A case study of cinema management system project report..pdfKamal Acharya
A computer reservation system or central reservation system is a computerized system used to store and retrieve information and conduct transactions related to air travel, hotels, car rental, or activities. These systems typically allow users to book hotel rooms, rental cars, airline tickets as well as activities and tours. They also provide access to railway reservations and bus reservations in some markets, although these are not always integrated with the main system. For these systems to be accessible on mobile phones and computers outside the premises of the airport, cinema, train station or stadiums, they need to be on the internet or a network.
This project focuses on the design and implementation of a web based cinema management system for the allocation of seat tickets online. The system would feature the registration of users, use of serial numbers and pins gotten from scratch cards sold and a printed slip. The system would have a store of all the seats and automate the generation of fresh serial numbers and pins.

The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

2. Liver: Anatomy
•The liver is the largest visceral organ in the
body and is primarily in the right
hypochondrium and epigastric region,
extending into the left hypochondrium (or
in the right upper quadrant, extending
into the left upper quadrant).
•Surfaces of the liver include:
•a diaphragmatic surface in the anterior,
superior, and posterior directions;
•a visceral surface in the inferior direction 2
3. Position of the liver in the abdomen: Diaphragmatic surface
3
7. The Liver
•Is located in the upper right quadrant of the abdomen
•Cleans the blood
•Regulates hormones
•Helps with blood clotting
•Produces bile
•Produces important proteins
•Maintains blood sugar levels
•And much, much, more
• The liver is essential
for life !
9. Laboratory Studies
Serum enzymes
•Hepatic disorders associated predominantly with
elevation in aminotransferases are referred to as
hepatocellular; hepatic disorders with predominant
elevation in alkaline phosphatase (AP) are referred to as
cholestatic.
•Alkaline phosphatase is an enzyme that is present in a
variety of tissues (bone, intestine, kidney, leukocytes,
liver, and placenta).
•Elevation of serum aspartate and alanine
aminotransferases (AST and ALT, respectively) indicates
hepatocellular injury and necrosis.
•The ratio of serum AST to ALT is typically >2 in alcoholic
liver disease. In viral hepatitis, this ratio is
characteristically <1.
9
10. Synthetic products
•Serum albumin concentration is frequently
decreased in chronic liver disease.
•However, chronic inflammation, expanded
plasma volume, and gastrointestinal or
renal losses may also lead to
hypoalbuminemia.
•Because the half-life of albumin is relatively
long (20 days), serum levels may be
normal in acute liver disease.
10
11. Synthetic products
•Cholesterol is synthesized in the liver.
•Patients with advanced liver disease may
have very low cholesterol levels.
•However, in primary biliary cirrhosis,
levels of serum cholesterol may be
markedly elevated.
11
12. Excretory products
•Bilirubin is a degradation product of
hemoglobin.
•Total serum bilirubin is composed of
conjugated (direct) and unconjugated
(indirect) fractions.
•Unconjugated hyperbilirubinemia occurs as
a result of excessive bilirubin production
(neonatal or physiologic jaundice,
hemolysis and hemolytic anemias,
12
13. Excretory products
•Bile acids are produced in the liver and are
secreted into the intestine, where they are
required for lipid digestion and absorption.
•Elevated levels of serum bile acids are
specific but not sensitive markers of
hepatobiliary disease.
•Levels of individual bile acids are not useful
in the differential diagnosis of liver
disorders.
13
14. Imaging
•Ultrasonography is used to screen for dilation of
the biliary tree and to detect gallstones and
cholecystitis in patients with right-sided
abdominal pain associated with abnormal liver
blood tests.
•It can reveal and characterize liver masses,
abscesses, and cysts.
•Color-flow doppler ultrasonography can assess
patency( openness of vessel) and direction of
blood flow in the portal and hepatic veins.
•Ultrasonography is a frequently used modality
for screening of hepatocellular carcinoma.
14
15. Imaging
•Magnetic resonance imaging (MRI) offers
information similar to that provided by CT
scan and the additional advantage of better
characterization of liver lesions, fatty
infiltration, and iron deposition.
•It is the modality of choice in patients with an
allergy to iodinated contrast and renal failure.
15
16. Liver Biopsy
•Percutaneous liver biopsy can be performed
with or without radiographic (ultrasound or
CT) guidance.
•Suspicious liver lesions are usually biopsied
with ultrasonographic or CT guidance.
16
18. What Is Hepatitis?
•Hepatitis means inflammation of the liver
•Hepat (liver) + itis (inflammation)= Hepatitis
•Viral hepatitis means there is a specific virus
that is causing your liver to inflame (swell or
become larger than normal)
20. Viral Hepatitis
5 types:
A: fecal-oral transmission
B: sexual fluids & blood to blood
C: blood to blood
D: travels with B
E: fecal–oral transmission Vaccine
Preventable
Adapted from Corneil, 2003
21. Clinical Terms
•Acute Viral Hepatitis: symptoms last less than 6
months
•Acute Hepatic Failure: Massive hepatic necrosis with
impaired consciousness within 8 wks of onset of
illness.
•Chronic Hepatitis: Inflammation of liver for at least 6
months
• Cirrhosis: Replacement of liver tissue fibrosis,
scar tissue
•Fulminant Hepatitis: severe impairment of hepatic
functions or severe necrosis of hepatocytes in the
absence of preexisting liver disease
22. Pathophysiology
Targets of the hepatic viruses are hepatocytes:
•Hepatocyte uptake involves a receptor on the
plasma membrane of the cell
•After entry into the cell, viral RNA is uncoated,
and host ribosomes bind to form polysomes.
•Viral proteins are synthesized, and the viral
genome is copied by a viral RNA polymerase
•Lymphocytic infiltrate; varying degree of
necrosis.
23.
24. Classic presentation: infectious hepatitis
•Phase 1 - Viral replication; Patients are
asymptomatic during this phase.
•Phase 2 – Prodromal
•Phase 3 - Icteric phase
•Phase 4 - Convalescent phase; symptoms and
icterus resolve. Liver enzymes return to normal.
25. Clinical Evaluation: Acute Viral Hepatitis
1. Prodromal phase:
•Patients experience anorexia, nausea, vomiting,
alterations in taste, arthralgias, malaise, fatigue,
urticaria, and pruritus.
•When seen by a health care provider during this
phase, patients are often diagnosed as having
gastroenteritis or a viral syndrome.
2. Icteric Phase
•Jaundice, Patients may note dark urine, followed
by pale-colored stools.
•In addition to the predominant gastrointestinal
symptoms and malaise, patients become icteric
and may develop right upper quadrant pain with
hepatomegaly.
26. Clinical….
•Severe cases may result in Fulminant
Hepatitis:
1.Hepatic Encephalopathy: palmar
erythema, spider angioma
2.Hepatorenal syndrome
3.Bleeding diathesis
27. Clinical Evaluation: Chronic Hepatitis
-Occurs after acute Hepatitis in >80% of
people with HCV
-Some are asymptomatic, or have mild
symptoms; others may only present
with late complications (cirrhosis/HCC)
-Categorized based on grade of
inflammation, stage of fibrosis, and
etiology of disease
28. Physical Exam
•Low-grade fever.
•Significant vomiting and anorexia dehydration such
as tachycardia, dry mucous membranes, loss of skin
turgor, and delayed capillary refill.
•Icteric phase: icterus of the sclerae or mucous
membranes or discoloration of the tympanic
membranes.
•The skin may be jaundiced and may reveal urticarial
rashes.
•Liver may be tender and diffusely enlarged with a firm,
sharp, smooth edge.
29. Imaging Studies
•No specific imaging studies needed for diagnosis
• Appropriate diagnostic imaging studies (eg, ultrasound,
CT) if the differential diagnosis favors gallbladder
disease, biliary obstruction, or liver abscess.
Liver biopsy usually in cases of:
o The diagnosis is uncertain.
o Other coinfections or disease may be present.
o The patient is immunocompromised.
o Asses severity of chronic hepatitis B or chronic
hepatitis C.
30. •LFT: Elevation of serum transaminases not diagnostic, but useful
a)ALT elevated more than AST
b)Acute Hepatitis: ALT > 1000
c)Chronic HCV: ALT is generally lower than 1000
* Urine analysis: presence of bilirubin.
* Serum bilirubin: Total bilirubin may be elevated in infectious
hepatitis. Bilirubin levels higher than 30 mg/dL indicate more severe
disease.
* Alkaline phosphatase: if elevated significantly, consider
abscess or biliary obstruction.
* Prothrombin time (PT) if prolonged impaired synthetic
function of the liver.
* BUN & serum creatinine decreased renal function suggests
fulminant hepatic disease.
* Serum ammonia in patients with evidence of hepatic
encephalopathy.
* CBC: lymphocytosis
Lab Studies:
32. Hepatitis A
•Common cause of acute hepatitis
•Single-stranded, RNA enterovirus
•Transmission fecal-oral route; Contaminated
water and food
•The incubation period of hepatitis A virus is 2-7
weeks,
•AST & ALT levels usually return to reference
ranges over 5-20 weeks.
33. Hepatitis A..
•High risk Travellers: vaccinations;
passive immunoglobins given to those
exposed
•Mild self-limited disease and confers
lifelong immunity to hepatitis A virus.
•Chronic infection with hepatitis A virus
does not occur.
•Treatment: supportive
34. Diagnosis of HAV
•**Serum Serology: presence of serum
antigens and immunoglobins
•HAV: IgM anti-HAV: positive at the time of
onset of symptoms; results remain positive
for 3-6 months after the primary infection
•Anti-HAV IgG appears soon after IgM and
generally persists for many years.
35. Hepatitis C
•Spherical, enveloped, single-stranded RNA
virus
•170 million infected worldwide
•Parenteral Transmission: IV drug users
•Most common indication for liver
transplantation
36. Hepatitis C
•Usually clinically mild, does not cause
significant acute illness
•Fluctuating elevations of AST & ALT
•20% likelihood of developing cirrhosis
•50% likelihood of developing chronic
hepatitis
•Incubation period: 15-150 days, with
symptoms developing anywhere from 5-12
weeks after exposure.
37. Diagnosis of HCV
•HCV: Anti-HCV; cannot distinguish acute from chronic
infection
•EIA: antibodies against core protein and nonstructural
proteins; may appear 3 – 5 months after infection
PCR: used to detect viral RNA HCV
80% of cases: patients are asymptomatic and do not
develop icterus.
Treatment: Interferon alpha, Ribavirin; PEG-IFNs (better
sustained absorption, a slower rate of clearance, and a
longer half-life than those of unmodified IFN)
38. Hepatitis E
•Hepatitis E virus (HEV) RNA virus
• Enterically transmitted infection; fecal-oral
route, typically self-limited
•Most outbreaks occur in developing
countries.
•Incubation period of hepatitis E virus is 2-9
weeks
•Case fatality rate is 4%
39. Hepatitis E: diagnosis
•Serum, liver, and stool samples can be
tested for HEV RNA
•Anti-HEV antibodies:
-IgM (acute)
-IgG (chronic)
AST & ALT are elevated several days before
the onset of symptoms; return to normal
within 1-2 months after the peak severity of
disease.
Treatment: supportive
41. Hepatitis B(HBV)--EPIDEMIOLOGY
•HBV is a DNA virus
•2 billion people worldwide have past or present
infections
•400 million people are chronic HBV carriers.
•Eight genotypes of HBV identified and re-labeled A
through H.
•HBV is the cause of 60% to 80% of worldwide
Hepatocellular Carcinoma(HCC).
•500,000 to 1 million deaths worldwide are attributed
to it.
•5% to 10% of all liver transplants are attributed to HBV.
42. AT Risk Groups

44. Serology
HBsAg
• Present in acute of infection
• Detectable 1 to 2 weeks after infection
HBeAg (Soluble core associated antigen )
• Appears shortly after HBsAg
• Indicates viral Replication and Infectivity
HBsAB(Anti-HBS)
• Present after vaccination or clearance of HBsAg(Usually 1 to
3 months)
• Indicates immunity to HBV
Hb core Antibody (IgM anti-Hbc or IgG anti-HBc)
• Only Serological marker of HBV during "Window Period"
45.
46. Diagnosis
•Serology
•Liver Chemistry tests
•AST, ALT, ALP, and total Bilirubin
•HBV Viral DNA--Most accurate marker of
viral DNA and detected by PCR
•Liver Biopsy--to determine
grade(Inflammation) and stage(Fibrosis) in
chronic Hepatitis
47.
48. Progression
•Incubation Period: 30-180 days
•Acute HBV Infection: 90% resolve by themselves;
less than 1% develop fulminant hepatitic failure
•Chronic HBV Infection: 2-10% progress to chronic
state
•90% in under five children progress to chronic
state
•Risk of Liver Cirrhosis: 5 year accumulation risk
of 8% to 20%
•5% to 10% of people progress to HCC with or
without preceding cirrhosis; less than
5% achieve a chronic carrier state
49. Treatment of HBV

•Coinfection-self limited
•Superinfection-acute HBV carriers present with
severe acute hepatitis infection w/ increased risk
for HDV infection.
