Underwater images often suffer from color distortion, blurring and low contrast, which is caused by the propagation of light in the underwater environment being affected by the two processes: absorption and scattering. To cope with the poor quality of underwater images, this paper proposes a multiscale fusion underwater image enhancement method based on channel attention mechanism and local binary pattern (LBP). The network consists of three modules: feature aggregation, image reconstruction and LBP enhancement. The feature aggregation module aggregates feature information at different scales of the image, and the image reconstruction module restores the output features to high-quality underwater images. The network also introduces channel attention mechanism to make the network pay more attention to the channels containing important information. The detail information is protected by real-time superposition with feature information. Experimental results demonstrate that the method in this paper produces results with correct colors and complete details, and outperforms existing methods in quantitative metrics.

The purpose of this study is to develop an educational program to enhance convergence competence of undergraduate engineering students and analyze its educational effects. Prior to the development of the convergence education program for engineering students, 13 experts in engineering education field surveyed the needs of the convergence education program and 829 students from four engineering colleges in the Seoul metropolitan area, Chungcheong area and Honam area were assessed for the level of convergence competency. The educational program was developed based on the needs analysis and the program consisted of four major themes: convergence lecture, convergence competence, convergence practice, and convergence vision. The validity of the program was confirmed through the two expert validation tests. A total of 40 students participated in the selection of 10 students from each of the four universities. As a result of pre-post comparison of students' convergence competencies, the average of all competencies increased, and it was found that there were statistically significant differences in convergence mindset, differentiation mind, commitment, communication, and social value competence. Implications for the improvement of education programs and convergence education were suggested.

학령인구의 급격한 감소는 대학마다 정원을 확보하는 것과 함께 입학한 학생들의 중도탈락을 막아야 하는 과제를 동시에 요구하고 있다. 현실적으로 모든 대학에서는 중도탈락자가 발생하고 있으며, 특히 4년제 대학에 비해 전문대학이 더 높은 중도탈락률을 보이고 있다. 중도탈락과 관련된 기존 연구들은 그 원인을 분석하는 내용들이 많았던 반면, 중도탈락을 줄이려는 프로그램의 개발과 관련된 연구는 부족한 면이 있다. I-대학에서는 학업준비가 부족하고 소외된 부류의 학생들에게 초점을 맞춰 프로그램을 개발하였다. 또한, 개발된 프로그램을 운영한 결과 소외 학생들의 학업성적이 향상되었다. 하지만, 지속가능한 프로그램이 되기 위해서는 학교에서 진행하는 다른 목적의 프로그램과도 연계성이 필요할 것으로 판단된다.

Background: Education on environmental health in Korea was begun with establishment of the Graduate School of Public Health at Seoul National University 1959. The sanitary movement started in Europe and the Americas in the 19th century and was introduced to Korea in the 1960s under the name of sanitary engineering. The field enlarged along with title changes. Objectives: The purpose of this study was to investigate the previous and present status of the environmental and public health fields in Korea. Methods: This study utilized documents published by the South Korean Ministry of Education and Korean Education Development Institute (KEDI) from 2015 to 2020, the homepages of universities with their history and regulations, and other related published documents. Results: Public health was fundamentally enlarged as an expert field in Korea with the establishment of the Graduate School of Public Health at Seoul National University in 1959. There are 102 departments relevant to the environmental field at two-year colleges, 220 at universities, and 175 at graduate schools. There are 89 departments relevant to the public health field at colleges, 96 at universities, and 160 at graduate schools as of 2020. The term "environment" in the title of a department is used as much as 80~93.1%, but "public health" in titles is used in 47.7~61.5%. Fifty percent of graduate schools of public health award specialty degrees other than master of public health. Conclusions: Although environment and public health fields have been expanded in universities in Korea, various specialty fields were included in university and graduate school. It is important to consider the coping plan with the trend.
