By the year 2050, the world population is set to increase to 9 billion people, of which 66% will be living in cities. It is argued that this will inevitably lead to further urban densification and soaring, inhumane and dense vertical environments. However, innovative and disruptive technologies impacting all realms of life means that we will also live, work, play, learn and make in novel ways, the beginnings of which are already becoming evident. These present opportunities for reimagining city environments, and in particular tall buildings, with a focus on reducing redundancies and re-appropriating existing buildings, creating novel hybrid environments, incorporating green and social democratic spaces, and integrating multiple modes of transport. This paper examines how vertical cities may perhaps be dense, resource efficient, and yet humane, presenting three possible scenarios for Singapore's context, which are, however, common to many Asian high-density urban environments. The scenarios presented are the outcome of Final-Year Thesis Projects undertaken by final-year architecture students at the National University of Singapore (NUS) in 2017.

Photoreaction of guest organic anions in layered organic-inorganic hybrid materials was investigated. The layered hybrids were synthesized by an anion-exchange reaction of $[LiAl_2(OH)_6]Cl{\cdot}yH_2O$ layered double hydroxide with aqueous (Z,Z)- and (E,E)-muconates under inert atmospheric condition, to give new organicinorganic hybrids of $[LiAl_2(OH)_6]_2[(Z,Z)-C_6H_4O_4]{\cdot}zH_2O$ and $[LiAl_2(OH)_6]_2[(E,E)-C_6H_4O_4]{\cdot}H_2O$, respectively. The basal spacings calculated by XRPD of intercalates indicate that muconate anions have almost vertical arrangements against the host $[LiAl_2(OH)_6]^+$ lattices in the interlayer of organic-inorganic hybrid materials. When UV light was irradiated on the suspension of $[LiAl_2(OH)_6]_2[(Z,Z)-C_6H_4O_4]{\cdot}zH_2O$, the (Z,Z)-muconate anions of the gallery space of hybrids were polymerized in the aqueous media while it was isomerized into more stable (E,E)-muconate in the methanollic suspension in the presence of catalytic amount of molecular iodine. All the products were characterized using elemental analysis, TGA, XRPD, FT-IR, $^1H$ NMR and $^{13}C$ CP-MAS NMR.

To identify unintended vertical gene-transfer rates from the developed transgenic plants, rapid and unequivocal techniques are needed to identify event-specific markers based on flanking sequences around the transgene and to distinguish zygosity such as homo- and hetero-zygosity. To facilitate evaluation of zygosity, a polymerase chain reaction technique was used to analyze a transgenic pepper line B20 (homozygote), P915 wild type (null zygote), and their F1 hybrids, which were used as transgene contaminated plants. First, we sequenced the 3'-flanking region of the T-DNA (1,277 bp) in the transgenic pepper event B20. Based on sequence information for the 3'- and 5'-flanking region of T-DNA provided in a previous study, a primer pair was designed to amplify full length T-DNA in B20. We successfully amplified the full length T-DNA containing 986 bp from the flanking regions of B20. In addition, a 1,040 bp PCR product, which was where the T-DNA was inserted, was amplified from P915. Finally, both full length T-DNA and the 1,040 bp fragment were simultaneously amplified in the F1 hybrids; P915 ${\times}$ B20, Pungchon ${\times}$ B20, Gumtap ${\times}$ B20. In the present study, we were able to identify zygosity among homozygous transgenic event B20, its wild type P915, and hemizygous F1 hybrids. Therefore, this novel zygosity identification technique, which is based on PCR, can be effectively used to examine gene flow for transgenic pepper event B20.

Architecture and Fashion mutually affects the shape and appearance of the other as an art of space according to the hybrid trends. Therefore, the purpose of this study is to find the correlations between the characteristics of traditional architecture types in Southeast Asia and modern fashion. Firstly, characteristics of the types obtained through the theoretical consideration of Southeast Asian architectural tradition include vertical, symmetrical, geometrical, epeated and continual structure. On the basis of these characteristics analyzed from 2013's S/S to 2015's F/W collection of Alexander McQueen, Gareth Pugh, Victor & Rolf, designers with strong creative and experimental minds who juxtaposed designs of two opposing points as well as hybrids since 2000, the following formativeness exists. First, the vertical structure of high floor is represented as a straight silhouette, a color contrast, vertical cut or wrinkle. Hence, it impresses verticality, rhythm, etc. Second, symmetrical structure of the gable roof is represented as a trapezoidal shape starting from the shoulder line or neck line widened into sleeves, impressing symmetry, dynamism, etc. Third, the geometry of the assembled is represented as vertical and horizontal bands or pattern pieces like puzzle, impressing geometry, three-dimensional, etc. Fourth, repeated structure of the weaving pattern is represented as repetitive patterns of woven fabric or printing techniques. Thus, it impresses repeatability, harmony, etc. And lastly, continuous group structure is represented as a connection of collars or hem-lines, as well as a crossing of fabric that impresses continuity, liquidity, etc.

The climate is changing rapidly, and this may pose a major threat to global biodiversity. One of the most distinctive consequences of climate change is the poleward and/or upward shift of species distribution ranges associated with increasing temperatures, resulting in a change of species composition and community structure in the forest ecosystems. The Baekdudaegan mountain range connects most forests from the lowland to the subalpine zone in South Korea and is therefore recognized as one of the most important biodiversity hotspots. This study was conducted to understand the distribution range of vascular plants along elevational gradients through field surveys in the six national parks of the Baekdudaegan mountain range. We identified the upper and lower distribution limits of a total of 873 taxa of vascular plants with 117 families, 418 genera, 793 species, 14 subspecies, 62 varieties, two forms, and two hybrids. A total of 12 conifers were recorded along the elevational gradient. The distribution ranges of Abies koreana, Picea jezoensis, Pinus pumila, and Thuja koraiensis were limited to over 1000 m above sea level. We also identified 21 broad-leaved trees in the subalpine zone. A total of 45 Korean endemic plant species were observed, and of these, 15 taxa (including Aconitum chiisanense and Hanabusaya asiatica) showed a narrow distribution range in the subalpine zone. Our study provides valuable information on the current elevational distribution ranges of vascular plants in the six national parks of South Korea, which could serve as a baseline for vertical shifts under future climate change.

당근의 기내 증식에 있어서 계대배양을 반복하더라도 분열능과 재분화능에 차이가 없고 변이가 생기지 않는 순 원기배양법을 확립코자 하였다. 엽 원기 2개가 붙은 경정조직을 BA 2.0 mg/L 와 NAA 0.2 mg/L 를 첨가한 MS 기본 액체배지에 치상하고 24시간 강한 광선 아래 2rpm으로 수직 회전배양하였을 때 순 원기가 유기되고 덩어리로 자라났다. 순 원기 유기는 공여친의 유전자형과 재배 계절 및 발육단계의 영향을 거의 받지 않는 것으로 판단되었다. 이 순 원기 덩어리는 사방 2~3 mm정도의 크기로 순 원기가 유기된 배지에 계대배양 하였을때 잘 증식되었는데 표면에 작은 신초를 가진 것과 그렇지 않은 것, 그리고 캘러스의 3가지 형태로 분화하였다. 표면에 작은 신초를 가진 것이 역시 표면에 작은 신초를 가진 순 원기 덩어리로 증식되었다. 이 표면에 작은 신초를 가진 것이 1/2MS 기본배지에 KN 0.2-1.0 mg/L 과 IAA 0.2~1.0 mg/L 를 첨가한 고체배지에서 주로 식물체로 잘 분화하였다. 일단 순 원기가 유기되어 덩어리를 형성한 후에는 1년 동안에 8.7$\times$$10^{12}$개의 비율로 증식될 수 있을 것으로 계산되었다. 그리고 13번의 계대배양 후에도 증식능에 차이가 없었으며 염색체상의 이상도 없었다.

본 연구는 욕지도의 관속식물상과 식생을 밝히기 위하여 2015년 3월부터 2016년 1월까지 총 6회에 걸쳐 21일간 현지조사를 실시하였다. 관속식물은 113과 354속 487종 4아종 50변종 4품종 2교잡종의 총 547분류군으로 정리되었다. 이 중 기존의 조사에서는 발견되지 않았으나 본 연구에서 처음으로 밝혀진 분류군은 314분류군이었다. 한반도 고유종 8분류군, IUCN 평가기준에 따른 적색목록식물 6분류군, 식물구계학적 특정식물 86분류군이 조사되었다. 본 조사지에서 다른 지역에 비해 특이적으로 분포하는 식물은 99분류군이며, 이 중 남방계식물은 97분류군, 제한분포 식물은 2분류군이 확인되었다. 귀화식물은 74분류군이 발견되었다. 욕지도의 산림식생은 곰솔군락과 사방오리군락이 주를 이루는 것으로 나타났다. 군락의 수직구조는 안정적이었으며, DBH-class 분석 결과 교목층의 우점종이 유지될 것으로 나타났다. 간벌과 같은 교란인자가 제거되면 초본과 목본종의 구성은 현재와 다른 양상이 나타날 것으로 보인다.
