Published: June 2020

Abstrak. Indonesia negara yang mayoritas penduduknya mengkonsumsi beras sebagai makanan pokok. Usaha untuk memenuhi kebutuhan beras di masadepan akan terus dihadapkan oleh berbagai kendala seperti berkurangnya luasan pertanian, keterbatasan lahan pertanian produktif dan adanya perubahan iklim (kekeringan) serta kendala-kendala lainnya. Namun memanfaatkan lahan suboptimal Ultisol, pemberian pupuk dan melakukan perakitan varietas unggul baru diharapkan dapat mendukung usaha tersebut. Ada sebanyak 84 pot percobaan diberikan perlakuan stress air selama 21 hari. Parameter percobaan terdiri dari pertumbuhan tanaman, hasil tanaman dan kekeringan. Hasil pengujian diperoleh bahwa galur Sanbei M8-1 memiliki tingkat toleransi kekeringan yang lebih baik dibandingkan dengan galur Sanbei lainnya dan varietas Inpari 42. Jenis pupuk berpengaruh terhadap tinggi tanaman, galur/varietas dan jenis pupuk berpengaruh terhadap panjang akar saat panen. Pada percobaan ini tidak terdapat interaksi yang nyata antara perlakuan galur/varietas dan jenis pupuk terhadap pertumbuhan, hasil tanaman padi dan kekeringan. Performance of Local Rice Mutants M8 and Fertilization of Water stress in Suboptimal LandsAbstract. Indonesia is a country where the majority of the population consume rice as the staple food. In the future, the efforts to fill the need of rice will be facing by various obstacles, such as the lack of agriculture area, the limitedness in agriculture productive land, climate change (drought), other obstacle. However, the efforts will be supported by utilizing the Ultisol suboptimal land, spreading the fertilizer, and assembling the new superior variety. There are 84 pots of subject test have treated for 21 days with water stress. The parameters consist of plant growth, productivity and water stress. The results found that galur Sanbei M8-1 has a better drought tolerance than other galur and Inpari 42 variety. Moreover, the fertilizers types not only affect the plant and galur/variety height but also affect the roots lenght. In the experiment, there is not interaction between galur/variety treatment and the fertilizer type toward the growth, productivity of paddy and water stress.

This study aims to determine the level of erosion hazard in palm oil plantations in Subulussalam City. The research method uses a descriptive method based on field observations and soil analysis in the laboratory. Soil erosion is calculated by using the formula of Universal Soil Loss Equation (USLE) which is invented by Wischmeir and Smith (1978). The USLE method observes several aspects such as erosivity, erodibility, length and slope factors, crop management factors and conservation actions. This research consists of several stages, namely, preparation, data collection, field implementation, laboratory analysis and data analysis. The results of the study showed that at the location of this study there were six units of land maps (SST) with a total area of 2437.83 hectares. The highest potential erosion was found in SPL 2 which was 6762.10 tons ha-1 th-1 and the lowest potential erosion was found in SPL 1 which was 172.01 tons ha-1 th-1. The highest actual erosion was found in SPL 2 which was 473.35 tons ha-1 th-1 and the lowest actual erosion was found in SPL 5 which was 9.58 tons ha-1 th-1. There are 3 classifications of the level of erosion hazard namely the level of light erosion hazard (R) in SPL 1, SPL 5, and SPL 6, the level of moderate erosion hazard (S) in SPL 3, and the level of severe erosion hazard (B) in SPL 2 and SPL 4.
Applying Multivariate and Univariate Analysis of Variance on Socioeconomic, Health, and Security Variables in Jordan

Published: June 2020

Many researchers have studied socioeconomic, health, and security variables in the developed countries; however, very few studies used multivariate analysis in developing countries. The current study contributes to the scarce literature about the determinants of the variance in socioeconomic, health, and security factors. Questions raised were whether the independent variables (IVs) of governorate and year impact the socioeconomic, health, and security dependent variables (DVs) in Jordan, whether the marginal mean of each DV in each governorate and in each year is significant, which governorates are similar in difference means of each DV, and whether these DVs vary. The main objectives were to determine the source of variances in DVs, collectively and separately, testing which governorates are similar and which diverge for each DV.
The research design was time series and cross-sectional analysis. The main hypotheses are that IVs affect DVs collectively and separately. We carried out Multivariate and univariate analyses of variance to test these hypotheses. The population of 12 governorates in Jordan and the available data of 15 years (2000–2015) accrued from several Jordanian statistical yearbooks. We investigated the effect of two factors of governorate and year on the four DVs of divorce, mortality, unemployment, and crime. We used the rate of divorce, mortality, and crime, and the percentage of unemployment in the analyses. We transformed all DVs to multivariate normal distribution. We calculated descriptive statistics for each DV in each governorate and each year. We provided visual and numerical inspection of how each DV changed over time in each governorate compared with DV change in other governorates.
Based on the multivariate analysis of variance, we found a significant effect in IVs on DVs with p < .001. Based on the univariate analysis, we found a significant effect of IVs on each DV with p < .001, except the effect of the year factor on unemployment, was not significant with p = .642. The grand and marginal means of each DV in each governorate and each year were significant based on a 95% confidence interval. Most governorates are not similar in DVs with p < .001.
We concluded that the two factors produce significant effects on DVs, collectively and separately. Based on these findings, the government can distribute its financial and physical resources to governorates more efficiently. By identifying the sources of variance that contribute to the variation in DVs, insights can help inform focused variation prevention efforts.

Published: June 2020

Estimation of a highly accurate model for liquid flow process industry and control of the liquid flow rate from experimental data is an important task for engineers due to its non linear characteristics. Efficient optimization techniques are essential to accomplish this task.In most of the process control industry flowrate depends upon a multiple number of parameters like sensor output,pipe diameter, liquid conductivity ,liquid viscosity & liquid density etc.In traditional optimization technique its very time consuming for manually control the parameters to obtain the optimial flowrate from the process.Hence the alternative approach , computational optimization process is utilized by using the different computational intelligence technique.In this paper three different selection of Genetic Algorithm is proposed & tested against the present liquid flow process.The proposed algorithm is developed based on the mimic genetic evolution of species that allow the consecutive generations in population to adopt their environment.Equations for Response Surface Methodology (RSM) and Analysis of Variance (ANOVA) are being used as non-linear models and these models are optimized using the proposed different selection of Genetic optimization techniques. It can be observed that the among these three different selection of Genetic Algorithm ,Rank selected GA is better than the other two selection (Tournament & Roulette wheel) in terms of the accuracy of final solutions, success rate, convergence speed, and stability.

Published: June 2020

The sparsity principle suggests that the number of effects that contribute significantly to the response variable of an experiment is small. It means that the researchers need an efficient selection procedure to identify those active effects. Most common procedures can be found in literature work by considering an effect as an individual entity so that selection process works on individual effect. Another principle we should consider in experimental data analysis is the heredity principle. This principle allows an interaction effect is included in the model only if the correspondence main effects are there in. This paper addresses the selection problem that takes into account the heredity principle as Yuan et al. (2007) did using least angle regression (LARS). Instead of selecting the effects individually, the proposed approach perform the selection process in groups. The advantage our proposed approach, using genetic algorithm, is on the opportunity to determine the number of desired effect, which the LARS approach cannot.
Decision Making: Rational Choice or Hyper-Rational Choice

Published: June 2020

In this paper, we provide an interpretation of the rationality in game theory in which player consider the profit or loss of the opponent in addition to personal profit at the game.‎ ‎‎The goal of a game analysis with two hyper-rationality players is to provide insight into real-world situations that are often more complex than a game with two rational players where the choices of strategy are only based on individual preferences. The hyper-rationality does not mean perfect rationality but an insight toward how human decision-makers behave in interactive decisions. ‎‎The findings of this research can help to enlarge our understanding of the psychological aspects of strategy choices in games and also provide an analysis of the decision-making process with cognitive economics approach at the same time.‎

Authors: Santiago Luiz Miguel , Simões José Augusto , Vale Martinha , De Faria Elleni , Ferreira Pedro Lopes , Rosendo Inês 
Published: June 2020

Introdução: A Medicina Centrada na Pessoa é um método e modelo de prática permitindo ganhos para o médico e o paciente, devendo a sua prática ser avaliada para fins de desenvolvimento profissional contínuo e educação médica continuada. O objectivo deste estudo foi construir, determinar a fiabilidade e a validade de um instrumento capaz de aferir a auto perceção genérica da prática médica segundo a medicina centrada na pessoa no ambiente de medicina geral e familiar.Material e Métodos: Uma primeira versão de um questionário segundo as quatro dimensões do método clínico centrado na pessoa foi revista por um grupo focal garantindo a validade de conteúdo. O questionário final engloba 22 itens, utilizando para resposta uma escala de Likert com quatro opções. A análise fatorial permitiu confirmar as dimensões definidas por Moira Stewart, tendo também sido determinada a consistência interna, a reprodutibilidade por teste-reteste e a correlação item-total. A aplicação online a uma amostra de 905 médicos de medicina geral e familiar permitiu testar as validades de constructo e de critério.Resultados: O instrumento de medição inclui quatro dimensões: (i) explorar a saúde, a doença e a experiência de doença, (ii) investir na relação médico-doente; (iii) procurar entendimento; e (iv) compreender a pessoa como um todo. A consistência interna foi demonstrada com um alfa de Cronbach global de 0,892, variando entre 0,783 a 0,844 para todas as dimensões. A reprodutibilidade teste-reteste obteve um valor de correlação intraclasse entre 0,678 e 1,000. As correlações item-total variaram entre 0,457 e 0,870. As mulheres médicas estão mais sensibilizadas do que os seus colegas no que respeita à procura de entendimento com o doente e os médicos mais novos são os mais sensíveis à abordagem da doença através da anamnese e à procura de entendimento com o doente. Os especialistas demonstraram ter mais cuidado com a anamnese e com o facto de encarar o doente como um todo, e os profissionais que trabalham numa unidade de Saúde Familiar são os que procuram um melhor entendimento com a pessoa. Por fim, a formação específica sobre medicina centrada na pessoa e sobre consulta em medicina centrada na pessoa demonstraram ter um impacto positivoem todas as dimensões da medicina centrada na pessoa e isso é reconhecido pelos próprios profissionais.Discussão: A avaliação da auto perceção de desempenhar medicina centrada na pessoa é agora possível.Conclusão: O presente questionário apresenta boa fiabilidade e validade permitindo ao médico verificar quais as principais insuficiências bem como desenvolver formação específica.

Published: June 2020

Introdução: Com o envelhecimento progressivo da população portuguesa, é fundamental que as condições de acessibilidade e segurança na via pública estejam adaptadas a este grupo etário. O objectivo deste estudo foi avaliar se o tempo atribuído à travessia de peões nas passadeiras semaforizadas entre o Hospital de Curry Cabral e os transportes públicos locais é suficiente para permitir a travessia dos idosos em segurança.Material e Métodos: Foram avaliados 100 doentes seguidos em consulta externa no Serviço de Medicina Física e de Reabilitação. Todos responderam a um questionário, à escala de confiança no equilíbrio específica da atividade e executaram o teste de marcha de 10 metros. Foram analisadas todas as passadeiras semaforizadas dos percursos de marcha entre o hospital e os transportes públicos locais, num total de 26 e calculada a velocidade de marcha necessária para realizar a travessia das passadeiras em segurança.Resultados: A média de idade dos doentes foi de 75 anos, sendo a maioria do género feminino (73%). Concluímos que todos os doentes conseguem atravessar em segurança 17 (65%) passadeiras, representando as restantes nove (35%) um obstáculo para a nossa amostra.Discussão: Se o valor de velocidade de marcha nas passadeiras estipulado na legislação para os cidadãos com mobilidade condicionada fosse devidamente aplicado, 99% da amostra teria conseguido atravessar as passadeiras em segurança.Conclusão: É fundamental que o valor de velocidade de marcha nas passadeiras estipulado na legislação seja aplicado, pois o seu incumprimento coloca em risco os utentes idosos do Hospital de Curry Cabral, aumentando a probabilidade de acidentes e o sentimento de insegurança na via pública.

Published: June 2020

Introdução: As encefalopatias epilépticas da infância constituem um grupo de patologias de início precoce e prognóstico neurológico reservado. O desenvolvimento das novas técnicas de estudo genético foi responsável pela identificação de novos genes implicados. Nos últimos anos, assistimos a uma revolução no seu paradigma diagnóstico. Contudo, actualmente não existem recomendações internacionais consensuais sobre a abordagem à investigação das encefalopatias epilépticas genéticas. Pretendemos discutir o conhecimento actual sobre a arquitectura genética das encefalopatias epilépticas infantis.Material e Métodos: Realizou-se uma revisão da literatura das encefalopatias epilépticas infantis genéticas e estudos utilizados no seu diagnóstico. Propomos uma abordagem sistematizada através de um algoritmo diagnóstico a utilizar na prática clínica.Resultados: Inicialmente deve-se determinar o fenótipo do doente com base no tipo de crises, padrão electroencefalográfico e neuroimagem. Nos doentes sem etiologia após resultados de ressonância magnética cranioencefálica, deve-se realizar estudo metabólico apropriado para o diagnóstico prioritário de doenças metabólicas tratáveis. A investigação de outras causas genéticas deve ser considerada, sobretudo perante características fenotípicas sugestivas. Primeiro deve-se realizar a análise de microarray cromossómico, principalmente se existirem alterações dismórficas ou polimalformativas. Se esta for negativa e/ou não existirem elementos físicos distintivos, o próximo passo deve ser realizar os painéis multigénicos ou sequenciação de exoma. Os estudos dirigidos do gene devem ser reservados para quando o fenótipo é indicativo de uma síndrome específica.Conclusão: A marcha diagnóstica das encefalopatias epilépticas tornou-se complexa com a expansão de conhecimentos genéticos. Este novo paradigma apresenta implicações terapêuticas, prognósticas e de aconselhamento familiar.

Published: June 2020

Antibiotic resistance is the major growing threat facing the pharmacological treatment of bacterial infections. Therefore, bioprospecting the medicinal plants could provide potential sources for antimicrobial agents. Mimusops, the biggest and widely distributed plant genus of family Sapotaceae, is used in traditional medicines due to its promising pharmacological activities. This study was conducted to elucidate the antimicrobial effect of three unexplored Mimusops spp. (M. kummel, M. laurifolia and M. zeyheri). Furthermore, the mechanisms underlying such antibacterial activity were studied. The Mimusops leaf extracts revealed significant antibacterial activities against the five tested bacterial strains with a maximum inhibition zone diameter of 22.0 mm against B. subtilis compared with standard antibiotic ciprofloxacin. The minimal inhibitory and bactericidal concentration values against tested Gram-positive and Gram-negative bacterial strains ranged from 3.15-12.5 µg/ml. However, weak antifungal effect was recorded against Candida albicans with MIC value ˃25 µg/ml. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay showed that M. caffra was the best antioxidant (IC50=14.75±0.028 µg/ml), while M. laurifolia was the least one (IC50=34.22±0.014 µg/ml). The phenolics in plant leaves extracts were identified and quantified by high performance liquid chromatography (HPLC) which revealed the presence of seven phenolic acids and four flavonoids. The abundant phenolic compounds were rutin (5.216±0.067 mg/g dried wt.) and gallic acid (0.296±0.068 mg/g) followed by myricetin (0.317±0.091 mg/g) then kaempferol (0.113±0.049 mg/g) as flavonoids. The antibacterial mechanism of M. laurifolia extract, as a representative species, induces ultrastructural changes in the model bacterium Staphylococcus aureus with cell wall and plasma membrane lysis as revealed by transmission electron microscopy. Overall, Mimusops species (M. laurifolia, M. kummel and M. zeyheri) are promising natural alternative sources for antimicrobial agents.

Abstract
Background: Laparoscopic approach is now a widespread technique used worldwide, but there are few recent studies on risk factors for parastomal hernia. Therefore, this study was performed to analyze the incidence of parastomal hernia in laparoscopic and open surgery in which a loop stoma was created and was intended to be temporary, and to determine risk factors for parastomal hernia formation. Associations between parastomal hernia and other stoma-related complications were also analyzed.Methods: A retrospective analysis of patient and surgical characteristics was performed in 153 consecutive patients who underwent a temporary diverting loop ileostomy or colostomy after surgery related to malignant diseases at our hospital from January to December 2016.Results: Parastomal hernia developed in 77 cases (50.3%), including 39 (25.5%) diagnosed by physical examination and 38 (24.8%) detected by CT alone. On multivariate analysis, a stoma not passing through the middle of the rectus abdominis muscle was the only independent risk factor for parastomal hernia formation (p=0.005) during the median follow-up of 245.0 days. When we analyzed the factors that were associated with a stoma not passing through the middle of the rectus abdominis muscle, the only independent factor associated with this misplacement of the stoma was a laparoscopic approach (p=0.012). An analysis of stoma-related complications showed that peristomal skin disorders were significantly associated with parastomal hernia (p=0.049).Conclusions: This study showed that a stoma that is not formed through the middle of the rectus abdominis muscle is a risk factor for parastomal hernia formation, and that a laparoscopic approach is associated with this risk factor. Moreover, parastomal hernia is significantly associated with peristomal skin disorders.
