Abstract ：
Existing graph systems focus mainly on the execution efficiency of the graph analysis tasks, often ignoring the importance and efficiency of time-evolving graph storage. However, to effectively mine the potential application values, an efficient storage system is important for time-evolving graphs whose storage requirement scales with the increasing number of snapshots. Storage cost and snapshot access speed are the two most important performance indicators for a time-evolving graph storage system, which are challenging for designers of such systems because they are conflicting goals. In this article, we address these challenges by proposing an efficient storage scheme for the large time-evolving graphs. We first design a Snapshot-level Data Deduplication (SLDD) strategy to eliminate the large number of repeated vertices and edges among the snapshots, and then a Structure-Changing Graph Representation (SCGR) to significantly improve the snapshot access speed. We implement an efficient time-evolving graph storage system, TgStore, based on this scheme to effectively store large-scale time-evolving graphs, aiming to efficiently support the time-evolving graph analysis tasks. Experimental results show that TgStore can obtain a high compression ratio of 43.03:1 when storing 100 snapshots of Twitter, while with an average snapshot access speedup of 16x. Efficient storage scheme enables TgStore to efficiently support time-evolving graph algorithms. For example, when executing the Pagerank algorithm on the time-evolving graph of Twitter, TgStore outperforms Graphone, a state-of-the-art time-evolving graph storage system, by 15.9x in algorithm execution speed and 1.45x in memory usage.

Abstract ：
Under the background of rapid aging in China, the security of the elderly in home care has become the focus of social attention. The present study takes the Hubin community of Ningde City as the case study area; and uses hierarchical regression analysis, structural equation model, and other methods to explore the influence path of the sense of security of the elderly in home care under the moderating effect of the intelligent monitoring system, and the subjective and objective demands for such equipment among the elderly. The results showed that compared with family care and social support, the influence of individual health on the sense of security of the elderly in home care was dominant. The intelligent monitoring system can play a negative moderating effect in the process of individual health directly affecting the sense of security of the elderly in home care, and indirectly improving the sense of security of the elderly in home care. Therefore, under the premise of paying attention to the individual health of the elderly at home, the reasonable application of the intelligent monitoring system and full play to its moderating effect is a practical way to improve the sense of security of the elderly in home care. In addition, the family and society should also pay more attention to the security of the elderly in home care, so as to promote the overall improvement of their sense of security.

Abstract ：
As the historical and contemporary values of Chinese traditional villages continue to emerge and the circumstances of the times change, their preservation has a lasting and far-reaching significance in promoting the revitalisation and sustainable development of China's countryside. However, rapid urbanization began after China's reform and opening up, and continuous urban expansion led to the rapid decline or even disappearance of these villages. Previous studies on village protection tend to focus on morphological studies from the perspective of individual units, and rarely discuss the influencing factors of spatial distribution. Therefore, there are certain deficiencies in revealing the distribution rules, which makes it difficult to fully carry out the protection work. The article reconstructs the traditional village system of Fujian Province, whose traditional villages cover both national and provincial historical and cultural villages and national and provincial traditional villages. The spatial distribution characteristics and influencing factors of traditional villages in Fujian Province were studied using 1,606 traditional villages of various levels as research objects. The results of the study show that: (1) the spatial distribution of traditional villages in Fujian Province is cohesive, with significant uneven distribution, and there are three high-density agglomerations and two sub-density agglomerations; (2) The spatial distribution shows a pattern of "large scattering, small concentration, more in mountainous areas and less in coastal areas"; (3) Topography, river systems, transportation and socio-economic conditions combine to influence the spatial distribution of traditional villages in Fujian Province, but the degree of influence varies. Physical and geographical conditions play a leading role in the distribution of traditional villages, and road traffic conditions and socio-economic conditions have a secondary impact on the distribution of traditional villages. There is an obvious agglomeration of traditional villages in the mountainous river areas, while there is a certain degree of negative correlation between road traffic conditions and socio-economic conditions and the number of traditional villages. (4) With the support of good policies and economic conditions, the protection and continuation of traditional villages can be promoted to a certain extent, and it is also conducive to the spread of local multicultural culture. Finally, corresponding policy recommendations are made for the conservation and sustainable development of traditional villages in Fujian Province.

Abstract ：
The territory space suitability evaluation is the basic work of performing a new round of territory spatial planning in China. Judging the supply and demand status of space resources by coupling land suitability evaluation and land expansion simulation, which has certain theoretical and practical significance for the formulation of territory spatial planning. The current technical framework of territory space suitability evaluation emphasizes current situation analysis and ignores trend research. This article discusses how to supplement the technical framework with territorial spatial development trend forecasting. Taking Jiangxi Province as the case area and county-level administrative districts as the research unit, using the coupled and supplemented technical framework, a coupled analysis was carried out on the spatial suitability evaluation of the planned area and construction land expansion simulation. The case study shows that the current suitable development areas are inconsistent with the future expansion areas of urban space. Therefore, it is difficult to reflect the dynamic changes in construction land only by dividing the urban space based on suitability evaluation. On this basis, coupling dynamic trend prediction helps to provide planners or decision-makers with a more vivid and intuitive reference, thereby enhancing the scientificity of territory spatial planning.
