The construction of a barrier-free environment contains a rich connotation of human rights protection,and is closely related to the study of human rights protection in China.With the evolution of the concept of barrier-free design and the expansion of its beneficiary groups,constructing a barrier-free environment has become a basic task that benefits all members of society and meets the public needs of all the people,with its core goal expanding from the protection of the rights of the disabled to the protection of the basic rights and interests of all members of society.Building a barrier-free environment from the perspective of the Marxist human rights concept is conducive to safeguarding the people’s right to subsistence and development,and at the same time,it satisfies their demand for the right to pursue a high-quality and better life and reflects the common vision of everyone in society fully enjoying human rights.promoting the construction of a barrier-free environment in terms of legal protection based on China’s institutional advantages can improve and innovate the country’s legislation on the construction of a barrier-free environment,so as to play an exemplary and guiding role in enhancing the international barrier-free level and enable all people to enjoy the good life created through the drive to build a barrier-free environment. 展开更多

Environmental fights are im- portant fights that have been written into fundamental hu- man rights since the 1970s. With economic globalization and sci- entific and technological progress, it is more and more important to educate and protect environmental rights world- wide. As a large developing country, China has significant responsibilities in the field of global environmental safety. However, the awareness and status of environmental rights protection are still not suited to people's demands for environmental rights, making it an important task to carry out scientific planning and environmental rights edu- cation and improve citizens' enjoyment of environmental rights. We propose to start from defining the constitutional status of environmental rights and pro- mote the education and protection of environmental rights at the same time, so as to enhance mutual influence and contribute to creating a good environ- ment for mankind. 展开更多

Smoking is a major health problem in many countries. It has been reported on the effects of education on youth with a reduced smoking rate and developed awareness of avoiding smoking verified as a result of educational intervention. The aim of this study was to verify the relationship between sex, school age, and family smoking and the effectiveness of smoking prevention education program (SPEP) as factors that impact the effectiveness of SPEP in elementary school and junior high school students. The participants in this survey were 6676 students, who attended elementary and junior high schools in Tokushima Prefecture between 2011 and 2015, and attended the SPEP. As factors that influence the effectiveness of the SPEP, we examined school types, sex, smokers in the family. Participants were asked the following questions before and after the SPEP to measure awareness of and attitudes toward smoking: “intention not to smoke cigarettes as adults”, “intention to refuse cigarettes when offered”, “attitude of staying away from smokers”, and “desire that their family will not smoke”. The number of survey collected was 6676, with effective responses from 5974 (90%). Among the 5974, there were 2963 (50%) males and 3011 (50%) females, 5106 elementary school students (86%), and 868 junior high school students (15%). In the case of smoker mother, it was difficult to improve these children’s “intention not to smoke as adults”, “intention to refuse cigarettes when offered”, and smoker father, it was difficult to improve these children’s “attitude of staying away from smokers”, and “desire that their family will not smoke”. Especially, in the case of smoker parents, it was particularly difficult for the SPEP to be effective in improving awareness of and attitudes toward smoking among elementary and junior high school students. 展开更多

Nowadays, African cities are subjected to upsets which result from the extraordinary growth of urban populations. The growth of the population of cities has induced some changes in the structure of the activity of those cities. Agriculture which was formerly confined to the countryside henceforth develops in the urban area and occupies a preponderant place as a strategy of survival, of insertion and of food supplying of the city-dwellers. It has become an activity integrated to the urban tissue through systems of occupying and exploitation of land in the urban area. Population growth (4.81%) between 2002 and 2013 is a critical poverty rate (65%) of the population of Parakou city, entailing a misery perceptible in all its social and economic dimensions. The market-gardening activity has integrated itself to the urban tissue. The objective of this study is to understand how urban agriculture through market-gardening can be a solution for rural farmers who have moved to Parakou city. In this study, documentary research, interviews and field observation are used for data collection. The main results to be signaled among others are: evolution and status of the market-gardening areas in Parakou, the reduction of food insecurity with the permanent availability in quantity and in quality of market-gardening products accessible to the population: the protection of the environment through the drainage of the urban area and the preservation of the diversity of vegetables;the increase of the income of the households of the farmers and the creation of employments. 展开更多

The author, in a series of previous articles, designed the “AB Dome” made of transparent thin film supported by a small additional air overpressure for the purpose of covering a city or other important large installations or sub-regions. In present article the author offers a variation in which a damaged nuclear station can be quickly covered by such a cheap inflatable dome. By containing the radioactive dust from the damaged nuclear station, the danger zone is reduced to about 2 km2 rather than large regions which requires the resettlement of huge masses of people and which stops indus-try in large areas. If there is a big city (as Tokyo) near the nuclear disaster or there is already a dangerous amount of radioactive dust near a city, the city may also be covered by a large inflatable transparent Dome. The building of a gi-gantic inflatable AB Dome over an empty flat surface is not difficult. The cover is spread on a flat surface and a venti-lator (fan system) pumps air under the film cover and lifts the new dome into place but inflation takes many hours. However, to cover a city, garden, forest or other obstacle course in contrast to an empty, mowed field, the thin film cannot be easily deployed over building or trees without risking damage to it by snagging and other complications. This article proposes a new method which solves this problem. The design is a double film blanket filled by light gas such as, methane, hydrogen, or helium - although of these, methane will be the most practical and least likely to leak. Sections of this AB Blanket are lighter than air and will rise in the atmosphere. They can be made on a flat area serving as an as-sembly area and delivered by dirigible or helicopter to station at altitude over the city. Here they connect to the already assembled AB Blanket subassemblies, cover the city in an AB Dome and protect it from bad weather, chemical, bio-logical and radioactive fallout or particulates. After assembly of the dome is completed, the light gas can be replaced by (heavier but cheaper) air. Two projects for Tokyo (Japan) and Moscow (Russia) are used in this paper for sample computation. 展开更多

The Environment Protection Agency Sierra Leone (EPA) is mandated by law to issue Environmental Impact Assessment license. Currently the agency achieves this mandate by issuing environmental licenses manually which always encountered lot of problems of accountability and transparency of the management of environmental licenses and assessment documentation. Client’s information and documentation is usually mixed up while carrying files from one point to the other or from one staff to another. Data on client are stored in a way which makes it difficult for the management to retrieve useful information on time. This paper explores these challenges faced by the manual system of issuing environmental licenses and infer solutions to the current challenges by integrating a Geographic Information Systems (GIS) to develop an Environmental Cadastre administrative System (ECAS) which establishes a web-based information repository database developed with open sources software (Java, PHP, MySQL, QGIS) that published revenues online and made the data available to stakeholders and/or the public to complete the cycle of accountability and transparency. The information is presented and downloadable in a comprehensible and user-friendly manner, which in turn improves monitoring and reporting, and increases effectiveness and accountability of the management of environmental licenses and assessment documentation. The findings show these challenges facing the manual system, the back and forth between EPA and the client in the EIA process, the difficulty in the searching a client record, the mixing up of Client’s information and documentation by carrying files from one point to the other, and the storage of data on client in a way which makes it difficult for the management to retrieve useful information on time, and lack of back up when data or information is lost. Problems encountered in the time-consuming nature of the manual retrieval of files and preparation of prompt and accurate reports make it become a difficult task to accomplish as data and information are difficult to retrieve or collect from various files. Based on these findings, this paper provides the possible solution to the above problems. An online Environmental Cadastre administrative System (ECAS) which establishes a web-based information repository database was designed to capture the full lifecycle of environmental licenses including all stages of monitoring, licenses and payments and seamlessly manage the environmental impact assessment (EIA) licenses. 展开更多
