Authors: Halimah  , Surya Agustian  , Siti Ramadhani  
Published: December 2022

Artikel merupakan kumpulan teks atau kalimat yang panjang dan berisikan gagasan atau pendapat terhadap suatu topik tertentu. Artikel yang sangat panjang akan menghabiskan waktu cukup lama untuk membaca dan memahami poin-poin penting yang disampaikan. Penelitian ini mengusulkan algoritma Lexrank untuk meringkas teks otomatis pada artikel berbahasa indonesia. Penelitian ini menggunakan dataset berupa korpus yang tersusun atas 300 artikel dari berbagai topik. Kalimat yang dipilih menjadi ringkasan untuk gold standard dirata-ratakan dari dua orang annotator. Metode peringkas dokumen dikembangkan untuk menghasilkan ringkasan yang performanya dibandingkan dengan gold standard tersebut menggunakan ROUGE score. Metode bekerja dengan beberapa tahap, mulai dari text preprocessing yang meliputi segmentasi kalimat, case folding, tokenisasi, punctuation removal, stemming dan stopword removal. Kemudian menghitung bobot tf-idf, bobot similarity, pembentukan graf, pemeringkatan kalimat, dan tahap akhir adalah membentuk hasil ringkasan. Untuk pengembangan sistem, 150 dokumen diuji coba dengan variasi pemilihan ranking similarity, dan yang terbaik digunakan sebagai model untuk test document. Hasil pengujian dengan compression rate 50% menghasilkan nilai f-measure rata-rata untuk 150 test document, pada metrik ROUGE-1, ROUGE-2 dan ROUGE-L secara berturut-turut adalah 67,53%, 59,10%, dan 67,05%. Sedangkan untuk compression rate 30% menghasilkan rata-rata f-measure pada ROUGE-1, ROUGE-2 dan ROUGE-L secara berturut-turut adalah 55,82%, 45,51%, dan 54,76%. Penelitian ini menghasilkan akurasi f-measure yang lebih baik dan kompetitif bila merujuk pada hasil-hasil penelitian sejenis.

Abstract
We report a revised analysis for the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J0740+6620, studied previously with joint fits to NICER and XMM-Newton data by Riley et al. (2021) and Miller et al. (2021). We perform a similar Bayesian estimation for the pulse-profile model parameters, except that instead of fitting simultaneously the XMM-Newton data, we use the best available NICER background estimates to constrain the number of photons detected from the source. This approach eliminates any potential issues in the cross-calibration between these two instruments, providing thus an independent check of the robustness of the analysis. The obtained neutron star parameter constraints are compatible with the already published results, with a slight dependence on how conservative the imposed background limits are. A tighter lower limit causes the inferred radius to increase, and a tighter upper limit causes it to decrease. We also extend the study of the inferred emission geometry to examine the degree of deviation from antipodality of the hot regions. We show that there is a significant offset to an antipodal spot configuration, mainly due to the non-half-cycle azimuthal separation of the two emitting spots. The offset angle from the antipode is inferred to be above 25° with 84% probability. This seems to exclude a centered-dipolar magnetic field in PSR J0740+6620.

Abstract
The discovery and spectroscopic confirmation of Hyperion, a protosupercluster at z ∼ 2.47, provides an unprecedented opportunity to study distant galaxies in the context of their large-scale environment. We carry out deep narrowband imaging of a ≈1° × 1° region around Hyperion and select 157 Lyα emitters (LAEs). The inferred LAE overdensity is δ

g
≈ 40 within an effective volume of 30 × 20 × 15 cMpc3, consistent with the fact that Hyperion is composed of multiple protoclusters and will evolve into a supercluster with a total mass of M
tot ≈ 1.4 × 1015
M
⊙ at z = 0. The distribution of LAEs closely mirrors that of known spectroscopic members, tracing the protocluster cores and extended filamentary arms connected to them, suggesting that they trace the same large-scale structure. By cross-correlating the LAE positions with H i tomography data, we find weak evidence that LAEs may be less abundant in the highest H i regions, perhaps because Lyα is suppressed in such regions. The Hyperion region hosts a large population of active galactic nuclei (AGNs) ≈ 12 times more abundant than that in the field. The prevalence of AGNs in protocluster regions hints at the possibility that they may be triggered by physical processes that occur more frequently in dense environments, such as galaxy mergers. Our study demonstrates LAEs as reliable markers of the largest cosmic structures. When combined with ongoing and upcoming imaging and spectroscopic surveys, wide-field narrowband imaging has the potential to advance our knowledge in the formation and evolution of cosmic structures and of their galaxy inhabitants.

Abstract
Observational studies of the innermost regions of the edge-on jets in nearby active galactic nuclei (AGN) are crucial to understanding their kinematics and morphology. For the inner jet of the nearby low-luminosity AGN in M84, we present new high-sensitivity observations with very long baseline Interferometry since 2019, as well as archival Very Long Baseline Array observations in 2014. We find that the compact core in M84 has an inverted-to-flat spectrum from 1.5–88 GHz. Based on the turnover frequency of 4.2 ± 0.2 GHz in the spectrum, we estimated a magnetic field strength of 1 ∼ 10 mG and an electron number density of ∼105 cm−3 in the core region. Three inner jet components within ∼3 mas of the core are identified and traced in the images at 22 GHz, whose apparent speeds are 0.11 c, 0.27 c, and 0.32 c, respectively. We calculate the viewing angle of

for the inner jet based on the proper motion and the flux ratio of jet to counterjet. A propagating sinusoidal model with a wavelength of ∼3.4 mas is used to fit the helical morphology of the jet extended to 20 mas (∼2.2 × 104 Schwarzschild radii).

Published: December 2022

Abstract
Coronal mass ejections (CMEs) are the largest type of eruptions on the Sun and the main driver of severe space weather at the Earth. In this study, we implement a force-free spheromak CME description within 3D magnetohydrodynamic simulations to parametrically evaluate successive interacting CMEs within a representative heliosphere. We explore CME–CME interactions for a range of orientations, launch time variations, and CME handedness and quantify their geo-effectiveness via the primary solar wind variables and empirical measures of the disturbance storm time index and subsolar magnetopause standoff distance. We show how the interaction of two moderate CMEs between the Sun and the Earth can translate into extreme conditions at the Earth and how CME–CME interactions at different radial distances can maximize different solar wind variables that induce different geophysical impacts. In particular, we demonstrate how the orientation and handedness of a given CME can have a significant impact on the conservation and loss of magnetic flux, and consequently B

, due to magnetic reconnection with the interplanetary magnetic field. This study thus implicates the identification of CME chirality in the solar corona as an early diagnostic for forecasting geomagnetic storms involving multiple CMEs.

Published: December 2022

Lysiteles Simon, 1895 is one of the largest taxa with small body size among the Thomisidae and is mainly distributed in East, South and Southeast Asia. Most of them are recorded from southern provinces of China, such as Jiangxi Province, including three species. However, all of them are only discovered from Jinggang Mountain National Nature Reserve in Jiangxi Province. But there are still other species remaining unknown which need to be surveyed from other areas in this Province.
One Lysiteles species was collected from Nanfengmian National Nature Reserve in Jiangxi Province. Based on morphological characters, it was recognised as a new species and has been named as Lysiteles nanfengmian sp. n. It is described and illustrated with photographs and its distribution is also mapped.
Pratique « freinetique » de l’équipe
Authors: Perrier Edmond 
Published: December 2022

L’auteur témoigne de son expérience d’école primaire dans une classe « Freinet » Il décrit les pratiques de travail en équipe et les ateliers. Il met en rapport ces manières de faire avec les pratiques qu’il a découvertes, jeune interne, en assistant aux journées de psychothérapie institutionnelle à Saint-Alban. L’importance de l’équipe et du collectif est mise à mal aujourd’hui par l’idéologie gestionnaire. Ce discours dominant ne peut se déployer que dans une organisation hiérarchisée, quantifiée, pesée, évaluée qui brise les solidarités et pousse beaucoup au retrait de l’engagement. Malgré tout, des lieux subsistent où le travail en équipe résiste et s’avère toujours fécond
Correlation between the Clinical, Etiological, Radiological, and Histopathological Pattern in Patients of Interstitial Lung Disease
Authors: Jain Anuj , Sharma Vishal , Pasha Mohammed Mahaboob , Subramanian Narayanan , Prasad Vishnu , Kotaru Arun Chowdary 
Published: December 2022

Abstract

Background and Objective:
Interstitial lung diseases (ILDs) include a large number of conditions that primarily involve space between the alveolar epithelium, the capillary endothelium, and adjoining structures such as alveoli and small airways. This study has been conceived to generate the data on the clinical, etiological, radiological, and histopathological pattern of patients of ILD.

Methods:
This prospective study was conducted from January 1, 2018 to October 31, 2019 enrolling 43 patients of ILD who presented as outpatient/in patients to a tertiary care hospital in North India. Based on the clinical presentation and chest X-ray, the suspected patients were subjected to high-resolution computerised tomography (HRCT) chest and pulmonary function test for confirmation. The confirmed cases were then subjected to bronchoscopy and histopathological study.

Results:
There were 26 (60%) male patients and 17 (40%) female patients in the study population. The mean (±standard deviation) age was 56.9 ± 13.02 years. A diagnosis of ILD was made based on the history and clinical findings in 35 (81.5%) cases. The most common finding on chest radiography was reticular opacities in 20 (46%). Usual interstitial pneumonia pattern 20 (46%) was the most common abnormality on HRCT. Etiological profile was mainly found to be idiopathic pulmonary fibrosis in 19 (45%). Clinicoradiological correlation was seen in 35 cases, clinicohistological in 23 cases, and historadiological in 28 cases. Overall correlation between all the three modalities was established in 20 (46%) cases.

Conclusion:
The clinical suspicion of ILD is very important due to the varied etiologies and diseases with similar clinical presentations. Given the limitations of chest radiography, HRCT chest is the best noninvasive modality, while bronchoscopy is the most useful minimally invasive investigation tool to establish a diagnosis. Hence, multidisciplinary correlation is the best approach to evaluate a case of interstitial lung disease.

Authors: Ghoshdastidar Aloke , Roy Rajdeep , Paul Souvik , Mondal Lopamudra 
Published: December 2022

Background:
Worldwide pandemic due to the novel coronavirus, SARS COVID-19, forced the human race at a stake due to an unprecedented lockdown from March 23 to May 31, 2020. It jeopardized the normal quality of life to all population of India. Special sufferers were the infirmed people who need hospital-based management. Cancer patients were affected mostly as due to the fact that chemotherapy and radiotherapy are cycle specific and hospital specific as patients have to come to the hospital for getting radiation therapy.

Objective:
We aimed to assess how cancer patients were affected in a tertiary cancer care hospital.

Methodology:
During the lockdown period how much reduction of cancer service at different segments such as the outpatient department, indoor admission, teletherapy, and palliative care were influenced and were compared with the corresponding figures of the nonlockdown period of the previous 3 years were compared.

Results and Conclusion:
Around 30% reduction of hospital attendants in cancer follow-up clinics and new patient registration was attributed. More than 30% of patients failed to get radiotherapy compared to the previous years’ record. All these figures contributed adversely to upstage presentation in the postlockdown phase with obvious morbidity and mortality.
Aldehyde dehydrogenase 1 and CD44 serve as prognostic markers in patients with breast cancer
Authors: Pradhan Ayan , Sarkar Diptendra Kumar 
Published: December 2022

Background and Objective:
Breast cancer is the second leading cause of cancer-related death in women globally, and its prevalence is rising quickly, particularly in low- and middle-income nations. Despite significant advancements in treatment options, a small percentage of individuals with advanced-stage breast cancer have a dismal prognosis. The most extensively utilised markers for identifying breast cancer stem cells are ALDH1 and CD44 (BCSCs).
The goal of this study was to look into the expression of ALDH1 and CD44 in breast carcinoma and see if there was any correlation with other clinicopathological factors to see if they might be used to predict prognosis in patients with breast cancer.

Methods:
This study comprised 30 women with breast cancer who were undergoing mastectomy. Immunohistochemistry (IHC) labelling with an ALDH1, CD44 primary antibody was used to assess ALDH1, CD44 levels in paraffin-embedded tissues. The percentage of positive cells was used to assess the expression level, which was then associated with clinicopathological characteristics.

Results:
Out of 30 patients, 23 (76%) had CD44 positive; out of 30 patients, 21 had CD44 positivity (70 percent). ALDH1 expression was linked to the number of lymph nodes, while CD44 expression was linked to tumour size.

Conclusions:
In breast cancer, ALDH1 and CD44 expression acts as an independent prognostic indicators. However, bigger population-based prospective patient trials are needed to confirm these findings.

Published: December 2022

Objective:
The study aimed to determine the faculty of the health sciences students' knowledge and attitudes regarding the coronavirus disease 2019 (COVID-19) pandemic.

Materials and Methods:
This cross-sectional survey was completed with 317 undergraduate students of one health sciences faculty in Turkey. The data were collected between March 1, 2020, and March 15, 2020, by face-to-face interviews using a questionnaire created by the researchers. Number, percentage, mean, standard deviation, and Pearson Chi-square test were used to evaluate the data.

Results:
In this study, a high proportion of students answered questions about COVID-19 correctly. About 55.8% of the students took partial precautions against COVID-19 to protect themselves against COVID-19 and “frequent washing of hands” was the most common precaution. We determined that the main reasons for not taking any precautions against COVID-19 were “low number of cases in Turkey” and “getting irritated by the mask.” About 98.4% of the participants were entirely/partially following the news on COVID-19, with social media being the most commonly used medium. Female students took more protective measures than male students. The 1st-year students had more positive thoughts about vaccination compared to those in the other classes.

Conclusions:
Although the knowledge of the students about COVID-19 was good in the first wave of the pandemic, more than half of the students stated that they partially complied with the protective measures.

ABSTRACT.
Tuberculosis (TB) is an infectious disease that affects different organs, causing multiple complications, including hematological sequelae. One of the most common TB-hematological complications is anemia of chronic disease. Very rarely autoimmune hemolytic anemia (AIHA) has been reported as an uncommon manifestation of TB. In this case, we present a female who presented with refractory AIHA, which was attributed to disseminated TB. The patient responded well to steroids, anti-TB medications, and rituximab.
Effect of Herding Behaviour on Stock Price Movements at Nairobi Securities Exchange
Authors: Ngumi Patrick , Kazungu Khatibu , Mutasa Felician 
Published: December 2022

Purpose: Empirical evidence shows that herding pattern is experienced at NSE which is linked to particular periods.
Methodology: We observe the kind of herding characterised by changes in the stock market parameters which includes number of deals, average price, total purchases among other market parameters are as a result of unique circumstances as opposed to the overall market.
Findings: Further, results of both CSSD and CSAD indicated that herding has an effect on prices of shares and stocks. Idiosyncratic herding phenomenon detected can either be reduced or eliminated from portfolios through different diversifications strategies which are meant to reduce the levels of exposure to risk by merging various investment like bonds, real estates, stocks among others which are all not likely to be moving towards the same direction. Further, by encouraging diversification, also herding behaviour would be decreased by the simple fact that assets cannot move in the same direction at the same time and rate.
Unique Contribution to Theory, Practice and Policy: It is also recommended that the government should try to privatize some of its enterprises to enhance public participation in an effort to stabilise stock prices. This should be accompanied by alliances with exchange securities. The policy makers need further to consider forecasting the financial instability and thus regulate herding patterns in advance.

Authors: Peter Catherine Mueni , Mwenjeri Gabriel , Ngugi  Kahiu 
Published: December 2022

Purpose: The study seeks to determine the level of awareness and the highest amount consumers were willing to pay by positioning the novel product ready-to eat-cereals for breakfast Sorghum-pigeon pea processed from locally grown crop.
Methodology: Contingent Valuation Method (CVM) to assess consumer willingness to pay (WTP) for sorghum-pigeon pea flakes, which are Ready-to-Eat Cereals (RTEC). Three-stage sampling technique was used in selection of the two counties, and from each county three market places was identified. Glen sample size formula was used to obtain the total number of respondents, whereby a well semi-structured dichotomous questionnaire was used on 223 consumers from Makueni and Busia counties in Kenya. Double bounded logit model was employed in determining consumers' willingness to pay (WTP) for SPPF.
Findings: Results from the WTP assessment showed that consumers in both counties were willing to pay for the Sorghum-Pigeon Pea Flakes. The average WTP value in Busia and Makueni Counties was 140 and 136 Kenya Shillings, respectively. Further, nearly half of the respondents in both counties were aware of the ready-to-eat breakfast cereal SPPF for nutritional improvement. According to the findings of the double-bounded logit regression, being male, marital status, awareness of SPPF, and living in Busia County all positively influenced WTP for SPP. Having formal employment and household expenditure, on the other hand, had a negative impact on the WTP for SPPF.
Recommendations: The study recommends nutritional training to raise awareness of the benefits of consuming SPP. Furthermore, policies should focus on raising awareness of the nutritional benefits of SPPF among families, particularly those in Makueni.

Purpose: The study was carried out to determine the extent to which locus of control predict academic achievement in foundation of nursing among student nurses in Cross River State.
Methodology: Two research hypothesis were formulated and tested at .05 level of significance. The study adopted the Ex-post facto research design. To test the hypothesis, a questionnaire titled 'Locus of control and academic achievement was used. The questionnaire contained two sections; section A and section B. Section A contained 12 items with a Cronbach reliability estimate of .85. Section B contained 50 multiple choice questions with a Kuder-Richardson (k-R20) reliability estimate of .92. The questionnaires were administered on 766 student nurses from 100 to 300 level of study from all the four schools of nursing in Cross River State. The data collected were analyzed using simple linear regression and multiple linear regression.
Findings: The research finding showed that internal locus of control does not significantly predict academic achievement in Foundation of Nursing among student nurses. While external locus of control significantly predicts academic achievement in Foundation of nursing among student nurses.
Recommendations: Based on these findings, the researcher recommends that there should be attribution training for learners at all levels of education to encourage attribution to controllable factors. Also, parents, teachers, educational psychologist, counsellors and significant other should encourage students to see themselves as originals and not as pawns.
