Recently, artificial intelligence has been widely used in various fields. Traditionally, students have studied in cramming methods rather than self-directed learning through schools and numerous extracurricular activities. In order to alleviate the problem of injection-type education, students can be expected to improve their self-directed learning skills by considering the level of students through the artificial intelligence English word app. In this paper, we will propose ways to utilize artificial intelligence for efficient learning.

To maximize educational effect with new educational methods in the 4th Industrial Revolution era, immersive education has become the core type of education and virtual reality (VR) is at the center of realistic content. VR education is increasing in school, but researches on VR production education are insufficient. Our study has proposed a school-level curriculum for students to create their own VR content. The output and the survey results were analyzed to find out the learner characteristics of elementary school students, middle school students, and pre-service teachers at each school level. As a result, there were some noticeable differences in concentration, content subject, and production time according to school level. Primary school students focused on their subjects, middle school students related to learning, and pre-service teachers put top priority on contents useful for primary education.

Purpose: Wasting and underweight are the 2 main indicators of children's undernutrition. We aimed to estimate the prevalence of undernutrition at the national level in Iran. Methods: We performed a search for original articles published in international and Iranian databases including MEDLINE, Web of Science, Google Scholar, Scopus, CINHAL (Cumulative Index to Nursing and Allied Health Literature), Scientific Information Database, Irandoc, Iranmedex, and Magiran during January 1989-August 2017. Seven keywords, in English and Persian, including malnutrition, protein energy malnutrition, growth disorders, underweight wasting, weight loss, children below 5 years old, and children, were used to search the databases. Results: Finally, 17 articles were included in the meta-analysis, based on which the prevalence of underweight and wasting in Iranian children were estimated to be 11% and 5%, respectively. The prevalence rates of underweight among children in the central, western, southern, and northern parts of Iran and at the national level were 24%, 5%, 20%, 17%, and 6%, respectively. The prevalence rates of wasting in the central, western, southern, and northern parts of Iran and at the national level were 9%, 4%, 11%, 5%, and 4%, respectively. Conclusion: Although the prevalence of underweight and wasting in Iran was low, some parts of the country showed high prevalence. The main reason behind this difference in the prevalence of malnutrition may be due to the level of development in different regions.

With advances in technology, many researchers have made an effort to find out educational methods with customized instruction. The purpose of the research is to investigate i) if flipped learning is beneficial for the students taking intermediate-level English grammar and writing class compared with the traditional class, ii) if the flipped learning class is advantageous for all the score level students in terms of student achievement and iii) if the students feel motivated with the flipped learning class. T-test was utilized to determine any differences between pretest and posttest in student achievement. The result in terms of the academic achievement revealed that the flipped classroom approach for the low score group was found to be the least effective among others. In the case of flipped learning teaching method, the instructor should develop contents according to the level of learners. The development of customized contents tailored to the level of learners will enhance learners' learning achievement.

Background: We aimed to provide basic data for improving the effectiveness of the invitational training and reflecting it in the program in the following year by identifying the satisfaction level of trainees who participated in the "Dr. LEE Jong-wook Fellowship Program" funded by the Korea Foundation for International Healthcare. Methods: A qualitative study was conducted using a questionnaire interview. In the first stage of analysis, only the interview contents related to the research topic were classified by the researcher for the conversations recorded at the interview site, and in the second stage of analysis, the interview contents classified in the first stage were classified into each of those mentioned in this study. Results: The longer the trainees participated in the program and the better the accessibility, the higher the satisfaction with the program. In addition, the level of achievement of the trainees' goals and the level of improvement in their competence affected their satisfaction, and their difficulty in language communication during the training period was identified as a factor affecting the trainees' satisfaction level. In addition, competency improvement and satisfaction were positively correlated (r=0.75, p=0.03). Conclusion: When organizing a rehabilitation workforce capacity training program, it is important to identify trainees' needs, ensure accessibility, organize courses effectively, enhance English proficiency, and expand practical lectures to increase trainees' knowledge and understanding of rehabilitation.
