The confined concrete stress-strain curves utilised in computational models of concrete-filled steel tubular (CFST) columns can have a significant influence on the accuracy of the predicted behaviour. A generic model is proposed for predicting the stress-strain behaviour of confined concrete in short circular, elliptical and octagonal CFST columns subjected to axial compression. The finite element (FE) analysis is carried out to simulate the concrete confining pressure in short circular, elliptical and octagonal CFST columns. The concrete confining pressure relies on the geometric and material parameters of CFST columns. The post-peak behaviour of the concrete stress-strain curve is determined using independent existing experimental results. The strength reduction factor is derived for predicting the descending part of the confined concrete behaviour. The fibre element model is developed for the analysis of circular, elliptical and octagonal CFST short columns under axial loading. The FE model and fibre element model accounting for the proposed concrete confined model is verified by comparing the computed results with experimental results. The ultimate axial strengths and complete axial load-strain curves obtained from the FE model and fibre element model agree reasonably well with experimental results. Parametric studies have been carried out to examine the effects of important parameters on the compressive behaviour of short circular, elliptical and octagonal CFST columns. The design model proposed by Liang and Fragomeni (2009) for short circular, elliptical and octagonal CFST columns is validated by comparing the predicted results with experimental results.

Background: The rise in consumption of tobacco products among youth is a public health concern in India. Several studies have shown that advertisements promoting tobacco products influence decisions and behaviour of youth towards smoking. Objective: To ascertain which method of Tobacco Advertising, Promotion and Sponsorship (TAPS) was more influential for initiating tobacco use in youth in India. Materials and Methods: The secondary data of youth (15-24 years) from nationally representative Global Adult Tobacco Survey (GATS) conducted in 2009-2010 was analyzed. Odds ratio and p-value were used to know the association between TAPS and initiation of use of tobacco products among youth. Logistic regression was used to determine the most significant means of TAPS altering the youth's behaviour towards tobacco products. Results: Out of 13,383 youths, 1,982 (14.7%) used smokeless forms of tobacco and 860 (6.38%) used smoke forms. Logistic regression reveals that promotional activities mainly through cinemas (p<0.05) and providing free samples of tobacco products (p < = .001) were most influential means of initiating consumption of tobacco products among youth. Conclusions: The smoking in youth is associated with watching advertisements particularly in cinema and promotional activities like distribution of free samples, coupons and sales on the price of tobacco products. Stronger legislative measures should be enforced to curb promotional advertisements in cinemas and distribution of free samples.

Background: A behavior-based safety initiative card-issuing system was introduced at a cement-manufacturing company in Zimbabwe in 2008 to try and curb accident occurrence. The purpose of this study was to evaluate the effectiveness of the Behaviour Based Safety Initiative card system as a tool used for reducing accident frequencies. Methods: A mixed-method approach that involving administering piloted questionnaires to 40 out of 244 randomly selected employees, making observations, and reviewing secondary data were done to collect data from different sources in the organization in 2013. A paired t-test was conducted to test whether there was significant difference in accident occurrence before and after the implementation of the BBSI. Scatterplots were also used to establish the correlation between the issuance of cards and the accident and injury occurrence. Results: The findings suggest that the introduction of the card system brought a significant decrease in accident and injury occurrence. A negative correlation between card issuance and accident occurrence was observed, i.e., the greater the number of cards issued, the fewer the number of accidents. It was also noted that the card system positively influenced the mindset of workers towards safe work practices. Conclusion: The card system had an influence on the reduction of accidents and injuries. The organization should leverage on issuing more cards to further reduce the number of accidents and injuries to zero.

Objectives: After many national physical activity guidelines have established, recent changes are deep and rapid. So the major features and implication to reverse worsening Korean physical activity indicator is desprate but related knowledge and informations are few. So review of recent features and implications of new physical activity guidelines have made. Methods: National physical activity guidelines of advanced countries were searched through snowballing methods. Major features were described according to the nation. Implication were drew through discussion for Korean realitiy. Results: New Australian physical activity and sedentary behaviour guideline explicitly included sedentary behaviour. The age in the guideline expanded to early years. Canada also presented 24-hour movement guidelines to early years. The second generation of the physical activity guidelines reflects the extensive amount of new knowledge. New aspects include discussions of additional health benefits related to brain health, additional cancer sites, and fall-related injuries; immediate and longer term benefits for how people feel, function, and sleep; further benefits among older adults and people with additional chronic conditions; risks of sedentary behavior and their relationship with physical activity; elimination of the requirement for physical activity benefits to occur in bouts of at least 10 minutes; and tested strategies that can be used to get the population more active. Conclusions: The most important message from the new guidelines is that the greatest health benefits accrue by moving from no, to even small amounts of, physical activity. Multiple studies demonstrate that the steepest reduction in disease risk occurs at the lowest levels of physical activity. People need to understand that even small amounts of physical activity are beneficial and that reductions in the risk of disease and disability occur by simply getting moving. So various evidence based proven strstegies are needed in Korea including workforce training.

This study was performed to investigate the interrelationship between fasting serum insulin, eating behaviour, daily energy intake and the fatness in obese and non-obese women. The possibility of fasting serum insulin as potential predictive factor for eating behaviour and daily energy intake was also investigated. The results are as follows: 1) In obese women ; Subjects with higher fasting serum insulin were associated with higher speed of eating and shorter meal duration time. No association could be found between daily energy intake or the degree of obesity and fasting serum insulin. There was a significant positive correlation between obesity, daily energy intake and speed of eating. Obesity, daily energy intake were negatively related to meal duration time. Subjects with a rapid speed of eating were apt to overeat during eating behaviour experiment. Our findings suggested that a rapid speed of eating is a contributing factor to the development of obesity in obese women. 2) In non-obese women ; While subjects with higher insulin level were apt to overeat, we could not find any relation between overeating and daily energy intake. There was no correlation between eating speed and daily energy intake, but a significant positive correlation was found between meal duration time and daily energy intake. The degree of fatness was increased with the lower daily energy expenditure per body weight, or the higher waist hip girth ratio, fasting serum insulin and daily energy intake.

Purpose: To determine the biological behaviour of common odontogenic cystic lesions by analysing and comparing bcl-2 expression amongst them. Materials and Methods: Our study covered 90 formalin fixed paraffin embedded tissue samples: 26 primary cases each of radicular cysts (RC), dentigerous cysts (DC) and odontogenic keratocysts (OKC) and 12 of recurrent OKCs. Bcl-2 expression was analysed immunohistochemically and data analysis was accomplished using SPSS version 17.0. Means were taken for age while for gender and site of the lesions frequencies and percentages were determined. The Chi-square test was applied to evaluate any statistically significant difference of bcl-2 expression in these lesions and p value of ${\leq}0.05$ was taken as significant. Results: All the recurrent OKCs showed a strong positivity for bcl-2 that was absent in all of its primary cases (p value<0.05). Although variation in expression of bcl-2 was not found to be statistically significant between RC and DC, however, it became significant when all primary cases of these common odontogenic lesions were compared. Conclusions: Recurrent OKC showed comparatively a more aggressive behaviour than their primary counterparts and also from RC and DC. Bcl-2 proved to be a valuable adjunct in determining aggressive biological behaviour of odontogenic lesions.

This qualitative research on women in multi-cultural families aims to analyze their clothing weight, habit, management and purchasing of clothing as well as their children's in order to provide fundamental data or literature for their adjustment in Korean clothing culture and health management. The research was conducted by interviews to eleven married foreign women with nationality of various climates, and subsequently by categorical analysis and subject analysis. The final outcome in terms of subjects included 'heating/cooling system as to environmental temperature', 'scope of climate adaptation differences in the amount of clothing', 'sleepwear and bedding' and 'clothing purchasing behaviour'. The empirical survey showed that those who came from colder regions or warmer regions had difficulties adjusting to the climate. And their clothing weight & clothing habits, originated from their home countries, were found to be kept stable and to be systematically transferred to their children as well. When it comes to sleepwear and bedding, the women seemed to be less interested in them than normal outerwear, but they tended to like to cover the belly of their babies while they didn't have sufficient nightwear for themselves. And shopping and management of clothing were another area with differences between those women and Korean ones. These results imply that further research on the multicultural families, in particular on their clothing behavior, and on changeability of the behaviour through education or through evolution is needed.

Background: This study was conducted with the purpose of evaluating the effect of skin cancer training provided to maritime high school students on their knowledge and behaviour. Materials and Methods: The study had a quasi-experimental design with pre-test and post-test intervention and control groups. Two maritime high schools located in the city of Antalya were included within the scope of the study between March and June 2013, covering a total of 567 students. Results: While the knowledge mean scores of students regarding skin cancer and sun protection did not vary in the pre-test ($6.2{\pm}1.9$) and post-test ($6.8{\pm}1.9$) control group, the knowledge mean scores of students in the experimental group increased from $6.0{\pm}2.3$ to $10.6{\pm}1.2$ after the provided training. Some 25.4% of students in the experimental group had low knowledge level and 62.2% had medium knowledge level in the pre-test; whereas no students had low knowledge level and 94.3% had high knowledge level in the post-test. It was determined that tenth grade students, those who had previous knowledge on the subject, who considered themselves to be protecting from the sun better, had higher knowledge levels and their knowledge levels increased as the risk level increased. It was found that the provided training was effective and increased positively the knowledge, attitude and behaviour levels of students in the experimental group in terms of skin cancer and sun protection. Conclusions: Along with the provided training which started to form a lifestyle, appropriate attitudes and behaviours concerning skin cancer and sun protection could be brought to students who will work in outdoor spaces and are members of the maritime profession within the risk group.

Background: Breast cancer is the commonest type of cancer among women, and in Malaysia 50-60% of the new cases are being detected at late stages. Do age, education level, income, ethnicity, relationship with breast cancer patients and knowledge of breast cancer risk factors influence breast screening practices? This study revealed interesting but significant differences. Objectives: To assess the knowledge of breast cancer risk factors and early detection measures among women in a high risk group. Materials and Methods: A cross sectional survey of one hundred and thirty one women relatives of breast cancer patients was carried out. Participants were selected through purposive sampling, during hospital visits. A self-administered questionnaire was used for data collection. Results: The majority of the respondents (71%) had poor knowledge of the risk factors for breast cancer. Income, relationship with a patient and practise of breast cancer screening predicted performance of mammography, $R^2$=0.467, F=12.568, p<0.0001. Conclusions: The finding shows inadequate knowledge of breast cancer risk factors and poor cancer screening practise among women with family history of breast cancer. Poor knowledge and practise of breast screening are likely to lead to late stage presentation of breast cancer disease. Some important predictors of breast cancer screening behaviour among women with positive family history of breast cancer were identified. An understanding of the strengths and significance of the association between these factors and breast screening behaviour is vital for developing more targeted breast health promotion.

This study was to investigate knowledge, attitude and the preventive behaviour of noise of workers exposed to harmful noise and to provide primary data for noise-exposed workers' hearing conservation and the prevention of noise induced hearing loss. Method: The subjects were 104 workers who participated voluntarily in the questionnaire. The instrument used in this study was knowledge, attitude and practice on noise-induced hearing loss tool by Rhee & Yi (1996). The data were collected from August to September, 2002 with a self-administered questionnaire. Data were analyzed by SPSS 10.0 win program for finding frequency, percentage, mean, standard deviation, t-test, and ANOVA. Results: The average age of workers was 35.9 and the current average year of working at the noise place was $5{\sim}$10 years. In the group of previous noise-exposed workers, they showed significant difference in preventive behaviors (t=4.087, p=.048). In the group of current noise-exposed workers, they showed significant difference in recognition and attitude of noise(F=4.707, p=.004). Also, the duration of wearing ear protection equipment(t=2.383, p=.019), the feeling of wearing ear protection equipment(F=3.602, p=.031) and comfortable sense of wearing ear protection (F=3.919, p=.023) was significant in the preventive behaviour of noise. Conclusion: Considering the results above, we can recognize that there are close relations among the knowledge, attitude and the preventive behaviour of noise. Therefore, it is necessary to develop education - programs for noise-exposed workers' better understanding of noise and preventive behaviors
