  • The purpose of this study was to compare muscle activity in the lower extremity during walking wearing jogging and roller shoes. Twelve male middle school students (age: 15.0 yrs, height 173.7 cm, weight 587.7 N) who have no known musculoskeletal disorders were recruited as the subjects. Seven pairs of surface electrodes (QEMG8, Laxtha Korea, gain = 1,000, input impedance >$1012{\Omega}$, CMMR >100 dB) were attached to the right-hand side of the body to monitor the rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), tibialis anterior (TA), and medial (GM) and lateral gastrocnemius (GL) while subjects walked wearing roller and jogging shoes in random order at a speed of 1.1 m/s. An event sync unit with a bright LED light was used to synchronize the video and EMG recordings. EMG data were filtered using a 10 Hz to 350 Hz Butterworth band-passdigital filter and further normalized to the respective maximum voluntary isometric contraction EMG levels. For each trial being analyzed, five critical instants and four phases were identified from the recording. Averaged IEMG and peak IEMG were determined for each trial. For each dependent variable, paired t-test was performed to test if significant difference existed between shoe conditions (p<.05). The VM, TA, BF, and GM activities during the initial double limb stance and the initial single limb stance reduced significantly when going from jogging shoe to roller shoe condition. The decrease in EMG levels in those muscles indicated that the subjects locked the ankle and knee joints in an awkward fashion to compensate for the imbalance. Muscle activity in the GM for the roller shoe condition was significantly greater than the corresponding value for the jogging shoe condition during the terminal double limb stance and the terminal single limb stance. Because the subjects tried to keep their upper body weight in front of the hip to prevent falling backward, the GM activity for the roller shoe condition increased. It seems that there are differences in muscle activity between roller shoe and jogging shoe conditions. The differences in EMG pattern may be caused primarily by the altered position of ankle, knee, and center of mass throughout the walking cycle. Future studies should examine joint kinematics during walking with roller shoes.

  • 김용호의 필모그래피는 한 줄로 요약하기 힘들다. 지난 20여 년간 광고 지면과 미술관, 광고 사진과 순수 사진을 오가며 경계나 영역을 한정짓지 않고 왕성한 활동을 해왔다. 김용호가 직접 언급한 포토랭귀지는 사진을 찍기 전 스스로 가상의 이야기를 먼저 지어내고 내용을 사진으로 시각화하는 것이다. 일반적으로 광고 사진은 제품을 팔기 위한 목적이라 일회성으로 그치는 경우가 많고, 대부분 화려한 조명과 배경 아래 제품을 촬영한다. 그러나 김용호는 이러한 광고 사진의 고정관념을 벗어나 매우 독특한 작품을 발표해 인정 받았다. 작가가 작업한 광고 사진은 단순히 제품의 세부정보나 기능을 보여주는 것이 아니라, 제품에 관한 독창적인 스토리를 만들어 소비자들이 누리고 얻을 수 있는 가치와 문화를 전달한다. 여러 편의 작품 중 현대카드 광고 <우아한 인생, 2012>은 다양한 매체를 통해 작품이 소개된 후, 이례적으로 사설 갤러리의 초청을 받아 전시되고 판매까지 되었다. 사진이 판매되었다는 것은 소장가치가 높다는 의미이고, 전시되었다는 것은 예술작품으로 인정받았다는 의미이다. 본 논문은 한국을 대표하는 광고 사진가 김용호의 작품을 중심으로 포토랭귀지에 관한 내용이다. 이를 위해 본론에서 다룬 연구문제는 디지털 시대의 사진과 언어, 스토리텔링 광고 전략, 김용호 작품 분석이다.

  • 국내(國內)에서 생산(生産)되는 시유(市乳)와 유제품(乳製品)의 riboflavin함량(含量)을 분석(分析)하고 병우유와 폴리팩우유, 흰우유와 초코렛색의 우유를 대비(對比)시켜 일광(日光)에 예민한 riboflavin의 함량변화(含量變化)를 추적한 결과(結果)를 요약(要約)하면 다음과 같다. (1) Riboflavin의 함량(含量)은 시료 100g당 병우유 흰것 $62.4{\mu}g$, 폴리팩우유 $62.4{\mu}g$, 초코렛우유 $61.5{\mu}g$, 커피우유 $62.5{\mu}g$, 바나나우유 $87.7{\mu}g$, 딸기우유 $89.3{\mu}g$, 발효유 $36.2{\mu}g$, Hard ice cream bar $130.4{\mu}g$, vanilla soft ice cream $195.9{\mu}g$이었다. (2) 한시간 일광(日光)노출후 병우유 72.4%, 폴리팩우유 77,7%, 두시간 경과후 병우유가 92.0%, 폴리팩우유가 91.4%로서 폴리팩우유가 riboflavin이 약간 빨리 파괴되는 경향(傾向)을 보였으나, 두시간 경과후의 파괴율은 서로 비슷하였다. (3) 1시간 일광(日光)노출후 초코렛색 우유는 36.1%, 흰우유는 72.4%, 두시간 후에는 초코렛색 우유 46.3%, 흰우유는 92.0%의 riboflavin의 파괴율을 보여 초코렛우유가 훨씬 파괴율이 적었다. 이상의 결과(結果)로 미루어 특히 여름철의 일광(日光) 노출은 riboflavin의 막대한 손실이 올 수 있음을 알 수 있었고 초콜렛색의 우유가 흰우유 보다 일광(日光)노출에 대한 riboflavin의 보존(保存)에 효과적이었다.

  • Knit products which had been limited only to underwear, recently became popularized, fashionized and highly classified covering even outer garments such as sportswear like golfwear, woman's dress, and man' s suit. As fashion cycle is getting shorter and the more a nation advanced prefers knit to woven fabrics knit industry has a very bright prospect, particularly woman's knit which is sensitive to fashion can be said as a fashion product with high value added. This study is to grasp the physical properties of stitch which are fundamental to the development of knit products. For this purpose, 2/20s of 100% wool were woven by the author of this study to basic plain stitch, rib stitch, varied transfer stitch, and float stitch on a SEMASEIKI cross knitter 7G to test the physical properties, and the result was as follows; 1. As for the relation between knit stitch and rate of extension recovery, rate of extension recovery was higher in the course direction than in the wale direction of three stitches except transfer stitch; rib stitch showed the highest rate of extension recovery in the course direction while float stitch showed the highest rate of extension recovery in the wale direction. 2. As for the relation between knit stitch and bursting strength elastic rib stitch showed higher bursting strength to indicate elasticity is an important factor of bursting strength and float stitch showed higher bursting strength too to indicate that the floating yarn on the surface plays a role of support. 3. As for the relation between knit stitch and air permeability perforated transfer stitch showed the lowest air permeability to prove that the size of perforation affects on the air permeability a great deal. 4. As for the relation between knit stitch and warmth retaining rib stitch through two lined needle bar showed the highest degree. The reason the warmth of perforated transfer stitch didn't decrease much was because the perforation wasn't big enough and content of air increased from the unevenness of the perforated parts through stitch variation. Based upon this result, each stitch can be characteristically summarized as follows; plain stitch showed a stable condition of knit cloth in four kinds of physical property test. And rib stitch is proper to tighten the edge of sleeve or clothe making use of its excellent extension recovery and to make socks for the highest bursting strength and warmth retaining. In the case of transfer stitch, seasonable designs can be taken by controlling the size of loop. Considering the pleasantness, underwear should be made of stitches with good air permeability float stitch was revealed to have color and pattern effects and a great bursting strength. This study has limitations in the aspect that it dealed with a small part of various knit stitches and the items of physical property test were not enough. The author of this study hopes that further studies would make deeper understandings about knit stitch based on more varied stitches and physical property tests ultimately to contribute to the development of fashionable designs proper to maximize the usage, function and originality.

  • 자초(紫草)추출물의 외관상 변색에 영향을 주는 온도와 pH에 대해 조사하였다. 변색은 Hunter치(値)의 차이로 표시 할 수 있으며 자초추출물의 Hunter치(値)는 $50^{\circ}C$ 이상에서 변화하기 시작하고 $60^{\circ}C$ 이상에서는 온도와 상관관계를 이루었다. 온도에 따른 Hunter L, a, b, 치(値)의 변이상관계수는 열처리 시간이 증가함에 따라 감소하였으며, 전체변색의 상관계수는 증가하였다. 66.7% 에탄올로 추출한 추출물을 1시간 열처리 할때 Hunter치(値) 변이 상관계수는 L치(値)의 경우 -0.3696, a치(値)의 경우 -0.4124, b치(値)의 경우 -0.2279, 전체 변색에 있어선 0.5983이었다. 이 때 전체변색의 상관계수는 Hunter L, a, b 각각의 상관계수로부터 직접 계산할 수 있었으며 0.5988로서 거의 비슷한 값을 보여주었다. 한편 pH를 낮추면 Hunter a치(値)는 감도하고 L, b치(値)는 약간 증가하였으나 pH를 증가시키면 pH6.5를 전후로 해서 Hunter L, a, b 치(値) 모두 다 급격히 감소하여 외관상 색깔이 좋지 않았다. 자초(紫草)추출물은 pH가 4.0-6.5일 때 외관상 가장 좋은 '선명한 붉은색'을 나타내었다.

  • We present results of a $H^{13}CN$ J=1-0 mapping survey of molecular clouds toward the Galactic Center (GC) region of $-1.6^{\circ}{\le}{\iota}{\le}2^{\circ}$ and $-0.23^{\circ}{\le}b{\le}0.30^{\circ}$ with 2' grid resolution. The $H^{13}CN$ emissions show similar distribution and velocity structures to those of the $H^{12}CN$ emissions, but are found to better trace the feature saturated with $H^{12}CN$ (1-0). The bright components among multi-components of $H^{12}CN$ line profiles usually appear in the $H^{13}CN$ line while most of the dynamically forbidden, weak $H^{12}CN$ components are seldom detected in the $H^{13}CN$ line. We also present results of other complementary observations in $^{12}CO$ (J=1-0) and $^{13}CO$ (J=1-0) lines to estimate physical quantities of the GC clouds, such as fractional abundance of HCN isotopes and mass of the GC cloud complexes. We confirm that the GC has very rich chemistry. The overall fractional abundance of $H^{12}CN$ and $H^{13}CN$ relative to $H_2$ in the GC region is found to be significantly higher than those of any other regions, such as star forming region and dark cloud. Especially cloud complexes nearer to the GC tend to have various higher abundance of HCN. Total mass of the HCN molecular clouds within $[{\iota}]{\le}6^{\circ}$ is estimated to be ${\~}2 {\times}10^7\;M_{\bigodot}$ using the abundances of HCN isotopes, which is fairly consistent with previous other estimates. Masses of four main complexes in the GC range from a few $10^5$ to ${\~}10^7\;M_{\bigodot}$ All the HCN spectra with multi-components for the four main cloud complexes were investigated to compare the line widths of the complexes. The largest mode (45 km $s^{-1}$) of the FWHM distributions among the complexes is in the Clump 2. The value of the mode tends to be smaller at the farther complexes from the GC.

  • The purpose of this study was to compare GRF characteristics during walking wearing jogging and roller shoes. Twelve male middle school students (age: $15.0{\pm}0.0\;yrs$, height: $173.6{\pm}5.0\;cm$, weight: $587.6{\pm}89.3\;N$) who have no known musculoskeletal disorders were recruited as the subjects. Kinematic data from six S-VHS camcorders(Panasonic AG456, 60 fields/s) and GRF data from two force platform; (AMII OR6-5) were collected while subjects walked wearing roller and jogging shoes in random order at a speed of 1.1 m/s. An event sync unit with a bright LED light was used to synchronize the video and GRF recordings. GRF data were filtered using a 20 Hz low pass Butterworth. digital filter and further normalized to the subject's body weight. For each trial being analyzed, five critical instants and four phases were identified from the recording. Temporal parameters, GRFs, displacement of center of pressure (DCP), and loading and decay rates were determined for each trial. For each dependent variable, paired t-test was performed to test if significant difference existed between shoe conditions (p <.05). Vertical GRFs at heel contact increased and braking forces at the end of initial double limb stance reduced significantly when going from jogging shoe to roller shoe condition. Robbins and Waked (1997) reported that balance and vertical GRF are closely related It seems that the ankle and knee joints are locked in an awkward fashion at the heel contact to compensate for the imbalance. The DCP in the antero-posterior direction for the roller shoe condition was significantly less than the corresponding value for the jogging shoe condition. Because the subjects tried to keep their upper body weight in front of the hip to prevent falling backward, the DCP for the roller shoe condition was restricted The results indicate that walking with roller shoes had little effect on temporal parameters, and loading and decay rates. It seems that there are differences in GRF characteristics between roller shoe and jogging shoe conditions. The differences in GRF pattern may be caused primarily by the altered position of ankle, knee, and center of mass throughout the walking cycle. Future studies should examine muscle activation patterns and joint kinematics during walking with roller shoes.
