During this century, technology has its top place since people always try to seek for better technology support for their lives. Technology has been used to make the life of people become simpler and easier. Time, money and efforts have been devoted to invent new and higher level of technology. This technology enables people to do lots of outstanding achievement such as flying to the moon and discovering new star on the sky. However, there are two different opinions about technology. One side says that technology is the best tool to create simpler and easier lives while another side says that technology is harmful for the environment. In fact, those two different opinions are just to be true. Technology can be helpful but harmful at the other side.As an answer of these two different opinions, there is a huge need of green technology or environmental technology. Green technology here means technology which is able to conserve natural environment and resources. Green technology makes people’s lives simpler and easier without providing harmful effect to the people and their surrounding environment. Green technology helps to reduce the effect of prior technology that has made the environment damaged or destructed. This technology repairs the damaged part of nature. Green technology also helps people to maintain and preserve the environment such as purifying water needed in rural areas. Moreover, green technology is also meaningful to absorb the chemical toxic in the air which results in better air for people.Knowing the facts that green technology is very helpful for people’s life, individuals and companies have sought many ways to use this technology wisely. The problem about energy which is limited has always become the problem of every person in every year. Therefore, people now think that green technology [http://www.letmegreen.com/category/green-office] will help people reducing the consumption of energy itself so that they can be economical on energy consumption. Most companies seek for this kind of technology in order to minimize the budget spent for technology and also to provide better working environment for the workers. This will help the company a lot to be sustainable in this global financial crisis. That is why the companies and individuals try to find best application that can reduce the energy consumption. The use of green technology is believed as the best and only way to overcome energy crisis lately. It is also provides simpler application. Now, it is your own choice whether you want to take the complex and difficult technology or green technology which is proven to be less energy consumption.

Communication is critical to continued human development throughout our life span. It is what allows us to share thoughts, feelings, wonderings, and knowledge with others. Whether you are a verbal or nonverbal communicator, the vast majority of communication we do is through nonverbal channels.So if nonverbal communication makes up a substantial portion of our communicative experience, what does it involve? Many of us associate facial expression and gestures with nonverbal communication, but these are not the only two types involved. There are, in fact, eight different types of nonverbal communication:

Facial Expression This makes up the largest proportion of nonverbal communication. Large amounts of information can be conveyed through a smile or frown. The facial expressions for happiness, sadness, anger, and fear are similar across cultures throughout the world.
Gestures Common gestures include pointing, waving, and using fingers to indicate number amounts.
Paralinguistics This includes factors such as tone of voice, loudness, inflection, and pitch. Tone of voice can be powerful. The same sentence said in different tones can convey different messages. A strong tone of voice may indicate approval or enthusiasm, whereas the same sentence said with a hesitant tone of voice may convey disapproval or lack of interest.
Body Language and Posture A person’s posture and movement can also convey a great deal of information. Arm crossing or leg-crossing conveys different meanings depending on the context and the person interpreting them. Body language is very subtle, and may not be very definitive.
Proxemics This refers to personal space. The amount of space a person requires depends on each individual’s preference, but also depends on the situation and other people involved in the situation.
Eye Gaze Looking, staring, and blinking are all considered types of eye gaze. Looking at another person can indicate a range of emotions including hostility, interest, or attraction.
Haptics This refers to communicating through touch. Haptics is especially important in infancy and early childhood.
Appearance Our choice of color, clothing, hairstyles, and other factors affecting our appearance are considered a means of nonverbal communication.
By the time most children are one year old, they are experts in nonverbal communication. They have spent the whole first year of their lives making their wants and needs known, as well as sharing their experiences through nonverbal channels. Around the time of their first birthday, they add the next layer to their dynamic communication repertoire with the verbal piece. Even with the addition of verbal communication, nonverbal expression continues to be the main mode of communication for children as they add more and more words to their vocabulary. Even after children are talking in sentences, nonverbal communication continues to add meaning and structure to the messages being sent and received.This use and understanding of nonverbal communication becomes automatic for ‘neuro-typical’ children. It is so automatic that many of us are completely unaware that we employ facial expressions and gestures, or that we are using this information to enhance the words we are hearing from our communication partner. We continue to use this mode of communication throughout life.Think about the word “no,” which can be interpreted in many different ways depending on the nonverbal communication that is being conveyed along with the word. If we say “noooo” with a wrinkled nose and a questioning tone or funny voice, this could convey that we are unsure or don’t really believe what we are hearing. If we hear someone say “NO!” with a loud, or harsh voice, we can interpret that they person is angry or wants an action to be terminated. If someone asks you if you would like a drink, you may answer with “no”; but your tone of voice will most likely be even with little inflection, and your face may just be neutral. In each of these examples the person was saying “no,” but there were three different meanings being conveyed. Without nonverbal communication, it would be difficult to know how to interpret the word.Many children with autism spectrum disorders have difficulty interpreting multiple modes of communication, and because of this they often miss the nonverbal communication piece that allows accurate interpretation of what is said. In the examples provided above, most children with autism spectrum disorders would only hear the word “no” but miss the nonverbal pieces which help to interpret which “no” is being communicated. This misinterpretation can lead to frustration on the part of both the communicator and the child who is struggling to understand what is happening. At other times, the child may interpret a facial expression, tone of voice, or gesture but not hear the words that went with the nonverbal, which again results in miscommunication. These breakdowns make it difficult for the child to make sense of his/her world.Working to improve the use and understanding of nonverbal communication is essential for a person with an autism spectrum or neurological disorder. In most cases, working to improve nonverbal communication is the best place to begin improving communication abilities. Expanding the ability to use and understand nonverbal communication provides the necessary foundation for building meaningful dynamic communication. Just as a neuro-typical infant begins by communicating nonverbally, going back and teaching this mode of communication for children who may have missed this step is the foundation for productive communication throughout life.Teaching nonverbal communication should be done in a natural way that makes sense for each individual child. Telling a child, “look at my face,” or showing a child several pictures of people’s faces and having him/her identify the emotions he sees is not a natural way to work on nonverbal communication. Spending time doing activities with the child where the adult uses very little verbal communication, but is communicating through nonverbal channels, is an effective way to begin introducing nonverbal communication. Playing games where you have changed the rules slightly so as to use only nonverbal communication can also be a fun and more natural way of working on nonverbal communication. For example, you might play Simon Says, using a made up signal for when Simon says to do something. Playing charades can also be a fun way to work on nonverbal communication in a natural context. Take a walk with your child; but instead of saying, “hey look at that dog,” you might pause, point and vocalize, “oh” with a rising inflection to draw attention. There are many ways to work on nonverbal communication that can be explored and used to build this critical foundational piece of communication.
