본 연구는 국적 항공사를 이용하여 해외여행을 떠나는 아웃바운드 여객들이 인식하는 국적 항공사의 객실서비스 품질이 그들의 관광지 관광체험과 관광만족도에 어떠한 영향을 미치는지 실증 분석하였다. 왜냐하면 국적항공사는 우리나라를 대표하는 항공사이기 때문에 한국을 여행하려는 외국인 인바운드 여객의 긍정적인 국적항공사의 서비스품질 인식은 한국여행 관광만족을 증대시킬 수 있는 중요한 요인이 될 수 있기 때문이다. 실증분석을 위해 국적항공사를 이용하는 관광이 여행목적인 내국인 승객들을 대상으로 설문지를 배포 후 회수하여 실증분석을 실시하였다. 연구자는 해외로 아웃바운드 관광을 떠나는 내국인 승객들에 대한 실증분석을 통해서 유의미한 분석결과가 도출된다면, 역으로 한국을 관광지로 하여 인바운드 관광을 오는 외국인 여행객들에게도 적용가능한 시사점을 제시할 수 있다고 판단하였기 때문이다. 따라서 여행객이 인식하는 항공사 객실서비스 품질, 관광지 관광체험 및 관광만족도를 선행연구들을 통해 이론적 측면에서 고찰하고 잠재변수들 간 통계적으로 유의한 인과관계를 도출하였다. 분석 결과 항공사 객실서비스 품질은 친절성, 반응성, 용이성 및 유형성으로 구분되었다. 객실서비스 품질에 대한 긍정적인 인식은 인지적 관광경험과 정서적 관광경험을 매개로 하여 궁극적으로 관광만족도에 영향을 미치는 것으로 판명되었다.

The primary concerns of recreation plan are to provide visitors with quality of recreational experience and to protect of recreation resources. The quality of recreational experience is often defined in terms of social carrying capacity. The carrying capacity is revealed as perceived crowding. In this respects, measuring perceived crowding is useful tool of social carrying capacity determination. This study is to test the structural equation model that includes variables affecting perceived crowding. Through an on-site questionnaire survey, 467 visitors on Naejangsan national park were collected. The results of the study are follows. The encounter level on facility area is higher evaluated as crowding factor than other area in the park. It can be concluded that visitor perceived crowding when facility area situates high density use level rather than other areas expose high density use level. In the path analysis, the input variables(attitude, experience, encounter level) on the structural equation model affect significantly on perceived crowding. Especially, the attitude on the park management polocy is the most affecting factor on perceived crowding.

The Quality of Experience (QoE) of next Generation wired/wireless network services based upon IP networking is becoming a popular issue in recent years. The user experience of Internet services such as IPTV, online game, web surfing and etc, are becoming the most desirable factors to service providers to improve service performance and customer's satisfaction. However, collecting user experience from customers and obtaining the QoE parameters from the Quality of Service (QoS) parameters such as bandwidth, delay, jitter or admission control algorithm, are difficult subjects because of the various service types and user characteristics. In this paper, we propose a framework which contains service classification, QoE analysis and service enhancement steps for a suitable QoE measurement and management protocol. We define the user satisfaction indicators of the Internet services, classify the categories of each type of services, and analyse the Key Performance Indicator (KPI) in each type of services to perform the QoS parameters and improving the service qualities.

This study provides a framework to assess network design under the regime of QoE (Quality of Experience). Our approach is expected to reveal the necessity of developing the QoE measures and applying this notion to network design, particularly in the mobile environment. Furthermore, our model shows the ample potential that both users and network providers are able to attain a win-win case by shifting the focus on network design and service operations from QoS (Quality of Service) to QoE. Since the former considers only relevant technological specifications, it may fail in capturing critical factors surrounding users, such as a context where the corresponding user is working on. For example, according to one study [13], the bit-rate, a widely employed QoS measure, shows inferior performance in provisioning network resources to the MOS (Mean Opinion Score), a representative QoE measure. Our framework develops the idea and construct a prototype to systematically assess network design and operations in terms of QoE. The proposed prototype aims at achieving a higher level of efficiency without severely deteriorating users' satisfaction level. We also provide some simulation results which support our idea. That is, reducing the chance of over-provisioning on the basis of the QoE paradigm results in a great flexibility. It may give price cut for users or postponement of network investment for providers or both. Our simulation results also seem robust irrespective of the forms of the QoS-QoE relationship.

Objectives: The purposes of this study was to describe workers' perceived values and the affecting factors (pros and cons) of the experience education for occupational safety and health and to suggest the strategies and future directions to improve the experience educational quality. Methods: A total of 8 male workers taking the safety and health education of the 7 safety experience education centers involved in this study (5 centers managed by Korea Occupational Safety and Health Agency (KOSHA), 2 centers of large commercial companies). This study used Photovoice, a qualitative method, as the study method. We conducted the photovoice-based in-depth interview with the SHOWeD questions and strategy and used the taxonomical analysis. Results: The study participants' perceived values of experience education were strengthening self-efficacy of the safety and health practices, providing practically useful information, and enjoying refreshing experiences different from daily jobs. Positive affecting factors of the experience education (pros) were providing the educational environments and opportunities of direct experiences, teaching practical safety and health contents for the participants, and the trainer's instruction competencies. Negative affecting factors of the experience education (cons) were learner's negative or standing postures during trainer's lecturing, insufficient exercise conditions and facilities for education, and difficult and theory-oriented lecture far from the practical jobs in reality. Conclusions: Major values of exercise education were direct experiences, useful contents and interesting opportunities from the education participants' perspectives. To improve the exercise education quality, overall educational environments such as convenience facilities as well as exercise facilities should be modified altogether. This study partially and conveniently used the photovoice method as the study limitation.

최근 HTTP 적응적 스트리밍(HTTP adaptive streaming) 서비스가 주목을 받고 있다. 기존 HTTP 적응적 스트리밍 서비스의 비디오 품질 조절 기법은 네트워크의 대역폭이나 클라이언트의 버퍼량에 따라 비디오 품질을 조절한다. 그러나 기존 품질 조절 기법은 빈번한 대역폭 변화나 고정된 버퍼 임계로 인해 불필요한 품질 변경이 발생하여 QoE(Quality of Experience)가 저하되는 문제가 있다. 본 논문에서는 변화하는 네트워크 환경에서 HTTP 적응적 스트리밍 서비스의 QoE 향상을 위해 평균 비디오 품질을 높이면서 불필요한 품질 변경을 최소화하는 비디오 품질 유지 기법을 제안한다. 제안하는 기법은 버퍼 점유율과 비디오 품질이 높을 경우 품질 유지 기간을 길게 설정하여 높은 품질을 오래 유지한다. 실험을 통해 제안하는 기법이 평균 비디오 품질을 향상시키고 품질 변경을 최소화하여 QoE를 향상시키는 것을 확인하였다.

Diffusion of e-learning has been accelerated according as the convenience and effectiveness have been increased rapidly due to the advancement of information technology. However, there has been few studies on systematic evaluation of its performance. SERVQUAL model was applied to evaluate the service quality of a 100% on-line lecture opened in a major Korean university. Two classes, one for 71 undergraduate students, the other for 79 graduate students, were opened for the lecture. The gaps between the expected service and the perceived service scores were compared with respect to sex, age, and e-learning experience. Although the gap score of male and female students were not different significantly, the gap scores among the other comparative groups were different. The perceived score of the older group with more than thirty ages was lower than that of the younger group. It seems that the older group evaluated the score based on the practical use of the subject since they are part-time students with jobs. Also, the perceived score of the group with previous e-learning experience was higher than that of the group with no e-learning experience. It seems that the experienced group evaluated it compared with the previous e-learning satisfaction. As it might be expected, the groups with higher perceived scores had stronger intention to recommend the e-learning lecture to other students.

Mobile applications market has emerged as new business model. The purpose of this study is to analyze the factors of mobile applications adoption. Based on prior studies of TAM and mobile technology/service, service quality, user experience, OS compatibility, self-efficacy, innovativeness, perceived usefulness, perceived ease of use, and cost were identified as affecting factors of mobile applications adoption. According to the results, service quality is significantly related to the perceived usefulness, and self-efficacy and innovativeness are significantly related to the perceived ease of use. User experience was also found to be related to both the perceived usefulness and the perceived ease of use. In case of OS compatibility, it was found to be significantly related to the perceived ease of use, but not to the perceived usefulness. Both the perceived usefulness and the perceived ease of use were found to be related to the adoption of mobile applications. However, cost was not found to be significant to the relationship between the perceived usefulness/the perceived ease of use and the adoption of mobile applications. This study contributes to provide the base of activation strategies and practical implications for mobile applications.
