Under the background of continuous promotion of community old-age, the importance of research on the"family" life style of oldage residential facilities has become increasingly prominent. Through field survey of different types of oldage residential facilities and questionnaire interviews, the shortcomings of the old-age residential facilities in Xi’an were compared and summarized, and the key elements of "family" life style of the old-age residential facilities were concluded, which mainly include urban community embeddedness, family structure elements, indoor furnishings and accompanying care system. The "family" life style of the old-age residential facilities can not only maintain the "kinship" living needs, but also conform to the new direction of promoting the "community" of the old-age residential facilities in China.展开更多

Methods: The convenience sampling method was used to investigate 256 reproductive-age cervical cancer patients using the general information questionnaire, Acceptance of Illness Scale, Reproductive Concerns After Cancer Scale, and Medical Coping Style Scale. Results: The total score of the acceptance of illness was (18.03 ± 3.24), and reproductive concerns were (57.02 ± 6.30), among reproductive-age cervical cancer patients. Multivariate analysis showed that age, number of children, income level, treatment method, level of reproductive concerns, and the yield and avoidance dimensions of medical coping style were the main influencing factors on patients’ level of illness acceptance (all P Conclusion: The acceptance of illness levels in reproductive-age cervical cancer patients was low to intermediate, and medical staff should timely identify high-risk groups and take preventive management measures based on influencing factors.展开更多

Monoecious fig species and their pollinating wasps are in conflict over the use of fig ovaries which can either produce one seed or one wasp. From observation on Ficus virens Ait., we showed that female flowers with outer layer of ovaries (near to the wall of syconium) had no significant difference from that with inner and interval layer of ovaries (near to the syconium cavity), in which most seeds and wasps were produced. This meant that fig tree provided the same potential resource for seed and wasps production. Observation indicated that there was usually only one foundress in syconium at female flower phase and no com- petition pollinators. Measurement of the style length of female flowers and the ovipositor of pollinators indicated that most ovaries could be reached by pollinator’s ovipositor. However, at the male flower phase, production of seeds was significantly more than that of wasps including non-pollinating wasps but there was no significant difference between seed and pollinating wasp production when without non-pollinating wasps produced. This result indicated that non-pollinating wasps competed ovaries not with seeds but with pollinating wasps for ovipositing. Bagged experiment showed that the sampling fig species was not self-sterile which was important for figs and wasps to survive bad season. Seed production in self-pollinated figs was not significantly different from total wasps in- cluding non-pollinating ones. This might be related with the weaker competition among wasps since bagged figs were not easy to reach by wasps from outside.展开更多

However, the causal effect relationship among these variables remains unclear. The purpose of this study was to determine the causal relationships among health and life conditions, socioeconomic status, dietary and lifestyle habits and three health-related dimensions in elderly urban dwellers in Tokyo, Japan. Of 16,462 eligible elderly individuals aged 65 years and older, 13,195 participants responded to the questionnaire survey conducted in September 2001 (a response rate of 80.2%). A follow-up survey was conducted in September 2004 and a total of 8162 survivors were followed until the end of August 2007 through the municipal resident's registry. Exploratory factor analysis defined five latent variables based on the 13 observed variables. From a cross-lagged effects variation model using structural equation modeling, causal relationships were analyzed using longitudinal data obtained at the 2001 and 2004 survey and the number of survival days between 2004 and 2007. After estimating a best-fit model, we discovered that health and life conditions were not determined by current dietary and lifestyle habits, which many studies showed. However, the conditions were more directly affected by three health-related dimensions three years earlier, and indirectly affected by educational attainment and previous annual income as well. The current model suggests that it might be of great importance for elderly individuals to emphasize the maintenance of psychological well being, physical activity, social communication and participation, as well as income, rather than focusing on improvements in diet and health-related lifestyles per se.展开更多
