Gait analysis is an area within biomechanics that quantifies the motion of an animal. The most common motion analysis method uses cameras to track the position of markers on bodily surfaces over time. Although each species has a common skeletal frame to reference recorded motions, the soft tissue covering each is not rigid. Markers, therefore, experience motion relative to the bone and do not accurately portray underlying bone activity. This limits clinical use of motion studies and the understanding of joint motion.

This paper aims to find out how non-Muslim countries such as Japan and Germany develop the halal tourism industry and highlight the narratives of halal tourism in both non-Muslim countries. This study has been done qualitatively in focus on the literature review and discourse analysis method as the main approach. Over time, the halal label has been led to be an inseparable aspect of lifestyle segment in certain society. It did not occur only in the food industry, but also been penetrated into various other industries, one of those is known as halal tourism. According to Global Muslim Tourist Index (GMTI), this phenomenon is not only the Muslim countries Phenomenon, but also increase in the non-Muslim countries. The halal tourism business is expanding and start to be the main economical income by Muslim minority countries, including Japan and Germany. The presence of these two countries in developing halal tourism is unique, because it is not a country with a Muslim majority, but it is precisely the target of foreign Muslim tourists, including Indonesians. Although Indonesia has been named the best halal destination according to GMTI, in fact the interest in halal tourism developed by Japan and Germany is far more promising. No doubt this has become a challenge for Indonesia to enter the this global market competition. Therefore, compared to following the market trend with profit oriented, Indonesia as a Muslim-majority country should deliver halal tourism towards the target of justice and welfare of the people.Tulisan ini bertujuan untuk memahami wacana dan kepentingan yang mengiringi perkembangan wisata halal di Jepang dan Jerman, sebagai negara non-muslim. Hal ini dikarenakan, meskipun berstatus negara non-muslim, keduanya mengalami peningkatan yang cukup signifikan dalam hal pengembangan dan tingkat kedatangan turis muslim. Dengan menggunakan pendekatan teori hegemoni oleh Laclau dan Mouffe yang menekankan pada aspek logic of difference dan chain of equivalent sebagai kunci utama internalisasi wacana hegemonik, tulisan ini dimaksudkan untuk melihat beragam wacana dan kepentingan mengiringi perkembangan wisata halal, baik yang tersirat maupun tersurat. Untuk mancapai tujuan tersebut, metode pengumpulan data akan dilakukan dengan studi kepustakaan yang fokus pada beragam artikel, berita, serta laporan-laporan terkait perkembangan industri pariwisata halal di Jepang dan Jerman. Dari berbagai data dan analisa, tampak jelas bahwa meskipun ada beragam wacana dan kepentingan, perbedaan tersebut berada dalam wacana besar neoliberalisme. Sehingga, wisata halal di negara non-muslim dapat dipahami sebagai sebuah wacana hegemonik yang hanya menguntungkan negara dan pasar tetapi mengesampingkan masyarakat. Dengan belajar dari temuan tersebut, Indonesia sebagai negara dengan populasi muslim terbesar diharapkan mampu mengembangkan industri wisata halal yang ramah, bukan hanya kepada turis dan pemodal, melainkan juga pada masyarakat sebagai garda terdepan industri wisata halal.

Denticles are small, tooth-like protrusions that are commonly found on the palate of early tetrapods. Despite their widespread taxonomic occurrence and similar external morphology to marginal teeth, it has not been rigorously tested whether denticles are structurally homologous to true teeth with features such as a pulp cavity, dentine, and enamel, or if they are bony, tooth-like protrusions. Additionally, the denticles are known to occur not only on the palatal bones but also on a mosaic of small palatal plates that is thought to have covered the interpterygoid vacuities of temnospondyls through implantation in a soft tissue covering; however, these plates have never been examined beyond a simple description of their position and external morphology. Accordingly, we performed a histological analysis of these denticulate palatal plates in a dissorophoid temnospondyl in order to characterize their microanatomy and histology. The dentition on these palatal plates has been found to be homologous with true teeth on the basis of both external morphology and histological data through the identification of features such as enamel and a pulp cavity surrounded by dentine. In addition, patterns of tooth replacement and ankylosis support the hypothesis of structural homology between these tiny teeth on the palatal plates and the much larger marginal dentition. We also provide the first histological characterization of the palatal plates, including documentation of abundant Sharpey’s fibres that provide a direct line of evidence to support the hypothesis of soft tissue implantation. Finally, we conducted a survey of the literature to determine the taxonomic distribution of these plates within Temnospondyli, providing a broader context for the presence of palatal plates and illustrating the importance of maintaining consistency in nomenclature.

Corporate sustainability (CS) has many advantages such as enhancing brand value, providing reputation, and also focuses on gaining the trust of stakeholders. This is a qualitative exploratory study; its goal is to understand how CS research has changed over time. The most cited articles were selected from the journals indexed in SSCI (2000-2019). One hundred and two articles were selected and analyzed by content analysis method. Nature of typical samples, major themes, and research methods used were sought to investigate in CS research. Results showed that there was some scarcity in studies choosing a particular country as a sample. There were no articles in areas important for sustainability research. Besides, index types are barely used in articles. Some subject areas have attracted attention for years and haven't lost their popularity, but some remained in the background. The most used method was content analysis.

Abstract Data from N = 111 centenarians (M = 100.88; SD = 1.48) residing in Oklahoma was used to examine patterns in the relationship between the God oriented vs. non-God oriented longevity secrets and subjective well-being. Observational Oriented Modeling (OOM) was then used to conduct an ordinal analysis using concatenated ordering to produce degree of fitness between data and underlying patterns in life satisfaction and purpose-in-life across three time points. OOM is a data analysis method used to evaluate fitness of proposed patterns to data called PCC. Results indicated that centenarians maintaining a God-oriented longevity secret fit a decreased pattern in life satisfaction (PCC = 25.00, c-value = .09); whereas centenarians not maintaining a God-oriented longevity secret fit the same pattern (PCC = 49.18, c-value = .06). Meanwhile, centenarians having a God-oriented longevity secret fit a decreased pattern of purpose-in-life (PCC = 71.43, c-value =.12); whereas centenarians having a non-God oriented longevity secret fit the same pattern (PCC = 53.45, c-value = .28). In comparison to centenarians who acknowledged something other than God as the secret to their longevity, those who cite God as the reason for longevity tend to proportionately maintain a more satisfying view of life, yet experience a deteriorating sense of purpose over time. Results indicate that longevity secrets reflect divergent patterns in subjective well-being among persons living beyond 100 years. This has implications relative to how geriatric practitioners design interventions, services, or programs to enhance quality-of-life for long-lived adults.

Interface stresses and stump shape were measured during sessions over a twomonth interval on a transtibial amputee subject. Results from thirteen transducer sites monitored during four sessions showed greater interface pressure changes over time at anterior sites than at lateral or posterior locations. There was a trend of decreased pressure with stump swelling and increased pressure for stump atrophy. During one session in which stump shape was monitored over a 23.1 min interval after ambulation, stump swelling was localised. Swelling tended to increase in the regions of initial enlargement, as opposed to redistributing through different areas over time. Regions of swelling were anterior lateral and posterior proximal, areas of thick underlying soft tissue. Identification of localised areas of swelling and atrophy and understanding of their effects on interface pressures could be used to improve individual socket design.

Joint motion simulators (JMS’s) have been developed for many applications enabling the repeatable testing of prostheses, scientific investigations of joint mechanics and the study of surgical procedures.[1–4] Although Morrey has reported that radial head implants have lower post-operative satisfaction than other joint implants[5] and Dunning has examined several issues with radial heads, many problems remain.[6] It is therefore beneficial to develop a simulator capable of evaluating radial head implants. A robust simulator can also provide the ability to test soft tissue strains at the elbow and compare control schemes that may elucidate the body’s means of controlling multiaxial multimuscle systems.

Abstract Funding Acknowledgements Philips BACKGROUND Developing new training tools for TransThoracic Echocardiography (TTE) is more important than ever, as the use of ultrasound expands with the advent of mobile devices, both reducing costs and increasing the number of sites and operators. Two major challenges are the lack of experts to meet the growing demand for training and the risk of unnecessary examinations and misdiagnosis by users who lack proper training. PURPOSE To evaluate Artificial Intelligence (AI)-assisted TTE for assessing and improving novices" echocardiography skills. METHODS AI-assisted TTE relies on real-time analysis of the ultrasound stream by AI algorithms (e.g. for automated view recognition) to provide adaptive feedback to the user. It was compared to standard TTE in a prospective study including 40 medical students with no prior ultrasound experience ("novices") and 40 healthy volunteers of varying echogenicity. Novices received a standardized 10-minute presentation of the basic machine controls and requirements of an apical 4-chamber (AP4) acquisition. They were then asked to perform three consecutive AP4 acquisitions on a randomly assigned healthy volunteer: 1) "initial" standard TTE, 2) AI-assisted TTE and 3) "repetition" standard TTE, with a maximum of 3 minutes per acquisition. Additionally, for reference purposes, an AP4 acquisition was performed by an expert. Both the performance over time and the final acquisition performance were assessed by an AI-based AP4 quality score and expressed relatively to the reference score. The suitability for clinical use was assessed by an expert on a 0-3 semi-quantitative scale. RESULTS Kaplan-Meier analysis of the probability to match reference performance over time (see left part in figure below) validated the positive and significant contribution of AI-assisted TTE wrt initial TTE (median time = 16.1s vs. 45.7s, p = 0.026). There was also a positive, though non-significant, contribution wrt repetition TTE (median time = 25.7s, p = 0.20), while the difference between standard TTEs was non-significant (p = 0.24). A majority of novices (70%, resp. 72.5%) improved their final acquisition with AI-assisted TTE wrt initial TTE, resp. repetition TTE. The final performance gain (81.7 ± 29.7% vs. 60.8 ± 40.4%, resp. 70.4 ± 33.9%, see right part in figure below) was shown to be significant by Wilcoxon matched-pair signed-rank test (p < 0.001, resp. p = 0.003). There was no significant difference between standard TTEs (p = 0.34). AI-assisted TTE was also associated with improved suitability for clinical use (2.53 ± 0.79 vs. 2.00 ± 1.03, resp. 2.08 ± 0.98). Among these acquisitions, 50% were found fully suitable for clinical use (vs. 22.5%, resp. 27.5%). CONCLUSION AI-assisted TTE can assess and improve novices" echocardiography skills. Developing and embedding AI-assistance in ultrasound devices could be a cost-effective way to support the training of novices and key to acquisition standardization. Abstract 541 Figure.

The aim of this study was to evaluate the microscopic structure of soft tissue covering titanium plates and screws used in jaw surgery (mandible fracture and orthognathic surgery), after a minimum period of 12 months from insertion, and to quantify the presence of any metallic particles. Periosteum covering the osteosynthesis plates was removed from 20 patients and examined by light microscopy in order to assess the cell morphological changes and the possibility of metal particles presence in the soft tissue. Local signs of tissue toxicity or inflammation were taken into consideration when evaluating the routine removal of titanium maxillofacial miniplates. No signs of screw loosening or acute inflammation were detected on the osteosynthesis site, but de-coloration of the periosteum was seen, and metallic particles were observed to have migrated into the soft tissues. Even if the titanium is well-tolerated by the human body in time, without severe local or general complications, our findings suggest that plate removal should be considered after bone healing has occurred.
