of their scope of imagination.

Determining the percentage of negligence between the parties in the event of road traffic accidents is a significant problem. In order to provide users with more accurate criteria for determining the percentage of negligence, several companies are providing services. However, services currently available are limited to immediate use at the scene of an accident. Generally, the service that determines the percentage of negligence can be used after all accident handling procedures have been completed. This paper provides a real-time traffic accident type and fault rate information provision service utilizing a deep learning-based predictive model to overcome these limitations. Users can immediately identify accident types and fault information by taking pictures at the accident site and check actual precedents of the same accident type. Users will be able to use the service to more accurately and reliably determine the percentage of negligence and handle incidents.

The various types of play structures and environments in which the playful motivation of YouTube users is effectively implemented are the main backgrounds of YouTube development and activation. This study discussed the types of play in YouTube space by dividing them into 'Agon', 'Alea', 'Mimicry', 'Ilinx' categories. And, it was found that the types of play that can be experienced in YouTube spaces are not divided into clear boundaries, but the elements of 'competition', 'luck', 'mimicry' and 'vertigo', which are essential characteritiscs of each category, are fused into various combinations. As such, this study is sufficiently academic in the fact that it is a humanistic approach to YouTube. In addition, it is a practical research result that can be actually used in the process of planning and producing user-centered similar platforms in the future.

Field practicum is the core of Social Work education and plays a key role in the integration of theory and practice. To maximize the effectiveness of field education, it is important that both the faculty field liaison and field instructor are cooperated. However, the current field education is almost dependent on the supervision by field instructors. This study explores the perception on the areas of supervision by using the Q-methodology. As a result, the perception of faculty field liaison was categorized into three types and field instructors' was two. Their types of perception were partially overlapped rather than contrast. Findings of the study suggested the need for greater collaboration between academia and agencies.
