  • Alcohol content, which is an important standard for Takju, a traditional multiple parallel fermentation liquor called makgeolli, is a factor that can affect the flavor. For alcohol content analysis, the distillation/hydrometry technique is mainly used. In this study, we analyzed the alcohol content of 14 commercially available Takju by the distillation/hydrometry technique and the improved GC method, respectively, after verifying the reliability of improved GC method. The precision and accuracy of the GC method were satisfactory, and LOQ and LOD were evaluated as 0.5% and 0.1% of ethanol contents, respectively. Among the three Takju exceeding the labelled alcohol content ±1, one Takju was quantitated as alcohol content 9.9% (by GC method) and 10.1% (distillation/hydrometry technique) exceeding labelled 6.0%. It was within the analytical error range of alcohol content for other two Takju, where the alcohol contents were exceeded -1.1%. The average precision (%RSD) of 14 Takju analyzed by the distillation/hydrometry technique (36.2%) and the GC method (12.8%), confirming that the GC method was better than the other. The improved GC method was evaluated to be effective in managing and improving the alcohol content standard of Takju with the wide range of alcohol content.

  • Professional baseball is one of the spectator sports that has been loved for a long time by the citizens as a recreational activity since its establishment in 1982, and has been playing pivotal role as a national sport. However, there has been decline in the number of audiences since 2019. Hence, this research paper aimed to provide strategic direction for planning and improvement of professional baseball stadiums by applying the concept of servicescape. In this research, five key factors of servicescape that affects players performance and the level of immersion of spectators were derived through literature review, and based on these key factors, case study analysis were carried out for 51 domestic and foreign baseball stadiums while focusing on the factors derived. Domestic baseball stadiums highly concentrate on spectatorship without effectively responding to change in spectators demand and its effective use of space rather than baseball games. As in foreign cases, it is critical to modify mangement process and planning direction, and improve policies while perceiving baseball stadium as recreational and cultural space.

  • This study attempted to analyze the achievement criteria of the 2015 special curriculum middle school physical education curriculum based on Bloom's new education goal taxonomy. To this end, 184 sentences based on the common curriculum and basic curriculum achievement standards of the relevant curriculum were analyzed into a total of 24 combinations of 4 dimensions of Bloom's new education goal taxonomy and 6 dimensions of cognitive courses. The results of the study are as follows. First, in the case of the special curriculum physical education and middle school achievement standards, unlike the analysis of the basic curriculum of elementary schools shown in previous studies, the 'procedural knowledge-applying' combination was the most common, and it was confirmed that there was a hierarchy by school level. In addition, the dimensions of knowledge and cognitive processes were relatively diverse, confirming the key points of physical education and middle school classes for disabled students. Second, in the case of the common curriculum among the lower curriculum, knowledge and cognitive process dimensions were relatively diverse except for cognitive process dimensions such as 'remember', and higher knowledge and cognitive process dimensions such as 'metacognitive knowledge' and 'creative'. Third, in the case of the basic curriculum among the lower curriculum, the 'procedural knowledge-applying' combination was excessively concentrated at 60.7%, which was analyzed to require improvementsary.

  • The purpose of this study is to analyze the success and failure factors of the Seoul Garden show to redefine the purpose and goal of the Seoul Garden show in the future, and to create a foundation for the Seoul Metropolitan Government to contribute to the popularization and spread of garden culture and improvement of emotional life. In order to achieve the above purpose, a survey was conducted on two groups of the general public and exhibition participants. The contents of the survey include identifying satisfaction factors and problems with the Seoul Garden show, and establishing the direction of the Seoul Garden show. As for the factors of success, the number of writers was the highest, and the improvements were overall for each element of the Seoul Garden show, but mainly for industrial exhibitions, rest areas, and publicity. In addition, the Seoul Garden show should be held in the old park with the aim of spreading, popularizing, and living the garden culture, and many gardens should be created around the artist's garden. The Seoul Garden show is contributing to society in many ways, and there are some improvements, but considering the high willingness to revisit the Seoul Garden show, it can be said that the Seoul Garden show so far is valuable enough.

  • This study was conducted to confirm the differences in nursing process competence, critical thinking disposition, and education satisfaction between clinical practicum and school practicum in the prolonged COVID19 pandemic. As an inequality control post-hoc design study, 55 students who agreed to participate in the study among the third year of nursing college students who took adult nursing practice were targeted. Data were collected by classifying the students who participated in the school practicum into the experimental group(N=29) and the students who participated in the clinical practicum into the control group(N=26). The collected data were analyzed using SPSS/WIN 22.0 program. As a result of the study, there was no significant difference in nursing process competence and critical thinking disposition between the two groups. However, in the control group, overall satisfaction with education (t=-9.82, p=.040) and recommendations to other students (t=-1.88, p<.001) were found to be significantly higher. Although it was not possible to confirm the difference between the effects of clinical practicum and school practicum as a result of the study, the significance of the study could be found in that there was no difference. In line with the post-corona era, future research on the development of a practicum program consisting of various contents, teaching methods, and practice to achieve the goal of practicum and analysis of the effectiveness of the program is suggested.

  • Due to the so-called COVID-19 pandemic, railway service management has also faced an unprecedented situation over the past. This study conducted a survey of customers using high-speed railways during the COVID-19 pandemic to explore the impact of infectious diseases on the railway service customer experience. As a result, customer satisfaction and loyalty increase as customers are more aware of the quarantine-related services provided by railway operators. The moderating role of customer's COVID-19 risk perception was examined as well because there are individual differences in the level of thinking dangerously about Covid-19. As a result, the perceived level of the service's quarantine-related services has a significant impact on customer satisfaction when the customer's risk perception of Covid-19 is at an appropriate level, but its impact is relatively weak when the customer's risk perception is significantly high. Eventually, only the complete extinction of COVID-19 risk will bring a complete recovery to the service industry. Nevertheless, during the epidemic period, it was confirmed that the main service characteristics are that the service operator thoroughly conducts quarantine activities and faithfully communicates with customers.

  • Credit transactions are used as a means of price discrimination from competitors in order for suppliers to increase customer demand. In particular, in the case of a two-stage supply chain consisting of a supplier, a retailer, and a customer, the deferral of payment for goods allowed by the supplier is a means of reducing the inventory investment cost of the retailer. Retailers have the opportunity to discount the selling price while anticipating an increase in end-customer demand through the reduction of the inventory investment cost. In view of the fact that such trade credit is provided for the purpose of increasing demand as a means of discrimination from competitors, it may be more general that the credit transaction period is allowed flexibly according to the transaction volume. In particular, in the case of deteriorating products, the credit transaction period given according to the order volume is a factor that increases the order volume of the retailer, but product deterioration can be a limiting factor in the increase in the order volume. The deterioration rate actually plays an important role in determining the inventory policy of the retailer. Therefore, in this paper, the effect of such deterioration rate on the inventory policy of retailer is analyzed.

  • The term environmental, social and governance (ESG) was first used in the 2003 United Nations Environmental Programme Finance Initiative (UNEP FI). Among the three areas of ESG, environment refers to the impact of companies on the environment. Environmental factors address climate change policies and attempts to reduce emissions, waste and natural resource consumption. Social factors refer to the direction in which a company can improve the social impact of stakeholder includes employees, customers, communities, and governments involved in direct or indirect interaction with the organization itself and the company. Governance factors refer to stakeholders who make major decisions, the composition of the board of directors, their diversity and independence, and the internal policies that set limits and expectations for decision-making. Research related to ESG management is part of corporate social responsibility, sustainability, corporate or financial performance, and social responsibility investment. Through case studies and data-based empirical studies, it was confirmed that ESG management companies had positive results for most of the ESG related fields. Through literature analysis of domestic and international ESG history, introduction background, and management performance, this paper presents theoretical, practical implications by confirming that ESG's introduction and operation strategies are strong competitive strategies that directly affect corporate growth by creating attractive factors.

  • The purpose of this study was to evaluate the effects of the non-pharmacological intervention on depressive symptoms in the older adults with mild cognitive impairment. A total of 1,147 studies were retrieved from PubMed, CINAHL, PsycINFO, Science direct, KISS, RISS, and DBPia. Twenty-one studies which met the criteria were selected and the quality assessment was conducted independently by two investigators. The effect size of non-pharmacological intervention was estimated using Comprehensive Meta-Analysis 3.0. The overall effect size turned out to be the medium effect size (Hedges' g=-0.68, 95% CI=-1.01~-0.36). As a result of the subgroup analysis, the intervention type was statistically significant. The effect size of cognitive intervention (Hedges' g=-1.03, 95% CI=-1.43~-0.61) and multi component intervention (Hedges' g=-0.97, 95% CI=-1.63~-0.33) was greater than excise intervention (Hedges' g=-0.53, 95% CI=-1.16~0.03). This study shows that non-pharmacological intervention was also effective in reducing depressive symptoms in the older adults with mild cognitive impairment. Based on the research results, it is expected that various non-pharmacological intervention studies will be attempted to improve cognitive function and depressive symptoms of the older adults with mild cognitive impairment.

  • This research compares and analyzes evacuation time depending on the change in stair width in case of fire at Goshiwons. For this, a simulation has been conducted based on possible evacuation time according to the calculation method for the number of people admittable to a specific target for fire fighting equipped with accommodation. Currently, Gosiwon, which is classified as an accommodation facility (a total floor area of 500 m2 or more), uses blind spots prescribed by the Fire Services Act, Building Act, and Parking Act to build a high-rise building on a small area of land, and most Gosiwon is transformed into a modified accommodation. This is in line with the owner's operating profit, so it is expected to show a continuous increase. Securing the golden time of Gosiwon evacuation time is the last bastion of Gosiwon residents who belong to the economically disadvantaged in our society, and we hope this study will serve as a starting point for discussions on revising related laws and regulations to establish a social safety net As a result of the evacuation simulation analysis, the evacuation time was the least when the width of the group and the evacuation stairs were expanded to 200cm, and the evacuation time of the existing building was reduced by up to 166.3 seconds by comparing 648.4 seconds and scenario 6. This analysis can be meaningful, in that the width of the evacuation stairs revision of related laws and regulations for the safety of multiplex available premises.
