This paper, based on "Minhwa Chaekgeori" paintings from the collection of the National Museum of Korea, identifies and discusses fourteen similar works in domestic and international collections as products of the Seokdang workshop. First, the relevant paintings are identified as products of the workshop known as Seokdang (石堂, literally "stone hall") by the workshop's seal that is stamped on them. Second, analysis of the iconography indicates that the paintings were likely produced in the 1920s. Third, research on certain geographic names and addresses associated with this group of paintings suggests that they might not have been separately commissioned, but are rather examples of partially "ready-made" paintings. Fourth, the paper discusses how the designs of various cultural products in these paintings reflects contemporaneous changes in Korea's diplomatic and commercial relations, i.e., the decline of relations with China and rise of relations with the United States and Europe. Finally, a comparison of the Seokdang chaekgeori paintings with the popular chaekgeori paintings produced by Yi Hyeongrok and Yi Deokyeong in the early twentieth century provides important implications for the succession of tradition and innovation in visual culture.

This study examined the effect of the industrial nursing practical education program applying online collaborative learning on perceived motivation, problem-solving ability, and communication ability of nursing students in COVID-19 period. The study was carried out according a non-equivalent control group pretest-posttest design. The study subjects were 35 nursing college students from K City. Data collection was from October 19 to November 12, 2020. Collected data were analyzed using IBM SPSS 22.0 with the 𝑥² test, Fisher's exact test, independent t-test, Mann-Whitney U test. The experimental group had significantly different perceived motivation, and problem-solving ability in comparison to the control group. This suggests that the industrial nursing practical education program applying online collaborative learning in the COVID-19 period can be applied as a way to increase nursing students' perceived motivation, and problem-solving ability.

Purpose: The purpose of this study was to analyze the trends and characteristics of infection-related patient safety incident reporting before and during the coronavirus disease 2019 (COVID-19) pandemic in Korea, and to provide basic data for preventing infection-related patient safety incidents and improving their management. Methods: A cross-sectional analysis of secondary national data (Patient Safety Reporting Data) was conducted. In total, 517 infection-related patient safety incidents reported from 2018 to 2021 were analyzed. Changes in the number of reports before and during the COVID-19 pandemic and differences in variables related to infection-related patient safety incidents were analyzed using the chi-square test and independent t-test in SPSS 29.0. Results: This study found that infection-related patient safety incidents decreased during the COVID-19 pandemic compared to before the pandemic. Furthermore, incident-related characteristics, such as the type of healthcare organization, severity of harm, and post-incident actions, changed during the COVID-19 pandemic. Conclusion: The many changes in the infection control system and practices during the COVID-19 pandemic may have contributed to a decrease in the reporting of infection-related patient safety incidents. It is hoped that longitudinal studies on patient safety incidents related to the pandemic and analytical studies on factors influencing patient safety incidents will continue to be conducted to prevent and improve patient safety incidents.

Purpose: The purpose of this study was to identify the effects of infection control performance, infection control fatigue, and social support on the burnout of nurses working at National Safe Hospitals during the coronavirus disease (COVID-19) pandemic, and to use that data to suggest methods to reduce burnout among nurses. Methods: From June 30 to September 30, 2021, data were collected from 144 nurses who both consented to participate in the study and had worked for more than six months in National Safe Hospitals with 300 or more beds in the Gyeonggi-do Province in Korea. Data were analyzed using multiple regression analysis. Results: The factors affecting nurses' burnout at National Safe Hospitals during the COVID-19 pandemic were found to be infection control fatigue (β=.60, p<.001) and social support (β=-.27, p<.001). The explanatory power of these factors was 37.0%. Conclusion: Nurses' burnout at National Safe Hospitals was found to be at a moderate level. Burnout should be reduced through human, material, and administrative support, all of which can reduce infection-control fatigue. It is also necessary to develop both a non-face-to-face social-support-reinforcement program, considering restrictions mandated by infectious-disease pandemics, and a long-term intervention strategy to prevent burnout.

To monitor newly emerged influenza virus variants and to investigate the prevalence pattern, our laboratory performed isolation of the viruses from surveillance sentinel hospitals. In the present study, we analysed influenza A/H1N1, A/H3N2, B viruses isolated in Busan during the 2006/07 and 2007/08 seasons by sequence analysis of the hemagglutinin (HA1 subunit) and neuraminidase (NA) genes. The isolates studied here were selected by the stratified random sample method from a total of 277 isolates, in which 15 were A/H1N1, 16 were A/H3N2 and 29 were B. Based on the phylogenetic tree, the HA1 gene showed that A/H1N1 isolates had a 96.7% to 97.7% homology with the A/Brisbane/59/2007, A/H3N2 isolates had a 98.4% to 99.7% homology with the A/Brisbane/10/2007, and B isolates had a 96.5% to 99.7% homology with the B/Florida/4/2006(Yamagata lineage), which are all the vaccine strains for the Northern Hemisphere in 2008~2009 season. In the case of the NA gene, A/H1N1 isolates had 97.8% to 98.5% homologies, A/H3N2 isolates had 98.9% to 99.4% homologies, and B isolates had 98.9% to 100% homologies with each vaccine strain in the 2008~2009 season, respectively. Characterization of the hemagglutinin gene revealed that amino acids at the receptor-binding site and N-linked glycosylation site were highly conserved. These results provide useful information for the control of influenza viruses in Busan and for a better understanding of vaccine strain selection.

This study is an introductory survey of the labyrinth/maze in gardens. The term 'garden labyrinth' may seem an oxymoron given that the garden represents the terrestrial paradise, while the labyrinth is a symbol of the most chaotic face of the world. In etymological and ontological terms, however, gardens are enclosed places and this characteristic corresponds to the character of the labyrinth, which is the one of the oldest signs in human civilization, symbolizing the paths of human life filled with uncertainty and complexity. The garden labyrinth has developed in various forms and shapes since the Renaissance period. Literature and paintings contributed to the dissemination of the concepts of the garden labyrinth, especially in the form of the 'garden of love'. While the labyrinths in ancient and medieval times focused on plane shapes and symbolic and/or spiritual meanings, later garden labyrinths emphasized the three dimensional form and synesthetic pleasures. New patterns, which deviated from the classical unicursal form, emerged in the Petit Parc at Versailles in the 17th century. The garden labyrinth/maze was easy to adopt in formal gardens because of its geometric form, but for that reason, it went on to decline during the fad of picturesque garden. In this study, a brief history of labyrinths, the patterns, forms, and arrangement of the garden labyrinths in the formal gardens of the Renaissance and Baroque periods and its meanings are reviewed.

The spatial distribution of meteoroids or cometary debris along the orbit of the Earth is investigated by analyzing the meteoric records in the Chronicle of the Koryo dynasty (918-1392) which is called Koryosa. Sporadic meteors in this period show the seasonal variation in number, which is similar to the current meteors. We also found that there are a few spikes showing large accumulation of records around the same dates. We regard these spikes as meteor showers in the Koryo period. We compared the dates of meteor showers with those compiled from the historical records around the world including Korea, Japan, China, Arab, and European countries. We discovered three prominent showers and four weak showers. The prominent ones are the Leonids, the Perseids, and the Aquarids and the Orionids pair. The last pair is the remnants of Halley's comet. The astronomical records written in the history book of the Koryo dynasty are turned out to be accurate and written in a steady manner. We can also see that those records can be useful to contribute the development of modern astronomy and astrophysics.

Gwaebul, created during late Joseon dynasty, especially from 1885 to 1926, now exist 18 ones. And 12 of them are owned by Buddhist temples located in Seoul city and Gyeonggido province. Royal Tomb praised and Royal household praised Buddhist temples in early Joseon dynasty were supported by Royal Family. As a renovation of Buddhist temples by king Taejong's reign(1400-1418), they became impoverished with reduced Buddhist ceremony. But they maintained their lives in intimate connection with royal family, and went prosperous from late 18th century. At that times, a new trend in Gwaebul appeared, which have popular idea for wishing peace of the dead, the nation and the royal family. The new composition of painting expressed in Gwaebul starts in Amitabha-Triad paintings which carved in first volume of ${\ll}$Amita-yohaegyeong${\gg}$ made of wooden plate. And Gi-heoh(A.D. 1820-1872) carved it in 1853 at Naewonam Buddhist hermitage of Samgaksan mountain And a return of Suwolgwaneumdo which had been popularized in late Goryo dynasty is worth noticing as a new issue of late Joseon dynasty. It is related with a composition of Gwaebul that expressed 'a leading the dead to the good', a Buddhist consciousness of falsehood and fancy. The saturated and blurred style of painting, the fact that centralization-powered lineage of painter who used composition of multi-used basic pattern, are characteristics of this period.

Purpose : To determine the prevalence and clinical features of codetected respiratory etiological agents for acute respiratory infection in hospitalized children. Methods : Nasopharyngeal aspirates were obtained from hospitalized children with acute respiratory infection at Dankook University Hospital from September 2003 through June 2005. Immunofluorescent staining and culture were used for the detection of respiratory viruses (influenza virus [IFV] types A, B; parainfluenza virus [PIV] types 1, 2, 3; respiratory syncytial virus [RSV]; adenovirus [AdV]). Polymerase chain reaction (PCR) assays were used for Mycoplasma pneumoniae (MP) and Chlamydia trachomatis (CT) detection, and PCR and culture were performed for enterovirus detection. Acid-fast staining and culture were performed for tuberculosis detection. The demographic and clinical characteristics were reviewed retrospectively from the patients medical records. Results : Evidence of two or more microbes was found in 28 children: RSV was detected in 14, PIV 3 in 10, AdV in 10, MP in 8, PIV 2 in 8, CT in 4, and PIV 1 in 3. Codetected agents were found as follows: RSV＋PIV 2, 6 patients; AdV＋MP, 4 patients; AdV＋PIV, 3 patients; RSV＋MP, 3 patients; PIV 1＋PIV 3, 3 patients. Distinct peaks of codetected agents were found in epidemics of MP and each respiratory virus. Conclusion : The codetected infectious agents were RSV, PIV, AdV, and MP, with distinct peaks found in epidemics of MP and each respiratory virus. Although advances in diagnostic methods have increased the prevalence of codetection, its clinical significance should be interpreted cautiously.
