본 연구는 장기요양시설 노인의 삶의 질에 관련된 요인을 알아보기 위하여 조사대상자의 인구사회학적 특성, 건강관련행위특성, 구강건강영향지수(OHIP-14), 신체적 기능(ADL, IADL) 및 정신적 기능(CES-D, MMSE-K)과 삶의 질(WHOQOL-BREF)과의 관련성을 분석하였다. 조사대상은 장기요양인정자로 판정받은 장기요양시설급여노인 602명으로 하였으며, 2016년 5월 1일부터 6월 30일까지의 기간 동안에 구조화된 설문지를 이용한 직접 면접조사와 구강검사를 실시하였다. 연구결과, 조사대상자의 삶의 질은 남성보다 여성에서, 생활비조달을 본인이 하는 경우보다 자녀가 조달하거나 정부의 보조를 받는다는 군에서, 요양기간이 길수록, 비음주군보다 음주군에서, 규칙적인 운동을 한다는 군보다 하지 않는다는 군에서, 식사를 규칙적으로 한다는 군보다 하지 않는다는 군에서, 주관적인 건강상태가 건강하다는 군보다 건강하지 않다는 군에서, 1일 칫솔질 횟수가 적을수록, 구강건조증이 없다는 군보다 있다는 군에서, 구강건강영향지수(OHIP-14)가 낮을수록, 신체적 기능(ADL, IADL)이 낮을수록, 정신적 기능(CES-D, MMSE-K)이 낮을수록 유의하게 낮았다. 특히 삶의 질은 다른 요인보다 건강관련행위특성과 정신적 기능(CES-D, MMSE-K)에 의해 더 큰 영향을 받고 있는 것으로 나타났다. 따라서 장기요양시설 노인의 삶의 질을 증진시키기 위해서는 바람직한 건강관련행위를 비롯하여 우울 및 인지기능장해를 예방하기 위한 노력이 필요할 것으로 생각된다.

본 연구는 장기요양시설 노인의 신체적 기능(ADL, IADL), 정신적 기능(CES-D, MMSE-K) 및 구강건강영향지수(OHIP-14)가 삶의 질(WHOQOL-BREF)에 미치는 영향을 알아보고자 시도하였다. 조사대상은 장기요양시설에 입소하여 있는 노인 602명으로 하였으며, 조사는 2014년 5월 1일부터 6월 30일까지의 기간 동안에 구조화된 설문지를 이용한 면접조사를 실시하였다. 연구결과, 조사대상자의 정신적 기능(CES-D, MMSE-K)은 신체적 기능(ADL, IADL)이나 구강건강영향지수(OHIP-14)보다 삶의 질에 더 큰 영향을 미쳤으며, 신체적 기능과 구강건강영향지수가 높을수록, 정신적 기능이 높을수록 삶의 질을 증가시키는 효과가 있는 것으로 나타났다. 위와 같은 연구결과를 볼 때, 장기요양시설 노인들의 삶의 질은 신체적 기능, 정신적 기능 및 구강건강영향지수와 유의한 관련성이 있음을 시사하고 있다.

The purpose of this study was to examine the effects of stroke patients' cognitive score on their the activities of daily living. The subjects of this study were 30 stroke patients who were admitted to T$\breve{a}$e-Bong hospital from November, 2002 to March, 2003. The subjects were administerd an MMSE as a cognitive assessment and an MBI as a functional assessment upon referral to physical therapy initially. The results were as follows: 1. The MMSE scores for the stroke patients were related to the patients' abilities to perform their activities of daily living. The changes of MBl scores significantly correlated with the changes of MMSE scores (p<.05). 2. The subjects with left hemispheric lesion scored higher in MMSE than those with right hemispheric lesions (p<.05). 3. The hemispheric lesions did not significantly affect the activities of daily living score (p>.05).

본 논문에서는 평균제곱오차(mean-square-error)를 최소화하며, 여러 사용자 양방향 통신(bidirectional communications)을 지원하는, 증폭-후-전달(amplify-and-forward) 중계기의 송수신 가중치 행렬을 제안한다. 또한, 시스템 전송량을 최대화하는 각 사용자 빔포밍(beamforming) 벡터를 설계한다. 모의실험을 통해 제안한 중계기 가중치로 여러 사용자간 상호채널간섭(co-channel interference)과 양방향 통신에서 발생하는 자기간섭(self-interference)을 효과적으로 줄일 수 있음을 보이고, 또한, 제안한 빔포밍 방식이 공간 다중화(spatial multiplexing) 방식에 비해 증폭-후-전달 중계기 양방향 통신에 적합함을 확인하였다.

Purpose: This study was conducted to assess the level of agreement among survey instruments used to study dementia and to determine the prevalence rate of suspected dementia using different instruments. Subjects and Methods: A total 171 subjects older than 65 in Gyeongju-si, Gyeongsangbuk-do, were surveyed from February to October 2003. The age, sex and educational level were examined through interview surveys, and cognitive function was evaluated using three survey instruments including MMSE-K, S-SDQ, and KDSQ. Results: The cognitive function scores obtained with the MMSE-K showed significant difference according to age. For sex and educational level significant differences were observed with all three survey instruments. The kappa index, the level of agreement between the questionnaires, was 0.302 between MMSE-K and S-SDQ, 0.401 between MMSE-K and KDSQ, and 0.762 between KDSQ and S-SDQ. The prevalence rate of suspected dementia based on the criteria suggested by MMSE-K, S-SDQ, and KDSQ was 27.5%, 15.2%, and 17.0% respectively. Conclusion: The results of this study suggest that caution is needed when comparing the measured cognitive function scores and analyzing the prevalence of dementia; this is because the prevalence of dementia and cognitive functions vary according to the questionnaires used.

시공간 부호화기법을 가진 MIMO(Multiple-input multiple-output)-OFDM(Orthogonal frequency division multiplexing)은 미래의 무선통신 시스템에서 성능향상을 위한 약속된 기술이다. 그러나 다중 송신기를 가진 다른 사용자에 따른 간섭과 다중경로의 지연신호에 따른 영향으로 성능이 크게 감소된다. 이 논문에서는 MIMO-OFDM 시스템에서 시공간 다이버스티를 유지하면서 이와 같은 간섭신호와 다중경로 지연신호를 효율적으로 제거하기 위하여 MMSE(minimizing the mean squared error) 기반의 pre-FFT 다중 빔형성기법을 제안한다. MIMO-OFDM 시스템에 제안된 다중 빔형성기법을 적용할 경우 성능 개선 효과를 CCI(Cochannel interference)를 가진 다중경로 채널환경에서 모의실험을 통하여 확인한다.

Purpose: The purpose of this study was to compare the degree of attitude toward elders, cognitive level, and mood state by living arrangements of the elderly. Method: The subjects consisted of 238 elderly who divided by living arrangements(living alone, living with spouse, living with children). The data were collected by structured questionnaire that included general characteristics, attitude toward elders, MMSE-K and mood state scale, from March to December, 2005. The collected data were analyzed by Windows SPSS program including descriptive statistics, ${\chi}^2-test$, Fisher's exact test, ANCOVA, $Scheff{\grave{e}}$ test and Pearson Correlation Coefficient. Results: In MMSE-K and mood state, there were statistically significant differences among the three groups. In depression and anxiety factor of mood state, the living alone group showed higher scores than the other two groups. There was a positive correlation between attitude toward elders and MMSE-K in the elderly living with a spouse group and a negative correlation between MMSE-K and mood state in all three groups. Conclusion: It is necessary to develop a supportive program for decreasing the risk of health in the elderly and perform a differential approach according to their living arrangementa. Especially, more concern and intervention are needed to be performed for the elderly living in solitude.

Ginseng shows protective and trophic effects in neurodegenerative diseases in experimental models, and showed cognitive improvement in normal population. To investigate the efficacy of ginseng in patients with Alzheimer's disease, patients, who met NINDS-ADRDA criteria for AD were studied Subjects were randomly assigned to ginseng group and control group, and ginseng group was treated with Korean white ginseng powder (4.5 g/day) for 12 weeks. Efficacy variables included changes in mini-mental status exam (MMSE) and cognitive subscales of Alzheimer's disease assessment scale (ADAS-cog) at 4 weeks and 12 weeks. Baseline MMSE and ADAS scores showed no difference between the two groups. Results showed that ginseng improved ADAS-cog compared to the control group at 12 weeks (p<0.05). MMSE was also increased by ginseng treatment compared to the control at 12 weeks (p<0.01). This study suggests the symptomatic efficacy of ginseng in patients with Alzheimer's disease.

Purpose: The purpose of this study was to compare the degree of cognitive level, nutritional status and depression in elderly according to living situations. Method: The subjects consisted of 173 elderly classifying three groups(living alone, living with spouse, living with children). Data was collected from March to June, 2003 by a structured questionnaire that included general characteristics, MMSE-K, nutritional status and depression scale. The collected data was analyzed by the SPSS program including descriptive statistics, $\chi$$^2$-test, ANCOVA, Scheffe test and Pearson Correlation Coefficient. Result: In MMSE-K, the living alone group showed suspicious dementia while the other groups were normal. The living alone group showed a high nutritional risk and all three groups showed depression. In MMSE-K, the nutritional status and depression were statistically significant by the living situation. In each group except living with spouse, MMSE-K indicated a significantly negative correlation to depression and nutritional status, while nutritional status showed a significantly positive correlation to depression. Conclusion: It is necessary to develop supportive programs for decreasing the risk of bad health in the elderly and an individual approach according to their living situation. Especially, more concern and intervention is necessary for the solitary elderly.
