Internet users are increasingly invited to express their opinions on various subjects in social networks, e-commerce sites, news sites, forums, etc. Much of this information, which describes feelings, becomes the subject of study in several areas of research such as: "Sensing opinions and analyzing feelings". It is the process of identifying the polarity of the feelings held in the opinions found in the interactions of Internet users on the web and classifying them as positive, negative, or neutral. In this article, we suggest the implementation of a sentiment analysis tool that has the role of detecting the polarity of opinions from people about COVID-19 extracted from social media (tweeter) in the Arabic language and to know the impact of the pre-processing phase on the opinions classification. The results show gaps in this area of research, first of all, the lack of resources when collecting data. Second, Arabic language is more complexes in pre-processing step, especially the dialects in the pre-treatment phase. But ultimately the results obtained are promising.

The purpose of the research was to explore the factors which affect service innovation in organizations and how the utilization of resources can improve organizational performance, and gain a competitive advantage by adopting numerous innovative practices. This study hypothesizes Service Innovation Readiness (SIR) to consist of Strategic Alignment favoring Service Innovation (SASI) and Empowering Structure for Service Innovation (ESSI), which regulate the organization's preparedness to adopt service innovation changes. Six dimensions were identified and analyzed to understand their effects on SASI and ESSI. A structured questionnaire on a 5-point Likert scale was used to collect data from the selected hospitals of Saudi Arabia. The research results contribute considerably to the subject matter by theorizing SIR and the complex variable settings essential for embracing SI. This research also provides some understanding of the service innovation management dimension through a complete assessment that measures the organization's readiness and attempts to direct organizations' efforts to achieve and sustain competitive advantage. The study conducted is unique in the current geographic limits and has explored numerous SI areas of an organization's readiness to adopt service innovation.

The purpose of this study is to find out whether Achievement Tests are fully performing their role as an objective standard that measures student's educational achievement level by analysing the content validity of Achievement Tests developed by KICE and teachers at elementary school. In the study, the content validity of achievement tests were analyzed in the behavioral content objective dimensions. 60 instructional objectives from the Unit one to the Unit six contained in the teachers' guidebook for the elementary third-grade Math subject were analyzed into dimensions of behavior and content. And the Achievement Test developed by KICE and teachers in five elementary schools randomly chosen were collected and analyzed. Then, differences of the proportion between instructional objectives and evaluative objectives in each dimension statistically were verified. The results of the study are as follows : 1. In the dimension of behavior, as analysing and comparing the content validity of achievement tests, there was no significant difference in all domains(knowledge, comprehension, application, analysis, synthesis and evaluation). (p<.05) Therefore, it could be concluded that content validity of the Achievement Test is very high. 2. In the dimension of content, similarly there is no significant difference in all domains between achievement tests by both KICE and teachers. (p<.05) Therefore, the content validity of all tests are very high. In conclusion, it could be concluded that content validity of achievement tests is considerably high in content and behavior dimension. The study suggest the followings : 1. By expanding to the other subjects, there are needs to analyze and verify the content validity of achievement tests. 2. Even the content validity of achievement tests is considerably high however, achievement items are focused on evaluation 3 domains(knowledge, comprehension, application). Therefore evaluation evenly among 6 cognitive domains is required. And further to reduce the deviation of schools, there are needs to active interchange between teachers.

Instructional materials including problem situations or problems or tasks on real-life situations are considered as an important and significant factor to lead a successful math instruction. MiC Textbook is a representative one showing good examples and tasks including fluent realistic situations on the basis of the background of the Freudenthal's theory. This study explores concretely and in detail the type of level of mathematical tasks, by the subject of MiC Textbook. To accomplish this, this study reconstructs and establishes an elaborated analysis framework using 'the cognitive demand level' suggested by Stein, et, al. The cognitive demand level is comprized of four elements such as Memorization Tasks, Procedures Without Connections Tasks, Procedures With Connections Tasks, and Doing Mathematics Tasks. Memorization Tasks and Procedures Without Connections Tasks are considered as low level tasks, and Procedures With Connections Tasks and Doing Mathematics Tasks are as high level tasks. MiC Textbook is comprized of the four areas of 'number', 'algebra', 'geometry and measurement', and 'data analysis and statistics'. This study deals with the tasks relevant to Function content dealt with in MiC 3 level Textbook, and explore the level of cognitive demands on each task.

This study questions that mathematical evaluations strive to memorize fragmentary knowledge and have an objective test. To solve these problems on mathematical education We did descriptive test. Through the descriptive test, students think and express their ideas freely using mathematical terms. We want to know if that procedure is correct or not, and, if they understand what was being presented. We studied this because We want to analyze where and what kinds of faults they committed, and be able to correct an error so as to establish a correct mathematical concept. The result from this study can be summarized as the following; First, the mistakes students make when solving the descriptive tests can be divided into six things: error of question understanding, error of concept principle, error of data using, error of solving procedure, error of recording procedure, and solving procedure omissions. Second, students had difficulty with the part of the descriptive test that used logical thinking defined by mathematical terms. Third, errors pattern varied as did students' ability level. For high level students, there were a lot of cases of the solving procedure being correct, but simple calculations were not correct. There were also some mistakes due to some students' lack of concept understanding. For middle level students, they couldn't understand questions well, and they analyzed questions arbitrarily. They also have a tendency to solve questions using a wrong strategy with data that only they can understand. Low level students generally had difficulty understanding questions. Even when they understood questions, they couldn't derive the answers because they have a shortage of related knowledge as well as low enthusiasm on the subject.

Statistics education research is an important basis for improving the practice of statistical education by describing, predicting, and explaining the phenomena of statistical education. In this study, the research trends in Korea were analyzed through the statistical education research papers published in major Korean mathematics education journals on the 21st century. 99 papers published in these journals from 2000 to 2016 were categorized by journals, research subjects, research methods, and, topics. As a result, it was shown that there are not many statistics education researchers, so domestic researches are dependent on some researchers. In addition, the numbers of studies of human subjects and human non-subject researches were similar. There were few studies of university students, and the studies of teachers' subjects was gradually increasing since 2010. In the case of research methods, the numbers of experimental and non-experimental studies seem to be similar, but this is a result of the increase in qualitative research and mixed research since 2010. Last, many studies about domestic statistics education are on teaching and learning, and the studies on reasoning and understanding have been increasing. In this study, we see the research trends of domestic statistics education and provide implications for the future researches and development directions of statistical education research.

The main purpose of the present study is to survey the major iudexing bulletins of national nature in Korea, to define such problem areas as lacunae, duplicates and limitation in coverage in the indexing services currently available in Korea, and to make some suggestions for action for improving the existing indexing services in the light of general principles and the tradition and constraints unique to Korea. The major findings and conclusions reached at this study are summarised as follows: (A) A new indexing bulletin of general nature covering the entire field needs to be created in each of the following fields without an established indexing service available for the outcome of research and development activities in Korea. (1) Philosophy (2) Religion (3) Pure sciences (4) Art (5) Language (6) Literature (7) History (B) A new specialised indexing bulletin needs to be created in each of the following fields where indexing services are heavily utilised but no, or only partial, indexing service is available. (1) Social sciences (a) Statistics (b) Sociology (c) Folklore (d) Military science (2) Pure sciences (a) Mathematics (b) Physics (c) Chemistry (d) Astronomy (e) Geology (f) Mineralogy (g) Life sciences (h) Botany (i) Zoology (3) Applied sciences (a) Medicine (b) Agriculture (c) Civil engineering (d) Architectural engineering (e) Mechanical engineering (f) Electrical engineering (g) Chemical engineering (h) Domestic science (C) Publication of the indexing bulletins suggested in A and B above may be ideally carried on by a qualified and dependable learned society established in the respective fields and designated by the Minister of Education, and should be financially supported from the public fund under the provisions of Art. 27 of the Scientific Research Promotion Act of 1979. (D) The coverage and contents of the four indexing bulletins in the field of banking and financing published by the Library of the Bank of Korea are similar and considerably duplicated. It is, therefore, suggested that the four indexing bulletins are combined in one to form a more comprehensive and efficient bibliographical tool in the field and it is further developed into a general guide to the literature produced in the entire field of economics in Korea by gradually expanding its subject coverage. (E) For the similar reasons stated in D, the Index to the Articles on North Korea and the Catalogue of Theses on North Korea, both publisheds by the Ministry of Unification Library, are suggested to make into one. The Index to the Articles of the Selected North Korean Journals and the Index to the Articles of the North Korean Journals in Microfilm Housed in the Ministry of Unification Library, both published by the same Library, are also suggested to be combined in one. (F) The contents of the Catalogue of the Reports Submitted by Government Officials Who Have Travelled Abroad, published by the National Archives are included in the Index to the Information Materials Related to Government Administration, published by the National Archives. The publication of the former is hardly justified. (G) The contents of the Index to Legal Literature published by the Seoul National University Libraries and those of the Law Section of the Index to Scholastic Works published by the National Central Library are nearly identical. One of the two indexes should cease to be published. (H) Though five indexes are being published in the field of political science and four in the field of public administration, their subject coverage is limited. Naturally, these indexes are little usable to many other researchers in the two fields. A comprehensive index covering all the specialised areas in each field needs to be developed on one or all the existing indexes. (I) It is suggested that the Catalogue of the Scholastic Works on Curricula published by the National Central Library expands its subject coverage to become a more usable and effective index to all the researchers in the field of education. (J) The bimonthly Index to Periodical Articles and the specialised index by subject series published by the National Assembly Library, and the Index to Scholastic Works published by the National Central Library are expected to increase their coverage and frequency of publication to be used more effectively and more efficiently by all users in all fields till the indexing bulletins suggested in this study will fully be available in Korea.
