Module 4

Ekonomiese oorlewing

DIE EKONOMIESE DILEMMA

Seker die grootste ekonomiese probleem waarmee die meeste mense daagliks worstel, is die feit dat hulle begeertes en behoeftes baie groter is as hul bankbalans. Daarom word mense gedwing om te kies watter behoeftes en begeertes hulle gaan bevredig. Daar moet ook besluit word hoe om die bronne wat wel beskikbaar is, ten beste aan te wend om hierdie keuses te bevredig.

OORLEWING

Opdrag

Kom ons doen ‘n oefening om te probeer vasstel wat die minimum bronne is wat ‘n mens nodig het om te oorleef.

Jy was aan boord van ‘n klein vliegtuigie wat op ‘n eiland in die Stille Oseaan neergestort en uitgebrand het. Jy is die enigste oorlewende en het net die volgende artikels by jou . . . .

1 dosie vuurhoutjies

die klere aan jou lyf

‘n kaart van die eiland en omliggende see

Terwyl jy die eiland verken, ontdek jy die volgende:

daar is ‘n rivier met vars water;

die dae is redelik warm en die nagte koud;

daar is ‘n beboste gedeelte met vrugte soos piesangs, papajas en kokosneute;

jy gewaar leeuspore en slange in die droër dele;

die vis in die baai is volop.

Beplan jou eerste week (7 dae) op die eiland en skryf ‘n kort verslag oor elke dag.

[LU 1.2]

Groepwerk

Veronderstel jy is een van ses oorlewendes op die eiland. Beplan hoe julle gaan oorleef. Maak seker dat julle die volgende aspekte aanraak as deel van jul beplanning:

Watter onmiddellike behoeftes is die belangrikste en hoe sal julle te werk gaan om daarin te voorsien?

Watter bronne is op die eiland beskikbaar? Is hierdie bronne beperk of in oorvloed? Waarvoor kan dit aangewend word?

BESKIKBAARHEID VAN BRONNE

Die ideaal is dat bronne onbeperk moet wees, maar wanneer beskik ‘n gemeenskap werklik oor alle bronne wat hulle benodig? Bereik hulle ooit daardie versadigingspunt? Wat bepaal en beïnvloed die behoeftes en begeertes van ‘n gemeenskap? Bespreek in groepe.

Gemeenskappe het oorhoofse behoeftes en begeertes. Voorbeelde van gemeenskapsbehoeftes (probeer die lys aanvul) is:

mediese dienste

sport en ontspanning

voedsel en water

beskerming

opvoeding

vermaak

Hierdie behoeftes en begeertes word in ‘n groot mate ondersteun deur openbare goedere en dienste. Voorbeelde hiervan (vul dit aan):

hospitale / klinieke

sportvelde

sakesentrums

polisie

skole

paaie

Assessering

LU 1

DIE EKONOMIESE KRINGLOOP

Die leerder is in staat om kennis en begrip van die ekonomiese kringloop binne die konteks van “die ekonomiese probleem” te toon.

Dit is duidelik wanneer die leerder die volgende doen:

identifiseer en beskryf die staat se rol in die gebruik van hulpbronne en dienste

Memorandum

Klem op oorlewing: kos en veiligheid.

Groepwerk

Groepe van ses kan goed werk. Groepe moet positiewe sowel as negatiewe (gevare) aspekte van eiland in gedagte hou en ‘n plan van aksie saamstel waarvolgens hulle vir ‘n tydperk sal kan oorleef. Kyk veral watter groepe ook aandag aan reddingspogings gee.

C. Het ons ooit genoeg van alles? Kan lys uitgebrei word?

do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
