Abstract
Purpose
Because of the increased use of robots in the industry, it has become inevitable for humans and robots to be able to work together. Therefore, human security has become the primary noncompromising factor of joint human and robot operations. For this reason, the purpose of this study was to develop a safe human-robot interaction software based on vision and touch.
Design/methodology/approach
The software consists of three modules. Firstly, the vision module has two tasks: to determine whether there is a human presence and to measure the distance between the robot and the human within the robot’s working space using convolutional neural networks (CNNs) and depth sensors. Secondly, the touch detection module perceives whether or not a human physically touches the robot within the same work environment using robot axis torques, wavelet packet decomposition algorithm and CNN. Lastly, the robot’s operating speed is adjusted according to hazard levels came from vision and touch module using the robot’s control module.
Findings
The developed software was tested with an industrial robot manipulator and successful results were obtained with minimal error.
Practical implications
The success of the developed algorithm was demonstrated in the current study and the algorithm can be used in other industrial robots for safety.
Originality/value
In this study, a new and practical safety algorithm is proposed and the health of people working with industrial robots is guaranteed.

Abstract
Purpose
As more and more robots are used in industry, it is necessary for robots to interact with high dynamic environments. For this reason, the purpose of this research is to form an excellent force controller by considering the transient contact force response, overshoot and steady-state force-tracking accuracy.
Design/methodology/approach
Combining the active disturbance rejection control (ADRC) and the adaptive fuzzy PD controller, an enhanced admittance force-tracking controller framework and a well-designed control scheme are proposed. Tracking differentiator balances the contradiction between inertia and jump control signal of the control object. Kalman filter and extended state observer are introduced to obtain purer feedback force signal and uncertainty compensation. Adaptive fuzzy PD controller is introduced to account for transient and steady state performance of the system.
Findings
The proposed controller has achieved successful results through simulation and actual test of 6-axis robot with minimum error.
Practical implications
The controller is simple and practical in real industrial scenarios, where force control by robots is required.
Originality/value
In this research, a new practical force control algorithm is proposed to guarantee the performance of the force controller for robots interacting with high dynamic environments.

Abstract
Purpose
The aim of this study is to question the relationship between architectural ethical codes and faults in earthquakes. Earthquakes have devastating effects on all societies in history and today. And the relationship and importance of the architect and building, one of the most important roles of these destructive effects, is once again revealed in every earthquake. Although there are some restrictions or warnings for architects and the architectural profession to reduce this destructive effect in many regulations and ethical codes, it is possible to see the defects caused by architectural design and the destruction caused by these defects in every new earthquake.
Design/methodology/approach
In this study, the most destructive earthquakes in Turkey in the past 20 years (Bingöl, Van, Elazig and Izmir) and the 1999 Marmara earthquake, which was the most destructive earthquake in Turkey’s recent history, and the damages occurred in these earthquakes and their causes were examined. Although the scope of the study is “destructive earthquakes that have occurred in the past 20 years in Turkey”, the Marmara Earthquake, which occurred in 1999, when the destructive effect of the earthquake was seen the most and architectural design errors were intense, was also included in the scope of the study. And to have a more comprehensive understanding of how these defects are examined in terms of ethical codes and to make a more comprehensive comparison, ethical codes from different countries in the world have been researched and a review has been made on topics such as public welfare, human rights and raising the standard of the profession.
Findings
This study concludes by reviewing the key factors learned from the examined ethical codes of different countries. Finding ethical codes of different countries was challenging to gain approval. In addition, the study ends with recommendations in terms of questioning the regulations and education curriculum relations on a country basis.
Originality/value
This study, which targets architect candidates who carry out the profession of architecture and continue their architectural education, evaluates the architectural design flaws seen in earthquakes through ethical codes and forms a basis for further studies.

In this paper, we explore the impact of land management practices on post-disaster housing, to draw lessons from the case of reconstruction in Türkiye.
Abstract
Purpose
In this paper, we explore the impact of land management practices on post-disaster housing, to draw lessons from the case of reconstruction in Türkiye.
Design/methodology/approach
We conducted two qualitative case studies of two reconstruction experiences following the 2020 Elazığ and İzmir earthquakes. We analyzed 70 articles, technical reports and press releases and then used a set of policy analysis tools to examine five policy documents in depth. Finally, we wanted to understand how key officers interpreted these policy documents, so we closely analyzed the transcripts of eight semi-structured interviews.
Findings
Türkiye’s legal framework comprises five main policies that concentrate power in the central government and are not tailored to post-disaster reconstruction. This framework facilitates the construction of rubber-stamped apartment buildings, which disregard cultural and social contexts and practices. The current reconstruction policy neglects alternative options like cooperative housing, which could better respond to communal needs and expectations. It also often leads to the loss of land rights among affected residents.
Research limitations/implications
We only analyzed decision-making processes in two case studies and based our study on a limited number of interviews. Therefore, it is difficult to generalize our results and apply them to other contexts. Further quantitative and qualitative work is necessary to conceptualize the links between land management and post-disaster housing reconstruction.
Practical implications
Our findings suggest a need for legislative frameworks specifically designed to address land management during post-disaster reconstruction. The concentration of power in central governments is problematic, thus it remains crucial to empower local authorities by reinforcing technical expertise and facilitating administrative autonomy.
Originality/value
This study offers unique insights into how power relations influence land management practices in post-disaster housing reconstruction. Examining the centralization of power and its impact on cultural and social practices identifies common forms of dispossession and points to key areas for policy improvement.

Abstract
Purpose
Despite the quantity of collaborations, the vocational network of the housing production in Ankara during its first five years (1923–1928) remains dispersed. The aim of this study is to identify all the actors of housing production and their collaborations which shaped Ankara's urban development as the new capital city.
Design/methodology/approach
The study engages with the literature and archival documents to identify the actors of the housing production, i.e. architects, master-builders, public institutions, private companies, contractors and entrepreneurs, and their resultant vocational network in the housing production in Ankara during 1923–1928.
Findings
Due to different agendas, such as speculation, financial interests or patriotism, the construction industry in Ankara had become an arena where many paths intersected, forming an intertwined vocational network. The profession of contractor became popular, and local architects, engineers and even individuals of various other professions began to work as mediators for foreign companies and public institutions, which required support especially in large-scale projects.
Originality/value
The dispersed information revealed that the actors of the housing production remained mostly anonymous, or only the famous architects were commemorated; however, others could be found within the lines of the established literature on Ankara and/or in archival documents. This research not only focuses on “salient” actors but also highlights the “silent” actors of the housing production and prepares charts to clarify the vocational network in Ankara during its first five years to contribute to the future studies on Ankara and its housing.

Abstract
Purpose
The aim of this study is to investigate the usability of horsetail, sunflower stalk, wheat stalk and corn stalk ashes as additives in paints and their performance against corrosion resistance when used.
Design/methodology/approach
The ashes of horsetail, sunflower stalk, wheat stalk and corn stalk were investigated in this study in single, binary and ternary combinations with three different percentages as additives in paints. Samples of concrete with any combinations of ashes resisted against the corrosion of steel reinforcements, but horsetail ash proved to be the most effective.
Findings
It can be said that these research results show that the paint containing horsetail ash is an excellent coating material that can be used in paints for the corrosion resistance of steel in reinforced concrete. The corrosion rate decreased with the increase in the amount of reactive SiO2. There was less mass loss with the formation of resistance against corrosion in the horsetail ash added concretes. That is why horsetail ash is one of the most effective options for the aforementioned purpose.
Originality/value
Being cheap and easily obtainable, the materials used for coating in this study are perfect candidates for industrial use.

Abstract
This chapter presents findings of an ongoing project on the social construction of ethnic identity among young Kurdish immigrants living in Turkey. The chapter begins with information on Kurdish culture. The second part overviews the difficult relations between the Turkish state and Kurds since establishment of the Republic in 1923. The third section describes the education system in the country and in Istanbul specifically. Historical ties between the Istanbul and Kurdish culture are also mentioned. The chapter closes with research that focuses on problems of Kurdish educational experiences in Turkey and preservation of their cultural identity in Istanbul. The study shows that on the one hand public education is perceived by the Kurds in Turkey as a discriminatory entity but on the other hand nonpublic educational opportunities in Istanbul help Kurdish migrants preserve and practice their cultural identity.

Abstract
This chapter addresses the impact of gendered social capital in developing countries to understand the barriers and opportunities to women's entrepreneurship with social capital development and also to examine factors influencing the development of social capital for women and how the identified factors benefit the creation of their entrepreneurial activities. This study follows a systemic literature review to achieve the purpose of the research by examining the selected articles in both English and Turkish, followed by factor comparison between developing, developed countries, and world datasets obtained from Global Entrepreneurship Monitor (GEM) database. The finding shows that social capital strongly impacts the entrepreneurial activities among women entrepreneurs in developing countries, especially in Turkey. Although the academic and practical studies on this field were started about two decades ago in Turkey, it has faced a radical increase in last 5 years and many practitioners and scholars working on these concepts. The clusters in English and Turkish resources are almost the same; however, the density and number of key terms are much lower in Turkish literature which shows a gap for Turkish researchers to publish more in this field to examine variables for better view about women entrepreneurship and social capital related to it.

This study aims to reveal the mediating role of patient satisfaction on the impact of relationship marketing on hospital loyalty.
Abstract
Purpose
This study aims to reveal the mediating role of patient satisfaction on the impact of relationship marketing on hospital loyalty.
Design/methodology/approach
The scale questionnaires used in the study was the Relationship Marketing, Hospital Loyalty and the Patient Satisfaction Scale. The population of the study is made up of the patients who received in-hospital services in private hospitals operating in Kocaeli province. The field study was conducted between August 1 and October 31, 2019. After determining the sample size, the study was conducted on 401 patients in private hospitals primarily using the purposive sampling method. Descriptive statistics, correlation analysis and statistical package for the social sciences Process Macro were used to analyze the data.
Findings
According to the findings of this study, patient satisfaction has an effect on hospital loyalty. Relationship marketing has an impact on hospital loyalty, and this effect is further enhanced by patient satisfaction. In other words, patient satisfaction has a mediating role in the impact of relationship marketing on hospital loyalty. Relationship marketing plays an important role in creating hospital loyalty and patient satisfaction. For this reason, it is recommended that health institutions adopt relationship marketing practices. Hospital loyalty and patient satisfaction will be ensured through relationship marketing. This will allow the health-care institution to continue to exist and to be more advantageous than other institutions.
Originality/value
The uniqueness of the paper lies not only in the only regression findings but also in the methodology used to capture the impact of the lagged effect of marketing relationships on hospital loyalty. Specifically, a regression model is based on both direct and indirect effects.

This study aims to investigate whether changes in consumer interest rate, exchange rate and housing supply have permanent effects on housing inflation in Turkey.
Abstract
Purpose
This study aims to investigate whether changes in consumer interest rate, exchange rate and housing supply have permanent effects on housing inflation in Turkey.
Design/methodology/approach
For this purpose, data from 2010M01 to 2020M06 and changes in consumer interest rate, exchange rate, housing supply and housing inflation were used. Relationships between variables are analyzed first by the Granger causality tests and then the conditional frequency domain causality tests. The conditional frequency domain causality test specifically reveals the permanent causality between variables, whether there is a permanent effect.
Findings
According to the Granger causality test results, there are causality relationships from changes in the consumer interest rate and exchange rate to housing inflation. However, there is no causality relationship between housing supply and housing inflation. According to the conditional frequency domain causality test results, there is causality for the permanent and mid-term from changes in the consumer interest rate to housing inflation and causality for the mid-term and temporary from changes in the exchange rate to housing inflation. Additionally, it was found that there are causality relationships between changes in the consumer interest rate and changes in the exchange rate.
Research limitations/implications
The first limit of the study is that only 2010M01-2020M06 months can be considered. Because the date that variables started common is 2010M01. Besides, there is a limit in the study in variables used. Many variables, both micro and macro, can be added to affect housing inflation.
Originality/value
Housing inflation is a remarkable issue in Turkey. There is an increase in the number of studies on the subject in recent years. For this reason, the study is trying to contribute by approaching the subject from a different angle. The most important contribution of the study is that it has not been investigated whether the determinants of housing inflation have permanent or temporary effects, which were not done in previous studies. In addition, the method used reveals how many months the effects of changes in exchange rates, consumer interest rates and housing supply on housing inflation last. Based on the findings obtained from the methods, important economic and political implications have been put forward in depth.
