The standard design methodology was suggested to construct wetland system for reducing non-point source pollution from Saemangeum reclaimed paddy land. To set for the design flow and concentrations, runoff and water quality survey were conducted during the irrigation period in 2008 at Gyehwa reclaimed paddy land located at near Saemangeum lake. It is rational that 1ha is the optimum constructed wetland size. To meet this size, the moderate drainage area of reclaimed paddy field was 50ha under the conditions that rainfall is 30mm, average runoff coefficient is 0.83, and runoff capture ratio is 0.6. At these condition, the runoff volume from 50ha was 10,520 $m^3/d$ including base flow during irrigation period. To select the optimum wetland system, several case studies were conducted by focusing on the tidal reclaimed land areas having wetland systems in Seokmun. Pond-Wetland system was selected as the standard model because of showing the highest reduction efficiency. Single variable regression equation were delivered to estimate effluent water concentrations from the designed wetland by using long-term monitoring data from the Seokmun experiment site. The effluent concentration from the designed wetland using these equation were showed moderately range.

Purpose: This study aimed to examine the factors associated with postpartum depression and its influence on maternal identity of postpartum women. Methods: Research design was a cross sectional descriptive study with a total of 89 women within the six month postpartum period. Associations of eating habits, overall sleep quality and other factors with postpartum depression utilizing the Korean Beck Depression Inventory (K-BDI) were done. The influence of postpartum depression on maternal identity was analyzed. Variables yielding significant associations (p<.05) were included in an adjusted logistic regression and a stepwise multiple regression. Results: Mean scores of postpartum depression was $9.42{\pm}6.08$ and 31.5% (n=28) for mild depression, 11.2% (n=10) was moderate and 4.5% (n=4) was severe depression on the K-BDI scale. Perceived health status and overall sleep quality were predictors of postpartum depression. Postpartum depression and the husband's love were predictors of maternal identity. Conclusion: Awareness of poor health perception and sleep quality will be helpful to detect for postpartum depression. Strategies to increase maternal identity during the postpartum period would be tailored by level of depression.

Purpose: This study investigated sleep satisfaction and influencing factors in Korean adolescents with atopic dermatitis. Methods: Data were obtained from 4,570 subjects who completed the 2017 13th Korea Youth Risk Behavior Web-based Survey. For data analysis, descriptive statistics and multiple-sample logistic regression were used. Results: The results of this study were as follows. Gender, academic achievement, economic status, perceived stress, happiness, health status, and depression in the subjects showed a significant difference in terms of sleep satisfaction in atopic adolescents. Multiple-sample logistic regression analysis showed that male adolescents (odds ratio (OR)=0.48), academic achievement (low OR=0.67, middle OR=0.78), economic status (low OR=0.50, middle OR=0.64), lack of depression (OR=0.63), perceived stress (very OR=4.65, a little OR=2.25), perceived happiness (unhappy OR=1.99, moderate OR=1.22), perceived health status (unhealthy OR=2.17, ordinary OR=1.35), alcohol nondrinking (OR=0.75), and nonsmoking (OR=0.73) were not associated with sleep satisfaction. Conclusion: It is necessary to develop interventions that can relieve stress management and depression and develop positive emotions in atopic adolescents. In addition, there is a need to improve the environment to avoid health risks such as alcohol consumption and smoking and to minimize the effects of passive smoking.

Purpose: The present study examined the psycho-emotional factors that affect the retention intention among advanced beginner-stage nurses. Methods: A cross-sectional study was conducted using a convenience sample of 118 nurses with a work experience of at least one to three years of work experience in a university hospital in Suwon, Korea. Structured questionnaires were used to assess retention intention, emotional labor, and resilience. Multiple regression analysis was used to examine factors affecting retention intention. Results: Retention intention had a moderate mean score (4.75 out of 8). Factors influencing participants' retention intention were founded in the order of resilience (β=.29, p<.001) and emotional labor (β=-.20, p=.011) after adjusting nursing satisfaction as a covariate. The multiple regression model accounted for 42% of the variance in retention intention (p<.001). Conclusion: Resilience and emotional labor may be primary factors influencing retention intention of advanced beginner-stage nurses. Therefore, this study finding suggested that psycho-emotional factors such as emotional labor and resilience should be considered while designing programs to increase nurses' retention intention.

Purpose: We examined the relationship between the health-related issues of elderly women and bone density and identified specific factors that affect the prevalence of osteoporosis to provide basic data for developing a health care program on osteoporosis prevention. Methods: This study is a secondary data analysis of 118,903 66-yr-old women who received a health examination conducted by the National Health Insurance Corporation in 2008. Multiple logistic regression analysis was used to identify factors affecting the prevalence of osteoporosis. Results: The prevalence of osteoporosis was 46.8%, whereas the prevalence of osteopenia was 38.4% among elderly women in this study. Statistically significant differences were observed between the osteoporosis and non-osteoporosis group in terms of smoking (p<.001), exercise (p<.001), obesity (p<.001), waist circumference (p<.001), depression (p<.001), falling experience (p<.05), and the cognitive function risk (p<.05). Based on the multiple logistic regression results, the risk for osteoporosis was high in those who were under-weight, smoked, or were depressed. In contrast, moderate or high level obesity showed a negative relationship with osteoporosis. Conclusion: The prevalence of osteopenia and osteoporosis was 85.2%. Therefore, there is a need to develop health care programs pertaining to osteoporosis intervention and prevention for elderly women. Because smoking, non-exercise, and obesity are main osteoporosis risk factors, it is highly recommended that some sound practical life programs and psychological support programs be considered for this population.

Objective: Despite known associations between negative body image and health declines in chronic pain patients, few studies have examined longitudinal associations between psychological stress and perceived hand deformities. This study examined whether psychological distress was associated with hand deformities 4 years later and if rural and urban adults differed in the association. Design: A community-based cohort study. Methods: Community dwelling adults (mean age=51.97, 52.3% women) in a rural (n=2968) and urban area (n=2784) provided demographic data at baseline and, in the 4-year follow-up, responded to questionnaires about psychological distress. Perceived hand deformities were assessed at the 8-year follow-up. Linear regression was conducted to examine the effects of psychological distress on hand deformities and moderation by residential areas. Results: The perceived hand deformities were more likely among those with severe psychological stress, hand osteoarthritis, or any chronic disease condition (p<0.01) but less likely among those with younger age, higher education, or income (p<0.01). The regression results showed that psychological distress predicted more perceived hand deformities 4 years later even after adjusting for demographic and health covariates (p<0.01). The residential areas did not significantly moderate the association between distress and hand deformities. Conclusions: This study suggected that psychological distress may trigger later perception of hand deformities in both urband and rural adults. The findings indicate that stress management interventions that are customizable to regional contexts may be effective at preventing negative body image related health problems of community-dewelling adults.

Recent two moderate earthquakes (2016 $M_w=5.4$ Gyeongju and 2017 $M_w=5.5$ Pohang) in Korea provided the unique chance of developing a set of relations to estimate instrumental seismic intensity in Korea by augmenting the time-history data from MMI seismic intensity regions above V to the insufficient data previously accumulated from the MMI regions limited up to IV. The MMI intensity regions of V and VI was identified by delineating the epicentral distance from the reference intensity statistics in distance derived by using the integrated MMI data obtained by combining the intensity survey results of KMA (Korea Meteorological Administration) and 'DYFI (Did You Feel It)' MMIs of USGS. The time-histories of the seismic stations from the MMI intensity regions above V were then preprocessed by applying the previously developed site-correction filters to be converted to a site-equivalent condition in a manner consistent with the previous study. The average values of the ground-motion parameters for the three ground motion parameters of PGA, PGV and BSPGA (Bracketed Summation of PGA per second for 30 seconds) were calculated for the MMI=V and VI and used to generate the dataset of the average values of the ground-motion parameters for the individual MMIs from I to VI. Based on this dataset, the linear regression analysis resulted in the following relations with proposed valid ranges of MMI. $MMI=2.36{\times}log_{10}(PGA(gal))+1.44$ ($I{\leq}MMI$$MMI=2.44{\times}log_{10}(PGV(kine))+4.86$ ($I{\leq}MMI$$MMI=2.59{\times}log_{10}(BSPGA(gal{\cdot}sec))-1.02$ ($I{\leq}MMI$

Objective : This study was performed in order to provide basic data for halitosis prevention and establish a device to efficiently eliminate halitosis and to analyze the factors that affect the halitosis. Methods : Oral examination on the Gingival index, CPITN, Tongue Plaque index, and OHI-S as well as halitosis measurement among 293 rural residents. Results : Gingival index was high at mild on female and at moderate on male(p=0.025). Sorting the result by age, mild was 54.1% in the 40s, and moderate was 49.5%, 42.0% and 70.0% each in the 50s, 60s, and the 70s(p=0.005). The need for dental plaque management was 100%. The need for scaling was high with 78.3%, 93.0%, 89.9%, and 90.0% each for the 40s, 50s, 60s, and 70s. The need for complex periodontal treatment was also high with 32.4%, 47.5%, 48.7% and 60.0%, each for the 40s, 50s, 60s, and 70s(p=0.050). The highest bad condition for OHI-S was 69.5%, and good being 18.9%, and very bad being 11.6%. For moderate tongue plaque index was 74.4% as the highest. As the level of education increased, the slight tongue plague was increased, but in contrast, the moderate and higher tongue plague index was decreased(p=0.010). OG under 50ppm was 61.1% on male and OG over 50ppm was 50.9% on female(p=0.041). In OG over 50ppm, CPITN was 52.1% and 41.9% in scaling and complex periodontal treatment group(p=0.018). OHI-S, in bad and very bad condition with OG, over 50ppm, was 48.7% and 46.9%(p=0.019). The higher tongue plague index showed significant amount of increase at OG and EG above 50ppm(p=0.006). $NH_3$, as the tongue plaque index increased, the wider range of distribution was shown(p=0.000). As for the multiple regression analysis result, there have been selected females and tongue plaque index as factors affecting OG. There have been selected age and tongue plaque index as factors affecting EG and there have been selected females as factors affecting on $NH_3$. Conclusions : With the aforementioned results in mind, the status of halitosis among rural residents is considered to bare a close relation with oral environments. we have to focus on correct tooth brushing methods and tongue brushing, with using tongue cleaner to remove fur of tongue plaque. Also, in order to analyze exactly the factors of individual halitosis, we need continuous and systematic study.
