This study analyzed research trends in the field of Practical Arts (Technology & Home Economics) education. From 958 articles published between 2010 and 2018 in the Journal of Korean Practical Arts Education (JKPAE), Journal of Korean Home Economics Education Association (JHEEA), and Korean Journal of Technology Education Association (KJTEA), 958 keywords were extracted and analyzed using NetMiner 4. When the general network structure was analyzed, keywords such as practical arts education, curriculum, textbook, home economics education, and students were high in the degree centrality and closeness centrality, and textbook, practical arts education, curriculum, student, home economics education, and invention were high in the node betweenness centrality. The cluster analysis showed that a four-cluster solution was most appropriate: cluster 1, technology and experiential learning activities; cluster 2, curriculum studies and practical problem; cluster 3, relationships; and cluster 4, creativity and character education. The three journals showed differences in the knowledge network structure: The topics of JKPAE and JKHEEA focused on general content knowledge and curriculum, while the topics of KJTEA were spread across invention and creativity education, and curriculum studies.

The purpose of this study is to clarify the specific terms of epistemic and epistemological by reviewing the literature on epistemological understanding of science learning, examine the necessity of epistemic discourse analysis based on the view of social epistemology, and provide an exemplar of practical epistemology analysis for elementary children's science learning. The review was conducted in terms of meaning and terminology about epistemic or epistemological approach to science learning, epistemology of/for science, and methodologies for epistemic discourse analysis. As an alternative way of epistemic discourse analysis in science classroom I employed practical epistemology analysis (by Wickman), evidence-explanation continuum (by Duschl), and DREEC diagram (by Maeng et al.). The methods were administered to an elementary science class for the third grade where children observed sedimentary rocks. Through the outcomes of analysis I sought to understand the processes how children collected data by observation, identified evidence, and constructed explanations about rocks. During the process of practical epistemology analysis the cases of four categories, such as encounter, stand-fast, gap, and relation, were identified. The sequence of encounter, stand fast, gap, and relation showed how children observed sedimentary rocks and how they came to learn the difference among the rocks. The epistemic features of children's observation discourse, although different from scientists' discourses during their own practices, showed data-only conversation, evidence-driven conversation, or explanation inducing conversation. Thus I argue even elementary children are able to construct their own knowledge and their epistemic practices are productive.

Importance of using an injection molding analysis has been increased. However the application of it has not been increased because the results of analysis do not sometime match to practical molding. Therefore, the difference of flow analysis and practical molding should be decreased. This study presents reasons of the difference for the location of weld-line in the flow analysis and practical molding on automobile bumper molding.

This study aims finding a desirable practical skill evaluation practice evaluation method and then improving student’s learning effect by analyzing the present state and the methods of practical skill evaluation in middle-high schools home economics education. Investigated persons are 250 of high schools home economics thachers(125) and middle schools home economics teacher(125) in Seoul, who are choosen by means of random sampling. The items analysis of questionnaires was performed by means of SPSS(Statistical Package for Social Science). The investigator analyzed their responses to the questionnaires according to teachers’ages, school careers, majors, places of employment, school years in charge. The results are marked with percentage and the significance level is verified by means of Chi-square(X$\^$2/) analysis method, when necessary. This thesis handles practical skill evaluation of general practice units, of clothing and textile unit, and of nutrient and food unit. The results obtained from the items analysis are as follows; I. Results of the items analysis. A. Practical skill evaluation of general units. 1. The motivation and accomplishment feeling of students are most frequently considered as the aims of practical skill evaluation, but the results of practical skill evaluation are, by contraries, most infrequently considered as improvement materials. 2. A greatest number of teachers make together with their colleagues an annual plan for practical skill evaluation an inform students of the concrete information of the test, but perform respectively practical skill evaluation, using 5 steps method. 3. The percentage that teachers majoring in home economics education as compared with others lay the similar stresses on the preparation processes, attitudes, and results of students is very high.

This study is conducted to examine the relationship between salespeople's job consciousness, their competencies of practical business and their turnover intention in department stores. The data was collected from 1961 department stores salespeople in Seoul and Sungnam. And a survey was conducted by questionnaire. Mean, Scheffe-test, Cronbach's ${\alpha}$, Perason's correlation, factor analysis, regression analysis, path analysis are used for the analysis of data. Major findings are as follows : 1) Job consciousness of salespeople is relatively strong, the level of competencies of practical business and turnover intention are somewhat low. 2) Job consciousness of salespeople and their competencies of practical business are related to their turnover intention. The more strongly they have job consciousness, the more highly they have the level of competencies of practical business, and the lower their turnover intention becomes. 3) Among related variables, their perception of distributive education shows the strongest effect on job consciousness of salespeople. Their job consciousness shows the strongest effect on competencies of practical business. Their job consciousness and competencies of practical business show the strongest effect on turnover intention of salespeople. 4) Turnover intention of salespeople is affected by the job consciousness directly or indirectly, and by competencies of practical business directly. Among related variable, age, experience degree on distribution education, period of work, educational level, marital status, jobs, the motive of choosing their occupation and sex show only indirect effects on their turnover intention through job consciousness and competencies of practical business of salespeople. The motive of choosing their occupation, importance degree on distributive education, sections of department stores(Clothing), perception degree on job specialization and selling experience show only direct and indirect effects on their turnover intention. Thus, job consciousness and competencies of practical business of salespeople are the major intervening variables which have strong negative effects on their turnover intention.

This study investigated the practical use of educational subjects and contents of materials in the fashion industry field and analyzed all data from respondents depending on business area and years of work in order to develop appropriate educational methods and courses. The survey was conducted with 151 questionnaires; 148 responses were used in the data analysis. The statistical analysis methods were frequency analysis, factor analysis, and ANOVA. The factors of educational subjects for Clothing and Textiles were classified into three categories of product planning, manufacturing and basic information, and manufacturing-related subjects (including materials); subsequently, these showed a high practical use in the fashion business. There were significant differences in the practical use of educational subjects that depended on business areas and years of work for respondents. In the case of education of materials, the contents of fibers, knit fabrics and textile planning were used the most in various business areas; in addition, there were also significant differences in the practical use of knits, textile care, textile planning and trade, and textile retailing depending on business area.

The purposes of this study are to investigate the relationship between the Piaget’s cognitive developmental theory and the practical course subject in elementary school which have the characteristics of skillful subject and living subject, and to discriminate the suitability of contents of the practical course subject for the childrens’level of cognitive development. This work could serve the theoretical background that the practical course subject presents practical experiences which lead the development of logicomathematical thinking abilities. The results of the content analysis shows that create activities develop the logicomathematical thinking abilities such as projective geometry, topology geometry, area conservation, length & distance conservation, and volume & mass conservation. And the most contents of the practical course subject are suitable for the childrens’level of cognitive development.

Teacher's practical knowledge is potentially relevant to the teaching practice in his/her classroom. The research explored early childhood teachers' practical knowledge of 'curriculum' via conceptual metaphors. The participants (N=348) completed a prompt, "Curriculum is like A because B" and then the metaphors were analyzed according to the procedure proposed by Moser (2000). The analysis found that 8 themes (i.e. 'educational basis', 'learning opportunity', 'educational material', 'difficulty', 'change', 'pre-determination', 'discordance', and 'reconstruction') were the underlying conceptions signified in those metaphors. The implications regarding early childhood teachers' practical knowledge were discussed on the perspective of post-modern curriculum. Moreover, it recommended the practical knowledge based approach for early childhood teacher education, and transformation of current policy for program evaluation relevant to curriculum conceptualization.

Most structures of automobile are composed of many substructures connected to one another by various types of mechanical joints. In automotive engineering, it is important to study these connected structures under various dynamic farces for the evaluations of fatigue life and stress concentration exactly. It is rarely obtained the accurate load history of specified positions because of the errors such as modeling, measurement, and etc. In the beginning of design, exact load data are actually necessary for the fatigue strength and life analysis to minimize the cost and time of designing. In this paper, the procedure of practical dynamic load determination is developed by the combination of the principal stresses of F.E. analysis and experiment. Inverse problem and least square pseudo inverse matrix are adopted to obtain an inverse matrix of analyzed stresses matrix. Pseudo-Practical dynamic load was calculated for Lab. Test of sub-structure. GUI program(PLODAS) was developed for whole of above procedure. This proposed method could be extended to any geometric shape of structure.
