  • 차량의 윤폭과 윤거 정보를 산출하는 답판 센서는 국내 유로 도로의 차종 분류 장치에서 일반적으로 사용 된다. 답판 센서는 차량 정보를 생성하기 위하여, 주행 중인 차랑의 바퀴와 접촉이 필요하며 따라서 이때 발생하는 충격을 견디기 위해 높은 내구성이 요구된다. 최근 한국도로공사가 요금소에서 화물차 고속 차로의 운영을 시작함에 따라, 화물차가 고속 주행할 때 발생하는 설계 기준 이상의 충격으로 인한 답판의 파손과 이에 따른 유지보수 및 관리 비용의 증가가 염려되고 있다. 본 논문에서는 물리적 충격에 대한 내구성을 향상 시킨 무접점 답판 센서를 사용해서, 통과 차량의 차종을 분류하는 알고리즘을 제안하였다. 이는 한국도로공사 6종 분류 방식을 기준으로 하였고, 지방도 1020호선의 창원 요금소를 통과하는 1892대를 대상으로 한 실험에서 99.5%의 분류 정확도를 나타내었고, 무접점 답판을 사용한 차종 분류 장치가 국내 유료 도로에 효과적으로 적용이 가능함을 확인하였다.

  • 국내의 유로 도로에서 사용되는 차종 분류 장치는 차량의 윤폭과 윤거 정보를 산출하는 답판 센서를 사용하는 방식이 일반적이다. 이러한 답판 센서는 주행 중인 차랑의 바퀴가 접촉할 때 발생하는 충격으로 인해 높은 내구성을 요구한다. 최근 한국도로공사는 요금소에서 화물차 고속 차로의 운영을 시작하였고, 화물차가 고속 주행할 때 발생하는 설계 기준 이상의 충격으로 인한 파손과 이에 따른 유지보수 및 관리 비용의 증가가 염려되고 있다. 본 논문에서는 물리적 충격에 대한 내구성을 향상 시킨 무접점 답판 센서를 사용하여, 통과 차량에 대한 최적의 윤폭 / 윤거를 획득하는 알고리즘을 제안하였다. 이는 한국도로공사 6종 분류 기준 중, 축수 분류인 4, 5 종을 제외한 1종/2종/3종 그리고 6종 차량에 대해 현장 실험을 수행하였고, 윤폭 최대 오차 ${\pm}2cm$, 정확도 98% 이상 그리고 윤거 최대 오차 ${\pm}8cm$, 정확도 97% 이상으로 추후 차종 분류 장치 적용에 대한 그 유효성을 입증하였다.

  • This study investigated the characteristics and changes of cotton and silk textile production in Honam district, especially in Gurye, Jella Province from the 1930s to the 1980s. To do this, research method in this study was both literature and fieldwork research and results were as follows. First, in terms of cotton fiber cultivation of Gurye, Chinese Cotton(在來綿) has been substituted for America Cotton(陸地綿) and additionally, Yellow Cotton (黃綿) has been cultivated in the 1930s. Also, in terms of silk fiber cultivation of Gurye, Joseon Silkworm has been substituted for Japanese Silkworm by inflowing the Japanese mulberry tree. Second, in terms of spinning method, cotton spinning has been conducted at every house by an individual tool from the 1930s to the 1950s and has been gradually changed to mechanization by market shop equipped with mechanized cotton gin and cotton whipping tool. However, there have been no changes in silk spinning method from the 1930s to the 1980s. Third, loom type has been changed from the traditional Korean back-strap loom to the treadle loom between the 1930s and the 1940s. Fourth, dyeing was conducted by chemical dyestuff after weaving. The circulation of textile was done through the joint market by Japan in the 1930s~1950s and has changed to the market sales by producers since the 1950s. Fifth, since the 1970s, the outputs of cotton and silk textile of Gurye have been reduced. This was connected with the westernization and the inflow of the synthetic fiber and cloth in cotton and was related to the changes of the nation policy and silk fiber inflow from the china to the Korean farm villages.

  • This study investigated the characteristics of and changes in hemp textile production practices at Gurye in Jeollanam-do in modern times. To do this, in this study, both a literature review and fieldwork research were utilized as research methods. The literature review focused on Gurye's hemp data, and the fieldwork research involved two separate trials. Male and Female residents of Gurye who had experience in the area of hemp production from the 1920s to the 1980s participated in this study. The results were as follows. First, regarding hemp fiber cultivation in Gurye, hemp cultivation continued to the 1970s and there were no changes in hemp cultivation practices during the Japanese colonial-era. Second, there have been very important changes in hemp kilns over time. In the 1950s, there were both single-body kilns and separate-body kilns in Gurye. Later, specifically in the 1950s, a new type of kiln using an iron pot appeared, and the most modern kilns were concrete structures. Third, in Gurye, women cooperatively removed hemp husks immediately after stemming, subsequently bleaching the hemp by soaking it in lye or caustic soda. Over time, there have been changes in ash types and in soaking periods. Fourth, loom types changed from the traditional Korean back-strap loom to the treadle loom in the 1930s- to 1940s. Fifth, since the 1970s, the hemp textile output levels of Gurye have been reduced due to the westernization of clothing styles, the inflow of Chinese hemp fiber and government regulations pertaining to hemp cultivation.

  • This study investigated the characteristics of cotton production of Damyang-gun & Hwasun-gun, Yeongsan River compared with that of Gurye-gun, Seomjingang River in modern times. To do this, research method was both literature and fieldwork research, results were as follows. First, as for cotton fiber cultivation in Damyang-gun & Hwasun-gun, Chinese cotton (在來綿) has been cultivated during Japanese Colonial era unlike Gurye-gun. Especially, Yellow cotton (黃綿) has been cultivated in Hwasungun. Second, as for spinning in Damyang-gun, Hwasun-gun and Gurye-gun, some of cotton spinning process have been gradually changed to mechanization by market shop equipped with mechanized cotton gin and cotton whipping tool since Japanese colonial era. Third, the loom types also, like spinning tools, have been changed from the traditional Korean back-strap loom to the treadle loom in Damyang-gun, Hwasungun and Gurye-gun. Chemical dyeing with chemical dyestuff also has been done since Japanese Colonial era. Fourth, since the 1970s, the outputs of cotton production have been reduced in both Damyang-gun & Hwasun-gun. For Damyang-gun, this has been connected with bamboo craft since the Joseon Dynasty period. So, Damyang-gun has more concentrated on bamboo craft than cotton production. For Hwasun-gun, since Japanese Colonial era, sericulture has been very important. So, Hwasun-gun also has more concentrated on sericulture than cotton production. The main reason to discontinue cotton production in Damyang-gun, Hwasun-gun and Gurye-gun was related to the local choice like economic added value.
