The clinical severity of coronavirus disease 2019 (COVID-19) in children is usually mild. Most of the affected patients completely recovered from COVID-19 before being released from approximately 7-day quarantine. However, children with comorbidities are at risk of more severe disease and adverse outcomes. We report three cases of COVID-19-affected adolescents with underlying chronic respiratory difficulty due to neurologic diseases who showed sudden clinical aggravations at the time of discharge, even after full clinical improvement. Patient 1 is a 17-year-old boy with Ullrich congenital muscular dystrophy who had cardiopulmonary arrest 9 days after the initial COVID-19 symptoms. Patient 2 is a 17-year-old girl with intracerebral hemorrhage with infarction in bed-ridden status who had cardiopulmonary arrest 11 days after the initial symptoms. Patient 3 is a 12-year-old boy with intraventricular hemorrhage with hydrocephalus in bed-ridden status who showed multiorgan failure 10 days after the initial symptoms. Remdesivir, dexamethasone, and empirical antibiotics were administered with mechanical ventilation and intensive unit care. Among the three patients, two (patients 1 and 3) were alive, and one (patient 2) expired. Clinicians caring for adolescents with chronic neurologic and/or pulmonary disease should keep in mind that these patients could have sudden deterioration after recovery from the acute phase of COVID-19 around or after the time of discharge.

The purpose of this study is to suggest an improvement plan for the waterfront by conducting an empirical analysis of users of the city's waterfront. For this purpose, this study conducted a field investigation and questionnaire survey on the waterfront of Sincheon, Daegu Metropolitan City. Based on this, this study investigated the importance and satisfaction levels of environmental factors according to the purpose of using the waterfront and proposed the improvement plans through an ISA(Importance-Satisfaction Analysis). The analysis results are as follows. In the case of using the waterfront for exercise, 'The division of bicycle trails and promenades' had the highest level of importance, while satisfaction level for items with 'Convenience facilities such as vending machines, toilets and water fountains' was found to be the lowest. In the case of using the waterfront for leisure and relaxation, 'Tree shade' had the highest level of importance, and the satisfaction level of the item on 'Whether to hold events such as exhibitions' was lowest. The ISA results showed that when the waterfront was used for the purpose of exercise, leisure and relaxation, items such as 'Convenience facilities such as vending machines, toilets and water fountains', 'Cleanliness of space and water quality' and 'Water quality management' had a high level of importance, but had a low level of satisfaction, which suggests that they should be improved on a preferential basis. Next, items requiring intensive improvement for exercise purposes were 'Tree shade', 'Rest facilities such as benches and pergolas', 'Width of bicycle trails and promenades' and 'The division of bicycle trails and promenades'. Leisure and relaxation found that 'Lighting facilities' require improvement. It is expected that if a river improvement project is implemented based on the above results, effective financial commitment and investment will be made.
In order to find out the condition of flow in sewer pipes, this study investigated the characteristics of tractive force of sewage flow estimated using actual measured values of water level, velocity, and flowrate in sewers located at uppermost portion in a treatment area during dry weather periods. When the scene of sewage flow was taken by CCTV after cohesive and non-cohesive solids (tofu and sand) were put on the sewer invert, it was found that the solids could be flushed without significant interruption. In sewer with slope of 0.00319, the frequency exceeding the minimum tractive force of sewage during a weekday was zero, while it was 10 per day with slope of 0.00603. During the week of the field observation, the event to exceed the minimum tractive force occurred once, suggesting that sewer odor would potentially increase. Maximum tractive force in sewer with steep slope was 2.9-3.1 N/㎡, but with gentle slope it decreased to 1.6-1.7N/㎡. It was also observed that the interval of time maintained below the criterion of minimum tractive force increased, during weekends compared to weekdays and for the sewage including non-cohesive particles which could enter combined sewers during a storm period. This study found that the sewer sediments formed by direct feces input into sewers, through sewer pipes which were designed meeting the standard sewer design criteria, could be flushed without staying as deposited solids state for a long time.

Biological networks have been handled with the static concept. However, life phenomena in cells occur depending on the cellular state and the external environment, and only a few proteins and their interactions are selectively activated. Therefore, we should adopt the dynamic network concept that the structure of a biological network varies along the flow of time. This concept is effective to analyze the progressive transition of the disease. In this paper, we applied the proposed method to Alzheimer's disease to analyze the structural and functional characteristics of the disease network. Using gene expression data and protein-protein interaction data, we constructed the sub-networks in accordance with the progress of disease (normal, early, middle and late). Based on this, we analyzed structural properties of the network. Furthermore, we found module structures in the network to analyze the functional properties of the sub-networks using the gene ontology analysis (GO). As a result, it was shown that the functional characteristics of the dynamics network is well compatible with the stage of the disease which shows that it can be used to describe important biological events of the disease. Via the proposed approach, it is possible to observe the molecular network change involved in the disease progression which is not generally investigated, and to understand the pathogenesis and progression mechanism of the disease at a molecular level.
The dramatic rise of experience space using cultural heritage in modern architecture has been generally acknowledged in recent literature. The present study aims to investigate effective ways to enhance competitiveness in local experience space, with an emphasis on the use of cultural heritage in modern architecture. Using the case of the Sam-Rae Arts Village in Wanju-gun, Jeollabuk, this study analyzes the characteristics of the 4Es in experience economy theory. In order to arrive at findings that represent the variety of perspectives found in this context, qualitative interviews were conducted with three groups: public officials, maintenance staff in the experience center, and field experts. The results of this study revealed that the Visual Media Art Museum and Book Wooks were used for entertainment, the Corpentry Shop for education, the Book Museum for escapism, and the Design Museum Culture $Caf{\acute{e}}$ The O's for aestheticism. Additionally, depending on the commercial potential of the respective experience space, the Corpentry Shop, Book Wooks, and the Culture $Caf{\acute{e}}$ The O's were used for profit purposes while the Design Museum and the Visual Media Art Museum for non-profit. Based on the findings of the present study, effective ways to enhance competitiveness in the local experience space are suggested. First, the public nature of cultural enjoyment may be realized in a field that bears non-profit characteristics. In exhibiting works, the experience space could suggest the extra demonstration. Second, in the for-profit experience hall, the securing of tourists may help to maximize profit. In so doing, a variety of experience programs and activity spaces could be provided internally, while advertisement marketing through mobile and SNS could be reinforced externally.
This study retrospectively analyzed the test results of 235 patients who visited a medical institution in Busan from May 2022 and February 2023 and conducted both carotid ultrasonography and blood tests. The purpose of this study was to investigate the effect on intima-media thickness and blood flow velocity by measuring the intima-media thickness and blood flow velocity through carotid ultrasonography and analyzing the factors influencing the subject's body mass index and metabolic syndrome. Correlation analysis between carotid intima-media thickness and body mass showed (p=0.000) confirming that there is a correlation. As a result Correlation analysis between blood flow velocity and body mass index (p=0.015) was found, comfirming that there was a correlation. Age (p= 0.000), fasting blood glucose (p=0.002) and alcohol consumption (p=0.006) were found to be correlated with carotid intima-media thickness. An increase in Carotid intima-media thicknesses causes an increase in events caused by cardiovascular disease. Therefore, efforts must be made to exclude factors that increase Carotid intima-media thicknesses, and it will be most important to prevent cardiovascular disease through research on various prediction methods and regular checkups.
Ever since the beginning of time, caves not only have offered a place to live for humans but they have also been used as cultural spaces. That is, in the event of making some sounds in a location within the cave, the sound that is created is greatly magnified and sounds out as if it is being amplified from a giant megaphone. This, as we well know it, is known as the resonance effect. Here, the cave itself appears to function as a massive wind instrument. Especially in cases like the Altamira Cave (Spain) where cave paintings were found, the point where the cave drawings were found has commonalities in that it is a wide space and that it is usually discovered together with flutes and drums that are made with mammoth bones. We need to focus on this point. We can infer from these facts that the prehistoric people have carried out cultural activities along with their incantation rituals within those caves. In the meantime, amongst the Korean traditional arts, in the case of pansori which is a representative vocal genre, there have been examples where caves were used as practicing locations for those people who are training to perfect their singing. This is known as toguldoggong(土窟獨功) which literally means 'obtaining one's own art by oneself in the earth cave by practicing incessantly'. This process along with pokpodoggong (瀑布獨功) (same as above except that the location is by the waterfall) is the final training stage in order to become a recognized virtuoso on the part of the apprentice. This could be compared to the final annealing and finishing process of producing a metalwork. This has been a long tradition followed by most Korean traditional artists in order to perfect their sound which is harmonious with nature within natural surroundings. By honing in on this point, I have come to think about this matter repeatedly while coaching the university students in vocal singing. In short, I came to the conclusion that "the making of natural sounds will be obtained naturally within natural surroundings like caves!" Consequently, The Society for Studying Cave Sounds was inaugurated on January 1992 along with some of my students. We made use of times like vacations to go around exploring caves all over Jeju and carried out investigations of sounds along with cave exploration on an experimental basis. After 5 years, in September of 1997, we were able to host the first ever cave concert domestically at the Whale Nostril Cave(東岸鯨窟) on Wu-do. After that, we have been hosting the cave concert once every year. We have achieved a record of a total of 14 cave concerts until 2009 of this year. Out of these, 2 were held in Seokhwaeam Cave in Kangwon Province, another two were held in Manjang Cave which is a lava cave, and the remaining 10 were held in the Whale Nostril Cave of Wu-do. Along with that, I have carried out a special recording for the production of a cave music CD in May of 1999. This paper was written and organized by using the main materials that were derived from the experiences of using caves as concert halls in the past. It is hoped that this cave concert will offer a very unique experience to tourists who come to Jeju every year and give them the best possible superior natural sound effect that only Jeju caves can offer.
The purpose of this perspective research is to discuss the potential role of exercise-interventions in COVID-19, terms of prevention and prognosis in the periods of the COVID-19 vaccine. SARCO-CoV-2. COVID-19 was detected as a new virus causing severe cardiovascular and respiratory complications. It emerged as a global public health emergency and national pandemic. It caused more than 1 million deaths in the first 6 months of the pandemic and resulted in huge social and economic fluctuations internationally. Unprecedented stressful situations, such as COVID-19 blue and COVID-19 red impact on many health problems. In healthy individuals, COVID-19 infection may induced no symptoms (i.e., asymptomatic), whereas others may experience flu-like symptoms, such as ARDS, pneumonia, and death. Poor health status, such as obesity and cardiovascular and respiratory complications, are high risk factors for COVID-19 prevention, occurrence, and prognosis. Several COVID-19 vaccines are currently in human trials. However, the efficacy and safety of COVID-19 vaccines, including potential side effects, such as anaphylaxis (a life-threatening allergic reaction) and rare blood clots, still need to be investigated. On the basis of direct and indirect evidence, it seems that regular and moderate physical exercise can be recommended as a nonpharmacological, efficient, and safe way to cope with COVID-19. Physical inactivity and metabolic abnormalities are directly associated with reduced immune responses, including reduced innate, CMI, and AMI responses. Due to prolonged viral shedding, quarantine in inactive, obese and disease people should likely be longer than physical active people. Multicomponent and systemic exercise should be considered for the obese, disease, and elderly people. More mechanism research is needed in this area.
