Since the revised enforcement ordinance of the broadcasting legislation, Product Placement that was introduced in May, 2010 has expanded the stable income of broadcasting contents and broadcasting advertising industry, and improved the quality of the broadcasting contents and its service. However, as a result of Product Placement enforcement for the past 3 months, it reveals many problems, and is blamed for being unable to meet the intent of the law. Accordingly, Product Placement is not established properly. Thus, it is required to improve the detailed action plan for revitalization of Broadcasting Contents and Broadcasting Advertising Industry as originally intended. For example, the outsourcing production company involved in producing programs like dramas and the broadcaster have failed to reach negotiation on distributing proportion and it is keenly in need of its related study. This study is to cover the current status and the problems of introducing Product Placement, and is expected to provide the policy implications and the practical lessons. However, it displays limits that it ends in exploring and policy debate. It is henceforth expected to continue various studies of measuring the effectiveness, strategy, creative, and so forth based on discussion of introducing Product Placement.

The purpose of this study was to investigate the influence of the leadership of the top-leader and the mid-level leader on the care burden of care workers. A survey was conducted on 400 care workers working in long-term care facilities in Seoul and Gyeonggi area. We conducted a hierarchical regression analysis to grasp the effect of the leadership of top-leader and mid-level leader on the care burden of care workers. Monthly income of care workers was significantly associated with care burden. In next step, the leadership of the top-leader affected the care burden of care workers. But, In last model 3, only the leadership of mid-level leader affected the care burden with monthly income. This findings suggested that it is urgent to stabilize the salary level of care workers, and to develop the leadership skills of mid-level leader. The improved leadership of Mid-level Leader will help to reduce jop chaos for care workers.

The information delivery and transmission media(DID or PID) market is making remarkable growth as the high-speed networks are spreading and LCD/LED TVs are more and more popularized, and display devices are increasingly large and high-definition. In addition, the popularization of smart devices and the expansion of the information delivery and transmission media market make a demand for N-Screen in content service. Colleges and universities have installed and operated various types of DID to promote their schools and departments and deliver information about them, still remaining in the level of media content implementation. So, we implement and evaluate a next-generation electronic bulletin board for each department that allows for interactive N-Screen communication based on the integration of smart phone and internet. This board enhanced efficiency as supporting N-Screen, inserting and deleting the contents at real time and offering bidirectional communication.

The main objective of study was to determine the optimum level of bus service by bus route types for the effective improvement of bus route operating in semi-public transportation management. In pursuing the above, this study proposed to classify by bus route types based on publicity, profitability and potentiality. Using this methods of the classification, 113 bus routes in Busan were classified into bus routes of 8 types. And this study proposed desirable management of bus route operation according to 8 bus route types considering 9 bus operating characteristics such as bus route distance, operating number, state of passing through the CBD and so on. For proposing the desirable management, it was to do a statistical analysis of PCA(Principal Components Analysis) and to abbreviate 9 variables to 3. And it was drawn a conclusion effectively by making comparison between 8 bus rout types and 3 bus operating characteristics.

According to the purpose of applications, the application program will utilize the most suitable data model and 3D modeling data would be generated based on the selected data model. In these reasons, there are various data sets to represent the same geographical features. The duplicated data sets bring serious problems in system interoperability and data compatibility issues, as well in finance issues of geo-spatial information industries. In order to overcome the problems, this study proposes a spatial data fusion method using topological relationships among spatial objects in the feature classes, called Topological Relation Model (TRM). The TRM is a spatial data fusion method implemented in application-level, which means that the geometric data generated by two different data models are used directly without any data exchange or conversion processes in an application system to provide indoor LBSs. The topological relationships are defined and described by the basic concepts of IndoorGML. After describing the concepts of TRM, experimental implementations of the proposed data fusion method in 3D GIS are presented. In the final section, the limitations of this study and further research are summarized.

Income is a vital aspect of economic life. Knowing what their income will help people create budgets that allow them to pay for their living expenses. Income data is used by banks, stores, and service companies for marketing purposes and for retaining loyal customers; it is a crucial demographic element used at a wide variety of customer touch points. Therefore, it is essential to be able to make income predictions for existing and potential customers. This paper aims to predict employment earnings or income based on history, and uses machine learning techniques such as SVMs (Support Vector Machines), Gaussian, decision tree and DCNNs (Deep Convolutional Neural Networks) for predicting employment earnings. The results show that the DCNN method provides optimum results with 88% compared to other machine learning techniques used in this paper. Improvement of the data length such PCA has the potential to provide more optimum result.

There are some problems in TMA. There are no databases in Korea which can be independently and specially analyzed the TMA results. Even there are some medical databases, some of them are low level databases which are related to TMA, so they can not serve medical services to patients as well as doctors. Moreover, TMA results are based on the database of american health and mineral standards, it is possibly mislead oriental, especially korean, mineral standards. The purposes of this paper is to develope the first Intelligent TMA Information System(ITS) which makes clear the problems mentioned earlier ITS can analyze TMA data with multiple stage decision tree classifier. It is also constructed with multiple fuzzy rule base and hence analyze the complex data from Korean database by fuzzy inference methods.

Recently, the IEEE 802.11 working group has announced a new distributed MAC called EDCF to provide service differentiation among traffic classes. With the increasing demand for supporting Quality of Service in IEEE 802.11 wireless LANs, the EDCF is now attracting many researchers' attention due to its practical worth as a standard mechanism. In this paper, we focus on the analytical approach to evaluate the performance of the EDCF. An analytical model is developed to estimate the throughput of the EDCF in saturation (asymptotic) conditions. Extensive simulation studies have been carried out for the validation of the analysis, and they show that it estimates the throughput of the EDCF accurately By utilizing the analytical model, we evaluate the performance of the EDCF. Specifically, we concentrate on discovering the characteristics of the EDCF Parameters, such as CW/Sub min/, CW/Sub max/ and AIFS, in the way that they influence on the performance of the EDCF.
