Blockchain and its infrastructure technology have expanded rapidly in the last decade and are in high demand, but there is a lack of comprehensive studies on those platforms. Blockchain is a new technology based on the distributed digital ledger system. Decentralized trust is one of the key factors behind the blockchain-based system. Transparency of such a system is better than a conventional centralized ledger system. By using a blockchain-based transaction system, any business organization can harness key benefits like data integrity, confidentiality, and anonymity without involving any third party in control of the transactions. Since the blockchain is used in numerous applications and the horizon is expanding at an unprecedented pace. So, there is a need for an introducing and reviewing of blockchain platforms. In this paper, we have reported a review on existing contemporary blockchain platforms. In particular, From the existing studies, we have identified eighty blockchain platforms and the majority of them have a lack of technical details. To provide the researchers a comprehensive introducing on blockchain platforms to perform a broad guideline for future research and investment in the blockchain domain.

And then this study verified the validity of hypothesis in terms of environmental design perspective and suggested layout of recharging station model. 21 recharging stations in Korea and station operation cases of 7 countries were examined. Except for the USA, the reality of electric vehicle recharging station today is the 1st proving stage focusing on the infrastructure construction of electric vehicle recharging station. It focuses on performance of recharging facility, use efficiency and operation environment of electric vehicle. About the effective waiting time of the user to use it should be studied. The current conditions of recharging station are as follows: Lack of independent recharging space, lack of facility that reduces external effect of recharging space, and lack of lounge for users during the waiting time. These three are essential factors constructing a suggesting model after basic layout, which needs proper measurement on the long recharging time and long waiting time. The essential factors are applied to electric vehicle recharging station layout so that users might use 'digital refresh" i.e. lounge and information contents service during the waiting time which provides convenience of recharging and emotional space with users. Such upgrade recharging station environmental model might resolve the burden of long recharging time which may contribute to the popularization of electric vehicles.

Vietnam is gaining much attention as an attractive emerging market that can replace BRICs for the corporations who are destined to always look for a new market in order to secure competitive powers in the global market. The reason for Vietnam's becoming an attractive place for production is that much uncertainty has been found in China, which has been the traditional country that absorbed the most amount of capital investment. Also, the favorable conditions of Vietnam market itself and the environmental changes such as the open-door policy of Vietnam government attract the investment of Korean companies, and Korea currently holds the most amount of cumulative investments in Vietnam. However, it is necessary to remember that Vietnam is still a socialist nation, and many required components for corporate activities are not sufficiently provided in Vietnam market. Also, many unstable environmental factors exist such as the lack of infrastructure, the lack of many required institutions, the prevalent corruption, the excessive processing time and cost for adjusting the investment, the lack of advanced work force, and the underdevelopment of part and material industry. Therefore, those companies who are planning to invest in Vietnam should take a long-term perspective in planning the investment strategies, carry out a detailed market investigation and analysis in advance, diversify the investment areas and investment sectors, carefully make a joint venture and management, carefully determine the factory location, establish a local agency, make co-investments with the part suppliers, etc.

The various environmental problems that we face on today are basically about environmental quality. Since early 1960s affluent material was produced because of remarkable economic growth by many cooperations. However, for the lack of environmental policy, environmental pollutions has been serious. The central government should transfer the producing and consuming structure to environmental affinity through the regulations for developing Korea as a model of environmental nation which takes an active part in global environmental programme and in which the environment and economy are well harmonized. Moreover, the central government should take the lead in prevention of environmental pollution through the direct policies such as strengthening the discharge limit or setting up environmental basic institutions by securing budget for conserving environment. This thesis emphasize on the public institution among many environmental basic institutions for environmental anti-pollution project. It will find the problems with running those institutions, and will suggest the preview of improvement. Also, it is necessary to investigate of variation trend for inflow and pollutant loading to environmental infrastructure as increased of the diffusion rate as established and maintenance of sewer system. The purpose of this study is to investigate for inflow and pollutant loading to environmental infrastructure, and also to provide the method of efficiently maintenance and management.

Location management is difficult in ad hoc networks due to many features such as the lack of a wired infrastructure, the scarce energy, memory and processing capabilities of nodes, and nodes’ movement which leads to a dynamic topology. These characteristics make the location management schemes designed for mobile cellular networks inefficient for ad hoc networks. New solutions for location management have therefore been proposed in the literature in the recent past. In this paper, a taxonomy of location management strategies is presented; some of the more interesting approaches proposed in the literature are critically discussed, highlighting their advantages and disadvantages.

Right after president Keun-Hae Park's announcement at German Dresden on March 2014, both expectation and skepticism have been raised for the Korean unification. The unification would give a great chance for the economic prosperity in the positive sense. In the negative sense, it would only give a great burden to the Republic's financial status. Comparing the expectation of the unification, there are lack of structured preparation, duplicated and/or overlapped systematic approach, and even the national strategies are diffused. There are several individual research papers, analytical data and information, researches on the industry and technology. However most of the previous researches and findings are unstructured and lack of completeness. It is hard to find out the overall feature of the unification strategy. West German has compassed that it knew very few the reality of East German status. The Korean Government may know much less about North Korea's condition comparing to West German. Before the actual unification in the Korean peninsula, it needs the Grand Plan for the national infrastructure and land utilization of the Korean peninsula. During the development of the Grand Plan for the Korean peninsula, the Asian Global transportation network could be developed at the same time. The German's unification experience can give a great opportunity to the development of the Gran Plan. The data and information, and the previous researches should be classified and structured in a way of systematic arrangement. Since most of investment and budget for the unification come from the Korea, it would be very much beneficial for the Korean people. The openness and early exposures of the Grand Plan for the national infrastructure are considered as mandatory action.
