PSYCHOLOGICAL ANALYSIS OF THE ADOPTION OF RISKY SEXUAL BEHAVIOR BY ADOLESCENTS IN TOGO
Authors: Hola AYEBOUA Folly
Published: July 2022

Adolescent sexual and reproductive health indicators are very worrying in sub-Saharan Africa. In Togo, for the 2020-2021 school year, 1,244 girls dropped out of school due to early pregnancy (Republic of Togo, 2022). This article aims to make a psychological analysis of the adoption of risky sexual behaviors of adolescents in Togo. To do this, we have conducted an exploratory study with five (05) adolescents received in psychological interview using the all-comers method. The results reveal that romantic attachment and sexual curiosity promote early sexuality. But sex education from parents delays the age of first sexual intercourse. With regard to multiple sexual partners, it is favored by low partner abandonment anxiety. For the non-systematic use of condoms, the reasons are diversified according to gender. Thus, for boys, strong sexual arousal contributes to non-systematic condom use, while girls explain it by strong abandonment anxiety. Furthermore, our results also reveal that the adoption of risky sexual behaviors has consequences on the psychological state of adolescents. Given the small size of our sample, it is necessary to conduct a study on a large population in order to identify the relevant psychological factors. This will enable an adolescent-centred approach to improve adolescent sexual health in sub-Saharan Africa.

Enhanced Prediction of Diseases in plants using Machine Learning and Climatology
Authors: L R Sujithra , V Priya
Published: July 2022

Automatic prediction of diseases in plants is a challenging task with technology intervention. In addition, proper maintenance of plant growth requires several steps, including research on environmental factors and management of water supply for proper plant growth. Traditional irrigation procedures stay inefficient additionally unpredictable. Every year, about 18% of the yield is lost to pests around the world. Identifying plant viruses remain the key to avoiding yield losses on agricultural products that are difficult to do manually. This paper presents an architecture that allows users to perform prediction of plant diseases using machine learning and climatology based data in real time, allowing farmers to view farm details automatically without manual intervention. Disease detection of visually visible symptoms of plants using image processing is proposed and treatment to reduce the level of damage is proposed to farmers. Therefore, the proposed system will increase productivity and benefit the irrigation sector. The main problem facing farmers in agriculture is the lack of water due to the effective irrigation separators on small farms. However, this technique consumes several weaknesses that can be improved, a method called the Automatic Irrigation System with weather forecasts for the efficient use of water resources. This overcomes the shortcomings of the AISPF process. The method uses available aquatic assets extra capacity by measuring atmospheric pressure, or barometric pressure (in inches), apart from measuring the water present-day in the topsoil and actually predicting the weather. This system uses a soil moisture sensor and a pneumatic sensor for performing measurements to be processed by the algorithm and water is discharged accordingly. This enables efficient use of water automatically. The system provides better accuracy than state of the art techniques for plant disease prediction and water flow control, which could be useful for irrigation.

Aim – to analyze methodological approaches to the functional zoning of the territory of agro-businesses on a landscape-ecological basis in the steppe zone of Kazakhstan for the purposes of land management. Methods – monographic, settlement-constructive, grouping, graphic modeling. Results – relevant problems of greening the land use of the republic, which needs to update the design methodology for the use and protection of agricultural land, taking into account the criteria for environmental protection, are shown. Typical objects are selected – agribusinesses of the steppe landscape zone, in which studies were carried out. An analysis of the resources of this area is given, ecological stability of agricultural landscape, an important component of which is erosion processes, is determined. Maps have been developed that characterize landscape and ecological features of a given area and are the basis for territorial zoning: a landscape hypothesis map with identification of elementary natural territorial complexes, a map of ecological stability of the territory and a map of the functional zoning of the area. The principles of agri-relief planning are justified, including the unification of morphological structural units of the landscape into a single land types in terms of ecological state and expediency of using land types with implementation of appropriate measures for each ecological landscape group. An experimental project has been developed in which a territorial organization is made on the example of economic entities of agricultural specialization in the steppe zone on ecological landscape substance. Conclusions – the basis for development of land management projects for agricultural structures should be a scientifically based system of organizational and economic measures for reconstruction of land area of agricultural enterprises on a landscape basis, which implies the design of environmentally sustainable and costeffective forms of land management.

Methods – quantitative and effective indicators are obtained on the basis of observation and collection of facts, comparative analysis and synthesis, and a systematic approach. Results – directions and main tasks of expanding cooperative relations in agricultural sector of the republic, the role of cooperation in providing conditions for unification of agricultural producers who have set themselves the goal of improving their economic and social situation; distribution of cooperative entrepreneurship; implementation of the social function through creation of jobs, guaranteed level of income; reducing the dependence of the domestic market on external factors; protecting the interests of economic entities; providing the population with the opportunity to purchase high-quality and relatively cheap goods. Conclusions – the author notes that it is necessary to implement new effective programs on creation of agricultural cooperatives at the state and local levels; using their capabilities in establishing an effective supply chain to the end consumer. Cooperation acts as one of the stabilizers of market economy, maintaining social balance, and serves as the basis for organizational and structural restructuring of agricultural production. In market economy, the activities of cooperating farms largely depend on their relationships with other branches of agriculture, which provide them with material and technical means and services, provide processing of their products, and sell them. As the experience of developed countries shows, the potential of agricultural cooperation contributes to the sustainable and balanced development of agricultural sector and ensuring food security.

Significant changes in the conceptual-normative framework of prison, as well as in the context of the necessary standards relevant to the practice of its execution, have not eliminated the "basically negative" consequences of imprisonment. While today alternative, non-institutional criminal sanctions and measures are the standard in almost all modern criminal justice systems, their application in practice is very different both in terms of scope and in terms of efficiency. The concept of applying alternative sanctions and measures is fundamentally different from the application of imprisonment measures and requires a different, non-punitive approach and specially organized services. Essentially, the scope and efficiency of the application of alternative sanctions and measures depends on how functional the normative frameworks of each envisaged sanction and measure are and how operative and efficient are the services competent for their execution. The paper critically analyzes the conditions and manner of work of the domestic commissioners` service in the context of the fact that the implementation of non - institutional measures in domestic conditions is progressing but still very slow. The wider application of non- institutional measures and sanctions is slowed down by the insufficiently precise normative framework of certain probation measures, as well as certain organizational weaknesses of the commissioners` service.

The intention is to briefly present legal base, modus, and possibilities of usage of the part of the European continent covered with rivers according to criminal law perspective. We can see that this legal field and these areas of economic potential which are impossible to control and supervise all time, have no adequate attention. A man had always tried to discover new countries by overcoming water ways and to earn. A man had success often, but sometimes he was destroyed by water, and he was unconsciousness of possibilities that he did not use. There is need for using water surface in a way that we satisfy our human needs, but without breaching norms of Criminal Law. There is ever present challenge for humankind how to protect environment from ourselves.

Due to the fact that all modes of traffic contribute significantly to pollution, road traffic is often at the top of the list. In accordance with the "polluter pays" principle, the application of economic instruments for environmental protection seeks to act in such a way as to encourage the behavior of economic entities in the direction of reducing pollution within the market. The range of these instruments is wide - from the so-called environmental taxes and fees, through subsidies to other incentives. Although it is widely believed that economic instruments are more efficient than administrative ones, in practice they are most often used in parallel and in combination. The answer to the question of whether a certain economic instrument will work purposefully will depend primarily on whether the application of that instrument satisfies its stimulating role.

Published: July 2022

DAS Bengkulu mengalami kejadian banjir setidaknya 2 kali dalam setahun pada musim hujan. Banjir merupakan salah satu bencana hidrometeorologi yang dipengaruhi oleh karakteristik fisik dan meteorologi DAS tersebut. Karakteristik tersebut merupakan dasar untuk melakukan perencanaan maupun pengelolaan di DAS tersebut. Oleh karena itu, penelitian ini bertujuan untuk menganalisis karakteristik fisik dan karakteristik meteorologi DAS Bengkulu, sebagai dasar untuk melakukan perencanaan maupun pengelolaan DAS, sehingga dapat meminimalisir kejadian maupun dampak dari bencana hidrometeorologi di DAS tersebut. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kuantitatif terhadap data karakteristik fisik dan meteorologi DAS Bengkulu. Karakteristik fisik DAS yang dianalisis yaitu morfometri, topografi, jenis tanah, dan penggunaan lahan di DAS Bengkulu. Sedangkan karakteristik meteorologi yang dianalisis yaitu curah hujan dan suhu udara di DAS Bengkulu. Hasil menunjukkan bahwa karakteristik fisik DAS Bengkulu mempunyai kemampuan menyimpan air yang rendah, sehingga infiltrasi kecil, namun laju limpasan kecil dan tipe pengaliran aliran sedang. Akan tetapi limpasan cenderung meningkat. Hal tersebut disebabkan oleh perubahan penggunaan lahan hutan yang semakin berkurang, didukung oleh curah hujan yang semakin meningkat, dan variasi suhu udara yang kecil.
Pengaruh Seruakan Dingin Asia Terhadap Tinggi Gelombang Maksimum di Selat Karimata dan Laut Jawa
Authors: Setiawan Budi
Published: July 2022

Indonesia merupakan negara kepulauan di daerah tropis dengan 2 (dua) musim (hujan dan kemarau), yang sebagian besar daerahnya merupakan daerah lautan. Musim di Indonesia sangat dipengaruhi oleh aktivitas monsun dingin Asia Timur yang juga memberikan pengaruh terhadap munculnya aktivitas seruakan dingin Asia yang membawa massa udara dingin dari belahan bumi utara ke belahan bumi selatan melewati daerah kepulauan maritim (cross equatorial flow). Kondisi ini kemudian menyebabkan terbentuknya awan – awan hujan yang merata dengan durasi yang cukup lama di daerah tersebut. Selain berdampak pada meningkatnya intensitas dan durasi hujan, seruakan dingin Asia diduga kuat juga memberikan dampak terhadap peningkatan tinggi gelombang di daerah tersebut. Hal ini dikarenakan pergerakan angin dominan yang bertiup cukup lama sehingga meningkatkan ketinggian gelombang, terutama di Selat Karimata dan Laut Jawa.

Dalam penelitian ini dianggap perlu untuk mencari hubungan antara seruakan dingin Asia dengan peningkatan tinggi gelombang, dalam hal ini di Selat Karimata dan Laut Jawa. Pendekatan yang digunakan adalah pendekatan sebab akibat, guna memperoleh gambaran mengenai akibat yang ditimbulkan oleh seruakan dingin terhadap kenaikan tinggi gelombang maksimum. Terdapat jeda waktu antara meningkatnya aktivitas seruakan dingin Asia di Laut Cina Selatan dengan meningkatnya tinggi gelombang di Selat Karimata dan Laut Jawa, sehingga dapat dilakukan antisipasi dini dampak gelombang tinggi yang ditimbulkan. Akhirnya hasil yang diharapkan dalam penelitian ini diharapkan mampu menjadi pengetahuan baru dalam melakukan prediksi tinggi gelombang di Selat Karimata dan Laut Jawa ketika terjadi seruakan dingin Asia.

Authors: YADAV SUBHASH KUMAR , ZAMAN TOLGA , KHOKHAR ANKIT , SAHA SUDIPTA
Published: July 2022

The present manuscript deals with the enhanced estimation of population mean using the known negatively correlated auxiliary variable. We introduce a naïve class of product type estimators of population variance utilizing known auxiliary parameters. The expressions for the bias and the mean squared error (MSE) of the proposed family of estimators are retained up to the first order of approximation. The optimal values of the characterizing constants are obtained by the method of Maxima-Minima. The least value of MSE of the introduced class is obtained for these optimal values of the constants. The suggested family of estimators is compared with the competing product estimators of the population mean. The efficiency conditions are also obtained and these are verified through the real data set. The estimators with the lesser MSE are recommended for the practical utility in different areas of applications.

Este trabajo tiene por objetivo el análisis de la calidad del agua del arroyo Langueyú para determinar el estado de situación y su relación con la gestión de los recursos hídricos superficiales a nivel local. Se tuvieron en cuenta antecedentes hidrológicos regionales. Se efectuaron recorridos siguiendo el cauce del arroyo desde la cuenca alta, al Sur de la ciudad de Tandil incluyendo sus tributarios Blanco y Del Fuerte, hasta la intersección con la Ruta Provincial Nº 30. Se seleccionaron 9 sitios en los que se realizaron muestreos de calidad de agua en el período 2009-2011. Se complementó el estudio con un ensayo ecotoxicológico referido al desarrollo y crecimiento de bulbos de cebolla y de peces. Además, se identificaron los usos del suelo lindantes al cauce y sus afectaciones. Se detectó que los efluentes de impacto en el recurso son en su mayoría las descargas provenientes de las plantas de tratamiento de aguas residuales de Obras Sanitarias de Tandil (OST) y de las industrias alimenticias. Los resultados revelan un aumento significativo de los parámetros físicoquímicos en agua a partir de la descarga de una de las plantas de OST. Se detectó la inhibición en el crecimiento de las raíces de las cebollas y una disminución en el porcentaje de sobrevivencia en peces en los puntos de descarga. Los resultados microbiológicos y la materia orgánica, medida a través de DBO5 y DQO, denotan el impacto de la descarga cloacal. Se propone a futuro el monitoreo y análisis detallado del agua del arroyo y de los distintos efluentes antrópicos.

 

Abstract

This work aims to analyze water quality of Langueyú stream, in order to determine its state and relationship with surface water management at local level. Regional previous studies were taken into account. Several itineraries were done along Langueyú stream channel, since the high part of the basin at the south, to the Provincial Route Nº 30 at the north. Two tributary streams were included, called Blanco and Del Fuerte. During the period 2009-2011, water quality sampling was executed in 9 selected places. An ecotoxicological test was done using onion bulbs and fish, in order to evaluate their development and growth. Besides, land uses near the stream and their impacts on water were identified. The main impact on surface water is caused by discharges from waste water treatment plants belonging to Obras Sanitarias Tandil (OST) and by food industries. Results show a significant increasing of physicochemical water parameters starting from one of the treatment plants. Growth inhibition in onions roots and decreasing in survival percentage of fish were detected in discharge points. Microbiological results together with DBO5 y DQO show the impact of waste water discharge. Detailed monitoring and analysis of Langueyú stream water and human discharges is recommended.

Published: July 2022

Las áreas mineras abandonadas comprenden yacimientos, instalaciones, residuos, maquinarias, etc. Es posible que estos sitios puedan ser reutilizados para uso recreativo y turístico.

La metodología de evaluación de la capacidad de acogida del territorio, aporta a la planificación de los usos y la gestión integrada. En los procesos de reutilización de dichas áreas, es necesario determinar la aptitud, vulnerabilidad, fragilidad y rasgos que permitan establecer intervenciones adecuadas.

El cese de la explotación de granito en Tandil, es el producto de varios hechos: la finalización de los permisos de explotación, la disminución de rentabilidad y la presión  de la sociedad local.  Como resultado han quedado taludes, depósitos, maquinarias y edificios en estado de abandono, y en conjunto paisajes degradados.

El uso recreativo planificado, daría a estos sitios un nuevo rol, según la capacidad del lugar para recibir usos hipotéticos. Este trabajo analiza las potencialidades para el desarrollo de actividades educativo-recreativas en una cantera de granito inactiva (Cantera Interlen) ubicada en el área periurbana de Tandil.

The methodology for the assessment of the capacity of reception of the territory, it brings to the planning of the uses and integrated management. In the processes of re-use of these areas, it´s necessary to determine the suitability, vulnerability, fragility and traits that allow them to establish appropriate interventions.

Stopping the exploitation of granite in Tandil, is the product of several facts: the end of operating permits, the drop in profitability and the pressure of the local society. As a result have been slopes, cavas, deposits, machinery and buildings in a state of abandonment, and in whole degraded landscapes.

The recreational use planned, would give these sites a new role, depending on the capability of the place to receive hypothetical uses. This paper analyzes the potential for the development of educational and recreational activities in a granite quarry inactive (Interlen Cantera) located in the periurban area of Tandil.

La biodiversidad de Cuba se caracteriza por notables valores de su medio natural, gran diversidad de ecosistemas y el alto grado de endemismo de sus recursos. Sin embargo, la misma ha declinado en diferentes regiones, lo que se evidencia notablemente en territorios ocupados por asentamientos poblacionales. Para mitigar esta problemática se necesita incentivar, en la sociedad cubana, la Educación Ambiental. A partir de ese interés, este artículo presenta un diagnóstico de la Educación Ambiental Comunitaria para la conservación de la biodiversidad, con énfasis en el cuabal, en los pobladores del Callejón de los Patos, de Santa Clara. La perspectiva metodológica que predominó, en la investigación, fue la cualitativa y se incorporó el análisis cuantitativo de los datos para visualizar mejor la tendencia en el análisis de resultados. Los métodos investigativos empleados fueron: la observación, entrevistas en profundidad y estructuradas. Los resultados del diagnóstico evidenciaron insuficientes conocimientos, en los pobladores, relacionados con la biodiversidad, el cuabal como elemento destacado de la misma en la zona, su conservación e importancia. Se detectó ausencia de proyección colectiva de acciones para mitigar los problemas ambientales identificados en el asentamiento.

 

Abstract

Cuba's biodiversity is characterized by remarkable values of its natural environment, great diversity of ecosystems and the high degree of endemism of its resources. However, it has declined in different regions, which is notably evident in territories occupied by population settlements. To mitigate this problem, it is necessary to encourage Environmental Education in Cuban society. Based on this interest, this article presents a diagnosis of Community Environmental Education for the conservation of biodiversity, with emphasis on the cuabal, in the inhabitants of Callejón de los Patos, in Santa Clara. The methodological perspective that predominated, in the research, was the qualitative one and the quantitative analysis of the data was incorporated to better visualize the trend in the analysis of results. The investigative methods used were: observation, in-depth and structured interviews. The results of the diagnosis showed insufficient knowledge, in the inhabitants, related to biodiversity, the cuabal as a prominent element of it in the area, its conservation and importance. There was a lack of collective projection of actions to mitigate the environmental problems identified in the settlement.

El indicador de la huella hídrica mide el volumen de agua consumida o contaminada en un proceso productivo y resulta útil para evaluar la sustentabilidad de dicha producción. Este trabajo tiene como objetivo calcular la huella hídrica verde y azul de la leche y el queso elaborados en un tambo-fábrica de Tandil, Argentina. El estudio se realizó en un establecimiento educativo agroindustrial que cuenta con diversos sectores de producción donde los estudiantes realizan sus prácticas formativas. Se analizaron los componentes de la huella hídrica considerando: el agua contenida en el alimento, la bebida animal y el agua de servicios. Los resultados indicaron que el volumen de agua consumido para la elaboración de 1 kg de queso es 10 veces mayor que para 1 kg de leche. La mayor proporción de la huella hídrica la representó el agua verde del alimento. Dentro de la huella azul de la leche, predominó la bebida animal sobre el agua de servicios, mientras que sucedió lo inverso en cuanto a la huella azul del queso. La reutilización del agua de refrescado de la leche para la limpieza del tambo impacta positivamente en la reducción de la huella azul. Se evidencia la necesidad de implementar medidas de reducción de consumos de agua azul, especialmente en la fabricación de quesos.

Abstract

The water footprint indicator measures the volume of water consumed or polluted during a productive process and it is useful to evaluate the sustainability of the production. This work aims to calculate the green and blue water footprint of milk and cheese made in a dairy farm combined with a cheese factory in Tandil, Argentina. The study was carried out in an educational and agro-industrial institution which has several productive sectors where students develop their training practices. The water footprint components of an animal product were analyzed: water related to feed, drinking water and services water consumption. The results showed that the volume of water consumed to make 1 kg of cheese was 10 times higher than the volume needed to produce 1 kg of milk. The main proportion of the water footprint was given by the green water related to feed. As regard to the blue water footprint of milk, animal drinking water was predominant over services water consumption, while the opposite happened with the blue water of cheese. The reuse of milk cooling water for cleaning the dairy farm positively impacts on blue water reduction. It is necessary to implement measures to reduce the blue water consumption mainly in cheese production.
