최철재,이형봉,차홍준 강원대학교 기초과학연구소 1999 기초과학연구 Vol.10 No.-

UNIX 운영체제에서 제공하는 신호는 서로 다른 UNIX판에서 미묘한 차이점을 가지기 때문에, 신호를 사용함에 있어서 많은 혼란과 오용의 원인이 되고 있다. 뿐만 아니라 신호에 대한 부정확한 이해에 근거하여 작성된 많은 UNIX응용프로그램들이 심각한 잠재 오류를 간직한 채 운용되고 있기도 하다. 이런 상황을 예방하고 교정하기 위하여, 이 논문에서는 UNIX운영체제에서 제공하는 신호의 근본 개념과 구현 방법을 운영체제 측면에서 살펴보고, 무의적으로 이루어지는 신호 오용의 몇 가지 예를 통해 문제점을 도출한 후, 이 해결 방안을 제시한다.

최철재,Unurjargal Baatarchuluun 한국유통경영학회 2022 유통경영학회지 Vol.25 No.1

Purpose: The purpose of this study is to verify the causal relationship between perceived brand prestige, brand trust, brand identification, and brand loyalty in the context of luxury brand purchase, and to identify the mediating role of brand trust in the relationship between these constructs. In addition, this study intends to examine the mode rating effect of self-esteem on the relationship between perceived brand prestige, brand trust, brand identification, and brand loyalty. Research design, data, and methodology: Data for this study were collected through face-to-face interviews with 281 customers who purchased or shopped for luxury products at various luxury stores. Reliability was confirmed by Cronbach’s α coefficient through internal consistency analysis for constructs identified in EFA. Convergence validity was confirmed by performing confirmatory factor analysis to derive measurement models for each research unit for the measured items. Discriminant validity was checked by comparing whether AVE was greater than the correlation squared value. Structural Equation Modeling Analysis was used to verify model fit and hypotheses. Results: As a result of analyzing the direct influence relationship between each component, perceived brand prestige had a positive effect on brand trust and brand loyalty, but did not affect brand identification. In addition, it was found that both brand trust and brand identification had a positive effect on brand loyalty, and the mediating effect of brand trust was confirmed in the relationship between perceived brand prestige and brand identification. As a result of analyzing the moderating effect of self-esteem, it was confirmed that there is a moderating effect of self-esteem in the relationship between perceived brand prestige and brand trust. However, it was confirmed that there was no moderating effect of self-esteem in the relationship between perceived brand prestige, brand loyalty, and brand identification. Implications: Luxury store managers must present brands that fit their identities in order to build a database of profitable customers and increase brand trust and brand loyalty. Additionally, since people with high self-esteem evaluate themselves positively and motivate them to engage with others socially, frontline workers must strengthen brand trust by providing superior service to highly profitable and high-esteem customers. Based on such high brand trust, companies or managers need to increase brand loyalty

대형유통업체의 농식품 만족요인이 점포신뢰와 재구매의도에 미치는 영향

최철재 한국국제농업개발학회 2012 韓國國際農業開發學會誌 Vol.24 No.2

연구결과의 요약 및 논의 본 연구에서는 농식품의 주요 소비자판매처인 대형할인점과 대형슈퍼마켓을 대상으로 품질 및 고객서비스만족과 구매의 경제적 가치만족이 점포신뢰와 재구매의도에 미치는 영향력을 장기관계지향고객과 단기거래지향고객으로 분류하여 검증하였다. 분석결과, 대형할인점의 장기관계지향고객의 경우 품질 및고객서비스만족은 점포신뢰에 그리고 구매의 경제적가치만족은 점포신뢰와 재구매의도에 영향을 주었고, 점포신뢰는 재구매의도에 영향을 주는 것으로 나타난 반면 단기거래지향고객의 경우 구매의 경제적가치만족 만이 점포신뢰에 영향을 주는것으로 확인되었다. 그러나 대형마트 장기간 관계지향고객에서는 구매의 경제적가치만족이 점포신뢰에 영향을 줌으로써재구매의도를 형성한 반면 단기지향고객에서는 구매의 경제적가치만족과 점포신뢰가 동시에 재구매의도에 영향을 주는 것으로 확인되었다. 이상의 연구결과를 바탕으로 다음과 같은 논의를 할 수 있다. 첫째, 대형할인점의 경우 장기관계지향고객은 점포 내 제품의 품질과 고객서비스 수준 그리고 구매 시경제적 가치 등 모든 요소를 고려하여 점포에 대하여 만족하게 되며, 또한 점포가 이들 만족요인을 고객에게 제대로 제공할 때 이용하는 점포에 대하여 신뢰하고 재구매의도를 강력하게 나타난다는 것을 알 수 있다. 따라서 장기간 관계지향고객에게는 점포에 대한 만족수준을 높이는 것이 중요하다. 구체적으로는 최신 정보기술(information technology)을 활용하여이용 고객의 데이터베이스를 구축하고, 개인화된 고객의 특성과 구매행동에 관한 정보를 축적하여 관계지향고객을 선정 한후 이들에게 제품 및 서비스에 대한 정보 및 가격과 판매촉진에 관한 정보를 DM(direct mail)이나 홈페이지에 적극적으로제시함으로써 점포이미지를 높이고 표적고객의 욕구를 충족시켜 점포에 대한 신뢰와 반복구매를 높일 수 있다. 그러나 단기거래지향고객은 구매 시 단지 가격구조나 판촉행사를 통한경제적 가치만을 고려하기 때문에 제조업체 브랜드(national brand)보다는 유통업체 브랜드(private brand)상품을 제시하여가격매력성을 높이고, 시간대별 판촉행사를 통해 고객의 점포에 대한 신뢰를 유도할 필요가 있다. 둘째, 대형슈퍼마켓에서는 관계지향고객이나 거래지향고객 모두가 구매의 경제적가치만을 우선적으로 고려하므로 가격정책에 역점을 둘 필요가 있다. 그러나 장기관계지향고객은 점포신뢰를 통해 반복구매의도를 형성하지만 단기거래지향고객은 직접적으로 재구매의도를 나타내므로 고객의 성향에 따라 분류하여 관리할 필요가있다. 즉 관계지향고객에게는 가격정책을 통하여 점포신뢰를꾀하여야 할 것이며, 거래지향고객에게는 판촉행사나 저가격정책 등으로 직접적인 반복구매를 유도해야 할 것이다.

최철재,박승환 한국국제농업개발학회 2008 韓國國際農業開發學會誌 Vol.20 No.3

The notion that relationships are more profitable than individual transactions is well founded, but the search for a framework to qualify, diagnose, and describe has proven elusive in case of agricultural product store. So, this study set out to the process of store loyalty through relationship formation with customer in types of agricultural product store. A model is proposed to evaluate the relationships between store satisfaction, store trust, store commitment and store loyalty by types of agricultural product store. The research results from regression showed as followed. First, store satisfaction had effect on store trust and store trust had effect on store loyalty in specialty agricultural product store. Second, store satisfaction had effect on store trust and store trust had effect on store commitment and store commitment had a strong effect on store loyalty in discount store. Third, store satisfaction had a direct effect on both store trust and store commitment, not effect on other variables, in department store. To enhance store loyalty, types of agricultural product store should build up relationship with their customer because loyalty translates into increased customer relations and repurchase which is reflected in a retailer's economic returns. The higher levels of trust and commitment are associated with higher levels of customer retention and inevitably, organsational profitability.
