COVID-19 occurred in China in December 2019 and spread to the world. Untact culture becoming commonplace due to the spread of COVID-19, is accelerating digital transformation across society. The government is increasing government fund to overcome national crisis situations such as COVID-19. In order to efficiently execute these government funds, the government and policy financial institutions need to come up with two measures. One is to establish a transparent government fund execution process, and the other is to secure the objectivity of the review process. In this paper, to solve this problem, we designed the execution process of government funds from the government to end users with Consortium Blockchain, and designed a machine learning algorithm for internal review of policy financial institutions. The research data proposed in this paper will be helpful in setting the future government policy direction for government fund execution.

The purpose of this study is to develop a photomontage expression in order to express a characteristic personality and creativity of artists of effectively in fashion illustration. The results of this study were as follows : 1) Because of a fashion and a human body were the major subjects in fashion illustration, human body transformation and composition between a human body and heterogeneous objects by photomontage appeared with a lot of works. 2) Photomontage appeared with a parody in a truth recurrence differ from a visual art, a parody seemed to be a humor with recurrence image of the original and it appeared with the general public image and it is effective in message delivery. 3) It was a stopped screen. but photomontage was expressed through overlapping and reiteration was characteristic, and it appeared with movement. a direction, a speed and rhythm effectively. 4) One screen of general chapter was only to express limited meaning, but after screen of a lot of chapter, it was able to express that was borrowed and reconstructive with a lot of contents or different contents are more than before. 5) It is changed, and composited images have a multiple point of time, and it extend a space-time limit, visual limit and an expression enabled a multidimensional space-time. Moreover, photomontage neglects unique sincerity and fact of a photo by development and utilization of computer graphic. and it can get a screen effect to spread in the virtual world as abstraction and hyper-reality. Therefore, if various photomontage expression apply to fashion illustration works, it can overcome a limit of a visual expression. and it is able to become an important way for expanding a filed of expression and enhancement of a practical function gradually in fashion illustration

This paper proposes a method to insert virtual objects into a real video stream based on feature tracking and camera pose estimation from a set of single-camera video frames. To insert or modify 3D shapes to target video frames, the transformation from the 3D objects to the projection of the objects onto the video frames should be revealed. It is shown that, without a camera calibration process, the 3D reconstruction is possible using multiple images from a single camera under the fixed internal camera parameters. The proposed approach is based on the simplification of the camera matrix of intrinsic parameters and the use of projective geometry. The method is particularly useful for augmented reality applications to insert or modify models to a real video stream. The proposed method is based on a linear parameter estimation approach for the auto-calibration step and it enhances the stability and reduces the execution time. Several experimental results are presented on real-world video streams, demonstrating the usefulness of our method for the augmented reality applications.

This study attempts to find out the characteristics of digital currency and currency transformation through the analytical descriptions of the literature. In the early days of the emergence of new currency, market-oriented autonomous monetary adjustment was made along with various attempts by the private sector, and then government-centered central currency management and coordination were made for the national monopoly of profits and power. Digital currency can be seen as the emergence of a new form of money that will bring about paradigm changes. CBDC can be divided into direct and indirect types. CBDC is expected to require a strategic approach by the government or firm as it will bring about changes in the ecosystem of related industries. Libra is a stablecoin designed to minimize price fluctuations, and if it succeeds in commercializing it, it is expected to bring about revolutionary changes in the financial industry around the world.

Eddy current (EC) testing methods are widely used in a variety of applications including the inspection of steam generator tubes in nuclear power plants, aircraft parts and airframes. A key factor that affects the EC signal is lift-off which means the physical distance between a sensor and a specimen in the testing. In practice, it is difficult to keep track of the actual value of the lift -off during a specific experiment, simulation or testing in the field, which is essential for accurate interpretation of the signal to be used in the following steps. Hence it is necessary to have a scheme to render the EC signal invariant to the effects of lift-off in spite of the changes in the real world. This paper describes a new method for compensating EC signals for variations in lift-off by acquiring an invariance feature using a homomorphic operator and neural network techniques. The signals from various lift-offs are transformed to obtain a zero lift-off equivalent signal that can be subsequently used for defect characterization in the next step.

This paper conceptualizes the two-faced platform based on interface studies and two-sided market theory to critically analyze today's information technology culture such as the Internet. With this conceptual framework, the Internet can be investigated to have two faces, in which the square of user's openness, sharing, and participation is unfold on the front face, whereas the market of tracking, surveillance, and control of user's activities is formed on the other face. The two faces contradictorily coexist, resulting in technological and cultural dynamics on the Internet. Therefore, the Internet today as a two-faced platform can be described as a square-market interface. By analyzing on transformation of the web architecture, shift of informational commodity from content to data, and web bugs' user tracking across two faces, it examines how the world wide web itself can function as a two-faced platform. Lastly, implications and further works are suggested to improve the two-faced platform as a conceptual framework and to deeply analyze broader information technology culture based on it.

This study is to present 'game-storytelling' is based on 'hero-storytelling' and to transform the basic pattern which is extracted from 'heroic-storytelling' so that it can be applied to 'game-storytelling'. 'Game-storytelling' has the similar foundation as 'heroic storytelling'. It begins with an extraordinary birth, introduction to the strange world, exploration, adventure, birth of a hero and finally return of a hero. The most distinctive feature of stages is the conquest of outer and internal limitation. Each stage goes through the process of compensation and outer, internal acknowledgements. These processes are the structural core of game storytelling. Generally, stage 1 to 5 includes background stories, stage 6 to 9 are the progress of game, and stage 10 to 12 are the transformation of game with rules and genre.

This study explores the change of family policy in Germany focused on political ideologies and instruments of CDU/CSU and SPD. In past 50 years after the 2. world war the family policy in Germany has been influenced by ideologies of 2 major political parties. With conservative political perspectives, CDU and CSU intend to strengthen the institution family and traditional division of domestic work. Therefore, they prefer indirect support methods by income tax benefit for family as political instrument. SPD with liberal political perspectives intends to support working married women and children. As political instrument SPD prefers allowance for child to indirect support system. This different political perspectives of 2 major parties have been reflected automatically on the federal administrative system(BMFSFJ) which takes responsibility of family policy in Germany. Through the analysis of attitudes to family policy of major parties in Germany this paper attempts to be manifest the problem of korean family policy and to find implications of german modell.

In this paper, a high-level process control language is developed to construct multi-loop controllers for large scale process control systems. Function locks are defined which are basic functions necessary to configure a multi-loop controller. Each block is presented to the function code which is a line of ASCII codes and has the characteristics to be simple and to be easily understood. A control algorithm for a process is attained by means of the arrangement of function codes with order. In order to be used to various environments of target hardwares, a transformation program is prepared that transfers a control program configured by function codes to a C-language program. The proposed control language is easy and simple to use, possible to expend, and able to apply to various control systems. Simulation results are included to show the availability for the usage of the proposed control language in real world.
