Many countries have implemented EA as a core tool for planning and managing IT resources. Due to its importance, there have been many studies for the successful implementation of EA. However because most previous studies simply focused on either a certain time horizon as a cross sectional study or a list of success factors, they failed to raise fundamental issues investigating inherent difficulties or efforts to overcome. This research conducted a case study based on interviews with EA experts and derived five practical guidelines for the successful EA implementation. Simultaneously we propose a future research model for an empirical validation based on current findings.

Enterprise Architecture (EA) is known as a means to solve IT management problems. In 2005, the South Korean government introduced it and required each agency to develop a variety of architectural products. Such an early-stage EA effort turned out to be not very effective because those products were hardly of use for pan-government IT governance. Realizing these problems, the Lee Myung Bak government has decided to change its direction so that EA products would also be utilized at pan-government IT decisionmaking. After reviewing the early stage of EA effort, we in this study describe such a transition. Future directions of EA efforts are also discussed at the end.

Recently, EA has been introduced in the Korean government as a tool for improving both IT management and IT investment. However, EA has been superficially used at the conceptual level without any efforts for facilitating it. As a result, it seems that any substantial outcomes from using EA could be hardly realized. This study suggests EA Service Model as a framework for facilitating the use of EA and then generating benefits. The purpose of EA Service Model is to provide a framework with which information and data can be linked, interconnected and shared in the whole process of IT management. It is expected that EA Service Model will possibly make a contribution to improving IT management. Empirical Analysis shows that key factors of EA Service Model make significant effects on improving the IT management, proving practical value and the validity of the model.

The Korean military is aware that EA(Enterprise Architecture) is an important tool for transforming national defense and building Korean NCW, being developing the Ministry of National Defense Enterprise Architecture(MND-EA). However, unlike the importance of MND-EA, they are building MND-EA without the explicit EA governance system Many researchers have emphasized that it is difficult to develop the useful EA without EA governance. In this study, we present the EA governance framework for implementing the effective MND-EA. Through the investigation of the state of EA development and EA governance of home and abroad public institutions, we recognize the importance of EA governance, identifying the EA governance components. We set up the basic governance model consisted of principle, organization and process, designing the MND-EA governance framework by mapping the model to governance scope and target. The proposed governance framework provides direction for explicit and formal MND-EA governance system.

EA, efficient and hierarchical Information Resource Management(IRM) tool of Korean public agencie is one of the core of carrying forward the e-Government initiative. The objective of the paper is to study empirically whether using EA Governance for Controlling EA is related with their EA competency or not. the 190 person in charge of Information System service division are included for analysis. The various hypotheses established are validated by structural equation in SPSS and AMOS 18.0. The results shows that EA management and EA utilization of EA competency level was affected by EA Function, EA Organization and EA Human Resource of exogenous variable EA Governance but EA implementation level was not affected by EA Organization and EA Human Resource. also we investigated that the EA management level of endogenous variable EA competency was affected positively by EA implementation level and the EA utilization level of was affected positively by EA management level by stages.

Enterprise Architecture has become a key tool for transforming business process, data, IT and application resources. The "Efficient Adaptation and Management of Information System Act" was established to support the planning and development of the information system in order for the public sector to adopt Information Technology Architecture (EA) into its organization through the act. Until now, the study of EA has been mainly focused on concepts, methodologies and success factors for the implementation of EA. User involvement, which is one of the critical factors in adopting information systems, has been rarely studied in the field of EA research. The purpose of this study is to identify the effects of user characteristics on user involvement in EA implementation. After discussing intrinsic motivators and situational motivators as predictors of user involvement, a research model were developed and tested using survey data. The results showed that among intrinsic motivators, perceived competence had a strong positive effect on user involvement. Some implications were discussed for implementing and utilizing EA for public agencies.

Refining the monitoring and evaluation reporting is an important thing in e-Government. Indonesia which has had e-Government roadmap since 2000, has not had the systematic mechanism to monitor and evaluate e-Government in which the report can be easily accessed by the public and used to be the best practice to improve other e-Government implementation. Enterprise architecture (EA) has the major objective to straighten an enterprise to its necessary requirements. It can be used to propose the required system and that was the purpose of this paper. It was started by reviewing the literature about e-Government monitoring and evaluation, using quality of service as the means, and understanding TOGAF as one of EA framework. The second step was comparing EA and the evaluation of e-Government in Korea and Indonesia to get the best practices. And the last step was creating EA for the monitoring and evaluation reporting system based on Korea and the literature reviewed. It is expected that the formulized EA can be a tool to improve e-Government implementation in Indonesia.

The introduction of Strategic Environmental Assessment (SEA) has strengthened and extended the value of Environmental Impact Assessment (EIA) as a fundamental tool for sustainable development. In particular, SEA helps to overcome the limitation of project EIA as a stand alone approach that is applied relatively late in the decision making cycle. SEA is applied to proposals of policy, plan, and/or programme when major alternatives are open. In Korea, similar to SEA, the Prior Environmental Review System (PERS) was introduced to overcome the limitations of the EIA, by checking the environmental impacts on major policy and administrative actions in the early stage of decision making process. SEA appears in various national, regional and international laws. SEA is addressed specifically in the UNECE SEA protocol to the Espoo Convention on Environmental Impact Assessment in a transboundary context, as well as the European Commission SEA Directive (2001/42/EC). SEA is a valuable tool for integrating sustainability decisions into country's policies, plans and programmes. This paper reviews the policy direction for implementation of the SEA and efficient Environmental Assessment (EA) through integration of the PERS and the EIA.

This paper explores how the provided information from Enterprise Architecture (EA) affects the activities to for performing IT projects. The IT projects analyzed in this paper are projects to for developing and maintaining Korea Customs' UNI-PASS. This research was conducted based on surveys to demonstrate the effects of the information from EA on activities for IT projects. Information from EA is categorized into propriety, sufficiency and consistency. Activities for IT projects are defined as management, participation, communication, requirement management and human resource. Correlational analysis is used to measure the effects of the inf ormation on the defined activities. The analysis, which verifies the provided information by EA, does not have meaningful correlation with project management nor human resource. For public officials in charge, Sufficiency of the information produces a positive effect on decision making. For operation company, consistency of the information encourages utilization of the resources required for the project. This research suggests that strategies for performing IT projects with EA information that can support the verification of characteristic environments of each project and performance of vital activities required by the participants' roles will ensure the success of government IT projects.

Bacteriophages, bacteria-infecting viruses, have been recently reconsidered as a biological control tool for preventing bacterial pathogens. Erwinia amylovora and E. pyrifoliae cause fire blight and black shoot blight disease in apple and pear, respectively. In this study, the bacteriophage phiEaP-8 was isolated from apple orchard soil and could efficiently and specifically kill both E. amylovora and E. pyrifoliae. This bacteriophage belongs to the Podoviridae family. Whole genome analysis revealed that phiEaP-8 carries a 75,929 bp genomic DNA with 78 coding sequences and 5 tRNA genes. Genome comparison showed that phiEaP-8 has only 85% identity to known bacteriophages at the DNA level. PhiEaP-8 retained lytic activity up to $50^{\circ}C$, within a pH range from 5 to 10, and under 365 nm UV light. Based on these characteristics, the bacteriophage phiEaP-8 is novel and carries potential to control both E. amylovora and E. pyrifoliae in apple and pear.
