Cloud computing enables users to easily store their data and simply share data with others. Due to the security threats in an untrusted cloud, users are recommended to compute verification metadata, such as signatures, on their data to protect the integrity. Many mechanisms have been proposed to allow a public verifier to efficiently audit cloud data integrity without receiving the entire data from the cloud. However, to the best of our knowledge, none of them has considered about the efficiency of public verification on multi-owner data, where each block in data is signed by multiple owners. In this paper, we propose a novel public verification mechanism to audit the integrity of multi-owner data in an untrusted cloud by taking the advantage of multisignatures. With our mechanism, the verification time and storage overhead of signatures on multi-owner data in the cloud are independent with the number of owners. In addition, we demonstrate the security of our scheme with rigorous proofs. Compared to the straightforward extension of previous mechanisms, our mechanism shows a better performance in experiments.

Along with China's increasing share in global total $CO_2$ emissions, there is a necessity for China to shoulder large emission-mitigating responsibility. The appropriate allocation of $CO_2$ emission quotas can build up a solid foundation for future emissions trading. In views of originality, an optimized approach to determine $CO_2$ emissions allocation efficiency based on the zero sum gains data envelopment analysis (ZSG-DEA) method is proposed. This paper uses a non-radial ZSG-DEA model to allocate $CO_2$ emissions between different Chinese provinces by 2020 and treats $CO_2$ as the undesirable output variable. Through the calculation of efficiency allocation amounts of provincial $CO_2$ emissions, all provinces are on the ZSG-DEA efficiency frontier. The allocation results indicate that the cumulative optimal amounts of $CO_2$ emissions in 2020 were higher than the actual amounts in 13 provinces, and lower in other 17 provinces, and show that different provinces have to shoulder different mitigation burdens in terms of emission reduction.

Purpose Virtual communities change the way people communicate and share information. The purpose of this paper is to find how internet social capital and individual motivations influence the information sharing in virtual communities. This study considers the social capital theory, individual motivations, information sharing, and community promotion to construct a theoretical model. Design/methodology/approach Social capital focuses on three dimensions that include 6 factors: social interaction ties, centrality, shared language, shared vision, trust and reciprocity. Individual motivations include 2 factors: reputation and enjoy helping. To confirm the research model and the hypotheses, 426 effective questionnaires were used for the final analysis. Findings The result of data analysis demonstrates that social interaction ties, centrality, shared language, trust, and reciprocity were significant in affecting information sharing behaviors. However, reputation, enjoy helping, and shared vision does not appear to have a significant influence on information sharing behaviors. The information sharing was positively related to community promotion.

The China entered World Trade Oganization(WTO) last year, thus opening its border to more - and freer - trade. With its foreign trade rapidly expanding and with economic growth continuing at a substantial -rate, China will be the largest container traffic generating country in the world. In the light of this potential trade bonanza, regional ports in North-East Asia strive to gain a competitive-edge. The Port of Busan, the world's third largest container port, wants to capture a significant share of the china's container cargoes. In this circumstance, development strategies of the Port of Busan are suggested as follows. First, to cope with increasing volumes, the New Busan Port on Gaduk island should be constructed without failure. Second, it is necessary to add modernized high-performance gantry cranes and to train crane operators' skill. Third, it needs to apply Dwell Time- Sliding Scale System for transshipment cargoes. Fourth, it needs to develop the EDI network in terminal areas or adjacent hub ports to exchange trustworthy and satisfactory informations Fifth, port authority -needs to enlarge designated Free Trade Zone to facilitate the free flow of cargoes. Sixth, the restoration of rail links between North and South Korea is abundantly clear. Thus it needs to enlarge railroad facilities in advance. Seventh, it needs to establish the Port Authority of Busan immediately. Finally, it needs to strengthen port sales and to open events like 'Marine Week 2001' regularly to attract potential canters or big shippers.

Under the influence of birth control and rapid urbanization, China's rural school-age population is on a year-by-year decrease, which has led approximately 300 thousand middle and primary schools to idleness ever since 2000. A majority of these idle schools are located in rural areas, almost one half remaining idle due to vagueness in property right. The disposed schools are less efficient for not being combined with the real situation of rural areas. Based on the opportunity of coordinative development of urban-rural areas, this paper analyzes the situationsin terms of the development of public service facilities and the gap between rural and urban areas over the recent years. Then the effective and sustainable reuse scheme to dispose of the idle schools and reshape them into the facilities for the elders, cultural facilities and medical facilities is proposed from the perspectives of perfecting rural public service facilities and guaranteeing citizens' equal share of public service, which both maintains the public nature of the idle schools, reconciles the fuzzy property right, and boosts efficiency of reuse, saves resources, and reduces investment for perfecting rural public facilities.

Is this a right way in politics that attitude of Japanese scholars to separate Natsume Soseki from the expansionism of pre-war Japan to protect 'sanctity'? Nowadays, most Japanese scholars are regarded to share the desire that minimize the memory of the behavior of Japanese Imperialism in East Asia, such as Korea, China, etc. Furthermore, 'the desire to minimize' inescapably concluded in avoidance, concealment, at last the temptation of deliberate misleading. Until now, the controversy about the Natsume Soseki's travel to Korea and Manchuria has repeated in defence and criticism surrounding the self-awareness and recognition of others of Natsume Soseki, making the expression in a record of Natsume's travel as the subject of study, for example, the degrading expression about Chosun people and scorn for Chinese and Russian. This paper will investigate that Natsume's travel is the political practice which is combined with the desire for the empire, focusing on the political context in the action of journey of Natsume and its contents other than the expression itself.
