Bariatric surgery in patients with obesity is generally considered to reduce cancer risk in patients with obesity. However, for colorectal cancer some studies report an increased risk with bariatric surgery, whereas others report a decreased risk. These conflicting results demonstrate the need of more long-term studies analyzing the effect of bariatric surgery on colorectal cancer risk. Therefore, data from the Swedish Obese Subjects (SOS) study, ClinicalTrials.gov identifier: NCT01479452, was used to examine the impact of bariatric surgery on long-term incidence of colorectal cancer. The SOS study includes 2007 patients who underwent bariatric surgery and 2040 contemporaneously matched controls who received conventional obesity treatment. Patients in the surgery group underwent gastric bypass (n = 266), banding (n = 376) or vertical banded gastroplasty (n = 1365). Information on colorectal cancer events was obtained from the Swedish National Cancer Registry. Median follow-up was 22.2 years (inter-quartile range 18.3–25.2). During follow up there were 58 colorectal cancer events in the surgery group and 67 colorectal cancer events in the matched control group with a hazard ratio (HR) of 0.79 (95% CI:0.55–1.12; p = 0.183). After adjusting for age, body mass index, alcohol intake, smoking status, and diabetes, the adjusted HR was 0.89 (95% CI:0.62–1.29; p = 0.551). When analyzing rectal cancer events separately- 19 events in the surgery group and 31 events in the control group-a decreased risk of rectal cancer with surgery was observed (HR = 0.56; 95% CI:0.32–0.99; p = 0.045, adjusted HR = 0.61 (95% CI:0.34–1.10; p = 0.099), while the risk of colon cancer was unchanged. To conclude- in this long-term, prospective study, bariatric surgery was not associated with altered colorectal cancer risk.

Introduction

HIV testing is an important strategy for controlling and ultimately ending the global pandemic. Oral rapid HIV testing (ORHT) is an evidence-based strategy and the evidence-based shows is favored over traditional blood tests in many key populations. The dental setting has been found to be a trusted, convenient, and yet untapped venue to conduct ORHT. This study assessed the HIV testing behaviors and willingness to receive ORHT among dental patients in Xi’an, China.

Methods

A cross-sectional survey of dental patients from Xi’an was conducted from August to September 2017. Dental patients were recruited using a stratified cluster sampling. A 44-item survey was used to measure HIV/AIDS knowledge, HIV testing behaviors, and willingness to receive ORHT.

Results

Nine hundred and nine dental patients completed the survey with a mean HIV/AIDS knowledge score of 10.7/15 (SD 2.8). Eighty-four participants (9.2%) had previously received an HIV test. Participants would have a high rate of HIV testing if they had higher monthly income (OR = 1.982, 95% CI: 1.251–3.140) and a higher HIV/AIDS knowledge score (OR = 1.137, 95% CI: 1.032–1.252). Five hundred and eighty-two participants (64.0%) were willing to receive ORHT before a dental treatment, 198 (21.8%) were not sure, and 129 (14.2%) were unwilling. Logistic regression showed that age (OR = 0.970, 95% CI: 0.959–0.982), HIV/AIDS knowledge score (OR = 1.087, 95% CI: 1.031–1.145), previous HIV test (OR = 2.057, 95% CI: 1.136–3.723), having advanced HIV testing knowledge (OR = 1.570, 95% CI: 1.158–2.128), and having advanced ORHT knowledge (OR = 2.074, 95%: CI 1.469–2.928) were the factors affecting the willingness to receive ORHT.

Conclusions

The majority of dental patients had not previously received an HIV test, although many were receptive to being tested in the dental setting. The dental setting as a venue to screen people for HIV needs further exploration, particularly because many people do not associate dentistry with chairside screenings. Increasing awareness of ORHT and reducing testing price can further improve the patient’s willingness to receive ORHT.

Patients undergoing complex pediatric cardiac surgery in early infancy are at risk of postoperative secondary end-organ dysfunction. The aim of this study was to determine specific risk factors promoting the development of peri- and postoperative hepatopathy after surgery for congenital heart disease. In this retrospective study, we identified 20 consecutive patients operated between 2011 and 2019 from our institutional cohort who developed significant postsurgical hepatic dysfunction. These patients were compared to a control group of 30 patients with comparable initial cardiac conditions and STS-EACTS risk score. Patients who developed hepatopathy in the intensive care unit have chronic cholestasis and decreased liver synthesis. The impact of postoperative hepatopathy on morbidity was marked. In six patients (30%), liver transplantation was executed as ultima ratio, and two (10%) were listed for liver transplantation. The overall mortality related to postoperative hepatopathy is high: We found nine patients (45%) having severe hepatopathy and mostly multiple organ dysfunction who died in the postoperative course. According to risk analysis, postoperative right and left heart dysfunction in combination with a postoperative anatomical residuum needing a re-operation or re-intervention in the postoperative period is associated with a high risk for the development of cardiac hepatopathy. Furthermore, postoperative complications (pleural effusion, heart rhythm disorders, etc.), postoperative infections, and the need for parenteral nutrition also raise the risk for cardiac hepatopathy. Further investigations are needed to reduce hepatic complications and improve the general prognosis of such complex patients.
Efficiency and Outcome of Healing Practices Performed by Spirit Dancers in Healing Mental Illness – A Patient’s Perspective
Authors: Amin Prakasha , A.K Mohan
Published: March 2021

BACKGROUND In many rural communities, the cause of mental illness is attributed to black magic, spirit possession of past sin and the coastal region of Karnataka is not exempted from it. The natives of this region ascribe the cause of mental illness to the spirit or demigod, and they seek the help of traditional healers such as spirit dancers for the recovery. This help-seeking behaviour of the people results in delay in seeking psychiatry care and affects the recovery of the person with mental health problems. Therefore, this study explores the opinion of clients undergone traditional healing for mental health problems and the results of the study could contribute to planning an appropriate health promotion activity to promote community mental health. METHODS The present study was explorative, undertaken in the Udupi district of Karnataka state, which explores the views of the respondents about the cause of mental health problem and the outcome of traditional healing for their problems. Altogether 200 clients visiting traditional healers for mental health care were interviewed based on the snowball sampling technique and the interview schedule was used as a tool to gather the data. RESULTS Of the 200 respondents interviewed, 27.5 percent were adults (31 to 40 years), while 43.1 percent were unemployed. Black magic was found to be the major cause for mental health problems among 25.5 percent of the respondents; whereas, 26 percent of the respondents felt recovered completely after undergoing traditional healing for mental health problems. CONCLUSIONS The recognition of mental health problems is very much essential for people with mental health problems to seek professional help. This could help mental health professionals to diagnose illness at the very beginning and provide better mental health care. However, the explanatory model of the patients needs to be taken into consideration while providing modern medical care.

Published: March 2021

BACKGROUND Pancreatic lesions range from inflammation to malignancy and are associated with high morbidity and mortality. Imaging pancreatic lesion is challenging as pancreas is located retroperitoneally and with close proximity to bowel and major blood vessels. Abdominal pain, vomiting, and nausea are commonly reported symptoms. They are associated with high morbidity. Multi detector computed tomography (MDCT) is the modality of choice for detecting pancreatic pathology. It is highly sensitive in detecting necrosis, pancreatitis, peripancreatic fluid collections, calcification, neoplasm, pancreatic enlargement, atrophy and cystic lesions of pancreas. Computed tomography (CT) scan has made it possible to identify and detect various benign and malignant pancreatic lesions. METHODS A prospective observational study of 180 patients with complaints suggestive of pancreatic disease was done based on clinical, laboratory and ultrasonography in the Department of Radiodiagnosis, Acharya Vinoba Bhave Rural Hospital, Datta Meghe Institute of Medical Sciences, Sawangi (Meghe). Siemens Somatom 16 slice CT scan machine was used. All 180 patients underwent plain and contrast enhanced CT scan. RESULTS Out of 180 study participants 105 (58.33 %) were with acute pancreatitis followed by 43 (23.89 %) with chronic pancreatitis, 21 (11.67 %) with acute exacerbation of chronic pancreatitis, 10 (5.56 %) participants with carcinoma pancreas and 1 (0.56 %) participant with pancreatic injury participated in the study. CONCLUSIONS Contrast enhanced computed tomography (CECT) is an excellent diagnostic modality to stage severity of inflammatory process, staging of neoplastic lesions and traumatic injury. It is most accurate and affordable non-invasive imaging modality for the evaluation of pancreatic lesions. It is a standard investigation to identify and quantify distribution of various pancreatic lesions and also evaluates activeness and progression of disease. Thus, it helps in accurate diagnosis and characterization of lesion and in proper treatment of patients. KEY WORDS Pancreas, Imaging, Computed Tomography

Published: March 2021

Medical management of radiation emergencies will require quick and reliable biodosimetric tools for assessment of absorbed dose. Dicentric chromosomal assay (Gold standard) has a limitation of being time intensive, requires specialised human skill and cannot be used for triage and mass screening. Dose assessments of suspected individuals are critical for the medical management of radiation emergencies. For effectively utilizing the available resources, there is an urgent need for developing triage biodosimetry tools for determining the exposure status of suspected individuals. High-throughput methods, utilising the novel “omics” science approaches are emerging as new technologies and gene expression-based biodosimetry is considered a promising technique for radiation dose assessment. Gene expression signatures of radiation have demonstrated the potential for triage biodosimetry. It is a minimally invasive, rapid and reliable approach that has the ability to be a robust field-deployable point-of-care high throughput technique. In addition gene expression based biodosimetry can be useful for long-term epidemiological assessment, clinical radiation oncology and radiodiagnosis.

Authors: Lourembam Dharmeshwari , Ete Leeyir
Published: March 2021

Modernisation of a nation, besides yieldingpositive outcomes, has also ushered in various negative constructs, one of the chief being the growth of spiritual threats. Spiritual well-being provides reasons for one’s existence,increases resilience and provides stability for an overall development of a healthy, secure nation. Therefore, risk to spiritual well-being has immense negative impact on the mental state of an individual, especially, the youth. The ingrained spirituality in the culture of Arunachal Pradesh working as a protective buffer, and the status of the students being an educated class give the tribal students of the state, a powerful role in shaping the future security and progress of the society. Considering this implication, the present paper tries to explore how spiritual well-being and its two dimensions, namely, religious and existential well-being, are related to satisfaction with life, positive affect, negative affect and resilience. The Spiritual Well-being Scale, The Satisfaction With Life Scale, Positive Affect Negative Affect Schedule and The Brief Resilience Scale were administered to 100 university students, age ranging from 22-28 years. Results revealed that spiritual well-being was positively related to higher satisfaction with life, positive affect and resilience and negatively with negative affect. Implications of the studyhave also been discussed.
Reflections on Sustaining Morale and Combat Motivation in Soldiers
Authors: Maheshwari Nidhi , Sharma Rachana , Kumar V. Vineeth
Published: March 2021

Military morale and motivation formulate the signature strength of a fighting force. However, sustenance of these faculties is a bigger challenge than generating them. The exponential development in the neo-cortex and emerging social structure has made human beings hardcore individualistic. The sense of ‘self’ has become much stronger than the sense of the whole. This results in the recurrent violation of collective identity, as evidenced by the rise in numbers of misconduct behaviors, mutinies, estranged leader-led relations, desertion, fragging, and suicides. Utilizing the lessons from various ecological systems and derived scientific principles, the present paper takes note of significant researches in the area to arrive at a reflective model of Morale and Combat Motivation in soldiers. Firstly, it attempts to understand ‘why and why not the soldiers shall fight’ and subsequently give suggestive guidelines to ‘how they will continue to fight’ with particular reference to the Indian military setup. The model can be utilised by military leaders and policymakers alike who are entrusted with the herculean task of upkeeping battle-mind state of soldiers in military organisations.
The effect of organization-public relations on sports fan loyalty
Authors: Çelebi Engin
Published: March 2021

Public relations practitioners are obliged to facilitate the dialogue between the organization and public. Dialogue plays an important role in sports clubs because the gathering of people from different perspectives and opinions formed by fan groups for a common goal is based on dialogue and tolerance. Public relations theories have important applications for sports clubs to improve their relations with their fan groups. Linking the relational results to the public relations process can contribute to a better understanding of the mission and vision of sports clubs by fan groups and to measure their support. Within the scope of the research, it was aimed to determine the effective strategies necessary for sports clubs to increase the number of fans and their support. In this context, as a result of the research conducted on 176 sports fans, it has been found out that public relations strategies (control mutuality, trust, satisfaction) are the pioneers of fans loyalty. Also, public relations perceptions were found to be a determining factor in supporting behaviors towards sports clubs. Sports fans define their relationship with sports organizations as a communal relationship based on one-sided support rather than an exchange based on mutual benefits. As a result of the research, some suggestions are made for sports clubs to improve the quality of their relations with their supporters’ groups.
Is Simvastatin Associated with Oral Lichenoid Drug Reaction?
Authors:   Oral Medicine Department, Faculty of Dentistry, Chulalongkorn University, Bangkok 10330, Thailand, Thongprasom Kobkan
Published: March 2021

Currently, various drugs have been found to induce many oral lesions. Some medications used to treat systemic diseases can affect the oral mucosa and induce lesions known as oral lichenoid drug reaction (OLDR). The diagnosis is made when the oral lesion errupted after the patient took a specific medication. However, diagnosis is challenging when a patient takes multiple medications and the onset of the eruption is unclear. OLDRs commonly cause severe pain in the oral cavity and affect the quality of life. Statins are widely used by patients with cardiovascular disease (CVD) to lower blood cholesterol levels, decreasing the risk of heart attack or stroke. This review will focus the side effects of a hypolipidemic drug group (statins) in the oral cavity. From previous experience, simvastatin may be related to severe oral ulcerations, dysplasia, and carcinoma in situ in the oral mucosa. Moreover, simvastatin combined with amlodipine can induce more severe oral lesions that are very difficult to treat. Therefore, the beneficial effect of these drugs and their side effects should be considered carefully, because simvastatin significantly affects oral and general health.

Authors: Yuliani Krista , Ardianto Hendra Try
Published: March 2021

Artikel ini bertujuan untuk memberi gambaran bagaimana seorang kandidat dari kelompok minoritas, bisa memenangkan pemilu, padahal lawan yang dihadapinya adalah calon petahana (imcumbent). Guna memenuhi tujuan itu, artikel ini berangkat dari penelitian studi kasus tentang kemenangan Budhi Sarwono sebagai kandidat Tionghoa (Muslim) saat Pilkada 2017 silam. Dalam penggalian data, penulis melakukan wawancara mendalam terhadap kandidat, para petinggi partai di tingkat lokal, serta warga yang mengetahui dinamika politik saat itu. Temuannya adalah keberhasilan Budhi Sarwono dalam Pilkada 2017 adalah hasil dari equivalensi antara habitus warga yang marah karena infrastruktur jalan di kawasan dataran tinggi banyak yang rusak; kemudian bertemu dengan ranah politik vis-a-vis petahana; dan injeksi modal kandidat  (modal sosial-kultural, ekonomi, politik) yang dikapitalisasi untuk meraih suara warga. Kesimpulannya, strategi politik akan berjalan efektif jika mempertimbangkan bagaimana komposisi ranah, habitus, dan modal kandidat agar bisa saling terjahit secara koheren.

Aktivis Dakwah di Tengah Percaturan Politik Kampus: Dinamika Gerakan Keislaman di Universitas Diponegoro
Authors: Ardianto Hendra Try
Published: March 2021

Artikel ini menyoroti bagaimana dinamika gerakan aktivis dakwah di tengah percaturan politik kampus. Lokus dari percaturan politik ini adalah seputar perebutan posisi ketua di organisasi intrakampus, baik organisasi kerohanian maupun Badan Eksekutif Mahasiswa (BEM). Dengan mengandalkan pada metode kualitatif deskriptif, penelitian ini menggali data dari aktor-aktor yang terlibat dalam kontestasi politik kampus, seperti aktivis dakwah, aktivis mahasiswa sekuler, dan pihak representasi perguruan tinggi. Temuannya menunjukkan bahwa kuatnya dominasi KAMMI sebagai representasi kelompok Tarbiyah dalam menduduki jabatan-jabatan strategis di organisasi intrakampus bukan terjadi karena kelompok keislaman lain yang meredup dan meninggalkan aktivitas dakwahnya. Sebaliknya, kelompok aktivis dakwah non-Tarbiyah juga terbukti aktif dalam berbagai aktivitas dakwah, mulai dari kaderisasi, forum pengajian, bahkan diskusi seputar politik kontemporer di kampus. Kesimpulannya, posisi dominasi status quo yang disandang KAMMI bukan sekadar karena mereka aktif meramaikan masjid dan mengelola organisasi kerohanian, namun juga karena politik eksklusi yang mereka lakukan kepada kelompok lain, baik eksklusi secara kultural maupun struktural.

Study of load-bearing timber-wall elements using experimental testing and mathematical modelling
Authors: Premrov M. , Ber B. , Kozem Šilih E.
Published: March 2021

Combining timber and glass in the wall elements of the building envelope with the proper orientation of such transparent façade elements enables the utilization of solar energy for heating and internal illumination of the building. However, the asymmetrical layout of timber-glass wall elements in such buildings can result in problems with the horizontal stability of the structure, so their participation to load-bearing capacity of the structure is usually neglected. The study deals with solutions for such elements as horizontal load-bearing members with proper connection details. First, specifically developed timber-glass wall elements were experimentally tested under monotonic and cyclic horizontal point load, and further in combination with classical timber-framed wall elements implemented into special single and two-storey box-house models, which were further experimentally tested on the shaking table. In the second part as the main goal of the study, a quite simple mathematical model of the box-house prototypes is developed using a fictive diagonal element for simulating the racking stiffness of the bracing timber-glass wall element. The calculated results for the 1st vibration period are compared with the previously measured experimental results to prove an accuracy of the developed model. Finally, a linear time-history calculation is done as a sample presentation of the developed mathematical model using Landers acceleration spectrum. The developed mathematical model enables a simple and effective seismic response calculation of timber buildings considering the developed timber-glass wall elements as load-bearing bracing elements against horizontal load actions. The model can also be recommended for using in further parametric numerical academic studies analysing the influence of various parameters.
The implications of product modularisation on the development process, supplier integration and supply chain design in collaborative product development
Authors: Koppenhagen F. , Held T.
Published: March 2021

Generating economies of scale is one of the most desirable goals when developing modular product systems. Since complex products are commonly developed in collaboration between an Original Equipment Manufacturer (OEM) and its suppliers, pursuing this goal inherently establishes interdependencies between the development process, supplier integration and supply chain design. To fully reap the benefits of modular product systems requires a comprehensive approach that encompasses these fields and addresses the inter-dependencies between them via a coherent collaboration between development and purchasing. This is the main focus of this work. In this paper, we first describe how the product development process has to be restructured for the concerted development of modules and overall products within the scope of a modular product system. Secondly, we propose a new collaboration model between the OEM and its suppliers, since OEMs need to collaborate directly with suppliers of lower levels of the value chain in order to facilitate the standardisation of components and modules across different products. Finally, we delineate an awarding process for both development services and production volumes for series supply that resolves the conflicting priorities of economies of scale and avoiding over-dependence on single suppliers. The process models described in this paper have been conceived based on systems engineering principles and have been successfully tested and further refined throughout several industrial projects carried out with two automotive manufacturers. The resulting approach will be demonstrated using a generic example taken from the automotive industry.

Published: March 2021

Improving customer satisfaction and shortening the manufacturing cycle have become common concerns of current manufacturers. This paper presents a multi-objective location model considering the maximization of collaborative manufacturing capabilities and service benefits. This method first uses the two dimensions of customer share and market consumption to segment customers, and identify the weight of various customer groups. Secondly, the space vector model (VSM) is used to calculate the matching between manufacturing capabilities and manufacturing requirements. Then build a multi-objective location model based on the two goals of collaborative manufacturing capabilities and service benefits. Finally, the model was tested with simulation data, which proved the validity and feasibility of the model. According to the simulation results, managers can accurately select the optimal manufacturing base from multiple candidate manufacturing bases with regard to less costs, shorter lead times, better manufacturing capabilities, better service benefits. In this paper, Fuzzy theory, Logit model and VSM are combined to salve the problem of manufacturing base location. Considering resources and service benefits of each manufacturing base, it is helpful to optimize the location of enterprises. From the academic and practical points, this study provides a new perspective for the location problem.
Critical Theory and the Critique of Capitalism: An Immanent Critique of Nancy Fraser's “Systematic” “Crisis-Critique” of Capitalism as an “Institutionalized Social Order”
Authors: O'Kane Chris
Published: March 2021

The predominant approach to contemporary critical theory lacks a critical theory of capitalist society. Nancy Fraser has endeavored to provide such a critical theory in her “systematic” “crisis–critique” of capitalism as an “institutionalized social order.” Yet Fraser's “systematic” theory is not systematic, but fragmentary and internally inconsistent. The Marxian premises of Fraser's theory are at odds with its ensuing Habermasian notions of capitalism, contradiction, crises, and emancipation, and her theory consequently lacks a robust explication of these dynamics. This raises the alternative possibility of developing a contemporary critical theory of the crisis–ridden reproduction of the negative totality of capitalist society that brings Adorno and Horkheimer's critical theory together with the subterranean strand of contemporary critical theory: the New Reading of the critique of political economy as a critical social theory.
The onset of magnetic nanofluid convection because of selective absorption of radiation
Authors: Mahajan Amit , Sharma Mahesh Kumar
Published: March 2021

This article reports a linear stability analysis of the onset of convection stimulated by selective absorption of radiation in a horizontal layer of magnetic nanofluid (MNF) under the impact of an external magnetic field. The Chebyshev pseudospectral method is utilized to obtain the numerical solution for water-based magnetic nanofluids (MNFs). The confining boundaries of the magnetic nanofluid layer are considered to be rigid–rigid, rigid–free, and free–free. The results are derived for two different conditions, viz., when the system is heated from the below and when the system is heated from the above. It is observed that an increase in the value of the Langevin parameter , diffusivity ratio  and a decrease in the value of nanofluid Lewis number , the parameter  which represents the impact of selective absorption of radiation and modified diffusivity ratio  delays the onset of MNF convection for both the two configurations. Moreover, as the value of concentration Rayleigh number  increases, the convection commences easily when the system is heated from the below, whereas the onset of MNF convection gets delayed as the system is heated from the above.

Bu doğrultuda çalışmada, gelişmiş ülkeleri temsilen İsveç ve gelişmekte olan ülkeleri temsilen Pakistan için karbon emisyonları, enerji tüketimi, gelir ve dış ticaret arasındaki dinamik nedensel ilişkileri 1971-2020 döneminde ARDL Sınır Testi (Autoregressive-Distributed Lag) ile incelenmiştir. Analiz sonucunda, İsveç’teki CO2 emisyonunun, uzun vadede ticari enerji kullanımı ve bir önceki dönemin CO2 emisyonu ve bir önceki döneme ait ticari enerji kullanımıyla; kısa vadede sadece ticari enerji kullanımıyla ilişkili olduğu elde edilmiştir. Pakistan’daki CO2 emisyonunun, uzun vadede, ticari enerji kullanımı, GSYH ve bir önceki döneme ait CO2 emisyonuyla; kısa vadede ticari enerji kullanımından ve GSYH ile ilişkili olduğu elde edilmiştir. Ülkelerin gelişmişlik düzeylerin ve Karbon risklerinden bağımsız olarak çevre kirliliğini açıklamada en önemli değişkenin ticari enerji tüketimi olduğu elde edilmiştir.

İş piyasasına giriş öncesinde, bireylerin kendilerini tanıması, niteliklerini değerlendirmesi, çevresindeki fırsatların farkına varması ve bunlardan yararlanarak kariyer hedeflerini belirlemesi son derece önem arz etmektedir. Fakat kariyer planlama sürecinde yaşanan olumsuz olaylar ve krizler bu süreci önemli derecede etkilemektedir. Yaşanan (Covid-19) pandemi süreci, üniversite öğrencilerinin kariyer planlaması açısından önemli bir kriz durumu yaratmıştır. Bu araştırmanın amacı, pandemi sürecinde üniversite öğrencilerinin psikolojik dayanıklılık ve umutsuzluk düzeylerinin kariyer geleceği algılarını ne şekilde etkilediğinin belirlenmesidir. Bu amaçla, üniversite öğrencileri arasından kolayda örnekleme seçilen 410 kişiden çevrimiçi bir anket aracılığıyla veriler toplanmıştır. Araştırmada kullanılan ölçeklerin yapı geçerliliği ve güvenilirliğini değerlendirmek için doğrulayıcı faktör analizi yapılmıştır. Veriler yapısal eşitlik modelleri kullanılarak analiz edilmiş ve analizler sonucunda psikolojik dayanıklılığın kariyer gelecek algısını hem doğrudan, hem de (umutsuzluk üzerinden) dolaylı olarak pozitif yönde etkilediği belirlenmiştir. Cevaplayıcıların umutlu olma düzeylerinin bir yandan kariyer gelecek algısını pozitif yönde etkilerken, diğer yandan da psikolojik dayanıklılık ile kariyer geleceği algısı arasındaki ilişkide aracı rol oynadığı belirlenmiştir. Bu bulgular çerçevesinde teorik ve uygulamaya dönük bazı öneriler sunulmuştur.

Androgen-induced epigenetic modulations in the ovary
Authors: Salinas Irving , Sinha Niharika , Sen Aritro
Published: March 2021

In recent years, androgens have emerged as critical regulators of female reproduction and women’s health in general. While high levels of androgens in women are associated with polycystic ovary syndrome (PCOS), recent evidence suggests that a certain amount of direct androgen action through androgen receptor is also essential for normal ovarian function. Moreover, prenatal androgen exposure has been reported to cause developmental reprogramming of the fetus that manifests into adult pathologies, supporting the Developmental Origins of Health and Disease (DOHaD) hypothesis. Therefore, it has become imperative to understand the underlying mechanism of androgen actions and its downstream effects under normal and pathophysiological conditions. Over the years, there has been a lot of studies on androgen receptor function as a transcriptional regulator in the nucleus as well as androgen-induced rapid extra-nuclear signaling. Conversely, new evidence suggests that androgen actions may also be mediated through epigenetic modulation involving both the nuclear and extra-nuclear androgen signaling. This review focuses on androgen-induced epigenetic modifications in female reproduction, specifically in the ovary, and discusses emerging concepts, latest perceptions, and highlight the areas that need further investigation.
A simple graphic method to assess correlation
Authors: Winkler Othmar W
Published: March 2021

This study explores the correlation between two variables and to demonstrate a simple graphic method to assess their degree of correlation. Following the lead of early English biometricians, it has been tacitly assumed that the studied variables develop in the same direction: when variable A’s measurements are higher from one object to another, the measurements of variable B, also are higher. The customary measure of co-relation relies on a least squares fitted trend line, then assuming that the trend is more real than, and has priority over the individually recorded data. The situation changes when measurements of variables develop in opposite directions: The very first data set I used to perform a correlation analysis was a study of student grades achieved and the percentage of their having missed classes: the more a student was absent from class, the lower were his achieved grades. In that situation the accepted model of correlation analysis – the mathematically fitted straight line and the squared distance of each student’s record from that line - was not appropriate. The usual correlation coefficient contradicted visual evidence of those data because the model underlying that situation treats the individual data as having more reality value than the general trend, but not as deviations or errors. The visual appearance, the graph of that situation, resembles a rectangular triangle, formed by the horizontal and vertical axis as its catheters, and the hypotenuse formed by a line through and representing the highest data points. This image justifies the expression “Triangular correlation”.

Objective: Violence Against Women (sociodemographic variables of the victim, type of violence and characteristics of the aggressor), reported to the public health surveillance system (SIVIGILA) in the department of Huila, during the period 2013-2018. Methodology: an observational, descriptive study was carried out, taking the data collected through the XLS files for notification of the "Gender Violence" event, reported to SIVIGILA. During the period under investigation. Results: Non-sexual violence is the form of violence to which women are most exposed, with 76.81% of cases, being more than 3 times greater than the form of sexual violence. Women are more likely to endure physical violence, 8,432 cases and psychological violence, 4,006 cases. In 80.26% of cases of gender violence against women, the aggressor is a man, and it is probable that the victim has some kind of family relationship with the aggressor; possibly being his partner, 7,137 cases or ex-partner, 3,264 cases. Conclusion: in the department of Huila, women between 10 to 39 years old are more likely to suffer physical, sexual and psychological violence; men being the main aggressors and in most cases the sentimental partners of the victims. The most used mechanisms to inflict damage by the aggressors are short-blunt and sharp objects.

Development of the antimicrobial activity of cotton fabric using chitosan, N-(2-Hydroxy) propyl-3- trimethyl-ammonium chitosan chloride (HTACC), and N-methylol-acrylamide-N-(2-hydroxy) propyl-3-trimethyl-ammonium chitosan chloride (NMA-HTACC) was investigated. Moisture absorbency is an important property of cotton fabric due to which bacteria can easily affect the cotton fabric and lowers the quality of it. Chitosan, HTACC, and NMA-HTACC were applied on cotton fabric by exhaustion method and observed antibacterial activity against Escherichia coli and Staphylococcus aureus. Among the finished fabrics, NMA-HTCC treated cotton fabric showed over 93% of bacterial reduction against E. coli and over 97% of bacterial reduction against S. aureus even after 30 home launderings. This is due to the strong attachment ability of NMA-HTACC to cotton fabric and better solubility in aqueous solution and the presence of positive charge of the nitrogen atom in its structure in all conditions. For this reason, NMA-HTACC can be applied to develop cotton fabric as anti-bacterially active which makes it suitable for medical purposes by minimizing the chances of growth and multiplication of bacteria.

Consumers, manufacturers, and retailers worldwide are becoming conscious about high quality products at minimum cost. But plenty of apparels are becoming waste which increases the cost of production. As resources are decreasing but increasing costs of the products. Effective apparel waste management is needed to ensure the profit. Reducing such waste can be profitable options for the manufacturers as well as the buyers. Considering this matter, a project work is done in a ready-made garment manufacturing industry to improve the quality of the products through using a traffic light system. A traffic light system was implemented to minimize the defect rates of production. The study shows that the average defect rates were dropped from 4.13 to 1.25 pieces of a line for daily eight hours of production. By implementing this system, the defect rates are minimized and the monthly production is also increased and it clearly depicts that the monthly capacity before implementing the traffic light system was equivalent but the defective production was more whereas, after implementation, the defective production was negligible.
