The objective of this study is to evaluate the current theory education system and students'awareness about Korean identity by analysing four-year curricula of Interior design programs in domestic universities and questionnaires of 468 junior and senior students who have taken the history of interior design. This study is the first step of continuous research for establishing new model of education related to Korean tradition. Following three issues - $\circled1$degree of knowledge and awareness of Korean university students majoring interior design about Korean identity, $\circled2$extent of the coverage of theoretical education for korean tradition in curricula of interior programs, $\circled3$extent of the application of Korean identity as a design theme in studio classes - were mainly analysed.

This study aims to investigate how the four college students interact with one another to discuss and construct meaning in a small reading group. Additionally, this study attempts to examine how the participants played their roles in the group. Data sources consisted of transcripts of the students' interactions, questionnaires and informal interviews, and the researchers' observation notes. The data revealed that the participants contributed fairly steadily to the interactions by checking with own grammatical knowledge, providing lexical information, understanding the micro level context, and presenting the macro level context. Several pedagogical implications are presented for the practical classroom. Findings of the study suggest effective ways to implement group activities in reading classes and a teacher's role for optimum group learning.

A study on the distribution and seasonal changes of the benthic macroinvertebrate community was performed on the 4 intertidal rocky shores of Biyang-do in Chehu Island throughout four seasons from January 1992 to january 1993. The macroinvertebrates composed of 8 phyla, 15 classes, 31 orders, 71 families, 168 species. The seasonal appearing species were 135 species in summer, 127 species in spring, 124 species in winter and 121 species in autumn, respectively. The dominant species of the upper zones were Nodilittorina exigua, Nerita japonica, Pollicipes mitella, the middle zones were Turbo coronata coreensis, Monodonta neritoides, petrolisthes japonicus and the lower zones were Pagurus samuelis, Chthamalus pilsbryi, Chlorostoma argyrostoma lischkei. The community dominance indices of the upper zones were much higher than the middle and lower zones. The seasonal appearnace in species in the lower zones were remarkable, but individual numbes were not. Species diversity and evenness in all investigated zones were highest in spring and lowest in winter. But species richness was highest in summer, lowest in autumm.

Generally, sequential data refers to data having continuity. Text data, which is a representative type of unstructured data, is also sequential data in that it is necessary to know the meaning of the preceding word in order to know the meaning of the following word or context. So far, many techniques for analyzing sequential data such as text data have been proposed. In this paper, four methods of 1d-CNN, LSTM, BiLSTM, and C-LSTM are introduced, focusing on neural network techniques. In addition, by using this, IMDb movie review data was classified into two classes to compare the performance of the techniques in terms of accuracy and analysis time.

The purpose of this study was to examine the effects of Korean traditional music education for young children on the development of musical attitude and rhythmic sense of young children. The subjects were 42 four or five-year-old children enrolled in two classes of a public kindergarten. Half were in the experimental and half were in the control group. Instruments were "Music Interest Test for Young Children" (Kim, 2000), "Musical Attitude Rating Scale for Young Children" (Ahn & Han, 1999) and "Primary Measures of Music Audiation" (Gordon, 1986). The procedure included pre-test, treatments and post-test paradigm. Experimental group had Korean traditional music activities three times per week, including listening, appreciation, singing, playing traditional instruments and creative movement. The control group was merely provided with materials related to the Korean traditional music. Data was analyzed by t-test. Results indicated significant differences in music attitude and rhythmic sense between the experimental group and the control group.

The purpose of this study is to analyze the effects of the use of calculators in elementary school mathematics education. For this purpose, we established the subject matters of the research as folloows; (1) to develop the lesson plan and the students' activity sheet related to the use of calculators. (2) to analyze the effects of the use of calculators when we applied the materials developed. Four classes of sixth grade students were sampled two elementary schools in D city. Two of them were assigned to the calculator group and the others to traditional group. The experiment was conducted for 10 class times. Two kinds of test instruments were used: pretest and post test. The pretest scores guaranteed that both groups were homogeneous. Post-test was used to identify the effect of use of calculator and the post-test scores were analyzed by t-test. We also used questionnaire to identify the students' change of attitude toward mathematics. The results of this study as fellows: (1) The calculator group got scores significantly higher than the traditional group on the test. (2) The students' attitude in calculator group was changed a little positively.

The purpose of this study was to classify the types of housing life style. Housing life style was measured using four variables : furniture usage pattern, space usage pattern, family living pattern and heating system. A final Instrument was developed through the two stage pilot surveys. The respondents were 1,292 home-makers of the middle and high economic classes In Seoul and Daejeon, selected through stratified random sampling technique. Data were analyzed using SAS computer packages. The statistics used were frequency, percentage, Pear-3on`s correlation coefficient, Multiple Linear Regression, X2, and cluster analysis.The major findings were as follows : Five representative types of housing life style were found through cluster analysis. They were conventional minimum level life style, conventional optimum famiIy-centered life style, eclectic family-centered life style, contemporary optimum family - centered and contemporary so-cial, leasure-oriented life style.

This study aimed to understand students' learning in elementary science classes in terms of participatory perspective. Participatory perspective is based on the participationist views on learning. Based on the participatory perspective, this study used two concepts of participationism: 'the changes of learning on commognition' of Sfard (2007) and 'the identity' of Wenger (1998/2007). Based on these concepts, four episodes of an elementary science class were analyzed. The results showed that students carried out their learning from objective-level learning to meta-level learning. And students defined who they are by identifying and negotiating scientific meaning during the learning. These results showed students become members of science community through their participations in science class.

The purpose of this study was to investigate the effect on the achievement of knowledge by animation-based learning program(ALP) in environmental education. The topic covered by ALP was "meaning and kinds of alien animals and plants". Four classes were selected and divided into two groups. The one was control group, and the other was treatment. 121 female the eighth graders(60 control and 61 ALP students) were piloted. Whereas control students learned using Powerpoint presentation-based materials, ALP students learned using web-based flash animations and animated database with images and movie clips. The score of knowledge achievement of ALP students was compared to control group students using ANCOVA, and then the score of ALP students was significantly higher than that of control group students(p<0.05). The ALP using animations and animated database was effective on the understanding of the alien animals and plants.
