Objective: The goals of this research were (1)to examine the relationship among parental conflict, mothers' depression and preschoolers' sleep problems, and (2) to examine the mediating effects of mothers' depression between marital conflict and preschoolers' sleep problems. Methods: The participants were 1,639 mothers with preschoolers taken from the 5th year Korean Children Panel. Date were analyzed using descriptive statistics, partial correlation analysis, and multiple regression analysis. Results: The results were as follows: First, preschoolers' sleep problems were positively related to marital conflicts. Second, preschoolers' sleep problems were positively related to mothers' depression. Third, marital conflict was positively related to mothers' depression. Lastly, mothers' depression fully mediated the relationship between marital conflict and preschoolers' sleep problems. That is, marital conflict had an effect on preschoolers' sleep problem, only through mothers' depression. Conclusion/Implications: Based on the results, intervention programs should be developed to prevent preschoolers' sleep problems such as marital relationship improvement programs and mothers' depression improvement programs.

Two hundred ten kindergarten teachers participated in this investigation of the relationship between kindergarten teacher's achievement orientation and teacher efficacy. Instruments were the Teacher Efficacy Scale(Lee, 2002) and the Goal Orientation Scale(Lee, 2002). Data analyzed by ANOVA and hierarchical multiple regression analyses revealed that more highly educated and older teachers were more highly oriented toward mastery goals. Teacher high in mastery and in performance orientation exhibited higher efficacy while low mastery oriented teachers were low in efficacy. The influence of performance goal orientation significantly explained the variance in teacher efficacy. The incremental explanation on teacher efficacy by achievement goal orientation after controlling for demographic variables was statistically significant.

The ultimate object of our study is to minimize the release of radioactive material into the environment and to maximize the treatable amount of the generated wastes. In planning the practical operation of the system, however, the operating cost, Process economics and technical flexibility must also be considered. For dealing with these multiple criteria decision making Problems, we used a foal programming which is a kind of multi-objective linear programming. This method requires the decision maker to set goals for each objective that one wishes to attain.

This paper analyses how technological capabilities and entrepreneurship of technology-based start-ups affect their performance. In this paper, a multiple regression analysis was conducted on 248 technology-based start-ups. The effects of indicators of technological capacity like R&D intensity, R&D organization, technology competitiveness, patents, and certification were analyzed. Factors affecting sales were R&D intensity and technological competitiveness. Technology competitiveness and patents were the significant factors influencing product competitiveness. The factor that positively influenced organizational performance, customer performance, and achievement of start-up goals was technological competitiveness. The results of such an analysis should be designed to discover and foster long-term innovation potential, rather than relying on short-term financial performance.

With the proliferation of activity-tracking devices and other smart tools, more users leverage these personal informatics technologies to track their physical and fitness-related activities. The research on the benefits (and limitations) of these devices tends to focus on the use of a single tool, leaving out the interactions among multiple technologies, and how these interactions influence the way users perceive their affordances. Building from an ecological perspective, I extend this research by providing insight into the competitive and complementary relationships among activity tracking devices and other fitness-related and personal informatics technologies within the device ecology of technologies around the user. The affordances of these devices are therefore not enacted in isolation but are relational to understanding of other technological options and differing personal preferences and goals of the user.

Rapid innovation in ICT is transforming the way we work, the way we interact, the way we learn, and the way we live. In the education and training sector, ICT increases access to learning by making it possible for workers to fit their education into family and work schedules and by providing a greater programmatic choice of quality courses. ICT allows multiple workers to simultaneously enrol in training programs and work in their workplace in order to achieve their particular learning goals in a timelier manner. This paper deals with the ICT conditions, role of ICT, application of ICT, and effectiveness of ICT in the area of workforce development.

Tall buildings are built with an abundant amount of materials, including structural materials, coming from our limited natural resources. Tall buildings that began from about 10-story tall office towers have evolved to over 150-story tall mixed-use megastructures. As a building becomes taller, structural material requirement to resist lateral wind loads becomes exponentially larger. Therefore, it is crucial to employ efficient structural systems and optimize their design, which will contribute to sustainable vertical built environments through preservation of resources. Tube type structures with large perimeter diagonals are among the most efficient structural systems for tall buildings. Developments of braced tube, braced megatube, diagrid structures, and their optimal design strategies are reviewed. Superframed conjoined towers, produced by interconnecting multiple clustered braced tubes, are presented as a new design direction to achieve not only structural but also architectural and social sustainable design goals.

This paper proposes a new optimization algorithm prescribed by GBNSGA(Goal-Pareto Based Non-dominated Sorting Genetic Algorithm) whose result satisfies the user's needs and goals to enhance the performance of optimization. Typically, lots of real-world engineering problems encounter simultaneous optimization subject to satisfying prescribed multiple objectives. Unfortunately, since these objectives might be mutually competitive, it is hardly to find a unique solution satisfying every objectives. Instead, many researches have been investigated in order to obtain an optimal solution with sacrificing more than one objectives. This paper introduces a novel optimization scheme named by GBNSGA obeying both goals as well as objectives as possible as it can via allocating candidated solutions on Pareto front, which enhances the performance of Pareto based optimization. The performance of the proposed GBNSGA will be compared with that of the conventional NSGA and weighted-sum approach.

This study aimed to examine the effect of management by objectives(MBO) and job commitment on the nursing performance of operating room(OR) nurses. The study was conducted on 226 OR nurses from tertiary healthcare institutions in Seoul. Multiple regression analysis was performed to determine the effect of OR nurses on nursing performance. In results, the factors that affect the nursing performance of OR nurses included the concreteness of goals, job commitment, and measurability of objectives in that order, and these variables explained 25.9% of the nursing performance. Therefore, in order to improve the performance of the nursing work, it is necessary to make efforts to create a work environment where nursing can be carried out due to the nature of the nursing operation. In addition, it is essential to develop a strategy to further the influence of the concreteness and measurability of goals among other attributes, thereby enhancing the job performance of OR nurses.
