This study aims to develop the model of needs analysis for lifelong education program in order to verify social needs as well as personal needs. The overall process of this study is as follows. Firstly, a questionaire based on six mode classification of lifelong education program was invented in order to apply to program development. Secondly, a questionaire was designed to evaluate personal needs and social needs simultaneously. Thirdly, t-test, needs analysis of Borich model, and the Locus for Focus model were conducted with a view to analyze the difference between personal needs and social needs. As a result, there showed the categories of education which are high in both personal and social needs, whereas a category like certification program is higher in social needs rather than in personal needs. The results represent the necessities of promoting programs which are high in social needs even if there is no personal needs. Therefore the needs survey and the needs analysis need to be conducted to find out not only personal needs but also social needs.

Paradigm shift in government services means the evolution to the service with active participation based on information technology. Opening public information proceeds to an extent that private sector participation can be a basis and driving force, and extends to a stage that free and practical use is possible for private sector. Therefore, the government is preparing for legal and institutional foundation for various fields. The government needs to build open network from user-oriented point of view rather than provider-centric point of view, improve communication, and change the way of working due to the fact that flexible and rapid business process is required. It is time to prepare development plans for public the functions of platform-type government that public sector can participate in the role of government, create new value, and give rise to innovation in order to change the functionality of the government and meet the new needs of citizen. This study tries to analyze platform-type government and to study efficient role allocation for sharing resources including informant and system between the government and the private sector, focusing on innovation of public information sharing.

Korean society has been recently promoting the restoration of coastal wetlands. These efforts might become the basis of a policy framework that compensates for the limitations of a regulation-oriented policy such as the designation of Marine Protected Areas (MPAs). The shift in government policy could contribute to strengthening the socioeconomic infrastructure of coastal development through the accumulation of ecological capital. Although our scientific efforts and social demands in regard to the ecological restoration of the coastal wetlands have increased during the past years, the bases for restoration in Korea requires that scientific, technological, financial, social and legal aspects be enhanced. The present study re-examined the concept and attitudes behind coastal wetland restoration in the light of changing circumstances in Korea. Herein, we first defined coastal wetland restoration as "An act of recovering the functions of the ecosystem of coastal wetlands to a state that resembles conditions prior to being damaged." Next, this study discussed the limitations and future directions of such restoration efforts based on the descriptive analyses of recent restoration practices from social, economic, and technological aspects. Finally, we suggest future policy directions regarding coastal wetland restoration on the basis of a PFST (Policy, Financial, Social, and Technological) analysis; 1) re-arranging legal mechanisms, 2) setting multi-dimensional restoration goals, 3) establishing a multi-discipline- and convergence based R&D system, 4) linking spatial management and local development to the restoration, 5) building restoration governance at the local level, 6) implementing an ecosystem service payment system, and 7) applying test-bed projects in accordance with proper directions.

In Korea, the act for promoting use of the public data has been enforced since 2013. The Key Government 3.0 Strategy was established for providing the public data as an obligation of public authorities for users to use them free of charge. The aim of open public data and using them targeted by the government is creation of a solution for vitalizing the economy by using the public data. However, the reason for low usability and tangible outcomes despite unlimited provision of open government data is as follows. That is, it is essential to address the issue of difficult software technology required to access public data for using the data. However, with the open API method currently provided, the development procedure is not easy even for IT students or specialized software developers. Therefore, strategies for each step ideal for the level of developers are required to vitalize applications based on the public data and developed by ordinary users. Two strategic methods can be used for facilitating the use of public data and applications developed by ordinary users suggested in this paper on the basis of the public data portal organized by the Ministry of the Interior and provided to all ordinary users. That is, they are applications developed in the web browser environment and those developed in the PC environment. They allow ordinary users to develop and distribute applications based on the public data to contribute to enforcing the policy for facilitating the use of public data of the government just with basic training and basic knowledge from the training without using program coding knowledge of open API which requires the knowledge of development professionals.

As unrenewable energy resources have depleted over the years, the demand for renewable energy has increased promoting research for more effective methods to produce renewable energy. The field of fuel cell development, specifically microbial fuel cells (MFCs), has developed because of the dual performance potential of the technology. MFCs convert power by facilitating electrode-reducing organisms such as bacteria (microbes) as a catalyst to produce electrical energy. MFCs use domestic and industrial wastewater as fuel to initiate the process, purifying the wastewater as a result. Proton exchange membranes (PEM) play a crucial role in MFCs as a separator between the anodes and cathodes chambers allowing only protons to effectively pass through. Nafion is the commercially used PEM for MFCs, but there are many setbacks: such as cost, production time, and less effective proton conductivity properties. In this review there will be largely two parts. Firstly, several newly developed PEM are discussed as possible replacements of Nafion. Secondly, MFC based on PEM, blended PEM and composite PEM are summarized.

The advent of multi-cultural society and multiracial nation is a new change of the times and a new phenomenon. In this social change, a need for a new theory and a new policy appropriate for Korean conditions is surfacing. In case of Japan, they have been changed into stable multi-cultural society by establishing various policies. An investigation on the changing process of policy in Japan has a great significance, we think. This study compared and analyzed the reason of promoting multi-cultural policies, changes of the related laws and institutions and the policies between Korea and Japan, investigated characteristics and differences between them, deduced implications and presented a new theory for multi-cultural policy appropriate for Korean conditions. In order to establish a new multi-cultural policy in Korea, firstly, acceptance of diversity and mutual recognition, secondly, establishment of policy direction through social consultation and thirdly, establishment of multi-cultural regulations followed by reestablishment of economical and political regulations should be required.

Polymethyl methacrylate (PMMA) is concerned with promoting oral infection due to its low antibacterial activity. To overcome this, the nanoparticles of Ag-MSN, nGO, and CNP were mixed with MMA liquid in a weight ratio of 0, 0.25, 0.5, 1.0, 2.0% compared to resin powder using Orthocryl from Dentarum, a calibration resin, and then instructed by the manufacturer. Accordingly, a specimen for calibration was prepared by mixing PMMA: MMA (1.2: 1) ratio, and physical properties of the calibration resin, antifungal experiments, and statistical analysis were performed. As a result of antibacterial experiments, the antibacterial properties of Ag-MSN increased. In nGO, the antibacterial adhesive effect increased hydrophilicity, not a change in surface roughness. The higher the CNP concentration, the higher the antibacterial activity. This suggests its potential usefulness as an antibacterial dental material for orthodontic devices and temporary restorations.
