Hypertension

Hypertension is a common health problem in the community. Many people who suffer from the disease, but did not realize it. Hypertension is a degenerative disease and hypertension is a disease that is usually handled with ease, but when on leave without treatment can cause more severe complications.The highest prevalence of hypertension were women (25%) and in men (24%). Data Riskesdas mention Hypertension is the number three cause of death after stroke and tuberculosis. Based on data in Puskesmas Kelurahan Warakas Tanjung Priok, North Jakarta District bulam during March - May 2009 from patient visits totaling 8353 people, there are 982 people who suffer from hypertension (11.7%)Based on statistical data and the level of severity that requires treatment as soon as possible to reduce morbidity and mortality and prevent complications that continues, then the writer is interested in providing nursing care, especially family Tn.M Tn.M on Rt 11 Rw 04 Warakas Kelurahan Tanjung Priok, North Jakarta District

GROWTH AND HUMAN MIND that is based on MYTH

Human curiosity can be satisfied it was not based solely on observation and experience. To satisfy the natural mind, the human they own their answers. For example: "Is the rainbow", because it can not be answered, they flirt with jawban that the rainbow is the shawl "Angel". So the appearance of new knowledge that is "Angel". Another example of "why the volcano eruption?, Not knowing the answers so they cooked up their own with the answer" the power of guung was angry. " So, here comes the new knowledge is called "ruling". By using the same line of thought comes the notion of "ruling" in the dense forests, large rivers, big trees, sun, moon or the existence of a giant who swallows the moon during the eclipse of the moon. New insights that have emerged and trust that what we call the "myth". The story is based on a myth called the "legend".

Natural science begins with curiosity, which is a human characteristic of Man has a curiosity about things around him, natural surroundings, moon, stars and the sun is viewed, even want to know about himself.
Such curiosity is not possessed by other creatures. Obviously would like rocks, soil, rivers or wind. Water and air are moving from one place to another, but it's not gerakanya own volition, but simply a result of its natural effect is everlasting.

SCIENTIFIC METHOD, SCIENTIFIC ATTITUDES AND ACTIONS OF OPERATIONS SCIENTIFIC METHOD

starting from the time humans Babylonians (approximately 650 BC) where people believe in the myths, predictions based on astrology's fate One goal in studying aspects of natural science is the formation of attitudes. People who engaged in natural sciences will form a scientific attitude among others are:

1. HONEST
It is a scientist must be honest in carrying out research reports and shall report the results objectively pengalamatannya.
2. OPEN
A scientist must have a broad view, open, free of preconceptions, and appreciate any new ideas and do not belittle and tested before being rejected or diterima.Jadi will open other people's opinions.
3. Tolerant
A scientist does not feel himself the most powerful even willing to acknowledge that others may be more knowledgeable, and maybe just one opinion, while other people's opinions right.

SCALES WEIGHT AND BODY WITH HIGH SOUND OUTPUT

In describing the design of signal processing hardware voltage generated by the measuring instrument in this case the load cell as a measure of weight and shear resistor resulting from the roll of the email system as a measure of height
At the height weighing system the ends of the coil is given shear stress, while shifting 5 volts using a ferrite rod which point the shift in the ferrite produces an output voltage based on the principle of voltage divider resistors
Teganganpengatur composition calibration circuit voltage generated by each sensor. thus has two functions is to enlarge the amplitude of the DC offset as well as its regulator.

Digital Techniques (Changing Code)

One application of logic gates within the system. Digital is a modifier code. Kodeyang commonly used is binary, BCD (8421), octal, hexadecimal, and, of course. only, decimal. A lot of 'mystery''which includes computers and other digital systems, derived from the lack of bahasarangkaian fahaman digital. Digital equipment can only process the bits I and 0. However, it is difficult to understand human
long sequences of units and zero's. For this reason, the required modifier code that we mengubahMarilah pehatikan simple block diagram of a handheld calculator in Figure 6-1.
Input devices on the board-km is the key (keyboard). Between the board and key processing unit
central CPU (central processing unit) of these calculators have a device called the coding
(Encoder). This coding change decimals on the board is pressed into a code-lock
binary code such as BCD (8421). mengedakan CPU operation in the binary and produce an
binary code. Pendekode (decoder) to change the binary code from the CPU into a special code that turns
appropriate section on the seven-segment display (seven-segment display). Thus, pendekode change
from binary to decimal. Coding and pendekode pentedemah on this system is an electronic code.
Coding can be considered as penedemah of human language into machine language. Pendekode know ~ will be the opposite: translating the machine language into human language

Digital Techniques (REGISTER SHEAR)

Shift register (shift register) is one of the functional devices The most widely used in digital systems
Shift registers are grouped as a sequence of logic circuits, and therefore the shift register composed of flip-flop.
The shift register used as temporary memory, and to penggesran data to the left or right, shift register is also used to convert parallel data into serial or parallel data into serial.
An identification method is how the data shift register dirnuat and read from the storage unit.
Each device penyimpnanan Which is shown in Figure 9-1 registers
1. Input and output series ~ Figure 9-1a)
2. Serial input, parallel output (Figure 9-1b)
3. Serial input, parallel output (Figure 9-1c)

Analog Digital Conversion

This chapter will discuss the task of mediation between analog and digital equipment. Especially will learn modifier A / D and D / A.Sering time digital system must diantarmukakan with analog equipment. Special coding called analog to digital converter, which means an analog input into digital information and digital inputs to the opposite analog.Tugas converter D / A is to transform the digital input into analog outputs. (Figure 13.2) illustrates the function of converting D / A. In summing amplifier in a converter D / A in particular we use the IC operational amplifier type is often called an op amp (operational amplifier)
Summing amplifier in the converter D / A using the op amp is a versatile amplifier and has the following important characteristics:
High input Impendantasi
Impendantasi low output
Amplifier voltage change - change that prices are set by external resistors

LOGIC TECHNOLOGY

Parameters and Limits logic components namely logic gates and memory are usually packed on an IC (integrated circuit) or chip. Two basic technologies in digital IC industry is bipolar and MOSFET (metal oxide semiconductor field effect transistors). MOS technology dominates the field of SSI (small scale integration) because with this larger number of MOSFETs can be packed in the same chip size, besides a very low power needs to give its own advantages for CMOS. A digital family is a component that is compatible with Iogika level and the same supply voltage. Compatible means can connect the output of a particular device with the input of other devices. This compatibility allows various combinations that differ in the number besar.Desain which are widely used in the past is the DTL (diode transistor logic)
using diodes and transistors. Design TTL (transistor-transistor logic) that
using the transistor current to the most popular family in
shale SSI and MSI (medium scale integration). While ECL (emitter coupled
logic) is the fastest logic family are widely used in
various applications that require high speed.

Computer Graphics Coordinate Systems

In computer graphics there are three kinds of coordinate system should be noted:
• real coordinates
• The coordinate system (Cartesian coordinates)
• Coordinate display / screen
Coordinates REAL (WORLD Coordinate)
Are the coordinates of the object at that time were concerned, eg the coordinates of a chair
depending on the location of the chair was where, how it is.
In real coordinates its implementation can be said as a WINDOW that is an area that shows the real world is seen by viewers.

Each point is drawn with a point-plotting techniques location is determined based on the Cartesian coordinate system.
Each point is determined location via paired values of x and y.
Where the value of a positive x coordinate increases from left to right and positive values of y increase from bottom to top.

Cartesian coordinate axis direction opposite to that used on a computer screen.
On the computer screen increases the positive x-axis to the right and positive y-axis increasing downward.
As in the following figure if a point on the Cartesian coordinates were redrawn to the screen then visually location point will be changed.

Digital Image Processing

Neighboring OPERATIONS / PERSEKITARAN (Neighborhood Operation)
An image of the ideal, if capable of reflecting the actual condition of an object.
Having a one-one relationship (one to one), one point on the object is mapped exactly one pixel in a digital image.
But in reality, the relationship that exists between the point in the object with a point on the digital image is one to many relationship (one to many) and many to one (many-to-one).
• This is because:
signals sent by the object image is spreading (divergence), so received by the sensor or detector no longer be a point, but the form of an area.
Or conversely one point on the sensor or detector can receive many signals from several parts.
Operation of digital image associated with the above mentioned operating conditions persekitaran / neighbors (neighborhood operation).
Operation persekitaran / neighbor is basically the relationship between the image with a filter (mask / kernel)
The value of the filter / mask is the weight contribution to the operation persekitaran persekitaran point.
Several image processing associated with this operation are:

1. Edge Detection (Edge Detection)
2. Image Refinement (Smoothing)
3. Image sharpening (Sharping)
4. Noise Reduction
5. Emboss Effect

Edge detection (Edge Detection)
This operation is used to determine the location of the points that represents the edge of the object image.
