Knowledge acquisition is the process that extracts the required knowledge from available sources, such as experts, textbooks and databases, for incorporation into a knowledge-based system. Knowledge acquisition is described as the first step in building expert systems and a major bottleneck in the efficient development and application of effective knowledge based expert systems. One cause of the problem is that the process of human reasoning we need to understand for knowledge-based system development is not available for direct observation. Moreover, the expertise of interest is typically not reportable due to the compilation of knowledge which results from extensive practice in a domain of problem solving activity. This is also a problem of modeling knowledge, which has been described as not a problem of accessing and translating what is known, but the familiar scientific and engineering problem of formalizing models for the first time. And this formalization process is especially difficult for knowledge engineers who are often faced with the difficult task of creating a knowledge model of a domain unfamiliar to them. In this paper, we propose an automated knowledge acquisition tool which is based on an implementation of the Inferential Modeling Technique. The Inferential Modeling Technique is derived from the Inferential Model which is a domain-independent categorization of knowledge types and inferences ［Chan 1992］. The model can serve as a template of the types of knowledge in a knowledge model of any domain.

Advanced driver assistance system(ADAS) is a major technique in the intelligent vehicle field. The techniques for ADAS can be separated in two classes, i.e., methods that directly control the movement of vehicle and that indirectly provide convenience to driver. In this paper, we propose a novel system that gives a visual assistance to driver by translating a night road image to a day road image. We use the black box images capturing the front road view of vehicle as inputs. The black box images are cropped into three parts and simultaneously translated into day images by the proposed image translation module. Then, the translated images are recollected to original size. The experimental result shows that the proposed method generates realistic images and outperforms the conventional algorithms.

Instant Messenger is one of the most popular communication service when translating message or data each other through Internet. For digital crime investigation, therefore, it is obviously important to obtain communication trace and contents derived from Instant Messenger. This is because that gathering traditional communication histories also have been important until now. However, extracting communication trace and contents are not easy because they are generally encrypted or obfuscated in local system, futhermore, sometimes they are located at server computer for Instant Messenger. This paper researches on extracting communication histories against NateOn, BuddyBuddy, Yahoo! messenger and Mi3 messenger, and obtaining user password or bypassing authentication system to Instant Messenger Service when a user use auto-login option.

This study attempts to investigate why Stanislavsky's System, which has been the basis of modern acting, and the American Acting Method, which is the American succession of the System, were forced to become acting theories with a completely different nature. First, this study tracks the publishing and translating process of Stanislavsky's books related to System targeting the major countries of System succession, Russia, the United States, and South Korea, so it confirms that the System has been understood completely differently in each country. Based on this, this study aims to clarify the difference and cause of it in the two acting theories by discussing how the "Experiencing" and the actor's "Double Consciousness", which keep the ground of System, were accepted in the Method. To recognize Stanislavsky's publication, translation, and understanding of the System, which is an inflection point from the System to the Method, will be an attempt to fully understand both acting theories. It is hoped that this study that fundamentally seeks to comprehend System and Method will serve as the foundation for discussion from various perspectives on both acting theories in the future.

RConsumer Portal is defined as "a combination of hardware and software that enables two-way communication between energy service providers(ESP, like KEPCO) and equipment within the consumer's premises". The portal provides both a physical link(between wires, radio waves, and other media) and a logical link(translating among language-like codes and etiquette-like protocols) between in-building and wide-area access networks. Thus, the consumer portal is an important, open public shared infrastructure in the future vision of energy services. This paper presents an XML based standard specification of service-oriented, open protocol for consumer portal system architecture. In the framework level, the XML protocol provides a useful bridge between services and platforms. The proposed standard protocol has been implemented into our developing consumer portal pilot system. The results imply the potential of global standards for consumer portal system by its minimum overhead in network and processor. The reposed XML is designated psXML in this paper.

We propose a Web-based collaborative CAD system which is independent from any platforms, and develop a 3D solid modeler in the system. We developed a new prototype of 3D solid modeler based on the web using Java 3D API, which could be executed without any 3D graphics software and worked collaboratively interacting with each user. The modeler can create primitive objects and get various 3D objects by using loader. The interactive control is available to manipulate-objects such as picking, translating, rotating, zooming. Users connect to this solid modeler and they can create 3D objects and modify them as they want. When this solid modeler is imported to collaborative design system, it will be proved its real worth in today's CAD system. Moreover, if we improve this solid modeler adding to the 3D graphic features such as rendering and animation, it will be able to support more detail design and effect view.

With emerging the Internet of Things (IoT) paradigm, the sensor network and sensor platform technologies have been changed according to exploding amount of sensors. Sensor Registry System (SRS) as a sensor platform is a system that registers and manages sensor metadata for consistent semantic interpretation in heterogeneous sensor networks. However, the SRS is unsuitable for the IoT environment. Therefore, this paper proposes sensor registry data model to register and manager sensor information in the IoT environment. We analyze Semantic Sensor Network Ontology (SSNO) for improving the existed SRS, and design metamodel based on the analysis result. We also build tables in a relational database using the designed metamodel, then implement SRS as a web application. This paper applies the SSNO and sensor ontology examples with translating into the proposed model in order to verify the suitability of the proposed sensor registry data model. As the evaluation result, the proposed model shows abundant expression of semantics by comparison with existed models.

This study evaluates and suggests a new reform plan that overcomes the limitations of the Government Employees Pension Scheme (GEPS) reforms in 2015. Research results indicate that the reforms were insufficient in terms of financial sustainability, functional transparency, and equity. Debates on the GEPS reforms will continue until an equitable solution is found. The priority of the next reform plans should lie in the unification of public pension schemes. In contrast to previous reform proposals, this study suggests a reforms plan, which should result in not the parametric change but the structural change in GEPS. The distinctive point of the new reform plan lies in translating a single-tire into a multi-tire pension system. Accordingly, the new GEPS should consist of a 'National Pension Scheme (NPS)', occupational pension (additional pension), and retirement allowance. Newly appointed government employee officials should be enrolled in the NPS. This study stresses that inequality between the public pension systems will be alleviated and a pension system of social solidarity will be established when the NPS develops in to a basic old age income security system for all citizens including civil servants.

In electro-galvanizing line to manufacture the electro-galvanized steel sheet, polishing system is required to maintain clean surface of conductor roll and to secure the quality of the steel sheet. At the same time, prediction and decision of the replacement cycle for felt material and its brush installed in the polishing system is also important because the brush is directly contacted on the conductor roll surface. In this study, the polishing system has been designed which the brush is repetitive translating according to the longitudinal direction of the conductor roll. Furthermore, the prediction on the wear-life of the felt material used for the brush is performed using the contact pressure extracted by finite element analysis. And to verify the predicted wear-life of the felt material, the experimental study is also carried out. From the comparison result between the predicted and the measured wear-life of the felt material, it is presented that the wear-life and the replacement cycle of the felt material are well predicted by considering a wear compensation factor, and the wear compensation factor is useful and reasonable.
