Published: January 2017

Un tema emergente en el ámbito de la educación superior en México es el estudio de las conductas éticas y no éticas de los miembros de la comunidad académica. En los últimos años estas últimas se han incrementado al grado de preocupar a las instituciones educativas, las cuales buscan definir cuáles son dichas prácticas no éticas y en qué condiciones se presentan, por ejemplo, debido a la fuerte presión a la que están sometidos los académicos, por las múltiples evaluaciones de su productividad y la calidad de su producción científica. El objetivo de este artículo es identificar la relación entre las conductas éticas y no éticas en la producción científica y las demandas de calidad-productividad; inferir los efectos de dicha presión en la salud de los académicos y mostrar si dichas conductas se presentan entre la comunidad académica de dos programas educativos adscritos al Programa Nacional de Posgrados de Calidad, del Consejo Nacional de Ciencia y Tecnología de México. El presente estudio recupera una investigación realizada con académicos, utilizando una metodología de corte cualitativo y como instrumento de indagación la entrevista en profundidad. El artículo inicia exponiendo lo que expresa la literatura sobre los requerimientos de calidad en las instituciones de educación superior, las conductas éticas y las conductas cuestionables. Por último, se discuten algunos resultados de la investigación y se llega a conclusiones.

Authors: Sari Nurwita Mustika , Kushardono Dony 
Published: January 2017

The use of Unmanned Aerial Vehicle (UAV) to take aerial photographs is increasing in recent years. Photo data taken by UAV become one of reliable detailed-scale remote sensing data sources. The capability to obtain cloud-free images and the flexibility of time are some of the advantages of UAV photo data compared to satellite images with optical sensor. Displayed area at the data shows the objects clearly. Rural area has certain characteristics in its land cover namely ricefield. To delineate the area correctly there is an object-based image analysis methods (OBIA) that could be applied. In this study, proposed a novel method to execute the separation of objects that exist in the data with segmentation method. The result shows an effective segmentation method to separate different objects in rural areas recorded on UAV image data. The accuracy obtained is 90.47% after optimization process. This segmentation can be a valid basis to support the provision of spatial information in rural area.

Authors: Miardini Arina , Susanti Pranatasari Dyah 
Published: January 2017

Watershed conditions in Indonesia have been degraded over time, which is marked by increasing area of critical land. The vast area of critical land was evidenced to be a serious threat for watershed carrying capacity which eventually affected the hydrology imbalance in the watershed area. One among watershed with degraded lands which seriously requires priority handling is Comal watershed. The purpose of this study is to identify the physical characteristics of Comal watershed which have significant influence in determining the runoff and calculating the runoff coefficient by taking into account the parameters of watershed’s physical characteristics. The method used in this analysis is Cook method, which is done through the estimation of runoff coefficient by evaluating the parameters of slope, infiltration, vegetation cover, and drainage density. The unit of analysis in this study is land mapping unit. Results of the four parameters are classified and the classification is done so that the scores of the runoff coefficient are figured out, while the peak discharge determination is performed by using the Rational method. The analysis showed that runoff coefficient of Comal watershed is 61.63%, which can be categorized as high. The runoff coefficients and peak discharge calculations of each sub watershed, respectively, Comal Hilir of 52.65% with peak discharge 505.68 m3/sec, Genteng of 65.04% with peak discharge 542.44 m3/sec, Lomeneng of 64.00% with peak discharge 194.23 m3/sec, Srengseng of 64.10% with peak discharge 270.46 m3/sec, and Wakung Hulu of 62.34% with peak discharge 686.64 m3/ sec. The most influential runoff coefficient factors are, respectively, infiltration rate, slope, vegetation cover, and drainage density. Flood control priority in Comal watershed should be preoccupied to increase the infiltration rate through a combination of three conservation techniques of mechanical, vegetative, and biology.
Evaluation of Satellite Image Correction Methods Caused by Differential Terrain Illumination
Authors: Santosa Purnama Budi 
Published: January 2017

The problem due to differential terrain illumination on satellite imagery is experienced by most of areas which are on mountainous terrain. This may cause variations in reflectance of similar ground features which lead to a misclassification of land cover classes due to different topographic positions. This phenomenon most commonly occurred in the areas which are located on southern and northern hemisphere because of the low sun inclination. This problem has been a major interest for researchers to be solved prior to the land cover classification process. For satellite images which experience this kind of problem, topographic correction need to be applied in order to reduce the illumination effects prior to land cover classification process. This research is aimed at conducting topographic correction of multi spectral SPOT satellite data as well as evaluating the three topographic correction methods. They are Cosine which is based on Lambertian reflectance assumption, as well as Minnaert correction and C correction methods which are based on non-Lambertian reflectance assumption. The data used in this study are two scenes of SPOT images of forested mountainous area of Miyazaki Prefecture, Kyushu, Japan. Research steps had been conducted in this study including geometric correction, sample data collection for calculating Minnaert constants and C constants at location which represents the whole study area, topographic correction for two scenes SPOT images, and results analysis. The results show that Cosine method did not show good performance for the study area which is topographically dominated by rugged terrain. Whereas Minnaert method and C method gave satisfactory results as is indicated by the statistical data as well as visual interpretation. However the Minnaert correction method showed slightly better performance than the C correction method.

Published: January 2017

Makassar is one of Indonesian big cities with rapid growth rate, but not totally safe from earthquake hazard. This condition led study on affected population by earthquakes in this city are important to do. This paper estimated the population of Makassar City threatened by the probabilistic earthquake hazard. In this current study, earthquake hazard in the forms of peak ground acceleration (PGA) and spectral acceleration, estimated by using Probabilistic Seismic Hazards Analysis (PSHA). The PSHA result then overlaid with administration map and population data to obtain distribution and percentage of population threatened by the probabilistic earthquake hazard. The results showed the smallest value of ground acceleration located in the south-west (Tamalate sub district), further north increased and reached the highest value in the northeast (Biring Kanaya sub district). Both Tamalate and Biringkanaya can be classified as rural area with low population density. The urban area of Makassar, which is the concentration of population, located in the centre of Makassar, got the middle earthquake hazard.

Religious feelings in pre-school children in their own and their mothers’ perception
Authors: Tatala Małgorzata , Mańkowska Maria 
Published: January 2017

Abstract
The aim of the study was to compare the expression of religious feelings in pre-school children and the perception of these feelings by the children’s’ mothers. Ninety Polish children from Catholic families aged 4, 5 and 6 participated in the study. A picture method along with interviews with children’s mothers were employed to gather the data. Data from the two sources was compared, taking into consideration the content and ways of expression of the described feelings. Relations between positive and negative feelings were investigated and further statistical analyses were focused mainly on negative feelings. It was found that structure of negative religious feelings obtained directly from the children bears significant similarity to the mothers’ perception.

Published: January 2017

Abstract
This article explores the question, to what degree religiosity contributes, as a protecting factor against a broad category of socially deviant adolescent and youth behaviours. It also tests the hypothesis that gender plays a moderating role in the relationship between religiosity and problem behaviour. It employs a modified version of the Problem Behaviour Syndrome Measure (PBSM), in concert with Jessor and Jessor’s conceptual work. It also makes use of the Duke Religion Index (DUREL) to assess religiosity. The empirical study deals with a representative group of 960 students of upper-secondary schools in the Lubelskie province, Poland. The results were analyzed using canonical analysis and ANOVA. The achievements of the article are twofold. First, it identifies significant correlations between the different levels of religiosity among youth, and the occurrence and intensification of problem behaviours, particularly in regard to organized activity. Organized and intrinsic religiosity play principal protective roles, while the impact of personal religious practices is less significant. Secondly, while analyzing the moderating role of gender in the relationship between religiosity and the intensity of problem behaviour, it was found that gender does not have a significant interactive impact. An affirmative conclusion was confirmed in only two instances.
Faith and Belief, Importance, Community, Address in Care spiritual history tool by C. M. Puchalski as an instrument for an interdisciplinary team in patient car

Published: January 2017

Abstract
Being aware of the tradition of research on spirituality in theology and the existence of detailed publications and research concerning psychology of religion and religiosity in psychology as well as other sciences in Poland, the authors propose the recognition and adaptation of the FICA tool for spirituality research. The belief in the importance of deepening the knowledge and providing tools to research spirituality of human existence results from a long practice of the authors in palliative and hospital care. Understanding a difficulty in operationalizing the category of spirituality, they attempted at searching for a method that would be applicable to persons at the end of their lives as well as to all the suffering. Having analyzed the research tools built by Polish science as well as available ones on religiosity and spirituality the following paper aims at presenting the unknown FICA tool (F – Faith and Believe, I – Importance, C – Community, A – Address in Care) in Poland by Prof. Dr. Christina M. Puchalski, USA, being adapted to Polish practice. The tool presented allows for the evaluation of spiritual experience of persons taken medical and social care of by every member of multidisciplinary team of professionals. Since the FICA tool is a qualitative scale it does not need a normalization and standardization methodology. However, a cultural adaptation is crucial in order to make the practical tool become help in answering spiritual and existential questions posed by patients to workers and voluntaries engaged in the process of Care.
Une excursion entomologique à l'île de Quelpart (Cheju-do) et découverte d'une espèce nouvelle pour la Corée de Chrysolina Motschulky (Col. Chrysomelidae) . Réflexions sur la plantagophagie. (Suite et fin)
Authors: Jolivet Pierre 
Published: January 2017

Chrysolina staphylea, new species for Korea, living in the alpine region of Mont Halla, Quelpart island, South Korea, has been found inside and around the crater of the mountain. The host-plant is still unknown but in low altitudes the Plantago are perfectly accepted. The species seem to belong to a boreo-alpine group which has migrated possibly early pleistocene when there was a bridge linking the peninsula and Quelpart and when the temperature was low due to glaciations.
It is possible that similar or same species exist in other alpine zones in South Korea, such as Mont Giri (Chiri), Kyongsang Namdo, but probably not in North Korea which has been rather well prospected by the Japanese entomologists. C. staphylea has a wide holarctic distribution, including eastern Canada but the C. angusticollis complex, other cold dwelling group, is localized theoretically only in oriental Siberia, Hokkaido and Mandchuria. Ecology, habits and parasites of Chrysolina staphylea, as well as feeding preferences of the genus, are discussed thoroughly.
Contribution à l'étude des Blattaria de la Faune malgache. III. Genre Heminauphoeta Saussure et description de trois espèces nouvelles de Brachynauphoeta gen. nov
Authors: Van Herrewege Christian 
Published: January 2017

Brachynauphoeta, a new genus in the Oxyhaloidae familly (sensu Princis) was established for the brachypterous species which had been previously included in Heminauphoeta Saussure. Heminauphoeta includes two species (H. sakalava and H. picea). Brachynauphoeta includes the older species (hova, brunneriana and mayottensis ) in addition with three herewith described new ones : jeannineae, michelleae and foulpointeensis.
Lectotypes were selected for H. sakalava and B. hova (Saussure et Zehntner). The habitus of the different species was figured in the two genera so as the wing pattern of Brachynauphoeta, and the sub-genital plates, when known. The male genitalia were figured in five species in both genera. The shape and morphology of the R2 sclerite could have a phylogenetical interest whereas the tentatively introduction of the ratio between the lenght of L2vm and R2 shown an unexpected difference between the two genera. This is the first report in the Blattaria of the possible interest of the male genitalia at the generic rank.
Effet de l'hydratation et de l'obscurité prolongée sur les épidermes foliaires détachés. Variations du potentiel osmotique et de l'amidon dans les cellules stomatiques
Authors: Mouravieff Igor 
Published: January 2017

On a examiné le comportement des épidermes foliaires détachés de quatre espèces, placées sur l'eau à l'obscurité pour une durée allant jusqu'au stade pre-mortem.
Les épidermes des deux espèces hydrophiles ont bien supporté le contact prolongé avec l'eau. Le potentiel osmotique et l'adhérence protoplasme-membrane n'ont pas sensiblement varié aux termes des essais et même se sont renforcés. Par contre, les espèces terrestres ont accusé une diminution de ces caractères plasmiques. La teneur en amidon diminue graduellement dans les stomates et peut même disparaître entièrement. Une nouvelle synthèse de l'amidon à partir de métabolites intermédiaires est fortement réduite après un séjour prolongé sur l'eau, ce qui reflète une altération des mécanismes responsables. L'auteur discute ces résultats à la lumière des idées récentes sur l'état de l'eau dans le protoplasme.

Published: January 2017

Elargissant les tests classiques des mycologues utilisant des phénols simples comme révélateurs des activités lignivores des Hyménomycètes, les auteurs proposent la rutine (rhamnoglucosyl-3 quercétine) comme substrat complémentaire ; l'ensemble des résultats est traité par analyse factorielle des correspondances.
Une corrélation positive apparaît, d'une part entre la notion de pourriture blanche et la présence de polyphénol-oxydases (dont celles responsables de la destruction de la rutine), d'autre part entre la notion de pourriture rouge et divers types de substitution osidique de la quercétine.

Published: January 2017

SummaryBackground: Heroin addiction has a negative impact on cognitive functions, and even recovering addicts suffer from cognitive impairment. Recent approaches to cognitive intervention have been taking advantage of what new technologies have to offer.Objectives: We report a study testing the efficacy of a serious games approach using tablets to stimulate and rehabilitate cognitive functions in recovering addicts.Methods: A small-scale cognitive training program with serious games was run with a sample of 14 male heroin addicts undergoing a rehabilitation program.Results: We found consistent improvements in cognitive functioning between baseline and follow-up assessments for frontal lobe functions, verbal memory and sustained attention, as well as in some aspects of cognitive flexibility, decision-making and in depression levels. More than two thirds of patients in cognitive training had positive outcomes related to indicators of verbal memory cognitive flexibility, which contrasts to patients not in training, in which only one patient improved between baseline and follow-up.Conclusions: The results are promising but still require randomized control trials to determine the efficiency of this approach to cognitive rehabilitation programs for the cognitive recovery of heroin addicts.
