Lewensprosesse: ‘n gesonde lewe

Module 8

Gesinsbeplanning en geslagsiektes

Geslagsiektes:

  • Aangesien seks die nabye kontak tussen twee persone behels, word aansteeklike siektes maklik oorgedra. GESLAGSIEKTES word met SEKSUELE KONTAK oorgedra.
Siekte Simptome Infeksie agent
VIGS
  • Immuunstelsel aangeval
  • Persoon kry siektes soos kanker, longontsteking en swaminfeksies en het geen verweer daarteen
HI-virus
GONOR-REE
  • Babas word blind gebore
  • Branderige urinering
  • Pynlike gewrigte
Bakteriese infeksie
SIFILIS
  • Seertjies op geslagsdele
  • Veluitslag
  • Bakterieë kan brein aanval en blindheid en waansin veroorsaak
Bakteriese infekie
  • VRAE OOR GESLAGSIEKTES:

1. Watter van bostaande siektes kan suksesvol behandel word? Hoe?

2. Wat is die verskil tussen HIV-positief en VIGS?

3. Hoe kan 'n persoon wat HIV-positief is sy lewensverwagting verleng?

4. Wat is NEVIRAPIEN en waarvoor word dit gebruik?

Assessering: Vrae oor GESLAGSIEKTES

Kon jy die vrae suksesvol beantwoord?

Gesinsbeplanning en voorbehoeding

Aangesien paartjies deesdae verskeie redes het waarom hulle nie baie kinders wil hê nie, of dalk glad nie, is die voorkoming van swangerskap vir hulle baie belangrik.

Gesinsbeplanning is die konsep waar paartjies hul swangerskappe beplan – gewoonlik om die finansiële sekuriteit van hul kinders te verseker.

Meeste mense wil egter net swangerskap verhoed en pas dieselfde VOORBEHOEDINGSMETODES toe.

Voorbehoedingsmetodes

  • Daar is NATUURLIKE en KUNSMATIGE metodes:

Natuurlike:

  • ONTHOUDING – geen seks; 'n toenemend populêre metode – een van die enkele metodes wat 100% swangerskap verhoed, asook geslagsiektes uitskakel.
  • RITMIESE METODE – ovulasie en die temperatuurverhoging in die tyd word gebruik om òf swanger te word òf om dit te verhoed.

Kunsmatige:

METODE STATISTIES die getal SWANGERSKAPPE (uit elke honderd gebruikers)
KONDOOM : rubberskede wat om penis geplaas word 4
DIAFRAGMA : rubber skerm wat net voor omgang in vroulike sisteem geplaas word 3
IUD :(‘intra-uterine device’)Word deur dokter in uterus geplaas – bly maande daar 3
VOORBEHOEDPILLE "Die Pil" 0-2afhangend van gebruiksfoute
STERILISASIE :Buise word afgebind en geknip Feitlik 0

Klasaktiwiteit: BESPREKING van VOORBEHOEDING

1. Hoekom is gesinsbeplanning belangrik? Noem drie redes.

2. Hoekom is die ritmiese metode nie baie betroubaar as voorbehoedingsmetode nie?

3. Hoekom is onthouding as voorbehoedingsmetode besig om in gewildheid toe te neem?

4. Hoekom kan nie een van die kunsmatige metodes as 100% "veilig" beskou word nie?

5. Wat is:

a) 'n VASEKTOMIE

b) 'n HISTEREKTOMIE

c) SPERMDODERROOM

5. Gestel jy trou binnekort – hoeveel kinders sal jy wil hê en hoekom sê jy so?

6. Wat is jou siening oor ABORSIE? Onthou, elkeen is geregtig op sy opinie!

Assessering: KLASBESPREKING

Sien jy die verband tussen wetenskap en die sosiale gemeenskap waarin die mens bly?

2.3 inligting kan interpreteer;

2.4 kennis kan toepas.

LU 3

3.2 die volhoubare gebruik van die aarde se hulpbronne verstaan.

Memorandum

Gesinsbeplanning en geslagsiektes

VRAE OOR GESLAGSIEKTES:

1. Bakteriese infeksies kan met antibiotika behandel word

2. HIV + beteken persoon het virusinfeksie; VIGS is volle ontwikkelde siekte

3. Gesonde lewenstyl, oefening, baie vars groente en vrugte, medikasie wat virusontwikkeling onderdruk

4. Verhoed moeder na kind oordrag van virus tydens en na geboorte

KLASAKTIWITEIT: BESPREKING van VOORBEHOEDING

1. lewenskwaliteit, finansiele sekuriteit, lewensonkoste, opvoeding

2. siklusse kan wissel – nie betroubaar

3. enigste een met werklike waarborge; terugkeer na strenger morele waardes agv vrese oor HIV en ander faktore

4. almal feilbaar agv menslike faktor

5. a) afknip van spermbuise by man – sterilisasie

b) verwydering van uterus by vrou – sterilisasie

c) medisinale room wat gewoonlik saam met ander voorbehoedingsprodukte gebruik word

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.

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?

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
