Even on the point that the 3rd National GIS project is being executed following the completion of the 1st and 2nd, the National GIS utilization is still very low. It is well reasonable to anticipate that the utilization will grow much higher, as the national spatial data infrastructure had been almost equipped through the 1st and 2nd project periods. Facing the ubiquitous era, in particular, as the national-level GIS demand is to increase to a great extent, pre-established GIS application scope will become much wider, too. In preparation for these, the current study focused on the National GIS utilization system by reviewing on the execution procedures to evaluate the outcomes. For the actual administration procedures, to note, the National GIS utilization statuses by local municipalities were investigated in depth. And the barriers for the National GIS utilization enhancement were analyzed to look for feasible solutions. The results suggested were aimed to contribute to the amendment of the 3rd Master Plan, and to be used as part of the basic data for the establishment of the 4th Master Plan for the National GIS.

Most research materials (data), which are used for the study of digital mapping and digital elevation model (DEM) in the field of Remote Sensing and Aerial Photogrammetry are aerial photographs and satellite images. Additionally, they are also used for National land mapping, National land management, environment management, military purposes, resource exploration and Earth surface analysis etc. Although aerial photographs have high resolution, the data, which they contain, are not used for environment exploration that requires continuous observation because of problems caused by its coastline, as well as single - spectral and long-term periodic image. In addition to this, they are difficult to interpret precisely because Satellite Images are influenced by atmospheric phenomena at the time of photographing, and have by far much lower resolution than existing aerial photographs, while they have a great practical usability because they are mulitispectral images. The PKNU 2 is an aerial photographing system that is made to compensate with the weak points of existing aerial photograph and satellite images. It is able to take pictures of very high resolution using a color digital camera with 6 million pixels and a color infrared camera, and can take perpendicular photographs because PKNU 2 system has equipment that makes the cameras stay level. Moreover, it is very cheap to take pictures by using super light aircraft as a platform. It has much higher resolution than exiting aerial photographs and satellite images because it flies at a low altitude about 800m. The PKNU 2 can obtain multispectral images of visible to near infrared band so that it is good to manage environment and to make a classified diagram of vegetation.

The purpose of this study is to estimate the appropriate Demand Responsive Transport (DRT) fare for bus users upon introduction of the system, which is to improve ridership on economically non-profitable routes and to conform to the mobility right of those living in presently non-serviced rural areas. For this, a stated preference (SP) survey was adopted to assess respondents' preferences regarding DRT introduction, while the contingent valuation method (CVM) was used to calculate their willingness to pay (WTP) for DRT services. The analysis results show that, compared to the existing bus services with a 1,000 won bus fare, the value of DRT is considered to be 38.85%, 31.03% and 30.12% higher in terms of overall assessment, usability and convenience, respectively. The results of this study are expected to facilitate the decision making aimed at setting the appropriate DRT fare and implementing a DRT system that meets sustainability requirements.

Silica-based inorganic fillers for restoration of iron objects have been used for the reduction of thermal expansivity and the improvement of melt flow index. However, the higher the amount of filler is applied, the more degradation of mechanical properties and the yellowing occur, which could cause retreatment of the objects with adding stress to them. Thus, research on not only the quantification of a mixture of resin and filler but also the yellowing should be emphasized. Experiments on mechanical properties were carried out with a silica-based light filler, Micro Shell as a comparison group. The results of the experiment showed Micro Shell reduced the number of occurrences of the yellowing by 34% compared to existing fillers. The value of adhesion and specific gravity was also improved depending on the filler amount. The results of this research indicate the possibility of using Micro Shell as a new filler.

The purpose of this study is to analyze the side effects (ADR) of Traditional Chinese Medicine (TCM) injections by age, injection type, symptoms, and causes, and to find preventive solutions for ADR. For the ADR of TCM injection data collected during the search period from January 1, 2010 to December 31, 2020, the correlation between each section was analyzed by subdividing it into age, injection type, symptoms and causes. CNKI, PubMed, and EMBASE were used to collect the clinical data. 'Chinese herbal injection', 'Traditional Chinese Medicine injection', 'Chinese herbal injection side effect', 'Chinese herbal injection adverse drug reaction' were used for the keyword from the database. All data were collected mainly for TCM injection and the causes of ADR due to TCM injection. However, data not related to the relevant study or TCM injection were excluded from this study. Among a total of 941 studies collected during the search period from January 1, 2010 to December 31, 2020, a total of 10 studies were selected for final analysis. In 1462 clinical data sets, ADR by gender was higher in males than females. By age, 41 to 60 years were the most common. The incidence of ADR by injection type was highest in the blood regulating injection type. Data analysis showed Xueshuantong injection had the highest ADR. Among the symptoms of ADR, skin diseases were the most common. The most common cause of ADR was the unreasonable use of drugs. In China, for ADR management, the use of TCM injections is recommended according to the basic principles for the clinical use of TCM injections established by the Chinese government. In this study, we analyzed the current status and causes of ADR in TCM injections, and found a preventive solution. It is expected that it can be used as basic data to increase the usability of pharmacopuncture and herbal medicines in Korea in the future.

Open Data is an essential resource for the data industry. 'Act On Promotion Of The Provision And Use Of Public Data', enacted on July 30, 2013, mandates public institutions to manage the quality of Open Data and provide it to the public. Via such a legislation, the legal basis for the public to Open Data is prepared. Furthermore, public institutions are prohibited from developing and providing open data services that are duplicated or similar to those of the private sector, and private start-ups using open data are supported. However, as the demand for Open Data gradually increases, the cases of refusal to provide or interruption of Open Data held by public institutions are also increasing. Accordingly, the 'Open Data Mediation Committee' is established and operated so that the right to use data can be rescued through a simple dispute mediation procedure rather than complicated administrative litigation. The main issues dealt with in dispute settlement so far are usually the rights of third parties, such as open data including personal information, private information such as trade secrets, and copyrights. Plus, non-open data cannot be provided without the consent of the information subject. Rather than processing non-open data into open data through de-identification processing, positive results can be expected if consent is provided through active rights processing of the personal information subject. Not only can the Public Mydata Service be used by the information subject, but Open Data applicants will also be able to secure higher quality Open Data, which will have a positive impact on fostering the private data industry. This study derives a plan to establish a rights processing platform to enhance the usability of Open Data, including private information such as personal information, trade secrets, and copyright, which have become an issue when providing Open Data since 2014. With that, the proposals in this study are expected to serve as a stepping stone to revitalize private start-ups through the use of wide Open Data and improve public convenience through Public MyData services of information subjects.

Analysis of a bipartite (two-mode) network is a significant research area to understand the formation of social communities, economic systems, drug side effect topology, etc. in complex information systems. Most of the previous works talk about a projection-based model or latent feature model, which predicts the link based on singular similarity. The projection-based models suffer from the loss of structural information in the projected network and the latent feature is hardly present. This work proposes a novel method for link prediction in the bipartite network based on an ensemble of composite similarities, overcoming the issues of model-based and latent feature models. The proposed method analyzes the structure, neighborhood nodes as well as latent attributes between the nodes to predict the link in the network. To illustrate the proposed method, experiments are performed with five real-world data sets and compared with various state-of-art link prediction methods and it is inferred that this method outperforms with ~3% to ~9% higher using area under the precision-recall curve (AUC-PR) measure. This work holds great significance in the study of biological networks, e-commerce networks, complex web-based systems, networks of drug binding, enzyme protein, and other related networks in understanding the formation of such complex networks. Further, this study helps in link prediction and its usability for different purposes ranging from building intelligent systems to providing services in big data and web-based systems.
