  • It seems that Balhae(渤海) had built up its national power through the international relationship from the early years of an establishment of a dynasty. And the envoys that were sent with the official duties dressed up the official uniform for a diplomatic courtesy. Accordingly, this study will be considered about the official uniform in the early years of the Balhae era. The system of the official uniform of Balhae was classified into two form as the starting from $739\sim742$ A.D. The official uniform of the early years of the Balhae($698\sim739$ A.D.) was based on the costume of the three Kingdoms[三國時代], that is, Yu, Go(待), Jo-u-gwan(鳥羽冠). These results were available owing to the reasons that the Balhaehad succeeded the culture of Go-gu-ryo(高句麗), which was the basis for the development of Parhae's own culture, and the most of the governing group and the ruling class in Balhaewere the drifting people from Go-gu-ryo. After that, which the 3th King Mun(文王), acrepted the Tang's culture positively, assumed the reins of government ascended the throne and the brisk exchange with Tang(唐) by the envoys and Suk-wui(宿衛) were dispatched to Tang, the official uniform of the Balhaewas transformed into the system of Tang. This system was similar to that of Tang in point of using a four colors and the items as Danryeong(團領), Bokdu.

  • This study developed diagnostic system to understand the level of welfare cultural service and infrastructure in rural areas. The applicability was reviewed through the Delphi survey and the sample survey of 60 villages. The diagnostic indicators consist of three areas: the demand area, supply area, and delivery area. The demand area consists of 8 indicators, 25 indicators for welfare services and infrastructure (healthcare, social welfare) and 32 indicators for cultural services and infrastructure (culture, education, leisure sports). The service delivery area was divided into service supply area access and traffic accessibility (public transport use status and rural transport model status) by each indicator. A diagnostic system was applied to 60 villages. Services and infrastructure for rural welfare and culture were supplied more in the Si area than Gun area. The delivery area was easier to access the Gun area than Si area. In the case of traffic access, public transportation was more frequently used in the Si area than Gun area, and the rural transportation model was found to have a relatively large amount in the Gun area compared to Si area. The diagnosis system about services and infrastructure for rural welfare and culture will provide information necessary for establishment and decision making of regional development policy taking into account characteristics of rural areas in the future.

  • Despite many researches related with in-vitro culture of porcine spematogonial stem cells (SSCs), adherent culture system widely used has shown a limitation in the maintenance of porcine SSC self-renewal. Therefore, in order to overcome this obstacle, suspension culture, which is known to have numerous advantage over adherent culture, was applied to the culture of porcine SSCs. Porcine SSCs retrieved from neonatal testes were suspension-cultured for 5 days or 20 days, and characteristics of suspension-cultured porcine SSCs including proliferation, alkaline phosphatase (AP) activity, and self-renewal-specific gene expression were investigated and compared with those of adherent-cultured porcine SSCs. As the results, the suspension-cultured porcine SSCs showed entirely non-proliferative and significantly higher rate of AP-positive cells and expression of self-renewal-specific genes than the adherent-cultured porcine SSCs. In addition, long-term culture of porcine SSCs in suspension condition induced significant decrease in the yield of AP staining-positive cells on post-day 10 of culture. These results showed that suspension culture was inappropriate to culture porcine SSCs, because the culture of porcine SSCs in suspension condition didn't stimulate proliferation and maintain AP activity of porcine SSCs, regardless of culture periods.

  • Although monoculture methods have been remarkably useful due to their simplicity, they have serious limitation because of the different types of cells communication with each other in many physiological situations. We demonstrated levels of markers of endothelial dysfunction such as tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin-1$\beta$ (IL-1$\beta$) as well as stimulation of receptor of advanced glycation endproducts (AGEs) on monoand co-culture system such as only monocyte (THP-1) cultivation system, only endothelial cell (HUVEC) cultivation system, and co-cultivation system of THP-1 and HUVEC. The mRNA levels of TNF-$\alpha$ and IL-1$\beta$ on HUVEC increased by the co-culture with monocyte after 4 hr at 100 ${\mu}g/mL$ glyceraldehyde-AGE. The secreted protein contents into medium of TNF-$\alpha$ and IL-1$\beta$ increased after 8 hr approximately 2~2.5 times compared to mono-cultivation. In contrast, the mRNA level of receptor of AGE (RAGE) was relatively insensitive on the co-culture system. The mediators by which monocytes activate endothelial cell have not been fully elucidated. In this study we confirmed production of soluble cytokines such as TNF-$\alpha$ and IL-1$\beta$ by monocytes. Use of monocyte conditioned medium, which contains both cytokines, can activate endothelial cell.

  • Photoautotrophic micropropagation systems do not include sugar in the culture media. This characteristic provides advantages to scale up the micropropagation systems comparing photomixotrophic micropropagation systems. A closed, large-scale photoautotrophic micro-propagation for transplant production system has been developed at Chiba University, Japan. New concepts and technologies were adapted to produce high quality transplants at minimum usage of resources, and as scheduled. Newly developed software for production management was used to enhance the efficiency of the transplant production system. Currently, virus-free transplants of sweetpotato (Ipomoea batatas (L.) Lam.) are vegetatively propagated and produced under sterilized conditions in this system. This system can also be used for production of transplants of any other species including horticultural and woody plants with a minimum of modification.

  • This paper describes the design and trial development of a system that supports continuous hazard mapping by local residents in their daily life. We performed an interview survey to design our system in a model traditional town in Saga Prefecture, Japan. The results show that despite continued efforts, many practical problems remain and residents feel unsafe. Considering these results, we designed and developed a unique information and communication technology-based support system that contributes to community-based disaster prevention and reduction. The continuous resident participation and posting design are the core concept for our community-based approach. Our system continues to support making a hazard map by integrating the community-based hazard information. Local residents register information (disaster types, risk level, photographs, comments, positional information) about locations that could be dangerous in a disaster. In addition, our system enables information sharing through a Web server. We expect that this information sharing will allow local hazard information for each district to be used.

  • This paper is to explore the success factors of the online public grievance redressal system in the Nepal. It empirically tests the conceptual path model developed by DeLone and McLean which consists of six social perception variables with regard to citizen's intention to use the system. The estimates from 577 respondents support all the 13 hypotheses generated from D&L model. People's attitude and social norms are the two most important factors on the continuous usage of the system. It is suggested that the social factors are as much important as technological aspects when it comes to the e-government implementation. It is also suggested that the government should pay more attention to human factors in upgrading the design and development of e-grievance system in the foreseeable future.
