This study investigates income support, labor opportunities, and social capital by the demographic characteristics of the elderly who participate in the elderly job project, and especially the relationship between social and quality of life. We want to provide empirical data on how the elderly vocational business ultimately affects the lives of the elderly through the intervention of social capital. The intervention effect of social capital is as follows. Satisfaction with the elderly job project has a great impact on the quality of life, trust, network, and social participation. In particular, trust in the quality of life of the elderly had a great influence on the quality of life and was indirectly effective. In addition, the intervention of social participation between social capital was known, and the elderly job project increased social participation to improve the quality of life of the elderly. Therefore, it can be evaluated that the elderly job project has an important positive effect on the quality of life of the elderly, and the social capital formed through the elderly job project plays a role in directly or indirectly improving the quality of life of the elderly.

Objective : This study was conducted to investigate the stress, anxiety, depression, and quality of life that parents of children with disabilities have according to their general characteristics and determine the correlation between stress, anxiety, depression, and quality of life. Methods : The subjects were 242 parents of children with disabilities under the age of 13 receiving treatment at rehabilitation centers for the disabled, rehabilitation hospitals, and child development centers located in D, B, and U metropolitan cities. Results : According to the result of analyzing the correlation between stress, anxiety, and depression that the parents of children with disabilities felt and the quality of their lives, the quality of their lives correlated negative with their stress, anxiety, and depression. In the case of the results according to the parents' general characteristics, stress showed a significant difference depending on the education level, monthly income, and anxiety showed a significant difference depending on child rearing time, occupation, and public transportation. Additionally, depression and the quality of life had a significant difference depending on child rearing time, education level, occupation, and monthly income. Conclusion : The results of this study identified the importance of the mental health of the parents of children with disabilities and the correlation between their mental health and quality of life. Social distancing and quarantine rules that children with disabilities must follow have limited their opportunities to receive education and treatment, so the influence of stress, anxiety, depression that the parents of children with disabilities who should continue to take care of their children should be considered. Based on these results, it is necessary to develop support services for the parents of children with disabilities for enhancement in their mental health in preparation for other disasters in the future.

Social media platforms have become an integral part of our daily lives, and they generate vast amounts of data that can be analyzed for various purposes. However, the quality of the data obtained from social media is often questionable due to factors such as noise, bias, and incompleteness. Enhancing data quality is crucial to ensure the reliability and validity of the results obtained from such data. This paper proposes an enhanced decision-making framework based on Business Decision Management Systems (BDMS) that addresses these challenges by incorporating a data quality enhancement component. The framework includes a backtracking method to improve plan failures and risk-taking abilities and a steep optimized strategy to enhance training plan and resource management, all of which contribute to improving the quality of the data. We examine the efficacy of the proposed framework through research data, which provides evidence of its ability to increase the level of effectiveness and performance by enhancing data quality. Additionally, we demonstrate the reliability of the proposed framework through simulation analysis, which includes true positive analysis, performance analysis, error analysis, and accuracy analysis. This research contributes to the field of business intelligence by providing a framework that addresses critical data quality challenges faced by organizations in decision-making environments.

The demand for the high quality of utility electrical power has been increasing rapidly in recent years because of today's electrical energy dependent industries and most people's everyday lives based on computer systems. However, electrical power supply conditions to meet this high quality demand becomes more difficult and more due to a large portion of nuclear power plants output in total electrical power supply which normally do not respond to frequency variations, and high peak of air conditioner demands during the summer season. So the rest of power plants should be operated to show the best governor regulation performance to maintain the electrical power frequency quality.

Quality characteristics of Yaksik prepared with glutinuous rice soaked for different time lengths were investigated. Moisture contents increased with the increment of soaking time. In Hunter's color value, the lightness decreased and redness and yellowness increased by the increment of soaking time. Samples prepared with a commercial formula showed increased red and yellow colors due to the addition of caramel sauce. The firmness decreased with the increment of soaking time during storage. However, the samples prepared with 2 hr-soaking were retrograded rapidly. In peroxide value, there were no differences among samples. In microbiological evaluation, samples prepared with a commercial formula had prolonged shelf lives probably due to the preservatives contained. Samples prepared with 6 hr-soaking showed the highest score in sensory evaluation.

The indoor air quality of modern people who work indoors more than 80 percent a day has also become a very important factor in their lives. But most indoor air quality is highly polluted due to energy conservation and lack of ventilation. This can lead to pneumonia, asthma and even lung cancer, which can be fatal to children, the elderly and the elderly. Indoor pollutants are caused by boards, wallpaper, paint, etc. used in interior By producing indoor finishing materials using active alumina gel, which is used as dehumidifier, indoor pollutants will be reduced and the possibility of developing respiratory diseases and lung cancer will be reduced.

In this study, The effects of three different biological activated carbon (BAC) materials (each coal, coconut and wood based activated carbons), empty bed contact time (EBCT) and water temperature on the removal of haloacetic acid (HAA) 5 species in BAC filters were investigated. Experiments were conducted at three water temperatures (5, 10 and 20$^{\circ}C$) 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 HAA 5 species removal in BAC columns. To achieve an HAA removal efficiency 50% or higher in a BAC filter, the authors suggest 10 min EBCT or longer for 5$^{\circ}C$ waters and 5 min EBCT for waters at 10$^{\circ}C$ or higher. The kinetic analysis suggested a first-order reaction model for HAA 5 species removal at various water temperatures (5, 10 and 20$^{\circ}C$). The pseudo-first-order reaction rate constants and half-lives were also calculated for HAA removal at 5, 10 and 20$^{\circ}C$. The pseudo-first-order reaction rate constants and half-lives were also calculated for HAA 5 species removal at 5$\sim$ 20$^{\circ}C$. The half-lives of HAA 5 species ranging from 0.75 to 18.58 min could be used to assist water utilities in designing and operating BAC filters for HAA removal.
