Objective: This study aimed to evaluate the effects of a digital group reminiscence program on elderly patients with mild dementia who were registered with Day Care Centers. Methods: The study was conducted with elderly patients with mild dementia in Day Care Centers in D city. The patients were randomly assigned to either the experimental group or the control group and were assessed for cognitive function, depression, and ego integrity using pre-test and post-test designs. A digital group reminiscence program was applied to the experimental group. Data was collected from July 5 to September 17, 2021, using questionnaires in three sessions. Results: The pre-test cognitive function score was 12.00 in the experimental group and 11.09 in the control group. The post-test cognitive function score was 19.20 in the experimental group and 14.42 in the control group. The later cognitive function score was 18.00 in the experimental group and 13.31 in the control group. The pre-test depression score was 8.32 in the experimental group and 9.91 in the control group. The post-test depression score was 6.05 in the experimental group and 8.82 in the control group. The later depression score was 6.94 in the experimental group and 9.02 in the control group. The pre-test ego integrity score was 41.39 in the experimental group and 39.55 in the control group. The post-test ego integrity score was 57.95 in the experimental group and 51.41 in the control group. The later ego integrity score was 55.88 in the experimental group and 42.15 in the control group. Cognitive function, depression, and ego integrity showed significant differences according to group (p<.05), time (p<.001), and interaction between group and time (p<.01). Conclusion: The digital group reminiscence program was found to be effective in improving cognitive function and ego integrity and reducing depression in elderly patients with mild dementia. Further research is needed to explore the effects of repetitive digital group recall programs based on the progress, course, age, and communication level of dementia.

This paper is mainly concerned with the ship-bank interaction by model test. The experiments for the characteristics of hydrodynamic interaction forces and moments between vessel and bank with a mound were carried out in the seakeeping and maneuvering basin. A series of tests were carried out with ship model in parallel course along a vertical sidewall with a mound with varying lateral spacing between model ship and sidewall, length of sidewall and water depth. From the experimental results, it indicated that the hydrodynamic interaction effects increase as length of sidewall with a mound increases. Furthermore, for lateral spacing less than about 0.2L between vessel and bank, it can be concluded that the bank effects increase largely as the lateral spacing between vessel and bank decreases. However, for spacing between vessel and bank more than about 0.3L, the interaction effects increase slowly as lateral spacing decreases. Also, for the water depth to draft ratio(h/d) less than about 1.5, the hydrodynamic interaction effects increase dramatically as h/d decreases.

The study was undertaken to assess the degree to which subjects were compliant with a specific metabolic diet in a controlled outpatient feeding study. The study consisted of a two-week control period in which subjects consumed a control diet consisting of 38-40% fat, 18-20% protein, 40-42% carbohydrate, followed by a three-week experimental period during which each subject consumed the control diet plus one of the four fiber supplements(20g/4ay) assigned on a random basis on the trust day. All meals were prepared and eaten in a metabolic feeding laboratory, with the exception of Saturday and Sunday meals that were packed for take-out. Fifty-seven healthy adult men, aged 18-65 years participated in the study. Dietary compliance index(CI) defined as the percent deviation of actual consumption from the prescribed food's and unconsumed prepared foods. The CI reflected the additional 'non-prescribed foods' and unconsumed 'prescribed foods'. A CI was calculated for all subjects. A CI of 5% or more was defined as poor compliance. Overall, dietary compliance was substantially improved for the entire group over the course of the study. Significant increase in compliance far energy and macronutrient intake occurred between the baseline and experimental periods. Within a non-obese group, dietary compliance fir energy improved from 5.5% to 3.3% by the end of the study(week 1vs week 5, respectively, p<0.05). However, between non-obese and obese group, dietary compliance was not different. (Korean J Nutrition 31(5) : 957-964, 1998)

사람들은 애니메이션을 다른 예술분야와 비교하여 유치하거나 어린이들을 위한 하위문화라고 생각해왔다. 물론 최근에는 이러한 양상이 많이 바뀌었지만 여전히 애니메이션은 문화적 또는 예술적 측면보다는 상업적 측면에 초점을 맞추고 있다. 그러나 단편 애니메이션을 중심으로 다양한 실험적 표현들을 사용한 예술적인 애니메이션도 지속적으로 제작되고 있다. 따라서 본 논문에서는 상업적인 측면보다는 실험적이고 작가적 성향이 짙은 퀘이 형제의 애니메이션 특성을 살펴본 후, 그들의 대표작 <악어의 거리>의 크로테스크성을 분석하고자 한다. 또한 그들이 크로테스크한 표현을 통하여 이 애니메이션에서 나타내고자 하는 의미들을 고찰하고자 한다.

Variation of brain dynamics under Zen meditation has been one of our major research interests for years. One issue encountered is the inaccessibility to the actual meditation level or stage as a reference. In this paper, we propose an alternative strategy for investigating the human brain in response to external flash stimuli during Zen meditation course. To secure a consistent condition of the brain dynamics when applying stimulation, we designed a recording of flash visual evoked potentials (F-VEPs) based on a constant background EEG (electroencephalograph) frontal $\alpha-rhythm$ dominating activities that increase significantly during Zen meditation. Thus the flash-light stimulus was to be applied upon emergence of the frontal $\alpha-rhythm$. The alpha-dependent F-VEPs were then employed to inspect the effect of Zen meditation on brain dynamics. Based on the experimental protocol proposed, considerable differences between experimental and control groups were obtained. Our results showed that amplitudes of P1-N2 and N2-P2 on Cz and Fz increased significantly during meditation, contrary to the F-VEPs of control group at rest. We thus suggest that Zen meditation results in acute response on primary visual cortex and the associated parts.
