This paper investigated how three representative domestic and international engineering education journals explored societal supports contributing to retention and persistence in engineering, especially among women. An integrative literature review of engineering education journals was carried out to identify the flow of research and practice of engineering education for females. The findings indicate that retention and persistence of women in engineering is closely relevant to issues of diversity management, collaboration competency, and self-leadership.

The Asian Conference on Engineering Education has organized and is held in Busan. This paper tells the steps for the process of planning of this conference. Firstly, the Innovation Center for Engineering Education in Korea Maritime University and the Center for Innovation and Creativity Development in The University of Tokushima signed the mutual interchange agreement on engineering education in 2005. The interrelation of both centers has made a continuous relation by mutual visiting of teachers and students. The first symposium on engineering education between the two universities was held in 2006. Three symposia were succeeded until now. By the way, the Japanese five-university coalition of engineering education was composed in 2004. This five-university coalition annually held the symposium on engineering education. Two teachers and two students of each university participated in the symposium and introduced their activities. Annual symposium was held every year from 2004 to 2008. Based on these two kinds of symposium, we have planned to enlarge the relationship by including partner universities in both countries. The capstone design coalition on engineering education between the Center for Innovation and Creativity Development in the University of Tokushima and the innovation center for engineering education in Korea Maritime University are introduced. The interrelation of both centers has held by mutual visiting of teachers and students during four years. The capstone design activities of Korea Maritime University and the students' creative design projects of the University of Tokushima were introduced each other. This coalition is planned that it needs to be enlarged by including partner universities in Asian countries.

We hypothesized that the unsaturated fatty acid palmitoleic acid (POA) could promote the expression of adipogenic/lipogenic genes in bovine skeletal muscle satellite cells (BSCs). The BSCs were cultured in a growth medium containing 10% fetal bovine serum. When the cells reached 80%-90% confluence, we used the differentiation medium with 5% horse serum for differentiation for 96 h. The differentiation medium contained 50 µM, 100 µM and 200 µM POA. Control BSC were cultured only in differentiation media. Compared with the control BSC, the POA BSC significantly up-regulated the expression of paired box 3 (Pax3) and paired box 7 (Pax7) and down-regulated myogenin gene expression (p < 0.01), which indicates a depression in muscle fiber development. However, all POA treatments up-regulated the expression of the adipocyte transcription factors peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer-binding protein alpha and beta (C/EBP α and C/EBP β), and other genes (p < 0.01) and increased the expression of PAT-family proteins and the concentration of adiponectin in the media. These results indicate that POA can convert part of BSCs into adipocytes.

A survey was conducted and analyzed for strengthening the employment competitiveness of engineering students. Questionnaires were conducted to students and graduates majoring in mechanical, civil engineering and computer science as well as to small and medium sized industries. It includes the level of satisfaction and requirement to recognize the situation of the students in metropolitan Seoul area. Survey results indicate that for undergraduates and graduates, knowledge of their own majors is most important. However, for industry, the most important factor is the ability of analysis and application, and their personalities. With the results of this survey, it is expected that these discrepancies between industries and students are reduced and the competitiveness of students is strengthened.

Utsunomiya University started a 3-year project to develop an education program for postgraduate students to cultivate leadership spirits. The program is centered on a PBL in which each group of students is required to find an engineering or social problem themselves and start a project to solve the problem. Projects vary widely, from a straight product development to a summer program for children or local area development. Student groups are advised by senior engineers from industries. They give advice as to how a project should be managed and run, but will not give instructions. The PBL is compulsory for all students in the engineering master course students. The new education program also includes a series of lectures by engineers to show engineers' job, activities, and career in the industry. Internship programs are also provided, in which students will be given opportunities to actively apply their knowledge and skills to real engineering tasks offered by the industry. The students are expected to gain something more than just experiences.

The purpose of this study is to objectively grasp the effect of the engineering education innovation support project among the national engineering-related financial support projects by dividing the groups according to the participation of support projects from 2018 to 2020 and dividing the university performance. As a result of the research the engineering education innovation support project has been consistently producing excellent results of field-based engineering education such as field-oriented industrial-educational collaboration capstone design, technology commercialization, and development and operation of corporate-linked education. It was found that the results showed that the dropout rate of college were lowered. In the future, it needs to be prepared as a place for new and free trials, innovations, and opportunities so that the engineering education innovation support projects can become the mother of other business groups.

Plutonium-238 has always been considered as the one of the promising radioisotopes for space nuclear power supply, which has long half-life, low radiation protection level, high power density, and stable fuel form at high temperatures. The industrial-scale production of ²³⁸Pu mainly depends on irradiating solid ²³⁷NpO₂ target in high flux reactors, however the production process faces problems such as large fission loss and high requirements for product quality control. In this paper, a conceptual design study of producing ²³⁸Pu in a multi-purpose high flux reactor was evaluated and analyzed, which includes a sensitivity analysis on ²³⁸Pu production and a further study on the irradiation scheme. It demonstrated that the target structure and its location in the reactor, as well as the operation scheme has an impact on ²³⁸Pu amount and product quality. Furthermore, the production efficiency could be improved by optimizing target material concentration, target locations in the core and reflector. This work provides technical support for irradiation production of ²³⁸Pu in high flux reactors.

Transuranic nuclides (such as ²³⁸Pu, ²⁵²Cf, ²⁴⁹Bk, etc.) have a wide range of application in industry, medicine, agriculture, and other fields. However, due to the complex conversion chain and remarkable fission losses in the process of transuranic nuclides production, the generation amounts are extremely low. High flux reactor with high neutron flux and flexible irradiation channels, is regarded as the promising candidate for producing transuranic nuclides. It is of great significance to increase the conversion ratio of transuranic nuclides, resulting in higher efficiency and better economy. In this paper, we perform an optimization design evaluation of producing transuranic nuclides in high flux reactor, which includes optimization design of irradiation target and influence study of reactor core loading. It is demonstrated that the production rate increases with appropriately determined target material and target structure. The target loading scheme in the irradiation channel also has a significant influence on the production of transuranic nuclides.

There's been few research to study the effects of CAC(Computing Accreditation Committee) evaluation, since start of CAC accreditation 10 years ago. The purpose of this paper is to find what computer engineering graduates perceive the effects of CAC accreditation and to suggest how CAC accreditation process can be improved. The research findings through survey are followings; First, computer engineering graduates' undergraduate education satisfaction is not high enough(3.28). Second, the computer engineering graduates don't recognize CAC accreditation necessary. Third, graduates who work in company chose design courses as the most helpful, while graduates who study in graduate school pursuing further career in master or doctor program chose major subjects. Lastly, graduates from accredited program do not think their completion of accreditation program influence their employment. Strategic approaches to make higher effectiveness of CAC accreditation system are suggested. First, improvement of curriculum and instruction method in CAC accredited program is required to satisfy the needs of students and industry. Second, efforts to inform students of understandings and necessity of accreditation are highly recommended. Third, industrial sector needs to understand CAC accreditation and give graduates from accredited program more incentives. Lastly, government support like Seoul Accord Activation Project should last for a while.

Ciglitazone is a member of the thiazolidinedione family, and specifically binds to peroxisome proliferator-activated receptor-γ (PPARγ), thereby promoting adipocyte differentiation. We hypothesized that ciglitazone as a PPARγ ligand in the absence of an adipocyte differentiation cocktail would increase adiponectin and adipogenic gene expression in bovine satellite cells (BSC). Muscle-derived BSCs were isolated from six, 18-month-old Yanbian Yellow Cattle. The BSC were cultured for 96 h in differentiation medium containing 5 µM ciglitazone (CL), 10 µM ciglitazone (CM), or 20 µM ciglitazone (CH). Control (CON) BSC were cultured only in a differentiation medium (containing 2% horse serum). The presence of myogenin, desmin, and paired box 7 (Pax7) proteins was confirmed in the BSC by immunofluorescence staining. The CL, CM, and CH treatments produced higher concentrations of triacylglycerol and lipid droplet accumulation in myotubes than those of the CON treatment. Ciglitazone treatments significantly increased the relative expression of PPARγ, CCAAT/enhancer-binding protein alpha (C/EBPα), C/EBPβ, fatty acid synthase, stearoyl-CoA desaturase, and perilipin 2. Ciglitazone treatments increased gene expression of Pax3 and Pax7 and decreased expression of myogenic differentiation-1, myogenin, myogenic regulatory factor-5, and myogenin-4 (p < 0.01). Adiponectin concentration caused by ciglitazone treatments was significantly greater than CON (p < 0.01). RNA sequencing showed that 281 differentially expressed genes (DEGs) were found in the treatments of ciglitazone. DEGs gene ontology (GO) analysis showed that the top 10 GO enrichment significantly changed the biological processes such as protein trimerization, negative regulation of cell proliferation, adipocytes differentiation, and cellular response to external stimulus. Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that DEGs were involved in the p53 signaling pathway, PPAR signaling pathway, biosynthesis of amino acids, tumor necrosis factor signaling pathway, non-alcoholic fatty liver disease, PI3K-Akt signaling pathway, and Wnt signaling pathway. These results indicate that ciglitazone acts as PPARγ agonist, effectively increases the adiponectin concentration and adipogenic gene expression, and stimulates the conversion of BSC to adipocyte-like cells in the absence of adipocyte differentiation cocktail.
