In response to a regulatory mandate, all nuclear licensees are obligated to establish an information system that can provide essential information in the event of a radiation emergency by connecting the monitoring data of the Safety Parameter Display System (SPDS) or equivalent system to the Korea Institute of Nuclear Safety (KINS). Responding to this responsibility, the Korea Atomic Energy Research Institute (KAERI) has established the Safety Information Transmission System (SITS), which enables the collection and real-time monitoring of safety information. The KAERI monitors and collects safety information, which includes data from the HANARO Operation Work Station (OWS) and the HANARO & HANARO Fuel Fabrication Plant (HFFP) Radioactivity Monitoring System (RMS), and the Environmental Radiation Monitoring System (ERMS) & meteorological data. Currently, the transmission of this safety information to the AtomCARE server of the KINS takes place via the SITS server located in the Emergency Operations Facility (EOF). However, the multi-path of transmission through SITS has caused problems such as an increase in data transmission interruptions and errors, as well as delays in identifying the cause and implementing system recovery measures. To address these issues, a new VPN is currently being constructed on the servers of nuclear facilities that generate and manage safety information to establish a direct transmission system of safety information from each nuclear facility to the AtomCARE server. The establishment of a direct transmission system that eliminates unnecessary transit steps is expected to result in stable information transmission and minimize the frequency of data transmission interruptions. As of the improvement progress, a security review was conducted in the second and third quarters of 2022 to evaluate the security of newly introduced VPNs to the nuclear facility server, and based on the results of the review, security measures were strengthened. In the fourth quarter of 2022, the development of a direct transmission system for safety information began, and it is scheduled to be completed by the fourth quarter of 2023. The project includes the construction of the transmission system, system inspection, and comprehensive data stability testing. Afterward, the existing SITS located in the EOF will be renamed as the Safety Information Display System (SIDS), and there are plans to remove any unused servers and VPNs.

Braveenth, Ramanaskanda,Lee, Hyuna,Kim, Sohyeon,Raagulan, Kanthasamy,Kim, Sunghoon,Kwon, Jang Hyuk,Chai, Kyu Yun The Royal Society of Chemistry 2019 Journal of materials chemistry. C, Materials for o Vol.7 No.25

<P>Two thermally activated delayed fluorescence (TADF) emitters with high synthetic yields were designed and synthesized. Both emitters, 10,10′-(5-(4,6-diphenyl-1,3,5-triazin-2-yl)-1,3-phenylene)bis(9,9-dimethyl-9,10-dihydroacridine) (TRZ-DDMAc) and 10,10′-(5-(4,6-diphenyl-1,3,5-triazin-2-yl)-1,3-phenylene)bis(9,9-diphenyl-9,10-dihydroacridine) (TRZ-DDPAc), showed excellent photophysical properties. Interestingly, both of the materials had a small energy difference between singlet and triplet levels, which confirmed that donor-acceptor based molecular design brought effective reverse intersystem crossing (RISC) to enable the TADF mechanism. The TADF characteristic was confirmed by a delay time of 10.32 and 10.37 μs for TRZ-DDMAc and TRZ-DDPAc, respectively. TRZ-DDPAc revealed a photoluminescence quantum yield of 79.7% in a doped film state. Moreover, several green OLED devices were fabricated by using different host materials along with various doping concentrations to ensure the optimal performance of each TADF material. The device with TRZ-DDPAc as an emitter (30%: DBFPO) exhibited excellent current and maximum external quantum efficiencies of 62.8 cd A<SUP>−1</SUP> and 27.3%, respectively. Green colour emission was observed from all devices, which originated through the TADF mechanism.</P>

We aimed to find out the effect of the social networks on the multifaceted health domains in the community-dwelling older adults. Studies that evaluated both structural and functional aspects of social networks were systematically reviewed. Through databases RISS, NDSL, PubMed, and Embase, articles from 2013 to 2023 were searched, and the final 16 studies were selected. Overall, non-standardized tools were used for evaluation, and various version of Lubben Social Network Scales were most commonly used. 28 factors derived from 16 studies were classified into four health domains: physical, mental, social, and subjective health. Factors such as physical frailty, depression, social role disability, quality of life were studied by domain. This study highlights the influence of the social networks on the multifaceted health of the elderly, and efforts are needed to develop multifaceted health intervention contents by utilizing social network in the future.

Ji Hyeun Park,Sangmi Park,Jae Hyu Jung,배수영,Sohyeon Yun,Anastassiya Khan,홍익표,박지혁 대한노인병학회 2023 Annals of geriatric medicine and research Vol.27 No.2

Background: Motoric cognitive risk syndrome (MCR) reduces the quality of life, independence, and social interaction in older adults. Social participation is a potentially modifiable factor that benefits cognitive and mental health. This study explored the mediating roles of social participation between MCR and depression and between MCR and loneliness. Methods: We performed a secondary analysis of data from the 2015–2016 National Social Life, Health, and Aging Project. Slow gait speed and cognitive decline were used to assess MCR. Mediation analysis was applied to two models, both of which used MCR as an exposure and social participation as a mediator. The outcomes were depression and loneliness for each model, respectively. Results: Among 1,697 older adults, 196 (11.6%) had MCR. The mediating role of social participation was statistically significant in both models. The indirect effect (β=0.267, p=0.001) of MCR on depression through social participation comprised 11.97% of the total effect (β=2.231, p<0.001). The indirect effect (β=0.098, p=0.001) of MCR on loneliness through social participation was 19.48% of the total effect (β=0.503, p<0.001). Conclusion: Interventions to increase social participation may reduce depression and loneliness of older adults with MCR.

Lee, Hanleem,Bak, Sora,An, Sung-Jin,Kim, Jung Ho,Yun, Eunbhin,Kim, Meeree,Seo, Sohyeon,Jeong, Mun Seok,Lee, Hyoyoung American Chemical Society 2017 ACS NANO Vol.11 No.12

<P>Thin-film transistors (TFTs) have received great attention for their use in lightweight, large area, and wearable devices. However, low crystalline materials and inhomogeneous film formation limit the realization of high-quality electrical properties for channels in commercial TFTs, especially for flexible electronics. Here, we report a field-effect TFT fabricated <I>via</I> cross-linking of edge-1T basal-2H MoS<SUB>2</SUB> sheets that are prepared by edge functional exfoliation of bulk MoS<SUB>2</SUB> with soft organic exfoliation reagents. For edge functional exfoliation, the electrophilic 4-carboxy-benzenediazonium used as the soft organic reagent attacks the nucleophilic thiolates exposed at the edge of the bulk MoS<SUB>2</SUB> with the help of an amine catalyst, resulting in 1T edge-functional HOOC-benzene-2H basal MoS<SUB>2</SUB> nanosheets (e-MoS<SUB>2</SUB>). The cross-linking <I>via</I> hydrogen bonding of the negatively charged HOOC of the e-MoS<SUB>2</SUB> sheets with the help of a cationic polymer, polydiallyldimethylammonium chloride, results in a good film formation for a channel of the solution processing TFT. The TFT exhibits an extremely high mobility of 170 cm<SUP>2</SUP>/(V s) at 1 V (on/off ratio of 10<SUP>6</SUP>) on SiO<SUB>2</SUB>/Si substrate and also a high mobility of 36.34 cm<SUP>2</SUP>/(V s) (on/off ratio of 10<SUP>3</SUP>) on PDMS/PET substrate.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2017/ancac3.2017.11.issue-12/acsnano.7b07776/production/images/medium/nn-2017-07776m_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn7b07776'>ACS Electronic Supporting Info</A></P>
