데이터 경제 시대에 있어서 웹 크롤링(crawling)의 법적 인식에 관한 연구

권세진,이정훈,이창무 한국산업보안연구학회 2021 한국산업보안연구 Vol.11 No.3

웹 크롤링은 빅데이터 시대에 있어서 필수불가결한 데이터 수집 방법론임에도 불구하고 그 법 적 기준이 불분명하고 관련 분쟁이 지속적으로 발생하고 있다는 점에서 부정적인 시각이 일부 존재한다. 그러나 웹 크롤링에 대한 소극적이고 부정적인 이해는 빅데이터 시대의 데이터 경제 촉진을 저해할 우려가 있다. 따라서 이 연구는 보다 객관적이고 중립적 입장에서 웹크롤링의 필 요성과 중요성에 대한 인식을 환기시키고자 웹 크롤링에 관한 특허기술, 선행 연구, 언론보도 등 을 분석하고, 관련 판례 및 법적 쟁점을 검토하였다. 분석 결과 웹 크롤링은 데이터 경제시대에 필수불가결한 기술이자 데이터 경쟁력의 원천이 되 며 몹시 다양한 분야에 활용되고 있으나, 지식재산권 침해 및 정보통신망 침입죄 등을 구성할 우 려가 존재한다는 점을 확인할 수 있었다. 그러나 웹 크롤링이 타인의 권리를 침해할 소지가 있더 라도, 데이터를 수집하여 새로운 가치를 창출하기 위해 유용하게 사용되는 웹 크롤링 기술의 특 성상 이에 대한 과도한 규제는 바람직하지 않다는 점을 도출하였다. 따라서 이 연구에서는 웹 크롤링을 데이터 경제시대의 원천이 되는 “자원 수집 기술”이자, “자 원 활용 기술”로서 원천기술에 해당하는 역할을 수행하는 것으로 이해하였다. 나아가 향후 TDM 면책 규정이 입법되고 데이터 활용 기반이 확충되는 경우라면 웹 크롤링의 역할은 더욱 중요해 질 것으로 전망하였다. 이에 따라 데이터 경제시대의 공정한 웹 크롤링 기반 조성의 방향성을 i) 법제도·정책 기반 개선 및 공정이용 가이드라인 마련, ii) 웹 크롤링 관련 대체적 분쟁해결 제도 활성화, iii) 상생과 협력의 웹 크롤링 생태계 마련으로서 공정거래법상 웹 크롤링 제한에 관한 규 율과 대·중소기업의 데이터 상생과 상호 활용 모델 발굴을 각 제안하였다. Web crawling is an indispensable data collection methodology in the era of big data. Nevertheless, the criteria for this are unclear, and related disputes continue to arise. This leads to a negative view of web crawling. However, a passive and negative understanding of web crawling raises concerns that it will hinder the promotion of the data economy in the era of big data. In order to raise awareness of the necessity and importance of web crawling from a more objective and neutral standpoint, this study analyzed patent technology, previous studies, and media reports on web crawling and reviewed related precedents and legal issues. As a result of the analysis, web crawling is an indispensable technology and a source of data competitiveness in the data economy era. At the same time, it was found that web crawling may constitute infringement of intellectual property rights and intrusion of information and networks. However, even if web crawling may infringe on the rights of others, excessive regulation of web crawling technology, which is usefully used to collect data and create new value, is not desirable. Therefore, in this study, web crawling was understood to play a role corresponding to the original technology as a “resource collection technology” and a “resource utilization technology” that is the source of the data economy era. Furthermore, it is predicted that the role of web crawling will become more important if the TDM exemption regulations are legislated and the basis for data utilization is expanded in the future. Accordingly, the direction of creating a fair web crawling base in the data economy era was suggested to 1) improve the legal and policy base and establish fair use guidelines, 2) revitalize alternative dispute resolution systems related to web crawling, and 3) establish web crawling ecosystems under the Fair Trade Act.

Development of an Ultra Stable High-Voltage Inverter Power Supply for the PAL-XFEL

권세진,고인수,서재학,오종석,장성덕,남궁원,손윤규 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.48 No.4

The Pohang Accelerator Laboratory (PAL) is persuading to construct a self-amplified spontaneous emission X-ray free-electron laser (SASE-XFEL) coherent X-rays. A bright and stable electron beam is essential for the PAL XFEL. If a reasonably stable SASE output is to be provided, an rms RF stability of 0.02 % rms is required for both the RF phase and the RF amplitude. This is a technologically challenging issue for the PAL XFEL. Inverter technology is to be applied to charge the pulse-forming network (PFN) of the new modulator. The new inverter system keeps an ultra-stable output voltage (0.01 %) and a high efficiency (>85 %) for output voltage of 50-kV. This paper presents the initial test results for the ultra-stable inverter power supply for the PAL XFEL.

Optimization of PVA/Oligosiloxane for High barrier property of food packaging.

권세진,김석조,석웅철,강주희,송호준,이상국 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

Food packaging yet represents a market of high potential for polymer materials. The continued quest for innovation in food and beverage packaging is mostly driven by consumer needs and demands influenced by changing global trends. In recent years, consumers have shown preferences for fresh, tasty, and minimally processed food products with a prolonged shelf life and new food packaging systems have been developed in response to these trends. Nanocomposite packages are predicted to make up a significant portion of the food packaging market in the near future. Polymer nanotechnology is actually developed mainly to improve barrier performance belonging to gases such as oxygen and carbon dioxide. It is proved also to enhance the barrier performance to ultraviolet rays, as well as to add strength, stiffness, dimensional stability, and high temperature durability. In this work, we have tried to improve of barrier property by using various contents of oligomer.

Characterization and properties of novel additive for highly conductive and non-visibility patterned PEDOT:PSS films

권세진,강주희,송호준,이상국 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.0

Optoelectronic devices, such as liquid crystal displays(LCDs), light-emitting diodes (LEDs), solar cells, touch panel displays, lasers, and detectors, have been attracting intense attention, due to their strong application in many aspects. In particular, Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) (PEDOT:PSS) with high transparency and superior mechanical flexibility is an excellent material as the transparent electrode. However, the pristine PEDOT:PSS films has a major problem of the low conductivity. In this work, we have tried to improve of low conductivity PEDOT:PSS and non-visibility patterned conductivity PEDOT:PSS by using novel materials with photo-reactive group. The conductivity of PEDOT:PSS films was significantly enhanced depended on the amount of novel materials and the photo-reactive difference of novel materials. The mechanism for the conductivity enhancement of PEDOT:PSS with novel materials is attributed to the phase separation of PSS chain from PEDOT:PSS.

중국의 상장기업 부실현황 및 정부의 기업개혁 논리 분석 : 특별처리기업(ST)·특별전환기업(PT)을 중심으로

권세진 고려대학교 평화연구소 2003 평화연구 Vol.11 No.1

본 논문은 중국의 부실 상장기업에 대한 연구를 통하여 정부와 상장기업간의 제도결합관계를 분석하고 부실의 원인을 규명하여 중국정부의 기업개혁의 논리를 논증하는데 목적이 있다. 상장기업의 부실 원인과 기업개혁의 논리에 대한 연구는 부실 상장기업만의 문제가 아니라 전체 상장기업이 공유하고 있는 정부와 기업간의 제도문제와 연관이 있다고 본다. 그러므로 본 연구에서는 중국 부실 상장기업을 중심으로 정부와 기업의 제도결합에 대해 모델화를 통한 개념적 분석 틀을 제시할 것이다. 우선 2장에서는 모델화를 결정하는 변수들에 대한 이론적 검토를 시도하고 3장에서는 중국 상장기업의 부실 원인을 부실 상장기업이 자체적으로 제시한 주체적 원인과 현실적으로 존재하는 객관적 원인을 분석하여 이러한 원인들이 정부와 상장기업간의 제도결합과 어떠한 연관성이 있는가를 검토하였다. 4장에서는 상장기업의 부실현황과 부실기업의 특징분석을 제도결합의 모델화를 통하여 분석하고 5장에서는 중국정부의 상장기업 개혁의 논리를 PT쩡빠이원(PT鄭百文)을 예로 논증하였다. The major purpose of this paper is to analyze the system combination between the government and the enterprise through the study on the losing listed enterprises of China, and to analyze the causes of the loss, so as to discuss the logic of enterprise reform of the Chinese government. As for the causes of the deficit of the listed enterprises and the reform of enterprises, the author thinks that, the problem not only lies in the listed enterprise itself, but is related to the system relationship between the listed enterprise and the government. Hence - this research will take the losing listed enterprises of China as the center - to analyze the framework of the mode of combination between the government and the enterprises in system. Chapter Two will do theoretical analysis on the variables determining the mode, and Chapter Three will analyze the subjective causes of the losing listed enterprise itself and the objective causes, and find out the relationship between those causes and the system combination of the government and the listed enterprise. Chapter Four will analyze the deficit status quo of the listed enterprises and the characteristics of the losing enterprises. Chapter Five discusses the logic of listed enterprise reform of the Chinese government, taking PT Zheng Baiwen as the example.

Epoxy adhesive is widely used in electronic apparatus, it is included in the small parts and devices. In particular, the low-heat-resistant material such as polymeric material is needed fast and low-temperature curing behavior because avoided high temperature exposure. In general, it was well known that the curing reaction at low temperature of the epoxy and thiol is faster than the reaction of the epoxy and amine. In this study, we are studied the adhesive behaviors of diglycidyl ether of bisphenol A (DGEBA) and synthesized thiol-polymer by different methods. We adopted the thiol-polymer with different group and different method in order to enable low-temperature and fast curing. The adhesive properties were analyzed by Differential Scanning Calorimetry (DSC), Gel Permeation Chromatography (GPC) and Matrix- Assisted Laser Desorption Ionization - Time of Flight mass spectrometer (MALDI-TOF).
