부동산 시장은 다양한 요인에 의해 가격이 결정되며 거시경제 변수뿐 만 아니라 뉴스 기사, SNS 등 다양한 비정형 데이터의 영향을 받는다. 특히 뉴스 기사는 국민들이 느끼는 경제 심리를 반영하고 있어 부동산 가격에 영향을 크게 미치는 변수라고 판단된다. 본 연구에서는 뉴스 기사의 세분화된 감정 분석을 통해 전통적인 분석 방법보다 더 의미 있는 결과를 얻을 수 있는 부동산 가격 예측 모델을 생성하였으며 뉴스 기사로부터 심리 지수를 산출하기 위해 생성 AI 를 활용하였다. 제안하는 매매가격지수 예측 모델을 통해 부동산 시장과 뉴스 기사와의 관계성에 대해 파악할 수 있으며, 사회/경제적 동향을 반영한 부동산 가격 변동을 예측할 수 있을 것으로 보인다.

This study analyzed annual final sample data from 159 companies based on firms selected as economic justice companies by Economic Justice Institute in Citizens' Coalition for Economic Justice in South Korea according to interest variables from 2005 until 2011. Analyzed results are as follows. First, higher scores in soundness and corporate social activities among CSR items suggested that corporate credit rating upgraded. This indicates that credit rating institutions give a good evaluation on their social activities and reflect them in credit rating assessment. However, environmental protection satisfaction and corporate credit rating showed the opposite results. Second, high objectivity and contribution to the economic development as well as supervision by giant auditors had substantial effects on higher corporate credit rating. In contrast, high soundness and supervision by giant auditors reduced corporate credit rating. Based on this outcome, it is estimated that there is a discriminatory response among CSR activities in terms of credit rating evaluation conducted by credit rating institution.

In this study, we investigated the effects of perceived health and ageism experience of the elderly on successful aging, which were respectively presumed as predictors of biomedical model and psychosocial model of the successful aging. As important research results, firstly, negligence among ageism experience constructs appeared higher than other discriminatory experiences. Secondly, male showed significantly higher discriminatory experience than female in the area of 3 constructs such as property, negligence and employment ageism. Also there were some different discriminative experiences in the area of perceived health and ageism in terms of age, wealth and education. Finally, the results of hierarchical multiple regression hired to find out factors influencing successful aging showed that the factors such as sex, wealth, perceived health and property discrimination of ageism affected successful ageing. Based on the analytic results, we verified that perceived health, i.e., predictor of biomedical model had higher effect on successful aging than ageism experience, i.e., predictor of psychosocial model of successful aging. Thus, it was suggested that health promotion policy should be considered with priority and also combating ageism as well for successful aging.

전 세계적으로 홍수, 태풍, 폭설 등 기상이변에 따른 자연재난이 빈번히 발생하고 있으며, 국내의 경우 연간 약 5천억원 이상의 피해가 발생하고 있다. 미국 및 일본 등의 방재 선진국의 경우 재난 발생 전에 대비하는 재난관리가 중심을 이루고 있으며, 국내에서도 피해가 발생하기 전에 신속하게 재난피해를 예측 및 대비한다면 인명과 재산피해를 최소화 할 수 있을 것이라 판단된다. 따라서 본 연구에서는 신속하게 재난 피해를 예측하기 위해 기존에 함수 개발시 활발하게 사용되었던 다중회귀분석과 최근 이슈가 되고 있는 머신러닝(기계학습)을 활용하여 호우로 인한 피해를 사전에 예측하는 함수를 개발하였다. 행정안전부에서 구축하고 있는 재해연보 자료를 종속변수로 활용하였고, 기상요소 및 사회 경제적 요소를 설명변수로 사용하였다. 본 연구에서 개발된 호우피해 예측함수를 이용하여 호우피해를 예측하고, 이를 기반으로 사전 대비 차원의 재난관리를 실시한다면 자연재난으로 인한 피해를 줄이는데 큰 도움이 될 것으로 판단된다.

고도의 산업화성장에 따라 도시의 기능이 지역간의 완전분리가 아닌 경제적 사회적 상호 연관성이 점점 증가하고 그 내용도 복잡하고 다양해짐에 따라 이에 대한 체계적인 분석이 필요하게 되었으며, 그에 대한 연구 또한 활발히 진행되고 있다. 그러나 기존에 연구에서 제시하고 있는 각 지역단위별로 취업자수에 대한 고용자수 비율 또는 출근통행의 유출량에 대한 유입량 비율 등의 단순지표를 이용한 지역간의 경제적 의존성을 설명하는 데는 한계가 있다고 할 수 있다. 따라서 본 연구는 지역간의 경제적 연관관계 즉 경제적 의존성을 복합적이고 표준화 할 수 있는 계량치로 추정하기 위해 두 변수 집합간의 연관성을 추정하는데 매우 유용한 분석기법인 정준상관분석 기법을 이용하여 추정하고자 하였다. 이에 수도권 72개존의 출근통행자료을 이용하여 지역간의 경제적 의존성을 측정하였으며, 각 존들로 구성된 지역간의 정준상관계수 및 각 존들의 정준가 중계수를 통해 통계적으로 정산되어진 표준화된 계수를 산출하였다. 그 결과 대존의 경우 경기도와 인천시는 각각 0.9753. 0.2968 정도의 서울에 대한 경제적 의존정도를 보이는 것으로 나타나 서울에 대한 경기도의 경제적 의존성이 높은 것으로 나타났으며, 산출된 정준가중계수를 살펴보면 분당구와 서울시의 중구는 서울에 대한 경기도의 경제적 의존성에 가장 높은 영향을 미친 것으로 나타났으며, 또한 중존에 해당되는 인천의 3개 권역, 경기의 16개 권역의 서울 5개 권역에 대한 경제적 의존성도 분석되었다.

Since the first domestic case of COVID-19 in 2020, social anxiety has caused people to avoid going outside, which has resulted in economic damage to alley commercial districts. However, even in the similar commercial districts, the economic impacts were different depending on the characteristics of the alley districts. This study identifies factors that affect the difference in sales of alleyways after COVID-19 by focusing on alley commercial districts in Seoul. Based on the review of previous studies, a total of 42 variables with six characteristics were constructed, and the principal component analysis was used to reduce the dimensionality of mixed variables. The variables were finally reduced to 12 variables and categorized into seven characteristics. We expect that the results of this study can be used as a basis for analyzing sales differences by standardizing the factors influencing sales in market districts that were previously uncategorized.

This study was conducted to explore the factors that affect youth life satisfaction in order to find ways to increase their life satisfaction. For this purpose, we utilized data from the National Youth Policy Institute's '2021 Youth Socio-Economic Survey' to study 2,041 youth aged 18-34 as of 2021. The randomForest method was applied to explore various variables that affect youth life satisfaction. A total of 21 variables were analyzed, including demographic and socio-demographic factors and psychological and emotional factors.The results of exploring the variables affecting youth life satisfaction using randomForest are as follows. First, all 21 predictors were found to have an impact on young adults' life satisfaction. Second, the most significant impact on youth life satisfaction was found to be 'work values'. Third, it can be seen that young people's perceptions of society, such as 'political effectiveness' and 'perception of older generation', are also variables that affect youth life satisfaction. Based on these findings, the variables affecting youth life satisfaction are explained and discussion points are presented.

In this study, death preparation was used as an independent variable, with ego integrity as successful aging used as a dependent variable while depression and death anxiety were used as mediate variables. The purpose of this study is to investigate the differences of the study variables according to the demographic characteristics of the research subjects, and to create a database for developing and improving current educational programs and welfare services to help the elderly achieve successful aging. Two hundred and eighty three elderly people above the age of sixty in Cheongju city were given standardized questionnaires, and the collected data were analyzed. The results of this study are the following. First, the differences of the study variables according to the level of education, health, economy, and social involvement of the elderly are statistically significant. Second, there exists a positive relationship between mental preparation for death and ego integrity (successful aging) while there is no such relation in case of formal preparation for death and ego integrity. Third, depression and death anxiety of the elderly partially mediate ego integrity, which leads to successful aging.

This study empirically analyzed the labor income share of primary and subcontractors. The results are as follows. First, panel regression analysis showed that the variables of transaction concentration, outsourcing cost, capital intensity, and market share had a significant negative effect, while union organization rate and R & D investment had positive effects. In particular, the R & D variable had a negative effect on the share of labor income in the year of investment (t), but had a positive impact on the long-term (t-1, t-2). Second, the share of labor income during the last 11 years (2006~2016) was higher in subcontractors with lower wage levels. This analysis implies that the wage inequality between the primary and subcontracting enterprises can not be eliminated without improving the solvency of subcontractors.
