00:00:09
good morning everyone my name is Robert
00:00:12
and this is Step today we're going to
00:00:14
talk about something we all familiar
00:00:16
with
00:00:17
smartphones what do you think of when
00:00:20
you see this Smartphone are best for you
00:00:24
that's what many people think but we are
00:00:26
not sure sure that's right so we are
00:00:29
going to talk talk today about the
00:00:31
impact of smartphones on human health
00:00:34
I'm going to give you some brief
00:00:36
background on the issue and explain the
00:00:39
negative impacts of smartphone on our
00:00:42
health then I will bring up some of the
00:00:45
positive impacts that smartphone have
00:00:47
had on human health since they were
00:00:50
invented after that I will give you a
00:00:52
quick summary of our findings and we
00:00:54
will answer any questions you may have
00:00:56
on the
00:00:58
issues okay first first of all let's
00:01:01
start by looking at use of smartphones
00:01:03
in our daily life two question first
00:01:06
what is a smartphone and what makes a
00:01:09
phone
00:01:10
smart
00:01:12
well this is Becker's definition of a
00:01:21
smartphone Google's research on
00:01:23
smartphone user behavior in 2013 show
00:01:26
that we do use our smartphone in our
00:01:29
daily life and VAR
00:01:31
situation which includes searching for
00:01:34
the information on the internet
00:01:36
communicating with each other and
00:01:39
keeping ourselves updated with news and
00:01:42
information entertainment and shopping
00:01:46
moving on to the situation in Hong Kong
00:01:48
the penetration of smartphone is quite
00:01:52
High according to the office of the
00:01:55
communication Authority in
00:01:58
2013 the six 5% of mobile phone users
00:02:02
were 3G or 4G service customers that
00:02:06
means there are 10.9 million smartphone
00:02:09
in using Hong Kong the reason that this
00:02:12
is more than the population of Hong Kong
00:02:15
is that many people own two or more
00:02:18
mobile
00:02:19
phones Google's research also found that
00:02:23
four out of five people in Hong Kong use
00:02:26
their smartphone every day and three
00:02:28
quarters of smartphone users carry their
00:02:31
phones with them at all times and the
00:02:34
smartphone becomes more popular and
00:02:36
people are spending more time on
00:02:38
smartphones debates have begun about
00:02:41
their usage one debate is on the
00:02:44
relationship between human health and
00:02:47
using smartphone so now I would like to
00:02:50
explore the points that's support this
00:02:53
statements I'm going to talk about two
00:02:55
main points first mobile phones may
00:02:59
damage bod structure researchers and
00:03:01
expert have pointed out that improper
00:03:04
use of smartphones may cause damage to
00:03:07
different body parts mirror in an
00:03:10
article from 2007 found that radiation
00:03:14
from mobile phones May produce extra
00:03:18
dative stress in brain tissue which can
00:03:21
lead to a higher risk of the brain
00:03:24
tissue damage and more research by the
00:03:27
team led by the lulis discovered in 2009
00:03:32
that radiation from mobile phones May
00:03:35
lower the fertility of males as the
00:03:38
radiation destroys the DNA and the
00:03:41
mobility of sperm cells the second
00:03:45
disadvantage of smartphone is that
00:03:48
smartphone apps may lead to a
00:03:51
misunderstanding of health issue a study
00:03:54
by O'Neal and breedy shows that a
00:03:57
considerable number of apps Rel
00:03:59
releasing health information without the
00:04:02
approval from medical professionals some
00:04:05
apps are designed for advertising
00:04:08
purpose and may contain misleading
00:04:11
information so smartphone users may also
00:04:14
have difficulty in distinguishing
00:04:17
between advertisement and verified
00:04:20
health information they may be misled
00:04:23
and buy some unsuitable Health
00:04:26
Products okay that's all I have to say
00:04:28
about the points that and evidence that
00:04:31
support the statement I've shown two
00:04:34
main points first the radiation of
00:04:37
mobile phone may cause damage to our
00:04:41
body which
00:04:43
includes brain tissue and the sperm cell
00:04:47
then the smartphone apps May spread
00:04:49
unreliable health information that may
00:04:53
mislead users now I should hand over to
00:04:56
Step who will discuss the point that go
00:05:00
against the statement step over to you
00:05:04
okay thank you Robert so I'm
00:05:06
step I'm going to introduce evidence
00:05:09
showing that smartphones are not harmful
00:05:12
to our health there are three main
00:05:14
points here first although smartphone
00:05:17
use May potentially be harmful to human
00:05:20
health smartphones can also help to
00:05:23
improve physical and psychological
00:05:26
Health the paper by Lee and colleagues
00:05:28
from 2012 argue that smartphones can
00:05:31
help monitor the body condition of
00:05:33
elderly patients smartphone allow user
00:05:36
to send data about their condition to
00:05:38
medical professionals and receive
00:05:40
medical advice anywhere at any time and
00:05:44
in case of an emergency smartphone
00:05:46
assists in locating the user by GPS or
00:05:48
mobile networks and can help to save
00:05:52
lives the second reason is that
00:05:54
smartphone apps May promote positive
00:05:56
behavioral health habits and improve
00:05:59
psychological Health as Lon and his
00:06:01
colleagues described in their 2011 paper
00:06:05
the apps can motivate user to engage in
00:06:07
healthy Behavior such as Sports and
00:06:09
keeping
00:06:10
fit another team from Spain have also
00:06:13
shown that smartphone apps have helped
00:06:16
in developing a healthy lifestyle by
00:06:18
using the apps regularly users were able
00:06:21
to develop a healthy hitting ERS within
00:06:23
three
00:06:24
months that bring us to the last point
00:06:27
that support the health benefit of smart
00:06:30
smartphone apps can enhance
00:06:33
psychological
00:06:34
Health Lon and his colleagues also point
00:06:37
out in the paper that smartphone
00:06:39
encourage communication between people
00:06:42
as they can browse social networking
00:06:44
sites anywhere and any time people who
00:06:47
are unwilling or unable to communicate
00:06:49
face to face can still can get support
00:06:52
from friends
00:06:54
online research let drive Park further
00:06:57
confirmed in 2012 that smartphone app
00:07:00
have positive effects on strengthening
00:07:02
the cohesiveness of social networks
00:07:04
among users because they are able to
00:07:06
maintain connection with each other all
00:07:08
the
00:07:10
time this may relieve psychological
00:07:12
pressure and anxiety and Foster
00:07:15
interpersonal
00:07:16
relationship well I think that covers
00:07:19
most of the thing we want to say about
00:07:20
smartphone use and human
00:07:23
health turning to the last part of the
00:07:25
presentation let me go over the key
00:07:28
points in our presentation we have
00:07:31
discussed the point that are for and
00:07:33
against the
00:07:34
statement frequent use of smartphone is
00:07:37
harmful to human health my partner
00:07:40
Robert talk about the point that support
00:07:43
the statement mobile phones may damage
00:07:45
body structures and smartphone apps may
00:07:48
lead to misunderstanding of health
00:07:51
issues I then explor the point against
00:07:54
the
00:07:54
statement smartphone help in monitoring
00:07:57
health and smartphone PR behavioral and
00:08:00
psychological Health taking all the
00:08:02
point into consideration it appear that
00:08:05
the positive side of using smartphone
00:08:08
awaits the negative side we do think
00:08:11
that smartphone should be used in
00:08:12
moderation but all in all we support the
00:08:15
use of using smartphone and disagree
00:08:17
with the argument that smartphones are
00:08:19
harmful to human health as a device um
00:08:23
can actually improve our health in
00:08:25
different
00:08:27
aspects okay that's all for our
00:08:29
presentation thank you for listening and
00:08:31
I hope you found it
00:08:33
interesting you can find more detail in
00:08:35

00:08:38
list and now we would like to open it
00:08:41
for discussion would anyone like to ra a
00:08:44
questions yes you have show us that
00:08:47
there is a high usage of smartphone in
00:08:50
Hong Kong is it also a global
00:08:52
Trend thank you for your question yes
00:08:55
it's a global Trend there is a data
00:08:58
showing that smart phone has become more
00:09:00
popular in many Society the research
00:09:03
results from International marketing
00:09:06
company gner showed that there were more
00:09:08
than 960 million smartphones sold in
00:09:13
2003 all around the world the company
00:09:15

00:09:21
2014 so we believe that the smartphone
00:09:25
will users will rise globally yes does
00:09:29
that answer your question yes thank
00:09:32
you okay is there any other
00:09:35
questions you have mentioned in your
00:09:38
presentation that radiation from phones
00:09:40
may damage body structures there was a
00:09:43
recent news story that reported that the
00:09:45
blue violet lights from smartphones may
00:09:48
cause
00:09:49
brightness so is there any way that we
00:09:51
can use the phone safely um that's a
00:09:54
good question well there is certainly a
00:09:57
safe way to use smartphone that is don't
00:10:00
overuse them doctors and optician have
00:10:03
said that the eyes problem resulting
00:10:06
from smartphone is caused by not
00:10:08
blinking enough and putting the
00:10:09
smartphone too close to your eye so they
00:10:13
have suggest that users um should take
00:10:15
regular breaks from using smartphones
00:10:18
hold the device in your hand and keep
00:10:20
the distance between your eyes and the
00:10:21
phone less than 30
00:10:23
cm yes they are all good points and
00:10:27
there are two more easy things suggested
00:10:30
by wh experts that we can do to reduce
00:10:33
the influence of rad radiation from
00:10:36
phones on our body first we should use
00:10:39
the wire or speaker when we are using
00:10:43
the phone and this keeps the phone away
00:10:45
from our hat second we can keep the
00:10:49
phone in our back instead of putting it
00:10:51
in the pocket or of our clothes this
00:10:54
will reduce the radiation that we may
00:10:57
receive from the phone have around
00:11:00
surgal crin yes that's fine thank you
00:11:04
