Objective and subjective methods were performed together for TPA analysis of acorn mook, and their correlations were analyzed. As the result of sensory evaluation, hardness and fracturability were most important factors for prediction of preference. Meanwhile, compression test with Instron Universal Testing Machine revealed that P1(maximum peak in first bite) was very effective factor representing the cheracteristics of first bite, and that P2 the latter peak in first bite) was valuable for prediction of characteristics of second bite.

Introduction：Test anxiety is a pervasive problem among high school students in Korea. While anxiety in test situations may actually facilitate the performance of some students, more often it is disruptive and leads to performance decrements. Over the past years, many child psychiatrists have become concerned with understanding the nature of test anxiety, but it is not clearly understood yet. In order to understand the nature of test anxiety, the relationship between test anxiety and depression, state anxiety, trait anxiety, temperament and family environment were examined. Methods：The Test Anxiety Inventory, Chidlren's Depression Inventory, State-Trait Anxiety Inventory, Temperamnet and Family Environment Scale Scale were administered to 576 high school students in Seoul. The relationships between test anxiety and other measures were tested using Pearson correlation coefficients and to test the causal relationship among the variables, regression analysis was performed. Results：The correlation coefficients between test anxiety and depression, state anxiety, trait anxiety, temperament and family environment scale were 0.42(p<0.01), 0.34(p<0.05), 0.38(p<0.05), 0.36(p<0.05) and -0.23(p<0.01), respectively. Regression analysis showed that only state and trait anxiety had direct causal relationship with test anxiety. Depression, temperament and family environment were indirecly related with test anxiety. Conclusions：This study indicates that the level of state and trait anxiety are directly related with test anxiety, and other variables such as temperament, family environment and depression are indirectly related with test anxiety. Thus, in order to develop the effective methods for treatment, these psychopathological characteristics should be kept in mind and the most important factors are the levels of state and trait anxiety.

The purpose of this study was to compare communication and mother-child interactions of reactive attachment disordered children with normal children. The subjects were 24 children and their mothers participated in this study'12 reactive attachment disordered children and mothers, 12 normal children and mothers. The mother and her child were brought into a p]lay room and the mother was instructed to play with her child as she normally would at home. The play situations were videotaped. Tapes were transcribed and transcribed data was analyzed with 13 mutually exclusive categories encompassing pragmatic functions represented in communication form the early stage of multiword speech in childhood. The tapes were analyzed with 10 behavioral mother-child interaction patterns. As the statistical method, t-test and correlation was calculated. The results of this study were as follows : 1) Reactive attachment disordered children used significantly fewer 'filler', 'information', 'requests', 'describes' and 'disscus self'. 2) Reactive attachment disordered children's mother used significantly fewer 'filler' and 'names'. 3) Reactive attachment disordered children used significantly more 'independent play', fewer 'intiates interaction', 'responsiveness' and 'answer' Reactive attachment disordered children's mother used more 'control play', 'observe' and fewer 'initiates interaction'. 4) Children's communication patterns were related lo mother·'s communication and mother-child interaction types. Children's 'filler', 'information requests', 'describes' and 'disscus self' were consistantly related to mother's 'filler' and 'names', (Children's 'filler', 'information requests', 'describes'. 'disscus self' and mother-child's intiates interaction 'responsivness' were significantly positively correlationed and 'independant play', 'control play', 'observation' were significantly negatively correlationed. The results of reveal that communication and mother-child interaction pattern of reactive attachment disordered group was different from normal group and children's communication pattern were influenced by mother's communication and interaction patterns.

This study examines the relationship between teacher-perceived teaching efficacy and happiness and teacher-infant interaction, and analyzes the effect of teaching efficacy and happiness on teacher-infant interaction. The purpose was to reveal that it was an important variable in the quality of action. Frequency analysis and descriptive statistics analysis were conducted for the Korean Children's Panel 7th year (2014) data, and Pearson's moment-moment correlation coefficient was calculated for correlation analysis between variables. Multiple regression analysis was conducted to examine the influence of teachers' teaching efficacy and happiness on teacher-infant and infant-infant interactions. The research results were as follows. First, teachers' teaching efficacy, teacher happiness, teacher-infant, and infant-infant interactions were all found to have significant positive correlations. Second, teachers' teaching efficacy was found to have a significant effect on teacher-infant and infant-infant interactions, and the influence increased when teacher's happiness was added. Therefore, we need to come up with a plan to increase teachers' teaching efficacy and teacher happiness at the same time so that the quality of teacher-infant and infant-infant interactions can be meaningfully improved.

This study aims at developing a method for estimating passenger car equivalency (PCE) values for various vehicle types that could be considered in estimating capacity and delay at intersections without traffic signals, especially at modern small 3-leg roundabouts. Unlike signalized intersections, the PCE value has not yet been treated explicitly in traffic operations involving unsignalized intersections. Both empirical and theoretical approaches for determining the PCE values at modern small 3-leg roundabouts were evaluated. As a result, the PCEs derived in this study were highly correlated with those of field measurements.

Recent development and penetrating expansion in ICT(Information and Communication Technology) has brought considerable improvements in transportation services. However, there is a controversial debate whether transportation and communications behave as substitutes or as complements to one another. On this subject, recent studies considered those two industries as services, but transportation and communications are broadly put for intermediary goods into other industries. Hence, it is essential to examine this issue from understanding their relationships to each other with respect to manufacturing and services. In this study, input-output tables of benchmark years from 1980 to 2005 have been analysed to explore the relationships between transportation and communications using Spearman's correlation analysis. The results show that both industries had complementary roles over the period, but, to some extent, changed into substitution roles in some categories.

The purpose of this study is to identify the relationships among childcare teachers' emotional intelligence, daycare center directors' emotional leadership, and teacher-infant interactions. Also, this study examines whether a daycare center director's emotional leadership would mediate the correlation between a childcare teacher's emotional intelligence and teacher-infant interactions. A questionnaire was given to 293 childcare teachers. Using SPSS version 21.0, the data were analyzed for Pearson's correlation, hierarchical regression analysis, the Sobel-test, and the meditation effect proposed by Baron and Kenny. The findings are as follows. First, there was a positive correlation between a childcare teacher's emotional intelligence, the director's emotional leadership, and teacher-infant interactions. Second, the influence on teacher-infant interactions from directors' emotional leadership was relatively greater than childcare teachers' emotional intelligence. Finally, the emotional leadership of daycare center directors partially mediated the relationship between childcare teachers' emotional intelligence and teacher-infant interactions. This study provides significant empirical data for improving childcare.
