An application's demonstration takes much time because there are a number of interactions involved. When a demonstration is indeed necessary, a separate session of demonstration is commonly carried out besides a presentation. If one can control the application wirelessly using mobile devices, he can present his messages effectively by having a live self-paced demonstration. This method of demonstration has not been possible to implement due to the limitations on performance and/or screen size of feature phones. Lately commercialized smartphones, however, are equipped with better performance and various features so that they can be utilized to implement the new demonstration method. With these smartphones, one can view the application images right on mobile devices to control applications directly. This paper describes the issues of design and implementation of a mobile-based demonstration system, 'Smart Demo'.

In plant-pathogen interactions, Magnaporthe oryzae causes blast disease on more than 50 species of 14 monocot plants, including important crops such as rice, millet, and most 15 recently wheat. M. oryzae is a model fungus for studying plant-microbe interaction, and the main source for fungal pathogenesis in the field. Here we report that MoJMJD6 is required for conidium germination and appressorium formation in M. oryzae. We obtained MoJMJD6 mutants (ΔMojmjd6) using a target gene replacement strategy. The MoJMD6 deletion mutants were delayed for conidium germination, glycogen, and lipid droplets utilization and consequently had decreased virulence. In the ΔMojmjd6 null mutants, global histone methyltransferase modifications (H3K4me3, H3K9me3, H3K27me3, and H3K36me2/3) of the genome were unaffected. Taken together, our results indicated that MoJMJD6 function as a nuclear protein which plays an important role in conidium germination and appressorium formation in the M. oryzae. Our work provides insights into MoJMJD6-mediated regulation in the early stage of pathogenesis in plant fungi.

In the fields of reliability application, the most commonly used test methods for reliability demonstration are zero-failure acceptance tests since they require fewer test samples and less test time compared to other test methods that guarantee the same reliability with a given confidence level. For products with lognormal lifetime distribution, the value of scale parameter is usually assumed to be known in designing reliability demonstration tests. It is important to select correct values of scale parameters to guarantee the specified reliability with given confidence level exactly. The effect of using wrong values of scale parameters in designing reliability demonstration test for products with lognormal lifetime distribution is examined and selecting proper values of scale parameters for conservative reliability demonstration is discussed.

This study examined how the fire evacuation induction service system using a smartphone navigation application in the event of a fire affects the fire evacuation time, and the following conclusions were drawn. 1. The evacuation time was reduced by 22 seconds when the navigation application was used in computer scenario simulation. Even in the demonstration simulation, the evacuation time was reduced by 40 seconds when the navigation application was used. This indicates that the navigation application is effective in shortening the evacuation time in case of fire. 2. As a result of the demonstration scenario simulation, the time until the end of evacuation was 39 seconds faster in the case of evacuation guidance than in the case where it was not conducted. 3. No bottlenecks occurred in the evacuation route during the demonstration scenario simulation. As a result, there was a difference in the time required to complete the evacuation between the computer scenario simulation and the demonstration scenario simulation.

The purpose of this study is to review the appropriateness of deploying private security guards using SMS emotional language analysis at the current assembly and demonstration sites, which rely only on the police force, and to suggest a plan. Therefore, it is intended to contribute to suppressing the problems at the assembly and demonstration sites and present a new paradigm for responding to the assembly and demonstration sites based on the study's results. First, it is necessary to prepare a legal basis for the deployment of private security guards in the 'Security Services Industry Act' and 'Assembly and a Demonstration Act'. Second, there is a need for a 'security company selection criteria' for selecting security companies with a lot of experience, such as collective civil petition sites and security for national critical facilities (special security services). Third, it is necessary to prepare financial resources for the deployment of private security guards. This study is expected to serve as a new cornerstone for effective management of assembly and demonstration sites through mutual complementation of the police and private security.

Until now some countries including South Korea have made big progress and many efforts in the development of high temperature superconductor (HTS) power equipments. Especially, HTS Cable and superconducting fault current limiter (SFCL) are the strongest candidates among them from the viewpoint of applying to real grid. In South Korea, HTS cable and SFCL have been installed in test fields and tested successfully at Gochang PT Center of KEPCO. In order to meet practical requirements and be feasible in real grid, a demonstration project for HTS cable and SFCL systems, called GENI(green superconducting electric power network at Icheon substation) project, has been initiated to install 23kV HTS cable and SFCL systems in a utility network in South Korea since 2008. Namely, it says the first demonstration project for the application HTS system to real smart grid in South Korea. This paper presents the design and the application plan of the 22.9kV HTS cable and SFCL in 154kV Icheon substation in South Korea with the viewpoint of applying in Smat Grid.

Recently, request far application of advanced commercial technology to the defense acquisition process, to reduce the budget and shorten development time, has been increased. To accomplish these goals, the Advanced Concept Technology Demonstration(ACTD) is used for the defense acquisition process in Korea. And User Utility Assessment is tested to make a decision for transition to acquisition process. But this process does not include measurement of technology maturity and impacts of interface and interaction among the technologies. In this research, we propose the needs of measurement of TRL and IRL and application of SRL to reduce the risk during development phase, to understand the relations of technologies, and to fulfill the requirement far transition of the ACTD project to system development and demonstration process.

We study on the significance and application of the whole body form diagnosis. The results were as follows; The general form diagnosis is the method to observe the individual physiology and pathology. The phase of thinking, the current and activity of KI, the pattern of general form diagnosis have organic relations with the symptoms. The general form diagnosis is made up the principle of the imaging phase, therefore it must make synthetic union the differentiation of syndromes. The general form diagnosis of NAE GYEONG shows the typical phases and it is divided with the sight of YIN YANG and Five-Element. The general form diagnosis of SEOP GAE is practiced the theory of constitution's demonstration before the understanding of symptoms. Then JANG NAM tried the type of constitution's demonstration. The general form diagnosis of DONG MU becomes the diagnostic root of constitution's demonstration in four type constitution theory.

In this study, I present solutions to properly regulate assembly and demonstration at sea which has not been relatively secured and regulated compared to that of on land and inland waters so it may not violate public safety and order, and at the same time to secure it as a basic human right. Firstly, to protect and regulate in the same way with assembly and demonstration on land, I suggest to make amendments to "Law on Assembly and Demonstration" so that Korea Coast Guard Station can accept applications and administrator maritime assembly and demonstration. Secondly, in special cases where there are difficulties in the application of "Law on Assembly and Demonstration" due to the special maritime environment, following the example of Japan, America and England who have regulations in related special laws, I suggest an legislative alternative to add regulations on maritime assembly and demonstration in "Law on Maritime Guard" so that we can administer maritime assembly and demonstration in a way which there should be no conflict between basic human right of people and conservation of public safety.

A Bayesian zero-failure reliability demonstration test method for products with exponential lifetime distribution is presented. Beta prior distribution for reliability of a product is used to design the Bayesian test plan and selecting a prior distribution using a prior test information is discussed. A test procedure with zero-failure acceptance criterion is developed that guarantees specified reliability of a product with given confidence level. An example is provided to illustrate the use of the developed Bayesian reliability demonstration test method.
