R&D 기획은 연구 개발 전주기에 있어 수행, 평가에 앞서 필수적으로 선행되어야 하는 행위이다. 그렇지만, 아직까지 R&D 기획에서 무엇을 다루어야 하는지에 대한 원칙, 사례만 존재하고 이를 통합 시스템화하지 못하고 있어, 대부분의 연구자들은 논문, 특허, 웹을 포함한 다양한 자원들로부터 정보를 수집, 취합, 분석하는 데 많은 시간을 뺏기고 있는 형편이다. 이 문제를 해결하기 위해서 본 연구 이전에 시맨틱 기술과 텍스트 마이닝 기술을 이용하여 R&D 전략 수립을 지원하고자 InSciTe, InSciTe Advanced 등이 개발되었지만, R&D 기획이라는 궁극적 목적 내에서도 사용자마다 다양한 시나리오들을 분별하여 지원하기에는 어려움이 많았다. 이에 본 연구는 사용자 적응적 가이드 방식을 통합적으로 적용하여 실시간으로 변화하는 사용자 관심을 파악하고, 대표적 시나리오들에 맞추어 사용자가 목적을 효과적으로 달성할 수 있도록 지원하는 데 초점을 맞추고자 한다. 먼저 사용자 적응적 가이드 방식의 R&D 기획 시스템 구축을 위해 필요한 요구 사항들과 이들을 효과적으로 시스템에 반영하기 위한 온톨로지, 웹 서비스 중심의 설계 원칙들을 제시함으로써 R&D 기획뿐만 아니라 타 분야에서도 유연하게 적용할 수 있는 기반을 제공한다.

Recently, Service-Oriented Architecture(SOA) is on the rise to reduce the complexity of IT infrastructure, minimize cost for maintaining it and maximize the productivity and flexibility in business. SOA increases the adaptability by loosely coupling and it's main feature is that three elements such as service provider, service requester and service registry are connected with each other systematically. These make difficult to adopt traditional development methodologies to implement SOA. In this paper, we suggest a service-oriented development process with regard to the aspect of service provider and service requester. The process consists of six phases and each phase sets up with guidelines and artifacts. It can choose the process type along with the goal in Development Planning.

In order to maintain customer satisfaction and to remain productive and efficient in today's global competition, mass customization is adopted in many leading companies. Mass customization through product family and product platform enables companies to develop new products with flexibility, efficiency and quick responsiveness. Thus, product family strategy based on product platform is well suited to realize the mass customization. Product family is defined as a group of related products that share common features, components, and subsystems; and satisfy a variety of market niches. The objective is to propose a product family design strategy that provides priority weights among product components by satisfying customer requirements. The decision making process for a new product development requires a multiple criteria decision making technique with feedback. An analytical network process is adopted for the decision making modeling and procedure. For the implementation, a netbook product known as a small PC which is appropriate for the product family model is adopted. According to the proposed architecture, the priority weight of each component for each product family is derived. The relationship between the customer requirement and product component is analyzed and evaluated using QFD model.

Web-based information resources should be managed and used methodically in the same manner as the paper-based resources are managed and used. It is necessitated by the prevalence of web-based delivery of a variety of information. To develop a web-based digital collection, it is critical to establish a set of standardized evaluation criteria for web-resources. The evaluation criteria needs to include authority, trustworthy, reliability, functionality, relatedness, accessibility, structure, design, user support, and security related matters. However, it is also necessary to have certain flexibility to either emphasize or include particular evaluation criteria to reflect varying characteristics of the web resources especially for the purpose of developing an effective digital collection. In addition, it is essential to review the evaluation criteria with respect to value, demand, duplication prevention, and intellectual property, which are relevant to the web-based digital collection development. Finally, various strategies were suggested as means to develop more effective web-based digital resource collection. These strategies include organizing a selection committee to ensure the objectivity and consistency in web-resource evaluation; developing a model for web-based digital resource collection; sharing new standards, protocols, markups, and metadata with other digital libraries; and developing user-centered digital resource collection.

Intensive pulsed light (IPL) technique enables energy to be transferred to a target substance in a short time per millisecond at room temperature under an ambient atmosphere. Due to the growing interest in flashlights with excellent functionality among various technologies, light-sintering research on metal particles using IPL has been carried out representatively. Recently, examples of the application of IPL to various material synthesis have been reported. In the present article, various strategies using IPL including the manufacture of flexible electrodes and the synthesis of metal-organic frameworks were discussed. In particular, the process of improving oxidation resistance and electrical conductivity of electrodes, and also the metal-organic framework synthesis from metal surface were explained in detail. We envision that the review article can be of great help to researchers who investigate electrode manufacturing and material synthesis using IPL.

This paper attempts to determine the most reasonable and agreeable option for new MRV framework in Post-2020 Climate Regime as well as to develop South Korea strategies to reflect our national circumstances and capacities appropriately. The options for MRV framework considered here are 1) Dual MRV and 2) Unified MRV. We reached the conclusion that the Unified MRV framework may be the most reasonable option in the 2015 agreement in line with the objectives of MRV. To this end, it is essential to develop effective stepwise strategies consisted of: 1) reaching a consensus internally on the Unified MRV framework, 2) developing detailed procedures and methodologies to make the major elements of the Unified MRV framework understandable and predictable, 3) delivering an overview and blueprint to make sure of the flexibility of the Unified MRV framework to reflect the Parties' capacities and national circumstances, 4) ensuring the financial and technical support schemes for developing countries to improve the capacity-buildings of MRV, and 5) developing a realistic road map to successfully implement the Unified MRV scheme within the required time frame. Korea, as a rational mediator between developed and developing countries, should play a leading role in reaching post-2020 agreement.

The utilization of the achievements derived from the national R & D project is a key task of the science and technology industry policy that should lead the national economic growth by enhancing the investment efficiency of the national R&D. Although Korea has implemented various programs supporting technology transfer, commercialization, Performance is not sufficient. One of several causes may include inflexibility of a small or medium-sized company Priority System. This study is exploratory research on the directions for improving the current a small or medium-sized company Priority System. Results: First, Because the current SMEs Priority System contributes positively to enhancing SMEs R&D capability, We have to keep the system in principle. However, it is necessary to improve the direction of giving the strategic flexibility of the system so that the system is not operated formally. First, it is appropriate to make an exceptional contract with a person other than a small or medium-sized company, if a small and medium-sized company is not suitable for a technology execution contract due to the nature of technology. Second, it is desirable to consider the fulfillment of the obligations of this system when "sufficient efforts" are made to find a technical user.

The robot soccer simulation game is a dynamic multi-agent environment. In this paper we suggest a new reinforcement learning approach to each agent's dynamic positioning in such dynamic environment. Reinforcement learning is the machine learning in which an agent learns from indirect, delayed reward an optimal policy to choose sequences of actions that produce the greatest cumulative reward. Therefore the reinforcement learning is different from supervised learning in the sense that there is no presentation of input-output pairs as training examples. Furthermore, model-free reinforcement learning algorithms like Q-learning do not require defining or learning any models of the surrounding environment. Nevertheless these algorithms can learn the optimal policy if the agent can visit every state-action pair infinitely. However, the biggest problem of monolithic reinforcement learning is that its straightforward applications do not successfully scale up to more complex environments due to the intractable large space of states. In order to address this problem, we suggest Adaptive Mediation-based Modular Q-Learning (AMMQL) as an improvement of the existing Modular Q-Learning (MQL). While simple modular Q-learning combines the results from each learning module in a fixed way, AMMQL combines them in a more flexible way by assigning different weight to each module according to its contribution to rewards. Therefore in addition to resolving the problem of large state space effectively, AMMQL can show higher adaptability to environmental changes than pure MQL. In this paper we use the AMMQL algorithn as a learning method for dynamic positioning of the robot soccer agent, and implement a robot soccer agent system called Cogitoniks.

The development of ICT brings a big change in manufacturing industries, and new information technology such as IoT, AR, and big data was applied on manufacturing process. As a result, the concept of smart factory has been introduced as a new manufacturing paradigm. In fact advanced countries like USA, Germany, and Japan have actively introduced smart factory in their manufacturing industries such as electronic, automobile, machinery, to improve production efficiency and quality. The manufacturing environment has been changed into flexible system, so that smart factory will be leading future manufacturing industries. Thes changes have more severe influence on Korean manufacturing industries. Mny industrial companies, have a strong interest in smart factory and they, particularly big enterprises, have been adopting smart factory to increase their manufacturing efficiencies. However, Korean small and medium-sized enterprises (SMEs) have many financial and technological difficulties so that the diffusion of smart factory in Korean SMEs has not been satisfiable up to present. However, smart factory is very important for enhancing their competitiveness in global market. Therefore, this study aims at identifying the standardization strategy of smart factory in so-called Korean 'roots industry' by presuming that the standardization will activate the diffusion of smart factory among Korean SMEs. For this purpose, first, this study examines the competitiveness of SMEs, especially in 'roots industry' and identifies the necessity of diffusion of smart factory among those SMEs. Second, based on the active review on the existing literature, this study identifies four factor groups that would influence the adoption or diffusion of standardized smart factory. They are technological, organizational, industrial and policy factors. Third, using those four factors, this study made two comprehensive case analyses on the adoption and diffusion of smart factory. These two companies belong to molding sector which is one of the important six sectors in 'root industry'. Finally, based on the theoretical and empirical analyse, this study suggests four strategies for activating the standardization of smart factory; international standardization, government-leading standardization, firm-leading standardization, and non-standardization.
