Authors: Yaseen Muhammad , Hasan Gul , Bakhsh Zuhra Lal
Published: June 2023

The study explored the understandings of young adults with congenital heart disease (CHD) having age range between 18-22 years and this study also investigated the coping behaviors. The Interpretative Phenomenological Analysis (IPA) was utilized in order to provide a detailed perception towards the experiences of the patients. Semi-structured interview was conducted with a voluntary sample of six participants who were diagnosed as CHD. The study highlighted Four main themes, such as loss of person identity and social distinctiveness, concerns about physical and future, negative emotions/thoughts, and adaptive and maladaptive coping behavior. Females experienced greater feeling of loss as compare to male, and were more concerned about the future occurrence of the disease, and they also stated severe adverse thoughts and emotions. Females sensed stress, and death anxiety; and the male was hopeful for the recovery. Adaptive coping style was applied by all the patients whether male or females. Afterward the recognition that preliminary managing styles were effective then they become optimistic and demanded for the family and peer support, they also applied social avoidance because they thought are incapable of social functioning. The research conducted in America or other western countries are found similar in result. Because they also applied care, support and treatment. Health care workers and therapists must realize the adverse psychosocial effects of young adults living with a heart disease and offer proper psychological and social support. Developments in care have upgraded the endurance and value of life for the young adults with CHD.

Published: June 2023

При получении углеродных наноматериалов в основном используют наночастицы металлов, реже их оксидов. Наночастицы оксида никеля были исследованы с помощью рентгеноструктурного анализа и обнаружено, что они имеют стандартную кубическую кристаллическую структуру. По формуле Дебая-Шеррера оценен размер частиц, который составляет ~12 нм. ИК-Фурье-спектроскопия показывает колебания в диапазоне 483−719 см−1. Результаты спектроскопии комбинационного рассеяния света показывают, что пик оксида никеля лежит на частоте 509 см−1, а это указывает на возможность использовать наночастицы оксида никеля в качестве катализатора при выращивании углеродных нанотрубок.

Este artículo describe diferentes conductas que podrían aumentar y mejorar el aprendizaje motriz enfatizando la práctica específica del tenis.
Aplicación de la Práctica Variable al Entrenamiento de la Técnica en el Tenis
Authors: Sanz David , Moreno Hernández Francisco Javier
Published: June 2023

El ser humano es interpretado como un sistema complejo con capacidad de adaptación y en continua interacción con su entorno (Kelso, 1995). Cualquier variación que se produzca a su alrededor provocará cambios en el sistema ajustándose a las condiciones que le rodean. Esta capacidad de adaptación, característica de los sistemas biológicos, resulta un adecuado marco de referencia para entender los procesos de aprendizaje motor (Davids, Button y Bennett, 2008). Lo que entendemos por aprendizaje partiría de un proceso de adaptación a las tareas propuestas al aprendiz. Si las tareas propuestas se repiten o perduran en el tiempo, el sistema tiende a un nuevo estado de equilibrio adquiriendo nuevas propiedades en función de las características de las tareas. Es decir, los cambios que provoquemos en el comportamiento tomarán una u otra dirección en función de los condicionantes de las tareas (Moreno 2006). Es ahí donde la práctica variable interviene, persiguiendo que el tenista explore su paisaje perceptivo-motor, en busca de nuevos patrones de coordinación o atractores, permitiendo la emergencia de los patrones técnicos más adecuados para resolver las diferentes situaciones de juego.

The global issue of widespread and unsustainable consumption has resulted in significant problems such as pollution and global warming. As a result, there is an increasing demand for greater understanding and use of Eco friendly products. This study's main goal was to investigate how university student's knowledge of Eco friendly products affected their purchasing decisions. The precise goals were to ascertain whether awareness, price, availability, value, and quality had an effect on university student's decisions to buy environmentally friendly products and to investigate how awareness, price, availability, value, and quality predict their intention to buy such products. Data from 120-student online survey was analyzed using a structural equation modeling approach. The results show that university student's purchase decisions are most significantly positively impacted by the quality of Eco friendly products. However, it was discovered that the influence of Eco friendly product awareness on their decision to buy green products was comparatively small. The study also demonstrates that elements like price, awareness, and exceptional quality are mostly responsible for the influence of green product awareness on university students buying behavior. In contrast, the perceived value of the products does not appear to be a critical factor influencing the green purchase intentions of university students. The implications of the study, along with its limitations for future research, are discussed. Keywords: Eco-friendly Products, Consumer purchasing behavior, Youth, University Students, Pakistan.

Published: June 2023

The tapestry of world affairs in the post-Westphalian era has introduced various multifaceted concepts for the protection and preservation of the territorial integrity of states around the world. Unlike in the medieval ages when the rule of ‘might is right’ was prevalent, the concept of territorial integrity has provided an impeccable locus standi to all the big and small legitimate countries. The protection of the inviolability of their territorial jurisdiction is guaranteed under the auspices of an effective international legal framework. In the following lines, various aspects of the “principle of territorial integrity” have been critically evaluated in considerable detail. The facets about evolution, interpretations, differences with other resembling concepts under the principles and theories of international law have been construed herein below. Moreover, the use of the “principle of territorial integrity” for the resolution of past disputes has also been mentioned at great length. The prospects and recommendations for using this principle for settlement of present international territorial disputes for the collective peace and serenity of the world have also been elaborated in the final part.

A variety of graphical invariants have been described and tested, offering lots of applications in the fields of Nano chemistry, computational networks and different scientific research areas. One commonly studied group of invariants is the topological index, which allows the prediction of the chemical, biological and physical properties of a chemical structure. Topological indexes are numerical quantities that can be used to describe the properties of the molecular graph. In this article, we computed the face index formula for certain molecular structures of benzenoid series such as polycyclic aromatic hydrocarbon (PAH), jagged-rectangle benzenoid system (JRB[m,n]) and the series of concealed non-kekulean benzenoid system.
Gender-based harassment in Swedish workplaces and alcohol-related morbidity and mortality: A prospective cohort study
Authors: Blindow Katrina J , Thern Emelie , Hernando-Rodriguez Julio C , Nyberg Anna , Magnusson Hanson Linda L
Published: June 2023

OBJECTIVE: The study investigated experiences of different types of work-related gender-based harassment (GBH), specifically sexual and gender harassment, as risk factors for alcohol-related morbidity and mortality (ARMM).

METHODS: Information about experiences of (i) sexual harassment (SH-I) and (ii) gender harassment (GH-I) from inside the organization and (iii) sexual harassment from a person external to the organization (SH-E) were obtained from the Swedish Work Environment Survey 1995–2013, a biannual cross-sectional survey, administered to a representative sample of the Swedish working population. The survey responses from 86 033 individuals were connected to multiple registers containing information about alcohol-related diagnoses, treatment, or cause of death. Cox proportional hazard models were fitted to assess hazard ratios (HR) of incident ARMM during a mean follow-up of eight (SH-I and GH-I) and ten (SH-E) years.

RESULTS: A higher prospective risk estimate of ARMM was found among participants who reported experiences of SH-E [HR 2.01, 95% confidence interval (CI) 1.61–2.52], GH-I (HR 1.33, CI 1.03–1.70), or SH-I (HR 2.37, CI 1.42–3.00). Additional analyses, distinguishing one-time from reoccurring harassment experiences, indicated a dose–response relationship for all three harassment types. Gender did not modify the associations. Under the assumption of causality, 9.3% (95% CI 5.4–13.1) of the risk of ARMM among Swedish women and 2.1% (95% CI 0.6–3.6) among Swedish men would be attributable to any of the three types of GBH included in this study.

CONCLUSIONS: Experiences of GBH in the work context may be a highly relevant factor in the etiology of ARMM.

Objectives: An appropriate prostate specific antigen (PSA) cut-off value in Thailand has not been investigated, nor has an age-specific PSA reference range. This study aims to evaluate the correlation between metabolic syndrome, metabolic factors, and age specific PSA level. Materials and Methods: A cross-sectional study in men who underwent medical checkups from September 2019 to December 2019. The 95th percentile PSA value was applied to the normal age-specific reference range. Correlations between PSA levels and a variety of factors were determined using linear regression. Results: A total of 507 men met the criteria to be included in the analysis. Age-specific PSA reference ranges for men aged 40-49, 50-59, and 60-70 years were 0-2.3, 0-3.4, and 0-4.2 ng/ml, respectively. The multivariate adjusted geometric mean PSA model indicated that the factors related to PSA were age, higher body mass index (BMI) and serum fasting blood sugar (FBS) ≥ 100 mg/dl. The age group 50-59 and 60-70 have a 43% and 99% increase in mean PSA compared to the age group 40-49, respectively (p < 0.001). A higher BMI was associated with lower PSA (p < 0.001). And the serum FBS ≥ 100 mg/dl showed a 15% reduction in mean PSA compared to FBS < 100 mg/dl (p = 0.018). Conclusion: The age-specific PSA reference in Thai men was lower than reported in a previous study. Use of the lower PSA cut-off may increase the sensitivity of prostate cancer screening. This study demonstrates that age, BMI, and FBS may all influence the clinical interpretation of serum PSA levels. Screening for prostate cancer using PSA should be carried out with caution in those who have those risk factors.

Authors:   Division of Urology, Department of Surgery, Khon Kaen Hospital, Khon Kaen, Thailand, Somwung Theerayuth
Published: June 2023

Objective: To evaluate the clinical complications and functional outcomes associated with the modified Y-pouch neobladder technique, in particularly those related to the prevention of anastomosis stricture. Materials and Methods: Functional outcomes and associated complications were evaluated in 25 patients (23 men, 2 women) who underwent radical cystectomy with Y-pouch neobladder by isolating 50 cm of the ileum between October 2010 and December 2020. Clinical complications included anastomosis stricture formation, hydronephrosis, pyelonephritis, vesical stone formation, and renal deterioration. Results: No cases exhibited uretero-neobladder anastomosis stricture, urethro-neobladder anastomosis stricture, or vesical stones. In addition, no complications were observed in relation to metabolic acidosis. One year after surgery, daytime and nighttime continence rates among patients were 88% and 72%, respectively, with almost every case exhibiting near-normal voiding frequency. The average maximal neobladder capacity was 425.60±20.83 ml with a mean follow-up period of 2.8 years. There was a no statistically significant increase in creatinine with values of 1.45 mg/dl, 1.14 mg/dl, 1.21 mg/dl, and 1.35 ml/dl being recorded at preoperative baseline, 3, 6 and 12 months, respectively. Conclusions: The Y-pouch neobladder created by isolating 50 cm of the ileum showed a low incidence of uretero-neobladder anastomosis and urethra-anastomosis stricture rate. In addition it was a straightforward procedure with a quickly reconstructed reservoir, had good functional outcomes which were comparable to most popular orthotopic neobladders, had no significant increase in postoperative creatinine levels and improved quality of life for patients.

Objective: To identify factors that could predict pathologic response to neoadjuvant (NAC) therapy in muscle invasive bladder cancer (MIBC) patients and report the impact of NAC on the risk of perioperative complications after radical cystectomy at our institution. Materials and Methods: We reviewed the hospital database from January 2014 to March 2021 for MIBC patients who received NAC prior to radical cystectomy (RC). All patients were divided into a responder (pT ≤ T1) or non-responder group (> pT2). Data was analyzed to determine the factors associated with pathologic response to NAC. A subgroup analysis of the gemcitabine and carboplatin (GCb) regimens was also carried out. Results: Out of the 50 patients who met the inclusion criteria, 13 (26%) were categorized as responders and 37 (74%) as non-responders. With regard to NAC variables, 12 patients (24%) received cisplatin-based NAC, and 38 patients (74%) received GCb. From the multivariate analysis, pretreatment hemoglobin (Hb) > 12 g/dl (OR 16.42, 95% CI 1.78-151.86, p = 0.01) and neutrophil-to-lymphocyte ratio (NLR) < 3 (OR 12.81, 95% CI 1.36-120.9, p = 0.03) were associated with significantly increased odds of pathologic response, while tumor size < 4 cm (OR 12, 95% CI 1.92-75.05, p = 0.008) was associated with significantly increased odds of pathologic response in the subgroup analysis. Conclusions: Pretreatment Hb and NLR were independently associated with pathologic response to NAC. For MIBC patients who are cisplatin ineligible, GCb followed by RC may be the recommended treatment, particularly in those with tumors less than 4 cm in size. In addition, administering NAC prior to RC does not increase the risk of perioperative complications.

Objective: Androgen deprivation therapy (ADT) is often the treatment of choice in metastatic prostate cancer patients. However, there is currently an insufficiency of biomarker-related data that can be used in order to predict how the disease would respond to ADT. In this study we evaluated the clinical response to ADT, including factors which are affecting the progression of the disease into castration-resistant prostate cancer (CRPC) in patients with de novo metastatic prostate cancer. Materials and Methods: This retrospective study incorporated patients with metastatic prostate cancer who received ADT at our center from January 2008 to December 2019. Baseline characteristics, mode of ADT, prostate-specific antigen (PSA), blood chemistry, Gleason score (GS) grade group, location, and the number of metastases were analyzed. The risk factors affecting the progression of the disease were identified. Results: Data from 125 patients were included in the study. One hundred patients (80%) were classified as suffering from high volume metastatic prostate cancer and six patients (6%) with visceral metastasis. Baseline PSA in high volume and low volume metastatic prostate cancer were defined as 500 ng/ml and 215.1 ng/ ml respectively. Eighty-one patients (64.8%) received a gonadotrophin-releasing hormone (GnRH) agonist while 42 patients (33.6%) underwent bilateral orchi- ectomy. Time to CRPC in high and low volume metastasis was 12 months and 23 months respectively. Patients with Alkaline Phosphatase (ALP) ≥350 U/L had 8.5 months to CRPC while patients with ALP <350 U/L had 15 months. High GS grade group (3-5), short time to PSA nadir (<6 months), PSA nadir level (≥ 2 ng/ ml), and serum ALP ≥350 U/L were independent factors associated with shorter time to CRPC. Conclusion: The clinical management of metastatic prostate cancer is challenging; the main aims of treatment are to prolong overall survival whilst maintaining quality of life. Patients with aggressive tumors, high volume metastasis, short time to nadir (TTN), high PSA nadir level, and high ALP level were independent factors associated with shorter time to CRPC.

Published: June 2023

Frequency-volume chart (FVC) and Bladder diary (BD) are widely accepted as an additional tool to evaluate lower urinary tract symptoms. They are simple and inexpensive as well as provide more precise information. However, the guidelines and experts recommend 3-day FVC/BD for evaluation both men and women with lower urinary tract symptoms, it may not be enough for some specific symptoms. To avoid poor compliance and poor reliability, the appropriate duration and instruction are mandatory in each patient. Moreover, there are some limitation and concerns need to be recognized before interpretation. This review would like to demonstrate the appropriate duration of FVC/BD to increase completion rate, compliance and reliability as well as to decrease interpretation errors of FVC/BD.

Objective: Postoperative wpain after ureteroscopic removal of ureter and kidney stones frequently leads to re-hospitalization, revisit and increased cost. However, risk factors and incidence for early postoperative pain are still unclear. The aim of this study is to investigate the associated risk factors and the incidence of acute postoperative pain after ureteroscopic stone removal in the ureter and kidney. Materials and Methods: Retrospective data from 306 consecutive patients who underwent ureteroscopic treatment for ureteral and kidney stones from January 2016 to December 2020 were collected. The patients were divided into two groups: (i) Mild postoperative pain (n = 179), defined as a pain score lower than four on the visual analog pain scale during the first operative day, and (ii) Moderate to severe postoperative pain (n = 127) was defined as a pain score of greater than or equal to 4 during the first operative day. Potential risk factors were included in the univariable and multivariable regression analyses to identify risk factors for developing moderate to severe pain. Results: 127 (41.5%) patients experienced moderate to severe postoperative pain on the first postoperative day. From multivariable analysis, positive pre-operative urine culture, operative time of more than 60 minutes, a stone procedure in the ureter, a postoperative stent, and ureter injury greater than grade I were related to moderate to severe pain with significance risk ratios (RR) of 2.99, 3.70, 4.87, 3.30, and 2.96, respectively (p < 0.05). Conclusion: Pain is a frequent postoperative problem associated with ureterscopic removal of stones and should be pro-actively treated with care. Patients are at a higher risk of moderate to severe pain if they required the ureteral procedure, had prolonged operative time, ureter injury after the procedure, needed a stent postoperatively, or had a history of positive preoperative urine culture.

Objective: Systematic transrectal ultrasound (TRUS) guided biopsy has been considered a gold standard for prostate cancer diagnosis for many decades. The problem of this conventional method is the low detection rate especially in the case of repeat biopsy. This results from a limitation associated with ultrasound imaging inhibiting the visualization of cancerous lesions during the procedure. More recently, there has been increasing importance attributed to the use of multiparametric MRI for the identification of cancer inside the prostate gland. Targeted prostate biopsy, using multiparametric MRI/ultrasound (mpMRI/US) fusion-guided technology helps improve the detection of prostate cancer and has become a novel standard for tissue diagnosis. This study was conducted to investigate and report on the cancer detection rate of mpMRI/US fusion guided prostate biopsies at Siriraj Hospital. Materials and Methods: Data pertinent to patients who underwent mpMRI/US fusion guided biopsy at Siriraj Hospital between September 2017 and December 2019 was retrospectively reviewed. Results: A total of 499 men underwent mpMRI/US fusion guided biopsy, with the transperineal approach being used in the vast majority of cases (91.8%). Targeted biopsy provides a better cancer detection rate than systematic biopsy (55.3% vs 47.1%, p = 0.009). Combined targeted and systematic biopsies improved cancer detection rate compared to systematic biopsy alone (60.3% vs 47.1%, p < 0.001). A subgroup analysis of men with positive biopsies showed that detection of clinically significant cancer (Gleason grade group ≥ 2) was no different between targeted and random biopsies (87.2% vs 80.8%, p = 0.11). The common complications from transperineal approach were urinary retention (5.4%) and hematuria (5.2%) while complications of infection were rare (0.2%). Conclusion: We found that targeted biopsy with mpMRI/US fusion guided technology provides a more effective option for prostate cancer diagnosis. A combination of targeted and systematic biopsy improve prostate cancer detection rate more effectively than systematic biopsy alone. The transperineal approach is a safe and effective technique with a rare incidence of infectious complications.

Authors: DEMİRKAYA Seher
Published: June 2023

Sosyal güvenlik hakkı anayasal güvence altında bulunan temel haklardan biridir. Sosyal güvenlik, çalışma yaşamında kişilerin çalışmadıkları veya çalışamadıkları dönemlerin güvence altına alınması için kamu gücüyle ve genellikle zorunluluk esasına dayanan bir güvence yöntemidir. İspanya sosyal güvenlik sistemi 1880’li yıllara dayanan yapısı ile, vatandaşlarına ve ülkesinde ikamet eden yabancılara belli koşulların sağlanması ile söz konusu kamu sosyal güvenlik hizmetini sunmaktadır. İspanya sosyal güvenlik sisteminde sigortalılara ve hak sahiplerine iş kazası ve meslek hastalığı, analık, hastalık, malullük, ölüm, işsizlik, aile yardımları sigortaları kapsamında çeşitli yardımlar sunulmaktadır. Sosyal güvenlik yapısı genel rejim, serbest meslek çalışanlarına özgü rejim ve diğer özel rejimlerden oluşmaktadır. Serbest meslek çalışanlarına yönelik rejimde, 1 Ocak 2023 tarihinden itibaren geçerli olmak üzere birtakım değişiklikler yapılmıştır. Değişikliklerle birlikte genel rejime tabi olanlar ile serbest meslek rejimine ilişkin uygulamaların birbirine yakınlaştırılması hedeflenmiştir.
DEMOKRASİ VE DEMOKRASİNİN ÖLÇÜLMESİ: TÜRKİYE EKSENLİ BİR ANALİZ
Authors: KORKMAZ Tuğrul
Published: June 2023

Soğuk Savaş’ın bitimiyle birlikte tartışmasız egemenliğini ve zaferini ilan eden demokrasinin, tarihin her döneminde kabul gören ve ideal yönetim biçimi ya da rejim olmadığı bilinmektedir. Öyle ki geçmişte kötü yönetim biçimleri arasında sayılan demokrasinin yeniden gündeme gelmesi, ancak 18. ve 19. yüzyıllarda mümkün olmuştur. Demokrasinin bu dönemden sonra da doğrusal bir yükseliş trendinde olmadığı, yapılan çalışmalarda kendini göstermektedir. Zaman zaman gerilemeleri de içinde barındıran bu süreç, siyaset bilimcilerin temel tartışma konularından birini oluşturmaktadır. Demokrasinin, 21. yüzyılın başında ideal konumuna eriştikten sonra, bir gerileme sürecinin içine girdiği bu çalışmada elde edilen önemli bir sonuçtur. Dünyadaki gelişmelerden bağımsız olmayan Türkiye'nin de maalesef bu süreçten olumsuz etkilendiği bir gerçektir. Ampirik demokrasinin nitelikleri üzerinden yapılan değerlendirmeler, bu olumsuz etkilerin objektif gözlemini mümkün kılmaktadır. Çalışmada, Freedom House tarafından yayımlanan “Freedom in the World” raporları çerçevesinde, Türkiye’nin son on yılı incelenmiş ve analiz edilmeye çalışılmıştır. Bu analizler neticesinde Türkiye’nin belki de en çalkantılı 10 yıllık dönemi, demokrasi bağlamında ele alınarak, Türk demokrasisinin kalitesi ve niteliğini artırabilecek öneriler ortaya koyulmuştur.

Published: June 2023

The objective of the current research is to provide a systematic account of the variety of endemic plant species found in Pakistan, with a focus on family, distribution, and life form status. The existing research effort, which is based on a survey of the literature, field observations, and herbarium records, has identified 306 endemic plant species among 50 genera and 40 families. In accordance with an analysis of the life form or status of these plant species, herbs are dominant (n= 243 species, 80 %), while shrubs (n= 33 species, 11 %), under shrubs (n= 13 species, 4 %), trees (n= 10 species, 4 %), and grasses (n= 7 species, 2 %). The study revealed that Asteraceae is the most dominant family (n= 38 species), while Taraxacum is a dominant genus (n= 23 species). Distribution analysis revealed that the majority of species are distributed in mountainous areas of Pakistan. Khyber Pakhtunkhwa province is rich in endemism (n= 142 species, 37 %). The current study sheds light on Pakistan’s endemism situation. Further research that takes into consideration population levels and new risks is also required. The study will help policymakers in developing conservation strategies.

We give a counterexample in this amendment to show that there is an error in consideration of the statement "{\it if $f : X \to Y$ and ${\bf J}$ is an ideal on $Y$, then $f^{-1}({\bf J}) = \{f^{-1}(J) : J \in {\bf J}\}$ is an ideal on $X$}" by Hamlett in his paper "Lindelöf with respect to an ideal" [New Zealand J. Math. 42, 115-120, 2012]. We also modify it here in a new way and henceforth put forward correctly all the results that were based on the said statement derived therein.

Published: June 2023

The extensive existence of plastic in the environment has a serious effect on the living organism. In this study, the synthesis will be done in small quantity within the lab. Long lifetime, good barrier property, stiffness, tensile strength and tear strength make petro-chemical plastics more popular in society. Inspite of many advantages the plastic is proved to be more threatening for the mankind survival. The expected outcome of this project will be the biodegradable plastic which will be a great relief for society. Life begins from birth in which the play toy of newborn baby is plastic then as they grow up everything surrounding them is plastic, the plastic glass, plastic bottles, plastic buckets, plastic box etc. The research work on production of bio plastic using different plant parts will act as substitute for the plastic substances. For the betterment of living creatures and also for the betterment of the environment bioplastics formed from plant parts are better as compared to that of the plastics formed by traditional method. Due to the non-biodegradability of the plastics, they will be ominous for the whole system as the whole system depends on the plastic. Plastic pollution is responsible for the worsening of the habitat of organisms and the human lifestyle. With the help of this study, we will also analyze the properties such as water absorption capacity and bio-degradability. Mass production of bioplastic will be a great solution for plastic pollution.

A Three-dimensional Model of Digital Transformation for Small and Medium-sized Enterprises
Authors: Liu Kui
Published: June 2023

Small and medium-sized enterprises (SMEs) are important pillars of the national economy and play an irreplaceable role in increasing employment, improving competitive intensity, and increasing overall economic vitality. Digital transformation is an inevitable path for enterprises to enhance productivity to create economic and social value and achieve high-quality development. At present, digital transformation for multinational groups and large enterprises is a hot research topic, but the research results of scholars on digital transformation for SMEs are few and scattered. Due to the inherent limitations of SMEs, digital transformation is difficult, the transformation ratio is small, so finding a path and method that can effectively guide the digital transformation of SMEs has become an urgent problem. Based on the existing literature, this paper proposes a three-dimensional model for digital transformation of SMEs, which unites the strengths of enterprises, government and the flat ecological platform, overcoming the obstacles of inappropriate enterprise cognition, weak technical foundation of transformation, lack of transformation talents, unclear transformation direction and lack of funds in digital transformation, and greatly reducing the transformation resistance of SMEs. It makes a certain contribution to guiding the digital transformation and enriching the digital transformation methods and paths of SMEs.
