Yongwon Kim,Shin Park,Hwanpil Lee 한국도로학회 2018 한국도로학회 학술대회 발표논문 초록집 Vol.2018 No.05

The government focuses the innovation paradigm of public institutions on the realization of social value through national tasks. Efforts are now being made to legislate the Framework Act on the Realization of Public Institutions’ Social Value, which allows public institutions to serve as the foundation and check the progress of social value realization plans every year. According to this Act, the government performance review must also reflect efforts and outcomes made to create social value. Traditional public institutions in the road sector are trying to convert social responsibility, job creation and related activities into indicators of social value realization. Social value refers to a “value that can contribute to public interests and community development in all areas including social, economic, environmental, and cultural ones.” This definition commonly used in government policy includes the concept of public institutions’ social responsibility and shared value creation. Here, social responsibility refers to the returning of corporate profits to society for the continued development of a community while shared value creation refers to the solving of a social problem by a company pursuing both economic and social value creation. The performance sharing scheme in particular is regarded as an important tool for companies to create social value. In this regard, this study examines how public institutions in the road sector used the performance sharing scheme. The purpose of this study is also to discover more cases based on this analysis. The analysis so far found the following 5 types of performance sharing schemes in the road sector: (a) service improvement, (b) technology development, (c) conditional purchasing, (d) technology transfer, and (e) performance sharing between multiple parties. Notably, technology transfer or performance sharing between multiple parties means that public institutions provide support to the private sector so that it can take the lead and develop required technology. These instances can be good examples of public institutions serving as the foundation and creating social value by removing new technology entry barriers for small and medium-sized enterprises and supporting the development of the latest prioritized technology or product. Accordingly, there needs to be established a cooperative ecosystem between small, medium, and large companies in a win-win approach to increase the adoption rate of SME support projects and provide more technical advice in the road sector and thereby, to expand the cases of shared growth where outcomes are shared in the road sector.

Investigating the Feasibility of Generic Scoring Models of E-rater for TOEFL iBT Independent Writing Tasks

YongWon Lee 팬코리아영어교육학회(구 영남영어교육학회) 2016 영어교육연구 Vol.28 No.1

The current study reports the findings from Phase 2 of a larger research study undertaken toinvestigate the feasibility of using generic scoring models for e-rater in the context of scoringessays for independent writing tasks for TOEFL CBT and TOEFL iBT. In Phase 1, sixdifferent variants of generic and hybrid scoring models of e-rater were created based ontransformed writing data from three different samples of TOEFL CBT prompts (n1=20, n2=20,n3= 40) with the help of ETS (Educational Testing Service) staff and then evaluated on aseparate sample of seven TOEFL CBT prompts (Lee, 2016). In the present investigation, thesesix generic/hybrid models were used, along with prompt-specific models, to score a total of3,126 essays written for two TOEFL iBT independent writing tasks from a field study and theirperformance was evaluated. Results of the analysis showed that (a) there were relatively smallscore variations among different automated scoring models and (b) similar levels of scoreagreement were achieved between the human-human rater pair and various human-automatedrater pairs, although the prompt-specific model behaved most similarly to the human raters. Interms of criterion-related validity of scores, the human rater scores turned out to be somewhatbetter indicators of test-takers’ overall ESL (English as a Second Language) languageproficiency than the automated scores in general. Nevertheless, the comparative advantage invalidity of human rater scores (over automated scores) seemed to diminish significantly, whenmore direct writing measures, such as scores for TOEFL CBT independent writing tasks, wereused as criterion measures.

Technologies of Future Internet Security by TAIDA and ANP

Yongwon Kim,Yoonjae Lee,이봉규 에스케이텔레콤 (주) 2012 Telecommunications Review Vol.22 No.3

The purpose of this study is to prioritize the important security issues under future internet environment. Therefore,we have carried out a previous research on future internet concepts to select the security factors that threaten future internet environment. Also, based on the TAIDA Methodology, we have made a series of scenarios on future threats,and using the ANP Methodology, we have set the order of priority for security factors that were derived based on the scenario. As a result, four major items - Network, Cloud Computing, Device, and Social Engineering - were formed and twelve sub-items were chosen. Then, the order of priority for security issues from highest to lowest appeared in the order of Wireless Communication, Authentication, Denial of Service, IPv6, Router, and etc. Based on the order above,future studies will be discussed.

New Speaker Adaptation Method Using 2-D PCA

Yongwon Jeong,Hyung Soon Kim IEEE 2010 IEEE signal processing letters Vol.17 No.2

<P>This letter describes a speaker adaptation method based on the two-dimensional PCA of training models. In the method, state and dimension of mean vectors are differentiated, and the covariance matrix is computed dimension-wisely. As a result, the speaker weight can contain different weighting for each dimension of mean vectors. In the isolated-word recognition experiments, the proposed method performed better than both eigenvoice and MLLR, for adaptation data longer than about 15 seconds, due to its more elaborate modeling. The method can also be applied to other PCA-based modeling methods where each training model can be represented as a matrix.</P>

A Text Mining Analysis of Patents and Papers in the Road and Transport Sector for the 4th Industrial Revolution

Yongwon Kim,Shin Park,Jiho Park 한국도로학회 2018 한국도로학회 학술대회 발표논문 초록집 Vol.2018 No.05

This study examined the characteristics of research activities in the road sector via an analysis of patents and papers. For the text mining analysis, this study used keywords that contained the term “highway” and extracted data; 25,306 patents and 11,940 papers were used for the analysis. Along with a paper analysis, there is a 3P (paper, patent and patent) analysis method used to examine papers and patents. The 3P analysis method analyzes patent trends (time series, country, applicant, institution, and so on), original technology patents, the latest technology trends in the field of interest, and research trends by examining and evaluating key patent rights and their technology and utilization values. More specifically, analyzing patents owned by companies and papers published based on data obtained from text mining, allows researchers to compare intellectual property competitiveness by institution and identify a competitor’s research trends. Based on the results, commercialized tech areas and global research activity trends can be identified to establish a technology strategy. In this regard, this study used keywords only related to “highway” and acquired the following analysis results: To begin with, some of the most noteworthy research and development areas in the road and transport sector recently included “traction hybrid battery,” “information navigation date,” and “navigation determination.” This suggests great implications. Thus far, the road and transport section has traditionally researched “Construction of Roads, Railways, or Bridges” in Section E (Fixed Constructions) of the International Patent Classification and supporting works such as the installation of supports for the road or the construction of platforms, snow fences or similar arrangements. This study, however, found that lately, a lot of research is being conducted on systems such as transport control systems, transport safety, transport control radars or similar systems, sonar or Light Detection and ranging system, and anti-collision systems. In addition, as smart toll collection increasingly becomes available, a lot of research in the field of physics is being undertaken on transmission methods for measures, control signals or similar signs, and ticket dispensers or devices to collect tolls and admission fees. In conclusion, based on the above findings, this study was able to identify that more research in the road and transport sector is being conducted on smart toll collection and tech convergence such as physics and systems than traditional civil engineering as today’s world is heading towards the 4th Industrial Revolution.
