The purpose of this study is to investigate the current status of STEAM (Science, Technology, Engineering, Arts, and Mathematics) education in schools by asking a variety of questions including "why and how often they implement STEAM education." This study conducted an online survey on 11,526 elementary, middle, and high schools in South Korea, with the response rate being 56.8% (N = 6,473). To highlight key findings, first, our descriptive analyses suggested that if those that did not respond to the survey were assumed not to have implemented STEAM education, approximately 27.1% (N = 3,127) of all schools in South Korea were believed to have implemented STEAM at best. The highest rate of implementation of STEAM education was found in elementary schools (30.8%), followed by middle (27.4%) and high (17.5%) schools. Second, in contrast with the result for the rate of implementation of STEAM education, high schools showed the highest level of satisfaction. Third, the most important reason for implementing STEAM education within a school was found to be teachers' voluntary efforts or intrinsic motives, followed by support from the provincial office of education. Fourth, the most important reason for not implementing STEAM education was found to be the lack of consensus among teachers. Together, findings highlight the importance of the role of teachers in implementing STEAM education. Offered are policy implications for the better implementation of STEAM education.

This study investigates the credibility judgements of information by tweens using digital media and information. Particularly, the study focused on tweens' perception of internet research and information use and on their credibility judgement of source and message, internet service providers, and on consulting with others for their credibility judgement. The survey methodology was used to collect data from grade 5 and 6 students in two elementary schools whose parents are likely in middle and upper class. 336 valid questionnaires were collected among 400. Descriptive statistics, factor analysis, and t-test were used to analyze the data collected using SPSS 25. Findings suggested that tweens understood the importance of using smart media and computers, that they used Youtube, Naver, Kakao talk, Naver JisikIN much in sequence, and that they believed the Internet research was easy and fun. Using exploratory factor analysis, the survey questions for credibility judgement were classified into three factors: Internet service providers, sources and information, and consulting with others. Tweens used sources and information credibility, consulting with others credibility, Internet service providers credibility in sequence. However, it was interesting to find that there were greater deviation in answers on knowing how to find out the cognitive authority of the authors and on the importance of using current information. This study suggests the critical need for tweens' credibility judgement research for promoting critical thinking skills as well as for proactive educational practices in schools and libraries on information literacy.

The purpose of this study is to survey the status of the 7th elective-centered curriculum and find problems in operating the system. 485 students in the tenth and eleventh grade were randomly selected as subjects. The results are as follows. (1) Among the students, 29% of them selected their science subject without considering their future jobs, 48% did it without enough overview of the system, and 25% did without clearly understanding the details the choice centered curriculum. (2) Among the students who participated in the survey, 65% of them showed positive responses concerning the needs of individual choice centered curriculum and 96% said it increased their participation in class. However, only 39% believed that operating this type of curriculum is realistically possible. (3) 89% of students selected their science subjects accordingly with the college preparatory courses and 14% selected based on their hopes. (4) The percentage of science subjects chosen are 40% for chemistry, 25% for biology, 22% for Physics, and 13% for earth science, but 74% of students wanted to change their choices. These results showed that students recognized the object of the 7th curriculum, but selected science subjects as a means of getting into college entrances, rather than carefully considering their future and aptitude.

TMJ Osteoarthritis is a degenerative disease caused by overload on joint tissue, and often accompany with local tenderness on the joint, crepitus by mandibular movement, restriction of mandibular movement, and anterior openbite. In general, panoramic radiography, TMJ panoramic radiography, and transcranial radiography are conducted to diagnose osteoarthritis after clinical examination, however, these radiographic evaluations are limited in detecting minute bony changes of early pathologic lesion. The aim of this pilot study was to evaluate the limitation and usefulness of several TMJ imaging techniques, so we compare the findings from clinical examination, plain film radiographs, tomograph, and bone scan from 81 patients with temporomandibular joint disorder. The proportion of patients showing same findings in plain film radiographs, TMJ tomograph, and bone scan was high, however, it is desirable that clinician should conduct phased imaging examinations according to the clinical findings due to the possibilities of false negative findings in diagnosis of osteoarthritis.

Apert syndrome is a kind of congenital-acrocephalosyndactyly syndrome which was first reported by Apert in 1906 and characterized by its acrocephaly and syndactyly. Clinical characteristic features are cone-shaped skull morphology due to early fusion of coronal suture, fusion of fingers of hands and toes of feet. It is an autosomal dominant-heritable syndrome. Due to hypo-development of midface region, Apert syndrome patients have a tendency to have ocular proptosis, hypertelorism, maxillary deficiency. High palate and soft palate cleft are common findings in these patients. In general, mandibular growth pattern is normal, but relative maxillary deficiency exaggerates mandibular forward position, so relative mandibular prognathism is inevitable. Narrow maxillary and mandibular dental arch worsen teeth alignment and crowding. Skeletal malocclusion and open bite are also common. This is a case report of a Korean 3 year 1 month male Apert syndrome child referred by department of plastic surgeon for the possibility of orthodontic treatment. General features of Apert syndrome, patient's medical history, radiographic evaluation, clinical examination, orthodontic and surgical treatment planning are discussed in this report.

The purpose of the this study is to analyze consulting demands in vocational education and training (VET) high schools participating the apprenticeship system in Korea. The results of the study are as follows. Firstly, there are 9 sections of consulting that teachers in charge of apprenticeship program in VET high schools demanded. Especially, the demands for the consulting that related with 'student evaluation', 'apprenticeship program development and organization planning of schools' curriculum', 'selection and management of enterprises', 'organization of apprentices classes and student management', 'teaching & learning activities and textbook development' were relatively high. Secondly, there were differences in demands of consulting by VET high schools' current management status. By the type of organization, demands for consulting of both 'training center in main school' of organization and 'training center in common' of organization were higher than 'independent school' of organization generally. By the type of apprenticeship program hours, demands for consulting of both 'above 1400 hours' and '1200 ~ 1400 hours' were higher than 'less than 1200 hours' generally. By the type of OJT operation, demands for consulting of 'a type of OJT that is operated in long term(more than 2 weeks)' were higher than 'a type of OJT that is operated weekly' generally. As a result from above, there are some pre-requisites for the stable operations of VET high schools. 1) The apprenticeship program shall be developed not to interrupt school's regular curriculum. 2) For the smooth management between apprenticeship program and school curriculum, the academic calender has to be established so as the type of OJT operation. 3) The cooperation among the participating schools in part of the organization is unavoidable.
