Full textAbstract:
Body image involves perceptions, attitudes, and beliefs concerning one’s body, while body schema involves the sensorimotor capacities to control movement and posture. A review study is needed to obtain sufficient data to determine the effect of body awareness on the normal development of children. This study is a systematic review of interventions related to body awareness among typically developing children. Studies focusing on interventions related to body awareness from 2010 to 2021 were analyzed and extracted from four major scientific databases, and the three that met the inclusion criteria were analyzed. Methods were analyzed by frequency, and the results were analyzed by calculating effect sizes. Two studies involved a nonrandomized two-group design and a single-case experimental study. Two studies targeted early childhood, and one study focused on middle childhood. This review indicates that determining the effectiveness of interventions related to body awareness is necessary for typically developing children because body awareness is a potential influencing factor in their development. Additional research is needed to determine the effectiveness of body awareness assessment tools and interventions.

Full textAbstract:
Introduction: The notion of body or body perception is of great importance in the development of motor skills and functionality. In atypical development situations, as in the case of Down syndrome (DS) there is a delay in the development and motor skills are compromised, which possibly is reflected in the quality of body self-perception in children with DS.
Objective: To assess the characteristics of body self-perception in school age children with DS.
Methods: This is an exploratory and descriptive study involving 10 children aged between seven and nine years. To assess body perception, it was used the Body Notion factor from the Psychomotor Battery (BPM). Data analysis was performed qualitatively and quantitatively according to the criteria established by the instruments and the researchers.
Results: The participants' performance regarding the notion of body was not related to their age. The right and left discrimination capability was the body notion sub-factor with the worst performance and the self-image was the sub-factor with the best performance. The drawings of the human figure were split into two categories: unidentifiable (Class A, n = 8) and recognizable (Class B, n = 2).
Conclusion: It is suggested that the self-perception of children with Down Syndrome analyzed in this study has a strong relationship with the body and environmental stimuli together with psychomotor and cognitive development, which, however, does not coincide with their chronological age.

Full textAbstract:
Feeding problems, such as picky eating and food avoidance, are common in youth with autism. Other feeding and eating problems (e.g. disordered eating, fear of trying new foods, and insistence on specific food presentation) are also common in this population. This scoping review describes the nature and extent of feeding and eating problems in autistic youth and reports characteristics of autistic youth who experience such issues. Thirty-four studies were included in the current review, with almost all studies (91%) investigating feeding problems. Only 9% of studies examined concern with weight, shape, and/or body image, but several authors noted that disordered eating attitudes and behaviors may occur more frequently in those with autism than their peers without autism. No common individual characteristics (e.g. cognitive functioning and autism symptom severity) were identified for youth who experience feeding or eating problems. Although differentiating “feeding” from “eating” problems is critical for accurate identification and treatment of these issues, the existing literature has failed to do so. We propose that in future research “eating problems” be used when behaviors involve preoccupation with food, eating, or body image, and “feeding problems” be used when such preoccupation is absent. Lay abstract Feeding problems, such as picky eating and food avoidance, are common in youth with autism. Other, broader difficulties with feeding and eating (eating disorder symptoms such as restricting food intake or preoccupation with body shape or weight and insistence on specific food presentation) are also common in autistic individuals. Here, we describe the nature and extent of feeding and eating problems in youth with autism. We found no common characteristics (such as severity of autism symptoms) that best describe autistic youth who experience problems with feeding or eating. Almost all studies we reviewed focused on problems with feeding (selective or picky eating), and only a few studies focused on eating disorder symptoms (concern with weight, shape, and/or body image). However, some researchers reported that eating disorder symptoms may occur more often in autistic individuals compared to their peers without autism. Many studies used the terms “feeding” and “eating” problems interchangeably, but understanding the difference between these problems is important for researchers to be consistent, as well as for proper identification and treatment. We suggest future researchers use “eating problems” when behaviors involve preoccupation with food, eating, or body image, and “feeding problems” when this preoccupation is absent. We highlight the importance of understanding whether feeding or eating problems are separate from autism traits, and the role of caregivers and other adults in the child’s treatment. Considerations for health-care providers to assist with diagnosis and treatment are also provided.

Full textAbstract:
Purpose: To describe multidisciplinary interventions aimed at treating a child diagnosed with an autism spectrum disorder. Case description: The mother sought medical help for her son who exhibited language delays. He was agitated, did not respond to calls, and exhibited a delay in speech development. For psychopharmacological treatment, risperidone 1 mg/mL associated with vitamin D, was prescribed. Multidisciplinary therapies were proposed and applied according to the patient’s needs. In sessions with a speech therapist, he responded to all stimuli, demonstrating good interest in the proposed activities and maintained good eye contact. He performed several circuits to improve posture, image, laterality, and body scheme. After participating in hippotherapy supervised by several professionals, the child exhibited an improvement in social interaction, motor performance, especially in posture practice, and in communication. After interposing equine-assisted therapy with intellectual clinic sessions, he started activities at an inclusive school. Discussion: Multidisciplinary interventions demonstrated effectiveness and continuous and positive evolution in the patient. Studies reporting multidisciplinary therapies are relevant for demonstrating the importance of this method and the adaptation to the reality of each autistic patient.

Full textAbstract:
123I-meta-iodobenzylguanidine (123I-mIBG) scintigraphy is used for evaluating disease extent in children with neuroblastoma. 131I-mIBG therapy has been used for evaluation in children with high-risk neuroblastoma, and post-therapy 131I-mIBG scintigraphy may detect more lesions compared with diagnostic 123I-mIBG scintigraphy. However, no studies have yet revealed the detection rate of hidden mIBG-avid lesions on post-therapy 131I-mIBG whole-body scan (WBS) and SPECT images in neuroblastoma children without mIBG-avid lesions as demonstrated by diagnostic 123I-mIBG scintigraphy. We retrospectively examined the diagnostic utility of post-therapy 131I-mIBG scintigraphy in children who received 131I-mIBG as consolidation therapy. Nineteen children with complete response to primary therapy were examined. Post-therapy 131I-mIBG scintigraphy was performed four days after injection. The post-therapy 131I-mIBG scintigraphy, 4 children exhibited abnormal uptake on the WBS. Post-therapy 131I-mIBG SPECT/CT provided additional information in 2 cases. In total, 6 children exhibited abnormal uptake. The site of abnormal accumulation was on the recurrence site in one case, operation sites in five cases, and bone metastasis in one case. Post-therapy 131I-mIBG scintigraphy could detect residual disease that was not recognized using diagnostic 123I-mIBG scintigraphy in 32% of children with high-risk neuroblastoma and ganglioneuroblastoma. The diagnostic use of post-therapy 131I-mIBG scintigraphy can provide valuable information for detecting residual disease.

Full textAbstract:
Purpose: Development and clinical testing of methodology dosimetry planning of radionuclide therapy based on Monte Carlo simulation of radiation transfer process.
Material and methods: The method of determination in absolute units of radiopharmaceutical (RP) activity accumulated in tumor lesions. The technique is based on scintigraphy syringe containing diagnostic RP activity, biplane patient scintigraphy after injection of the RP and determination of the RP accumulation when administered calculated using the Monte Carlo method for the absorption and scattering of radiation in the patient’s body and in the collimator of the gamma camera. Code MCNP Monte Carlo simulation was used. The layout of determination of the value of accumulated RP activity in the patient’s tumor site implies successive implementation of the following three steps.
1. Scintigraphic images are obtained of the vial containing already known activity of the RP placed at the fixed source-to-collimator distance, following
which estimation of the detector count rate within the specified region of interest of the vial image is undertaken.
2. Therapeutic activity A0 is introduced in the patient’s body, scintigraphic examination of the patient is performed. Estimation of the detector count rate in the region where the tumor is located and the value of tissue background in the close enough vicinity to the tumor is performed using the tools for contouring the region of interest on the obtained planar image provided using the software imbedded in the scintigraphic equipment.
3. Value of accumulated activity RP in the affected tumor is determined according to the correction factor which is calculated using Monte-Carlo method for specific clinical case for the geometry used in obtaining scintigraphic images which is identical to the conditions of measurement of activity in the vial and in the patient’s body. The technique has been tested in the study, with an injection of 30 MBq of 123I-MIBG child with neuroblastoma.
Results: The level of accumulation of radiopharmaceutical in the tumor of the adrenal gland was 0.78 MBq, i.e. 2.6 % of the administered activity. This corresponds to literature data (average about 2.4 %) for scintigraphic studies of children with neuroblastomas. When using the known calculation method for analytical formula without the introduction of corrections for the absorption and scattering of radiation was obtained a result of 1.02 MBq, i.e. overestimation was 31 %.
Conclusions: Introduction calculated by the Monte Carlo method for the absorption and scattering of radiation during scintigraphy patient can improve the accuracy of dosimetry planning of radionuclide therapy.

Full textAbstract:
Abstract Background: Laron syndrome (LS), which can be defined as primary growth hormone resistance or insensitivity, is a rare genetic disease inherited by an autosomal recessive trait. Although it is undistinguishable from growth hormone deficiency, LS has high levels of growth hormone, but insulin-like growth factor (IGF-1) cannot be synthesized. Mecasermin treatment is the only option for the patients who suffer from LS. This study aims to research cardiac findings of children with LS, who receive treatment with mecasermin. Methods: The study enrolled five children four males and one female, 4 M/1 F with LS, two of whom were siblings with a mean age of 6.3±2.1 years, a body weight of 13.36±4.74 kg, a height of 88±8.7 cm, and a body mass index (BMI) of 16.47±3.35. Their demographic data were obtained from their family and files. The children received mecasermin via subcutaneous injection at 0.04–0.12 μg/kg doses twice per day. The duration of mecasermin treatment was 8–53 months. All of them were examined clinically by electrocardiogram and echocardiogram. Results: Their cardiac examinations were normal, except for one case, who had systolic murmur at cardiac auscultation. Arrhythmia was not observed on their electrocardiograms. The echocardiograms did not show a significant congenital cardiac anomaly. Their cardiac measure and functions were within normal ranges. The echocardiogram of the child with the murmur showed mitral and tricuspid insufficiency. The Doppler images showed pulmonary hypertension findings. These findings were proven by angiography. The vasoreactivity test results of that patient were negative. No reason could be found for the observed pulmonary hypertension. We diagnosed this finding as a primary pulmonary hypertension and Bosentan therapy was started. Conclusions: In this study, we showed that cardiac findings were consistent with previous studies. To the best of our knowledge, the observed pulmonary hypertension in children with LS, who received treatment with or without mecasermin, is reported for first time in the literature.

"A pilot study of influence of pedicle screw instrumentation on immature vertebra: a minimal 5-year follow-up in children younger than 5 years." Journal of Neurosurgery: Pediatrics 23, no. 6 (June 2019): 680–87. http://dx.doi.org/10.3171/2018.12.peds18622.
Full textAbstract:
OBJECTIVEConcerns remain over the influence of pedicle screw instrumentation on the growth potential of an immature spine. Previous studies have reported discrepancies between animal experiments and clinical studies. The authors’ objective was to explore the influence of pedicle screw instrumentation on the growth of an immature spine at a very young age.METHODSIndividuals who met the authors’ criteria were included. Anteroposterior diameter of the vertebral body; pedicle length on both sides; and anteroposterior diameter, transverse diameter, and area of the spinal canal were measured on CT images before surgery and at the final follow-up. Parameters of instrumented vertebrae and adjacent noninstrumented vertebrae were compared. The growth value and growth percentage of each parameter were calculated. Subgroup comparisons were made in thoracic vertebrae and lumbar vertebrae. Statistical analyses were performed.RESULTSThirteen patients with a congenital spinal deformity were included in the study. The average age at surgery was 3.4 (range 2–5) years, and the average follow-up was 7.2 (range 5–11) years. Osteotomy and short instrumentation with pedicle screws were performed in each case. A total of 69 segments were measured, including 43 instrumented vertebrae and 26 immediately adjacent noninstrumented vertebrae. Significant increases in all parameters were noted at the final follow-up. In instrumented vertebrae, growth of the pedicle length and the anteroposterior diameter and area of the spinal canal increased significantly, while growth of the anteroposterior diameter of the vertebral body decreased significantly compared with noninstrumented vertebrae. Similar results were noted in the lumbar region. The shape-change phenomenon was found in noninstrumented vertebrae but was not apparent in instrumented vertebrae.CONCLUSIONSPedicle screw instrumentation may slow down growth of the vertebral body, indirectly speed up growth of the spinal canal, and hinder the shape-change phenomenon of the lumbar spinal canal. However, the influences were quite slight, and significant development did occur in instrumented vertebrae. Therefore, pedicle screw instrumentation may not have much effect on the growth of immature vertebrae in children younger than 5 years.

Full textAbstract:
As a result of archaeological observations in Derbent, carried out in 2020, a Muslim burial ground was discovered, representing a section of the medieval northern city necropolis, located behind the northern city defensive wall. More than 80 sarcophagus-like gravestones were discovered, made of a single stone monolith and consisting of an upper part - a body and a protruding rectangular plinth. They are of three main types: 1 - with a semicircular cross-section of the body (semi-cylindrical), 2 - with a lancet cross-section, 3 - with a rectangular cross-section of the body. There are sarcophagi nos. 1-3, two of which (sarcophagi nos. 1, 2) have figured images on the top of the case - this is an eight-pointed star or a simplified octogram - the famous Muslim symbol rubʿ al-Hizb or najmat al-Quds, associated with one of the main Muslim shrines - the Dome of the Rock (Masjid Qubbat as-Sahra) mosque in Jerusalem, but also known in the literature as the “Selçuklu Yıldızı” (Tur. Selçuklu Yıldızı), which became widespread in the Seljuk Empire in architectural decor and decorative and applied arts art ceramics, metal) in various variations. The length of the body of the identified sarcophagi ranges from 52 to 266 cm with a width of 19 to 68 cm and a height of 13 to 56 cm; the length of the plinth ranges from 68 cm to 288 cm with a width of 40-95 cm and a thickness of 5-10 cm. Obviously, the size of the sarcophagi reflects three age categories of the buried: children, adolescents, and adults. Sarcophagus No. 40 has an epitaph in Arabic in the Kufi script of the 11th-12th centuries.All in situ sarcophagi are oriented to the west and indicate the location of burials beneath them, apparently having the same orientation and made in elongated rectangular stone boxes (cysts).The revealed sarcophagi dating back to the last third of the 11th - 12th centuries. and their appearance in Derbent and Dagestan is associated with the Seljuk military-political and ethnocultural expansion in the Eastern Caucasus.

Full textAbstract:
There is a need to look at the determinants of exercise behavior in adolescents, as there is a large deficit of research concerning this population. The purpose of this study was to examine Social Physique Anxiety (SPA) and the body shape of adolescents participating in a semester of physical education class. A secondary purpose was to create general profiles by combining the SPA information and the Transtheoretical Model (TM) of behavior change. Middle school students (N= 374) participated by completing a regularly scheduled physical education class and completing the Exercise Behavior Change Survey (which assessed Body Shape, SPA and TM) pre and post semester. The study revealed participation in class had no effect on SPA levels or Body Shape scores, nor did the study reveal any gender differences with these two concepts. Concerning the TM, SPA may not be a factor for progressing through the stages of change, although it may effect which processes were utilized and how one identifies the pros and cons of exercising. The Social Physique Anxiety Scale only reached an alpha of .50, possibly contributing to the lack of relationship between SPA and TM.School of Physical Education

Full textAbstract:
African American children are disproportionately over-represented in the child welfare system. Many of these children linger in the system and experience disconnection from their biological families, communities, cultural beliefs, values, and practices. Familial socialization and cultural exposure are essential to developing a positive ethnic identity and self-concept. For African American female adolescents, hair and hair care are critical areas for such socialization and support. This qualitative study explored the hair and hair care perceptions and experiences of African American female adolescents in foster care. The goal was to examine hair and hair's connection to, and influence on, sense of self and self-esteem for African American female adolescents in foster care.
Eleven African American female adolescents participated in individual interviews, and grounded theory was used to analyze the data. Four major themes emerged: hair care, perception of hair and identity as an African American female, societal influences on self-awareness, and influence of the foster care system. Results from the study indicated African American female adolescents in foster care identify hair as important. Participants noted hair is connected to appearance and shapes who they are and how they view themselves as African American females. Participants addressed the complexity of hair and politics associated with hair. The findings further emphasized the role of racial socialization and the importance of a supportive hair care environment. Participants also discussed their awareness of societal influences on their perception of African American women. They offered recommendations for improving the hair care experiences of African American children in foster care, for supporting positive development of identity and self-esteem, and for implementing standards of practice that will ensure these youths' cultural needs are addressed in the child welfare system.

Full textAbstract:
This study examined the differences between eating disordered and non-eating disordered women on self-deficits, specifically self-esteem, body-image disturbance, and body dissatisfaction. In addition, the existence of a cultural and individual ideal body shape was investigated. It was expected that eating disordered women, compared to non-eating disordered women would exhibit lower self-esteem, higher body dissatisfaction and a greater degree of body overestimation (as measured by the waist). Furthermore, it was expected that eating disordered women would choose a thinner cultural and individual ideal shape than the non-eating disordered women.
The subjects were 82 females aged 19 to 40 years. The eating disordered group was recruited from a local support group and subjects met either the DSM-III (1980) criteria for anorexia nervosa, or Russell's (1979) criteria for bulimia nervosa. None of these subjects were hospitalized at the time of testing. Non-eating disordered subjects were nursing students recruited from a local college. The Eating Attitudes Test was administered to these subjects as a screening device to ensure that no subjects were included who had a mild eating disorder. All subjects completed a test package: The Eating Attitudes Test; The Adult Self-Perception Profile; The Eating Disorder Inventory; and a demographic sheet. At a second interview, subjects completed a body-image estimation procedure (Askevold, 1975), the cultural and individual ideal questions (Perceived Body Image Scale, Manley & LePage, 1986), and were weighed and measured for height.
A one-way multivariate analysis of variance was computed for measures of self-esteem, body dissatisfaction and body-image disturbance, examining differences between the two groups. Significant differences were found for self-esteem and body dissatisfaction (p < .001), with body-image disturbance approaching significance (p < .06). An investigation of the means revealed that eating.disordered women showed less self-worth, more ineffectiveness and experienced greater body dissatisfaction, than did non-eating disordered women. While body-image disturbance was present in both groups, the eating disordered group showed a slightly greater tendency to overestimate
their waist area than did the non-eating disordered group. A Chi square analysis computed for the cultural and individual ideals revealed the eating disordered group chose a significantly thinner cultural ideal shape (p < .05) and individual ideal shape (p < .001) than the non-eating disordered group. Both groups chose a very narrow range of acceptable female shapes to represent the cultural and individual ideal body shapes. Implications for these results and suggestions for future research are discussed.Education, Faculty of

Full textAbstract:
Incidence of childhood obesity has increased dramatically within the last 30 years. Childhood obesity is of concern because of the associated health problems, and because childhood obesity often tracks into adulthood. There is a clear association between activity-level and obesity. Therefore, it is important to consider physical activity patterns in the treatment and prevention of childhood obesity. Childhood is a key time period to intervene in the formation of habits and patterns associated with physical activity that may reduce obesity. To date, few studies have focused on the level of examining obese children individually.
This case study focused on the physical activity patterns of 4 obese 6-10 year olds (two boys, two girls). All of the participants were above the 99th percentile for weight and had a body fat percentage exceeding 45%. Lipid profiles of the participants revealed that three of the four had high total cholesterol, indicating an increased risk for cardiovascular disease. All of the participants were close to or exceeded the waist to hip ratio value that indicates very high risk for cardiovascular and related diseases (>0.82 for boys, >0.94 for girls).
Use of the Caltrac accelerometer, KIHD 24-Hour Total Physical Activity Record and System for Observing Fitness Instruction Time revealed that the obese 6-10 year old participants averaged 1.85 minutes of moderate to vigorous physical activity (MVPA) per lunch recess time. When extrapolated, the data revealed that the participants spend less than 20 minutes a day in MVP A. This is less than MVP A norms of children in the same age group. The obese participants were not meeting the current recommendations for 60 minutes or more a day for MVPA.
Furthermore, the activity patterns of the participants differ from those of normal weight children. Although children in general and the participant's tend to choose low level activity over MVP A, the participants spent more than 16.5 hours per day in sedentary physical activity, which is more than their normal weight counterparts (10.4 +/- 0.8).

Full textAbstract:
The purpose of this research is to examine through sociological and psychological theories how women make sense of the desire and attainment of breast implants for graduation. The study used a qualitative approach and focused on women ages 18-35 in the state of Texas who have received breast implants for graduation. The sample size in this study included 10 high-school graduates receiving implants as a gift and their 10 mothers. Seven theoretical paradigms provided a better understanding for why the daughters asked for breast implants and why the parent(s) paid for them. Symbolic interaction theory explained why the daughters wished to replace their "fake" cotton padded self with their augmented self, to become the most authentic woman possible. Social construction of reality theory explained why both mothers and daughters wanted to conform to the social construction of gender, and to accomplish their gender well. Conspicuous consumption theory demonstrated how cosmetic surgery practices allow women to appear wealthy, gain status, and "flash" their assets. Feminist theory explained why some women were motivated to capture the attention of men and others altered the body out of empowerment. Reference group and social comparison theories explained how the women in this study were influenced to undergo cosmetic surgery by ranking themselves in attractiveness against real friends and media icons. Lastly, self-discrepancy theory showed how the daughters in this study felt they needed surgery to fix a discrepancy between their real and ideal self. The majority of respondents expressed complete comfort with their gifting and receiving of breast implants for graduation, claiming it was a great decision. They also agreed surgery was worth any risk to increase their daughter's confidence. Most of the mothers expressed that they were comfortable with their decision to gift surgery to their daughters, despite knowing that their gift of augmentation would ultimately result in more surgery in the future.

The process of economical development has changing with the consumption modes.The modes have been changing from agrarian economy,goods-based industrial economy,service economy into the era of experience economy.“Welcome to the emerging experience economy”published by Pine and Gilmore in 1998 showed that experience economy has four phases to distinguish economy value by goods,merchandises,services and experiences.Experiential Marketing is an important trend upon entering the age of experience economy,which is also a marketing concept with both rationality and emotionality.Customers' decision making would somehow affect by emotional factors.Therefore,the study mainly takes experience marketing into consideration as the focus. The main object is to developing a model suit with the experiential marketing of The Body Shop,therefore,this study is intent to discuss the causal relationship between different concepts about the experential marketing,experiential value,brand image of the The Body Shop:(1)the effect of experiential marketing to behavioral intention;(2)the effect of experiential value to behavioral intention;(3)the effect of brand image to behavioral intention. The method of the study utilized the questionnaire through the experiential customers of THE BODY SHOP.400 sheets of questionnaire were released,and 319 returned,the recovery rate was 79.75%.These gained data would analyzed by descriptive statistics analysis,confirmatory factor analysis,Cronbach'alpha reliability analysis and multiple regression analysis to verify the hypotheses of the study. The discuss of this study progressed theoretical model to The Body Shop.The study showed(1)experiential marketing has a great conspicuous to behavioral intention (2)experiential value has a great conspicuous to behavioral intention (3)Brand image has a great conspicuous to behavioral intention.Inthe end,we hope the result of this study in the further research has a contribution to the development of experiential value.

Full textAbstract:
This dissertation layers trauma studies theory with feminist theories of performance and autobiography to investigate how women's autobiographically based performances of illness experience disrupt and/or reinforce master discourses of medicine, identity, and knowledge. Feminist theories of performance and autobiography share with trauma studies the distrust of traditional frames and mechanisms of representation, and seek to discover new methods of interpreting experiences that lie "outside the realm" of normative discourse. These theories are further linked by their shared focus on agency and identity construction and an understanding of autobiography that emphasizes the limitations of language and memory which allows for aporia, contradiction, and dissonance, and the belief that testimony functions as a politicized performative of truth. Employing these theoretical perspectives, Carr investigates how these performances witness to radical reconfigurations of identity through the transference of trauma into conveyable life narrative -- even when those narratives falls outside the paradigm of traditional storytelling structures. Carr questions how the structures and content of these performances reveal what traumas are inflicted not only through illness, but also through treatment and care within the western medical model. Throughout the study Carr examines the moments when the cognitive structures of trauma are transmitted into performance through a variety of feminist and avant-garde performance techniques. Carr investigates the work of specific performers and contextualizes the performances within popular culture and medical discourse. Performances analyzed include; Robbie McCauley's Sugar, Susan Miller's My Left Breast, Brandyn Barbara Artis's Sister Girl, and Deb Margolin's bringing the fishermen home and Three Seconds in the Key. Carr questions how the formerly or currently ill female body performing in public disrupts notions of fixed and stable identity while examining the myriad identity constructions embedded within illness narrative. Rather than simplistic triumphant stories of individual cure and recovery, these complex expressions of traumatic experience reveal patterns of cultural oppression that keep the ill female body isolated and silenced. This study attempts to intervene in that silence by foregrounding these politicized performances.

Full textAbstract:
Text in EnglishRhythmic gymnastics is a demanding sport that requires the athlete to not only execute the moves and elements required with perfection, but also demands a very specific lean body type in order to compete and be successful within the sport. This study explores retired gymnasts’ experiences of competing in rhythmic gymnastics at an elite level, as well as, exploring their experiences in relation to personal body image satisfaction and eating habits when they enter into retirement from the sport. The aim of this study is to provide an understanding of the athlete’s experiences as a rhythmic gymnast, as well as aspects of body image satisfaction and eating habits, following retirement from rhythmic gymnastics. The study provided a semi-structured interview to seven retired elite rhythmic gymnasts from Canada that had competed at provincial, national, and international levels. The data for this in-depth phenomenological study was obtained through the means of the semi-structured interviews to allow for the researcher to obtain an understanding of each of the gymnasts own personal experiences in their retired years. The transcription of each interview was then analysed and coded, first manually and then electronically using the qualitative coding software program ATLAS.ti, into various categories as well as themes found within the data. Findings were interpreted utilising the method of phenomenology explored themes relating to negative body image and poor eating habits both during their athletic career and after they had transitioned out of the sport and into retirement. In addition, the themes suggested that most of the former athletes still related to their elite rhythmic gymnastics identity with respect to their body image even after years of being in retirement. Participants seemed to highlight difficulties with lower self-confidence and self-esteem, as well as struggles regarding the acceptance of their body type and body image, themes also spoke to some participants’ dissatisfaction towards their new body post gymnastics. Ethical approval was obtained and all ethical standards were maintained throughout the duration of the research.

Full textAbstract:
This study evaluates the school feeding programme at Magog Primary School. It sets out as its objective to find out how the programme operates and its potential impact on school children, including challenges, if any, and recommends solutions to mitigate the challenges. It was motivated by the need to provide information which could be used as a basis to ensure that the nutritional and educational objectives of the National School Nutritional Programme are achieved.
A review of literature demonstrated that, within the developmental framework, the point of view of civil society, government and the academia on the school feeding programmes are a valuable strategy to intervene in the nutritional and cognitive development of learners. It also made it evident that there are diverse views as to whether the School Feeding Programme is achieving its intended objectives.
The findings of this study suggest that, although the programme has the potential to improve nutrition and health, enrolment, attendance and cognitive development, there are still some challenges and areas that need to be addressed and improved. These challenges arise as a result of lack of effective monitoring and evaluation, geographical location of the schools and other implementation flaws. The consequences are that the objectives of the National School Nutritional Programme are placed at risk.Development Studies

Full textAbstract:
AbstractThis chapter adds to a young body of literature exploring the patterns of and motivations for the intra-EU mobility of non-EU migrants. As explanatory factors of these mobilities, recent studies point to the constrained access to work, networks and institutions in the country of residence. The role of children in onward mobilities has received little attention thus far. While offspring are generally theorised as a ‘binding’ factor, research suggests that children can also be central in onward-mobility decision-making. Parents take children’s specific needs and their hopes for their children’s future into consideration within the decision of onward mobility. Children can also move on their own account or stay put while their parents move again. We present a case study to unveil the dynamics within Somali families around the decision to move onwards to the UK. This provides a rich and suitable case, because of the relatively high onward-mobility rates and the great variety in family composition and characteristics. Using a mixed-methods design, we develop, test and contextualise theoretical expectations concerning the relationship between the timing of arrival of children in the host country and their onward migration, with or without their parents. In addition, we empirically address the expectation that independent migration is more common in larger families. A comparison with other young people of refugee background is provided to shed light on the particularities and generalities of our findings.

Full textAbstract:
In neurological illnesses, the body may present itself to perception in ways which allows insights into the concepts of body image and body schema. Three such conditions are explored. From those who live with spinal cord injury, paralysed and insentient from the neck down, aspects of the importance of the body in one’s sense of self are revealed. Some also describe a coming to terms with their altered bodies. When considering the body image, its adaptability and this reconciliation to a new normal should be considered. Studies on acquired severe sensory loss explore how conscious control, at the body image level, may partially replace the deafferented body schema. There is little evidence, however, for these subjects extending access to previously non-conscious motor schema. Lastly, some narratives from those with congenital absence of movement of facial muscles describe reduced emotional experience and felt embodiment as children. These can be developed as young adults, through shared social interactions. The importance of the social in elaboration of the body image is further implicit in a consideration of the stigma associated with facial disfigurement. Others’ responses to one’s body are crucial in developing our body image and sense of self.

ABSTRACT Children have an essential place in the world population which we can’t regard. On the contrary, as the most special group of the society, by being the residents of the future cities, they are excluded from the urban life and the planning process. This situation makes the questionable togetherness of city and children become more of an issue. Before getting in action, in order to find solutions to the problem, the aim of this paper is to understand how children perceive their cities and form the image of their urban environment. Accordingly, three case studies (sites of Powisle, Sathyanagar and Enschede), which fosters the participation of children by using the methods of one-on-one interviews, focus groups, peer-interviews on video, participant- taken photographs, mapping of roaming range, participant-led guided tours, photo-grids and community surveys, have been reviewed in this study from the perspective of children. The form of the cities were examined by using the urban elements of Kevin Lynch (paths, edges, districts, nodes, landmarks) as a common frame. The results show major differences in perception of children and adults which empowers the studies made on city and children including children’s participation.

Background: As adults, over-nutrition in children due to fast food intake becomes a major issue because it raises the risk of different diseases. Previous studies. A correlation between spending money on consumption patterns is stated, but further study of the correlation to over-nutrition is required. This study aimed to analysis the association between pocket money and the frequency of fast-food consumption toward overnutrition among junior high school students. Subjects and Method: This was a cross-sectional study carried out at Junior High School 98, South Jakarta, Indonesia. This location had a strategic location for fast-food traders. A total of 216 students’ grade-8 (13-15 years old) were selected for this study. Variables in this study were pocket money, fast food frequency, and overnutrition. The data were collected using data Food Frequency Questionnaire (FFQ), Body Mass Index (BMI) measurements, and questionnaire. The data were analyzed based on the z-score table from World Health Organization (WHO). Results: There was a significant correlation between pocket money and overnutrition, and it was statistically significant. Pocket money ≤ IDR 20.000 had a greater indicated overnutrition which is influenced by several conditions. However, there is no significant correlation between the frequency of fast-food consumption and overnutrition. Conclusions: Pocket money is correlate with overnutrition among junior high students.

Full textAbstract:
This paper discusses an experimental study of the flow field around three different wall-mounted obstacles in a boundary layer within a relatively shallow flow (d/H ≈ 4, where d is the flow depth and H is the obstacle height). The first two obstacles consist of a semi-ellipsoidal body with the major axis of the base ellipse oriented in the streamwise and the transverse direction. The third obstacle is a low-aspect-ratio cylinder, bearing greater similarity to geometries investigated in other studies. Reynolds numbers of 5500 and 17800, based on obstacle height, were investigated. Digital particle image velocimetry was used to characterize the flow field in each case. At ReH = 17800, isocontours of streamwise vorticity reveal the presence of a tip vortex pair and a base vortex pair for each geometry; however, the ratio of the relative strengths of the tip and base vortices varies considerably, with the streamwise-oriented ellipsoid having the largest ratio of tip/base vortex circulation and the transverse ellipsoid having the smallest ratio. The presence of a base vortex for such low-aspect-ratio obstacles is unexpected, and therefore we hypothesize that its existence is related to the small d/H. It is anticipated that variation of geometry and d/H will help to elucidate the role of the base vortex in the three-dimensional vortex structure of the wake.

Full textAbstract:
Abstract This study examines an important channel sand reservoir in the Junggar Basin, which has a reservoir quality that varies greatly in the vertical and horizontal directions due to the presence of tight sandstones deposited under different sedimentary conditions. Studies confirmed that the high-energy sandstone deposits have good porosity and permeability based on the core data. The channel sand is 20 m to 30 m thick in the Qigu formation and can be divided into three to four channels. Identifying and characterizing the high-energy sandstone "sweet spots" was the objective of this case study. In order to find the sweet spot in this reservoir, high-definition oil-base mud microresistivity image logs were acquired in five exploration wells. The image logs made it possible to identify the different kinds of sandstone reservoirs based on sedimentary structure and texture. Parallel bedding, deformed bedding, cross bedding, and massive bedding were all identified. The paleocurrent energy was from high-to-low and from bottom-to-top in a single channel sand body. The core and production data validated the reservoir qualities, which were identified from the sedimentary features. The channel sand was divided into three to four multistory sand bodies based on image logs. As a result, the typical channel-levee system—composed of massive bedding, cross-bedding and parallel bedding features—was revealed. The massive bedding was mainly at the bottom of the single channel system, surmounted by high-angle cross-bedding, and then finally the parallel bedding intervals. The paleocurrent energy changes from high-to-low vertically within the single channel system. Based on the open-hole and image logs, two types of sweet spots were identified: massive bedding sandstone and high-angle cross-bedding sandstone. These two types were deposited in a high-energy environment which formed the potential sweet spot in the channel complex. The massive bedding intervals, which are mainly in the channel bottom, when cemented by calcite or clay, will become tight sometimes. The high-angle cross-bedding sandstone and uncemented massive-bedding sandstone were the potential target zones for the horizontal well. This case study will show the interpretation of sedimentary features in the channel sand reservoir based on high-definition image logs, to provide a comprehensive understanding of the geologic features that differentiate reservoir quality. The identification of cross-bedding in the channel sand provided a new way to predict possible tight sandstone sweet spots that can help to design horizontal wells.

Full textAbstract:
Rapid and representative reconstruction of geometric shape models from surface measurements has applications in diverse arenas ranging from industrial product design to biomedical organ/tissue modeling. However, despite the large body of work, most shape models have had limited success in bridging the gap between reconstruction, recognition, and analysis due to conflicting requirements. On one hand, large numbers of shape parameters are necessary to obtain meaningful information from noisy sensor data. On the other hand, search and recognition techniques require shape parameterizations/abstractions employing few robust shape descriptors. The extension of such shape models to encompass various analysis modalities (in the form of kinematics, dynamics and FEA) now necessitates the inclusion of the appropriate physics (preferably in parametric form) to support the simulation based refinement process. Thus, in this paper we discuss development of a class of parametric shape abstraction models termed as extended superquadrics. The underlying geometric and computational data structure intimately ties together implicit-, explicit- and parametric- surface representation together with a volumetric solid representation that makes them well suited for shape representation. Furthermore, such models are well suited for transitioning to analysis, as for example, in model-based non rigid structure and motion recovery or for mesh generation and simplified volumetric-FEA applications. However, the development of the concomitant methods and benchmarking is necessary prior to widespread acceptance. We will explore some of these aspects further in this paper supported with case studies of shape abstraction from image data in the biomedical/life-sciences arena whose diversity and irregularities pose difficulties for more traditional models.

Full textAbstract:
Abstract The Dnieper-Donets Basin (DDB) is the principal producer of hydrocarbons in Ukraine and reserves are found in lower Permian and in Visean-Serpukhovian from Lower Carboniferous. The Vodianivske field is located halfway between Poltava and Kharkiv in east Ukraine with proven reserves at depth of 5-6km. Previous studies based on legacy seismic data show thickness changes of the upper Visean towards the main structure and dim small-scale structures on the block boundary. A recent 3D data reprocessing using 5D interpolation and advanced prestack time migration provides a broad frequency content image and imparts detailed high-resolution geological events. While traditional exploration is focused on gas traps in the Visean and below, current study aims to scan for potential traps in the Serpukhovian and above. In order to reveal thin section features, multiple seismic attributes were tested, and spectral decomposition was found to be a powerful tool that delineated thin sand bodies in river valleys and allowed interpretation of high-resolution small-scale faults and pinch-outs not seen before. Frequency tuning analysis on mapped horizons associated with upper Serpukhovian supported the presence of a large deltaic structure revealing SE-NW thin ∼1km wide sand body and developed set of crossing meanders. Similar approach was applied on legacy data expanding to the east and while seismic quality was limited, it was possible to identify a narrow ∼25km length meander and highlight a fault set. Upon seismic attribute study we were able to identify and map thin units associated with sands that can be considered as future targets in hydrocarbon exploration in the area.

Full textAbstract:
This paper presents an empirical approach for flapping-wing aerodynamics using a servo-driven towing tank and a dynamically scale-up robotic manipulator. Time-varying aerodynamic force and moment were measured, and digital particle image velocimetry in multiple cross-sections were conducted. Three case studies showed that the towing tank experiment could be an effective way to investigate the aerodynamic characteristics in detail, which are difficult to be predicted by other conventional approaches. The force and moment measurements clarified that an advance ratio has significant role in governing the LEV behavior and consequent aerodynamic performance of flapping wings. Results for moving sideways showed the effects of the wing-wing and wing-body interaction, and the usefulness of the towing tank experiments for analyzing the flight dynamic characteristics. It was also shown that the towing tank experiments can be applicable to realistic wing motions; test results using the wing kinematics of a living insect in forward flight were well compatible with the trim condition of the insect.

Full textAbstract:
Medical image processing constitutes an important research area of the biomedical engineering since it provides accurate human body information for 3D visualization and analysis, diagnostic, surgical treatment planning, surgical training, prosthesis and implant design, wafer and surgical guides design. Computed tomography (CT) and magnetic resonance imaging (MRI) have had a great impact in the medicine since they can represent complex three dimensional (3D) anomalities or deformities. In this paper, the development of a system for tridimensional visualization and model reconstruction based on CT data is presented. The aim is to provide a system capable to assist the design process of prosthesis, implants and surgical guides by reconstructing anatomical 3D models which can be exported to any CAD program or computer aided surgery (CAS) system. A complete description of the proposed system is presented. The new system is able to visualize and reconstruct bone and/or soft tissues. Three types of renders are used: one for 3D visualization based on three planes, other for 3D surface reconstruction based on the well known marching cubes algorithm, and the other for 3D volume visualization based on the ray-casting algorithm. The functionality and performance of the system are evaluated by means of four case studies. The results have proved the capability of the system to visualize and reconstruct anatomical 3D models from medical images.

The efficiency of the design process in companies today is largely dependent on the skills of individual members of project teams, the capacity of the software available on the market and any assistance provided by the tools and methods found scattered around the industrial world. Within this context, there have been myriad attempts to optimize the different stages in the design process by using computerization, but a growing proportion of current research work on design tends to agree that the crucial point in the act of designing lies in the phase where inventive ideas are sought and that without such ideas being generated, there is no successful future for the product. In the framework of a large number of research activities it has been proven that the TRIZ (the Russian acronym of Theory of Inventive Problem Solving) contribution to the science of design has a promising potential [1–2–3–4]. On the other hand, the added value and spectrum of problem typology where TRIZ could help remains unclear for most researchers for various reasons. Originally, since the theory has penetrated the so-called occidental world, every individual took from TRIZ what he thought was right according to his own knowledge about design, problem solving process, creativity or needs forgetting that 95% of scientific literature about TRIZ’s fundamentals was written either in Cyrillic or in unpublished manuscripts. In most cases, theses multitudes of uses did not see that the original idea of TRIZ was to formulate a theory as strong basement for building methods and tools to satisfy designers expectations. This fact led nowadays TRIZ’s image to fuzziness since available literature on the subject only presents case studies and uses of tools (mostly the matrix) although TRIZ’s scope is much wider. To avoid further aggravation of this fact, this paper aims at presenting the first axiom describing TRIZ’s objectives as a basement for our research activities. Two methodological approaches are then presented : the “trial and error” type approach, which is still very much in use everywhere in industry and which aims to explore an area of solution-seeking, following a structural approach or not, through a series of attempts, which often end up in failure. The second approach is the “convergent” approach proposed by the TRIZ body of knowledge and developed as a contribution to design activity’s efficiency in our research center. This approach aims at limiting the sphere of research during a larger and longer problem statement stage to converge towards a small number of solutions in opposition to traditional approaches which consists in generating a large amount of ideas and select the best suitable ones to be implemented. A case study on the internal ventilation of a car will also be presented to illustrate the quality of the results that could be obtained when applying this convergent approach.
