The purpose of this study was to investigate the current status of postpartum depression intervention program performed in Korea and to evaluate its effectiveness. Of the Korean academic journals reported until November 2018, 13 experimental studies were selected and used for final analysis. The average age of the subjects was 26.9 to 34.4 years, and subjects were puerperal women or couples. The sample size was 6~39 (mean: 20.4) in the experimental group, 5~40 in the control group (mean: 20.0), and the intervention program consisted of 0.5~12 weeks/2~14 sessions/10~120 minutes per session. The design of all the studies was a non-equivalent control group pre-post test design. The main dependent variables, postpartum depression, fatigue, and maternal role self-confidence, were all found to have a statistically significant median level of effect size in the meta-analysis. This study confirms the composition and effects of various experimental studies used to mediate postpartum depression in Korea. This could be used as specific evidence-based data to form an optimal postpartum intervention program.

For a long time, mathematics education institutions such as NCTM(National Council of Teachers of Mathematics) have emphasized the essential role of writing, and recent surveys by the Ministry of Education report a decline in foundational academic skills in the post-COVID19 period. The purpose of this study is to redefine the significance of mathematics writing in mathematics education, focusing on competencies highlighted in the field, particularly in the areas of problem-solving, communication, and reasoning. The research findings indicate that writing in problem-solving enhances cognitive organization, fostering the ability to grasp concepts and methods. Writing in communication builds confidence through the meta-cognitive process, and writing in inference allows self-awareness of step-by-step identification of areas lacking understanding. Particularly in the future society where artificial intelligence(AI) is utilized, changes in the learning environment necessitate research for the establishment of authenticity judgment through writing and the cultivation of a proper writing culture.

The aesthetic appearance of the incisors is essential for a natural and healthy smile, and it is also an important factor for confidence in interpersonal relationships. If there is crowding or protrusion of the anterior teeth, root canal treatment and excessive tooth removal are often required to resolve it in a short period of time. However, it is difficult to achieve sustainable aesthetic results. In this case, orthodontic treatment will be necessary to preserve the remaining tooth structure as much as possible. Middle-aged and elderly patients are often aware of the need for orthodontic treatment, but they are hesitant to use the traditional orthodontic treatment method using brackets because of the social gaze. In this case, clear aligners can be a good option. So, in this article, a case in which aesthetic needs were resolved with clear aligners alone and another case in which satisfactory results were obtained through restorative treatment following clear aligners application are reported.

Despite the increasing number of international students in Korea, there is a lack of research on the health information-seeking behavior of international students. This study examined the health information search behavior of international students in Korea through a questionnaires and in-depth interviews adopting Critical Incident Technique. Most frequent health information needs that the participants experienced were related to Covid-19 and locating doctors/hospitals. The difficulties in seeking health information were language barriers, lack of knowledge of the Korean medical system, insufficient or overflowing information on the Internet. However, despite the language barrier, international students mainly used Korean sources (friends/family, websites, social media) for searching health information. In order to search health information on Korean websites, they used Google Translator or got help from bilingual friends/family members. The participants who have lived in Korea for a shorter period of time or who have lower Korean language proficiency tend to obtain health information through the community on social networks; whereas the longer the period of residence in Korea and the better the Korean language proficiency, the more likely to use websites. Only 28% of the participants gave positive answers to the question asking their confidence in finding the health information they needed. It is discussed how to help international students find accurate and credible health information.

The purpose of this study was to investigate the effects of using the play with multiplication activities based on Skemp's theory for mathematics achievements and attitudes toward mathematics of elementary school students. For this study, we rearranged Skemp's play activities according to our curriculum in the area of multiplication and applied them to the 2nd grade classes of an elementary school. The plays with multiplication activities were applied to the experimental group while traditional teaching method was used with the current mathematics textbook for the comparative group. We obtained the following conclusions: First, in terms of mathematics achievement, the experimental group who used the plays with multiplication activities based on Skemp's theory didn't show significant difference with the comparative group. Second, it proved that the plays with multiplication activities based on Skemp's theory was more effective for lower level of students than the higher level of students. Third, the plays with multiplication activities based on Skemp's theory have positive effects on improving students' attitudes toward mathematics. We need to use the plays with multiplication activities based on Skemp's theory in the classrooms and find problems with the applying the activities. In addition, we need to develop a more various activities based on Skemp's theory for a better teaching.

This study looked into Japan's recognition of Korea in early modern era with particular focuses on discourse on Korea and contents in textbooks in those days. In doing so, the topics of nationality, historical recognition, and social aspects in Korea were established and discourse on these topics in educational journals and the contents of textbooks and teaching manuals projected with such discourse were investigated. As for nationality, a strong propensity to negative recognition was clearly observed, represented by the words lazy, enervate, and uncivilized. They defined Korea's history of passive, other-directed nature and described such incompetent national management resulted in negative nationality. Their recognition of Korean history went further away, stating Korea was incapable of maintaining its independence and was a threat to peace of Japan and Asia, hence the forced merger by Japan. The criteria for Japan to assess Korean society were Western civilization and they defined Korean society as a pre-modern society with lower levels of civilization and culture. Discourse in Japan over Korea in early modern era were strongly influenced by Japan's pride as a modern state and its dominating ideology of imperialism and such discussions were spread among students through textbooks and teaching manuals.

According to the cognitive conflict process model, student anxiety factor is known to have both positive and negative effects on student response behaviors in a conflict situation for conceptual change learning. However, there is little research that reveals what type of anxiety, either constructive or destructive, is related when conducting step-by-step experiments to resolve cognitive conflicts. This study attempted to learn the characteristic of explanatory hypothesis according to anxiety type after conducting five step-by-step experiments related to action and reaction concept. Results found that students who belonged to the types of 'conviction in logical misconception', 'insisting on additional variables', and 'reasonable modification' suggested explanatory hypothesis close to physical nature. On the other hand, those who showed the other five types of anxiety ('compatible predictions', 'dependence on others', 'fusion of past experience', 'lack of confidence', and 'conflict with past experience') suggested temporary supported hypothesis or simple explanatory hypothesis according to student intuition and simple observation. These results indicate that students in the above-mentioned five categories need more external interactions with instructors based on the type of anxiety related to student behavior. In addition, the results present student characteristics which instructors should be more attentive to when using step-by-step experiments to resolve cognitive conflicts.

Recently an extensive study of the mathematicians who have overcome the visually impaired and contribute to the academic in math was published. In the case of Korea, we can find there are mathematicians who have overcome physical disabilities such as cerebral palsy and polio. However there is no example of blind person who majored mathematics to become a mathematic's teacher or professor and have entered any mathematics related professions. This let us to study the reasons that caused difficulties to visually impaired students majoring in mathematics. We also suggest ways that may help blind students to have access to mathematics intuitively. In this study, we propose a tactile mathematics textbooks and teaching manuals utilizing 3D printing which the visually impaired students can touch and feel. We can supply such materials to visually impaired youth, special education teachers and parents in Korea. As a result, visually impaired students will be able to access mathematics easily and can build their confidence in mathematics. We hope that some blind students with mathematical talent do not hesitate to major mathematics and choose career in mathematical professions.
