Investigation for industrial revolution has been recognized as an important issue of historical science, since industrial revolution itself was a historical moment in modern economic society and in the forming of modern capitalistic culture. If clothing culture had been developed in close relation to social culture. industrial revolution which gave a base for modern capitalistic culture, would be a birth of modern clothing as well as a moment for modernization of western clothing. As it takes for granted that industrial revolution, historical phenomenon is a developmental base of modern clothing culture. This study tried to enlighten the origin of modern clothing culture phenomenon with investigation of industrial revolution as a historical moment in modern clothing culture through documental study. Historian's point of view and method of studying are important when we investigate the clothing phenomenon. Although culture phenomenon of industrial revolution has been evaluated usually through socialogical aspect, studying for clothing culture phenomenon must be carried out on aethetical as well as well as sociological aspect, on account of dualism of clothing, as it is social and artistic nature. In 19th century, there were technical improvement, changing patterns of production, changing social relation and beginning of mass culture. At the same time clothing culture phenomenon was changed in relation to modern capitalistic society. The findings of the study could be summarized as follows. 1. Technical improvement in textile industry and fitting process brought about mechanization of clothing industry. 2. Appearance of popular clothing culture made it easy to spread to various classes of society. 3. Development of transportation system and communication channel made it internationalization of western clothing. 4. Recognition of importance in functional style of clothing. 5. The pursuit of modern aesthetics made rapid changing mode of clothing. Above distinctive features of modern clothing culture were derived from by-product of machinary culture, mass culture, internationalism, rapidly changing mode of various culture during industrial revolution. Industrial revolution was a change of the material world as well as in industry owing to machine advent, then the culture part that displayed directly these changes was the plastic arts of living that mould the material. The problem of clothing construction caused by industrial revolution was solved by pursuing the functional aesthetics. Clothing phenomenon as a process of value transfer participates mass culture in closs relation to general change of various culture caused by industrial revolution. Therefore western clothing gained the qualities of modern culture, condensed as function, and popularity in the process of modernization.

The fourth industrial revolution will greatly contribute to the entry of objects into an intelligent society through technologies such as big data and an artificial intelligence. Through the revolution, we were able to understand human behavior and awareness, and through the use of an artificial intelligence, we established ourselves as a key tool in various fields such as medicine and science. However, the fourth industrial revolution has a negative side with a positive future. In this study, an analysis was conducted using text mining techniques based on unstructured big data collected through social media. We wanted to look at keywords related to the fourth industrial revolution by year (2016, 2017 and 2018) and understand the meaning of each keyword. In addition, we understood how the keywords related to the Fourth Industrial Revolution changed with the change of the year and wanted to use R to conduct a Keyword Analysis to identify the recognition flow closely related to the Fourth Industrial Revolution through the keyword flow associated with the Fourth Industrial Revolution. Finally, people's perceptions of the fourth industrial revolution were identified by looking at the positive and negative feelings related to the fourth industrial revolution by year. The analysis showed that negative opinions were declining year after year, with more positive outlook and future.

This study aims to examine the future image of the fashion industry according to the level of consumer knowledge and anxiety about the 4th industrial revolution. An online survey was carried out from March 13 to 23, 2018. A total of 698 consumers participated in the survey. The results of the study are as follows. The consumer knowledge level about the 4th industrial revolution was 10.2% for the first recognition, 48.3% for the term recognition, and 41.5% for the content understanding. The level of consumer anxiety about the 4th industrial revolution was 36.5% lower than average and 63.5% higher than the average. An ANOVA was conducted to confirm the anxiety according to the knowledge level of the 4th industrial revolution. The results revealed that consumers with higher knowledge level felt more anxiety than consumers with a lower level of knowledge. Consumer's knowledge level about the 4th industrial revolution did not affect the future image of fashion industry and individual phases of the fashion industry. Consumer's anxiety level about the 4th industrial revolution had a partial influence on the future image of the fashion industry and on each phase of the fashion industry. In the midstream and downstream areas of the fashion industry, significant differences were observed in the future image according to the level of anxiety.

Ein Schlagwort "die Vierte Industrielle Revolution" ist mehrdeutig und sehr unterschiedlich verstanden. Die Fragestellung, was die wesentlichen und allgemein anerkannten Elemente der "vierten industriellen Revolution", bezieht sich bisher auf neue Technologie oder Produkten wie $K{\ddot{u}}nstliche$ Intelligenz(K.I), autonomes Fahren, Internet der Dinge(IdD), 3D-Drucker usw. Unter einem historischen Gesichtspunkt bzw. der Geschichte der Industiriellen Revolution gibt es jedoch eine $Parallelit{\ddot{a}}t$ der rechtlichen Fragen, bsw. die Gefahrenabwehr, technische Kodifikation, Selbstregulierung, Internationalisierung des Technikrechts. Der Versuch, die Vierte Industrielle Revolution nur mit den neuen Technologie oder Produkten zu verstehen, kann nicht die Differenzierung zwischen jeden Stufen der industriellen Revolution konsequent $erkl{\ddot{a}}ren$. Dass die rechtliche Fragen der Vierten Industriellen Revolution angemessen behandelt, verlangt $zun{\ddot{a}}chst$ einen $Schl{\ddot{u}}sselbegriff$. Die vorliegende Arbeit setzt Digitalisierung als $Schl{\ddot{u}}sselbegriff$ voraus. Mit diesem $Schl{\ddot{u}}sselbegriff$ beleuchtet hier die Herausforderung des Verwaltungsrechts in der Zeitwende, wie die $Anpassungsf{\ddot{a}}higkeit$ und $Steuerungsf{\ddot{a}}higkeit$ des Rechts.

In this research we analyze Sun Wen's revolution education from the perspective of chinese nationalism. Sun Wen instigated the revolution of 1911 and established the first Chinese republican government; his "three people's principles" played an important role in modern Chinese politics. Sun Wen tried to remind the people and make them conscious of their sovereignty through education. Critical of then-the feudalistic education, Sun Wen incorporated Western-modern education in to his philosophy of education, which then provided theoretical framework of the Chinese revolution. At the core of it was the so-called "advanced education", based on Chinese nationalism, which encourages people to fight for independence as well as national prosperity and defense. The advanced education consisted of "proclaim education" and "constructive education". The proclaim education was a means of disseminating revolutionary ideas through an armed struggle against Ching dynasty; the goal was to encourage people to participate actively. Constructive education could be divided into two periods, namely the period of pre-republic of China and post-republic of China; the aim and process of education in the former period was to "wipe out" the Manchu people of the Qing dynasty while in the latter, to build a country predicated on Chinese nationalism, which was hostile towards the Qing dynasty and any other thoughts that do not accord with it. The main purpose of revolution education was to inspire Sinocentrism and to solidify the country of the Chinese people. Ultimately, Sun Wen's philosophy of revolution education provided foundation for the construction of a country of the Chinese people in which inspirational writing for the welfare of the people, loyalty to country, and public service are realized.
