But there occur Middle Barremian-Early Albian Aucellina(bivalvia) fossils in the Upper Yunshan Formation of the Longzhaogou Group and the Lower Chengzihe For-mation of the Jixi Group, and the Qihulin Formation of the Longzhaogou Group yields Early Cretaceousbivalve and ammonite fossils. Consequently, the geological ages of the two groups are mainly, or even all, Ear-ly Cretaceous.展开更多

This paper proposes two new approaches for the assessment of the weights to be associated with fuzzy opinions. These approaches involve,respectively,the minimization of the sum of squared differences between the individual weighted fuzzy opinion and the weighted mean value of all fuzzy opinions,which is called the weighted minimum variance method (WMVM),and the minimax difference of any two adjacent individual weighted fuzzy opinions,which is called the mean value minimax differences method (MVMDM). The two approaches are developed and numerical examples are presented to illustrate their simplicity and effectiveness in aggregating fuzzy opinions.展开更多

Material and Methods: The survey was conducted in May-June, 2012. In the course of the primary survey, one questionnaire was handed out to one in tenth of the newly arrived patients. Total number of 650 questionnaires was distributed. 563 respondents participated in the survey (feedback rate—86.6%). Statistical analysis of data was performed by means of personal computer using SPSS software package. Results: 54.7% of respondents state that they make use of the possibility of online registration with the family doctor. 85.05% of respondents indicate that a doctor, when making the next appointment or referring to the medical specialist, registers a patient on site by means of computer. Upon arrival of a respondent to the reception desk of the medical establishment, 90.3% of respondents are registered by means of computer. 72.4% of respondents say that they have a choice to telephone and inquire about the time of visit if they have forgotten the visit time or lost the appointment sheet. Majority of respondents using the online registration option belong to the age group between 21 and 40 years—35.3%. Conclusions: Answers by the respondents and the breakdown between “Centro poliklinika” and Seskine outpatient clinics are very similar and no essential differences have been determined.展开更多
