This study was conducted to investigated the major characteristics of genetically modified rice of "Milyang 204" originated from Dongjinbyeo compared to a non-transgenic rice varieties Dongjinbyeo and Junambyeo. Basta resistant transgenic rice lines carrying bar gene produced by the Yeongnam Agricultural Research Institute were evaluated for their agronomic characters. The transgenic Japonica rice of "Milyang 204" showed inferior phenotypic traits compared to a non-transgenic rice variety Dongjinbyeo and Junambyeo. On the basis of UPOV (Union Internationale Pour la Protaection des Obtentions Vegetables) and NSMO(National Seed Management Office) the transgenic "Milyang 204" showed difference in some traits out of some agronomic traits, such as leaf color, angle of flag leaf, number of spikelets, culm length, white core and white belly compared to the nontransgenic varieties rice.

To design gene delivery systems which can deliver higher amounts of genes into stem cells, we studied the expression of receptors involved in the receptor-mediated endocytosis of bone marrow stromal stem cells. Bone marrow was isolated from ICR mice, and bone marrow stromal stem cells were isolated based on their plastic adherence property. Several cultrure conditions were screened for effective and continuous culture of marrow stromal stem cells. MesenCult medium was finally used to cultivate marrow stromal stem cells in vitro. As candidate receptors, various chemokine receptors were studied. Both bone marrow cells and marrow-derived stromal stem cells showed expression of CC chemokine receptors (CCR) and CXC chemokine receptors (CXCR). Marrow stromal stem cells showed higher expression of CCR5 and CXCR4 chemokine receptors as compared to other types of chemokine receptors. Moreover, though the expression chemokine receptors generally decreased in most chemokine receptors with the cultivation of marrow stromal stem cells, CCR5 and CXCR4 chemokine receptors retained the higher lever of receptor expressions over prolonged periods. These results suggest that the ligands exhibiting specific binding to CCR5 or CXCR4 might be used to modify gene delivery systems for increased level of receptor-mediated gene delivery into stromal stem cells.

이태리 문화유산의 생물손상

서정호,이향범 공주대학교 문화재보존과학연구소 2004 문화재과학기술 Vol.3 No.1

예술작품의 손상은 특히 많은 문화재를 보유한 이태리 같은 나라에서 커다란 문제가 되고 있다. 사실, UNESCO 보고에 따르면, 국제적으로 알려진 문화재의 2/3가 이태리에 있다고 한다. 고고학적 가치를 지닌 지역, 조각상, 건축물, 박물관, 교회와 유물, 지하 환경물 (동물 등)은 지정학적 위치, 오염수준, 인쇄물의 종류, 보존상태 등에 따라 다르지만 다양한 스트레스를 받기 쉽다. 이러한 모든 요인들이 다양한 양상의 생물적 공격에 영향을 끼친다. 석조물이 생물손상은 이태리 연구자들의 주요 관심분야 중의 하나이나 이외에도 서적, 유리, 목조 및 직물 등에서의 생물손상에 대해서도 관심을 보여 왔다. 이 연구의 재조사는 (i) 예술품의 생물손상에 영향을 주는 요소, (ii) 생물손상의 반응조직의 주요 범위, (iii) 연구자들이 진행하는 주요주제, 그리고 (iv) 이태리의 문화재 보존 생물손상 연구 분야 협회의 주요 업무를 파악하는 4가지 목적을 갖고 있다. The problem of deterioration of works of art is particularly relevant in countries like Italy that are rich in cultural heritage. In fact, following UNESCO data, in Italy are located 2/3 of the cultural heritage known in the world. Archeological areas, statues, buildings, museums, churches and items there located, hypogean environments, are subjected to different stresses due the geographical position, different degree of pollution, great variety of typology of materials and consequent status of conservation. All together these factors contribute to the different modality of biological attack. Biodeterioration can be defined as the irreversible loss of value and/or information of an object of art following the attack by living organisms. Biodeterioration of stone monuments is one of the principal field of interest of Italian researchers. However, other groups are also concerned with the biodeterioration of other materials as books, glass, wood textile and other materials. This review describes four main contents such as (i) factors affecting the biological deterioration of works of art, (ii) main groups of organisms responsible of biodeterioration, (iii) ongoing researches and main thematics, and (iv) main institutions and groups operating in the field of biodeterioration of cultural heritage in Italy.

We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.

나미향 김정하 정복희 청주대학교 학술연구소 2008 淸大學術論集 Vol.10 No.-

This study was made to investigate the real state of wearing briefs of females in their 20's to garner the basic data for pattern design and briefs whose wearing satisfaction is high. finding out the problem of design and sense of wearing. The result is as follows: 1. Cotton-made material was preferred in choosing briefs. This means that in the items concerning the sense of wearing, 'Sweat and secret were well absorbed, 'Sense of wearing was good', 'Material was proper,' 'Sense of wearing was generally fine.' 2. Half line was preferred in waist line, The reason is that it was conducive to action and stability. The result that currently-worn waist line and desired-waist line were in conformity shows that the satisfaction of currently-worn waist line was high in general. 3. For the reason that front form of briefs was good for action and stability, the form of half line was most preferred, and the same result was produced in the desired- wearing line. 4. In the form of hips, line 3 was preferred, which covered comfortably the entire parts of hips, and the styles which were jammed in hips, not sufficiently-covering hips, and uncomfortable to femoral muscle region were not preferred. 5. In purchasing briefs, the design was the first consideration, and then materials, measurement, price, etc. In the form of briefs, the type of pants was preferred, among which triangular pants accounted for 86.2% of preference, with most consumers fond of purchasing them. 6. The most preferred color was pastel tone, and white and ivory came after it. They are mostly sold in special market(road shop), and medium and low priced brand were preferred. key word : underwear, briefs, individuality expression, fashion item

매복된 상악 견치를 위한 외과적 수술을 동반하는 교정치료는 주위조직에 손상을 주지 않고 치열궁내에 적절히 위치시켜야 한다. 이를 위해 매복된 치아의 위치에 따라 다양한 외과적, 교정적 방법이 소개되었으며, 그 방법으로 window procedure, apically positioned flap, closed eruption technique, tunnel traction 등이 있다. 깊은 골연하 매복에서 사용할 수 있는 방법으로 closed eruption technique 그리고 tunnel traction이 있는데, closed eruption technique은 점막 및 치은 하방으로 지나는 견인 와이어의 자극으로 염증 발생 가능성이 높으며 치은퇴축 및 부착 치은의 소실이 발생할 수 있다. 하지만, tunnel traction은 치아의 맹출이 터널을 통해서 유도되어 각화치은에 둘러싸인 채 치조골의 중앙으로 나오게 되므로 치은퇴축이나 치주부착의 소실 없이 적절한 각화치은을 얻을 수 있으며 매복치가 치조골의 중심부로 맹출함에 따라 생리적 맹출과 같은 효과 얻을 수 있다. 본 증례는 깊은 매복을 보이는 상악 견치를 tunnel traction을 이용한 치료를 보고한 것으로, 적절한 방향을 가지고 맹출하였으며 치은퇴축이나 부착치은의 소실이 발생하지 않았다. The impacted maxillary canine is a common problem of which all dental practitioners should be aware. The surgical orthodontic treatment of impacted canines is replaced correction position in dental arch without periodontal damage. Many treatment possibilities have been considered for this goal; window procedure, apically positioned flap, closed eruption technique and tunnel traction. Prognosis for these treatment may be very uncertain in many case(infraosseous impacted tooth). Other steps are required to achieve a satisfactory periodontal outcome. Satisfactory results could be expected if the physiologic eruption pattern is restored by tunnel traction, because permanent tooth erupts through the gingiva near the crest of the ridge so that periodontal damage is reduced. This article report that the surgical orthodontic treatment using tunnel traction is obtained proper position and reduced periodontal damage in facially impacted maxillary canines.

Lipomyelomeningocele is the most common malformation leading to spinal cord tethering. Nonetheless, these lesion continues to pose a challenge in patient management. The purpose of this study was to identify the clinical feature, candidate for surgical repair, and outcome of lipomyelomeningocele in young children and adults. We studied the magnetic resonance images and/or lumbar myelo-CT of lipomyelomeningocele performed between January 1987 and September 1995 at our institutions and reviewed the pertinent medical records and radiologic studies to determine clinical feature, surgical candidate, and outcomes of these patients. Of the 14 cases(11 female and 3 males) studied, the most common factor that caused these patients to seek help was the cosmetic effect of the mass on their back, followed by urinary incontinence, and weakness of lower extremities. The patients' age ranged from 2 months to 21 years(mean, 5.0 years). All the patients underwent immediate surgical management that consisted of removal of lipoma, untethering of the cord, and complete dural sac repair. Follow up for these patients ranged from 6 to 82 months(median, 54 mo). None of the patients that underwent surgical correction before the emergence of neurological deficit had ever developed neurological deficits at the end of the follow up. However a few of the patients, despite presented with neurological deficits or urinary incontinence at the time of surgery, improved significantly. In conclusion, early detection and prophylactic surgery is imperative to prevent permanent neurological deficits and urinary dysfunction.
