Purpose: Retinal neovascularization in diabetes has been thought to follow the release of local angiogenic factors in the retina. We hypothesized that neovascularization of diabetic retinopathy is a systemic vasculogenesis rather than a local angiogenesis. Thus, we evaluated the concentrations of circulating endothelial progenitor cells (EPCs) and stem cell modulation factors such as vascular endothelial growth factor (VEGF), erythropoietin (EPO), and substance p (SP) in the peripheral blood of diabetic retinopathy patients. Methods: We studied 15 normal controls and 45 Type 2 diabetic patients [non-DR group (n=15), NPDR group (n=15), and PDR group (n=15)]. We measured circulating CD34+mononuclear cells (CD34+MNCs) and c-Kit+ mononuclear cells (c-Kit+MNCs) by flow cytometry. VEGF, EPO and SP in the peripheral blood were measured by ELISA. Results: The circulating CD34+MNCs and c-Kit+MNCs increased in the NPDR and PDR groups compared with the control group (P<0.01). The serum level of VEGF was increased in the NPDR and PDR groups compared with the control group (P<0.05). The level of EPO was exclusively elevated in the non-DR group compared with the other three groups (P<0.01). The circulating SP level increased in the NPDR and PDR groups compared with the control group (P<0.05). Conclusions: The present study is the first to demonstrate that CD34+MNCs, c-Kit+MNCs and their modulator are elevated in diabetic retinopathy patients. Therefore, it is possible that circulating EPCs and serum VEGF, EPO and SP may be involved in the progression of diabetic retinopathy.

이봉호,이인걸,Bong-Ho Lee,In-Gul Lee 한국작물학회 1976 Korean journal of crop science Vol.21 No.1

맥주맥의 육종에 있어서 곡립형질의 효율적인 선발자료를 얻고자 2조대맥 10품종을 공시하여 곡립형질의 유전력, 유전적 획득량, 상관관계, 경로계수등을 통계 유전학적으로 분석한 결과를 요약하면 다음과 같다. 1. 곡립형질들 중에서 곡피 (H=0.886), 분상질(H=0.848), 곡립형성비수(H=0.823)등은 유전력이 높고, 수량(H=0.526), 곡립폭(H=0.420)등은 유전역이 비교적 낮았다. 2. 기특되는 선발효율은 곡피(52.7%), 분상질(31.8%), 선입률(23.0%), 등이 높고, 곡립장(6.2%), 곡립폭(3.7%), 곡립후(8.7%) 등이 낮았다. 3. 맥주의 품질을 위하여 선발의 대상이되는 실용형질중 천립중, 분상질 Protein간의 상관관계는 다소유의성이 있었으나 곡립형질과 수량간의 상관관계는 유의성이 없었다. 4. 천립중, 곡피 및 수량의 선발은 이들에 대하여 직접효과가 큰 곡립후를 이용하여 간접적으로 선발하는 것이 효율적인 것으로 보였다. 5. 분상질 및 Protein을 위한 선발은 곡립후, 곡피 등과 수량간의 부의 간접효과를 개선하고 수량의 직접효과를 향상시키는 것이 유리할 것으로 보였다. This study was carried out to attain the selection information on grain characters of malting barley. Indirect selection, making use of information on grain thickness, seemed to be an effective method for the selection of 1, 000 grain weight, grain hull and grain yield which were directly affected by grain thickness. Grain yield which had a direct effect on grain, meal and protein content seemed to be an effective selection indicator for them, however, a better method is expected upon improvement of indirect effects of hull and grain yield.

디지털기술의 발달로 휴대폰이 필수품이 되었고 언제 어디서나 메신저의 채팅창을 통해 끊임없는 대화를 나누며 텔레비전 속에서 세상 온갖 문물을 만나볼 수 있는 디지털문명시대 속에 우리는 살아가고 있다. 하지만 사람들은 기술의 발전이 주는 문명의 이기 속에서 오히려 변화에 소외될 것을 두려워하며 시대의 급박한 흐름에 휩쓸려 경제 불황의 늪에서 허덕이고 있다. 이러한 불안과 불황의 분위기를 돌파하기 위해 최첨단의 기술 속에서 인간다움을 찾고, 차가운 라인들을 통해 서로 따뜻함을 교류하는 아이러니를 연출하고 있다. 이런 상황은 사회상을 대변하는 영상매체 속에서도 나타나고 있다. 현재 제작되고 있는 대부분의 3D 애니메이션 작품들이 기존의 차갑고 사실을 표방한 이질적 기법에서 벗어나 2.5D(3D의 카툰화)기법을 통해 따뜻한 분위기와 인간다움을 담은 라인 애니메이션으로 변화하고 있다. 본 논문은 3D CG가 가진 다양한 공간구성의 가능, 광범위한 크리에이티브의 표출, 지속적 사용 가능성 등의 장점에 덧붙여 따뜻하고 인간다운 휴머니티를 찾는 사회분위기에 발맞춰 라인 애니메이션을 활용한 TV-CM에 대해 분석해보고 앞으로의 발전가능성에 대해 논의해보고자 한다. We are living in the digital era that celluar phone became a must-have item, on-going conversation through the internet chatting program is available to us anytime anywhere and TV allows us to meet all the kinds of culture over the world. In other words, we live in the period of digital civilization. However, people are afraid of getting behind changes under a modern convenience resulted from the advancement of technology and struggled with an economic depression due to the rapid current of the times. It is a gloomy turn of the digital period. To find a way out of the fear and depression, people ironically try to find human nature in the state-of-the-art technologies and interchange heart-warming mind with cold liens. The ironical situation is also found in video media representative of a mirror of society. Currently, most 3D animation works pursue not the existing heterogeneous technique expressing cold-hearted and actual aspects but 2.5D (cartoonization of 3D) technique, which allows expression of warn-hearted mood and human nature with line animation. This study is to describe various advantages of 3D CG including formation of various space structures, wide expression of creativity and continuous availability analyze TV-CMs using line animation on the basis of the social mood pursuing warm-hearted and human nature, and discuss its development potential in future.

Experiment on the effects of vinyl mulching and chemical controller maleic acid hydrazide to Turkish tobacco variety Samsun-Maden were conducted at the Taegu Tobacco Experiment Station during the 1972. The concentration of M. H. was 0.5 per cent solution at the rate of 15ml per plant and the numbers of M. H. treated times were divided into control and from once to trice at intervals of eight days before flowering date. The results may be briefly summarized as follows: 1. Vinyl mulching had an effect to promote the early plant growth compare with nonmulching, and the reverse was the case in late plant growth. 2. There was a trend to decrease significantly the percentage of dry-up leaves with increase in the numbers of M. H. treated times and increase the percentage in the vinyl mulching blocks compare with non-mulching. 3. Total dry weight of each treatment appeared no significant differences from others, but the increases in dry weight of leaves from once or additional treatment of M. H. showed significant differences and the reverse was the case of roots and tops. 4. The maturing of leaves were promoted significantly by the treatment of vinyl mulching or M. H., and it also proved that the effect of additional treatment of M. H. 5. Yields were increased significantly with increase in the numbers of M. H. treated times, but not appeared the significant difference in quality. 6. Total alkaloid was decreased and the reverse was the case of total sugar in the sun-cured leaves by the treatment of vinyl mulching. When the M. H. was treated only once total alkaloid and sugar in the sun-cured leaves were increased compare with control, but decreased gradually with additional treatment.
