Effect of anisotropic abrasive damage on mass loss and ultimate tensile properties of the stretch denim fabric
Authors: Mukhopadhyay Arunangshu , Shaw Vivek Prasad 
Published: May 2022

PurposeIn recent times, stretch denim garments have become very popular amongst consumers as the garment is able to provide body fit and body comfort at the same time. The purpose of this study is to investigate the effect of abrasion on the change in surface appearance, mass loss and ultimate tensile properties of the stretch denim fabric in different directions (warp, weft and biased).Design/methodology/approachAfter abrading the fabrics in three different directions (warp, weft and biased), the loss in ultimate tensile properties, mass loss and surface appearance has been investigated in the respective directions of abrasion (warp, weft and biased). The study also encompasses the effect of different types of stretch yarn with varying levels of elastane content on such unidirectional abrasive damage.FindingsIt is seen that with the same level of abrasion cycles, the fabric's response in terms of mass loss and loss in ultimate tensile properties are different in different directions. The mass loss due to abrasion in biased direction is found to be minimum. The loss in ultimate tensile properties due to abrasion was highest in the weft direction. It is also found that the higher mass loss due to abrasion does not always result in a greater loss in ultimate tensile properties. The composition and the structure of the weft yarn significantly affected the extent of the mass loss and the loss in ultimate tensile properties during abrasive damage.Originality/valueThe impact of abrasive damage in terms of mass loss and loss in tensile strength along the different directions of denim fabric has not been explored till date. Abrasion of fabric can be done both in multi-direction (Lissajous motion) as well as in uni-direction (linear motion). The multidirectional abrasion provides a holistic or comprehensive idea of the fabric's response to the abrasive damage but does not take into consideration the fabric's anisotropic response to the abrasive damage. Most of the earlier investigation related to abrasive damage of denim fabric has been done in instruments where the motion of the abrader is multidirectional (Lissajous) in nature. For greater depth of understanding about the fabric performance under abrasive damage along the various direction (warp, weft and biased), unidirectional abrasion is conducted in this study.

Authors: Nasir Nida Hanifah , Lestari Fatma , Kadir Abdul 
Published: May 2022

PurposeThe aim of this study is to develop and redesign the Mobile Panic Button UI (PB1) application as an emergency notification service, as well as conduct a simulation on the use of the new version of the application.Design/methodology/approachThis study used the operational research design with a theoretical research framework that followed input, process and output. Primary data were collected through observation, measurement and interview while the secondary data were obtained from literature review. The first step of the analysis was input analysis that included problem identification on the existing Panic Button as input, or PB 1 in this study. This was followed by the analysis of the planned second version of the Panic Button (PB2) development, starting from problem identification to trial and error testing and evaluation of the results of the simulation of seven types of emergency events that involved users, emergency response officers and experts.FindingsThe study shows that the first version of PB1, developed in and used since 2017 at Universitas Indonesia, still had several weaknesses, particularly in its inability to provide adequate information. Only 30% of the standards for a mobile emergency application were met by PB1, which affected the performance of emergency responses. This was one of the reasons why the new version of Panic Button UI (PB2) was developed. The new features in PB2 comprise the inclusion of features for collecting information on user's name and mobile phone number, emergency category options, victim information, photo/voice information, description on the nature of the emergency (text), location selection, emergency notification delivery, notification delivery popup and emergency notification delivery to the emergency response team (ERT) officer. The time needed for using the second version of the Panic Button UI mobile application is 20 s faster than the previous one. PB2 can accelerate response time and response action time; improve response accuracy; facilitate the emergency notification process; and facilitate emergency communication.Originality/valueVarious notification alert systems have been developed in many countries. However, there is a lack of information in Indonesia, especially in educational setting. This study is the first study on a notification alert system application applied in the university. Emergency response is critical due to the big impact of disasters. This study will inform the stakeholders or users, particularly those in educational institution on how to implement mobile app–based emergency response notification systems.

Published: May 2022

PurposeSocial initiatives must disclose their results to access support. However, there is no theoretical consensus about how to do it. It is still necessary to understand the value creation in social initiatives because they may or not have economic goals. However, these goals serve to make the social ones feasible. This study aims to cut this Gordian knot by providing measures aligned to the value theory but developed by the social lens. It offers a non-economic-focused approach to dealing with assessment complexity and with multiple stakeholders’ needs for information.Design/methodology/approachA consolidation research path is suggested by three composed measures built upon tested and reliable scales. These value measures are discussed through narratives from Portuguese investors and social entrepreneurs in a mixed-methods design. Content analysis and online survey provided data for descriptive statistics, exploratory factor analysis and Cronbach's alpha test.FindingsThe analyses supported the value measures. Thus, they allow an effective way to assess and report the social value created. It also highlighted a potential use in preventive and corrective approaches helpful for several organizations that pursue social goals.Research limitations/implicationsThe measures were tested based on social entrepreneurs' opinions. Future studies can include beneficiaries' opinions, allowing comparisons that can help to set more realistic goals and better investment criteria.Originality/valueThe relationship between investors and initiatives can improve, boosting their impact on society. The measures can highlight prioritization choices that influence the way value is created. Hence, they serve as a sensemaking from a holistic standpoint.

Authors: Garg Harish , Thanh Dang Ngoc Hoang , Rizk-Allah Rizk M. 
Published: May 2022

PurposeThe paper aims to introduce a novel concept to solve the bi-level multi-criteria nonlinear fractional programming (BL-MCNFP) problems. Bi-level programming problem (BLPP) is rigorously flourished and studied by several researchers, which deals with decentralized decisions by comprising a sequence of two optimization problems, namely upper and lower-level problems. However, on the other hand, many real-world decision-making problems involve multiple objectives with fraction aspects, called fractional programming problems that reflect technical and economic performance.Design/methodology/approachThis paper introduces a VIKOR (“VlseKriterijumska Optimizacija I Kompromisno Resenje”) approach to solve the BL-MCNFP problem. In this approach, an aggregating function based on LP metrics is formulated on the basis of the “closeness” scheme from the “ideal” solution. The three steps perform the solution process: First, a new concept is attempted to minimize and maximize of the numerators and denominators from their respective ideal solutions and anti-ideal values simultaneously. Second, for each level, the K-dimensional objective space of each level is converted to a one-dimensional space by an aggregating function. Third, to obtain the final solution, all levels are combined into single-level model where the decision variables of upper levels are interrelated with other levels through fuzzy strategy-based linear and nonlinear membership functions.FindingsThe effectiveness of the proposed VIKOR is demonstrated by numerical examples, where the reported results affirm that the extended VIKOR method provides superior results in comparison with the same methods in the literature, and it is a good alternative to BL-MCNFP problems.Originality/valueIn terms of the assistance-based right decision, a parametric analysis for the weight of the majority is provided to exhibit a wide range of compromise solutions for the decision-maker.

Team knowledge management: how leaders’ expertise recognition influences expertise utilization
Authors: Ye Suyang , Zhao Teng 
Published: May 2022

PurposeThis paper aims to extend the literature on how to harness the expertise of team members. This paper suggests that the leader’s expertise recognition plays an important role in enhancing team effectiveness. In addition, leader’s personal dispositions shape how the leader’s recognition could benefit team expertise utilization.Design/methodology/approachThis paper utilizes a two-wave, multi-source (team leaders and team members rated) survey design from 78 information technology teams to test the proposed moderated mediation model.FindingsThe data analysis revealed that a leader’s expertise recognition is positively related to team expertise utilization. Moreover, the leaders’ traits (i.e. social dominance and reflectiveness) act as important boundary conditions of this relationship. Specifically, only when the leader is less socially dominant or more reflective can they fully utilize the expertise recognition and enhance team creativity through team expertise utilization.Originality/valueThis study investigated an important issue that expertise utilization research has hitherto overlooked: the effects of leader’s expertise recognition on team expertise utilization and team creativity.

Published: May 2022

PurposeThis paper seeks to analyze the concept of packaging re-design with the main purpose to better exploit the utilized space within a secondary packaging, pallet and/or to make better use of transport, respectively. In addition, it investigates and discusses the importance of space exploitation in relation to environmental benefits, the industry and the community in general.Design/methodology/approachThe research is based on a specific case study, in which two different options of a bottle with the same capacity are investigated in terms of: shape and space utilization. The investigation includes a detailed numerical comparison between the bottles, in order to show the strengths and weaknesses of each option.FindingsThe analysis provides evidence that any shape improvements could result into benefits such as: reduce waste, increase space utilization and increase the number of transported products per load. This in turn could reduce the energy and CO2 emissions required per unit of product carried or stored. The analysis shows that a better utilization of the space could further offer significant economic benefits for the company with respect to transportation and warehousing.Research limitations/implicationsHowever, the proposed packaging design solutions are proposed with the guarantee that the protection of the product is ensured, the logistics activities are facilitated as expected, the needs of the user are fully covered and the cost is maintained low. This solution, therefore, addresses the economic, social and environmental aspect of packaging.Originality/valueThis paper fulfills an identified need to study the relation between the packaging redesign concept and the various environmental and economic benefits for the industry and the participants of the supply chain, while maintaining the needs of the user. This works contributes to other more recent studies that are concerned with packaging design innovation that respond to key environmental concerns.

AbstractRegular endurance exercise is a non‐pharmacological strategy to protect the liver against diseases. Conversely, exercise may be harmful when excessive, the so‐called overtraining. As expected, mice who underwent an overtraining protocol presented higher levels of proinflammatory cytokines in the serum and liver. Based on the relationship among overtraining, inflammation and mammalian target of rapamycin complex 1 (mTORC1) upregulation, the present study verified if animals submitted to an overtraining protocol, but with inhibition of the mTOR pathway via rapamycin injections could mitigate the liver and serum inflammation. Once autophagy can be linked to the improvement of hepatic dysfunction, we also investigated if the inhibition of mTORC1 by rapamycin can improve hepatic autophagy. The animals were randomized into four groups: control (CT; sedentary mice), overtraining by downhill running (OT; mice submitted to the downhill running‐based overtraining protocol), overtraining by downhill running with chronic administration of rapamycin (OT/Rapa; mice submitted to the downhill running‐based overtraining protocol with intraperitoneal injections of rapamycin) and aerobic (AER; submitted to aerobic training protocol). The serum and liver of the animals were used for biochemical analysis, reverse transcription‐quantitative polymerase chain reaction (RT‐qPCR) and immunoblotting. The main results are (a) OT and OT/Rapa protocols decreased the performance; (b) the protein levels of interleukin 6 (IL‐6) were higher for the OT group; the OT/Rapa group reduced the autophagic genes, increased the microtubule‐associated protein light chain 3 II/I (LC3II/LC3I) protein ratio and decreased the sequestosome 1 (SQSTM1) protein. In conclusion, rapamycin appears efficiently to increase the autophagy proteins and decrease IL‐6 protein in the liver of overtraining mice.
Zingerone stimulates osteoblast differentiation by increasing Smad1/5/9‐mediated HO‐1 expression in MC3T3‐E1 cells and primary mouse calvarial cells
Authors: Kim A‐Rang , Lim Young‐Ju , Jang Won‐Gu 
Published: May 2022

AbstractZingerone is a non‐volatile compound found mainly in dried ginger. Zingerone increases the expression of osteogenic markers and has antioxidant effects. A previous study showed that zingerone accelerated osteoblast differentiation by suppressing the expression of Smad7, a member of the inhibitory Smad (I‐Smad) family. However, it is not known if zingerone can induce osteoblast differentiation by regulating Smad1/5/9, a member of the receptor‐regulated Smad (R‐Smad) family. In addition, osteoblast differentiation induced by Smad1/5/9 mediated increases in the expression of heme oxygenase 1 (HO‐1) has not been reported. This study investigated the effects of zingerone on osteoblast differentiation and confirmed the relationship between Smad1/5/9 and HO‐1. Zingerone increased the expression of osteogenic genes including runt‐related transcription factor 2 (Runx2), distal‐less homeobox (Dlx5) and osteocalcin (OC) and also promoted Smad1/5/9 phosphorylation. Interestingly, HO‐1 expression was also elevated by zingerone, and an inhibitor of HO‐1 (Sn[IV] protoporphyrin IX dichloride [SnPP]) suppressed the zingerone‐induced increase in HO‐1 expression and expression of osteogenic marker genes such as Dlx5, Runx2 and OC. Protein phosphatase 2A Cα (PP2A Cα, an inhibitor of Smad1/5/9) suppressed the zingerone‐induced increase in HO‐1 expression and expression of osteogenic marker genes. The zingerone‐induced increase in HO‐1 luciferase activity was suppressed by PP2A Cα. Taken together; our data demonstrate that zingerone promotes osteoblast differentiation by increasing Smad1/5/9 mediated HO‐1 expression.
