        Optical flow field 분할을 위한 2$\frac{1}{2}$D 및 정방형 모델과 결합된 버텀-업 피라미드 링킹 방법에 관 한 연구

        김춘길,이형재 한국통신학회 1991 韓國通信學會論文誌 Vol.16 No.11

        Optical flow는 물체의 속도 결정과 추적 뿐만 아니라 영상분할과 물체의 3차원 정보로서도 중요하다. 본 논문에서는 OFF(optical flow field)의 해석 즉, OFF 분할을 위하여 3가지 모델과 결합된 피라미드 랭킹방법의 분할 알고리즘을 제시하였다. 제시된 방법에서 각 노드는 노드가 지배하는 영역내의 flow field의 모델을 형성하고, 이 영역들은 최적 적합되는 모델을 취함으로서 상위 레벨상의 노드와 결합되어진다. 또한 각 노드는 노드가 지배하는 화소들과 부모화소의 folw field 모델 사이에서 발생하는 최소제곱오차를 기초로 하여 부모화소와 링크된다. 이와 같은 방법에 의해 기존 방법들에서의 주된 문제점인 잡음에 대한 민감성을 개선할 수 있었고, 이를 실험을 통하여 입증하였다. Optical flow is important not only for determining velocity and trajectory of the object but also for image segmentation and three dimensional information. In this paper an algorithm for segmentation of the optical flow field is presented. This method is based on a pyramid linking method combined with the proposed models. In this method each node contained a model of the flow in the region that it represented regions were combined by taking the model that best fit the union of the two regions. Each node linked to one of its fathers based on the error between the pixels represented by the node and the father's model of its flow. A major problem which has emerged in conventional researchs on optical flow field is sensitive to noise the proposed method is relatively insensitive to noise at the result of computer simulation the pyramid algorithm proposed in this paper seem to have useful properties.

        Purpose: This study was done to identify the relationship between family support, health perception, nutritional status and depression in elderly people. Method: The participants were 290 elders over 60 years of age who had visited Y city Senior Welfare Center from July 2006 to October 2006. Data were collected by questionnaire survey using convenience sampling. The instruments were Kang's Family Support Scale, Laffery's Health Concept Scale, Nutrition Risk Index by Nutritional Screening Initiative, and Depression Scale by Sheikh & Yesavage. Descriptive statistics and Pearson correlation coefficients were used to analyze the data. SPSS Win 12.0 program was used. Results: The depression level showed a maximum score of 15 with a mean score of 5.52; The mean score for family support, health perception, and nutritional status were 43.52(maximum score 55), 78.04(maximum score 112), 5.03(maximum score 21) respectively. There was a low negative correlation between family support and depression (r=-.272), and a low negative correlation support, Health perception, between health perception and depression Nutrition (r=-.330). There was a low positive correlation between nutritional status and depression (r=.429). Conclusion: These results suggest that low levels of family support, health perception, and nutritional status can result in increased levels of depression for older people. These findings should be considered in nursing care for elders focused on treating or preventing depression.

        국내 간호학회지의 노인논문 분석

        김춘길 노인간호학회 2005 노인간호학회지 Vol.7 No.2

        Purpose: This study attempted to analyze the trends in various kinds of research and to suggest future directions for gerontological nursing research in Korea. Methods: A total of 246 articles published in Korea from 1999 to 2004 were analyzed in this study focusing on the design of the research, the theoretical framework, key words, and the influencing variables in the case of experimental and correlational studies. Results: The most frequent research design used was quantitative design(76.8%). The majority of subjects were the elderly over 60 living at home. Only 10.6% of the investigators(n=246) identified a theory or conceptual model. Major concepts studied were mental and physical health. Among 46 experimental studies, the most frequent nursing interventions were rhythmic and exercise program. In 71 correlation studies, variables such as health promotion behavior, depression and family burden were found to correlate with nursing concepts. Conclusion: The number of studies has increased since the year 2000 but there have been not many studies using meta-analysis, triangular method, polices and suggestions of practical alternatives. Thus it is necessary to carry out more research in these areas.

        중년여성의 사별 스트레스와 우울과의 관계에서 스트레스 대처의 효과

        김춘길,이지원 한국통합사례관리학회 2019 한국케어매니지먼트연구 Vol.0 No.31

        The purpose of this study was to investigate the moderating effect of stress coping on bereavement stress and depression in middle - aged women and to provide basic data for intervention such as educational plan to improve bereavement stress management. For this purpose, 301 middle - aged women between 40 to 64 years who experienced bereavement of husband, parents, children, brothers and sisters living in S, I, and C city and G Province were surveyed. The results of the study showed that middle - aged women with bereaved experience had bereavement stress and depression, and depression was actively reduced by stress coping. Therefore, it is possible to contribute to improvement of quality of life by developing individualized care strategies for effective bereavement family management and by providing professional bereavement stress management in cooperation with relevant agencies in the community. However, since this study was a survey of the single - viewpoint, it is necessary to design more and more for researches in the future. 본 연구는 중년여성의 사별스트레스와 우울과의 관계에서 스트레스 대처의 조절효과를 알아보고 사별스트레스 관리 향상을 위한 교육 방안 등 중재에 기초자료를 마련하는데 연구의 목적을 두고 있다. 이를 위해 S시, I시, C시 및 G도에 거주하는 남편, 부모, 자녀, 형제의 사별을 경험한 40세∼64세의 중년여성 301명을 대상으로 자기기입식 설문조사를 실시하였다. 연구 결과 사별경험이 있는 중년여성은 사별스트레스와 우울감이 있었으며, 적극적인 스트레스 대처로 우울감이 감소함을 알 수 있었다. 이에 효과적 사별가족 관리를 위한 대상별 사별 돌봄 전략을 개발하고 지역사회에서 연계기관과 협력하여 전문적 사별스트레스 관리를 제공함으로 그들의 삶의 질 향상에 기여 할 수 있을 것이다. 그러나 본 연구는 횡단적 단일시점의 조사연구이었으므로 이후 연구에서는 보다 다양한 설계와 종단적인 연구가 필요하다고 본다.

        재가노인의 좋은 죽음에 대한 인지도와 가족지지의 영향

        김춘길,Kim, Chun-Gill 한국호스피스완화의료학회 2014 한국호스피스.완화의료학회지 Vol.17 No.3

        목적: 노년기는 죽음이 가까워지는 시기이고 노인들은 좋은 죽음을 원하지만 아직까지 노인에서 좋은 죽음의 정도와 영향요인을 규명하는 연구 자료가 부족하다. 이에 따라 본 연구에서는 재가노인을 대상으로 좋은 죽음의 인지도를 알아보고 그의 영향요인을 일반적 특성과 가족지지를 중심으로 살펴보았다. 방법: 대상자는 서울시, 경기도, 강원도 및 전라도의 지역사회 거주 노인들 중 편의 표출하여 연구에 참여를 서면 동의한 65세 이상의 노인 317명이었다. 구조화된 설문지 문항에는 일반적 특성, 좋은 죽음 19문항과 가족지지 11문항을 포함시켰으며 설문내용에 대해 대상자 스스로 기입하거나 자기기입이 어려운 노인은 연구자나 연구보조원이 설문에 대한 노인의 응답을 기입하는 방법으로 자료수집을 하였다. 자료분석은 기술통계, t 혹은 F 검정, 피어슨 상관계수 및 단계적 다중회귀 분석을 이용하였다. 결과: 좋은 죽음의 정도는 상으로 높은 편이었고 좋은 죽음의 요인 중 통제감이 가장 높았으며 문항별 정도는 '평화롭게 죽는 것이다'와 '죽음을 수용하는 것이다'에 이어서 '다른 사람에게 부담(폐)을 주지 않는 것이다'를 높게 인지하였다. 좋은 죽음의 인지도는 성별, 결혼상태와 경제상태에 따라 유의한 차이가 있었고 가족지지와 유의한 정적 상관관계를 보였다. 좋은 죽음에 대한 영향요인은 가족지지와 성별로 그 설명력은 10.2%이었다. 결론: 재가노인의 좋은 죽음을 위해서는 그들의 일반적 특성 중 성별, 결혼상태와 경제상태를 고려하고 중재가 가능한 가족 지지를 높여야 할 것이다. 또한 노인의 통제감을 높일 수 있는 방안을 모색하고 문항 중 높은 인지도를 나타낸 평화로운 죽음과 죽음 수용 등에 대해 초점을 맞추어 중재를 하여야 할 것이다. 나아가 본 연구결과를 기반으로 노인의 성별과 가족지지를 고려하여 그들의 좋은 죽음뿐 아니라 삶의 질이 유지, 증진될 수 있도록 지지 프로그램이나 정책 제안 등 합당한 노력을 강구하여야 할 것이다. Purpose: This study was conducted to investigate perception of good death among the community-dwelling elderly and identify factors related to the perception. Methods: A questionnaire survey was carried out using a convenient sampling method (N=317). Data were analyzed by applying descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and stepwise multiple regression. Results: Participants scored an average of 3.35 on a 4-point scale for the perception level of good death. They scored higher on the factor of personal control that other factors affecting the perception. Good death was positively correlated with family support (r=0.252). Family support (${\beta}$=0.287) and gender (${\beta}$=0.197) significantly influenced the elderly's perception of good death. These variables accounted for 10.2% of the total variance. Conclusion: The results show that family support is an important factor for the perception of good death among the elderly. Therefore, family support should be carefully considered to ensure good death for more senior citizens. Our findings can be utilized to support programs such as death education for the elderly.

        일 지역 재가노인의 일상생활수행능력과 자가간호역량 간의 관계

        김춘길,장희정,김성실 성인간호학회 2001 성인간호학회지 Vol.13 No.1

        The ratio of the elderly population is rapidly growing due to socio-economic development and better medical services. As the average life-span of the Korean elderly becomes longer, the proportion of the elderly is increasing. Therefore, the elderly need to sustain a high quality of life. However. all these factors, such as sensory loss, decreased endurance, mobility limitation, and a loss of independence, act to diminish the quality of life among the elderly. It is necessary for elders to adapt themselves to acting, to maintain their physical functions and especially, it is important to keep their independence in activity of daily living and self care. Therefore, this study was designed to identify the degree of activity in daily living and exercise of a self-care agency and to investigate the relationship between activity of daily living and self-care agency. Also, this research aimed to contribute to nursing interventions that maintain and promote quality of life of the elderly and to enable themselves to live independently. The subject of this study were 160 elders, over age 65, who were sampled in C city. Data were collected by observation and Questionnaires from May,1999 to December, 1999. The measurement tools were Barthel Index(1979) Lawton & Brody(1969) for activity of daily living and Kearney & Fleischer(1979) for self-care agency. Data were analyzed by SAS PC + package and included descriptive analysis, t-test, ANOVA. Pearson correlation coefficient, and Cronbach's alpha. The conclusions of this study are summarized as follows ; 1.The mean of ADL and IADL was 96.09 and 16.38, respectively. The score described activity of daily living among the elders in C province as moderate. Particularly, in the items of IADL, the item of medication was the highest score. 2.The mean for exercise of self-care agency was 76.48, a moderate degree. 3.The degree of ADL and IADL according to demographic characteristics was significantly different statistically in pocket money, the presence of disease, perceived health status and in occupation, pocket money, family type. the presence of disease, and perceived health status, respectively. 4.The dagree of self-care agency according to demographic characteristics was significantly different statistically in gender. education level, economic status, and pocket money. 5.There was a significant positive correlation between activity in daily living and self-care agency. Based on these results, further research is suggested to discover the variables influencing the activity of daily living and self-care agency to develop nursing strategies for improving self-care and activity of daily living among the elderly.

        Purpose: The purpose of this study was to investigate demented elderly caring competences of the formal caregivers(FCs) and to identify the influencing factors of the caring competence. Methods: A developed questionnaire survey was carried out using a convenient sampling method (N=201). Data were analyzed by applying descriptive statistics, t-test, ANOVA, Duncan test, Pearson’s correlation coefficient, and stepwise multiple regression. Results: The average score for the perceived FCs’ caring competences was 3.63 (SD=0.6). Among the FCs’ caring competency factors, care for elders with dementia(knowledge, attitudes, and skills) was the highest. Also the competences were positively correlated with job satisfaction, work experience, and numbers of participation in dementia education. Job satisfaction(ß=.30, p<.001), gender(ß=.19 p=.006), working place(ß=-.16 p=.020), and burden of caring dependency(ß=.16 p=.022) significantly influenced the perceived FCs’ caring competences. Conclusion: The study found that job satisfaction was an important factor for FCs’ caring competences, therefore FCs’ work loads should be carefully assigned to increase their job satisfaction. This research findings can be utilized for the management of FCs working in institutions for elders with dementia.
