Depression is a major mood disorder. Abnormal expression of glial glutamate transporter-1 (GLT-1) is associated with depression. Schisantherin B (STB) is one bioactive of lignans isolated from Schisandra chinensis (Turcz.) Baill which has been commonly used as a traditional herbal medicine for thousands of years. This paper was designed to investigate the effects of STB on depressive mice induced by forced swimming test (FST). Additionally, we also assessed the impairment of FST on cognitive function in mice with different ages. FST and open field test (OFT) were used for assessing depressive symptoms, and Y-maze was used for evaluating cognition processes. Our study showed that STB acting as an antidepressant, which increased GLT-1 levels by promoting PI3K/AKT/mTOR pathway. Although the damage is reversible, short-term learning and memory impairment caused by FST test is more serious in the aged mice, and STB also exerts cognition improvement ability in the meanwhile. Our findings suggested that STB might be a promising therapeutic agent of depression by regulating the GLT-1 restoration as well as activating PI3K/AKT/mTOR pathway.

Background: Ginseng (the roots of Panax ginseng Meyer) is a well-known traditional Oriental medicine and is now widely used as a health food. It contains several types of ginsenosides, which are considered the major active medicinal components of ginseng. It has recently been reported that the qualitative and quantitative properties of ginsenosides found in ginseng may differ, depending on cultivation regions, ages, species, and so on. Therefore, it is necessary to study these variations with respect to cultivation ages and regions. Methods: In this study, 3-6-yr-old roots of P. ginseng were collected from three different cultivation regions. The contents of five ginsenosides (Rb1, Rd, Rc, Re, and Rgl) were measured by rapid resolution liquid chromatography coupled with quadruple-time-of-flight mass spectrometry. The Kruskal-Wallis Rank sum test and multiple t test were used for comparative analysis of the data to evaluate the dynamic changes in the accumulation of these ginsenosides affected by cultivation regions and ages. Results: The content and composition of ginsenosides varied significantly among specimens collected from different cultivation regions and having different cultivation ages. For all samples, the content of Rg1 and Re ginsenosides increases with age and this rate of increase is different for each sample. The contents of Rb1, Rc, and Rd varied with cultivation ages in samples from different cultivation regions; especially, Rb1 from a 6-yr-old root showed approximately twofold variation among the samples from three cultivation regions. Furthermore, the content of Rb1 highly correlated with that of Rd (r = 0.89 across all locations and ages). Conclusion: In our study, only the contents of ginsenosides Rg1 and Re were affected by the root age. Ginsenosides Rb1, Rc, and Rd varied widely with ages in samples from different cultivation regions.

Ultrasonic waves provide a non-destructive and sensitive way to monitor the concrete hydration. However, limited works are reported to monitor the evolution of the mechanical parameter at early ages. In this study, modified piezoelectric aggregates are embedded inside a concrete beam to excite and receive primary waves. A hydration index, namely, the variation of ultrasonic waveform (VUW) is developed to characterize the variation of the transmitted waves during the hydration process. The recorded hydration indices are compared with the compressive strength measured by destructive test at different ages. The results show that the VUW is closer to the compressive strength than the other two traditional hydration indices, ultrasonic velocity and wave packet energy. The proposed VUW provides a simple and accurate way to monitor the concrete hydration at early ages.

purpose of this study was to trace historically the causes of the visual inconsistency of seXual ilT'age in dress with versatile perspectives. For this purpose, theoretical studies about the concepts of sexuality in dress were precceded. To trace the factors of the visual inconsistency of sexual image in dress, historical studies from ancient Egypt to modern ages were done. And then, the factors of the visual inconsist\ulcornerency of sexual image in dress were identified. The synthetic results were as follows; L The visual inconsistency of sexual image in dress shows the phenomena that men introduce the traditional feminine image in dress (ex. X silhouette, skirts), whereas women do the traditional masculine image (ex. Y silhouette, pants), which arouse androgynous image in appearance. And, it also indicates that men or women wear the dress excluded the traditional masculine image as well as the traditional feminine image, which arouse neutral image in appearance. 2. The visual inconsistency of sexual image in dress have been existed historically, from Egypt to modern ages. 3. The visual inconsistency of sexual image III dress was caus~d by various factors as follows; First, ideal beauty of the times which did not distinguish between masculinity and femininity resulted in the visual inconsistency of sexual image in dress. Second, as a means of seeking pleasure, the visual inconsistency of sexual image in dress was used. Third, as a means of expressing ideology, the visual inconsistency of sexual image in dress was selected. Forth,in religious meaning,the visual inconsistency ofl sexual image in dress was appeared.

Korea huts been dramatically changed during the last century in many aspect of society, with the introduction of western culture in the beginning of 20th century. This study aims at understanding the changes in our traditional culture shown by costume as well as examining the aspects of the changes of traditional clothing according to age, by comparing the differences of our traditional dress Hanbok between ear1y and the late of the 20th century. Analysis of photographs showing Hanbok of both ages was used. 155 photographs of people wearing traditional Hanbok in the beginning of the 20th century were collected from the photo collection books portraying various living conditions of common people at that time. 748 Photographs of Hanbok worm today were obtained by taking pictures of various occasions like wedding ceremonies in 5 big cities during 1997. The process of analysis consists of 3 stages: setting standards, sorting, and grouping by positioning. The results showed that traditional Hanbok room in the early 20th century has maintained its basic silhouette and design during the century, but the methods of color coordination, ornamentation, construction have underdone many changes in detail. Consequently, traditional frame exits, but actually there are many variations of tradition produced by individual tastes and fashion trend. These changes show that continuing influx of the western culture which has made enormous social changes in Korea had an influence even on Hanbok.
