City's inhabitants should be able to utilize a variety of urban infrastructures and public facilities in a way of possessing the convenience, amenity, and safety of urban life. Most of the city government, however has established a policy for making and providing urban park facilities based on a very simple quantitative criteria rather than the qualitative criteria such as appropriateness, utility, accessibility, equity so far. Especially in the case of urban neighborhood parks, the usefulness to the inhabitant and accessibility to the parks may be questionable. In this study, we intended to analyze the spatial equity and distribution characteristics of urban neighborhood parks and to select several potential facility sites required in the study area using GIS's spatial analysis functions. Finally this study analyzes the possible location of an urban neighborhood park in terms of objective criteria and AHP techniques.

This study concerns the design strategy for the waterside of Gyeong-In Ara Waterway, Korea’s first constructed canal. This design focused on the creation of a new paradigm for waterway landscapes the major factors of which were geographical advantage, value of landscape and efficient approach. As the major space plan for the waterfront formed through the Gyeong-In Ara waterway from the Yellow Sea to the Han River, eight good views of the waterfront zone were designed by utilizing the waterway as a scenery viewpoint and, by constructing two traffic lanes for the scenic parkway connecting Incheon and the Gimpo terminal, both a linear greenway as well as various waterfront facilities were also designed. A boardwalk and bike path connecting the major theme parks were planned, and a waterfront pocket park was then organized based on the bike path. In this study, the result of the new waterfront result from the Gyeong-In Ara waterway was planned to have an identity as a new waterside culture space in order to achieve multiple functions including environmental, cultural, leisure, and tourism as well as management programs based on a variety of applied culture content and story-telling.

Construction of multi-site Cloud Infrastructure with OpenStack, the most popular cloud open source project with various ICT infrastructure technologies, has operational inefficiency due to installation complexity and geographical limitation. To address this inefficiency, we gradually developed automated installation/configuration tools to automate installation/configuration of Linux and OpenStack by complying with DevOps methodology over a multi-site OpenStack testbed called OF@KOREN SmartX Playground. However, the pre-developed installation tools can be used only for limited cases. Therefore, we designed and developed a prototype of SmartX Provisioning Framework which could conducts Playground-wide provisioning flexibly by following three steps of resource management in Software-defined Infrastructure. We verified the efficiency of the provisioning functionality of the framework by demonstrating an example of automated multi-site cloud construction.

The goal of this research is to develop the method of facility management which is used to manage the facility efficiently by using existing analyses of a system and a operation, and establish the method of a facility administration by applying AHP(Analytic Hierarchy Process) model. Because the standard of a accuracy in spacial analysis and calculation is a unclear, the exact analysis of a geographic data for a decision-making needs statistical analysis and administrator-centered type of system didn't satisfy the desire of users. There must be the existing general statistics module, integrated internet GIS and the composition of interface in order to structure a spacial statistics analysis methods that satisfy the matters desired in internet GIS into the spacial analysis function. This paper presents the need of internet GIS and AHP Model in supporting and managing function of all facilities in campus and introduce the possibility of applying.

The main research question of this paper is as follows: How can broadcasting both cause the crisis in democratic participation and yet also offer the solution? The contradiction in broadcast localism has never been adequately resolved in spite of regulation at all in practice, in that localism simply cannot account for the diversity of modern life and for the external forces that incorporate local communities into much larger economic and communications network. The concept of locality in local television, however, has been multiplied and enlarged in order to adjust to "time-space compression". Recently the local television have been "interface" combining and negotiating the globalization of media market and the decentralization of political power, the economies of scale and the activation of local democracy, consequently aiming at the horizontal-cooperative network instead of old vertical-dependent one.

It is often challenging to evaluate local spatial association among onedimensional vectors generally representing paired-location events where two points are physically or functionally connected. This is largely because of complex process of such geographic phenomena itself and partially representational complexity. This paper addresses an alternative way to identify spatially autocorrelated paired-location events (or vectors) at a local scale. In doing so, we propose a statistical algorithm combining univariate point pattern analysis for evaluating local clustering of origin-points and similarity measure of corresponding vectors. For practical use of the suggested method, we present an empirical application using transactions data in a local housing market, particularly recorded from 2004 to 2006 in Franklin County, Ohio in the United States. As a result, several locally characterized similar transactions are identified among a set of vectors showing various local moves associated with communities defined.

Recently, the use of digital audio and video as proof in criminal and all kinds of litigation is increasing, and scientific investigation using digital forensic technique is developing. With the development of computing and file editing technologies, anyone can simply manipulate video files, and the number of cases of manipulating digital data is increasing. As a result, the integrity of the evidence and the reliability of the evidence Is required. In this paper, we propose a technique for extracting the Electrical Network Frequency (ENF) through a grid of power grids according to the geographical environment for power supply, and then performing signal processing for peak detection using QIFFT. Through the detection algorithm using the standard deviation, it was confirmed that the video file was falsified with 73% accuracy and the forgery point was found.

The contents of geographical education present too inclusive and abstract regard as criteria in an existing curriculum. And geographical education oneself's system is difficult because they are set to the one part of educational side. This study pursuit to make content standard of geographical education based on geography as an alternative. This paper present standard setting up 5 steps. They are Ultimate Theme, Basic Theme, Major Standard, Standard, Detailed Standard. Ultimate Theme is discern geographical education whole : understand of interaction human and environment, understand of place and region, understand of interaction human and region. Basic Theme is concrete of ultimate theme ; geographical skill, physical environment, human environment, place and region, interaction of human and region. Standard is concrete and measurable level of basic theme, it is consist of three steps in Major Standard, Standard, Detailed Standard tv level of specification. Major Standard is consist of 17 item, Standard is 48 item, and Detailed Standard is detailed to unit level.
