The oxidation ditch (OD) is one of the most widely used processes for treating municipal wastewater. However, the microbial communities in the OD systems have not been well characterized, and little information about the shift of bacterial community during the startup process of the OD systems is available. In this study, we investigated the bacterial community changes during the startup period (over 100 days) of a full-scale OD. The results showed that the bacterial community dramatically changed during the startup period. Similar to the activated sludge samples in other studies, Proteobacteria (accounting for 26.3%-48.4%) was the most dominant bacterial phylum in the OD system, but its relative abundance declined nearly 40% during the startup process. It was also found that Planctomycetes proliferated greatly (from 4.79% to 13.5%) and finally replaced Bacteroidetes as the second abundant phylum in the OD system. Specifically, some bacteria affiliated with genus Flavobacterium exhibited remarkable decreasing trends, whereas bacterial species belonging to the OD1 candidate division and Saprospiraceae family were found to increase during the startup process. Despite of the bacterial community shift, the organic matter, nitrogen, and phosphorus in the effluent were always in low concentrations, suggesting the functional redundancy of the bacterial community. Moreover, by comparing with the bacterial community in other municipal wastewater treatment bioreactors, some potentially novel bacterial species were found to be present in the OD system. Collectively, this study improved our understandings of the bacterial community structure and microbial ecology during the startup of a full-scale wastewater treatment bioreactor.

Backgrounds : Since December 1, 2009, National Health Insurance began to reimburse for three physical therapies of Korean medicine. The extension of insurance coverage is demanded by Korean medicine societies. Objectives : This study aimed to measure the resource-based relative value scale (RBRVS) scores for thirty four physical therapies of Korean medicine and to estimate the insurer's expenditure for them in National Health Insurance. Methods : To measure the physician's work and the practice expense, the 'magnitude estimation method (MEM)' and the 'fully distributed cost - attributable cost method (FDC-ACM)' were applied respectively. We collected the frequency data of physical therapies from Korean medicine hospitals and clinics to estimate the total expenditure. Results : The resource-based relative value scale scores of physical therapies were measured from 23.44 to 160.66. Total insurer's expenditure was calculated to be 95.5 billion won as of 2009. Conclusions : Based on the result that showed minor increase of total expenditure, most physical therapies of Korean medicine need to be reimbursed in the National Health Insurance.

Objectives: This study examined the extent to which attitudes about smoke-free air policies (SFAPs) in bars/restaurants, workplaces, all public places, and motor vehicles when minors are present can be explained by individuals' sociodemographic characteristics, smoking status, and beliefs about the health of others. Methods: Data were gathered from 359 individuals age 18 or older who attended the Lawrence County Fair in Indiana, United States, in July, 2009, an area where there were no SFAPs in place at the time of survey administration. Results: Multinomial logistic regression analyses indicated that perceived severity of secondhand smoke (SHS) on others, perceived responsibility of smokers for the harm their SHS causes to others, and perceived susceptibility of others to SHS exposure, along with education level and smoking status, significantly predict opposition to SFAPs in this population. Conclusions: The results of this exploratory study suggest the need for additional research related to attitudes about health policies as well as to the practical applications of these findings for smoke-free air advocacy.

This study examines health and life satisfaction of the married female production workers(Mfpw). The data of 370 Mfpw in manufacturing sector in Taegu are collected by using questionares in August, 1995. Health scale measured by Todai Health Index is composed physical health and mental health. There are three satifsfaction areas-individual life satisfaction, family life satisfaction, and job satisfaction-in the overall life satisfaction scale. The findings of this study are as follows: 1) Mfpw’s total health conditions are poor. Especially physical health is worse than mental health. Physical health is influenced by age and purpose of attaining job, while mental health is influenced by purpose of attaining job. Mfpw who get the job for family financial needs have poor physical and mental health. 2) The overall life satisfaction level of Mfpw is lower than middle point : their family life satisfaction level is the heigest and their individual life satisfaction level is the lowest. Family income, purpose of attaining job and work place environment have effect on the level of overall life satisfaction. Mfpw who have the higher family income, get the job by non-economic motivations and work in good work place environment show the higher life satisfaction level.

의료 정보의 상호운용성 향상을 위해서 Health level 7은 의료 정보 교환을 위한 차세대 체계인 Fast health interoperability resource (FHIR)를 개발하였다. 그러나, 이를 이용하여 임상 정보를 포함한 3차원 의료 영상을 교환하려는 시도는 없어 새로운 방법을 제시하고자 한다. CT 영상에서 만들어진 3차원 의료 영상을 javascript object notation (JSON) 형식으로 전환하고, 임상 정보를 추가하였다. 우리는 시험용 FHIR 서버를 만들고, 클라이언트는 postman을 사용하였다. 생성된 JSON 파일은 body에 첨부하여 전송되었다. JSON 형식으로 전송된 3차원 의료 영상은 웹 브라우저를 통해서 볼 수 있었고, 원시 코드를 확인하여 동봉된 임상 정보를 볼 수 있었다. 우리는 3차원 의료 영상 교환을 최초로 시행하였다. 이 방법을 적용한 앱이나 FHIR 리소스 개발을 위해 추가적인 연구가 필요할 것이다.

The purpose of this study is to examine the influence of parent-to-child financial transfers and economic resources on financial transfers, caregiving, and time donated from middle-aged adult children to their elderly parents. Analyzing data from the Wisconsin Longitudinal Study, which provides long-term observations of financial reciprocity and recent reports about elder care, the current study finds strong positive effects of prior parent-to-child financial transfers in the models of caregiving and time; which indicates the importance of reciprocity. In terms of determinants of resource transfers, the findings of logistic regression analyses suggest that the economic resources of parents and adult children are strong determinants of child-to-parent financial resource transfers. Sociodemographic characteristics of parents and respondents were observed as strong determinants of caregiving or time. In addition, caregiving responds more to the health and income levels of parents whereas donated time is responsive to the net worth of parents and parents' status. For adult children, gender is a strong determinant of both caregiving and time donation. The long-term health problem of adult children is a statistically significant predictor of caregiving, while the employment status of adult children and the number of siblings have statistically a significant association with time donated to care for the parents.

Purpose: This paper analyzed alternative methods of calculating the conversion factor for nurse-midwife's delivery services in the national health insurance and estimated the optimal reimbursement level for the services. Methods: A cost accounting model and Sustainable Growth Rate (SGR) model were developed to estimate the conversion factor of Resource-Based Relative Value Scale (RBRVS) for nurse-midwife's services, depending on the scope of revenue considered in financial analysis. The data and sources from the government and the financial statements from nurse-midwife clinics were used in analysis. Results: The cost accounting model and SGR model showed a 17.6-37.9% increase and 19.0-23.6% increase, respectively, in nurse-midwife fee for delivery services in the national health insurance. The SGR model measured an overall trend of medical expenditures rather than an individual financial status of nurse-midwife clinics, and the cost analysis properly estimated the level of reimbursement for nurse-midwife's services. Conclusion: Normal vaginal delivery in nurse-midwife clinics is considered cost-effective in terms of insurance financing. Upon a declining share of health expenditures on midwife clinics, designing a reimbursement strategy for midwife's services could be an opportunity as well as a challenge when it comes to efficient resource allocation.

Disinfection is a very important process in water plant on account of our surface water usage. Particularly. the rainfall of Korea is concentrated in summer time. it is almost carried away to ocean before our utilization as water resource. To overcome the unbalance of water resource, artificial dams and reservoirs are constructed. According to such storage of water to aggravate water pollution and make the increase of water cleaning chemicals. Chlorine, as a main traditional chemical for water treatment. is focused on account of THMS formation in recent days. In this paper. the data of a water plant located in Seoul is adopted as the foundation of water quality analysis and introduce the substitute chemicals to supplement the harmful formation. additionally. Conclusions are summarized as follows: 1. The water quality of water resource is the worst in summer time and the supply of cleaning chemical is inevitably increased on account of general bacteria increase. 2. Chlorine, as a main chemical for water cleaning, formed the cancer-causing organic THMS with water molecules. 3. One of substitute chemical. chlorine dioxids suppress the formation of THMS comparing with the case of chlorine only. Therefore. the continuous research of substitute chemicals should be activated. 4. As the supply of disinfected clean water concerned with the citizen sanitary, the cultivation of professionals and academic conference must be needed on the basis of nation

Background: This study seeks to examine the relationship and impact of occupational health and safety on employees' organizational commitment in Ghana's mining industry. The study explores occupational health and safety and the different dimensions of organizational commitment. Methods: A cross-sectional survey design was used for this study. The respondents were selected based on simple random sampling. Out of 400 questionnaires administered, 370 were returned (77.3% male and 22.7% female) and used for the study. Correlation and multiple regression analysis were used to determine the relationship and impact between the variables. Results: The findings of this study revealed positive and significant relationship between occupational health and safety management, and affective, normative, and continuance commitment. Additionally, the results revealed the significant impact of occupational health and safety on affective, normative, and continuance commitment. Conclusion: Management within the mining sector of Ghana must recognize the fact that workers who feel healthy and safe in the performance of their duties, develop emotional attachment and have a sense of obligation to their organization and are most likely committed to the organization. Employees do not just become committed to the organization; rather, they expect management to first think about their health and safety needs by instituting good and sound policy measures. Thus, management should invest in the protection of employees' health and safety in organizations.
