본 논문에서는 휴머노이드 로봇이 더욱 지능적으로 보행할 수 있도록 강화학습을 적용하는 방법을 제안한다. 강화학습을 활용하면 로봇의 이동 경로에 동적으로 이동하는 장애물이 있을 경우 이를 인지하고 회피하여 목적지까지 문제 없이 이동할 수 있다. 실제 환경에서의 실험에 앞서 Unity3D를 활용한 가상 환경에서 이를 구현하여 실험해보았다.

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.

To examine the cognitive function of onion (Allium cepa L.) beverages (odourless and fortified), we analyzed in vitro neuronal cell protection against $H_2O_2$-induced cytotoxicity and performed in vivo tests on amyloid beta ($A{\beta}$)-induced cognitive dysfunction. Cellular oxidative stress and cell viability were evaluated by DCF-DA assay and MTT assay. These results show that fortified beverage resulted in better neuronal cell protection than odourless beverage at lower concentration ($0{\sim}100{\mu}g/mL$). Fortified beverage also showed more excellent acetylcholinesterase (AChE) inhibitory activity ($IC_{50}$: 4.20 mg/mL) than odourless beverage. The cognitive functions of odourless beverage and fortified beverage in $A{\beta}$-induced neurotoxicity were assessed by Y-maze, passive avoidance, and Morris water maze tests. The results show improved cognitive function in both groups treated with beverages. After in vivo tests, cholinergic activities were determined based on AChE inhibition and acetylcholine levels, and antioxidant activities were measured as SOD, oxidized glutathione (GSH)/total GSH ratio, and MDA levels in mouse brain tissue. In a Q-TOF UPLC/MS system, main compounds were analyzed as follows: odourless beverage (five types of sugars and three types of phenolics) and fortified beverages (six types of phenolics and two types of steroidal saponins).

We aimed to provide evidences for developing non-pharmacological intervention in older adults with Mild Cognitive Impairment(MCI) by integrated literature review. The final 16 papers were selected as a result of an integrated literature analysis. All of them are focused on strengthening cognitive activities, while Korean studies have often merged emotional activities such as music therapy and laughter therapy rather than physical activities such as exercise therapy, international studies have combined physical activities rather than emotional activities. The effects of non-pharmacological intervention differed according to the outcome variables. The primary variables were cognitive function and depression, and secondary variables were found to have effects on physical function, activities of daily living (ADL), and self-efficacy. This study contributes to a multidisciplinary approach that can be applied in the clinical field through the development of various non-pharmaceutical intervention for the prevention of dementia in the older adults with MCI.

This research the impacts of the experiential marketing elements to the festival brand loyalty and the results are as follow. First, the research showed 2 difference parts as the age and income in the experience and cognitive items. Second, it showed all items of sensory experiences of experiential marketing, emotional experience, cognitive experiences positively affect to the festival brand loyalty. Through these results, first, we could suggest a new data for the development of the festival experience marketing for the enhancement of the festival brands in the future. Second, as the new research applying the festival and experiential marketing, we could found the experiential marketing through the intangible goods as like the festival could affect to the reinforcing of the brand loyalty.

Purpose: This study was aimed at constructing and examining the effects of a laughter therapy program for elderly patients in long-term care hospitals. Methods: A prospective, two-group quasi-experimental design was used and 50 patients (25 experimental and 25 control group patients) from two long-term care hospitals in Gyeonggido province, South Korea, were study participants. The experimental group received 24 laughter therapy sessions twice a week for 12 weeks, and the control group received laughter therapy after data collection. Data were collected between May 26 and August 17, 2014. Results: The level of cognitive function for the experimental group increased(t=3.27, p=.002). The level of forced vital capacity (t=2.78, p=.008) and forced expiratory volume in 1 second (t=4.94, p<.001) increased among members of the experimental group. Conclusion: These results indicated that the laughter program was effective in improving cognitive and pulmonary functions among older patients who were receiving long-term care in hospitals. This program could be used for community-based elderly patients.

전통적인 수학교육은 간단한 수학적 사실을 이해하고 활용하는 측면에 있어서는 효과적일 수도 있지만, 수학적 개념, 원리, 법칙을 학생 스스로 탐구, 발견하고 창조하는 능력을 기르는 데는 적절하지 않다. 이러한 능력을 기르기 위해서는 학생들 스스로가 관찰, 조작, 분석, 종합하는 활동을 강화할 필요가 있다. 구체적 조작물을 학습도구로 활용하는 경우, 수학 학습에 대한 흥미와 자신감을 길러 주고, 자신의 수준에 맞는 내용을 자기 주도적 학습을 통하여 성취감을 가지게 하며, 학생 스스로 탐구 활동을 활발히 하는데 도움이 된다. 삶의 질이 급격히 향상되는 정보사회에서는 사이버 공간의 등장으로 공간감각 기능의 필요성이 더욱 절실한 바, 현행 수학교과서에서 제공되는 각종 공간 도형들은 3차원 공간에서 이루어지지 않고 평면도형으로 처리함으로써 아동의 도형인지 능력 향상에 큰 효과를 기대하기 어렵다. 이에 본 연구에서는 아동의 인지발달 단계를 고려, 도형인지능력 향상을 위한 선 및 점대칭 관련 동기유발, 선수, 기본, 보충, 심화, 평가, 도움말 관련 프로그램을 개발, 적용한 결과 학습자의 동기가 유발되고, 도형 인지능력 향상에 유의미한 결과를 얻었다.

This study aims to understand crucial factors affecting user's Fintech payment service adoption. On the basis of innovation diffusion theory and prior Fintech literature, this study classifies the influence factors of users' adoption of Fintech payment service into two dimensions - service dimension containing complexity, perceived benefit, trust in service provider and user dimension containing personal innovativeness and security breach experience. The data analysis results using binary logistic regression shows the negative direct effects of perceived risk, complexity, security accident experience on user's service adoption are statistically significant. Personal innovativeness has a positive effect on user's Fintech payment service adoption. The moderation effect of security accident experience is also significant at p<0.05.

This study purposed to examine the effect of the horticultural therapy on activities of daily living and cognitive function of demented old adults in facilities. According to the results of evaluating BADL, the ability to perform daily activities decreased from 9.71 to 9.21 in the control group, but in the experimental group, the ability to perform daily activities increased significantly(p=.009) from 10.86 before the horticultural therapy to 12.43 after the therapy. According to the results of evaluating K- MMSE, the score decreased from 10.57 to 9.07 in the control group, but the experimental group showed a significant improvement in cognitive functions from 10.43 before the horticultural therapy to 13.29 after the therapy(p=.003). As presented above, the horticultural therapy was effective in improving activities of daily living and cognitive function of demented old adults.
