Tantrums are strong emotional outbursts that occur when a child feels out of control. Tantrums are not harmful behavior, but if not controlled, this behavior will affect the child's life in the future. One way to control tantrums is to apply behavior modification, one of which is operant extinction. The design used in this study is a design with a repetition (reversal) with an A-B-A pattern. The application of this technique is carried out on children aged 12 years who often have tantrums if their desires are not fulfilled, especially regarding the habit of being fed while eating. Based on the intervention carried out for 14 times, the subject's tantrum behavior decreased, although not significantly. Good cooperation is needed, especially from the closest environment (mother's family) to reduce the subject's tantrum behavior. Keywords: Tantrum, child, operant extinction

ABSTRACT
At present climate changes and extreme weather events which are significantly affects the productivity of coconut in the major coconut growing areas in the country and ultimately it will threaten the livelihood of coconut cultivating community. The present study was undertaken to determine the coconut growers’ knowledge and perceptions about climate change and adaptation strategies. The study was conducted in Puttalam district which is more vulnerable to climate change impacts. The study sample comprised of 140 coconut growers. The study findings emphasized that notable fraction of growers have fairly high knowledge and perceptions about climate change and various impacts. Further, age, education and farming experience were found to be positively related and gender, land holding, family size, land ownership were negatively related with growers’ knowledge and perceptions. Additionally, age, family size and education were found to be significantly related with growers’ knowledge and only the family size and education were found to be significantly related with growers’ perceptions. Moreover, growers’ knowledge was positively and significantly related with their perceptions and adaptation measures as well as perceptions also positively and significantly related with adaptation measures. Also, findings showed that significant importance to create extension and awareness campaigns to educate the coconut growers about climate change related risks and uncertainties and suitable adaptation strategies. Therefore, agriculture policy makers should more focus on mitigating impacts of climate change to enhance the sustainable coconut cultivation in the country with providing more information, financial supports and subsidies to growers to adopt suitable adaptation measures.

Abstract
Modern galaxy simulations have reached the complexity required to create sophisticated mock catalogs. Ananke is a set of nine mock catalogs constructed from synthetic surveys of three Milky Way-like galaxies from the Latte suite of FIRE simulations. Ananke provides observed quantities for comparison with modern large-scale stellar surveys. In SDSS-IV DR17, mock catalogs for the Apache Point Galactic Evolution Experiment (APOGEE) were built from Ananke synthetic surveys as a Value-Added Catalog, but were only provided as large flat files (∼>10's GB). Here we announce an >40 Tb SQL database for nine APOGEE-specific mock catalogs and describe additions to the data model necessary for effective user queries. The catalogs can be accessed on the free, science platform, SciServer—supported by the Institute for Data Intensive Engineering and Science at the Johns Hopkins University (IDIES); SciServer supports server-side analysis with commonly used coding languages and tools.

Objective The literature describing follow-up carotid contrast-enhanced ultrasonography (CEUS) is limited. We report our experience with monitoring CEUS that is performed in patients with Takayasu arteritis (TAK). Methods We retrospectively analyzed patients with TAK who had undergone carotid CEUS 2 or more times with a follow-up duration of 12 or more months at Xijing Hospital between 2017 and 2020. We described how CEUS interpretation changed, and we recorded the state of remission (ie, bilateral CEUS visual grades ≤ 1) or relapse as determined by imaging. Results In total, 106 patients with TAK and 425 CEUS visits were included in the study; the median follow- up was 25 (IQR 18-30) months. The CEUS vascularization grade was significantly associated with the Kerr criteria (r = 0.532, P < 0.001), erythrocyte sedimentation rate (P < 0.001), and C-reactive protein level (P < 0.001). At baseline, 76 patients (71.7%) had active disease as determined by CEUS and 30 (28.3%) had inactive disease. The midterm assessment (median 13, IQR 10-16 months) showed that 29 out of 76 CEUS-active patients (38.2%) achieved complete response, 34 (44.7%) achieved partial response, and 13 (17.1%) did not respond. At the last visit, the total number of responders was 78 out of 94 (83.0%). CEUS relapse was observed in 28 out of 57 (49.1%) patients, with a median of 16 (IQR 10-21) months. The Kaplan-Meier curve demonstrated that the remission rate evaluated by the CEUS-combined method (median 22 months) was lower than that of the clinical-only evaluation (median 11 months; P < 0.001). Conclusion Response or relapse according to CEUS was detected in most patients during follow-up. CEUS is an effective technique for detecting carotid artery inflammation in patients with TAK.

ObjectiveTo evaluate the impact of a wearable activity tracker used to encourage physical activity, on disease flares in patients with spondyloarthritis (SpA).MethodsThis randomized controlled trial involved randomizing 108 patients with SpA into tracker and nontracker groups. The participants were then subjected to assessments of disease activity, performance (6-minute walk test), and quality of life (QOL; 36-item Short Form Health Survey) at the 12th, 24th, and 36th week. The primary outcome was the change in the frequency of flare episodes (categorized as no flare, flare in ≤ 3 days, and flare in > 3 days) between baseline and 12 weeks.ResultsThe results of the study showed that at the 12th week, the mean change (∆) of the number of flares improved in both groups: −0.32 (95% CI −0.66 to 0.02) and −0.38 (95% CI −0.68 to −0.09) in the tracker and nontracker group, respectively. However, the between-group differences were insignificant (P= 0.87). Performance scores improved in both groups at the 12th, 24th, and 36th week (allP< 0.01). The different dimensions of QOL also improved at the 12th week (P< 0.01). Conversely, moderate flares (P< 0.01) and performance (P< 0.01) improved over time; however, the influence over time of a wearable activity tracker was not significant (P= 0.29 andP= 0.66, respectively).ConclusionThe use of a wearable activity tracker did not affect the number of flares, performance, or QOL of patients with SpA. Nevertheless, this study confirmed the benefits of physical activity on flares, disease activity, QOL, and physical performance in patients with SpA.

Published: June 2022

ObjectiveMelanoma differentiation-associated gene 5 (MDA5) is a viral RNA sensor induced by SARS-CoV-2. Similarities have been reported between the clinical presentations of coronavirus disease 2019 (COVID-19) pneumonia and anti-MDA5 antibody–positive interstitial lung disease (anti-MDA5-ILD). However, it is unknown whether COVID-19 mRNA vaccines are associated with anti-MDA5-ILD.MethodsWe retrospectively reviewed consecutive patients with anti-MDA5-ILD admitted to our hospital between April 2017 and March 2022. In addition, we investigated the clinical presentations of patients who developed anti-MDA5-ILD after vaccination with COVID-19 mRNA vaccines. We also examined the annual number of anti-MDA5-ILD cases before and after the COVID-19 vaccination campaign.ResultsNine patients with anti-MDA5-ILD were seen during the study period, of whom 4 developed anti-MDA5-ILD between August and October 2021, approximately 6 to 12 weeks after vaccination with a COVID-19 mRNA vaccine and a few months after the rapid mRNA COVID-19 vaccination campaign in Japan. None of the 4 patients had evidence of SARS-CoV-2 infection. The difference in the annual number of anti-MDA5-ILD cases before vs after the COVID-19 vaccination campaign (1.25 ± 0.96 cases/yr vs 4.0 cases/yr) was not statistically significant (P= 0.08).ConclusionWe encountered 4 cases of anti-MDA5-ILD after COVID-19 vaccination. Further large population studies are needed to clarify the relationship between anti-MDA5-ILD and vaccination with COVID-19 mRNA vaccines.
