In this study, users’ acceptance of an on-bike system that warns about potential collisions with motorized vehicles as well as its influence on cyclists’ behavior was evaluated. Twenty-five participants took part in a field study that consisted of three different experimental tasks. All participants also completed a follow-up questionnaire at the completion of the three-task series to elicit information about the acceptance of the on-bike system. In the experiment phase, participants were asked to ride the bicycle throughout a circuit and to interact with a car at an intersection. Participants completed three laps of the circuit. The first lap involved no interaction with the car and served the purpose of habituation. In the second and third laps participants experienced a conflict with an incoming car at an intersection. In the second lap, the on-bike device was not activated, while in the third lap, participants received a warning message signaling the imminent conflict with the car. We compared the difference in user’s behavior between the second lap (conflict with a car without the warning of the on-bike system) and the third lap (conflict with a car with the warning of the on-bike system). Results showed that, when entering the crossroad, participants were more likely to decrease their speed in case of warning of the on-bike system. Further, the on-bike system was relatively well accepted by the participants. In particular, participants did not report negative emotions when using the system, while they trusted it and believed that using such technology would be free from effort. Participants were willing to spend on average 57.83€ for the system. This study highlights the potential of the on-bike system for promoting bicycle safety.

Introduction: In terms of access to treatment of acromioclavicular joint injuries, there are many controversies, especially after the appearance of works that promote "neglecting of injury". Goal: The aim of this paper is to give a comparative analysis of the results of rehabilitation of patients after acute injury of the acromioclavicular joint of the third degree, treated by two surgical techniques: by Phemister and Vukov. Material and methods: In this study, we investigated a total of 60 operated patients: 30 patients were operated by Phemister technique, and 30 by Vukov technique. Results: Postoperative follow-up lasted for one year. Between these two groups, the time when the rehabilitation process began is significantly different p<0.01. With technique by Vukov, the rehabilitation begins on the first postoperative day and with technique by Phemister it begins later (after 7 weeks outpatient). With technique by Phemister, rehabilitation lasted on average 60 days, and with technique by Vukov on average 40 days. The duration of recovery is also significantly different p< 0.01, with technique by Vukov the duration time is shorter, and therefore the process of rehabilitation in days - is shorter than with the other technique. Both techniques gave good stability of the lateral end of clavicle. The difference was not statistically significant p> 0.05, which means that both techniques can be applied depending on the indication and the experience of the surgeon.

SUMMARY OBJECTIVE: To investigate clinical curative effects of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training on chronic nonspecific lower back pain. METHODS: A total of 60 patients with chronic nonspecific lower back pain in the Outpatient Department were included in this study. These patients were randomly divided into two groups: the observation group and the control group. The control group adopted a single sling-exercise-therapy training three times a week, while the observation group adopted lumbar oblique-pulling manipulation in combination with manipulation treatment once a week. The course of treatment lasted for four weeks. RESULTS: (1) Before and after treatment, the ODI score was compared within the group. A remarkable statistical significance was observed from the third day (P<0.05). At the third month of follow-up, the difference in ODI scores between these two groups was statistically significant (P<0.05). (2) Before and after treatment, it was observed that differences in VAS scores from the third day were statistically significant (P<0.05). (3) The difference in muscle strength between these two groups had remarkable statistical significance in the third month of follow-up (P<0.05). CONCLUSION: The effective rehabilitation function of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training in patients with CNLBP is superior to that of sling-exercise-therapy training alone.

Purpose: Children's narratives may differ based on whether they are describing events that elicit positive versus negative emotions and may be more detailed when talking about negative emotions. Understanding how children retell stories representing varied emotions may guide educators in providing opportunities for children to develop social communication. This study examined retells of stories depicting positive versus negative emotions and responses to follow-up questions relating to facets of social communication. Method: Video stories depicting positive versus negative emotions were presented to 22 preschool children (ages 4;1–5;3 [years;months]). Macrostructure in the retells (measured by the Index of Narrative Complexity) and talk about emotions (measured by number and variety of emotion words) and action/attempts (rated by a rubric for quality of response) were analyzed. Results: The only significant result was the difference between the number of times the macro element, complication, was included in retells, with a greater number in the negative condition. Conclusion: The consistent quality of retells across emotion valence suggests that positive and negative emotions may both be used in fictional stories depicting social scenarios to develop opportunities to assess and talk about facets of social communication.

This study compared the risk of chronic periodontitis (CP) between chronic rhinosinusitis (CRS) and non-chronic rhinosinusitis (control) patients using a national cohort dataset from the Korean Health Insurance Review and Assessment Service. CRS (n = 5951) and control participants (n = 23,804) were selected after 1:4 ratio matching for age, sex, income, region of residence, and preoperative CP visits. Postoperative CP visits were measured between 2002 and 2015. The margin of equivalence of the difference between the CRS and control groups was set between −0.5 and 0.5. Statistical significance was noted in the post-index date (ID) of the third, fourth, and fifth year periods. In subgroup analyses according to age and sex, statistical significance was observed in 40–59-year-old males in post-ID third, fourth, and fifth year periods, ≥60-year-old males in post-ID third and fourth year periods, and ≥60-year-old females in post-ID fifth year period (p < 0.05, each). In another subgroup analysis based on the number of pre-ID CP visits, statistical significance was observed for pre-ID CP (0 time) in the third, fourth, and fifth year periods (p < 0.05, each). This study revealed that CRS participants were likely to receive CP diagnosis and treatment.

Abstract. Background: Monitoring of suicide rates in the recovery phase following a devastating disaster has been limited. Aim: We report on a 7-year follow-up of the suicide rates in the area affected by the Great East Japan Earthquake, which occurred in March 2011. Method: This descriptive study covered the period from March 2009 to February 2018. Period analysis was used to divide the 108-month study period into nine segments, in which suicide rates were compared with national averages using Poisson distribution. Results: Male suicide rates in the affected area from March 2013 to February 2014 increased to a level higher than the national average. After subsequently dropping, the male rates from March 2016 to February 2018 re-increased and showed a greater difference compared with the national averages. The difference became significant in the period from March 2017 to February 2018 ( p = .047). Limitations: Specific reasons for increasing the rates in the recovery phase were not determined. Conclusion: The termination of the provision of free temporary housing might be influential in this context. Provision of temporary housing was terminated from 2016, which increased economic hardship among needy evacuees. Furthermore, disruption of the social connectedness in the temporary housing may have had an influence. Our findings suggest the necessity of suicide rate monitoring even in the recovery phase.

The reality of the difference in applying Islamic law in the context of marriage law legislation in modern Muslim countries is undeniable. Tunisia and Turkey, for example, have practiced Islamic law of liberal nuance. Unlike the case with Saudi Arabia and the United Arab Emirates that still use the application of Islamic law as it is in their fiqh books. In between these two currents many countries are trying to apply the law in their own countries by trying to bridge the urgent new needs and local wisdom. This is widely embraced by modern Muslim countries in general. This paper reviews typologically the heterogeneousness of family law legislation of modern Muslim countries while responding to modernization issues. Typical buildings seen from modern family law reforms can be classified into four types. The first type is progressive, pluralistic and extradoctrinal reform, such as in Turkey and Tunisia. The second type is adaptive, unified and intradoctrinal reform, as in Indonesia, Malaysia, Morocco, Algeria and Pakistan. The third type is adaptive, unified and intradoctrinal reform, represented by Iraq. While the fourth type is progressive, unifiied and extradoctrinal reform, which can be represented by Somalia and Algeria.

The object of the study of the knowledge of the variety of the Quranic reading  is the  Qur'an itself. The focus is on the difference of the reading and its articulation. The method is based on the riwayat or narration which is originated from the Prophet (Rasulullah saw) and its use is to be one of the instruments to keep the originality of the Qur’an. The validity of the reading the Qur’an is to be judged based on the valid chain  (sanad ¡a¥ī¥)  in accord with the Rasm U£mānÄ« as well as with the  Arabic grammar. Whereas the qualification of its originality is divided into six stages as follow: the first is mutawātir, the second is masyhÅ«r, the third is āhād, the fourth is syaz, the fifth is maudū‘, and the six is mudraj. Of this six catagories, the readings which can be included in the catagory of mutawātir are Qiraat Sab‘ah (the seven readings) and Qiraat ‘Asyrah  (the ten readings). To study this knowledge of reading the Qur’an (ilmu qiraat), one is advised to know about special terms being used such as  qiraat  (readings), riwayat (narration), tarÄ«q (the way), wajh (aspect), mÄ«m jama‘, sukÅ«n mÄ«m jama‘ and many others.

This book aims to answer the following questions: what is the difference between a cause and a background condition? What is it to manifest a disposition? Can dispositions be extrinsic? What is the most basic kind of causation? And, what might a structural explanation be? Each chapter takes up a subset of these questions; the chapters are written to be readable independently. The answers defended rely on three ideas. Two of those ideas use a distinction from the study of lexical aspect, namely the distinction between stative verbs and non-stative verbs. The first idea is that events go with non-stative verbs, in the sense that “If S, then an event occurred in virtue of the fact that S” is true when the main verb in the clause going in for “S” is non-stative. The second is that acting, doing something, goes with non-stative verbs, in the sense that “In Ving X did something” is true iff V is a non-stative verb. The third idea is about levels of explanation: “(A because B) because C” does not entail “A because C.”

This chapter presents three different perspectives on centrality. In part, the motivation is definitional: what counts as a centrality measure and what doesn’t? But the primary purpose is to lay out ways that centrality measures are similar and dissimilar and point to appropriate ways of interpreting different measures. The first perspective the chapter considers is the “walk structure participation” perspective. In this perspective, centrality measures indicate the extent and manner in which a node participates in the walk structure of a graph. A typology is presented that distinguishes measures based on dimensions such as (1) what kinds of walks are considered (e.g., geodesics, paths, trails, or unrestricted walks) and (2) whether the number of walks is counted or the length of walks is assessed, or both. The second perspective the chapter presents is the “induced centrality” perspective, which views a node’s centrality as its contribution to a specific graph invariant—typically some measure of the cohesiveness of the network. Induced centralities are computed by calculating the graph invariant, removing the node in question, and recalculating the graph invariant. The difference is the node’s centrality. The third perspective is the “flow outcomes” perspective. Here the chapter views centralities as estimators of node outcomes in some kind of propagation process. Generic node outcomes include how often a bit of something propagating passes through a node and the time until first arrival of something flowing. The latter perspective leads us to consider the merits of developing custom measures for different research settings versus using off-the-shelf measures that were not necessarily designed for the current purpose.
