Purpose: The purpose of the study is to explore the socio-psychological coping process and experiences of families before and after institutionalization by applying the Corbin and Strauss ground research method. Method: Data collection from 9 participants with elderly institutionalized dementia with approval from directors of the institute was done by in depth interviews during a seven month period from May, 2003 to December, 2003. Data analysis was done by repeated reading of the transcribed interviews, and 344 concepts and 39 subcategories were generated. Results: Family members of the dementia elderly experienced various degrees of exhaustion, physically, mentally, and socially. The degree of their exhaustion was related to the severity of the family member's symptoms, and length of the dementia. Coping strategies were effected by economic status, social support from blood related families or neighbors, depth of their relationship with elderly institutionalized dementia. They were even affected by the elderly family members institutionalization. Conclusion: After institutionalization participants felt some guilt from not assuming their responsibilities as children. On the other hand they regained privacy, freedom, security, and comfort, so that their life returned to normal. They even felt more comfort because their elderly were living in a safer environment, and received a better quality of care. Participants had better composure, so that they could even take care of neighbors in need. They hope that there is more governmental involvement in terms of subsidy and numbers of institutes. Findings of the study will be a ground for the development of a coping program for families with elderly institutionalized dementia. Further studies are recommended to explore types of family, and to develop programs for the families to help them interact with each other.

This study was conducted to analyze the reasons for aging in place through an in-depth interview, which is a qualitative research method. The subjects of the study were 17 adults over the age of 60 years who preferred aging in place. Interviewees were asked questions about their experiences of past living, present living, and the future place where they want to live in and the reasons for their choice. In the in-depth interviews conducted from September 2012 to May 2013 for data collection the research participants were asked open-ended questions about their past living experiences and future living plan and were given the freedom to answer the questions in their own words. The results of the in-depth interviews revealed the following reasons for aging in place: 1) familiarity due to long-term residence, 2) strong attachment to the place and the neighbors, 3) satisfaction of present house, 4) personal stories associated with present house, 5) feeling of living in their own home, 6) convenience of the neighborhood for living, 7) caring relationship with the neighbors, 8) fear of a change of environment, and 9) resignation to the rest of their life. The findings indicated that residential types in old age need to be taken into account for both aging in place which referring to choosing to live where one has lived for years and referring to involuntarily staying where one has lived for years.

오늘날 통신 기술이 나날이 발전하고 있지만 디지털 영상신호가 방대한 데이터를 가지고 있기 때문에 데이터의 저장, 처리 및 전송을 위해서는 보다 많은 데이터 압축이 필요하게 되었다. 이에 따라 ITU-T에서는 디지털 영상신호의 압축 표준을 위해서 H.26x 등을 제정하였다. 일반적으로 영상처리에서는 픽쳐간 상관 관계를 이용하여, 픽쳐간의 움직임 예측을 통한 시간적 중복성을 제거하여 데이터를 크게 압축하는 것이 많이 사용되고 있다. 대부분의 비디오 코팅 시스템에서 움직임 예측/보상(Motion Estimation/Compensation)방법으로 블록 정합 알고리즘을 사용하는데 이는 특정한 비용 함수의 최소 값을 기반으로 사용되고 있다. 그러나 이 방법은 많은 수의 계산을 필요로 하여 탐색 시간이 오래 걸리는 단점이 있다. 따라서 H.26x에서와 같은 실시간 저비트율 부호화를 위해서는 전역 탐색법 보다는 효율적인 고속 탐색 알고리즘이 효과적이다. 본 논문에서는 움직임 예측에 소요되는 탐색 시간을 줄이기 위해서 고속 탐색 알고리즘 중에서 Nearest-Neighbors 탐색 알고리즘을 이용하여 움직임 예측기를 FPGA로 설계하였으며, VHDL로 코딩(Coding)하고, Xilinx Foundation을 이용하여 설계 및 검증하였다.

영상 잡음의 제거를 위해서는 영상에 대한 통계적 모델을 설정하고, 잡음이 섞인 영상에서 원 영상의 분산을 정확하게 추정하는 것이 매우 중요하다. 분산을 추정하기 위해서는 일반적으로 유한한 크기의 주변 영역 정보를 이용한다. 주변 영역의 크기는 평탄 영역 및 에지 영역과 같이 영상의 영역에 따라 달라진다. 즉, 에지 영역인 경우는 주변 영역의 크기를 작게 설정할수록 추정 분산이 보다 정확하며, 평탄 영역의 경우는 주변 영역의 크기가 크면 분산의 추정이 정확해 진다. 이와 같이 추정된 원 영상의 분산을 이용하여 잡음 영상에 Wiener 필터를 적용함으로써 영상의 잡음을 제거하는 것이 일반적이다. 본 논문에서는 영상의 잡음을 제거하기 위해 웨이블릿 영역의 부모-자식 관계를 이용하여 중요도를 작성하고, 이를 이용하여 분산을 구하기 위한 이웃 영역의 범위를 결정하는 방법을 제안한다. 먼저 웨이블릿 계수의 중요한 특성을 획득할 수 있는 중요도를 작성하기 위해 간단한 분류 방법을 사용한다. 중요한 웨이블릿 계수의 수에 근거하여 웨이블릿 계수의 범위를 결정한 뒤 ML 방법을 이용하여 원 신호의 분산을 추정한다. 실험 결과를 통하여 제안 방법이 기존의 방법보다 나은 결과를 보여줌을 알 수 있다.

최근 유클리드 공간 상에서 효율적인 k-최근접(k-Nearest Neighbors) 질의 처리를 위해 그리드 구조 기반의 많은 색인 기법들이 연구되었다. 하지만 기존 기법들은 k-최근접 객체들을 연산하기 위해 불필요한 셀을 접근하여 연산 자원을 낭비하거나 근접한 셀을 알아내는데 매우 큰 연산 비용을 초래한다. 그래서 본 논문에서는 한 셀과 주변 셀과의 거리 관계를 나타내는 거리 관계 패턴을 이용하여 k-최근접 질의 처리시 적은 연산 비용과 적은 저장 공간을 사용하는 새로운 k-최근접 질의 처리 기법을 제안한다. 본 논문에서는 k-최근접 질의 처리의 대표적인 기법인 CPM과 성능을 비교하여 제안하는 기법의 우수성을 입증한다.

본 연구의 목적은 단독가구 노인의 가족관계가 지역사회참여에 영향을 미치는지 또한 이러한 관계는 성별에 따라 차이가 있는지 고찰하는 것이다. Baltes와 Baltes(1990)의 선택, 적정화, 보상 이론(SOC)과 Prandini(2014)의 가족구성원이 사회적 자본이 된다는 주장을 바탕으로 노년기에 가족관계가 지역사회참여에 영향을 미칠 수 있는지 검증하였다. 이를 위하여 본 연구에서는 한국보건사회연구원에서 실시한 2017년 노인실태조사에서 1인가구를 추출해 연구대상자(남 n=370, 여 n=1770)로 삼았으며, 친구·이웃만남과 경로당·복지관 참여를 종속변수로 다중회귀분석을 실시하였다. 연구결과는 다음과 같다. 남성의 경우 가족관계가 친구·이웃 또는 경로당·복지관 참여에 유의미한 영향을 보이지 않았으나, 여성의 경우는 가족과의 연락빈도가 친구·이웃만남에 정적(+)인 영향을 보였으며, 경로당 복지관 참여에는 가족연락빈도와 자녀관계 만족도가 정적(+) 영향이 나타난 반면 가족만남빈도는 경로당 복지관 참여에 부적(-) 영향이 나타났다. 여성의 경우 가족구성원이 사회적 자본이 된다는 Prandini(2014)의 주장이 지지되는 것으로 보이나, 어떠한 종류의 지역사회참여인가에 따라서 그 영향이 다를 수 있음을 확인하였다. 아울러 이에 대한 실천적 논의와 제언이 제시되었다.

Purpose: The purpose of this study was to investigate the subjectivity of undergraduate students about happiness. Methods: Q methodology, which scientifically measures individual subjectivity, was used. Thirty-four Q-statements selected from 40 participants were classified into a shape of normal distribution using a nine-point scale. The collected data were analyzed using a PQMethod PC program. Results: Type I: Self-directed, growth-seeking type. This group of people searches for their objectives and direction in life while consistently making efforts to realize their goals. Type II: Oriental and wealth-seeking type. This group of people sympathizes with the oriental worldview and believes in having luck such as wealth or health. Type III: Realistic and pleasure-seeking type. This group of people tries to think positively but while rooted in reality, searches for pleasure and satisfaction in their surroundings. Type IV: Altruistic and relationship-seeking type. This group of people stresses the importance of religious life, small happiness in life, and relationship with friends or neighbors. Conclusion: The results of this study provide the foundation for understanding college students' perception about their happiness. Furthermore, these results suggest the necessity of specific and integrated education to improve happiness.

LLAH(Locally Likely Arrangement Hashing) is a method which describes image features by exploiting the geometric relationship between their neighbors. Inherently, it is more robust to large view change and poor scene texture than conventional texture-based feature description methods. However, LLAH strongly requires that image features should be detected with high repeatability. The problem is that such requirement is difficult to satisfy in real applications. To alleviate the problem, this paper proposes a method that improves the matching rate of LLAH by exploiting together the brightness of features. Then, it is verified that the matching rate is increased by about 5% in experiments with synthetic images in the presence of Gaussian noise.

This study researches the level of satisfaction by apartment building management factor for different characteristics of apartment building residents and seeks to understand the relationship between socio-psychological properties and level of satisfaction. This study is based on a comparative method using a questionnaire by more than 682 housewives living in apartment complexes. Residents of apartment buildings are generally satisfied with housing and management of the apartment building that they are currently living in, but they wanted improvements such as programs that can support community living and increase participation of residents and operation of a web site. Furthermore, it was found that there was a significant difference in terms of operation management, such as sanitation control and processing for apartment buildings and community life management, according to the characteristics of the resident. Also, level of satisfaction in management was found to be influenced by pride and level of satisfaction in relationships with neighbors, showing that management of apartment buildings can have a positive impact on the socio-psychological properties of the residents.
