  • 미국(CS2013)과 일본(J07-CS)은 고등교육의 수준에서 변화하는 사회를 반영하는 표준 정보교육과정을 구성하고 있다. 본 연구는 한국의 고등 정보교육과정 표준 구성에 대한 시사점을 제공하기 위해 미국의 표준교육과정 변화를 분석하고, 한국의 대학 교육과정 구성 현황 분석 및 내용 지식에 근거하여 과목을 구성하였다. 연구 진행 결과 미국의 고등 정보교육과정은 변화하는 컴퓨팅 환경을 반영하는 교육과정으로 진화하고 있었다. 국내 대학의 정보교육과정은 CS2013의 지식영역을 52% 정도만 포함하고 있었다. 본 연구는 일본의 교육과정 과목 구성방침에 근거하여 과목 구성의 예를 제시하였으며, 대학의 표준 정보 교육과정이 없는 상황에서 교육과정 구성을 위한 단초를 제공했다는 점에 의의를 두고 있다.

  • 21세기에 들어서 한국을 포함한 세계 각국은 정보교육에 대한 많은 변화를 시도하였다. 각국의 상황을 고려하여 정보교육의 필요성을 인지하고 실천적 행동으로 옮기고 있다. 본 연구는 다양한 명칭으로 논의되고 있는 정보교육의 모태학문인 정보학에 대해 고찰하기 위한 목적으로 진행되었다. 모태학문에 대한 고찰은 용어에 집중하여 학술논문과 고등교육기관의 학과명, 학술지에서 정보관련 용어의 출현빈도를 중심으로 분석하였다. 분석을 토대로 교과 '정보'는 사회적 변화에 기여하는 정보학을 모태학문으로 하고, 통합된 정보학은 모든 학문의 메타학문임을 제시하였다. 본 연구는 학문적인 측면 뿐 아니라 사회적 필요 측면에서 정보교육를 규명하고, 메타학문을 모태학문으로 하는 정보교육은 초중등 학교에서 필수로 가르쳐야 할 교과임을 시사점을 제공하였다.

  • The antimicrobial effect of a novel flavonoid (7-O-butyl naringenin) on Helicobacter pylori ATCC 26695 and its inhibitory effects on the urease activity of the strain were evaluated by comparing with quercetin and naringenin. H. pylori was cultured with brain heart infusion supplemented with 5% horse serum at $37^{\circ}C$ under 10% $CO_2$ atmosphere and the inhibitory effects of flavonoids against the strain were detected using micro-plate methods. During 12 hr of incubation time, the optical densities of phenol red reduced (pink color) in the urea broth by producing ammonia were detected at 560 nm with a spectrophotometer. The results indicated that both quercetin and 7-O-butyl naringenin were effective against the growth of H. pylori. Moreover, inhibitory effect of 7-O-butyl naringenin on the growth of H. pylori was about two-fold higher than quercetin at the same concentration. With regard to H. pylori urease activity, 7-O-butyl naringenin had a greater inhibitory effect than did naringenin or quercetin at the same concentration.

  • 고등교육의 질 관리를 중요하게 생각한 국가들은 다양한 제도나 방법을 통해 교육의 질 강화를 진행하고 있다. 컴퓨터과학 분야에서도 고등교육의 질 관리를 위해 교육과정 표준을 구성하는 등 끊임없이 노력해 왔다. 컴퓨터과학 분야 교육과정 표준에서 언급한 지식영역의 우선순위를 파악해 보면, 내용체계 구성에 시사점을 줄 수 있을 것이다. 따라서 CS2013을 토대로 내용요소에 대한 Tier1, Tier2, Elective의 시수와 세부영역의 수를 중심으로 순위를 도출하였다. 분석결과, 가장 높은 우선순위를 지닌 지식영역으로는 Software Development Fundamentals이었다. 해당 지식영역은 CS2013에서 기초 요소이기 때문에 초급코스로 권장한다고 기술되기도 하였다. 도출되어진 영역별 우선순위가 향후 초중등 정보교육과정이나 고등 교양 정보교육과정, 교원양성기관의 정보교육과정 설정에 시사점을 줄 수 있을 것이다.

  • The objective of this study was to investigate the anti-oxidative effects of taurine on sperm characteristics for in vitro storage of boar semen. Semen was randomly divided into 10 groups in conical tubes and treated with different concentrations of taurine (25-100 mM) with or without $250{\mu}M$ $H_2O_2$. The percentage of motile spermatozoa in taurine groups after 6 and 9 h were significantly higher at >94% and 87%, respectively, compared to the control group ($85.1{\pm}0.5$ and $72.4{\pm}0.3$, p<0.05). The sperm motility in taurine with $H_2O_2$ after 6 h incubation was slightly decreased compared to the taurine alone treatment, but after 9 and 12 h incubation % sperm motility dropped sharply in taurine with $H_2O_2$ ($75.3{\pm}0.3$ and $69.6{\pm}2.9$, p<0.05). For 3, 9 and 12 h incubation, sperm viability in the control was lower than in taurine groups, irrespective of taurine concentration. In eosin Y and nigrosin staining (ENS), the sperm survival rates (%) for 6 h incubation were significantly higher in 25 mM ($76.0{\pm}0.6$) and 50 mM taurine groups ($78.0{\pm}0.7$), respectively. Sperm survival rates for 9 and 12 h incubation were higher in taurine groups (${\geq}48%$ in 9 h and ${\geq}42%$ in 12 h) compared to controls ($43.0{\pm}2.1$ and $31.0{\pm}0.6$, respectively). In the hyoosmotic swelling test (HOST), sperm membrane integrity was similar to the results of sperm survival. These experiments indicate that supplementation of taurine to the semen extender can increase the sperm characteristics(motility, viability, survival and membrane integrity).

  • The impact of graphene and poly(methyl methacrylate) (PMMA) substrates on the response of a fiber Bragg grating (FBG) due to mechanical deflection was investigated. For this purpose, four FBGs with grating lengths of 5, 15, 25, and 35.9 mm were utilized. Higher sensitivity was found for FBGs of larger grating length and for those bonded to graphene substrate. It was concluded that FBGs of smaller grating length (5 and 15 mm) were more sensitive in compression mode, while those of larger grating length (25 and 35.9 mm) were seen to be highly sensitive in tension mode.

  • In contemporary education, the rapid advancement of digital technologies elevates demands for integrating the latest tools into the learning process. Mathematical analysis, as a discipline, benefits from computer mathematics in distance education, enhancing practical aspects and enabling individualized learning. This article addresses the integration of the Maple computer mathematics system into higher education, specifically in teaching "Mathematical Analysis." Emphasizing its role in distance learning, computer mathematics optimizes the educational environment, reducing the time required for knowledge acquisition. The article showcases the application of Maple in finding extremum points and introduces an educational software simulator, enabling students to practice the method. The simulator, developed within Maple, facilitates self-checking and enhances the study of functions. Conclusions drawn from the study highlight the positive impact of these tools on distance education, affirming Maple's role in enhancing professional training and information culture among higher education students.

  • Oxidative stress is one of the major causes of failure of in vitro storage of boar semen. Reactive oxygen species (ROS) are one of the important mediators of oxidative stress during in vitro storage of boar semen. Our study examined the effects of taurine on sperm characteristic and on in vitro developmental embryos during in vitro storage of boar semen for 7 days. Semen was randomly aliquoted into 3 centrifuge tubes and treated with different concentrations of taurine (25-100 mM). The characteristics of boar sperm were analyzed for motility by light microscopy, viability by using a Makler counting chamber and membrane integrity by a hypoosmotic swelling test (HOST). The percentages of motile spermatozoa in taurine groups after 5 days were significantly higher compared to the control. Sperm viability in the control was lower than in taurine groups after 7 days irrespective of different taurine concentration. In the hyoosmotic swelling test (HOST), significantly higher results were obtained in taurine groups after 3 days. Also, the developmental rates of IVM/IVF porcine embryos from semen treated with pyruvate and taurine were significantly increased when compared with the control (p<0.05). These results indicate that supplementation of taurine as an antioxidant in boar semen extender can improve the semen quality.

  • 이미지와 같은 고차원 데이터로부터 새로운 샘플 데이터를 생성하는 기술은 음성 합성, 이미지 변환 및 이미지 복원 등에 다양하게 활용되고 있다. 본 논문은 고해상도의 이미지들을 생성하는 것과 생성한 이미지들의 variation을 높이기 위한 방안으로 Progressive Growing of Generative Adversarial Networks(PG-GANs)을 구현 모델로 채택하였고, 이를 패션 이미지 데이터에 적용하였다. PG-GANs은 생성자(Generator)와 판별자(discriminator)를 동시에 점진적으로 학습하도록 하는데, 저해상도의 이미지에서부터 계속해서 새로운 레이어들을 추가하여 결과적으로 고해상도의 이미지를 생성할 수 있게끔 하는 방식이다. 또한 생성 데이터의 다양성을 높이기 위하여 미니배치 표준편차 방법을 제안하였고 GAN 모델을 평가하기 위한 기존의 MS-SSIM이 아닌 Sliced Wasserstein Distance(SWD) 평가 방법을 제안하였다.
