Abstract As smartphones came into wide use recently, it has become increasingly popular not only among young people, but among middle-aged people as well. Most smartphones adopt capacitive full touch screen, so touch commands are made by fingers unlike the PDAs in the past that use touch pens. In this case, a significant portion of the smartphone's screen is blocked by the finger so it is impossible to see the screens around the finger touching the screen; this causes difficulties in making precise inputs. To solve this problem, this research proposes a method of using simple AR markers to improve the interface of smartphones. A marker is placed in front of the smartphone camera. Then, the camera image of the marker is analyzed to determine the position of the marker as the position of the mouse cursor. This method can enable click, double-click, drag-and-drop used in PCs as well as touch, slide, long-touch-input in smartphones. Through this research, smartphone inputs can be made more precise and simple, and show the possibility of the application of a new concept of smartphone interface.

The End Of History

We measured the personalities, values, and preferences of more than 19,000 people who ranged in age from 18 to 68 and asked them to report how much they had changed in the past decade and/or to predict how much they would change in the next decade. Young people, middle-aged people, and older people all believed they had changed a lot in the past but would change relatively little in the future. People, it seems, regard the present as a watershed moment at which they have finally become the person they will be for the rest of their lives. This “end of history illusion” had practical consequences, leading people to overpay for future opportunities to indulge their current preferences.

The aim of the study was features of ultrastructural changes in cellular elements and connective tissue carcass of the great saphenous vein (GSV) at varicose disease in depending on the duration of the disease in persons of different ages. An examination by light microscopy of 133 fragments of BPV, excised during phlebectomy in 19 patients, and an electron microscopic examination of 532 preparations were performed. Depending on the age of the patients, four age groups was distinguished: 18-44 years old (young people); 45-59 years (middle-aged people); 60-74 years old (the elderly), 75-90 years old (persons of senile age). In the wall of the GSV of young people with a small duration of the disease, there were poorly expressed pathomorphological changes characterized by moderately expressed endothelial dysfunction and minor hypertrophy of smooth muscle cells (SMC) of the middle shell. In the group of middle-aged people, in addition to age-related changes in the structure of the wall of varicose dilated GSV, pathological changes are noted that are characteristic of the long course of the disease with the development of endothelial dysfunction. The phenotypic heterogeneity of the SMC in the middle shell intensifies, and the communication links between them is altered. Disorganization of connective tissue leads to a decrease in the strength of the connective tissue vein skeleton. Hypertrophy of SMC, as a universal compensatory-adaptive response of cells, develops in response to an increase in functional load with hemodynamic disturbances in the veins of the lower limbs and to compensate for the quantitative deficiency of SMC as a result of their death. In elderly and senile age the duration of varicose disease is more than 10 years, on average - up to 25-30 years. The number of destructively altered SMC is increasing, degenerative processes and sclerotic changes are progressing. The ultrastructural analysis of biopsies showed that at the initial stage of development of varicose disease in young people with a small duration of varicose disease, morphological changes in the structure of the GSV wall are poorly expressed. With the increase in the age of the patient and the duration of the disease, changes in GSV are progressed. Involute degenerative-dystrophic changes are most pronounced in patients over 60 years of age and are an aggravating factor during varicose transformation of the GSV wall. In elderly and senile age, the compensatory possibilities of the cells decrease, the sclerotic degenerative changes in the wall of the GSV are progressed.

Prevention Of Dental Diseases

Recently, sanitary and educational work for the prevention of dental diseases in children is widely implemented, but the problem of awareness and oral hygiene in young and middle-aged people remains quite relevant. Nowadays, the range of dental items and hygiene products is quite wide, so a person who does not receive the recommendations of a dentist is quite difficult to understand what and why it should be used. Therefore, the aim of the study was to study the preventive knowledge of ordinary passers-by of young and middle age and their awareness of additional subjects and hygiene products. Object and methods of research. To achieve this goal, 100 passers-by in the center of Poltava were interviewed. According to the age classification of the World Health Organization: the young age is from 25 to 44, middle age is 44-60, elderly age is 60-75, senile age is 75-90 and long-livers are after 90. Two age groups were selected for the results: young and middle-aged, as these groups are the most common. Age was determined by survey. 50 people aged 25-44 years and 50 people aged 44-60 years were elected. The gender was not taken into account when choosing a contingent. Passers-by were asked 5 simple questions that characterized both the preventive habits of the respondents and knowledge about hygiene items and products. Research results and their discussion. Analyzing the answers to the questions, we found that young people (25-44 years) are more aware of the rules of oral care than middle-aged respondents (44-60 years). Answering the first question - "How often do you visit the dentist?" respondents answered as follows: only 5 young people visit the dentist as needed, while among middle-aged people this number is seven times higher. When answering the second question - "Do you pay attention to the composition of toothpaste when choosing?" respondents answered as follows: 42% of young people always pay attention to the composition, twice as many people - buy what the dentist advises, and the rest respondents were not interested in the components of the paste. The results of the second group were significantly worse. The third issue concerned the frequency of toothbrush changes, which is very important for the quality of oral hygiene and cleaning efficiency. The results of the survey showed that people from the older age group of the study are less aware of this issue. The answers to the fourth and fifth questions also showed a lower level of knowledge in middle-aged people. Thus, after analyzing the answers of the respondents, it is clear that people of the younger age group (25-44 years) are more aware of oral hygiene and prevention of dental diseases. In our opinion, this situation is associated with the introduction of health education at different levels, available information on the Internet and various social platforms, more responsible attitude to their health and awareness of preventive measures. It is necessary to pay attention to the education of middle-aged people regarding oral hygiene, as it is an integral part of the prevention of dental diseases.

58 patients with ischemic stroke were examined (29 young people — the main group and 29 middle-aged people — control group). Among the examined young patients, cardio embolic subtype of stroke prevailed (66 %), and among middle-aged patients was observed in 10 %. The athe rothrombotic subtype of stroke prevailed in middle-aged people (69 %), and among young people — 24 %. The lacunar subtype of stroke in young people was 3 %, and in middle-aged people — 21 %. Patients of young had such subtypes of strokes as hemodyna mic and hemorheological, which respectively equaled 3 %. In middle age these subtypes of strokes were not observed among the examined patients. In young people the proportion of vascular pools with ische mic stroke was: vertebrobasilar — 41 %, carotid prevailed to some extend — 59 %. In middle-aged people the proportion of strokes prevailed in the carotid pool — 64 %, in the vertebrobasilar it was 29 %. Middle-aged people also had a “combined stroke” (stroke that occurred in several pools at once), it amounted to 7 %. As a result, Doppler study of cerebral vessels proved that in young people linear velocity in the right middle cerebral artery was authentically higher compared with middle-aged patients. At the same time, the linear velocity in middle-aged patients was statistically greater in the left vertebral artery. Keywords: ischemic stroke subtypes, young age, hemodynamic parameters

Proprioceptive Inputs

Proprioceptive input may greatly affect postural stability. However, the proprioceptive postural strategy in elderly, middle-aged, and young people has not been investigated sufficiently. Hence, in this study, we aimed to investigate differences in proprioceptive postural strategies of elderly, middle-aged, and young people. The center of pressure displacement was determined in 23 elderly, 23 middle-aged, and 23 young people during upright stance on a balance board with their eyes closed. Vibratory stimulations at 30, 60, and 240 Hz were applied to the lumbar multifidus (LM) and gastrocnemius (GS) muscles to evaluate the contributions of different proprioceptive signals used in balance control. Compared with middle-aged and young people, elderly people showed a high dependence on postural control of the GS at 30 Hz (p-values: Young and elderly: 0.033; middle-aged and elderly: 0.001). Moreover, compared with young people, elderly people were more dependent on postural control of the LM at 240 Hz (p = 0.016). There were no significant differences with respect to the GS at 60 and 240 Hz, and with respect to the LM at 30 and 60 Hz between the elderly, young, and middle-aged people. Thus, the postural control strategy of elderly people depends on the GS at 30 Hz.

Background. We examined correlates of past year suicidal thoughts and behavior (STB) and described past year treatment experiences among young people who inject drugs (PWID). Methods. Participants were 570 adults (18-25 years) who injected primarily heroin. Interviews were conducted at field stations operated by Community Outreach Intervention Projects in Chicago, Illinois (USA). Interviewers administered the Psychiatric Research Instrument for Substance and Mental Disorders. Substance use and mental disorders were based on DSM-IV diagnostic criteria. Past year STB was based on multiple questions. Results. Sixteen percent of men and 25% of women reported STB in the past year. In multivariable analysis, STB was associated with non-heterosexual orientation, foster care, and being raised by two parents. Primary major depression, post-traumatic stress disorder, other anxiety disorders, and borderline personality disorder had independent effects on suicidality. Among those reporting past year STB (n=111), 83% ever received mental health treatment, while 44% did so in the past year. While 24% of respondents indicated that at least one treatment matched their needs very well, 30% reported treatment that did not match their needs at all. The most common reason for ending treatment was program completion (about 50%) while getting better was endorsed by about 25%. Nearly half reported ending treatment due to a bad experience, logistical issues, or expense. Conclusions. Young PWID are at high risk for suicidal behavior and their mental health treatment experiences often do not meet their needs. There is a pressing need for more integrated substance use and mental health treatment.

Success Of Treatment

Relevance. The success of treatment of periodontal diseases directly depends on the patient’s response to the therapy, therefore, the characteristics of the person’s personal characteristics can affect both the effectiveness of treatment and the prevention of relapse of the disease.Purpose. To study the features of the internal picture of the disease in the process of complex treatment of adult patients suffering from chronic generalized periodontitis.Materials and methods. The generally accepted comprehensive treatment of chronic generalized periodontitis in 69 middle-aged and elderly men was carried out taking into account the personal response of patients Solovyov «Psychosensory-anatomical-functional maladaptation syndrome».Results. When patients were discharged from the hospital, there was a difference in the phenomena of maladaptation among the elderly and middle-aged: in middle-aged people, sufficient adaptation to the conditions of existence was determined; in elderly people, due to the existing comorbid pathology, a state of maladaptation was diagnosed, which was caused by the presence of complaints of defects in the dentition.Conclusion. In elderly people, as soon as possible after completion of treatment in a hospital, dental rehabilitation cannot be considered completed, which requires the adoption of organizational measures for their timely provision of dentures.

AbstractThe novel coronavirus pneumonia (COVID-19) outbreak that emerged in late 2019 has posed a severe threat to human health and social and economic development, and thus has become a major public health crisis affecting the world. The spread of COVID-19 in population and regions is a typical geographical process, which is worth discussing from the geographical perspective. This paper focuses on Shandong province, which has a high incidence, though the first Chinese confirmed case was reported from Hubei province. Based on the data of reported confirmed cases and the detailed information of cases collected manually, we used text analysis, mathematical statistics and spatial analysis to reveal the demographic characteristics of confirmed cases and the spatio-temporal evolution process of the epidemic, and to explore the comprehensive mechanism of epidemic evolution and prevention and control. The results show that: (1) the incidence rate of COVID-19 in Shandong is 0.76/100,000. The majority of confirmed cases are old and middle-aged people who are infected by the intra-province diffusion, followed by young and middle-aged people who are infected outside the province. (2) Up to February 5, the number of daily confirmed cases shows a trend of “rapid increase before slowing down”, among which, the changes of age and gender are closely related to population migration, epidemic characteristics and intervention measures. (3) Affected by the regional economy and population, the spatial distribution of the confirmed cases is obviously unbalanced, with the cluster pattern of “high–low” and “low–high”. (4) The evolution of the migration pattern, affected by the geographical location of Wuhan and Chinese traditional culture, is dominated by “cross-provincial” and “intra-provincial” direct flow, and generally shows the trend of “southwest → northeast”. Finally, combined with the targeted countermeasures of “source-flow-sink”, the comprehensive mechanism of COVID-19 epidemic evolution and prevention and control in Shandong is revealed. External and internal prevention and control measures are also figured out.
