This paper presents an analysis on driving safety in lane change situation based on road driving data. Autonomous driving is a global trend in vehicle industry. LKAS technologies are already applied in commercial vehicle and researches about lane change maneuver have been actively studied. In autonomous vehicle, not only safety control issue but also imitating human driving maneuver is important. Driving data analysis in lane change situation has been usually dealt with ego vehicle information such as longitudinal acceleration, yaw rate, and steering angle. For this reason, developing safety index according to surrounding vehicle information based on human driving data is needed. In this research, driving data is collected from perception module using LIDAR, radar and RT-GPS sensors. By analyzing human driving pattern in lane change maneuver, safety index that considers both ego vehicle and surrounding vehicle state by using relative velocity and longitudinal clearance has been designed.

Objectives This study aims to provide directions for future Korean pediatric medicine treatment and researches by analyzing the characteristics of diseases of Korean pediatric outpatients before and after the COVID-19 epidemic. Methods We analyzed the medical records of 10,868 new patients aged 0-18 who visited the Korean pediatrics at Kyung Hee university hospital from January 1, 2019 to June 30, 2021. All patients were divided into 2 groups; patients who visited from January 1, 2019 to December 31, 2019, before the coronavirus epidemic, and patients who visited from January 1, 2020 to June 30, 2021, after the coronavirus epidemic. Within the two groups, the diagnosis distribution was performed for the entire population, by gender and by age group. Diagnoses were classified as allergy, growth, gastrointestinal, respiratory, general body supplementation, neuropsychiatric, skin, urogenital, musculoskeletal, and other systems. Results According to the comparative analysis results of before and after the COVID epidemic, there was a decreasing trend of diagnoses in relates to allergy, respiratory, urogenital, musculoskeletal system. On the other side, there was an increasing trend in gastrointestinal, general body supplementation, growth, neuropsychiatric, skin and other system. Changes in diagnosis based on gender and age group will be described below. Conclusions This study analyzed the characteristics of diseases of Korean pediatric outpatients before and after the COVID-19 epidemic, and suggested the direction of future Korean medicine treatment and researches for pediatrics. Also, this study aimed to propose proper treatments for children by showing the role of Korean pediatric medicine related to growth and development of children during the epidemic. However, this study has limitations such as failure to track the long-term impact of COVID-19. Thus, long term follow-up studies are needed to show the effect of COVID-19 on Korean pediatric medicine.

This paper has two goals: first, I will analyze the current research trend of studying the Nosa School, which is composed of Ki Jeongjin(1798~1879) and his students and then, provide with some tasks we have to solve. The Nosa Studies, which I suggest here, means the one that the scholarship and thought of Ki Jeongjin, one of the six masters and the representatives of neo- Confucianism in late Choson Korea, and all kinds of academic achievements, which had been succeeded and established by his students. Their diverse activities as well as scholarship play crucial roles in both modern Korean Confucianism and Dao Studies in late Choson Korea. Ki's core thought is a conclusion of various issues, which had been raised since Korean Confucianism of Toegye and Yukgok. Their diverse activities kicked into high gear after Ki's death can be understood as one of remarkable cases, which was how to be transformed by encounters with realities in modern Korea. Especially, some controversies and responses to practical issues that linked with their philosophical values of the Nosa Studies in Kiho school in early twentieth century will be a criterion to shed light on the identity of Korean Confucianism today. Thus, I will summarize the content of researches on the Nosa Studies, which begins to appear in the early-mid twentieth century, through an overview of the Nosa Studies, examine research results by dividing part by part, and provide with some prospects and tasks, which are based on what I mention above.

Biodiversity is a key element of ecosystem of which function provides essential product and service in human life. In the course since development projects often causes damages to biodiversity, environmental impact assessment technique must be capable of accurately assessing potential impact from flora and fauna and to entire ecosystem. Korea needs improvement of its assessment technique that is compatible with Korean environmental regulatory standard that is generally stricter than that of most countries. This study attempts to explore both domestic and overseas biodiversity assessment techniques and analyze each stage of environmental impact assessment. The data is collected from numbers of literatures selected by navigating both domestic and overseas literature database with certain keywords. Among the 44 selected papers, overseas publications outnumber those of domestics, and there are more researches on assessment methodology of biodiversity than assessment tool and model. In terms of environmental impact assessment, the number of papers on environmental impact forecast exceeds the numbers of papers on current state of environment and the impact minimizing solution. Therefore, contents and trends of those researches in the different stages of environmental impact assessment discussed in this paper not only suggest potential impact on biodiversity and minimization solutions in detail, but is also a valuable resource particularly for biodiversity relevant environmental assessment technique improvement in Korea. Proposing of a new direction of improvement in biodiversity assessment techniques makes this study significant, and further research for preservation of biodiversity should follow up to provide an improvement scheme for biodiversity assessment techniques in the future.
