"Information", which is circulated in society by information technology development represented by computer, has brought innovation not only to physical civilization, but also deep into our daily lives. This is to say that information has brought fundamental change to its form of existence, and value system through being faster regarding the circulation and the way of management being diverse. As time goes by, this kind of change would stimulate more changes to be made as the development of scientific civilization. Therefore, informatization is one of the important characteristic that defines modern society's essence, but on the other side, information has been taken advantage of that temperament and abused in a lot of different ways. "The Law Regarding Computer Network Diffusion Expansion and Usage Promotion"(1986), as a counterplan of informatization is our nation's first Act about informatization, which enacts national policy and system about this issue. Since then, many laws has been enacted down to "Private Information Protection Act"(2011), forming a comprehensive system. The basic background of these laws are based upon the premise that even if the place where the information is managed is virtual space, rules that are considered valid in the real world should be basically applied in the virtual space. Therefore, the violation of the law in the real world is also considered the violation in the virtual space. This direction of current law regarding information is shared with both the theories and the reality. However, current law system and notion are based upon the premise that the law regards material objects, thus the characteristic of the information, which is "Immaterial Being" is not reflected. Also, the management and approach to this issue is allopathic, exposing many problems. Thus, this paper examines the way of protecting information stipulated in the current law, contemplates its protection scope and limitation, and seeks the direction of the improvement, based on the critical mind explained above.

This thesis analyzes the Apple Inc.'s case from the viewpoint of the necessity for the protection of information privacy related to location data as for information society and ubiquitous community. Meanwhile, the regulatory conformity to equilibrium of contradictional value between personal data protection and utilization of information is debated from the fundamental right as for constitutional law concept to the commercial and technological structure in terms of economic and business point. Therefore, this paper reaches the conclusion that the legislative system should form a harmonious relationship between legal protection and lawful utilization to reappraise the present condition of legalization on personal data protection from guaranteeing rights and interests of information subject in the perspective of human rights to information guarantee consequently. As a result, it is required to revaluate the lawfulness of the fine on the violation of administrative duty levied by KCC(Korea Communications Commission).

1950-1960 년대의 녹색혁명은 1970년 Nobel 평화상수 상자 Norman Borlaug가 주도했었다. 제1 녹색혁명은 지구상의 가장 큰 문제점중의 하나인 기아를 해결하는지 크게 일조하였다. 많은 사람들을 굶주림으로부터 해방시켰지만 굶주리는 사람보다 더 많은 사람들이 매일 태어나고 있고, 지구의 인구증가는 지금까지 계속되고 있다. 언제까지 인구증가가 계속될 것인지, 인구증가에 따른 식량자원의 증가도 비례할 것인지는 오래전부터 인류의 관심의 대상이 되어 왔고, 자연스럽게 지구의 기아를 해결하는 제2의 녹색혁명은 과학자들의 연구를 집중시키는 결과를 낳게 되었다. 1980 년대에 미국 Monsanto 회사에서 유전공학적으로 개발한 Roundup-Ready 제초제저항성 및 Bt-살충 농작물을 선보이면서 제2의 녹색혁명이 시작되었다고 볼 수 있겠다. 이렇게 제2의 녹색혁명은 유전공학에 의한 CMO 식물$\cdot$작물에 의해 시작되었다. Monsanto 회사는 살충제 RoundUp 제초제 저항성 옥수수, 콩, 목화, Canola (유채꽃, rape seed) 등을 개발하여 이미 상업화하였다. 1960년대 쌀의 녹색혁명도 유전적으로 벼집이 짧은 품종에 의해 이루어졌다. 최근에 개발된 GMO "Golden Rice"는 비타민 A와 철분의 함량을 대폭 증대 시켜 세계 영양결핍 아동들의 건강과 시각을 향상시킬 것으로 기대되는데, "Golden Rice"는 제1회 금호국제과학상 수상자인 Potrykus (스위스공대) 교수가 개발하였다. 그러나 현재까지는 그 보급에 많은 장애물이 있다. 특히 GMO의 환경과 건강에 대한 안전성을 의심하는 사람들이 많다. 제2의 녹색혁명의 또 다른 분야는 식물의약 분야이다. GMO 개발에 적용되는 기술을 이용하면 taxol 같은 항암제, carotene 같은 항산화 영양제 등의 대량 생산이 가능해진다. 식물은 화학적 합성이 아주 까다로운 약제물질 등을 천연상태에서 합성하고 있기 때문이다. 또 식물은 lipoxygenase 효소계가 있어서 마치 천연물 석유제조공장과 같은 제조공정 capacity를 가지고 있다. 그러면 식물/식품 GMO는 안전한 것인가? 아니, KBS의 한 사회자가 말했듯이, 그리고 많은 소비자들이 믿는 것처럼 GMO는 위험한가? GMO에 대한 일반 사람들의 공포감은 Green Peace 당원들뿐만 아니라 일부 과학자들에 의해서도 조장되고 있다. 이러한 분위기 속에서 GMO에 의한 제2 녹색혁명은 Africa 대륙에서의 제1 녹색혁명이 지금도 지연되는 것과 같다고도 볼 수 있다. GMO의 환경에 대한 악영향은 과대 선전되어있는 것이 아닌가? 마치 GMO가 화학비료, 농약제보다 더 위험하다고 믿는 사람들도 많다. 나는 이러한 GMO 공포증이 과학적으로 그리고 "Risk Assessment"의 견지에서 볼 때 그 근거가 희박하다고 보여주는 몇 몇 실험 및 경험 사실들을 인용하려 한다. 그리고 올바른 Risk Assessment야 말로 한국의 21세기 BT 산업을 경쟁력 있게 하고 국민 년 소득 2만불 달성에 중요한 기여를 하게 될 것이라고 생각한다. 한국은 농토가 적고 천연자원이 빈약하다. GMO는 21세기의 생존 경쟁 산업이다. 제2의 녹색혁명은 얼마든지 가능하며, 한국은 부족한 농토와 빈약한 자원에도 불구하고 능력 있는 인적자원이 풍부하여 GMO 개발 연구에 국제적 경쟁력을 키울 수 있다. 그러나 GMO에 대한 논쟁만 하고 있으면 이미 때가 늦는다. 미국은 이미 GMO-BT 시장을 거의 완전 독점했으며, 타국에서의 논쟁과 불합리적으로 엄격한 GMO 관련 규정을 조장하고 환영한다.

The popularity of smart devices and Location Based Services (LBSes) is increasing in part due to users demand for personalized information associated with their location. These services provide intuitive and realistic information by adopting Augmented Reality (AR) technology. This technology utilizes various sensors embedded in the mobile devices. However, these services have inherent problems due to the devices small screen size and the complexity of the real world environment; overlapping content on a small screen and placing icons without considering the user's possible movement. In order to solve these problems, this paper proposes a Mobile Augmented Reality Model with the application of Street Data. The model consists of two layers: "Real Space" and "Information Space". In the model, a user creates a query by scanning the nearby street with a camera in real space and searches accessible content along the street through the use of the information space. Furthermore, the results are placed on both sides of the street to solve the issue of Overlapping. Also, the proposed model is implemented for region "Aenigol", and the efficiency and usefulness of the model are verified.

With the increasing use of high-performance mobile devices such as smartphones, users have been able to connect to the Internet anywhere, anytime, so that Location Based Services(LBSes) have been popular among the users in order to obtain personalized information associated with their locations. The services have advanced to provide the information realistically and intuitively by adopting Augmented Reality(AR) technology, where the technology utilizes various sensors embedded in the mobile devices. However, the services have inherent problems due to the small screen size of the mobile devices and the complexity of the real world environment. Overlapping contents on a small screen and user's possible movement should be taken into consideration in displaying the icons on objects that block user's environment such as trees and buildings. The problems mainly happen when the services use only user's location and sensor data to calculate the position of the displayed information. In order to solve the problems, this paper proposes a method that applies street data extracted from a digital map. The method uses the street data as well as the location and direction data to determine contents that are placed on both sides of a virtual street which augments the real street. With scrolling the virtual street, which means a virtual movement, some information far away from the location of the user can be identified without user's actual movement. Also the proposed method is implemented for region "Aenigol", and the efficiency and usefulness of the method is verified.

A braille library undoubtedly changes with a changing information environment. However "changing information service" as a topic couldn't be found among previous researches. That's the reason it felt necessary in this paper to analyze the way service in a braille library changes according to a changing environment. as well as to make clear the meaning and the role a braille library has for blind people. As a first step, a questionnaire aimed at Korean braille libraries was carried out in order to understand changes of library service. Results showed that most changes in braille library service were due to the influence of internet, directly or indirectly. In this connection. the way braille libraries made us of this new tool was analyzed as follows. Firstly braille libraries were found to help a better circulation of information from internet towards blind people. It appeared secondly that internet was also used in order to improve already existing services as well as new services. Thirdly libraries were shown to have developed new services related to internet although these services weren't initially library ones. These new aspects of library service constitute by themselves a proof of the importance of braille libraries, although blind people might in some cases obtain the wished piece of information without them. Therefore braille libraries prove to be remained necessarily even if information environment changes.t changes.

With the spread of wireless internet, the interest in mobile applications and services is increasing. Korea Wireless Internet Standardization Forum has been establishing the standards for mobile platform and map service in the wireless internet environment. This study aims to present a paragon of mapping middleware that plays the role of broker for wireless internet map service: in particular, it focuses on the interoperability with generic map servers. In this study, we developed a method for applying current map servers to the wireless internet map service, and analyzed the request/response structure of the map servers which have different operation characteristics in order to allow our middleware to fully utilize the functionalities of the map servers. The middleware we developed is composed of .NET-based XML Web Services: it has a lightweight module for image map and a map representation module for choropleth map, symbol map, chart map, etc. This mapping middleware is a broker between mobile client and generic map server, and supports .NET clients and Java clients as well. Its component-based interoperability grants the extensibility for the wireless internet dedicated map servers of the future in addition to the current generic map servers.
