A Secure Methodology to Detect and Prevent Ddos and Sql Injection Attacks
As most of the applications host on cloud, Security is a major concern for the data owners. The cloud environment has to be secure and protect data owner data from cloud attacks. In this project work, we study about securing firewall against client side attacks namely Denial of firewall and SQL injection attacks. Denial of firewall is nothing but overloading the firewall by bursting n number of requests through vulnerable scripts. SQL injection attack is defined as bypassing the security protocols by malicious scripts. Thus we proposed to design and develop a web application to detect and prevent denial of firewall and SQL injection attacks.
The denial of firewall attack can be performed using Java environment based servers and prevention can be performed using Digital Signature Algorithm (DSA) in which filter based approach and software puzzle based approach are performed to detect the malicious script based requests. Once the Deep Packet Inspection (DPI): filter based approach and software puzzle based approach are find satisfactory only the request would be processed. If the request is find malicious automatically the requested IP address would be blocked. Various type of SQL injection attacks namely SQL login bypass, Blind injection, SQL sleep attack, Data fetching attack are analysed and performed. The SQL injection attack can be prevented using PREPARE statements. This statements are created to make the SQL queries more efficient and render security benefits. This statement provides effective prevention mechanism against SQL injection attacks. Thus our proposed solution, provides high security against firewall attacks namely denial of firewall and SQL injection securing the data owner files and preventing compromising of firewal
The Bethesda System of Reporting Thyroid Cytopathology and Its Histopathological Correlation
INTRODUCTION :
Fine needle aspiration cytology, is an initial investigation in evaluation of thyroid lesions. Due to lack of standardized system for reporting thyroid lesions in cytology in 2007, “The Bethesda System for Reporting Thyroid Cytopathology(TBSRTC)” was introduced. It is a six tier system.
AIM :
To classify thyroid FNACs based on “The Bethesda system” and to compare the results with histopathology.
OBJECTIVES :
To analyse thyroid cytology through TBSRTC and analyse distribution of lesions in various categories and to correlate the same with histopathology.
MATERIALS AND METHODS :
The study is a cross sectional study done in Department of Pathology, Coimbatore Medical College from July 2015 to June 2016.
OBSERVATION AND RESULTS :
• A total of 143 cases were studied, 108 were females and 35 males.
• Age of patients ranged from 9 to 80 years. Majority in 31- 40 years.
• Adequacy rate was 96 %.
• 119 cases were non – neoplastic, 19 cases were neoplastic, and 5 cases -unsatisfactory.
• Category II had maximum number of cases (119), majority was colloid goiter (70 cases).
• No cases in the category III.
• Category IV - 13 cases, among them 7 cases benign in histopathology, 4 cases - Papillary carcinoma, 1 case each of Follicular carcinoma and Lymphoma.
• Category V - 3 cases, among them one each was MNG, Follicular carcinoma and Follicular variant of Papillary carcinoma in histopathology.
• Category VI had 3 cases of Papillary carcinoma and had 100 % correlation in histopathology.
• The Sensitivity and specificity of The Bethesda system was 20% and 100 % respectively. The PPV - 100% and NPV - 91.1%.
CONCLUSION :
Further studies with larger sample size recommended to overcome the low sensitivity rate in the present study
Assessment on outcome of papaya fruit on premenstrual tension syndrome among adolescent girls in selected setting.
Premenstrual syndrome is medically defined as distressing physical and
psychological symptoms not caused by organic disease which appear before menstruation
regress during the menstruation, perhaps a hormone imbalance, due to lack of
progesterone, a poor diet and lack of exercise. Premenstrual tension syndrome is the
emotional tension, insomnia, depression, irritability associated with the premenstrual
week. Somatic sensations associated with the syndrome are bloating, cramping, tenderness
of the breasts, swelling of hands and feet, temporary weight gain. Premenstrual disorder is
a condition in which the symptoms of premenstrual syndrome are more severe and cause
significant functional impairment .It has been estimated that anywhere from 3 to 9% of
women suffer from this disorder (Woods, 2005).
In premenstrual syndrome, symptoms can be controlled to some extent by the
dietary manipulations. Studies suggest that a diet high in vitamin C, calcium and
magnesium was helpful in order to reduce the level of premenstrual tension syndrome. It is
advisable to take diet consisting of fruits which is rich in calcium, antioxidant, vitamin A
and minerals from one week prior to menstruation. Papaya fruit is an excellent source of
dietary fibre, folate, vitamin A, C and E.It also contains small amount of calcium, iron,
riboflavin, thiamine and niacin. It is also very rich in antioxidant nutrients flavanoids and
carotenes, very high in vitamin A and C & and also low in calorie.
Premenstrual syndrome is linked to other disorders associated with inadequate
calcium, iron, vitamins and minerals. Hence the researcher was interested to reduce the
level of premenstrual tension syndrome by providing papaya fruit for adolescent girls. The
aim of the study was to determine the outcome of papaya fruit on premenstrual tension
syndrome among adolescent girls in selected setting. A Quasi experimental design was
adopted. The study was conducted at selected government school, Arakonam.60
adolescent girls were selected.30 in experimental and 30 in control group. Adolescent girls
who fulfilled the inclusion criteria were selected by using non probability purposive
sampling technique.
The demographic variables were age in years, age at menarche, weight in
kilogram, body mass index and type of diet. The pretest and posttest level of PMTS was
determined by modified premenstrual tension syndrome scale.75 mg of papaya fruit was
provided by the researcher from the 5th day of last menstrual period in mid morning for 21
days. Data analysis was done by using descriptive and inferential statistics. The pretest and
posttest level of premenstrual tension syndrome were compared and found that in pretest
6(20%)had mild level of premenstrual tension syndrome,24(80%)had moderate level of
premenstrual tension syndrome ,none of them comes under severe level of premenstrual
tension syndrome and in post test 27(90%) had mild level of premenstrual tension
syndrome,3(10%) had moderate level of premenstrual tension syndrome, none of them
comes under the severe level of premenstrual tension syndrome.
Thus the study concludes that papaya fruit was effective to reduce the level of
premenstrual tension syndrome. The conceptual framework was based on modified
Weidenbach’s helping art nursing theory. The research hypothesis formulated for the
study was “there is a significant relationship between the premenstrual tension syndrome
and papaya fruit” .The outcome was proved in comparing the pretest and post test level of
premenstrual tension syndrome where the result showed p<0.05 level of significance. Thus
the research hypothesis was accepted. It was also found that papaya fruit have a role in
reducing PMTS. This is statistically proved that research hypothesis was accepted as
papaya fruit was effective to alleviate PMTS
Generalized Gingival Pyogenic Granuloma in a 11 Years Old Female – A Diagnostic Challenge
Aims: To include pyogenic granuloma as one of the differential diagnosis of generalized gingival enlargements.
Presentation of Case: In this article, we report a 11 years old female patient with generalized gingival enlargement, which on thorough clinical, histopathological and radiological examination concluded as a generalized gingival pyogenic granuloma.
Discussion: Pyogenic granuloma (PG), a non specific conditioned gingival enlargement is a common localized exaggerated reactive hyperplasia of connective tissue of the oral cavity or skin in response to local factors and chronic irritation. But PG presenting as a generalized gingival enlargement is very rare and uncommon. Only one case was reported on “Generalized gingival pyogenic granuloma” in 2011, showing its rarity. But in our case, in addition to generalized presentation of pyogenic granuloma, it was also associated with extensive alveolar bone loss, tooth mobility and root resorption.
Conclusion: Hence, although it is uncommon, pyogenic granuloma can also occur as a generalized gingival enlargement
Robust Image Watermarking Using QR Factorization In Wavelet Domain
A robust blind image watermarking algorithm in wavelet transform domain (WT) based on QR factorization, and quantization index modulation (QIM) technique is presented for legal protection of digital images. The host image is decomposed into wavelet subbands, and then the approximation subband is QR factorized. The secret watermark bit is embedded into the R vector in QR using QIM. The experimental results show that the proposed algorithm preserves the high perceptual quality. It also sustains against JPEG compression, and other image processing attacks. The comparison analysis demonstrates the proposed scheme has better performance in imperceptibility and robustness than the previously reported watermarking algorithms
Disk Resident Taxonomy Mining for Large Temporal Datasets
Mining patterns under constraints in large data is a significant task to advantage from the multiple uses of the patterns embedded in these data sets. It is obviously a difficult task because of the exponential growth of the search space. Extracting the patterns under various kinds of constraints in such type of data is a challenging research. First, a memory-based, efficient pattern-growth algorithm, Forest Mine, is proposed for mining frequent patterns for the data sets and then consolidating global frequent patterns. For dense data sets, Forest-mine is integrated with FP-Tree dynamically by detecting the swapping condition and constructing FP-trees for efficient mining. Such efforts ensure that forest mine is scalable in both large and medium sized databases and in both sparse and dense data sets
Rare Occurrence of Herpes Zoster of Trigeminal Nerve following Extraction of Tooth
Herpes Zoster also known as Shingles is an acute viral infection which is an extremely painful and incapacitating ailment. It results from the reactivation of the varicella zoster virus. The triggering factors for the onset of an attack of Herpes Zoster include some form of immunosuppression. The diagnosis of Herpes Zoster can be made on proper medical history and a thorough clinical examination. Here is the report of a male patient affected by Herpes Zoster infection which followed after extraction of a lower first molar
Temporomandibular Joint Pain
Temporomandibular joint (TMJ) is a synovial articulation between mandibular condyle and glenoid fossa in the temporal bone. Any structural and/or functional changes can affect the TMJ and related structures. Temporomandibular disorder (TMD) is a heterogeneous group of musculoskeletal disorders mainly characterised by regional pain in the facial and preauricular area and/or limitations/interference of jaw movement. TMD has multifactorial aetiology, which includes biology, and environmental social, emotional, and cognitive factors. TMD is more common orofacial pain condition and nondental origin. Factors associated with TMD include other pain condition, auto-immune disorder and psychiatric illness. The clinical conditions may present with limitation in opening and closing mouth, pain and articular noise. So this chapter mainly deals with the classification of TMJ disorder, diagnosis and management particularly TENS and ultrasound therapy for TMJ disorder
