“…However, when we consider the 42-h time lag data, the correlation coefficient between Seoul_PM 10 _42 and Beijing_PM 10 increased from 0.121 to 0.216, shown in Table 4. This is somewhat supported by the result of Joo et al [11] that the correlation coefficient of a 1-day lag is higher than that of a 0-day lag (same day) across all regions of China. Also, Table 4 shows that Seoul_PM 10 _42 has a positive relationship with Beijing_WS, which implies that Seoul_PM 10 _42 was affected by Beijing factors.…”

“…It is indicated that PM 2.5 concentration in Korea decreased as Chinese emissions decreased. Joo et al [11] analyzed the relationship between particulate matter (PM 10 ) concentrations in seven cities in China and Seoul in Korea using daily data from 2014 to 2017. They used particulate matter concentration in Seoul and seven Chinese cities and showed that the correlation coefficient of a 1-day lag is higher than that of a 0-day lag (same day) across all regions of China.…”

This paper aims to find the relationship between PM10 (particulate matter) concentrations in Seoul and Beijing for a sustainable environment. The influence of Beijing’s PM10 concentrations on those of Korea has been extensively discussed since 2019. Previous studies have presented conflicting opinions on the origin of particulate matter in Korea. Some argued that the particulate matter in Korea had its origin in foreign countries, while others emphasized that particulate matter concentrations in Korea were affected by Korean domestic factors. Thus, we try to answer this controversial question based on actual data. For this, we analyze the correlation between concentrations of particulate matter (PM10) in Seoul and Beijing using hourly data for Shunyi, Beijing and Jung-gu, Seoul from March 2014 to February 2017 and examine how particulate matter in Seoul has been affected by particulate matter in Beijing, taking into consideration wind speed and wind direction, through regression analysis. We hypothesize that particulate matter concentrations in Beijing have affected concentrations in Seoul, and that this would be confirmed if there were a correlation between concentrations of particulate matter in Beijing and concentrations in Seoul when the wind blew from China to Korea. The results of this paper are as follows: (i) When considering the 42-h delay and wind direction, the correlation between Seoul_PM10 and Beijing_PM10 becomes more pronounced. (ii) Regression analysis confirms the influence of Beijing’s factors on Seoul’s PM10 concentrations. (iii) Interaction effects between Beijing PM10 concentration and Beijing wind speed are also identified, indicating a stronger impact when the wind blows more strongly from Beijing. This paper contributes to understanding the dynamics of fine dust in Korea, emphasizing the importance of considering external factors, especially from China.

Background and Objectives：As a predictor of atherosclerosis, the intima-media thickness (IMT) of the common carotid artery (CCA) shows only a weak correlation with the extent of coronary artery disease (CAD). The purpose of this study was to evaluate the hand measured IMT value of the CCA as reliable and strong predictors of the severity of coronary artery atherosclerosis. Subjects and Methods：We performed an ultrasonographic examination of the right CCA by using a 15 MHz linear array transducer in 268 patients (M: F=160: 108, mean age 61.2±10.2) who underwent coronary angiography to evaluate ischemic heart disease. The internal dimension, maximal IMT, irrespective of location and morphology (focal or diffuse), and the IMT of 6 more randomly selected points in the CCA were measured. We classified the plaques as type A (low or equal echo density compared with adventitia) or type B (higher echo density than adventitia). Modified Gensini scores were calculated, as a marker of the extent of CAD, and compared with the results of the IMT examination. Results：Carotid plaques were detected in 156/268 (58%) patients. 119 and 37 patients were types A and B, respectively. The Gensini score was significantly higher in patients with type B (40.6±23.5) than type A plaques (29.3±21.7) (p=0.01). Modified Gensini score was correlated with age (r=0.22 p<0.001), mean IMT (r=0.178, p=0.004) and maximal IMT (r=0.296, p<0.001). After adjusting for age, the maximal IMT was the sole independent variable reflecting the severity of CAD (p=0.001). Conclusion：The maximal IMT, together with the type of CCA plaque morphology, provides more reliable information about the severity of CAD than the conventional mean IMT.
