  • Purpose: The purpose of this study was to identify the effects of an exercise program on frontal lobe cognitive function in seniors. Methods: The participants were 42 seniors using a health center in Seoul (experimental group) and 28 seniors using a facility for elders in Seoul (control group). The exercise program was carried out for 16 weeks from April to August 2007. The frontal lobe cognitive function, which includes short term memory, attention, immediate memory, delayed memory, verbal fluency and motor function, was measured by the Digit Span Forward test, Trail Making test, Immediate recall words test, Delayed recall words, Controlled oral word association test and Finger tapping test. The collected data were analyzed by Fisher's exact test, Chi-square, t-test, and ANCOVA using the SAS program. Results: The major findings of this study were as follows: Attention (p=.009), immediate memory (p=.005), delayed memory (p=.009), and verbal fluency (p=.004) improved after the exercise program. Conclusion: In this study, the exercise program was effective in improving frontal lobe cognitive function in elders. So it provides basic information for further nursing education on exercise programs which will be effective for prevention of early cognitive function decline in normally aging elders.

  • Objectives : It was the aim of the present paper to examine the impact of the apolipoprotein E(APOE) ${\varepsilon}4$ on cognitive performance in community-dwelling elderly samples with 'questionable dementia'. Methods : Total 295 samples who were diagnosed with 'questionable dementia' in the recent year and completed the Korean version of the Consortium Establish a Registry for Alzheimer's Disease(CERAD-K) neuropsychological assessment protocol, were recruited. The CDR test established score of 0.5. Genomic DNA was extracted from the venous blood and APOE genotyping was done in this group. Their cognitive performance was compared by the occurrence of the APOE ${\varepsilon}4$ allele. Results : The impact of ${\varepsilon}4$ allele was significant in the Word List Recall Test(WLRT, F=4.511, df=1, p=0.035). The 'young-old' group aged 75 years and under had a significantly lower performance on the Word List Recall Test(WLRT, F=5.090, df=1, p=0.015), but the 'old-old' group over 75 years of age had not significantly different performance on the all the item of tests in ${\varepsilon}4$+ allele group. Conclusion : The conclusion to be drawn here is that community-dwelling elderly samples with ${\varepsilon}4$ allele in 'questionable dementia' had a significantly lower performance on the Word List Recall Test in the CERAD-K neuropsychological test batteries and the effect was prominent in the 'young-old' age group.

  • We define a broad class of rotation designs whose monthly sample is balanced in interview time, level of recall, and rotation group, and whose rotation scheme is time-invariant. The necessary and sufficient conditions are obtained for such designs. Using these conditions, we derive a minimum variance unbiased generalized composite estimator (MVUGCE). To examine the existence of time-in-sample bias and recall bias, we also propose unbiased estimators and their variances. Numerical examples investigate the impacts of design gap, non-sampling error sources, and two types of correlations on the variance of MVUGCE.

  • The purpose of this study is to find out what type of skip button used in forced exposure advertising is the most positive to the users. The four types of skip buttons were produced for the experiment and tested by survey and eye tracker to reveal the effects of the skip buttons on perceived intrusion, advertising attention, attitude toward advertising, and memory consisting of recall and recognition. Out of 80 participants, 20 were randomly assigned to the specific type of skip button group. The results showed that there is no statistical difference in advertising attention, perceived intrusiveness and attitude toward advertising. However, the recall and recognition rate are the highest in the static text type and kinetic text, product image, and default follow statistically. This study has implications for using skip buttons as a major variable for inventory of TrueView advertising effects and suggests that the amount of information in the image is critical processed by users within very short time.

  • Objectives Although forgetfulness is a common complaint among menopausal depressed women, there is still a debate about the relationship between memory impairment and menopause. The aim of this study is to examine whether menopause is related to cognitive decline among women with depressive disorders. We hypothesized that postmenopausal depressed women show generally poorer performance than premenopausal depressed women on various cognitive function tests. Methods With a retrospective chart review, we identified a total of 87 female patients (45 premenopausal patients and 42 postmenopausal patients) who were hospitalized with depressive disorders from 2000 to 2016. Demographic and clinical variables and cognitive test results were compared between two groups. Results Education year is longer in premenopausal group than postmenopausal group whereas clinical characteristics (illness duration, recurrence, and symptom severity) and mean Intelligence Quotient (IQ) were similar between two groups. The postmenopausal group took longer time for Bender-Gestalt Test (BGT) recall, Trail Making Test (TMT)-A, and TMT-B than the premenopausal group. After controlling for age and education, significant difference was remained for BGT recall (p = 0.029). Conclusions Postmenopausal state may be related with decline of visuospatial memory function, in particular, among depressed female patients. Other areas of cognitive function including complex attention, verbal memory, auditory memory, and working memory might be interpreted while considering age and education level.

  • 본 연구는 알츠하이머 치매노인을 대상으로 Apolipoprotein E (ApoE) ɛ4의 유무와 치매수준에 따른 우울과 기억력의 상관관계를 분석하고자 하였다. 임상치매척도(clinical dementia rating; CDR)가 0.5점에서 2점 사이인 65세 이상 노인 50명을 대상으로 임상치매척도, 노인용 서울언어학습검사, 레이 복합도형검사, 축약형 노인우울검사를 실시하였고 ApoE 유전자형은 구강상피세포를 채취하여 실시한 유전자 검사를 통해 확인하였다. 자료분석은 맨 휘트니 U 검정, 상관관계 분석을 실시하였다. ApoE ɛ4가 없는 경우에 CDR 1점과 2점에서 우울과 언어적 즉시회상 기억력이 유의한 음의 상관관계가 있었고(p<.05), ApoE ɛ4를 보유한 경우에는 CDR 1점에서 우울과 언어적 즉시회상, 언어적 지연회상 기억력에서 유의한 음의 상관관계가 있었다(p<.05). 우울과 언어적 즉시회상 기억력은 유의한 상관관계가 있었고 ApoE ɛ4를 보유한 경우에는 우울과 언어적 지연회상 기억력에도 유의한 상관관계가 있었다. 따라서 알츠하이머 치매의 예방 및 중재로 시각적인 훈련보다 언어적 기억력훈련이 유용할 것이며 우울치료가 상호보완적으로 도움을 줄 수 있을 것으로 기대한다.

  • This study was a quasi-experimental study to confirm the effects of a memory training program using efficacy sources. The purpose was to develop an effective memory training program for elderly people and to identify the effects of the memory training program. This study was carried out between February 24 and July 18, 1999 and the subjects of the study were 102 elderly people who were participants at a welfare institute in Seoul. The experimental group (51) and the control group (51) were assigned by means of participation order. The control group was matched to the experimental group and was selected considering age, sex, and religion. The experimental group participated in the memory training program. The memory training program was based on the literature of Fogler & Stern (1994), Wang & Lee (1990), Lee (1991) and Lee (1993). The memory training program was given twice a week for two weeks with each program lasting two hours. Task centered memory self-efficacy was measured using the Memory Self-Efficacy Scale developed by Berry & Dennehey (1989) and Meta Memory was measured by the MIA developed by Dixon et al. (1988) Memory performance was measured by the word list developed by Cho Sung Won (1995) and the face recognition task (Face Recognition Task developed for this study). Data were analyzed by SPSS PC and the results are described below. 1. The experimental group which participated in the Memory Training Program showed higher task centered memory self-efficacy scores as compared to the control group (t=4.354, P=.0001). 2. The experimental group which participated in the Memory Training Program showed higher metamemory scores as compared to the control group (t=4.733, P=.0001). 3. The experimental group which participated in the Memory Training Program showed higher memory performance scores as compared to the control group (t=7.500, P=.0001). The memory performance involved an immediate word recall task, a delayed word recall task, a word recognition task, and the face recognition task. 4. In the experimental group, there was significant correlation between the task centered memory self-efficacy scores and the metamemory scores (r=.382, P=.006), but the correlation between the task centered memory self-efficacy scores and the memory performance scores and between the metamemory scores and the memory performance scores were not significant. The results showed that task centered memory self-efficacy, meta memory and memory performance improved following the Memory Training Program including the memory process, changes in memory with aging, and appropriate use of memory strategies. Memory Training Program is an effective nursing intervention for improving memory in elderly people and, also, in people with complaints of memory loss.

  • This study was conducted to investigate the body weight status (by WLI: Weight-Length Index) and dietary habits and to assess the nutritional status among preschool children in the Daegu area. Dietary habits including dietary attitude and behavior were investigated using questionnaire answered by mothers of 680 subjects aged 4 to 6 years old (508 completed). Also, dietary intake survey using 24-hour recall method was performed by mothers of the children. According to WLI, the underweight, normal, overweight and obesity level of subjects were 9.1, 62.0, 19.5, and 9.4%, respectively. As well, the number of girls was higher than boys in underweight, overweight, and obese group. There were significantly different on overeating, eating fast, and preferring eating-out by body weight status, and overweight group got higher score than underweight or normal-weight group (p < 0.01, p < 0.001). As well, there was significantly different on not moving around during mealtime by body weight status, and underweight group have lower score than obese group (p < 0.001). From the 24-hour recall survey, it was found that intakes of all the nutrients were higher than the %KDRI except energy, calcium and folate. The energy intake of underweight group of 4~5-year old (1338.2 kcal) and 6-year old was lower than Koreans %DRI for those age group. Folate and dietary fiber intakes of obese group were significantly lower than underweight (p < 0.01, p < 0.05). For 4~5-year old, vitamin $B_6$ intakes of obese group were significantly higher than obese group (p < 0.05). For 6-year old, obese group showed that intake of vitamin $B_1$ was significantly higher than the other three groups, and intake of vitamin $B_1$ of overweight group was significantly higher than the other three groups. Taken together, these results indicate that there were significant differences in the nutrient intake level and dietary habits of preschool children by body weight status in Daegu area. Therefore, parents (family) and caregivers should be aware of the prevalence of obesity and nutritional status of preschool children, and start nutrition education as soon as possible.

  • This study was conducted to estimate the prevalence of ametropias such as myopia and hyperopia from the community based population study. Another purpose of this study was to determine the association between ametropia and nutrient intake. The study subjects was 492 residents over 20 years of age residing in Kuri City. Ametropia was tested based on re(rector error using auto referactor. Nutrient intake was estimated from the dietary survey using 24 hour recall method. As a result of data analysis, the prevalence of myopia was 57% and that of hyperopia was 11%. Such a high rate of ametropia prevalence may suggest the increasing risk of eye health in a Korean society. Nutrient intake of myopia group was 5∼15% higher than that of normal group in most of the nutrients. Whereas intake of most nutrient except calcium, retinal, fiber for the hyperopia group was lower than that of normal group. The result may suggest that inbalance of nutrient intake has been related with ametropia.
