This study has the purpose of suggesting the method to analyze the spatiotemporal change of satisfaction concerning the officially assessed land price using geostatistical analysis. Analyzing the spatial distribution characteristic of officially assessed land price using present GIS (Geographic Information System) or is staying at qualitatively suggesting the improvement method of the officially assessed land price system. Grouping the appeal strength based on the official price and opinion price of officially assessed land price, GIS DB (Database) was constructed and the time seriate satisfaction were analyzed and compared through spatial density analysis and spatial autocorrelation analysis. As a result, it was found that the difference between the official price and the applicant's price differed depending on individual land, but most of the respondents requested the increase or the reduction of the average land price, which resulted in a large number of request. Analyzing the satisfaction of the officially assessed land price by using GIS, it was known that satisfaction of officially assessed land price could be analyzed by using the difference of the opinion price and not only the officially assessed land price. Spatiotemporal change of officially assessed land price satisfaction was known to be possible through spatiotemporal pattern analysis method such as spatiotemporal auto-corelation analysis and hotspot analysis etc using GIS. In short, regionally positive or negative significant relationship was investigated through spatiotemporal analysis using annual data.

The number of Aged Apartment units is expected to increase as time went on. Living standards are getting better and they want a new apartment space as the economy progresses. Therefore, it is necessary to prepare for the increasing remodeling market through the feasibility evaluation method that can be applied to the remodeling project of the apartment house. The purpose of this study is to analyze the social pricing factors affecting the Officially assessed individual House Price for the analysis model of commercial house remodeling. The collected samples were analyzed using multiple regression analysis of 350 prices included in 127 lots. Middle school level, high school level, total number of households, and floor area ratio were extracted. As a result of comparing the Officially assessed individual House Price by applying to the remodeling case, the difference between the existing Officially assessed individual House Price and the improvement Officially assessed individual House Price is different. The accessibility with the subway station is included in the land price, and there is no change in the number of stories and directions because it is customized remodeling. There was a difference in the disclosure price depending on the type of factor extraction by the evaluator in a batch application of the disclosure price factors. The research can be used as a model for future remodeling business feasibility analysis.

This study aims to analyze the changes (2011→2021) in social and environmental factors, such as actual construction activities, including building development and officially assessed individual land price, of the areas that have been released from the park during the second national park area adjustment period (2010~2011) and compare them with those of the areas that retained parks in the same period to analyze the development impact. In the released area, a building has been constructed per 16,431 square meters since 2011. Moreover, both the number of floors and height of the building has increased, and it was analyzed that the class 2 neighborhood living facilities occupied the highest proportion of the building use. Officially assessed individual land prices increased by 42.3% in the released area and 38.6% in the retained area. The analysis by region showed that the officially assessed land price increased by 55.2% on average in both released and retained areas in Seoul and 9.4% in Gyeonggi-do, indicating a much larger increase in the Seoul region. The issue of private property rights in national parks was mostly resolved as they were released through the second national park area adjustment. However, the Korea National Park needs to promote the benefits of landowners by suggesting rational alternatives such as adjustments to the park zoning and facility planning.

The objective of the study is to analyze the impact of zone adjustment by comparing the changes from 2011 to 2018 of social and environmental factors such as the special-purpose area, actual construction activities including building development, land use environment, and officially assessed individual land price in the areas released from the National Park Zone during the second National Park Zone adjustment during 2010 to 2011 with the social and environmental factors in the areas that remained in the National Park Zone during the same period. We intended to investigate the problems of the second National Park Zone adjustment and explore alternative implications for the third National Park Zone adjustment. As for the special-purpose area, 80.4% of the released areas were converted to planned, production, and conservation area while 15.6% changed to the agricultural area, and 4.0% remained as the natural environmental conservation area. Regarding the change in building development scale, the average size of construction in the released area since 2011 was $106m^2$ while that in the retained areas was $91m^2$. For the land use environment, the rate of change from the natural area to developed area was 1.9% in the released area and 0.7% in the retained area. The officially assessed individual land price increased by 11,911 won in the released area and 4,413 won in the retained area. Although both areas showed an increase in the land price, the difference of officially assessed individual land prices was about 2.5 times. The problem concerning the private property rights of local residents in the national parks is still a challenge, but the second National Park Zone adjustment has resolved the problem significantly. Accordingly, it is necessary to offer the benefits for the residents in the national park area by analyzing the park zoning and park facility planning to present the rational alternative. It is also necessary to establish a support system that encourages the collaborative cooperation between the park authority and residents and assures that the residents to have pride in the national park.

This study empirically analyzed the determinants of the assessment ratio (hereinafter 'AR') based on a total of 2,129 sales cases of forests in Gwangju, Gyeonggi-do. The main findings of this study through multiple regression analysis are summarized as follows. First, this study shows that regional characteristics have significantly different effects on the AR of forest land prices. Specifically, there was a significant difference in the AR depending on the location of the parcel by sub-region and the ratio of residential area, and the higher the number of development plans in progress, the more likely the officially assessed land price will be formed close to the sale price. Second, this study analyzed that location characteristics such as the proximity of the inner and outer center of the jurisdiction and traffic accessibility had a significant influence on the determination of the AR. Third, this study identified significant differences in AR depending on detailed factors such as planning management areas, production management areas, conservation areas for mountain, conservation areas for nature, and restricted development areas as land use and regulatory characteristics of forest lands. Fourth, this study found that land characteristics are a significant factor influencing the AR as an individual factor in forest land.

As of 2017, there are 848 million households living in apartment and 55.87% of Aged apartments over 15 years old. The allowable standard for remodeling the apartment is more than 15 years and the market for remodeling the apartment will continue to increase. For the success of the remodeling project feasibility analysis is important but the existing feasibility analysis of new construction and reconstruction is being used for remodeling feasibility analysis. Therefore, it is necessary to study the feasibility analysis of customized remodeling without increasing the number of households according to the building law. Purpose of this paper is to develop a feasibility analysis methodology for customized remodeling projects by deriving the factors affecting the formation of land prices and building prices in apartment. According to the concept of price formation of the apartment, the analysis method of the customized remodeling of the old apartment using the factors affecting the Land Price Indexes, Officially Assessed Individual Land Price, House Price Indexes, and Officially Assessed Individual House Price was suggested. The Stair Price Algorithm developed in this research can be utilized at the stage of selecting remodeling contractors after the remodeling housing association is established.

Traffic noise pollution is a growing problem that highly affects the health of people in urban areas. In order to implement effective measures against traffic noise the noise mapping about its distribution is imperative. Urban traffic noise maps will help to establish the existing baseline so that we will be able to look for the effective way to control the noise. They will also let us see in an understandable and visual way how noise spreads from roads into residential areas. In this paper we considered three development types between roads and residential areas, and applied the interpolation of ArcGIS for noise attenuation with distance from the roads to find the noise level at the parcels positions in residential areas, and then generated the noise map using the interpolated results. Therefore we present results that the traffic noise level within residential areas exceed the national noise standard and also can estimate the noise level of individual parcels. These results can be used for traffic noise control planning or assessment of officially assessed land price in near future.

This study is to suggest the need to apply appraisal in calculating estimated compensation in order to efficiently implement the national cadastral resurvey project. The results from this research are summarized as follows. First, it is expected that the need to calculate estimated compensation would increase in the near future because current cadstral records do not reflect the reality. Second, the calculation and adjustment of estimated compensation can not be performed by officially assessed individual land price because the true value of a land can not be evaluated on the basis of the individual land price. Third, a variety of evaluation techniques such as individual evaluation and partial evaluation would be required in calculating estimated compensation depending on the type of land. In addition, an expert appraisal would be applied to the calculation of estimated compensation in order to achieve the purpose of fair estimated compensation.

The purpose of this study is to investigate and analyze the cadastral transformation process of Dokdo-ri based on the institutional concept of the cadastre, while presenting the cadastral characteristics of Dokdo-ri therefrom. For this purpose, both the literature search method and the Internet search method were used. As for the analysis method, descriptive analysis method and comparative analysis method were used. The findings support that the cadastral characteristics of Dokdo-ri is drawn as follows: First, from the physical point of view, the cadastral characteristics of Dokdo-ri shows that the territory is given by the smallest lot numbers in the country and that the territory is also given by the land lot number consisting of small size lots without continuing the ground for which the cadastral resurvey project was carried out for the first time. Second, in terms of the rights, the cadastral characteristics of Dokdo-ri shows that the entire area given by the lots is owned by a single owner and no ownership has been changed. Third, in terms of its value, the cadastral characteristics of Dokdo-ri shows that it is the only area given by the lots of which the officially assessed individual land price has never been decreased in the entire lots. Fourth, when it comes to presenting the cadastral characteristics of Dokdo-ri in terms of the use control/restriction, the consciousness of preserving Dokdo-ri and the consciousness of enhancing real territory are confronted but due to the Cultural Heritage Protection Act etc, the cadastre turned out to be a very passive cadastral work.
