The Effects of Myoma and Uterine Preserving Procedures for Myoma on Pregnancy Outcomes
Authors: Um Gi Soo , Ko Hyun Sun
Published: May 2022

Uterine myomas are the most common benign tumors in reproductive aged women. There have been concerns about fertility and obstetric complications in pregnant women with myomas. Currently, maternal age for pregnancy is increasing, and uterine-preserving therapeutic procedures of uterine fibroids such as myomectomy, high-intensity focused ultrasound (HIFU), or uterine artery embolization (UAE) have increased. However, it is unclear whether those treatments can improve fertility and pregnancy outcomes. Recent data suggest that pregnancies after uterus-preserving procedures are associated with obstetric complications such as cesarean section, placenta previa, preterm labor, premature birth, and low birth weight. The biggest obstetric concern in pregnancies after uterine-preserving procedures is uterine rupture during pregnancy, which can threaten the survival of fetuses. Moreover, uterine rupture after myomectomy is more likely to occur before labor onset. Most international guidelines suggest that myomectomy be considered for a woman with uterine myomas who has undergone several unsuccessful in vitro fertilization cycles despite appropriate ovarian response and good-quality embryos or for a woman with symptomatic myomas. In addition, HIFU or UAE treatments are relative contraindications in women with a future pregnancy plan, because there are limited data about associated pregnancy outcomes, and UAE can affect fertility after the procedure. The risks of uterine rupture and of obstetric complications in pregnancies after myomectomy should be discussed in affected women with a future pregnancy plan.
A Review on the Postpartum Depression Management Systems in Korea
Authors: Kim Hee-Sun , Park Hyun Soo , Choi Anna
Published: May 2022

Pregnancy is a period of various hormonal changes; furthermore, since pregnancy and childbirth itself are major stressors, pregnant women are inevitably vulnerable to psychiatric disorders. The emotional changes during postpartum blues, the anxiety experienced by about half of all mothers in the first week after childbirth, are usually temporary; they peak 4–5 days after delivery and then normalize after 10 days. Postpartum depression, however, is a disease that occurs frequently in mothers, and its incidence has been increasing due to sociocultural changes. In Korea, interest in postpartum depression is growing due to the government's efforts to promote maternal health. The national policy provides support to overcome the low fertility rate and to change social perceptions, but there is still insufficient medical intervention for mothers at high risk of postpartum depression. Considering the negative effects of mental health disorders on mothers and childrearing, we propose plans for more active, early intervention and the prevention of prenatal and postpartum depression.

Authors: Park Ye Ju , Kim Jae Woo , Ahn Ki Hoon
Published: May 2022

Purpose: Since the division of the Korean Peninsula into South and North Korea in 1948, the gaps in the medical system and the socioeconomic status between these 2 countries has expanded. The purpose of this study was to analyze the distribution of different areas of research, as well as the types of research that was conducted in the North Korean medical journal, ‘Pediatrics, Obstetrics and Gynecology.’ This study aimed to specifically investigate the medical research status of healthcare in women and children.Methods: This study analyzed a total of 949 papers that were published in the North Korean medical journal, ‘Pediatrics, Obstetrics and Gynecology.’ Papers from January 2015 to December 2019 were included. For the analysis, the 8th Korean Standard Classification of Diseases, disease name, subspecialty classification, and research classifications were extracted from the papers.Result: Of the 949 papers included in the analysis, 495, 366, and 88 studies were conducted in the major fields of obstetrics and gynecology, pediatrics, and on breast surgery, respectively. Within the field of obstetrics and gynecology, the most studied subspecialties were maternal and fetal medicine, general gynecology, and gynecologic oncology. To a lesser extent, the following subspecialties were reported: gynecologic endocrinology (6.7%), infertility (6.3%), and urogynecology (approximately 1%).Conclusion: Although North Korean papers differ from those published worldwide (due to government intervention), they are still a useful source of information as they are easier to access than alternative data sources. The results from this study have implications for understanding the distribution of research on different areas of healthcare, as well as the burden of healthcare in North Korea.

Authors: Bright Katherine S , Stuart Scott , Mcneil Deborah A , Murray Lindsay , Kingston Dawn E
Published: May 2022

Background

Prenatal mental health is a global health concern. Despite the far-reaching impact of prenatal mental health issues, many women do not receive the psychological care they require. Women in their childbearing years are frequent users of the internet and smartphone apps. Prenatal women are prime candidates for internet-based support for mental health care.

Objective

This study aimed to examine the feasibility and acceptability of internet-based interpersonal psychotherapy (IPT) for prenatal women.

Methods

Semistructured interviews were conducted with women who had received internet-based IPT modules with guided support as a component of a randomized controlled trial evaluating the scale-up implementation of a digital mental health platform (The Healthy Outcomes of Pregnancy and Postpartum Experiences digital platform) for pregnant women. Qualitative thematic analysis was used to explore and describe women’s experiences. Data were analyzed for emerging themes, which were identified and coded.

Results

A total of 15 prenatal women were interviewed to examine their experiences and views on the feasibility and acceptability of internet-based IPT modules. Participants found the content informative and appreciated the ways in which the digital mental health platform made the IPT modules accessible to users. Participants voiced some differing requirements regarding the depth and the way information was presented and accessed on the digital mental health platform. The important areas for improvement that were identified were acknowledging greater depth and clarity of content, the need for sociability and relationships, and refinement of the digital mental health platform to a smartphone app.

Conclusions

This study provides useful evidence regarding treatment format and content preferences, which may inform future development. It also provides research data on the feasibility and acceptability of web-based applications for prenatal mental health care.

Authors: Meutia Alfa Putri , Santoso Budi Iman , Hestiantoro Andon , Wuyung Puspita Eka , Prihartono Joedo , Boediono Arief , Djusad Suskhan , Fauzi Amir , Budinurdjaja Pribakti
Published: May 2022

Background

Mesh-augmented surgery with polypropylene meshes (PPMs) is often used in urogynecology and pelvic reconstructive surgery. However, the various complications that arise from its integration process have resulted in a decrease in the number of mesh-augmented surgeries performed worldwide. An approach to improving mesh-tissue integration is coating PPMs with anti-inflammatory and wound-healing molecules, such as platelet-rich plasma (PRP), which is a component of biotechnologies that are capable of accelerating wound healing. Estrogen is also known to have a beneficial effect on wound remodeling; therefore, a hypoestrogenic status may have negative implications for wound healing. The mechanism of how PRP plays a role in wound remodeling, especially among individuals in a hypoestrogenic state, has not been fully described until now.

Objective

Our aim is to investigate the impact of applying PRP to PPMs in hypoestrogenic rabbit models.

Methods

Our study will be a randomized controlled trial involving hypoestrogenic rabbit models. Samples were categorized into either the PRP group or the PPM group (1:1 ratio), with a minimum sample size of 16 in each arm, via simple random sampling. All samples were put into a hypoestrogenic state via bilateral oophorectomy. After confirming a decrease in estradiol level, the meshes were implanted in the vesicovaginal space. The samples were euthanized on the 14th, 28th, or 90th day of the surgery. The mesh-tissue integration process will be analyzed based on inflammatory parameters (inflammatory infiltrate, interleukin-17, and interleukin-1B expression); angiogenesis (CD31 expression); and collagen deposition, which will be assessed by using Masson trichrome staining.

Results

Our study is in the protocol development stage. A preliminary study regarding its feasibility, including the feasibility of the preparation of hypoestrogenic rabbit models, mesh implantation in the rabbits’ vesicovaginal spaces, the PRP and amnion scaffold, started in February 2022. The results of our study are expected to be available by the end of 2022.

Conclusions

Our randomized controlled trial is designed to provide high-quality evidence on the effect of applying a PRP-decellularized amnion scaffold to PPMs in the vesicovaginal spaces of hypoestrogenic rabbit models.

COVID-19’s impact on digital health adoption: The growing gap between a technological and a cultural transformation (Preprint)
Authors: Mesko Bertalan
Published: May 2022

BACKGROUND

In the 21st century, healthcare has started going through major changes. Due to the rising number of patients with chronic conditions; an increased access to new technologies, medical information and peer support via the Internet; and the ivory tower of medicine breaking down, a cultural transformation called digital health has begun.

OBJECTIVE

To analyze COVID-19's impact on the cultural and technological adoption of digital health.

METHODS

Opinion piece

RESULTS

It seems that technologies become available at an unprecedented rate, and the cultural transformation is the component that will take time. Learning to deal with the equal-level partnership takes more time than learning to use a sensor or smartwatch,
Still, if the technological and cultural transformations can take place almost simultaneously, there is a big chance that the core elements of care such as empathy, compassion and relationships based on trust will remain intact.
However, clinical reality does not reflect this optimism. Healthcare is overwhelmed worldwide, physicians rapidly burn-out under the immense pressure, patients with chronic conditions lack access to care, treatments get delayed and medical professionals do their best to maintain the system.

CONCLUSIONS

Nevertheless, if we do it well enough now, we can spare a decade of technological transformations and bring that long-term vision of patients becoming the point-of-care to the practical reality of today. This is a historic opportunity we might not want to waste.

Authors: Rebelo Artur , Ronellenfitsch Ulrich , Partsakhashvili Jumber , John Endres , Sekulla Carsten , Krug Sebastian , Rosendahl Jonas , Michl Patrick , Ukkat Jörg , Kleeff Jörg
Published: May 2022

BACKGROUND

Endovascular aortic repair (EVAR) is nowadays the standard procedure in treating patients diagnosed with abdominal pathologies with suitable anatomy. Open surgery remains an option mostly for patients not suitable for endovascular surgery. Colonic ischemia is an important and life-threatening postoperative complication of these procedures.

OBJECTIVE

The aim of this study is to evaluate the clinical value and safety of performing a planned sigmoidoscopy and biopsy for detection of colonic ischemia in patients undergoing elective aortic surgery. We also aim to develop prediction scores which could identify patients at risk for CI and facilitate their timely treatment.

METHODS

The trial is designed as a prospective study. The decision for aortic surgery is taken and eligibility for these procedures is ascertained according to current guidelines. Afterwards, screening of the patient for the remaining inclusion and exclusion criteria takes place. If eligibility for study inclusion is confirmed, the patient is informed about the aims of the study and all study-specific procedures (sigmoidoscopy and biopsy) and asked to provide informed consent. We assume that the rate of colonic ischemia diagnosed within 48 hours after the operation would be increased by 10% by means of sigmoidoscopy in asymptomatic patients. 120 cases undergoing sigmoidoscopy would allow for a comparison to the incidence of colonic ischemia after aortic surgery reported in the literature (5%) with alpha = 5 % and the statistical power (1-beta) = 80%.

RESULTS

This study will provide insight on the clinical value and safety of performing a sigmoidoscopy and biopsy for detection of colonic ischemia in patients undergoing elective aortic surgery. If the present study showed that sigmoidoscopy can be performed safely and is effective for diagnosing colonic ischemia in these patients, this could result in its routine implementation in both elective and emergency settings.

CONCLUSIONS

If the present study will show that sigmoidoscopy can be performed safely and is effective for diagnosing colonic ischemia in these patients, this could result in its routine implementation in both elective and emergency settings.

Hasil tersebut menunjukkan bahwa kadar besi sampel air limbah tidak melebihi batas ambang air limbah pertambangan.
STRUGGLING AGAINST STEREOTYPE: A STUDY OF MASCULINITY IN AMERICAN GAY TV SERIES
Authors: Rudy Rudy
Published: May 2022

This study aims to analyze the concept of masculinity in the gay male community and identify the image of masculinity in gay men shown in the American gay television series. Data for this qualitative research was gathered from several American gay TV series in the 2000s. The data analysis process involved representation theory in interpreting the dialogs and the scenes in the television series. The study found that masculinity does not always have to be associated with physical strength and heterosexuality because there are other essential aspects such as the ability to achieve success and to meet the needs of life that can be used to conceptualize masculinity. It also revealed that American gay television series frequently showed the representation of masculinity in gay characters to reject the stereotype through images such as physical strength in sports, attractive physical appearance, profession, and ability to achieve success.

Authors: Adhitya Galant Nanta , Rosmawati Devi , Fainnayla Tiara Salma
Published: May 2022

A novel coronavirus was found on December 2019. WHO named the disease caused by this virus COVID-19. The respiratory virus has been spreading rapidly, causing a global pandemic. To prevent infection, governments all over the world compel their citizens to maintain physical distance and stay at home. Having to do all activities, including working and studying, from home and not being able to gather with family and friends, who do not live in the same household, took a toll on people’s mental health. They thus relied on entertainments accessible at home to avoid boredom and stress. An entertainment medium seeing a significant increase in users is streaming services. Besides offering post-launched movies, TV series and TV show, every streaming service nowadays also produces original contents. Netflix, for example, created a stand-up comedy special starring Kevin Hart, called Zero F**ks Given. The researchers thus aim to analyze the verbal humor Hart uses to incite laughter. The data are collected by watching the show on Netflix website and note-taking its subtitle. Using descriptive qualitative method, this research employs Richard Shade’s theory on humor classification as well as Herbert Paul Grice’s theory on implicature. The findings show there are only 7 out of 12 verbal tumor types, with satire being the most frequent one. Additionally, Hart uses conversational implicature more as it is greatly suitable with satire in inciting laughter.
La constitucionalización del derecho internacional de los derechos humanos y la limitación de su alcance vía interpretación constitucional en México
Authors: Cervantes Alcayde Magdalena
Published: May 2022

El artículo refiere la incorporación del derecho internacional de los derechos humanos vía reconocimiento constitucional en el caso mexicano y su acompañamiento por la interpretación que el tribunal constitucional de dicho país ha venido realizando sobre su significado y alcance. Para la autora, la Suprema Corte de Justicia de la Nación ha realizado interpretaciones diversas, sin aclarar su sentido para la labor jurisdiccional, con lo cual dificulta su aplicación; así como interpretaciones que limitan su alcance, contrarias al principio pro persona reconocido como pauta de interpretación en el marco constitucional. Partiendo de la idea de que la integración del tribunal constitucional mexicano determina el sentido de las interpretaciones, la autora adelanta que en el futuro próximo no se tomarán decisiones progresivas en materias relevantes para los derechos humanos.
A Smart Helmet for Secure Monitoring of Miner Data to Improve Safety
Authors: Khattar Prerna
Published: May 2022

Abstract: In recent times, mining has been a dangerous activity taking a severe toll on the lives of miners. Underground mining hazards include gas poisoning, suffocation, roof collapse, and gas explosion. This project aims to develop a smart helmet based on Zigbee wireless technology to build wireless sensor networks for real-time surveillance and monitoring hazardous gases and abnormal levels of temperature and humidity in the mine. These three parameters are continuously being detected using the gas sensor(s), temperature and humidity sensor, and if the predefined limit is crossed, a buzzer and LED will be initiated. Two infrared sensors, one inside and one on the surface of the helmet, are placed to check if the helmet is properly placed and to detect collision from falling debris, respectively. These values are continuously being transmitted to the control room for monitoring. In case of any hazardous situation, the led and buzzer are activated in the control room as well as on the miner’s helmet. The helmet is powered by the energy generated from piezoelectric sensors placed in the miner’s shoes, which work on the principle of vibration detected from the miner’s movement. The safety measures included in our project can drastically help us avoid mining accidents and thus saving invaluable lives.

Published: May 2022

Abstract: This paper aims to promote the use of the LSTM, random forest Regression & Linear Regression algorithm to predict stock prices of India and to compare their accuracy. These are machine learning algorithms used for historical real-time gold prices. The Historical Gold data we made with reference of www.goldpriceindia.com. The full source code of the project was written via Python. It is thought that the LSTM model are more compatible than the Linear Regression and Random Forest model for the Gold price Prediction forecasting model. Gold is a valuable metal and has been historically owned and traded as an asset /commodity. The price of Gold is often a derivative of the investor’s sentiment and perception of other asset classes (real estate, equities, commodities, futures and cash equivalents) as Gold has very little fundamentals of its own. Our project is aimed at studying the relationship between gold price, selected economies and various market variables to try and accurately predict the future price of gold using Machine Learning algorithms.

Stress Responses of Sugar Beet to Different Drought Regimes
Authors: Loho Lama , Jena Nandita , Mohanty Saroj Kumar
Published: May 2022

Abstract: Water deficit (drought) stress is a major environmental factor limiting the production of crops. To evaluate the tolerance performances, a pot experiment was conducted using tropical sugar beet under different regimes of drought stress duration of 5, 10, 15 and 20days (T1, T2, T3, T4)with day temperature of 36-40°C. After subjected to various stress durations all plants were re-watered regularly till harvest. Significant reduction observed in plant fresh and dry weight, shoot fresh weight and dry weight, root fresh weight and dry weight and shoot: root ratio over control. Reduction in photosynthesis expressed in terms of decrease in Chl a, Chl b, and total chlorophyll in leaves of sugar beet was noticed significantly. Proline which acted as osmoprotectant and induced tolerance, gradually increased with increase of stress duration of 5days (2.024µg.g-1 ) to 20days (7.398µg.g-1 ). Total soluble carbohydrate contents in stressed plants also increased against control, where starch accumulation increased up to 15days stress and then declined significantly at 20days of water withholding showing its mobilization towards root growth and higher value of adaptability. The reduction in growth performance somehow recovered after re-watering of the stressed plants which is observed at harvest. This stress impact is managed to some extent in their tuber yield values from moderate to severe stress treated plants i.e.T2(25.817t.ha-1 ) and T4(13.918t.ha-1 ). At moderate stress, sugar beet plants showed tolerance and adaptation by triggering accumulation in roots. Hence it may be concluded that sugar beet crop is relatively tolerant to drought, but is very sensitive during growing stage. Keyword: Drought, Stress, Tolerance, Tuber yield, Proline

Abstract: Medical demands during the COVID-19 pandemic have triggered a grave shortage of medical-grade personal protective equipment (PPE), especially, N95 respirators. N95 respirators are critical for the personal protection of medical providers and others when being exposed to individuals with infections caused by the SARS- CoV-2 coronavirus. To address the shortage of PPE Kit & N95 respirators, innovative methods are needed to decontaminate coronaviruses from N95 respirators & PPE Kit, allowing them to be safely reused by healthcare workers. For this research, we use a commercial ozone disinfecting cabinet to examine the efficacy of ozone-based disinfection of a conservative surrogate virus for SARS-CoV-2/Ultra Violet radiation, Chlorination, washing with soap and heating are some methods of sterilizing. Ultra Violet light is thebest sterilizing and disinfectant agent, used for domestic as well as clinical purpose. Food packets, books, stationery, medical equipment’s, toys, electronic gadgets like mobile phones, laptops, wrist watches, etc. can be sterilized with UV radiation whereasother methods of sterilization cannot be used. UV light does not release any waste andis eco-friendly, if used in a controlled manner. UV radiation is a range of electromagnetic waves with shorter wavelength (high frequency and energy). The wavelength from 100-280 nm known as UV-C isthe best disinfectant used for purifying water, air, sterilizing vegetables and surgical equipment’s. Research has shown that UV-C wavelength can kill harmful fungi, protozoa, bacteria and viruses like SARS- CoV-2 Virus. The article describes the construction of a low-cost UV-C Sterilizer Boxwhere UV radiation is taking place in a closed environment. Safety features are also incorporated to prevent humans from UV light exposure. The germicidal property of ultraviolet-C is well known. This review will cover the most commonly described methods for sterilization of PPE Kit, namely, ultraviolet germicidal irradiation. These techniques have been tested previously and have demonstrated efficacy in reducing or inactivating viral and bacterial pathogens, although testing against SARS-CoV-2 specifically has not been done. Moreover, it must be emphasized that proper disposal after a single use is still ideal under normal circumstances.

The subjects of this study were 15 Year 10 students of Taxation Vocational High School majoring in business and management taken based on learning interests. This study employed a descriptive method with tests and questionnaires as the instruments. The outcomes confirmed that students with high interest in learning made 13 mistakes, while 19 and 20 errors were for students with moderate and low interest in learning, respectively. Of all the errors, based on the student's interest in learning, conceptual and procedural errors were the most common errors (20 errors each). It can be concluded that the more positive students’ attitudes, the lower the errors they make, especially on conceptual errors.
Sensibilidades queer e estética neobarroca nas dobras fotográficas
Authors: Oliveira Junior Ribamar José de , Gil Huber Jaramillo
Published: May 2022

Este estudo analisa as sensibilidades queer à medida que emergem nas obras fotográficas de Severo Sarduy (Cuba, 1937-1993), Pedro Lemebel (Chile, 1952-2015), Alair Gomes (Brasil, 1921-1991) e Hudinilson Júnior (Brasil, 1957-2013). Ao fazê-lo, consideramos nas imagens o que pode ser visto como um barroco queer. Entre a beleza, o mistério e a sedução, encontramos afetos queer que revisitam não só o barroco, mas o neobarroco em sua dimensão estética. O que as fotografias transmitem são transbordamentos performáticos que emulam nos corpos modos de recusar convenções sociais. Ao trabalhar com a sensibilidade, tocamos as imagens por meio da interação afetiva e percebemos como o corpo pode ser lido entre desejo e trauma.

Aim: To find suitable fertilizer and concentration for foliar application in cashew to improve fruit retention, nut yield and leaf nutrient content in South Chhattisgarh region. Methodology: An on-farm trial were conducted consecutively for three years from 2017-18 to 2019-20 to study the response of cashew trees to foliar application of major nutrients with respect to growth and yield attributes. The fertilizers selected for foliar application were NPK (19-19-19), Urea, NPK (13-0-45) and NPK (12-32-16) at 1 and 2 % along with non-sprayed trees as control. All the treatments were imposed in three replications under RBD design. The age of selected trees was 15 years. Results: Foliar spray of 2% Urea before the vegetative flush, after the vegetative flush and nut set stage gave significantly higher mean number of flowering panicles m-2, number of nuts at pea nut and marble stage, high fruit retention, more number of nuts per panicle, nut yield per tree, weight of 100 nuts and maximum leaf nutrient content at flowering and harvesting stages. Interpretation: Foliar application of fertilizers with primary nutrients lead to significant improvement in flowering, fruit set and leaf nutrient content, which may influence nut yield in cashew.

Conversion of waste polypropylene disposable cups into liquid fuels by thermal and catalytic pyrolysis using activated carbon
Authors: Aremanda Ramesh Babu , Singh R.K.
Published: May 2022

Polypropylene plastics are used extensively in packaging and food services for short usage, poses enormous disposal problem and contributing to over 45 % of globally generated plastic waste. Accordingly, the present work is focused on converting waste polypropylene(WPP) disposable cups in to liquid fuels by employing thermal and catalytic pyrolysis processes.  Characterization of WPP disposable cups were performed through proximate and ultimate analyses followed by TGA and found that 86% of its mass degrades in a temperature range of 430 – 603 oC. Effect of temperature in the range of 500 – 650 oC on liquid fuel production at a constant heating rate of 15 oC/min were noted in thermal pyrolysis, an optimum and stable liquid fraction of 76 % with a reaction time of 30 min was recorded at 500 oC. For studies on catalytic pyrolysis, activated carbon (AC) was applied from 470 to 530 oC at variable Feed to Catalyst (F/C) ratio of 1- 4, an optimum liquid yield of 74 % was obtained with a residence time of 35 min at 510 oC and F/C of 3:1. Thermo-physical properties of optimal liquid products were comparable with conventional fossil fuels. XRD and SEM analysis of AC catalyst were showed the presence of carbon at 24o and 42o of 2θ-angle with an apparel pore size of 2 µm.

Each motor vehicle produces a variety of noise. For areas which directly intersects the highway this noise has a considerable impact. The volume of motorcycles and private as well as public vehicles all have a significant effect on noise. From all analytical calculations, the largest equation was obtained one the second day of research on the second point of Sound Level Meter 2 (SLM2). The calculation is that y = 0,0158x – 1,0176. This equation indicates that if there is no decrease in the volume of the motorcycle, the noise level on the SLM2 is 65.21 dBA. If there is an increase or decrease in the volume of a motorcycle, it will have a significant effect on noise. The second largest equation was obtained on the second day of the research at the third point from the Sound Level Meter 3 (SLM3) and the calculation of the equation is y = 0,01 – 6,074. The purpose of the above equation is that if there is an increase in the volume of a motorcycle, the noise on the SLM3 is 60.840 dBA. According to the findings, there was a reduction in the number of motorcycles during the Covid-19 pandemic, because schools were closed and students did not attend school.

The purpose of this study is to evaluate Corporate Social Responsibility (CSR) programs for local communities around mining companies in Kalimantan, Indonesia, based on environmental, economic, and social perspectives. We create evaluation criteria consisting of; six on the environmental perspective, three on the economic perspective, and two on the social perspective. CSR reports are collected from the company website. Each company was given a score based on whether these evaluation criteria were present (1) or absent (0). The evaluation scores of the CSR mining companies programs’ in Kalimantan, Indonesia are high in considering cleaner production, waste reduction, material flow management, and recycling, committed to managing energy and water, developing infrastructures surrounding mining companies, has good corporate ethics, and encourages employees to volunteer for social causes and provides incentives for these activities; medium in committed to following all applicable laws and policies concerning environmental standards and policies, committed to conserving biodiversity, committed to managing sound and vibration from mining activities as well as protecting the air quality around the mining area, and enhancing self-employment options for local communities; low in taking long-term factors into accounts, such as global climate change and other environmental threats, and providing jobs opportunities for local communities. From the evaluations above, access to information, public participation, and transparency in discussing areas of corporate-community issues are all things that mining companies must improve. If there is a lack of congruence between aim, activity, and effect, civil society organizations should frequently criticize mining companies' CSR operations.
Analysis on strategic and environmental issues of remanufacturing in India
Authors: Sinha Ajay Kumar
Published: May 2022

Environmental awareness among masses has created tremendous pressure on government and corporates to preserve our natural resources. Globally, many companies have successfully initiated product recovery operations in their business plans. Remanufacturing is one of the highly profitable and sustainable product recovery options. Many Western countries successfully adopted remanufacturing as an alternate source of revenue generation model. But in India, it is still in nascent stage. In this research, we tried to identify the critical factors in the area of “Strategy & Environment” for the viability of remanufacturing business in India. For this, a questionnaire survey was conducted among Indian manufacturing companies and their responses were analyzed. The sample size of the study consists of 72 responses. Afterwards, the identified factors were ranked based on their criticality in initiating remanufacturing activity. The findings may help Indian government and manufacturing firms to frame proper strategy related to environmental aspect of remanufacturing operations in India.
