Authors: NURLIDIASARI MARLINA , BUDIMAN SYARIF
Published: January 2018

Coral reefs in Dcrawan Islands are astonishingly rich in the marine diversity. However, these reefs are threatened by humans. Destructive fishing methods, such as trawl, blasting and cyanide fishing practise, are found to be the main cause of this degradation. The coral reefs habitat reduction is also caused by tourism activities due to trampling over the reef and charging organic and anorganic wastes. The capabilities of satellite remote sensing techniques combined with field data collection have been assessed for the coral reef mapping and the change detection of Derawan Island. Multi-temporal Landsat TM and ETM images (1991 and 2002) have been used. Comparison of the classified images of 1991 and 2002 shows spatial changes of the habitat. The changes were in
accordance with the known changes in the reef conditions. The analysis shows the decrease of the coral reef and patchy seagrass percentage, while the increase of the algae composite and patchy reef percentage. Keywords : Coral Reef, Change Detection, Landsat-TM, Derawan

The preliminary study using Landsat ETM+ to estimate the rice production in Regency of Tabanan, Bali Province was conducted. The objectives of this study were to know spectral characteristic of rice plant in three importance growth periods of rice, and to develop a model to identify the distribution of rice. Landsat ETM+ in two acquisition dates (March 21st, 2003 and May 24*, 2003) were used in this study. Characteristics of rice were analyzed using radiance value of Landsat ETM+ obtained from converting digital number of Landsat data. Multi-variable linear regression analysis was developed to classify the rice in its growth period. The result showed that the rice plant has different reflectance in seedling-development period, ear differentiation period and maturation period. It is
expressed by the radiance value of Landsat ETM+. However, spectral characteristic of rice in each band of Landsat ETM+ is similar to the green vegetations in general, except in blue
band (Bl). Based on statistical analysis, the classification of rice in each its growth period can be classified. Key words: Rice field, Landsat ETM+, Spectral Characteristic, Multi-temporal.

Published: January 2018

Princeton Ocean Model (POM) was used to calculate the tidal current and M2-residual current in Benoa Bay using barotropic model (mode 2). The model was forced by tidal elevation, which was given along the open boundary condition using tide data prediction from Hydro-Oceanography Division-Indonesian Navy (DISHIDROS TNI-AL). The computed tidal current and residual current have been compared with both data in Benoa Bay, that are data of the open boundary of Benoa Bay and condition of Benoa Bay after developed a port and reclamation of Serangan Island. The maximum velocity of tidal current for open boundary conditions at flood tide is 0.71 m/sec, whereas at ebb tide is 0.65 m/sec and the maximum velocity after developed a port and reclamation of Serangan Island, at flood tide, is 0.69 m/sec. The simulation of residual current with particular emphasis on predominant constituent of M2 after developed a port and reclamation of Serangan Island shows a strong flow at the western part of Tanjung Benoa and Benoa Harbor and also at bay mouth between Serangan Island and Tanjung Benoa. Maximum velocity of M2-residual current is 0.0585 m/sec by the simulation and showed that the
current which was produced forming two eddies in the bay of which one eddy is in the mouth of bay in southern part. The residual current for open boundary condition of bay shows four eddies circulation, one big eddies and the others small. The anticlockwise circulation occurs in the inner part of the bay.

The water masses in both routes of Indonesia Throughflow (ITF) from historical hydrographic data are examined by means of the Principal Component Analysis (PCA), a multivariate statistical technique, during the southeast monsoon and northwest monsoon, and compared with the TS diagrams. The temperature and dissolves oxygen always play in the same PC, which describeds a variability contribution of the water mass characters, while salinity in a different PC. The relationship of the water masses parameters may indicate the character of dissolved oxygen as a non-conservation tracer. The Principle Component Analysis may also be used to follow the trendds of core layer attenuation as verified by the salinity corresponds at the PC. It will be higher with S-max and S-min and more closely resemble the sources. This condition is shown in the waters close to the main sources in the Pacific, like Sulawesi, Malkuku and Halmahera Sea, where both the salinity extrema can still be observed. Conversely, in the Banda and Timor Sea, where S-max and S-min are greatly attenuated even completely remove, the correspondence of salinity in the water mass character variability becomes smaller. As seen on TS and TO diagrams, PCA graphics are also showed the dominant of the north Pacific water in the western route seas, the Sulawesi, Makasar Strait and the Florest Sea, but relatively salty water of South Pacific origin is observed in the Halmahera Sea, particularly in the northwest monsoon. The strong seasonal variablity of surface water in the Indonesian can also be observed in the PCA graphics. Keywords: Water Mass, Indonesian Throughflow, PCA.

Sea-sand mining has both advantages particularly in its destructive capabilities. The damages caused by sea-sand mining are mostly due to the unorganized mining zones. In order to minimize the negative effects of mining activities, the well-organized mining zones that have evaluated all related aspects are required. There are several aspects which are closely related to the sea-sand mining zones , one of those is hydro-oceanography aspects in its relation with the sea environments. A comprehensive analysis can be made by integrating hydrooceanography and GIS as a system of both data-organizer and software. This method is supported by using the remote sensing technology as a verification data comparison to the results of hydrooceanography analyses. The application of image analysis as a verification tool is a good method to proof the results given by the numerical simulation model. In this study, we use the Landsat images as the data analysis have indicated that the mining can be continously conducted in several locations without imposing any hazardous impacts to the adjacent environment. By considering the results above, in integrated system between the numerical model and the GIS in highly effective as a foundation to determine the mining zone where the negative effects of the oceanographic-dynamical-changes on the environment due to the mining activities can be easily recognized and predicted.

Application of data from field to satellite observation and simulation has been made as present understanding of Aceh tsunami. Tsunami has attracted attention after struck Aceh in December 26th 2004, generated by a strong eartquake with magnitude Mw=9.0. The eatrhquake triggered giant tsunami waves that propagated throughout the Indian Ocean, causing extreme inundation and destruction along the northern and western coast of Sumatra. Within hours, the tsunami devastated the distant shores of Thailand to east as well as Sri Lanka, India and Maldives to the west. The tsunami also caused deaths, and destruction in Somalia and other nations of East Africa. The tsunami was recorded on tidal stations throughout the Indian Oceans in worldwide. Unlike the Pacific, the Indian Ocean does not yet have a network of deep-ocean pressure sensors, and so coastal tide gauges provide the only direct measurement of Indian Ocean stunami amplitudes. We had many lessons and basic knowledge which had already been learned from this tragic event in the Indian Ocean. Many more lessons should be learned in the near future as this tragedy unfolds and reverals many failures to value and protect human life in this neglected region of the world.

It started as natural gas exploration project and punctured a geological structure at a depth of 2,8 km, releasing unprecedented volume of hot mud volcano (5x104 mcubix per day). By November 2006, it was estimated that hot mud had spread over (2,89 plus minus 0,10) x 106 m, swamping several villages with more than 10.000 people evacuated. In this research, by employing the advantage of spatial perspective of remote sensing imagery, the extent of hot mud spreading area and temperature distributions are derived from satellite images of the advanced Spaceborn Thermal Emission and Reflection Radiometer (ASTER) sensor onboard the Terra satellite. The mud spreading are was calculated using three visible or near infrared channels having a resolution of 15 m. Temperature distributions were calculated using the temperature or emissivity separation (TES) method on five thermal infraredchannels with a resolution of 90 m. The standard and water vapor scaling (WVS) methods were applied in the atmospheric correction process prior to the TES process. The result showed that the mud continued spreading during five months after the eruption. After 3-5 months from the eruption, the estimated temperature was about 30-69 degree of celcius in the mud spreading area. Also, estimations of the volume and weight of the hot mud were made on the basis of the visible of level 3 A product of ASTER and ground survey data.

Published: January 2018

Abstract. ALOS satellite is one of the natural resources satellites that can be used for 3D

model applications. The problems of 3D model generation based on satellite imagery are

the model always in Digital Surface Model (DSM), not in Digital Elevation Model (DEM).

The reference system of 3D model that are produced by ALOS satellite image is still as

surface for z axis, whereas x axis and y axis has been closed to 2D reference system in

some certain datum and system of map projection. Therefore, it needs a research to observe

the accuracy and the precision of ALOS satellite data using a least square adjustment in

parameter methods. The results of this research will be used as a reference for next research

to find a way for changing DSM from ALOS satellite image to be DEM automatically.

Abstract. Digital Elevation Model (DEM) was generated from Advanced LandObservation Satellite - The Panchromatic Remote-Sensing Instrument for Stereo Mapping(ALOS PRISM) stereo data using image matching and collinear correlation based on LeicaPhotogrametry Suite (LPS) software. The process needs three dimension of Ground ControlPoint (GCP) or Control Point (CP) XYZ as input data for collinear correlation to determineexterior orientation coefficient. The main problem of the DEM generation is the difficultyto obtain the accurate field measurement GCP in many areas. Therefore, another alternativeCP sources are needed. The aim of this research was to study the possibility of (IKONOS)image and Shuttle Radar Topography Mission (SRTM) X-C band to be used as CPreference for ALOS PRISM DEM generation. The study area was Sragen and Bandungregion. The DEM of each study area was generated using 2 methods: generated using fieldmeasurement GCPs taken by differential GPS and generated using CPs from IKONOSimage (XY coordinat) and SRTM for (Z elevation). The generated DEMs were compared.The accuracy of both DEMs were evaluated using another field measurement GCPs. Theresult showed that the generated DEM using CPs from IKONOS and SRTM X-C hadrelatively same height pattern and height distribution along transect line with the DEMusing GCPs. The absolute accuracy of the DEM using CPs was about 60% - 80% lessaccuracy comparing to the DEM using GCPs. This research showed that IKONOS imageand SRTM X-C band can be considered as good alternative CP source to generate highaccuracy DEM from ALOS PRISM stereo data.

Published: January 2018

A long-term climate variations in the western Indonesian region (e.g. Sumatera) were evaluated using precipitation data as a proxy. The result showed that there was a long-term climate variation over Sumatera region indicated by a decreasing trend in precipitation (drying trend). Moreover, the long-term precipitation trend has a strong seasonality. Remarkable decreasing trend at a rate of 3.9 cm/year (the largest trend) was observed during the northwest monsoon (DJF) season, while the smallest decreasing trend of 1.5 cm/year occurred during the southeast monsoon (JJA) season. This result suggested that the Sumatera Island experienced a drying trend during the northwest monsoon season, and a dryer condition will be more frequently observed during the southeast monsoon season. The long-term precipitation over the Sumatera Island was linked to coupled air-sea interactions in the Indian and Pacific oceans. The connection between the seasonal climate trends and sea surface temperature (SST) in the Indian and Pacific oceans was demonstrated by the simultaneous correlations between the climate indices (e.g. Dipole Mode Index (DMI) and the Niño3.4 index) and the precipitation over the Sumatera Island. The results suggested that both the Indian Ocean Dipole (IOD) and the El Niño-Southern Oscillation Index (ENSO) have significant correlation with precipitation. However, remarkable correlations were observed during the fall transition of the IOD event.

Tidal flood or ‘rob’ is a serious problem in many coastal areas in Indonesia, including Pekalongan in the northern coast of Java island. This study aimed to simulate the flood inundation area for different scenarios of sea level rise, also to investigate the possibility of land subsidence that may further aggravate the problem of flooding in Pekalongan. In this study, the MIKE-21 model was used to simulate and predict the flood inundation area. Tidal data were generated from the Tide Model Drive (TMD). The tidal flood simulations were carried out for three different scenarios of sea level rise: 1) current situation, 2) next 50 years, assuming no sea level rise, and 3) next 50 years, assuming 50 cm of sea level rise. Based on the results, the ranges of water level rise in Pekalongan for each scenario were 0.23-1.27 m, 0.36-1.38 m, and 0.65-1.53 m, respectively. Meanwhile, ground displacement maps were derived from the ALOS/PALSAR data using Differential Interferometric Synthetic Aperture Radar (D-InSAR) technique. Twelve level 1.0 images of ALOS/PALSAR data acquired in ascending mode during 2008 to 2009 were collected and processed in time-series analyses. In total, 11 pairs of interferogram were produced by taking the first image in 2008 as the master image. The results showed that the average of land subsidence rate in Pekalongan city was 3 cm/year, and the subsidence mainly occurred in the western part of the city.

Authors: Siwi Sukentyas Estuti
Published: January 2018

Image fusion, commonly known as pan-sharpening, is a method that combines two data: a panchromatic image that has geometric detail information with the highest spatial resolution and multi-spectral image that has the highest color information but with the lowest resolution. Pan-sharpeningis very important for various remote sensing applications, such as to improve the image classification, to change the detection using temporal data, to increase the geometric, image segmentation, and to improve the visibility of certain object that does not appear on certain data. This study aims to compare the existing pan-sharpening methods such as Brovey, Brovey modification using green and red band, Gram-Schmidt, HPF, Multiplicative, and SFIM.The quality of the pan-sharpening result should be evaluated, this study used Universal Image Quality Index (UIQI/Q index); this evaluation methodgives the opportunity to choose which method is best to provide the most similar spectral information with the original multispectral image. A pan-sharpening qualitative analysis shows that there has been a sharpening process on all pan-sharpening images. Based on spectral visualization (color display), several pan-sharpening methods such as HPF multiplicative method provides brighter colorsand Brovey transformation method displays dark colors. Gram-Schmidt method also provides a different color from the original multispectral image. A pan-sharpening quantitative analysis shows that the best pan-sharpening method with UIQI value> 0.9 is Brovey modification using green and red band. This is due to the green band (500-590 nm) and the red band(610-680 nm) wavelength are in the panchromatic band (480-710 nm) of the SPOT-5 Data.

Published: January 2018

Land conversion occurred in the lake catchment area caused the decreasing of water quality in many lakes of Indonesia. According to Lake Ecosystem Management Guidelines from Ministry of Environment, tropic state of lake water is one of parameters for assessing the lake ecosystem status. Tropic state can be indicated by the quantity of nitrogen, phosphorus, chlorophyll, and water clarity. The objective of this research is to develop the water quality algorithm and map the water clarity of lake water using Landsat 8 data. The data were standardized for sun geometry correction and atmospheric correction using Dark Object Subtraction method. In the first step, Total Suspended Solid (TSS) distributions in the lake were calculated using a semi empirical algorithm (Doxaran et al., 2002), which can be applied to a wide range of TSS values. Secchi Disk Transparency (SDT) distributions were calculated using our water clarity algorithm that was obtained from the relationship between TSS and SDT measured directly in the lake waters. The result shows that the water clarity algorithm developed in this research has the determination coefficient that reaches to 0,834. Implementation of the algorithm for Landsat 8 data in 2013 and 2014 showed that the water clarity in Kerinci Lake waters was around 2 m or less, but the water clarity in Tondano Lake waters was around 2 – 3 m. It means that Kerinci Lake waters had lower water clarity than Tondano Lake waters which is consistent with the field measurement results.

Authors: Indradjad Andy , Salyasari Noriandini Dewi , Arief Rahmat
Published: January 2018

Remote sensing data could experience damage due to sensor failure or atmospheric condition. Reconstruction technique to retrieve the missing information had been widely developed in the past few years. This writing aimed to provide a technique to recover reflectance information of Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Band 6. Since Band 6 Aqua MODIS experienced sensor failure, lots of information would be missing. There were three kinds of methods used in repairing such damage. Two of which were categorized as spatial-based methods, i.e. NaN interpolation method and tensor completion method. Whereas, another method was a spectral-based one. NaN was an interpolation method to reconstruct missing value; while tensor completion method utilized low rank approximation, and spectral method used correlation between Band 6 and Band 7 which had near wavelength. Implementation of these methods was resulted in reconstruction of Aqua Modis Band 6 data which was damaged due to detector disfunction on Aqua Satellite. Peak Signal to Noise Ratio (PSNR) value of this method was 41 dB, meaning that reconstruction technique provided positive impacts for data improvement.

Published: January 2018

Drought is becoming one of the most important issues for government and policy makers. National food security highly concerned, especially when drought occurred in food production center areas. Climate variability, especially in South Sulawesi as one of the primary national rice production centers is influenced by global climate phenomena such as El Niño Southern Oscillation or ENSO. This phenomenon can lead to drought occurrences. Monitoring of drought potential occurrences in near real-time manner becomes a primary key element to anticipate the drought impact. This study was conducted to determine potential occurrences and the evolution of drought that occurred as a result of the 2015 El Niño event using the Vegetation Health Index (VHI) from the National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) satellite products. Composites analysis was performed using weekly Smoothed and Normalized Difference Vegetation Index (or smoothed NDVI) (SMN), Smoothed Brightness Temperature Index (SMT), Vegetation Condition Index (VCI), Temperature Condition Index (TCI), and  Vegetation Health Index (VHI).  This data were obtained from The Center for Satellite Applications and Research (STAR) - Global Vegetation Health Products (NOAA) website during 35-year period (1981-2015). Lowest potential drought occurrences (highest VHI and VCI value) caused by 2015 El Niño is showed by composite analysis result. Strong El Niño induced drought over the study area indicated by decreasing VHI value started at week 21st. Spatial characteristic differences in drought occurrences observed, especially on the west coast and east coast of South Sulawesi during strong El Niño. Weekly evolution of potential drought due to the El Niño impact in 2015 indicated by lower VHI values (VHI < 40) concentrated on the east coast of South Sulawesi, and then spread to another region along with the El Nino stage.

Published: January 2018

Indonesian society needs information on potential hydrometeorological disasters, therefore the development of rainfall estimation methods becomes an important research activities to support disaster risk reduction. Central Kalimantan were selected as research location for comparative test of rainfall estimation methods based on Himawari-8 IR1 (11μm) data, because it has area with cloud cover fairly intensive throughout the year. Some rainfall estimation methods tested in this research are AE, CST, CSTM, IMSRA. Non Linear Relation, and Non Linear Inversion. Each of these methods tends to have a weakness in the value of accuracy, so this research aims to determine the most accurate method to be applied in Palangkaraya (27 meters above sea level) city and Muratewe (60 meters above sea level) district in Central Kalimantan. The experiment was conducted during the period of highest rainfall in January and February 2016 by converting the temperature data cloud tops (IR1) into a precipitation with AE, CST, CSTM, IMSRA, Non Linear Relation and Non Linear Inversion method. Based on the results of quantitative analysis, it was known that IMSRA was the best method which can be applied in rainfall estimation in Muarateweh’s and Palangka Raya’s winter period. The Accuracy of all estimation methods decreased when it was applied in Palangka Raya at afternoon and in Muarateweh at night until early morning. The estimation method with the lowest score was the AE with an average MSE value > 90 and the best estimation method was IMSRA with MSE value <12.
A PARTIAL ACQUISITION TECHNIQUE OF SAR SYSTEM USING COMPRESSIVE SAMPLING METHOD
Authors: Arief Rahmat
Published: January 2018

In line with the development of Synthetic Aperture Radar (SAR) technology, there is a serious problem when the SAR signal is acquired using high rate analog digital converter (ADC), that require large volumes data storage. The other problem on compressive sensing method,which frequently occurs, is a large measurement matrix that may cause intensive calculation. In this paper, a new approach was proposed, particularly on the partial acquisition technique of SAR system using compressive sampling method in both the azimuth and range direction. The main objectives of the study are to reduce the radar raw data by decreasing the sampling rate of ADC and to reduce the computational load by decreasing the dimension of the measurement matrix. The simulation results found that the reconstruction of SAR image using partial acquisition model has better resolution compared to the conventional method (Range Doppler Algorithm/RDA). On a target of a ship, that represents a low-level sparsity, a good reconstruction image could be achieved from a fewer number measurement. The study concludes that the method may speed up the computation time by a factor 4.49 times faster than with a full acquisition matrix.

Published: January 2018

LAPAN has developed remote sensing data collection by using a pushbroom linescan imager camera sensor mounted on LSA (Lapan Surveillance Aircraft). The position accuracy and orientation system for LSA applications are required for Direct Georeferencing and depend on the accuracy of off-the-shelf integrated GPS/inertial system, which used on the camera sensor. This research aims to give the accuracy requirement of Inertial Measurement Unit (IMU) sensor and GPS to improve the accuracy of the measurement results using direct georeferencing technique. Simulations were performed to produce geodetic coordinates of longitude, latitude and altitude for each image pixel in the imager pushbroom one array detector, which has been geometrically corrected. The simulation results achieved measurement accuracies for mapping applications with Ground Sample Distance (GSD) or spatial resolution of 0,6 m of the IMU parameter (pitch, roll and yaw) errors about 0.1; 0.1; and 0.1 degree respectively, and the error of GPS parameters (longitude and latitude) about 0.00002 and 0.2 degree. The results are expected to be a reference for a systematic geometric correction to image data pushbroom linescan imager that would be obtained by using LSA spacecraft.

Published: January 2018

La prevalencia de sobrepeso y obesidad se ha incrementado de una forma muy notable en las últimas décadas y constituye un gran problema de salud pública tanto en España como en la mayoría de los países desarrollados. El sobrepeso y la obesidad incrementan el riesgo de padecer muchas otras patologías como enfermedades cardiovasculares, insulín-resistencia, diabetes tipo 2, hipertensión, dislipemia y ciertos tipos de cánceres. En este contexto, el aumento de la esperanza de vida en nuestro medio, determina que en residencias de ancianos la prevalencia de diabetes haya aumentado del 16 al 23 por ciento en el periodo de 1996-2004. Además hay que tener en cuenta que los adultos mayores con diabetes sufren un exceso de morbilidad y mortalidad en comparación con aquellos sin diabetes, lo que unido a sus características de base, complica su manejo. Es frecuente encontrar en estos pacientes polifarmacia, discapacidades funcionales, así como síndromes geriátricos comunes como deterioro cognitivo y riesgo de caídas. Recientemente se ha comercializado lixisenatide (LIX). Se trata de un análogo de GLP-1 de acción corta. Hemos realizado un estudio en el que nuestro objetivo es evaluar el efecto sobre el control glucémico y otras variables metabólicas mediante la adición de lixisenatide (LIX) a una cohorte de pacientes mayores de 65 años tratados con la terapia de combinación de agentes orales e insulina basal (BOT).

Authors: Del Águila Jesús
Published: January 2018

El presente estudio versa sobre la repercusión de la discapacidad en el Impuesto sobre la Renta de las Personas Físicas. En primer lugar, se establece el deber general de los poderes públicos de realizar una política orientada a la protección del colectivo discapacitado, los derechos de los discapacitados y el reparto de competencias existente en materia de IRPF entre el Estado y las Comunidades Autónomas. Se partirá de un estudio sobre el concepto de discapacidad que establece la Ley 26/2014, de 27 de noviembre, que modifica a la Ley 35/2006, de 28 de noviembre. Así mismo, se explicará cómo influye la discapacidad en la capacidad económica del contribuyente. Por último, se hará alusión a los requisitos necesarios para la obtención del certificado que acredita la discapacidad. Por otro lado, se realizará un análisis de las distintas medidas adoptadas en la Ley del IRPF haciendo hincapié en las exenciones que establece la Ley 26/2014 del IPRF. Se estudiará, la influencia de la discapacidad en los rendimientos del trabajo, en los rendimientos de las actividades económicas y en las ganancias y pérdidas patrimoniales. En este parte se tratarán también los cambios que ha introducido la entrada en vigor de la Ley 26/2014 y su incidencia en la mejora de las cuantías a deducir por conceptos de “contribuyente discapacitado”.

Published: January 2018

En la etapa de la vejez es importante el estudio de las emociones y de cómo éstas afectan en la adaptación y calidad de vida de las personas mayores. Algunos autores ponen de manifiesto la importancia de la inteligencia emocional y la calidad de vida. La alexitimia supone una dificultad en la identificación y descripción de las emociones y un estilo cognitivo orientado hacia lo externo. El objetivo es estudiar la relación entre inteligencia emocional, calidad de vida y alexitimia en un grupo de ancianos. Los participantes fueron 25 ancianos de un centro institucionalizado de la Región de Murcia, siendo 12 hombres. Se emplearon los siguientes cuestionarios: Inventario Breve de Inteligencia Emocional para Mayores (EQ-I-M20), Cuestionario de Evaluación de Calidad de Vida en contexto Residencial (CECAVIR) y la Escala abreviada de Alexitimia de Toronto (TAS-20). Se encontraron correlaciones significativas positivas entre: la dificultad para identificar sentimientos y las relaciones sociales y familiares; la dificultad para identificar sentimientos y satisfacción con la vida; la dificultad para describir sentimientos y las relaciones sociales y familiares, así como una correlación significativa negativa entre dificultad para describir sentimientos y adaptabilidad. Los resultados permitirán avanzar en la implantación de actividades que promuevan el desarrollo emocional de las personas mayores institucionalizadas en pro de su calidad de vida.
Sobrecarga y salud percibida en cuidadores informales de pacientes con enfermedad mental

Published: January 2018

La enfermedad mental puede provocar a la persona que la padece una gran dependencia, impidiéndole continuar de forma autónoma con su vida y provocándole la necesidad de ayuda y cuidados por parte de otras personas. Este cuidado es asumido de forma principal por un familiar próximo que generalmente es mujer y madre del afectado/a. Esta situación provoca en la cuidadora una sobrecarga. El objetivo del estudio es conocer el nivel de sobrecarga y de salud percibida de una muestra de 30 cuidadores de personas con deterioro mental grave y comprobar si existen diferencias, con respecto a una serie de variables como el apoyo externo recibido, los servicios de ayuda utilizados, el tiempo y grado de dependencia de la persona cuidada, entre otras. Para evaluar la salud percibida se ha utilizado el Cuestionario de Salud General de Goldberg; se emplea la Escala de Sobrecarga del cuidador de Zarit; y la Escala de Lawton y Brody para las actividades instrumentales de la vida diaria. Los resultados evidencian que más de la mitad de los cuidadores de la muestra no manifestaron percepción de sobrecarga; sin embargo, la mayoría sí afirmaron tener una mala salud general percibida. Los niveles más altos de sobrecarga se corresponden con las peores percepciones de salud.
Una perspectiva sociocultural acerca la paternidad: el caso de la paternidad adoptiva
Authors: Salvatore Sergio , Gennaro Alessandro , Dell’Anna Antonio
Published: January 2018

El documento analiza la paternidad desde el punto de vista socio-cultural. La psicología contemporánea, más allá de las diferentes perspectivas teóricas, reconoce a la crianza de los hijos una función autónoma y procesal, en gran medida dependiente de dinámicas intra-psíquicas o de dimensiones intersubjetivas y microsociales que, sin embargo, pueden ser capaces de tener un impacto en los aspectos subjetivos internos. Este trabajo propone la recuperación de una perspectiva culturalista de la crianza, con el objetivo de analizar esta característica humana superior, como el resultado de las dinámicas culturales. Esta perspectiva sugiere que el ejercicio de la función de los padres es contextual y culturalespecífica; es decir, que la forma en que se lleva a cabo depende de, y está constituida por los significados culturales que median su acción. Para el desarrollo de esta perspectiva, el presente trabajo se centra en una condición "límite", la adopción, centrándose en la dinámica subyacente a la competencia parental. En la segunda parte se definen algunas implicaciones pragmáticas sobre el papel y el propósito de la evaluación psicológica con los padres su interés en la adopción.
Las relaciones románticas en adolescentes con problemas interiorizados y exteriorizados.
Authors: Tani Franca , Smorti Martina
Published: January 2018

El objetivo principal de este estudio fue examinar la influencia que cada problema psicológico tiene en la participación y la calidad las relaciones amorosas de los adolescentes. Para este estudio fue reclutada una muestra de 621 adolescentes (308 varones y 313 mujeres) con edades comprendidas entre 14 y 17 años. Los problemas psicológicos fueron evaluados mediante Youth Self-Report que evalúa los problemas de externalización (conductas agresivas, disruptivas, hiperactivas, antisociales y delictivas) y de internalización (depresión, ansiedad y aislamiento social). En contraste con los estudios anteriores, se han diferenciado los problemas de externalización e internalización "puros" de las formas de comorbilidad de trastornos psicológicos. Para explorar los aspectos cuantitativos de las relaciones amorosas se ha utilizado el número total de parejas y la media de la duración de las relaciones. Fueron empleados un inventario de relación y un inventario de satisfacción en la relación para medir el positivo (el compañerismo, la intimidad, la alianza y el apoyo fiable) y negativo (conflicto, antagonismo e influencia). Los resultados mostraron que los adolescentes con externalización pura o con problemas de comorbilidad, reportaron un mayor número total de parejas con respecto a los adolescentes con problemas de internalización pura. Además, tenían relaciones amorosas caracterizadas por rasgos cualitativos más negativos.
Comunicación emocional: rastrear aspectos de la libre expresión en las pinturas de los niños de educación preescolar
Authors: Stamatis Panagiotis J.
Published: January 2018

Esta investigación se centra en la capacidad de los niños griegos de educación preescolar, a auto-expresarse a través de la pintura espontánea en un tema de su elección, sin revelar sus emociones. El método de esta investigación está basado en los análisis que se centran en el contenido, el tamaño, el uso de papel y el color que fue elegido por los niños. Por otra parte, factores como el género y la situación socio-económica de los niños correlacionaron con su capacidad de expresarse. La observación y el análisis de datos de los colores que los niños han seleccionado, las formas que pintaron y las dimensiones de sus pinturas, facilitaron información importante por su capacidad de expresar sus emociones. La mayoría de los niños en edad preescolar expresó sus pensamientos y sentimientos haciendo imágenes coloridas, en un esfuerzo para representar a sus familiares con las imágenes que revelan sus relaciones con sus padres o hermanos. La capacidad de los niños de auto-expresión es una parte de su creatividad, la comunicación mental y emocional con que ellos construyen interactivamente sus relaciones sociales con otros niños y sus maestros y padres, en un nivel de iniciativa. Como la investigación reveló, la pintura ayuda a los niños a expresar espontáneamente sus pensamientos y sentimientos reales, positivos y negativos.

El principal objetivo de este estudio era investigar los efectos de la capacidad de memoria en el Trabajo (CMT) en los estudiantes, y la forma de resolver los ejercicios matemáticos planteados, mientras se consideraban diferentes factores psicológicos. En una muestra de 256 estudiantes mujeres entre los desde Teherán 17 y 18 años fueron evaluadas en a) Inventario conciencia meta cognitiva (ICM), (b) Prueba de atención Matemáticas (PAM), (c) Escala de ansiedad ante mas matemáticas (EAAM), (d) Prueba “Digit Span Backward”, y (e) un examen de Matemáticas. Los datos del presente estudio se analizaron mediante estadística descriptiva e inferencial de T-test y correlación de Spearman con el Paquete Estadístico para las Ciencias Sociales (SPSS). Los resultados indicaron que la meta cognición tiene distintivos y distintas variables desafiantes que otros factores usados en el WMC en la resolución de problemas matemáticos. En otras palabras, la superioridad correlación entre WMC y el rendimiento matemático se encontró en el grupo de alta metacognición. Además, en cada grupo de baja/ alta metacognición, atención alta/ baja de matemáticas, y bajo altos niveles de ansiedad/ matemáticas, los estudiantes con alta WMC mostraron mejor rendimiento matemático de los bajos de WMC. Los resultados del estudio son adecuados para los investigadores que estén interesados en los diferentes factores que influyen en los problemas matemáticos que los estudiantes resuelven.
