Today I would like to comment about some information I get from the net.
It is about "SAKURA; the nice and beautiful flowers". So the topic is "Does Sakura is a National Flower of Japan?"

So, just now I know about that, but still it is not too clear for me.
However, I would like to share this information. Not too much but at least a bit.

As I read, it stated that the cherry blossom is the national flower of Japan .Cherry blossom or well-known as "sakura" or "sakura tree". Sakura, together with Krisan flower, are Japan national flowers which rising in the spring season, around early April until last April.

Sakura can be seen everywhere in Japan. We can notice it in various consumer goods, including kimono, writing tools, and kitchen tools. Sakura is a metaphor for uneternal characteristic life and because of that, sakura become a symbol of Japan arts and has a relation with samurai and kamikaze.

I had went to Tokyo, Japan on November 2005, and I had such a nice view of this flower-"Sakura".
The colour of that flower is light pink. Now, I get new information about this flower. The colour is not only pink, but it depends on the species itself. There are white with little pink, pink, young yellow, young green, flame red.

Dearest friends and anyone who read this comment that I post, I want to let you know that the name of "Sakura" comes from these two separable words. Sakura word is come from “Saku” word (means blossom in Japanese) added by end form that describe plural forms “ra”. In English, Sakura flower is called cherry blossoms.

This flower is very famous because during Chinese New Year, there is a lot of this fake flowers at Pavilion. In addition, there is a song title “Sakura” by Rossa who is an Indonesian Singer.

How to style your hair?
There are some step to style your hair.

-Firstly, ask all of the people you know that have great hair where they get it styled. Just say you like their hair and want yours to be more like it. They will be flattered, for sure!

-Flip through a cool magazine for inspiration on a great hairstyle. Cut out at least 2 pictures of the hairstyle you want and take it into your fabulous hairdresser! Go for a sweeping side fringe and textured layers. Make sure it's a big enough change for people to notice, otherwise it's a waste of money.

-Now, the tools! You have a great cut now, but your hair is frizzy or just plain flat. To fix all these problems, you need a multi-styling hair straightener.Here the right way to straighten: Wash your hair with your shampoo and conditioner, then add in your hair drying product. Then, when your hair is completely dry, straighten it and add your serum. If your hair is dead straight, you can use it to create texture and LIGHT waves. A good hair dryer is also needed. The ones with diffusers are the best, because they will leave your locks sleek and smooth.


-Style your hair naturally. It's easiest if you don't try and change your natural hair. If you have curly hair, style it! curly hair can be beautiful. just do what you feel is great to your appearance whether it be spicing it up with curls or straighting with clips! have Fun with it.

Lollipop or candy is one of my favorite snacks. So, today I will discuss an article that I read about candy. Candy is a confection made from a concentrated sugar in water which flavoring and colorants are added. Candies come with variety colors and have a long history in popular culture.
The word candy comes from Arabic word which is ‘qandi’, getting from Parsian qand, meaning sugar. Candy is a wide category that includes candy bars, chocolates, licorice, sour candy, salty candy, tart candies, hard candies, marshmallows and more. In Australia and New Zealand, candies are commonly usage.
Boiled sugar flavored candy is normally referred as ‘stick of rock’ or simply rock and come in many variety with common trend which have a special flavor and so colorful. The popularity of rock sticks had led many inventive application and skill has been taken to made lettering which appears throughout the entire stick is eaten. The ‘stick of rock’ also provided an easy to consume product with some medicinal benefit such as sore throat.
In conclusion, although candy or lollipop is very tasty but there are some bad effect on it. The bad effect is it may effect on your health which may lead to damaged teeth. So, you must control your diet and don’t take candy too much.

Stress..Resolve it now..
I have read an article about how to manage stress. Stress is just like diseases. It spread to everyone without warning. From my experience, as a student I also might be stressed and mostly it happen when I got to do a lots of assignment I a mean time. Stress is the symptoms and effect of stress includes feeling tense, trapped, keyed up, nervous, not able to concentrate. On the health front stress can mean headaches, exhaustion, and the most famous is high blood pressure. To avoid from this diseases is to have a well balanced lifestyle. You can manage it by healthy diet and try to find out an idea to be more relaxed that work for you. Beside that you also must control your breathing. Maybe its sound funny but with the better breathing, your body automatically will feel easy going and relaxed. When you in mood on stress try to get you’re breathing into a comfortable rhythm and breathe in and out for the same length of time, say for a count of 3 or 4, until you begin to feel calmer. Food was the main thing. The benefits of a balanced diet are well known - everything in moderation is currently a fashionable view with an emphasis on fruit, vegetables, whole grains and pasta. Always remember you can’t be perfect. When we under stress, we always blame our self. So, it’s totally not good. Try to convert that anxiety into some form of action which will help you to feel much more positive. For more techniques, you can serve this web.

Dengue Fever.

Today I had read about Dengue Fever. Dengue fever and dengue hemorrhagic fever (DHF) are acute febrile disease, found in the Africa, and caused by four closely related virus serotypes of the genus Flavivirus. It is also known as break-bone fever. Unlike malaria, dengue is just as prevalent in the urban districts of its range as in rural areas. Dengue is transmitted to humans by the Aedes aegypti or more rarely the Aedes albopictus mosquito, which feed during the day.
Signs and Symptoms.
This is manifested by a sudden onset of severe headache, muscle and joint pains (myalgias and arthralgias - severe pain gives it the name break-bone fever or bonecrusher disease), fever, and rash. The dengue rash is characteristically bright red petechiae and usually appears first on the lower limbs and the chest; in some patients, it spreads to cover most of the body. There may also be gastritis with some combination of associated abdominal pain, nausea, vomiting, or diarrhea.
Patients with dengue can pass on the infection only through mosquitoes or blood products and only while they are still febrile.
The classic dengue fever lasts about six to seven days, with a smaller peak of fever at the trailing end of the disease (the so-called biphasic pattern). Clinically, the platelet count will drop until the patient's temperature is normal.

Pevention.
Vaccine development.

Until this time, there is no commercially available vaccine for the dengue flavivirus. However, one of the many ongoing vaccine development programs is the Pediatric Dengue Vaccine Initiative which was set up in 2003 with the aim of accelerating the development and introduction of dengue vaccine(s) that are affordable and accessible to poor children in endemic countries.

Mosquito control.
Primary prevention of dengue mainly resides in mosquito control. This method proved can reduce dengue fever. The other two methods is larval control and adult mosquito control and Larvicide treatment is another effective way to control the vector larvae but the larvicide chosen should be long-lasting and preferably have World Health Organization clearance for use in drinking water. For reducing the adult mosquito load, fogging with insecticide is somewhat effective. Prevention of mosquito bites is another way of preventing disease.

DEJAVU
A few days ago, I read a script entitled “Bukan Dejavu” a masterpiece of Ismail Kassan. This play has been staging for three times, twice at Auditorium Tuanku Abdul Rahman, Malaysia tourism Centre (MTC) (23 - 30 October 1999 and 24 - 29 January 2004) and the last play was at Istana Budaya (10-19 September 2004). The strong storyline was a major factor of being replayed this play for the third time besides the semi-humor element which attracts the audience. Through this staging, we’ve learned from Yanto and Narti, the Indonesian immigrants, that we should be grateful to be a Malaysian, could finish our study and get a better job in our own country. Unlike us, Yanto had to quit his Law studies because of poverty and his wife Narti, a graduate of Agriculture at Universitas Bogor couldn’t find a job in her own land. Not only that, from Nora we learned to respect other people no matter what is their status and occupation. These people are independent and because of their dignity as a civilized people, they have never given up hope for a better life even though their job have being under estimates by the public. Based on the lessons and values from the play, Kumpulan Teater Senandika UMP is honoured to stage Bukan Dejavu to all UMPians in the future. I hope when we play Bukan Dejavu, people will come to see and can get some values from the staging. I would like to stress here that theatre is not immoral because besides having the entertainment value, theatre also give the lessons to the audience.

Leadership? I know, sometimes some people will said that this is quiet boring issue. But, that we relize that leadership is very important in order to guide our target of life. Before, I proceed to the essential of leadership, I just want to give the defination of leadership.Leadership has been described as the “process of social influence in which one person is able to enlist the aid and support of others in the accomplishment of a common task”. A definition more inclusive of followers comes from Alan Keith of Genentech who said "Leadership is ultimately about creating a way for people to contribute to making something extraordinary happen". Students of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence among others.

As a student, leadership is very important tu us. Sometimes, people will give us to lead the group projects or programs. So, as a leader, we shoul know our responsibility and roles in order to make sure that the programs or group projects that we handle will go smooth. so, that is the platform for us to show our leadership.Besides, we also can involve in some organization such as MPP or other else in order to improve our leadership skill.

http://www.nst.com.my/Current_News/NST/Monday/Features/20090201213629/Article/indexpull_html

A new collection of the Anagram canvas bags from the prestigious 160-year-old House of Loewe.
Featuring the brand’s famous logo made up of four intertwining “Ls” in a graphic repeat, this black and grey canvas range boasts an outer body of lightweight, highly resistant and sturdy material that has been coated with a refined, woven texture.
Made in Spain with Loewe’s outstanding reputation for fine workmanship, every detail and hardware element, from its signature padlock to the smallest rivets, has been finished in a specially created rich gold hue.
Each piece is also trimmed with the finest cowhide leather and comes with a refreshing absence of lining to create the suppleness of the woven canvas.
This coated canvas line comprises bags for men and women, travel luggage and small leather items including designs inspired by the Loewe icon — the Amazona bag such as the Weekender bag.
This is the debut collection of the canvas line from Loewe’s new creative director Stuart Vevers, the former “It bag” designer of Mulberry.
His new take on the iconic Anagram by arranging it in a graphic manner, and his re-proportioned attache case and streamlined Weekender bag, for example, are refreshingly modern and embody the 21st-century interpretation of Loewe’s heritage.
This collection can get it at Loewe boutiques in Suria KLCC, Starhill Gallery and Isetan, The Gardens in Kuala Lumpur.

Assalamualaikum,

In this first entry i would like to share about car which is Lamborghini.

Lamborghini had been evolution from time to time.It is very exclusive and smart car for rich people.The production of this Lamborghini is limited and will come out when someone or company want it.It so EXPENSIVE.

The speed of Lamborghini can compete Ferrari which is up to 300km/h.You can imagine how fast it is.

The interior inside it also exclusive than we can imagine.It had leader seat with something else that i can't explain here.

For the safety,Lamborghini give the first class safety.If you drive a normal car up to 200km/h and crash,what will happen to you??Maybe you will die immediately but in Lamborghini,you will survive even thought you drive up to 300kn/h.

It is all because the hard body of Lamborghini car compare to other car.Of course the car will damage but you will survive.

GUNDAM is an anime series that originaly come from japan.What does gundam have that interest me and other?First of all,gundam is a gigantic mechanic robot that need a driver to move the robot or gundam.The interesting part is the design of each gundam are very unique and will make you stunt if you see the amazing created gundam ever build.Gundam became a collective term for 7 different time lines, all featuring their own story-lines, with a few common denominators and war machines called Gundam.Gundam is said to have pioneered the real robot era of mecha anime.Unlike its super robot cousins, Gundam attempts at realism in robot design and weaponry, as well as the thematic and ethical roles of the robots themselves. Zambot 3 was an earlier program by Tomino, where he began developing the ideas in "Gundam".Academic fields in Japan also view the series as a good inspiration in research fields. The Gundam academy, or officially International Gundam Society is the first academic institution based on an animated TV series.In 2009 the Gundam franchise will celebrate its 30th anniversary. A new series based on Universal Century will be announced as part of the anniversary.hope we can celebrate it together.

Researchers in the United Kingdom found that test subjects who doodled while listening to a recorded message had a 29 percent better recall of the message's details than those who didn't doodle. The findings were published in Applied Cognitive Psychology.


"If someone is doing a boring task, like listening to a dull telephone conversation, they may start to daydream," study researcher Professor Jackie Andrade, of the School of Psychology at the University of Plymouth, said in a news release issued by the journal's publisher. "Daydreaming distracts them from the task, resulting in poorer performance. A simple task, like doodling, may be sufficient to stop daydreaming without affecting performance on the main task."


For the experiment, a two-and-a-half minute listing of several people's names and places was played for test subjects, who were charged with writing down only the names of the people said to be attending a party. During the recording, half the participants were asked to simultaneously shade in shapes on a piece of paper without attention to neatness. Participants were not told they were taking part in a memory test.


When the recording ended, all were asked for the eight names of those attending the party as well as eight place names mentioned in the audio. Those asked to doodle wrote down, on average, 7.5 names and places, while those who didn't doodle listed only 5.8.


"In psychology, tests of memory or attention will often use a second task to selectively block a particular mental process," Andrade said. "If that process is important for the main cognitive task, then performance will be impaired. My research shows that beneficial effects of secondary tasks, such as doodling, on concentration may offset the effects of selective blockade."


In everyday life, Andrade said, doodling "may be something we do because it helps to keep us on track with a boring task, rather than being an unnecessary distraction that we should try to resist doing."

Computer network

A computer network is a group of interconnected computers. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of some types and categories and presents the basic components of a network.

Connection method

Computer networks can also be classified according to the hardware and software technology that is used to interconnect the individual devices in the network, such as Optical fiber, Ethernet, Wireless LAN, HomePNA, or Power line communication.

Ethernet uses physical wiring to connect devices. Frequently deployed devices include hubs, switches, bridges and/or routers.

Wireless LAN technology is designed to connect devices without wiring. These devices use radio waves or infrared signals as a transmission medium.

[edit] Functional relationship (Network Architectures)

Computer networks may be classified according to the functional relationships which exist among the elements of the network, e.g., Active Networking, Client-server and Peer-to-peer (workgroup) architecture.

Types of networks

Below is a list of the most common types of computer networks in order of scale.

Personal Area Network (PAN)
Local Area Network (LAN)
Campus Area Network (CAN)
Metropolitan Area Network (MAN)
Wide Area Network (WAN)
Global Area Network (GAN)

Internetwork

Main article: Internetwork

Two or more networks or network segments connected using devices that operate at layer 3 (the 'network' layer) of the OSI Basic Reference Model, such as a router. Any interconnection among or between public, private, commercial, industrial, or governmental networks may also be defined as an internetwork.

In modern practice, the interconnected networks use the Internet Protocol. There are at least three variants of internetwork, depending on who administers and who participates in them:

* Intranet
* Extranet
* Internet

Intranets and extranets may or may not have connections to the Internet. If connected to the Internet, the intranet or extranet is normally protected from being accessed from the Internet without proper authorization. The Internet is not considered to be a part of the intranet or extranet, although it may serve as a portal for access to portions of an extranet.
