FoMO: Kecemasan Digital di Kalangan Pengguna TikTok
Authors: Darmayanti Dyan Paramitha , Arifin Iqbal , Inayah Muh
Published: January 2024

TikTok is one of the most popular social media today and has even become one of the social media that triggered the emergence of fear of missing out (FoMO) phenomenon. FoMO is a feeling of anxiety, discomfort, and restlessness felt by a person when he/she feels missing out on opportunities, experiences, or even interesting events presented by other TikTok users. While the existing literatures mostly focuse on the psychological aspects of FoMO and the reasons behind its occurrence, a novel contribution of this article is the different levels of FoMO experienced by those who experience it.
Using a qualitative approach, this study was conducted between May 2023 and August 2023. There were ten participants involved in this study who had experienced or were currently experiencing FoMO. They varied in terms of gender (four males and six females) and age (between 18 and 24 years old), status (six university students, two employees and the other two high school students. Data were collected using in-depth interview and observation.
The research shows that FoMO is the fear of something happening and going viral on TikTok, but when someone misses it or experience it, then he/she will feel left behind, which is popularly termed as "not updated". TikTok is very significant in causing FoMO because it contains unlimited content, is presented in a short duration, is easily accessed, so it can stimulate its users to always scroll (up, down, left, right), and poison its users. When they can't control themselves, they become addicted. There are four main levels of FoMO on TikTok: first, mild FoMO which is just a curiosity to participate in viral content; second, moderate FoMO, where users feel anxious about not being able to follow viral content and create a greater desire to engage; third, severe FoMO which can make users feeling stress and trying to always be connected to TikTok, even to the point of interfering with their daily activities; and finally, extreme FoMO which is the most dangerous level of FoMO because they feel trap by excessive FoMO, even to the point of wanting to end their lives. It is argued in this article that what level a person is at depends on how a person controls him/herself over the use of TikTok. Therefore, TikTok users must be careful from the beginning to control themselves, so that this super strong social media does not dominate its users

Published: January 2024

El emprendimiento e innovación se ha convertido en una de las piezas fundamentales para desarrollar la economía de un país, así mismo permite el desenvolvimiento de los individuos en el mercado, por ello la presente investigación tiene como objetivo general analizar de qué manera el emprendimiento e innovación aporta a la creación de valor en la producción de los pescadores artesanales de la parroquia Salango, cantón Puerto López cuya problemática radica en que los individuos durante el tiempo de su actividad solo se han dedicado a extraer la producción pesquera del mar, es decir que no aplican proceso de producción innovador antes de venderla, lo que imposibilita la entrada de mayores ingresos y adaptación de nuevas actualizaciones que nacen en el mercado empresarial. La metodología utilizada es de enfoque cualitativa y cuantitativa, misma que se sustentó en los métodos siguientes; inductivo, bibliográfico, analítico-sintético y el estadístico, técnica como las encuestas aplicadas a los 250 pescadores artesanales (muestra); en conjunto a las herramientas del Análisis FODA y PESTEL se recopilo información de gran importancia. Entre los resultados obtenidos se determinó que los pescadores artesanales poseen niveles bajos de preparación educativa, carencia de conocimientos en temas de emprendimiento e innovación, limitado acceso a líneas de créditos y la poca aplicabilidad de procesos innovadores. Por tales motivos, se concluye que las autoridades del GAD parroquial deben invertir en capacitaciones de temas productivos, permitiendo así el desarrollo del espíritu emprendedor del pescador y sobre invertir en alternativas de valor que potencialicen sus recursos pesqueros.

Ensino de Botânica: uma proposta contextualizada a partir das plantas ornamentais tóxicas
Authors: De Souza Luciano Tavares , Silva Roberta Dos Santos
Published: January 2024

O ensino de botânica na educação básica tem se caracterizado como conteudista, enfadonho e desinteressante. Um dos fatores que contribuem para esse distanciamento do conteúdo está na dificuldade do estudante em lidar com uma série de termos complexos de difícil compreensão e sem aproximação com seu contexto de vivência. Nesse cenário, o professor é desafiado a utilizar diferentes estratégias de ensino que contribuam para a aprendizagem dos conceitos/conteúdos botânicos para os estudantes. Esta pesquisa teve como principal objetivo analisar, no âmbito de uma disciplina eletiva, as potencialidades de diferentes estratégias de ensino para contextualização dos conceitos/conteúdos botânicos. A disciplina eletiva intitulada “O jardim secreto” foi desenvolvida no Centro de Ensino Médio Paulo Freire com vinte estudantes, com idades entre 14 e 18 anos, que estavam regularmente matriculados na instituição de ensino. Elaborou-se uma sequência didática que foi avaliada conforme dados de quatro instrumentos: observação, questionários investigativos, materiais didáticos produzidos e descrição direta. Tais abordagens, como o detalhamento dos momentos das aulas e as estratégias utilizadas na sequência, foram significativamente positivas para o aprendizado dos estudantes. “O jardim secreto” confirmou a hipótese de que as diferentes estratégias utilizadas podem diversificar, aprofundar e enriquecer, de forma contextualizada, os conteúdos trabalhados pela Base Nacional Comum Curricular (BNCC) e legitimar os resultados que corroboram a validação dos objetivos previstos, contribuindo para a formação de estudantes mais conscientes, críticos e cidadãos.

O objetivo deste trabalho foi avaliar o desempenho agronômico de milho variedade em dois sistemas de manejo do solo e níveis de adubação fosfatada em um Latossolo Amarelo distrófico típico (textura arenosa) no município de Mâncio Lima (AC). O trabalho foi realizado no município mencionado, numa área de Latossolo Amarelo distrófico típico (textura arenosa) em estádio de degradação agrícola. O delineamento experimental adotado foi o de blocos casualizados no esquema de parcelas subdivididas, com quatro repetições. Os tratamentos na parcela consistiram em dois sistemas de manejo do solo: cultivo convencional (CC) e cultivo mínimo (CM). Os tratamentos na subparcela consistiram em quatro níveis de adubação fosfatada: Tratamento 1 (P1) = 40 kg ha-1 de P2O5; Tratamento 2 (P2) = 80 kg ha-1 de P2O5; Tratamento 3 (P3) = 120 kg ha-1 de P2O5; Tratamento 4 (P4) = 160 kg ha-1 de P2O5. Foram avaliadas variáveis morfológicas e de produção. Os dados observados foram submetidos ao teste F (p<0,05). Para os tratamentos qualitativos, as médias foram comparadas pelo teste de Tukey (p<0,05), e para os tratamentos quantitativos foi realizada análise de regressão. O manejo do solo influencia a produção de matéria seca, o diâmetro do colmo e a altura de inserção da espiga, que são maiores no sistema de manejo convencional. Nas condições edafoclimáticas em que este trabalho foi desenvolvido, a produtividade de grãos aumentou linearmente em função da adubação fosfatada até a dose de 160 kg ha-1 de P2O5, independentemente do sistema de manejo do solo.

Authors: Kunzler Bruna Eduarda , Pimentel Leidiane Reis , Souza Jane Pimentel
Published: January 2024

O ovo está entre os alimentos mais consumidos em todo o mundo, principalmente devido ao fácil acesso e baixo custo. No Brasil, a refrigeração de ovos comercializados não é obrigatória, de modo que os ovos ficam acondicionados em temperatura ambiente, o que pode afetar sua qualidade, com o tempo prolongado de armazenamento, sobretudo em localidades de clima quente. Diante disso, objetivou-se avaliar a qualidade de ovos comercializados em quatro supermercados do município de Dianópolis, estado do Tocantins (TO), entre os meses de julho a dezembro de 2022. Selecionaram-se quatro supermercados do município e foram adquiridas 6 bandejas, cada uma com 12 ovos, sendo 1 bandeja por supermercado/mês. Os ovos coletados foram enumerados e seguiram para um exame criterioso da casca, buscando-se eventuais defeitos de formação, trincamentos e sujidades aderidas. Na sequência, houve a mensuração do peso dos ovos, para que pudessem ser classificados posteriormente. Para a determinação dos índices de gema, albúmen e unidade Haugh, os ovos foram quebrados e seus componentes foram pesados separadamente. Considerando-se os quatro supermercados analisados, os comércios S3 e S4 apresentaram os piores resultados para qualidade interna, além de péssimas condições de armazenamento, enquanto ovos oriundos dos supermercados maiores (S1 e S2) apresentaram qualidade interna superior. De maneira geral, pode-se considerar que os ovos comercializados no município de Dianópolis (TO) demonstram altos índices de defeitos externos bem como baixa qualidade interna, apresentando valores de unidade Haugh inferiores ao preconizado pelo Departamento de Agricultura Americano, que garante que ovos de qualidade devem apresentar unidade Haugh superior a 60.

In family life, pets have become a very important member, as various global events lead society towards isolation, and new technologies encourage increasingly less personalized communication. The need for companionship that humanizes these changes becomes evident.
In this context, pets are now considered as another family member, and as a result, they should be assigned and provided with appropriate conditions. The mere thought or concept of permanent loss or the possibility of one of them getting lost is a very painful scenario.
Based on the above, this research aims to mitigate such effects to a large extent. The project includes three components that allow the pet owner to have more effective control over their pet: a GPS collar, QR code, and a mobile app. The GPS collar enables the owner to know the pet's location, the QR code provides information such as the pet's name, age, breed, and photo, along with the owner's name and contact phone number. The mobile app serves as a tool that allows the owner to monitor the pet's location from their phone.

Effectiveness of a Driving and Community Mobility Intervention for Teens and Young Adults With Autism Spectrum Disorder
Authors: Dickerson Anne E. , Turbeville Lauren , Wu Qiang
Published: January 2024

Importance: Driving and community mobility (DCM) is key to supporting independence in teens and young adults (TYA) with autism spectrum disorder (ASD).

Objective: To determine whether an intervention focused on DCM can effectively improve DCM knowledge and skills in TYA.

Design: A pretest–posttest design using the same intervention and outcome measures.

Setting: University research setting.

Participants: Thirty-eight participants with ASD completed the program (M age = 17.76 yr, SD = 3.58). Twenty-six (68%) were male, and 12 (32%) were female.

Intervention: A 5-day intensive intervention using group and individualized strategies, including driving simulation, focused on improving performance skills needed for DCM.

Outcome and Measures: Total and category scores of the Performance Analysis of Driving Ability (P-Drive) were analyzed using a repeated-measures analysis of variance measuring time (pretest vs. posttest), gender, and year of intervention. Paired t tests were used to determine the outcomes of the Canadian Occupational Performance Measure (COPM), anxiety measure and perception survey.

Results: Results indicated a significant main effect for time (p < .001) and year (p < .036), but not gender (p < .26), with no significant interaction effects, supporting the fidelity of the intervention. The COPM showed significant changes (p ≤ .001) in both performance and satisfaction, as well as a reduction in anxiety (p = .008).

Conclusions and Relevance: Outcomes suggest that the intervention successfully improved DCM knowledge and skills for TYA. This adds new evidence that an occupational therapy intervention specific to TYA with ASD is effective in developing independence in DCM.

Plain-Language Summary: Driving is the primary mode of community mobility in North America and other Western countries. Adults with autism spectrum disorder (ASD) who have a means of community mobility have a chance of employment that is 5 times greater than that for those who do not. Driving and community mobility are key to supporting independence among teens and young adults with ASD. However, teens and young adults with ASD have significantly lower rates of getting a driver’s license. The results of this study show that occupational therapy practitioners can play a critical role in addressing driving and community mobility. Occupational therapy interventions that are specifically designed for and unique to each teen and young adult with ASD can effectively improve driving and community mobility skills and increase independence.

A Decision Cloud Ranking Approach Based on Privacy and Security in Blockchain E-Health Industry 4.0 Systems
Authors: Qahtan Sarah , Yatim Khaironi , Osman Mohd Hafeez , Zulzalil Hazura , Muhammad Luqman Mahamad Zakaria
Published: January 2024

E-health Industry 4.0 systems ranking based on Blockchain is a multi-criteria decision-making (MCDM) problem, considering the multiple evaluation properties, their significance, and data variety. The final closeness between the evaluation sample and ideal solutions also constitutes an optimisation problem. To the authors’ knowledge, no study has provided a multi-privacy and security ranking approach solution for E-health Industry 4.0 systems based on Blockchain. Consequently, this study proposes and discusses a multi-privacy and security ranking approach solution for E-health Industry 4.0 systems, utilising the SFS-FWZIC method to address the significance of properties issue and the Grey-TOPSIS method to tackle data variation, multiple evaluation properties, and the ideal solutions optimisation problem. The methodology of the proposed approach consists of three sections. First, three decision matrices are constructed based on the intersection of E-health systems with the mentioned properties, intersecting Electronic Health Records (EHRs), Electronic Medical Records (EMRs), and Personal Health Records (PHRs) with seven properties. Second, the weights of each privacy and security property are calculated using the SFS-FWZIC method. Finally, the weights determined by the SFS-FWZIC method and the three decision matrices are input into the Grey-TOPSIS method to rank E-health systems across the three categories. The findings reveal the following: (1) The SFS-FWZIC method effectively assigned weights to privacy and security properties, with access control achieving the highest significance weight (0.1934) and Secure-search receiving the lowest weight (0.0603). (2) The Grey-TOPSIS method efficiently ranked E-health systems across the three categories based on various parameters, including α=0.1,α=0.3,α=0.5,α=0.7, and α=0.9. Sensitivity and correlation analysis were conducted to evaluate the results, revealing high correlation results based on each α value across all discussed scenarios of changing property weights. The implications of this study can lead to better decision-making, improved security and privacy, increased competition, and widespread adoption, ultimately contributing to more efficient and effective healthcare delivery.

Penelitian terhadap kecukupan sumber air mentah merupakan satu aspek yang penting dalam memastikan kesejahteraan kehidupan masyarakat yang berterusan. Sistem penuaian juga merupakan satu altenatif yang disarankan sebagai langkah untuk memastikan terdapat takungan bekalan air mentah bagi kegunaan masyarakat sama ada bagi kegunaan luaran mahupun kegunaan dalaman ketika bekalan air terawat terhenti. Sehubungan itu, bekalan air tuaian hujan yang berkualiti perlu diberikan perhatian. Air tuaian hujan dapat ditafsirkan sebagai air hujan yang dikumpul dan ditadah dalam sesuatu bekas untuk kegunaan luaran seperti membasuh dan penyiraman tanaman. Namun, pembangunan secara tidak seimbang yang berlaku pada masa kini telah memberikan impak yang besar terhadap tahap kualiti air tuaian hujan yang akan merugikan bukan sahaja kepada masyarakat tetapi juga negara untuk jangka masa panjang. Kajian lepas menunjukkan wujud keperluan untuk mengkaji dan meneliti tahap kualiti air tuaian hujan bagi menentukan tahap kesesuaian air hujan ini sebelum boleh digunakan. Oleh itu, kajian ini dilaksanakan dengan tujuan untuk meneliti dan menilai tahap kualiti air tuaian hujan berdasarkan kepada Indeks Kualiti Air (IKA) yang dikeluarkan oleh Jabatan Alam Sekitar bagi kawasan Cameron Highlands, Pahang. Parameter kualiti air iaitu NH³N, BOD dan beberapa parameter Logam Berat (Cd, Pb, Fe, dan Mn) digunakan dalam analisis ini. Kajian ini telah menggunakan dua kaedah utama iaitu dengan mengambil sampel air hujan di tiga kawasan berbeza di kawasan kajian iaitu kawasan bandar, penempatan, dan pertanian. Kedua, tinjauan dan soal selidik telah dijalankan dengan melibatkan 70 orang responden yang terdiri daripada masyarakat setempat. Analisis parameter kualiti air bagi NH³N mendapati kesemua sampel air hujan yang diambil pada musim lembap sememangnya tidak selamat digunakan kerana kandungan NHзN yang sangat tinggi (>1.5mg/l) berbanding sampel yang diambil pada musim kering. Bagi analisis BOD pula, mendapati tahap kandungan BOD dalam sampel air adalah tinggi dan tidak sesuai digunakan sebagai sumber air minuman pada kedua-dua musim (>6 mg/l).  Manakala, hasil analisis terhadap persepsi masyarakat berkaitan kualiti air hujan mendapati penduduk setempat bersetuju dengan pembangunan yang tidak seimbang mampu menjejaskan kualiti air hujan. Justeru itu, pembangunan yang terkawal dan dirancang mampu membantu untuk memastikan air tuaian hujan pada masa akan datang akan lebih berkualiti.
PENTAKRIFAN “RITUAL AMPARAWAK” DI KALANGAN MASYARAKAT MURUT TAHOL DI SABAH: SOROTAN LITERATUR
Authors: Rosly Rozaliza
Published: January 2024

Perbincangan berkaitan “ritual amparawak” ini sudah pernah dibahaskan dalam kajian-kajian terdahulu dalam kalangan ahli akademik. Walaubagaimanapun, kebanyakan kajian yang membincangkan mengenai “ritual amparawak” terus menjelaskannya secara spesifik berdasarkan kepada jenis aktiviti tanpa mendalami maksud amparawak secara umum menyebabkan penjelasan mengenai ritual ini agak sukar untuk dibahas secara umum tanpa sokongan daripada jenis aktiviti yang menyelitkan ritual ini. Tambahan pula,  upacara mahupun aktiviti yang menyelitkan ritual amparawak ini diamalkan bukan sahaja masyarakat Murut Tahol yang tinggal di daerah Nabawan tetapi juga di daerah lain seperti daerah Tenom. Perbezaan dari segi nama ritual dan cara pelaksanaan yang ditonjolkan oleh masyarakat Murut yang tinggal di kawasan berbeza ini menambahkan lagi kesukaran dalam mencari tahu definisi bagi amparawak. Sehubungan dengan itu, kajian ini akan menjalankan sorotan literatur terhadap penulisan-penulisan berkaitan ”ritual amparawak” dan mengklasifikasikan semula pendefinisian ritual amparawak. Hasil dapatan kajian menunjukkan definisi amparawak ialah satu perbuatan mencalitkan darah binatang ”smearing animal blood” sama ada pada anggota badan, harta benda mahupun tumbuh-tumbuhan dan ritual ini bertujuan untuk menenangkan dunia spiritual dan inaning masyarakat Murut Tahol. Dengan ritual ini tentunya diharapkan oleh masyarakat Murut Tahol agar terlindung daripada sesuatu perkara yang buruk berbentuk musibah seperti kemalangan, penyakit, hasil tanaman yang tidak menjadi yang menyebabkan kepada kebuluran. Musibah ini dipercayai oleh masyarakat Murut Tahol sebagai kesan daripada bentuk kemarahan dunia spiritual akibat daripada pelanggaran adat yang telah ditetapkan oleh masyarakat ini.

Anak merupakan sumber daya yang sangat penting bagi masa depan sebagai generasi penerus bangsa. Anak yang dilahirkan di luar kawin dapat diubah statusnya menjadi anak sah dari suatu perkawinan yang telah diakui oleh negara. Pembuatan akta kelahiran anak merupakan salah satu cara memberikan status hukum bagi anak. Anak haram dapat diperlakukan sebagai anak sah melalui proses hukum yang dikenal dengan istilah “legalisasi” (rechts middle). Penelitian ini ditujukan untuk memberi kepastian hukum terhadap status anak. Dengan menggunakan tipologi riset hukum normatif dengan pendekatan perundang-undangan, digunakan data sekunder yang berasal dari sumber hukum primer, sekunder, dan tersier. Untuk memberikan analisis deskriptif, proses berpikir formal dan argumentatif, serta kesimpulan, selanjutnya proses pengumpulan data diolah dengan menggunakan pendekatan kualitatif. Untuk tertib andministrasi kependudukan maka diperlukan dan pencatatan secara resmi oleh Dinas Kependudukan dan Catatan Sipil setempat. Selain itu, permintaan validasi dapat diajukan melalui perintah pengadilan daerah. Hak-hak sipil anak  harus dilindungi oleh orang tuanya, masyarakat dan dengan diakui secara hukum sebagai keturunannya yang sah.

Tipologi penelitian hukum normatif digunakan bersama dengan pendekatan perundang-undangan, dan sumber data sekunder berupa teks hukum primer, sekunder, dan tersier digunakan sebagai sumber datanya. Pendekatan kualitatif digunakan untuk mengolah pendekatan pengumpulan data. Analisis deskriptif dan strategi penalaran formal dan argumentatif digunakan untuk menarik temuan. Temuan penelitian mengungkapkan bahwa LKSA bertugas mendaftarkan tanda pengenal anak pada instansi terkait. Apabila LKSA tidak menjunjung tinggi hak identifikasi anak, terdapat sanksi administratif.
Time-Varying Seismogenic Coulomb Electric Fields as a Probable Source for Pre-Earthquake Variation in the Ionospheric F2-Layer
Authors: Kim Vitaly P. , Hegai Valery V. , Liu Jann Yenq , Ryu Kwangsun , Chung Jong-Kyun
Published: January 2024

The electric coupling between the lithosphere and the ionosphere is examined. The electric field is considered as a timevarying irregular vertical Coulomb field presumably produced on the Earth’s surface before an earthquake within its epicentral zone by some micro-processes in the lithosphere. It is shown that the Fourier component of this electric field with a frequency of 500 Hz and a horizontal scale-size of 100 km produces in the nighttime ionosphere of high and middle latitudes a transverse electric field with a magnitude of ~20 mV/m if the peak value of the amplitude of this Fourier component is just 30 V/m. The time-varying vertical Coulomb field with a frequency of 500 Hz penetrates from the ground into the ionosphere by a factor of ~7×105 more efficient than a time independent vertical electrostatic field of the same scale size. The transverse electric field with amplitude of 20 mV/m will cause perturbations in the nighttime F region electron density through heating the F region plasma resulting in a reduction of the downward plasma flux from the protonosphere and an excitation of acoustic gravity waves.
A Study on Re-entry Predictions of Uncontrolled Space Objects for Space Situational Awareness
Authors: Choi Eun-Jung , Cho Sungki , Lee Deok-Jin , Kim Siwoo , Jo Jung Hyun
Published: January 2024

The key risk analysis technologies for the re-entry of space objects into Earth’s atmosphere are divided into four categories: cataloguing and databases of the re-entry of space objects, lifetime and re-entry trajectory predictions, break-up models after re-entry and multiple debris distribution predictions, and ground impact probability models. In this study, we focused on reentry prediction, including orbital lifetime assessments, for space situational awareness systems. Re-entry predictions are very difficult and are affected by various sources of uncertainty. In particular, during uncontrolled re-entry, large spacecraft may break into several pieces of debris, and the surviving fragments can be a significant hazard for persons and properties on the ground. In recent years, specific methods and procedures have been developed to provide clear information for predicting and analyzing the re-entry of space objects and for ground-risk assessments. Representative tools include object reentry survival analysis tool (ORSAT) and debris assessment software (DAS) developed by National Aeronautics and Space Administration (NASA), spacecraft atmospheric re-entry and aerothermal break-up (SCARAB) and debris risk assessment and mitigation analysis (DRAMA) developed by European Space Agency (ESA), and semi-analytic tool for end of life analysis (STELA) developed by Centre National d’Etudes Spatiales (CNES). In this study, various surveys of existing re-entry space objects are reviewed, and an efficient re-entry prediction technique is suggested based on STELA, the life-cycle analysis tool for satellites, and DRAMA, a re-entry analysis tool. To verify the proposed method, the re-entry of the Tiangong-1 Space Lab, which is expected to re-enter Earth’s atmosphere shortly, was simulated. Eventually, these results will provide a basis for space situational awareness risk analyses of the re-entry of space objects.

Halo coronal mass ejections (CMEs) originating from solar activities give rise to geomagnetic storms when they reach the Earth. Variations in the geomagnetic field during a geomagnetic storm can damage satellites, communication systems, electrical power grids, and power systems, and induce currents. Therefore, automated techniques for detecting and analyzing halo CMEs have been eliciting increasing attention for the monitoring and prediction of the space weather environment. In this study, we developed an algorithm to sense and detect halo CMEs using large angle and spectrometric coronagraph (LASCO) C3 coronagraph images from the solar and heliospheric observatory (SOHO) satellite. In addition, we developed an image processing technique to derive the morphological and dynamical characteristics of halo CMEs, namely, the source location, width, actual CME speed, and arrival time at a 21.5 solar radius. The proposed halo CME automatic analysis model was validated using a model of the past three halo CME events. As a result, a solar event that occurred at 03:38 UT on Mar. 23, 2014 was predicted to arrive at Earth at 23:00 UT on Mar. 25, whereas the actual arrival time was at 04:30 UT on Mar. 26, which is a difference of 5 hr and 30 min. In addition, a solar event that occurred at 12:55 UT on Apr. 18, 2014 was estimated to arrive at Earth at 16:00 UT on Apr. 20, which is 4 hr ahead of the actual arrival time of 20:00 UT on the same day. However, the estimation error was reduced significantly compared to the ENLIL model. As a further study, the model will be applied to many more events for validation and testing, and after such tests are completed, on-line service will be provided at the Korean Space Weather Center to detect halo CMEs and derive the model parameters.

Published: January 2024

Higgs boson enables the Standard Model (SM) to be established. However, we do not know much about dark matter which occupies approximately six times of the SM particles in universe besides having mass. The interactions of dark matter is much weaker than that of the SM. Further, its mass range is very wide, from the order of eV to PeV. Therefore, many experiments have contributed to search for dark matter by indirect, direct and accelerator research. This paper reviews researches on dark matter using accelerator, especially the e+ e− collider, from the viewpoint of experimental high energy physicists.
Application of a Coupled Harmonic Oscillator Model to Solar Activity and El Niño Phenomena
Authors: Muraki Yasushi
Published: January 2024

Solar activity has an important impact not only on the intensity of cosmic rays but also on the environment of Earth. In the present paper, a coupled oscillator model is proposed to explain solar activity. This model can be used to naturally reduce the 89-year Gleissberg cycle. Furthermore, as an application of the coupled oscillator model, we herein attempt to apply the proposed model to El Niño-southern oscillation (ENSO). As a result, the 22-year oscillation of the Pacific Ocean is naturally explained. Finally, we search for a possible explanation for coupled oscillators in actual solar activity.
X-ray Data Analysis to Search for Magnetar Candidates in the Galactic Plane
Authors: Park Woochan , An Hongjun
Published: January 2024

We report on our Galactic plane searches for magnetars in the archival Chandra X-ray Observatory (CXO) data. We summarize the properties of known magnetars and use them to establish a procedure for magnetar searches. The procedure includes four steps: source finding, spectral characterization, optical counterpart checks, and period searches. We searched 1,282 archival CXO observations, found 32,838 X-ray sources, and selected 25 intriguing candidates using the developed procedure. Although we do not firmly identify a magnetar among them, we significantly reduced the number of targets in future magnetar searches to be done with better X-ray telescopes.
Satellite-based In-situ Monitoring of Space Weather: KSEM Mission and Data Application
Authors: Oh Daehyeon , Kim Jiyoung , Lee Hyesook , Jang Kun-Il
Published: January 2024

Many recent satellites have mission periods longer than 10 years; thus, satellite-based local space weather monitoring is becoming more important than ever. This article describes the instruments and data applications of the Korea Space wEather Monitor (KSEM), which is a space weather payload of the GeoKompsat-2A (GK-2A) geostationary satellite. The KSEM payload consists of energetic particle detectors, magnetometers, and a satellite charging monitor. KSEM will provide accurate measurements of the energetic particle flux and three-axis magnetic field, which are the most essential elements of space weather events, and use sensors and external data such as GOES and DSCOVR to provide five essential space weather products. The longitude of GK-2A is 128.2° E, while those of the GOES satellite series are 75° W and 135° W. Multi-satellite measurements of a wide distribution of geostationary equatorial orbits by KSEM/GK-2A and other satellites will enable the development, improvement, and verification of new space weather forecasting models. KSEM employs a service-oriented magnetometer designed by ESA to reduce magnetic noise from the satellite in real time with a very short boom (1 m), which demonstrates that a satellite-based magnetometer can be made simpler and more convenient without losing any performance.
Solar Cyclic Modulation of Diurnal Variation in Cosmic Ray Intensity

Published: January 2024

Cosmic rays are ions that move at relativistic speeds. They generate secondary cosmic rays by successive collisions with atmospheric particles, and then, the secondary particles reach the ground. The secondary particles are mainly neutrons and muons, and the neutrons are observed by the ground neutron monitor. This study compared the diurnal variation in cosmic ray intensity obtained via harmonic analysis and that obtained through the pile-up method, which was examined in a previous study. In addition, we analyzed the maximum phase of the diurnal variation using four neutron monitors with a cutoff rigidity below approximately 6 GV, located at similar longitudes to the Oulu and Rome neutron monitors. Expanding the data of solar cycles 20–24, we examined the time of the maximum cosmic ray intensity, that is, the maximum phase regarding the solar cyclic modulation. During solar cycles 20–24, the maximum phase derived by harmonic analysis showed no significant difference with that derived by the pile-up method. Thus, the pile-up method, a relatively straightforward process to analyze diurnal variation, could replace the complex harmonic analysis. In addition, the maximum phase at six neutron monitors shows the 22-year cyclic variation very clearly. The maximum phase tends to appear earlier and increase the width of the variation in solar cycles as the cutoff rigidity increases.

Published: January 2024

This study presents the generation and accuracy assessment of predicted orbital ephemeris based on satellite laser ranging (SLR) for geostationary Earth orbit (GEO) satellites. Two GEO satellites are considered: GEO-Korea Multi-Purpose Satellite (KOMPSAT)-2B (GK-2B) for simulational validation and Compass-G1 for real-world quality assessment. SLR-based orbit determination (OD) is proactively performed to generate orbital ephemeris. The length and the gap of the predicted orbital ephemeris were set by considering the consolidated prediction format (CPF). The resultant predicted ephemeris of GK-2B is directly compared with a pre-specified true orbit to show 17.461 m and 23.978 m, in 3D root-mean-square (RMS) position error and maximum position error for one day, respectively. The predicted ephemeris of Compass-G1 is overlapped with the Global Navigation Satellite System (GNSS) final orbit from the GeoForschungsZentrum (GFZ) analysis center (AC) to yield 36.760 m in 3D RMS position differences. It is also compared with the CPF orbit from the International Laser Ranging Service (ILRS) to present 109.888 m in 3D RMS position differences. These results imply that SLR-based orbital ephemeris can be an alternative candidate for improving the accuracy of commonly used radar-based orbital ephemeris for GEO satellites.

Radar sensors are used for space situational awareness (SSA) to determine collision risk and detect re-entry of space objects. The capability of SSA radar system includes radar sensitivity such as the detectable radar cross-section as a function of range and tracking capability to indicate tracking time and measurement errors. The time duration of the target staying in a range cell is short; therefore, the signal-to-noise ratio cannot be improved through the pulse integration method used in pulse-Doppler signal processing. In this study, a method of improving the signal-to-noise ratio during range migration is presented. The improved detection performance from signal processing gains realized in this study can be used as a basis for comprehensively designing an SSA radar system.
