NTIS(National Science & Technology Information Service) is the first national R&D information knowledge portal service in the world to provide information of government-funded R&D projects and it has been developed by KISTI. This study investigated several limitations of current NTIS information service, analyzed information needs for end users, and then proposed information recomposition and visualization method to satisfy their information needs. For doing this, we firstly clarified the definition of 'end-users' and classified three different groups of general users. We also discriminated various information needs according to three groups and illustrated some examples of visualization results to meet the requirements - 'retrieval simplification' and 'information visualization'. To consider practicality of our proposed method, we suggested implementation plans to utilize existed NTIS services.

Korean e-Navigation is a system that introduced to reduce maritime accidents. In order to reduce marine accidents, Korean e-Navigation provides the following services-"Vulnerable Vessel Monitoring", "Vulnerable Vessel support & monitoring", "Optimal safety route", "ENC Streaming for Small Vessel", "Tug & Barge Support", "Maritime Safety Information Providing". Each Service is a system separated into finctional units and integrated into Korean e-Navigation. Korean e-Navigation is introducing data middleware to integrate each service and the DDS(Data Distribution Service) is judged to be effective. Thus, this paper analyzed the characteristics of DDS middleware types suitable for each service of e-Navigation.

Growing competition is forcing firms to unceasingly achieve innovation for survival. In a response to increased competition, firms invest in R&D. In this vein, this study focuses on the relation between competition and R&D investments of firms. To this end, we decompose competition into actual and potential competition first and then empirically examine effects of each competition on firms' R&D investments. Further, this study also focuses on moderating roles of firms' performance relative to their aspiration level on these relations. By using Compustat data, we found that actual competition hinders firms' R&D investments, but potential competition enhances R&D investments. In addition, the effects of actual and potential competition were moderated by firms' performance relative to their aspiration level. Specifically, negative performance strengthens the negative effect of actual competition on R&D investments, but attenuates the positive effect of potential competition. Moreover, positive performance moderates the effects of each competition in the same direction, but its moderating effects are stronger than negative performance. As such, this research seeks to identify the relations between actual and potential competition and R&D investments of firms and the moderating role of performance relative to aspiration level.

This study analyzes the effectiveness of government supported R&D program for SMEs by measuring TFP improvements. We estimate TFP for Korean companies from 2011 to 2018 using Levinsohn and Petrin (2003) method which reduces endogenous problem. Then government R&D beneficiary companies were extracted from the NTIS and linked to TFP estimates. The empirical results are as follows. First, as a result of estimating production function, the contribution of TFP to value-added is more important than in the past. Second, the TFP gap between large firms and SMEs continues to wide and there is no sign of easing.(from 3.72 times in 2011 to 5.23 times in 2018). Third, SMEs beneficiaries show higher TFP level than non-beneficiaries. However their TFP was on the decline until government support. After government supported R&D program, it reverses upward. Fourth, although one-year TFP improvement of beneficiaries is bigger than non-beneficiaries, it is smaller than the control group through PSME. Because SMEs participating in government R&D programs had showed downward trend of TFP until R&D program, it is necessary to examine whether there is a fundamental discordance between the demand of SMEs for R&D program and governments policy goal. More sophisticated program design will be required to escape the recognition that government R&D programs for SMEs are just charity.

The volume of unstructured text data generated by various social media has been increasing rapidly; therefore, use of text mining to support decision making has also been increasing. Especially, issue Clustering-determining a new relation with various issues through clustering-has gained attention from many researchers. However, traditional issue clustering methods can only be performed based on the co-occurrence frequency of issue keywords in many documents. Therefore, an association between issues that have a low co-occurrence frequency cannot be discovered using traditional issue clustering methods, even if those issues are strongly related in other perspectives. Therefore, issue clustering that fits each of criteria needs to be performed by the perspective of analysis and the purpose of use. In this study, a multi-dimensional issue clustering is proposed to overcome the limitation of traditional issue clustering. We assert, specifically in this study, that issue clustering should be performed for a particular purpose. We analyze the results of applying our methodology to two specific perspectives on issue clustering, (i) consumers' interests, and (ii) related R&D terms.

e-Navigation, which is scheduled to be implemented in 2019 centered on IMO, is actively conducting researches worldwide and various marine systems are being developed. Ship INS will be integrated with various navigation systems such as RADAR, ECDIS, BAM, etc. in order to support e-navigation system, and there is a great need for integrated operation and management. In this research, introduce a research on the integration method of platform - based ship navigation equipment that can operate, expand, maintain and repair various ship systems efficiently.

This paper introduces an online collaboration infrastructure in order to build a nationwide collaboration ecosystem in research and education areas. The proposed infrastructure involves domestic research institutes, education institutions and related commercial service vendors. It also includes various systems and services which can promote their online collaboration. Especially it provides the user authentication framework based on identity federation which facilitates the share of various ICT resources across different organizations, thereby enabling the efficient R&D collaboration. We deploy and validate the user authentication framework of the infrastructure on KREONET.

This study explores the barriers to using health and medical data in research and development (R&D) within the healthcare industry and suggests ways to enhance data utilization. As artificial intelligence technology drives transformative changes across industries, there is an increased demand for robust health and medical data, highlighting its critical economic value and utility in fostering innovation. Using qualitative analysis through Grounded Theory, the study involves ten R&D professionals from healthcare industry, including both medical centers and corporations, using surveys and in-depth interviews to gather diverse experiences and perspectives on the challenges and opportunities in health and medical data use. Key findings point to legislative, regulatory, and data quality and integration issues, as well as complexities in patient data access and usage. Technological limitations and inadequate data governance frameworks also emerge as significant obstacles. Recommendations focus on improving regulatory frameworks, enhancing data standardization and quality, and fostering stronger partnerships between data custodians and users. The study concludes that overcoming these obstacles requires a comprehensive strategy involving legislative changes, improved technological infrastructure, and increased stakeholder collaboration. Implementing these recommendations could greatly enhance health and medical data utilization in R&D, significantly advancing medical science and patient care services.

최근의 방송은 A/V 프로그램만을 보내주던 기존의 방송에서 데이터를 연동하여 서비스하는 방송으로 변화하였다. 데이터 방송은 지상파, 위성, 케이블 등의 방송망을 이용하여 하나의 방송사가 다수의 시청자에게 디지털 멀티미디어 콘텐츠를 여러 종류의 단말기에 전송하는 것이다. 이러한 데이터 방송을 통해 시청자가 직간접적으로 프로그램에 참여할 수 있게 된다. 이러한 서비스를 위해 필요한 여러 기술 중에 사용자의 인터페이스를 제공하기 위한 콘텐츠 표현 기술이 필요하다. 대표적인 콘텐츠의 표현 기술은 HAVi UI와 eTV 시스템이 있다. HAVi UI는 자바 컴포넌트 API로 구성되어 있으며 HAVi 컴포넌트 API로 셋톱박스 어플리케이션(Xlet)을 개발한다. 개발된 Xlet 프로그램은 미들웨어 시스템에 탑재된 자바 가상 머신을 통해 실행된다. eTV 시스템은 범용 마크업 언어인 XML로 어플리케이션을 개발한다. 개발된 eTV 어플리케이션은 eTV 바이너리 생성기를 통해 EBIF가 생성되고 셋톱박스에 탑재된 eTV 리시버에서 실행된다. 본 논문에서는 eTV 시스템을 구성하기 위한 구성요소에서 서버 모듈인 eTV 바이너리 포맷 생성기를 개발하였다. eTV 시스템 개발을 통해서 데이터 방송을 위한 사용자 인터페이스의 기능을 확대 할 수 있으며, 시청자의 선택에 따른 방송을 보다 폭 넓게 제공할 수 있다.
