This Study focused on understanding the relationship between the child ren's thinking ability which is based on the genius and the parenting attitude according to their level of age. There were 401subjects including mothers and their children who lived in Seoul city ages from four to six. The Raven CPM testing method for children and the parenting attitude test were used as research tools. Subcategories of the parenting attitude test consisted of the supportive expression, the rational explanation, the achievement press, high involvement, punishment, superintendence, high expectation, and inconsequence. Results showed that by age four children's thinking abilities were affected by the rational explanation, the achievement press, punishment, and superintendence. At age five, the supportive expression and superintendence were important factors to the thinking ability. By age six children were affected by the supportive expression, the rational explanation, punishment and high expectation. It was also discussed the positive or negative effects of the parenting attitude sub-scales to the development of the thinking ability. These results showed the parenting attitudes need to be changed according to the child's age for getting more resonable results to their children's thinking ability.

The aim of this study is to explore diverse characteristics of females aged 25 to 49 years grouped according to Body Mass Index(BMI), and to investigate the effect of body satisfaction and self-esteem on involvement in dieting within each BMI group. In total, 549 females who participated in an online survey were divided into groups based on BMI(underweight, normal, and overweight). Results demonstrated three key factors, as follows. First, differences were identified among BMI groups according to demographic characteristics(age, household income, and marital status), although no difference according to education level was found. Second, differences according to BMI groups were found in body satisfaction and involvement in dieting, whereas were not found in self-esteem. Third, model testing for each BMI group showed, a positive correlation between body satisfaction and self-esteem in all three groups. However, there was a difference in causal relationships among variable across BMI groups. Body satisfaction negatively affected and self-esteem positively affected involvement in dieting for the underweight and normal groups, whereas there was no causal relationship between variables in the overweight group. Based on these results, basic information of groups segmented by the level of BMI was obtained, which could be used for both academic and practical implications.

According to the Infant Educational Law, learning of the children are encouraged through playing, but there are not many tools to learn. Educational Serious Game is a game developed for the purpose of learning. And so, in this paper, we produced serious games for education learning for young children. Contents of the game is the digestive system. And we utilized touch and drag which are kinds of intuitive interface of the mobile platform being able to play easy. At the end of each stage, and it contained a scene that can learn the characteristics of the digestive system. After producing this game, we supplemented something that is inadequate through testing. In addition, the learning effect of the game was confirmed by interviews with the teachers. We hope this will be a fun and informative game for the digestive tract to the children.

The instruction based on mass production system has contributed to the materialistic abundance, but it caused the innate target of education, development of 'holistic human beings' to be lost. Accordingly, the mentoring has been highlighted as an alternative instructional method because it can support learners in the aspect of cognitive and affective domain. On the other hand, as an effort of overcoming time and place constraints of face-to-face mentoring, e-mentoring is being required. This research aims to propose the e-mentoring system design plan for guiding learning after school, which may support face-to-face mentoring. Based on literature reviews, the direction of design was set and the necessary functions were drawn. e-Mentoring system design plan proposed in this article may be helpful to practitioners who are interested in the enhancement of effectiveness and efficiency of mentoring programs. Also it is required that more practical study should be performed for developing the system and testing its effectiveness.

This article is to estimate the fishing frequency function in Korean recreational fishery with respect to socio-economic characteristics of anglers. First, the study described the characteristics of the entire angler population on the view points of 9 socio-economic variables. And then, the study divided the total angler population into three groups of in-land, sea, and mixed angler populations in order to investigate the differences in their characteristics. The study could confirm the existence of differences in regions, size of regions, and educational levels between the in - land and the sea angler populations by testing heterogeneity in the frequency table. The fishing frequency function is estimated using Poisson regression model in order to accomodate the count data(non-negative discrete random variable) aspects of the fishing frequency. However, the model specification error is found due to overdispersion of data. The model exhibits the lack of goodness of fit. The negative binomial regression model is adopted to cure the overdispersion of the data as an alternative estimation methodology. Finally, the study can confirm overdispersion does not exist in the model any more and the goodness of fit improved significantly to the reasonable level. The results of estimation of fishing frequency population modeled by the negative binomial regression models are following. The three variables of region, sex, and education have effects on the decision making process of fishing frequency in the case of in-land recreation fishery. On the other hand, the three variables of sex, age, and marriage status do the same job in the case of sea angler population. Among the left-over variables, both income and use of Internet variables now affect on the process in mixed angler population. Finally, the results of whole angler population show that all of the previous variables are proven to be statistically significant due to the summation of data with all three sub-groups of angler population.

Contingency tables are used to compare counts of n-grams to determine if the n-gram is a true collocation, meaning that the words that make up the n-gram are highly associated in the text. Some statistical methods for identifying collocation are used. They are Kulczinsky coefficient, Ochiai coefficient, Frager and McGowan coefficient, Yule coefficient, mutual information, and chi-square, and so on. But the main problem is that these measures are based ell the assumption of a nor-mal or approximately normal distribution of the variables being sampled. While this assumption is valid in most instances, it is not valid when comparing the rates of occurrence of rare events, and texts are composed mostly of rare events. In this paper we have simply reviewed some statistics about testing association of two words. Some randomization tests to evaluate the significance level in analyzing collocation in large corpora are proposed. A related graph can be used to compare different lest statistics that ran be used to analyze the same contingency table.

The purpose of this study was to explore college students' use of learning strategies in a flipped learning class, and to examine the students' use of learning strategies in relation to their achievement levels. The participants were 33 college students who took an introduction to English education course. The study used three data collection procedures: (1) students' performance score; (2) a pre-and post-survey of student learning strategies; (3) a survey of student perception towards the flipped learning experience. Data were analyzed by using paired samples t-test and ANOVA. Results showed that the students used different learning strategies in the beginning and the end of the course, depending on their achievement levels. In particular, significant differences were found among three groups in terms of time management, concentration, selecting main idea, self-testing, and test strategies. The result indicates that learning strategies can be effectively trained and developed in the flipped learning environment with the consideration of students' levels.

Purpose: The purpose of the study was to survey male high school students on their MERS(Middle East Respiratory Syndrome)-related knowledge, risk perception, and health behaviors and to identify the factors affecting health behaviors during the MERS outbreak in Korea. Methods: The subjects in this study were 144 students in a male high school. Data were collected through self-reported questionnaires in July, 2015. The collected data were analyzed by ANOVA, Pearson's correlation and multiple regression using SPSS/WIN 21.0. Results: The proportion of correct answers to questions testing MERS-related knowledge was 71.6% among male high school students; their health behaviors were rated at 48.9%; and their risk perception rate was 1.8 out of 4. There was a positive correlation between knowledge, risk perception, and health behaviors. Knowledge and risk perception explained 15.1% of the variance in health behaviors. Conclusion: To improve students' health behaviors, their risk perception and knowledge over MERS should be strengthened. Therefore, it is necessary to develop and implement efficient and feasible MERS education programs for high school students.
