Data on patent and scientific paper is considered as a useful information source for analyzing technological information and has been widely utilized. Technology big data is analyzed in various ways to identify the latest technological trends and predict future promising technologies. Clustering is one of the ways to discover new features by creating groups from technology big data. Patent includes refined bibliographic information such as patent classification code whereas scientific paper does not have appropriate bibliographic information for clustering. This research proposes a new approach for clustering data of scientific paper by utilizing reference titles in each scientific paper. In this approach, the reference titles are considered as textual information because each reference consists of the title of the paper that represents the core content of the paper. We collected the scientific paper data, extracted the title of the reference, and conducted clustering by measuring the text-based similarity. The results from the proposed approach are compared with the results using existing methodologies that one is the approach utilizing textual information from titles and abstracts and the other one is a citation-based approach. The suggested approach in this paper shows statistically significant difference compared to the existing approaches and it shows better clustering performance. The proposed approach will be considered as a useful method for clustering scientific papers.

This article is for understanding relations between the classifications of gastritis and syndrome differentiation types of Korean Medicine through research on syndrome differentiations of clinically applied gastritis and literature of Korean Medicine. Clinical papers were searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI) from 1995 to 2015. Conclusions are as follows. First, disease mechanism of chronic gastritis are qi stagnation, damp stagnation, heat obstruction, blood stasis obstruction, yin damage, damage to collaterals with healthy qi deficiency and pathogenic qi. And qi movement stagnation is shown through the status of chronic gastritis. Second, chronic superficial gastritis belongs to qi aspect syndrome and mainly pathogen excess syndrome. And the key mechanisms are congestion and disharmony of stomach qi sometimes combined with liver depression, food accumulation and dampness-heat. Third, chronic atrophic gastritis belongs to qi-blood syndrome and deficiency-excess complex syndrome with the root of spleen qi deficiency and stomach yin deficiency and the tip of blood stasis, qi stagnation. And key mechanism is damage to collaterals with healthy qi deficiency and toxin-blood stasis. Forth, pathogen excess syndromes are shown at the early stage of chronic gastritis and healthy qi deficiency syndromes after the middle stage. Qi deficiency is shown at the beginning of the disease and yin deficiency at the late stage. And qi deficiency is related with superficial gastritis and yin deficiency with atrophic gastritis.

UAV (Unmanned Aerial Vehicle), the pilotless plane or drone, draws researchers' attention at these days for its extended use to various area. The research was initiated for military use of the UAV, but the area of applicable field is extended to surveillance, communication, and even delivery for commercial use. As increasing the interest in UAV, the needs of research for operating the flying object which is not directly visible when it conducts a certain mission to remote place is obviously grown as much as developing high performance pilotless plane is required. One of the project supported by government is related to the use of UAV for logistics fields and controlling UAV to deliver the certain items to isolated or not-easy-to-access place is one of the important issues. At the initial stage of the project, the previous researches for controlling UAV need to be organized to understand current state of art in local researches. Thus, this study is one of the steps to develop the unmanned system for using in military or commercial. Specifically, we focused on reviewing the approaches of controlling UAV from origination to destination in previous in-country researches because the delivery involves the routing planning and the efficient and effective routing plan is critical to success to delivery mission using UAV. This routing plan includes the method to avoid the obstacles and reach the final destination without a crash. This research also present the classification and categorization of the papers and it could guide the researchers, who conduct researches and explore in comparable fields, to catch the current address of the research.

Purpose: The purpose of this study is to derive the residential environment design elements that affect suicide, and then analyze the actual situation in terms of suicide prevention and suggest implications. Methods: The study was conducted through literature analysis, field surveys, and interviews with stakeholders. Results: As a result of extracting the variables related to the residential environment that affect suicide suggested in a total of 18 papers, 15 variables were extracted and organized into major categories such as housing type, health and welfare facilities, leisure and cultural facilities, and living environment. Next, we selected a public rental housing complex with a relatively high suicide rate among multi-family housing as the case, and conducted a empirical analysis. It was investigated that the facilities were insufficient, and apart from the quantitative satisfaction of the rest, various problems were exposed, such as the classification of users according to age and insufficient management in terms of the actual use of residents including suicide attempters. Implications: First, it is necessary to search for the design direction of the residential environment for suicide prevention. Second, it is necessary to find a way to solve the exclusion phenomenon that appears in space and programs. Third, when planning a space for suicide prevention, understanding of the behavior of high-risk groups should be reflected.

Purpose The purpose of this study is to review topic and survey methodological trends in 'The Journal of Information Systems' in order to present the practical guidelines for the future IS research. By attempting to conduct a meta-analysis on both topic and survey methodological trends, this study could provide researchers wishing to pursue this line of work further with what can be done to improve IS disciplines. Design/methodology/approach In this study, we have reviewed 185 papers that were published in 'The Journal of Information Systems' from 2010 to 2018 and classified them based on topics studied and survey methodologies used. The classification guidelines, which was developed by Palvia et al.(2015), has been used to capture the topic trends. We have also employed Struab et al.(2004)s' guidelines for securing rigor of validation issues. By using two guidelines, this study could also present topic and rigor trends in 'The Journal of Information Systems' and compare them to those trends in International Journals. Findings Our findings have identified dominant research topics in 'The Journal of Information Systems'; 1) social media and social computing, 2) IS usage and adoption, 3) mobile computing, 4) electronic commerce/business, 5) security and privacy, 6) supply chain management, 7) innovation, 8) knowledge management, and 9) IS management and planning. This study also could offer researchers who pursue this line of work further practical guidelines on mandatory (convergent and discriminant validity, reliability, and statistical conclusion validity), highly recommended (common method bias testing), and optional validations (measurement invariance testing for subgroup analysis, bootstrapping methods for testing mediating effects).

Purpose: The purpose of this article is to clearly describe research trends on health life expectancy using oral health indicators that have been published from 2010 to 2020 then suggest the direction of future research. Methods: Online academic databases in English (PubMed, Web of Science and Embase) were used to find those articles by applying a variety of keywords, including terms (adjusted life year, adjusted life expectancy, dental and oral). We identified relevant articles based on the following classification method of Mathers: (1) health gaps, (2) health expectancies. Results: Among 1,728 articles from the online databases, the final 13 studies satisfied the inclusion criteria and were selected for analysis. Health life expectancy studies indicate that research growth was recently achieved overseas. Among the literature collected in this study, 10 studies using health gap indicators yielded seven Disability-Adjusted Life Year (DALY), and three calculated Quality-Adjusted Life Year (QALY), which differed in the nature of the survey data used in the study measuring DALY and QALY. There are only three health expectancies and the number of papers were smaller than the health gap study. Conclusion: Establishing a foundation to calculate health life expectancy indicators through the development and improvement of oral health level are needed. More studies in the area of health life expectancy estimation research is based on actual prevalence and oral health-related quality of life are also needed.
