Estimating the implicit value of housing assets is a very important task for participants in the housing market. Until now, such estimations were usually carried out using multiple regression analysis based on the inherent characteristics of the estate. However, in this paper, we examine the estimation capabilities of the Artificial Neural Network(ANN) and its 'Deep Learning' faculty. To make use of the strength of the neural network model, which allows the recognition of patterns in data by modeling non-linear and complex relationships between variables, this study utilizes geographic coordinates (i.e. longitudinal/latitudinal points) as the locational factor of housing prices. Specifically, we built a dataset including structural and spatiotemporal factors based on the hedonic price model and compared the estimation performance of the models with and without geographic coordinate variables. The results show that high estimation performance can be achieved in ANN by explaining the spatial effect on housing prices through the geographic location.

While the housing transaction price of Seoul tends to be stagnant or declining in line with the housing market recession since 2007, the jeonse price keeps continual increase. Such flow of jeonse price change has a serious influence on ordinary person's housing stability seriously. Therefore, it is very meaningful in terms of social policy to analyze the trend of recent jeonse price change. This study aims to have an empirical analysis of structural characteristics of the trend of recent jeonse price change. After the review of various previous studies, this study selected housing jeonse price index, non-sold house quantity, jeonse vs. transaction price rate, and housing construction performance as analytical variables, and employed monthly time series resources from January 2007 to April 2011. As a result, when the housing supply reduced, the potential quantity for jeonse market reduced that occurred unbalance of supply and demand in jeonse market. In turn, it caused the increase of jeonse price. And, in case of jeonse vs. transaction price rate change, the rate increased which means the increase of required rate of return of invested demand. As such, the increase of market risk degenerates the investment sentiment which caused the reduction of quantity for jeonse market as a submarket.

During COVID-19 the housing market in Korea experienced the soaring prices, despite the decrease in the economic growth rate. This paper aims to analyze macroeconomic determinants affecting housing prices in Korea during the pandemic and find an appropriate statistic model to forecast the changes in housing prices in Korea. First, an appropriate lag for the model using Akaike information criterion was found. After the macroeconomic factors were checked if they possess the unit root, the dependencies in the model were analyzed using vector autoregression (VAR) model. As for the prediction, the VAR model was used and, besides, compared afterwards with the long short-term memory (LSTM) model. CPI, mortgage rate, IIP at lag 1 and federal funds effective rate at lag 1 and 2 were found to be significant for housing prices. In addition, the prediction performance of the LSTM model appeared to be more accurate in comparison with the VAR model. The results of the analysis play an essential role in policymaker perception when making decisions related to managing potential housing risks arose during crises. It is essential to take into considerations macroeconomic factors besides the taxes and housing policy amendments and use an appropriate model for prices forecast.

As a result of supply-oriented housing policy of Korea since the 1960s, the number of apartment housing units has increased up to six million as of the end of 2001 that is 55% of total housing units. Although the needs of placid living environment increases according to the enhancement of residents' living standard, most of construction firms as apartment suppliers plan and design apartment buildings to maximize the profit and give rise the residents' petitions and troubles about floor impact noise. In consequence, the floor impact noise becomes one of principal problems of living environment, and the government placed the obligation of installing the noise isolation materials between upper and lower floors in 2001 and controlling the floor impact noise lower than 60dB from the middle of 2004. In other to provide the fundamental research data to enhance the reduction performance of floor impact sound, in this paper, the factors that influence on the floor impact noise are derived from the survey of many research papers and the performance of various materials used as noise reduction objects are compared and surveyed with the factors in the experiments in field and laboratory.

There have been many requests for development of senior housing in Korea. Therefore it was very important to review how senior houses are established and managed in other countries. In this point, this research compared the actual conditions of the homes for the elderly in the U.K, U.S.A and Japan. Through the process, this research aimed to find the implications for Korea. The research was conducted by the literature review on senior congregate housing with Franklin's(1998) social constructionism perspective. This kind of research might be utilized as a theoretical framework for performance of any systems of housing for the aged. In this study, the researchers suggested the implications of senior congregate housing as follows. Firstly, in terms of structural context, government in the U.K, U.S.A., and Japan were positively concerned with solving the housing problems for senior citizens despite some differences. Secondly, from an institutional context, institutions related with provision, construction, and management of senior congregate housing were systematically consolidated and they all adapted the housing and welfare policy. Thirdly, in organizational context, there was an organization in charge of provision and management that exclusively oversaw the housing for the elderly in both the public and private sectors. Fourthly, in operational context, standards regarding space were clearly set both for individual units and common spaces as well as for facilities and services for the residents. Finally in terms of intersubjective context, the competency of housing manager and ways to involve the families which were important for residents' independent life were under study.

Since the village maintenance type public housing project was introduced in 2015, the resident needs for regional revitalization and pleasant living conditions are not being met due to the poor performance of the public housing complexes that reflect the surrounding area maintenance plan (village plan) and regional characteristics. The purpose of this study is to suggest a plan to revitalize the village maintenance type public housing project in consideration of regional characteristics as a result of analyzing the needs of local residents through the problems of the village maintenance type public housing project being promoted so far and resident satisfaction. As a result of the analysis based on the public housing project implementation status analysis and resident satisfaction, the plans to activate the village maintenance type public housing project are as follows. First, in order to secure the effectiveness of the village plan, it is desirable to promote the public housing project and the village plan at the same time. It is necessary to secure a budget according to the selection of public offering projects in the village plan, such as promoting public housing projects without setbacks by prioritizing land purchases for public housing sites and establishing specialized strategies considering regional characteristics. Second, a public housing project that responds to local demand is required. The evaluation factors such as continuous promotion of the urban architecture integration plan and strengthening of regional linkage plans such as specialization of regionally tailored designs should be supplemented so that regional resources and village plans are linked with the public housing specialization plan. Third, surrounding area maintenance plan (village plan) should be secured by the strengthen of the legal status or establishing related provisions. It is also necessary to promote system improvement for area maintenance plan (village plan) when selecting a publicly funded public project.

The purpose of this study is to analyze the efficiency of the policy direction to see if the government's purpose of relocating public institutions was achieved by analyzing the case of the Korea Housing Finance Corporation, which moved to Busan Metropolitan City in 2014. Based on the Korea Housing Finance Corporation's settlement management disclosure and public institution performance evaluation report from 2009 to 2019, efficiency was compared and analyzed using DEA analysis, work efficiency in management performance evaluation report, and financial ratio. The analysis results are as follows. First, in the case of DEA analysis, the difference in efficiency before and after fat transfer was not noticeable. Second, the efficiency analysis using the performance evaluation report and the financial ratio showed that the efficiency decreased after local relocation. Taken together, in the case of the Korea Housing Finance Corporation, efficiency decreased after local relocation, which can be attributed to sluggish business performance and inefficiency related to financial ratios. However, this study has limitations because it conducted an analysis on the Korea Housing Finance Corporation. To compensate for this, it is necessary to diversify the scope of research targeting all fund-managed quasi-governmental institutions in Korea. Nevertheless, this study is the first study to analyze before and after the relocation of fund-managed quasi-governmental institutions, and is expected to provide significant implications for future policies to be discussed.
