Smart classroom: Gateway for ubiquitous classroom
In educational environment, the use of new pedagogies such as collaborative learning requires an evolution from a traditional classroom model to active classroom. The students should be able to share resources to collaborate with each other through computers, tablets, or other devices. The design of smart classroom should enable the control of audiovisual equipments, projectors, interactive whiteboards, in order to facilitate interaction among teachers and students. Ubiquitous computing or pervasive computing is a concept where processors and sensors are embedded in various physical objects to form a network and communicate information. Applying the pervasive computing can facilitate the collaborative learning by creating a smart learning environment. The ubiquitous classroom should be able to support interaction of heterogeneous devices connected through wireless links to a gateway. This paper presents a model of classroom that makes several smart devices such as laptops, tablets, projectors connected through a gateway in order to encourage communication of information between learners and the smart environment. Also, the gateway manages classroom smart devices by automatic detection and connectivity and it serves as application execution platform. Finally the gateway allows the classroom to be remote managed as well as the remote integration of application.

Civilization has historically flourished around rivers and major waterways. Mesopotamia, the so-called cradle of civilization, was situated between the major rivers Tigris and Euphrates; the ancient society of the Egyptians depended entirely upon the Nile. Rome was also founded on the banks of the Italian river Tiber. Large metropolises like Rotterdam, London, Montreal, Paris, New York City, Buenos Aires, Shanghai, Tokyo, Chicago, and Hong Kong owe their success in part to their easy accessibility via water and the resultant expansion of trade. Islands with safe water ports, like Singapore, have flourished for the same reason. In places such as North Africa and the Middle East, where water is more scarce, access to clean drinking water was and is a major factor in human development.*
With this perspective, and our own “home waters” situated in the Great Lakes, we are attentive to water management standardization activity administered by International Organization Standardization Technical Committee 224 (ISO TC/224). The scope of the committee is multidimensional; as described in the business plan linked below:
Water-related management standards define a very active space; arguably, as fast-moving a space as electrotechnology. The ISO TC/224 is a fairly well accomplished committee with at least 16 consensus products emerging from a 34 nations led by Association Française de Normalisation (@AFNOR) as the global Secretariat and 34 participating nations. The American Water Works Association is ANSI’s US Technical Advisory Group administrator to the ISO.
We do not advocate the user interest in this standard at the moment but encourage educational institutions with resident expertise — either on the business side or academic side of US educational institutions — to participate in it. You are encouraged to communicate directly with Paul Olson at AWWA, 6666 W. Quincy Avenue, Denver, CO 80235, Phone: (303) 347-6178, Email: polson@awwa.org.
The work products of TC 224 (and ISO 147 and ISO TC 282) are also on the standing agendas of our Water, Global and Bucolia colloquia. See our CALENDAR for the next online meeting, open to everyone.

We track action in the catalog of this consortia standards developer because we continually seek ways to avoid spending a dollar to save a dime; characteristic of an industry that is a culture more than it is a business.
While not an ANSI accredited the FASB/GASB standards setting enterprise’s due process requirements (balance, open-ness, appeal, etc.)* are “ANSI-like” and widely referenced in education enterprise management best practice. Recent action in its best practice bibliography is listed below
ACCOUNTING STANDARDS UPDATES ISSUED
For obvious reasons, we have an interest in its titles relevant to Not-For-Profit Entities
WHAT IS THE FASB NOT-FOR-PROFIT ENTITY TEAM
At present the non-profit titles are stable with the 2020 revision. That does not mean there is not work than can be done. Faculty and students may be interested in the FASG program linked below:
Also, the “Accounting for Environmental Credit Programs”, last updated in January, may interest colleges and universities with energy and sustainability curricula. You may track progress at the link below:
EXPOSURE DOCUMENTS OPEN FOR COMMENT
We encourage our colleagues to communicate directly with the FASB on any issue (Click here). Other titles in the FASB/GASB best practice bibliography are a standing item on our Finance colloquia; open to everyone. Use the login credentials at the upper right of our home page.

Electromagnetic Interference in Hospital Environment:
Case Study of the Intensive Care Units of a University Hospital
Victoria Souza Fernandes

Federal University of Campina Grande, Campina Grande, Brazil
Abstract: Electromagnetic (EM) sources are abundant in the routine of a hospital. Such sources can be for personal use, be part of the set of electromedical equipment or the building structure. This article presents the verification of electromagnetic interference between field sources and hospital devices, since electromagnetic interference is a factor that puts the correct functioning of these equipments at risk. As a consequence, patient’s lives are also put at risk. Since in many cases, the vitality of the patient depends exclusively on medical devices, electromagnetic fields were measured inside and outside the intensive care units (ICUs) of the University Hospital Alcides Carneiro (UHAC) with all hospital devices working normally. The electromagnetic field values obtained at the hospital were compared with the values imposed by the International Electrotechnical Commission (IEC).
During today’s colloquium we audit the literature that sets the standard of care for mechanical engineering design, construction operations and maintenance of campus district energy systems — typically miles (kilometers) of large underground pipes and wires that characterize a district energy system. Topically, Mechanical 400 deals with energy systems “outside” or “between” buildings; whereas Mechanical 200 deals with energy systems within an individual building envelope.
A campus district energy system is a centralized heating and cooling network that supplies thermal energy to multiple buildings within a defined area, such as a college or university campus. The system generates steam, hot water, or chilled water at a central plant, which is then distributed through an underground network of pipes to individual buildings for space heating, domestic hot water, and air conditioning. By consolidating energy production and distribution, campus district energy systems can achieve significant energy and cost savings compared to individual building systems, as well as reduce greenhouse gas emissions and improve reliability and resiliency of the energy supply.

It is a large domain and virtually none of the organizations listed above deal with district energy systems outside their own (market-making) circle of influence. As best we can we try to pull together the peak priorities for the real asset managers and engineers who are responsible for these system.
* Building services engineers are responsible for the design, installation, operation and monitoring of the technical services in buildings (including mechanical, electrical and public health systems, also known as MEP or HVAC), in order to ensure the safe, comfortable and environmentally friendly operation. Building services engineers work closely with other construction professionals such as architects, structural engineers and quantity surveyors. Building services engineers influence the architectural design of building, in particular facades, in relation to energy efficiency and indoor environment, and can integrate local energy production (e.g. façade-integrated photovoltaics) or community-scale energy facilities (e.g. district heating). Building services engineers therefore play an important role in the design and operation of energy-efficient buildings (including green buildings, passive houses and zero energybuildings. uses. With buildings accounting for about a third of all carbon emissions] and over a half of the global electricity demand, building services engineers play an important role in the move to a low-carbon society, hence mitigate global warming.
