Seniors Housing in a Changing Asian Society: South Korea

Traditionally, aging Koreans would live with their eldest son’s family. However, urbanization, economic expansion, and changing demographics are contributing to South Koreans considering alternative living arrangements. One possibility is the development of seniors housing, available only on a very limited basis today. This analysis indicates that a number of aging Koreans are interested in independent living, and many will soon have the economic resources to create demand for this type of housing. However, government policies would have to change for this product type to be developed successfully on a large scale.Seniors housing, Korea, consumer behavior, housing policy

Robust topology optimization of three-dimensional photonic-crystal band-gap structures

We perform full 3D topology optimization (in which "every voxel" of the unit cell is a degree of freedom) of photonic-crystal structures in order to find optimal omnidirectional band gaps for various symmetry groups, including fcc (including diamond), bcc, and simple-cubic lattices. Even without imposing the constraints of any fabrication process, the resulting optimal gaps are only slightly larger than previous hand designs, suggesting that current photonic crystals are nearly optimal in this respect. However, optimization can discover new structures, e.g. a new fcc structure with the same symmetry but slightly larger gap than the well known inverse opal, which may offer new degrees of freedom to future fabrication technologies. Furthermore, our band-gap optimization is an illustration of a computational approach to 3D dispersion engineering which is applicable to many other problems in optics, based on a novel semidefinite-program formulation for nonconvex eigenvalue optimization combined with other techniques such as a simple approach to impose symmetry constraints. We also demonstrate a technique for \emph{robust} topology optimization, in which some uncertainty is included in each voxel and we optimize the worst-case gap, and we show that the resulting band gaps have increased robustness to systematic fabrication errors.Comment: 17 pages, 9 figures, submitted to Optics Expres

In Support of the Care Bill: The Needs for Federally Mandated Minimum Education Standards in Diagnostic Medical Sonography

It is erroneously assumed that qualified professionals are performing diagnostic medical ultrasound procedures in medical facilities throughout the United States. To address this issue, the CARE bill has been proposed to the federal legislature. The bill’s primary intent is to mandate that medical facilities being reimbursed by the federal government for such diagnostic procedures comply with a minimum educational and training standard. Enactment of this legislation will create the need to provide the mandated education and training to a currently unknown number of individuals in a manner that is acceptable to standards compliance, as well as the employer and employee. A nationwide survey to identify demographics and educational backgrounds of this group as well as their employer’s perceptions related to necessary employee training/retraining is recommended

Fit Into College II: Physical Activity and Nutrition Behavior Effectiveness and Programming Recommendations

Purpose: To determine whether residency (living on campus versus off campus) was related to the effects of Fit into College on students’ health behaviors, and to understand interns’ perceptions of their roles in mentoring their trainees. Design: Pre-experimental, one-group, pretest-posttest design and a posttest focus group interview. Setting: University-offered health and internship courses. Subjects: Twenty-four students (trainees) participated in the intervention, nine of whom lived on campus. Five student-interns served as their mentors. Intervention: Fit into College was a 14-week intervention in which trainees teamed up with an intern to improve and/or maintain healthy nutrition and physical activity behaviors. Measures: Trainees’ nutrition and physical activity behaviors and perceptions were quantitatively assessed through surveys at preintervention and postintervention. Interns’ mentoring perceptions were qualitatively assessed through a focus group interview after the intervention. Analysis: Two-factor repeated measure ANOVAs and qualitative theme identification. Results: Regardless of their residency location, the trainees’ perceptions of the health benefits of eating fruits and vegetables improved during the intervention. However, for trainees living on campus, the intervention was not effective in increasing the number of fruits and vegetables consumed or the planning for food preparation. The interns perceived that they did not have adequate access to healthy foods, the knowledge or skills to prepare healthy foods, or the competency to teach food preparation strategies to their trainees. For trainees living on campus, the intervention was more effective in decreasing perceived exercise barriers than trainees living off campus. Conclusion: Future iterations of Fit into College may focus on 1) improving college students’ planning and preparation of healthy foods, 2) segmenting trainees into more homogeneous groups for the interns to tailor their areas of expertise (campus vs. off-campus and/or freshman vs. upperclass students), and 3) collaborating with university-partners to improve environmental conditions to promote physical activity and healthy nutrition

A Pilot Study for Plant the Seed: A Nutrition Education Program Using Local Food Environment to Put Theory into Action

The purpose of this study is to implement Plant the Seed, a garden-based nutrition education program designed to reconnect children with locally grown food, food environments of the past and present, and the benefits of eating seasonal foods. The pilot study investigates the environmental context and theory variables known to influence healthy food choice behavior. Social Cognitive Theory (SCT) provided a framework for the program’s curriculum and evaluation. The target audience is middle school students. Plant the Seed is a two-part program. In Part 1 (classroom), students participate in practical, interactive activities based on specific educational objectives that target theory mediators. In Part 2 (field trip), students rotate through the community farm, kitchen herb garden, and historic kitchen to engage in hands-on program activities. Pretest/posttest evaluation compared to control and intervention students from two schools measured program effectiveness. Intervention school students (n = 16) improved behavioral intention (3.40 vs 3.53, P = 0.34), historical social norm (3.40 vs 3.79, P = 0.03), and outcome expectations (3.91 vs 4.19, P = 0.03). No change in variables among control students (n = 10). Plant the Seed had a positive impact on factors associated with healthy eating behavior. This program demonstrates how to effectively engage community resources, to promote the development and implementation of gardening environments that create hands-on opportunities for children to become directly connected to local food production, to learn about the environmental benefits of eating locally grown foods and to allow children to have access to a positive, sustainable food environment. Plant the Seed can serve as a model for future theory and garden-based nutrition intervention programs

Research Brief No. 24 - (IN)Visible Minorities in Canadian Health Data and Research

This study examines the nature and extent of data and research on the role of race or visible minority status on health in Canada. Visible minorities represent a rapidly growing segment of Canada’s population. Approximately one in five Canadians is a member of a visible minority group. Policy makers and researchers are often unable to answer important questions related to visible minority health such as: Are visible minority Canadians healthier or less healthy than their white counterparts? Do risk factors for health conditions differ for visible minority and white Canadians? And how do different visible minority groups compare with one another on health outcomes and measures? Our review of the existing literature on visible minority health indicates that there is a paucity of data and research on the health of visible minorities in Canada, alone, and in comparison to ‘mainstream’ (white) Canadians. We recommend that there is a need for basic health data for visible minorities. Many current health surveys are severely limited by small sample sizes of visible minorities. We recommend oversampling visible minorities in standard health surveys such as the Canadian Community Health Survey, or conducting targeted health surveys of visible minorities. Surveys should collect information on key sociodemographic characteristics such as nativity, visible minority status, socioeconomic status, and age-at-arrival for immigrants. We also recommend that if data were available, researchers consider an intersectionality approach in their analyses. Intersectionality is a flexible holistic approach that takes into account the multiple factors that may affect a visible minority person’s health, including the role of discrimination based on racial status, immigrant characteristics for foreign-born visible minorities, age and the role of ageism for older adults, socioeconomic status, gender (for visible minority women), and geographic place of residence

(In)Visible Minorities in Canadian Health Data and Research

This synthesis project is motivated by the apparent neglect of visible minorities in Canadian health data and research. The main question is: Are visible minorities invisible in Canadian health data and research? To address this question, we assess the nature, extent, and range of data and research available on the health and health care access of visible minorities in Canada. Specifically, we summarize: (1) mortality and morbidity patterns for visible minorities; (2) determinants of visible minority health; (3) health status and determinants of visible minority older adult (VMOA) health; and (4) promising data sources that may be used to examine visible minority health in future research. While we reviewed a large number of publications, we note that only 5 examined population-­‐level data to specifically compare visible minorities with white Canadians and just 2 distinguished between Canadian-­‐born visible minorities and foreign-­‐born visible minorities. In addition, because of data and methodological limitations, and differences in topics examined, findings are not easily comparable to provide a clear picture of visible minorities’ health
