Benchmarking is more than just a comparison of measures about different company's performance in a wider sense. It is a methodology of learning-comparing-learning, at least within small and medium sized enterprises. This learning is not just limited to learn by copying successful concepts from other enterprises or competitors. It starts in learning more about the own company, about its structure and processes causing its own success or its failure. This kind of learning is necessary before the enterprise starts watching for a suitable Benchmarking partner. Learning from each other's strengths and weaknesses is the main goal of the European research project Quality beyond Borders! By using the Benchmarking methodology, small and medium sized enterprises get the opportunity to take part in a Benchmarking study and can learn more about the different strengths and weaknesses of other enterprises on both sides of the border. The results of such a Benchmarking can help to identify potentials for future cooperations among German and Polish enterprises in the same market or business. These potentials can lie in different ways of realising the same success or top-position. The Benchmarking study is not focused on an special business or region. That helps to find out trends for different kinds of top-positions, which can be claimed in all markets within a country. Every trend is characterised by different success factors which are responsible for the success in this top-position. In a first overview, the results of the Benchmarking study show 5 different groups of top-positions within a market which all have different profiles regarding to the importance of their success factors. By the end of the Benchmarking study it will be possible, to give answer about the special reasons for different kind of successes of these groups. These answers can be related to a special region within a country, a special business or of course related to possible differences in the expression of the group success factors in comparison of both countries.

This study analyzed the variability and correlation between ground-level air pollutant concentrations and the atmospheric mixing layer height using data from four types of air pollutants (PM_2.5, PM₁₀, NO₂, and O₃) collected at AirKorea monitoring stations nationwide over a five-year period (2018~2022), and aerosol backscatter data observed by the Vaisala CL31 to derive atmospheric mixing layer heights. The five-year trends and variability of ground-level air pollutant concentrations under seasonal and hourly conditions were examined, as well as the seasonal distribution and diurnal variation of the atmospheric mixing layer height. Five correlation coefficient methodologies were applied to analyze the correlations between ground-level air pollutants and atmospheric mixing layer height under various seasonal and hourly conditions, confirming the dilution effect of the atmospheric mixing layer height. The results showed that PM_2.5, PM₁₀, and NO₂ generally had negative correlations with the atmospheric mixing layer height, while O₃ showed a strong positive correlation up to an altitude of 1,200~1,500 meters, and a negative correlation beyond that altitude. It was also shown that a single high concentration event (e.g., PM₁₀) can alter the overall correlation. The correlation can also vary depending on the characteristics of the correlation coefficient methodology, highlighting the importance of applying the appropriate methodology for each case during the analysis process.

Purpose: Based on the author's adapted invariant choice, this study is to present the methodology and the calculation of the integral index of the digital component of the quality of life. By analyzing the digital indexes, the study is also to discuss distribution of ICT and the digital quality of life of the population of Kazakhstan and its regions. Research design, data, methodology: In this research, the method of calculation of integral assessment of the indicator was used, which indicates index constructs. The study analyzed objective secondary data for the period 2017-2019, which was the database from official websites of the Committee on Statistics of the Republic of Kazakhstan. Results: The study produced an integral code for assessing digital components of living standards of the population, consisting of five groups sub-indexes. Conclusions: Based on the provided analyses, we can confirm the existence of a significant difference of all the indicators of digital living standards of the population between the two leading cities: Almaty city and Nur-Sultan city. Furthermore we can deduce the differences of the examined indexes for other regions of Kazakhstan. Despite the rapid adoption of digital technologies, Kazakhstan still has significant digital gaps among cities indicating regional differences in the speed of implementation and distribution of digital technologies.

In a study, the selection of a relevant methodology cannot be determined without an effort First of all, the philosophical view or understanding of the nature of a study area will be agreed, based on which a series of judgment will be performed on a process identifying a foundation or a validity of a knowledge. The findings are as follows. First, it analyzed the trend of food serviceㆍculinary art-related studies by subject and examined its awareness. The most studies are related to trend analysisㆍfood service, 104 papers, following by financial and strategic fulfillment, 76 papers. Service quality and customer-related studies are 38, individual and organization-related studies are 31 papers, education training 18 papers, while legal review are only 2 papers. Second, for trend analysis and awareness on study methodology, research study is at the first, 39%, following by literature study, 38.7%. Most studies are performed research and literature studies together.

The methodology of six sigma originated at Motorola in the early 1980s is now days proved to be an effective way in improving the quality. Many companies are paying their attentions to 6 sigma quality technique, proved to be successful by many examples of advanced firms. However most companies where Six sigma is implemented confront many difficulties in service industry. In paper we research successful Six Sigma in the service industry.

The research proposes the complementary methodology using integrated hypothesis testing and confidence interval models that can be identified the statistical difference and practical equivalence. The models developed in this study can be used in the quality improvement processes such as QC story 15 steps. For the expressions of CI4LSD(Confidence Interval for Least Significant Difference) and CI4TOST(Confidence Interval for Two One-Sided Tests) are simple, quality practioners can efficiently handle them. CI4TOST models as a complement can be applied when CI4LSD models are influenced by sample size and precision.

This research was studied to optimize the recipe of rice pound cake with two concentrations of Euonymus alatus and grape seed oil, using central composite design (CCD). The mixing condition of rice pound cake was optimized by subjecting it to sensory evaluation and mechanical and physicochemical analysis, using response surface methodology (RSM). The results of the mechanical and physicochemical analysis showed significant values for color (lightness, redness, yellowness), texture (hardness, springiness, chewiness, gumminess, cohesiveness), loss rate, volume, specific volume, sweetness, saltiness, moisture content and pH (p<0.05). The results of the sensory evaluation showed significant values for color, flavor, taste, softness, appearance and overall quality (p<0.05). As a result, the optimized compounding ratio was found to be 4.28 g of Euonymus alatus and 33.18 g of grape seed oil.

Robust design (RD) has emerged as a key feature in process design and development for more than twenty years. Many researchers and industrial engineers around the world have invested their intensive efforts to develop and apply RD in many fields in order to improve quality of output products. However, there is also room for improvement. The primary objective of this research is to determine "robust formulation" of a medicine by checking its gelation index. In order to achieve this target, based on the nature of problem, at first, a customized experimental format is designed for obtaining data. Second, time-depended responses based models are developed by the proposed inverse problem (IP) methodology. Third, an RD model based on mean square error (MSE) concept is introduced for time-depended responses. Finally, the proposed approach is illustrated by a case study while comparing obtained results to the response surface methodology (RSM) approach.
