In terms of realizing the future e-government such as intelligent government, this paper attempts to provide an earnest and insightful reflection and suggests desirable strategies with regard to the four different crucial elements including electronic voting, electronic contract, resident registration/electronic document management, and real-estate registration as an operating strategy of intelligent government and the fourth industrial revolution regarding. The 4th industrial revolution is aimed at concentrating information or data characterized with sharing, opening, communicating and releasing in cloud computing system, analyzing big data, collecting information, and flourishing people's well-being by information and communications technology with utilizing the smart devices. Therefore, reliability of the pivotal information or data is critical and it is important for the participants being transparently shared, without the data or information being forged. In this respect, introduction or application of block chain technology is essential. This paper will review preceding studies, discuss the aspect of the 4th industrial revolution and intelligent government, then suggest operating strategies in the field of electronic voting, electronic contract, management of resident registration and electronic document and real-estate registration.

This article reviewed issues in Korean geographical journals: web GIS and National GIS. Web GIS in Korea is now evolving to mobile GIS, which requires portable hardware, wireless Internet, and GPS receiver. The new trend of mobile GIS is using a smart phone. Recently, a variety of studies for the mobile App and mobile Web in Korea has been developed. With explosive information on the Web 2.0, the Korean government has built the Human-Oriented Geographic Information System (HOGIS) in which Ontology was implemented for semantic query on the Web. On the government side, Korean government has produced various nationwide data through 4-phase NGIS project. Current NGIS ($4^{th}$ phase: 2011-2015) moves toward a Korean Green Geospatial Society using geospatial information as a new growth engine for the future.

Social Network Services are widely used by mass population and it is used as an important communications tool because it allows distribution of diverse and abundant amount of information. This thesis proposes to add a new valuable service function in social network for mobile-based civil complaint management. Therefore, we will develop a social network application for civil affair services that allows immediate civil compliant management while being able to share the contents related to civil affairs with other people. As a result of the experiment, the effect and efficiency of the method proposed in this thesis for social network-based civil affair services was proven. Hence, the social network for mobile-based civil affair services always provides new and improved service components. Moreover, discussing civil complaints in a social network point of view, we can expect high ripple effect and encourage more participation of public users dealing with civil affairs.

This study found the power analysis and increase plan of Smart work industry out. We did the internet survey with 117 experts of Smart work and analyzed International competitive power and Smart work marketability. The results was as follows: First, Experts recognized the growth about Cloud computing industry so that they were most high. Second, The thing which the earning of Smart work industry is high appeared a Security industry, Cloud computing industry, and Mobile office industry etc sequence. Third, The Smart work industry which an international technique power level is high appeared in a Smart e-learning industry, Mobile office industry, and Security industry etc sequence. Lastly, An Smart work industry which the concentration supports in the government dimension Security industry, Cloud computing industry, Smart work user SW industry, and Smart e-learning industry etc sequence. This research products will use for there even though it prepares a concentration support industry in the government dimension an activation policy.

As the hacking technology for cyber-terror and financial fraud evolves, the research and development for advanced and standardized information security technology is growing to be more and more important. In this paper, the domestic level of technology and standardization for information security as compared to advanced country is diagnosed, and future policy is presented by analyzing the influence effect for market and technology. The information security is classified into information security-based & user protection, network & system security, and application security & evaluation validation with details of OTP-based validation, smart-phone app security, and mobile electronic finance, etc. The analytic results indicate that domestic level is some poor for advanced country, the technological development and standardization capability for smart-phone app security and mobile electronic finance is needed, and finally the government's supporting policy for the future Internet is urgently needed.

As for civil service support, the interaction between citizens as well as the government and citizens has an important value, and the participation between citizens be very important. The interaction between these citizens can lead to spreading the use of the app by getting them to share their status information with an specified number of people in the public service such as a social network service. Mobile-based social network service has various built-in sensors to increase the interaction between the government and citizens and post the status information of users on SNS. In this regard, this paper proposed a social network application for civil services based on the Android by using location-based context information. Experimental results showed that since the application proposed in this paper can be applied to low-performance system and exhibits high performance, it can allow users located at a short distance to detect new information and share contents by adding the content to SNS which is the closest to the location of users.

In this study, we conducted a questionnaire survey for the purpose of finding a method of mobile sector ecosystem activation targeted at small and medium businesses (SMBs). Through the total of 204 responders consisting of business employees from each mobile sector, we analyzed the factors inhibiting the development of the mobile ecosystem and preventing the activation the mobile market, as well as conducting a diagnosis of the digital potential. This paper presented suggestions for searching for a systematic supporting strategy considering the short-term inhibitory factors (market structure improvement, financial support, etc.) and long-term orientation factors (personnel nurturing, strengthening of supporting role by governmental initiative) for the activation of the domestic mobile market. After measuring the digital potential, we found that domestic mobile SMBs have perceived the importance of the digital potential and have considered and readied themselves for the future market. The present survey found that if suitable digitalization can be accomplished for their firms' products and services, they have the ability and willingness to succeed in the market. However, they have a hard task ahead of them from adigital delivery perspective given the potential for digital disruptions.

스마트폰 보급은 현대인들에게 시간적, 공간적 제약에서 벗어나 언제 어디서나 무선 인터넷을 사용하여 모바일 뱅킹, 결재, 증권거래 등 원하는 서비스를 이용할 수 있게 해주었다. 사용자들은 이를 이용하여 다양한 정보들을 검색, 저장, 이용한다. 그러나 무선 인터넷의 순기능과는 반대로 최근 모바일 기기의 보안취약점을 이용한 악성애플리케이션 및 각종 공격으로 사용자 개인정보탈취의 위협이 증가하고 있다. 사회공학공격의 일종인 피싱(Phishing)은 신뢰받는 기관을 사칭하여 만들어놓은 가짜사이트에 사용자로부터 자신의 개인정보 및 금융정보를 입력하게끔 유도하여 사용자정보를 탈취하는 방법으로 최근 SMS를 이용하여 정부 및 금융기관을 사칭한 문자를 보내 피싱사이트로 접속을 유도하는 피해사례가 증가하고 있다. 본 논문에서는 국내 피싱사이트의 유형을 분석하고 피싱사이트로 접근을 유도하는 방법 중 하나인 SMS를 이용한 피싱을 방지 할 수 있는 시스템을 고안한다.
