Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.

The purpose of this study is to provide empirical findings about intragenerational and intergenerational discrepancies in eldercare attitude and behavior in Korea. Specifically, intragenerational discrepancies refer to phenomena in which eldercare attitude and behavior diverge from each other within the caregiving and care-receiving generations, respectively. Intergenerational discrepancies, on the other hand, refer to two kinds of phenomena, one in which eldercare attitudes are different between caregiver and care-receiver and the other in which eldercare behavior is differently recognized between the two parties. For the last couple decades, these kinds of discrepancies tended to be simply assumed without any coherent theoretical and/or empirical rationales. Thus, the current study tried to investigate the degree, pattern, and characteristics associated with the discrepancies. Analysis of data collected from 276 matched pairs of caregivers (i.e., daughters-in-law) and care-receivers (i.e., the elderly) in Kwangju and its suburb areas has indicated a substantial amount of both intra- and inter-generational discrepancies. In other words, both caregivers and care-receivers were found to be experiencing huge discrepancies between attitude and behavior in their respective generation: the factual discrepancies in attitude between the two generations were quite salient: the cognitive discrepancies in behavior between them were salient, too. In addition, it was also found' that the extent to which the discrepancies became salient differed for the three subdimensions of eldercare (i.e., emotional, economic, and physical care), and that such discrepancies have intimate relationships with a set of sociodemographic characteristics for caregivers - notably, age, educational attainment, area of residence, household income - on the one hand, and those for care-receivers - notably, gender, age, educational attainment, cohabitation, family size, inheritance, owned property - on the other. A series of theoretical, empirical, and clinical implications stemming from the findings were suggested and fully discussed in the context of Korean society.

본 논문에서는 60GHz WPAN (Wireless Personal Area Network) 시스템에서 릴레이를 이용한 협력 통신 기법을 제안하였다. 60GHz 대역은 LOS (Line-Of Sight)가 보장되어 있지 않은 경우 통신이 불가능하고 거리에 따른 신호 감쇄가 심하기 때문에 릴레이를 이용한 협력 통신 기법이 효과적이다. LOS가 존재하는 환경에서도 수신단이 송신단으로부터 받은 데이터뿐만 아니라 릴레이를 통해 데이터를 수신한다면 수신된 정보의 신뢰성을 높일 수 있다. 하지만 이 경우에 송신단이 데이터를 전송하는 시간뿐만 아니라 릴레이가 데이터를 전송하는 시간이 필요하기 때문에 정보의 전송률이 저하된다. 본 논문에서는 이러한 문제점을 해결하기 위하여 협력 통신 시스템에 적합한 Reed-Solomon(RS) code와 convolutional code(CC)의 직렬 연접 부호 구조를 이용하여 이러한 단점을 최소화 한다. 제안하는 협력 통신 기법은 릴레이에서 systematic RS code의 parity만을 convolutional code로 인코딩하여 전송하므로, 릴레이가 전송해야 하는 데이터의 양이 매우 적어 시스템의 전송 효율을 향상시킨다.

본 논문에서는 펄스 체이싱 스캔 방식을 이용한 바이스태틱 MTI 레이더 시스템에서 시스템 불안정 요인들을 식별하고 MTI 개선 성능에 미치는 영향에 대해 고찰하였다. 펄스 체이싱 스캔 방법은 송신 펄스 단위로 제한된 영역을 탐지하는 스캔 방법이며, MTI 필터는 작은 수의 펄스를 이용하여 클러터와 같은 간섭으로부터 표적을 분리할 수 있는 신호 처리 방법이다. 이상적인 MTI 신호 처리 과정은 클러터 자체의 특성에 의해서 클러터 감쇄 및 시스템 개선 성능이 제한되나, 제안된 바이스태틱 레이더 구조에서 MTI 성능은 펄스 체이싱 스캔 동안 수신빔 조향 오차에 의해 영향을 받을 수 있다. 또한, 바이스태틱 수신기에서 시간 동기 오차, COHO의 위상 오차 및 주파수/위상 동기 오차로부터 야기된 다른 시스템 불안정 요소들을 정의하고, 시스템 성능 개선에 미치는 영향들을 분석하였다.

Background : In this paper patient outcomes research is going to be reviewed and described, to be compared with relevant studies, and to consider the application in Korea. Methods : We compiled and reviewed the articles and materials related to patient outcomes research especially by PORT(Patient Outcomes Research Team) and rearranged them for seeking the main point and comparing with relevant studies. Results : Patient outcomes research emphasizes patient outcomes as well as conventional clinical outcomes. It is prospective study observing effectiveness in real situation instead of efficacy in ideal condition. Patient outcomes research comprises of 6 fields ; literature review and meta-analysis, use of claims data, decision modeling, outcomes assessment, cost of care, dissemination of research findings. SAA(small-area variations analysis), appropriateness study and clinical practice guideline are connected with patient outcomes research. Conclusion : In view of the fact that current medical policy in Korea is shifting its focus from accessibility to the improvement in quality and cost containment, and is stressing patient-based research, patient outcomes research is one direction for which the medicine is accountable and assessable. Considering that the number of patient receiving medical treatment in Korea is higher than the West, patient outcomes research has competitive power as against the West.
