A Visual Analysis of Male Characters in Disney Animated Movies

This study investigates the visual features of male characters of nine Disney animated movies taken from the last three decades 1990-1999, 2000-2009 and 2010-2019. Aley and Hahn’s (2020) framework of men’s portrayal (developed from Goffman, 1976) is applied. The qualitative analysis reveals that the physical appearance of Disney male characters has changed over time. Body image changed from an unrealistic large body with big muscles to a realistic body type with logical body proportions. Heroes started to be seen as powerful gentlemen rather than heroes with physical strength. Moreover, the heroes, especially in third decade, no longer depended on their physical attire to reflect their ranks. This shift may indicate a change of how people tend to see heroes. In term of masculine touch, male characters used to touch their female companions in a controlling manner. However, in the second and third decade, their touch started to change to protection rather than control. Finally, eye withdrawal remained the same over time because men withdrew their eyes for reasons connected to man’s nature and feelings.

CONSTRUCTION OF NORMS FOR THE VALID PHYSICAL EFFICIENCY TEST FOR PHYSICAL EDUCATION COMMON ENTRANCE TEST (PECET) IN ANDHRA PRADESH

INTRODUCTION:1.“Physical Education may be defined as an education through the physical where many of the educational objectives are achieved by means of big muscle play activities. It is a vital phase of education and an integral part of the total educational process”.The vital phase of education, that is physical education, aims at all round development of an individual where the medium of achieving the goal is physical activity. Hence it is through the big muscle-play activity an individual can enlighten the personality traits such as physical fitness, emotional balance and social behavior etc., besides intellectual development.The physical education programme provides each student with an opportunity to assess his fitness, and to develop skill and understanding that will enable him to enjoy a productive stay in school/college and a more meaningful existence after school/college.

How about you? Ever tempted to use steroids? Well, keep this in mind—not only is it illegal, dishonest, and unfair, but you will be putting your health at risk! You may have heard steroids called roids, juice, hype, or pump. Anabolic-androgenic steroids are powerful prescription drugs that some athletes use not for medical reasons, but as a way to boost athletic performance and build muscle and body mass. They work by acting like the body's natural male hormone, testosterone. Don't confuse them with corticosteroids, which are a different type of steroid used to treat diseases like asthma, arthritis, and many other medical conditions. Remember, steroids might give you bigger muscles, but they cannot improve talent or skill. Athletic ability comes from a combination of things like...

Motor development and emotion recognition among young rural children: The mediating role of working memory

This study explored the relationship between motor development and emotion recognition among young rural children and the mediating role of working memory. A total of 187 children (girls= 41.71%) aged 3-6 years from rural kindergartens in the Henan Province in China participated in the study Their motor development, working memory, and emotion recognition were assessed using the Big Muscle Motor Development Test-Second Edition (fGMD-2), Beads Memory Task, and Emotion Recognition Test. Following a mediating model, results showed that motor development positively predicted working memory, while working memory predicted emotion recognition. The direct and positive predictive effect of motor development on emotion recognition was also significant. The findings suggest that rural children's motor development is a resource for children's emotional recognition, with the mediating role of working memory as a developmental mechanism. We should pay attention to the importance of rural children's motor development in their growth process.

What Would the Child of a Human and a Neanderthal Look Like?

Long ago there were many different species (or kinds) of humans. These included our ancestors, as well as another group, called the Neanderthals, who went extinct and no longer exist. Neanderthals looked very different from us: big muscles, big brains, and no chins. In 2010, scientists managed to study the DNA (genetic code) from these ancient Neanderthals and found, with surprise, that our ancestors had children with them. Neanderthal DNA exists in many people alive today. But we still did not know what the children of humans and Neanderthals (known as hybrids) would look like. By looking at the hybrid children of different kinds of mice, scientists realized that hybrids look very strange indeed. Based on this research, scientists think that human-Neanderthal children would have large heads (even bigger than the Neanderthals) and that their faces would look a little more like humans than Neanderthals.

A new chelid turtle, Prochelidella palomoi sp. nov., from campanian Anacleto Formation, Neuquén Basin, North-Western Patagonia, Argentina.

The new turtle remains were found in the Anacleto Formation (Campanian) exposed in the Aguada Grande site. This area is located 10 km from the south of the city of Rincón de Los Sauces, in the north of the province of Neuquén, Patagonia, Argentina. The specimen (MAU-Pv-AG-452) consists of a partially preserved skull, carapace remains, an almost complete plastron, and a left ilium. The skull shows some features (a developed retropterygoid foramen, and a big muscle attachment area over the basisphenoid) that allow us to refer this specimen to the genus Prochelidella. The visceral view of the first costal bone exhibits deeper axillary buttresses that extend 2/3 of the costal width. This condition is also observed in the costal bone of Prochelidella buitreraensis from the Candeleros Formation (Cenomanian). The scute pattern observed in the anterior lobe of the plastron shows a large gular that extends along the entoplastra length, and small extragulars over the epiplastra. In contrast with the scute scheme observed in Prochelidella cerrobarcinae and Prochelidella portezuelae where the gular does not extend beyond the first 1/3 of the entoplastron. The phylogenetic analyses performed recovered this new species as a member of Prochelidella. The material recovered from the Anacleto Formation represents the first undoubtedly finding of Prochelidella in the late Cretaceous (Campanian) and the second skull recognized for the genus.

Effects of Carbohydrate and Protein Administration by Food Items on Strength Response after Training in Stable COPD.

Background: Chronic obstructive pulmonary disease (COPD) is one of the world’s most common diseases and reasons for death. Systemic consequences, especially reduced muscle strength, muscle mass and muscle function, are common and contribute to worsening prognosis and increasing morbidity and mortality. There is strong evidence that physical activity and strength training are effective in prolonging life and lead to better quality of life. Numerous studies have shown that ingestion of protein and carbohydrates after strength training can increase regeneration of strength in young athletes. Recently, we demonstrated that the same effect can be achieved with these macronutrients administered in a meal. Until now, it is not clear if patients with COPD, integrated in regular physical training, respond similarly. Methods: Prescribed strength training, consisting of two sets circular training with machines for big muscle groups was supplemented with a meal rich in protein and carbohydrates. Changes in maximum strength after 24 h were investigated to find out about the impact of this meal on physical capacity. A pilot study was conducted with pragmatic cross-over design. Results: With nutritive intervention, strength in both knee extensor and chest press were significantly higher than in control training. Conclusion: The study showed beneficial effects for the intake of protein and carbohydrates in changes in maximum strength. For now, the underlying mechanism remains unclear. Clinical relevance needs further research. The study design and study protocol can be used for further studies with only small adaptions.

Research on PEP-3 psychological education evaluation system for disabled children and autistic children in minority areas.

Rehabilitation of disabled children with autism has become a challenge for current rehabilitation centres. This study conducted psychological investigations on disabled children and analysed the symptoms and characteristics of autism in these children to develop more reasonable rehabilitation treatment plans that would help the children receive psychological counselling and effective rehabilitation. This study investigated 107 disabled children from the Disabled Rehabilitation Research Centre of the South China Minority Autonomous Region. Using the PEP-3 scale as a research tool, a questionnaire was developed to investigate and collect data on the mental health of disabled children. The survey was conducted from 2017 to 2021, and 107 children's mental health data were collected in the form of questionnaires based on PEP-3 evaluation indicators. After cleaning the data, the questionnaire data were screened and processed. Descriptive statistical and correlation analysis tools were used for model analysis to understand the overall data distribution and the potential relationships among various data variables. The results of correlation analysis showed that cognition, language expression, language understanding, emotion, and social interaction in the subtest of developmental behaviour were the main indicators of the degree of autism in children. These indicators had a strong and significant correlation with the comprehensive score. Moreover, these indicators had a significant correlation with the individual self-care and adaptive behaviours reported by the children's caregivers. Small muscles, big muscles, and imitation (vision and movement) indicators had a significant correlation with problematic behaviours and physical fitness, and language and cognitive indicators also had a strong correlation with emotion and social interaction. Emphasis should be placed on the improvement of the language and cognitive abilities of disabled children with autism, and corresponding rehabilitation plans, and training can be formulated according to children with different degrees of illness to get a better rehabilitation outcome. Further, identification of key indicators of autism will be of help in aiding the development of rehabilitation treatment for disabled children with autism and formulation of long-term rehabilitation plans.

"Guys with Big Muscles Have Misplaced Priorities": Masculinities and Muscularities in Young South Korean Men's Body Image.

Men’s body image is an issue of increasing importance as related illnesses continue to grow in prevalence around the world. However, cross-cultural attention to men’s body image experiences has been relatively understudied. Based on data derived from cognitive anthropological methods of cultural domain analysis, I develop the concept of “muscularities” to more effectively examine the expectations inherent in multifarious models of body image men continuously navigate. Related to but distinct from “masculinities”—the recognition of culture-bound hierarchies of ways of doing-being a man—“muscularities” attends to the culturally particular ways in which muscles are conceived and evaluated as indices of socioeconomic status, intelligence, social skills, and professionalism, to name a few. Young South Korean men’s experiences of chan’gŭnyuk (“small muscle”) and manŭn kŭnyuk (“large muscle”) challenge universalist assumptions about the kinds of muscles people value in global perspective, demonstrate the necessity of recognizing multiple muscularities in research, and encourage new directions of inquiry that attend to the consequences of variable embodiments of muscularities.

Adenosine triphosphate infusion in patients with cancer pain: a pilot study

Introduction. About 50–66 % patients with cancer suffered from intensive pain when are given analgesics. Objectives. We investigated the effectiveness of intravenous infusion of non-selective purine receptors agonist adenosine triphosphate in cancer patients with moderate and severe pain who had being received non-selective inhibitor of cyclooxygenase plus weak opioid tramadol. Materials and methods. Sixty-seven patients in which pain sensations were localized in different regions were scheduled for the study. The intravenous infusion of adenosine triphosphate 35–45 mcg kg(–1) min(–1) was performed within the period from 100 to 160 minutes. Pain severity was estimated by numeric verbal scale where “0” — no pain and “10” — maximal pain. Moreover, we studied prognostic significance of the original scale that was based on patient’s ability to pointed out precisely the pain sensation margins where “1” — patient can specify exactly the margins of pain sensations on the skin; “2” — patient can indicate approximately zone with pain sensation (periarticular tissue or bone or big muscle); and “3” — patient can determine large anatomical region only. Analysis of correlations was performed between scale value and the effectiveness of adenosine triphosphate infusion. Results. We revealed that 79 % (53 out of 67) patients have pointed out to pain relief after infusion with more than 20 % reduction of pain intensity (p = 0.0000001 — Wilcoxon signed rank test). As results, we obtained statistically correlation link (p = 0.02 — gamma-test and p = 0.02 — Kendall tau rank correlation coefficient) between the adenosine triphosphate infusion effectiveness and pain type with high precision of the pain sensation margins. Conclusions. Intravenous infusion of adenosine triphosphate has the high effectiveness for pain relief in cancer patients particularly when pain sensation margins high precisely detected to be.

Scientific and Methodological Foundation of Improvement of the Students` Coordination Abilities at the Table Tennis Training Lessons

The problems of physical education and health are very important due to the world situation. The article contains information about interests of students of higher educational institutions: we have noted the rising interest to the table tennis, as a spectacular kind of sport.
 Table tennis is one of the most popular kinds of sport among students. It helps to develop following skills: accuracy, speed and reaction speed, explosive power, sense of rhythm operational thinking, the ability to concentrate attention and coordination. Table tennis has been recommended as the most perspective kind of sport, which is available for health.
 The article provides an example of structure and content of physical education training lessons with students of higher educational institutions with the use of table tennis. Students of the experimental group worked at the increasing their coordination abilities at the table tennis lessons. The training was divided into three parts: preparation, the main part and the conclusion. Each part had the own differences. The preparation part took up 12-15% of the total time and was aimed to involve and warm up the big muscles.
 The main part of the lesson took up 75-80% of the total time. This part was divided into three: exercises without the ball, exercises with the ball and the racket, training games. The final part of the lesson was about 10% of the total time. Exercises were aimed at relaxing: breathing, flexibility exercises, jogging, walking.
 In order to improve the coordination skills it necessary to remember for methodological principles: coordination exercises should be at the beginning of the lesson, exercises should be difficult, limited of the number and duration, exercises should be at the defined time, using of the general physical exercises.

Lower leg morphology in runners: forefoot strikers have longer heels but not bigger muscles than rearfoot strikers.

Foot strike pattern used during running may relate to lower leg morphology. We tested the hypotheses that forefoot strike (FFS) runners have longer plantarflexor moment arms (r) and larger plantarflexor muscles than rearfoot strike (RFS) runners. FFS runners had 17% longer r than RFS runners, but all runners had similarly sized medial and lateral gastrocnemius (MG and LG) muscles. Because muscle size also depends on activation pattern ( Ahn et al., 2011), we compared MG:LG activation bias during walking in 24 runners and 23 sedentary subjects. Half of all subjects activated their MG and LG muscles equally ('unbiased') while walking, while the other half activated their MG more strongly than their LG muscles ('MG-biased'). Unbiased sedentary subjects had 16-23% smaller MG muscles compared with MG-biased sedentary subjects, unbiased runners and MG-biased runners. Muscle contraction dynamics during FFS running may balance the effects of longer plantarflexor moment arms in determining MG and LG muscle size.

THE EFFECT OF MUSCLE STRENGTH AND AEROBIC FUNCTION IN THE ELDERLY ACCORDING TO EXERCISE LOAD PATTERN USING INDOOR SMALL CYCLING SYSTEM

We were investigating the muscle strength and aerobic function effect on the aged according to active and passive load using compact cycle system. We recruited twenty old participants and they performed shoulder rotating, upper cycling and lower cycling exercise. We measured the muscular activity, respiratory gas analysis and body heat. The result of muscular activity showed that the passive load could cause muscular activity at 15.4–65.9% compared to active load. We thought that the passive exercise could provide the prevention of spasticity and maintain effect of remaining muscle function in the elderly by caused muscular activity over 50%. The result of oxygen consumption showed that it is the active exercise that used the bigger oxygen consumption at 42.4% during lower cycling. We thought that the active exercise used the big muscles of lower limbs including trunk muscles during lower cycling. The result of body temperature showed that it rises with increase in oxygen consumption and heart rate, and it increased the bigger for lower cycling. The foundation of this study could apply to fundamental research for developing exercise load of indoor rehabilitation exercise system with convenience and easy use to the elderly.

SKIN-MUSCULAR FLAP OF MAJOR PECTORALIS MUSCLE IN PHARYNGOSTOMAS PLASTIC CLOSURE

Laryngeal and hypopharyngeal cancer accounts for 1.5–3.8% of all malignant neoplasms, accounting for more than half of all ENT-cancer patients in the structure of oncological morbidity in Ukraine. Among them more than 60% are found in III–IV stages. Locally diffused larynx and hypopharynx cancer are indications for laryngectomy and resection of the hypopharynx, depending on the extent of the lesion that, in the presence of regional metastases, can be combined with one-or two-way radical or functional neck dissection. Failure to suture the hypopharynx after laryngectomy further leads to the formation of pharyngeal fistulas, suppurations of postoperative wounds, necrosis of the skin and the formation of pharyngostomas. In the plastic closure of the pharyngostomes, regional skin, and facial, and skin-muscle flaps are used, among which the most common is the large chest muscle. The advantages of the flap are the ease of fence, the large volume of plastic material, stability of a “vascular leg”, reliability and short operating time. Our experience with the use of free and regional flap suggests that the musculo-skeletal system of the large chest muscle can be used not only as a “rescue swaddle”, but also, as a first choice in certain clinical situations. 72 patients with laryngeal and hypopharyngeal cancer were included to the study. The age of patients ranged from 41 to 74 years. All patients (100%) had histologically confirmed flat-cell carcinoma of varying degrees of differentiation. Depending on the spread of the cancer process, stage III (T3N0-1M0) was diagnosed in 47 (65.2%), stage IV (T3N2-3M0, T4N0-3M0) in 25 (34.8%) patients. Laryngeal cancer is found in 52 (72.2%), hypopharyngeal — in 20 (27.8%) patients. Plastic closure of pharyngostomas was carried out after 2–3 months after larynectomy, after reduction of inflammation in postoperative wound and clear formation of pharyngostoma edges. The surgical intervention was carried out by two brigades — one brigade carried out the excision of the skin muscle flap, while the other one carried out the removal of the throat wall in the soft tissues of the neck, and then the sheathing of the skin part of the flap was carried out to the edges of the pharyngostomas, and the stitching of the edges of the skin at the point of excision of the flap on the chest wall. The evaluation of the function was performed on the scale of functioning for head and neck cancer patients, PSS-HN (Performance Status Scale for Head and Neck Cancer Patients). The total necrosis of the flap was observed in 2 patients (2.7%) among 72, that were operated as one of the first, at the stage of development of the surgical technique. Partial flap necrosis was observed in 6 (8.3%) patients. Thus, the plastic closure of pharyngostomas with the help of the skin-mimetic flap of the big chest muscle was successful in the vast majority of patients (70 out of 72). The investigation of the functional status of patients on the PSS-HN scale showed a significant improvement and expansion of the diet from 30 to 90-100 points due to the transfer of patients from probe to usual food intake. The public eating habits improved from 25 to 100 points. The operation of the plastic closure of pharyngostomas did not increase the clarity of the language of patients, but created the anatomical conditions for the development of pseudo-voice and vocal prosthesis. So, the using of the skin-muscular flap of major pectoralis muscle in pharyngostomas plastic closure allows achieving satisfactory surgical and functional results.

This research is aimed at increasing rough motor on early childhood. At early childhood, There are a lot of developmental aspects that must be stimulated and one of this is the rough motor movement. Children’s rough motor movement is the ability of children in moving using big muscles. Nowadays there are schools that focused more on the smooth motor movement such as writing, cutting and others that is due to factors of parents and demands of calistung (reading, writing, and counting) to enter the basic education unit. Rough motor movements become abandoned, but researcher intended to increase children’s motor movement, not only in smooth motor movement but also rough motor movement. One of the activity to increase children’s rough motor movement is through dance activities for childrens. Through this dance movement, children’s rough motor movement can be stimulated and children is given varied instruction, not only doing basic movements such as jumping, running and others but the childrens are also able to perform other dance movements accompanied with music. Therefore children is not only learning but also able to recognize fun dance movements.

Actividades Lúdicas “Aprendo Jugando” Para Desarrollar La Motricidad Gruesa En Los Niños Y Niñas Del Primer Año De Educación Básica

The purpose of this current research is to make and implement a didactic guide based on playful activities called “Aprendo Jugando”. This is in a bid to develop the gross motor skills on the first year basic education of boys and girls at Santa Mariana Educational Unit in Riobamba. The guide was organized through a schedule, and it contains games to influence the big muscles movements. The games are intended to reinforce the basic motor skills to evaluate the coordination of the body movements such as jump, match, and jumping on one foot. The sample incorporated 20 children chosen at random. The results were obtained through a direct observation and they were registered with an observation card that was applied before and after the development of the guide. An indicator table was used. Here, the indicators were statistically analyzed, especially the ones that allowed evaluating the hypothesis significance with the use of the students test. At the end of the research, it was concluded that the application of the didactic guide develops the gross motor skills. These evidences play an essential role in the child´s life. As a result, it is recommended to use the guide in a permanent and continuous way because if a child develops the gross motor skills in an appropriate way, he would have confidence on himself. Above all, it will be easier for him to assimilate the basic fine motor skills.

Myositis ossificans traumatica im kraniozervikalen Übergang – Fallbericht und Literaturübersicht

Background Myosits ossificans (MO) is a rare but important differential diagnosis for a heterotrophic bony tumor in the muscles. It is often misdiagnosed as a malignant tumor. With a previous trauma the diagnosis is myositis ossificans traumatic (MOT). In most cases, it is benign and predominantly seen in the big muscles. But there can be malignant etiologies too. Case Description We report a rare case of MO in the muscle of the craniocervical junction. This 37-year-old woman had a riding accident years ago. Because of persisting pain and cervical dysfunction, we did a total resection. Clinical Implications MOT is a benign tumor that can be treated conservative in most cases. In case of persistent pain or neurological deficits, and especially for securing diagnosis, surgical resection is recommended.

This paper is to establish the kinetic and kinematic factors of Apkkoaseogi(front cross stance) Yeopchagi(side kick) in Taekwondo through factors such as movement of the center of the whole body, the angle of the kicking foot, the supporting foot in the lower body, and the muscle activity and then describe the improvement in the skill for the Taekwondo Poomsae players. The study was performed targeting 6 awarded players who had the experience of winning at the national team competition and other nationwide competitions and 6 players who had no experiences at those competitions. After explaining to them the purpose and procedure of the test and getting the written consents from them, the test was conducted.BR For the test, 5 high speed digital cameras(Motion Master 100) and wireless EMG(QEMG-4, Lxtha Korea) were used to collect the data on 5 practices of Apkkoaseogi(front cross stance) Yeopchagi(side kick) in Taekwondo focusing on the movement of the center of the body, the angle of the hip joint, knee joint and the ankle joint, and the muscle activity of the femoral rectus muscle, biceps femoris, gastrocnemius muscle and tibialis anterior. Among them, 1 action which was judged to be the most perfect was chosen for analysis. By removing the first and last 2 seconds in the signal of surface electromyography stet, the root mean square(RMS) and the % MVIC value were obtained for analysis. For the processing of the data, SPSS 21.0 software was used and the analyzed values were obtained including the average(M) and standard deviation(SD). For the identification of the difference between the awarded players and the non-awarded players, the independent sample t-test was conducted and the significant statistical level was set as(p .05). The results were as follows.BR 1. Duration of Apkkoaseogi Yeopchagi in TaekwondoBR The duration of Apkkoaseogi Yeopchagi in Taekwondo at each phase showed a significant difference at the phase of P4(p .05).BR 2. The Movement of the center of the body at Apkkoaseogi Yeopchagi in TaekwondoBR 1) As for the change in the movement of the center of the body of the longitudinal axis(Y axis), there were statistically significant differences in E1 Phase(p .01), E2 Phase(p .01), E3 Phase(p .01), E4 Phase(p.01), E5 Phase(p .05) and E6 Phase(p. 05).BR 2) There were also statistically significant differences in the change in the movement of the center of the body of the vertical axis(Z axis) at the stages of E2 Phase(p .05), E3 Phase(p .05), and E4 Phase(p .01).BR 3. Angle of lower body in the action of Apkkoaseogi Yeopchagi in TaekwondoBR 1) There were statistically significant differences in the right hip joint in E2 Phase(p .01), E3 Phase(p .01), and E6 Phase(p. 01). There was a statistically significant difference in the left hip joint at the Phase E4(p.01).BR 2) There was a statistically significant difference at the right knee joint in E6 Phase(p .01) while there was a statistically significant difference(p .05) at the left knee joint in Phases E2 and E6.BR 3) There was also a statistically significant difference at the right ankle joint in the phase E4(p .05).BR 4. Muscle activity in the lower body at Apkkoaseogi Yeopchagi in TaekwondoBR 1) There were big muscle activities in the left and right side of the femoral rectus muscle and the statistically significant difference between them.BR 2) There were big muscle activities in the right side of the biceps femoris and the statistically significant difference.BR 3) There were big muscle activities in the right side of the gastrocnemius muscle and the statistically significant difference.BR In conclusion, the Apkkoaseogi(front cross stance) Yeopchagi(side kick) in Taekwondo needs a stable movement of the upper body and a stable posture of the kicking foot as well as the balance of the supporting foot. For a strong, fast Yeopchagi of 170°, there is a need for a strong power of repulsive power using the ground, the sequential use of the joints and the flexibility of the lower joints. For an effective Yeopchagi, the understanding and the repetitive training are required through a scientific approach and practices for strengthening the main muscle and the flexibility are required.
