1. Introduction
Public spaces including urban parks and plazas are universal leisure facilities where people spend a lot of time, and their functions are very diverse. Public spaces play a role in managing the health of people, such as operating various leisure programs, volunteering, and exercising. As the scenery of the public life, these places are of prime significance in various fields of study in urbanism and the history of city planning [
1,
2]. Various types of public spaces are significant elements of any habitable, sustainable urban development [
3,
4,
5]. The concept of a public space raises different functions of outdoor public assembly spots [
6,
7] and neighboring spaces between buildings [
8,
9]. Key examples of public spaces in urban areas are cafes, retail bazaars, theme parks, streets, and pedestrian walkways [
10,
11,
12]. Due to these various functions, high-quality public space is positioned as a crucial system in our society in improving the quality of life of people.
However, the COVID-19 pandemic, which has been going on since early 2020, is having a huge impact on our lives. Preventive measures against infectious diseases that have never been experienced, such as social distancing and wearing masks, had to be implemented in daily life. As this situation continues, members of society of all ages are having a hard time enduring various types of difficulties [
13]. These difficulties are particularly evident in public spaces. Restrictions on the use of public spaces are one of the key policy measures to reduce the spread of COVID-19 and protect public health [
14,
15]. In other words, in a pandemic environment, public spaces often limit service provision and are repeatedly closed for a certain period of time. As the media and many scholars have already pointed out, there has been widespread recognition that the COVID-19 pandemic would demand a New Normal and will completely change the flow of world civilization [
16].
Most of the preceding research on COVID-19 has been limited to establishing an infectious disease response system in the health sector. These studies mainly related to the quarantine method, monitoring system and information sharing, epidemiological investigation, diagnostic testing, crisis situation determination and response process, preparation and response for infectious disease management in medical institutions, and local responses [
17,
18,
19]. Moreover, in the medical field, research on infectious disease mechanisms, treatment technologies, vaccines, diagnostic technologies, surveillance epidemiology, and infrastructure construction are being carried out [
20,
21]. When it comes to infectious diseases, policies aimed at reducing social contact and limiting mobility have been used for centuries [
22,
23,
24]. Movement has been shown in numerous studies to influence disease transmission and incidence [
25,
26]. Therefore, most of the studies on the interrelation between the pandemic and spatial aspects aim to measure the level of social interaction and mobility for a large population in a large geographic area and then quantify its transmission rate and impact. To date, various studies worldwide have researched COVID-19 using geographic information systems (GIS), which focused on spatiotemporal analysis, data mining, environmental variables, and health and social geography [
27,
28,
29].
As social distancing measures are vital part of mitigating pandemics [
30], planners, designers, architects, landscape designers, and journalists are already predicting and studying how this crisis will change the interactions between people in public spaces [
15,
31]. In a pandemic situation, employees of public space are members of organizations who play an important role in providing services in accordance with the government’s quarantine guidelines. So far, there have been a few studies regrading employees’ physical health, but no concrete studies on the perception of their workspace and the workload for which they are responsible. They may experience various social, psychological, health difficulties, and conflicts as they have to take on the role of supporters in managing visitors on the front line from the risk of an infectious disease they have never experienced before. However, as mentioned above, most of the studies related to infectious diseases have been conducted as large-scale and quantitative studies. Measuring and quantifying the level of social interaction and mobility for large populations over large geographic areas is often not feasible. Thus, the purpose of this study is to derive the subjective perception about COVID-19 of public space employees and to identify the characteristics of COVID-19 related issues. To this end, Q-Methodology, which is a useful analysis method for measuring the subjective perception on a specific topic [
32,
33], has been used in this study. In particular, we posit the preparation in relation to policy development for public space management by examining the perception of workers in public places about COVID-19 in the process of coping with the pandemic.
2. Public Space and Psychological Distance during the Pandemic
Recent studies have shown that access to urban spaces has positive effects during the situation of social distancing [
34,
35]. Therefore, in order to accurately predict the user pattern of public spaces in the post-pandemic era, it is necessary to understand the factors affecting outdoor activities due to the pandemic at the level of individuals who are consumers and providers of outdoor activities.
Historically, public spaces have been regarded as timeless, transformative, and elusive entities for a city’s urbanism [
36]. A public space that reflects a wider society [
37] has been perceived as providing different functions to users in different ways; this became a precursor in questioning the public space beyond a concept of singularity [
38]. It is critical to first take into account the conscious structuring of places in an attempt to minimize unsettling encounters with people who could threaten the accepted narratives of a specific place [
39]. In addition, the ways that public spaces are inclusive and exclusive at the same time presents a paradoxical situation. For example, public spaces can be relatively more accessible while being more closed, depending upon the individual and the associated public.
Before COVID-19, the discussion around the term
public space led to definitions that captured various characteristics. Definitions of public space evolved around considerations of ownership [
39], human behavior [
40], the democraticness and responsiveness of places [
41], and accessibility [
42]. Seemingly shared and accessible public open spaces have been replaced by more orderly places exposed to control, power, exclusion, and inaccessible narratives [
39,
43,
44,
45,
46]. Uncertainty of diversity, urban spontaneity, and captivation of urban flavor have been replaced by expectations and knowledge of the quality of the urban environment. This is a cumulative result of a planning and governance structure that responds (or fails to respond) to deeper structural changes occurring in society [
47].
However, COVID-19 has significantly highlighted the lack of accessible and usable public space. Continuous development trends have deprived people of adequate local public spaces or suitable alternatives in their homes, including semi-private or semi-public spaces [
48].
The low proximity between social actors in an urban environment is a natural side effect of increasing urban density, and in return, it appears to be associated with the spread of infectious diseases [
49]. In this regard, urban morphology has been shown to influence the spread of COVID-19 in a variety of ways, for example, access to open spaces [
50]. Obviously, the transmission of COVID-19 has a strong proximal dimension as it requires close personal contact [
51]. Therefore, effective policies for social distancing come from changing social norms or limiting activities in public spaces where reduction in personal distance is inevitable.
During the COVID-19 pandemic, most people isolated themselves from physical contact while working from home, using digital connections, and using digital public spaces to maintain social distancing [
52]. Most people have shifted from the traditional way of working to a “do it yourself in the living room” approach, where the home is now a production space where workshops are organized to perform work tasks and duties. Salama [
30] maintains that currently we are in a transition period called the ‘new normal’, which will eventually become a stable condition of the actual normal. However, from a psychological point of view, social distance is classified as a type of psychological distance [
53,
54]. Psychological distance refers to how close an object is psychologically to the now, here, or self. Types of psychological distance include temporal distance, spatial (or spatial) distance, social distance, and virtual (or probabilistic) distance [
53]. In this psychological distance, differences lead to differences in responses to objects. For example, people’s perception of global warming was different when they heard that a natural disaster related to global warming occurred in their area. [
55,
56,
57,
58,
59]. Therefore, examining public space employees’ perceptions of COVID-19 could be a way of seeing the psychological distance to COVID-19. In addition, this may provide a clue for the direction of the space operation program in the post-COVID-19 era.
3. Methodology
3.1. Q-Methodology
This study used the Q-methodology to identify and categorize the subjective perceptions of COVID-19 workers in public spaces. The Q-methodology is one of the factor analysis methods in which the unit of analysis becomes a human and groups people with similar response patterns. In particular, this method is suitable for this study in that it is a method for objectively measuring values, beliefs, attitudes, etc., which can be regarded as the subjective domain of human beings, in that a more objective approach to the domain of human subjectivity is possible. In other words, in objectifying subjectivity, it is a method of gathering people who have similar reactions to a specific object or issue and confirming the contents of these people’s reactions.
3.2. Q-Statements
The Q-Statement is a statement that is representative of the research topic and functions similarly to the scale of quantitative research. Q-Statements refer to the totality of feelings and opinions shared within a culture as the sum of all subjective statements that each individual can communicate about a research topic [
60,
61]. Q-Statements collection can be accomplished by mobilizing various methods, for example, the researcher contacts people related to the research topic and conducts an in-depth interview or reviews various types of literature related to the research topic [
60].
In this study, Q-Statements were selected by conducting in-depth interviews and literature research on public space workers. In-depth interviews were conducted with five urban park managements using unstructured open-ended questions. Based on the results of these in-depth interviews and literature review, a total of 98 questions directly and indirectly related to the response of public spaces workers to COVID-19 were derived as the first statement. Among the first statements, similar or duplicate items were deleted and merged, and 55 items were extracted secondly, and after verification by two professors of landscape architecture, 32 items were finally selected as a Q-Statements. The 32 Q-Statements are shown in
Table 1 below.
3.3. P-Sample
The P-Sample means selecting the research subjects who will respond to the Q-Sample. Since the Q-Methodology aims to grasp the subjective perception of a specific topic rather than the generalization of the research, the subjects related to the research purpose are generally composed of the P-Sample [
62,
63].
In the Q-methodology, the P-sample is based more on the depth of experience and information on the research question than on the representativeness of the population [
61,
64]. Therefore, in this study, it was considered that the workers related to public space programs were appropriate for analysis in that they had a relatively comprehensive understanding of public space management. The sampling method was snow-balling. This is a strategy mainly used by researchers to increase social access to upper echelon research subjects. On the other hand, the disadvantage of this method is that members in the human network based on friendship can maintain homogeneous values and perspectives. In order to control this, the researcher explicitly revealed these issues to the research subjects during the sampling process and asked them to direct individuals who are connected based on formal-functional relationships rather than acquaintances. The sampling results are presented in
Table 2 below. In consideration of the social sensitivity of the research subject, the study subjects were anonymized, and only the minimum identification information meaningful to the study was disclosed. Therefore, this study consisted of 24 workers in four public spaces located in Blacksburg, Virginia in USA as a P-Sample. Although the number of P sets was small, major actors from the public spaces were generally included.
All the data for analysis were collected from 13 October to 10 December 2020. The data collection was conducted by visiting each public space directly by the researcher and was conducted in compliance with the quarantine guidelines for the prevention of COVID-19. In order to comply with research ethics, the purpose of the research was fully explained before the investigation, consent to participate in the research was obtained, confidentiality of personal information, free participation in research, and guidance on Q-Methodology were individually implemented.
When examining the characteristics of the P-Sample participating in this study, focusing on gender, age, and work experience, the gender was found to be 61.6% female and 38.4% male. By age group, 21.7% were in their 20s, 43.5% in their 30s, and 30.4% in their 40s.
3.4. Q-Sorting
Q-Sorting is the process of classifying the subjects according to the degree to which they agree or disagree with each Q-statement. This process focuses on how the entire item is distributed to each individual rather than for or against a specific item. One can arrange the samples according to the relative importance of the Q-Statements. There are two types of Q-Statements classification methods: the free distribution method, which is arbitrarily classified by the research subjects, and the forced distribution method, which usually presents the classification framework in the form of a normal distribution [
33,
65]. This study was classified according to the forced distribution method. First, the subjects of the P sample read each statement card and grasped its contents, and then, in a broad framework, were first classified into three groups: disagree, neutral, and agree. Finally, the Q-Statements were arranged to have a distribution as shown in
Figure 1 below, and after classification, the reasons for choosing each of the two statements with the most agreement or the most disagreement were specifically stated.
3.5. Q-Analysis
The stage of analysis in the Q-method refers to the stage of categorizing individuals according to the degree of cognitive similarity through the scores surveyed based on the responses of the questionnaire discussed above, and capturing features or finding correlations based on the typed results [
61,
62,
66]. The response values given to the questions were integer values ranging from −4 (most negative) to 4 (most positive). In previous studies, values ranging from –5 to +5 were often used, but since the number of questions (N = 32) used in this study was relatively small, the range of response values was reduced to control outliers in the results.
The PQMethod analysis program (ver 2.35) was used for typing and correlation analysis, and correlations and factors of items were analyzed by varimax rotation. The researcher gave appropriate labels to the clusters of the types that appeared as a result of the analysis to intuitively indicate the classification and characteristics between the groups. Response values corresponding to each type were standardized and replaced with a ‘Z-Score’, and their intensity was measured as an indicator of the relative distances in which the responses were distributed. Because Z-Scores have a standardized distribution, they provide a standardized framework for comparing the strengths of each response value in comparisons between types. In the interpretation of the results, it was necessary to accompany the process of supplementing the interpretation based on the fact that response results with factor weights of 1.00 or more usually contain singularities. Thus, each comment (follow-up interview) was received from the participants for the statements placed at both ends, and the contents of representative comments were used as quotations if necessary to help the reader understand.
5. Discussion
All three types recognized that when a confirmed case occurs in public space, the right and safety of users or communities to know is crucial, and accurate information must be provided as it is necessary to prevent the spread of infection. Above all, these results show other sides of the COVID-19 situation as the participants of this study are currently in charge of various tasks such as quarantine and service provision in public spaces. In seeking specific countermeasures based on these types of perceptions of workers, it is necessary to first consider the common perceptions of each type. On the other hand, for the part that shows contradictory perceptions, it is necessary to examine the regulations and circumstances surrounding public space more precisely. Based on this, specific policy recommendations for the operation of public spaces when an infectious disease such as COVID-19 spreads in the future are presented as follows.
First of all, due to the closure of public spaces and the limitations of service provision due to COVID-19, users who regularly visit public spaces for the purpose of exercise face various difficulties such as physical, psychological, and daily life. In particular, since this deteriorates the health and quality of life of the vulnerable, such as the elderly [
67,
68], it is necessary to establish a safe and stable service provision system even in the case of an infectious disease. In other words, in the event of an infectious disease outbreak, specific measures should be prepared so that the service can be safely and stably provided, rather than a total service cessation. In particular, since the elderly gain vitality from meeting and talking in public spaces and checking each other’s safety, face-to-face services as small as possible should be provided while complying with infectious disease-related regulations. For this, it is necessary to consider how to organize operating costs, subdivide labor, or restructure staffing as needed.
Secondly, the current operating guidelines for public spaces do not presuppose the situation of infectious diseases. Therefore, taking into account the opinions of the medical community who are concerned about the continued occurrence of infectious diseases [
69,
70], it is necessary to prepare operational guidelines and evaluation guidelines suitable for the situation and conditions of public spaces that can respond to infectious diseases in the future. In an existing study, an Australian case presented a manual on procedures, education and worker training, and a monitoring system to provide care to clients at the time of MERS [
71], and the elderly at home in response to this COVID-19 As in the case of the publication of rules for providing meal services for children [
72], specific operational guidelines and appropriate public space evaluation guidelines should be prepared so that public spaces can provide services even in an infectious disease situation. In addition, as the provision of non-face-to-face services such as phone safety checks increases, work standards for telecommuting, etc., should be revised together.
Thirdly, it is necessary to prepare an integrated face-to-face and non-face-to-face welfare platform to respond more actively to COVID-19. One of the methods of providing services in public spaces in response to infectious diseases is the provision of non-face-to-face services using IT technology [
72,
73,
74]. To this end, access to media should be strengthened for users and workers in public spaces, and not only equipment and facilities for online education should be reinforced, but also online utilization capabilities should be improved. In particular, since digital access is weak in the case of the elderly, it is necessary to prepare an education program to bridge the gap. In addition, it is necessary to strengthen the capacity of workers to produce and edit online videos or operate equipment, so that video production is possible in the public space itself. Therefore, it is necessary to secure the budget for these changes and to flexibly reorganize the institution.
Fourthly, programs that should be operated as face-to-face services and tasks to discover and manage target audiences must be combined. The occurrence of infectious diseases is more dangerous in vulnerable groups [
75,
76], and it is necessary to demonstrate expertise in case management for the vulnerable to minimize the negative impact of infectious diseases on the vulnerable [
75,
77,
78]. In addition, as a result of this study, some cognitive types (Type 2) suggested the need to expand physical and mental health professionals such as nurses and mental health experts from the existing social worker-centered human resources structure in public spaces. This provides a clue that it may be necessary to provide services in public spaces to reorganize the workforce structure to constantly respond to infectious diseases in the future.
Fifthly, according to the research of Northwestern University in the USA, in the correlation between vitamin D and the death rate of COVID-19, patients in countries with high mortality rates such as Italy had lower vitamin D levels compared to countries that did not. These results show the importance of outdoor programs where people can be in sunlight. Therefore, in preparation for the post-coronavirus era, it is necessary to prepare various public space programs that are not limited to indoor public space programs, but expand outdoor programs such as walking on outdoor trails taking social distancing into consideration.
Finally, to prepare for the post-COVID-19 era, a big data management system to overcome the crisis should be established. In order to properly intervene by time, target, high-risk person, and project while considering the infectious disease warning stage and the distancing stage [
79], some data on public space users must be established. This should provide individual customized services by building data on users, such as whether emergency measures are necessary according to the status of general visitors of public spaces.
6. Conclusions
This study attempted to investigate the situation of public spaces due to COVID-19 in more detail by understanding the types of perceptions of COVID-19 workers in public spaces. Based on this, we attempted to explore appropriate countermeasures for public spaces in the outbreak of a large-scale infectious disease such as COVID-19. By using the Q-method, 24 workers in four public spaces located in Blacksburg, Virginia, USA were selected as P-Sample and Q-Sorting was conducted. To summarize the study results, there were three types of subjective perception types of public space workers regarding COVID-19. Type 1 was named as ‘Expansion of Non-Face-To-Face Service’, and employees in this type perceived that they were actively and flexibly responding to the situations arousing in public space due to COVID-19. In addition, they were concerned about the worsening situation of particularly vulnerable users due to restrictions on the use of the public space. They also recognized that information about the occurrence of an infected person in the public space should be clearly communicated. Type 2 was named as ‘Expansion of Professional Labor’, and it was found that workers belonging to Type 2 recognized that medical personnel as employees in public spaces were needed above all else. As a type of person who felt that disinfection, quarantine, and office work were overloaded due to the COVID-19, they considered that a government response was necessary in consideration of the overall situation of public spaces. Type 3 was labeled as ‘Expansion of Welfare Service Type’, and they perceived that the health of visitors deteriorates due to closure of public spaces and the increase in vulnerable groups at risk are the most serious problems. While it is necessary to expand welfare services, they had a negative perception about the need for resident medical personnel or substitutes in public spaces.
This study attempted to make policy recommendations on the perception of infectious diseases for public space workers in the context of infectious diseases and the direction of service provision in public spaces based on this. By doing so, this study can be used as basic data for policy response and system improvement of public spaces in the event of an infectious disease such as COVID-19 in the future. This study also has an implication that the results provide a starting point for public spaces to provide continuous services and programs even in the case of future infectious diseases. The spread of the disease has caused a state of being classified as a new normal due to social distancing measures, and is characterized by separation, isolation, and involvement in the virtual world, which focuses on telecommuting through the use of information and communication technology. As a result of attempts to limit the spread of the disease, the acceptability of the new normal seems to be a stable state in the future, that is, a catalyst for the actual normal. While dealing with health in the post-epidemic virtual world, negative consequences appear for many people around the world to work in public spaces.
However, although this study systematically classifies workers’ perceptions of public space services in the context of infectious diseases, there is a limitation in not providing concrete and specific reasons why participants perceive them as they are. Moreover, given the novelty of COVID-19 and other factors that may impede predictions of behavioral changes (age, politics, and necessity), it is difficult to predict whether COVID-19 will lead to long-term changes in human behavior in public places [
80]. Therefore, in-depth studies that complement these limitations should be continued in the future. Another strand of qualifying studies examining the influence of infectious diseases on social interaction in our daily life should be conducted to understand the mechanism between social interaction and mobility [
81].
