분산 환경에서 여러 호스트들간의 자료를 공유하는 것은 네트워크에 부하를 줄이고 가용도를 높일 수 있지만 복제된 공유 자료들의 일치성을 유지하는 것이 필요하다. 전통적으로 분산된 공유자료의 일치성을 위해서 무효화방식(invalidate protocol), 갱신방식(update protocol) 그리고 이주방식(migratory protocol)등이 사용되었다. 분산 환경뿐만 아니라 이동컴퓨팅 환경에서도 분산된 호스트들간에 공유자료의 일치성을 유지하기 위해서 적절한 프로토콜을 선택하는 것은 중요하다. 본 논문에서는 이동 컴퓨팅 환경에 효과적으로 적용 할 수 있는 공유자료의 일치성 유지하기 위한 프로토콜을 제안하고 성능 분석을 하였다.

Two experiments were conducted to explore the implicit representation of gender-stereotype using primed naming task for prime-target pairs. In Experiment 1, Participants were presented gender's attributes as primes at SOA 250ms and were asked to pronounce person's names which differed in typicality and preference of gender's attributes. The results showed that gender congruent effects was not found, but typicality effects and interactions were found. In Experiment 2, Participants were presented gender's attributes as primes at SOA 250ms and were asked to pronounce gender's attributes which differed in typicality of gender's attributes. The results showed that woman's attributes superiority effects were found, but typicality effects were not. These results were discussed from a point of view of graded representation of gender stereotype and asymmetrical processing of gender stereotype to priming conditions in the implicit level.

이 연구는 선거에서 후보자들의 정책 입장(issue stance)을 유권자들이 어떻게 판단하고 인식하는 지 살펴본다. 기존의 연구들은 후보자들의 정책에 대한 유권자들의 인식을 설명하는 데서 캠페인 정보(campaign information)의 직접적인 영향을 제대로 고려하지 않았다. 이 논문은 후보자 정책 입장에 대한 캠페인 정보가 과연 유권자들의 인식에 직접적인 영향을 미치는 지 미국에서 이루어진 실험 데이터를 이용하여 분석한다. 아울러 투영 효과(projection effect)나 허구적 일치성 효과(false consensus effect) 등 기존의 연구에서 제시된 설명들이 이러한 캠페인 정보의 영향을 감안했을 경우에도 여전히 유효한 지 살펴본다. 실험 데이터의 분석 결과는 캠페인 정보가 후보자 정책에 대한 유권자들의 판단에 직접적인 영향을 미치며, 이러한 캠페인 정보의 영향을 감안했을 때 투영 효과는 여전히 유효한 반면 허구적 일치성 효과는 상대적으로 약하게 나타난다는 것을 보여준다.

공간서비스 그룹을 구성하는 업체들이 공간이라는 서비스를 제공하면서 사용자의 이용목적과 생애주기에 맞춘 용도로 그 사업모델을 구축하고 있다. 이와 같이 공간대여 서비스는 효율적이고 생산적인 학습효과를 제공하며, 스터디 센터와 스마트 워크에 초점을 많은 업체들이 등장하고 있는 실정이다. 하지만 공간대여 서비스와 소비자의 일치성에 관한 연구가 부족한 실정이다. 따라서 본 연구는 공간대여 서비스에 대한 개념을 분석하여 공간에 대한 접근성, 내부환경요인, 서비스 내의 시설이 시설 만족도에 미치는 영향과 소비자의 자아이미지 일치성, 기능적 일치성, 가치 일치성이 고객만족에 미치는 영향을 분석하였으며, 마지막으로 시설만족도와 고객만족이 이용공간에 대한 애호도에 미치는 영향을 살펴보았다. 공간대여 서비스의 구성요소인 접근성, 내부환경요인, 서비스내의 시설과 시설 만족도와의 인과관계에 대한 실증 연구결과를 요약하면 접근성과 서비스내의 시설은 시설만족도에 유의적인 영향을 미치는 것으로 나타났지만 내부환경요인은 시설만족도에 유의적인 영향을 미치지 않는 것으로 나타났다.

We investigated the role of product-influencer congruence between social distance, perceived authenticity and attitude toward ads. In particular, we focused on the mediating effect of perceived authenticity on the relationship between social distance and attitude toward ads. Also, we interested in the conditional indirect effect of product-influencer congruence on the mediation process. For our purposes, data were collected from a convenience sample of 340 undergraduate students at a large university in South Korea. Our results indicated that social distance is directly related to the perceived authenticity and, consequently, affects attitude toward ads. Also, an indirect effect of the perceived authenticity was significant on the low level of product-influencer congruence and not in the high level. Our findings suggest that marketing managers should consider the social media influencer's authenticity and congruence between the product and the influencer.

This study was conducted to explore whether an automatic evaluation effect (i.e.,congruency effect and positive priming effect) of emotional properties which have been found in the racial prejudice study can be applied to the gender properties. Experiment 1 employing a short SOA (150ms-250ms) naming task showed a priming effect was larger in the positive prime-positive target condition than negative prime-negative target condition but not congruent effect. Experiment 2 employing a long SOA (500ms-1000ms) naming task didn't yield either positive priming effect or congruency effect. The congruency effect and the positive priming effect which is ubiquitous phenomenon in the generic cognitive concepts network were not found in the gender properties. Therefore, it was suggested that the social information including prejudice or stereotype can be differently processed according to the value of emotionality.

This study was conducted to explore whether an automatic evaluation effect (i.e.,congruency effect and positive priming effect) of emotional properties which have been found in the racial prejudice study can be applied to the gender properties. Experiment 1 employing a short SOA (150ms­250ms) naming task showed a priming effect was larger in the positive prime-positive target condition than negative prime-negative target condition but not congruent effect. Experiment 2 employing a long SOA (500ms­1000ms) naming task didn't yield either positive priming effect or congruency effect. The congruency effect and the positive priming effect which is ubiquitous phenomenon in the generic cognitive concepts network were not found in the gender properties. Therefore, it was suggested that the social information including prejudice or stereotype can be differently processed according to the value of emotionality.

Despite importance of private brands in the retail industry, not many studies have been performed on factors affecting consumers' attitude formation toward private brands. This study tries to understand attitude formation toward private brands from the perspective of image congruence. Focusing on three types of image congruence-image congruence between a private brand and a consumer's self, image congruence between a store and a product category used for a private brand, and image congruence between a store and a consumer's self - this study explores relationships and effects of these three types of image congruence on attitudes toward private brands. According to results, image congruence between a private brand and a consumer's self has the strongest effect among three types of image congruence. Image congruence between a store and a product category also has a significant positive effect on attitudes toward private brands. Effects of image congruence between a store and a consumer's self on attitudes toward private brands were opposite to the hypothesized direction, and explanations about the unexpected result are provided.

Luxury goods products have a steady stream of consumers, and the latest trend is the sell and purchase markets. The consumers age groups also vary widely. This research examined the mediating effect of self-construal of the relationship between brand consistency and intention to purchase luxury fashion products. The analysis classified the brand consistency of luxury fashion products as social, actual, and the deal. First, the order of consistency that had an effect on self-construal appeared in the order of social cohesion, actual coincidence, and ideal coincidence. Second, an analysis of mediating effect of self-construal showed that only self-construal appeared to have a partial mediating effect on the relationship between the intention to purchase and the actual and ideal consistency. Such result can be interpreted as that when purchasing luxury fashion products, consumers have a tendency to desire that the brand would express their personal image and that it would match the perception they had of the brand, rather than a tendency to perceive the brand as a tool to help them perform their desired social role. These results suggest that consumers who consume the brand desire to have their personalities and subjective environmental conditions well expressed.

본 논문에서는 분산 공유 메모리(distributed shared memory) 시스템에서 데이터의 일치성(consistency)을 마감시간(deadline) 이내에 완료하기 위해서 새로운 실시간 프로토콜을 제안한다. 분산 공유 메모리 시스템에서 사용되는 공유 데이터는 여러 시스템에 복제를 할 수 있기 때문에 이들간 일치성을 효과적으로 유지시키기 위한 여러 방법이 연구되어 왔다. 기존의 방법들은 평균 액세스 비용을 단축시키기 위한 것이고 프로토콜에 따라 서로 다른 복사본의 개수를 갖게 되며 일치성 유지를 위한 비용은 시스템이 갖고 있는 복사본의 개수에 따라 증가한다. 각 노드가 서로 다른 데드라인을 갖는 실시간 분산시스템에서는 일치성 유지를 주어진 데드라인이내에 완료하기 위해서는 일치성 유지를 위한 비용을 줄이는 것도 요구되지만 데드라인이 상대적으로 급한 노드에 대한 우선적인 처리가 요구된다. 실시간 프로토콜에서는 각 분산 시스템에서 데드라인이 상대적으로 급한 노드가 항시 복사본을 갖게 하고 전체 복사본의 개수를 제한한다. 시뮬레이션을 통해서 실시간 프로토콜의 성능향상을 확인하였다.
