This research is devoted to increase resuscitation rate of emergency patients, expanding CPR to a pan-national campaigning, revaluating popularity and suitability of the education about the existing CPR(Bystander cardiopulmonary resuscitation) education expansion of 119 EMS. Questionnaire was carried from seven hundred fifty eight residental and students in kyuggi fist area(Southern suwon, Middle suwon, Osan, Young-in) from July 20 to July 30, 2006. The institutional support for CPR education and special eduction institution are not prepared, 52.44% of those have CPR education, according to questionnaire. 39.9% of the educated is from 119 EMS and it is big outcome, 119 EMS efforts in the vortex of poor surroundings. But, 69.76% of the uneducated said they had not chance of CPR education and 19.63% said that the reason is no special eduction institution and information for CPR education. They say that CPR education was carried for only applicants in 119 EMS, without systematic and institutional support, special eduction institution. So, we have to expand the infrastructure, institute CPR education for systematic propagation of CPR education. And we need to make plan constructive public relations, intensify maintaining of CPR educated.

Soil-gas radon level and other atmospheric factors have been measured at residual soil profiles that overlie granite bedrock which consists of major geology in Korea for 6 months from November, 2000 to April, 2001. Seasonal variations of soil-gas radon concentration are generally of greater magnitude than day-to-day fluctuations. The highest radon concentrations of 5,131 pCi/L measured during winter season and the lowest radon concentrations of 107 pCi/L during spring season. Two study areas, Bongcheon-dong(granite bedrock) and Seongnam-Yongin(gneiss bedrock) were investigated to assess the radon potential according to their field survey and emanation tests. The mean values of radon decrease in sequentially from Suji-A(813 pCi/L)>Suji-B(757 pCi/L)>Bundang-B(691 pCi/L)>Bundang-A(643 pCi/L)>Bongcheon-dong(513 pCi/L). Estimated soil-gas radon potential using maximum radon emanation ratios of each study area decreases in the order of Bongcheondong(950 pCi/L)>Suji-B(524 pCi/L)>Bundang-A(437 pCi/)>Bundang-B(259 pCi/L)>Suji-A(230 pCi/L) areas. The values of indoor radon and its daughter product concentrations in Bongcheon-dong area show that indoor basement rooms in poor ventilation condition could be classified as extremely high radon risk location of more than 4 pCi/L Rn and 0.02 WL.

Background: The appropriate use of drugs is very important for a healthy life, as appropriate medication must be taken correctly for successful treatment of a disease. The purpose of this study was to investigate the self-efficacy between health status and drug abuse behavior. Methods: The subjects of this study were selected from 15 workshops located in Seoul, Incheon, Daejeon, and Chungnam, and, convenience sampling was conducted for each employee between September, 2017 and October 2017. A total of 204 questionnaires were analyzed. The questions evaluated health status, self-efficacy, drug abuse behavior, and general characteristics. Results: First, there was no difference in health status according to the general characteristics of the subjects. The self-efficacy varied according to gender, educational background, and monthly income, but not by marital status and residence area. In addition, drug abuse behaviors differed according to gender, residence area, and monthly income, but not by marital status and education level. Second, drug abuse behavior negatively correlated with health status and self-efficacy. Third, regression analysis showed that the self-efficacy between the health status and drug abuse behavior had a partially mediating effect. Conclusion: In patients with poor health status, it is necessary to increase their self-efficacy to reduce reduce drug abuse. Therefore, regular education programs targeting efficacy and drug knowledge are required in the community.

A number of experiments to treat wastewater of a dye plant were conducted to investigate the basic design parameters and effluent characteristics for aerobic fixed biofilm reactor upon the variation of organic loading rate. The media used for this study were SARAN 4000 D with specific surface area $153m^2/m^3$, and 1000 D with specific surface area $307m^2/m^3$. The influent COD concentration ranged from 1250 to 4080 mg/L. Substrate removal and variation of biomass concentration were observed. At the beginning, the effluent quality was poor but improved as the time passed. However the effluent quality became seriously deteriorated when the media clogged. At influent COD of 1250mg/L, the effluent COD varied little, even if the organic loading rate increased from 0.63 to 2.5kg COD/$m^3$/day. It was also noted that the design parameters for activated sludge process could be applied to an aerobic fixed biofilm process under the experimental conditions.

Background: This study used receiver operating characteristic curve to analyze Surveillance, Epidemiology and End Results (SEER) adenosquamous carcinoma data to identify predictive models and potential disparities in outcome. Materials and Methods: This study analyzed socio-economic, staging and treatment factors available in the SEER database for adenosquamous carcinoma. For the risk modeling, each factor was fitted by a generalized linear model to predict the cause specific survival. An area under the receiver operating characteristic curve (ROC) was computed. Similar strata were combined to construct the most parsimonious models. Results: A total of 20,712 patients diagnosed from 1973 to 2009 were included in this study. The mean follow up time (S.D.) was 54.2 (78.4) months. Some 2/3 of the patients were female. The mean (S.D.) age was 63 (13.8) years. SEER stage was the most predictive factor of outcome (ROC area of 0.71). 13.9% of the patients were un-staged and had risk of cause specific death of 61.3% that was higher than the 45.3% risk for the regional disease and lower than the 70.3% for metastatic disease. Sex, site, radiotherapy, and surgery had ROC areas of about 0.55-0.65. Rural residence and race contributed to socioeconomic disparity for treatment outcome. Radiotherapy was underused even with localized and regional stages when the intent was curative. This under use was most pronounced in older patients. Conclusions: Anatomic stage was predictive and useful in treatment selection. Under-staging may have contributed to poor outcome.

Background: This study used receiver operating characteristic (ROC) curves to screen Surveillance, Epidemiology and End Results (SEER) skin melanoma data to identify and quantify the effects of socioeconomic factors on cause specific survival. Methods: 'SEER cause-specific death classification' used as the outcome variable. The area under the ROC curve was to select best pretreatment predictors for further multivariate analysis with socioeconomic factors. Race and other socioeconomic factors including rural-urban residence, county level % college graduate and county level family income were used as predictors. Univariate and multivariate analyses were performed to identify and quantify the independent socioeconomic predictors. Results: This study included 49,999 parients. The mean follow up time (SD) was 59.4 (17.1) months. SEER staging (ROC area of 0.08) was the most predictive foctor. Race, lower county family income, rural residence, and lower county education attainment were significant univariates, but rural residence was not significant under multivariate analysis. Living in poor neighborhoods was associated with a 2-4% disadvantage in actuarial cause specific survival. Conclusions: Racial and socioeconomic factors have a significant impact on the survival of melanoma patients. This generates the hypothesis that ensuring access to cancer care may eliminate these outcome disparities.

The purpose of this study was to evaluate and to analyze the spatial composition by block plan of the free elderly facility and to provide basic information for building up the detail architectural guidelines. The results of the study were as follows: Elderly welfare law needed to control the poor physical environments of the free elderly facility such as the residential space for more than 4 individuals. The facility of single building type should strengthen the informal support networks through the dispersion of public spaces or should encourage moving of the residents through the outdoor space, especially in rural area. On the other hand, the linking type needed to focus on the administrative spaces on the first floor for the managerial convenience, and to group and disperse the public/recreational spaces to decrease the unnecessary moving of the residents and staffs. The passageway linking building to building should directly connect each administrative space or public space so that elderly used them without any inconvenience. In the dispersion type, which is suited to rural area, the lounge, dining hall, and the place for the staff on duty should be located in the same as the residence building for the convenience and the safety of the elderly residents.

The main purpose of this project is to improve the funeral and grave culture which has brought about many social problems, and to fix the crematory culture as the future funeral ceremony in our country. In this study, we first investigated the actual condition of cremation culture. Second, we survey three representative crematorium as an object of study and investigated similar sample buildings in Japan, we analyzed the problem of existing crematorium. Finally, we arranged the basics to approach the space program and design criteria of this project. 1. The entrance of vehicles has been commonly concentrated to the opening time of crematorium. therefore, Peak time has come out as circulation of cremation and waiting time is increasing, also it is difficult to manage the congestion normally. 2. The whole problem of crematorium is poor environment, inferior buildings, noise, unsatisfactory ventilation and privacy, insufficient convenience facilities. 3. The user demand on the crematorium facilities is a private family room for waiting area, a farewell room for family members in a direct line, an outdoor rest area, and the various service facilities, and so on. 4. For improvement of the funeral and grave culture, it is necessary that crematorium is not a hatred facilities, as the conversion of consciousness, and to new shape of charnel as it wore family tomb.

A prototype GIS-based decision support system (DSS) was developed by using a database management system (DBMS), a model management system (MMS), a knowledge-based system (KBS), a graphical user interface (GUI), and a geographical information system (GIS). The method of selecting a dispersion model or a modeling scheme, originally devised by Park and Seok, was developed using our GIS-based DSS. The performances of candidate models or modeling schemes were evaluated by using a single index(statistical score) derived by applying fuzzy inference to statistical measures between the measured and predicted concentrations. The fumigation dispersion model performed better than the models such as industrial source complex short term model(ISCST) and atmospheric dispersion model system(ADMS) for the prediction of the ground level $SO_2$ (1 hr) concentration in a coastal area. However, its coincidence level between actual and calculated values was poor. The neural network models were found to improve the accuracy of predicted ground level $SO_2$ concentration significantly, compared to the fumigation models. The GIS-based DSS may serve as a useful tool for selecting the best prediction model, even for complex terrains.

Objectives : The elderly in South Korea are the poorest among OECD countries in 2015. The aim of this study was to explore the health and life of the low-income elderly living in vulnerable areas in a metropolitan city. Methods : Data were collected through in-depth individual interviews with 7 participants from October to November 2015 and analyzed through Colaizzi's phenomenological methodology. The participants were interviewed for over 60 minutes in each person. Results : 7 categories were identified from 17 subcategories: "My life history: sick body," "Living with a sick body," "My poor but precious life," "A sense of distance from the hospital," "Narrowed area of my life," "Thankful for help," and "The village where I have lived my destiny." There is a lack of medical accessibility, mobility, and economic independence for low-income seniors. In addition, full-fledged redevelopment comes to them as violence. Conclusions : The health and life of the low-income elderly in vulnerable areas are products of many social factors, reaffirming the importance of social health.
