본 연구는 산지초지에서 애기수영의 분포를 신속하고 정밀하게 파악하기 위안 무인기 촬영 항공영상의 이용가능성을 실험하였다. 항공영상은 일반 디지털카메라로 촬영한 RGB 영상과 자체 제작한 NIR 카메라로 촬영한 NIR 영상을 이용하여 각각 Red, Green, Blue 벤드와 NIR 밴드를 이용하였고, 밴드조합에 따른 애기수영의 건물비율과의 상관관계를 조사하였다. 다중선형회귀분석 결과 NIR+R+G+B 밴드의 조합이 가장 높은 상관관계($R^2$, 0.96)를 보였으며, R+G+B 밴드의 조합이 다음으로 높은 상관관계를 보였고 ($R^2$, 0.91) NIR+R 밴드($R^2$, 0.45)와 NIR+G 밴드 ($R^2$, 0.27)는 상대적으로 낮은 상관관계를 보여 NIR+R+G+B 밴드조합이 애기수영 분포 파악을 위하여 가장 적합한 것을 확인하였다. R+G+B 밴드 조합의 경우 NIR+R+G+B 밴드의 조합과 비교하여 예측정확도가 큰 차이가 나지 않았으며 근적외선 카메라 없이 일반 디지털 카메라로 영상정보의 획득이 가능하기 때문에 현장적용성 면에서 장점을 가질 것으로 판단된다. Red sorrel (Rumex acetosella L.), as one of exotic weeds in Korea, was dominated in grassland and reduced the quality of forage. Improving current pasture productivity by precision management requires practical tools to collect site-specific pasture weed data. Recent development in unmanned aerial vehicle (UAV) technology has offered cost effective and real time applications for site-specific data collection. To map red sorrel on a hill pasture, we tested the potential use of an UAV system with digital cameras (visible and near-infrared (NIR) camera). Field measurements were conducted on grazing hill pasture at Hanwoo Improvement Office, Seosan City, Chungcheongnam-do Province, Korea on May 17, 2014. Plant samples were obtained at 20 sites. An UAV system was used to obtain aerial photos from a height of approximately 50 m (approximately 30 cm spatial resolution). Normalized digital number values of Red, Green, Blue, and NIR channels were extracted from aerial photos. Multiple linear regression analysis results showed that the correlation coefficient between Rumex content and 4 bands of UAV image was 0.96 with root mean square error of 9.3. Therefore, UAV monitoring system can be a quick and cost effective tool to obtain spatial distribution of red sorrel data for precision management of hilly grazing pasture.

The purpose of this study was to investigate the status and views on the dental team composition and works, the experience of a dental manpower shortage and opinions on the solution. The subjects were 313 dentists and dental hygienists. The mobile questionnaires were conducted on the status of dental team composition and works, the experience of a dental manpower shortage and opinions on the solution. There was no big difference between the current dental team composition and ideal composition ratio, and dentists answered that it would be more ideal to reduce dental hygiene and increase nurse assistant when the working dentist was 3~5. 85.6% of the dentists and 56.4% of the dental hygienists had difficulty in employing the dental auxiliary personnel. The difficulty level was 8 out of 10 points among dentists and 5.7 points among dental hygienists. 91.1% of the dentists and 95.5% of the dental hygienists agreed on the necessity of expanding the dental hygienist's work. The dental works were temporary crown making and setting, surgical operation assistance, and overall dental assistance. Based on the results of this study, it is necessary to continuously make efforts to communicate with the dental personnel in Korea to solve a lot of problems such as the job assignment, the dental personnel policy and system, and the work environment.

This study focused on comparing the following acoustic changes according to age and sex in adulthood: Fo, Jitter, Shimmer, and NHR. One hundred twenty Korean adults were divided into three age groups (20's, 50's, and 70's) and two sex groups (male and female). The subjects of this study performed three tasks: (1) sustained three vowels; (2) read on paragraph of 'Taking a Walk' (3) explained a picture. The data was analyzed using the MDVP of Multi-Speech. In the parameter of Fo, sex and age were influential factors. In the parameters of Jitter, Shimmer and NHR, the effect of sex and age was different in all three parameters. When the groups organized by sex were analyzed by age, the 20's group showed a statistical difference in all four parameters (Fo, Jitter, Shimmer, and NKR), when compared to the other two age ranges of 50's and 70's. We need to consider our standard parameter for the normal voice in the Korean elderly because the 50's and 70's age normal groups in our study are out of the current range of normal in MDVP.

본 연구에서는 차세대 염기서열분석(pyrosequencing) 기술을 이용해 조릿대(Sasa borealis) 대나무림의 낙엽층과 근권 토양 내 주요 군집인 방선균군집의 계통학적 특성을 분석하여 방선균 유전자원 다양성 확보를 위한 기반 연구를 수행하고자 하였다. 낙엽층 시료 내 세균군집은 2,588 OTUs, 다양성 지수 7.55로 나타났으며, 근권토양 시료의 경우 2,868 OTUs, 다양성 지수 8.15로 다양한 세균군집이 균등하게 분포하고 있는 것으로 확인되었다. 대나무림 토양시료 내 세균군집은 총 35개의 문으로 구성되었으며, Proteobacteria (51-60%), Bacteroidetes (16-20%), Acidobacteria (4-16%) 그리고 Actinobacteria (4-14%) 계통군이 주요 세균군집으로 확인되었다. 특히, Actinobacteria은 총 6목 35과 121속의 다양한 방선균이 분포하였으며, 전체 방선균군집의 83%가 Actinomycetales 목으로 확인되었다. 이들 Actinomycetales 목은 28개 과로 구성되었으며, Micromonosporaceae, Pseudonocardiaceae 그리고 Streptomycetaceae는 조릿대 대나무림의 낙엽층과 근권토양에서 풍부도가 가장 높고 변이가 적은 대표 방선균군집으로 확인되었다. In this study, a pyrosequencing was performed and analyzed to verify the phylogenetic diversity of actinomycetes in the bamboo (Sasa borealis) soil as a base study to obtain the genetic resources of actinomycetes. It was found that the rhizosphere soil had much various distribution in bacterial communities showing a diversity of 8.15 with 2,868 OTUs, while the litter layer showed a diversity of 7.55 with 2,588 OTUs. The bacterial community in the bamboo soil was composed of 35 phyla and the predominant phyla were Proteobacteria (51-60%), Bacteroidetes (16-20%), Acidobacteria (4-16%) and Actinobacteria (4-14%). In particular, Actinobacteria including Micromonosporaceae and Streptomycetaceae had a diverse distribution of actinomycetes within the six orders, 35 families and 121 genera, and it was characterized that about 83% of actinomycetes within Actinomycetales belonged to the 28 families. Among the dominant actinobacterial populations, Micromonosporaceae, Pseudonocardiaceae and Streptomycetaceae were representative family groups in the bamboo soils.

Development and evaluation of a competitive enzyme-linked immunosorbent assay using a monoclonal antibody for diagnosis of severe fever with thrombocytopenia syndrome virus in bovine sera

이효진,Eun-Ju Kim,최정수,Ji Youn Lee,조인수,신연경 대한수의학회 2016 Journal of Veterinary Science Vol.17 No.3

Severe fever with thrombocytopenia syndrome (SFTS) caused by the SFTS virus (SFTSV), a phlebovirus in the family Bunyaviridae, is an emerging tick-borne infectious disease that impacts humans. This disease manifests as a decreased blood cell count and multi-organ failure, with a case-fatality rate of more than 12% in China. Because vaccines or antiviral drugs for the treatment of this disease are not available, monitoring the SFTS circulation in animals and controlling the tick-mammal cycle are important for preventing SFTS. Monoclonal antibodies against the recombinant nucleoprotein of SFTSV were generated to develop a competitive enzyme-linked immunosorbent assay (cELISA) for the detection of antibodies against SFTSV infection in cattle. The specificity and sensitivity of cELISA was assessed by comparing the results of this assay to those of an immunofluorescence assay (IFA). The results of the cELISA using 416 field bovine serum samples and laboratory-immunized positive sera showed 98.1% consistency with those of the IFA. The cELISA used in this study did not show cross-reactivity with antisera against other viral cattle diseases. The cELISA presented in this study can be applied to detect antibodies against SFTSV in cattle.

이효진,이재송,최열,Lee, Hyo Jin,Lee, Jae Song,Choi, Yeol 대한토목학회 2015 대한토목학회논문집 Vol.35 No.6

본 연구는 사회학적 범죄이론에 근거하여 도시 지역의 특징과 범죄 발생 간의 관련성을 규명함으로써 효과적인 범죄예방 대책을 수립하는데 도움이 되고자 하였다. 연구를 위하여 지난 8년간(2005~2012) 대검찰청의 범죄데이터와 지역별 통계연보 등을 통한 인구사회학적 데이터를 이용하여 패널데이터를 구축하였고, 부산시의 16개의 구 군을 대상으로 패널모형으로 분석하였다. 분석결과를 바탕으로 범죄 발생을 줄이고, 범죄예방을 위해서는 첫째, 일반적인 범죄 예방책보다는 지역의 특성에 적합한 정책이 필요하다. 둘째, 범죄연구에 필요한 구체적이고, 정확한 범죄데이터를 활용할 수 있는 제도적 시스템이나 정책이 필요하다. 셋째, 앞으로도 사회과학분야의 제도와 함께 도시공학 및 여러 학문들이 연계된 연구의 수행이 이루어져야 할 것이다. This study, based on the sociological crime theory, is to examine the relation between urban characteristics and the incidence of crime, helping establish effective crime prevention measures. For doing so, the study employs crime data from the Supreme Prosecutors' Office and socio-demographic data including the regional Statistical Yearbooks -both from 2005 to 2012- to build the study's panel data, and analyzes the panel model on the 16 subordinate districts in the city of Busan. To reduce the incidence of crime and prevent crimes from occurring based on the analysis results, first, prevention measures specific to each region by its attributes are needed rather than general ones; second, new institutional frameworks or policies are required for utilizing accurate crime data; third, interdisciplinary research in which various fields including urban engineering are associated to that of social science is necessary to further the study.

In this study, the effect of fixation methods, relaxation treatment and washing treatment on the comfortable properties of MDPPA/HMM treated cotton weft-knitted fabrics was studied. As a result, 1) Air permeability of knitted fabrics decreased after flame resistant treatment. Single jersey and 10G showed higher value of air permeability than those of interlock and 14G. Swelling agent and wet fixation method which increased the values of W/T and decreased the values of WC/W resulted in decreased values of air permeability. 2) $Q_{max}$ of knitted fabrics decreased after washing treatment. $Q_{max}$ of knitted fabrics increased with decreasing air permeability 14G showed higher value of $Q_{max}$ than those of 10G. 3) Water absorption of knitted fabrics increased after relaxation treatment. Water absorption of knitted fabrics increased with increasing the value of W/T. Water absorption of knitted fabrics is more affected by the structure of fabrics rather than the effect of treatment.

초음파 유도 흡인을 이용한 견갑 상 낭종의 치료 - 증례보고 -

이효진,김양수,Lee, Hyo-Jin,Kim, Yang-Soo 대한정형외과초음파학회 2012 대한정형외과 초음파학회지 Vol.5 No.1

견갑 상 신경의 압박을 초래할 수 있는 많은 질환중에서, 견갑 상 낭종에 의한 압박은 흔치 않으며, 많은 수에서 간과되거나 오진되기도 한다. 저자들은 견갑 상 신경 압박 증상을 초래하고 있는 낭종을 자기공명영상 및 초음파로 확진하였다. 환자의 증상은 견갑 상 신경 중, 하극 신경에만 국한되어 있었다. Neviaser portal과 같은 위치에서 초음파 유도하에 경피적 흡인을 시행하였다. 시술 8주 후 경과에서 재발 소견은 없었으며, 객관적인 기능 평가에서도 호전된 소견을 보였다. 견갑 상 신경의 압박이 의심되는 증상이 있으면, 우선적으로 초음파로 병변을 찾는 것에 주력해야 한다. 낭종의 압박에 의한 증상은 낭종의 단순 제거 혹은 축소로도 증상은 호전되기 때문이다. 하지만, 동반하고 있는 질환 혹은 원인 질환 등이 강력하게 의심될 경우, 추가적인 진단 후에 침습적인 치료를 요할 수도 있다. Among the various reasons that can cause entrapment of suprascapular nerve, suprascapular cyst is not commonly found and more often, overlooked or misdiagnosed. Authors experienced one case of suprascapular cyst causing suprascapular nerve entrapment confirmed by ultrasonography and MRI. Symptom of the patient was confined to infrascapular nerve. Percutaneous aspiration of cyst was done under the guidance of ultrasonography through Neviaser portal on out-patient department. After 8 weeks of follow-up, no recurrent lesion was found and objective functional improvement was identified. When clinicians confront with the symptoms compatible with suprascapular nerve entrapment, every effort should be put on finding lesion under ultrasonography before attempting any further cost-ineffective or time-wasting evaluation. Symptoms caused by space-occupying cyst will be soothed by simple decompression. However, always be aware of concomitant lesions that might be the reason for the cystic lesion and in some cases, further evaluation is inevitable.

이효진,윤홍식,한학,Lee, Hyo Jin,Yun, Hong Sic,Han, Hak 한국재난정보학회 2021 한국재난정보학회 논문집 Vol.17 No.2

연구목적: 최근 대형 사회재난이 잇따라 발생하면서 자연재난 뿐만 아니라 사회재난을 예방하고 피해를 저감하기 위해 많은 연구가 진행되고 있다. 하지만 연구 중 대부분이 일부 사회재난만을 다루고 있기 때문에 본 논문에서는 지자체에서 중점적으로 다루어야 할 사회재난 유형을 선정하여 효과적인 대책 마련을 위한 기초자료를 만들고자 하였다. 연구방법: 행정안전부에서 고시하고 있는 43종 재난 중 중복 또는 발생 이력이 없는 재난 등을 제외한 후 중점유형을 선정하기 위해 11종의 재난유형을 선정하여 데이터를 수집하였으며 위험지도로 지역별 위험유형을 도출하였다. 위험지도를 도출하기 위해서 각 세부지표를 리스케일링하여 0 ~ 1로 정규화를 하였으며 엔트로피 기법을 통해 가중치를 결정하였다. 연구결과: 그 결과 행정안전부에서 고시하고 있는 중점재난과 약 41%가 일치하였으며 나머지 중점 유형은 원자력사고, 공동구 사고 등 정보를 취득할 수 없거나 최근 20년 동안 발생하지 않은 재난이었다. 결론: 따라서 본 연구를 통해 사회재난의 효과적인 예방 및 복구계획을 수립하기 위해 지자체별 사회재난 중점재난을 제시하고자 하였다. Purpose: Recently, a series of large social disasters have led to a lot of research to prevent social disasters as well as natural disasters and reduce damage. However, this paper aims to select the types of social disasters that local governments should focus on and create basic data for effective countermeasures and mitigation efforts. Method: Among 43 types of disasters announced by the Ministry of Public Administration and Security, 11 types of disasters were selected and collected to select the main types of disasters, and risk types were derived by region with risk maps. In order to derive the risk map, each detailed index was rescheduled to be 0-1 and weights were determined through entropy technique. Result: As a result, about 41% of the major disasters announced by the Ministry of Public Administration and Security were consistent, and the rest of the major types were disasters that could not be obtained or have not occurred in the past 20 years. Conclusion: Therefore, in order to establish an effective prevention and recovery plan for social disasters through this study, it was intended to present social disaster-focused disasters for each local government.
