Development of a new 17-item Asthenopia Survey Questionnaire using Rasch analysis

AIM:To develop the 17-item Asthenopia Survey Questionnaire(ASQ)-17 by Rasch analysis,and to generate a predictiveness score.METHODS:Totally 739 participants were recruited and 680 were involved in the result analysis in this prospective,cross-sectional study.Three rounds of Rasch analysis were used to analyze the psychometric characteristics of items and options.RESULTS:Phase 1 assessed the original ASQ-19,adjusted the item scoring mode to a four-point Likert response rating scale and combined the 18th and 19th items into a new item.Phase 2 deleted the 11th item.Phases 3 and 4 assessed the new ASQ-17.All the evaluation indexes of ASQ-17 were acceptable.The Infit and Outfit MnSq values of items were 0.67-1.48,the variance explained by the principal component and the unexplained variance explained by the first contrast were 53.90%-59.40%and 1.50-1.80 in three dimensions.The curve peaks of scores in each dimension were separated and in the same order.The PSR and PSI values were 2.80 and 0.89,respectively.The mean scores of dimensions A(9.5±4.1 vs 3.5±3.2),B(7.3±3.3 vs 2.5±2.7),C(4.3±2.2 vs 1.4±2.0)and total(21.1±8.1 vs 7.4±7.0)in asthenopia participants were significantly higher than those without asthenopia(all P<0.001).The area under the curve in two groups was 0.899(P<0.001).Youden’s index was up to the maximum value of 0.784 when the cut-off value was 12.5.CONCLUSION:ASQ-17 has stronger option sorting and suitability than ASQ-19.It is an effective assessment tool for asthenopia with an optimal cut-off threshold value of 12.5,which is suitable for diagnosis and curative effect evaluation.

Development and validation of a prediction model for early screening of people at high risk for colorectal cancer

BACKGROUND Colorectal cancer(CRC)is a serious threat worldwide.Although early screening is suggested to be the most effective method to prevent and control CRC,the current situation of early screening for CRC is still not optimistic.In China,the incidence of CRC in the Yangtze River Delta region is increasing dramatically,but few studies have been conducted.Therefore,it is necessary to develop a simple and efficient early screening model for CRC.AIM To develop and validate an early-screening nomogram model to identify individuals at high risk of CRC.METHODS Data of 64448 participants obtained from Ningbo Hospital,China between 2014 and 2017 were retrospectively analyzed.The cohort comprised 64448 individuals,of which,530 were excluded due to missing or incorrect data.Of 63918,7607(11.9%)individuals were considered to be high risk for CRC,and 56311(88.1%)were not.The participants were randomly allocated to a training set(44743)or validation set(19175).The discriminatory ability,predictive accuracy,and clinical utility of the model were evaluated by constructing and analyzing receiver operating characteristic(ROC)curves and calibration curves and by decision curve analysis.Finally,the model was validated internally using a bootstrap resampling technique.RESULTS Seven variables,including demographic,lifestyle,and family history information,were examined.Multifactorial logistic regression analysis revealed that age[odds ratio(OR):1.03,95%confidence interval(CI):1.02-1.03,P<0.001],body mass index(BMI)(OR:1.07,95%CI:1.06-1.08,P<0.001),waist circumference(WC)(OR:1.03,95%CI:1.02-1.03 P<0.001),lifestyle(OR:0.45,95%CI:0.42-0.48,P<0.001),and family history(OR:4.28,95%CI:4.04-4.54,P<0.001)were the most significant predictors of high-risk CRC.Healthy lifestyle was a protective factor,whereas family history was the most significant risk factor.The area under the curve was 0.734(95%CI:0.723-0.745)for the final validation set ROC curve and 0.735(95%CI:0.728-0.742)for the training set ROC curve.The calibration curve demonstrated a high correlation between the CRC high-risk population predicted by the nomogram model and the actual CRC high-risk population.CONCLUSION The early-screening nomogram model for CRC prediction in high-risk populations developed in this study based on age,BMI,WC,lifestyle,and family history exhibited high accuracy.

Research and Exploration of Ideological and Political Education in the Course of Pathophysiology

Course based ideological and political education (CIPE) is an important way to improve the quality of ideological and political work and talent cultivation. This study explores for the first time the implementation of ideological and political education in the teaching of pathophysiology courses, and also analyzes the evaluation of student psychological status and the importance of mental health education in the implementation of IPE courses. A survey was conducted on 211 students at Yangtze University to understand their motivation and behavior towards learning ideological, political, and pathophysiological courses. In addition, a questionnaire survey was used to explore the relationship between pathophysiology and ideological and political courses, as well as the importance of their satisfaction with the implementation of ideological and political courses in pathophysiology and mental health education. The research results indicate that factors such as educational background and gender differences affect the learning of CIPE. Graduate students are more interested in ideological and political courses, while female students find it difficult to study pathophysiology;In addition, the results of one-way ANOVA indicate that the implementation effect of IPE in pathophysiology courses depends on the level of interest in IPE and pathophysiology courses, the level of consideration for the importance of professional courses, the professional gains after studying pathophysiology, and the level of understanding of the relationship between IPE and CIPE. 81.04% of students believe that in the CIPE process, telling stories by teachers themselves is the most popular way of communication and education. This reflects the importance of mental health education from the perspective of CIPE. In addition, this study also indicates that PBL and flipped classroom teaching models are popular teaching models in CIPE. This study is beneficial for promoting the improvement and implementation of CIPE and mental health education in higher education curricula, thus providing valuable insights for educational decision-makers.

Objective: This study aimed to develop and validate a self-management ability questionnaire for patients with chronic periodontitis.Methods: A questionnaire was developed through theoretical research,literature review,semistructured interview,and expert consultation.A total of 231 patients with chronic periodontitis from the Department of Periodontics in the Stomatological Hospital of Tianjin Medical University were recruited by convenient sampling.Validity and reliability were analyzed.Results: The questionnaire consisted of 24 items.Exploratory factor analysis identified three principal factors,which explained 66.949% of the total variance.The item-level content validity was between 0.800 and 1.000,and the scale-level content validity was 0.969.The coefficient of correlation between the gold standard and the whole questionnaire was 0.869.Cronbach's α of the whole questionnaire was 0.931,and the test-retest reliability coefficient was 0.825.Conclusion: The questionnaire developed in this study satisfies the measurement standard and has good reliability and validity.It is useful for clinical work to measure self-management among patients with chronic periodontitis.

Adjuvant therapy for hormone receptor-positive breast cancer: Perspective from a survey on breast cancer physicians' acceptance of practice-changing data

A cross-sectional online survey was conducted.A high proportion of the Chinese breast cancer(BC)physician respondents(n=77)would prescribe extended adjuvant endocrine therapy(AET)with aromatase inhibitors(AI)beyond 5 years for postmenopausal females with BC,especially those with higher risk.Respondents with≥15 years of clinical experience were more likely to prescribe a longer duration of AET for low-risk patients.Half of the respondents considered intermittent letrozole as an acceptable option.Most respondents would prescribe adjuvant chemotherapy to genomic high-intermediate risk[Oncotype DX recurrence score(RS)21-25]females aged≤50 years regardless of the clinical risk classification.

Ground level utility of Access, Watch, Reserve classification: Insights from a tertiary care center in North India

BACKGROUND The overuse and misuse of antimicrobials contribute significantly to antimicrobial resistance(AMR),which is a global public health concern.India has particularly high rates of AMR,posing a threat to effective treatment.The World Health Or-ganization(WHO)Access,Watch,Reserve(AWaRe)classification system was introduced to address this issue and guide appropriate antibiotic prescribing.However,there is a lack of studies examining the prescribing patterns of antimi-crobials using the AWaRe classification,especially in North India.Therefore,this study aimed to assess the prescribing patterns of antimicrobials using the WHO AWaRe classification in a tertiary care centre in North India.Ophthalmology,Obstetrics and Gynecology).Metronidazole and ceftriaxone were the most prescribed antibiotics.According to the AWaRe classification,57.61%of antibiotics fell under the Access category,38.27%in Watch,and 4.11%in Reserve.Most Access antibiotics were prescribed within the Medicine department,and the same department also exhibited a higher frequency of Watch antibiotics prescriptions.The questionnaire survey showed that only a third of participants were aware of the AWaRe classification,and there was a lack of knowledge regarding AMR and the potential impact of AWaRe usage.RESULTS The research was carried out in accordance with the methodology presented in Figure 1.A total of n=123 patients were enrolled in this study,with each of them receiving antibiotic prescriptions.The majority of these prescriptions were issued to inpatients(75.4%),and both the Medicine and Surgical departments were equally represented,accounting for 49.6%and 50.4%,respectively.Among the healthcare providers responsible for prescribing antibiotics,72%were Junior Residents,18.7%were Senior Residents,and 9.3%were Consultants.These findings have been summarized in Table 1.The prescriptions included 27 different antibiotics,with metronidazole being the most prescribed(19%)followed by ceftriaxone(17%).The mean number of antibiotics used per patient was 1.84±0.83.The mean duration of antibiotics prescribed was 6.63±3.83 days.The maximum number of antibiotics prescribed per patient was five.According to the AWaRe classification,57.61%of antibiotics fell under the Access,38.27%in Watch,and 4.11%in Reserve categories,suggesting appropriate antibiotic selection according to these criteria.The distribution of antibiotics prescribed according to the WHO AWaRe categories is presented in Figure 2.The difference in prescribing frequencies amongst departments can be noted.Most of the antibiotics prescribed in the Access category were from the Medicine department(75.4%),followed by Surgery(24.6%).For Watch antibiotics,Medicine had a higher proportion(63.4%)compared to Surgery(36.6%).In terms of seniority,Junior Residents prescribed the highest number of antibiotics for both Access and Watch categories in Medicine and Surgery departments.Senior residents and Consultants prescribed a lower number of antibiotics in all categories and departments.Only a few antibiotics were prescribed in the Reserve category,with most prescriptions being from the Medicine department.The study also evaluated the Knowledge and Awareness of Healthcare professionals towards the WHO AWaRe classi-fication through a questionnaire survey.A total of 93 participants responded to the survey.Among them,most parti-cipants were Junior Residents(69.9%),followed by Senior Residents(25.8%)and Faculty(4.3%).When enquired if they knew about the WHO AWaRe classification only 33.3%of the participants responded positively.Of those who were aware of the AWaRe classification,the most common source of information was the internet(31.2%),followed by the antimicrobial policy of their institution(15.1%)as seen in Table 2.The survey results on the knowledge and awareness of AMR among healthcare professionals are also presented in Tables 3 and 4.Out of the 93 participants,68(73.1%)agreed that the emergence of AMR is inevitable,while only 13(14.0%)disagreed that AWaRe usage will result in the inability to treat serious infections.Additionally,58(62.4%)agreed that it will lead to lengthier hospital stays,43(46.2%)agreed that the success of chemotherapy and major surgery will be hampered,and the majority also agreed that its use will lead to increased cost of treatment and increased mortality rates.Regarding the utilization of AWaRe in the hospital summarized in Tables 4 and 5,35.5%of the participants agreed that it should be used,while only 2.2%disagreed.Additionally,34.4%agreed that AWaRe reduces adverse effects of inappro-priate prescription.However,37.6%of the participants considered that AWaRe threatens a clinician's autonomy and 30.1%thought that its use can delay treatment.Additionally,the DDD of each drug was also evaluated.The usage of various antimicrobial drugs in a hospital setting,along with their daily doses and DDD according to the WHO's Anatomical Therapeutic Chemical classification system was calculated.Some of the important findings include high usage rates of ceftriaxone and metronidazole,and relatively low usage rates of drugs like colistin and clindamycin.Additionally,some drugs had wider ranges than others.Comparison of WHO defined DDD with Daily Drug dose(Mean)in the studied prescriptions is represented in the Clustered Bar chart in Figure 3.Finally,the Mean Daily Drug Dose for prescribed drugs was compared with WHO defined DDD for each drug using a Student’s T test.The mean daily drug dose of amoxy/clav was significantly higher than the WHO DDD(1.8 vs 1.50,P=0.014),while the mean daily drug dose of metronidazole and doxycycline were significantly lower than the WHO DDD(P<0.001 and P=0.008,respectively).The mean daily drug dose of piperacillin/tazobactam,amikacin,clindamycin,and levofloxacin did not show significant differences compared to the WHO DDD(P>0.05).CONCLUSION This research indicates an appropriate proportion of prescriptions falling under the Access category(57.61%),suggesting appropriate antibiotic selection,a significant proportion also belongs to the Watch category(38.27%),emphasizing the need for greater caution to prevent the escalation of AMR.There is a moderate level of awareness among healthcare professionals about AMR and the steps being taken to tackle it,highlighting the gap in implementation of policies and need for more steps to be taken in spreading the knowledge about the subject.However,there is a significant difference between the WHO DDD and the prescribed daily dose in the analysed prescriptions suggesting overuse and underuse of antibiotics.

COVID-19 Downgraded Already Impaired Mental Health of Medical Undergraduates during the Pandemic Years

Background: Measures to contain the COVID-19 transmission reached teaching routines of universities worldwide with possible mental health consequences for anxiety. This study assessed prevalence and risk factors for stress, depression, and anxiety (SDA) in medical students during quarantine by COVID-19. Methods: A cross-sectional observational study of medical students by means of the DASS-21 questionnaire. Risk factors for SDA were assessed based on epidemiologic questions related to COVID-19. Receiver Operating Characteristics (ROC) curves were calculated for each predictor, as well as sensitivity and specificity. Results: This survey reached 1009 responses. A prevalence of 77.5% for some SDA disorder was found, 63% being severe. Previous diagnosis of psychiatric disorder was a factor of risk for anxiety (OR 2.78 CI95% 1.44 - 14.25, p = 0.044), as well as for depression (OR 3.37 CI95% 1.98 - 6.02, p Conclusion: Psychiatric conditions as well as chronic illnesses were risk factors for high prevalence of anxiety, depression and stress during the COVID-19 pandemic among medical students.

Multi-center investigation of breast reconstruction after mastectomy from Chinese Society of Breast Surgery:A survey based on 31 tertiary hospitals(CSBrS-004)

Objective:Multi-center data on the current status and trends of breast reconstruction after mastectomy in China are lacking.Herein,we conducted a cross-sectional survey to investigate the current clinical practice pattern of postmastectomy breast reconstruction among Chinese female patients with breast cancer.Methods:A standardized questionnaire used to collect information on breast reconstruction among females diagnosed with breast cancer was distributed by 31 members of the Chinese Society of Breast Surgery between January 1,2018 and December 31,2018.Information was collected on tumor characteristics,treatment,mesh application,nipple-areola complex(NAC)preservation,postoperative complications,bilateral reconstruction,patient satisfaction and local recurrence.The overall rate of breast reconstruction was assessed,and the characteristics were compared across patient groups with different reconstruction approaches.Results:A total of 1,554 patients underwent breast reconstruction after total mastectomy,with a reconstruction rate of 9.6%.Among them,1,190 were implant-based,and 262 underwent autologous reconstructions,while 102 cases underwent a combination of both.Patients who underwent implant-based reconstruction were younger than those who received autologous reconstruction(40.1±4.6 vs.45.0±5.9,P=0.004).Compared to patients with autologous reconstruction,mesh application(25.5%vs.6.5%),NAC preservation(51.8%vs.40.5%)and reconstruction failure(1.8%vs.0)were more frequently reported among those with implant-based reconstruction.There was no significant difference in general satisfaction across three reconstruction approaches,though patients with autologous reconstruction reported the highest aesthetic satisfaction among the three groups(P=0.044).Conclusions:Implant-based breast reconstruction remains the dominant choice among patients,while autologous reconstruction was associated with higher aesthetic satisfaction.Our multi-center investigation based on the findings of the tertiary hospitals of Chinese Society of Breast Surgery may guide a future series of clinical studies on breast reconstruction in China.

Abusive supervision and turnover intention: Mediating effects of psychological empowerment of nurses

Objective: This study aims to determine the mediating effects of psychological empowerment on abusive supervision and turnover intention as perceived by nurses to provide information to change the status of nurse turnover.Methods: A cross-sectional survey (a questionnaire examining perceptions of abusive supervision,measurement of psychological empowerment,and questionnaire for turnover intention) was used to collect data.A total of 1127 clinical nurses,who were recruited through convenience sampling,participated in the survey.Results: Nurses' average perceived abusive supervision,psychological empowerment,and turnover intention scores were 1.62 ± 0.95,3.24 ± 0.83,and 14.17 ± 3.78,respectively.Psychological empowerment was found to mediate the relationship between abusive supervision and turnover intention (P< 0.01).Turnover intention tends to be stronger and psychological empowerment reduced when nurse managers adopt an abusive leadership style.Conclusions: Nurses' psychological empowerment is an intermediary variable that predicts the relationship between abusive supervision and turnover intention.Nurse managers should manage abusive supervision to increase nurses' psychological empowerment and decrease turnover intention.

HIV/AIDS related perception and behavior: A comparative study among college students of different majors in China

Objective:In order to carry out proper education and intervention of AIDS based on different features and demands of different majors,this study aimed to compare the difference of college students from six majors in China in the aspects of AIDS-related knowledge,attitudes and behaviors.Methods:A questionnaire survey was carried out among 18,644 students in 30 colleges/universities from 9 provinces of China,who were recruited through stratified cluster sampling.AIDS-related knowledge,attitude,condom-use intention,self-efficacy and sexual behavior of these students were investigated.Results:AIDS-related knowledge level of students majoring in education was the lowest while that of medical students was the highest as well as highest self-efficacy of condom use.Students of music or fine arts had the strongest intention to use condoms,while the students majoring in education had the weakest.The sexually active percentages of male students from different majors ranked as follows:music or fine arts(29.5%),minority nationality(12.2%),science&tech(10.9%),medicine(10.6%),educationmajor(10.0%),and liberal arts(8.2%).Among female students,the rank was music or fine arts(11.0%),science&tech(6.2%),education-major school(4.5%),minority nationality(4.5%),liberal arts(4.1%),and medicine(2.8%).Conclusion:It is urgent to enhance proper AIDS-related education and intervention based on the features and demands of students from different majors or universities,for example,to enhance comprehensive AIDS prevention education among students major in education and to increase behavioral skills to prevent sexually transmitted diseases among students from colleges or faculty of music or fine arts.

Predictors of happiness among Iranian nurses

Objectives:This study aimed to assess happiness and its predictors among a group of Iranian hospital nurses.Methods:This cross-sectional study was done in 2016 on 620 hospital nurses who worked in five teaching hospitals affiliated to Kashan University of Medical Sciences,Kashan,Iran.Nurses were recruited through the census method.Data collection instruments were a researcher-made demographic and occupational characteristics questionnaire,the Oxford Happiness Inventory,and the Minnesota Job Satisfaction Questionnaire.Data analysis was done through stepwise multiple linear regression analysis.Results:Among 620 recruited nurses,422 returned their questionnaires completely filled.The mean of their happiness was 123.4±18.4 in the possible score range of 29-174.The significant predictors of happiness were satisfaction with mental health,monthly salary,satisfaction with salary,quality of life,current hospital ward,the length of working in the current ward,work shift,age,job satisfaction,and satisfaction with physicians'conduct and performance.These variables explained 50.3%of the total variance of happiness.Satisfaction with mental health had the greatest proportion in explaining the variance of happiness.Conclusion:Nurses in teaching hospitals in Kashan,Iran,have moderate happiness.Their happiness is affected by different factors,particularly by satisfaction with their mental health.Health policy-makers and authorities,in developing workforce-related plans and programs,need to pay special attention to nurses'happiness and its contributing factors.

Investigation for the transcultural self-efficacy of nurses in Guizhou,China

Aim:As conflict caused by cultural diversity among patients in China continues to rise,hospitals are in urgent need for improvement of transcultural efficacy among nurses.This study aims to evaluate the transcultural self-efficacy of nurses working in the tertiary general hospital in Guizhou Province,an ethnic minority region in western China,and to identify whether nurses'demographic characteristics affect their transcultural self-efficacy.Method:We used the Chinese version of the Transcultural Self-Efficacy Tool(TSET-CV)to survey 1,190 inservice nurses.Results:Results showed that the level of transcultural self-efficacy of the nurses was generally moderate;few of the nurses had high or low transcultural self-efficacy.The nurses'transcultural self-efficacy was affected by demographic variables,including age,marital status,employment type,income,work experience,and whether or not they were head nurses.Having a stable work environment,a stable marriage,a good educational background,and a high-ranked professional title were associated with increased transcultural self-efficacy.Conclusion:Nursing administrators in hospitals should offer continuing education on transcuitural nursing according to nurses'demographic characteristics and the SEST scores.

Congenital hypothyroidism as a risk factor for hearing and parents’ knowledge about its impact on hearing

Aim:To evaluate the hearing of children with congenital hypothyroidism(CH)and to analyze the knowledge that parents’have on the possible auditory impacts of the disease.Methods:A total of 263 parents/guardians were interviewed about aspects of CH and hearing.Audiological evaluation was performed on 80 participants,divided into two groups:with CH(n?50)and without CH(n紏30).Clinical and laboratory CH data were obtained from medical records,pure tone auditory thresholds and acoustic reflexes were analyzed.The auditory data was compared between groups.Student’s t-test and Chi-square were used for statistical analysis at a significance level of 5%(p<0.05).Results:The majority(78%),of the parents were unaware that CH when not treated early is a potential risk to hearing.There was no correlation between socioeconomic class and level of information about CH and hearing(p>0,05;p=0.026).There was a statistically significant difference between the auditory tone thresholds of the groups and between the levels of intensity necessary for the triggering of the acoustic reflex.The group with CH presented the worst results(p<0.05)and absence of acoustic reflex in a normal tympanometric condition.Conclusions:Children with CH are more likely to develop damage to the auditory system involving retrocochlear structures when compared to healthy children,and that the disease may have been a risk factor for functional deficits without deteriorating hearing sensitivity.The possible impacts of CH on hearing,when not treated early,should be more publicized among the parents/guardians of this population.

Academic institutional repositories in China:A survey of CALIS member libraries

Purpose: China Academic Library & Information System(CALIS) planned to launch an institutional repository(IR) project to promote IR development and open access at colleges and universities in China. In order to get to know the current state of IRs in academic institutions, with the help of Peking University Library, CALIS Administrative Center conducted this survey.Design/methodology/approach: We conducted an online survey of CALIS member libraries.Findings: Firstly, the development of IRs at China's colleges and universities is still in its infancy. Secondly, the Chinese colleges and universities have reached a consensus on the objective for having an IR. Thirdly, they are having high expectations of IR functions. Fourthly,they prefer to establish a centralized IR system at a minimum cost. Finally, there are both similarities and differences between the Chinese academic institutions and their counterparts in other countries in the state of IR development.Research limitations: The questionnaire needs to be improved because there is a lack of enough questions for those who do not plan to build an IR. Comparatively lower rate of valid questionnaire return can affect the accuracy of the results. It is hard to go into an in-depth discussion only based on the data collected from this questionnaire survey, and consequently,the findings from the survey can hardly present an accurate and comprehensive picture of the current state of IR development in the academic sector in China.Practical implications: The survey results provide essential foundation for CALIS IR project,and meanwhile the research can serve as a reference source for the future studies of the development of IRs at China's colleges and universities.Originality/value: It is the first national survey focused on the development of IRs in academic institutions in China.

A survey study on motivations for citation:A case study on periodicals research and library and information science community in China

A large number of theoretical and empirical studies on citation behavior have been conducted internationally. Although some theoretical studies on such topic have been carried out in China, few studies have focused specifically on this area from an empirical perspective, resulting in the lack of literature on the findings of actual surveys. To address this challenge, we conducted two questionnaire surveys to understand the motivations of the researchers on citation. One survey covers the authors who published articles in Chinese Journal of Scientific and Technical Periodicals, while the other targets the most productive and most cited Chinese authors in library and information science. The results show that citation behavior is not only motivated by rational factors, but also by other social factors.

Recreational Attractiveness of Urban Parks and Implications for Their Management:A Case Study in Changchun,China

Urban parks are an important part of urban ecosystems and also provide recreational services for urban residents.However,it is still unclear how the recreational attractiveness of urban parks can be evaluated.In this study,12 typical parks in Changchun,China were selected for evaluation of their recreational attractiveness.We built a recreational attractiveness evaluation system based on the analytical hierarchy process(AHP)to produce a composite evaluation index.This method included:1)the landscape quality of the parks;2)the recreational facilities;3)the conditions of the area;and 4)the accessibility of the parks.Our results showed that Nanhu Park,Children’s Park,Shengli Park,and Jingyuetan Forest Park had high recreational attractiveness,whereas Linyuan Park had the lowest attractiveness among the 12 parks.These results agreed with the information obtained from a field survey of the actual recreational and revisit rates,which showed that the evaluation index is reliable.Correlation analysis showed that the landscape quality and recreational facilities of parks had a direct effect on their recreational attractiveness.A negative correlation was found between the accessibility of a park and its recreational attractiveness.We conclude that if the scenery and facilities are not as good as a visitor expects,then they may choose to visit a different park,even if it takes a longer time to reach.
