Published: October 2023

AimsThe aim of this study was to investigate the agreement in interpretation of the quality of the paediatric hip ultrasound examination, the reliability of geometric and morphological assessment, and the relationship between these measurements.MethodsFour investigators evaluated 60 hip ultrasounds and assessed their quality based the standard plane of Graf et al. They measured geometric parameters, described the morphology of the hip, and assigned the Graf grade of dysplasia. They analyzed one self-selected image and one randomly selected image from the ultrasound series, and repeated the process four weeks later. The intra- and interobserver agreement, and correlations between various parameters were analyzed.ResultsIn the assessment of quality, there a was moderate to substantial intraobserver agreement for each element investigated, but interobserver agreement was poor. Morphological features showed weak to moderate agreement across all parameters but improved to significant when responses were reduced. The geometric measurements showed nearly perfect agreement, and the relationship between them and the morphological features showed a dose response across all parameters with moderate to substantial correlations. There were strong correlations between geometric measurements. The Graf classification showed a fair to moderate interobserver agreement, and moderate to substantial intraobserver agreement.ConclusionThis investigation into the reliability of the interpretation of hip ultrasound scans identified the difficulties in defining what is a high-quality ultrasound. We confirmed that geometric measurements are reliably interpreted and may be useful as a further measurement of quality. Morphological features are generally poorly interpreted, but a simpler binary classification considerably improves agreement. As there is a clear dose response relationship between geometric and morphological measurements, the importance of morphology in the diagnosis of hip dysplasia should be questioned.Cite this article: Bone Joint J 2023;105-B(10):1123–1130.

AimsThe primary aim of this trial was to compare the subsidence of two similar hydroxyapatite-coated titanium femoral components from different manufacturers. Secondary aims were to compare rotational migration (anteversion/retroversion and varus/valgus tilt) and patient-reported outcome measures between both femoral components.MethodsPatients were randomized to receive one of the two femoral components (Avenir or Corail) during their primary total hip arthroplasty between August 2018 and September 2020. Radiostereometric analysis examinations at six, 12, and 24 months were used to assess the migration of each implanted femoral component compared to a baseline assessment. Patient-reported outcome measures were also recorded for these same timepoints. Overall, 50 patients were enrolled (62% male (n = 31), with a mean age of 65.7 years (SD 7.3), and mean BMI of 30.2 kg/m2 (SD 5.2)).ResultsThe two-year subsidence was similar for Avenir (-0.018 mm (95% confidence interval (CI) -0.053 to 0.018) and Corail (0.000 mm (95% CI -0.027 to 0.026; p = 0.428). Both anteversion/retroversion (Avenir 0.139° (95% CI -0.204 to 0.481°); Corail -0.196° (95% CI -0.445 to 0.053°; p = 0.110) and varus/valgus tilt (Avenir -0.024° (95% CI -0.077 to 0.028); Corail -0.049° (95% CI -0.098 to 0.000°; p = 0.473) were not statistically significantly different. After two years, patients reported similar improvements in EuroQol five-dimension five-level health questionnaire (Avenir 0.22 (SD 0.2); Corail 0.22 (SD 0.18); p = 0.965) and other outcomes scores. Patient satisfaction on a five-point Likert scale was also similar between both groups after two years (Avenir 1.38 (SD 0.88); Corail 1.33 (SD 0.57); p = 0.846).ConclusionThe performance of both femoral components was similar in terms of stability and patient outcomes.Cite this article: Bone Joint J 2023;105-B(10):1045–1051.

Abstract. Yurasbe NQ, Din NA, Palaniveloo K, Manikam S, Nagappan T. 2023. Phytochemical diversity and biological activities of Curcuma species from the East Coast of Peninsular Malaysia. Biodiversitas 24: 4243-4252. Zingiberaceae has been associated with traditional medicine for centuries. The genus Curcuma is traditionally famous and economically important for its therapeutic and nutritional values. Over 50 genera of 1600 species are recorded worldwide, with the highest concentration in the Malesian region, including Indonesia, Borneo, Thailand, Malaysia, Vietnam, Cambodia, Myanmar, and the Philippines. We investigated the methanolic crude extracts of Curcuma aeruginosa, Curcuma caesia, Curcuma longa, Curcuma xanthorrhiza, and Curcuma zedoaria from Terengganu for their phytochemicals, total phenolic content (TPC) using Folin-Ciocalteu colorimetric method, total flavonoid content (TFC) using aluminum chloride colorimetric method, antioxidant activity using the 2,2-diphenyl-1-picryl-hydrezyl (DPPH) radical scavenging activity and toxicity using brine shrimp lethality test (BSLT). Phytochemical screening revealed alkaloids, flavonoids, phenolics, saponins, tannins, triterpenoids, glycosides, lignins, and oils in all species investigated. Curcuma longa extract had the highest phenolic and flavonoid content with the value of 155.31±1.78 mg GAE/g and 151±8.35 mg quercetin/g, respectively as well as best antioxidative potential with IC50 value of 88.65±0.6 mg/mL, followed by C. zedoaria (98.61±5.23 mg/mL), C. aeruginosa (142.51±3.29 mg/mL), C. xanthorrhiza (150.01±0.63 mg/mL) and C. caesia (156.4±0.67 mg/mL). Curcuma caesia displays the lowest degree of toxicity compared to the other species, with the LC50 value of 11585 mg/mL) considered non-cytotoxic. Hence, the selected Curcuma species has potential therapeutic value to be developed into pharmaceutical due to its significant bioactive potentials and potent antioxidant capacity.

Abstract. Thawarorit A, Dermail A, Lertrat K, Chankaew S, Suriharn K. 2023. Stratified haploid identification system through the R1-nj kernel and reduced seedling vigor in tropical maize germplasm. Biodiversitas 24: 4262-4268. Haploid identification through the R1-nj marker is commonly applied in in-vivo doubled haploid technology in maize, although misclassification issues often occur. We explored the innate properties of maternal haploids at the seedling stage to verify true haploids and to reduce false positives. There are many questions about whether reduced seedling vigor is effective for haploid verification in tropical maize backgrounds. This study aimed to evaluate the haploid induction rate of Stock6-derived F3 population inducers and to investigate the effectiveness of reduced seedling vigor at the V2/V3stage as an alternative marker to verify putative haploids. Field trials and haploid induction were conducted in the rainy season of 2021 and the dry season of 2021/22 in Khon Kaen, Thailand. Two tropical source germplasm: P789 and S7328, were included as donor females. Haploids were identified through the R1-nj marker and reduced seedling vigor. Significant reduction of haploid frequency up to 2.5% on average between the two identification methods, indicating that a considerable number of false positives could be found using reduced seedling vigor. Inducer population K11 was promising since it performed a stable ability to produce haploids over donors and seasons and had a low misclassification rate. Further breeding strategies and haploid selection schemes are discussed.

Abstract. Fahmi A, Syukur S, Chaidir Z, Melia S. 2023. Isolation and molecular characterization of probiotic from Sidamanik green tea (Camellia sinensis) fermentation. Biodiversitas 24: 4277-4288. The bioavailability of green tea catechins is reduced in the gastrointestinal tract because of its instability. Probiotics are expected to increase their bioavailability in the gastrointestinal tract.There is no any information about Sidamanik fermented green tea, either probiotics, antimicrobial activity, or probiotic species that are beneficial to health. This research aims to isolate and test the characterization of probiotics from fermented green tea. Green tea from Sidamanik Sub-district was fermented with palm sugar and forest honey with 24, 48, and 72 h variation times. The fermented green tea was tested for morphological characterization,Gram staining, catalase test, and fermentation test. Then the resistance test to bile acids and salts and the antimicrobial activitytest against three pathogenic bacteria Escherichia coli Q157:H7, Staphylococcus aureus ATCC25923, and Listeria monocytogenes CFSAN004330. Two strains were selected from this series of tests, which were identified using 16S rRNA gene sequencing from different green tea fermented at the same fermentation time. The results indicated a positive lactic acid bacteria (LAB) morphological test. The characteristics of LAB can be described as a single colony being seen with a round, smooth, yellowish-white color, and a clear zone was formed around the colony, positive Gram, negative catalase, and homofermentative. LAB strains 1.1., and 4.1 were chosen to test their antimicrobial activity because they had the best acid and salt resistance viability. Then the results of molecular identification of 16S rRNA gene found that the probiotics contained in LAB strain 1.1. was Lactobacillus plantarum Y-1 and in LAB strain 4.1 was Lacticaseibacillus paracasei HBUAS62903. This study aims to find a new product of fermented green tea that has benefits in digestive health because it contains naturally processed lactic acid bacteria, is cheaper, simpler, stable at room temperature, durable in storage, and easy to serve.

Abstract. Atikah TA, Purwanti EW. 2023. The effect of peat soil and sandy soil on the growth of Eleutherine palmifolia and arbuscular mycorrhizal diversity. Biodiversitas 24: 4373-4381. Arbuscular mycorrhizae as root symbionts is capable of inducing plant growth on marginal lands. It has the potential to be used as fertilizer or soil enhancer. Mycorrhizae are commonly found in peat soils endemic to the island of Borneo. Peat soil contains a lot of organic matter needed by mycorrhizae. The development of plant roots also influences the process of mycorrhizal colonization. Apart from functioning as fertilizer, mycorrhizae is associated with Dayak shallot (Eleutherine palmifolia Merr.; syn.: Sisyrinchium palmifolium L.) roots can also overcome fusarium wilt disease. This study aimed to explore the potential of peat soil to support the growth of E. palmifolia 's and to identify mycorrhizal colonization associated with the plant. Two soil types were used for planting E. palmifolia: peat and sand. Parameters observed were plant height, number of leaves, morphospecies and each population of arbuscular mycorrhizae. The plant growth data were tabulated and analyzed with an analysis of variance, and the population of arbuscular mycorrhizae was analyzed for the level of similarity in the structure of species. The results showed that peat soil promoted the growth of E. palmifolia better than sandy soil. The similarity value of mycorrhizal species structure was 28.7%. It means that the structure of mycorrhizal species on peat were differed that on sand media. Mycorrhizae successfully explored from sandy soil were 10 morpho-species with a population of 1.441 spores, while mycorrhizae from peat soil contained 6 morphospecies with a population of 462 spores.
Change Factors Towards Sustainability at the Example of Hospitals’ Secondary Processes

Published: October 2023

Secondary processes in hospitals are causing a major part of hospitals’ carbon footprint. At the same time, initiating change towards sustainability is more difficult in secondary processes than in other processes: Often, they are not under the complete control of hospitals and involve other actors, such as service providers or purchasing companies.
The current research aims to shed light on factors influencing change in secondary processes at the example of hospitals in Germany. Building on a framework that distinguishes change factors on a micro-, meso- and macro-level, it is analysed which aspects are positively or negatively influencing change towards more sustainability.
To this end, qualitative interviews with eleven experts from hospitals and service providers have been conducted and results have been assigned to the three levels of change. Results underline the importance of inter-organisational collaboration and the design of structures and processes to establish regular cooperation and coordination. They also show that business relationships between hospitals and service providers are rather cost-related than transformational. Sustainability offers the opportunity to modify existing roles and develop future-proof businesses.
The paper contributes to existing research by focusing on multi-organisational perspectives. On a practical level, it supports hospitals in designing their change strategies and processes jointly and in collaboration with other parties that are part of secondary processes.

Keywords: sustainable change, (inter-) organisational change, hospitals’ secondary processes
On Conspiracy Thought Models in Thinking Climate Change
Authors: Myllylä Mari , Delgado José Juan Cañas , Saariluoma Pertti 
Published: October 2023

People make mistakes in their thinking. Errors in human thinking and incorrect information contents in people’s mental representations can be found in everyday context such as in arguments about the current climate crisis. Erroneous thinking can cause false thought models such as climate change denialism and conspiracy thinking. Therefore, it is important to analyze the information contents of incorrect schemas or thought models. This can be done with an approach called content-based psychology.
In this research we analyzed 2980 public opinions posted in Finnish Social Media Platform Suomi24 to study how people think about and what kinds of illusory contents they use in constructing their representations on climate issues. We wanted to ask whether one can find illusory thinking in social media posts and to outline a typical construction of a false thought model in conspiracy thinking related to climate change. As a result, we found that conspiracy thinking can be found in online media discussions, and it is strongly associated with climate change denialism. Also, different fallacious or biased thought models have combined effects in constructing active mental representations in conspiracy thought models. Analyzing mental contents makes it possible to understand denialist and illusory thinking, but it requires further work.

A Gamified Approach to Engage Sustainable User Behavior in Product Service System Solutions
Authors: Villamil Carolina 
Published: October 2023

Product service system solutions encourage to share products, reducing manufacturing processes and increasing the product life. Therefore, this might contribute to offer more sustainable solutions to users, by considering the complete socio-ecological system, the context, the stakeholder relationship, among other aspects. Where the sustainability behavior of consumers and the data provided for new information and technology (ICT) devices are key factors in the development of solutions with a higher sustainability performance. Moreover, game elements and ICT have been used in different fields to engage users. The aim of this research is to investigate if a gamified approach motivates a substantiable behavior change in users of product service system solutions. Based on a literature review, a model is proposed and applied to a product service system case of a shared laundry facility in Sweden. The model was evaluated with experts semi-structured interviews and a survey with users of the shared laundry facility. Concluding that a gamified approach has a potential to motivate behavior change towards sustainability in product service system. In future research, the proposed model will be adapted to be tested in other product service system cases, with the purpose to improve it for its application in industry and education.

Functional Conflicts in Tourist Coastal Resort Cities with Special Spa Status in Poland. The Stakeholder Approach
Authors: WOŁEK Marcin , PRÓCHNIAK Joanna , KEMPA Jarosław 
Published: October 2023

This study aims to identify and analyse the potential conflicts of tourism, resort and residents’ functions based on coastal resort cities of the highest importance in Poland (Sopot, Ustka, Kołobrzeg, Świnoujście). Coastal health resorts are specific urban units where tourist and resort functions provided under high environmental restrictions dominate the primary urban function typically focused on social and resident matters. Coastal resort cities attract tourists heavily. Hence, such cities must deal with varied stakeholder expectations. This may lead to conflicts in sustainable urban development.
The analysis considers the stakeholder perspective regarding the occurrence of various conflicts. Different research methods have been used, including case studies and stakeholder analysis based on the salience model and classifying stakeholders into homogenous groups with the attributes assigned.
The diverse and often divergent needs of stakeholders in coastal cities require a specific approach to developing such urban units, including stakeholder relationship management. A method used for the resort stakeholder analysis is based on classical stakeholder classification proposed by Mitchel, Agle and Wood (1997).
The nature of functions performed in resort cities naturally lead to internal and developmental conflicts. However, based on an assessment of attributes assigned their evaluation across key stakeholder groups, the study results show that these conflicts occurred dormant in studied cities.
The research methods used, an approach taken, and results achieved can be successfully used by decision-makers responsible for urban development to identify and manage potential conflicts deriving from diversified expectations of urban stakeholders or conflicting urban functions.
The article is of an international character and might be used to various aspects of city management, as it combines stakeholder management approach with urban development and potential function conflicts.

In modern conditions, the development of tourism is undergoing dramatic changes under the influence of a number of exogenous and endogenous factors. For tourists, those tourist areas are becoming more and more attractive, where full-fledged conditions for recreation in a unique natural environment have been created, considering the provision of comfortable stay. Thus, one of the directions of spatial organization of tourism is formation of tourist clusters. In this scientific work, the authors consider the issues of creating tourist clusters in ecotourism centers of Kazakhstan on the example of the Zerenda resort center.
The method of cartographic taxonomy was used as the main research tool, within which taxa were identified that could form the basis of a tourist cluster in a certain geographical environment. Territorial units were included in each taxon, covering territories of the area where tourist resources are located.
As a result of the study, sections of the resort area were identified, which can be covered by a tourist cluster. It is assumed that each section of the cluster has its own specific characteristics and can act as a dominant and serve as a point of attraction for tourists.
In general, given that the clustering process is a rather lengthy and complex process, the authors assume that the creation of tourist ecotourism clusters can not only increase the attractiveness of ecocenters, but also lead to the emergence of new types of recreation, including in the field of green tourism.
Digital Innovation in Hospitality: Bridging the Gap between Concierge Services and Hotel Guests
Authors: FORMAN Norbert , UDVAROS József 
Published: October 2023

This study has a primary objective of investigating the existing gap that exists between guest interactions and hotel concierge services, with an emphasis on exploring potential solutions through software technology. To attain this goal, twenty in-depth interviews were conducted; eight conversations involved hotel concierges while twelve exchanges entailed interactions with guests. In conducting these interviews, the research aimed to gain extensive knowledge regarding challenges faced by both parties throughout their communication processes. Each interview was critically analysed to systematically identify specific issues suitable for resolution via software applications.
The classification of concierge services facilitated the proposal of technology-based enhancements, which underwent testing by a focus group comprising both guests and concierges. The main objective of this study was to meticulously assess the proposed improvements in terms of their effectiveness in bridging gaps between these two groups. According to research results, there is a direct link between employing suggested software solutions and decreasing interaction discrepancies; implying that strategic usage can considerably boost hotel hospitality through better communication and comprehension among staff members and guests alike.
The research suggests a wider implementation of technological resources in the hospitality industry as they can enhance guest experience and increase concierge efficiency. Further investigation could examine how effective these software solutions are across varying hotel environments and evaluate their lasting effects on customer contentment and hotel profits.
