title: Guidelines for managing complex department store construction projects based on Lean Production and Agile Project Management

description: Abstract Construction projects are becoming increasingly complex. Traditional project management approach does not consider all the complex attributes involved in some projects and assumes that there are general solutions for managing them, without taking into account the specific context in which they are situated. Therefore, there is a need to develop project management methods and tools that consider both the complexity involved and the characteristics of the context. The Lean Production philosophy and the Agile Project Management approach have been pointed out in the literature as two alternatives to support such projects. This paper aims to propose a set of guidelines for managing complex department store construction projects, based on the two theoretical perspectives mentioned above. Using Design Science Research as a methodological approach, an empirical study was carried out in a Brazilian department store enterprise, which is a construction client. The theoretical contribution of this paper is an analysis of the overlaps and complementarities between Lean Production and Agile Project Management.

title: INFLUENCE OF FEMORAL OFFSET ON FUNCTIONAL CAPACITY OF PATIENTS WITH TOTAL HIP ARTHROPLASTY

description: ABSTRACT Objective: To correlate vertical (VFO) and horizontal (HFO) femoral offset with hip range of motion (ROM), peak muscle torque (PT), functional, capacity, and lower limb length in patients with total hip arthroplasty (THA). Methods: A cross-sectional case control study, in which 22 individuals (10 men and 12 women) - aged 61 (41-72), and within 23 (10-40) postoperative days - were evaluated for active hip ROM (fleximetry); Isometric PT (portable dynamometer); functional capacity (Timed up and Go test (TUG) and Harris Hip Score questionnaire); lower limb length (measuring tape); and VFO and HFO (radiographs). Results: The operated limb showed a reduction in length (p = 0.006), ROM for abduction (p = 0.001), flexion (p = 0.003), and external rotation (p = 0.003), as well as in all PT (p &lt; 0.05) when compared with the contralateral limb. Moderate correlations were observed between VFO and external rotators (r = 0.487; p = 0.021); HFO and external rotators PT (r = −0.508; p = 0.016); and the difference between the VFO (operated and non-operated limb) and the TUG (r = −0.570; p = 0.006). Conclusion: Changes to the femoral offset seem to influence functional capacity, as well as the movement and external rotators PT of the hips in patients with THA, considering the postoperative period evaluated. Level of Evidence III, Case Control Study.

title: Phase change materials in building systems: an integrative literature review

description: Abstract Phase Change Materials (PCMs) have a high latent heat storage capacity and the potential to provide thermal comfort to users and energy savings in buildings. However, many parameters must be analysed for the adequate selection and application of these materials. This article discusses the potential of applying PCMs in construction systems based on an Integrative Literature Review of national and international publications, identifying the classification, selection, incorporation and application criteria, trends, and research gaps. The review covers 134 articles, 103 of which are state-of-the-art from the past five years. Most of the research studies examined demonstrate that using PCMs in constructive systems leads to increased comfort hours and lower energy consumption. Climate conditions proved to be the most crucial parameter for an adequate choice of PCMs, highlighting a gap in the research on tropical regions with hot and humid climates and low latitudes, such as a large portion of Brazil. This study also detected a significant growth in research using multi-objective simulations and optimisation to simultaneously evaluate the parameters involved in the association of PCMs and building systems.

title: Phenolic profiling, organic acids and sugars composition of feijoa (Acca sellowiana (O. Berg) Burret) and uvaia (Eugenia pyriformis Cambess) from the southern Brazilian highlands

description: ABSTRACT: Brazil is a large country with high biodiversity in its different regions. However, species of native fruits widely reported in the southern Brazil have not been properly explored so far, remaining underutilized by the food industry. This study evaluated the polyphenolic profile, as well as the composition of organic acids and sugars of the pulps of the feijoa, and the uvaia from southern brazilian highlands. The uvaia pulp showed the highest total polyphenol content and the highest antioxidant capacity by the methods used. The polyphenol (+)-catechin (6.54 mg 100g-1) was the major phenolic compound in uvaia pulp, which has not yet been reported in the literature for fruits of other regions. In addition, the feijoa pulp stood out for the presence of (-)-epicatechin (18.29 mg 100g-1). The pulps of native fruits in this study only quantified values for citric and malic acids. Malic acid (553.00 mg 100g-1) was the main acid in the uvaia pulp, and citric acid (455.60 mg 100g-1) was the main acid in the feijoa pulp. It is possible to note that the feijoa pulp showed the highest total sugar content (11.14 g 100g-1) and was the only pulp that contained sucrose. The uvaia pulp, conversely, showed fructose (3.10 g 100g-1) as the main sugar. The results obtained in this study contributed to the valuation and conservation of the species investigated, representing a promising alternative for the use of these native fruits in the development of new products.

title: FRAGILITY FRACTURES IN BRAZIL: CROSS-SECTION STUDY

description: ABSTRACT Objective: To evaluate the involvement of orthopedists and orthopedic residents with fragility fractures, in its clinical, therapeutic, and social aspects. Methods: Cross-sectional observational and prospective study that took place in the period from June to August 2020. Results: 540 participants were analyzed. The population consisted of orthopedists (85.56%; N = 462) and residents (14.44%; N = 78), with a greater proportion of individuals from 41 to 50 years of age (36.67%; N = 198) and from the Southeast region (57.22%; N = 309). For 47.04% (N = 254) of the participants, the profile of the patient at risk for fragility fracture corresponds to: woman, sedentary, smoker and over 60 years of age. The consensus among the participants (97.96%; N = 529) is that fragility fractures occur in or near home environments. Moreover, 47.59% (N = 257) believe that the first fragility fracture is the most important predictive risk factor for subsequent occurrences and 63.89% (N = 345) of the participants claim to attend more than 15 cases per year. Regarding treatment, 74.44% (N = 402) are dedicated exclusively to orthopedic aspects (68.33%; N = 369). However, 62.41% (N = 337) of the participants believe that patients with fragility fractures should receive medication and supplements. Likewise, 70.74% (N = 382) of the participants consider that home security measures and training of family members are important, and they attribute the role to the multidisciplinary team. Conclusions: Fragility fractures are frequent in the routine of Brazilian orthopedists. However, they are not familiar with adjuvant treatments for fragility fractures, acting almost exclusively in the orthopedics aspects of these injuries. Level of Evidence II, Prospective Study.

title: Genome-Wide Association Study on Two Immune-Related Traits in Jinghai Yellow Chicken

description: ABSTRACT This study was designed to discover molecular marker associated with the interferon INF-γ and avian influenza (AI) antibody titer traits in Jinghai Yellow chicken (Gallus gallus). Serum samples were taken from 400 female chickens and the INF-γ concentrations and AI antibody titer levels were measured. A genome-wide association study was carried out using specific-locus amplified fragment (SLAF) sequencing. Bioinformatics analysis was applied to detect single-nucleotide polymorphisms (SNPs) associated with the two traits. After sequencing and quality control, 103,680 SLAFs and 90,961 SNPs were obtained. The 400 samples were divided into 10 subgroups to reduce the effects of group stratification. The Bonferroni adjusted P-value of genome-wide significance was set at 1.87E−06 according to the number of independent SNP markers and linkage disequilibrium blocks. A SNP that was significantly associated with INF-γ concentration was detected in the myomesin 1 (MYOM1) gene on chromosome 2, and another SNPthat was significantly associated with the AI antibody titer level was detected in an RNA methyltransferase gene (Nsun7), which was found to have an important biological function. We propose that MYOM1 and Nsun7 are valuable candidate genes that influence the disease resistance characters of chicken. However, in-depth investigations are needed to determine the essential roles of these genes in poultry disease resistance and their possible application in breeding disease resistant poultry.

title: Models for early cost estimating using linear regression: penitentiary projects modeling

description: Abstract Early cost estimation of construction projects is not an easy task, as such projects involve a high level of inaccuracy and uncertainty. Even in the early stages, errors in the estimates can result in financial loss and jeopardize construction completion. Therefore, the main objective of this research study is to present a framework for building cost estimation models, using the linear regression technique. The framework method is divided into five phases: (1) identifying the model’s requirements, (2) selection of the independent variables, (3) database construction, (4) data modelling and (5) model performance evaluation. A case study was conducted on federal penitentiary construction projects to test the applicability of the framework. Through the case study, two valid models were built, and their margins of error were 23 and 25%. The framework itself is one of the main contributions of this study, and it can be replicated by practitioners to develop models for construction cost estimation.

title: The benefit of Silybum marianum in ethanol-induced reprotoxicity of male Wistar rat

description: Abstract This study investigates the toxic effects of ethanol (Eth) on the reproductive system of male rats and the possible protective role of Silybum marianum seeds-infused solution (SMI) over six consecutive weeks of administration. Animals were divided into the following groups: control, SMI positive control (200 mg/kg/day), Eth1 (1 g/kg/day), Eth2 (2 g/kg/day), Eth1+SMI, and Eth2+SMI. Plasma testosterone concentration, epididymal spermatozoa biology, and testicular and epididymal MDA, GSH and GPx levels were evaluated. The results indicated a significant decrease in testis and epididymis weight, testosterone level, sperm concentration, sperm vitality and sperm motility (total motility, progressive motility, curvilinear velocity, straight-line velocity, velocity average path, beat cross frequency, and lateral head displacement) in both Eth1 and Eth2 compared to the control groups and the combined-treatment groups (Eth1+SMI and Eth2+SMI). Furthermore, results showed a significant elevation in MDA concentration with a significant decrease of testicular and epididymal GSH concentration and GPx activity in theEth1 and Eth2 groups compared to the combined-treatment groups. The administration of SMI succeeded in improving the parameters cited above in the combined-treatment groups compared to the Eth1 and Eth2 groups, and bring them to the levels seen in the control groups. To conclude, SMI has clearly protected reproductive indices against ethanol-induced reprotoxicity in male rats
