In this study, The effects of three different activated carbon materials (each coal, coconut and wood based activated carbons), empty bed contact time (EBCT) and water temperature on the removal of pharmaceutical 4 species (oxytetracycline, tetracycline, trimethoprime and caffeine) in BAC filters were investigated. Experiments were conducted at three water temperature (5, 15 and $25^{\circ}C$) and four EBCTs (5, 10, 15 and 20 min). The results indicated that coal based BAC retained more attached bacterial biomass on the surface of the activated carbon than the other BAC, increasing EBCT or increasing water temperature increased the pharmaceutical 4 species removal in BAC columns. In the coal-based BAC columns, removal efficiencies of oxytetracycline and tetracycline were 87~100% and removal efficiencies of trimethoprime and caffeine were 72~99% for EBCT 5~20 min at $25^{\circ}C$. The kinetic analysis suggested a firstorder reaction model for pharmaceutical 4 species removal at various water temperatures (5~$25^{\circ}C$). The pseudo-first-order reaction rate constants and half-lives were also calculated for pharmaceutical 4 species removal at 5~$25^{\circ}C$. The reaction rate and half-lives of pharmaceutical 4 species ranging from 0.0360~0.3954 $min^{-1}$ and 1.75 to 19.25 min various water temperatures and EBCTs, could be used to assist water utilities in designing and operating BAC filters.

In this study, the effect of chronic pain on the lives of elderly people in long-term care service was analyzed based on the mediated effect of depression. The research data was sampled from elderly people in long-term care services, 204 people participated. From mediated regression analysis, depression was the most relevant factor on the quality of life, followed by chronic pain. With chronic pain and depression as independent variables and quality of life as a dependent variable, depression was proved to have had a fully mediated effect on quality of life. The result of this study suggested that convergence of various support systems should be implemented for the elderly in long-term care services.

In order to analyze the impact of fine dust generated from a construction waste intermediate processing site on the surrounding areas, diverse types of samples were collected from inside the site and surrounding areas. The impact analysis results of samples are as follows. (1) Compared to the air quality management standards by the Ministry of Environment, the concentration of fine dust within the site was 30 to 46% for PM10 and 14 to 42% for PM2.5, which was not much different from the general air quality level. (2) It was found that PM10 within the site may have a partial effect on the air quality, but when the blocking facilities in the site, wheel washing facilities at vehicle entry and exit route, and sprinkler during working were maintained, the impact on the nearby area was not high. (3) In the case of PM2.5, its concentration was influenced more by the exhaust fumes from work vehicles than fine dust generated during construction waste processing. Since the PM2.5 concentrations in the site and surrounding area were not much different from the general air quality, there was little correlation with the work impact of construction waste intermediate processing sites. (4) Pb, an indicator of heavy metal components, was within 50ng/m³ in all three sites, which was 10% of the domestic management standard and equivalent to the general air quality level. The complaints from residents in nearby areas were filed using indicators based on visual and experiential information in their daily lives, so even if the survey results of environmental impact by the construction intermediate waste processing site are lower than the standard, nearby residents can feel it better than such numerical information. Therefore, specific activities to reduce find dusts should be continuously continued.

Recently, the frequency of earthquakes is rapidly increasing in Korea. As a result, concerns about earthquakes are increasing. Response and recovery in the event of an earthquake are also important, but it is necessary to identify management vulnerabilities in advance and perform prevention and preparation activities. K-water collects real-time earthquake data by operating an earthquake accelerator to manage facilities safe from earthquakes. In addition, real-time data is transmitted to external organizations. Therefore, various efforts are being made to improve the quality of data. In order to reduce the management vulnerability of the earthquake monitoring system in advance, high-quality data can be produced by minimizing the delay time of data collection and establishing a real-time quality analysis system and base for earthquake data using big data. Accordingly, it is expected to protect the lives and property of the people from earthquake disasters by securing dam safety management and high-quality earthquake data and providing rapid data to external institutions.

In order to understand the variation of air quality and the concentration of atmospheric particulates in Chengdu Second Ring Road renovation project, this paper starts to investigate the surrounding residents' opinions on the influenced environment and their daily lives via questionnaires. Then the study numerically simulates the change rule of atmospheric particulates in terms of time and space by using the Gaussian dispersion-deposition model and the compartment model. The optimized scientific scheme is selected by the improved fuzzy analytical hierarchy process(FAHP) to help decision making for the future urban reconstructions. Finally, the reduced emissions of atmospheric particulates are measured when the improvement scheme is provided. According to the study, it can be concluded that the concentration of atmospheric particulates increases rapidly in central Chengdu city during the renovation project, which results in worsening air quality in Chengdu during March 2012 to March 2013. Taking related measures on energy saving and emission reduction can effectively reduce the concentration of atmospheric particulates and promote economic, environmental and social coordination.

Ascertaining the actual growth rate of the population is an issue that has generated a lot of arguments amongst various scholars in the process of determining the actual census count. As such, this has had a pronounced effect in the determination of the actual growth rates for different urban populations in the country. But the effect centres much when it comes to accurately determining the major components or the factors contributing to the rapid growth of urban populations. The problem of rapid population growth centres much on its effects on the available basic social services and amenities provided for the people in these areas. Factors such as levels of medical knowledge and services, nutrition, quantity and quality of housing etc. to some extent influence the quality and duration of lives of the people. As such, their importance cannot be overemphasized when dealing with the issue of population growth. The study aims to examine the rate of population growth in the Federal Capital City, Abuja with respect to the available public provision of basic social services among other objectives. The findings from the data obtained from the Population Survey conducted in the city in 1985 show that the health care facilities available in the capital city are grossly inadequate to serve the entire inhabitants of the city. Moreso, the volume of in-migration into the city also compounds the health problems facing the city. The conclusion is that there is need for more resources to be allocated to the health sector to guarantee adequate and functional health care services in the city.

Purpose: This study was done to develop the concept of resilience focusing on cancer patients in Korea. Methods: This study was done in three phases sugggested in the Hybrid Model; theoretical phase, fieldwork phase, and analytical phase. Eight cancer patients participated in the fieldwork phase. Results: The antecedent of the concept of resilience was the crisis or adversity that threatens life or changes the quality of life. The attributes of resilience were psychosocial, relational, situational confrontation and faith (philosophical) characteristics. 1) Psychosocial : self worth, self efficacy, self-confidence, independence, optimistic & positive mind, strong will, and responsibility, 2) Relational : relation-oriented, intimacy, and social interests, 3) Situational confrontation : appraisal of stress situation, problem-oriented coping, and ability to applicate a new situation, 4) Faith (philosophical) : the belief that self-knowledge is valuable, finding positive meanings, religious belief, a belief that lives are worthwhile and meaningful, and a balanced perspective of one's life. The consequences of resilience were acceptance of adversity, getting through one's dread and apprehensions, and gratitude & sharing life. The contributing factor of resilience is positive family support. Conclusion: The concept of resilience is necessary in order to manage cancer patients for promoting quality of life so that its application may have a positive impact on the patients care.
