The article focuses on examining the influence of fluctuations in annual precipitation amount on the quality of surface waters. Water quality was estimated with data on BOD, COD and phosphate–ion concentration within five selected regions of Ukraine. Analysis of the precipitation data (1991 – 2010) showed different regional trends. Using the statistics, determination of the interconnection between precipitation amount and water resources quality were done. The obtained regularities and associated uncertainties can be used for prediction of changes in water resource quality and as a guide for future adaptation to possible climate change.

In this work we have studied the selection criteria for traffic analysis zones and the effects of their size and number on the model’s forecasting capabilities. To do so we have focused on the corridor of İstanbul’s Kadıköy-Kartal Metro Line and evaluated the consistency of demand forecasts and travel assignments versus actual measurements under different sizes of the Traffic Analysis Zones (TAZ). Significant improvements in model accuracy were observed by decreasing the zone size. Specifically, studying the public transport network assignments for the metro line when increasing the number of traffic analysis zones from 540 to 1,788 the root mean square error (RMSE) of forecasted vs. actual station-based counts was reduced by 23%. Subsequently, the study used population density and employment density as independent variables for the determination of the optimal radius for the 1,788 zone area, and applied an exponential regression model. Appropriate model parameters were derived for the above case study. The regression model resulted in R2 values over 0.62.

Continuing attempts to align science and technology policies with industrial and societal needs have aroused interest in the determination of research priorities. In this paper, we report a case study where leading experts from industry and public administration were assisted by multicriteria decision analysis in the planning of a collaborative research program for Scandinavian forestry and forest industries. We also address processual and methodological challenges in the deployment of multicriteria methods, and argue that such methods can contribute to the quality of decision support processes in related contexts.

Rate Calculation

Tariff of services at Kajen Public Hospital charged on general patients was calculated based on operational costs like cost of medical services, consumables, medicines, treatment class, and rental cost of surgery room. Unfortunately, all components of costs for tonsillectomy treatment had not been included. Determination of the tariff had not calculated indirectly costs. Tariff of tonsillectomy treatment at the Kajen Public Hospital at inpatient room based on a local regulation Number 1 year 2012 was Rp 3,275,000 for class 3 whereas tariff for claim of BPJS at the same class at a regional hospital type C was Rp 1,767,900. In this case, there was any difference between costs that had to be spent for tonsillectomy treatment and claim from BPJS. Each cost must be calculated in accordance with clinical pathway to determine unit cost in order to provide high-quality of services. The aim of this study was to figure out amount of unit cost based on clinical pathway on tonsillectomy diagnosis at the Kajen Public Hospital. This was an observational analytic study by conducting a case study at the Kajen Public Hospital. Clinical pathway was arranged through meeting of a drafting team. A calculation of unit cost was performed using a method of Activity Based Costing (ABC), determination of exceeding cost. The results of clinical pathway arrangement showed that steps of tonsillectomy diagnosis pathway were as follows: admission, diagnostic, therapy, and follow up. Unit cost of tonsillectomy diagnosis based on the ABC calculation was Rp 2,717,662. The results of cost recovery rate calculation demonstrated that CRR among general patients was 121% whereas among BPJS patients was 65%. It means that each general patient of the Kajen Public Hospital obtained surplus as many as 21% otherwise each BPJS patient obtained minus as many as 35%. Arrangement of clinical pathway and implementation of final clinical pathway could be used as quality control of the Kajen Public Hospital. The hospital management needs to trace costs, to monitor, and to evaluate the obedience of clinical pathway.

Recent research indicates that during the design of teleinformatic system the tradeoff between the systems performance and the system protection should be made. The traditional approach assumes that the best way is to apply the strongest possible security measures. Unfortunately, the overestimation of security measures can lead to the unreasonable increase of system load. This is especially important in multimedia systems where the performance has critical character. In many cases determination of the required level of protection and adjustment of some security measures to these requirements increase system efficiency. Such an approach is achieved by means of the quality of protection models where the security measures are evaluated according to their influence on the system security. In the paper, we propose a model for QoP evaluation of security mechanisms. Owing to this model, one can quantify the influence of particular security mechanisms on ensuring security attributes. The methodology of our model preparation is described and based on it the case study analysis is presented. We support our method by the tool where the models can be defined and QoP evaluation can be performed. Finally, we have modelled TLS cryptographic protocol and presented the QoP security mechanisms evaluation for the selected versions of this protocol.

With mobile technologies increasingly weaving themselves into the fabric of our communities, it would be beneficial to increase our understanding of how these devices will affect our quality of life. This chapter presents a case study where a set of prototypes of future social technology concepts were generated and used by groups of backpackers in a mobile community. One of these concepts, which facilitated viewing the locations of other group members, is evaluated with regard to how it might affect community development. This and other examples illustrate that communication technologies form a social path which guides individual and emergent behavior of societies. Determination of where these paths lead can be accomplished through the creation of development projects with positive social aims. Using collaborative research methods, considering design outcome spectra, and adding features with implicit cultural values are promising strategies for influencing future communities.

The Impact

Mining activities, in combination with accelerated urbanization growth and climate change, constitutes a major challenge for creating a sustainable development. Thus, the monitoring and assessment of mining effect is mandatory in understanding the impact on the primary physico-chemical characteristics of an environment. In this context, the paper presents the evolution of micro- and macro- nutrients in water, soil and sediment from two industrial areas from Romania (Copșa Mică industrial platform and Baia Sprie mining zone), in order to assess the impact of pollutants on ecosystems. Physico-chemical (pH, NH4+, NO3-, NO2-, TN, TP), base cations (Ca, Mg, Na and K) and micronutrients (Fe, Mn and Zn) have been analyzed in order to evaluate the quality of the environment. For some of the analyzed soils, the concentration of Zn, Mn and Fe exceeded the maximum permissible limits (MPL) imposed by the Romanian legislation, falling within the limit for Alert Thresholds for less sensitive soils. The correlation analysis on water quality parameters revealed that all parameters are more or less correlated with each other Person’s Correlation matrix. Overall, our results demonstrated that the knowledge of the physico-chemical regime of an environment is of great value in the determination of its productivity, usefulness and other characteristics which can facilitate further vegetation restoration and reconstruction and a sustainable development of the ecological environment in a polluted area.

Bacteriological quality of potable water supplying Morogoro municipality and its outskirts (population 135000 people) was assessed by the determination of the most probable number (MPN) of faecal coliforms, Escherichia coli, faecal streptococci andClostridium perfringensfor a period of 6 months. River water and chlorinated pipeborne water were found contaminated with microorganisms in the order of 3·8 x 101to 4·95 x 103; 3·2 x 101to 4·5 x 103; 101to 6·4 x 101and 1·2 x 101to 2·5 x 102/100 ml of water respectively. Injured coliforms in treated water averaged 87 %. Pollution of river water by organic matter was much above acceptable standard. These findings indicate that there is a need for further treatment of water before consumption in order to avoid potential health hazards.

Bond Evaluation

AbstractCement bond logs (CBL) and variable density log (VDL) are one of the vital logging techniques used to evaluate cement-casing-formation bonds before the well testing or execution of the production operation in the well. These logs are also crucial during the workover operation to maintain the integrity of the well. The logging techniques provide a clear view of the quality of cement bonds with casing and formation. The microannulus and other deviations in bonding between the cement and the casing or formation are recorded using this technique. Therefore, this technique is used by the regulatory authorities worldwide for the determination of the cement bond with casing and formation. In this paper, the CBL/VDL logging technique was used to determine the bonding between cement and casing and cement and formation at two different CBM wells from 850 to 1600 m depths in the Raniganj block of Durgapur, West Bengal. Two well, namely, A and B, were analyzed to determine the cement-casing-formation bonds in the study area's coal seam zone. The analysis was carried out at normal and pressure pass to investigate the integrity of the well using the CBL/VDL data. The normal and pressure pass in well A indicated the presence of microannulus in the bonding between cement and casing/formation in the coal seam zone. The corresponding analysis of well B showed poor cement and formation bond at the coal seam zone during the normal pass but good bonding after the pressure pass. Thus, it was observed that the CBL/VDL data were capable of determining the cement-casing-formation bonds in both the well of the study area and the well's integrity.
