  • In this paper, we present a method for effectively predicting traffic volume based on vehicle location data that are collected by using LDP (Local Differential Privacy). The proposed solution in this paper consists of two phases: the process of collecting vehicle location data in a privacy-presering manner and the process of predicting traffic volume using the collected location data. In the first phase, the vehicle's location data is collected by using LDP to prevent privacy issues that may arise during the data collection process. LDP adds random noise to the original data when collecting data to prevent the data owner's sensitive information from being exposed to the outside. This allows the collection of vehicle location data, while preserving the driver's privacy. In the second phase, the traffic volume is predicted by applying deep learning techniques to the data collected in the first stage. Experimental results with real data sets demonstrate that the method proposed in this paper can effectively predict the traffic volume using the location data that are collected in a privacy-preserving manner.

  • This study presents how to vitalize the record management of the provinces by investigating the current issues and by identifying the universality and the distinctiveness of the record management in local agencies. However, it only deals with the system of the record management, focusing on the history of the provinces. Although the related projects conducted by the provinces of Korea consist of various types, including publishing the local history, creating the activities of local cultural institutes, and collecting and organizing the historical records, these have not been active in many regions with insignificant achievements. In this regard, local self-governing bodies need to actively fulfill the duty of the management not only for the administrative archives but also for the historical archives by aggressively interpreting the associated parts suggested by the Act on the Management of Public Archives. Ultimately, it is proper to integrate theses two functions. Moreover, an effective collection is the core part of the record management of history. Therefore, a 'committee' with experts should provide in-depth views from planning to post-processing stages. Meanwhile, a consensus on the importance and the necessity of the historical archive management between owners and concerned parties should be formed during the collection process. In conclusion, each local autonomous entity should make sure of the active record management of history through establishing their own mid to long-term development plans, securing experts in archive management, as well as providing the service for record contents.

  • Although the native local data is being deemed important in the age where historical records are regarded as important, currently it is hard to find out detailed actual state of local data, because it is now being collected and managed by many institutions and individuals. This study is aimed at surveying the current state of management of native local data possessed by local cultural center, one of institutions that produce and manage local data, and suggesting a desired alternative idea of cultural center for management of native local data, through the problems found by the research. As the result, the current state of data management of the local cultural center are as follows: First, local data management in the local cultural center as the problem in poor surroundings and a financial question get local data-related education make systematic data collection and management unavailable. Second, local data depends on the extent of its awareness of it. each and every cultural center shows a significant deviation in the extent of execution of local data-related project. Third, even though the publication business of the cultural center is being lively executed, it attaches importance to the history of local authority rather than to the residents' life, and it should not be supplemented in applying it to education and production of cultural contents.

  • This study is to analyze the Korean translation of "Goseong Chongswaerok" by O Hoeng-muk as a local governor through political ecology. It focuses on how O Hoeng-muk recognized and wrote the interrelation among weather, agriculture, local resident's life, and local policy. The results are summarized in the followings. Firstly, weather was recorded into three types of expression, simple and dynamic expression and agriculture-related expression. Its dynamics was much meaningful and important when weather was related to local resident's life and local or non-local economy and politics. Secondly, weather and local government were conflict under a particular natural condition like severe drought. And society and politics are affected by such a conflict. Thirdly, local people's demonstration was occurred under a certain condition. Bounded agency can be founded in O Hoeng-muk's behavior as a local governor like jinhyul(賑恤), rain rituals, tax collection. Fourthly, the interrelation among weather, agriculture, local people's life, and local policy implemented in a particular local like Goseong ought to be interpreted in terms of multiple scales.

  • Recently, environmental issues have become serious, and Jeju Island is promoting a pilot project of a smart collection system(waste weight-based collection system) at clean houses in Yongdam 1-dong. However, the new system faced an opposition from elderly residents who were not accustomed to using machines or smart devices. In order to solve this problem, it was intended to suggest policies related to this by conducting environmental education and identifying problems with the effect of environmental education awareness through data analysis method. The results showed positive answers in most of the satisfaction and achievement evaluations, but it is also true that most of the residents need to be educated and more information should be given. In order to vitalize education, it is important to increase the number of instructors and support them to increase their expertise. It is also important to take a practical process that strengthens public relations, shares information, and links with the local community to increase the actual participation of local residents. In addition, it is critical to secure a budget from local governments to maintain education and public awareness, and it will be helpful to link with talent donation projects in the region.

  • Cowpea might have been introduced from China to Korea and cultivated for several hundred years but it has never been a staple food crop in Korea. In this study, genetic diversity of 492 Korean cowpea landrace accessions that have passport information was estimated using six SSR markers. The mean of Weir's gene diversity was 0.665 from all accessions investigated in the study. Cowpea gene diversity of six local provinces in Korea was ranged from 0.370 in accessions of Gangwon to 0.680 in Jeonra provinces. Low gene diversity of the cowpea genepool of Gangwon province was probably derived from relatively few introductions. Especially SSR markers VM36 and VM39 seem to be good markers to distinguish the Gangwon accessions from others by occurring at a specific locus with higher than 78% of allele frequency. Except for the Gangwon province with the low genetic diversity, gene diversity of cowpea accessions from other provinces was ranged from 0.600 to 0.680 indicating no big differences among provinces. Distribution pattern of the allele frequencies was similar among the other provinces. This may reveal that Korean farmers might exchange cowpea seeds easily with even their neighbors with geographical barriers. A core collection, 100 landraces, ca. 20% of base collection, was developed at the 70% of a similarity coefficient level using random sampling approaches after stratification of the entire landrace collection based on the phenetic dendrogram. The variability of SSR in the base and core collections of Korean cowpea landrace was compared by calculating Weir's gene diversity. The mean of Weir's gene diversity of the core was 0.707 while that of the base collection was 0.665. The higher diversity index in the core collection indicates that it maintains the initial variability and well represents the base collection. The core collection included one of determinate accession (IT 216155) and two of no branching type accessions (IT 103959 and IT 161024). The core collection could be used to guide more efficient management and utilization of the entire collection. This core collection should be revised periodically as additional accessions are collected and further characterization is conducted.

  • A distributed video-on-demand (VoD) system is one where collection of video data is located at dispersed sites across a computer network. In a single site environment, a local video server retrieves video data from its local storage device. However, in the setting of a distributed VoD system, when a customer requests a movie from the local server, the server may need to interact with other servers located across the network. In this paper, we present three types of presentation plans that a local server must construct in order to satisfy the customer request. Informally speaking, a presentation plan is a temporally synchronized detailed sequence of steps that the local server must perform for presenting the requested movie to the customer. This involves obtaining commitments from other video servers, obtaining commitments from the network service provider, as well as making commitments of local resources, within the limitations of available bandwidth, available buffer, and customer data consumption rates. Furthermore, for evaluating the goodness of a presentation plan, we introduce two measures of optimality for presentation plans: minimizing wait time for a customer, and minimizing access bandwidth is used. We develop algorithms to compute optimal presentation plans for all three types, and carry out extensive experiments to compare their performance. We have also mathematically proved certain results for the presentation plans that had previously been verified experimentally in the literature.

  • This paper proposes a gradation image processing method for the development of a Road Sign Recognition Platform (RReP), which aims to facilitate the rapid and accurate management and surveying of approximately 160,000 road signs installed along the highways, national roadways, and local roads in the cities, districts (gun), and provinces (do) of Korea. RReP is based on GPS(Global Positioning System), IMU(Inertial Measurement Unit), INS(Inertial Navigation System), DMI(Distance Measurement Instrument), and lasers, and uses an imagery information collection/classification module to allow the automatic recognition of signs, the collection of shapes, pole locations, and sign-type data, and the creation of road sign registers, by extracting basic data related to the shape and sign content, and automated database design. Image division and merging, which were applied in this study, produce superior results compared with local binarization method in terms of speed. At the results, larger texts area were found in images, the accuracy of text recognition was improved when images had been gradated. Multi-threshold values of natural scene images are used to improve the extraction rate of texts and figures based on pattern recognition.
