Published: November 2017

ABSTRACT The objective of this study was to evaluate the physiological characteristics and yield of ‘Pérola’ pineapple subjected to irrigation with saline water in the semi-arid region of Bahia. The experiment was conducted in randomized blocks with five treatments, represented by irrigation depths: 100% ETc, using water with electrical conductivity (ECw) of 0.75 dS m-1, and 50, 75, 100 and 125% ETc, using water with ECw of 3.6 dS m-1. The experiment used a drip irrigation system and pressure-compensating emitters with a discharge of 8 L h-1. In the physiographic conditions of Guanambi-BA, pineapple has limitations of the physiological characteristics of chlorophyll fluorescence and chlorophyll index, under irrigation with both saline water and better-quality water. The irrigation depth corresponding to 100% ETc using water with ECw levels of 0.75 and 3.6 dS m-1 led to the best yields.

ABSTRACT The use of saline water for irrigation causes severe restriction to nutritional balance, growth and production in many crops due to the effect of salts on plant and soil. The objective of this study was to investigate the response of melon (Cucumis melo L.) cultivars to various levels of irrigation water salinity on yield and fruit quality. A field experiment was conducted in a split-plot randomized block design with four replicates. The factors were five levels of irrigation water salinity (0.54, 1.48, 2.02, 3.03 and 3.90 dS m-1) in the plots and five melon cultivars (C1 - Sancho - Pele de sapo; C2 - Medellín - Pele de sapo; C3 - Mandacaru - Canary; C4 - Néctar - Galia; C5 - Sedna - Cantaloupe) in the sub-plots. According to the results, among the five genotypes studied, Sancho was the most salt-tolerant genotype, followed by Mandacaru, Medellín, Sedna and Néctar. Since irrigation water salinity did not influence the mean fruit weight, the reduction in the number of fruits was the main cause of yield reduction of the melon crop under high salinity water. The contents of total soluble solids increased under high salinity level.

Published: November 2017

Abstract Objective: Identify the route of birth delivery preferred by mothers and their motivations. Method: Cross-sectional study with 361 mothers from a university hospital. Data were obtained using a structured questionnaire from February to April 2013. Descriptive analysis was performed and the Chi-square test was used to verify association among the variables. Results: 77.6% of the women preferred vaginal delivery and the reason reported by 81.8% of them was easier recovery postpartum; 20.5% believed they took part in the decision-making concerning the type of delivery; 64.5% believed the type of delivery they experienced did not involve risk for themselves, while 21.9% believed it involved risk for the newborn. Statistical association was found between number of deliveries and type of previous delivery with the preferred route of delivery. Conclusion: Women did not have adequate knowledge regarding the risks and benefits of different types of delivery and for this reason were not empowered to exert their autonomy in regard to this decision.
ESCOLA PÚBLICA E LIBERALISMO NO BRASIL IMPERIAL: CONSTRUÇÃO DO ESTADO E ABANDONO DA NAÇÃO
Authors: Paula Dalvit Greiner de , Nogueira Vera Lúcia
Published: November 2017

Resumo O presente artigo discute o direito à educação de nosso primeiro legislador constitucional em 1824 que confere à Constituição do Império um caráter liberal. Assim, analisamos nossa primeira Constituição atentando para aqueles artigos e parágrafos que professam os direitos do cidadão identificando os direitos sociais, principalmente o direito à educação. Nessa análise, buscamos compreender como o liberalismo se apresenta no Brasil tentando incluir o país num sistema capitalista mundial negando o que havia de mais essencial do sistema, restringindo a competição ao criar dois patamares de cidadania, garantindo às elites todos os seus direitos e negando aos demais aqueles direitos mais essenciais para a consolidação do povo e da nação. Dessa forma, o legislador priorizou a formação e consolidação do Estado por intermédio de suas instituições deixando de lado a nação que o constituiria negando-lhe um dos seus principais direitos: a educação.
A MODA E AS MULHERES: AS PRÁTICAS DE COSTURA E O TRABALHO FEMININO NO BRASIL NOS ANOS 1950 E 1960

Published: November 2017

Resumo A construção dos aprendizados femininos com os tecidos, linhas e máquinas de costura, é analisada neste texto por meio das informações disseminadas por dois gêneros textuais diversos na transmissão de conhecimentos. O primeiro é o curso de corte e costura intitulado Método Vogue associado à Escola de Corte e Costura São Paulo e de autoria de Antonio Campagnolli, que mesmo com lacunas documentais sobre a totalidade de publicações, está no volume analisado em sua décima nona edição. Este material didático instrumentalizou milhares de mulheres à prática do corte e costura com seus volumes de cursos por correspondência que, juntamente ao Instituto Universal Brasileiro, dinamizou o ensino com a sua propagação ao interior do país por meio dos Correios. O segundo é Jornal das Moças, uma revista carioca produzida pela Editora Jornal das Moças Ltda. Um periódico semanal circulado entre os anos de 1914 a 1961 e que em suas páginas jovens e senhoras encontravam orientações sobre moda, beleza, costura, casa, culinária e cuidados com os filhos. Ambas as fontes são suportes na compreensão da relação feminina com a prática de corte e costura e neste intuito circunscrevemos a análise aos anos 1950 e 1960, pelos investimentos presentes neste período na divulgação do ensino desse ofício. Com o objetivo de compreender as concepções que nesse período relacionaram o ensino do corte e costura às mulheres, o texto é dividido em três partes que exploram o corte e costura associado à imagem feminina, sua difusão midiática e sua contribuição para a educação e para o trabalho feminino profissional e doméstico.

Authors: Berdieva Nigina N. , Shapovalova Eleonora V. , Riks Inna A.
Published: November 2017

Introduction. Until the 2000s, in diseases leading to corneal blindness, it was expediently to perform subtotal keratoplasty in order to provide an organ-sparing effect and restore visual functions. Such procedures were not widely spread due to a great number of problems; they were performed with extended depressurization of the eye, and had a high risk of intraoperative complications. Nowadays, many ophthalmologists face the remote consequences of subtotal keratoplasty.

Aim. The purpose is to evaluate the transplant after subtotal penetrating keratoplasty (SPK) and visual functions in the remote postoperative period.

Materials and methods. We have examined 14 patients (14 eyes), aged from 28 to 81 years, at 6-10 years after SPK. Visual acuity (VA) testing, autorefractometry and confocal microscopy (Confoscan 4) were performed.

Results. According to visual acuity testing results, patients were divided into 3 groups: 1st group with high VA (more than 0.2 in 7.2% of patients), 2nd group with medium VA (from 0.2 to 0.005 in 21.4% of patients), and 3rd low VA (less than 0.005 in 71.4% of patients). Before the SKP, VA was 0.004-0.7. After the SKP, the indices varied from light sensation with correct light projection to 1.0. High rate was in 21.5%, medium in 35.7%, low in 42.8% of cases. According to autorefractometry data, the cylindrical component was in average 6.5 3.0. Most often, astigmatism was revealed in the low (up to 3) and high degree (more than 6). According to confocal microscopy data, the average density of endothelial cells was 1700 50 cells/mm2.

Conclusion. More than a half of patients has preserved good visual functions and a transparent transplant at 6-10 years after the SKP, and this significantly improves the quality of patients life.

Published: November 2017

The article reviews the literature on the classification of endothelial-epithelial dystrophy (EED) of the cornea. The description of endothelial structure, etiology and pathogenesis of the corneal EED are described. Based on own multiple observations and modern methods of corneal tissue imaging, a new modification of the EED classification by V.V. Volkov and M.M. Dronov was created and is presented in the article. This classification makes it possible to more accurately determine the etiopathogenesis of changes in corneal layers and to choose a most rational and effective treatment method.

Authors: Safonova Tatyana N. , Gladkova Olga V. , Novikov Ivan A. , Boev Vasil I.
Published: November 2017

The aim is to improve the treatment method of severe keratoconjunctivitis sicca (KCS) forms using designed soft contact lenses (SCL).

Material and methods. An original SCL of silicone hydrogel material with individual optical power, consisting of a non-through depot filled with 0.05% Cyclosporin A (CyA) was designed. The therapeutic CyA saturated SCL was used in 5 patients (1 male and 4 females; 7 eyes) aged from 34 to 66 years, with severe KCS, who were constantly wearing them for 7-14 days. Patients additionally instilled hyaluronic acid containing non-preserved artificial tears up to 6 times a day. Standard ophthalmic examination, Schirmer test, tear break-up-time test, tests using vital dyes (assessed using the Oxford scale), tear osmolarity measurements (TearLab System, USA), tear pH measurement by a highly sensitive litmus test, conjunctival culture, measurement of the interpalpebral fissure width were carried out, the ocular surface disease index (OSDI) was determined. Treatment results were assessed in 1 week, 1 month, and 3 months since the SCL wear start.

Results. The use of therapeutic CyA saturated SCL allows to achieve complete corneal epithelization, and helps to reduce inflammation within the time from 1 week up to 1 month, significantly reducing the treatment timeframe of severe forms of KSC in comparison to standard therapy.

Conclusion.The developed treatment method for severe forms of the KCS consists in using specifically designed therapeutic SCL which provides an even CyA 0.05% release on the ocular surface, while instilling non-preserved artificial tears. Preliminary results show a high efficacy of this method in terms of reducing corneal epithelization time up to 1 week-1 month and resolving inflammation on the ocular surface.

Objective: In the evaluation of children dragged to crime aged between 13 and 15 years-old, risk factors should be examined in detail. In this study, the primary goal of is evaluation of sociodemographic and clinical characteristics of juvenile offenders and the secondary goal is to examine the features that the clinician considers while setting up reports.
Materials and Methods: Medical records of children dragged to crime aged between 13 and 15 years old were evaluated retrospectively. The sociodemographic characteristics of children and their parents’ crime type, crime story, family crime story and report result were included in the study.
Results: The majority of cases (87.1%) were males. 31.7% of the cases left school. 55.4% were able to perceive the legal meaning and outcome of the crime and to direct their behavior. 43.6% had a mental disorder and the most common disorder was attention deficit hyperactivity disorder. The most common type of crime was wounding. 32.7% had repetitive crime stories. Both in the group that perceives the legal meanings and consequences of the crime and in the group of repetitive crime revealed statistically significant school failure, parental consanguinity, crime story in first-degree relative, cigarette/alcohol/substance abuse, and mental illness. Beck depression and trait anxiety scale (STAI-2) scores were higher in the group of repetitive crime. Theft (p=0.012) and battery crimes (p=0.046) tended to repeat more often.
Discussion: Prominent risk factors in both criminal responsibility and repetitive crime groups are school failure, parental consanguinity, crime stories in relatives, cigarette/alcohol/substance abuse, and mental disorders. Although it is known that these risk factors may be a genetic ground, it is striking that many of them are features that can be prevented by protective and supportive studies. Social projects need to be developed for the children dragged to crime.

Objective: In the field of forensic science, one of the most noteworthy topics about identical twins is hand writing.
In this study; It is aimed to determine the degree of similarity of the handwritings of the identical twins and to evaluate the effect of the genetic similarities in terms of examination of the judicial documents.
Materials and Methods: In our study; “Atatürk’ün Gençliğe Hitabesi”- “Atatürk’s Speech to Youth” is printed on 100 voluntary adults. Letters “a, b, d, g, m, r, ş, u, v, y, z” were examined with the aid of a magnifying glass and ruler.
Results: There were no statistically significant differences in the similarity rates of the handwritten characters with the variables analyzed (gender of twins, age, occupation of the same profession, same level of education, residence time in the same household, frequency of use of writing, (p>0.05). The letter “d” (56%) used by 50 twin pairs was used as the most similar letter, and the letter “m” (14%) was used as the least similar letter. It has been found that the handwritings of female couples show more similarity than male couples. The similarity rates of female twins in their handwriting were 90.9% maximum, minimum 0%; The similarity ratios of the male twins to the handwriting maximum: 54.54%, minimum 0%. Conclusion: Even though the handwriting is highly similar in our work, we have achieved results that support the scientific truth that the two handwriting cannot be quite similar. The results are important in terms of diagnostic features in the identification of handwritings.

Authors: Efeoğlu Özşeker Pınar , Dağlıoğlu Nebile
Published: November 2017

The use of alternative biological samples has increased with the development of sensitive and selective analytical techniques in recent days. Keratinous biological samples such as hair and nail have attracted the attention of clinical and forensic toxicologist when blood and urine sample especially were not taken in cases which were the decomposed and unfolded postmortem cases.
Drugs, medicines, drug of abuse and heavy metals may accumulate for a long time in hair and nail. The nail sample may be useful for toxicological analysis when the hair sample, which is a good marker for past use, is inadequate. Sample preparation and analytical methods to be used are important because of the complex structure of nail and low drug concentration detected in nail.
In this study, the basic structure of nail used as an alternative to toxicological analysis, the mechanism of drug or substance transfer into the nail, analytical methods, the advantages / disadvantages of nails and how to interpret the results will be examined.

Authors: Vitello Sylvia , Williamson Joanna
Published: November 2017

The distinction between external assessment and internal assessment underpins a major reform to vocational qualifications underway in England. To be approved by the Department for Education, vocational qualifications must now include a minimum proportion of external assessment, regardless
of subject. This paper discusses the nature and implications of this constraint on qualification design. First, it clarifies the meaning of external assessment and the key arguments underpinning the reform. Second, it evaluates the use and implementation of this blanket rule. The final section
discusses the nature of internal assessment in more detail, highlighting its heterogeneity and potential advantages over external assessment.
Comparing Tribal Research and Specimens Policies: Models, Practices, and Principles
Authors: Bardill Jessica
Published: November 2017

This article reviews a range of tribal policies regarding the proper solicitation, collection, disposition, and return or disposal of biological samples, or biospecimens, which include not only the sample itself but also data, such as genetic information, derived from the sample. These policies are not always found within tribal regulation, and many that exist emerge from a discrete set of models, such as from the American Indian Law Center (AILC), the Canadian Institutes of Health (CIHR), and the Indigenous Peoples Council on Biocolonialism (IPCB). Some policies merge language from these national models and conceptual papers with tribally specific foci, including incorporating tribal language for specific principles to guide research with that community and their biospecimens. The article concludes with recommendations for principles that emerge as paramount in the review for directing research involving biospecimens.

La composición del gasto gubernamental y el crecimiento económico en una economía dependiente
Authors: Casares Enrique R.
Published: November 2017

Estudiamos la relación entre el gasto gubernamental y el crecimiento económico en un modelo de crecimiento endógeno. Hay dos sectores productivos y dos bienes de consumo, los que participan y los que no participan en el comercio internacional. Hay dos exterioridades. Descubrimos que cuando el gobierno sólo gasta en bienes que participan (no participan) en el comercio internacional, la tasa de crecimiento de estado estacionario aumenta (disminuye). De igual modo, cuando el gobierno gasta en las dos clases de bienes, descubrimos una combinación de estos bienes en la que el gasto gubernamental no afecta la tasa de crecimiento de estado estacionario. Así pues, la distribución del gasto gubernamental entre las dos clases de bienes es un factor importante en la relación entre el gasto gubernamental y el crecimiento económico.
Desarrollo y desempleo. El modelo de Solow según una interpretación sinergética
Authors: London Silvia
Published: November 2017

La representación de fenómenos complejos propios de los sistemas económicos se encuentra en parte limitada en el análisis lineal. La formalización proveniente de los llamados “sistemas complejos” parece proporcionar un marco adecuado para la formalización de situaciones más cercanas a la realidad económica. Uno de los sistemas complejos más sencillos es la sinergética, o acción de conjunto, que considera fenómenos autoorganizados en los cuales las perturbaciones alrededor de un parámetro crítico se clasifican como estables o inestables. Según los valores relativos de los parámetros inestables el sistema se reorganiza hasta alcanzar una nueva solución, o vuelve al estado original.En este trabajo se reinterpreta el modelo básico de Solow según este tipo de modelización, con el propósito de incorporar la posibilidad de desempleo. La búsqueda se centra en encontrar cuándo un cambio en la tecnología causa desempleo temporal o estructural.
Bienestar social, óptimos de Pareto y equilibrios walrasianos
Authors: Accinelli Elvio , Brida Juan Gabriel , Plata Leobardo , Puchet Martín
Published: November 2017

En este trabajo analizamos la relación entre óptimos de Pareto y bienestar social. Cada distribución óptima de Pareto está asociada al conjunto de pesos sociales de una función de utilidad social. Toda ponderación posible de los agentes de la economía está asociada con un conjunto no vacío de asignaciones factibles óptimas de Pareto. Modificar el bienestar social asociado a los óptimos de Pareto alcanzables por una economía implica modificar la estructura de pesos sociales. No obstante, dada una distribución de dotaciones iniciales, no toda distribución de pesos sociales tiene asociada una asignación de recursos factible que sea, a su vez, un equilibrio walrasiano. Esta posibilidad depende de la distribución de las dotaciones iniciales. No cualquier distribución forzosamente da como resultado un equilibrio correspondiente al nivel más alto posible de bienestar agregado. ¿Es posible alcanzar este bienestar de manera descentralizada y sin participación de un planeador central’ La respuesta es que generalmente necesitaremos de una reasignación de las dotaciones sociales.
Redistribución de la riqueza usando derechos de consumo
Authors: Martínez C. Francisco , Rivera C. Jorge
Published: November 2017

La idea fundamental de este artículo es utilizar un mercado para producir una reasignación de la riqueza en una economía de intercambio. Este mercado es paralelo al mercado de bienes, y en él se comercian derechos de consumo que son inicialmente asignados por un planeador. Estas transacciones permiten generan una variedad de equilibrios de Walras, de manera equivalente a lo que se puede alcanzar mediante transferencias de dotaciones tipo suma alzada (lump-sum). En este trabajo se analiza el caso particular en que la dotación inicial de derechos de consumo es igualitaria para la población, con una regla simple de precios de derechos de consumo. La ventaja de este caso es que no se requiere información de las dotaciones iniciales de bienes de la población para lograr una reasignación de recursos que reduzca la brecha entre ricos y pobres.
Una solución dinámica para juegos con utilidades transferibles
Authors: Cesco Juan Carlos , Calí Ana Lucía
Published: November 2017

En este trabajo definimos un tipo de solución dinámica para juegos con utilidades transferibles. La solución dinámica fue introducida por Shenoy (1980) en el marco de juegos abstractos como un medio para describir algunos procesos de negociación. En el contexto de los juegos con utilidades transferibles estudiamos su comportamiento tanto en la clase de los juegos equilibrados (con Core no vacío) como en el de los juegos no equilibrados. En esta última subclase mostramos que la solución dinámica debe contener los elementos de ciertos ciclos de preimputaciones denominados ciclos maximales. Estos ciclos aparecen en relación con un esquema dinámico elaborado originalmente para aproximar puntos en el Core de un juego. En la subclase de los juegos equilibrados, la solución dinámica coincide con el Core, lo que establece un enfoque unificado de solución.El problema de existencia de ciclos maximales no está completamente resuelto, pero en algunas subclases de juegos podemos exhibir teoremas de existencia y una descripción completa de la solución dinámica.

Authors: Cuff Derek J. , Pupello Derek R. , Santoni Brandon G. , Clark Rachel E. , Frankle Mark A.
Published: November 2017

We previously evaluated 94 patients (96 shoulders) who underwent reverse shoulder arthroplasty using a central compressive screw with 5.0-mm peripheral locking screws for baseplate fixation and a center of rotation lateral to the glenoid as treatment for end-stage rotator cuff deficiency. The purpose of this study was to report updated results at a minimum follow-up of 10 years. Forty patients (42 shoulders) were available for clinical follow-up. In the patients available for study, implant survivorship, with the end point being revision for any reason, was 90.7%. Since our 5-year report, 2 patients underwent revision surgery; 1 patient sustained a periprosthetic fracture 7 years postoperatively and 1 patient had a dislocation because of chronic shoulder instability at 8 years postoperatively. At a minimum follow-up of 10 years, the patients continued to maintain their improved outcome scores and range of motion, which were comparable with earlier follow-up evaluations.

Reconsidering the Affordable Care Act’s Restrictions on Physician-Owned Hospitals
Authors: Courtney P. Maxwell , Darrith Brian , Bohl Daniel D. , Frisch Nicholas B. , Della Valle Craig J.
Published: November 2017

Background:

Concerns about financial incentives and increased costs prompted legislation limiting the expansion of physician-owned hospitals in 2010. Supporters of physician-owned hospitals argue that they improve the value of care by improving quality and reducing costs. The purpose of the present study was to determine whether physician-owned and non-physician-owned hospitals differ in terms of costs, outcomes, and patient satisfaction in the setting of total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods:

With use of the U.S. Centers for Medicare & Medicaid Services (CMS) Inpatient Charge Data, we identified 45 physician-owned and 2,657 non-physician-owned hospitals that performed ≥11 primary TKA and THA procedures in 2014. Cost data, patient-satisfaction scores, and risk-adjusted complication and 30-day readmission scores for knee and hip arthroplasty patients were obtained from the multiyear CMS Hospital Compare database.

Results:

Physician-owned hospitals received lower mean Medicare payments than did non-physician-owned hospitals for THA and TKA procedures ($11,106 compared with $12,699; p = 0.002). While the 30-day readmission score did not differ significantly between the 2 types of hospitals (4.48 compared with 4.62 for physician-owned and non-physician-owned, respectively; p = 0.104), physician-owned hospitals had a lower risk-adjusted complication score (2.83 compared with 3.04; p = 0.015). Physician-owned hospitals outperformed non-physician-owned hospitals in all patient-satisfaction categories, including mean linear scores for recommending the hospital (93.9 compared with 87.9; p < 0.001) and overall hospital rating (93.4 compared with 88.4; p < 0.001). When controlling for hospital demographic variables, status as a non-physician-owned hospital was an independent risk factor for being in the upper quartile of all inpatient payments for Medicare Severity-Diagnosis Related Group (MS-DRG) 470 (odds ratio, 3.317; 95% confidence interval, 1.174 to 9.371; p = 0.024), which may be because of a difference in CMS payment methodology.

Conclusions:

Our findings suggest that physician-owned hospitals are associated with lower mean Medicare costs, fewer complications, and higher patient satisfaction following THA and TKA than non-physician-owned hospitals. Policymakers should consider these data when debating the current moratorium on physician-owned hospital expansion.

This study was aimed to determine the impact of climate change on food crops performance in the Maluku province, based on the climatological data from 1995 to 2012, and to find out crop commodities that are adaptable to climate change. This study used four models of trend analysis: linear least square pattern, quadratic, exponential, and moving averages. The results of forecasting were used to estimate food crop production in the year of climate change to determine the impact of climate change on crop production. Results showed that soybean was the most sensitive crop to climate change, it had the biggest impact on production, yield declined on both El Nino (10.7%) and La Nina (11.4%). Paddy which is generally cultivated on the wetlands, El Nino had the smallest effect on a decrease of production of 2.9% and 2.4% increased on the La Nina. Corn production decreased 7.4% on the El Nino and 3.9% increased during the La Nina. Sweet potatoes was the most resistant crop to climate change, the impact was increased production by 2.5% during El Nino. To reduce the impacts of climate changes could be done through some efforts, namely: (1) to identify areas of potential drought, floods, pests and diseases endemic based on climate and soil conditions, (2) to develop prediction techniques, based on weather and climate forecasts to provide early warning to farmers, (3) to prepare and disseminate a package of technology which is able to withstand the adverse conditions of the El Nino and La Nina, including varieties, pest and disease prevention, and production inputs which are easily obtained by farmers, (4) to improve irrigation and drainage channels, mainly on the paddy fields to increase production capacity and to prevent crop failure during the dry season.

Research on hybrid rice in Indonesia was initiated in 1983, in collaboration with the International Rice Research Institute. Since 2000 private sector had indicated their interest in hybrid rice seed business. Planted area of hybrid rice in Indonesia was still relatively small of about 658 thousand hectares or about 5.0 percent of the total rice planted area of 13.2 million hectares in 2013. This study was aimed to analyze farmers’ responses and preferences to the development of hybrid rice in East Java, one of the rice production center in Indonesia. Contingent valuation method (CVM) to analyze farmers’ Willingness to Accept (WTA) and Willingness to Pay (WTP) with respect to various factors was then exercised to evaluate constraints and prospect of the future of hybrid rice development in Indonesia. The outputs of this study showed that farmers’ preferences to hybrid rice based on its taste was positive, especially to the newly introduced hybrid rice variety “Hipa Jatim”, when compared with the previous hybrid varieties, such as Maro and Rokan. WTA and WTP also showed significant farmers’ interests to the hybrid variety, due to higher yield and its better taste, similar to that of popular inbred rice. Farmers’ WTAs of hybrid rice was significantly influenced by the productivity, response to pests and deseases, and the total cost of production, while consummers’ WTPs of hybrid rice was significantly influened by the quality of milled rice.

Study on the intrinsic growth rate of natural increases of brown planthopper (BPH) was carried out in Sukamandi, Subang, West Java in 2012 at the screen house of Indonesian Center for Rice Research using host of two rice varieties, Pelita I/1 and Inpari 13. The study evaluated the effects of global climate changes on the development of brown planthopper after three decades since the first study in 1984. Results showed that the development of brown planthopper in Sukamandi, Subang field after a period of three decades was very different from the brown planthopper in 1984. The intrinsic rate of natural increase of BPH on Pelita I/1 was rm= 0.2285 wich was 2.22 fold in three decades and on Inpari 13 variety was rm = 0.2209 or 2.14 folds compared to that in 1984. Generation time of BPH on Pelita I/1 and on Inpari 13 was shorter by 0.81-0.83 times. The index of BPH survival on Pelita I/1 reached 5.2299 times and the index of the BPH survival on Inpari 13 reached 5.8881 times, compared to that of three decades ago. BPH development on Pelita I/1 showed that the ratio of females: males was 74%: 26%. In Inpari 13 variety showed the ratio females: males was 70.8%: 29.2%. Based on the description, the intrinsic growth rate of natural increases of brown planthopper had changed over three decades. The implications was that the population dynamics of brown planthopper had changed toward higher fitness as affected by global climate change.

Information on genetic diversity of QPM and Provit-A maize germplasm is important to support breeding program, in order to form a high yielding maize hybrid. Simple sequence repeats (SSR) have been extensively utilized as genetic markers to study the genetic diversity, cultivar identification, and gene mapping. The objectives of this research were to investigate the genetic diversity and to obtain information the genetic relationship among 20 maize accessions using 29 SSRs. The research was carried out at the Moleculer Biology Laboratory of Indonesian Cereals Research Institute (ICERI) in Maros, South Sulawesi. Twenty nine polymorphic primers that covered the 10 maize chromosomes were used to fingerprint the genotype of the lines, detecting 83 allels, with an average allel number of 3 allels per locus, ranging from 2 to 6 alleles per locus. The results indicated that polymorphism information content (PIC) ranged from 0.10 (nc133 and phi072) to 0.74 (phi064) with the average of 0.45. Genetic distance based on genetic similarity estimate ranged from 0.39 to 0.92. The high level of PIC values and wide genetic distances indicated the large variability among maize germplasm. Cluster analysis divided the 20 maize accessions into three groups. Coefficient cofenetic value (r) was 0.85 indicated a good fit based on the genetic similarity value. As many as 30 inbred heterotic recombinants were derived by incorporating 20 QPM and Provit-A with genetic distance of ≤0.65. The SSRs proved to be reliable and is practical technique for revealing the relationship among specialty maize genotypes.

Java is the most populated areas as well as the highest consumers of rice in Indonesia. Until now, rice which is widely consumed by the population of Java Island is still dominated by Ciherang, while planting the same varieties in long period time will cause ... This research aims to study the patterns of consumer preferences in Java on rice as one of the considerations for dissemination and assembly of new varieties. Evaluation is done by conducting sensory and physicochemical analysis on the five most widely purchased rice of each province on Java island. Hedonic and ranking test was assessed by 1000 panelists that were scattered in five provinces in Java. While the physicochemical analysis carried out in the Proximate Laboratory in Indonesian Center for Rice Research (ICRR), Sukamandi. In general, consumer preferences in each province in Java has a similar pattern except in DIY. Consumers in Java prefers rice with intermediate amylose content except those in DIY who like low amylose rice. Gelatinization temperature of rice is mostly high gelatinization temperature except those in DIY that dominated by low gelatinization temperature rice. Moreover, rice color influences consumer preferences in Java except on consumers in the West Java who chose the rice was not based on the level of rice white color.
