This study considered organic matter decomposition by ocenic microbes as researching organic matter decomposition on kinetics which is in salinity wastewater under condition that the salinity contains 18,000㎎/l Cℓ^(-) The results of this study are obtained as following : 1. Oceanic microbe of this study is yeast, R. glutinis var. salinaria of marina of Rhodotorula genuses. 2. When retention time of filter bed in Bio-coal tower is 24 hr, 1/2V_(max) is 33.75㎎/l·hr, When 72hr, 1/2V_(max) is 15㎎/l·hr, When 120hr, 1/2V_(max) is 10㎎/l·hr. 3. The reaction between oceanic microbes and organic matter is said to be first order and when contact time of filter bed is 2.0hr, k is 0.40 day^(-1).

This article identifies the two key functions that doctors should perform prior to accepting terminally ill patients` requests for hospice care. In the first place, doctors caring for terminally ill patients should inform relevant family members of the patient`s condition, provide patients and family members with information on hospice care, and offer patients an opportunity to choose to receive hospice care or not. Secondly, doctors should consult with other medical professionals concerning patients` choices and, when appropriate, provide hospice care needs for terminal patients and their families. In order to perform these two functions effectively, doctors caring for terminally ill patients should be provided with due information on hospice care. This article reviews the relevant moral justifications for providing hospice care and argues that it not only satisfies both medical and ethical objectives but is also in terminal patients` best interests.

Background: As the coronavirus disease 2019 (COVID-19) pandemic is ongoing, heavy workload of healthcare workers (HCWs) is a concern. This study investigated the workload of HCWs responding to the COVID-19 outbreak in South Korea. Methods: A nationwide cross-sectional survey was conducted from September 16 to October 15, 2020, involving 16 healthcare facilities (4 public medical centers, 12 tertiary-care hospitals) that provide treatment for COVID-19 patients. Results: Public medical centers provided the majority (69.4%) of total hospital beds for COVID-19 patients (n = 611), on the other hand, tertiary care hospitals provided the majority (78.9%) of critical care beds (n = 57). The number of beds per doctor (median [IQR]) in public medical centers was higher than in tertiary care hospitals (20.2 [13.0, 29.4] versus 3.0 [1.3, 6.6], P = 0.006). Infectious Diseases physicians are mostly (80%) involved among attending physicians. The number of nurses per patient (median [interquartile range, IQR]) in tertiarycare hospitals was higher than in public medical centers (4.6 [3.4–5] vs. 1.1 [0.8–2.1], P = 0.089). The median number of nurses per patient for COVID-19 patients was higher than the highest national standard in South Korea (3.8 vs. 2 for critical care). All participating healthcare facilities were also operating screening centers, for which a median of 2 doctors, 5 nurses, and 2 administrating staff were necessary. Conclusion: As the severity of COVID-19 patients increases, the number of HCWs required increases. Because the workload of HCWs responding to the COVID-19 outbreak is much greater than other situations, a workforce management plan regarding this perspective is required to prevent burnout of HCWs.
