New perspectives of biological therapy for severe asthma in adults and adolescents
Authors: Chheang Chenda , Guinand Stéphane , Von Garnier Christophe , Sartori Claudio
Published: May 2022

Severe asthma is associated with increased morbidity, mortality, healthcare costs and impaired quality of life. Asthma is no longer considered as a single entity but as a heterogeneous disease with different clinical presentations (phenotypes) and variable underlying mechanistic biological pathways (endotypes). Two different endotypes are based on the inflammatory Type 2 T-helper response: T2-high and T2-low. The understanding of these endotypes has revolutionised the management of severe asthma. Recent guidelines from the 2019 European Respiratory Society/American Thoracic Society (ERS/ATS) and Global Initiative for Asthma (GINA) 2021 specifically address the diagnosis and the management of severe asthma in adults, but less evidence exists for the paediatric population. Presently, five biologics for the treatment of severe asthma are approved, i.e., omalizumab (anti-IgE antibody), mepolizumab and reslizumab (anti-IL-5 antibody), benralizumab (anti-IL-5 receptor antibody) and dupilumab (anti-IL-4 receptor alpha antibody). This article reviews the pathological mechanisms of severe asthma, clinical biomarkers related to the T2-high endotype, and their use for the prediction of the severity of the disease and response to biological therapy. Furthermore, future developments of biologics for severe asthma are presented.

Trong nghiên cứu này, chúng tôi đã tổng hợp thành công Nano Đồng (CuNP) bằng cách sử dụng quercetin làm chất khử xanh. Các điều kiện tối ưu để tổng hợp các hạt CuNP như nồng độ đồng sunfat (CuSO4), polyetylen glycol (PEG-6000), nhiệt độ phản ứng, tỷ lệ chất khử / dung dịch, pH và thời gian phản ứng đã được khảo sát và tương ứng là 1-3 mM, 2%, 60 ˚C, 10 mL / 100 mL, 8 và 30 phút. Khi quan sát quá trình phản ứng, sự thay đổi màu sắc từ màu xanh lam của dung dịch sang màu nâu nhạt thông qua quan sát  bằng mắt có thể dự đoán sự hình thành các hạt CuNP. PEG-6000 được sử dụng làm chất phân tán các hạt CuNP trong hệ keo. Các hạt CuNP thu được sau đó được xác định các đặc trưng cấu trúc bởi các phương pháp phân tích  hóa lý như UV-Vis, tán xạ ánh sáng động (DLS), nhiễu xạ tia X (XRD), phổ hồng ngoại biến đổi Fourier (FT-IR) và kính hiển vi điện tử truyền qua (TEM). Bằng cách sử dụng XRD cho thấy đặc trưng cấu trúc của CuNPs sở hữu cấu trúc mạng tinh thể lập phương tâm diện (FCC) trong tự nhiên. Kết quả đo TEM cho thấy sự hình thành các hạt CuNP có kích thước trung bình khoảng 15-30 nm.

Authors: Nasir M. , Samwil Samwil , Subhi Muhibbul
Published: May 2022

Al-Qur'an is the word of Allah SWT which contains various kinds of rules, guidelines for human life that governs every aspect of life, including the child's personality. One of the surahs that talk about children is Surah Al-A'raf verses 31-33, In that verse, Allah SWT gives an illustration to believers about how to dress, drink, and do evil deeds. Concerning this verse, Ash-Shawi provides an in-depth understanding of how to dress, eat and drink permitted by the Law. This discussion aims to find out the interpretation of Surah Al-A'raf verses 31-33 in the Ash-Shawi's interpretation related to personality and to figure out the educational values emphasized in the verse. The writer uses a literature study as a data collection technique. The child's personality is determined by Islamic education in the family. This is obtained by nurturing and guiding because the children were born in a state of nature that requires guidance and direction to develop their potential.

Published: May 2022

Many educators still use conventional teaching materials, namely teaching materials that are ready to use, just buy, instant, without the effort of planning, preparing, and compiling their own and less attracting children's attention in learning. So the image media is used as a development effort in learning Indonesian. This study aims to determine the quality of teaching materials based on the validation of material experts and media experts, to determine the attractiveness of teaching materials based on student responses, and to determine the average increase in student achievement based on pretest and posttest scores. This research was carried out at SDN 101938 Adolina, Perbaungan District, for the 2021-2022 academic year. This research is development research. The subjects of the study were the fifth grade students of SDN 101938 Adolina, Perbaungan District, for the academic year 2021-2022 with a total of 36 students. Data collection techniques used are tests, questionnaires, and documentation. The data analysis technique used is the percentage and the average. The results of the overall quality of teaching materials are good with a percentage of 78%. The results of the attractiveness of teaching materials based on student responses in the limited trial obtained a percentage of 87% with a very interesting category, while in the large group trial a percentage of 85% was obtained with a very attractive category. The average value of the pretest is 6.09, while the average value of the posttest is 8.44, so it can be concluded that there is an increase in the average student achievement.

Sobre la adscripción lingüística del Ribagorzano.
Authors: Sanz Casasnovas Gabriel
Published: May 2022

Desde que los filólogos comenzaron a describir y clasificar las distintas lenguas románicas, algunas áreas dialectales han quedado difuminadas y reducidas a la categoría de zonas de transición. El presente artículo analiza tres rasgos lingüísticos del ribagorzano situándolos en un tiempo y espacio concretos: el comitatus Ripacorcensis de los siglos X y XI. El estudio de la lengua viva, la scripta condal y la toponimia desde una perspectiva panrománica demuestra que dichos rasgos emergieron en Ribagorza de manera autónoma, y refuerza la consideración del ribagorzano como romance independiente.
Generation Y – Between Challenges of the Knowledge Society and Demands of a Prosperous Market
Authors: Felger Branimir
Published: May 2022

This paper deals with elements from which modern society has created a particular gap into which it has pushed young generations, named by scientists, the media and the public, Generation Y. This gap appears between the society of knowledge, in all its conceptual poverty and absurdity on the one hand, and demands of prosperous markets, on the other. The first part of this paper will present the definition and main characteristics of millennials, as well as the socio-historical context of their development. This is followed by an analysis of the media that reproduce and, to a large extent, determine the conditions and environment in which these generations exist. They are subject to technological socialization, which means they do not come into contact with each other but with machines. In this way they achieve only contact, instead of actual human relationships as experienced by previous generations. This paper also deals with technologies commonly known as “new”, although, as we write these lines, some of them have probably already become outdated and are being replaced by newer ones. This is how fast the world changes.
Zamaskirani jezik mržnje
Authors: Terzić Dario
Published: May 2022

Jezik sam po sebi nije savršeno sredstvo komunikacije, pa često značenje koje riječima pridaje onaj tko ih je izgovorio ili napisao nije istovjetno s mnoštvom značenja koja riječima daju oni koji ih slušaju ili čitaju. Riječima nije teško manipulirati.Govor mržnje obuhvaća izjave koje zastrašuju, uznemiravaju pojedince i grupe ali i izjave koje pozivaju na nasilje, mržnju te na diskriminaciju pojedinca ili grupa. Razlozi za mržnju i diskriminaciju su uglavnom: rasa, vjera, spol ili seksualna orijentacija.Govor mržnje postaje još kompleksniji ako se zna da on uopće i ne mora počivati na lažima i uvredama. Na pomolu je estetizacija mržnje, maskiranje jezika mržnje kroz provokativne, intrigantne pa nerijetko i zapaljive sadržaje. Kako bi privukli pažnju, novinari upotrebljavaju i naslove koji danas, u eri online medija mogu izazvati vrlo zlonamjerne komentare na forumima, pa tako stvoriti negativno i neprijateljsko ozračje.
S one strane znanosti: koronavirus kao društvena činjenica i problem moderne
Authors: Šuran Fulvio
Published: May 2022

Značajna nemoć znanosti i protuslovlja pokrenuta od strane koronavirusa dovela je svijet do krize koja u svojoj sveopćosti ujedinjuje i otkriva nejednakosti predlažući novo razmatranje ideje modernosti i uloge društvenih znanosti. Zapravo, raznovrsne su sociološke točke pristupa epidemiji. Kao na primjer: prekid rituala koji definiraju redoslijed socijalne interakcije zbog prakse distanciranja; širenje osjećaja kolektivnog straha (moral panics) posredstvom medija i institucija koji svoj razlog ima u potrebi kolektivnog prihvaćanja velike požrtvovnosti na individualnoj razini u vezi odnosa troškova/koristi; struktura i gustoći društvenih mreža kao prediktoru širenja zaraze. Izlaganje nudi samo neka kritična osvrtanja utemeljena na dijalektici da bi pravovaljano odgovorilo na situaciju neprekidne napetosti između načela jedinstva i podjela oko kojih se društveni svijet, zbog svoje fluidnosti neprestano preuređuje. Zasnivajući se dakle na logici društvenog poretka koja podrazumijeva da se svaka tematika, događaj ili situacija može razumjeti kao privremena točka ravnoteže između kohezivne i disperzivne društvene dinamike.

El objetivo de este estudio es proponer acciones  para facilitar la cooperación entre la Universidad – Empresa en el sector agroalimentario de la Región de Coquimbo Chile, de manera de potenciar la generación de procesos de vinculación con el entorno y algunos aspectos internos y externos a los entes involucrados que afectan dichos procesos. Para esto se realizaron entrevistas semiestructuradas  in situ en: oficinas, predios, a representantes de los ámbitos: académicos, empresarial y de gobierno de las tres provincias que componen la región. Se identificó que la mayoría de vínculos entre universidad y entorno nacen como consecuencia de las relaciones interpersonales de los líderes o los miembros de los grupos, las cuales posteriormente servirían  para formalizar la vinculación mediante convenios o contratos. Asimismo, se hace evidente que las potenciales capacidades de las universidades son un factor clave, sin embargo estas deben ser orientadas a la solución de problemas y aprovechamiento de oportunidades del sector agroalimentario.
Photography as a Form of Technological Mediumship in the 19th Century Spiritualism
Authors: BAYÜLGEN Burak , HEPDİNCLER Tolga
Published: May 2022

The 19th century has been a shift in sight, observation and perception. It has been a change from the rational way of seeing to the subjective and physiological way of seeing, perception and expression. This century has been also a process for spiritualists who used their physiological bodies to communicate with spirits. Different disciplines and professions have been formed with the invention of photography. For this very reason, spiritualists have combined photography with physiology, and used technology as “mediums” to prove the visibility of spirits. Nevertheless, the 19th century has been also the exploitability of different disciplines and means of productions as much as their benefits. Spiritualists and spirit photographers have been denounced as impostors. However, spirit photography has endeavored to prove that a reality existed beyond the visible, and the visibility of spirits endorsed the spiritual narratives by invigorating the ties between technology, photography and observation. This article will document the arguments of the spiritualists, defenders and debunkers of the 19th century and portray their contribution to observation and subjectivity (mediumship) as much as spiritualism.

The Compilation Records of Fireflies (Coleoptera: Lampyridae) Diversity and Distribution and Display Trees Throughout Malaysia
Authors: Abu Seri Nurhafizul , Abd Rahman Azimah
Published: May 2022

The populations of fireflies (Coleoptera: Lampyridae) are increasingly being threatened, and it is, thus, a significant problem in Southeast Asia, particularly Malaysia. Fireflies and their habitat must immediately be protected before they go extinct. Simpson’s Diversity Index used in this paper review to measure the diversity of firefly species across Malaysia. The Simpson’s Diversity Index showed that the richness and evenness of firefly species in Malaysia is infinite diversity with D = 0.2255. The authors compiled and reviewed the studies on the firefly species to incorporate available information/data and emphasised their preferred habitat/display trees in response to the issue. Therefore, this paper was also able to track down records of fireflies’ species’ distribution through the previous studies in eight states in West Malaysia (Peninsula), namely Johor, Kelantan, Kuala Lumpur, Pahang, Perak, Negeri Sembilan, Selangor, and Terengganu, as well as two states in East Malaysia (Borneo), namely Sabah and Sarawak. It indicates that firefly species, especially from the general Pteroptyx (Pteroptyx tener species), are widely distributed in Peninsular Malaysia and East Malaysia. Based on the records from the study conducted by previous researchers, it was found that the population of fireflies is declining in some areas in Malaysia, and so are their habitats and host/display trees that have suffered the same decline. Perhaps, this paper will help broaden human beings’ geographical understanding/knowledge and create awareness which eventually leads to conservation actions of firefly species and their host/display trees.

Published: May 2022

This case report describes a 49-year-old immunocompromised woman with tenosynovitis of the left middle finger caused by Group B Streptococcus (GBS). She claimed that a fishbone picked over her left middle finger. An orthopaedic surgeon operated for incision and drainage of pus discharge, wound debridement of the left middle finger and A1 and A2 pulley release. Treatment was initiated with parenteral cefepime three times per day given the growth of mixed Enterobacter species on the culture media and continued with oral cefuroxime twice daily upon discharge for one week. Unfortunately, during the orthopaedic clinic follow-up, the wound was unclean with a slough and skin necrotic patch. Therefore, Ray’s amputation of the left middle finger proceeded. This case contributes to further investigation of the GBS tenosynovitis due to the rise in GBS invasive infections and shows the importance of early diagnosing and initiating treatment with antibiotics that are effective against this pathogen.

Published: May 2022

Bio-based polymer is a promising candidate to substitute conventional petroleum-derived polymer as it is sustainably produced from renewable resources, which helps reduce the production process’ carbon footprint. It also helps reduces humankind’s dependability on fossil fuel-based feedstock. In this work, a sustainable jatropha oil-based polyurethane acrylate (PUA) was successfully prepared and synthesised using a 3-steps process; epoxidation (formation of an epoxy group), hydroxylation (addition of–OH group to opened ring), and acrylation (addition of acrylate group into polyol). The yellowish PUA prepared has a gel consistency, which is sticky and slightly runny. The PUA was characterised by using wet chemical tests such as oxirane oxygen content (OOC), acid value (AV), hydroxyl number (OHV) and iodine value. OOC value for the PUA synthesised was 4.23 % at the 5 hr reaction time. At the same time, the Epoxidised jatropha oil (EJO) used to prepare polyol records a hydroxyl number of hydroxyl 185.81 mg KOH/g and an acid value of 1.06. The polyol prepared was mixed with 2, 4-toluene-diisocyanate (TDI) and Hydroetyhlmethacrylate (HEMA) to produce PUA. The PUA was characterised by thermogravimetry analysis (TGA) and electrochemical impedance spectroscopy (EIS). TGA analysis shows that the polymer is stable up to 373 K, whereas the EIS analysis records an ionic conductivity of (5.60±0.03) × 10-6 S cm-1. This polymer’s great thermal stability properties make it suitable for outdoor application where high temperature due to sun exposure is common. Furthermore, PUA prepared gel-like properties to make it a suitable candidate for preparing a gel polymer electrolyte.
A Review on Soil Erodibility Studies in Malaysia
Authors: Derahman Adnan , Bachok Mohd Fairuz , Shukor Muhamad Fuad , Mohd Latib Farah Wahida , Alias Rohaya
Published: May 2022

Studies on soil erodibility in Malaysia were critically reviewed. Soil erodibility is the only factor of Universal Soil Loss Equation (USLE), which requires laboratory work and analysis complexity to estimate soil loss. Therefore, the main objective is to review soil erodibility studies to enhance understanding of Malaysia’s soil erosion impacts. These studies were summarized in their application, purpose, value, utilization method/approach, and study location. On the other hand, a summarization of what, why, where, and how the soil erodibility was used was analyzed. Therefore, the importance of soil erodibility as input for environmental management and conservation practices can be addressed. For a large-scale area, the soil erodibility factor will be analyzed as one of the USLE variables in estimating the erosion rate. As for a small-scale area, this factor is an adaption of the ROM Scale, which use to identify the slopes or riverbanks prone to landslides induced by erosion. However, the determination of this factor requires extensive artistry, time, and cost. These would be an obstacle to the holistic assessment of soil erosion impacts since only a little soil sampling will be analyzed. Therefore, the simplified version for the determination of soil erodibility without any requirement of laboratory works will be an extra mile, especially for an area that does not have any information on soil series.
Methods for Multiple Attribute Group Decision Making Based on Picture Fuzzy Dombi Hamy Mean Operator
Authors: Saad Muhammad , Rafiq Ayesha , Perez-Dominguez Luis
Published: May 2022

In this work, ambiguity and unclarity are coped with the effective tools of picture fuzzy sets (PFSs), especially where the conditions demand simulation of various dimensions for evaluation, for example, decision making. PFS requires operators to measure the coordination of two PFSs. As far as this paper is concerned, we bring new operators to PFSs with an application, validating this as the generalization of the concept of Fuzzy Sets (FSs) and Intuitionistic Fuzzy Sets (IFSs). The hybrid structure of PFSs has been incorporated with other operators to develop picture fuzzy Dombi Hamy mean (PFDHM) operator, picture fuzzy weighted Dombi Hamy mean (PFWDHM) operator, picture fuzzy Dombi dual Hamy mean (PFDDHM) operator, and PF weighted Dombi dual Hamy mean (PFWDDHM) operator. Further, the properties such as Idempotency, Monotonicity, Boundedness, and Commutativity related to each proposed operator have been discussed. By using these operators the multiple attribute group decision-making (MAGDM) methods are proposed. Moreover, we have explained the application by providing an example of a car supplier. The results are concluded by selecting the best car on the basis of attributes such as quality, production, service efficiency, and risk factors using operators defined on PFSs. A comparative study is also conducted to study the significance of the developed work.

The Direct Cost of Autism and its Economic Impact on the Filipino Family
Authors: Quilendrino Maria Isabel O. , Castor Mary Anne R. , Mendoza Nenacia Ranali Nirena P. , Vea Jacqueline R. , Castillo-Carandang Niña T.
Published: May 2022

Background. The increasing prevalence of autism has significantly impacted the health care spending of many families worldwide. To date, families from low to middle-income countries are burdened with out-of-pocket spending as their local health care systems have yet to incorporate autism-related services into the health care infrastructure.

Objectives. This study aimed to determine the direct costs of diagnosing and caring for children with autism and analyze its impact on the Filipino family.

Methods. The cross-sectional study consisted of a self-administered questionnaire that looked at parents’ employment status, family income, and the direct costs for consultations, diagnostic tests, therapy, education, and medications. Study participants were parents living with their child diagnosed with autism, ages 2 to 6 years old at the time of the study.

Results. One hundred fifty-eight parents participated in the survey for the cost of care for children with autism. Sixty-seven (42.4%) of parents received government or subsidized medical services for their children's consultation and/ or intervention, while the rest went to private centers or hospitals. The total costs for all evaluations that confirmed the autism diagnosis ranged from ₱1,356 to ₱44,634 and averaged ₱7,411.80 per child. Overall, the mean cost of interventions post-diagnosis, including therapy, education, medications, and developmental evaluations for the first year, was ₱38,868 or ₱3,239 per month (21% percent of the monthly expenditures for a household with an income of ₱15,000/month). The total cost of care per child was closely related to the family’s revenue in the sample population. Families with higher incomes also had higher expenditures for autism-related services.

Conclusion. Autism imposes a significant economic burden on Filipino families, particularly the minimum-wage household earners who spent a higher proportion of their budget (21%) on autism-related services. The wide range of total costs for the care of the children in the study may be explained by the wide variability of the expenses for the services, differences in access to services, socioeconomic status, and the wide variation in needs of children with autism due to the nature of the condition.
Comparison of Ketorolac and Indomethacin for the Closure of Patent Ductus Arteriosus among Preterm Infants Born at the Philippine General Hospital: A Randomized Controlled Crossover Design
Authors: Villanueva-Uy Maria Esterlita T. , Briones Carmen R. , Ortiz Edgardo M.
Published: May 2022

Background. Indomethacin has been the gold standard for the closure of patent ductus arteriosus (PDA). Still, the availability of the intravenous (IV) form has been a big issue precluding its use in the Philippines. IV ketorolac is another non-steroidal anti-inflammatory drug (NSAID) that is cheaper and more available in our country and used for post-cardiac surgery pain management among neonates.

Objectives. To compare the efficacy of ketorolac versus indomethacin in the closure of patent ductus arteriosus among preterm infants.

Methods. We conducted a randomized controlled, double-blind, crossover design, non-inferiority trial on the use of iindomethacin versus ketorolac among preterm infants with PDA. We enrolled preterm infants at 5-12 days postnatal life, diagnosed with PDA by echocardiography at the Philippine General Hospital (PGH). We excluded infants with upper gastrointestinal bleeding, renal failure, birthweight < 500 grams, septic shock, and lethal anomalies. Patients were randomly allocated between two treatment groups (indomethacin versus ketorolac). The primary outcome measure was PDA closure measured after the treatment course. Adverse events like oliguria and bleeding were recorded.

Results. A total of 27 preterm infants were randomly assigned to the indomethacin (0.2 mg/kg/dose) and ketorolac (0.6 mg/kg/dose) group. Ketorolac has a 60% success rate for PDA closure (9/15) compared to indomethacin 41.67% (5/12) (p=0.154). No renal insufficiency and bleeding diathesis were noted. Five patients died in the study, four in the group initially allocated in ketorolac and one in indomethacin. Causes of death were late-onset sepsis, bronchopulmonary dysplasia, and congenital adrenal hyperplasia.

Conclusion. The success rate of PDA closure between IV ketorolac and IV indomethacin was not significantly different. There was neither oliguria nor bleeding observed in both groups.

Purpose: The purpose of the study was to examine the influence of vendor base optimization and rationalization on the performance of parastatals in Kenya with an aim of making recommendations.

Methodology: . The study employed a descriptive research design, targeting heads and deputy heads of procurement in parastatals. The researcher prefers this method because it allows an in-depth study of the subject. Data was collected using self-administered questionnaires. The data collected was analyzed by use of descriptive and inferential statistics. A multiple regression model was used to show the relationship between the dependent variable and the independent variables. The data generated was keyed in and analyzed by use of Statistical Package of Social Sciences (SPSS) version 24 to generate information which will be presented using charts, frequencies and percentages.

Results and conclusion: The response rate of the study was 91% .The independent variables reported R value of 0.846 indicating that there was perfect relationship between dependent variable and independent variables. R square value of 0.715 means that 71.5% of the corresponding variation in performance of parastatals in Kenya can be explained or predicted by (triangle approach, twenty/eighty approach, spend categorization method and competency staircase method) which indicated that the model fitted the study data. The results of regression analysis revealed that there was a significant positive relationship between dependent variable and independent variable at (β=0.715), p=0.000 <0.05).The findings of the study indicated that triangle approach, twenty/eighty approach, spend categorization method and competency staircase method have a positive relationship with performance of parastatals in Kenya.

Policy recommendation: The study recommended that parastatals should embrace vendor base optimization and rationalization so as to improve performance and further researches should te carried out in other institutions to find out if the same results can be obtained.
Do governo eletrônico ao governo digital: a busca pela eficiência e a Lei n. 14.129/2021
Authors: Philippi Juliana Horn Machado
Published: May 2022

A partir do método hipotético-dedutivo, mediante pesquisa bibliográfica, o estudo tem como objetivo principal verificar se o uso de tecnologias da informação e comunicação (TICs) pode ser adequado para a busca pela eficiência na prestação de serviços públicos, especialmente no modelo do governo digital. Para tanto, expõe-se a relação entre as novas tecnologias e a Quarta Revolução Industrial, marcada pela ubiquidade das tecnologias, com impactos em diversas esferas, assim como na Administração Pública. O governo eletrônico é marcado pelo uso instrumental das tecnologias da informação e comunicação (TICs), ao passo que a ideia do governo aberto propicia maior participação dos cidadãos. E ainda, considerado como mais evoluído na transformação digital da Administração Pública, há o governo digital, com emprego das tecnologias para a prestação de serviços públicos, tendo em vista os direitos fundamentais previstos na Constituição Federal, especialmente seu caráter social. Não se pode deixar de observar que um dos grandes desafios para o efetivo emprego das TICs na prestação dos serviços públicos é disparidade no acesso à internet e às tecnologias, sobretudo em um país com dimensões continentais e muitas desigualdades como o Brasil. Com relação à recente edição da Lei n. 14.129/2021, não se pode perder de vista que a concepção de eficiência na Administração Pública não se limita à celeridade e diminuição de custos, pois passa também pela priorização na concretização dos direitos fundamentais, em especial os sociais, que devem ser considerados também no ambiente digital, com a prestação de serviços públicos pela internet, aplicativos e demais meios de comunicação, inclusive com a possibilidade de emprego de inteligência artificial e outras tecnologias. Parece equivocado limitar o governo digital à eficiência e à ideia de desburocratização, como propõe a Lei n. 14.129/2021, sob risco de se limitar o potencial da cultura do governo digital.

Objetivo: Objetiva-se avaliar a endogenia, dependência e representação de 16 periódicos brasileiros de turismo, no período 1990-2018, para as instituições e suas unidades da federação e grandes regiões, ano-a-ano.
Método: A coleta e montagem do banco de dados (autoria – instituições, unidades da federação e grandes regiões) foram feitas, manualmente, assim como a revisão e desambiguação de nomes. Os cálculos foram feitos por meio de ferramentas computacionais próprias.
Resultado: Em geral, a endogenia (instituições) é muito alta no primeiro ano de cada periódico, caindo, para quase todos, já no segundo ano, havendo a convergência para valores abaixo de 20% no fim da série histórica. As unidades da federação e grandes regiões apresentam resultados parecidos, porém em patamares mais elevados. A dependência revela que, para quase todos os periódicos, a instituição é muito dependente dele para produzir no campo, nos primeiros anos, mas há, logo depois, nítida e persistente tendência de queda. Para as unidades da federação e grandes regiões, há paralelo com esses resultados, com valores mais baixos e menos exceções à regra. Os resultados da representação convergem com o visto para a dependência (instituições). Nas unidades da federação e grandes regiões, é difícil detectar tendências e padrões.
Conclusões: A endogenia, dependência e representação permitem verificar a produção de instituições, unidades da federação e grandes regiões em 16 periódicos brasileiros de turismo (1990-2018). De forma geral, há nítida tendência de queda da endogenia, dependência e representação, para a maior parte dos periódicos, no que concerne esses três elementos.

Published: May 2022

Teknologi informasi membuka akses terhadap perkembangan ekonomi digital, salah satunya bisnis transportasi online. Terdapat dua layanan transportasi online terbesar di Indonesia, yaitu Gojek dan Grab. Dalam persaingan produk digital, pengalaman pengguna (user experience) adalah salah satu aspek yang penting. Penelitian ini membandingkan perubahan pengalaman pengguna terhadap dua aplikasi: Gojek dan Grab. UX Curve merupakan metode penelitian yang digunakan untuk menangkap pengalaman pengguna dalam jangka panjang berdasarkan ingatan responden. Terdapat 10 responden dengan rentang umur 17-39 tahun yang dilibatkan dalam penelitian. Masingmasing responden diminta menggambarkan lima kurva untuk masing-masing dimensi UX Curve: general UX, aesthetic, ease-of-use, utility, dan reliable untuk masing-masing aplikasi. Hasil analisis perbandingan menunjukkan bahwa pengguna Gojek dan Grab sama-sama merasakan peningkatan pengalaman pengguna sejak pertama kali menggunakan aplikasi. Pada awal penggunaan Grab dipersepsikan lebih positif daripada Gojek. Namun kemudian pengalaman penggunaan Gojek mengalami peningkatan sedangkan Grab mengalami penurunan. Walaupun pada akhirnya, pengalaman pengguna kedua aplikasi cenderung meningkat. Seluruh responden melaporkan pengalaman positif juga negatif yang mengakibatkan peningkatan atau penurunan grafik pada kurva. Alasan perubahan yang paling banyak disampaikan oleh responden terkait aspek usability dan utility.
