Considering the fact that quality of life(QOL) conceptually has objective and subjective attributes but difficulties in measuring the subjective aspect cause a number of studies not to be balanced, this study exploits AHP(Analytical Hierarchy Process) which has been used for systematic decision making to include the other aspect. As the first step of the process decision making hierarchy model is set by content analysis of the UNDP QOL index and additional review of previous studies. 'Improving urban QOL' is a goal on top, 'Economical QOL', 'Environmental QOL', 'Social QOL' and 'Physical QOL' are dimensions of sub-goal(means objectives), and further decomposition follows. AHP shows that the dimensions of economical, physical, environmental and social QOL scored higher respectively. The aim of the model is to measure and prioritize the urban QOL in the two case study cities. The final score of the each city could be computed by integration of relative weights of dimensions for urban QOL. The final score of QOL for city A was 0.6642 and for city B the figure decreased to 0.3358. The method of this study could be used in stages of the process of urban planning. First stage is when planners try to have a correct and reliable perspective from the existed conditions of the city. Second stage is when the projects should be investigated to be confirmed for their efficiency. In other words planners can direct the scarce resources towards the aspects of QOL which are more important. And the results revealed that using AHP creates opportunity to involving the different groups in the stage of criteria weighting so that the attitudes of local community could be integrated well to the decision making to be suitable for a new paradigm of participatory and communicative planning.

This study intended to search improvement plan of welfare service based on welfare desire research in order to raise the effectiveness of welfare service for youth in multicultural family. The result of study is that youth in multicultural family has a difficulty in study and home problem. As a result of examination to hierarchy needs in daily life, youth in normal family showed higher desire of membership and love(t=-2.006, p<.05) than youth in multicultural family. Youth in multicultural family showed higher desire of self-realization(t=-4.636, p<.05) than youth in normal family. In result of hierarchy needs of welfare, it is indicated that youth in multicultural family has higher desire of safety(t=7.607, p<.05), desire of membership and love(t=8.346, p<.05), desire of self-respect(t=4.683, p<.05), and desire of self-realization(t=2.199, p<.05). Therefore, welfare service for youth in multicultural family needs the cooperation with community and improvement of speciality of welfare service employees based on unitary integrated system and requires the development of indices to reflect the desire of beneficiary.

One of the core issues in the realization of e-government is the effective implementation of a website. The current trend of e-government is developing individual web sites and portals, covering such fields as education, tax, economics, real estate, travel, and health. Evaluating e-government web sites is essential for improving web sites. These principles can be included in usability in a broader concept. Website usability has attracted considerable research on website evaluation and has been regarded as one of the most important criteria for measuring and evaluating websites. Usable e-government web sites make citizens willing to search for helpful information or solve their civil applications. The objective of this paper is to suggest an Analytic Hierarchy Process (AHP) method for evaluating e-government web sites. The proposed AHP method has two special characteristics compared to general AHP approaches. First, all citizens who are e-government users can evaluate both the usability criteria and the web sites, but the weighting mechanism differs between criteria and web sites. Secondly, a pairwise comparison is time-consuming and not cost effective with many criteria. Therefore for evaluating a website with respect to a sub-criterion, we develop checklist items as measure scales with a seven-point rating. This method is efficient as it enable us to avoid the pairwise comparison mechanism between sub-criteria. A new computation procedure for the AHP is developed that combines and synthesizes priorities of portals in the case that two decision maker groups are involved.

The paradigm of IT ecosystem has been rapidly changing into open ecosystem irrespective of the territory on which the device, software and contents are located. IT venture ecosystem which can compete and collaborate with the global companies is really needed because the global opportunity of IT venture company has been expanding. Research model based on PEST-SWOT-AHP(Analytic Hierarchy Process) model was employed to analyze the current status and problems of IT venture ecosystem in Korea. Survey was conducted with 20 experts who are involved in venture companies, university, R&D research institute, and investment companies as a working group supported by the Ministry of Knowledge Economy (MKE). The empirical result showed that global promotion of IT ventures, coexistence and development of large enterprises and ventures, revitalization of investment infrastructure, and building of smart venture ecosystem are derived to revitalize IT venture ecosystem and suggested global revitalization model for smart IT venture ecosystem.

The objective of this study is to subdivide the tactical considerations (METT+TC; Mission, Enemy, Terrain & Weather, Troops available, Time available, Civil considerations) through Delphi method and prioritize those via AHP (Analytic Hierarchy Process). Though it has been taken for granted that the tactical considerations were inevitable for decision making relating to military operations, their segmentation and priority have not been studied sufficiently in military. The data for Delphi method and AHP were based on interview with military experts and questionnaires answered by those. Six tactical considerations were segmented into 34 sub-considerations by Delphi, and Six tactical considerations and 34 sub-ones were prioritized through AHP in attack and defense aspects. If the research results will be embedded into database of automatic command and control system (e.g. ACTIS; Army Tactical Command Information System), effective decision-making process will get easier and faster.

The paper describes a design process of the connection control function that performs overall procedures of optical network control system in the Next Generation - Synchronous Digital Hierarchy (NG-SDH) based transport system. Here, the NG-SDH means a new SDH technology that could perform automatic connection control with a granularity of VC-3 (about 50M) or VC-4 (about 150M) according to the increase and decrease of traffic, which is different from the existing technology that could perform connection control only with a granularity of a physical SDH link (STM-l, STM-4, STM-16, STM-64, STM-256 etc). The NG-SDH based connection control allows an ingress NG-SDH node to control the appropriate connection establishment process according to connection types such as Permanent Connection (PC), Soft Permanent Connection (SPC), Switched Connection (SC) over various SDH and Ethernet line cards.

This paper designs and implements the management system that can calibrate the contamination vulnerability of the ground water, using an object oriented data model. Geographic-objects are specified by features extracted from an applicable geographic domain, and geographic-fields are defined by chemical factors extracted from each driven water. To show the topological relationships among the geographic-objects and the geographic-fields, this paper attach the weight and the ratio of the drastic model to chemical factors represented on the land use digital map and the ground water digital map. The geographic feature class, administrative boundary class, land use class and driven water class consist of a class composition hierarchy for evaluating the convenient contamination vulnerability calibration with spatial relationships among the well objects. Therefore, this management system for evaluating the contamination vulnerability can also contribute to the application of other natural environments.
