In this paper, a new method has been proposed for identifying anonymous fake reviews generated by click farmers in E-commerce and improves the identification rates. Anonymous fake reviews are different from the gunuine reviews. They could be distinguished based on the credibility of users, the average daily number of evaluations, the content similarity, and the degree of word overlapping. The proposed method takes into account these 5 features to calculate the fake reviews content by constructing multivariate linear regression model, Experiments show that this prelimilnary work performed well in identifying fake reviews in Chinese E-commerce website. The extracted features are also useful to identifying the fake reviews when the reviewer’s identification is not accessable.

The classification can be performed by using the decision tree approach. Previous researches on the classification using the decision tree have mostly been intended to classify text data. This paper was intended to introduce a classification application to the content-based image retrieval (CBIR) with multi-attributes by using a decision tree. The attributes used were the visual features of the image, i.e. : color moments (order 1, 2 and 3), image entropy, energy and homogeneity. K-means cluster algorithm was used to categorize each attribute. The result of categorized data was then built into a decision tree by using C4.5. To show the concept in application, this research built an application with main features, i.e.: cases data input, cases list, training process and testing process to do classification. The resulting tests of 150 rontgen data showed the training data classification’s truth value of 75.33% and testing data classification of 55.7%.

Paraquat (1, 1’-dimethyl-4, 4’-bipyridylium dichloride) is a highly toxic herbicide. Recently, Paraquat is still used widely in the plantations area, mainly in palm oil plantations. Paraquat application continuously can be increased Paraquat concentration and contaminated in soil and water. This study aimed was to analysis Paraquat exposure in environmental media water and soil, and the calculation of risk quotient of Paraquat in palm oil plantation. The study design of this research was a cross sectional with the laboratory examination Paraquat concentrations in soil and water. Soil and water samples taken by grab sampling with random composites. Water samples were taken from three sources in palm oil plantations area. Whereas soil samples were taken at a depth of 0-10 cm (top soil) and the number of soil samples as much as 5 samples. Furthermore, the risk quotient of Paraquat concentration in the water used in the palm oil plantation. The laboratory tests of Paraquat concentration were in water and soil with gas chromatography. The results of laboratory tests showed that Paraquat concentration in water samples were found between <0.005 to 0.01 mg/l and Paraquat concentration in soil samples were found between <0.005 to 0.08 ppm. The calculation of risk quotient was 0.058 mg/body weight/day. Although, the calculated of risk quotient showed less than one. Therefore, prior to use the water must be treatment first. While the recommended water to consumption as much as 2 liters/day for a 55 kg body weight to Indonesian workers.

Electroplating workers were exposed by particulate and fog of chromium from electrolysis process during work. Chromium is highly carcinogenic when inhaled.  Chromium can be reduced in the cells in the body. This process may generate Reactive Oxygen Species (ROS) causing lipid peroxidation and oxidative DNA damage. This research was aimed to analyse the influence of chromium to the levels of urinary 8-OHdG as an indicator to support early diagnosis of occupational disease. 66 electroplating workers in Tegal District were taken purposively as samples for this research. There were association between chromium level in urine, malondialdehyde (MDA) level, Body Mass Index, smoking habit, alcohol and supplement drink consumption and urinary 8-OHdG (p<0.05). There was not association between BMI and urinary 8-OHdG (p>0.05). Multivariate analysis using logistic regression showed the alcohol consumption had the most powerful influence to the level of urinary 8-OHdG. The levels of urinary 8-OHdG could be used as an indicator of oxidative DNA damage and early diagnosis of occupational disease among electroplating workers who were exposed by chromium.

Rapid-Acting Antidepressants and Underlying Mechanisms

10.11591/ijphs.v5i4.4828
Samuel E Wilson , Meta Chen , Hiren Darji
Loss of glial cells with resulting atrophy of the medial prefrontal cortex (mPFC) as well as the hippocampal area is demonstrated in depressed patients by brain imaging and postmortem studies. The mPFC is the master control of mood and emotional response. The hippocampus is part of the limbic system, the main function of which is to regulate emotions. The mPFC depends on the hippocampus for rapid learning and memory consolidation. Unlike monoamine reuptake inhibitor antidepressants, which take 6 to 8 weeks to exert their full effects, and with 30 - 40% unresponsive rate, ketamine acts rapidly, within a couple of hours, and has higher responsive rates. It suggests that in theory, due to its rapid effect, Ketamine could well serve as a bridging remedy to lower the rate of suicidal risk before Selective serotonin re-uptake inhibitors (SSRIs) reach their full effect for long-term depression management. Yet, ketamine has long been linked with abusive potential and possible neurotoxicity if used in large doses over a prolonged period. Even though there are no collected data to prove the associated adverse effects, awareness of this negative aspect of ketamine is sufficiently widespread to propel the psychiatric community to look for other rapidly acting antidepressant alternatives. Recent studies have shown that scopolamine, the Yueju pill, and magnesium are rapid-onset antidepressants that have mechanisms comparable to that of ketamine. These rapid-acting antidepressant agents promise to be effective and safer choices for depression management in the future, providing that further studies and investigations to produce a better and fuller understanding of their effects and limitations.

The purpose of the study was to evaluate the level of job satisfaction among the nurses of Makueni District Hospital. This was necessitated by the high nurse staff turnover from the facility and a myriad of complains from various departments. The study was a cross sectional descriptive survey involving about 50 nurses that was carried out between 15 and 19th July 2013. The study employed mixed method approach. Tests of significance were through use of Chi-square, Fishers exact test and logistic regression. The key results were that overall job satisfaction was low (36%). There were significant relationships between job satisfaction and cordial relationship with the nurse manager (c2 12.131 df 4 p=0.016<0.05. Logistic regression p=0.018<0.05). The plans to quit the hospital and work elsewhere indicates a relationship with job satisfaction (c2 12.749 df 4 p=0.013<0.05). The findings of this study suggest that there is no enabling working environment for the nurses and this could be a barrier to service delivery in the Hospital. These findings suggest that the Nurse Managers should build up effective relationship with the staff and other departments and should identify negative working conditions which affect staff and appropriately delegate authority to them.
