Global economy is moving to digital economy accelerated by the rapid development of ICT (information and communication technology). However, the progress in e-business in developing countries has been slow due to the lack of experience, technology, and basic infra structure. One way to solve this problem is to provide them with customized e-business solution, training, and contents service. In this paper, we design an E-business Training Supporting System (E-TSS) for developing countries. It consists of a simple business blog to support business web page and a customized e-business solution. The E-TSS is customized for individual country. This customization becomes more effective utilizing an intelligent agent based upon recognizing unique characteristics such as language and time. The E-TSS is implemented and utilized by APEC (Asia-Pacific Economic Cooperation) Women's e-Biz Center.

The study intends to systematically arrange and classify the museum layouts in terms of their structure of exhibition space. The exhibition space, here, means the whole area where visitors are allowed to move and visit in museums. Through this, I tied to understand the characteristics and trends comparing and analyzing international and national exhibition space layout, and then grope the standard in case of establishing museum. The first criteria is based on the point of view that the typical museum experience is made in the exhibition space. Accordingly, the exhibition space can be grouped into two categories; one is 'room type' consisting mostly of individual rooms as in classical museums, and the other is 'open plan type' consisting free standing walls as in miesian free plan. The second criteria is dependent on the way how visitors move about in exhibition spaces. In other words, museum layouts can be categorized in terms of mutual connection between individual spaces including exhibition spaces and corridor spaces designated for the purpose of moving. consequently, the layouts can be categorized into five groups such as 'free plan', 'linear type', 'room to room', 'room & corridor' and 'composition type'. The third criteria is about the overall structure of museum layouts including such elements as whether it contains a certain type of central major space or not and whether and how the exhibition spaces are connected to it. By applying these classificatory criteria, the study analyzed and classified 90 sample of museum layouts in order to understand clearly and succintly the spatial characteristics and implications contained in them.

The ocean and meteorological payloads of COMS are concerned to experience degration of image quality due to the disturbance induced by the motion of moving parts of the payloads. And thruster firings for stationkeeping and wheel offloading are expected to degrade the image quality of the optical payloads. In case of COMS, in order to keep the optical payload free from the mechanical interference from the other payload, the operation design approach has been taken. This paper introduces the operation design of COMS taken to avoid these problems. In order to meet users requirement by avoiding the degradation of image quality, the timeline of optical payloads and housekeeping are optimized, and operational constraints are applied to the mirror motion of the meteorological payload. This paper also introduces the results of time budget analysis performed to validate the operation design.

Recently, the performance and function of electrical and electronic system in automotive vehicles is developing at a rapid rate with the advancement of IT technologies. Combined together with micro-controller and sensor technologies, the Vehicle Smart System (VSS) being developed to improve driver's convenience and comfort has been employed to a variety of applications. In addition to the convenience system, the Auto-parking Assistance System (AAS) that is now attracting a new attention has been already applied to some vehicles, but it is currently limited to luxury car models only. In this paper, we present a fuzzy controller that enables autonomous parking assistance without the AAS. The controller can perform the assistance with information provided from moving status, current position and steering angle as one is able to park a car based on his/her experience and knowledge for driving and parking. We have evaluated its performance of the proposed controller by simulation and tested the excellence of the controller by building a model vehicle embedded with the micro-controllers.

Mixed and augmented reality technique deals with mixing content between real world and virtual world containing augmented reality and augmented virtuality excluding of pure real and pure virtual world. In mixed and augmented reality, if a live actor and entity moving in real world can be embedded more naturally in 3D virtual world, various advanced applications such 3D tele-presence, 3D virtual experience education and etc can be serviced. Therefore, in this paper, we propose a standard model which is supporting to embed the live actor and entity into 3D virtual space, and to interact with each other. And also the natural embedding and interaction of live actor and entity can be performed based on the proposed model.

Nuclear power plants (NPP) are complex socio-technological systems that rely on the success of both hardware and human components. Empirical studies of plant operating experience show that human errors are important contributors to accidents and incidents, and that organizational factors play an important role in creating contexts for human errors. Current probabilistic safety assessments (PSA) do not explicitly model the systematic contribution of organizational factors to safety. As some countries, like the United States, are moving towards increased use of risk information in the regulation and operation of nuclear facilities, PSA quality has been identified as an area for improvement. The modeling of human errors, and underlying organizational weaknesses at the root of these errors, are important sources of uncertainty in existing PSAs and areas of on-going research. This paper presents a review of research into the following questions: Is there evidence that organizational factors are important to NPP safety? How do organizations contribute to safety in NPP operations? And how can these organizational contributions be captured more explicitly in PSA? We present a few past incidents that illustrate the potential safety implications of organizational deficiencies, some mechanisms by which organizational factors contribute to NPP risk, and some of the methods proposed in the literature for performing root-cause analyses and including organizational factors in PSA.

The theoretical foundations of GA are the Schema Theorem and the Building Block Hypothesis. In the Meaning of these foundational concepts, simple genetic algorithm(SGA) allocate more trials to the schemata whose average fitness remains above average. Although SGA does well in many applications as an optimization method, still it does not guarantee the convergence of a global optimum. Therefore as an alternative scheme, there is a growing interest in a co-evolutionary system, where two populations constantly interact and co-evolve in contrast with traditional single population evolutionary algorithms. In this paper, we propose a new design method of an optimal fuzzy logic controller using co-evolutionary concept. In general, it is very difficult to find optimal fuzzy rules by experience when the input and/or output variables are going to increase. So we propose a co-evolutionary method finding optimal fuzzy rules. Our algorithm is that after constructing two population groups m de up of rule vase and its schema, by co-evolving these two populations, we find optimal fuzzy logic controller. By applying the proposed method to a path planning problem of autonomous mobile robots when moving objects exist, we show the validity of the proposed method.

Purpose: The purpose of this study was to examine the impact of ego-resilience, career planning on turnover intention of career-focused nurses working in general hospitals. Methods: The subjects were 673 nurses with clinical experience with more than 1 year working in general hospitals in Seoul and Gyeonggi-do, from February1 to June 30, 2016. The collected data were analyzed with t-test, ANOVA, Pearson's correlation and multiple regression anaby using SAS (9.4ver). Results: The factors affecting the turnover intention of career nurses were identified by age, current hopes of moving to the workimg department, and career planning. These variables accounted for 18% of career nurses' turnover intentions. Conclusions: The results of this study suggest that the higher the degree of career planning of career nurses, the lower the turnover intention. However, ego-resilience did not show the influence of turnover intention. There is a need to develop a career management program that enhances ego-resilience and systematic career planning to reduce turnover intentions.
