In this study, the individual vacuum seepage consolidation method, a new soft ground improvement method, was developed to supplement the conventional suction drain method (individual vacuum preloading method) and the geotechnical behavior was predicted through numerical analysis. If the individual vacuum seepage consolidation method applied, the effect of accelerating settlement and increasing the amount of settlement was high when the aquifer was located in the middle or at the bottom of the layer to the target improvement layer. It was found that the pumping amount in the aquifer does not affect the settlement behavior when it exceeds a certain level. Even vacuum pumping wells were installed in various locations, such as inside or outside of the embankment, the difference in settlement and horizontal displacement was insignificant. In addition, it was predicted that the settlement rate was the fastest and the horizontal displacement (inward) was large when both methods were carried out at the same time. Since this method can reach the target settlement amount very quickly, it was confirmed that it is possible to increase the spacing of vertical drain, thereby securing economic feasibility.

This study purposes to examine direct effects of the physical environments and indirect effects of the satisfaction with life on the settlement consciousness of the aged, using the raw data of 2015 Busan Social Survey. The 5,324 cases were selected from the raw data of those more than 65 years old. The results were as following: (1) When age, spouse with/without, diseases with/without, length of residence, and number of communicating persons were controlled, the satisfaction with housing, the number of cultural facilities, and public transportation availability affected directly on the settlement consciousness of the aged, but the levels of the satisfaction with the number of parks were not directly correlated with it. (2) The satisfaction with housing and public transportation affected indirectly on the settlement consciousness through the satisfaction with life. That is, the satisfaction with life had mediating effects on the two variables. (3) The satisfaction with parks did not affect directly on the settlement consciousness, but it affected on the settlement consciousness through the satisfaction with life. That is, the satisfaction with life shows the complete mediating effects on the settlement consciousness. These results imply that the physical environments such as housing, cultural facilities, public transportation affect on the aged's settlement consciousness so that they should be age-friendly.

The landscape of rural settlement incurred the loss and worsening of its main feature in the modernization which was progressed by the inner and outer cause - the growth of urbanization and improvement of living and dwelling environment. This study investigates the visual characteristic of land-use in rural and analyzes relations between visual quantities by land-use and a pre(essence of landscape. And it is suggested the basic data of a planning and a management in rural by making clear characteristics and influences of landscape preference elements The visual characteristic of landscape elements that is based on the rural land-use is classified harmony, variety, variables and particulate. And it is classified the object of landscape by recognizing images of landscape produce space, natural environment, settlement place and cultivated land of a special products. In the analysis of landscape preference, it appears that the harmony has a great influence on a suburban, a rural, a mountainous district, and a hamlet in psychology elements and the volume of forest area in visual elements. As a result, it requests rural scenes in harmony with the natural environment. So, the landscape planning which has the regional development and the identity as the rural settlement can be represented by the preservation and development of regional feature.

In recent days, the safety of the levee has been an issue because the levee has become bigger according to the Four-river Restoration Project and so on. The greater part of the levee damage has occurred in the interface between soils and the structures. Specially, the drainage construction crosses the levee keeps its settlement down in order to secure a grade of drainage. However, when the settlement isn't generated by using foundation such as pile, the levee is more likely to have leakage at the interface because the construction doesn't behave with soils. In our study, therefor, testing of the behavior of the levee having the drainage construction was carried out to clarify the effects of the foundation type of drainage construction.

Simple relationships are proposed in this paper by modifying the Schmertmann's equation for settlement estimations of footings (i.e., $B/L{\approx}1$) carrying vertical loads in saturated and unsaturated sandy soils. The modified method is developed using model plate load tests (PLTs) and cone penetration tests (CPTs) results conducted in saturated and unsaturated sand in a controlled laboratory environment. Seven in-situ large-scale footings tested under both saturated and unsaturated conditions in sands were used to validate the proposed technique. The results of the study are encouraging as they provide reliable estimates of the settlement of shallow footings in both saturated and unsaturated sands using the conventional CPT results.

This study of the living environment for rural residents to identify the relationship between perception and satisfaction are as. Jeollabukdo rural residents survey and SPSS 18.0 statistical program utilizes improvement of rural environment and living conditions were discussed. The main analysis results are summarized as follows. First, rural residents use the facility convenience and accessibility, economic burden, there was a tendency to recognize the important, good natural environment or their children / relatives for the distance was a low awareness. Second, the location and land a job for men, the women have a higher awareness of the use of public transportation inclination showed less than 50 age group showed higher awareness. Third, the rural living environment of residents' satisfaction with 3.544, and overall satisfaction with village life showed a high propensity men have higher satisfaction than women. Finally, the living environment for the perception and satisfaction with the relationship between residential stability and economic awareness of a higher living environment was found that high satisfaction. These findings further improve the rural environment, improve satisfaction in that you can plan the basis for an effective strategy can be. More sustainable in the future, including the analysis of various parameters in progress by being linked to policy measures that will be provided.

A vacuum pressure method has been developed to solve many problems in the conventional surcharge method such as embankments, and its application has increased in the country. Recently, to control target settlements in the field, there have been many studies on the comparison of settlements between vacuum pressure method and surcharge load method in the same conditions. In this study, the settlement characteristics of soil subjected to vacuum pressure and surcharge pressure are discussed. The results indicate that if vacuum pressure is applied to the improvement of soft ground, there will be inward lateral displacement and the vacuum pressure will induce generally less settlement than a surcharge load of the same magnitude. The range of settlement reduction ratio is 0.54~0.67 based on Hooke's law, 0.91 based on field cases, 0.81 based on laboratory oedometer tests, 0.75 based on the theory of elasticity and coefficient of volumetric compressibility and 0.77~0.93 in its recent applications to the thick soft ground.

The purpose of this study is to quantitatively analyze the corresponding residents' benefit to get in the future from the district unit plan of the settlement zone by Cheongju local government. The target districts were selected as Gumdeong-gol district, Juseong district, and Shinmok-gol district, and Hyeonam district which had recently set their district unit plans. Specific targets to be analyzed were some infrastructure including roads, parking lots, parks and others. Using the analysis methods of the Logit model and non-parametric test approach, this study estimated to the average amounts to be willingly paid(WTP) by the residents in targeting settlement zones and tested the reliability of the average amounts of WTP. The results of analysis were as follows. First, it was found that the WTPs for infrastructure under 1st influence area in target districts were estimated as 5,233won for road, 2,826won for parking lot, and 3,705won for park respectively. For the WTPs for infrastructure under 1nd area were estimated as 4,910 won for road, 2,242won for parking lot, and 3,620won for park respectively. Second, as the result of calculating the non-parametric WTP which built the 95% confidence interval, it was found that the all WTPs except the WTP for parking lot were fell into the 95% confidence interval. Third, as the result of calculating yearly total sum of benefits that the residents would get from the 1st influence area and the 2nd influence area, it was found that Gumdeong-gol district were expected to get 62,376,472won-amounted benefits, and Juseong district, and Shinmok-gol district, and Hyeonam district would get 35,0778,016won, 26,886,560won, and 22,252,032won respectively.

This study aims at providing the basic information required for policies on return to countryside for farming or else, through analysing the actual state of settlement and the community of people returning to rural areas. The comparative analysis of people returning toward general village and sub-urban residential complex in rural has been done to figure out the settlement environment. And the status analysis targeting the people returning to rural areas and original residents who live in general village have been done to figure out the actual state of the community. As a result, people returning toward sub-urban residential complex in rural moved for something else, while people returning toward general village in rural moved with the purpose of farming. Like this, the aims of moving into rural areas show difference. There is little conflict between people returning to rural areas and original residents, but some people have an intention to move the other place due to the conflict with original residents. So the community revitalization is needed for the active responses and suitable adaptation of them. On the basis of this study, policy tasks for return to countryside for farming or else were suggested as follows; 1) It is necessary to formulate each policy on return for farming and something else to rural areas discriminatively. 2) The economic support for a stable settlement of people returning to rural areas and the programs activating community with original residents are required. The discussion about the new community formation is needed to respond to the increase of people returning to rural areas.

Background and objective: Rural migrants are an important human resource in urban and rural exchange (URE) business, therefore it is necessary to enhance their awareness and intent-to-participate. This study was to analyze the rural migrants' recognition and intent-to-participate of URE business and to propose the enhancement of them both. Methods: The questionnaire was designed to analyze the socio-demographic background, motivations, satisfaction with settlement, intent-to-persist, and intent-to-participate of URE business including tourism. The data of 144 respondents was subject to the statistical analysis. Results: The motives of migration were to enjoy leisure life after retirement, increased tiredness of city life, health problems, etc. The satisfaction with settlement was 3.67 at 5-point Likert scale. The intent-to-recommend and intent-to-publicize were 3.40 and 3.46, respectively. The intent-to-participate was 3.45, which was affected by the necessity of URE business and the support of central/local governments, and also showed a significant correlation with the satisfaction with settlement, intent-to-recommend, intent-to-publicize, tourism resources for green tourism or rural tourism, driving a car in Namhae county, and the service and price of meals. They thought the missions that the Namhae county office must focus on were to establish an internal/external public relations systems, establish a support system of central/local governments, and foster/support local leaders. Conclusion: It is necessary to improve the satisfaction with settlement and intent-to-persist, expand exchanges with local people, improve internal/external public relations systems, foster/support leaders, improve transportation in the county, enhance the service and price of meals, and develop/operate URE programs including tourism.
