  • Security support is a significant factor in ad hoc networks. Especially in dynamic topologies, key agreement with private key updating is essential in providing a secure system. And it is also necessary to protect the identities of individual nodes in wireless environments to avoid personal privacy problems. However, many of the existing key agreement schemes for ad hoc networks do not consider these issues concurrently. This paper proposes an anonymous ID-based private key update scheme and a key agreement scheme for mobile ad hoc networks. We also suggest a method of rekeying between different domains using service-coordinators. These schemes are secure against various attacks and are suitable for service-oriented mobile ad hoc networks.

  • Purpose: The purpose of this study was to examine job status and job satisfaction among clinical research coordinators. Method: Subjects were 91 clinical research coordinators participating in clinical trials at hospitals in Korea. Data were collected from July to August, 2008 using a structured questionnaire that include informed consent, and question as pertaining to, general characteristics, job related characteristics, and job satisfaction. The collected data were analyzed using SPSS 12.0 version. Result: Almost half of the subjects were called as nurse researcher. Major tasks included participant screening (100%), participant scheduling (100%), and obtaining informed consent from participants (98.9%). The most difficult aspect of work was salary (28.6%). The mean score on the job satisfaction was 80.21 (range: 54.00-109.00). Item related to promotion ranked lowest in job satisfaction. There were significant differences in job satisfaction according to the type of hospital (t=-3.640, p<.001), title (t=7.894, p=.001), and route for information of CRC (t=4.970, p=.001). Conclusions: Subjects feel poorly compensated, unrecognized, and perceive a limited career path. These factors are likely to diminish job satisfaction over time. Attention to these aspects through education program and criteria for clinical research coordinators could be helpful.

  • Recent advances in RNA biology reveal unexpected diversity and complexity of cellular RNA metabolism. RNA-binding proteins (RBPs) are essential players in RNA metabolism, regulating RNA splicing, transport, surveillance, decay and translation. Aberrant expression of RBPs affects many steps of RNA metabolism, significantly altering expression of RNA. Thus, altered expression and dysfuncting of RBPs are implicated in the development of various diseases including cancer. In this minireview, we briefly describe emerging roles of RBPs as a global coordinator of post-transcriptional steps and altered RBP as a global generator of cancer related RNA alternative splicing. Identification and characterization of the RNA-RBP network would expand the scope of cellular RNA metabolism and provide novel anti-cancer therapeutic targets based on cancer specific RNA-RBP interaction.

  • The system implemented in this paper partitions and stores specimen data captured by a light microscope on distributed or parallel systems. Users ran observe images on computers as we use a physical microscope. Based on the client-server computing model, the system consists of client, coordinator, and data manager. Three components communicate messages. For retrieving images, we implemented the client program with necessary functions for educational applications such at image mark and text annotation, and defined the communication protocol. We performed the experiment for introducing a tape storage which stores a large volume of data. The experiment results showed performance improvement by data partitioning and indexing technique.

  • This study is being conducted in order to confirm the effects of inhaling method for aromatherapy on cortisol which is a stress hormone by the saliva test method. An attempt is being made to dertermine if there are any differences between the effect of lavender and rosemary when concidering their effects on the cortisolsl. The test shows a statistically significant decrease in the cortisol levesl(Table 4), and as far as the comparison of the effects between lavender(N=10) and rosemary(N=10) is concerned, the lavender group show a p-value of .005 which means that there are no statistical significances; while the rosemary group show p-values of .081 meaning that there is a decrease in cortisol levels, which is statistically significant(Table 5). It has been proven that the saliva test method is a practical and scientific method when confirming the effects of aromatherapy and also a convenient method for both of the test coordinator and the subjects. Results of all 20 subjects showed similar results obtained by means of conventional blood tests. However, the rosemary group shows statistically significant decrease in cortisol level compared to the lavender group, thus proving that the test method for studying the effect of aromatherapy on stress is valid. Further studies should be conducted in order to investigate the differences in the effects of the cortisol level at different concentrations of the aroma.

  • Every medical school aims to provide better education, and it sometimes requires changing the current education system. However, an attempt for a change may not always be successful. In many cases, it is so not because an intended change was not properly directed but because conflicts in the process of adopting the change were not properly handled. This paper suggests seven points for how to successfully bring a change in medical education. First, the medical education should not simply focus on the pass rate of the national medical examination but also on the cultivation of creative leaders. Second, the faculty of medical school should be creative, self-motivated, and passionate. Third, people in charge of an intended change should have a good understanding of complicated dynamics between the dean's office, medical education experts, professors, and students. Fourth, people who are leading the change should also grasp the possibility that a well-intended change might not be well-received by professors, students, and dean due to their tendency to be complacent with the current system. Fifth, a successful introduction of a change requires good teamwork of a thinker, an actor, and a coordinator. Sixth, a change takes time as it takes place through a step-by-step process. Seventh, an attempt for a change accompanies a negotiation with professors with different thoughts and views regarding education, and people who want a change need to be flexible in that negotiation. In addition to these seven points, people who are responsible for a change should be consistent and consider the renown of the school.

  • Background: Policy network theory was proved to be an appropriate analytic tool for the current social welfare policy making process. This study aimed to analyze policy making process related to the nurse expansion and policy output while focusing on the interactions and activities among various policy actors. Methods: In this study, we used reports related to the need for expansion of nursing personnel journals, dissertations, newspaper articles, for hearings and debate policies for securing nurse data, and interviews. We examined three components of policy network, that is, policy actors, interactions, linkage of interest. Results: For that to expand the nurse before the 2000s in expanding the supply of medical supplies have been conducted without much disagreement among policy actors under the government's initiative. However, there was lacked a close relationship between the expanding supply of nurses and inaccurate analysis of supply and demand. As the policy is applied between the various policy actors' needs and claims, conflict was intensified and many policy options had been developed. Government only took a role as a coordinator among policy actors in the 2000's. Also, it was difficult to find sufficient and clear evidence that policy-making process based on fair judgment. Conclusion: Therefore, it is urgently required to determine the policy through a social consensus to address the appropriate policy means and the process by correct analysis of the policy issues.

  • Recently, the use of wireless body area networks (WBAN) has been increasing rapidly in medical healthcare applications. WBANs consist of smart nodes that can be used to sense and transmit vital data such as heart rate, temperature and ECG from a human body to a medical centre. WBANs depend on limited resources such as energy and bandwidth. In order to utilise these resources efficiently, a very well organized medium access control (MAC) protocol must be considered. In this paper, a new, adaptive and energy-efficient MAC protocol, entitled isMAC, is proposed for WBANs. The proposed MAC is based on multi-channel communication and aims to prolong the network lifetime by effectively employing (i) a collision prevention mechanism, (ii) a coordinator node (WCN) selection algorithm and (iii) a transmission power adjustment approach. The isMAC protocol has been developed and modelled, by using OPNET Modeler simulation software. It is based on a networking scenario that requires especially high data rates such as ECG, for performance evaluation purposes. Packet delay, network throughput and energy consumption have been chosen as performance metrics. The comparison between the simulation results of isMAC and classical IEEE 802.15.4 (ZigBee) protocol shows that isMAC significantly outperforms IEEE 802.15.4 in terms of packet delay, throughput and energy consumption.

  • 목적 : 뇌정위 방사선수술은 AVM(ateriovenous malformation)이나 작은 크기의 종양에 1회에 고선량의 방사선을 조사하는 기술이다. 선형가속기를 이용한 방사선 수술을 하기 위하여 최근 본원에 설치한 Philips SL 75-5 선형가속기와 isocentric sub system(ISS)에 의한 뇌정위 방사선 수술에 있어서 표적의 위치선정과, gantry와 couch의 회전시 기하학적 오차가 중요시 되는데 isocentric sub system의 오차를 분석 하였다. 대상 및 방법 : 방사선원으로는 Philips SL 75-5 선형가속기의 5MV 광자선을 사용하였고, 원형의 작은 광자선속을 위하여 isocenter에서의 직경이 26mm인 secondary cone을 gimbal baaring에 삽입하여 사용하였다. 표적의 크기와 좌표를 정하기 위하여 CT나 angio localizer를 이용하고, 표적좌표 선정을 위하여 BRW phantom base와 target pointer를 이용하여 임의의 BRW-coordinator를 바꾸어 가면서 gantry angle와 ISS head 각도를 임의로 바꾸어 가면서 film에 방사선을 조사하였다. 흑화된 film을 view box 위에 놓고 광학판독기구로 film 가장자리의 오차를 scale 확대경으로 측정하여 오차를 분석하였다. 결과 : 표적좌표 선정의 정확도를 확인하기 위하여 임의의 표적좌표에 gantry의 10개각도 ISShead의 10개각도에서 각각 광자선을 조사시켜 film을 이용하여 오차를 측정한 결과 collimator cone의 직경이 26mm일때 전체 평균오차가 0.219+-0.03mm이었다. 결론 : Isocentric sub system은 gantry head와 ISS arm 사이에 gimbal bearing이 있어서 이 부위를 flexible하게 연결함으로 gantry의 회전에 무관하게 정확한 isocenter를 유지시켜 주고 ISS head는 couch와 독립되어 움직이므로 isocentric sub system isocenter의 오차를 최대한 줄일수 있음을 알았다.
