기존공동주택의 발코니 배수소음 저감용 드레인 덮개 시제품 적용 연구

송민정,강민우,오양기 한국소음진동공학회 2019 한국소음진동공학회 논문집 Vol.29 No.5

Balcony drainage noise in existing apartments is one of the facility noises subject to civil petition, next to the floor impact sound for residents. Newly constructed apartment houses have separate discharge systems for rainwater and drainage, thus, the drainage sounds of upper house are blocked by the lower house. However, as the structure of balcony drainpipes of apartments built before 2006 incorporate rainwater and drainage, residents are continuously complaining about the balcony drainage sounds. To reduce existing apartment balcony drainage noise, studies have been conducted in which drain covers were constructed at the location of maximum noise as a measure to identify the maximum location of drainage noise among the drainage pipes. Based on the results of previous researches, several additional components are designed and created that can be added to existing commercial products and are easy to apply to existing drainage pipes. Furthermore, they have been designed to be easy to detach and maintain, and were precisely manufactured and applied to actual apartments for performance testing. As a result, if a plastic member with a thickness of 5mm is added to an existing commercial product, the reduction is estimated to be around 13dB. This can reduce drainage noise in daily life to approximately 45dB, which will help create a quiet living environment for existing apartment inhabitants.

Web3 Business Model Innovation Approach and Cases of Korean Game Giants

송민정 한국인터넷방송통신학회 2024 International Journal of Internet, Broadcasting an Vol.16 No.1

We analyze the types of Web3 business model innovation (BMI) of the six major Korean game companies by market size. As a result of the analysis, Nexon is watched as the adapter. It introduces blockchain (BC) layer 2, ‘Polygon’ to the extended ecosystem such as the creator’s secondary creation, item utility, and compensation experience using the existing core intellectual property (IP). KakaoGames and Neowiz are watched as the adventurers. KakaoGames introduces BC layer 2, ‘Polygon’ and ‘Near Protocol’ to various experiments using tokenomics models in casual games and massively multiplayer online role-playing games (MMORPGs) using several existing popular IPs. Neowiz also introduces BC layer 2, ‘Polygon’ and ‘Avalanche’ to the IntellaX platform using existing game IPs. As the reinventor, Netmable positions as a game publisher that releases third-party games based on multi-chain infrastructure such as Klaytn, BNB Chain, Near Protocol, Aptos Foundation, and introduces BC to new core IPs. Finally, there are Wemade and Com2us as the mavericks. They aim to be the Web3 platform operators that create a BC layer 1 ecosystem and provide services that encompass BC games, GameFi, and non-fungible tokens (NFTs). Here are the implications of the four types of BMI. In terms of infrastructure, Nexon, KakaoGames, and Neowiz try to introduce a part of cross-chain, whereas Netmable tries to move toward a complete multi-chain strategy, and Wemade and Com2us also try to consider multi-chain, even if they have the full BC introduction. In terms of defending against market decline, Nexon and Netmable have a different position. Nexon which has a greater market dominance, only tries to continuously experiment, but Netmable is aggressively focusing on monetizing new products. Attacks on growth aspirations also show two different positions. KakaoGames and Neowiz only try to aggressively explore, while WeMade and Com2us try to set new standards for industrial innovation.

CuO Nanoparticles/polyaniline/CNT fiber 유연 전극 기반의 H2O2 검출용 비효소적 전기화학 센서

송민정 한국화학공학회 2023 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.61 No.2

In this study, a CNT fiber flexible electrode grafted with CuO nanoparticles (CuO NPs) and polyaniline (PANI) was developed and applied to a nonenzymatic electrochemical sensor for H2O2 detection. CuO NPs/PANI/CNT fiber electrode was fabricated through the synthesis and deposition of PANI and CuO NPs on the CNT fiber surface using an electrochemical method. Surface morphology and elemental composition of the CuO NPs/PANI/CNT fiber electrode were characterized by scanning electron microscope with energy dispersive X-ray spectrometry. And its electrochemical characteristics were investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA). Compared with a bare CNT fiber as a control group, the CuO NPs/PANI/CNT fiber electrode showed a 4.78-fold increase in effective surface area and a 8.33-fold decrease in electron transfer resistance, which leads to excellent electrochemical properties such as a good electrical conductivity and an efficient electron transfer. These improved characteristics were due to the synergistic effect through the grafting of CNT fiber, PANI and CuO NPs. As a result, this electrode enhanced the H2O2 sensing performance. 우리는 금속 산화물 CuO nanoparticles (CuO NPs)과 전도성 고분자 Polyaniline (PANI)가 접목된 CNT fiber 유연전극 (CuO NPs/PANI/CNT fiber 전극 )을 개발하여 H2O2 검출용 비효소적 전기화학센서에 적용하였다 . CNT fiber 표면 위에 PA N I와 CuO NPs을 전기화학적 합성 /증착을 통해 제작된 CuO NPs/PANI/CNT fiber 전극은 주사전자 현미경(SEM)과 에너지분산형 분광분석법 (EDS)을 통해 표면 분석이 수행되었으며 , 순환전압 전류법 (CV)과 전기화학 임피던스법 (EIS), 시간대전류법 (CA)을 이용하여 전기화학적 특성 및 H2O2 센싱 성능이 분석되었다 . CuO NPs/PANI/CNT fiber 전극은 대조군인 bare CNT fiber 전극과 비교하여 약 4.78배의 유효 표면적 증가를 보였으며 , 약 8.33배의 전자전달 저항 (Ret) 감소로 인한 우수한 전기 전도성 및 효율적인 전자전달 등의 전기화학적 특성을 나타냈다 . 이런 향상된전극 특성은 CuO NPs와 PANI의 접목을 통한 시너지 효과에 기인한 것으로 , 결과적으로 H2O2 검출에 대한 센싱 성능이 개선되었다 .
