Modern multi-site database applications are not only time-driven but also require efficient quality of services with no single-node failure. It might be ideally achieved using database replication techniques. The transactions, being a basic component of these applications, are more likely to miss their deadlines because of requiring unpredictably long time to access remote data items. The temporal validity of data is another issue requiring attention to be paid. To address these problems, a Cluster-Replicas with Efficient Distributed Lazy Update (CRED) protocol is proposed in this paper. The CRED protocol increases the chance of timely execution of transactions and data freshness in an unpredictable workload environment by utilizing the lazy replica update strategy. It reduces the negative impact of the burst workload with a marginal overhead of ensuring timely-updated replicas. The simulation results confirm that the CRED outperforms the ORDER protocol by up to 4%.

Vincentius Kristus Raja (KR) Main Clinic aims to serve patients effectively and economically in an effort to improve the quality of public health services, especially in Surabaya. This type of research is descriptive qualitative in the form of a case study, to assess the implementation of standard operating procedures at the Vincentius Kristus Raja Main Clinic. Relevant data collection was carried out using questionnaires distributed to personnel related to standard operating procedures. The results of the research study according to the questionnaire indicate that the operational implementation is in accordance with the standard operating procedures that have been set based on the policies of the leadership and the Vincentius Kristus Raja Main Clinic Foundation. Compliance with standard operating procedures is very important because standard operating procedures are guidelines or references for carrying out tasks and work in accordance with their functions. The conclusions and suggestions from this study are that although compliance with standard operating procedures is adequate, the Vincentius Kristus Raja Main Clinic needs to develop and improve the quality of services, especially better communication with patients, both new patients and patients who have been on treatment for a long time at the Vincentius Kristus Raja Main Clinic. Considering that there are now many new health clinics that can be competitors for the Vincentius Kristus Raja Main Clinic, there must be a good response to this phenomenon. The emergence of these new competitors requires the Vincentius Kristus Raja Main Clinic to be able to be competitive in order to face the existing competition by improving the quality and quality of service for patients.

The most common problem that the terminals face is inadequate infrastructure, long waiting times, delays, malfunctions, and unexpected problems due to which terminals are often congested for a long time, high costs, lack of expansion, etc. All this leads to reduced quality of services and the price increase for the user service. These problems do not occur only at the terminal of one type, but at all terminals. At present, the delays and uneconomical operations are unacceptable. Intermodal terminals are not immune to any of the above. In order to increase the service quality and to reduce the cost of transportation and transmission, all the bottlenecks in the process are detected and analyzed in the work. The identification and removal of the bottlenecks in the processes of transport and transfer from the initial to the final terminal increases the quality of services provided to customers. The quality of services includes shorter time of transport and transfer by using shorter routes as well as the acceptable price of the service itself.

Due to the increase in life expectancy, today, most women live in a state of estrogen deficiency for more than a third of their life time. According to the recent document on the stages of aging of the female reproductive system (the STRAW+10 working group), there are three main stages that include the reproductive period, the menopausal transition, and postmenopause. One of the most common manifestations of postmenopause is vulvovaginal atrophy or genitourinary syndrome, which leads to a dramatic decrease in the woman’s quality of life. Up to 45 % of postmenopausal women suffer from this disorder, and 80 % of them experience a negative impact on their quality of life. The main symptoms of vulvovaginal atrophy are dryness, itching, burning, and dyspareunia. Caution must be exercised in relation to “silent” atrophy, which is not manifested by subjective complaints of vaginal mucosa atrophy, and can only be visualized by colposcopy. According to the recommendations of the International Menopause Society (IMS), updated in 2016, therapy should be started before the atrophic changes become irreversible; the treatment should continue for a long time to maintain the achieved therapeutic effect. If no symptoms other than vulvovaginal atrophy are noted, local estrogen therapy is indicated. Estriol has advantages over other medications due to its lower affinity for estrogen receptors. In earlier studies as well as those updated here (2014–2018), estriol applied topically as a vaginal cream or vaginal suppositories, has a selective effect on the urogenital tract and practically does not interfere with the proliferation of the uterine endometrium. The confirmed efficacy and safety of estriol allow for its permanent use, beginning with the starting dose and then switching to the maintenance one.

Abstract When using various types of services, the customer may experience positive or negative situations, incidents. These incidents may affect the customer's satisfaction or dissatisfaction. Therefore, these incidents can be a source of very valuable information for the enterprise about the quality of the services it offers. The problem, however, is their analysis, because such incidents can affect different aspects of the service, but also, as mentioned earlier, can have a positive or negative impact on customer satisfaction. The Critical Incident Technique (CIT), often mentioned in the literature, can be used for such an analysis. With this method, it is possible to isolate situations that are typical of the negative and positive feelings of the customers, as well as to determine the frequency of their occurrence. The purpose of the papers was to analyze the quality of services offered by the chosen catering enterprise with use of CIT. The research took form of a direct interview with customers after delivery of the chosen service. Data obtained on this basis was analyzed: all incidents were first divided into groups and categories as well as positive and negative incidents, and then statistics for individual categories were presented. This research allowed to indicate the strengths and weaknesses of the research service, but at the same time to indicate the areas of potential improvement.

Green spaces in cities perform many different useful functions: noise-proof, dust-absorbing, have an impact on the processes of insolation, they enrich the air with phytoncides, and also play a huge aesthetic role, which has a beneficial effect on the psychological state of people. In matters of planning and improvement of various objects, much attention is paid to landscaping. Green spaces can be used in planning and architectural solutions. Therefore, it is necessary to take a more careful approach to gardening and landscaping. This is especially true for objects where children are staying for a long time. This object is the Palace of creativity of children and youth of the city of Voronezh, the territory of which served for research. Such objects must be maintained in an appropriate sanitary and aesthetic condition, which will improve the quality of perception of the territory. Unsettled areas of institutions have a negative impact on the mood and General well-being of children and their parents, and may also contain a potential danger to the person at the time of stay. In particular, the unsatisfactory condition of plantings, roads, and small architectural forms is dangerous. Therefore, it is necessary to assess the state of the territory and recommend measures for landscaping and improvement, taking into account the requirements, as well as to develop an architectural and planning solution. As a result, a landscape and environmental assessment was performed, which consists in determining the type of spatial structure, assessing the state of plantings, aesthetic and sanitary assessments, the stage of digression, and recreational capacity. Based on the results of the study, functional zoning was developed. The balance of the territory was determined and it was found that the percentage of greenery does not meet the required standards. The condition of the plantings on the site was assessed as satisfactory. Therefore, it is necessary to Supplement the number of plantings with the most stable types of tree and shrub vegetation, taking into account their decorative and aesthetic value.
