Apple's iPhone was released and the SmartPhone craze started in the world. Then, Many kind of SmartPhone released on the market, the number of subscribers increased explosively for the convenience of SmartPhone. By SmartPhone users increases rapidly, the number of Malware targeting SmartPhones increased explosively. The SmartPhone Malware, tend to increase explosively in 2012 beginning to be discovered in earnest from the second half of 2011, and is continuously increasing even now. In this paper, describes the status and trends of SmartPhone Malware, through the analysis of trends in the SmartPhone Malware, we describe the future prospects of SmartPhone Malware.

Distributed Ledger Technology (DLT) refers to a process and related technologies that enable a person to safely suggest, verify, and record state changes (usually updates) to synchronize ledgers distributed across network nodes. DLTs are becoming increasingly important as data management requirements evolve. Therefore, they need to understand the current state of standards (such as distributed storage and access technologies) to address future requirements. This paper provides ITU-T FG-DLT standard activities, such as standardization ization trends, use cases, reference architectures, platform evaluation criteria and future prospects.

The Switched Reluctance Motor(SRM) drive system could operate in a very wide speed range with high efficiency There are no windings, no magnet and a brushless structure on the rotor, and there is only multi-phase centralized windings on the stator, those give rise to its simple and firm structure. It has good Prospects for application. such as industrial and home appliance. in aircraft. This paper is to show a development trends in SRM technology.

인터넷 접속료 정산방식은 그동안 피어링과 트랜짓 모델이 주로 활용되어 왔으나 인터넷 트래픽의 폭발적 증가, OTT 서비스 확산 등으로 망 이용대가의 적정 분담을 위해 발신자지불방식(SPNP: Send Party network Pay) 등 새로운 정산모델 도입이 필요하다는 주장도 제기되고 있다. 본고에서는 인터넷 접속료 정산방식으로 활용되어 온 피어링과 트랜짓 정산모델의 특징과 도입배경, 다양한 피어링/트랜짓 변형 모델을 살펴보고, 최근 유렵 통신사업자 협회가 제안한 발신자지불방식 정산모델의 제안 배경 및 ITU, OECD 등 국제기구에서의 논의 동향을 검토해보고자 한다.

The reverse electrodialysis (RED) is an energy generation system to convert chemical potential of saline water directly into electric energy via the combination of current derived from a redox couple electrolyte and ionic potential obtained when cation ($Na^+$) and anion ($Cl^-$) pass through cation exchange membrane (CEM) and anion exchange membrane (AEM) into fresh water, respectively. Ion exchange membrane, a key element of RED system, should satisfy requirements such as 1) low swelling behavior, 2) a certain level of ion exchange capacity, 3) high ion conductivity, and 4) high perm-selectivity to achieve high power density. In this paper, research trends and prospects of ionomer materials and ion exchange membranes are dealt with.
