  • Identifying quality attributes with the greatest value to the residents is important if the Continuing Care Retirement Community (CCRC) is to increase the frequency of residents' dining. However, it is not known which specific attribute is relatively more important than others to evaluate foodservice. The purpose of this study is to identify the relative importance of food and service quality attributes in the evaluation of foodservice in CCRe. This study surveyed the independent living residents of three CCRCs in the Midwestern states. Respondents placed great importance on taste and flavor of food which has the highest percentage of utility range ($28.28\%$) and the second greatest on appearance of the server ($23.46\%$) . The important attributes were ultimately used to predict the most preferred choice of food-service for residents. Knowledge of the importance of the attributes would enable the foodservice managers in CCRCs to manipulate those attributes to enhance the residents' perceptions of quality and identify strategies for continuous improvement.

  • Importance-Performance Analysis(IPA) is a well-known methodology to find the area for improvement. However, the IPA uses different strategies depending on an attribute falls in either 'Concentrate', 'Keep up', 'Possible overkill', or Low priority' quadrant. Problems can occur when attributes locate near the demarcation lines. To solve this problem of IPA, I suggest a modified importance-satisfaction analysis which integrates the Slack(1994)'s diagonal approach and Kano's ASC(Jang et al., 2012) into Yang(2003)'s Importance-Satisfaction model. For this, I investigated 21 smartphone's quality attributes, which adopted from Song and Park(2012)'s study, and conducted a survey of 280 university students for the results of Kano' model and the importance and satisfaction of the quality attributes. The results show that the proposed model enables the business managers to prioritize the quality attributes for improvement through the interpretation on the continuous diagonal line using the Kano's questionnaire only, without acquiring any additional survey for importance of attributes. Accordingly, it is expected that the newly proposed method will diminish the limitation of the existing IPA. In addition, to test the validity of the ASC, this study conducts a comparative analysis between the Kano's ASC and Tontini(2007)'s method to determine the relative importance of quality attributes.

  • This study examines the Critical Success Factors (CSFs) for Mass Rapid Transit (MRT) projects in Bangkok through Public-Private Partnership (PPP) scheme. It measures the relative importance and performance of 22 CSF indicators of PPP for Bangkok's MRT projects and assesses the gap between importance and performance to prioritize the areas for improvement. This study revealed that eight indicators showed lower performance compared to their importance. Based on the gap analysis, the improvement priorities were identified in the following order: sharing information, incorporating technical elements, clarifying the legal framework, stable committee composition, the various finance resources, improved utilization of the PPP act, a transparent procurement process, and tax incentives. The findings of this research offer strategic insights for enhancing guidelines and processes to address the specific challenges in the PPP project, thereby improving the framework and policies necessary for the successful completion of public transportation projects in developing countries.

  • Recently the meaning of the road name address is expended as an information through the revision of the Road Name Address Act. As this revision, the address of things (AoT) become more important indicating the possibility for the expansion to the related business. However, recent study about AoT does not concern how the current priority system works from the first research. In this study, we analyze perception about addressable object between AoT experts and public using AHP analysis. We structured the importance of addressable objects as two categories; urgency and value creation. The necessity in emergency or daily, accessibility and welfare conform the urgency index. Meanwhile, public value creation in public domain or profitability in the business area and economics conform value creation index. We conducted survey for total of 89 of experts and public. The results of this study indicate the relative importance of AoT measured by experts and public. Generally, public tend to concern more about accessibility conforming the urgency index than experts. Moreover, the public WiFi and the sports complex scored the high priority among the remain addressable objects, in respect of the urgency and the value creation. This result could be implemented for the activation of the smart city industry base on the geospatial information including AoT.

  • This research was made to investigate the effects of burned, which is made in the early spring every year at Saebyeol-Oreum from 2003 to 2009, on changes in vegetation on the grassland. The results of analyzing the characteristics of the lay of the land showed that the proportion of the surface land that had the angle of azimuth and the angle of slope in the range of southeast $135^{\circ}{\sim}180^{\circ}$ accounting for 73.89% and $21^{\circ}{\sim}30^{\circ}$ accounting 58.33% of the entire surface land, respectively, was found to be highest. The results of the analysis showed that the relative importance value was found to be lowered from 27.07 in 2003 to 19.47 in 2009, and this can be attributable to the relative importance value of Artemisia japonica having been heightened from 7.07 in 2003 to 16.23 in 2009. The reason that the relative importance value of Artemisia japonica was found to be high is thought to be that vegetation on the surface land was removed by burned in the early spring and, due to this, the dry surface of soil and the high slope accelerated the soil erosion and could not provide proper environment of the growth and development for Imperata cylindrical and Miscanthus sinensis, so Imperata cylindrical and Miscanthus sinensis were excluded and Artemisia japonica whose importance value had been highest have flourished. Researches to maintain the current vegetation on the burned location of Saebyeol-Oreum and to adjust physical characteristics of soil to restore vegetation and the proper time and cycle of burned should be conducted.

  • The purpose of this paper is to select proposed waste facilities sites after consideration of relative importance of siting factors. From the literature review we have established the siting factors affecting selecting waste facilities sites, and constructed hierarchy of siting factors to evaluate the relative importance of the factors using Analytical Hierarchy Process(AHP). After mail surveying of expert group, we have analyzed the relative importance of siting factors affecting waste facilities. We have constructed Geographic Information System(GIS) of raster type, based on seventeen theme maps of siting factors on waste facilities, to select the proposed waste facilities sites after consideration of the relative importance of the siting factors for Gyongsan city, in Korea. After applying linear combination method, and factor combination method to overcome the methodological limitations of land suitability analysis, we have found five proposed sites, where intersected with proposed sites obtained from the two methods. From this research we have found that 1) methodologically, using GIS for selection of proposed waste facilities sites turned out to be highly useful, 2) application of relative importance of siting factors and two methods of land suitability analysis in selection of proposed waste facilities sites are pertinent enough to provide valid and reliable results, and 3) the research methods and approach employed in this research will be highly useful in site selection of other major facilities.
