The purpose of this study is to determine factors affecting text difficulty and to model objective formulas which measure readability scores. Some readability-related factors such as total number of letters, total number of syllables, total number of unique syllables, total number of sentences and total number of paragraphs were found through correlation analysis. Some regression equations with these factors as their variables were produced through regression analysis. A model estimating readability score from total number of unique syllables was a good formula, while a model with two factors, total number of unique syllables and new syllable occurrence ratio, was a better enhanced one. The readability score represents detailed level so we can recommend students read texts corresponding to their reading levels.

We investigated the influences of 'Circumstance Insensibility', 'Unsafe Driving', 'Incautious Driving', and 'Self-efficacy of Driving', consisting of driving confidence level, on traffic accidents. 1055 drivers conducted Driving Confidence Level Questionnaire, items about their dangerous driving experience and traffic accidents. Among them, after checking the missing items, we analyzed data of 998 drivers. As a result, we found the relation between driving confidence levels and traffic accidents. Specially, 'Circumstance Insensibility' and 'Unsafe Driving' influenced traffic accidents. However 'Circumstance Insensibility' had negative effects, the other side 'Unsafe Driving' had positive effects on traffic accidents. This result means each factor of driving confidence levels have different relation with traffic accidents. 'Incautious Driving' and 'Self-efficacy of Driving' didn't have any effects on traffic accidents in this research. In future, it should be investigated 'Incautious Driving' and 'Self-efficacy of Driving'.

Firms are confronting the age of an infinite competition. In order to respond to the rapidly changing business environment and make a success and survival in the international and domestic securities market, firms must take a consideration on the stockholders value-oriented philosophy which has greatly contributed not only to the maximization of corporate profits but also to the stability of financial markets. To pursue stockholders value-oriented philosophy, a firm should build strong relationship with investors by providing exact information of firm's state, financial statement, management policy. Stockholders value-oriented philosophy contributes to long-term growth and development of the firm as well as efficient equity financing and friendship with stockholder. IR is the key factor to attain successful implementation of company's objective. It should be equipped with the most suitable organization and qualified man-power for IR activities. The purpose of this study was to examine the relationship between IR and relationship marketing management. Strategic implications of this study are as follows: First, This study provides a new explanations of IR activities in Relationship Marketing Management.

This study examined the relationship between family socioeconomic status, emotional behavioral problems, parental composition, and parents' life satisfaction, all of which are factors that affect the life satisfaction of Korean middle school students. To this end, multi-group analysis was conducted on KCYPS panel data. The results showed four major patterns. First, family socioeconomic status has a significant direct effect on the students' life satisfaction only when the student has two parents and when the student's parents have high life satisfaction. Second, family socioeconomic status only significantly influenced students' emotional behavioral problems when parents had low life satisfaction, regardless of parental composition. Third, the mediating effect of emotional behavioral problems (aggression) in the relationship between family socioeconomic status and student life satisfaction was only significant when the student had two-parents and when the student's parents' had low life satisfaction. Fourth, depression was the variable most stronly correlated with student life satisfaction. This paper discusses the limitations of this study and the impliations of its results about how to improve students' life satisfaction.

This study investigated the effect of the grouping method in cooperative learning applied to chemistry concept learning. Two grouping methods used were the HML (High-Medium-Low) and the HL/MM (High-Low/Medium-Medium) ability grouping. Three classes (N = 136) at a high school in Seoul were randomly assigned to the control and the treatment groups. Before instruction. the test of attitude toward science instruction, the perception questionnaire of learning environment consisting of three subtests (participation, conflict, and competition), and the questionnaire of self-esteem were administered, and a mid-term examination score was obtained. These scores were used as covariates. After instruction, the three tests administered before instruction and the conceptions test were administered. Two-way ANCOVA results revealed that there was a significant interaction between the treatment and the level of previous achievement. The low-level students in the HL/MM cooperative group performed better than those in the other groups. The cooperative groups, regardless of the grouping methods, exhibited more positive perception than the control group at participation subtest of the perception questionnaire of learning environment.

The purpose of this study is to obtain basic data for constructing a modeling practice program integrated with meta-modeling knowledge by analyzing the cognition level for each meta-modeling knowledge components through modeling practice in the context of the chemistry discipline content. A chemistry teacher conducted inquiry-based modeling practice including anomalous phenomena for 16 students in the second year of a science gifted school, and in order to analyze the cognition level for each of the three meta-modeling knowledge components such as model variability, model multiplicity, and modeling process, the inquiry notes recorded by the students and observation note recorded by the researcher were used for analysis. The recognition level was classified from 0 to 3 levels. As a result of the analysis, it was found that the cognition level of the modeling process was the highest and the cognition level of the multiplicity of the model was the lowest. The cause of the low recognitive level of model variability is closely related to students' perception of conceptual models as objective facts. The cause of the low cognitive level of model multiplicity has to do with the belief that there can only be one correct model for a given phenomenon. Students elaborated conceptual models using symbolic models such as chemical symbols, but lacked recognition of the importance of data interpretation affecting the entire modeling process. It is necessary to introduce preliminary activities that can explicitly guide the nature of the model, and guide the importance of data interpretation through specific examples. Training to consider and verify the acceptability of the proposed model from a different point of view than mine should be done through a modeling practice program.

Match-3 Game 은 스테이지 구성 및 난이도 설정이 중요한 게임이나 다양한 밸런스 요소로 인해 스테이지 구성에 중요한 요소인 난이도 설정에 많은 시간이 소요된다. 특히 게임을 플레이하는 유저가 재미를 느끼는 수준으로 난이도를 설정하는 것이 중요하며, 이를 자동화하기 위해 실제 유저의 플레이 데이터를 활용하여 사람과 유사한 수준의 자동 플레이 에이전트 개발이 진행되었다. 하지만 플레이 데이터의 확보는 쉽지 않기에 연구 방향은 플레이 데이터가 없는 강화학습으로 확장되고 있다. 스테이지 구성에 중요한 요소인 난이도를 설정하기 위함이라면 각 스테이지 간의 상대적인 난이도 차이를 파악하는 것으로 가능하다. 이를 위해 게임의 규칙을 학습한 강화학습 에이전트로 밸런스 요소의 변화에 따른 다양한 난이도의 스테이지를 50 회씩 플레이하여, 평균 획득 점수를 기준으로 스테이지 구성에 필요한 각 스테이지들의 난이도를 파악할 수 있었다.
