Introduction

Scientometrics is the study of measuring and analyzing science, technology and innovation. Major research issues embrace the dimension of impact, reference sets of articles to explore the impact of journals and institutes, considerate of scientific citations, mapping scientific fields and the formation of indicators for use in policy and organization contexts. In observe there is a important be related between scientometrics and other scientific fields such as bibliometrics, information science and science of science policy. Dengue diseases also known as break bone fever, is a mosquito-borne tropic a disease cause y the dengue virus.

Dengue diseases also known as break bone fever, is a mosquito-borne tropic a disease caused y the dengue virus. Symptoms consist of fever, headache, muscle and joint pains, and a quality skin rash that is similar to measles. In a small quantity of cases, the disease develops into the life-aggressive dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where stress occurs. Treatment of acute dengue is compassionate using either oral or intravenous rehydration for mild or moderate disease, and intravenous fluids and blood transfusion for extra severe cases. The number of cases of dengue fever has increased dramatically since the 1960s, with between 50 and 528 million people infected yearly. Early descriptions of the circumstance date from 1779, and its viral cause and transmission were understood by the early 20th century. Dengue has become a global problem since the Second World War and is endemic in more than 110 countries. Apart from eliminating the mosquitoes, work is ongoing on a vaccine, as well as medication targeted directly at the virus.

Signs and symptoms

Typically, people contaminated with dengue virus are an indicative (80%) or only have mild symptoms such as an unsophisticated fever. Therefore, travelers frequent from widespread areas are improbable to have dengue if fever or other symptoms start more than 14 days after arriving home. Children repeatedly experience symptoms related to those of the common cold and gastroenteritis (sickness and diarrhea) and have a greater risk of severe complications, though initial symptoms are generally unconcerned but contain high fever.

Review of Literature

Hang Wen and Yi Huang (2012) carried out a investigate on oxidative stress publications published among 1991 and 2010 in journals of all the focus categories of the Science citation index. Publication trends were analyzed by the retrieved consequences in periodical type and language, individuality of articles outputs, country, focus categories and journals, and the incidence of title-words and keywords used. Over the years, there was a significant growth in article outputs, with more countries participating and collaborating. The seven major industrialized countries (G7) published the majority of the world articles while the USA contributed about one-third of the total. Chinese and Indian outputs grew much faster than those of other countries in the past five years. Oxidative stress research in food and ecological associated fields increasingly became the conventional of the research. An analysis of the title-words, author keywords and keywords plus showed that antioxidants in human or rat cells were the hot topic in the field. In addition, "reaction oxygen species", "apoptosis", and "nitric-oxide" were major topics of oxidative stress research recently.

Gupta, R., & Tiwari, R. (2014) conducted a study based on quantitatively evaluate Indian dengue research output during the 10 years from 2003 to 2012, using Scopus international multidisciplinary database. The study focused on global publication output, share, rank, and citation impact of top 15 most productive nations, India's publications output, growth, global publication share and research impact, international collaborative papers share in national output and the share of major international collaborative partner countries in total India's international collaborative papers, contribution of various sub-fields and distribution by population age groups, productivity and citation impact of its leading Indian institutions and authors and Indian contribution in most productive journals. Among the top 15 most productive countries, India holds second position in dengue fever research output, with global publication share of 10.22% during 2003-12. The average citation per paper scored by India was 3.27, the least among the top 15 most productive countries during 2003-12. India's share of international collaborative papers was 10.55% during 2003-12, which increased from 9.12% during 2003-07 to 11.13% during 2008-12. Present India's research efforts in dengue research are low in view of the 50,222 cases of dengue in 2012 alone. The country needs to increase its research output and also increase its research impact substantially particularly through enhanced national and international collaboration, besides evolving a national policy for identification, monitoring and control of dengue cases and also evolving a research strategy with sufficient funding commitment to solve this growing national problem.

Sa'ed, H. Z. (2016) the focused emergence the of the dengue is a significant emerging and reemerging infection worldwide as a quickly growing and extensive public health problem, with diffusion occurring in more than 128 countries in Asia, Americas, southeast Africa, western Pacific, and eastern Mediterranean regions. The consistent search advance based on the exploit of the keyword "dengue" in the title, abstract and keyword field was used to get examine output related to dengue at a global level. All data related to dengue were collected from the past to December 31, 2015.A total of 19,581 dengue-related documents identified in the Scopus database. The leading countries in dengue research were the USA (4,709; 24.05 %), India (1,942; 9.92 %), Brazil (1,530; 7.81 %), Thailand (1,260; 6.43 %), the UK (1,129; 5.77 %), and France (1,087; 5.55 %). Only 226 (1.16 % of the overall global research effort in the dengue field) articles were published in the Arab region. The total number of citations for all publications was 352,710, with an average of 18.0 citations per publication. Furthermore, the h-index for all extracted data related to dengue research was 186. Kingdom of Saudi Arabia (KSA) was the most productive country in the Arab region with 102 documents representing 45.1 %. Furthermore, the h-index for all extracted data related to dengue research was 27. The USA was Arab's most main cooperative partner (46, 20.4 %), followed by India (36, 15.9 %). It was concluded that the amount of literature related to dengue research has considerably increased over the last decade. This bibliometric investigation has confirmed the significant role that the USA, India, Brazil, Thailand, the UK, and France participate in dengue research. The Arab world formed fewer publications correlated to dengue with lower eminence than further world countries.

Lalitha Kumari (2009) analyses the research output and impact in Synthetic Organic Chemistry (SOC) during 1998-2004, applying standardized scientometric indicators. Volume of research publications and their citations presented as percentage world share is illustrative of the trend pattern against time. Adopting relative indicator--Absolute Citation Impact (ACI) and Relative Citation Impact (RCI), a cross national assessment is attempted at three levels of aggregations global, Asian and Indian. Based on this investigation, it is concluded that G7 nations, being leaders in respect of the volume of literature published, and citations attracted are showing a decreasing trend over the years probably due to shifting and diversification of their research efforts to other emerging research fronts.

Bhardwaj, R. K. (2014) explored Dengue is a disease primarily characterized by headache, eye pain, skin rash, debilitating muscle, and sudden high fever. Presently, no vaccine is available to counter this disease. The best antidote is disturbance strategies to limit the extent of a virus. This paper is an attempt to make a scientometric assessment of research on dengue during 2001-12. The data of this study is obtained from Scopus (http://www.scopus.com) multidisciplinary database and analyzed from different angles. The study reveals that there were 9618 publications within the period under study. During the period 2001-12 annual growth rate was 13.4 percent, compared to 14.31 percent in the period 2001-2006, and 12.48 percent in 2007-2012. The USA is found to be the leading country on dengue research. The USA has contributed 24.88 percent of world publications. Mahidol University, Thailand, is the majority industrious organization which has contributed the highest number of publications (353 papers; 6502 citations; h-index value 40). Guzman, Maria Guadalupe from Instituto de Medicina Tropical Pedro Kouri, was found to be the most dynamic author in the field of dengue research.

Dutt, B., Kumar, S., & Garg, K. C. (2010) have analyzed of 2566 papers published during 1987 to 2008 and indexed by Science Citation Index--Expanded indicate a gradual rise in the quantum of output. About 80% of the papers appeared in journals originating from the USA. The UK, Netherlands, France, and Germany. Total output came from 74 countries of which 17 countries contributed 87% of the total output. The highest number of publications came from the USA followed by India. However, in the later block (1998-2008) the proportion of the output of both USA as well as India declined as compared to the first block (1987-1997). More than half of the scientific output is concentrated among four sub-disciplines of microbiology & virology, immunology & vaccine. Epidemiology and entomology. Among the prolific institutions, the publication output of institutions from the US and Taiwan had a higher impact. Of all the papers published 17%, did not get any citations. The incidence of High-Quality Papers, Citations per Paper (CPP) and Relative Quality Index (RQI) were more than average for the USA. The proportion of co-authored papers increased significantly in the year 2008 as compared to 1987. The proportion or mega authored paper was high for the Netherlands, Taiwan, China, Cuba, Brazil, France, and Japan.

Methodology

The present study data were collected from the web of science core collection database which is published by Thomson Reuters [WOS]. The records on 'Dengue Disease' research output during 2005 - 2014 have taken for the analysis. The present study analysis for the authorship pattern, countries, institutions, keywords in dengue disease. Bradford's law of scattering has also been applied in this study. The keywords investigation for dengue disease during the study period was taken and 3517 words were retrieved for the present study. The collected data from a web of science core collection database records of analyzed through Histcite and calculated using excel sheet to find out the result.

Data Analysis and Interpretation

Table 1 analyses the yearly output brought out by the scientists on dengue disease at world level from 2005 to 2014. From the below table, we could clearly see that there is about 3517 total output brought out by the scientists on dengue the year wise analyses indicate the increasing trend. In the year the output measured is 131. It increased to 691 in the year 2014. Yet there is a declaring trend is observed in the year 2013 from the year 2005 to 2009. The output performance rate is measured to below 10 percentages; still, from 2010 onwards the performance is observed to more than 10 percentages. And the year 2014 is a progressive year. The increasing trend is noted from this year 2005 and the light output performance is noted in the year 2014. Yet there is a declaring status in the output performance is observed in the year 2013 to which the reason is unknown. The study includes the data covered in a web of science database from 2005 to 2014.

Table 3 lights on the language wise distribution of research output given by dengue researcher. The overall strong period corers 11 different languages. The dengue scientists are spread over 11 different language speakers. Among then 5 languages are observed. The majority of the scientists prefer publishing their reserved output in English language. It is routed to be about 3376. out of total output of 3517 language English occupies to be the top and it is calculated to 95.93 percentage. The next language that the dengue scientist prefer is Spanish which is accounted to 51.

Table 4 explains the country wise distribution of publications output on Dengue Disease. The total output observed in the study is 5505 during the short period. There are about dengue contras have collective contributed 5505 research output on dengue disease. The analyses bring out the fact that the USA is ranked to be the first and it has given the productivity of 1219 records on Dengue research. The second rank is occupied by BRAZIL which has brought out 430 publications on Dengue Disease. While comparing the output of USA, Output of BRAZIL seems to be one third of USA's Output. The third rank to the UK .It has reflected with 316 publications output. FRANCE is the next order of rank and it has shows 284 publications. India is ranked to the fifth in order. The output of INDIA is accounted to 261. THAILAND is observed to be sixth in rank order with 255 publishing. There are about 5 countries observed with more than 100 publications on Dengue disease. The other countries are noted with less than 100 publications .The table has listed according to the output of countries up to 10 publications. Number of countries has collectively brought out 219 research output on Dengue Disease.

Table 4 shows year wise authorship pattern of the research output on dengue disease. It indicates that out of the 216 contributions to single authors. Year 2014 is highest number i.e-33, since the year 2005 has the lowest number i.e-8 contributions .Out of the 435 contributions to two authors, Year 2014 is highest number i.e-79, since the year 2005 has the lowest number i.e-12 contributions. Out of the 435 contributions to three authors, year 2014 is highest number i.e-94, since the year 2005 has the lowest number i.e-21 contributions. Out of the 370 contributions to four authors, Year 2014 is highest number i.e-64, since the year 2005 has the lowest number i.e-15 contributions.

The table shows the details about the degree of collaboration which indicate tend in single and multiple authorship during 2005 - 2014 as shown in Table. The degree of collaboration ranges from 0.90 to 0.97 and the average degree of collaboration is 0.94. The DC is calculated by using the formula K. Subramaniyam, 1982. The formula is where

DC = Degree of Collaboration

NM = Number of Multi Authors

NS = Number of Single Authors

C = [N.sub.m]/[N.sub.m] + [N.sub.s]

C = 3301/3301 + 216 = 0.93

In the present study the value of DC is 0.93.

As the result, the degree of collaboration in the study Dengue Disease is 9.36 which show the collaborations of multiple authors.

We observed the majority of the keywords DENGUE in 2038 research output with TLCS-10794 and TGCS in-33761 which we got the first position. The next keywords kindly concentrated by the World Scientists on Dengue Disease in 959 records of "VIRUS" which is observed with TLCS 4858 and TGCS in 18481 which we got second position, followed by the "FEVER"462 records with TLCS-2131 and TGCS-6377 which we got the third position.

Further, it was analyzed to find out the key journals in the field of Dengue Disease which have brought out with more number of publications made by the researchers. It was found that there were 840 journals Dengue Disease researchers got their articles published over a period of study. There have been 239 papers published by a single PLOS NEGLECTED TROPICAL DISEASES has published; 0 TLCS, 3892 TGCS. It ranked at first place of research output in the field of Dengue Disease. The second position is taken by PLOS ONE which is accented to 183 publications of Dengue disease researchers in the Indian scientists with; with 0 TLCS, 1504 TGCS. The journal of AMERICAN JOURNAL OF TROPICAL MEDICINE AND HYGIENE 143 Publications, 886 TLCS and 2400 TGCS are scaled and it stands in third position of the publication. JOURNAL OF VIROLOGY has published 94; 1101 TLCS, 3287 TGCS, and it ranked in fourth place. 'VACCINE' has published 62 with 341 TLCS, 1340 TGCS and it stands in fifth position.

Bradford's law of scattering

The aim of Bradford's law is to explain that a group of journals could be arranged in an order of decreasing productivity and this has revealed that journals which yield most productive articles come first while the most unproductive tail last. According to this law journals are to be grouped into a number of zones each producing similar number of articles. However, the number of journals in each zone will increase rapidly. Then the relationship among the zones is l:a:[n.sup.2].

Bradford in his study analyzed articles in Dengue Disease. The journals containing to that field in descending order of productivity and divided that list into three 'Zones' each containing roughly the same number of journals .Bradford observed that the number of journals contributing articles to each zone increased by the multiplications of about five. The distribution of journals in various zones is as follows.

According to Bradford's law of distribution based on equation 1 and 2 the relationship between the zones is l:n:[n.sup.2], But the relationship between the zones in the present study is contradictory in each as 16:77:747 which does not fit to Bradford's distribution. It is clear that core distribution of articles has been published by a very few journals which means less than what Bradford formulated.

Conclusion

From the conclusion of this present study, the efficiency of the author could be recognized. Therefore, the individual author may be stimulated to distribute more number of contributions to enhance the single author contributions. The atmosphere and infrastructure are also very effective for the entire development of 'Dengue Disease' research area. It should be required to necessitate, stimulate and encourage researchers and scientists in this field of 'Dengue Disease' to carry out research to recognize the impact of research output. It is mandatory to recruit specific research institutions to support research in the area on 'Dengue Disease' research in the developing countries. The Universities and research institutions are to be provided with more financial assistance in the form of research grants to increase the quality of research.
