Many factors affect foot and ankle biomechanics during walking, including gait speed and anthropometric characteristics. However, speed has not been taken into account in foot kinematics and kinetics during walking. This study examined the effect of walking speed on foot joint motion and peak plantar pressure during the walking phase. Eighty healthy subjects (40 men, 40 women) were recruited. Maximal dorsiflexion and excursion were measured at the first metatarsophalangeal joints during walking phase at three different cadences (80, 100, and 120 step/min) using a three dimensional motion analysis system (CMS70P). At the same time, peak plantar pressure was investigated using pressure distribution platforms (MatScan system) under the hallux heads of the first, second, and third metatarsal bones and heel. Maximal dorsiflexion and excursion and excursion at the ankle joint decreased significantly with increasing walking speed. Peak plantar pressure increased significantly under the heads of the first of the first, second, and third metatarsal bones, and heel with increasing walking speed: three was no change under the hallux. There were no significant changes in maximal dorsiflexion or excursion at the first metatarsophalangeal joint. The results show that walking speed should be considered when comparing gait parameters. The results also suggest that slow walking speeds may decrease forefoot peak plantar pressure in patients with peripheral neuropathy who have a high risk of skin breakdown under the forefoot.

Aim: The study aim was to determine the frequency with which women decline clinicians' treatment recommendations and variations in this frequency by age, cancer and service descriptors. Design: The study included 36,775 women diagnosed with early invasive breast cancer in 1998-2005 and attending Australian and New Zealand breast surgeons. Rate ratios for declining treatment were examined by descriptor, using bilateral and multiple logistic regression analyses. Proportional hazards regression was used in exploratory analyses of associations with breast cancer death. Results: 3.4% of women declined a recommended treatment of some type, ranging from 2.6% for women under 40 years to 5.8% for those aged 80 years or more, and with parallel increases by age presenting for declining radiotherapy (p<0.001) and axillary surgery (p=0.006). Multiple regression confirmed that common predictors of declining various treatments included low surgeon case load, treatment outside major city centres, and older age. Histological features suggesting a favourable prognosis were often predictive of declining various treatments, although reverse findings also applied with women with positive nodal status being more likely to decline a mastectomy and those with larger tumours more likely to decline chemotherapy. While survival analyses lacked statistical power due to small numbers, higher risks of breast cancer death were suggested, after adjusting for age and conventional clinical risk factors, (1) for women not receiving breast surgery for unstated reasons (RR=2.29; p<0.001); and (2) although not approaching statistical significance $p{\geq}0.200$), for women declining radiotherapy (RR=1.22), a systemic therapy (RR1.11), and more specifically, chemotherapy (RR=1.41). Conclusions: Women have the right to choose their treatments but reasons for declining recommendations require further study to ensure that choices are well informed and clinical outcomes are optimized.

This study surveyed 146 obese elementary school children(94 male and 52 female) in Seoul, and measured height, body weight, degree of obesity, blood pressure, fasting blood sugar, serum lipid profiles and liver function. The hypertension was above 95 percentile depending on age and sex. and the hyperglycemia was defined as above 110mg/dl. The hypercholesterolemia and hypertriglyceridemia were defined as above 200mg/dl, 160mg/dl, repectively. The abnormal liver function was considered as elevated alanine aminotransferase(ALT>35IU/L)or aspartate aminotransferase(AST>35IU/L). The results were as follows: 1. The mean degree of obesity was $29.56\pm12.56\%$, and the percentage of overweight was $18.5\%$, mild obesity $41.1\%$, moderate obesity $35.6\%$, severe obesity $4.8\%$ respectively in surveyed children. 2. The systolic blood pressure was $108.34\pm13.73mmHg$, diastolic blood pressure was $67.46\pm8.27mmHg$. 3. FBS was $93.79\pm6.51mg/dl$. 4. Total cholesterol, triglyceride, ALT and AST were $183.34\pm31.38mg/dl$. $115.55\pm56.43mg/dl,\;24.08\pm18.42IU/L,\; 28.73\pm10.45IU/L,$ respectively. 5. The prevalence of complications was $47.2\%$ : hypertension$(13\%)$, hyperglycemia$(0.7\%)$, hypercholesterolemia$(23.3\%)$, hypertriglyceridemia$(17.1\%)$, and liver dysfunction$(21.9\%)$. In conclusion. childhood obesity is associated with various risk factors. Therefore, the aggressive approaches to successful prevention, early detection, and effective treatment of obesity in children are urgently required.

Although stress has been implicated to be a risk factor that can threaten physical and mental health, there have been no sufficient studies that analyze the different levels of stress among employees working in the different levels of the hospitals. We aim to identify the general characteristics of hospitals at different levels, to compare the stress levels among customer service representatives working in the tertiary care hospitals as well as acute general hospitals. In addition, we also wanted to analyze the relationship between the types of hospitals and the stress level. The work stress was measured using the Korean Occupational Stress scale. Study subjects' demographic characteristics and lifestyle factors were analyzed using analysis of frequency and multiple regression analysis. Our study revealed that the levels of medical facility were significantly associated with the levels of job stress(P=0.043), and the stress levels of employees working in the acute general hospital's medical facilities were higher than those who were working in tertiary care facilities. We also found that those with higher depression level tended to have higher job stress (P<0.001). Therefore, it is urgent to implement some kind of job stress interventions, especially in the acute general hospital's medical facilities. Moreover, further studies including social and policy research are necessary in order to analyze the overall impact of stress on physical and mental health and to reduce health inequalities among healthcare workers.

Background: To assess women's awareness from diverse sections of society in Delhi regarding various aspects of breast cancer (BC) - perceptions, signs and symptoms, risk factors, prevention, screening and treatment. Materials and Methods: Community-level survey was undertaken in association with the Indian Cancer Society (ICS), Delhi during May 2013-March 2014. Women attending BC awareness workshops by ICS were given self-administered questionnaires before the workshop in the local language to assess BC literacy. Information provided by 2017 women was converted into awareness scores (aware=1) for analysis using SPSS. Awareness scores were dichotomized with median score=19 as cut off, create more aware and less aware categories. Bivariate and multivariate analysis provided P-values, odds ratios (ORs) and 95% confidence intervals (CIs). Results: Broadly, 53.4% women were aware about various aspects of BC. Notably, 49.1% women believed that BC was incurable and 73.9% women believed pain to be an initial BC symptom. Only 34.9% women performed breast self-examination (BSE) and 6.9% women had undergone clinical breast-examination/mammography. 40.5% women had higher awareness (awareness score > median score of 19), which was associated with education [graduates (OR=2.31; 95%CI=1.78, 3.16), post-graduates (OR=7.06; 95%CI=4.14, 12.05) compared to ${\leq}$ high school] and socio-economic status (SES) [low-middle (OR=4.20; 95%CI=2.72, 6.49), middle (OR=6.00; 95%CI=3.82, 9.42) and upper (OR=6.97; 95%CI=4.10, 11.84) compared to low SES]. Conclusions: BC awareness of women in Delhi was suboptimal and was associated with low SES and education. Awareness must be drastically increased via community outreach and use of media as a first step in the fight against BC.
