我组编《中华邮政国内邮资(1947—1949)》邮集

1947—1949年间，我在大学读书，尝尽了物价飞涨的苦头。因家贫只能靠奖学金维持学习与生活。第一学年我考了全校第一名，获专项奖学金300万元法币，这在当时是个很可观的数目，但时过一个多月才领到钱，已贬值为原来的几十分之一，只够买把计算尺，此事给我留下了不可磨灭的记忆。那时物价的上涨速度，

Extend OWL: toward a clustering integration of collaborative ontologies and agents

In order to solve the problem of how to collaborate with foreign agents and ontologies, a restricted clustering integration approach is proposed. It differs from the traditional approaches in which web ontology language （OWL） is extended by adding some new collaborative interfaces （ i. e., agent-link and ontology-link） to it instead of owl： import. Syntaxes of the interface for foreign ontologies and foreign agents, respectively, and a meta-method of clustering integrated collaboration are discussed. The approach focuses on taking advantage of OWL itself to solve the collaborative problems, and it is feasible to track the contexts of newadded knowledge concerning ontological collaboration.

A scalable topology aggregation algorithm for QoS routing in hierarchical networks

Topology aggregation is necessary for scalable QoS routing mechanisms. Thekey issue is how to gain good performance while summarizing the topological information. In thispaper, we propose a new method to describe the logical link, which is simple and effective innetwork with additive and constrained concave parameters. We extend the method to network associatedwith multi-parameters. Furthermore, we propose a modified star aggregation algorithm. Simulationsare used to evaluate the performance. The results show that our algorithm is relatively good.

Relationship Between Social Economic Agglomeration and Labor Productivity of Core Cities in Northeast China

Dalian, Shenyang, Changchun and Harbin are the four core cities which play an essential role in terms of promoting the economic development in Northeast China. In this paper, the impact of urban agglomeration on labor productivity is explored by making comparisons among these four cities. The model used for analysis is a classical model derived from previous studies. Some indicators, such as population density and economic density, were selected to examine the impact of urban agglomeration on the labor productivity based on the time-series data for the four cities from 1990 to 2007. The four main conclusions are： l） The promotion from the growth rate of population density on the growth rate of labor productivity is limited. 2） The negative relationship exists between the growth rate of employment density and the growth rate of labor productivity. 3） Agglomeration effect exists in the four cities, the highest one is Dalian, Shenyang takes the second place, followed by Changchun and Harbin, and the predominant promotion exerted on the labor productivity is the output density.

EBS-Based Collusion Resistant Group Key Management Using Attribute-Based Enc ryption

The m ajor advantages of EBS-based key rrkanagerrent scheme are its enhanced network survivability, high dynamic performance, and better support for network expansion. But it suffers from the collusion problem, which means it is prone to the cooperative attack of evicted members. A novel EBS-based collusion resistant group management scheme utilizing the construction of Ciphertext-Policy Attribute-Based Encryption （CP-ABE） is proposed. The new scheme satisfies the desired security properties, such as forward secrecy, backward secrecy and collusion secrecy. Compared with existing EBS-based key rmnagement scheme, the new scheme can resolve EBS collusion problem completely. Even all evicted members work together, and share their individual piece of information, they could not access to the new group key. In addition, our scheme is more efficient in terms of conmnication and computation overhead when the group size is large. It can be well controlled even in the case of large-scale application scenarios.

Study on Agglomeration and Fluctuation Situation and Development Countermeasures of Economic Crop Production in Hunan Province

[Objective] This paper aimed to investigate the agglomeration and fluctuation situation of economic crop production in Hunan Province and to propose related development countermeasures. [Method] With agglomeration index and fluctuation index as main indicators, the agglomeration and fluctuation situation of the production of seven major economic crops in Hunan Province in recent decade was studied. [Result] The agglomeration index of sown area and yield of seven major economic crops in Hunan Province showed decreasing orders of ramie 〉 cotton 〉 tobacco 〉 rape〉 citrus 〉 tea 〉 vegetables, ramie 〉 cotton 〉 tobacco 〉 tea 〉 rape 〉 citrus 〉 vegetables, respectively; the fluctuation index of sown area and yield showed decreasing orders of ramie 〉 citrus 〉 vegetables 〉 cotton 〉 tea 〉 rape 〉 tobacco, citrus 〉 ramie 〉 tea 〉 cotton 〉 rape 〉 tobacco 〉 vegetables, respectively. In addition, stable regions, relatively stabte regions and fluctuation regions of sown area and yield in various main producing areas were identified, and corresponding development countermeasures were proposed. [Cenclusion] The key to accelerate the development of major economic crop production in Hunan Province is further improving the agglomeration level of vegetable, citrus, rape and tea production and focusing on maintaining the stability of citrus, ramie and cotton production in main producing areas.

A fast method to evaluate water eutrophication

Water eutrophication has become a worldwide environmental problem in recent years.Once a water body is eutrophicated,it will lose its primary functions and subsequently influence sustainable development of society and economy.Therefore,analysis of eutrophication becomes one of the most essential issues at present.With the ability to deal with vague and uncertain information,and express knowledge in a rule form,the rough set theory(RST) has been widely applied in diverse domains.The advantage of RST is that it can compress the rule and remove needless features by reduction inference rule.By this way,the rule gets effectively simplified and inference efficiency gets improved.However,if data amount is relatively big,it could be a process with large calculated amount to search rules by looking up tables.Petri nets(PNs) possesses so powerful parallel reasoning ability that inference result could be obtained rapidly merely by simple matrix manipulation with no need for searching rules by looking up tables.In this work,an integrated RPN model combining RST with PN was used to analyze relations between degrees of water eutrophication level and influence factors in the Pengxi River of Three Gorges Reservoir.It was shown that the RPN model could analyze water eutrophicaion accurately and quickly,and yield decision rules for the decision-makers at water purification plants of the water quality and assist them in making more cost-effective decisions.

Clusters, Governance and Sustainability

One of the most important aspects of current economical and social reality of each local and regional territory, and very much determinative for its economic development potential, is the nature of its territorial organization of the productive processes, as well as, the characteristics, and sophistication level, of the enterprise strategies that are functioning in it. This paper seeks to contribute to the ongoing discussion on the role of clusters as engines of economic and social development and sustainability of local and regional territories. Based on a study research methodology, we intend to answer to the following research questions： （1） What is the importance of clusters in the increment process of the local and regional conditions of governance and sustainability？ （2） How specific models of clusters＇ governance can contribute to greater territorial setting of enterprises and to increasing the sustainability of its development strategies？ （3） To what extent industrial public policies can increase the sustainability of development solutions for local and regional economies？

Economics and Management of Shipbuilding Clusters： Possibilities for Integrating Croatian Shipbuilding in the EU Shipbuilding Industry

If managed properly, the shipbuilding industry could have a high multiplication effect. This is why it is often considered as the key industry in economic development in many national economies, especially those in transition. The three major players in the global shipbuilding industry are South Korea, China and Japan. Europe is positioned forth, but its market share is decreasing rapidly. This is also the case with the Croatian shipbuilding industry. This paper aims to critique the level of adaptability of Croatian shipyards to the rapidly changing environment of global industry. It also relates the question of survival and sustainable development of Croatian shipbuilding and strategic positioning of European shipbuilders. The results of this research had shown that without clusterizing the shipbuilding industry at EU integration level, and not at national levels, Europe will soon loose the struggle for market position improvement or even maintenance to the far more organized Asian rivals. Findings regarding the Croatian shipbuilding industry indicate the absence of a viable strategy on the national level. Furthermore, the paper tries to prove that success will be based on the possibility and will of Croatian shipbuilders to form strong collaborations mad business networks with subcontractors and other institutions. This should not be limited only at national level, but should incorporate different kinds of EU shipbuilding consortiums and clusters as well as other forms of strategic alliances.

An Evaluation of South Korean Container Sea Port Development Policy

As Busan New Port has been developed with a total scale of 30 berths in 2020, the chronic problem of Busan port, a lack of port facilities, is being addressed, and there is a growing interest in regard to port development with an optimal scale. The Korean container port development under the master plan for national port development reveals a severe problem of excess supply of port facility in some ports. This paper, the authors analysed the second and the third master plan for national port development implemented in 2001 and 2011, and a revised plan in 2006, along with the amended predictions for container throughput. Furthermore, the effectiveness of the implementation of the initial plan, and the current situation of South Korea＇s main container ports of Busan, Gwangyang, Incheon, and Pyeongtaek ＆ Dangjin was examined. Through the analysis of port vitalizations, we have examined the actual problems for the prediction of container throughput. Also, this research analysed the functional difference of each port and organized the function of each one discriminatively. Therefore, identifies the problems, which arise with making the container throughput forecasts, which is a fimdamental aspect of existing port development policy, and suggest a direction for future port development by synthesizing the results of analysis.
