Qualitative System Dynamics as a Tool in Accessible Design

A description of the Systems Dynamics paradigm is given and the reduced Qualitative System Dynamics (QSD) form explained. A simple example is given to illustrate the diagram construction. The principles of states (levels), rates and feedback loops are outlined. The QSD method is used to address the problem of accessibility by using human control of automation as an example, and applying the QSD method to evaluate the effects of the researcher and user in the de- sign of an accessible artefact. This simple automation model illustrates what can be found out from such a picture, in this indicating how the feedback from users has an influence on the time to deliver such designs.

Towards Smart, Sustainable, Accessible and Inclusive City for Persons with Disability by Taking into Account Checklists Tools

The main characteristics of potential smart cities in the future, smart citizens, smart energy, smart buildings, smart mobility, smart technology, smart healthcare, smart infrastructure, smart governance and education, and finally smart security are the aspects of smart cities. In the smart city, smart accessible infrastructure creates an inclusive environment for people with disabilities, in which they can integrate into the community and enjoy their civil, cultural, political, social and economic rights and entitlements. The aim of this study is to integrate disabled people into society so that they can actively participate in society and lead to a normal life. An integrated approach is needed to ensure that people with disabilities are not left alone. A combination of mainstreaming and targeted action is required for all interventions. People with disabilities have the same basic needs as everyone else: health protection and treatment, basic services, housing and income. Targeted intervention measures need to complement disability mainstreaming by addressing specific needs identified by general responses, including such interventions need not add materially to the overall cost, especially if the requirements of the maximum number of users are considered in the initial planning. This paper recommends how we can use an appropriate design checklist as a guide for our initial architectural concept and smart city planning to facilities reasonably accessible for people with disabilities in private and public buildings, making our cities smarter and more inclusive and helping to improve the quality of life for all people, especially people with disabilities.

Network Garment Style Design System with Remote Information Access and Auto-Connecting Technology

A Network Garment Style Design System (NGSDS) is proposed to enable the remote style structure drawing design of garment. After the development of the system structure based on network that consists of client end and server end at two remote places, a multi-layer part database based on Oracle platform is presented to store information of different parts of garment style. With the acquirement of remote design data at server end using Http technology, the style design is ultimately implemented at the client end using Auto-connecting algorithms. One empirical example is given to show the implementation of the NGSDS.

Managing Accessibility- The Configurational Approach to the Inclusive Design of Urban Spaces

This paper concerns the theme of the universal accessibility to urban spaces, proposing the contribution of configurational approach to their inclusive design. Born in the first Nineties on the roots of the efforts and the studies for reducing material and architectural barriers for disabled people, such discipline extends its sphere and purposes so as to mitigate the effects of spatial exclusion of a wider and wider variety of human categories, up to virtually include any potential urban user. Several questions persuade that a merely functional approach, essentially based on the position of the located activities, cannot be said satisfying： only a configurational approach can account for the effects of the grid configuration on the actual accessibility of its spaces. Our research focuses on Italian urban settlements, which appear as ideal case studies, due to the typical consistency of their urban spaces, which, especially in the inner historical cores, are densely build, geometrically irregular and hence generally far from actually providing a universal material accessibility. Here the impedance of space is much more than a theoretical hypothesis and concrete interventions are generally requested to eliminate or reduce its barriers and to make space actually and safely usable. Rather than at indicating the technical solution of single urban problems, which of course are strongly different each other, the research aims at defining a method suitable for any local context. Such method, integrating into a reliable tool the configurational vision with the functional and interactional approach, will provide a hierarchy of urban spaces with reference to the necessity of their universal accessibility.

Study on Accessible Long-Term Care Mobile Application for Visually Impaired Users

A result revealed by the Department of Statistics, 29,000 elderly people have registered for Visually Impaired Card in 2014, which was 51.2% of all visually impaired people. With annual growth rate of 1.56%, this number increased yearly by 1,100 people. According to WHO, 285 million people worldwide were estimated to be visually impaired, which is 4.24% of overall population in 2012. From age distribution point of view, most visually impaired people, accounted for 2.76% of overall population, were above age 50. In average, there are 7 visually impaired people in every 100 people above 50 years old. In Taiwan, 549,000 people over age 50 are estimated to be visually impaired. Therefore we expect there is a large amount of visually impaired people. The main purpose of this research is to collect adaptability information on the cognitive model of senior visually impaired people on their work status, social participation status, and leisure activities via questionnaire survey. Furthermore, descriptive video service is used to as an accessible long-term care application for visually impaired senior users. To solve disability circumstances and improve home care quality through visually impaired APP POe （proof-of-concept）. The result of this research will serve as an important basis for other researches in related study field, a reference for practice application. As a result in encouraging profit-seeking enterprises design a user oriented products. And even be an opening for mobile accessibility services benchmark on technology social care for disability and senior users.

Secret Sharing Schemes Based on the Dual Code of the Code of a Symmetric （v, k, λ）-Design and Minimal Access Sets

It is known that every linear code can be used to construct the secret sharing schemes. Since the code of a symmetric （V, k, λ）-design is a linear code, this study is about the secret sharing schemes based on C of Fp-code C of asymmetric （v, k, λ）-design.

A Nodal Electricity Market Design Based on Regulated Access to Transmission Network

Accomodation of power system constraints with the market mechanism is encountered as a major challenge along the way toward implementation of different electricity market designs. Allocation of fixe or flow-dependent inter-zone trading capacities by the PX （power exchange） can not be accepted unreservedly. The paper is meant to show that a nodal electricity market design that is based on bids for local energy and a regulated transmission access including allocation of ＂entry-exit＂ transmission capacity would be the desired solution. The market players could easily optimize their portfolio while the TSOs （transmission system operators） are requested to mobilize the network＇s in-built flexibility to increase the cross zonal capacity. In the proposed market design, the PX＇s allocation of trading capacity is clearly separate from the TSO＇s management of the power system operational constraint5. Clear operator roles would enlarge access to electricity market as well as market integration of variable RESs （renewable energy sources） that are critically dependent on short notice access to regionat markets,
