박윤미,방일수,Park, Yoon-Mee,Bang, Iel-Soo 한국미생물학회 2012 미생물학회지 Vol.48 No.2

인은 인지질, 탄수화물 및 핵산 등의 생분자 합성에 필요한 원소이다. 세균은 외부환경으로부터 인산이나 인산을 포함하는 영양소를 흡수하여 인을 얻고, 세포대사에 사용되고 남은 인산은 polyphosphate 형태로 저장한다. 현재까지 알려진 다섯 개의 인산 수송 시스템 중, 인산에 특이적으로 높은 친화력을 갖는 Pst 시스템이 가장 중요한 역할을 하며, 그 발현은 세포외부 인산 농도에 반응하는 PhoB-PhoR two component 신호전달 시스템에 의해 조절된다. 반응 조절 단백질 PhoB는 인산 대사뿐 아니라 이와 관계없는 유전자들의 전사를 조절하는 것으로 알려졌으며, 따라서 PhoB의 활성이 조절되지 않으면 많은 종류의 다른 표현형이 나타난다. 본 총설은 각 인산 수송 시스템의 기능이 결여된 세균의 표현형에 대한 최근 연구 결과를 토대로 다음과 같은 내용을 기술하였다. 첫째, 세포 내부 인산의 적정 농도 유지를 위한 인산 수송 시스템들의 역할, 둘째, 인산뿐 아니라 여타 환경 신호와 관련된 수송 시스템의 다양한 표현형, 그리고 마지막으로, 수송 시스템들 간 혹은 그 조절자들 간의 표현형 중복을 분류하여 제시하였다. 이러한 내용은 결국 세균의 대사, 적응반응 및 병원성 발현에 미치는 인산 항상성의 중요성을 강조한다. Phosphorous is an essential element for the synthesis of various biomolecules including phospholipids, carbohydrates and nucleic acids. Bacterial cells can uptake it as forms of phosphate and phosphate-containing nutrients from extracellular environments, and reserve extra phosphate to polyphosphate inside the cell. Among five phosphate transport systems, Pst plays central roles in phosphate transport, and its expression is coordinated by the regulation of PhoB-PhoR two component signal transduction system in response to extracellular levels of phosphate. Genomic studies on the response regulator PhoB reveal many genes independent of phosphate metabolism. Based on recent findings on phenotypes of bacteria lacking proper function of each phosphate transport system, this review discusses roles of phosphate transporters in maintaining optimum intracellular phosphate levels, and presents diverse phenotypes of phosphate transporters related with other environmental signals as well as phosphate, then finally points out functional redundancy among phosphate transport systems or their regulators, which emphasize importance of phosphate homeostasis in governing metabolism, adaptation, and virulence of bacteria.

This is a research about the fabrics attached to the remains of the Okjeon old tomb which was built around the early 5th century to the mid of the 6th century. Most of the remains have one kind of fabric attached to them, but there are cases where different sorts of fabrics are attached, where one kind is attached in layers, and there are also cases where the layer is made of different types of fabrics. Although they are made of warps and wefts with no twists, there can be an S twist on the weft or on both the warp and weft, and only one Z twist can be seen. There are 81 fabrics of plain weaved, one of transformed plain weaved and five 4-end complex gauze in these remains. The sparsest plain weaved fabric has the density of 7.4 strands/cm, while the most dense fabric has the density of 148.2x129.1 strands/cm and 0.046x0.061/mm thickness in thread. All the fabrics observed by SEM are hemp except one silk.

This study regards the understanding of previous research of dahoe, retention of weaving technique, and current status of the looms used weaving the dahoe. Review of the previous research consists of 23 thesis, 23 journal articles, and 13 books, which contents were studied and analyzed. The previous studies usually handles the history and methods of making the knots that use the dahoe, studies on dahoe itself has been done only recently on relics from the Joseon dynasty. Only four thesis has information on the methods of making and restoring dahoe. There were no books studying dahoe, and only few previous studies focused on the matter. The looms currently used by the artisans are the loom used in Namwon, loom made by Kim Hee Jin, or a modified version of either looms. There are numerous kinds of looms used for weaving dahoe: plain weave and double weave are weaved on simple handlooms, inkle looms and multi-heddles-treadles loom. For braiding, Japanese dakadai looms were imported or made, knitting has been weaved by only one artisan using a loom that she had designed, and the rest used ayadakekai. There has been many wrights in the Joseon era, that they were managed separately from the knots or dahoe, but today the use of dahoe is limited to the material for knots. Systematic research and restoration is needed not only in studies on looms, but also in dahoe where technical information and data is very limited.

The fabrics attached to the remains of the Okjeon old tomb in the Kaya period were examined. Most of fabrics examined were composed of hemp and silk. Considering that silk was found in the old tomb of the Kaya period in the late 5th century and that various kinds of silk were used in the other area, silk was assumed to be used before 5th century in the Kaya period. Only the structure of the densely plain weaved fabrics were analysed as silk and the other physical properties of the fabrics could not be investigated since the examined fabrics were tightly attached to the metal remains. Although most of the examined fabrics were plain weaved, an altered structure with twill and plain weaving were found indicating that diverse weaving structures were used in the Kaya period. This indicate a certain level of cultural exchange between Kaya and Silla, PaikJae, Kokuryo and weaving technique were almost similar in the Korean peninsula in the 5th century.

The world renowned traditional fabric Hansanmosi and the weaving of it is an Important Intangible Cultural Heritage of Korea and is also listed on the UNESCO Representative List of Intangible Cultural Heritage of Humanity. China’s Wanzaixiabu is a national Important Intangible Cultural Heritage and Japan’s Echigojofu Ojiyachijimi is also a national Important Intangible Cultural Heritage and listed on the UNESCO Representative List of Intangible Cultural Heritage of Humanity. These three types of ramie are made differently depending on the environment and culture. A few of the main characteristics of Hansanmosi is that the spinning is done on the lap and it is woven into fine ramie. Wanzaixiabu is made more for export than domestic use, therefore large quantities are made with variety of techniques and materials. Echigojofu Ojiyachijimi has crimped appearance, various products and is bleached in snow embodying regional features. Many ways to revitalize the Hansanmosi have been suggested. Food and clothing using Hansanmosi have been developed to help the advance in related industry. Based on the comparison of ramie from the three different countries, this study offers a diversification of Hansanmosi concentrating on the weaving techniques; suggesting variations in the weaving loom, dyeing methods, and materials and also to provide the various standards of Hansanmosi to promote utilization. However, such diverse methods must be carried out in parallel to the proper passing down of Hansanmosi.

본 연구는 백제고분에서 출토된 유물의 실물조사와 문헌을 중심으로 백제시대의 직물문화를 고찰하고자 한다. 백제의 고분에서는 마직물, 견직물, 면직물 등 다양한 종류의 직물이 발견되었다. 조직 기법은 평직, 능직, 중조직, 익조직, 편직, 엮음직 등의 여러 기법이 사용되었으며, 특히 평직의 경우 실의 굵기와 꼬임, 그리고 밀도를 달리하여 다양한 견직물을 직조하였다. 이 가운데 직물명칭이 규명된 사(紗), 곡(穀), 능(綾), 라(羅) 등이 있지만 경무직의 견을 비롯하여 규명되지 못한 직물들도 상당수가 조사되었다. 자수품의 전체를 확인할 수 있는 직물은 발견되지 않았으나 사슬수, 변수, 가름수, 사뜨기 등의 기법을 사용한 직물이 조사되었다. 실물 유물에서 조사된 직물의 특성으로 당시의 직기유형을 유추해보면 간단한 요직기뿐만 아니라 답판식 다종광다섭기가 존재했었다는 것을 알 수 있다. This research studies the textile culture of the Baekje dynasty through examining the artifacts from Baekje tombs and records. Various textiles such as hemp, ramie, silk, cotton and other artifacts were found from the Baekje tomb. Taffata, twill, warp-faced compound weave, leno, twining, braid and others were the weaving techniques that were used. Especially for taffata, threads with different thickness and twist were used to weave various textiles. It is evident that not only simple backstrap loom but also treadle type multi-harness looms existed to weave suc htextiles. There were no textiles to confirm the complete embroidery work. However, textiles that used chain, button-hole, open seam, and satteugi stitch techniques were found.

Uiwon-gun (1661-1722) and Sim Ikchang (1652-1725) were people of the upper classes of the Joseon Dynasty, who’s belts woven with thread were found in their graves. The purpose of this study is to find a term suitable for the belts of these two people and to reveal the characteristics of the two belts and decipher the 8-character text marked on Shim Ikchang’s belt to understand its meaning. The terms used during the Joseon Dynasty related to woven belts include “Gwangdaho”, “Daeja”, “Bunhapdae”, “Sagagda”, “Bangseungah”, and “Samunjikdae”. Among these terms, “Gwangdahoe” is the most suitable to indicate the belts of for both belts. The belts are made of a silk fabric of narrow width. The size of Uiwon-gun’s belt is 2.8× 199cm, and because it is folded in half lengthwise and sewn, the original width is 8cm. It was woven in the imitation gauze technique. Sim Ik-chang’s belt measures 10.5×258cm and is decorated with a woven net at the end. There are water and mountain patterns on both ends of the belt, with 11 lines of flower patterns equally spaced between. The belt is damask, the inscription part is made of brocade with letters expressed in golden thread. The meaning of the inscription is “Made in Hanbu. May you live a long and healthy life”.
