Basic bioactivities (antioxidant, anti-inflammatory, antibacterial, anticancer, antiviral) were investigated from 370 strains of marine bacteria, fungi, and microalgae obtained from various marine environmental regions in Korea, and the activity results were obtained at the collection site, isolation source, and species level was compared. In the case of marine bacteria, strains belonging to the generally useful genera Streptomyces and Bacillus were observed to have particularly strong efficacy and useful resources were mainly isolated from marine sediments. In the case of marine fungi and microalgae, results showing strong species-specific activity were confirmed, and results showing efficacy-specific activity were also obtained. Based on these results, it is a research result that can facilitate priority access as a strategic material for industrial revitalization and the establishment of a strategy to secure resources based on usefulness when conducting research on chemicals that are selectively effective against specific diseases or when conducting resource-based research. In addition, we believe that by using these results as material for sale through the Marine BioBank (MBB), academia and industry can use them to help accelerate the revitalization of the marine bio industry.

This paper examines the characteristics of shared universities in Korea and seeks future development directions from the analysis of its operation. This study overviews the current status of students and the characteristics of each major in the DSC Shared University. This provides the future improvement direction and analyzes the survey of attending students. The results shows the most DSC students are engineering students, and they are taking classes centering on the major courses opened by their school. Future direction of shared universities include the recruitment of students from various backgrounds, expansions of enrollment in other schools' curriculum.

아직도 따가운 햇빛이 내려 쪼이는 초가을의 날씨, 이날따라 서울의대 구내는 조용하기만하다. 서울대학본부의 관악캠퍼스 이전 때문인지 마주보이는 구 문리대 본부건물이 마냥 쓸쓸하기만 하다. 그러나 연구의 전당으로서 의대건물은 너무나 의젖한 대조를 이룬다. 조용한 연구실에서 서울의대 기생충학 서병설 주임교수는 차분히 기자를 맞이해준다. 임상을 떠난 기초교실인 때문일까? 학자풍이 잔잔한 미소는 매서우면서도 온화하다.

The university administration building is one of the most important structure in campuses in terms of its functional roll providing all the institutional services and its symbolic value that represents the school. But we can still find many universities carrying on without administration buildings, And even though in the cases that have their own administration buildings, the architectural qualities of the buildings often can not meet the basic requirements for a worthwhile administration building. Because of its complex and complicated nature, planning and designing university administrative facilities are not an easy task to be successful. This study aims to provide the basic directions in designing university administration building through the survey of the facilities in the existing campuses.

The precipitates, hardness, and tensile properties of Al-6.2Si-2.9Cu AC2B alloy were investigated with respect to solution treatment time at $500^{\circ}C$. $Al(Cu)-Al_2Cu$ eutectic, Si, ${\theta}-(Al_2Cu)$, and $Q-(Al_5Cu_2Mg_8Si_6)$ phases were observed in the as-cast specimen. With increasing the solution treatment time at $500^{\circ}C$, the $Al(Cu)-Al_2Cu$ eutectic and ${\theta}-(Al_2Cu)$ phases were gradually reduced and finally almost disappeared in 5 h. The mechanical properties, such as hardness, tensile strength, and elongation, were improved with solution treatment time until about 5 h due to the dissolution of the $Al_2Cu$ particles. With further holding time, the mechanical properties did not change much. The solution treated specimens for over 5 h at $500^{\circ}C$ exhibit almost the same tensile properties even after aging at $250^{\circ}C$ for 3.5 h. Accordingly, the optimal solution treatment condition of the Al-Si-Cu AC2B alloy is considered to be 5 h at $500^{\circ}C$.

BACKGROUND: This study was aimed to determine characteristics of residues of the soil-treated boscalid and pyraclostrobin within Hylomecon vernalis and to evaluate the risks from intake of the residual pesticides in the crop. METHODS AND RESULTS: The pesticides were treated to soils at two different concentrations, and the plant samples were collected 57 days after seeding. The samples were extracted using the QuEChERS extraction kit (MgSO₄ 4 g, NaCl 1 g). The quantitative methods for boscalid and pyraclostrobin were validated using linearity, recovery, and CV (coefficient of variation). Risk assessment of the pesticides was performed using Korea national nutrition statistics 2019. CONCLUSION(S): The residual levels of boscalid were 0.02-0.05 mg/kg (for the treatment at 6 Kg/10a) and 0.05-0.08 mg/kg (for the treatment at 12 Kg/10a), respectively. The residual concentrations of pyraclostrobin were below the LOQ. The amounts of pesticides were less than Maximum Residue Limits specified by the Korean Ministry of Food and Drug Safety. The maximum hazard indices of boscalid in chwinamul and amaranth for consumers were 0.0075% and 0.1525%, respectively, and it indicates that the risk of the pesticides from the crop is considered to be low.
