Methods: In this study, a survey consisting of structured questions prepared by GlobalWebIndex, which includes user expectations and problems in the use of internet, social media, mobile devices and ecommerce, was used. Results: While the impact of the coronavirus harms people and businesses, it is obvious that just new emerging technologies can be used to solve this problem. It is clear that there is a need for newly developed tools and working methods to overcome such challenges. Restrictions imposed by Governments have led to an increase in the use of digital technologies such as online shopping, digital and contactless payments, remote work, online education, telehealth and entertainment. The ability of societies to support these activities may vary largely due to the availability of \"digitally available\" infrastructure and services. In this way, societies with developed infrastructure are less affected by the effects of the pandemic and can ensure business continuity, and societies with insufficient information system infrastructure experience deep gaps in the continuation of social activities. Conclusion: Obviously, new or improved tools and ways of working are needed to help tackle these challenges. The emerging new technologies have created augmented reality technology by adding layers of digital information such as sound, video and graphics on the appearance of the physical world by affecting the changing living conditions. One of the solutions that can help reduce the social and commercial impact of the pandemic and support business continuity is Augmented Reality (AR), which is defined as a remote assistance area.","PeriodicalId":14256,"journal":{"name":"International Journal of Scientific and Technological Research","volume":"110 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84860369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gains obtained by processing and interpreting data stacks can make significant contributions to institutions and organizations in many managerial issues from production to decision-making processes. It has increased the use of data mining methods in different areas, which support the process of transforming digitalized large-scale data into information. One of the increasingly popular techniques in data mining is clustering, and the K-means algorithm is a non-hierarchical clustering method compatible with large amount of data. This method is widely used in the scientific studies, however the number of clusters and initial centers defined as parameters comes up a disadvantage for the algorithm, especially for those not familiar with the mathematical specificities. Initial centers those generated randomly by K-means usually make the clustering results reaching non-optimal. K-means algorithm is very sensitive in initial centers. More consistent results of K-means clustering can be achieved after computing more than one times. However, it is difficult to decide the computation limit, which can give the optimal result. An improvement of K-means algorithm with this respect will be a contribution on overcoming this disadvantage for scientific studies. In order to solve this problem; NAMGY (Neighborhood and Midpoint Gain Yield) algorithm has been developed, which includes methods that provide optimal selection of parameters according to the properties of objects. This article covers the application of the method of determining the initial centers in NAMGY algorithm. Method: In order to analyze the accuracy of our proposed method, both the standard K-means and NAMGY algorithm were applied on the classified data set those Iris, Yeast and Segment-challenge. And also the performances of the algorithms in terms of the working principle were evaluated on the VitaminB12 data set obtained from the Cukurova University Balcalı Hospital Information Management System. Euclidean distances were calculated between objects and data sets were transformed into values in the range [0, 1] using normalization. Adjusted Rand index was used to evaluate the validity of clusterings. Results: According to the examined results; the applications that reveal the effects of the initial centers on the analysis process of the algorithms have been carried out with different approaches such as the working principle of the algorithm, the effect of the initial centers on the clustering results, the evaluation of the clustering performance. It was again concluded that professional selection of parameters is requirement to increase the usability of a clustering algorithm and the reliability of clustering results. The NAMGY algorithm uses a systematic way to find initial centers which reduces the number of dataset scans and will produce be","PeriodicalId":14256,"journal":{"name":"International Journal of Scientific and Technological Research","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88641125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The perception of time, which is an important element that improves the narrative language of cinema, is related to creating an architectural and spatial image. Cinema and architecture, as two separate disciplines, are not independent from each other in terms of creating a cinematographic place perception. Therefore, the importance of cinema and architecture interaction in creating cinematic place is discussed in this study. The aim of the study is to examine the relationship between architecture and cinema, which are two separate art branches, through the \"perception of place\" and to explain the cinematographic effects of architecture through the example of Wes Anderson's \"The Grand Budapest Hotel\". In both areas, it has been tried to explain to what extent the place's important elements in terms of time, movement, light, color and shadow reflect the reality. While \"design\" is an important issue in fictional places, it is also necessary in terms of creating a space perception. In this study, it is aimed to analyze the film structure with architectural semiotic approach, especially the role of architectural and space usage in cinema, by emphasizing the processes and reference points of the interaction between both disciplines. According to the case of Wes Anderson's The Grand Budapest Hotel (2014), the specific spaces of the film, the perception of space and the role of cinematographic space designs are discussed. In line with this information, subjects such as space design and spatial density in cinema, space, balance, harmony and symmetry in architecture and cinema, construction process and its effects in cinema and the perception of space in cinema were examined. The architectural structure and the suitability of the space design to the story are also discussed in the film. The film, which is considered as an exemplary analysis within the scope of the research, was chosen as a purposeful sampling because it is an example of especially the relationship between harmony and balance in cinema and the relationship between cinema and architecture explore and sets an example.","PeriodicalId":14256,"journal":{"name":"International Journal of Scientific and Technological Research","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81532067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every pandemic outbreak experienced by humans has introduced a new configuration of “what is normal” and has imposed a life with new habits and precautions that became normal. The present pandemic period of COVID-19 has had a negative impact not only on people’s health but also on the economy in many countries where initially the measure of full confinement was adopted only to be followed by controlled deconfinement covering new measures that would enable evolution of the virus to be observed and the national economy to be revived. Many health organizations such as the World Health Organization as well as national governments published various scientific measures and cautioned against risks of nonobservance of these measures. Similarly in Northern Cyprus was undertaken an initial stage of total lock-down followed by a controlled deconfinement aimed at economic revival. The aim of the present article is to establish a guide concerning measures to be adopted in the fight against COVID-19 and to facilitate a most efficient application of such measures. Health measures established by the World Health Organization were reinterpreted with a focus on spaces and turned into a compilation in an effort to establish a guide. Application and interpretation of the guide were demonstrated via three establishments of similar functional and structural characteristics located in proximity of each other in intramural Nicosia.

The experimental animals consisted of 9-week-old Japanese quails, including 105 females and 45 males, and the experiment continued for six weeks. The results showed higher than control group significant effects of the (BPP) supplementation to quail diets on yolk level (P<0.01), shell thickness, and Haugh unit (P<0.05), but not significant effects as raise or decrease were observed on live gain, consumption feed, feed conversion ratio, egg weight, shape index, yolk index, white index, and shell weight (P>0.05).Taken together, these results can be recommended BPP supplementation of quail diets. No significant differences were observed in shape index between different groups at the end of this six-week trial. The shape index values obtained for the Japanese quails in this study were similar to those (79.54%) mentioned in a previous study performed to determine some internal and external quality characteristics of the quail eggs (Özçelik, 2002). During the experimental period it was found that the BBP-supplemented groups showed statistically higher yolk index values (P<0.05), in the first measurement, but no significant differences were observed in the other two measurements. Although the yolk index values obtained in the last measurement were different from the initial measurement results, they were found to be similar to those obtained in a previous study conducted to investigate the effect of selection for live weight on the reproductive performance of Japanese quails (45.01) (Türkmut et al., 1999). The white index values, which are an important egg quality criterion, did not show any significant difference between groups, and it was observed that the BPP-supplemented groups generally showed higher white index values. These values, differed with a study conducted on Japanese quails (11.43) (Özçelik, 2002). While significant differences in the Haugh unit values were obtained between the groups in the first (P<0.01) and second (P<0.05) measurements, no significant difference was observed between the groups in the final measurement (P>0.05). The Haugh unit values ranged between 72.11 and 76.15 on average at the end of the trial, and these values lied between the value (88.930) obtained in study conducted to determine some yield and egg quality characteristics in Japanese quails and the value (68.479) obtained in a study conducted on egg quality and characteristics in Japanese quails (Altınel et al., 1996; Nazlıgül et 2001).
