Introduction

Diabetes mellitus is one of the most common and serious chronic diseases in the United States. About 16 million Americans have diabetes, 5.4 million of whom do not know they have the disease. Diabetes is the leading cause of adult blindness, end-stage renal disease, and non-traumatic lower-extremity amputations (as a result of nerve disease). People with diabetes are 2-4 times more likely to have coronary heart disease and stroke than people without diabetes. In addition, poorly controlled diabetes can complicate pregnancy birth defects are more common in babies born to women with diabetes. Diabetes is a metabolic disease in which the body does not produce or properly use insulin, a hormone that is needed to convert sugar, starches, and other food into energy needed for daily life. There are three main types of diabetes, all of which are characterized by high levels of blood glucose (sugar).

Scientometrics study

Scientometric is one of the truly interdisciplinary research fields to extend almost all scientific fields. In addition, many extensive bibliometric studies of important science fields appeared during the last two decades. At present, the connotation of bibliometric turns out to be the science of measurement relating to documents. The word measurement means the application of mathematical and statistical techniques to find out the growth of documents, scattering, or literature in various types of documents, publication of documents by an author, impact of document, and so on. Cole and Eales (1917)2 in their publication on the history of comparative anatomy, applied statistical methods for analyzing the literature are called it statistical analysis. The most important contribution was made by Hulme (1923)3 when he published the book statistical bibliography, this term continued to be used for statistical measures till the end of the 1960s. Ranganathan (1948)4 coined the term librametry to denote measurement of various library activities and services using mathematical and statistical techniques. Alan Prichard (1969)5 coined the term bibliometric to denote the application of mathematical and statistical methods to books and other media, the process of written communication, and of the nature and course of a discipline. Van Raan (1997)6 According to scientometric research is devoted to Quantitative studies of science and technology. So this paper aims to analyze the contribution of many Scientometrics studies that have appeared in the literature to focus on the performance of science in the field of diabetic’s research in India.

Literature Review

Rajendran et al. (2013)7 examine the Indian research publications in wireless communication research during 2001-2012 from the SCOPUS database with 1128 publications. The study analysis the Scientometrics tools such as, the relative growth rate is 0.56 in the year 2002 and 0.26 in the year 2012. At the same time, doubling time is found that 1.24 in the year 2002 and 2.67 in the year 2012. An average degree of collaboration is 0.95, the CAI increased for double authors from 74 in the first block years to 103 in the second block years. On the other hand, it is decreased from the first block years to the second block years for single and multi-authors.

Vivekanandhan et al. (2016)8 analyzed the pollution control research output from the SCOPUS database during the period of 1985-2014. They analyzed scientometric tools such as authorship pattern, Citation index, Collaborative coefficient, modified collaborative coefficient, and block year-wise publications. The maximum number of 13692 (25.43%) publications is contributed in the 6th block of 2010-2014 and block year wise average degree of collaboration was 0.72. The maximum number of articles was contributed in the journal of water science and technology with a count of 1533 (11.61%) publications, the study, the United States provides a maximum number of 14689 (27.28%) research publications.

Batcha & Ahmad, (2017)9 analyzed the publications trend in the India journal and Pakistan journal: A comparative analysis using the scientometrics approach. The Pakistan Journal of library and information science is concerned with the maximum number of papers published in 2016 and the minimum in 2011. The highest number of research papers was contributed by multiple authors during the study period. The degree of collaboration was 0.69. It is found that the average value for CAI was around 100 during the study period and it reflects the world average. The author productivity is 0.50 and the average number of authors per paper is 1.98. The average number of pages per paper is 10.05. The average keywords per paper are 4.45. The majority of the contributions are by Pakistani authors (77.05%). The papers by Pakistani authors with foreign collaboration are minimal (4.10% of articles).

Batcha, Jahina, & Ahmad, (2018)10 analyzed the publications trend in DESIDOC Journal of Library and information technology during 2013-2017: Ascientometric approach. The DESIDOC Journal of Library and information technology was in the year 2014 and the total number of articles at the highest was accounted for 63. The extent of research contribution by the authors is explained under the authorship pattern and it was found that out of 227 articles, the average degree of collaboration at 0.69. The total average number of authors per paper found in the study was 9.65 and the average productivity per author was 2.59. The exponential growth rate was found to be 4.85 and also CAGR calculated was 9.1% which shows a developmental sign of activity. The period has witnessed a mean relative growth rate of 0.61. The mean doubling time for publications for the periods of 2013-2017 was 1.78.

Ahmad, Batcha, & Jahina, (2019)11 quantitatively measured the research productivity in the area of artificial intelligence at the global level over the study period of ten years (2008-2017). The study acknowledged the trends and features of growth and collaboration pattern of artificial intelligence research output. The average growth rate of artificial intelligence per year increases at the rate of 0.862. The multi-authorship pattern in the study is found high and the average number of authors per paper is 3.31. Collaborative Index is noted to be the highest range in the year 2014 with 3.50. The mean CI during the period of study is 3.24. This is also supported by the mean degree of collaboration at the percentage of 0.83. The mean CC observed is 0.4635.

Ravichandran and Vivekanandhan (2021)12 have examined the wireless network research Output in India from Scopus Database during 2010-2019: A Scientometric Analysis.

Table 2: Relative Growth Rate and Doubling Time

Relative growth rate of publications: The growth of publications was analyzed by using two parameter namely relative growth rate and doubling time by Mahapatra (1985)13. RGR is a measure to study the increases in number of articles in a particular period of time. It is calculated as

Equation

Where,

R (a)=RGR=the mean relative growth rate over the specific period of interval

W1=the logarithm of beginning number of publications/pages

W2=the logarithm of ending number of publications/pages after a specific period of interval

T2-T1=the unit difference between the beginning time and the ending time.

The doubling time is the time taken for the doubling of the number of records actually published within a stipulated period. The doubling time is calculated from the relative growth rate and the natural logarithm number is used, the difference has a value of 0.693. Thus the corresponding doubling time can be calculated by the following formula,

Equation

The relative growth rate (RGR) and the doubling time (DT) was calculated and the result are present in Table 3. From the study it is identified from the Table 3, the relative growth rate is 0.86 in the years 1976-1980 and 0.55 in the years 2016-2020. This study confirmed that relative growth rate is decreasing trend. At the same time doubling time found that 0.81 in the years 1976-1980 and 1.27 in the years 1916-2020 and it is conformed that doubling time is increasing trend.

Table 5: Block Year Wise Degree of Collaboration

Degree of collaboration is relationship between single author and multi author contributions. The degree of collaboration is calculated by the K. Subramanian (1983)14 formula and used for Ravichandran and Vivekanadhan (2021)15,

Equation

Where DC=Degree of Collaboration

Nm=Number of Multi author publications

Ns=Number of single author publications

In the present study

Nm=18933, Ns=823

So that the degree of collaboration=18933/(18933+823)=0.95

Table 6 shows that the degrees of collaboration in the field of diabetics research publications for Fifty year study period. From the study it is identified that, the degree of collaboration is between 0.74 in the years 1971-1975 and 0.97 in the years 2016-2020. The average degree of collaboration is 0.95. From this study it is identified that majority of diabetic research publications are contributed by collaborative authors in CAI=100 indicates that a countries coauthorships effort for a particular type of authorship is correspondents to the world average. CAI>100 reflects higher than the average co-authorship effort and CAI<100 shows that lower than average co-authorship effort for a given type of authorship pattern.

Table 12: Time Series Analysis

Table 12 shows that the time series analysis formula has been predicted for diabetics research publications for the year 2025 and 2030

Straight Line Equation is

Y=a+bx

Here,

ΣY=19758, ΣX2=285, ΣXY=154946

a=ΣY/N=19758/10=1975.8=1976

b=ΣXY/ΣX2=154946/285=543.6=544

Estimated publications in the year 2025 is when X=2025-1971=54

Y=a+bx

=1976+(544*54)=1976+29376=31352

Estimated literature in 2030 is when X=2030-1971=59

Y=a+bx

=1976+(544*59)=1976+32096=34072

The estimated growth based on a time series analysis statistical application will be expected in the diabetics research publications in the year 2025 is around are equal to 31352 and the year 2030 is around are equal to 34072. So that time serious analysis conformed that the publications on diabetic’s research is increasing trend.

Results and Discussion
