본 연구에서는 설악산국립공원에 서식하는 멸종위기종 산양과 서식지의 보전 및 관리를 위해 산양의 분변 및 카메라 트랩을 이용한 개체수와 서식지 이용 분석을 2010~2014년 동안 수행하였으며 생태학적 조사 방법(흔적조사, 카메라트 랩조사)을 사용하였다. 분변 조사와 카메라트랩핑 분석 결과 각각 166개체 및 251개체의 산양이 설악산국립공원에 서식하고 있는 것으로 나타났다. 흔적조사(분변)를 통한 서식지 이용 특성 분석에서 산양은 경사도 35°~60°, 고도 600~700m, 향 북동, 수계와의 거리 0~50m, 도로와의 거리 300~600m, 활엽수림을 가장 선호하는 것으로 나타났다. 카메라트랩 조사를 통한 산양 개체군 구성, 주간(07-18시)이 56.5%, 야간(18-07시)이 43.5%로 산양의 활동성을 파악하였다. 이러한 산양의 개체수와 서식지 이용 특성 분석은 향후 그들이 살아가는 서식지의 보전과 서식지의 관리를 위한 중요한 기초 자료로 활용될 수 있을 것이다. This study was conducted investigate population size and habitat use for the conservation and management of the endangered long-tailed goral in the Seoraksan National Park using feces and camera trap during 2010 to 2014 (track survey, camera trap). As a result of feces tracking and camera trap, its population size was estimated as 160 (camera trap)~251 (feces) individuals in the Seoraksan National Park. The goral prefer 35°~60° (slope), 600~700m (elevation), NE (aspect), 0~50m (distance to stream), 300~600m (distance to road) and bread-leaved forest (forest type) according to field tracking of fecal. Based on field camera trap, we estimated the age classes of goral populations and activity of gorals during day-time (07-18 time, 56.5%) and night-time (18-07 time, 43.5%). Such analyses of population size and habitat use of the goral could be applied as important fundamental data for conservation of gorals and management of their habitats.

Plate heat exchanger consists of thin, rectangular, pressed sheet metal plates that are sandwiched between full peripheral gaskets and clamped together in a frame. The frame has a fixed end-cover plate, fitted with the connecting ports, which is bolted together with a movable cover plate to hold the embossed plates in between; the top and bottom carrying bars allow proper alignment of the plate stacks. When compared with the well-established shell and tube heat exchangers, the plate heat exchanger shows a lot of advantages like high NTU values, compactness, low cost, multi duties and reduced fouling etc. Plate heat exchangers are often used to transfer heating or cooling water which is produced in the energy production( district heating or district cooling) facilities to residential areas and industrial parks. The district cooling systems of Middle East are the biggest market of plate heat exchanger, but the technical specifications for cooling system are different from the domestic one. To achieve its specifications, the new plate heat exchanger was developed, and its thermal performance results are introduced in this paper.

Clinical Significance of Classification of Graves` Disease According to the Characteristics of TSH receptor Antibodies

(Won Bae Kim),(Hyun Kyung Chung),(Young Joo Park),(Do Joon Park),(Hong Kyu Lee),(Bo Youn Cho) 대한내과학회 2001 The Korean Journal of Internal Medicine Vol.16 No.3

N/A Background:It has been widely accepted that the epitope (s) and/or functional characteristics of thyrotropin receptor antibodies (TSHRAb) from Graves` patients are heterogenous among patients. However, the clinical significance of such heterogeneity has not been systematically evaluatedyet. We were to elucidate and find the clinical significance of heterogeneity for TSH receptor antibodies in Graves` disease. Methods:We measured stimulating TSHRAb (TSAb) activities using CHO-hTSHR cells, FRTL-5 cells and chimeric receptor expressing cells (Mc1+2 and Mc2), specific blocking TSHRAb (TSBAb) activities using Mc2 cells and TBII activities using porcine thyroid membrane in 136 patients with untreated hyperthyroid Graves` disease. Results: Based on various TSHRAb activities from each patient, the patients could be categorized into 7 subgroups by cluster analysis; 1) Group 1 (n=41) was characterized by moderate TSAb activities bothin CHO-hTSHR cells and in FRTL-5 cells, typical TSAb epitope, rare blocking antibodies and high TBII activities. 2) Group 2 (n=16) was characterized by the presence of blocking TSHRAb in most patients, albeit the other characteristics were the same as those in Group 1. 3) Group 3 (n=19) patients had low TSAb activities bothin CHO-hTSHR cells and in FRTL-5 cells, seldom had blocking TSHRAb, but they had high TBII activities. 4) Group 4 (n=30) could be categorized as `mild disease` group, as they had low activities in all kinds of TSHRAb assay and had low antim icrosomal antibody activities. 5) Group 5 (n=14) was characterized by moderate TSAb activities with atypical epitope (s), rare blocking TSHRAb and moderate TBII activities. 6) Group 6 (n=10) patients had veryhigh TSAb activities with typical epitopes, seldom blocking TSHRAb and low TBII activities. 7) Group 7 (n=6) was characterized by very high TSAb activities with atypical epitopes and high TBII activities. Pretreatment serum thyroid hormone level was low only in group 4 patients compared to the other 6 groups (p<0.05). The size of goiter was significantly larger in those in group 1 and group 3 (p<0.05) compared to the other 5 groups. The prevalence of clinically significant ophthalmopathy was higher in group 2 patients than the other 6 groups (50%vs.27.5%,p=0.06). Among 6 kinds of TSHRAb activities, only the blocking TSHRAb activity was significantly associated with the presence of ophthalmopathy in multivariate analysis. Conclusion:These results suggest that the differences inepitopes for TSAb or the presence of blocking TSHRAb is not a major factor in determining the degree of thyrotoxicosis in Graves` disease. Although the pathogenic mechanism is not clearyet, we suggest that patients with ophthalmopathy have different TSHRAb repertoire from those without ophthalmopathy in Graves` disease.

박정관,조규성,남기상 全北大學校 基礎科學硏究所 1989 基礎科學 Vol.12 No.1

This research aims to study origin by trace elements (Cu, Cr Pb, Ni, Mn, Li,Zn) of 225 samples of the gneisses that receive high metamorphism in sannae-myeon area, Namwon-gun. I have studied average abundance, abundance range and frequency distribution of each elements, and considered geochemical feature of the trace elements in the shale and granite. Abundance of Cu, Cr, Ni, in the shale of sedimentary origin is higher than that in the granite of igneous origin. Abundance of the trace elements in the porphyroblastic gneiss, granitic gneiss and pegmatitic gneiss is very similar to the that in the shale with the biotite gneiss, but that in the leucocratic gneiss is less than in the shale and it is similar to the granite. Frequency distribution of the rocks of sedimentary origin is irregularly widely dispersion, but that of igneous origin is distributed narrowly around maximum frequency. Therefore the porphyroblastic gneiss, granitic gneiss and pegmatitic gneiss is paragneiss with the biotite gneiss, and the Leucocratic gneiss is orthogneiss. This result is in accord with geological field survey and study on the metamorphism(Kim O.J. etal.,1964;Kim H.S., 1970,1973; Lee S.M., 1980,1981)

조진영,이영준,박영국,정규림 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.5

이 연구는 각 유형의 부정교합과 중심교합위-중심위 변위량 간의 상호관련성을 구명하기 위하여 시행되었다. 각 부정교합자 군에서 중심교합위-중심위 변위를 3차원적으로 비교 평가하고, 각 안면골격 형태의 특징에 따른 변위량의 차이 유무를 분석하고, 각 유형의 부정교합 골격형태에서 중심교합위-중심위 변위와 두개안면골격 계측요소간의 상관성을 검정하였다. 242명의 부정교합자를 대상으로 중심교합위 상태에서 얻어진 측모두부X선규격사진을 계측하고 이들을 수평적, 수직적 관계에 의하여 9군으로 분류하였다. 또한 이들로부터 중심위와 중심교합위에서의 교합기록을 채득하고 face-bow로 안궁이전을 한 뒤 석고모형을 교합기에 중심위 상태로 탑재하였다. CPI를 이용하여 중심위와 중심교합위의 하악과두위치를 측정하고 이들과 각 군의 측모두부X선규격사진 계측치와의 상관성을 검정하기 위하여 통계처리한 결과 다음과 같은 결론을 얻었다. 1. 중심교합위-중심위 변위의 양과 방향에서 좌측과 우측은 중등도의 상관관계를 보였으며 전후방보다는 상하변위의 좌·우측 상관성이 다소 높았다. 2. Ⅱ급 부정교합군이 Ⅰ급과 Ⅲ급 부정교합군에 비해 좌우측간의 중심교합위-중심위 변위가 높은 상관관계를 보였다. 3. 각 부정교합군에서의 중심교합위-중심위 변위 유형은 유의한 차이가 없었다. 4. 중심교합위 상태의 측모두부X선규격사진상에서의 안면골격의 형태요소와 중심교합위-중심위 변위간에는 상관성이 적었다. 5. Ⅱ급 brachyfacial skeleton과 Ⅲ급 mesofacial skeleton의 일부 계측치에서 CPI수치를 예측할 수 있는 항목들이 나타났다. 중심교합위-중심위 변위의 양과 방향은 특정한 안면형태요소와는 무관하며 하악과두의 위치변이는 부정교합양태나 안면골격형태와 관계없이 발현되었다. The present study was performed to prove the relationship between CO-CR discrepancy and facial skeletal type. In this study, 242 subjects were randomly selected and devided into 9 groups(devided into class Ⅰ,Ⅱ, Ⅲ by ANB and each one devided into dolicho-, brachy-, mesofacial skeleton by Ricketts' vertical index). Lateral cephalometric radiographs with the mandible in centric occlusion were taken and measured and CO and CR bites were registered on all subject. Diagnostic casts were mounted on Panadent articulator using an estimated face-bow and centric relation bite registration. The amount and direction of CO-CR discrepancy present was recorded using a Condylar position Indicator(CPI) and a centric occlusion wax bite registration. CPI measurements and cephalometric measurements were statistically analyzed. The finding of this study can be summerized as follows: 1. There is little correlation between right and left sides for magnitude or direction of CO-CR discrepancies. The correlation between the magnitude of CO-CR discrepancy of left A-P and right A-P is higher than that of left S-I and right S-I. 2. Correlation of Class Ⅱ malocclusion group was higher than that of the other groups between the magnitude of Co-CR discrepancy of left CPI and right CPI. 3. There is no difference between the pattern of Co-CR discrepancy of 9 malocclusion groups. 4. There is very little, if any, correlation between Skeletofacial measurements and CO-CR discrepancy. 5. In the Class Ⅱ brachyfacial skeleton and ClassⅢ mesofacial skeleton there was Lateral cephalometric measurements by that we predict CPI measurements was detected. That was overbite, overjet, upper gonial angle, lower gonial angle, saddle angle, articular angle, convexity of point A, ANS-Me/Na-Me, PCBL/RH, Posterior FH/anterior FH.

This study was conducted in 1986 to investigate the vivaparous germination in rice. Two varieties, Daeseongbyeo and Chilseongbyeo, were transplanted on May 25 and June 5 and panicles were harvested 5 times with the interval of 5 days beginning 30 days after heading. Panicles were seeded in incubator at 20℃ right after harvest and after drying and storage to observe the germination. Rate of viviparous germination of Daeseongbyeo was higher than that of Chilseongbyeo regardless of the seeding time. Rate of vivaparous germination of May 25 transplanting was higher than that of June 5 transplanting. Germination of Daeseongbyeo was not afftected by seeding time. Viviparous germination rate of Daeseongbyeo appeared to be increased as the harvesting was posponded. On the other hand, Chilseongbyeo did'nt germinate when seeded right after harvesting and rate of vivaparous germination was decreased as the harvesting was postponded. Vivaparous germination was higher in the order of top > middle > bottom part on a panicle, while grains on the primary branches showed higher vivaparous germination than those on the secondary branches.

趙東三,孫錫龍,金鍾煥,尹太,朴成圭,權圭七 충북대학교 농업과학기술연구소 1988 農業科學硏究 Vol.6 No.1

This study was conducted in 1987 to investigate the viviparous germination in rice. Six varieties, i. e., Daeseongbyeo, Sangpungbyeo Hwaseongbyeo, Taebagbyeo, Chilseongbyeo and Samgangbyeo were used for this experiment. Seedlings were transplanted on May 25 and dune 5 and panicles were harvested 5 times with 5 days interval beginning 25 days after heading. Panicles were incubated at normal temperature right after harvest to observe the germination. Rate of viviparous germination of Japonica type was higher than that of Indica type. The early varieties such as Daeseongbyeo, showed high viviparous germination. Rate of viviparous germination of May 25 transplanting was higher than that of June 5 transplanting. Viviparous germination rate of Japonica type appeared to be increased as the harvesting was postponed. On the other hand, Indica type didn't show viviparous germinate. Based on this study the optimum harvesting time of tested varieties appeared to be between 40 to 45 days after heading.

朴元千,曺圭大 제주대학교 1969 논문집 Vol.1 No.-

Generally W hook line in several kinds of makers is strong, while L hook line is less strong than the others in both dry and wet condition. Elongation are the greatest in L hook line, as compared with the others. 1. Nylon monofils hook Line made in Korea vary in the formula diameter according to number of hook line and that difference is about 0.04mm∼0.06mm. 2. Value of breaking strength T feels in proportion as increase of number of hook line. Value of mean breaking strength in dry condition are increased about 0.30kg-1.50kg than that of wet condition in without knot. In difference value of mean breaking strength among three makers are 0.31∼8.4kg in dry condition and 0.15kg-10.76kg in wet condition. 3. Generally, value of standard devation σ are according to increase of hook line numbers both dry and wet condition. In dry condition, standard devation σ makes minimum 0.063 in M3 and maximum 1.238 in W26, in wet condition it shows minimum 0.000 in W3 and maximum 1.093 in L26. 4. In dry condition, value of coafficient C. V. was minimum 1.525 in W6 and maximum 8.98 in M6, in wet condition it was maximum 14.537 in W6 and minimum 0.00 in W3. Generally, having big value of and small value of this C.V. is saying that hook line are uneven and even respectively in quality and size. 5. Elongation ratio are minimum at all number of hook line less than 10%-20% loading, that as increasing more than 90% loading are break in quickly increase. Elongation ratio is maximum 65.0% in L26 and minimum 24.0% in 3L.

위염전은 위의 비정상적인 회전으로 생기는데 급성증에서는 진단이 늦어질 경우 치명적일 수도 있으나, 만성증의 경우는 비특이적 위장관 중상을 나타내며, 치료되지 않을 경우 수년 동안 증상이 지속될 수도 있다. 최근 저자들은 소화불량, 식후 상복부 동통을 주소로 내원한 환자에서 만성위염전 2 례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Gastric volvulus is an abnormal rotation of the stomach. Gastric volvulus may present as an emergency or as a chronic condition. Acute volvulus si potentially lethal if unrecognized, while a chronic volvulus may cause symptoms for years if not treated. Gastric volvulus may be more common than previously estimated. Approximately 700 cases have thus far been documented. In patients with vague upper abdominal pain, bloating, vomiting, early satiety and weight loss, chronic gastric volvulus are reported and the related literature reviewed. The clinical presentation, diagnosis, and treatment are treatment are discussed. Features of acute and chronic volvulus are compared.
