Developing Targeted Safety Strategies Based on Traffic Safety Culture Indexes Identified in Stratified Fatality Prediction Models

정소영,Xiao Qin,오철 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.8

The Korea Transportation Safety Authority (KTSA) conducts the special traffic safety culture investigation (STSCI) every year to assist local governments in promoting traffic safety. To address the issue of diversity, the local agencies were grouped into four regions by administrative district unit and offered region-specific safety promotion strategies. However, it is unclear if such a classification truly reflects the underlying differences that contribute to traffic safety. The goal of this study is to identify the most relevant attributes that affect the safety performance of local agencies (called traffic safety culture indexes in the current study) so that targeted safety promotion strategies can be recommended. To accomplish the goal, latent class cluster-based negative binomial regressions were applied for a comprehensive list of factors such as demographics, socio-economic features, roadway conditions, traffic violations and road user driver behavior; resulting in seven clusters of local governments. The following indexes were found to significantly and strongly affect crash fatalities in the clusters: rate of wearing helmet, rate of pedestrian’s signal compliance, the number of unlicensed driving violations, total paved road length, province, ratio of male to female, and population density. Further, stratified negative binomial regression models were developed to identify statistically significant factors for predicting fatal crashes within each cluster. These cluster-specific features allow the KTSA to design targeted strategies for effective safety promotion.

In this study, we compared and analyzed the differences in body composition, physical fitness and dribble skill between twenty two university soccer players and twenty non-athletes. Firstly, it was hypothesized that such a study would reveal some information on the physical condition level of university soccer players. Secondly, it was hypothesized that the differences are in accordance with the position (FW, LK, FB) played. Lastly, it is hoped that such a study will level contribute to the improvement of soccer players physical fitness as well as in soccer performance. 1. Body composition, physical fitness and skill (1) Absoulte lean body mass of soccer players is significantly higher that that of non-athletes(p〈0.01). (2) The agility, 1000M, 50M-dash, vertical jump, dynamic flexibility (power, agility, endurance) and dribble skills of soccer players are significantly different compared with these of non-athletes(p〈0.01). 2. Body composition, physical fitness and skill in accordance with the position. (1) There was no significant difference in the body composition of soccer players according to the position played. (2) The only thing in which significant differences were sech were in the 50M dash, and dynamic flexibility. In the 50M dash, there was significant difference between the performances of FW, and FB, LK and FB. In other words. FW and LK are faster than FB(p〈0.05) . In the case of dynamic flexibility (endurance), that of LK is significantly higher than that of FB(p〈0.05). (3) In the dribble test, there was a significant difference between FW and LK, FW and FB. So, the dribbing of FW is sxcellent among the soccer players(p〈0.05).

Downregulation of MicroRNA-495 Alleviates IL-1β Responses among Chondrocytes by Preventing SOX9 Reduction

Purpose: Our previous work demonstrated that miRNA-495 targets SOX9 to inhibit chondrogenesis of mesenchymal stem cells. In this study, we aimed to investigate whether miRNA-495-mediated SOX9 regulation could be a novel therapeutic target for osteoarthritis(OA) using an in vitro cell culture model. Materials and Methods: An in vitro model mimicking the OA environment was established using TC28a2 normal human chondrocytecells. Interleukin-1β (IL-1β, 10 ng/mL) was utilized to induce inflammation-related changes in TC28a2 cells. Safranin Ostaining and glycosaminoglycan assay were used to detect changes in proteoglycans among TC28a2 cells. Expression levels ofCOX-2, ADAMTS5, MMP13, SOX9, CCL4, and COL2A1 were examined by qRT-PCR and/or Western blotting. Immunohistochemistrywas performed to detect SOX9 and CCL4 proteins in human cartilage tissues obtained from patients with OA. Results: miRNA-495 was upregulated in IL-1β-treated TC28a2 cells and chondrocytes from damaged cartilage tissues of patientswith OA. Anti-miR-495 abolished the effect of IL-1β in TC28a2 cells and rescued the protein levels of SOX9 and COL2A1, whichwere reduced by IL-1β. SOX9 was downregulated in the damaged cartilage tissues of patients with OA, and knockdown of SOX9abolished the effect of anti-miR-495 on IL-1β-treated TC28a2 cells. Conclusion: We demonstrated that inhibition of miRNA-495 alleviates IL-1β-induced inflammatory responses in chondrocytesby rescuing SOX9 expression. Accordingly, miRNA-495 could be a potential novel target for OA therapy, and the application ofanti-miR-495 to chondrocytes could be a therapeutic strategy for treating OA.

To monitor the reproductive patterns of endangered orangutan, Time-resolved fluorescence immuno assay (TR-FIA) were used to analyze metabolites of sex hormones in feces. Orangutan had long-term interbirth intervals (amenorrhea) during lactation period in which the secretion of sex hormones was repressed. The concentration of progesterone in the serum of pregnant orangutan was 30fold higher than that in non-pregnant orangutan. However,the concentration of hCG during pregnant period was different from the result of other primates. The present study suggested that age is not the important factor in determining the reproduction capability, because it is rather greatly influenced by the combination of various factors. Tracing metabolites of sex hormones in orangutan feces seems to be provide the effective solution for the infertility in orangutan. This study result shows the basic data in operating conservation project for endangered orangutan.

조명 변화에 강인한 얼굴인식 방법

PCA(Principal Component Analysis)는 얼굴의 세부 특징을 추출하지 않고, 명도 값으로 표현되는 얼굴 모습 정보를 바로 사용하여 얼굴을 인식하는 편리함 때문에 널리 사용되고 있는 얼굴인식 방법이다. 그러나 이 기법은 조명변화에 민감하다는 단점을 가지고 있다. 따라서 본 논문에서는 이런 단점을 극복하여 조명에 강건한 PCA 기반의 새로운 얼굴인식 방법을 제안한다. 푸리에 변환의 진폭 스펙트럼은 영상의 명도와 관련되며, 위상 스펙트럼은 영상에 존재하는 객체들을 위한 특징 정보를 많이 보유하고 있다는 것은 잘 알려진 사실이다. 따라서 제안방법에서는 PCA를 수행할 때 조명의 영향을 받는 진폭 스펙트럼은 무시하고, 대신에 위상 스펙트럼 정보만을 취하여 PCA를 수행하게 된다. 실험을 통하여 제안방법이 기존 PCA 방법에 비해 다양한 조명 환경에서 우수한 인식률을 보여줌을 알 수 있었다. PCA(Principal Component Analysis), one of the widely-used face recognition methods, recognizes faces by directly operating upon the brightness appearances of the face, without the trouble of extracting the detailed features of the face. However, it has the drawback that it is sensitive to illumination change. Therefore, we propose a new PCA-based approach for face recognition that is resilient to illumination change. It has been well known that the magnitude spectrum of the Fourier transform relates to the brightness of an image, whereas the phase spectrum retains the useful features for the discernable objects in the image. Motivated by this fact, the proposed method performs the PCA algorithm in a way that it takes only the phase component, ignoring the magnitude component that is subject to illumination variations. Experimental results showed that the proposed method yields much better recognition rates than the PCA in a variety of illumination settings.
