Nowadays

Nowadays, people can get information from various media. Such as radio, newspapers, internet, or television. But there are many people who think television is the worst invention in modern times. Even though many people think television is the worst invention, I believe there are many benefits that we can get from television.
Many people said the news on television is not quality even the accuracy is questionable. In fact, a lot of the latest information on television and its accuracy can be guaranteed. Like news on television related to politics, crime, health, and others.
Opponents also argue that there are people who cannot buy a sophisticated television because of poverty. But research shows that poor people prefer to get information from television. After all, to get the information we don’t need to buy a television that is too expensive. There are many televisions that are affordable.
It should be evident that the arguments against getting news from television are not valid. On the contrary, television is a great invention. Even though poor people cannot buy a sophisticated television, they can still get news from television. And, there is also valid and reliable news. Hence, in my opinion, the arguments mentioned above must be changed.

Nowadays, learning mathematics presents various challenges for many students. Mathematics is often associated as a difficult and tedious subject to learn (Sedig, 2008). Educational games have the potential of addressing those of the challenges. An interactive games can attract student’s attention for hours and hours while providing them with the effective instruction and also an engaging learning experience.
Technology is needed to integrate into math curriculum because technology is necessary for student learning. Accordingly, interactive software and computers are the keys to help students learn mathematics (Twigg, 2011). For example, games have been widely used to enhance student’s mathematics achievement in various domains including problem-solving and algebra skills, strategic and reasoning abilities, arithmetic procedures, and critical geometry skills.
There is a great need for the school teachers to make mathematics become fun and meaningful for their students to motivate them have the intention on want to learn and study mathematics. According to Ahmad et al. (2010), there are many students have problems in learning mathematics for the following reasons: lack of motivation, boredom, little encouragement for self-learning, lack of personal meaning to them, and lack of continuity and focus.
According to Arbaugh et al. (2008), stated that maximizing the use of technology in schools and classrooms could help to improve student learning. Mathematical and collaborative or communicative technologies are two technology types for the teaching and learning of mathematics in today’s classrooms. Collaborative and communicative technologies allow users to create, manipulate, edit, communicate, and share experiences, ideas, and products using words, numbers, symbols, images, audio, and video (Arbaugh et al, 2008).

Nowadays, smartphones significantly impact the life of the people in so many ways. The smartphones technology today are really different in the old days. Before, people are only using radio, landline, and paper writing to communicate in other location or to their family, relatives, friends, and loved ones. And, now the smartphones can help us to connect with our loved ones, friends, and workmates through text, call, and social media they have now taken the world a lot of people could not imagine what life they are now living. Smartphones could either be used as a beneficial factor or it can result in bad habits. Unfortunately, people mishandling the use of smartphones. People are using smartphones most of the time that they are unable to successfully accomplish or finish the required task given to us. In addition, it creates poor communication towards our family, friend, and relatives.
However, then there are also a negatively impact using smartphone technology that can create harmfully habits flow-on affect our health and also the relationship with one another. Besides, people cannot successfully accomplish or finish on what they are doing because of the negative impact of the smartphones and can also affect to damage our eyes for too much use. In addition, people addictive impulse to check their phone every multiple time a day, to check the notification from social media and email that can encourage you to check our phones in every multiple time that we forgot the face-to-face communication.

Nowadays, all sport in entire worlds need a preparation for performances such as jumping, acceleration, speed, agility and others which should involve in both long and short term training program. Long term preparation may include a well-developed fitness training program by coaches while for short term preparation should include warm-up (Khorasani, Mansour, Tabrizi and Yusof, 2010). One part of the warm up preparation includes stretching, which is often performed prior to physical exercises (Khorasani et al, 2010). There are many types of stretching techniques including static stretching, dynamic stretching, combined static and dynamic stretching, ballistic stretching and others (Khorasani et al, 2011).
Generally, stretching is used to enhance the range of motion (ROM) of a joint (Khorasani et al, 2013). Stretching and flexibility training have been very common among the athletic population, making up a large part of training programs as well as pre-event warm up activities for athletes. Flexibility refers to the musculotendinous unit’s ability to elongate with the application of a stretching force, determining the range of motion of a joint. Therefore, the act of stretching can be defined as movement applied by an external or internal force in order to increase muscle flexibility and/or joint range of motion (Oakley, 2017). It has been used by athletics, coach and athletic trainers that increasing flexibility which important aspect of physical fitness, leading to an increase in sport performance and as well as reducing the risk of injury.
Apart from that, agility is consists of several components. They are acceleration, braking, and change of direction. Sporting events involve various modes of movement. In athletic events such as soccer, football, basketball and racquet sports, the athlete sprints, stops and changes direction rapidly. A mere tenth of a second can mean the difference in winning or losing. Troumbley (2010) defined agility as “The ability of the body or body parts to explosively brake, change direction, and accelerate again rapidly under control.” Agility and power activities use stored energy from the stretch-shortening cycle.
Soccer is a sport with a wide range of movement intensities which means that some moments of the game are relatively relaxed and progress slowly, whereas other moments of play demands a maximal bursts of intense exercise. Running, sprinting and cutting is high intensity movements and jogging, walking and standing is a low intensity movements which that occur in varying lengths and intensities in soccer. The skill level, style of play, tactical strategies, playing position and the physical capacity of the individual players on both teams all have some impact on interval work rate of soccer matches (Orenduff, 2010). There are demands imposed on soccer players in terms of fitness readiness requirements to produce power, explosiveness, speed, agility, balance, stability, flexibility and endurance (Dragijsky, 2017).

Nowadays, we are drowning in data which means, that a huge amount of data is daily generated from various sources (Government, health, institutes, industry, media, social networks, mobile networks and so on). Among these various sources, data is generated at an unprecedented rate from offline and online social networks like facebook, linkedIn, twitter, orkut, telephone call networks, disease infection networks, sensor networks and such like. Data is everywhere and we are entering the age of Big data. Big Data is not a framework, not a language, not a technology. Actually, it is a problem statement. Earlier we measured data in Bytes (B), Kilobytes (KB), Megabytes (MB), Gigabytes (GB) and Terabytes (TB) and which are being handled till now. Now, Big Data is the age of dealing with data ranging from Terabytes (TB), Petabytes (PB), Exabytes (EB), Zettabytes (ZB) and Yottabytes (YB). But the traditional data analytics may not be able to handle such large quantities of data. Hence, the term Big Data refers to all the data that is being generated across the globe at an unprecedented rate. This data could be either structured, unstructured or semi structured. Most of the data were born digital as well as exchanged on internet today due to the fast spread of information technology. For example Google processes data of hundreds of Petabytes (PB), Facebook generates log data of over 10PB per month, Baidu a Chinese company processes data of tens of PB, and Taobao, a subsidiary of Alibaba, generates data of tens of Terabytes (TB) for online trading per data 1. To such a large collection of data also called Big data we are facing the most important issue of privacy preserving. Among various sources of Big data, one of the most representative and relevant source is the social media and social network. For example, on average, 72 hours of videos are uploaded to YouTube in every minute 7. Therefore, we are accosted with the main challenge of collecting and integrating massive data from widely distributed data sources and then ensuring the privacy of data.
