어플리케이션의 시연은 일련의 상호작용을 포함하기 때문에 많은 시간이 소요된다. 어플리케이션을 시연해야 한다면 통상적으로 발표 세션과 별도로 시연 세션을 진행한다. 하지만, 모바일 단말기를 조작하여 무선으로 어플리케이션을 시연한다면 발표자가 직접 시연을 주도적으로 진행함으로써 전달하고자 하는 메시지를 효과적으로 전달할 수 있을 것이다. 이러한 시연 방법은 기존 모바일 단말기의 성능과 화면 크기의 제약 때문에 구현이 불가능하였다. 우수한 성능과 다양한 기능을 갖춘 스마트폰의 등장으로 스트림 동영상을 실시간으로 그리고 상대적으로 큰 모바일 단말기 화면에서 재생할 수 있고, 또한 시연자가 모바일 단말기 화면의 어플리케이션 영상을 보면서 어플리케이션을 직접 제어할 수 있기 때문에 새로운 시연 방법의 구현이 가능해졌다. 본 논문은 스마트폰을 활용한 모바일 기반 시연 시스템인 '스마트 데모(Smart Demo)'의 설계와 구현에 대해 기술하고자 한다.

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.

본 연구는 화재 발생 시 스마트폰 네비게이션 어플리케이션을 이용한 화재 대피 유도 서비스 시스템이 화재대피 시간에 어떤 영향을 미치는지 살펴보고자 하는 연구이다. 컴퓨터 시나리오 시뮬레이션에서 네비게이션 어플리케이션을 사용하였을 때 대피시간이 22초 단축되었고 실증시뮬레이션 또한 네비게이션 어플리케이션을 사용하였을 때 대피시간이 40초 감소되어 화재 발생 시 피난 시간 단축에 효과적이라는 점을 알 수 있다. 실증 시나리오 시뮬레이션을 한 결과는 피난유도를 실시한 경우가 실시하지 않은 경우보다 피난 종료까지 시간이 39초 더 빠르게 나타났다. 실증 시나리오 시뮬레이션은 피난 경로에 병목현상이 발생하지 않았고 이로인해 컴퓨터 시나리오 시뮬레이션과 실증 시나리오 시뮬레이션의 대피 완료 소요시간의 차이가 발생하였다. 추후 시나리오 시뮬레이션에 학생실습 연구에 기여할 것이다.

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.

본 연구에서는 육상 및 수상 집회, 시위와 비교 상대적으로 보호 및 규율 받지 못하고 있는 해상 집회 및 시위에 대해 공공의 안녕질서를 저해하지 않도록 적절히 규제하면서 동시에 기본권으로서 보호하기 위한 방안을 제시하였다. 먼저, 육상집회 및 시위와 동일하게 보호하고 규율하기 위해 "집시법" 개정을 통하여 해양경비안전관서에서 해상집회 및 시위를 접수받고 이를 관리하는 방안을 제시하였다. 두 번째는 해상의 특수한 환경으로 인해 "집시법" 적용이 곤란할 경우 특별법에 관련 규정을 두고 있는 일본, 미국, 영국과 같이 "해양경비법" 에 해상집회 및 시위와 관련된 내용을 규율하여 국민의 기본권과 공공의 안녕질서 유지 이익이 상호충돌하지 않는 범위에서 해상 집회 및 시위를 관리하는 입법정책적 대안을 제시하였다.

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.
