본 연구는 소비자의 감성과 관련이 높은 영향 요인과 상관관계를 조사했다. 한국의 대형 생명보험사의 콜센터에서의 음성데이터를 활용하여 고객의 긍부정 감성을 파악하였으며, 고객의 긍부정 감성은 보험서비스 해약 지표와 매우 밀접하게 연관되어 있음을 확인하였다. 따라서 대상 회사의 서비스 해약 여부 데이터를 고객 긍부정 감성의 대용 변수로 활용하고 머신러닝 기법을 적용하여 해약 고객 속성을 분석함으로써 소비자 감성 성향과 관련한 소비자의 특성을 정량화 하였다. 연구 결과, 소비자는 연령이 많은 경우, 여성, 기혼, 보유자산이 큰 경우, 소득이 낮은 경우, 계약 상담이나 신상품 제안을 자주 받는 경우, 여러 상품을 보유하고 있는 경우에 보험 서비스 이탈 가능성이 높은 것으로 나타났다. 즉, 이러한 특성의 고객은 보다 부정적인 감성 성향을 암시하고 있음을 시사한다. 본 연구의 학문적 의의는 기존의 설문조사 기반 감성 평가 접근법을 넘어 정량적 패러다임을 수용한 데 있으며, 실용적인 관점에서 국내 보험회사에 고객 성향에 대한 신뢰성 높은 정보를 제공하여 고객 유지율 관리 전략을 수립할 수 있는 지침을 제시한다. 아울러, 비즈니스, 심리학, 교육학, 사회학 등 개인의 감정 분석과 관련된 다양한 학문에 유용한 관점을 제공하고 있다. This study aimed to identify the influencing factors and correlations that are highly related to consumer emotions. Voice data from the call center of a large Korean life insurance company was utilized to ascertain the positive and negative emotions of customers. It was found that positive emotions are closely related to insurance churn indicators. Therefore, the characteristics of consumers related to their emotional tendencies were quantified by using the data on whether they canceled their services as a proxy for positive emotions and applying machine learning techniques to analyze the attributes of canceled customers. The results indicate that consumers are more likely to cancel insurance services if they are older, female, married, have large assets, have low income, receive frequent contract counseling or new product offers, and have multiple products. These characteristics are indicative of a more negative emotional disposition. The significance of this study lies in its adoption of a quantitative paradigm beyond the traditional survey-based emotion assessment approach. From a practical perspective, it provides domestic insurance companies with reliable information on customer dispositions, which can be used to inform their customer retention strategies. Furthermore, the study offers insights that can be applied across various disciplines related to the analysis of individual emotions, including business, psychology, education, and sociology.

Recently, clinical efficacies of the intraoral balancing appliance therapy have been reported by several researchers, and it has been found that there are various kinds of diseases that can be effectively applied. However, studies on cerebrovascular disease, one of the main diseases with a high mortality rate, are still poorly reported, and studies of temporomandibular joint disorder (TMD)-induced changes in brain function suggest that cerebrovascular disease is more appropriate as an adaptive disorder of the temporomandibular joint (TMJ) balancing device. In the developed countries, the importance of research on the structure and function of the brain has been recognized and spurred on the related research. In Korea, the research on brain function and cognitive disorders should have promoted more massively. In order to regain its former reputation in the Korean medicine in the field of cerebrovascular disease, it should be spurred on basic research and clinical case studies. In addition, extensive and in-depth studies including animal studies are needed to establish the basis of underlying mechanisms of the TMJ balancing therapies.

Objectives : Mori Radicis Cortex (MRC), the root epidermis of Morus alba L., has been traditionally used to treat lung-related diseases in Korean Medicine. The common of MRC is Mulberry bark Morus bark, and it`s pharmaceutical properties and taste are known as sweet and cold, and it promotes urination and reduce edema by reducing heat from the lungs and soothe asthma. In the present study, anti-apoptotic mechanism of MRC in middle cerebral artery occlusion (MCAO) model in mice. Methods : Two-hundred grams of MRC was extracted with methanol at room temperature for 5 days, and this was repeated one time. After filtration, the methanol was removed using vacuum evaporator, then stored at -20℃ until use. C57BL/6 male mice were housed in an environment with controlled humidity, temperature, and light cycle. In order to determine beneficial effects of MRC on ischemia induced brain damage, infarct volume, neurological deficit scores, activities of several apoptosis-related proteins such as caspase-8, -9, Bcl-xL in MCAO-induced brains of mice were analyzed. Mice in MRC-treated groups were orally administered 30, 100, or 300 mg/kg of body weight for three consecutive days before commencing the MCAO procedure. Results : Pre-treatment of MRC significantly reduced infarct volume in MCAO subjected mice applied with 300 ㎎/ ㎏ of MRC methanol extract, and MRC effectively inhibited Bcl-xL reduction and caspase-9 activation caused by MCAO-induced brain damage. Conclusions : MRC showed neuro-protective effects by regulating apoptosis-related protein signals, and it can be a potential candidate for the therapy of ischemia-induced brain damage.

This study aims to identity the impact of social network on the health of the rural elderly in social activities. On this study, social networks were composed of marital relations, parent-child relationship and relationship with friends, meanwhile, health was measured with the self-rated health, health behavior and social & emotional loneliness. The findings of this study could be summarized as following. First, the self-rated health was meaningly influenced by gender, the standard of living, the number of children, the contact frequency with children, the friend satisfaction. Second, the factors affecting the health behavior of the rural elderly were the presence of the education level, the standard of living, the children satisfaction, the contact frequency with friend and the friend satisfaction. Thirdly, the social & emotional loneliness had negative relations with the standard of living, the children and the friend satisfaction. Noticeably, according to hierarchical linear regression analysis, the friend satisfaction was a factor affecting the self-rated health, the health behavior and social & emotional loneliness of the rural elderly. Thus, this study suggests that the quality of social network should be important in order to improve the level of health of the rural elderly.

Purpose: The purpose of this study is to understand the actual status of fundamentals of nursing practice (FNP) education at nursing colleges, and the difficulties of FNP operation in the early stages of the COVID-19. Methods: This study used a descriptive design. Data collection was conducted from December 9, 2020 to January 31, 2021 using the self-report questionnaire method for a total of 95 nursing colleges. The questionnaire consisted of characteristics related to FNP, changes in FNP education, difficulties in operating FNP, and countermeasures in the COVID-19 situation. Results: Changes in FNP due to COVID-19 were distribution of practice places, reduction of the number of students, short-term intensive classes, and reduction of face-to-face practice. Most colleges conducted FNP face-to-face, but some schools showed that FNP was conducted non-face-to-face. The difficulties of operating FNP that instructors experienced induced concerns about a decrease in student competency due to lack of face-to-face practice and an unofficial increase in the number of teaching hours and physical demands on instructors due to the expansion of the division. Conclusion: In order to develop the capabilities of nursing students in other pandemic situations in the future, it is necessary to find systematic coping strategy to reduce the burden of FNP instructors, and to develop non-face-to-face online practice contents and consumables for online practice.
