This study has investigated the factors that make a science teacher effective by analyzing students' perception of teacher knowledge required in enhancing their science learning. The basic components of teacher knowledge identified by previous researchers have been confirmed through Exploratory Factor Analysis (EFA). Based on the findings of the EFA, the questionnaire has been further analyzed using Confirmatory Factor Analysis (CFA) by means of Structural Equation Modeling (SEM). In addition, the differences in students' perception on the identified factors of effectiveness have also been analyzed in terms of gender and achievement level. The findings of the EFA showed that five factors of science teacher effectiveness were identified; namely, substantive knowledge, syntactic knowledge, knowledge of students' understandings, knowledge of instructional strategies, and knowledge of assessment. These five components have been divided into two categories of teacher knowledge, SMK and PCK. What we found from the CFA was the respective high correlation between substantive and syntactic knowledge, knowledge of students' understanding and instructional strategies and the low correlation between substantive knowledge and knowledge of instructional strategies. Students perceived substantive knowledge as the most effective factor, knowledge of assessment as the least effective factor. Also, there have been considerable differences in students' perception by gender and achievement level. We proposed, based on the findings, that SMK and PCK need to be integrated into a coherent manner for the effective science teaching practice. This study provides some implications for science teacher professional development and the improvement of science teacher preparation program.

This study analyzed components of key competencies and its relations with Home Economics curriculum though literature analysis method. The literature total of 26 relating to key competencies is collected from two research institutes(KICE, KEDI) and two academic Journals(KSCS, KHEEA). The results show, first, every countries suggested different categories and components of key competencies according to classification of DeSeCo report(OECD, 2005). In subject matter, intellectual and learning capacities are emphasized; where as in inter-disciplinary or trans-disciplinary areas promoting character and competencies are focused. Second, ideal portraits of human being through home economics education is not closely related with those in a national curriculum. Third, achievement standards should be stated aligned with competencies, goals and curriculum contents, standards. Finally, there is a need to develop a curriculum design framework that teaching learning process incorporates knowledge, skills, and strategies relating other subject areas.

This study is a process of studying an alternative educational model and a preceding analysis process of the study where a teaching method considering the brain function, learning and creative mechanism is applied with a perspective of effectively increasing the animation drawing ability. Recently, studies in each field of study is not simply limited to one major but are attempting to produce subdivided integrated educational contents through integrated study activities with other fields. It is because for any field, it has a complex structure of humanistic experience and this is the same for artistic fields. Especially, in the field of animation, a specialized area is subdivided so when looking only at the education related to the drawing, the items required for expertise should be clarified and the development of a systematic educational method is required. Therefore in this study, a literature study result to design the educational model suitable for professional characteristics of animation education method is proposed. The study aims to conceptualize and categorize the meaning of drawing that can refine the basic ability for education of animation field to suit the characteristics of majoring field. Afterwards, the components are derived through re-established concept of drawing and categories, and this becomes the basis for the process of materializing the study goal which is the follow-up work. As a result, the components are examined by defining the meaning of drawing as the motion drawing due to the characteristics of the picture contents field, and used as a basis for planning the educational model applied with brain scientific creative-learning principles.

Bacterial infection of canine atopic dermatitis is largely caused by Staphylococcus intermedius and may be a superficial or deep pyoderma. The Purpose of this study was to identify the major proteins of S. intermedius cell surface components in humoral immune response of atopic dermatitis dog. Sera samples were obtained from dogs with atopic dermatitis and superficial pyoderma referred to the Veterinary Medical Teaching Hospital, Konkuk University. An isolate of S. intermedius from a clinical case of canine atopic dermatitis was cultured in brain heart infusion broth overnight at $37^{\circ}C$ in aerobic conditions on an orbital shaker. Following culture, Staphylococci were harvested by centrifugation, washed in PBS, and resuspended in PBS containing lysostaphin. The soluble components were separated by centrifugation and were collected. The soluble extract of S. intermedius was separated by sodium dodecylsulphate polyacrylamide gel electrophoresis (SDS-PAGE). The proteins were electrophoretically transferred onto nitrocellulose membrane. Western blotting for the specificity of serum IgG antistaphylococcal antibody was performed with anti-dog-IgG and sera obtained from an atopic dermatitis case and a normal dog. The molecular masses of four major proteins of S. intermedius recognized by serum obtained from an atopic dermatitis case were 18, 31, 75, and 110 kDa as determined by Western blot analysis. The present study indicates that most dogs of S. intermedius infection with atopic dermatitis could have a significant humoral immune response to bacterial proteins of the causative organism.

The magnetic field due to a current is one of the core concepts in electromagnetism which has been taught in secondary science education. In addition, it is a representative example of using visual representations to explain the relation between invisible physical quantities; current and magnetic field. In this study we investigated middle school students' representational competence into three components; interpretation, construction, and application of visual representations. According to the analysis, more than 75 % of the respondents interpreted the meaning of the arrows for current and magnetic field correctly. However, half of them confused the movement of electric charges with the direction of magnetic field. Over 60 % of the students constructed the magnetic field representation as circular closed curves, but many of them could not express the density of field lines properly. In application of visual representations, more than half failed to draw the direction of compass needle correctly. The scores were in order of interpretation, construction and application. There were also significant correlations among three components of representational competence. More attention and research on students' representational competence and effective use of visual representations is needed to better support science learning and teaching.

Purpose: Parents with a premature infant are usually confronted with difficulties in caring for their babies and need education on appropriate care. The purpose of this paper was to describe the components of caring education for parents with a premature infant based on an integrative literature review and to present strategies for future education. Methods: Four electronic databases were searched to identify studies. Sixteen articles were selected through full text screening of related research published in domestic journals from January 1990 to October 2012. Results: Through in-depth discussion and investigation of the relevant literature, three components emerged; (a) nurses as educators and parents as learners, (b) education content including caring on admission or discharge, and effects of education, and (c) education environment including timing, place and materials. Conclusion: Future education on caring for premature infant should include the nurse as educator and have diverse content including parent's role, interaction with healthcare providers, and special care for premature infants with special problems. Moreover, highly technical teaching materials should be provided, along with continuous support of institution and government to individual caregivers. Results of this study provide comprehensive prospective and basic standards for education on premature infant care.

The necessity of embracing selective courses in medical curriculum is increasing due to the expansion of medical knowledge and changes in the health care environment. In contrast to the abundant evidence regarding elective or selective courses during the clinical phase, articles focusing on the preclinical period are relatively scarce. This study aims to explore the development, implementation, and evaluation of newly-adopted selective courses in the first-year medical curriculum in a medical school which recently underwent a major curricular revision. First of all, the Curriculum Committee established goals and operating principles of the courses, and then the committee encouraged all participating professors to attend a related faculty development workshop after finalizing the list of courses. A survey was conducted at the end of each course for evaluation. Of the 36 courses opened in 2016, the overall satisfaction of students was $4.98{\pm}1.06$ (out of 6) and showed a strong correlation with students' previous expectations, reasoning- and participation-oriented teaching, and outcome of the courses including increased motivation. In the open-ended responses, students and professors described not only intended outcomes such as acquisition of medical knowledge and increased interest in new topics, but also unintended outcomes including positive impression for selective courses and even high satisfaction and rewarding experiences, especially from the teachers' perspective. Although long-term outcomes remain to be seen, the results of this study show the feasibility and impact of selective courses and will contribute to effective implementation in other medical schools.

Purpose: Hypertension has been a major cause of death in Korea since the 1970s, and has resulted in being a significant economic burden to the finances of national health care. The Ministry of Health and Welfare made several efforts. but hypertension control programs in Korea are still non standardized and ineffective. We wanted to investigate the current hypertension control program in public health centers systematically and suggest the direction for future programs. Method: The design of this study is a cross sectional investigation. From September to October in 2002, we sent a set of questionnaires to all PHCs, and 179 centers responded (response rate = 74.0%). The instrument was developed based on components of National health systems. Results: 1) Resources: The department responsible for hypertension control programs is the Department of Health Promotion. Health Education Center, Community Health Center, Citizen's Health Center, etc. The chief personnel of those departments are nurses. but 27.4% of PHCs have no full time nurse for hypertension management programs. PHCs had a lot of teaching materials (nine types per a PHC) and most of the recommended contents were included. But, periodical evaluation and revision were not being made, 2) Management: Nurses' (13.03 9.46 in 23 score) actions for hypertension control were not qualitative, but regular training and evaluation were seldom carried out. Need assessment (25.9%) and evaluation (about 10-20%) for the hypertension control program were indicated as low. 3) Programs: Programs focused on individuals rather than community or public, and 2nd prevention rather than 1st, 3rd prevention. Conclusion: The Ministry of Health and Welfare has to construct the infrastructure for hypertension control programs. Related scholars and committees should develop and declare standardized manuals for hypertension control and the management system, as well.

In the 2015 revised math curriculum, core competencies have been embodied and presented as skills and achievement standards. In this study, I analyzed aspects of the link between competencies, skills and achievement standards in the 2015 revised mathematics curriculum for elementary schools. According to the study, six mathematics curriculum competencies were presented evenly as 'skills' in each content area of elementary school, but reflected some of the sub-components of the curriculum, and some of them were presented as 'skills' but not as 'achievement standards'. In addition, the types of skills reflected in the achievement standards varied greatly by content area, but a few of specific skills such as 'understand' were found to be highly emphasized. Based on this, several implications were derived to further improve the implementation of competencies. First, 'skill' should be presented in a more systematic way and with more validity of extraction. Second, the extent to which competencies are presented in the achievement standards should be discussed. Third, Mathematics skills should be presented differently by grade(cluster) in achievement standards, 'Guidelines for Teaching and Learning' and 'Guidelines for Assesment'. Fourth, competencies related to content shall be presented separately and in detail.

The purpose of this study was three-folded to suggest the Simplifying Conditions Method (SCM) as a means of task analysis and sequencing of instructional content, to develop teaching-learning materials by analyzing part of the geological time scale of the earth science and finally to analyze the effectiveness of this method. SCM began by simplifying a complex task into the basic components by eliminating various complexities, which produced a simple representative of the entire task. The next step was to relax conditions on the basic version one by one, thereby gradually introducing progressively more complex tasks to the students. This sequential strategy enabled students to understand the task holistically and to acquire authentic skills from very onset of the course. Moreover, Early mastery of skills enhances the effectiveness and efficiency of instruction. The result of this study revealed that instruction through SCM was more effective in developing students' self-directed learning characteristics and academic achievement than instruction through sequential task analysis methodology.
