노면표시는 도로 이용자에게 안내 및 규제 정보를 제공하는 핵심적인 교통안전 시설이다. 그러나 기존의 표면 도포형 노 면표시는 차량 타이어와의 직접 접촉 및 반복 하중, 환경적 노출로 인해 마모와 박리, 시인성 저하가 비교적 빠르게 발생하 는 한계를 가진다. 이러한 문제는 유지관리 주기를 단축시키고 생애주기 비용 증가로 이어질 수 있다. 본 연구는 이러한 한 계를 개선하기 위하여 제어된 가열 시공 공정을 결합한 열가소성 인레이 방식의 노면표시 시공 시스템을 개발하고 그 적용 가능성을 평가하는 것을 목적으로 한다. 제안된 시스템은 아스팔트 포장 표면 가열, 인레이 홈 형성, 사전 제작된 열가소성 시트의 삽입, 그리고 포장과의 일체화를 위한 2차 가열 공정을 포함한다. 성능 평가는 재료 특성 분석에 국한하지 않고, 시 공성, 교통 하중 하 내구성 및 유지관리 효율성을 중심으로 수행하였다. 실험 결과, 개발된 인레이 시스템은 기존 오버레이 형 노면표시에 비해 접착 안정성이 향상되었으며, 타이어와의 직접 접촉 감소를 통해 표면 열화 저항성이 개선되는 경향을 보였다. 또한 가열 보조 인레이 구조는 시공 일관성과 작업 안전성 측면에서도 긍정적인 효과를 나타냈다. 이러한 결과는 제안된 열가소성 인레이 노면표시 공법이 장수명과 높은 내구성이 요구되는 고부하 도로 환경에서 적용 가능성이 있음을 나 타낸다.

The purpose of this study is to select a fishing gear deposit marking method for the gear deposit system implemented for gillnet. The fishing gear deposit system was implemented in Korea for the first time in the world in January 2024 for fish trap, and it is scheduled to be expanded to gillnets and buoys by 2026. In this study, an AHP (Analytic Hierarchy Process) survey was conducted with 34 experts. The AHP analysis method was used to calculate the weights of each criterion that influence the selection of the deposit marking method, in order to determine the optimal marking method that considers both qualitative and quantitative criteria. Experts prioritized the label-type marking and preferred the weight-based deposit unit for its ease of application and ability to measure multiple gear widths at once. This study quantitatively reflects the opinions of experts on the selection of the gillnet deposit system. Future research should examine the impact of marking method on fishing performance, durability, and institutional improvements.

본 논문에서는 다양한 기상 조건에서 시인성과 내구성을 향상시키도록 설계된 도로 표시용 UV 경화 코팅 시스템 개발을 위해 수행한 연구의 결과를 나타내었다. 제조된 UV 코팅을 사용해 차선 표시의 재귀반사도와 내마모성을 강화하고 포장가속시험(APT), 휠 트래킹 내구성 테스트 등 다양한 테스트를 통해 성능을 평가하였다. 이 결과를 바탕으로 도로 안전을 위한 야간 시인성 및 미끄럼을 개선하 고자 한다.

Although understanding dispersal ecology is important of Haemaphysalis longiconirs (Acari: Ixodidae) to control severe fever with thrombocytopenia syndrome, the small size of H. longicornis makes it challenging to study their behaviors. We examined the potential of fluorescent marking system (FMS) paired with an ultraviolet laser, an effective insect detection method, in tracking of H. longicornis. When we assessed potential effects of FMS on the survivorship and behavioral parameters including horizontal movement, vertical climbing height, and response to CO₂ of all development stages (larva, nymph, and adult) of H. longicornis, it did not induce any adverse effects on the hard ticks. Furthermore, we measured the detectable distance and detection rate of larvae, nymphs and adults to evaluate the detection efficacy of FMS. Using an ultraviolet laser, operators could detect the hard ticks from a distance ranging from 12 m (larva) to 29 m (adult). When the detection rate was measured in a grassland both during day and night, it was higher at night compared to day and increased with the body size. The detection rate was over 90% for all stages of the hard ticks at night, whereas larvae and nymphs showed that of 23% and 34% respectively during the day. However, the detection rate of adults was higher compared to other development stages regardless of time of experiment. Our results indicate that FMS can serve as a promising tool to track the hard ticks by providing reliable detection efficacy with no adverse effects on the marked individuals.

Both a fluorescent marking system (FMS) and a portable harmonic radar system (PHRS) are effective insect tracking methods. Prior to comparing their efficacies, we tested the viability of FMS in detection of an agricultural pest, Riptortus pedestris (Hemiptera: Alydidae); previous studies showed the harmlessness of PHRS on R. pedestris and its detection distance. Fluorescent marking allowed the detection of marked R. pedestris from > 25 m, when illuminated with a laser in the dark, while affecting only the vertical walking distance of the insect. Then, we assessed the efficacy of the FMS and PHRS as well as combining both methods (BOTH) in detection of R. pedestris in a grass field and a bean field during day and night. PHRS and BOTH showed higher detection rates than FMS in all settings, except for in the bean field at night. Also, although BOTH did not enhance total detection time, it facilitated the retrieval of the sample at night compared to only using PHRS.

This study is focused on the elucidation of efficient and correct marking methods by comparing and analyzing marker efficiency depending on the marking job condition such as interval of checking-pattern and marker orientation using woman's Jacket and Slacks. Research Method intended to compare the marking efficiency of Jacket and Slacks, check-less and check- patterned materials with the intervals of 1.5×1.5cm and 5×5cm were selected. First, in the comparison of marking efficiency depending on check-pattern interval, regardless of the direction of marker position, single-item makers and set-item makers, the efficiency of check-less materials was higher than those of check-patterned materials and increasing the intervals decreased marking efficiency and vice versa. Marking efficiency of Slacks was less influenced than marking efficiency of Jacket by check-pattern interval. Second, in the comparison of marking efficiency depending on the direction of marker position, regardless of check-pattern interval and number of maker pieces, the efficiency of nap-up-and-down position was higher than those of nap-one-way position. Third, the marking efficiency of single-item was more effective than one of set-item in all working condition except nap-one-way position in checkless materials.
