  • Oil spills caused by the accidents have been occurred from house and factory waste, grounded tanker, the rupture of storage tank and oil pipelines, the deterioration of various industrial facilities, etc. Many oil spills result in contamination of shorelines and workplace. Fire and explosion may happen from these spills. There are several technologies used for clean-up application, which include use of oil dispersing agents, absorbents, solidifiers, booms and skimmers by physical, chemical, and biological methods. Methods for oil spill clean-up operation are classified into the absorption type, gel type and self-swelling type. Porous materials with oil absorptive properties are classified into micropore, mesopore, and macropore depending on their pore sizes. Recently, new porous materials with smaller size have been developed, but the selective oil absorption in water-in-oil interface demonstrates the macro pore size. In this study oil absorption effects were evaluated using the organic porous materials with a complex function of gel type and swelling type. Samples were subjected to analysis by FT-IR spectroscopy and were characterized in terms of gel formation and morphologies. Oil sorption capacity, pressure retention force and gel strength were also measured. From these results, the physicochemical reactivity before and after gelation was verified and the industrial applications of clean-up operation were suggested.

  • There has been a pronounced increase in research and development (R&D) expenditure in Singapore over the last two decades, with government spending accounting for a sizeable share. This increase has been spurred by public policy emphasis on research and innovation as engines of economic growth. This paper analyses the impact of R&D on economic performance in Singapore from 1978 to 2012 through the use of time series analysis. The Cobb-Douglas based analysis shows a long-run equilibrium relationship between Total Factor Productivity (TFP) and R&D investments. We found that the short-run productivity of R&D in Singapore is comparable to smaller advanced economies in the Organisation for Economic Co-operation and Development (OECD). However, in terms of long-run R&D productivity, Singapore lags slightly behind the smaller OECD nations and far behind the G7 countries. This suggests leakage of value capture and low absorptive capacity in local firms. Possibility of productivity improvements induced by policy changes in the 1990s was considered, but no evidence of significant structural breaks was found. Lastly, Granger causality analysis reveals that public sector R&D augments private sector R&D capital, thus playing an important role in generating externalities and spillover effects. Policy implications and lessons for other middle-income countries are discussed.

  • Voltage and frequency stability issues occur in existing centralized power system due to the high penetration of renewable energy sources, which decrease grid absorptive capacity of them. The grid-connected inverter that mimics synchronous generator characteristics with inertia characteristic is beneficial to electric power system stability. This paper proposed a novel three-phase four-wire grid-connected inverter with an independent neutral line module that mimics synchronous generators. A mathematical model of the synchronous generator and operation principles of the synchronverter are introduced. The main circuit and control parameters design procedures are also provided in detail. A 10 kW prototype is built and tested for further verification. The primary frequency modulation and primary voltage regulation characteristics of the synchronous generator are emulated and automatically adjusted by the proposed circuit, which helps to supports the grid.

  • This study aims to investigate the relationship between foreign direct investment (FDI) and economic growth at the provincial level by using time-series data in Binh Dinh from 1997 to 2019. We applied the quantitative approaches Vector Autoregression (VAR) and Autoregressive Distributed Lags (ARDL) in the model, which includes economic growth, real foreign direct investment capital, ratio of trained workers, and infrastructure. The results show that all these variables are stationary at the first difference. In ARDL analysis, we found that the economic growth positively affects FDI attraction. However, there is no evidence of the effect of FDI on economic growth in the condition of low capital implemented. Moreover, findings also show that the impact of FDI on economic growth is influenced by two factors: infrastructure and human capital. The lack of human capital, which is trained personnel and infrastructure, is the main barrier hindering and inhibiting FDI's contribution to local economic growth. In order to improve the efficiency of FDI on economic growth in the future, it is suggested that the Binh Dinh government should have proper policies in terms of the infrastructure, the human capital investment. They would allow Binh Dinh to enhance the capital absorptive capacity and capital efficiency.

  • Providing services using kiosks is actively carried out between suppliers and consumers. These service processes have recently begun to play a dominant role in transactions. However, previous self-service technology (SST) studies or kiosks have not fully reflected the changing environment surrounding these different technologies. To cover the updated business environments, we combined qualitative and quantitative research methods. Through qualitative research and a review of previous studies, the variables emphasized as motivations and constraints for kiosks use and those that can be newly illuminated were selected for this study. We then applied the variables to the research model to assess their influence. In terms of the motivations for using kiosks, the results suggest that perceived usefulness and compatibility as service quality, forced use, and perceived service providers' efficiency as provider polices, absorptive capacity, and habit as an individual characteristic and social influence as a subjective norm have a significant effect on the attitude toward kiosks. In terms of constraints, difficult to use and need for interaction predicts the attitude toward kiosks. Attitude toward kiosks, perceived behavioral control, and social influence are directly related to the intention to use kiosks. Lastly, intention to use kiosks plays a significant role as an antecedent of revisit intention. Using these empirical results, we propose both academic and practical implications for future kiosks use.

  • The information and communication technology (ICT) value creation process is inherently unobservable. In addition to the direct effect of ICT on productivity, some information or knowledge can create value through other knowledge activities. In this paper, we study the impact of ICT on productivity through R&D. We tested the mediating effect of R&D between ICT and productivity using panel data from 47 US industries from 1987 to 2013 from the Bureau of Labor Statistics. The results show that R&D partially mediates ICT and productivity. That is, ICT directly increases productivity, and some of its effects can be realized through R&D. Recipients who acquire knowledge through ICT have to interpret codified ideas and apply them to practice. The increased absorptive capacity that can be developed through R&D improves interpretation ability, allowing employees to share more complex ideas. Thus, ICT helps people to effectively communicate, but some information and knowledge can be realized and applied through R&D knowledge activities. This is the first study empirically examining the process of ICT value creation through R&D. It also provides practical guidelines for knowledge management, such as making decisions about ICT and R&D investments that are better done concurrently rather than individually to maximize their impact on productivity.

  • 지식 네트워크는 지역의 경제적 성과와 경쟁력을 확보하는데 중요한 요소로 간주된다. 또한 지식을 흡수할 수 있는 능력이 높은 연구기관들은 지역적 요인에 상관없이 글로벌 지식 네트워크를 형성하려는 경향이 강하며, 그렇지 않은 기관들은 지역적 요인에 많은 영향을 받는다. 본 연구에서는 한국의 지역을 중심으로 지식 흡수능력이 낮은 기관일수록 지식 네트워크의 지리적 요인에 얼마나 많은 영향을 받는지에 대해 검증하였다. 그 결과, 지식 흡수능력이 높은 기관일수록 국제 공동연구를 추진하고 있는 것으로 나타났으며 수도권을 제외한 다른 지역에서는 거점 대학을 중심으로 연구가 진행되고 있는 것으로 나타났다. 즉, 과학기술이 발전된 지역은 더 이상 반드시 지역적인 요소가 중요 요인이 아니라는 것을 의미한다. 이러한 연구결과는 상당부분 선행이론들의 논의와 부합하는 것으로 나타났다. 또한 사전연구에 대해 한국 지역을 중심으로 사례연구를 진행하여 이를 검증하였다는 점에서 연구의 가치가 있다.

  • 본 연구는 BtoB 기업 간 거래에서 형성된 사회적 자본(social capital)이 기업성과에 미치는 영향을 지식흡수역량의 매개적 조절효과를 중심으로 연구모형을 검증하였다. 즉, 사회적 자본의 각각의 차원이 기업성과에 어떠한 영향을 미치는지를 검증하였다. 기존선행연구에서 제시하지 않은 사회적 자본의 각 차원간의 관계를 검증함으로써 사회적 자본 중 어떠한 요소가 기업성과에 영향을 미치는지를 확인하였다. 또한 지식흡수능력에 따라 기업성과에 미치는 영향에 대해 다양한 방법으로 분석하여 제시하였다. 연구결과를 요약하면 다음과 같다. 첫 번째, 사회적 자본을 3가지 차원으로 구분하였다. 즉, 구조적 차원, 관계적 차원 그리고 인지적 차원으로 구분하여 각 구성요소간의 관계를 검증하였다. 먼저 구조적 차원이 관계적 차원에 영향을 미쳤으며, 관계적 차원이 인지적 차원에 긍정적인 영향을 미치는 것으로 나타났으며 마지막으로 구조적 차원 또한 인지적 차원에 영향을 미치는 것으로 나타났다. 이는 선행연구에서 한계점으로 지적되었던 것을 검증했다는 것에 의미가 있다. 두 번째, 사회적 자본의 각각의 구성요소들이 지식흡수역량에 긍정적인 영향을 미치는 것으로 나타났다. 마지막으로 지식흡수역량이 기업성과에 긍정적인 영향을 미치는 것으로 나타났으며 지식흡수역량의 중요성을 확인한 결과 사회적 자본과 기업성과 사이에서의 매개된 조절 효과도 있음을 확인하였다. BtoB 거래에서 축적된 사회적 자본을 어느 정도 흡수하는가에 따라 두 기업의 성과는 분명 다를 수 있음을 의미한다.
