The 'convergence service' in NGN implies the integration of services in NGN with a unified manner to access each service in order to interwork with each service. This paper shows the convergence model for NGN based on Web Services and provides a detailed scenario of each convergence model in form of Web Services.

The purpose of this study was to specifically explore the dilemma posed by lifelong education for the disabled in Korea at the point of convergence. Research to achieve the research objectives consisted of areas that should be considered in developing and implementing support systems for lifelong education for the disabled. The outcome of the area consisted of five things: convergence dilemmas in fields, convergence dilemmas in institutions, convergence dilemmas in eligibility, convergence dilemmas in disability areas, and convergence dilemmas in national administration. And the five areas were considered by interlinked views and contexts. Based on the results of the study, the university's special education department (including vocational special education) was concluded and considered with emphasis on strengthening the role functions of the university's special education system for the support system for lifelong education for the disabled, including the preconditions for establishing the academic identity of lifelong education for the disabled. Through this ideal, it is worth suggesting that the academic identity of lifelong education for the disabled should be established as appropriate based on convergence between the categories of lifelong education and special education based on the practical nature and context of education for the Korean.

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.

Technological convergence is yielding new values and affecting various fields not by single technology but by convergence between technologies. This study aims to analyze the IT -BT-NT convergence and differences between technologies in respect of collaboration within (inventor) and between (assignee) organizations. Among the main technologies leading the technological convergence, IT is the most active of converging with other fields. BT is knowledge-intensive and strong cooperative networks are important in this area. NT is applied in various industrial fields upon the basic technology. Using the data on applied and granted patents by Korean applicants in the U.S., this study conducted quantitative analysis and ANOVA to gain the following results. First, the degree of convergence in between IT-BT-NT is continuously increasing since 2002. Second, BT is where the collaboration within and between organizations is the most active among IT-BT-NT. Third, there were certain differences in the degree of convergence according to the years and the fields of technologies in all the IT-BT-NT. Organizations cooperate with other institutions to sustain their competitiveness with limited internal resources. Companies in these fields are recommended to perform diverse strategies to pursue further collaboration with the outside.

The Ministry of Agriculture, Food, and Rural Affairs is currently pushing forward policies targeting the Rural Convergence Industry initiative to incubate the front-runners of the '6th industry', to increase off-farm income, to create rural jobs for elderly, and to create women-based farms. As a result, in 2017, a total of 11,604 Rural Convergence Industries were in business, and the goods produced from those industries were diverse. However, the quality and safety of those products are not being checked and managed thoroughly, which has caused consumers to not trust products made from the Rural Convergence Industries. Through a survey and the ordering logit model, this study analyzed consumer perception of the safety and quality of goods from the Rural Convergence Industries. The analysis revealed that we must first raise awareness of the importance of rural agriculture areas and the products of the Rural Convergence Industries to uplift consumer perceptions regarding the products produced by the industries. The analysis also revealed that diverse points of distribution (sellers), education on the importance of rural and urban areas, and marketing Rural Convergence Industry products within suburban consumer populations are necessary to increase the consumption of these products.

The convergence of traditional industry and ICT is a combination of security threats and vulnerabilities in ICT and specific industry-specific problems of existing industries, and new security threats and vulnerabilities are emerging. In particular, in the medical ICT convergence industry, various problems regarding user authentication are derived from the medical information system, which is being used for abuse and security weaknesses. According, this study designed and implemented a user authentication system for secure user management in medical ICT convergence environment. Specifically, we design and implement measures to solve the abuse and security weaknesses of ID sharing and to solve the inconvenience of individual ID / PW authentication by performing user authentication using personalized devices based on medical information systems.

Very compact 4-channel 200-GHz-spacing external cavity lasers (ECLs) were fabricated by hybrid integration of reflection gratings and superluminescent laser diodes on a planar lightwave circuit chip. The fifth-order gratings as reflection gratings were formed using a conventional contact-mask photo-lithography process to achieve low-cost fabrication. The lasing wavelength of the fabricated ECLs matched the ITU grid with an accuracy of ${\pm}0.1$ nm, and optical powers were more than 0.4 mW at the injection current of 80 mA for all channels. The ECLs showed single mode operations with more than 30 dB side lobe suppression.
