With the COVID-19 pandemic, many hospitals have collected Electronic Health Records (EHRs) from patients and shared them publicly. EHRs include heterogeneous attribute types, such as image exams, numerical, textual, and categorical information. Simply posing similarity queries over EHRs can underestimate the semantics and potential information of particular attributes and thus would be best supported by exploratory data analysis methods. Thus, we propose the Sketch method for comparing EHRs by similarity to provide a tool for a correlation-based exploratory analysis over different attributes. Sketch computes the overall data correlation considering the distance space of every attribute. Further, it employs both ANOVA and association rules with lift correlations to study the relationship between variables, allowing a deep data analysis. As a case study, we employed two open databases of COVID-19 cases, showing that specialists can benefit from the inference modules of Sketch to analyze EHRs. Sketch found strong correlations among tuples and attributes, with statistically significant results. The exploratory analysis has shown to complement the similarity search task, identifying and evaluating patterns discovered from heterogeneous attributes.

This study aimed to determine the reality of education and religious insight of madrasah teachers as well as the relationship between education and religious insights with madrasah teachers’ work motivation in Serang District, Banten Province. The method used is descriptive method with case study approach and quantitative data analysis. The research sites were at Sultan Agung Madrasah Tirtayasa, Nurul Huda Madrasah Baros and Raudhatul Ulum Madrasah Anyer. The respondents were 50 councilors in each madrasah. Data collection techniques used in the study were questionnaires, observations, and interviews. Based on the data analysis using statistical approaches and the development of a linear regression formula and multiple regression, correlation values are quite high among the variables of educational insights (X1) with the variables of madrasah teachers’ work motivation (Y); and between variables of religious insight (X2) with the madrasah teachers’ work motivation (Y); as well as between the variables of religious and education insight (X1 and X2) with the variables of madrasah teachers’ work motivation (Y).

This study investigated the relationship between financial development and economic growth in Hungary using a case study approach. Majority of previous studies on the same or similar topic have so far used regression and or econometric methodologies to examine the nature of the relationship between financial development and economic growth. Not a single study the author is aware of used a case study approach to discuss the relationship between the two variables. It is against this background that the author decided to use the case study approach that allows the author to really deepen an understanding of the relationship between the two variables in Hungary. Apart from being narrowly focused on regression or econometric approaches, previous studies on the same or similar topic in Hungary excluded a broad range of financial development variables. The current study departs from these previous studies as it used a case study approach and taken into account a broad range of financial development variables. From the trend analysis done in section 3, it appears that the relationship between financial development and growth in Hungary during the period under study is not clear. A definite and clear cut conclusion could not be reached about the relationship between the two variables in Hungary hence the use of econometric data analysis approaches in conjuction with the case study approach is recommended.

The purpose of this study is to examine the relationship between the diagnosis and the cost of patient care for those with diabetes in Medicare. In this analysis, the author used data sets about outpatient claim, inpatient claim as well as beneficiary demography information for the year 2004, all of which were taken from the Chronic Condition Data Warehouse provided by the Centers for Medicare and Medicaid. The author analyzed the cases for diabetic inpatients and outpatients by different methods. For outpatient analysis, exploratory data analysis and linear models were used .The results show that the total charges for diagnoses are reduced considerably for payment. The distribution of the total charges follows a Gamma distribution. The output of the generalized linear model demonstrates that only 15 out of the top 20 primary treatments for charges are statistically significant to the expenditures on outpatients.

The purpose of the study is to identify the relationship between public perceptions about audit opinion, audit findings and the level of corruption in Papua Province (Case Study of the Government of Keerom Regency, Jayapura Regency and Sarmi Regency). A sample of 120 respondents consisted of 40 respondents from each district. Data collection techniques through questionnaires and data analysis using the Partial Least Square (PLS) approach. The results showed the greater the perception of audit opinions the greater the trust in corruption handled by the auditor. Meanwhile, the results of the study showed that the magnitude of audit findings carried out by BPK influenced the level of corruption that occurred. Audit findings can detect corruption in the government and local government efforts to make improvements according to the auditor's recommendations can significantly reduce the level of corruption.

Purpose of the study: This research aimed at investigating the extent of anxiety experienced by TOEFL test-takers in the Indonesian context as EFL learners. Methodology: The participants of this study were 50 university students from various non-English majors. They were selected by using purposive sampling. The research design was descriptive quantitative method, in which a 10-question questionnaire was used as the research instrument. The questions were scored by using a five-point scale and the data were analyzed by using the three steps of data analysis. Main Findings: The result of the data analysis showed that more than 80%percent of students experienced moderate anxiety before and during the TOEFL test-taking while the rest (20%) suffered from mild anxiety. Applications of this study: The research findings can benefit TOEFL Preparation classes’ instructors, by which they can take the anxiety variable into account when teaching TOEFL so that the level of students’ anxiety before and during the test can be minimized. Novelty/Originality of this study: Relatively little research examined EFL students’ anxiety in the TOEFL test. Others are much devoted to the anxiety aspects within English classroom contexts such as in anxiety in reading, writing, and speaking skills, the relationship between anxiety and motivation, as well as intelligence dominance among non-low proficiency students. Therefore, this research is devoted to a high-stake test (TOEFL test), which has not been studied previously by any researchers.
