By employing the subscriber concept in broadcasting services, IPTV (Internet Protocol Television) operators provide various grades of services to subscribers based on the billing level of the subscribers. With the income from subscribers for a basis, IPTV operators plan to provide high quality services. Since Web browser-based IPTV provides T-commerce and E-commerce services as well as television services, users may frequently visit other service domains to buy goods or content. To provide the user with charged or private services, these service domains request authentication of user. The existing authentication system is not appropriate for the IPTV service environment because the environment unavoidably forces the user to cross from one authentication-based service domain to another. Single sign-on provides a user with transparent authentication services by enabling an authenticated user to move between authentication-based service domains without any re-authentication. Like this distributed environment, since the IPTV service environment also provides a variety of authentication-based services, transparent authentication service needs to be provided to subscribers who want to access charged or private services. In this paper, we propose a new user authentication scheme for the IPTV environment. This scheme integrates the Security Assertion Markup Language (SAML), which is a standard for XML-based single sign on. We validate this scheme using a simple use case scenario.

A phenomenon in the unplanned urban sprawl of Cheong-ju city has to be rest-rained from disposing and to develop, though progress in urbanization inevitably decreases rural area. So, this thesis aims at reviewing, revising and guiding toward the more effective land use planning practice and zoning mechanism and system of Cheong-ju city. I proposed that land use planning should be had several factors and thereupon that Korean zoning mechanism and system including Building Code should be amended because of inducing human activities in buildings and facilities not to demarcate and plan every one of them. First, the factors of urban planning are a rather diversified approach to it than a unified, supplementation of the applicable difference in time between preparing and appling it, a solid controlling system, a micro and macro planning theory and giving serious consideration for the inertia from the existing land use. Second, the applicable amendments for our zoning mechanism including Eluding Code are as follows; a need of reorganization for Zoning Ordinance appricated to different regulation concerning a scale and peculiarity of a oily, a decision of the different earmarked confinement in area to different zone ana from Zoning Ordinance in City Planning Law, a demarcated facilities and the more detailed land use concerning human activies than the exsisting and entrusting decision on the ways and processes of it to every rural city planning committee, a settlement of zone ana area considering for block-unit and Planned Unit Development(P. U. D.), and a need of security jurisprudence in order to solve the zoning regulation rather in City Planning Law than in Building Code that our zoning regulation and controlling system are depended on. According to these applicable amendments to Cheong-ju city, I proposed the conceptions of Cheong-ju city land use planning are as follows; a reinforcement with one cored pattern of urban land use, a selection of gradual urban sprawl by way of city development and renewal, a strengthening accessibility to the core of the city with Plurizing the system of arterial roads, a choice of priority to conservation at the core of tile city and security of open spaces and parking area at the area of the city, a harmonization between development and conservation at the inner ring area that is situated between the core and periphery reserved area in order to develop in the future, a buffered open space situated at the congested area with heterogenous functions, and a completion of urban open space system. The proposal made here so far is for the hope of the better structure of Cheong-ju city that should be granted to the peculiarity developed with educational, cultural, conservative and self-sufficient city functions.

This study is to provide the implementation plan for standard code to efficiently manage curriculum information in disaster and safety education programs across domestic and foreign institutions, and to encourage active information sharing. Projects regarding disaster safety education have been progressed and developed since the opening of NDMI on March 2006. Efficient management and systematic operation for the existing disaster safety education contents are also required. It is essential for both domestic and foreign disaster management organizations to share and utilize their educational contents each other prior to the effect of the Framework Act on the Management of Disaster and Safety starting from February 7th, 2014. As disaster gets more complex and diverse in its types and sizes, the share of information on advanced disaster and safety education system between each countries is becoming more necessary than they ever did before. Therefore, the standard code of disaster safety education curriculum is resulted based on the flexibility that accommodates the change of education environment and extended applications in both domestic and foreign education institutions. The effective application of standard code will be a possible way to improve the disaster safety education system and help to set its correct definition.

The military purpose vehicles are developed by using the platform of civil vehicles according to the commercial vehicle expansion plan and military supplied product commercialization policy. But the information related to the military purpose vehicle which adopts the same platform with the civil vehicle is forced to be exposed because its information is revealed by containing into the maintenance manual and electric circuit diagram. Especially, the information disclosure should be blocked by reviewing the application of technology protection because the military vehicle becomes combating purposed mixed equipment when the missile and radar are mounted. The mixed equipment means the one configured with more than 2 types of equipment, and it is categorized into the main and sub equipment. This study was performed to derive the problems in Korean system for vehicle part test evaluation on the mixed equipment and the defense industry technology protection system, and to derive the methods for improving through interviews with the specialists. The conflicts between the civil laws and army regulation were reduced by adding a clause that the engine reflected with the newest emission gas standard should be mounted based on the time of force integration, and the commercialized military supplies were designated as element technology of defense industry technology in consideration of its roles and functions.

M&As are continuing to grow globally and are expected to increase in the future. With the fourth industrial revolution and the strengthening of neo-protection trade between countries, technology is cited as the core of national competitiveness, and the trend of M&A's increase, which is aimed at securing technology, is expected to continue. However, the risk of technology leakage, which is difficult to determine clearly illegally in the process of M&A, is still growing, and there is not enough prevention or response to this problem. the purpose of this paper was to divide the M&A process into seven stages and to ensure that important information of the enterprises during M&A between the countries and the domestic companies was not leaked unfairly, and each step analyzed the risk factors and causes of the leakage of important information in the M&A process and presented a risk-specific management plan for minimizing the leakage of important information based on the importance of the risk factors. Companies that pursue M&A in the future will reflect the M&A step-by-step risk and risk management measures derived based on case analysis and expert surveys. I hope to use risk management measures to help minimize unintentional leakage of important corporate information into the outside.

In this study, the two-dimensional flow analysis model Hydro_AS-2D model was used to simulate the situation of flooding in Seongsangu and Uichang-gu in Changwon in the event of rising sea levels and extreme flooding, and the results were expressed on three-dimensional topography and the optimal evacuation path was derived using BIM technology. Climate change significantly affects two factors in terms of flood damage: rising sea levels and increasing extreme rainfall ideas. The rise in sea level itself can not only have the effect of flooding coastal areas and causing flooding, but it also raises the base flood level of the stream, causing the rise of the flood level throughout the stream. In this study, the rise of sea level by climate change, the rise of sea level by storm tidal wave by typhoon, and the extreme rainfall by typhoon were set as simulated conditions. The three-dimensional spatial information of the entire basin was constructed using the information of topographical space in Changwon and the information of the river crossing in the basic plan for river refurbishment. Using BIM technology, the target area was constructed as a three-dimensional urban information model that had information such as the building's height and location of the shelter on top of the three-dimensional topographical information, and the results of the numerical model were expressed on this model and used for analysis for evacuation planning. In the event of flooding, the escape route is determined by an algorithm that sets the path to the shelter according to changes in the inundation range over time, and the set path is expressed on intuitive three-dimensional spatial information and provided to the user.

The importance of citizen as a key of community safety has increased, and the legislation to support the citizen's activities is continued. However systematic and detailed action plans are not enough to something. Thus, the purpose of this research is to develop the educational program model for the citizens on patrol for the improvement of practical use. The methods of this research are to make and suggest the educational program for citizens on patrol by literature review and cases analysis of educational program implemented one years ago. The findings are suggested as belows. First, the learners need the contents can be practically used in the field and sufficient time of education. Second, the subgoal to achieve the ultimate goal of education program model should be established as 'customer-centered, field-oriented, competence reinforcement', and driving strategy must be composed of four stages as plan-design-implementation-evaluation. Also, for strategy of each stage, detailed sub-strategies from preparation to execution of education have to be considered. Third, education program must be categorized by basic-intermediate-expert courses depending on the level of learners, and theoretically and practically oriented curriculum subjects are organized in balance by each course.

Recently the Ministry of Health and Welfare, Republic of Korea, announced the “Dietary Guidelines for Korean Adults (DGKA)”, which includes ten Dietary Goals, six Dietary Guidelines, and twenty-three Action Guidelines. DGKA are developed as the revision of the 2003 Dietary Guidelines for Koreans, targeting adult population. Dietary Guidelines are developed for general purpose as well as for different age groups. They are revised periodically to accommodate changes in diet and health problems of the population. The process of developing new DGKA can be summarized as 1) selection of focus areas, 2) analysis and review of available data for each area selected, and 3) derivation of guidelines based on the analyzed data, and 4) finalizing the guidelines after open discussions among the experts and general public. Five focus areas were selected by examining the Nutrition Goals of the Health Plan 2010 of Korea, soliciting proposals from the experts in the related fields, and reviewing existing and international guidelines. Five areas selected were 1) adequate intake of nutrients and foods, 2) balance of energy intake and physical activities, 3) alcohol intake, 4) food security and nutrition service, and 5) food safety. Adequacy of nutrient and food intakes of the Korean adult population was assessed using 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Newly developed Dietary Reference Intakes for Koreans were used as reference values to assess the prevalence of inadequacies and excesses in nutrient intakes. Energy balance was examined with energy intake of 2005 KNHANES survey and results of physical activity questionnaire in the survey. Alcohol intake was also examined using 2005 KNHANES results of dietary intakes as well as the results of questionnaire survey on alcohol intakes. Food security, nutrition services, and food safety were analyzed using various government data and published results on the issues. Ten Dietary Goals and six Dietary Guidelines were developed after data analysis and were subjected to reviews of experts and general public. The final DGKA are: 1) Eat a variety of foods from each food group, 2) Increase physical activity and maintain healthy weight, 3) Eat proper amount of clean foods, 4) Avoid salty foods and try to eat foods with bland taste, 5) Avoid foods with high fat contents and deep-fried foods, and 6) When you drink alcohol, limit the amount. Twenty-three action guidelines are developed in order to achieve these guidelines in actual diet and life among the population. The government is disseminating the guidelines with “337” slogan and emblem. “337” indicates everyone should practice “3” guidelines of promoting good eating practice, “3” guidelines to limit or decrease in your diet, and you should practice them for “7” days a week. The guidelines will be useful in promoting healthy food habits and good nutritional status which will result in decrease nutrition related health problems in Korea.

Despite the global promotion of Smart City, there is currently no standard for smart water grid development, and it is not possible to judge the success of Smart City. There is a clear need to establish the requirements and goals of the Smart Water Grid and accurately diagnose and improve the limitations and problems of the existing Smart Water Grid. For this purpose, it is very important to use the index suitable for Smart Water Grid goals. In this study, we developed Smart Water Grid Index which can be used to evaluate the target measurement and attainment of Smart Water Grid and can be utilized based on the implementation plan for Smart Water Grid in the future. Through the development of the Smart Water Grid Key Performance Index (SWG KPI), we will lay the groundwork for continuous capacity evaluation of the Smart Water Grid and improve the reliability of the Index. It is expected that it will be possible to prepare and evaluate a Challenge Evaluation Card for the planned Smart Water Grid by providing an evaluation table for grid competency evaluation.
