  • 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.

  • Background: Recently, plant-derived exosome-like nanoparticles (PDENs) have been isolated, and active research was focusing on understanding their properties and functions. In this study, the characteristics and molecular properties of ginseng root-derived exosome-like nanoparticles (GrDENs) were examined in terms of skin protection. Methods: HPLC-MS protocols were used to analyze the ginsenoside contents in GrDENs. To investigate the beneficial effect of GrDENs on skin, HaCaT cells were pre-treated with GrDENs (0-2 × 109 particles/mL), and followed by UVB irradiation or H2O2 exposure. In addition, the antioxidant activity of GrDENs was measured using a fluorescence microscope or flow cytometry. Finally, molecular mechanisms were examined with immunoblotting analysis. Results: GrDENs contained detectable levels of ginsenosides (Re, Rg1, Rb1, Rf, Rg2 (S), Gyp17, Rd, C-Mc1, C-O, and F2). In UVB-irradiated HaCaT cells, GrDENs protected cells from death and reduced ROS production. GrDENs downregulated the mRNA expression of proapoptotic genes, including BAX, caspase-1, -3, -6, -7, and -8 and the ratio of cleaved caspase-8, -9, and -3 in a dose-dependent manner. In addition, GrDENs reduced the mRNA levels of aging-related genes (MMP2 and 3), proinflammatory genes (COX-2 and IL-6), and cellular senescence biomarker p21, possibly by suppressing activator protein-1 signaling. Conclusions: This study demonstrates the protective effects of GrDENs against skin damage caused by UV and oxidative stress, providing new insights into beneficial uses of ginseng. In particular, our results suggest GrDENs as a potential active ingredient in cosmeceuticals to promote skin health.

  • Developing countries face numerous challenges in the process of building science, technology, and research capacity; in particular, the formation and accumulation of skilled S&T workforce. The lack of organized and sustainable higher education options (Master and Doctoral programs), nonexistent or low-quality academic programs, and the absence of research-oriented study options are some of the strong contributors for talented students to emigrate to developed countries. At the same time, the consolidation of a global knowledge economy, the internationalization of higher education, and the competition to attract foreign talent in industrialized countries present challenges for underdeveloped nations to retain their already scarce skilled human resources. In this context, student mobility has been used as a policy mechanism to cope with S&T workforce shortages in S&T laggard nations. It has also enabled opportunities for international cooperation to play a key role. While significant literature has been devoted to studying the gains of developed nations with the arrival and potential migration of the mobilized students, few scholarly inquiries have addressed the benefits and losses experienced by their countries of origin. More importantly, limited research can be found on policy options and policy implications for developing countries to deal with the dilemmas presented by the brain-drain/brain-circulation debate. The goal of this article is to study empirical evidence of an international cooperation initiative for student mobility between the Republic of Korea and Guatemala (implemented during 2009-2015). The paper analyzes this particular international cooperation experience from the perspective of the different actors involved and attempts to draw policy implications and policy options for developing countries to deal with potential risks and gains derived from international mobility for their S&T capacity building.

  • This paper identifies the aspects of living environment elements (PM2.5, PM10, Noise) throughout Seoul and the urban characteristics that affect them by utilizing the big data of the S-Dot sensors in Seoul, which has recently become a hot topic. In other words, it proposes a big data based urban computing research methodology and research direction to confirm the relationship between urban characteristics and living environments that directly affect citizens. The temporal range is from 2020 to 2021, which is the available range of time series data for S-Dot sensors, and the spatial range is throughout Seoul by 500mX500m GRID. First of all, as part of analyzing specific living environment patterns, simple trends through EDA are identified, and cluster analysis is conducted based on the trends. After that, in order to derive specific urban planning factors of each cluster, basic statistical analysis such as ANOVA, OLS and MNL analysis were conducted to confirm more specific characteristics. As a result of this study, cluster patterns of environment elements(PM2.5, PM10, Noise) and urban factors that affect them are identified, and there are areas with relatively high or low long-term living environment values compared to other regions. The results of this study are believed to be a reference for urban planning management measures for vulnerable areas of living environment, and it is expected to be an exploratory study that can provide directions to urban computing field, especially related to environmental data in the future.

  • This study aims to examine the effects of consumption values on digital convergence products buying behavior. Especially, this study examines the nature of consumption values that differentiate incremental innovation products from radical innovation product. We first categorize the convergence products into incremental innovation products and radical innovation products based on the degree of innovation, and then study the differences of consumption values of each product group. The empirical research is conducted on the premise that the consumer's value can play an important role in the process of selecting convergence product types. Although some factors related to function value has been accounted much of, various consumer values have not been studied in the context of convergence product consumption behavior. This research assumes that consumer choice behavior is a function of multiple consumption values such as functional value, social value, emotional value, and epistemic value. The result shows that consumption values of digital convergence products are made up of 4 consumption values-emotional, epistemic, social and functional values. Also, these consumption values affect the purchase intention of consumers. Purchase intention of radical innovation convergence products is affected by emotional value, epistemic value, and functional values. Purchase intention of incremental innovation convergence products is affected only by functional value. Demographic variables such as sex, age and income don't have influence on purchase intention. Our findings suggest that choice behavior of digital convergence product is influenced by several consumption values. Managerially, our result emphasize that convergence products must satisfy the consumption values that consumers are seeking in order to be successful in the market. the theoretical and practical implications of these findings are discussed as well.

  • Background Chitosan (CS) is a well-known antimicrobial dressing material. Moreover, widely used amniotic membranes contain growth factors beneficial for wound healing. Herein, we created a novel amnion-conjugated CS-alginate membrane dressing and tested its wound healing potency in a diabetic swine model. Methods The bovine amniotic powder growth factor contents were evaluated by protein assay, and the powder's wound healing effects were assessed in vitro by HaCaT cell scratch closure. In vivo, two minipigs developed streptozotocin-induced diabetes. Serial serum glucose measurements and intravenous glucose tolerance tests were performed to confirm their diabetic status. Twelve square-shaped wounds created on each pig's back were randomly divided into control (n = 4), CS (n = 4), and amnion-CS (AC; n = 4) groups and treated accordingly with different dressings. Wound healing in each group was assessed by measuring wound contraction over time, capturing wound perfusion with indocyanine green (ICG) angiography, and histologically analyzing inflammatory markers. Results Amniotic powder elution promoted HaCaT cell migration in the scratch wound model, suggesting its beneficial in vitro wound healing effects. In vivo, the CS and AC groups showed earlier wound contraction initiation and reepithelialization and earlier wound perfusion improvement by ICG angiography than the control group. Additionally, the wound size of the AC group at week 3 was significantly smaller than those in the control group. There was no significant difference in the numbers of acute and chronic inflammatory cells between the groups. Conclusion The amnion-conjugated CS-alginate membrane, as well as CS dressing alone, could be a favorable dressing option for diabetic wounds.
