The foster care system is a social welfare service that supplements the functions of the family while enabling children, who cannot receive proper care from their biological parents, to receive the necessary protection under the plan within the prescribed period of time within a substitute or foster family. A large part of the emotional instability experienced by foster care children is interpersonal maladjustment. Low self-esteem leads to difficulty in forming social relationships due to negative interpersonal relationships. Thus, the purpose of this study is to investigate the effects of traditional dance programs on the foster children who live in Daejeon Metropolitan City. A comparison between the pre- and post-interpersonal scores showed that the scores were improved after the traditional dance program, and the children's intimacy formation and communication were also improved. The participants were less active at the beginning of the program, but became more interested and more active toward the middle of the program. The majority of the participants increased their degree of communication with the formation of intimacy toward the middle of the program, and their self-confidence improved in terms of their peer relationships. The purpose of this study was to investigate the effects of traditional dancing on the development of interpersonal relationships. In a subsequent study, a traditional dancing program consisting of various contents will be applied over a long period of time, which should provide them with the opportunity to improve their interpersonal skills. In addition, it is necessary to provide educational opportunities for helping foster children reduce their emotional instability with systemic and diverse traditional dance programs.

While there have many completions of large parks recently under development, there has been a dearth of quality assessments. Studies focused on post-evaluation have been made to resolve this, but most of these are biased toward user satisfaction after completion and therefore behaviour analysis has limitations on solving problemsduring the actual design implementation processes. Therefore, this study examined the internal phenomenon and structure of the implementation process of design competition through the ground theory and microscopic independent perspective. As a result, maintaining the identity and differentiation of parks derived from the preserved design competition scheme contributed greatly to completeness and satisfaction. Outcomes were mainly caused by the trust of public officials as the ordering organization, the will of policy decision-makers, and the competence of operational enterprises, etc. Negative factors such as undermining the whole concept of the park and landscape occurred as external pressure and related subjects intruded on change design factors due to variations in social conditions. Additionally, illogical construction processes occurred, such as a reinvestigation of the budget for restoration after damaging on original landscape. There have been needs for the improvement of the work processing system. On balance, an interventional role is very important in the park construction process, especially the PA and operation committee in terms of maintaining the basic direction, landscape design supervision for detailed designs, and expert construction management on LA in terms of rational work management in the field. The study, using the microscopic perspective of the designer and ground theory, deliver significant meaning as an early study by suggesting alternative methods for the after-evaluation of large parks and structurally looking into main influence factors driven during the construction process.

The purpose of the study was to investigate the perceptions of Elementary school teachers on mathematics instruction. To do this, 7 test items were developed to obtain data on teacher's perception of mathematics instruction and 73 teachers who take mathematical lesson analysis lectures were selected and conducted a survey. Since the data obtained are all qualitative data, they were analyzed through coding and similar responses were grouped into the same category. As a result of the survey, several facts were found as follow; First, When teachers thought about 'mathematics', the first words that come to mind were 'calculation', 'difficult', and 'logic'. It is necessary for the teacher to have positive thoughts on mathematics and mathematics learning, and this needs to be stressed enough in teacher education and teacher retraining. Second, the reason why mathematics is an important subject is 'because it is related to the real life', followed by 'because it gives rise to logical thinking ability' and 'because it gives rise to mathematical thinking ability'. These ideas are related to the cultivating mind value and the practical value of mathematics. In order for students to understand the various values of mathematics, teachers must understand the various values of mathematics. Third, the responses for reasons why elementary school students hate mathematics and are hard are because teachers demand 'thinking', 'because they repeat simple calculations', 'children hate complicated things', 'bother', 'Because mathematics itself is difficult', 'the level of curriculum and textbooks is high', and 'the amount of time and activity is too much'. These problems are likely to be improved by the implementation of revised 2015 national curriculum that emphasize core competence and process-based evaluation including mathematical processes. Fourth, the most common reason for failing elementary school mathematics instruction was 'because the process was difficult' and 'because of the results-based evaluation'. In addition, 'Results-oriented evaluation,' 'iterative calculation,' 'infused education,' 'failure to consider the level difference,' 'lack of conceptual and principle-centered education' were mentioned as a failure factor. Most of these factors can be changed by improving and changing teachers' teaching practice. Fifth, the responses for what does a desirable mathematics instruction look like are 'classroom related to real life', 'easy and fun mathematics lessons', 'class emphasizing understanding of principle', etc. Therefore, it is necessary to deeply deal with the related contents in the training courses for the improvement of the teachers' teaching practice, and it is necessary to support not only the one-time training but also the continuous professional development of teachers.

This study aimed to identify influencing factors such as job environment, job characteristics, and job competency as they are related to newcomer turnover intentions in the construction of landscape architecture, Korea. The results based on statistical analyses are follows as: The turnover experience of newcomers in the field of landscape architecture construction was 54.5%, about 1.6 times higher than in other fields. The influencing factors among newcomer turnover intentions in the construction of landscape architecture were workload(p<0.01), job suitability, and personal relations(p<0.01), while in job autonomy, work conditions, job competency, job identity, job variety, and job compensation were not statistically significant. This study found that key important factors of dependent variables that conceptually explain the influence of turnover intentions among newcomers differed between the construction of landscape architecture and other fields. The most important factors in turnover intention were workload>personal relationship>job suitability among independent factors. This study implied that efforts for improvement are needed in areas of workload, personal relations, and job suitability to mitigate newcomer turnover intentions so as to establish common and personal goals in the field of landscape architecture construction because turnover intention could lead losses in human resources, time, economy, and psychological health. In conclusion, this study suggested the importance of efforts for human resource management to reduce turnover intentions among newcomers in the field of landscape architecture construction.

The purpose of this study was to analyze reports from research middle schools based on the criteria for process-focused assessment to find out how the characteristics of process-focused assessment were being implemented in middle school science classes. The analysis criteria for the characteristics of process-focused assessment (integration of lessons and assessments, evaluation elements and methods, content and timing of feedback, and learner growth management) were extracted. Using the analysis framework, the result reports of seven research middle schools for process-focused assessment were analyzed. In terms of integration of lessons and assessments, when the process-focused assessment was operated, the class and evaluation plan were well implemented based on the curriculum achievement standards, but the process-focused assessment was recognized as a performance evaluation. In terms of evaluation elements and methods, the evaluation element for knowledge was the main component, and competency was presented in the planning stage, but competency was not dealt with in class execution. The evaluation method was biased toward teacher-centered observation evaluation and written test, and the setting of scoring criteria for each evaluation element was insufficient. In terms of the content and timing of feedback, feedback was mainly provided based on achievement confirmation, but no case was found in which scaffolding was provided at an appropriate time for insufficient parts in the learning process. In terms of the learner's growth management, the competencies cultivated through science classes were included in the detailed subject specialties of the school record. However, little was shown in the report on how to systematically manage the process of developing learners' competencies and reflect the evaluation results to teachers' class improvement.

This means that development of industrial society has brought pains not only to workers themselves but also to their family due to various disasters, while it changed us to be affluent and improved the quality of life. The purpose of this study is to make the preliminary data for understanding the efficiency of the educations through examination of the existing state in performance about education programs for supervisors, which are in-house educations performed by the company itself and consignment educations performed by outside professional education institutions, in industrial safety and health education programs for prevention of industrial disasters and analysis on survey research of supervisors working at Anyang area to find out whether or not the in-house education and consignment education in education programs for supervisors have statistically significant differences in their ages, classification by industry, the completion number of educations, the number of regular employees regarding duties of supervisor determined by the Industrial Safety and Health Act. As the result of study, this study resulted in that consignment education performed by professional education institutions would be more helpful for improvement of job competence than in-house education performed by company itself. This can be interpreted that consignment education performed by professional education institutions has reacted more flexibly to continuous revisions of the Industrial Safety and Health Act and also more faithful to demand survey by consumers not being tied down by the conventionality for continuous development and study of the curriculum than that of in-house education.

This study aimed to evaluate the courses of pediatric dentistry based on correlation analysis between scores of objective structured clinical examination (OSCE) and related subjects for 79 fourth-year students. The score of theory were related to preclinical (r = 0.449, p = 0.000) and clerkship (r = 0.437, p = 0.000) each, but the scores of clerkship were not related to OSCE. To make the students skillful for clerkship, more professor's firsthand teaching on treating patients and adequate numbers of clinical professors are required. Patients who come to the university dental hospital prefer to be treated by professors rather than students. In these circumstances, educational conditions should be arranged by ensuring the number of professors for teaching students to improve their clinical competence through direct instruction and feedback to students. In addition, pragmatic improvement plans, which allow continuous education and evaluation about basic techniques to be examined in the clinical practice course, should be compromised with the more concrete evaluation of the curriculum in order to evaluate theoretical knowledge and technical trainings to be well exercised and deepened in the practical clinical field.

Ferulic Acid (FA) is a metabolite of phenylalanine and tyrosine, a phenolic compound commonly found in fruits and vegetables. Several studies have shown that FA has various functions such as antioxidant effect, prevention of cell damage from irradiation, protection from cell damage caused by oxygen deficiency, anti-inflammatory action, anti-aging action, liver protective effect and anti-cancer action. In this study, we investigated the maturation rate, intracellular glutathione (GSH) and reactive oxygen species (ROS) of porcine oocytes by adding FA to the in vitro maturation (IVM) medium and examined subsequent embryonic developmental competence at 5% oxygen through parthenogenesis. There is no significant difference between the control group ($0{\mu}M$) and treatment groups ($5{\mu}M$, $10{\mu}M$, $20{\mu}M$) on maturation rates. Intracellular GSH levels in oocyte treated with $5{\mu}M$ of FA significantly increased (P < 0.05), and $20{\mu}M$ of FA revealed significant decrease (P < 0.05) in intracellular ROS levels compared with the control group. Oocytes treated with FA exhibited significantly higher cleavage rates (79.01% vs 89.19%, 92.20%, 90.89%, respectively) than the control group. Oocytes treated with $10{\mu}M$ showed significantly higher blastocyst formation rates (28.3% vs 40.3%, respectively) after PA than the control group. Total cell numbers in blastocyst of $10{\mu}M$ FA displayed significantly higher (39.4 vs 51.9, respectively) than the control group. In conclusion, these results suggested that treatment with FA during IVM improved the developmental potential of porcine embryos by increasing intracellular GSH synthesis and reducing ROS levels. Also, there was an improvement of cleavage rate, blastocyst formation and total cell numbers in blastocysts. It might be associated with Keap1-Nrf2 pathway as an antioxidant regulate pathway that plays a crucial role in determining the sensitivity of cells to oxidative damages by regulating the basal and inducible expression of enzymes which is related to detoxification and anti-oxidative effects, stress response enzymes and/or proteins and ABC transporters.

The informatics computer teacher appointment examination is the only national test to measure the competence of educators in teaching students relevant informatics content. The purpose of this study is to provide suggestions and directions for improvement of the informatics computer teacher appointment exam. To this end, we collected appointment exam questions from 2002, when the informatics computer teacher appointment exam first started, to 2017. Based on evaluation areas and evaluation content factors of the indication subject of informatics computer, we built the analysis framework and criteria used in this study. The analysis took into account the revision of basic required courses and changes in the types of exam questions. We analyzed the percentage of points allotted to the subject matter compared to the total number of points, and also the trends of exam questions by school year. The results of the analysis are as follows: first, improvements should be made to avoid concentration in certain areas of the basic required courses of the informatics computer subject. Second, the discrepancy between the exam and the curriculum of basic required courses must be addressed to properly teach and evaluate preliminary teachers. It is significant that this study serves as a stepping stone in supplying highly competent teachers to the field through improving the informatics computer teacher appointment examination.
