This study investigated the customer equity driver's influence on customer loyalty in a travel fair. Customer loyalty is an important factor influencing corporate profits, as such the customer can be considered a corporatation's asset. It is the trend nowadays to increase customer equity, and 'customer equity' is a driver of this change. According to Rust et al. (2000; 2004), there exists three important customer equity drivers: value equity, brand equity, and relationship equity. This study focuses on the mediating and moderating role of involvement of the relationship between customer equity drivers and customer loyalty. Data was collected from 143 participating companies at the 2013 Naenara Travel Fair. Results support the mediating role of involvement in the causal relationship of customer equity drivers and customer loyalty. Regression analyses indicates that brand equity has a greater effect on customer loyalty than value equity or relationship equity. Practical implications and research recommendations are discussed.

유광민,김남조 한국관광학회 2009 관광학연구 Vol.33 No.6

This study was to suggest tourism resource development strategies of Yoo-yang dong, Yangju city using Space Syntax. Space Syntax is a analytical tool to abjectly evaluate structural characteristics of a space. In particular, it quantitatively analyzes the relationship between spatial structure and tourists' use pattern using three elements: average depth, degree of integration, and degree of control. Results found that the degrees of integration of some historical places in Yoo-yang dong were relatively low even though it was not far away from entrance places. Based on the Space Syntax, two alternative trails were proposed. Results from this study imply that Space Syntax could provide a guideline for place marketing and installation of trails.

This study adopted the power and game theories to find the primary causes and structure of the conflict among the community involved in Muju tourism & leisure city. In-depth interviews for stakeholders were conducted to collect the data. Authors find that gamer rationally decides conflict strategy in the structure of unbalanced powers between gamers. The gamer also takes conflict strategy when there is no confidential network between gamers. However, if there is confidential network(e.g. governance) between gamers, the gamer rationally takes collaboration strategy to obtain maximum benefits. This study implies that it is very difficult to virtually make a collaborated relations among stakeholders in lack of confidential situation.

유광민,최영석 한국관광학회 2012 관광학연구 Vol.36 No.4

The concept and notion of space and its realm of meaning vary significantly according to its configurational change. Space syntax is a method to analyse space configuration and is used in the various disciplines such as architecture and urban planning and design; which produces objective, quantifiable indicators. The investigation of theme park space offers a representative setting for understanding the role of space and how it impacts modern leisure and consumption through social logic. The space arrangement and site layout at theme parks and the resulting tourist flow have a direct impact of visitor experiences; in particular, the flow of congestion throughout traffic areas and its influence visitor consumption patterns. This study using Space Syntax was conducted to investigate how space is configured at Everland Theme park space in South Korea to promote user consumption. The findings confirm that Everland’s space configuration facilitates user wandering and by dispersing user flow and that its facilities stimulate impulsive consumption and greater involvement. 공간의 의미와 기능은 공간의 구성변화에 따라 다양하다. 관광공간은 사회적 논리에 의해 구성된다. 주제공원은 현대사회의 여가와 소비를 조직하기 위한 전형적인 소비 공간이다. 공간구문론은 공간구성을 분석하는 방법 중의 하나이며, 도시 교통로나 쇼핑몰의 배치 등의 다양한 분야에서 사용되고 있다. 그리고 수량화된 객관적 지표들을 제공한다. 주제공원은 보다 많은 시간과 돈을 소비하기 위해 의도적으로 만들어진 전형적인 소비 공간이다. 관광객의 흐름은 소비에 영향을 미치고 공간의 배치에 다라 영향 받는다. 주제공원의 공간은 보다 더 많은 시간과 돈을 소비하도록 구성된다. 본 연구는 공간구문론을 활용하여 한국에서 가장 대표적인 주제공원인 에버랜드의 공간구성이 어떻게 소비를 촉진하도록 만들어지고 있는지를 분석하고자 수행되었다. 에버랜드 주제공원은 이용자의 흐름을 확산시키고 배회를 촉진하는 공간구성을 가지고 있다. 그리고 충동적 소비를 촉진하기 위한 시설들은 모다 더 많은 이용자들의 흐름과 만날 수 있는 지점에 위치하고 있다. 이러한 공간구성과 시설들의 입지는 주제공원에서 보다 더 많은 시간과 돈의 소비를 촉진하기 위한 결과물들이다.

유광민 한국관광학회 2012 관광학연구 Vol.36 No.10

Onyang hot-spring resort was formerly used as a hot-spring cure by Kings of the Joseon Dynasty was changed into a destination visted by members of the former Japanese colonial government and by upper social class members whom visited the site for honeymoon purposes. This study conducted analysis how Onyang Hot-spring resort became an upper social class honeymoon destination under Japanese colonial rule. Onyang, in the former modern society, was an object of mimetic desire as space of sacred hot-spring cure. The colonial modern society newly reconstructed the model of mimetic desire on and space of Onyang hot-spring resort, where it became an example of a modern object of mimetic desire to persue. And hot-spring resort was also organized culturally as an admire object which served to justify Japanese colonial rule. Honeymoon is conducted by mimetic desire to play a role of sacred model Onyang hot-spring resort which became object of mimetic desire of modern society could be preferred as honeymoon destination. Preference and change as honeymoon destination can be explained by the model change of mimetic desire and cultural change of tourist gaze about destinations.

관광지 재생 연구방향 모색을 위한 관광지 재생 의미와전략 선행연구 분석

유광민,장병권 한국관광학회 2012 관광학연구 Vol.36 No.5

This paper seek to contribute to the study of tourism destination regeneration by analysing the historical and contextual elements of destination regeneration and past strategy studies. Academic interests pertaining to tourism destination regeneration has been deficient; perhaps partly due to the lack of mutual agreement on the concept and how it’s defined. Previous related studies which focused on Butler‘s Resort Life Cycle Model do not address considerations related to information on social factors or the regeneration strategies of capital and agencies. The analysis confirms that tourism destination regeneration should also be considered according to a development paradigm with recognition of social and relationship change; prompting a multidimensional strategy which includes the physical surrounding, political and economical, and cultural factors. It is necessary to develop theories that can better understand the social relationship and other practices to have space production and reinforce the application of tourism destination regeneration studies. 이 연구는 관광재생의 의미와 재생 전략에 관한 선행연구에 대한 분석을 통해 관광지 재생연구 방향을 모색하기 위하여 수행되었다. 관광분야에서의 관광지 재생에 대한 학문적 관심은 매우 부족한 상태이다. 그리고 관광지 재생의 의미에 대한 이해 또한 합의되어있지 않다. 버틀러의 리조트 라이프사이클 모델에 의존하여왔던 이전의 관광지 재생연구들은 자본과 행위주체의 전략과 관광지를 변화시키는 사회적 요인에 대한 이해와 정보를 제공해주지 않는다. 관광지 재생은 사회변화에 따른 개발패러다임과 사회적 관계의 변화에 대한 이해를 추구해야 하며, 이는 물리적 환경과 정치경제적인 그리고 문화적 영역을 포함하는 종합적인 전략으로 이해되어야 한다. 이러한 연구를 위해서는 관광지 재생전략에 대한 이해를 강화시키고 관광공간의 생산을 발생시키는 사회적 관계와 실천을 이해할 수 있는 이론의 적용과 개발이 요구되고 있다.

유광민,임성규,이준영,Yoo, Kwang-Min,Lim, Sung-Kyoo,Lee, Jun-Young 한국반도체디스플레이기술학회 2006 반도체디스플레이기술학회지 Vol.5 No.3

A low cost PDP sustain power supply is proposed based on flyback topology. By using Boundary Conduction Method(BCM) to control input current regulation, DCM condition can be met under all load conditions. Another feature of the proposed method is that a excessive voltage stress due to the link voltage increase can be suppressed by removing link capacitor and suggest new 'Level-shifting switch driver'. this new gate driver is improved 66% of efficiency than switching loss of a existed push-pull amplifier. The proposed converter is tested with a 400W(200V-2A output) prototype circuit.
