  • It is difficult to support QoS service in existing MAC Protocols in Wireless Mesh Network environments. while DCF can not support QoS, EDCA is operated with prioritized channel access method but can not give full performance. This thesis proposes frame management method to support QoS in Multi-Media DCF(MMDCF) MAC Protocol working in wireless mesh network. MMDCF uses ACH phase in TDMA frame to perform selection and elimination. Prioritized phases's count m and Fair Elimination phases's count n determine contention level and make string probability to only one win the contention. Forced TDMA Frame release method can support QoS requirements. MMDCF results good performance and good channel efficiency to support QoS requirements better than EDCA in multimedia stream environments.

  • Purpose: This study examined how the degrees of muscle activity of Rectus Femoris and Tibialis Anterior during the four phases of walking vary according to three different treadmill slopes of $0^0$, $7^0$, and $15^0$. Methods: Subjects were 14 randomly selected healthy students attending G University in Seoul, Korea who had never had articular problems with lower limb and had no difficulties walking at the time of study. Results: 1) With respect to Rectus Femoris, in every phase of both forward and backward walking, there were significant differences among all of the slope degrees (p <.05), while the activity increased with increased slope degrees in every phase of backward walking. 2) For Tibialis Anterior, only in P2 and P3 of both forward and backward walking there were significant differences in every slope (p <.05). Conclusion: Both Rectus Femoris and Tibialis Anterior were found to be more active during backward walking compared to backward walking. In addition, the activity degree of Rectus Femoris was high between the early part of two foot support phase and the early part of one foot support phase, whereas that of Tibialis Anterior was high between the early part of one foot support phase and the latter part of both foot support phase.

  • The supported and unsupported boehmite ($\gamma$-AlOOH) membranes were prepared using a boehmite sol. The supported membrane was consisted of a porcelain support, two intermediate $\alpha-{Al_2}{O_3}$ layers, and a top boehmite membrane. XRD patterns showed that the supported top membrane had a higher $\theta-$ to $\alpha-{Al_2}{O_3}$ transformation temperature compared to the unsupported membrane. This result was also confirmed from microstructural study of the membrane. The shift in the phase transformation temperature should be explained by difference of a stress generated in the supported top membrane due to interaction between the support layers and the top membrane.

  • This study examines how the government's fairness in entrepreneurship support affects satisfaction and management performance, and examines whether these influences are different for each growth stage of start-up companies. For this study, data were collected for start-up companies that received government support for start-up within the past 5 years. Total 611 copies of the data were used in this study. The collected data were analyzed using SPSS and AMOS. The fairness used in this study was divided into three types, procedural fairness, interactive fairness, and distributed fairness. The effect of the three fairness on the satisfaction of start-up support project was analyzed. In addition, the effect of business support satisfaction on business performance was analyzed, where the business performance was evaluated by the questioner's satisfaction with their business. The start-up phase was divided into the start phase, early growth phase, stagnant phase, and high-level growth phase, and the moderating effect between the fairness and satisfaction of the government-supported projects by start-up phase was analyzed. As a result, it was found that every concept of fairness had a positive (+) effect on the satisfaction of the entrepreneurship support project, and the satisfaction of the entrepreneurship support project had a positive (+) effect on the management performance. The concept of procedural fairness in the start phase, procedural fairness in the early growth phase, interactive fairness, and the concept of all fairness in the stagnant phase influenced the satisfaction of the start-up support project. In this study, the fairness and effect of government-supported projects affecting the management performance of start-ups were identified by growth phase of start-ups. The results of these studies will help build a systematic system for entrepreneurship support and for start-ups, it will also greatly contribute to finding differentiated growth plans by growth stages of start-up companies.

  • Purpose: The purpose of this study was to evaluate the effects of Doula support during labor on anxiety, labor pain, and perceived childbirth experience of primiparas. Method: Of 65 primiparas who were hospitalized in LDR from March 1 to September 30, 2007. 32 women were placed in the Doula group and 33 in the control group. VAS was used to measure the degree of labor pain and anxiety in the latent, active, and transitional phases. Perceived childbirth experience was measured within 2 hours after birth. Results: The Doula group had a significantly lower anxiety level than the control group in the active phase (t=-2.13, p=.04) and the transitional phase (t=-3.99, p=.000). The degree of labor pain of the Doula group was significantly lower than that of the control group for the active phase (t=-3.10, p=.003) and the transitional phase (t=-7.24, p=.000). Also, There was no significant difference in perceived childbirth experience between the two groups (t=.19, p=.85). Conclusion: The results of this study show Doula support in LDR decreases not only anxiety of primiparas but also labor pain in the active and transitional phases. Therefore Doula support by nurses in LDR can be a useful intervention during childbirth.

  • In order to maintain construction industry and to improve efficiency, the Korean government legislated private investment system. Private sector takes advantages by adopting CM (Construction Management) project system, however, public sector has relatively less capability and experience than private sector. In this paper, PSM (Partnership Support Management) is addressed in order to actively strengthen the project capabilities for public sector. PSM maintains existing CM project system because it is a concept of expended business model of CM. PSM needed to categorize the private participated project into 5 phases; project development phase, project announcement phase, project evaluation phase, project agreement phase and agreement changing phase. PSM business structure and business process considering stakeholder's interrelationship and participation are suggested in this research. Suggested PSM business model may not only increase a comprehensive understanding of government and project capability, but also may reduce work load and responsibilities for project momentum of private participation in infrastructure.

  • This study was conducted to determine the effects of repetitive transcranial magnetic stimulation (rTMS) integrated mirror therapy on the gait of post-stroke patients. Thirty patients who were six months post-stroke were assigned to either the experimental group (n = 15) or the control group (n = 15). Stroke patients in the experimental group underwent rTMS and mirror therapy for the lower limbs, while those in the control group underwent rTMS and sham therapy. Participants in both groups received therapy five days per week for four weeks. A significant difference in post-training gains for the single support phase, step length, stride length and velocity was observed between the experimental group and the control group (p < 0.05). The experimental group showed a significant increment in the single support phase, step length, stride length, swing phase, velocity, cadence, double support phase and step width as compared to pre-intervention (p < 0.05). The control group showed a significant increment in step length, velocity, cadence and step width compared to preintervention (p < 0.05). Further investigation of the availability and feasibility of rTMS integrated mirror therapy for post-stroke patients as a therapeutic approach for gait rehabilitation is warranted.
