  • The transmission valuation methodology we propose here captures the interaction between generation and transmission investment decisions recognizing that a transmission expansion can impact the profitability of new resources investment, so that a methodology should consider both the objectives of investors in resources and the transmission planner. In this perspective, this paper purports to develop the mixed-integer programming based transmission expansion planning optimization software, which is well designed to determine the construction time and place of new generators, transmission lines, and substations as well as their capacities to minimize total expenditures related to their investment and operations while meeting technical constraints such as capacity margin, constitution ratio of power resources, spinning reserves, energy and fuel constraints, transmission line outages and losses, pi-type branching, and so on. Finally, Garver's simple system is adopted to validate not simply the accuracy but the efficiency of the proposed model in this paper.

  • This research was launched as an attempt to help create a new value-added product called "Green Jujube Chip." To accomplish the objectives, consumers value by attributes of Green Jujube Chip should be estimated. We used Choice Experiment for analysis, which we used to arrive at pricing of specialty jujube chips based on the conditional logit model. As a result, MWTP were estimated at 1333 Won/unit for Mid-size Company Product, 1752 Won/unit for Large Company Product, 1703 Won/unit for University Affiliation, 350 Won/unit for packing unit, 548 Won/unit for rating the raw fruit, 1,322 Won/unit for HACCP, and 1,166 Won/unit for ISO22000. The consumer's WTP for Green Juju Chip, associated with the university-brand recognition, was higher than a product produced by a mid-sized company but lower than a product by a large company. Given how the consumers regard the university-brand product as a specialty item, it is necessary to create value-added products that meet such high expectation. Therefore, we recommend the producers to acquire HACCP Food Safety Certification and the value-added product has used the highest quality raw fruit.

  • Nowadays, the whole world is putting in the knowledge information society by the internet which is connecting the global network. The internet enable us to see the life of the other people in real time. Most of health care professional obtain and update their new knowledge and skills through continuing education. EMTs who works five or ten shifts per day are not easy to attend continuing education session usually offered during their off-times. One of solutions to this problem would be to develop a education program which does not limit time and place. There has been increasing interest in the use of computers in medical education, but all designated facilities and teachers have no sufficient preparations for the education and training of EMT. There has been less attention to the rationale for the use and selection of applications. This article discusses an approach to the selection of medical informatics applications for the undergraduate medical curriculum. The aim of this study is to develop and evaluate a web-based continuing education program, to help EMT improve their knowledge of transfusion therapy and medical law, and to enhance their ability to contribute to the quality of patient care. The program generally was well received by EMTs. The program is a useful adjunct to the existing continuing education program. It also could be used in EMT student education and other health sciences.

  • The evolution of spectrum sharing technology enables the creation of many business scenarios and business models such as TV white space service. Business models considering spectrum sharing should guarantee economic feasibility for service providers and increasing benefit for service users. In addition, new business models should contribute to economic activation in the wireless telecommunication service industry. It is therefore necessary to design quantitative evaluation methods for selection of the best business models. The methods should reflect the various points of view of valuation. Our research addresses evaluation method for business models considering spectrum sharing. We define evaluation indicators to reflect the distinct characteristics of spectrum sharing. Also, we adopt analytic hierarchy process(AHP) to derive the weights of each indicator to evaluate business models considering spectrum sharing.

  • Heritage resources have become important social assets as the global interests in heritage tourism increased. Utilization of heritage as unique tourist destination has positive effects on regional economy, which in turn plays an important role in heritage conservation. However, it was found that the essential quality of heritage resources has been degraded and even destroyed when excessive use was permitted. This undesirable side-effects of heritage tourism have led to the growing concern for sustainable tourism that can contribute to both utilization and conservation of heritage. In order for sustainable tourism to be effectively implemented, it is crucial for visitors to be aware of the need for heritage conservation because they are the most important consumers of the heritage. The purpose of this study was to suggest some basic information for sustainable tourism by investigating visitors' evaluation of conservation and use values of heritage resources. The study sites were the two Korean traditional temples(Sokrisan Bubjusa and Naejangsan Naejangsa) and contingent valuation method was used. 390 visitors in Bubjusa and 308 visitors in Naejangsa participated in the questionnaire survey. From the results, sustainable tourism is possible in such heritage areas as traditional temples because the participants had relatively balanced values for heritage conservation and use. The WTP for natural conservation value was found to be highest in both temples; visitors may be more agreeable with the heritage conservation plan if the sustainability of natural resource is emphasized. Also, the use value of heritage could be influenced by the tourism utilization of the area where the heritage was located. If there are no other famous tourist destinations except the heritage in the area, additional plans to develop alternative destinations should be prepared in order to formulate the agreement on the need to protect the heritage among visitors, local communities, and government.

  • Recently, the deepening of the environment and accompanying concerns produce various environmental regulations. For example, EPR(Extended Producer Responsibility) is emphasized in many countries such as USA and Europe. According to this, the construction of a reverse supply chain is under compulsion. A diversity of parts can be controlled by a government or enterprises in the construction and management of a reverse supply chain and the effect to the environment is changed according to the policy. Therefore, it is essential to understand the effects of regulations or policies of a government and enterprises on a supply chain. The object of this research is to develop a means to assess the management efficiency and the environmental effect over a whole supply chain and show the effects of various reverse supply chain construction policies on a supply chain. This model can be utilized to establish appropriate policies by understanding the change in the management efficiency and the environmental effect according to the reverse supply chain construction and management method.

  • Intellectual property rights play a key role in employment creation and income generation plays an important role, especially in the creative economy. Many companies are ultimately increasing efforts to boost the company's financial performance, such as maximizing profits by building a strong brand assets amid committed to brand management in this paradigm. Reasonable evaluation and commercialization of technology transactions, financial assistance, investment decisions, trademark brand value for the reactivation (revitalizing) for the purposes of M & A, litigation, brand strategy will be said to be very important. In spite of the importance, the awareness of the property and the capabilities to assess are hardly sufficient. Thus, this study, targeting companies with valid trademarks for value assessment, conducted case analysis by cost method and income approach; the analysis presented the result from 2.05 million by the cost method to 2.7 million by the income approach applied to a variable discount rate and adjustment contribution. However, now that the implication was drawn from a single company, further studies covering case study and application plan according to scale and type of diverse company groups should be continued.

  • In this paper, we propose the algorithm that automatically measures the height of the object to move on the base plane by using the geometric information. To extract a moving object from real-time images creates the background image and each pixel is modeled by the three values. The extracted region is represented by cardboard model and calculates the coordinate center in the each part. The top and bottom point of an object are extracted by the calculated coordinate center and an iterative computation. The two points, top and bottom, are used for measuring the height. Given the vanishing line of the ground plane, the vertical vanishing point, and at least one reference height in the scene; then the height of any point from the ground may be computed by specifying the image of the point and the image of the vertical intersection with the ground plane at that point. Through a confidence valuation of the height to be measured, we confirmed similar actual height and result in the simulation experiment.
