We face many fascinating and diverse challenges, the most important among which is to determine how to store a large amount of information with novel approaches. Info-convergence ceramic nanosystems, which combine ceramic materials science and information technology, may provide an attractive alternative. This review considers recent multidisciplinary advances in the development of info-convergence nanosystems based on ceramic materials and discusses various strategies under ceramic-based information systems with a special focus on materials and nanohybridization technologies. Ceramic materials have played diverse roles not only as the generic coding support, but also as the central coding substance. The review highlights the ceramic nanohybrid bio code and ceramic nanoparticle optical code for applications in tracking-and-traceability management, nano-forensics, anti-counterfeiting, and even communication, as well as the four steps of encoding, encrypting, decrypting, and decoding for the desired applications. Additionally, associated challenges, potential solutions, and perspectives for future developments in the field are discussed.

Whole genome sequence of Abeliophyllum distichum Nakai (Oleaceae) cultivar Ok Hwang 1 Ho, which is Korean endemic species, was recently sequenced to understand its characteristics. Acteoside is one of major useful compounds presenting various activities, and its several proposed biochemical pathways were reviewed and integrated to make precise biochemical pathway. Utilizing MetaPre-AI^TM which was developed for predicting secondary metabolites based on whole genome with the precise biochemical pathway of acteoside and the InfoBoss Pathway Database, we successfully rescued all enzymes involved in this pathway from the genome sequences, presenting that A. distichum cultivar Ok Hwang 1 Ho may produce acteoside. High-performance liquid chromatography result displayed that callus of A. distichum cultivar Ok Hwang 1 Ho contained acteoside as well as isoacteoside which may be derived from acteoside. Taken together, we successfully showed that MetaPre-AI^TM can predict secondary metabolite from plant whole genomes. In addition, this method will be efficient to predict secondary metabolites of many plant species because DNA can be analyzed more stability than chemical compounds.

With the rapid development trend in multidisciplinary science and convergence technology, digital data storages have been necessary in order to accumulate a huge amount of information with high security. The possibility that biological DNA code system can offer encoding and decoding information has been illustrated by many researchers. In this review, we summarized current issue of info-convergence nanohybrid system, so-called infohybrid. DNA-inorganic nanohybrid materials and devices to achieve DNA-based molecular information system are presented. The possible applications focusing on tracking-and-traceability management, authenticity verification, and nano-forensics are also reviewed with four steps of encoding, encrypting, decrypting and decoding. We also highlighted the potential of smart code system with Nano-Bio-Info-Cogno (NBIC) convergence technology through the recently published case study of Avatar DNA nanohybrid system with smart phone.

인터넷 기술의 발전과 웹 사용자의 증가로 웹에는 매우 않은 정보들이 축적되고 있으며, 여기에는 또한 매우 많은 지역정보가 존재한다. 일반적으로 웹 정보라고 하는 것은 웹의 컨텐츠, 사용이력, 구조를 중심으로 한 정보이며, 이러한 정보를 하나의 중요한 공간 정보원으로 취급하여 웹으로부터 특정 지역에 관한 컨텐츠를 수집하고 이를 분석하여 사용자의 공간 정보원으로서 사용할 수 있다. 또한 인터넷, 무선통신, 지리정보시스템(GIS), 위치기반서비스(LBS) 등의 기술들이 모바일기기에 복합적으로 접목되면서 모바일기기에서의 새로운 형태의 정보에 대한 응용이 요구되고 있다. 본 논문에서는 이러한 웹 환경을 활용하고, 모바일 환경을 고려하여 GIS와 Web을 통합한 모바일 지역정보 검색 시스템을 제안한다.

With the development of economy, people's self-interest about one's appearance has been increasing. Among them, especially interest in women's fashion is increasing very. By increasing interest of women's appearance, requirements of various women's fashion marketing ways are increasing and the women's fashion market is expanding as much as it is. Therefore, in this paper, we propose the strategies for marketing activation in women's fashion after consideration of general women's fashion marketing strategies. Through the activation of the marketing strategies, marketing in a women's fashion market is expected to be competitive.

In this paper, we introduce InfoDID, a robust user information management service based on DID that manages user information reliably. Since blockchain technology provides an environment in which data can be handled transparently on a decentralized basis, various services using blockchain are currently being developed As the importance of user's personal information has recently emerged, the DID technology is receiving attention. The technology allows a user to control his or her information through decentralized identifiers, and various information management services are being tried based on the technology. Using blockchain-based DID technology, InfoDID reliably controls personal information requested frequently, helping users to provide their information to other services more conveniently. In addition, to support service continuity, InfoDID uses BR2K technique that provides robust execution of blockchain application services, so that even partial service failures can be systematically recovered. To facilitate this operation, we present a replication status monitoring tool that can continuously check the replication states of blockchain application services running in association with the BR2K technique such as InfoDID.
