Published: October 2019

Background: Renal cell carcinoma accounts for 85% of all solid tumors of the kidney. For many years, radical nephrectomy was the stan­dard treatment for RCC. Partial nephrectomy has gradual­ly replaced radical nephrectomy over the past decade, es­pecially for T1 stage renal cell carcinoma. However, the benefit of partial nephrectomy on oncolog­ic outcomes is not well known.Objective: to investigate the clinical outcome of partial nephrectomy on T1 renal cell carcinoma. Methods: This prospective observational study was conducted in a single unit of urology department of Dhaka Medical College Hospital, Bangladesh from the period September 2014 to September 2017. Fourteen patients underwent partial nephrectomy during this period with renal mass based on eligibility criteria. Two follow up was done at three months and six months. Result: Mean age of the patients undergoing surgery was 52.0± 3.8 (46.0 to 57.0 years) years. For the majority of the patients, tumour size was in a range of 3-7 cm. Average operative time was 90 minutes and mean ischaemic time was 16.5 ± 4.6 minutes (14.5 to 21.0 minutes). Histopathological reports correlated with clinical diagnosis and showed adequate surgical clear margin in every case.  There was no recurrence of tumour noticed during the two follow up periods. The different investigation did not reveal the impaired renal functional test during the follow-up period. Conclusion: The clinical outcome of partial nephrectomy was found better in this study. Partial nephrectomy has the potential to replace radical nephrectomy for managing T1 tumours. However, there are some controversies regarding the post-operative oncological outcome. More studies are recommended to investigate the effect of partial nephrectomy for T1 tumours.

Experimental and computational electrochemistry of quinazolinespirohexadienone molecular switches – differential electrochromic vs photochromic behavior
Authors: Webb Eric W , Moerdyk Jonathan P , Sluiter Kyndra B , Pollock Benjamin J , Speelman Amy L , Lynch Eugene J , Polik William F , Gillmore Jason G
Published: October 2019

Our undergraduate research group has long focused on the preparation and investigation of electron-deficient analogs of the perimidinespirohexadienone (PSHD) family of photochromic molecular switches for potential application as "photochromic photooxidants" for gating sensitivity to photoinduced charge transfer. We previously reported the photochemistry of two closely related and more reducible quinazolinespirohexadienones (QSHDs), wherein the naphthalene of the PSHD is replaced with a quinoline. In the present work, we report our investigation of the electrochemistry of these asymmetric QSHDs. In addition to the short wavelength and photochromic long-wavelength isomers, we have found that a second, distinct long-wavelength isomer is produced electrochemically. This different long-wavelength isomer arises from a difference in the regiochemistry of spirocyclic ring-opening. The structures of both long-wavelength isomers were ascertained by cyclic voltammetry and 1H NMR analyses, in concert with computational modeling. These results are compared to those for the symmetric parent PSHD, which due to symmetry possesses only a single possible regioisomer upon either electrochemical or photochemical ring-opening. Density functional theory calculations of bond lengths, bond orders, and molecular orbitals allow the rationalization of this differential photochromic vs electrochromic behavior of the QSHDs.

Published: October 2019

The source G25.65+1.05 (RAFGL7009S, IRAS 18316-0602) is the least studied of the three regions of massive star formation known to show exceptionally powerful H2O maser bursts. We report spectral line observations of the H2O maser at 22 GHz, the methanol maser transitions at 6.7, 12.2, and 44 GHz, and the continuum in these same frequency bands with The Karl G. Jansky Very Large Array at the post-burst epoch of 2017. For the first time, maps of 22 GHz H2O and 44 GHz CH3OH maser spots are obtained and the absolute position of the 22 GHz H2O bursting feature is determined with milliarcsecond precision. We detected four continuum components, three of which are closely spaced in a linear orientation, suggesting a physical link between them.
Unbiased Distribution of Binary Parameters from LAMOST and Kepler Observations
Authors: Zhang 张 Jia 嘉 , Qian 钱 Sheng-Bang 声 帮 , Wu 吴 Yue 悦 , Zhou 周 Xiao 肖
Published: October 2019

The parameter distribution of binaries is a fundamental knowledge of the stellar systems. A statistical study on the binary stars is carried out based on the LAMOST spectral and Kepler photometric database. We presented a catalog of 1320 binary stars with plentiful parameters, including period, binary subtype, atmosphere parameters (T
eff, [Fe/H], and

), and the physical properties, such as mass, radius, and age, for the primary component stars. Based on this catalog, the unbiased distribution, rather than the observed distribution, was obtained after the correction of selection biases by the Monte Carlo method considering comprehensive affecting factors. For the first time, the orbital eccentricity distribution of the detached binaries is presented. The distribution differences between the three subtypes of binaries (detached, semidetached, and contact) are demonstrated, which can be explained by the generally accepted evolutional scenarios. Many characteristics of the binary stars, such as huge mass transfer on semidetached binaries, period cutoff on contact binaries, period–temperature relationship of contact binaries, and the evolved binaries, are reviewed by the new database. This work supports a common evolutionary scenario for all subtypes of binary stars.
Spiral Structure in the Gas Disk of TW Hya
Authors: Teague Richard , Bae Jaehan , Huang Jane , Bergin Edwin A.
Published: October 2019

We report the detection of spiral substructure in both the gas velocity and temperature structure of the disk around TW Hya, suggestive of planet–disk interactions with an unseen planet. Perturbations from Keplerian rotation tracing out a spiral pattern are observed in the SE of the disk, while significant azimuthal perturbations in the gas temperature are seen in the outer disk, outside 90 au, extending the full azimuth of the disk. The deviation in velocity is either Δv

ϕ
/v
kep ∼ 0.1 or Δv

z
/v
kep ∼ 0.01 depending on whether the perturbation is in the rotational or vertical direction, while radial perturbations can be ruled out. Deviations in the gas temperature are ±4 K about the azimuthally averaged profile, equivalent to deviations of ΔT
gas/T
gas ∼ 0.05. Assuming all three structures can be described by an Archimedean spiral, measurements of the pitch angles of both velocity and temperature spirals show a radially decreasing trend for all three, ranging from 9° at 70 au, dropping to 3° at 200 au. Such low pitch-angled spirals are not readily explained through the wake of an embedded planet in the location of previously reported at 94 au, but rather require a launching mechanism that results in much more tightly wound spirals. Molecular emission tracing distinct heights in the disk is required to accurately distinguish between spiral launching mechanisms.

Published: October 2019

There are few reports on the community composition and diversity pattern of the Cassidinae species of China. Compared to the neighbouring provinces of Guangdong, Fujian and Zhejiang, the Cassidinae richness in Jiangxi Province is under-reported. Longnan City, a biodiversity hotspot in Jiangxi Province, was chosen to obtain the first overview of the Cassidinae beetles. The sample coverage curves for the three sample sites reached an asymptote which indicated sampling was sufficient for data analysis. A total of eight tribes, 16 genera, 59 species and 1590 individuals of Cassidinae beetles were collected. Most belonged to the tribe Hispini (1121 individuals; 70.5%), followed by the tribe Cassidini (161 individuals; 10.13%) and the tribe Oncocephalini (159 individuals; 10.0%). The remainder (149 individuals) belonged to five tribes (Gonophorini, Basiprionotini, Callispini, Notosacanthini and Aspidimorphini). The tribes Notosacanthini, Aspidimorphini and Oncocephalini were newly recorded for Jiangxi Province. There were 14 families, 27 genera and 39 species of host plants of Cassidinae beetles in Longnan County. Cassidinae larvae mainly feed on the plant families Poaceae, Rosaceae, Lamiaceae and Rubiaceae. Most host-plant associations are new reords for the beetle species. This research, together with our planned future work in China, may help to explain the geographical distribution, diversity patterns and host plant associations of these beetles.
Recognizing Delirium Superimposed on Dementia: Assessing Nurses’ Knowledge Using Case Vignettes
Authors: Fick Donna M. , Hodo Denise M. , Lawrence Frank , Inouye Sharon K.
Published: October 2019

Delirium is a serious and prevalent problem that occurs in many hospitalized older adults. Delirium superimposed on dementia (DSD) occurs when a delirium occurs concurrently with a pre-existing dementia. DSD is typically under-recognized by medical and nursing staff. The current study measured nursing identification of DSD using standardized case vignettes, and the Mary Starke Harper Aging Knowledge Exam (MSHAKE). Results revealed that the nurses in this study had a high level of general geropsychiatric nursing knowledge as measured by the MSHAKE, yet had difficulty recognizing DSD compared to dementia alone and delirium alone. Only 21% were able to correctly identify the hypoactive form of DSD, and 41% correctly identified hypoactive delirium alone in the case vignettes. Interventions and educational programs designed to increase nursing awareness of DSD symptoms could help to decrease this gap in nursing knowledge.
Sexuality and Quality of Life
Authors: Robinson Janice G. , Molzahn Anita E.
Published: October 2019

The purpose of this research was to explore the relationships between sexual activity and intimacy and quality of life (QOL) of older adults. The authors' research question was “To what extent do age, gender, marital status, health status, education, satisfaction with personal relationships, sexual activity, and satisfaction with intimacy explain older adults’ ratings of QOL?” A secondary analysis was conducted using results from a cross-sectional survey. Data were available from a convenience sample of 426 individuals living in British Columbia, Canada, who volunteered to complete the questionnaire. Instruments included the WHOQOL-100, WHOQOL-OLD, and a demographic data sheet. It was found that the strongest contributors to the variance of overall QOL were satisfaction with personal relationships, followed by health status and sexual activity. Age, gender, marital status, and education were not significant. The implications for gerontological nurses include the need to support personal relationships for older adults, to encourage health promotion, and to ensure sexuality is discussed with older adults.
Family Participation in Care Plan Meetings: Promoting a Collaborative Organizational Culture in Nursing Homes
Authors: Dijkstra Ate
Published: October 2019

In this study, the author evaluated a project in The Netherlands that aimed to promote family members’ participation in care plan meetings at a psychogeriatric nursing home. The small-scale pilot project, which was conducted in four wards of the nursing home, was designed to involve families in health care decisions by allowing family members to participate in care plan meetings. Both qualitative (participant observation and interview) and quantitative (observation matrix and index analysis) approaches were used to evaluate the project. Findings showed family members were involved in approximately half of the interactions, and many of the questions family members asked were not about the illness, but about its effects. This study indicates there is a need for family members to participate in the multidisciplinary care plan meeting.

Published: October 2019

The word ‘education’ comes from the Greek word ‘educare’ which means carrying out the potentials stored in the children's psyche to be guided in order for them to grow. It involves the dissemination of information or knowledge to, and acceptance by, a student which results in the receiver’s behavioral changes. The “Artist in Schools” (AiS) program was initiated by the researchers and became the platform for the collaboration between schools and artists aimed at increasing the students’ motivation in arts education. It encompasses the sharing of knowledge and experiences between the two groups. This paper is aimed at analyzing the students’ creativity and motivation in visual art by using the ARCS Motivational Model. Using the multi-case studies, nine secondary schools from Peninsular Malaysia were selected as the sample of the study. In-depth interviews, observation, and analysis of related documents were applied. The data were presented narratively. The result revealed that AiS was significantly functional and instrumental in enhancing and encouraging the level of creativity and motivation of the students in visual arts. This study may give a great impact on the students’ development specifically in the learning of visual arts.

The uptake results indicated that the adsorption process was controlled by chemical processes and single-layer adsorption. Due to, the Ca-Al LDH material may be become an effective adsorbent for removal CR dye in aqueous solution.
Modelling of Electrostatic Charge in Ultra-High Precision Diamond Turning of Contact Lens Polymer
Authors: Liman Muhammad Mukhtar , Abou El Hossein Khaled
Published: October 2019

The electrostatic charges encountered by a cutting tool when turning advanced contact lenses are important as they reflect the quality and condition of the tool, machine, fixture, and sometimes even the surface finished which is responsible for tool wear and poor surface quality. This study investigates the influence of cutting parameters namely cutting speed, feed rate and depth of cut on electrostatic charge (ESC) which play the leading role in determining the machine economics and quality of machining contact lens polymers. An electrostatic charge model based on response surface statistical method is developed for reliably predicting the values of static charging based on its relationship to cutting parameters in ultra-high precision diamond turning of contact lenses. It is clearly seen that all the model terms are significant with cutting speed having the highest degree of significance followed by feed rate and the interaction of speed and feed. However, depth of cut has the lowest degree of significance on the electrostatics charge.
Study on the Interface of Acetylene Silazane (SZ) Modified QF/PSA Composites
Authors: Zhou Xiao Yi , Zhou Yan , Deng Shi Feng
Published: October 2019

Due to the excellent thermo-stability, ablation resistance and superior dielectric properties, poly-silicon-containing arylacetylene resin (PSA) shows a promising application in aerospace and spaceflight industries as a composite matrix with quartz fiber (QF). However, the non-polar nature of PSA hamper the interfacial interaction with the QF resulting in a relatively weak mechanical strength for the whole QF/PSA composites. This can be alleviated by incorporating a coupling agent between QF and PSA to reinforce their interaction. Here, new coupling agents, three ethynyl silazane derivatives, were synthesized to improve QF/PSA composite mechanical properties and named as bis (3-ethynylaniline)-diphenylsilane (SZPP), bis (3-ethynylaniline)-methylphenylsilane (SZMP) and bis (3-ethynylaniline)-phenylvinylsilane (SZPV). For SZPP, about 3.0 wt% addition of this coupling agent increased the interlaminar shear strength and flexural strength of QF/PSA composite by 21.2% and 18.4%, respectively, compared with the untreated composite. Meanwhile, among the three coupling agents, SZPV showed the best improvement in enhancing the interlaminar shear strength and flexural strength of QF/PSA composites, which reached 34.1% and 41.7%, respectively.
Possible Ferromagnetism in YCuO System
Authors: Xu Gong Qin , Chen Xiao Wei , Mao Xing Yu
Published: October 2019

polycrystalline CuxYyOz are made through solid state reaction. Ferromagnetism is found in this YCuO system at room temperature. The ferromagnetism quite probably originates from Cu2Y2O5 , the Copper Yttrium Oxide. The average magnetic moment per Cu2+ is estimated to be 0.04μB. Itinerant electron magnetism is a rational explaination for the observed ferromagnetism. The experiment shows that the excessive amount of Cu may lead more defects and further distortion in the lattice and decrease the exchange interaction. This reminds us that the Copper Yttrium Oxide is a substance not only should be avoided in fabricating YBCO superconductors but also should be considered as a potential substance of magnetic semiconductor.
Development of the Snoek Anelastic Relaxation Correlated with Oxygen in β-Ti Alloys
Authors: Zhou Zheng Cun , Du J. , Gu S.Y. , Yan Y.J.
Published: October 2019

The β-Ti alloys exhibit excellent shape memory effect and superelastic properties. The interstitial atoms in the alloys have important effect on their physical and mechanical properties. For the interstitial atoms, the internal friction technique can be used to detect their distributions and status in the alloys. The anelastic relaxation in β-Ti alloys is discussed in this paper. β-Ti alloys possesses bcc (body center body) structure. The oxygen (O) atoms in in the alloys is difficult to be removed. The O atoms located at the octahedral sites in the alloys will produce relaxation under cycle stress. In addition, the interaction between the interstitial atoms and substitute atoms, e.g., Nb-O,Ti-O can also produce relaxation. Therefore, the observed relaxational internal friction peak during the measuring of internal friction is widened. The widened multiple relaxation peak can be revolved into Debye,s elemental peaks in Ti-based alloys. The relaxation peak is associated with oxygen movements in lattices under the application of cycle stress and the interactions of oxygen-substitute atoms in metastable β phase (βM) phase for the water-cooled specimens and in the stable β (βS) phase for the as-sintered specimens. The damping peak height is not only associated with the interstitial oxygen, but also the stability and number of βM in the alloys.

This is the first case described in the literature of cannonball lung metastases from adrenocortical tumor in a man.
Formative assessment as ‘formative pedagogy’ in Grade 3 mathematics
Authors: Govender Poomoney
Published: October 2019

Background: Formative assessment, as an integral component of teaching, has recently gained prominence in educational environments globally. Poor performances in mathematics by learners in early grades, and its negative effect on later learning, have been an ongoing concern in South African schools. Several former studies tend to generalise the pedagogical reasons for learners’ underperformance in Foundation Phase teaching.Aim: This case study of selected Grade 3 teachers examined how the teachers integrated formative assessment into their pedagogy, with the purpose of gaining insight into teachers’ understanding of the developmental aspects of learning in mathematics.Setting: This study was conducted at four schools in a selected district in the Gauteng Province.Methods: Data were mainly collected through focus group interviews and observations of at least three classroom sessions for each teacher of mathematics, thereby gaining an overview of their formative assessment practices.Results: This article reports on the two strongest themes to have emerged from the case study, which were teachers’ tokenistic use of ‘Assessment for Learning’ strategies and teachers’ awareness of learning processes and curriculum requirements.Conclusion: The study’s main conclusion was that teachers are likely to practise formative assessment more intuitively if they had a sound knowledge of children’s mathematical cognition and conceptual development. This study pointed out that formative assessment is a co-constructed activity involving the teacher, the learner and peers rather than a teacher-directed activity. The study recommends how continuous professional learning initiatives can design initiatives that integrate research-based knowledge of children’s learning of early grades mathematics.

Inter cell interference modeling and analysis in long term evolution (LTE)
Authors: Alemayehu Bekele , Gared Fikreselam
Published: October 2019

Long Term Evolution (LTE) is promising standard for data rate and system capacity (coverage) in wirelesses communication history. Inter cell interference (ICI) is a dominate impairment of LTE systems. In interference, modeling and analysis have focused on the first tier only, but considering ICI arises from the second tier is very crucial in communication system standard and implementations too. In this research work interference modeling is proposed and analyzed for the first two subsequent tires under various channel environments. The work is analytically quantified with respect to standard parameters and system models using Matlab and other supportive tools. Thus, link level simulation results demonstrate, ICI beyond the first tier becomes active in urban environment and the smaller cell size increases ICI power in LTE.
As constituições latino-americanas entre a vida e a morte : possibilidades e limites do poder de emenda
Authors: Barroso Luis Roberto , Osorio Aline
Published: October 2019

O presente artigo tem como objetivo discutir a relação entre emendas constitucionais, cláusulas pétreas e a durabilidade de uma constituição, tendo como foco o cenário latino-americano. Para que uma constituição não perca o compasso da história, é necessário que alcance um equilíbrio entre permanência e plasticidade, o que, comumente, manifesta-se nos processos de emendas constitucionais e identificação de núcleos constitucionais essenciais, por vezes protegidos por cláusulas pétreas. Sendo essas cláusulas contramajoritárias, idealmente devem ser interpretadas de maneira restritiva, o que justifica uma cuidadosa análise de como o poder judiciário vem compatibilizando-as com o poder constituinte derivado. No caso específico do Brasil, é possível perceber que o alto número de emendas não ocasionou alterações significativas ao seu núcleo essencial e que o Supremo Tribunal Federal é mais tendente a restringi-las quando versam sobre matéria formalmente constitucional, afastando-se de interpretações ampliativas das cláusulas pétreas

Complications After Pediatric Hip Fractures: Evaluation and Management
Authors: Lark Robert K. , Dial Brian L. , Alman Benjamin A.
Published: October 2019

Pediatric proximal femur fractures are high-energy injuries with predictable and morbid complications. Osteonecrosis of the femoral head is the most common complication with identified risk factors including fracture type, patient's age, degree of displacement, timing to reduction, and stability of fixation. Additional complications include nonunion, coxa vara, and premature physeal arrest. The mainstay of treatment for traumatic pediatric osteonecrosis is hip preservation with total hip arthroplasty being reserved as a salvage procedure. An anatomic fracture reduction and a biomechanically stable construct are critical to prevent both nonunion and osteonecrosis. This review will look at the individual surgical interventions for the management of the associated complications of pediatric proximal femur fractures.
Immunophenotype Study in Children with Leukemia and Its Relationship with Relapse in Ahvaz Shafa Hospital from 2013 to 2018
Authors: Alghasi Arash , Safdarian Jamshid
Published: October 2019

Introduction: Acute lymphoblastic leukemia (ALL) is one of the most common cancers in children. Since the identification of patients immunophenotypes is effective for disease diagnose and prognosis, and due to very few studies in Iran, especially Khuzestan province, the aim of this study was to investigate the immunophenotype of children with leukemia and its association with recurrence in Ahvaz Shafa Hospital from 2013 to 2019.

Methods: This is a retrospective study that was conducted in patients referring to Ahvaz Shafa Hospital during the years 2013 to 2019. Demographic data including age, gender, height, weight, leukocyte count, flow cytometry and other laboratory findings were collected and analyzed by version 22 SPSS statistical software.

Results: The mean age of the patients was 7.59 ± 3.94 years and the sex of 51 (52%) were female. Immunophenotype of 81 patients (82.7%) was Pre B cell, 4 patients (4.1%) was Pro-B Cell, 5 patients (5.1%) was Pro-T Cell, and 8 patients (8.2%) was T Cells. 87 patients (88.8%) recovered and 11 patients (11.2%) had recurrence. Only 11 patients with Pre B cell (13.6%) had recurrence, but in other immunophenotypes, 100% of patients had remission, but this difference was not statistically significant (p = 0.46). There was no statistically significant difference between the prevalence of phenotypes in female and male sexes (p = 0.76). The incidence of recurrence was 9.8% in female patients and 12.8% in male patients, which was not statistically significant (p = 0.64).

Conclusion: The results of this study showed that preB cell immunophenotypes with the prevalence of 82.7% had the highest frequency in acute lymphoblastic leukemia, and the incidence of recurrence in patients was 11.2%. Also, patients with other immunophenotypes did not recurrence, so his finding may have been because of insufficent patients to study and compare.

Euthanasie bij een verlaagd bewustzijn: de richtlijn en de praktijk

Volgens de KNMG-richtlijn uit 2010 kan euthanasie bij een verlaagd bewustzijn alleen worden uitgevoerd als bij de patiënt nog tekenen van ernstig lijden waarneembaar zijn, of als de bewustzijnsverlaging het onbedoelde gevolg is van medicatie en dus in principe reversibel. Hoewel de richtlijn dat niet aangeeft zijn deze criteria ook van toepassing wanneer de bewustzijnsverlaging intreedt door opzettelijke sedatie op een moment dat de euthanasie nog niet kan worden uitgevoerd. De richtlijn bespreekt evenmin de situatie waarin de bewustzijnsverlaging intreedt voor het bezoek van de consulent. De toetsingscommissies gaan er nu van uit dat in dat geval toch aan het wettelijk consultatievereiste kan zijn voldaan. Dat de consulent echter niet uit eigen waarneming kan vaststellen of aan de wettelijke zorgvuldigheidseisen is voldaan, zou ertoe moeten leiden dat op de meldend arts een zwaardere bewijslast rust om aannemelijk te maken dat dit toch het geval is.

VPH en dwangpsychiatrie: hoe verder?

VPH en dwangpsychiatrie: hoe verder? Een aanzet voor een principieel debat

Vanuit VN-verband is aangegeven dat de regulering van dwangpsychiatrie zoals die in Nederland bestaat in het kader van de Wet Bopz en haar beoogde opvolgster, de Wvggz, strijdig is met het door Nederland geratificeerde VN-Verdrag inzake de rechten van personen met een handicap (VPH). Deze strijdigheid is vanuit het kabinet echter ontkend. Bij beide visies worden kanttekeningen geplaatst, waarna twee varianten voor een mogelijke alternatieve dwangregeling bespreking vinden. In de bedoelde varianten bestaat minder wrijving met het VPH en de noties die aan dit verdrag ten grondslag liggen, doordat het begrip ‘geestesstoornis’ daarin geen deel uitmaakt van de juridische criteria ter rechtvaardiging van dwang, te weten 1) wilsonbekwaamheid of 2) gevaar ‘sec’.
De wilsbekwame patiënt en zijn mentor of curator

De wilsbekwame patiënt en zijn mentor of curator

De mogelijkheid bestaat dat een patiënt die een mentor of curator heeft op enig moment wilsbekwaam is met betrekking tot beslissingen over medisch handelen. Wie beslist dan: de patiënt of zijn wettelijk vertegenwoordiger? Over het antwoord op die vraag wordt in het gezondheidsrecht verschillend gedacht. In dit artikel wordt betoogd dat voor de mentor of curator alleen een rol is weggelegd op momenten dat de patiënt wilsonbekwaam is.

Euthanasie bij gevorderde dementie: een belangrijke uitspraak

Bespreking van de eerste uitspraak van een tuchtcollege inzake euthanasie bij een diep-demente patiënt. RTG Den Haag acht euthanasie in beginsel toegestaan maar stelt hoge eisen aan het schriftelijke euthanasieverzoek en aan de communicatie tussen arts en patiënt. Volgens de schrijver heeft het tuchtcollege onvoldoende rekening gehouden met de wetsgeschiedenis.

Teatro do Oprimido na Educação em Design de Interação
Authors: M.C. van Amstel Frederick
Published: October 2019

A pesquisa sobre Educação em Design de Interação têm apontado para a necessidade de rever a prática reflexiva do ateliê de projetos frente ao uso crescente do material digital para intensificar opressões. Dentre as pedagogias críticas que estão sendo consideradas para trabalhar com esse fenômeno, o Teatro do Oprimido oferece um arsenal de técnicas para encenar, analisar, criticar e mudar situações cotidianas que reiteram opressões históricas entre grupos sociais. Essas técnicas permitem envolver ativamente o corpo no processo pedagógico, além de promover a criatividade estética e a participação democrática. Mais do que isso, revelam a dimensão política do projeto de interação e seu potencial para lutar contra a opressão.
Engenharia semiótica e arte digital interativa: Um estudo da autoexpressão do artista-designer

Published: October 2019

No final do século XX, com a popularização da internet, obras de arte digital interativa ganharam um novo espaço de disseminação, intervenção e criação. Nesse contexto, a internet permite e exige a participação da audiência como uma parte importante de muitas dessas obras, construídas como sistemas ou artefatos computacionais interativos. Neste pôster, apresentamos a aplicação de conceitos da Engenharia Semiótica na análise de três obras de arte digital e interativa desenvolvidas e publicadas na Web entre 1996 e 2003, Mouchette, Life sharing e My boyfriend came back from the war (MBCBFTW). Este estudo teve o objetivo de investigar como se manifesta a metacomunicação do artistadesigner do sistema, que, nesse contexto, é o autor da obra. Para isso, reconstruímos e comparamos a metamensagem das três obras, observando o que o designer comunica sobre o usuário, o sistema e sobre ele mesmo. Como resultado, observou-se que a quantidade e a qualidade das mensagens variaram entre as obras. Apresentamos uma discussão sobre como a Engenharia Semiótica pode dar suporte à análise de obras de arte digitais e interativas.

O Picolê é um sistema multiplataforma que permite o cadastro e a administração de pessoas, agendas e atividades de instituições do terceiro setor, bem como permite a autoria de atividades terapêuticas e pedagógicas por parte de profissionais da saúde e educação. As atividades podem ser criadas por esses profissionais por meio de uma interface baseada em templates pré-definidos e que são apresentados em dispositivos móveis para usuários alvo desses profissionais. As atividades são lúdicas e podem ser mais atrativas do que as atividades em papel. O sistema foi desenvolvido de modo participativo, com diferentes partes interessadas envolvidas no processo de design e avaliação. Atualmente o sistema está em uso em uma ONG da cidade de São Carlos/SP. Resultados parciais apontam relatos positivos dos profissionais que estão usando o sistema em suas atividades diárias.

Published: October 2019

A sinergia entre universidade e mercado de trabalho é um dos objetivos do Desafio 5 do GrandIHC-BR: Formação em IHC e Mercado. Entretanto, ainda hoje as oportunidades de cooperação entre estas duas esferas são raras. Desta forma, este artigo visa contribuir com um exemplo de articulação entre uma disciplina de Avaliação em Interação Humano-Computador com uma demanda da indústria que presta serviço a um governo municipal. Um sistema de atendimento ao cidadão foi avaliado por uma turma de graduação por meio de métodos de inspeção e métodos de observação. Os resultados das avaliações foram compartilhados com a empresa que presta serviço para a prefeitura e as correções necessárias já foram realizadas. Ao compartilhar esta experiência pretende-se ilustrar como pode ser possível estabelecer interlocução com o mercado de trabalho.
Investigando Curadoria Coletiva em um Contexto Científico de Compartilhamento de Métodos e Modelos
Authors: Ferreira Lídia , Prates Raquel
Published: October 2019

Este trabalho tem por objetivo investigar estratégias de curadoria coletiva no contexto científico, ou seja, analisar como as pessoas colaboram entre si para fazer a seleção de um determinado tipo de informação e como um sistema pode intermediar essa interação. Uma vez que tais estratégias sejam identificadas, deseja-se fazer um estudo exploratório para avaliar tanto a estratégia quanto a sua aplicação por um sistema. Para isso, espera-se implementar as estratégias de curadoria em um estudo de caso no contexto de métodos de avaliação de sistemas usando o StoreAnt, um repositório de caracterização de métodos, como base para aplicação e validação das estratégias de curadoria investigadas. Isso provê como resultado contribuições teóricas e práticas. Como contribuições teóricas tem-se principalmente os resultados da investigação sobre estratégias de curadoria coletiva, de forma consolidada, além de critérios de busca, caracterização e comparação em um contexto específico de métodos de avaliação. Hoje esse é um tema pouco explorado na área de IHC e com grande potencial para a comunidade, uma vez que impacta diretamente nos mecanismos de consolidação dos trabalhos publicados. Como contribuição prática, tem-se os resultados do estudo de caso e a consolidação da ferramenta StoreAnt, que poderá ser utilizada pela comunidade para intermediar a curadoria de um determinado tipo de conhecimento.
