Purpose: The purpose of this phenomenological study was to understand the experiences in the transplantation coordinators' practice. Method: Data was collected through a tape-recorded in-depth interview from nine participants who were transplantation coordinators of their hospitals. It was analyzed using the phenomenological method proposed by Colaizzi(1978). Results: From significant statements, six categories of themes were integrated into the essential structure of the experiences of transplantation coordinators. Six categories of themes were 'continue to be professional during dash this way and rush that', 'burden due to persistent heavy work', 'the uniqueness in family care of the brain-dead patients', 'support of family and a professional group', 'worthiness and achievement of the patients' recovery', and 'establishment of self-confidence as a coordinator'. Conclusion: Although the transplantation coordinators played various roles, they had a conflict in role identity due to poor working environments. The results of this study suggested that development of an educational program, an increase in understanding for the coordinators' role, and institutional support for better working conditions are needed to get professional acknowledgement for transplantation coordinators.

In this work, the current limiting and recovery characteristics of a flux-lock type superconducting fault current limiter (SFCL) with series connection of two coils were effectively improved by adding a third winding into the conventional flux-lock type SFCL with series connection of two coils. To confirm the contribution of the third winding to the current limiting and recovery characteristics of this type of the SFCL, short-circuit testing was carried out with consideration of the third winding, and the effect of the third winding on the current limiting and recovery characteristics was examined by comparative analysis of the amplitude of the limited fault current and the power burden of the high-TC superconducting (HTSC) element comprising the SFCL. Through the analysis of both the limiting impedance and the operational current as the main design parameter of the SFCL, the improved current limiting and recovery characteristics of the flux-lock type SFCL using the third winding could be verified.

Outsourcing is procuring of outside resources, other than core resources for core competence, by a contract, from which a corporate can focus its core resources on core business. The outsourcing strategies of Korea tourist hotel business are in a rudimentary stage, which has been limited in simple work areas such as housekeeping services, room maid services, parking control services, security services, janitor services, laundry services, facility management, shuttle bus services, and sterilization services and their purposes are mainly to retrench a burden of employment or firm-fixed expenses. Therefore, the outsourcing strategies of Korea tourist hotel business have the following problems. First, their outsourcing has introduced only for the purpose of retrenching expenses. Second, it tends to deteriorate service quality, due to lack of pre-training. Third, it tends to concentrate their attentions only on simple repetition works. Fourth, their outsourcing is slow adjusted to the needs of business cultures. Outsourcing services in Korea tourist hotel business have never contributed to their basic concepts such as 1) maintenance or enhancement of core competences, 2) promotion of business efficiency through service quality improvement and expense retrenchment, and 3) achievement or enhancement of competitive advantage through enlarging their specialties, cultivating their market, learning new knowledge, and developing their asset. Therefore, this study is to insist on fife necessity of overcoming simple repetitive service outsourcing in tourist hotel business. In order to build a core competence and/or achieve a competitive advantage, the scopes of outsourcing services should be enlarged in Korea tourist hotel business.

Optimum design of water distribution network(WDN) in many times means just reducing redundancy. Given only a few situations are taken into consideration for such design, WDN deprived of inherited redundancy may not work properly in some unconsidered cases. Quantifying redundancy and incorporating it into the optimal design process will be a way of overcoming just reduction of redundancy. Expected shortage is developed as a reliability surrogate in WDN. It is an indicator of the frequency, duration and severity of failure. Using this surrogate, Expected Shortage Optimization Model (ESOM) is developed. ESOM is tested with an example network and results are analyzed and compared with those from other reliability models. The analysis results indicate that expected shortage is a quantitative surrogate measure, especially, good in comparing different designs and obtaining tradeoff between cost and. reliability. In addition, compared other models, ESOM is also proved useful in optimizing WDN with reliability and powerful in controlling reliability directly in the optimization process, even if computational burden is high. Future studies are suggested which focus on how to increase applicability and flexibility of ESOM.

잘 알려진 무선 센서 네트워크의 프로액티브 프로토콜인 Flooding과 SPIN은 싱크 노드의 요청 없이 감지한 데이터를 즉각적으로 전송한다. 그러나 이러한 전송방법은 그 데이터가 필요하지 않는 노드들에게까지 전송하기에 에너지 효율성 측면에서 비효율적이다. 본 논문에서는 이러한 단점을 극복하기 위해서 전체 노드 대신에 적절한 일부 노드들에게만 전송할 수 있는 세미프로액티브 프로토콜을 제안한다. 따라서 만일 싱크노드와 같은 어떠한 노드가 감지한 데이터를 필요로 할 경우 미리 설정한 몇 홉 이내에 그 데이터를 쉽게 얻을 수 있다. 시뮬레이션 결과는 잘 알려진 SPIN과 비교하여 노드의 에너지 효율성이 약 83%까지 높다는 것을 보여주었다.

The demand for virtual reality (VR) is rapidly increasing. Providing the immersive experience requires much operation and many data to transmit. For example, a 360-degree video (360 video) with at least 4K resolution is needed to offer an immersive experience to users. Moreover, the MPEG-I group defined three degrees of freedom plus (3DoF+), and it requires the transmission of multiview 360 videos simultaneoulsy. This could be a burden for the VR streaming system. Accordingly, in this work, a bitrate-saving method using projection conversion is introduced, along with experimental results for streaming 3DoF+ 360 video. The results show that projection conversion of 360 video with 360lib shows a Bjontegaard delta bitrate gain of as much as 11.4%.
