In this paper, as there are many cases of fires occurring due to the failure or inoperability of the thermostat of electronic products, the purpose is to test and analyze the risks and probabilities through fire cases and reproduction experiments, and suggest countermeasures. Among electronic products, water purifiers are composed of a refrigerant system with a compressor to make cold water, a heating device to make hot water, and an electric device used as an energy source. Due to the nature of the water purifier manufacturing, these devices are subject to a lot of moisture and dust. etc. exist in large quantities and use electrical energy, so there is a possibility of fire due to short circuit in the wire, electrical abnormal overheating (tracking phenomenon) in the thermostat, electronic board, starting relay, etc., and overheating of the heating device (Band Heater). there is. Therefore, in order to prevent fires from these devices, a system to remove foreign substances inside the water purifier is necessary, the use of heat-resistant (fire-resistant) wires for electrical devices is essential, and the use of non-combustible materials (semi-combustible materials) for each part is necessary to prevent fire. The risk must be eliminated through prevention and combustion expansion prevention devices.

Organoleptic parameters such as color, odor, and flavor influence consumer perception of drinking water quality. This study aims to evaluate the taste of the selected bottled and tap water samples using an electronic tongue (E-tongue) instead of a sensory test. Bottled and tap water's mineral components are related to the overall preference for water taste. Contrary to the sensory test, the potentiometric E-tongue method presented in this study distinguishes taste by measuring the mineral components in water, and the data obtained can be statistically analyzed. Eleven bottled water products from various brands and one tap water from I city in Korea were evaluated. The E-tongue data were statistically analyzed using multivariate statistical tools such as hierarchical clustering analysis (HCA), principal component analysis (PCA), and partial least squares discriminant analysis (PLS-DA). The results show that the E-tongue method can clearly distinguish taste discrimination in drinking water differing in water quality based on the ion-related water quality parameters. The water quality parameters that affect taste discrimination were found to be total dissolved solids (TDS), sodium (Na+), calcium (Ca2+), magnesium (Mg2+), sulfate (SO4 2-), chloride (Cl-), potassium (K+) and pH. The distance calculation of HCA was used to quantify the differences between 12 different types of drinking water. The proposed E-tongue method is a practical tool to quantitatively evaluate the differences between samples in water quality items related to the ionic components. It can be helpful in quality control of drinking water.

현행 전자금융거래법 상 전자금융업종은 시행 16년이 지나 낡았고, 지나치 게 세분화되고 경직돼 있다. 이로 인해 최근의 전자금융시장과 업계의 현실 을 유연하고 탄력성 있게 반영할 수 없는 문제점을 노출하고 있다. 업종을 지나치게 세세하게 구분하다 보니, 동일한 기능임에도 불구하고 서로 다른 업종으로 분류되어 다른 규제가 적용되고 있다. 역외 적용 측면에서도 해외 전자금융업체에 적용하기 힘든 상황이다. 게다가 혁신적인 핀테크 서비스의 출현을 제도적으로도 뒷받침하지 못하게 해 우회적인 편법 영업을 만연하게 하는 현상마저 낳고 있다. 전자금융업종은 전자금융거래법의 핵심 규율체계이다. 글로벌 스탠다드에 맞는 원칙과 기준을 확립해 시장에 적합한 전자금융업종의 통합ㆍ개편을 시 급히 추진해야 할 것으로 본다. 먼저 전자금융업종 설계의 기본이 되는 전 자지급수단에 대한 개념정의와 종류를 외국 선진법제처럼 포괄적(네거티브) 탄력적으로 설계해 나가는 것이 바람직하다고 본다. 전자지급수단을 기능 및 역할이 동일 유사한 형태끼리 통합하고 스테이블코인의 경우도 선불전자 지급수단으로 포섭하는 것을 검토해야 할 것으로 본다. 전자금융업종에 대해서도 EU, 일본처럼 원칙과 기능 중심으로 포괄적 설계 를 하는 것이 바람직해 보인다. 핀테크 등 혁신기업의 범위도 전자금융거래 법에서 이를 명확히 할 필요도 있다. 신생 혁신기업의 진입 활성화와 경쟁 촉진을 위해 Sliding Scale 제도나 스몰라이센스의 도입도 필요하다. 종합 지급결제사업자의 도입도 적극 검토할 필요가 있다. 전용 계좌와 연계된 고 객의 결제 관련 각종 데이터의 독자적 확보와 활용을 가능하게 해줘 다양한 부가 사업에 나설 수 있게 해줄 뿐만 아니라, 마이데이터의 고도화도 가능 해지기 때문이다. 오픈파이낸스 시대에 오픈뱅킹과 마이페이먼트의 법제화 도 시급하다. 현행 선불업자에 대한 규제도 공정거래위원회의 신유형상품권 표준약관과 규제 대상 중복문제와 자가형 발행업자들인 대형 백화점, 유통업체, 항공사 등이 배제되는 형평성 문제도 해소할 필요가 있다. 소액후불결제업무는 신 용공여가 주목적이 아니고 포용금융, 대안금융, 금융데이터사업의 성격이 강 한 만큼 소액후불결제의 혁신성, 이용자 후생 증진에 무게를 두고 전자금융 거래법 틀 내에서 세부 행위규제를 새로 설정하는 것이 바람직하다고 생각 한다. 전자금융보조업자들을 시장에 명확히 공개(공시)하여 금융회사·전자금융업자 의 전자금융보조업자에 대한 계약과 간접 감독에 만전을 기하고 전자금융보 조업자의 업무범위와 책임관계를 명확히 할 필요가 있다. 유럽 PSD2, PSD3, 일본 자금결제법에서처럼 전자지급거래 청산기관의 제 도화를 위해 해당 법 규정을 전자금융거래법에 반영하는 것도 바람직할 것 으로 본다. 그리고 전자금융거래법에 역외적용을 강화하는 내용을 반영, 국 내 사업자와의 형평성, 자국민(기업) 보호 차원에서 소비자보호를 위한 행위 규제, 진입규제 등은 강행규정으로서 행위 주체의 소재 국가와 상관없이 적 용되어야 할 것으로 본다.

Epoxy-based composites find extensive application in electronic packaging due to their excellent processability and insulation properties. However, conventional epoxy-based polymers exhibit limitations in terms of thermal properties and insulation performance. In this study, we develop epoxy-based siloxane/silica composites that enhance the thermal, mechanical, and insulating properties of epoxy resins. This is achieved by employing a sol–gelsynthesized siloxane hybrid and spherical fused silica particles. Herein, we fabricate two types of epoxy-based siloxane/ silica composites with different siloxane molecular structures (branched and linear siloxane networks) and investigate the changes in their properties for different compositions (with or without silica particles) and siloxane structures. The presence of a branched siloxane structure results in hardness and low insulating properties, while a linear siloxane structure yields softness and highly insulating properties. Both types of epoxy-based siloxane/silica composites exhibit high thermal stability and low thermal expansion. These properties are considerably improved by incorporating silica particles. We expect that our developed epoxy-based composites to hold significant potential as advanced electronic packaging materials, offering high-performance and robustness.

Smart retail enabled through in-store technology (IST) is believed to be the future of retail. However, several IST impacts, especially on individuals' well-being remain undisclosed. This study attempts to discover IST impact, particularly electronic shelf label (ESL) as a prospective technology, on customer well-being and post-transaction behavior (i.e., willingness to pay (WTP) and positive word of mouth (PWOM). Survey were from generations X, Y, and Z generating 305 respondents. A post hoc analysis utilizing PLS MGA is discussed for Gen X & Millennials vs. Gen Z groups. This study provides empirical evidence of smart retail on customer well-being and how it affects customer post-purchase behavior, namely WTP and PWOM. This study also provides evidence of how it differs across generational cohorts.

Single-walled carbon nanotube (SWNT) has gained significant interest as a transducer in various electrochemical sensing devices due to their unique structure, compatibility with biomolecules, and excellent electronic properties. As-prepared SWNTs are usually a mixture of semiconducting and metallic ones. Despite of the higher content of semiconducting components in mixed SWNTs, metallic properties are predominantly expressed due to the bundling issue of the SWNT during the fabrication process, limiting the applicability to bio-transistor application. Here, we present a multi-scale semiconducting electronic film of SWNTs as a transducing platform for electrochemical field-effect-transistor (eFET) suitable for the sensitive detection of subtle biological modulation. A genetically engineered filamentous M13 phage showing strong binding affinity toward SWNTs on its body surface was used as a biological material, allowing us to fabricate a large-scale transparent semiconducting nanocomposite. As the relative ratio of SWNT to M13 phage decreases, the on–off ratio of SWNT electronic film increases by 1200%. To show broad applicability, the multi-scale SWNT nanomesh-based eFET is applied for monitoring a variety of biological reactions in association with enzymes, aptamers, and even cyanobacteria. The biomimetic electronic material system with the capability of transducing biological responses at a large scale over a broad dynamic range holds excellent promise for biosensors, biofuel cells, and environment monitoring.

비대면 교육 플랫폼의 필요성은 COVID-19 팬데믹으로 가속을 받게 되었다. 코로나 바이러스의 확산을 막기 위하여 대한민국의 대다수 교육기관들은 등 하교를 최소화 하였으며, 수업 방식은 네트워크를 이용한 화상 회 의 형태로 변하게 되었다. 화상 회의 형태의 비 대면 교육 플랫폼은 교수자 및 학생들에게 정적인 상호작용 (Static Interaction)만을 지원하여 학생들의 적극적인 수업 참여를 유도 하지 못했으며, 교수자의 교육 방식에 큰 제한을 주어 수업의 질을 크게 낮추게 되었다. 본 논문에서는 학생들의 자율적인 수업 참여율을 높이기 위 하여 게임의 특성을 가지는 메타버스 형태의 Web 기반 비 대면 교육 플랫폼”Off-On Class”를 제안한다. ”Off-On Class”는 강남 수학의 힘 학원에서 비 대면 교육 플랫폼의 요구 사항을 분석하여 개발 및 시범 운영 을 하였다.

In this study, we performed thermal safety design of the electric module of a heat-loaded equipment with consideration of its heat dissipation performance. Initially, we calculated the heat dissipation of natural convection to choose a cooling method. Based on this, we found that some modules required forced convection and selected an air-cooling method with an outdoor temperature of 43 degrees Celsius, which is the maximum temperature in Korea. Prior to module production, we performed thermal analysis of each module and proceeded with a design to increase the thermal conductivity of the module as a primary step, and subsequently proceeded with Heat Sink design to maximize the heat dissipation performance. After considering various constraints according to the system requirements and designing the cooling path, we experimentally and analytically secured thermal safety at the operating temperature of the equipment.

이 연구는 사회적 낙인과 전자감독과의 관계를 실증적으로 테스트해보고자 하였다. 특히 사회적 낙인으로 인해 전자감독제도가 전자감독 대상자들에게 얼마나 사회경제 적인 지위에 손상을 입혔는지, 현재 직장생활을 하고 있는 전자감독 대상자들의 사회 적 낙인과 어떠한 관련성을 맺고 있는지 살펴보는데 목적을 두고 있다. 전자감독제도의 목적이 전자감독을 통한 재범 예방에 있기 때문에 예방적인 측면에서 살펴볼 필요가 있는 것이 사실이지만, 실제로 전자감독 제도가 사회적 “낙인”과 맺는 관계에 대해서는 제대로 다루어지지 않고 있다. 따라서 이 연구는 OLS 위계적 회귀분석을 활용하여 전자감독 대상자 중 현재 직장 생활을 하고 있는 대상자를 중점으로 직장 내 지위 박탈이 전자장치 훼손 충동성에 유의 미한 영향을 미치는지 검증하였다. 연구 결과, 사회적 낙인이 다른 변수를 통제할 때, 전자감독 대상자가 전자장치를 훼 손시키려는 의지에 통계적으로 유의미한 영향을 미치는 것으로 나타났다. 즉, 전자감독 대상자가 사회적 낙인으로 인해 직장생활 및 사회생활을 제대로 할 수 없게 되면 전자장 치 훼손 충동을 느끼게 될 가능성이 큰 것으로 볼 수 있다. 따라서 향후 사회적 낙인과 관련된 범죄자 주변 환경의 불합리한 직장 내 편견을 해소할 수 있는 세심한 보호관찰 전략이 만들어질 필요가 있다고 하겠다.
