Urban air mobility (UAM) is emerging as a revolutionary transportation solution to urban congestion and environmental issues. Especially, electric vertical take-off and landing (eVTOL) aircraft are expected to enhance urban mobility, reduce traffic congestion, and decrease environmental pollution. However, the successful implementation and operation of UAM systems heavily rely on advanced technological infrastructure, particularly in sensor technology. Among these, 3D light detection and ranging (LiDAR) systems are essential for detecting obstacles and generating pathways in complex urban environments. This paper focuses on the challenges of developing LiDAR-based perception solutions, emphasizing the importance and performance of object detection capabilities using 3D LiDAR. It integrates LiDAR data processing algorithms and object detection methodologies to experimentally validate the effectiveness of perception solutions that contribute to the safe navigation of aircraft. This research significantly enhances the ability of aircraft to recognize and avoid obstacles effectively within urban settings.

middle and upper class families, and examine obstacles to their introduction in Korea. Since a few large-scale facilities for the elderly with dementia have been provided for only low-income families free of charge, the necessity of group homes for middle and upper class families willing to pay for such services has become an issue recently in order to lessen the burden on families, as well as to promote the well-being of the dementia victims themselves. The survey was conducted by questionnaires collected from 577 respondents from middle and upper class families. The results of the survey were as follows: The merits of the group homes were 1)decreasing loneliness of the elderly, 2)providing active and stimulating environments allowing for participation everyday life activities, and 3)lessening the emotional and physical burden on the caring families. Potential obstacles to its introduction in Korea were 1)the difficulty of finding sites to build the group home because of the negative perception of people with disabilities and a NIMBY(Not In My Back Yard) reaction to the construction of it and 2)the economic burden on the caring family. Surprisingly, the guilt factor associated with sending the parents into group homes was not considered as a big obstacle. Referring to results of this study, it is asserted that group homes for the elderly with dementia would be embraced throughout the country if Koreans could have the chance to understand what group homes are.

This paper presents a new method for construction of a static obstacle map. A static obstacle is important since it is utilized to path planning and decision. Several established approaches generate static obstacle map by grid method and counting algorithm. However, these approaches are occasionally ineffective since the density of LiDAR layer is low. Our approach solved this problem by applying probability theory. First, we converted all LiDAR point to Gaussian distribution to considers an uncertainty of LiDAR point. This Gaussian distribution represents likelihood of obstacle. Second, we modeled dynamic transition of a static obstacle map by adopting the Hidden Markov Model. Due to the dynamic characteristics of the vehicle in relation to the conditions of the next stage only, a more accurate map of the obstacles can be obtained using the Hidden Markov Model. Experimental data obtained from test driving demonstrates that our approach is suitable for mapping static obstacles. In addition, this result shows that our algorithm has an advantage in estimating not only static obstacles but also dynamic characteristics of moving target such as driving vehicles.

A decade has passed since the first generation of Genesis was launched in the U.S. with the plaque of Hyundai-Genesis. Genesis Motors was separated from Hyundai Motor in 2015, and has struggled to have the Genesis stand alone in the competitive U.S. luxury sedan market. The present case study aims to find challenges facing the Genesis, which Hyundai has positioned as a luxury sedan competing against conventional luxury brands such as BMW, Mercedes-Benz, and Lexus; evaluate Genesis Motors' strategic response to meet these challenges; and explore an alternative positioning strategy. Specifically, the present case study addresses barriers against the Genesis' market performance, by focusing on the obstacles rooted in the consumer perception as well as the obstacles that stem from the change in the U.S. automobile industry and the nascent network of the Genesis dealership. Genesis Motors' current strategies are evaluated, and an alternative strategy is explored that is largely based on the American consumers' perceptions of the Genesis vis-a-vis conventional luxury brands and outperforming midsize brands.

Objectives: The purpose of this preliminary study was to identify the nurses' perception regarding disclosure of patient safety incidents (DPSI) and to evaluate the effectiveness of education for DPSI. Methods: DPSI education was conducted for nurses majoring in clinical nurse specialist at an university. Before and after the education, the nurses made a questionnaire to evaluate the perception of DPSI. The questionnaires were divided into four categories: first, overall perception of the DPSI; second, recognition evaluation of the DPSI using hypothetical case, third, opinion on legal and nonlegal measures for facilitating the DPSI; and fourth, socio-demographic factors. The Wilcoxon signed rank test was performed on the DPSI questionnaire response to compare the perceptions before and after the education. Results: A total of 10 nurses participated in the education. DPSI education showed the possibility of improving the overall perception, necessity, effect, obstacle, and promotion method of DPSI, although there were also several responses where there was no statistical significance. In particular, DPSI education led to statistically significance change in the perception of obstacles for DPSI. For example, the number of respondents who agreed to the item "DPSI will increase the incidence of medical lawsuits." was 7 before education but decreased to 3 after education (P-value: .025) Furthermore, nurses' perception of DPSI from this study was generally positive regardless of education. Conclusion:In the future, it will be necessary to carry out DPSI education and training and to evaluate its effectiveness for more nurses.

The fact that Pyeongtaek Port is located ideally at the central point of the Yellow Sea's Economic Zone and it is very close to the metropolitan area of South Korea which occupies more than 50 percent of the total trade volume in terms of tonnage is providing a good prospect of development for the Port of Pyeongtaek. This study examines the perception of shippers in Kyonggi-do on the development of Pyeongtaek Port, giving some suggestions to the Pyeongtaek Port Authority. It begins with a description of the port such as current economic status, statistics on the economy, trade and investment regarding the Port of Pyeongtaek. According to a particular questionnaire survey conducted in December 2001, the major obstacles to the utilization of the port are as follows: a shortage of liner shipping routes, lack of container handling facilities including container terminal, crane etc., and port sales promotion activity. Therefore the port should make aggressive efforts to attract container cargoes to and from China by expanding port facilities, implementing effective marketing strategies, introducing a customs-free zone/free trade zone, and strengthening port sales etc.
