This study examines the trend changes in keywords and topics of STEAM education from 2009 to 2020 to derive future development direction and education implications. Among the collected data, 42 cases of Ministry of Education's documents, 1,534 cases of articles, and 880 cases of abstract of researches were selected as research subjects. Keyword analysis, keyword network and topic modeling were performed for each stage of STEAM education policy through the Python program. As a result of the analysis, according to the STEAM education policy stage, there were differences in the frequency and network of keywords related to STEAM education by media. It was confirmed that there was a difference in interest in STEAM education policy as there were differences in keywords and topics that were mainly used importantly by media. Most of the topics of the Ministry of Education's documents were found to correspond to topics derived from articles. The implications for the development direction of STEAM education derived from the results of this study are as follows: first, STEAM education needs to consider ways to connect multiple topics, including the humanities. Second, since the media has a difference in interest in STEAM education policy, it is necessary to seek a cooperative development direction through understanding this. Third, the Ministry of Education's support for core competency reinforcement and convergence literacy for nurturing future talents, the goal of STEAM education, and the media's efforts to increase the public's understanding of STEAM education are required. Lastly, it is necessary to continuously analyze the themes that will appear in the evaluation process and change STEAM education policy.

Aim of this study was to investigate the influence of forest experience program on depression, anxiety, and self concept in adolescents living in urban area. A total of 47 adolescents living in Seoul, South Korea were recruited for the study and participated in a series of forest experience programs that the Korea National Park Service had developed. Before and after applying the program, their depression, anxiety, and self concept were evaluated using Children's Depression Inventory (CDI), Revised Child Manifest Anxiety Scale (RCMAS), and Offer Self Image Questionnaire-Revised (OSIQ). The outcome measures were analyzed using paired-t tests. CDI score was significantly reduced after the program (before:$12.41{\pm}8.34$, after:$8.65{\pm}9.48$). Excluding 16 participants whose scores of Lie Scale in the RCMAS were more than 8 on the analysis, the total RCMAS score showed significant reduction after the program (before:$14.87{\pm}7.30$, after:$10.81{\pm}7.81$). There was no significant difference in the total score of the total self-image scale in the OSIQ. However, the Self-confidence (SC) which was used as subscale of the OSIQ was significantly higher after the program (before:$29.94{\pm}3.71$, after:$38.11{\pm}6.45$), and the Idealism scale (I) in the OSIQ increased significantly after the program (before:$21.03{\pm}3.80$, after:$23.17{\pm}3.89$). On our analysis, the forest experience program showed considerable positive effects on depression and anxiety in adolescents. This result leads the postulation that the program might be helpful for adolescents to adapt to their surrounding experiences and to achieve improvement in interpersonal relationship.

The objective of this study is to supply the good quality of experts the radiation industries in Korea and develop the major subject matter needed in the radiation industries and the curriculum in order to execute it for the variation of fields of employment at the department of radiation in the junior college and the development of the percentage of employment. In addition, this study is to improve the level of radiation experts engaged in the industries in quality, and it is to improve the social recognition of radiation rather negative now because of the development of radiation industry. As for the core results of this research, it was to suggest the detailed choice method curriculum proper to the service fields of radiation industries, but it may be subject to change due to each college's property and the educational objectives. From the result of this research above, it may be summed up as follows. First, as for the detailed curriculum by the service field, this study was to organize two subject matters: 1. the subject matter proper to the field of using the radiation, and 2. the subject matters proper to the safety control field of radiation. Second, as for the detailed curriculum by the pattern of industries, this study was to organize the four subject matters: 1. the subject matter needed in the manufactures, 2. the subject matter needed in the nondestructive testing industries, 3. the subject matter needed in the sales agencies, and 4. the subject matter needed in the laboratories. This study was to suggest the operational model about the curriculum in order to execute these subject matters. It could be executed as two methods below. First, one method is to execute the major systems by the medical field and industrial field in the third course at the department of radiation in the junior college now. Second, the other method is to make them specialize the industrial radiation in the Advanced Course(one year course) after the graduation of junior college. To operate these curricula successively it needs to assume the deeper research and the development of materials about the subject matters related to the nuclear radiation industries hereafter. In addition, it needs to solve the security of finance like the manpower of professor, space for practice, and the educational appliances, etc. needed in the operation of subject matters. Finally, the effect and result from the development or revision of college curriculum did not come out in a short time. It will require considerable time until the undergraduates at the department in the junior college finish a set of curriculum newly developed, and graduate the university, and can get the results while they engage in their works in the industrial sites. Accordingly, all the interested parties have to anticipate the results of this research with the patience in long-standing point of view. Also, this researcher considers it as it is willing to give them the continuous interest and support.

This study aims to elucidate the historical origins of the long-term demand for the integration of "science subject classes" and "science-related events" within the context of science education for teachers. During the 1970s, science education in elementary schools faced a dual challenge marked by the tension between implementing the third curriculum, which emphasized fundamental science, and the "Pan-National Scientification Movement," which focused on technology education. The Ministry of Education was compelled to integrate the sudden demands of the Yushin regime into the ongoing third curriculum. As these demands emerged from dual policy directives, activities related to elementary science education were subsequently categorized into formal science subject classes and extracurricular science-related events. Although the movement did not directly alter the curriculum, it instigated modifications in personnel structure, activity spaces, and evaluation systems within schools. The introduction of the Pan-National Scientification Movement in elementary schools resulted in changes including the establishment of a new "science lead teacher system," the creation of a dedicated "science corner," and the implementation of a "science badge system." Although the movement was abruptly introduced, it ostensibly contributed to the advancement of the inquiry-oriented approach promoted by the third curriculum. Paradoxically, this advancement was facilitated by the integration of the consequences of the movement into schools' autonomous, extracurricular activities spearheaded by frontline education offices and schools. Although the movement represented a government-driven policy at a particular juncture in time, the manner in which science education practitioners responded to urgent governmental mandates, while preserving the integrity of the long-established third curriculum framework, involved dividing education activities into subject-specific classes and extracurricular science activities. Examining how science education practitioners in the 1970s proactively addressed these challenges offers valuable insights for the science education community in adapting to the current rapidly evolving educational landscape.

The purpose of this study is to examine the problems in the teaching practice of beginning science teachers who participated in the collaborative mentoring program to improve their teaching expertise. The participants were six beginning science teachers and six mentors at middle and high school levels. From each beginning science teacher and mentor teacher, journals, one-to-one mentoring records and transcripts, interviews and questionnaires, and transcripts conducted at the beginning, middle and the end of the mentoring program were collected. Seven aspects of the beginning science teachers' problems in their teaching practice were identified. The result showed that mentee teachers didn't set up specific learning objectives and they organized and presented lesson contents without considering students' proficiency level. Also, they found it hard to prepare for the lessons irrelevant to their major field of study and they tended to use convergent questions more than divergent questions. Mentee teachers tend to give teacher-centered rather than student-centered teaching. Beginning teachers' recognition of their problems in their teaching practice tends to lead changes in their teaching practice. Some of the problems that mentee teachers showed could be overcome if they recognized the problem through the collaborative mentoring program, but if not, it tends to remain throughout mentoring program.This study also highlighted the importance of reflection on beginning science teachers' practice.

The purpose of the study is to investigate the predisposing factors of posttraumatic stress disorder (PTSD) in fire fighters in Korea and to suggest the program development and solution to the critical incident stress management (CISM) in the future. PTSD is characterized by invasion, withdrawal, negative change of cognition and mood, and hypersensitivity. Trauma memory includes explicit memory and implicit memory. The explicit memory is conscious, cognitive, and descriptive and is controlled by hippocampus. The data of explicit memory have inhibitive and narrative language structure. The implicit memory is inconscious, emotional, and remembered by the body. The implicit memory is controlled by amygdala and has inexpressive language structure. The deletion of implicit memory is the key point to trauma treatment. Critical incident stress management (CISM) is the approach for the solution of PTSD. In conclusion, the essential goal of CISM is the psychological cessation of PTSD. This study tried to suggest the education program development of PTSD.

The aim of this study is to examine changes in swallowing function and quality of life with therapeutic singing-based music therapy for patients with dysphagia. The music therapy program was based on the previous study (Kim, 2010), and designed to improve breathing, phonation, and swallowing functions focusing on laryngeal elevation. Three patients with dysphagia participated in this study and each participant received a total of 11 or 12 individual music therapy sessions and each session was conducted for 30 minutes. In this study, three kinds of measurements were used. First, the measures of maximum phonation time (MPT), fundamental frequency, average intensity, jitter, shimmer, noise to harmonics ratio (NHR) by Praat test, second, laryngeal-diadochokinesis (L-DDK) to investigate laryngeal elevation, and last, the Swallowing-Quality of Life (SWAL-QOL) was measured. These cases have shown improved breathing, phonation, swallowing function, and the scores of SWAL-QOL in all of the patients. It suggests that this music therapy intervention was effective on laryngeal elevation, and the music intervention with therapeutic singing can be effectively implemented in further research for patients with dysphagia.
