  • A new study was carried out to utilize a pencil drawing paper sensor (PDPS), which drew a line using a pencil on the paper, as a sensor. The sensing effect on 3 different papers based on the properties of PDPS was compared. The specimens were prepared by drawing 4B pencils on plain (A4), Hwasun, and Han papers. The silver paste was used to give good electrical contacts of the copper wires and the pencil drawn line. The chemical structures of 3 papers for PDPS by FT-IR spectrum analysis were similar and the comparative compact states of each paper were observed by optical microscope. From statistical evaluation of tensile strength using 3 papers, plain paper was chosen to be best for the PDPD. The optimum drawing number of PDPD was determined by changing the thickness of the paper with the drawing number. Electrical resistance (ER) with graphite on 3 different papers were compared. The changes in compression was observed through cyclic compressive test of composite materials, it was possible to predict the degree of strain sensing under compressive test. It leads to expectation of properties.

  • This study clearly defined the idea of convergence of small and medium companies and convergence types and understood convergence case of small and medium companies for each type in order to help enhancement of competitiveness of small and medium companies. The convergence type of small and medium companies accepted two levels including technology and industry and value improvement and creation suggested by Deloitte(2009) and it was classified into technology improvement-market expansion type, technology improvement-market creation type, technology creation-market expansion type, and technology creation-market creation type based on the companies introduced in the excellent casebook of convergence and integration technology development business of small and medium companies(August 2011). As a result, it was shown as 5 cases of technology improvement-market expansion, 4 cases of technology improvement-market creation, 3 cases of technology creation-market expansion, and 1 case of technology creation-market creation among the total 13 cases. Therefore, small and medium companies are focusing on technology improvement than technology creation and market expansion than market creation. What we can understand through cases analysis on convergence types of small and medium company is that it is very difficult for small and medium companies to create new technology or new market through convergence. Thus, small and medium companies consider market expansion through technology improvement as the objective and result of convergence. It is important to create new technology or new industry to cultivate new growth engines of the nation, but policy support that cares about reality of small and medium companies must be considered at the same time.

  • Broadcasting telecommunication convergence service means a service where broadcasting and telecommunication converge. Recently with the advancement of technology, broadcasting telecommunication convergence service has been evolving to provide multimedia contents through various devices including wired and wireless network environment. Up to now, IPTV and smartphone-based convergence services have been dominant, but more developed and evolved technology and media will appear in the future. In order to derive the next generation broadcasting telecommunication convergence service supporting model, this study derives an evaluation model of broadcasting telecommunication convergence service and presents a case of evaluation of 30 demonstration projects supported by the Korean government from 2010 to 2014. In this study, we derive an evaluation model and evaluate the demonstration projects by reflecting the position of the main stake holders of service such as users, experts, and related organizational institutions, away from the existing simple service evaluation method. Expert questionnaire used AHP (Analytic Hierarchy Process) method, and the evaluation results were divided into upper and lower groups to provide key implications by a gap analysis. From this analysis this study suggests guidelines for next generation broadcasting telecommunication service support projects. The next generation broadcasting convergence service business should be based on open platform type in terms of service type. In terms of service media, it should be centered on open devices such as smart phones and smart TVs. In terms of types of business responsibilities, it should be led by public organizations and it is necessary to increase the fund matching ratio by at least 62% when the private sector participates.

  • Many studies have been carried out for the development of big data utilization and analysis technology recently. There is a tendency that government agencies and companies to introduce a Hadoop of a processing platform for analyzing big data is increasing gradually. Increased interest with respect to the processing and analysis of these big data collection technology of data has become a major issue in parallel to it. However, study of the collection technology as compared to the study of data analysis techniques, it is insignificant situation. Therefore, in this paper, to build on the Hadoop cluster is a big data analysis platform, through the Apache sqoop, stylized from relational databases, to collect the data. In addition, to provide a sensor through the Apache flume, a system to collect on the basis of the data file of the Web application, the non-structured data such as log files to stream. The collection of data through these convergence would be able to utilize as a basic material of big data analysis.

  • This study aims to analyze the content and methodological aspects of converging scientific technology and humanities in 233 elementary school STEAM programs developed and publicized from 2012 to 2015, to provide the basic materials and implications for editing and supplementing the development of future STEAM programs or policies, or on-site applications of developed programs. The analysis results show that among the Liberal Arts courses of the STEAM program, including Korean, Social Studies, and Ethics, the level of convergence was lowest in Ethics. This seems to be due to the fact that convergence between scientific technology and humanities tended to emphasize a cross-studies convergence over a content convergence done with a specific purpose. In terms of methodological convergence between scientific technology and humanities, the level of convergence of humanities at a normative level was relatively lower than that at a descriptive level. Although a quantitative comparison of the two methods was not significant, it is rather concerning that due to simply converging descriptive humanities, students may not be so aware of the double-sidedness of scientific technology, despite the discovery of some programs that need re-evaluations of their ethical or normative directions. Moreover, the results showed that the cases of converging scientific technology and humanities at a normative level that were analyzed in the STEAM program can be divided into 'complementation of humanities to utilizing scientific technology' and 'complementation of humanities to research in scientific technology and development.' Based on such research results, the study discusses the development of STEAM programs and policies and directions for editing and supplementing programs on-site.

  • This study the problem of deposition uniformity observed during Mist-CVD deposition experiments. The TRIZ's ADRIGE algorithm, a problem-solving technique, is utilized to systematically analyze the issue and propose solutions. Through problem and resource analysis, technical contradictions are identified regarding the precursor's volume and its path when it encounters the substrate. To resolve these contradictions, the concept of applying the principle of dimensional change to transform the precursor's three-dimensional path into a one-dimensional path is suggested. The chosen solution involves the design of an enhanced Mist-CVD system, which is evaluated for feasibility and analyzed using computational fluid dynamics. The analysis confirms that the deposition uniformity consistently follows a pattern and demonstrates an improvement in uniformity. The improved Mist-CVD equipment is validated through analysis, providing evidence of its feasibility and yielding satisfactory results.

  • Patent information describes the history of technological progress in the relevant field, so it can be usefully used to identify trends in technological development and change and to establish R&D development strategies. This study proposes a method to identify the needs and problems of technology development at the planning stage of the R&D process and to analyze core technologies through patent analysis using Natural Language Processing(NLP) technology. As a big data source, collected patent documents registered in Google Patents for foldable technology, the latest technology in the display industry, and then extracted keywords using NLP analyzer. By classifying the extracted keywords into needs and problems for technology development, developed technology and materials, identified the needs of the market and customers and analyzed the technologies being researched and developed. Unlike previous studies that performed patent analysis, this methodology is different in that it can quickly and conveniently analyze the latest technology trends from big data called patents even if you do not have specialized knowledge and skills in the text mining. This study contributes to the digitalization of the R&D process based on data analysis.
