모바일 시장의 급경한 성장세와 기존의 복잡한 결제방식 절차 간소화에 대한 사용자 요구의 증가는 ICT 기반 금융산업에서 최신 기술과 융합된 핀테크 기술을 등장시켰다. 핀테크에 대한 관심도가 높아짐에 따라 핀테크 기업에 대한 투자규모, 핀테크 기업 수, 핀테크를 기반으로 한 모바일 결제의 세계시장 규모가 빠른 속도로 증가하고 있다. 이에 핀테크 기업이 서비스를 함에 있어서 하나의 운영 요소로 취급되던 보안 기능이 보안을 위한 처리 기술 자체로 하나의 서비스 유형으로 부각되기 시작했으며, 핀테크 내 보안 분야에 대한 시장규모의 비중, 업체 수는 꾸준히 증가할 것으로 보인다. 본 논문은 이러한 추세에 맞춰 핀테크 보안에 대한 기술로드맵을 수립하여 기술의 추세를 전망하였으며 시장 추이 분석을 하였다.

This paper proposes an R&D opportunity scan framework for information and telecommunications company in aging society. The framework consists of trend analysis, market-oriented search, technology-oriented search, and R&D Portfolio development. We identify technology themes in the market-oriented search by developing market scenarios and analyzing a new business model framework. And then we search prospective technologies in the technology-oriented recess by technology scanning and patent analysis. By matching technology themes with prospective technologies, generate an R&D portfolio. Finally, we evaluate the risk of the proposed R&D portfolio.

이차전지의 응용영역이 소형시장 중심에서 향후 대형 시장으로 확대될 것으로 예상되며, 한국, 일본, 중국, 미국 등을 중심으로 시장이 형성될 전망이다. 본 연구에서는 이차전지의 특허 정보를 이용하여 현재 우리나라의 기술적 위치를 파악하고 IPC 정보를 이용하여, 기술 분야 간 관계를 규명하여 향후 이차전지 분야에서의 기술 개발 방향에 대해 제시하고자 하였다. 그 결과 한국은 현재 이차전지 시장에서 기술적으로 비교적 우위를 점하고 있지만, 전기 자동차 등 중대형 이차전지 분야에 대한 기술 개발이 상대적으로 미흡하여 이에 대한 많은 연구가 필요하다고 판단된다.

Purpose: Transcatheter device closure of patent ductus arteriosus (PDA) is challenging in early infancy. We evaluated PDA closure in infants less than 6 months old. Methods: We performed a retrospective review of infants less than 6 months of age who underwent attempted transcatheter device closure in our institution since 2004. To compare clinical outcomes between age groups, infants aged 6-12 months in the same study period were reviewed. Results: A total of 22 patients underwent transcatheter PDA closure during the study period. Patient mean age was $3.3{\pm}1.5months$, and weight was $5.7{\pm}1.3kg$. The duct diameter at the narrowest point was $3.0{\pm}0.8mm$ as measured by angiography. The most common duct type was C in the Krichenko classification. Procedural success was achieved in 19 patients (86.3%). Major complications occurred in 5 patients (22.7%), including device embolization (n=1), acquired aortic coarctation (n=2), access-related vascular injury requiring surgery (n=1), and acute deterioration requiring intubation during the procedure (n=1). Two patients had minor complications (9.1%). Twenty-four infants aged 6-12 months received transcatheter device closure. The procedural success rate was 100%, and there were no major complications. The major complication rate was significantly higher in the group less than 6 months of age (P=0.045). There was a trend toward increased major complication and procedural failure rates in the younger age group (P<0.01). Conclusion: A relatively higher incidence of major complications was observed in infants less than 6 months of age. The decision regarding treatment modality should be individualized.

Approximately 8.5 million tons of fly ash and 740,000 tons of briquette ash were produced in 2010. Inefficient recycling of coal ash has been a heavy economic and environmental burden and economical coal ash utilization technologies are required to turn coal ash into valuable resources. In this study the patents and literature were analyzed to understand the present situation of coal ash recycling technologies and to promote utilization of coal ash for producing a non-sintering green cement, geopolymer. The survey was based on the open patents of USA, European Union, Japan and Korea, and the papers in SCI - indexed journals published between 1979 and 2013. Technical key words were used for data collection and noise filtering. Trends of recycling technologies in utilization of coal ash for producing geopolymers were discussed in terms of time periods, countries, companies and various forms of technologies.

Electronic products such as appliances, computers, and cellular phones have printed circuit boards (PCBs) in common and the PCBs in the waste electronic products contain valuable metals and organic resins. In Korea, recovery and recycling of the organic resins as well as the valuable metallics from the wastes are required indeed as the most of resources are being imported from abroad. In this article, the patents and papers for the recycling of organic residues from the waste PCBs were collected and analyzed. The open patents of USA (US), European Union (EP), Japan (JP), and Korea (KR) and SCI journals from 1979 to 2012 were investigated. The patents and journals were collected using key-words and filtered by the definition of the technology. The patents and journals were analyzed by the years, countries, companies, and technologies and the technical trends were discussed in this paper. It is showed sluggish relatively activity of published papers and patent applications for polymer manufacturing technology in local and abroad.

In this paper the world wide patents on the recycling of used batteries were inspected. The trend and direction of on-going and future technologies on this matter were analyzed. The range of search was limited in the open patents and in DB of U.S.A.(USPTO, DLPHION), Japan(PAJ), Europe(EPO), and Korea(KIPRIS). For the search condition the keyword, battery, batteries, electric cell, patent, and recycling, and IPC classification were used. The total of 2,490 cases was found at the first search stage, then, through the 2 steps of filtering processes the total of 871 cases was selected for the final analysis. These 871 cases were classified by countries, companies, and technologies between the year 1971 and the you 2000.

Global climate change and urbanization have various demerits, such as water pollution, flood damage, and deterioration of water circulation. Thus, attention is drawn to Nature-based Solution (NbS) that solve environmental problems in ways that imitate nature. Among the NbS, urban wetlands are facilities that perform functions, such as removing pollutants from a city, improving water circulation, and providing ecological habitats, by strengthening original natural wetland pillars. Frequent monitoring and maintenance are essential for urban wetlands to maintain their performance; therefore, there is a need to apply the Internet of Things (IoT) technology to wetland monitoring. Therefore, in this study, we attempted to develop a real-time wetland monitoring device and interface. Temperature, water temperature, humidity, soil humidity, PM1, PM2.5, and PM10 were measured, and the measurements were taken at 10-minute intervals for three days in both indoor and wetland. Sensors suitable for conditions that needed to be measured and an Arduino MEGA 2560 were connected to enable sensing, and communication modules were connected to transmit data to real-time databases. The transmitted data were displayed on a developed web page. The data measured to verify the monitoring device were compared with data from the Korea meteorological administration and the Korea environment corporation, and the output and upward or downward trend were similar. Moreover, findings from a related patent search indicated that there are a minimal number of instances where information and communication technology (ICT) has been applied in wetland contexts. Hence, it is essential to consider further research, development, and implementation of ICT to address this gap. The results of this study could be the basis for time-series data analysis research using automation, machine learning, or deep learning in urban wetland maintenance.
