'Live + Sale' is actively promoted in China and 'Wang-Hong', also known as Chinese internet celebrities are dominating this format of marketing strategy recently. They introduce products to consumers through live broadcasts, promote online shopping, and frequently evoke impulsive buying. Under this context, it is worth focusing on what factors influence impulse buying during Wang-Hong's live broadcast. This study investigated the impact of Wang-Hong characteristics on impulse buying behavior when watching live sales. Also, the mediating role of flow experience and viewing satisfaction was explored. Furthermore, we expected that the different live broadcast circumstances could have a different impact on flow experience, viewing satisfaction, and impulse purchase. A total of 242 Chinese women who have experience of viewing live sales were recruited through a Chinese research platform. The results revealed that Wang-Hong's trustworthiness and attractiveness positively affected the viewer's impulse buying directly, and indirectly through flow experience and viewing satisfaction, whereas expertise did not have any impact on impulse purchase. However, there were no significant differences between the two live broadcast circumstances. This research can enhance understanding of the impulse buying process during Wang-Hong's live sale and help brands come up with effective influencer marketing strategies using live sales.

TVarious studies in different industries have proven the effectiveness of nanotechnology, which is considered as a representative technology that makes lives faster and more convenient and economical. However, as nanomaterials are tiny, consumers are concerned on whether they can do any physical harm. Therefore, based on the perceived usefulness and ease of use from the generally used Technology Acceptance Model (TAM), this study added additional variables including perceived risk. Moreover, this study introduced three kinds of trust (institution, people, and technology trust) as moderating variables, which can reduce the negative effect of perceived risk. Based on the analysis using the Structural Equation Model, we determined that perceived usefulness and ease of use positively influenced the intention to adopt nanotechnology products. Thus, when consumers regarded nanotechnology products as efficient and convenient, they showed increased intention to adopt the technology. Furthermore, perceived risk negatively affected the intention to adopt nanotechnology products, that is, when customers' perceived risk increased, the adoption intention of nanotechnology product decreases because of the potential risk from nanotechnology. On the one hand, the negative effect of perceived risk on adoption intention decreased when trust in nanotechnology washigh and when consumers highlytrust experts or administrators. On the other hand, trust in government, public institutions, and companies which produce nanotechnology products showed no significant moderating effect. This study is meaningful as it generalized TAM by applying the model to new nanotechnology products and extended existing studies by the addition of perceived risk and various trust factors to the model.

Biopharmaceuticals and the cell substrates used for their manufacture are currently tested for porcine adventitious viruses due to the widespread use of porcine trypsin in cell culture. Porcine transmissible gastroenteritis virus (PTGV) is one of the major adventitious porcine viruses causing contaminated during the manufacture of biopharmaceuticals. Therefore, rapid and sensitive detection of PTGV is essential in ensuring the safety of biopharmaceuticals. A TaqMan probe real-time RT-PCR method was developed for the quantitative detection of PTGV contamination in cell substrates, raw materials, manufacturing processes, and final products, as well as PTGV clearance validation. Specific primers for the amplification of PTGV RNA were selected, and PTGV RNA was quantified by use of a specific TaqMan probe. Specificity, limit of detection (LOD), and robustness of the method was validated according to international guidelines on the validation of nucleic acid amplification tests. The sensitivity of the assay was calculated to be 1.10 × 10⁰ TCID₅₀/ml. The real-time RT-PCR method was validated to be reproducible, very specific to PTGV, and robust. The established real-time RT-PCR assay was successfully applied to the validation of Chinese Hamster Ovary (CHO)-K1 cells artificially infected with PTGV.

메모리 반도체 세계 시장 점유율 1위 뿐만 아니라 국내 전체 산업 가운데 가장 중추적인 역할을 하는 반도체 산업의 지속적인 성장과 국가 경제의 발전을 위해서 소자 업체 뿐만 아니라 장비, 소재, 부품 산업의 동반 성장은 반드시 필요하다. 그 중에서 특히 소재, 부품 산업을 발전시키는 것이 국산 반도체 장비의 시장 점유율이 낮은 현 시점에서 가장 필요한 선택이다. 반도체 소재, 부품 산업의 발전을 위해서 제일 먼저 해야할 일은 영세한 국내 반도체 소재, 부품 산업을 활성화 시키는 것이며, 지속 적인 연구 개발, 성능 평가 방안 확보, 수요 업체와의 연계 방안 확보 등이 주요 현안이다. 반도체 소자 업체, 장비 업체에서 원하는 소재 및 부품의 성능을 만족하는 제품을 만들기 위해서는 우선 소재 및 부품의 기본 특성을 만족하는지에 대한 평가가 필요하고, 더 나아가서는 디바이스의 특성을 만족시켜줄 수 있는 한 단계 상향된 수요자의 요구 조건을 만족 시켜줄 수 있어야 한다. 본 연구에서는 그 중 특히 중요한 요소인 성능 평가에 대해서 논하고자 한다. 우선 반도체 공정용 소재에 대해서 살펴 보면 대표적인 반도체 소재로 증착용 Precursor, Photo Resistor, Sputter Target 등이 있다, 평가 방법으로는 ALD용 Precursor의 경우 대기 노출시 폭발, 화염 발생 등의 위험 요소를 안고 있어 특별한 주의가 요구 된다. PR이나 Sputter Target은 상대적으로 위험성은 적으며, 다양한 성능 평가 들이 가능하다. 다음으로 부품 평가에 대해서 살펴 보자. 본 원에서 가장 많이 진행된 부품 평가는 개발된 Pump의 성능 평가이다. 개발된 Pump는 1차적으로 KRISS 진공센터 에서 기본 Pumping 능력 평가를 실시하고, 다음으로 공정 평가를 실시한다. Pump마다 특성이 달라서 각 펌프의 성능 평가에 적합한 공정과 장비를 우선 선정하고 그에 합당한 공정을 진행하여 평가를 실시한다. 고 진공용인 Cryo Pump는 순수한 물질의 증착이 중요한 Metal Sputter 공정 장비에 장착하여 공정용 Gas를 흘리면서 Pump의 구동에 따른 성능 평가를 하고, 다음으로 실제로 Metal Sputter를 실시해서 Wafer에 증착된 물질의 특성을 확인한다. 다음으로 Turbo Pump의 경우 Etch 장비에 장착하여 Etch Uniformity, Etch Rate, By-product 배출 정도에 대해서 평가를 한다. Dry Pump는 비교적 공정 압력이 낮은 PECVD 공정 장비에서 평가를 진행 한다. 마지막으로 공정 진단, 챔버 상태 진단 등을 할 수 있는 별도의 부품 또는 장치로 PBMS, PCDS, OES 등의 평가에 대해서 논한다. 본 장치들은 실제 반도체 공정 장비와 환경에서 평가가 되어야지만 최종 사용자 입장에서 신뢰를 가지고 결과에 대해서 접근할 수 있다. 위에 논의된 장치들은 현재 공정 장비에 부착되어서 판매 되고 있는 것이 아니라 수요가 많지 않으나, 자체 성능 개선과 적합한 평가를 통해서 장치의 성능이 인정되면 300 mm 이상 Wafer 공정에서 반드시 필요한 실시가 공정 진단을 위해서 폭발적인 수요를 창출할 수 있으리라 본다.

The great variety of commercial brands of orthodontic wires available on the market, stimulated by the so called superior wires (nickel titanium with shape memory effect and superelastic nickel titanium), makes the professional choice for a suitable and less expensive material difficult. The in vitro study of the mechanical properties of the orthodontic wires acts as an auxiliary tool for the professional. In this paper, a comparative study of mechanical properties was made, using stress strain tests for 4 types of orthodontic wires (conventional stainless steel, multistranded steel, superelastic nickel titanium and thermoactivated nickel titanium) separated into 5 groups. A series of 6 tests were tested for each group of wires. Initially, each group was tested 3 times until the wires broke. Furthermore, 3 more tests for each group were performed, stretching the wires under standardized activation loads, for a reliable comparison of their mechanical properties, during loading and unloading. 1 tests were applied to check differences among the groups. In vitro, the results suggest that regarding the mechanical properties supposedly desirable for physiological teeth movement, such as resilience, elasticity modulus, strength liberated during unloading, and the way that strength is liberated, thermoactivated nickel titanium wires, acting under mouth temperature, seems to be a good choice, fellowed by superelastic nickel titanium, multistranded stainless steel, and conventional stainless sleet. Superelasticity was demonstrated for superelastic nickel titanium wires. When at $37^{\circ}C$, thermoactivated nickel titanium wires showed shape memory effect, showing that temperature is important for enhancing the mechanical properties.

Bovine blood, cell, tissue, and organ are used as raw materials for manufacturing biologics such as biopharmaceuticals, tissue-engineered products, and cell therapy. Manufacturing processes for the biologics have the risk of viral contamination. Therefore viral validation is essential in ensuring the safety of the products. Bovine parvovirus (BPV) is one of the common bovine pathogens and has widely been known as a possible contaminant of biologics. In order to establish the validation system for the BPV safety of biologics, a real-time PCR method was developed for quantitative detection of BPV contamination in raw materials, manufacturing processes, and final products. Specific primers for amplification of BPV DNA were selected, and BPV DNA was quantified by use of SYBR Green 1. The sensitivity of the assay was calculated to be $1.3{\times}10^{-1}\;TCID_{50}/mL$. The real-time PCR method was validated to be reproducible and very specific to BPV. The established real-time PCR assay was successfully applied to the validation of Chinese hamster ovary (CHO) cell artificially infected with BPV. BPV DNA could be quantified in CHO cell as well as culture supernatant. Also the real-time PCR assay could detect $1.3{\times}10^0\;TCID_{50}/mL$ of BPV artificially contaminated in bovine collagen. The overall results indicated that this rapid, specific, sensitive, and robust assay can be reliably used for quantitative detection of BPV contamination during manufacture of biologics.
