To investigate the anti-inflammatory activity of submerged culture using Cordyceps militaris mycelium, culture-including mycelia was extracted and lyophilized into postbiotics (hot-water extract; CM-HW). HW was fractionated into crude polysaccharide (CM-CP) by ethanol precipitation, and CM-CP was further dialyzed into CM-DCP by dialysis with running water using 12~14 kDa dialysis tube. When the cytotoxicity of subfractions against cells was assessed, no subfraction had a cytotoxic impact that was substantially different from the control groups. In an inflammatory model using LPS-stimulated RAW 264.7 cells, CM-DCP significantly decreased IL-6 and MCP-1 production levels compared to the LPS-control group. CM-DCP also inhibited IL-6 and IL-8 secretion in HaCaT keratinocytes stimulated with TNF-α and IFN-γ. In the meanwhile, the neutral sugar content and mannose ratio of anti-inflammatory CM-DCP were higher than the other fractions, and CM-DCP contained β-1,3/1,6-glucan of 216.1 mg/g. High pressure size exclusion chromatography revealed that CM-DCP contained molecules with a molecular weight range of 5.6 to 144.0 kDa. In conclusion, postbiotics of C. militaris mycelium significantly promoted anti-inflammatory activity, suggesting that neutral polysaccharides including Glc and Man contribute to the anti-inflammation in RAW 264.7 or HaCaT cells.

This study is an analysis of the relationship between self leadership and self-efficacy in learning for Chinese students majoring in beauty. It is a research article that describes the factors that affect self-efficacy in learning. From July to October 2019, 440 Chinese students were investigated with questionnaires to collect data. The results show that the inferior factors of self leadership of Chinese students majoring in beauty are: The results showed that behavior awareness & volition, and constructive cognition, which are the Subfactor of Chinese students in beauty major, had a significant positive influence on the task difficulty preference and self-regulatory efficacy of self-efficacy. Therefore, raising the level of behavior awareness & volition, and constructive cognition of Chinese students in beauty majors can help Chinese students in beauty majors to acquire major knowledge and professional strength. In particular, In university education, we can provide systematic curriculum education on self-leadership understanding and strategy for Chinese students.

현재의 메타버스 서비스는 메타버스 학술대회, 메타버스 입학식 등과 같이 단순히 실제 세계의 대체품 역할만을 수행하고 있으며 앞으로의 메타버스는 실제 세계와 가상 세계가 융합된 실·가상 융합형 메타버스 서비스로 발전할 것이다. 실제 세계와 가상 세계가 융합하기 위해서는 실제 세계에 존재하는 다양한 물리적 개체의 정보가 가상 세계로 반영되어야 하며 메타버스 서비스의 규모가 증가함에 따라 높은 확장성을 지원하는 통신 기술이 요구된다. 본 논문에서는 높은 확장성의 통신 미들웨어인 DDS와 시간 확정적 전송을 보장하는 TSN 표준을 융합하여 메타버스 서비스가 요구하는 방대한 데이터를 시간 확정적으로 전송할 수 있는 DDS-TSN 계층 구조를 설계한다.

This study is convergence study about the effect path of relationship among satisfaction with biological nursing science, satisfaction with major nursing subject, critical thinking disposition, satisfaction with major and clinical competence. The survey was performed on 203 nursing students in three college. Data was collected using a structured questionnaires in May 2018 and analysed with PASW 18.0 and AMOS 18.0. Model fit indices were in good agreement with recommended level(${\chi}^2/DF=1.093$, GFI=.992, AGFI=.968, RMSEA=.021, CFI=.998, NFI=.983). Base on the path model, satisfaction with biological nursing science showed a direct effect on satisfaction with major nursing subject(${\beta}=.345$), satisfaction with major nursing subject showed a direct effect both on critical thinking disposition(${\beta}=.272$) and satisfaction with major(${\beta}=.277$), critical thinking disposition showed a direct effect both on satisfaction with major(${\beta}=.365$) and clinical competence(${\beta}=.582$), satisfaction with major a direct effect on clinical competence(${\beta}=.228$). In conclusion the biological nursing science satisfaction has eventually improved clinical competence. Therefore, it is necessary to develop and apply various teaching methods that can increase satisfaction with biological nursing science.

This study is to find the converging effects of the Complete Sciences Subjects(CSS) in high school before entrance to University on the scores of Basic Nursing Sciences(BNS) and Major Nursing Subjects(MNS) of 111 senior nursing students of one university. Using the SPSS 19.0, t-test, Pearson's correlation coefficient, multiple and simple linear regression were carried out. The mean scores of the groups that have completed the subjects of Biology I & II, Chemistry I & II were high on Anatomy, Physiology and Pathology. There was a significant difference between the group of completed Biology II and incompleted Biology II on the mean scores of MNS(p<.05). There were positive correlations between the CSS and the scores of BNS and MNS, a moderate correlation between Chemistry II and BNS(r=.303) and a strong correlation between BNS and MNS(r=.796). Explanation rate of CSS on the scores of BNS, and MNS were 18.2%, 8.2% respectively, and on the scores of BNS on MNS was 63.8%. The result of this study can be used in assessing university entrance procedure after repeated study, extended location and more participants, and to use for making pre-school program for the freshmen who didn't CSS.

The purpose of this study was to investigate the perceptions of faculty as a foundation for establishing a convergence education model at N-University. In September 2019, a survey was conducted using an online survey system, and a total of 80 responses were obtained. SPSS 23 was used for analysis, and a t-test, ANOVA, and multiple regression analysis were performed. First, the female faculty were significantly more positive about linked-major expansion than were the male faculty. Second, assistant faculty were significantly more positive about convergence curriculum establishment than were associate faculty. Third, as a result of the multiple regression analysis, the preference for multimajor expansion was the most significant and positively influencing factor on the convergence curriculum establishment. Universities must provide various incentives to form a consensus among university faculty. The Ministry of Education must support individual universities through the establishment of clearer guidelines and a kind of convergence education support center.

This study attempted to identify convergence effect factors affecting career-preparation behavior among nursing students with clinical practice. Study participants were 159 students in D city and data were collected from September 25 to October 4, 2014. Participants' responses were analyzed using a stepwise regression analysis. As results, satisfaction with major, professional values, and positive psychological capital were positively correlated with career-preparation behavior. Significant and convergence predictors of career-preparation behavior were curriculum satisfaction, a subdomain of major satisfaction, and social awareness as a professional value. These findings showed that nursing students' career-preparation behavior was partly determined by major satisfaction and nursing professional values. positive psychological capital need to be investigated as a convergent influence factor of career preparation behavior of nursing students by further study.

일본 우주항공연구개발기구(Japan Aerospace Exploration Agency, JAXA)는 2007년부터 2017년까지 달 탐사선 셀레네(Selenological and Engineering Explorer, SelEnE)가 관측한 데이터를 수집하고, 연구했다. JAXA는 지구 상층 대기에 존재하는 산소가 자기장의 꼬리 부분에 실려 달로 이동한다는 사실을 발견했다. 하지만 이 연구는 아직 진행 중이며 달의 산화 과정 규명에 추가 연구가 필요하다. 본 논문에서는 생성적 적대 신경망(Generative Adversarial Networks, GAN)으로 달 분화구의 영구 그림자 영역을 제거하고, 물과 얼음을 발견하여 선행 연구의 완성도를 향상하고자 한다. 실험에 사용할 모델은 CIPS(Conditionally Independent Pixel Synthesis)다. CIPS는 실제 같은 영상을 고해상도로 합성한다. 합성할 데이터의 최적인 가중치 초기화 및 파라미터 갱신 방법, 활성 함수 조합은 실험을 통해 확인한다. 필요에 따라 앙상블 학습을 할 수도 있다. 성능평가는 FID(Frechet Inception Distance), 정밀도, 재현율을 사용한다. 제안한 방법은 진행 중인 연구의 시간과 비용을 절약하고, 인과관계를 더욱 명확히 밝히는 데 도움 될 수 있다고 사료된다.

망막혈관 영상에서(retinal image) 혈관의 모양 또는 생성변화를 효과적으로 검진하기 위해서 망막혈관을 자동적으로 분리하는 영상분할 기법의 개발은 매우 중요한 사안이다. 이를 위해서 주로 망막혈관영상의 잡음을 억제하고 또한 혈관의 명암대비도(contrast)를 증가시키는 전처리 과정을 거쳐서 혈관의 국부적인 화소값의 변화, 방향성을 판별하여 혈관을 자동적으로 검출하는 방법들이 제시되어왔으며 최근에는 합성곱 신경망(CNN) 딥러닝 학습모델을 활용한 망막혈관 분리 알고리즘들이 제시되고 있다.
