<P>Platinum-based metal alloys have been generally developed to provide high carbon monoxide resistance in the anodes of direct methanol fuel cells. We report the potential of bimetallic platinum/iridium electrocatalysts in preserving the outstanding carbon monoxide tolerance obtained from both experimental and theoretical studies, which represents the enhanced electrochemical performance of methanol oxidation and the in-depth and stepwise investigations for reaction mechanisms, respectively. In this study, the findings highlight the dual-enhancement characteristics of low carbon monoxide adsorption energy (electronic effect) and carbon monoxide oxidative removal (bifunctional effect) compared with various electrocatalysts such as platinum, iridium, and platinum/ruthenium alloys. In addition, the reaction affinity of platinum/iridium alloys for methanol dehydrogenation is also studied in accordance with atomistic properties, such as adsorption energy and electronic band gap, to understand the electrochemical performance compared to Pt. The results obtained indicate that the platinum/iridium alloy surface played diverse roles in terms of its multifunctional behaviors for carbon monoxide tolerance, including the favorable mechanism of methanol dehydrogenation. It turns out that throughout the theoretical in-depth studies, platinum/iridium alloys are promising candidates in terms of the extension for electrocatalytic material designs that differ from Ru in direct methanol fuel cells.</P> [FIG OMISSION]</BR>

Yongju Kwon(권용주),Hyuna Bak(박현아),Cheonglim Lee(이청림),Youjae Yi(이유재) 한국경영학회 2022 經營學硏究 Vol.51 No.1

The current research proposes a restructured model of the Korean representative measurement of service quality, KS-SQI 3.0. As social values have become an important theme for corporate sustainability in management, companies are being asked to fulfill their social responsibilities and corporate citizenship. In addition, service quality is an essential factor for the success of companies not only in service industries but also in manufacturing industries. KS-SQI 3.0 reflects these issues and consists of four quality dimensions: service outcome quality, service interaction quality, service environment quality, and social quality. By analyzing responses from customers of convenience stores(N=900) and mobile communication services(N=900), the present research tests the reliability and validity of KS-SQI 3.0 and causal relationships between service quality and its consequences. The results of confirmatory factor analysis revealed that the structure of service quality composed of four dimensions with eight sub-dimensions is satisfactory in terms of goodness-of-fit and reliability. Tests for causality by structural equation modeling indicate that service quality affects overall service quality and subsequently customer satisfaction, which, in turn, influences customer loyalty and happiness. The current research provides theoretical and managerial insights and directions for future research on applications of KS-SQI 3.0.

권용주(Yongju Kwon),이무용(Mooyong Rhee),김지영(Jeeyoung Kim),권광일(Kwangil Kwon),김소진(Sojin Kim),신희준(Heejun Shin),박성수(Seongsoo Park),이은주(Eunju Lee),박혜경(Hyekyung Park),박용순(Yongsoon Park) 한국식품영양과학회 2010 한국식품영양과학회지 Vol.39 No.4

나트륨의 과잉섭취가 고혈압의 주요한 위험요인으로 알려져 있는데, 한국인의 성인 하루 평균 소금 섭취량은 영양섭취기준보다 3배 이상 높다. 본 연구에서는 식품교환표를 이용하여 14일간의 식단을 작성하고 조리된 음식의 나트륨 함량을 실제로 측정한 후 식품교환표와 식품성분표에서 계산된 나트륨 추정치와 비교하여, 각각 방법의 정확성 및 문제점을 파악하고자 하였다. 그 결과를 요약하면 아래와 같다. 하루 식단의 나트륨 함량에서 식품교환표로 계산한 추정치는 실측치와 유의한 차이가 났으나, 식품성분표는 실측치와 유사하였다. 음식별 절대값의 비교에서는 식품교환표로 계산한 나트륨 추정치와 식품성분표로 계산한 나트륨 추정치가 모두 실측치와 유의한 차이가 났다. 음식군별 절대값 비교에서는 양념류의 나트륨 함량이 많은 주요리, 부식, 국물요리에서 상당히 유의한 차이가 났으며, 식품교환표로 계산한 추정치, 식품성분표로 계산한 추정치, 실측치간의 차이가 큰 음식들이 모두 주요리, 부식, 국물요리였다. 이상의 결과에 따르면, 단순히 하루 식단의 나트륨 함량 비교에서 식품교환표에 비해 식품성분표의 나트륨 함량이 더 정확하다고 생각할 수 있지만, 음식별 또는 음식군별로 추정치와 실측치간의 차이를 절대값으로 비교한 결과, 식품교환표와 식품성분표의 나트륨 함량 모두 실측치와 차이가 컸다. 특히 나트륨 과잉 섭취의 주요 원인으로 보고되는 양념류의 차이로 장류, 김치 등의 사용이 많은 한국음식에서 식품교환표와 식품성분표를 이용한 추정치와 실측치의 차이가 컸다. 따라서 고혈압 및 신장질환 환자를 위한 저염식단작성시 식품교환표나 식품성분표를 사용할 때 실제 소금량과의 차이를 고려해야한다. Excessive intake of sodium is known as a risk factor for hypertension, and Korean adults consume sodium 3 times higher than Dietary Reference Intakes (DRIs). The purpose of this study was to evaluate the difference on sodium content between analyzed and estimated by food composition table and food exchange list. Seven days of low salt diet and seven days of high salt diet were prepared, and sodium contents were estimated by food composition table and food exchange list and measured by atomic absorption spectrophotometer. Sodium contents of diet per day estimated by food exchange list significantly differed from analyzed content, but those estimated by food composition table were not. However, when absolute differences from analyzed content were compared by dishes in the low and high salt diet periods, there were significant differences among estimated sodium content by food composition table and food exchange list and analyzed sodium content. The discrepancy between those results was due to that absolute value was used to compare sodium contents of dishes but not to compare sodium contents of days. In addition, main dish, side dish, and soup were significantly different among estimated sodium content by food composition table and food exchange list and analyzed sodium content. Actual sodium contents of Jap-Chae Deop-Bap and Roasted chicken with oyster sauce differed to a great extent from estimated contents by food exchange list and food composition table. In conclusion, actual sodium contents of Korean dishes were significantly different from those estimated by food composition table and food exchange list, and thus these differences in salt content should be considered on planning of low-salt menu for hypertensive patients.

혜택 지향 vs. 수익 지향: 공유경제 플랫폼 서비스 프레이밍이 기업 탐욕에 대한 인식과 서비스 이용 의도에 미치는 효과

권용주(Kwon, Yongju),이신형(Lee, Shinhyoung) 한국마케팅학회 2021 마케팅연구 Vol.36 No.4

최근 학계의 논의에서는 공유경제 플랫폼을 협력의 가치를 지닌 지속 가능한 경제 체제로 보는 긍정적인 시각과 플랫폼 자본주의로 간주하는 부정적인 시각이 공존한다. 이러한 상반된 견해를 고려할 때, 소비자들 역시 공유경제 플랫폼 서비스를 어떻게 해석하는가에 따라서 공유경제 플랫폼 기업에 대한 인식과 서비스 이용 의도가 달라질 수 있다. 본 연구는 공유경제 플랫폼 서비스의 프레이밍(혜택 지향 vs. 수익 지향)이 소비자들의 서비스 이용의도에 미치는 영향의 심리적 기제를 밝히고, 소비자들의 기질적 특성인 프로테스탄트 직업윤리에 따라서 조절되는 효과를 검증하고자 진행되었다. 연구 1은 대표적인 P2P 공유경제 플랫폼인 에어비앤비 서비스가 혜택 지향(vs. 수익 지향)으로 프레이밍되었을 경우, 에어비앤비의 탐욕에 대한 인식을 낮춤으로써, 기업의 평판과 서비스 이용 의도를 연쇄적으로 상승시키는 직렬매개효과를 검증하였다. 또한, 서비스 프레이밍이 기업 평판 및 서비스 이용 의도에 미치는 효과에 대한 대안적인 심리적 기제를 실증적으로 제거하였다. 연구 2는 에어비앤비 서비스 프레이밍이 서비스 이용 의도에 미치는 효과가 소비자 개개인의 프로테스탄트 직업윤리에 따라 조절되는 효과를 검증하였다. 구체적으로, 프로테스탄트 직업윤리가 높은 사람들은 에어비앤비 서비스가 혜택 지향(vs. 수익 지향)으로 프레이밍되었을 경우에 더 높은 이용 의도를 보였으나, 프로테스탄트 직업윤리가 낮은 사람들은 에어비앤비 서비스가 수익 지향(vs. 혜택 지향)으로 프레이밍되었을 때 상대적으로 더 높은 서비스 이용 의도를 보였다. 또한, 프로테스탄트 직업윤리의 조절효과는 인구통계학적 변수와 에어비앤비에 대한 인식 및 경험과 관련된 변수들의 효과를 통제하였을 경우에도 통계적으로 유의한 결과를 보였다. 이러한 연구 결과를 바탕으로 이론적·실무적 시사점을 논의하고, 향후 연구 방향성을 제시하였다. In recent academic discussions, there coexist a positive view of sharing economy platforms as a sustainable economic system with the value of cooperation and a negative view of it as a platform capitalism. Given these conflicting academic views, consumer perceptions and willingness to use the services may vary depending on how consumers interpret the services of sharing economy platforms. The present research aimed to test psychological mechanisms of the framing effect of platform services on willingness to use the services and the moderating role of Protestant work ethic in this relationship. In Study 1, we found a serial mediation effect that when Airbnb, a representative P2P sharing economy platform, was framed as a service for benefit (vs. for profit), participants perceived less corporate greed, enhancing corporate reputation and willingness to use the service in turn. We also ruled out an alternative psychological mechanism. In Study 2, we also showed that the service framing effect was moderated by individual levels of Protestant work ethic (PWE). Specifically, people with high PWE indicated higher willingness to use Airbnb when the service was framed as one for benefit than one for profit. However, people with low PWE showed the opposite pattern, indicating higher willingness to use Airbnb when the service was framed as one for profit than one for benefit. This moderating role of PWE in the service framing effect was sustained even when the effects of demographic characteristics as well as perceptions and experiences related Airbnb were controlled for. Based on findings, we discussed theoretical and practical implications and proposed the directions for future research.
