Development of Desk for Public Reading in Library
Kang, Myung-Sun,Chang, Yub Korea Furniture Society 2008 한국가구학회지 Vol.19 No.6
Through this study, I developed a new-styled desk for public reading in library in consideration of the characteristics of the company "KIFURS Co., Ltd." established and branded by a part of the members of the association 'Gyeonggi-Incheon Furniture Industry Cooperative', in the background of growing library-furniture market situation according to the government policy and the related participations of competitive companies. The differentially designed product was herein presented by introducing the function of office furniture and related material, by giving the existing product some improvements on the basis of the domestic and international data searching. The characteristic of the developed product is that the basic structure of the desk for public reading is easy to assemble & disassemble and also variable to be extended & modified. This basic structure is available to be mass production and to be pricewise through using aluminum. Furthermore it can be used as other library-furniture and office furniture, too. Also the luxury image was pursued by modern shape and different material, unlike the existing library-furniture.

의료기기산업의 급속한 발전에 따라 전파응용기술을 접목한 다양한 응용설비들이 개발되고 있으며, 그 중 고주파응용 전기수술기의 전자파 장해시험이 증대되고 있는 추세이다. 이에 따라 국내전파사용환경을 고려한 고주파응용 전기수술기의 체계적이고 합리적인 전자파장해 평가방법에 대한 연구를 하였다.

본 연구에서는 물과 비 혼합 비 공비 물질을 작동 유체로 사용하는 가시화 실험 장치를 제작하여 열유속을 증가시키 며 시간에 따른 벽면온도 특성과 내부 유동를 카메라로 연속 촬영하며 2유체 열사이폰의 내부의 유동 및 열전달 특성에 대하 여 가시적 방법으로 실험을 수행하여 실험 결과로부터 다음과 같은 결론을 얻을 수 있었다. 물과 FC40을 사용한 비 혼합 2유체 열사이폰은 열유속의 크기에 따라 자연대류, 펄스비등, 연속비등의 세가지 영역으로 구분 되었으며 비등은 증기압이 낮은 물에서 발생하였다. 자연대류에서는 액체 풀에서 물의 증발과 대류 액막 유동이 발생하였다. 액체 풀에서 비등이 발생할 때에는 강한 비등에 의하여 FC40과 물의 혼합된 상태로 전 영역에 걸쳐 기-액 이상 유동이 발생하였다. This study presents experiments to visualize the internal flow and heat transfer characteristics of thermosyphon with immiscible of water-FC40 adopted as binary working fluid. Three different regimes depending on the amount of heat flux applied to the thermosyphon were observed: natural convection, pulse boiling, and continuous boiling. Boiling incipience took place in water, which has lower vapor pressure than FC40. During natural convection water was vaporized in liquid pool while liquid film flows were formed. On the other hand, meanwhile bubbles were generated in the liquid pool during pulse and continuous boiling, the binary working fluid of water-FC40 was observed as the mixture throughout a whole range of the thermosyphon.

To investigate the structure-antagonistic relationship of the cyclohexapeptide L-659,877, a selective NK-2 tachykinin receptor antagonist, seven analogues were chemically synthesized by a solid phase method. The agonistic and antagonistic activities of the analogues were evaluated by contraction assay using the smooth muscle of guinea pig trachea (GPT) containing the NK-2 receptor. It was shown that the aromatic ring of Phe at position 3 and the sulfur group of Met at position 6 in L-659,877 were essential for binding to the NK-2 receptor. Decrease in antagonistic activity of L-659,877 caused by substituting Leu for Nle at position 5 indicates that the γ methyl group and side chain length of Leu plays an important role in its antagonistic action. Although the activity was slightly lower than L-659,877, cyclo [βAla^8]NKA(4-10) (analogue 1) showed potential antagonistic activity for the NK-2 receptor. It was confirmed that the expansion of the ring in L-659,877 by substitution of βAla for Gly at position 4 stabilized its conformation monitored by CD spectra. The results suggest that analogue 1 can be used as a new leader compound to design a more powerful, selective, and stable NK-2 receptor antagonist.

사람 인터루킨-2(IL-2)의 cDNA 클론을 oligo-누클레오티드를 primer로 사용하여 분리하였다. 사람 leukaemic T-cell line인 Jurkat 세포로부터 mRNA를 분리 하였다. ss-cDNA를 합성하기 위하여 인터루킨-2를 코딩하는 mRNA의 3' 끝쪽에 상보적인 30 mer oligo-누클레오티드를 역전사 반응시 primer로 사용하였으며, ds-cDNA를 합성하기 위해서는 만들어진 ss-cDNA의 3' 끝쪽에 상보적인 oligo-누클레오티드를 primer로 사용하였다. 이 ds-cDNA를 사용하여 partial cDNA library를 만든 뒤 cDNA 합성에 사용한 oligo-누클레오티드를 probe로 사용하여 콜로니 hybridization을 하여 인터루킨-2 cDNA를 찾기위하여 screen하였다. 약 200개의 transformants 중에서 세 클론이 positive signal을 나타냈다. 제한효소지도를 작성하고 누클레오티드 염기서열을 결정함으로써 이들 세 클론이 모두 인터루킨-2 cDNA를 포함하고 있음을 밝혔다. 이 결과는 우리가 만든 partial cDNA library에 인터루킨-2 cDNA가 Taniguchi 등 (1983)이 만든 total cDNA library에 들어있는 것보다 약 300배 가량 증가되어 있음을 시사한다. A cDNA clone for human interleukin-2 (IL-2) was isolated by using oligonucleotides as primers for the first and the second cDNA syntheses. Total RNA was prepared from Jurkat, a human leukaemic T-cell line, cells and mRNA was isolated. To synthesize ss-cDNA, a 30 mer oligonucleotide was used as a primer in the reverse transcriptase reaction. The sequence of the oligonucleotide was complementary to the 3' end of the coding sequence of IL-2. ds-cDNA was synthesized by DNA polymerase reaction using another oligonucleotide as a primer. A partial cDNA library was prepared using the ds-cDNA and screened for the presence of IL-2 cDNA by colony hybridization using the same oligonucleotides that were used in the cDNA synthesis reactions as probes. Three out of 200 transformants showed positive signals. Analysis of these three clones by restriction enzyme mapping and nucleotide sequencing showed that all of them contained IL-2 cDNA. Our results indicated that the IL-2 cDNA was enriched in the partial cDNA library about 300 fold over the population of IL-2 cDNA in the total cDNA library reported by Taniguchi et al. (1983).

Ovarian remnant syndrome is a rare condition which develops when functional ovarian tissue is left in situ after intended bilateral oophorectomy. It produces clinically significant syndrome, namely chronic pelvic pain and dysmenorrhea. Although the true incidence of this syndrome is unknown, an apprant increase in incidence has been reported. We have experienced a case of ovarian remnant syndrome showing chronic pelvic pain and palpable abdominal mass after difficult gynecologic operation. So, we report this case with a brief review of literatures.
