정보통신 기술은 아날로그 산업에서 디지털 산업을 거쳐 현재는 스마트 산업으로 이어지는 수단으로 활용되어 왔다. 특히 산업 사회생활에서 문서로 직접 주고받던 환경에서 메일, 전자문서 교환 등으로 바뀌면서 편리성과 비용절감을 통해 산업 사회생활 발전에 기여하고 있다. 최근 빅데이터 기술은 대용량 정보를 분석하여 기상예측, 신약개발, 유전자 분석 등의 다양한 분야에 활용되고 있다. 그러나 대용량 정보 안에는 개인 식별을 할 수 있는 정보가 포함되어 있어, 빅데이터 기술을 바로 적용하기에는 개인정보보호법이 정하는 개인정보보호 이용에 관한 법률에 대한 준비가 미흡한 실정이다. 예를 들어 공공기관의 데이터를 활용하여 날씨 예측, 재난 방재 서비스 등을 통해 국민의 삶을 제고함과 동시에 경제적으로 많은 이익을 가져올 수 있다. 그러나 개인정보를 타인이 악의적으로 이용할 수 있어 개인에게 경제적, 정신적 피해를 줄 수 있다. 또한 개인정보의 노출은 과거와 달리 삭제되거나 잊혀지지 않고 영구적으로 재사용이 가능하기 때문에 이를 사전에 막을 수 있는 방법이 필요하다. 이에 본고는 빅데이터 등장에 따른 시장구조 변화 및 경제적 파급효과를 분석하고, 법리적 분석을 바탕으로 빅데이터 기술이 올바르게 시장에 정착할 수 있은 법(규제)방안을 제시하고자 한다.

Recently, digital music retrieval is using in many fields (Web portal. audio service site etc). In existing fields, Meta data of music are used for digital music retrieval. If Meta data are not right or do not exist, it is hard to get high accurate retrieval result. Contents based information retrieval that use music itself are researched for solving upper problem. In this paper, we propose Same music recognition method using similarity measurement. Feature data of digital music are extracted from waveform of music using Simplified MFCC (Mel Frequency Cepstral Coefficient). Similarity between digital music files are measured using DTW (Dynamic time Warping) that are used in Vision and Speech recognition fields. We success all of 500 times experiment in randomly collected 1000 songs from same genre for preying of proposed same music recognition method. 500 digital music were made by mixing different compressing codec and bit-rate from 60 digital audios.

The pinnacle of rapidly changing and advancing maritime transportation technology is expected to be the Maritime Autonomous Surface Ship (MASS). The implementation of various services within the MASS is likely to be feasible through the ship-centric network known as the S2X communication system. However, existing communication systems face issues such as service traffic saturation and failure to meet demanded functionalities, necessitating the proactive introduction of additional communication technologies. In this study, the concept of S2X communication for the MASS was redefined, deriving required functionalities and ultimately selecting frequencies suitable for utilization. Candidate frequency groups suitable for the derived communication requirements were identified, and communication frequencies prioritized for the initial application were chosen through expert consensus. It is anticipated that through further research, including experimentation to validate these frequencies, they could be utilized in implementing services for autonomous ship navigation in the future.

This study analyzes the characteristics of broadcasting law and telecommunication law and suggested the key legitimate of regulation where convergence law would go for in the convergence circumstances by drawing the common and differential characteristics of two laws. Moreover, in the value of inherent pursuit of broadcasting law and telecommunication law, this paper examined whether these values continued to be reflected in the convergence law, and indicated the direction how these values should adopt in the convergence law. The result of this study shows that strong entry regulation has applied to both broadcasting and telecommunications industry. Also, both industries have been required to be universal service to realize the value. Meanwhile, the pursuit of original value of broadcasting law and telecommunication law can be summarized as secure of access and diversity, respectively. In the convergence law, it is necessary to compensate and modify the meaning of access and diversity based on traditional regulation.

The purpose of this study is to investigate the influence of the social welfare service delivery system of Namyangju City on the satisfaction degree of the elderly with welfare services and on their quality of life. This study conducted a survey of the elderly aged 65 and over who were either service users or nonusers of the public-private partnership welfare service delivery system called Hope Care Center. A total of 324 copies including 205 copies of Hope Care Center users and 119 copies of nonusers were analyzed. The analysis shows that the four key elements of welfare service delivery system are statistically significant to the service users of Hope Care Center than the nonusers with the users' higher level of satisfaction with the services. However, in terms of quality of life, there was no meaningful distinction between the two groups. This indicates that services of Hope Care Center increased the satisfaction with welfare services, thereby improving users' quality of life to the level of nonusers. Further studies for the same subjects are expected to be deeper if they compare and analyze the before and after of using Hope Care Center with more comprehensive independent variables.

This study analyzed the level of digital informatization and the level of human relationship satisfaction in the disabled group. The digital informatization level of the disabled refers to the level of smart access, smart capability, and smart utilization. For the sampling of persons with disabilities, the survey was conducted for persons aged 7 to 69 who were registered under the Welfare for Persons with Disabilities Act. Regression analysis utilized SAS 9.3.s through vitalization of local communities, and information education for the disabled is also important. The analysis results are as follows. First, the higher the digital access level of the disabled, the higher the level of interpersonal satisfaction. Second, the higher the digital information capability level of the disabled, the higher the level of interpersonal satisfaction. Third, the higher the level of digital information utilization of the disabled, the higher the level of interpersonal satisfaction. As a result, the higher the digital information level of the disabled, the higher the satisfaction level in the interpersonal relationship of the disabled. In addition, it was found that careful attention and policy review are needed to resolve the digital information gap of the government for the disabled who are marginalized groups. Therefore, it is necessary to provide the expansion of universal services of the marginalized groups including the disabled. In addition, it is important to form a culture in which the community embraces the marginalized class through vitalization of local communities, and information education for the disabled is also important.

This paper defines markets relating to each paid broadcasting service by applying the test method of critical sales loss to the results of survey to the paid service subscribers. The result confirms the existence of a meaningful competitive relationship--in terms of the Competition Law--among all paid broadcasting services included in this study, or at least analog cable broadcasting, digital cable broadcasting, and real time IPTV(Internet Protocol TV) service. This indicates that current regulations which are being applied to cable TV, satellite broadcasting, and IPTV are actually discriminatory. Based on these analysis results, this paper suggests that the main attention for the improvement of regulations should be focused on regulations which are differently applied to different paid service providers. In particular, Article 20 in the Internet Multimedia Broadcasting Law is interpreted as defining the real-time IPTV as an independent market, thereby having leeway to harm fair competition among different paid service providers. Therefore, that article needs to change to give the right of equal access to contents to all the competing paid service providers. Furthermore, to put teeth in the contents equal access rule, most popular pay channels need to be designated as target contents of the rule. As for the market-share limitation regulations, the paper suggests that an upper limit on the market share should be set based on the total number of subscribers of all the competing paid services and the same limit applied to all the competing paid service providers.

Recently, there is a need to introduce a Korean-style restriction sandbox system that exempts or suspends existing regulations so that new products or services based on new technologies can be commercialized without restrictions. In response, the government reorganized the relevant statutes to promptly check regulations centering on four fields, including industrial convergence, ICT, FinTech, and regional innovation growth, and to allow experimental, proof and market releases by setting certain conditions(zone, period, scale, etc.). However, despite the same regulatory sandbox application, depending on the nature of the field applied, differences in application subject, whether application of regulatory specifics, system of push ahead decision-making and whether support of financial and taxation are shown. This research is intended to present efficient operation measures for successful settling of Korean-style regulation sandboxes by comparing and analyzing, centering on the Industrial Fusion Promotion Act in the Industrial Convergence Field, ICT field's Information and Communication Convergence Act, FinTech field's Financial Innovation Act and Regional Special Zone Act in the Regional Innovation and Growth Sector.
