Published: February 2021

Motivation/Background : Consumer satisfaction is very important for a tourist spot, because it determines the ability and level of profit it can achieve. Because it is necessary to pay attention to things that have the potential to affect consumer satisfaction, including the Marketing Mix. This study discusses the aspects of the marketing mix that affect consumer satisfaction at tourist attractions in the city of Tomohon. The aim is to determine the effect of the Marketing Mix on Customer Satisfaction. Marketing Mix (Marketing Mix) is a set of marketing tools that companies use to achieve goals in target markets. Marketing Mix includes variable Product (Product), Price (Price), Place (Place) and Promotion (Promotion). Consumer satisfaction is the feeling of pleasure or disappointment of a customer that arises after comparing perceptions of the performance of a product and its expectations.
Method: In this study, the data collection techniques used were observation, interviews and a list of questions given to consumers or guests on the object under study. The variables measured are the factors of the marketing mix including product (X1), price (X2), place (X3) and promotion (X4), and customer satisfaction (Y). The analytical method used is Multiple Linear Regression Analysis.
Results: From the analysis results obtained the value of the coefficient of determination (r 2 ) of 0.889; which shows that the factors of the Marketing Mix have a contribution or proportion of the contribution to the variation (fluctuation) of Consumer Satisfaction by 88.9%, while the remaining 11.1% is explained by other factors.
Conclusions: From the research results, the value of the Correlation Coefficient (r) is 0.943 (94.3%) or close to 1 (100%), which indicates that there is a very close and positive relationship between the Marketing Mix and the Consumer Satisfaction.

The aim of this study was to characterize the hippocampus in Sudanese epileptic patients in MR images using image texture analysis techniques in order to differentiate hippocampus between the normal and epileptic patient. There were two groups of the patients were examined by using Signal-GE 1.5Tesla MR Scanner which was used with patients with known epilepsy and normal T1 weighted brain. MRI finding patients, 101 and 105 patients respectively examined in period from December 2017- March 2018, where the variables of the study were MRI images entered to the IDL program as input for further analysis, using window 3*3 the images texture was extracted from hippocampus (head, body and tail) that include, mean, STD, variance, energy, and entropy then the comparison was made to differentiate between the normal and abnormal hippocampus. The extracted feature classified using linear discriminate analysis. The classification score function is used to classify the hippocampus classes was as flows:
Epileptic= (.271×mean) + (.026×variance) + (7.475× Part) -32.134
Normal= (.240×mean) + (.052×variance) + (2.960× Part) -13.684
The study confirmed that it’s possible to differentiate between normal and epileptic hippocampus body, head, and tail in sagittal section texturally. The result showed that the classification result is best in the tail where higher classification accuracy will be achieved followed by body and then head.

Published: February 2021

O objetivo deste artigo é analisar os desafios do uso do QR Code encontrados por professores no ensino remoto. Considerando que a pandemia de Covid-19 trouxe diversos infortúnios à sociedade, em especial aos sistemas de ensino, cujas aulas presenciais estão paralisadas desde março, as tecnologias digitais, muitas vezes ignoradas, passaram a ser fundamentais para manter o vínculo com o estudante. Os dados examinados nesta investigação, sob a óptica da Teoria Fundamentada, foram produzidos em um curso de formação continuada, no formato EaD, oferecido aos professores da rede pública do Brasil durante os meses de abril e maio de 2020. Esse curso teve como objetivo apresentar os recursos e aplicações do QR Code, um código de resposta rápida, capaz de armazenar um grande volume de informações. Os resultados indicaram que a comunicação entre professores e alunos foi um grande desafio, pois muitos estudantes não tinham acesso à internet naquele momento, inviabilizando o recebimento das propostas planejadas pelos professores com o uso do QR Code. Entretanto, alguns professores adaptaram as propostas e as desenvolveram com públicos distintos, conseguindo, assim, vivenciar as possibilidades pedagógicas do QR Code. Por fim, é necessário e urgente que o ensino seja reavaliado, notadamente o ensino presencial, de modo que as tecnologias digitais sejam um meio significativo em prol da aprendizagem, para além dos tempos de pandemia.

OBJECTIVEThe diagnosis of glioma remains disheartening in the clinical realm. While a multitude of studies and trials have shown promise, improvements in overall survival have been disappointing. Modeling these tumors in the laboratory setting has become increasingly challenging, given their complex in situ behavior and interactions for therapeutic evasion. Dogs, particularly brachycephalic breeds, are known to spontaneously develop gliomas that resemble human gliomas both clinically and pathophysiologically, making canines with sporadic tumors promising candidates for study. Typically, survival among these dogs is approximately 2 months with palliation alone.METHODSThe authors have completed the first stage of a unique phase I dose-escalating canine clinical trial in which the safety and tolerability of M032, a nonneurovirulent oncolytic herpes simplex virus–1 vector genetically engineered to express interleukin-12, are being studied in pet dogs with gliomas undergoing maximum safe tumor resection and inoculation of the cavity with the viral infusate.RESULTSTwenty-five canine patients were enrolled between January 2018 and August 2020. One patient was electively withdrawn from the trial by its owner, and 3 did not receive the virus. For the 21 dogs that remained, 13 had high-grade gliomas, 5 had low-grade gliomas, and 3 were undetermined. According to histopathological analysis, 62% of the tumors were oligodendrogliomas. At the time of this report, the median overall survival from the date of treatment was 151 days (± 78 days). No significant adverse events attributable to M032 or dose-limiting toxicities have been observed to date.CONCLUSIONSIn this largest study of oncolytic viral therapy for canine brain tumors to date, treatment with M032 did not cause harm and the combination of surgery and oncolytic viral therapy may have contributed to prolonged survival in pet dogs with spontaneous gliomas. Forthcoming in-depth radiographic, immunohistochemical, and genetic analyses will afford a more advanced understanding of how this treatment impacts these tumors and the immune system. Our goal is to utilize these findings bitranslationally to inform human studies and refine therapies that will improve outcomes in both humans and pet dogs with gliomas.
