Published: November 2021

Soap is a type of cleaning product that is used to clean dust, oil, dirt, germs, and bacteria that stick to the skin. Ginger is a plant that contains a wide range of antibacterial compounds including E. Coli, Staphylococcus aureus, B. Cereus, L monocytogenes and Candida albicans bacteria. Soap is made by chemically reacting sodium or potassium compounds with fatty acids derived from vegetable oil or animal oil. This study aims to determine the physical characteristics of solid soap with ginger rhizome extract with a combination of coconut oil and palm oil and analyze the panelist’s response to the soap produced. In the third week of observation, it is known that the water content ranges from 0,07%-0,1% with foam stability 71,11%-88,23% and pH 8,96-9,08. The most preferred solid soap based on the response of the panelist is soap from a mixture of coconut oil and palm oil with a ratio of 15:5.

Introduction: A dental medical record is a systematic documentation of a patient, provided by the dentists. Various information including the patient data, diagnoses, treatments, and odontogram are recorded in the dental medical records. In Indonesia, the guideline of dental medical records has been established by the Ministry of Health. However, the preliminary study by the Department of Forensic Odontology, Faculty of Dental Medicine Universitas Airlangga, showed that many dentists documented the medical records, not following the Medical Record Guidelines from the Ministry of Health. Purpose: This study aims to determine the dentists’ understandings of the completeness of dental medical records according to the Dental Medical Record Guidelines by the Ministry of Health of Indonesia. Methods: A total of 358 dentists in East Java participated in this study by fulfilling an online questionnaire. Results: The results showed that approximately 27.4% of the respondents are conducting dental medical records following Dental Medical Record Guidelines. Conclusion: The results of this study are expected to be considered as a reference for the implementation of socialization on the Dental Medical Record Guidelines and the formulation of policies that regulate the use of dental medical records following national standards.
DETERMINANTS OF NEONATAL MORTALITY BASED ON THE 2017 INDONESIAN DEMOGRAPHIC AND HEALTH SURVEY (IDHS)
Authors: Rumiati Fidya , Adisasmita Asri C.
Published: November 2021

ABSTRACTInfant mortality is still a major health problem in Indonesia as 63% of deaths occur in the neonatal period. The trend of the neonatal mortality rate in Indonesia has decreased from 15 (2017) to 13 deaths per 1,000 live births (2018), but this does not meet the Sustainable Development Goals (SDGs) target. Evidence-based health interventions are based on determinants that most influences neonatal mortality. The purpose of this study was to determine the most influential determinants of neonatal mortality in Indonesia. This research is an analytic observational study that uses the 2017 Indonesian Demographic and Health Survey (IDHS) data, with a cross-sectional design. This study’s population was the last baby of married women of childbearing age (15-49 years) and was recorded in the 2017 IDHS with a sample of 15,102 babies. The outcome variable in this study was neonatal mortality. The analysis was conducted in stages, namely univariate analysis, bivariate analysis using the chi-square statistical test (X2), and multivariate analysis using logistic regression. The results showed that 85.71% of deaths occurred in the early neonatal period. The most influential determinants of neonatal mortality were male sex (adj OR = 2.91: 95% CI 1.78-4.76), low birth weight (adj OR = 12.08: 95% CI 7.38-18.86) and parity status ≥ 4 (adj OR = 2.11: 95% CI 1.22-3.61). Public health interventions aimed at reducing neonatal mortality should be linked to newborn and maternal characteristics that significantly influence Indonesia's neonatal mortality. Therefore, health services must consider adequate postpartum neonatal care that is fully integrated with medical care. Moreover, further prevention of potential factors that cause low birth weight before conception should be implemented and further control of births would optimize the family planning program. Keywords: gender, low birth weight, parity status, determinant, neonatal mortality, Indonesia

HEALTH BELIEF APPLICATION MODEL: KNOWLEDGE AND PATTERNS OF IRON SOURCE FOOD CONSUMPTION AS A PREVENTIVE EFFORT FOR ANEMIA EVENTS
Authors: Andani Stefani Verona Indi , Mahmudiono Trias , Adhela Yurike Dhika
Published: November 2021

ABSTRACT Female adolescents are prone to iron deficiency anemia due to regular menstrual cycles and loss of basal, thus requiring sufficient iron intake from food consumed daily. The concept of the Health Belief Model which consists of perceived susceptibility, perceived severity, perceived benefit, perceived barrier, and self efficacy helps to take action on the prevention of anemia. This study aimed to analyze the correlation of knowledge, the Health Belief Model, and consumption patterns with anemic status at Saint Stanislaus High School. This study used a cross-sectional design. The population in this study were all female students in grade X and XI of Saint Stanislaus Senior High School, totaling 84 people. The cluster random sampling technique was used to calculate the total amount of samples, totaling 46 people as the sample of this study. The data collected included respondent characteristics, knowledge rate, construction of Health Belief Model, consumption patterns of iron source foods differentiated into levels of adequacy and frequency of eating, and anemia status. The results of this study showed that 14 of the respondents aged 16 years experienced anemia (30.43%). The correlation of knowledge and the incidence of anemia significantly correlated, with a p-value of 0.044 (p <0.005). Meanwhile, constructs of the Health Belief Model and the level of adequacy of food consumption of iron sources had no correlation with the incidence of anemia (p> 0.005). The frequency of kale consumption as a source of non heme iron had a correlation with the incidence of anemia (p <0.005). This study concluded that there was a correlation with knowledge and the incidence of anemia in Saint Stanislaus High School students. Proper nutrition education based on the concept of the Health Belief Model can be given to students to let them have an understanding, good attitude, and practice prevention measures for anemia well. Keywords: knowledge, Health Belief Model, iron consumption pattern, anemic

Depression and Autoimmune Thyroiditis - Their Relationship and the Effects of Treating Psychiatric and Thyroid Disorders on Changes in Clinical and Biochemical Parameters Including BDNF and Other Cytokines
Authors: Kotkowska Zofia , Strzelecki Dominik
Published: November 2021

Various autoimmune diseases, including autoimmune hypothyroidism (AHT), are associated with a higher risk of developing mood disorders throughout life. Depression is accompanied by the changes in the levels of inflammatory and trophic factors, including interleukines (IL-1beta, IL-2, IL-6), interferon alpha (IFN-alpha), tumor necrosis factor alpha (TNF-alpha), C-reactive protein (CRP) and brain derived neurotrophic factor (BDNF). Similar disturbances in the cytokine profile are seen in AHT patients and their relatives. Disclosure of the relationship between the co-existence of depression and autoimmune subclinical thyroiditis indicates that the pathomecha-nism of depression may be related to the changes in the immune system, it is possible that both conditions may be caused by the same immune processes. The above hypothesis is indirectly sup-ported by the observations that the treatment with both antidepressants and levothyroxine leads to a decrease in the levels of proinflammatory cytokines with an increase in BDNF concentrations, simultaneously correlating with an improvement in the clinical parameters. However, so far there are no long-term studies determining the causal relationship between depression, thyroid auto-antibodies, and cytokine profile, which could bring us closer to understanding the interrelation-ships between them and facilitate the use of an adequate pharmacotherapy, not necessarily psy-chiatric. We consider the above issues insufficiently investigated but of great importance. This ar-ticle is an overview of the available literature as well as an introduction to our research project.

Fat reduction and anti-inflammation are commonly claimed properties of probiotics. Lactobacillus plantarum and Enterococcus faecium were tested in high fat-induced obesity mice and in vitro experiments. After 16 weeks of probiotics, L. plantarum outperforms E. faecium on the anti-obesity property as indicated by body weight, regional fat accumulation, serum cholesterol, inflammatory cytokines (in blood and colon tissue), and gut barrier defect (FITC-dextran assay). With fecal microbiome analysis, L. plantarum but not E. faecium reduced fecal abundance of pathogenic Proteobacteria without an alteration in total Gram-negative bacteria when compared with non-probiotics obese mice. With palmitic acid induction, the condition media from both probiotics similarly attenuated supernatant IL-8, improved enterocyte integrity and down-regulated cholesterol absorption-associated genes in Caco-2 cell (an enterocyte cell line) and reduced supernatant cytokines (TNF-α and IL-6) with normalization of cell energy status (extracellular flux analysis) in bone-marrow-derived macrophages. Because the anti-inflammatory effect of the condition media of both probiotics on palmitic acid-activated enterocytes was neutralized by amylase, the active anti-inflammatory molecules might, partly, be exopolysaccharides. As L. plantarum out-performed E. faecium in anti-obesity property, possibly through the reduced fecal Proteobacteria, with a similar anti-inflammatory exopolysaccharide; L. plantarum is a potentially better option for anti-obesity than E. faecium.
PCR, PLS, or OPLS Evaluation of different regression techniques for hypothesis generation
Authors: Ahuja Avani
Published: November 2021

In the current era of ‘big data’, scientists are able to quickly amass enormous amount of data in a limited number of experiments. The investigators then try to hypothesize about the root cause based on the observed trends for the predictors and the response variable. This involves identifying the discriminatory predictors that are most responsible for explaining variation in the response variable. In the current work, we investigated three related multivariate techniques: Principal Component Regression (PCR), Partial Least Squares or Projections to Latent Structures (PLS), and Orthogonal Partial Least Squares (OPLS). To perform a comparative analysis, we used a publicly available dataset for Parkinson’ disease patien ts. We first performed the analysis using a cross-validated number of principal components for the aforementioned techniques. Our results demonstrated that PLS and OPLS were better suited than PCR for identifying the discriminatory predictors. Since the X data did not exhibit a strong correlation, we also performed Multiple Linear Regression (MLR) on the dataset. A comparison of the top five discriminatory predictors identified by the four techniques showed a substantial overlap between the results obtained by PLS, OPLS, and MLR, and the three techniques exhibited a significant divergence from the variables identified by PCR. A further investigation of the data revealed that PCR could be used to identify the discriminatory variables successfully if the number of principal components in the regression model were increased. In summary, we recommend using PLS or OPLS for hypothesis generation and systemizing the selection process for principal components when using PCR.rewordexplain later why MLR can be used on a dataset with no correlation

Towards the Next Stage of the Journal of Disaster Research
Authors: Board Journal of Disaster Research Editorial
Published: November 2021

In the year 2021, the Journal of Disaster Research (JDR) had two memorable events: Professor MURAKAMI Suminao, one of the founders of the Journal, resigned as the editor-in-chief, and in February the JDR marked its hundredth issue, counting from Vol.1 No.1. These events gave us, the next generation of the editorial board members, the resolve to reinvent the JDR for its leap forward into the next stage.

We have accomplished the following two projects this year.

Establishment of MURAKAMI Suminao Award for Disaster Research and the JDR annual awards

To acknowledge Professor MURAKAMI’s significant contributions to the JDR and disaster research in general, we rename the JDR Award to the MURAKAMI Suminao Award for Disaster Research. While we present this award to the person who has made the most significant contribution to disaster research as a whole, we hereby establish three more specific JDR annual awards: the JDR Award for the Most Cited Paper, the JDR Award for the Most Downloaded Article, and the JDR Award for the Most Contributory Reviewer.

Applying the Creative Commons license

The JDR introduced the Creative Commons license in August 2021, thereby becoming a fully open-access journal conforming to the international standard. This project makes all articles in the JDR easier to reuse and cite in academic activities.

Now the JDR is widely known not only in Japan but also all across Asia, and its readership is spreading through North America and Europe. We will continue to strive for the further development of the JDR as an international journal dedicated to comprehensive disaster research.

Published: November 2021

Dampak dari tidak optimalnya manajemen sampah pada Kelurahan Jakamulya yang selalu terkena banjir akibat sampah dan Situ Wo yang tidak bisa menampung air. Upaya-upaya untuk mengelola sampah dari sumbernya sudah dilakukan dengan bank sampah namun belum optimal. Tujuan Program Kemitraan Wilayah Kota Bekasi adalah peningkatan partisipasi masyarakat dalam pengelolaan Sampah dengan konsep 3R (reuse, recycle, reduce).  

Berdasarkan hasil penerapan program PKW dapat disimpulkan bahwa operasional  Bank sampah Mutiara Pondok Suryamandala di Kelurahan Jakamulya Kota Bekasi berbasis TPS 3R menjadi kunci penanganan sampah berbasis masyarakat (komunal) sangat efektif untuk pengelolaan sampah yang langsung masyarakat sebagai pengelola plus (pemilik home industri). Tanpa system komunal ini mustahil sampah dapat diatasi dengan tuntas atau berkelanjutan. Membudayakan cara pembuangan sampah yang baik mulai dari lingkungan rumah tangga hingga dengan cara menyerahkan sampah ke Bank Sampah adalah metoda efektif di tingkat masyarakat yang akhirnya akan memandirikan masyarakat dalam mengelola sampahnya sendiri. Menata TPS 3R menjadi pusat pemanfaatan sampah organik dan anorganik secara maksimal merupakan program pengelolaan sampah berbasis komunal yang secara pasti akan memotong mata rantai distribusi sampah dari TPS 3R ke tempat pembuangan akhir.

Intensive culture of Cylindrotheca closterium (Ehrenberg) Reimann et Lewin on the nutrient medium with sodium bicarbonate
Authors: Zheleznova S. N. , Gevorgiz R. G.
Published: November 2021

The possibility is shown experimentally of using sodium bicarbonate in a nutrient medium to provide C. closterium culture with carbon under conditions of intensive cultivation without supplying CO2 to the suspension. After C. closterium adaptation to a nutrient medium with sodium bicarbonate with a concentration of 1.2 g·L−1, active growth is observed, with a maximum productivity of 0.6–0.7 g·(L·day)−1 of dry weight. Carbon penetrates into diatom cells both in the form of carbon dioxide and bicarbonate ions. However, all nutrient media for artificial cultivation of diatoms still require using CO2 from the atmosphere or from a gas cylinder. The aim of this work is to assess the possibility of using sodium bicarbonate to provide C. closterium with carbon under conditions of intensive cultivation without supplying CO2 to the suspension. The culture was grown in the mode of accumulative cultivation in a 1-L flask on the RS nutrient medium prepared with sterile Black Sea water; its composition was as follows (g·L−1): NaNO3 – 0.775; NaH2PO4·2H2O – 0.0641; Na2SiO3·9H2O – 0.386; Na2EDTA – 0.0872; FeSO4·7H2O – 0.045; CuSO4·5H2O – 0.2·10−3; ZnSO4·7H2O – 0.44·10−3; CoCl2·6H2O – 0.2·10−3; MnCl2·4H2O – 0.36·10−3; and NaMoO4·H2O – 0.12·10−3. Previously, 1.2 g·L−1 of sodium bicarbonate was dissolved there. Сell suspension was stirred with a magnetic stirrer (250 rpm). On the 4th day of the experiment, 1 g of NaHCO3 and 2 mL of 0.1 N hydrochloric acid were added to the culture in order to lower the medium pH down to 8.6. From the 2nd day of the experiment, active growth was observed, with a maximum productivity of 0.6 g·(L·day)−1. After adding 1 g·L−1 of sodium bicarbonate to the actively growing culture and lowering pH down to 8.6, the growth rate approached almost zero, but considering the increase rate of the medium pH during adaptation, the culture actively absorbed bicarbonate ions. The possibility of cultivating the benthic diatom C. closterium on a nutrient medium with a high sodium bicarbonate content is experimentally shown. As found, on the RS nutrient medium with 1.2 g·L−1 of sodium bicarbonate added under conditions of intensive cultivation, C. closterium maximum productivity reaches 0.7 g·(L·day)−1, with a significant increase in the medium pH. According to our data, optimal medium pH for C. closterium growth is in the range of 8.4–9.4. At higher values (pH > 9.4), the growth of diatoms slows down; at pH = 9.9, the culture enters the dying phase.

Assessment of the interaction of marine farms with the environment in the industrial cultivation of the mussel Mytilus galloprovincialis is very important. In the mussel farm – environment system, biotic fluxes of chemical compounds through gonads, gametes (sperm and eggs), and larvae make a considerable contribution to this interaction. Since gonads play a key role in the mussel reproduction, it is interesting to study the budget of materials, that are directly involved in this process. Out of these materials, testosterone, estradiol, fatty acids, and some trace minerals, such as Se and Zn, are known to affect spawning, growth, and development. The molluscs absorb these materials from food and water. These materials are partly metabolically assimilated by mussels and partly excreted into the environment with gametes. The aim of this study was to estimate the components of the budget of steroid hormones, fatty acids, and two essential trace elements (Zn and Se) in mussel gonads, gametes, and larvae. The total testosterone and estradiol in gonads and gametes were quantified by enzyme-linked immunosorbent assay. The contents of the trace elements were found using inductively coupled plasma mass spectrometry. The fatty acid composition was determined by means of gas chromatography–mass spectrometry. The contents of Se and Zn in mussel gonads and gametes were found to depend on the stage of the reproductive cycle. In female gonads, Se and Zn concentrations were higher than in male ones. The highest concentration of Se was recorded in eggs: (14.7 ± 2.9) μg·g−1 dry weight (d. w.). In sperm, it was (14.4 ± 1.8) μg·g−1 d. w. Zn content in gonads before spawning was higher than in gametes. In male gonads and in sperm, its values were (27.5 ± 3.7) and (19.3 ± 6.4) μg·g−1 d. w., respectively. In female gonads and eggs, the contents of zinc were (53.6 ± 10.9) and (49.3 ± 8.2) μg·g−1 d. w., respectively. In spring, the mean values of Se and Zn assimilation degree (q) in gonads of the mussel were within 0.1–0.6. The limit values of the alimentary accumulation coefficient (Klim) of Se and Zn ranged 0.6 to 1.4. While spawning, mussels excrete polyunsaturated fatty acids (PUFA), which are probably used by other marine organisms. Up to 56.2 % of PUFA are excreted with sperm, and 48.1 %, with eggs, whereas in larvae this fraction does not exceed 10.2 %. The data obtained indicate that the molluscs assimilate sex hormones, fatty acids, selenium, and zinc to maintain vital processes: prostaglandins are synthesized from PUFA in the body, and testosterone esters are formed from testosterone. Se and Zn, when coupled with proteins, play a key role in the reproduction and formation of larval shells.

Statistical distributions of urban noise levels are influenced by many complex phenomena, including spatial and temporal variations in the source level, multisource mixtures, propagation losses, and random fading from multipath reflections. This article provides a broad perspective on the varying impacts of these phenomena. Distributions incorporating random fading and averaging (e.g., gamma and noncentral Erlang) tend to be negatively skewed on logarithmic (decibel) axes but can be positively skewed if the fading process is strongly modulated by source power variations (e.g., compound gamma). In contrast, distributions incorporating randomly positioned sources and explicit geometric spreading [e.g., exponentially modified Gaussian (EMG)] tend to be positively skewed with exponential tails on logarithmic axes. To evaluate the suitability of the various distributions, one-third octave band sound-level data were measured at 37 locations in the North End of Boston, MA. Based on the Kullback-Leibler divergence as calculated across all of the locations and frequencies, the EMG provides the most consistently good agreement with the data, which were generally positively skewed. The compound gamma also fits the data well and even outperforms the EMG for the small minority of cases exhibiting negative skew. The lognormal provides a suitable fit in cases in which particular non-traffic noise sources dominate.

BackgroundPicrorhiza kurroa has been reported as an age-old ayurvedic hepatoprotection to treat hepatic disorders due to the presence of iridoids such as picroside-II (P-II), picroside-I, and kutkoside. The acylation of catalpol and vanilloyl coenzyme A by acyltransferases (ATs) is critical step in P-II biosynthesis. Since accumulation of P-II occurs only in roots, rhizomes and stolons, uprooting of this critically endangered herb has been the only source of this compound. Recently, we reported that P-II acylation likely happen in roots, while stolons serve as the vital P-II storage compartment. Therefore, developing an alternate engineered platform for P-II biosynthesis require identification of P-II specific AT/s.Methods and results In that direction, egg-NOG function annotated 815 ATs from de novo RNA sequencing of tissue culture based ‘shoots-only’ system and nursery grown shoots, roots, and stolons varying in P-II content, were cross-compared in silico to arrive at ATs sequences unique and/or common to stolons and roots. Verification for organ and accession-wise upregulation in gene expression of these ATs by qPCR has shortlisted six putative ‘P-II-forming’ ATs. Further, six-frame translation, ab initio protein structure modelling and protein-ligand molecular docking of these ATs signified one MBOAT domain containing AT with preferential binding to the vanillic acid CoA thiol ester as well as with P-II., implying that this could be potential AT decorating final structure of P-II. ConclusionOrgan-wise comparative transcriptome mining coupled with reverse transcription real time qPCR and protein-ligand docking led to the identification of an acyltransferases, contributing to the final structure of P-II.

In most mines, methane gas is accumulated in pores inside coal, the highest amount of which is found in coal mines, and methane is the most important polluting gas in underground coal mines. In coal mining operations, coalbed methane is one of the potential hazards that must be extracted to prevent an explosion of the accumulated gas and environmental pollution. One of the mechanisms is using microwave irradiation so that the thermal stress caused by microwave heating generates fractures. In this research, we investigated the most important parameters affecting the electric and thermal fields’ distribution in coal in order to identify the effective parameters that achieve the highest temperature increase rate and to reach the highest impact and efficiency of the system with the least amount of consumed energy. The results of this study show that the most effective parameter on the electric and thermal fields’ distribution within coal is the size of the resonance chamber.

The process of excavation and unloading of a deep subway foundation pit will cause deformation of the surrounding buildings. There are significant differences in building deformation due to different methods of supporting the foundation pit and building foundation forms. This study takes the deep foundation pit project of the station as an example to investigate this difference. A three-dimensional numerical finite element model of a deep foundation pit has been established that considers different types of building foundations (independent foundation, box foundation, and pile foundation). The sensitivity of the two supporting methods of the diaphragm wall and the combined support of isolation pile and diaphragm wall regarding the maximum settlement value of the building, the horizontal inclination value, the slope angle, and the foundation angular distortions were analyzed. Finally, the sensitivity of the length of the isolated pile to the maximum settlement value and the horizontal displacement value of different types of building foundations are discussed. The results show that the combined support method of isolation piles and diaphragm walls has the highest supporting efficiency (93.5% of independent foundations and 42.3% of box foundations) for angular distortions of shallow foundation buildings. The efficiency of pile foundation support is the lowest (31.4%). For the combined support method of isolation piles and diaphragm walls, the maximum settlement value, and the value of horizontal displacement of the building will decrease with increasing the length of isolation pile. When the depth of isolation pile is greater than 24 m, the settlement deceleration rate of the independent foundation and the pile foundation slows down; when the depth of isolation pile is greater than 27 m, the settlement deceleration rate of the box foundation will slow down, and the deceleration rate of the horizontal displacement of the independent foundation and box foundation will slow down.

IntroductionSimulation technology has an established role in teaching technical skills to cardiology fellows, but their impact on teaching trainees to interpret coronary angiographic (CA) images has not been systematically studied. The aim of this randomized controlled study was to test whether structured simulation training in addition to traditional methods would improve CA image interpretation skills in a group of novices to advanced medical trainees.MethodsWe prospectively randomized 105 subjects comprising of medical students (N=20), residents (N=68) and fellows (N=17) from the University of Arizona. Subjects were randomized into a simulation training group which received simulation training in addition to didactic teaching (n=53) and a control training group which received didactic teaching alone (n=52). The change in pre and post-test score (delta score) was analyzed by a two-way ANOVA for education status and training arm.ResultsSubjects improved in their post-test scores with a mean change of 4.6 ± 4.0 points. Subjects in the simulation training arm had a higher delta score compared to control (5.4 ± 4.2 versus 3.8 ± 3.7, p=0.04), with greatest impact for residents (6.6 ± 4.0 versus 3.5 ± 3.4) with a p=0.02 for interaction of training arm and education status.ConclusionsSimulation training complements traditional methods to improve CA interpretation skill, with greatest impact on novice trainees. This highlights the importance of incorporating high-fidelity simulation training early in cardiovascular fellowship curricula.
