신광문,이재수 한국감정원 2019 부동산분석 Vol.5 No.3

The purpose of this study is to analyze the determinants of rent for urban residential housing in Seoul, using general hedonic model and spatial hedonic model, and to compare differences in rent determinants between small housing and general housing and differences in determinants according to analysis methods. The results of analysis show high spacial auto-correlation in rent for urban residential housing in Seoul, which requires the application of a spatial hedonic model for its proper control. High rent for urban residential housing located at ordinary residential areas is judged to result from cheap land price, simple development procedure, and sharing of residential environment infrastructure. Office hotspot and accessibility to bus stop have no significant effects, for bus stops can be a factor in deterioration of residential environment due to noise, traffic accident and particulates. While accessibility to natural environment like park and river acts as an important premium in general housing, they have no significant effects on urban residential housing, because one-person households, two-person households and young people, the main consumers of urban residential housing, satisfy their diverse needs within homes, and thus may not consider surrounding natural environment as important in the selection of residential location. To enhance residential stability for small households as well as improve residential environment for neighborhood residents, it is necessary to make efforts to manage regional housing supply and residential environment comprehensively. 이 연구는 서울시 도시형생활주택의 임대료 결정요인을 일반 헤도닉 모형과 공간 헤도닉 모형으로 분석하고, 소형주택의 임대료 결정요인이 일반주택과 어떻게 다른지, 분석방법에 따른 결정요인의 차이는 무엇인지 비교하는데 목적이 있다. 분석 결과, 서울시 도시형생활주택의 임대료에는 높은 공간적 자기상관성이 관측되어 이를 적절히 통제하기 위해 공간 헤도닉 모형의 적용이 필요하다. 일반주거지에 입지한 도시형생활주택의 임대료가 높은데, 이는 저렴한 지가, 용이한 개발절차, 주거환경 인프라 공유가 가능하기 때문으로 판단된다. 오피스 밀집지와 버스 접근성은 임대료에 유의미한 영향을 미치지 않는다. 버스정류장은 소음, 교통사고, 미세먼지 등으로 주거환경 악화 요인이 될 수 있기 때문이다. 공원, 하천 등 자연환경 접근성은 일반주택에서 중요한 프리미엄으로 작용하나, 도시형생활주택에서는 유의미한 영향을 미치지 못하였다. 주 수요계층인 1 ․ 2인 가구 및 청년계층은 집안에서 다양한 생활의 욕구들을 해결하기 때문에 주거입지를 선정할 때 주변 자연환경을 중요하게 고려하지 않을 수 있기 때문이다. 주민들의 주거환경을 개선하면서 소형가구의 주거 안정성을 높이기 위해서는 지역별 주택공급과 주거환경을 종합적으로 관리하는 노력이 필요하다.

The Seoul Metropolitan Government has launched an urban housing program to help ease the housing shortage in small cities and strengthen the stability of the housing due to the increase in single and double households in the city. In general, a survey of the price premium of local and surrounding environmental characteristics for housing found that little is known to the extent of its impact on housing rents in small and medium cities. We use geographic information system techniques to measure the variables while investigating the impact of these features on monthly rents of urban residential housing by estimating and comparing traditional and spatial header pricing models. We found that spatial HPMs perform better than traditional HPM in terms of fitness. Most of the variables related to location characteristics and the surrounding environment had a significant impact on rent. Rent rates are low in areas near universities. However, access to the park does not seem to be important to residents. We conclude that people living in small urban housing tend to pay rent in different ways.

본 연구에서는 탐구 기능 가운데 자료 수집, 자료 처리, 자료 해석과 관련하여 실험보고서 분석틀을 개발하였다. 또한 개발한 분석틀을 대학생들의 보고서 분석에 적용하여 오차와 불확도 개념을 중심으로 대학생들이 보고서 작성에서 어려움을 겪고 있는가에 대해 알아보았다. 물리실험 수업을 수강한 30명의 학생들에게 실시한 설문지와 학생들이 작성한 실험보고서를 분석하였다. 학생들은 자료 수집과 관련하여 반복 측정에 대해 인식을 하고 있으나 보고서에서는 이를 명확하게 표현하지 못하였다. 극값이나 기울기가 급하게 변하면 더욱 정밀한 측정을 해야 하지만 학생들은 이 부분에서도 어려움을 지니고 있었다. 특히, 오차와 불확도와 관련하여 학생들은 많은 어려움을 표출하고 있었다. 오차와 불확도의 전파에 대한 이해도가 매우 낮은 상태에서 단순한 오차 전파공식도 이용하지 못하는 학생이 많았다. 오차와 불확도를 분석을 통해 자료를 해석하는 과정에서도 많은 어려움을 겪고 있었는데, 오차의 원인들이 결과에 어떻게 영향을 주는지를 정량적으로 분석할 수 있는 학생은 거의 없었다. 반면에 학생 대부분이 오차와 불확도 분석이 중요하다고 응답하였다. 학생들이 중요성을 인식하고 있으나 올바른 개념을 지니지 못하여 보고서 작성에 서 어려움을 겪고 있다는 결론을 내릴 수 있었다. 실험 수업에서 보고서를 통해 과학적 의사소통을 해야 하는 학생들에게 물리 개념뿐만 아니라 자료를 수집하고 처리하고 해석하는 데 필요한 기본 개념에 대한 교육이 필요할 것이다. Analysis frame for undergraduate physics laboratory reports in collecting, processing, and analyzing data was developed. Using the frame and questionaries, we analyzed what difficulties students have in the concepts of error and uncertainty in writing laboratory reports. Students considered repetitive measurement for collecting data, but they didn`t express it distinctly in their reports. They also had difficulties in measuring data around the extreme value or the large slope. Especially, most students have had difficulties with error and uncertainty. They can`t apply the basic formulation to propagation of error and uncertainty. They also had the difficulties in analyzing data with concepts of error and uncertainty. While most students responded that error and uncertainty is important, there were few students who analyzed the influence of the cause of error on the results quantitatively. The result of the study showed that students have difficulties in writing the laboratory reports because they didn`t have the correct concept of the error and uncertainty. So, it is needed to not only teach the physics concept about experiment but to teach basic concept of data collecting, processing, and analyzing specially about error and uncertainty for students as well.

This study aims to analyze the vulnerabilities caused by high temperatures in 18 cities and counties in Gangwon-do. It is also intended to address the use of appropriate vulnerability indicators between absolute or relative indicators. The study also proposes a policy implication for the energy welfare system in Gangwon Province. Vulnerabilities are classified into three environmental groups: climate, population and social, and residential. 18 cities and counties that have been in use for more than 30 years are assessed against national standards, taking into account both the mean and the standard deviation. As a result, eight cities and counties, including Chuncheon and Gangneung, have lower vulnerabilities in the current climate environment, and their general vulnerability is expected to increase sharply in the future. The fragility of population, social and residential environments shows patterns similar to those of climate environments. Evaluating vulnerabilities using absolute values results in conflicting results when compared with results using relative proportions. The former shows a higher vulnerability in urban areas, while the latter represents a higher vulnerability in rural areas. Although some residential areas are vulnerable to high temperatures, energy welfare programs and subsidies have not yet been established. To mitigate the high-temperature vulnerability, legal systems, policies and programs should be prepared that take into account both the population and social environment and the residential environment. in this instance

경주지진이 연립·다세대주택의 매매가격에 미친 영향

This research intends to investigate the effects of 2016 earthquakes on sales prices of both row and multi-family houses in Gyeonju-si in Korea. Attention has been paid to the spatial and temporal impacts on housing sales prices and some policy implications for ensuring residential stability of residential vulnerable groups. As a result of analyzing the spatial effect, the housing sale prices within the earthquake-prone area significantly decreased due to the outbreak of the Gyeongju earthquake. The spatial range of the earthquake is found to be 15 kilometer from the epicenter. There is a significant difference from the spatial distance from the epicenter reported by the Ministry of Public Safety and Security in terms of physical damage assessment. The result of examining the temporal effect shows that the housing sales prices in the earthquake-prone area decreased after the earthquake, but the prices of row and multi-household houses in other areas rose. It is necessary to consider the spatial range of the earthquake in terms of housing market in order to establish housing policies and measures in Gyeonju. It should be also considered that the earthquake-prone area needs long-term housing stabilization measures of more than two years.

포항지진이 저층 공동주택 가격에 미친 시간 및 공간적 효과 분석 - 이중차분법과 다층모형 활용 -

This study analyzed spatial and temporal effects of Pohang earthquake on sales prices of multi-family housing in Korea, where earthquake damage information was not fully known. Factors determining housing prices were examined with a multilevel model and the difference of earthquake effects on housing price was explored with a difference-in-difference method. A random intercept model with two-level variables and interaction terms was finally applied. The spatial effect of housing price was examined because of a big damage of earthquake in Pohang. As a result, the earthquake had a significant effect on low-rise multi-family housing prices in the danger area of an earthquake. The housing prices in the danger area fell 11.8% due to the earthquake. On the other hand, prices in non-danger area rose 7.4%. The increase of housing prices in non-danger area was probably due to residential movements from the danger area. The spatial effect of the earthquake on multi-family housing prices had a range of about 20 kilometers. It was different from the boundary of physical damage caused by earthquakes in the government report. The housing sales prices in the danger area decreased over time. Although such decrease was not statistically significant in terms of temporal effect. After the earthquake, housing prices in the danger area were higher as they became closer to and less dense in terms of population density.
