Background: The etiopathogenesis of late preterm (LPT) birth is undetermined. Placental histopathology, which reflects an adverse intrauterine environment and is reportedly associated with preterm labor and neonatal morbidities, has not been studied in LPT infants. Purpose: We investigated placental pathological lesion as markers of an adverse intrauterine environment during LPT labor. Methods: This retrospective case-control study compared placental histopathological and clinical variables between LPT and term neonates. Placental variables included chorioamnionitis, funisitis, hemorrhage, abruption, infarction, calcification, and syncytial knots. Maternal variables included age, substance abuse, pregnancyassociated diabetes mellitus and hypertension, duration of rupture of membrane, antibiotic use, and magnesium sulfate, whereas, those of neonates included gestational age, birth weight, race, sex, and Apgar scores. Standard statistical proedures were applied to analyze the data. Results: Chorioamnionitis (50% vs. 17.8%, P<0.001) and funisitis (20% vs. 4.4%, P=0.002) were more common in term infants. Placental infarction rate was insignificantly higher in LPT infants (25.6% vs. 14.3%, P=0.08). The mothers in the LPT group were older (30.4 years vs. 28.1 years, P=0.05; odds ratio [OR], 1.06; 95% confidence interval [CI], 0.998-1.12, P=0.056) and more often suffered from hypertension (28.9 vs. 12.9 %, P=0.02), and received magnesium sulfate (48.9 vs. 20%, P< 0.001; OR, 2.86; 95% CI, 1.12-7.29, P<0.05). Duration of rupture of membrane was higher in term infants (13.6 hours vs. 9.1 hours, P<0.001). Chorioamnionitis (OR, 0.33; 95% CI, 0.13-0.79; P<0.05) was associated with a lower risk of LPT delivery. Conclusion: Placental infection is not a risk factor for LPT births. There is a nonsignificant predominance of vascular anomalies in LPT placentas. Higher maternal age, magnesium sulfate therapy, and maternal hypertension are clinical risk factors for LPT labor.

The unicellular green alga Dunaliella salina is a halotolerant eukaryotic organism. Its halophytic properties provide an important advantage for open pond mass cultivation, since D. salina can be grown selectively. D. salina was originally described by E. C. Teodoresco in 1905. Since that time, numerous isolates of D. salina have been identified from hypersaline environments on different continents. The new Dunaliella strain used for this study was isolated from the salt farm area of the west coastal side of South Korea. Cells of the new strain were approximately oval- or pear-shaped (approximately $16-24\;{\mu}m$ long and $10-15\;{\mu}m$ wide), and contained one pyrenoid, cytoplasmatic granules, and no visible eyespot. Although levels of $\beta$-carotene per cell were relatively low in cells grown at salinities between 0.5 to 2.5 M NaCl, cells grown at 4.5 M NaCl contained about a ten-fold increase in cellular levels of $\beta$-carotene, which demonstrated that cells of the new Korean strain of Dunaliella can overaccumulate $\beta$-carotene in response to salt stress. Analysis of the ITS1 and ITS2 regions of the new Korean isolate showed that it is in the same clade as D. salina. Consequently, based on comparative cell morphology, biochemistry, and molecular phylogeny, the new Dunaliella isolate from South Korea was classified as D. salina KCTC10654BP.

국내 주요 대도시는 도심지 내 고비용의 지가와 개발가능부지의 부족으로 기존 대규모 택지공급방식에 대한 대안의 필요성에 직면하고 있다. 또한 높은 주택수요와 부족한 공급량에 대한 대응으로 적정가격의 주택을 공급하고 관련 주택기관의 재정적 안정성을 동시에 고민하고 있다. 특히 공공부문은 최근 획일적 공공임대주택의 공급에서 탈피하여 소득 및 수요계층에 부합하는 다양한 형태의 임대주택 공급을 시도하고 있다. 본 연구가 주목하는 NYCHA(New York City Housing Authority) 인필개발(Infill Development)은 뉴욕시의 거시적인 주거정책인 "Next Generation NYCHA"에 포함된 세부 실행사업이며 이러한 국내 상황과 동일한 맥락적 상황에 대한 대응이다. 이는 공공부문의 주도적 역할을 통해 기존 문제적 공공주택단지의 유휴부지 개발을 통하여 주택공급량을 확대함으로 서민을 위한 주거저렴성 확보와 동시에 만성적 적자에 허덕이는 뉴욕시 주택공사의 재정상태 강화를 목적으로 한다. 나아가 이 사업을 통해 주변지역으로 부터 고립되어 다양한 사회-경제적 문제점이 노출되는 공공주택단지에 대한 해결방안을 함께 모색한다. 이에 본 연구는 현재 뉴욕시에서 추진 중인 관련 개발사례에 대한 진행과정, 다양한 비평, 세부적 내용을 분석함을 통해 국내에 참조가능한 시사점을 도출하고, 나아가 국내 공공주택 공급확대를 위한 다양한 사업방식의 개발에 일조하고자 한다.

본 연구는 미국 뉴욕시 브루클린에 위치한 퍼시픽 파크(구 아틀란틱 야드)개발의 진행과정에 대한 분석을 목적으로 한다. 퍼시픽 파크는 맨해튼의 허드슨 야드 개발과 함께 철도상부 공중권 개발로 세계적인 주목을 받는 뉴욕시의 대표적 대규모 도시개발사업이다. 과거의 대규모 개발사업의 부활과 동시에 그 진보된 형태를 보여주어 큰 사회적 관심을 받았다. 특히 개발은 지역주민과 협력하여 혜택을 나누는 지역혜택협약을 활용한 모범적인 개발로 평가받았다. 그러나 안타깝게도 현재 다양한 어려움으로 인해 사업초기 목적한 완공시기와 사업내용에서 벗어나 힘겹게 진행되고 있음으로 사회적 우려와 비판을 야기하고 있다. 이에 본 연구는 이 개발과정을 심도있게 살펴봄으로 위기유발 요인 및 대응을 위해 시도된 다양한 개발사업자와 공공부문의 대응을 중심으로 본 사업을 고찰한다. 이를 위해 본 연구는 다음과 같이 구성된다. 제2장에서 미국 도시재개발사업 대한 이론적 배경에 대해 살펴보고, 제3장에서는 연구대상 사업에 대한 구체적인 변화과정과 사업내용의 주요사항을 분석하고, 제4장은 개발과정상의 변화와 대응을 중심으로 다음의 시사점을 도출하였다. 1)개발사업자의 유연성 확보 및 강제성 부여, 2)개발부지에 대한 종합적 제어, 3)공공과의 소통 및 대응 방식, 4)추가 사업재원의 확보 방식, 5)기술부문의 신중한 검증

For the purpose of this Study, the situation of Korean costume properties in the collection of overseas museums was investigated through correspondence, interviews with their curators and persons in charge and survey. As results were made about the situation of museum science (conservation) and practical utilization of costume properties. So, the study result were drawn as follows : Krean costume properties unexplaind of 'Korean cultural Properties' could be found in the Metropolitan Museum of Art of New York(135 pieces), the Brooklyn Museum of New York(20 pieces), the Newark Museum of New Jersey(15 pieces), and the Victoria Albert Museum of London(100 pieces). Korean costume properties in the collection of over-seas museums mostly fall under the rang of period between the 19th century and the early 20th century and are classified into everyday clothing, wedding costume and armors for the most part. In 1900s, museum in several countries began to collected Korean cultural properties through foreign missionaries or diplomats as well as merchants or travellers in who bought Korean objects. Recently, scholars, traditional Korean costume designerss and diplomatic and consular offices in overseas have donated our Korean costume to many foreign museums. Korean costume properties were largely on display in the dependent display of folklore museums or in a part of exhibition gallery for Asian culture and there were the separate exhibition rooms in museums in the United Kingdom, Germany, Denmark, Austria, Japan and the United States America. But the size and level of display room for Korean cultural properties is one third as large as that for chinese or Japanese cultual properties. It was found in this study that the traditional Korean costume in the collection of overseas museums was largely recorded only as general items rather than given their proper names. The typical example of misnaming included bridal's Kimono for Wonsam(원삼) in the Metropolitan Museum of Art, Yeonroksaek-bumunsajeokori for Dangeui(당의) and Jissan-gryongwonmunsadurumagi for Kongdali(동달이) in the Okura collection of the Tokyo National Museum, and so on. And the Victoria Albert Museum modified the way of wearing Daenim(대님) and the National Museum of Ethnology in Osaka seemed to misplace the ornament of Keanggi(댕기) on Mubok(무복) and Josunjuk(조선족: Chinese-Korean) Museum also misplace hansam(한삼). On the one hand, the Newark museum of New Jersey mixed Chinese armor with the Korean one and the Photohraph of King Kojong(고종) with Chinese one. It is corrected to publish and disseminate the book concering Korean costume in order to inform foreign museums of thed proper names and wearing method of our traditional costumed. The repair of costume before cleaning in the process of conservation treatment can prevent damage likely to occur as the properties of fiber itself are weakened in liquid. It is recommended that western 8-figure stitch and tacking stitch is added to Korean traditional stitching method. Museums in the U.S.A and the U.K are concerned about the aftermath of cleaning it-self, specially conservation treatment may exert on remains and predominantly use the vacuuming method to remove dust or bits of straw before the exhibition beings. But in case of Korea, the dry cleaning and wet cleaning method are used according to the nature and state of a sample costume. This comprehensive cleaning method is gradually developing scientifically but it is expected that those concerned will make a chemical analysis of the solvent to be used and also the more precise test of costume properties will be conducted before cleaning them. A partial study was made here because the scope of study was too broad and vast. It is expected that more studies will be conducted concerning our costume culture under the long-term plan and active support at the government level.
