TV
Is it important to know what your kids are watching? Of course yes. Television can expose things you have tried to protect them from, especially violence, pornography, consumerism, etc.
A study demonstrated that spending too much time on watching TV during the day or bedtime often causes bedtime disruption, stress, and short of sleep duration.
Another research found that there is a significant relationship between the amount of time spent for watching television during adolescence and early adulthood, and the possibility of being aggressive.
Meanwhile, many studies have identified a relationship between kids who watch TV a lot and being inactive and overweight.
Considering some facts mentioned above, protect your children with the following tips:
1. Limit television viewing to 1 – 2 hours each day
2. Do not allow your children to have a TV set in their bedrooms
3. Review the rating of TV shows that your children watch
4. Watch television with your children and discuss what is happening the show
Ssya punya tugas mapel fisika :
Mesin carnot dengan efisiensi 40% memiliki tegangan output 200 volt. Jika kalor yang diserap sebesar 500 kJ, berapa daya maksimal outputnya ?
Trima kasih untuk jawabannya
Mohon di cek kembali soal anda, karena mesin Carno t merupakan mesin pemanas, sehingga selama ini belum ada mesin carnot yang mempunyai tegangan output dengan satuan volt.

HOUSE HUSBAND’S HEART RISK
HOUSE HUSBAND’S HEART RISK
Most people assume that life in the rat race is bad for your health. But reversing the traditional gender roles, being a house husband is a stressful business, according to the latest research by American scientist. By giving up their jobs in order to become house husbands, men increase their risk of heart attack or coronary disease by as much as 82%, according to research based on 10 year study of 2,500 people in Boston, USA.
Accoding to Dr. Elaine Eaker, the key to the problem is that some men became stressed about performing a role not traditionally assigm to them by society. Men who stays at home tend not to have the same levels of support from friends and family as women do the same.
Jack O’Sullivan, of the Father’s Direct, was quoted as saying: “Society expects the main career should be a woman and society is structured around that. Day care is called mother and toddler groups and some men feel awkward about belonging to those groups.
Professor Gary Cooper, a psychologist at the University of Manchester, said many men tend to underestimate the task of caring for a family. He said “Most men think being a house husband involves putting on a bit of washing, taking the kids to school and then putting their feet up with a cup of coffee.
They are crazy. Most men are not used to performing a variety of activities simultanously – the kind of multi-tasking which is second nature to most women.
It is estimated that men have taken over the main homemaker’s role in one in seven homes, as increasing numbers of women become the main breadwinner. The study also found that women in high-powered jobs were more likely to develop heart disease than those in more junior positions.

In Hong Kong, the students are not always able to answer questions about their country. Although Hong Kong is their country, they have had little opportunity to go on excursions. Most of them cannot afford the time or money needed for such trips. Since, they do not know much about Hong Kong’s history and its culture, they have always had to write to the Hong Kong Tourist Association for information.
To give such students sound knowledge about Hong Kong, The Tourist Association decided to start the student ambassador programme. The programme has been carried out for eight years. Young men and women who are going overseas for further studies are selected to undergo a special course dealing with the history, culture and lifestyle of Hong Kong.
Through visits factories, government departments and other places of interest, the young people receive ample information which will enable them to answer a wide range of questions asked by persons abroad.
