Comparison of guideline- and model-based WWTP design for uncertain influent conditions
Authors: Lindblom Erik U. , Samuelsson Oscar
Published: December 2022

In this study, two methods for wastewater treatment plant (WWTP) dimensioning were compared: (1) a traditional guideline-based approach, and (2) a mechanistic model-based approach. The design outputs depended on uncertainties in correlated influent concentrations, which emphasises the importance of uncertainty analysis. The results showed that model-based design could simplify and reduce the time required for uncertainty and sensitivity analysis compared to a conventional design approach, in which the equations are solved manually and iteratively. A benefit of the conventional design approach was the simple interpretation of which factors limited the design capacity. In the end, this study shows the potential, as well as the need for, model-based design of WWTPs.

Authors: Sanjeev Nayanathara O. , Vallabha Manjunath Singanodi , Valsan Aswathy E
Published: December 2022

In this research, zinc oxide (ZnO) nanoparticles synthesized using neem leaf (Azadirachta indica) extract were used as an adsorbent for removing two widely used pharmaceutical compounds acetaminophen (AMP) and sulfadiazine (SDZ). The synthesized ZnO nanoparticles were characterized using SEM-EDS, FTIR, TEM, BET, and XRD analysis. The synthesized ZnO nanoparticles were found to be in the size range of 10 nm with a surface area of 48.551 m2/g. The adsorptive performance of ZnO nanoparticles in both mono-component (MoS) and multi-component system (MuS) was investigated under various operational parameters viz. contact time, temperature, pH, concentration of pharmaceutical compound and ZnO nanoparticles dose. It was observed that the maximum adsorption capacity of ZnO nanoparticles was 7.87 mg/g and 7.77 mg/g for AMP and SDZ, respectively, under the optimum conditions of 7 pH and 2 g/L adsorbent dosage. The experimental data best-fitted with the pseudo-second-order model and Langmuir model, indicating monolayer chemisorption. Further investigation on removal of AMP and SDZ from multicomponent system was modelled using a Langmuir competitive model. The desorption study has shown 25.28% and 22.4% removal of AMP and SDZ from the surface of ZnO nanoparticles. In general, green synthesized ZnO nanoparticles can be utilized effectively as adsorbent for removal of pharmaceutically active compounds from wastewater.

El olvido de la 'sophia'
Authors: Jaffelin Emmanuel
Published: December 2022

La filosofía es una disciplina que no es una ciencia y que es poco conocida por el gran público que ve en ella una forma de reflexión original. Para comprender esta originalidad, debemos recordar el comienzo de la historia de la filosofía que, desde el final de la Antigüedad, abandonó su primer objetivo, a saber, la Sabiduría. Desde el emperador Justiniano que cerró todas las escuelas de filosofía en el año 533 d.C. JC, la filosofía sobrevivió al permanecer como un discurso (logos) desconectado de su acción (praxis); ahora bien, esta praxis era sophia (sabiduría). Consideremos entonces que la filosofía está muerta desde hace 15 siglos y que los filósofos han sobrevivido sometiéndose a la autoridad de turno, primero a la teocracia y por tanto a la Iglesia, luego al Estado y por tanto al Docente. En el primer caso, los filósofos están más interesados ​​en la fe y la santidad que en la meditación y la sabiduría; en el segundo caso, prefieren enseñar y escribir antes que dialogar para desarrollar una forma de vida serena. La filosofía se ha desviado de su objetivo, la Sabiduría. ¡Se trata, por tanto, de revivir la filosofía reabriendo las escuelas que enseñan la sabiduría!.
Burdur Müzesi'nden Erkek Portresi
Authors: Arlı Yaşar
Published: December 2022

Günümüze kadar kaleme alınmayan erkek portresi, Burdur Müzesi’nde korunmaktadır. Yerel malzemeden yontulan portrenin buluntu yeri bilinmemektedir. Arkeoloji dünyasına kazandırmak amacıyla kaleme alınan eserin ilk önce durum ve tanımı yapılmıştır. Kendine has karakteristik özellikleriyle yontulan erkek başı, özel bir portredir. Bu portredeki başa yapışık, uzun ve hacimli saç buklelerinin alın merkezinde çatal motifi oluşturacak şekilde tasarlanması da eserin tarihlendirilmesi açısından oldukça önemlidir. Çünkü Roma İmparatorluk dönemi portre sanatının yorumlanmasındaki en önemli etken hüküm süren imparatorun saç stili ve sanatsal anlayışıyla birlikte eşinin saç modasıydı. İrdelenen eserdeki saç stili de önerildiği dönemin imparator portresiyle karşılaştırılmıştır ve ayrıca bu imparatorun portre tipleri de açıklanmıştır. Böylelikle erkek başının, imparatorun hangi portre tipinden esinlenerek yontulduğu da belirtilmiştir. Traianus’un I. tip portrelerinden esinlenerek yontulan Burdur eseri, imparatorun hükümranlık dönemine verilmiştir (MS 98-117). Benzer saç stiliyle doğrudan Traianus dönemine verilen Burdur eserindeki yüz hatlarının işlenişindeki üslup özelliği de eser için önerilen bu dönemi destekler niteliktedir.

Authors: Peng Ren , Ai Lei , Mei Fangwei
Published: December 2022

Background:

Solvent tolerance is a desired feature of microorganisms for their application
in biotechnology. Organic solvent-tolerant microorganisms are able to thrive in the presence of
organic solvents. Several mechanisms have been proposed to elucidate their intrinsic tolerance to
organic solvents.

Objective:

Membrane proteins related to transporter, signal transduction, and material and energy
metabolism are involved in solvent tolerance. Optimization of the expression level of membrane
proteins and engineering of membrane proteins are utilized to tackle the toxicity caused by organic
solvents.

Results:

Membrane proteins related to transporter, signal transduction, and material and energy
metabolism are involved in solvent tolerance. Optimization of the expression level of membrane
proteins and engineering of membrane proteins are utilized to tackle the toxicity caused by organic
solvents.

Conclusions:

Membrane proteins occupy a strikingly important position in microbial solvent
tolerance. Further research on novel methods in membrane proteins, trade-offs among overexpression
and toxicity of membrane proteins and solvent yield, and a direct relationship between signaling
pathways and solvent tolerance will advance the utilization of organic solvent-tolerant
microorganisms in biotechnology.
Mir-21-5p and Mir-455-5p as Markers for Diagnosis and Prognosis of
Rectal Adenocarcinoma may Reduce Local CD4+ and CD8+ Lymphocyte
Infiltration
Authors: Deng Heng , Shi Haiping , Yuan Xiancang , Zhang Jun
Published: December 2022

Objective:

This study aimed to verify miRNAs and the molecular mechanisms of diagnostic
and prognostic biomarkers for rectal adenocarcinoma.

Methods:

Two miRNA datasets of rectal adenocarcinoma were obtained from GEO and TCGA.
GEO2R tool, Venn diagram, Kaplan-Meier survival analysis, KEGG pathway analyses, DIANA
TOOLS, and Wilcoxon rank-sum test were used for biological information analysis. The diagnostic
utility of miRNAs and immune infiltration of tumors in Chinese patients were validated by RTqPCR
and immunofluorescence analysis.

Results:

MiR-21-5P and miR-455-5p were both found to have a significant correlation with poor
prognosis and higher expression in rectal adenocarcinoma. Besides, the ability to prognosis was
independent of the clinicopathological stage. MiR-21-5P and miR-455-5p were enriched in the
TGF-beta, Wnt, MAKP, and PI3K-AKT signaling pathways. Meanwhile, the high expression phenotype
of miR-21-5P and miR-455-5p decreased CD4+ and CD8+ T cells.

Conclusion:

In summary, we found two significant diagnostic and prognostic miRNAs of rectal
adenocarcinoma via integrated bioinformatics approach and clinical trials, which might decrease
CD4+ and CD8+ T cells.
KRAS Pathway-based Therapeutic Approaches in Pancreatic Cancer
Authors: Althaiban Abdullah , Thyagarajan Anita , Prakash Sahu Ravi
Published: December 2022

Pancreatic ductal adenocarcinoma (PDAC) is one of the highly aggressive malignancies and the leading cause of cancer-related deaths. Despite recent advancements, the overall therapeutic responses in PDAC patients remained relatively low or short-lived. While KRAS is the most frequently mutated proto-oncogene and represents a critical driver, it remains challenging to target all mutant variants. Thus, strategies to target the downstream signaling cascades (RAS-RAF-MEK-ERK) in PDAC were associated with improved response rates. Nevertheless, the activation of other oncogenic cascades, such as PI3K/AKT/mTOR, has also been documented within the same context and implicated in the development of acquired tumor resistance mechanisms and/or reduced efficacy of therapeutic agents. Therefore, an in-depth understanding of overlapping and intersecting pathways is required to overcome the tumor resistance mechanisms to devise novel approaches to enhance the effectiveness of ongoing treatment options. The current review highlights the mechanistic insights from cellular and preclinical studies with particular emphasis on KRAS (i.e., MEK and ERK)-based approaches for PDAC treatment.
Inhibition of p62-Keap1-Nrf2 Pathway Activation by Realgar Promotes
the Inhibition of Esophageal Cancer Cell Proliferation, Migration, and
Ferroptosis
Authors: Zhang Xiaolan , Yang Ruyi , Wang Hongbin , Cao Changxia , Zhao Wenling , Duan Lingyan , Chen Fazhang
Published: December 2022

Background:

Realgar, a Chinese herbal decoction, has been used to treat various types of
tumors with positive outcomes; however, there is a lack of convincing evidence on its use for the treatment
of esophageal cancer (EC). In this study, the role of the p62-Kelch-like ECH-associated protein 1
(Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2) pathway in the regulation of EC cell proliferation,
migration, and ferroptosis in response to realgar was assessed.

Methods:

Different concentrations of realgar (0, 10, 20, 40, 60, 80, and 100 μmol/L) were applied to the
EC cell lines Eca109 and KYSE150. The inhibition rate and half-inhibitory concentration (IC50) were
determined using the Cell Counting Kit-8 (CCK-8) method. Subsequently, the cells were treated with
realgar (1/2IC50, IC50, 2IC50). Cell migration was measured using the scratch assay, and cell invasion
was measured using the transwell assay. The mRNA expression of p62, Keap1, and Nrf2 was measured
by quantitative real-time polymerase chain reaction (qRT-PCR), and the protein expression of p62,
Keap1, Nrf2, matrix metalloproteinase (MMP)-2, MMP-9, E-cadherin, Slug, N-cadherin, and vimentin
was measured by Western blot. The control, 2IC50, shRNA-NC, shRNA-p62, 2IC50 + shRNA-NC, 2IC50
+ shRNA-p62, shRNA-Keap1, 2IC50 + shRNA-Keap1, and 2IC50 + shRNA-p62 + shRNA-Keap1 groups
were defined. The CCK-8 method was used to measure the cell inhibition rate, and the clone formation
assay was used to measure the clone formation ability. Moreover, the scratch assay was used to detect
the cell migration ability, and the transwell assay was used to detect the cell invasion ability. Transmission
electron microscopy was used to observe the mitochondrial morphology, Prussian blue staining was
used to observe the intracellular iron particle distribution, and flow cytometry was used to detect changes
in intracellular reactive oxygen species. In addition, qRT-PCR was performed to detect p62, Keap1,
Nrf2, and glutathione peroxidase 4 (GPX4) mRNA expression, and Western blot was performed to detect
p62, Keap1, Nrf2, E-cadherin, Slug, N-cadherin, and GPX4 protein expression.

Results:

Realgar inhibited Eca109 and KYSE150 cell proliferation in a time- and concentrationdependent
manner. It also significantly inhibited the migration and invasion of Eca109 and KYSE150
cells and affected the mRNA and protein expression of p62, Keap1, and Nrf2. In response to realgar,
low p62 expression inhibited the proliferation, migration, and invasion of Eca109 and KYSE150 cells,
as well as ferroptosis induction.

Conclusion:

The findings demonstrate that inhibiting the p62-Keap1-Nrf2 signaling pathway promotes
the inhibitory effects of realgar on EC cells.
Survival and Analysis of Predictors of Mortality in Patients Undergoing Hemodialysis in a Rural Hospital in Puducherry, India: A Retrospective Cohort Study
Authors: Ravi Kumar P. , Vinayagmoorthy V. , Dongre Amol , Deshmukh Pradeep
Published: December 2022

Background:

Despite the advent of dialysis technology, the survival of patients on hemodialysis (HD) is not encouraging. There is little information available regarding the prognostic factors of HD, its population characteristics, or outcomes in India.

Objectives:

We attempted to describe the profile of patients on HD, estimate the mean days of their survival and to determine the various factors associated with their survival.

Materials and Methods:

It was a retrospective cohort study conducted on patients who were on maintenance HD, registered during the five-year period between 1st January 2014 and 31st December 2018 in a tertiary care teaching hospital in Rural Puducherry, South India. Demographic, hematological, biochemical, electrocardiographic, echocardiographic parameters and death during follow-up were extracted from the dialysis database after de-identification. The survival rate was calculated using Kaplan- Meir Curves and Cox Regression analysis was done to estimate the adjusted hazard ratio.

Results:

The median survival of the 229 eligible patients on HD was 819 days. Cardiac pathology accounted for 25.7% of those deaths and 33.9% was sudden death. Adjusted Cox proportional model showed the presence of Left Ventricular Hypertrophy (LVH) (HR: 78.1), increase in phosphorus (HR: 1.26), decrease in haemoglobin (HR: 0.78), and decrease in serum albumin (HR: 0.52) were significant bad prognostic factors.

Conclusion:

Screening for LVH, anemia, hypoaluminemia and hyperphosphatemia amongst HD patients and managing them to prevent these bad prognostic factors has the potential to improve their survival.
Study on Microwave-assisted Reduction of Pyrolusite
Authors: Liu Dongjie , Du Jinjia , Dai Qingqing , Zhou Junwen
Published: December 2022

Manganese is a vital metal resource, and increased consumption of manganese is leading
to the shortage of high-grade manganese ore resources. However, a large number of low-grade
manganese ore resources ((Mn<30%) accounts for about 60% of the total manganese resources)
have not been effectively utilized because of the lack of efficient industrial utilization methods.
Researching new technologies for reducing low-grade pyrolusite is an urgent problem to be solved.
Microwave is an effective and environmentally friendly heat source widely used in mining, metallurgy,
and chemistry. Different substances have different dielectric constants. The difference in
dielectric constant affects the absorption rate of substances, resulting in different heating rates for
different substances when heated by microwaves. Microwave is widely used in the metal smelting
process because of its unique heating method. So far, few works have been done to verify that
microwave heating can effectively promote the reduction of pyrolusite. This article summarizes
some current methods of reducing low-grade pyrolusite and compares them with the method of
reducing pyrolusite by microwave heating. In addition, this article introduces the principle of microwave-
enhanced reduction of pyrolusite and discusses the opportunities and challenges faced by
microwave heating technology in its subsequent development. The aim is to analyze and study the
promoting effect of microwave heating technology on the reduction of pyrolusite, further improve
the utilization of low-grade pyrolusite, and provide new methods and approaches for the comprehensive
utilization of mineral resources and provide assistance in industrial production.

Published: December 2022

Aims/Objective:

The current study evaluates the effectiveness of a blended
tri-solvent system composed of monoethanolamine (MEA), diethanolamine (DEA), and
piperazine (PZ) for removing the carbon dioxide (CO2) from the stored gas reservoir.
The developed system is intended to be both environmentally benign and productive.

Methods:

The CO2 absorption was carried out for the total solvent (5, 10, and 15%
v/v), during the course of three temperature ranges (20, 25, and 30°C) while maintaining
the reservoir pressure of 1.5, 2, and 2.5 bar. The fraction of DEA: MEA has been
restricted to 0.2, 0.5, and 0.8, with simultaneous loading of anhydrous PZ ranging
from 0 to 2 gm. and agitation speed for step intervals of 300, 600, and 900 rpm. For
the purpose of investigating the synergetic effects of the process parameters on the
rapid absorption of CO2 (ξ) and the initial CO2 absorption rate (ε0), Box-Behnken
Design (BBD) of response surface methodology (RSM) has been exploited. The design
of experiments (DoE) assisted artificial neural network (ANN) and metaheuristic
approach of hybridising ANN-whale optimization algorithm (WOA) was also developed
and utilised to train and test the developed model. Three optimization models based on
RSM, DoE-WOA and ANN-WOA were compared. Under the optimized operating conditions
pertaining to DoE, DoE-WOA and DoE-ANN-WOA, (ε0 = 3.340, 3.460 3.513
gm./min-250 mL) and (ξ = 17.114, 18.069, 18.145 gm./250 mL) were obtained.

Results:

The hybridised DoE-ANN-WOA shows promising results in correlation with
the experimental outcomes having error % for ε0 & ξ of 0.790 & 1.31.

Conclusion:

The DoE-ANN-WOA tends to be selected to predict the optimal absorption
conditions as compared to other optimization techniques used in current article.

Published: December 2022

This article is reviews the application of foreign law by Indonesian courts as governed by the Indonesian Private International Law (PIL). The review is based on Acts and regulations related to PIL, case-laws, and text-books on PIL. The result demonstrates that Indonesian judges often do not implement the principle of iura novit curia in the application of foreign law; ignore foreign elements in their cases; and keep applying Indonesian law even though the rules of Indonesian PIL lead to the foreign law. Therefore, the Bill of Indonesian PIL shall be passed and enacted soon so that there are no more excuses by Indonesian courts not to apply foreign law. Indonesian courts including the Supreme Court, should have a special unit within their system that can provide judges with information on and translation of foreign law. In addition, it is necessary to establish international cooperation regarding exchange of information on foreign law between Indonesia’s Supreme Court and other countries’ Supreme Courts.

Authors: Muhtasar Iqbal Maulana , Sholichin Moh. , Asmaranto Runi
Published: December 2022

Penambangan batubara oleh PT.Kaltim Prima Coal (KPC)Â  merupakan penambangan terbuka, sehingga dapat menimbulkan hilangnya bentuk permukaan bumi, meninggalkan lubang-lubang besar di permukaan bumi, erosi, sedimentasi, maupun penurunan produktivitas tanah. Oleh karena itu diperlukan reklamasi dan rehabilitasi lahan bekas tambang. Dalam proses reklamasi pasca tambang dibutuhkan spesifikasi khusus agar hasil dari reklamasi sesuai dengan yang diharapkan. Faktor-faktor erosi yang memenuhi persamaan USLE dapat diolah dengan mudah menggunakan bantuan Sistem Informasi Geografis. Dari hasil perhitungan pada Pit Pinang South PT.KPC, didapatkan laju erosi 32,62 (ton/ha/tahun), daerah yang mengalami erosi sangat ringan seluas 27,26 ha (35,12%), erosi ringan seluas 27,89 ha (35,94%), erosi sedang seluas 20,60 ha (26,54%), erosi berat seluas 1,62 ha (2,08%), dan erosi sangat berat seluas 0,21 ha (0,27%). Berdasarkan perhitungan SDR, didapatkan hasil sebesar 1440,8 ton/tahun, sedangkan perkiraan besar perhitungan sedimen secara aktual didapatkan nilai sebesar 2223,6 ton/tahun. Maka didapati hasil SDR (931,3 ton/tahun) < hasil aktual (2223,6 ton/tahun). Hal tersebut dikarenakan hasil perhitungan SDR menggunakan nilai erosi yang diperoleh dari metode USLE yang merupakan pendugaan laju erosi sedangkan dalam perhitungan sedimentasi aktual berdasarkan dari perhitungan secara langsung dan hasil laboratorium PT.

Quantitative description of the effect of slag surface area on its reaction kinetics in sodium silicate-activated materials
Authors: Hamdan Abdelrahman , Kim Taehwan , Hajimohammadi Ailar
Published: December 2022

The effects of chemical oxides and the surface area (SA) of slags on the initial reactivity of alkali-activated materials (AAMs) are coupled. It is well known that the reactivity of slag in AAMs is impacted by the SA, however, a quantitative measure of this effect was not provided in previous studies. For a proper understanding of the effect of slag chemistry on the reaction kinetics of AAMs, a quantitative description of the slags SA's effect is required. The reaction kinetics in the activated slags were monitored using isothermal calorimetry. The SAs of the pulverised slags were linked to the time-to-reach-the-main-peak (TTRP) of the reaction, the slope of the acceleration part of the main peak, and the total heat at one, three, and seven days. A 100% relative increase in SA caused a ~51%-75% relative decrease in TTRP. The slope of the acceleration stage also considerably increased with the SA of the slags. However, the effect of the SAs on the total heat was only distinct up to three days and then considerably reduced at seven days. The result of this study indicates that the effect of SA on the initial reactivity of AAMs cannot be simply considered using the proportional contribution. The outcome of this study can provide a promising measure to decouple the effects of SAs and the chemical compositions of slags on the reaction kinetics of AAMs by providing quantitative results for the effect SAs.

Published: December 2022

Iatrogenic aortic dissection during coronary interventions is a rare complication and has heterogeneous management in the reviewed literature. We report a case of acute aortic syndrome of traumatic etiology, during a percutaneous coronary procedure, with its management, intra-hospital evolution, and one-year follow-up. A 65-year-old female who, during a percutaneous coronary intervention, presented an endothelium trauma of the left main artery's aorta-ostial transition by the tip of the guide catheter, leading to aortic dissection and occlusion of the left main artery with hemodynamic deterioration of the patient. The left main artery's flow was restored with drug-eluting stent implantation leading to a successful sealing of the false lumen with consequent hemodynamic stabilization. Immediate post-procedure transthoracic echocardiography showed a competent aortic valve. The patient evolved favorably and remains asymptomatic after one year.

Terahertz time-domain spectroscopy (THz-TDs) has been used to record the resonant frequencies of plasmon oscillations excited in samples of heterostructures with three InGaN/GaN quantum
wells (QWs) by laser pulses with a duration of 130 fs in the temperature range from 90 to
170 K. Fast Fourier transform (FFT) of the time dependence of the electric field of THz pulses
made it possible to obtain the frequency spectra of the power and phase shift of THz radiation, the interpretation of which made it possible to estimate the pulse relaxation time, mobility and
effective mass of two-dimensional electron gas (2DEG) in the heterostructures.
Using a series of frequency spectra of the power and phase shift of THz radiation, the temperature dependences of the effective mass and relaxation time of the 2DEG pulse were obtained. Mobility value
2DEG obtained by the THz-TDs is in good agreement with the data of Hall measurements.

Методами спектроскопии EXAFS и XANES были оценены содержание металлических ионов и их валентное состояние для трех составов NixCuyMn3-x-yBO5. Во всех трех составах содержание меди y не превысило 0.25; в третьем составе часть ионов марганца вошли в соединение не только в трехвалентном, но и в двухвалентном состоянии. Подробное исследование магнитных свойств показало, что во всех составах наблюдается два магнитных перехода: один в районе 60-75 K, а второй в районе 10 K. На основании вычисленных в рамках эмпирической модели обменных взаимодействий были определены температуры магнитного упорядочения для двух- и трехподрешеточного магнетика и сделано предположение, что магнитный переход в районе 60-75 K связан с упорядочением магнитных моментов в позициях 2 и 3. Ключевые слова: людвигиты, магнитный фазовый переход, косвенные обменные взаимодействия.

The results of calculating the dielectric and optical characteristics of solid polymorphic phases of water—ices Ih, III and lattices of hydrates sI, sH—are presented. Static dielectric tensors εik and complex frequency-dependent tensors εik(ω) are calculated for these materials. It is shown that, in terms of optical properties, the crystal lattices Ih, III, and sH are uniaxial, the tensor components εxx(ω) and εyy(ω) coincide for them, and the hydrate lattice sI is isotropic. Based on the calculated frequency-dependent dielectric functions εik ′ (ω) and εik ′′ (ω), important optical characteristics were obtained: reflection R(ω), absorption a(ω), loss function L(ω), refractive indices n(ω) and k(ω). Comparison of the dielectric and optical spectra of the sI and sH gratings with the known spectra for methane hydrate sI revealed a broadening of the spectra in the high-energy direction. For the unfilled hydrate sI, a reflection peak was found at an energy of 17.3 eV, the appearance of which is associated with a change in the electronic structure of the crystal in the absence of a methane molecule. Qualitative agreement is obtained between the reflection spectra R(ω) and the functions εik ′ (ω), εik ′′(ω), calculated by quantum mechanical simulation, with experimental spectroscopy data for hexagonal and amorphous ices.

Background: One in four mothers experience unwanted pregnancy. It causes great risks for mothers and children, such as malnutrition, neglected, violence and even death. During pregnancy, a woman is expected to take the initiative and change her behavior by taking adequate care. Antenatal care is a part of maternal and child health services that are vital in early detection and monitoring of fetal well-being as an efforts to improve the health of mothers and babies during pregnancy, childbirth and postpartum. The mother's intention towards her pregnancy, whether desired or not, is related to the mother's behavior during pregnancy. Unintended pregnancy can obstruct the achievement of adequate antenatal care..

Objectives: This study aims to determine the relationship between unintended pregnancy and antenatal care behavior

Methods: This study used a cross-sectional design with the secondary data from 2017 Indonesian Demographic Health Survey. The dependent variable in this study was antenatal care behavior which is a composite of the first antenatal visit, frequency of antenatal visit and iron consumption. There were 14.223 women of childbearing age 15-49 years which eligible for this study’s criteria. The collected data was analyzed with chi square and logistic regression models of risk factors test

Results: Mothers with unintended pregnancies have a bigger opportunity to do unhealthy antenatal care behavior (OR =  2.338: 95% CI 1.707- 3.203) compared to intended pregnancies. The effect of unintended pregnancy on antenatal care behavior varies according to maternal age (OR- 1.267: 95% CI 1.034-1.553), parity (OR= 0.579: 95% CI 0.430-0.780) and residency (OR= 1.490: 95% CI 1.226- 1.811).

Conclusions: There is a relationship between unintended pregnancy and antenatal care behavior. Mothers with unintended pregnancies is 2.338 times more likely to have unhealthy antenatal behavior care. We also found that this effect differs according to the maternal age, parity and residency.
