In Korea, local governments have decided the location of shelters as part of their disaster planning. However, no quantitative standards, such as assuming different hazard and shelter types, shelters' capacity, are specified in that planning. To propose the direction of disaster evacuation policy, first of all, the current state of shelters' location and evacuation area is needed to be analyzed. In addition, considering topographical condition such as road slope and physical strength by age are important factors to measure optimal evacuation route. The purpose is to suggest a new methodology of estimating optimal evacuation route considering resistance of road slope and difference of walking speed by age. Moreover, as a case study of Seoul, Korea, using coverage analysis of GIS analysis tool, the accessible area (or vulnerable area) to the shelters is evaluated based on the spatial distribution of disaster evacuation shelters and their accommodation capacity, according to evacuation time within 7.5, 15 and 30 minutes. The main results are summarized as follows: 1) The average area of disaster evacuation shelter per person is calculated as 0.45 square meters. Considering that the minimum shelters' area per person is 1 square meters, only 45% of people in Seoul can be accommodated. 2) The ratio of inhabitants who live in accessible area within 7.5 minutes presents only 33% of all. Furthermore, the ratio of inhabitants by age group of 5~9 or over 65 years old shows significantly lower percentage in comparison with 15~49 years old people.

this study, an expert AHP questionnaire analysis of public and private groups was conducted to take into consideration the requirements for realistic disaster services. Considered are public areas that manage disasters like fires and earthquakes that can be a major threat to national safety, as well as private areas that mainly develop disaster-related technologies. In the questionnaire, the public respondents valued accurate disaster situation information (ranked 4th and 6th) for citizens (1st), managers (3rd), and related organizations (2nd); the private sector highly valued the importance of three-dimensional (3D) control (ranked 1st, 3rd, and 5th) using future technologies. This study suggests the realization of a disaster-response service that meets the needs of public safety and technological innovation based on a 3D safety state information platform. We anticipate that this study will provide useful data for applying technology and for establishing detailed scenarios during the test bed and commercialization phases. We also expect that further studies will be conducted, such as the practical application and operation of realistic disaster response services, on the financial resources for the proliferation of local governments, and on policy support measures.

Film-induced tourism in Gyeongbuk and Korea is concentrated on the on-location set, one-off events and film tourism as part of a holiday(visiting film locations or studios as an activity within a larger holiday) among several forms of film-induced tourism. Film-induced tourism in Gyeongbuk has been increased since the opening of the KBS on-location set of Mungyeong. The on-location set has brought the growth of film-induced tourism and thus many local governments have competed with one another for the construction of the on-location set without considering the management of the on-location set. This study is aimed at suggesting ways to minimize these negative problems and to boost film-induced tourism. First of all, we should find ways to sustain each characteristic of the on-location set. Second, we should develop the new tourism destinations by diversifying the forms of film-induced tourism through the opening of the film-related events and the construction of the film-related facilities. Last, film-induced tourism should be enlarged to contents tourism. It needs to enlarge the role of the Gyeongbuk Film Commission. The Gyeongbuk Film Commission should take exclusive responsibility of developing the film-related tourism commodities.

Recently many countries around the world are actively promoting smart city projects to address various urban problems such as traffic congestion, housing shortage, and energy scarcity. Due to development of the Internet of Things (IoT), the development of a smart city with sustainability, convenience, and environment-friendliness was enabled through the effective control and reuse of urban resources. The purpose of this study is to analyze the technical trends of IoT and present a development plan for smart city which is one of the applications of the IoT. To this end, the news articles of the Electronic Times between 2013 and 2015were analyzed using the text mining technique and smart city development cases of other countries were investigated. The analysis results revealed the close relationships of big data, cloud, platforms, and sensors with smart city. For the successful development of a smart city, first, all the interested parties in the city must work together to create new values throughout the entire process of value chain. Second, they must utilize big data and disclose public data more actively than they are doing now. This study has made academic contribution in that it has presented a big data analysis method and stimulated follow-up studies. For the practical contribution, the results of this study provided useful data for the policy making of local governments and administrative agencies for smart city development. This study may have limitations in the incorporation of the total trends because only the news articles of the Electronic Times were selected to analyze the technical trends of the IoT.

The purpose of this study is to present the directivity of outcome management through the analysis of public library operations in Seoul. For this purpose, author evaluated the public library policies by linking the 「Metropolitan Comprehensive Library Advancement Plan 2018~2022」 and 「The Third Comprehensive Library Advancement Plan: 2020 implementation plan」 and compiled to draw up the issue of policy development on the awareness of public library services by Seoul citizens. Nest, author analyzed and compared the core infrastructure, collection services, programs and activities of 173 public libraries in 25 local governments. Based on these results, author suggested the directivity of outcome management as follow. All public libraries in Seoul must emphasize the development scope and management methods of the performance indicators. For outcome management, this study emphasized building a strategy planning with the development procedures of performance indicators, categorizing outcome management indicators, developing user-centered indicators, and improving qualitative indicators. As there is a possibility that the quality of services expressed in the output may deteriorate due to the failure of the physical input indicators, it is necessary to strengthen the input and encourage the resolution of the service gap by establishing a performance management system to logically explain the relevance or causal relationship between these indicators.

Three-dimensional geo-spatial information is important for the efficient use and management of the country and the three-dimensional expression and analysis of urban projects, such as urban plans devised by local governments and urban management. Thanks to the revitalization of the geo-spatial information service industry, it is now being variously used not only in public but also private areas. For the creation of high-guiltily three-dimensional geo-spatial information, emphasis should be placed on not only the quality of the source image and three-dimensional geo-spatial model but also the level of visualization, such as level of detail and texturing. However, in the case of existing three-dimensional geo-spatial information, its establishment process is complicated and its data are not updated frequently enough, as it uses ready-created digital maps. In addition, as it uses Ortho Images, the images exist Relief displacement. As a result, the visibility is low and the three-dimensional models of artificial features are simplified to reach LoD between 2 and 3, making the images look less realistic. Therefore, this paper, analyzed the quality of three-dimensional geo-spatial information created using the three-dimensional modeling technique were applied using Digital photogrammetry technique, using digital aerial photo images by an existing large-format digital camera and multi-looking camera. The analysis of the accuracy of visualization information of three-dimensional models showed that the source image alone, without other visualization information, secured the accuracy of 84% or more and that the establishment of three-dimensional spatial information carried out simultaneously with filming made it easier to gain the latest data. The analysis of the location accuracy of true Ortho images used in the work process showed that the location accuracy was better than the allowable horizontal position accuracy of 1:1,000 digital maps.

The fire damage has been increased as the frequency of fire incidence decreases with increasing in death and economic loss. Local governments are dependent on the activities of fire-fighters with crude preparedness and prevention for fire incidence. Most of researches on fire safety have focused on descriptive statistics which show general trends in fire incidence and condition. Here we tried to make a mutual causal model for fire damage, to make three big hypotheses with laying three small hypotheses under each big hypothesis. Five years statistics from public domains in the form of hardcopy or softcopy were collected and fifteen independent variables were selected to explain the number of death, the number of fire incidence and the amount of economic loss from fire incidence. The significances of statistics are different among the regional characteristics. The hypotheses were partially rejected and the meanings of rejected factors will refresh the tentative prejudice. It is necessary to revise the principle that the number of population and size of area are regarded as the most important criteria to allocate resources for fire control and to have the criteria flexible with results of our research such as the number of the weak to fire disaster.

A traditional garden in Korea has diverse cultural, historical values, such as the then phases of the times, life phase, culture and art, etc. because it was developed on the basis of the harmony between nature and artificial structures. However, in reality, it's urgent to do efficient, continuous maintenance of traditional gardens which are being damaged and lost due to the problems like an owner's aging, inheritance, and lack of management, etc., especially in case of private property which was designated as a cultural property among such traditional gardens under the Cultural Properties Protection Law. Accordingly, this study conducted this research in a bid to use these research results as basic evidentiary materials for suggesting directivity in introduction of park planning of traditional gardens in folk houses in the near future by implementing the case investigation of transformation into public parks from traditional private gardens in Japan, which is putting the newly introduced park planning to efficient use, together with its systematic management, and the survey on domestic traditional gardens in folk houses status, as well as the hearing-based survey on a traditional gardens in folk houses owner's level of willingness to accept the introduction of parking planning. As a result, this study could confirm that in case of traditional gardens in Japan, they are mobilizing the revenue from admission fees for traditional gardens maintenance by incorporating the main entity of possession, and Japan is promoting transformation of traditional gardens into parks on the basis of use and preservation through the connection with local governments and research institutes. In addition, as a result of surveying domestic traditional gardens in folk houses, it was found that most of the garden owners had hardships in its management, and they were positive about systematic maintenance of gardens through park planning.

Government introduces a Total Maximum Daily Loads(TMDL) which can be implemented for total pollutant amounts in 2004. Normally, the local governments have been calculated the amounts of pollutant discharge of each watershed using a water quality model. However, among the input data to use the water quality model, creating a schematic diagram of the stream or the modeling usually requires considerable amount of time and efforts due to the manual work. Therefore, this study tried to develop an algorithm which automates the creation of a schematic diagram for water quality modeling using the Korean Reach File capable of river network analysis. Further, this study creates a schematic diagram with the shape of a stream utilizing GIS capabilities. The diagram can be easily analyzed with overlapping various spatial information such as pollution sources and discharge points. This study mainly has automated element segmentation algorithm to divide streamflows into equal distance using line graphic data of Koran Reach File. Also, automated attribute input algorithm has also been developed to enable to insert element order and type into elements using point graphic data of Korean Reach File. For the verification of the developed algorithm, the algorithm was applied to kyungan stream basin to see the acceptable results. To conclude, it was possible to automate generating of schematic diagram of water quality model and it is expected to be able to save time and cost required for the water modeling. In future study, it is necessary to develop an automatic creation system of various types of input data for water quality modeling and this will lead to relatively easier and simple water quality modeling.
