MOTIVASI DAN KEPUTUSAN BERKUNJUNG WISATAWAN KE KEBUN RAYA BEDUGUL PADA MASA PANDEMI
Authors: Wulandani Ni Luh Kadek Laksmi
Published: May 2023

Pada masa pandemi Covid-19 diterapkan kebijakan PPKM di seluruh Indonesia, tidak terkecuali di Bali. Imbas dari kebijakan tersebut adalah berkurangnya kunjungan wisatawan. Menindak hal tersebut, beberapa daya tarik wisata memberikan potongan harga tiket masuk. Namun Kebun Raya Bedugul melakukan hal sebaliknya dengan menaikan harga tiket masuk. Tiket masuk adalah salah satu indikator yang menentukan motivasi berkunjung wisatawan, ketika harga mengalami kenaikan, motivasi berkunjung cenderung akan turun. Namun setelah mengalami kenaikan harga, jumlah kunjungan Kebun Raya Bedugul menempati posisi pertama jumlah kunjungan terbanyak di Kabupaten Tabanan. Tujuan dari penelitian ini adalah untuk mengidentifikasi motivasi dan keputusan berkunjung wisatawan serta mencari pengaruhnya. Teknik analisis yang digunakan adalah regresi linear berganda. Hasil yang didapat adalah motivasi pendorong yang memiliki nilai paling tinggi adalah relaxation sedangkan untuk motivasi penarik adalah natural environment and weather attraction. Hasil selanjutnya adalah adanya pengaruh positif signifikan antara motivasi penarik dan pendorong terhadap keputusan berkunjung sebesar 47,8% sedangkan sebesar 52,2% sisanya dipengaruhi oleh variabel lain di luar model penelitian ini.
Effect of High Solid Concentration on Friction in a Transitional and Turbulent Flow of Bioliquid Suspension
Authors: Bartosik Artur S.
Published: May 2023

Some suspensions in nature have a complex structure and demonstrate a yield shear stress and a non-linear relationship between the shear rate and the shear stress. Kaolin clay suspension is such an example in engineering, whereas in nature it is blood. This study represents an innovative approach to simulate bioliquid flow, similar to that of blood when the solid concentration is high. The objective of this study is to examine the influence of high solid concentration of bioliquid, similar to blood, on energy losses and velocity profiles in turbulent and transitional flow in a narrow tube. Using the analogy between the suspension of kaolin clay and blood, the physical model and the mathematical model were formulated. The mathematical model comprises continuity and time-averaged momentum equations, a two-equation turbulence model for low Reynolds numbers, and a specially developed wall damping function, as such suspensions demonstrate the damping of turbulence. Experimental data on blood rheology for solid concentrations equal to 43% and 70% by volume, gathered from the literature, were used to establish a rheological model. The results of the simulations indicated that an increase of solid concentration in bioliquid suspension from 43% to 70% causes an increase in wall shear stress to approximately 10% and 6% for transitional and turbulent flow, respectively, and changes in velocity profiles. Such simulations are important if an inserted stent or a chemical additive to the bioliquid suspension is considered, as they can influence the shear stress. The results of the simulations are presented in graphs, discussed, and conclusions are formulated.
Personal Deixis in Political Discourse
Authors: Alsultan Abdullah
Published: May 2023

Deixis is manifested especially as the pronouns I, you and he. It is possible to appoint the person producing the discourse and the participant in it. Deixis may be received, accompanied by gestures, to express a specific purpose and help the addressee communicate the meaning of what is referred to. When using a pronoun, you refer to one of the parties to the discourse and determine their place in it, especially if the speaker has political authority. The mechanism used by deixis to direct the discourse and the success of the communication process is important to clarifying the speaker's intention in a contemporary political discourse. An example of this is the discourse of Saudi Crown Prince Mohammed bin Salman at the G-20 summit and his use of deixis to understand, persuade and influence, as well as his statement on the nature of the relationship between the speaker and his addressees. This study clarifies the nature of deixis in general and personal deixis in particular. It explores their types and presents the study model for analysis according to the pragmatic approach to explain the status of the counselors and their importance in the analysis of political discourse.

Rough draft mathematics als Zugang zu Problemlöseaufgaben für inklusive Lerngruppen
Authors: Bräuning Kerstin , Feskorn Caren
Published: May 2023

Probleme lösen zu können, weist eine große Bedeutung für mathematisches Lernen als auch für das tägliche Leben auf. Daher sollte allen Schüler:innen ein Zugang dazu ermöglicht werden. Bisher gibt es jedoch kaum empirische Untersuchungen zu den Problemlösefähig- und -fertigkeiten von mathematisch leistungsschwächeren Schüler:innen oder inklusiven Lerngruppen. In unserer Studie analysieren wir daher, in welcher Weise mit Hilfe des methodischen Vorschlags „Rough Draft Mathematics“ (Jansen, 2020a) in einer inklusiven Lerngruppe Schüler:innen dabei unterstützt werden, einen Zugang zu Problemlöseaufgaben (hier: Pferde-Fliegen-Aufgabe; Wittmann & Müller, 2005, S. 68) zu finden, bei der zwei Gleichungen mit zwei Unbekannten gelöst werden sollen. Im Beitrag wird anhand einer videografierten Unterrichtssequenz die Aufgabeninitiierung im Plenum einer 4. Klasse analysiert, in der die Schüler:innen gemeinsam erste Ideen, sogenannte „rough drafts“, zur Bearbeitung der Problemlöseaufgabe sammeln. Dabei wird deutlich, dass die Äußerungen der Schüler:innen weit über das bloße Rezipieren der Aufgabenstellung hinausgehen und somit bereits der Einstieg mittels „Rough Draft Mathematics“ eine vertiefte Auseinandersetzung mit der Problemlöseaufgabe zeigt. Außerdem wird herausgearbeitet, dass Schüler:innen sich auch auf Ideen und Äußerungen ihrer Mitschüler:innen beziehen und diese zum Teil sogar erweitern. Die Ergebnisse zeigen, dass Rough Draft Mathematics eine soziale Praktik für den inklusiven Mathematikunterricht, vor allem auch für das Problemlösen, darstellen könnte.

Published: May 2023

Dalam penelitian berbasis studi literatur ini menghasilkan suatu temuan mengenai fenomena masuknya budaya asing akibat adanya pengaruh globalisasi dan Pancasila adalah sebagai filter dari masuknya budaya asing tersebut. Penerrapan nilai-nilai Pancasila perlu dimulai sejak dalam lingkungan rumah, sekolah, maupun masyarakat. Oleh karena itu pentingnya peneraapan nilai-nilai Pancasila sebagai tolak ukur pencapaian nilai, etika, moral serta sikap dalam perilaku sehari-hari. Jadi dengan adanya penerapan nilai-nilai Pancasila ini diharapkan peserta didik dapat mengaplikasikan dan mengimplementasikan dalam proses pembelajaran seperti dengan melakukan hal-hal sederhana contoh berdoa sebelum memulai pelajaran, mentaati peraturan dan tata tertib sekolah, rukun berteman dengan mengedepankan sikap toleransi, aktif dan partisipatif dalam diskusi guna menyampaikan pendapat, berperilaku adil tidak membeda-bedakan. Tetap mengedepankan semboyan Bhineka Tunggal Ika. Demikian halnya dengan penerapan nilai-nilai dasar Pancasila dalam mata pelajaran PPKn di lembaga pendidikan sekolah yang memerlukan koordinasi anta pendidik dan peserta didik agar tercapai proses pembelajaran PPKn yang sesuai dengan nilai-nilai Pancasila.
Tradisi Seserahan Dalam Pelestarian Budaya Dan Kearifan Lokal Menurut Pandangan Islam
Authors: Riftiansyah Rizki , Abduh Mohamad , Rifai Moh , Saepudin M Asep , Martiah Martiyah
Published: May 2023

Di desa Sumbersari Pebayuran Bekasi memiliki tradisi yang telah dilakukan oleh nenek moyang mereka dari dulu hingga sekarang. Tentunya sangat menarik ketika sebuah adat  tidak tertera  dalam sumber pokok hukum Islam yaitu al-Qur’an dan al-Hadisth. Di desa Sumbersari   terdapat tradisi pemberian barang maupun harta dari pihak laki-laki terhadap pihak perempuan dengan tujuan membantu melancarkan tahapan-tahapan sebelum akad dan resepsi pernikahan dilasanakan, yang disebut dengan seserahan. Seserahan adalah penyerahan calon pengantin laki-laki ke pihak mempelai perempuan untuk dinikahkan pada sore hari sehari sebelum akad nikah dilakukan. Pendekatan dalam penelitian ini adalah penelitian lapangan (Field Research ) karena untuk memahami  tradisi seserahan dalam pelestarian budaya dan kearifan local  yang digunakan masyarakat desa Sumbersari Pebayuran Bekasi, menuntut peneliti untuk terjun langsung dalam kegiatan masyarakat yang ada di desa Sumbersari tersebut dengan tujuan untuk mendapatkan informasi yang mendalam. Teknik yang digunakan untuk mengumpulkan data dilakukan melalui observasi, wawancara dan studi pustaka. Berdasarkan hasil penelitian yang telah dilakukan, dapat disimpulkan bahwa pandangan Islam terhadap seserahan adat Sunda yang dilakukan oleh masyarakat desa Sumbersari dengan menyertakan sesaji dalam proses seserahan yang di persembahkan kepada arwah nenek moyang yang dipercaya dapat melancarkan acara merupakan urf yang fasid, karena sesaji dilarang dalam ajaran Islam dan mengandung unsur syirik. Sehingga seserahan di desa Sumbersari tidak sesuai dengan ajaran Islam, dan masyarakat harus meninggalkan kebiasaan menyertakan sesaji dalam seserahan.

Published: May 2023

Penelitian ini bertujuan untuk mengetahui secara lebih dalam mengenai isu-isu atau permasalahan pelanggaran HAM yang terjadi di Papua dan peranan lembaga-lembaga terkait dalam mengatasi permasalahan pelanggaran HAM di Papua. Selain itu penelitian ini juga bertujuan untuk memberikan beberapa poin-poin solusi yang dapat membantu mengatasi pelanggaran HAM yang ada di Papua, seperti rencana pembangunan papua berkelanjutan, perlindungan hukum bagi aktivis HAM Papua, membentuk tim pengawas HAM secara khusus, menggalakkan isu-isu pelanggaran HAM Papua melalui pers mahasiswa, mengadakan kampanye sosial dan solusi lainnya. Penulis juga memberikan data-data realistis dari beberapa sumber yang terpercaya sebagai studi pustaka yang dapat mendukung argumentasi dan pelaksanaan solusi-solusi yang penulis berikan. Isu Papua Merdeka muncul dikarenakan beberapa faktor, yaitu adanya diskriminasi terhadap orang Papua, pembangunan Papua yang kurang mendapat perhatian, kurangnya kebijakan serta peranan lembaga HAM yang dapat melindungi, sikap diskriminatif masyarakat luar terhadap orang Papua, dan lain sebagainya. Pembangunan di Papua pun masih bilang tertinggal dibandingkan dengan provinsi lainnya yang menyebabkan kualitas hidup masih terbilang jauh dari kata baik. Ditambah lagi dengan sikap masyarakat yang masih kurang peduli dengan apa yang terjadi di Papua. Oleh karena itu, sebagai masyarakat Indonesia kita harus meningkatkan kepedulian kita terhadap sesama masyarakat Indonesia tanpa terkecuali. Hal ini demi terwujudnya keadilan dengan menegakan hukum sesuai dengan filosofis yang terdapat dalam filsafat hukum. Untuk mengatasi permasalahan tersebut juga dapat dilakukan dengan peningkatan lembaga HAM, kebijakan mengenai HAM dan pembangunan berkelanjutan di Papua, serta baik masyarakat maupun pemerintah lebih peduli lagi dengan isu-isu mengenai diskriminasi dan pelanggaran HAM.

A study on memory reproduction in the memoirs of writers after the war
Authors:   Korean Association for Literacy, Lee Mi-Jung
Published: May 2023

This study aims to analyze the representation of war in the memoirs of postwar writers, 90 days of hardship. Memoirs of the war contain a self-proof of the purpose of surviving in South Korea. The state deployed literary men in cultural projects to spread anti-communist ideology. The book produced as part of this program is 90 days of hardship. The national anthem emphasized the North Korean military’s reality, South Korea’s position in the international situation of June 25, and the victims’ consciousness. Memoirs played the role of spreading the memory of the nation at that time.
Yu Jin-oh and Mo Yun-suk, Korea University professor Lee Kun-ho, and former Hansung Ilbo political and police chief Koo Cheol-hoe wrote this book. They recalled their experiences during the occupation of Seoul by North Korea. The narrative structure of Yu Jin-oh and Mo Yun-suk’s writings highlights the central character and ventures through hardships and overcoming. While Yu Jin-oh described fragmented psychological experiences in which the rational self collapsed, Mo Yun-suk emphasized the tragic story of the victim. Their writings explored the true story and revealed the historical reality. On the other hand, the writings of Lee Kun-ho and Gu Cheol-hoe eliminated the subject of memory, eloquently expressed anti-communism, and maximized the horrors of war.
90 days of hardship echoed the national identity and spread the anti-communist ideology. It specified the victims of the war and embodied the confrontation between the South and the North. ‘Remembering’ is the task of establishing meaning to individual and collective identities. This was an important purpose for investigating the war after the restoration of Seoul in 1950.

Authors: Sarki Muktar
Published: May 2023

This study attempted to investigate the effects of dictation on the written word spelling of Junior Secondary School JSS III students in Jigawa state. The study was motivated by the difficulty faced by learners of English as L2 in spelling of words especially the irregular spelling in their essays. Two research questions were set and answered. The target population was the JSS III students in Jigawa State. The study was conducted in the 2022/2023 academic session. Experimental research design was adopted for the study. 150 students were randomly sampled from two JSS within two senatorial districts in the state and were equally assigned as experimental and control groups. The instruments used were the selected and modified words from JSS course books which were the English words selected and modified from JSS course books which were used for the pre-test and post-test respectively. The research questions were answered in form of table showing the frequency and percentage. The major findings of the study showed that 48% of the participants in the experimental group spelt more irregular words while only 33% spelt the same words in the control group after the treatment. The study recommended that teachers of English as a second language should be trained so that they would be more sensitive to dictation strategies that enable them to teach JSS students to acquire ability of spelling more regular and irregular words.

Economic Community of West African States (ECOWAS) Protocol On Free Movement and National Security: A Case Study of Nigeria
Authors: Omoyeni Tolulope Julius
Published: May 2023

Ensuring the safety and security of countries is a priority for governments worldwide. As a member of the Economic Community of West African States (ECOWAS), Nigeria has supported the integration and movement of goods, people, and services through the adoption of the Protocol on Free Movement (PFM). However, the unrestricted movement of people across porous borders can pose security threats, particularly with the trafficking of small arms and light weapons (SALW). This paper examines the potential security threats that could arise from the protocol on free movement of people and goods and highlights the importance of collaboration with other countries to achieve safe and secure borders. The study utilized a desk research method that relied heavily on secondary data to analyze relevant materials. The findings indicate that while the protocol enhances economic integration and financial stability, organized transnational criminal networks have taken advantage of free movement to perpetuate various forms of crime such as human trafficking, arms trafficking, and terrorism. The paper argues that regional integration is crucial but must be balanced with the need to maintain National Security in Nigeria. To address the challenges posed by free movement, the paper recommends that the Nigerian government needs to be strategic while endorsing international treaties to reflect the national interest of securing the Country. Strategies should be developed to monitor porous borders to check the illegal flow of arms, and efforts should be made to mop up illegal arms through the speedy establishment of the National Commission for the coordination and control of the proliferation of small Arms and Light Weapon (NATCOM) bill awaiting assent from the president. Additionally, intelligence sharing should be enhanced to promote regional integration while maintaining national security.
La importancia de la prosa de Gabriela Mistral
Authors: Farías Rojas Gabriel Arturo , Cid Uribe Miriam Elizabeth
Published: May 2023

Este artículo consiste en un ensayo que se propone reflexionar sobre la literatura de Gabriela Mistral como una coalición entre poesía y prosa. Sin embargo, la consideración de ambas no es una tarea fácil de asumir ya que, tradicionalmente, su prosa ha sido ignorada. Afortunadamente, en la actualidad, la importancia de la prosa Mistraliana ha ido cobrando notoriedad en nuestra sociedad y, por ello, nuestro propósito principal pretende apoyar la investigación sobre su prosa en la actualidad. Por lo tanto, develar consideraciones históricas sobre la razón por la cual a Mistral se le otorgó un papel pedagógico particular en Chile resulta útil a la hora de comprender la selección parcial de su poesía por parte de la crítica literaria chilena, mientras que la mayor parte de ella junto con su prosa fueron soterradamente ocultadas al público. En segundo lugar, señalar los aspectos de su prosa que nos ayudan a ver su propia interpretación y posicionamiento sobre los momentos históricos en los que participó como, por ejemplo, su defensa de la paz mundial, es una baza innegable. Además, tanto el reconocimiento de la subjetividad de Mistral como de los trabajos actuales que rescatan el aporte literario de su prosa se muestran como nuestra última reflexión sobre la imposibilidad de seguir descuidando la investigación que se está realizando sobre su prosa a partir de ahora hasta que no quede nada más por descubrir sobre ella. pero sólo si ello llega alguna vez a suceder.

PCR-RFLP Based Detection of atypical Mycobacteria Isolated from Aquatic Environment
Authors: Saha Tirthankar , Das Parijat , Sengupta Tapti
Published: May 2023

Non-tuberculous mycobacteria (NTM) serve as the causative agent for fish tuberculosis which is a chronic progressive disease covering a vast range of cultured and wild, freshwater and marine environments in different climatic conditions. Detection of environmental Mycobacteria in a conventional way is generally dependent on the basis of phenotypic, histopathological and biochemical characterization. The present study focused on the distribution and occurrence of mycobacterial pathogens in clinically infected fishes of a variety of species, water and soils from different aquaculture sources in West Bengal, India. Samples were collected from four distinct regions where fishes were examined for granulomatous inflammation. A total of 161 fishes, 127 water and 97 soil samples were examined and 132 (81.98 %), 65 (51.18 %) and 36 (37.11 %) appeared as acid-fast positive respectively. Presences of acid-fast bacteria within necrotic tissue of infected fishes were detected by Zn staining. Morphology, biochemical characteristics and 16S rRNA gene sequencing of bacteria were satisfactory to show the acid-fast bacilli belong to the Genus Mycobacteria. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was carried out to analyze the rpoB gene sequencing to confirm Mycobacteria down to the species level. Ten different NTM species were identified using PCR-RFLP analysis. Mycobacterium fortuitum type I was the most abundantly isolated species among all the sample sources. The present study suggests that water play a major role in the epidemiology of environmental Mycobacteria, infecting aquatic organisms and conducting potential public health hazard, especially those who are immune-compromised individual.

Antioxidant and antifungal efficacy of green synthesized silver nanoparticles
Authors: S Manju , Gowri Aishwarya  , NagaJyothi
Published: May 2023

The use of herbs have gained momentum in the contemporary research, as they possess several biological activities. Green synthesised nanoparticles are extensively under exploration due to their multi-faceted roles. The present work details the comparative antioxidant potentials of the leaves and seeds extracts of the herbs Coriander sativum (coriander), Trachyspermum ammi (Ajwain), Trigonella foenum-graecum (menthi) and synthesis of silver nanoparticles. The antifungal effects of the synthesized nanoparticles against a pathogenic species of Aspergillus flavus and the mode of action was also analysed. Results of the investigation showed that the seed extract of Ajwain and leaf extract of coriander exhibited the highest antioxidant properties and were used as reducing agents for silver nanoparticles synthesis. The nanoparticles were characterized by UV-visible absorption spectrum, Scanning Electron Microscopy-Energy Dispersive Spectra (SEM-EDS) and Transmission Electron Microscopy (TEM). The silver nanoparticles showed enhanced antioxidant activity when compared to the extracts. The antifungal studies showed that both the nanoparticles were effective against A. flavus, while C. sativum silver nanoparticle (Cs-AgNP) exhibited the highest activity. The mechanism of antifungal effect showed that the nanoparticles exerted a membranolytic activity on the pathogenic A. flavus. SEM images showed highly wrinkled mycelia in nanoparticles-treated samples and membrane permeabilization was evident from the 1- N-phenyl napththyl amine assay in nanoparticle-treated fungal samples. The activity of a transmembrane enzyme calcium ATPase was also significantly decreased in treated samples confirming the membrane damage effects of nanoparticles. Among the nanoparticles, Cs-AgNP showed the maximum effect. The efficacy of these green synthesized nanoparticles provides insight into their use as effective antifungal agents.

Published: May 2023

We present the results from a coordinated XMM-Newton + NuSTAR observation of the Seyfert 1 galaxy ESO 511−G030. With this joint monitoring program, we conduct a detailed variability and spectral analysis. The source remained in a low flux and very stable state throughout the observation period, although there are slight fluctuations of flux over long timescales. The broadband (0.3–78 keV) spectrum shows the presence of a power-law continuum with a soft excess below 2 keV, a relatively narrow iron Kα emission (∼6.4 keV), and an obvious cutoff at high energies. We find that the soft excess can be modeled by two different possible scenarios: a warm (kT
e ∼ 0.19 keV) and optically thick (τ = 18–25) Comptonizing corona or a relativistic reflection from a high-density (

A Dust Detection Database for the Inner Heliosphere Using the Parker Solar Probe Spacecraft
Authors: Malaspina David M. , Toma Alexandru , Szalay Jamey R. , Pulupa Marc , Pokorný Petr , Bale Stuart D. , Goetz Keith
Published: May 2023

A database of in situ dust impact detections made by the Parker Solar Probe spacecraft is created to facilitate studies of interplanetary dust dynamics in the inner heliosphere. A standardized dust detection methodology is established and tested for validity. Individual impact detections are included in the database, and are used to derive dust impact rates. Impact rates are corrected for effects related to high-amplitude plasma waves and undercounting due to finite detection window duration. These corrections suggest that: (i) most dust impacts on Parker Solar Probe are consistent with a random process; and (ii) the true dust impact rate may be ∼50% greater than the impact rate determined using uncorrected data for certain portions of the orbit, especially near perihelion.
Why “Solar Tsunamis” Rarely Leave Their Imprints in the Chromosphere

Solar coronal waves frequently appear as bright disturbances that propagate globally from the eruption center in the solar atmosphere, just like the tsunamis in the ocean on Earth. Theoretically, coronal waves can sweep over the underlying chromosphere and leave an imprint in the form of Moreton wave, due to the enhanced pressure beneath their coronal wave front. Despite the frequent observations of coronal waves, their counterparts in the chromosphere are rarely detected. Why the chromosphere rarely bears the imprints of solar tsunamis remained a mystery since their discovery three decades ago. To resolve this question, all coronal waves and associated Moreton waves in the last decade have been initially surveyed, though the detection of Moreton waves could be hampered by utilizing the low-quality Hα data from the Global Oscillations Network Group. Here, we present eight cases (including five in the Appendix) of the coexistence of coronal and Moreton waves in inclined eruptions where it is argued that the extreme inclination is key to providing an answer to address the question. For all these events, the lowest part of the coronal wave front near the solar surface appears very bright, and the simultaneous disturbances in the solar transition region and the chromosphere predominantly occur beneath the bright segment. Therefore, evidenced by observations, we propose a scenario for the excitation mechanism of the coronal-Moreton waves in highly inclined eruptions, in which the lowest part of a coronal wave can effectively disturb the chromosphere even for a weak (e.g., B-class) solar flare.

Non-native bark beetle species represent a major threat to forest ecosystems. The bark beetle Ips amitinus has recently expanded its range from Finland into northern Sweden. In the present study, we asked the following questions: (i) What is the distribution status in Sweden? (ii) Is there a difference in preference and reproductive success between Norway spruce and Scots pine? (iii) How common is the species after range expansion and does it influence the native community of bark- and wood-boring beetle species?

We established the presence of I. amitinus and co-existence with the native community through checks of logging residues at 382 localities in northern Sweden. In addition, attack densities and reproductive success were compared between spruce and pine through investigating field material and by a no-choice rearing experiment.

We found that I. amitinus is distributed over large parts of northern Sweden. Within its distribution area, it was found in 58% of all checked localities. It is one of the most common bark beetle species in logging residues and a higher proportion of Norway spruce objects compared to Scots pine were colonised. Attack density and reproductive success were higher in Norway spruce in field material and in the rearing experiment. There was no significant difference in the number of native bark- and wood-boring beetle taxa between localities where I. amitinus was present or absent.

The sentinel plantation concept consists of assessing the impact of exotic factors, such as pests and pathogens, on plants of interest by planting them out of their native range. This tool is a way to enhance knowledge for pest risk analysis (PRA) by guiding decisions on how quarantine organisms should be regulated and where to focus prevention and surveillance efforts for an early detection. In this study, the sentinel method was used in the case of research on Xylella fastidiosa, a plant pathogenic bacterium that has recently been found established in southern Europe, but whose potential impact and possible host range are still poorly documented in northern areas where the bacterium is not known to occur. To improve knowledge on the susceptibility of potential hosts of X. fastidiosa in northern Europe, a sentinel plantation of Prunus domestica cv. Opal, Quercus petraea and Salix alba was established in the X. fastidiosa-infected area of Majorca. In order to assess the circulation of the bacterium in the sentinel plot and around it, surveys of the local flora and insect vectors were carried out, as well as the planting of a network of rosemary “spy plants”. Symptomatic monitoring and molecular analyses were performed on the sentinel plants for four years. During these years, X. fastidiosa was never detected in our sentinel plants most likely because of the low infectivity pressure recorded in the surroundings. This study underlines the complexity of conducting sentinel plantation assays combined with X. fastidiosa research, highlighting the need for long-term investigation and questioning the efficiency of the sentinel tool. However, this study is placed in perspective with other valuable sentinel plantations. It also highlights the complementarity of the tool and proposes elements to improve or re-orientate the implementation of future sentinel projects.

The sooty bark disease (SBD) is an emerging disease affecting sycamore maple trees (Acer pseudoplatanus) in Europe. Cryptostroma corticale, the causal agent, putatively native to eastern North America, can be also pathogenic for humans causing pneumonitis. It was first detected in 1945 in Europe, with markedly increasing reports since 2000. Pathogen development appears to be linked to heat waves and drought episodes. Here, we analyse the conditions of the SBD emergence in Europe based on a three-decadal time-series data set. We also assess the suitability of aerobiological samples using a species-specific quantitative PCR assay to inform the epidemiology of C. corticale, through a regional study in France comparing two-year aerobiological and epidemiological data, and a continental study including 12 air samplers from six countries (Czechia, France, Italy, Portugal, Sweden and Switzerland).

We found that an accumulated water deficit in spring and summer lower than -132 mm correlates with SBD outbreaks. Our results suggest that C. corticale is an efficient airborne pathogen which can disperse its conidia as far as 310 km from the site of the closest disease outbreak. Aerobiology of C. corticale followed the SBD distribution in Europe. Pathogen detection was high in countries within the host native area and with longer disease presence, such as France, Switzerland and Czech Republic, and sporadic in Italy, where the pathogen was reported just once. The pathogen was absent in samples from Portugal and Sweden, where the disease has not been reported yet. We conclude that aerobiological surveillance can inform the spatial distribution of the SBD, and contribute to early detection in pathogen-free countries.

Early detection of insect infestation is a key to the adoption of control measures appropriated to each local condition. The use of remote sensing was recommended for a quick scanning of large areas, although it does not work well with signals bearing low intensity or items that are difficult to detect. Unmanned Aerial Vehicle (UAV, or drone) may help in getting closer to individual trees and detect atypical signals of small dimensions. The larvae of the pine processionary moth (PPM, Thaumetopoea pityocampa (Denis & Schiffermüller, 1775, Lepidoptera, Notodontidae) build conspicuous silk nests on the external parts of the host plants at the beginning of the winter and their early detection may prompt managers to adopt management techniques. This work aims at testing two deep learning methods (Region-based Convolutional Neural Network - R-CNN and You Only Look Once - YOLO) to detect the nests under three different conditions of host plant species and forest stands in southern Europe. YOLO algorithm provided better results and it allowed us to achieve F1-scores as high as 0.826 and 0.696 for the detection of presence / absence and the individual nests, respectively. The detection of all the nests that can be present on a tree is not achievable with either UAV scanning or traditional ground observation, therefore the integration of the methods may allow the complete efficiency of the surveillance. The use of UAV combined with Artificial Intelligence (AI) image analysis is recommended for further use in forest and urban settings for the detection of the PPM nests. The recommended methods can be extended to other pest systems, especially when specific symptoms can be associated with an insect pest species.

Background/Aims: A re-increasing trend of thyroid cancer since 2015 has been observed despite a similar examination rate, and the incidence of thyroid cancer among young adults continues to rise.Methods: This study used data from the Korean National Health Insurance Service. Individuals 20–39 years of age who underwent ≥ 4 health checkups from 2009–2013 were enrolled and followed throughout 2019. To quantify the metabolic burden, groups were divided by the number of diagnoses of metabolic syndrome across four consecutive health examinations.Results: Among the study population (n = 1,204,646), 5,929 (0.5%) were diagnosed with thyroid cancer during a follow- up period of 5 years. The hazard ratio (95% confidence interval) values of thyroid cancer occurrence according to the number (1–4) of diagnoses of metabolic syndrome across the four health examinations compared to the group without metabolic syndrome were significantly greater, as follows: 1.12 (1.02–1.23), 1.25 (1.10–1.42), 1.33 (1.15–1.55), and 1.48 (1.25–1.75) (p for trend < 0.01), respectively. Each component of metabolic syndrome showed a significant increase in hazard ratio according to the number of diagnoses except for impaired fasting glucose criteria.Conclusions: Cumulative exposure to metabolic syndrome was associated with thyroid cancer risk in young adults.
