This study is an attempt to present basic data for efficient terminal care based on the study of the terminal care stress and terminal care performance of nurses who work in geriatric hospitals. A survey was conducted from August 4 to August 29, 2014, targeting the nurses working in geriatric hospitals in Seoul and Gyeong-gi Do. The respondents were 160 nurses who were experienced in caring dying patients in the end-of-life stage. Overall 160 questionnaires were returned, and 158 out of them were used for the data analysis of this study.
For this study, the stress level in terminal care was measured with the tool developed by Yeon Ok Lee(2004); the level of terminal care performance was determined with the measurement tool designed by Soon Ju Park(1996). The collected data were analyzed by utilizing SPSS 18.0 program. In addition, descriptive statistic analysis, t-test, One way ANOVA, Scheffe test, and Pearson's correlation coefficient were also used in data analysis.
The results of this study are summarized as follows:
1. The level of terminal care stress among respondents turned out to be an average of 3.82±0.44 on a scale of 1 to 5. When considering the sub-categories, the level of stress caused by heavy workload was 4.07±0.60, the highest, followed by the level of stress caused by conflicts between patient's terminal illness and the limitation of nursing care(3.97±0.64), and the level of stress caused by negative attitudes to death and dying among patients and their family(3.96±0.56).
2. The level of terminal care performance turned out to be an average of 2.52±0.41 on a scale of 1 to 4. By specific category, the level of terminal care performance in physical area was the highest with the score of 2.98±0.48. Following in order were psychological area with 2.77±0.45, and spiritual area with 1.80±0.63.
3. When considering the general characteristics of the respondents, this study statistically showed that the stress levels were significantly higher in those who had more clinical experiences(F=4.877, p=.009), higher positions at the hospital(t=2.297, p=.023), and less education on terminal care(t=0.007, p=.006).
4. Considering the general characteristics of respondents, the level of terminal care performance was meaningfully high in those who experienced bereavement while being married(F=3.390 p=.036), who have religion(t=2.017, p=.046), who are in higher position at the hospital(t=3.666, p=.014), and who have education on terminal care(t=2.163, p=.032).
5. There was no strong evidence that stress level in terminal care correlated with terminal care performance scale(r=0.099, p=0.218). However, among sub-categories in terminal care stress, conflicts between patient's terminal illness and the limitation of nursing care(r=0.167, p=0.036) and negative attitudes to death and dying among patients and their family(r=0.168, p=0.035) were significantly interrelated with the level of terminal care performance.
In conclusion, as a result of this study, it seems to be necessary that continuous education on efficient terminal care should be provided to the nurses in geriatric hospitals in order to fulfill patients' needs for spiritual care as well as physical care. For that purpose, it seems to be imperative to establish the standards for terminal care.

They had made the aesthetic effort to overcome the difficulties of unstable period. The era that they had lived in was 'the era of Independence and the Korean war'. They were well aware of the declining situation at the time as the leading intellectuals. Korea in 1930's and 1950's was confused by Foreign intervention. There was an anxious mind and affliction about the era in their criticism of poems and poetry. Oh, Jang-hwan and Park, In-hwan received the different evaluations in their poetry. In short, it is generally said for Oh, Jang-hwan' poetry to turn from decadence into critical realism. On the other hand, it is generally said for Park, In-hwan to turn from realist in early poems into modernist in the later. But their criticism of poems reveal that it is true poetry to evoke the echo over pain and anguish of their own era. First of all they have common consciousness in the phase of embodying the unstable position of poetic subject. The eyes of poetic subject is dispersive in their poetry. Those are not centripetal. Their poetry derive the sensibility of anxiety and the dissolution of consciousness from the fragmental eyes. It is very important at the point of representing 'Reality of the world'. And then the eyes of subject in their poetry gaze vulgar bodies. Vulgar body in their poetry show in prostitute, diseased bodies, an alcoholic and etc. Through it is exposed to curious feelings by vulgar bodies, we won't fall into fetishism. It is a possibility of negative poetry. The negative consciousness in Oh, Jang-hwan's and Park, In-hwan's poetry differs from decadent and nihilism. There are an casual potentiality to find out after the subject has extremely denied himself

본 논문에서는 WiMedia UWB MAC의 기본적인 동작 메커니즘과 자원 할당 프로토콜에 관한 연구를 한다. 그리고 자원의 부족현상이 발생하였을 경우 지연에 민감한 실시간 서비스를 보장해주는 알고리즘을 제안한다. 제안한 알고리즘은 지연에 민감한 정도에 따라 트래픽의 우선순위를 분류하고 사용 가능한 자원이 없는 상황에서 높은 우선순위의 트래픽을 갖는 단말이 자원을 확보함으로써 실시간 서비스의 전송을 보장해 준다. 또한 DSP를 적용하여 제안한 알고리즘으로 인해 특정 트래픽이 자원을 독점하는 것을 방지하고 각 트래픽의 최소한의 자원을 보장해주었다.
본 논문에서는 기존의 WiMedia UWB MAC과 제안한 알고리즘이 적용된 MAC간의 성능을 비교 분석하였다. 성능분석 지표로는 처리율, 지연, 공정성 그리고 패킷 손실률이 있다. 분석 결과에 의하면 제안한 알고리즘은 자원이 부족한 상황에서 실시간 트래픽의 전송을 보장해주었고 실시간 트래픽에 대해 공정성을 보장하였다. 또한 단말의 수가 증가할 수록 제안한 알고리즘이 보다 향상된 성능을 나타내는 것을 확인하였다.제1장 서론 = 1

Abstract = 38MasterWiMedia UWB system is a distributed network where there is no central coordinator and can support high data rate. Since there is not a central coordinator which controls and manages resources among devices, it is important to utilize wireless resource efficiently. Though efficient resource allocation algorithms are defined in standard, algorithms that can overcome the problem where there lacks the resources are not yet proposed.
In this paper, basic mechanisms of WiMedia UWB MAC protocol and resource allocation schemes are studied. Moreover, the algorithm that guarantees delay-sensitive traffic is proposed when resource is insufficient. The proposed algorithm classifies traffic priority according to delay sensitivity and guarantees real-time traffic transmission by providing resources in case of resource insufficiency. In addition, we applied DSP to prevent a particular traffic from possessing resources exclusively due to our proposed algorithm and to provide minimum required resources to each traffic.
We analyzed and compared the performance of legacy WiMedia UWB MAC with that of the proposed algorithm. The performance metrics are throughput, delay, fairness and packet loss. As a result of the analysis, the proposed algorithm provides transmission and fairness of real-time traffic when resource is insufficient. Also as the number of devices increases, it is seen that the performance of the proposed algorithm is much improved
Statistical novelty detection within the Yeongjong suspension bridge under environmental and operational variations
Structural health monitoring is concerned with estimating the current health state of a structure being monitored and aims to provide reliable information on the presence, location, and severity of damage. When the structure experiences damage, it causes changes in structural parameters such as stiffness reduction and consequently alters measured signals or features extracted from the measured signals. Therefore, damage diagnosis can often be performed by novelty detection, i.e., detecting the changes in the measured signals or the features by comparing the most recent data obtained from an unknown condition of the structure with the baseline data accumulated from its normal conditions. In reality, time-varying environmental and operational conditions such as temperature, wind, and traffic loading also induce changes in the measured signals or the features and consequently may produce false alarms. Therefore, to achieve successful novelty detection, it is necessary to distinguish the signal changes caused by abnormality from those caused by environmental and operational variations. This process is called data normalization. In this study, kernel principal component analysis is employed to perform data normalization and incorporated with a novelty index and generalized extreme value statistics for novelty detection. The proposed approach is applied to the field data obtained from the Yeongjong grand bridge in Korea and demonstrated to be a promising tool for detecting abnormality in the presence of environmental and operational variations.The authors express gratitude to New Airport Hiway Co.

A Novel Predictive Current Control of Induction Motor Using Resonant DC Link Inverter
A predictive current control technique for an induction motor employing a resonant DC link inverter is proposed to overcome the disadvantage of the current regulated delta modulation (CRDM) which was employed to control the resonant DC link inverter. The discrete model of an induction motor and estimation of back EMF are investigated and a novel predictive current control technique is newly developed based on this discrete model and estimated back EMF. Using the proposed control technique, the minimized current ripple with reduced offset can be obtained. The usefulness of the proposed technique is verified through the computer simulation

Dehydrogenation reaction kinetics of the LiBH4-YH3 composite promoted by various inert gas atmospheres
The application of back pressure using inert gases, such as helium, neon and argon, significantly influences the dehydrogenation reaction kinetics of the LiBH4-YH3 composite, even though the inert gases do not participate in the dehydrogenation reaction. While an increase in back pressure generally promotes the reaction kinetics, the ability to promote dehydrogenation reaction kinetics differs for different the gas species. The atomic weight of the inert gas appears to play an important role in determining the ability to promote dehydrogenation reaction kinetics. With increasing atomic weight of the inert gas, the reaction tends to occur at lower pressures with a shorter incubation period.N
