Authors: Saidi Subian , Muharramah Ulfah , Zakaria La , Mariska Yomi , Ruby Triyono
Published: June 2020

The Lorenz curve is generally used to find out the inequality of income distribution. Mathematically a standard form of the Lorenz curve can be modified with the aim of simplicity of its symmetric analysis and calculation of the Gini coefficient that usually accompanies it. One way to modify the shape of the Lorenz curve without losing its characteristics but is simple in the analysis of geometric shapes is through a transformation (rotation). To be efficient and effective in computing and analyzing a Lorenz curve it is necessary to consider using computer software. In this article, in addition to describing the development of the concept of using transformations (rotations) of the standard Lorenz curve in an easy-to-do form, the symmetric analysis is also described by computational techniques using Mathematica® software. From the results of the application of the development of the concept of the Lorenz curve which is carried out on a data gives a simpler picture of the computational process with relatively similar computational results.

Moreover, logistics technology involves close interaction with other departments at various stages of work with external contractors.
In Vitro and In Vivo Test of Boron Delivery Agent for BNCT
Authors: Wijaya Sista Dyah , Poedjomartono Bagaswoto , Sardjono Yohannes
Published: June 2020

BNCT is an alternate therapy for treating cancer. The principle of BNCT involves a neutron boron uptake and a fission reaction that produce alpha particles and Li ions with a high level of linear energy transfer in the tissue. It is effective in killing tumor cells. To administer boron in the tumor cells, a boron delivery agent is needed. Thus far, there are a variety of boron delivery agents that have been developed. To date, just two main boron-based drugs, BPA and BSH, have been used for clinical studies. Many other boron delivery agents have been evaluated in vivo and in vitro but have not been evaluated clinically. Therefore, the other boron delivery agents have not been used in BNCT clinical studies.

Persepsi dan Kesiapan Mengajar Mahasiswa Guru Terhadap Anak Berkebutuhan Khusus dalam Konteks Sekolah Inklusi
Authors: Wardhani M. Kusuma
Published: June 2020

The implementation of inclusive education in reality, really requires readiness and support from various parties, including fron the educators who are ready in the sense of being able and willing to educate children with special needs. The focus of this study is to examine the perceptions of pre-service teachers in Pelita Harapan University for children with special needs who have access to inclusive education, and what factors underlie these perceptions. The next focus is whether the pre-service teachers have the readiness or vice versa just that there is still doubt or reluctance to teach in inclusive schools. The research method is qualitative descriptive. The number of respondents was one class consisting of 40 students which was a combination of 2 two study programs. The results showed that pre service teachers had perceptions that children with special needs could attend school in inclusive schools, and will be successfull. The arguments that underlie these perceptions are three things: the equal right to education for everyone; curriculumadjustment, teaching methods, assessments and facilities for students with special needs; inclusive schools are a combination of public schools with special schools, and adjustments for each child with special needs in the form of PPI (Individual Development Program). All respondents stated their readiness to teach in inclusive schools. The reason are because a teacher should treat his student equally, the subject of Teaching Student With Special Ability courses has equipped them, and adjustments made in inclusive schools in terms of methods, curriculum, assessment and infrastructure.

DEVELOPMENT OF AN INTERACTIVE ONLINE ETHICS SCENARIO ACTIVITY FOR ENGINEERING STUDENTS
Authors: Ostafichuk Peter M. , P. Jaeger Carol , Nakane Jonathan
Published: June 2020

This paper describes development and deployment of an online interactive ethical decision-making simulation.  This tool was piloted in a first-year introduction to engineering course at the University of British Columbia.  It used a “choose your own adventure” style of decision-making and narrative to add realism and engagement to what was otherwise viewed by students as dry, uninteresting content.  After storyboarding using sticky notes and Visio, the final tool used by students was implemented and deployed using a survey tool (Qualtrics). It featured a scenario with initially incomplete information and the appearance of unethical behaviour by others.  It included decision-based branching, but also randomization such that different groups had the story unfold differently, even if they made the same initial decisions.  Student feedback on this tool was very positive, suggesting this style of interactive online ethics simulation could be an effective tool for enhancing engagement and learning.

Authors: Paul Robyn , Nightingale Miriam , Ismaguilova Alina , Behjat Laleh , Di Martino Elena , Sun Qiao
Published: June 2020

Diversity in engineering is a key goal, however a barrier for students from diverse backgrounds is the physics requirements in engineering. Often, they will have to choose between the three sciences, and don’t realize that without physics, their options are limited. We launched a pilot program in 2019 to expand access into engineering. Students without high school physics can take a summer bridge program to teach them the fundamentals and prepare them for first year engineering. Physics is taught through bioengineering to leverage their biology background knowledge. This paper presents a thematic analysis of student reflections in the program, using student identity development as a framework.
LEGO SERIOUS PLAY AND THE GRADUATE ATTRIBUTES
Authors: Balakrishnan R. , Seniuk Cicek J. , Mani P. , Mann D.
Published: June 2020

As part of a longitudinal project to integrate career development supports into a biosystems engineering classroom, students engaged in a LEGO© Serious Play workshop and wrote reflections on their experiences. This workshop provided opportunities for teambuilding and deliberations on what constitutes a strong team. A constructivist grounded theory analysis of students’ reflections was conducted.  Through this analysis, a preliminary theme of Perceptions of Engineering Skill emerged, with three subthemes of the necessity of teamwork and communication to engineering; the vulnerability in making interpersonal connection; and the explicit connection of engineering to creativity. These skills can be conceptualized within the CEAB graduate attributes and theorized within the systems theory framework (STF) of career development, which positions the students’ skill development within the larger context of their career. Ultimately, the preliminary findings of this study provide a starting point for further analysis, and for the development of an interview protocol for the longitudinal study this project sits within, with the overarching goal to investigate the impact of career supports and process of career development in a professional degree program.

Published: June 2020

The exposure to matters related to sexuality and pornography makes sexuality education for elementary students an important thing to do. The goals are to equip and empower young people with the information, skills and positive values, and to make young people understand and responsible for their sexuality health and wellbeing. Cases relating to the issue of sexuality have begun to appear in students of grade 4-6 at SD N, but teachers appear not to have fully applied sexuality education to their students. This study aims to get an idea about teacher’s intention, included teacher’s attitude toward behavior, subjective norm, and perceived behavior control in teaching sexuality to grade 4-6 students. The research design used in this study is mixed-method design. The number of participants of this study are 20 people (50% male and 50% female) with age range from 24 years old to 42 years old. The results showed that the majority of teachers (55%) have moderate intention, high attitude toward behavior (80%), moderate subjective norm (80%) and moderate perceived behavior control (65%). The results also showed that only perceived behavior control has a significant relationship with the intention (r= .617, p<0.05).

Authors: Zieliński Marcin
Published: June 2020

The results of Zarzycki for the cardinality of the sets of all bijections, surjections, and injections are generalized to the case when the domains and codomains are infinite and different. The elementary proofs the cardinality of the sets of bijections and surjections are given within the framework of the Zermelo-Fraenkel set theory with the axiom of choice. The case of the set of all injections is considered in detail and more explicit an expression is obtained when the Generalized Continuum Hypothesis is assumed.

Espacio público y vendedores informales afrocolombianos en Cali, Colombia
Authors: Nunez Basante Pamela
Published: June 2020

El 25.5% de todos los afrodescendientes en Colombia residen en la ciudad de Cali, lo que representa el 26% de la población total de la ciudad. De esta manera, Cali es una de las ciudades con mayor población afrocolombiana del país. La ciudad ha sido el principal centro de atracción para las poblaciones migrantes de la costa del Pacífico Sur de Colombia en la que prevalece la población afrocolombiana. La venta informal en Cali es llevada a cabo principalmente por migrantes rurales y/o desplazados internos. En este artículo, me interesa saber si los afrocolombianos sufren una mayor marginalidad y discriminación como vendedores ambulantes que los auto identificados como mestizos y blancos o si, por el contrario, ambos grupos enfrentan niveles similares de discriminación. Por lo tanto, propongo averiguar si los cuerpos negros están marcados por discursos de indeseabilidad y crimen en los espacios públicos de esta ciudad. Adicionalmente, este fenómeno es entendido por los académicos urbanos, así como por el gobierno de Cali como una lucha de clases. Esta comprensión ratifica la invisibilidad de los cuerpos racializados negros en los discursos de igualdad. Muchos autores afirman que el problema actual en Colombia de reconocer la composición racial diversa de los vendedores informales y entender estas luchas sólo a través de las clases impide un discernimiento bien pensado de las realidades sociales y económicas que enfrentan los cuerpos racializados en los espacios públicos.
El desastre de Salgar en Teleantioquia Noticias: narrativas mediáticas, rasgos institucionales y estrategias de reconocimiento para las audiencias
Authors: Hermelin Daniel , Villegas Andrés
Published: June 2020

Este trabajo hace un análisis del tratamiento que le dio el noticiero Teleantioquia Noticias a la avenida torrencial que afectó gravemente al municipio de Salgar (Colombia), en mayo de 2015. Con base en una muestra de emisiones y en información exógena, se hace una aproximación a las condiciones de producción y a la convergencia mediática que propone el noticiero. Se usan elementos de análisis semio-discursivo para entender el trasfondo narrativo del cubrimiento de esta catástrofe. Se observa que el gobierno departamental marca con fuerza la agenda del noticiero en este acontecimiento; que las narrativas del medio apelan a diversas formas de reconocimiento de las audiencias, especialmente la invitación a la “cooperación digital”; y que el noticiero propone enganches a los destinatarios mucho más centrados en las consecuencias del desastre que en sus causas. Esto muestra limitaciones y oportunidades relevantes para la comunicación de la gestión del riesgo de desastres.
Periodismo de Datos en la transición al posconflicto en Colombia
Authors: García Kevin Alexis , González Mina Julián
Published: June 2020

Este artículo sustenta la hipótesis de que está emergiendo en Colombia un tipo especial de producción de periodismo de datos en el periodo de transición hacia el posconflicto armado. Mediante documentación bibliográfica y análisis exploratorio, se analizan seis proyectos de periodismo de datos, producidos por medios migrados y emergentes en internet que tienen como perspectiva central temáticas relacionadas con el conflicto. Se analiza en qué medida dichos proyectos entrañan una renovación y reconfiguración de las prácticas periodísticas usuales. El examen de los proyectos ha permitido identificar cuatro figuras de información a partir de los datos: 1. Procesos de geo y crono referenciación de eventos, 2. Visualización de contrastes y comparaciones, 3. Representación de vínculos de poder mediante grafos o redes, y 4. síntesis gráfica de información. A través del examen de los resultados se destacan los avances de estas iniciativas y se propone revisar el paradigma de interactividad en los medios. Se enfatiza que la débil exploración de la interactividad profunda offline/online es un desafío crucial para el desarrollo de medios de comunicación de nuevo y viejo tipo.

El artículo presenta algunas reflexiones relacionadas con la práctica del Parkour en el contexto urbano de Cali, desde una perspectiva interpretativa, da cuenta de las tensiones de algunos valores sociales como: disciplina - libertad, rutina - improvisación, riesgo - control; ocasionadas en el cambio de paradigma y pasaje de la modernidad a la posmodernidad y reflejadas en el cuerpo de los practicantes. Para ello, se realizó un acercamiento etnográfico desde la observación participante de los elementos constitutivos del Parkour, complementando con notas de campo, entrevistas, consulta de páginas virtuales oficiales de los grupos y fotografías de la práctica. Al finalizar, se sugiere, que el Parkour propicia cuerpos dóciles, desarrolla una técnica que permite realizar desplazamientos urbanos eficaces soportados en la hexis corporal, lo cual conlleva a un habitus y desgaste que procura sentido a los trazadores, porque el cuerpo se transforma en un vehículo y mecanismo de anclaje de experiencias óptimas.

Published: June 2020

Esse artigo buscou discorrer sobre a motivação para a aprendizagem em crianças escolares. A motivação relacionada ao processo educacional tem sido alvo de muitas pesquisas nacionais e internacionais, principalmente com o decorrer dos anos. Isto, porque, esta é uma relevante variável a ser investigada quando se trata do processo de ensino aprendizagem, pois, sua ausência tem sido atribuída a uma queda de investimento pessoal do estudante na realização das tarefas solicitadas pelo professor, pouca participação nas aulas, pouco tempo dedicado aos estudos e possível afastamento do processo de aprendizagem. Ou seja, a motivação é fundamental na vida dos estudantes por interferir no comportamento dos estudantes frente às questões educacionais, e, por isso, tem sido tão discutida na literatura nacional e internacional. A motivação é uma variável de grande importância por exercer influência no comportamento dos estudantes diante dos desafios a eles propostos, e deste modo, afetar o processo de aprendizagem deles.

Authors: Merai Hema , Collas David , Bhagat Ashish , Mandalia Uday
Published: June 2020

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans’ cell histiocytosis characterized by xanthogranulomatous infiltration of foamy histiocytes surrounded by fibrosis. ECD may be asymptomatic or present as a multi-systemic disease with life-threatening manifestations, most commonly involving the skeletal system. Immunohistochemical staining demonstrates cells that are CD68+, CD1a–, and S100– with an absence of Birbeck granules. We report a case of a 69-year old male patient who presented with neurological symptoms – eventually thought to be separate to his diagnosis of ECD. It represents the ability to diagnose ECD based just on radiological findings in an otherwise asymptomatic individual.
A new disaggregation induced emission enhancement (DIEE)based probe for cellular detection of copper and lactate

Published: June 2020

We report self assembling/aggregation properties of acyl-thiourea derivative, N-((6-methoxy-pyridin-2-yl)carbamothioyl)benzamide(NG1) [i1] and the disaggregation induced emission which leads to its application as fluorescence and colorimetric probe for the sensitive detection of Cu2+. The microscopy analysis of NG1via SEM, and AFM reveal that it self-assembles to give fiber-like morphologies.Interestingly,NG1 also assembles to fluorescent fibers which show tunable emission properties. Addition of Cu2+to these fibers causedisruption/disaggregation of fibers and a golden yellow fluorescence is produced due to disaggregation induced emission enhancement (DIEE). The application of NG1 as selective sensor for copper was further assessed by UV visible and fluorescence spectroscopy. Limit of Detection(LOD) of Cu2+ with colorimetry was 2.5ppm while LOD of Cu2+ with fluorescence was as low as 0.1ppm. This yellow fluorescence is quenched after the addition of lactic acid and hence NG1 could potentially be used for the sequential detection of both Cu and lactate.Further, structural modification of the probe NG1 suggest crucial role of both pyridine and acyl-thiourea moiety in the binding of Cu2+. The experimental results of interaction of NG1 with Cu2+ and lactate were also validated theoretically by quantum chemical calculations based on density functional theory (DFT). Finally, we explore the ability of NG1for the sequential detection of Cu2+ and lactate in cells, which suggestsNG1 can be used effectively for the cellular imaging applications and to selectively sense Cu2+. To, the best of our knowledge, this is the first report wherein a dual sensor for Cu2+and lactate ion is synthesized and it may in allpossibilities pave the way for the diagnosis of Cu2+associated disorders like Wilson’s disease and in the detection of elevated lactate levels which are associated with the wide range of pathologies likemitochondrial diseases, cerebral ischemia and cancer.

Considering the importance of ayurvedic herbs, science behind their potential in treating diseases and advantages over synthetic medicines in limiting side effects, there is an urgent need to employ such sacred science to produce medicines that effectively cure diseases and to distribute them to the needy. Many herbs mentioned in ayurveda are used to treat dreadful hepatic diseases especially, cirrhosis which is caused by the liver damage due to toxins, chronic alcoholism, synthetic drugs etc. In the present study, poly herbal hepatoprotective formulation, LIVAFIT, had been prepared and standardized for determining its quality and safety. Methanol herbal extracts were formulated according to a formula with Phyllanthus neruri, Picorrhiza kurroa, Andrographis paniculata as active ingredients and various other herbs helpful for possible hepatic regeneration and preventing hepatotoxicity. Physico chemically, microscopically and chemically standardized extracts were used in the study. Following the results of acute toxicity studies and after confirming the safety of extracts, hepatoprotective activity of formulation was evaluated by CCL4 induced hepatotoxicity method in albino wistar rats. It exhibited a dose dependent significant (P<0.001) reduction in hepatotoxicity when compared with that of standard, Silymarin and a pre-marketed ayurvedic product.

DM otherwise diabetes is now a days an epidemic with the percentage of patient population rising to almost 10% of the world population. Out of all the DM complications, cataract leads the way contributing to disabilities to about 60% of diabetic population. But the pathogenesis of DM cataract is still a half-understood area of medicine there by posing a problem in the therapy. The data that we have till now gives us enough evidence to advocate the oxidative stress has a major role for the pathogenesis of DM complications like DMnephropathy, DMneuropathy, and cardiac hypertrophy, which suggests the oxidative stress is a central feature of diabetes. In the current research, the pharmacological evaluation of Fisetin for its DM based anti-cataract property was performed. This research concentrates to estimate the possible involvement of Nrf-2 / heme oxygenase (HO)-pathway in the observed therapeutic effect, if any. The data obtained in this study also indicate that the observed beneficial effects mainly due to activation of Nrf2/HO-1 pathway. These effects probably result in increased tissue anti-oxidant status as well as decreased free radical production, which ultimately responsible for the observed beneficial effects of Fisetin against hyperglycemia-induced cataract.
Development of the red algal parasite Vertebrata aterrimophila sp. nov. (Rhodomelaceae, Ceramiales) from New Zealand

© 2019, © 2019 British Phycological Society. Parasitic red algae grow only on other red algae and have over 120 described species. Developmental studies in red algal parasites are few, although they have shown that secondary pit connections formed between parasite and host and proposed that this was an important process in successful parasitism. Furthermore, it was recorded that the transfer of parasite nuclei by these secondary pit connections led to different host cell effects. We used developmental studies to reconstruct early stages and any host cell effects of a parasite on Vertebrata aterrima. A mitochondrial marker (cox1) and morphological observations (light and fluorescence microscopy) were used to describe this new red algal parasite as Vertebrata aterrimophila sp. nov. Early developmental stages show that a parasite spore connects via secondary pit connections with a pericentral host cell after cuticle penetration. Developmental observations revealed a unique connection cell that grows into a ‘trunk-like’ structure. Host cell transformation after infection by the parasite included apparent increases in both carbohydrate concentrations and nuclear size, as well as structural changes. Analyses of molecular phylogenies and reproductive structures indicated that the closest relative of V. aterrimophila is its host, V. aterrima. Our study shows a novel developmental parasite stage (‘trunk-like’ cell) and highlights the need for further developmental studies to investigate the range of developmental patterns and host effects in parasitic red algae.

We use data from motion-activated remote cameras to document a commensal, and possibly mutualistic, relationship between Bornean Ground Cuckoos and Bearded Pigs in the rainforests of Kalimantan, Indonesia. We hypothesise that birds benefiting from symbiotic relationships may suffer indirect detrimental effects from hunting that targets large mammals in tropical rainforests.

Tədqiqatın məqsədi Azərbaycanda rast gəlinən kirpi növlərini morfologiyasını, bioekoloji xüsusiyyətlərini, respublikamızın teriofaunasındakı taksonomik statusunu müəyyənləşdirməkdir.

Tədqiqatın material və metodları: Material olaraq, Azərbaycan respublikasının müxtəlif regionlarından toplanan kirpilərdən  istifadə  olunmuşdur.  Tədqiqat  nəticəsində  alınan  məlumatlar  N.A.  Ploxinskiy  və  E.V.  İvanter,  A.V. Korosovaya görə hesablanaraq bioloji və riyazi xətaları azaldılmışdır. Stasionar tədqiqat ərazilərində kirpilərin rast gəlmə tezliyi Rafkinə ğörə verilən düsturla hesablanıb. Növü təyin edərkən Pavlinov və b-nın irəli sürdükləri morfofizioloji indikator metodundan istifadə edilmişdir.

Tədqiqatın nəticələri: Qulaqlı kirpi maksimum çəki artımına qış yuxusuna getməzdən öncə çatırlar, bu məsələdə də cinsi dimorfizm özünü göstərir. Qulaqlı kirpinin kəlləsinin kranioloji ölçüləri bölgələrdən asılı olaraq, xarakter formada dəyişir və minimum ölçü ilə maksimum ölçü arasında kifayət qədər fərq müşayiət olunur. Postnatal inkişafın erkən dövründə tikanların sürətlə inkişafı və tez bir zamanda codlaşması kirpilərin tarixi inkişafında yaşamaq uğrunda qazandığı uyğunlaşma əlamətidir. Qulaqlı kirpilərin daxili orqalarının indeksi göstərir ki, ürək və qaraciyərin nisbi kütləsi ilin fəsillərindən, heyvanın fizioloji vəziyyətindən, cinsindən və yaşından asılı olaraq dəyişir.

Yekun: Tədqiq olunan qulaqlı kirpilərin kranioloji göstəricilərində kəllənin kondilobazal uzunluğu, burun sümüyünün uzunluğu və alın sümüyü ölçülərində növdaxili populyasiya fərqinin olması müşahidə olunur. Belə ki, həm qulaqlı kirpilərin şimal populyasiyası nümayəndələrinin kəllə ölçüləri cənub populyasiya fərdlərindən aşağıdır. Qulaqlı kirpilərin daxili orqalarının indeksinin dəyişilmələri respublikamızın öyrənilən bölgələrinin hər birində özünəməxsus şəkildə müşahidə olunur. Bu zaman müşahidə olunan bölgələrarası fərq yüksək deyil.

Alzheimer’s disease is a brain neurodegenerative disorder, which is characterized with coordinative and cognitive dysfunctions with significant loss of memory. By the terms of Traditional Chinese Medicine (TCM) the Alzheimer’s disease may occur because of: spleen or liver Qi deficiency with phlegm, spleen and kidney yang deficiency, Qi and blood stagnations and others. With the use of Ginkgo biloba the stagnated energy, the excretion of the mucus and blocked blood can be mobilized and the blood circulation can be promoted to the brain. This study includes 5 patients, 4 women and 1 man, aged from 55 to 78. All patients have the disease for more than 2 years and main symptom in all is dementia. All patients have done certain number of acupuncture treatment and were prescribed Ginkgo biloba 1g per day. After starting the treatment all patients have stated that their health condition is improved, their memory is better and are feeling warmth and circulation to the head and neck. For a chronic and lifetime disease like Alzheimer’s, the treatment with Gingko Biloba is also for lifetime and it is shown to be successful in its aim to slow down the progression of the disease and release the symptoms.
