Authors: Rosenau Lorenz , Gruendner Julian , Kiel Alexander , Köhler Thomas , Schaffer Bastian , Majeed Raphael
Published: March 2024

BACKGROUND

To advance research with clinical data, it is essential to provide researchers with fast and easy access to the available data, which is especially challenging for data from different source systems within and across institutions. Over the years, many research repositories and data standards have been created. One of these is the FHIR standard, used by the German Medical Informatics Initiative (MII) to harmonize and standardize data across university hospitals in Germany. One of the first steps to make this data available is to allow researchers to create feasibility queries to determine the data availability for a specific study. Given the heterogeneity of different query languages to access different data across and even within standards such as FHIR (e.g., CQL and FHIR Search), creating an intermediate query syntax for feasibility queries reduces the complexity of query translation and improves interoperability across different research repositories and query languages.

OBJECTIVE

This study describes the creation and implementation of an intermediate query syntax for feasibility queries and how it integrates into the federated German health research portal (Forschungsdatenportal Gesundheit) and the German medical informatics initiative.

METHODS

We analyzed the requirements for feasibility queries, and the currently available feasibility tools that research repositories offer. Based on this analysis, we developed an intermediate query syntax that can be easily translated into different research repository-specific query languages.

RESULTS

The resulting Clinical Cohort Definition Language (CCDL) for feasibility queries combines inclusion criteria in a conjunctive normal form and exclusion criteria in a disjunctive normal form, allowing for additional filters like time or numerical restrictions. The inclusion and exclusion results are combined via an AND NOT expression to specify complex feasibility queries. We defined a JSON schema for the CCDL, generated an ontology, and demonstrated the use and translatability of the CCDL across multiple studies and real-world use cases.

CONCLUSIONS

We developed and evaluated a structured query syntax for feasibility queries and demonstrated its use in a real-world example as part of a research platform across 39 German university hospitals.

Published: March 2024

BACKGROUND

Functional abdominal pain disorders (FAPDs) are common in young people and are characterized by persistent or recurrent abdominal symptoms without apparent structural or biochemical abnormalities. FAPDs are associated with diminished quality of life, school absence, increased health care use, and comorbid anxiety and depression. Exposure-based internet-delivered cognitive behavioral therapy (ICBT) has demonstrated efficacy in alleviating abdominal symptoms and improving quality of life. However, a deeper understanding of effect mechanisms and identification of possible additional treatment targets could refine treatment.

OBJECTIVE

This protocol paper aims to describe a study focusing on children and adolescents undergoing ICBT for FAPDs, aiming to further investigate the underlying mechanisms of effect.

METHODS

Children (8-12 years), adolescents (13-17 years) with FAPDs, and their respective parents will be included for 10 weeks for ICBT. First, detailed trajectories of effect are examined through a randomized single-case design study involving 6 children and 6 adolescents (substudy 1). Following this, an open-ended explorative pilot study with 30 children and 30 adolescents explores potential illness-related cognitive biases and interoceptive accuracy before and after treatment (substudy 2). Finally, spanning across these 2 substudies, including all parents from substudies 1 and 2, we will assess parental distress and illness worries before and after treatment, and how these factors impact the treatment adherence and outcomes of the child or adolescent (substudy 3).

RESULTS

Recruitment of participants began in June 2022 and is finalized for substudy 1 and ongoing for substudies 2 and 3. Recruitment is expected to be completed by January 2025, with final data collection during April 2025.

CONCLUSIONS

The findings have the potential to contribute to the ongoing improvement of specialized psychological treatment for FAPDs in young people.

Improving Access to and Delivery of Maternal Healthcare Services to Prevent Postpartum Haemorrhage: A Human-Centred Design Approach (Preprint)
Authors: Aigbogun Jr Eric
Published: March 2024

BACKGROUND

A significant cause of postpartum haemorrhage (PPH) is access to and delivery of maternal healthcare services. Several multi-sectoral strategies have been deployed to address the challenges with little success; thereby necessitating the use of HCD to enhance healthcare delivery, particularly in PPH management.

OBJECTIVE

Develop facility-level solutions for optimising uterotonic supply chain systems and health service delivery in the management of postpartum haemorrhage (PPH) through a Human-Centred Design (HCD) approach in selected Nigerian states.

METHODS

The research employed a four-phase HCD methodology: 1) co-research, 2) co-design, 3) co-refinement, and 4) implementation. However, this paper focuses on the first three phases. In the co-research phase, 221 interviews were conducted, involving pregnant women, healthcare workers, and key stakeholders. Additionally, 33 sites were observed across a three-level continuum of care. Interviews and focus group discussions revealed insights into the distribution of human health workers, PPH cases observed, knowledge of uterotonic use, and steps to administer uterotonics. Finally, 150 ideas were produced and translated into twelve solution prototypes in the co-design phase.

RESULTS

Progressive refinement following feedback from 140 stakeholders led to the selection of three final solutions: 1) implementing equitable telemedicine to improve the distribution of HRH to reduce waiting time and improve the quality of service, 2) increasing demand for ANC services among pregnant women and their families, and 3) delivering a comprehensive uterotonics logistics management program for stream-lined storage and management of uterotonics.

CONCLUSIONS

This approach aligns with global health trends advocating for HCD integration in healthcare programming and aims to empower local champions to drive sustainable improvements in maternal health outcomes. If the developed prototypes are judiciously implemented across the states, they can strengthen clinical care and reduce gaps in maternal health service delivery.

Published: March 2024

Abstract: Soil Moisture is directly related to the amount of irrigation in agriculture and influences the yield of crops. Accordingly, a soil moisture sensor is an important tool for measuring soil moisture content. In this study, the previous research conducted in recent 2-3 decades on soil moisture sensors was reviewed and the principles of commonly used soil moisture sensors and their various applications were summarized. Furthermore, the advantages, disadvantages, and influencing factors of various measurement methods employed were compared and analyzed. The improvements presented by several scholars have established the major applications and performance levels of soil moisture sensors, thereby setting the course for future development. These studies indicated that soil moisture sensors in the future should be developed to achieve high-precision, lowcost, non-destructive, automated, and highly integrated systems. Also, it was indicated that future studies should involve the development of specialized sensors for different applications and scenarios. This review research aimed to provide a certain reference for application departments and scientific researchers in the process of selecting soil moisture sensor products and measuring soil moisture.

Published: March 2024

Abstract: Now-a-days it is necessary to utilize the wastes effectively with technical development in each field. The old abandoned tyres from cars, trucks, farm and construction equipment and off road vehicles are stockpiled throughout the country. This leads to various environmental problems which include air pollution associated with open burning of tyres and other harmful contaminants like (polycyclic aromatic hydrocarbon, dioxin, furans and oxides of nitrogen) and aesthetic pollution. They are non biodegradable; The waste rubber tyre has become a problem of disposal. Due to increase in demand of automobiles in our daily lives, rubber tyre waste is also increasing simultaneously which results in disposal of rubber waste in landfill. The rubber takes more time to decompose and also leads to land pollution. So in this project the waste rubber can be reused in road construction works by partially replacing with coarse aggregate with bitumen in percentage (5, 10, 15, 20, 25 and 30) and carried out different test result based on it. This is not only to minimize the pollution occurred due to waste tyres but also minimizes the use of conventional aggregate which is available in exhaustible quantity. The addition of rubber tyre in flexible pavements enhances the properties of road surfaces as well as it reduces the rubber tyre waste from the land and decreases the self-weight of the bitumen mix.

Published: March 2024

Objectives The purspose of this study is to analyze the effect of cosmetics National Competency Standards recognition on cosmetics subject necessity and subject satisfaction through field usability.
Methods A survey was conducted on 304 cosmetologists who had experience in cosmetic course. To verify the research hypothesis, the structural equation model was establised and analyzed using AMOS, and bootstrapping was used to verify the mediation effect. The significance of the mediation effect was verified again through the Sobel Test.
Results Recognition of cosmetics NCS had a positive (+) effect on field usability. Field usability had a positive (+) significant effect on the cosmetics subject necessity and had a positive (+) effect on cosmetics subject satisfaction. It was confirmed that the recognition of cosmetics NCS did not have a direct effect on the cosmetics subject necessity, and only the indirect path was significant, confirming that field usability had a complete mediation effect. In the relationship between whether it is an cosmetics NCS recognition, field usability, and cosmetics sbject satisfaction, the indirect path generates a standardized path coefficient that greatly exceeds 1.0, and the direct path was an inconsistent mediation effect with opposite sign values, confirming that the direct path had a spurious effect. This means that in the relationship between cosmetics NCS recognition and cosmetics subject satisfaction, field usability has a complete mediation effect.
Conclusions Cosmetics NCS recognition does not have a direct effect on the necessity of cosmetics subject and satisfaction of cosmetics subject, but field usability plays a complete mediation role and has an effect. This can be said to be a result that corresponds to the characteristics of the practical-oriented beauty occupation. The cosmetics NCS should be reorganized according to the beauty occupations so that cosmetics can be used more safely and appropriately in the field of beauty work by major that utilizes cosmetics.

Learning independence is a learning activity from individuals not to depend and rely on others to achieve the goals of learning, besides that learning independence is also one of the factors of successful learning achievement that will be obtained by students. This confirms that appropriate media are needed to support students in increasing their learning independence. The method used in the research is Research and Development (R&D) which aims to develop a product in the form of a learning independence poster. The research results obtained are the product in the form of a learning independence poster that must be revised before being used where the content feasibility aspect gets a good assessment with a decent category, the presentation aspect has points that must be corrected because it gets an inappropriate assessment, while the language aspect gets an assessment in a decent category. That way the product in the form of a learning independence poster can be used as a medium in helping students develop learning independence with notes that must be revised first.

Authors: Shang Jingqi , Wu Wei , He Yongqi , Lin Ronggang
Published: March 2024

The polyamide 6 powder was prepared by the liquid phase method, and then
mixed with hexagonal boron nitride (h-BN) in a high-pressure homogenizer
for micron-level mixing, and finally the composite material is obtained
by hot pressing. The thermal conductivity of composites was as high as
1.73 W/(m•K). The results showed that the dispersion of h-BN in the
matrix was well and there was no obvious agglomeration in the composite
from the scanning electron microscope. Differential scanning calorimetry
and X-ray diffraction results showed that h-BN affects the crystalline
of polyamide 6 and the thermal stability of the composites was improved.
The composite is expected to be used in high thermal conductivity
functional plastics.
Deep Learning for Optimal Phase-Shift and Beamforming Based on Individual and Cascaded Channels Estimation in the RIS-MIMO System
Authors: hussein walaa , Noordin Nor , A.Rasid Mohd , Ismail Alyani , Kareem kamil , Flah Aymen
Published: March 2024

Reconfigurable Intelligent Surfaces (RIS) represent an advanced
technology reshaping wireless communication networks. Through
intelligent configuration of wireless propagation environments using
both cost-effective passive and active elements, RIS has the potential
to bring about considerable performance improvements. In RIS-MIMO
systems, precise control of passive RIS elements is crucial in
optimizing reflected signal phases. This control necessitates intricate
algorithms, given that inaccurate phase optimization can result in
suboptimal signal focus and decreased data transmission accuracy.
Obtaining accurate channel state information (CSI) is vital for
achieving optimal phase control and high data rates; however, estimating
channels between the transmitter, RIS, and receiver poses challenges.
This paper investigates deep learning methodologies for channel
estimation, explicitly addressing the distinctive challenges associated
with phase shifts and beamforming. We present tailored deep-learning
algorithms for each estimation technique, showcasing notable
improvements in estimation accuracy, computational efficiency, and
adaptability in dynamic environments.
The developing flood rich period: science evidence and policy evolution for England. Is it time for place-based socio-ecological solutions?
Authors: Newson Malcolm , Lewin John
Published: March 2024

Flood-related policies for England are reviewed, updating needs in the
light of recent flood-rich decades and in recognition of future climate
trends. This review updates one we published in 2021- a significant year
for extreme floods in Europe that were part of a continuing trend;
governments now require fast-track adaptation and resilience policies.
Currently, the event signals of increasing spatial and temporal
variability in impacts is insufficiently incorporated in hazard/risk
assessments. We advocate a transformative policy change towards
place-based strategies, based on the fast-emerging evidence from three
sciences: hydroclimatology, hydrology and hydromorphology. It is vital
that policy actions recognise factors such as atmospheric rivers,
surface water flooding, and the role of eroded and transported sediments
in localised hazards and risks. Located vulnerabilities require local
strategies. Attribution of extreme events to climate change, and the
recognition and specification of genuinely vulnerable sites, need
further refinement and extension into public decision making. Risk
assessment needs reform, both from science but also for institutions and
individuals, with accompanying reform of flood risk management
expenditure. Data analysis, e.g. of rainfall and river flow, needs more
disciplined clarity; standard sets are needed together with their
variable spatial/temporal application. We further recognise sediment
hazards (and other entrained debris spread in flood flows) as new and
important components for the located risk of present and emerging ‘hot
spots’.

Published: March 2024

The coastal zone of West Africa covered by the State of marine protected areas (EdAMP - État des aires marines protégées d’Afrique de l’Ouest) extends approximately 6,000 km, from Mauritania in the north, passing through the deeply indented coasts of the islands and estuaries, then the lagoon coasts and the coastal strips of the Gulf of Guinea, up to Nigeria. The small island state of the Cabo Verde Islands, volcanic and mountainous, completes this geography. These coastal areas are characterized by globally significant biodiversity. EdAMP takes stock of the situation, while offering in-depth analyses as well as recommendations on the opportunities and challenges in terms of MPAs in the region.
Enhancing Digital Elevation Model Accuracy for Flood Modelling – A Case Study of the Ciberes River in Cirebon Indonesia
Authors: Sahid
Published: March 2024

Topographic conditions represented by the Digital Elevation Model (DEM) are essential in flood inundation models. The DEM which is categorised as a Digital Surface Model (DSM) stores the height information, be-sides the ground and non-ground elevation required for preprocessing before being employed in hydrologic applications, particularly in relation to flood modelling by removing non-ground elevation along the flood plain and river channels. The improvement in the accuracy of flood inundation modelling is crucial in reduc-ing the impact of flood disasters. This study aims to compare the accuracy level of the DEM based on Ter-raSAR-X data with the filtering process using slope-based filtering and combining the cross-sectional river profile from the field measurement to the filtered DEM. The result confirms that the accuracy of the DEM product is improved via filtering to remove non-ground elevations and a significant improvement in accuracy by means of fused river profile information to filtered DEM. The results of adding river information to the DEM could provide a representation closer to the cross-sectional profile of the river based on field measure-ments within the accuracy level Mean Absolute Error 2.51 m, 2.72 m and 1.91 m in the left overbank, right overbank and centre of the river, respectively. The performance results of the 2-dimensional flood hydrody-namic modelling using HEC-RAS derived from the DEM before filtering, after filtering, and the addition of river information show increasing accuracy in flood depth at each stage of the DEM processing. There is an improvement in accuracy in flood depth of approximately 11.67% using the filtered DEM, besides an in-crease in accuracy in flood depth by 24.98% utilising the filtered DEM with added river channel information.

This study examines the response to and support of the UNESCO recommendations on behalf of geo-tourism using the actual perspectives of tourists visiting the Toba region. The study employed a detailed map of Toba Geo-tourism in the Sumatra Utara Province, Indonesia, so as to provide a comprehensive understanding. The research was underpinned by a random sampling approach, gathering responses from a broad spectrum of tourists. The results captured an optimistic landscape, demonstrating a clear synergy between the UNESCO recommendations and the sentiments of the tourists. Not only did the guidelines resonate, but there was also a palpable feeling among tourists to either extend their stay or make a subsequent visit, provided the recommendations were implemented holistically. This study stresses the value of adopting and localising global sustainable tourism standards to suit a region such as Toba's unique attributes and tourist expectations. By means of this research, we aim to amplify that dialogue, charting a path for Toba and similar regions to embrace a future that is both ecologically sensitive and visitor centric.

Authors: Alikhanov Bokhir , Pulatov Bakhtiyor , Samiev Luqmon
Published: March 2024

This paper presents a comprehensive study relating to the vegetation cover change in Ugam Chatkal National Park (Uzbekistan) and its relation to climate change during the post-Soviet period (1991-2022). The study utilises remote sensing technology, specifically the Normalised Difference Vegetation Index (NDVI) and the Soil-Adjusted Vegetation Index (SAVI), to monitor spatio-temporal changes in vegetation. Landsat satellite imagery and meteorological data, including temperature and precipitation records form the basis of the analysis. The research aims to understand the impact of climatic factors, such as air temperature, soil temperature and precipitation on vegetation cover. Statistical methods, for example Pearson’s correlation analysis are employed to determine the strength and direction of relationships between these variables. The study reveals that both NDVI and SAVI are strongly correlated with air and soil temperatures, indicating the significant influence of these climatic factors on vegetation health and growth. The findings suggest that changes in vegetation cover in the Ugam Chatkal National Park are closely tied to climate change, with air temperature revealing a substantial correlation with time, indicating a trend towards increasing temperatures. The study also forecasts future climatic and vegetation trends, predicting an increase in air temperature, precipitation and vegetation cover over the next four decades. In particular, the research highlights the magnitude of monitoring and understanding the complex interactions between climate change and vegetation dynamics, which are crucial for environmental management and policy-making in the region.

Authors: Portela Gisele , Iraporda Carolina , Silvestro Luciana B. , Wagner Claudia Cecilia , Tironi Alejandra
Published: March 2024

El proceso de adsorción utilizando arcillas naturales y calcinadas como adsorbentes, se ha convertido en uno de los métodos preferidos para la eliminación de contaminantes tóxicos del agua, ya que se ha encontrado que es muy efectivo, económico, versátil y simple, resultando necesario evaluar su disposición final, como por ejemplo en matrices cementíceas o calcáreas. Por otra parte, los metales pesados son potencialmente fungistáticos, por lo que resulta de interés evaluar cómo se modifica la susceptibilidad al crecimiento fúngico en las matrices calcáreas elaboradas con arcillas calcinadas con cadmio adsorbido. El objetivo de este trabajo es estudiar la disposición final de arcillas calcinadas utilizadas para la adsorción de Cd(II), en pastas de cal hidráulica, evaluando la funcionalidad del Cd(II) adsorbido como componente retardador del desarrollo de cepas fúngicas de los géneros Aspergillus y Cladosporium. Se elaboraron pastas utilizando cal hidráulica y arcillas calcinadas con y sin cadmio adsorbido. Las pastas se mantuvieron durante 1 mes en cámara húmeda y luego 1 mes en un ambiente protegido de la lluvia. Se determinaron para todas las pastas las fases mediante difracción de rayos X y espectroscopia infrarroja con transformada de Fourier. Se determinó la cantidad de Cd(II) lixiviado utilizando espectroscopia de absorción atómica y se evaluó el crecimiento fúngico de las cepas de Aspergillus sp. y Cladosporium cladosporioides. Se concluyó que las pastas de cal hidráulica son una buena matriz para la contención de arcillas calcinadas con Cd(II) adsorbido sin alterar las fases obtenidas durante los procesos de hidratación-carbonatación y sin lixiviar el Cd(II). Se observó un retardo en el desarrollo de Aspergillus y Cladosporium sobre las superficies de las pastas conteniendo illita calcinada e illita calcinada con cadmio adsorbido.

Las arcillas se han utilizado ampliamente para remediación de aguas residuales contaminadas con metales pesados. El objetivo del presente trabajo es evaluar los cambios en la adsorción de Cd(II), cuando se utilizan arcillas naturales y calcinadas. Se seleccionaron cuatro muestras de arcillas procedentes de diferentes regiones de Argentina con mediano contenido de mineral arcilloso: illita (I), montmorillonita (M), caolinita con estructura ordenada (CO) y caolinita con estructura desordenada (CD). Se caracterizaron con Difracción de Rayos X, por Espectroscopia Infrarroja con Transformada de Fourier y superficie específica BET. Se llevaron adelante estudios de adsorción de Cd(II) con las mismas en su forma natural y calcinada, variando la concentración inicial del ión metálico. Se encontró que la arcilla natural con mediano contenido de montmorillonita y la arcilla calcinada con mediano contenido de illita (IC) presentaron los mayores porcentajes de adsorción (M 95%, IC 76%). Se concluye que el tratamiento térmico permite potenciar el uso de una arcilla (I) de la región de influencia de la Universidad Nacional del Centro de la Provincia de Buenos Aires (UNCPBA).
Aproximación a las formas cerámicas del sitio arqueológico Los Tres Ombúes (Partido de Punta Indio, Provincia de Buenos Aires) mediante la reconstrucción virtual
Authors: Ghiani Echenique Naiquen , Coronel Víctor
Published: March 2024

El sitio arqueológico Los Tres Ombúes (partido de Punta Indio, provincia de Buenos Aires) fue habitado por grupos cazadores-recolectores y ceramistas hace aproximadamente 1.000 años. Gran parte de las evidencias recuperadas corresponden a fragmentos cerámicos. El objetivo de este trabajo es caracterizar la morfología de las piezas representadas en Los Tres Ombúes mediante la reconstrucción virtual, para profundizar el conocimiento de la tecnología alfarera de los grupos humanos que habitaron el litoral rioplatense. Con tal fin fueron seleccionados tres fragmentos y tres unidades de remontaje correspondientes a seis vasijas diferentes, por presentar características propicias para la evaluación morfológica: una porción del labio que posibilite la medición del diámetro de boca y una representación del perfil que permita estimar la altura de la pieza mediante su proyección hacia el centro de la base (eje central). Para cada vasija se realizó una representación gráfica 2D a partir de fotografías a escala del perfil, con adición de las mencionadas proyecciones. Posteriormente, el dibujo fue replicado en Blender, donde la conversión a una malla tridimensional en la misma escala permitió generar el objeto 3D. La observación de las características morfológicas de las piezas permitió identificar formas mayormente no restringidas de contorno simple, mientras que el perfil restante evidencia una forma restringida simple dependiente con igual tipo de contorno. Estas corresponden a las categorías morfológicas de cuenco (n=3), escudilla (n=2) y vaso (n=1). También para cada caso se realizaron los cálculos de la capacidad o volumen bruto y de la masa del recipiente vacío. La reconstrucción virtual de las seis piezas representadas en el registro cerámico del sitio Los Tres Ombúes permitió explorar las características morfológicas y aportar a su percepción visual, lo cual implica un amplio potencial para la comunicación científica. Asimismo, los cálculos posibilitados por el programa aportaron datos significativos tendientes a la interpretación funcional del conjunto cerámico.

Published: March 2024

La importancia de la caolinita en el desarrollo de la ciencia cerámica moderna se puede apreciar al observar su amplia influencia en la cerámica, la ciencia de los materiales y la mineralogía. Dado que, en general, su uso en la industria requiere de tratamientos térmicos, resulta de interés comprender la formación del metacaolín durante la activación térmica de esta arcilla y desentrañar los mecanismos físicos y químicos involucrados en su producción. En este trabajo se estudia el inicio del proceso de deshidroxilación utilizando métodos de cálculo basados en la Teoría de la Funcional Densidad. En particular, se proponen cuatro sistemas que combinan vacancias de un grupo OH y un átomo H de la celda unidad de la caolinita. Para cada una de estas variantes se optimizó la estructura, y se analizó la energía del sistema luego de la optimización. Los resultados fueron comparados entre sí y con la literatura. Por último, para el caso más compatible con el inicio del proceso físico de deshidroxilación se estudió la densidad de estados electrónicos y se la comparó con la correspondiente a la caolinita. Los resultados obtenidos contribuyen a indagar entre distintos sistemas modelo que podrían describir el inicio del proceso de producción del metacaolín, como así también a entender las diferencias existentes entre los mismos.
Anti-doping and National Politics: An Ethnography in Brazilian Anti-doping Around the Era of the Rio de Janeiro Games
Authors: Vasques Daniel Giordani , Zuzuarregi Ekain Zubizarreta , Myskiw Mauro , Stigger Marco Paulo
Published: March 2024

This study is based on an investigation into the Brazilian anti-doping policy, with a specific focus on the establishment and operational mechanisms of the Brazilian Doping Control Authority (ABCD), under the auspices of the Ministry of Sport (ME). The objective was to describe how Brazilian national policy (general political decisions, interests of parties or particular politicians/agents) affects the fight against doping and, vice versa, how the harmonization process controlled by the World Anti-Doping Agency (WADA) affects national sports policy. A multi-sited ethnographic study was undertaken, involving field diary practices, interviews and document analysis. Adopting the perspective of pragmatic sociology, this study delves into the descriptions of three key periods in the recent history of anti-doping in Brazil: the creation of ABCD and the dissolution of ANAD (National Anti-Doping Agency), the realization of the first 100 anti-doping tests by the ABCD (critical period for its members who managed to keep away ex-officers from ANAD) and the impeachment of the Brazilian president in 2016 (ex-officers from ANAD took over the direction of the ABCD). Our analysis allowed us to conclude that ‘diverting others from decision-making spheres’ comprised a political strategy to occupy spaces of power or to stabilize itself in them, which, in this case, allowed the control of anti-doping actions in the country. Local protagonists tried to make use of international injunctions and pressure or local political events to achieve these goals.
Der ewige Verschwinder - Eine Kulturgeschichte des Flohs
Authors: Stadler Ulrich
Published: March 2024

Unter den Parasiten hat der Floh eine Sonderstellung: Anders als die Laus, die Wanze, die Zecke und die Stechmücke wird er höchst ambivalent wahrgenommen. Nur dieses Tier hat solche Hasstiraden und solche Liebeserklärungen ausgelöst; kein anderes hat die erotische Fantasie der Männer dermaßen angefacht und aufgewühlt wie der Floh. Keines ist so bewundert, so hingebungsvoll mikroskopiert und dabei so erbarmungslos malträtiert worden. Wegen seiner Winzigkeit ist der Floh für allerhand metaphorische Zwecke in den Dienst genommen worden.
Dieses Buch wirft einen genauen Blick auf den Floh und erkundet die intimen Beziehungen zwischen Menschen und Flöhen. Die untersuchten Texte und Bilder geben überraschende Auskünfte über den Menschen, sein sexuelles Verhalten, sein Verhältnis zur Natur und sein Selbstverständnis als soziales Lebewesen.

Intisari— UMKM bidang makanan dan minuman memberikan kontribusi yang signifikan terhadap perekonomian nasional sebesar 7,02%. Salah satu jenis makanan dengan prospek pasar yang sangat baik adalah produk olahan jamur krispi. Namun terdapat tantangan dalam proses pengolahan dan distribusi produk yang mempengaruhi rendahnya daya saing UMKM Jamur Krispi, maka dibutuhkanlah peningkatan kinerja supply chain dalam mengolah produk dan memenuhi permintaan konsumen. Penelitian ini bertujuan untuk mengukur dan mengevaluasi kinerja Supply Chain Management (SCM) pada UMKM Jamur Krispi agar perbaikan dengan strategi baru dapat dilakukan. Proses pengukuran performa rantai pasok menggunakan metode Supply Chain Operations Reference (SCOR) sebagai model konseptual yang dapat menjabarkan rantai pasok menjadi metrik agar didapatkan manajemen rantai pasok yang lebih efisien. Bobot performa dari setiap indikator akan dihitung menggunakan Analytical Hierarchy Process (AHP) berdasarkan jawaban kuesioner perbandingan berpasangan dari pemilik UMKM yang dianalisis. Hasil penelitian ini diperoleh 23 indikator dari lima proses yaitu plan, make, source, delivery, dan return, dengan nilai akhir kinerja SCM sebesar 80,891 dan tergolong baik. Proses inti yang memiliki nilai kinerja rendah adalah plan dan return yang masing-masing sebesar 8.098 dan 9.049.

Abstract— MSMEs in the food and beverage sector significantly contribute to the national economy of 7,02%. One type of food with excellent market prospects is processed crispy mushroom products. However, there are challenges in the process of making and distributing the product that affects the low competitiveness of the Crispy Mushroom SME; thus, an increase in supply chain management performance is needed in processing the product and meeting customer demand. This study aims to measure and evaluate the performance of Supply Chain Management (SCM) in the SME of Crispy Mushroom for improvements with new strategies that can be carried out. The process of measuring SCM performance uses the Supply Chain Operations Reference (SCOR) method as a conceptual model that can describe the supply chain into metrics for obtaining more efficient supply chain management. The performance weight of each indicator will be calculated using Analytical Hierarchy Process (AHP) based on the answers to questionnaires from the analyzed business owner. The results of this study obtained 23 indicators from five processes, namely plan, make, source, delivery, and return, with the final value of SCM performance being good. With the absolute value of SCM performance of 80.891 and classified as good. The core processes with low-performance values are plan and return, which are 8,098 and 9,049, respectively.

Research on the impact of the COVID-19 pandemic on human activities has produced many new findings. This research is built on the basis of changes in the culture of student activities, which are mostly carried out offline towards a new culture in online activities. This study examines the changes in the types of activities, the place of activities and the pattern of student activities. Through quantitative research methods, data acquisition through questionnaires and descriptive analysis, found that students' weekly activities during the pandemic were quite tiring due to the increase in the number of activities. In addition, the student activities outside the campus are not effective in supporting their weekly activities as students. This is partly because of feeling bored and disturbed by other activities. Then there was a polarization of student activities during the pandemic, which can increase activity includes: sports, independent learning, running hobbies, and taking care of the house, and several decrease activities namely:  socializing, performing arts, taking care of themselves, resting, watching, medical treatment, and weekly worship. This research can contribute to finding out the learning problems of students in their hometowns during the pandemic.
NATURAL LIGHTING’S CONTOUR, CASE: CLASSROOM-STUDIO, FLOOR 6th BUILDING C, UNIVERSITAS TRISAKTI

The room requires specific lighting according to its function. One way to achieve the room's optimal comfort is to adjust the natural or artificial lighting to the required standards. This research aims to study daylight intensity in the architectural classroom studio on the sixth floor of Building C Universitas Trisakti and compare it with the illuminance level requirements stipulated in SNI 6197: 2011. This study hypothesizes that the natural intensity of the room, which also functions as an architectural drawing studio, is incompatible with conventional lectures. The measuring instrument was the Lutron LM 8000A Light Lux Meter, while the natural lighting contour simulation used Dialux Evo 9. The results show that the measured natural lighting intensity is unevenly distributed. There are bright zones in the room that exceed the standard value of the illuminance level (> 350-750 lux) and dark zones that are below the standard of illuminance (<350-750 lux), with a distance of 0.5 m - 3m from a row of window openings as a source of lighting.

The development of construction project in Indonesia is growing rapidly. In the process of building construction projects, the phenomenon of the greenhouse effect  has been taken part. Carbon emissions are one of the results of the greenhouse effect in the process of building construction projects. The foundation is one of the most important parts of construction that serves to hold the load and as a load distributor from the construction above the ground. In foundation work using reinforced concrete structures, reinforced concrete structures are a source of carbon emissions in construction projects. This study aims  to find out how much carbon emissions are produced in the drilled pile work at the GBK Multifunctional Indoor Stadium project and which element produces the largest carbon emissions. The results of this study are carbon emissions produced by one bore pile with a diameter of 800 mm of 6553,78 kg.CO2 and the work of the bore pile, which produces the greatest carbon emissions, is material consumption of 6134.40 kg, CO2.

The type of activity, room area, and light intensity influence the visual comfort level of room users. In educational buildings, visual comfort influences the level of performance during the teaching and learning process of students. Students of the Bachelor of Architecture Study Program, FTSP, Trisakti University, use the Studio on the 6th floor (C.608-609) with 85% curtained glass window walls on the North and West, and 10% uncurtained bouvenlight windows on the South. It is estimated that the availability of natural light sources with such capacity is sufficient for the Studio learning process, but in fact users still turn on artificial lighting when working during the day. The hope is that by using curtained windows, students can regulate natural lighting needs to reduce the use of artificial lighting. Until this research was conducted, it was not known how high curtains met visual comfort standards. This research aims to create contour simulation of room’s natural light intensity C.608-609 using dialux kw06-288 software, in relation to adjust of curtains on windows with heights of 30 cm, 60 cm, 90 cm and 120 cm, and their impact on the user's feelings of visual comfort or discomfort. The results show that the distribution of natural light entering the room is not even and varied. According to SNI 03-6575-2001, the light intensity for a studio is 500-750 lux, but the measurement results show that at a curtain opening height of 120 cm, the light reach to the room with the furthest depth of 16.8m is not reached, so to achieve visual comfort the assistance of artificial lighting is needed, especially in the east-south of studio. Meanwhile, the area around the light source causes glare.
