This study presents an analysis of healthcare quality indicators using data mining for developing quality improvement strategies. Specifically, important factors influencing the inpatient mortality were identified using a decision tree method for data mining based on 8,405 patients who were discharged from the study hospital during the period of December 1, 2000 and January 31, 2001. Important factors for the inpatient mortality were length of stay, disease classes, discharge departments, and age groups. The optimum range of target group in inpatient healthcare quality indicators were identified from the gains chart. In addition, a decision support system was developed to analyze and monitor trends of quality indicators using Visual Basic 6.0. Guidelines and tutorial for quality improvement activities were also included in the system. In the future, other quality indicators should be analyze to effectively support a hospital-wide continuous quality improvement (CQI) activity and the decision support system should be well integrated with the hospital OCS (Order Communication System) to support concurrent review.

This study investigated the effects of mothers' perceived social support, stress, and children's temperament on parenting self-efficacy of boy's and girl's mothers among 416 Korean mothers living in Seoul, Korea. Results showed that mothers' parenting self-efficacy of boys and girls were positively related to mothers' perceived social support and children's temperament. On the other hand, parenting self-efficacy of both boys' and girls' mothers were negatively related to mothers' stress. Multiple regression indicated that mothers' perceived social support and children's temperament were the significant predictors for mothers' parenting self-efficacy of boys and girls. Husbands' support, support from social network, approach-withdrawal, and activity level-general were the significant predictors for mothers' parenting self-efficacy of boys. Husbands' support, support from social network, conflict with their children, transition of husband's job, difficulty of finance and business were the significant predictors for mothers' parenting self-efficacy of girls. Husbands' support was the strongest predicator of mothers' parenting self-efficacy of boys and girls.

This article deals with one-dimension backward heat conduction problem (BHCP). A new approach based on least squares support vector machines (LS-SVM) is proposed for obtaining their approximate solutions. The approximate solution is presented in closed form by means of LS-SVM, whose parameters are adjusted to minimize an appropriate error function. The approximate solution consists of two parts. The first part is a known function that satisfies initial and boundary conditions. The other is a product of two terms. One term is known function which has zero boundary and initial conditions, another term is unknown which is related to kernel functions. This method has been successfully tested on practical examples and has yielded higher accuracy and stable solutions.

In this study, seismic performance of various types of valve supports in terms of flexural rigidity are evaluated by FEA using equivalent static load method. Flexural rigidity of the existing two types of valve supports can be effectively improved by simply adding one more bracket on the other side of support. New types of polygonal valve supports with a concept of fully stressed beam theory are suggested and it is verified that the new supports are rigid enough to withstand stronger earthquake which we should be prepared for.

Korea is worldwide top manufacturer of offshore plant industry, while shown weakness in high-valued offshore plant service industry (OPSI). The governmental support policies and studies for fostering programs are centered on shipbuilding and engineering sector. On the other hand, offshore logistics service sector among the programs is neither included as governmental fostering support sectors nor ever-studied. Domestic shipping and logistics companies have many experience of handling various project, heavy-lift cargo and even super blocks on shipbuilding industry. However they are faced with lack of appropriate heavy carrier and others. So for their successful entering into offshore plant logistics market, systematic preparation, studies and supporting policies are highly recommended.

Smart contract, one of the applications of blockchain, is expected to be used in various industries. However, there is risks of damages caused by attacks on vulnerabilities in smart contract codes. Tool support is essential to detect vulnerabilities, and as new vulnerabilities emerge and smart contract implementation languages increase, the tools must have extensibility for them. We propose a design model for extensible architecture of smart contract vulnerability detection tools that detect vulnerabilities in smart contract source codes. The proposed model is composed of design pattern-based structures that provides extensibility to easily support extension of detecting modules for new vulnerabilities and other implementation languages of smart contract. In the model, detecting modules are composed of independent module, so modifying or adding of module do not affect other modules and the system structure.

We study is to confirm the influence of the manager's learning support leadership perceived by the organizational members of small and medium-sized ICT companies on the learning agility and job satisfaction of the organizational members. In addition, this study was to confirm the relationship between learning agility and job satisfaction and the mediating effect of learning agility. To this end, the statistical package program SPSS 24.0 and SPSS PROCESS Macro Model were used for 352 copies. In other words, the results of analysis through frequency analysis, reliability analysis, factor analysis, regression analysis, and bootstrapping method to verify the established research hypothesis are as follows. First, the leadership of the manager's learning support showed a positive effect on job satisfaction. Second, the leadership of the manager's learning support showed a positive effect on learning agility. Third, learning agility was statistically significant in job satisfaction. Fourth, learning agility showed a mediating effect between learning support leadership and job satisfaction. As shown in the results of this study, it was shown that in order to improve the job satisfaction of organizational members, the learning support leadership of the manager and the learning agility of the members can be systematically improved. In other words, in terms of strategic human resource management and strategic human resource development, the organization was required to establish systematic systems and continue to implement them. In particular, there was a need for the development and operation of programs that could develop and improve competency for learning support leadership and learning agility.

The total pollution load management system of watershed has been implemented upon Special Law pertaining to the Han River Watershed Water Quality Improvement and Residents Support, Special Law pertaining to the Nakdong River Watershed Water Management and Residents Support, Special Law pertaining to the Youngsan River Watershed Water Management and Residents Support, and Special Law pertaining to the Seomjin River Watershed Water Management and Residents Support in Korea since 2002. But many other similar systems with total pollution load management system of watershed are being operated separately or independently, even though its purpose is nearly same with those of the total maximum pollutants load management in Law on Water Quality Environmental Protection, environmental impact assessment(EIA) in Law of Impact Assessment on Environment, Transportation and Disaster and Pre-environmental assessment of Environmental Policy Act. Therefore the contents of total pollution load management system of watershed and many other related systems could be overlapped and at some times have inconsistency among them. This study suggests first the integrated operation of total pollution load management system of watershed, EIA, pre-environmental assessment, urban planning, and sewage planning and secondly EIA system development by integration of EIA and pre-environmental assessment and strategic environmental assessment(SEA).
