“…The correlation matrix in table 1 clearly demonstrated insignificant to low correlation (the remaining were omitted because of very low values). An exception moderate negative correlation existed between both hardness and dissolution of Pseudoephedrine Hydrochloride (Witz et al, 1990). This brought the focus into hardness first for analysis using SPC.…”

Drugs manufactured in pharmaceutical companies -that do not comply to current Good Manufacturing Practice (cGMP) -are considered by Food and Drug Administration (FDA) as "adulterated medicines", even if they did not impose any health or quality risk to the final consumers. Non compliance to cGMP has adverse effects on both customers and companies with think again escalating legal penalties may be issued. In the current study, newly established pharmaceutical plant launched film coated tablet for treatment of common cold symptoms. The local regulatory agency in collaboration with quality team of a well-established pharmaceutical company in the area has conducted large survey that covered new firms to elucidate the compliance of the facilities of those newly emerging companies to cGMP, partially using statistical process control (SPC). The generated results for the product by quality control (QC) and in-process control (IPC) were processed using statistical software packages. Trending of data brought the focus on hardness test which later highlight the need to investigate dissolution pattern of the three active components of the dosage form. Time series plot of hardness for 195 batches manufactured during 2016 showed non consistency and stability of the process which can be segmented chronologically into three distinct segments. A significant negative correlation (-0.64 by Spearman correlation) was found between the hardness and the dissolution of one the active pharmaceutical ingredient (API) viz, Pseudoephedrine Hydrochloride. Inconsistent operation during hardness as IPC test was reflected in the dissolution QC test. Effect on other properties should be investigated.

“…The introductory analysis of the relationships between perceived odors and socio-demographic characteristics of inhabitants was based on rank-order Spearman correlation coefficients. The strength of correlation was interpreted according to the following scheme [59]: |r| ≥ 0.9-very strong correlation, 0.7 ≤ |r| < 0.9-strong correlation, 0.5 ≤ |r| < 0.7-medium strong correlation, 0.3 ≤ |r| < 0.5-weak correlation, |r| < 0.3-very weak correlation (negligible). An analysis of correspondence was performed in order to obtain a bi-plot presenting the correlation among variables.…”

Impact of Odor Nuisance on Preferred Place of Residence

et al. 2020

Context of the research:Research is increasingly carried out to take into account the social behavior of residents, the type of industry located in the area, and perceived preference for the place of residence. The quality of life in urban space is increasingly seen as a problem of cooperation between various stakeholders. These studies not only identify factors and sources of odor emissions, but also serve as the basis for creating systems to alert people living in areas adjacent to industrial areas or harmful and unpleasant industrial emissions. In recent years, environmental issues, particularly unpleasant sensory experiences, have been one of the most important acceptance criteria. Aim of the article: The aim of the study is to assess the impact of odor nuisance in the south-eastern part of Kraków (Płaszów) on the residents' decision to leave their place of residence. In particular, the research goal was achieved to indicate which of the unpleasant odors may cause a change of residence, as well as to assess the degree of their impact on the decision to move, taking into account the social and demographic characteristics of residents. New in the article: The novelty of the work was the finding out of the residents' opinions about the quality of life by accepting the place of residence, taking into account the aspect of odor nuisance. Previous studies on odor nuisance have focused on the emission of odors from individual plants. A novelty of this research is its implementation in an urban area, in which numerous industrial plants are located, with various odors emitted. Research methodology: To assess odor nuisance, a measuring tool developed in accordance with VDI 3883 guidelines was used, based on the latest research results on odor and noise nuisance. The questionnaire was developed based on German experience. Conclusions from the research: The data obtained as a result of the research allow us to state that specific smells are so burdensome that they may cause the necessity to leave the place of residence, because the respondents feel various unpleasant smells that have an adverse impact upon the quality of life that they perceive. A possible need for relocation of domiciles out of the current place of residence due to unpleasant smells would affect the perceptible, specific level of grief-the greater it is, the more attached the residents are to their current place of residence.

“…The percentage of agreement was calculated by the fraction of the number of ratings in agreement with the total number of ratings (i.e., agreements + disagreements). A percentage of agreement above 90% is required to consider as a "high agreement" [13].…”

Inter-Rater Reliability, Concurrent Validity and Sensitivity of Current Methods to Assess Trunk Function in Boccia Players with Cerebral Palsy

et al. 2020

Trunk function is a core factor to allocate Boccia players with cerebral palsy in BC1 and BC2 sport classes, according to the Boccia International Sports Federation (BISFed). However, the appropriateness of the current test to assess trunk function has never been studied to determine its reliability, validity and sensitivity to discriminate between different levels of impairment. Thirty-six players (BC1 = 13 and BC2 = 23) took part in this study. Trunk control was assessed through the BISFed trunk function scale (TFS) and a posturographic test battery consisting of two static and three dynamic tasks. The inter-rater reliability for the BISFed TFS was set at 94.44% of agreement. Moderate-to-high correlations were obtained between posturographic tasks (0.39 < r < 0.96; p < 0.05–0.01), while the BISFed TFS only correlated with two of the dynamic tasks and the overall dynamic score (−0.38 < r < −0.51; p < 0.05). The BISFed TFS was not able to discriminate between sport classes, whereas the static posturographic task did so (p = 0.004). Even though the current BISFed TFS presented good inter-rater reliability, it does not seem to have enough sensitivity to discriminate between BC1 and BC2. Although the static posturographic tasks were able to discriminate between sports classes, it seems necessary to develop new field tests assessing participants’ trunk stabilization abilities.
