본 논문에서는 XML Page로부터 닷넷 모바일 Web Page로의 변환 기능을 제공하는 웹서비스 프로바이더를 설계ㆍ구현하였다. 웹서비스 프로바이더는 플랫폼과 프로그래밍언어의 제약 없이 누구나 사용 가능하다는 장점을 가지고 있다. 본 논문에서 구현한 웹서비스 프로바이더로 제공하는 변환 라이브러리는 어휘분석기 모들과 구문 지향 번역기 모듈로 구성되어 있다. 어휘분석기 모들은 XML Page를 입력받아 각 태그들을 분석하고 토큰을 출력한다. 구문 지향 번역기 모듈은 어휘분석기에서 출력된 토큰들을 입력받아 문법을 체크하고, Parsing이 완료되면 대응되는 모바일 .NET 컨트롤로 변환하여 최종적인 닷넷 모바일 Web Page를 생성한다. 어휘분석기 모듈과 구문 지향 번역기 모들은 각각 어휘분석기 생성기(LEX)와 파서 생성기(YACC)를 사용하여 구현하였다. LEX와 YACC의 사용은 태그를 확장할 경우 변경된 부분만 설계함으로써 유연하게 대처할 수 있는 장점을 가지고 있다.

최근 GIS는 털러 분야에서 다양하게 운용되고 있다 최근에는 인터넷을 통한 정보 시스템의 요구가 급증하고 있으며, 웹 환경에서의 지리정보의 공유로 활용방안에 대한 연구가 활발히 이루어지고 있다. 특히, 지리정보의 활용을 위해 웹 지도 서비스의 요구가 증대되고 있다. 이를 위해 OGC(Open GIS Consortium)에서는 WMS(Web Map Service) 명세를 제시하고 있다. 그러나, 현재 제시되고 있는 WMS 명세만으로는 최근 발전하고 있는 모바일 환경에서의 적용이 어렵기 때문에 WMS의 인터페이스의 확장이 필요하다. WMS 확장을 위해 본 논문에서는 기존의 WMS를 분석하고 이를 바탕으로 모바일 환경에 적합한 WMS 확장 인터페이스의 방안을 제시한다. 또한, 확장 인터페이스를 바탕으로 모바일 환경을 위한 WMS 구조를 설계하고 개발한다. 본 논문에서 제안하는 WMS의 확장 인터페이스 및 이를 기반으로 하는 WMS 구조는 사용자들의 요구에 적합한 WMS 개발에 기초 자료로 사용될 것으로 기대된다.

다양한 크기의 모바일 기기가 등장함에 따라 기존 웹 어플리케이션으로는 개발자가 의도한대로 레이아웃을 구성하기 어려우며 네이티브 어플리케이션은 운영체제별로 각각 개발해야하기 때문에 많은 개발 시간을 필요로 한다는 단점이 있다. 본 논문에서는 부트스트랩을 이용하여 기기의 화면 크기에 가변적인 반응형 웹을 구축하고 모바일 운영체제의 웹뷰를 이용한 하이브리드 앱을 구현함으로써 개발과정 및 개발 시간 단축을 검증하였다.

With development of mobile communications terminal and expansion of mobile Internet, a large number of users can use mobile web contents at anytime and anywhere and will demand service of greater contents. Due to such demand, many studies are being carried out on transcoding contents so that wired web contents can be used in mobile web. However, transcoding and creation of mobile web contents involve difficulties because specifications available from telecommunications companies and mobile terminals have not been standardized. Especially, in order for serving dynamic object of wired web page contents to dynamically change according to time or user, it is required not only to program scripts to suit each terminal, but also to transcode the resources used in advance. for solution to this problem, this study uses the hierarchy structure of DOM (document object model) to display structural characteristics of wired web page. In other words, this study proposes the following technique. Wired web pages are analyzed and the results are established as data structure. Then, dynamic object is extracted and the domain is indexed so that, when serving mobile web page, information can be extracted at the indexed position to create mobile web contents for service on real-time basis. Also, this study aims at developing an editing device to edit mobile web contents and mobile web service server to service the edited contents by applying the above technique.

As a recent dominant web trend, mobile first strategy has been emphasized, and interests with respect to responsive web that provides effective methodology to various mobile devices and their display resolution are also increasing. However, it is an early adoption stage in web mapping for geo-spatial applications. This study is to present some practical examples of layouts using responsive web technologies linked to geo-spatial open platform. Suggestive consideration points for further application of responsive web to geo-spatial services are presented. On test implementing, HTML5, JavaScript, and CSS3 were used, and web mapping processing using OpenLayers was performed. It is expected that responsive web applications for contents derived from geo-spatial information or location data increase.

Recently new web trends and mobile technologies are expanding and developing so fast. To improve the implementation efficiency of information systems, eGovernment standard framework has been developed and distributed. Recently, eGovernment standard framework for mobile environment was further developed. In addition, many types of public data produced by public organizations supported by government are being opened through public data portal according to Government 3.0 policy. Demands regarding web standards and common framework usages for mobile application development in most business fields dealing with any types of contents are increasing. However, to link those things to geo-spatial data or integrate those with them are an early stage in the geo-spatial application field, compared to other application fields. Based on these backgrounds, a mobile web application system was designed and implemented to present visualization functionalities of public data and geo-spatial data using HTML5 components under mobile operation environment in eGovernment standard framework in this study. It is expected that this system can be applied to develop many mobile application business models, by the further works such as application of core developing environment in eGovernment standard framework, additional functionalities, and high performance to satisfy with user requirements for a certain target application.

For the past few years, unlike wireless widespread United States and Japan, expensive cost and platform of the mobile web carrier underground and self-centered made achievement of domestic mobile web market sluggish. Nowadays, more and more people pay attention to the mobile web service because of the increased quality of wireless internet, development of mobile device and variety of the flat-rate payment system. However, another big problem is that mobile web is too hard to use. Also, the poor content of mobile web service is an extremely serious problem. In this paper, we put forward a new method for easy to access mobile web service which is use WINC expansion numbers and users can use these numbers to shit their own website. Along with the benefits of purchase WINC number general users are able to make website and control their website at less time and energy.

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.

Many businesses, government offices, educational institutions, according to the characteristics of each business and information system is used. However, prevalence of smart phones and a wide range of mobile devices with services, which requires users with mobility, according to the latest mobile services and in many places, and is under development. Interworking between existing systems and mobile systems to be set aside for the development cost and time, a waste of human resources is getting worse. Also, in many places to provide mobile services to existing systems need to fix the problem is coming. In this paper, to solve the problem of interworking between existing systems and mobile systems for the data transfer and processing of existing server, web services server, and mobile systems has been developed between the library.
