Alat komunikasi antara anggota masyarakat berupa lambang bunyi ujaran yang dihasilkan oleh alat ucap manusia disebut bahasa. Bahasa harus dipelajari, tidak ada seorang manusia di kehidupan dunia ini yang baru lahir langsung bisa berbahasa tertentu. Untuk mempelajari suatu bahasa mesti melalui proses yang relatif terus-menerus dijalani dari berbagai pengalaman. Pengalaman inilah yang membuahkan hasil yang disebut belajar. Belajar bahasa tentu memerlukan strategi atau rencana yang cermat agar dapat mencapai tujuan pembelajaran yang baik. Biasanya yang berkaitan dengan belajar bahasa adalah guru dan peserta didik, dalam hal ini peserta didik tingkat sekolah menengah pertama (SMP). Salah satu unsur dalam strategi pembelajaran bahasa adalah menguasai teknik-teknik penyajian atau metode mengajar. Pembelajaran akan berlangsung dengan efektif dan efisien apabila didukung dengan kemahiran guru mengatur strategi pembelajaran. Cara guru mengatur strategi pembelajaran sangat berpengaruh terhadap cara peserta didik dalam belajar

Limbah perkebunan merupakan salah satu masalah yang belum sepenuhnya terselesaikan dengan baik. Umumnya limbah perkebunan hanya dimanfaatkan sebagai kompos. Penelitian ini bertujuan untuk mengetahui stabilitas zat warna yang terkandung dalam limbah ekstrak kulit buah kakao (Theobroma cacao, L) yang terlihat dari nilai absorban sampel terhadap variasi lingkungan yakni suhu penyumpanan dan derajat keasaman (pH) sehingga limbah perkebunan dapat dijadikan alternatif sebagai bahan pewarna makanan alami. Uji spektofotometrik dilakukan untuk melihat nilai absorban zat warna pada ekstrak sampel. Sampel limbah kulit buah kakao (Theobroma cacao, L) diperoleh dari perkebuanan rakyat di Desa Persiapan Pansor Kecamatan. Hasil penelitian menunjukan bahwa ekstrak kulit buah kakao (Theobroma cacao, L) lebih stabil pada penyimpanan dalam suhu ruangan (24oC) dan pada pH 5. Sampel basah lebih stabil terhadap suhu ruangan dibandingkan dengan sampel kering, namun lebih rendah kandungan pigmen warnanya pada berbagai variasi derajat keasaman (pH) dibandingkan dengan sampel kering.
Microdosimetry and Dose-Averaged LET Calculations of Protons in Liquid Water: A Novel Geant4-DNA Application

Published: October 2021

The spatial distribution of energy deposition events is an essential aspect in the determination of the radiobiological effects of ionizing radiation at the cellular level. Microdosimetry provides a theoretical framework for the description of these events, and has been used in several studies to address problems such as the characterization of Linear Energy Transfer (LET) and Relative Biological Effectiveness (RBE) of ion beams for proton therapy applications. Microdosimetry quantities and their distributions can be obtained by means of Monte Carlo simulations. In this work, we present a track structure Monte Carlo (MC) application, based on Geant4-DNA, for the computation of microdosimetric distributions of protons in liquid water. This application provides two sampling methods uniform and weighted, for the scoring of the quantities of interest in spherical sites, with diameters ranging from 1 to 10 μm. As an element of novelty, the work shows the approach followed to calculate, without resorting to dedicated simulations, the distribution of energy imparted to the site per electronic collision of the proton, which can be used to obtain the macroscopic dose-averaged LET as proposed by Kellerer. Furthermore, in this work the concept of effective mean chord length is proposed to take into account δ-ray influx and escape in the calculation of macroscopic dose-averaged LET for proton track segments and retrieve the agreement predicted by Kellerer’s formula. Finally, the results obtained demonstrate that our MC application is reliable and computational-efficient to perform calculations of microdosimetric distributions and dose-averaged LET of proton track segments in liquid water.

Published: October 2021

Background: Postpartum depression (PPD) is commonly seen in women after birth and can lead to adverse effects on both the health of mothers and child(ren) development. In Vietnam, there have been a number of studies examining the rate and risk factors of PPD, but none has provided a systematic review.Aim: This current literature review aims to summarize and synthesize the current state of knowledge of studies conducted in Vietnam to provide a comprehensive understanding of the PPD phenomena during the last 10 years.Data Sources: A literature search was conducted relying on the most common online databases—MEDLINE/PubMed, ScienceDirect, and Google Scholar, which included articles if they (i) examined prevalence or risk factors of PPD; (ii) were conducted among Vietnamese participants using either quantitative, qualitative, or mixed-method, and (iii) were published from 2010 to 2020. After the filtering process, 18 articles were eligible to be reviewed.Results: Research studies in Vietnam on PPD are conducted among women at and after 1-month delivery. The rate of PPD reported in Vietnam among mothers at postnatal time points from 1 to 12 months ranged from 8.2 to 48.1%. Risk factors can be clustered into three groups: personal factors, family factors, and environmental factors.Recommendation: Further research studies should focus on examining PPD at an earlier stage within the first month after birth. The investigation of risk factors in a comprehensive manner for Vietnamese mothers would also be recommended.

Published: October 2021

Background: Little research has tested associations of pain and MC use after long-term treatment and through methods that have external validity outside experimental settings. The study examined associations of pain, associated painful experiences, and long-term medical cannabis (MC) use in chronic pain (CP) patients using a naturalistic daily diary study that provided novel and externally valid data.Methods: Data were obtained from 78 MC users with CP three times daily over a 10-day period (nobservations = 1,688). Mixed-effects models were used to test the associations between MC use and momentary experiences of pain, affect, and fatigue.Results: Within persons, elevated experiences of pain intensity were associated with greater intention to use MC within the next hour. No evidence was found that the time lapse since last MC use was associated with pain levels, negative affect, or fatigue.Conclusions: The results imply that after long-term use, CP patients intend to use MC in response to pain experiences. Yet, they may not actually achieve the pain relief. More research is needed to examine whether continued MC use despite lack of pain relief is related to relief of other symptoms (e.g., dependence, withdrawal) or positive benefits (e.g., general sense of well-being) or tolerance.

Objective: The aim of this study was to investigate the prevalence of workplace violence against health care workers, to explore the combined association of work stress, psychological job demands, and social approval with workplace violence and their respective mechanisms among health care workers.Methods: Using data from the Chinese Sixth National Health Service Survey (NHSS) in 2018 conducted among 1,371 health care workers in Sichuan province of China. A self-administered structured questionnaire was used to collect data on health care workers' socio-demographic and work-related characteristics, work stress, psychological job demands, social approval, and workplace violence. We used structural equation modeling (SEM) to test the hypothesized relationship among the variables.Results: The results showed that a total of 77.0% health care workers were exposed to workplace violence. Work stress was directly related to workplace violence (β = 2.167, 95%CI: 1.707, 2.627), while psychological job demands and social approval had indirect associations with workplace violence via work stress [β = 0.427, 95%CI: 0.297, 0.557; β = −0.787, 95%CI: (−0.941)–(−0.633)]. Both psychological job demands (β = 0.197, 95%CI: 0.139, 0.255) and social approval [β = −0.346, 95%CI: (−0.399)–(−0.294)] had direct associations with work stress, while social approval had direct association with psychological job demands [β = −0.085, 95%CI: (−0.136)–(−0.034)]. Psychological job demands mediated the relationship between social approval and work stress.Conclusion: Overall, decreasing workplace violence among health care workers requires to promote interventions to reduce work stress and psychological job demands by improving social approval.

Published: October 2021

Background: Anterior cervical discectomy and fusion (ACDF) has been widely performed to treat cervical generative diseases. Cage subsidence is a complication after ACDF. Although it is known that segmental kyphosis, acceleration of adjacent segmental disease, and restenosis may occur due to cages subsidence; however detailed research comparing zero-profile cages (ROI-C) and conventional plate and cage construct (CPC) on cage subsidence has been lacking.Objective: The objectives of this study was to compare the rate of postoperative cage subsidence between zero profile anchored spacer (ROI-C) and conventional cage and plate construct (CPC) and investigate the risk factors associated with cage subsidence following ACDF.Methods: Seventy-four patients with ACDF who received either ROI-C or CPC treatment from October 2013 to August 2018 were included in this retrospective cohort study. Clinical and radiological outcomes and the incidence of cage subsidence at final follow up-were compared between groups. All patients were further categorized into the cage subsidence (CS) and non-cage subsidence (NCS) groups for subgroup analysis.Results: The overall subsidence rate was higher in the ROI-C group than in the CPC group (66.67 vs. 38.46%, P = 0.006). The incidence of cage subsidence was significantly different between groups for multiple-segment surgeries (75 vs. 34.6%, P = 0.003), but not for single-segment surgeries (54.55 vs. 42.30%, P = 0.563). Male sex, operation in multiple segments, using an ROI-C, and over-distraction increased the risk of subsidence. Clinical outcomes and fusion rates were not affected by cage subsidence.Conclusion: ROI-C use resulted in a higher subsidence rate than CPC use in multi-segment ACDF procedures. The male sex, the use of ROI-C, operation in multiple segments, and over-distraction were the most significant factors associated with an increase in the risk of cage subsidence.

Case management – rapid diagnosis and prompt administration of artemisinin-based combination therapy (ACT) – is a fundamental pillar of recommended malaria interventions in Somalia. Unfortunately, the emergence and spread of drug resistant falciparum parasites continues to pose a considerable threat to effective case management.
With technical and financial support from WHO, the efficacy of recommended ACTs has been regularly monitored in sentinel sites since 2003. These studies provided evidence that supported the adoption of artesunate-sulfadoxine/pyrimethamine as first-line treatment in 2005 and artemether-lumefantrine as second-line treatment in 2011. Efficacy studies conducted between 2011 and 2015 showed high artesunate-sulfadoxine/pyrimethamine treatment failure rates of 12.3% - 22.2%, above the threshold (10%) for a change of treatment policy as recommended by WHO. This was also associated with high prevalence of quadruple and quintuple mutations in the dihydrofolate reductase (Pfdhfr) and dihydropteroate synthase (Pfdhps) genes, which are associated with sulfadoxine/pyrimethamine resistance.
Based on these findings, national malaria treatment guidelines were updated in 2016, with artesunate-sulfadoxine/pyrimethamine replaced by artemether-lumefantrine as first-line treatment and dihydroartemisinin-piperaquine recommended as second-line treatment. Subsequent efficacy studies in 2016 and 2017 confirmed that both the current first- and second-line treatments remain highly efficacious (cure rate above 97%). Technical and financial support from WHO has been instrumental in generating evidence that informs malaria treatment policy and should therefore continue to ensure that effective treatments are available to malaria patients in the country.

Published: October 2021

Remote English teaching becomes a trend during the pandemic of Covid-19 outbreak. Schools in Indonesia are forced to conduct teaching and learning activity remotely during Work from Home (WFH) regulation. However, not all teachers were ready to teach virtually. This study aimed at investigating the teachers’ and students’ readiness toward remote English teaching. The subject were the English teachers at SMAN 1 Kubutambahan. An explanatory sequential mixed-method design was implemented in this research. The data were collected through an online survey and followed up with an interview. The data were collected through an online survey and analysed using Ideal Mean score analysis. The survey used a questionnaire which contain four dimensions, namely technology, innovation, people, and self-development to investigate the teachers’ and students’ readiness level. The research finding showed that English teachers were categorized in the ready category, which means they were ready in conducting remote English teaching. The result of this research can be used as an evaluation for the teacher in order to improve their readiness level in the future.

Authors: Grover Sandeep , Davuluri Triveni , Chakrabarti Subho 
Published: October 2021

Background:Religion plays an important role in the life of a large proportion of population. Various dimensions of religion and religiosity have not been thoroughly investigated in persons with schizophrenia. Aim: This study aimed to develop a simple instrument to assess various aspects of religiosity, which can influence the assessment and management of schizophrenia and evaluate the same in a group of patients, who are currently in clinical remission.Methodology:A simple semi-structured interview was developed to assess various dimensions of religion relevant to patients with mental illnesses. The questionnaire was administered to 100 patients with schizophrenia.Results:About two-thirds of the patients gave religious and supernatural explanations for their delusions, hallucinations, and other symptoms. More than three-fourth (78%) of patients reported that their religious beliefs influence their intake of the prescribed medications. The majority of the patients believed that God was helping them in dealing with their illness to some extent (29%) or very much (57%). About four-fifth (81%) of the patients attributed their illness to one religious or supernatural etiological cause. About two-fifths (39%) of the patients were first taken to a magico-religious faith healer at the onset of symptoms. In terms of treatment practices along with treatment from the tertiary care center, during the most recent relapse, the majority (82%) of the patients took recourse to at least one of the religious or supernatural modalities.Conclusion:The designed instrument provides a broad coverage of various aspects of religious practices which are prevalent in patients with schizophrenia. The use of this instrument in patients with schizophrenia suggests that religious beliefs and practices influence the type of psychopathology, etiological models about the illness, help seeking, and medication adherence.
