Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

Tae‐Hoon Lee,Hee‐Young Yang,Joseph Kwon,Hoon‐In Choi,Lina Ren,Ung Yang,Byung‐Ju Park,Zae Young Ryoo 한국동물생명공학회(구 한국동물번식학회) 2011 발생공학 국제심포지엄 및 학술대회 Vol.2011 No.1

Peroxiredoxin V, an atypical thioredoxin peroxidase, is widely expressed in mammalian tissues. In addition, Prdx V is localized in mitochondria, peroxisome, cytosol, and nucleus. Prdx V has been reported to protect a wide range of cellular environments as antioxidant enzyme, and its dysfunctions may be implicated in several diseases, such as cancer, inflammation, and neurodegenerative disease. Identification and relative quantification of proteins affected by Prdx V may help identify novel signaling mechanisms that are important for oxidative stress response. However, the role of Prdx V in the modulation of hypoxia‐related cellular response is not studied yet. In order to examine the function of endogenous Prdx V in hypoxic condition in vivo, we generated a transgenic mouse model with Prdx V siRNA expression controlled by U6 promoter. Of many tissues, the knockdown of Prdx V expression was displayed in kidney, lung, and liver, but not spleen and skin. We conducted on the basis of nano‐UPLC‐MSE proteomic study to identify the Prdx V‐affected protein networks in hypoxic kidneys. In this study, we identified protein networks associated with oxidative stress, fatty acid metabolism, and mitochondrial dysfunction. Our results indicated that Prdx V affected to regulation of kidney homeostasis under hypoxia stress.

본 연구는 만 2~5세 영·유아의 발달 상태를 객관적으로 평가함과 동시에 발달이 지연된 영·유아를 선별할 수 있는 발달평가도구 문항을 개발하기 위한 예비연구이다. 이를 위해 문헌고찰 및 발달관련 평가도구들을 비교 분석하여 발달지표를 선정하고, 만 2세~5세까지의 영·유아의 언어, 인지, 사회·정서발달영역을 교사관찰에 기초하여 평가할 수 있는 문항을 개발하였다. 연구대상은 대도시, 중소도시, 읍면 소재지 별로 표집 된 만 2세부터 5세까지 총 13개 유아교육기관에 다니는 435명의 영·유아들이며, 본 연구에서 최종 개발된 평가도구의 문항은 총 141문항이다. 평가도구 문항은 언어, 인지, 사회·정서발달영역별로 영·유아의 행동과 언어를 중심으로 교사가 관찰하고, 관찰하기 어려운 문항에 대해서는 단서와 kit를 제시하여 평가할 수 있도록 구성하였다. 개발된 평가도구 문항의 적절성을 알아보기 위하여 내용 타당도와 내적 신뢰도를 살펴본 결과 비교적 양호한 것으로 나타났다. This was a preliminary study to construct a developmental rating scale for understanding children's objective developmental levels and screening developmental disabilities. For this purpose, a developmental indicator was selected by a literature review and comparative analysis of related developmental assessment tests. An assessment scale based on teacher's observations to measure language, recognition, and social-emotional developmental areas was developed. The subjects were 435 young children aged 2 to 5 who lived in both urban and rural areas. A trial test consisted of 141 assessment items in the language, recognition, and social-emotional developmental domains. The developmental scale was evaluated by teachers who observed children's behavior and language, and used clues and kits. Tests on validity and reliability for confirming the appropriateness of the developed assessment scale showed that content was relatively valid and internally consistent.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

본 연구는 21품종의 장미꽃에 대한 식품 및 화장품 원료로 사용 가능성을 살펴보기 위해 페놀성 화합물과 항산화 활성을 평가하였다. 총 폴리페놀, 총 플라보노이드 및 타닌 함량은 러버샤이 품종에서 각각 379.70 mg GAE/extract g, 50.10 mg CE/extract g 및 339.44 mg TAE/extract g으로 높게 나타났으며, 칠백리 품종에서 각각 107.25 mg GAE/extract g, 9.46 mg CE/extract g 및 36.31 mg TAE/extract g으로 낮았다. 페놀산 함량은 총 폴리페놀 함량과 유사한 결과를 보였으며, 러버샤이 품종에서 27.40 mg/extract g으로 높았다. 안토시아닌은 대부분 cyanidin-3,5-diglucoside로 확인되었으며 총 안토시아닌 함량은 유니나 품종에서 8.80 mg/extract g으로 가장 높았다. ABTS 및 DPPH 라디칼 소거 활성은 각각 428.10 및 419.59 mg AAE/extract g로 러버샤이 품종에서 가장 높았으며, 항산화 활성과 페놀 화합물의 함량과 높은 양의 상관관계를 보였다. 이러한 결과는 러버샤이와 같은 항산화 활성이 뛰어난 품종들이 관상 목적뿐만 아니라 높은 기능성을 가진 식품 및 화장품의 원료로 사용 가능성이 있다고 판단된다. This study evaluated the functional components and antioxidant activities of 21 different rose flower extracts, to confirm their value as a food and cosmetics ingredient. The highest values of total polyphenol, flavonoid and tannin contents (379.70±1.64 mg GAE/extract g, 50.10±0.76 mg CE/extract g, and 339.44±1.20 mg TAE/extract g, respectively) were obtained in Lover Shy. The proanthocyanidin content ranged from 61.88 mg CE/extract g in the Unina cultivar to 5.34±0.13 mg CE/extract g in the Aileen cultivar. The phenolic acid content obtained was highest in the Lover Shy cultivar (27.40±0.26 mg/extract g), whereas highest levels of anthocyanin (8.83±0.03 mg/extract g) were obtained in the Unina cultivar. High ABTS and DPPH radical scavenging activities were determined in the Lover Shy cultivar (428.10±0.29 and 419.59±3.12 mg AAE/extract g, respectively). Taken together, these results indicate that the antioxidant activity and functional components of Lover Shy cultivar are superior, and this extract can potentially be applied as a food and cosmetic ingredient.

Elementary schools are one of the important public facilities as the basis of student out-door activities as well as residential community activities in a region. Thus, the location of elementary schools must be closely related to student out-door facilities: playgrounds within schools, playgrounds in apartment complexes near schools, and community playgrounds in the region. In view of urban planning, the student out-door facilities must be planned and built as a key residential component by regulations of community site planning. However, the location of elementary schools is not associated with that of student out-door facilities in many cities because elementary schools and student out-door facilities are not planned by same institutions with same target years and objectives. Seoul, the capital of Korea, is a very dynamic city in terms of population, educational facilities, and public facilities. The population of Seoul was at the highest point of 10,969,862 in year 1992, and has slowly decreased to 10,280,523 in year 2002. The number of elementary schools in Seoul has increased from 481 to 542 during the same period. Seoul is a very dense city with the area of 605.52㎢ and the population density of 16,978 person to a square kilometer. Thus, the playgrounds for elementary school students are always lack in terms of number and size, though the number of elementary schools is increasing in Seoul. The objectives of this research are (1) to investigate elementary school students in order to evaluate a change of educational environment, (2) to identify the association between the location of elementary schools and playgrounds for out-door activities of elementary school students in Seoul, and (3) to evaluate the impacts of three types of outdoor facilities elementary school playgrounds, playgrounds , and community playgrounds. To do this, this research uses various statistical analysis methods. The elementary school data sets are obtained from Seoul statistical books and educational public service books, GIS.

Jacob Burckhardt is not a particularly easy figure to situate within the historiography or the cultural history of the nineteenth century. He was influenced by a wide range of people whose work reflected a variety of cultural traditions, trends and circumstances. How then does one define his position within nineteenth century cultural history? While Burckhardt saw the beginnings of modernity in the history of Renaissance Italy, its climax or crisis point was reached during the French Revolution. Here once and for all, the individual was cut off from the past and all restorations were more or less made futile. It was not just that traditional institutions and inherited world views were destroyed. For Burckhardt the crisis ran much deeper. The dynamic but ultimately harmonious relationship between the subject and the object which had characterized Renaissance genius had been destroyed. replaced during the French Revolution by a new stance toward reality, the modem objective Bewuβtsein. perhaps more than any other cultural artifact, the genre of historical painting best articulated the aesthetic preferences of the desire to express great historical moments, as well as its openly didactic politicization, realism had found its most potent form of expression. However, according to Burckhardt at least, the overwhelming passion for realism was made at a cost; in its name idealism was sacrificed, and the harmony which characterized the truly sublime spirit of individual creativity was lost. He thought a ideal historian to have sensitivity and imagination for understanding what was its true mature. Burckhadt's historical study connected with not history for study but history for education of the public. Needless to say, his aim was not the public made meet the needs of the times but their lost sensitivities and imaginations in the process of industrialization inspired them again. So his lecture continued in Pedagogium, and he thought that a study of high-class culture was the proper of preserving humanistic culture.

본 실험은 고추의 형질전환체 선발을 위한 최소의 항생제농도를 결정하고 그 결과를 이용하여 형질전환체를 유기하고 효율을 최대화하기 위하여 수행한 바 그 결과는 다음과 같다. 1. 항생제 감응성 검정결과 kanamycin 40㎎/ℓ와 hygromycin 20 ㎎/ℓ에서 신초형성이 완전히 억제되었다. 2. Agrobacterium 제거에 사용되는 carbenicillin과 cefotaxime 처리시 재분화에 아무런 영향을 미치지 않았으며 cefotaxime 200㎎/ℓ 처리에서는 무처리구보다 신초형성이 더 활발하였다. 3. 회복친인 135Q와 276F에서는 형질 전환시 높은 재분화율을 보였으나 형질전환율은 각각 10%와 11.1%의 낮은 빈도를 보였다. 4. 재분화된 신초들을 대상으로 histochemical GUS assay를 실시한 결과 부분적으로 푸른발색이 확인되었다. 5. GUS활성을 보인 신초들에 대한 NPTⅡprimer를 이용한 PCR검정에서 NPTⅡ 유전자의 존재가 확인되었다. A transformation system using Agrobacterium tumefaciens was developed with different genotypes of hot peppers (Capsicum annuum). Four antibiotics commonly used in Agrobacterium-mediated transformation were tested for their effects on shoot regeneration. Shoot induction was completely inhibited by kanamycin at 40㎎/ℓ and hygromycin at 20㎎/ℓ or higher, but not by carbenicillin and cefotaxime. Cotyledon explants of hot peppers were cocultivated with Agrobacterium turnefaciens LBA4404 which carries a binary. vector pBI121 harboring the neomycin phosphotransferase, type Ⅱ (NPT Ⅱ) gene and β-glucuronidase (GUS) gene. For selection of transformed cells, 40㎎/ℓ kanamycin were used because the sensitivity test showed that 40㎎/ℓ kanamycin completely inhibited shoot induction from nontransformed cells. Histochemical GUS assay showed the presence of the GUS gene and PCR analysis confirmed the NP TⅡ gene was integrated. Transformation frequency was about 10.0% and 11.1% of total regenerants from 135Q and 276F, respectively.
