두 변화검출 마스크를 이용한 3차원 영상분할 초저속 동영상 부호화
이상미,김남철,손현,Lee, Sang-Mi,Kim, Nam-Chul,Son, Hyon 대한전자공학회 1990 전자공학회논문지 Vol.27 No.10
A new 3-D segmentation-based coding technique is proposed for transmitting the motion video with reasonablly acceptable quality even at a very low bit rate. Only meaningful motion areas are extracted by using two change detection masks and a current frame is directly segmented rather than a difference frame itself so that a good quality of image can be obtained at high compression ratios. Through the experiments, the sequence of Miss America is reconstructed with visually acceptable quality at the very high compression ratio of 360:1. 아주 높은 압축률에서도 시각적으로 만족할 만한 동영상을 전송할 수 있는 3차원 영상 분할기반 부호화법을 제안하였다. 두개의 변화검출 마스크를 이용하여 동영상에서 의미있는 움직임 영역만을 효과적으로 추출하고 또한, 차영상을 분할하는 대신 현재 프레임을 직접 분할함으로써 높은 압축률에서도 우수한 품질의 영상을 얻을 수 있다. 실험을 통해, 제안된 방법은 Miss America의 연속영상을 360배 정도의 압축률로 전송하였을 경우에도 재생영상의 품질이 우수함을 확인하였다.

돼지 $\beta$-Casein을 이용한 EGFP 발현 Knock-in 벡터의 구축 및 발현 검증
이상미,김혜민,문승주,강만종,Lee, Sang-Mi,Kim, Hey-Min,Moon, Seung-Ju,Kang, Man-Jong 한국동물번식학회 2008 Reproductive & developmental biology Vol.32 No.3
This study was carried out to develop knock-in vector for EGFP (enhanced green fluorescent protein) expression in porcine $\beta$-casein locus. For construction of knock-in vector using porcine $\beta$-casein gene, we cloned the $\beta$-casein genome DNA from porcine fetal fibroblast cells, EGFP and SV40 polyA signal using PCR. The knock-in vectors consisted of a 5-kb fragment as the 5' recombination arm and a 2.7-kb fragment as the 3' recombination arm. We used the neomycin resistance gene ($neo^{r}$) as a positive selectable marker and the diphtheria toxin A (DT-A) gene as a negative selectable marker. To demonstrate EGFP expression from knock-in vector, we are transfected knock-in vector that has EGFP gene in murine mammary epithelial cell line HC11 cells with pSV2 neo plasmid. The EGFP expression was detected in HC11 cells transfected knock-in vector. This result demonstrates that this knock-in vector may be used for the development of knock-in transgenic pig. 본 연구는 돼지 $\beta$-casein 유전자 위치에서 EGFP가 발현될 수 있는 knock-in 벡터를 구축하기 위하여 실시되었다. 돼지의 $\beta$-casein 유전자를 이용하여 knock-in 벡터를 구축하기 위해 돼지의 태아 섬유아세포로부터 $\beta$-casein 유전자를 동정하였고 EGFP, SV4O polyA signal을 동정하였다. Knock-in 벡터는 5' 상동 영역 약 5 kb와 3' 상동 영역 약 2.7 kb로 구성되어있으며, positive selection marker로 $neo^{r}$ 유전자를, negative selection marker로 DT-A 유전자를 사용하였다. 구축된 knock-in 벡터로부터 EGFP의 발현을 확인하기 위하여 생쥐 유선 세포인 HC11 세포에 knock-in 벡터를 도입하였다. 그 결과 EGFP의 발현을 HC11 세포에서 확인하였다. 이와 같은 결과로서 이 block-in 벡터는 knock-in 형질전환 돼지를 생산하는데 사용될 수 있을 것으로 생각된다.

해계 유침과 전침이 loperamide로 저하된 흰 쥐의 장운동에 미치는 영향
이상미,이현,Lee, Sang-Mi,Lee, Hyun 대한약침학회 2009 Journal of pharmacopuncture Vol.12 No.4
Objectives : The purpose of this study was to compare the effect of acpuncture and electro-acupuncture of low(EA(L)) and high(EA(H)) frequency at Haegye(ST41) on intestinal hypomotility induced with loperamide in rats. Methods : We made suppressed state of intestinal motility with loperamide in rats and carried out needle retention acupuncture, low frequency electro-acupuncture and high frequency electro-acupuncture at ST41 in rats devided into pre-treatment group and post-treatment group. We fed charcoal to them after the treatment and measured the travel rate of charcoal in the gastrointestinal track to analyze which treatment is more effective in state of intestinal hypomotility. Results : None of acupuncture, EA(L) and EA(H) at ST41 had significant influences on intestinal motility of rat in normal state. Needle retention at ST41 did not significantly increase intestinal motility suppressed with loperamide in rats. Pre-treatment of EA(L) and EA(H) at ST41 significantly increased intestinal motility suppressed with loperamide in rats. Post-treatment of EA(L) and EA(H) at ST41 did not have significant influences on intestinal motility of rat in normal state. Conclusions : These results suggest that treatment of EA(L) and EA(H) at ST41 may be effective on gastric disorders such as intestinal hypomotility and its effect had more prevention than cure. Further study is necessary to know more effects of ST41 and electro-acupuncture of low and high frequency.

기능적 시력장애로 의심되었던 환아들에서 시행한 아동행동평가척도와 인성검사
이상미,임명호,경성은.Sang Mi Lee. MD. Myung Ho Lim. MD. Sung Eun Kyung. MD. PhD 대한안과학회 2010 대한안과학회지 Vol.51 No.8
Purpose: To investigate the clinical courses of children with functional visual loss and to evaluate their psychosocial problems. Methods: Thirteen children who visited the ophthalmic clinic of Dankook University Hospital because of functional vision loss between August 1, 2005 and January 1, 2009 were examined to establish the cause of lost vision. The results of the child behavior checklist-Korean version (K-CBCL) and the Korean personality inventory for children (KPI-C) were obtained in nine out of the 13 children. Results: The mean visual acuities at the initial and last visits for nine children in the functional visual loss group were 0.58 ± 0.28 and 0.89 ± 0.31, respectively. Somatic complaints, social problems and overall behavioral problems were statistically significantly different from those of the control group according to the K-CBCL, and somatic concern was statistically significantly different from that of the control group according to the KPI-C. Conclusions: Children in the functional visual loss group had different traits from those in the control group according to the K-CBCL and KPI-C. Children's psychosocial problems could be expressed as somatic symptoms, of which vision loss should be considered a major factor. J Korean Ophthalmol Soc 2010;51(8):1092-1098

문양은 오래전부터 상징적, 장식적, 주술적 의미를 지니며 언제 어디서나 존재해 왔다. 끊임없이 변화하는 역사, 문화, 사회 등을 반영하며 함께 변화하였고 개발된 문양은 다양한 사물에 적용되어 상품화 되었다. 반면 돌의 문양은 현재까지 살펴보면 선의 단순화를 통한 괴석문을 제외하면 돌 표면의 사실적 문양을 사용하거나 쌓는 방식에 의해 나타나는 문양으로 크게 2가지 방향으로 사용되고 있다. 제주의 디자인상품개발을 위한 다양한 현무암의 문양을 개발하기 위해서 현재까지 사용된 돌 문양을 조사 및 분석 하여 돌 문양의 분류체계를 정의하고 기연구된 논문을 통해 문양 개발의 프로세스를 기초문양개발과 확장된 형태인 응용문양개발로 2단계화 시켰으며 이를 바탕으로 현무암을 사실적, 양식적, 추상적 문양으로 개발하고 이를 적용한 디자인상품을 제안하였다. 이로써 현무암문양의 다양한 개발은 현무암 자체로써만 상품화가 되는 것이 아니라 문양의 개발과 적용으로써 지역특색을 지니는 디자인상품으로써 색다르고 다양한 개발방법에 많은 방향을 제시할 수 있을 것이다. Having a symbolic, decorative, magical significance, Patterns have been existed anywhere for a long time. Constantly being be affected by history, culture, society, the pattern are having developed and changed, and then it have been applied to various things commercially. But if we research the pattern of stone, It`s pattern has been used two directions, except for the unusual rock that used simple lines. one is to use an exact realistic surface pattern of stone, the other is to use stacking method. In order to develop a variety of Basalt patterns for Jeju`s souvenir, we have to define the classification scheme with a research and analysis of stone. the method of pattern design can be organized into two ways. one way is to make a basic pattern, the other is to make a expanded pattern. these two way could be applied to the development and product of this stone patterns. Through the development of a various patterns of Jeju basalt, the Souvenir of jeju can be presented a variety of ways.

This thesis is a study on the Zen poem by Mooeuija, Hyesim which represents Korean Zen poem. In this thesis, this researcher tried to widen the width of understanding for Korean Zen poem by studying his Zen poem concretely around the poem which chanted the state of miraculousness of mind that he realized in the dimension of Zen which seeks wisdom from above through paying attention to the point that Mooeuija is a full-scale Zen poet who led the rise of Zen at the period of Koryo when military subjects took power. To classify the world of Zen poem by Mooeuija in terms of contents in accordance with the state of miraculousness of mind is to classify into the poem which made the state contemplated by entering into Zen state or ecstasy, the poem which made the state to forget inside mind and outside state into form, and the poem which made the free state to be based on innocence into form. First, in the poem which made the state contemplated by entering into Zen state of ecstasy into form, the implication outside language was<br/> expressed richly and the poetic inside was expressed solidly by making the meaning of Zen into form through diverse rhetorics, without expressing the meaning of Zen with poem directly by using Zen language to explain the principle of real state of the miraculousness of mind which reaches intuition while thinking is silent by entering into Zen. Second, in the poem which made the state to forget inside mind and outside state into form, the state of miraeulousness of mind which reveals truth brightly through whole body as he forgets in side mind and outside state was made into form naturally, with the state that thing<br/> and I are consistent completely in which reason and thing harmonize in accordance with time karma.<br/> Third, in the poem which made free state into form because of innocence, he chanted the leisure sentiment that he felt spontaneously<br/> in the state of innocence, in the new state of nature. Besides, he made the innocent state into form as t he state to keep his place comfortably<br/> in accordance with karma concretely. Then, especially, he showed the state that poem and Zen are one in which mind state and poetic state<br/> harmonize naturally by comparing the state of self-sufficient poet to simple water pepper flower.<br/> From this viewpoint, the Zen poem of Mooeuija may be evaluated highly by the fact that it cultivated the metaphysical poem to be first in the history of Korean Chinese poetry by showing the state that poem and Zen are one realistically through sublimating the state of miraculousness of mind into the state of art.<br/> <br/> <br/>
