The current study addresses the local buckling analysis of an infinite thin rectangular symmetrically laminated composite plate restrained by a tensionless Winkler foundation and subjected to uniform in-plane shear loading. An analytic method (i.e., one-dimensional mathematical method) is used to achieve the analytical solution estimate of the contact buckling coefficient. In addition, to study the effect of ply angle and foundation stiffness on the critical buckling coefficients for the laminated composite plates, the parametric studies are implemented. Moreover, the convergence for finite element (FE) mesh is analysed, and then the examples in the parametric study are validated by the FE analysis. The results show that the FE analysis has a good agreement with the analytical solutions. Finally, an example with the analytical solution and FE analysis is presented to demonstrate the availability and feasibility of the presented analytical method.

Corporate social responsibility (CSR) is of increasing interest to both industry practitioners and academics because of increasing public awareness of environmental, economic and social sustainability. The last decade witnessed a large number of studies on the development of CSR principles and the implementation of CSR in various industries such as the mining industry, oil industry and food industry. However, there is limited number of CSR studies focusing on the construction industry. Considering the critical role the construction industry plays in achieving economic, social and environmental sustainability, it is imperative to extend the current CSR research to the construction sector. This paper provides a critical review of literature related to corporate social responsibility in construction context. A special focus is placed on the current practice adopted by the industry to be socially responsible. A research agenda is set up to tackle this critical issue.

The purpose of this study to derstand the relationship between family support and self-esteem among middle-aged Korean women immigrants in Australia with a focus on the effects of depression, which seems to likely mediate these two variables. For the purpose of this study, 147 middle-aged Korean women who live and work in Sydney, Australia, were studied. A statistical method was carried out using descriptive statistics, correlation analysis and reliability analysis by using SPSS ver.18.0. To verify the hypothesis of the research model that was suggested in this study, with the structural equation, AMOS ver.7.0 program was used. The analytical results are as follows. Firstly, family support had an influence on depression and self-esteem and depression had an effect on self-esteem. Secondly, family support had an influence on self-esteem by having depression as a mediation. This outcome not only offers information on self-esteem, which is the psychological welfare of Korean middle-aged women who live in Australia, but also enhances the self-esteem of all middle-aged Koreanwomen who abroad, not just in Australia. Therefore, the study provide basic data support a program related to the welfare of immigrant women who live overseas along with policies for those immigrant women to have successful lives as immigrants. In addition to this, an exploratory research on relevant variables that influence self-esteem will have significant implications even to policies on multi-cultural families that have immigrate into South Korea.

Backgrounds/Aims: Gallbladder cancer (GBC) is a rare neoplasm. The epidemiology of GBC has not been updated in Australia for over five decades. Methods: Data of all Australian patients diagnosed with GBC at any age from 1982 to 2018 were identified from the Australian Cancer Database. Age-standardized rates were calculated and joinpoint analysis was performed to ascertain the trends of incidence and mortality of GBC. Results: Between 1982 and 2018, there were 22,745 cases of GBC and 11,054 GBC-related deaths in Australia. There were three distinct periods showing changed incidence. Period 1 (1982-1995) was stable. Period 2 (1996-2006) showed reduced incidence in females (3.6 to 2.8/100,000; p < 0.01) and all Australians (3.7 to 2.8/100,000, p < 0.01). Period 3 (2006-2017) demonstrated significantly increased incidence in all groups (males: 2.7 to 4.0/100,000, p < 0.01; females: 2.8 to 3.5/100,000, p < 0.01; all Australians: 2.8 to 3.7/100,000, p < 0.01). Incidence between females and males had declined from 1.10 : 1 in 1982 to 0.87 : 1 in 2017. There was a 71% reduction in mortality (3.1 to 0.9/100,000; p < 0.01). Median age at diagnosis increased from 69.7 to 74.3 years for females and from 67.2 to 73.3 years for males. Increasing incidence in the 6th to 8th decade of life in males, compared to previous years, was noted. Conclusions: Incidence, mortality, sex, and age of GBC have significantly changed in Australia since 1982. Rising incidence of GBC in Australia warrants further investigation.

Background: Previous studies generally indicate that synchronous bilateral breast cancers (SBBC) have an equivalent or moderately poorer survival compared with unilateral cases. The prognostic characteristics of SBBC would be relevant when planning adjuvant therapies and follow-up medical surveillance. The frequency of SBBC among early breast cancers in clinical settings in Australia and New Zealand was investigated, plus their prognostic significance, using the Breast Cancer Audit Database of the Society of Breast Surgeons of Australia and New Zealand, which covered an estimated 60% of early invasive lesions in those countries. Design: Rate ratios (95% confidence limits) of SBBC were investigated among 35,370 female breast cancer cases by age of woman, histology type, grade, tumour diameter, nodal status, lymphatic/vascular invasion and oestrogen receptor status. Univariate and multivariable disease-specific survival analyses were undertaken. Results: 2.3% of cases were found to be SBBC (i.e., diagnoses occurring within 3 months). The figure increased from 1.4% in women less than 40 years to 4.1% in those aged 80 years or more. Disease-specific survivals did not vary by SBBC status (p=0.206). After adjusting for age, histology type, diameter, grade, nodal status, lymphatic/vascular invasion, and oestrogen receptor status, the relative risk of breast cancer death for SBBC was 1.17 (95% CL: 0.91, 1.51). After adjusting for favourable prognostic factors more common in SBBC cases (i.e., histology type, grade, lymphatic/vascular invasion, and oestrogen receptor status), the relative risk of breast cancer death for SBBC was 1.42 (95% CL: 1.10, 1.82). After adjusting for unfavourable prognostic factors more common in SBBC cases (i.e., older age and large tumour diameter), the relative risk of breast cancer death for SBBC was 0.98 (95% CL: 0.76, 1.26). Conclusions: Results confirm previous findings of an equivalent or moderately poorer survival for SBBC but indicate that SBBC status is likely to be an important prognostic indicator for some cases.

Chemical composition of imported table salts from China (sun dried), Thailand (sun dried) and Australia (rock salt) were compared the mineral content and heavv metal contamination with Korean sun dried salt. Kimchies prepared by those salts were analyzed the quality by pH, acidity and sensory evaluation. Chemical compositions were as follows : moisturefrom 1.7% (Australia) to 8.7% (Korea), sodium chloride-from 86.7% (China, summer) to 97% (Australia), insoluble matter in water-from 0.02% (Australia) to 0.18 (China), and sulfate ionfrom 0.03% (Australia) to 1.65% (China, summer). Judging by Korean Standard(KS) of salt, salt from Australia and Thailand belong to 1st grade, Korean and Chinese (winter) to 2nd grade, and China (summer) were out of 3rd grade. Ca and Mg content of the salts tested were 0.022% (Australia) to 0.246 (China, winter), 0.036% (Australia) to 0.841% (China, summer) respectively and Pb was 1.23 ppm(China, summer)~0.61ppm(Korea) which is within the Korean regulation. The other heavy metals, Pb, Cd, As and Hg were not detected in all salts tested. The quality of Kimchi prepared by those salts were significantly no difference with Korean sun dried salt.

This study attempts to provide basic information on overseas employment to the radiological technologists and students majoring in radiology in Korea who consider the overseas employment by investigating the job consciousness for radiological technologists in Canada and Australia which have a high level of interest for overseas employment and want to compare their status with that of Korean radiological technologists. This study was performed by visiting hospitals such as Prince George Regional Hospital, 1475 Edmonton Street, Prince George, BC, Canada on August 13, 2007, Alfred Hospital, Commercial Road Melbourne 3004, Australia on August 4, 2008, and other Korea hospitals that show the similar scale as Canada and Australia on September 10, 2007. The results were summarized as follows : 1. Differences were observed in this sexual composition, such as 18 males (90%) in Korea, 14 females (73.7%) in Canada, and 25 females in Australia (86.2%). 2. The item of 'aptitude' which is one of the most important criteria, showed the highest level in Korea, Canada, and Australia, and the second most considered item was 'salary'. 3. In the values in jobs, the items of 'economic self-sufficiency', 'recognized by others', and 'establishing a social position' represented high levels in Korea, and the items of 'like the job itself', 'establishing self-actualization', 'feel the meaning of life', and 'make new friends' showed high levels in Canada and Australia. 4. Regarding the item of 'a job is important as much as a marriage', 'Yes' showed high level in Korea, and 'No' showed high levels in Canada and Australia. 5. Radiological technologists in Korea demonstrated a low level in the job consciousness compared to those of Canada and Australia. Although this study shows some limitations for showing whole idea of radiological technologists due to the lack of the scope in samples for each country as a practical manner, this study can be regarded significant to compare some countries that have interests in overseas employment.
