Cost of capital is one of the key factors of accounting regulation policy for telecommunication market. This paper aims at investigating efficient policy improvements concerning accounting regulation for telecommunication market focused on cost of capital calculation methods and its application. At First, cost of capital estimating method should be improved. In estimating the cost of equity capital, it is necessary to use benchmark method for Equity risk premium. It will reduce analytical errors caused by a rapid economic change and inflation. It is also more desirable to use debt premium adding method for the cost of debt capital. Optimal capital structure method may be considered a better way to estimates capital structure. Secondly, cost of capital estimating process also has to be reformed. Telecommunication industry changes rapidly so it does not reflect fast environmental changes. Therefore, cost of capital should be calculated every year. Cost of capital should be calculated by individual companies. There is information asymmetry between regulators and regulatees. Because of that cost of capital calculating process takes long time and cost a lot. To solve this problem, regulator should legislate on cost of capital calculation and then regulating companies report the calculating result. Lastly, major telecommunication companies are all listed now and it is possible to calculating it separately. We must continuously improve the estimating method and application of cost of capital and due to the fast growing of telecommunication industry. The process of determining the calculating method must be discussed and best method chosen.

In contemporary society, it is increasingly common to spend more time indoors. As such, there is a continually growing desire to build comfortable and safe indoor environments. Along with this trend, however, there are some serious indoor-environment challenges, such as the quality of indoor air and Sick House Syndrome. To address these concerns the government implements various systems to supervise and manage indoor environments. For example, green building certification is now compulsory for public buildings. There are three categories of green building certification related to indoor air in Korea: Health-Friendly Housing Construction Standards, Green Standard for Energy & Environmental Design(G-SEED), and Indoor Air Certification. The first two types of certification, Health-Friendly Housing Construction Standards and G-SEED, evaluate data in a drawing plan. In comparison, the Indoor Air Certification evaluates measured data. The certification using data from a drawing requires a considerable amount of time compared to other work. A 2D tool needs to be employed to measure the area manually. Thus, this study proposes an automatic assessment process using a Building Information Modeling(BIM) model based on 3D data. This process, using open source Industry Foundation Classes(IFC), exports data for the certification system, and extracts the data to create an Excel sheet for the certification. This is expected to improve the work process and reduce the workload associated with evaluating indoor air conditions.

The domestic game industry has constantly developed in a short time by concentrating on online games, and keeps growing as a highly added value industry. Also, in the social aspect, it has been seeking various alternatives to place online games as positive and new play culture in the digital era by avoiding negative criticism on game addictiveness. One of important factors in expanding the infrastructure of the game industry and developing it as a type of culture is not simply to develop the existing core genres (on the basis of profits), but to promote the approach of mixture with various contents and of positive functions and thereby enlarge users through various game genres. That is, it is to design games with positive themes and easy immersion by targeting a variety of game users. Such expansion of game design approach is a starting point to develop the infrastructure of the game industry. In the aspect, training professional human resources on the basis of academic and educational process is of significance. Therefore, this work was intended to suggest examples of design approach education based on creativity subject among various subjects with positive functions, and then propose an education process to which Capstone design education contents were applied.

Recently, there have been growing interest in teachers' professional development since teachers were regarded as a critical factor in the context of the reform efforts. Along with these efforts, educational researchers have continued to implement various programs to improve teachers' subject matter knowledge, beliefs, and their practices. Although considerable researches have been done regarding the efficiency of these programs, most of them have focused on individual teacher's change. However, a "teacher's mind is socially formed" (Edwards, 2001). This perspective indicates that teacher change is necessarily viewed in terms of social mediational process between individual and the social context. This study examines the interactions between teachers and researchers in order to explore the mediational processes and the aspects of collective understanding, which has emerged from the collaborative workshop. The data were collected from small group activities in a workshop and then analyzed using interactional sociolinguistic approach. Futhermore, activity system was employed to describe the social mediational process. The findings show that participating teachers constructed knowledge through conflict regarding collective understanding. This process of collective understanding was mediated by object, rules, and roles within each activity system. Findings from the study suggest that the sociocultural perspectives to teacher education are essential in understanding how teachers learn to teach and that teachers' professional discourse can play a significant role in teachers' professional development.

The number of military facilities has been rapidly increased due to growing requirement of modernization and military welfare. However, adequate maintenance has not implemented to these facilities. As a result, they are deteriorated quickly and require performance enhancement treatments. There are two ways of performance enhancement, reconstruction and remodeling. Despite the research result that remodeling within the standard remodeling range is more economical, remodeling of military facilities is not considered equivalent to reconstruction as an option of performance improvement. Therefore, derived from the relationship between performance change during life cycle of building and range of remodeling needs, this study tries to propose Remodeling Process Model(RPM) which uses a method to choose remodeling in a Specific Point of Time(SPT) when remodeling is considered more economical than reconstruction. In addition, this study suggests practical service life and functionality evaluation standard together which require to realize the RPM. This RPM make it possible to avoid the cases that facilities which do not have any problem on structural reliability but have low level of functionality miss appropriate remodeling timing and inevitably choose reconstruction as a performance improvement option. It also present the possibility of simple reconstruction / remodeling decision-making for facility managers who administrate building having various type, compilation and elapsed time. Consequently, this process model focusing on remodeling more may contribute to reduce resource waste caused by reconstruction.

Modern high technology has developed from a printing type-oriented culture to sight and hearing-oriented one. Such changes helped raise users' interests and desires on being seen and heard, encouraging research for various usages and types. In particular, with the common use of high speed Internet and firmer standing of Internet as advertising media, Internet banner advertisement has been growing twice as much as the previous year, every year. With this accelerated development of multimedia Kinetic Typography has been used for a variety of forms. During this series of process, the most important one is the expression of the movement of Kinetic Typography. Information able to obtain from the existing way of reading became transferred to the process of multi-dimensional process of obtaining such as seeing and hearing. Accordingly, more effective expression with interesting factors considered together with more activeness for users' obtaining information through Internet, can expect more positive effects. Towards this goal, more various new tries should be made for Internet banner advertisement. In particular, with the larger role in Kinetic Typography to play the role of users' reading for information obtainment, the principles & factors of expression for Internet banner advertisement would be studied, and expression types and structure would be considered, and data from them would be collected and analyzed, to suggest the direction of development.

The semiconductor industry is one of the key industries of Korea, which has continued growing at a steady annual growth rate. Important technology for the semiconductor industry is high integration of devices. This is to increase the memory capacity for unit area, of which key is photolithography. The photolithography refers to a technique for printing the shadow of light lit on the mask surface on to wafer, which is the most important process in a semiconductor manufacturing process. In this study, the width and step-height of wafers patterned through this process were measured to ensure uniformity. The widths and inter-plate heights of the specimens patterned using photolithography were measured using transmissive digital holography. A transmissive digital holographic interferometer was configured, and nine arbitrary points were set on the specimens as measured points. The measurement of each point was compared with the measurements performed using a commercial device called scanning electron microscope (SEM) and Alpha Step. Transmission digital holography requires a short measurement time, which is an advantage compared to other techniques. Furthermore, it uses magnification lenses, allowing the flexibility of changing between high and low magnifications. The test results confirmed that transmissive digital holography is a useful technique for measuring patterns printed using photolithography.

Background: Although the importance of pharmaceutical care service has been growing to meet the needs of customers with the improvement of clinical and humanistic outcomes, there was not a systematic strategy to promote research in Korea. The aim of this study was to suggest the core agendas for pharmaceutical care services research and development (R&D) considering priorities. Methods: Based on desk researches, we developed R&D agendas for the needs of improving pharmaceutical care services in the area of institution, community, and public health. To determine the priority of agendas in developing pharmaceutical care service, analytic hierarchy process (AHP) analysis was performed by the 14 experts. Criteria and subcriteria were assessed for significance by pairwise comparisons. Then, agendas were evaluated for importance according to each subcriteria, and rank ordered considering the weight calculated by multiplying the importance scores of the criteria and the subcriteria. Results: We derived 25 agendas including 13 for institutional pharmaceutical care service, 8 for community pharmaceutical care service, and 4 for public-health related pharmaceutical care service. AHP model was constructed based on 4 criteria and 8 subcriteria by a hierarchical structure. From the AHP survey, the 'Development of pharmaceutical care service for metabolic and chronic disease' agenda accounted for the highest priority. Conclusion: We have developed the R&D agendas of the pharmaceutical care service which should be promoted. The results should be utilized by the government to nationally support the development of the standards and relevant regulations related to pharmaceutical care services in Korea.
