The decommissioning of one nuclear power plant in a multi-unit nuclear power plant (multi-unit NPP) site may pose radiation exposure risk to decommissioning workers. Thus, it is essentially required to evaluate the exposure dose of decommissioning workers of operating multi-unit NPPs nearby. The ENDOS program is a dose evaluation code developed by the Korea Atomic Energy Research Institute (KAERI). As two sub-programs of ENDOS, ENDOS-ATM to anticipate atmospheric transport and ENDOS-G to calculate exposure dose by gaseous radioactive effluents are used in this study. As a result, the annual maximum individual dose for decommissioning workers is estimated to be $2.31{\times}10^{-3}mSv{\cdot}y^{-1}$, which is insignificant compared with the effective dose limit of $1mSv{\cdot}y^{-1}$ for the public. Although it is revealed that the exposure dose of operating multi-unit NPPs does not result in a significant impact on decommissioning workers, closer examination of the effect of additional exposure due to actual demolition work is required. The calculation method of this study is expected to be utilized in the future for planned decommissioning projects in Korea. Because domestic NPPs are located in multi-unit sites, similar situations may occur.

Recombinant baculoviruses are widely used to express heterologous genes in cultured insect cells. Recombinant baculoviruses can serve as gene-transfer vectors for expression of recombinant proteins in a wide range of mammalian cell types. Baculovirus system has significant benefits in view of safety, large-scale, and high level of gene expression. In this study, baculoviral vectors which were reconstructed from pOPINEneo-3C-GFP vector, were recombined with cytomegalovirus (CMV) promoter, green fluorescent protein (GFP), and p53 with NcoI and XhoI. These recombinant vectors were infected with various cells and cell lines. The baculovirus vector thus developed was analyzed by comparing the metastasis and expression of the recombinant genes with conventional vectors. These results suggest that the baculovirus vector has higher efficiency in metastasis and expression than the control vector. This work was supported by a grant from Mid-Career Researcher Program(NRF-2016R1A2B4016552) through the National Research Foundation of Korea(NRF) funded by the Ministry of Science, ICT & Future Planning(MSIP).

Background: Ginseng is a traditional herbal medicine for human health. Ginseng contains a bioactive ligand named gintonin. The active ingredient of gintonin is lysophosphatidic acid C18:2 (LPA C18:2). We previously developed a method for gintonin-enriched fraction (GEF) preparation to mass-produce gintonin from ginseng. However, previous studies did not show the presence of other bioactive lipids besides LPAs. The aim of this study was to quantify the fatty acids, lysophospholipids (LPLs), and phospholipids (PLs) besides LPAs in GEF. Methods: We prepared GEF from white ginseng. We used gas chromatography-mass spectrometry for fatty acid analysis and liquid chromatography-tandem mass spectrometry for PL analysis, and quantified the fatty acids, LPLs, and PLs in GEF using respective standards. We examined the effect of GEF on insulin secretion in INS-1 cells. Results: GEF contains about 7.5% linoleic (C18:2), 2.8% palmitic (C16:0), and 1.5% oleic acids (C18:1). GEF contains about 0.2% LPA C18:2, 0.06% LPA C16:0, and 0.02% LPA C18:1. GEF contains 0.08% lysophosphatidylcholine, 0.03% lysophosphatidylethanolamine, and 0.13% lysophosphatidylinositols. GEF also contains about 1% phosphatidic acid (PA) 16:0-18:2, 0.5% PA 18:2-18:2, and 0.2% PA 16:0-18:1. GEFmediated insulin secretion was not blocked by LPA receptor antagonist. Conclusion: We determined four characteristics of GEF through lipid analysis and insulin secretion. First, GEF contains a large amount of linoleic acid (C18:2), PA 16:0-18:2, and LPA C18:2 compared with other lipids. Second, the main fatty acid component of LPLs and PLs is linoleic acid (C18:2). Third, GEF stimulates insulin secretion not through LPA receptors. Finally, GEF contains bioactive lipids besides LPAs.

This study was conducted to evaluate the factors affecting the quality of life before and after clinical practice for nursing students. The data were collected from 256 nursing students in the third and fourth years at H college and G University through a questionnaire from February 19 to June 29, 2018. The collected data were compiled using the SPSS/WIN 18.0 statistical program with Paired t-test, ANOVA, Spearman rho Correlation, Kendall Correlation, and Multiple Linear Regression. The factors that significantly explained the quality of life of nursing students before and after clinical practice were the reason for application (t=5.268, p<.001), school record (t=4.771, p<.001), depression (t=-4.600, p<.001), monthly income (t=3.383, p=.001), and satisfaction in nursing department (t=3.344, p=.001). The coefficient of determination for these factors, R2, showed an explanation force of 68.5%. These results also inferred that the quality of life of nursing college students is high, with high satisfaction in nursing departments and regular school record and low economic hardship and depression. Therefore, programs should be developed that can improve the quality of life of nursing students before and after clinical practice by continued improvement in the controllable factors of school record and satisfaction in nursing departments and by reducing depression, since the reason for application and the monthly income of nursing students cannot be controlled.

IFC(Industry Foundation Classes) is used for information exchange in BIM-based collaboration process, and it does not secure reliability of information exchange results between fields due to structural limitations. In the end, it is a realistic problem that we have to use specialized BIM software by field, and we can not secure smooth interoperability in the process of information exchange and change. This study was conducted to find ways to secure the interoperability of BIM work between architecture and structure fields by utilizing Open Source provided by software developers to solve these problems. First, through expert survey and in-depth interview, information and improvement factors required in the process of collaboration between architecture and structure were derived. Second, in order to find a solution to the improvement factors, existing studies related to Open-API and domestic and overseas APIs were investigated and analyzed. Third, Ad-On was developed to secure interoperability by using Open API, mainly BIM S/W, which is mainly used in each field. As a result of the study, the possibility of securing interoperability through the management of the design change history between fields was confirmed by using API. It is judged that the application range of API will be expanded to the construction and maintenance field in the future. Therefore, in order to increase the usability for application diffusion, further research on interface improvement through user-centered verification is needed.

During the 1960-1970s, a group of ceramic conservation scientists and ceramic historians in South Korea came together and established their own disciplines. While the two disciplines share the same ceramics as the subjects of their research, there has been little interaction between the two as their research outputs are articulated in remarkably different languages. This paper aims to address the following questions by using a case study that focuses on the research on white porcelains centered on the project of Gyeonggi Museum and a series of studies conducted by one of the museum's project research teams. First, what are the characteristics of and differences between the explanation styles of the two disciplines that share the same research subjects of ceramics? Second, why has the communication between the two disciplines become difficult? Third, if there can be a trading zone wherein the two disciplines would be able to communicate again, what would be its epistemic conditions? The focus of this paper is the relationship between scientific data and ordinary language, which the two disciplines have shared from their inception. By analyzing the relationship, I first argue that, as the analytical techniques of conservation science have become more developed, conservation science's data have gradually lost its relevance in ceramic history, in spite of a shared common language between them; Second, I argue that by recovering the import of shared language again, the scientific data can be placed in a different practical context, providing novel interpretations that are relevant and often consequential to ceramic history.
