This paper proposes the newly developed a classification scheme for Management of Technology (MOT) research, by analyzing research papers published in major academic journals of MOT. To refine our proposed classification, we conducted a contents analysis after collecting 696 papers published in 11 major international journals and 2 representative domestic journals including Journal of Korean Technology Innovation Society, from 2006 to 2012. Our findings show that this classification scheme is composed of total 8 methodologies within each research design such as conceptual qualitative, empirical qualitative, conceptual quantitative, and conceptual quantitative researches. In addition, we provide research reviews based on characteristics between 1) domestic and foreign researchers, 2) domestic and international journals, and 3) different major domestic journals as follows. Firstly, the underlying trends of research design and methodologies in MOT research are concentrated in empirical studies regardless of the origin of researchers and journals. However, the proportion of theoretical discussion in the international journals is higher than that of theoretical discussion in the domestic journals. Secondly, there are many more empirical qualitative researches and archival researches written in the Journal of Korean Technology Innovation Society, whereas the proportion of empirical quantitative research and conceptual research published in the Journal of Technology Innovation is higher than that. From the results, this paper will contribute to choosing research designs and methodologies more suitable to research purpose for future MOT researchers and provide the direction for concrete systematic approach on research designs and methodologies.

The purpose of this research is to contribute to clinical researches on neck pain and cervical spondylosis by reviewing the latest research trends and evaluation tools through the analyses of clinical studies on neck pain and cervical spondylosis over the last 5 years. 70 papers satisfying the selection conditions among the RCT papers that had been searched as "neck pain" or "cervical spondylosis" at Pubmed(https://www.ncbi.nlm.nih.gov/pubmed) from March 2011 to February 2016 were targeted. Papers were numbered in order of their publication dates and analyzed by classifying their contents into 1) pain classification, 2) treatment type, 3) treatment duration, 4) treatment time, 5) number of participants, 6) evaluation tools and methods of research, and 7) evaluation duration. 55 papers targeted chronic neck pain, 6 papers acute and subacute neck pain, and 2 papers subacute and chronic neck pain. In comparison by intervention, 43 papers corresponded to physical therapy, 3 papers to acupuncture, 1 to herbal fomentation, 5 to medication, and 18 papers corresponded to multilateral comparisons comparing the efficacy by various interventions. In research period, there were 50 papers based on treatment period, 16 papers based on the number of treatments, and 4 papers based on different periods depending on each group. In treatment duration, the cases from 1 month or more to less than 3 months were most, followed by the cases of less than 1 month, and the cases from 3 months or more to less than 6 months. In treatment frequency, the number of treatments of the treatment group was the same as that of the control group in 51 papers, and many treatments were conducted by the methods of acupuncture, manual therapy, and injection therapy in cases of once or twice of treatments, and physical therapy and electroacupuncture corresponded mainly to the cases from 3 times or more to less than 10 times of treatments, and retrospective observation and exercise programs corresponded mainly to the cases of more than 30 times of treatments. In the number of subjects of the researches, the cases from 50 or more to less than 100 were most, followed by the cases from 20 or more to less than 50. There were 7 evaluation tools cited 10 times or more: VAS, NRS, PPT, NDI, NPQ, CROM, and SF-36. In evaluation period, 37 papers evaluated only during the treatment period, and 33 papers conducted follow-up. In follow-up period, the cases of less than 3 months were most, followed by the cases from 6 months or more to less than 1 year, and the cases from 3 months or more to less than 6 months. When planning clinical researches on cervical pain in the future, appropriate intervention methods, frequency and duration of treatment, period of follow-up, appropriate number of subjects and selection of evaluation tools for objective validity will have to be considered. In addition, randomization, double-blind, etc. will have to be considered for researches with high basis level.

Objectives : The purpose of this study is to review the chinese published papers on cauterization of traditional chinese medicine. Methods : We searched chinese published papers from 1958 until May 2017 via CNKI(China National Knowledge Infrastructure) with the keyword "cauterization". We analyzed the studies covered cauterization medical treatment, and classified them by 5 categories including periods, type of study, treatment site, experiment target site, and cauterizing method. Results : We reviewed 112 chinese papers which include 10 Original articles, 43 Review articles, and 59 Case reports. Examining yearly distributions, we can see that research on cauterization is becoming more active than in the past. In classification of 93 clinical studies by treatment site, the number of research on Tonsillitis accounts for almost half(43 studies), followed by Sore throat(14 studies). Among 10 experimental studies, Eye is the most frequently targeted organ which was used to study high intra-ocular pressure(5 studies), and retinal ganglion cell(2 studies). Lastly, there are various methods of cauterization used in papers: Branding iron(54 studies), and Red-hot needle(24 studies) are two major heating methods. Conclusions : This analysis shows that studies on the application of cauterization have been actively conducted in China these days. Furthermore, up-to-date cauterizing methods have been developed such as electric type and microwave type beyond traditional ways. We expect this article will encourage further research on cauterization in order to apply it to a variety of diseases. Then, it could become one of new effective medical treatments in Korean medicine.

Objectives The purpose of this review is to analyze the trends of Korean medicine treatment for trigger finger. Methods Clinical papers using Korean medicine to treat trigger finger were searched in five online databases-Koreanstudies Information Service System, Oriental Medicine Advanced Searching Integrated System, ScienceON, Research Information Sharing Service, and PubMed. Nine studies were selected, and we analyzed their characteristics according to the author, year, number/gender/age of patients, duration of disease, duration of treatment, intervention method, measurement methods, and results. Results Seven case report studies, one prospective observational study, and one randomized controlled trials (RCTs) were selected in online databases, and there were no review studies. The most frequently used therapies were pharmacopuncture and acupuncture treatment. visual analogue scale, Quinnell's classification of triggering, was frequently used for measurement methods. All nine studies had therapeutic effects. Conclusions We reviewed studies of Korean medicine treatments for trigger finger, in this study. However, there are limitations that seven of the nine selected papers were case papers, and the number of papers was small. This paper suggests that a higher level of research and more studies on Korean medicine treatments of trigger finger need to be conducted.

According to Wayne A. Wiegand in the 1998, he research to The "Amherst Method": The Origins of the Dewey Decimal Classification Scheme. Although a debate about the origins of the Dewey Decimal Classification Scheme has been going on for generations, historical consensus remains elusive. This paper contributes information to the historiography on the origins of the scheme: 1) by grounding an account of Dewey's thinking as he was crafting the DDC on an analysis of a large body of sources than previous classification historians have consulted; and 2) by expanding and deepening historical understanding of the contextual forces influencing on the classification structure. Because the DDC idea as it first occurred to M. Dewey in Amherst in 1872-73 is an important in the history of library development in the world. He outlined the first draft of his decimal scheme and submitted it to the Amherst College Library Committee on 8 May 1873. This paper analysis to "Three Genetic Paper", that is 1) The Merits of the System, 2) Library Classification System, 3) Its Special Adaption to our Library.

Several studies on the use of Support Vector Machines (SVMs) for diagnosing rotating machinery have been successfully carried out, but the fault classification depends on the input features as well as a multi-classification scheme, binary optimizer, kernel function, and the parameter to be used in the kernel function. Most of the published papers on multiclass SVM applications report the use of the same features to classify the faults. In this study, simple statistical features are determined on the basis of time domain vibration signals for various fault conditions, and the optimal features for each fault condition are selected. Then, the optimal features are used in the SVM training and in the classification of each fault condition. Simulation results using experimental data show that the results of the proposed stepwise classification approach with a relatively short training time are comparable to those for a single multi-class SVM.

This paper is related to detection and classification for micro-sized aircraft that flies at low-altitude. The deep-learning based method using sounds coming from the micro-sized aircraft is proposed to detect and identify them efficiently. We use MFCC as sound features and CNN as a detector and classifier. We've proved that each micro-drones have their own distinguishable MFCC feature and confirmed that we can apply CNN as a detector and classifier even though drone sound has time-related sequence. Typically many papers deal with RNN for time-related features, but we prove that if the number of frame in the MFCC features are enough to contain the time-related information, we can classify those features with CNN. With this approach, we've achieved high detection and classification ratio with low-computation power at the same time using the data set which consists of four different drone sounds. So, this paper presents the simple and effecive method of detection and classification method for micro-sized aircraft.
