ICT분야는 지난 20여 년간 산업촉진 및 효율성 제고 측면에서 강력한 정부주도로 정보화를 추진하여 많은 성과를 거두었고, 현재에도 국내 산업을 견인하고 있다. ICT분야가 주목을 받는 만큼 특허 분쟁도 심화되었고 ICT분야의 특허 확보도 매우 중요해졌다. 특허는 기업의 기술혁신의 수준을 평가하는 대표적인 척도로 인식되어 기업의 성과를 측정하는데 많이 활용되고 있다. 그러나 기존의 연구는 특허의 양(量)적인 성장이 기업 경영성과에 영향을 미치는가에 대한 연구가 대부분으로 질(質)적 수준에 대한 연구는 미진하였다. 본 연구에서는 국가산업을 기인하는 ICT 기업이 보유한 특허의 질적 수준이 경영성과에 영향을 미치는지 분석하였다. 즉, 특허의 질적 수준을 측정하는 척도인 기술혁신 활동 집중도가 기업의 성장성과 수익성에 영향을 미치는지 분석하였다. 연구결과, 기술혁신 활동 집중도의 현시기술우위 지수(RTA)와 집중률 지수(CRn)는 기업의 성장성과 수익성에 유의한 영향을 미치는 것으로 나타났다. 본 연구를 통하여 ICT분야에서 특허의 질적 수준이 높을수록 기업의 성장성 및 수익성에 정(+)의 영향을 미칠 수 있다는 것을 검증한 바, 특허의 질적 수준 연구가 미미한 상황에서 차후 연구에 대한 새로운 출발점을 제시할 수 있을 것으로 기대된다.

Due to social distancing caused by COVID 19, music concerts have not been allowed at home and abroad, and it is not known when overseas concerts will be able to resume unless the pandemics calm down, even if they are available. Meanwhile, people consume much more content through online services such as Netflix and YouTube than before. Under these circumstances, the music industry expects the virtual livestreamed performance to restore sluggish live performances again and bring about a digital renaissance. It also leads to the issue of reestablishing a copyright system regarding a livestreamed performance and of preparing a new rate of royalty standards for the use of works in OTT. In addition, a multi-territorial licensing of r ights in musical works is necessary to resolve copyright issues efficiently by applying the same term s to all countries from where the audience comes. In this paper, I examine the legal nature and the decision of copyright fees of performances as an integral part of the music industry.

X-ray astronomy deals with measurements of the electromagnetic radiation in the energy range of $E\~0.1-100 keV (\lambda\~0.12-120{\AA})$. The wavelength of X-ray is comparable to the size of atoms, so that the photons in the X-ray range are usually produced and absorbed by the atomic processes. Since the launch of the first X-ray astronomy satellite 'Uhuru' in 1970, technological advances in a launch capability and a detection capability make X-ray astronomy one of the most rapidly evolving fields of astronomical research. Particularly, a spectral resolving power $E/{\Delta}E$ has been increased by an order of 2 - 3 (in the energy range of 0.1 - 10 keV) during the past 30years. In this paper, I briefly review a developing process of the resolving power and spectroscopic techniques. Then I describe important emission/absorption lines in X-ray astronomy, as well as diagnostics of gas property with line parameters.

In order to utilize unsorted ONP, which contains leaflets (printed coated papers), as a raw material to produce pulp mold, optimum conditions for repulping were investigated with the pilot Helico pulper at Centre Technique du Paper (CTP), France. Two major process factors were focused: repulping concentration and rotor speed. Repulping at a higher concentration showed more rapid defibering kinetics. Increasing the rotational speed of rotor at the optimum repulping concentration accelerated the defibering kinetics while it also led to higher fines generation and faster decrease in drainage property of the produced pulp. Hence, an alternative way was suggested: starting repulping at a conventional rotor speed and then accelerating the rotor speed for the last minute(s) of repulping.

The explosion in creation and utilization of IP including Patent since 1980s has been regarded as typical trend affecting the environment for technological innovation. Korea also has shown massive creation of IP. These stimulate the focused interest on the effectiveness of IP for protecting the innovation output. We try to analyze the determinants of this effectiveness in Korean manufacturing sector in terms of the charactenstics of firm's innovation strategy. It is shown that, for protection for product innovation, as being larger, and as having made innovation, the IP protection is regarded as effective, and firms making cooperative R&D have a higher possibility of using IP protection. And larger firms give a higher recognition to effectiveness of IP protection irrespective of the types of innovation such as product innovation and process innovation.

This paper presents a new ZVS single phase bridgeless (Power Factor Correction) PFC, using an active clamp to achieve zero-voltage-switching for all main switches and diodes. Since the presented PFC uses a bridgeless rectifier, most of the time, only two semiconductor components are in the main current path, instead of three in conventional single-switch configurations. This property significantly reduces the conduction losses,. Moreover, zero voltage switching removes switching loss of all main switches and diodes. Also, auxiliary switch turns on zero current condition. The presented converter needs just a simple non-isolated gate drive circuitry to drive all switches. The eight stages of each switching period and the design considerations and a control strategy are explained. Finally, the converter operation is verified by simulation and experimental results.
