  • This study examines the Personalized Oriented Customized and services in smart environments. In addition to The structure of industry is currently smart environment shifting from the manufacturing industry focusing on goods production to service industry merging and combining service and marketing. The companies are placing a higher value on the customer needs to gain a competitive edge with creation of new business model. The key dilemma in mass customization and service, though, is how product customization can be realized without increasing production cost significantly. The purpose of this study is to explore new product development strategies that facilitate mass customization and service. Specifically, we propose Crowdsourcing marketing, Digital experience technology, Recommender Systems, 3D printing technology, Flexible manufacturing systems and UX based PSS(Product-Service Systems) in new product development processes as enabling strategies for mass customization and service in smart environments.

  • Despite huge significance of public policy information to a country and its people, it seems that Korean government lacks a nationwide service that specializes in managing those information. Nowadays the organization of the central government is very complicated and the amount of information and data they are producing is massively growing. Naturally, without any advanced knowledge, it is not easy to find the information you want from the government information service. Besides, government publications are scattered and not under control of unified collection. This study suggests an efficient policy information service model that can i) provide stepping stones for a competent knowledge-based government by providing necessary information for policy-making process in government ministries and public organizations, ii) build national policy information infrastructure by incorporating policy-related information dispersed over different ministries, and iii) identify new approaches to improve policy information services.

  • Recently, the cosmetics industry considers male customers as a consumptive, active customer base who also have purchasing power with their stronger desire for their personal image enhancement. Male-preferred image brands have entered the era of unlimited competition through social media, thus increasing the acquisition of male beauty. Therefore, the information for designing favorable image strategies should be examined. This paper examines male awareness, determined by the degree of appearance management based on four categories (i.e., hair and skin care, makeup, foot and hand care, and plastic surgery). Based on the research, the paper proposes a data service to address the spatial and temporal separation problem between TV CF (the major media for recognizing information) and online $caf{\acute{e}}$/blog the major media for obtaining detailed information.

  • Creating more efficient and effective intermodal transportation service in Northeast range is a critical issue because of more increased trade volume & demand for intermodal service in the world market and geographical barriers associated with goods transportation, especially in Korea, China and Japan. This study examines the possibility of Rail-ferry introduction and possible route in Northest area which can provide each country mutual economical and logistical satisfaction. But, this study requires more empirical and concrete examination based on the cost & benefit analysis.

  • As e-commerce has led to profound changes in the way economic transactions are made and has spurred the rapid integration of global markets, governance of e-commerce has emerged as an important policy agenda around the globe. Given the broader social and economic implications of e-commerce, it is of no surprise that the rule-making process for global e-commerce has increasingly captured the attention of scholars. Despite the substantial contributions to understanding this process, a review of the literature reveals some weaknesses in the study of emerging forms of governance in global e-commerce. This paper addresses these weaknesses and proposes an alternative theoretical framework that underscores the role of ideas and discourse in the global rule-making process.

  • It is only natural, given that the competition environment and policy priorities in the telecommunications market vary from one country to another, that methods for assessing the cost of universal service obligations differ as well. In Korea, with the introduction in 2004 of LRIC for assessing the universal service cost, the national telecommunications authority is preparing for a substantial revision of the current cost assessment method, and discussions on details of changes to be introduced are in full swing. This paper will study estimation methods for universal service costs adopted by countries around the world and compare practices concerning two of the major issues surrounding the assessment of universal service obligation cost - universal service cost ceiling and intangible benefits - to provide directions for changes to be introduced to Korea's own cost estimation model.

  • The mutual exclusion is originally based on the theory of race condition prevention in symmetric multi-processor operating systems. But recently, due to the generalization of multi-core processors, its application range has been rapidly shifted to parallel processing application domain. POSIX thread, WIN32 thread, and Java thread, which are typical parallel processing application development environments, provide a unique mutual exclusion mechanism for each of them. Applications that are very sensitive to performance in these environments may want to reduce the burden of mutual exclusion, even at some cost, such as inconvenience of coding. In this study, we implement Dekker's and Peterson's algorithm in the form of busy-wait and processor-yield in various platforms, and compare the performance of them with the built-in mutual exclusion mechanisms to evaluate the usability of the classic algorithms. The analysis result shows that Dekker's algorithm of processor-yield type is superior to the built-in mechanisms in POSIX and WIN32 thread environments at least 2 times and up to 70 times, and confirms that the practicality of the algorithm is sufficient.

  • 건물일체형 태양전지 (BIPV; building integrated photovoltaics)나 야외 태양광 발전 차양 등의 태양광 발전에는 기존의 유리 기판 태양전지보다 가볍고 유연한 flexible 박막 태양전지가 설치하고 운영하는데 적합하다. 이러한 flexible 박막 태양전지는 자동차나 휴대기기의 전원이나 배터리의 충전기기로도 쓰이며 그 수요가 증가 추세에 있다. 특히, flexible Cu(In, Ga)$Se_2$(CIGS) 박막 태양전지는 기존의 flexible 실리콘 박막 태양전지보다 효율이 높아서 앞으로 성장 잠재력이 매우 높다. 세계적으로도 많은 기업이 상용화를 추진하고 있으며, 2007년부터 시장에 진입하고 있다. 그러나 현재의 flexible CIGS 박막 태양전지는 유리 기판 CIGS 박막 태양전지보다 효율이 낮고 패키지를 유리에서 플라스틱으로 대체하기 때문에 수명이 짧다. 또한, 아직도 완전한 양산 체제로 전환이 이루어지지 않았기 때문에 해결해야 할 문제점이 많이 있다. Flexible 기판으로는 스테인리스 스틸이나 폴리머 기판이 사용되는데, 유리 기판에 비해 저가 태양전지를 제조할 수 있을 뿐만 아니라 roll-to-roll 공정을 적용할 수 있어 가격 경쟁력을 확보할 수 있다. 특히, 금속 유연기판을 사용할 경우, 유리 기판에 비해 상대적으로 고온 공정이 가능한 장점이 있다. 그러나, 금속 기판을 사용할 경우 해결해야 할 두 가지 이슈가 있다. 첫째, CIGS 흡수층 형성에 도움을 주는 Na의 공급 문제이다. 유리 기판의 경우 기판에 포함되어 있는 Na이 확산을 통해 공급되지만, 금속 기판의 경우 별도의 Na 공급 방법을 고려해야 한다. 둘째, 불순물 확산 방지막 및 전기 절연층으로 사용되는 유전체 박막의 문제이다. 현재 다양한 금속 산화물 유전체 박막을 사용한 연구가 진행되고 있다. 본 논문에서는 flexible CIGS 박막 태양전지의 기술적 이슈 및 현재 연구 현황을 살펴보고, 스테인리스 스틸 기판을 이용한 CIGS 박막 태양전지에서 유전체 확산 방지막에 따른 특성을 비교하고자 한다. 스테인리스 스틸 기판의 불순물로부터의 확산을 방지하기 위하여 두 종류(intrinsic ZnO와 SiOx)의 유전체 박막을 각각 Na가 도핑된 Mo층과 스테인리스 스틸 기판 사이에 삽입하여 소자를 제작하였다. 확산 방지막이 없는 경우, SiOx층을 사용한 경우, 그리고 intrinsic ZnO 층을 사용한 경우에, 효율은 각각 7.47, 11.64, and 13.95%로 나타났다. 셀의 크기는 $0.47\;cm^2$이고, 반사방지막은 사용하지 않았다.

  • The government-supported research institutes' system seems to face a turning point as the country's innovation system, shaped in the industrialization process, now reveals its own limitations. This makes the transformation of the innovation system unavoidable. Korea began to emerge as a leader in several technological areas including semiconductor, TFT-LCD, and handset, in a few cases even outpacing advanced countries. This has changed the very nature of the problems and questions to be resolved. This study analysed the structural limitations and challenges of government-supported research institutes focused ETRI. In a nutshell, The innovation system of government-supported research institutes seems to face a situation where the new innovation environment is conflicting and competing with the legacy of the past: governance, planning, budget, personnel, evaluation system. There are needs for change and thus tries to achieve a innovation system transition and build a new vision and management system including a new mode of working for post-catchup innovation.
