This study aimed at setting up the evaluation indicators system by rural village types to identify systematically the multi-valuedness embedded in rural villages. AHP(Analytic Hierarchy Process) was used for evaluating the relative importance weight evaluation of each indicator and quantitative analysis of rural village through computer works. The importance weight of evaluation indicators was converted into the score on the basis of maximum 1,000 point to increase the practicality. As a result, characteristics of 5 rural village types(Basic life-supporting, Agricultural promotion, Marketing/processing oriented, Urban-rural communication, Life-style choice types) differed in score of classified indicators. Also, These results are expected to be possible to quantitatively evaluate characteristics by rural village types.

With the globalized coming of the knowledge-based society following the post-industrial period, both the crises and opportunities have been occurring together as non-special affairs, which is the same situation in Rural Korea. A crucial key for maximization of potentialities of emerging opportunities is to mobilize the multi-valuedness embedded in rural areas as one of new growth powers. In order to realize a variety of multi-valuedness of rurality, it should be needed to re-discover and re-evaluate rural resources by paradigm shift and to identify the multi-valuedness of resources systematically and scientifically. On the basis of this understanding, this study aimed at setting up the evaluation indicators system by rural village types to identify systematically the multi-valuedness embedded in rural villages in the initial step. Integrated evaluation indicators system was made with 4-level hierarchies; high-leveled one with 3 fields(society, environment, regional economy); middle-leveled one with 8 areas; lower-leveled one with 19 sub-areas; detailed indicators totally with 39 items. These indicators were divided into 12 basic indicators applied to all types and 27 specialized indicators determining the characteristics of village types

Recently, Seismic design criteria for major domestic structures has been being improved constantly, because the importance of seismic design for major public infrastructures is largely recognized. A preliminary assessment of the seismic performance on the existing railway tunnel, a precedent task before conducting a detailed assessment, can be use as the standard of judgement to decide whether to perform a detailed assessment or not. On the other hand, There are no reasonable study in this area. In this study, an assessment method was presented to evaluate a seismic performance of the existing railway tunnels which seismic design are not performed more economically and rationally.

Recently, Seismic design criteria for major domestic structures has been being improved constantly, because the importance of seismic design for major public infrastructures is largely recognized. A preliminary assessment of the seismic performance for the existing rapid-transit railway tunnel, a precedent task before conducting a detailed assessment, can be use as the standard of judgement to decide whether to perform a detailed assessment or not. On the other hand, There are no reasonable study in this area. In this study, an assessment method was presented to evaluate a seismic performance of the existing rapid-transit railway tunnels which seismic design are not performed more economically and rationally.

In this study, considering this construction process, the parametric study is performed and analyzed about factors affecting seismic analysis of cut-and-cover tunnel, such as analysis method(response displacement method, time history analysis method), surrounding soil(in-situ soil or refilled soils), refilled range(d). Consequently, it is hoped to provide the preliminary data for a better reasonable review on seismic design and seismic performance assessment of underground structures.

This paper introduces a HGS(Hybrid Grobal Search) method of cable system identification. This method is based on GA(Genetic Algorithms) and LOA(Local Optimization Algorithm) and combines GA and LOA. GA has a advantage of grobal search and LOA has shown a rapid and accurate solution. It is verified the accuracy and effectiveness of the proposed method through a set of numerical test.

This study was carried out to find out the time-dependent change of central functions in the depopulated rural areas. Three county areas were selected for the case study ; Haenam(as a remote flat area), Goksung(as an intermediate mountainous area), and Hwasun(as a peri-urban area). For each district area administered by each county, service facilities stock was surveyed at both the present('02) and the past('89 or '94)time, and its functional index checked. From the study results, table-tennis rooms, oil shops and inns were ascertained to be disappeared now in the absolute or real terms, while beer halls, restaurants and bakeries to be sharply increased. Generally, in spite of the substantial depopulation in the past decade, service facilities stock has been increased in and concentrated to the highest order center of rural area (county office seated district). However, where this center leans to the outer side of its county area and to the opposite direction against the regional center, the dependent level of service function on the highest center have decreased.
