The Purpose of this article is to study the excavated women's costume of the Joseon Dynasty, and to help identify the period of those costumes with the time of the burial unknown. The excavated women's costume is concentrated in 16th to 17th century, and the reason is due to the method of the burial. The characteristics of costumes from each period is as follows. The special features about 15th century costumes are the women's Dan-ryeong(round-collared jacket), Dae-gum style shirt(shirt with the squared collar facing each other), and skirt with horizontal dart. The 16th century costumes are the women's Dan-ryeong, wide Jegori with various length, skirt with horizontal dart, skirt with its hem folded, and pants with shoulder strap. In the 17th century, the formal dress changes to Won-sam from Dan-ryeong. The collar changes from the squared shape to the cut Dang-ko collar, and the skirt with its hem folded is not seen after the early 17th century. The long jacket changes to Dang-ui and gets settled, and the clothes becomes smaller and tighter. In the 18th century, the women's formal dress gets settled to Won-sam and Dang-ui, and the pants with shoulder strap is no longer seen. Jegori becomes shorter and smaller compared to those from the 17th century, and again gets wider and bigger in the late 18th century, and it leads to the change of making a big sized shroud.

Resveratrol is a naturally occurring stilbene which is safe and well-described compound with a potent anti-inflammatory activity. Recent studies suggested that resveratrol suppressed various inflammation mediated diseases such as asthma, chronic colitis, rheumatoid arthritis, and type 1 diabetes. These studies indicated that resveratrol might directly modulate $CD4^+$ helper T cells (Th cells)-mediated immune responses. However, it is not fully elucidated whether resveratrol directly regulates $CD4^+$ Th cell activation and differentiation. In the present study, $CD4^+$ Th cells were purified from C57BL/6 and treated with various concentrations of resveratrol. We found that resveratrol directly suppressed $CD4^+$ Th cells activation, leading to a defect in T cell proliferation. When $CD4^+$ Th cells were treated with resveratrol, cytokine production was also significantly reduced in a dose dependent manner. In accordance with these results, resveratrol even inhibited $CD4^+$ Th cells differentiation into Th1, Th2 or Th17, which produces IFN-${\gamma}$, IL-4 or IL-17 respectively. We also found that resveratrol could induce apoptosis of $CD4^+$ T cells at a high concentration. Our data demonstrated that resveratrol inhibited directly $CD4^+$ Th cells activation and differentiation. It suggests that resveratrol could be an efficient therapeutic strategy for autoimmune diseases in which $CD4^+$ Th cells play a critical role.

A hat is a general term for what human beings wear on their heads in order to protect them from the cold or heat, to be used for ornament, or to symbolize social position. A hat represents the position of a man who wears it, attitude toward the society, and faith for a religion for males. Since men's hats can create their image and uniqueness in casual wear from current fashion items, they are proposed as a fashion accessory item of designers each season. The purpose of this study is to review hats, which are part of costume, in a more analytic method. The research range of this study is hats for men in the upper class in the 17th to 18th centuries from the history of costume when diverse periodic and characteristic costume changes occurred. In the 17th to 18th centuries in the middle of the Chosun Dynasty, changes in costume occurred as the feudal society of the dynasty had been dissolved since the Japanese invasion in 1592. Political power was established in France as the Baroque Age began in the 17th century. Since European costume, especially women's costume led fashion in France, the country represented the age better than any other countries. Aristocratic costume in the Rococo Age of the 18th century was changed to completely different shape of costume after the French Revolution. In this regard, this age was deemed to be the most appropriate for the comparison or costume. Another purpose of this study is to review the common and different features of periodic factors that affect changes in costume by researching the hats of the two countries in the same age in order to understand relation between periodic characteristics and costume throughout history of costume.

To determine alteration of immune responses during visceral larva migrans (VLM) caused by Toxascaris leonina at several time points, we experimentally infected mice with embryonated eggs of T. leonina and measured T-helper (Th) cell-related serial cytokine production after infection. At day 5 post infection (PI), most larvae were detected from the lungs, spleen, intestine, and muscle. Expression of thymic stromal lymphopoietin (TSLP) and CCL11 (eotaxin) showed a significant increase in most infected organs, except the intestine. However, expression of the CXCL1 (Gro-${\alpha}$) gene was most highly enhanced in the intestine at day 14 PI. Th1-related cytokine secretion of splenocytes showed increases at day 28 PI, and the level showed a decrease at day 42 PI. Th2-related cytokine secretion of splenocytes also showed an increase after infection; in particular, IL-5 level showed a significant increase at day 14 PI, and the level showed a decrease at day 28 PI. However, levels of Th17-related cytokines, IL-6 and IL-17A, showed gradual increases until day 42 PI. In conclusion, Th1, Th2, and Th17-related cytokine production might be important in immune responses against T. leonina VLM in experimental mice.

Lanthanum oxide was introduced to molybdenum powder by liquid-liquid doping and liquid-solid doping respectively. Mo alloys were prepared by powder metallurgy technology. The size distribution and feature of dopant particles and the fractographs of Mo alloys were investigated by TEM and SEM respectively. The results indicated that liquid-liquid doping method is favorable for refining and dispersing $La_2O_3$ particles uniformly in matrix. Fracture toughness of Mo alloys prepared by liquid-liquid doping showed better results than that of liquid-solid doping. Furthermore, the influences of the size distribution of $La_2O_3$ on properties of Mo alloys was discussed by dislocation pile-up theory.

This paper tried to investigate the features of French garden pavillons (jardin pavillons) in the 17th and 18th centuries, in which the royal built them, publicly enjoying culture or privately having a refuge. The scope of the garden pavilions covered those associated with a pleasure place that accommodated performances, dancing, and dinners. They included not only rustic, Chinese, Turkish and Gothic pavilions but also grottos, nymphaeums, and artificial ruins built for banquets and festivals. This paper identified the features of the 17th and 18th century French garden pavilions as follows: Those pavilions firstly established French Neoclassicism, secondly applied the techniques of pastiche, thirdly reflected women's influence, and lastly revealed the short cycles of their vicissitudes. In conclusion this study, with the summary of the main text, explained the influence of the French pavilions on Europe and America.

This study shows the badge system for military officials of Joseon dynasty. The badge system for military officials of the 15th century consists of rank badges with tiger and leopard for the first and second ranks and rank badges with bear for the third rank. According to the code of laws, military officials are supposed to wear the rank badges with four different kinds of animals in Joseon dynasty. However, the badge system shown in the code of laws sometimes does not match with the badges in practices. Based on the literature, remaining badges and the badges in portraits, six different kinds of badges with animals are found : First, rank badges with tiger and leopard were used until the late 16th century. Second, rank badges with tiger were found in the period between the early 17th century and the latter 18th century. Third, rank badges with Haechi were found in the early 17th century. Fourth, rank badges with lions can be found in remains of the mid 17th century, the literature and the portrait of the late 18th century. Finally, the rank badges with double leopards or with single leopard were found from a portrait dated the late of 18th century to the last period of Joseon dynasty.

CD28/T cell receptor ligation activates the NF-${\kappa}B$ signaling cascade during CD4 T cell activation. NF-${\kappa}B$ activation is required for cytokine gene expression and activated T cell survival and proliferation. Recently, many reports showed that NF-${\kappa}B$ activation is also involved in T helper (Th) cell differentiation including Th17 cell differentiation. In this review, we discuss the current literature on NF-${\kappa}B$ activation pathway and its effect on Th17 cell differentiation.

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.
