Building buffer zone space is not only one of essential approaches for better mental quality of interior building space, but also an important factor that may influence interior thermal comfort and energy consumption. This study aims to analyze regulative advantages of buffer zone to the surrounding functional spaces. Based on a fieldwork test in a typical office building in cold climate zone in Beijing,China,the monitor data show interior physical performance in the Winter. The research selects two types of different buffer zones in the same building. One is a south-faced greenhouse which has large dimension with plenty of vegetation,and the other is a simple atrium in the middle of five floor building with mount of skylights. The factors and their influence to surrounding functional spaces and the whole building are found out from the comparisons of collected data by floor to floor monitor test on both buffer zones at the same time. The comparisons of two types of buffer zones conclude that the greenhouse is more effective to air quality regulation but not so clearly wellperformed to thermal buffering as expected due to the dominate active central heating in the Winter. This fieldwork test results for building performance can be helpful for both architects and engineers in the early phase of sustainable design.

Assessing Forest Cover Distribution, Species Diversity, and Richness of the buffer zone for Strategic Forest Management Planning for Nimule National Park, South Sudan

Natural forest ecosystems play an essential role in the conservation of biodiversity of many plants and animals by providing them with habitat and suitable environments. Studies have shown that biodiversity-protected areas reduce the loss and degradation of natural habitats to various wild species of plants. This study examined the forest resources in five subzones by conducting tree/shrub species inventory to be able to develop an effective forest management plan for the buffer zone Forest Reserve for the sustainable conservation of flora and fauna of Nimule National Park. This is with the view to identify the main tree and shrub species;assess the composition, distribution, and abundance of various tree/shrub species;to determine the species diversity as well as the richness of these areas in terms of growth and performance where DBH and heights of trees/shrubs in the circular sample plots were measured. The results revealed the overall mean DBH and H of 13.83 cm and 6.61 m respectively. The highest number of trees was obtained in subzone B followed by D, while the least were found in subzone A. The overall mean tree/shrub density was 0.83 tons/ha. The mean total basal area and volume per hectare were 3252.74 m2/ha and 46,540.82 m3/ha respectively. The overall species abundance and distribution indicate Combretum spp, Cedrella spp., Grewia mollis, Acacia Sieberiana, Ziziphus abysinica, and Acacia seyal were the most dominant species, with over 12 species richness at the deposition side of the River Nile, 13 species at the western side of the Nile, the Administration site shows only 7 species, the lowland of Mt. Gordon show over 14 different species, whereas over 10 species were found on the top of Mt. Gordon. The overall mean diversity indices and evenness of H’, D, and E depicted 2.507, 0.871, and 0.840 respectively. These results yielded are relatively moderate. Therefore, conservation efforts are very necessary to improve and maintain the

A Bond Pricing Model with Credit Migration Risk:Different Upgrade and Downgrade Thresholds

引用

Acta Mathematicae Applicatae Sinica 2023年第3期39卷 765-777页

作者： Jin LIANG Yang LIN School of Mathematical Sciences Tongji UniversityShanghai 200092China

In this paper, a new corporate bond pricing model with credit migration risk is proposed. This model sets different thresholds for the rising or falling of credit ratings, which forms a buffer zone that could reduce the frequency of credit rating changes. Mathematically, this model is a system of partial differential equations with overlapping area. The existence, uniqueness, regularity and asymptotic behavior of the solution are obtained. Furthermore, a numerical scheme and its stability, convergence and accuracy are discussed in detail. Calibration and analysis of the parameters are also suggested.

斯里兰卡东部省2004年海啸灾难幸存者的聚居地安置

斯里兰卡东部省2004年海啸灾难幸存者的聚居地安置

The 2004-Tsunami disaster in Sri Lanka is one of the most significant landmarks in the history of the country. Restoration of the normal life of the disaster survivors is the upper most concern among the other post-disaster needs. The government's country wide post-tsunami declaration of a lengthy buffer zone as No-Living zone has added further more to the challenges of bringing the affected people to their normal life.Following the declaration, the literatures and the arguments on it have illustrated the confusion and hardship in the implementation of the declaration in the coast line of Sri Lanka in general. They argue that the declaration limits the social and spatial scope of the survivors' residency. It has banned the people to resettle in their former places within 200m from the seashore. Here the main issue is that either relocating the survivors miles away from their former places or resettling them in the same place where they lived before Tsunami.The main aim of our studies is to confirm the resettlement location for the survivors of the eastern coast line of Sri Lanka as this province has sustained the highest devastation in the disaster. By carefully investigating the geographical aspects such as socio-economy, politics, land, culture and environment of the Eastern Province, our studies justify the resettlement of the survivors rather than relocating them miles away from their former places. And in our studies, suggestions and recommendations are made with the view to utilizing the coastal zone in more sustainable ways in the future.
