Purpose: This study aims to examine how college students perceive the usage environment of electric kickboards, recognize safety issues, and seek ways to improve them. Methods: A descriptive survey was conducted on 180 college students from November 1 to November 8, 2023, to analyze the environment and risks associated with using electric kickboards. Results: College students perceived electric kickboards as extremely dangerous. However, they did not receive safety education and 76.4% of the subjects did not wear safety helmets when driving electric kickboards. Women suggested lowering the speed of electric kickboards, including in certain sections, and emphasized that the more accidents they experienced, the more necessary it was to improve regulations. Conclusion: This study comprehensively illustrates the perception of risk and speed improvement among electric kickboard users, and emphasizes the need to prepare detailed guidelines for implementing and operating safety education.

본 연구는 호남고속철도 계획에서 검토되어야 할 쟁점들을 다룬다. 이 연구에서는 프랑스의 TGV 노선망을 검토하고, 호남고속철도 기점 역으로서 청주역과 천안역을 비교·평가하며, 그밖에 계획의 주요 쟁점을 정리하는 데 중점을 두고 있다. 연구결과를 요약하면 다음과 같다. 우선 프랑스의 TGV 경험과 IMF 체제라는 상황에 비추어 호남고속철도 계획은 경부고속철도와 기존 철도의 활용이라는 관점에서 출발해야 한다. 둘째, 노선대안을 비교·분석한 결과 대안 I (청주기점역)이 대안 II(천안기점역)에 비해 모든 평가항목에서 바람직한 것으로 판단된다. 셋째, 노선대안 외의 쟁점으로는 계획과정의 투명성 확보, 21세기 고속철도의 위상정립, 기존철도의 개량계획과의 조화, 수송의 효율성과 지역개발 간의 갈등 등이 있으며, 이에 대한 지속적인 논의가 필요하다.

Alcoholic liver disease (ALD) is a significant risk factor in the global disease burden. The stem bark of the Betulaceae plant Alnus japonica, which is indigenous to Korea, has been used as a popular folk medicine for hepatitis and cancer. However, the preventive effect of Alnus japonica leaf extracts on alcohol-related liver damage has not been investigated. The objective of this study was to investigate the hepatoprotective effects of the extracts of Alnus japonica leaf (AJL) against ethanol-induced liver damage in HepG2/2E1 cells. Treatment with AJL significantly prevented ethanol-induced cytotoxicity in HepG2/2E1 cells by reducing the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). This protective effect was likely associated with antioxidant potential of AJL, as evidenced by the attenuation of reactive oxygen species (ROS) and malondialdehyde (MDA) production and restoration of the depleted glutathione (GSH) levels in ethanol-induced HepG2/2E1 cells. Our findings suggest that FCC might be considered as a useful agent in the prevention of liver damage induced by oxidative stress by increasing the antioxidant defense mechanism.

This experiment was conducted to investigate the effect of sulfur containing fertilizers on growth, yield and nutritive quality of soybean as affected by lime application at reclaimed soil. Lime application for neutralization requirements showed the effect of increased grain yield about 32% compared to the non application at newly opened land of red and yellow soil. In case of lime application, the sulfur containing fertilizers combined with super phosphate, ammonium sulfate, and gypsum increased the grain yield by 31%, 11%, and 3%, respectively. When lime was not applied, magnesium carbonate application increased the yield by 47%, super phosphate by 22%, and gypsum by 15%. The protein content of grain was higher at lime application than those of non lime application and was increased by the application of sulfur containing fertilizer. But lipid content was not affected by lime or sulfur application. From the above results obtained it was concluded that sulfur fertilizer effect under lime application was significant when combined with super phosphate or ammonium sulfate application. Magnesium carbonate or super phosphate application was the best combination with sulfur-containing fertilizer.

The seasonal variation and frequency of precipitation phenomenon of the Honam region in summer show strong local weather phenomena because of its topographical and geographical factors in southwestern area of Korea. The propose of this treatise is to induce variation patterns over a period 10 days of summer precipitation(that is one of the important elements of the precipitation characteristics), clarify the variations of their space scales, and study the subdivision of precipitation regions in Honam according to the combinations of precipitation amounts and variation pattern over a period of a 10 days of summer precipitation, using the mean values during the years 1994$\sim$2003 at 79 stations(the surface synoptic stations 16 AWS 63) of Honam region. The classified precipitation of a period of 10 days summer precipitation, and the principal component vector and the amplitude coefficient by the principal component analysis were used for this study. The characteristics of variation pattern over a period of 10 days of summer precipitation can be chiefly divided into four categories and the accumulated contributory rate of these is 78.0%. And the change patterns of summer precipitation during a period of 10 days in honam region are classified into 11 types from A to K And regional divisions of summer precipitation in Honam region can be classified into 18 types.

This study is to find out the legitimacy and features of Honam Choreography via Lee Mae-bang and Han Jin-ok, two of the masters, and to seek better and more creative ways to pass it down in view of regional particularities. The study looks into the traditional choreography's multi-conceptuality that is derived from various forms of art and lends it its identity with the original notion rooted in Buddhist dancing. Despite the local cultural traits of the Honam area, the fact that Lee Mae-bang is more feminine and Han Jin-ok more masculine shows the two's worlds of dancing have been created from different perspectives, though they are quite common in their roots and locales. The particularities of passing down traditional choreography are given a thought in this study with the distinction and identity taken into account. Also, it will give an opportunity to discuss the importance of localism as aesthetic consciousness and communica tion channel. In any case, there is no doubt that local difference and communica tion make a very important source of culture when we look into the originality of the choreography.

In this paper, the algorithm was developed to recognize hand golve gesture and implemented a system to remotely control the robot. The system consists of a camera and a controller that controls robot motion by hand position gesture. The camera recognizes the specific color of the glove and outputs the recognized range and position by including the color area of the glove. We recognize the velocity vector of robot motion and control the robot by the output data of the position and the detected rectangle. Through the several experiments, it was confirmed that the robot motion control was successfully performed.
