Myofibroma is a benign tumor composed of fibroblasts and myofibroblasts, occasionally occurring most commonly as a solitary lesion of soft tissue, skin, or bone in children younger than 3 years of age. Solitary lesion of myofibroma is exceedingly rare in adult jaws. This report describes a rare case of myofibroma in the mandible that occurred in a 41-year-old Korean woman.

This research is to investigate his creative perspective to Deahak through Seoktan Lee Shin-Ui's Daehakcharok. Lee Shin-Ui is a scholar and politician in the middle of Joseon Dynasty. His ancestral home is Jeonui. The honor name is Gyeongchik and pen name is Seoktan. The posthumous name is MunJeong. His Daehakcharok was written in the process of taking basic foundation as the politic leader. It was a record that he usually wrote down things realized after reading Deahakjanggu. Seoktan clearly classified the meaning of Jang (chapter) and Gu (phrase) as the structure of Deahakjanggu, and created new realm about the method of classified study. In the preface of Deahakjanggu, he emphasized that the core of Deahak is in Gyeong (敬, respect or honor), and clarified that Deahak deals with Sim (心, mind) and Seong (性, human nature). In the interpretation of Daehakdeajeon, he thought that the core of Samgangnyeong (三綱領, three doctrines or essential principles) depended on Myeong (明, realizing), Shin (新, taking re-newness), and Ji (止, achieving) as the meaning of 'realizing, taking re-newness, and achieving', and interpreted the context of Tao (道, the way), Myeong (明, realizing), and Deuk (德, virtue) in detail. In addition, he interpreted various concepts and meaning of Deahak with Myeongmyeongdeuk (明明德, realizing human nature) and Sinmin (新民, renewing people) as relationship with Ji(知, realization), Haeng(行, practice), Che(體, main structure), and Yong (用, dealing with), and developed Neo-Confucianism deeply. In case of the main interpretation of Deahakjanggu, he analytically reviewed 50 phrases one by one throughout 10 total chapters. In case of chapter five which includes Zhuzi's the theory of Gyeokmul (格物, approaching things or persons), he interpreted it in three parts and classified Gyeokmulchiji (格物致知, approaching things or persons and then realizing their nature) about researching deeply of principle and each thing, and Mulgyeokjiji (物格知至, approaching things or persons and then realizing them) about all things. He arranged in order of 'principle- researching-result' as well. In final, chapter ten showing the core of politic thought emphasized the way of Hyeolgu (?矩, considering others' situation through his/her own experience) intensively and informed that it is the best virtue for a governor.

In using lecture evaluation methods to improve the quality of education, most universities need to reflect the changes in the educational environment. The transformation of university education into a mixed learning environment blending face-to-face education and online education necessitates the development of appropriate lecture evaluation items. For this purpose, we analyzed the items and the factor analysis for the students of C university in Daejeon. The primary data were carried out with 47 measurement items in 10 domains, such as planning and preparation of lectures, which were found through previous research analysis. Secondary data were validated by using the items confirmed through analysis of preliminary test data. The study results showed that 20 items including six domains such as planning and preparation of lectures, learning materials, learning tasks, instruction media, online course test and grades were derived. These study results suggest that universities lectures should be evaluated to ensure improvement.

Recently, the number of mature students who apply nursing departments is increasing due to the increase in lifelong learning needs and the high employment rate of nursing jobs. This study aimed to investigate the effect of self-efficacy, satisfaction in major on college adjustment among mature nursing students. Data were collected from October to December, 2021 and a total of 148 mature student participated in this study. The result showed that the self-efficacy was 3.69±0.51, satisfaction in major was 4.07±0.50 and college adjustment was 3.42±0.50. As a result of analyzing factors, grade(β=.20, p=.001), self-efficacy(β=.43, p<.001) and satisfaction in major(β=.37, p<.001) were significant predictors of college adjustment, and the explanatory power was 54%. Mature nursing students are expected to increase in the future, and based on the results of this study, it is suggested that mature nursing students improve their college adjustment by providing intervention programs that can increase self-efficacy and satisfaction in major.

대전 관평천 유역의 도시계획에 의해 개발된 도시지역을 대상으로 우수 관거 최종 유출부에 설치한 모니터링시스템을 이용하여 복수의 강우사상에 대해 연속으로 유출량 자료를 획득하였다. 본 연구는 연속적으로 획득한 유출량 자료를 바탕으로 SWMM(storm water management model)을 보정하고 최적의 수문학적 매개변수를 산정하는데 있다. SWMM의 수문학적 매개변수는 기본 침투식인 Curve Number, Horton 및 Green-Ampt를 바탕으로 각각의 경우에 맞는 유역의 조도계수 및 저류 깊이를 산정하였다. 현재 도시 개발에 따른 유출변화를 모의하는데 있어 국외에서 연구된 매개변수를 적용하고 있다. 번 연구에서 구한 매개변수는 향후 도시개발에 따른 유출 변화를 SWMM을 이용하여 분석하기 위한 기초자료를 활용 할 수 있을 것으로 판단된다.

The melting phenomena of horizontal cylindrical ice-bar immersed in water and air concentrically in the cylinder are experimentally investigated for the temperature range from $3.5^{\circ}C\;to\;2.5^{\circ}C$. The shapes of the melting ice-bar are recorded photographically by the shadowgraph method. The shadowgraphs of the melting ice-bar show that water adjacent to the bar flows upward for the temperature range from $3.5^{\circ}C\;to\;5.8^{\circ}C$ while above $5.8^|\circ}C$ the flow is downward direction. The local and average Nusselt numbers are obtoined with the recorded shadowgraphs and comparator. Melting shapes of the ice-bar in the air show the vortex motion in the bottom portion of the bar, whereas no vortex motion appears in the bottom portion when the bar is melted in the water.

We experimented on cutting characteristics-cutting force, behavior of cutting temperature, surface roughness. chip thickness under low temperature, which generated by liquid nitrogen(77K). The work-pieces were freezed to-195 .deg. C and liquid nitrogen was also sprinkled on cutting area in order to decrease an experimental error of machining in low temperature. The workpiece was became to -195 .deg. C in5 minutes. In cooled condition surface roughness of workpiece was better than normal condition. In addition, we investigated the possibility that surface roughness of workpiece and cutting force can be predicted analyzing cutting conditions by the trained neural network.

This paper examines the characteristics of shared universities in Korea and seeks future development directions from the analysis of its operation. This study overviews the current status of students and the characteristics of each major in the DSC Shared University. This provides the future improvement direction and analyzes the survey of attending students. The results shows the most DSC students are engineering students, and they are taking classes centering on the major courses opened by their school. Future direction of shared universities include the recruitment of students from various backgrounds, expansions of enrollment in other schools' curriculum.
