Recently, more and more firms are considering the adoption of RFID technology because it is expected to make process automation easier and has many different application areas. A review of existing studies about RFID adoption methodology shows that the most of the proposed methodologies are mainly based on economic evaluations. However, in the near future when the adoption and diffusion of RFID become major forces among business firms, it would surely have some limits to decide its adoption solely on the basis of economic considerations. In order for all the important strategic objectives to be considered during the major decision processes, it is necessary to make explicit what the decision makers really want to achieve from the RFID system. In this paper, we propose a general value model of RFID system which can provide an overall vision of all values RFID adoption may offer and a way to search and evaluate alternatives on the basis of these values. Especially, this model contains not only opportunities but also risks of RFID adoption so that a balanced consideration can be made. The model building process was essentially based on the 'value-focused thinking' approach proposed by R. Keeney. The proposed model is expected to provide insights about what to do in the process of introduction in order to maximize the potential benefits and minimize the negative risks. Referring to this value model, the important decisions would have greater chance to be based on a balanced consideration of opportunities and risks.

In the rapidly changing era of the Fourth Industrial Revolution, the business environment surrounding venture companies is also changing rapidly. In recent years, the government has reorganized the venture verification system, including expanding the types and scope of venture companies. This study analyzes the current status of venture preferential system from the perspective of technology-based start-up companies and in addition, this paper proposes a plan for improving the legal system. For analysis, The relevant provisions were confirmed through a search using "venture" as a keyword in the National Legal Information Center and the Korean Court of General Law. Then, meaningful texts were extracted along with relevant data to secure basic data and analyzed by benefits, by means and by content. As a result of the study, Venture preferential treatment system is focused on 'reduction of burden' by the means of benefits, and on 'financial' and 'production' by benefits. In conclusion, four suggestions for improvement are presented. First, efforts are needed to increase the practical applicability of venture-related clauses. Second, the venture preferential treatment system is mainly focused on mitigating the burden, so efforts are needed to find a balance. Third, the venture preferential treatment system is mainly focused on the 'non-research' field, so the benefits of the 'research' field should be expanded. Finally, efforts to discover and overcome blind spots in the venture preferential system should be supported.

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.

Confucianism, the dominating thought in the Choson Dynasty, considered the congruence of scholar and bureaucrat as principle of royal politics, so it was the important affairs to educate and select scholars who excelled in Confucian science and its historical view. The process to educate and select the scholars in accordance with the spirit of Confucianism was called the civil service examination. In this study, we examined the dress and its ornaments of the Confucian students nd that of the successful candidate related to the system of the civil service examination, and focused on the literatures and figures. The Choson Dynasty looked upon the education as important and Confucian scholars and the successful candidate had the superior position in that society. The seems to have been the demarcation between the dress and its ornaments worn by the candidate and the successful candidate. According to the inquiry of the literatures and figures, the candidate is thought to have worn yuguhn(儒巾) or bokkuhn(幅巾) with chongsam(靑衫), nansam( 衫), jikryung(直領) and the successful candidate is thought to have worn bokduh( 頭) with easahwa(御史花), aengsam(鶯衫), danryung(團領) in the Choson Dynasty.

The paper studies the fluid flow profile contained between the orthotropic plate and rigid wall under the action of the moving load on the plate and main attention is focused on the fluid velocity profile in the load moving direction. It is assumed that the plate material is orthotropic one and the fluid is viscous and barotropic compressible. The plane-strain state in the plate and the plane flow of the fluid is considered. The motion of the plate is described by utilizing the exact equations of elastodynamics for anisotropic bodies, however, the flow of the fluid by utilizing the linearized Navier-Stokes equations. For the solution of the corresponding boundary value problem, the moving coordinate system associated with the moving load is introduced, after which the exponential Fourier transformation is employed with respect to the coordinate which indicates the distance of the material points from the moving load. The exact analytical expressions for the Fourier transforms of the sought values are obtained, the originals of which are determined numerically. Presented numerical results and their analyses are focused on the question of how the moving load acting on the face plane of the plate which is not in the contact with the fluid can cause the fluid flow and what type profile has this flow along the thickness direction of the strip filled by the fluid and, finally, how this profile changes ahead and behind with the distance of the moving load.
