This study assessed the maintenance plan of the Shimbashi-Toranomon Development Area in Japan, which has recently been completed using the three-dimensional road system. In the main relevant law system, a three-dimensional road system, which enables the construction of buildings above and below the road, was applied. The specific construction regulations applying the financing power and knowledge of private business operators were applied. In the development district, city maintenance guidelines were established, and housing and shopping malls were regulated. This purpose was to promote change, unity of distance, effective use of land, and continuous urban revitalization with charm and vitality. The main features of the maintenance plan were accessibility and greenery, comfort and a sophisticated design, and a maintenance concept utilizing historical buildings and road space through the participation of local residents and the opinions of related committees. In addition, in the case of the construction of the upper and lower roads, the construction restrictions were relaxed, and the separation of the roads and the undergrounding of electric poles were promoted. The main aim was to improve the convenience of the residents and produce a pleasant road landscape.

This paper attempts to analyze the inner and outer structure of royal tombs that were built during the Joseon Period. This analysis is based on the relevant historical records and they were restored through visual composition in order to compare the features of Joseon royal tombs with those of Goryeo royal tombs and common tombs of the Joseon Period. Royal tombs of the Joseon Dynasty are structurally solid and contain a variety of artistic ornaments that symbolize guardian deities both inside and outside to protect the owners of the tombs for a long time. According to historical records such as Sejong sillok oryeui (Five Rites of State from the Annals of King Sejong) and Gukjo oryeui (Five Rites of State), it is presumed that the inner structure of royal tombs dating back to the early Joseon Period consisted of a stone chamber and that the byeongpungseok and nanganseok were built outside of the tomb. However, ever since King Sejo left it in his will not to make a stone chamber in his tomb, the royal tombs began to follow a new pattern, a burial pit outside the coffin filled with lime powder. Gukjo sangnye bopyeon (Supplement Book of the State Funeral Rites), which was compiled during the reign of King Yeongjo, is a book that shows how the royal tombs were formed in the late Joseon Period. The book explains in detail how lime powder was used to fill the burial pit of royal tombs. The byeongpungseok used during the late Joseon Period were engraved with peony flowers, while those previously made were engraved with twelve spirit warriors. Peony designs were frequently used to decorate the items of royal families, and the use of peony designs in tombs reflects the idea of regarding the royal tombs as an everyday living space for the deceased.

The analysis of the similarities and redundancies among R&D projects is important for the efficient investment of government budgets. When government R&D projects are planned, the redundancies of research tasks are examined by institutions specializing in research management, relevant offices and departments, and the government to prevent redundant funding. However, as existing similarity analyses depend on methods wherein new task proposals and existing R&D project proposals are compared and looked up based on keywords. This results in vulnerability wherein similarity cannot be accurately measured in the event of partial modifications of the task name or technical substitutions. This study aims to use patent information as characteristics by which R&D project documents can be identified. The patent data used is based on materials officially published by the government's R&D patent trend survey project (http://ipas.rndip.re.kr). The study aims to propose a method by which patent information can be used to analyze the similarity and redundancy among R&D projects when new projects are entered. For this purpose, a similarity measurement model based on set theory and probability theory is presented. The presented measurement model is implemented into an actual system to identify redundant documents, and calculate and show their similarity.

This paper aims to explore ways to develop the arbitration industry in Korea. The prospects for the promotion of the arbitration industry in Korea are never dim. International arbitration competitiveness is somewhat lower than its competitors at present, but the international economic base to support it is solid, and the domestic arbitration environment seems to be sufficient to support the development possibility of arbitration. Since geographical and economic factors have already been defined, Korea must at least improve the arbitration act with passion and vision for the best one. The arbitration act that is the most accessible to arbitration consumers is the best arbitration act. The important thing is to have an arbitration act that makes people want to use more than litigation or other dispute resolution procedures. There is no hope of remaining as a "second mover" in the field of arbitration law. One should have a will and ambition to become a "first mover" even if it is risky. Considering the situation of the current arbitration law, it is necessary to start an arbitration appeal system in order to become a consumer-friendly arbitration law, and it is necessary to examine ways of integrating the grant of execution clause and enforcement application procedures. The abolition of the condition of Article 35 of the Arbitration Act, which rules the validity of the arbitration award, will help promote international arbitration. Exclusion agreements of setting aside against arbitration awards must also be fully recognized. It is also important to publish a widely cited international arbitration journal. In order to respond to the fourth industrial revolution era, it is necessary to support the establishment of a dispute resolution system that utilizes IT technology. In order to actively engage the arbitrators in the market, it is necessary to abolish the regulations that exist in the Attorneys-at-Law Act. There is also a need to allocate more budget to educate arbitration consumers and to establish arbitration training centers to strengthen domestic arbitration education. It is also necessary to evaluate and verify the Arbitration Promotion Act so that it can achieve results. In the international arbitration market, competition is fierce and competitors are already taking the initiative, so in order not to miss the timing, Korea needs to activate international arbitration first. In order to activate international arbitration, the arbitration body needs to be managed with the same mobility and strategy as the agency in the marketplace. In Korea, unlike in Singapore and Hong Kong, it is necessary to recognize that the size of the domestic arbitration market is very likely to increase sharply due to the economic size of the country and the large market potential it can bring from litigation. In order to promote the arbitration industry, what is most important is to make arbitration activities in accordance with the principles of the market and to establish an institutional basis to enable competition. It is urgently required to change the perception of the relevant government departments and arbitration officials.

Because of the characteristics of game software, it is important to quickly identify and reflect users' needs into game software after its launch. However, most sites such as the Google Play Store, where users can download games and post reviews, provide only very limited and ambiguous classification categories for game reviews. Therefore, in this paper, we develop an automatic classification system for game reviews that categorizes reviews into categories that are clearer and more useful for game providers. The developed system converts words in reviews into vectors using word2vec, which is a representative word embedding model, and classifies reviews into the most relevant categories by measuring the similarity between those vectors and each category. Especially, in order to choose the best similarity measure that directly affects the classification performance of the system, we have compared the performance of three representative similarity measures, the Euclidean similarity, cosine similarity, and the extended Jaccard similarity, in a real environment. Furthermore, to allow a review to be classified into multiple categories, we use a threshold-based multi-category classification method. Through experiments on real reviews collected from Google Play Store, we have confirmed that the system achieved up to 95% accuracy.

Government publications, as the important media of communication between the public and the government, have served as informational sources to provide a variety of information. Although technological development led into sharp changes in the types and services of government publications, the Korean service of government publications has yet to respond to the changes properly. The web service of government publications is provided only in the archives-based way with no consideration of the characteristics of the government publications, so that it is considerably difficult to use the service. Therefore, based on literature research, request of information disclosure, website survey, and interviews, this work overhauled the web service of government publications provided by the National Archives of Korea, and suggested an improvement plan of the service. This study is meaningful in the point that it suggested an improvement plan for the web service of government publications, which have been managed as a sort of archives but have been placed in the blind spot of service, through interviews with the persons in charge of government publications in relevant public organizations and the National Archives of Korea.

In this paper, the purpose of this paper is to lay the foundation for the search system by using and building an online search engine suitable for the search domain and enabling search, conversion, integration and sharing of information. It is to use the ontology to infer hierarchical relationships, deduce objects based on that layer, and extract attributes to search areas that are relevant to the data that the user wants. In order to search for information in this way, the information search system was implemented by entering key words related to 'qualifications'. The implemented system arranged the meaning and relationship of each attribute online so that the general public can search information quickly, easily, and accurately. In addition, the implementation results were compared with two different search engines. Comparable search engines are Naver and Daum, the two major search engines. The search engine of this study, which was built using an ontology suitable for the search domain to perform searches using the semantic web, was evaluated to have excellent results. However, it is thought that a more formalized online location is necessary to increase the accuracy and reliability of search engines and to include more comprehensive categories of search terms.

Peach flesh color is commercially important criteria for classification and has implications for nutritional quality. To breed new yellow-fleshed peach cultivar many cross seedlings and generations should be maintained. Therefore it is necessary to develop early selection molecular markers for screening cross seedlings and germplasm with economically important traits to increase breeding efficiency. For the comparison of transcription profiles in peach varieties with a different flesh color expression, two cDNA libraries were constructed. Differences in gene expression between yellow-fleshed peach cultivar, 'Changhowon Hwangdo' and white-fleshed peach cultivar, 'Mibaekdo' were analyzed by next-generation sequencing (NGS). Expressed sequence tag (EST) of clones from the two varieties was selected for nucleotide sequence determination and homology searches. Putative single nucleotide polymorphisms (SNPs) were screened from peach EST contigs by high resolution melting (HRM) analysis, SNP ID ppa002847m:cds and ppa002540m:cds displayed specific difference between 17 yellow-fleshed and 21 white-fleshed peach varieties. The SNP markers for distinguishing yellow and white fleshed peach varieties by HRM analysis offers the opportunity to use early selection. This SNP markers could be useful for marker assisted breeding and provide a good reference for relevant research on molecular mechanisms of color variation in peach varieties.

Recently, the smart home environment is expected to be a platform that collects, integrates, and utilizes various data through convergence with wireless information and communication technology. In fact, the number of smart devices with various sensors is increasing inside smart homes. The amount of data that needs to be processed by the increased number of smart devices is also increasing, and big data processing systems are actively being introduced to handle it effectively. However, traditional big data processing systems have all requests directed to cluster drivers before they are allocated to distributed nodes, leading to reduced cluster-wide performance sharing as cluster drivers managing segmentation tasks become bottlenecks. In particular, there is a greater delay rate on smart home devices that constantly request small data processing. Thus, in this paper, we design a Apriori-based big data system for effective data processing in smart home environments where frequent requests occur at the same time. According to the performance evaluation results of the proposed system, the data processing time was reduced by up to 38.6% from at least 19.2% compared to the existing system. The reason for this result is related to the type of data being measured. Because the amount of data collected in a smart home environment is large, the use of cache servers plays a major role in data processing, and association analysis with Apriori algorithms stores highly relevant sensor data in the cache.

The flammable liquid conductivity is an important factor in determining the generation of electrostatic in fire and explosion hazardous areas, so it is necessary to study the physical properties of flammable liquids. In particular, the relevant liquid conductivity in the process of handling flammable liquids in relation to the risk assessment and risk control in fire and explosion hazard areas, such as chemical plants, is classified as a main evaluation item according to the IEC standard, and it is necessary to have flammable liquid conductivity measuring devices and related data are required depending on the handling conditions of the material, such as temperature and mixing ratio for preventing the fire and explosion related to electrostatic. In addition, IEC 60079-32-2 [Explosive Atmospheres-Part 32-2 (Electrostatic hazards-Tests)] refers to the measuring device standard and the conductivity of a single substance. It was concluded that there is no measurement data according to the handling conditions such as mixing ratio of flammable liquid and temperature together with the use and measurement examples. We have developed the measurement reliability by improving the structure, material and measurement method of measuring device by referring to the IEC standard. We have developed a measurement device that is developed and manufactured by itself. The test results of flammable liquid conductivity measurement and the data of the NFPA 77 (Recommended Practice on Static Electricity) Annex B Table B.2 Static Electric Characteristic of Liquids were compared and verified by conducting the conductivity measurement of the flammable liquid handled in the fire and explosion hazardous place by using Measuring / Data Acquisition / Processing / PC Communication. It will contribute to the prevention of static electricity related disaster by taking preliminary measures for fire and explosion prevention by providing technical guidance for static electricity risk assessment and risk control through flammable liquid conductivity measurement experiment. In addition, based on the experimental results, it is possible to create a big data base by constructing electrostatic physical characteristic data of flammable liquids by process and material. Also, it is analyzed that it will contribute to the foundation composition for adding the specific information of conductivity of flammable liquid to the physical and chemical characteristics of MSDS.
