An endovascular guidewire manipulation is essential for minimally-invasive clinical applications; Percutaneous Coronary Intervention (PCI) is used to open narrowed coronary arteries and restore arterial blood flow to heart tissue, Mechanical thrombectomy techniques for acute ischemic stroke (AIS) to remove blood clots from the brain veins, and Transjugular intrahepatic portosystemic shunt (TIPS) for liver portal hypertension use a special needle and position a wire between the portal vein through the liver. All procedures commonly require 3D vessel geometries from 3D CTA (Computed Tomography Angiography) images (Fig. 1). During these procedures, the clinician generally places a guiding catheter in the ostium of the relevant vessel and then manipulates a wire through the catheter and across the blockage. The clinician only uses X-ray fluoroscopy intermittently to visualize and guide the catheter, guidewire, and other devices (e.g., angioplasty balloons and stents). Various types of endovascular robot-assisted systems [1, 2] are being developed to provide efficient positional control of devices, helping clinicians to mitigate therapeutical risks. The primary motions that a clinician can use to control the movement and direction of the wire are rotation and pushing/retracting from the proximal end of the wire outside the insertion point on the patient’s body. Even with these robotic devices, clinicians passively control guidewires/catheters by relying on limited indirect obser- vation (i.e., 2D partial view of devices, and intermittent updates due to radiation limit) from X-ray fluoroscopy. Modeling and controlling the guidewire manipulation in coronary vessels remains challenging because of the complicated interaction between guidewire motions with different physical properties (i.e., loads, coating) and vessel geometries with lumen conditions resulting in a highly non- linear system.
Non-local Dependencies and Contextual Information in the Interpretation of Procedural Surgical Text
Authors:   University of Verona, Italy, Fiazza Maria-Camilla
Published: June 2023

Efforts to automate mining of procedural information from surgical texts are enabling technology for future autonomous surgical robots. In building their knowledge base (or seeking to augment it if they encounter un- expected circumstances), these robots need to interface with surgical resources so far intended for human use— such as textbooks, case reports, published medical lit- erature. Knowledge mined from surgical texts forms the backbone of higher cognition mechanisms that support surgical situation awareness and autonomous decision- making, as well as verbal interaction with humans. Great progress in natural language understanding is required. Regardless of whether the information is in- tended to support monitoring processes, surgeon or performance evaluation, or (in the future) autonomous decision-making, the safety-critical nature of the domain requires a careful study of the information landscape. Surgical textbooks contain descriptions of surgical pro- cedures that are presented semi-algorithmically, often organized in phases and occasionally also in steps. Sur- geons can understand and execute the procedure from the description, so it is possible at least in principle to derive a high-level executable representation of the procedure, one which could be suitable for an autonomous robot. However, even assuming that the robot already have executable routines corresponding to elementary surgical instructions such as incising an anatomical structure, placing an object in an anatomical location (and so on), not all information necessary to parametrize a surgical action is found directly in the text, and when it is, it is not always local to where the instruction is mentioned. Some parameters that cannot be found in the text are not missing per se; rather, they are patient-specific and thus available only when the abstract procedure is instantiated. Their values can only be determined from the direct perception of the surgical scene or from patient-specific imaging.

Published: June 2023

Early detection of precancerous forms in the intestine, e.g. adenomatous polyps, can be achieved with regular screening programmes of the lower gastro-intestinal tract (GI) by means of flexible sigmoidoscopy and colonoscopy. Screening of the GI tract is of paramount importance to reduce the high death rate of patients affected by colon cancer worldwide. Nonetheless, colonoscopy typi- cally causes discomfort and often requires sedation for the patient because of its invasiveness and abdominal pain as- sociated with it. Research on robotic-assisted colonoscopy is advancing in the design of minimally invasive devices aimed at the inspection of the GI, with the goal of reducing the discomfort caused to the patient while resulting in a safer and more successful procedure [1]. Multiple loco- motion strategies have been explored to enable front-head locomotion of endoscopes, to minimise the interaction forces between the scope and the intestine wall, as these forces are typically the first cause of discomfort for the patient. Extensive studies have been conducted in the context of track-based miniaturised robots such as [2] and [3]. However, due to the fixed geometry of these systems, adapting to the variable and irregular lumen of the colon to enable full body track-based navigation is not possible. Furthermore, as per many of the robotic solution presented to date for GI screening, there is also a need to drag a tether, the frictional resistance of which grows the more the robot advances in the intestine. Soft materials properties have inspired research of mechanism to accomplish a compliant interaction with the tissue, such as the use of inflatable balloons for double balloon endoscopy. In our previous work [4], we have presented a novel robotic system for colonoscopy called SoftSCREEN. The proposed system relies on track-based locomotion and shape reconfiguration enabled by two inflatable chambers capable of displacing the elastic tracks to conform to the local geometry of the lumen, enabling full-body track navigation. In this seminal paper we have validated the proposed desing in a 2:1 scale system and demonstrated that not only is possible to reconfigure our system to always match the lumen navigated, but also to control the force applied on the walls by means of pressure regulation, and, as a result, fine tuning the traction force of our system. In this work, we present the first miniaturised and modularised prototype of the SoftSCREEN system, designed to create a sterilisable reusable expensive compo- nent and a cheap disposable component. We then evaluate this first prototype in a 1:1 scale phantom.

Over 570,000 new cases of bladder cancer are diagnosed worldwide every year[1]. It is essential to detect new tumors as early as possible to reduce the mortality rate. In addition, the muscle invasiveness of lesions should be quantified to determine the optimal treatment plan. Within the ”Next-gen in-vivo cancer diagnostics” re- search project we propose a new cystoscopy instrument consisting of an optical coherence tomography (OCT) sensor, a camera and a light source, mounted on the tip of a concentric tube robot (CTR). The camera images could then be used to create 3-D reconstructions of the bladder wall and to quantifiy changes in its texture between successive cystoscopy sessions. In addition, the camera could guide the OCT sensor to investigate the bladder wall structure at the locations of possible tumors in order to investigate the malignancy and muscle invasiveness. This research specifically reports on creating 3-D re- constructions of bladder phantoms and co-registration of successive sessions, in order to automatically detect and indicate changes in texture which might be related to the onset and growth of tumors. Several research groups performed 3-D reconstruction of the bladder based on monocular images, often in combination with a different sensor or with structured light. Lurie et al. used monocular images (2700 on average) and sophisticated algorithms to create 3-D reconstructions with sufficiently sharp textures such that thin blood vessels are made visible without interruptions [2]. Suarez-Ibarrola et al. also performed detailed 3-D reconstructions of the bladder, but an additional sensor (electromagnetic tracker or inertial measurement unit) was required [4]. Up to date no automatic detection of texture changes in successive cystoscopy sessions has been reported in literature.

Trauma to the ankle is an increasingly common injury and is a major source of long-term debility [1]. Over two million ankle injuries occur each year in the United States alone [2]. Over half a million ankle injuries require surgeries [1]. Multiple studies have demon- strated accurate reduction of the distal tibiofibular joint (syndesmosis) as a critical predictor of good clinical outcome [3], [4]. Surgical manipulation of the tibia and fibula is necessary to properly align and reduce the syndesmosis space in ankle fractures involving sprains of the syndesmosis. However, current techniques of manual reduction utilizing open or percutaneous approaches have been shown to result in inaccurate reduction of the syndesmosis [3], [4]. We propose a novel system that combines intraoperative imaging based on low- dose cone-beam computed tomography (CBCT) and 3D- 2D image registration with robotic manipulation of the fibula to precisely restore its anatomical relationship with the tibial incisura. Our long-term goal is to de- velop robotic assistance with intraoperative imaging for precise reduction of the syndesmosis, while minimizing radiation exposure to the patient and the surgical staff. The focus of this study is to investigate the feasibility of the robot design and the potential clinical workflow.

Sífilis maligna como manifestación clínica atípica de sífilis secundaria
Authors: Calderón-Wong Luis Andrés , Arguedas-Ortiz Juliana , Ulloa-Castro Maria Luisa
Published: June 2023

La sífilis maligna (SM) es una forma infrecuente de sífilis secundaria. La patogénesis es desconocida; sin embargo, se reconoce que es más frecuente en pacientes inmunocomprometidos o que presentan un mal estado de salud, principalmente en pacientes con coinfección con VIH. Dentro de las manifestaciones clínicas de la sífilis secundaria se pueden encontrar hallazgos mucocutáneos y sistémicos. La SM comparte tropismo con la sífilis secundaria, por lo que se pueden encontrar lesiones cutáneas en tronco, extremidades, mucosas, palmas de las manos, plantas de los pies y cuero cabelludo. Estas lesiones se caracterizan por pústulas diseminadas que tienden a evolucionar a lesiones nodulares con un centro necrótico o con hiperqueratosis. El diagnóstico se basa en la clínica del paciente, confirmación por microscopía de campo oscuro, serologías e histología característica, como infiltrados de linfocitos y células plasmáticas en dermis. El tratamiento de elección es la penicilina, al igual que todos los pacientes con sífilis. Al ser una enfermedad de transmisión sexual, es imprescindible evaluar a las parejas sexuales del paciente y brindarles tratamiento.
Sinovitis transitoria de cadera: Diagnóstico diferencial y abordaje diagnóstico
Authors: Brenes Escalante María Fernanda , Milla Rivas Mario Rafael , Ordóñez Portuguez Juan José
Published: June 2023

Los trastornos de la articulación de la cadera son comunes en la población pediátrica y los pacientes usualmente presentan clínica inespecífica como coxalgia y/o cojera, las cuales son motivos de consulta frecuente y tienen un amplio rango de causas desde condiciones benignas hasta malignas. La sinovitis transitoria de cadera es una condición benigna y es una de las principales causas de coxalgia y/o cojera aguda en esta población; se presenta en pacientes entre los tres y ocho años de edad y es más frecuente en sujetos masculinos. El cuadro clínico típico se caracteriza por inicio agudo de coxalgia, cojera o ambos. Es un diagnóstico de exclusión y, antes de llegar a este, se debe descartar otras condiciones que se presentan con clínica similar, pero pueden ser amenazantes para la vida del paciente o viabilidad de la extremidad afectada. El diferencial incluye artritis séptica de cadera, osteomielitis, enfermedad de Legg-Calvé-Perthes, lesiones traumáticas, tumores, entre otros. En casos de duda, se puede llevar a cabo diferentes estudios diagnósticos. El estudio de imagen de elección es el ultrasonido, el cual tiene alta sensibilidad para detectar derrame articular. Ante pacientes con dolor severo agudo y signos inflamatorios se debe sospechar procesos infecciosos como artritis séptica y, por tanto, solicitar laboratorios con marcadores inflamatorios. Como parte del tratamiento, se recomienda reposo y analgesia; los antiinflamatorios no esteroideos suelen ser suficientes. En cuanto al pronóstico, la sinovitis transitoria de cadera tiene un curso autolimitado, con resolución espontánea en cinco y siete días, sin daño articular permanente.
Political communication on social media in Latin America: unequal use of Twitter by members of parliament
Authors: Haman Michael
Published: June 2023

This article focuses on the under-researched topic of the use of Twitter by members of parliament (MPs) in Latin America. There have not yet been any thorough comparative studies on this topic, and the majority of publications on the region focus on single case studies. Previous studies have primarily concentrated on presidents, or in the case of MPs, on specific case studies. A total of 2,353,138 tweets were accessed via the Twitter API, and 3,215 MPs were examined. Regression models and correlations were used to answer research questions, and the main variables examined concerned individual characteristics of MPs (gender and age) and socioeconomic indicators of the country (number of people on Twitter, internet access, Human Development Index - HDI). As a result, this paper offers a report on how MPs in Latin America are currently utilizing Twitter. While his social network is used by more than 90% of MPs in some countries (Argentina, Colombia, Ecuador, El Salvador, Peru, and Uruguay), there are countries where fewer than half of MPs use it (Bolivia, Honduras, and Nicaragua). The results show that female MPs are more likely than male MPs to use Twitter. In addition, Twitter is being adopted more by younger MPs. Other results show that country characteristics such as internet penetration, Twitter population, and the HDI are significant predictors regarding the adoption and use of Twitter by MPs. These results are consistent with assumptions based on cost-benefit calculus. Thus, it does not make as much sense for politicians to adopt Twitter in countries where there are less people on Twitter and low internet penetration. In particular, if politicians want to be elected or inform citizens about their activities, they have an opportunity to reach voters through Twitter. However, this is only true if Twitter is used in their countries.
Body perception and frequency of exposure to advertising on social networks among adolescents
Authors: Feijoo Beatriz , Cambronero-Saiz Belén , Miguel-San-Emeterio Begoña
Published: June 2023

The marketing actions of influencers promoting unhealthy targeted products can aggravate the problem of childhood obesity and thus generate self-esteem problems. The influence of exposure to this type of sponsored content can also have an effect on the emotional well-being of adolescents. This is the context of this study, which seeks to analyze the relationship between exposure to food or body care advertising on social networks (YouTube, Instagram, and TikTok) of adolescents and their perception of their physical appearance. Online surveys were distributed between April and June 2022 to 1,055 adolescents aged 11-17 years and residing in Spain. The main results show that 16- and 17-year-olds have a heavier figure as an ideal reference, but they are also the group that presents the thinnest evaluation of their current figure. Their level of satisfaction is the lowest compared with the rest of the age groups, and they attach greater importance to the social role of a good physical appearance. Thus, exposure to advertising by influencers on social networks is directly related to lower satisfaction with their bodies. This assessment is based not so much on individual reasons related to health or personal well-being, but rather on fundamentally social reasons, and considers that physical appearance is a determining factor for social success. Therefore, it is advisable to study in more detail the beliefs that directly affect adolescents’ self-esteem to improve their critical competence in the face of this idealized content.

Définir la carence en lits d’hospitalisation pour guider le choix du besoin journalier minimal en lits. Étude d’un service d’urgences
Authors: Batard E. , Montassier E. , Le Conte P.
Published: June 2023

Objectif : Pour définir la carence en lits et guider le choix des besoins journaliers minimaux en lits (BJML) d’un service d’urgences, nous avons étudié la relation entre le nombre journalier de lits disponibles pour les patients des urgences et le délai médian journalier d’hospitalisation.

Matériel et méthodes : L’étude a porté sur les patients hospitalisés en 2022 après leur passage dans un service d’urgences adultes. La relation entre nombre journalier de lits disponibles à 18 h et délai médian journalier d’hospitalisation a été modélisée par une régression linéaire segmentée.

Résultats : Les nombres journaliers médians d’hospitalisations (1er et 3e quartiles) en médecine/UHCD et en chirurgie étaient respectivement 26 (22–31) et 12 (9–14). Le délai d’hospitalisation augmentait de façon linéaire quand le nombre de lits disponibles à 18 h était inférieur à un seuil. Ce seuil était de 29 (IC 95 %, 23–35) pour les unités de médecine/UHCD, et de 7 (IC 95 %, 5–10) pour celles de chirurgie. Ces seuils suggèrent de définir les BJML par le 33e centile du nombre journalier d’hospitalisations en chirurgie, et le 73e centile du nombre d’hospitalisations en médecine/UHCD.

Conclusion : La modélisation du délai médian d’hospitalisation à partir du nombre de lits disponibles permet de définir la carence en lits. Ces résultats pourraient être utilisés pour guider le choix des BJML dans les services de médecine/UHCD et de chirurgie.

A new classification of parasagittal bridging veins based on their configurations and drainage routes pertinent to interhemispheric approaches: a surgical anatomical study
Authors: Karatas Derya , Martínez Santos Jaime L. , Uygur Saygı , Dagtekin Ahmet , Kurtoglu Olgunus Zeliha , Avci Emel , Baskaya Mustafa K.
Published: June 2023

OBJECTIVE

Opening the roof of the interhemispheric microsurgical corridor to access various neurooncological or neurovascular lesions can be demanding because of the multiple bridging veins that drain into the sinus with their highly variable, location-specific anatomy. The objective of this study was to propose a new classification system for these parasagittal bridging veins, which are herein described as being arranged in 3 configurations with 4 drainage routes.

METHODS

Twenty adult cadaveric heads (40 hemispheres) were examined. From this examination, the authors describe 3 types of configurations of the parasagittal bridging veins relative to specific anatomical landmarks (coronal suture, postcentral sulcus) and their drainage routes into the superior sagittal sinus, convexity dura, lacunae, and falx. They also quantify the relative incidence and extension of these anatomical variations and provide several preoperative, postoperative, and microneurosurgical clinical case study examples.

RESULTS

The authors describe 3 anatomical configurations for venous drainage, which improves on the 2 types that have been previously described. In type 1, a single vein joins; in type 2, 2 or more contiguous veins join; and in type 3, a venous complex joins at the same point. Anterior to the coronal suture, the most common configuration was type 1 dural drainage, occurring in 57% of hemispheres. Between the coronal suture and the postcentral sulcus, most veins (including 73% of superior anastomotic veins of Trolard) drain first into a venous lacuna, which are larger and more numerous in this region. Posterior to the postcentral sulcus, the most common drainage route was through the falx.

CONCLUSIONS

The authors propose a systematic classification for the parasagittal venous network. Using anatomical landmarks, they define 3 venous configurations and 4 drainage routes. Analysis of these configurations with respect to surgical routes indicates 2 highly risky interhemispheric surgical fissure routes. The risks are attributable to the presence of large lacunae that receive multiple veins (type 2) or venous complex (type 3) configurations that negatively impact a surgeon’s working space and degree of movement and thus are predisposed to inadvertent avulsions, bleeding, and venous thrombosis.

Published: June 2023

Pada Masa Tanam I (MT-I) Daerah Irigasi Kedungwaru mengalami kekurangan kebutuhan air untuk pengolahan lahan. Pengolahan lahan pada kondisi eksistingpun dilakukan dengan kurang maksimal. Penelitian ini bertujuan untuk mengevaluasi neraca air dan membuat alternatif jadwal tanam sehingga intensitas tanam bertambah. Hasil analisa kondisi eksisting menunjukan bahwa  ketersedian air  mengalami defisit atau kekurangan air, sehingga intensitas tanam sebesar 179,02% dari 300% yang direncanakan dan luas tanam seluas 777,77 ha dari 1.303,35 ha luas DI.Kedungwaru. Sehingga direncanakan perubahan alternatif berupa jadwal awal musim tanam. Neraca air alternatif 1, 3, dan 4 dalam pengolahan lahan MT-I tidak mampu untuk melayani kebutuhan air yang dibutuhkan. Sedangkan untuk alternatif 2, 5, dan 6 keandalan pada masa pengolahan lahan sudah mampu untuk memenuhi kebutuhan air. Dari keseluruhan alternatif untuk MT-I dan MT-II didapatkan intensitas tanam mencapai 100%. Pada masa MT-III luas tanam mengalami perubahan dimana ketersedian air yang defisit. Pembuatan alternatif jadwal tanam dengan hanya menggeser awal tanam seperti ini masih kurang efektif. Alangkah baiknya jika disertai dengan analisis optimasi untuk memperoleh intensitas tanam dan keuntungan yang optimum bagi para petani.

The Panglima Batur Commercial Area is a shopping area which is the center of commercial activity in Samarinda City. Around Jalan Panglima Batur there are several shopping centers such as Pasar Pagi, Mesra Indah Mall, shops along Jalan Panglima Batur and the Citra Niaga Commercial Area which is a "Landmark" of Samarinda City. The obstacle faced in the area is congestion on roads, especially Jalan Panglima Batur from morning to evening. The influence of on street parking is a problem in the area. Based on the results of an analysis of the congestion conditions on the Panglima Batur road, Samarinda City, to the traffic load in the trading area around Citra Niaga and Pasar Pagi with on street parking, there was a decrease in road capacity of 53.02%, a decrease in speed of 37.96 % and a decrease in road service level (LOS) from LOS C (Q/C = 0.49) to LOS E (Q/C = 0.92). The solution to the problem is eliminating on-street parking and managing parking with the concept of parking pockets such as creating multilevel parking in the Mesra Indah Mall parking area with the concept of Public Private Partnership (KPS).

Jalan merupakan salah satu prasarana transportasi paling populer di Indonesia. Tingginya mobilitas antara kota inti dengan kota pendukung menuntut performa jalan yang memadai. Salah satu hubungan kota inti dengan kota sekitar adalah Kawasan Kedungsepur (Kendal, Demak, Ungaran, Semarang, dan Purwodadi). Kawasan Kedungsepur yang membentuk Kawasan Metropolitan ini berada di garis pantai utara Jawa. Pantura yang merupakan jalur utama Pulau Jawa dikenal telah memiliki beban tinggi sehingga mengalami penurunan performa sehingga diperlukan opsi lain bagi masyarakat pengguna. Jalan Tol Semarang – Demak dibangun untuk memenuhi kebutuhan tersebut.Jalan Tol Semarang – Demak berada di wilayah Pantai Utara jawa yang memiliki jenis tanah berupa aluvium. Material utama yang ada di area ini berupa lempung dan lanau yang memiliki daya dukung cukup rendah. Hal ini menyebabkan Jalan Tol Semarang – Demak dibangun dengan konstruksi Slab on Pile. Tentunya selain dikarenakan pengaruh Banjir Rob dan fenomena land subsidence. Perencanaan struktur dilakukan dengan data awal berupa data Uji Penetrasi Standar (SPT). Melalui nilai N dari SPT, dapat diketahui konsistensi tanah pada kedalaman tertentu. Hasil olah data menunjukkan bahwa di Zona 1 kedalaman tanah lunak mencapai 16 m dan tanah keras baru dijumpai pada kedalaman > 44 m. Di Zona 2 kedalaman tanah lunak mencapai 10 m, sedangkan tanah dengan konsistensi keras baru ditemukan pada kedalaman 40 m. Selain itu peningkatan N-SPT sangat dipengaruhi oleh penambahan kedalaman uji. Pada Zona 1 diketahui hubungan korelasi antara N-SPT dengan kedalaman uji adalah y = 0,5861x – 2,4437 dengan tingkat pengaruh mencapai 90,05%. Di Zona 2 hubungan korelasi antara N-SPT dengan kedalaman uji dinyatakan dalam persamaan y = 0.6452x - 1.6571 dengan tingkat pengaruh sebesar 81,61%.

Padi merupakan tanaman pangan utama di Indonesia karena menjadi makanan pokok lebih dari separuh penduduk negara Indonesia. Cara untuk menanggulangi serangan serangga pada tanaman padi secara efisien, ramah lingkungan, dan aman bagi kesehatan manusia, diperlukan asap cair tempurung kelapa sebagai insektisida organik. Tempurung kelapa tersusun atas lignin, selulosa dan hemiselulosa. Kandungan yang terkandung dalam komponen utama yaitu pada asap cair adalah alkohol, fenol dan asam asetat. Penelitian dilaksanakan pada bulan Agustus – November 2022 dengan rancangan acak lengkap yang terdiri dari 4 perlakuan (0% sebagai kontrol, 2%, 5%, dan 8%) dan 6 kali pengulangan dengan total 24 perlakuan. Total walang sangit yang digunakan dalam penelitian yaitu 120 ekor. Hasil penelitian menunjukkan bahwa asap cair menyebabkan perbedaan warna pada tubuh walang sangit. Warna tubuh yang lebih gelap/cokelat kehitaman diakibatkan telah masuk dan bekerjanya pestisida organik asap cair tempurung kelapa pada tubuh walang sangit. Konsentrasi asap cair tempurung kelapa yang paling efektif mengendalikan walang sangit yaitu konsentrasi 8%. Semakin tinggi konsentrasi asap cair maka semakin besar tingkat mortalitas. Berdasakan data didapatkan nilai LC50 yaitu 4,10% yang artinya, konsentrasi sebesar 4,10% efektif membunuh 50% walang sangit.
Rice is the main food crop in Indonesia because it is the staple food for more than half of Indonesia's population. The way to deal with insect attacks on rice plants efficiently, environmentally friendly, and safe for human health, requires coconut shell liquid smoke as an organic insecticide. Coconut shell is composed of lignin, cellulose and hemicellulose. The main components contained in liquid smoke are alcohol, phenol and acetic acid. The study was conducted in August – November 2022 in a completely randomized design consisting of 4 treatments (0% as control, 2%, 5%, and 8%) and 6 repetitions for a total of 24 treatments. The total number of walang sangit used in this study was 120 individuals. The results showed that the liquid smoke caused color differences in the stink bug's body. The body color is darker/dark brown due to the entry and operation of organic pesticides from coconut shell liquid smoke on the body of the stink bug. The most effective concentration of coconut shell liquid smoke in controlling stink bugs is 8%. The higher the concentration of liquid smoke, the greater the mortality rate. Based on the data, the LC50 value was 4,10%, which means that a concentration of 4.10% is effective in killing 50% of the rice bug.

Oudemansiella canarii is a wild mushroom which easy to find in nature and usually grows on wood. This mushroom is recognized as the edible macrofungi, but information on the morphological characteristics of this fungus is very limited in Indonesia. Therefore, this study aimed to identify and describe O. canarii based on morphological features as an effort to disseminate mycology information to the public. This research was conducted in the IPB University campus forest which is one of the natural habitats of this macrofungi. The fruiting bodies were observed in the field and in the laboratory. Identification was carried out based on the macroscopic and microscopic characteristics of the collected specimens. Oudemansiella canarii observed had a cream-colored cap, scales on its surface, a cap covered with mucus, free lamellae attachments, club-shaped basidia, basidiospores globose to subglobose, hyaline with thin walls, without ornamentation, and has a clearly visible guttule. This report is the first comprehensive morphological description on O. canarii from Indonesia and adds information to the diversity of Indonesian macrofungi.

This study aims to determine the effect size of digital mathematics textbooks in blended learning assisted by Schoology to improve mathematical problem-solving abilities in polytechnic students. The research was conducted at the Bali State Polytechnic (PNB), using the Research & Development method with a 4-D model (define, design, develop, and disseminate). Currently, the dissemination stage is carried out through an effectiveness test using a quasi-experiment approach, with a one-group pretest-posttest design. The subjects are PNB engineering students in 2020/2021, and 10 classes are taken by purposive sampling. Data were collected using a mathematical problem-solving ability test and analyzed using a t-test, N-Gain scores, and effect size. The results of the analysis show that the effect size of digital mathematics textbooks to improve mathematical problem-solving skills in Schoology-assisted blended learning is very large. The implication is that increasing the ability to solve mathematical problems through blended learning assisted by Schoology for polytechnic students will be quite effective if it is facilitated by digital mathematics textbooks.

The ethical conflict between the President of China and the Prime Minister of Canada at the G20 Summit in Indonesia deserves to be studied as to the causes of ethical differences between leaders. Ethical leadership, appropriate prescriptive behaviour, and promotion among staff through personal behaviour and interpersonal relationships. The focus of ethical leadership is obedience, and the content material of norms and ethical requirements varies in line with the cultural context of each country. Community members develop cognitive templates of behaviours that leaders prefer. This indicates that leaders tend to act in a manner that corresponds to their respective societal expectations of being more effective. This study uses a systematic literature review method. Ethical leadership in China is rooted in Confucian philosophy, whereas ethical leadership in Canada emphasizes performance, future orientation, and individualism. Lawrence Kohlberg on moral reasoning said that most people go through what is called the conventional cognitive level of moral development. This study provides reference material in the study of culture and cognition in ethical leadership that has not been extensively studied by researchers. This research helps people see the cultural differences that affect ethical leadership among state leaders, particularly in China and Canada. Communities can understand this difference and thus prevent conflicts in the future.
