While the 4^th Industrial Revolution (4^th IR) is actively being discussed in Korea, the core and common point is that in the era of the 4^th IR, computer networking is becoming more common due to the generalization of ICT(Information and Communication Technology). There may be a variety of factors that have allowed ICT to occupy a core position in the 4^th IR, but the most important may be the position of ICT as a foundation technology. ICT has important technical value in itself, but when it is converged with other technology or industry, or when it acts as a foundation technology of such technology or industry, it greatly improves the value of existing technology or industry. Thus, this paper focused on ICT, the core technology of the 4^th IR, to examine the past, present and future of ICT-related R&D and ICT-based convergence industries. In other words, the purpose of this study is to identify which areas ICT has been actively researched from past to present and what changes have been made in such areas.

'4th Industrial Revolution' is accelerating as a core part of creating new growth engines and enhancing competitiveness of businesses. The fourth industrial revolution means the transformation of society and industries that are brought by IoT (Internet of Things), big data analysis, AI (Artificial Intelligence), and robot technology. Information and Communication Technology (ICT), which is a major factor, is affecting production and manufacturing systems and as ICT technologies become more advanced, intelligent information technology is generally utilized in all areas of society, leading to hyper-connected society where new values are created and developed. ICT technology is not just about connecting devices and systems and making smart, it is about constantly converging and harmonizing new technologies in a number of fields and driving innovation and change. It is no exception to the agro-fisheries trade. In particular, ICT technology is applied to the agricultural sector, reducing labor, providing optimal environment for crops, and increasing productivity. Due to the nature of agriculture, which is a labor-intensive industry, it is predicted that the ripple effects of ICT technologies will become bigger. We are expected to use the Smart Concentration using ICT convergence technology as a useful resource for changing smart farms, and to help develop new service markets.

Water quality is crucial for human health and the environment. Accurate measurement of the quantity of organic carbon in water is essential for water quality evaluation, identification of water pollution sources, and appropriate implementation of water treatment measures. Total organic carbon (TOC) analysis is an important tool for this purpose. Although other methods, such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD) are also used to measure organic carbon in water, they have limitations that make TOC analysis a more favorable option in certain situations. For example, COD requires the use of toxic chemicals, and BOD is time-consuming and can produce inconsistent and unreliable results. In contrast, TOC analysis is rapid and reliable, providing accurate measurements of organic carbon content in water. However, common methods for TOC analysis can be complex and energy-intensive because of the use of high-temperature heaters for liquid-to-gas phase transitions and the use of acid, which present safety risks. This study focuses on a TOC analysis method using TiO₂ photocatalysis, which has several advantages over conventional TOC analysis methods, including its low cost and easy maintenance. For TiO₂, rutile and anatase powders are mixed with an inorganic binder and spray-coated onto a glass fiber substrate. The TiO₂ powder and inorganic binder solutions are adjusted to optimize the photocatalytic reaction performance. The TiO₂ photocatalysis method is a simple and low-power approach to TOC analysis, making it a promising alternative to commonly used TOC analysis methods. This study aims to contribute to the development of more efficient and cost-effective approaches for water quality analysis and management by exploring the effectiveness and reliability of the developed equipment.

Automatic emotion recognition based on facial cues, such as facial action units (AUs), has received huge attention in the last decade due to its wide variety of applications. Current computer-based automated two-phase facial emotion recognition procedures first detect AUs from input images and then infer target emotions from the detected AUs. However, more robust AU detection and AU-to-emotion mapping methods are required to deal with the error accumulation problem inherent in the multiphase scheme. Motivated by our key observation that a single AU detector does not perform equally well for all AUs, we propose a novel two-phase facial emotion recognition framework, where the presence of AUs is detected by group decisions of multiple AU detectors and a target emotion is inferred from the combined AU detection decisions. Our emotion recognition framework consists of three major components - multiple AU detection, AU detection fusion, and AU-to-emotion mapping. The experimental results on two real-world face databases demonstrate an improved performance over the previous two-phase method using a single AU detector in terms of both AU detection accuracy and correct emotion recognition rate.

In this study, we prepared epoxidized poly ethylene-ter-1-decene-ter-divinylbenzene (Epo-PEHV) as a reactive compatibilizer to prevent phase separation phenomenon which occurs upon blending polypropylene (PP) and ethylene-vinyl alcohol copolymer (EVOH). Firstly, PEHV was prepared under high catalyst activity according to content of catalyst and cocatalyst. After then, we modified vinyl group of the terpolymer with epoxy group. We observed that the terpolymer was successfully epoxidized by 1H-NMR and FT-IR analysis. The Epo-PEHV was added by 2, 5, 10% in PP/EVOH blends. The morphologies and mechanical properties of PP/Epo-PEHV/EVOH blends were analyzed by SEM and UTM, respectively. Epo-PEHV enhanced the interfacial adhesion of PP and EVOH blends.

This study presents one man-portable, hazardous gas detecting and capturing robot. The robot can be fit in the trunk of a sedan car. Its weight is less than 20 kg. A dedicated gas intake mechanism is proposed for the robot. The robot can detect and capture gases at a height of 2 m above the ground, although the height of the robot is about 0.2 m. The performance of the gas intake mechanism is verified through computational fluid dynamics (CFD) analysis and experiments. Its gas detecting signals were acquired by serial communication and processed in Robot Operating System (ROS) based control software. The proposed robot can successfully move on rough terrains such as stairs, sand roads, and rock roads.

본 연구는 기술지식의 융 복합화로 인해 특정 산업에서 다른 부분으로 영역이 확장되는 양상을 확인하는 것으로, 비수도권 농촌 지역인 전라북도 순창군의 장류산업을 중심으로 분석하였다. 이를 위해 특허출원 자료를 이용하여 기술융합분석과 지식네트워크분석을 실시하였다. 분석 결과, 국내 장류산업은 단순 식품, 식료품 제조 기술에서 기계 기기나 의약품 및 화장품 관련 기술로 폭넓게 융합이 이루어지는 반면 순창군의 장류산업은 발효미생물 관련 기술 방향으로 특화되고 있다. 이는 산업 전체의 융합 경향을 따라 여러 기술 분야로 확장하기 보다는 순창이 갖는 지역자산과 인력에 맞추어 지역산업을 특화시킨 결과라고 판단된다. 순창군 장류산업의 지식네트워크는 지방정부와 대학, 진흥원 등 공공부문이 주도적인 역할을 하고 있고, 최근 조합법인 형태의 출원자와 공공부문의 협력을 통해 지역 내 기술 공유와 확산을 가져오는 것으로 나타났다.

본 연구는 국가과학기술연구회에서 운영하는 융합연구사업과 출연(연)에서 수행하는 일반 수탁연구사업의 연구 성과에 대해 효율성을 비교 분석하였으며 이를 통해 융합연구 운영 및 관리의 효율성 제고 방안을 제시하고자 하였다. 연구데이터는 정보공개청구를 통해 21개 정부출연연구기관을 대상으로 수집되었고 효율성 평가를 위해 DEA 분석을 실행하였다. 분석결과 융합연구의 SCI 논문은 높은 효율성을 나타냈고 특허등록과 기술이전 부문은 일반연구사업이 높은 효율성을 나타냈다. 이는 선도 및 원천기술 확보를 위한 융합연구사업이 당초 목적에서 부합되는 높은 효율성을 나타내고 있으나, 이로 인해 파생되는 기술의 활용도 면에서는 기업들의 참여 부족 등으로 그 성과가 낮은바, 융합연구 결과의 실용화를 위해 보다 많은 기업의 참여와 기회가 필요함을 시사한다. 본 연구는 융합연구사업 성과의 효율성 분석을 통해 제한된 인력 및 연구비용의 합리적인 투자를 위한 R&D 기획 및 정책에 활용 지침을 제공하였다. 또한, 융합연구 관리 방안으로서 융합연구의 대상 기술 유형에 따라 효율성 파악에 관한 미래 연구를 제안하고 있다.
