Coding theory is a branch of mathematics that deals with the design and analysis of codes, which are used to transmit information over a noisy channel. In this case study, we will examine a real-world application of coding theory in the field of data storage and retrieval.
One of the main challenges in data storage is ensuring the integrity and reliability of the information being stored. This is especially important in situations where data loss or corruption could have serious consequences, such as in the case of financial records or medical records. One way to address this issue is through the use of error-correcting codes, which can detect and correct errors that may occur during transmission or storage.
One popular class of error-correcting codes is known as Reed-Solomon codes, which were developed by Irving Reed and Gustave Solomon in 1960. These codes are based on polynomial algebra and are widely used in many different applications, including CD and DVD storage, satellite communications, and deep space communication.
One specific application of Reed-Solomon codes is in the field of hard disk drives (HDD). HDDs are used to store large amounts of data on a spinning disk, which is accessed by a read/write head. However, due to the mechanical nature of HDDs, it is possible for errors to occur during the reading and writing process. This is where Reed-Solomon codes come in.
HDD manufacturers use Reed-Solomon codes to encode the data being written to the disk, adding an extra layer of protection against errors. If an error is detected during the reading process, the Reed-Solomon code can be used to correct the error, ensuring that the data is retrieved accurately.
In addition to their use in error correction, Reed-Solomon codes are also used in data fragmentation and interleaving. Data fragmentation involves breaking up large blocks of data into smaller chunks, which can be stored on different parts of the disk. This helps to reduce the impact of errors, as it is less likely that all of the fragments will be affected by a single error. Interleaving is a similar process, in which the data is rearranged in a specific pattern to spread out the errors and make them easier to correct.
In conclusion, coding theory plays a vital role in ensuring the reliability and integrity of data storage systems. The use of Reed-Solomon codes in hard disk drives is just one example of how coding theory is applied in the real world to solve practical problems and improve the performance of systems.

When that departure point is specific to nursing and when it is composed of assumptions, values and the six major units, it is a conceptual model. The inflammatory process increases intraluminal pressure, initiating a progressively severe, generalized or upper abdominal pain that becomes localized in the right lower quadrant of the abdomen within a few hours. Adam's conceptual model can be integrated in the nursing curriculum as basis for clinical case management; lastly, this study is recommended to be replicated by other nursing practitioners. We'll be happy to answer your queries Monday through Friday, from 9am to 5pm, Philippine Standard Time. Goals were formulated according to each source of difficulty and planned interventions were implemented and consequences were checked if there were changes in status happen after sources of difficulty were managed. The Researcher render 10 hours per day to complete the 50 hours intensive practicum.

Nursing practice, education and research always have some conceptual point of departure. As an explicit frame of reference, a model specifies that for which nurses must be accountable. As the precursor of a theory, a conceptual model for nursing is a global perspective for the discipline. Eventually, the inflamed appendix fills with pus that causes perforation if no management initiated at an early stage. In appendicitis, the appendix becomes inflamed and edematous as a result of either becoming kinked or occluded by a fecalith ie, hardened mass of stool , tumor, or foreign body. A programme that has several conceptual bases may, on the contrary, be anti-pedagogical.
Adam's conceptual model for nursing in the care of postoperative client suffering from ruptured appendicitis with generalized peritonitis.
. A pattern is sequence of related behaviors that assists the nurse in collecting and categorizing data. The following sources of difficulty were identified base on the three dimensions; For biological, Acute pain, difficulty in breathing, difficulty in moving, fluid and electrolyte imbalance, self-care deficit: grooming and hygiene, risk for infection, risk for imbalance nutrition less than the body requirement, hyperthermia. A conceptual model for a discipline is a very broad perspective, a global way of looking at a discipline. Before the researcher started the 50 hours intensive practicum a letter of approval was sent to the Dean, Graduate School through the Dean, College of Nursing and a letter was sent to the Chief Nurse, Vicente Sotto Memorial Medical Center. .
