Earth Science is the study of Earth, where diverse organisms live, and it mainly focuses on the healthy, wealthy, and comfortable environment for our descendants. UNESCO and IUGS recently established the International Working Group on Medical Geology (1996), IGCP 454 Medical Geology (2000-2004), and International Medical Geology Association (IMGA, 2006) with the primary concerns of increasing awareness of Medical Geology among scientists, medical specialists, and the general public. Medical Geology and IMGA have been very successful in informing(educating) about the relationship between geological factors and health problems in humans and animals in the world through numerous international meetings, seminars, workshops, symposiums, and publications. Since there is a close correlation between Earth Science and Medical/ Dental Sciences as shown in the Medical Geology and IMGA, Earth Science, as with other areas in science, (i.e., Biology, Chemistry and Physics) should be included in the Medical Education Eligibility Test (MEET) and Dental Education Eligibility Test (DEET) for the Medical and Dental Graduate School. In this brief note, services and activities of UNESCO IGCP 454 Medical Geology and IMGA are introduced, sothat the inclusion of Earth Science as a subject requirement in the MEET and DEET can be considered. Such outcome will balance the development of Science Education in Korea.

Malocclusion occurs more frequently in Special Health Care Needed (SHCN) patients than those in general. As caregiver's needs for orthodontic treatment tend to increase, the dentist should know how to decide the extent of treatment. This case report is about orthodontic treatment for two SHCN patients; one patient with cerebral palsy, and another patient with autism. A 10-year-old patient with cerebral palsy showed protrusion and rotation of maxillary anterior teeth. To resolve his chief complaints and make better oral hygiene, he underwent orthodontic treatment using micro tube appliances for 6 months. Another 11-year-old patient with autism had anterior crossbite and showed space deficiency of #13 and chronic gingivitis because of poor oral hygiene. She underwent orthodontic treatment with maxillary skeletal expander, facemask and AP expansion appliance. After 18 months we found positive overjet and ended the treatment. When giving SHCNs orthodontic treatment, the extent of treatment can be chosen according to the patient's cooperative ability and the traits of disabilities. Before initiating orthodontic treatment, the caregivers should be aware of their limitations of the treatment. Since oral hygiene is crucial factor in every dental treatment, education of oral hygiene process for the caregivers and SHCN patient must be done before the orthodontic treatment.

The diet composition of skinnycheek lanternfish, Benthosema pterotum were collected by bottom trawl net in the South Sea of Korea during 2021 (February, May, August, and November) and 2022 (February, April, August, and November). The size of the specimens ranged from 16 to 73 mm in total length. B. pterotum were mesopelagic carnivores that mainly consumed euphausiids and copepods. Its diets included small quantities of amphipods, shrimps, mysids, etc. We calculated the trophic level as 3.16 for B. pterotum. The individuals of small size class (<40 mm) fed mainly on copepods. In the next size classes (40~45 mm, 45~50 mm, 50~55 mm), copepods' proportion decreased and euphausiids increased. In the largest class (55~60 mm and ≥60 mm), the proportion of euphausiids' decreased, and shrimps increased. As the body size of B. pterotum increased the mean weight of prey per stomach (mW/ST) tended to significantly increase (One-way ANOVA, P<0.05).

A 20-year-old male patient with Down syndrome presented with rampant caries and chronic periodontitis on full-mouth. Patient have many oral diseases despite of no abnormalities of medical history, no involuntary tremor, no excessive masticatory pressure, and no limitation of exercise. Also he had no experiences of oral health education of prostheses and oral health management. Therefore, A number of fixed prostheses and denture treatments were performed to caregiver and patient with education for oral hygiene and management. After delivery final prostheses, they had repeated follow-up for checking management.

Flipped learning is a new learning technique which can maximize the learning effect by mixing two or more different learning environments including online & offline, and recently introduced system: 'Google classroom' is the optimized internet platform for flipped learning. This study tried to apply flipped learning to regular course 2nd grade dental students(n=70) and evaluated the satisfaction of students. The subjects of periodontology and operative dentistry were chosen to evaluate flipped learning model for regular course 2nd grade dental students(n=70). Each class consisted of six classes, and three times of them were performed in conventional classes and the other three times were in flipped learning method by using Google classroom. Evaluation of satisfaction progressed at the end of class. In this study, application of flipped learning in the dental college classes showed high efficiency in terms of degree of understanding, self-directed learning and motivation. Collectively, it was shown that flipped learning using Google classroom can be a reliable platform in dental classes.

The current trends in engineering education have been examined in order to address the situation of educating engineering workforce. It was found that the decline in the supply of manpower in engineering education had not been a serious problem since 2003. However, a large number of students who graduated engineering colleges intended to enter medical schools. Engineering colleges may consider developing high school exposure programs making students to explore engineering. Also policies are required for engineering program to be competitive for attracting and retaining strong workforce into an engineering career.

Mathematics(group theory, in particular) makes it partially possible to present and create music and patterns. This means that patterns can be presented by music through mathematics. In this work, we first produce musical piece for each type of frieze patterns. Based on the musical pieces, we compose a music presenting the combined pattern of all frieze types. We finally produce a video for hearing design through music. Through a QR-code, anyone can access the product of this work. The results of this research might be examples for integration of mathematics and arts and for utilizing smart circumstances.

The purpose of this study was to analyze the face validity of the revised EPTA (English Proficiency Test for Aviation) to see if the tests actually contribute to the enhancement of aviation safety and achieve the purpose of the assessment. In order to reach the above objectives, 103 pilot test takers were surveyed, and nine in-depth interviewees were selected and interviewed. In addition, detailed research results were derived by dividing the participants into the pilot's flight experience (31 captain pilots, 42 first officer pilots, and 30 general commercial pilots). As a result, pilot participants were generally aware that EPTA was more reasonable because the revised EPTA properly implemented the aviation situation and gave participants motivation to learn aviation English. It was also seen that first officer pilots had a higher face validity of EPTA than captain and general commercial pilots. The reason was that first officer pilots considered air traffic control job was more important than other pilots did.

Objectives: In this study, we strived to determine the possibility of socioeconomic welfare in oral healthcare by analyzing the National Health Insurance (NHI) coverage rate. To date, efforts to realize the "social economy" of healthcare are active. While oral disease is common and chronic among Koreans, the rate of NHI coverage of dental clinics is substantially lower than that of the medical clinics. Methods: We defined the NHI coverage of dental clinics as a proxy for "social skills" to improve oral health problems. The data were collected through a comparative analysis of the NHI coverage of dental clinics and that of non-dental clinics, in health welfare social cooperatives. Results: The NHI coverage rate of the dental clinics in health welfare social cooperatives ranged from 0.97 to 2.62 times that of the non-dental clinics in health welfare social cooperatives. Conclusions: In conclusion, responsible management is recommended for making health welfare social cooperatives meaningful as a social economy.
