In the recent context of the Fourth Industrial Revolution, there is growing interest in digital transformation and smart factory as a focal point. But, the Aerospace and Defense (A&D) sector has seen limited research on digital transformation, primarily concentrating on digitally-driven areas. The study validates hypotheses pertaining to the factors that facilitate successful digital transformation within the A&D sector and the influence of digital leadership and dynamic capabilities, employing statistical tools like SPSS and AMOS. The comprehensive analysis reveals that, similar to manufacturing industries, digital leadership in A&D companies exerts an influence on successful digital transformation through dynamic capabilities. Furthermore, digital transformation within the A&D sector has a positive impact on firm performance. This paper offers empirical insights into digital transformation within the A&D sector, shedding light on how successful digital transformation can be achieved within the domestic A&D industry.

Objectives : The purpose of this paper is to study the form, contents and special features found in Qianhuang's life, books, his relationship with his disciples and Shanghansuyuanji's edition and its pass-ons. Methods : The best version among Shanghansuyuanji's copies was selected. Based on this, Qianhuang's life, books and his relationship with his disciples were studied, and Shanghansuyuanji's edition and its pass-ons, form and contents were analyzed. Results & Conclusions: Through study, first I see that Qianhuang was born in the early period of Qing Dynasty and died after the publication of Shanghansuyuanji, Suwen's annotation book probably had not been published yet, his mentor were Fangyouzhi and Yujiayan. Second, I see that he organized Shanghanlun sentences from his own perspective of cause of a disease and cure method. Third, I see that he viewed the diseases of six meridians with the perspective of yinyang and explained the concept of three yins and three yangs in relation to yinyang's ups and downs, and his Yuggyeongjasu theory made possible various interpretations of disease mechanism. Fourth, I see that he held critical views towards the Shanghanlun sentences through the Error Discrimination. Fifth, I see that he viewed disease mechaniam in interdependent relationships or from the point of view of the School of Warming and Tonifying through the Meaning of Herbal Formula. Sixth, I see that he sometimes quoted Neijing in proper ways that fit the disease mechanism in Shanghanlun. On the other hand, he quoted Neijing solely for the reason that identical words are used, but some of these were not proper. Additionally, he criticized the aforementioned annotators for improper quoting Neijing. Consequentially, for reasons mentioned above Qianhuang's Shanghansuyuanji has great importance as a Shanghanlun annotation book.

This study was carried out to construct accurate and scientific system of assessment indicators in selection of National Trust conservation areas, which was new concept of domestic environment movement and offer the raw data of new analytic method by introducing the fuzzy theory and weight for overcoming the uncertainty of ranking decision. To transform the Likert's scale granted to assessment indicators into the type of triangular fuzzy number(a, b, c), there was conversion to each minimum(a), median(b), and maximum(c) in applying membership function, and in using the center of gravity and eigenvalue, there was to decide the ranking. The rankings of converted values applied a mean importance and weight were confirmed that they were generally changed. Therefore, the ranking decision was better to accomplish objective and rational ranking decision by applying weight that was calculated in grouping of indicator than to judge the singular concept and to be useful in assessment of diverse National Trust site. In the future, because AHP, which was general method of calculating weight, was lacked, there was to understand the critical point to fix a pertinent weight, and to carry out the study applying engineering concept like fuzzy integral using $\lambda-measure$.

The electronic structure and properties of Ni$(C_6H_{4-n}F_n)(CO)_2$ ($C_6H_4$=benzyne, n=1-4) complexes have been investigated using hybrid density functional B3LYP theory. Both aromatic natures and nucleus independent chemical shift (NICS) of the benzyne rings have been analyzed. Among mono-, di-, and tri-fluorinated complexes, 3-F, 3,6-F, and 4-H are the most stable isomers, respectively. NICS values calculated at the several points above the ring centers are consistent with those based on the relative energies of the complexes. The atoms in molecules (AIM) analysis indicates that Ni-C bond distance is well correlated with the electron density of a ring critical point (${\rho}_{rcp}$) in all species.

This article shows how the tradition of German historicism and positive historical science contributed to the establishment of German archival system, especially the principle of provenance and original order. The theory of historicism focused on the recognition and realization of the individuality of the history as a whole unit which is made up of the mutually and organically organized cultural entities. The theory of historicism as this kind of world view got its academic basis from the methodology of the positive historical science, namely the critical reviews on the archival sources which exist in mutually and organically organized record entities. In this context, the scholars of the historicism saw the establishment of the efficient archival systems as necessary. To some great degree, the emergence of the principle of the provenance and original order was its logical result. The author of this paper tried to highlight this point of view historically, on the basis of the activities of Ranke, Sybel and Lehmann around and in the Prussia Privy State Archives throughout the 19th century.

The current study employs the nonlocal Timoshenko beam (NTB) theory and von-Kármán's geometric nonlinearity to develop a non-classic beam model for evaluating the nonlinear free vibration of bi-directional functionally-graded (BFG) nanobeams. In order to avoid the stretching-bending coupling in the equations of motion, the problem is formulated based on the physical middle surface. The governing equations of motion and the relevant boundary conditions have been determined using Hamilton's principle, followed by discretization using the differential quadrature method (DQM). To determine the frequencies of nonlinear vibrations in the BFG nanobeams, a direct iterative algorithm is used for solving the discretized underlying equations. The model verification is conducted by making a comparison between the obtained results and benchmark results reported in prior studies. In the present work, the effects of amplitude ratio, nanobeam length, material distribution, nonlocality, and boundary conditions are examined on the nonlinear frequency of BFG nanobeams through a parametric study. As a main result, it is observed that the nonlinear vibration frequencies are greater than the linear vibration frequencies for the same amplitude of the nonlinear oscillator. The study finds that the difference between the dimensionless linear frequency and the nonlinear frequency is smaller for CC nanobeams compared to SS nanobeams, particularly within the α range of 0 to 1.5, where the impact of geometric nonlinearity on CC nanobeams can be disregarded. Furthermore, the nonlinear frequency ratio exhibits an increasing trend as the parameter µ is incremented, with a diminishing dependency on nanobeam length (L). Additionally, it is established that as the nanobeam length increases, a critical point is reached at which a sharp rise in the nonlinear frequency ratio occurs, particularly within the nanobeam length range of 10 nm to 30 nm. These findings collectively contribute to a comprehensive understanding of the nonlinear vibration behavior of BFG nanobeams in relation to various parameters.

This study is on the pedagogical convention of architectural history in Korea, especially that of Western Architecture. Recent institutional change in architectural school in Korea has caused overall restructuring of academic program. In spite of extension in the field of history there was no progress of method and way of thinking. There is no change in the point of view to see the western architecture and its history as a unique and specialized phenomenon in the civilization of mankind. Because of no recognition about for what, for whom, and how to, and because of orientalism, the cultural position of western architectural history and its narrative was not asked. With the help of post-colonialism, de-constructivism and critical historiography this paper tries to show the fundamental premise of western architectural history as a myth and show its prejudice as not being justifiable. The background of the discourse there has been a representation effect with regard to knowledge as a power. we need to escape from this kind of cognitional frame With the analysis of the its premise and narrative we can find it is a historical construct that was made in the age of imperialism. In fact it has a lot of false information and problematic point of view. The Identity and originality of western architecture and its history has no logical reason or foundation if we think that it depends on the difference and comparison with other civilization. For example the explanation of its historical origin western architecture has big difference with Islamic architecture in spite of the resemblance each other. This paper try to show several reasons that discourse of western architectural history can not be survived any longer. So we need to reconstruct new pedagogy with deconstruction for the students of non western, or Korean students. Because it has important effect to see and think about architecture and its history.

In terms of the way we perceive the world, the history of human beings might be said to be a history of two incompatible forces -'science' and 'myth.' Until today, both indispensable aspects have made human existence possible and characterized human culture. Nonetheless, an essential definition of myth has never been clearly explained. What is the general philosophical thought about myth? Current well known interpretations are so called Enlightenment and Romanticism of myth, which both has same criticism that they has not generally considered myth in terms of its technical function or specified contents. One who overcomes the limit of two current extreme beliefs on myth and also who concerned more with the ultimate origin of myth and its relation to the structure of poetry than the source of its vital accomplishments is philosopher Hans Blumenberg. For him myth is an artificial means and an answers to overcome the 'absolutism of reality.' On this point, the research concerns basically two issues. One is to investigate the functional and structural characters of myth through philosopher Hans Blumenberg's anthropological reflections. The other is to analyze architect Tadao Ando's works and thinking. The intention of the paper is not only to explore the relationship between philosophical theory of Blumenberg and Ando's architectural works, but also to suggest a new critical understanding on architecture from mythological point of view. I also expect that this research will suggests a concrete theoretical idea for constructing and construing artistic form and cultural space.

Objectives : The purpose of this study was to investigate Wang Lun (王綸)'s assertion on Ginseng and Astragali Radix and its related arguments that had shown critical or advocative point of views about Wang lun's theory. It was expected that this study would help understand the history of arguments on the usage of Ginseng and Astragali Radix that had been triggered by Wang lun's assertion. Methods : In the process of investigation, this study first looked into the assertions of Wang Lun and the representative arguments about it, which includes Yu Tuan, Wang Ji (汪機), Sun Yikui (孫一奎). And secondly, this study also examined the other following additional arguments that had shown the conclusional aspects of this disputes. Results & Conclusions : Wang Lun (王綸)'s assertion on Ginseng and Astragali Radix proclaimed that in the symptoms of fevers in lung or lack of blood (血) the use of Ginseng and Astragali Radix must be prohibited. This assertion later faced severe criticism by opposers like Yu Tuan, Wang Ji. These opposers asserted that Yang (陽) has the ability of creating Yin (陰), and Ginseng and Astragali Radix could be the right drugs to the symptoms by lack of Yin. But a few approvers like Sun Yikui (孫一奎) had tried to advocate Wang Lun's assertion and casted the question of true meaning of Wang Lun. And In the other following arguments, it could be said that the influence of Wang Lun's assertion had gradually waned but could have been reciprocally accepted in the opposite point of view.
