Namibia has one of the highest HIV prevalence rates in the world. Older relatives in Namibia are taking the lead role in caring for children living with HIV, or orphaned as their parents had HIV. There has been a growing attention to the well-being and mental health of these older adult caregivers in sub-Saharan Africa; however, there is a lack of information on the intertwined factors such as loneliness and depression to their life satisfaction. Therefore, this study aimed to explore the relationship between loneliness and depression on life satisfaction among older caregivers of children living with HIV or AIDS in rural Namibia. This cross-sectional study recruited 100 Oshiwambo speaking caregivers over age 60 in the Omusati region to complete a study instrument measuring their levels of loneliness, depression and perceived life satisfaction. Using hierarchical regression method, this study found that both loneliness and depression were significantly associated with lower levels of perceived life satisfaction among our sample. Medical care or insurance and awareness of social services were both associated with higher levels of perceived life satisfaction. Social service professionals and policy makers in Namibia should consider designing culturally appropriate interventions aimed at addressing these important mental health related concerns of older rural caregivers.

A polyhedral oligomeric silsesquioxane (POSS)-based insulating material with photocurable propyl-cinnamate groups (POSS-CYNNAM) was designed and synthesized through simple single step reaction for use as a gate dielectric in organic thin-film transistors (OTFT). POSS-CYNNAM was soluble in common organic solvents and formed a smooth thin film after spin-casting. A thin film of POSS-CYNNAM was cross-linked and completely solidified under UV irradiation without the use of additives such as photoacid generators or photoradical initiators. ITO/insulator/Au devices were fabricated and characterized to measure the dielectric properties of POSS-CYNNAM thin films, such as leakage current and capacitance. A pentacene-based OTFT using the synthesized insulator as the gate dielectric layer was fabricated on the transparent indium tin oxide (ITO) electrode, and its performance was compared to OTFTs using thermally cross-linked poly(vinyl phenol) (PVP) as the insulator. The fabricated POSS-CYNNAM OTFT showed a comparable performance to devices based on the PVP insulator with 0.1 cm(2)/Vs of the field effect mobility and 4.2 x 10(5) of an on/off ratio. ; This work was supported by a National Science Foundation (NRF) grant funded by the Korea government (MEST) (No. 2011-0011122) through GCRC-SOP (Grant No. 2011-0030668). ; OAIID:oai:osos.snu.ac.kr:snu2013-01/102/0000029430/7 ; SEQ:7 ; PERF_CD:SNU2013-01 ; EVAL_ITEM_CD:102 ; USER_ID:0000029430 ; ADJUST_YN:Y ; EMP_ID:A076109 ; DEPT_CD:430 ; CITE_RATE:3.836 ; FILENAME:organic electronics 14, 2315 (sep, 2013).pdf ; DEPT_NM:전기·정보공학부 ; EMAIL:chlee7@snu.ac.kr ; SCOPUS_YN:Y ; CONFIRM:Y

The first of its kind, this book helps readers better understand Korean American mental health issues and their ongoing implications. The editors offer culturally competent practices, program developments, and policies that will better address the Korean Americans who are dealing with mental health issues.
