In the era of the 4th industrial revolution, digital transformation of companies is accelerating regardless of industry. A new business approach is required to provide innovative customer value, innovates processes, and create new markets and customer needs while rapidly applying digital technology in each industry. This study focuses on theoretical reconsideration of service innovation mechanism by digital transformation from a new perspective. To this end, while examining the existing concepts of digital transformation and service innovation, the service innovation mechanisms by digital transformation is reconstructed from the perspective of service-dominant logic and social materialism. The frequent flyer programs of airlines before the era of full-scale digital transformation are explained as evolutionay process of service assemblage based on the actor-network theory and assemblage theory, while innovative service cases following the recent digital transformation of airlines are explained by the process of digital platform, actor engagement and resource integration. Since digital transformation is pursuing a change different from the existing ones, it is necessary to understand service innovation as a process of value co-creation in the service ecosystem from the viewpoint of service-dominant logic and social materialism rather than the traditional technological deterministic viewpoint. In order to capture the nature of service innovation in the era of digital transformation, it is necessary to focus on the innovation framework and process characterized by various actor engagements, changes in their interaction methods, and the results of their emergent resource integration in the service ecosystem, including non-human agency beyond the exisitng anthropoentrism. It would be meaningful to consider innovative service by digital transformation, which airlines have recently introduced competitively, as a process of maximizing customer experience and efficiency of service operation through redesign of human/ non-human interaction around innovative service, that is, digital service platform rather than viewing it as technological result of digitization. Furthermore, understanding the evolutionary process of the formation and dissolution of service assemblage, such as the the combination and separation of other actors ror services in the service ecosystem will give insight into the direction of value creation and innovation of the aviation industry in the era of digital transformation. 4차 산업혁명 시대를 맞이하여 업종을 불문하고 기업들의 디지털 전환이 가속화되고 있다. 각 산업분야에서 디지털 기술을 빠르게 적용하는 한편, 혁신적인 고객가치를 제공하고 프로세스를 혁신하며새로운 시장과 고객 니즈를 창출하는 새로운 비즈니스 접근방식이 요구되고 있다. 본 연구는 디지털전환에 의한 서비스 혁신 메커니즘을 새로운 관점에서 이론적으로 재검토하는데 초점을 맞춘다. 이를위하여 디지털 전환과 서비스 혁신에 관한 기존 개념들을 검토하는 동시에 디지털 전환에 의한 서비스 혁신 메커니즘을 서비스 지배논리와 사회유물론적 관점에서 재구성한다. 본격적 디지털 전환 시대이전 항공사들의 상용고객프로그램을 행위자-네트워크 이론 및 아상블라주 이론에 입각하여 서비스아상블라주 진화과정으로 설명하는 한편, 최근 항공사들의 디지털 전환에 따른 혁신적 서비스 사례를디지털 플랫폼, 행위자 참여 및 자원통합 과정이라는 디지털 서비스 혁신 메커니즘으로 설명한다. 디지털 전환은 기존과는 차원이 다른 변화를 추구하는 것이므로 서비스 혁신을 기존의 기술결정론적 관점보다는 서비스 지배논리 및 사회유물론적 관점의 서비스 생태계의 가치 공동창조 과정으로 이해할필요가 있다. 디지털 전환 시대에서의 서비스 혁신을 이해하기 위해서는 기존 인간중심주의를 뛰어넘는 비인간 행위자의 행위능력을 포함하는 서비스 생태계의 다양한 행위자 참여와 이들의 상호작용 방식의 변화, 그리고 이들의 창발적 자원통합의 결과에 의한 혁신 체계 및 과정에 주목해야 한다. 최근 항공사들이 경쟁적으로 도입하고 있는 디지털 전환에 의한 혁신적 서비스는 디지털화의 기술적 결과물로 보기보다는 혁신적 서비스 중심의 인간/비인간 행위자 상호작용의 재설계, 즉 디지털 서비스 플랫폼을 통한 고객 경험의 극대화 및 서비스 운영의 효율화 과정으로 보는 것이 바람직할 것이다. 나아가 서비스 생태계에서의 다른 행위자 또는 서비스와의 결합 및 분리 등 서비스 아상블라주의 형성과해체의 진화과정으로 이해하는 것이 디지털 전환 시대에서 항공업계의 가치창조 및 혁신 방향에 대한통찰력을 얻을 수 있을 것이다.

( Miklenic Marina ),( Anamarija Stafa ),( Ana Baji ),( Bojan Zunar ),( Berislav Lisni ),( Ivan Kresimir Svetec ) 한국미생물 · 생명공학회 2013 Journal of microbiology and biotechnology Vol.23 No.5

Yeast Dekkera/Brettanomyces bruxellensis is probably the most common contaminant in wineries and ethanol production processes. The considerable economic losses caused by this yeast, but also its ability to produce and tolerate high ethanol concentrations, make it an attractive subject for research with potential for industrial applications. Unfortunately, efforts to understand the biology of D. bruxellensis and facilitate its broader use in industry are hampered by the lack of adequate procedures for delivery of exogenous DNA into this organism. Here we describe the development of transformation protocols (spheroplast transformation, LiAc/PEG method, and electroporation) and report the first genetic transformation of yeast D. bruxellensis. A linear heterologous DNA fragment carrying the kanMX4 sequence was used for transformation, which allowed transformants to be selected on plates containing geneticin. We found the spheroplast transformation method using 1M sorbitol as osmotic stabilizer to be inappropriate because sorbitol strikingly decreases the plating efficiency of both D. bruxellensis spheroplast and intact cells. However, we managed to modify the LiAc/ PEG transformation method and electroporation to accommodate D. bruxellensis transformation, achieving efficiencies of 0.6-16 and 10-20 transformants/μg DNA, respectively. The stability of the transformants ranged from 93.6% to 100%. All putative transformants were analyzed by Southern blot using the kanMX4 sequence as a hybridization probe, which confirmed that the transforming DNA fragment had integrated into the genome. The results of the molecular analysis were consistent with the expected illegitimate integration of a heterologous transforming fragment.

반복적 염색체 삽입 형질전환에 의한 Saccharomyces diastaticus로의 외래 α-Amylase 유전자의 도입

김근 수원대학교 기초과학연구소 1995 基礎科學論文集 Vol.4 No.-

To overcome the unstable mitotic stability of heterologous α-amylase gene located on the episomal plasmid, two linearized integrating vectors, YIpMS△R(LEU2) and YIpMS△R(LEU2/URA3) were constructed and used for integrative and repetitive integrative transformation of Saccharomyces diastaticus secreting glucoamylase. The resulting tranformants showed increased amylolytic activities and mitotic stabilities compared to the original recipient. The repetitively integrated transformant showed higher amylolytic activity and mitotic stability of α-amylase gene than the once integrated transformant. The highest mitotic stability of repeated integrative transformant was 99.2% after 100 generations of cell-multiplication while the mitotic stabilities of episomal transformant and once integrative transformant were 0.0 and 73.3%, respectively.

MICE 기업의 디지털 전환(DX) 결정요인에 관한 연구

노현숙,현병환 한국관광진흥학회 2022 관광진흥연구 Vol.10 No.3

In 2004, Professor Erik Stolterman of Sweden first referred to 'a phenomenon in which human life is improved in a better direction using IT technology' as Digital Transformation (DX). If you look at the transformation, you can use digital technology to improve your business and expand and change your business area. In other words, the core of the 4th industrial revolution can be seen as digital transformation in all areas of individuals and businesses. A company's digital transformation requires a cool-headed, correct awareness and desirable response to situations that can be both an opportunity and a threat depending on the circumstances and judgment. The MICE industry is no exception. Since 2010, the MICE industry has been combined with digital technology and has become a driving force for innovative growth in industries that have entered a low-growth phase, leading the growth and innovation of the MICE industry. In particular, a number of events in the form of Untact and hybrids were held in the context of COVID-19, accelerating the digital transformation of MICE companies. This study reveals that in order to implement a successful digital transformation that increases business performance and efficiency, a positive organizational culture of a company is a prerequisite, and it studies the perception and attitude of MICE company members to develop a strategic perspective for digital transformation of MICE companies. is to establish Against this background, the purpose of this study is to examine the perception of digital transformation of MICE companies and to empirically analyze the factors that promote digital transformation. To this end, literature research was conducted, and prior research was conducted on the relationship between digital transformation awareness and technology acceptance, external responses to digital transformation and digital transformation readiness, digital transformation intention and digital transformation implementation, and data on MICE company employees were collected. I want to analyze Through this, we intend to present theoretical and practical implications for digital transformation of MICE companies preparing for the 4th industrial innovation and post-corona era. 2004년 스웨덴의 에릭 스톨터만(Erik Stolterman) 교수가 최초로 ‘IT 기술을 활용해 인간의 삶이 보다더 나은 방향으로 개선되는 현상’을 디지털 전환(Digital Transformation, DX)이라고 언급하였으며, 기업측면의 디지털 전환을 살펴보면 디지털 기술을 활용해 비즈니스를 개선하고 사업영역이 확장·변화되는 것이다. 즉 4차 산업혁명의 핵심은 개인과 기업의 모든 영역에서 디지털 전환으로 볼 수 있다. 기업의 디지털 전환은 상황과 판단에 따라 기회도 위협도 될 수 있는 상황에 냉철하고 올바른 인식을 갖고 바람직한 대응을 해야 한다. MICE 산업도 예외는 아니다. 2010년 이후 MICE 산업은 디지털 기술과 결합되며 저성장 국면에 진입했던 산업의 혁신적 성장 원동력이 되었고, MICE 산업의 성장과 혁신을 주도하고 있다. 특히 코로나 19 상황에서 언텍트(Untact)와 하이브리드 형태의 행사가 다수 개최되며 MICE기업의 디지털 전환은 가속화되었다. 본 연구는 경영성과와 효율성을 높이는 성공적인 디지털 전환을 실행하기 위해서는 기업의 긍정적 조직문화가 배경이 전제되어야 함을 밝히고, MICE 기업 구성원들의 인식과 태도를 연구해 MICE 기업의 디지털전환을 위한 전략적 시각을 정립하는데 있다. 이러한 배경 하에 MICE 기업의 디지털 전환에 대한 인식을살펴보고, 디지털 전환을 촉진하기 위한 요인을 실증적으로 분석하는데 목적을 두고 있다. 이를 위해 문헌연구를 하고 디지털 전환 인식과 기술 수용성, 디지털 전환에 대한 외부반응과 디지털 전환 준비정도, 디지털전환 의사와 디지털 전환 실행 간의 관계에 대한 선행연구를 조사하고 MICE 기업 종사자에 대한 자료를 수집하여 분석하고자 한다. 이를 통해 4차 산업 혁신을 대비하고 포스트 코로나 시대를 준비하는 MICE 기업의 디지털 전환을 위한 이론적, 실무적 시사점을 제시하고자 한다.

CPI 보안 강화 코드 변환의 실용적인 동등성 검사 기법

이재서,최태형,이규호,유재관,배경민 한국정보과학회 2019 정보과학회논문지 Vol.46 No.12

Code transformation is widely used to improve the performance and security of programs, but serious software errors can occur in this process if the generated program is not equivalent to the original program. There are a number of approaches for translation validation that can be used to prove the equivalence of programs, but the high cost of proof checking restricts the applicability of these techniques for large programs. In this paper, we propose a practical approach for checking the correctness of LLVM code transformation. We first prove the correctness of the transformation rules using automated theorem proving before compilation. We then perform a simple code analysis method—as opposed to directly proving the program equivalence— to check whether the transformations rules are correctly applied to the generated code. As the complexity of the proposed code analysis is linear, our technique can be effectively applied to large programs, unlike previous techniques. To prove the effectiveness of the proposed approach, we present a case study on LLVM code transformation for a code pointer integrity instrumentation. 코드 변환 시의 동등성이 만족되지 않을 경우 소프트웨어 오류를 야기할 수 있다. 기존의 정리 증명을 통한 코드 변환의 동등성 검사는 코드의 규모가 커질수록 기하급수적으로 높은 비용이 요구되기 때문에 실제 소프트웨어 개발 시에 적용하기 어렵다. 본 논문에서는 규칙 증명과 코드 검사의 분리를 통하여 실용적인 LLVM의 코드 변환의 동등성 검사 기법을 제안한다. 먼저 주어진 코드 변환 규칙의 동등성은 자동정리증명을 통하여 컴파일 전에 별도로 증명한다. 그리고 컴파일 과정에서 변환 전과 후의 코드에 대한 정적 분석을 수행하여 코드 변환 규칙이 생성된 코드에 올바르게 적용되었는지 검사한다. 이러한 코드 분석의 수행 시간은 코드의 규모에 선형으로 증가하기 때문에, 규모가 큰 코드에도 효과적으로 적용될 수 있다. 제안된 연구를 코드 포인터 무결성(code pointer integrity) 보안강화 코드변환에 적용하여 LLVM 기반 도구제작에 활용하였다.

Combination of ammonium nitrate, cerium chloride and potassium chloride salts improves Agrobacterium tumefaciens-mediated transformation of Nicotiana tabacum

Maheshwari, Priti,Kovalchuk, Igor 한국식물생명공학회 2013 Plant biotechnology reports Vol.7 No.2

The frequency of plant transformation can be improved by addition of various chemical into transformation media. In the past, we showed that exposure of tobacco, wheat and triticale explants to ammonium nitrate, cerium and lantanium chloride and potassium chloride resulted in an increase in the frequency of transformation. Here, we tested whether a combination of increased concentrations of the aforementioned salts yielded a higher transformation frequency. We found that exposure to 61.8 mM ammonium nitrate caused a 5.0-fold increase in transformation frequency, whereas exposure to 1.0 ${\mu}M$ cerium chloride or 47.0 mM potassium chloride resulted in 1.2- and 2-fold increases, respectively. Exposure to 61.8 mM ammonium nitrate and 1.0 ${\mu}M$ cerium chloride led to a 4.8-fold increase in transformation frequency, whereas exposure to 61.8 mM ammonium nitrate and 47.0 mM potassium chloride let to a 5.2-fold increase. Finally, exposure to 61.8 mM ammonium nitrate, 1.0 ${\mu}M$ cerium chloride and 47.0 mM potassium chloride produced a 5.1-fold increase. The analysis of the intactness of T-DNA borders showed that plants exposed to ammonium nitrate and a combination of ammonium nitrate with other salts had the more intact right borders and the less intact left borders. The best results were observed when all three salts (ammonium nitrate, potassium chloride and cerium chloride) were used. Thus, we concluded that the addition of cerium chloride and potassium chloride does not substantially improve the transformation rate beyond the improvement observed upon treatment with 61.8 mM ammonium nitrate, but may slightly improve the intactness of T-DNA borders.

An inversion of the conical Radon transform arising in the Compton camera with helical movement

Kiwoon Kwon 대한의용생체공학회 2019 Biomedical Engineering Letters (BMEL) Vol.9 No.2

Since the Compton camera was fi rst introduced, various types of conical Radon transforms have been examined. Here, wederive the inversion formula for the conical Radon transform, where the cone of integration moves along a curve in threedimensionalspace such as a helix. Along this three-dimensional curve, a detailed inversion formula for helical movementwill be treated for Compton imaging in this paper. The inversion formula includes Hilbert transform and Radon transform. For the inversion of Compton imaging with helical movement, it is necessary to invert Hilbert transform with respect tothe inner product between the vertex and the central axis of the cone of the Compton camera. However, the inner productfunction is not monotone. Thus, we should replace the Hilbert transform by the Riemann–Stieltjes integral over a certainmonotone function related with the inner product function. We represent the Riemann–Stieltjes integral as a conventionalRiemann integral over a countable union of disjoint intervals, whose end points can be computed using the Newton method. For the inversion of Radon transform, three dimensional fi ltered backprojection is used. For the numerical implementation,we analytically compute the Hilbert transform and Radon transform of the characteristic function of fi nite balls. Numericaltest is given, when the density function is given by a characteristic function of a ball or three overlapping balls.

Double Challenge of Integration and Transformation in 1990s-Siberia between Russia and Northeast Asia

윤익중 한국세계지역학회 2006 世界地域硏究論叢 Vol.24 No.2

After the disintegration of the Soviet Union, regionalism became an important theme for Northeast Asia in 1990s. As the geopolitical obstacles to greater economic integration seemed gradually to fade away beginning with Gorbachev’s perestroika, and as the economic miracles of Japan and the ‘four tiger states’ were repeated all over the region, time seemed ripe for regional integration in Northeast Asia. This was especially true for market integration in the case of the Russian parts of Northeast Asia. In this respect, both economic and security aspects were of great importance for Siberia and the Russian Far East. These were perceived as opportunities to bypass the hardships of transition elsewhere experienced in Russia and also as a chance to gain greater autonomy for the first time throughout Siberian history. However, by the late 1990s, Siberia’s great expectations remained still unfulfilled, as well concerning economic integration as political integration. Nevertheless, this paper concludes that there seemed several positive reasons for further cooperation among them in the near future, in aspects of both at the potential economic and at the strategic role of Siberia in Northeast Asia. In other words, it is hard to say Russia’s double challenge of integration and transformation in 1990s was only unsuccessful although there were few visible achievements. It is clear that Siberian experience in 1990s will clearly help more concrete regional integration and cooperation in Northeast Asia in the 21st century. 구 소연방 붕괴 후 지역주의는 동북아시아에서도 매우 중요한 정치적/경제적 이슈가 되었다. 고르바초프의 신사고정책 등에 편승하며 냉전시대에 존재하였던 동북아시아에서의 지정학적인 장애요소는 탈냉전시대 지역경제통합을 위하여 사라지는 듯 하였다. 즉, 1990년대 초 동북아시아에서의 지역통합은 시기적으로 무르익은 듯하였다. 이러한 현상은 특히, 동북아시아와 접하고 있는 러시아의 지역(시베리아와 극동)에서 탈냉전시대 시장통합적인 측면에서 매우 실현가능성이 있었다. 사실, 시베리아와 러시아 극동지역은 경제적 그리고 안보적인 측면에서 모두 중요하였다. 이 지역에서는 지역통합의 지역주의를 1990년대 체제전환의 어려움을 경험하는 러시아의 다른 지역과는 달리 이를 극복할 수 있는 기회로 인식하였으며 또한 시베리아 역사상 처음으로 중앙정부로부터 자치권을 획득할 수 있는 기회로 인식하였다. 그러나, 1990년 말에 이르러서도 그러한 지역통합의 많은 기대는 정치적/경제적인 측면에서 여전히 이루어지지 않았다. 그럼에도 불구하고, 가까운 미래에 러시아의 시베리아(극동) 지역은 동북아시아에서 경제적인 잠재력과 전략적인 역할에서 동북아시아 국가들과 더 많은 협력을 할 긍정적인 요인들이 분명히 있다. 다시 말해, 1990년대 러시아가 추구하였던 지역통합과 체제전환의 동시적 시도는 그 가시적 성과가 비록 미미하지만 단순히 실패라고 규정할 수는 없다. 1990년대 시베리아의 경험은 21세기 동북아시아에서의 지역통합과 협력에 크게 기여할 것이다.

GENERALIZED ANALYTIC FEYNMAN INTEGRALS INVOLVING GENERALIZED ANALYTIC FOURIER-FEYNMAN RANSFORMS AND GENERALIZED INTEGRAL TRANSFORMS

장승준,정현수 충청수학회 2008 충청수학회지 Vol.21 No.2

In this paper, we use a generalized Brownian motion process to define a generalized analytic Feynman integral. We then establish several integration formulas for generalized analytic Feynman integrals, generalized analytic Fourier-Feynman transforms and generalized integral transforms of functionals in the class of functionals E0. Finally, we use these integration formulas to obtain several generalized Feynman integrals involving the gen-eralized analytic Fourier-Feynman transform and the generalized integral transform of functionals in E0.
