Dementia, characterized by a progressive cognitive decline and a cumulative inability to behave independently, is highly associated with other diseases. Various cardiovascular disorders, such as coronary artery disease and atrial fibrillation, are well-known risk factors for dementia. Currently, increasing evidence suggests that sex factors may play an important role in the pathogenesis of diseases, including cardiovascular disease and dementia. Recent studies show that nearly two-thirds of patients diagnosed with Alzheimer's disease are women; however, the incidence difference between men and women remains vague. Therefore, studies are needed to investigate sex-specific differences, which can help understand the pathophysiology of dementia and identify potential therapeutic targets for both sexes. In the present review, we summarize sex differences in the prevalence and incidence of dementia by subtypes. This review also describes sex differences in the risk factors of dementia and examines the impact of risk factors on the incidence of dementia in both sexes.

Four external and 22 cranial characters of 279 specimens representing 24 species of six orders of Korean mammals were measured. The data were analyzed by phenetic methods such as ordination as well as clustering techniques. Morphological distances were also calculated. Phenetic studies yield taxonomic placements of Siberian mink, Palearetic squirrel, and big white-toothed shrew which are incorrect. Morphological differences among Korean mammals at ordinal level in the taxonomic hierarchy are larger than those among other mammals: morphological differences below ordinal level are comparable to those among other mammals. Average taxonomic distances and morphological differences among Korean mammals at various levels in the taxonomic hierarchy are jointly monotonic, although the value of Pearson's product-moment correlation coefficient between average taxonomic distance matrix and morphological difference marrix is 0.59.

The purpose of this study was to investigate whether there are any differences in the recognition of the level of the guarantee of the rights of infants and toddlers according to the teachers' variables(gender, age, working experience) and institutional variables (institution type, establishment type, scale, area). We surveyed 365 special education teachers and found out differences. The results are as follows. First, there was no difference in the recognition according to gender. Second, there was no difference in the recognition according to age. Third, there was no difference in the recognition by working experience. Fourth, the recognition by type of educational institution showed that there were differences in the ambit of rights to life, protection, development, and participation. Fifth, the recognition according to the establishment type showed there were differences in the rights to life and development. On the other hand, there was no difference in the rights to protection and participation. Sixth, there were differences in the recognition about the rights to life, protection, development, and participation according to the scale of the education institutions. Seventh, there were no differences in the region. The results of this study can be used as basic data for establishing policy for the promotion of educational rights for infants with disabilities.

Our motivation in this note is to find equal hyperharmonic numbers of different orders. In particular, we deal with the integerness property of the difference of hyperharmonic numbers. Inspired by finiteness results from arithmetic geometry, we see that, under some extra assumption, there are only finitely many pairs of orders for two hyperharmonic numbers of fixed indices to have a certain rational difference. Moreover, using analytic techniques, we get that almost all differences are not integers. On the contrary, we also obtain that there are infinitely many order values where the corresponding differences are integers.

The clock frequency difference of sensor nodes is one of main parameters in TOF estimation and affect to degrade ranging algorithms to estimate positions of mobile nodes in wireless sensor networks. The specification of IEEE802.15.4a describes asynchronous TWR and SDS-TWR insensitive to frequency difference without any additional network synchronization. But the TWR and SDS-TWR can not eliminate sufficiently the effect of frequency difference of node pair, packet processing delay and its difference. Especially use of low cost oscillator with wide range offset, sensor node with different hardware and software can make the positioning errors worse. We propose an estimation method of frequency differences, and apply the measured frequency differences to TWR and SDS-TWR. We evaluate the performance of the proposed algorithm with simulation, and make certain that the proposed method enhances the performance of existing algorithms with positioning errors less than 25 cm.

This study examines the possible differences in satisfaction level according to the attributes classified as product, price, and service among women apparel consumers with the experience of buying global and domestic SPA brands. Data were collected through a survey of 270 women consumers aged 20s and with SPSS 15.0. The results are as follows: The exploration of the difference in product, price, and service attributes between the global and domestic SPA brands revealed that for product attributes, domestic brands scored higher in management quality, while global brands scored higher in design. In addition, for price attributes, domestic brands scored higher in promotion, while global brands scored higher in price value. When it comes to service attributes, only in regards to store policy was there a significant difference, with the score of global brands higher than domestic brands. The analysis of the difference in shopping orientation on domestic SPA brands showed significant difference only in customer convenience for the category of service attributes, while on global SPA brands, there were significant differences of the design for product attributes, promotion for price attributes, and customer convenience for service attributes.

The purpose of this research was to assess gender differences in the processes of intergenerational transmission of marital instability. This study revealed gender differences in the intergenerational transmission of marital instability. The fit indices suggest that the hypothesized model fit better for the female sample. Parental divorce marital quality and marital commitment were significant predictors of marital instability for both genders. Parental divorce was a strong predictor of marital quality for women only. While the path between age difference and marital quality for females was strong the same association disappeared for their male counterparts.
