전익기,이재돈,곽정현 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.6

Ntural Science including exercise physiology was stated as a main stream in Keunjong Cho's (1992) and Hanbum Cho's reports (1997) about the trends of gymnastic study and in Chihwan Ji's reports (1997) about Taekwondo study. I agree to the statements that the theses in the field of the natural science like mensuration and physiology are predominant. I anticipate as well that the study in the field of civic science such as sociology, psychology, sports industry and business management will get more activated. In relation to the identification of Taekwondo study, es pointed out by Chihwan Ji et al(1997), rmst frequent subject is the match, and leg-kick, physical strength, dynamics are surely major variants to be issued. But the clarification of the intrinsic mattes are relatively negligent. The identification of Taekwondo study needs to be set up through diverse approach to grade, smash, Taekwon Gym, and trial match. The position of Taekwondo study is expected be promoted along with the increased numbers of published theses (more than 100 p.a. since 2002). The studying environments to achieve a qualitative development in comparison with the quantitative development should be formed to secure the identity of Taekwondo. These efforts get to give an initiative to establish a Korean Society of Taekwondo which Taekwondo personnels have desired for a long time. Building a accurate and broadly comprehensive database system for various kinds of dissertations available at the library of National Assembly should be precedented.

20대 여성의 구두 착용에 따른 발의 장애분석

한현정,전은경 울산대학교 2005 생활과학논문집 Vol.7 No.1

본 연구의 목적은 현대여성의 구두 착용에 따른 발 및 주변 부위의 문제점을 밝히는데 있다. 본 연구에서는 주된 구두 소비자 계층인 20대 여성들을 대상으로 소비자 설문조사를 통하여 구두 착용현황 및 그에 따른 발 장애를 살펴보고 구두 제작시 필요한 기초자료를 제공하고자 하였다. 본 연구의 결과를 살펴보면, 구두 착용여성의 대부분이 연령과 착용시간에 관계없이 많은 장애를 경험하였다. 그러므로 구두장애 요인 중 가장 많이 지적된 ‘구두골 치수’와 소재의 개선이 요구된다. 특히, 발둘레 치수에 대해서는 소비자와 판매자의 인지도가 약해 적절히 사용되지 못하고 있으므로 KS 규격에 대한 홍보가 필요하다. The purpose of this study was to identify the problems of women’s feet and it’s relative area caused by wearing shoes. This study was conducted through a survey with 384 young women consumers of 20s. Most respondents indicated that problems while wearing shoes. The reasons of the discomfort were ‘unfit of the size’ and ‘inappropriate materials.’ Most respondents were found to have the knowledge of their sizes but not of the letter sizes for the foot girth. Seventy six percent indicated that they of the respondents rarely know about the letter size. Most of the respondents (92.5%) indicated that they never checked the letter size when purchased shoes. This implicates that consumer education concerning the ‘KS G 3405 Lasts for shoes’ size system is necessary.

황현정,전혜정,최근원,김영채 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

치커리와 쑥갓에 있어 식물조직배양이나 형질전환 과정에 필요한 무균 절편체를 얻기 위한 적절한 방법을 제안하기 위해 기내 파종을 위한 소독조건과 배지조성 및 종류에 관한 실험들이 실시되었다. 치커리 'Precole'은 10% NaOCl, 15분간, 'Chiavari'는 5% NaOCl, 15분간이 기내파종 시 발아 및 자엽전개를 촉진시키고 오염발생을 억제하는 조건으로 선발되었다. 쑥갓에서는 발아 및 자엽전개율에 있어 NaOCl 처리 간에 차이는 없었지만 10% NaOCl, 30분간 처리에서 가장 낮은 오염율이 관측되었다. 치커리와 쑥갓의 발아와 자엽전개율 모두 인조토양배지의 사용으로 MS 배지에 비해 현저히 향상 되었다. 비록 육안으로는 오염여부를 관측할 수는 없었지만 이들 인조토양배지에서 자란 쑥갓 묘의 자엽을 MS배지에 치상하여 배양 시에는 오염증상이 나타났으며 이들을 NaOCl 1%로 15분간 소독 후 치상한 결과 오염율을 현저히 낮출 수 있었다. Experiments on the sterilization condition and medium composition and type for in vitro sowing were conducted to suggest a proper way to produce enough aseptic explants for tissue culture or transformation study in chicory and garland chrysanthemum. Fifteen minutes soaking treatment with 10% NaOCl for chicory 'Precole' and 15 minutes with 5% NaOCl for chicory 'Chiavari' were selected as proper sterilization conditions to promote in vitro germination and cotyledon expansion and inhibit the seedling contamination from seed itself. In garland chrysanthemum, there was no significant difference in germination and cotyledon expansion ratio among NaOCl treatments, but the lowest seedling contamination ratio was observed by 30 minutes soaking with 10% NaOCl. Both germination and cotyledon expansion ratio in chicory and garland chrysanthemum were significantly increased by using the artificial soil media in contrast to MS media. Although seedling contamination with the artificial soil media could not be observed with bare eyes, cotyledon explants harvested from the plants grown on the media showed some fungal growth when they were placed onto MS media for further culture. However the percentage of the contamination from these explants was dramatically decreased by 15 minutes sterilization with 1% NaOCl.

Jeong, Sang Hyeon,Yang, Sung-Hyun,Jin, Hyun Mi,Kim, Jeong Myeong,Kwon, Kae Kyoung,Jeon, Che Ok International Union of Microbiological Societies 2013 International journal of systematic and evolutiona Vol.63 No.4

<P>Two novel Gram-stain-negative, chemoheterotrophic and strictly aerobic bacteria, strains GY2<SUP>T</SUP> and SPO729<SUP>T</SUP>, were isolated from a tidal flat at Gwangyang Bay in Korea and a marine sponge sample from the Pacific Ocean, respectively. The two strains were halotolerant, catalase- and oxidase-positive, and non-motile rods. Optimum temperature and pH for growth of both strains were observed to be 35 °C and pH 7.0–7.5, but optimum salinity for strain SPO729<SUP>T</SUP> [2–3 % (w/v)] was slightly higher than that for strain GY2<SUP>T</SUP> (1–2 %). The major cellular fatty acids of both strains were C<SUB>16 : 0</SUB>, iso-C<SUB>15 : 0</SUB>, iso-C<SUB>17 : 0</SUB>, iso-C<SUB>17 : 1</SUB>ω9<I>c</I>, C<SUB>18 : 1</SUB>ω7<I>c</I>, iso-C<SUB>11 : 0</SUB> and iso-C<SUB>11 : 0</SUB> 3-OH. The genomic DNA G+C contents of strains GY2<SUP>T</SUP> and SPO729<SUP>T</SUP> were 55.1 and 57.9 mol%, respectively, and ubiquinone 8 (Q-8) was detected as the sole respiratory quinone from the two strains. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains GY2<SUP>T</SUP> and SPO729<SUP>T</SUP> formed tight phyletic lineages with members of the genus <I>Microbulbifer</I>. Strain GY2<SUP>T</SUP> was closely related to <I>Microbulbifer okinawensis</I> ABABA23<SUP>T</SUP> (98.2 %), strain SPO729<SUP>T</SUP> (98.0 %) and <I>Microbulbifer donghaiensis</I> CN85<SUP>T</SUP> (97.0 %); strain SPO729<SUP>T</SUP> was closely related to <I>M. okinawensis</I> ABABA23<SUP>T</SUP> (98.3 %) and <I>M. donghaiensis</I> CN85<SUP>T</SUP> (98.2 %). The DNA–DNA relatedness values of strain GY2<SUP>T</SUP> with <I>M. okinawensis</I> ABABA23<SUP>T</SUP>, strain SPO729<SUP>T</SUP> and <I>M. donghaiensis</I> CN85<SUP>T</SUP> were 40.0±2.1 %, 13.1±3.9 % and 16.2±5.8 %, respectively, whereas those of strain SPO729<SUP>T</SUP> with <I>M. okinawensis</I> ABABA23<SUP>T</SUP> and <I>M. donghaiensis</I> CN85<SUP>T</SUP> were 48.0±4.0 % and 34.6±9.3 %, respectively. On the basis of phenotypic and molecular features, it is concluded that the two strains GY2<SUP>T</SUP> and SPO729<SUP>T</SUP> represent two novel species of the genus <I>Microbulbifer</I>, for which the names <I>Microbulbifer gwangyangensis</I> sp. nov. and <I>Microbulbifer pacificus</I> are proposed; the type strains are GY2<SUP>T</SUP> ( = KACC 16189<SUP>T</SUP> = JCM 17800<SUP>T</SUP>) and SPO729<SUP>T</SUP> ( = KCCM 42667<SUP>T</SUP> = JCM 14507<SUP>T</SUP>), respectively.</P>

본 연구는 다당체의 한 종류인 penta-O-galloyl-β-D-glucose (PGG)가 사람의 여러 조직에서 기원하는 여러 암세포주(A-549, MDA-MB-231, U87-MG, MCF-7 및 PANC-1), 정상 MRC-5 태아 섬유아세포 그리고 사랑니에서 유래한 간엽줄기세포(DPSCs)에 미치는 세포독성 효과를 조사하였다. IC50값은 다른 세포주에 비해 높은 증식률을 나타내는 A-549 및 MDA-MB-231 암세포주에서 유의적으로 낮게 관찰되었다. 10 uM의 PGG가 포함된 배양액에서 세포를 7일 동안 배양한 결과, 세포배가시간은 모든 세포주에서 유의적으로 늘어났고, 세포배가시간과 IC50값의 관계를 조사한 결과, 세포배가시간이 늘어남에 따라 IC50값은 비례적으로 증가됨을 증명하였다. 또한, 10 uM의 PGG로 처리된 세포주들은 노화와 관련된 ß-galactosidase의 활성도가 높게 관찰되었다. 특히, telomerase 활성도는 A-549 및 MDA-MB-231 암세포주에서 다른 세포주에 비하여 현저히 감소하는 것을 관찰하였다. 이러한 결과를 바탕으로 PGG는 높은 증식률을 보이는 암세포주에서 높은 세포독성효과를 나타내어 잠재적인 항암물질임을 증명하였다. The present study examined the cytotoxic effects of 1, 2, 3, 4, 6-penta-O-galloyl-β-D-glucose (PGG), known as the pentahydroxy gallic acid ester of glucose, in the various human cancer cell lines (A-549, MDA-MB-231, U87-MG, MCF-7 and PANC-1), normal MRC-5 fetal fibroblasts, and dental papilla tissue-derived mesenchymal stem cells (DPSCs). Significantly (p<0.05) lower half maximal inhibitory concentration (IC50) values were observed in the A-549 and MDA-MB-231 cells showing a high proliferation capacity, compared with other cancer and normal cell lines with a relatively low proliferation capacity. The population doubling time (PDT) was significantly (p<0.05) higher in the 10 μM PGGtreated cell lines than those of untreated control cell lines. The present study demonstrated that the IC50 value increases proportionally to the extending PDT. A high cell number with senescence-associated ß-galactosidase activity was also observed in the 10 μM PGG-treated cells compared with those of untreated control cells. Moreover, the level of telomerase activity was significantly (p<0.05) decreased with 10 μM PGG treatment, especially in A-549 and MDA-MB-231 cells showing a high proliferation capacity. Based on these observations, PGG could serve as a potent agent for cancer chemotherapy, as its treatment was more effective in cells with a high proliferation capacity.

In this paper, a conceptual design and a detailed design of novel cylindrical magnetic levitation stage is introduced. This is came from planar-typed magnetic levitation stage. The proposed stage is composed of cylinder-typed permanent magnet array and semi-cylinder-typed 3 phase winding module. When a proper current is induced at winding module, a magnetic levitation force between the permanent magnet array and winding module is generated. The proposed stage can precisely move the cylinder to rotations and translations as well as levitations with the magnetic levitation force. This advantage is useful to make a nano patterning on the surface of cylindrical specimen by using electron beam lithography under vacuum. Two methods are used to calculate required magnetic levitation forces. The one is 2D FEM analysis, the other is mathematical modeling. This paper shown that results of two methods are similar. An assistant plate is introduced to reduce required currents of winding module for levitations in vacuum. The mathematical model of cylindrical magnetic levitation stage is used for dynamic simulation of magnetic levitations. A lead-lag compensator is used for control of the model. Simulation results shown that the detail designed model of the cylindrical magnetic levitation stage with the assistant plate can be controlled very well.
