Recently, although many firms conduct open innovation through collaboration with other innovation actors, little attention has been paid to research and case study with regard to SMEs. However, since the capability of SMEs is too insufficient to access external resources and collaborate with other firms, SMEs have practical needs for active open innovation. In addition, although a lot of SMEs depend on external resources in terms of distribution, services and sales, most of open innovation-related research concentrate on R&D and production. Therefore, this research aims at presenting various types, methods and policy to stimulate the open innovation of SMEs. Typical types of open innovation which SMEs can take will be identified and then a relevant open innovation type will be matched on the basis of the characteristics of sectors. The results of this research will be helpful for policy makers to promote open innovation in SMEs.

KISTI(Korea Institute of Science & Technology Information) CCBB(Center for Computational Biology and Bioinformatics) Website has been providing bioinformatics contents(databases and analysis tools) services to construct IT-based bioinformatics infrastructure. It also carries out the services to support domestic bioinformatics R&D activity and to construct the infrastructure. But, these services are not actively available because this CCBB website is not wellknown to users. Therefore, we performed the user survey for the researchers who are studying in the field of biological science. The items of this survey consist of subjects on bioinformatics databases, analysis tools and BioInfoNet. After the user survey is rearranged and analyzed, the result of survey will be used to provide the good service to the users who are need of bioinformatics infrastructure such as databases and analysis tools etc.

Global navigation satellite system (GNSS) has a weakness of signal integrity caused by broadcasting type data transmitting direct to user from navigation satellite. Loss of GNSS signal integrity can make a catastrophic event in the operation of unmanned aerial system (UAS) because position decision is only depended on GNSS. So it is required to apply alternative method to reduce a risk and to guarantee a GNSS signal integrity for UAS operation. This paper addressed the reason of loosing GNSS signal integrity, the effectiveness of signal jamming/spoofing and GNSS application trend for UAS. Also suggested the flight safety enhancing method in case of GNSS signal jamming for UAS as technical and political approaches.

Although traditional single-hop cellular networks had been serving well in past years, they are no longer economically feasible in supporting high data-rate, multimedia services of $4^{th}$Generation (4G) communications due to the requirement of high transmission power By contrast, multi-hop cellular networks (MCN) are capable of dramatically saving the transmission power by overlaying the capability of ad hoc networking among mobile terminals on the cellular network infrastructure. To achieve this performance gain as well as enable 4G services, an efficient routing protocol needs to be designed for MCN. In this paper, we propose a reactive route discovery protocol for MCN that uses directional information to the base station in the route discovery process. Our analysis/simulation results have demonstrated that the proposed protocol significantly reduces flooding overheads. In addition, we consider issues for 4G services in MCN and applications of the proposed protocol.

Resolution 221 requests the ITU-R to conduct studies, as a matter of urgency, on the feasibility of utilizing HAPS system as a base station to provide IMT-2000 services. And HAPS base stations should not cause harmful interference to the cellular IMT-2000 services. To study on the interference between HAPS system and cellular system is divided into two cases. One is the interference into HAPS system from the cellular system and the other is the interference into the cellular system from HAPS system. Since the former case has been already studied[1]. this paper describes the interference the interference to the noise power ration(I/N) with various parameters, such as the transmitting power, the number of users per cell, maximum antenna gain and the multibeam cell radius of HAPS. With the proposed estimation, we can determine the optimum values of various parameters in HAPS IMT-2000 system.

NTIS(National Science & Technology Information Service) provides the information for domestic research projects. It in particular has several classification schemes to classify research projects and provide better retrieval and analysis services. It however is difficult to understand the characteristic of a research project clearly since only a classification in a classification scheme can be chosen about a research project. Moreover, the classification scheme covers the high-level classification for every research areas so that it cannot cover the area specialized to the oriental medicines. On the other hand, the classification schemes for oriental medicines have recently been studied in oriental medicine field. However, it also covers the high-level classification for oriental medicine so that it may not suit to a classification scheme for research projects. Therefore, in this paper we propose a classification scheme to understand clearly the characteristic of research projects in oriental medicine and use to use them to retrieval and analysis services.

In order to utilize the operational metadata retrieval system which is based on the semantic association between the research outcomes of the Korean Research Memory (KRM), the systematic integration of the metadata of the research outcomes with the term data registry (DR) was required. This study presents the ontology which can be used effectively to support the KRM. It includes the concept modeling of the knowledge structure of research outcomes, information retrieval service modeling that applies an analytical approach to researchers' needs in conjunction with the term DR, and also some technical and administrative suggestions for future system management.

Despite the important role of the transformational leadership and Creative Climate to achieve firms' sustainable competitive advantage, there has been limited empirical studies linking the transformational leadership and creative climate in employee's innovative performance. This study investigated the impact of transformational leadership on innovative performance based on employees of R&D department in IT services. This paper also investigated the mediating role of creative climate and moderating role of employee's innovative tendency in this relationship. Main findings of our empirical analysis are as follows. While the relationships between transformational leadership and innovative performance was positively associated, creative climate had positive effect on innovative performance. As expected, we also found that the creative climate had positively mediated the relationship between transformational leadership and innovative performance. Also, the innovative tendency has statistically significant moderating effect on this relationship. Based on the findings, we have suggested theoretical and practical implications while future research directions with limitations of the research are discussed.
