      • 고속도로 비탈면 녹화 시험시공지에 대한 암질별 녹화효과 분석

        이제만,김경훈,전기성,임상준 한국산림공학회 2021 산림공학기술 Vol.19 No.2,3

        본 연구는 고속도로 암반 비탈면을 대상으로 녹화공법으로의 적용성을 평가하기 위해 고속도로 건 설 현장 암반 비탈면에 녹화공법을 시험시공하여 그 효과를 조사·분석하였다. 이를 위해 한국도로 공사 수도권건설사업단 화도양평 제3공구에 위치한 암반 비탈면 1,000 m2 를 대상으로 토질에 따 라 암반 비탈면 식생기반재뿜어붙이기의 3개 공종으로 적용공법을 달리하여 시험시공을 실시하였 다. 이후 시간의 경과에 따른 출현식물, 식물생육 상태, 식생기반재 안정성으로 조사항목을 구분하 여 모니터링을 국토해양부 녹화지침에 근거하여 실시하였다. 그 결과 출현식물의 경우 목본성립본 수는 1.0~1.7본/m2으로 비탈면 복원목표 기준에 비해 약 33.3~55.6%로 나타났으며 출현종 수는 조사구(1 m2)당 9~10종으로 비탈면 복원목표 기준 약 129~143%의 달성도에 해당하는 것으로 조사되었다. 식물생육 상태의 경우 식생 피복률과 식물생육량, 그리고 병충해를 조사하여 평가하였 는데 1차 모니터링에 비해 2차 모니터링에는 상당 부분 쇠퇴가 나타났다. 이는 여름철에 일반적으 로 발생하는 하고현상에 의한 것으로, 3차 모니터링에는 개선됨을 확인하였다. 식생기반재 안정성 은 시공지에 발생한 탈락 및 붕괴, 그리고 식생기반재의 물리화학적 특성을 조사하였다. 시공지에 탈락이나 붕괴현상은 나타나지 않았으며 토양 산도는 6.7~7.0의 범위로 나타났고, 토양수분과 토양 경도는 각각 13.7~58.3%와 11.0~15.3 mm로 큰 편차를 나타냈는데 이는 조사 시점에 발생한 강 우로 인한 변동성으로 확인되었다. 이 연구는 추후 식생기반재뿜어붙이기가 적용된 암반 비탈면에 대한 녹화 기초자료로서 활용될 수 있을 것이다. In this study, to evaluate the applicability of the greening technique to the rocky slope of the expressway, Pilot implementation and monitoring were conducted on the rocky slope of the expressway construction site, and the greening effect was investigated and analyzed. To this end, a pilot implementation with soil-media hydroseeding was carried out to the 1,000 m2 rocky slope located in Hwado-Yangpyeong Expressway Section 3, constructed by Korea Expressway Corporation. Subsequently, monitoring was carried out by investigating appeared species, plant growth conditions, and soil-media stability over time. As a result, in the case of emerging plants, the number of woody trees was 1.0~1.7 per 1 m2, and the number of investigated species was 9~10 per survey area(m2). In the case of plant growth condition, vegetation coverage, plant growth rate, and pests were investigated and evaluated. Compared to the primary monitoring, the secondary monitoring showed a significant decline. This is due to the summer depression that generally occurs in summer season, and it was improved for the tertiary monitoring. For the stability of the soil-media, the drop-off and collapse occurred in the research site, and the physicochemical characteristics of the vegetation substrate were investigated. There was no drop-off or collapse at the research site. Soil acidity(pH) was in the range of 6.7 to 7.0, and the soil moisture and hardness were 13.7 to 58.3% and 1.0 to 15.3 mm, respectively. This is due to the variability caused by rainfall during the survey. This study can be utilized as basic greening data for the rocky slope to which the soil-media hydroseeding has been applied.

        Palm prints have been used for personal identification because they are unique to each individual. Palm prints have also been used for diagnosing genetic disorders and for revealing physical anthropological characteristics, due to their specific appearance characteristic of genetic factors and nationality. Therefore, several analytical methods of palm prints have been developed and applied for the purpose described. However, in the previous reports, the analytical methods of palm prints and the numbers of subjects were insufficient to find Standard values for Korean palm prints. In this study, in order to determine the Standard value for Korean palm prints, we examined palm prints of 3216 Korean adults (2095 males and 1121 females), analyzed the data according to sex and side of hand, and compared with those of foreigners. The results are s follows: 1) The incidence of 7, 9, and 11 of D was 41.8%, 33.5%, and 20.4%, respectively. Comparing the incidences 017, 9, and 11 of D in Koreans with those of foreigners, the Korean belong to the Asians including the Japanese, the Chinese, and the Philippine, however, the Korean was doser to the Blacks and distant from the Whites than the other Asians. 2) The palm prints were classified into the open type in which B terminates at the ulnar border of hand, and the dosed type in which B does not. Open type, 7-5-5 (male 37.6%, female 39.5%) and 9-7-5 (male 23.9%, female 25.5%), was more frequent in female than in male, while dosed type, 11-9-7 (male 9.8%, female 9.1%), was more frequent in male than in female. Also, open type, 7-5-5 (right 28.9%, left 47.6%), was more frequent in left hand than in right hand, while dosed type, 11-9-7 (right 17.1%, left 2.1%), was more frequent in right hand than in left hand. Consequently, open type was more frequent in the weak hand, whereas dosed type was more frequent in strong hand. 3) Because a-b (39.2) and c-d (35.0) were more numerous than b-c (27.8), distance between a and b and between c and d were longer than that between c and d. The long distance of a, b and c, d could be resulted by wide moving range of second finger and fifth finger, respectively. Also, there was a tendency that the palmar ridge counts of right hand was more numerous than those of left hand, which could be resulted by wide moving range of right fingers in the right-handed persons who were more frequent than the left-handed persons. 4) O, in which there was no triradius, and X, in which dermal ridge from a triradius was blocked and terminated at the other dermal ridge, were frequent in C (O 7.8%, × 7.2%) than in D (O 0.1%, × 0.1%) or in B (O 0.4%, X 1.2%). The frequency of 0 and X in C was thought to be related with the location of ein the narrow space between d and b. The narrow space between d and b was known because c-d and b-c was less numerous than a-b. 5) The distances between adjacent triradii were longer in male than in female, however, the palmar ridge counts for a-b, b-c, and c-d were less numerous in male than in female. Consequently, dermal ridges were thought to be thicker in male than in female. The Standard values of Korean palm prints obtained from this study are expected to be used for both diagnosing genetic disorders and for revealing physical anthropological characteristics in Korea. Further studies to clarify the relationship between the palm prints and the power of hand as well as the moving range of fingers are in need.

        Background: We monitored the prevalence of antimicrobial resistance and the pattern of multiple drug resistance in Escherichia coli isolated from healthy people in the community. Methods: We performed antimicrobial susceptibility testing on 491 isolates of E. coli from 692 healthy people in Incheon from February to July in 2006. The results were interpreted according to the CLSI guidelines. Results: The highest rate of resistance was observed against tetracycline (46.6%), ampicillin (41.1%), ticarcillin (37.9%), streptomycin (31.0%), and nalidixic acid (23.6%). Twenty six percent of isolates were observed to be resistant to five or more of the antimicrobials tested. Conclusion: In order to maintain a low level of antimicrobial use and resistance, the surveillance of antimicrobial resistance in the community would be very important, as it provides epidemical data to set up and control antibiotic guidelines and serves as an early warning for resistance in pathogenic bacteria.

        This study investigated and analyzed the effects of vegetation on the roadside slopes at the expressway construction sites in order to evaluate the vegetation recovery regarding soil type and revegetation technique. We selected two study sites with an area of 1,000 m2 located in the construction sites of the Korea Expressway Corporation, named Hwado-Yangpyeong Expressway Section 3 and Saemangeum-Jeonju Expressway Section 7. The revegetation was monitored in three plot groups (earth, soft rock, and hard rock slopes), and scored based on the guideline of the Ministry of Land, Transport and Maritime Affairs. The revegatation was generally lower in the Hwado- Yangpyeong site than that of the Saemangeum-Jeonju site. The field monitoring indicated that the revegetation varied with slope aspect and environmental characteristics between plots. the Saemangeum-Jeonju site showed a high overall evaluation score, but there was a slight difference in the score for each plot. This seems to be due to the differences in geographical conditions, construction methods, and site environment between two sites. This study can provide basic information to understand the short-term effects of revegetation techniques in the roadside slopes.
