Occupational Health and Safety (OHS)
 Refers to the legislation, policies, procedures and activities that aim to protect the
health, safety and welfare of all people at the workplace.
 OHS Policy is simply a method of stating how you, your employees, contractors
and visitors are expected to behave when they are on Company property or
performing Company related activities. As an employer or responsible contractor,
you are required by law to provide a ‘safe system of work’.
Occupational Health and Safety Policy and Procedures Before and
During Assembling Computer System
Reminders before you start disassembling your computer tower to keep both
your unit and yourself safe. And always remember on these “doesn’t fit doesn’t
belong”.
 Do not work alone so that there’s someone who can take care of you in
case of accident or emergency.

 Always power off and unplug the computer before working on it.
 Take off any metal objects on your arms or fingers such as bracelets, rings
or watches. Even if your unit is unplugged, there may still be some
remaining electric charge.
 Always ground or discharge yourself before touching any part of the
computer (such as the computer casing) and make sure your hands are
completely dry to avoid damaging any mechanical parts as well as to avoid
electrocution.
 Be careful with the tools that may cause short circuit (such as screw
drivers)
 Handle all parts with care. Place each piece you remove carefully down
onto a stable surface, if a component does not come out easily, do not use
excessive force if things don’t quite slip into place or when you’re removing
it. Instead, check if you are removing it correctly and no wires still
connected in the hardware.
 Always full the cable connector on the handle and not on the cable itself
 Be sure you’re standing in a dry place and use only rubber shoes when
standing on the ground or in a concrete floor.
 Make sure that the pins are properly aligned when connecting a cable
connector.
 Take away any liquid such as mineral water or soft drinks near your
working area or near computers, the three of the most damaging things to
a computer are moisture (sweat, drinking water), shock (electric or from
being dropped) and dust (any debris from household dust to bits of food).
 Personal protective equipment is correctly used in accordance with
organization OHS procedures and practice.
 Hazard/risks in the workplace and their corresponding indicators are
identified to minimize or eliminate risk to co-workers, workplace and
environment.
 Take necessary precautions to protect the component of the computer
from damaged cause by Electrostatic Discharge (ESD).
 Hold the components by edges and do not touch the IC’s.

PPE
(PERSONAL PROTECTIVE EQUIPMENT)
 It is equipment that will protect the user against health or safety risks at
work. It can include items such as safety helmets, gloves, eye
protection, high-visibility clothing, safety footwear and safety
harnesses. It also includes respiratory protective equipment (RPE).
 It is also be used to protect the working environment from pesticide
application, pollution or infection from the worker (for example in a
microchipfactory).
 It is important that students and teachers during their laboratory period
should be required to use PPE.Some of these are:
 Goggles A large spectacles, with
shields around the rims, for
protecting the eyes from dust,
excessive light, wind, etc.
 Rubber Sole A special type of
shoes used to prevent electrical
shock and for waterproofing and
insulating purposes.

 Apron A garment worn over the
front of the body as a protection for
one’s cloth.
 Face Mask A covering for the face
to prevent the inhaling or absorbing
dust and other chemicals.
 Gloves The covering material with a
separate sheath for each finger used
for hand protection.
Why is PPE important?
Making the workplace safe includes providing instructions, procedures, training and
supervision to encourage people to work safely and responsibly.
Anti-Static and Safety Precautions
The little shock you experience while you are walking across a carpeted floor
or when you touch a door knob, table, counter or even another person is a result of
static electricity. Static electricity is the discharge of electricity between two objects
with different electrical potential. Humans can’t feel a static shock until it is several
thousand volts strong, but it takes less than 30 volts to fry a sensitive computer
component, such as stick of RAM or a processor.

That’s why computer technicians and home computer builders have to guard
their computers against the deadly ravages of static electricity, as well as take steps
to avoid injury.
Safety and Anti-Static Rules
Always use an anti-static wrist strap when working on a computer (except
when working on monitors).
Anti-static wrist strap is used to make sure that the voltage difference in
your body and the computer is balanced out. By grounding your body with an anti-
static wrist strap, any excess static charge in your body will be dissipated right away.
How to use an Anti-Static Wrist Strap / Wristband
1. Grounding the Anti-Static Wrist Strap to the Power Supply.
Wear the strap with the metal part touching your skin.
NOTE: You can have it worn anywhere in your body; not just in your hand.
2. Turn your power supply OFF and plug the power cord to the outlet.

3. Clip the alligator clip on a power supply screw or you could have it
clipped on the grills of the PSU fans.
NOTE: Any metal should do as long as it is bare metal and not
painted metal as some paints have insulating contents while
othersdon’t.
4. Check that it is clipped firmly. Once everything is set right, you should have
the assurance that you are grounded and that any charge should be
dissipated right away.

 CPU (Central Processing Unit) -
The processor is the main “brain” or
“heart” of a computer system. It performs
all of the instructions and calculations that
are needed and manages the flow of
information through a computer.
 Primary storage-(internal storage, main memory or memory) is the
computer's working storage space that holds data, instructions for processing
and processed data (information) waiting to be sent to secondary storage.
Physically, primary storage is a collection of RAM chips.
Two (2) Types of Memory
a. ROM – (Read Only Memory) ROM is non-volatile, meaning it holds data
even when the power is ON or OFF.
b. RAM – (Random Access Memory) RAM is volatile, meaning it holds data
only when the power is on. When the power is off, RAM's contents are lost.

 Expansion Bus- A bus is a data
pathway between several hardware
components inside or outside a
computer. It does not only connect
the parts of the CPU to each other,
but also links the CPU with other
important hardware.
 Adapters- Printed-circuit boards
(also called interface cards) that enable
the computer to use a peripheral device
for which it does not have the necessary
connections or circuit boards. They are
often used to permit upgrading to a new different hardware.

Disassembling and Assembling Computer Hardware
1. Identify the procedures on how to disassemble and assemble computer
hardware.
2. Know the correct handling of computer hardware.
3. Perform disassembling and assembling of computer hardware.
System Unit Disassembly Procedure
This is one of the most important things to learn in taking the TESDA NC II
Computer Servicing Exam. You need to learn the step by step procedure on how to
open and disassemble a system unit. There are various design of computer casing
and before opening you need to check and see how you will start the system
unit dis-assembly. Here we are going to use a mini-tower casing as our model, mini-
tower casing design is the most easiest to disassemble, however that would depend
on the brand and model.
 It's Not a Race, take a slow relaxed approach, discuss, question and research
each component as it's removed.
 Fall back on your own knowledge, use the Internet, your books and resource
material. It's impossible to retain all the information, so one of the most important
computer skills you can learn is how to research and use your resources to find what
you need.
Questions to Think About or Discuss as you Disassemble
 Should I document everything I do or everything I remove?
 Am I taking the best ESD precautions available to me right now?
 When you remove an expansion card what kind of card is it?

 When removing a drive, what kind of drive is it?
 When removing wires or cables, what are the cables for?
 Am I still taking proper ESD precautions and is my anti-static strap still hooked
up?
 Look at the motherboard again when there's not so much in the way. Can you
point out the CPU?
Before You Begin
 Have a pen and paper ready. Documentation is real important.
 Make sure you have the tools you need and they're all close by and handy.
 Be sure to have a container to keep the screws in.
 Make sure you have the resource material, drivers or software that you may
need.
 If possible, enter the CMOS setup and record the information available.
 Disassembly is major surgery, do a full backup of the system.
Step1. Unplugging - The first thing you do is to unplug every cable that is plugged
in to your computer. That includes the cables such as Power, USB, Mouse,
Keyboard, Internet, Ethernet, Modem, AMFM Antenna, Cable TV, etc. Just unplug
all the cables for safety purposes.
Now that your computer is fully unplugged, move your PC to a clean work
space, preferably a carpet. The carpet is better than tile, because screws and other
small parts will roll around.
 Switch off the power supply and detach power cable

the computer. On most computer cases, there will be large knobs that you can
unscrew by hand or by screw driver on the back-right side of the computer. The left
side has small screws because on that side you can't access much on the inside.
 Remove the CPU cabinet cover
How to Remove the System Unit Cover
The standard way of removing mini-tower cases used to be to undo 4-6
screws on the back of the case, slide the cover back about an inch and lift it off. If
there is no manual, then a little time taken for careful inspection may be in order.
Here are some things to remember:
 Don't Force Anything. If it has to be forced, it will probably break. If there are
no screws on the back of the case for the cover, check the plastic face-plate on the
front. Some pry off to reveal screws or release levers (remember, careful inspection).
If everything on the front has its own bezel around it (including the LEDs) then
maybe the plastic front pops off (or maybe the case slides off the front).
 Make sure any screws removed are for the cover. You don't want to
unscrew the power supply by accident and have it fall inside your computer. That's a
bad thing.
 After the case is removed, place it in a safe place, where it won't get knocked
of a table, kicked or stepped on and bent.

Step3. Power Supply - The first thing to do is unplug every wire coming from the
power supply. You must disconnect the motherboard (very large connector/plug),
CD/DVD drive(s) power, internal hard drive power and portable hard drive slot
power.
Once everything is unplugged, unscrew the four screws holding the power
supply in place, on the back of the computer. Next, push the power supply from the
outside, and then lift it out
How to Remove Internal Power Supply
 Make sure it's unplugged.
 All power connectors should be removed, including the connection to the
motherboard and any auxiliary fans. Watch the little plastic tabs on ATX connectors
(you’d rather not break them). AT power supplies have a two piece power connector
that may be labeled P-8 and P-9. Make note of the orientation. The black wires
should be in the middle, black to black.
 Remove the connection to the remote power switch at the front of the case.
Orientation of the colored wires at this switch is critical. Make sure you document
well, and during re-assembly plug the computer into a fused surge protector before
turning it on (this could save your motherboard and components from melting if
you've reconnected improperly). If you're putting the same power supply back, it's

better to remove the entire switch and leave the connectors intact. The remote
switch on an ATX form factor attaches to the motherboard.
 Remove the four screws at the back of the case and gently slide the power
supply out of the case. While removing these screws, hold onto the power supply.
You don't want it falling into the case.
Step4. Memory (RAM) - To remove the RAM, push down on both tabs holding the
RAM in place, which are located at both ends of the RAM.
How to Remove Memory Module
Memory modules are one of the chips that can be damaged by as little as 30
volts. Be careful of ESD and handle them only by the edges. SIMMs and DIMMs are
removed differently:

 SIMM - gently push back the metal tabs holding the SIMM in the socket. Tilt
the SIMM away from the tabs to about a 45% angle. It should now lift out. Put each
SIMM in its own protective bag.
DIMM- There are plastic tabs on the end of the DIMM socket. Push the tabs down
and away from the socket. The DIMM should lift slightly. Now you can grab it by the
edges and place it in a separate antistatic bag.
Step5. Hard Drive - First, unplug the connector at the back of the slot, and unplug
the other end from the motherboard. Also unplug the SATA cable from the
motherboard and the hard drive. The portable hard drive slot is secured the same
way the CD/DVD drive is, with a tab. Pull on the tab, then slide the slot out.
To remove the hard drive from the side of the slot, unscrew the four screws
securing it in place. You must be very careful not to drop the hard drive, since it is
very delicate!

Step6. CD/ DVD Drive(s)- First, unplug the ribbon from the back of the drive. Once
that is completed, pull on the tab securing the drive in place, then push it out from
the inside.
How to Remove Drives From System Unit Bay
 Removing drives is not that difficult. They usually have a power connector and
a data cable attached from the device to a controller card or a connector on the
motherboard. CD-ROMs may have an analog cable connected to the sound card.
 The power will be attached using one of two connectors, a large Molex
connector or a smaller Berg connector for the floppy drive. The Molex connector may
need to be wiggled slightly from side to side while applying gentle pressure
outwards. The Berg connector may just pull straight out or it may have a small tab
that has to be lifted with a tiny flat screwdriver.
 The data cables need to be documented. Remember the pin one rule. Know
where each one goes before you pull it out and record its orientation (which side is
the stripe on, where is pin 1?). Pull data cables gently and carefully.
 Can the entire drive bay be removed? Does the drive come out the back of
the bay or does it slide out the front. If a bay is removable, you may have to remove
some screws or unclip a lever then slide the bay back and off. If the bay is not
removable, there should be access ports on the other side of the case that allow for
access to those screws.

Step7. Removing the System Fan - First, unplug the fan from the motherboard.
You can find the plug by following the wire from the fan. It should be labeled
"SYS_FAN1". Next, you will have to unscrew the fan from the outside. You should
now be able to lift the fan out of the PC.
Step8. Removing the CPU Fan- The CPU
fan is located right on top of the CPU heat
sink, which is a large piece of metal with
fins on the top. The CPU fan plugs into the
motherboard in an awkward place, that is
hard to access. But just follow the wires
and you should easily find it. It is labeled
"CPU FAN1". To remove the fan from the
heat sink, remove the four screws securing it in place.
Step9. Motherboard - The motherboard
has seven screws holding it to the frame,
which are indicated by large white circles
around them. Remove them and then lift
the motherboard out of the frame.

How to Remove Mother Board
 Document and remove all wire attachments to the motherboard. (Some of
these have Pin 1 designations also.)
 Most cases have a removable panel that the motherboard is attached to. By
removing a couple of screws the panel can be taken off and you can gain much
better access to the motherboard. Again, a little investigation can save a lot of
trouble.
 There is usually 2 or 3 screws holding down newer motherboards. Make sure
you've got the right ones and remove them.
 Motherboards sit on plastic or brass standoffs that keep the traces and solder
from touching.
Step10.Clean the system unit chassis with your brush, also clean your motherboard
and the rest of the peripherals being removed.

To Assemble
1. Provided that all peripherals are clean and ready. We are now going to assemble
your computer. In assembling back your computer, what we have done during
disassembling is just doing the reverse order to assemble it. Since the motherboard
was last to be removed, it should then be the first to put back. Remove the retaining
screws from the standoff screws of the motherboard and let the motherboard seat on
it with the ports facing out towards the I/O shield. Lightly push the motherboard to set
its ports to the holes of the I/O shield. Put the retaining screws on the motherboard
screw holes but do not tighten it yet. Now be careful in doing this one and if this is
your first time doing it, it is best if you lend a hand for assistance. Lightly push the
motherboard towards to I/O shield and lightly tighten the motherboard retaining
screws alternately until all screws are tight enough but not too tight. This is to ensure
that your ports are protruding correctly out of the I/O shield.
2. Once the motherboard is secured, put back the FP, Audio, and USB header
connectors as you will be using your documentation for reference.
3. Put back the drives to the correct drive bays.
4. Connect back the RAM, Video Card and other card peripherals to its proper slot
inserting it properly and some cards will require screws to be secured.
5. The data cables (IDE, SATA, floppy cable) should be connected to its proper
headers and drives. Remember the proper configuration of the placement of the
cables specially if you are dealing with the IDE cables.
6. After the data cables are properly connected, put back the power supply and
secure it with the screws you removed earlier. After securing the PSU to the chassis,
connect the power connectors to the drives and the motherboard.

7. Once all peripherals are connected properly, have a final inspection by visually
checking for loose connection or improper connection. Once the system unit
connections are thoroughly checked and verified, connect the keyboard; the monitor,
and the power connector then power up the computer. This initial powering up of the
computer while the side cover is open ensures us that everything is ok before putting
back the side cover. In case something goes wrong, we can accessibly correct the
problem right away. If everything is fine shutdown the computer, unplugged the AVR
and remove the cables connected to the back of your computer. Put the side cover
back.
8. Put the assembled computer back to its place and connect the rest of the cables
and connectors. Power it up and see if there are unusual effects of your
disassembling/assembling procedure done earlier.
Step by Step Computer Assembly(NEW)
Step 1. Prepare your workplace
1. Take Inventory: Before you start, take an inventory of your parts. Do not begin
assembling your computer if you don't have everything you need. Begin the step-by-
step process once you are ready with everything you need.

2. Make Space, Make Time: Building a PC takes up space - about a dining room
table worth. So make sure you have plenty of working room and a few hours to
proceed with minimal interruption. Work on a flat, stable table top surface, or bare
floor, where you have room to layout all of the items.
3. Prepare Grounding Protection: Use an inexpensive antistatic wrist strap. It is
the perfect preventive measure if you have no alternative to working on carpet.
Remember, a table top or bare floor is always the best place to build your system.
Make sure you are wearing your antistatic wrist strap correctly (it does you no good
at all if you do not wear it!), and you are ready to proceed.
4. Have the Drivers Ready: Assuming you have another internet connected PC,
download the latest drivers from the vendors' websites for each component you will
be installing. Sometimes drivers are updated between the time the component was
manufactured and the time you are installing it. It is always best to have the latest.
Copy them to a CD for easy access.
Step 2. Prepare the Motherboard
1. Great care should be taken when installing the motherboard. First, take the board
out of its packaging and put it on top of the antistatic bag it came in (see Figure 45).
Remember, you always want to safeguard your components from potentially
hazardous static electricity (wear your strap).

2. Before you secure the motherboard onto the PC case/chassis, inspect it carefully
for any visible defects. 3. Next, review the motherboard manual, to make sure you
are familiar with the motherboard layout and understand which socket is which.
Manuals are extremely helpful, usually easy to read, and include illustrations. Below
you can find instructions on how to install the processor, the heat sink and the
memory modules on the motherboard. You should not place the motherboard in the
computer case until you are told to do so.
Step 3. Install the CPU
1. Use the unlocking mechanism to
open the CPU socket which is usually a
lever.
2. Carefully line up the pins and place
the chip in its socket; it will fit only when
oriented the proper way. An arrow or a
missing pin on one corner of the chip
will show you how to line things up.
3. Align Triangular CPU and socket key
marks. Lower the lever to lock the CPU
into place.

Step 4. Install the CPU Heat Sink
1. Follow the manufacturer's directions to install the heat sink and the fan that will
cool the processor. If you bought an OEM CPU and a separate heat sink, you may
need to spread a thin layer of the thermal grease that came with the heat sink over
the chip to ensure proper transfer of heat (some heat sinks come with this grease
already applied).
3. Attach the clip that holds the heat sink in place keeping in mind that it may require
a fair amount of force. Again, follow the instructions that came with the heat sink.
They will show you how to fit it correctly. If you are in doubt, you can visit the
manufacturer's website for more information.
4. Plug the CPU fan's power connector into the proper connector on the
motherboard.
Step 5. Install Memory (RAM Modules)
In order to install the memory
modules, insert them into the proper
sockets (Figure 48) and push down firmly
but evenly until the clips on both sides of
the socket pop into place. If your
motherboard supports dual-channel
memory, consult the user manual to

determine which pairs of RAM sockets you should use. The motherboard and the
CPU are the brain and nerve center of your PC, so selecting these components is
the most important decision you'll make.
Step 6. Place the motherboard into the case
1. Some PC cases have a removable
motherboard tray. If yours does, remove the
screws holding it in place and pull it out of the
case.
2. Note the pattern of the holes in your
motherboard (Figure 50), and screw brass
standoffs into the motherboard tray or into the PC
case in the correct locations (ALWAYS check the
manual and follow their instructions to the letter).
3. Check the layout of the sockets on the motherboard, and confirm that the ports on
your motherboard's back panel match the holes on the case's Input/output (I/O)
shield that is installed in your case. If necessary, remove the old I/O shield by
tapping it firmly a few times with the butt-end of a screwdriver, and then replace it
with the shield that came with the new motherboard.
4. Carefully position the motherboard on top of the brass standoffs (Figure 51), line
up all the holes, and use the screws that accompanied the case to fasten down the
motherboard. If you are using a removable tray in your system, slide the tray and
motherboard back into the case and then secure the tray.

Step 7. Connect the Power Supply
Making the proper connections is crucial to successfully assembling your PC system.
Fortunately, manufacturers provide color-coded power cables and unique connector
shapes to make the job easy.
1. First, plug the large ATX power connector (Figure 53) from your power supply into
the matching port on your motherboard. Look Figure X for details.
2. Locate the smaller, square processor power connector (Figure 54) (you cannot
miss it - it is the one sprouting the yellow and black wires) and attach it to the

2. Install the graphics board in that slot, and then secure the card with a screw.
Step 9. Install Internal Drives
Now it is time to install your drives. This is an easy process, but it requires attention
to detail.
1. Make any necessary changes to jumpers on the drives before mounting them in
the case. A two-drive system (one or two SATA (Serial ATA- is a standard hardware
interface for connecting hard drives and CD/DVD drives to a computer) hard drives,
plus one parallel ATA (Advanced Technology Attachment) optical drive, for example)
is easy to set up; the SATA drives are jumper less, and the optical drive can be set
as master on its own parallel ATA channel. Many cases have removable drive rails
or cages to house drives.
2. Use the included screws to attach your drives to the rails or cage, and slide them
into the case. For externally accessible drives such as a DVD recorder, you can save
time by installing one drive rail and sliding the drive in for a test fitting to make sure
that its front is flush with the case (Figure 59).
3. When the drives are installed, connect
power and data cables to each one. Parallel
ATA drives use wide, flat data cables that can
be installed only in the correct way. Floppy
drives use a similar but smaller cable; SATA
drives use a thin, 1cm-wide data cable. SATA
drives use a new type of power connector

that many power supplies don't come with. Fortunately, many motherboards ship
with adapters for converting a standard four-pin power connector to a SATA power
connector.
Attach your devices
Step 10. Install the Add- in Cards
1. For each add-in card, you must choose a free PCI slot.
2. Remove its backplane cover to allow access from the rear of the case.
3. Carefully position the card above the slot, and press down firmly to seat the card.
4. Secure the card with a screw.

Many motherboards have additional sound connectors or ports housed on
small add-in boards. Some of these plug into slots on the motherboard; others screw
into the back of the case in place of slot covers. Usually the additional ports are not
essential to your PC's operation. For example, if you install a sound card, you do not
need connectors to the motherboard's built-in sound chip. Check your motherboard
manual to determine what each of these boards does.
Connecting Peripherals of a Personal Computer
When attaching hardware and peripherals of the computer, ensure that they
are connected to the correct locations or ports. For example, some mouse and
keyboard cables use the same type of PS/2 connector. So, you must know first the
different ports that can be found in the back panel of the computer.
Keep in mind: 1. When attaching cables, never force a connection. 2. Plug in the
power cable after you have connected all other cables.
STEPS IN CONNECTING EXTERNAL HARDWARE OF A PC
Step 1. Attach the monitor cable to the video port.
Step 2. Secure the cable by tightening the
screws on the connector.

bottom-right corner of the screen and click Restart.
 If your computer is already off, press your computer's "On" switch.
STEP 2.Wait for the computer's first startup screen to appear. Once the startup
screen appears, you'll have a very limited window in which you can press the setup
key.
 It's best to start pressing the setup key as soon as the computer begins to restart.
 If you see "Press [key] to enter setup" or something similar flash across the bottom of
the screen and then disappear, you'll need to restart and try again.
STEP. 3 Press and hold Del or F2 to enter setup. The key you're prompted to
press might also be different; if so, use that key instead.
 You'll typically use the "F" keys to access the BIOS. These are at the top of your
keyboard, though you may have to locate and hold the Fn key while pressing the
proper "F" key.

 You can look at your computer model's manual or online support page to confirm
your computer's BIOS key.
STEP 4. Wait for your BIOS to load. After successfully hitting the setup key, the
BIOS will load. This should only take a few moments. When the loading is complete,
you will be taken to the BIOS settings menu.
Adjust settings
STEP 1. Familiarize yourself with the BIOS controls. Since BIOS menus don't
support mouse input, you'll need to use the arrow keys and other computer-specific
keys to navigate the BIOS. You can usually find a list of controls in the bottom-right
corner of the BIOS homepage.
STEP 2.Change your settings carefully. When adjusting settings in your BIOS,
be sure that you certain what the settings will affect. Changing settings incorrectly
can lead to system or hardware failure.

change coming into the BIOS, you
probably shouldn't change anything.
STEP 3. Change the boot order. If
you want to change what device to
boot from, enter the Boot menu. From
here, you can designate which device
the computer will attempt to boot from
first. This is useful for booting from a
disc or flash drive to install or repair an
operating system.
 You'll typically use the arrow keys to
go over to the Boot tab to start this
process.
STEP 4. Create a BIOS password.
You can create a password that will lock
the computer from booting unless the
correct password is entered.

amount of trash we make, reusing is finding a new way to use trash so that
we don't have to throw it out, and recycling is using trash to remake new
goods that can be sold again.
 5S – (Seiri, Seiton, Seiso, Seiketsu and Shitsuke) 5S is a simple tool for
organizing your workplace in a clean, efficient and safe manner to enhance
your productivity, visual management and to ensure the introduction of
standardized working.
 64-bit- 64-bit refers to the number of bits (the smallest unit of information on
a machine) that can be processed or transmitted in parallel, or the number
of bits used for single element in a data format.
 AGP- Short for Accelerated Graphics Port, an interface specification
developed by Intel Corporation. AGP is based on PCI, but is designed
