The pandemic of COVID-19 also affected performing arts business and stimulated 'Untact' performances, which means online streaming of the shows including real-time streaming. This study sought to examine factors to the consumers' acceptance. The research framework was based on the VAM, a revised model of TAM for the ICT products and services. For the research, consumer survey was conducted, where ndependent variables are perceived usefulness, pleasure, technicalty and innovation resistance, and dependent variables are percieved value and acceptance. Smart PLS was used to test the hypothesis. The result shows that the significant factors were percieved usefulness(+), pleasure(+) and innovation resistance(-). The percieved technicalty was not significant, the major reason would be that the digital devices and the internet technology are percieved a commodity these days in Korea. Percieved value was significant factor to acceptance. This study is meaningful because it is about the new phenomenon of 'untact' performance through the VAM methodology and it examined the significant factors to the attitude from the perspective of benefits and costs. There is limit that this study didn't consider old peoples' attitude. It is the reason that the continuous researches are necessary.

Purpose: This study examined the factors that may affect the growth status of preterm infants. Methods: This study included 91 preterm infants born at <37 weeks of gestation (22.9-36.9 weeks of gestation), including 48 (52.7%) males and 43 (47.3%) females. Diet-related data were collected through parental questionnaires, and growth-related data, such as height and weight, were collected through the hospital medical records. Results: No significant difference in weight and growth was observed between early and late preterm infants. On the other hand, smaller averages of all weight z-score (recent weight at 40 weeks of gestation) included lower birth weight, height, and head circumference. On the other hand, infants' birth weight, height, and head circumference in the weight z-score of <0 (<50% in the age-weight growth chart) was smaller than those in the weight z-score of ≥0. Furthermore, neonatal intensive care unit (NICU) hospitalization period and NICU discharge were shorter with growth cessation age in weight z-score of <0. The weight growth velocity was associated with gestational age, birth weight, and medical treatment in the NICU. Thus, parents of preterm infants with low growth rates prefer more community care services for their children. Conclusion: Birth weight, age of preterm infants, and medical treatment in the NICU were factors related to early birth weight growth. Following NICU discharge, poor intake and intake issues were associated with poor growth after 40 weeks of gestation. Therefore, monitoring the growth of preterm infants requires continuous active involvement and supports for growth-promoting factors after NICU discharge.

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.

The Beopmaru, Supreme Court Library of Korea, the national library of the judiciary, is the only one that can help reduce the justice gap and increase access to justice by allowing the general public and legal experts to read and circulate. Accordingly, this study identified user satisfaction with the Beopmaru public service through surveys and interviews and derived ways to improve the service. User satisfaction was in the following order out of 5 points: response of librarian 4.62 points, facility management 4.48 points, and cultural programs such as events and lectures 4.33 points. Satisfaction with collection composition was the lowest at 3.97 points. This appears to be because collection composition is where legal expertise has the greatest impact on satisfaction. As satisfaction with the collection composition was the lowest, collection expansion was the highest at 44%(114 people) as a service that Beopmaru needs to strengthen in the future, and a balanced collection of books according to the user base is needed in the future. Based on this, improvement measures were proposed to include dualizing the Beopmaru reading space and services for the general public and legal experts, strengthening its identity as a legal library, improving the system, and strengthening publicity and response of librarian. If the Beopmaru public service is successfully established through continuous research in the library and information community, it will be possible to improve the service quality of the law library industry as a whole, including law libraries, and increase user satisfaction.

Focusing on Gyeonggi Library, which is preparing Metaverse services using resident participatory budgets, we deduced the role of Metaverse suitable for metropolitan representative libraries, conducting a preliminary study and analyzing various informational resources. Subsequently, we presented a collaborative content construction and service model primarily centered around the metropolitan representative library. We conducted a survey targeting on-site librarians from metropolitan representative libraries, as well as various libraries across Gyeonggi Province and the entire nation. Through this survey, we extracted insights into the Metaverse role, content possibilities, and considerations for seamless cooperation within the scope of the metropolitan representative library. Based on the opinions of surveyed librarians, it was evident that the role of the metropolitan representative library's Metaverse should function as a tool for continuous utilization of library resources and serve as a space for the entire local community. Approximately three-fourths of the respondents expressed willingness to participate in collaborative content development. However, concerns were raised about human resource limitations, budget constraints, and excessive workloads as potential obstacles to participation. This highlighted the need for systematic support from the metropolitan representative library to address these concerns.

Photosynthetically active radiation flux density (PPFD) and daily light integral (DLI) values related to plant photosynthesis were obtained using the sunlight time and insolation data points in the agricultural weather sensor data for Jinan-gun, Jeollabuk-do, Korea from 2016 to 2020. The objective was to optimize the photo-environmental conditions for cultivating ginseng. The range of average monthly sunshine duration was 395.5-664.1 min, with the longest duration observed in June. The range of average annual accumulated daily insolation was 11.98-17.65 MJ·m^-2. The range of average daily external DLI calculated from the insolation and solar time data was 22.3-36.1 mol·m^-2·d^-1, and the annual cumulative DLI was 8,156-13,175 mol·m^-2·d^-1. Both the insolation and DLI values were the highest in 2016 and lowest in 2020. Based on the PPFD required for ginseng growth (111-185 µmol·m^-2·s^-1), the monthly average daily DLI and monthly cumulative DLI were 3.51-5.87 and 82-228 mol·m^-2·d^-1, respectively. The range of five-year average value for the external monthly cumulative DLI was 298-1,459 mol·m^-2·d^-1, and the monthly cumulative DLI values when a black double shading film and blue-white shading film were applied were 101-496 and 36-175 mol·m^-2·d^-1, respectively. A comparative analysis of DLI values indicated that shading was required to ginseng growth throughout the year under natural light. When the black double shading film was used, shading was required from March to October. When the blue-white shading film was applied from April to August, (i.e., the period with active ginseng growth) the appropriate DLI for ginseng growth could be continuously maintained. Regional weather differences due to climate change are gradually increasing, and even in one region, monthly and cumulative DLI values are different every year. Therefore, in order to implement a precise agricultural environment for ginseng cultivation, precise analysis and continuous research using agricultural weather sensor big data is required.

The purpose of this study is to improve the private utilization of military welfare facilities that are aging or underutilized in urban areas. It also aims to develop ways to strengthen cooperative win-win strategies between the military and local communities. The use of military welfare facilities by the private sector refers to activities where the private sector generates additional benefits or added value by allowing the use of these facilities, including both private use and improvements to facilities or development of land through private sector involvement. From the perspective of the city and the locals, military welfare facilities are perceived as resident-friendly and excellent urban resources that can promote reciprocal satisfaction between the military and local communities. From the perspective of the military, military welfare facilities are important for enhancing the welfare of military personnel. However, they often face limitations in providing various welfare services due to the aging of facilities and limited operations with a single purpose. The improvement of private utilization of military welfare facilities will bring diverse reciprocal benefits to the military, the city, and the locals. Above all, improving the private utilization of military welfare facilities can help the military and local communities jointly address diverse urban issues. To establish cooperative governance and find flexible and diverse development strategies that can promote the welfare of the military and enhance the quality of life for the locals, it is important that both the military and local communities make continuous efforts.

The purpose of this study is to explore the process of multicultural perception change of university students who have participated in multicultural mentoring. From May to December of the year 2015, the researcher conducted continuous e-mail interviews as well as in-depth interviews with mentors who participated in multicultural mentoring at I university. The interview contents were transcribed and comparative analysis was done. The result of the study is as follows. The process of multicultural perception change of mentors were discovered to be change in stereotypes, prejudice and ideas on multiculture, difference detection and social desire. They realized that stereotypes and prejudice were the errors of generalization due to their ideas on multiculture which were developed through media. Through mentoring activities the mentors reflected on the inherent negative ideas on multiculture, thus changing their ideas and thoughts. Also, the difference detection acknowledged cultural diversity along with the understanding of the cultural environment of mentees. Social desire expressed their wish for the change of perception in the cultures of others along with the positive change of multicultural perception through mentees. Thus, it was discovered that multicultural mentoring activities are sufficient prerequisites to change the social perception of multiculture from personal interest.

Today, the world is experiencing a variety of natural disasters due to the extreme weather. Drought that occurred throughout Southeast Asia from February to May 2016 is also a form of abnormal climate. As a result of this drought, five countries, including Cambodia, Thailand, Vietnam, Laos and Myanmar, faced food shortages, food shortages, as well as rice yields for export. In this study, remote sensing technique was applied to the vicinity of Tonlé Sap, the largest lake in Southeast Asia, to quantitatively analyze the damage caused by drought. As a result, the change of land cover caused a drastic decrease in the water system (132.582㎢) and greenery (706.937㎢) in February 2016, and the reduced water system and greenery changed to dry land and paddy field. It was also found that the temperature rise of 6℃ ~ 8 ℃ compared to the previous year due to the drought from February to April 2016 due to the change of the surface temperature. And it was found that the function of the lake was deteriorated in April due to continuous drought.
