도시 기능구역별 운전자의 가시적 경관이 자동차 교통사고에 미치는 영향 분석 : 해석가능한 기계학습과 음이항 회귀모형의 혼합적 접근을 중심으로
문정훈,이수기 대한국토·도시계획학회 2025 국토계획 Vol.60 No.6
Urban functional zones exhibit distinct patterns of traffic accidents, reflecting variations in spatial configuration and visual landscapes. This study investigates how drivers’ visual landscape elements influence automobile traffic accidents in Seoul. Based on 551,804 Point of Interest (POI) records obtained from Kakao Maps, the city was categorized into four functional zones using Word2Vec embeddings and K-means clustering: high-density residential and educational areas; urban mixed-use activity areas; transit and leisure mixed-use areas; and low-density residential and local living areas. Visual landscape indices, including the Green View Index (GVI), Color Entropy Index (CEI), and Visual Obstruction Index (VOI), were derived from 95,842 Naver Street View images through semantic segmentation and color analysis. XGBoost with SHAP values was used to identify influential variables, followed by negative binomial regression for statistical validation. The results indicate that CEI reduces accidents in high-density residential and educational areas; GVI reduces accidents in urban mixed-use activity areas; VOI increases accidents in transit and leisure mixed-use areas; and GVI increases accidents in low-density residential and local living areas. These findings suggest that the effects of visual landscape elements differ across functional zones, underscoring the need for tailored urban design and traffic safety strategies.

미국 · 중국 · 한국 거시경제변수가 한국 주식수익률 및 변동성 지수 변화율에 미치는 영향 분석
문정훈,한규식 강원대학교 경영경제연구소 2024 Asia-Pacific Journal of Business Vol.15 No.1
Purpose - This article analyzes the impact of macroeconomic variables of the United States, China, and Korea on KOSPI and VKOSPI, in that United States and China have a great influence on Korea, having an export-driven economy. Design/methodology/approach - The influence of US, China, and Korea interest rates, industrial production index, consumer price index, US employment index, Chinese real estate index, and Korea's foreign exchange reserves on KOSPI and VKOSPI is analyzed on monthly basis from Jan 2012 to Aug 2023, using multifactor model. Findings - The KOSPI showed a positive relationship with the U.S. industrial production index and Korea's foreign exchange reserves, and a negative relationship with the U.S. employment index and Chinese real estate index. The VKOSPI showed a positive relationship with the Chinese consumer price index, and a negative relationship with the U.S. interest rates, and Korean foreign exchange reserves. Next, dividing the analysis into two periods with the Covid crisis and the analysis by country, the impact of US macroeconomic variables on KOSPI was greater than Chinese ones and the impact of Chinese macroeconomic variables on VKOSPI was greater than US ones. The result of the forward predictive failure test confirmed that it was appropriate to divide the period into two periods with economic event, the Covid Crisis. After the Covid crisis, the impact of macroeconomic variables on KOSPI and VKOSPI increased. This reflects the financial market co-movements due to governments' policy coordination and central bank liquidity supply to overcome the crisis in the pandemic situation. Research implications or Originality - This study is meaningful in that it analyzed the effects of macroeconomic variables on KOSPI and VKOSPI simultaneously. In addition, the leverage effect can also be confirmed through the relationship between macroeconomic variables and KOSPI and VKOSPI. This article examined the fundamental changes in the Korean and global financial markets following the shock of Corona by applying this research model before and after Covid crisis.

노년층 대상 교육의 변화를 통해 본 박물관의 역할 모색 : 국립중앙박물관 노년층 대상 교육프로그램을 중심으로
문정훈 국립중앙박물관 2018 박물관 교육 Vol.2 No.-
본 연구의 목적은 노년층 대상 교육의 변화를 통해 박물관의 역할을 모색해 보는 것이다. 이를 위해 국립중앙박물관 노인 혹은 노년층을 대상으로 한 교육의 흐름과 현황을 확인하고 참여자의 설문 결과를 바탕으로 박물관이 긍정적인 노년기를 위해 중요한 매개체로서 사회발전에 이바지하고 있음을 확인하였다. 국립중앙박물관은 1949년 교사 대상 교육, 1970년대 관원을 위한 강좌, 1987년 일반인을 위한 프로그램은 노인 강좌로 시작하는데 이는 ‘노인’을 교육 대상으로 분리·인식하였다는 것에 의미가 있다. 노인 강좌의 개설 후 꾸준히 노년층을 대상으로 교육이 이루어졌으며 강좌와 노인과 건강, 전통문화 이론, 문화영화 관람, 고적답사 등 60세 이상의 참가자들은 다른 기관의 노인대학과는 차별화된 과정과 운영에 만족하였다. 2013년부터는 ‘박물관역사문화교실’이 운영되고 있다. 이전의 노년층 프로그램이 일방적 전달식의 강의 중심이었다면 현재의 프로그램은 참여자 중심의 다양한 교육 방식에 노인을 위한 프로그램과 노인에 의한, 노인에 관한 프로그램 등 참여자에 대한 새로운 관점을 적용하고 있다. 이러한 새로운 관점과 접근은 앞으로 변화하는 노년층에 대비한 박물관의 역할을 더욱 강조하고 있다. 현대의학의 발달과 생활수준의 향상으로 인간의 평균수명이 늘어나면서 전 세계적으로 고령화 사회의 노인문제가 심각해지고 있다. 현대의 노인들은 보다 건강한 노년기를 맞이하게 되었으며 박물관·미술관은 사회교육과 평생교육을 담당하는 기관으로 노인을 대상으로 하는 교육을 통해 노인계층에게 자존감 회복과 가족관계 개선 등 삶의 질을 향상 시켜줄 수 있을 것이다. 하지만 박물관 교육이 가지고 있는 고유의 특징과 노년층과의 접점, 유관기관과의 차별성, 새로운 노년층의 진입경로 개척, 운영 방식의 변화 등의 문제가 있기에 체계적인 준비과정을 거쳐 장기적인 계획을 가지고 준비하는 것이 필요하다. The National Museum of Korea operates a lecture program every Wednesday that is open to anyone interested in the humanities. This program developed out of the lectures for adults and senior citizens (e.g., Eunha Culture School) which began before the museum relocated to its present site in Yongsan. After a process of evolution over the years, it has been held under the name “History and Culture Lectures” since 2013. It attracts the largest number of attendees per session among all learning programs under the Department of Education of the National Museum of Korea. The History and Culture Lectures are particularly popular among senior citizens, who make up about 76 percent of total attendees. Roughly 68 percent of the senior participants have attended the lecture program for at least two years, including the lectures held prior to the relocation to Yongsan, and about 99 percent of them report an intention to continue attending the program. These survey results indicate that active participation by senior citizens should continue in the future. In that case, what roles should a museum play for these regular audiences? How should museums view senior visitors? How can museums cope with changes in society? All of these questions require research and new approaches from diverse perspectives.

The Impact of IT Development on Rural Communities in Korea
문정훈,박주원,정구현,최영찬 이화여자대학교 국제지역연구소 2009 Asian International Studies Review Vol.10 No.1
The Internet has brought massive changes to human lives. Among the various positive and negative influences are the rural-urban digital divide, which refers to the information technology gap between rural and urban areas. The Korean government has made several efforts to close this digital divide. The main goal of this study is to identify how the personal and social lives of rural residents are affected by IT development in rural areas, and how the residents perceive the effect of IT development. To accomplish this goal, a survey research was conducted. A questionnaire was developed based on the current body of literature, and used to collect data. The questionnaire was distributed to rural residents in Korea and 272 responses out of a total of 300 collected were usable. Regression analysis methods were used for the analysis. On the analysis where the IT development index was used as an independent variable, positive relationships were found between the independent variables and some dependent variables such as perceived usefulness for jobs, IT usage skills, and tendencies of rural to urban migration. Findings show that rural residents are worried that IT development in rural areas may cause job loss in their respective communities, and decrease social interaction. However, positive perceptions were also apparent, as participants believed IT is useful for communications within the community, as well as better education and medical services.
