Providing weather information on roads today means that the road weather conditions near weather observation points are presented to road managers and road users. These weather observation points are managed by the Korea Meteorological Administration. However, it is difficult to provide accurate weather information due to physical limitations such as the presence of precipitation collection points, distance to weather information provision roads, and the presence of mountains. Therefore, this study intends to perform a comparative analysis by time zone and administrative dong provided by the Meteorological Administration using the wiper information among the information contained in the PVD(Probe Vehicle Data) collected from the highway C-ITS project. As a result of the analysis it was possible to detect rainfall even in the event of local rainfall and rainfall over a long period of time and the higher the cumulative precipitation per hour, the higher the probability of coincidence. This study is meaningful because it used PVD to solve the limitations of the existing road weather information provision method and suggested utilization plan for PVD.

This study was a descriptive survey study to confirm the correlation between self-differentiation, Nursing Professionalism, and care efficacy in nursing college students, and to confirm the mediating effect of Nursing Professionalism in the relationship between self-differentiation and care efficacy. The data collection period is from October 30 to November 30, 2022. Data analysis was performed using t-test, Pearson's correlation, and regression methods. Studies have shown that the general characteristics that show significant differences in care efficacy were grade level and major satisfaction. The three variables were statically correlated. In the relationship between self-differentiation and care efficacy, Nursing Professionalism appeared to be a partial mediator (Z=2.196, p<0.05). The partial mediated effect explanatory power was 40%. This study was significant in that it examines the partial mediating effect of Nursing Professionalism in the relationship between self-differentiation and care efficacy for nursing college students, and has prepared the basic data for improving the care efficacy of nursing college students in the future. In the follow-up study, it would be created a program to improve the efficacy of care based on the results of this study and propose an analysis study of its effectiveness. It also proposes a study to expand the number of subjects to identify factors that can affect the efficacy of care.

The marathon has long been established as a representative lifestyle for all ages. With the recent expansion of the Work and Life Balance trend across the society, marathon with a relatively low barrier to entry is gaining popularity among young people in their 20s and 30s. By analyzing the issues and related words of the marathon event, we will analyze the spottainment elements of the marathon event that is popular among young people through keywords, and suggest a development plan for the differentiated event. In order to analyze keywords and related words, blogs, cafes and news provided by Naver and Daum were selected as analysis channels, and 'JTBC Marathon' and 'Culture' were extracted as key words for data search. The data analysis period was limited to a three-month period from August 13, 2019 to November 13, 2019, when the application for participation in the 2019 JTBC Marathon was started. For data collection and analysis, frequency and matrix data were extracted through social matrix program Textom. In addition, the degree of the relationship was quantified by analyzing the connection structure and the centrality of the degree of connection between the words. Although the marathon is a personal movement, young people share a common denominator of "running" and form a new cultural group called "running crew" with other young people. Through this, it was found that a marathon competition culture was formed as a festival venue where people could train together, participate together, and escape from the image of a marathon run alone and fight with themselves.

Copper trihydroxychloride (atacamite, botallackite, paratacamite, etc.), the first green pigment used in Mogao Grotto's mural paintings of China, has been known as "copper green", "green salt", and "salt green", etc. and has been used as an important green pigment with malachite. At first, the natural mineral atacamite was employed, but after the Five Dynasties (907~960 CE), synthetic copper trihydroxychloride was primarily used. In Chinese literature, copper green, green salt, and salt green are recorded as being made via reaction with copper powder, Gwangmyeongyeom (natural sodium chloride), and Yosa (natural ammonium chloride), and the prepared material was analyzed to be copper trihydroxychloride. Copper trihydroxychloride pigment was not found in paintings prior to the Joseon Dynasty (1392~1910 CE) in Korea. In analysis of the green pigments used in paintings and the architectural paintworks in the Joseon Dynasty, copper trihydroxychloride was also shown to have been used as an important green pigment with malachite (Seokrok). In particular, the proportion of copper trihydroxychloride use was high in Buddhist paintings, shamanic paintings, and dancheongs (decorative coloring on wooden buildings). Some of these turned out to be synthetic copper trihydroxychloride, but it is unclear whether the rest of them are synthetic or natural pigments due to a lack of analyzed data. From literature and painting analyses, the pigment name of copper trihydroxychloride in the Joseon Dynasty turns out to be Hayeob, a dark green pigment. It is believed to have first been prepared by learning from China in the early Joseon period (early 15^th century) and its use continued until the late 19^th century with imported Chinese pigment. Round or oval particles with a dark core of copper trihydroxychloride which were used in Chinese literature were similar to the synthetic copper trihydroxychloride pigments used in the Joseon Dynasty and Chinese paintings. Therefore, the synthetic copper trihydroxychloride pigments of Korea and China are believed to have been prepared in a similar way.

The purpose of this research is to find out what factors have an effect on the retailer's performance. Most of the former researches in the similar fields performed their study based on the customers reasons for revisiting or store loyalty. But this research has been done not based on the customer but based on the retailers. It means that the data was collected from individual retailer. Considering the former research and characteristics of the franchisee retailers, size of temporal population around the retailers, visibility of the retailer, competition situation, out-door promotion, street shelf, size of the retailer were selected as factors affecting on the retailers performance. As a performance variable, number of visitors happened to observation period. Data collection was performed through the observation of the retail circumstance and interview with the retailers owner. As meaningful variables affecting on the retailers performance, size of temporal population around the retailers, visibility of the retailer were found in the 5% significance level, and out-door promotion, street shelf, size of the retailer in the 10% significance level, whereas competition situation did not have effect on retailers performance. Finally, we discuss several theoretical and practical implications, and suggest limitations for the research and future research issue.
