Internal replaceable electronic module substitutions can impact EMC (ElectroMagnetic Compatibility) qualification testing and results if EMC testing is conducted at the cabinet level. The impact of component substitutions on EMC qualification results therefore should be evaluated. If a qualitative evaluation is not adequate to ensure that the modified product will not impact the cabinet level EMC qualification results, a new qualification testing should be conducted. Component level retesting should be conducted under electromagnetically equivalent conditions with the cabinet level test. This paper analyzes the propagation of conducted susceptibility test waveforms in a representative cabinet and evaluates the impact of component substitutions on cabinet level EMC qualification results according to the location of the replacement items. A guideline for a qualitative evaluation of the impact of component substitutions is described based on the propagation of the conducted susceptibility test waveforms. A module level test method is also described based on an analysis of the shielding effectiveness of the cabinet.

This paper addresses the central issue of whether it is effective for a firm to discourage the purchase of its own product in order to support a social cause. The objectives of this study were: a) to examine whether a cause-related self-prevention ad would stimulate more positive evaluations compared to promotional ad, particularly when the product category is more negatively socially accepted; and 2) to determine if a negative attitude toward the product could induce a boomerang effect of a selfprevention ad. Results from three experiments revealed that socially responsible prevention campaigns against firm's own product may be more effective for the product category negatively associated with social concerns or welfare. If products are more limited in the social context, communications of product prevention are beneficial to improve the public image of the brand. However, the self-hurting approach may be inappropriate for potential customers who currently possess a strong negative attitude toward the product.

원자력발전소는 냉각재상실사고(LOCA)와 같은 과도상태시 pH 조절을 통해 격납건물의 핵분열생성물(요오드) 제거 능력을 유지한다. 이와 더불어 격납건물 내부의 스테인레스강 기기들의 응력부식균열(Stress Corrosion Cracking)을 방지하고 알루미늄 또는 아연 부식에 의한 수소생성을 최소화할 수 있기 때문에 살수 및 집수조냉각수의 화학조건(pH) 조절능력이 요구된다. 현재 원전은 LOCA시 능동형 살수첨가제인 NaOH를 사용하여 격납건물 살수 및 집수조냉각수의 pH를 조절하도록 설계되어있다. 본 논문에서는 LOCA시 집수조냉각수의 pH를 분석하고, 살수화학조건 pH 관련 최신규제요건인 표준심사지침(SRP) 6.5.2에 따라 핵분열생성물제거상수 및 제염계수를 계산하였다. 분석결과, 격납건물집수조 pH는 8.09~9.67로서 설계기준을 만족한다. 그리고 격납건물살수계통에 의한 핵분열생성물 제거상수 및 제염계수는 원전 내환경기기검증을 위한 방사선환경 평가의 입력으로 제공된다.

홍삼으로부터 홍삼알콜 추출물을 제조하고 부산물로 생성된 홍삼추출잔사로부터 한외 여과를 이용하여 홍삼산성다당체(RGAP, red ginseng acidic polysaccharide)를 대량으로 분리할 수 있는 방법을 개발하였다. 본 방법으로 홍삼추출잔사로부터 분리된 RGAP의 수율은 20.9%이었고, RGAP로부터 지표성분인 활성성분(GFP)의 분리수율은 39.4%이었다. 분리된 RGAP는 macrophage에 의한 NO(nitric oxide)를 생성하여 암세포를 사멸시키는 것으로 나타났다. RGAP를 BALB/c 마우스에 복강투여한 후 분리된 복강 macrophage를 P815 암세포(mastocytoma)와 함께 배양하였을 때 배지내의 NO 농도는 대조군에서 4.3 $\mu\textrm{m}$이었으나, RGAP 100, 300 mg/kg 투여군에서는 각각 9.8 및 25.3$\mu\textrm{m}$로 증가하는 경향을 나타내었다. 아울러 암세포인 P8l5세포의 사멸율도 정상대조군일 경우 7.3%이었으나 RGAP 100, 300 mg/kg 투여군에서는 각각 22.7 및 31.8%로 증가하는 경향을 나타내었다. RGAP을 2M의 TFA로 10$0^{\circ}C$에서 1시간 가수분해한 후 당 표준품과 TLC로 비교한 결과 당 표준품과 Rf치 및 발색 색깔이 일치하는 4개의 spot, 즉 rhamnose(Rf 0.78, 노란색 ), glucose(Rf 0.61, 녹색), galactose(Rf 0.56, 녹색), glucuronic acid(Rf 0.36, 황갈색)를 관찰할 수 있었다. 가수분해된 RGAP 분해산물을 Gl(glucose)부터 G7(maltoheptaose)까지의 당류와 함께 TLC를 행한 결과 진한 색상을 나타내는 spot은 Rf 0.56~0.61로 G2(maltose, Rf 0.46) 이상의 단당류(monosaccharide)인 것으로 나타났다. RGAP의 일부 이화학적 특성을 조사한 결과 pH는 4.74, 건조감량은 4.72%, 조단백질 함량은 3.30%, 회분은 4.74%이었고 중금속인 Pb는 2.30 ppm이었다.

고도로 발달되고 있는 산업 사회에서의 디자인의 의미는 기업경영전략의 핵심이며 나아가 국가 경쟁력을 결정짓는 중요한 이슈이며 지속적인 경쟁우위를 획득하기 위한 수단이 되고 있다. 그리고 이러한 현상은 제품의 기술적 기능보다는 제품의 심미성이 제품 디자인에 중요한 특성이 되고 있다는 사실을 말해주고 있다. 본 연구에서는 사용자의 제품선호도와 제품 평가에 영향을 주는 심미적 영향요소를 규명하기 위해 심미적 영향요소에 관한 선행연구를 토대로, 8가지의 심미적 영향요소를 선정하였다. 선정된 8개의 심미적 영향요소인 단순/복잡(simplicity), 균형(balance), 통일(unity), 율동(rhythm), 시대성/스타일(style), 독특성(novelty), 전형성(typicality), 비례(proportion)를 가지고 사용자 선호와 제품평가에 영향을 주는 심미적영향요소를 파악하였다. 따라서 본 연구에서는 제품별로 사용자 선호에 중요한 영향을 미치는 심미적영향요소의 중요도 정도와 고려해야 할 요소를 밝혀 제품디자인에 있어 심미적 영향요소의 가이드라인을 제시하여 제품디자인 시 활용할 수 있는 자료를 제공하고자 하였다.

Pyrrosia lingua has been widely used as a traditional medicine for the treatment of lots of diseases including pain management. However pharmacological and phytochemical studies on its anti-nociceptive properties are extremely limited. In this work, we investigated the effects of methanol extract of Pyrrosia lingua (MPL, 250 and 500 mg/kg) on the both of central and peripheral nociceptive pain. The results from tail-immersion test and hotplate test revealed that MPL has potent anti-nociceptive effects on thermal nociception. In addition, MPL efficiently reduced the acetic acid-induced chemical nociception compared to indomethacin. We also carried out formalin test and MPL reduced formalin-induced pain response on both phases, suggesting MPL has antinociceptive activities on the central and peripheral pain. In combination test using naloxone, anti-nocicpetive activity of MPL was reduced, indicating that MPL acts as a partial opioid receptor agonist. These results suggest that MPL may be possibly used as a valuable natural product-derived painkiller.

The study attempts to investigate the causes of Sino-U.S. trade friction in recent years and provides countermeasures accordingly. The import and export volume of two countries, the product structure of China's export, the 337th Act lawsuits related to China, the industries involved in trade friction, and the G-L Index of Sino-U.S. Products are analyzed in detail. The causes of Sino-US trade frictions are discussed from the aspect of mercantilism and trade protectionism, interest groups and governments' trade policies, Chinese product structure, intellectual property protection in China, and performance of Chinese enterprises in litigation. Based on these, countermeasures are put forward. China needs to implement industrial upgrading, increasing the added value of products, and improving intellectual property protection. A trade friction warning system also needs to be constructed. The Chinese government needs to carry out strategic dialogue and international negotiation.

Purpose: This study investigates how the salespersons behave in coordinating the multiple communication channels during supplier integration (SI) for new product development (NPD), especially when their engineers directly collaborate with the buyer. Methods: This study conducted a qualitative study to explore the dynamics of the supplier's salespersons during SI for NPD. With the support of a consumer goods manufacturer (focal firm) in South Korea, we interviewed several managers, including purchasing and engineering, from the focal firm and salespersons from eight tier-1 suppliers of the focal firm. Results: The results found that the supplier's salespersons show two different behaviors toward managing and controlling the collaboration between their engineers and the buyer: (1) Process regulating behaviors that control the flows of information or communication between the engineers and the buyer, and (2) knowledge regulating behaviors that directly and indirectly support the engineers to be equipped with accurate and complete knowledge so that they can share the right knowledge with the buyer. Conclusion: This study contributes to academia and practitioners as follows. To academia, this study fill the gap in the literature by introducing the distinct behaviors of the supplier's salesperson in SI for NPD. To practitioner, in addition, our findings present coordination mechanisms to manage and control multiple communications within an inter-organizational collaboration.
