PURPOSE OF REVIEW: To examine the role of two nutritional factors implicated in the healthy aging of the Okinawans: caloric restriction; and traditional foods with potential caloric restriction-mimetic properties. RECENT FINDINGS: Caloric restriction is a research priority for the US National Institute on Aging. However, little is known regarding health effects in humans. Some caloric restriction-related outcomes, such as cause-specific mortality and lifespan, are not practical for human clinical trials. Therefore, epidemiological data on older Okinawans, who experienced a caloric restriction-like diet for close to half their lives, are of special interest. The nutritional data support mild caloric restriction (10-15%) and high consumption of foods that may mimic the biological effects of caloric restriction, including sweet potatoes, marine-based carotenoid-rich foods, and turmeric. Phenotypic evidence is consistent with caloric restriction (including short stature, low body weight, and lean BMI), less age-related chronic disease (including cardiovascular diseases, cancer, and dementia), and longer lifespan (mean and maximum). SUMMARY: Both caloric restriction and traditional Okinawan functional foods with caloric restriction-mimetic properties likely had roles in the extended healthspan and lifespan of the Okinawans. More research is needed on health consequences of caloric restriction and foods with caloric restriction-mimetic properties to identify possible nutritional interventions for healthy aging. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins.

This paper theoretically analyzes the so-called paradox of choice, introduced by Schwartz (The paradox of choice: why more is less, Harper Perennial, New York, 2004), which posits that having too many choices can make us unhappy. Although one’s possibilities broaden as the number of choices increases, the paradox of choice occurs because among a greater number of possibilities, making the best choice entails a greater number of complications and incurs higher choice costs. The purpose of this paper is to focus on a specific example of this paradox with respect to consumer nonpurchase behavior, in order to derive the optimal strategy for a firm selling goods or services for consumer purchase. In particular, in constructing a decision-making model by which to ascertain the optimal product quantity (variety) for a firm within the context of the paradox of choice, we can derive the number of product offerings needed to maximize sales. We point out that it is important for a firm to consider nonpurchase behavior. The optimal quantity is inversely proportionate to the consumer’s complications and choice costs in making a choice. © 2014, Springer-Verlag London.

Objectives. We analyzed the Japan's walking-to-school practice implemented in 1953 for lessons useful to other cities and countries. Methods. We reviewed background documents (gray literature, online government information, local policy documents, and regulations) for existing regulations in several urban settings. We also contacted boards of education. Results. Each municipality has a board of education in charge of public schools, which considers the geography, climate, and the transport situation to determine the method of commuting. Because there is high availability of schools in urban areas and most are located within walking range of the children's homes, walking is the most common method. There are different safety initiatives depending on the district's characteristics. Parents, school staff, and local volunteers are involved in supervision. Conclusions. The walk-to-school practice has helped combat childhood obesity by providing regular physical activity. Recommendations to cities promoting walking to school are (1) base interventions on the existing network of schools and adapt the provision to other local organizations, (2) establish safety measures, and (3) respond specifically to local characteristics. Besides the well-established safety interventions, the policy's success may also be associated with Japan's low crime rate.

This paper proposes a new placement method for two dimensional rectilinear polygons. The proposed method is based on the idea of corner junction method and uses only genetic algorithm approach with a new chromosome structure to pack rectilinear polygons onto container. The proposed method is implemented by enhancing the double chromosome structure to a hierarchical chromosome structure. It is a novel approach for solving the layout problem of rectilinear polygons using only genetic algorithm. Experimental results show the proposed method is succeeded in placement of some complicated two dimensional rectilinear polygons in feasible time. © 2011 IEEE.

In this paper, an innovative method is proposed for solving the two-dimensional rectangle packing problem by utilizing the Corner-Junction method (CJ method) introduced here for conjoining rectangular corners, enabling two adjoined rectangles to line up. Verification is accomplished through application of an evolutionary algorithm (EA), using the chromosome-structure also introduced. Some benchmark tests of the strip packing problem are shown to be solved by this EA, which enables 90-degree rotation of the rectangles. The experimental results show that use of the proposed CJ method provides satisfactory packing of rectangles but with quality in terms of gap varying 5-12% less than that of optimal solutions. The failure of EA to detect all viable solutions resulting from application of the CJ method is a consequence of the present sequential limitations of the proposed chromosome structure. ©2010 IEEE.
