  • Carbon nanotubes (CNTs) were synthesized by inductively coupled plasma CVD at $450^{\circ}C$. CNTs were grown on the 1-nm-thick Fe-Ni-Co with $C_2H_2$ and $H_2$ at different pressures and plasma powers. CNTs were grown longer in height as the $H_{\alpha}/CH$ ratios became lower by decreasing plasma powers and increasing growth pressures.

  • The thermal oxidation recipe has been optimized for very thin (12 nm) capacitor oxide for Mega bit DRAM. The time dependent dielectric breakdown characteristics show that the breakdown voltage and time to breakdown are very high and uniform, indication that our oxide is defect free and suitable for DRAM capacitor dielectric. To our knowledge this is the best oxide quality obtained up tp now around 10 nm.

  • 플라즈마 열화학기상 증착법으로 Fe-Ni-Co 3원계 측매합금을 이용하여 $442^{\circ}C$의 저온에서 다중벽 탄소나노튜브를 합성하였다. 수소의 유량이 일정할 때 아세틸렌의 유량이 감소함에 따라 성장속도가 증가하였다. 합성된 탄소나노튜브는 약 8.4 nm의 직경과 $5.5\;{\mu}m$의 길이를 보였으며, 기판에 대해 수직으로 성장되었다. 4인치 웨이퍼 위에서도 전면적에서 균일한 성장을 보였다.

  • 영상 스티칭은 다수의 영상을 넓은 시야각을 갖는 하나의 영상으로 합성하여 사용자들에게 몰입감과 현장감을 제공하는 기술이다. 그러나 영상에 시차(Parallax)가 존재하는 경우 스티칭된 영상에서 왜곡이 발생할 수 있는데 이는 사용자의 몰입을 방해할 수 있다. 따라서 스티칭 영상의 다양한 활용을 위해서는 시차로 인한 왜곡을 최소화하여 자연스러운 스티칭 영상을 만드는 것이 중요하다. 기존 호모그래피 추정 방법으로 발생할 수 있는 고스트 현상을 최소화하기 위해서 seam 기반 스티칭 방법이 사용되었지만, 단순히 작은 특징값을 따라 생성된 seam은 사물 영역 정보가 반영되지 않아 seam이 특징이 있는 부분을 지나가면서 시차 왜곡이 발생할 수 있다. 이에 본 논문에서는 딥러닝 기반의 MegaDepth를 활용한 depth 예측 정보를 에너지 함수 기반의 seam 생성 행렬의 가중치로 사용하여 seam이 사물을 피해 생성되면서 시차가 작은 영역으로 유도되도록 하는 seam optimization 기법을 제안한다.

  • Recently as construction projects have been complicated, it has been wearing thin to draw on their personal experiences for management. Although the advance of IT, using the technology for construction is insufficient in contrast to other industries. BIM has been steadily used in construction projects, but it is not easy to find the case of successful use. This research considers ways in which BIM technology can be applied to useful management on a construction site and derives a method of application of using BIM for a Mega-complex Building Project especially.

  • Traditional project management theory is based on a three-dimensional life cycle approach where the project managerseeks to optimize the dimensions of cost-schedule-technical (quality or design). This paper reports the findings of a case study analysis of two complex mega-projects in Michigan which confirm the findings of previous research and illustrates the use of a framework for five-dimensional project management (5DPM) that is for conceptualizing a complex project's scope of work. The framework elevates the recognition that the project's social/political context and the financial arrangements create complexity adding two new dimensions. This paper also demonstrates a methodology to graphically display a project's complexity to better understand and prioritize the available resources. The result is a "complexity footprint" that may help a complex project manager identify the boundary between controllable and uncontrollable projects impacts. The paper finds that applying 5DPM to the two case study projects has given the project delivery team a tool which is actually adding value to the complex project management process.

  • This study investigates the impact of mega-influencers and micro-influencers on consumer trust, brand attitude, and purchase intention within the beauty industry. Methods: A survey of 160 adults was conducted in March 2024, analyzing responses to the influence of a beauty mega-influencer ("Isa Bae") and a micro-influencer ("Day Beauty"). Participants were surveyed online over two weeks, and the data were analyzed using statistical tools to compare the influence of both types of influencers. Results: The results indicated that mega-influencers had a more substantial effect on reliability and brand attitude compared to micro-influencers, although both types of influencers significantly influenced purchase intentions. Influencer attractiveness and expertise emerged as critical factors in shaping consumer perceptions and behaviors. Conclusion: This study provides insights into optimizing influencer marketing strategies by leveraging the distinct characteristics and scales of influencers to enhance consumer engagement and brand loyalty. The findings underscore the importance of choosing the appropriate influencer type to maximize marketing effectiveness and consumer trust in the digital marketing landscape.

  • The strategy of "soft power" in the foreign and internal policies of modern Russia is one of the important factors in the implementation of public policies, and the influence of soft power is increasingly becoming stronger and gaining new forms and methods of implementation. The Russian government exerts efforts to form a positive image of Russia in the international arena, in order to strengthen the country's competitiveness, based on active use of "soft power." Currently, Russian cultural policy is developing in two main directions. In the internal policy sphere, the Russian government emphasizes national unity and civic solidarity, and fosters a sense of patriotism and national pride. In the sphere of foreign policy, the Russian government is attempting to regain its status as a great power and to create a new image of Russia that is different from that of the former Soviet Russia. In this article, we examine and analyze various aspects of the hidden political mechanisms involved in mega-sporting events, in particular the Sochi Olympics, from the viewpoint of Russian internal and foreign policy. We address the major functions of mega-sporting events and their influence in the political realm. The political impact of mega-sports projects can even compensate for economic losses incurred during the preparation and hosting of the Olympic games. In this respect, we can define mega-sporting events as one of the main components of soft power; such events reflect the basic directions of internal and foreign policy in post-Soviet Russia, which are to form and promote an image of Russia using national branding. In order to fairly and objectively analyze the recognition and perception held by Russians of the significance of mega-sporting events, in this work, we carefully studied the results of various surveys conducted by the Russian research organization VCIOM (Russian Public Opinion Research Center) before and after Russia hosted the Winter Olympic games in Sochi (2014) and the Summer Olympic games in Kazan (2013). Furthermore, on the basis of the ranking of national brands by Simon Anholt (Anholt Nation Brands Index - NBI), and on the basis of the ranking of 100 national brands conducted by the British consulting company "Brand Finance" (Brand Finance Nation Brands 100), we minutely trace the development and qualitative change in Russia's image and the role of the mega-sporting projects. This article also examines the Kremlin's internal and foreign policies that were successfully carried out in practical terms. This study contributes to the understanding of the value of mega-sporting events from the point of view of cultural policy of the current ruling party of Russia. This standpoint allows us to outline the main directions of Russian cultural policy and to suggest perspectives on the branding strategy of modern Russia, including strategies related to consolidating Russia's position in the international arena.

  • This study focuses on the potential for creating spatial and atmospheric effects in small theaters using mobile stage equipment, without being constrained by physical space or theater facilities, for mega musical productions. With the continuous growth of mega musicals in the domestic market, the study analyzes the distribution and sales of musical works in Korea and proposes methods for creating spatial effects in university musical education to facilitate the production of mega musicals in small theaters. The mobile stage equipment is designed based on the principle of the periaktoi, a stage mechanism used in ancient Greek theater and the characteristics of mobile stage equipment used in musicals such as <Notre Dame de Paris> and <Laundry>. The mobile stage equipment is a four-sided column-shaped device, which is applied to the musical <Les Misérables> to derive the potential for creating spatial effects, representing the inner state of characters, and forming the mood of the drama. The study is expected to provide opportunities for performing mega musical productions in university musical education and to contribute to the development of the musical industry and education. The utilization of mobile stage equipment demonstrates the possibility of producing mega musical productions in small theaters.
