This study aimed to investigate variables affecting subjective memory impairment in the elderly with benign prostatic hyperplasia. We used 179 survey data collected from the urology department of two metropolitan general hospitals. The subjects were patients with benign prostatic hyperplasia. T-test, one-way analysis of variance, and $Scheff{\acute{e}}^{\prime}s$ test were performed to identify differences among variables. Pearson's correlation-coefficient and stepwise multiple regression were used to identify variables that affect subjective memory impairment. This study revealed that lower urinary tract symptom and activities of daily living were statistically significant variables, with an explanatory power of 30.0%. The lower urinary tract symptom was due to the benign prostatic hyperplasia increasing the risk of subjective memory impairment. Treatment of the lower urinary tract symptom was delayed because as the elderly got older, they increasingly recognized benign prostatic hyperplasia as a reasonable symptom. Timely intervention and early screening are necessary to prevent lower urinary tract symptom. Finally, programs to reduce the incidence of lower urinary tract symptom and educate nurses to assess, evaluate, perform intervention for subjective memory impairment should be developed.

This research investigated differences of perception ratio and processes of memory reconstruction. To examine the differences in perception for positive or negative events related to individual subjective well-level, 199 participants were asked to report the perceived ratio of positive versus negative events for the provided event list. Also, recall differences of positive versus negative events were examined in relation to individual differences in happiness. Results partially supported the hypothesis that happy people perceive more positive stimulus in a given situation than less happy people. Happy people also showed more positive percentage in recalled events than actual ratio while unhappy people reported less positive recall percentage than actual ratio. These findings indicate existence of cognitive process that enhances positive or negative memory related to subjective well-being. Significant correlation between perceived ratio and recalled ratio further supports this proposition. Finally, theoretical implications of the present research and suggestions for future research were discussed.

This qualitative study employed focused group interviews to collect data on the forgetfulness experienced by elderly persons (over the age of 65) who suffer with subjective memory impairment. The participants were ten elderly persons who participated in the cognitive function improvement program at an elderly welfare center in D city. They were divided into three groups that were comprised of three/four people each, and each group was interviewed for 40~60 minutes. The results showed that "difficulties in human relations", "feeling uncomfortable in daily life", "exposure to a safety risk", "inexpressible ambivalence" and "family effort to overcome forgetfulness" were all expressed in the interviews. The elderly who participated in this study and who complained of subjective memory impairment had both feelings of anxiety and anxiety about non-dementia, and they were making efforts to overcome forgetfulness themselves. Based on this study, we suggest that interventions should be developed that reflect the individual needs of elderly people with subjective memory impairment.

The loss of semantic knowledge and impairments in semantic associations by semantic category is gaining increasing attention, as indicators of early-stage cognitive decline. As such, we assigned semantic association task (SAT) to normal elderly (NE) and those with subjective memory impairment (SMI) or mild cognitive impairment (MCI) to examine their performance by semantic subcategories and the differences in error patterns. We found a significant difference in the number of correct response and reaction time under the SAT categories among the three groups, with the highest performance observed in 'function' and the lowest performance in 'superordinate' and 'part/whole'. Moreover, the error frequency was the lowest in NE, followed by those with SMI and MCI, with the latter two groups showing a significant increase in no-response. Our findings demonstrate the varying extent and process of impairments in the semantic network by category over different stages of cognitive decline. Thus, we proposed SAT performance as an indicator to detect and follow-up on cognitive decline in elderly with cognitive disorder.

The present study investigated the related variables of cognitive function, subjective cognitive decline and cognitive training effects. The cognitive training was composed of mete-cognitive education and cognitive task performing. Twenty older adults attended for 14 weeks and were tested before and after the training. Results show that their cognitive level was related with age, self-esteem and personality traits. And subjective cognitive decline was related depression, anxiety, personality traits, self-efficacy, self-esteem and subjective age, but it does not reflect objective cognitive impairments. Their cognitive test scores were enhanced after training in MMSE, memory and executive function, and enhanced scores were related with age, subjective cognitive decline, anxiety, self-efficacy, self-esteem, subjective age and personality traits. Findings suggest one's personality and psychological state need to be considered for the effects of cognitive training.

본 연구는 형용사를 이용한 향의 이미지 구조 연구에서 자극을 사용한 경우와 향을 제시하지 알은 두 경우를 비교하였다. 자극을 제시한 실험에서는 피험자에게 5가지의 향 자극을 주고 각 향에 대한 이미지를 25개의 형용사에 대하여 7점 척도로 표시하도록 하였다. 자극을 제시하지 않은 실험은 쌍 비교법을 사용하여 형용사를 두개 씩 쌍을 지워 제시하고 두 형용사가 유사한 정도를 7점 척도로 나타내게 하였다. 두 자료를 다차원 척도 (MDS), 군집분석, 상관관계를 이용하여 분석을 실시하여 비교하였다. 결론적으로 향의 이미지 구조는 자극 제시여부에 따라 구조적이며 근본적인 차이가 없음이 밝혀졌다. 그러나 자료 분포의 밀집정도에 따른 지엽적인 차이는 있었으며 이러한 차이는 두 경우에 적용되는 기억이, 단기기억과 장기기억으로, 다르다는 점에서 기인되는 것이 라고 판단되었다.

This study is an experimental study on the single group pre-post test design for the effects of the food expression activity program on subjective memory, depression, and self-expression of the elderly. 36 elderly people attending Senior Citizen Club from two locations in S City participated. A total of six session programs were applied from January 8 to February 17, 2020. The questionnaire survey conducted subjective momory, depression, and self-expression before and after the program. The contents of the intervention consisted of physical relaxation, cognitive activities, and various food activities. In the result of this study, the food expression activity program were statistically significant differences in subjective memory(t=2.67, p=.011), depression(t=3.88, p<.001), and self-expression(t=2.09, p=.044). Therefore, it is expected that the food expression activity program can be applied as a nursing intervention to reduce depression and improve subjective memory and self-expression in the elders attending senior citizen clubs.

This study examined the effect of cognitive reserve on the cognitive function in adults. In addition, this study investigated the direct and indirect effects of factors, such as subjective memory decline, depression, and quality of life on the cognitive function. The participants consisted of 253 adults who were 40 to 80 years of age. The assessment tools included the cognitive function scale, depression scale, quality of life scale, subjective memory decline, and cognitive reserve scale. The data results were analyzed using SPSS 25.0, and PROCESS macro for SPSS Version 3.3 and bootstrapping were used. The results of multiple mediating of the cognitive reserve and cognitive function in adults did not have a mediating effect in depression and subjective memory decline, and the quality of life showed a complete mediating effect in the relationship between the cognitive reserve and subjective cognitive function. Based on the results of this study, adults must accumulate cognitive reserve continuously through various activities and continuous training so that the cognitive function can lead to a positive direction. Nevertheless, more studies on cognitive reserve and cognitive function in healthy adults are needed.

The purpose of this study is to investigate the effect of a community-based cognitive stimulation program on cognitive function and subjective memory in the elderly with mild cognitive impairment. This study was applied by selecting 15 users who understood the purpose of this study and agreed to participate in the shelter program for more than 3 months from April 2019 to August 2019 at the D Dementia Center in G located, Gyeonggi-do. The program consisted of a total of 36 cognitive stimulation programs 3 times a week a total of 3 months. Cognitive stimulation program stimulates cognitive function through various activities such as orientation reinforcement, cognitive training, recall, music, art, and physical play, and is used for the purpose of improving social function. It consists of folk songs, percussion instruments, national gymnastics, dance, games, and traditional games. As a result of the cognitive stimulation program, the average cognitive function increased by 2.13 points from 26.33 points before implementation to 28.46 points after implementation, and a statistically significant result was obtained (p=0.000). Subjective memory decreased by 3.53 points from the average of 7.13 points before the cognitive stimulation program was implemented to 3.60 points after the implementation, and a statistically significant result was obtained (p=0.000). It can be confirmed that this works. Dementia is leading to a cost burden, and congnitive function decreases the aqulity of life. It brings various burdens. It is necessary to study cognitive stimulation programs applied to various environments in the future.
