This study aims to determine the effects of wall covering materials (wood, concrete and metal) used indoors on participants’ perceptual evaluations. The differences among participants’ perceptual evaluations regarding indoor physical environmental factors by occupation and gender were examined.

Cafes were selected as research environments. Virtual experimental spaces using three different wall covering materials were modelled and participants’ assessment of the physical environmental factors of these virtual spaces was measured through a detailed questionnaire.

Cafes using light-coloured wall covering materials were perceived more favourably than cafes using dark-coloured wall covering materials, and cafes with light-coloured wooden wall coverings were considered as a warmer material than cafes using concrete and metal. Participants who received design education (architect, interior architect) perceived physical environmental factors of cafes more negatively than those who did not receive design education (lawyer, economist, accountant, etc.). Male participants evaluated the physical environmental factors of cafes more positively than female participants for all adjective pairs. Except for two adjective pairs, no significant difference was found among the evaluations according to genders for the other adjective pairs.

This study revealed new results about customers’ choices of wall covering materials and offered designers new alternatives for materials that can be used in the design of cafes.

This study aims to determine the effects of three different carrier system materials (laminated wooden beams, post-tensioned concrete beams and steel beams) used widely in interior spaces on the perceptual evaluations of respondents.

The large opening Olympic swimming pool space was chosen as the research environment. A total of 376 university graduates participated. After experiencing the 360-degree virtual images of the experimental spaces, a “spatial perception” questionnaire was applied to these respondents.

The spaces using the laminated wood beams in the carrier system were perceived as warmer, lighter, more attractive, more spacious, more informal, closer, more well-planned, freer, simpler, more peaceful, more exciting, and uncrowded compared to the spaces that used post-tensioned concrete beams and steel beams. The architect respondents made more negative perceptual evaluations for all the adjective pairs compared to the respondents in the other professional groups. Respondents who were males, and in the 26–35 years of age group, perceived more positively the physical environmental factors of the virtual swimming pools compared to females, and the 36 years of age or above age group.

The results set forth that the structural elements of buildings, such as ceilings, walls and furnishings, were not only systematic elements used in the formation of the structure, they were also important environmental factors in the perceptual evaluation of the space.

The purpose of this paper is to determine the effects of environmental factors in open-plan offices with the same characteristics but with different workstation partition heights (1.10, 1.40 and 1.65 m) on perceptual evaluations of office employees.

In this research, the effects of environmental factors on employees’ perceptual evaluations in open-plan offices at the Gölbaşı Region of Ankara were measured with a detailed questionnaire. The research data were obtained from 81 employees who agreed to fill out the questionnaire and who use open-plan offices.

It was found that the office environments with 1.65 m workstation partition heights were more favorably assessed for each of the items of planning and of privacy that form the dependent variables compared to the office environments with 1.10  and 1.40 m partition heights. On the other hand, the office environments with the 1.10 and 1.40 m partition heights were more favorable for lighting items than the 1.65 m partition height office environments. In addition, young employees had a more positive tendency toward the perceptions of environmental factors, including different workstation partition heights in open-plan offices, compared to older employees.

Results of this research provide a fundamental contribution for the impact of various partition heights that have substantial implications on the perceptions of open-plan office environments. At this point, as open-plan offices have important effects on the quality of employees’ work experiences, the influence of various partition heights on the performance of employees should be emphasized in future studies. The diversity of performance (reading comprehension, calculation, design, drawing, etc.) will be an important decision.

The significant contribution of this research is that it provides valid data and makes a valuable contribution to the body of knowledge in open-plan office design.

The intent and aim of the research was to look at a particular house type i.e. a terraced house with four floors, which is one of the popular designs commonly used in the last ten years in mass housing projects in Turkey. There are four alternatives of the type related with the cross-sectional relationship with the ground floor level. Emphasis was placed upon the "semi-cellar type" assuming that even though the level of residential satisfaction gradually increases with the possibility of interpreting the use of the open-plan floor space, and by proposing new design elements to create more adaptable and flexible spaces, the users may still experience dissatisfaction with designs where the space cannot be revised. With the use of a questionnaire, participants judged their own house as a whole and evaluated its uses for different functions and activities, complained in respect of changes required, and finally outlined their plans for the future. Despite the high level of satisfaction with having a garden (a unique characteristic in apartment-saturated Ankara), the aspect of dissatisfaction mostly referred to was the kitchen-garden relationship (or lack thereof). The residents, especially the older ones, were generally dissatisfied with the multi-storey design of their house. They prefer to remain on the backyard level without changing floors in different seasons. Besides, the users spending the longest time in the house complained more than the others and the people spending variable time in the house stated that they preferred to change the floors in different seasons. As compared to larger families, the smaller families were more likely to change floors.

This paper aims to focus on determining the effects of location of closed offices on the front facade, rear facade and side facade plans and the indoor layout (left and right users’ cabinets) on perceptual evaluations of users of physical environmental factors.

For this purpose, the responses of 54 academic users who use the Gazi University Technology Faculty Taskent Building offices were taken with the help of a survey.

As a result, it was determined that office users on the front and side facades generally perceived more positively the offices’ environmental factors than office users on the back facade. In addition, it was determined that offices with storage cabinets located to the right of users (Type A) were perceived more positively than storage cabinets located to the left of users (Type B). On the other hand, it was determined that users between the ages of 25–45 who used closed offices generally perceived the physical environmental factors of offices more positively than users between the ages of 46 and 65.

Especially the location of the building, the landscaping, the plan of the rooms and the landscape to which they are directed are major design decisions that cannot be controlled by employees. Therefore, it is necessary to know the positive/negative effects that may occur during use before making design decisions.

This paper aims to explain the relationship between sukuk market and economic growth. In this context, the study investigates the impact of sukuk market development on economic growth for nine countries (Brunei, Indonesia, Jordan, Kuwait, Malaysia, Nigeria, Saudi Arabia, Pakistan and Turkey) which have Islamic finance and banking system.

The study analyzed the data of nine countries as Brunei, Indonesia, Jordan, Kuwait, Malaysia, Nigeria, Saudi Arabia, Pakistan and Turkey for periods between 2014Q1 and 2017Q4. As a part of gross domestic product, total sukuk export measured by the sukuk market and the sukuk density which was considered as annual sukuk export per country were used to determine sukuk market development. Inflation, trade deficit and financial stress series were used as control variables.

It was determined that there was a long-term cointegrated relationship between sukuk market development and economic growth. Sukuk volume and sukuk density had a positive effect on growth in the long run. One unit increase in sukuk volume increased growth by 0.5%, while increase in sukuk density increased growth by 1.7%. According to short-term relationships, it was seen that sukuk variables did not have an effect on growth. However, sukuk exports contributed positively to growth rates in the long run.

The findings of this study are limited with nine countries (Brunei, Indonesia, Jordan, Kuwait, Malaysia, Nigeria, Saudi Arabia, Pakistan and Turkey). Also, the accessible data of sukuk market was used and the periods of 2014Q1–2017Q4 was analyzed in a study. Accordingly, future studies can find different results for different countries which has Islamic finance and banking system for different periods in the global market.

This study provides empirical findings to the related literature, and it proves that sukuk market development contributes positively to the economic growth of countries including Islamic finance and banking system in the long run.

The purpose of the study is to examine the relationship between the COVID-19 pandemic and international student mobility from an alternative perspective and to reveal descriptive findings.

This study follows qualitative research methodology. In accordance with the purpose of the study, the data were collected by the literature review and then it was analyzed by the descriptive analysis method. The effect of the COVID-19 pandemic on international student mobility and the relationships between these variables are explained by tables and classifications.

According to the findings obtained, the restrictions in physical student mobility and shutdown are observed as the biggest challenges that occurred in higher education during the COVID-19. On a global scope, international student mobility has experienced a major break. Physical campus life is still on standby. Online higher education does not give any campus life as before. Students cannot benefit form city's or country's facilities when studying online at home country. The collaboration between university and business has been declined and this is even more discouraging for international students. The hybrid education model produced an intermediate solution in this period. On the other hand, the rise of online education has created new techniques for higher education. University students who cannot go abroad attend different countries lectures and education programs. But also a new challenge has come as the access of online platforms in under developing countries university students. Online education system also discussed in terms of creating inequality in higher education.

This study focused on student mobility and not focused about academic mobility.

It is seen that the traditional higher education system has been adapted into online distance higher education system since COVID-19 crises began globally. On the other side, it is observed that most of studies have focused the effect of COVID-19 on university students based on the transition to online education. When considering the effect of pandemic process on the mobility of international students and higher education, the authors can suggest policy makers to develop new higher education protocols and teaching models supporting key issues (economic, social, health, education and equalization) in the long-term. Higher education institutes have been able to produce creative and innovative solutions for both education and communication during the pandemic process.

University students who cannot go abroad attend different countries lectures and education programs. But also a new challenge has come as the access of online platforms in under developing countries university students. Online education system also discussed in terms of creating inequality in higher education.

This study provides a new perspective for international student mobility in the context of COVID-19 pandemic. This is an emerging issue for the literature. This study is original with its approach to the subject from a global perspective through reviewing the studies of different countries. This study points out key variables for determining the effect of COVID-19 on international student mobility for future studies. When employing quantitative research models, the current key variables can guide them.

This study aims to explain the role of health on economic growth for OECD countries in the context of sustainable development. Accordingly, the study investigates the relationship between health and economic growth in OECD countries.

This study employed cluster analysis and econometric methods. By cluster analysis, 12 OECD countries (France, Germany, Finland, Slovenia, Belgium, Portugal, Estonia, Czech Republic, Hungary, South Korea, Poland and Slovakia) were classified into two clusters as high and low health status through health indicators. For panel threshold analysis, the data included growth rates, life expectancy at birth, export rates, population data, fixed capital investments, inflation and foreign direct investment for the period of 1999–2016.

The study determined two main clusters as countries with high health status (level) and low health status (level), but there was no threshold effect in clusters. It was concluded that an increase in the life expectancy at birth of countries with higher health status had no significant impact on economic growth. However, the increase in the life expectancy at birth of countries with lower health status influenced economic growth positively.

This study used data that including period of 1999–2016 for OECD countries. In addition, the study used cluster analysis to determine health status of countries, and then panel threshold analysis was preferred to explain significant relations.

This study showed that the role of health on economic growth can change toward country groups as higher and lower health status. It was proved that higher life expectancy can influence economic growth positively in countries with worse or low health status. In this context, developing countries, which try to achieve sustainable development, should improve their health status to achieve economic and social development at the same time.

This study aims to investigate the working way of the e-Pulse portal in Türkiye as a sample of a next-generation digital tool for health data management. Accordingly, this study focuses on explaining the structure and key services of the e-Pulse portal in the context of health data management.

This study is a technical paper that will explain how the e-Pulse portal works in Türkiye. Accordingly, the data are based on secondary sources and mostly the official website of the e-Pulse portal. As a sample case, this study investigates the e-Pulse portal from Türkiye. The data are categorized by tables, and some key factors are classified based on review results.

As a result of the review of the e-Pulse portal's sample account, it is seen that the e-Pulse portal provides comprehensive data for personal health data for both individuals and healthcare professionals. By permitting healthcare professionals, users or patients can share their personal health data on specific dates and numbers whenever they need and want. When sharing recorded personal health data, citizens or patients can get more efficient healthcare service on the time.

By giving descriptive evidence and review through the e-Pulse portal, countries with high-populated can see the key e-services and elements to manage health data through digital tools. On the other side, this study has some limitations. This study investigated the e-Pulse portal and its e-services for Türkiye and gave some findings mostly based on subjective deduction. Another digital portal can give different findings for the literature.

Based on the e-Pulse portal case, it is determined that by creating a digital portal with recorded personal up-to-date health data, healthcare services can be ensured more efficiently among high-populated countries in the long term. While population growth and pandemic possibilities such as COVID-19 increase throughout the world, serving more patients with these portals will increase efficiency and service quality, provided that patient information is well protected.

This study reveals key e-services and segments to provide personal health data management by a next-generation digital tool based on the e-Pulse portal. The main contribution of this study is expected to guide other countries when adapting next-generation technology or systems to manage health data in the future.

This study aims to explore the key factors in achieving an efficient e-government portal management system from a citizen perspective. Accordingly, this study focuses on explaining how an e-government portal should manage its digital public services for citizens efficiently.

This study employs a qualitative research design. As a sample case, this study preferred to analyze the Turkish e-government portal. The data is based on available open access data and information from the Turkish e-government portal, which is called e-Government Gateway in practice. In addition, the data of TURKSTAT (Turkish Statistical Institute) were used to determine the general profile of citizens about Internet skills and usage. Then, the data is analyzed by descriptive content analysis.

As a result of descriptive findings, user type, digital platform options, security and access options, and digital public service classification are all found as important factors for providing a well-designed e-government portal system from a citizen perspective. Especially, citizens should be informed about using options and service categories and types to be accessed by the e-government portal. Social media tools are efficient factors when informing citizens about the e-government portal and communicating with them.

This study provides an original model to explain how the Turkish e-government portal works from a citizen perspective. However, there are some limitations to the study. The findings and suggestions are based on the Turkish e-government portal and its digital public service management. Also, this study evaluates the efficiency of the e-government portal management from a citizen perspective. Future studies can investigate e-government portal management for different countries by different approaches or research designs.

Based on the Turkey case, it is determined that creating an e-government portal with having up-to-date public services, including both web-based and mobile-based platforms, will support the adoption and use of e-government portals.

The digital transformation of government is almost the main issue for policymakers in the world. But, this transformation process has some risk factors as well as challenges. To overcome these challenges, policymakers should design flexible and adaptable digital portals and systems to provide easy-to-use and self-use options for the citizens.

This study reveals key factors for efficient e-government portal management by providing descriptive evidence from Turkey. The main contribution of this study is expected to give practical implications and to guide other countries about the adoption of efficient e-government portals by citizens.
