In this text, the author examines the aspects and characteristics of the three forms that were created and enjoyed when the upper-class nobles of Japan "combined(混淆)" waka(和歌) and Chinese poetry(漢詩) between the 10th and 17th centuries. The three forms are the "Collection of Japanese and Chinese poems for singing"(和漢朗詠), "A collection of Japanese and Chinese poems" (詩歌合), and the "Renku renga"(聯句連歌). "Collection of Japanese and Chinese poems for singing" appeared in the 10th century, "A collection of Japanese and Chinese poems" appeared in the 12th century, "Renku renga" appeared in the 14th century, and all three continued to influence the history of Japanese literature after that time. As the combination of literary Japanese and Chinese progressed, the gap between waka and Chinese poetry decreased until they finally combined to create a single work. That is, waka and Chinese poetry converged in one place in multiple ways: as a work that was appropriate to be recited("Collection of Japanese and Chinese poems for singing"), facing each other work against work in a competition("A collection of Japanese and Chinese poems"), and, in the end, they reached the point where they were interchangeable as lines making up long poems(長詩)("Renku renga"). The combination of literary Japanese and Chinese can be said to be the Japanese version of the common movement in East Asian literary history during the Middle Ages to make songs from one's own language flawless in Chinese poetry. Meanwhile, by examining the status changes that appeared as Chinese poetry paralleled, fought with, replaced, and combined with waka, we can find clues to explain the attitudes of the Japanese people on Chinese poetry during the period when the three forms existed, as well as the characteristics of Japanese Chinese poetry that appeared in response to that. The preferences not of "myself" but of the "audience," content and expressions that revere the period rather than the inner self of the poet, and the fact that it is a means for enjoyable pleasure rather than having the original characteristics of lyrical poetry for self-expression are all characteristics of Chinese poetry in Japan during the early and late Middle Ages period. These characteristics can be said to be the current that flows in the underbelly of the history of Chinese literature in Japan. This author believes that the key to discussing the history of Chinese literature in Japan during the Middle Ages period from the perspective of East Asian literary history can be found here.

This study was carried out to research the locations and comprehensive functions of Chinese unique Banwoldang(half-moon shaped pond) appeared at the traditional Chinese villages. Based on the research, the time of Banwoldang being introduced into Chinese traditional culture could date back to Yuan Dynasty and villages that have Banwoldang mainly distributed in the south of the Yangtze River of China where wealthy and high class have lived. Bamwoldangs were mostly built at the front of the village clan halls for the prosperity of the whole clan, The main reason of Banwoldang construction was to complete Feng Shui functions and its goal from the point of Feng Shui in Chinese ancient villages was replenishing the power of location, including increasing the probability of passing the imperial examination for villagers, multiplying riches, minimizing the fire accident and perfecting the geomantic pattern 'leaning against the hill and facing the water(背山臨水)' of villages. Other functions of Banwoldang were found as the place for the community meeting, fish farming and protection of village from enemy. In this research, the reasons of Banwoldang location and values of its various functions were found. But Banwoldang is disappearing rapidly at the Chinese modern villages because there is no interest in traditional culture. Banwoldang is one of unique elements of Chinese culture that must be preserved, so its meaning and value should be lasted well as the Chinese traditional cultures.

In this study, we aim to investigate the precise alterations in the gut microbiota during the onset and advancement of diabetic nephropathy (DN) and examine the impact of Ruminococcus gnavus (R. gnavus) on DN. Eight-week-old male KK-Ay mice were administered antibiotic cocktails for a duration of two weeks, followed by oral administration of R. gnavus for an additional eight weeks. Our study revealed significant changes in the gut microbiota during both the initiation and progression of DN. Specifically, we observed a notable increase in the abundance of Clostridia at the class level, higher levels of Lachnospirales and Oscillospirales at the order level, and a marked decrease in Clostridia_UCG-014 in DN group. Additionally, there was a significant increase in the abundance of Lachnospiraceae, Oscillospiraceae, and Ruminococcaceae at the family level. Moreover, oral administration of R. gnavus effectively aggravated kidney pathology in DN mice, accompanied by elevated levels of urea nitrogen (UN), creatinine (Cr), and urine protein. Furthermore, R. gnavus administration resulted in down-regulation of tight junction proteins such as Claudin-1, Occludin, and ZO-1, as well as increased levels of uremic toxins in urine and serum samples. Additionally, our study demonstrated that orally administered R. gnavus up-regulated the expression of inflammatory factors, including nucleotide-binding oligomerization domain-like receptor pyrin domain-containing protein 3 (NLRP3) and Interleukin (IL)-6. These changes indicated the involvement of the gut-kidney axis in DN, and R. gnavus may worsen diabetic nephropathy by affecting uremic toxin levels and promoting inflammation in DN.

The control of underactuated mechanical system is very complex for the loss of its control inputs. The model of underactuated mechanical systems in a potential field is built with Lagrangian method and its structural properties are analyzed in detail. A genetic algorithm (GA)based stable control approach is proposed for the class of under actuated mechanical systems. The Lyapunov stability theory and system properties are utilized to guarantee the system stability to its equilibrium. The real-valued GA is used to adjust the controller parameters to improve the system performance. This approach is applied to the underactuated double-pendulum-type overhead crane and the simulation results illustrate the complex system dynamics and the validity of the proposed control algorithm.

The emergence of coffee shops and other public spaces in modern Shanghai shows the appearance of the "mass" centered on the middle class. Furthermore, we can further explore the different development paths of the publicity of modern Chinese urban society. The emergence of new public leisure spaces, such as cafes, provides a model of modern life style and a stage of daily publicity for the middle class in Shanghai. With the convenience provided by this kind of public space, people are able to clean up their old opinions and be better at accepting new ideas. A more sensitive and flexible public opinion of Enlightenment has gradually formed in urban life.

A fundamental trend of processor architecture evolving towards exaflops is fast increasing floating point performance (so-called "free" flops) accompanied by much slowly increasing memory and network bandwidth. In order to fully enjoy the "free" flops, a numerical algorithm of PDEs should request more flops per byte or increase arithmetic intensity. A meshfree/GFEM approximation can be the class of the algorithm. It is shown in a GFEM without extra dof that the kind of approximation takes advantages of the high performance of manycore GPUs by a high accuracy of approximation; the "expensive" method is found to be reversely hardware-efficient on the emerging architecture of manycore.

We describe here the cloning and characterization of a cDNA encoding the glutathione S-transferase (GST) from the bumblebee Bombus ignitus. The Delta-class B. ignitus GST (BiGSTD) gene spans 1668 bp and consists of four introns and five exons that encode 216 amino acid residues with a calculated molecular weight of approximately 24561 Da and a pI of 8.03. The N-terminal domain of BiGSTD has a conserved Ser residue, as well as conserved Lys, Pro, Glu, Ser and Tyr residues that are involved in the GSH-binding site of GST. The BiGSTD showed 60% protein sequence identity to the Bombyx mori GSTT1, 58% to Musca domestica GST, 57% to Drosophila melanogaster GST, and 55% to Anopheles gambiae GST1. BiGSTD was close to the insect-specific Delta class of GSTs in a phylogenetic tree. Northern blot analysis showed that BiGSTD is highly expressed in the fat body and midgut, and less so in the muscles of B. ignitus worker bees.

Objectives : The purpose of this paper is to clarify the social characteristics of the authors of Huangdi Neijing such as status, class, and political ideology. Methods : We analyze the Neijing text and the social order and historical situations in the Han dynasty. Results : Some authors of the Neijing were the local medical officers whose salary was 100~400shi. Their positions were medical craftsmen(yigong) or chief medical craftsmen(yigongchang). They would have published the Neijing after the administrative reforms(146-145 BCE) that began after the suppression of the Rebellion of the Seven Kingdoms. The bureaucrat yigong(chang) would have expected to participate in the public health policy of the empire or kingdom as an acupuncture expert. They would have also expected to contribute to the welfare and health of the privileged intellectual group and the public, hoping to ascend in status and class. Conclusions : By investigating the social characteristics of the authors who composed the Neijing, its various aspects would be newly understood.
