Review of Data Mining Techniques for Churn Prediction in Telecom

Telecommunication sector generates a huge amount of data due to increasing number of subscribers, rapidly renewable technologies; data based applications and other value added service. This data can be usefully mined for churn analysis and prediction. Significant research had been undertaken by researchers worldwide to understand the data mining practices that can be used for predicting customer churn. This paper provides a review of around 100 recent journal articles starting from year 2000 to present the various data mining techniques used in multiple customer based churn models. It then summarizes the existing telecom literature by highlighting the sample size used, churn variables employed and the findings of different DM techniques. Finally, we list the most popular techniques for churn prediction in telecom as decision trees, regression analysis and clustering, thereby providing a roadmap to new researchers to build upon novel churn management models

Aphrodisiac activity of vanari gutika formulated using milk obtained from jersey cow (Bos taurus), indigenous cow (Bos indicus) and buffalo (Bubalus bubalis)

585-591Erectile dysfunction (ED) is a condition characterized by the inability to develop or maintain erection of the penis. Ayurveda recommends vanari gutika, prepared from Mucuna pruriens as one of the products suggested for the management of sexual dysfunction. We were interested to validate and compare aphrodisiac potential of vanari gutika formulated, as per the principles of Ayurveda, using milk obtained from jersey cow (Bos taurus), indigenous cow (Bos indicus) and buffalo (Bubalus bubalis). In order to assess the aphrodisiac activity, Swiss Albino mice were used as experimental subjects (n = 6 animals per group) with oral administration of aforesaid three formulations of vanari gutika with different doses i.e., 8.56 mg/mL, 17.14 mg/mL and compared with standard sildenafil citrate (5 mg/kg) and vehicle (milk+ghee) for 7 consecutive days.  Animals were observed for mating behavior. Hormonal analysis, sperm count and histopathological studies were carried out to confirm physiological changes. The study exhibit marked changes in sexual behavior. Vanari gutika formulated using milk from indigenous cow at higher dose (17.14 mg/mL) showed significant increase in mounting frequency, hormone levels, sperm count and histopathology which revealed the ruptured seminiferous tubules. These investigations confirmed significant intensification of sexual activities in experimental animals

Comparative Evaluation of the Complementary and Alternative Medicine Therapy and Conventional Therapy Use for Musculoskeletal Disorders Management and Its Association with Job Satisfaction among Dentists of West India

ABSTRACTMusculoskeletal problems have become a significant issue in the profession of dentistry. There are currently no recommended effective disease-preventing and modifying remedies. High prevalence rates for musculoskeletal disorders (MSDs) among dentists have been reported in the literature. Complementary and alternative medicine can be helpful in managing and preventing the MSDs. The purpose of this study was to determine if dentists in the western part of India are using complementary and alternative medicine therapies for MSDs, and also to find if those who use complementary and alternative medicine therapies have greater job/career satisfaction compared to conventional therapy (CT) users. Dentists of western India registered under the Dental Council of India (N=2166) were recruited for the study. Data were analyzed using univariate and bivariate analyses and logistic regression. A response rate of 73% (n=1581) was obtained, of which 79% (n=1249) was suffering from MSDs. The use of complementary and alternative medicine or CT was reported by 90% (n=1124) of dentists with MSDs. Dentists using complementary and alternative medicine reported greater health (P<0.001) and carrier satisfaction (P<0.001) and were able to work as many hours they wanted (P<0.001) compared to CT users. Complementary and alternative medicine therapies may improve the quality of life and enhance job satisfaction for a dentist who suffers from MSDs

Antioxidant phenolic compounds from seeds of Hordeum vulgare Linn. ameliorates diabetic nephropathy in streptozotocin-induced diabetic rats

Objective: To examine the effects of hydroalcoholic extract and fractions of Hordeum vulgare Linn. (H. vulgare, Da Mai) on streptozotocin (STZ)-induced diabetic nephropathy in Sprague–Dawley rat models. Methods: The study involved preliminary phytochemical screening of extract and fractions, estimation of secondary metabolites, chromatographic studies using high performance liquid chromatography (HPLC), antioxidant potential using 1, 1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide radical scavenging and reducing power methods along with the determination of potential against diabetic nephropathy in STZ-induced rat models. Results: The phytochemical evaluation of the hydroalcoholic extract of H. vulgare and fractions revealed the presence of various phytoconstituents such as alkaloids, saponins, tannins, flavonoids, and glycosides. The chromatographic analysis indicated the peak complementing marker compound epicatechin and significant antioxidant activity in the extract and aqueous fraction. STZ-induced rats showed abnormal levels of serum albumin, creatinine, total cholesterol, blood urea nitrogen (BUN), and triglycerides, and urine albumin and creatinine, which returned to normal after 8 weeks of treatment with hydroalcoholic extract (400 mg/kg) and aqueous fraction (50 mg/kg) of H. vulgare. Conclusion: Hydroalcoholic extract (400 mg/kg) and aqueous fraction (50 mg/kg) of H. vulgare have significant antioxidant potential and positive effects on diabetic nephropathy. The fractionation and optimization increase the concentration of polyphenols in aqueous extract, causing a decrease in the dose required for effects against diabetic nephropathy

A Review Paper: Smart Train System Using IOT

This project describes the design, implementation and deployment of wireless train crowd and resource management system. The proposed solution can provide further energy efficient automated appliances to conserve energy. This is beneficial for commuter in the developing cities where there is mass population. The Internet of Things (IOT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction
