In this study, de-identification policies of the US, the UK, Japan, China and Korea are compared to suggest a future direction of de-identification regulations and a method for vitalizing the big data industry. Efficiently using the de-identification technology and the standard of adequacy evaluation contributes to using personal information for the industry to develop services and technology while not violating the right of private lives and avoiding the restrictions specified in the Personal Information Protection Act. As a counteraction, the re-identification issue may occur, for re-identifying each person as a de-identified data collection. From the perspective of business, it is necessary to mitigate schemes for discarding some regulations and using big data, and also necessary to strengthen security and refine regulations from the perspective of information security.

According to continuous development of information technology, it is needed to make convergence of other disciplines such as humanities and area studies. Among convergence fields related to information technology and humanities/area studies, electronic cultural atlas represents various digitalized cultural information on electronic map using spatial data such as points, lines, and polygons through time, spatial, and subject axises. Knowledge map is to represent special academic information based on electronic cultural atlas. In details, knowledge map can provide integrated information sharing and spread because academic information associated with electronic cultural atlas and data related to per subjects, regions, and period become organically connected. Therefore, knowledge map may be utilized to promote scholastic research and diffuse research result. In this paper, we describe basic concept and composition of knowledge map and propose design method to construct knowledge map.

The development focus of a smart city has been changed gradually from a physical development aspect to a space development aspect. In a space development aspect, the major application technologies are Environment Technology (ET), Information Technology (IT) and Environment Information Technology. On the other hand, it is unclear if the space convergence in a smart city has been changed by the 3 technologies. Therefore, specific analysis was performed on the convergence change of smart city 4 spaces (District, Street, Building, Facility) using the 3 technologies. The convergence distribution ratio according to the periods (period 1 : 1972~1999, period 2 : 2000~2009, period 3 : 2010~2017) among the spaces, ET (Environment Technology), IT (Information Technology), ET+IT (Environment Information Technology) in a smart city were examined. The smart city was high in the order of 'District (53/43%) - Building (36/29.1%) - Street (22/17.9%) - Facility (12/10.0%)' in the number of applications and ratio of convergence (Technology Convergence) at Period 1 (1972~1999). The smart city was high in the order of 'District (223/32.4%) - Building (197/28.6%) - Street (195/28.3%) - Facility (74/14.8%)' in the number of applications and ratio of convergence (Technology Convergence) at Period 2 (2000~2009). At period 3, the District (467/33%) was also the highest. On the other hand, the street (384/27.4%) was higher than the building (361/25.8%) and facility (188/13.4%) in smart city space. Fourth, the smart city was high in the order of 'District - Building - Street - Facility' in the number of applications and ratio of convergence (Technology Convergence) at Periods 1 (1972~1999) and 2 (2000~2009). In contrast, the average of number was high in the order of 'Building - Street - District - Facility'. At period 3(2010~2017), the number of applications and the ratio of convergence was high 'District - Street - Building - Facility'; the average of number was the same as in period 1 and 2. As a result, smart city space has been changed by the development of macroscopic urban spaces in the initial stage. Since then, district space-centric development and building space are confused with devices/technologies and changed for citizen inflow. The building space has evolved continually and smart city space will be expected to revitalize the street space connecting completed buildings.

Today, home gardening is in the spotlight. Therefore, the necessity of developing a new type of gardening product was raised according to the consumer's desires. This study, the contents were developed using sparrows, a helper who helped the bean rat's grain-cracking task among the characters of 'kongjwi patjwi'. The cultural contents convergence product is a lid production that is used at the end of the plant support. The fabrication method was designed using UG NX program after design research, and after printing by 3D polyjet method, mold was made and cast into silicon and resin. Through product manufacturing, we could confirm the public's interest in the possibility of new products and creativity. In the future, it is expected that the development of products incorporating cultural contents through various cultural archetypes will be activated, contributing to the enhancement of economic added value and national brand value.

Our society, which has arrived in the 4th industrial revolution, emphasizes covergence education to cultivate creative convergence talents. Therefore, this study is to develop a convergence education program consistent with the direction of the 2019 revised Nuri course and to help teachers who want to implement convergence education. In order to achieve this purpose, in this study, voluntary questions that occurred in play using the educational robot 'Turtle' were classified as STEAM elements. After that, frequency analysis and correlation analysis were conducted. Therefore, this study is meaningful in collecting children's questions about the same robot by age, and it is valuable in establishing future convergence education directions by analyzing the correlation by STEAM elements.

Currently, our country has promoted sustainable growth in agriculture field by expanding the growth engine which is going to creat new value through agrifood industry & ICT convergence, the deployment of computerization in rural areas and the efficiency increase of agricultural administration system. Since the level of domestic agriculture-ICT convergence technology focusing on production areas is at early stage, it is necessary to deploy the successful models through the systematic development of technology and standardization including production, distribution and consumption phase. In addition, because the management and control systems of large glass greenhouse are mostly foreign products with no standardization and related small domestic companies, there is a limit to agri-food & ICT convergence activation led by the agri-food private sector. Also, it is vital to increase productivity & efficiency and improve quality throughout the entire agricultural process including production, distribution and consumption by the fusion of information technology, automatic control technology and unique ICT on existing agricultural technology, Therefore, in this paper we propose the agricultural-ICT convergence technology fields in which our country can lead technology and the standardization plans through analyzing the development, policy and standardization trends on agricultural-ICT convergence technology.

최근 스마트 기기는 결제, 할인쿠폰 등 각종 기능을 제공하는 수단으로 진화되면서 통신과 금융이 융합된 모바일 NFC 서비스의 시장이 급성장할 것으로 전망되고 있다. 특히 모바일 NFC 결제 서비스 시장의 활성화가 예상됨에 따라 모바일 NFC 결제 서비스는 국내 외적으로 널리 주목받고 있다. 하지만 이를 주도할 수 있는 보안 관련 기술력이 부족한 상태이며 NFC 모바일 결제 환경에서 적용이 가능한 NFC 결제 관련 기술 연구도 미흡한 실정이다. 이에 따라 기존 방식과는 전혀 다른 결제 환경과 결제 방식에 의해 도출될 수 있는 다양한 응용서비스에 대한 새로운 법 제도의 정비와 새로운 결제환경에 맞는 보안기술이 필요할 것으로 예상된다. 본 논문에서는 기존의 물리적인 플라스틱 신용카드의 권한 위임 문제와 NFC 모바일 신용카드를 비교하여 NFC 모바일 기반 결제 서비스 상에서의 위협을 분석하고 NFC 결제환경에서 안전한 결제 권한 위임이 가능한 Hash Chain기반의 Time-Stamping Proxy 서명 기술을 제안하였다.
