In this study, project information of government-funded research institute in the food field was collected and analyzed to systematically identify the factors affecting the process of transferring technological achievements of public research institute to the private sector. This study hypothesized that human resources, financial resources, and technological characteristics as input factors of R&D projects affect output factors, such as research papers or patents produced by R&D projects. Moreover, these outputs would serve as drivers of the technology transfer as one of the R&D outcomes. Linear Regression Analysis and Poisson Regression Analysis were conducted to empirically and sequentially investigate the relationship between input factors and output and outcome of R&D projects and the results are as follows: First, the principle investigator's career and participating researcher's size as human resource factors have an influence on both the number of SCI (science citation index) papers and patent registration. Second, the research duration and research expenses for the current year have an influence on the number of SCI papers and patent registrations, which are the main outputs of R&D projects. Third, the technology life cycle affects the number of SCI papers and patent registrations. Lastly, the higher the number of SCI papers and patent registrations, the more it affected the number of technology transfers and the amount of technology transfer contract.

Seaports play a vital role in the economic development of countries, especially for countries having long coastlines such as Vietnam Seaport industry in Vietnam has witnessed an impressive development in recent years. The national cargo throughput in the period 2013-2017 achieved a compounded annual growth rate (CAGR) of 11.8%/year, higher than that of the world (5.1%). However, the differences in planning policies and infrastructure systems has led to the differences in port performance efficiency of regional ports. Therefore, it is necessary to have a general and accurate view of the picture of Vietnam's seaport. The objective of this study was to analyze the relative efficiencies of 26 Vietnam container terminals using traditional output-oriented CCR and BCC DEA model. Malmquist P roductivity Index (MP I) was also applied to evaluate changes in container terminals productivity over time.

The purpose of this paper is to explore how the Confucius Institute Chinese international promotion could better promote the development of China's foreign trade, by analyzing the distribution of the Confucius Institute worldwide, based on the theory of language economics, using SWOT analysis to analyze the advantages and disadvantages of the internal environment, opportunities and challenges of the external environment of Chinese international promotion of Confucius Institute. The following findings were gathered: as a language teaching institution and information exchange platform, Confucius Institute has the ability to share trade information and increase trade opportunities; to improve cultural identity and reduce transaction costs; to promote cultural communication and integration, and drive the development of related industries. The internal disadvantages were mainly reflected in the mismatch between the global regional distribution structure of Confucius Institutes, and the economic and trade structure, such as, the asymmetry between language, culture output, and demand. In addition, the management mechanism was not perfect. External opportunities were mainly new opportunities brought by economic globalization, cultural diversity, and the development of the Belt and Road initiative. External challenges were mainly influenced by the China threat theory and the fierce cultural competition among countries. The corresponding countermeasures were put forward based on the advantages of the platform and grasping the external opportunities: improving the quality of operation and speeding up the localization process; respecting cultural differences and realizing cultural common learning; seeking multilateral cooperation and enhancing the capacity for independent development.

The research is also intended to contribute by supplying the basic data, to the development of other programs in relevant areas where similar nursing information system is required. This research used System Development Life Cycle method. Results from the study were as follows : The scope of Information System in nursing practice were based on a wide range of mateials as charts at four hospitals in Pusan that cover the nursing period of spinal cord injury patients from admission to discharge and other sources of reference, the research is done for nursing diagnosis, nursing history, admission and discharge education, and the performing of doctor's order, which were divided into a subsystem that consisted of help, Patient Management, Performing of Docter's Order, and Basic Data Management and then these was analysed systematically using Hierachy Plus Input Process Output, necessary information, data flow diagram, and conceptual designs were developed for chosem system. Furthemore, the system has been programed by a conceptual design that includes the objects of the program and the origins of the sources. The oder to make sure of the proper function, the computer program was actually applied to a nursing practice that had been developed for a hypothetical situation through the two nurses who were in charge of spinal cord injury patients after they were trained to understand the structure and the contents of computer program about the nursing practice from using the computer program developed. Also, the compensatory strategy has been worked out against any problems to arise. It is expected that this kind of nursing practice information system to be used for the spinal cord injury patients that has been developed through the processes shown above will increase the satisfaction for both patients and nurses by enabling them to give more professional advice and service to the development of more information systems for many hospitals.

In this paper, phase noise analysis result for 2.4 GHz PLL(phase locked loop) using SPD(sample phase detector) is proposed. It can be used for high performance frequency synthesizer's LO(local oscillator) to extend output frequency range or for LO of offset PLL to reduce a division rate or for clock signal of DDS(direct digital synthesizer). Before manufacturing, theoretical estimation of PLL's phase noise performance should be performed. In order to calculate phase noise of PLL using SPD, Leeson model is used for modeling phase noise of VCO(voltage controlled oscillator) and OCXO(ovened crystal oscillator). After theoretically analyzing phase noise of PLL, optimized loop filter bandwidth was determined. And then, phase noise of designed loop filter was calculated to find suitable OP-Amp. Also, the calculated result of phase noise was compared with the measured one. The measured phase noise of PLL was -130 dBc/Hz @ 10 kHz.

본 연구는 중소 벤처기업이 보유하고 있는 자원뿐만 아니라 자원을 획득하기 위한 노력(intent to access resources from others)이 자원이 부족한 중소벤처기업의 성장 및 생존에 매우 중요한 영향을 미치고 있음을 정량적 자료의 분석과 사례연구를 통해서 확인하였다. 특히 중소 벤처기업의 자원에서 매우 중요한 역할을 하는 기술자원의 확보 (Itami, 1987)가 어떻게 기업의 성장 및 생존에 영향을 미치는지를 살펴보았으며, 세계화의 관점(international perspective)에서는 세계화를 통한 시장확대를 한 기업들이 기업에게 필요한 독특한 자원과 능력을 확보하게 되고, 이 확보된 자원과 능력이 기업의 생존 및 성장에 영향을 미침을 확인하였다. 본 연구에서는 중소 벤처기업이 성장하고 생존하기 위해서는 자원의 보유뿐만이 아니라 부존 자원을 확보하기 위한 노력 즉, 전략적 제휴, M&A 등을 통한 자원획득 전략과 세계화를 통한 시장 확대가 성장 및 생존에 필수조건임을 알 수 있었다. 그러나 본 연구의 인터뷰에 참여한 25개 기업 중 성공적인 세계화를 이룬 경우는 30% 미만이었으며, 자원확보를 위한 전략적 제휴 및 M&A, 대기업과의 공동 연구개발 등을 진행, 세계화 추진에 여러 가지 애로사항이 있는 것으로 파악되었다. 공동개발, 제휴 등의 협력을 바탕으로 한 성공적 세계시장으로의 진출을 해결할 수 있는 대안으로 본 연구자들은 유기적 협력체 형성 즉, 소벤처 생태계의 조성 및 활성화가 필요함을 강조하였다. 최근 글로벌 시장에서의 경쟁은 개별기업 간 경쟁에서 기업 네트워크 간 경쟁으로 변화되고 있다. 이러한 상황에서 개별 벤처기업의 단독 해외시장의 진출은 매우 위험한 전략이라고 할 수 있으며 지속성장을 위해서는 선도기업과 초기 벤처기업 간 상생 협력 체계를 구축하여 해외시장에 동반 진출해야 할 필요가 있다.
