In this paper, we propose a design and implementation method of speed quiz content that can be driven by a social robot capable of interacting with humans, and a method of developing an intelligent module necessary for implementation. In addition, we propose a method of implementing speed quiz content through the process of constructing a map by arranging and connecting intelligent module blocks. Recently, software education has become mandatory and interest in programming is increasing. However, programming is difficult for students without basic knowledge of programming languages to directly access, and interest in block-type programming platforms suitable for beginners is growing. The block-type programming platform used in this paper is a platform that supports immediate and intuitive programming by supporting interactions between humans and robots. In this paper, the intelligent module implemented for the speed quiz content was used by blocking it within a block-type programming platform. In order to implement the scenario of the speed quiz content proposed in this paper, we implement a total of three image-based artificial intelligence modules. In addition to the intelligent module, various functional blocks were placed to implement the speed quiz content. In this paper, we propose a method of designing a speed quiz content scenario and a method of implementing an intelligent module for speed quiz content.

EDMS systems have been a main alternative for enterprise content management (ECM), which provide valuable functions for the effective control and management of organization-level digital contents. However, it has not been effective frequently for the purpose of integrative control of overall contents in an organization. One of reasons for this problem is that individuals usually create and store files with their own personal computers and do not move them to the central storage and control device, EDMS. Many occasions show that this situation can cause undesirable results for better management of enterprise contents. This paper introduced an approach of virtual folder which can directly connect individual computers and EDMS storage device without users' inconvenience. Adding the capacity of restricting usage of individual computer, users unavoidably and conveniently store and retrieve digital contents using EDMS server system. Several modules and implementing architecture for the virtual folder system are shown and the results of utilizing the system are explained with a case of application.

A temperate phage was isolated from emetic Bacillus cereus NCTC 11143 by mitomycin C and characterized by transmission electron microscopy and DNA and protein analyses. Whole genome sequencing of Bacillus phage 11143 was performed by GS-FLX. The phage has a dsDNA genome of 39,077 bp and a 35% G+C content. Bioinformatic analysis of the phage genome revealed 49 putative ORFs involved in replication, morphogenesis, DNA packaging, lysogeny, and host lysis. Bacillus phage 11143 could be classified as a member of the Siphoviridae family by morphology and genome structure. Genomic comparisons at the DNA and protein levels revealed homologous genetic modules with patterns and morphogenesis proteins similar to those of other Bacillus phages. Thus, Bacillus phages might have a mosaic genetic relationship.

We have prepared poly(ethylene terephthalate) (PET) nanocomposites filled with two different types of fumed silicas, hydrophilic (FS) and hydrophobic (MFS) silicas of 7-nm diameter, by in situ polymerization. We then investigated the morphological changes, rheological properties, crystallization behavior, and mechanical properties of the PET nanocomposites. Transmission electron microscopy (TEM) images indicate that the dispersibility of the fumed silica was improved effectively by in situ polymerization; in particular, MFS had better dispersibility than FS on the non-polar PET polymer. The crystallization behavior of the nanocomposites revealed a peculiar tendency: all the fillers acted as retarding agents for the crystallization of the PET nanocomposites. The incorporation of fumed silicas increased the intrinsic viscosities (IV) of the PET matrix, and the strong particleparticle interactions of the filler led to an increased melt viscosity. Additionally, the mechanical properties, toughness, and modules of the nano-composites all increased, even at low filler content.

In this paper, we propose a method to reduce mobile social network services (SNSs) traffic using a mobile integrated SNS gateway (MISG) to improve network communication performance between the mobile client and SNS servers. The gateway connects the client and SNS servers using the contents adapter and the web service adapter and helps to improve communication performance using its cache engine. An integrated SNS application, the user's client, communicates with the gateway server using integrated SNS protocol. In addition, the gateway can alert the client to new SNS contents because of the broker server implemented by the message queuing telemetry transport protocol. We design and develop the modules of the gateway server and the integrated SNS application. We then measure the performance of MISG in terms of content response time and describe the result of the experiment.
