Using plants for health: Indigenous knowledge in health care in a tribal region of Bihar,India

While the potential of indigenous knowledge for health care is fully recognised in the literature and by many health professionals, the practices of so many indigenous peoples go unrecorded and untested. Indigenous knowledge remains essentially untapped, an unwritten resource involving information, language and skills in many groups, languages, cultures and environments. An attempt is made in this paper to identify selected indigenous health technologies in a tribal area of Bihar State, India; to describe the treatments, their application and preparation; and to link the traditional practice with the relevant scientific information to test or determine the validity of the practices. These practices were found to be effective in the treatment of a variety of health problems, and most were also scientifically confirmed. The paper argues, however, that other plant uses practised by tribal people still need to be explored: in order to popularise more widely the authenticated practices; to preserve indigenous knowledge; to integrate or blend it with scientific knowledge so that health professionals and healthcare users may benefit from a wider range of healthcare strategies which are environmentally unthreatening.     

内蒙古煤矿环境地质问题及其防治对策研究

煤炭是内蒙古最具优势的矿产资源 ,其产值几乎占到该区工业产值的一半。由于历史及政策等因素的影响 ,煤矿开发破坏矿区环境资源、诱发地质灾害和导致环境污染。不同地域矿山开发诱发的环境地质问题不同 ,露天和地下不同的开采方式诱发不同的环境地质问题。国有大中型老矿区地面塌陷问题较为严重 ,成为制约矿山持续发展的主要因素之一。乡镇及个体小煤矿“只开发 ,不治理”加剧了矿山地质环境的恶化。在西部大开发中 ,要吸取“先开发 ,后治理”的历史教训 ,走资源合理开发利用与矿区生态环境保护的绿色矿业之路     

Physical Effects of New Devices for Bricklayers

Bricklaying is a physically demanding job. Bricklayers frequently flex their trunk to pick up bricks and mortar and position these in a wall. The experienced workload is highest working with bricks at 0 to 50 cm from the floor. In this study the effects of 2 devices that have proven to be feasible in practice are evaluated.

The 50 cm raise due to the 2 devices is experienced as comfortable, the estimated lumbar compression force was reduced, and observations indicate likewise. It is discussed that the field experiments have many drawbacks. Nevertheless, based on this study in combination with other literature the improvements could be recommended.     

佳木斯市农村环境问题研究

畜禽养殖业污染、生活垃圾随意堆放、农用化学物质、农用塑料制品污染、工业经济发展和城市化扩张对农村环境产生破坏是佳木斯市环境污染的主要表现。资金匮乏、法律制度不健全、农民环保意识不强、农业技术发展与环境保护不同步、各部门沟通较少是造成农村环境污染的主要原因。通过加强法制建设、改变农业生产模式、走生态农业发展之路、加大资金投入和宣传教育力度、部门间协调,可有效解决农村环境污染问题。     

中国环境影响评价管理的现状、问题及展望

文章在客观分析中国环境影响评价的发展历史、现有法规体系、管理体制和主要成绩的基础上,指出了环境影响评价管理中存在的规划环评滞后、监管环节薄弱、公众参与不足以及队伍能力欠缺等主要问题。结合中国环境影响评价管理的特点和相关领域的发展变化,对未来环境影响评价工作的开展进行了展望。认为应该重点加强四个方面的工作,即通过确立环境目标来促进经济增长方式的转变,通过完善空间规划体系为规划环评提供基本依据,通过加强环境监管来促进环保措施落实,通过加强队伍能力建设来提高环评质量。     

Education for sustainable development – an inter‐disciplinary pilot module for undergraduate engineers and scientists

The coming together of a number of initiatives provided a springboard for an innovative pilot programme in education for sustainable development. For some time problem‐based learning has gathered momentum as an approach to educating professionals. More recently, there has been a burgeoning interest in inter‐disciplinary approaches to the complex societal and environmental issues that face the world as a whole. At the same time, professional engineering institutions have been reflecting on appropriate approaches to the education and development of future engineers. Building on work already undertaken by some of the authors, the Royal Academy of Engineering sponsored an inter‐disciplinary pilot programme in sustainable development for undergraduate engineers and scientists in the University of Manchester. The pilot was innovative not only in its inter‐disciplinary approach to sustainable development but also in its approach to the development of the curriculum. Inter‐disciplinary exercises were designed that enabled a contextual, active, collaborative and cumulative approach to learning. The assessment was also designed to align to the learning approach. Evaluation of the pilot programme suggests that it was well received by the students, and the post‐doctoral researchers who acted as facilitators, and also that there were gains in both understanding of the issues and also in approaches to learning.     

Location set covering for waste resource recycling centers in Taiwan

The efficiency of Taiwan's waste management and resource recycling systems has been well recognized in recent years, but the present model used to locate recycling centers and to assign collection depots to those centers continues to show low efficiency. To address this issue, the study herein suggests implementing a new location-planning and assignment model to reduce the number of existing recycling centers. Such a reduction would reduce the use of land resources. Moreover, the total transportation distance would decrease through the efficient assignment of collection depots to recycling centers. On the basis of results from previous studies, this study proposes a 2-stage location set covering problem-P-median integrated model that obtains exact solutions using heuristic algorithms on the basis of set operations. The results of numerical analyses show that the model introduced in this study is effective in solving the problems stated above as well as in improving the layout of Taiwan's existing recycling centers.     

中国流域水资源生态补偿的法律问题与对策

随着我国经济社会的不断发展,水资源不足和水质污染引起的水危机已经成为许多地区可持续发展中的重要制约因素。在这种背景下,为了平衡环境、社会和经济多元利益,寻求先进的法律机制来调节平衡、保护流域生态环境、促进流域的可持续发展已成为一种共识。开展流域水资源生态补偿是实现流域上下游之间等相关方利益公平的关键所在。但由于我国缺乏生态补偿立法和相应的制度安排,流域水资源生态补偿目前仍面临许多问题：我国流域水资源生态补偿进展缓慢、法律制度滞后、部分法律法规彼此之间矛盾和相互冲突、流域水资源生态补偿的法律制度缺位、立法模式不适合当今流域生态环境问题解决等。本文通过对我国有关涉水法律中存在问题的分析,提出一些有关流域水资源生态补偿法律制度建设和完善的对策,以期对中国流域水资源生态补偿的推进和进一步实现水资源的可持续利用有所帮助。
