‘금촌조생’ 품종은 농촌진흥청 원예연구소 나주배연구소에서 1971년 ‘금촌추’의 품질을 개선하기 위해 당도가 높고 육질이 유연한 ‘단배’를 교배하여 1982년 1차 선발되었고, 1997년부터 5년 간 지역적응시험을 거쳐 2001년 최종 선발 및 품종보호출원 되었다. 수세는 비교적 강하고, 수자는 반개장성이다. 꽃가루가 풍부하며, 주요 재배품종과 교배친화성을 보인다. 또한 흑반병에 대하여 강한 포장저항성을 나타내었다. 숙기는 재배중인 ‘원황’ 품종보다 약 5일 정도 늦은 9월 3일로 추석에 출하하기 알맞은 품종이다. 과형은 ‘금촌추’와 같은 도원추형이고, 과피색은 황갈색이다. 과중은 593g이고, 당도는 13.2Bx이다. 육질은 유연하며 과즙이 풍부하고, 석세포가 없어 식미가 매우 우수하다. 그러나 과육선숙형 품종으로 원예적 수확기에도 과피에 녹색이 남지만, 완숙과가 되면 황갈색으로 착색된다. 상온저장 기간은 20일 정도로 다른 조생종에 비해 저장력은 좋은 편이다. ‘Geumchonjosaeng’ pear cultivar (Pyrus pyrifolia var. culta Nakai) originated from the cross between ‘Imamuraaki’ and ‘Danbae’ to improve the fruit quality of ‘Imamuraaki’ cultivar in 1971 at Naju Pear Research Institute of National Horticultural Research Institute (NHRI), Rural Development Administration (RDA). It was preliminarily selected in 1982 and named in 2001. The tree habit shows vigorous growth and upright spreading. It carries abundant pollen grains and shows cross compatibility with leading cultivars. Also it shows high resistance to black leaf spot (Alternaria kikuchiana) in the field condition. Optimum harvest time is around Sep. 3, which is 5 days later than that of ‘Wonwhang’, and it could satisfy consumer’s demand for high quality pear fruit in “Chuseok”. The obovate fruit shape resembles maternal parent, ‘Imamuraaki’ and skin color is green yellowish brown at normal harvesting time and gradually turned to yellowish brown at full ripennig state. Fruit weighs about 593 g, and the soluble solid content is 13.5 ˚Bx. The flesh is very soft and juicy and, rendering good eating quality. Shelf life is about 20 days under the ambient temperature, and it is a relatively long period as compare with other early season cultivars.

Objectives : Lumbar disc herniations at the L1-L2, L2-L3, and L3-L4 level are rare. The purpose of this study is to observe the variable clinical finding of upper lumbar disc herniations and to provide proper treatment modality. Patients and Methods : Between 1998 Jan. and 1999 Dec., seventeen patients with upper lumbar disc herniations who were undergone surgery in our institute were retrospectively evaluated. Patients were evaluated based on following factors : age, sex, aggravating factor, symptoms and signs type of disc herniation, type of surgery, and outcome of post-surgery. Results : The incidence of lumbar disc herniation at the level of L1-2, L2-3 and L3-4 is 6.1% with declining frequency as the level ascends. The peak age incidence is 6th decade in both sex. Preoperative symptomes and signs are variabe. In sixteen cases, posterior approach was done. In these cases, twelve cases were performed microscopic partial hemilaminectomy, and four cases with spinal stenosis were performed total laminectomy and posterior screw fixation with bone fusion. In one case, lateral extracavitary approach was done. In results of operation, fourteen cases showed more than good grade(82%). Conclusion : The age incidence of lumbar disc herniations at the level of L1-2, L2-3 and L3-4 older than lumbar disc herniations at the lower level of L4-5 and L5-S1. The signs and symptoms are variable. In our cases, most of the patients were performed posterior approach with microscopic partial hemilaminectomy except the patients combined spinal stenosis. One case was performed a lateral extracavitary approach because the risk of the cord and cauda equina injuries. The prognosis of upper lumbar disc herniations after treatment with only microscopic partial hemilaminectomy and diskectomy is comparable with the prognosis of lumbar disc herniations at the lower level.

In this paper, a new shape feature extraction method of the objects using surface curvatures is described. First, the values of the H & K are calculated from range data as given input. Then objects are assigned in the form of 8 primitives by the signs of the H & K values. But existing methods have the difficulties with the complex object. Therefore, We propose the method for the complex primitives such as cone ridge and cone valley. Finally, the effectiveness of this paper is demonstrated by several experiment.

Objectives: Symptoms arising from spinal cord tumor are often insidious in onset and nonspecific in nature. To make the subtle initial signs and symptoms of these tumors more apparent to clinicians, we retrospectively analyzed the data of spinal cord tumor patients who were misdiagnosed as degenerative spine disease. Methods: We reviewed history, symptom, sign, radiological study, and pathologic diagnosis of 19 spinal cord tumor patients who had been operated as degenerative spine disease, especially duration and description of symptoms and sign before an accurate diagnosis was made. Results: Average duration of delay before an accurate diagnosis was made was 178.4 days(range: 23~303). Common symptom and signs on neurologic examination included aggravation of pain(8 cases; 47.1 %), and neurologic decline(9 cases; 52.9%) The misdiagnosis included a herniated lumbar disc(16 cases; 94.1%), lumbar stenosis(1 case; 5.9%). Inappropriate treatment for these misdiagnoses included 5 percutaneous lazer discectomies, 9 discectomies, 3 chemonucleolysis, 2 posterior lumbar interbody fusions with cages. Conclusion: When a patient has symptoms that appear to be out of the ordinary, surgeons should suspect other spinal disease including the spinal cord tumor.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

본 연구는 복합레진의 표면 연마에 의한 표면 거칠기가 표면 색상과 투명도에 어떤 영향을 미치는가를 알아보고자 시행하였다. Charisma (Heraeus Kulzer GmbH, Domagen, Germany)의 B1과 A3, Esthet-X (DENTSPLY Caulk, Milford, USA)의 B1과 B3 레진으로 거칠기에 따른 표면 색상을 평가하기 위한 직경 8㎜, 두께 5㎜의 시편을 제작하고, Sof-Lex finishing & polishing system(3M, ESPE Dental Products. St. Paul USA)의 C, M, F, 및 SF 디스크로 시편의 한쪽 면을 연마하였으며, 연마 전 Mylar strip으로 압축된 면을 대조군으로 하였다. 거칠기에 따른 투명도의 차이를 평가하기 위한 두께 1 ㎜의 시편을 Charisma의 A3로 제작하여, 한쪽 면을 600, 1000, 1500 및 2000번 사포로 연마하였다. 각 시편의 연마 전과 후, 연마면의 CIE L^(*)a^(*)b^(*)값과 1 ㎜ 시편의 백색과 흑색 배경판 상에서의 Y값을 spectrophotometer인 Spectrolino (GretagMacbech, Regensdorf, Switzerland)를 사용해 측정 분석하였으며, 각 시편의 연마 전과 후의 평균 표면 조드 (Ra)값을 Surface Roughness Tester SJ-301 (Mytutoyo, Tokyo, Japan)로 측정했다. L^(*)값은 재료와 색상에 상관없이 가장 거친 Sof-lex C 디스크로 연마한 군에서 가장 높은 값을 보였으며 (p < 0.05). Esthet-X B3군을 제외한 모든 군에서 Ra값이 감소함에 따라 L^(*)값도 낮아졌다. a^(*)값은 표면 거칠기에 따라 특정한 변화 양상을 보이지 않았으며, b^(*)값은 Esthet-X B1군을 제외한 모든 군에서 Sof-lex SF 디스크로 연마 시 가장 높은 값을 보였으며 (p < 0.05), Charisma B1과 Esthet-X B3군에서 Ra값과 비교적 높은 상관 관계를 보였다. Contrast ratio는 1000번과 1500번 사포로 연마한 군간을 제외한 모든 군 간에 유의한 차이를 보여으며 (p < 0.05). 표면 거칠기가 감소함에 따라 contrast ratio도 감소하였다(R2 = 0.801). The objectives of this were to evaluate the effect of surface roughness on the surface color and translucency of the composite reins. Two composite resins (Esthet-X, Dentsply, Milford, USA and Charisma, Kulzer, Domagen, Germany) were used to investigate the surface color. Charisma was used to investigate the translucency. 40 disc samples (diameter: 8 ㎜, thickness: 5 ㎜) were made by each product to measure the surface color. Ploymerized each sample's one side was treated by Sof-Lex finishing and polishing system (Group C, M, F, SF). 40 disc samples (diameter: 6 ㎜, thickness: 1 ㎜) were prepared to measure the opacity. 1 ㎜ samples were ground one side with #600, #1000, #1500 and #2000 sandpapers. CIE L^(*)a^(*)b^(*) values of each 5 ㎜ thickness samples, and XYZ values of 1 ㎜ thickness samples on the white and black background were measured with spectrophotometer (Spectrolino, GretagMacbeth, Regensdorf, Switzerland). Mean surface roughness (Ra) of all samples before and after surface treatment was measured using the Surface Roughness Tester SJ-301 (Mytutoyo, Tokyo, Japan). Regardless of type and shade of the composite resin, L^(*) values measured in group C were higher than others (p < 0.05), and L^(*) value decreased as the Ra value decreased except B3 shade of Esthet-X. But there were no significant difference in a^(*) values among groups. In control group and SF, highest b^(*) values were measured (p < 0.05), except B1 shade of Esthet-X. Contrast ratio decreased as the Ra value decreased (p < 0.05). With the above results, difference of surface roughness has influence on surface color and translucency of dental composite resins. 〔J Kor Acad Cons Dent 31(4):312-322, 2006〕

Data on internode length obtained from cultural experiments on seeding date, seeding method and seeding rate in direct seeding cultivation of rice in 1989 were analyzed to investigate the rela-tionship between internode length and lodging. In general, internode length appeared to be longer in earlier plantings except May 11 planting which had longer internode than those of other plantings. Seeding in flooded condition as well as higher seeding rate resulted in longer internode length. Culm diameter leas greater in the order of April 21 > May 11 > May 21 > May 1 plantings, and drilled in upland condition > broadcasting in upland condition > seeding in flooded condition, while the higher the seeding rate, the greater the culm diameter was. Except seeding in upland condition and seething rate of 3kg/10a which showed lodging degree of 1, all other treatments resulted in severe lodging with degree of 7.
