Published: May 2019

Background:

We performed a systematic review and meta-analysis of the literature to quantify the impact of patients with severe obesity (body mass index [BMI] > 35 kg/m2), those with morbid obesity (BMI > 40 kg/m2), and those with super-obesity (BMI > 50 kg/m2) on revision rates and outcome scores after primary total hip arthroplasty compared with non-obese patients (BMI < 25 kg/m2).

Methods:

Four electronic databases were reviewed (AMED, Embase, Ovid Healthstar, and MEDLINE) from their inception to August 2016. The search strategy used combined and/or truncated keywords, including hip replacement or arthroplasty and obesity, BMI, or any synonym of the latter in the title, abstract, or manuscript text. Abstracts and full text were reviewed by 3 pairs of reviewers to identify those assessing outcomes following primary total hip arthroplasty for different BMI categories. Outcomes evaluated were revisions (total, aseptic, and septic) and change in outcome scores (preoperative to postoperative).

Results:

The literature search identified 1,692 abstracts; 448 were included for the full-text review, and 33 were included in the meta-analysis. The morbidly obese and super-obese groups were at an increased risk for revision, especially for septic revisions, compared with the non-obese group. The severely obese group had risk ratios of 1.40 (95% confidence interval [CI], 0.97 to 2.02) for revision, 0.70 (95% CI, 0.45 to 1.10) for aseptic revision, and 3.17 (95% CI, 2.25 to 4.47) for septic revision. Morbidly obese patients had risk ratios of 2.01 (95% CI, 1.81 to 2.23) for revision, 1.40 (95% CI, 0.84 to 2.32) for aseptic revision, and 9.75 (95% CI, 3.58 to 26.59) for septic revision. Super-obese patients had risk ratios of 2.62 (95% CI, 1.68 to 4.07) for revision, 1.98 (95% CI, 0.80 to 4.94) for aseptic revision, and 7.22 (95% CI, 1.51 to 34.60) for septic revision. However, there was no significant difference (p > 0.05) in the standardized mean difference of functional outcome scores between the severely obese cohort (0.04 [95% CI, −0.02 to 0.10]), the morbidly obese cohort (0.19 [95% CI, −0.08 to 0.46]), and the super-obese cohort (−0.12 [95% CI, −0.57 to 0.33]).

Conclusions:

Severely obese patients, morbidly obese patients, and super-obese patients undergoing total hip arthroplasty should be counseled that, although they have comparable outcome score improvements compared with non-obese patients, they have significantly higher risks of all-cause and septic revision.

Acute Kidney Injury in Lower-Extremity Joint Arthroplasty
Authors: Rudy Michael D. , Ahuja Neera K.
Published: May 2019

» Acute kidney injury, defined as an increase in serum creatinine of 0.3 mg/dL or >50% of baseline or sustained oliguria with urine output of <0.5 mL/kg/hr for >6 hours, affects 2% to 15% of patients undergoing lower-extremity joint arthroplasty. Patients who develop acute kidney injury have an increased length of hospitalization and a greater cost of care, are less likely to be discharged home postoperatively, and have increased short-term and long-term mortality.

» Risk factors for acute kidney injury after lower-extremity joint arthroplasty include older age, male sex, obesity, diabetes, hypertension, congestive heart failure, and especially underlying chronic kidney disease.

» Consensus guidelines have not been updated to reflect recent research into the perioperative effects on angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs); most patients taking these medications chronically without systolic heart failure should omit the dose prior to the surgical procedure to reduce the risk of perioperative hypotension and acute kidney injury.

» In patients at an increased risk for acute kidney injury, efforts should be made when clinically appropriate to minimize exposure to potential nephrotoxins including nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase-2 (COX-2) inhibitors, intravenous computed tomography (CT) contrast, and antibiotics with higher rates of nephrotoxicity such as vancomycin and aminoglycosides.

» The initial evaluation for patients developing acute kidney injury after lower-extremity joint arthroplasty should include ruling out urinary obstruction, clinical volume status assessment, determining whether intraoperative or postoperative hypotension has occurred, urinalysis, and urine electrolyte studies.

O inglês necessário aos pilotos da “Esquadrilha da Fumaça”: quão específica pode ser a Língua para Fins Específicos?
Authors: De Carvalho e Silva Ana Lígia Barbosa
Published: May 2019

De fato, um curso de Línguas para Fins Específicos (LFE) direciona-se a um determinado propósito, e por isso deve se guiar por uma análise de necessidades. Este artigo tem por objetivo problematizar a especificidade do inglês necessário a um grupo de pilotos militares da Força Aérea Brasileira (FAB), o Esquadrão de Demonstração Aérea (EDA), ou “Esquadrilha da Fumaça”. Para tanto, realizamos uma revisão bibliográfica sobre o Inglês para Aviação e analisamos as situações de uso da língua pelo grupo. Os dados foram triangulados a partir de uma multiplicidade de participantes e procedimentos metodológicos, como entrevistas, grupos focais, observação e análise documental. Os resultados do estudo evidenciam que, paradoxalmente, a especificidade do inglês necessário ao EDA abarca até mesmo o chamado Inglês Geral, já que seus aviadores, além de pilotos, são oficiais militares que exercem, cumulativamente, funções administrativas, em solo, para representar a FAB e o Brasil no exterior.
As relações interconceitos da terminologia do domínio das certidões de casamento brasileiras: proposta de sistema conceitual
Authors: Curti-Contessoto Beatriz
Published: May 2019

Neste artigo, apresentamos um estudo acerca das relações conceituais mantidas entre os termos do domínio das certidões de casamento brasileiras, bem como nossa proposta de sistema conceitual dessa terminologia. Assim, buscamos responder, principalmente, aos seguintes questionamentos: sob qual formato esse sistema conceitual deveria ser apresentado? Em quais campos conceituais deveríamos organizar os termos? Que tipo de relação conceitual predomina entre as unidades terminológicas? Para respondermos a essas questões e realizarmos nossa investigação, fundamentamos nos pressupostos teóricos e metodológicos da Terminologia, sobretudo na Teoria Comunicativa da Terminologia de Cabré (1999) e nas contribuições de Barros (2004, 2007) com relação aos critérios de identificação e delimitação de termos, dentre outros. Esta pesquisa se deu sobre um corpus formado por 333 certidões de casamento brasileiras, a partir das quais delimitamos os 366 termos estudados.

Authors: Pérez Córdoba Alder Luis , Gomes Camacho Roberto
Published: May 2019

O objetivo deste trabalho é analisar, a partir da Teoria da Variação e Mudança (LABOV, [1972] 2008), a expressão ou não do pronome sujeito no espanhol falado no Caribe colombiano para determinar os grupos de fatores linguísticos que motivam esse uso variável. A amostra está constituída por gravações de 18 informantes para cada corpus sociolinguístico (Barranquilla, Cartagena e Valledupar), que compõem a variedade falada no caribe colombiano, coletados com base na metodologia do PRESEEA (MORENO, 1996). A análise quantitativa foi realizada mediante o uso do programa Goldvarb X (SANKOFF; TAGLIAMONTE; SMITH, 2005). Os resultados obtidos até aqui revelam que essa variedade integra a variedade conhecida por espanhol caribenho, de acordo com os índices percentuais de sujeito expresso, e mostram uma multiplicidade muito complexa de grupos de fatores em interação que contribuem para a expressão do pronome pessoal sujeito no dialeto analisado.

Published: May 2019

Neste trabalho, pretendemos propor uma discussão teórica sobre a noção de planos da linguagem na semiótica discursiva contemporânea. Utilizaremos como metodologia de análise aspectos teóricos da Historiografia Linguística, empreendida por pesquisadores como E. F. K. Koerner, P. Swiggers e C. Altman, para que haja um cotejo mais preciso do material que pretendemos apresentar. O córpus será composto dos estudos de autores que despontaram análises no âmbito da semiótica visual ou plástica, sendo eles: Lindekens, Floch e Thürlemann. Pressupomos que as análises apresentadas na contemporaneidade por Jacques Fontanille, Maria Giulia Dondero e Everardo Reyes-Garcia arrolam os debates empreendidos por Lindekens, Floch e Thürlemann e articulam os conceitos de substâncias e de formas do conteúdo e da expressão nas discussões contemporâneas, motivando o debate sobre a noção de planos da linguagem, principalmente ao desprender o plano da expressão do modelo teórico-metodológico até então consagrado na teoria.

Linguística, música e cognição humana: da representação estática à interação dinâmica
Authors: Penteado Siqueira Verônica
Published: May 2019

O objetivo deste trabalho é expor algumas das principais abordagens da ciência da cognição sobre as línguas naturais e a música, a fim de traçar um elo entre linguística, música e cognição humana, e, com isso, traçar o percurso realizado desde a pesquisa de Iniciação Científica até a seleção do objeto de estudo da pesquisa de mestrado. As abordagens serão revistas com o propósito de explorar tal objeto: a fala sincronizada (e a joint speech), vista a partir do paradigma dinâmico da cognição e da linguagem. Dessa maneira, procura-se defender a relevância da abordagem dinâmica para tratar da relação entre a música e a linguagem, bem como da própria natureza da fala, e apresentar a fala conjunta (joint speech) como um objeto de estudo empírico para investigar questões que vão além da fala e da linguagem.
Projeto ALIP (Amostra Linguística do Interior Paulista) e banco de dados Iboruna: 10 anos de contribuição com a descrição do português brasileiro
Authors: Gonçalves Sebastião Carlos Leite
Published: May 2019

Este artigo trata dos aspectos teórico-metodológicos da constituição do Banco de dados Iboruna, um banco de dados de médio porte, composto de 152 entrevistas sociolinguísticas (LABOV, 1972) e de 11 interações dialógicas, gravadas secretamente, em contextos de interação social livres (RONCARATI, 1996). Da experiência pioneira no Brasil em disponibilizar integralmente amostras de fala em áudio e as respectivas transcrições, resultaram, no período de uma década, importantes trabalhos de descrição sociofuncionalista de diferentes níveis de análise, do fonético-fonológico ao discursivopragmático. A conclusão mais evidente é a de que o avanço da pesquisa linguística baseada no uso da língua depende, cada vez mais, de bancos de dados sistematicamente organizados se tornarem disponíveis, principalmente se tais ferramentas contam com financiamento de recursos públicos.
Preparation of a selective flocculant for treatment of oily wastewater produced from polymer flooding and its flocculant mechanism
Authors: Wang Fei , Lü Hongmei , Wang Xiujun , Jing Bo , Duan Ming , Xiong Yan , Fang Shenwen
Published: May 2019

There are residual polymers in the oily wastewater produced from polymer flooding (OWPF); keeping the residual polymer in the water during the flocculation is meaningful and challenging. In this paper, a selective flocculant (denoted as PDC10) which can remove the oil while keeping partially hydrolyzed polyacrylamide (HPAM) in water was prepared by copolymerization of decyl two methyl vinylbenzyl ammonium chloride (C10MVBA) and dimethyl aminopropyl methacryamide (DMAPMA). By using oil removal and HPAM retention as evaluation indexes, the synthesis condition of PDC10 was optimized. The optimum PDC10 exhibited oil removal of 98.0% and HPAM retention of 80.5%. Its HPAM retention is much higher than that of a regular cationic flocculant. Measurements of zeta potential, interfacial tension, interfacial dilational modulus and a dual polarization interferometry (DPI) test were carried out for investigating the flocculation mechanism of PDC10. The mechanism of PDC10 was that it can bridge and flocculate oil droplets by electrostatic interaction and hydrophobic interaction. It also preferred to distribute at the interface, and its interaction with HPAM in bulk water was weak, which confirms its selective flocculation properties.
Adsorption and desorption of crystal violet and basic red 9 by multi-walled carbon nanotubes
Authors: Chen Xian , Chin Ching-Ju Monica
Published: May 2019

Batch adsorption and desorption of crystal violet (CV) and basic red 9 (BR9) on multi-walled carbon nanotubes (MWCNTs) were conducted. To investigate the possible mechanisms of adsorption/desorption hysteresis, oxidized MWCNTs (O-MWCNTs) with more oxygen-containing groups were obtained by oxidizing as-purchased MWCNTs (A-MWCNTs) using nitric acid. The adsorption kinetics could be described by the pseudo-second-order model, suggesting that chemical reactions are the rate-limiting steps. The adsorption isotherms were fitted well by the Langmuir model, which suggests that, in addition to π–π interactions, chemical reactions significantly affect the adsorption. The adsorption capacity decreased in the order of CV on A-MWCNTs, BR9 on A-MWCNTs, and BR9 on O-MWCNTs, possibly because the amidation between BR9 and the surface groups of MWCNTs results in steric hindrance, which limits the adsorption of BR9 to inner grooves between CNT bundles. Adsorption/desorption hysteresis was observed for BR9 but not for CV. It was found that the π–π interaction and molecular entrapment were not responsible for the adsorption/desorption hysteresis. The hysteresis might be caused by the irreversible amide bonds between BR9 and MWCNTs. The results indicate that the steric hindrance due to the three-dimensional structure of organic compounds plays an important role in both adsorption/desorption kinetics and equilibria.
Insights into the mechanism of methylene blue removed by novel and classic biochars
Authors: Chen Wei , Chen Fengting , Ji Bin , Zhu Lin , Song Hongjiao
Published: May 2019

The adsorption behavior and the underlying mechanism of methylene blue (MB) sorption on biochars prepared from different feedstocks at 500 °C were evaluated. The biochar feedstocks included Magnolia grandiflora Linn. leaves biochar (MBC), pomelo (Citrus grandis) peel biochar (PBC) and badam shell biochar (BBC). The results of characterizing and analyzing the samples showed that different biochars had different effects on the adsorption of MB. It could be found that MBC had the best adsorption effect on MB due to its largest average pore diameter of 5.55 nm determined by Brunauer-Emmett-Teller analysis. Under the optimal conditions, the maximum adsorption capacities of BBC, PBC and MBC were 29.7, 85.15 and 99.3 mg/g, respectively. The results showed that the amount of adsorption was affected by the pH value. The maximum adsorption capacity of MBC was 46.99 mg/g when it was at pH of 3, whereas for the same experimental conditions the maximum adsorption capacity of BBC and PBC was 25.29 mg/g at pH of 11 and 36.08 mg/g at pH of 7, respectively. Therefore, MBC was found to be a most efficient low-cost adsorbentl for dye wastewater treatment compared with BBC and PBC, and it had the best removal effect under acidic conditions.
Mainz Inventory of Microstressors (MIMIS): Development and ecological validation of a microstressor scale for adults (Preprint)
Authors: Chmitorz Andrea , Kurth Karolina , Mey Lara K. , Wenzel Mario , Lieb Klaus , Tüscher Oliver , Kubiak Thomas , Kalisch Raffael
Published: May 2019

BACKGROUND

Many of the existing scales for microstressor assessment do not differentiate between objective (i. e., observable) stressor events as opposed to stressful cognitions or concerns and often mix these items with other aspects of stress, such as perceived stressor severity, the evoked stress reaction or further consequences on health. This may result in spurious associations with other questionnaires measuring such constructs. Since most scales were de-veloped several decades ago, modern life stressors may not be represented.

OBJECTIVE

To develop a questionnaire that a) focuses on the retrospective assessment of objective microstressors over a one-week period and b) separates stressor occurrence from perceived stressor severity.

METHODS

Cross-sectional (N=109) and longitudinal studies (N=10 and N=70) were conduct-ed. In the longitudinal studies, Ecological Momentary Assessment (EMA) was used to com-pare stressor data, collected five times per day for 30 days, with retrospective reports (end-of-day, -week). Pearson correlations and multilevel-modelling were used in the analyses.

RESULTS

High correlations were found between the end-of-week, end-of-day and EMA data for microstressor occurrence (counts) (r ≥ .69 for comparisons per week, r ≥ .83 for cumulated data) and for mean perceived microstressor severity (r ≥ .74 for comparisons per week, r ≥ .85 for cumulated data). The end-of-week questionnaire predicted the EMA assessments suf-ficiently (counts: b= .03, 95% CI= .02 to .03, P<.001; severity: b= .67, 95% CI= .52 to .82, P<.001), the association did not change significantly over the period of four subsequent weeks.

CONCLUSIONS

Our results provide evidence for the ecological validity of the MIMIS questionnaire.

Objective User Engagement With Mental Health Apps: Systematic Search and Panel-Based Usage Analysis (Preprint)
Authors: Baumel Amit , Muench Frederick , Edan Stav , Kane John M
Published: May 2019

BACKGROUND

Understanding patterns of real-world usage of mental health apps is key to maximizing their potential to increase public self-management of care. Although developer-led studies have published results on the use of mental health apps in real-world settings, no study yet has systematically examined usage patterns of a large sample of mental health apps relying on independently collected data.

OBJECTIVE

Our aim is to present real-world objective data on user engagement with popular mental health apps.

METHODS

A systematic engine search was conducted using Google Play to identify Android apps with 10,000 installs or more targeting anxiety, depression, or emotional well-being. Coding of apps included primary incorporated techniques and mental health focus. Behavioral data on real-world usage were obtained from a panel that provides aggregated nonpersonal information on user engagement with mobile apps.

RESULTS

In total, 93 apps met the inclusion criteria (installs: median 100,000, IQR 90,000). The median percentage of daily active users (open rate) was 4.0% (IQR 4.7%) with a difference between trackers (median 6.3%, IQR 10.2%) and peer-support apps (median 17.0%) versus breathing exercise apps (median 1.6%, IQR 1.6%; all z≥3.42, all P<.001). Among active users, daily minutes of use were significantly higher for mindfulness/meditation (median 21.47, IQR 15.00) and peer support (median 35.08, n=2) apps than for apps incorporating other techniques (tracker, breathing exercise, psychoeducation: medians range 3.53-8.32; all z≥2.11, all P<.05). The medians of app 15-day and 30-day retention rates were 3.9% (IQR 10.3%) and 3.3% (IQR 6.2%), respectively. On day 30, peer support (median 8.9%, n=2), mindfulness/meditation (median 4.7%, IQR 6.2%), and tracker apps (median 6.1%, IQR 20.4%) had significantly higher retention rates than breathing exercise apps (median 0.0%, IQR 0.0%; all z≥2.18, all P≤.04). The pattern of daily use presented a descriptive peak toward the evening for apps incorporating most techniques (tracker, psychoeducation, and peer support) except mindfulness/meditation, which exhibited two peaks (morning and night).

CONCLUSIONS

Although the number of app installs and daily active minutes of use may seem high, only a small portion of users actually used the apps for a long period of time. More studies using different datasets are needed to understand this phenomenon and the ways in which users self-manage their condition in real-world settings.
Classification of Human Weight Based on Image
Authors: 'Uyun Shofwatul , Efendi Toni
Published: May 2019

Classification of human weight can be determined by body mass index. The body mass index can be calculated by dividing the height by the square of the body weight. According to researchers, this is less practical, so it needs to make a tool that can be used to determine ideal body weight more practically. One way is to use an Android smartphone camera. The camera is used to capture the image of the human body. Then the image is processed by using digital image processing and by using certain algorithms, so it may conclude the person's ideal weight category. The data used in this study are human photos, body weight and height. There are four stages to determine the weight and height based on the image. First, performing an analysis of the calculation of the derived formulas. Second, analyzing the edge detection algorithm. Third, conducting unit convertion, and fourth, proposing several algorithms to calculate the height and weight used to determine the ideal body weight. The results of the evaluation show that Algorithm C (measuring the width of an object starting with the height of the image adjusting half of the height of the object in the image) is the best algorithm with deviation value of 1.85% of the height and 8.87% of the weight, while the system accuracy rate in determining the ideal body weight has reached 78.7%.

Text Detection In Indonesian Identity Card Based On Maximally Stable Extremal Regions
Authors: Purba Angga Maulana , Harjoko Agus , Wibowo Mohammad Edi
Published: May 2019

Most of Indonesian organizations either it is government or non government sometime required their member to provide their identity card (E-KTP) as legal document collection in their database. This collection of image usually being used as manual verification method. These document images acquired by each person with their own device, there are variations of angles they are used to acquire the image. This situation created problems in text recognition by OCR softwares especially in text detection part, orientation and noise will affect their accuracy. These cases making the text detection more complex and cannot be solved by simple vertical projection profile of black pixels.  This research proposed a method to improve text detection in identity document by fixing the orientation first, then using MSER regions to form text region. We fix the orientation using the line that made by Progressive Probabilistic Hough Transform. Then we used MSER to obtain all candidate regions and Horizontal RLSA acts as connector between those candidate. The orientation fixing strategy reach average of margin error 0.377o (in 360o system) and the text detection method reach 84.49% accuracy in best condition.

Salak is a seasonal fruit that has high export value. The success of salak fruit exported is influence by selection process, but there is still a problem in it. The selection of salak still done manually and potentially misclassified. Research to automate the selection of salak fruit has been done before. The process of selection this salak fruits used convolutional neural network (CNN) based on image of salak fruits. The resulting of accuracy value from previous research is 70.7% for four class classification model and 81.45% for two class classification model. This research was conducted to increase accuracy value the classification of salak exported based on previous research. Accuracy improvement by changing the noise removal process to produce a better image. The changing also occur in the CNN architecture that layer convolution is more deep and with additional parameters such as Stride, Zero Padding, and Adam Optimizer. This change hopefully can increase the accuracy value of the salak classification. The results showed an accuracy value increased 22.72% from 70.70% to 93.42% for the category of four classes CNN models and increased 13,29% from 81.45% to 94.74% for category two classes.

This paper compares two different method in human fall detection system namely motion history image and approximated ellipse. Research has been done in small studio with 4 CCTV camera as video data recorder, whereas video data are processed using MATLAB software. The experiment was carried out using three object’s fall direction and two type of falling movement. The fall direction is consist of front, side, and back fall. Whereas the falling movement is consist of direct and indirect fall movement. Meanwhile, the object’s initial position is standing and size of captured object is constant. The result is motion history image has accuracy 74.26% for direct falling movement, and 75.69% for indirect falling movement. Whereas approximated ellipse has accuracy 56.85% for direct falling movement, and 61.81% for indirect falling movement. Therefore, motion history image is better than approximated ellipse in human fall detection system.

Handwritten characters are difficult to be recognized by machine because people had various own writing style. This research recognizes handwritten character pattern of numbers and alphabet using K-Nearest Neighbour (KNN) algorithm. Handwritten recognition process is worked by preprocessing handwritten image, segmentation to obtain separate single characters, feature extraction, and classification. Features extraction is done by utilizing Zone method that will be used for classification by splitting this features data to training data and testing data. Training data from extracted features reduced by K-Support Vector Nearest Neighbor (K-SVNN) and for recognizing handwritten pattern from testing data, we used K-Nearest Neighbor (KNN). Testing result shows that reducing training data using K-SVNN able to improve handwritten character recognition accuracy.

Wireless Sensor Network (WSN) is a wireless network consisting of a group of nodes scattered in a certain area. Each node has the ability to gather data around it and communicate with other nodes. In WSN, energy efficiency is important to maintain the lifetime of a network. A WSN consisting of several clusters and having a Cluster Head (CH) in each cluster requires a CH change mechanism in each cluster so that the network lifetime is longer.The LEACH algorithm is implemented on a system consisting of 9 sensor nodes and 1 sink node. Each sensor node monitors the temperature and humidity of the surrounding air. System testing is done by varying the number of data snippets per CH selection process in each LEACH cycle. Based on the results of testing, the application of the LEACH algorithm can increase network lifetime. The LEACH algorithm with 70 data snippets is an optimal state that results in a network lifetime of 7,387 seconds, whereas with the same number of data snippets when using a non-LEACH algorithm the network lifetime can only reach 5,565 seconds.

Diversity of macrofungi is widely studied because of its role as decomposer, and highly reported of its potentially using for foods, agricultures, medicinal purposes, and bioremediation. This study was carried out to consider sampling methods for macrofungi exploration especially in Turgo tropical forest ecosystem. There were two sampling method models which adequately bring our macrofungi collection to have valid data. The first is adaptive sampling which includes fixed-size plots where prior we decided how many tracks, plots, or what size to examine at each site to help keeping our focus on track. By having a fixed plot, we allowed ourselves to find our macrofungi and work on the identification process thoroughly without racing against the time as much. Then we can obtain frequency, distribution, density and others ecological quantitative data by sampling plots. Another way, we can choose opportunistic sampling, we mean carefully walking on through chosen site as study area and collecting conspicuous sporocarp of macrofungi. This method needs no plots and does not produce any quantitative data but looking for many more diversity on macrofungi. The way of sampling, depends on the duration of observation and the purposes of the research. According to the consideration result, we concluded to choose the adaptive sampling method to explore the macrofungi in Turgo tropical forest ecosystem.

A lot of the views of practitioners outside of Bali looked at the ceremony as one of the causes of poverty. It is seen from the portion of income that must be spent for various ceremonies to be performed by the Balinese Hindu community. This study aimed to answer the fundamental question, whether it is the customs and cultures led to affect Hindu community income in Bali? The data used is primary data from 350 Hindu households listed as poor households in Bali using depth interview survey method. Religion can play a role in overcoming poverty. Religion is not only a moral conscience that reminds the community will give generously to the poor but also to see the poor as human beings. The opinion says that the religious activities and custom made by Balinese Hindu communities causes increased poverty seems supported by the magnitude of the data portion of the expenditures for this activity. In Balinese Hindu communities, family income will be issued again and consumption expenditure shaped yajna. The analysis shows if traditional rituals and Balinese Hindu religious tend to have positive influence, good for people's income and the level of happiness. Therefore, it is not appropriate if the customs and religion are said to have made the Balinese Hindu community becomes poorer. This result also shows a shift in the understanding of religion in Balinese Hindu community. Religiosity someone then be interpreted by the implementation of the ritual in the form of upakara (yadnya) and the implementation of ethics in public life (susila).
