Abstract. Sanjaya WTA, Khoirunnisa NS, Ismiani A, Hazra F, Santosa DA. 2021. Isolation and characterization of mercury-resistant microbes from gold mine area in Mount Pongkor, Bogor District, Indonesia. Biodiversitas 22: 2656-2666. Exploring novel wild-type microbes is very important to give more flexibility for bioremediation implementation. It is related to discovering strain with higher detoxification ability and more reliable degradation mechanisms. Moreover, novel strain can be used as genetic material for strain development by molecular genetic engineering and production design formulation. The aims of this experiment were to characterize and identify new mercury-resistant microbes, investigate their capacity to accumulate mercury, and analyze the reducing mercury toxicity in bioassay. Four strains of bacteria selected through the screening stage were characterized for their morphological, biochemical, physiological, and molecular genetic characteristics. Considering their characteristics and mercury resistance levels, there are two selected microbial strains: fungus strain Cladosporium halotolerans Hg32 and the bacterial strain Mycolicibacterium peregrinum Hg37 with a mercury resistance level up to 3000 mg L-1. The C. halotolerans Hg32 could remove mercury with the highest potency up to 90.72% at a mercury concentration of 100 mg L-1, while M. peregrinum Hg37 removes up to 77.10% at mercury concentrations of 10 mg L-1. Toxicity bioassay tests using fish confirmed that C. halotolerans Hg32 and M. peregrinum Hg37 had the ability to detoxify mercury in contaminated water. Both have successfully proven to reduce the mortality rate to below 5%.

Abstract. Munirah M, Wahid I, Hamid F, Wahyuni S. 2021. Short Communication: The detection of Plasmodium in mosquitoes from Sumba and Sorong districts, Indonesia. Biodiversitas 22: 2680-2684. Malaria is heading for elimination in 2030, but the disease remains prevalent in Indonesia. Therefore, this study aimed to determine a vector other than Anopheles that is potentially responsible for malaria transmission in the country's endemic areas. The mosquitoes were trapped by Kelambu trap, collected using a mouth aspirator, and stored in a tube containing silica gel. They were also examined microscopically following O'Connor identification keys, and Nested PCR was used to detect Plasmodium DNA. The number of mosquitoes collected from two areas was 1.336. In Sumba (Gaura village) district, 493 mosquitoes were captured, and the dominant genus was Anopheles (58.6%), followed by Culex (31%), Armigeres (9.9%), Aedes (0.2%), and Lutzia (0.2%). Among 843 mosquitoes collected from Sorong (Aimas), Culex was 98.9%, followed by Aedes (0.8%) and Anopheles (0.2%). The result of nested PCR found two An. sundaicus from Sumba carried Plasmodium which belongs to P. falciparum and P. vivax species (0.14%). Although we did not detect the presence of Plasmodium in mosquitoes other than the genus Anopheles, in this study, we found Anopheles species that have never previously been reported from the area, namely An. bailey and An. barbirostris from Papua and An. nivipes in West Sumba.

Abstract. Batuyong MAR, Calaramo MA, Alejandro GJD. 2021. Inventory of Rubiaceae species in Mt. Pao Range, Ilocos Norte, Northwestern Luzon, Philippines. Biodiversitas 22: 3604-3612. Botanical assessments in the Philippines are mostly conducted on declared Protected Areas (PAs). However, many remaining potentially interesting and largely unexplored floristic sites are not considered PA, one of which is the Mt. Pao Range in the Municipality of Adams, located in Ilocos Norte, Philippines. Among the flowering plant family, Rubiaceae is one with the largest number of endemic species and genera in the Philippines Thus, floristic surveys of Rubiaceae species were conducted, and collections were made from September 2019 to March 2021. A total of 39 species belonging to 13 tribes and 24 genera of the family were recorded. These constitute 7.09% of the total Philippine Rubiaceae. Of these species, 18 are Philippine endemics while two are considered narrow endemic to Mt. Pao. Two endemic genera were also found in the area Antherostele and Kanapia. According to the Updated National List of Threatened Philippine Plants, their conservation status in the Department of Environment and Natural Resources (DENR) Administrative Order No. 2017-11 found one species assessed as Critically Endangered (Antherostele callophylla). This study contributes to the data on the distribution and occurrence of Philippine Rubiaceae. Moreover, it also highlights the area's importance with the presence of threatened and endemic species as an area of concern for protection and conservation.

Background
The field of behavioural economics holds several opportunities for integrated fisheries management and conservation and can help researchers and managers alike understand fisher behaviour and decision-making. As the study of the cognitive biases that influence decision-making processes, behavioural economics differentiates itself from the classical field of economics in that it does not assume strictly rational behaviour of its agents, but rather looks for all mechanisms that influence behaviour. This field offers potential applications for fisheries management, for example in relation to behavioural change, but such applications require evidence of these mechanisms applied in a fisheries context. Thus, we have developed a systematic literature review protocol focusing on the primary question: “Which behavioural economics mechanisms influence fisher behaviour?” The aim is to provide a comprehensive overview of these different mechanisms and how they have been applied in the study of fisher behaviour.

Methods and expected outputs
The review protocol was developed in close collaboration with the International Council for the Exploration of the Sea (ICES) Working Group on Maritime Systems (WGMARS). WGMARS members were therefore considered the key stakeholders for this study, and were consulted to develop a suitable systematic review question and methodology. Three academic databases will be searched using a customized Boolean keyword search string. Research articles deemed eligible for inclusion in the systematic review are those that studied the influence of behavioural-economics mechanisms on the behaviour of marine fishers in any location, and at any scale. Insights from this literature will be collated in order to provide an overview of the relevant behavioural-economics mechanisms and actions, how effective these mechanisms are and at what scale, geographic region and in which fisheries sector they have been applied. Any fisheries management implications identified by the studies under review will also be outlined. Finally, it will be recorded whether or not ethical considerations were made in the reviewed literature, so that in the discussion it will be possible to reflect on the ethics of conducting behavioural-economics research and policy actions in a fisheries context.

Authors: Mmari Elizabeth E. , Pallangyo Eunice S. , Ali Athar , Kaale Dereck A. , Mawalla Isaac H. , Abeid Muzdalifat S. 
Published: August 2021

Background
Surgical Site Infections are a major cause of morbidity and mortality among operated patients. In spite of the accessibility of universal and national guidelines for surgical prophylaxis, recent studies surveying the present routine of prophylaxis have demonstrated overutilization of a wide range antibacterial medication for a single patient. Few studies have shown qualitatively factors influencing this and perceptions of surgeons on surgical antibiotic prophylaxis use. Unfortunately, none of these studies have been done in Tanzania.

Objective
To describe the perceptions of surgeons on surgical antibiotic prophylaxis use at an urban tertiary hospital.

Methods
A qualitative study involving in-depth interviews with surgeons was conducted in English by the primary investigator. The interviews were audio-recorded and transcribed verbatim. Systematic text condensation by Malterud was used for data analysis.

Findings
Fourteen surgeons and obstetrics and gynaecologists participated. Their perceptions were summarized into three main categories: Inadequate data to support practice; one who sees the patient decides the antibiotic prophylaxis; prolonged antibiotic use for fear of unknown. The participants perceived that choice of antibiotic should be based on local hospital data for bacterial resistance pattern, however the hospital guidelines and data for surgical site infection rates are unknown. Fear of getting infection and anticipating complications led to prolonged antibiotics use.

Conclusion
The study provides an understanding of surgical antibiotic prophylaxis use and its implementation challenges. This was partly expressed by unavailability of local data and guidelines to enhance practice. To improve this, there is a need of guidelines that incorporates local resistance surveillance data and enhanced antibiotic stewardship programmes. A strong consideration should be placed into ways to combat the fears of surgeons for complications, as these significantly affect the current practise with use of surgical antibiotic prophylaxis.
Real-time measurement of intraocular pressure variation during automatic intravitreal injections: An ex-vivo experimental study using porcine eyes
Authors: Park Ikjong , Park Han Sang , Kim Hong Kyun , Chung Wan Kyun , Kim Keehoon 
Published: August 2021

Purpose
To measure needle insertion force and change in intraocular pressure (IOP) in real-time during intravitreal injection (IVI). The effects of needle size, insertion speed, and injection rate to IOP change were investigated.

Methods
Needle insertion and fluid injection were performed on 90 porcine eyeballs using an automatic IVI device. The IVI conditions were divided according to needle sizes of 27-gauge (G), 30G, and 33G; insertion speeds of 1, 2, and 5 mm/s; and injection rates of 0.01, 0.02, and 0.05 mL/s. Insertion force and IOP were measured in real-time using a force sensor and a pressure transducer.

Results
The peak IOP was observed when the needle penetrated the sclera; the average IOP elevation was 96.3, 67.1, and 59.4 mmHg for 27G, 30G, and 33G needles, respectively. An increase in insertion speed caused IOP elevation at the moment of penetration, but this effect was reduced as needle size decreased: 109.8–85.9 mmHg in 27G for 5–1 mm/s (p = 0.0149) and 61.8–60.7 mmHg in 33G for 5–1 mm/s (p = 0.8979). Injection speed was also related to IOP elevation during the stage of drug injection: 16.65 and 11.78 mmHg for injection rates of 0.05 and 0.01 mL/s (p < 0.001).

Conclusion
The presented data offers an understanding of IOP changes during each step of IVI. Slow needle insertion can reduce IOP elevation when using a 27G needle. Further, the injection rate must be kept low to avoid IOP elevations during the injection stage.

BackgroundPatients with hepatocellular carcinoma (HCC) represent a vulnerable population potentially negatively affected by COVID-19-associated reallocation of healthcare resources. Here, we report the impact of COVID-19 on the management of HCC patients in a large tertiary care hospital.MethodsWe retrospectively analyzed clinical data of HCC patients who presented at the Vienna General Hospital, between 01/DEC/2019 and 30/JUN/2020. We compared patient care before (period 1) and after (period 2) implementation of COVID-19-associated healthcare restrictions on 16/MAR/2020.ResultsOf 126 patients, majority was male (n = 104, 83%) with a mean age of 66±11 years. Half of patients (n = 57, 45%) had impaired liver function (Child-Pugh stage B/C) and 91 (72%) had intermediate-advanced stage HCC (BCLC B-D). New treatment, was initiated in 68 (54%) patients. Number of new HCC diagnoses did not differ between the two periods (n = 14 vs. 14). While personal visits were reduced, an increase in teleconsultation was observed (period 2). Number of patients with visit delays (n = 31 (30%) vs. n = 10 (10%); p = 0.001) and imaging delays (n = 25 (25%) vs. n = 7 (7%); p = 0.001) was higher in period 2. Accordingly, a reduced number of patients was discussed in interdisciplinary tumor boards (lowest number in April (n = 24), compared to a median number of 57 patients during period 1). Median number of elective/non-elective admissions was not different between the periods. One patient contracted COVID-19 with lethal outcome.ConclusionsChanges in patient care included reduced personal contacts but increased telephone visits, and delays in diagnostic procedures. The effects on long-term outcome need to be determined.

Objective
To investigate the association between relative grip strength and the prevalence of type 2 diabetes mellitus (T2DM) independently and in combination with body mass index (BMI) in Korean adults.

Methods
The cross-sectional study includes 2,811 men and women (age 40 to 92 years old) with no history of heart disease, stroke, or cancer. Relative grip strength was measured by a handheld dynamometer and calculated by dividing absolute grip strength by body weight. Logistic regression analysis was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) of T2DM by sex-specific quintiles of relative grip strength. In a joint analysis, participants were classified into 4 groups: “weak (lowest 20% quintile one) and normal weight (BMI <25.0 kg/m2)”, “weak and overweight/obese (BMI ≥25.0 kg/m2)”, “strong (upper 80% four quintiles) and normal weight” or “strong and overweight/obese”.

Results
Among the 2,811 participants, 371 were identified as having T2DM. Compared with the lowest quintile of relative grip strength (weakest), the ORs (95% CIs) of T2DM were 0.73 (0.53–1.02), 0.68 (0.48–0.97), 0.72 (0.50–1.03), and 0.48 (0.32–0.74) in upper quintiles two, three, four, and five, respectively, after adjusting for BMI and other potential confounders. In the joint analysis, compared with the “weak and overweight/obese” reference group, the odds of T2DM [ORs (95% CIs)] was lower in the “strong and overweight/obese” group [0.65 (0.46–0.92)] and the “strong and normal weight” group [0.49 (0.35–0.67)], after adjusting for potential confounders.

Conclusion
In this cross-sectional study, greater relative grip strength was associated with a lower prevalence of T2DM independent of BMI in Korean adults. Additional prospective studies are needed to determine whether a causal association exists between relative grip strength and T2DM prevalence considering BMI.
Binomios en la enseñanza musical
Authors: Zilli Lía , Ferrero Emanuel 
Published: August 2021

En el presente artículo reflexionaremos en torno a los relatos de tres docentes de música que actualmente se desempeñan en institutos de formación de docentes (IFD) en la ciudad de Santa Fe.
Recuperaremos parte de lo dicho en tres binomios: Escuchar-Disfrutar, Arriesgar-Desarmar y Convivir-Vincular; que permitan acercarnos a la complejidad y heterogeneidad que caracterizan a las prácticas de Educación Musical (en el Nivel Superior en general y en los IFD en particular). A partir de ese acercamiento, articularemos algunas posibilidades para pensar el lugar del placer y del disfrute en su vínculo con la escucha, el riesgo como espacio de oportunidad para la transformación de prácticas docentes y el desafío de irrumpir en la enseñanza de la música desde un abordaje vincular y humano en sintonía con el convivir.
Recorrido histórico de la guitarra jazz en Santa Fe
Authors: Castellano Oscar 
Published: August 2021

A lo largo de más de 30 años la ciudad de Santa Fe (Arg.) ha desarrollado una fuerte actividad artística dentro del género del jazz. Cuenta con importantes festivales dónde el jazz ocupa un rol protagónico, como son El Festival de Jazz de Santa Fe, Trombonanza y también el Festival internacional de Percusión. Estos eventos han traído grandes figuras del género como Paquito D' Rivera, Conrad Herwig, Jeff Gardner, Ernesto Jodos, “Fats” Fernández, Remiggio Pereyra Pintos, entre otros.
Dentro de este panorama la guitarra de jazz fue acompañando el proceso evolutivo del género en la ciudad. En su recorrido diversos guitarristas realizaron importantes aportes para la comunidad santafesina del jazz y compartieron sus aprendizajes con nuevos interesados en el instrumento. Así se fue formando un árbol genealógico donde los años comenzaron a manifestar diferentes generaciones de guitarristas.
Éstas generaciones, sus principales actores, la relación entre ellos y sus influencias mutuas, sus historias de vida y su aporte para el circuito de jazz de Santa Fe entre los años 1955 a 2005 serán las temáticas de este artículo.
Historia de las mujeres, género y musicología:
Authors: Mariani Tomás Agustín 
Published: August 2021

En la primera parte de este artículo presentamos algunos hitos importantes del devenir de la historia de las mujeres en la historiografía tomando como eje a la categoría de género. Nos detenemos en los casos de Estados Unidos, apoyándonos en la perspectiva de Joan Scott (2003), y de Argentina, apoyándonos en la perspectiva de Dora Barrancos (2005). Posteriormente, articulamos la categoría de género con el devenir de la historia de las mujeres en el ámbito de la musicología.
En la segunda parte de este artículo presentamos un análisis del disco mujer/MUJER (1984) de Chany Suárez retomando herramientas presentadas en la primera parte.
Este trabajo se inscribe dentro de una investigación más amplia, que abarca referentes emergentes del folklore argentino entre el fin de la dictadura (1982-1983) y el comienzo de la democracia. En ese sentido, nuestra propuesta de análisis considera a este disco como un dispositivo de enunciación, en línea con nuestros anteriores trabajos (Mariani, 2019a; 2019b y 2020).
Canon y educación musical
Authors: Beltramino Fabián 
Published: August 2021

Este artículo sintetiza los resultados de dos investigaciones acerca del canon musical: una dedicada al relevamiento de la programación de conciertos, la otra al de la oferta académica de la formación musical. Se establece, así, una correlación entre el canon que surge de la performance y aquél que surge de la instancia formativa de aquellos que ejercen la práctica. El trabajo efectuado permite concluir que por más “abierta” que se plantee la dimensión conceptual, en la práctica, los contenidos de una educación musical basada en lo modélico y en el paradigma de lo consagrado y lo ejemplar están más que vigentes.
En cuanto a la pregunta acerca de si el repertorio es consecuencia de la formación del músico o es un factor que orienta esa formación, se propone una tercera posición, la alternativa especular, que implica aceptar que ambas dimensiones se encuentran atrapadas en una relación circular respecto de la cual resulta muy difícil pensar alguna clase de desvío.
Libertad formal frente a libertad posesiva y libertad comunal: los tres conceptos de la libertad de Isaiah Berlin.
Authors: Schwartz Girón Pedro 
Published: August 2021

Este trabajo pretende aclarar y defender la distinción entre “libertad negativa”, por un lado, y “libertad positiva” y “libertad comunal”, por otro, presentada por Isaiah Berlin. Esa distinción ha sido atacada por quienes consideran que no es acorde con la igualdad o con la fraternidad, virtudes que muchos autores progresistas colocan en el mismo plano que la libertad. En lugar de la denominación de “libertad negativa” propuesta por Berlin, se propone la de “libertad clásica o formal”. A su vez, en lugar de la denominación de libertad “positiva”, se proponen los términos de “libertad posesiva” y la “libertad comunal”. Así pues, Isaiah Berlin debería haber hablado de tres conceptos de libertad y haber destacado que los dos últimos tienen un efecto destructivo del primero. Las libertades posesiva y grupal pueden ser aspectos apreciables de una sociedad, pero no deben confundirse con la libertad personal. El fomento de las libertades posesiva y comunal viene muchas veces acompañado de invasiones de la libertad formal.
Un buen medio para un buen fin: una visión utilitarista de la democracia.
Authors: Rodríguez López Blanca 
Published: August 2021

La conexión entre utilitarismo y democracia siempre ha sido estrecha, hasta el punto de que algunos autores consideran que la democracia no es sino el utilitarismo aplicado a la política. Este punto de vista es discutible, pero sin duda los principales utilitaristas han sido defensores de la democracia, si bien sus propuestas prácticas han sido distintas, así como también lo han sido los argumentos presentados para su defensa. En este trabajo analizamos las principales causas de esas variaciones: las diferencias existentes en las propias propuestas utilitaristas de los distintos autores y la diversidad de las circunstancias históricas y políticas en que las mismas se presentaron.
