I have tried and tested a blood pressure wrist watch and found what you have found “..นาฬิกาวัดความดันไม่แม่นยำ ไม่น่าเชื่อถือ..”. I looked up the principle of pulse oximetry (used in the wrist watch) and found (eg. https://www.sciencedirect.com/science/article/pii/S095461111300053X ) that there are a number of factors affecting ‘accuracy’ (compared to traditional devices): for examples: response to light at specific wavelengths (the 2 light pulsing leds under the watch), algorithm used in computing the values, and the ‘condition of blood and blood vessel’.

Pulse oximetry has been found useful (‘accurate’) in use on children in a study. (Does this mean their blood and blood vessels give better response than our aged blood vessels?). The algorithms are very much statistical (average based x samples of responses in about 10 seconds), and being studied intensively - so as new and improved technologies are going, we can expect ‘more consistent’ measurements. (Updates and upgrades of pulse oximeters can be done ‘on air’ like phones and tablets, make a lot of complaints and wait for new firmware versions ;-).

I see potential as cheap and useful health/patient monitoring device for use at home and in hospital. With a little more processor memory, and more weather-proof design, healthcare and services can be much improved and costs lower for both patients, health providers and taxpayers. (Many good research and development for universities, businesses and investors can piggy back on FOSS materials - look up GitHub to get started.)

I thank you for continuing to serve society even under very difficult and restrictive conditions.

I hear that most people only use 10% of their brain power, you are using more than that and for very honorable causes. You have my respect.

I have just been reading and digesting ‘Earth, Inc’ (suite of articles in the Time magazine April 28/ May 2, 2022 issue) and now https://www.sdgmove.com/2022/04/28/the-time-impact-ranking-sdgs-thailand-top-cu-cmu/ . I think many have come on the right path (to the right future).

The day will come that graduates with sustainable Earth attitudes are in positions to steer businesses, public administration, education and development of Earth.

Somehow, I relate that to practice-to-research and research-to-practice in cycle.

And I can relate Kolb’s ELC back to ขันธ์ 5 (concrete) รูป; (abstract) เวทนา สัญญา สังขาร และวิญญาณ. ขันธ์ 5 can be viewed as steps in a learning process. Here, ‘Learning’ is a cycle of ‘concrete experience’ (รูป) getting ‘perceived’ ( เวทนา) , recognized (สัญญา), synthesized (สังขาร) and ‘learned’ (วิญญาณ); then from applications of what have been learned ‘concrete experience’ arises and …

It is unfortunate that Thai meanings for these Palī terms obscure the greater understanding of the Buddha teaching and prevent its applications in Thailand.

And what many state universities do not realize is that not only their university (organization) is going down, their students and alumni are also going down with them. Negative images can remain detrimental to their life for some time.

Change or die - a long death.

I had posted some questions about “Food for Life on Us; How Much Food is Enough for Life on Us?; and Microbiotic food” some years back (in hope that they would lead to some food research activities -in Thailand- or else where) in “Food or Rubbish 3” [ https://www.gotoknow.org/posts/592300 ].

In short, I asked if we should feed our gut bacteria rather just ourselves. It seems that the answers (from various research results so far) are “yes”. But we have not anymore wiser about “what food is good for our gut bacteria”, apart from ‘suggested’ eating roughage/fiber-rich vegetables. I think we would guess that our ‘gut biome’ have ‘similar nutrient need’ to us and suffer from ‘similar anti-nutrients’ (toxin, poison, ‘killer micro-organism’/antibiotic,…) like us.

The devil is of course in the details.

Thank you GD. Your answer is absolutely correct.

Would you like to share ‘how’ you work this out?

I am sure as teachers we would be interested in the ‘process’ (logical steps before arriving at the solution or conclusion) more than just a correct answer.

We can quote a well-known proverb about teaching ‘how to fish’ because a gift is merely a temporary help. The children should learn not just remember answers.

Thank you for the link to the book. I read a few chapters so far.

Chapter 1 introduces บางกะเจ้า ปอดของกรุงเทพ, and chapter 2 tells ที่มา ชื่อบางกะเจ้า …แต่สันนิษฐานว่ํา คำว่ํา ‘กะเจ้า’ ม่าจากคำว่ํา ‘นกกระยาง’ ในภาษาเขมร… This struck me as odd, so I looked up the Royal Society Thai Dictionary (2542 and 2554 editions) and did not find ‘กะเจ้า’ nor ‘กะเจ่า’ in the dictionaries. But

From Royal Institute Dictionary (2542 Th-Th)กระเจ้า ๑  (ถิ่น) น. นกยาง เช่น กระจาบกระเจ้าจับ ซ้องศัพทอึงอล.  ๒ (ถิ่น-พายัพ, ปักษ์ใต้) น. ต้นกระเชา. ( ดู กระเชา)กระเจ่า (ถิ่น) น. นกยาง เช่น กระจาบกระเจ้าจับ ซ้องศัพทอึงอล.

Google’s Translate (Thai -> Khmer) says:กระยาง = សត្វក្រៀល สัต-กึ-เรียล / สัต เกรฺียล in Khmer (សត្វ = สัตว์) กระเจ้า = ព្រះ เพรีย (= พระเจ้า in Thai)

So there is a (trivial) inconsistency possibly in the dictionary as it does not include this official locality (‘place name’). The example ‘กระจาบกระเจ้าจับ ซ้องศัพทอึงอล’ is given without reference to its origin. This example is propagated to many Thai dictionary websites. Perhaps the Royal Society should update the Thai dictionary and provide references so we have a more comprehensive dictionary.

[We can preserve our culture better if we do not let it become irrelevant.]

Sigh! Ground-in culture of corruption/greed in human society is very hard to correct. Perhaps adding more steps to selection/appointment process to lessen importance of any single step and to encourage multi-skill development among candidates may help. Then if we can’t handle simple process, what chance do we have to handle complex process?

I recall ‘a teaching’ from a fisherman many decades ago about fighting beach erosion in a coastal town by building rock barriers way out into the sea. He said the direct oppositional rock water-breaks were no match for the waves and swells, only served to deposit sand in odd places, a disaster for swimmers, fishermen and small boats. It would have been better to divert the the power of the waves in strategic sections of the beach, creating safer areas for swimming, fishing and boating.

I summed up the teaching as ‘channeling can work better than blocking’. And years later after using this teaching, I added ‘and cost much less’ (because we can use the coming force to do some work for us - instead of making another force to counter it).

I suppose this “…ข้อสาม ดื่มไวน์แดงบ้างเล็กน้อย (ได้ flavonoids) …” is not included in [Bhuddhists’] ‘magga 8’ because it is against the 5th sīla. And that ‘a little’ to one may be ‘a lot’ to another and vice versa.

But I think the sīla asks us to ‘learn to refrain from ..’ (not prohibit from ..) as the Palī goes ‘..manīsikkha..’ (a valuable lesson to learn).

I think not only the President of the Russia Federation is acting under ‘worldly attachments’, many leaders (of countries around the world) are also chained up by attachments too. Some have brands like ‘for the people’, ‘by the people’, ‘for glory of the past’, ‘towards the “better” future’, ‘economy’, ‘prosperity’, {country-name}/{race-name}/{religion-name}/{?-name},…

Look at examples of these attachments: in histories, kings legitimized their sovereignty over the conquered countries (and people) by claiming strong bond to any one or more of the above attachments; in the present time when a country runs out of money, money is created (printed) by making a law to make it legitimate to create money (out of thin air); and to invade another country, a reason and a collective decision is created (again from morsels of anything).

Thank you for sharing this useful and life-saving speech and especially to นพ. สันต์ ใจยอดศิลป์.

I like the 7 tools: Attention, Breathing, Relaxation, Body scan, Observation, Concentration, Alertness. They are very much like ‘สมาธิ’ or ‘ปฎิบัติธรรม’ in Buddhism but in layman terms. I also relate Body scan and Observation tools to practicing physical sensory perception - that is ‘awareness’ of the environment/surrounding condition (so that we ‘live in the present’ not ‘ideal’ or imaginary world (eg. metaverse, VR,..).

I think issues like ‘information systems (including accounting, assets & inventory, personnel, patient registry and knowledge database subsystems) should been included in the consideration –so that ‘delegation of services’ is not leading to ‘isolation of services’ and increased risks and/or costs for the public they are supposed to serve.

Perhaps, work ethics training should be available to all public servants. Issues like honesty (or truthfulness), courtesy (or moral observance) and parsimony (most effective, least waste, within the condition) should be included.

And another ‘life ethic’ that ‘responsibility goes up, and authority goes down’ (meaning ‘the higher ranking personnel must take responsibility for all under her/his control; and s/he must delegate her/his authority to operatives under her/his control’).

Many cultures have these values built-in. Multi-cultures (such as Thailand) need common set of values and promotion. Equal opportunity is a hard value to build.

May I put an emphasis on this “..เมื่อได้รับการยอมรับ ในรูปแบบใดก็ตาม ร่างกายมนุษย์จะหลั่งฮอร์โมนแห่งความสุข (dopamine และ serotonin) ออกมา และระดับฮอร์โมนแห่งความเครียด (cortisol) ลดลง นอกจากเพิ่มความสุขแล้ว การได้รับการยอมรับยังช่วยเพิ่มพลังสมองด้วย เพราะระดับของ โดปามีน และซีโรโทนิน ช่วยการเชื่อมต่อใยประสาท เคล็ดลับคือ เราสามารถให้การยอมรับ (หรือให้รางวัล) ตัวเราเองได้ ว่าได้ทำสำเร็จในสิ่งที่ยิ่งใหญ่ (โดยไม่ต้องเปรียบเทียบกับใคร) ..”?

It is a secret of being successful. Once we convince ourselves that we succeed and we are happy with our success. ;-)

It puzzles me that these “…ากผู้บริหารท้องถิ่นใช้เงินของท้องถิ่นตั้งบริษัทดีก็ดีไป แต่หากคิดไม่ถี่ถ้วนนำเงินไปลงทุนทำบริษัทแล้วไม่ประสบความสำเร็จจะเกิดวิกฤตอย่างรุนแรง เหมือนดังเช่น ข่าว (2558) เทศบาล 5 แห่งในจังหวัดขอนแก่น ร่วมมือกันตั้งบริษัทจำกัดจัดระบบขนส่งมวลชน โครงการก่อสร้างรถไฟฟ้ารางเบา (the construction of a light rail system in the city) หรือ โครงการระบบขนส่งมวลชนแบบอัจฉริยะ Khonkaen Smart Mobility หรือ ระบบขนส่งมวลชนโดยใช้รถโดยสารด่วนพิเศษ (Bus Rapid Transit หรือ BRT) เป็นต้น …” failed while still running (according to ‘news i found on the Net’). Could you please enlighten me?

I read and got stuck on “ ..โมเดล เป็นผลของการลดทอนส่วนที่ไม่สำคัญออกไป เหลือเฉพาะส่วนที่จำเป็นเท่านั้น เพื่อให้เข้าใจ หรือทำสิ่งนั้นๆ ได้โดยง่าย..” because I have experienced difficulties in assessing what relevant and what important. on one hand we have system theories on “principal components analysis” (reduction to ‘main’ components). On another hand, we have system catalyst theories for “mechanisms of systems” (how the system works). There are numerous examples that – often very small or overlooked-and-discarded components are “essential” for operation of the system or the process.

Autonomy usually comes with self-sufficiency. Funding issues involve some forms of control. So financial/revenue support is very important even as a not-for profit.

The window for view this planet alignment is closing as the moon’s position is fast shifting out of alignment. We will see the other 4 planets for a few more days. But to them with the Moon again, we will have to wait few thousands years.

Many people who looked at this planet alignment may also see ‘moving stars’ crossing the line of planets - they are some the many ‘artificial satellites’ in orbits. Not ‘UFO’. Sorry.

I am glad you found it interesting and exciting ;-).

My thought is that ‘space research/industry’ may only serves economic and scientific interests – not so much for human travel among stars. Extra-terrestrial beings would find the same physical laws on the speed of light and so find the same problems in visiting Earth from other stars.

But there is no limit to imagination and human endeavour. We just have to make best use of our abilities to match the laws of Nature.

I can’t help but thinking about ‘whole and parts’ and as far as I know this area is in ‘the too-hard-basket’. Take for example our body and various organs that work together (not necessary at the same ‘site’, on the same ‘objective’ and in the same ‘time’). All contribute in their own different capacity to support survival, functions and growth or sharing of benefits –to each organ, its need. So that the brain is ‘credited’ with glucose its need; the colon is credited to its need; the hands, the legs, the ears, the eyes, the mouth, the teeth, … all contributors in their own capacity, are credited to meet their need. (Excess get stored as ‘fat’? which is a ‘burden’ that all organs have to bear!) Another example is the nutrient distribution of a tree. Some roots and some leaves are collectors of nutrients, but stem, veins, bark, branches and so on all get nutrients they need though they do not collect any nutrients (but they are involved in the process of nutrient conversion).

It is easy to say ‘each to its need’ but we human are confused by need and want.

May I add a link to an article on ‘Thailand in the 1990s’ ?


It tells about political scenes (–corruption is not covered–) that impact government policies and many government services have not recovered (30 years on).
