The number of big traffic accident cases of pedestrian death appeared to be minor, however compared to death rate in car to car accidents is very high and quite a few of the pedestrian death rates among all traffic accidents are counted to be almost 40%. Previous pedestrian safety studies were mostly aimed at reducing the degree of pedestrian injuries from a vehicle to pedestrian collision, and less at preventing a collision itself. This research was conducted with a method of using road facilities to prevent vehicles from rushing into the sidewalk. This research used one of the collision analyzing programs, called PC-Crash to simulate the vehicle rushing into the sidewalk. Based on the program, it could derive an optimal safe zone location where the pedestrian can wait for the pedestrian light safely. Also, changing road facilities such as pedestrian light pillars or signal controllers can widen 440% compared to the present safe zone. Accordingly, researchers have to consider a method to analyze and apply pedestrian safe zones along with road facilities location when designing a road.

목적 : 본 연구는 농업인들의 근골격계 질환을 예방하며 효율적인 작업환경을 조성할 수 있는 농작업 편이장비 컨설팅 사업을 통하여 농업인들의 컨설팅 만족도 및 필요성에 대해서 알아보고자 한다. 연구방법 : 강원도 W지역 복숭아 농가 중 23가구를 대상으로 6월∼10월 4개월에 걸쳐 컨설팅을 실시하였다. 컨설팅 전 사전 평가로 농작업 동작평가, 기존장비의 만족도 평가, 편이장비 선정 시 고려하는 요소에 대한 평가, 통증 평가를 실시하였으며, 컨설팅 후에 지급된 장비의 만족도 평가, 통증평가, 컨설팅 만족도 평가를 실시하였다. 컨설팅 전.후 통증평가 및 컨설팅 만족도 평가는 대응표본검정 t-test를 실시하였다. 결과 : 기존에 운반작업에서 사용하는 장비로는 대부분이 수동식 손수레를, 제초작업에서는 작업자 신체에 설치하는 동력제 초기를 사용하고 있었으며, 탑재작업은 수작업으로 이루어지고 있었다. 때문에 편이장비 지급 전에는 작업동작에 따른 근골격계 질환의 유해요인이 발견되었고 신체적으로 경험하는 통증도 높은 수준이었으며, 현재 사용 장비에 대한 만족도는 낮은 수준이었다. 편이장비 선정시 가장 중요하게 생각하는 요소로는 ‘수리 및 유지관리’였다. 시연회를 통해 편이장비가 지급된 후, 근골격계 질환 발생의 유해요인인 작업동작의 발생도가 유의미하게 감소하였으며(p<.001), 신체적으로 경험하는 통증 정도 또한 유의미하게 감소하였다(p<.001). 지급된 편이장비에 대한 만족도는 지급전에 비해 향상하였으며, 작업자 만족도와 컨설팅에 대한 만족도는 전체적으로 높은 수준을 보였다. 결론 : 본 연구를 통해 농작업 환경개선 편이장비의 컨설팅에 대한 효과성을 입증하였다. 컨설팅을 통한 편이장비의 인간공학적인 개선은 편이장비에 대한 만족도를 향상시키는데 긍정적인 역할을 할 것으로 기대되며, 추후연구에서는 좀 더 체계화된 컨설팅의 효과에 대한 연구가 필요하다. Objective : Throughout the process of a compact equipment project, the Rural Development Administration is making an effort to improve the agricultural working environment and conditions. The purpose of this study is to identify the characteristics of agricultural work and investigate the need for a consulting project on improving the working conditions and worker satisfaction. Methods : Twenty-three peach farmers living in a rural town, W, participated in this study. The project proceeded in the following sequence: First, we investigated the risk factors for musculoskeletal disease by evaluating the subjects’ working postures, satisfaction with preexisting equipment, factors of consideration when selecting compact equipment, and degree of pain in the musculoskeletal region. After a consultation process, we evaluated the working posture and degree of pain. A survey of worker satisfaction with the equipment and a consulting service were conducted. Results : Before being provided compact equipment, the workers used handcarts for most of their carrying work, wearable equipment while weeding, an no equipment during loading work. Because of preexisting working conditions, they had many risk factors in terms of musculoskeletal disease. Their degree of pain was rather high, and satisfaction with their preexisting working equipment was rather low. The ‘Repair and Maintenance Service’ factor was chosen to be the most important factor when selecting compact equipment. After using the new equipment, their risk factors in terms of musculoskeletal disease and degree of pain decreased significantly(p<.001). Also, their satisfaction with the equipment and consulting service was rather high. Conclusion : This study suggests that the compact equipment project has had a positive effect on improving agricultural work-related problems and satisfaction with equipment and the consulting process. We expect that this kind of consulting service can increase worker satisfaction regarding equipment and working conditions. In the future, more research on the effects of a systematic consulting project will be needed.

In this study, the Euro NCAP-based AEB system evaluation simulation was conducted by applying the calculated corrected TTC by road condition estimation of scenarios (CPFA, CPNC, CPLA) of the V2P situation scenario using PC-Crash, a program used for traffic accident analysis. The scenario was evaluated in consideration of the two road conditions. the low-speed conditions among every scenarios avoided collision, but in the medium and high-speed conditions has been collided with pedestrian. It was confirmed that the time point at recognizing pedestrian was lower than set TTC at which AEB system was operated, even though the AEB was operated immediately, a collision occurred due to insufficient braking distance. As in this study, if studies such as V2V, V2P, and V2B considering road friction are actively conducted, it is expected to be useful data for automobile accident prevention and accident analysis.

Ex-situ 화학적 산화처리 적용을 위하여 다양하게 활성화(heat, Fe²⁺, UV)된 persulfate를 이용한 TCE 분해에 대한 연구

김한솔,도시현,박기만,조영훈,공성호,Kim, Han-Sol,Do, Si-Hyun,Park, Ki-Man,Jo, Young-Hoon,Kong, Sung-Ho 한국지하수토양환경학회 2012 지하수토양환경 Vol.17 No.6

Rreactivity of persulfate (PS) for oxidation of TCE under various conditions such as heat, $Fe^{2+}$, and UV was investigated. It was found that degradation rate of TCE increased with increasing temperature from 15 to $35^{\circ}C$. At pH 7.0, the rate constants (k) at 15, 25, 30, and $35^{\circ}C$ were 0.07, 0.30, 0.74, and $1.30h^{-1}$, respectively. For activation by $Fe^{2+}$, removal efficiency of TCE increased with increasing $Fe^{2+}$ concentration from 1.9 mM to 11 mM. The maximum removal efficiency of TCE was approximately 85% when pH of the solution dropped from 7.0 to 2.5. Degradation of TCE by UV-activated PS was the most effective, showing that the degradation rate of TCE increased with inreasing PS dosage; the rate constants (k) at 0.5, 2.5, and 10 mM were 34.2, 40.5, and $55.9h^{-1}$, respectively. Our results suggest that PS activation by UV/PS process could be the most effective in activation processes tested for TCE degradation. For oxidation process by PS, however, pH should be observed and adjusted to neutral conditions (i.e., 5.8-8.5) if necessary.

Currently, fuel efficiency becomes one of critical issues for automotive industries as concerns about environmental and energy problems grow. In an automatic transmission of an automobile, a drag torque due to a viscous drag of a fluid between friction and clutch plates is one of factors that degrade fuel economy. In this work, the drag torque characteristics of a wet clutch was experimentally investigated with respect to rotational speed, temperature of automatic transmission fluid (ATF), and gap between friction and clutch plates. The experimental results showed that drag torque increases to a certain level, and then decrease to the steady state value with increasing rotational speed. This behavior may be associated with two-phase flow of air and ATF at gap between friction and clutch plates. Also, it was found that the maximum drag torque value decreased as ATF viscosity decreases with increasing temperature. However, it was shown that the point at which the maximum drag torque occurs was not significantly affected by the ATF temperature. In addition, maximum drag torque was found to decrease as the gap between friction and clutch plates increased from 0.1 mm to 0.2 mm. Furthermore, it was observed that the generation of maximum drag torque was delayed as the gap increased. The outcomes of this work are expected to be helpful to gain a better understanding of drag torque characteristic of a wet clutch, and may therefore be useful in the design of wet clutch systems with improved performance.

디지털방사선영상에서 산란선의 영상특성 평가

김한솔,김창수,Kim, Hansol,Kim, Changsoo 한국방사선학회 2022 한국방사선학회 논문지 Vol.16 No.4

본 연구에서는 디지털방사선영상 시스템에 사용되는 평판형 검출기(flat-panel detector, FPD)를 이용하여 조직 등가 물질인 폴리메틸메타아크릴레이트(Polymethyl Methacrylate, PMMA)의 두께 변화에 따라 발생되는 산란선이 영상품질의 영향으로서 해상력 평가의 변조전달함수(modulation-transfer function, MTF)와 잡음력 스펙트럼(noise-power spectrum, NPS)으로 정량적인 영상 평가를 위한 연구를 수행하였다. 해상력-차트 팬텀 영상으로 PMMA 두께가 증가할수록 산란선의 영향이 커져 변조특성이 저하 되는 것을 알 수 있고 영상이 밝다. 결과는 영상의 잡음이 많아진다는 것을 알 수 있는데 공간주파수 별로 확인하기 위해 푸리에 변환으로 잡음력 스펙트럼 영상을 얻었다. 그러므로 영상에서 피사체로서 PMMA 두께 증가에 따라 산란선의 변화를 MTF로 평가하여 해상도 특성변화와 2차원 잡음력 스펙트럼을 1차원 값으로 나타낸 결과를 통해 PMMA 두께와 잡음은 비례하는 것을 확인할 수 있다. Flat-panel detector (FPD) used in digital radiographic imaging systems was used to perform a quantitative power spectrum evaluation as a result of the thickness change of polymethyl methacrylate (PMMA), a tissue equivalent. As the PMMA thickness increases with the resolution-chart phantom image, the effect of the scattering line increases, indicating that the modulation characteristics decrease, and the image is bright. The results show that the noise of the image increases, and noise-power spectral images are obtained by Fourier transform to confirm by spatial frequency. Thus, it can be verified that the PMMA thickness and noise are proportional through the result of evaluating the change of resolution characteristics and representing the 2D noise-power spectrum as one-dimensional values by evaluating the change of scattering line with MTF as the PMMA thickness increases in the image.

This paper presents an evaluation system to determine the completeness of a space map obtained by a visual SLAM(Simultaneous Localization And Mapping) algorithm. The proposed system consists of three parts. First, the proposed system detects the occurrence of loop closing to confirm that users acquired the information from all directions. Thereafter, the acquired map is divided with regular intervals and is verified whether each area has enough map points to successfully estimate users’ position. Finally, to check the effectiveness of each map point, the system checks whether the map points are identifiable even at the location where there is a large distance difference from the acquisition position. Experimental results show that space maps whose completeness is proven by the proposed system has higher stability and accuracy in terms of position estimation than other maps that are not proven.
