In this study, Private investigation in South Korea, while gone through so far of politics, the process of social change, a positive feature, without evolve, insufficient growth and security services of the business burden of national judicial institutions, detective industry international of the negative vicious circle, such as the acquisition of drop and expedient information of competitiveness is continuously induced it is a reality. It is, therefore, to the proposal, such as the following. First, it must be able to use the term "detective". Secondly, in order to verify the validity of this system, after introducing the first private sphere, in accordance with the stepwise its necessity, it is desirable to extend the operational range of the public area. Third, to have a country of qualification to private research workers, will be managed directly from the country is ideal. Fourth, we must also seek plan to specialize the designated educational institution as a commissioned education institution to institution with a faculty and facilities that are specialized. Fifth, the National Police Agency must manage and supervise the private investigation business. Sixth, the legislative form to amend the current security law, as a kind of private security, must be introduced by adding a private trillion business. Therefore, in order to complement the limitation of such studies, additional subsequent research has if it is not carried out.

Existing researches on tax efficiency of environmental taxes mostly focuses on taxes imposed on the consumption process of the final output, or goods that create pollution during the input process of intermediate goods. The assumption here is that there is a significant relation between the consumption of polluting goods and the pollution itself. However, in reality they are not identical. This signifies that the above assumption may distort the actual results. This study classifies environmental tax into two different forms, output tax and emission tax. Theformer is the tax that is imposed on the consumption of polluting goods, while the latter is directly levied onto the emission of pollution. It then compares the efficiency of these taxes through the computational general equilibrium simulations. After analyzing the simulation, it was proven that the direct imposition on pollution, or environmental tax as emission tax, was more effective in terms of tax efficiency. Furthermore, these results were revealed as irrelevant to the assumption of homotheticity in utility function. Thus, if market-distortionary tax already exist, then the effectiveness of revenue neutral environmental tax reform will be sensitive to the assumption of homotheticity for utility function. However, environmental taxes as emission taxes have been shown to be more effective in tax efficiency than output taxes.

The main purpose of this paper is to identify the characteristics of the private educational institute street in Pyengchon, Anyang-si by analyzing the locational determinants of private education institute, the spatial range of it educational service and the spatial behaviour of private education institute students. The research has concerned with the locational determinants of private educational institutes in Pyengchon. Its main locational determinants are a reputation as a region of private educational institution street, access to large residential areas and rents. Also, it has considered the spatial service range of private educational institutes. To this end, it divided private educational institutes into three hierarchies from first sized to third sized private educational institute. The educational service of first sized institutes delivers to within a 10km radius of them, including Suwon. In particular, the service of them is concentrated on within a 6km radius of them. The educational service of second and third sized institutes both delivers to within a 6km radius of them. The service of second sized one is concentrated on within a 2km radius of them, and third sized one is within a 1km radius of them. What is more, it has analyzed the spatial behaviour of private educational institute students.

There have been growing concerns that Korea's products keep losing their international competitiveness. It is necessary to restore strong muscles of manufacturing sectors. Together, efforts must be made to strengthen the competitiveness of service sector. While wide consensus has been reached on the necessity that Korea's service sector needs overhaul for stronger global competitiveness, it is rather difficult to witness any remarkable improvements. Insufficient performances might result from the protection of the captive markets by the interested parties. The research starts from the proposition that the introduction of MDP will bring down the barriers between the segmented services and promote competition. We provide theoretical analyses and report better performances of major countries which introduced MDP in their soils. Considering the reality, we propose that in the foreseeable future, a MDP in the areas of tax, law and accounting be introduced in Korea because these areas seem to create least conflicts of disciplinary duties due to public purposes. Broader MDPs in other areas may take some more time. There exist, however, some limitations. As MDP has not been officially introduced in Korea, it is almost impossible to directly compare the performances between the pre- and post-MDP in Korea. Data scarcity of business performances of companies also limits the study.

This study attempted to understand the characteristics of images of scientific experiments represented and consumed on YouTube, a representative of today's new media. In particular, this paper analyzes the case studies of YouTube's hydrogen peroxide decomposition experiment based on Baudrillard's theory of Simulation and Simulacra, which discusses the strong status of images and the ambiguity of the boundary between virtual and reality. A total of 14 YouTube videos related to hydrogen peroxide decomposition experiments were analyzed. In those videos, hydrogen peroxide decomposition experiments were typically conducted with several signs representing scientific experiments, but the most important sign in the videos were bubbles produced through experiments. For more public consumption of the content, the bubbles resulted from hydrogen peroxide decomposition reproduced in YouTube have been transformed into a more spectacular image as 'super-huge' and 'explosive' bubble. Considering the influence of new media that can be accessed by students anytime and anywhere, it is positive that science experiments in new media enhance students' intimacy and access to science. At the same time, however, it is also important to note the danger that the purpose of scientific experiments will be limited to only 'showing specular images', due to the nature of new media, which mainly deals with immediate and superficial images. Furthermore, this study argues that improving students' science media literacy is required to critically examine the science-related images represented in the new media based on understanding the characteristics and limitations of new media that deeply affect daily life.

Due to the rapid development in information technology, countries of advanced information technology and multi-national information communication industries have expanding their invesment in constructing a cyber territory or a cyber city, and even a cyber globe that combines the real world with the cyber world. As such, in order to keep up with the competition with other countries to secure the Invisible Continent, Korea cannot afford to fall behind in the preparation and efforts to construct a cyber territory. Therefore in preparation for the inevitable establishment of a cyber territory, this study defined the concept of a cyber territory clearly and proposed a promotional strategy needed by the government for the establishment of a cyber territory. A cyber territory is 'the dynamic second territory that realizes various values in various aspects through organically combining innumerable active bodies in a surreal space and that are created by systematically and optimally connecting the physical topographical space and activity of the first nation to the cyberspace'. To explain further, a cyber territory is defined as another simulated space not only to manage the land systematically and deal with administrative services far the greater population, but also to contain economic activities of corporations and the citizens' everyday lives in a virtual reality by digitizing the entire territory including even the sea. In order to establish such cyber territory, it is necessary to revise related laws and policies, to foster related technology and industry as a main engine for national development, to promote public awareness, and to train related human resources.

Because the result of environmental pollution of one state is not limited to the national border but spills over into neighboring countries or global environment either directly or indirectly, international discussions on environment are crucial in domestic environmental law and policy. International environmental law demands differential obligation between developed and developing countries in the principle of 'common but differentiated responsibility'. The common but differentiated responsibility is the principle that draws distinction between developed and developing countries about global environmental issues, while recognizing the common responsibility of environmental protection for all nations. Environmental technology transfer or financial support from developed countries to developing countries, for example, has been discussed. The problem is the status of Korea. Korea's international environmental policy will be different by the distinction of responsibility for international environmental protection according to the status of developed and developing countries. International communities have never established a clear standard distinguishing developed from developing countries in any international laws. The WTO entrusts each country to decide whether it is a developing country or not. In the international environmental law, the status of a country is determined by the ability to negotiate. The status of Korea, thus, cannot be fixed in general international law. Rather, the Korean government is able to choose its own status strategically, It can be a policy choice to insist that Korea's developing country so as to reduce the burden of international responsibility. But, considering an economic indicator and environmental pollution indicator at which Korea ranks about 10th, the reality of Korea is much closer to a developed country. Positive policies such as development of environment-friendly technologies and products should be preferred to defensive assertion of developing country.

The availability and efficient use of the feed resources in Asia are the primary drivers of performance to maximise productivity from animals. Feed security is fundamental to the management, extent of use, conservation and intensification for productivity enhancement. The awesome reality is that current supplies of animal proteins are inadequate to meet human requirements in the face of rapidly depleting resources: arable land, water, fossil fuels, nitrogenous and other fertilisers, and decreased supplies of cereal grains. The contribution of the ruminant sector lags well behind that of non-ruminant pigs and poultry. It is compelling therefore to shift priority for the development of ruminants (buffaloes, cattle, goats and sheep) in key agro-ecological zones (AEZs), making intensive use of the available biomass from the forage resources, crop residues, agro-industrial by-products (AIBP) and other non-conventional feed resources (NCFR). Definitions are given of successful and failed projects on feed resource use. These were used to analyse 12 case studies, which indicated the value of strong participatory efforts with farmers, empowerment, and the benefits from animals of productivity-enhancing technologies and integrated natural resource management (NRM). However, wider replication and scaling up were inadequate in project formulation, including systems methodologies that promoted technology adoption. There was overwhelming emphasis on component technology applications that were duplicated across countries, often wasteful, the results and relevance of which were not clear. Technology delivery via the traditional model of research-extension linkage was also inadequate, and needs to be expanded to participatory research-extension-farmer linkages to accelerate diffusion of technologies, wider adoption and impacts. Other major limitations concerned with feed resource use are failure to view this issue from a farming systems perspective, strong disciplinary bias, and poor links to real farm situations. It is suggested that improved efficiency in feed resource use and increased productivity from animals in the future needs to be cognisant of nine strategies. These include priorities for feed resource use; promoting intensive use of crop residues; intensification of integrated ruminant-oil palm systems and use of oil palm by-products; priority for urgent, wider technology application, adoption and scaling up; rigorous application of systems methodologies; development of adaptation and mitigation options for the effects of climate change on feed resources; strengthening research-extension-farmer linkages; development of year round feeding systems; and striving for sustainability of integrated farming systems. These strategies together form the challenges for the future.

In the cloud computing environment, cloud service users purchase and use the virtualized resources from cloud resource providers on a pay as you go manner. Typically, there are two billing plans for computing resource allocation adopted by large cloud resource providers such as Amazon, Gogrid, and Microsoft, on-demand and reserved plans. Reserved Virtual Machine(VM) instance is provided to users based on the lengthy allocation with the cheaper price than the one of on-demand VM instance which is based on shortly allocation. With the proper mixture allocation of reserved and on-demand VM corresponding to users' requests, cloud service providers are able to reduce the resource allocation cost. To do this, prior researches about VM allocation scheme have been focused on the optimization approach with the users' request prediction techniques. However, it is difficult to predict the expected demands exactly because there are various cloud service users and the their request patterns are heavily fluctuated in reality. Moreover, the previous optimization processing techniques might require unacceptable huge time so it is hard to apply them to the current cloud computing system. In this paper, we propose the cloud brokering system with the adaptive VM allocation schemes called A3R(Adaptive 3 Resource allocation schemes) that do not need any optimization processes and kinds of prediction techniques. By using A3R, the VM instances are allocated to users in response to their service demands adaptively. We demonstrate that our proposed schemes are able to reduce the resource use cost significantly while maintaining the acceptable Quality of Service(QoS) of cloud service users through the evaluation results.

The purpose of this study was to investigate the conceptions toward ICT in students who are currently enrolled in giftedness in invention classes. A total of 147 students at the junior and high school level responded to a 33 item questionnaire. Results show that these students consider ICT as very important and that it will become more important in the future. They also indicated that they frequently use ICT in their studies and also in their work. But a majority of the students considered their level of expertise in the ICT area as 'moderate', and their application of the programs as 'elementary'. Thus it can be assumed that these students did not have enough opportunity to learn ICT related skills. These students also expressed the desire to receive systematic instructions in the ICT area beginning from simple application to program development. The students thought that ICT skills need to be incorporated into the invention education to lead to better inventions. Considering the fact that the ICT area is becoming increasingly important and that Korea is considered a representative country in ICT, the reality of ICT education does not stand up to expectations, and the creative software development capacity is relatively low. Therefore, there is a need to incorporate ICT contents into the education for the giftedness in invention classes, and also to form connections with software development and invention education.
