Solid and hazardous waste disposal site selection by using GIS(Geographic Information System) is the purpose of this study. The criteria of site selection are usually defined in accordance with geological, cultural and social characteristics. Unadequate adaptation of these criteria in a site selection may cause serious problem of water and soil pollution. The environmental information for extraction of these criteria consist of a lot of data : geology, geomorphology, hydrogeology, engineering geology, cultural and social information.... GIS could be easily applied to construct of this environmental information data base, and carry out cartography simulation using overlay mapping technique(polygon overlay). ARC/INFO(GIS system) was used for these studies, and AML(ARC/INFO Macro Language) in this system provided more variable and effective methods for cartography simulation. TM(Thematic Mapper) images were used for the evaluation of land cover/use in the studied area, by using ERDAS image processing system.

There are increasing interest and need for information on health care consumer with the significance of hospital marketing and strategic planning being increasingly emphasized. This study was conducted to investigate the criteria for selection of medical facilities according to the characteristics of health care consumer by the types of medical services on a sample of 1,500 population aged 20 years and above. Major findings are as follows ; 1. When considering the criteria for selection of medical facilities into two factors, namely, quality or convenience factors, convenience factor was the major contributor for outpatient and dental services whereas it was quality factor for inpatient services. 2. Females and those residing in large cities selected medical facilities based on convenience factor in the outpatient services. In the case of inpatient service, persons who considered their present health status to be good and whose ages were 50 years old and above choose medical facilities based on quality factor. 3. Persons who considered medical facilities to be profit-making tended to choose medical facilities based on convenience factor for outpatient services. There were no differences in the cases of inpatient and dental services. 4. There was no significant difference on the criteria for selection of medical facilities according to the decision maker for selection or trust on medical facilities. On the use of health service information, selection of medical facilities was based on quality factor for those who made more use of the information in the cases of outpatient and dental services. 5. Analysis using the logistic regression model on the criteria for the selection of medical facilities with the characteristics of health care consumer as independent variables was performed. The selection of medical facilities was significantly related with residential area, sex, and use of information on medical facilities for outpatient services and with age, average monthly income, and perception of health status for inpatient services. For dental services significant association with residential area and use of information on medical facilities was seen. The results of this study, despite some limitations, can be used as baseline data for marketing and strategic planning of hospital management.

In the model selection problem, the main objective is to choose the true model from a manageable set of candidate models. An information criterion gauges the validity of a statistical model and judges the balance between goodness-of-fit and parsimony; "how well observed values ran approximate to the true values" and "how much information can be explained by the lower dimensional model" In this study, we introduce some information criteria modified from the Akaike Information Criterion (AIC) and the Bayesian Information Criterion(BIC). The information criteria considered in this study are compared via simulation studies and real application.

Although there has been growing interests in outsourcing the logistics sectors in the industry, not much research was undertaken to provide the processes and standards in choosing the right 3PL for the company. In this research, we attempt to provide the 3PL selection criteria and its priority orders. We surveyed and interviewed the various industry experts and analyzed results using Analytic Hierarchy Process(AHP). The study reveals that manufactures and logistics companies have different understanding of the selection criteria and priorities in outsourcing the 3PL.

This study aimed to provide the basic data of the establishment of marketing strategies by dividing consumer groups in accordance with the pursuit of clothing benefit, and then understanding the importance of clothing selection criteria in those groups, whether there are any differences in it between groups, and whether there are any differences in preference of clothing color depending on the mood state of those groups. The scale of this study was comprised of the pursuit of clothing benefit factors, clothing selection criteria factors, and the factors related to preference of clothing color by each mood state. In the results of the analysis, the factor most considered when male and female consumers in 20s~30s purchase clothing was fitting, and followed by convenience, stable shape, condition, design, and others' reaction in order. However, those 'design', 'convenience', 'others' reaction' and 'condition' factors were significantly different between groups. Therefore, the significance of this study is that fashion brands could develop new positioning maps for marketing and promotional strategies based on the pursuit of clothing benefit shown in this study.
