On this study, we are focusing on the spatial value of the flagship store as an effective way of experiential communication for a brand. The purpose of this study is to create effective methods for the spatial identity by connecting significance of experiential communication and strategic factors of experiential marketing. The process of this research is summarized as follows: First, we select some cases of the flagship stores realizing differentiated methods of experiential marketing and classify the types according to the marketing strategy. Second, we can analyze each function in the context of social, cultural life style. Finally, for the company flagship stores can be a tool to construct a sustainable brand image and tool differentiation, and at the same time for the consumer they can create relationships through customers' experience in the space expressing brand identity and style. Also, flagship stores can be valued as a place offering emotional experiences of cultural consumption as well as product consumption when planned given the style suitable for brand image and strategies.

스마트 그리드(Smart Grid)는 기존의 전력망에 정보 통신 기술을 접목하여 양방향으로 정보를 교환함으로써 에너지 효율을 최적화하는 차세대 지능형 전력망이다. 스마트 그리드 구현을 위한 HPGP 통신 규격은 신흥 스마트 에너지, 홈 자동화, 전기 자동차 통신 어플리케이션 구동을 위해 개발되었다. HPGP 통신 규격은 이전 규격인 HPAV과 상호 운용이 가능하며 저비용, 저전력의 장점이 있다. 새로운 통신 규격의 도입을 위해서는 신뢰성 및 상호 운용성 검증을 위한 분석이 필요하다. 본 논문에서는 이러한 스마트 그리드의 중요한 응용프로그램 중 하나인 전기차와 충전기간 전력선 통신에 대한 신뢰성 테스트 방안으로써 스니퍼 테스트 방법을 제안한다. 또한, 전기차와 충전기 간 HPGP 기반 전력선 통신 환경에서 QCA7000 Device, AVitar, Tool Kit을 이용한 스니퍼 테스트 결과를 분석하였다.

In this paper, an integration tool for the factory automation communication is proposed. It can apply to three kinds of Fieldbus, Manufacturing Message Specification and Personal Digital Assistance based systems in the factory environment. This paper focuses on the development of the testing tool and object-oriented design concepts for the synthesis of communication modules from the factory level to the field level. The integration of each communication module in the distributed environment gains importance for the realization of heterogeneous information processing systems.

In this paper, we have developed a performance analysis tool for communication networks called COMNAS. COMNAS analyses the performance of wide area networks such as Korea Educational Network and Korea Research Environment Open Network which include local area networks such as Ethernet and Token Ring. COMNAS consists of model constructor, simulation implementor, output analyzer and user interface. Attributes of communication networks for modeling either have default values or are entered by user as object units, and implementation of simulation is automatically proceeded by user interface. Ouput results obtained by COMNAS are the status of node, link and entire network such as mean message transmission delay, throughput, utilization, and so on, and they can be selectively obtained upon the request of the user.

In this study, we learned about the emergence of on-line communications originating from peoseuteol Computer Communications, the limitations of online communication, and the definition, traits and development of emoticons that serve as complementary roles, such as emotion and status. After analyzing various literacture and references, it was found that the emoticons functioned as a function of communicating the visual language of the digital era and communicating more sensitively to emotional factors. In a multimedia environment, emoticons are developed at a more advanced stage as the users' own icons due to a stronger tendency to pursue particularity and uniqueness. It is expected that eomotions added with multimedia functions will be more popular and vary in type. However, although the diversification of emotions as a commercial tool is already actively progressing, there appears a reverse effect in which an excessive use of emoticons is considered insincere in online communications. In such a background, research should be conducted that can support a systematic and effective development of emoticons through visual research rather than producing multimedia emoticons indiscreetly.

기존의 소프트웨어 개발은 SW품질을 중요시 하지만, 고품질에 대한 문제가 아직도 존재한다. 또한 기존 레가시 시스템는 개발자나 설계의 부재 경우가 많고, 코드의 내부 복잡도와 모듈간의 결합도가 높을 가능성이 높다. 따라서 코드 가시화를 통한 복잡도 개선은 고품질화과 더불어 코드 모듈의 재사용과 유지보수등과 직접적 관련성이 있다. 본 논문은 기존 SW가시화용 자동 Tool Chain 기반에서 여러 리펙토링 방법 절차 적용으로 복잡도 개선을 제안 한다. 이런 코드 가시화가 결과적으로 타깃의 결합도를 줄일 수 있다. 기존의 레가시 코드에 자동 Tool chain적용은 고품질 적용이 충분히 예상된다.

3D-ray tracing tool은 신호의 반사, 투과, 그리고 회절까지 고려하여 3차원 공간에서 더욱 정확한 네트워크 성능을 분석하기 위한 소프트웨어이다. 통신표준에서는 통신 자원을 효율적으로 제공하기 위해 소형셀을 포함한 Heterogeneous Networks (HetNets)을 도입하고 있다. 매크로셀에 비해 좁아진 커버리지를 사용하는 소형셀 환경에서는 3D 공간에서 성능분석이 중요해 졌다. 또한 지형구조와 건물의 배치 그리고 3D 빔포밍(beamforming) 기술 등의 사용으로 인해 네트워크 환경이 복잡해지기 때문에 기존의 2차원 수학적 모델들을 이용하여 성능을 분석하기에는 어려움이 따른다. 본 논문에서는 소형셀 네트워크 성능을 더욱 효율적으로 분석하기 위한 3D-ray tracing tool을 활용한 성능평가 방법을 소개한다. 성능평가 결과 기존의 방법보다 3D-ray tracing tool을 활용한 성능평가 방법이 소형셀 환경에서 더욱 적합하다는 결론을 내렸다.

File system forensics typically focus on the contents or timestamps of a file, and it is common to work around file/directory centers. But to recover a deleted file on the disk or use a carving technique to find and connect partial missing content, the evidence must be analyzed using cluster-centered analysis. Forensics tools such as EnCase, TSK, and X-ways, provide a basic ability to get information about disk clusters, but these are not the core functions of the tools. Alternatively, Sysinternals' DiskView tool provides a more intuitive visualization function, which makes it easier to obtain information around disk clusters. In addition, most current tools are for Windows. There are very few forensic analysis tools for MacOS, and furthermore, cluster analysis tools are very rare. In this paper, we developed a tool named FACT (Forensic Analyzer based Cluster Information Tool) for analyzing the state of clusters in a HFS+ file system, for digital forensics. The FACT consists of three features, a Cluster based analysis, B-tree based analysis, and Directory based analysis. The Cluster based analysis is the main feature, and was basically developed for cluster analysis. The FACT tool's cluster visualization feature plays a central role. The FACT tool was programmed in two programming languages, C/C++ and Python. The core part for analyzing the HFS+ filesystem was programmed in C/C++ and the visualization part is implemented using the Python Tkinter library. The features in this study will evolve into key forensics tools for use in MacOS, and by providing additional GUI capabilities can be very important for cluster-centric forensics analysis.

Safety-critical systems related to the railway communications are currently undergoing changes. Mechanical and electro-mechanical devices are being replaced by programmable electronics that are often controlled remotely via communication networks. Therefore designers and operators now not only have to contend with component failures and user errors, but also with the possibility that malicious entities are seeking to disrupt the services provided by theirs systems. Recognizing the safety-critical nature of the types of communications required in rail control operations, the communications infrastructure will be required to meet a number of safety requirements such as system faults, user errors and the robustness in the presence of malicious attackers who are willing to take determined action to interfere in the correct operation of a system. This paper discusses the safety strategies employed in the railway communications and proposes a security mechanism for Korean railway communication system. We present the developed communication safety evaluation tool based on the proposed security mechanism and also evaluate its protecting capability against the threats of masquerading, eavesdropping, and unauthorized message manipulation.
