  • Background: Alcohol is one of the most commonly used psychoactive drugs. Due to its addictive characteristics, many people struggle with the side effects of alcohol. Korean Red Ginseng (KRG) is a traditional herbal medicine that is widely used to treat various health problems. However, the effects and mechanisms of KRG in alcohol-induced responses remain unclear. Therefore, the purpose of this study was to investigate the effects of KRG in alcohol-induced responses. Methods: We investigated two aspects: alcohol-induced addictive responses and spatial working memory impairments. To determine the effects of KRG in alcohol-induced addictive responses, we performed conditioned place preference tests and withdrawal symptom observations. To assess the effects of KRG in alcohol-induced spatial working memory impairment, Y-maze, Barnes maze, and novel object recognition tests were performed using mice after repeated alcohol and KRG exposure. To investigate the potential mechanism of KRG activity, gas chromatography-mass spectrometry and western blot analysis were performed. Results: KRG-treated mice showed dose-dependent restoration of impaired spatial working memory following repeated alcohol exposure. Furthermore, withdrawal symptoms to alcohol were reduced in mice treated with KRG and alcohol. The PKA-CREB signaling pathway was activated after alcohol administration, which was reduced by KRG. However, the levels of inflammatory cytokines were increased by alcohol and decreased by KRG. Conclusion: Taken together, KRG may alleviate alcohol-induced spatial working memory impairments and addictive responses through anti-neuroinflammatory activity rather than through the PKA-CREB signaling pathway.

  • purpose: The study was done to analyze the concept of moral distress in nurses. Method: The Hybrid Model was used in this study. For the theoretical phase, nursing and other literature were reviewed to analyze attributes and develop a working definition of the concept, moral distress in nurses. For the fieldwork phase, In-depth interviews were conducted with six nurses. Results: Four higher level concepts of moral distress in nurses were found; situational, cognitive, behavioral, and emotional, and 8 subscales, negative medical behavior, negative nursing behavior, excessive economic load, irrational organization administration, internal restraints, external restraints, negative behavioral responses, and negative emotional responses. Conclusion: it is necessary to develop programs of arbitration that will lessen the moral distress in nurses working in clinical practice.

  • Bereavement is the state of loss resulting from death. Grief is the emotional response associated with loss, intense and acute sorrow resulting from loss. Complicated grief represent a pathological outcome involving social, physical, emotional, cognitive, spiritual morbidity. The common psychiatric disorders associated complicated grief or abnormal grief responses include clinical depression, anxiety disorders, alcohol abuse or other substance abuse, and dependence, psychotic disorders, and post-traumatic stress disorder (PTSD). Grief tasks involve a series of stage or phases following an important loss that gradually permit adjustment and recovery. Three phases of grief involve phase 1 (walking the edges), phase 2 (entering the depths), and phase 3 (reconnecting the world). For intervention to be effective they need to be individually tailored to abnormal grief reaction or unresolved grief reaction. Clear understandings of complicated grief, abnormal responses, factors increasing risk after bereavement will often enable us to prevent psychiatric disorders in bereaved patients.

  • The purpose of this study was to examine the effects of consumption experience on customer satisfaction and customer happiness for dessert cafe. The survey was conducted with those who have visited dessert cafes in Seoul and Kyonggi area, using a convenience sampling method. After a total of 200 responses was collected, 172 responses were included for the multiple regression analyses in order to test the hypotheses. The results are as follows. First, it was found that consumption experience did not have an effect on customer satisfaction for dessert cafes. Second, the consumption experience (diversity, symbolism, sociality, and playfulness) of dessert cafe significantly impacted customer happiness. As a conclusion, consumption experience at dessert cafes has increased customer happiness by improving the psychological gratification rather than cognitive satisfaction.

  • This paper describes the categorical effects of pitch accent contrasts in a mimicry task. It focuses, specifically, on examining how fundamental frequency (f0) variation reflects phonological contrasts from speakers of two distinct varieties of Korean (i.e., North Kyungsang and South Cholla). The results showed that, in a mimicry task using synthetic speech continua, there was a categorical effect in f0 peak timing for North Kyungsang speakers, but the timing of f0 peaks and valleys in the responses of South Cholla speakers was more variable, presenting a gradient or non-categorical effect. Evidence of categorical effects was represented as the shift of f0 peak times along an acoustic continuum for North Kyungsang speakers. The range for the shift of f0 valley times was much narrower, compared to that of f0 peak times. The degree of a shift near the middle of the continuum showed variability across individual mimicry responses. However, the categorical structure in mimicry responses regarding the clustering of f0 peak points was more significant for North Kyungsang speakers than for South Cholla speakers. Additionally, the finding of the current study implies that the location of f0 peak times depends on individuals' imitative (or cognitive) abilities.

  • Purpose: The purpose of this study was to understand the impact of long- and short-term energy drinks on anxiety-like, depressionlike, and cognitive behavior in adolescent rats. Methods: Adolescent rats (age six weeks) were randomly classified into a control group (CON), a long-term administration group (LT), and a short-term administration group (ST). The LT group was orally administered 1.5 mL/100 g (body weight) of energy drink twice daily for 14 days, the ST group was orally administered for one day, and the control group applied the same amount of normal saline. Later, an open-field test, a forced swim test, novel object recognition test, and an 8-arm radial maze test was conducted to assess the rats' anxiety, depression, and cognitive function. Results: There were different effects in the long- and short-term groups of energy drink administration. In the LT group, anxiety- and depressive-like behavior increased because of increased movement in the side corner and decrease of immobility time. Also, the time to explore novel objects decreased, and the number of correct responses was reduced, indicating a learning and memory function disorder. However, the ST group was not different from the control group. Conclusion: These results indicate that long-term consumption of energy drinks can increase anxiety-like, depression-like behavior, and this can lead to decrease in learning and memory functions. Thus, nurse and health care providers should understand the impact of energy drink consumption in adolescence to provide appropriate practices and education.

  • Consumption has generally become more fragmented, hedonic and individual specific, satisfying not only functional but also emotional needs. In parallel, customer satisfaction is now thought to be both a cognitive and affective response, and the closely related concept of job satisfaction is commonly seen as an emotional reaction. The reasoning within quality management does, however, still lean heavily toward cognitive judgements (i.e. performance ratings), the emotional component clearly being under explored. Further, performance variables have shown not to be significant in predicting satisfaction for certain 'experience products', the effect fully mediated by emotions. As a consequence a cognitive judgement based quality concept has lost its ability to predict satisfaction, which clearly contradicts with the modem quality definition, stressing quality as the ability to satisfy the customer. Emotions have however entered the quality discourse and it has been proposed that having customers that are merely feeling satisfied will not suffice. Instead, there has been a plethora of executive exhortations in the trade press calling on business to 'delight the customer'. Strategies for doing so have however usually been imprecise and unclear, and the different drivers of delight and satisfaction are not well explored. This paper aims to complement the previous cognitive dominance by exploring the multiple emotional responses involved in customer satisfaction. A conclusion being that we currently are measuring something, in terms of satisfied, that is more or less independent of what we aim for, in terms of delight. It is also most likely that - depending on the situation, product, and person - other positive and negative emotions are more important outcomes of purchase and usage than merely satisfaction. It is questioned whether a single, summary response such as satisfaction is feasible or even desirable.
