It has been proved that information and communication technology (ICT) solutions for personalized health (PHealth) and ambient assisted living (AAL) can support people in their daily life activities. Several solutions have been demonstrated to empower different levels of services through seamless data acquisition and specific users' interaction modalities. Usually services usability and accessibility are handled in the design process and are validated with small users' groups. Moreover, while service design and systems development have been extensively described in literature, service deployment methodologies are not properly addressed and documented. Proper reference guidelines are also missing. The most common methodologies like unified process (UP) or ICONX can cover only the design and the development of PHealth services without a clear description on the following phases such as deployment, service provision and maintenance. These phases present several risks to be taken into account right from the beginning of the implementation of PHealth or AAL services. This paper focuses on the description of a structured methodology to deploy PHealth services and how this process can be supported by integrated software routines and adapting the UP framework in particular the "Transition phase."

This treatise makes clear not only a structural methodology of 'the conceptual blending theory' using in a linguistics could be applied to the similar process in a hybrid design but also both methods include the same meaning construction in the sense of a mutual educational system. Both methods have something in common that they are fundamentally focused on a metaphorical expression which implies poetic messages to be concentrated on a formal structure. Therefore, the purpose of this treatise is to examine the structural characteristics in the hybrid design in order to analyze the rhetorical expressions(metaphor, allegory) as symbols of communication. One of the those is intertextuality that expresses metaphorically by blending and borrowing codes and another is hypertextual space where various texts twines around each other making brand-new and diverse organizations, as the combined allegory with a number of hidden expression. Ultimately, it is important that this approach could verify whether it deals the illogical present state of a spacial form or structure with a kind of mechanism of a 'conceptual blending theory' or not.

Purpose This study aims to develop a job model for data convergent talents to meet the rapidly changing demands of the data industry. To create a job model, we first define and categorize data convergent talents with balanced competencies in data technology and domain knowledge, and then develop a job model by investigating job areas, scope, activities, and competencies. Design/methodology/approach The research is conducted using the following procedures and methodology. First, we conduct a current status survey on data talent demand, data talent policies, data talent programs, and curricula at home and abroad; second, we collect opinions on the jobs and competencies required for data convergent talents and curricula for talent development through in-depth interview with experts; and third, we present the job areas and job activities of data convergent talents derived from the previous status survey and expert opinions based on the National Competency Standards(NCS). Findings The research findings indicate that there are total of six job roles for data convergent talents, including data scientist, data planner, data architect, data developer, data engineer, and data analyst. It was observed that each of these roles requires the development of common competencies within their respective fields, followed by a need for further specialization into specific competencies within each professional domain.

Purpose - Due to highly elevated levels of competition, many companies today have to face the problem of decreasing profits even when their actual sales volume is increasing. This is a common phenomenon that is seen occurring among companies that focus heavily on quantitative growth rather than qualitative growth. These two aspects of growth should be well balanced for a company to create a sustainable business model. For supply chain management (SCM) planners, the optimized, quantified flow of resources used to be of major interest for decades. However, this trend is rapidly changing so that managers can put the appropriate balance between sales volume and sales quality, which can be evaluated from the profit margin. Profit optimization is a methodology for companies to use to achieve solutions focused more on profitability than sales volume. In this study, we attempt to provide executional insight for companies considering implementation of the profit optimization system to enhance their business profitability. Research design, data, and methodology - In this study, we present a comprehensive explanation of the subject of profit optimization, including the fundamental concepts, the most common profit optimization logic algorithm -linear programming -the business functional scope of the profit optimization system, major key success factors for implementing the profit optimization system at a business organization, and weekly level detailed business processes to actively manage effective system performance in achieving the goals of the system. Additionally, for the purpose of providing more realistic and practical information, we carefully investigate a profit optimization system implementation case study project fulfilled for company S. The project duration was about eight months, with four full-time system development consultants deployed for the period. To guarantee the project's success, the organization adopted a proven system implementation methodology, supply chain management (SCM) six-sigma. SCM six-sigma was originally developed by a group of talented consultants within Samsung SDS through focused efforts and investment in synthesizing SCM and six-sigma to improve and innovate their SCM operations across the entire Samsung Organization. Results - Profit optimization can enable a company to create sales and production plans focused on more profitable products and customers, resulting in sustainable growth. In this study, we explain the concept of profit optimization and prerequisites for successful implementation of the system. Furthermore, the efficient way of system security administration, one of the hottest topics today, is also addressed. Conclusion - This case study can benefit numerous companies that are eagerly searching for ways to break-through current profitability levels. We cannot guarantee that the decision to deploy the profit optimization system will bring success, but we can guarantee that with the help of our study, companies trying to implement profit optimization systems can minimize various possible risks across various system implementation phases. The actual system implementation case of the profit optimization project at company S introduced here can provide valuable lessons for both business organizations and research communities.

The defense system development process is a process of developing various systems that perform functions in various functional areas such as battlefield awareness, command control, force application, and logistical support. In other words, the defense system development process is a process of developing many systems simultaneously in various functional areas. Various systems developed through this process should be interoperable so that they can be integrated and operated in a joint warfighting environment. To successfully implement this, the US Department of Defense uses the Joint Capability Integrated Development System(JCIDS) for the defense system development, and within this JCIDS processes the Capability Based Assessment(CBA) methodology as its core technology. This CBA methodology transforms the mission activity requirements to functional capability requirements logically and transforms the functional capability requirements to system requirements logically also. Smart City is a city that improves the convenience and quality of life of the citizen by integrates various systems that perform various functions of the city and smarties various functional systems with smart services by using IT technology. In other words, defense system development and smart city development have a common feature of the process of developing many systems simultaneously in various functional areas. In order to address the problem of having to develop many systems simultaneously in each functional area, it is important to logically transform the various mission scenarios into functions and logically transform the functions into systems. Therefore, a joint capability integrated development system and its core methodology, Capability Based Assessment(CBA), can be applied to smart city development. This paper proposes a method for performing a smart city concept design method using the capability based evaluation (CBA) method.

The market size of plant projects in overseas is so large that domestic EPC project contractors are actively seeking the overseas projects and then trying to meet completion plans since successful fulfillment of these projects can provide great opportunities for them to expand into new foreign markets. International EPC projects involve all of the uncertainties common to domestic projects as well as uncertainties specific to foreign projects including marine transportation, customs, regulations, nationality, culture and so on. When overseas project gets off-schedule, the resulting uncertainty may trigger unexpected exceptions and then critical effects to the project performance. It usually require much more time and costs to encounter these exceptions in foreign sites compared to domestic project sites. Therefore, an exception handling approach is required to manage exceptions effectively for successful project progress in foreign project sites. In this research, we proposed a methodology for prediction and evaluation of exceptions caused by risks in international EPC projects based on sensitivity analysis and Bayesian Networks. First, we identified project schedule risks and related exceptions, which may meet during the fulfillment of foreign EPC projects that is performed in a sequence of engineering, procurement, preparatory manufacture, foreign shipping, construction, inspection and modification activities, and affect project performance, using literature review and expert interviews. The impact of exceptions to the schedule delay were also identified. Second, we proposed a methodology to predict the occurrence of exceptions caused by project risks and evaluate them. Using sensitivity analysis, we can identify activities that critically affect schedule delay and need to focus by priority. Then, we use Bayesian Networks to predict and evaluate exceptions. Third, we applied the proposed methodology to an international EPC project example to validate the proposed approach. Finally, we concluded the research with the further research topics. We expect that the proposed approach can be extended to apply in exception management in project management.

An exhibition administrator, one who works in the exhibition space of museums and exhibition halls, has carried on various tasks in order to improve the exhibition standard and viewer's satisfaction. Although exhibition administrators have a variety of direct perceptions regarding an exhibition in the actual on-site space, a study on their consciousness was absent. Thus, this study was to comprehend the awareness of how the consciousness of exhibition administrators, who directly understand the various matters regarding the exhibition on-site, was structured and to investigate the difference between the consciousness of exhibition viewers and designers. For the study, Q-Methodology, which can scientifically manage the consciousness such as awareness and the acquired attitudes through individual experiences from a specific group, was applied. The classification of 33 Q-methodology research questions was carried out with 18 exhibition administrators, who are working at either national or public museums and exhibition halls in Korea, and the Principal Component Analysis (PCA) using the QUANL PC program was performed. The results of the analysis provided the following 4 types: 'viewer attraction and exhibition method oriented', 'exhibition standard oriented', 'public relations oriented' and 'the public and government's interest oriented'. Each type showed significant characteristics. Additionally, n showed that 'exhibition standard oriented' was the common type after comparing the type of consciousness among the 3 groups of people, such as an exhibition administrator, an exhibition designer, and a viewer. It indicated that the types of 'public relations oriented' and 'the public and government's interest oriented' from the consciousness category for the exhibition administrator were the most independent type, not being found in any of the other groups. And the Significant correlation between the exhibition viewers and designers was identified after examining the Pearson's correlation among the 3 groups.
