The aim of this paper is to study certain subclass ${\tilde{S^q_{\Sigma}}}({\lambda},\,{\alpha},\,t,\,s,\,p,\,b)$ of analytic and bi-univalent functions which are defined by using symmetric q-derivative operator. We estimate the second and third coefficients of the Taylor-Maclaurin series expansions belonging to the subclass and upper bounds for Feketo-Szegö inequality. Furthermore, some relevant connections of certain special cases of the main results with those in several earlier works are also pointed out.

National curriculum for environmental education recommends various teaching-learning methods including survey and discussion of environmental problems, investigation of case studies, experiments, role play, and field-experience learning in addition to the traditional lecture-oriented teaching methods. The field experience learning in environmental education is considered to be a good method to develop environmentally sound attitude and to cultivate environmental sensitivity, but here has been very limited research concerning models for field-experience learning. The aim of this study is to develop a model of the field-experience learning program of environmental education utilizing environmental facilities. In this study a kind of such a basic model was developed and presented. The developed basic model of the field-experience learning was applied to the case utilizing landfill facilities. A specific application of the landfill program to the Bangcheon-ri landfill, in Daegu, was also presented with related teaching materials developed in this studies. And various aspects in the program was discussed.

The aim of this study was to analyze the research trends in articles published in the Korean Journal of Medical Education (KJME) and Korean Medical Education Review (KMER) using keyword network analysis. The analyses included 507 papers from 2010 to 2019 published in KJME and KMER. First, keyword frequency analysis showed that the research topics that appeared in both journals were "medical student," "curriculum," "clinical clerkship," and "undergraduate medical education." Second, centrality analysis of a network map of the keywords identified "curriculum" and "medical student" as highly important research topics in both journals. Third, a cluster analysis of 20 core keywords in KMER identified research clusters related to academic motivation, achievement, educational measurement, medical competence, and clinical practice (centered on "learning," while in KJME, clusters were related to educational method and program evaluation, medical competence, and clinical practice (centered on "teaching"). In conclusion, future medical education research needs to expand to encompass other research areas, such as educational methods, student evaluations, the educational environment, student counseling, and curriculum.

The aim of this paper is to find directions for improving creativity education in a research-oriented college of engineering. As a method, we interviewed 17 professors and 7 students from a research-oriented college of engineering in Seoul, South Korea and learned about their experiences related to creativity education. As a result, we were able to identify 6 topics on which the interviewees' opinions vary. We found that most professors we interviewed did not think creativity was important in their classrooms as they thought passing on engineering knowledge was more important in foundational engineering education, and creativity is hard to define. However, their evaluation method in class showed that they valued creativity, and were trying to teach creativity with little success. Also, while the professors thought they needed more communication with the students to improve creativity education, the students thought they needed more autonomy. In consideration of our findings, we proposed 4 directions for improving creativity education in a research-oriented college of engineering. First, shift perspective on the foundational education for engineering. Second, connect basic curriculum and extracurricular activities. Third, actively connect basic curriculum with the industry. Finally, provide appropriate facilities that enable different types of interactions between professors and students.

The aim of modern medicine is to prolong life by fighting death. Doctors have traditionally believed that this was an ethical good deed. The negative connotation surrounding death has led to the avoidance of terminally ill patients. But in a modern society where death is medicalized, doctors have to see dying patients every day and are in a state of guilt from implementing meaningless life-sustaining treatments. Therefore, medical schools should allow medical students to embrace a new perspective through death education. Yonsei University Medical College has implemented death education since 2017 as an optional class for first and second year medical students. Students watch videos related to death once a week for 6 weeks and submit their reflections by e-mail. The professor reads the students' reflections and gives them weekly feedback. Through this coursework, students realize that death is not a medical event, but rather a part of life and completion. The ultimate purpose of death education is to transform blind life-absolutist identity into narrative identity.

The aim of this study was to explore teachers' values about teaching mathematics in the classrooms which implemented Lesson Study and Open Approach as a teaching approach. The targeted group was 83 school teachers from 4 schools participating in a teacher professional development project. The data was gathered through teacher questionnaires, lesson observations and interviews. Data analysis is based on Bishop's (1988; 2003; 2007) and Komin's (1990) frameworks. The results from the implementation of Lesson Study and Open Approach in Thai classroom found the different of the roles and behaviors of teachers and students in classroom. The results revealed 3 kinds of values about teaching: Mathematical values, General educational values, Mathematics educational values and also found that most of the teachers valued problem solving as an innovative teaching approach as against traditional approaches they were familiar with.

The education of mathematics in generalized schooling should aim to concentrate on the cultivation of mathematical abilities necessary for social life. Mathemeatical abilities for social life run as follows: A. Utilitarian aspects 1. classification and numbers 2. traffic network and connection of segments of lines 3. expectation of getting the winning number in a lottery 4. interests in dealing in unharvested rice crop B. Aesthetic aspects 1. finding the optimum value and 2. successful candidates in accordance with election methods Every nation has its own peculiar customs and circumstances. Therefore, in order to achieve the expected results, the education of mathematics should develop what every nation has on its own and apply them to school education.

Even though the woollen-yarn-making process as a whole has received much attention from customers in recent years, but yet there exist many problems to improve quality, productivity, and working environment in a small-medium woollen-yarn manufacture. To achieve the aim for improvement of quality and productivity, we have performed a period of education and training for workers. And thus this paper reports a study carried out them in the company located in near Pusan. Also, this paper describes a study how has a small-medium company introduced the education for the workers by authors. Among the possible outcome of this study is that the company does encounter considerable difficulties in the education and training. But to improve the quality and productivity, we assert that the company has to overcome these courses. We all recognize that the employer has been prepared for education and training to improve the employees' working conditions for a long time.

In this paper, I analyzed the russian cultural content of the russian textbook according to curriculum changes. The aim of this study is to analyze the content of the russian textbooks on russian culture. Our education of russian language begins in high school as a second language. And russian education in high school entirely depend on the textbook. In these circumstances, Russian textbooks play a very important role in the Russian language learning. For a practical and efficient language learning, acquisition of cultural knowledge is very important. Because cultural content can be learning motivational factors. But the contents of a textbook is not satisfactory enough to teach russian culture. More efficient textbook must be developed to advance student's linguistic ability.
