This study evaluated the trend of diarrheal diseases managed with zinc supplementation by comparing it with diarrheal diseases managed without zinc supplementation at the University of Port Harcourt Teaching hospital (UPTH), Nigeria. The study was a descriptive retrospective study done at the Diarrhea Training Unit (DTU) of UPTH to determine the effect of zinc supplementation in the management of diarrhea in children under 5 years. Out of the 134 case records studied, of children aged 0 to 59 months who presented with diarrhea at the DTU, 57 children did not receive zinc supplementation between October and December, 2007 and 77 children received zinc supplementation between October and December 2009. The results showed that (74) 96.1% of patients who received zinc supplementation, and (48) 84.2% of those who did not, had no repeat diarrheal episodes when seen at the follow up clinic. On the other hand, 1.3% of those who received zinc supplementation and 1.8% of those who did not, had increased episodes of diarrhea when seen at the follow up clinic. Of those who received, and those who did not receive zinc supplementation, 2.6% and 14% respectively, had reduced episodes of diarrhea. These findings clearly demonstrate the effectiveness of zinc supplementation in halting the course of diarrheal diseases in children aged 0 to 59 months. We therefore advocate for the use of zinc supplementation in the management of diarrhea in

Study on Spatial Planning and Rational Pattern of China's Urbanization Development:Review on Research Report

China City Planning Review 2014年第2期23卷 27-37页

作者： Xiaojiang LI Li ZHU Yongbo ZHANG China Academy of Urban Planning and Design China Academy of Urban Planning and Design Shenzhen Department of Urban Construction Engineering China Academy of Urban Planning and Design

Based on an in-depth survey of different typical areas that are selected in different regions and at different levels, this paper identifies the general characteristics of China's urbanization, the impacts that economic development driven by both exogenous and endogenous engines has on the spatial pattern of urbanization, and the two urbanization paths:gradient development and hierarchal advancement. By analyzing such factors as population growth, population mobility, and economic and industrial development, it sums up five spatial patterns for future urbanization development trends. Through the analyses on the three aspects:whereabouts of the present 260 million migrant workers and their families, whereabouts of the new-born population and new working-age rural population, and the migrant scale of the existing agricultural labors moving to non-agricultural industries, this paper predicts that China's urbanization rate will slow down in the next five to ten years, and will reach about 65 percent in around 2030. On the basis of the analyses, it puts forward that "Five-Six-Eleven" regional pattern of urbanization should be established to guide the overall strategy for spatial pattern optimization. To optimize the spatial pattern of urbanization, it proposes specific strategies including coordinated development of large, medium-sized, and small cities, and small towns, as well as urbanization development strategies of differentiation according to different classes and regions.

中东作为当前全球矛盾和冲突最为复杂和集中的地区，短期内将难以化解各种矛盾和建立全面的安全体系。但中东的波斯湾地区作为世界主要能源产地，其安全局势直接关系到全球经济和政治的稳定，因而有必要首先在这一次区域地区建立安全秩序。伊拉克战争后，波斯湾地区安全局势出现了重大变化。长期和周边邻国关系紧张的伊朗，现已崛起成为波斯湾地区实力最强的国家。为了抵制西方国家干预和维护海湾地区稳定，伊朗明确提出了和波斯湾其他国家共同建立地区安全秩序的设想。为此，伊朗近年来和伊拉克以及海湾合作委员会成员国积极开展对话改善关系，并向邻国保证其核计划仅限于调整能源结构的和平用途。伊朗为此所做的努力，现已为建立波斯湾次区域安全秩序创造了一定条件。
