현재 이동통신망에서 요구되는 많은 통신량을 수용하기 위해서 새로운 주파수 대역을 사용하는 5G New RAT(: Radio Access Technology) 에 대한 연구가 활발히 진행되고 있다. 하지만, 이러한 새로운 New RAT 기술이 이동통신에 적용되었을 때에 이를 유선 이동통신망에서 수용할 수 있을지에 대해서는 제대로 연구된 바가 없다. 따라서, 본 연구에서는 이러한 New RAT 기술을 RoF(: Radio over Fiber) 기술로 이동통신망의 Fronthaul에서 수용이 가능한지에 대한 연구를 진행하였다. 본 연구에서는 New RAT 의 기술로 밀리미터파 통신기술, 테라헤르츠파 통신기술, 무선 광통신 기술 등을 고려하고, 이들 각각에 대한 RoF 기술의 응용 가능성을 연구하였다. 연구의 결론을 요약하면, 10 년 이내의 범위에서 세 가지 New RAT 기술 중에 밀리미터파 통신기술에 대해서만 RoF 수용성을 고려하면 되는 것으로 판단되며, 빔포밍을 사용하는 경우에는 밀리미터파 통신기술의 요구 전송 대역폭이 너무 많아 Fronthaul 에서 RoF 기술로도 수용이 쉽지 않은 것으로 결론이 내려졌다.

In this paper, a new green clustering algorithm is proposed to be as a first approach in the framework of an energy efficient strategy for centralized enterprise high-density WLANs. Traditionally, in order to maintain the network coverage, all the APs within the WLAN have to be powered-on. Nevertheless, the new algorithm can power-off a large proportion of APs while the coverage is maintained as its always-on counterpart. The two main components of the new approach are the faster procedure based on K-means and the more accurate procedure based on Evolutionary Algorithm (EA), respectively. The two procedures are processes in parallel for different designed requirements and there is information interaction in between. In order to implement the new algorithm, EA is applied to handle the optimization of multiple objectives. Moreover, we adapt the method for selection and recombination, and then introduce a new operator for mutation. This paper also presents simulations in scenarios modeled with ray-tracing method and FDTD technique, and the results show that about 67% to 90% of energy consumption can be saved while it is able to maintain the original network coverage during periods when few users are online or the traffic load is low.

When an organization adopts new technology, performance through the technology is expected to be decided depending on attitudes of the members, in that technology produces performance only if the members zealously use it. Therefore, the members need to devote themselves to acquire and use the new technology. This attitude of members is called "IT acceptance will" (Ranarajan et al., 2005), and this research is to examine the effect of an individual's "IT acceptance will" on performance. Thus, this research analyzes what increases IT acceptance will and what effect IT acceptance will has on stress due to uncertainty of an organization-job complexity and role conflict- through new IT adoption. This research conducted a survey from July to September in 2009, targeting employees of government offices and public institutions in Kyunggi and Kyungnam provinces. Then, a total of 370 was collected and the final 344 was selected for our research analysis. As a result, this research found out that personal innovation and client orientation improved an individual's IT acceptance will, which improved performance through new IT adoption. However, the new IT adoption also increased job complexity and role conflict, but negative effects of stress on performance was not found as IT adoption will diminished the stress. Based on this result, this research discussed practical and academic implications and the limitations.

Digital technology has been changing everyday life of ordinary people let alone the structure of world industry. The elderly care service is also going through changes influenced by the unavoidable impact from torrents of digital technologies. There are numerous reports and news about the digital technologies increasing the efficiency and effectiveness of care service yet lacking systematic understanding of the sources of such improvement. This study aims to present a new classification framework for digital elderly care service innovation to fully utilize the power of digital technologies drawing on insights from innovation studies and service studies. First, 4 features of digital technologies are identified as sources of new value in service innovation. The co-creation of value by users and producers in service and technology development is discussed to illuminate users' contributions to service innovation. Communication of needs and ideas with producers and application of new technologies into everyday practice of life are identified as the source of new value which can be attributed to the elderly. Customization along with efficiency gains is the key to digital elderly care service innovation. The classification framework, thus, incorporates the needs of the elderly as one axis of criteria in the conventional technology-centered framework. The new classification framework would help give due weight to user-driven or demand-driven innovation in the elderly care service R&D activities.
