  • RCC consumes large quantities of natural resources like gravel stone and steel, and there is a need to investigate on an innovative material that utilizes limited quantities of natural resources but should have good mechanical strength. This study deals with the experimental investigation of strength evaluation of cementitious composites reinforced with polyolefin fibers from 0% to 2.5% (with interval of 0.5%), namely Polyolefin Fiber Reinforced Cementitious Composites (PL-FRCC) and developing statistical regression models for compressive strength, splitting-tensile strength, flexural strength and impact strength of PL-FRCC. Paired t-tests (for each PL fiber percentage 0 to 2.5%) bring out that there is significant difference in compressive and splitting-tensile strength when curing periods (3, 7, 28 days) are varied. Also, a strong relationship exists between the compressive and flexural strength of PL-FRCC. The proposed mathematical models developed in this study will be helpful to ascertain the mechanical strength of FRCC, especially, when the fiber reinforcing index is varied.

  • The National Health Promotion Fund has grown as the increase of tax on tobacco consumption, but more than half of the fund was spent on health insurance supporting. It is important to use the fund appropriately to keep legitimacy and sustainability of health promotion. Therefore, services regarding health promotion should be a priority in spending health promotion fund, and operation system should be established to manage and administer the fund properly.

  • Korea is one of the fastest aging country in the world. The increase in health expenditure is an inevitable problem in an aging country. We examined trend of benefit expenditure in National Health Insurance (NHI) by age group during 2001 to 2016. The benefit expenditure of NHI was 13.0 trillion won (2001) and 48.7 trillion won (2016); that is 3.76 times to 2001. This rapid increase was mostly due to people aged 65 and over. Proportion of beneficiaries aged 65 and over was 6.9% (2001) and 13.7% (2016), benefit expenditure per capita aged 65 and over was 279 thousand won (2001) and 960 thousand won (2016), and utilization days per capita aged 65 and over 21.44 (2001) and 30.23 (2016). This phenomenon was more pronounced in 75 or 85 aged and over. To contain the health costs for older people, the NHI system should be reformed.

  • Until now, Capitalism Problem have been reported by many literature and are recognized which problem cannot be solved this matter. Global organization have been suggested Business ethics to solve Capitalism Problem. Nowadays, Global Excellence Enterprise who already use Business ethics, who well know Business ethics are powerful Competitive factor for Enterprise to survive. It is necessary to apply Business ethics which is Appraisal Model for Business ethics. In this paper, we suggest Appraisal Model for Business Ethics Evaluation and apply to real fields.

  • The alternative evaluation index (AEI) is developed and applied to determine the priorities of some options for integrated watershed management. Based on the results of continuous simulation model, AEIs of some feasible alternatives are calculated using multicriteria decision making techniques and sustainability evaluation model, DPSIR (Drivers-Pressure-State-Impact-Response).

  • Clustering is one of the leading methods to analyze big data and is used in many different fields. This study deals with Clustering Validity Index (CVI) to verify the effectiveness of clustering results. We compare the performance of CVIs with business applications of various field. In this study, the used CVIs for comparing performance are DU, CH, DB, SVDU, SVCH, and SVDB. The first three CVIs are well-known ones in the existing research and the last three CVIs are based on support vector data description. It has been verified with outstanding performance and qualified as the application ability of CVIs based on support vector data description.

  • Artist-in-residence which gets chances to create by artists' moving and encountering new culture is heightening its level in 21th century. Under the circumstance that issue of cultural diversity and the role of artists which is for city revitalization and sustainability are affect residency program in the midst of highly proceeded globalization that international exchange. Therefore, in the aspect of creative city, a new model is creating by reuse of abandoned industrial facilities and Asia or Eastern country become the subject in residency program management, the issue of cultural diversity is getting more important, programs based on project not just residence are managing. Furthermore, it has inter-country cooperating system in the rage of cultural management. It means that artists' space of creating activity has a new, social role in spontaneously we need to approach to following model in Korea, as well.

  • Bridges are critical and valuable components in any road and rail transportation network. Therefore bridge remediation has always been a top priority for asset managers and engineers, but identifying the nature of true defect deterioration and associated remediation treatments remains a complex task. Nowadays Decision Support Systems (DSS) are widely used to assist decision makers across an extensive spectrum of unstructured decision environments. The main objective of this research is to develop a requirements-driven methodology for bridge monitoring and maintenance which has the ability to assess the bridge condition and find the best remediation treatments using Simple Multi Attribute Rating Technique (SMART); with the aim of maintaining a bridge within acceptable limits of safety, serviceability and sustainability.

  • The purpose of this study is to suggest a practical way to measure and report corporate social performance as public interest in corporate social value pursuits increases. In particular, we will look for ways to measure and report on the financial and social performance of a company based on the concept of the Double Bottom Line (DBL), which has recently spread to big companies. For this purpose, this study analyzed the theoretical background and practical techniques related to measuring and reporting corporate social performance, and examined methods for measuring and reporting social performance in the existing financial performance measurement system. As a result, SROI was the most suitable method for measuring social performance of a company. It is recommended that social performance reporting follows the disclosure method of the accounting system, and the details of reporting suggest that using the standard of GRI Standard, an international standard related to sustainability reporting, is the most reasonable alternative to 'Double Bottom Line' performance reporting.
