Many construction companies have developed many kinds of information system to integrate the information created in the phase of planning, design, procurement, construction, and maintenance of construction project. However, the previous researches for the state of applying information technologies and the efforts of the analysis of the present information system launched in domestic construction industry is very rare. There also has been short of research on the construction decision-making support theory in construction business and industry. Hence this paper would contribute in identifying the state of information technologies and the theory of decision-making support of the information system in general construction company. and suggest the characteristic model on the information system for the construction decision-making support. The model consists of the two dimensions; (1) organizational hierarchy (2) data analyzing technology. This research, especially, can be expected to initiate the discussion on framework for understanding the construction decision-making support system in construction industry. The model is nut a practical methodology, but a window that offers a new perspective un sources of information system in each construction company, and thus can provide a clue of the useful guide to construction information system development.

The purpose of this study was to investigate the degree of social support, career decision-making self-efficacy, and Job-Seeking Stress of nursing students, and identify influencing factors of Job-Seeking Stress. A convenience sample of 228 nursing students was conducted from in three departments of nursing. Data were analyzed through descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficient, and multiple regression analysis using IBM SPSS 21.0 program. The higher the social support and career decision self-efficacy, the lower the Job-Seeking Stress. The factors influencing Job-Seeking Stress were social support, first hope career, job readiness, career decision-making self-efficacy, and the explanatory power of these variables for Job-Seeking Stress was 19%. Therefore, in order to prevent, cope with, and mitigate the Job-Seeking Stress of nursing students, it is necessary to develop and apply differentiated Career education programs to increase social support and career decision-making self-efficacy.

Knowledge management has been increasingly recognized as important in business management context. Although knowledge management has been proposed as an enabler to reach competitive advantage, little research has considered applying knowledge to business decision-making activities, which may be the main task of enterprise management. The application of knowledge to decision-making has a more significant impact on organizational performance than mere knowledge management for operational level processing. For this purpose, the present study proposes a decision support loop based on the integration of knowledge by adopting a cognitive modeling approach. The proposed model is then discussed, in the real context of an application case.

A CCTV inspection method has been widely used to assess sewer condition and performance, but Korea lacks a proper decision support system for prioritizing sewer repair and rehabilitation (R&R). The objective of this paper is to introduce the results that we have developed in the Sewer Condition Assessment and Rehabilitation Decision-making (SCARD) Program using MS-EXCEL. The SCARD-Program is based on a standardized defect score for sewer structural and hydraulic assessment. Priorities are ranked based on risk scores, which are calculated by multiplying the sewer severity scores by the environmental impacts. This program is composed of three parts, which are decision-making for sewer condition and performance assessment, decision-making for sewer R&R priority assessment, and decision-making for optimal budget allocation. The SCARD-Program is useful for decision-makers, as it enables them to assess the sewer condition and to prioritize sewer R&R within the limited annual budget. In the future, this program logic will applied to the GIS-based sewer asset management system in local governments.

As advance care planning is taking center stage in the field of end-of-life care, various tools have been developed to aid in the often emotional and difficult decision-making process. Video decision support tools are one of the most promising means of assistance, of which the modus operandi is to provide more comprehensive and precise information of medical procedures to patients and their families, allowing them to make better informed decisions. Despite such value, some are concerned about its potential negative impact. For example, video footages of some procedures may be shocking and unpalatable to non-medical professionals, and patients and families may refuse the procedures. One approach to soften the sometimes unpleasant visual of medical procedures is to show less aggressive or more relaxing scenes. Yet another potential issue is that the objectivity of video decision support tools might be vulnerable to the very stakeholders who were involved in the development. Some might argue that having multiple stakeholders may function as checks and balances and provide collective wisdom, but we should provide more systematic guarantee on the objectivity of the visual decision aids. Because the decision of the modality of an individual's death is the last and most significant choice in one's life, no party should exert their influence on such a delicate decision. With carefully designed video decision support tools, our patients will live the last moments of their lives with dignity, as they deserve.

This study attempted to provide basic data for career counseling and education programs by verifying the mediating effect of career decision-making self-efficacy on relationship between perceived social support and career preparation behavior of Korean Polytechnics students. A total of 314 students from 11 departments attending the I Campus of Korea Polytechnics II were surveyed, and the research results are as follows. First, it was found that career decision-making self-efficacy completely mediated the relationship between social support and career preparation behavior. Second, the career decision-making self-efficacy had complete mediating effects on the relation between social support and career preparation behavior. Third, it was found that social support indirectly had a positive effect on career preparation behavior through career decision-making self-efficacy. The results of this study show that perceived social support of Korean Polytechnics students affects career decision-making self-efficacy and increases the level of career preparation behavior. This suggests that through active social support around Korean Polytechnics students, it is necessary to provide environmental factors that can promote career preparation behavior by enhancing the self-efficacy of career decision-making, which is a low-level factor for students.

Many studies in risk management have been focused on management process, contract relation, and risk analysis in the past decade, but very few studies have addressed project risks from the perspective of risk efficiency. This study started with using Fault Tree Analysis to develop a framework for the decision-making support system of risk management from the perspective of risk efficiency, in order for the support system to find risk strategies of optimal combination for the project manager by the trade-off between project risk and cost of project strategies. Comprehensive and realistic risk strategies must strive for optimal decisions that minimize project risks and risk strategies cost while addressing important data such as risk causes, risk probability, risk impact and risk strategies cost. The risk management in the construction phase of building projects in Taiwan upon important data has been analyzed, that provided the data for support system to include 247 risk causes. Then, 17 risk causes were extracted to demonstrates the decision-making support system of risk management from the perspective of risk efficiency in building project of Taiwan which could reach better combination type of risk strategies for the project manager by the trade-off between risk cost and project risk.

Most real world design evaluation and risk-based decision support combine quantitative and qualitative (linguistic) variables. Decision-making based on conventional mathematics that combines qualitative and quantitative concepts always exhibit difficulty in modelling actual problems. The successful selection process for choosing a design/procurement proposal is based on a high degree of technical integrity, safety levels and low costs in construction, corrective measures, maintenance, operation, inspection and preventive measures. However, the objectives of maximising the degree of technical performance, maximising the safety levels and minimising the costs incurred are usually in conflict, and the evaluation of the technical performance, safety and costs is always associated with uncertainties, especially for a novel system at the initial concept design stage. In this paper, a design-decision support framework using a composite structure methodology grounded in approximate reasoning approach and evidential reasoning method is suggested for design evaluation of machinery space of a ship engine room at the initial stages. It is a Multiple Attribute Decision-Making (MADM) or Multiple Criteria Decision Making (MCDM) framework, which provides a juxtaposition of cost, safety and technical performance of a system during evaluation to assist decision makers in selecting the winning design/procurement proposal that best satisfies the requirement in hand. An illustrative example is used to demonstrate the application of the proposed framework.

Objectives: This study is designed to evaluate the influential factors of career decision-making self-efficacy and career identity by health science college students on their job preparation beaviors. Methods: The total 714 questionnaires were distributed to juniors and seniors of health science college, and the result was statistically analyzed through IBM SPSS statistics 20.0. Results: 1. There was no significant difference of job preparation behavior between male students and female students, and while seniors showed highly active job preparation behaviors, those who had high satisfaction level toward their major studies, high academic achievement, and outgoing personality had highly active job preparation behaviors. 2. Students with high satisfaction level toward their major studies, high academic achievement, outgoing personality, and high expected salaries showed high career decision-making self-efficacy level. 3. Students with high satisfaction level toward their major studies, high academic achievement and highly outgoing personality showed high level of career identity. 4. Subsidiary factors of career decision-making self-efficacy were collection of job information, goal setting, planning, and self-assessment, and all of them showed correlation with job preparation behaviors. 5. Among subsidiary factors of career decision-making self-efficacy, "self-understanding" and understanding of job information showed correlation with job preparation behaviors. Conclusion: For improvement on career decision-making self-efficacy and career identity of health science college students, individual support, psychological support, educational support and other supports regarding job employment to provide wide paths and methods for job preparation behaviors are essential, and through various job employment education program and graded counseling, job preparation behaviors shall be promoted as a great strategy.

Research in the decision sciences has continued to develop a variety of mathematical models as well as software tools supporting corporate decision-making. Yet. in spite of their potential usefulness, the models are little used in real-world decision making since the model solution processes are too complex for ordinary users to get accustomed. This paper proposes an intelligent and flexible model-solver integration framework that enables the user to solve decision problems using multiple models and solvers without having precise knowledge of the model-solution processes. Specifically, for intuitive model-solution, the framework enables a decision support system to suggest the compatible solvers of a model autonomously without direct user intervention and to solve the model by matching the model and solver parameters intelligently without any serious conflicts. Thus, the framework would improve the productivity of institutional model solving tasks by relieving the user from the burden of leaning model and solver semantics requiring considerable time and efforts.
