The main purpose of the study is to analyze the main aspects of state regulation of the banking business in the context of social and digital transformation. One of the key elements of the functioning of the economy of any country are banks that ensure the redistribution of financial resources and stimulate economic growth. However, the banking sector, like other activities, is dynamic and depends on the pace of development and forms of technological progress that affect the forms and types of information and digital technologies, as well as the globalization and remoteness of banking services. Accordingly, the need for effective implementation of the latest technologies becomes relevant, which will not only help increase consumer satisfaction with the banking product, but also ensure the development of the country's financial sector. As a result of the study, trends in the development of state regulation of the banking sector in the digital economy were identified.

The CMS(color management system) software was to enable consistent color reproduction from original to reproduction. The CMS was to create RGB monitor and printer characterization profiles and then use the profiles for device independent color transformation. The implemented CMM(color management module) used the CIELAB color space for the profile connection. Various monitor characterization model was evaluated for proper color transformation. To construct output device profile, SLI(sequential linear interpolation) method was used for the color conversion from CMYK device color to device independent CIELAB color space and tetrahedral interpolation method was used for backward transformation. UCR(under color removal) based black generation algorithm was used to construct CIELAB to CMYK LUT(lookup table). When transforming the CIE Lab colour space to CMYK, it was possible to involve the gray revision method regularized in the brightness into colour transformation process and optimize the colour transformation by black generation method based on UCR technique. For soft copy colour proofing, evaluating several monitor specialism methods showed that LUT algorithm was useful. And it was possible to simplify colour gamut mapping by constructing both the look-up table and the colour gamut mapping algorithm to a reference table.

최근 성능향상과 개발의 편리성을 주요 특징으로 보완한 EJB 3.0 명세가 발표되었다. 이에 따라 개발자들은 EJB 3.0 기반의 애플리케이션 환경에서 EJB 2.1 컴포넌트 전체를 EJB 3.0 컴포넌트로 완전 대체하기보다는 성능향상이 요구되는 컴포넌트부터 점진적 변환하는 방법을 주로 고려하게 되었다. 그러나 기존 연구는 애플리케이션의 서비스를 고려하지 않기 때문에 점진적 변환을 하는데 문제가 있고, 상이한 명세의 변환 방법으로 EJB 3.0 완전 대체 시 컴포넌트의 호환의 문제와 재사용을 하는데 어려움이 있다. 본 연구에서는 기존 애플리케이션에서 제공하였던 서비스를 고려하며, EJB 3.0 완전 대체 시에서도 컴포넌트의 호환과 재사용이 가능한 세가지 변환 기법을 제안한다. 제안하는 변환 기법은 직접 컴포넌트 연결을 하는 직접 변환 기법 EJB 커넥터를 사용하는 간접 변환 기법 그리고 간접 변환 기법에 템플릿 패턴을 적용하는 간접 템플릿 변환 기법으로 점진적 변환을 위한 기법들이다. 이에 제안하는 변환 기법을 재사용과 초당 처리량이라는 평가 기준으로 비교 검증하며, 본 연구를 통해 도출된 EJB 3.0 변환시의 특성들을 기반으로 기법 선택의 기준을 제공한다.

본 연구는 성숙도 모델 개념을 활용하여 디지털 전환 성과를 측정할 수 있는 지표 개발을 시도하였다. 디지털 전환을 위해서는 단순한 서비스 개선이 아니라 조직, 업무 변화까지를 고려할 필요가 있다. 여기서는 우리나라의 대표적인 과학기술정보서비스 기관인 KISTI의 디지털 전환 측정을 위한 모델 개발을 목표로 하였다. KSITI는 이미 디지털 전환을 위한 BPR 작업을 수행한 바 있으며, 성숙도 모델 개념을 차용하였다. 단, BPR에서는 해당 결과를 측정할 수 있는 방법은 존재하지 않는다. 본 논문에서는 성숙모 모델을 기반으로 디지털 전환을 측정할 수 있는 지표를 개발하였다. 지표개발은 모델 개발과 평가 두 가지 방법으로 수행하였다. 모델 구성을 위한 사례는 기존 KISTI에서 수행한 관련 연구, 다양한 국내·외 사례를 통해 이루어졌다. 검증 전 모델은 대분류를 기준으로 기술(37개), 데이터(45개), 전략(18개), 조직(인력)(36개), (사회적)영향력(14개)이었다. 검증 후에 최종 모델은 기술(20개/17개 지표 탈락), 데이터(36개/9개 지표 탈락), 전략(18개/유지), 조직(인력)(30개/6개 지표 탈락), (사회적)영향력(13개/1개 지표 탈락)으로 구성되었다.

The process and change of convergence in the economy and industry with the development of digital technology and combining with new technologies is called Digital Transformation. Specifically, it refers to innovating existing businesses and services by utilizing information and communication technologies such as big data analysis, Internet of Things, cloud computing, and artificial intelligence. Digital transformation is changing the shape of business and has a wide impact on businesses and consumers in all industries. Among them, the big data and analytics market is emerging as one of the most important growth drivers of digital transformation. Integrating intelligent data into an existing business is one of the key tasks of digital transformation, and it is important to collect and monitor data and learn from the collected data in order to efficiently operate a data-based business. In developed countries overseas, research on new business models using various data accumulated at the level of government and private companies is being actively conducted. However, although the trade and import/export data collected in the domestic public sector is being accumulated in various types and ranges, the establishment of an analysis and utilization model is still in its infancy. Currently, we are living in an era of massive amounts of big data. We intend to discuss the value of trade big data possessed from the past to the present, and suggest a strategy to activate trade big data for trade digital transformation and a new direction for future trade big data research.

A data structure representing 3-D objects was designed for the personal computer. It is very simple to be used in the personal computers which have small memory and low speed. A homogeneous transformation for developing 3-D objects was derived. Each developing procedure consists of five transformations : one translational-three rotational-one translational. Developing a solid is a creative work. So the results of developing vary with the order of surfaces to be developed. One method to reduce the length of seam was considered. The programs used in this study were written in Pascal and Assembly and a modeller that generates 3-D primitives was included. This program is an interactive dual-screen system. While all the menus in Korean are displayed at the monochrome monitor, the development figures with projective views are drawn at the color monitor. The program has wide applications for plate works.

The microstructure of the reagion of carters, created by Cu and W-Cu shaped charge jets, in a 1020 mild steel target has been intestiaged. The region ahead of the crater created by the Cu shaped charge jet, reveals dramatic grain refinement implying the occurrence of a dynamic recrystallization, while that of W-Cu one dose a martensitic transformation indicative of heating up to an austenitic region followed by rapid cooling.The impacting pressure calculated when the W-Cu shaped charge jet encounters the target is higher than that of the Cu one. The micro-hardness of the region ahead of the crater created by the W-Cu shaped charge jet is also higher than that of the Cu one. The microstructure of W-Cu slug remained in the inside of the craters depicts the occurrence of the remarkable elongation of W particles during the liner collaphse. From these results, the microstructural variation of the region ahead of the crater with Cu and W-Cu shaped charge jets is discussed in trems of the pressure dependency of the transformation region of ferrite and austenite phases.

Practical automated flat pattern generation with inbuilt production features for doubly curved sheet metal components (SMCs) is addressed here utilizing a new and unique Point Transformation Algorithm (PTA). This is the third in the series of papers on practical Flat Pattern Development (FPD) [8] and Production Loft Generation Systems (PLGS) [9] complementing the pioneering work [6,7]. In the first two publications, automated loft generation programs have addressed sheet metal components having a Principal Flat Surface (PFS) only. The flat pattern development of 3-D components that do not have the flat surface(termed as Non-PFS components) having complex features of double curvature in addition to cutouts and nibbled holes typical of aircraft components were so far not addressed due to lack of relevant published algorithms. This paper traces the evolution of developments and provides the record of fully illustrated, automated loft generation scheme for aircraft SMCs including the Non-PFS components which underwent validation through production tests by sponsors. Details of some of the unique features of the system like simplified surface model generation, termed as topological model and powerful algorithms deployed with potential for CAD/CAM applications are included.

We have achieved efficient transformation system for forage-type tall fescue plants by Agrobacterium tumefaciens. Mature seed-derived embryogenic calli were infected and co-cultivated with each of three A. tumefaciens strains, all of which harbored a standard binary vector pIG121Hm encoding the neomycin phosphotransferase II (NPTII), hygromycin phosphotransferase (HPT) and intron-containing $\beta$-glucuronidase (intron-GUS) genes in the T-DNA region. Transformation efficiency was influenced by the A. tumefaciens strain, addition of the phenolic compound acetosyringone and duration of vacuum treatment. Of the three A. tumefaciens strains tested, EHA101/pIG121Hm was found to be most effective followed by GV3101/pIG121Hm and LBA4404/pIG121Hm for transient GUS expression after 3 days co-cultivation. Inclusion of 100 $\mu$M acetosyringone in both the inoculation and co-cultivation media lead to an improvement in transient GUS expression observed in targeted calli. Vacuum treatment during infection of calli with A. tumefaciens strains increased transformation efficiency. The highest stable transformation efficiency of transgenic plants was obtained when mature seed-derived calli infected with A. tumefaciens EHA101/pIG121Hm in the presence of 100 $\mu$M acetosyringone and vacuum treatment for 30 min. Southern blot analysis indicated integration of the transgene into the genome of tall fescue. The transformation system developed in this study would be useful for Agrobacterium-mediated genetic transformation of tall fescue plants with genes of agronomic importance.
