Despite the growing importance of video-based social media content, such as vlogs, as a marketing tool in the travel industry, there is limited research on the characteristics that enhance engagement among potential travelers. This study explores the influence of emotional valence in YouTube travel content on viewer engagement, specifically likes and comments. We analyzed 4,619 travel-related YouTube videos from eight popular tourist cities. Using negative binomial regression analysis, we found that both positive and negative emotions significantly influence the number of likes received. Videos with higher positive emotions as well as negative emotions receive more likes. However, when it comes to the number of comments, only negative emotions showed a significant positive influence, while positive emotions had no significant impact. These findings offer valuable insights for marketers seeking to optimize engagement strategies on YouTube, considering the unique nature of travel products. Further research into the effects of specific emotions on engagement is warranted to improve marketing strategies. This study highlights the powerful impact of emotions on viewer engagement in the context of social media, particularly on YouTube.

The gender equality consciousness of public service workers is important since it is not only existed as attitudes and behaviors but also utilized as a policy tool. Therefore, it should be developed to improve practical abilities which enable them to analyze and integrate their own works based on gender perspective. This study examined the experiences and attitudes toward gender egalitarianism education, based on a survey of public service workers in Daejeon city(699 men and 457 women). The results can be used for desirable changes of gender egalitarianism education. We can see that the will of men to participate in the gender egalitarianism education is lower compared to it of women. To expand gender egalitarianism education, the motivation and legislation for participating in education, and the development of various education programs according to gender, age and positions are needed.

In this study, the smart docent interface provided at 25 exhibition halls at domestic and foreign were compared and analyzed based on affordance. Heuristic evaluation techniques were adopted, centered on a small number of experienced people, and six research participants were selected based on Jacob Nielsen's guidelines that five to eight people per set of research can achieve sufficient results. As a result of comparative analysis of affordance, smart docent used in the Oriental showed a higher average value than smart docent used in the Western, but a lower value for sensory affordance alone. In addition, the categories were subdivided to derive the affordance values for each country, and a singularity was found that the sensory affordance of smart docents used in the United States represents the highest value compared to other countries. In conclusion, this study was able to compare the four affordances of smart docents used in domestic and foreign exhibition halls while presenting directions for future behavioral improvement, which could provide practical implication for smart docent interface design and exhibition hall service strategies.

IT기술의 발전과 스마트기기의 대중화로 인한 정보통신기술의 눈부신 발전으로 온라인 플랫폼을 통한 식품구매 비중이 급격히 증가하여 온·오프라인의 경계를 없어지고 있다. 더군다나 COVID-19 팬데믹은 반조리식품, 밀키트 등 홈쿡(Home-cook) 온라인시장을 급격히 확산시키며 소비자 구매추세를 오프라인에서 온라인으로 완전히 바꿔놓는 전환점이 되었다. 이런 트랜드를 반영하듯 다양한 온라인 식자재 이커머스 플랫폼의 출현하면서 브랜드마다 각각의 차별점을 내세우고 있으나 경쟁은 치열해지고 차별화는 더욱 어려운 게 현실이다. 이는 기업이 소비자에게 일방향으로 정보 또는 상품 및 서비스를 제공 하는 수직적 관계가 아닌, 수평적 쌍방향 관계로의 발전으로 이어져 브랜드가 가지고 있는 가치에 대해 보다 정직하게 보여주어야 소비자의 신뢰를 얻을 수 있게 되었다(Kotler, 2017). 또한, 과거에 소비자들의 만족도가 높았던 서비스도 현재 환경에서는 소비자의 니즈를 충족시키지 못하는 경우가 증가하고 있다(조윤오, 2018). 이는 서비스에 대한 소비자의 기대와 니즈가 지속적으로 변화하고 있다는 것을 의미하며, 이에 따라 기업은 소비자들의 새로운 요구를 만족시키기 위하여 다양한 서비스를 개발 및 제공하는 것이 중요하다고 사료된다(김광재 등, 2011). 이미 높은 인지도를 가진 플랫폼일지라도 지속가능한 우위를 선점하기 어려운 상황에서 온라인 플랫폼에 대한 소비자의 긍정적인 태도와 재구매를 유도하기 위해 제품 본질 뿐 아니라 서비스 차별화를 꾀하고 있고 차별화된 포지션을 차지하기 위해 온라인 플랫폼에 대한 소비자 인식과 서비스 품질 요인을 측정하여 고객이 중시하는 요인에 집중하는 것이 필요하다. 이에 본 연구는 온라인 플랫폼을 통해 식자재를 구매하는 소비자의 꾸준한 방문과 구매를 유인하기 위해 어떤 변수의 영향력을 높여야 소비자 재구매의도를 증가시킬 수 있는지 방법을 모색하고 온라인 플랫폼 기업 및 스타트업의 경영전략 마련에 목적이 있다. 이를 위해 식자재 구매 플랫폼 품질속성, 서비스품질 정도,, 충성도의 전반적인 영향관계를 파악하는 연구 과제를 설정하고, 식자재 이커머스 온라인 플랫폼 이용 전반에 대한 평가를 실시할 예정이다. 이러한 과정을 통해 도출된 결과는 식자재 이커머스 플랫폼 운영 전략을 세우는데 유용한 자료가 될 것이라 기대하며, 기존의 온라인 식품구매 플랫폼의 서비스품질 요인과 소비자 행동 간의 관계를 설명하는 것과는 다른 새로운 시사점을 제공할 수 있다는 측면에서 의미 있는 연구가 될 것이다. 또한, 다양한 산업에서의 플랫폼 비지니스 모델 적용을 위한 전략 수립을 하는 데에 필요한 기초자료를 마련하고자 한다.

The current study was conducted to evaluate beneficial effects of a new formula (CWC-9) using four traditional Oriental medicinal herbs, Cynanchum wilfordii, Rehmannia glutinosa, Polygala tenuifolia, and Acorus gramineus, on hippocampal cells and memory function. To examine the neuroprotective effects of a new four-herb extract, cell viability, cytotoxicity, and reactive oxygen species (ROS) assays were performed in HT22 cells and behavioral tests (Morris water maze and passive avoidance retention), Western blot, and immunohistochemistry were performed in a mouse model of focal cerebral ischemia. In HT22 hippocampal cells, pretreatment with CWC-9 resulted in significantly reduced glutamate-induced cell death with suppression of ROS accumulation caused by glutamate. In a mouse model of focal cerebral ischemia, we observed significant improvement of spatial and short-term memory function by treatment with CWC-9. Phosphorylated p38 mitogen-activated protein kinases (MAPK) in hippocampus of ischemic mice were decreased by treatment with CWC-9, but phosphorylated phosphatidylinositol-3 kinase (PI3K) and cAMP response element binding protein (CREB) were significantly enhanced. By immunohistochemical analysis, we confirmed higher expression of phosphorylation of CREB in the hippocampal neurons of CWC-9 treated mice. These results suggest that new multi-herb formula CWC-9 mainly exerted beneficial effects on cognitive function through regulation of neuro-protective signaling pathways associated with CREB.

This paper reviewed the awareness of the military personnel as to job training executed in the Korean army and to figure out how this job training affects the military morale and organizational performance. For this study, 220 volunteers were surveyed and analyzed using the SPSS statistical package program. As a result of the analysis, the following conclusion could be drawn. First, in the result of analysis on the status of-the-job education, the educational time marked 49.5% for 2-4 hours, the education of job capability development marked 77.7% for the content of education, and the charged instructor of job training marked 56.8% for the education department. Second, in the result of an analysis of job training on military morale, the recognition level of behavioral dimension increased with increasing participants' independence, and the satisfaction with the cognitive dimension increased with increasing participants' independence, continuous learning culture, and educational level. Moreover, the emotional score increased with increasing learning culture and educational level. Third, an analysis of the influences of job training on the organizational performance showed thatthe degree of job satisfaction increased with increasing learning motive and learning culture, and the organizational commitment increased with increasing instructor's quality. Fourth, regarding the influences of military morale upon the organizational performance, the higher job satisfaction and organizational commitment increased with increasing behavioral, cognitive, and emotional dimension. Therefore, military morale improves organizational performance and is an important factor in inducing individual development.

Evidence suggests that even low-dose irradiation can lead to progressive cognitive decline and memory deficits, which implicates, in part, hippocampal dysfunction in both humans and experimental animals. This study examined whether diethyldithiocarbamate (DDC) could attenuate memory impairment, using passive avoidance and object recognition test, and suppression of hippocampal neurogenesis, using the TUNEL assay and immunohistochemical detection with markers of neurogenesis (Kiel 67 (Ki-67) and doublecortin (DCX)) in adult mice treated with gamma radiation (0.5 or 2 Gy). DDC was administered intraperitonially at a dosage of 1,000 $mg{\cdot}kg^{-1}$ of body weight at 30 min. before irradiation. In passive avoidance and object recognition memory test, the mice, trained for 1 day after acute irradiation (2 Gy) showed significant memory deficits compared with the sham controls. The number of TUNEL-positive apoptotic nuclei in the dentate gyrus (DG) was increased 12 h after irradiation. In addition, the number of Ki-67- and DCX-positive cells were significantly decreased. DDC treatment prior to irradiation attenuated the memory defect, and blocked the apoptotic death. DDC may attenuate memory defect in a relatively low-dose exposure of radiation in adult mice, possibly by inhibiting a detrimental effect of irradiation on hippocampal neurogenesis.

Plants release a large variety of volatile organic compounds (VOCs) into the surrounding atmosphere. Floral volatile compounds (FVCs) emitted from many plants is the critical factors for pollinator attraction and defense for adaptation in environments. Recent studies indicate that the chemical components contributing to FVCs play an important role in the honeybee attractiveness to flowers. Olfactory signals are rapidly learned, indicating that foraging behavior results from the association of plant chemicals acting as chemosensory cues for the bees. Solid phase microextraction(SPME)-GC/MS method was applied to analyze the chemical composition of FVCs according to the different species of Robinia spp. The abundant compounds identified in R. pseudoacacia were (Z)-β-ocimene (34.86%) and linalool (35.47%). Those of the tetraploid R. pseudoacacia were (Z)-β-ocimene (35.42%) and α-Farnesene (33.94%). The volatiles of R. margarettae 'Pink Cascade' comprised an abundance of (Z)-β-ocimene (42.73%), (E)-4,8-Dimethylnona-1,3,7-triene (37.23%). Differences in FVCs of the different species of Robinia spp. are discussed in light of biochemical constraints on volatile chemical synthesis and of the role of flower scent in ecology of pollination.
