Published: October 2018

RESUMO A gestão dos recursos hídricos e energéticos é o principal desafio que a sociedade contemporânea enfrenta atualmente. Água e energia são fatores fundamentais para o desenvolvimento socioeconômico das comunidades, principalmente aquelas situadas em locais remotos, e, nesse cenário, a falta de energia é o aspecto mais preocupante. Os sistemas de bombeamento fotovoltaico apresentam vantagens para a inserção em comunidades isoladas, como fácil instalação e pouca manutenção durante o ciclo de vida, porém o dimensionamento inadequado pode gerar gastos desnecessários ou comprometer o abastecimento de água. Simular o desempenho favorece a concepção de sistemas e permite alcançar a otimização técnica e econômica em projetos da referida tecnologia. O estudo propõe um modelo matemático de simulação e a utilização do generalized reduced gradient (GRG) e de dados regionais de radiação solar, de consumo de água, de produtividade de poços e de capacidade do sistema de bombeamento para obter a referida otimização. A validação do respectivo modelo foi realizada em um sistema piloto, localizado em uma comunidade rural no município de Orleans, no Estado de Santa Catarina. A localidade apresenta uma das menores médias de radiação anual no país, aproximadamente 4,5 kWh.m-2/dia. A simulação efetuada nas condições naturais do sistema piloto mostrou resultados bem próximos do comportamento monitorado, evidenciando, assim, a eficiência do modelo. O uso da ferramenta auxilia no processo de tomada de decisão quanto à concepção de projetos, além de beneficiar as comunidades com acesso à água e à energia, trazendo benefícios em todas as esferas: social, ambiental e econômica.

Published: October 2018

ABSTRACT This study investigates the potential use of amino-functionalized silica gel as an adsorbent for the recovering of congo red dye from aqueous solution. The effects of pH, contact time, and temperature were determined and evaluated. Equilibrium isotherms were also studied. The adsorption kinetics was modeled by pseudo-first order and pseudo-second order. Furthermore, desorption of congo red was preliminarily studied. The pH range from 4.5 to 7.0 was favorable for the adsorption of congo red onto amine modified silica at 25ºC. Higher adsorption capacity was obtained at 50ºC. Langmuir and Freundlich models were fitted to the adsorption equilibrium data. The best fittings were obtained with the pseudo-second order and Langmuir model for kinetics and equilibrium, respectively. Desorption studies suggest that ion exchange might be the major mode of adsorption. KOH solution was the best desorbing agent for recovering the adsorbed dye.

Published: October 2018

RESUMO No Brasil e no mundo, o setor dos transportes de passageiros e cargas tem contribuído decisivamente para o aumento das emissões de poluentes atmosféricos, com os consequentes problemas para o meio ambiente e para a saúde humana. Assim, muitos estudos têm recorrido a metodologias e/ou ferramentas específicas para modelar e simular poluentes atmosféricos. A frota de veículos no Ceará teve um crescimento de 169% nos últimos 10 anos, mas ainda se desconhece o volume de poluentes emitidos pela frota circulante da Região Metropolitana de Fortaleza (RMF). Nesse contexto, foram estimadas as emissões veiculares de escapamento para a RMF no ano de 2010. A quantificação das emissões de monóxido de carbono (CO), hidrocarbonetos não metano (NMHC), óxidos de nitrogênio (NOx), material particulado (MP) e aldeídos (RCHO) foi realizada através da metodologia bottom-up. De modo geral, as motocicletas apresentaram emissões significativas de poluentes, sobretudo de CO, NOx e MP, devido à grande quantidade de veículos na região. Os veículos ciclo Otto representam mais de 90% das emissões totais de CO, NMHC e RCHO, enquanto os veículos ciclo Diesel emitem mais de 85% das emissões totais de NOx e MP.

Published: October 2018

RESUMO A geração de resíduos finos provenientes do processo de beneficiamento de rochas ornamentais cresce na mesma proporção da produção de chapas para a construção civil. A adoção de medidas preventivas, remediadoras e punitivas está atrelada ao conhecimento do verdadeiro potencial que esses materiais têm para causar impactos negativos ao ambiente. O objetivo deste trabalho foi simular, em laboratório, possíveis alterações na qualidade da água de recarga de aquíferos provocadas pela disposição inadequada desses resíduos. Foram realizados testes de percolação de água em colunas de solo recoberto por resíduos com diferentes taxas de umidade: resíduos sem tratamento, saídos diretamente do tear (TE); resíduos que passaram por filtro prensa (FP) para redução de umidade e resíduos secos em leito de secagem (LS). A água de percolação foi analisada para avaliar alterações em comparação com um branco ou testemunha. Não foram detectadas alterações significativas no pH da água percolada em nenhum dos casos estudados. Porém, no tratamento TE houve alterações em vários parâmetros de qualidade. A água percolada através do resíduo FP se assemelhou àquela do TE em alguns parâmetros e à do LS em outros. Conclui-se que os resíduos saídos diretamente da boca do tear possuem alto potencial de degradação da qualidade da água, mas a redução de umidade é eficaz para reduzir os riscos ambientais. O uso de LS pode ser um método tão eficaz quanto o FP, se conduzido de forma adequada e respeitando as normas legais.

Published: October 2018

ABSTRACT Objective: To investigate the meanings given by women caregivers to their care practices and to analyze the relationship between such practices and their work history. Method: This was a phenomenological qualitative cohort study conducted in Seville, Spain, with family caregivers. Data were collected using semi-structured interviews and submitted to content analysis, using Atlas-ti GmbH software version 5.0®. The following categories emerged: caregiving history and work history, and the meaning of care in their lives. Results: Twenty caregivers participated in the study. Women caregivers told stories of wide-ranging care, including several individuals in their family at different moments. They performed different forms of care, encompassing physical and social dimensions. Their discourse expressed the contradiction between their caregiving role and entering and/or maintaining their place in the labor market. Conclusion: The women expressed a concept of comprehensive care that includes responsibility, availability, and companionship, as well as emotional states, which greatly impact health. They tailored their participation in the labor market according to their family’s care needs. Thus, the gender perspective must be incorporated by health care providers who work with the health of caregivers.

Reinforced concrete ribbed slabs with wide-beam
Authors: SACRAMENTO P. V. P. , PICANÇO M. S. , OLIVEIRA D. R. C.
Published: October 2018

Abstract Ribbed slabs have been widely used in buildings due to their many advantages, especially the decrease of concrete below the neutral line. This paper presents an experimental and computational study on ribbed slabs with wide-beam, two one-way slabs and two two-way slabs, with variable depths were tested to evaluate their resistance to punching and shear strength of slabs. Experimental and computational results showed that the wide-beam ribs connection is a critical point in the design of the slabs due to the difference in stiffness in the transition zone. Best results for the ultimate load estimates for ribs were provided by EC 2 (2004), while estimates of ACI 318 (2008) and NBR 6118 (2014) were respectively conservative and unsafe. Test results on slabs also revealed that the Brazilian alternative to analysis ribbed slabs as solid ones failed to give satisfactory results.

Published: October 2018

Abstract This paper carries out a design analysis of reinforced concrete beams with steel fibers following the fib Model Code 2010 (MC 2010) procedures. The values obtained from the design calculations are compared with the experimental results of reinforced concrete beams with 20kg/m3 and 60 kg/m3 of steel fibers submitted to four-point bending tests. In the first part, the procedures for the classification and characterization of the material are explained. The experimental results of three-point bending tests performed on notched steel fiber reinforced concrete (FRC) beams following EN 14651 procedures are described. Moreover, the characterization of the FRC beams according to MC 2010, are carried out. In the second part, the flexural design of reinforced concrete beams with steel fibers, according to MC 2010, is carried out. A sectional analysis is performed in order to obtain the moment-curvature and the force-vertical displacement curves. The theoretical values are compared with the experimental results. Besides, a linear statistic analysis by means of the Rule of Mixture is carried out in order to analyze the variation of the flexural capacity of the reinforced beams with different amounts of steel fibers. The results demonstrated that the design rules described in the MC 2010 are on the safe side. The flexural resistance of concretes with different amounts of fiber incorporation can be determined by the Rule of Mixture, which has shown a high correlation factor (R2) with the experimental values.
Evaluation of the SR Portland cement against sodium and magnesium sulfate attack: a physical and comparative analysis of mortars
Authors: SOUZA D. J. de , MEDEIROS M. H. F. , HOPPE FILHO J.
Published: October 2018

Abstract Sulfate attack is a term used to describe a series of chemical reactions between sulfate ions and hydrated compounds of the hardened cement paste. Thus, the chemical composition of the binders used is important for the durability of the structure against this aggressive agent. The objective of the present research is to evaluate the influence of sodium and magnesium sulfates on physical properties (linear expansion, flexure tensile strength, and compressive strength) of mortars composed by SR cement (CP V - ARI RS), as commercially sold in Brazil. The results indicate that SR cement complies the requirements established by Brazilian standards, as to chemical composition and resistance to sodium sulfate. However, for magnesium sulfate, SR cement was harmful to mortars mainly in mechanical.

Published: October 2018

It is presented case report of multiple endocrine neoplasia type 1 (Wermer’s syndrome). This syndrome is characterized by a large variability of clinical manifestations. In our case, there was a combination of primary hyperparathyroidism and simultaneous neuroendocrine tumors of the pancreatic tail and portal area. We have not found similar cases with portal gastrinoma in the available literature. Simultaneous subtotal parathyroidectomy, distal pancreatectomy with excision of portal insulinoma and partially extrahepatic bile ducts followed by hepaticojejunostomy were performed. This observation demonstrates the modern diagnostic and surgical methods in patients with MEN-1 syndrome and neuroendocrine tumors.

Psychological Characteristics of Self-Image and Self-Assessment in Adolescents with Impaired Renal Functioning of Different Severity
Authors: Vachkov I. , Zaruba D.A. , Kurtanova Y.E.
Published: October 2018

The article presents the study results of the features of self-assessment and self-image of three groups of adolescents: with a mild degree of renal failure, in the terminal stage (waiting for a kidney transplant) and healthy, who formed the control group. The main results of the comparative analysis of these groups were the identification of similarities or minor differences in the parameters of self-assessment and self-image among healthy adolescents and adolescents with mild renal dysfunction, as well as the identification of statistically significant differences between the first two groups and the group of adolescents in the terminal stage of kidney disease on a number of scales and indicators. These differences are found, first of all, in higher egocentricity, uncritical, in poor, superficial and poorly differentiated representation of themselves in adolescents of the last group. Their self- assessment is low, while the level of claims is high and particularly sharply overstated on the Health scale; there is a significant gap between the assessment of the available condition and the desired one.
Gelotophobia, Gelotophiles, and Katagelasticists in Patients with Depression
Authors: Lubavskaya A.A. , Oleichik I. , Ivanova E.M.
Published: October 2018

The article presents a study of gelotophobia (the fear of being laughed at) for depression. 32 patients with depressive syndrome and 33 mentally healthy people were examined with a complex of methods: clinical interview, the Liebowitz Social Anxiety Scale, the Fear of Negative Evaluation Scale, gelotophobia, gelotophilia and katagelasticism questionnaire the PhoPhiKat<30>, the Guilt and Shame Proneness scale (GASP), the Beck Depression Inventory, and the Buss-Perry Aggression Questionnaire. The results showed higher gelotophobia (the fear of being laughed at) in patients with depressive syndrome in comparison with the control group, and, on the other hand, lower gelotophilia (the joy of being a target of laughter) and katagelasticism (the joy of laughing at others). No differences on gelotophobia were found in the subgroups of patients with depression within schizophrenia and affective disorders. Gelotophobia under depression was closely connected with social anxiety and the fear of negative evaluation, but was not associated with aggression. Although depression includes experiencing both guilt and shame, gelotophobia characterized only those patients who tended to experience shame. The results of the study allow to reveal specifics of the fear of being laughed at under depression, which may be used in clinical diagnostics and psycho-rehabilitation of these patients.
The Effectiveness of Life Skills Training on Life Satisfaction in Patients with Spinal Cord Injury
Authors: Ramezani F. , Mazraeh S.
Published: October 2018

Spinal cord injury (SCI) is one of the most debilitating diseases that affects all aspects of person’s life. Researches have indicated that life satisfaction in these patients is lower than that of others. The aim of this study was to investigate the effect of life skills training on life satisfaction in patient with spinal cord injury. This study, having a quasi-experimental design, was performed with pre-test, post-test, and control group. The statistical population of this study consisted of patients with spinal cord injury (only men) that is covered by the home health care team of the Kahrizak Charity Foundation of Tehran. To do research, 30 patients of the center were selected by availability sampling and were randomly divided into experimental and control groups. In the experimental group, 10 sections of life skills training were performed, while no intervention was used for the control group. The research tool used in this study was a Self-Life Satisfaction Questionnaire and a univariate analysis of covariance was used to test results. Findings from the analysis of covariance showed that there was a significant difference between experimental and control groups (p< 0,05). This indicated that life skills training improved the life satisfaction in patients with spinal cord injury.
First-Person Video Modeling as a Way of Teaching Imitation of Children with Autism
Authors: Novgorodtseva A.P. , Yakovleva N.V.
Published: October 2018

The article discusses the problem of the basic factors of ASD: the deficit in the Theory of Mind (ToM) as the ability to represent Self-Other relationship, or violation of the ability to simulate, as the ability to transfer the perspective of Other’s action into the prospect of their own actions. It is hypothesized that the first-person video surveillance technique (with the instructor’s and the student's hands visible) will be more effective in teaching imitation of children with ASD than the third-person video surveillance method (where the instructor and the student are seen). The study involved 28 children attending classes with psychologists and speech pathologists (ages: 4, 10 up to 7, 4 years; 24 children were diagnosed with ASD, 4 – atypical autism). At the first stage, the level of motor simulation skills (ABLLS-R test) was evaluated-3 times with an interval of 1 week. On the second stage, three groups (9 people) were equalized at the level of development of imitation. One group was trained "third-person", the second – "first-person", the third – control was trained according to the standard program. All studied the same time. For each subject conducted
4 classes (2 times a week). At the third stage, the level of motor skills measured 3 times with an interval of 1 week. The processing took into account the parameters of the mean, median, mode and standard deviation. The results of the study showed significant effectiveness of third-person training. The shift of the average value in "third-person training" and "first-person training" was 3 and 8 units respectively.
Proactive Coping Inventory: Adaptation to a Non-Clinical Sample and the Predictive Capability
Authors: Belinskaya E.P. , Veсherin A.V. , Agadullina E.R.
Published: October 2018

The article presents the results of the Russian-language adaptation of the proactive copying questionnaire. The study involved 405 Russian-speaking respondents (age from 18 to 63 years, M = 20,5 , SD = 6,97). Based on the analysis of scales and confirmatory factor analysis, the full version of the questionnaire on the Russian-language sample showed unsatisfactory psychometric indicators. A short version of the questionnaire is proposed, which corresponds well to empirical data. Based on the regression analysis, proactive coping strategies were identified. These strategies are predictors of high life satisfaction. The greatest contribution to the level of satisfaction with life is the search for emotional support and proactive copying. On the basis of structural modeling, the relationships of coping strategies, positive and negative emotions and life satisfaction were studied. The results show that the predictors of life satisfaction are positive emotions and a person's confidence that he will successfully solve a difficult life situation.
A Vector Potential Function-Based Collision Avoidance Control for Differential-Steered Robots
Authors: Pamosoaji Anugrah K
Published: October 2018

A collision avoidance control that tracks a vector potential field-based velocity plan of a differential-steered robot is designed. Vector potential function (VPF) is a type of potential function used for motion planning. The plan resulted by the VPF is the desired velocity vector of the robot on all points in collision-free space. The problem to address in this paper is velocity tracking control in the environment of a circular obstacle. A controller is designed to track the VPF-based velocity plan. A concept of collision cone will be used to evaluate the ability of the controller to avoid collision between the robot and the obstacle. The stability of the controller is verified by using the Lyapunov stability analysis. Simulations of the controllerâ€™s performance are presented.

A 300A Dynamic Electronic Load Based On Modified Buck+boost Interleaved Converter
Authors: De Seixas Falcondes J. M. , De Seixas Claudiner M. , Canesin Carlos A.
Published: October 2018

This paper presents a novel DC dynamic electronic load applied at load regulation tests of switching-mode power supplies, operating at highcurrent levels. The proposed device is based on the use of a modified Buck+Boost interleaved converter, without the use of the boost diodes, and the output filters (capacitors). Therefore, the electronic load circuitry is very simple, effective and capable to provide high pulsedcurrent levels, featuring faster rise/fall times for transient testing on high speed DC to DC converters and DC power supplies. A prototype was implemented, in order to validate the proposed structure, operating at 10V-20V DC input voltage range, 190A-290A amplitude range of the input pulsed-current (nominal value is equal to 240A±20%), with adjustable pulse-width between 4ms (adjustable time-period of 200ms) until 6ms (adjustable time-period of 350ms). The main experimental results, obtained from the implemented prototype, are presented in order to demonstrate the feasibility of the proposed dynamic electronic load, which is capable of performing experimental tests of transient load regulation for switching-mode power supplies.

Modelo Resistivo Para Lâmpadas Fluorescentes Alimentadas Por Inversor Srpl, Com Controle De Luminosidade Por Variação De Freqüência De Operação
Authors: Wakabayashi Fabio T. , Dantas Fausto D. , Pinto João Onofre P. , Canesin Carlos A.
Published: October 2018

Este artigo apresenta uma nova metodologia para a determinação de modelos baseados em resistências equivalentes para lâmpadas fluorescentes de cátodo quente, alimentadas com o clássico inversor Half-Bridge com filtro Série-Ressonante com Carga em Paralelo (SRPL, do inglês, Series-Resonant Parallel-Loaded). A técnica de controle de luminosidade considerada nas análises é baseada na variação da freqüência de operação do inversor. A principal contribuição da metodologia proposta é a inclusão dos filamentos dos eletrodos no modelo, considerando-se os efeitos da variação da freqüência de operação sobre o conjunto lâmpada + filtro SRPL. Informa-se que o modelo proposto não é válido para caracterizar a lâmpada de forma isolada, mas sim o conjunto desta com o filtro SRPL. Resultados experimentais mostrados neste artigo, obtidos com uma lâmpada fluorescente F32T8, indicam que a precisão do modelo é bastante satisfatória.

The Keyboard Instruments

Published: October 2018

When I was growing up, it seemed like posture was a big deal—to my parents, other (older) relatives, teachers, and other authority figures. Hardly a day passed (as I recall) without an adult telling me to stand up taller or sit up straighter. ... On the other hand, I have suggested
to a number of music students who have come in to see me about a performance-related musculoskeletal disorder (PRMD) that they should talk with their teacher and a physical therapist about their posture and the effect it may be having on their body and their performance. So how can we best
understand the relationships among posture, performance, and injury in the performing arts? The article by Ramella et al. in this issue of MPPA gives us some new information about the potential importance of posture for instrumental musicians. In order to provide some context for this article,
I will try to give a brief overview of what we know about posture and the health of performing artists.
Intensive Short-Term Dynamic Psychotherapy for Severe Music Performance Anxiety: Assessment, Process, and Outcome of Psychotherapy with a Professional Orchestral Musician
Authors: Kenny Dianna T , Arthey Stephen , Abbass Allan
Published: October 2018

This paper reports on the process and outcome of therapy using intensive short-term dynamic psychotherapy (ISTDP) with a professional musician who had suffered severe music performance anxiety over the course of his entire 30-year career. In this paper, we describe the nature of the
therapy, the case history of the musician, the first assessment and trial therapy session, and the course and successful outcome of therapy. The patient underwent 10 sessions of ISTDP over a period of 4 months. This paper reports on the first 6 sessions, which were most relevant to the understanding
and treatment of the patient’s severe music performance anxiety. This case study is the first reported application of ISTDP to a professional musician. We believe that this case study provides initial support that moderate to severe performance anxiety, in at least some cases, has its
origins in unresolved complex emotions and defences arising from ruptures to early attachment relationships.

Authors: Spahn Claudia , Nusseck Manfred , Zander Mark
Published: October 2018

OBJECTIVES: The aim of this investigation was to analyze longitudinal data concerning physical and psychological health, playing-related problems, and preventive behavior among music students across their complete 4- to 5-year study period. METHODS: In a longitudinal, observational
study, we followed students during their university training and measured their psychological and physical health status and preventive behavior using standardized questionnaires at four different times. RESULTS: The data were in accordance with previous findings. They demonstrated three groups
of health characteristics observed in beginners of music study: healthy students (cluster 1), students with preclinical symptoms (cluster 2), and students who are clinically symptomatic (cluster 3). In total, 64% of all students remained in the same cluster group during their whole university
training. About 10% of the students showed considerable health problems and belonged to the third cluster group. CONCLUSION: The three clusters of health characteristics found in this longitudinal study with music students necessitate that prevention programs for musicians must be adapted
to the target audience.
Postural Disorders in Conservatory Students: The Diesis Project
Authors: Ramella M , Fronte F , Converti RM
Published: October 2018

Prolonged and incorrect postures are one of the main risk factors for the development of musculoskeletal pathologies. The aims of this study were to study the prevalence of incorrect postures among conservatory students; to identify if the use of an asymmetric instrument represents
a risk factor for developing postural disorders; and to investigate whether a correlation exists between years of study, physical activity, and prevalence of postural disorders. METHODS: The subjects were recruited among students of the Giuseppe Verdi Conservatory of Milano. All musical instruments
were investigated and classified as asymmetric and symmetrical. The observed student posture was classified without instrument as “correct posture” or “postural disorder” and with an with instrument as “optimal posture” or “non-optimal posture.”
While playing, the postural disorder was classified as “unchanged” or “increased.” The data were analyzed with chi-square and linear regression methods. RESULTS: Of the 148 conservatory students entered into the study, 66.2% had a postural disorder; 73.4% had a non-optimal
posture, and playing an asymmetric instrument was the only variable associated (p=0.01). While playing, the postural disorder was increased in 59.2%; playing an asymmetric instrument (p=0.01) and years of practice (p=0.007) were the significantly associated variables. CONCLUSIONS: To play
an asymmetric instrument exposes musicians to an increased risk of non-optimal postures and to a worsened postural disorder when present. Considering that the years of practice have an additional negative impact on postural disorders, further studies are needed to clarify the role of non-optimal
postures in the development of musculoskeletal complaints among students and professional musicians.

Now that the field of performing arts medicine has been in existence for over three decades, we are approaching a key point: we should start to see more articles that bring together the data that have been collected from several studies in order to draw more robust conclusions. Review
articles and their more structured relative, the meta-analysis, can help to improve our understanding of a particular topic, comparing and synthesizing the results of previous research that has been done on that subject area. One way this could be done would be to review the research that
has been carried out on the performance-related problems associated with playing a particular instrument or group of instruments. ... In this editorial, I will do a very selective review of the playing-related musculoskeletal disorders (PRMDs) associated with one instrument group (the keyboard
instruments), focusing on the most played instrument in that group (the piano).
Comparing Violinists’ Body Movements While Standing, Sitting, and in Sitting Orientations to the Right or Left of a Music Stand

Published: October 2018

OBJECTIVES: For violinists, it is common practice to play while standing or sitting. When playing in an orchestra, generally two persons share one music stand, with one sitting to the right and the other to the left of the stand. The present study investigated specific movement patterns
while playing in these different positions. METHODS: Using a posturographic device and 3D motion capture, the body weight distributions and specific body movements of 19 violinists were analyzed. RESULTS: Results showed unbalanced weight distributions while sitting in front of or oriented
to the right of the music stand compared to the almost even distributions while standing or oriented to the left of the stand. Analyses of movement patterns showed significant differences between standing and sitting, mainly in the upper body parts with less movability while sitting. While
sitting in front of or oriented to the right of the music stand, the right bowing arm showed more restricted movements compared to other positions. CONCLUSION: The playing positions are discussed with regard to possible physiological stress and health risks. The study emphasizes the importance
of different playing positions and offers starting points for discussion of postural influences and sensible handling of the instrument in performance and practice for violinists.
Physical Activity Helps to Control Music Performance Anxiety
Authors: Rocha Sérgio F , Marocolo Moacir , Corrêa Elisangela NV , Morato Gledys SG , da Mota Gustavo R
Published: October 2018

We evaluated if regular physical activity could influence musical performance anxiety (MPA) in college music students. Levels of MPA, as measured with the Kenny MPA Inventory, and a survey about the physical activity habits were obtained from 87 students of music. The results showed
that physically active musicians had lower MPA scores (p<0.05) than non-active ones, independent of gender. We conclude that there is an association between physical activity and minor MPA, and studies with a longitudinal design should be done to explore this important issue.
Mental Problems Among First-Year Conservatory Students Compared with Medical Students
Authors: van Fenema EM , van Geel CCJ
Published: October 2018

Musical education and the musical profession can be stressful, which may make musicians vulnerable for stress-related disorders. To determine if music students are particularly at risk for mental problems, we used the Standardised Assessment of Personality–Abbreviated Scale [SAPAS]
and the Symptom Questionnaire [SQ48] to compare symptoms in first-year conservatory students (n=33) and first-year medical students (n=43). On the SAPAS, we found that medical students have significantly more difficulty making and keeping friends (p=0.015). Also, we observed a trend that conservatory
students lose their temper more easily (p=0.040). Both student groups showed high scores for the personality trait “perfectionism.” On the SQ48, we observed a trend that both conservatory and medical students experience more psychological problems than the general population, but
there were no significant differences between conservatory students and medical students in the total scores of both questionnaires.

Three-Dimensional Analysis of the Cranio-Cervico-Mandibular Complex During Piano Performance
Authors: Clemente M , Lourenço S , Coimbra D , Silva A , Gabriel J , Pinho JC
Published: October 2018

Piano players, as well as other musicians, spend a long time training to achieve the best results, sometimes adopting unnatural body positions that may cause musculoskeletal pain. This paper presents the preliminary results of a study targeting the analysis of the head and cervical
postures of 17 piano players during musical performance. It was found, as a common feature, that the players tilt the head to the right and forward towards the score and keyboard. Players who know the score by heart tend to move their heads more compared to the ones who have to keep their
eyes on the score.
Achilles and Patellar Tendon Morphology in Dancers with and without Tendon Pain

Published: October 2018

OBJECTIVES: To examine Achilles and patellar tendon morphology in dancers with and without tendon pain. METHODS: Fifty-three dancers with and without Achilles and/or patellar tendon pain participated. Eleven age-matched non-dancers served as controls. Longitudinal ultrasound images
of the middle and distal Achilles and proximal and distal patellar tendons were acquired. To assess macromorphology, the thickness of the middle and distal Achilles and proximal and distal patellar tendons were measured. Micromorphology was analyzed by selecting 2 x 2-mm2 regions of interest
in the tendons; spectral analysis using the fast Fourier transform was run for several kernels (2 x 2-mm2 subimages) within each image, and the peak spatial frequency (PSF) was extracted. A one-way ANOVA compared asymptomatic, symptomatic, and control tendon thickness and PSF. RESULTS: Macromorphology:
There was no significant difference between asymptomatic and symptomatic dancers in middle or distal Achilles tendon thickness and distal patellar tendon thickness. Proximal patellar tendons in control subjects were thinner than those in asymptomatic (p=0.036) and symptomatic (p=0.003) dancers.
Micromorphology: There was no significant difference in PSF between asymptomatic and symptomatic dancers and controls in the Achilles or patellar tendon. CONCLUSION: Increased proximal patellar tendon thickness without changes in tendon micromorphology suggests that tendon adaptations are
more likely activity-related and less likely influenced by degeneration.

Once again, multiple articles on individual topics grace this column: three publications on musical talent are followed by four on sound exposure and hearing loss in music teachers and professional musicians. Although there is no hard evidence to support the theory, the frequency of
multiple articles appearing over a short time period may reflect the level of current interest and perceived importance of these topics in the world of research. Installment no. 65
The Relationship between Preservice Teachers’ Attitudes towards Statistics and Their Research Anxiety
Authors: TAŞGIN Adnan , KAYA Yasemin
Published: October 2018

The aim of this study was to investigate the
relationship between preservice teachers’ attitudes towards statistics and
their research anxiety. The population of the study consisted of the students
of a public university in Turkey who were studying at the Guidance and
Psychological Counseling, and the Preschool Education programs. From this
population, 257 participants were sampled for this research based on scale
sampling method. In order to determine the attitudes and the anxiety of the
participants towards statistics and research, two separate scales were to the
participants. The scale of attitudes towards statistics consisted of 33 items,
which assessed five subscales. The scale of research anxiety consisted of 12
items measuring a single factor. The data were analyzed through independent
samples t-test and correlation analyses. The study results suggested that the
female preservice teachers had more positive attitudes towards statistics than
the male preservice teachers. On the other hand, the male preservice teachers’
research anxiety levels were lower than the female preservice teachers.
Moreover, the attitudes and the anxiety levels showed significant differences
based on the departments of the preservice teachers in favor of the Guidance and
Psychological Counseling department. Finally, a positive correlation found
between the research anxiety and the attitudes towards statistics levels of the
participants.

Colorectal Cancer (CRC) is one of the most common cancers with a high rate of morbidity and mortality
worldwide. It has been demonstrated that epigenetic alterations which may cause changes in the expression of
microRNA, DNA methylation and histone acetylation that results in inheritable modifications in gene expression
in colorectal epithelial cells, plays a crucial role in the development of CRC. Recently, targeting epigenetic modification
has emerged as a potentially important treatment approach in CRC. The US Food and Drug Association
has approved the use of some epigenetic drugs that may be able to inhibit or reverse these alterations and also
enhance sensitivity to chemotherapeutic agents and radiotherapy in CRC. In this review we have summarized the
recent pre-clinical and clinical trial studies investigating the therapeutic value of using epigenetic drugs as novel
therapeutic approach in CRC treatment.

Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease described as a lack of destruction of bacteria and fungi phagocytes by neutrophils and macrophages, it is related to an abnormality of NADPH oxidase, a free radical producer of oxygen. The most common aspect of CGD at the age of one year, is an infection of the skin or bone by two bacteria called staphylococcus aureus and serratia marcescens. In this article, the authors report a case of CGD revealed by multiple cystic and pseudo-tumoral liver lesions discovered during prolonged fever.
FOREIGN DIRECT INVESTMENT IMPACT ON MARKET CONCENTRATION IN THE MANUFACTURING SECTOR OF BOSNIA AND HERZEGOVINA
Authors: Kastratović Radovan
Published: October 2018

There is no consensus regarding the effect of foreign direct investment on market concentration in the literature of foreign direct investment and the theory of industrial organization. The aim of the research is to empirically investigate this impact in the context of the manufacturing sector of Bosnia and Herzegovina. To achieve this aim we estimate the econometric model by applying ordinary least square method. The sample of 21 industries comprising manufacturing sector of Bosnia and Herzegovina was used for model estimation. Cross-sectional sample data was obtained from the Central Bank of Bosnia and Herzegovina and the financial reports of 4924 companies registered in the aforementioned industries for the year 2016. The results suggest that the impact of foreign direct investment on market concentration can best be described with a convex function.
