Grief is the physical or mental suffering experienced after a major loss, usually the death of a loved one. It is a universal experience, but sociocultural factors, such as cultural or ethnic identity and religious beliefs predict and shape the expression of grief. The circumstances under which people are experiencing grief during the coronavirus outbreak have adversely affected the grieving process. Unexpected deaths, social distancing rules and visitor restrictions in healthcare facilities have posed a heavier burden on the loss and have heightened the risk of grievers experiencing complicated or persistent grief. This concern led us, as early career psychiatrists (ECPs) from 14 different countries connected by the Early Career Psychiatrists Section of the World Psychiatric Association (WPA), to share our country-specific experiences on the mourning, grief tradition, and burial rites during the COVID-19 pandemic. In this paper, we discuss our experiences, similarities and differences with relation to the: ‘Effect of the pandemic on mourning’, ‘Restrictions and Guideline on burial rites due to the pandemic’, ‘Effect of the pandemic on social support’ and ‘Role of media and telecommunication on mourning practices and burial rites’. We conclude that while telecommunication means have attempted to bridge the gap and provide some form of social connectedness, the total and global effect of the pandemic is yet to be fully seen and understood.

Background

There is an ongoing discussion about the advantages and disadvantages of different surgical positions (semi-sitting and lateral position) for vestibular schwannoma surgery. Each position has its advantages, disadvantages, challenges, and risk profiles. The objectives of this study are to compare the effects of different surgical positions (semi-sitting and lateral position) on the outcomes of large vestibular schwannoma, primarily including effectiveness and safety.

Methods

In this single-centre, open, randomized controlled trial, we will recruit a total of 116 participants according to the inclusion and exclusion criteria who will be randomized to an experimental group or control group. Patients will undergo operations in semi-sitting and lateral positions. The primary endpoint will be the percentage of gross total resection. The secondary endpoints will include the facial nerve function, hearing preservation, surgical position placement time, time of operation (skin-to-skin surgical time), hospital stay, total hospitalization fee, and complications. The follow-up period will be at least 12 months, during which time patients will be evaluated both clinically and radiologically.

Discussion

This issue is still debated after 30 years since the first large comparative study was published in 1989, so the study will be useful. Therefore, more high-quality studies are required to compare clinical outcomes, complications, and other factors associated with these two positions.

Published: June 2022

Background

Although visceral aneurysms are relatively rare, it can be life-threatening in case it ruptures. We report a case of Mirizzi syndrome accompanied by a pseudoaneurysm that ruptured into the gallbladder.

Case presentation

The patient was a 73-year-old woman with persistent gastrointestinal bleeding and progressive jaundice. Examination revealed a pseudoaneurysm in the gallbladder artery or hepatic artery branch, and biliary hemorrhage due to gallbladder perforation was suspected. Urgent abdominal angiography revealed a pseudoaneurysm measuring 50 × 32 mm that had ruptured directly from the right hepatic artery or the cystic artery into the gallbladder. The pseudoaneurysm was successfully coiled and the bleeding was stopped. The presence of ongoing obstruction due to Mirizzi syndrome resulted in an emergency cholecystectomy being performed on the same day. On removing the impacted gallstone from the neck of the gallbladder, we found an obstruction between the lateral wall of the common bile duct and the gallbladder, this condition was diagnosed as Mirizzi syndrome with a biliobiliary fistula. After removing the impacted gallstone, a T-tube was inserted into the common bile duct. Bile leakage was observed postoperatively, but it improved with drainage. The patient fully recovered.

Conclusions

We present our experience with a case of Mirizzi syndrome accompanied by a ruptured pseudoaneurysm successfully treated with coil embolization followed by cholecystectomy. In this case, the pseudoaneurysm may have been caused by inflammation due to cholecystitis or compression of the arterial wall by a gallstone. To the best of our knowledge, Mirizzi syndrome associated with pseudoaneurysm rupture is rare. Our study suggested that cholecystectomy preceded by transcatheter arterial embolization is an effective strategy to control bleeding in patients with hemobilia due to aneurysm.

Published: June 2022

Background

In treatment of neuroendocrine neoplasms (NENs), confirmation of somatostatin receptor expression with 68Ga-DOTA somatostatin analogues is mandatory to determine eligibility for peptide receptor radionuclide therapy (PRRT). [18F]DOPA can detect additional lesions compared to [68Ga]DOTA-TOC. The aim of this study was to explore differences in tumour detection of both tracers and their relevance for selecting patients for PRRT. We retrospectively studied eight patients with NENs who underwent both [68Ga]DOTA-TOC and carbidopa-enhanced [18F]DOPA PET/CT, before first-time PRRT with [177Lu]DOTA-TATE. Tracer order was influenced due to stock availability or to detect suspected metastases with a second tracer. On CT, disease control was defined as a lesion showing complete response, partial response, or stable disease, according to RECIST 1.1. criteria.

Results

Seven patients with in total 89 lesions completed four infusions of 7.4 GBq [177Lu]DOTA-TATE, one patient received only two cycles. Before treatment, [18F]DOPA PET/CT detected significantly more lesions than [68Ga]DOTA-TOC PET/CT (79 vs. 62, p < .001). After treatment, no difference in number of lesions with disease control was found for [18F]DOPA-only (5/27) and [68Ga]DOTA-TOC-only lesions (4/10, p = .25). [18F]DOPA detected more liver metastases (24/27) compared to [68Ga]DOTA-TOC (7/10, p = .006). Six patients showed inpatient heterogeneity in treatment response between [18F]DOPA-only and [68Ga]DOTA-TOC-only lesions.

Conclusions

Response to PRRT with [177Lu]DOTA-TATE was comparable for both [68Ga]DOTA-TOC- and [18F]DOPA-only NEN lesions. [18F]DOPA may be capable of predicting response to PRRT while finding more lesions compared to [68Ga]DOTA-TOC, although these additional lesions are often small of size and undetected by diagnostic CT.

PURPOSE

Seropositivity for the HPV16-E6 oncoprotein is a promising marker for early detection of oropharyngeal cancer (OPC), but the absolute risk of OPC after a positive or negative test is unknown.

METHODS

We constructed an OPC risk prediction model that integrates (1) relative odds of OPC for HPV16-E6 serostatus and cigarette smoking from the human papillomavirus (HPV) Cancer Cohort Consortium (HPVC3), (2) US population risk factor data from the National Health Interview Survey, and (3) US sex-specific population rates of OPC and mortality.

RESULTS

The nine HPVC3 cohorts included 365 participants with OPC with up to 10 years between blood draw and diagnosis and 5,794 controls. The estimated 10-year OPC risk for HPV16-E6 seropositive males at age 50 years was 17.4% (95% CI, 12.4 to 28.6) and at age 60 years was 27.1% (95% CI, 19.2 to 45.4). Corresponding 5-year risk estimates were 7.3% and 14.4%, respectively. For HPV16-E6 seropositive females, 10-year risk estimates were 3.6% (95% CI, 2.5 to 5.9) at age 50 years and 5.5% (95% CI, 3.8 to 9.2) at age 60 years and 5-year risk estimates were 1.5% and 2.7%, respectively. Over 30 years, after a seropositive result at age 50 years, an estimated 49.9% of males and 13.3% of females would develop OPC. By contrast, 10-year risks among HPV16-E6 seronegative people were very low, ranging from 0.01% to 0.25% depending on age, sex, and smoking status.

CONCLUSION

We estimate that a substantial proportion of HPV16-E6 seropositive individuals will develop OPC, with 10-year risks of 17%-27% for males and 4%-6% for females age 50-60 years in the United States. This high level of risk may warrant periodic, minimally invasive surveillance after a positive HPV16-E6 serology test, particularly for males in high-incidence regions. However, an appropriate clinical protocol for surveillance remains to be established.
Worse Tibiofemoral Cartilage Composition Is Associated with Insufficient Gait Kinetics After ACL Reconstruction

Published: June 2022

Purpose

Greater articular cartilage T1ρ magnetic resonance imaging relaxation times indicate less proteoglycan density and are linked to posttraumatic osteoarthritis development after anterior cruciate ligament reconstruction (ACLR). Although changes in T1ρ relaxation times are associated with gait biomechanics, it is unclear if excessive or insufficient knee joint loading is linked to greater T1ρ relaxation times 12 months post-ACLR. The purpose of this study was to compare external knee adduction (KAM) and flexion (KFM) moments in individuals after ACLR with high versus low tibiofemoral T1ρ relaxation profiles and uninjured controls.

Methods

Gait biomechanics were collected in 26 uninjured controls (50% females; age, 22 ± 4 yr; body mass index, 23.9 ± 2.8 kg·m−2) and 26 individuals after ACLR (50% females; age, 22 ± 4 yr; body mass index, 24.2 ± 3.5 kg·m−2) at 6 and 12 months post-ACLR. ACLR-T1ρHigh (n = 9) and ACLR-T1ρLow (n = 17) groups were created based on 12-month post-ACLR T1ρ relaxation times using a k-means cluster analysis. Functional analyses of variance were used to compare KAM and KFM.

Results

ACLR-T1ρHigh exhibited lesser KAM than ACLR-T1ρLow and uninjured controls 6 months post-ACLR. ACLR-T1ρLow exhibited greater KAM than uninjured controls 6 and 12 months post-ACLR. KAM increased in ACLR-T1ρHigh and decreased in ACLR-T1ρLow between 6 and 12 months, both groups becoming more similar to uninjured controls. There were scant differences in KFM between ACLR-T1ρHigh and ACLR-T1ρLow 6 or 12 months post-ACLR, but both groups demonstrated lesser KFM compared with uninjured controls.

Conclusions

Associations between worse T1ρ profiles and increases in KAM may be driven by the normalization of KAM in individuals who initially exhibit insufficient KAM 6 months post-ACLR.
The Relationship of Year Group and Sex on Injury Incidence and Countermovement Jump in Adolescent Ballet Dancers: A Cross-Sectional Analysis
Authors: Kolokythas Nico , Metsios George S. , Galloway Shaun M. , Allen Nick , Wyon Matthew A.
Published: June 2022

Introduction: Pre-professional ballet training involves long training hours from an early age that could influence young dancers' physical performance and injury incidence. This cross-sectional analysis investigated the relationship of year group and sex with countermovement jump and injury incidence (primary outcome) in adolescent ballet dancers at a pre-professional dance school.
 Method: Countermovement jump (CMJ) height was recorded at the start of the academic year for 179 participants (M = 68, F = 111) spread across eight year-groups. Injury etiology and incidence was prospectively recorded over a 6-month period (September through February) by the medical team using a time-loss definition.
 Results: Between-subject statistically significant differences were reported for sex [F(1, 153) = 101.46; p < 0.001], year group [F(7, 153) = 12.57; p < 0.001], and sex*year group [F(7, 153) = 9.22; p < 0.001]. Mean CMJ across the year groups ranged between 24.7 to 41.3 cm for males and 23.5 to 25.1 cm for females. Injury incidence per dancer was 0.84 (CI: 0.13, 1.56) and injury incidence per 1,000 hours of dance was 1.94 (CI: 1.63, 2.25). No statistically significant differences between sexes or year groups were reported for injury incidence per 1,000 dance hours and time-loss. Hours dancing was statistically significantly positively associated with CMJ (r = .481, p < 0.05) and negatively associated with injury incidence (r = -.253, p < 0.05) for males; for females it was positively associated with time-loss (r = .254, p < 0.05).
 Conclusion: Even though CMJ was cross-sectionally monitored, the expected increased physical abilities in males as they grew older and progressed through their training was observed. Females did not indicate a similar increase in their physical ability, but they seemed to become more susceptible to injuries as they grow older. The lack of this speculative physiological development for the females may be associated with the ballet-only approach in their training. The use of CMJ as an injury screening tool may be limited, however, it could still be used as a tool to monitor physiological and fundamental motor skill development of adolescent dancers, as jumping is an integral part of ballet.
Case Report: Open biopsy and drainage for breast abscess caused by cholesterol granuloma is beneficial rather than breast core biopsy
Authors: Halim Freda , Hanafi Ricarhdo Valentino , Wahjoepramono Eka Julianta
Published: June 2022

Cholesterol granuloma is a rare non-infectious disease. Currently, there are no established guidelines, leaving the clinician to decide the best practice for each patient. A 43-year-old woman presented to the Surgery Clinic at Siloam General Hospital, Tangerang, Banten, Indonesia, with the primary complaint of a painful mass located in her left breast over the previous week before being admitted to the hospital. The mass was found abruptly and was accompanied by severe pain and fever. On inspection, peau d’orange, nipple retraction, tenderness, and warmth of the skin were observed. Ultrasonography suggested a malignant mass. The primary diagnosis was breast cancer, with a secondary differential diagnosis of breast abscess. An open biopsy was chosen because a breast abscess was the possible diagnosis. The biopsy results showed characteristics of cholesterol granuloma. Following the operation, the pain score was notably reduced as the operation showed a satisfactory result. The primary purpose of this case report was to illustrate a case of breast abscess caused by cholesterol granuloma, in which open excisional biopsy and drainage was superior for pain reduction and faster recovery.

Published: June 2022

Middle-aged persons with multimorbidity have to take their illnesses into account in their daily work, family and leisure activities. The MuMiA project aims to identify early preventive measures that make it easier for those between 30 and 60 years of age with multiple chronic diseases to manage their illnesses in their everyday lives. An interdisciplinary workshop and interviews with multimorbid middle-aged adults and their principal healthcare providers will be used to collect information on the management of care in the contexts of patients’ daily work, family and leisure activities. Data obtained in the interviews will be coded inductively and analysed using content analysis. Workshop outputs will be transcribed and evaluated by the authors. This study has received ethical approval from the Faculty of Medicine Ethics Committee of Goethe University (2021-47). The project will generate prevention recommendations that reflect the experiences of middle-aged persons living with multimorbidity and the views of their principal healthcare providers. The findings will be disseminated via conferences and peer-reviewed publications.

Published: June 2022

Background: Angiosarcoma is a rare soft-tissue sarcoma that can arise in any soft-tissue structure or viscera. Only individual case reports and small series of gastrointestinal angiosarcoma have been reported in the literature. In this paper, we report the first African case of small intestine epithelioid angiosarcoma.

Case report: Here, we present the case of a 66-year-old man who presented with melena and anemia. Physical examination showed the presence of two subcutaneous masses on the right and left flanks. Esophagogastroduodenoscopy, duodenoscopy and jejunoscopy revealed multiple purpuric and hemorrhagic nodules and masses, some of which were bleeding. Pathological study of the ampullary formation and of a subcutaneous nodule concluded to the diagnosis of epithelioid angiosarcoma. Blood transfusions and interventional endoscopy by argan plasma coagulation were required due to a continued drop in hemoglobin. A drop in hemoglobin persisted and the patient died within 10 days.

Conclusions: Angiosarcoma has a very poor prognosis due to delayed prognosis and insufficient therapeutic management. Interventional endoscopy to control bleeding can be considered in localized forms. Chemotherapy may help to prolong survival in metastatic and disseminated angiosarcoma. Further studies should be conducted to improve the prognosis.

Background: The National Youth Service Corps programme is, among other targets, aimed at promoting national inclusiveness and tolerance in a culturally heterogeneous society. Despite the importance of this programme, little has been done to evaluate its degree of success. Where evaluations are done, they are never made public. There is a need for the NYSC programme, just like all other public programmes, to be evaluated for transparency, accountability and decision-making. From an evaluation of the three measurable objectives of the NYSC programme, this dataset bridges this gap.

Methods: This dataset was collected from Nigerian graduates that completed their national service between 2012 and 2021. The data was collected through an electronic survey posted to various online platforms hosting National Youth Service Corps (NYSC) members of the various sets and batches. The data collection aimed to evaluate the three cardinal objectives of the programme. After three years of data collection (from 2019 to 2021), responses were obtained from 19,278 participants that met the eligibility criteria. The data is an Excel (.xlsx) document with 19,278 cases and 95 variables. Descriptive statistics such as frequency counts and simple percentages were used to summarise the data. However, charts are further used to illustrate the demographic attributes of the respondents. The dataset is broad and covers all the 36 states in Nigeria plus the Federal Capital Territory.

Results: The data set has many reuse potentials because it contains information on camp activities (such as parades, military drills, redeployment, quality of food, and facilities, among others), primary assignments and community service engagements of corps members.

Conclusions: The data can offer a complete evaluation of how the (NYSC) has attained three of its four cardinal objectives. A series of relationships can further be determined and tested using inferential statistics among the variables included in the dataset.
Why is health improvement policy so difficult to secure?
Authors: Cairney Paul , St.Denny Emily , Boswell John
Published: June 2022

Many governments seek to improve the health of their populations, and some seek to reduce health inequalities. Yet, there remains a large gap between their policy statements, practices, and outcomes. It prompts perennial questions in public health research: why is this gap so large, why does it endure, and what can be done to close it? In that context, this essay uses political science and policy studies’ insights to explain the gap between rhetorical and substantive support for health improvement policies. On the one hand, the idea of ‘prevention’ has widespread appeal, particularly when governments think they can save money or reduce inequalities by preventing problems happening or worsening. While health protection inoculates populations against communicable diseases, health improvement strategies, including ‘Health in All Policies’ (HiAP), address non-communicable diseases (NCDs). Further, the coronavirus disease 2019 (COVID-19) pandemic highlighted the unequal spread of ill health, showing that preventive health ideas should be at the core of government responses. On the other hand, there is: a large gap between rhetorical commitment and actual practices, a continuous HiAP implementation gap, and a tendency for COVID-19 health protection to overshadow health improvement. Explaining each problem clearly should help public health researchers support solutions that are tethered to political reality. To that end, we identify the factors that always undermine prevention policies and those specific to HiAP and COVID-19. We go beyond a tendency to relate politics primarily to leadership or treat low ‘political will’ as the main policymaking problem. Instead, we identify the systemic policymaking dynamics that apply to even the most sincere, energetic policymakers. Health improvement policy is typically undermined by a lack of: clarity about what prevention means in practice; congruity between the radical aims of prevention and established policymaking routines and practices; and, capacity to overcome obstacles to policy change.
Integrating geospatial techniques and field survey to assess the changing nature of meander movements and meander geometry of Raidak-I River in the Himalayan foothills, West Bengal

Published: June 2022

Channel migration and resultant meander movements are the two important fluvial processes found in the riparian environment of a river basin. The present research explores the changing nature of the meander movements and meander geometry of the Raidak-I River in the Himalayan foothill region using geospatial tools. The study incorporated Landsat data (satellite imageries) for the years 1972, 1980, 1988, 2004, 2012 and 2021 and the whole study has been segmented into five periods i.e., 1972–1980, 1980–1988, 1988–2004, 2004–2012 and 2012–2021 to examine which type of meander movement dominates in the Raidak-I River within a particular time frame and how the nature of the meander movements is being changed over time. Bank lines of different periods have been superimposed with the help of the overlay analysis method in ArcGIS software (Version 10.8) to obtain the results. Furthermore, Arc-Extension tools have also been used to measure the meander geometry. Twelve active river bends have been identified to study meander geometry of sinuosity indices, meander length, meander width, meander-ratio, channel width and radius of curvature from 1972 to 2021. Initially, lateral movements predominated but, in the late-stage, rotational movement became much more prominent, which indicates dynamicity of the river channel in recent time. The cross-sectional study revealed that a convex bank has frequently been replaced with a concave bank and vice versa. The study finds human intervention – especially the construction of embankments – is the main reason behind such meander dynamics. The method we have used here is very simple, and thus can be considered for any part of the world and is very beneficial for identifying suitable sites for embankment construction, river restoration and channel management.
Guía práctica de la formación en línea

Published: June 2022

El confinamiento domiciliario derivado de la expansión del virus SARS-CoV-2 supuso realizar la Formación Universitaria de forma no presencial. Aunque para cierto porcentaje de la población universitaria supuso enfrentarse a una nueva situación, en realidad la Formación Universitaria a Distancia en España tiene más de 50 años de antigüedad. La educación a distancia es una modalidad educativa que permite que las dificultades para realizar la educación presencial (distancia, incompatibilidad de horarios, falta de espacios) no condicionen el proceso de enseñanza-aprendizaje. En este sentido, los avances tecnológicos de los medios de información y comunicación son fundamentales. En la educación a distancia, además de fomentar la interactividad del alumno, los profesores deben formarse en las técnicas y medios específicos para transmitir de la forma más adecuada los conocimientos y aprendizajes conforme a las características de cada materia. El incremento de la oferta formativa universitaria online en castellano permite ubicar a las universidades en posiciones competitivas en los países hispanoparlantes al vencer las restricciones de movilidad internacional. Así también permite incrementar la internacionalización de las universidades mediante el desarrollo de proyectos formativos en colaboración con otras universidades, tanto para la conformación del profesorado del curso, como para la captación de alumnado internacional. Esta apertura de la Universidad a la formación internacional requiere que los docentes conozcan los medios y sepan utilizar las herramientas y mecanismos que tienen a su disposición para seleccionar los más adecuados para conseguir sus objetivos formativos. Diferentes instituciones educativas han publicado documentos-guía de docencia en línea, centradas principalmente en criterios docentes. Sin embargo, esta guía aporta información práctica sobre la utilización de las herramientas de docencia en línea, enfocada principalmente al personal docente. Saber cómo utilizar las herramientas disponibles aumentará la calidad de la enseñanza y el control del docente sobre el funcionamiento de las herramientas, aportándole seguridad pedagógica.

Extreme Inflation and Time-Varying Expected Consumption Growth
Authors: Dergunov Ilya , Meinerding Christoph , Schlag Christian
Published: June 2022

In a parsimonious regime switching model, we find strong evidence that expected consumption growth varies over time. Adding inflation as a second variable, we uncover two states in which expected consumption growth is low, one with high and one with negative expected inflation. Embedded in a general equilibrium asset pricing model with learning, these dynamics replicate the observed time variation in stock return volatilities and stock-bond return correlations. They also provide an alternative derivation for a measure of time-varying disaster risk suggested by Watcher [ Wachter J (2013 ) Can time-varying risk of rare disasters explain aggregate stock market volatility? J. Finance 68(3):987–1035]. implying that both the disaster and the long-run risk paradigm can be extended toward explaining movements in the stock-bond correlation.

Temporomandibular disorders. Part 3: pain and pharmacological therapy
Authors: Clarke Peter , Oluwajana Funmi , James Martin , Crawford Charles , Foster-Thomas Emma , Allan Rigel
Published: June 2022

Temporomandibular disorders (TMD) comprise a variety of diagnoses with multifactorial aetiologies. The treatment of these conditions is often multimodal, reflecting the complex nature of their pathogenesis. Pharmacology has long been used for the control of inflammation and pain in various acute and chronic conditions. Although not the mainstay of treatment in TMD, pharmacology frequently plays a supportive role, and numerous drugs are available that act on several potential targets. This article, the third in a series of six, summarizes the pathogenesis of pain relevant to TMD, before reviewing the current medications available, their efficacy and their potential indications.

CPD/Clinical Relevance: Understanding the potential medications available can help clinicians select an appropriate drug to complement other treatment for TMD.
What you need to know about: organising pneumonia
Authors: Anandan Lavanya , Carasco Clare , Mori Letizia , Margaritopoulos Georgios A
Published: June 2022

Organising pneumonia was first described in the context of respiratory infection, but over time has become established as its own entity. It is an area of diagnostic complexity because of the non-specific presenting symptoms and signs that can often mimic other respiratory pathology. Multidisciplinary review to correlate clinical, radiological and histopathological features can aid timely and effective diagnosis. This article discusses the epidemiology, aetiology, clinical, radiological and histopathological features, investigation and management of organising pneumonia.

Published: June 2022

The article discusses the topical issue of a model of digital competencies for a future teacher. The analysis of the composition and structure of the most relevant models of digital competencies of a citizen and a modern teacher is carried out. In addition, the article reveals approaches to the formation of the content of digital competence, and provides the results of an empirical study, which consists in analyzing the results of a survey of practicing teachers and teacher-training students in order to identify the most demanded digital competencies of a future teacher. The article substantiates the authors’ content of the competence of a future teacher, a university student. The purpose of this article is to develop a theoretical model of digital competence of a future teacher, taking into account the dynamic technologisation of the modern world and the peculiarities of Russian education, based on an analysis of approaches to determining the content of its digital competencies. According to the analysis of studies, the issue of teachers’ digital competence is not sufficiently disclosed. Numerous studies on digital competencies of a person, teacher, etc. do not fully solve the problem of assessing the digital competence of future teachers.
Korean way of perceiving the determinism of French spectral music and concrete music since 1970
Authors: Jınho Kim
Published: June 2022

We studied determinism and free will, encompassing links between philosophy, psychology, musical poetics, music analysis, and musical theory of mind (MTOM). The determinism of a musical piece refers to its deterministic features, the deterministic compositional processes involved in its creation, as well as the psycho-poetical determinism of its composer. A strong deterministic composition generates multiple musical elements rigidly and automatically under the premises set by a strong poetic determinist. A weakly deterministic composition, as created by the weak poetic determinist, generates small elements somewhat automatically and logically. Poetic libertarians compose music without planning and as their fancy dictates. We use these ideal definitions to classify certain French spectral and concrete composers and their pieces. We surveyed Koreans to establish whether they heard these genres and composers as such. Five hundred four randomly selected respondents in Korea heard parts of two spectral and two concrete pieces, then completed a data collection tool. Analyzing data in SPSS/Microsoft Excel we identified how people listen to musical determinism/libertarianism and how people have MTOM depend on their psycho-social attributes, including their psychological beliefs in and understanding of determinism/libertarianism: e.g. Respondents who properly understood determinism/libertarianism did better at perceiving the deterministic spectral music and free concrete music than did individuals who did not. Our phenomenological research did not provide the only possible explanation of the links or correlations.

Abstract. Pujisiswanto H, Mar’ah DL, Sriyani N, Yusnita, Evizal R. 2022. Effectivity of soap nuts extract (Sapindus rarak) as bioherbicide toward the growth of Leptochloa chinensis and Fimbristylis milacea. Biodiversitas 23: 1222-1230. Fimbristylis miliaceae and Leptochloa chinensis weeds were grown predominantly in rice fields which cause a decrease in production yields of up to 36%-43%. The aim of this experiment was to evaluate the method of extractions and find the best concentration of Sapindus rarak by Aqueous and methanol extracts against the growth of F. miliacea and L. chinensis, which do not reduce the growth of rice. Two experiments were arranged for this research; the first was bioassay tests of weed growth of F. miliaceae and L. chinensis at the greenhouse, which were applied by aqueous and methanol S. rarak extracts. It was carried out using a randomized block design in factorial (2x5). The second experiment was the rice growth toxicity test which was applied S. rarak extracted by aqueous and methanol, analyzed to single factor randomized design with various concentrations. The results showed that the application of S. rarak extracted by aqueous and methanol was able to inhibit the growth of L. chinensis and F. mileacea weeds at a concentration of 25%, 50% and 75%. The application of S. rarak extracted by aqueous did not affect rice growth, whereas S. rarak extracted by methanol inhibited rice height and stover weight at a concentration of 75%, but did not inhibit root length growth and leaf number.

Abstract. Purwanto H, Soesilohadi RCH, Trianto M. 2022. Stingless bees from meliponiculture in South Kalimantan, Indonesia. Biodiversitas 23: 1254-1266. Kalimantan Island has many species of stingless bees that are widespread throughout the province. However, their morphology, morphometry, and nest structure characteristics have not been documented comprehensively. This paper described the morphological characters, morphometric measurements, nest entrance, and brood cell characteristics of stingless bees from meliponiculture in South Kalimantan, Indonesia. Ten stingless bee species were identified based on their morphological features: Tetragonula laeviceps (Smith, 1857), T. fuscobalteata (Cameron, 1908), T. drescheri (Schwarz, 1939), T. melanocephala (Gribodo, 1893), T. biroi (Friese, 1898), Homotrigona apicalis (Smith, 1857), H. canifrons (Smith, 1857), Heterotrigona itama (Cockerell, 1918), Geniotrigona thoracica (Smith, 1857), and Lepidotrigona terminata (Smith, 1878). Principal component analysis was performed to identify the grouping characters and thus determine their diagnostic characters. Furthermore, the shape, diameter, length, ornamentation, and color of the nest entrance and the arrangement, cells, and color of brood cells were observed. This study is the first to report high variations in the type of entrance opening and arrangement of brood cells for stingless bee species, which are abundant in South Kalimantan.

Abstract. Kusnadi A, Kurnianto D, Madduppa H, Zamani NP, Ibrahim PS, HernawanU E, Utami RT, Triandiza T. 2022. Genetic diversity and population structure of the boring giant clam (Tridacna crocea) in Kei Islands, Maluku, Indonesia. Biodiversitas 23: 1273-1282. Giant clams (Tridacninae) are ecologically important species in the coral reef ecosystems. They provide valuable functionsto traditional fisheries in Kei Islands, Maluku. However, their population isunder great pressure due to anthropogenic threats, such as overfishing and habitat degradation. To provide important data for devising effective conservation management strategies for giant clams, we investigated genetic diversity and population structure of the boring giant clams Tridacna croceain Kei Islands based on partial mitochondrial COI gene sequence. Tissue samples were collected from six sites: Kur, Dullah Laut, Tanimbar Kei, Dar, Labetawi, and Difur. We sequenced 477 base pairs of COI gene and identified 42 haplotypes and 52 polymorphic sites. Analysis of genetic diversity showed Dullah Laut and Dar had the highest genetic diversity. Population structure and genetic distance analysis showed unstructured populations with high genetic closeness among sites. This finding was also confirmed by the mixture pattern of the haplotype network. Further analysis using Bayesian models on gene flow revealed high genetic exchange among sites and that Dullah Population predominantly served as a source site for the other sites. This indicated a high probability of successful larval dispersal among sites. Based on these findings, we predict that the boring giant clams likely form a single population in Kei Islands. Our study warrants conservation priority for Dullah population as the main source of gene flow.

Abstract. Sukmawati S, Rosalina F, Sipriyadi, Dewi NK, Yunita M, Sarhan ART, Rahayu Y, Kusumawati E. 2022. Short Communication: Bacterial diversity of mangrove ecosystem in Klawalu Sorong, West Papua, Indonesia. Biodiversitas 23: 1427-1432. The mangrove ecosystem is a producer of detritus and a source of nutrients and organic matter. Some of the ecological functions of mangrove forests are coastline protector, preventing seawater intrusion, as a habitat for various living creatures, a microclimate regulator, a nursery ground, spawning ground, as well as a feeding ground for various aquatic biota. The mangrove forest ecosystem cannot be separated from the role of microbes in helping the process of soil biochemical cycles. In the biochemical cycle, microbes are able to maintain the availability of macronutrients in the soil. The objective of this study was to identify the diversity of bacteria in the mangrove ecosystem in Klawalu, Sorong City. The research method descriptively described the diversity of bacterial species found in the mangrove ecosystem in Klawalu, Sorong City, West Papua Province. The results indicated that the DNA fragments of the four isolates obtained from this study were around 1300 bp. Meanwhile, the bacterial species obtained were isolated SA3, identified as Bacillus safensis strain C251, isolate SA8 identified as Bacillus amyloliquefaciens strain NO10, isolate SL8 was identified as Clostridium sp. JC336, and isolate SL1 was identified as Bacillus australimaris strain IIHR GAPB01.

Abstract. Rohman F, Priambodo B, Akhsani F, Rahayu SE, Wangkulang S, Kundariati M. 2022. Revealing herpetofauna diversity at Brantas River, East Java, Indonesia: Evidence of decreasing populations. Biodiversitas 23: 1475-1481. Conservation planning is very important to preserve nature and ecosystems. Based on this, exploration and species inventory in nature need to be carried out. Group of animals that have an important role in the environment is herpetofauna. This study aims to reveal the abundance, evenness, and richness of herpetofauna in Brantas River's streams connection. This study uses the Visual Encounter Surveys (VES) sampling method at 8 points located in Blitar, Tulungagung, Malang, Mojokerto, Kediri, and Batu City, East Java, Indonesia. The results showed that the diversity index (H') 1 < 2, 3959 < 3, with the criteria for the diversity index being moderate. The value of e is 0.74 > 0.6, which means high species uniformity. Specific richness has a value of 4.53 which means in the moderate category. There were 12 species of amphibians and 14 reptile species. Five species are of low-risk status with decreasing population in nature and two species is of vulnerable status. Species in the declining category are Odorrana hosii, Limnonectes microdiscus Wijayarana masonii, Leptobrachium hasseltii, and Philautus aurifasciatus. Species in the vulnerable category are Microhyla orientalis and Gonocephalus kuhlii. Species in the declining category require attention from conservation efforts because their presence is important in various aspects of the ecosystem, such as the food chain, bioindicators, and natural enemies.

Abstract. Kurniawan ID, Rahmadi C, Akbar RTM, Prakarsa TBP. 2022. Stygobiotic isopod Stenasellus sp. in Sarongge Jompong cave, Tasikmalaya karst area, Indonesia. Biodiversitas 23: 1495-1504. Stenasellus, a stygobiotic isopod, was first reported in Tasikmalaya karst by local cavers in 2018 in Sarongge Jompong Cave. This study aimed to investigate the population, activities, and habitat characteristics of Stenasellus sp. in Sarongge Jompong, Tasikmalaya karst area, Indonesia. Population and activities were recorded through direct intuitive search. We measured several important physicochemical parameters to study habitat characteristics. Statistical analyses-namely Non-metric Multi-dimensional Scaling and Detrended Correspondence Analysis-were conducted to understand the difference in water characteristics among microhabitats and the relation between water characteristics and population size. The results showed that the population was distributed in 4 microhabitats with the maximum observed individuals of 8. Several activities were successfully monitored, including crawling, resting, hiding in crevices, and moving to different locations through the water. All microhabitats were wet gours connected to small water currents located in the dark zone of the cave passage. Water characteristics of microhabitat site 1 were more similar to site 2 and the numbers of individuals in these sites were larger than sites 3 and 4. Among water parameters, resistivity showed the most robust relation with Stenasellus population in which both variables were positively correlated. This correlation indicated that Stenasellus sp. preferred microhabitats with less contamination. Intrinsic and extrinsic factors may potentially threaten the population. The potential threats and conservation challenges need to be identified and mitigated to reduce the risk of biodiversity loss to these isopods, mainly due to their small population size, specific microhabitat, and susceptibility to disturbance. Considering these factors, research on taxonomy will be essential for conservation efforts.
