QR Based Despeckling Approach for Medical Ultrasound Images
Authors: Al-Asad Jawad Fawaz , Khan Adil Humayun , Latif Ghazanfar , Hajji Wadii
Published: August 2018

Background:

An approach based on QR decomposition, to remove speckle noise from
medical ultrasound images, is presented in this paper.

Methods:

The speckle noisy image is segmented into small overlapping blocks. A global covariance matrix is calculated by averaging the corresponding covariances of the blocks. QR decomposition is applied to the global covariance matrix. To filter out speckle noise, the first subset of orthogonal vectors of the Q matrix is projected onto the signal subspace. The proposed approach is
compared with five benchmark techniques; Homomorphic Wavelet Despeckling (HWDS), Speckle Reducing Anisotropic Diffusion (SRAD), Frost, Kuan and Probabilistic Non-Local Mean
(PNLM).

Results and Conclusion:

When applied to different simulated and real ultrasound images, the QR
based approach has secured maximum despeckling performance while maintaining optimal resolution and edge detection, and that is regardless of image size or nature of speckle; fine or rough.
Exploring the Effect of Buffer Strength on the Retention Time of Weak Acids, Neutral and Weak Bases in Hydrophilic Interaction Liquid Chromatography (HILIC) Mode
Authors: Al-Tannak Naser F. , Bawazeer Sami , Watson David G.
Published: August 2018

Background:

Hydrophilic Interaction Liquid Chromatography (HILIC) orthogonal to conventional
reversed phase High-Performance Liquid Chromatography (HPLC) mode allowing separation
of polar compounds. HILIC has been reported to be an alternative to normal phase liquid chromatography,
yet the separation mechanism reported in HILIC is much more complicated than that in
normal phase liquid chromatography.

Objective:

To investigate the effect of water layer thickness on silica gel and the amount of ammonium
ions present within the buffer on retention mechanism in hydrophilic interaction chromatography.

Methodology:

A test system was designed which used weak acids, neutrals and weak bases as probes
with three different strengths (5, 10 and 20 mM) of ammonium acetate, ammonium formate and ammonium
propionate as the counter-ions to compete with the test probes with ionised silanol groups and
water present in the stationary phase. A Kromasil 60-5SIL column (150 mm×4.6 mm×4 μm, pore size
60Å) was used as the stationary phase to perform the study.

Results:

Retention times were examined for the test probes at 90% acetonitrile (ACN) with 10% of 5,
10 and 20 mM of ammonium acetate, ammonium formate and ammonium propionate. As the buffer
strength increases, the thickness of the water layer on the surface of the silica gel increases and also
the repulsion between ionized silanol groups and acidic test probes will decrease. On the other hand,
such increase in buffer strength will increase the competition between the ammonium ions and basic
test probes. In addition, the hydration energy of buffer’s counter ions and hydrophilicity may be important
in retention mechanism in HILIC mode.

Conclusion:

At 20 mM buffer strength acidic probes with low log P values retain more due to reduced
repulsion by silanol groups, while basic probes retention time will decrease due to increased competition
from ammonium counter ions. However, in 5 mM buffer strength basic probes with low logP value
will be retained longer, while acidic probes will be eluted earlier due to the repulsion between ionized
acids and ionized silanol groups.

Background:

The high molecular weight and increasing lipophilicity drug face many problems starting from the drug development to formulation and conduction of pharmacological, toxicological and pharmacokinetic studies to its biological application. To overcome this problem, a different formulation of nano-sized drugs was developed recently. The use of Solid lipid nanoparticles (SLNs) and Nanostructured lipid carriers (NLCs) offers new insight into the formulation of the poorly soluble drug.

Objective:

The study aimed to investigate the literature with regard to the development of SLNs and NLCs for lipid-based nano drug delivery of poorly soluble drugs, with a view to identifying the factors influencing the optimization of the formulation of SLNs and NLCs and strategies to decrease the use of organic solvent during the preparation.

Results:

This review highlights the simple and easily scaled-up novel lipid nanoparticles (SLNs and NLCs) and their factors to be considered in the formulation for the proper selection of excipients. Also, this review summarizes the research findings reported by the different researchers regarding the principle formulation components, different preparation techniques, characterization, and toxicology of lipid nanoparticles.

Conclusion:

The SLNs/NLCs make this drug delivery system as one of the promising delivery systems, and safe colloidal lipid carriers for the delivery of poorly soluble drug and will be a solution to the formulation scientist for the solubility and permeability problem associated with the drugs to assure its good bioavailability.

Authors: Ghosh Ashmita , Khanra Saumyakanti , Haldar Gopinath , Bhowmick Tridib Kumar , Gayen Kalyan
Published: August 2018

Background: :

North east region of India is well known as biodiversity hotspot with endemic flora and fauna. Organisms belonging to the cyanobacterial species are commonly known as blue green algae and are found in diverse categories in the environment of north-east India. Potentials of these cyanobacterial species are mostly unexplored. Present study aimed to isolate, identify and evaluate the potential cyanobacterial strains for the sustainable producers of biomolecules with agricultural, therapeutic and industrial significance.

Methods::

Growth and biochemical characterization were performed with the isolated cyanobacterial species to investigate the growth kinetics, cellular pigments (carotenoid, phycobiliprotein and chlorophyll), protein, carbohydrate and lipid content.

Results::

Three Phormidium sp., one Oscillatoria sp., and one Microcoleus sp. were isolated from the Tripura state (North-east region of India). Results revealed that isolated Oscillatoria sp. has high lipid (~20%), protein (~40%), and carbohydrate (~30%) yield. Further, two isolated Phormidium sp., produced significant amount of carotenoids (~23 mg/gm dry biomass), phycobiliprotein (~20-25%) and high protein (~55%). Microcoleus sp. produced 62% carbohydrate and 20% phycobiliprotein with significant amount of carotenoids (~17 mg/gm dry biomass).

Conclusion::

Isolated Oscillatoria sp. is the promising resource for lipid and nutritional supplement due to high accumulated primary metabolites. Two Phormidium sp., can be used as animal and human nutritional food supplement and also can be further investigated for pigment production at industrial scale. Isolated Microcoleus sp. is the potential resource of carbohydrate and pigment. Isolated cyanobacterial strains are identified as viable candidates for the industrial production of biomass as well as other value added biomolecules.

Developing and supporting quality nursery facilities and staff are necessary to meet global forest and landscape restoration needs
Authors: Haase Diane L , Davis Anthony S
Published: August 2018

Seedlings are the foundation for many terrestrial ecosystems and are a critical consideration and investment for implementing global forest and landscape restoration programs. Global leaders have pledged to restore millions of hectares during the next decade, necessitating many millions of established plants. Although natural regeneration and direct seeding will likely meet a portion of that need, large quantities of high-quality, nursery-grown seedlings are also required. Insufficient plant quantities or poor-quality plants result in unsuccessful outplanting programs. Such failures have considerable economic and environmental consequences and will result in an inability to meet restoration goals. Nonetheless, the importance of restoration nurseries is often overlooked when making large-scale restoration commitments. Technology already exists to produce high-quality plants to meet a variety of goals. This technology cannot be applied, however, unless adequate resources and training are made available by overcoming political and socioeconomic barriers. In this article, we discuss the important role of nurseries to meet global restoration commitments and review three case studies where increased support to nursery programs resulted in improved restoration success.
Direct Seeding in Reforestation – A Field Performance Review
Authors: Grossnickle Steven C , Ivetić Vladan
Published: August 2018

Direct seeding has been considered a forest restoration option for centuries. Over the past half century, the use of this practice has declined in developed countries as forest regeneration programs have advanced with the production of quality seedlings that can successfully establish restoration sites. Direct seeding is being reconsidered as a restoration option as the potential size of the worldwide forest restoration program has grown because of massive deforestation in third-world nations and due to global climate change. This review examines direct seeding from a number of perspectives. First, merits of using this practice in restoration programs are defined. Major merits of this option are that it can be done quickly, over hard to reach and large disturbed areas, and at a relatively low cost. Second, current research findings from restoration programs are discussed. The major finding is that seedling establishment rates are low (i.e. typically around 20% of seeds planted) due to site conditions, seed predation and vegetation competition, and field performance (i.e. survival and growth) is lower than planted seedlings. Third, operational practices for the application in restoration programs are reviewed. To successfully conduct direct seeding programs practitioners need to consider seedbed receptivity, seed distribution and seeding rate. Fourth, potential new practices are presented. Some of these new practices attempt to create a more effective means to disperse seed across the site, minimize seed predation or create a more favorable microsite environment. This review provides a synthesis of what is known about direct seeding, thereby allowing practitioners to make a rational decision of whether to apply this practice towards their forest restoration program.

Authors: Carvalho Victor Miguel Barros de , Guimarães Patrícia Borba Vilar , Oliveira Adriana Carla Silva de
Published: August 2018

O presente artigo analisa as disposições constantes no Decreto 8.771/2016 sobre a regulação da monetização dos dados pessoais no âmbito da internet. Num mundo cada vez mais conectado e interligado, com enorme produção de dados e informações – mormente de dados pessoais – muitos agentes econômicos passaram a utilizar tais dados como insumos em seus modelos de negócio. Neste cenário, promulgouse a Lei nº 12.965/2014, o Marco Civil da Internet. Tal diploma previu certos direitos e garantias aos usuários da rede mundial de computadores – como o direito à inviolabilidade da privacidade e intimidade e a proteção dos dados pessoais. Todavia, algumas de suas disposições demandaram regulamentação e, neste escopo, editou-se o Decreto 8.771/2016, que trata, entre outros assuntos, da previsão de atuação regulatória do poder público sobre atividades relacionadas aos dados pessoais. Sobre estas disposições é que o presente artigo se debruçou. Como metodologia, analisou as determinações do Decreto em conjunto com as do Marco Civil, de normas relacionadas e posicionamentos doutrinários acerca do tema, deles procurando extrair diretivas regulatórias da monetização de dados. Teve como objetivo específico aferir a competência para editar atos que regulem atividades relacionadas aos dados pessoais. Entre os resultados, encontrou que certos dispositivos restaram imprecisos na distribuição de competências, e que os entes arrolados pelo legislador não são inteiramente competentes para regular o tema em fito. Concluiu que, apesar desta lacuna legal, os dados pessoais contam com certa proteção da lei, sugerindo, ainda, pela criação de ente regulador próprio e competente para regular esta matéria.

Published: August 2018

A presente pesquisa visa indagar se o sistema jurídico de patentes é efetivo o suficiente, no que diz respeito à sua aspiração moral, para incentivar o desenvolvimento de produtos de saúde, tendo por foco a análise dos depósitos de patentes para a doença de Chagas. A análise metodológica utilizada consiste numa abordagem qualitativa dos dados coletados de fontes diretas e indiretas, dentre as quais o site do Instituto Nacional da Propriedade Industrial. A partir dos dados coletados foram construídas três tabelas, as quais se referem ao número de depósitos relacionados à doença, o número de depósitos por depositante e o perfil funcional dos depósitos. Este estudo se baseia no marco teórico da luta pelo reconhecimento, de Axel Honneth, conjugado com o viver plenamente a lei, de Zenon Bankowski. A partir dos dados coletados relativos a doença de Chagas, infere-se a pouca efetividade do sistema jurídico de patentes com relação ao incentivo à inovação voltada para interesses sociais locais. Os interesses de mercado se sobrepõem à promessa vaga do sistema jurídico de patentes concernente à busca pelo desenvolvimento científico e tecnológico ancorado nos interesses sociais.

Published: August 2018

BACKGROUND

Routinely recorded electronic health records (EHRs) from general practitioners (GPs) are increasingly available and provide valuable data for estimating incidence and prevalence rates of diseases in the population. This paper describes how we developed an algorithm to construct episodes of illness based on EHR data to calculate morbidity rates.

OBJECTIVE

The goal of the research was to develop a simple and uniform algorithm to construct episodes of illness based on electronic health record data and develop a method to calculate morbidity rates based on these episodes of illness.

METHODS

The algorithm was developed in discussion rounds with two expert groups and tested with data from the Netherlands Institute for Health Services Research Primary Care Database, which consisted of a representative sample of 219 general practices covering a total population of 867,140 listed patients in 2012.

RESULTS

All 685 symptoms and diseases in the International Classification of Primary Care version 1 were categorized as acute symptoms and diseases, long-lasting reversible diseases, or chronic diseases. For the nonchronic diseases, a contact-free interval (the period in which it is likely that a patient will visit the GP again if a medical complaint persists) was defined. The constructed episode of illness starts with the date of diagnosis and ends at the time of the last encounter plus half of the duration of the contact-free interval. Chronic diseases were considered irreversible and for these diseases no contact-free interval was needed.

CONCLUSIONS

An algorithm was developed to construct episodes of illness based on routinely recorded EHR data to estimate morbidity rates. The algorithm constitutes a simple and uniform way of using EHR data and can easily be applied in other registries.
Technology-Based Interventions, Assessments, and Solutions for Safe Driving Training for Adolescents: Rapid Review (Preprint)
Authors: Sezgin Emre , Lin Simon
Published: August 2018

BACKGROUND

Safe driving training for adolescents aims to prevent injury and promote their well-being. In that regard, information and communication technologies have been used to understand adolescent driving behavior and develop interventions.

OBJECTIVE

The purpose of this review is to explore and discuss existing approaches to technology-based driving interventions, driving assessments, and solutions in the literature.

METHODS

We searched the Web of Science and PubMed databases following a review protocol to collect relevant peer-reviewed journal articles. Inclusion criteria were (1) being published in the English language, (2) being published in a peer-reviewed journal, (3) testing the driving behavior of teens with technology-based intervention methods, and (4) being published between January 2000 and March 2018. We appraised the articles by reading their abstracts to select studies matching the inclusion criteria and reading the full text of articles for final refinement.

RESULTS

Initial keyword searches on technology-based solutions resulted in 828 publications that we refined further by title screening (n=131) and abstract evaluation against inclusion criteria (n=29). Finally, we selected 16 articles that met the inclusion criteria and examined them regarding the use of technology-based interventions, assessments, and solutions. Use of built-in tracking devices and installation of black box devices were widely used methods for capturing driving events. Smartphones were increasingly adapted for data collection, and use of gamification for intervention design was an emerging concept. Visual and audio feedback also were used for intervention.

CONCLUSIONS

Our findings suggest that social influence is effective in technology-based interventions; parental involvement for promoting safe driving behavior is highly effective. However, the use of smartphones and gamification needs more study regarding their implementation and sustainability. Further developments in technology for predicting teen behavior and programs for behavioral change are needed.
When More Than Exercise Is Needed to Increase Chances of Aging in Place: Qualitative Analysis of a Telehealth Physical Activity Program to Improve Mobility in Low-Income Older Adults (Preprint)
Authors: VanRavenstein Kathy , Davis Boyd H
Published: August 2018

BACKGROUND

A telehealth-delivered physical activity program was implemented within two low-income older adult housing properties utilizing the Otago exercise program, a physical therapy program endorsed by the Centers for Disease Control and Prevention to improve balance and strengthening in community dwelling older adults and by the National Council on Aging as the highest level of evidence for fall prevention programs. Participants were also given Fitbit activity monitors to help track their activity.

OBJECTIVE

The goal of this project was to increase older adults’ daily physical activity in hopes of decreasing chronic disease morbidity, disability, and falls, and decrease social isolation.

METHODS

The Otago exercise program was conducted via telehealth twice weekly for 12 weeks. Participants also wore Fitbit activity trackers to encourage physical activity outside of the group classes. Postintervention qualitative interviews were conducted, recorded, transcribed, and analyzed using discourse analysis.

RESULTS

Twenty-one older adult participants from two low-income properties in Charleston, SC, participated in the 12-week telehealth physical therapy program. Postintervention qualitative interviews revealed that the two sites were very different in their participation in the program and their main concerns surrounding aging in place. One site had a community-oriented outlook and enjoyed participating in physical activity together; whereas, the other site had very few participants and referenced depression and social isolation as main concerns.

CONCLUSIONS

A telehealth physical therapy-led intervention to increase physical activity in low-income older adults aging in place was successfully implemented and attended; however, it became clear in postintervention qualitative interviews that social isolation and depression were prevalent and mental health needs to be addressed along with physical health to encourage successful aging in place.

BACKGROUND

With the growing popularity of mobile health technology, app-based interventions delivered by smartphone have become an increasingly important strategy toward injury prevention.

OBJECTIVE

This study aimed to develop a framework supporting the design of an app-based intervention to prevent unintentional injury, targeted for caregivers of Chinese children aged 0 to 6 years.

METHODS

A theory-based mixed-method study, including focus groups and Web-based quantitative survey, was performed. Adult caregivers who care for children aged 0 to 6 years and own a smartphone were recruited into 2 sequential stages of research. First, focus groups were conducted among the caregivers at community health care centers and preschools from December 2015 to March 2016. Focus groups (8-10 participants per group) explored awareness, experiences, and opinions of caregivers toward using an app to prevent unintentional injury among children. Second, based on the focus groups findings, a Web-based quantitative survey was designed and distributed to caregivers in November 2016; it collected information on specific needs for the app-based intervention. Thematic analysis and quantitative descriptive analyses were performed.

RESULTS

In total, 12 focus groups were completed, involving 108 caregivers. Most participants expressed a strong desire to learn knowledge and skills about unintentional child injury prevention and held positive attitudes toward app-based interventions. Participants expressed multiple preferences concerning the app-based intervention, including their contents, functions, interactive styles, installation and registration logistics, and privacy protection and information security. Following the focus groups, 1505 caregivers completed a WeChat-based quantitative survey, which generated roughly similar results to those of focus groups and added numerical metrics concerning participants’ preferences on what to learn, when to learn it, and how to learn it. A detailed framework was established involving 5 components: (1) content design, (2) functional design, (3) interactive style, (4) installation and registration logistics, and (5) privacy protection and information security, and 15 specific requirements.

CONCLUSIONS

We developed a framework that can be used as a guide to design app-based interventions for parents and caregivers, specifically for unintentional injury prevention of children aged 0 to 6 years.

Published: August 2018

AbstractIn recent years, childhood obesity is considered one of the main health problems worldwide. The main objective of this study was to evaluate the psychological and familial factors associated with obesity in a group of children. Thirteen children with obesity, between 7 and 11 years old (eight boys and five girls), and 21 relatives (fathers/mothers/grandmothers), who were referred by the Pediatric Service of the Medical-Surgical Research Center, participated. The following variables were examined: eating habits, physical activity habits, body image, affective state, self-esteem, compensatory family affective relationships and potential attitudes that lead to psychological alterations in the family. The analysis was predominantly qualitative, through techniques such as the semi-structured interview with the child and the family, the psychographic analysis (free drawing and family drawing), as well as the Seven Figures of Collins. We conclude about the relevance of the influence in all the variables analyzed on childhood obesity. The need to implement psychological intervention programs addressing not only children, but also their families is imminent.Resumen En los últimos años la obesidad infantil es considerada uno de los principales problemas de salud a nivel mundial.

Authors: Murta Aurélio Lamare Soares , Pazzini Humberto Santiago , Motta Cristina Kurtz
Published: August 2018

A dependência mundial em relação à indústria do petróleo e as mudanças climáticas, que resultam no aquecimento global e aumento dos níveis dos oceanos, têm suscitado uma crescente necessidade de desenvolver novas formas de energia, renováveis e de menor impacto ambiental, como o biodiesel. Além da viabilidade econômica, o estudo abrange testes realizados por instituições de pesquisa e empresas que comprovam a viabilidade técnica do uso do biodiesel em veículos pesados. Deste modo, uma metodologia foi desenvolvida com o propósito de permitir que os testes sejam realizados com segurança e confiabilidade; conforme os procedimentos recomendados para percentuais maiores de mistura de diesel e biodiesel. O presente trabalho tem como objetivo realizar uma análise de viabilidade financeira, contemplando a autoprodução de biodiesel pela empresa Vale, para abastecimento da Estrada de Ferro Carajás – EFC, a partir análise de custos de produção do biodiesel de soja e palma. Como resultado final, verificou-se que o custo do biodiesel produzido nesta unidade foi significativamente superior ao preço final de venda do diesel obtido pela empresa junto às distribuidoras. Apesar de o investimento não oferecer o retorno mínimo esperado, existe a expectativa de que o aprimoramento dos processos produtivos do biodiesel, a fixação de limites de controle de emissões, assim como a alta no preço de combustíveis fosseis, tornem o preço desse biocombustível competitivo em relação diesel.

Published: August 2018

The air-flow fields of different spunbonding drawing conduits are modeled and
simulated numerically. Simulated results are compared with the measured
results and show good agreements with the latter. Results show that a larger
narrow length and a larger contracting length can produce a higher air
velocity, which is beneficial to the polymer drawing. This research is
valuable to the optimal design of the spunbonding drawing conduits.

Las malformaciones pulmonares congénitas son el resultado de diferentes tipos de trastornos en el desarrollo del árbol traqueobronquial, durante la vida embrionaria. A pesar de tener una baja incidencia, sus complicaciones pueden resultar determinantes para la sobrevida tanto a nivel prenatal como postnatal. Los tipos más frecuentes de malformaciones pulmonares son la malformación adenomatoidea quística y el secuestro broncopulmonar. El control durante el embarazo y la realización de ultrasonido permite el diagnóstico temprano, el estudio individualizado y la decisión terapéutica a seguir. Se debe siempre realizar el análisis histopatológico para determinar el riesgo de malignidad. Se presenta el caso de un paciente lactante de sexo masculino a quien se le detectó prenatalmente masa quística en hemitórax izquierdo; fue manejado quirúrgicamente a los 4 meses del nacimiento. En este tipo de casos, el conocimiento del tipo de malformación, su tamaño, compromiso respiratorio y posible manejo, resulta vital para el equipo interdisciplinario encargado del paciente, para asegurar un mejor pronóstico y calidad de vida

A pesar de haber sido sintetizadas desde 1887, las hidracinas e hidrazidas son un conjunto de compuestos del que sorprendentemente no se conocía su destino metabólico hasta años recientes. Actualmente, se sabe que las hidrazonas y sus complejos metálicos presentan innumerables aplicaciones farmacológicas. Los derivados de hidracinas, hidrazonas e hidrazidas se han utilizado como antibióticos, analgésicos, antiinflamatorios y antipiréticos. Asimismo, han tenido papeles importantes como antiplaquetarios, diuréticos, en la insuficiencia cardiaca y funciones antileucemia o en general como agentes antineoplásicos. En la industria funcionan como plastificantes, estabilizadores de polímeros, antioxidantes e iniciadores de la polimerización y las hidrazonas hidroxiladas se utilizan como herbicidas, insecticidas y estimulantes del crecimiento de plantas. Desde esta perspectiva, se puede observar que las hidrazonas tienen actividades farmacológicas promisorias. De ahí que se diseña este trabajo, para sintetizar, purificar y caracterizar compuestos tipo hidrazona con estructuras nuevas para, posteriormente, evaluar su actividad en líneas celulares específicas. El objetivo de este trabajo es la síntesis en condiciones Química Verde, así como la purificación y caracterización de la hidrazona que lleva el nombre de (E)–2–(2,2–difenilhidrazono)–1,2–difeniletan–1–ona. La espectroscopia de ultravioleta, infrarrojo, resonancia magnética nuclear y espectrometría de masas, procesos realizados a la hidrazona sintetizada, concuerdan con la estructura propuesta.

ResumenLas prácticas profesionales de la Universidad Piloto de Colombia se conciben como una estrategia pedagógica que aproxima a los estudiantes de Psicología a escenarios reales de intervención organizacional, articulando aspectos teóricos, metodológicos y conceptuales en el día a día de una empresa o institución. En ese sentido, la intervención organizacional adelantada por los practicantes debe sustentarse en un espacio de aprendizaje denominado Proyecto integrador el cual permite desarrollar competencias en las dimensiones del saber, el ser y el hacer. Este documento presenta un panorama de ejercicios académicos abordados por estudiantes de décimo nivel y que son más usuales en el área organizacional fortaleciendo la línea tradicional de la psicología organizacional.Por ende, este artículo se propone plantear una reflexión al respecto de los roles y las funciones que desempeñan los practicantes del área de Gestión Humana (Programa de Psicología, U.P.C.) dentro de las organizaciones en las cuales adelantan su labor. De una manera descriptiva se identifican las áreas tradicionales de trabajo en las que el estudiante de último semestre se desenvuelve durante su periodo de práctica, no obstante, al mismo tiempo se señalan otras posibilidades de intervención que pueden realizar en las organizaciones.Palabras clave: Psicología organizacional, práctica profesional, gestión humana, intervención, espacios de aprendizaje.Abstract The professional practices of the Universidad Piloto de Colombia are conceived as a pedagogical strategy that brings students of Psychology closer to real scenarios of organizational intervention, articulating theoretical, methodological and conceptual aspects in the daily life of a company or institution. In this sense, the organizational intervention advanced by the practitioners must be based on a learning space called Project Integrator which allows developing competencies in the dimensions of knowledge, being and doing. This paper presents a panorama of academic exercises addressed by tenth-level students which are more usual in the organizational area by strengthening the traditional lines of organizational psychology.Therefore, this article proposes to reflect on the roles and functions of practitioners in the area of Human Management (Psychology Program, U.P.C.) within the organizations in which they advance their work. In a descriptive way, the traditional areas of work are identified in which the student of last semester develops during his period of practice, however, at the same time other possibilities of intervention that can be realized in the organizations are indicated.Keywords: professional practice, intervention, human management, learning, organizational
The largest Baltic population of sea trout (Salmo trutta L.): its decline, restoration attempts, and current status
Authors: Dębowski Piotr
Published: August 2018

The sea trout, Salmo trutta L. population in the Vistula River was the largest in the Baltic Sea. Its primary spawning grounds were located in the Carpathian tributaries in the upper river basin. The fish ascended to spawn in two runs: in winter when the fish were immature and spent nearly a whole year in the river, and in summer when mature fish ascended the river and spawned within a few months. This work presents the fisheries and stocking history and scientific studies of this population from the late nineteenth century. The consequences of the most important changes in the sea trout habitat are tracked from construction in the upper river basin in the 1940s and the damming of the river in its middle reaches in Włocławek in 1969. Despite intense stocking that has been conducted for over one hundred years, catches have declined from over 100 tons to nearly zero in recent years. The current state of the population and the possibilities of restoring it are discussed in light of genetic studies.
