Social network service (SNS) data related to green tourism were used to estimate preferred tour sites and users' interests. Keywords related with green tour activities were employed to search the SNS data. SNS data were collected from Korean blogs such as Naver and Daum from June $1^{st}$ to August $31^{st}$ between 2015 and 2017 using text-mining solution. During the study period, seven hundred and five posts were analyzed. Associated words that frequently co-occurred with keywords were classified into different categories depending on the nature of associated words. Associated words included swimming pools and camping sites (location); experience and swimming pools (attribute); and water play and culture (culture/leisure). Our data suggest that SNS users with experience of green tourism in Korea exhibited interest in green tourism with swimming pools, camping sites, experience, water play and/or culture rather than particular popular sites. Based on the findings, it is recommended that preferred facilities such as swimming pools should be provided at green tourism sites to meet the users' needs and to facilitate green tourism.

Incheon International Airport(IIA) is planned to open in about two years. Korean government has an ambition to make IIA a major hub airport in Northeast Asia. The most essential and required condition for an airport to be a successful hub airport in a certain region is to have more efficient flight service network than the other airports in the same region. IIA should compete with Japanese airports to be a major hub in Northeast Asia because Japanese government also has a plan to expand greatly the airport capacity in Tokyo area and Kansai airport in Osaka. It is necessary for both IIA and Korean national air carriers to compose efficient flight service network considering hub competition with Japanese major airports. As the liberalization of international air transport industry would give more marketing freedom to airlines, they would plan the flight service network and flight schedule based on market analysis instead of governmental regulations. In the economically liberalized environment, it is very required to analyze air passengers' flight choice behaviour in order to induce other carriers and passengers through IIA's attractive flight service network. Disaggregate model is more appropriate than aggregate model to analyze consumers' behaviour. The information derived from disaggregate choice model of air passengers could be utilized in devising efficient flight network and schedule plan. Value of travel time or trade off ratio between flight frequency and travel time which could be estimated from discrete choice model could be utilized for scheduling an efficient flight plan for airlines and composing efficient flight service network for IIA.

A new secure network communication technique that has been designed for mobile wireless services, is presented in this paper. Its network services are mobile, distributed, seamless, and secure. We focus on the security of the scheme and achieve anonymity and reliability by using cryptographic techniques like blind signature and the electronic coin. The question we address in this paper is, "What is the best way to protect the privacy and anonymity of users of mobile wireless networks, especially in practical applications like e-commerce?" The new scheme is a flexible solution that answers this question. It efficiently protects user's privacy and anonymity in mobile wireless networks and supports various applications. It is employed to implement a secure e-auction as an example, in order to show its advantages in practical network applications.

With the steady growth of mobile technology and applications, demand for more storage in mobile devices has also increased. A lightweight block-level protocol, Internet Advanced Technology Attachment (iATA), has been developed to deliver a cost-effective storage network solution for mobile devices to obtain more storage. This paper seeks to contribute to designing and implementing Load Balancing (LB), Network Monitoring (NM) and Write Replication (WR) modules to improve the protocol's scalability and data availability. LB and NM modules are invoked to collect system resources states and current network status at each associate node (server machine). A dynamic weight factor is calculated based on the collected information and sent to a referral server. The referral server is responsible to analyze and allocate the most ideal node with the least weight to serve the client. With this approach, the client can avoid connecting to a heavily loaded node that may cause delays in subsequent in-band I/O operations. Write replication is applied to the remaining nodes through a WR module by utilizing the Unison file synchronization program. A client initially connected to node IP A for write operations will have no hindrances in executing the relevant read operations at node IP B in new connections. In the worst case scenario of a node crashing, data remain recoverable from other functioning nodes. We have conducted several benchmark tests and our results are evaluated and verified in a later section.

It is absolutely essential to implement advanced IP network technologies such as QoS, Multicast, High Availability, and Security in order to provide real-time services like IPTV via IP backbone network. In reality, the existing commercial networks of internet service providers are subject to certain technical difficulties and limitations in embodying those technologies. On-going research efforts involve the experimental engineering works and implementation experience to trigger IPTV service on the premium-level IP backbone which has recently been developed. This paper introduces the core network technologies that will enable the deployment of a high-quality IPTV service, and then proposes a suitable methodology for application and deployment policies on each technology to lead the establishment and globalization of the IPTV service.

Peer-to-Peer (P2P) networks are attracting considerable research interest because of their scalability and high performance relative to cost. One of the important services on a P2P network is the streaming service. However, because each node in the P2P network is autonomous, it is difficult to provide a stable streaming service on the network. Therefore, for a stable streaming service on the P2P network, a fault-tolerant scheme must be provided. In this paper, we propose two new node selection schemes, Playback Node First (PNF) and Playback Node first with Prefetching (PNF-P) that can be used for a service migration-based fault-tolerant streaming service. The proposed schemes exploit the fact that the failure probability of a node currently being served is lower than that of a node not being served. Simulation results show that the proposed schemes outperform traditional node selection schemes.

이 논문은 최근 전 세계적으로 확산되어 다양한 분야에서 폭넓게 사용되고 있는 Social Network Service(SNS)가 오히려 사이버 범죄나 산업스파이 등과 같은 각종 불법적 행위에 악용되고 있는 상황에 즈음하여, 특히 SNS가 가지는 보안상 취약성으로 인한 위험뿐만 아니라 기업의 기밀정보·핵심기술이나 개인정보 유출, 프라이버시 침해, 신원 절도(ID Theft), 타인 정보의 오·남용, 지적재산권 침해 및 관련 법적 문제, 범죄 증거 및 수사자료 활용, 아동 포르노 등 성범죄에의 악용, 온라인상에서의 집단 따돌림(On-line Bullying) 등 각종 사회·경제적 우려가 중대하고 심지어는 테러나 사회적 파장이 큰 범죄의 목표 또는 수단이 되기도 하는 등 그 잠재적 위험성이 매우 크다는 점에 주목하였다. 사실상 국내 뿐 아니라 해외에서도 SNS의 위험성이나 Policing(경찰활동)에 미칠 영향 등과 관련한 연구가 거의 전무한 형국인지라 이에 SNS에 대한 위험성의 인식과 Policing 측면에서의 적극적인 검토와 대응이 시급히 요청되고 있는 실정임을 반영하여 이 논문을 통해 SNS의 잠재적 위험성에 대한 이론적 분석과 같은 학술적인 측면뿐만 아니라 경찰활동에 미칠 수 있는 영향에 대한 실무·실용적 관점에서 접근의 필요성을 인지하여 탐색적 연구를 시도하였다.

This exploratory study aims to review the risks and threats of social network services(SNSs), particularly focusing upon the policing perspective. This paper seeks to acknowledge the present risk/danger of SNSs and the very significance of establishing a strategic framework to effectively prevent and/or control criminal misuse of SNSs. This research thus advocates that proactive study on security issues and criminal aspects of SNSs and preventive countermeasures can play a significant role in policing the networked society in the time of digital/internet age. Social network sites have been increasingly attracting the attention of entrepreneurs, and academic researchers as well. In this exploratory article, the researcher tried to define concepts and features of SNSs and describe a variety of issues and threats posed by SNSs. After summarizing existing security risks, the researcher also investigated both the potential threats to privacy associated with SNSs, such as ID theft and fraud, and the very danger of SNSs in case of being utilized by terrorists and/or criminals, including cyber-criminals. In this study, the researcher primarily used literature reviews and empirical methods. The researcher thus conducted extensive case studies and literature reviews on SNSs. The literature reviews herein cover theoretical discussions on characteristics, usefulness, and/or potential danger/harm of SNSs. Through the literature review, the researcher also concentrated upon being able to identify a strategic framework for law enforcement to effectively prevent criminal misuse of SNSs The limitation of this study can be lack of statistical data and attempts to examine previously un-researched area in the field of SNS and its security risks and potential criminal misuse. Thus, to supplement this exploratory study, more objective theoretical models and/or statistical approaches would be needed to provide law enforcement with sustainable policing framework and contribute to suggesting policy implications.

최근 증가되고 있는 모바일 SNS(Social Network Service)를 통한 매개(Mediated) 커뮤니케이션에서 자신의 감성을 표현 가능한 이모티콘을 활용하여 대화하는 감성 커뮤니케이션이 발달하고 있다. 이모티콘 개발이 증가하고 사용이 대중화가 됨에 따라, 사용자가 원하는 감성 표현이나 의미를 상징하는 아이템에 대한 요구가 확대되고 있다. 또한, 동일한 이모티콘이라도 사용자에 따라 다르게 해석할 수 있으며, 디자이너의 의도한 감성 표현에 대해 사용자의 의미 해석이 상이할 수 있다. 따라서 본 연구에서는 모바일 SNS 메신저에서 이모티콘을 이용한 커뮤니케이션을 위해 사용되는 감성 어휘를 연구하고 분류하여 감성 커뮤니케이션과 관련된 이모티콘 개발의 초석을 마련하고자 한다. 즉, 사용자 관점에서 이모티콘에 기반하여 표현하고자 하는 감성 어휘에 대한 분류와 모델을 제안한다. 본 연구를 위해 첫째, 문헌조사를 기반으로 감성 형용사를 수집하고 설문, 통계 분석 및 FGI (Focus Group Interview)를 통해 1차 감성 어휘를 추출한다. 둘째, 2차 설문조사 및 통계분석을 통해 최종 적합 어휘를 추출한다. 셋째, 최종 추출된 어휘를 바탕으로 다차원척도 분석을 실행하여 어휘 모델을 도출하고 감성 어휘를 분류한다. 그 결과 ‘미안하다’, ‘바쁘다’, ‘배고프다’, ‘어렵다’, ‘슬프다’, ‘날씨가 춥거나 덥다’, ‘지루하다’, ‘부끄럽다’, ‘궁금하다’, ‘만족하다’, ‘좋다’, ‘아름답다’, ‘편안하다’ 의 13개 어휘로 분류되었다.

Recently, emotional communication has been developed by emoticons that express user emotion in mediated communication through mobile Social Network Service(SNS). As the development of emoticons increases and the usage becomes more popular, there is a growing demand for items that express the emotional expression and desired meaning by the user. And also mis-communication can occur through different interpretation amongst users. Additionally, the meaning interpreted by the users may be different from the designers’ intended emotional expressions. In this study, we propose a model by classifying emotional vocabularies. First, we collected emotional adjectives and extracted the first set of vocabularies with questionnaires, statistical analysis and FGI (Focus Group Interview). Second, we extracted the final set of proper vocabulary from the first set of vocabularies with a second set of questionnaires and statistical analysis. Third, with the final set of vocabularies an emotional vocabulary model was built based on the multidimensional scale analysis. As a result, the model was classified into 13 categories, which are as follows: sorry, busy, hungry, difficult, sad, the weather is cold or hot, boring, ashamed, curious, satisfy, good, beautiful, and comfortable.

The Web Services infrastructure is a distributed computing environment for service-sharing. Mechanisms for Web services Discovery proposed so far have assumed a centralized and peer-to-peer (P2P) registry. A discovery service with centralized architecture, such as UDDI, restricts the scalability of this environment, induces performance bottleneck and may result in single points of failure. A discovery service with P2P architecture enables a scalable and an efficient ubiquities web service discovery service that needs to be run in self-organized fashions. In this paper, we propose an autonomic <K, D>-interleaving Registry Overlay Network (RgON) that enables web-services' providers/consumers to publish/discover services' advertisements, WSDL documents. The RgON, doubtless empowers consumers to discover web services associated with these advertisements within constant D logical hops over constant K physical hops with reasonable storage and bandwidth utilization as shown through simulation.
