The High Level Architecture(HLA) for modeling and simulation was developed as means of facilitating interoperability among simulations and promoting reuse of simulations and their components. The purpose of this paper is to provide a summary of the latest release of the HLA concept, supporting utilities and develop the prototyped Transportation Movement Management(TMM) federation. To obtain this goal, the Federation Development and Execution Process(FEDEP) is being applied to development of TMM federation will consist of three federates. This paper outlines the rationale of our approach, describes the application of the FEDEP in the development of the federation, and provides the current status of the federation development. The resulting federation shows complete interoperability among simulation components in the TMM federation and satisfactory simulation outputs. We present a description and process of the federation and the lessons learned with the process utilization for federation development and execution. Furthermore, the issues in establishing a HLA based federation across multiple legacy simulations are discussed.

Development of science technology, computer network and software technology has not only changed various areas of the society, but also brought rapid change in the condition and the way of performing war. Historical lessons learned from the war in Iraq tells that military capabilities corresponding to the new paradigms of war needs to be assured in order to preserve national interest and take victory in future warfare. Thus, the performance in the latest war in Iraq, the estimated performance in future war and the performance of war in the Korean Peninsula has been put together and analyzed to indicate the direction our force should be built and the structure to be improved. Under all circumstances and threats the military must defend our nation and territory. When war breaks out the military must perform it's basic duty to end war by decisive operations. As the saying is "To preserve peace, prepare for war," continuous increase of military strength and improvement of military structure corresponding to the change of national security environment and weapon system is necessary.

A Requirement statement validation process is suggested which was established and applied to the rolling stock development project of the Korean Railway Research Institute. The validation process includes team organization, selection of validation criteria, development of validation template, education of team members, validation, construction of database and management of requirement change. Many defects in the specification of requirement were found to be associated with the problem of non-uniqueness, describing solution instead of problem, ambiguity and redundancy. This paper described detailed activities at each step of the validation process and lessons learned from these activities.

A Systematic Wealth Management Framework (SWMF) was developed as a private banking management tool to enable more integrative personal finance management of personal wealth. It is a reference model that provides an unified framework for development, operation, and management and makes provision for personal financial services in today's complex financial environment. This study suggested some practical results from banks and insurance companies that have established SWMF as the differentiation business strategy for wealthy customers. The focus of this manuscript is on capturing the methodological approach most financial institutions in Korea adopted to execute new e-finance planning and implementation based on the SWMF. The alignment between the wealth management business goals and information system architecture at an organization constitutes the main theoretical basis of the study. Relevant discussions are made on the wealth management framework as a general business model for financial industry, on the functional relationship between new information systems and business organizations. Finally, lessons learned from the SWMF implementation are discussed.

The Tohoku earthquake (Mw9.0) occurred on March 11, 2011 and caused a large tsunami. The Fukushima Dai-ichi NPP (F1-NPP) were overwhelmed by the tsunami and core damage occurred. This paper describes the overview of F1-NPP accident and the usability of tsunami PRA at Tohoku earthquake. The paper makes reference to the following current issues: influence on seismic hazard of gigantic aftershocks and triggered earthquakes, concepts for evaluating core damage frequency considering common cause failure with correlation coefficient against seismic event at multi units and sites, and concepts of "seismic-tsunami PSA" considering a combination of seismic motion and tsunami effects.

Substation Automation System (SAS) based on IEC 61850 is becoming more and more reality in applying power systems. As well, the development of various engineering tools and the convergence with diagnostic systems are underway. To reflect recent advancements in SAS technology, the Korea Electric Power Corporation initiated a 154kV SAS pilot project and a smart power grid business in 2010. In this paper, the authors will summarize the overview and the lessons learned in applying the IEC 61850-based 154kV Main transformer bay IED solutions to these two project.

High-speed rail study needs to focus on passenger movements as a key element of the planning process. A particular challenge is obtaining comprehensive information on high-speed rail passenger movements. A national preference stated survey was conducted from October to November of 2011 to meet this challenge through direct personal interviews of travelers between Seoul and Busan (the so called Kyung-Bu corridor). Over 40 interviewers were hired and trained to conduct personal interviews at several stations along locations within Kyung-Bu Seoul and Busan corridor. A total of 4,550 travelers were interviewed, furnishing an extensive database on high-speed rail passenger movements. The methodology and procedure employed to collect the national data for Korean high-speed train KTX are described. Specific issues investigated include survey design, questionnaire and strategy. Lessons learned from the high-speed rail passenger movement study provide insights for other countries contemplating similar high-speed rail studies.

The Korea Institute of Nuclear Safety, as a representative organization of Korea, in February 2012 participated in an international Program to Assess the Reliability of Emerging Nondestructive Techniques initiated by the U.S. Nuclear Regulatory Commission. The goal of the Program to Assess the Reliability of Emerging Nondestructive Techniques is to investigate the performance of emerging and prospective novel nondestructive techniques to find flaws in nickel-alloy welds and base materials. In this article, Korean round-robin test results were evaluated with respect to the test blocks and various nondestructive examination techniques. The test blocks were prepared to simulate large-bore dissimilar metal welds, small-bore dissimilar metal welds, and bottom-mounted instrumentation penetration welds in nuclear power plants. Also, lessons learned from the Korean round-robin test were summarized and discussed.

This paper discussed the application process of the Dot Idea program. The Dot Idea program is an incubation and open innovation program co-created by Unitec, an incubator at Tecnosinos Tech Park, and an SAP innovation team. The main objective of this study was to cover an existing gap in the literature regarding the practical application of an open innovation methodology. Many companies seek interaction with external parties to enable advancement toward identified innovation opportunities. Technology clusters, parks, and incubators have played an important role in promoting connections and interaction. Consequently, the Dot Idea program emerged as a result of a joint effort to create a program using a design science research methodology aiming to foster new businesses and strengthen Brazil and Latin America as a hub to develop new solutions for traditional organizations. In regards to lessons learned, the Dot.health trial had some success but also experienced difficulties; these related to the relationships between startups and a hospital's internal teams, and startups' needs to be funded from the beginning in order to be fully dedicated to a project.
