Dangsan forests are traditional village forests which have been established by local residents. They represent unique cultural landscape of Korea with a history of more than several hundred years. It is necessary for a cultural contents to have locality and globality so as to represent Korea. Cultural heritage can retain their value when they are fully sustained their authenticity and management scheme. Although many Dangsan forests have been on the verge of disappearance, the four villages in Sinwon-ri have retained Dangsan forests with Dangsan ritual. In this study, a designation of 'Conservation area of agricultural landscape ecology' including Dangsan forests, Bibo forests, rice paddy field, and stream in Sinwon-ri was suggested. This 'Conservation area of agricultural landscape ecology' can be developed to unique glocal cultural content of rural Korea, and will contribute to enhance the value of the Dangsan forest's, and revitalization of rural villages.

JeongSan(1895-1958) achieves spiritual enlightenment from JeungSan(1871-1909) in 1917. So JeongSans thoughts is origined from JeungSan's Cheonjigongsa. JeungSan's thoughts has a tendency of taoism. JeungSan's taoistic thoughts is chiefly revealed by taoistic human ripening, daily taoistic life. JeungSan maintain his taoistic thoughts through Shinto. JeungSan's Shinto is concerned in Bokhee's Yuk thoughts. Forwardly JeungSan synthesize a period from Cheonhwang. By the way Cheonhwang thoughts has a character of Meuweeihwa. This fact is out a special property of JeungSan's thoughts. That is, JeungSan's taoistic thoughts is related to ancient times Sinto. JeungSan's Shinto thoughts is concerned with JeungSan's taoistic thoughts. JeungSan's Shinto and Meuweeihwa thoughts is together related to JeungSan's Cheonjigongsa. JeungSan's Shinto is progressed by newly religious sacred work named Cheonjigongsa. JeungSan's Shinto is composed of a divine judgment to the universe and human. The Mugeugto is founded through JeungSan's Cheonjigongsa by JeongSan in 1925. The Mugeugto established JeungSan as a religious subject named KucheonEungwonNoiseongBowhoaCheonzonSangje. This treatise disscuss that the Mugeugto taoism is revealed by its turning up time, a religious subject and purpose. The Mugeugto appearence is concerned with Sinwon. JeungSańs Shinto thoughts is composed of a divine judgment that is built up JeungSan as a KucheonSangje. According to it, JeungSan's taoistic thoughts is taoism in the Mugeugto. The purpose of the Mugeugto is a JisangSinseon and a JisangCheonkug. A JisangSinseon thoughts and A JisangCheonkug is realized by JeungSan's Shinto.

As a solution to the wasteful consumption of resources in fashion design, this research aims to develop a process guideline for ZWF Design Methods from an educational perspective. After selecting the Jigsaw Puzzle, Subtraction Cutting, and Layer Methods as representative ZWF Methods, an application experiment was designed to deduct each Method's process, characteristics, needs, and improvement points. Its results were analyzed through action protocol analysis, expert evaluation, and qualitative analysis. Based on the analysis, this research proposed a ZWF guideline and a step-by-step guide suitable to the students' needs. By following the guideline, students can use the chosen ZWF Method to create a planned or an accidental design. In addition, they can practice ZWF effectively step by step in the order of Layer, Jigsaw Puzzle, and Subtraction Cutting. Thus, this research can provide the basis for ZWF education, which can lead to expanded application of ZWF in the future and reduce textile waste.

In this study, growth and burning behavior of 6061 aluminum alloy was studied under constant anodic voltages at various temperatures and magnetic stirring rates in 20% sulfuric acid solution by analysing I-t curves, measuring thickness and hardness of aluminum anodic oxide (AAO) films, observations of surface and cross-sectional images of AAO films. AAO films were grown continuously at lower voltages than 18.5V but burning occurred when a voltage more than 19V was applied in 20% H₂SO₄ solution at 20±0.5℃ and 200 rpm of magnetic stirring. The burning was always related with an extremely large increase of anodic current density with anodizing time, suggesting that high heat generation during anodizing causes deteriorations of AAO films by chemical reaction with acidic solutions. The burning resulted in decreases of film thickness and hardness, surface color brightened and formation of porous defects in the AAO films. The burning voltage was found to decrease with increasing solution temperature and decreasing magnetic stirring rate. The decreased burning voltages seem to be closely related with increased chemical reactions between AAO films and hydrogen ions.

Specialty contractor facilities, which involve a combination of welding and commissioning, face a high risk of serious accidents such as fire, explosion, and suffocation associated with welding work, nitrogen, and argon use. In such facilities, the organizational safety culture has considerable impact on the frequency of accidents. In this study, a safety culture evaluation was conducted on specialty contractors. NOSACQ-50, a standardized survey method on safety culture, was selected as an assessment tool to evaluate the safety culture in specialized construction companies that could not afford to invest heavily in safety. The self-administered questionnaire survey was conducted with 201 workers of four construction companies and the results were analyzed. It was found that in companies with low safety culture, the occurrence of irrationality was 66.0%, while in companies with high safety culture, the occurrence of irrationality was 42.6%. Thus, the difference in the occurrence of irrationality by safety culture was statistically significant. The difference in safety culture level according to the experience of occurrence of irrationality was also significant. It was also found that the higher the belief in safety management authorization, safety responsibilities of managers, worker safety priorities, and safety system effects, the lower the probability of irrationality.

This study aims to explore the direction of high school statistics education in Korea through a comparative analysis between the revised 2022 Korea mathematics curriculum and the IBDP Mathematics: Application & Interpretation Standard Level (IBDP AI SL) Curriculum and textbooks. The study seeks to investigate the Statistics unit of the two curricula, compare chapter structures and content elements of textbooks, and explore exercises on modeling and utilization of technology tools. The results are as follows: First, the IBDP AI SL statistics covered a broader range of topics. Second, exercises in Korean high school textbooks typically inquire about one or two questions in each topic, whereas the IBDP AI SL textbook's exercises present a real-life scenario on all relevant topics through sub-questions. Third, the Korean textbook guides the utilization of technology tools only in exercises presented after completing the entire chapter or where the calculation is complex. Also, there were only a handful of modeling exercises in the Korean textbook in contrast to most of the lessons and exercises were modeling exercises in the IBDP AI SL textbook. If these findings can be integrated into teaching practices in Korea, it will provide a direction for statistics education in Korean high schools.

In recent years, smart clothing had been developed in order to better detect and monitor physical movement of the patient, so that such activities such as location identification and biometric recognition could be done. However, most of the sensing devices of smart clothing were limited to smart sensing sports clothing and the designs did not consider the physical characteristics and the behavior of the wearer. Therefore, this study aimed to create an open protection system by developing a wearable sensing device for health monitoring and location information. For this purpose, this study developed eleven types of wearable sensing design that could be commercially sold and worn by people who needed their biological information to be constantly monitored. The study conducted four tests in order to develop three types of sensing devices for various sensing wears. The purpose of this study was to expand the user rang of smart sensing wears, and provide a foundation for the development of distinctive wearable sensing devices reflecting the user. Furthermore, contribute to the design for the person subject to protection.
