Laser tooth whitening explained
No longer science fiction
Dr. Varaphan Unachak, MD and CEO of Chiangmai Ram
Hospital, explains that ‘laser tooth whitening’, even though it might
sound dangerous, has nothing to do with science fiction or ‘shooting’
your teeth white but is on the contrary a soft way to remove stains, lighten
pigmentation inside your teeth and remove tea, coffee and nicotine stains.
It is a method by which qualified cosmetic dentists can brighten your smile
in less than two hours.
Varaphan Unachak, MD, CEO of the Chiangmai Ram Hospital Chiang Mai.
Dr. Varaphan has noted the different age groups that have
this treatment carried out. “It is either the young and hip client in the
early 20’s or business people over 40, who want to get rid of stains and
just brighten their days. It can be done comfortably in a relatively short
time and takes not longer than a visit to the hair dresser, but with an
effect which lasts up to three years, depending on the individual
Side effects are few, according to Dr. Varaphan, though
there may be a little discomfort and dryness of the throat after sitting in
the dentist’s chair for over an hour with mouth wide open.
Watching what you eat, stay away from things which stain your teeth, stop
smoking, brush your teeth twice a day for at least two minutes with a
fluoride tooth paste and have a dental check-up at least once a year.
The Doctor's Consultation: Dengue Fever - again and again!
by Dr. Iain Corness
Despite my pleas (and those of the Public Health
Department), Dengue Fever and its potentially fatal variant, Dengue
Haemorrhagic Fever (DHF) is still with us. The latest figures have now
prompted me to repeat my advice on this subject. If you remember reading about
it before, I apologize, but the subject matter is very important. This is an
important ailment that can be avoided.
However, first you should understand a little more about
Dengue. It was first described in 1780 by a Benjamin Rush in Philadelphia (so
it didn’t start here), when the name Break Bone Fever was applied, with the
symptoms of pain in the bones and rise in temperature. The name “Dengue”
came in 1828 during an epidemic in Cuba. The new name was a Spanish attempt at
a Swahili phrase “ki denga pepo” which describes a sudden cramping seizure
caused by an evil spirit! Let me assure you that the local brand of Dengue
Fever owes nothing to spirits, evil, bottled or otherwise.
Like Malaria, the virus is carried by mosquitoes, this time
by one called Aedes aegypti. The virus itself is related to Japanese
encephalitis, Murray Valley encephalitis and Yellow fever, and there are four
“serotypes” or subgroups of it.
The mosquito lays its eggs in water containers, preferring
the clean water found in water tanks and pots, in the saucers under pot plants
and even under the pet’s food dish. Inside discarded car tyres are another
favourite spot. These mosquitoes are not of the adventurous type and feed
during the day and spend their time within 200 metres of their hatchery.
Consequently, the eradication of any local breeding areas becomes very
important towards maintaining your own health, as you can see. Keep your home
free from lying water for a radius of 200 metres and you’re looking good!
Simple Dengue (if you can call it that) has an incubation
period of around four to seven days and then the full blown symptoms of high
fever and headache begin. The headache is usually behind the eyes and is made
worse by eye movement. From there the pains progress to the limbs with acute
muscle pains, which gave it the old name “Break Bone Fever”.
Interestingly, some patients complain of a metallic taste in the mouth.
(Please don’t ask - I have no idea why!)
On the other hand, Dengue Haemorrhagic Fever can certainly
be fatal! It appears that Serotype 2 may be the culprit here, but does not
usually produce DHF unless you have been previously bitten by types 1, 3 or 4.
In addition to the symptoms of Classical Dengue the skin begins to bruise very
easily as the blood haemorrhages into the skin. Children are also more
susceptible to this than adults. This also becomes much more of an emergency
and is best treated in the Intensive Care Unit (ICU) of your favourite
With our ability to treat the viral ailments being very
limited, the defence against the Dengue virus lies in the preventive measures.
The other precautions are to wear long trousers and long sleeved shirts,
especially at sun up and sun down, when the mosquito is at its most ravenous.
The other factor to remember is “D” for Dengue and “D” for DEET. DEET
is the magic ingredient in mosquito repellents, so when you go to buy some,
check the label - if it has DEET, then get it. And then remember to use it!
This is a crazy time in my life and I am all at sea. I have provided for
my wife for the past 16 years. She has never had to want for anything. I
am a model husband, good looking, never play up, only drink in moderation,
don’t smoke, in perfect health, a witty intelligent companion, and I
have always been considered by everyone as a “good catch”. This week
she calmly announced that she wants a divorce. I can’t get it out of her
as to why - just that she wants a divorce. Why, Hillary, why?
I would say that the reason could just possibly be that after the same 16
years she has woken up one morning to find she was lying beside an
impossible self satisfied, pompous and arrogant twit. If you were my
husband, I would have divorced you too. But it wouldn’t have taken me 16
years to waked up! As far as being all at sea, don’t worry, your ship
will wash up somewhere. Your type always does.
Where would you suggest I take my girlfriend for a romantic night? I
intend to propose to her then, so want the surroundings to make it an
evening to remember. You must have all sorts of rendezvous that you could
You didn’t say in your letter what it was that you wanted to propose to
the young Juliet. Marriage, m้nage a trois or a dirty weekend in
Tianjin? Your email also gave me no indication of where you are. What’s
the use of me suggesting somewhere that’s 1,200 kilometers from where
you are? If you are so indecisive and wishy-washy as this all the time, I
hope she says No! to all three of your proposals.
I think your advice is stupid. What right have you got to tell people what
to do? Are you qualified to be handing out all this sort of silly
nonsense? Why don’t you go back to your dog-house or wherever you came
To be perfectly frank, which I’m not since I’m a Hillary, I have as
much right as you have, my Petal. Since you are the one with a bone to
pick, perhaps it is you that should be living in the kennel? Woof! Woof!
I seem to have got myself into a little bit of hot water here, and need
some words of advice from a ‘senior’ person such as your good self. I
am a young single man, and considered to be not bad looking. My problem
comes from one of the girls I have met recently. She rang me at work the
other day and asked if I could come over and see her at the new bar she
was working in. I have to admit I did not remember her from her previous
bar but was embarrassed so I agreed that I would. Because I was not sure
which lady this was, I never went, but now she is ringing me up every day
and everyone in the office is laughing. What should I do? How can I tell
her it isn’t a good idea to ring me at work in a crowded office? Any
You are far too “earnest” for your own good, my Petal! You have
brought all this on your own head, haven’t you. If you don’t want
anyone to ring you up, then don’t give them your telephone number! She
didn’t dream up your number or get given it by the fortune teller, did
she? It’s quite simple, if you don’t want a girl to ring you at work,
then don’t give her your business card. If you feel the need to chat her
up on the phone just give her your mobile and tell her what hours to ring
you. The girl isn’t stupid. You are. And thanks for calling me a
‘senior’! Let me assure you Hillary is not eligible for any pension.
You are often telling people that they should learn Thai if they are
living here for some time. I have retired here, but at 65 years of age, I
find it very difficult to learn a new language at my time in life. Is
there any quick way of doing this, or do you have any special tips for
people trying to learn this impossible Thai language?
First let me say congratulations, my Petal! It’s about time some of the
people out there realize that this country is called Thailand and the
people speak Thai. There are many ways to learn the language. There are
the set courses offered by language schools all over the country. They are
used to people at your stage in life and will tailor a course to suit you,
so don’t feel embarrassed. Second there is the ‘total immersion’
method. This is where you take yourself off to an up-country village,
where nobody speaks English. You have to learn to survive! I have been
told that by six weeks you will either be talking reasonable Thai or will
have gone stark raving mad. However, it is still the quickest way to pick
up a language. You will probably have picked up a small language teacher
Camera Class: Henri Cartier-Bresson’s
final ‘decisive moment’
by Harry Flashman
Henri Cartier-Bresson, the originator of the
phrase in photography, “The Decisive Moment”, has just died, a few weeks
before his 96th birthday. However, he will be remembered for his contributions
to photography for ever. However, despite his fame and notoriety, he was never
one to look for publicity. His photographs perhaps now will speak for
was born in France in 1908 and initially studied painting, following much of the
Surrealist school of thought of the time. However, by the time he was 22 years
old he had dropped art for photography, but began to apply the art concepts he
had been exposed to towards photography.
One of the factors that allowed Cartier-Bresson to do this
was the advent of the small portable cameras, such as the Leica, which was to
become Cartier-Bresson’s favourite instrument. It was this portability that
allowed Cartier-Bresson to become ‘one’ with the subject. He believed that
the photographer had to become part of what was going on, and after becoming
‘in tune’ with the subject, it was then possible to capture the essential
moment, the very essence of the event. This was explained by Cartier-Bresson in
the foreword to his book, published in 1952, “Images a la Sauvette” (The
Decisive Moment). He called it “The simultaneous recognition, in a fraction of
a second, of the significance of an event as well as the precise organization of
forms which give that event its proper expression.”
With this concept and the portable lightweight camera,
Cartier-Bresson was to become one of the principal ‘street’ photographers. A
true journalist with a camera - a photo-journalist. He would record not just a
parade, but also the people watching the event, and their reactions to the
Take a look at the classic photo to illustrate the decisive
moment. The shot was taken in 1932 at the Place de l’Europe, where the
marooned man has finally realized that there is no way out, and having made the
decision, launches himself off the ladder. That split second, that decisive
moment caught by Cartier-Bresson in such a way the viewer can feel the moment
still today, 72 years later.
His work took him across Europe. He recorded the Spanish
Civil War in the 1930’s and then WW II, but was finally captured and he became
a POW. He escaped three years later, and was there to record the liberation of
Paris from the Germans.
Of course, he was by that stage becoming an icon, and in 1947
joined forces with two other ground-breaking photojournalists, Robert Capa and
David Seymour to form the Magnum agency. Magnum became famous for its news
photography. For Cartier-Bresson, news was much more than the photo-journalists
were showing. It was necessary to get behind the scenes.
Cartier-Bresson and his confreres forged a name for hard
hitting news photography. Cartier-Bresson spent almost 20 years there, covering
Mao Zedong’s victory in China and the death in India of nationalist movement
leader Mahatma Gandhi.
Regarded as one of the pioneers of photojournalism, his
pictures now hang in art galleries around the world, with a retrospective in
Europe to be extended to allow more visitors the chance to view his work.
Friend and fellow photographer Lord Snowdon paid tribute to
him saying, “He was brilliant. I will miss him very much. I don’t think
he’d like his work to be called art, he would like to be remembered as an
anonymous figure. His books record moments that can’t be captured again.”
Again that concept of the ‘decisive moment’.
French President Jacques Chirac said his death was a major
loss to his country. “With him, France loses a genius photographer, a true
master, and one of the most gifted artists of his generation and most respected
in the world,” he is reported saying.
Not just France, but the world has lost a photographer who had vision and the
ability to record his vision in a way the world could understand. The decisive
moment will always belong to Henri Cartier-Bresson.
Dogs - Man’s best friend: Development of dog breeds
Although domestication from wolf to dog has taken place
over a much longer time, dogs have existed in our homes for centuries. The
first known clear dog-like wolf living and loved by men dates back about
dog was not bred for working purposes.
One of the first images of dogs found on cave paintings
in Spain is over 12,000 years old. 7,500 year old Egyptian pottery contains
images of Saluki-like dogs. Later on their wall paintings and hieroglyphics
showed also spitz and terrier type dogs. 4000 year old Babylonian sculptures
show Mastiff type dogs. In China written records from over 4000 years reveal
that dog trainers and kennel masters kept large groups of dogs. So is the
“Fu” or ‘Lion Dog”, an ever-recurring symbol of good fortune and
happiness in Chinese culture. And in Mexico a 100 BC terracotta vase was
found in the form of a dog look-a-like, the present Mexican Hairless Dog.
Dog breed groups have evolved in several parts of the
world independent from each other. It is believed the African Basenji, the
Arabic Saluki, the Chinese Pekinese, the Australian Dingo and the majority
of the European dog breeds descend from the Indian Wolf. The Japanese Wolf,
or “Shamanu”, is probably the ancestor of most Japanese dog breeds, such
as the Akita and the Shiba Inu. And the European Grey wolf is the ancestor
of many breeds belonging to the Spitz class. The now extinct Kenai Wolf from
Alaska is thought to have had genetically influence on the Alaska Malamute,
and the Mexican Canis lupus baileyi on the Chihuahua and Mexican Hairless
For centuries dogs were mainly bred for their working
purposes, such as hunting, guarding and herding, but also as a natural
heater! But the hundreds of different breeds, as we know them today, are
only from the past few hundred years. This kind of highly selective breeding
started during the Industrial Revolution when cities developed and urban
people became more and more cut off from natural world. Through a dog, this
was counteracted. As in the cities the original tasks of the animals were no
longer needed and cruel sports such as dog fighting and bull baiting became
forbidden, dog lovers needed to find some new roles for their pets. And so
the first dog beauty competitions were arranged in pubs in the eighteenth
century. Within a century this had lead to fully organized dog shows with
fixed standards, and pedigree dog breeding, keeping and showing.

Dr Byte's Computer Conundrums
by Dr Byte, Citec Asia
I was reading a very interesting article about why we
shouldn’t blame Microsoft entirely for the problems we face with badly
developed software. Microsoft has carried the blame for many things that go
wrong, but this also explains some of why we should also consider another
culprit. Our tech colleges and universities.
While I was reading this article, my mind was saying - well
that’s so obvious! and Yes! and so on, as I read each statement. I want to
share some of this with you.
Think about this. How many “bugs” (problems) have been
discovered in current versions of commercially oriented software (e.g. word
processors, web browsers, databases etc) by the vendor? I think you’ll find
the answer is somewhere between none and very, very few. Compare this with the
number discovered by customers (you and me), and unfortunately “hackers” in
Once a product is released, the software vendor only wants to
focus on the next release. With any luck, there will be lots of reasons (bugs!)
for customers to want, or need, to upgrade to the next version. Best of all, the
vendor doesn’t even have to go looking for these bugs - everyone else is doing
the job for them. The business model for most software vendors not only
encourages this behaviour, it actually relies on it. Why on earth should a
vendor go looking for bugs in current versions? There’s no money in that. In
fact, it pays to write poor code, just not too poor.
Digging a little deeper, what motivates vendor senior
management. Senior management are rewarded by how well they achieve the business
model objective. Mid-level managers and software developers are pressured from
above to create the best software possible and still meet release deadlines that
often have everything to do with marketing requirements and not coding
requirements. Programmers are usually rewarded for the quantity not the quality
of code. After the programmers have finished, the beta version is passed to
testers. The focus of testing is to prove that the programming does what is
claimed it will do. Not enough time, if any, is spent proving that it doesn’t
do what it shouldn’t, security holes is one example. There’s also an implied
pressure on the testers - don’t find too many bugs - you’ll make the
programmers look bad!
The new software will be developed in accordance with
internal design requirements, tested against these requirements and marketed by
people who turn obscure facts into major features. Have you ever tried telling a
marketer about limitations? So far, testing has been done by people with a
vested interest in not finding bugs. Last of all, the real expert gets involved.
The user (you and me).
Let’s step back a bit more: what about the programmers
themselves? Teaching institutions turn out programmers who are very good at
writing “good enough” code. After all, if it’s good enough to get a pass,
what more do they need to do? These institutions have to produce graduates who
are well rounded and able to enter a variety of IT careers; there’s
insufficient time to do much else.
How many of the best hackers have attended university? Most
of them probably aren’t even old enough! I think great programmers are usually
self-taught and often come from a hacking background. If you’re good at
finding vulnerabilities in someone’s software, you’re probably going to
understand how your own program can be attacked, and can then write code taking
that in to account.
Lastly, there is an interesting article by a senior scientist
at TruSecure, in which he argues that programmers are largely victims of the
tools they use. Most tools are intended as “rapid development environments.”
However, the faster you develop software, the harder it is to debug, especially
for security. He also notes that when the tools try to promote security-aware
programming, the programmers do their best to defeat the tools!
Obviously, the principal reasons software development is
rushed is to beat the competition and make money - to be sooner on the market
and to be more feature-rich. Think about it. How happy would you be if the
engineers designing a new suspension bridge were rushed in their design and
construction work, only to find they needed to release a second version one year

Beer and More: Beer and Beauty
by Karl Eichhorn,
Chiangmai Malting product manager
It is popular notion, that beer influences positively the
appearance of skin and hair, and this by its intake as well as its external
application. Beer beautifies.
applied, beer does more than any shampoos can. Beer provides strength and makes
hair lavish and bouncy. The secret of this reaction is the beer’s astringent
qualities, resulting in the contraction of individual hairs. This in return
provides a more solid texture and increases the volume of the hair.
Egyptian women, reported the Roman writer Pliny 2000 years
ago, use the foam of beer to improve their complexion. What persuaded them to
choose beer and not another beverage is not known until today.
Modern cosmetics are unthinkable without the utilization of
beer. Creams are already in the markets which take their effectiveness from the
high vitamin content of beer-yeast. Unhappy teenagers in puberty with their skin
problems, are profiting from these creams. Next time you walk through one of the
department stores cosmetic region check it out yourself.
But there are still people out there who are non-believers. For those I will
end my weekly beer enlightening with a ‘science joke’: “Yesterday
scientists revealed that beer contains small traces of female hormones. To prove
their theory, the scientists fed 100 men 12 pints of beer and observed that 100
percent of them gained weight, talked excessively without making sense, became
emotional, and couldn’t drive. No further testing is planned.”
Money Matters: Scott Campbell’s views on Thailand
(written at the start of May 2004)
MBMG International Ltd.
Continuing our mini-series on the views imparted by Scott
Campbell, the portfolio manager whose ‘Growth Fund’ has been judged by
S&P to be the best in its sector for the last 6 years, during his first
ever visit to Bangkok, last month we turn our attention, once again, to
It is that time of the year when Warren Buffett reveals
the annual results of his company, Berkshire Hathaway and also provides his
insights into current trends and investment issues. Consider the facts and
it is easy to understand why so many wait in anticipation for this
commentary and his legendary annual general meeting in Omaha in May.
Over the past 39 years book value of Berkshire has
increased 22.2% compounded annually. NAV per share was US$19 in 1965 and is
now US$50,498. Shares trade at nearly 2 times book or US$100,000 per share.
Total results versus the S&P500 are awesome since 1965, but probably
more impressive to me is the out performance in tough times.
The table above depicts Berkshire’s annual percentage
change in per share book value versus S&P500 with dividends reinvested.
The startling historic fact is that intrinsic value has somewhat exceeded
the 22.2% pa book gain? Enough of the history, everyone knows Buffett is a
GURU. Where is he positioned today and what are his current views?
Berkshire has 4 main investment sectors, insurance,
operating businesses, finance and common stock investments. When valuations
are similar they strongly prefer owning businesses to owning stocks and the
latter has decreased in percentage as stocks become the far more expensive
choice. In recent years they have found it hard to find significantly
undervalued stocks with 1) favourable and enduring economic characteristics,
2) talented and honest management and 3) are available at a sensible price.
2003 was a terrific year for their insurance businesses.
They produced an underwriting profit of US$1.7bn and had the use of US$44bn
of “float” assets. GEICO continued to prosper and the reinsurance
company, General Re looks to have turned the corner. Following on from last
year’s thesis on derivatives, General Re is still trying to exit all
derivatives activities since 2002. It has cost US$173mn in 2002 and US$99mn
in 2003 to shrink this business but more importantly in early 2002 it had
23,213 outstanding contracts with 884 counterparties (some having names that
Buffett couldn’t pronounce let alone evaluate creditworthiness).
Despite a concerted effort, they still have 7,580
outstanding contracts with 453 counterparties! These losses have come in a
benign market; all contracts were previously valued market to market and
without any major credit loss. Buffett cautions again on the shenanigans of
derivative accounting and what is lurking in the undergrowth, indeed the
more you learn the less you know from disclosure documents.
The scary thing about all this is the sheer gigantic size
of the unregulated OTC derivatives market place and that General Re has
taken these hits in an orderly market. What happens if a financial crisis
forced a number of derivative dealers to cease operations simultaneously?
Reported profits are illusionary and Buffet notes that the cash needed to
prop this business up in the tough times, would be exactly the time they
wanted to deploy that very cash into other assets at huge advantages. They
remain convinced that derivatives are financial weapons of mass destruction,
carrying dangers that, whilst now latent are potentially lethal.
All Berkshire’s boring businesses performed well in
2003 and they made a major acquisition in manufactured housing, brought a
distribution business from Wal-Mart and continue to grow MidAmerican Energy
Holdings. Existing businesses such as Flight Services, Shaw Industrial and
Fruit of the Loom are in good shape. The common stock investment portfolio
remains dominated by Coca-Cola, American Express and Gillette and they are
neither enthusiastic nor negative about the portfolio they hold.
Buffett is annoyed that he didn’t sell several of the
larger holdings in The Great Bubble. In 2002 Berkshire purchased US$8bn of
junk bonds or high yield debt because they felt it was cheap. He notes that
the pendulum has swung quickly and this sector looks decidedly unattractive
to them. Yesterday’s weeds are today being priced as flowers and an exit
strategy is in progress.
Finally, Buffett is critical of US corporate governance, the US trade
deficit, US$, mutual fund directors and un-repenting CEOs. His cash pile of
US$36bn (US$12bn is in foreign currencies for the first time) is only
earning a pittance, but he is prepared to under-utilise capital and be
patient as it is way less painful than doing something stupid. A very wise

How did you spend your summer holidays? Probably like every
other normal people with sunbathing, swimming, and enjoying yourself. Maybe a
few of you went to a holiday club or somewhere where you could do a lot of
where I spend my holidays this year. We were 144 kids and had our own kids club
with lots of things going on all day. One day of the week we had a kids’
night where we performed dances, sketches, an acrobatic show and so many other
things. We practiced two whole afternoons, the, I call them ‘teachers’,
gave us costumes and showed us how to put on stage makeup.
It was so much fun. I wish somebody in Chiang Mai would open
a group like that for children. Adults always think children are too small to
perform but we had 3 year olds who did a flower dance, and they looked so cute.
One was the sun and the others where the flowers, always dancing when the sun
stood up and ‘sleeping’ when the sun left the stage.
I believe we could do something similar in Chiang Mai as
well but once again we need adults for guidance. I mean mums and dads to start,
help and sponsor. May be You could talk to YOUR mom and we children of Chiang
Mai can get a small international theatre group together. Think about it and
may be you want to write to me. See you next week, same newspaper, same page.
