Authors: Maharani Rizqi Dwi , Dasari Dadan , Nurlaelah Elah
Published: January 2023

Konsep peluang merupakan konsep dasar yang perlu dipahami oleh siswa karena pemahaman konsep tersebut akan terus digunakan pada jenjang selanjutnya. Namun, masih banyak siswa yang mengalami hambatan dalam mempelajari topik tersebut. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis hambatan belajar (learning obstacle) siswa pada materi konsep peluang. Metode yang digunakan adalah metode penelitian kualitatif dengan pendekatan fenomenologi yang melibatkan 22 siswa SMP kelas IX dan 24 siswa SMA kelas X di dua sekolah di Kabupaten Wonosobo, Jawa Tengah, Indonesia. Pengumpulan data menggunakan triangulasi dengan pemberian tes diagnostik, wawancara guru dan siswa, serta analisis buku ajar yang digunakan (analisis dokumen). Hasil penelitian menunjukkan bahwa siswa mengalami hambatan belajar dimana kurangnya ketertarikan siswa terhadap materi konsep peluang, ketidaksiapan siswa berkaitan dengan hal teknis yang bersifat kunci dari proses pembelajaran seperti ruang sampel dan titik sampel, dan siswa masih kesulitan dalam menguasai konsep prasyarat himpunan, yaitu kesulitan memahami dalam mendaftarkan anggota suatu himpunan (ontogenic obstacle). Hambatan lain yang dialami siswa yaitu, banyaknya miskonsepsi siswa pada penyelesaian permasalahan terkait konsep peluang (epistemological obstacle) serta alur pembelajaran yang belum sesuai dengan kebutuhan dan karakteristik siswa (didactical obstacle). Hambatan-hambatan tersebut harus dipertimbangkan dalam pengembangan desain didaktik yang lebih optimal untuk mencapai tujuan pembelajaran yang diharapkan. The concept of probability is a basic concept that students need to understand because this concept will continue to be used at the next level. However, many students still have obstacles in learning this topic. This study aims to identify and analyze student learning obstacles in the concept of probability. The method used is qualitative research method with phenomenological approach involving twenty two 9th grade students and twenty four 10th grade  students in two school in Wonosobo Regency, Central Java, Indonesia. Data collection uses triangulation by giving diagnostic tests, teacher and student interviews, and analysis of the textbooks used (document analysis). The results showed that students have learning obstacle which there was a lack of student interest in the concept of probability, students' unpreparedness related to key technical matters of the learning process such as sample space and sample points, and students still have difficulty mastering the concept of sets, they have difficulty writing members of a sets (ontogenic obstacle). Another obstacle is the number of misconceptions in solving problems of probability (epistemological obstacle) and the learning trajectory that is not in accordance with the needs and characteristics of students (didactical obstacle). These learning obstacles must be considered in the development of a more optimal didactical design to achieve the expected learning objectives.

Comparison of Torching and Glyphosate Applications for Japanese Stiltgrass (Microstegium vimineum) Control
Authors: Payne Geoffrey , Evans Jim , Murdock Ethan , Derr Jeffrey
Published: January 2023

Trials were conducted over three years to evaluate two torchings, torching followed by glyphosate application, raking followed by glyphosate application, and one or two yearly applications of glyphosate for control of Japanese stiltgrass. A single glyphosate application in fall reduced Japanese stiltgrass cover but the percent cover increased during the following growing season. Either two torchings or two applications of glyphosate per season for three years gave excellent Japanese stiltgrass control but plants recovered the year after treatments ended. Raking away leaf litter in spring increased Japanese stiltgrass cover. Torching followed by a glyphosate application was less effective than 2 applications of glyphosate. Treatments would need to be repeated for over three years to eradicate Japanese stiltgrass from a site.

Species used in this study: Japanese stiltgrass, Microstegium vimineum (Trin.) A Camus.
Propagation of Herbaceous and Woody Perennials in Submist and Overhead Mist Systems
Authors: Burnett Stephanie E. , Peterson Bryan J.
Published: January 2023

Submist aeroponic propagation systems apply mist to the bases of cuttings, rather than from overhead. These systems improve rooting in some plant species and reduce water usage compared to overhead mist systems. Submist systems, which were supplemented with infrequent overhead mist, were used to propagate stem cuttings collected from six plant species: bluestar (Amsonia tabernaemontana Walter), purple smoke false indigo (Baptisia australis x B. alba ‘Purple Smoke'), threadleaf coreopsis (Coreopsis verticillata L.), panicle hydrangea (Hydrangea paniculata Siebold), sweetgale (Myrica gale L.), and ninebark (Physocarpus opulifolius (L.) Maxim ‘Diablo'). The submist systems were compared to traditional overhead mist with a solid propagation medium. Rooting was better in overhead mist for cuttings of threadleaf coreopsis and purple smoke false indigo. Rooting was comparable between systems for all other species (bluestar, panicle hydrangea, sweetgale, and ninebark). In the submist systems, water usage was reduced by 67% compared to overhead. This is probably due to reduced evaporative water loss and more targeted application of water directly to cuttings, resulting in less water lost on the ground or benchtops.

Species used in this study: Amsonia tabernaemontana Walter, Baptisia australis x B. alba ‘Purple Smoke', Coreopsis verticillata L., Hydrangea paniculata Siebold, Myrica gale L., Physocarpus opulifolius (L.) Maxim ‘Diablo'.

Chemicals used in this study: KIBA (potassium salt of indole-3-butyric acid).
Castración química versus garantismo penal: la popularización de la política criminal colombiana
Authors: Sáenz Salas Gilberto Alfonso , Angarita Vargas Cristian Javier
Published: January 2023

El presente escrito es resultado de una investigación cualitativa en la que se analiza la idoneidad y efectividad de la aplicación de la castración química como pena accesoria contra delitos sexuales a menores de 14 años en Colombia y las implicaciones sociales, legales y políticas de su implementación. Para complementar este texto, se determinó con base en el derecho comparado internacional el tipo de penas, la forma, casos y eventos en que se aplica la castración química como pena para abusadores de menores; se estableció el modelo de derecho penal consagrado en la Constitución Política de Colombia, y se examinó las implicaciones físicas y psicológicas que la castración química acarrea en el sujeto que se interviene. De lo anterior surgió el interrogante ¿Cómo se está popularizando la política criminal colombiana? Según lo expuesto en el análisis subsecuente, se argumentó que la castración química científicamente no demuestra un porcentaje convincente de efectividad, contraría el modelo penal colombiano y los fines de la pena, además de no propender por la garantía de los derechos de los niños. Por tanto, al implementarla, la política criminal se permea por el populismo punitivo que algunas vertientes políticas pretenden usar a su favor
Derecho Social y pobreza en tiempos de pandemia: una aproximación comparativa entre México y España
Authors: GESTO RODRÍGUEZ JOSE
Published: January 2023

El Desarrollo Social tiene la obligación de desarrollarse bajo las particulares interpretaciones de la condición humana, de tal manera que sus valores fundamentales estén orientados a poner fin a la pobreza y minimizar las condiciones de marginalidad a las que están sometidas miles de millones de personas en el mundo, en la defensa de una vida digna. A través de una revisión documental, se hace un análisis de la pobreza en el marco del Derecho Social, como el problema de violación a los derechos humanos que demanda mayor atención a nivel planetario, y cuya erradicación se considera cimentada en el diseño de políticas públicas y acciones gubernamentales amparadas en la perspectiva jurídica emanada del conjunto de leyes, disposiciones y normas dirigidas a la protección de personas y grupos de la sociedad económicamente débiles. Se concluye que los países en desarrollo y de ingresos limitados, como México, son los que más sufren los efectos sociales y económicos de la pandemia, pues destinan menos recursos a la salud pública y a la ayuda social, en comparación con países desarrollados como España.
Geochemical features of volcanites of the northern part of the Tagil structure as a reflection of the evolution of the paleozone of subduction
Authors: Petrov G. A.
Published: January 2023

Research subject. Volcanogenic formations of the northern part of the Tagil megazone.

Material and methods. Volcanites of the Tagil paleo-island arc system and its frames were studied, including basalts and andesibasalts of the following formations: Khomas’inskaya O1-2, Shemurskaya O3-S1, Pavdinskaya S1, Imennovskaya S1-2, Turinskaya S2-D1, Perevozskaya D1, Krasnotur’inskaya D1, Limkinskaya D2-3, as well as dolerites of the Ivdel complex D3. Silicate (XFA) analyses and determination of rare elements by ICP-MS method were performed. The obtained data was analyzed using discrimination and spider diagrams, as well as indicator geochemical parameters.

Results. The geochemical parameters reflecting the degree of depletion of the host rocks of magmatic chambers, as well as the influence of fluids released during the dehydration of rocks of subducted slabs, quite definitely demonstrate an increase in the role of subducted material in the composition of island-arc magmas. This allows the onset of the subduction process, sharp changes in the conditions of its functioning and the time of its completion to be determined.

Conclusions. The obtained geochemical data confirms the existing concepts about the onset of the subduction process at the end of the Middle – beginning of the Upper Ordovician, restructuring (jumping?) of the subduction zone in the Lower Devonian and completion in the Upper Devonian.
Formation conditions of quartz deposits in the Southern Urals: Fluid inclusion data and IR spectroscopy
Authors: Ankusheva N. N. , Shtenberg M. V. , Korekina M. A.
Published: January 2023

Research subject. Quartz veins of the Svetlorechenskoye, Karayan, Gora Khrustalnaya and Tolstikha quartz deposits in the Southern Urals.

Methods. An optical study of quartz was performed using an Olympus BX51 optical microscope. A fluid inclusion study was performed using a thermostage TMS-600 (Linkam) equipped with the LinkSys V-2.39 software and an Olympus BX51 optical microscope (South Urals State University, Miass). The fluid composition in the inclusions was estimated from eutectic temperatures. Fluid salinity was calculated based on the melting temperatures of crystalline pha ses. Registration of infrared spectra was carried out using an infrared Fourier spectrometer Nicolet-6700 Thermo Scientific (SU FRC MG UB RAS, Miass). The spectra were processed using the OMNIC Thermo Nicolet software package and the Peakfit program. The extinction coefficients for calculating the concentration of molecular water and OH-groups were used from.

Results. The veins are composed of coarse-grained milky-white quartz. The fluid inclusion data shows that the quartz veins were deposited from similar in composition NaCl-H2O fluids with salinities of 3–9 wt % NaCl eq. and at temperatures ranging from 100 to 280°C. Quartz in the Tolstikha deposit was deposited at the highest temperatures. According to IR spectroscopy data, quartz in the studied deposits is characterized by high contents of molecular water and average concentrations of Al-OH groups. According to the content of OH-groups, quartz in the Tolstikha deposit approaches industrial granulated quartz used in the production of high-purity quartz concentrates.

Conclusions. Quartz veins in the studied deposits formed at temperatures ranging from 100 to 280°C. The salinity of inclusions in quartz ranged from 10 to 3.5 wt % NaCl eq. Mineral-forming fluids were of Na-chloride or Na-K-chloride composition, which indicates quartz crystallization during the post-diagenetic (metamorphic) transformation of rocks. Quartz in the studied deposits is characterized by a specific ratio of water and Al-OH, which is associated with the conditions of deposit formation and incompleteness of quartz metamorphism processes therein.

Incorporating Prognostic Gene Expression Profile Assays into the Management of Cutaneous Melanoma: An Expert Consensus Panel
Authors: Zakria Danny , Brownstone Nicholas , Berman Brian , Ceilley Roger , Goldenberg Gary , Lebwohl Mark , Litchman Graham , Siegel Daniel
Published: January 2023

Background: Cutaneous melanoma (CM) guidelines put forth by the eighth edition of the American Joint Committee on Cancer (AJCC8) and the National Comprehensive Cancer Network (NCCN) do not currently account for lesion genomics when assessing prognosis. Gene Expression Profile (GEP) tests have become a widely adopted tool to help clinicians identify patients at higher risk for metastasis and recurrence.

Objective: To review the available literature that has been published since a consensus panel in 2018 on three commercially available GEP tests used in the prognostic assessment of CM and create updated guidelines and consensus statements for their optimal use.

Methods: A comprehensive literature search of PubMed and Google Scholar was conducted for relevant English-language original research articles, meta-analyses, and systematic reviews published from 2019 through 2022. A panel of 6 key opinion leaders in dermatology with specialized expertise in diagnosing and managing CM then convened to review the articles and create guidelines. A modified Delphi process was used to approve each statement. The panel assigned each article a level of evidence and each consensus statement a strength of recommendation using Strength of Recommendation Taxonomy (SORT) criteria.

Results: The literature search identified 785 articles that met the search criteria. Of these, there were 22 articles that validated the 31-GEP test, 2 that validated the 11-GEP test, and 7 that validated the 8-GEP + CP test. The panel unanimously approved 6 usage guidelines and 5 consensus supporting statements for the appropriate use of these tests.

Conclusion: Based on the currently available literature, GEP tests provide valuable information beyond AJCC8 and NCCN guidelines for the prognostic assessment of CM. There are significantly more validation studies supporting the use of the 31-GEP test compared to the 11-GEP test and the 8-GEP + CP test.

Authors: Bury Jordan , Igelman Sean , Shamma H Nicholas , Trevino Julian
Published: January 2023

Syringofibroadenoma is a rare adnexal tumor which is derived from the acrosyringial cells of the eccrine ducts. The presentation of this lesion is variable and nonspecific, making the diagnosis, based off presentation alone, difficult. With a wide differential, more information is necessary in order to properly diagnose. Histopathological findings for syringofibroademona have distinct pathological features. Histological features are reviewed and options for treatment are discussed.
The Incidence of Imprecise ICD-10 Coding in Patients with Cutaneous T-cell Lymphoma: A MarketScan Database Study
Authors: Sun Haorui , Helm Matthew , Svoboda Ryan
Published: January 2023

Background: The term “Primary Cutaneous T-cell Lymphoma” (primary CTCL), although used largely interchangeably with mycosis fungoides in the past, actually  represents numerous non-Hodgkin lymphomas with highly variable and distinct characteristics. Accuracy of claims-based research studies of CTCL hinge on the precision of ICD-10 coding, but the incidence of imprecise coding for CTCL has not been extensively studied.

Objective: To determine the incidence of imprecise ICD-10 coding in CTCL patients in a large, commercial claims database.

Methods: We analyzed the Marketscan database from October 1, 2015 to December 31, 2018 to determine the proportion of patients designated only with the generic CTCL code in the absence of a code for a more specific diagnosis.

Results: Of 3,953 patients meeting the criteria for inclusion, only 107 (2.7%) had a generic CTCL code without a more specific diagnosis code.

Conclusions: These results suggest that the majority of CTCL claims are precisely coded, although until future studies investigate the accuracy of diagnosis, the results of claims-based studies in the realm of CTCL should be interpreted with caution.

Published: January 2023

While giant congenital melanocytic nevi are rare lesions in the pediatric population, malignant transformation within these lesions remains even more rare. A 22-month-old male patient developed a 6.5 mm Clark’s Level IV melanoma within a giant congenital nevus with an activating NRAS variant. The need for frequent surveillance and screening of giant congenital melanocytic nevi is essential to identify early signs of melanoma, even in the pediatric population.
Analysis of gravity anomaly decomposition and depth to basement, case study: Cenozoic Bogor Basin, Indonesia.

Published: January 2023

The Cenozoic Bogor Basin situated on the SE edge part of Sunda shelf is presumed to have hydrocarbon potential on its turbidite deep-water play. The deep subsurface geometry of this basin may play an important role, yet unexplored, to the hydrocarbon exploration. The gravity method is advantageous to illuminate the subsurface structure on the arbitrary depth and various sources. Eight-hundred-thirty-eight points of ground-based gravity survey were collected on roughly one kilometer spacing in the North of Bandung to Pamanukan region covering the Cenozoic Bogor Basin on the Subang-Purwakarta segment to generate complete Bouguer anomaly (CBA) map. This study examines the two robust methods of gravity anomaly decomposition (i.e., polynomial trend surface and upward continuation) by using multiple parameters to match the geological background. Radially averaged power spectrum was used to estimate the depth of anomalous source corresponds to the top of basement layer and resulting 4 km basement depth in North West Java basin and below 1 km on Tangkuban Parahu volcanic zone. The resulting estimated depth of Cenozoic Bogor Basin was evaluated by the matched a priori published data on those two areas and revealed the depth of depocenter (deepest sediment) on the Cenozoic Bogor Basin is up to 9 km, quite a deeper extent than previously assumed.

Entre respect de la religion et ordre public : les obsèques des gens de théâtre au XIXe siècle
Authors: Bodineau Pierre
Published: January 2023

Longtemps, l'Eglise catholique refuse l'inhumation des comédiens en terre consacrée. Le Concordat et ses textes d'application n'ont pas réglé la question, comme le montre la mort de Mademoiselle Chameroy. Mais après la Restauration, l'opinion publique n'accepte plus les refus d'accueillir dans une église les corps d'illustres gens de théâtre comme Mademoiselle Raucourt ou l'acteur Philippe ; ces obsèques refusées se transforment alors en vastes manifestations populaires, même si l'Etat constate « qu'on ne peut forcer les portes du temple ».
Objectivity in Research: From Eurocentrism via Decolonisation to Transmodernity
Authors: Athreya Aditi
Published: January 2023

By the end of the 1960s, most colonies had become independent nations. However, the resulting changes in the world order have done little to modify the ‘colonial’ attitudes of universities in the Western world. This article is a personal, reflexive account of an India-born doctoral researcher in Belgium. Like universities around the world, KU Leuven, the university where the author conducted her research, plays a key role in what Michel Rolph Troulliot calls ‘the production of history’. Hired by the Department of History to research the role of missionaries in education in independent India, she discusses her struggle to decolonise ‘knowledge production’ – not only due to the university’s Eurocentrism during the pandemic, but also because of the ivory tower approach that the author had to take towards her research.
Ethno-photographie de l’(in)visible : rituels chamaniques et écoféminisme au Yucatán (Essai photographique
Authors: Farahmand Manéli
Published: January 2023

Cet article présente les résultats d’une recherche ethno-photographique menée au sud-est du Mexique, qui porte sur les renouveaux chamaniques d’inspiration maya. Y sont discutés des aspects méthodologiques, tels que les usages anthropologiques de la photographie, la complémentarité entre ethnographie et photographie, et les avantages d’un tel dialogue pour comprendre les réalités sociales. Proposant une analyse de ces milieux à travers la notion d’écoféminisme, nous verrons que le rapport établi entre femmes et nature et des concepts tels que la Terre-Mère constituent le pivot alimentant un univers symbolique qui questionne les dynamiques de genre. Illustrées par des photographies, les analyses présentées dans cet article sont le résultat de notre insertion dans un terrain où la plupart des pratiquant· es sont des femmes thérapeutes alternatives. Néanmoins, elles restent marginalisées sur une scène religieuse dominée par des hommes. L’outil de l’image articulé aux observations directes et à l’analyse d’entretiens permet de souligner les dynamiques de visibilité et d’invisibilité, mais aussi un discours anticolonial passant par la revalorisation des héritages mayas.
Sequential Disproportionation Enables Aggregation of Four Electron-Holes at a Hypervalent Iodine Center
Authors: Thai Phong , Frey Brandon , Figgins Matthew , Thompson Richard , Carmieli Raanan , Powers David
Published: January 2023

The interfacial electron transfer events that underpin electrochemistry effect one-electron oxidation or reduction of substrates. In contrast, selective bond-forming and -breaking in synthetic chemistry requires the choreographed management of two-electron steps. Thus, application of electrochemistry in synthesis requires strategies to aggregate multiple redox equivalents to engender multi-electron reactions. Here we demonstrate that sequential disproportionation reactions can enable selective aggregation of two- or four electron-holes at a hypervalent iodine center. Disproportionation of an anodically generated iodanyl radical (i.e., I(II) species) affords an iodosylbenzene derivative (i.e., I(III) species). Subsequent iodosylbenzene disproportionation can be triggered to provide access to iodoxybenzene (i.e., I(V) species). Both the transient iodanyl radical intermediate that engages in disproportionation to afford I(III) species and the O-bridged bis-I(III) compound that mediates iodosylbenzene disproportionation to afford I(V) species have been directly characterized. These results represent the first example of iodanyl radical disproportionation as a means to access I(III) compounds and demonstrate aggregation of four electron at the one-electron potential by selective and sequential disproportionation chemistry.

Published: January 2023

Purpose: This study explores critical factors that create the operating conditions within which Ghana’s textile and apparel value chain operates.

Design/methodology: A qualitative case study approach was used to conduct the study.  The study design adopted was a documentary analysis of multiple sources to develop an in-depth understanding of the value chain’s ecosystem.

Findings: The results of the study revealed that Ghana’s strategic location, government policies, and natural resources, among several others, were the enabling factors of the textile and apparel value chain. Implication for further research, practice and policy development and implementation in Ghana and other developing countries is outlined.

Research Limitations: It focused on analysing the enabling environmental factors of the textile and apparel value chain at the industry level.

Practical Application: This paper serves as a useful guide for brands that are seeking a place to source merchandise and potential domestic and foreign investors seeking to establish businesses.

Social Implication: There is a need for more resilient plans and strategies by the government to ensure the continuous growth of the industry to further unlock more investment opportunities for this significant sector of Ghana’s economy.

Corpus Study of The Choice of Personal Pronouns in Social Media Chats Among Tertiary Students
Authors: Osafo-Adjei L. , Tetteh U. S. , Tieku E. A.
Published: January 2023

Purpose: Sociolinguistics variables such as age, gender and social class, among others, are said to bring the difference in the ways humans communicate. In this essence, this study investigated how age brings out the difference in the use of pronouns between three generational groups

Design/Methodology/Approach: Group WhatsApp chats were collected from three generational groups of students based on their willingness to give it out for analysis.  These three generational groups are postgraduate students and undergraduates (Level 100, Level 400). These groups were randomly collected from over four hundred (400 students of the University of Ghana and the University of Cape Coast in Ghana based on convenience. A quantitative research design was adopted for this study with the help of a corpus tool (AntConc) to analyse the huge data gathered based on percentages.

Findings: This study found out that postgraduates and undergraduates (Level 100) use the first-person singular pronoun but postgraduates, especially those who represent the older generation tend to use the first-person pronoun more often while the second undergraduate group members (Level 400) use the third person pronouns.  The study, per the findings, concludes that people tend to affiliate with others when they are young and lose group affiliation as they grow.

Research Limitation: The study was limited to WhatsApp group chats of university students within the undergraduate and postgraduate academic levels who permitted their chats to be used. This resulted in a narrow scope for the groups used.

Practical implication: The study reveals the preference or choice of pronoun usage among people based on their ages and the groups they affiliate more with. People may thus become more conscious of the choice they make of pronouns for usage as they become older or affiliate with older people.     

Social Implications: the study re-examines existing literature on the use of adverbs, especially personal pronouns. Since many studies have been done on the use of adverbs, this adds a new strand of knowledge to existing ones on the subject.

Originality/Value: It provided empirical data on the demographic, precisely age characteristics of the subjects used for the research that affects their choice of personal pronouns among themselves and others.

Published: January 2023

Purpose: This study examined the use of digital smartphone interaction for civic and public communication in the public sphere. It focuses on how policymakers perceive digital public communication among youths who constitute the majority of smartphone users in Tanzania.

Design/ Methodology/ Approach: It is designed as a case study involving a qualitative data collection method. Semi-structured interviews were conducted with policy experts in Dar es Salaam city in Tanzania.

Findings: Outcomes show that policy experts mainly focus on digital economic capacity building and less on the opportunities for developing civic and public communication as an important component of societal development.

Research Limitation: The study is designed as a case study thus limiting the generalisation of findings.

Practical implications: The study suggests policy guidelines for facilitating youths’ participation in the public sphere as a strategy to guide the utilisation of smartphones to promote engagement in civic and public life specifically for youths as a trajectory towards societal development.   

Social implications: The study creates awareness among youths to use smartphone interaction to participate in civic and public communication as an emerging crucial aspect of societal development in the digital era.

Originality/ Value: The study will contribute to improving citizens’ knowledge of civic and public engagement via new media for achieving development.

The eye-fundus photograph is widely used for eye examinations. Accurate identification of retinal blood vessels could reveal information that is helpful for clinical diagnoses of many health disorders. Although several methods have been proposed to segment images of retinal blood vessels, the sensitivity of these methods is plausible to be improved. The algorithm’s sensitivity refers to the algorithm’s ability to identify retinal vessel pixels correctly. Furthermore, the resolution and quality of retinal images are improving rapidly. Consequently, new segmentation methods are in demand to overcome issues from high-resolution images. This study presented improved performance of retinal vessel segmentation using a novel edge detection scheme based on the phase stretch transform (PST) function as its kernel. Before applying the edge detection stage, the input retinal images were pre-processed. During the pre-processing step, non-local means filtering on the green channel image, followed by contrast limited adaptive histogram equalization (CLAHE) and median filtering, were applied to enhance the retinal image. After applying the edge detection stage, the post-processing steps, including the CLAHE, median filtering, thresholding, morphological opening, and closing, were implemented to obtain the segmented image. The proposed method was evaluated using images from the high-resolution fundus (HRF) public database and yielded promising results for sensitivity improvement of retinal blood vessel detection. The proposed approach contributes to a better segmentation performance with an average sensitivity of 0.813, representing a clear improvement over several benchmark techniques
PENGARUH BUKAAN RUANG TERHADAP SENSE OF SACRED SPACE JEMAAT (OBJEK STUDI: GEREJA ST. GABRIEL BANDUNG)

Published: January 2023

Abstrak - Gereja St. Gabriel adalah rumah Allah dan wadah bagi umat Katolik beribadah. Gereja Katolik St. Gabriel memiliki konsep yang mengutamakan keterhubungan antara manusia dengan Tuhan, manusia dengan manusia, dan juga manusia dengan lingkungan. Kenyamanan ruang merupakan faktor penting dalam mendukung suasana beribadah, sehingga Gereja St. Gabriel memperkuat konsepnya dengan konsep desain pasif dan ekologis. Konsep tersebut diwujudkan melalui transparansi dan keterbukaan bangunan gereja yang besar terhadap lingkungannya, untuk mengoptimalkan pencahayaan dan penghawaan alami.  Hal tersebut yang membuat wujud fisik Gereja St. Gabriel memiliki perbedaan dengan Gereja Katolik pada umumnya, yang relatif tertutup dengan bukaan terbatas, untuk meminimalisasi gangguan suara dari luar guna membentuk suasana ibadah yang lebih sakral. Pengalaman ruang dalam gereja akan mempengaruhi suasana ibadah dan pengalaman spiritualitas jemaat saat melaksanakan kegiatan ibadah. Suasana dan pemaknaan ruang yang tidak hanya dipersepsikan secara visual saja, namun dapat dipengaruhi juga dengan indera pendengaran bahkan hingga ke indera penciuman. Oleh karena itu, penelitian ini menarik untuk dilakukan, untuk memahami bagaimana sebuah bukaan ruang di bangunan ibadah membentuk sense of sacred space bagi jemaat nya.

Penelitian ini menggunakan pendekatan kualitatif yang disampaikan secara deskriptif. Data dikumpulkan melalui observasi lapangan, studi literatur, dan menyebarkan kuesioner kepada jemaat gereja. Data dianalisis sesuai dengan kajian teori yang digunakan dan juga dari hasil kuesioner mengenai sense of sacred space jemaat terhadap bukaan di Gereja St. Gabriel. Hasil penelitian menunjukkan bahwa sense of sacred space jemaat dapat terbentuk jika suasana ruang ibadah tenang dan kondusif. Bukaan ruang memiliki peranan penting dalam membentuk suasana tersebut. Maka, dapat disimpulkan bahwa melalui kualitas visual dan audial yang dihasilkan dari bukaan, yang memiliki perbandingan peranan sebagai penyangga audio – visual lebih besar dibandingkan peranan sebagai penyaring cahaya, akan menciptakan sense of sacred space jemaat dalam Gereja St. Gabriel.

Kata Kunci: Bukaan Ruang, Gereja Katolik, Sense of Sacred Space.

Дошкільний вік важливий для росту і розвитку дітей розвитку. Відзначається швидким розвитком інтелекту та моторики дітей. Ця фаза включає відповідний час для знайомства дітей з водними розвагами та навчання базовим навичкам плавання. Плавання є цінним навиком для дітей. Крім того, що вони допомагають їм залишатися в безпеці, це також форма багатоцільових вправ, які розслаблюють, розважають, які можна виконувати в будь-який час і які становляться терапевтичними діями для створення регулярних рухів. Мета дослідження – обґрунтування ефективності застосування засобів плавання в дітей 4–5 років для підвищення рівня їх фізичної підготовленості. Об’єкт дослідження – фізкультурно-оздоровчі заняття з плавання. Суб’єкт дослідження – діти 4–5 років. Предмет дослідження – показники фізичної підготовленості дітей дошкільного віку. Гіпотеза дослідження – заснована на припущенні про позитивний вплив засобів плавання на показники фізичної підготовленості дітей дошкільного віку. Методи дослідження – аналіз і узагальнення літературних джерел з теми дослідження; педагогічні спостереження за навчально-виховним процесом, педагогічний експеримент, тестування показників фізичної підготовленості дітей дошкільного віку, методи математичної статистики. Практична значимість роботи – результати можуть бути використані з метою оптимізації фізичного виховання в дошкільному навчальному закладі. Результати дослідження. У результаті застосування засобів плавання дітей 4–5 років відмічено достовірний приріст якості виконання хлопчиками ходьби та стрибків, а дівчатками – лазіння, стрибків та метання. Кількість безпомилкового виконання основних рухів у хлопчиків і дівчаток після застосування спрямованого навчання склала у дітей від 83% до 100%. Наприкінці дослідження достовірно підвищилися показники фізичної підготовленості дітей за всіма тестами, окрім метання м’яча. Відносний приріст показників у дівчаток склав від 22 до 289%, у хлопчиків – від 12 до 162%. Найменші прирости у дітей були у метанні м’яча – від 5 до 9%. У хлопчиків та дівчаток найбільший приріст показників зафіксовано у стійці на одній нозі і вистрибуванні вгору за 5 с. А найменший – у метанні тенісного м’яча на дальність і бігу на 20 м.

Marija Hel, „Jak się już za to wzięliśmy, to trzeba walczyć do końca”. Historia oporu ukraińskiej dysydentki w ZSRR
Authors: Doboszewska Alina
Published: January 2023

Opowieść Mariji Hel, jednej z ukraińskich dysydentek działających w ZSRR od lat 60. do 80. XX w., ukazuje drogę życiową osoby, która pomimo ponoszonych kosztów, zarówno w życiu osobistym, jak i zawodowym, sprzeciwiała się systemowi totalitarnemu. Narratorka świadomie stawiała czoła pojawiającym się wyzwaniom. W jej historii życia jest wiele wątków: powojenne przesiedlenia, kolektywizacja w Zachodniej Ukrainie, odnowienie Ukraińskiej Cerkwi Greckokatolickiej; ponad wszystko jednak wybija się codzienna działalność środowiska dysydenckiego w radzieckiej Ukrainie.
