Open to interpretation? Inconsistent reporting of lifetime nonsuicidal self-injury across two common assessments
Authors: Robinson Kealagh , Wilson Marc
Published: September 2020

© 2020 american psychological association. Nonsuicidal self-injury (NSSI) is typically assessed using either single-item questionnaires or checklists of common behaviors, but preliminary research suggests that checklists produce higher lifetime prevalence rates. In 2 preregistered studies (combined n = 1,364), we tested whether memory cueing afforded by behavioral checklists accounts for this discrepancy. Participants reported their lifetime NSSI history using both a single-item and a checklist, with presentation order randomized across participants. Nearly a third of participants reported inconsistent NSSI histories on the 2 assessments, with participants 1.57 times more likely to report an NSSI history on a checklist than on a single-item. Counter to the memory account, this discrepancy was evident even when participants completed the checklist first, suggesting that the increased prevalence estimates captured by checklists are unlikely to simply reflect memory facilitation. Across the 2 samples, 12.5% of participants would have been incorrectly screened out in 2-step assessments; these participants were more likely to have engaged in NSSI historically, less likely to self-injure by cutting, and (in Study 2 only) were more likely to be men. These studies suggest that the inconsistencies across 2 of the most common NSSI assessments arise because people dissimilar to the lay conceptualization of self-injury are less likely to endorse a single-item, even when they have affirmed engaging in self-injury behaviors on a checklist. We argue that single-item and checklist assessments capture different aspects of NSSI, such that future research should distinguish between behaviorally identified NSSI assessed with behavioral checklists and self-identified NSSI assessed with single-item assessments.
Geçici koruma altına alınan suriyelilerde göç, kültürleşme/kültürel uyum ve din ilişkisi: Kayseri örneği
Authors: TANRIVERDİ Abdullah , ULU Mustafa
Published: September 2020

Bu çalışmada Türkiye’ye zorunlu göç eden Suriyelilerde kültürel uyum ve din ilişkisi nitel araştırma yöntemi ile ele alınmaktadır. Çalışmada, öncelikle mülteci, sığınmacı ve geçici koruma statüleri açıklanmaya çalışılmıştır. Sonrasında ise çalışmanın amacına ve araştırma sorularına uygun şekilde din ile dini inanış ve yaşantıların göç ve kültürel uyum üzerinde nasıl bir etkisinin olduğunu değerlendirilmeye çalışılmıştır. Buna göre Suriyeliler, Avrupa’ya gitmek konusunda ikilem içerisindedirler. Batılı devletlerin ekonomik refahından etkilenmelerine rağmen kültürel, sosyal ve dini farklılıklar isteksizlik uyandırmaktadır. Ancak ortak birçok özelliğe rağmen yaygın ülke milliyetçiliği ya da asabiyet sebebiyle Arap ülkelerine dair görüşleri oldukça olumsuzdur. Suriyelilerin Türkiye’ye göç etmelerinin nedenleri arasında daha önce göç edenlerin etkin bir rol üstlenmesi, coğrafi yakınlık ve sığınmacılara karşı daha olumlu tavır yer almaktadır. Göç ve uyum süreçlerinde karşılaşılan zorluklarla mücadelede dini inanç, bir tür sığınak olarak görülmektedirler. Ancak Türkiye’deki toplumsal yapının etkisi sebebiyle bazılarında bağlılık ve ibadet etme sıklığının azaldığı da anlaşılmaktadır. Türklere dair algılarda Türklerin yalanı sevmedikleri, sünnete Araplardan daha fazla önem verdikleri, dini değerler konusunda çok titiz oldukları düşünülmekte ise de kadın-erkek ilişkilerinin İslam’a uygun olmadığı, dindarların azınlıkta kaldığı, İslami emirler arasında farklı uygulama biçimlerinin olduğu vb. görüşlerin hakim olduğu görülmüştür. Psikolojik açıdan iç savaşın ve göç ettikten sonra karşılaştıkları ağır ekonomik ve sosyal durumların Suriyeliler üzerinde derin izler bıraktığı, dramatik ve travmatik bazı tecrübelerin psikolojilerini oldukça etkilediği ve bunlarla baş edebilmek için tıbbi desteğe ihtiyaç duydukları anlaşılmıştır. Sığınmacıların geleceğe yönelik duygu ve düşünceleri kapsamında ise; a. katılımcılardan bazıları Suriye’ye dönmek istemedikleri, b. Bazılarının dönmek istedikleri, c. bazılarının savaş bittiğinde her iki ülke ile de ilişkilerini sürdürmek istedikleri ve görülmektedir.

Authors: AYTEN Kenan , SONMEZ Mehmet
Published: September 2020

Günümüzde gelişen teknolojiler ve hızlı bilgi aktarımı nedeniyle kablosuz haberleşmede Radyo Frekansı (RF: Radio Frequency) bantları hızla dolmakta ve frekans bandının üst sınırlarına doğru ulaşmaktadır. Bu durum yeni alternatif iletişim teknolojilerine olan ilgiyi arttırmaktadır. Bu nedenle kısa mesafelerde RF üzerindeki veri trafiğini hafifletmek için Görünür Işık Haberleşmesi (VLC: Visible Light Communication) devreye girmektedir. VLC sistemlerinde modülatör ve demodülatör tasarımı hata performansı, bantgenişliği verimliliği, güç verimliliği gibi özellikleri etkilediğinden dolayı çok önemli konulardan birisidir. Bu nedenle yapılan çalışmada VLC sistemleri için kullanılan DPIM (Digital Pulse Interval Modulation: Dijital Aralıklı Darbe Modülasyonu) tekniğinin performans analizi gerçekleştirilmiştir. Analizler MATLAB ortamında gerçekleştirilmiştir. Yapılan çalışmada DPIM tekniğine hata düzeltme kodları entegre edilmiştir. Entegre edilen hata düzeltme kodlarının matematiksel alt yapısı oluşturularak, benzetim ortamında geleneksel sistem ile SER (Slot Error Ratio: Sembol Hata Oranı) ve PER (Packet Error Ratio: Paket Hata Oranı) karşılaştırılması yapılmıştır. Hata düzeltme kodları eklenmiş olan alıcı yapısının geleneksel DPIM alıcı yapısına göre daha iyi bir hata performansı sergilediği görülmüştür. Bu nedenle benzetim sonuçlarından hata düzeltme kodlarının geleneksel yapıya göre daha yüksek alıcı-verici arasındaki mesafeler için veri iletimini sağlanabildiği görülmektedir. Özellikle sabit eşik değeri uygulamasında hata düzeltme yapısının hata performansını oldukça yüksek bir şekilde geliştirdiği görülmektedir.

Authors: Kostina G. D. , Torgasheva A. V.
Published: September 2020

Creation of a project team is the first stage in the long sequence of all works which are related to the desired project. At this stage, a group of participants should be carefully chosen, based not only on their experience in the project area, but also on their compatibility and willingness to work together in a mutually helping way. In the paper, after a survey of related publications, project team types and characteristics are considered and arising problems are identified. These problems are related mainly to badly specified duties of team members, weak information links between them, fuzzy project goal and competition for dominance between members, It is found, that the project team formation can be viewed as a mathematically complex multi-criteria optimization task. A new method of team formation is proposed, which does not require deep mathematical background from the project manager. The method is based on the use of the competence technique. However, in contrast with the use of this technique in human resource management, the proposed method takes into account the important aspect of psychological compatibility of team members, which can appear to be the decisive factor in the project success. The method is presented as a simple algorithm which can be used by the project manager in the team formation.
NATA SANKIRTANA AND MANIPURI SOCIETY
Authors: Singh M.Thoiba
Published: September 2020

The Nata Sankirtana style of singing which was introduced during the reign of Rajarshi Bhagyachandra (1763-1798 A.D.). The great masters and scholars of that period composed and sang the padavali strictly after the Bhagavata tradition and other major Vaishnavite text and based the composition also on the traditional Ragas and Raginis of classical music tradition. Modern research has discovered a lot of regional overtones in the architecture of the particular Ragas and Raginis. The Manipuris call the Nata Sankirtana singing their own and it is clearly a form of collective prayer, a Mahayajna as they call it, lasting for about 5 hours at a stretch with a lot of rituals, movements and rhythmic pattern, strictly after the vaishnavite faith. Nata Sankirtana is a composite version of music, dance and tala; a Sangeet in the true sense of the term. It is also Drishya Kavya, a poem made visible. Nata Sankirtan is a very important aspect in the lives of the people in Manipur. It is because when our end is near, people listen to Hari-naam to relieve us from all the wrong doings that we have done before, so that we die peacefully. After death the family members would take the dead body for the last rites. In the shraddha ceremony, the Nat Sankirtana will start with raga. Before the invocation of the god and prayers start, Pinda- dan cannot be offered. After offering the Pindadan, the owner of the ceremony will have a bath and wear washed clothes. He will then come and offer his respects towards the end of the Sankirtan when Raga Bijay is being performed. The Shraddha ceremony comes to an end with the guardian of the Mandap sending the departed soul to beikuntha dham.  In case of any death in a house, Naam Sankirtana plays an important role. In the ten days of mourning or Dashahan, the ritual will start with Naam Sankirtana and other rituals like reading Shrimad Bhagavat Gita will follow. The particular person who mourns, known as the Gira thangba, will only offer Pindadan after the Sankirtana starts. Even in asti sanchai or the ritual of picking up the remains from the grave, Sankirtana is performed along with Parikrama around the Hari mandir. In this manner,for Meitei Vaishnavites living in the society today, Nat Sankirtana Mahayajna was become an indispensable event in the lives of the people since time immemorial. In short, Nata Sankirtana is the only highest karma for the Meitei society. This paper attempts to understand the important role of Nata Sankirtana in Manipuri society.

Authors: Chereshnev Valeriy , Poznyakovskiy Valeriy
Published: September 2020

The article considers the microbiota of modern people and its changes in the course of evolution under the influence of external and internal environment factors. The researchers explain the diversity loss and lack of beneficial microorganisms by the lack of carbohydrates available to the microflora (CAM) in the man diet, including dietary fiber fermented into short chain fatty acids (SCFA) - the main source of energy and intestinal microflora metabolism regulator. The authors demonstrated the intestinal microflora connection with other organs and systems of the human body, including the immune and nervous systems, and determined its significance in the occurrence and development of common diseases. Special attention is paid to the analysis of pro-, pre-, metabiotics and their metabolites, which have individual differences in the metabolic processes of a healthy and sick organism. The mechanisms and ways of implementing these functions depend on specific microorganism strains, that determines the prospects for creating and applying new biotechnological products with directed functional properties. A man noted antagonistic contradictions between own and produced strains. The article demonstrates that the microorganism genome is able to evolve in the struggle for survival, responding to changing nutritional conditions by delegating a huge number of genes to the human genome, indicating the need for nutrient-metabolic support of the microbiome. The issues of “aging” microbiota and the possibility of its support, as well as the transfer of beneficial bacteria from the donor to the recipient’s intestines, carrying out the transfer of positive physiological characteristics are interesting. The researchers discussed decoding process prospects of sequencing the genes that make up the human genome, the mechanisms of forming a personal microbiome for understanding the diseases pathogenesis and developing highly effective therapies. The most effective way to restore and preserve healthy microflora is a scientifically based diet with the additional inclusion of specialized products, the active principles of which are the producers of various bacteria.

Pollock (Theragra chalcogramma) remains one of the main fishing objects in the far Eastern region. The most popular product on both the domestic and international markets is fillet, when it is frozen it can be used to produce a wide range of finished products. The main technology for obtaining iced fillet consists of its production in a fixed or loose form. A man conducts the operation «fixed fillet» immediately after filleting fresh fish by irrigation or immersion in a cold 10 % solution of table salt. The research purpose was to determine changes in the quality characteristics of fixed and unfixed Pollock fillets during cold storage. The research object was refrigerated fixed and unfixed fillet of Pollock stored at a temperature below minus 18 degrees for up to 26 weeks. During storage the authors run organoleptic assessment on refrigerated, defrosted fillets after the cooking test. The results are the following: after 6 weeks of storage the organoleptic quality indicators are quite stable for all types of fillets; after 14 weeks there is a 40 % decrease in the overall score for the fixed fillet; moreover, there are the main changes in the samples after cooking for the most significant organoleptic indicators: color, taste, smell, consistency. After 14 weeks of storage the quality indicators of loose fillets remained almost unchanged. By the 14th week of storage the freshness value coefficient of the fixed fillet increases almost 3 times (from 14.8 to 40.0), i.e. a man can consume the fish only after mandatory cooking. The study identified that the operation of fixing fillet preserved the fillet block integrity, giving greater mechanical strength to the fillets, reducing the tissue juice loss, but it is inferior in organoleptic parameters to the loose fillet during storage reducing its shelf life. According to the experiment results, the researchers recommend a storage period for fixed frozen fillet of Pollock – up to 5 months, for loose fillet – up to 7 months without considering packaging materials.

Currently, eSports becomes particularly popular among young people. Computer sport induces significant loads on the human body, especially on the physiological and psychoemotional state. Tournament participants are to have a high degree of concentration and the ability to stay at a personal computer for a long time. These factors determine the need for increased energy consumption to maintain the body in a state of high activity. A man developed food products based on fundamental scientific achievements in the field of sports nutrition for athletes using special food technology. The high biological value of food products for eSports athletes makes them unique for maintaining active life in non-standard conditions and under increased loads during the preparation and conduct of competitions. To solve this problem, the authors performed mathematical modeling of the multicomponent culinary product recipe by the simplex method and automatization tools using the MS Excel software package. They chose the balance of essential amino acids as the optimization parameter. As a result of mathematical modeling, the researchers obtained eight ratios variants of the modified ingredients that meet the specified conditions. The replacement of bread wheat by the canihua is to improve the amino acids balance in proteins in the combined products. Organoleptic assessment of the culinary dish «Fish balls (steamed)», prepared according to the classic and developed recipes, allowed to conclude: the introduction of more than 34.0 % of canihua grain into the recipe has a negative impact on the product taste. The recipe optimization of a culinary product using canihua grain approved samples determination of multicomponent culinary products that corresponded to the selected parameters of the target function.

The article presents the study results of the antibacterial activity of rutin and quercetin, as well as flavonoids sum extract obtained from the fat-free common sea buckthorn meal (Hippophae rhamnoides L.), in comparison with the state standard sample (SSS) of rutin. According to one of the strategies for effectiveness and therapeutic potential evaluating of biologically active substances (BAS), a man studied the physicochemical parameters of fat-free sea buckthorn meal and the component composition of the flavonoid complex isolated from it. Inhibition of test microorganism cultures by the studied flavonoids showed that quercetin detected the maximum antibacterial activity against B. subtilis and B. mesentericus: the zones diameter of microbial growth suppression exceeds the lysis zones diameter of the SSS rutin comparison sample – 20.0 ± 0.1 mm and 16.0 ± 0.1 mm, respectively, whereas in SSS rutin – 1.0 ± 0.1 mm and 10.0 ± 0.1 mm. The researchers determined the quercetin influence on changes in morphological characteristics of B. subtilis and B. mesentericus by comparing micro-preparations, samples of which were taken from the area of bacterial growth after treatment with quercetin. Thus, the cells of the hay bacillus noticeably decreased in size, and the cells of the potato bacillus changed shape – from stringformed to coccoid-formed, indicating the cells forwardness to a quiescent state, which is a way of survival in the adverse conditions caused by quercetin treatment. To quantify the antibacterial effect of flavonoids, a man developed the inhibition coefficient (Ki) of microbial growth; its maximum value in the quercetin sample is 1900.0% for B. subtilis and 60.0 % for B. mesentericus, which allows to consider this sea buckthorn meal flavanol as a promising micro-ingredient for food bioconservation.

study objectives were: to analyze the balance between the expenditures level and the expenditures share of the family budget on food; to determine consumer preferences for types of processed cheeses, to study its price and quality, purchases frequency, and manufacturer’s choice; to identify the consumers attitude to innovations aimed at increasing the nutritional value of processed cheeses. The developed model for measuring the latent variable in the analysis of consumer preferences for processed cheeses formed the basis of the survey questionnaire. The authors conducted the sample survey in four administrative districts of Oryol. They used a questionnaire method to survey a part of the population, selected equally in the administrative districts. The analysis reveals the following data: more than 80.0 % of respondents regularly buy processed cheeses; more than 20.0 % rarely buy cheeses. When choosing cheeses, 50.0 % of respondents are subject to the price; about 40.0 % prefer the quality of cheeses, 12.0 % of this group are low-income respondents; 13.5 % of respondents said that they have purchased low-quality processed cheeses. According to the survey of the consumer demand level for processed cheeses with a probability of 0.997, the share of the Oryol population that may be interested in buying processed cheeses of high nutritional value with vegetable additives ranges from 80.2 to 92.8%, and the share of the population that regularly buys processed cheeses is from 75.8 to 88.3 %.

Objectives: We planned this study to find out morbidity patterns as well as outcome of admitted children aged less than 5 years of age with severe acute malnutrition (SAM). Study Design: Cross Sectional study. Setting: Department of Pediatrics Medicine, Ghurki Trust Teaching Hospital, Lahore. Period: From 1st January 2018 to 30th June 2018. Material & Methods: A total of 80 children aged 1 to 59 months, of both genders, having SAM were considered. Physical examination, detailed clinical as well as laboratory findings related to nutritional status and comorbidities were noted. Outcome in terms of recovery/discharge, left against medical advice (LAMA) or death during the stay was noted in all the children. Results: Out of a total of 80 children, 20 (25.0%) were aged 1 to 6 months, 39 (48.8%) from 7 to 24 months and 21 (26.2%) from 25 to 59 months. Most of the patients, 39 (48.8%) were from 7 to 24 months of age, 62 (77.5%) were admitted through emergency, 52 (65.0%) had WHZ score-4SD and 27 (33.8%) using bottle feeding. Severe wasting without having edema was reported in 67 (83.8%) children. Diarrhea was the commonest comorbidity, found in 43 (53.8%) children, followed by sepsis 17 (21.3%) and pneumonia 15 (18.8%). There were 69 (86.3%) children noted having anemia. Hyponatremia was the commonest metabolic abnormality seen in 40 (25.0%) children. In terms of outcome, 71 (88.7%) children recovered well and got discharged while mortality was reported in 5 (6.3%) children. Conclusion: Diarrhea along with sepsis and pneumonia along with metabolic abnormalities were found to be more prevalent amongst children having SAM. Early identification of anemia as well as infections in children with SAM can contribute to better outcome.

Objectives: Polycystic ovary syndrome (PCOS) is a rampant endocrine disorder distressing women of child bearing age worldwide. Many current researches have detected the presence of some organ specific and non-specific autoantibodies in females with PCOS. Study Design: Cross Sectional study. Setting:  Aziz Fatimah Hospital, Faisalabad, Pakistan. Period: April to September 2017. Material & Methods: This study comprised of 88 female subjects of 17-35 years old. Participants were divided into four group’s i.e PCOS obese females, PCOS non-obese, obese females without PCOS and age matched controls. Thyroid function was evaluated by the measurement of serum TSH, FT3 and FT4 levels. Thyroid peroxidase antibody was detected as an indicator of thyroid autoimmunity. All parameters were measured by chemiluminescence immunoassay technique (CLIA). SPSS version 22 was used for the statistical analysis of the data. Results: Out of total 88 female participants, 38.6% were hypothyroid and 61.4% were euthyroid females. While on comparing the percentages of hypothyroidism among the study groups PCOS, non-PCOS patients and obese we found higher percentages of hypothyroidism among non-obese PCOS. Thyroid peroxidase antibody levels were higher in PCOS obese subjects. PCOS patients have 15 times more risk for hypothyroidism as compared to non-PCOS patients. Conclusion: Hypothyroidism was commonly found in PCOS patients with high levels of TPO-Antibody indicating that PCOS is an independent risk factor for hypothyroidism which suggests that evaluation of thyroid function and autoimmunity must be deliberated in PCOS patients.

Setting: Department of Orthopaedic Surgery Dow University of Health Sciences / Civil Hospital Karachi. Period: From April 2014 to December 2018. Material & Methods: Seven patients with Chondrosarcoma pelvis included in this study. Results: All Seven patients were male. 2 patient age was in 20’s, three in 40’s and two in 60’s with median age of 44. Clinically presentation of patients was variable. One patient present with groin lump, one with pain and swelling lower abdomen, three with hip pain, one patient with severe gluteal pain and lump, one with massive lump extending from the mid abdomen to groin and urine retention and constipation. Five patients have left pelvis involved and two have right side. Two patients have pubic bone and ischium (Level III) involved, two have ilium (Level I) and three have ilium, acetabulum and pubis (Level I, II, III). Two patients with have preoperatively sciatic nerve palsy. Two patients have medical comorbid. One was asthmatic and one had psychiatric illness. No patient had metastasis at presentation. Pubis and ischium with tumor resected in two cases, partial ilium resection in one case, one complete P1 resection with sciatic nerve, one patient have internal hemipelvectomy and one patient had internal hemipelvectomy that bone recycled in liquid nitrogen and pelvis re-implanted and fixed with recon plates and hip joint reconstructed with total hip replacement. One patient had external hemipelvectomy due to pus at tumor site. Total duration of surgery in patient having thirteen hours, and remaining have 3 to 5 hours. Blood loss during these surgeries was in between 1000 to 1200 ml. Three patients have wound infection, one patient had L5 nerve root injury. Patient with external hemipelvectomy develop wound dehiscence and uro-cutaneous fistula. Two patients died, one with recycled bone after 15 months due cardiac problem and 2nd due to disease related complications within 3 months of surgery. Conclusion: Pelvic chondrosarcoma must be operated by the team of surgeons including orthopaedic surgeon, urologist and general surgeon because of the tumor presents with massive lumps due to unrestricted compartment and can involve the important pelvic organ. With team any complication can be prevented and treated immediately.

Objectives: To study antibiotic sensitivity pattern of Salmonella typhi in children with enteric fever. Study Design: Prospective, Consecutive sampling. Setting: Children Hospital and Institute of Child Health, Faisalabad. Period: 6 Months June 2019 to November 2019. Material & Methods: All admitted children of age 1-16 years with strong clinical suspicion of typhoid fever and with no comorbidities were included in this study. Blood cultures and other relevant investigations were performed to rule out other causes of fever. After identification of organism as Salmonella typhi, antibiotics susceptibility testing was done by disk diffusion technique and zones of inhibition were interpreted according to clinical and Lab standard (CLSI) guidelines. Results: Out of 60 patients maximum children were < 5 year and >10 year of age. Maximum cases were admitted during July to September. Male to female ratio was 1.6:1. We were able to send blood cultures of 31 cases (51%) only. Out of them 14 cases (45%) were found culture positive. All culture positive (100%) were found sensitive to meropenem. 92.8% were found sensitive to azithromycin and 7.1% were found sensitive to amikacin. Overall 16 cases treated with meropenem, 10 cases (16%) with azithromycin and one with amikacin. However, 33 cases (55%) responded to ceftriaxone alone. Conclusion: Sensitivity pattern of Salmonella typhi revealed significant proportion of multidrug and extensive drug resistant strain. So, continue surveillance is needed in this regard to find actual burden of XDR typhoid fever. We recommend local district administration and health authorities to launch an awareness campaign regarding sanitation, good hygiene, use of safe of water and mass vaccination of children with conjugated vaccine against typhoid. Alongwith above measures antibiotic stewardship should be started.
