Conventional electronic marquees continue to consume energy even without a human presence. The purpose of this study is to assess energy-savings potential via the installation of the Kinect and IP Power integrated system (KIP) on an electronic marquee; this system will transfer the consumption data for total electricity to electricity-monitoring software (EZ-HD) using a smart meter (EZ-RE) and the ZigBee USB Dongle. An experiment was conducted at one school entrance for two periods during 10 school months, and it was found that the hourly electricity consumption rate for the original electronic marquee system was 1.25 kWh. After the KIP system was installed, the electronic marquee was activated only during human presence, and the hourly electricity consumption rate was 0.97 kWh, providing an average electricity savings rate of 22.4%. The results suggest that the KIP system can help to reduce the consumption of electricity for electronic marquees. Compared to infrared sensor parts used in the past as power switches for electronic equipment, the advantage of the KIP system is that it can distinguish a human presence and would not be interfered by moving objects or animals. In addition, the KIP system has a wider detection range and allows the users to program and detect different electricitysaving contexts and configurations for electronic equipment in different venues according to their individual needs. Therefore, through this test and assessment, we suggest that it is feasible to apply the KIP system in automatic lighting devices, televisions, air conditioners, or security monitoring systems.

This study was conducted as a means to discover common traits associated with small and medium manufacturers, especially ones who have adopted product data management (PDM) systems as a method to control engineering design and manufacturing data. After qualitative interviews were conducted with leading experts across industry sectors, a survey was developed and sent to small and medium manufacturers in the United States. The study concludes a number of interesting findings about the state of PDM usage within various segments of the industry, including general uses for engineering design systems, level of data exchange with customers and suppliers, and satisfaction levels with information querying, concurrent engineering contributions, and imposed restrictions. The study concludes that there are a few major factors that determine a company’s success with using design and data management systems, including frequency of data exchange, data reuse, digital data formats used, and employee counts and locations.

Profitability of a company can be affected by the costs associated with backlogs and large inventories due to the bullwhip effect in the supply chain. This work aims to find an ordering strategy that is practical and can minimize the bullwhip effect. Five strategies with different levels of information about inventory and components along the supply line have been compared with the just in time (JIT) pull strategy and the usage of point of sale (POS) data. This work uses the beer game spreadsheet simulation developed by Adams, Flatto, and Gardner (2008). The simulation shows material and information flow in a four-echelon supply chain. Expressions for cost incurred and profit obtained by each player (manufacturer, distributor, wholesaler, and retailer) have been developed. Graphs for cost and profit with time are plotted. The strategy using POS data is found to be the best, and the pull strategy to be the next best. However, both require discipline. This study shows that putting information about the inventory levels and components of the supply line into an ordering strategy can also minimize the bullwhip effect.

Within technology education, few interdisciplinary models exist that attempt to simultaneously promote the development of environmental literacy and technology assessment skills. EnviroTech, an online professional development project for secondary teachers, was designed to achieve this mission. This report, the second in a series on the project, describes the interdisciplinary content of the EnviroTech project and the impact it had on the students of 18 middle and high school teachers who participated in the project. The curriculum was set against a consumer decision regarding the purchase, use, and disposal of light bulbs. This scenario enabled the examination of environmental processes (e.g., mercury cycle and bioaccumulation), mercury’s impact upon human health, and practices and policies regarding the disposal and recycling of mercury-containing lamps. Teachers employed guided inquiry strategies and several assessment tools (e.g., experimentation and life cycle assessment) to help students hone their technology assessment and decision-making skills. Differences between preassessments and postassessments indicated moderate improvements in students’ knowledge of technology, environmental processes, and strategies to protect themselves against mercury exposure. Significant changes occurred in students’ attitudes with students reporting greater attention to sustainability issues when purchasing and designing products.

Throughout history the success of economies around the world has in large part been influenced by technological growth and innovations. Along with such growth and innovations came higher living standards and an improved quality of life for citizens residing and participating in those economies. However, not all countries were able to grow and develop at the same rate, resulting in considerable differences in economic welfare across populations. As nations around the world address the 21st century, economic growth and prosperity for some nations will depend upon how well their citizens are equipped and motivated to seek new technological discoveries and innovations or participate in the supply chain for the production of such new innovations. Such decision making by individuals will be influenced by both economic and political factors existing within each respective country. After providing a description of economic development, the researchers analyze the current economic conditions in several advanced and developing countries and regions around the world, identifying factors that impact the development in those areas. In the remainder of the article, the focus is placed on the skills needed for 21st century workers and the role technology and engineering education might play in eroding the gaps in skill sets required for developing a workforce, thus moving a country forward in development and affluence.

Alternative teacher licensure, also known as alternative teacher certification, is a growing national trend in education, and it has long been common in the field of career and technical education. Alternatively licensed teachers often enter teaching with a wealth of subject area knowledge due to their previous work experience. Mentorship programs are one of the best ways to help alternatively certified teachers to successfully navigate their first year in the classroom. This study investigated the teacher perceptions of the Indiana Workplace Specialist I (WSI) licensure training program during the 2011-2012 academic year.

In his consideration of thought development, Auguste Comte proposed a three-stage model, in which the mechanism of development may lead to new types of thought. So the process that led to a philosophy of science may be repeated to create a new type of thought. The thought development is attributed to a process of accumulation of challenged but unanswered questions, followed by a decline of interest in that type of thinking. The science stage presented a huge accumulation of achievements, but at the same time it confronts huge challenges. The present work is a theoretical analysis for what is happening because of these challenges. The author believes that the technology may be regarded as a fourth stage for Comte’s model. The technology stage corresponds to globalization as a social stage. Technology has its own methodological way. Owing to the connection between the technology and human need, the development of technology follows a Darwinian evolution model. The process of technology selection that leads to development is the user selection, which corresponds to Charles Darwin’s natural selection.

A proposal is made suggesting the inclusion of historiography (i.e., historical research and the writing of history) into graduate technology teacher education. In particular, a strategy is forwarded to have graduate students in technology teacher education, who are working at schools in different locations, conduct historical research and write histories describing how local inhabitants transmitted technical learning dating back to the earliest human inhabitants. There are potential benefits for the graduate students, the students they teach, and the field of technology teacher education. Collaboration among institutions is recommended. After arguing for the proposal, this article uses a personalized historical narrative approach to evoke a connection with the reader that is not possible with more impersonal approaches and thus illustrating some of the richness of historical techniques.
