This study analyzes the effects of the absorptive capacity on the technology innovation and commercialization capacities and the management performance. Based on previous studies, the absorptive capacity is sub-classified into the exploratory absorptive capacity and the exploitative absorptive capacity, which are set as independent variables, to analyze their effects on the technology innovation and commercialization capacities. In short, the absorptive capacity has positive effects on the technology innovation and commercialization capacities. In addition, the technology innovation capacity and the technology commercialization capacity have positive effects on the management performance. The findings confirm that the absorptive capacity is an important factor impacting on the corporate innovation, and suggest that businesses should recognize the importance of the absorptive capacity as a guideline for developing their strategies for technological innovation.

이중효용 흡수냉동기의 고효율화 방안과 당사(한국 캐리어)에서 개발한 흡수식 냉동기를 소개 하고자 한다. 흡수냉동기는 1777년 영국의 NAIRNE에 의해 흡수냉동기 이론을 발표한 이후 1945년 미국 CARRIER사가 냉매로서 물, 흡수제로서 리튬브로마이드(LiBr)를 이용한 일중 효용 흡수냉동기가 세계 최초로 상용화되면서 공조용 및 산업용 냉방기기로서 보급되기 시작하였다. 이러한 흡수식 기술은 일본에서 이중효용 흡수냉동기 및 냉온수기를 개발하면서 공조용 및 산업용 냉. 난방기기로서 널리 보급되기 시작하였으며, 최근에는 고 효율 이중효용 흡수냉동기 및 냉온수기(COP 1.2-l.3)를 개발하여 제작. 판매하고 있으며 또한 삼중효용 흡수냉온수기(COP 1.6)를 개발하고 있다. 그리고 세계 흡수냉동기 시장은 일본 및 중국을 중심으로 고 효율 흡수냉동기 시장으로 재편되고 있다. 그러나, 우리나라에는 아직 일본기술에 의존한 표준 COP 이중효용 흡수냉동기 및 냉온수기(COP 1.01)를 제작 판매하고 있는 실정이다. 따라서 본 고에서는 이중효용 흡수냉동기의 고효율화 방안과 당사(한국 캐리어)에서 개발한 흡수식 냉동기를 소개하고자 한다.

본 논문에서는 지구온난화의 주요원인 중의 하나인 이산화탄소를 포집하기 위한 새로운 흡수제를 연구하였다. 액상 흡수법에서 가장 중요한 핵심 기술요소는 성능과 경제성면에서 우수한 흡수제를 개발하는 것이다. 흡수평형장치인 VLE(Vapor-Liquid Equilibrium)장치를 사용하여 신규흡수제의 이산화탄소 흡수능을 평가하고 특성을 알아봄으로써 신 흡수제를 개발하고자 하였다. 기존 아민흡수제인 MEA(monoethanolamine), DEA(diethanolamine)와 비교한 결과 아미노산염 흡수제의 경우 MEA (1.108), DEA (1.105)의 이산화탄소 흡수능보다 0.15～0.2 (mol $CO_2$/mol absorbent) 더 높은 흡수능과 2.5～3배 더 빠른 겉보기 속도를 나타내는 것을 확인하였다. 본 연구를 통하여 개발된 아미노산염 흡수제가 경제적인 이산화탄소 포집공정을 구현할 수 있는 가능성을 확인하였다.

삼중효용 흡수식 냉동기의 기본 원리, 사이를 구성 방법 및 특성, 제품 개발을 위한 핵심 기술에 대하여 알아본다. 현재 널리 사용되는 흡수식 냉동기는 대부분이 이중효용(double effect) 기기이며 그 동안의 많은 기술 축척과 연구개발의 결과, 성능이 향상되어 최근 일본에서 출시되는 신제품은 냉방 COP가 약 1.3을 넘어서고 있다. 그러나 이중효용 흡수식 냉동기로서는 도달 가능한 COP에 한계가 있기 때문에 2-3년 전부터 삼중효용 흡수식 냉동기에 대한 연구가 일본 등에서 활발히 진행되고 있다.(중략)

Amid rapid changes in technological innovation due to the influence of the 4th Industrial Revolution and COVID-19, research related to absorption capacity and patent activities to promote technological innovation of Korean technology start-ups is important in this uncertain environment. This study aims to examine the effects on entrepreneurial performance and patent activities by reconstructing absorptive capacity, an organizational capability, for technology-based startups in fields such as BT and ICT with less than seven years of establishment, distinguishing between potential absorptive capacity and realized absorptive capacity. The study also seeks to develop a theoretical research model. To accomplish this, data was collected from managerial executives, including CEOs of 215 technology startups. The following hypotheses were tested: Firstly, potential absorptive capacity had a significant impact on patent activities, while realized absorptive capacity did not. Secondly, potential absorptive capacity had a significant impact on technological performance, while realized absorptive capacity did not. Thirdly, both potential and realized absorptive capacity had a significant impact on financial and non-financial performance. Fourthly, patent activities indirectly influenced potential absorptive capacity and technological performance, but did not affect realized absorptive capacity. Fifthly, patent activities indirectly influenced potential absorptive capacity and financial performance, but did not affect realized absorptive capacity. Lastly, patent activities indirectly influenced potential absorptive capacity and non-financial performance, but did not affect realized absorptive capacity. The practical significance of this study lies in providing useful guidelines for building the core capabilities of organizations through absorptive capacity and patent activities. Furthermore, it is expected that startups that have not recognized the formation process of absorptive capacity for patent activities will perceive the formation mechanism of absorptive capability anew and show considerable interest in future potential and realized absorptive capacity as part of their management strategies. This is anticipated to play an important role in adapting to rapidly changing technological advancements, the startup ecosystem, and securing sustainable competitive advantages.

This paper addresses recent status and trends of carbon dioxide capture technologies using dry sorbents in the flue gas. The advantages of dry sorbent $CO_2$ capture technology are broader operating temperature range, less energy loss, less waste water, less corrosion problem, and natural properties of solid wastes. Recently, U.S.A. and Korea have been developing processes capturing $CO_2$ from real coal flue gas as well as sorbents improving sorption capacity to decrease total $CO_2$ capture cost. New class of dry sorbents have been developed such as chemisorbents with alkali metals of which material cost is low, amines physically adsorbed on silica supports, amines covalently tethered to the silica support, carbon-supported amines, polymer-supported amines, amine-containing solid organic resins and metal-organic framework. The breakthrough is needed in the materials on dry sorbents to decrease capture cost.

The research object is stepwise process of absorptive capacity is important factor to get the successful result of technology commercialization training program. We analyze the relationship between absorptive capacity and educational performance with empirical study to the students who attended the technology commercialization training program. Results show that potential absorptive capacity has positive effect on realized absorptive capacity. Realized absorptive capacity also has the positive effect on educational performance. We conclude the successful technology commercialization training program is based on the stepwise process of absorptive capacity. That means technology commercialization training program will set up based on not functional but stepwise process. Further more, technology commercialization training program must be practical, focusing, interdisciplinary, and repetitive courses.

This paper aims at exploring the comparative impact of social networks and firm's absorptive capacity on the process of technological alliance such as technological alliance partner selection, governance structure and performance. Firms not only need to develop internal absorptive capacity but also need to cooperate with outside innovating entities. Increasing networks with other firms and enhancing firm's internal absorptive capacity become more and more important to enter into new market, increase network effects and develop firm's core capacities. In the view of firm's motivation for technological alliance such as expanding social networks and enhancing absorptive capacity, we develop hypotheses and tested comparative impact of those two constructs using 215 survey data of Korean venture companies. The results showed that absorptive capacity showed more impacts on the technological partner selection criteria than social networks. No impact was found between social network and alliance performance. Only absorptive capacity showed positive impact on the technological alliance success. Both constructs showed no impact on the choice of governance structure. In the conclusion section, we discussed the findings and implications of this study and directions for future studies.
