Objectives: The number of cases of hepatitis A virus (HAV) infections has sharply increased in Korea, especially among young adults. In this study, an HAV outbreak in a facility for disabled people was investigated, and we found epidemiological differences both between 2 different generations and between generally abled and disabled groups. Methods: We analyzed the incubation period and attack rate of an HAV outbreak and investigated the prevalence of HAV antibodies among the staff and residents of a facility for the disabled. We performed a retrospective cohort study during the HAV outbreak, which lasted from February 8 to 25, 2019, including examinations of HAV antibody tests and post-exposure HAV vaccination for the staff or residents of the facility. Results: There were 9 confirmed cases in 2 staff members and 7 residents. Among 53 people (30 staff and 23 residents), except for the 9 confirmed cases and 1 staff member with a known history of HAV infection, HAV seroprevalence was seen in 16.7% of the staff under 40 years of age and 95.2% of those over 40 years of age, while the corresponding rates in the residents were 0.0% and 58.8%, respectively. Conclusions: This result implies that it is necessary to prioritize HAV vaccination for vulnerable groups and workers of residential care facilities.

Purpose: The purpose of this study was to understand the experiences of those who take care of the elderly at a long-term care facility during the COVID-19 pandemic. Methods: Colaizzi's phenomenological research method was applied to describe the meaning and nature of the experiences of eight workers in an elderly care facility during the COVID-19 crisis. Results: Studies have shown that these workers experienced 'fear from infectious disease' and had the opportunity to 'reflect upon life changed by infectious disease.' They also worked together to overcome the crisis by 'protect nursing home with the nurses at COVID-19 sites' and felt 'safety from the nursing home,' and experienced 'a strong sense of calling for the job' through the crisis. Conclusion: This study is the first of its kind conducted in Korea on workers in an elderly care facility. The results indicate that it is necessary to supports these workers with practical useful education, counseling, and emotional support during the epidemic.

Objectives : This study aims to analyze differences in the use of postpartum care services and identify the factors affecting their use. Methods : Data were collected from the 2008-2014 Korean Health Panel. Chi-square tests were conducted to analyze differences in the characteristics of women after birth by the use of postpartum care services. Logistic regression analysis was used to identify factors affecting the use of each type of postpartum care service. Results : Participants with higher education and household income levels were more likely to use a postpartum care facility. Individuals with a lower number of household members, who gave birth in 2011-2013, and who used hospitals specializing in obstetrics and gynecology had a greater likelihood of using a postpartum care facility. The probability of using a postpartum caretaker was higher when participants did not perform any economic activities. Conclusions : It is meaningful to confirm that use patterns and determinants of postpartum care facilities and postpartum caretakers are completely different and that the socioeconomic status of women affects the utilization of postpartum care facilities.

Objectives: Carbon dioxide ($CO_2$) may be one of the biggest causes of climate change. The purposes of this study were to reduce greenhouse gases and to increase strawberry production by developing the supply devices in livestock facilities using the membrane technology Methods: Carbon dioxide was collected from beside to livestock facilities. The injection of $CO_2$ was stopped when it reached 1,000 ppm in the facility house. Case group with injection of $CO_2$ was compared to control group with normal environment. The experiments were conducted for 8 days from December 11, 2017. Results: Total strawberry production was found to be 1,317 kg in the case group and 1,176 kg in the control group. The correlation between $CO_2$ and crop yields has led to some statistical evidence that carbon dioxide helps to grow (${\beta}=0.832$, p<0.05). Conclusions: This study identified the potential for efforts to reduce the $CO_2$ in farming households. Increased concentrations of $CO_2$ have shown that strawberries have a better growth condition. In addition, it can be explained that the plants need wide leaves to quickly absorb much $CO_2$.

It has been studied that the measurement of odor component emission at confectionery manufacture. The objects of this study were to investigate reduction of offensive odor. The survey effects of odorous materials are presented as follows. The countermeasure of operating process is to minimize sludge sediment in each unit facility. Especially, in summer, we have to clean the sludge frequently, because anaerobic decomposing is likely to occur easily. The sludge or scum from sedimentation tank pond, and floating tank should be treated quickly. We should avoid overloading operation. In the case of overloading, dissolved oxygen should be increased, the quality of wastewater input should be decreased. When dried cakes from condense tank or floating tank are left in treatment plant, we should cover, to prevent diffusion of smell with masking materials. The seasonal condition of operating should be fixed and the kind of coagulants should be changed because the wastewater in each season have different loading rates and organic materials. Odorous materials are very sensitive to the seasonal temperature variation. Especially, when the amount of rainfall is small and the high temperature of maintenance in long periods, air diffusion rate is large, so odorous materials can make great effect on surroundings comparision with other periods. To reduce odorous gas, as short term method, we had better take ceramic addition method. Especially, in summer we should take ceramic addition method. Also, as long term method, the size of wastewater treatment facility is the most important in the normal operating of wastewater treatment facility. But wastewater treatment facilities in this factory are too old, treatment process is old fashion, and the size is too small. So, large wastewater quantity to treat in summer. As results, the expansion of wastewater treatment facility and the process of improvement are required. Restriction level of odor was exceed. As it is overloaded in summer, the basis cause of odor is that the size of wastewater treatment facility is small. The prediction of air quality equilibrium density variation show that the odorous materials from working place are Amine materials whose smell strength is about 2.5(a little strong degree). We can suppose that in summer is sensitive to temperature variation, smell strength is larger as to reduce the origin of odor. We must expand wastewater treatment facility and improve the process A.S.A.P.

The purpose of this study is to analyze the emergency health care utilization using status according to income class. The target was the 2011 data out Korea Health Panel's raw data. 2011 data composed of total 17,035 people from total 5,741 households. This study set total 1,101 adults over full-20-years old having used an emergency health care utilization as its analysis target. In order to find out the number of emergency health care utilization use according to income class and the influential factors on emergency health care utilization cost, this study conducted the multiple regression analysis. And in order to more accurately analyze the emergency health care utilization use status depending on the income class and the features of emergency health care utilization use status, this study developed Models. As the result, this study found following findings. First, as the income class was lower, the gender was male, the age was lower, and the user has spouse, the user was not a business owner or a paid worker, the user is a house owner, the emergency medical facility type was a clinic, the means of transportation was others rather than 119 ambulance, the reason visiting emergency medical facility was belonged to others rather than accidents or poisoning, then the number of emergency was increased. Second, as the user was in higher income class, received the health insurance benefits, the using medical facility was general hospital, used 119 ambulance more often, stay days in emergency was shorter, then health care utilization cost was increased. In this study investigating the data out of Korea Health Panel, it was found that while the number of emergency health care utilization use was increased in the lower income class, but the emergency health care utilization cost was increased for higher income class. It is considered that this finding was caused from the facts that lower income class was more often exposed to dangers for physical health, so the number of emergency health care utilization use was increased, but their health care utilization cost was decreased because of their economic burdens against various examinations and their difficulties to pay such costs, comparing to that of higher income class. Therefore, in order to solve unequal problem of emergency health care utilization use between lower and higher income classs, it is required to set suitable solutions like the disease prevention effort by facilitating national health check-up programs, the enhancement of public health services in quantity and quality, the emergency health care utilization securing policy at using medical facilities, the promotional, educational activities about emergency health care utilization delivery system, the enhanced accessibility of emergency health care utilizations and emergency medical facilities.
