A growing number of studies are emphasizing the importance of positive and negative appraisals of caregiving and the utilization of social resources to buffer the negative effects of caring for persons with dementia. By assessing the roles of unmet needs and formal support, this study tested a hypothesized model for Korean family caregivers’ satisfaction and burden in providing care for persons with dementia.
Methods:
The stress process model and a two-factor model were used as the conceptual framework for this study. Data for 320 family caregivers from a large cross-sectional survey, the Seoul Dementia Management study, were analyzed using structural equation modeling. In the hypothesized model, the exogenous variables were patient symptoms, including cognitive impairment, behavioral problems, and dependency on others to help with activities of daily living and with instrumental activities of daily living. The endogenous variables were the caregiver's perception of the unmet needs of the patient, formal support, caregiving satisfaction, and caregiving burden.
Results:
The adjusted model explained the mediating effect of unmet needs on the relationship between patient symptoms or formal support and caregiving satisfaction. Formal support also had a mediating effect on the relationship between patient symptoms and unmet needs. Patient symptoms and caregiving satisfaction had a significant direct effect on caregiving burden.
Conclusion:
The level of unmet needs of persons with dementia and their family caregivers must be considered in the development of support programs focused on improving caregiving satisfaction.
To explore the relationship between children and their parents in terms of various anthropometric parameters and obesity-related hormone levels and to identify early indicators for child obesity.
Design
Cross-sectional observational study.
Setting
Urban areas of Korea in 2005.
Subjects
A total 124 families with 7-year-old children participated. Anthropometric and blood biochemistry data and information concerning the children’s lifestyles, dietary habits and parental and grandparental weight status were obtained.
Results
The mean values for all anthropometric parameters were greater in overweight children than in children of normal weight. Very close relationships existed between the anthropometric parameters of children and their parents. Children with two overweight parents showed the highest odds for being overweight (OR 7·62). The strong relationship between overweight children and grandparental and parental overweight, especially on the maternal side, suggests gender differences in the intergenerational transmission of body weight. We also noted a greater risk of being overweight in children with a parent with high serum leptin level.
Conclusions
Grandparental and parental weight status and parental serum leptin levels enable us to identify childhood obesity at an early age and may help to counter the current epidemic of adult obesity.
Plasma doping (PLAD) process utilizing PH3 plasma to fabricate n-type junction with supplied bias of −1 kV and doping time of 60 sec under the room temperature is presented. The RTA process is performed at 900 °C for 10 sec. A defect-free surface is corroborated by TEM and DXRD analyses, and examined SIMS profiles reveal that shallow n+ junctions are formed with surface doping concentration of 1021atoms/cm3. The junction depth increases in proportion to the O2 gas flow when the N2 flow is fixed during the RTA process, resulting in a decreased sheet resistance. Measured doping profiles and the sheet resistance confirm that the n+ junction depth less than 52 nm and minimum sheet resistance of 313 Ω/□ are feasible.
