Kelompok pembudidaya ikan sadewa muda mandiri saat ini masih mengalami permasalahan dalam pembudidayaan ikan, hal ini dikarenakan control dan monitor mash dilakukan secara manual. Beberapa parameter yang terus dipantau oleh pembudidaya adalah PH, Kadar nutrisi air, dan suhu. Hal ini tentu saja tidak efektif dan memakan waktu. Oleh karena itu perlu system yang dapat melakukan monitoring terhadap parameter PH, kadar nutrisi air, dan suhu air, dan juga dapat melakukan control terhadap kualitas air. Hal ini dikarenakan kualitas air merupakan hal yang penting untuk budidaya ikan dengan teknologi bioflok. Dengan adanya system ini maka monitoring dan control dapat dilakukan dengan mudah lewat aplikasi mobile yang dapat terintegrasi dengan alat di luar, sehingga pembudidaya ikan tidak perlu datang dan melihat kondisi kolam secara berkala. Kegiatan pengabdian dilakukan dengan survei, persiapan pembuatan alat, pembuatan alat, integrasi alat, pengujain system, dan pelaksanaan kegiatan. Sistem ini sudah melakukan berbagai pengujian, seperti pengujian akurasi dan pengujian fungsional.

Répercussions de la pandémie et idées suicidaires chez les adultes au Canada : une enquête populationnelle transversale
Authors: Liu Li , Pollock Nathaniel J. , Contreras Gisèle , Tonmyr Lil , Thompson Wendy
Published: December 2022

Introduction

D’après de récentes données probantes, il y aurait eu une augmentation des idées suicidaires au cours de la pandémie de COVID-19. Notre recherche visait à estimer la probabilité de la présence d’idées suicidaires chez les adultes du Canada ayant subi des répercussions de la pandémie et à caractériser l’évolution de cette probabilité tout au long de la pandémie.

Méthodologie

Nous avons analysé les données regroupées issues des deux cycles de l’Enquête sur la COVID-19 et la santé mentale, à laquelle ont participé 18 936 adultes de 18 ans et plus, qui ont répondu aux questions du 11 septembre au 4 décembre 2020 puis du 1er février au 7 mai 2021. Nous avons estimé la prévalence des idées suicidaires depuis le début de la pandémie puis nous avons évalué, par régression logistique, la probabilité d’idées suicidaires chez les adultes ayant subi des répercussions de la pandémie, en fonction de facteurs de risque sociaux, de l’état mental général, d’indicateurs de bonne santé mentale et des stratégies d’adaptation.

Résultats

Les adultes ayant eu des expériences négatives liées à la pandémie présentaient un risque significativement plus élevé d’avoir des idées suicidaires, avec une relation dose-réponse manifeste. Les personnes ayant augmenté leur consommation d’alcool ou de cannabis, se disant inquiètes de la violence à la maison ou présentant des symptômes modérés à graves de dépression, d’anxiété ou de trouble stress post-traumatique avaient également un risque significativement plus élevé d’idées suicidaires. Le risque était significativement plus faible chez les personnes se percevant comme ayant une bonne santé mentale ou ayant fait état d’un fort sentiment d’appartenance à leur communauté ou d’une grande satisfaction à l’égard de la vie, qui faisaient de l’exercice pour se maintenir en bonne santé mentale ou physique ou qui s’adonnaient régulièrement à un passe-temps.

Conclusion

La pandémie de COVID-19 a une influence sur les idées suicidaires au Canada. Les données probantes de notre étude pourront servir à mettre au point des interventions sanitaires ciblées en vue de la prévention du suicide.
Problems of implementation of the state agricultural policy in the sphere of agricultural land using
Authors: Stanislavskyi V.
Published: December 2022

The article is devoted to the study of legal problems of the implementation of the state agrarian policy in the field of rational land use and the prospects for further planning of land ownership and land use of newly created agribusiness entities, as well as the development of scientifically based conclusions and proposals from the scientific doctrine of agrarian law of Ukraine. The priority directions of the implementation of the national policy in the field of land relations are highlighted, in particular, the implementation and financial support of national programs for the use and protection of land, reduction of plowed land, reproduction and increase of soil fertility, agroforestry and land reclamation, reclamation of disturbed lands, standardization and regulation in the field of land protection. The key role of land management and land use planning, in particular their zoning, is proven as one of the main mechanisms for coordinating economic interests and preserving and reproducing soil fertility, protecting agricultural land from the destructive processes of water and wind erosion, with the help of which the process of economic activity on the land is adapted to its properties. It is argued that today the projects of the organization of the territory of land use of enterprises, institutions, organizations and citizens regarding the creation of spatial conditions that ensure the ecological and economic optimization of the use and protection of land, the improvement of the ratio and placement of land plots, the development of a system of measures for the preservation and improvement of natural landscapes, the conservation of degraded and unproductive lands are virtually absent. Has been emphasized that the necessary prerequisite for the development of planning and implementation of sustainable agricultural land use in Ukraine and the regulation of further directions for the formation and implementation of the state agrarian policy is an ecological approach, which is capable of forming the social responsibility of agribusiness entities in the field of environmental protection, and will also be an incentive for the introduction environmentally safe agricultural technologies, including organic farming, precision farming, agroforestry during agricultural activities. The methodology of researching legal problems of rational land use in agriculture is based on the provisions of the general scientific dialectical method of scientific knowledge. In addition, formal-logical, formal-legal and hermeneutic methods were used to achieve the research goal.
DE L’INTERMÉDIAIRE DANS LA PHILOSOPHIE DE L’ESPACE : PRÉCARITÉ, CRÉATION, LIBERTÉ
Authors: MIHALI Ciprian
Published: December 2022

The Intermediary in the Philosophy of Space: Precariousness, Creation, Freedom. The reflection proposed by this text is the result of a dialogue spread over several years between philosophers and geographers. The best common ground between each other – in the right middle of the road – is undoubtedly the concept of the intermediary, which describes, negatively or affirmatively, the future of our physical, social, conceptual spaces and which speaks to us about discontinuity, hybridization, flow, contiguity, but also vulnerability, counterpowers and freedom. We wanted to show that far from being a concept of the residual, the unassimilable, the incomprehensible or even the irrational, the intermediary is the place of hospitality, the open work of alternative creativity, resistance, or affirmation of those who, excluded from dominant discourses, claim a right to speak and freely participate in social life.
Inspectoras de Primera Enseñanza en la provincia de Segovia (1900-1939). Una historia silenciada
Authors: Sonlleva Velasco Miriam , Sanz Simón Carlos
Published: December 2022

En la década de 1910, las inspectoras que lograron llegar a las primeras plazas tenían una excelente formación y una amplia experiencia profesional. Sin embargo, tuvieron que demostrar su valía ante la desconfianza de un cuerpo profesional eminentemente masculinizado. Cien años más tarde, muchas de ellas permanecen aún en el olvido. La presente investigación pretende analizar las trayectorias personales y profesionales de las pioneras de la inspección educativa en la provincia de Segovia. A través de un discurso interpretativo y hermenéutico, descubrimos que demostraron un fuerte compromiso hacia la mejora de la educación femenina, colaboraron con entusiasmo en reformas educativas llevadas a cabo en la República y sufrieron las consecuencias de la depuración en la Guerra Civil.

Authors: Marwan Marwan , Isnaeni Nurul
Published: December 2022

Presidensi G20 Indonesia menetapkan pariwisata sebagai salah satu sektor prioritas dalam program pemulihan ekonomi pasca Covid-19. Sebelum terjadi pandemi global Covid-19, pariwisata merupakan sektor andalan dalam pertumbuhan ekonomi nasional dan global. Artikel ini membahas sentralitas peran negara untuk mendorong pembangunan pariwisata yang berkelanjutan. Artikel ini menggunakan metode studi kasus tunggal, observasi, dan wawancara. Analisis tulisan menggunakan perspektif Environmental-State untuk menganalisis peran strategis negara untuk mempromosikan norma keberlanjutan dalam pembangunan sektor pariwisata. Kesimpulan menunjukkan bahwa negara sangat berperan dalam mengarahkan sekaligus menentukan proses pembangunan pariwisata berkelanjutan di Wakatobi. Ada tiga modalitas negara yang tidak dimiliki oleh aktor lain yang sangat berpengaruh dalam mendukung peran sentral negara, yakni: otoritas legal formal, anggaran yang berkelanjutan, dan jaringan birokrasi. Oleh karenanya, kepemimpinan negara sebagai �environmental state� dengan visi dan komitmen yang kuat tentang keberlanjutan akan sangat menentukan bagi keberhasilan pembangunan pariwisata berkelanjutan.
Design of Novel Multiband Radar Absorbers Using Cylindrical Frequency Selective Surfaces
Authors: Fakhte Saeed
Published: December 2022

In this paper, a novel ultra-thin and multi-band radar absorber structure using cylindrical frequency selective surfaces (FSS) is proposed. The unit cell of the structure consists of a curved square ring printed on a cylindrical dielectric spacer to realize strong resonance to achieve efficient absorption of the incident microwave energy. The use of novel cylindrical FSS coating results in a considerable decrease of the radar cross section of a perfect electric cylinder. Furthermore, our studies prove that the proposed absorbing structure can be easily scaled to desired frequencies, and extension to dual- and multiband performances is possible. Meanwhile, the operational principle of the proposed absorbers is briefly introduced.
Quantifying the changes in the tumour vascular micro-environment in spinal metastases treated with stereotactic body radiotherapy - a single arm prospective study

Published: December 2022

Background

The primary objective was to quantify changes in vascular micro-environment in spinal metastases (SM) patients treated with stereotactic body radiotherapy (SBRT) with multi-parametric dynamic contrast enhanced (DCE) magnetic resonance imaging (MRI). The secondary objective was to study plasma biomarkers related to endothelial apoptosis.

Patients and methods

Patients were imaged with DCE-MRI at baseline/1-week/12-weeks post-SBRT. Metrics including normalised time-dependent leakage (Ktrans), permeability surface product (PS), fractional plasma volume (Vp), extracellular volume (Ve) and perfusion (F) were estimated using distributed parameter model. Serum acid sphingomyelinase (ASM) and sphingosine-1-phosphate (S1P) were quantified using ELISA. Clinical outcomes including physician-scored and patient-reported toxicity were collected.

Results

Twelve patients (with varying primary histology) were recruited, of whom 10 underwent SBRT. Nine patients (with 10 lesions) completed all 3 imaging assessment timepoints. One patient died due to pneumonia (unrelated) before follow-up scans were performed. Median SBRT dose was 27 Gy (range: 24–27) over 3 fractions (range: 2–3). Median follow-up for alive patients was 42-months (range: 22.3–54.3), with local control rate of 90% and one grade 2 or higher toxicity (vertebral compression fracture). In general, we found an overall trend of reduction at 12-weeks in all parameters (Ktrans/PS/Vp/Ve/F). Ktrans and PS showed a reduction as early as 1-week. Ve/Vp/F exhibited a slight rise 1-week post-SBRT before reducing below the baseline value. There were no significant changes, post-SBRT, in plasma biomarkers (ASM/S1P).

Conclusions

Tumour vascular micro-environment (measured by various metrics) showed a general trend towards downregulation post-SBRT. It is likely that vascular-mediated cell killing contributes to excellent local control rates seen with SBRT. Future studies should evaluate the effect of SBRT on primary-specific spinal metastases (e.g., renal cell carcinoma).
Dose-escalated radiotherapy with simultaneous integrated boost for bone metastases in selected patients with assumed favourable prognosis
Authors: Potkrajcic Vlatko , Mueller Arndt-Christian , Frey Bettina , Gani Cihan , Zips Daniel , Hoffmann Ruediger , Frantz Sandra , Warm Verena , Paulsen Frank , Eckert Franziska
Published: December 2022

Background

Stereotactic body radiotherapy (SBRT) concepts for dose escalation are increasingly used for bone metastases in patients with oligometastatic or oligoprogressive disease. For metastases that are not suitable for SBRT-regimens, a treatment with 30/40 Gy with simultaneous integrated boost (SIB) in 10 fractions represents a possible regimen. The aim of this study was to investigate the feasibility of this concept and the acute and subacute toxicities.

Patients and methods

Clinical records for dose-escalated radiotherapy of all consecutive patients treated with this regimen were evaluated retrospectively (24 patients with 28 target volumes for oncologic outcomes and 25 patients with 29 target volumes for treatment feasibility and dose parameters analysis). Analysis of radiotherapy plans included size of target volumes and dosimetric parameter for target volumes and organs at risk (OAR). Acute and subacute toxicities were evaluated according to Common Terminology Criteria for Adverse Events (CTCAE) V4.0.

Results

The most common localization was the spine (71.4%). The most common histology was prostate cancer (45.8%). Oligometastatic or oligoprogressive disease was the indication for dose-escalated radiotherapy in 19/24 patients (79.2%). Treatment was feasible with all patients completing radiotherapy. Acute toxicity grade 1 was documented in 36.0% of the patients. During follow up, one patient underwent surgery due to bone instability. The 1-year local control and patient-related progression-free survival (PFS) were 90.0 ± 6.7% and 33.3 ± 11.6%, respectively.

Conclusions

Dose-escalated hypofractionated radiotherapy with simultaneous integrated boost for bone metastases resulted in good local control with limited acute toxicities. Only one patient required surgical intervention. The regimen represents an alternative to SBRT in selected patients.
Citrullus colocynthis (L.) Schrad (Bitter Apple): An Overview of its Traditional Uses, Phytochemistry and Pharmacological Potential
Authors: Kamboj Anil , Dahiya Randhir Singh

Phytochemicaly the compounds like glycosides, alkaloids, flavonoids, phenolic acids fatty acids, carbohydrates and essential oils were reported from the plant and the main components isolated from the Citrullus colocynthis plant are Cucurbitacins. The plant has been studied extensively for its wide range of pharmacological activities, which include anticancer, antidiabetic, antioxidant, cytotoxic, antimicrobial, anti-inflammatory antilipidemic, and insecticide but the therapeutic potential for cardiovascular, gut, airways and many other diseases remain to be explored.
Non-Archimedean Koksma Inequalities, Variation, and Fourier Analysis
Authors: Petsche Clayton , Somasunderam Naveen
Published: December 2022

We examine four different notions of variation for real-valued functions defined on the compact ring of integers of a non-Archimedean local field, with an emphasis on regularity properties of functions with finite variation, and on establishing non-Archimedean Koksma inequalities. The first version of variation is due to Taibleson, the second due to Beer, and the remaining two are new. Taibleson variation is the simplest of these, but it is a coarse measure of irregularity and it does not admit a Koksma inequality. Beer variation can be used to prove a Koksma inequality, but it is order-dependent and not translation invariant. We define a new version of variation which may be interpreted as the graph-theoretic variation when a function is naturally extended to a certain subtree of the Berkovich affine line. This variation is order-free and translation invariant, and it admits a Koksma inequality which, for a certain natural family of examples, is always sharper than Beer’s. Finally, we define a Fourier-analytic variation and a corresponding Koksma inequality which is sometimes sharper than the Berkovich-analytic inequality.

Performance Differences between ESG Indices and Conventional Market Indices: a Multivariate Analysis of Indices
Authors: Kurnoga Nataša , Šimurina Nika , Fučkan Filip
Published: December 2022

This paper aims to identify performance differences between conventional European equity indices and ESG indices. Conventional European equity indices are tools both institutional and retail investors use to understand the overall state of the market, as well as a benchmark for comparing investment decisions. ESG indices or sustainability indices are different from conventional market indices and can provide information to investors about the firm’s sustainability performance, they are new and constantly developing stock market indices taking into account environmental, social, and governance considerations. The indices were analysed by multivariate analysis. Since we could collect data by country only for conventional indices, cluster analysis based only on those indices was performed. The following variables of conventional indices were analysed: year-to-date price return, annualized 3-year price return, annualized 5-year price return, and annualized 10-year price return. The paper also compares ESG indices and conventional indices, and in most cases, they have no significant performance differences.

Bài viết tiếp cận vấn đề nghiên cứu từ góc nhìn đồng đại động, phân tích hình ảnh người phụ nữ dựa trên ngữ liệu tục ngữ tiếng Hàn. Các thao tác khảo sát tư liệu, phân loại các đơn vị tục ngữ theo các phạm trù ngữ nghĩa, phân tích và liên hệ với tiếng Việt được sử dụng kết hợp một cách linh hoạt nhằm giải quyết hiệu quả các vấn đề nghiên cứu. Kết quả nghiên cứu cho thấy hình ảnh mang sắc thái tiêu cực của người phụ nữ được phản ánh khá đa đạng trong tục ngữ.
Có thể thấy rõ sự thiếu công bằng, thái độ thiếu thiện ý mang đậm sự phân biệt trong đối xử, thậm chí là có phần tàn nhẫn đối với thói hư tật xấu của người phụ nữ
. Cuộc đời của người phụ nữ được phác họa trong tục ngữ với thân phận của kẻ yếu thế, luôn phải cam chịu, phụ thuộc vào người khác. Vòng luẩn quẩn của mối quan hệ mẹ chồng nàng dâu cho thấy cuộc đời bế tắc của người phụ nữ, ý thức về sự bình đẳng, sự tôn trọng đối với phụ nữ bị “phong ấn” một phần bởi đạo đức Nho giáo. Đây cũng chính là giá trị lên án những bất công trong xã hội phong kiến với tiêu chuẩn tứ đức, qui tắc tam tòng của đạo đức Nho giáo của tục ngữ.

The purpose of the article is to examine, on the basis of field ethnographic materials collected by the authors in the Tyumen, Omsk and Novosibirsk regions during a number of field seasons, the relics of shamanism preserved in the folk medicine of the Siberian Tatars. The relevance of the study is related to the poor knowledge of this issue. The object of the study is the relics of the pre–Islamic beliefs of the Siberian Tatars, including the categories of shamans (imce, kuremce, sihyrce, kotsle mullah, etc.). The subject is their role in the traditional healing and magical rituals. The authors believe that with the spread of Islam in Western Siberia, there is a loss or significant transformation of the early common Turkic ideas about the universe, nature and essence of man. But, despite this, some elements of the common Turkic cultural and religious practice have been preserved in the culture of the Siberian Tatars. The main conclusions of the authors are the following. Magical rituals occupied a significant place in the traditional folk medicine of the Siberian Tatars. The authors show the preservation of some relics of shamanism among the Siberian Tatars, as well as categories of shamanists, which include imce, kuremce, sihyrce. The similarities and differences in their capabilities in traditional medical practice are shown: clairvoyance (kuremce, imce, sihyrce), diagnosis of diseases, treatment (imce, kuremce, sihyrce), kamlaniya (imce, sihyrce), prediction of the future, communication with spirits (kuremce, sihyrce). In connection with the important role of Sufism in Siberian Islam, it is shown that the practices inherent in shamanism were used in the treatment of Islamic clerics - mullahs.

BACKGROUND: Understanding nurses’ knowledge and attitudes might be important in influencing their behaviors of complying with pressure injury prevention measures in the operating room. PURPOSE: The aim of this descriptive and cross-sectional study was to determine operating room nurses’ knowledge and attitudes about pressure injury prevention. METHODS: This study was performed with 174 nurses working in the operating rooms of 5 hospitals in Istanbul between July and October 2020. The data were collected with the Modified Pieper Pressure Ulcer Knowledge Test-MPPUKT and Attitude Towards Pressure Ulcer Prevention Instrument-APuP and analyzed with parametric and nonparametric tests using the SPSS 20.0 package program. The statistical significance level was accepted as P < .05. RESULTS: The total mean score of the MPPUKT of the operating room nurses was 32.72 ± 6.65, and the knowledge level of only 57.5% of the nurses was considered sufficient (MPPUKT score ≥ 70%); the total mean score of the APuP was 44.67 ± 3.10, and almost all (94.8%) had a satisfactory attitude (≥75%). In addition, there was a significant positive correlation between the knowledge and attitudes of the operating room nurses about pressure injury prevention (P = .000). CONCLUSION: This study has shown that the knowledge level of the operating room nurses was weak and their attitudes were satisfactory. It is recommended to improve the knowledge and attitudes of operating room nurses to prevent pressure injuries through effective in-service training programs.
Near-infrared photon upconversion and solar synthesis using lead-free nanocrystals

Near-infrared to visible photon upconversion holds great promise for a diverse range of applications. Current photosensitizers for triplet-fusion upconversion across this spectral window often contain either precious or toxic elements, and have relatively low efficiencies. Although colloidal nanocrystals have emerged as versatile photosensitizers, the only family of nanocrystals discovered for near-infrared upconversion is the highly-toxic lead chalcogenides. Here we report zinc-doped CuInSe2 nanocrystals as a low-cost and lead-free alternate, allowing for near-infrared to yellow upconversion with an external quantum efficiency reaching 16.7%. When directly merged with photoredox catalysis, this system enables efficient near-infrared-driven organic synthesis and polymerization, which in turn solves the issue of reabsorption loss for nanocrystal-sensitized upconversion. Moreover, the broadband light capturing of these nanocrystals allows for very rapid reactions under indoor sunlight. Extending the reach of "solar synthesis" into the near-infrared may realize the century-long dream of conducting high added-value chemical transformations using sunlight.

Empirical models, previously called land-use regression (LUR), are used to understand and predict spatial variability in levels of outdoor air pollution at unmeasured locations, for example, to conduct health risk assessment, environmental epidemiology, or environmental justice analysis. Many methods are used to generate empirical models, yet almost no research compares models generated by separate research groups. We intercompare six national-scale empirical models for year-2010 concentrations of PM2.5 in the US, each generated by a different research group. Despite substantial differences in the statistical methods and input data used to build the models, our main finding is a relatively high degree of agreement among model predictions. For example, in pairwise intercomparisons, the average Pearson correlation coefficient is 0.87 (range: 0.84 to 0.92); the RMSD (root-mean-square-difference; units: μg/m3) is 1.1 on average (range: 0.8 to 1.4), or ~12% of the average concentration; and many best-fit lines are near the 1:1 line. The underlying reason for this agreement is likely that, while the methods and the independent variables differ among the models, in all cases the models are built using, and are calibrated to, the same information: publicly available measurement at US EPA regulatory monitoring stations. Findings here suggest that future improvements to national empirical models will come not from further refinements to the methods (e.g., more-advanced models) but from employing a fundamentally different set of observations, in addition to regulatory monitoring data.
