  • In this paper, a gaze estimation method is proposed for use with a large-sized display at a distance. Our research has the following four novelties: this is the first study on gaze-tracking for large-sized displays and large Z (viewing) distances; our gaze-tracking accuracy is not affected by head movements since the proposed method tracks the head by using a near infrared camera and an infrared light-emitting diode; the threshold for local binarization of the pupil area is adaptively determined by using a p-tile method based on circular edge detection irrespective of the eyelid or eyelash shadows; and accurate gaze position is calculated by using two support vector regressions without complicated calibrations for the camera, display, and user's eyes, in which the gaze positions and head movements are used as feature values. The root mean square error of gaze detection is calculated as $0.79^{\circ}$ for a 30-inch screen.

  • There are two forms of medicine that have existed over time and are important in the delivery of expert health care. The forms of medicine are traditional and modern medicine. This study was aimed at assessing the awareness and perspective on the use and integration of traditional and modern medicine in a rural area of Sokoto State, Nigeria. Two hundred and seventy-one (271) respondents were recruited and a self-administered questionnaire on the awareness and perspective on use and integration of traditional and modern medicine was used to assess the participant's view. Among the participants, 200(73.8%) were females. The mean±SD age of respondents was 30.55±9.73 years. 80.8% of the respondents were aware of traditional medicine while 100% were aware of modern medicine. All respondents prefer modern medicine but about 28.8% support integration of both healthcare services. The results were considered significant when p-value was less than 0.005. There is a statistically significant relationship between the integration of traditional and modern forms of medicine and age, gender, religion, education, ethnicity and occupation but not for marital status. Though all the respondents preferred modern medicine to traditional medicine, some people still feel it will be good to combine both for a better healthcare system.

  • This study was conducted to identify the caregiver's educational needs for health care of children with intellectual disability in Mongolia. Data were collected from 150 family caregivers of children with disability in Mongolia between September 30 and October 31, 2017. The questionnaire included a scale for health care education needs in the form of 10 categories, 35 items, 5-point Likert's type. The mean score of educational needs of the primary caregiver were $4.05{\pm}0.65$. The category of information and knowledge acquisition showed the highest score ($4.48{\pm}0.57$). There were statistically significant differences in educational needs of the caregiver according to monthly income (F=7.07, p<.001), presence of a secondary caregiver (t=-2.70, p=.008), other disabled children status (t=2.02, p=.046), occupation status of disabled child's mother (F=3.87, p=.023), and multiple handicaps of caring child (t=-2.60, p=.010). The findings on caregiver's educational needs in this study can help inform planning of caregiving support services for children with intellectual disability in Mongolia.

  • This study was conducted to investigate the correlation between diabetes empowerment, health perception, and diabetes self-care behaviors with diabetes for the elderly in the community, and to identify the factors affecting diabetes self-care behavior in the elderly with diabetes. A survey was conducted on 80 diabetic elderly people over the age of 65 who were registered at a local public health center. The mean age was 71.15 years, and 41 males and 39 females were included. Diabetes self-care behavior showed a significant positive correlation with economic status (r=.245, p=.029) and diabetes empowerment (r=.406, p<.001), but health perception (r=.127, p=.263) did not show a significant correlation. As a result of this study, diabetes empowerment and economic status of the diabetic elderly were found to be significant influencing factors on diabetes self-care behavior in the diabetic elderly, and the explanatory power of the model was 19.6% (F=10.623, p<.001). Therefore, if a community program is developed to improve the diabetes empowerment of the elderly with diabetes in the community and economic support policies are also provided at the level of public health, it will be possible to improve the self-care behavior of the elderly with diabetes in the community.

  • The purpose of this study was to identify the moderated effects of emotional intelligence on the relationship between transition shock and adaptation on clinical practice among nursing students. Subjects were 185 associate nursing students associate nursing students(3rd). The data were collected using self -report questionnaire from May 1 to June 14, 2019. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson correlation and hierarchical multiple regression with SPSS/WIN 23.0. Mean point of transition shock(4 point scale) was 2.32. Mean point of emotional intelligence(5 point scale) was 3.61, and adaptation on clinical practice(5 point scale) was 3.40. Transition shock were significantly negative correlation with emotional intelligence(r=-.26. p <.001) and adaptation on clinical practice(r=-.43. p <.001) in nursing students. Emotional intelligence were significantly positive correlation with adaptation on clinical practice(r=.36. p <.001). Emotional intelligence has been shown to modulate the relationship between transition shock shock and adaptation on clinical practice(${\Delta}R^2=0.21$, p <.001). Therefore, to decrease the transition shock and to increase the adaptation on clinical practice of nursing students, It is necessary to develop the program for increase emotional intelligence of nursing students.

  • This article presents Bayesian approach to regression splines with knots on a grid of equally spaced sample quantiles of the independent variables under functional measurement error model.We consider small area model by using penalized splines of non-linear pattern. Specifically, in a basis functions of the regression spline, we use radial basis functions. To fit the model and estimate parameters we suggest a hierarchical Bayesian framework using Markov Chain Monte Carlo methodology. Furthermore, we illustrate the method in an application data. We check the convergence by a potential scale reduction factor and we use the posterior predictive p-value and the mean logarithmic conditional predictive ordinate to compar models.
