The microstructures of the HAZ (Heat Affected Zone) are generally different from the base metal due to rapid thermal cycle during welding process. Particuraly, CGHAZ (Coarsened Grain Heat Affected Zone) near the fusion line is the most concerned region in which many metallurgical and mechanical discontinuities have been normally generated. A computer program by the numerical formularization of phase transformation during cooling with different rates was developed to generate the CCT diagram, and to predict microstructural (phase) changes in the CGHAZ. In order to verify simulated results, isothermal and continuous cooling transformation experiments were conducted. The simulated and experimental results showed that the developed computer model could successfully predict the room temperature microstructural changes (changes in volume fraction of phases) under various welding conditions (heat input & cooling rate $(Δt_{8/5})$).

Accroding to "Hwangjenaegyeong(黃帝內經)", when the food and drink[水穀] enter the mouth, they divided into two different things with solid food[食] and liquid food[飮], then transformed and absorbed into Jeong(精), Gi(氣), and Jinaek(津液) and spread to the entire body. The movement and transformation[運化] of the food and drink in the body can be distinctly described with the circulation of the Yeonggi(營氣) Wigi(衛氣) and metabolism of Jinaek. The leftover food[糟粕] which is not transformed into Jinaek, not delivered to the Jangbu(藏府) like Gan(肝), Shim(心), Bi(脾) and Pe(肺), brought to the Daejang(大腸) and transported through the baekmun(魄門). Or some of them are verified at the Hoejang(廻腸) and brought to the Banggwang(膀胱) through the Hacho(下焦) then transpired them outside the body. The distinguishing mark of the movement and transformation of the food and drink and its transpiration in the "Hwangjenaegyeong" is that the Sin(腎) of five jangs is exclude from the process of the movement and transformation and the process is explained with the fluid like Gi and Jinaek. From the "Nangyeong(難經)", developing of Myeongmun(命門) theory, the importance of the Sin in the delivering process of the food and drink is remarkably highlighted; however in the late period of Chosun dynasty(朝鮮), Seokgok Igyujun(石谷 李奎晙) denied the temporary theory of Myongmun and asserted the original interpretation recovery of "Hwangjenaegyeong".

This study analyzed the meanings and drives, and government roles in NIS transformation process. Specifically, I deal with changes in the S&T policy and S&T public administration system as NIS changed from catch-up to post catch-up. As a result, S&T policy and administrative structure has changed as key elements of a new form of steering the transformation process. Though changed from direct to indirect, the role of the state remains strong in 'vision creation' and 'discursive coordination' as supporter and facilitator of the NIS transformation process. Especially, administration structure has been changed to strengthen decentralized pluralism and linkages and cooperation between government and private, between firms and universities, among inter related ministries.

Government agencies and companies are establishing and promoting digital transformation strategies in various industrial fields, and are leading the era of the 4th industrial revolution through successful technological innovation. In this time of change, we can see many stories of global companies Nike and Starbucks as successful examples of digital transformation. These two companies are showing successful results through digital transformation. Domestic companies are also conducting digital innovation based on mobile, cloud, IoT, artificial intelligence, and AR/VR technologies, and are establishing RPA (Robotic Process Automation) processes for high efficiency and high productivity. In this paper, we introduce the 3D digital twin space construction automation process technique using data from the entire construction cycle of design, construction, and maintenance of the construction industry, and look into the digital transformation strategy of the construction industry in the future.

The article examines the key constants of reengineering the modern educational cluster, associated with the processes of digital transformation of all spheres of modern socio-cultural space. The first constant is the strategic rethinking of the educational process organization and awareness of the new roles of all participants (tutors, applicants, controlling elements, etc.). The other constant involves practical re-design of the system of educational services, which consists in the reorientation from the traditional model of education functioning for society to the implementation of the educational format in the form of new projects (structural, target, business). Consequently, the purpose of the study is to highlight the attitudes relevant to the modern realities of information and technological support of education in the context of socio-economic interactions of society. The criteria for the reengineering of educational concepts and the structural organization of the educational sphere are defined. The modern world is going through a period of complete digital transformation of all spheres of public activity. The scientific intelligence notes that education is no exception in these processes, as the dependence of educational realities on information and computer technologies is now noted. The COVID-19 pandemic, for all its tragedy, was also a kind of trigger, clearly marking the new components that have become defined in the organization of the educational process. The conclusion is made that the use of digital technologies in the organization of the educational institution or in the organization of the educational process has become not an auxiliary element, but a dominant factor. Mobility, dynamism, interdisciplinarity, synergy - all these aspects are relevant for socio-economic interactions of society and should be provided by educational programs. The results of the study can be used in the reorganization processes of educational institutions and institutions. Further research requires aspects of the analysis of the foreign experience of reengineering in education, carried out taking into account digital transformations of modern sociocultural space.

In this paper a new process capability index $C_{psks}$ is introduced for non-normal process. $C_{psks}$ that is proposed by transformation of the $C_{psks}$ incorporates an additional skewness correction factor in the denominator of $C_{psks}$. The use of each technique is illustrated by reference to a distribution system which includes the Pearson and Johnson functions. Accordingly, $C_{psks}$ is proposed as the process capability measure for non-normal process.

Recently, ultra high strength products can be manufactured by the hot press forming process of Boron steel in automotive and electronics industries. In order to get high strength, the hot press forming should be accompanied by quenching process inducing phase transformation. There are several types of the hot press forming processes according to the quenching method, water quenching and die quenching, etc. In the study, the process was numerically and physically simulated to compare the two types of quenching processes, and then the strength, hardness and dimensions of the products were compared with try-outs.

Most of flated scanners and digital cameras in prepress process utilize CCD technology. Device calibration and characterization process is needed to transform the device dependent color to the device independent color. ICC profiles for digital input devices encapsulated information relating the device values to CIELAB or CIEXYZ coordinates. The main purposes of this article is to evaluate some of the transformation methods based on ICC proposed device profiles and to propose optimal color transformation method for accurate color imaging in printing process.
