Various types of functional bedding for inducing and maintaining sleep, are developed and launched with the importance of improving health through sleep emphasized currently. The purpose of this study is to examine development status and direction of functional bedding in the 4th Industrial Revolution era, through systematic classification of elements of IoT-based smart bedding cases actively developed as functional bedding at home and  abroad. Through previous research, literature and Internet data,  characteristics and functional extension of smart bedding and the background of  smart bed development was analyzed. And it was analyzed that smart bedding pursues recent functionalism and convergence of physical and digital concept such as IoT or AI, and also mental value to improve sleep quality. As bedroom where smart bedding place in has the private and limited characteristics and users are in sleep-conscious, that hard to ensure power and discomfort in carrying are moderated and the aesthetic elements are not very important, and that the smart bedding performance while sleeping were affected on developmental background. Based on CES case study and analysis on how smart beds are functionally expanded from conventional bedding, smart beds have  gained information through digital sensing, and common properties that can be controlled anytime, anywhere, using a smart phone. Some set up the right environment and pose, while others stimulate nerves directly as active intervention. It is expected that smart bedding will be developed to cure user’s body and mind, through active intervention when sleeping.

Recyclable Thermosetting Polymers that Visualize Damage by Changing Optical Properties

윤수빈,김태안,방준하 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.2

Autonomous polymers that report damages prior to rupture and simultaneously self-heal are highly required for not only preventing catastrophic failures but also extending the lifetime use of the materials, thus ultimately keeping us on the path to sustainability. In this work, we demonstrate self-healable and re-processable thermosets that visualize damages in optical changes using spiropyrans (SPs) and thermoreversible Diels-Alder (DA) chemistry. SP, a well-studied mechanochromic molecules, is used as an initiator for the Atom Transfer Radical Polymerization. With SP-linked linear polymers, a remoldable thermoset is accomplished by adding reversible cross-linkers that efficiently generate DA adducts. Mechanical activation of SPs in DA polymeric networks is investigated both by density functional theory calculations and mechanical testing. We also investigate self-healing and thermomechanical properties after multiple recycling process.

Synthesis of β,γ-unsaturated ketones with quaternary centers through regioselective hydroacylation of allenes with acyl chlorides

윤수빈,이경민,Telma Kamranifard,이윤미 대한화학회 2022 Bulletin of the Korean Chemical Society Vol.43 No.12

The one-pot synthesis of β,γ-unsaturated ketones bearing all-carbon quaternary centers at the α-position via a highly regioselective hydroacylation of allenes using acyl chlorides and aluminum hydride is reported. The Cu-catalyzed hydroalumination of 1,1-disubstituted and 1,1,3-trisubstituted allenes with dii- sobutylaluminum hydride resulted in allylaluminum reagents that underwent regioselective acylation in the presence of acid chlorides. Various derivatives of allenes and acyl chlorides were compatible with this process, and α-quaternary ketones were obtained in high yields with excellent regioselectivity.

하천에서의 분광측정기를 이용한 TOC 모니터링 및 공간분포 분석 연구

윤수빈,이창현,김영도 한국수자원학회 2023 한국수자원학회논문집 Vol.56 No.11

수질오염 중 유기물 오염은 가장 흔히 발생한다. 물환경보전법에 의해 유기물질을 측정하는 지표에는 BOD, COD, TOC가 있다. 그 중 BOD, COD의 분석은 노동집약적이다. 그리고 생물분해가 불가능하거나 유독물질이 존재하는 유기물질일 경우에는 낮은 정확도를 나타내 환경부에서는 TOC 중심의 관리로 전환되고 있다. 오늘날 센서기술의 발전으로 다양한 항목을 센서를 통해 모니터링 가능하다. 본 연구에서는 분광측정기인 Spectro::lyser V3를 이용한 하천 TOC 디지털 모니터링을 진행했다. 우선 측정 장비에 대한 적용성 평가를 위해 안동하천실험센터에서 실험을 진행했다. 그리고 낙동강 합류부에서 측정한 데이터를 Kriging 기법을 활용하여 하천의 TOC 공간분포를 분석했다. 본 연구에서는 센서를 활용한 하천 TOC 모니터링 및 공간분포에 대한 연구를 제안했다. 실시간으로 하천 TOC 농도 변화를 모니터링 할 수 있으며, 이는 오염원 감시 및 대응에 있어 기초자료로 활용할 수 있다. 이러한 센서 기반 하천 모니터링은 시간적 해상도 및 실시간 데이터 취득에 있어 장점이 있는데, 다양한 공간 정보 해석 방법을 적용한다면 추후 수생태 건강성, 하천 취수원 선정, 성층 분석 등 다양한 연구에 기여할 수 있을 것으로 기대된다. Organic pollution is one of the most common forms of water contamination. Under the Water Quality Conservation Act, indicators for measuring organic substances include BOD, COD, and TOC. Analysis of BOD and COD is labor-intensive, and in the case of organic substances where biological decomposition is not feasible or toxic substances are present, the accuracy is often low. Therefore, the Ministry of Environment is shifting towards TOC-centric management. With advancements in sensor technology today, various parameters can be monitored using sensors. In this study, digital monitoring of river TOC using a spectrophotometer called Spectro::lyser V3 was conducted. Initially, experiments were carried out at the Andong River Experiment Center to assess the applicability of the measurement equipment. Subsequently, data collected at the confluence of the Nakdong River was analyzed for the spatial distribution of TOC using the Kriging technique. This research proposes the utilization of sensors for river TOC monitoring and spatial distribution analysis. Real-time monitoring of changes in river TOC concentration can serve as fundamental data for pollution monitoring and response. Sensor-based river monitoring offers advantages in terms of temporal resolution and real-time data acquisition. When various spatial information interpretation methods are applied, it is expected to contribute to diverse studies such as aquatic ecological health, river water source selection, and stratification analysis in the future.

Bile salt hydrolase-mediated inhibitory effect of Bacteroides ovatus on growth of Clostridium difficile

윤수빈,유준선,Andrea McDowell,김성호,유현주,고광표 한국미생물학회 2017 The journal of microbiology Vol.55 No.11

Clostridium difficile infection (CDI) is one of the most common nosocomial infections. Dysbiosis of the gut microbiota due to consumption of antibiotics is a major contributor to CDI. Recently, fecal microbiota transplantation (FMT) has been applied to treat CDI. However, FMT has important limitations including uncontrolled exposure to pathogens and standardization issues. Therefore, it is necessary to evaluate alternative treatment methods, such as bacteriotherapy, as well as the mechanism through which beneficial bacteria inhibit the growth of C. difficile. Here, we report bile acid-mediated inhibition of C. difficile by Bacteroides strains which can produce bile salt hydrolase (BSH). Bacteroides strains are not commonly used to treat CDI; however, as they comprise a large proportion of the intestinal microbiota, they can contribute to bile acid-mediated inhibition of C. difficile. The inhibitory effect on C. difficile growth increased with increasing bile acid concentration in the presence of Bacteroides ovatus SNUG 40239. Furthermore, this inhibitory effect on C. difficile growth was significantly attenuated when bile acid availability was reduced by cholestyramine, a bile acid sequestrant. The findings of this study are important due to the discovery of a new bacterial strain that in the presence of available bile acids inhibits growth of C. difficile. These results will facilitate development of novel bacteriotherapy strategies to control CDI.

The purpose of this study is to see changes in social skills and problematic behaviors of children with developmental disabilities through this experimental study. We recruited twenty children diagnosed as having developmental disabilities aged between 6 and 13. Before this study started, the data were collected through interviews with their legal guardians and preparation of a preliminary examination. Ten participants were assigned to the experimental group, and other ten participants to the control group in order to examine differences in social skills and problematic behaviors before and after participating in the 12-week rhythmic Taekwondo program. The rhythmic Taekwondo program was provided three times a week and lasted for 1 hours per day. The results indicated that the experimental group shows significant differences in the social competence scale after participation in the program compared to before participation in the program, while the control group showed no significant differences in the scale. Another results indicated that the experimental group shows significant differences in all sub-categories of the problem behavior scale except the rule violation after the program, while the control group did not show significant differences in any sub-categories of the scale. Through this study, we believe that the rhythmic Taekwondo program seems to become a good opportunity to improve social competence and reduce problematic behaviors of children with developmental disabilities.
