The study aimed to examine the trends of research on vocational education at the secondary level. The study also intended to reveal changes of research interests among the four different Administrations since 1995. A total of 92 research articles on the journal of vocational education research was analyzed using the content analysis method and the network text analysis method. About 36% of all studies was done at the Lee Myounbak Administration, and 30% at the Kim DaeJoong administration, 20% at

본 연구는 2008년 마이스터고 도입 이래 지금까지 수행된 마이스터고 연구를 종합하여 연구동향을 탐색하고 향후 연구과제를 제시하는데 목적이 있다. 학술지와 학위논문으로 나누어 기성 연구자와 학문 후속세대의 연구관심을 비교하였다. 학술지 논문 33편, 학위논문 24편 등 총 57편이 분석되었다. 주제어의 빈도와 연결중심성을 탐색하는 네트워크 텍스트 분석과 분석 준거별 빈도를 살펴보는 내용분석을 실시하였다. 네트워크 텍스트 분석 결과, 마이스터고 연구는 학생과 교원 등 학교 구성원을 대상으로 한 연구가 다수였으며, 학술지 논문이 학위논문보다 연구분야가 다양하였다. 주제어의 연결중심성을 분석한 결과, 학교 구성원의 심리적, 정서적 요인에 대한 연구가 많음을 알 수 있었다. 연구주제는 학교 구성원(56.1%)에 대한 논문이 가장 많았고, 다음으로 교육과정(17.6%), 학교운영 및 조직(14.0%), 정책분석 및 평가(12.3%)에 관한 연구가 많았다. 연구방법은 양적 연구(59.6%)가

Background/Aims: We evaluated whether manometric subtype is associated with treatment outcome in patients with achalasia treated by peroral endoscopic myotomy (POEM). Methods: High-resolution manometry data and Eckardt scores were collected from 83 cases at two tertiary referral centers where POEM is performed. Manometric tracings were classified according to the three Chicago subtypes. Results: Among the 83 cases, 48 type I, 24 type II, and 11 type III achalasia cases were identified. No differ

Autostereoscopic 3D panels in augmented reality head-up displays use periodic optics to overlay pixel grids, creating a moiré effect. It is essential to predict this in advance to ensure display quality in virtual and augmented reality. The moiré effect in three-dimensional displays arises from the interference between the display panel’s pixel grid and periodic optical elements such as lenticular lenses or parallax barriers. While periodic gratings inherently exhibit infinitely many frequency c

Autostereoscopic 3D displays are used in augmented reality and virtual reality applications so that users can experience a 3D world without glasses by controlling the direction of light rays at each pixel. However, the use of 3D optics results in a reduction in image quality compared to 2D displays. It is therefore crucial to ascertain the 3D resolution for the accurate presentation of 3D content and to develop high-quality 3D displays using limited resources. This paper presents a methodology f

Since fires in uncontrolled environments pose serious risks to society and individuals, many researchers have been investigating technologies for early detection of fires that occur in everyday life. Recently, with the development of deep learning vision technology, research on fire detection models using neural network backbones such as Transformer and Convolution Natural Network has been actively conducted. Vision-based fire detection systems can solve many problems with physical sensor-based
