A positive destination image has an impact on the tourist arrivals and economic growth of the tourist destination. Recently, the content generated by sharing tourist experiences and destination information on the internet has been increasing. The online content has the potential to become a major tourist decision source and provide more in-depth materials and richer content to extract destination image, insight and tourist's perceptions of the destination. This study was designed to explore the destination image of Daegu online and draw lessons for successful image management in an era of big data. Text mining approach and social network analysis were conducted to extract destination image determining elements and assess the influence of the elements. The result showed that destination image elements related to tourist infra-structures and culture, history and art affected the overall destination image of Daegu. Destination marketers should make an effort to grasp these precise destination image and seek ways to boost competitiveness as a tourist destination.

The objectives of this study are to analyze the effects of major factors influencing cruise ship passengers' satisfaction with a port of call on overall satisfaction with it and the differences in satisfaction with the domestic port of calls. To achieve these objectives, as a conceptual framework of the study, cruise tourism and tourist satisfaction were reviewed, and the empirical studies on cruise ship passengers's perceptions toward the Korean port of calls were conducted. According to the findings of this study, the following suggestions were presented to the local governments with the port of calls. The local governments are required to improve the food services provided around the port of call areas, and in addition, in case of Cheju, improvement of tourism information service which is verified as the most significant factor affecting passenger's overall satisfaction with the port of call is needed as well.

A local storage of HTML5 is a Web Storage, which is stored permanently on a local computer in the form of files. The contents of the storage can be easily accessed and modified because it is stored as plaintext. Moreover, because the internet browser classifies the local storages of each domain using file names, the malicious attacker can abuse victim's local storage files by changing file names. In the paper, we propose a scheme to maintain the integrity and the confidentiality of the local storage's source domain and source device. The key idea is that the client encrypts the data stored in the local storage with cipher key, which is managed by the web server. On the step of requesting the cipher key, the web server authenticates whether the client is legal source of local storage or not. Finally, we showed that our method can detect an abnormal access to the local storage through experiments according to the proposed method.

The criteria of operating anchorage and the unit of anchorage capacity have not been unified and the different terms have been used in same matters in each regulations related to the anchorages provided in major domestic ports. The competent authorities and vessels which are going to use anchorages are confused due to those situations. This paper suggests the schemes to unify criteria of operating anchorage, the unit of anchorage capacity and terms used in same matters through reviewing the anchorage operating regulations provided in major domestic ports. In addition, this paper suggests that the principles of anchorage naming, the unit of anchorage capacity and the number of vessels that can be accommodated should be established at the next revision of regulations through reviewing the status of anchorages in major foreign ports to minimize the confusion on operating anchorages.

Openstack is an open source software that enables developers to build IaaS(Infrastructure as a Service) cloud platforms. Openstack can virtualize servers, networks and storages, and provide them to users. This paper proposes the structure of Openstack cloud storage system applying Infiniband to solve bottlenecking that may occur between server and storage nodes when the server performs an I/O operation. Furthermore, we implement all flash array based high-performance Cinder storage volumes which can be used at Nova virtual machines by applying distributed RAID-60 structures to three 8-bay SSD storages and show that Infiniband storage networks applied to Openstack is suitable for virtualizing high-performance storage.

Five and more leg intersections have been still in operation in many urban areas. The number of conflicts in five leg intersection is more than four leg intersection. The signal timing design in the five leg intersection should be performed not only to reduce delay but also to increase safety. This paper suggests safety enhanced signal phase sequence design of a rotary with five leg intersection such as phase sequence minimizing the number of conflict points at the rotary with five leg intersections and the phase-length-design procedure by utilizing the Traffic Network Study Tool(TRANSYT). Field data was collected from Gonguptap five leg intersection in Ulsan and TRANSYT-7F was applied for signal timing design model. Optimal signal phase length and sequence of TRANSYT-7F is rearranged based on the Principal of "two moving traffic flows per phase". In conclusion, proposed signal phase design increased delay by 6.2% compared with the optimal signal phase of TRANSYT-7F. However, it could decrease the number of conflict in the five leg intersection by 61.5%.

We use the properties of competitive location equilibrium to study the relationship between the demand for education and the choice of primary residential location. Consumers can work and live in a comparatively high wage place where there are few education opportunities, or live in a place where education is available and commute to work. If education and employment are each location-specific, there are pooling equilibria in which consumers locate according to their preference for education. In general, the stronger the taste for education, the greater the attraction of living close to the education site and the lower the demand for other goods, including housing. Exploring the effects of the model parameters on the spatial distribution of consumers, we find that a higher frequency of trips taken to the education site, a shorter distance between the work place and the education site, or a greater out-of-pocket education cost each leads to a wider range of consumer types selecting to reside at the education location. We also find that a higher wage lowers the range of consumers who select to live near the education site.

This research the impacts of the tourism service quailty to the beahvioral intentions and loyalty to the results are as follow. Study results showed that the quality and behavior of tourist loyalty significantly affecting. Through these results, first, we could suggest one for the tourist to improve the quality of future loyalty to the new material could present on the tourist destination of Cheongbuk. Second, applied quality is important to know was intangible goods such as tourism and tourism quality as new research on the tourist destination of Cheongbuk. These results can be presented to expand the coverage associated with the quality of the tourist academically based. Tourist destination of industrial brand strategy was able to give many implications.
