In the 1970s, Korea actively produced so many animated works which is called the "golden age" of korean animation. However, Korea imported and subcontracted foreign animations than creating original works and, there has been a constant controversy that many of the korean animations imitated foreign works. Therefore, this paper aims to analyze the factors that caused this and its patterns, focusing on works suspected of plagiarism in Korean animation during the 1970s and 1980s. First, the focus will be on the definition and composition of plagiarism in art creation, secondly, on the political-ideological, industrial-administrational, production-structural, and copyright awareness aspects of the factors of plagiarized animation. Thirdly, 30 korean animations produced at the time will be analyzed on the degree of design theft and plagiarism based on six criteria focusing on characters' shapes and color arrangements. By analyzing the social factors and patterns of plagiarism, this study aims to provide a social and cultural understanding of academic value about the process of korean animation's development.

Crowdedness management at subway platforms is essential to improve services, including the prevention of train delays and ensuring passenger safety. Establishing effective crowdedness mitigation measures for platforms requires accurate estimation of the congestion level. There are temporal and spatial constraints since crowdedness on subway platforms is assessed at certain locations every 1-2 years by hand counting. However, smart cards generate real-time big data 24 hours a day and could be used in estimating congestion. This study proposes a model based on data from transit cards to estimate crowdedness dynamically. Crowdedness was defined as demand, which can be translated into passengers dynamically moving along a subway network. The trajectory of an individual passenger can be identified through this model. Passenger flow that concentrates or disperses at a platform is also calculated every minute. Lastly, the platform congestion level is estimated based on effective waiting areas for each platform structure.

During the major sections of the network, Software-defined network control technology for the network area corresponding to the transmission network is becoming a change in network-controlled environments utilizing network operation and provisioning across the network industry. Currently development is underway along with the deployment of PTN equipment and configuration for provisioning is being phased out. It is actively introducing establishment of SDN-based control system while constructing provisioning of PTN equipment from actual commercial network. Therefore, in this thesis, we are going to look at the contents and trends of SDN systems in packet-based transmission networks based on PTN and use them in research on OpenDaylight, an open source for configuring SDN. It then Network Operator will study the software defined control techniques for operational education.

In this study, the concept of emotional labor and AI(appreciative inquiry) are connected to examine how acceptance of AI, which is related to changes in hospital organizational culture, affects nurses' emotional labor, organizational commitment, and job satisfaction. For this purpose, the data collected from 156 nurses working at a major hospital were analyzed using structural equation modeling. The findings of this study are as follows: First, nurses' acceptance of AI had a significant positive effect on deep acting but not on surface acting. Second, deep acting had a significant positive effect on organizational commitment, but surface acting did not. Third, nurses' organizational commitment had a significant positive effect on job satisfaction. Fourth, deep acting significantly mediated the relationship between nurses' acceptance of AI and organizational commitment, but surface acting did not. Fifth, deep acting and organizational commitment significantly mediated the relationship between nurses' acceptance of AI and job satisfaction, but surface acting and organizational commitment did not. Theoretical and practical implications are provided based on the relationships between the variables found in this study.

We applied to the rapid assessment of ES method to Ansan city and local registers selected Ecosystem assets that considered to space of ES. Ecosystem assets were measured 5 types Likert scale about 37 indicators of ES and confirm the main ES through the basic statistics. Furthermore Ecosystem assets classified according to similar character of ES. Ecosystem assets of Ansan were selected 47 site and Local climate regulation, Research and education, Primary production was high among the ES indicators. As a result two main group deduced that ecological education group(such as Research and education, Habitat) and safety regulation group(such as Air regulation, Fire regulation) through the factor analysis. In terms of location characteristics of each group, the ecological education-centered ecosystem assets were located near the downtown area, while the safety regulation group was located at the outskirts, such as mountains and coasts. This indicates that the ecological education about the habitat provision can be achieved in Ansan city downtown area and that outskirts should be approached from the aspect of ecological function to establish a plan.

A pavement construction process consists of series of lay-down operation for pavement materials to form a designated thickness and compaction operation for the lay-down layer to form a designated strength. A technological breakthrough in pavement compaction equipment was made in last 15 years in western countries: intelligent compaction roller, that is equipped with GPS along with other pavement response sensors is becoming a game-changer in pavement construction. This paper introduces AR system that may be used in asphalt pavement compaction operation using intelligent compactor. Since AR technology is very new concept in road construction society, a suggestion for accompanying education program was also made for specific task group in pavement compaction operation. Since AR technology has not been introduced in asphalt pavement compaction operation, the AR compaction management would lead the construction quality of asphalt pavement to the beyond level.
