This study aimed to develop an effective decision support system for the locational decision of urban parks through integrating decision analysis techniques with spatial analysis functions of GIS, and by doing so, to improve the efficiency and quality of the decision-making process. The system provides an efficient management process by integrating analysis, alternative generation and evaluation procedures into a coherent system environment. Evaluation criteria used in the system includes Equity, Efficiency, Service population, Land cost, Park ratio buildings, and Connectivity of greenery. The system also improves the efficiency and rationality of the decision-making process by incorporating various decision analysis techniques such as MAUT, AHP, and ELECTRE into a decision-making process. The analysis and decision support methods used in the system can be utilized for the locational decisions of other urban public facilities, and the system can also be expanded to a comprehensive park management system by incorporating general management functions for urban parks.

In this paper, the security characteristics of healthcare institutions were derived through analysis of previous research, and the characteristics and status of small and medium sized healthcare institutions were surveyed through field surveys of small and medium sized healthcare institutions. The security management evaluation model for small and medium sized healthcare institutions was designed and verified based on the security characteristics of small and medium healthcare institutions. For the design, we compared and analyzed existing security management system and evaluation certification system of healthcare institutions. We also confirmed the proposed security management evaluation model and the degree of sharing. In addition, we conducted validation for the statistical verification of the proposed security management evaluation model for small and medium sized healthcare institutions, and we performed the relative priority analysis through AHP analysis to derive the weight for each item. The result of this study is expected to be used as a standard of security management evaluation model that can be practiced in small and medium sized healthcare institutions.

The rapid development of information communication technology(ICT) is born opportunities of business venturing and many items of start-up. On the smart media era, there are a lot of location based services. Thus we researched to find which factors impact location based constructs on smartphone environment in this study. We have conducted a preference analysis of the influencing factors for location based constructs for our study. In first steps, based constructs that were already known by empirical studies were categorized information, entertainment, safe&emergency, navigation&tracking and advertising&commerce. In second steps, the preference relationship among the categorized constructs were analyzed using AHP(analytic hierarchy process) technique. Participants of this study were 106 students H university in Daejeon-city during 2014. 10. 11 to 2014. 10. 25. The result of the analysis might be summarized that the chatting(0.170) has the highest preference among the above constructs. Based on these findings, several theoretical and practical implications were suggested and discussed.

Today, there is in the world-wide cognition about RFID technology due to established standard, EPC(Electronic Product Code). RFID technology will have wide influence over various fields. Especially, RFID technology's advantages will have positive influence on logistics field. We can solve limited various problems presented in SCM by applying RFIB technology. We can have higher cantrol system, better benefits and actual decision information. Many organizations, however, still have hesitated now because RFID technology has not been validated and RFID technology is in early stage. Other problems are employee resistance against new technology and lack of academic empirical research on assimilation RFID technology for organization. Above reasons I mentioned make me study on analysis on assimilation RFID technology decision in SCM field. This study attempts to analyze the assimilation RFID technology factor from previous researches by using AHP. This outcomes of study will be helpful when we assimilate RFID technology in SCM fields.

Quality assurance (QA) for nuclear R&D project is very concerned about the poor economy due to the improper selection of QA requirements. This paper proposes a new methodology for determining the relative importance weights of QA requirements considering the attributes of nuclear R&D project. QFD (Quality Function Deployment) is used as a conceptual framework and fuzzy number is introduced to capture the vagueness uncertainty existing in human judgement. Also we use a confidence attitude of decision-maker in order to improve the reliability of extracted attribute level of R&D project. Case study on a nuclear R&D project and scenario analysis are carried out to verify the usefulness and effectiveness of proposed methodology.

Photovoltaic system is the core one among the new and renewable energy of the low Carbon and green growth. Recently, the necessity developing PV is emerging since its of less green hose gas emissions. However, a survey or research on the PV system has been hardly performed. It's not easy to find a appropriate location in consideration of environment. These circumstances encourages a systematic approach for the PV system development. The purpose of this study is to propose a methodology of the location analysis for developing PV system. With this, constraint and location criteria with weights of Analytic Hierarchy Process are established and quantification method of each factor is presented. The location analysis of PV system using the GIS were generalized and the results of analysis for redundant topographic features were presented as 3 criteria of the suitability rank.

Pyeongtaek Port is becoming a specialized for importing or exporting cars. In 2010, Pyeongtaek Port became the major port, out of the 31 ports in Korea, for import and export of cars. Usage of this port was especially high for imported cars. In 2011, more than 1 million cars are expected to be imported or exported via Pyeongtaek Port. This research analyses the factors for selecting Pyeongtaek Port for imported cars and recommendations required to improve Pyeongtaek Port. To do this, questionnaires were given to 14 imported car companies that currently, July 2011, use Pyeongtaek Port and used AHP criteria to asses the importances of each factors. According to this research, the most important determinant for the use of Pyeongtaek Port is 'Port Location' followed by 'Port Cost', 'Port Facility', 'Port Service', 'Port Marketing' and 'Port Cargo Volume', in the order of importance. Also, imported car companies say that the factor in need for the most urgent improvement is 'Port Facilities' in Pyeongtaek Port.

The tasks of Vessel Traffic Services are classified according to the content of the information provided. Since the establishment of the first Vessel Traffic Service center in 1993 at Phohang harbour, it has been steadily developed and its work domain and scope have been expanded. In this paper, the importance and workload of Vessel Traffic Service operators were analyzed according to classification of the tasks. In order to measure the importance and workload, questionnaires were conducted for the operators nationwide, and conclusions were drawn using the multi-criteria decision making process. The relationship between the importance of tasks and the workload might be used as the weights for setting the service areas in the future. Furthermore, it is expected to be used as the data of changable sector operation based on the relationship between importance and workload.

Lately, the three mobile telecom companies in Korea are competing for the launch of internet of things services for using home. Typical launched services are in the smart home related fields. However, internet of things as mobile telecom based are at an early stage, expected that various services will be started continuously. At this point, we have been planning to analyze the preference of Internet of things for objects based on the services already launched. In order to apply the AHP (analytic hierarchy process) analysis method, the first stage factors were designed as safety, security, health care, intelligence and home appliances. In addition, the second stage factors were organized into 18 detailed services presented in the conceptual model. Thus, we present the theoretical and practical implications of these results.
