Metcalfa pruinosa (Say), native to North America, is spreading rapidly in the Korean Peninsula, causing serious damages on many deciduous forest trees, ornamental trees, and agricultural crops. Before the first report from Korea in 2005, M. pruinosa has not been reported from any other countries in the Eastern Palaearctic, while it has been record in Italy in 1979, and rapidly spreading into many European countries. To trace the invasion route of this species, we analyzed haplotype analysis of the mitochondrial cytochrome c oxidase subunit-I (mtCOI, 577bp), and developed microsatellite markers. In the haplotype analysis, a total of fourteen haplotypes were found from 69 individuals in 18 populations: 12 haplotypes (native region), 4 haplotypes (European region) and 2 haplotypes (Korea). Interestingly, Korean populations were clustered with some European populations. Eight polymorphic microsatellite loci were developed, and population structures were analyzed from 145 individuals in 8 populations. The origin and invasion route of M. pruinosa are under investigation.

산림자원의 효율적인 관리를 위해서는 산림입지환경에 대한 종합 데이터베이스의 기반이 되는 산림입지토양도가 필요하다. 국내에서 그동안 1:25,000 산림입지도가 제작되어 사용되어왔으나 높은 정밀도와 개별 목적에 특화된 산림입지 정보를 갖춘 대축척 산림입지토양도의 필요성이 대두되었다. 이에 따라 2009년부터 2021년까지 1:5,000 축척의 산림입지 토양도 제작사업이 진행되었다. 이와 관련하여 본 논문에서 1:5,000 산림입지토양도 제작 과정과 주요 결과, 활용 방안과 향후 발전 방향을 알아보고자 하였다. 산림입지토양도 제작은 표준매뉴얼에 따라 진행되었으며, 조사 및 분석 결과를 바탕으로 토양형, 토심, 토성별 전국 단위 지도가 작성되었다. 산림입지토양도 자료는 다양한 주제도 제작의 기초가 되며, 산림재해의 방지 및 예측과 환경용량 평가 등에 활용될 수 있다. 그러나 앞으로 산림경영 선진화와 디지털 사회로의 전환에 맞추어 산림입지토양도의 제작 방법을 발전시키고 그 활용방안도 다각화시킬 필요도 있다. 이를 바탕으로 국가 산림기본계획 목표 달성을 위한 다양한 정보 제공, 산림 빅데이터 확보 및 국가 발전 계획에 상응하는 지속가능한 산림경영의 실현 등을 기대할 수 있을 것이다. To improve on the efficient management of forest resources, it is necessary to create a forest soil map, which represents a comprehensive database of forest lands. Although a 1:25,000 scale forest site map has been used in Korea, the need for a large-scale forest soil map with high precision and information on forest lands that is specialized for individual purposes has been identified. Moreover, to keep pace with the advancement in forest management and transition to a digital society, it is essential to develop a method for constructing new forest soil maps that can diversify its use. Therefore, this paper presented a developmental process and used a 1:5,000 scale forest soil map to propose future directions. National maps showing the soil type, depth, and texture were produced based on the survey and analysis of forest soils, followed by the Forest Land Soil Map (1:5,000) Production Standard Manual. Alternatively, forest soil map data were the basis on which various other maps that can be used to prevent and predict forest disasters and evaluate environmental capacities were developed. Accordingly, ways to provide appropriate information to achieve the national forest plan, secure forestry big data, and accomplish sustainable forest management that corresponds to the national development plan are proposed based on results from the current study.

택시 DTG 데이터는 운행위치, 속도 등의 운행 정보를 10초 단위로 수집하는 택시 운행기록 정보로서 현재 서울시에 등록된 7만2천여 대의 택시에서는 연간 1,300억 건의 이동정보가 수집되고 있다. 그러나 최근 택시 DTG 데이터의 대부분은 실시간 소통정보 생성 및 택시 차량 관리용도 외에는 활용되지 않고 있다. 하지만 택시 DTG 데이터는 실제 차량 데이터로서 교통류 분석 등의 활용 가능성이 있다. 본 연구의 목적은 택시 DTG 빅데이터를 통해 산출한 주요도로와 현재 주요 서울시 주요도로 관리 축을 단순 비교 ‧ 분석 하여 기존 주요도로축을 검증 및 확인하고 추가적으로 선정 가능성이 있는 도로를 검출하고자 했다. 분석방법은 DTG 데이터를 가공하여 각 링크별 통과차량대수를 산출하고 통과차량대수가 많은 상위 링크를 산출한다. 결과 값으로부터 주요 도로를 산출하고 기존 서울시 주요 간선도로 관리축과 비교 분석한다. 결과적으로 DTG 빅데이터 분석을 통해 산출된 주요도로가 기존과 상당부분 일치했다. 하지만 통과차량대수는 많은 것으로 관측되나 기존 간선도로 관리축에 포함되지 않은 도로들이 추출되었다. 이는 도산대로, 사평대로 등 통과교통량 상위 200개 추출 링크 기준 5개 도로, 상위 500개 추출 링크 기준 추가 4개 도로이다. 이는 향후 주요도로축 선정 시 고려되어야 할 부분으로 보인다. Taxi DTG (Digital TachoGraph) data is the operation record of personal or corporate taxi cabs belonging to the city government. The DTG data includes many informations such as locations of getting on and off the taxi, travel speed etc. About 72,000taxies registered in the city of Seoul are gathering 130billion traffic information data annually. Currently, most of the DTG data are being discarded except for generating traffic information and vehicle control purposes. However, it is necessary to utilize the Taxi DTG data, actual vehicular traffic data, in traffic operation field such as traffic flow analysis. The purpose of this study is to analyze major arterials in Seoul using taxi DTG big data and to compare with existing major arterials used in the city of Seoul. We extracted traffic volume and speed of each link by processed DTG data and identify major road and compare with the current major arterials used in the city of Seoul. As a result, Although most of the derived roads were consistent with the existing management arterials, there was some road that was not included in existing management targets. This is 5roads extracted by the top 200links and 4 additional roads by top 500links. The road seems to be considered when selecting major roads in the future.

Larval stages of Callipogon relictus (Semenov) (Coleoptera: Cerambycidae), a gigantic longhorn beetle designated as a natural monument of Korea, has never been studied as it is hardly discovered in nature. The DNA barcoding gene, mt-COI, was used to identify a dead larva found in the Gwangneung forest of the Korea National Arboretum. Based on the result, we provide the morphology of the immature stage, with the illustrations of diagnostic characteristics.

Metcalfa pruinosa has been spreading in Korea since 2005, which its first report at Gimhae in Kyeongnam province. It has been harmful to grape and major forest crops by direct sucking and indirect transmitting sooty mold disease causing economical loss. It is necessary to study its tracing route and movement conditions for the further efficient population management and prevention of its re-invasion. A total of 23 haplotype were observed in the analysis of nucleotide polymorphisms on mitochondrial cytochrome c oxidase I from total 124 voucher specimens among five countries. Only two haplotypes were exist in Korea and HAP1 was accorded with its of some European individuals. Moreover, the analysis of FST and AMOVA, the Korean population was relatively nearer with Spanish and Italian population than American populations, suggesting the Korean population might be originated from some European countries. Eight microsatellite loci were developed and characterized to facilitate more delegate population genetic analysis from 468 individual in five countries. The average character of each or overall population was revealed 18 average individual number, six alleles and 0.676 heterozygosity. The genetic distance (FST) was a little bit high among each populations ranged as – 0.010~0.245. In the tracing route analysis, the originating country of Korean population was also shown as migrated from some European countries. The population genetic analysis using genetic markers will be useful to trace the origin of pest and prevent from re-invasion fro efficient pest management.

Lycorma delicatula (White 1845), which has been recently introduced into Korea, is a notorious pest on grapes. This invasive insect has rapidly spread throughout central and southern Korea. To date, we have no behavioral or population genetics information, such as invasion routes and subsequent dispersal rates in Korea, to help understand and control populations of L. delicatula. Here, we have developed 15 novel microsatellite loci for L. delicatula. The isolated loci were polymorphic, with 2 to 19 alleles in 42 individuals from a single population in Cheonan. The analyses revealed that all 42 individuals had different multilocus genotypes with heterozygosity ranging from 0.214 to 0.866. Eleven of the 15 loci did not deviate significantly from Hardy-Weinberg equilibrium. The isolated markers will facilitate population genetic studies of L. delicatula.

Background/Aims: Helicobacter pylori (H. pylori) is a gastrointestinal pathogen known to be associated with cardiovascular disease (CVD). However, most reports about the effect of H. pylori on CVD were investigated in patients with a previous history of CVD and little is known in healthy subjects. We evaluated the association between H. pylori infection and subclinical atherosclerosis using cardiac multidetector computed tomography (MDCT) in healthy subjects without CVD history. Methods: From December 2007 to February 2014, 471 subjects who underwent all of rapid urease test (CLO test), pulse-wave velocity (PWV) and MDCT for health check-up were enrolled. H. pylori infection was defined by CLO test positivity on endoscopic gastric biopsy. Significant coronary artery stenosis was defined as ≥50% stenosis in any major epicardial coronary vessel on MDCT. Results: The CLO-positive subjects had a lower high density lipoprotein-cholesterol (HDL-cholesterol) level than the CLO-negative subjects. Although there was no difference in the mean value of PWV, the incidence of significant coronary stenosis was higher in CLO-positive group (7.9% versus 2.9%, p=0.01). Also, the number of subjects with coronary artery calcium score>0 and Log{(Number of segments with plaque)+1} were slightly higher in CLO-positive group. CLO-positive group was 3-fold more likely to have significant coronary artery stenosis even after adjusting confounding factors (adjusted OR 3.081, 95% confidence interval 1.169-8.119, p=0.02). Conclusions: In a healthy population, current H. pylori infection was associated with significant subclinical coronary artery stenosis. The causal effect of H. pylori on subclinical atherosclerosis in a ‘healthy’ population remains to be investigated further.
