By researching Western equestrian clothing, this study investigated the process in which styles of menswear are introduced into women's sportswear. In addition to women's equestrian clothing shown in paintings and illustrations kept in overseas museums, this study also analyzed books addressing 200 years of Western dress style history, from the late $17^{th}$ century to the $19^{th}$ century. The analysis data present the design characteristics of women's equestrian clothing according to different periods. A total of 21 works were used as research data: two from periods prior to the $17^{th}$ century, three from the $17^{th}$ century, ten from the $18^{th}$ century, and six from the $19^{th}$ century. The research results show that items of trendy menswear were commonly used in women's equestrian clothing during the late $17^{th}$ century - to be specific, in all forms of clothing worn on the upper body, including coat and cravat, tricomhat, and accessories. Women's equestrian clothing after the $18^{th}$ century took the form of menswear. However, the uniform was also generally worn with a fitted, tailored redingote on top of the robe, along with pants. In the $19^{th}$ century, women's equestrian clothing became longer in length, like men's styles. The uniform gradually lost volume, and the jacket became shorter and narrower. In addition, the drawers were replaced with pants that came down to the ankles, which were similar to men's trousers. Breeches also became knee - length, thus following the style of menswear. These results show that women's equestrian clothing, worn during horseback riding, a sport previously enjoyed by Western aristocrats, were similar to what men wore. Also, in contrast to the distinct differences seen between men's and women's daily clothing, the equestrian uniforms of women showed a tendency to follow the clothing style of men.

Furthermore, various kinds of sophisticated stitching including old flat felled seam, decorative saddle stitching and buttonhole stitch, clothing made roughly as a shroud and fabric attached on the clothing were also observed. We may not have many opportunities to understand the change of clothing in Korea from mid 16th century to mid 17th century through the clothing of father-in-law and daughter-in-law in a family. As a result, we will be able to understand the features of sewing in a family and from the 16th century to the 17th century.

21th century is a era of new pandemic. We are facing a new challenge and need a new way of approach. But eastern medicine and western medicine is clinging to their own way and have no intention to hear other one's opinion. Before the invention of the vaccination, smallpox has always been a major problem. Intellectuals in every country tried their best to find the treatment for the smallpox, and for Europian, didn't hesitate to borrow some knowledge of the pagon. Romans adopted the Galens concept, running away from the epidemic lesion. Christianity made smallpox Saints, and later adopted Razes heat therapy. But in the 17th century, these methods didn't turn out well, so they needed a new way of approach. By this movement, they had adopted the Chinese inoculation concept and invented a vaccination, By studying the effort of the Europian intellectuals who had tried their best to find the treatment for the smallpox until 17th century, we might get a glimps of wisdom which they had shown us. By this paper we can feel the passion to learn new techniques and their open mind and courage, which might be also needed in the 21th century, era of new pandemic.

Most of the studies on Yangban Houses dealt with the existing houses which were constructed, in most part, after the 17th century. Therefore it is important to identify the actual process of change from before the 17th century which is critical in understanding the history of residential architecture of the Chosun Dynasty. This study aims to clarify that the architectural condition after the 17th century is the result of the major change in sound the 16th century, and the prime motivation of that change was initiated by the family ritual which become very important social and idealogical base of the change. To be able to practice the family ritual, the spatial arrangement had to be changed, Man's quarter had to be enlarged, which a stone-floored room was added on one side of the centural wooden floor of the lady's quarter. Also, family shrine was erected on eastern side of the site. Thus, unless the major change in the 16th century, which was caused by the practice of family ritual, is understood, the study of historical background of Yangban houses can never be complete.

The economic decline coincided with the crooked political path of Spanish monarchy that has been on an almost permanent state of war. The Spanish empire was divided and consequently, general impoverishment spread throughout the whole country quickly. Nevertheless Spanish culture reached the climax, especially in the field of painting. Spanish paintings of 17th century are basically religious based on concept of Baroque, whose theme is usually the immaculate conception or mysterious figures of saints. Velaquez, Mrillo, and Ribera are the main painters who represented the trend of this time. Despite having fame as religious court painters, they painted subjects from low society such as beggars in rags, dwarves, jesters, or the poor child. They reflected an optimistic expression and an awe for human being in their paintings greatly. In this paper, we are dealing with three main representative painters of Baroque era whose theme was a picaresque character. This character was one of the axes that coexisted with royals and nobles in 17th century of Spain. The art works that are dealt in this paper serve as materials for historial values and through them we can observe the atmosphere of decline that dominated Spain of the time.

This article is a follow-up on the concept of philosopher/writer and its transformation in the Age of Enlightenment - 1. the dictionary meaning of the term 'philosopher/writer' and the origins of 'literary fields' of the Enlightenment era. In this article, we analyzed changes in the literary field in the late $17^{th}$ century after the expansion of the publishing market. We examined the conflict surrounding philosophers' identifying between modern and traditional philosophers. We have validated that the formation of new readers has made traditional philosophers more sensitive to the 'horizon of expectations' of readers. Some biographical works are also one of our concern. By the end of the $17^{th}$ century, philosophers and writers suddenly became objects of biographical works unlike in the past. Through our research, we found that readers have sought the arrival of a new hero, a great philosopher or a great writer, that will lead a new era, and due to this anticipation, it has led to the publication of biographical works. In this process, we have revealed conceptual changes about authors, writers, philosophers, and so on. In the next article, we will continue advanced discussion on the concept of philosopher/writer.
