Abstract Purpose This study aimed to investigate the medical care provided at the venue of the weightlifting event of the Tokyo 2020 Olympic Games. Methods We retrospectively evaluated athletes who availed of medical services at the venue during the weightlifting event of the Tokyo 2020 Olympic Games. In total, 194 athletes participated in the weightlifting competition. Injuries and illnesses were classified into cases handled without physician or cases requiring medical examination by a physician. These were tabulated for each examination location (athlete medical station, field of play [FOP], first-aid station of training floor or warm-up area). Results Throughout the event, a cumulative total of 132 people used the venue medical services. Nine athletes required medical attention at the athlete medical stations. Of these nine cases, six occurred on the training floor. In the FOP, nine athletes were examined. Two experienced light-headedness, two had knee pain, and the rest had other symptoms. No athletes wanted to undergo medical examination at the athlete medical station. 89 medical procedures were performed in the first-aid station on the training floor, including 52 tapings and 37 ice compressions, and the most frequent body part which needed treatment was the knee, followed by the fingers. At the first-aid station on the match floor, 25 medical procedures were performed, including 17 ice compressions, 5 haemostasis, and 4 tapings. The body parts that most frequently needed treatment were the fingers, knees, and lower legs. Conclusion Several athletes needed treatment; however, only a few required medical care from a physician.

AbstractIntroduction:Emergency medical services (EMS) responses to mass gatherings have been described frequently, but there are few reports describing the response to a single-day gathering of large magnitude.Objective:This report describes the EMS response to the largest single-day, ticketed concert held in North America: the 2003 “Toronto Rocks!” Rolling Stones Concert.Methods:Medical care was provided by paramedics, physicians, and nurses. Care sites included ambulances, medically equipped, all-terrain vehicles, bicycle paramedic units, first-aid tents, and a 124-bed medical facility that included a field hospital and a rehydration unit. Records from the first-aid tents, ambulances, paramedic teams, and rehydration unit were obtained. Data abstracted included patient demographics, chief complaint, time of incident, treatment, and disposition.Results:More than 450,000 people attended the concert and 1,870 sought medical care (42/10,000 attendees). No record was kept for the 665 attendees simply requesting water, sunscreen, or bandages. Of the remaining 1,205 patients, the average of the ages was 28 ±11 years, and 61% were female. Seven-hundred, ninety-five patients (66%) were cared for at one of the first-aid tents. Physicians at the tents assisted in patient management and disposition when crowds restricted ambulance movement. Common complaints included headache (321 patients; 27%), heat-related complaints (148; 12%), nausea or vomiting (91; 7.6%), musculoskeletal complaints (83; 6.9%), and breathing problems (79; 6.6%). Peak activity occurred between 14:00 and 19:00 hours, when 102 patients per hour sought medical attention. Twenty-four patients (0.5/10,000) were transferred to off-site hospitals.Conclusions:This report on the EMS response, outcomes, and role of the physicians at a large single-day mass gathering may assist EMS planners at future events.

The objective of this case study was to experimentally manipulate the impact on arousal and recall of two characteristics frequently occurring in gruesome depictions of body parts in smoking cessation advertisements: the presence or absence of an external physical insult to the body part depicted; whether or not the image contains a clear figure/ground demarcation. Three hundred participants (46% male, 54% female; mean age 27.3 years, SD = 11.4) participated in a two-stage online study wherein they viewed and responded to a series of gruesome 4-s video images. Seventy-two video clips were created to provide a sample of images across the two conditions: physical insult versus no insult and clear figure/ground demarcation versus merged or no clear figure/ground demarcation. In stage one, participants viewed a randomly ordered series of 36 video clips and rated how “confronting” they considered each to be. Seven days later (stage two), to test recall of each video image, participants viewed all 72 clips and were asked to identify those they had seen previously. Images containing a physical insult were consistently rated more confronting and were remembered more accurately than images with no physical insult. Images with a clear figure/ground demarcation were rated as no more confronting but were consistently recalled with greater accuracy than those with unclear figure/ground demarcation. Makers of gruesome health warning television advertisements should incorporate some form of physical insult and use a clear figure/ground demarcation to maximize image recall and subsequent potential advertising effectiveness.

Prolonged standing is one of the common activities in electronic industry as the task requirement. Prolonged standing can cause discomfort on the body of the workers and can lead to injury and occupational disease. The purpose of this study is to investigate standing workers perception on the fatigue and the discomfort on their respective body region for 12 hours working time. The subjects are the 80 workers with a good health condition and at least 6 months tenure. The subject data are collected via questionnaires and Likert scale to define the discomfort, pain, and fatigue. The workers were interviewed regarding their job and perceived fatigue discomfort. The results show the domination of the lower body region with the higher mean at the lower back, legs, and foot ankle. No statistically significant differences were found between the job tenure and body part discomfort pain and fatigue. There is a significant relation between gender and discomfort pain on legs and foot ankle. The result also shows a strong relation between age and the discomfort body parts of thigh and foot ankle. The perceptions of the workers towards discomfort pain and fatigue cause by prolonged standing during performing the task. The results from this study will provide a view for industrial consultants or ergonomist with evidence to support for ergonomic interventions for prolonged standing activity such as job rotation and work-rest schedule.

Human body as a universal possession of human beings constitutes an interesting domain where questions regarding semantic categorisations might be sought crosslinguistically. In the following, we will attempt to describe the terms used to refer to the body in Hawrami, an Iranian language spoken in Paveh, a small township in the western province of Kermanshah near Iraqi borders. Due to the scarcity of written material, the inventory of 202 terms referring to external and internal body parts were obtained through a field work, which took a long time, and techniques, such as the “colouring task”, observation and recording the terms as used in ordinary conversations and informal interviews with native speakers. The semantic properties of the terms and the way they are related in a partonymy or locative relationship were also investigated. As far as universals of body part terms are concerned, while conforming to ‘depth principle’ concerning the number of levels each partonomy may consist of, Hawrami violates an important feature of this principle by not allowing transitive relations between different levels of partonomic hierarchies. In addition, Hawrami lacks a term for labelling the ‘whole’.

This study presents a semantic analysis of how emotions and emotional experiences are described in Chinese. It focuses on conventionalized expressions in Chinese, namely compounds and idioms, which contain body-part terms. The body-part terms are divided into two classes: those denoting external body parts and those denoting internal body parts or organs. It is found that, with a few exceptions, the expressions involving external body parts are originally metonymic, describing emotions in terms of their externally observable bodily events and processes. However, once conventionalized, these expressions are also used metaphorically regardless of emotional symptoms or gestures. The expressions involving internal organs evoke imaginary bodily images that are primarily metaphorical. It is found that the metaphors, though imaginary in nature, are not really all arbitrary. They seem to have a bodily or psychological basis, although they are inevitably influenced by cultural models.

It is generally assumed that in multicellular organisms the diversity of the different cell types is the result of different gene activity which becomes manifest in the course of development. This theoretical concept of cell differentiation was developed on the basis of results obtained from a relatively small number of suitable experimental systems. One of them comprises the imaginal disks of the fruitfly Drosophila melanogaster . Imaginal disks are larval primordia in holometabolic insects such as flies and mosquitoes, and consist of densely packed populations of morphologically uniform cells. They give rise to defined structures of the adult body (mainly integument), thus replacing parts of the larva which are almost completely histolysed during metamorphosis. The prospective fate of the various imaginal disks can be tested, for example, by transplantation experiments. Individual disks are removed from larvae of a genetically marked strain and transplanted into the body cavity of another larva with which the transplants undergo metamorphosis. The metamorphosed derivatives of the disks are then found in the abdomen of the fly and can be microscopically identified on the basis of the morphology of bristles, hairs and other structural features of the integument. The same method is applied for examination of the developmental performance of disk fragments. From the results of such experiments the following conclusions are drawn: (1) Individual disks of fully grown larvae, that is larvae which are ready to pupate, are determined (programmed) for exactly defined body parts of the adult organism. (2) The individual subregions of such a body part can be localized precisely within a disk. Based on these facts fate maps (anlage plans) can be worked out. (3) From experiments in which different genetically marked disks are intermingled and then transplanted into larvae it is concluded that even single cells are determined for structures of a specific body region.

Abstract The human body is central to myriad metaphors, so studying the conceptualisation of the body itself is critical if we are to understand its broader use. One essential but understudied issue is whether languages differ in which body parts they single out for naming. This paper takes a multi-method approach to investigate body part nomenclature within a single language family. Using both a naming task (Study 1) and colouring-in task (Study 2) to collect data from six Japonic languages, we found that lexical similarity for body part terminology was notably differentiated within Japonic, and similar variation was evident in semantics too. Novel application of cluster analysis on naming data revealed a relatively flat hierarchical structure for parts of the face, whereas parts of the body were organised with deeper hierarchical structure. The colouring data revealed that bounded parts show more stability across languages than unbounded parts. Overall, the data reveal there is not a single universal conceptualisation of the body as is often assumed, and that in-depth, multi-method explorations of under-studied languages are urgently required.

Pulling is one of the manual material handling activities that could lead to work-related musculoskeletal disorders. The objectives of this study were to explore the development of muscular fatigue when performing intermittent pulling tasks and to establish models to predict the pull strength decrease due to performing the tasks. A simulated truck pulling experiment was conducted. Eleven healthy male adults participated. The participants pulled a handle with a load of 40 kg, which resulted in a pulling force of approximately 123 N. The pulling tasks lasted for 9 or 12 min with one, two, or three pauses embedded. The total time period of the embedded pauses was 3 min. The pull strength after each pull and rest was measured. Ratings of the perceived exertion on body parts after each pull were also recorded. The results showed insignificant differences regarding the development of muscular fatigue related to rest frequency. We found that the development of muscular fatigue for pulling tasks with embedded pauses was significantly slower than that for continuous pulls. The forearm had a higher CR-10 score than the other body parts indicating that the forearm was the body part suffering early muscle fatigue. An exponential model was developed to predict the pull strength of the pulling tasks with embedded pauses. This model may be used to assess the developing of muscular fatigue for pulling tasks.

Workers' compensation claims associated with manual materials handling (MMH) represent the single largest source of claims and costs. There have been few analyses of such losses associated with MMH. An examination of the nature of the injuries associated with MMH as well as the body parts most frequently affected can lead to a better understanding of the losses attributed to MMH to suggest further research efforts. A large sample of MMH claims was analyzed and stratified with respect to body part affected and the nature of the injury. The cost distribution associated with the claims was considerably skewed, and an attempt to fit several known distributions to the data did not produce a statistically-significant fit. The lower back area and upper extremities were the body parts associated with the majority of claims. Strain was the nature of injury most frequently reported (51.3%). Lower back area strains were the most frequently reported nature of injury and body part combination.

Tactile distance judgments are prone to a number of physiological and perceptual distortions. One such distortion concerns tactile distances over the wrist being perceptually elongated relative to those within the hand or arm. This has been interpreted as a categorical segmentation effect: The wrist implicitly serves as a partition between two body part categories so that stimuli crossing the wrist appear further apart. The effect could alternatively be explained in terms of specialized acuity at anatomical landmarks (i.e., the wrist). To test these opposing explanations we presented participants with two tactile distances sequentially for comparison (one mediolaterally, across the arm, and the other proximodistally, along the arm). Points-of-Subjective-Equality (DV) were compared on the hand, wrist and arm, on dorsal and ventral surfaces between subjects. If the acuity account were true distances would be elongated in both axes at the wrist. If the categorical segmentation account were true there would be a selective perceived increase of the proximodistal distance at the wrist. A previously reported mediolateral bias was found on all body parts but, consistent with the categorical account, at the wrist the magnitude of the bias was either reduced (dorsally) or not found (ventrally) suggesting a selective proximodistal elongation. We found no evidence of increased acuity in the vicinity of the wrist in this task. Therefore we conclude that the segmentation of the body into discrete parts induces categorical perception of tactile distance.
