Normal development in two six-year-old boys born after prenatal diagnosis of trisomy 20 mosaicism

Prenatal diagnosis of trisomy 20 mosaicism was made in two pregnancies by chromosome analysis of cultured amniotic fluid cells. In both cases, the pregnancy continued to term and a healthy male infant was delivered. Regular assessments up to the age of 6-5 years revealed normal physical and intellectual development in both children.

Environmental principles applicable to supply chains design and operation

In this paper we deal with the problem of identifying environmental principles for the design and operation of supply chains. The operations that are included in supply chains are briefly described along with the approaches that are applied in order to improve their environmental performance. A background of environmental principles for achieving eco-efficiency and building of environmentally friendly organizational systems is presented and emphasis is put on the application of such principles “from cradle to grave”. Then, environmental principles applicable to particular objects of logistics networks planning are identified and commented upon. In addition, selective case studies from the literature, which show the applicability of the formulated principles and their relevance to practice, are discussed. The paper concludes with some remarks regarding the benefits for companies and societies, in general, that occur as a result of the application of the formulated principles.     

Influence of new town development on the urban heat island - The case of the Bundang area

Five new towns have been developed around the Seoul metropolitan area since 1996. However, these new towns generate lots of traffic and related problems in the areas including those new towns and Seoul as a result of increases in population and a lack of ecological-self-sufficiency. Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 198.5 to 1999 rapidly developed which showed a difference of mean temperature above 2.0. Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be 4.5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.     

浅析木制品加工对环境的影响

我国森林覆盖率为16.55％,人均森林面积约为世界平均水平的1/5,为少林国家。而现有木材加工企业利用率不高,加之木制品的大量出口,使森林遭到更大破坏。应采取提高木材综合利用率水平、培育速生丰产林种、以竹代木、调整林产企业产业结构等措施减小对环境的不良影响。

改革开放以来我国粮食生产转型分析及展望

粮食生产转型是乡村生产体系演变的核心内容,以粮食生产转型研究为突破口能够清晰反映区域乡村人地关系的演化过程,为深化城乡融合发展和乡村转型发展研究提供新的视角。本文聚焦我国改革开放以来粮食生产转型历程,并尝试构建我国粮食生产转型的分析框架。研究发现,改革开放以来我国粮食生产转型呈现出“以粮为纲—农业结构调整—综合转型—城乡互动”四个差异化阶段特征。利用GL-RL模型,构建了我国粮食生产转型的分析框架。研究发现,改革开放以来我国粮食生产由Green Loop阶段演化到Red Loop阶段,粮食生产逐渐由本地生产融入到城乡生产网络,驱动粮食生产转型的扰动因素具有多时空尺度特征和跨尺度效应。城乡融合发展、乡村振兴战略、乡村人地关系协调和全球化等因素将会对未来粮食生产转型产生重要影响。此外,优化粮食生产转型与乡村转型发展的关系,将为保障粮食生产有序转型,完善乡村生产体系创造条件。     

抚顺生态城市建设的现状与措施

介绍生态平衡城市的基本条件及抚顺市在建设生态平衡型城市中的基本状况的基础上提出了相关的措施。根据归纳和调查目前抚顺市在经济发展的9项指标中只有2项，环境保护指标15项中只有8项满足生态平衡型城市方面的指标。这说明抚顺市在这方面还存在着很大差距，于是文中进一步提出了相关建议和措施。
