Encountering Goddesses in Late Antiquity: Notes on Metamorphoses of Mythic Figures in Religious Storytelling
Authors: Kiperwasser Reuven , Ruzer Serge
Published: April 2023

ABSTRACT: The imagined universe of the people of Late Antiquity was heavily populated by gods. Even the broader philosophical trends and monotheistic foundation of Judaism and Christianity had failed to entirely diminish their power. How then did Jews and Christians cope with such a backdrop presence of “other gods”? Earlier research suggested that Jewish attitudes, which found their way into early Christian sources as well, fluctuate between accommodation and rejection. Following analysis of Jewish and Christian Late Antique literary traditions dealing with gods, and more specifically, goddesses, this article aims to demonstrate that such “fluctuation” resulted – in addition to the extreme positions – in a variety of middle of the road strategies. These strategies point to a keen harmonizing impulse to absorb—via domestication—motifs with mythic religious vitality from the broader cultural repository.
Trees Die from the Top: A Case Study of Conflict Among the Board, Board Chair, and Executive Director
Authors: Mathews Melissa A.
Published: April 2023

This instructional case study based on historical data is intended for learners to examine critical incidents that led to conflict among the board of directors, board chair, and executive director of a nonprofit cultural arts organization, which is located in a major metropolitan region of the United States. The data collection methods for this study included archived meeting minutes, memorandums, field notes by the former executive director, and semi-structured interviews with nonprofit colleagues who were executive directors at other organizations during the study period. This instructional case study reveals multiple key departures from board governance policies and normative practices that led to board, board chair, and executive director conflict, resulted in organizational instability, and culminated in the firing of the executive director and resignation of the board chair. Additionally, this case provides an opportunity for learners to gain an enhanced understanding of ethical board practices and the value of community constituency involvement in broader governance processes.
Credentialing the Nonprofit Professional A Focus on the Campus Partner Track of the Nonprofit Leadership Alliance
Authors: Pinter Abbie N. , Powell Emma A. , English Kira , Poley Logann , Dilg Lizzie
Published: April 2023

The growing need for formal instruction for nonprofit professionals in the social sector has increased since the mid-1980s. Colleges and universities alike have tried to address this issue through curriculum alone; however, research continually shows the value credentials, and service-based learning adds to developing sector-based knowledge. This study evaluates the Campus Partner Track offered through the Nonprofit Leadership Alliance available to college campuses across the nation. Through this track, eligible students can earn their Certified Nonprofit Professional (CNP) credential, ensuring they master eight general competencies essential to success in the nonprofit sector. Prior research has shown that those obtaining their CNP are seven times more likely to rise to a leadership position in the sector, while reducing the learning curve on the job by 2 years. To further explore the effects of the CNP credential, data is used from surveys distributed to current Campus Partners reporting on variables needed to create a flourishing CNP Program on college campuses, factors that are beneficial to students, and the overall value of the CNP credential to young professionals entering the workforce. Results indicate that internships, coursework, and professional experience opportunities are all vital in bolstering the educational learning of nonprofit students in higher education.
Mental illness and destigmatization: the case of Sidi Chami psychiatric hospital of Oran, Algeria
Authors: Benharrats Sarra Samra
Published: April 2023

The definition of mental illness, the description of the experience of the subject affected by this disorder, and the decision of what is necessary for the experience of the carrier of this illness are always established by the "healthy" subject, who himself has certainly not experienced living mental illness. In this regard, it is rare and unlikely to refer to the person having this disorder, even if he is completely stabilized and in remission. The patient suffering from mental disorders defines and expresses his disease, and social sufferings secondary to his malaise, in several forms ranging from words to carrying his voice, to destigmatizing himself. In this article, a qualitative study, based on the interpretation of speech and the observation of behavior, we illustrate some cases of subjects with mental disorders followed up at the Sidi Chami Psychiatric Hospital of Oran in Algeria. These patients, as a result of their resilience, have been able to open a new path toward destigmatization.
Zachowania gestyczne i wrażenia olfaktoryczne literackich i filmowych transbohaterów
Authors: Kujawska-Kot Anna
Published: April 2023

Artykuł podejmuje problem niewerbalnych form komunikowania tożsamości płciowej przez bohaterów transseksualnych. Takie aspekty pretranzycji i tranzycji, jak zachowania gestyczne i uzewnętrznienie swojej płci psychicznej przez dobór odpowiedniego zapachu, były zwykle lokowane na marginesie naukowych dociekań. Jednak adekwatnie wyselekcjonowane fragmenty literackie i filmowe stanowią odpowiedni materiał badawczy do przybliżenia takich kwestii, jak rola gestów, mimiki, sposobów chodzenia, znaczenia mikro-ruchów twarzy, wybór perfum. W artykule podjęto próbę odpowiedzi na następujące pytania badawcze: w jaki sposób gesty, mimika, sposoby chodzenia, a nawet dobór perfum bohaterów transseksualnych kształtują płciową (re)prezentację w przestrzeni publicznej? Jakie funkcje pełnią zachowania gestyczne, mikro-ruchy twarzy, perfumy w niewerbalnym komunikowaniu tożsamości płciowej przez transkobiety, jak również transmężczyzn? W badaniu tekstów kultury zastosowano technikę montażu. Okazuje się, że bohaterowie różnym drobiazgom – w procesie autokreacji i w reprezentowaniu swojej tożsamości płciowej – nadają istotne znaczenia. Transkobiety i transmężczyźni tekstualizując siebie, z jednej strony często fetyszyzują własną twarz, z drugiej zaś doświadczanie własnego oblicza może zdumiewać subtelnością i synestezyjnym charakterem. W ich ciałoteksty - ukierunkowane na zaznaczenie przynależności płciowej – wpisane są celowo dobrane zachowania gestyczne, perfumy. Wybory te, choć odwołują się do stereotypowej mowy ciała kobiety lub mężczyzny oraz ich zapachu, nie mają wydźwięku pejoratywnego. Zmienia się status ontyczny stereotypu. Staje się on inspiracją, drogowskazem i nośnikiem komunikacji.

Authors: Grzeszczyk Agata
Published: April 2023

W niniejszym artykule została podjęta problematyka etykietowania osób przerywających ciąże, świadczących usługi aborcyjne, poszukujących informacji o aborcji czy też popierających zabieg przerywania ciąży. Celem artykułu jest próba odpowiedzi na pytania, w jaki sposób dokonuje się - według aktywistek publikujących na Instagramie - naznaczenie tych, którzy promują lub podejmują praktyki reprodukcyjne niezgodne z dominującą normą, jak radzą sobie instagramerki ze stygmatyzowaniem, jak jest przez nie określana kontrola reprodukcji oraz w jaki sposób jej doświadczają. Odpowiedzi na powyższe pytania udzielono na podstawie analizy treści postów zamieszczanych od 1.10 do 1.12.2020 r. na trzech feministycznych kontach instagramowych o największych zasięgach (mierzonych liczbą odbiorców).
Kroniki wojny rosyjsko-ukraińskiej. Perspektywa socjologa
Authors: Czernysz Natalia
Published: April 2023

Wczesnym rankiem 24 lutego 2022 roku Rosja rozpoczęła, zakrojoną na szeroką skalę, agresję na Ukrainę. Niemal natychmiast rozwinęła się współpraca socjologów Ukrainy i Polski, a konkretnie z Lwowskiego Uniwersytetu Narodowego i Uniwersytetu Wrocławskiego, w celu zrozumienia nowej rzeczywistości społecznej, która ukształtowała się od tego czasu w ich państwach i na świecie. Ważnym elementem tej współpracy było wydanie szeregu biuletynów, które zostały przygotowane przez przedstawicieli Katedry Socjologii Lwowskiego Uniwersytetu Narodowego im. Iwana Franki. Koledzy z Uniwersytetu Wrocławskiego przetłumaczyli je na język polski i angielski, i zamieścili na stronie internetowej swojej uczelni. Socjologowie lwowscy postawili sobie za zadanie informowanie opinii publicznej w Polsce, i za jej pośrednictwem w innych krajach, o przebiegu wojny rosyjsko-ukraińskiej w jej „gorącej” fazie oraz o stanie opinii publicznej w Ukrainie, a także o refleksjach teoretycznych, które powstają na gruncie aktualnych badań empirycznych. Jednym z naszych pierwszych uogólnień była teza: „socjologia to także broń”.

Authors: Dewi Gita Normala , Karunika Anindya Ramadian , Trisihono
Published: April 2023

Introduction: Mechanical ocular trauma is a major cause of ocular morbidity and can lead to severe visual loss. One of the most complicated mechanical ocular trauma is iridodialysis. In this case, we report three surgical procedures to treat the effect of mechanical ocular trauma. Case Presentation: A 32-year-old man was referred to Gatot Soebroto National Army Hospital, Jakarta, with major complaints of pain and blurred vision in the left eye after sustaining blunt trauma while playing tennis two days ago. He was diagnosed with postoperative corneal laceration repair, subtotal iridodialysis, traumatic cataract, and vitreous hemorrhage on his left eye. He underwent iridodialysis repair with the McCannel suture technique and continued with a pars plana lensectomy to remove the lens and a pars plana vitrectomy to treat the vitreous hemorrhage. Postoperative examination showed a significant improvement of best-corrected visual acuity (BCVA) from hand movement to 0.15 and no sign of acquired infection. Conclusions: The effect of mechanical ocular trauma might be unpredictable and may include various conditions. Accurate management will prevent further complication and improves the patient’s quality of life. A good approach and visual result will satisfy both patients and doctors.

Assessment decisions of independent learning activities using SMART–FCM method
Authors: Saputra Pelsri Ramadar Noor , Aslamiyah Sulaibatul , Chusyairi Ahmad
Published: April 2023

Sekolah Tinggi Ilmu Komputer (STIKOM) PGRI Banyuwangi implemented the Independent Learning - Independent Campus (MBKM) activity for two semesters. The results of student assessments for MBKM activities for one semester are influenced by the results of daily and weekly logbook monitoring, monitoring and evaluation assessments, and assessments of supervisors, examiners, and work partners. Assessments that are less objective cause many students to get good grades even though the implementation of MBKM activities is not well. The Simple Multi-Attribute Rating Technique (SMART) method is used to produce student eligibility group data and a more objective assessment. The results of the SMART calculations are combined with the Fuzzy C-Means (FCM) algorithm so that the results of grouping student data are more appropriate based on the similarities and characteristics of the members. Silhouette Coefficient is used to compare the grouping results. The results obtained that the use of SMART-FCM is better than the SMART results because it has a Silhouette Coefficient value close to 1 of 0.31187.

Post-decompression Disc Herniation - A More Common Complication. Comparison Between Minimally Invasive and "Mini-Open" Techniques
Authors: Uri Ofir , Alfandari Liad , Folman Yoram , Keren Amit , Smith William , Paz Inbar , Behrbalk Eyal
Published: April 2023

Background Index level disc herniation following lumbar spinal decompression is somewhat overlooked as postoperative complication, resulting in return of symptoms. It is proposed that the combination of local instability and degenerated disc is more likely to result in disc herniation. There is no literature comparing post-decompression disc herniation rates between different techniques. Purpose This study compares the postoperative disc herniation rates of the "mini-open" laminectomy versus the tubular system decompression. Study Design/Setting Retrospective comparative study Patient Sample 563 patients who underwent primary lumbar spinal decompression in our institution between February 2015 until September 2020. Outcome Measures Primary: comparison of post-decompression surgery, index level, disc herniation occurrence between two surgical techniques. Methods Patient files were retrospectively reviewed and divided into two groups, distinguished by surgical technique, "mini-open" partial laminotomy and minimally invasive surgery using tubular system. Demographic, clinical, and postoperative data were collected and compared using independent two-tailed t-test and Fisher's exact test with significance set at p<0.05. Results Postoperative index level disc herniation was significantly lower in the minimally invasive surgery group with 2 cases (0.8%) versus 19 cases (5.8%) in the "mini-open" group [p=0.002]. Disc herniation following single level and multi-level operations were also significantly lower in the minimally invasive group compared with the "mini-open" group (2 versus 11 and 0 versus 8 respectively; p<0.05). Conclusion Postoperative index level disc herniation following lumbar spinal decompression occurs in 3.7% of surgeries. Minimally invasive surgery is found to result in less herniations then "mini-open".
Eelgrass functions, services, and considerations for compensatory mitigation
Authors: Altman Safra , Balazik Matthew , Thomas Catherine
Published: April 2023

Coastal-marine eelgrass habitat is a critical resource within New England and throughout the world. Eelgrass habitat provides functions and services including providing structure, biogeochemical cycling, erosion reduction, habitation provision, and water quality improvement. Declines in eelgrass distribution are often due to anthropogenic processes impacting temperature and water quality. Declines in distribution and abundance highlight the importance of protecting the existing eelgrass, improving environmental conditions allowing for ecosystem restoration, and identifying viable in-kind and out-of-kind compensatory mitigation measures. Considering the limited availability of New England sites for in-kind compensatory mitigation, additional approaches for out-of-kind compensatory mitigation should be considered. These include (1) creation of alternative plant or kelp habitat, (2) using a multi-pronged, multi-habitat and structure approach, (3) contributing to the development of water quality improvement initiatives to encourage current eelgrass bed expansion over time, (4) reduce physical impacts to eelgrass habitat, (5) and identifying locations for future eelgrass habitat suitability based on climate predictions and investing to create future compensatory mitigation habitat in these locations.

South–South Trade and Economic Growth: Panel Data Evidence from Africa’s Market Integration
Authors: Musila Jacob , Yiheyis Zelealem
Published: April 2023

Policymakers in the South have initiated several regional trading schemes in the last four decades aimed at increasing South-South trade, believing that it will help achieve rapid economic growth and development. Although many analysts have examined the effect of regional trade arrangements on South-South trade, little is known about the impact of South-South trade on economic growth of the member states. This paper uses panel data for the period 1995-2020 to estimate the impact of intra-African trade on economic growth of 42 African countries. Using residual trade openness as instruments and PMG-ARDL-VEC estimation approach, we obtain positive and statistically significant long run relationship between growth of real GDP per capita and the proxy for intraAfrican merchandise trade intensity. We also obtain a positive and significant long run relationship between growth and proxiesfor extra-African merchandise trade openness and total trade openness. Although the results suggest that both regional and multilateral trade expansion can help spur Africa’s growth, the impact of extra-African merchandise trade on growth is, however, relatively higher than that of intra-African merchandise trade. Besides trade, we also find our proxies for physical and human capital accumulation to have significant and positive influences on real GDP per capita growth. JEL: C33, F15, O47, O55
Implications of environmental constraints in hydropower scheduling for a power system with limited grid and reserve capacity
Authors: Schäffer Linn Emelie , Korpås Magnus , Bakken Tor Haakon
Published: April 2023

The negative impacts of power systems on biodiversity have to be mitigated, while simultaneously ensuring affordable and secure electricity supply for the future. This may lead to trade-off situations where ecological, recreational or social needs are weighted against the need for flexible power supply. This paper explores the interaction between the security of electricity supply and environmental constraints on the operation of flexible hydropower plants in the Norwegian renewable-based power system. A long-term, stochastic scheduling model of a wind- and hydropower-dominated power system is used to assess the implications of environmental constraints and reserve capacity requirements in combination. The model is used for a representative case study where three types of environmental constraints are imposed on the operation of the hydropower plants in a region of the congested Norwegian power system. In addition, requirements for spinning and non-spinning reserve capacity have to be met. The case study results demonstrate varying impacts on the operation of the hydropower plants, curtailment of demand and provision of reserve capacity depending on the type of environmental constraint being imposed.
Mesenchymal stem cells in synovial fluid increase in number in response to synovitis and display more tissue-reparative phenotypes in osteoarthritis
Authors: Furuoka Hideto , Endo Kentaro , Sekiya Ichiro
Published: April 2023

Background
Synovial fluid mesenchymal stem cells (SF-MSCs) originate in the synovium and contribute to the endogenous repair of damaged intra-articular tissues. Here, we clarified the relationship between their numbers and joint structural changes during osteoarthritis (OA) progression and investigated whether SF-MSCs had phenotypes favorable for tissue repair, even in an OA environment.
Methods
Partial medial meniscectomy (pMx) and sham surgery were performed on both knees of rats. SF and knee joints were collected from intact rats and from rats at 2, 4, and 6 weeks after surgery. SF was cultured for 1 week to calculate the numbers of colony-forming cells and colony areas. Joint structural changes were evaluated histologically to investigate their correlation with the numbers and areas of colonies. RNA sequencing was performed for SF-MSCs from intact knees and knees 4 weeks after the pMx and sham surgery.
Results
Colony-forming cell numbers and colony areas were greater in the pMx group than in the intact and sham groups and peaked at 2 and 4 weeks, respectively. Synovitis scores showed the strongest correlation with colony numbers (R = 0.583) and areas (R = 0.456). RNA sequencing revealed higher expression of genes related to extracellular matrix binding, TGF-β signaling, and superoxide dismutase activity in SF-MSCs in the pMx group than in the sham group.
Conclusion
The numbers of SF-MSCs increased in response to synovitis in a rat OA model. Tissue-reparative gene expression patterns were observed in SF-MSCs from OA knees, but not from knees without intra-articular tissue damage.
Harnessing Education & Lifestyle Change to Support Transitional Health for Returning Citizens: A Feasibility Study Protocol
Authors: Sneed Rodlescia S. , El-Alamin Leon , Thrower Marsha , Nadrowski Jessica , Habermehl Kayla
Published: April 2023

Background
Exercise and healthy eating are known to reduce chronic disease risk; however, formerly incarcerated individuals (i.e., returning citizens) face significant social barriers when attempting to engage with existing community-based physical activity and nutrition programs. Given the high disease burden and unique educational needs of returning citizens, this proposed work fills an important gap in the support services currently offered to this population.
Methods
This article describes a process for evaluating the feasibility and acceptability of a physical activity and nutrition intervention tailored to the needs of returning citizens via a partnership between an academic research organization and a community-based reentry program for returning citizens. Staff from the community-based reentry program will train four returning citizens as group fitness instructors and work with a nutritionist to design a 16-week nutrition education curriculum. Reentry program staff will enroll up to 15 formerly incarcerated adults (aged 18+) in the exercise and nutrition program. Participants will take part in weekly nutrition classes led by the nutritionist and weekly group exercise classes led by a peer instructor. Research staff will evaluate program success in four domains: reach, preliminary effectiveness, implementation, and maintenance.
Results
This feasibility study will allow us to design and test a program that can eventually be evaluated in a large, randomized trial. It also addresses the multitude of social determinants that impact the health of returning citizens and builds a framework for program sustainability. Individuals recruited as fitness trainers will acquire skills and certifications that may be used to sustain physical fitness activities within the reentry program
Conclusions
This feasibility study will test our ability to address social determinants that impact the health of returning citizens through a peer-led physical activity and nutrition programming. In the long term, study results may inform development and implementation of reentry programming and policy on a wider scale.
A Sustainable Urban Engineering Complexity: The Built Environment-Induced Urban Heat Island Effect in Rapidly Urbanizing Regions
Authors: Maruthu Mugesh , Shanmugavel Durgadevagi
Published: April 2023

Increased development in the front of infrastructural activities, something that is especially being witnessed in developing countries in the past few decades, has resulted in unforeseen increases in urban air temperatures. The study was conducted to get the various urban infrastructure measurements used to assess the Urban Heat Island (UHI) effect. Shrinking vegetation in urban spaces also plays a significant role. Hence, vegetation metrics have also been studied to provide a holistic interpretation of the phenomena. Overall, the studies indicate that increasing albedo values and vegetation can reduce UHII. A reduction in building density, urban size, and population can play a role in reducing UHII. Building height, Canyon H/W, and SVF need to be optimized to achieve UHI mitigation. A study conducted in 5 cities in Tamil Nadu revealed that the city with the highest population density recorded the highest average daily high dry bulb temperature (DBT). However, further cities did not follow a similar pattern. Hence, the importance of studying various metrics in tandem is important to understand the climate wholistically. The research gap identified in the studies shows the need to study material properties other than just albedo values. These may include thermal conductivity, diffusivity, emissivity, heat evolution, and rheological properties of materials, along with physical and mechanical properties. There is a potential for a part of sustainable development goals to be met through enhancing material properties that can mitigate the UHI effect.

Freshwater wetlands are interesting habitats for methane-oxidizing bacteria or methanotrophs. We isolated a methanotroph, strain WWC4, from the mud of a freshwater creek running close to a beach in the coastal regions of Western India, near Alibag town. Strain WWC4 was a strict methanotroph, thriving only on methane and marginally on methanol. It formed pink to slightly orange-colored round colonies and formed pinkish turbidity or surface pellicle in liquid culture, indicative of the Methylomonas genus. The strain is characterized by thick, short, and motile rods, 2.5-3 µm long and 0.8-1.2 µm wide in size, with a Gram-negative character. Based on the 16S rRNA gene sequence, the culture was classified as a Methylomonas strain, with the nearest type species being Methylomonas koyamae Fw12E-YT showing 97.81% sequence similarity. A comparison of the draft genomes indicated that Methylomonas sp. WWC4 genome showed only 74.45%, 75.72%, and 21.5% similarities of AAI, ANIb, and dDDH values, respectively, with its closest neighbor Methylomonas koyamae Fw12E-YT, indicating its taxonomic novelty at the level of species. The GC content of the genome was 55.9 mol%. The whole-genome shotgun project was deposited at DDBJ/ENA/GenBank, and the accession number is JAATWI01.1. The cell wall lipids indicated a unique fingerprint with 15:1 ω8c (21.09%), 16:0 3OH (15.7%), and 16:1ω5c (12.6%) being the primary fatty acids, dissimilar to any other related Methylomonas species, confirming its taxonomic novelty. The genome was further explored for carotenoid pathways and plant growth promotion genes for its biotechnological potential. Strain WWC4 did not withstand cryopreservation and could not be deposited in two international culture collections. The culture is part of our institutional, WDCM-approved culture collection as MCMB-1474, maintained live. Due to its taxonomical novelty, strain WWC4 is also proposed to be a member of a Candidatus species of the Methylomonas genus and named “Candidatus Methylomonas sedimenticola” strain WWC4.

Race Ug99 of Puccinia graminis f. sp. tritici (Pgt), the causal agent of wheat stem (or black) rust is one of the most serious threats to global wheat production. The identification, mapping, and deployment of effective stem rust resistance (Sr) genes are critical to reduce this threat. In this study, we generated SrTm4 monogenic lines and found that this gene confers resistance to North American and Chinse Pgt races. Using a large mapping population (9,522 gametes), we mapped SrTm4 within a 0.06 cM interval flanked by marker loci CS4211 and 130K1519, which corresponds to a 1.0-Mb region in the Chinese Spring reference genome v2.1. Physical map of the SrTm4 region was constructed with 11 overlapping BACs from the resistant T. monococcum PI 306540. The comparison of the 754-kb physical map with the genomic sequence of Chinese Spring and the discontinuous BAC sequence of DV92 revealed a 593-kb chromosomal inversion in PI 306540. Within the candidate region, we identified an L-type lectin-domain containing receptor kinase (LLK1), which was disrupted by the proximal inversion breakpoint, as a potential candidate gene. Two diagnostic dominant markers were developed to detect the inversion breakpoints. In a survey of T. monococcum accessions, we identified only 10 domesticated T. monococcum subsp. monococcum genotypes, mainly from the Balkans, carrying the inversion and showing similar mesothetic resistant infection types against Pgt races. The high-density map and the tightly linked molecular markers developed in this study are useful tools to accelerate the deployment of SrTm4-mediated resistance in wheat breeding programs.

Published: April 2023

Aiming at the problem of the wear caused by the mutual movement between the convex die and the sheet material in the stamping process, which results in a decrease in the die service life. In the paper, the three-dimensional design of the drawing die for the outer plate of the rear wheel cover was carried out by using UG, the simulation of the die stamping process was carried out by using Deform-3D, the main wear positions of the die were determined, the four process parameters of die clearance, friction coefficient, stamping speed and die hardness were selected as the test factors, the amount of die wear was used as the evaluation index to establish an orthogonal test, the multiple linear regression analysis of the test results was carried out by using SPSS software, and the empirical formula for the surface wear of the drawing die was established. Finally, the BP neural network model between process parameters and wear amount was constructed using MATLAB. The weights and thresholds of the nodes in the implicit layer of the model were optimized by using the whale algorithm to obtain the optimal combination of process parameters with minimum wear amount predicted based on the optimized WOA-BP neural network model. The minimum wear amount of the optimized convex die was 1.02×10-6 mm. The optimal combination of process parameters was friction coefficient 0.12, stamping speed 22mm/s, die hardness 62HRC, and die clearance 0.88mm, which completes the design of the automotive rear wheel cover outer plate drawing die and optimizes its surface wear process parameters.

Introduction Postoperative pulmonary complications (PPCs) are prevalence in geriatric patients with hip fractures. Low oxygen level is one of the most important risk factors for PPCs. Prone position has been proven efficacy in improving oxygenation and delaying the progress of pulmonary diseases especially in patients with acute respiratory distress syndrome induced by multiple etiologies. The application of awake prone position (APP) has also attracted widespread attention in recent years. A randomized controlled trial (RCT) will be carried out to measure the effect of postoperative APP in a population of geriatric patients undergoing hip fracture surgery.
Methods This is a RCT. Patients older than 65 years old admitted through the emergency room and diagnosed with an intertrochanteric or femoral neck fracture will be eligible for enrollment and randomized to control group with routine postoperative management of orthopedics or APP group with additional prone position for the first three consecutive postoperative days (PODs). Patients receiving conservative treatment will not be eligible for enrollment. We will record the difference in patient’s room-air-breathing arterial partial pressure of oxygen (PaO2) values between the 4th POD (POD 4) and emergency visits, morbidity of PPCs, mortality and ICU stays during hospitalization, length of hospitalization. The rates of PPCs, readmissions and mortality will be followed up for 90 PODs.
Discussion
We describe the protocol for a single-center RCT that will evaluate the efficacy of postoperative APP treatment in reducing pulmonary complications and improving oxygenation in geriatric patients with hip fracture.

Background and aim: Bowel preparation is a crucial factor affecting the diagnostic accuracy of colonoscopy, and few randomized control trials evaluated enhancement in bowel preparation. In this study, we aimed to evaluate the effectiveness of walking exercises on bowel preparation before colonoscopy procedure.
Methods: The present study is a single-blind randomized control trial, including 262 patients undergoing colonoscopy procedure. Patients were randomly divided into two groups of intervention (n=131) and control (n=131). Individuals in the intervention group were supposed to consume certain liquids and foods, bisacodyl pills, poly ethylene glycol powder and walk before their colonoscopy day based on a predefined plan. Individuals in the control group were supposed to consume the same regimen as the intervention group but were not told to do walking exercises. On the colonoscopy day, both groups were estimated regarding the number of footsteps taken by a foot counter. An experienced gastroenterologist compared the two groups regarding the Boston Bowel Preparation Scale (BBPS).
Results: The number of taken footsteps in the two groups was significantly different (P<0.001). Although there was no significant difference between the intervention and control groups regarding mean BBPS (6.26±1.9 vs 6.29±1.9, P =0.416), individuals with more than 6900 steps had significantly higher BBPS compared to individuals with less than 6900 footsteps (6.62±1.8 vs 5.92±1.9, P = 0.003). In univariate analysis, BBPS was significantly associated with age below 50 (OR: 2.45, 95%CI: 1.30-4.61, P=0.006) and smoking (OR: 0.41, 95%CI: 0.17-0.94, P=0.043). In multivariate analysis, the relationship between BBPS with age below 50 and smoking remained significant (OR: 2.50, 95%CI: 1.30-4.70, P=0.005 and OR: 0.38, 95%CI: 0.16-0.93, P=0.034, respectively).
Conclusion: Although walking exercise as an intervention before colonoscopy was not significantly associated with BBPS, the higher number of footsteps taken was found to enhance bowel preparation. Also, older people and smokers seem to have fewer benefits from walking exercises for bowel preparation before the colonoscopy procedure.
