The kinetic structure of the content of instructions at the unit of 'heart and circulation' in "the common science", which was respectively given by two teachers majored in biology and two teachers majored in earth science was investigated. Concerning of the mean of the fundamental coefficient (B1), the mean of weighted coefficients (B2) and the progression of instruction (P), T4 (B1, 0.14; B2, 0.82; P; 0.86) teacher showed relatively lower kinetic structure and faster progression than those of the others. The other teachers showed a different level of the kinetic structure and progression: T1(B1, 0.21; B2, 0.86; P; 0.79), T2 (B1, 0.02; B2, 0.85; P; 0.80), and T3 (B1, 0.22; B2, 0.83; P; 0.78). T1 teacher who showed the largest total frequency of verbal elements, the great number of sorts of verbal elements and secondary span, had a higher level of the kinetic structure, but T4 teacher showed the lowest level of total frequency of verbal elements, the great number of sorts of verbal elements and secondary span. The main reason why T4 teacher's instruction achieved a lower level of kinetic structure was estimated that he neglected to reorganize teaching materials and he showed a small number of discourse units. In addition, the unit of 'heart and circulation' was less related to T4 teacher's major and T4 teacher had a shorter teaching experience than those of the others. T4 teacher also took charge of only one class, and this did not allow to instruct repeatedly.

Sound Event Detection (SED) aims to identify not only sound category but also time interval for target sounds in an audio waveform. It is a critical technique in field of acoustic surveillance system and monitoring system. Recently, various models have introduced through Detection and Classification of Acoustic Scenes and Events (DCASE) Task 4. This paper explored how to design optimal parameters of DenseNet based model, which has led to outstanding performance in other recognition system. In experiment, DenseRNN as an SED model consists of DensNet-BC and bi-directional Gated Recurrent Units (GRU). This model is trained with Mean teacher model. With an event-based f-score, evaluation is performed depending on parameters, related to model architecture as well as model training, under the assessment protocol of DCASE task4. Experimental result shows that the performance goes up and has been saturated to near the best. Also, DenseRNN would be trained more effectively without dropout technique.

Computer with various powerful functions has profound potential for mathematics instruction and learning. As computer technology progress, its applicability to mathematics education become more comprehensive. Not only its functional development but various psychological positions also changed the way computer technology utilized in mathematics education. In behaviorist's perspective, computer viewed as a teaching machine and constructivist viewed computer as microworld where students could explore various mathematical contents. Both theoretical positions emphasized individual aspect of learning because behaviorist tried to individualize learning using computer and constructivist focused on the process of individual construction. But learning is not only a individual event but also a social event. Therefore we must take social aspect into account. This is especially important when it comes to computer based learning. So far, mathematics loaming with computer weighed individual aspect of loaming. Even in microworld environment, learning should be mediated by teacher and collaborative learning activities. In this aspect, the roles of teacher and peers are very important and socio-cultural perspective sheds light on the computer based learning. In socio-cultural perspective, the idea of scaffold is very important in learning and students gradually internalize the social dimension and scaffolding is gradually faded. And in the zone of proximal development, teacher and more competent peers guide students to formulate their own understanding. In sum, we must take following points into account. First of all, computer should not be viewed as a medium for individualized teaming. That is, interaction with computer should be catalyst for collaborative activities with peers. So, exploration in computer environment has to be followed by small group activities including small group discussion. Secondly, regardless of the role that computer would play, teacher should play a crucial role in computer based learning. This does not mean teacher should direct every steps in learning process. Teacher's intervention should help student construct actively. Thirdly, it is needed to conceptualize computer in learning situation as medium. This would affect learning situation and result in the change of pre-service and in-service teacher training. Computer to be used effectively in mathematics classroom, researches on assessment of computer based learning are needed.

The specific objectives of this study were at follows. 1. To determine and compare the perceptions of home economics teachers and teacher educators regarding the importance and achievement of (1) the objectives of student teaching, (2) the experiences of student teaching, (3) procedures for selecting cooperating teachers, (4) roles and responsibilities of cooperating teachers, and (5) roles and responsibilities of university supervisors. 2. To identify problems and revisions about home economics student teaching pratice suggested by home economics teachers and teacher educators. The subjects in this study included 90 home economics teachers in 500 girls’middle schools and 13 teacher educators in 21 universities with home economics education department in Korea. For this study, the Habedi’s instruments were used through testing validity and reliability. The data of this study were analyzed by using mean, standard deviation, t-test, and content analysis. The results of this study were as follow；1. The areas with the difference of perceptions of the importance between the two groups were objectives of student teaching, experiences of student teaching, procedures for selecting cooperating teachers, and roles and responsibilities of cooperating teachers. 2. Regarding problems about home economics students teaching practice, home economics teachers indicated difficulty in performing adequate student teaching because of reduction in class hours, and lack of student teachers’positive attitude in performing student teaching, while teacher educators indicated having reluctancy of cooperating school to admit student teachers, and difference in experiences of student teachers because of disparity among cooperating schools. As solutions about the problems of home economics student teaching practice, home economics teachers suggested that student teaching course should be limited to the students qualified for teaching and that class observation and teaching practice in real class should be emphasized, while teacher educators suggested that student teaching should be performed adequately by providing institutions to control student teaching practice teacher should be made efficient by examining the scales of cooperating schools.

The purpose of this study was to investigate the high school teachers' sexual knowledge, attitude and their need of sex education for the students in Seoul. These data were collected by questionnaire in Oct. 1989. The result was compared by the type of teacher (school health nurse and high school teacher), involving in sex education or not, age, marital status and religion. The major findings of this study were as follows: 1. The mean score of sexual knowledge of the school health nurses was higher than the high school teachers. (P<0.05) (the average correct answer rate:the school health nurses=80.85%, the high school teachers=62.65%)Female teachers who were involved in sex education got higher score than the male high school teachers and female teachers who were not. (P<0.05) The married female high school teachers got higher score than never-married. (p<0.05) 2. About the sexual attitudes, the respondents were asked in the Likert's four-point scale with 3 groups of questions that were anatomical and physiological terminology about sex, normal sexual life and immoral sexual life. About anatomical and physiological terminology about sex, they had a little positive feeling. (mean score= 2.62) The school health nurses and the male high school teachers had more positive feeling than the female. (P< 0.05) Also the aged and married male high school teachers had more positive feeling than others. (P<0.05) About normal sexual life, they had a little positive feeling and moderately permissive attitude. (feeling mean score=2.96, attitude mean score=3.23) The school health nurses and the male high school teachers had more positive feeling than the female. (P<0.05) And the male high school teachers had more permissive attitude than the female. (P<0.05) About immoral sexual life, they had strongly negative feeling and conservative attitude. (feeling mean score =3.49, attitude mean score=3.35) The school health nurses the female high school teachers had more negative feeling and conservative attitude than the male. (P<0.05) And the male protestant high school teachers had more conservative attitude than no-religion group. (P<0.05) 3. There was a weak correlation between sexual knowledge and attitude. 4. There was no significant difference about starting of sex education between the school health nurses and the high school teachers. (P>0.05) Generally, they answered that the starting of sex education about physical growth and development could bp given with the students' physical growth and development. But for the sex education about emotional and social development, they answered that the education should be given later than the emotional and social development of students. 62.1% of the school health nurses did sex education and 36.5% of the high school teachers did. The common contents of sex education were intersexual-fellowship(date), venereal disease and marriage. And the education about abnormal sex-behavior. divorce and sexual intercourse was given rarely.

Purpose: The purpose of this study was to investigate predictors of behavior problems of military children in elementary school. Methods: Participants were 195 military children who were attending D-elementary school in C-city. Data were collected from July 8 to July 10, 2013, using self-report questionnaires which included Han's Externalized Behavior Problems Scale, Lee's Parent's Rearing Attitude Scale, and Hong's Friend/Teacher Support Appraisal Scale. Data analysis was performed using the SPSS/WIN 18.0 program, which included the t-test, the one-way ANOVA, Pearson correlation coefficients, and the multiple liner regression analysis. Results: The mean score of the subjects' behavior problem was 1.47/5.0 points. The degree of the score is similar to or slightly lower than that of ordinary children. There were statistically significant differences in behavior problems according to gender, grade, birth order and economic status. Behavior problems have a negative correlation with parent's rearing attitude, parent-child relationship, teacher's support, and friend's support. Influencing factors of behavior problems were teacher's support, father-child relationship, and mother's rearing attitude, which explained 20.6% of the variance. Conclusion: The finding of this study suggests there is a need to increase teacher's support for elementary students and to educate parents to improve their parenting skills by developing proper school health programs.
