  • The purpose of this study was to understand changes of the current young generation's lifestyle, aesthetic attitude for an appearance, and way of thinking by making a close investigation into metrosexual, the recent mode, and find out its cultural and social implications. As a method of the study, the literature and the Internet data were reviewed. Articles from newspapers, magazines and the Internet were chosen roughly from the year 2000 to now because metrosexual mode remarkably boomed before and after 2000. Books related to the theory on the mode in a costume culture were referred. Also, articles in daily newspapers which dealt with cultural and social issues were reviewed, fashion magazines for men such as Esquire and GQ showing the new trend in men's lifestyle and fashion were examined, and the Internet providing us the latest news from cultural and social topics to fashion trends were investigated. The backgrounds of the rise of metrosexual mode were a collapse of stereotypes in various fields, spread of lookism in a visual image period, extension of commercialism, and expansion of men's character casual trend. Metrosexual was defined as an urban male with a strong aesthetic sense who spends a great deal of time and money on his appearance and lifestyle. His fashion style was characterized by slim and flowing silhouette, feminine and luxurious materials such as transparent chiffon, silk and cotton with a light and soft touch, and a knitted wear with a flowing line, a wide variety of vivid and pastel colors, floral and geometric patterns, and the decorative details like lace, beads, embroidery, and fur. From spread of this mode, two cultural and social implications were extracted. Firstly, the current young generation's aesthetic standards for the perfect man changed from macho man to considerate man who had a good appearance and this suggested that a conventional sex role broke down. Secondly, men began to explore for their own identity escaping from traditionally standardized masculinity that they had been forced to follow.

  • Background: Glycosylation of natural compounds increases the diversity of secondary metabolites. Glycosylation steps are implicated not only in plant growth and development, but also in plant defense responses. Although the activities of uridine-dependent glycosyltransferases (UGTs) have long been recognized, and genes encoding them in several higher plants have been identified, the specific functions of UGTs in planta remain largely unknown. Methods: Spatial and temporal patterns of gene expression were analyzed by quantitative reverse transcription (qRT)-polymerase chain reaction (PCR) and GUS histochemical assay. In planta transformation in heterologous Arabidopsis was generated by floral dipping using Agrobacterium tumefaciens (C58C1). Protein localization was analyzed by confocal microscopy via fluorescent protein tagging. Results: PgUGT72AL1 was highly expressed in the rhizome, upper root, and youngest leaf compared with the other organs. GUS staining of the promoter: GUS fusion revealed high expression in different organs, including axillary leaf branch. Overexpression of PgUGT72AL1 resulted in a fused organ in the axillary leaf branch. Conclusion: PgUGT72AL1, which is phylogenetically close to PgUGT71A27, is involved in the production of ginsenoside compound K. Considering that compound K is not reported in raw ginseng material, further characterization of this gene may shed light on the biological function of ginsenosides in ginseng plant growth and development. The organ fusion phenotype could be caused by the defective growth of cells in the boundary region, commonly regulated by phytohormones such as auxins or brassinosteroids, and requires further analysis.

  • Background: Prenyltransferases catalyze the sequential addition of isopentenyl diphosphate units to allylic prenyl diphosphate acceptors and are classified as either trans-prenyltransferases (TPTs) or cis-prenyltransferases (CPTs). The functions of CPTs have been well characterized in bacteria, yeast, and mammals compared to plants. The characterization of CPTs also has been less studied than TPTs. In the present study, molecular cloning and functional characterization of a CPT from a medicinal plant, Panax ginseng Mayer were addressed. Methods: Gene expression patterns of PgCPT1 were analyzed by quantitative reverse transcription polymerase chain reaction. In planta transformation was generated by floral dipping using Agrobacterium tumefaciens. Yeast transformation was performed by lithium acetate and heat-shock for $rer2{\Delta}$ complementation and yeast-two-hybrid assay. Results: The ginseng genome contains at least one family of three putative CPT genes. PgCPT1 is expressed in all organs, but more predominantly in the leaves. Overexpression of PgCPT1 did not show any plant growth defect, and its protein can complement yeast mutant $rer2{\Delta}$ via possible protein-protein interaction with PgCPTL2. Conclusion: Partial complementation of the yeast dolichol biosynthesis mutant $rer2{\Delta}$ suggested that PgCPT1 is involved in dolichol biosynthesis. Direct protein interaction between PgCPT1 and a human Nogo-B receptor homolog suggests that PgCPT1 requires an accessory component for proper function.

  • 자가화합성이고 3종의 육상 난초인 은난초, 금난초, 은대난초가 간혹 동소적 개체군들에서 동시에 개화한다. 흰꽃이 완전히 열리지 않는 은난초와 은대난초는 주로 자가수분하며, 밝은 노란색 꽃이 완전히 열리는 금난초는 꽃 내 먹이가 존재하는 듯 속이는 방법으로 곤충을 유인하면서 타가교배한다. 잡종의 형성은 강한 수분 장벽(꽃간의 구조적 격리) 때문에 종간에 거의 일어나지 않는다. 만약 이 들 3종이 종간 잡종화의 방지로 진화하였다면, 저자들은 3 종의 공간 분포 양상이 서로 공간적으로 분리(즉, '공간적 반발') 될 것으로 기대할 수 있다. 이 예측을 검증하기 위해 한국의 경상남도 연화산군립공원 내 동소적집단에서 동시개화하는 3 종류의 은대난초 종의 공간적 분포를 연구하였다. 각각 개체군에서는 개체들이 공간적으로 강하게 뭉쳐 있으나, 종 간에서는 이들이 공간적으로 서로 독립되어 있는 결과는 다른 종 들에서 보여준 기존 연구와 다르다. 저자들은 이들 은대난초속 종이 유사한 균근 형성 균류들을 공유함으로써 공간적으로 다소 무작위로 분포 해왔을 것이라는 가정을 제시한다.

  • 본 논문은 움직임 벡터의 높은 시$\cdot$공간 상관도 정보를 이용하여 계산량을 줄이면서 움직임 추정의 정확도를 높일 수 있는 새로운 블럭 정합 움직임 추정 방식을 제안한다. 제안된 방식은 기존의 고속 움직임 추정 방식들이 이용하는 탐색 영역내의 일관된 첫 번째 탐색 위치에서 움직임 벡터를 찾는 것이 아니라 움직임 벡터의 높은 시$\cdot$공간 상관도 정보를 이용하여 보다 정확한 탐색영역을 찾아 탐색 영역을 보정함으로써 보다 정확한 첫번째 탐색 위치를 중심으로 움직임 벡터를 탐색한다. 즉, 본 논문에서 제안하는 방식의 핵심은 움직임 추정의 정확도를 높이기 위해서 보다 정확한 첫번째 탐색 위치를 찾는 것이다. 따라서 움직임 벡터의 시간적인 상관성을 이용하기 위해서 현재 프레임 블럭과 같은 좌표를 갖는 이전 프레임 블럭의 방향성을 조사한다. 또한 공간적인 상관성을 이용하기 위해서 현재 프레임내의 이웃 블럭들의 방향성을 조사한다. 이러한 블럭들이 갖는 방향성을 바탕으로 움직임 추정을 위한 첫번째 탐색 위치를 결정하게 되고 그 위치를 중심으로 일정한 탐색 패턴에 따라 움직임 벡터를 탐색하는 방식이다. 실험 결과 제안된 방식은 기존의 대표적인 고속 탐색 방식들에 비해 PSNR (Peak-to-Signal Noise Ratio) 값에 있어서 평균적으로 1.7dB 개선되고 영상에 따라 최고 3.6dB 정도 우수한 결과를 나타낸다. 또한 탐색 횟수에서는 기존의 대표적인 고속탐색 알고리즘인 3단계 탐색 알고리즘 (Three-step search algorithm) 보다 평균 50% 이상을 줄일 수 있었고, 정확한 움직임 벡터를 찾는 비교에 있어서도 월등히 우수한 결과를 나타내었다. 또한 제안된 방식은 정량적인 결과뿐만 아니라 부호화 후 복호화한 영상의 화질에 있어서도 다른 고속 탐색 알고리즘 보다 월등히 우수한 화질을 제공한다. 및 상품과율 등이 모두 10:0 양액보다 높게 나타났다. 식물체내의 무기성분은 8:2의 경우 K+ 및 Mg2+는 잎에서 Ca2+은 뿌리에서 많았으며 PO4-은 과실과 줄기에서 많았다. 10:0에서의 무기성분도 8:2에서와 같은 경향을 나타내었으며, 배지간에 무기성분의 차이는 인정되지 않았다. 양액조성에 따른 무기성분 함량의 차이는 K+, Ca2+ 및 Mg2+는 10:0에서, PO4-은 8:2에서 각각 많았다.uage.

  • This thesis is a study on the kaftan styles iin Asia. The purpose of he study was to examine the origin o the kaftan concentrating on the history and cultural backgrounds of nomads in he Western Central and North Eastern Asia. Secondly for more thorough study and expla-nation on how these kaftans contributed to East-West trade along the silk road. wall paintings and miniature illuminations along Oasis roads persia and Saracen period were compared, Also real kaftans were compared and analyzed the characteristics of Western (Turkey palestine) Central(Kazakistan Uz-bekistan Tadzhistan Qyrgyztan Turkmenistan) and the North Eastern Asian(Mongol) area. Thirdly an attempt has been made to provide the North Eastern Asian(Mongol) area. Thirdly an attempt has been made to provide the style classifications according to their peculiarities of the various kaftans as well as how kaftan gave important influences on custumes of different religious sects. The kaftan is a long coat-like garment with front openings fastened with long sash having an extra long sleeves which were worn by middle and high class nomadics throughout the West Central and North Eastern Asia This type of kaftans were a basic clothing for nomadics since they were constantly moving fromone to another areas on their horse back riding. They also wore tight trousers with boots. Kaftans seem to be originated from nomads of Steppe around B.C. 800 On B. C 400 west asian areas such as Solokha Kul-oba Kulogan had pictures sculptues on vases showing kaftans of half coat type length with front opening tied with band. Also the materials used were the products of animals such as wool or felt with animal designs showing Scythian nomads. In the North Eastern Asia Hsiung-Nu were active in Kazakha North Altai and Mongol The Clothing and fabrics exfavated near Noin-ula Pazyrik showed many samples of kaftan with trousers with other interment be-longings with a corpse around B.C 300 to A. D 100 when trades along the silk roads were proven by many historians Kaftans excavated in this area wore red front opening silk materials which suggesting settling down of nomads. in he central Asia Dol-gull near Altai mountain area were mainly miners who later had many trades with Persia and Bizantine. After Dol-gull Bezeklik temple Samarkant Kizil cow Budda sculture wall paintings of Astana tomb showed typical kaftan of this re-gion. These were both hip covered length as well as long coat with narrow sleeves. Es-pecially they had different color band fron the main kaftan with grogeously and splendously designed silk. In perusia during A. D 1400 to 1600 minia-ture illumination showed kaftan as a high class symbol more than clothing purpose. They had best quality silk with extra long sleeves draping and had a layers of kaftans one on top of anther as a symbol of wealth These Kaftans with different colors and designs were even more beautiful with their effective combinations and contrast of colors. On the other hand the lower class common people and servants wore simple kaftan with the front part of the kaftan were slipped into the belt in order to be more active and con-venient to work, The real kaftans discovered at Topkapi Saray palace of Turkey from A. D 1300 to 1900 were also compared. These kaftans were very numerous in numbers as well as designs The materials and designs used were also vari-ous such as Chinese to Italian silk. The shaped and pattern itself were not much different from the previous nomad's Kaftans. The Palestian kaftans remained were from the beginning of 19th and 20th century. Since this area is hot and dry desert they used black and navy blue colors mostly in order to exclude the sun lights. The patterns used were similar to Nomads and Bedouin with cross stiches and patch work decorations. In the central Asia they had similar life style and natural environmental cnditions with Turkish tribe which resulted in similar kaftan styles as nomads. Mongols conserved basic patterns of kaftan since Cinggis Khan with deep folding in order to keep warm. At last the kaftans studided in this thesis were classified in to four such as half coat long coat jacket and vest style. A pattern used in the Central Asia were zigzag and ani-mal design whereas in the West Asia were floral plant arabesk and circle pattern. As I discussed previously kaftan styles of nomads in the Asia maintained its basic pat-tern throughout the history except slight changes in color gusset sleeve shapes. These slight changes were made according to the need to adapt the need of environmental natu-ral conditions, The reason for aboriginality of kaftan in Asia was its simplicity and con-venience Most interesting fact is that for all these years Mongols are still wearing kaftan in their life ensuring us that they art the preserves of old kaftan. Since this thesis dealt enormous Asian regions I had a limitation of not being able to cover the Far Esatern asian areas such as Korea China and Japan how these kaftans were influenced in their clothing history as well as Eastern and Western culture. This topic along with the studies on materials and designs of patterns of kaftan will be another research project in the future.

  • 전통민속식물지식이 빠르게 사라져 가는 상황에서 전통식물지식에 대한 기초조사를 통한 기록이 매우 중요한 과제가 되었다. 민속식물학 조사에서 조사강도와 민속식물정보, 식물종 정보의 증가에 관련성은 가장 중요한 과제이다. 본 연구에서는 국립수목원에서 발간된 자료를 이용하여 한반도 민속식물에 대한 메타 데이터를 DB화하여 분석하였다. 전통민속식물지식의 종풍부도에 추정은 ACE, Chao1, Chao 2, ICE, Jack 1, Jack 2, Bootstrap 등의 추정식을 이용하여 제시하였다. 종누적곡선 분석에서 지역별 종누적이 다른 양상을 보여 강원도의 누적곡선은 상대적 샘플링 노력이 더 필요하며충남 지역의 경우 조사 강도에 비해 일찍 수평선에 점근하는 특성을 보여 이지역의 조사 강도가 실제 정보량의 증가에 비해 높았다. 식용, 약용, 공예용 등의 종풍부도는 남녀간의 지식이 분포가 차이가 있음을 확인하였다. 주변환경의 식물상과 비교분석을 통해 일부 지역의 경우 민속식물조사가 상대적으로 조사량이 부족하고 추가 조사시 더 다양한 종이 발굴 될 것으로 예상된다.

  • The ubiquitin-proteasome pathway is the major regulatory mechanism in a number of cellular processes for selective degradation of proteins and involves three steps: (1) ATP dependent activation of ubiquitin by E1 enzyme, (2) transfer of activated ubiquitin to E2 and (3) transfer of ubiquitin to the protein to be degraded by E3 complex. F-box proteins are subunit of SCF complex and involved in specificity for a target substrate to be degraded. F-box proteins regulate many important biological processes such as embryogenesis, floral development, plant growth and development, biotic and abiotic stress, hormonal responses and senescence. However, little is known about the F-box genes in wheat. The draft genome sequence of wheat (IWGSC Reference Sequence v1.0 assembly) used to analysis a genome-wide survey of the F-box gene family in wheat. The Hidden Markov Model (HMM) profiles of F-box (PF00646), F-box-like (PF12937), F-box-like 2 (PF13013), FBA (PF04300), FBA_1 (PF07734), FBA_2 (PF07735), FBA_3 (PF08268) and FBD (PF08387) domains were downloaded from Pfam database were searched against IWGSC Reference Sequence v1.0 assembly. RNA-seq paired-end libraries from different stages of wheat, such as stages of seedling, tillering, booting, day after flowering (DAF) 1, DAF 10, DAF 20, and DAF 30 were conducted and sequenced by Illumina HiSeq2000 for expression analysis of F-box protein genes. Basic analysis including Hisat, HTseq, DEseq, gene ontology analysis and KEGG mapping were conducted for differentially expressed gene analysis and their annotation mappings of DEGs from various stages. About 950 F-box domain proteins identified by Pfam were mapped to wheat reference genome sequence by blastX (e-value < 0.05). Among them, more than 140 putative F-box protein genes were selected by fold changes cut-offs of > 2, significance p-value < 0.01, and FDR<0.01. Expression profiling of selected F-box protein genes were shown by heatmap analysis, and average linkage and squared Euclidean distance of putative 144 F-box protein genes by expression patterns were calculated for clustering analysis. This work may provide valuable and basic information for further investigation of protein degradation mechanism by ubiquitin proteasome system using F-box proteins during wheat development stages.

  • 본 연구는 의정부역과 연접한 캠프 홀링워터 미군공여지의 이전과 관련하여 대상지에 의정부시 도심지의 특성을 고려하고, 환경요구에 대한 적절한 기능을 수용하며, 독창적인 경관을 보여주기 위한 도심형 공원 현상설계의 내용을 토대로 작성하였다. 계획을 위한 사고의 바탕은 대상지의 특성에 따라 요구되어지는 광장과 공원을 합리적으로 융합하고, 역세권지역에 입지한 공원이 갖추어야 할 도시적 맥락을 반영하고 환경 친화적 공간의 실현방안들을 도출하는데 중점을 두었다. 이를 위한 기초연구로 도심형 광장의 유형에 대한 검토와 현대도시공원의 경향과 관련한 계획적 특이사항 및 미래에 대한 공원의 적응 방법들을 파악하여 계획의 내용에 반영하였다. 공간 운용을 위한 특이사항으로는 계획되어진 프로그램에 의하여 공간을 체험하기보다 미래의 변화에 유연하게 대처할 수 있도록 환경과 연계된 이용자들의 자발적 행동에 의하여 공간의 특성이 만들어지도록 디자인의 차별성을 검토하여 적용하였는데 계획상에 나타난 설계의 주안점은 다음과 같다. 첫째, 건물과 특정 공간에 의하여 수동적으로 만들어지는 광장의 형태를 벗어나, 도시의 구조적 맥락과 이용행태를 수용할 수 있는 비움의 공간으로 조성하여 변화하고 성장하는 도시생태에 적합한 장으로서 그 역할을 담당하게 한다. 이러한 오픈스페이스들은 도시의 성장에 대처할 수 있는 지속적인 맥락을 가지며, 이용행태의 변화와 시간적 추이에 따른 자생적 프로세스를 가지며 유지될 것이다. 둘째, 공원과 도시 그리고 인공적인 것과 자연적인 것은 현대의 도시환경 속에서 공존하고 상호 교감하며 네트워킹 되어야 한다는 내용을 담고 있다. 따라서 공원은 도시 내에 격리된 하나의 녹지 섬이 아니라 인접한 상업시설, 공공시설, 주거단지들의 오픈스페이스에 대한 요구를 수용하는 열린 공간이 되며 다양한 프로그램을 수용할 수 있는 터를 마련하고 있다. 셋째, 탄소저감과 함께 제로시티의 바탕이 되는 환경 친화적인 공간을 만들고 유지하기 위하여, 물리적인 계획과 함께 흥미로운 체험디자인 방법들을 반영함으로써 직 간접적인 생활 교육의 효과를 유도하도록 계획하였다.
