In HEVC variable block size motion estimation, same search window data are duplicatedly used in each block size. It increases memory bandwidth, and it is difficult to exploit early termination. In this paper, largest block size and its corresponding smaller block sizes with same positions are performed at the same time. It reduces memory bandwidth and computation by reusing search window data and computation results. In the early termination, image quality can be degraded when it determines early termination by observing largest block size only, since smaller block sizes cannot be equally terminated due to their relative positions. So, in this paper, processing order of early termination is changed to perform smaller block sizes in turns. The designed motion estimation engine was described in Verilog HDL and it was synthesized and verified in 0.18um process technology. Its gate count and maximum operating frequency are 36,101 gates and 263.15 MHz, respectively.

Globalization has been accelerated in today's business environment. In this situation, the opening of economies can be either an opportunity or a treat for small and medium sized enterprises (SMEs) who have limited resources. Especially, managerial perception to the opening of economies carries on significant meaning because managerial perception determines future responses and strategies. Therefore, this study examined which innovation activities are related with SMEs' positive perception to the opening of economies. The activities of innovation are classified by types of generic strategy. Also, this study scrutinized the moderating effects of external search strategy and market entry strategy. In order to test hypotheses, this study analyzed data on Korean manufacturing firms collected in the Korean Innovation Survey (KIS). As a result, SMEs conducting innovation for differentiation strategy perceived the opening of economies positively. Search breadth and search depth moderated this relationship negatively and the first entry strategy moderated this relationship positively.

This study aims to investigate the Effect of Money Rush on Entrepreneurial Opportunity Recognition for college students in Busan and Gyeongnam area. We also examine whether Entrepreneurship has a mediating effect between Money Rush and Entrepreneurial Opportunity Recognition. Since the outbreak of COVID-19, digital transformation of the industry have greatly changed the world of work, and job insecurity is becoming more prevalent. As income inequality expands due to the disparity in asset income, the Money Rush phenomenon, which prefers to increase asset income through investment rather than earned income, is becoming common. Money Rush secures an income pipeline and is divided into side hustles and investments that actively utilize Leverage to maximize profits. The findings of this study confirm that Money Rush has a positive effect on Entrepreneurial Opportunity Recognition and a partially positive effect on Entrepreneurship. Entrepreneurship has a partial mediating effect between Money Rush and Entrepreneurial Opportunity Recognition. The study analysis is expected to contribute to strengthening college students' competencies in Entrepreneurial Opportunity Recognition and presenting the policy and practical directions necessary to promote Start-up.

Citizens should be sensitive to the complex and controversial SSIs (Socioscientific Issues), be able to make a responsible decision with evidence and empathy, and furthermore take political action for the larger welfare. The premise of this research is that understanding the nature of science (NOS) takes an important role when students and adults participate in the discourse on SSIs because SSI reasoning requires individuals to examine information and counter-information with skepticism. We therefore designed SSI programs that were incorporated with NOS by adapting a contextualized-reflective approach. The leading research question was to what extent SSI contexts contributed to promoting students' understanding of NOS. A total of 71 11th grade students participated in this program. The school was located in an urban city near the capital city of Seoul, South Korea. We designed SSI programs to cover the issues of genetically modified organisms, climate change, and nuclear energy. Each issue required four to six class periods to complete. We conducted pre- and post-program tests using the revised VNOS-C, recorded group discussions or debates and collected student worksheets to observe the increase of student NOS understanding. As a result of this program, students showed moderate improvement in their understanding of NOS.

주식시장은 자본주의 경제에 있어서 기업에게는 자본조달의 창구라는 기능을, 일반 투자자에게는 투자기회를 제공하고 국민경제적 입장에서는 자산과 부의 재분배 기능을 수행하는 등 매우 중요한 역할을 수행하고 있다. 따라서 국민경제를 이루는 거시경제학적 변수와 관계가 있을 것으로 보고 일부 연구자들은 거시 경제변수가 주가에 어떤 영향을 주는 지를 분석하고자 했다. 한편 주식시장에 있어서 인구통계학적 변수 역시 의미있는 변수이다. 특히 주식시장에 투자자로 직접 참여하는 투자자수는 더욱 중요하다. 본 연구는 단지 일부 거시경제학적 변수만의 효과를 다루었던 연구와 달리 인구통계학적 변수까지 종합적으로 고려하여 이들 변수가 주가에 미치는 영향을 분석할 수 있는 이론적인 토대를 정리하고 모형 도출을 위한 선행연구이다.

The Korean film, which reached its 100th anniversary, has achieved remarkable growth. However, contrary to the facts revealed to the outside, there existed chronic problems. Representatively, the problems were classified into four types: vertical integration problems, lack of support for art and independent films, lack of diversity in video content, and sluggish exports. Therefore, in order to continuously develop Korean films, this study explored the development methods of the domestic film industry using the window theory of opportunity. As a result of the research, the Korean film industry as a late chase was developed through strategies to enter new technologies and paradigms, and strategies to enter through low entry costs for existing digital platforms, active government intervention, and changes in regulations. Through this, it was revealed that the whole film ecosystem should ultimately go through symbiotic cooperation.

The purpose of this study is to propose implications by analyzing the textiles and clothing curriculum of vocational high schools. Literature and data were analyzed, surveys and FGI were conducted, and the following research results were derived. First, many schools chose 'Basic dress design' or 'Basic dress composition' as basic subjects. Through this, it was confirmed that technical training for practice is a priority for vocational schools, and that more discussion is needed regarding the lack of theoretical subjects. Second, similarly to the basic subjects, practical subjects offered are concentrated on 2 to 3 subjects. The teachers asserted that some subjects such as 'Knit apparel production' and the 'Leather and fur design production', which require a lot of equipment and advanced technology, cannot be offered without support from the government. Third, the NCS competency unit of the practical subjects is easy to proceed with the class or is closely concentrated on the type of manpower training presented by each department. Fourth, this study proposes that for technical education to expand students' choice, it is necessary to cultivate teachers competencies linked to the industry. The results of this study are expected to provide basic data on the organization of the next textiles and clothing professional curriculum and help understand vocational education at vocational high schools. In addition, it is believed that this study will contribute to developing and settling various subjects when the high school credit system is implemented by expanding students' choice of major-related subjects.
