  • Risk management at an early stage of projects is known as an effective method expected various benefits. The PDRI(Project Definition Rating Index) by the CII(Construction Industry Institute) is defined project scope for reducing risks. In addition, the PDRI is one of the verified methods for achieving benefits by a risk management. The literature review in Korea about risk management is all about focusing on construction works and the construction phase. Thus, we need to extend the perspective of a project management such as the PDRI. To develop the Korean PDRI, However, we have to consider Korean situations. Therefore, in this study, we analyze some previous studies of PDRI' indexes and its using methods, and suggest the new direction for using PDRI in Korea.

  • Many studies have focused on the prediction of corporate credit rating using various data mining techniques. One of the most frequently used algorithms is support vector machines (SVM), and recently, novel techniques such as SVM+ and SVM+MTL have emerged. This paper intends to show the applicability of such new techniques to multi-classification and corporate credit rating and compare them with conventional SVM regarding prediction performance. We solve multi-class SVM+ and SVM+MTL problems by constructing several binary classifiers. Furthermore, to demonstrate the robustness and outstanding performance of SVM+MTL algorithm over other techniques, we utilized four typical multi-class processing methods in our experiments. The results show that SVM+MTL outperforms both conventional SVM and novel SVM+ in predicting corporate credit rating. This study contributes to the literature by showing the applicability of new techniques such as SVM+ and SVM+MTL and the outperformance of SVM+MTL over conventional techniques. Thus, this study enriches solving techniques for addressing multi-class problems such as corporate credit rating prediction.

  • Purpose: This study tries to explore experiences with a special rating dementia service among family caregivers of elderly people with dementia. Methods: The participants were 11 family caregivers of elderly people with dementia and had used a day-care service from the special rating dementia service for more than 3 months. Data were collected through individual in-depth interviews and analyzed using content analysis. Results: Three categories emerged: "reminiscence of an entangled life", "feeling relieved from a stifled life", and "hope for a better life through help and support" with 8 sub-categories and 23 codes. By using the special rating dementia service, the participants experienced relief from the burden of caring for their elderly family member with dementia and restored their social relations or family relationships. They experienced a positive transition in which their caring for elderly family members with dementia was integrated into their daily lives, and they expressed their desires for better policies. Conclusion: These findings imply the importance and necessity of the special rating dementia service. Practical and systematic family support programs are necessary and proactive publicity activities by the government and public agencies are suggested to ensure that family caregivers can easily use the special rating dementia system.

  • Road traffic noise level and railway noise level are important factors on apartment inhabitant's comforts. The measurement methods which noted by Ministry of Construction & Transportation(MOCT) and Ministry of Environment(ME) are used for measurement of exterior noise at apartment houses. But these methods are out of date because the height of apartment houses have increased dramatically and owing to the sampling methods of the measurement time interval, rating values are induced differently due to sampling methods. In this study, the sound level of each floor of apartment houses is measured and compared. And rating value due to sampling methods are compared. As a result, the KS outline of 'Field Measurement of Exterior Noise at Apartment Housess' is suggested.

  • The objective of this study Is to supply basic data for large reservoir sedimentation research In future and make suggestions to maintain and opera능 the reservoir more of efficiently. At first, previous studios about the estimation of sediment yield rate were reviewed in Korea. And the discharge rating curves of upstream stage gauging stations and the correlation between dam Inflow and stage discharge were analyzed. With the analysis results, the spec유c sediment rate of Soyanggang dam was estimated as 608 m3/km2/yr. It was similar to that of Soyanggang dam feasibility study and 1994's field surveys of the reservoir than that of 1983's field surveys. Because the sediment rating curves were derived under the low discharge conditions, It needs to be checked under the flood conditions. However, the suggested methods such as flowrate analysis and sediment estimation will be useful to the sediment studios In future. Key words . reservoir sediment, sediment yield rate, rating curve, flowrate analysis.
