  • Recently, the government is taking new approaches to change the fact that the accident rate and accident death rate of the construction industry account for a high percentage of the whole industry. Especially, it is investing heavily in the development of construction technology that is fused with ICT technology in line with the current trend of the 4th Industrial Revolution. In order to cope with this situation, this paper proposed a concept to recognize and share the work situation information between the construction machine driver and the surrounding worker to enhance the safety in the place where construction machines are operated. In order to realize the part of the concept, we applied image processing technology using camera based on artificial intelligence to earth-moving work. Especially, we implemented an algorithm that can recognize the surrounding worker's circumstance and identify the risk situation through the experiment using the compaction equipment. and image processing algorithm based on YOLO-v3. This algorithm processes 15.06 frames per second in video and can recognize danger situation around construction machine with accuracy of 90.48%. We will contribute to the prevention of safety accidents at the construction site by utilizing this technology in the future.

  • EIA consultation is a final decision-making process that enables a variety of stakeholders to participate in and to share important information about the expected environmental impacts caused by development projects. However, this process is often undermined through re-consultation processes by significant changes in the proposed plans. EIA re-consultation is a necessary process when an approved plan needs to be changed for a variety of importantreasons including the changes of land use, delay of construction, and surrounding environments. EIA re-consultation is also important to resolve conflicts among stakeholders and to respond flexibly to unexpected changes in surrounding environment. This study aims to analyze the operation status and the problems of current institutional systems of EIA re-consultation, and to draw implications by reviewing institutional systems of other countries such as U.S. EU, Scotland, and Japan. On the basis of the previous analysis, we propose recommendations to improve the existing EIA re-consultation process. We expect this study helps understand operation status and problems of EIA re-consultation, and provides meaningful implications to improve the existing institutional systems and practice of re-consultation.

  • In contrast to standard train tracks, tramlines are often set along public roads, with trams running among pedestrians and other vehicles. In some cities and towns, trams and buses share the same routes and stations. Under the current investment appraisal system, trams are classified into light rail when predicting traffic demand and calculating benefits, but in the case of non-capital areas, it is notable that the origin-destination and transit lines of buses are not provided in the Korea Transport Database distribution data. Due to this problem, it is difficult to reflect proper mode changing behaviors between route buses and trams. This study examines the impact on tramlines of bus routes that are not currently considered in non-capital areas. Following an analysis of the effect of tram projects according to whether bus routes are considered or not, an improvement in methodology is proposed. Through this study, it is expected that the investment appraisal system for the planning of new tramlines will be improved in the future.

  • This paper proposes the DC-link voltage design method of Type 4 wind turbine that minimizes power loss and satisfies the High Voltage Ride Through(HVRT) function requirements of the transmission system operator. The Type 4 wind turbine used for large-capacity offshore wind turbine consists of the Back-to-Back converter in which the converter linked to the power grid and the inverter linked to the wind turbine share the DC-link. When the grid high voltage fault occurs in the Type 4 wind turbine, if the DC-link voltage is insufficient compared to the fault voltage level, the current controller of the grid-side converter can't operate smoothly due to over modulation. Therefore, to satisfy the HVRT function, the DC-link voltage should be designed based on the voltage level of high voltage fault. However, steady-state switching losses increase further as the DC-link voltage increases. Therefore, the considerations should be included for the loss to be increased when the DC-link voltage is designed significantly. In this paper, the design method for the DC-link voltage considered the fault voltage level and the loss is explained, and the validity of the proposed design method is verified through the HVRT function simulation based on the PSCAD model of the 2MVA Type 4 wind turbine.

  • ICAO has recommended data-based aviation safety management and decision-making systems through Annex 19(Safety Management) and Doc 9859(Safety Management Manual), stressing that safety can be greatly improved by sharing aviation safety information throughout the industry. Accordingly, advanced aviation countries have built infrastructure to collect and analyze various aviation safety data in an integrated manner, and also tried to spread identified major safety issues across the industry. On the other hand, in Korea, each stakeholder collects, manages and analyzes safety data individually, so there is a limit to use them in integrative manner. In addition, the scope of using and sharing aviation safety information such as analysis result is also focused on safety management at the national government level, which is insufficient to be shared throughout the industry. Accordingly, the purpose of this study is to present a plan to share and utilize the domestic aviation safety information. To do this, we compare the current situation between FAA and domestic industry and suggest the improvement plans.

  • Many countries and companies are pursuing and developing Artificial intelligence as it is the core technology of the 4th industrial revolution. Global IT companies such as Apple, Microsoft, Amazon, Google and Samsung have all released their own AI assistant hardware products, hoping to increase customer loyalty and capture market share. Competition within the industry for AI agent is intense. AI assistant products that command the biggest market shares and customer loyalty have a higher chance of becoming the industry standard. This study analyzed the current status of major overseas and domestic IT companies in the field of artificial intelligence, and suggested future strategic directions for voice UI technology development and user satisfaction. In terms of B2B technology, it is recommended that IT companies use cloud computing to store big data, innovative artificial intelligence technologies and natural language technologies. Offering voice recognition technologies on the cloud enables smaller companies to take advantage of such technologies at considerably less expense. Companies also consider using GPT-3(Generative Pre-trained Transformer 3) an open source artificial intelligence language processing software that can generate very natural human-like interactions and high levels of user satisfaction. There is a need to increase usefulness and usability to enhance user satisfaction. This study has practical and theoretical implications for industry and academia.

  • Lacquer, in addition to high-end crafts such as lacquerware inlaid with mother-of-pearl, was an important strategic material used in a wide range of fields such as industry, architecture, and munitions during the Japanese colonial era. In particular, as the demand for lacquer used in munitions soared in the 1940s when the war started, a ticket system was introduced to restrict its distribution. Meanwhile, Japan experienced a chronic shortage of lacquer as a result of the rapidly increasing demand for it, and thus went on to import Chinese lacquer after the late 19th century. After the 1910s, the market share of Chinese lacquer reached 90%, and the local situation in China began to affect the supply and demand for lacquer in Japan. To counteract the issue, the Japanese government increased the production of lacquer in Joseon. As for the project to increase lacquer production in Joseon, objective indicators were prepared through a number of tests in the 1910s and 20s, which paved the way for the project to begin in earnest in the 1930s. Lacquer trees were planted and training classes on how to collect lacquer were held throughout the country. The Japanese government promoted the lacquer production industry as a promising side job for Koreans. The project, implemented in various parts of the country, reaped fruitful results, and it provided the basis for lacquer production in Korea that has continued to this day. At that time, the major regions in the southern part of the country where the project was concentrated were Wonju, Okcheon, and Hamyang, regions that are still known today as major production sites. The improved method of collecting lacquer taught to Koreans by the Japanese has now become the main method of collecting lacquer in Korea. This study attempts to identify the current status of the project to increase lacquer production through various records from the Japanese colonial era with a view to contributing to the study of modern lacquer craft history.

  • Pansori has both the features of drama and music. In 19th century, prime time of pansori, it had balance of the features between drama and music. But after the late 19th century, pansori has lost the features of drama, and it has been changed into a music centered art performance. This is the phenomenon came from that the upper class accepted and dominated the pansori which had been a performance art of the lower class. The Korean upper class people tend to disdain drama, but to revere music. Nerremsae is dramatic action and ballim is musical gesture in pansori. In 19th century, pansori had plenty of nerremsae, which provided a elaborative symbolic system after the conventional rule of drama. However current pansori actors use only ballim except nerreumsae. Chuimsae like 'ulssigu' is the way to participate in pansori by audience. The actor provides the space for the audience to fill it after inducement by drummer. Through the chuimsae, actor, drummer, and audience share the sympathetic emotional experiences. However the audience in these days do not do chuimsae, but do applause like in western dramas. In western dramas, distinction between tragedy and comedy is relatively clear. The tragedy is constantly tragedy, and the comedy is also constantly comedy. However joy and sorrow are coexisted in Korean pansori. These two contradictory emotions are collided and produce a new strong emotion in a pansori. This is one of very important feature of pansori. Even though each of tragedy and comedy reveals the only one side of life, pansori comprehensively reveals a total human life. However these strong emotions have been much weakened nowadays. Currently pansori has been much declined. For restoration of pansori, it is necessary to revive the drama side in pansori performances.
