Successor representation (SR) is a model of human reinforcement learning (RL) mimicking the underlying mechanism of hippocampal cells constructing cognitive maps. SR utilizes these learned features to adaptively respond to the frequent reward changes. In this paper, we evaluated the performance of SR under the context where changes in latent variables of environments trigger the reward structure changes. For a benchmark test, we adopted SR-Dyna, an integration of SR into goal-driven Dyna RL algorithm in the 2-stage Markov Decision Task (MDT) in which we can intentionally manipulate the latent variables - state transition uncertainty and goal-condition. To precisely investigate the characteristics of SR, we conducted the experiments while controlling each latent variable that affects the changes in reward structure. Evaluation results showed that SR-Dyna could learn to respond to the reward changes in relation to the changes in latent variables, but could not learn rapidly in that situation. This brings about the necessity to build more robust RL models that can rapidly learn to respond to the frequent changes in the environment in which latent variables and reward structure change at the same time.

Objective : This study was to apply a cognitive rehabilitation group program based on sensory activity in patients with dementia living in a facility and to check its effectiveness on cognitive function, depression, and quality of life (QOL). Methods : Sensory-based cognitive rehabilitation group programs (20 sessions) were conducted for eight elderly with dementia over the age of 65 living in a nursing facility located in H-gun, Gangwon-do. The participants' cognitive function, depression level, and QOL were evaluated before and after the program. Results : The mean of Mini-Mental State Examination-Dementia Screening increased; however, there was no statistically significant difference. In contrast, the mean post-test score of the Subjective Memory Complaints Questionnaire decreased, and there was a statistically significant difference (p < .05). The mean post-evaluation score of Short Geriatric Depression Scale measured to confirm the decrease in depression compared to the pre-evaluation score, but there was no statistically significant difference. Finally, the mean post-evaluation score of the World Health Organization QOL assessment instrument-Brief confirmed the change in the QOL, and there was a statistically significant difference (p < .001). Conclusion : This study will provide the basis for suggesting the usefulness of developing a sensory activity-based cognitive rehabilitation group program for dementia patients living in facilities.

This study aims to investigate the differences in burnout, emotional labor strategies, affect intensity, and emotional clarity based on combinations of level of mindfulness and compassion. To achieve this, a total of 137 mental health professionals participated in this study, and they were classified into four groups based on their level of mindfulness and compassion using cluster analysis. Then, the differences among the groups were compared. The results of the multivariate analysis of covariance(MANCOVA) or multivariate analysis of variance(MANOVA) controlling for career experience, showed that the group with high levels of both mindfulness and compassion had the highest levels of positive affect intensity, emotional clarity for self and others, and genuine expression, while having the lowest levels of negative affect intensity, surface acting, and burnout. In comparison to the group with high levels of both mindfulness and compassion, the group with high or low level of either mindfulness or compassion had both positive and negative affect intensity at higher or lower levels. Additionally, they showed lower emotional clarity for self and others, and genuine expression. Conversely, they showed higher levels of surface acting and burnout. The group with low levels of both mindfulness and compassion experienced low levels of positive affect intensity and high levels of negative affect intensity. They also had the lowest levels of emotional clarity for self and others and genuine expression. In addition, they showed that the highest levels of surface acting, and burnout. Based on the results, the study discussed the balanced development of mindfulness and compassion to prevent burnout of professionals in the human service field, including mental health professionals. The implications and limitations of this study were further analyzed in the discussion section, including the direction for future research.

This study is a scientific approach to psychological factors such as emotional stability among various effects of forest resources. In order to carry out this study, the experiment was conducted on the subjects by setting the forest healing space as various spaces. The subjects who participated in this experiment were the students in their twenties and the average age was 22±1.25 years. The subjects were assessed for emotional words through subjective sequence evaluation in different designated forest healing spot. In addition, the emotional states that they actually perceived were measured by measuring the bio-signals to their perceived emotions. BMP, SDNN, VLF, LF, HF, Amplitude, and PPI were used for the bio-signal reaction experiment applied to this study. The results of this experiment were measured by Friedman test and Wilcoxon test for statistical analysis. n this study, 'good', 'clear', and 'uncomfortable' words were found statistically significant at the spot of forest healing space for subjective emotional vocabulary. In addition, SDNN, HF and Amplitude were statistically significant in the results of quantitative bio-signal measurement at each spot in the forest healing space. Based on the results of this study, we can suggest the application direction and strategic utilization plan of forest healing spot and forest resource utilization field. This is not only a guide for the users who use the facility through the spatial facilities and physical requirements for the emotion based forest-healing, but also can be used as a personalized emotional space design aspect.

Human communication researchers have suggested that good communication between husbands and wives is a key to a healthy marriage. Although interpersonal communication itself cannot "fix" all problems in one's marriage, the importance of good communication in a marital-relationship cannot be overstated. Regardless of its importance, the communication behavior between husbands and wives as a research topic has been paid little attention by human communication scholars in Korea. Because of the "intimacy" Korean couples who have been influenced with the long tradition of Confucius culture tend to overlook the communicative problems in a marital-relationship. Yet, it is "the belief" of the intimacy that creates much of the communicative problems in a marriage. This study is designed to explore the characteristics and transitional process of the communication behavior between Korean husbands and wives among generations. Married couples in their 20's, 30's, 40's, and 50's were surveyed with five levels of interpersonal communication process-open attitudes, problem-solving, expression, listening, and feedback. The study result reveals each generation's characteristics and transitional process of marital communication behavior from younger couples to older couples as their intimacy and "shared" lived-experience get accumulated.

한국의 고천문 자료는 삼국시대 이후 근대 조선까지 다수가 존재하여 세계적으로 드문 기록 문화를 보유하고 있으나, 한문 번역이 많이 이루어지지 않아 학술적 활용이 활발하지 못한 상태이다. 고문헌의 한문 문장 번역은 전문인력의 수작업에 의존하는 만큼 소요 시간이 길기에 투자대비 효율성이 떨어지는 편이다. 이에 최근 여러 분야에서 응용되는 인공지능의 적용을 대안으로 삼을 수 있으며, 초벌 번역 수준일지라도 자동번역기의 개발은 유용한 학술도구가 될 수 있다. 한국천문연구원은 한국정보화진흥원이 주관하는 2019년도 Information and Communication Technology 기반 공공서비스 촉진사업에 한국고전번역원과 공동 참여하여 인공신경망 기계학습이 적용된 고문헌 자동번역모델을 개발하고자 한다. 이 연구는 고천문 도메인에 특화된 인공지능 기계학습 기법으로 자동번역모델을 개발하여 이를 서비스하는 것을 목적으로 한다. 연구 방법은 크게 4가지 개발을 진행하는 것으로 나누어 볼 수 있다. 첫째, 인공지능의 학습 데이터에 해당되는 '코퍼스'를 구축하는 것이다. 이는 고문헌의 한자 원문과 한글 번역문이 쌍을 이루도록 만들어 줌으로써 학습에 최적화한 데이터를 최소 6만 개 이상 추출하는 것이다. 둘째, 추출된 학습 데이터 코퍼스를 다양한 인공지능 기계학습 기법에 적용하여 천문 분야 특수고전 도메인에 특화된 자동번역 모델을 생성하는 것이다. 셋째, 클라우드 기반에서 참여 기관별로 소장한 고문헌을 자동 번역 모델에 기반하여 도메인 특화된 모델로 도출 및 활용할 수 있는 대기관 서비스 플랫폼 구축이다. 넷째, 개발된 자동 번역기의 대국민 개방을 위해 웹과 모바일 메신저를 통해 자동 번역 서비스를 클라우드 기반으로 구축하는 것이다. 이 연구는 시스템 요구사항 분석과 정의를 바탕으로 설계가 진행 또는 일부 완료되어 구현 중에 있다. 추후 이 연구의 성능 평가는 자동번역모델 평가와 응용시스템 시험으로 나누어 진행된다. 자동번역모델은 평가용 테스트셋에 의한 자동 평가와 전문가에 의한 휴먼 평가에 따라 모델의 품질을 수치로 측정할 수 있다. 또한 응용시스템 시험은 소프트웨어 방법론의 개발 단계별 테스트를 적용한다. 이 연구를 통해 고천문 분야가 인공지능 자동번역 확산 플랫폼 시범의 첫 케이스라는 점에서 의의가 있다. 즉, 클라우드 기반으로 시스템을 구축함으로써 상대적으로 적은 초기 비용을 투자하여 활용성이 높은 한문 문장 자동 번역기라는 연구 인프라를 확보하는 첫 적용 학문 분야이다. 향후 이를 활용한 고천문 분야 학술 활동이 더욱 활발해질 것을 기대해 볼 수 있다.

The goal of this study was to examine the association between employment and depressive symptoms among older adults in Korea, including analysis of potential gender differences. Using a sample of Korean adults aged 60 years or older from the 2008(Time 2) and 2010(Time 3) national longitudinal survey data from the Korean Longitudinal Study of Ageing, we regressed measures of depressive symptoms at Time 3 on employment at Time 2 (and employment both at Time 2 and Time 3), controlling for Time 2 depressive symptoms, subjective physical health, and sociodemographic variables as well. First, there was no evidence that older adults with a job at Time 2 had significantly lower levels of depressive symptoms at Time 3 compared to their counterparts. However, multi-group analyses showed that the effect of employment at Time 2 on depression at Time 3 differed by gender. For older men, employment predicted better mental health over time. However, this was not the case for older women. As such work role provided benefits only for older men. Second, older adults with a job at both Time 2 and Time 3 reported significantly lower levels of depressive symptoms at Time 3 than older adults who did not have a job either at Time 2 or Time 3. However, only older men who were employed at both Time 2 and Time 3 reported significantly less depression than their counterparts. These findings suggest that the mental health effects of employment are contingent on gender.
