The purpose of this research is to identify and explain the Rudolf Carnap’s semantical and syntactical theories and its role on the theoretical and practical improvement of ontologies for the effective information retrieval.

Since the present study aims to survey Carnap’s semantics theory and shows the positive and effective points of semantic theory for the effective information retrieval based on ontologies, so the use of philosophical research method is inevitable. Philosophical research can have both "conceptual analysis" and "speculative" methods. The method that used in this research is conceptual analysis and its type is Qualitative methods. The research community includes all books and articles published by Rudolf Carnap in the field of semantics and the properties of ontological tools for the effective information retrieval.

: This study shows that Rudolf Carnap's deductive approaches to the problem of meaning can be used to develop ontologies for retrieval of textual information of resources and Rudolf Carnap's inductive approaches can be used to construct ontological systems in the field of experimental sciences. the rules of Rudolf Carnap's semantic system, such as the rules of classification of signs, the rules of formation of language, the rules of designation, the rules of value, the rules of determination, the rules of truth, The rules of selection and the rules of inference can be used in the structure of ontologies. Also, the rules of selection and the rules of relevance in Rudolf Carnap's semantic system are useful for the development of information retrieval in ontologies. the application of Carnap’s semiotic, syntax and semantics improve the accuracy and comprehensiveness of information retrieval in ontologies.

The application of the Carnap semantic system in the structure of ontologies contributes to the theoretical and practical development of ontologies.

The aim is to provide an appropriate patients informative model of self-care for the medical information system of the country.

This is an applied survey research. Through Cochran's formula sample of 356 individuals were selected from the population of 5,000 individuals. Khajeh Ali (et al., 2020) Qualitative Standard Research Questionnaire (with 2 dimensions, 14 components and 92 questions) was used.

It was revealed that all parameters of the self-care informing factor analysis model of patients in the medical informing system are significant at 95% confidence level and the model has a good fit. Also, care of medical services has a weight of 0.422, the correction component is 0.924 and behavioral care is 0.417. Meanwhile, 0.92 for the component of participation in care, 0.897 for prevention, for the component of personal cares, 0.482, and 0.448 for the component of satisfaction, 0.502 for the component of environmental cares and 0.852 for health have been acquired. Regarding the information dimension, 0.907 for science and knowledge component, 0.852 for processing, 0.887 for news distribution, and 0.798 for knowledge have been acquired. In addition, for the dimensions of information and self-care, weights of 0.69 and 0.77 were obtained, respectively.

Chronic care is the duty of the primary care team with physicians giving extensive part of their time. Since patient care occurs in service delivery units - part of health system and of a larger community – ensuing participatory care. Information behavior research is to help science professionals to be knowledgeable about the information needs of their target community to make the required planning to offer information resources for patient self-care of the country. Obtained model could bring promising result in the medical information system.

The purpose was to investigate the effect of excessive use of social media in the workplace on employees' job performance.

This study is an applied research. Population includes all government employees  through Nov.  2020 to April 2021. A 19-item questionnaire was used to collect and assess the current situation.  Validity and reliability was confirmed. Structural equations have been used to investigate the relationships between the components of the model. LISREL software was used to examine the hypotheses.

Findings have shown that excessive social use (rendering t-statistic of 4.24) and excessive cognitive use of social media in the workplace (according to t-statistic of 2.92 ) have a positive relationship with media fatigue, but hedonistic use has no effect on social media fatigue. Social media fatigue also has a positive relationship with employees' job performance (Based on t-statistic of 7.13). Also, according to z statistic (2.70) social media fatigue plays a mediating role in the relationship between excessive cognitive use of social media in the workplace and employees' job performance. Further, social media fatigue has a mediating role (giving z statistic of 3.64) in the relationship between excessive social use of social media in the workplace and employees' job performance. But social media fatigue does not mediate the effect of hedonistic use on employees' job performance.

Conferring unnecessary use of social media includes three dimensions. The role of these dimensions in influencing fatigue and job performance was examined and it was found that each of these dimensions has a different effect on fatigue and job performance. Therefore, this issue helps to theoretically understand the relationship between excessive use of social media and job performance, as well as for managers to formulate policies related to the use of social media.

The study aims to explain the role of brand equity in increasing market share, based on information seeking behavior and needs in Kish commercial centers.

This is applied exploratory-explanatory qualitative research. Population included branding and economics experts who were selected as a research sample by targeted snowball method of 14 people. To analyze the information related to the semi-structured interview, the content analysis method based on open coding, axial coding and selective coding based on the data theory of the foundation was used.

The results showed that marketing strategies through 5 elements of product, price, location, promotion, process management. Management factors through two components of leadership and human resource management have added value to the brand of Kish commercial centers. The added value created creates a competitive advantage. Also, environmental capabilities include: Infrastructure, technology, environmental features, security and recreation as background conditions and external factors including political-economic factors, information seeking behavior and information needs through customer information and market information as an intervener. The competitive advantage of Kish commercial centers is affected and ultimately increases the market share or in other words the development of customers and improves the financial performance of these centers.

The results showed that increasing market share is a complex process and is strongly influenced by brand value added, which is affected by marketing strategies and management factors. In addition, in order for Kish commercial centers to be known as a brand, they must first gather the necessary and sufficient information about customers and then the market.

The purpose was to determine the attitude of Illam’s public librarians regarding online privacy.

This is an applied survey research.  Out of the population of public Librerians in Illam,  136 public librarians were selected as a sample. Toman and McKinnon (2018) questionnaire was the intruemnt used to collect data. The questionnaire reliability of 0.91   was obtained through Cronbach's alpha. In order to analyze the data, frequency distribution tables and chi-square test were used by SPSS.

Librarians are concerned that government and corporations collect a great deal of personal information about them, and believe that government agencies and institutions should not share individuals' personal information with third parties except with the individual's consent.

There is an increased concerns about privacy in the libraries, which has amplified over the last five years. Public libraries do not teach online privacy expertise to users and librarians. Also, some librarians believe that libraries have no policy on protecting users' privacy. Public libraries in Ilam province should take additional stern measures to protect the online privacy of librarians and users and formulate policies in this area, as well as explain the existing policies to the librarians.

The purpose is to identify the components of health literacy amongst University library users.

This purpose-based research is a qualitative-quantitative survey study. The qualitative part concentrates on the individuals with background in health literacy and research. In the quantitative part students at the libraries of the University of Tehran were surveyed. The research instrument was a structural questionnaire on health literacy of individuals in the community. Reliability of  more than 0.7 was obtained via Cronbach’s alpha

It is important to mention that understanding health information stood at the desirable level and other components stood at a comparatively appropriate stage among the elements of health literacy of users at the University Library of Tehran. Although there is a significant relationship between health literacy skills with income, there is no significant relationship among gender, age, faculty, and level of education with health literacy skills.

It is necessary to measure health literacy practically and apply the results in the community and other comparable communities. The level of health literacy could increase considerably by using programs to promote the health literacy of the community.
