  • There has been growing interest in the methods for measuring the credits of individual authors in multi-authored research papers in response to the increase of research collaboration. Having a good understanding for academic norms of individual discipline is essential to measure author credit effectively. However, many Korean universities do not consider different norms for determining the order of authors across disciplines. Rather, they tend to use a standardized method to assess the credits of authors in multi-authored papers. Therefore, this study presented some problems of applying a standardized method to measure author credits in multi-authored papers in economics. The findings of this study confirmed the frequent use of alphabetical author order in economics papers; however, many university guidelines for research evaluation do not take account the alphabetical authorship in measuring the credits of authors. The authors suggest the needs for (1) establishment of a clear definition for primary authors, (2) flexibility in assessment methods for author credit, and (3) empirical research on author credit.

  • In order to review the studies related to the facial pain by acupuncture, we have referred to a PubMed site by using MeSH searching word of "facial pain and acupuncture". 12 journals with 20 papers were reported on the facial pain and acupuncture. Among them, 4 papers were appeared in Am J Chin Med, 3 in Acupunct Electrother Res, 2 in Br. Dent J, J Orofac Pain and Swed Dent J respectively, and 1 in 7 journals respectively. According to the classification of the patterns, 15 papers were done by clinical studies, 2 by review and meta-analysis respectively, and 1 by experimental study. TMD was the most disease that related to facial pain and CMD, neurogenic facial pain (trigeminal neuralgia, postherpetic pain), dental pain and MPS were also appeared. Most of the studies didn't mention the acupuncture points, L14 Habkok in 4 papers and ST36 Chogsamni in a paper were only mentioned. Various modalities were applied in the trials such as classical acupuncture, electroacupuncture, TENS, SSP and auricular acupuncture. By the above results, we concluded that various acupuncture techniques are used with effectiveness on the facial pain. It would be needed further research on the acupuncture point specific and therapeutic techniques as well.

  • The international collaboration on marine biodiversity increases in the proportion of the world's scientific papers produced with more than one international author, 2006-2010. The number of scientific papers from 2006 to 2010 describing "marine new species (or spec. nov., n. sp.)" published 401 (international ranking : $13^{th}$) by S. Korea, 824 ($7^{th}$) by China, 1,249($5^{th}$) by Japan, 1,282($3^{rd}$) by Austrailia, and 3,679 ($1^{st}$) by United States. The papers having an international co-authorship account for 52.0% by S. Korea, 79.0% by China, 67.0% by Japan, 81.0% by Australia at the same period. The proportion of national publication output produced in collaboration with other countries differs proportionately between countries. In S. Korea, the overall numbers of international collaboration were not growing significantly. Both in Japan and China, an overall numbers of international collaboration increased well in accordance with the proportion of national output with international collaboration.

  • Objectives : This study was designed to collect the latest papers and to find more effective approach for childhood obesity. Methods : We searched 107 papers in English from Pubmed(www.ncbi.nlm.nih.gov) and selected 52 in favor of our study. In addition to that, we searched 29 papers in Chinese from www.cnki.net. Results are as follows. Results and Conclusions : There are not completely new treatments for childhood obesity. Instead of that, many studies aimed for prevention through family education, nutrition education, and exercises education. Specially, because some diseases including hypertension, diabetes and heart disease are connected with obese children, medication can be prescribed optionally. In that case, their mental health must be laid emphasis. And in China, TCM(Traditional Chinese Medicine) is very common treatment for childhood obesity. Acupuncture, herb medication and manual therapy could be used usefully. It is suggested that above latest treatments can be combined with Korean traditional treatments method in treating obese children.

  • Every researcher wants their research to gain more recognition, and this desire is achieved by publishing their article in a journal with higher impact. It is very important to get researchers interested in the Journal of Korean Neurosurgical Society (JKNS). Therefore, the first goal was to promote the publication of papers in our journal. To do this, a table of contents was sent out, and the citation ranking was announced every 2 months. Several efforts have been made to publish good papers. Foreign speakers, who were invited to a conference hosted by the Korean Neurosurgical Society were contacted and politely requested to write a paper addressing their recent research. Domestic and international researchers highly renowned in their fields were also contacted to submit their novel works to our journal. The journal impact factor of our journal has continued to rise for the last 3 years and reached 1.376 in 2019. It can be said that the JKNS is now competitive with other international neurosurgery journals. These achievements were not due to the efforts of the editorial boards alone. This was because our society members have submitted very good papers, and because many of our members have cited the papers published in our journal. We believe that this will continue in the future. The next step of evolution of the JKNS has begun, and this is the beginning of another great development.
