Paper Title :: Home Automation System for Electrical Appliances Using Android Application

Page Number :: 01-12
Every home appliances comes with a default way of switching in a traditional way to turn on and turn off by touching the switch. Sometimes, it is not comfortable for the elderly, or even the young and busy individuals especially when the frequent switching operation is required. Thus, an easier method of switching is needed to replace the manual switching method using an advanced switching method for electronic home appliance through the use of android application via our mobile devices. The research aimed to design and construct a prototype of a home automation system for electronic appliances, which gives the user complete control over all electrical appliances of the home using Wi-Fi (Wireless Fidelity). The system is a Wi-Fi based home automation system which has two main parts hardware and software. The system is developed using NodeMCU modules which receives, sends data and communicates with other components via Wi-Fi. The software development methodology used in the work can be described as a mix of incremental development model and the evolutionary prototyping approach. The Incremental model helps to divide the segment into small parts (e.g., functionality and features) each having objectives and constraint that was determined before the development. By using the evolutionary prototyping approach helps to improve the system by adding new features and functionalities. The programming language used for the system development is C++ to enable the NOdeMCU. The system is capable of switching on/off electrical appliances such as light bulb, fan, socket, AC-Air Conditioner automatically and can as well determine the time for power usage in the home through the mobile application thereby reducing cost and better safety for the equipment.

Paper Title :: Case Study about Three Consumer´S Cooperatives of Organic Products in the South of Brazil was a Part of Short Food Chains
Author Name :: KLEIN, Adriano Diego || KLEIN, Caroline Rippe de Mello || SCHULTZ, Glauco
Country :: Brazil
Page Number :: 13-18
The theme of this article is to explore the case of three consumer cooperatives in the south of Brazil and observe the daily business, organization and supply chain, using as reference the “short food supply chain” to think and understand in which way the theory and praxis are close or far between themselves. The data was collected with research in the stores and interviews with the key-people in them, most of them the owners and some trustfull employees. Analyzing reasons for the beginning of the business, like a mobilization and participation of members and partnering with technical support centers, NGOs, universities and farmers groups who formed the short chain and awareness. The research found some curious results, like thediversityof inside organization between the cooperatives with different kind of food chain commerce at the same time, that became clear on these institutions which are much more entanged with the ideas of short supply chains, local consumption and sustainability in theory, and all of them tried to put it on in practice this.
