Background: Globally, the overall incidence of cancer is increasing as a result of ageing populations and changing lifestyles. Cancer is one of the leading causes of death, especially in the developed nations. Cancers affecting the young population are generally considered uncommon. This study assessed the demography and trends of cancers of the young in Brunei Darussalam, a small and developing Southeast Asia nation. Materials and Methods: All patients diagnosed with cancers between 2000 and 2012 were identified from the cancer registry maintained by the State Histopathology Laboratory. Cancers of the young was defined as any cancers diagnosed under the age of 40 years. Demographic data and the type of cancers were collected and analysed using SPSS Statistics 17.0. Results: Among the 6,460 patients diagnosed with cancer over the study period, 18.7% (n=1,205) were categorized as young with an overall decline in the proportion from 26.6% in 2000 to 18.8% in 2012 (p<0.001 for trend). Among all cancers of the young, the most common systems affected were gynecological (24.1%), hematological/lymphatic (15.8%), subcutaneous/dermatological/ musculoskeletal (10.5%), breast (10.5%) and gastrointestinal (9.9%). Overall, among the different systems, neurological (54.9%) had the highest proportion of cancers of the young followed by gynecological/reproductive (30.6%), hematological/lymphatic (39.9%), endocrine (38.7%), subcutaneous/dermatological/ musculoskeletal (22.3%) and the head and neck region (20.1%). There was a female predominance (66.9%) and the incidence was significantly higher among the Malays (20.1%) and expatriates (25.1%) groups compared to the Chinese (10.7%) and indigenous (16.8%) groups (p<0.001 for trend). Conclusions: Cancers of the young (<40 years) accounted for almost a fifth of all cancers in Brunei Darussalam with certain organ systems more strongly affected. There was a female preponderance in all racial groups. Over the years, there has been a decline in the overall proportion of cancers of the young. Selective screening programs should nevertheless be considered.

Although there has been a significant increase in breast-feeding (BF) rate in Korea, it is plateaued since 2008 and still low compared with that of other countries. Because BF has been related to lower obesity prevalence in many studies and the increase in childhood obesity became evident in Korea, we wondered if a relatively lower BF rate has anything to do with this increase. Therefore, we looked into the relationship between mode & duration of BF during infancy and weight status of toddlers using the data from Korea National Health and Nutrition Examination Survey 2008 through 2011. Number of 2-3 year old toddlers with complete information on BF, anthropometry and normal birth weight was 674. While 87% of them were ever-breastfed, 6.2% each of them were either obese or overweight based on the Standard Growth Chart for Korean Children. Not only the obesity prevalence was different among groups of different mode of feeding, but also the mean duration of BF was significantly longer in normal weight group (9.2 mo.) compared with obese group (5.5 mo.). Accordingly, overweight and obesity prevalence of the toddlers breast-fed for 12 months or longer was significantly lower than that of the toddlers breast-fed for less than 12 months (OR 0.53, 95% CI 0.32-0.87). This study revealed that both BF and duration of BF affect the childhood obesity and, BF for 12 months or longer should be encouraged more aggressively as one of the main strategies to prevent and/or decrease childhood obesity in Korea.

In recent, Korea introduced the local self-government system. And the local government tried to establish and implement plans for women. Those plans were established on the basis of not the particular environments of regional societies but similar policies of central government. Despite of geographical migrations, we can find differences of population structure and economic status among regions. As the result, most of regional policies for women were ineffective. This paper examines population structure and economic status of women by regions and recommends the long and medium direction for local policies for women. For analysis, it utilizes the 2% sample data-set of National Statistical Office's '1995 Population and Housing Census' in Korea. The findings of this paper are summarized as following; Firstly, the dependency rate of Chungchong-do, Cholla-do, Kyongsangnam-do will reach about 45% in 2000. Therefore, as soon as possible, those local government should establish the labor policies to enhance the economically active participation rate of the elderly persons and welfare policy for them. Secondly, the level of women's economic participation. Thus, local governments should set up labor market policies for women according to regional situations. For examples, in Kyonggi-do, Seoul, Daejeon, Daeku which unemployment rate of the highly educated women are relatively high, those local governments should seek the measures to tackle unemployment problem of them. Thirdly, due to the differences regional economic structure, women's employment structures differed also by region. Hence, local governments should formulate suitable plans to consider the working status of regional women's workers.

In the construction of high-rise buildings, bent re-bars are manually straightened to connect slabs to core-walls, which are usually cast before floor structures. During cold bending and straightening of re-bars, plastic deformation causing work hardening, Bauschinger effect and aging hardening is unavoidable. Tensile tests of coldly bent and straightened re-bars were conducted with test parameters of grade, diameter, and bend radius of re-bars as well as age between bending and straightening. Test results showed that proportional limits were lower and strain hardening occurred without yield plateaus. Inside and outside of re-bars with compression and tension deformations, respectively, during bending showed lower yield points due to Bauschinger effect and no yield plateaus due to work hardening, respectively. When re-bar grade was higher, yield point became significantly lower where Grade 400 re-bars had yield strengths lower than specified yield strength of 400 MPa. Because the surface of re-bar has higher strength than the core of re-bar, Bauschinger effect was more obvious for higher-grade re-bars. When age between bending and straightening was greater, yield strength increased and elongation decreased (i.e. embrittlement occurs). Using measured data, stress-strain relationship for straightened re-bars was developed based on Ramberg-Osgood model, which can be used to evaluate stiffness of joints when straightened re-bars are applied.

This study examined the relationship between social support, social participation and physical functioning among older adults in community senior centers. The subjects of this study were 194 persons aged 60 years or older who participated in the senior center in K province and D city, from June 16 to June 30, 2016. The collected data were analyzed using descriptive statistics, T-test, one way ANOVA, Pearson correlation analysis, multiple regression analysis, and structural model analysis using IBM SPSS Statistics 23.0 and IBM AMOS 21.0. The result showed that the social support and physical functioning of the elderly in the community were above normal, and social participation was somewhat low. Interestingly, an analysis of the physical functioning between social support, social participation and depression revealed significant correlations. The factors affecting the physical health were 23.4% of the respondents who had a significant influence on social support and leisure activities. In addition, the result of structural model analysis showed that social support had a significant influence on the social participation, depression and physical functioning. Therefore, the results suggests that the development of educational programs and an age-friendly environment should be actively provided to older adults in the community by strengthening the physical function through social support for active ageing.

This study aims to investigate the effect of psychosocial aging on age integration and the moderating effect of Familism and Family solidarity. In particular, this study has significance for establishing a basis of practical and political intervention in family level for improving age integration. We employed data from the 'Ageing Society Awareness Investigation' funded by Korean National Research Foundation in 2014. Our analysis sample consisted of 702 adults who were from 40 to 90 years old. Also, this study conducted descriptive statistics and multiple regression analysis by using STATA13. First of all, the lower psychosocial aging awareness is the higher age integration awareness. Familism and family solidarity were not a significant predictor for age integration. However, the interaction effects between familism as well as family solidarity and psychosocial aging ware statistically associated with age integration. That is to say that as psychosocial aging is negative, when decrease age integration, the net moderating effects of familism and family solidarity were found between age integration and psychosocial aging. Based on the results, this study provides implications that reinforcing family value and promoting interaction and solidarity with family members are positively contributed to age integration awareness at this point of negative psychosocial aging.

Considering the reality that the baby boom generation which takes up 15% of the Korean population enters the old age, this study aimed to investigate level and factors affecting successful aging of the baby boom generation. The theory this study used is Rowe & Kahn, and the data it used are from 2,577 persons combining respondents of the fifth basic survey and the special survey of Korean Longitudinal Study of Ageing. This study utilized IBM SPSS Statistics ver. 20.0 for analysis, and the main results of this study were as follows. First, successful aging level of the baby boom generation was $6.36{\pm}1.39$(range: 0~9), proving that they consider their aging as successful. However, depending on sub-factors of successful aging, proportion that they viewed themselves as successfully aging were quite different. Second, examination of factors affecting successful aging of the generation found out that pocket money, educational level, and child-parents relationship satisfaction are important. By applying the theory of Rowe & Kahn which can be called the representative model of successful aging, this study examined successful aging and extracted some suggestions for future researches.

Background: Cerebrovascular disease is included in four major diseases and is a disease that has high rates of prevalence and mortality around the world. Moreover, it is a disease that requires a high cost for long-term hospitalization and treatment. This study aims to figure out the correlation between grip strength, which was presented as a simple, cost-effective, and relevant predictor of cerebrovascular disease, and cerebrovascular disease based on the results of a prior study. And furthermore, our study compared model suitability of the model to measuring grip strength and relative grip strength as a predictor of cerebrovascular disease to improve the quality of cerebrovascular disease's predictor. Methods: This study conducted an analysis based on the generalized linear mixed model using the data from the Korea Longitudinal Study of Ageing from 2006 to 2016. The research subjects consisted of 9,132 middle old age people aged 45 years or older at baseline with no missing information of education level, gender, marital status, residential region, type of national health insurance, self-related health, smoking status, alcohol use, and economic activity. The grip strength was calculated the average which measured 4 times (both hands twice), and the relative grip force was divided by the body mass index as a variable considering the anthropometric figure that affects the cerebrovascular disease and the grip strength. Cerebrovascular diseases, a dependent variable, were investigated based on experiences diagnosed by doctors. Results: An analysis of the association between grip strength and found that about 0.972 (odds ratio [OR], 0.972; 95% confidence interval [CI], 0.963-0.981) was the incidence of cerebral vascular disease as grip strength increased by one unit increase and the association between relative grip strength and cerebrovascular disease found that about 0.418 (OR, 0.418; 95% CI, 0.342-0.511) was the incidence of cerebral vascular disease as relative grip strength increased by unit. In addition, the model suitability of the model for each grip strength and relative grip strength was 11,193 and 11,156, which means relative grip strength is the better application to the predictor of cerebrovascular diseases, irrespective of other variables. Conclusion: The results of this study need to be carefully examined and validated in applying relative grip strength to improve the quality of predictors of cerebrovascular diseases affecting high mortality and prevalence.

This study was to investigate depressive symptoms of caregiving grandmothers in South Korea and related factors focusing on caregiving characteristics. The data were drawn from the fourth wave of Korean Longitudinal Study on Ageing (KLoSA). The study participants were 3,291 grandmothers who had at least one grandchild, and we limited our analysis to 127 grandmothers who had provided care for their grandchild(ren) during the past one year. As for the depressive symptoms, Center for Epidemiological Survey-Depression 10(CES-D 10) short version were applied. Caregiving characteristics including caregiving duration by weeks per year, caregiving hours per week and the number of grandchildren who received grandmother care were examined. A multiple logistic regression was performed to detect association between caregiving characteristics and depressive symptoms while adjusting for general socioeconomic characteristics and health status of caregiving grandmothers. The longer duration of caregiving lowered the depressive symptoms and in contrast, those who spent more hours for providing care to their grandchildren were more exposed to the depressive symptoms. Physical pain significantly increased their depressive symptoms and low income level were more likely to induce depressive symptoms. More detailed studies on grandchild caregiving patterns among grandmothers were needed. Also, tailored support policy and services should be considered to alleviate their burden and depression in the future.

This study examined the moderating effect self-rated health has on the association between grandparenting and depressive symptoms. The fourth wave (in 2012) of the Korean Longitudinal Study of Ageing (KLoSA) was used for the analyses (N=650). The Coarsened Exact Matching (CEM) method was applied in order to ensure randomness in the selection of grandparents who participated in grandparenting and those who did not. The dependent variable was depressive symptoms, the independent variable was grandparenting, and the moderating variable was self-rated health. Control variables were education level, age, household income, gender, marital status and life satisfaction. After matching data by CEM, weighted multiple regression was applied with STATA 13.0. Also, simple slope analysis and region of significance were performed to interpret the interaction terms. The results showed that self-rated health had a significant moderating effect. Specifically, for grandparents with high self-rated health, grandparenting was associated with a lower level of depressive symptoms. On the contrary, for grandparents with low self-rated health, there was no difference depending on whether they participated in raising grandchildren. Based on these results, we discussed the need for consideration of self-rated health for grandparents who participated in grandparenting.
