There have been many efforts to identify and eliminate the direct causes of the construction accident, but many accidents are still occurring in the construction industry. The main reason for the construction accident is not because of ignorance of the causes, but because of safety insensitivity. This paper analyzes why construction workers feel safety insensitivity and how safety insensitivity varies depending on their age and work experience. A survey of 103 construction workers confirmed that systematic safety education is the most important factor in minimizing safety insensitivity of construction workers. On the other hand, economic reasons such as cost reduction were identified as the most tempting factor to increase safety insensitivity. In addition, the survey results showed that those in their 40s and 50s, the largest proportion of construction workers, have a significantly higher level of safety insensitivity than those in their 20s and 60s. These findings are expected to be valuable source that can be used to prevent construction safety accidents.

The present study explored how ADHD assessment, identification, and diagnosis were conducted in research through an overview of research papers on ADHD in the last 10 years. The collected studies were categorized and analyzed by topics including data collection settings, assessment and identification, coexistence with other disabilities, considerable variables throughout evaluation, and biological basis. They were categorized and analyzed according to the identification methods, the number of assessment(s) and the number of informant(s). The results were as follows: First, the assessment and identifying studies on children with ADHD were excessively biased toward clinical settings. Second, the majority of the previous studies explored more the development or validation of tools for the assessment and identifying of ADHD than the other topics. Finally, a high preference for the use of a multiple assessment method in identifying ADHD was found. However, considering methodological aspects, there was a lack of practical application of multi-step process such as including a personal interview, reviewing school records or direct observing rating criteria. Considering these results, we discussed an urgent need for the diagnosis and identification guidelines of ADHD for teachers to effectively identifying ADHD children at schools. The implications of school-based ADHD assessment and diagnosis research were suggested.

Through the comparative analysisand inductive research on main creation styles of Chinese, American and Japanese animation films, a conclusion can be given out, which means that the animation film style of each country can hardly be formed without their own traditional painting art, aesthetics habits and ways of thinking. It is these characteristics that form their unique animation film style. America emphasizes realism art, development and utilization of new technology, Japan pays sepcial attention totraditional painting art and comic stories. In business aspect, they bring about different business models relying on the experience of satisfying the diverse needs of domestic and global entertainment markets. When it comes to the content field, they carry forward universal values and meet the individualistic heroismso that a variety of business animation films and art animation films find their ways into the global market and acquire great popularity among audiences from all over the world. Through the comparasion of American and Japanese animation films, a new view to analyze the animation films of China is created. Animation creation is largely based on the need of socialist ideology from 50s to 80s. Even though the purposes of animation film creations returned to satisfying the diverse requirements of commercial markets and audiences, the consequences, such as the break gap of creations and talents, the lack of diverse creative styles and commercial market operation mechanism, sitll affect China's animation films today. Japan found thier position from the American model and became successful. Nowadays, China need find our own creative style and position from American model and Japanese model. And the systematic reformings that are detailed in the government managements, industry standards, internationalized talents cultivation and accumulation are the essential point.

This paper aims to examine the meaning of 'Xuan(玄)' in the cosmology and astronomy, especially in the view of Yang-xiong(揚雄) and Ge-hong(葛洪). The cosmology of the ancient China has opened a discussion about the Tian(天), through the discussion about the celestial structure, the structure and the location relation of the heaven & earth, in the Han-dynasty has been found a systematic theory. But in the ancient Chinese philosophy, the cosmology has been developed in the field of the astronomy & the Oriental calendar. In this context, Yang-xiong(揚雄) and Ge-hong(葛洪) have founded the system of the cosmology, it is as in the following. First, Yang-xiong criticized sharply the theory of Gaitian(蓋天說) and advanced the theory of Huntian(渾天說). And Ge-hong support the theory of Huntian(渾天說) and also accepted the theory of Xuanye(宣夜說). Second, Yang-xiong(揚雄) and Ge-hong(葛洪)'s cosmology is regarded as the theoretical premise of their cosmogony. As the discussion about the celestial structure, the structure and the location relation of the heaven & earth, both scholar discussed about the cause of creation, the differentiation process. And in the this context, they founded the cosmology as the concept 'Xuan'. Third, the concept 'Xuan' in the both scholar forms a philosophical system. Yang-xiong insisted that the concept 'Xuan' is the basis of the universe, the human-being and the society. While through realizing the concept 'Xuan', Ge-hong tried to pursue the human-being's agelessness and the eternal life. In this way, their view point of the cosmology is comprised of cosmogony & astronomy. With this perspective, they are going to found the system of their own philosophy.

IoT devices refer to embedded devices that can communicate with networks. Since there are various types of IoT devices and they are widely used around us, in the event of an attack, damages such as personal information leakage can occur depending on the type of device. While the security team analyzes IoT devices, they should target firmware as well as software interfaces since IoT devices are operated by both of them. However, the problem is that it is not easy to extract and analyze firmware and that it is not easy to manage product quality at a certain level even if the same target is analyzed according to the analyst's expertise within the security team. Therefore, in this paper, we intend to establish a vulnerability analysis process for the firmware of IoT devices and present available tools for each step. Besides, we organized the process from firmware acquisition to analysis of IoT devices produced by various commercial manufacturers, and we wanted to prove their validity by applying it directly to drone analysis by various manufacturers.

This research investigates the causes of infringements related to authors' moral rights which has most conflict among moral rights of authorship, through analysis of judicial precedents and compare whether there subsists any differences in viewpoints between judicial precedent trend and those on behind the scene of broadcast production. Copyright is divided into intellectual property and moral rights of authorship. Right to the integrity of the work is part of moral rights of authorship and produce one content and used in various media. When the edit is needed to fit the organization and advertisement time, advanced consultation from the rightful owner or written consent is needed. However, under the time pressure or ignorance of copyright, the arbitrary edits are made and content is used. This infringes the right of the integrity of the work. When we produce and use cinematographic works and other audiovisual works, there are considerable variablilies stemming from authorship, production cost and program staff. Therefore, prior conscent is needed to acquire and use the copyright in a proper manner. However, due to production-oriented environment and low understanding of the copyright protection, we usually depend on the users' work practices rhather than insufficiency of copyright laws in dealing with the infringement of right to the industry. In conclusion, we need to provide meticulous work manual and to focus on systematic eduction of professional copyright manpower.

This study aims to obtain basic data for systematic restoration by analyzing the monitoring results of the Shimwon Valley Ecological Landscape Restoration Project area in Jirisan National Park. In 2017, when the restoration project was completed, 12 monitoring plots and 4 control plots were installed for vegetation monitoring, and changes in the relative dominance, species diversity index and similarity between 2017 and 2020 were analyzed. The species diversity index of the surveyed areas where trees were planted during the restoration project was 0-1.4552, and the similarity index with the control group was 0% except for one survey area at 1.32%. The very low species diversity index and similarity index in the survey areas were attributed to the loss of trees planted during the restoration project due to death, damage by wild boars, or erosion by running water. On the other hand, the species diversity index was 0.9538-2.3222 in the monitoring plot where no tree was planted, and the similarity index was analyzed to be as high as 8.33%. It is necessary to continue the long-term monitoring for the development of ecological landscape restoration methods in the national park and analysis of the succession in monitoring plots where no trees were planted.

An average of two to three typhoons that occur in the Philippines or Taiwan pass through Korea each year owing to the influence of the geographical location and western winds. Because Jinhae Bay is known as Korea's representative typhoon refuge, it is filled with ships during typhoons and later becomes saturated with ships anchored to the surrounding routes. If a strong wind drags an anchored ship, a collision accident may occur because of the short distance between the ships. Therefore, a systematic anchoring safety management of Jinhae Bay is required. In this study, the minimum wind speeds of a dragging anchor based on the water depths of Jinhae Bay anchorages were investigated. When 7-9 shackles were given, the minimum wind speeds were 48-63, 46-61, and 39-54 knots at depths of 20, 35, and 50 m, respectively. As the water depth increased, the length of the cable laid on the sea bed became shorter than 5 m owing to the external force, and the minimum wind speed showed a significant difference of 4-8 knots. In addition, ships with high holding power anchors (AC-14 type) had higher minimum wind speeds than ships with conventional anchors (ASS type). Finally, it was confirmed that at a depth of 50 m, dragging easily occurred even when a high holding power anchor was applied.
