<正>男女平等基本国策是中国对国际社会性别平等主流化的承诺。社会性别主流化,也称把社会性别意识纳入社会发展和决策的主流的提法,最早反映在1985年第三次世界妇女大会通过的《到2000年为提高妇女地位前瞻性战略》(简称《内罗毕战略》)中。1995年第四次世界妇女大会通过的《行动纲领》确定将性别观点纳入社会发展各领域

Applied undergraduate education should focus on the cultivation of students' practical ability.AutoCAD is not only a fundamental but also practical course for civil engineering.So,we should combine with the features of AutoCAD application in civil engineering,design AutoCAD course from the teaching content,teaching mode,and teaching method,to adapt to Undergraduate AutoCAD teaching of applied civil engineering.

Both women's movements and governments have attached a great importance to studies of gender mainstreaming ever since it was endorsed as a global strategy to promote gender equality in 1995. This paper reviews recent studies on gender mainstreaming by gender and development academia. I argue that different approaches yield contrasting views on the progress of gender mainstreaming. While a position on changes in public administration and policy suggests a historical improvement in gender equality worldwide, a perspective of social transformation discerns limited impact of gender mainstreaming, if at all, in bringing about fundamental changes in gender relations. To further gender mainstreaming in face of challenges and opportunities, there is a need to integrate different conceptual frameworks and approaches, explore comprehensive methods of organizational capacity building and strengthen the role of women's movements and organizations in promoting gender equality.

Energy-saving development of Zhengzhou is investigated through questionnaires and scene researching on existing residential buildings,involving in construction year and layers,building orientation,building structure,heating and cooling mode,available and afford able energy-saving methods and building envelope.It proposed energy-efficient retrofitting measures of external wall,window,roof and heat ing systems for existing residential buildings in Zhengzhou,considering local geographical position and climate characteristics.

With energy and environmental issues are increasingly becoming the focus of global attention, building energy efficiency is one of the basic strategic planning for sustainable development in China, it is developing rapidly, and gets impressive results. Nevertheless, the building energy saving in our country that what has a lot of questions. For this reason, virtual simulation technology is made full use in building energy-saving and made practical engineering application analysis, a new method will be sock in building energy-saving design.

With the continuous development of the architectural design concept,people-oriented design not only has played a guiding role,to the public residential building design also plays an important role in mining ground buildings.Taking Xinglongzhuang Coal Mine ground building design as the background,the design conditions are analyzed.Five points of mining ground architectural design conception are put forward.It’s hoped that it’s helpful for the future in the mine construction and design.

Applied undergraduate should focus on the cultivation of students' practical ability.This paper analyzed the necessity of 3D architectural performance study for the students of architecture majors,suggests that the course should be combined with the students' employment,and encourages students to participate in the relevant student competitions,develop thinking,and improve the students' practical innovation ability.

This essay is based on the angle of view which social sex will be involved in the social management and the mainstream of policy.And at the line of Strategy——mainstreaming and specialization complementing each other of thought and based on the investigation of Hunan,Hebei,Anhui and Sichuan to discuss the establishment of caring left women's path and mode under the social management mode. It is investigated that effective social management mode of caring left women has several followed feature:on the one hand,the relevant government departments with the mainstreaming method,will take left behind women issues into their daily work,and to raise it to social management and policy agenda.On the other hand,women federations and left behind women spontaneously organized by specialized method,to provide social support and service according to the special difficulties of women left behind.These methods which combine the mainstreaming and specialization are called Twin-Track Strategy.This method can not only solve the left women's difficulties,but also build up an effective social management and service net which service the specific crowed catching in trouble under the social development.

Residential thermal environment and design are not the same in different thermal division.For cold areas,energy-saving residential buildings from the construction site selection,planning,architectural design and equipment selection,we should pay attention to the use of energy-saving technology,not only should satisfy requirements winter heat preservation,even give attention to summer heat insulation.

<正>我国是一个能耗大国,而建筑用能在不断增长,造成对我国能源供应系统的巨大压力,因此生态可持续性建筑是未来发展的必然趋势。国家在建筑节能优先领域规定,首先从居住建筑开始,逐步到公共建筑,然后是工业建筑;地域上首先从北方采暖地区开始,然后发展到夏热冬冷过渡地区,并扩展到南方炎热地区。建筑能耗主要包括建造、使用过程中的能耗,占了我国总能耗的30%,剩下的是建材耗能,这一部分占我国总能耗的16.7%。由此可见,降低建造和使用能耗是降低建筑能耗的首要
