Doctrine of Signatures

Doctrine of Signatures
By examining the physical characteristics of plants we can read how nature intended them to be used. This is not true. 

Dr Abe V Rotor

 
 Staghorn fern; colony of foliose lichen

This is a belief called Doctrine of Signatures, which was popular during the Middle Ages. Liverworts (Riccia and Marchantia) which resemble the shape of liver are effective for liver diseases. The shapes of eggplant and avocado suggest fertility and aphrodisiac value. Apple and mango resemble the heart and are therefore good when it comes to matters of love. Kidney beans are good for the kidney, but the truth is that it has high uric acid content. The garlic plant has a hollow stem so that it would be of benefit in afflictions of the windpipe, hence used in all types of respiratory disorders such as cough, colds, catarrh, asthma and bronchial problems.

Physical appearance has nothing to do with the curative powers of plants, or animals for that matter. It is true that garlic is an effective respiratory cure, but it is its active ingredients that are responsible for it. ~

Legacy of the late NFA Administrator Jesus T Tanchanco

       Legacy of the late NFA Administrator Jesus T Tanchanco

(Administrator, National Grains Authority and National Food Authority, 1971-1986).

Dr and Mrs Abe V Rotor exchange pleasantries with former NFA administrator Jesus T Tanchanco (right) during the last homecoming of former NGA-NFA employees in 2012.  It was the last meeting of our group with this great man.    

1. Live in the present. Live today. 

2. Forget the mistakes of yesterday. Yesterday has gone forever. 

3. Stop criticizing yourself and stop criticizing others. 

4. Yearn for self-improvement. 

5. Hold on to your self-respect by appraising yourself honestly. 
  
6. Learn to listen to others. It helps remove bias from your opinion. 

7. If you have a goal, reach for it. 

8. If you make a mistake, try again. 

9. Don't be timid in conversation. 

10. Exercise your imagination creatively to achieve success. 
  
11. Do one thing at a time. Shoot for one goal at a time.

12. Believe in the Providence not for luck but blessings.

*From my old files I found this article ideal for framing, so that it can serve as a daily personal reminder. Spontaneously I thought of my boss for fifteen long years, the admirable and respectable Jesus T Tanchanco, former administrator of the National Food Authority under the regime of President Ferdinand E Marcos. During his time the Philippines became not only self-sufficient in rice and other major agricultural commodities, but a net exporter as well. The Philippines attained the status as exporter of rice in Tanchanco's time like Thailand and Vietnam today. I realize that the success of a leader - a government official - depends largely on personality which is the embodiment of the qualities of that person.

Smartphone Pandemic - Digital Addiction

 Smartphone Pandemic  

"People who spend countless hours on their smartphones or tablet computers could be addicted without even knowing it."
 
Soon there will be as many cellphones as the world's population, increasing  at an alarming proportion as a pandemic.   
----------------
Smartphone technology has significant applications in our lives today.  Its evolution into the fifth generation cellular network expansion, faces a global challenge to play a greater role in education, media, medicine, commerce and industry, in fact all sectors of society.

"The Joneses." The smarter, the most dynamic, the signature, the most expensive.  Cellphone as status symbol. 

 Cellphone, cellphone everywhere and not a time to blink. 
 
Three coins in a fountain formerly a song, now a watering 
hole of cellphone addicts.

                         Always calling - in their casual shorts. Cellphones are cool.  

Selfie - new vocabulary, most common command, 
And say, "I was there with the Queen, see?"

Doctors warn nothing smart about cellphone addiction amid calls to label it a disorder

Do you experience anxiety when your smartphone or tablet computer is nearly out of power or out of WiFi range? If so, you could be suffering digital addiction. Photo: IC 

 It is an epidemic sweeping the nation that affects men and women, adults and children, migrant and white-collar workers. At any given time of the day you can see addicts reaching into their pockets to get a hit, ignoring people around them as they slip into a zombie-like state of swiping and texting. As the world's largest smartphone market, China is experiencing digital addiction on an epidemic scale.

A team of psychiatrists in Singapore recently called on medical authorities to recognize digital addiction, characterized by excessive use of smartphones and the Internet, as a mental disorder. Their warning follows the release of a 2013 report by media monitoring firm Nielsen that found the Asia-Pacific region has some of the world's highest smartphone penetration rates, which are blamed for causing physical and mental harm to users' health. In China, there are more than 24 million digital addicts whose average age is progressively falling, the survey found.  

Taking over lives

Digital addiction has become a growing problem in China, where there are an estimated 300 centers to treat the problem, according to a report in February by China Central Television. 

Deng Weiwei, 21, describes herself and many of her friends as "heavily addicted" to their smartphones. "I will unconditionally accept it if one day smartphone addiction is classified as a mental disorder," said Deng, who said she is transfixed on her smartphone when she is "not working or sleeping." "Sometimes I find myself suffering great anxiety when my smartphone is out of battery or I can't access WiFi. It's like an obsessive-compulsive disorder that controls me."

Tao Ran, director of the addiction center at the People's Liberation Army General Hospital in Beijing, said people who spend countless hours on their smartphones or tablet computers could be addicted without even knowing it. 

"All Internet addicts are hooked on their smartphones. More accurately, they are digital gadget addicts," said Tao, who runs a digital addiction boot camp based in Daxing district that currently has 80 addicts. 

Tao, who previously specialized in treating narcotics abusers, has dealt with digital addicts as young as 9 and as old as 56, but most people who seek help are aged in their teens or 20s.

"The concept of digital addiction has been around for about 20 years. My first patients were three boys who came to me in 2003. They were addicted to online gaming and refused to go to school," recalled Tao. "Now, nearly all children have smartphones. If they are banned from computers they can still play online games with their smartphone." 

Violence is one reason why few parents dare confiscate their children's smartphones or restrict their Internet access, said Tao, who estimates around three-fifths of children attack parents who enforce such measures.
China, the world's largest smartphone market, has an estimated 24 million digital addicts, according to a 2013 study. Psychiatrists are divided over whether gadget addiction should be diagnosed and treated as a mental disorder. Photo: CFP

Diagnosis of addiction

Tao has treated 164 patients using nuclear magnetic resonance, which allows observation of specific quantum mechanical magnetic properties of the atomic nucleus. Results show that the oxygen metabolism of addicts' frontal lobes, which play a role in behavior and personality, and parietal lobes, which process sensory information such as touch, temperature and pain, are weaker than people who aren't addicted to digital gadgets. 

The part of the brain responsible for experiencing pleasure among addicts is 20 percent more active than non-addicts, said Tao.

Addictive behavior can be physical and psychological. Physical dependence involves addiction to substances, such as alcohol or other drugs, while psychological dependence involves addictive behavior, such as with digital gadgets, gambling, sex and so on. 

"The pathogenesis of gambling and physical dependence of substances, such as alcohol, tobacco and other drugs, are the same," said Yang Kebing, director of the alcohol dependence department at Huilongguan Hospital, Changping district. 

"If the neural circuit is too frequently stimulated, it can manifest into a mental disorder. If stimulation stops, a series of physical and mental symptoms can appear."

However, Yang said it was too early to classify digital addiction as a mental disorder based on current pathological data. "Since the trend of smartphone addiction is increasing, I don't exclude the possibility of it being labeled a disorder [in future]," added Yang.

Seeing the harm caused

Aside from mental woes, digital addiction can also wreak physical harm to smartphone junkies. The Xinhua News Agency reported on June 10 that a woman in Wuhan, Hubei Province, suffered floaters, or small mass particles inside the eye that affect the field of vision, triggered by excessive smartphone use. A doctor who treated the woman said the disease was not too serious, advising rest and avoidance of digital gadgets the simple remedy. 

A more serious case occurred earlier this year when a woman in Zhejiang Province suffered a detached retina after spending two to three hours daily looking at her smartphone in the dark. The woman, surnamed Liu, saw an ophthalmologist after she noticed vision in one of her eyes had become cloudy and distorted, Xinhua reported on February 23. 

Zhao Bingkun, the ophthalmologist who treated Liu, said in the report that long hours staring at a bright screen in the dark can cause the ciliary muscle, which changes the shape of the lens within the eye, to over-contract when viewing objects at varying distances.

The report said ophthalmologists are seeing a growing number of patients suffering from the condition caused by users staring at screens of computers and smartphones for too long without a break.

Children at risk

Flurry, a mobile analytics company headquartered in San Francisco, estimated that the number of smartphone addicts worldwide increased by 123 percent in the year leading up to April 2014 to hit 176 million. 

Flurry's study was based on feedback from more than half a million apps used by 1.3 billion smartphone users globally. Addicts were identified as anyone launching apps more than 60 times per day.

Another report of Flurry showed China has surpassed the US to become the largest market for smartphones. From January 2012 to January 2013, the smartphone market in China grew 209 percent. During this time, 150 million new phones or tablet computers were purchased in China, compared to 55 million in the US.

A survey by Tao of 11 residential communities in Beijing in April found that most parents who have toddlers use smartphones or tablet computers as "electric nannies" to amuse their children. 

Even when eating or bathing, many parents surveyed by Tao admitting using digital gadgets to keep their children settled.

"Some young parents themselves are digital addicts, and they are just passing on their addiction to the next generation through gadgets some consider useful to early education," said Tao. 

"Parents only know that digital gadgets settle their children down. Little do they know they are actually grooming them as digital addicts."

Harm or hype?

Despite the fears and dangers surrounding digital addiction, some psychiatrists insist there is no need to panic about current levels of smartphone use among most people. Yang described the condition as "just a bad habit rather than a disease." 

Chen Fuxiang, marketing director of domestic smartphone maker Xiaomi, said much of the hype surrounding digital addiction would pass with time, noting popular devices and pastimes among youths are often chastised by society. 

"When I was a student, there were no computers, and our society worried about youngsters getting carried away by their addiction to kung fu novels. After computers came along, society worried about Internet addiction. Now we have smartphones, and naturally there is worry about smartphone addiction," said Chen, conceding that more can be done by smartphone makers by offering users advice and guidelines related to safe use of their devices. 

"In future, we will still have other addictions to worry about." ~

What's wrong with these images? SEE ANSWERS

                         What's wrong with these images? *

"You and I may lie, but the camera doesn't lie," no longer holds true, unless you fully use your God-given faculties. - avr

Dr Abe V Rotor

The position of the violinist is reverse.  No one
can possibly play the violin with the right hand 
on the keyboard and the left with the bow. 
This is a mirror image. (Photo from the Internet)

Definitely, it's not a snow-capped mountain.  
Otherwise the snow is on the summit and not on 
the slope.  The view is a huge cloud formation. 
 I took this photo one cloudy day in San Vicente, 
Ilocos Sur just beside the old church.  You can 
trace in the distance the Cordillera range, the 
eastern boundary of the two Ilocos provinces
 - Ilocos Norte and Sur.
 
This is a true photograph, unedited. There's no trick involved.  
The moth displays two false large eyes, one on each of its 
forewings, as bluff but effective defense, against would-be 
predators. The background is a mural scene of nature that 
could have attracted the creature one late afternoon.  In 
general, moths and skippers are crepuscular and 
nocturnal, unlike butterflies which are diurnal. ~


Freedom of Expression in Arts

 Freedom of Expression in Arts
Dr Abe V Rotor

A Field of Lilies
The painting looks elaborate. I used cotton string (No. 20), soaked in latex paint to create these lily-like figures. The string is made into a series of loops, then pulled downward. The technique is not new, it is used in art lessons in school, only that I modified the technique by first painting the background.  The streaks were formed by narrow paint brush and palette knife. A bit of pointillism was applied to create a natural effect with weeds growing all over the field. 
                             
Rock Pool 
It looks like an aerial view of a meandering river meeting at certain points to make it appear like a rock pool, typical in estuaries in actual scenes. I used palette knife, semi-hardened latex paint for the relief effect, and surplus plywood in lieu of canvas. Much of the work was done with fingers, and patchwork with stones and pieces of wood. 
  
Lahar Rocks
Actual lahar rocks are mounted on solid wood with transparent glue, over a scene earlier painted and allowed to dry. In reality lahar rocks do not float, even if they are porous. I simply took advantage of the contrast provided by a blue background that appears like moving water. Lahar flows like mud and becomes silt, unless it solidifies in the process of volcanic eruption.

A Pair of Parakeets in Camouflage
Watercolor effect is a result of thin mixture allowing colors to settle down slowly, In the process secondary and tertiary colors spontaneously form. Gradual fusing of colors creates hues that have a soothing effect to the viewer. There's one precaution though, too much smudging may ruin your painting.

Dicot Leaf Venation
Study the venation of a dicot leaf, and you will find it more complex than the mythological labyrinth of the Minotaur. It is because there are no clear passages, no entrances and exits. The network is contiguous and irregular. Now, how can you make a maze in a painting? Sandwich thick pre-mixed latex paint between two plywood panels, compress, then separate them evenly. Now you have two surfaces bearing the relief of leaf venation. Dry with heat gun to fix the patterns. Proceed in painting the two surfaces in the usual way. Be sure you heighten the network pattern as shown in this painting.

                        
                                      Banaoang Pass, Santa, Ilocos Sur
 (Minus the old Quirino Bridge) 
It's an old concrete wall at home, the outline of hollow blocks visible after a layer or two of latex paint. It was in subsequent paintings that I was able to hide the unsightly impressions. How? I used a pair of metal palette, the one used in applying masilla (primary coat). As I continued I found it exciting to use paint brush and fingers to create the relief effect, with the view of my favorite landscape always in my mind. This work remains unfinished to this day. I resolve to finish it after the rainy season. I hope.

  
Allegory Cave
It's a cave of Plato, the Greek philosopher. Can you tell the story? The cave is a symbolic representation of how human beings live in two worlds, contrasting reality on one hand, and our interpretation of it, on the other. These two ideas reflect the two worlds in the story: the world inside the cave, and the world outside. The story goes further. In the cave you only see shadows, moving shadows from the outside world, and not having a clear idea of what life is outside the confines of the cave. One day, one of the "prisoners" found a way out and saw how beautiful the world is, and how happy and free people are. It is what we call the phenomenon of enlightenment. But the "enlightened" fellow never went back to tell his companions to share his experience, and ultimately to help in leading them out. This is where the philosophy of the great Plato comes in. What is humanity? What is education? Brotherhood? Compassion? Social responsibility? Mutual Understanding? Peace? I made the façade of the cave colorful and inviting. Would a newcomer dare to enter, but for what purpose?, Art leaves us dumbfounded, innocently ignorant, and quite often, amoral and indifferent. Plato built the first university - the Lyceum - which stood as the epitome of learning for centuries and many generations, until it fell into destruction by no other but the hands of man.
 
                             Shipwreck                                       
Not yet. But look at the painting again, longer this time. It is like waiting for Salvador Dali's melting clock hanging at the edge of a table soon to fall off. Art makes you anticipate the consequence. And the more tragic it possibly is, the more you are glued to your seat. Imagine yourself in the precarious situation. The more the artist in you rises to the challenge to capture the catastrophe. Study movement in the painting - the direction and force of water and wind, the anticipated inevitable crash against rocks and old lighthouse itself, Here you ask, of what good is this lighthouse?

Hidden Pond of Monet
It's almost a copy of a Claude Monet's masterpiece, save the isolation of the scene beneath thick hanging vegetation. Otherwise, the landscape could have been bathed in glorious sunlight. It is in the last years of the artist that, in spite of failing eyesight, he could still use his vision, for ultraviolet light waves. For which he was considered famous for his ultraviolet and ultra blue paintings, as he was already known for his vibrant and peaceful paintings in his younger years. How far did I capture the Monet's Effect in this painting? It's a far cry.

                                                                     Milky Way Galaxy
It's milky in color in the first place, dissolving multitudes of stars. It's very, very far, yet it is our galaxy. Our sun, and all its planets, is a member. It is the star nearest us which gives energy and life that makes our planet the only known place in the universe where life exists. Painting this subject is imagining and applying the so little information we know of about the vast universe. If there is a theme to express in painting the Milky Way galaxy, as well as other galaxies numbering thousands if not millions, it is one that would give you as an artist limitless space you can explore with imagination and creativity - which may be reason to be excused from the strict rules of dimension, perspective, colors, form, and other elements of art. ~

Weirdest photographs I Took. (My Best Photographs Series 12)

                   Weirdest photographs I Took

Dr Abe V Rotor

Driftwood comes hauntingly alive resembling the head of a 
wild beast complete with snout, jaw, nostril, and an almost 
real eye. On display at the Living with Nature  museum.  
San Vicente, Ilocos Sur  

Shelf mushroom emerges from the trunk of a dead tree in 
concentric pattern, with the outer ring resembling the halo 
of the sun, and other heavenly bodies.

Glowing caterpillars crowd a branch of ilang-ilang stripping the 
leaves to the midribs overnight. The phenomenon involved 
is known as phosphorescence,  Here high concentration of
 phosphorus glows in the dark, a common observation in 
nature particularly among coral reef  organisms.
