In this paper, we propose a lossless compression scheme for cloud point data of the target construction by using doubleness and decreasing useless information of cloud point data. We use Hough transform to find the horizontal angle between construction and terrestrial LIDAR. This angle is used for the rotation of the cloud point data. The cloud point data can be parallel to x-axis, then y-axis doubleness is increased. Therefore, the cloud point data can be more compressed. In addition, we apply two methods to decrease the number of cloud point data for useless information of them. One is decimation of the cloud point data, the other is to extract the range of y-coordinates of target construction, and then extract the cloud point data existing in the range only. The experimental result shows the performance of proposed scheme. To compress the data, we use only the position information without additional information. Therefore, this scheme can increase processing speed of the compression algorithm.

What has been rapidly changed and developed is not only technology, but also language and culture, of which the diverse consensus has been speedily formed between generations and spread throughout all the social grades. Therefore, Neologisms need to be understood as part of the cultural history that is created at each period. We cannot keep neologisms, initially formed among the youths, from spreading all over the generations, not just for their enjoyment, convenience, and familiarity, but more for the fact that they are impossible to be replaced in use. Another reason is that a community is created according to language. The youths would like to make distance from the existing community by building an invisible wall of new language. This paper is intended to deal with neologisms, centered on visual pun. The characteristics of the Neologisms are the result of the tendency of the younger generation to avoid interference and to enjoy adding ingenuity to the existing order.That is why in all ages Neologisms are created, and although they differ in form, the principles of new word generation are old. We will also consider the historical characteristics of neologism in this paper.

The high wind wave alert has a great impact on ships and maritime service workers navigating in the vicinity of Korea. This study aims to evaluate the appropriateness of the high wind wave alert by comparing and analyzing the observation data of major marine meteorological buoys with the high wind wave alerts in the coastal sea and offshore of the West Sea, South Sea, and the East Sea announced by the Korea Meteorological Administration for the past 11 years(2010-2020). As a result of comparing the daily, monthly, and annual statistics of the high wind wave alert and marine meteorological buoy observation data for each sea area by annual, monthly, and seasonal average, the accuracy of high wind wave alerts was very low across the entire sea area. In particular, it was analyzed that the accuracy in the coastal sea of the South Sea and Jejudo was the lowest in winter. It was confirmed that the accuracy of marine weather forecasts and alerts needs to be improved when considering the effects of the high wind wave alerts on fishing vessels, passenger ships operations and tourism, and marine leisure activities.

This study explored the link between reproductive health knowledge, attitudes, and self-efficacy in young women from Uganda's Luwero district. A survey was conducted on 82 women in the Luwero region from May to July 2016, and the predictive power of knowledge and attitudes toward self-efficacy was evaluated through multiple linear regression analysis. Results showed positive correlations among these factors, with knowledge and attitude predicting self-efficacy. Specifically, understanding healthy puberty habits and valuing women's roles positively influenced self-efficacy for healthy behaviors. These findings emphasize the need to target these aspects in reproductive health education programs, crucial for addressing adolescent pregnancy and related issues in Uganda's rural areas.

In religious symbology, an emblem is a symbolic mark, which differentiates a religion from other groups. In addition, it holds a symbolic or conceptual character that enables viewers to recognize a certain religion. Daesoon Jinrihoe, a representative order among Korean religious traditions, also has a symbolic mark; however, it has not been designated with an official name as symbol despite its usage dating back to May 11, 1978. At the time, that mark has served as an emblem. Afterwards, the emblem was printed and has been officially used as a flag (unofficially known as the Dao Flag, the Fellowship Flag, etc.) since October 20th of that same year. The emblem of Daesoon Jinrihoe which is not only printed in the flag but has been utilized as a symbolic mark representing the order. Nevertheless, it is hard to find research related to this symbol. Consequently, this study aims to apprehend the existing materials about the flag's emblem and its meaning, as well as attempt to interpret its various implications. Indeed, this work will suggest another point of view about the emblem given that it embraces ambiguity. This research suggests that the emblem symbolically depicts the Daesoon (Great Itineration), Samwon (三圓, Three Circles), Sadae (四大, Four Dae), and the Center, and that, all together, this can imply more profound meanings than were expressed in previously posited explanations. As such, this study draws further significance from Daesoon Thought and find: first, the circle in the center of the emblem signifies the pivot of Daesoon; not just the earthly circle (地圓) or the human circle (人圓). This opens up the possibility that the circle symbolizes Mugeuk (Limitlessness) and Taegeuk (Great Ultimate), which include the pivot of Heaven, Earth, and Humanity. Secondly, the symbol of soil (土) in the center is separated from the human circle and reveals the symbol of harmony and creation as the rod shape of Four Dae. Thirdly, the protuberances in the circle point to specific directions and this allows for additional layers of meaning.

This study analyzed the service philosophy of Eastern mainstream thought in order to establish a service philosophy. Following a prior study the "study of the service philosophy of major korean ideology", we explored the service philosophy of the Eastern mainstream ideology of China and India and it's coherence. The existing basic structure and operational model of service philosophy were presented in depth and the service philosophy of Oriental mainstream thought was derived. The philosophy of service can be presented as an idea of the structure of the service and as an idea of the operation of the service. It suggested compatibility of the service philosophy of Asian mainstream ideas, and analyzed them mainly in China and India. Indian ideas revolved around the ancient philosophy of Veda, Upanishads philosophy, and representative Buddhist philosophy. It also showed that a major trend of mainstream ideas in China and India was found to be compatible with the service philosophy. Follow-up studies are needed to further refine the structure of service philosophy and develop the principles of operation into larger ideas in the future, and a study of conformity of service philosophy in representative Western ideas, focusing on Greek, Roman, and German philosophy, is also required. Ultimately, it is necessary to establish a service philosophy as an ideological base that drives future economic and social development.

In order to increase timber self-sufficiency, Korea's 6th Basic Forest Plan aims to increase the density of forest roads to 12.8 m ha^-1 by 2037. However, due to rapid re-forestation, current management infrastructure is insufficient, with just 4.8 m ha^-1 of forest roads in 2017. This is partly due to time and cost limitations on the process of forest road feasibility evaluation, which considers factors such as topography and forest conditions. To solve this problem, we propose an eco-friendly and efficient forest road network planning method using a geographic information system (GIS), which can evaluate a potential road site remotely based on spatial information. To facilitate such planning, this study identifies forest road construction priorities that can be evaluated using spatial information, such as topography, forest type and forest disasters. A method of predicting the optimal route to connect a forest road with existing roads is also derived. Overlapping analysis was performed using GIS-MCE (which combines GIS with multi-criteria evaluation), targeting the areas of Cheongsong-gun and Buk-gu, Pohang-si, which have a low forest-road density. Each factor affecting the suitability of a proposed new forest road site was assigned a cost, creating a cost surface that facilitates prioritization for each forest type. The forest path's optimal route was then derived using least-cost path analysis. The results of this process were 30 forestry site recommendations in Cheongsong-gun and one in Buk-gu, Pohang-si; this would increase forest road density for the managed forest sites in Cheongsong-gun from 1.58 m ha^-1 to 2.55 m ha^-1. This evaluation method can contribute to the policy of increasing timber self-sufficiency by providing clear guidelines for selecting forest road construction sites and predicting optimal connections to the existing road network.
