Localization on the palmar face of the hand of a Darier-Ferrand dermatofiborosarcoma. About a case
Authors: AI Razaka , Ramampisendrahova Jean Baptiste , HAS Rohimpitiavana , HJC Razafimahandry
Published: April 2021

Darier-Ferrand dermatofibrosarcoma is a rare but not exceptional malignant mesenchymal skin tumor, representing 0.1 % of malignant skin tumors. It is characterized by high recurrence, slow growth and low metastatic potential. Although several clinical cases of an unusual variant of Darier-Ferrand dermatofibrosarcoma have been reported in the literature, localization on the palmar face of the hand is not common. We report a case of Darier and Ferrand dermatofibrosarcoma at the level of the fourth commissure of the palm of the left hand in a 43- year-old young Malagasy adult treated by a large surgical excision with a healthy margin of two centimeters associated with adjuvant chemotherapy with Imatinib.

The research was conducted based on a questionnaire survey retrieving the knowledge gained through educational and training programs, the importance of this knowledge and its relevance to the skills required for further career pursuance. In parallel, analysis was done of various curricula offered by prominent educational institutions throughout Europe, in the context of or associated with transport interchanges. Findings indicated that there is significant deficiency of knowledge in the European policy on intermodal transportation, business models building and interchange design. Also, it was observed that there is an increasing requirement for gaining skills on sustainable development and transportation planning, decision making methodologies, data collection methods and utilization of big data for policy-making.
Mode choice behaviour of students, integrating residential location characteristics: a study from Kochi City, India
Authors: Krishnapriya M.G.
Published: April 2021

Mode choice decision of individuals plays a vital role in transportation planning. Individual travel behaviour models can be improved by extending the set of influencing variables used for modelling. In a developing country like India, students contribute a major share of total travel demand especially during morning and evening peak hours of traffic; whose individual travel characteristics are very less studied by transportation professionals. This paper presents exploratory and statistical analysis of mode choice behaviour of students in Kochi City, India. The socio-demographic characteristics, activity-travel behaviour as well as residential location characteristics of students during a usual working day is collected using activity-travel survey data, in Kochi Municipal Corporation. Preliminary analysis gives details on daily activity-travel pattern, mode choice preferences and other particulars of commuters in the study area. Statistical models were developed for understanding the factors affecting mode choice decision and separate mode choice models are also developed for different categories of students. Simulation of choice probabilities over different attributes is also done to identify the potential policy variables that can promote the use of sustainable modes.
Improving Business Processes Efficiency and Quality by Using BPMS

Published: April 2021

The tasks of economic growth is a priority for the BRICS countries.
It implies the rise of labor productivity. However, one should not expect that this growth will be achieved through the expanded use of information technologies. Labor productivity is not determined by the level of technology development or the equipment used. A high degree of automation does not guarantee
increase in productivity. The organization of production depends on both technical and governance factors. The latter t involves coordinated implementation
of various processes. It can be concluded that enterprises in the non-industrial sector and public administration should pay more attention to their business processes. The use of BPMS - process oriented IT systems can help these enterprises to increase their labor productivity, and the states to ensure sustainable economic growth.

Al hablar de la salud pública se enfatiza constantemente en la seguridad de los usuarios y la calidad de la asistencia médica ofrecida; en el marco de la medicina intensiva se atienden pacientes con enfermedades de naturaleza potencialmente letales, incluyendo aquellos con condiciones altamente inestables. Con el objetivo de indagar sobre la calidad del servicio a la población, factores de riesgos, cumplimiento de protocolos y manejo de normas de bioseguridad en las unidades de cuidados intensivos se realizó una revisión descriptiva de la producción científica durante el último quinquenio. Los estudios revelaron numerosos temas respecto a las infecciones nosocomiales, encontrando en menor medida artículos sobre aspectos éticos, cumplimiento de normativas y del entorno laboral, un importante porcentaje de los estudios insisten en el apoyo al paciente y sus familiares, siendo factores de salud pública de elevada preocupación social.
Developing middle school students’ English pronunciation using educational videos in the classroom
Authors: Reinoso Illescas Lorena , Heras Urgiles Esteban
Published: April 2021

This study examines the extent to which middle school students improved their pronunciation through the use of educational videos and what their perceptions were about this technique. The study was carried out at a public educational institution in Cuenca – Ecuador. Sixty-five ninth-graders participated: 33 students (15 boys and 18 girls) were part of the intervention group, and 32 students (15 boys and 17 girls) were part of the control group. The study used a mixed-method approach, so both quantitative and qualitative data were collected. The students took a pre- and a post-test based on a reading aloud activity to measure their level of pronunciation. Furthermore, at the end of the study, they were invited to complete a questionnaire with open-ended questions about the use of videos in class. During the ten weeks of the treatment, the intervention group received classes that included the regular use of videos, while the control group received their usual classes with the researcher; no videos were used at all. The final results showed that students’ perceptions in the intervention group regarding the use of videos in the class were mostly positive; they considered videos useful for the improvement of pronunciation because they heard the correct pronunciation and could observe facial movements, which helped to acquire better pronunciation. Further, the statistical analysis of the scores given in the pre- and post-test by both evaluators (researcher and inter-rater) showed that there was an improvement in the students’ pronunciation skills in the intervention group.

Authors: Perazzo Logioia Daniel Claudio , Jiménez González Ledys Lisbeth , Heras Jessenia
Published: April 2021

El análisis de la experiencia educativa en diferentes países por parte de la UNESCO sostiene que el éxito de la educación en línea en países como China, en el marco de la pandemia, se centró en los niveles de desarrollo tecnológico que caracterizaban al país asiático y la articulación oportuna entre el sistema de educación y desarrollo tecnológico. A diferencia de China, en la gran mayoría de los países de América Latina los bajos niveles de desarrollo de las nuevas tecnologías y las desigualdades sociales representan obstáculos determinantes para garantizar la continuidad de la educación. En el caso específico de Ecuador solo 37% de la población tiene acceso a internet, por lo cual garantizar el derecho inalienable a la educación presenta mayores dificultades en el contexto de emergencia nacional y el decreto de modalidad de teletrabajo en todos los niveles de educación como mecanismo para la prevención de contagios por la COVID-19. Este trabajo de investigación tiene como objetivo analizar las acciones que desde un enfoque psicológico, pedagógico y técnico- administrativo han garantizado el derecho a la educación. Empleando el método analítico-descriptivo se toma como referencia la experiencia del Instituto Superior Tecnológico Particular Sudamericano de la ciudad de Cuenca. Como resultado de la investigación se propone un conjunto de estrategias socio-pedagógicas para la retención estudiantil, así como lineamientos para la planificación de la virtualización de la educación en línea.

Published: April 2021

Currently, the English language has both an important role in university studies and professional careers. With that in mind, the present study employed an exploratory research approach to determine university students’ perceptions with regard to learning course content on curriculum and education-related topics through the implementation of content-based lessons taught in the English language. A survey was administered to 171 students in different majors from one public university in Ecuador. The close-ended questions focused on learning about the respondents’ perceptions concerning varied statements, such as the importance and suitability of the use of English for the learning-teaching process of university subjects, the helpfulness and impact of learning content through the implementation of class sessions taught in English. Furthermore, an open-ended question was put forward to find out in what ways the learning of university subjects taught in English may help the study participants in the future. The findings showed that a large number of respondents had positive attitudes towards learning content-based lessons about the education-related subject matter in English, as they found this instructional process helpful in terms of class participation, motivation, critical thinking, and other aspects. It was concluded that students could better learn the English language in a more genuine manner by means of lessons directed by CLIL, as they complete essential undergraduate courses from their field of study at the university level.

Con el propósito de realizar una revisión descriptiva de los estudios compilados enfocados a los factores de riesgos sociales para que se produzcan accidentes de tránsito con vehículos livianos, se ha ejecutado una búsqueda en diversas bases de datos electrónicas, para lo cual se emplearon los términos como: accidentes, factores sociales, vehículos, tránsito, así como, sus combinaciones. Los artículos analizados correspondieron a los últimos cinco años y los principales factores encontrados fueron: la falta de pericia de los conductores, el consumo de sustancias estupefacientes y bebidas alcohólicas, además, se encontraron autores que demuestran la incidencia del estado de ánimo, la distracción y el exceso de velocidad como causas de los accidentes. Se concluye puntualizando en la necesidad de políticas de formación educativa, capacitación a choferes e incrementar el control y la divulgación especializada en esta área, contribuyendo desde la sociedad al cumplimiento de las normativas de tránsito y la seguridad vial.
Salud y saberes en sistemas multiespaciales en la Huasteca Veracruzana
Authors: Reyes Fuentes Felipe , Llanos Hernández Luis , Hernandez Hernández Ameyali
Published: April 2021

En las comunidades rurales, sobre todo aquellas de ascendencia indígena, las plantas medicinales son un recurso importante para enfrentar los procesos de salud y enfermedad. Resulta relevante la aplicación terapéutica de la flora, pero lo es más el tejido sociocultural que descubrió su utilidad, que aplicó el intelecto sobre estos recursos y creó un sistema de curación. En este sentido, la investigación se centra en el estudio de las entidades vegetales articuladas con técnicas específicas que edifican el espacio social de la medicina tradicional. El concepto que articula metodológicamente la investigación es el espacio concebido, este como la noción indisoluble de sistemas de objetos y sistemas de acciones, mismo que es mediado por técnicas que reproducen una intencionalidad en contextos sociales específicos. Así, el trabajo analiza los espacios vinculados con la salud y los tratamientos populares generados en Ixcanelco, una comunidad nahua de la Huasteca Veracruzana. Los espacios terapéuticos identificados son multifuncionales, posibilitan la preservación de una cultura y de la flora curativa, asimismo funcionan como una tecnoestructura cognitiva para la generación de prácticas y saberes que integran el patrimonio biocultural de la Huasteca y de México. El método analítico permite conocer las partes y su interrelación que componen al espacio social, es un enfoque cualitativo que estudia la subjetividad de los actores, apoyándose en las entrevistas semi-estructuradas y descripciones de carácter etnográfico.
Globalización y (re)localización: Sus efectos en las sociedades rurales latinoamericanas
Authors: Hernández Flores José Álvaro
Published: April 2021

El fenómeno de globalización constituye un tópico ineludible en el análisis de las transformaciones socioeconómicas, políticas y culturales ocurridas durante las últimas décadas. Si bien se trata de un concepto que desde su surgimiento ha estado sujeto a una enorme diversidad de enfoques e interpretaciones, la mayoría de las acepciones tienden a destacar la dimensión homogeneizadora del fenómeno en detrimento de las secuelas diferenciadoras que derivan de su interacción con atributos muy concretos del territorio, tales como las características físico-naturales, el desarrollo de los procesos históricos y la asimilación del propio proceso por parte de los actores locales. El presente trabajo retoma las categorías conceptuales de “localización” y “relocalización” con el objetivo de analizar desde una perspectiva crítica la dinámica compleja a través de la cual los procesos globalizantes y localizantes interactúan para producir nuevas identidades, formas de organización, estrategias de vida, luchas por el espacio y poder, así como nuevos repertorios culturales y de conocimiento en el medio rural latinoamericano. A partir de una revisión documental se argumenta que los rasgos emergentes que caracterizan a las sociedades rurales contemporáneas, así como sus diversas y novedosas formas de organización, constituyen expresiones de dichos procesos.
"Trastes y herramientas". Significados del trabajo agrícola femenino y masculino en grupos domésticos de la Sierra de Zongolica
Authors: Vivar Arenas Josefina
Published: April 2021

Se reflexionó sobre las diversas formas con que hombres y mujeres construyen los significados del trabajo femenino y masculino a partir de los cambios productivos y laborales en Mexcala (municipio de Soledad Atzompa, Veracruz). Desde la década de los años setenta, esta localidad ha experimentado un proceso de reorganización del trabajo que significó el desplazamiento de la agricultura y la producción de artículos de raíz (escobetas y cepillos) en favor de la explotación forestal con fines artesanales. El argumento central es que la adopción de herramientas eléctricas parece reforzar los estereotipos que cruzan la división sexual del trabajo y los fortalecen: mujeres débiles, herramientas fáciles, hombres fuertes, herramientas pesadas y peligrosas.

E n este artículo se analiza el origen y desarrollo de procesos organizativos campesinos orientados hacia la producción de café orgánico y de comercio justo en la Reserva de la biósfera El Triunfo, Chiapas, México; así como los elementos que posibilitan su permanencia. Desde el constructivismo social, y haciendo uso de la metodología cualitativa, se examina la trayectoria de la organización campesina cafetalera CESMACH (Campesinos Ecológicos de la Sierra Madre de Chiapas, Sociedad Civil). Encontramos que el desarrollo y la permanencia de esta organización campesina están fundamentados en las subjetividades compartidas, acciones colectivas permanentes, normas propias, capacidades autogestivas y adaptativas, cadenas de valor apropiadas y en la redistribución de beneficios los cuales impactan en el cumplimiento de la visión, misión y principios tanto de la asociación campesina como los del área natural protegida. Se puede considerar como un caso excepcional, por el acompañamiento y recursos externos recibidos en sus inicios, pero sin crear dependencia.

Published: April 2021

Gran parte de la población mexicana ha depositado su confianza en el nuevo gobierno, que estará en funciones durante el periodo 2018-2024. Si se convence durante ese tiempo de los avances positivos de su programa, hay alta probabilidad de que el enfoque y la nueva forma de atacar los problemas socioeconómicos y políticos continúe por un plazo mayor a seis años. De aquí, el objetivo del trabajo: Analizar, desde el punto de vista económico, las probabilidades de éxito del gobierno actual, en la realización de su programa durante el sexenio. Se recurrió al análisis de los factores externos, así como a las acciones y resultados de los diversos actores que conforman e influyen en el ambiente económico del país; además se recurre al análisis macroeconómico de oferta y demanda global. Se concluye que se vislumbran posibles cambios significativos en el país en el mediano y largo plazo, pero en el corto plazo los cambios son bastante limitados. El éxito o fracaso del gobierno en turno es todavía incierto. El funcionamiento de los cambios propuestos y que están en ejecución, requieren tiempo de maduración en buena parte de ellos; otros de sus impactos ya empiezan a ser notorios.
La transformación del orden insurgente en el suroccidente colombiano, 2016-2020
Authors: Ángel Osario Julialba , Nieto Gómez Libia Esperanza , Sánchez Jiménez Wilson , Giraldo Díaz Reinaldo
Published: April 2021

La paz en Colombia se constituye en la mayor de las prioridades. La guerra y la presencia insurgente en varios territorios del país han creado un orden insurgente, un orden alternativo, en donde un conjunto de valores, instituciones y relacionamientos organizan la vida diaria de comunidades que, pese a la violencia estatal, subsisten y algunas, incluso, prosperan. En este documento se presentan los resultados de una investigación centrada en la transformación del orden insurgente en los Espacios Territoriales de Capacitación y Reincorporación –ETCR– del suroccidente colombiano: Tumaco y Policarpa en el departamento de Nariño; Caldono, Miranda y Buenos Aires, en el departamento del Cauca, y Planadas en el sur del Tolima. Particularmente, se develan los desenlaces del Acuerdo de Paz, firmado en 2016, a la luz pública de su implementación con enfoque territorial desde los propios escenarios del devenir de la vida cotidiana de los excombatientes. Para conseguir el objetivo de contribuir al fortalecimiento de políticas que sirvan para consolidar la construcción de paz en el período de postconflicto 2016-2020, se adoptó la metodología denominada “sociología visual”, la cual incluyó entrevistas, registros audiovisuales y fotografías. Los resultados dan cuenta del mundo cotidiano de la comunidad de excombatientes y de su voluntad para intentar un nuevo comienzo asociativo y territorial, después de haber transitado los caminos de la guerra.

Published: April 2021

En la actualidad es inminente la búsqueda de nuevos productos que sean elaborados a través de materiales reciclables para ayudar en la sustentabilidad para nuestro planeta. Este artículo busca contribuir a la creación de un panel desarrollado con materiales considerados desperdicios como lo son el aserrín y la fibra de coco. El primer material es utilizado en la industria de la construcción, y el segundo, es un desperdicio orgánico que, por lo general, tiramos a la basura. En el mercado existen paneles que tienen condiciones acústicas, pero en su mayoría no provienen del reciclaje, con esta innovación buscamos la creación de un panel con similares características a los tableros convencionales, pero sin que esto afecte el medio ambiente. Durante el proceso de fabricación del panel, experimentamos con varios productos aglomerantes, una vez concluidos los prototipos, realizamos los ensayos de flexión, compresión, acústicos, retención de humedad y resistencia al calor. Se obtuvo en dos paneles un comportamiento similar a los tableros MDF y el otro con el drywall utilizados en muros de interiores. Con los resultados obtenidos se espera incentivar a la industria de maderera para reciclar el aserrín, y al sector de la construcción, para la utilización de materiales más amigables a nuestro ecosistema.

Published: April 2021

O presente trabalho tem como objetivo analisar a percepção de famílias beneficiárias sobre o efeito do Programa para seu bem-estar e execução de atividades econômicas. Trata-se de uma pesquisa quantitativa que realizou a coleta de dados por meio de questionário aplicado para 36 beneficiários do Programa em nove comunidades dos Municípios de Lago do Junco e Lago dos Rodrigues, no Estado do Maranhão. A análise indica a importância do Programa para as famílias dos dois Municípios pesquisados, pois, colabora para o bem-estar das mesmas, o que se contrapõe aos argumentos de acomodação por parte dos beneficiários, pois, foi possível observar que dentre os entrevistados, as respostas mais frequentes indicam não haver diferença em suas atividades econômicas a partir do acesso ao Programa. É necessário observar a percepção dos beneficiários quanto o acesso ao Programa Bolsa Família, de forma para preencher a lacuna de trabalhos nessa área e contribuir para ações governamentais visando o aperfeiçoamento não só do Programa, mas de medidas que ofereçam melhores condições para as famílias rurais e não rurais que se encontram em situação de pobreza e extrema pobreza, para de fato superar a desigualdade social.
Forecasting and Identifying the Meteorological and Hydrological Conditions Favoring the Occurrence of Severe Hazes in Beijing and Shanghai using Deep Learning
Authors: Wang Chien
Published: April 2021

Abstract. Severe haze or low visibility event caused by abundant atmospheric aerosols has become a serious environmental issue in many countries. A framework based on deep convolutional neural networks has been developed to forecast the occurrence of such events in two Asian megacities: Beijing and Shanghai. Trained using time sequential regional maps of meteorological and hydrological variables alongside surface visibility data over the past 41 years, the machine has achieved a good overall accuracy in associating the haze events with favorite meteorological and hydrological conditions. Furthermore, an unsupervised cluster analysis using features with a greatly reduced dimensionality produced by the trained machine has, arguably for the first time, successfully categorized typical regional meteorological-hydrological regimes alongside local quantities associated with haze and non-haze events in the two targeted cities, providing substantial insights to advance our understandings of this environmental extreme.
Boundary layer water vapour statistics from high-spatial-resolution spaceborne imaging spectroscopy
Authors: Richardson Mark T. , Thompson David R. , Kurowski Marcin J. , Lebsock Matthew D.
Published: April 2021

Abstract. Daytime clear-sky total column water vapour (TCWV) is commonly retrieved from visible and shortwave infrared reflectance (VSWIR) measurements, and upcoming missions such as the Earth Surface Mineral Dust Source Investigation (EMIT) will offer unprecedented horizontal resolution of order 30–80 m. We provide evidence that for convective planetary boundary layers (PBLs), spatial variability in TCWV corresponds to variability in PBL water vapour. Using synthetic optimal estimation retrievals applied to Large Eddy Simulation (LES) output, we show that EMIT can retrieve horizontal variability in PBL water vapour, provided that the domain surface is uniformly composed of either vegetated surfaces or mineral surfaces. Random retrieval errors are easily quantified and removed, but biases from −7 % to +34 % remain in retrieved spatial standard deviation and are primarily related to the retrieval’s assumed atmospheric profiles. Future retrieval development could greatly mitigate these errors. Finally, we account for changing solar zenith angle (SZA) from 15–60° and show that the non-vertical solar path destroys the correspondence between footprint retrieved TCWV and the true TCWV directly above that footprint. Even at the 250 m horizontal resolution regularly obtained by current sensors, the derived maps correspond poorly to true TCWV at the pixel-scale, with r2 < 0.6 at SZA = 30°. However, the derived histograms of TCWV in an area are closely related to the true histograms of TCWV at the nominal footprint resolution. Upcoming VSWIR instruments, primarily targeting surface properties, can therefore offer new information on PBL water vapour spatial statistics to the atmospheric community.
Comparing scattering ratio products retrieved from ALADIN/Aeolus and CALIOP/CALIPSO observations: sensitivity, comparability, and temporal evolution
Authors: Feofilov Artem , Chepfer Hélène , Noel Vincent , Guzman Rodrigo , Gindre Cyprien , Chiriaco Marjolaine
Published: April 2021

Abstract. The spaceborne active sounders have been contributing invaluable vertically resolved information of atmospheric optical properties since the launch of CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) in 2006. To ensure the continuity of climate studies and monitoring the global changes, one has to understand the differences between lidars operating at different wavelengths, flying at different orbits, and utilizing different observation geometries, receiving paths, and detectors. In this article, we show the results of an intercomparison study of ALADIN (Atmospheric Laser Doppler INstrument) and CALIOP (Cloud-Aerosol Lidar with Orthogonal Polarization) lidars using their scattering ratio (SR) products for the period of 28/06/2019−31/12/2019. We suggest an optimal set of collocation criteria (Δdist < 1º; Δtime < 6 h), which would give a representative set of collocated profiles and we show that for such a pair of instruments the theoretically achievable cloud detection agreement for the data collocated with aforementioned criteria is 0.77 ± 0.17. The analysis of a collocated database consisting of ~78000 pairs of collocated nighttime SR profiles revealed the following: (a) in the cloud-free area, the agreement is good indicating low frequency of false positive cloud detections by both instruments; (b) the cloud detection agreement is better for the lower layers. Above ~7 km, the ALADIN product demonstrates lower sensitivity because of lower backscatter at 355 nm and because of lower signal-to-noise ratio; (c) in 50 % of the analyzed cases when ALADIN reported a low cloud not detected by CALIOP, the middle level cloud hindered the observations and perturbed the ALADIN’s retrieval indicating the need for quality flag refining for such scenarios; (d) large sensitivity to lower clouds leads to skewing the ALADIN’s cloud peaks down by ~0.5 ± 0.4 km, but this effect does not alter the polar stratospheric cloud peak heights; (e) temporal evolution of cloud agreement quality does not reveal any anomaly for the considered period, indicating that hot pixels and laser degradation effects in ALADIN have been mitigated at least down to the uncertainties in the following cloud detection agreement values: 61 ± 16 %, 34 ± 18 % 24 ± 10 %, 26 ± 10 %, and 22 ± 12 % at 0.75 km, 2.25 km, 6.75 km, 8.75 km, and 10.25 km, respectively.
A role for virtual outcrop models in blended learning – improved 3D thinking and positive perceptions of learning
Authors: Bond Clare E. , Cawood Adam J.
Published: April 2021

Abstract. Virtual outcrop models are increasingly used in geoscience education to
supplement field-based learning but their efficacy for teaching key 3D
spatial thinking skills has been little tested. With the rapid increase in
online digital learning resources and blended learning, most recently
because of the global COVID-19 pandemic, understanding the role of virtual
field environments in supporting and developing skills conventionally taught through field-based teaching has never been more critical. Here we show the efficacy of virtual outcrop models in improving 3D spatial thinking and provide evidence for positive perceptions amongst participants using virtual outcrops in teaching and learning. Our results show that, in a simple,
multiple-choice scenario, participants were more likely to choose the 3D
block diagram that best represents the structure when using a virtual
outcrop (59 %) compared to more traditional representations, such as a geological
map (50 %) or field photograph (40 %). We add depth to these results by
capturing the perceptions of a cohort of students, within our full
participant set, on the use of virtual outcrops for teaching and learning,
after accessing a virtual field site and outcrops which they had
previously visited during a day's field teaching. We also asked all participants if and how virtual outcrops could be used effectively for teaching and training, recording 87 % of positive responses. However, only 2 % of participants felt that virtual outcrops could potentially replace in-field teaching. We note that these positive findings signal significant potential
for the effective use of virtual outcrops in a blended learning environment and
for breaking barriers to increase the equality, diversity and inclusivity of geoscience field skills and teaching.

Abstract. Conservation tillage has attracted increasing attention over recent decades, mainly due to its benefits in improving soil organic matter content and reducing soil erosion. Under intensive conventional tillage systems, some studies have focused on the responses of soil properties in the topsoil to straw retention. However, long-term straw mulching effects on soil physicochemical properties and bacterial communities among different soil depths under a no-till system are still obscure. One twelve-year experiment was conducted that included straw removal (CK) and straw mulching (SM) treatments. Soil samples were collected at 0–5, 5–10, 10–20, and 20–30 cm soil depths. Most soil physicochemical properties and the relative abundances of bacterial phyla were varied with soil depth. Compared with CK, SM increased soil total nitrogen and organic carbon, available phosphorus and potassium, dissolved organic carbon and nitrogen, and water content. SM increased soil bacterial abundance but reduced the Shannon diversity of the bacterial community at 0–5 cm depth. SM increased the relative abundances of Proteobacteria, Bacteroidetes, and Acidobacteria but reduced those of Actinobacteria, Chloroflexi, and Cyanobacteria. SM had different effects on the relative abundances of some C- and N-cycling genera, for instance, increasing Rhodanobacter, Rhizomicrobium, and Terracidiphilus, and reducing Anaeromyxobacter, Mycobacterium, and Syntrophobacter. A principal coordinate analysis indicated that SM largely affected soil bacterial communities at topsoil depth. Soil pH and different nitrogen and organic carbon fractions were the major drivers shaping soil bacterial community. Overall, straw mulch is highly recommended for use under a no-till system because of its benefits to soil fertility and bacterial abundance. However, inorganic nitrogen fertilizer levels may be reduced under straw mulching to maintain or increase soil bacterial Shannon diversity in future studies.

Abstract. The endemic argan tree (Argania spinosa) populations in South Morocco are highly degraded due to overbrowsing, illegal firewood extraction and the expansion of intensive agriculture. Bare areas between the isolated trees increase due to limited regrowth, but show lower soil quality than their neighbouring tree areas. Hypothetically, spatial differences of soil quality of the intertree area should result from translocation of litter or soil particles (by runoff and erosion or wind drift) from canopy-covered areas to the intertree areas. 385 soil samples were taken around the tree from the trunk along the tree drip line (within and outside the tree area) as well as the intertree area between two trees in four directions (upslope, downslope and in both directions parallel to the slope) and analysed for soil moisture, pH, electrical conductivity, percolation stability, total nitrogen content, content of soil organic carbon and C / N ratio. 74 tension-disc infiltrometer experiments were performed near the tree drip line, within and outside the tree area, to measure the unsaturated hydraulic conductivity. We found that the tree influence on its surrounding intertree area is limited, with e.g., Corg- & N-content decreasing significantly from tree trunk to tree drip line. However, intertree areas near the tree drip line differed significantly from intertree areas between two trees, yet only with a small effect. Trends for spatial patterns could be found in eastern and downslope directions due to wind drift and slope wash. Soil moisture was highest in the north due to shade from the midday sun, the influence extended to the intertree areas. The unsaturated hydraulic conductivity also showed significant differences between areas within and outside the tree area near the tree drip line. Although only limited influence of the tree on its intertree area was found, the spatial pattern around the tree suggests that reforestation measures should be aimed around tree shelters in northern or eastern directions with higher soil moistures, N- or Corg-content to ensure seedling survival.

Reclamation of former mines hereinafter referred to as reclamation is an attempt to repair or reclaim land and vegetation in degraded forest areas as a result of mining and energy business activities in order to function optimally according to With the designation (Permenhut number: 146-Kpts-II-1999). Revegetation is a former mine. This activity is intended to restore, maintain and improve the functions of forests and land so that the carrying capacity, productivity, and role in supporting the life buffer system is maintained (anonymous, 2004).

The objectives of the study are to know the height and diameter growth of the Sengon (Paraserianthes falcataria), Sengon Buto (Enterolobium cyclocarpum), Johar (Cassea Siamea) and Trembesi (Samanea Saman) in flat areas and Area of the slope on a former mine and to find out if there is any difference in growth in both conditions of the area.

This research was conducted in PT. Khotai Makmur Insan Abadi (KMIA) in Separi village of Tenggarong Seberang district  from Kutai Kartanegara Regency for 3 months which is from October to December 2018 conducted in two conditions with the creation of plots namely on a flat area and slope area with a size of 20x20 m each two pieces plot. The research plots are placed intentionally (purposive) to be able to represent the desired location. The measurement of the diameter using phiband and height using the Clinometer is done on the tree that goes inside the plot. The measurement results are processed using simple statistics and to know the difference in the growth used t-test .

Based on the results of observation, collection and processing of data, it can be concluded that the plant growth of Sengon (Paraserianthes falcataria), Sengon Buto (Enterolobium cyclocarpum), Johar (Cassea siamea) and Trembesi (Samanea saman) that 3 years old on former land of PT. Khotai Makmur Insan Abadi (KMIA) in Separi village Tenggarong Seberang district the Regency of Kutai Kertanegara relatively equal.  Then based on the results of the t-test is obtained there is no difference in plant growth between the slope area and in the flat area. The advice that can be given from this research is the need to be diversified planting distances to get the closure of the ideal vegetation.

This research is motivated by the difficulty in determining the optimal number of human resources required. To be able to calculate HR requirements accurately, a device called a Workload Analysis (ABK) is needed. This study aims to analyze the operator's job description, an overview of the use of operator working time, and workload and needs. The method used is job description analysis, calculation of productive work time usage with work sampling method, and workload analysis using Full Time Equivalent (FTE) method based on work unit activity. The results of the workload analysis show that there are job descriptions that have not been listed in the written description of the company and there are still stations that have a written job description that does not match the work in the field. The percentage of productive working time for operators is between 42% and 77%, all of which are still low because they are below the standards set by the company, which is 85%. Calculation of the workload of the process part operator, obtained an FTE figure of 7.6 which means the optimal number of operators required by the process section is 8 people. This number is in accordance with the actual number in the process section, namely 8 people.
