이 연구는 문헌 및 현장조사를 통해 동강유역 생태·경관보전지역의 지형·경관 자원을 조사하고 지도화 하였다. 이를 통하여 지형·경관 자원의 분포특성을 살펴보고 동강유역 생태·경관보전지역의 지형·경관자원에 대한 지속적인 관리방안 및 보전방안을 제시하고자 하였다. 연구결과 본 연구지역은 동강 양안의 하천지역 지형·경관자원과 평창군 한탄리의 고원형 카르스트지역 지형·경관자원, 연구지역 전역에 걸쳐 대소로 분포하는 석회동굴 지형·경관자원, 연구지역 경계의 산지지역 지형·경관자원 등 크게 4개의 지형·경관자원으로 분류할 수 있었다. 이들 지형·경관자원은 현재 관광객의 유입과 거주민의 편의성 확보를 위해 일부 훼손되거나 훼손압력이 높은 것으로 조사되었다. 따라서 1일 탐방객을 제한하거나 학술적 의미를 담은 안내판 설치와 같은 지형·경관 자원의 보전과 주민이익이라는 공동 이익 추구를 위하여 지형·경관 자원별로 맞춤식 보전대책이 필요할 것으로 판단된다. This study has focused on geomorphological landscape resources analysis at the Dong-gang River Ecological and Landscape Conservation Area through literature review and field survey. Some appropriate maps have been created for this study. This study intends to examine the distribution characteristics of geomorphological landscape resources at the Dong-gang River Ecological and Landscape Conservation Area, and suggests a solution to manage and maintain the resources. The result has shown that the resources can be divided into four categories : The Dong-gang`s riverside geomorphological landscape resources, Pyeongchang-gun Hantan-ri`s plateau and karst area, limestone caves in various sizes throughout the entire study area, and the mountainous regions close to the study area boundaries. The study concluded that these geomorphological landscape resources are partially damaged or likely to be damaged due to tourist inflow and also the quality of resident lives needs to be improved. Therefore, limiting the number of tourists entering the area or installing guides who provide information about the academic importance of such resources are necessary in terms of maintenance. There is also a need for a customized solution according to geomorphological landscape resources in order to secure benefits for the residents as well.

Dong‑Geun Seo,Jeong‑Soo Park,Gun ‑Ki Lee,Wang‑Sang Lee 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4

In this paper, a lightweight printed dipole antenna array with 3×2 beamforming network for wide unmanned aerial vehicle (UAV) communication coverage is presented. The proposed antenna consists of an upper substrate, a lower substrate, and two supports with a microstrip feeding. The upper substrate has a two-element printed dipole antenna array, and the lower substrate includes a beamforming feeding circuit and a ground plane as a refector of the proposed antenna array for gain improvement. For wide beam coverage, the proposed feeding network consists of three RF switches, one Wilkinson power divider, and one 90° hybrid coupler, and generates the wide beam using one broadside beam and two end-fre beams. Measured impedance bandwidth, peak gain, and half-power beamwidth (HPBW) of the proposed array operated from 5.03 to 5.15 GHz are approximately 2 GHz, 4.3 dBi, and 155°, respectively.

Analysis of Insulation Diagnosis for Generator‑Motor Stator Winding in Pumped Storage Power Plant

Soo‑Hoh Lee,Tae‑Sik Kong,Hee‑Dong Kim 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.3

In this study, insulation diagnostic tests were conducted on pumped storage power plant (PSPP) generator-motor stator bars with artifcially simulated defects in order to improve solutions to perform preventive maintenance and track insulation diagnostic data for generator-motors by proving the efectiveness of insulation indices. Moreover, ozone (O3) concentration was estimated in order to relate it to partial discharge (PD) in laboratory to ensure the efectiveness of ozone as another index for insulation deterioration. By performing an ofine PD test and ultraviolet (UV) observation on one of the generator-motors during overhaul, and an ozone concentration measurement for the identical machine after the overhaul, it was concluded that ozone estimation could be a powerful index for insulation diagnosis under actual operational conditions. It was further developed that ozone measurement is useful to detect not only discharges in slots as mentioned in some studies but also discharges at the end-winding as proven in this study. The fndings of this study are expected to contribute to more reliable maintenance of generator-motors in PSPPs by achieving elaborate insulation diagnosis via multiple diagnostic indices.

Park, Dong-Seok,Kim, Ji-Hoon,Min, Byung-Il,Oh, Soo-Myung 경희대학교 동서의학연구소 1999 INTERNATIONAL SYMPOSIUM ON EAST-WEST MEDICINE Vol.1999 No.1

Dong-Seok Park¹, Ji-Hoon Kim¹ and Byung-Il Min, Soo-Myung Oh,³¹Department of Acupuncture and Moxibustion, College of Medicine, ²Department of Physiology, College of Medicine, And ³East-West Medical Research Institute, Kyung Hee University,Seoul, Korea. Analgesic Effect of Manual Acupuncture and Electroacupuncture combined with Twirling Method. Proceeding of International Symposium on East-West Medicine Seoul. 187-200, 1999.-Twirling the needle (TN) is one of several needing methods frequently used for acupuncture in the oriental medicine. The present study was conducted to see if TN enhanced the antinociceptive effect produced by plain-or electroacupuncture in the rat tail flick test. Rats (Sprague-Dawley, 200-300g)lightly anesthetized with thiopental sodium(40mg/kg, i.p.) were used in the tail-flick test. The basal reaction time for tail-flick was 2 sec. For "plain" acupuncture(PA), a needle was inserted for 20 min into a Chock-samni (ST36) acupuncture point which (is located at the anterior tibial muscle and about 10mm below the knee joint). For electroacupuncture(EA), train-pulses(3 Hz,0.3-ms pulse width, 0.2-0.3mA) were applied to the inserted needle for the period of insertion. For combining TN with either PA or EA, TN was performed during the each acupuncture period. Two methods for TN were used; twirling 3 times for 1 second persisted for 1 min in every 5 mins(long-duration and long-interval;LDLI) and twirling 3 times for 1 second persisted for 10 sec in every 1 min(short-duration and short-interval;SDSI). PA and EA produced an increase in tail flick latency (TFL); peak increases were 21.3±5.1% and 42.1±17.3% of the pre-acupunture control, respectively, and occurred immediately after cessation of 20min-acupuncture. Performing TN combined with PA increased TFL more than PA itself by showing a greater peak increase in TFL when performed with a SDSI-TN than with a LDLI-TN(60.6±12.5% and 42.7±22.7% of the pre-acupuncture control, respectively). Performing TN combined with EA also increased TFL more than EA itself and a greater peak increase in TFL was observed with a SDSI-TN as compared to a LDLI-TN(77.5±13.8% and 67.3±14.0% of the pre-acupuncture control, respectively). These results indicate that TN enhances both PA-and EA-produced antinociception where an greater enhanced antinociception than a LDLI-TN. It is suggested that performing a SDSI-TN combined with EA seems to be one of the most effective ways to produce analgesia.

Coronary artery aneurysms are detected with increasing frequency because of the routine use of coronary angiography in the diagnosis and management of coronary artery disease. Although some coronary artery aneurysms are congenital or inflammatory, most are atherosclerotic. The prognosis of atherosclerotic coronary artery aneurysm may depend on the morphology of the aneurysm or the presence of coexisting obstructive disease. Coronary artery aneurysms have been also reported to occur after ballon angioplasty, directional athrectomy, laser angioplasty, and stent implantation with a frequency of 2% to 4%. The long-term outcome of post-intervention coronary artery aneurysm is unknown. We report two cases of the development of a coronary aneurysm 6 months after stent implantation as a treatment of severe obsructive coronary artery disease.

최희동,이명재,고동완,곽성관,김동식,정관수 慶熙大學校 레이저 工學硏究所 2002 레이저공학 Vol.13 No.-

In this work, we examined the electrical and mechanical characteristics of TFD devices for various top electrode materials by measuring barrier height and performing ASE depth profile. It was found that the shift of current-voltage(Ⅰ-Ⅴ) characteristics of TFD device depends on the top electrode material. The main reason of the asymmetry in Ⅰ-Ⅴ curve was the differences in barrier height of top and bottom electrodes, and chemical composition at the interface region between top electrode and insulator layer also was important reason. The barrier heights(φ_B) evaluated from temperature dependence of the Ⅰ-Ⅴ relation are 0.7795(Al) 1.0287(Ti) and 1.2928(Ta) eV.

Pansori as a solo opera unique in the world is a sound art representing Korea which was registered in the worldwide intangible cultural heritage. Despite this fame and worth, it is in a situation that a special theater of pansori is almost none in Korea, and presently running performance halls are mostly old after their establishment and most of them should be remodeled. Although Dongri Korean classical music hall which was built in 1990 among them is small in scale, it has a unique type and worth as a representative special theater of Pansori. However, it has passed more than 20 years in its establishment and it is in a stage of remodeling the design in presence. The most important thing in special theaters of Pansori like Dongri Korean classical music hall is to secure acoustic performance proper to Pansori performances. In this point, this study measured and evaluated constructional acoustic performance aiming at Dongri Korean classical music hall which is in the stage of remodeling the design. Based on these data, to build the best domestic special theater of Pansori is the meaning of the study.

[18F]FDG PET을 이용한 강박증 환자에서 뇌 포도당 대사의 이상에 관한 연구

권준수,이동우,이재성,최정임,이동수,정준기,조맹제,이명철,류인균 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

연구목적: 강박증에 대한 기능적 뇌영상 연구들에서 강박증 환자들의 안와전두엽과 미상핵의 대사율 증가 소견이 비교적 일과되게 발표되어 왔으며, 전두-피질하 회로의 이상이라는 이론이 수립되기도 하였다. 그러나 기존의 연구들은 강박증의 유병기간에 따른 구분없이 시행된 연구였고, 영상분석 방법에 있어서도 관심영역 방법을 이용했다는 한계를 지니고 있다. 본 연구의 목적은 첫째, 강박증의 유병기간에 따라 환자군을 구분하여 PET 영상소견을 분석함으로써 유병 기간에 따른 차이가 있는지를 조사하였으며, 둘째, 강바증 환자의 포도당 양전자방출 단층촬영(18-Fluor-deoxyglucose Positron Emission Tomography : FDG-PET) 영상분석에 통계적 매개변수 지도법(Statistical Parametric Mapping : SPM)을 이용함으로써 강박증의 병인기전 및 강박증상과 뇌기능 간의 관계를 명확히 규명하고자 하였다. 방법: 구조적 면담도구(Structured clinical interview for DSM-IV : SCID-IV)를 적용하여 진단된 12명의 강박증 환자들과 10명의 정상 대조군에 대해 FDG-PET을 촬영하여 SPM으로 분석하였다. PET 촬영 전 적어도 4주 동안에는 약물복용을 하지 않은 상태였다. 결과: 1) 환자군과 대조군의 비교 : 강박증 환자군은 대조군에 비해 양측 두정 영역의 대사율이 유의하게 감소되어 있었으며(P<0.01). 대사증가를 보인 영역은 없었다. 강박증의 유병기간이 10년 이상인 만성강박증 환자 4명은 양측 안와전두엽에서 유의한 대사증가 소견을 보였으며(P<0.01), 양측 두정영역에서 유의한 대사감소 소견을 보였다 (P<0.01), 유병기간이 10년 이하인 환자에서는 전체 환자군의 분석에서와 마찬가지로 대조군에 비해 유의한 대사증가 소견을 보인 영역은 없었으며, 양측 두정엽 부위에서 유 의한 대사 감소 소견을 보였다.(P<0.01). 2) 강박증상의 심각도와의 상관관계 분석 : 우측 두정엽의 대사율은 강박장애 척도 점수와 유의한 음의 상관관계를 보였으며(p<0.01), 양측 시상 영역의 대사율은 예일-브라운 강박장애 척도의 강박장애척도 점수와 유의한 양의 상관관계(p<0.01)를 보였다. 결론: 본 연구는 결과는 기존의 연구들에서 보고된 안와전두엽의 대사 증가 소견이 강박증의 만성화로 인해 나타나는 2차적 장애이며, 두정엽의 대사 저하가 보다 1차적인 장애일 가능성을 시사한다. Baxter가 수립한 전두-피질하 회로 이론은 두정엽의 이상을 포함하는 전두-두정엽 복합체 이론으로 확장되어야 할 것이다. Objectives: Functional imaging studies on obsessive-compulsive disorder(OCD) subjects have repeatedly reported increased metabolism in orbitofrontal lobes and caudate nucleus, resulting in the "frontal-subcortical" circuit abnormality theory. Limitations of the previous studies to date include little consideration for the duration of illness, and the use of regions of interest methods, as an image analysis method. Our study objectives are 1) to include the duration of illness as an important study variable, and 2) to use Statistical Parametric Mapping(SPM) method in order to tap relations between the brain function and the psychopathology and symptoms of OCD. Methods: The [18] fluorodeoxyglucose positron emission tomography(FDG-PET) scans of OCD subjects and normal comparison subjects, as diagnosed by the Structured Clinical Interview for DSM-IV(SCID-IV), were analyzed using SPM. Results: 1) Comparison of OCD and control groups : OCD subjects had significantly decreased metabolism in both parietal lobes and didn't have any areas of increased metabolism in comparison to comparison subjects(p.<0.01). four OCD subjects with the illness duration of 10 years or longer, had significantly increased metabolism in both orbitofrontal lobes<p<0.01). OCD subjects whose illness duration is shorter than 10 years didn't have any areas of increased metabolism and had significantly decreased parietal lobe metabolism, as in the analyses of all subjects(p<0.01). 2) Correlation analysis between areas and symptom severity : Metabolism of both thalamic sreas showed significant positive correlation with Yale-Brown Obsessive-Compulsive Scale(Y-BOCS) scores(p<0.01). Metabolism of right parietal area showed significant negative corre lation with Y-BOCS scores(p<0.01). Conclusions: The current findings suggest that the increased metabolism in orbitofrontal lobe, previously rported, may be a secondary phenomenon due to the extended illness dur- ation and that decreased metabolism in the parietal lobes are primary abnormality in OCD subjects. Thus Baxter's fronto-subcortical circuit theory should be extended into "fronto-pari-etal" complex theory, which includes the parietal lobes.
