After the spread of the data collection devices such as smart meters, energy data is increasingly collected in a variety of ways, and its importance continues to grow. However, due to technical or practical limitations, errors such as missing or outliers in the data occur during data collection process. Especially in the case of customer-related data, billing problems may occur, so energy companies are conducting various research to process such data. In addition, efforts are being made to create added value from data, which makes it difficult to provide such services unless reliability of data is guaranteed. In order to solve these challenges, this research analyzes prior research related to bad data processing specifically in the energy field, and propose new missing value processing methods to improve the reliability and field utilization of energy data.

As multicultural population has been drastically increasing over the decade in Korea, their quality of life needs to be studied. This study focuses on multicultural youths' suicidal issue in Korea. Suicide is one of the most obvious indicators to show the current status of mental health. Unfortunately, suicide attempt rate of multicultural youths was two-times more than that of non-multicultural youths in Korea during the past two years(2014-15). Through the literature review in Korea as well as the United States, this study explores the related variables to their suicide attempt. Research result says that multicultural youth's suicide is related to a variety of variables, including physical, psychological, educational, socio-economical, and cultural variables. Research implications are as follows: First, these variables can be utilized as predictive or protective factors to prevent their suicide. Second, theoretical framework for comprehensively understanding their suicidal issues needs to be developed. Third, both emergent and normal suicidal interventions need to be provided for multicultural youth in Korea.

Low back disorders (LBDs) have been the most common musculoskeletal problem in Korean workplaces. It affects many workers, and is associated with high costs to many companies as well as the individual, which can negatively influence even the quality of life of workers. The _evaluation of low back disorder risk associated with manual materials handling tasks can be performed using variety of ergonomic assessment tools such as National Institute for Occupational Safety and Health (NIOSH) Revised Lifting Equation (NLE), the Washington Administrative Code 296-62-0517 (WAC), the Snook Tables etc. But most of these tools provide limited information for choosing the most appropriate assessment method for a particular job and in finding out advantage and disadvantage of the methods, and few have been assessed for their predictive ability. The focus of this study was to _evaluate spinal loads in real time with lifting and pulling heavy cow leathers in variety of postures. Data for estimating mean trunk motions were collected as employees did their work at the job site, using the Lumbar Motion Monitor. Eight employees (2 males, 6 females) were selected in this study, in which the load weight and the vertical start and destination heights of the activity remained constant throughout the task. Variance components (three dimensional spaces) of mean trunk kinematic measures were estimated in a hierarchical design. They were used to compute velocity and acceleration of multiple employees performing the same task and to repetitive movements within a task. Therefore, a results of this study could be used as a quantitative, objective measure to design the workplace so that the risk of occupationally related low back disorder should be minimized.

In this study, 150 previous studies of young children's challenging behavior, conducted over the past 10 years, from 2003 to 2012, were selected. These studies were in relation to young children both with and without disabilities, and they were thus used for the purposes of comparative analysis. The major findings are as follows. First, research on challenging behavior not only of young children with disabilities but also of those without disabilities has been an increasing trend from 2008. While most studies of those without disabilities were based on observations by parents or teachers using a variety of tools, studies regarding those with disabilities mainly used single-subject research methods using an operational definition. Second, the bulk of the studies of young children without disabilities were focused on interaction between various children's internal variables and a variety of parent-related variables related to the occurrence of challenging behavior. In comparison, studies of young children with disabilities were focused excessively on direct intervention after the occurrence of problems. Regarding those without disabilities, the interaction between children's temperament, internal variables, and their mothers' parenting behavior, external variables were the main areas of interest for these researchers. There is clearly a growing need for more active research aimed at the prevention of challenging behavior. Challenging behavior in early childhood has an influence not only on each child's present and future academic achievement levels and their quality of life but also on the quality of instruction in classroom available to all children.
