최근 선진국에서의 IT 기술발전은 매우 급속하여 현장활용을 위한 개발 활동이 채 따라가지 못할 정도이다. 첨단기술의 발전과 이의 응용을 위한 개발과의 격차는 농업기상분야에서도 마찬가지이다. 여기에서는 농업기상정보 교환을 위해 그 활용이 증대될 것으로 기대되는 기술들의 발전현황을 다루고 있다. 한가지 새겨 두어야 할 점은 IT기술 발전은 단지 정보원에서 사용자에게로의 정보전달을 가속화하는데 사용되는 교환통로라는 점이다. 본 논문에서는 교환에 대한 정의 검토를 시도하였다. 결론적으로 여러 가지 논문 검토를 통해 살펴 본 바 교환은 "의미의 공유"라고 정의할 수 있다. 이들 논문에 의하면 실질적인 정보교환통로는 국가의 경제수준에 관계없이 매우 유사하였으며, 단지 차이가 있다면 일부 국가에서는 다른 나라에 비해 좀더 접근이 용이하다는 점뿐이었다. 보편적인 교환통로로는 신문, 농민신문, 라디오, TV, 팩스, 전자우편, 휴대폰 및 인터넷 웹을 들 수 있다. 한편 통신기술이 발전함에 따라 전 세계적으로 휴대폰의 유용성이 점차 높아지고 있다. 이러한 기술을 더욱 잘 활용하기 위해서는 이 기술을 이용할 사람들이 상세하지는 않더라도 최신기술을 운용하여 필요 자료를 획득하기 위한 기본적인 작동기술을 이해하는 것이 매우 중요하다. 첨단기술활용의 장애요인으로는 농업기상정보교환이 원래 상당한 자원을 요구하고, 정교한 농업모의모형을 구동하기 위해서는 많은 비용이 든다는 점이다.

This study takes a comprehensive look at how technological advances have changed the way 2D animation is created. Humans are constantly looking for new ways and technologies to express movement, which has led to many changes in the way 2D animation is produced. In this study, we will examine the impact of these changes on 2D animation production and explore the possibilities for future developments. In the early days of 2D animation, the production method was repeatedly changed by the invention of technologies such as celluloid sheets, rotoscopes, and multiplane cameras, while the advent of digital technology has led to revolutionary changes such as the development of CAPS(computer animation production systems), various digital tools, and the combination of 2D and 3D. In addition, the recent introduction of generative AI is rapidly changing the way 2D animation is produced by automatically handling various tasks. These advances have not only streamlined the production of animation, but have also reduced costs by shortening the production period, and greatly improved the quality of animation by making it easier to implement complex and sophisticated visual effects. The introduction of generative AI has pushed the boundaries of what can be represented in 2D animation. On the other hand, the introduction of digital technology has its drawbacks, as the mechanical and uniform style produced by digital tools can reduce originality and individuality, but advances in technology will open up the possibilities for 2D animation to be produced in a variety of ways, as it fosters the creation of new expressions and creative content.

The incorporation of technological advances in the field of clinical orthodontics to increase treatment efficiency has led to the development of customized appliances (Insignia$^{(R)}$), archwires (Suresmile$^{(R)}$), and the production of devices to enhance tooth movement (Acceledent$^{(R)}$). This review presents a comprehensive study of the literature concerning these products, and analyzes the available evidence of their efficiency. To date, one pilot study has evaluated the efficiency of the Insignia$^{(R)}$ system, three retrospective studies have assessed the efficiency of the Suresmile$^{(R)}$ system, and a few Acceledent$^{(R)}$ reports have described its effect on treatment time. Critical appraisal of the reviewed papers revealed that the efficiency of the Insignia$^{(R)}$ system cannot be confirmed based on the available evidence, while the use of Suresmile$^{(R)}$ can reduce overall treatment time in simple cases. The acceleration of tooth movement by Acceledent$^{(R)}$ devices has not yet been confirmed.

Over the past few decades, the impact of natural, manmade and natech (natural hazard triggering technological disasters) disasters has been devastating, affecting over 4.4 billion people. In spite of recent technological advances, the increasing frequency and intensity of natural disasters and the escalation of manmade threats is presenting a number of challenges that warrant immediate attention. This paper explores the integration of drones or Unmanned Aerial Vehicles (UAV's) into infrastructure monitoring and post-disaster assessment. Through reviewing some of the recent disasters, effectiveness of utilizing UAV's in different stages of disaster life cycle is demonstrated and needed steps for successful integration of UAV's in infrastructure monitoring, hazard mitigation and post-incident assessment applications are discussed. In addition, some of the challenges associated with implementing UAV's in disaster monitoring, together with research needs to overcome associated knowledge gaps, is presented.

Purpose - The primary purpose of this study is to verify whether the target set out by the International Maritime Organization (IMO) for reducing carbon emissions from ships can be achieved by quantitatively analyzing the trends in technological advances of fuel oil consumption in the container shipping market. To achieve this purpose, several scenarios are designed considering various options such as eco-friendly fuels, low-speed operation, and the growth in ship size. Design/methodology - The vessel size and speed used in prior studies are utilized to estimate the fuel oil consumption of container ships and the pace of technological progress and Energy Efficiency Design Index (EEDI) regulations are added. A database of 5,260 container ships, as of 2019, is used for multiple linear regression and quantile regression analyses. Findings - The fuel oil consumption of vessels is predominantly affected by their speed, followed by their size, and the annual technological progress is estimated to be 0.57%. As the quantile increases, the influence of ship size and pace of technological progress increases, while the influence of speed and coefficient of EEDI variables decreases. Originality/value - The conservative estimation of carbon emission drawn by a quantitative analysis of the technological progress concerning the fuel efficiency of container vessels shows that it is not possible to achieve IMO targets. Therefore, innovative efforts beyond the current scope of technological progress are required.

This paper aims to reach the perceptions, ideas and intentions of the higher education adolescences on the effects of technological innovations over interrelation/communication between individuals. While advances in technology commonly works for the welfare and benefit of humankind, paradoxically in some instances could have negative outcomes on interrelations among individuals, minimizing face-to-face communication. The perceptions, so ideas of the individuals on the matter could differ depending on their age, gender, race and the culture beyond their relative intimacy and closeness to ICT tools. In order to penetrate the basic initiatives leading the perceptions of adolescents on the effects of technological improvements on human interrelations/ communication, a survey is conducted with 157 students in high education consisting of Asian, African, Cypriot, Turkish nationals. Results indicate that participants use technological tools for communication which lessens their face-to-face interaction. However they prefer social media more than face-to-face communication during conflict or undesirable situations.

In recent innovation trends, one notable feature is the merging and overlapping of technologies: in other words, technological convergence. A key technological convergence is the fusion of biotechnology (BT) and information technology (IT). Major IT advances have led to innovative devices that allow us to advance BT. However, the lack of data on IT-BT convergence is a major impediment: relatively little research has analyzed the inter-disciplinary relationship of different industries. We propose a systematic approach to analyzing the technological convergence of BT and IT. Patent analysis, including citation and co-classification analyses, was adopted as a main method to measure the convergence intensity and coverage, and two portfolio matrices were developed to manage the technological convergence. The contribution of this paper is that it provides practical evidences for IT-BT convergence, based on quantitative data and systematic processes. This has managerial implications for each sector of IT and BT.
