Advancement Towards Spatial Justice:The Barrier-Free Environment Construction from a Gender Perspective

Space is both a product and a producer of social relations.In the spatial domain,gender blindness has long existed,limiting women’s rights of access to and use of space,leading to structural oppression of women’s rights,and giving rise to new gender inequalities.The barrier-free environment construction has the functions of eliminating physical barriers and generating societal norms,and when combined with social changes,can facilitate justice correction across multiple dimensions.However,barrier-free environment construction itself,as a means of justice correction,also suffers from gender blindness.There remains room for improvement in the areas of facility construction,information exchange,and social services within the realm of barrier-free environments.In response to this phenomenon,gender equality offers a new critical perspective.Therefore,integrating a gender perspective into the barrier-free environment construction,focusing on the spatial rights of women,especially groups with multiple vulnerabilities,such as disabled women and elderly women,can contribute to the advancement towards spatial justice.

Barrier-free Design of Public Rental Housing

With the aging of society,special groups have had increasing needs of integrating into social life,and higher requirements on life quality,and the society has attached increasing importance to barrier-free design.Taking public rental housing for example,both circulation space and furniture design have to fully consider needs of special groups such as the seniors and the disabled.Barrier-free design in living spaces can help improve their ability of self-care,reduce their dependence on family members,fully demonstrate the"human-centered"design concept of public rental housing,and show the designers’sense of social responsibility.

The Protection of Human Rights in the Construction of Barrier-free Environment--Viewed from the perspective of the Marxist Human Rights Concept

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.

Design of Barrier-free Evacuation for Diverse Crowd on Campus Based on Evacuation Simulation: A Case Study of North China University of Technology

By using evacuation simulation technology and taking North China University of Technology as an example,the barrier-free evacuation design scheme for groups with different needs in campus environment was deeply discussed.Based on the data of building layout,population composition,road system and distribution of shelters in the school,a detailed evacuation model was constructed in the Pathfinder emergency evacuation simulation system.By the simulation during the daytime and at night,the total evacuation time of the whole school,evacuation completion time of each building,selection of evacuation paths and shelter utilization were analyzed in detail.The simulation results show that the distribution of shelters on campus is uneven,and their capacity is limited.As a result,the evacuation paths of the disabled,the elderly and children need to be adjusted frequently,which affects the overall evacuation efficiency.In view of this,the optimization strategies of road renovation and entrances of shelters and buildings were put forward from the perspective of space planning.From the perspective of emergency management,it is suggested to improve the campus evacuation infrastructure and strengthen the evacuation drill for teachers and students.These results provide a solid theoretical support for enhancing the construction of campus barrier-free environment and improving the level of emergency management.

Research on Travel Preferences of Wheelchair Users in Barrier-Free Environments and Improvement Strategies for Adaptive Urban Roads

The construction of a barrier-free environment is an important measure that guarantees the safety,right-of-way,and interests of the disabled,the elderly,and other mobility disadvantaged groups.It is also an indispensable part of the low-carbon urban transportation and a necessary way to protect the rights of mobility disadvantaged groups in green travel.In this paper,the researchers conducted life log surveys on the travels of 10 wheelchair users residing in Beijing with IoT Inspector,a self-developed,wheelchairmountable intelligent sensing device.Wheelchair users’travel preferences and reasons were then analyzed using the image and textual data from the surveys.Combined with a mapping workshop,a comparative analysis was performed on the bumpiness of sidewalk paving materials.The study found that wheelchair travelers’preferred non-motor lanes over sidewalks;substandard curb ramps,unleveled tree pools,limited access widths,and bumpy pavement were the main problems faced by wheelchair users in sidewalk accessibility.In addition,the study explores the inclusive needs and challenges of non-motorized right-of-way for new transportation means at urban planning and traffic management levels.Based on multi-sourced data,this paper discusses the possibility of assessing urban barrier-free environment and representing a narrative of the needs of mobility disadvantaged groups,so as to provide practical experience and technical support to the improvement strategies of adaptive roads.

Modeling study on different discharge characteristics in pulsed discharges with and without barriers on electrodes

High-pressure nanosecond pulsed discharges(NPDs)have attracted increasing attention in recent years due to their wide potential applications.In this study,a barrier-free NPD in pure helium plasma at 120 Torr was numerically investigated by a one-dimensional self-consistent fluid model,and its current–voltage characteristics show very different behaviors from those in pulsed dielectric barrier discharges(DBDs),indicating an entirely distinctive discharge evolution in pulsed discharges with or without barriers on electrodes.Without the control of barriers,the computational data suggest that the discharge current increases very sharply during the plateau phase of the pulsed voltage and reaches its peak value at approximately the instant when the pulsed voltage starts to drop,together with a gradual reduction in the sheath thickness and an increase in electric field in the sheath region,which is in good agreement with experimental observations.By increasing the voltage plateau width and repetition frequency,the discharge current density from the simulation can be substantially enhanced,which cannot be observed in conventional pulsed DBDs,and the spatial distributions of the electric field and charged particles are given to unravel the underlying physics.From the computational data,the distinctive discharge characteristics in barrier-free NPDs are deeply understood,and could be further optimized by tailoring the waveform of the pulsed voltage to obtain desirable plasmas for applications.

The Revelation of Foreign Disabled People Basic Public Service System to China

Disability is an inevitable phenomenon in the development of human society. Creating a good environment for disabled people is not only an important condition of disabled people to fully participate in social life, but also the performance of the social civilization and progress. This article describes some oftbe specific practices of foreign disabled basic public service system including the legislative level, the level of life care and social welfare, etc. Based on the analysis of China system construction of the disabled people public service, proposing build the government＇s macroeconomic, social middle and personal microcosmic basic public service system for disabled people and advocating shared responsibility, which the government should play a leading role, society do good service, the disabled do self-help.

Measuring the Needs for Medical Service in the Retirement Residential Community in Korea

Medical facilities in retirement residential areas provide diverse medical and health-related services to retirees, and they are equipped and programed with various medical services for enhancing retirees’ daily activities. To find out the current status of using medical facilities by retirees, this study surveyed retirees in their fifties, sixties, and seventies, who live in Eunpyeong-gu, Seoul. The survey data was sorted by the types of medical facilities they visit, reasons for their visit, and the types of medical facilities in a retirement residential area they would prefer to visit. The pros and cons of using private and general hospitals can be evaluated further to set up the right strategy to reconcile them;and each type of hospital can be improved by adding those missing elements that the interviewees mentioned. In the broad perspective, this indicates the need to suggest the direction of preparing residential areas that are technically planned for retirees on the basis of the analysis of Korean retirees’ needs.

Palazzo Valentini： Archaeological discoveries and redevelopment projects

Palazzo Valentini, a historical site of Rome＇s Provincial Administration, is located at the heart of the city. The building was purchased in 1827 by Vincenzo Valentini, a banker and consul general of the Prussian Crown. In 1939, with the outbreak of World War II, a fully self-contained, air-raid shelter was built under the courtyard, with an exit tunnel heading onto the Trajan＇s Forum. Archaeological investigations started in 2005 in view of a simple rehabilitation work of the underground level. As work progressed, the sample-plots brought to light new archaeological findings： relics of a huge temple and what remained of two residential houses with thermal baths. We therefore designed an exhibition space with glass surfaces to allow visitors to appreciate the findings while following a path through historical ages： from the 16th-century courtyard to the underground Roman domus （the sumptuous houses of senators and dignitaries of the Roman Empire）, with private baths, to the remains of a Roman temple, and all the way to the Trajan＇s Column pedesta（ by way of the air-raid shelter. Virtual reconstructions, graphic effects, and movies are the means used to revive the hypothetical origina（ appearance of the environments and the daily life of that epoch in order to help us build a prototype of an on-site museum of the third millennium.

Nanoscale color sensors made on semiconducting multi-wall carbon nanotubes

Sub-micron color sensors are developed, using carbon nanotubes （CNTs）. The color sensor consists of an array of two photodiodes with different spectral responses, fabricated using controlled electric peeling-off and doping-free techniques on a single semiconducting double-wall CNT. The CNT photodiodes exhibit intrinsic broad spectral responses from 640 to 2,100 nm, large linear dynamic ranges of over 60 dB, and sub-micron pixel size. This method explores the unique properties of multi-wall CNTs, and may be readily used for large-scale fabrication of high performance color sensor arrays, when arrays of parallel multi-wall CNTs become available.
