Early heart disease detection using data mining techniques with hadoop map reduce Early Heart Disease Detection Using Data Mining Techniques with Hadoop Map Reduce
International audienceHeart and other organs are important parts in human body. As per World Health Organisation(WHO)'s statistics, the cause of death in all over world is mostly due to cardiovascular diseases. The reason behind this are sedentary lifestyle which may lead to obesity, increase in cholesterol level, high blood pressure and hypertension. In this paper, by using various data mining techniques, such as Naive Bayes(NB), Decision Tree(DT), Artificial Intelligence (AI), Neural Network (NN) and clustering algorithms such as Association Rules. Support Vector Machine (SVM) and K-NN algorithms are used to extract the Knowledge from the large number of data set. The generated reports help doctors and nurses to identify about disease and their levels with which they can provide a better treatment to the patient. Text Mining is most commonly used mining technique in health care industry. In this paper we compare K-means clustering algorithm with Map Reduce Algorithm's implementation efficiency in parallel and distributed systems

High intensity exercise training programme following cardiac transplant
A 26-year-old male patient who presented with symptoms of end stage cardiac failure as a result of dilated cardiomyopathy,
had an orthotopic cardiac transplantation. A comprehensive cardiac rehabilitation programme was provided to him and he
was introduced to a sport (tennis). The exercise training programme progressed from low intensity training to high intensity
programme over a period of 15 months. A cardio-pulmonary exercise test done 22 months after surgery suggested that he
was able to achieve the aerobic capacity comparable to that of a normal South Indian subject. He participated successfully
in the World Transplant Games in Sydney and returned safely. This suggests that after a proper cardiac rehabilitation
programme, patients undergoing heart transplantation can achieve normal physiological responses to lead a normal active
lif
Unusual bumper catch of shrimps at Nochikuppam, near Chennai, east coast of India
Sporadic occurrence of penaeid shrimps
consisting exclusively of Fenneropenaeus indicus
(Indian white shrimpтАУVella eral/Por eral),
F. merguiensis (banana shrimp тАУ Vella eral/
Sunnambu eral), Penaeus semisulcatus (green tiger
shrimp тАУ Valayampoota era/motta eral/vari eral/
flower), Penacus monodon (giant tiger shrimp тАУ
Kotteral/Kathamba eral/kara) are usually recorded
by indigenous gears like single-layer gillnet (Pannu
valai) and three-layer trammel net (Disco valai/Mani
valai). In these nets the shrimp catch rate vary from
2 to 5 kg/unit, while in the trawl net, shrimps form
10 to 15 % of the annual total fish along the Chennai
coast. However, an unusual bumper catch of shrimps
to a tune of 22.8 t was landed by trammel net at
Nochikuppam Landing Centre near Chennai during
10th - 14th December
Spurt in the landings of crabs along northern Tamil Nadu and Puducherry coasts
The marine crab fishery by mechanised trawlers
along the north Tamil Nadu (Chennai and Cuddalore)
and Puducherry coasts is mainly supported by those
belonging to the genera Portunus and Charybdis of
the family Portunidae. Species like Portunus
sanguinolentus, P. argentatus, P. gladiator,
P. pelagicus, Charybdis natator, C. lucifera,
C. variegata and Podopthalmus vigil are
commercially important. Of these, until the end of
October 2008, there were remarkable changes in the
landing pattern of trawl fishing along the north Tamil
Nadu and Puducherry coasts. The same change of
pattern was also seen in indigenous gears such as
gillnet, operated near the shore, locally called as
Nandu valai and Kallu valai in the depth range of
5 тАУ 10 m. In multiday long voyage trawl fishing, crabs
were caught in deeper waters up to 100 m. In single
day fishing, the fishermen operated up to 50 - 60 m.
In the crab exploitation there was heavy landings of
P. sanguinolentus and other portunid crabs along the
Tamil Nadu coast, while other fish categories were
poorly caught during the period. A brief account of
unusual heavy landings of the portunid crabs is
reported here
Trophic level of fishes occurring along the Indian coast
Data on the trophic level (TrL) of 707 species of exploited finfishes, crustaceans and cephalopods along the Indian coast were collected from different sources. The TrL ranges from 2.0 to 4.7 and the mean TrL is 3.5. The mean TrL of pelagic finfishes is 3.68, and the TrL decreased towards
demersal habitat (3.44). A strong positive correlation exists between maximum body length of finfishes and TrL. The mean TrL of exploitation was 3.25. The complexities of assigning TrL values are discussed
First report on the occurrence of the silky shark, Carcharhinus falciformis (M├╝ller & Henle, 1839) in commercial landings along the east coast of India
Silky sharks Carcharhinus falciformis (M├╝ller &
Henle, 1839) are large oceanic sharks, known to be
circumtropical in distribution, occurring mostly in
the subtropics between 40├ж%N and 40├ж%S. They are
highly migratory, known to inhabit continental and
insular shelves and slopes, deep water reefs, and
the open sea. They are also occasionally sighted in
inshore waters. They are solitary in nature and are
often found near schools of tuna, increasing the
chances of forming a bycatch of tuna fisheries. These
sharks have been reported in the fishery only along
the southwest coast of India, and were recorded in
small numbers at Cochin during 2000-2002. In 2010
however, this species formed about 16.3% of the shark
landings at Cochin. In spite of this, these sharks have
not formed a fishery along the east coast
Quantitative changes in bottom trawl landings at Kasimedu, Chennai during 1998-2007
During the period 1998-2007, an annual average of 20,898 t of
marine resources was landed by trawlers at Kasimedu, Chennai,
by expending a mean annual effort of 35,608 units. The annual
catch during 1998-2007 showed fluctuations between 12182 t
in 2005 and 35,838 t in 2002. The mean annual effort of 13.21
lakh h in 1998 dropped down to 5.08 lakh h in 2007; mean
annual catch declined from 36,364 t in 1998 to 17,293 in 2007.
Catch per hour (CPH) increased from 27.51 kg in 1998 to 33.98
kg in 2007, in spite of reduction in both. Multiday trawl units
which formed only about 8% of the annual operational units
during 1989-тАЩ91, accounted for 39% and 31% of the operational
units in 1998 and 2006, respectively. Seasonal abundance of
catch indicated that maximum catch was landed during the
third and fourth quarters of the year, which contributed to
34.2% and 25.1% of the annual average catch during 1998-
2007. Demersal finfish resources contributed maximum (38.1%)
to the annual average catch during the period 1998-2007
followed by pelagic finfish resources (25.4%), crustacean
resources (15.1%) and cephalopods (5.6%). Miscellaneous
finfishes and shellfishes accounted for about 15.8% of the
catch. The resources that regularly contributed to the bulk of the
catch were elasmobranchs, carangids, threadfin breams,
silverbellies, ribbonfishes, tunas, goatfishes, lizardfishes,
croakers, barracudas, clupeids, whitebaits, snappers, shrimps,
crabs and cephalopods
