Implementation of the Naïve Bayes Algorithm for Divorce Prediction at the Tais Religious Court

Divorce is the breaking up of a husband and wife relationship, because there is no match between the two. Divorce is basically the release of the bond between husband and wife. In Tais district, based on the Tais Religious Court Annual Report from 2017, 2018 and 2019 it was found that there was an increase in the divorce rate. Based on the divorce rate which continues to increase every year, it is necessary to have data in the form of data to determine the factors that influence divorce. The use of Naive Bayes is that this method only requires a small amount of training data (Training Data) to determine the parameter estimates needed in the prediction process. In this case, it is assumed that the presence or absence of a certain event from a group is not related to the presence or absence of other events. With a system to predict divorce, it can help users who want to know the prediction of divorce. Based on the tests that have been carried out using the Black Box Method, the results show that the functionality of the divorce data prediction application has run as expected and the application is able to display the prediction results of Divorce Lawsuit and Divorce Divorce

Sistem Pakar Diagnosa Gangguan Hiperaktif Pada Anak Dengan Metode Naive Bayes Berbasis Web

Disorder concentration attention or better known as ADHD (Attention Deficit Hyperactivity Disorder) is one of the main psychiatric problems that are often found in children. Hyperactive disorders are usually seen in children and as we get older the more difficult to deal with. There were 3 hyperactive disorders taken in this study namely hyperactivity, Impulsivity, Inattetion (Personality Problems). To help diagnose these hyperactive disorders, an expert system application is made to diagnose hyperactive disorders in children that can facilitate the public in diagnosing hyperactive disorders in children. Making this web-based expert system application uses the Naive Bayes method. The Naive Bayes method is a simple opportunity classification based on the application of the Bayes theorem with the assumption that between variables (independent) the presence or absence of a particular event from a group is not related to the presence or absence of other events. The final results are given in the form of a percentage of the diagnosis of hyperactivity in children.

How Prediction Markets Can Save Event Studies

This review paper articulates the relationship between prediction market data and event studies, with a special focus on applications in political economy. Event studies have been used to address a variety of political economy questions from the economic effects of party control of government to the importance of complex rules in congressional committees. However, the results of event studies are notoriously sensitive to both choices made by researchers and external events. Specifically, event studies will generally produce different results depending on three interrelated things: which event window is chosen, the prior probability assigned to an event at the beginning of the event window, and the presence or absence of other events during the event window. In this paper we show how each of these may bias the results of event studies, and how prediction markets can mitigate these biases.

Bilateral Posterior Ischemic Optic Neuropathy Associated With Use of Sildenafil

We report a case of sequential posterior ischemic optic neuropathy after the use of sildenafil. A 76-year-old man with a history of systemic hypertension, hyperlipidemia, and stroke presented to our clinic with the sudden onset of sequential visual loss in his eyes. His usual medications were 50 mg atenolol daily and 90 mg diltiazem daily for hypertension and 10 mg simvastatin daily for hyperlipidemia. In addition, he had started taking a Chinese “health product” 7 weeks earlier. His usual dose was one capsule once a day or one capsule every other day, but he had stopped it 20 days earlier until 2 days before presentation, when he consumed three capsules all at once one morning. Approximately 36 hours after ingesting the three capsules, he experienced sudden visual loss in the left eye. He awoke the next morning and discovered blurred vision in the right eye and presented to our clinic. He reported no pain or headache or any symptoms of systemic hypotension such as dizziness, cold sweats, or feeling faint. He admitted to habitually drinking approximately 500 mL of beer a day but did not smoke. He had been compliant with his antihypertensive medications. Toxicologic analysis revealed 32.22 mg sildenafil in each capsule of the Chinese health product. He had no light perception in either eye. Both pupils were dilated and unreactive to light. Intraocular pressures were normal, and apart from the presence of mild cataracts and cup-to-disc ratios of 0.8 bilaterally, anterior and posterior segments were normal including the retinas. Both optic discs appeared pink. Blood pressure throughout his subsequent 5-day stay in hospital averaged 130/80 mm Hg, ranging between 120/60 and 130/90 mm Hg. Complete blood count, erythrocyte sedimentation rate, and C-reactive protein, creatinine, VDRL, folate, and vitamin B12 levels were normal. Results of liver function testing were normal apart from decreased albumin (32 g/L; normal = 37-51 g/L) and elevated -glutamyltransferase (80 IU/L; normal = 11-63 IU/L). No mitochondrial DNA mutation at nucleotides 3460, 11778, or 14484 was found. Contrast-enhanced MRI scans with angiography of the brain and orbits was normal. Electroretinography was normal, and visual evoked potentials were absent. After 6 weeks, visual acuity improved to count fingers in the right eye and hand movements in the left eye. Both optic discs were pale. Nonarteritic anterior ischemic optic neuropathy has been reported to occur 30 minutes to 36 hours after ingestion of the phosphodiesterase-5 (PDE-5) inhibitor sildenafil (1,2), and a cause-and-effect relationship has been suggested.(3) We believe our patient suffered sequential nonarteritic posterior ischemic optic neuropathy (PION), which may occur in the setting of systemic vascular disease as well as systemic hypotension. Visual loss in our patient began approximately 36 hours after a relatively large dose (96.66 mg) of sildenafil. The short duration between the onset of visual loss in both eyes in the absence of other events that would have caused a drop in blood pressure, within a relatively short interval of taking the increased dose of sildenafil, suggests a possible role for that agent in the development of his visual loss. Diltiazem may have contributed by inhibiting cytochrome P450 3S4, the isoenzyme predominantly responsible for the metabolism of sildenafil (4) and prolonging the duration of action of sildenafil. To our knowledge, PION has not been reported in association with sildenafil. We postulate that a sildenafil-induced decrease in blood pressure (6), together with vasculopathic risk factors and antihypertensive therapy, contributed to its development.

The origin of laminated and massive anorthosite, Sept Iles layered intrusion, Québec, Canada

Well-laminated plagioclase-rich rocks (‘anorthosite’) occur as layers in mineralogically similar but massive rocks in the Sept Iles intrusion. Several phases of crystallization of poikilitic clinopyroxene have preserved the intermediate stages in the production of these rocks. Plagioclase nucleated and initially grew in random orientations in the stationary part of the boundary layer. There, in the absence of other events, crystallization produced the massive anorthosite. The laminated anorthosite may have been produced by episodic increases in the velocity of the magma adjacent to the boundarylayer induced by magmatic density-currents. Such currents would have caused the zone of simple shear of the boundary-layer to migrate outwards into the previously stationary part. This simple shear would then have rotated the existing plagioclase crystals, as well as crystals that nucleated at that time, towards the shear-plane. Some rocks show evidence of several periods of enhanced flow-velocities. The production of the lamination may have weakened the crystal-mush and enabled slumping to occur, producing folds and contorted layers. Finally, compaction liberated large quantities of intercumulus magma of which some was trapped as granophyric segregations and some escaped by overturing and churning the crystal-pile. Earlier-formed granophyric segregations and laminated layers were disrupted during this process to produce a range of more-complex rocks including igneous breccias.
