Published: December 2019

Introducción.  En la teoría de los tipos de personalidad vocacional y ambientes laborales de J. Holland, el modelo hexagonal organiza los datos personales y ocupacionales, y sirve para definir el grado de consistencia en la configuración de la personalidad y ambientes de trabajo, así como el grado de congruencia entre una persona y su ambiente. El objetivo del presente estudio fue analizar la validez estructural del modelo hexagonal de Holland y el jerárquico de Gati en una muestra de 636 estudiantes de bachillerato mexicanos, a través de las puntuaciones proporcionadas en la Búsqueda Autodirigida (SDS).Método.  Para analizar el ajuste de estos modelos se aplicó la prueba de aleatorización de relaciones de orden hipotetizadas (RTOR) y se llevaron a cabo escalamientos multidimensionales (EMD) no métricos.Resultados. El tipo de personalidad social presentó la puntuación media más alta, a continuación el tipo emprendedor y después el artístico y el investigador. Las puntuaciones medias más bajas correspondieron a los tipos realista y convencional. En relación con la consistencia interna se obtuvieron coeficientes alfa de Cronbach de aceptables (.765) a buenos (.845). Los resultados de la prueba RTOR indicaron un ajuste significativo moderado (IC=.65) del modelo de Holland y un ajuste alto (IC=.778) del modelo de Gati a los datos observados. La solución del EMD en la muestra total (Stress=.01; RSQ=.99) mostró que los tipos se distribuyen según el orden RIASEC, pero la disposición espacial entre ellos forma un círculo deforme porque el tipo investigador se sitúa hacia el centro del círculo. El análisis del ajuste según el sexo y curso escolar no indicó diferencias significativas (p>.05), aunque los estudiantes de tercero mostraron un nivel de ajuste más alto que los de primero y segundo de bachillerato.Discusión y conclusiones.  Los resultados aportan evidencia empírica de validez estructural de los modelos de Holland y Gati en la muestra de estudiantes. Estos modelos se pueden considerar una representación adecuada de los intereses vocacionales de estos estudiantes. Los resultados también aportan evidencia de validez de constructo de las puntuaciones del SDS, lo cual presenta implicaciones prácticas sobre la utilidad de este instrumento en la orientación vocacional y profesional.

Authors: Matosas-López Luis , Bernal-Bravo Cesar
Published: December 2019

Pocos son los estudios que analizan la presencia de las Tecnologías de la Información y la Comunicación (TIC) en los sistemas de valoración de la calidad docente. El presente trabajo revela el peso de las TIC en las etapas del diseño de un instrumento con episodios de comportamiento, destinado a evaluar la eficiencia del profesorado en modalidades online.La investigación, siguiendo la metodología Behavioral Anchored Rating Scales (BARS), implica en la construcción del mencionado instrumento a un total de 477 estudiantes y seis profesores de grados online de la Universidad Rey Juan Carlos.Los resultados revelan una elevada presencia de episodios de comportamiento con elementos TIC, tanto en las diferentes etapas del proceso de construcción como en el propio instrumento final. En este último, el 94.00% de los episodios de comportamiento recogen algún tipo de alusión a las TIC. Los hallazgos revelan que el Learning Management System (LMS), las video clases y la videoconferencia - con 63.83%, 34.04% y 29.79% respectivamente - son los recursos tecnológicos con mayor presencia en los episodios recogidos en el instrumento de medición resultante. Asimismo, los resultados muestran el peso específico de las TIC en las siguientes categorías de la docencia online: introducción de la asignatura, resolución de dudas, capacidad explicativa y facilidad de seguimiento.

Published: December 2019

Masa lansia merupakan suatu masa dimana kondisi fisik, kesehatan bahkan kognitif dari individu mulai mengalami penurunan. Dengan menurunnya kondisi kesehatan lansia, maka dibutuhkan perawatan kesehatan yang intensif dan cepat serta mudah untuk membantu lansia. Belakangan ini muncul banyak aplikasi kesehatan yang berfungsi sebagai pengingat maupun sebagai dokter online bagi lansia. Peranan ikon tentu sangat berpengaruh dalam pembuatan aplikasi kesehatan ini. Namun dalam penggunaannya, banyak ikon yang tidak efektif karena tidak dapat dimengerti maknanya secara cepat dan sukar untuk dikenali oleh penggunanya. Pengguna yang dalam hal ini adalah lansia terkadang mengalami kebingungan karena ikon tidak didesain secara baik sehingga menimbulkan kemiripan makna atau fungsinya. Berangkat dari permasalahan tersebut maka penelitian ini bertujuan untuk merancang ikon pada antarmuka aplikasi kesehatan untuk lansia. Subjek dari penelitian ini adalah lansia yang berumur 60 tahun ke atas.  Pembuatan ikon dilakukan dengan pendekatan metode User Centered Design dengan mewawancara responden untuk mendapatkan desain ikon yang paling nyaman digunakan.  Selanjutnya dilakukan pengujian terhadap desain ikon yang dibuat dengan melakukan performance test menggunakan dua buah parameter (completion rate dan task time). Hasil penelitian ini menunjukkan bahwa responden lebih memahami dan cepat mengenali fungsi suatu ikon ketika ikon didesain dengan jenis exemplar ikon, dengan bentuk 3 dimensi dan berwujud konkret yang dibuat dalam ukuran xhdpi dengan tingkat keberhasilan di atas 70%.

 

Abstract

Aging is a period when physical health and cognitive abilities begin to decline. Therefore, elderly need help in maintaining their physical health. Technology development has made it possible and more affordable for many people to manage their health using their smartphones. Currently, there are many mobile applications that can be used to help users take care of their heath, such as healthy lifestyle, and online doctor. However, not many elderly take advantage of these applications. Some of them undergo technological leap, and lack confidence in their shavvines. Therefore, it is necessary to design an application that is easy to use and less intimidating to the elderly. One way to do this is by designing icons that are easily understood by the elderly. This research studied different design approaches that are suitable for the elderly, using a user centered design approach. The study found that respondents could better understand icons that were designed using the exemplar approach, represented in concrete and 3D form, and has xhdpi size with success rate above 70%.

Published: December 2019

The poverty level of urban communities, indicated by the high rate of maternal and infant mortality, the presence of stunting problems, and the poor health of the elderly in the Cibereum Village, Cimahi City, have an impact on the lack of concern for individual health and environmental health. The Secercah Hati program is created with the purpose of overcoming such problems. This program is a community empowerment program to create a healthy, knowledgeable, and prosperous society by increasing the role of women. It  is collaborating with the Cimahi City Government Program, based on the 2017-2022 Cimahi City Medium Term Development Plan (RPJMD). Furthermore, the Secercah Hati Program is also an implementation of a partnership which is not only between Jenderal Achmad Yani University and the Cimahi City Government but also with Pasundan University. The program attempts to solve the issues by improving the role of Posyandu and Posbindu. The method of activity begins with a situation analysis that is coordinated with Cimahi City Government, problem identification, gathering and analyzing needs, determining priority problems, providing solutions, implementing, and evaluating. This participatory empowerment activity was carried out by forming a women's community consisting of Posyandu and Posbindu managers. Empowerment was implemented through training, workshops, mentoring, and role play (theatrical), so that they could optimize their role in improving public health and the environment and supporting the family economy. They were taught the ability to produce culinary with strong branding and market products utilizing digital marketing. In addition, they learnt to manage capital to support business sustainability. The program has an impact on increasing the number of cadres and the level of community participation in Posyandu and Posbindu activities, increasing the number of women entrepreneurs and increasing community income. The success of this community empowerment program needs to be supported by the concept of exciting and measurable activities in order to get a positive response from the community. Mentoring activities would be conducted continuously until the community is accustomed to and able to run programs independently and this is one of the keys to success. Implementing activities that synergize the Regional Government, Universities, and the community have proven to make the community empowerment program more effective.

La máquina como exoconciencia literaria en algunas obras de César Aira, Mario Levrero y Ricardo Piglia
Authors: Mora Vicente Luis
Published: December 2019

Desde los comienzos de la literatura, existe un profundo vínculo entre los seres humanos y los androides imaginarios. La presencia de este antiguo motivo en la literatura actual no debe entenderse como extraordinaria, desde el momento en que estas máquinas en los tiempos presentes están involucradas en discusiones científicas y filosóficas de ámbito mundial acerca de los límites éticos de la Inteligencia Artificial y la verdad efectiva de sus escalas de cognición y alerta. La principal idea de este artículo es que existe una buena base para suponer que nuestros fundamentos perceptivos y racionales son perfectamente reproducibles y desarrollables por las máquinas, no sólo desde el punto de vista de las teorías neurocientíficas que defienden la cognición expandida o distribuida, sino también en la imaginación de algunos escritores latinoamericanos como Mario Levrero, (La máquina de pensar en Gladys), César Aira (en varios libros, especialmente El pequeño monje budista) y Ricardo Piglia (La ciudad ausente). Estos autores parecen explorar la posibilidad de una exoconciencia ficticia.
Empathy and literary reading
Authors: Vinci Elisabetha
Published: December 2019

This contribution is aimed at analyzing  how empathy is instantiated when we read works of fiction and at studying which elements can improve the consonance between characters and readers. Starting from a brief summary about empathy with regard to literary texts, the paper examines the question concerning human reception of fictional characters in order to investigate how we empathize with them through the description of some elements which foster empathy: internal focalization, interior monologue and movement description. Fräulein Else by Arthur Schnitzler will serve as case study of empathic reading.
Tras la pista de Darwin. El problema de la fauna americana en las crónicas de José de Acosta y Gonzalo Fernández de Oviedo
Authors: Garí Barceló Bernat
Published: December 2019

El presente texto contiene una serie de pautas y consideraciones sobre la reflexión que el fósil y la fauna americana suscitaron en los primeros cronistas de Indias. No se trata tanto de un bosquejo descriptivo para visibilizar un asunto por lo general desatendido, como de una lectura interpretativa sobre los aportes y las claves que la crónica legó en el ámbito de la teoría de la tierra y de la vida. Las crónicas de Oviedo y Acosta se oponen en varios sentidos en la forma de conceptualizar esta problemática: la primera se resigna a prorrogar el modelo escolástico, no sin interrogar sus limitaciones, la segunda presagia formalmente el evolucionismo. Trataré de repensar dichos modelos a la luz de la revolución darwiniana.
Do Agricultural Raw Materials Imports Cause Agricultural Growth? Empirical Analysis from North Africa
Authors: Bakari Sayef
Published: December 2019

The aim of this paper is to study empirically the impact of agricultural raw materials imports on agricultural growth since it is never done before. We have made this study in the context of three Countries from North Africa (Tunisia, Morocco and Egypt) for the period 1965 – 2016. By using cointegration analysis and vector error correction model, empirical analysis proves that agricultural raw materials imports produce a positive effect on agricultural growth in the long run for the three Countries and cause agricultural growth in the short run in the case of Tunisia and Egypt. It is seen that agricultural raw materials imports is a source of economic growth in the agricultural sector. For this reason, countries of North Africa should adopt to integrate foreign technology imports and not technological innovation to stimulate agricultural sector.
VISÕES SOBRE ROGER BASTIDE

Published: December 2019

Nas tão vastas possibilidades de estudos sobre as religiões – cujos elementos de análise são, por sua vez, também múltiplos – há figuras de intelectuais que se destacam e perenizam depois que o conjunto de sua obra se torna conhecida e os resultados de suas pesquisas passam a constituir-se referências obrigatórias para a sucessiva progressão das investigações na(s) área(s) de sua atuação. Nessa perspectiva, estamos apresentando aos(às) leitores(as) da PARALELLUS - Revista de Estudos de Religião, do Programa de Pós-graduação em Ciências da Religião, da Universidade Católica de Pernambuco (PPGCR-UNICAP), no número 23, do volume 10 (2019), um dossiê sobre o sociólogo Roger Bastide, acadêmico francês que, durante quase duas décadas, atuou no Brasil, e aqui realizou pesquisas centradas na ampla cosmovisão das religiões de matriz afro-brasileira.
AYAHUASCA: UM SAGRADO SELVAGEM QUE BASTIDE NÃO CONHECEU
Authors: Silva Drance Elias , Braga João Paulo Reis
Published: December 2019

A Ayahuasca é uma bebida enteógena feita por meio da união de duas plantas: um cipó chamado Mariri (Banisteriopsis caapi) e as folhas de uma árvore chamada Chacrona (Psychotria viridis). O Chá Ayahuasca vem sendo usado há milhares de anos em rituais religiosos indígenas, e há algumas décadas em religiões urbanas como o Santo Daime e a União do Vegetal. A Ayahuasca é considerada uma bebida sagrada por todos que a utilizam regularmente em contexto religioso. Roger Bastide foi um teórico francês, que veio para o Brasil em 1938 e estudou durante muitos anos as religiões afro-brasileiras, dando enfoque a fenômenos como: a administração do sagrado, o sentimento de vergonha, e o processo de “domesticação” e persistência do “sagrado selvagem”. O presente artigo analisou também o conceito bastidiano de transe como “um jogo litúrgico”, que segundo ele, aproxima-se de uma “representação teatral”. As conclusões desse artigo sugerem que o transe provocado pela Ayahuasca transcende algumas das premissas bastidianas. Os resultados demonstraram ainda que as considerações que Bastide faz a respeito do processo de “domesticação do sagrado selvagem” podem ser observadas em religiões ayahuasqueiras como a União do Vegetal, ainda que em alguns pontos, a realidade da instituição não esteja em total consonância com as previsões feitas por Bastide.Palavras-chave: Ayahuasca. Bastide. Sagrado Selvagem. Transe Religioso. Enteógeno AYAHUASCA: A WILD SACRED WHICH BASTIDE DID NOT KNOWAbstractAyahuasca is an entheogenic drink made by the union of two plants: a vine called Mariri (Banisteriopsis caapi) and the leaves of a tree called Chacrona (Psychotria viridis). Ayahuasca tea has been used for thousands of years in indigenous religious rituals, and for decades in urban religions such as Santo Daime and União do Vegetal. Ayahuasca is considered a sacred drink by all who use it regularly in a religious context. Roger Bastide was a French theorist, who came to Brazil in 1938 and studied for many years the Afro-Brazilian religions, focusing on phenomena such as: the administration of the sacred, the feeling of shame, and the process of "domestication" and persistence of the "wild sacred". The present article also analyzed the Bastidian concept of trance as "a liturgical game", which he said, approaches a "theatrical representation". The conclusions of this article suggest that the trance provoked by Ayahuasca transcends some of the bastidian premises. The results also demonstrated that Bastide's considerations regarding the process of "domestication of the wild sacred" can be observed in ayahuasca religions like União do Vegetal, although in some points, the reality of the institution is not in total harmony with the predictions made by Bastide.Keywords: Ayahuasca; Roger Bastide; Wild Sacred; Religious Transe; Entheogen.

O VÉU DE MOISÉS E O SUDÁRIO DE JESUS (Ex 34,33-35; Jo 20,7)
Authors: Grenzer Matthias , Grenzer Francisca Antonia de Farias
Published: December 2019

Os autores neotestamentários, ao contemplarem o mistério presente na pessoa de Jesus, usam as imagens pertencentes à literatura veterotestamentária; estas, em geral, estão carregadas de conotações teológicas. Possivelmente, isso vale também para o sudário que estava sobre a cabeça de Jesus. Mencionado somente em Jo 20,7, o sudário talvez possa ser compreendido a partir do véu que estava sobre a face de Moisés: peça têxtil três vezes mencionada em Ex 34,33-35. O estudo aqui apresentado visa investigar tal paralelismo, o qual é pouco valorizado nos Comentários sobre o Evangelho segundo João publicados em língua portuguesa. Além disso, por mais que seja investigado um paralelismo já visto por outros, comumente surgem novos detalhes e novas compreensões ao se procurar de novo pelo sentido do texto.Palavras-chave: Véu, sudário, Moisés, Jesus. AbstractThe New Testament authors, in contemplating the mystery present in the person of Jesus, use the images belonging to the Old Testament literature, which are, in general, loaded with theological connotations. Possibly, this also applies to the shroud that was on Jesus’ head. Mentioned only in John 20:7, the shroud may perhaps have understood from the veil that was on the face of Moses, textile piece three times mentioned in Ex 34:33-35. The study presented here proposes to investigate such parallelism, which is little valued in the Commentaries on the Gospel according to John, published in Portuguese language. Moreover, however a parallelism already has been investigated by others, new details and new understandings often emerge when one looks again for the meaning of the text.Keywords: Veil, shroud, Moses, Jesus.

A Case of Widespread Cutaneous Metastases from Esophageal Adenocarcinoma
Authors: Crain Caroline Brooke , Nguyen Adam , Wilson Janice , Wilkerson Michael
Published: December 2019

Cutaneous metastases from internal malignancies are very rare, and only a few cases from esophageal cancer have been reported. We describe the case of a 61-year-old patient with recently diagnosed esophageal adenocarcinoma who presented with multiple skin nodules. Immunohistochemical analysis of the nodules matched the immunohistochemical profile of the patient’s previous esophageal biopsy specimen confirming the diagnosis of cutaneous metastases. This case highlights the importance of including cutaneous metastases in the differential diagnosis of any suspicious lesion in patients with a history of internal malignancy.
Adjunct Treatment of Recalcitrant Hand Plaques in Nephrogenic Systemic Fibrosis After Imatinib Therapy
Authors: Foshee James , Griffin Thomas , Cam Kristin , Rivlin Michael , Keller Matthew
Published: December 2019

Nephrogenic systemic fibrosis (NSF) is a sclerotic disorder presenting with painful indurated plaques and skin thickening involving the trunk and extremities, which can lead to tethering and joint contractures.  NSF most commonly affects patients with renal insufficiency who have been exposed to gadolinium. We present a case of NSF involving the bilateral hands, knees, and lower extremities developing over 10 years after gadolinium exposure.  Initial improvement was noted in the lower extremities after initiation of imatinib mesylate therapy, but recalcitrant, thickened hand plaques caused persistent pain and functional limitation. Adjunct intralesional corticosteroid injections produced durable softening of the recalcitrant lesions with considerable functional improvement in hand mobility. Based on our experience, intralesional corticosteroid injections appear to be an effective adjunct treatment in patients with incomplete response to anti-fibrotic therapies.
Optimizing Medical Student Dermatology Education with the American Academy of Dermatology’s Basic Dermatology Curriculum
Authors: Regan Paul A , Sciacca Kirby Joslyn
Published: December 2019

Skin disorders are among the most common complaints in primary care settings, yet dermatology is often underrepresented in medical school curricula. Lecture time during the preclinical years is limited, and clinical dermatology rotations are rarely mandatory. Therefore, dermatology learning during medical school must be efficient and effective. The American Academy of Dermatology’s Basic Dermatology Curriculum is a set of peer-reviewed, online learning modules that serve as an introductory educational resource for medical students to learn about skin disease. Several studies have demonstrated positive effects of the modules in dermatology instruction, and the use of the modules in medical school curricula has been strongly supported by students. Dermatology educators should consider incorporating the Basic Dermatology Curriculum modules into preclinical and clinical medical student dermatology education.
Adult-Onset Still’s Disease Presenting as an Atypical Cutaneous Eruption
Authors: Kosche Cory , Zheng Lida , Guggina Lauren
Published: December 2019

Adult-onset Still’s disease classically presents with high fevers, arthralgias, leukocytosis, and an evanescent eruption. There are, however, a known subset of patients who develop an atypical eruption with persistent erythematous to violaceous papules and plaques. Here, we present the case of a white female in her 40s who presented with 2 years of spiking fevers, arthralgias, and a fixed pruritic eruption with erythematous plaques with overlying scale and linear accentuation. She was initially treated with oral prednisone, anakinra, and methotrexate. Due to persistent symptoms, she was switched to adalimumab with significant relief of symptoms. Prompt recognition of adult-onset Still’s disease with this atypical eruption may help prevent delayed or missed diagnosis and allow for early, appropriate intervention.
Transitioning Between Biologics
Authors: Vender MD FRCPC Ronald
Published: December 2019

Background: Transitioning between biologics has become an important part of practice.Objective: Patients with moderate to severe plaque psoriasis who are on biologics can have efficacy failures, as well as safety concerns. This would often necessitate a change of biologic, which may be within the same class or to a different class. A change due to an adverse event from the presently used biologic may resolve or require treatment until a new biologic is introduced, which may pose some delay in the initiation of the subsequent biologic. Methods: A review of the literature and guidelines published were performed. Results: A practical guide to transitioning between biologics are presentedLimitations: There are no randomized placebo-controlled trials to determine the best method of transitioning between biologics.Conclusion: Transitioning between biologics is an option for those patients requiring such a change either for safety or efficacy reasons.

Quantum Lenoir Engine with a Single Particle System in a One Dimensional Infinite Potential Well
Authors: Saputra Yohanes Dwi
Published: December 2019

Lenoir engine based on the quantum system has been studied theoretically to increase the thermal efficiency of the ideal gas. The quantum system used is a single particle (as a working fluid instead of gas in a piston tube) in a one-dimensional infinite potential well with a wall that is free to move. The analogy of the appropriate variables between classical and quantum systems makes the three processes for the classical Lenoir engine applicable to the quantum system. The thermal efficiency of the quantum Lenoir engine is found to have the same formulation as the classical one. The higher heat capacity ratio in the quantum system increases the thermal efficiency of the quantum Lenoir engine by 56.29% over the classical version at the same compression ratio of 4.41.

Authors: Wahyuni Nelly , Rudiyansyah Rudiyansyah , Safitri Mellisa N.
Published: December 2019

Waste glass materials coming from municipal and industrial processes have become a serious problem for the environment in the near future. Silica gels have been long attracting attention since it is widely used for many applications. It had also been studied by several fields because of its surface properties. In this study, semi-polar silica gels have been synthesized. C4-silica gels have been prepared by reaction between tributylamine (TBA) and silica gels produced from waste glass. The waste glass was powdered, soaked in NaOH, then heated at 400 oC to obtain sodium silicate. Silica gels were produced by neutralized the sodium silicate using HCl, dissolved in H2O, and dried in an oven at 80 oC. Silica gels were solubilized in TBA, stirred, and dried in the oven to obtain C4-silica gels. Silica gels were characterized by X-ray Diffraction (XRD), while Infra Red (IR) and Scanning Electron Microscopy (SEM) analyses were conducted to obtained C4-silica gels. XRD analysis of silica gels showed that the highest peak intensity was observed at 2θ = 22.655°. The band at 1381.03 cm-1 in the IR spectrum was attributed to the nitro-oxygen bond (N-O). SEM images showed that the surface of C4-silica gels was smoother and more flat than the previous silica gels.

Published: December 2019

The sulfolipid sulfoquinovosyl diacylglycerol (SQDG) and its headgroup, the sulfosugar sulfoquinovose (SQ), are estimated to harbour up to half of all organosulfur in the biosphere. SQ is liberated from SQDG and related glycosides by the action of sulfoquinovosidases (SQases). We report a 10-step synthesis of SQDG that we apply to the preparation of saturated and unsaturated lipoforms. We also report an expeditious synthesis of SQ and (13C6)SQ, and X-ray crystal structures of sodium and potassium salts of SQ. Finally, we report the synthesis of a fluorogenic SQase substrate, methylumbelliferyl a-D-sulfoquinovoside, and examination of its cleavage kinetics by two recombinant SQases.

Published: December 2019

Simultaneous activation of carboxylates and phosphates provides multiple pathways for the generation of reactive intermediates, including mixed carboxylic acid-phosphoric acid anhydrides, for the synthesis of peptidyl-RNAs, peptides, RNA oligomers and primordial phospholipids. These results indicate that unified prebiotic activation chemistry could have enabled the joining of building blocks in aqueous solution from a common pool and enabled the progression of a system towards higher complexity foreshadowing the modern encapsulated peptide-nucleic acid system
Tutor facilitation in a PBL writing classroom through face-to-face group interactions
Authors: Aliyu Muhammad Mukhtar , Yong Mei Fung
Published: December 2019

Proficiency in writing in English has been a very important skill for undergraduates especially English as second language learners (ESL). However, it is the most challenging language skill to be acquired by the students not only in second (L2) or foreign language (FL) but also in the first language (L1). This is due to its complexity. Some scholars describe writing as a cognitive and social process. Various studies have been conducted on how to improve students’ writing skills. It is shown that supporting students in a writing process enhances their writing skills. For example, teachers are expected to give cognitive and social supports to students to allow them to improve their writing. This study reveals the strategies used by tutors in facilitating students’ writing process in a problem-based learning environment (PBL) through face-to-face group interactions. is one of the social media platforms found interesting and used by most of the students to interact with one another in and out of the school environment. It is used to provide social support to the students. An intact class of 18 second-year students in an English Composition course in Nigeria was selected in the study. The students were provided with a guide by tutors during the PBL writing process. Two tutors facilitated the students’ writing process in the PBL process. Tutor facilitation is one of the major components that facilitate meaningful learning in PBL. This is because, without proper guidance, students would end up in unfocused learning. Data were obtained through audio- and video-recording of students’ face-to-face interactions chats. The findings showed that the PBL tutors used various strategies to facilitate the participants’ writing such as open-ended questioning, metacognitive questioning, pushing students for an explanation, revoicing, summarizing, and generating/evaluating hypotheses. The support provided by the tutors helped the students to improve their writing. The findings of the study suggest some ways for teachers to improve students writing skills.

CX3CR1, one of the highest expressed genes in microglia in mice and humans, is implicated in numerous microglial functions. However, the molecular mechanisms underlying Cx3cr1 signaling are not well understood. Here, we analyzed transcriptomes of Cx3cr1-deficient microglia under varying conditions by RNA-sequencing (RNA-seq). In 2-mo-old mice, Cx3cr1 deletion resulted in the down-regulation of a subset of immune-related genes, without substantial epigenetic changes in markers of active chromatin. Surprisingly, Cx3cr1-deficient microglia from young mice exhibited a transcriptome consistent with that of aged Cx3cr1-sufficient animals, suggesting a premature aging transcriptomic signature. Immunohistochemical analysis of microglia in young and aged mice revealed that loss of Cx3cr1 modulates microglial morphology in a comparable fashion. Our results suggest that CX3CR1 may regulate microglial function in part by modulating the expression levels of a subset of inflammatory genes during chronological aging, making Cx3cr1-deficient mice useful for studying aged microglia.

Through the progressive accumulation of genetic and epigenetic alterations in cellular physiology, non–small-cell lung cancer (NSCLC) evolves in distinct steps involving mutually exclusive oncogenic mutations in K-Ras or EGFR along with inactivating mutations in the p53 tumor suppressor. Herein, we show two independent in vivo lung cancer models in which CHUK/IKK-α acts as a major NSCLC tumor suppressor. In a novel transgenic mouse strain, wherein IKKα ablation is induced by tamoxifen (Tmx) solely in alveolar type II (AT-II) lung epithelial cells, IKKα loss increases the number and size of lung adenomas in response to the chemical carcinogen urethane, whereas IKK-β instead acts as a tumor promoter in this same context. IKKα knockdown in three independent human NSCLC lines (independent of K-Ras or p53 status) enhances their growth as tumor xenografts in immune-compromised mice. Bioinformatics analysis of whole transcriptome profiling followed by quantitative protein and targeted gene expression validation experiments reveals that IKKα loss can result in the up-regulation of activated HIF-1-α protein to enhance NSCLC tumor growth under hypoxic conditions in vivo.

Improving learning vector quantization using data reduction
Authors: Semadi Pande Nyoman Ariyuda , Pulungan Reza
Published: December 2019

Learning Vector Quantization (LVQ) is a supervised learning algorithm commonly used for statistical classification and pattern recognition. The competitive layer in LVQ studies the input vectors and classifies them into the correct classes. The amount of data involved in the learning process can be reduced by using data reduction methods. In this paper, we propose a data reduction method that uses geometrical proximity of the data. The basic idea is to drop sets of data that have many similarities and keep one representation for each set. By certain adjustments, the data reduction methods can decrease the amount of data involved in the learning process while still maintain the existing accuracy. The amount of data involved in the learning process can be reduced down to 33.22% for the abalone dataset and 55.02% for the bank marketing dataset, respectively.

Survei Batimetri dan Arus dilakukan untuk  mengetahui peta batimetri dan pola arus disekitar pelabuhan Jampea. Hasil penelitian ini diharapkan dapat memberikan gambaran hasil pengujian di lapangan dengan hasil uji numerik pada data yang akan diolah.  Penelitian dilaksanakan pada bulan Juni hingga bulan Agustus 2019 di perairan pelabuhan Jampea Kabupaten Selayar. Metode yang digunakan adalah kuantitatif. Pengambilan data pemeruman  dengan Echosounder  Singlebeam Garmin  GPS MAP 178C.  Sedangkan pengukuran arus dilaksanakan 2 kali, yaitu pada saat pasang tertinggi (spring tide) dan terendah (neap tide).  Penyajian  data  ditampilkan  dengan software SMS 10.0 (Surface water modeling system).  Dari hasil pengukuran dilapangan bahwa arus menjelang pasang memiliki kecepatan rata-rata adalah 0,044 m/s, pada saat pasang inilah arus laut mengarah ke arah tenggara. Sementara itu, pada saat menjelang surut, kecepatan arus rerata adalah 0,08 m/s dan mengarah ke barat laut. Sedangkan pada hasil analisa software SMS.10 dimana pada saat surut, arus di sekitar lokasi studi dominan bergerak dari tenggara ke barat laut dengan kecepatan rerata 0,009 m/detik dan pada saat pasang di sekitar daerah studi arus bergerak dari barat laut menuju ke tenggara dengan kecepatan  rerata yaitu  0,0084 m/detik.  Kondisi batimetri pada areal sekitar pelabuhan Jampea termasuk kategori pantai yang landai dimana pesisir atau tepi laut yang daratannya menurun sedikit demi sedikit ke arah laut yang mengakibatkan pengaruh pasang surut sangat jauh keluar menuju ke laut.
Modeling and Simulation of the Photovoltaic Cells for Different Values of Physical and Environmental Parameters
Authors: Hysa Azem
Published: December 2019

Both research and technological development in the area of renewable energy sources are necessary to account for the increase in energy demand and environment problems in the world. The photovoltaic (PV) cell has been described by non-linear outputs characteristics in current-voltage and power-voltage. This outputs is affected by various effects such as; series resistance ( ), shunt resistance ( ), solar irradiance and temperature. In this paper the effect of variation of parameters has been studied such as series resistance ( ) and shunt resistance ( ) of the diode in the photovoltaic cell and these effects could be seen in the Current-Voltage (I-V) and Power-Voltage (P-V) characteristic curves. In this paper also has been studied the effect of variation of the environmental parameters such as solar irradiance and temperature. Results show that a higher temperature at constant solar irradiance produces a decrease power. So the voltage and the photovoltaic cell output power tend to decrease at higher temperatures, but there is no noticeable effect on the photovoltaic cell current. Thus, it is important to keep the cell temperature as low as possible, because higher temperatures have negative effect on output power of photovoltaic cell. On the other hand, the effect of solar irradiance on photovoltaic cell, it reveals that higher solar irradiance gives higher current and higher power. Shunt resistance has significant effect on the operating characteristic curves of PV cells as low power output is recorded if the value of shunt resistance varies from 0.07 ohms to 1700 ohms. Finally, I have presented power-voltage characteristic curves and current voltage characteristic curves of photovoltaic cell for different solar irradiance in Shkoder, Tirana and Vlore.

Published: December 2019

Ecuador es el primer exportador de banano del mundo con más de 317 millones de cajas por año, lo que aporta el 26 % del PIB agrícola y genera alrededor de 2.5 millones de empleos directos e indirectos. Ecuador produce 19 000 ha y exporta 36 000 t de banano orgánico. Respecto a las pérdidas poscosecha, estas fluctúan entre el 10 y 80 % y son causadas por un inadecuado manejo tanto de la poscosecha como en lo agronómico. Este estudio tiene el objetivo de determinar la calidad física y química de la fruta orgánica y cuantificar las pérdidas poscosecha. La investigación se llevó a cabo en una plantación de banano orgánico ubicada en la provincia de Los Ríos (Ecuador). Se utilizó un diseño de bloques completamente al azar (DBCA) en arreglo factorial 7 x 2. Los factores fueron las épocas de cosecha (febrero-agosto), y la calidad de la fruta de exportación (primera y segunda) con 3 repeticiones. Las variables estudiadas se determinaron con base en 20 racimos. De los resultados obtenidos, se deduce que la calidad física y química del fruto está influenciada por la época de cosecha, ya que los racimos crecieron y desarrollaron en diferentes condiciones ambientales. En general, el 82 % de la producción se destina para la exportación, debido a que cumple los estándares de calidad.
