본 연구는 경주국립공원의 지구유형별 특성에 따른 관리정책에 대한 이용자의 인식 차이를 비교해 보고자 경주국립공원을 방문한 이용자를 대상으로 2012년 7월에서 8월까지 설문조사를 실시하였다. 경주국립공원 이용자의 특성, 이용행태, 공원관리정책에 대한 인식을 조사항목으로 설정하였다. 먼저, 경주국립공원 8개 지구의 주요자원과 탐방객의 이용특성을 기준으로 지구유형을 분류하였다. 불국사와 석굴암을 주요 자원으로 주로 경관감상 및 휴양을 위한 관광을 목적으로 하는 이용객들이 많이 찾는 토함산 지구는 관광형, 역사문화 학습과 환경 교육을 위한 탐방객들이 많이 찾는 남산과 대본지구는 역사문화교육형으로 분류할 수 있었으며, 남은 화랑, 서악, 소금강, 구미산 지구는 건강증진을 위한 체력 단련, 등산, 산책이 주목적으로 주민들이 많이 이용하는 공간으로 근린공원형으로 분류할 수 있었다. 관광형의 경우, 문화유적탐방을 위한 이용자가 집중되는 곳으로 이용자제한 정책을 통해 탐방객들의 만족도를 높일 수 있는 방안에 대해 고려해야 할 것으로 판단되었고, 역사문화교육형은 이용행위규제 방법에서 관리자 단속권한이 강화될 필요성이 있다고 인식하고 있었다. 반면, 근린공원형 지구의 이용자들은 대부분의 정책에 대해 가장 낮은 필요도를 느끼고 있었는데, 이러한 결과들을 통해 경주국립공원은 각 지구별로 이용자들이 느끼는 정책의 필요도가 다르다는 것을 알 수 있었다. 이러한 결과는 향후 경주국립공원의 지구별 이용자의 인식 차이를 반영한 정책 도입에 기초자료로 활용할 수 있을 것으로 기대된다.

The survey was taken from July to August 2012 by users who visited Gyeongju National Park to compare the perceived gap of users regarding management policy by characteristic of Gyeongju National Park district type in this study. Gyeongju National Park users' characteristic, use pattern and perception regarding park management policy were created as survey items. First, district type was classified based on use pattern of the visitor and the key resources of 8 districts in Gyeongju National Park. Tohamsan District, which has many visitors for the purpose of scenery appreciation and recreation with Bulguksa and Seokguram Grotto, is classified as tourism type, Namsan and Daebon District, which bring in many visitors seeking to learn about historical culture and environmental education, could be classified as historical culture education types, and Hwarang, Seoak, Sogeum River, Gumisan District are places residents use for physical training, hiking and walking to improve health, thus classifying them as neighborhood park types. People perceived that the tourism type is where users for historical artifact tours are concentrated, thus consideration for plans that can improve visitors' satisfaction from a user limit policy is required, and a manager's right to control use behavior must be reinforced in historical culture education types. On the other hand, users of neighborhood parks found the lowest necessity for most of the policy, and this showed that users of each of Gyeongju National Park's districts felt differently about the need for policies. This result is expected to be utilized as a database for introducing policy that reflects the perception of users in each districts of Gyeongju National Park in the future.

As there is a wide spread and rapid development of smartphones, the number of smartphone application is dramatically increasing. The transformation from wired to wireless Internet to mobile Internet environment leads to the important roles played by smart phone applications. Thus, the study aims to develop and propose the quality assessment model that is appropriate to smartphone applications, which is distinguishable from general purpose software assessment and examines the difference in perception on the quality factors between developers and user groups. The model consists of five external characteristics and the corresponding fifteen internal attributes that contribute to the evaluation of complicated elements included in smartphone applications. The authors applied the Analytic Hierarchy Process(AHP) method among multiple decision making methods and thus improved the reliability by assessing the subjective characteristics of related elements in an objective manner in order to evaluate the quality factors of developer groups, and tested the research hypothesis based upon the Technology Acceptance Model(TAM) in order to examine the impact of smartphone quality factors on the user group’s willingness to use consistently. The study revealed that the perception on the degree of importance of the quality factor was different among departments even within developer groups, and there was a significant difference in the perception on quality factor between developers and users. Through such processes, it was found that the planners had the most similar perception on the quality factor of smartphone application to the users concerned. In addition, it was found that the maximization of functionality, usability, and mobility led to the satisfaction of both users and developers while fulfilling the efficiency and security in order for the survival of applications, which leads to the development of high quality smartphone applications.

This study is the integrative research model on the performances of the internet shopping mall, which recently has been growing with rapidity. This research statistically analysed the effect that consumer characteristic like flow and value inclination and system quality, information quality and service quality have on use, satisfaction and consumer loyalty of an Internet shopping mall through questionnaires. This statistic analysis was carried out using AMOS, the statistic analysis. The results are the following: First, the appropriateness of the research model was high in general(GFI: 0.832, RMSEA: 0.049). Second, this research suggests that flow inclination among consumer characteristics have a positive effect on use and satisfaction while value inclination does not. Third, this research shows that system quality and information quality among information system characteristics have a positive effect on use and satisfaction while service quality have a positive effect on only satisfaction. Fourth, use of an Internet shopping mall doesn't have a negative effect on satisfaction. Fifth, use and satisfaction of an Internet shopping mall have a positive effect on consumer loyalty. The meaning of this study is that it is the integrative research model considering information system characteristic and consumer characteristic relevant to the performances of an Internet shopping mall. But in the future we need a study that can systematically analyse correlation between variables which can influence use and satisfaction.

본 연구에서는 미디어 이용과 충족 논의를 기본 모델로 설정하여 모바일방송 콘텐츠를 분석하였다. 특히 기존 모바일 연구들이 수용자를 단일화하여 분석하였다는 한계와 동종 산업의 타매체와의 관계를 배제한 채, 단일 매체의 이용동기만을 살펴보았다는 한계를 극복하고자, 방송매체 이용동기 집단으로 수용자를 세분화하여 각 집단의 모바일방송 활용 특징을 살펴보았다. 이를 위해 229명의 위성DMB 초기이용자를 대상으로 방송이용동기와 위성DMB활용 유형, 충족 정도, 그리고 적절 콘텐츠에 대해 조사하였다. 분석결과, 방송매체의 이용동기는 ‘도구적 지식추구군’, ‘다채널 접근추구군’, ‘경제적 접근추구군’, ‘유희적 오락추구군’, ‘휴대적 접근추구군’, ‘보도적 환경감시군’의 6개 수용자 집단으로 도출되었다. 위성DMB 이용행태와 관련한 분석에서는 아침·저녁 시간대의 출퇴근 길에서 많이 이용하고 있었으며, 구체적으로 오락추구집단은 점심시간의 이용이 높게 나타나고 있으며, 환경감시군과 지식추구군은 늦은 저녁시간의 이용도가 상대적으로 높게 도출되었다. 또한 채널추구군과 오락추구군은 대중교통 이외에 공공장소에서도 많은 이용을 하고 있었으며, 지식추구군은 자가승용차에서 주로 활용하고 있었고, 휴대추구군은 집에서의 이용이 높게 나타났다. 마지막으로 18개 프로그램 장르는 적절콘텐츠, 부가콘텐츠, 지양콘텐츠, 배제콘텐츠로 구분되었으며, 순서대로 DMB에서의 적합성이 높게 인식되었다. 적절콘텐츠 중에서는 오디오채널이 가장 적합성이 높게 나타났으며, 뉴스·스포츠·음악이 그 뒤를 이었다. 구체적으로 오락추구군은 음악과 오디오채널에 대해 높은 적절성을 인식하고 있었으며, 환경감시군은 대체로 오락추구군과 유사하나, 뉴스에 대한 적합성도 상대적으로 높게 인식하고 있었다. 휴대추구군은 뉴스와 스포츠를 적합하다고 응답하였으며, 경제추구군은 오디오 채널은 높으나, 음악 채널에 대해서는 낮게 인식하고 있었다.

Media uses and gratifications perspective discussion were set up as a basic model in this study, and DMB contents were analyzed. The this study was going to especially overcome a limit that existing study simplified a user and only a use action of a single medium was looked into in the state that eliminated relationship with other medium. Therefore, the sample was subdivided to a use needs group for looking into user characteristic of DMB. As a result of analyzing Six user groups of 'knowledge chase group', 'multichannel chase group', 'economy chase group', 'entertainment chase group', 'mobile chase group', 'news chase group' were drawn. The analysis result about DMB use action is as follows. It was used in a traffic road very much in the evening with the morning. 'entertainment chase group' used it very much at a lunch break, 'news chase group' and 'knowledge chase group' very used it in late evening time. Also, 'multichannel chase group' & 'entertainment chase group' was using it very much in a public place except public traffic, and 'knowledge chase group' was using mainly it in a car of the person oneself, 'mobile chase group' very used it in a house. lastly, the 18 program genres was stayed again in four categories of 'Appropriate contents', 'Additional contents', 'Not aimed contents', 'eliminated contents'. It was analyzed the thing that was appropriate for DMB in order. and especially, An audio channel appeared the most appropriate contents.

This paper presented a method to develop a relay model by the user-written model function of PSS/E. As for the voltage instability, although generator current limiters, transformer's tap-changers and dynamic loads have been considered as the dominant components, the protection system is also very important because it may influence the system's dynamic behaviour. Hence a distance relay model implemented with the suggested method was added, and then the operating characteristics of the distance relay under the voltage instability condition were investigated.
