교통량이 증가됨에 따라 높아지는 사고율을 줄이기 위해 효율적이며, 다양한 교통 위반 단속이 요구되고 있다. 기존의 유무인 교통법규 위반 단속 시스템의 도입으로 단속 구역 확대를 시도하고 있으나 높은 비용의 문제로 한정된 지역에서만 실시되고 있다. 해당 문제 해결을 위해 본 논문에서는 딥러닝 실시간 객체인식기술을 적용하여 차량의 교통법규 위반을 인식하며 이에 대한 정보를 제공하는 시스템을 개발하였다. 실시간 객체인식 알고리즘인 YOLOv4와 실시간 객체추적기술인 deepSORT 알고리즘을 데스크톱 PC에 적용하여 구현하였다. 개발한 시스템은 과속, 버스 전용 차로, 주정차, 급속 다차선 변경에 대한 인식 결과를 제공한다. 기존 설치된 CCTV 영상을 대상으로 시스템 적용이 가능하여 저비용으로 넓은 지역에 대한 교통법규 위반 상황 인식을 기대할 수 있다.

This study examines the effects of community child care center workers' perception of professionalism on their job satisfaction. This study conducts a survey of 221 community child care workers in Seoul, Gyeonggi, and Gangwon provinces in Korea. Results show that the level of perception of professionalism and job satisfaction are over intermediate. The perception on professional values and ethics are slightly higher than the perception on professional knowledge and skills. The workers are more satisfied with intrinsic job factors such as achievement and responsibility than extrinsic job factors such as compensation and working conditions. Regression analysis reveals that the workers' perception of professionalism is positively associated with both intrinsic and extrinsic job satisfaction. Based on the findings, this study provides suggestions to enhance the workers' professionalism and job satisfaction, which will contribute the quality of services in community child care centers.

The causes and effects of intra-urban spatial inequality have received much scholarly attention. However, the effects of urban spatial inequality on resident perceptions and the mechanisms through which it is sustained and reproduced remain mostly unknown. This study aimed to investigate whether regional deprivation, the relative socioeconomic standing of a region, affects the residents' perceptions of upward social mobility. By employing the ordinal logistic multilevel model to analyze nested data collected from Seoul, South Korea, this study found that the regional deprivation has a significant negative effect on residents' perception of upward social mobility. The results of this study suggest that one way in which spatial inequality is sustained and reproduced is by the effects of regional deprivation, having negative impacts on the aspirations and socioeconomic activities of residents. This study is expected to provide meaningful implications for planning and policy aimed to combat spatial inequality.

한국음식이 미국 내에서 하나의 민족음식으로서 점차 인식되고 있음에도 불구하고, 미국인들이 지각하는 한국음식과 한국레스토랑의 인식과 관련한 연구는 미비한 실정이다. 지금까지 대부분의 연구는 한국을 방문한 외국인들이 지각하고 인식하는 한국음식에 관한 연구에 초점이 맞추어져 왔다. 그러므로, 한국음식과 한국레스토랑에 관한 미국인들의 인식과 한국레스토랑의 포지셔닝(positioning)에 관한 연구는 미국 내에서 한국레스토랑을 운영하는 메니져(manager)들에게 중요한 정보를 제공할 수 있을 것이다. 본 연구는 미국 마이애미 지역의 대학생들을 대상으로 하여 아시안 음식과 레스토랑에 관하여 대학생들이 지각하는 이미지를 확인하였으며, 인지된 대학생들의 아시안 레스토랑과 음식에 관한 이지미는 한국레스토랑의 포지셔닝과 비교분석하기 위하여 도식으로 표현되었다. 그리고 이러한 이미지 포지셔닝 연구는 남부 플로리다(South Florida) 지역에서 한국 레스토랑을 운영하는 메니져들에게 경쟁력 있는 마케팅 전략을 제시해 줄 수 있을 것이다. 따라서, 본 연구의 목적은 미국 마이애미 지역의 대학생들이 한국, 중국, 일본, 베트남, 태국 레스토랑과 음식을 어떻게 인식하고 있는가에 관한 기초 분석연구이다. 각 아시안 레스토랑의 포지셔닝을 확인하며, 본 연구에서 분석된 기초 자료들은 레스토랑 운영자들에게 중요한 마케팅 자료로 제공될 수 있을 것이다.

This study was to identify the differences on cognitions for conservation on the Rice Terraces landscape between local residents and visitors. For this purpose, this study drew problems and implications through consideration about advanced studies and then carried out a survey of local residents and visitors. The results of this study analyzed five factors that are the components of cognition about the Rice Terraces landscape: production, policy, landscape, management, and revitalization. The Cognition of Rice Terraces landscape indicated that local residents had more positive evaluation than visitors did. In addition, there were indicated differences in most items. Particularly, the local residents had more positive evaluation than visitors did in production(rice paddy of fallow ground, form of traditional rice paddy, weeds), landscape(cultural value, footpath of rice field and stonewall), and revitalization(common program for local residents and visitors, village revitalization from festival and event). Visitors had a more positive evaluation than local residents in terms of policy(designation of a place of scenic beauty, direct payment) and management(cooperation of local residents and visitors). In consideration of these results, it needs to draw up measures that are able to build up a common cognition to overcome differences between local residents and visitors. It is based on the knowledge and opinions that visitors and local residents had concerning history, traditions, cultures and production.

Purpose: The aim of this study was to assess the food environment, particularly focusing on restaurants in three areas (Suwon city, Hwaseong Byeongieom-dong, and Bibong-myun). Methods: A total of 662 persons were surveyed on customers' perceptions of the food environment in restaurants. A structured questionnaire composed of 30 questions on 7 factors, sanitation (4 items), displaying information (5), food quality (12), information on nutritional and healthy food choice (6), restaurant's accessibility (1), availability (1), and affordability (1) was used. In addition, an expert assessment of restaurant sanitation, and information on nutritional healthy food choice was conducted through visiting 126 restaurants. Results: Scores (range of score : 1~7) for each factors assessing the restaurant food environment were 5.06 for sanitation factors, 5.05 for displaying information factors, 5.13 for taste appearance factors, and 4.35 for healthy menu factors. Informations on nutritional healthy food choice showed a low rate: only 16.24% of the subjects answered that there is a message encouraging choice of healthy foods and 27.4% answered that menus contain nutritional information. Significant differences in food environment were observed by region (city, town, rural). The restaurants food environment in the rural area turned out to be poorer than that of the other two areas. In comparison of customer perception and expert assessment, significant differences were observed for 'Employee appearances and uniforms are clean and tidy' (p < .05), and 'There is a message encouraging the choice of healthy foods' (p < .05). Conclusion: This study provided evidence for differences of restaurant food environment by regions. In the rural area, there is a problem in restaurant's accessibility, availability, and affordability because of a lack of variety in menu items and restaurants. This results suggest that there is a need for more healthy food restaurants in the rural area.

The purpose of this study is to verify qualitatively and quantitatively practitioners' perceptions of functions and roles of community child center which plays a pivotal role in afterschool care in Korea. To achieve its purposes, we investigate environments, services, workers, service users, and delivery systems of community child center. As a result, 4 types of perception of community child center(service integration-oriented type focusing on professional workers, care-oriented type based on child care center's physical environment, delivering service-oriented type working in collaboration with schools, and individual case management-oriented type) were examined. These results were also classified into two categories. One focused on the importance of workers and supports for service environments. The other focused more on the functions of community child center to find commonality and originality in other afterschool care systems. This study can be valuable in understanding practitioners' different perception on functions and roles of community child center which have not yet been confirmed statistically. The results allow us to apply diverse practitioners' perceptions to the practice, and to elicit discussions regarding improved practice directions for managing community child center. It also can provide useful baseline data in policy decisions and enforcement.

Recently, gesture recognition methods based on dynamic time warping (DTW) have been actively investigated as more mobile devices have equipped the accelerometer. DTW has no additional training step since it uses given samples as the matching templates. However, it is difficult to apply the DTW on mobile environments because of its computational complexity of matching step where the input pattern has to be compared with every templates. In order to address the problem, this paper proposes a gesture recognition method based on DTW that uses localized subset of templates. Here, the k-means clustering algorithm is used to divide each class into subclasses in which the most centered sample in each subclass is employed as the localized template. It increases the recognition speed by reducing the number of matches while it minimizes the errors by preserving the diversities of the training patterns. Experimental results showed that the proposed method was about five times faster than the DTW with all training samples, and more stable than the randomly selected templates.
