Smart Gadgets are Like Sleeper Cells in Your Kitchen



Most people don't know their gadgets can already talk to one another, and even be controlled remotely by their utility company.
CHRISTOPHER MIMS
Manufacturers are "future-proofing" their appliances with capabilities that are latent -- for now.
If you bought a major appliance in the last three years, odds are it was "smart," even if you didn't know it. Meaning: it probably contains a wireless radio that can broadcast and transmit over a small personal area network, sending out information about a device's status and energy use, as well as receiving commands that alter its behavior.
Many appliances that don't even announce they have this capability are equipped with it, says Mike Beyerle, an engineer at GE whom I recently interviewed about GE's coming Nucleus home energy management system.
"We want to build up a base before we make a big deal out of it," says Beyerle.
It's an intriguing twist on the old business maxim "under-promise, over-deliver." In this case, manufacturers aren't even telling consumers what their devices are capable of because, in part, those abilities are useless without an energy management hub like GE's Nucleus or a utility company's smart meter. (Confusingly, GE appliances that can communicate in this way are labeled "Brillion.")
In both cases, smart appliances must be "bound" to a hub (either an all-in-one hub like the Nucleus or a smart meter itself) in order to communicate with the outside world.
Once a device is hooked up to an energy management system, things get interesting. Did you realize, for example, that your refrigerator's ice maker's defrost cycle can be shifted to another time of day by your utility in order to drive down power use during times of peak demand?
Ditto your clothes dryer. If a user is signed up for a "demand response" program in which they agree to have their energy consumption remotely reduced by a utility in exchange for a lower bill, various elements of a dryer can be shut down. For example, it might be set to dry at a lower heat but for longer, allowing the same level of drying but with less energy consumed.
Consumers in states like California, whose utilities are using so-called "demand sensitive pricing," can also set their appliances to use less power when electricity is at its most expensive. (Usually, in the afternoon on hot days.)
GE's Nucleus won't roll out until 2012, and smart meter penetration is still no more than 25 percent in the U.S. But with the cost of new power plants rising by the day, putting smart meters into homes is more attractive than ever to utilities. Not only do they allow utilities to enroll customers in demand response programs, they also tend to lower electricity consumption overall, because they empower consumers to understand when and how they are using energy.
So do you have a sleeper cell in your kitchen or laundry room, waiting to be activated by the installation of a new smart meter or some other Zigbee-capable device? You may not know until you have the right kind of hub installed -- but some already have a ZigBee label.

NASA Tests a Versatile Habitat for Long-Term Missions



The partially inflatable habitat could be adapted for use on the moon or Mars, or for deep space itself.

Space home: NASA tests a new habitat for astronauts in the Arizona desert.

Despite recent cuts to its manned space program, NASA continues to research ways that astronauts might live safely in space during prolonged missions. The agency recently completed tests of a prototype astronaut habitation unit in the rugged, barren, almost-Martian landscape of the Arizona desert. The habitat could be tested in space within a decade, and might one day serve as a home away from home for astronauts on the moon or Mars.
The tests, completed last month, included sending in crews for overnight stays, and running simulations of work that would be done in a single day.
The current prototype housing unit has a hard cylindrical shell, contains four rooms, two outside additions for dust mitigation and hygiene, and an inflatable component that adds a second level for sleeping and relaxing.
The inflatable loft design was part of a university competition called XHab. The researchers explain that a final design could be fully inflated, or could have a small hard shell inside an inflated exterior. Hard shells, while heavier to transport, are better at blocking dangerous radiation from space.

Inflatable space habitats have been a popular idea since the 1970s, but the new project is the most advanced to date. Inflatable units are a typical option because they offer a lot of volume for the weight of materials, so the cost of getting the housing to space is lower.
The team also tested a prototype robot that could explore the surface of Mars and be controlled by an astronaut from inside the habitation.
"It changes things if you're running that robot in close proximity, versus trying to operate it from Earth with a 50-second time delay," says Kriss Kennedy, project manager of the Habitat Demonstration Unit project. The results were presented this week at the American Institute for Aeronautics and Astronautics (AIAA) Space 2011 conference in Long Beach, California.
The habitation system uses embedded sensors to reduce the need for checkups by crew and ground control. "We are infusing more technologies so that crew wouldn't have to repair the unit if there were a problem. Inside the unit, the electronics can be controlled by iPads and iPhones, allowing the crew to adjust the lights and temperature.
Deep space missions are inherently risky. Radiation from galactic cosmic rays, which can cause cancer, and from solar flares, which can cause quick death, is a serious issue for long-term space habitation. Cargo bags, used to carry loads up to space, could used to change urine into water via a purification technique called forward osmosis and then help pad the walls with water to protect the crew inside.
The unit could be adapted for missions to the moon, Mars, an asteroid, or simply as a free-flying habitat in space. "Different missions require different sizes of habitation," says Tracy Gill, who works within the Space Station Utilization Division at NASA's Kennedy Space Center, because of the different items needed onboard. Within 10 years, the team plans to have a demonstration unit either flying in space or attached to the International Space Station.
Flying habitats need to be easy to repair, says Jeffrey Hoffman, a former astronaut and professor of aeronautics and astronautics at MIT. "Unlike the International Space Station, it won't be possible to send up replacement parts, so local materials will be key," he says.
Daniel Lester, an astronomer at the University of Texas at Austin, says a habitation like the one NASA is testing could be a useful place to house a crew servicing space telescopes, or assembling spacecraft to travel to farther-off places like Mars.

Sharing Gold




Lord Krishna“…a man's pure consciousness is covered by his eternal enemy in the form of lust, which is never satisfied and which burns like fire.” (Lord Krishna, Bhagavad-gita, 3.39)
It’s sad to say, but no amount of distribution of material benedictions will satisfy the soul craving a permanent activity that is coupled with a worthy beneficiary of service, one who can extract the full potential for love found within the heart. The tendency for the giving individual is to provide basic comforts to those who are distressed, but this does nothing to solve the real problem of life, that of the repetition of birth and death. More than just stopping reincarnation, if a distressed person wandering aimlessly for permanent happiness can be given tools and a never-ending project to work on, they can be handed the keys to the mint that houses imperishable transcendental delights.
Why is birth and death important to stop? How do we even know that these occur in cycles? The Bhagavad-gita says so, and since it is the most authorized Vedic text, the information found within can be accepted as fact, especially when received from someone who faithfully follows its teachings. Lord Krishna, the Supreme Personality of Godhead, is the orator of the Gita, and His song is one that has been sung many times over the past five thousand years. Even if we are hesitant to accept the Gita’s statements on reincarnation because of prejudices or boundaries erected through ignorance, we can still take away other precious gems presented by Krishna.
“From the mode of goodness, real knowledge develops; from the mode of passion, grief develops; and from the mode of ignorance, foolishness, madness and illusion develop.” (Lord Krishna, Bhagavad-gita, 14.17)
Lord KrishnaIn one section the Lord tells Arjuna, the direct recipient of the Gita’s teachings, that the senses are very difficult to control, especially since the mind will wander from one place to another. When the spirit soul is placed in an area designated for material activity, the behavior followed can fall into one of three modes: goodness, passion or ignorance. The mode of passion is the one accepted by default by the human being, and it also corresponds directly with the concept of working for fruits and enjoying them. Lord Krishna says that the mode of passion eventually leads to misery, as more and more gains only keep the senses attached to objects that are temporary in both their manifestation and the enjoyment they provide.
What does this mean exactly? An example which nicely illustrates this concept is gambling. The gambler may stop at the card table to only play a few hands, but if he starts winning, he can get hooked to the game. The objective of each game is to win, which is signaled by a payout of some kind. Yet if this payout were the panacea of happiness it was thought to be, what need would there be for further play? As another example, a rich business mogul who makes billions of dollars would seemingly want to rest on his laurels and just enjoy his accomplishments, no? Yet we see that once billions are earned, an even stronger push is made towards increasing that wealth, parlaying your earnings intohundreds of billions.
What drives this chase? Why not just enjoy what you win? The senses are conditioned in such a way that they cannot be satisfied even through constant feeding. Strong desire for the satisfaction of the senses is known as lust, and it is an all-devouring enemy. This point is made by Krishna in the Gita, and it is continually validated in the visible behavior around us. Even though we can see the effects of lust for ourselves without ever having to open a single page of a religious book, the tendency for helping the distressed still follows an erroneous pattern. You see someone down on their luck, in trouble, and you give them some money or some other gift that has an identified monetary value. The idea is that if the sufferer enjoys the gift, their pain will go away.
gamblingBut let’s think about it rationally. If even the gambler and the business mogul aren’t satisfied by heaps of rewards that are earned through personal effort, why would someone be satisfied with something just given to them? More specifically, if we work hard for something, the resulting fruits will be all the more appreciated. The child has no concept of what money is really worth until they actually start working in adulthood. Yet, if even the people who work really hard to acquire their gains remain unsatisfied, how are those who don’t work hard for their rewards expected to appreciate the gifts given to them?
In the childhood years, presents on one’s birthday are sought after and then later remembered. Even Christmas gifts are anticipated and appreciated because the child doesn’t have the money to go out and buy whatever it wants. Moreover, the child tends to have a stronger desire for gifts than the adults do. As the years go by, however, more and more gifts start to pile up from the many birthdays and Christmas holidays. Among the people storing so many presents, how many of them can actually remember who gave them which gift? The gift could even be something that is used all the time, something that is cherished and brings tremendous enjoyment. Despite the gift’s use, who actually donated it and when remain forgotten.
This is a reminder that the senses are like a machine that just gobbles up whatever is thrown its way. And with each new item consumed, the attachment for such objects increases and the level of satisfaction decreases. A person training to run a marathon eventually learns to run a few miles without a problem, even though in the beginning such short distances caused tremendous strain on the body. With sense gratification fueled by constant attention and gift-receiving, the effect is similar, but the consequences are negative instead of positive. In the past we may have lived without so many things and been able to keep the mind satisfied with very little, but with each new gift comes a new attachment, with the requirements for finding a minimum level of satisfaction increasing just a bit more.
What can be done to solve the problem? Renunciation is a good step, as it helps to prevent becoming spoiled. Good parents are keenly aware of the need for not spoiling their children, as they won’t buy gifts for their kids every time they ask for them. But more than just limiting intake of ice cream and videogame playing, the parents make sure that their children have active engagements. This is much more important than simple renunciation or even the giving of gifts. A fulltime occupation that yields the most mature fruits down the road is the greatest gift anyone can give to another person. In this sense we owe a tremendous debt of gratitude to the parents who keep their children on the straightened path of education, piety and self-control.
Lord KrishnaTo benefit society at large the benevolent Vaishnava preacher, he who dedicates their life to devotional service, or bhakti-yoga, is kind enough to spray the seeds of devotion all across the land, to every single person willing to accept them. The seed of devotional service can be cultivated within the heart by regularlychanting, “Hare Krishna Hare Krishna, Krishna Krishna, Hare Hare, Hare Rama Hare Rama, Rama Rama, Hare Hare”, and abstaining from the activities most harmful on consciousness: meat eating,gamblingintoxication and illicit sex. This basic formula is only the beginning, with brighter fortunes on the horizon. Through chanting and adherence to the principles of devotional service, the engagement that directly corresponds to the soul’s properties is found.
Is there anything wrong with offering other types of aid? Should we not care for the homeless or feed the hungry? Certainly there is much to be said about helping the downtrodden with material gifts, but as mentioned before, no amount of material gift-giving is ever going to provide any lasting satisfaction. The problems of birth and death are still there even for the wealthiest person. Everything had to be acquired in life after taking birth, so why would anyone want a repeat of that struggle? Even for those born into wealthy families, the struggles of the mind and its influence on activity are present.
Beyond birth and death is the transcendental realm, a place where not a second is wasted in laziness, despair, chaos, tumult, or bad times. The transcendental realm is the home of the Personality of Godhead, the person we are all inclined to worship. Even the atheist has a penchant for worshiping God, but due to his clouded vision he can only see the Lord as material nature, whose most potent force is death. The mental speculator can at best understand God as being an all-pervasive spiritual energy responsible for the motions of all autonomous beings. The yogi can see God in His form as the Supersoul residing within the heart.
Lord KrishnaOnly the Vaishnava, or he who worships the Personality of Godhead, Bhagavan, understands God’s presence found both within and without. This means that the Lord can be worshiped at any time and at any place. Though Krishna is in need of nothing, since He is so attractive, one who has made up their mind to serve Him never runs out of avenues for service. You can chant, dance, sing, read, write, or simply hear about Krishna and you will feel tremendous satisfaction.
“For one who explains the supreme secret to the devotees, devotional service is guaranteed, and at the end he will come back to Me.” (Lord Krishna, Bg. 18.68)
Those who are given the seed of devotional service that has the potential to blossom into a full blown tree receive the greatest gift in life. This also means that those who have carefully sown the seed of devotion within their heart can do the greatest good for their fellow man by distributing the same seeds in the form of the wealth of information found in the Bhagavad-gita, Shrimad Bhagavatam and other sacred texts to as many people as possible. Such preachers are forever dear to Krishna, who appreciates any attempt made to give the individual souls an eternal engagement, a discipline so sublime that its most insignificant fruits are the material amenities previously hankered after.
goldJust imagine unearthing the largest gold mine in the world and distributing its contents to as many people as possible. This should make everyone happy, no? There are two problems. One is that eventually the gold will run out. The other is that no amount of gold will make a person happy. The same concept holds true with money. If you give everyone a million dollars, it doesn’t mean that their problems will suddenly vanish. For starters, if everyone had a million dollars, inflation would naturally kick in, and ordinary commodities would skyrocket in price. But even if we somehow didn’t have inflation, people will react differently with their money. Some will place it in the bank and draw steady interest, while others will start business ventures aimed at increasing the amount of money they have. And there are others who will squander the money away on enjoyment.
Whatever route is chosen, the satisfaction of the mind will still not be there, as the attachment to sense objects will only increase. With distribution of bhakti, however, the mind becomes fully satisfied. Everyone gets the real gold they are due, which they can then make the best use of. And unlike the goldmine, the reservoir of devotional love can never empty. There is no such thing as running out when it comes to distributing the nectar that is the holy name of the Lord. Even if one is not inclined to chant Krishna and Rama, they can recite whatever authorized name they have for God, for the point is to become immersed in an eternal engagement, one that continues well beyond the current lifetime. While no amount of material gift-giving can make others happy, no amount of engagement in bhakti can ever stop the pure devotee from serving their beloved Krishna.
In Closing:
Find a huge pile of gold to distribute,
To all charity you can contribute.
But this will not make anyone satisfied,
Miseries will only be multiplied.
Some squander their money on enjoyment,
Others parlay it to become affluent.
Regardless, attachment to the senses will be there,
Temporary gains and losses, life will seem unfair.
Instead distribute goldmine of bhakti,
Devotion to God, engagement that sets soul free.
Fame and glories of God never do run dry,
On His qualities for pleasure do you rely.
Soul that finds devotion has always to do something,
Glorify Krishna, stories of His pastimes worth telling.
Of conditioned being greatest enemy is lust,
Can be beaten when in Krishna’s name you trust.

நொறுக்குத்தீனி சாப்பிடும் பெண்களுக்கு புற்றுநோய் ஏற்படும்




நொறுக்குத்தீனிக்காக அதிக அளவில் பிஸ்கட்டுகள் மற்றும் கேக்குகளை உட்கொள்ளும் பெண்களுக்கு கருப்பைப் புற்றுநோய் ஏற்பட வாய்ப்பிருப்பதாக புதிய ஆய்வு ஒன்று தெரிவித்துள்ளது.
கடந்த 10 ஆண்டுகளாக நடத்தப்பட்டு வரும் இந்த ஆய்வில் 60,000த்திற்கும் மேற்பட்ட பெண்களை பரிசோதனை செய்து பார்த்ததில் இந்த உண்மை தெரியவந்துள்ளதாக ஆய்வுக்குழுவினர் தெரிவித்துள்ளனர்.
வாரத்திற்கு 3 முறைக்கும் மேல் பிஸ்கட்டுகள் மற்றும் கேக்குகளை உண்பவர்களுக்கு புற்றுநோய்உக்கட்டி ஏற்பட வாய்ப்பு அதிகமிருப்பதாகவும் இந்த ஆய்வில் கண்டு பிடிக்கபட்டுள்ளது.
பிரிட்டனில் மட்டும் ஆண்டொன்றுக்கு சுமார் 6,400 பெண்களுக்கு கர்ப்பப்பை புற்று நோய் ஏற்படுகிறது என்றும் இதில் 1,000 பேர் மரணமடைவதாகவும் அந்த ஆய்வு கூறுகிறது.
ஸ்டாக்ஹோமில் உள்ள கரோலின்ஸ்கா இன்ஸ்டிட்யூட் ஆய்வாளர்கள் பொதுவாக இனிப்புப் பண்டங்களுக்கும் புற்றுநோய் வாய்ப்பிற்கும் தொடர்புள்ளதா என்ற ரீதியிலும் ஆய்வுகளை மேற்கொண்டு வருகின்றனர்.
இந்த ஆய்வில் அதிக சர்க்கரை உள்ள இனிப்புப் பண்டங்கள், குளிர் பானங்கள், ஜாம்கள் ஆகியவற்றை எடுத்துக் கொள்ளும் பெண்களுக்கு புற்று நோய் வாய்ப்பு ஏற்படுவதாகத் தெரியவில்லை என்று கூறும் இந்த ஆய்வு பிஸ்கட்டுகள், பன்கள், இனிப்பு கேக்குகள் ஆகியவற்றை உண்பதால் கேன்சர் ரிஸ்க் 42% அதிகமிருப்பதாகத் தெரிவித்துள்ளனர்.
இந்த ஆய்வு மற்ற ஆய்வுகளின் முடிவுகளுடன் ஒத்துப் போகுமென்றால் கவலையளிக்கும் ஒரு ஆரோக்கியப் பிரச்சனையாகி விடும் என்று தெரிவித்துள்ளனர்.

மெதுவாக உணவு அருந்தினால் சர்க்கரை நோய் வராது: ஆய்வில் தகவல்




உணவை நாம் வேகமாக உண்பதால் சர்க்கரை நோய் ஏற்பட வாய்ப்புள்ளது என்று ஜப்பான் ஆராய்ச்சியாளர்கள் மேற்கொண்ட ஆராய்ச்சியில் தெரியவந்துள்ளது.
லண்டனிலிருந்து வெளிவரும் டெய்லி மெயில் என்ற பத்திரிகை இந்த ஆராய்ச்சி முடிவுகளை வெளியிட்டுள்ளது.
மெதுவாக உணவு உண்பவர்களை விட வேகமாக உணவு உண்பவர்களுக்கு ரத்தத்தில் சர்க்கரை அளவு அதிகமாகி அதுவே சர்க்கரை நோய் ஏற்பட வழிவகுக்கிறது.
10 ஆண்டுகளுக்குப் பின் இது டைப் 2 சர்க்கரை நோயாக மாறும் என்று ஆராய்ச்சி முடிவுகள் தெரிவிக்கின்றன.
இந்த ஆராய்ச்சியில் ஒருவருடைய எடை, பாலினம், வயது, புகைபிடித்தல், மது அருந்துதல் போன்ற காரணிகளை விட வேகமாக உணவு உண்பதினால் மட்டுமே சர்க்கரை நோய் அதிகரிக்க வாய்ப்புள்ளதாக கண்டறியப்பட்டுள்ளது.

குழந்தைகளுக்கு ஏற்படும் நோய்களுக்கான தீர்வுகள்




குழந்தையின் வளர்ச்சிக்கு ஏற்ப உணவு தருவதில் அறியாமை, நோயின் அறிகுறிகள் பற்றிய தெளிவின்மையால் பெரிய பிரச்னைகளை குழந்தைகள் சந்திக்க வேண்டியுள்ளது.
இது போன்ற அபாயங்களைத் தடுக்க குழந்தைகள் விஷயத்தில் சிறப்பு கவனம் செலுத்த வேண்டும். குழந்தைகளுக்கு நுரையீரலில் வைரஸ் தாக்குதலால் சளி, காய்ச்சல் அடிக்கடி ஏற்பட வாய்ப்புள்ளது.
உலக அளவில் 90 சதவீதம் குழந்தைகளை இது போன்ற நோய்கள் தாக்குவதாக உலக சுகாதார நிறுவனம் தெரிவித்துள்ளது. இந்தக் காய்ச்சலுக்கான அறிகுறிகளை ஆரம்பத்தில் கண்டறிந்து சிகிச்சை எடுத்துக் கொள்வதன் மூலம் மூளைக்காய்ச்சல் போன்ற அபாயங்களைத் தவிர்க்க முடியும்.
மருத்துவரின் ஆலோசனைப்படி குழந்தைகளுக்கு குறிப்பிட்ட இடைவெளியில் தடுப்பூசிகள் போட்டுவிட வேண்டும். 6 மாதம் வரை குழந்தைக்கு கட்டாயம் தாய்ப்பால் தர வேண்டும். தாய்ப்பாலில் இருந்து நோய் எதிர்ப்பு சக்தி கிடைப்பதால் குழந்தைகள் ஆரோக்கியமாக வளரமுடியும்.

அது வரை வேறு உணவுகள் தரத் தேவையில்லை. குழந்தை பருவத்தில் அறிகுறி இல்லாமல் காய்ச்சல் ஏற்படும். காய்ச்சல் என்பது நேரடியான நோய் கிடையாது. உடலில் உள்ள வேறு ஒரு பிரச்னையை வெளிப்படுத்தும் அறிகுறியாகும். எனவே காய்ச்சலுக்கு சரியான காரணம் கண்டறிந்து மருந்து அளிக்க வேண்டும்.
குழந்தைகளுக்கு அடிக்கடி மூக்கில் நீர்வடிதல், மூக்கடைப்பு போன்ற தொந்தரவுகள் ஏற்படும். இந்த சமயத்தில் ஆரம்ப அறிகுறியை மருத்துவரிடம் காட்டி மூக்கடைப்பு, சளித் தொல்லைகளுக்கான மருந்துகளை உபயோகிக்கவும்.
அதேபோல் சத்தான உணவுகள் தருவதன் மூலமும் குழந்தைகளை நோய்த் தொற்றில் இருந்து காக்கலாம். குழந்தைகள் தூங்கும் இடம், அவர்கள் பயன்படுத்தும் பொருள் அனைத்தும் சுகாதாரமானதாக இருக்க வேண்டும்.
கிருமி நாசினி பயன்படுத்தி துணியை துவைக்க வேண்டும். குழந்தைகள் பயன்படுத்தும் துணியை வெயிலில் உலர்த்துவதன் மூலம் நோய்த்தொற்று ஏற்படுவதை தவிர்க்க முடியும். குழந்தைகளுக்கு உணவு கொடுப்பதிலும் கவனம் தேவை. தாய்ப்பால் குறைவாக இருந்தால் புட்டிப் பால் கொடுக்கப்படுகிறது.
இது போன்ற சமயத்தில் கவனமின்மையால் நோய்த் தொற்று பரவுகிறது. மேலும் குழந்தைகளுக்கு சாப்பிட கொடுக்கும் காய்கறிகள், கீரை வகைகளை கல் உப்பு சேர்த்த தண்ணீரில் கழுவி சமைக்க வேண்டும்.
தண்ணீரின் வழியாக அதிகளவில் நோய்கள் பரவுவதால் காய்ச்சி வடிகட்டிய நீரை மட்டுமே குழந்தைகளுக்குக் கொடுக்க வேண்டும். இவற்றில் கவனம் செலுத்தாமல் விடும் போது குழந்தைக்கு வயிற்றுப் போக்கு ஏற்படுகிறது. மேலும் சுகாதாரமற்ற உணவுகள், பழச்சாறுகள் மூலம் தொற்று நோய்கள் ஏற்பட வாய்ப்புள்ளது.
குழந்தை வழக்கத்துக்கு மாறாக அதிக முறை தண்ணீர் போல மலம் கழித்தால் உடனடியாக மருத்துவரின் ஆலோசனை பெற வேண்டும். வயிற்றுப் போக்கின் போது குழந்தையின் உடல் நீர்ச்சத்தை இழக்க நேரிடும். குழந்தைகளுக்கு அடிக்கடி வரும் பிரச்னைகளுக்கு மருத்துவரின் ஆலோசனைப்படி மருந்துகள் தயாராக வைத்திருப்பது நல்லது.
குறைப்பிரசவம் மற்றும் எடை குறைவாகப் பிறந்த குழந்தைகளுக்கு ரத்தத்தில் கிருமித் தொற்று ஏற்பட வாய்ப்புள்ளது. இதற்கு தற்போது தடுப்பூசி உள்ளதால் மருத்துவரின் ஆலோசனைப்படி போட்டுக் கொள்ளலாம்.
சாதாரண சளித் தொல்லை ஏற்பட்ட குழந்தைக்கு மூன்று நாட்களில் காது வலி வர வாய்ப்புள்ளது. அப்போது எந்த அறிகுறியும் இன்றி குழந்தை அழுதபடியே இருக்கும்.
குழந்தை அழும் போது அதன் காது, வயிறு என உடலின் பாகங்களைத் தொடும் போது குழந்தை காட்டும் எதிர்ப்பை வைத்து அதன் வலியைக் கண்டறிய முடியும். குழந்தைக்கு 6 மாதங்கள் முடிந்த பின்னர் வீட்டு உணவுகளைப் பழக்க வேண்டும்.
சரியான சத்தான உணவு முறை மற்றும் சுகாதாரத்தை கடைபிடித்தால் குழந்தைகளுக்கு நோய்த் தொற்று ஏற்படாது. சின்ன பிரச்னை வந்தாலும் குழந்தைகள் மருத்துவரிடம் ஆலோசனை பெற்று மருந்து தரலாம்.
மருந்துக் கடைகளில் மருந்து வாங்கித் தருவது மற்றும் மற்ற குழந்தைகளுக்கு கொடுக்கும் மருந்தைப் பயன்படுத்துவதும் தவறு. ஒவ்வொரு குழந்தையும் தனித்தன்மை மிக்கது. அந்தக் குழந்தையை ஆரோக்கியமாக வளர்க்க வேண்டியது தாயின் பொறுப்பு.
