Shin, S-H · Lim, Y-T · Kim, T-H · Park, K-J and Kwon, M-S. Electromyographical Analysis of Muscle Activities of Upper Trunk for Ssireum Dutguri Technique. Korean Journal of Sport Biomechanics, Vol. 13, no. 1, pp. 95-108. The purposes of this study were to analyze the muscle activities and the characteristics of muscle recruiting patterns of upper trunk for Ssirum dutguri technique using three top-ranked elite Ssirum players. The EMG technique was used to record muscle activities of both right and left sides of latissimus dorsi, biceps brachii, and erector spinae. Six surface electrodes were placed on the surface of the selected muscles and one ground electrode was also attached on the back of neck(C7). One video camera was also used to record the Ssirum motion to define 4 events and 3 phases for further analysis. The raw EMG data were filtered with band pass filter (50-400 Hz) to remove artifacts and then low pass filtered (4 Hz) to find the linear envelope which resemble muscle tension curve. This filtered EMG data were normalized to MVIC for the purpose of comparion between the subjects. The results were indicated that each subject with different physical characteristics showed very different muscle activity patterns. Although Ssirum dutguri is considered as foot technique the player grasped opponent's satba(belt) with both hands when they play. Because of this reason, activities of upper trunk muscles were relatively high. However, direct comparison between upper and lower body muscles was not possible due to the lack of the data in present study. Interestingly, all threes subjects showed that erector spinae muscle activity was comparatively higher than those of latissimus dorsi and biceps brachii. This implies to reinforce back muscle as a routine of training to improve performance or to prevent back injury. implies to reinforce back muscle as a routine of training to improve performance or to prevent back injury.

신수철,조태환 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.5

에틸렌디아민을 용매로 하여 용매열합성으로 200℃에서 1-5시간 반응시킨 후 1,000℃에서 1,400℃로 2-4시간 동안 대기중에서 열처리 과정으로 Eu가 도핑 된 Y₂O₃ 나노 입자를 제조하였다. 1,000℃에서 2시간 동안 열처리한 결정의 X선 회절패턴은 보고 된 데이터(JCPDS 카드파일 41-1105, a=10.60418 Å)와 거의 일치하는 격자상수 a=10.6029 Å인 순수한 큐빅상의 Y₂O₃을 나타내었다. 제조된 형광체의 평균입자 크기는 대략 100 nm로 구형의 형태를 가진다. 열처리 온도가 증가함에 따라 형광체 입자의 크기가 감소하였으며, 또한 형광체의 발광 세기가 증가하였다. PL 스펙트럼 분석 결과, Eu의 농도가 3% 도핑 된 Y_(2-x)O₃:Eu^(3+)_(x) (x=0.06) 형광체는 250 nm파장에서 여기 스펙트럼을 나타내었고, 611 nm 파장에서 주발광 스펙트럼을 나타내었다. Eu doped Y₂O₃ nanoparticles were prepared with the solvothemal synthesis using ethylenediamine solvent at 200℃ for 1-5 h and then annealed in air at from 1,000℃ to 1,400 for 2 4 h. The X-ray diffraction pattern of the crystals annealed at 1,000℃ for 2 h could be indexed as pure cubic cell of Y₂O₃ with the lattice parameter a=10.6029 Å which is very close to the reported value (JCPDS Card File 41-1105, a=10.6041 Å). Average sizes of prepared phosphor particles had about 100 nm, size and spherical morphology. The phosphor panicle size decreased and the emission intensity increased as the annealing temperature increased. Through PL spectrum analysis, the 3% Eu doped Y_(2-x)O₃:Eu_(x)^(3+)(x=0.06) phosphor showed the excitation spectrum at 250 nm wavelength and the maximum emission spectrum appeared at 611nm wavelength.

진행성 골화성 섬유 이형성증은 2 백만명 중에 1명 발생하는 매우 드문 유전질환이다. 저자들은 2차례의 외상후 심해진 진행성 섬유 이형성증환자에서 최근 다시 발생된 외상후 생긴 병변부위에 biphosphonate와 steroid 투여로 최근수상부위의 근육 골화와 경화를 현저한 호전을 보였으나, 기존의 골화가 이미 진행된 병변에서는 잘 반응하지 않음을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Fibrodysplasia ossificans progressiva(FOP) is an extremely rare hereditary disorder characterised by progressive heterotopic ossification of the soft tissue. The resulting progressive immobilization of the limbs, jaw and chest wall generally leads to severe disability. We present an 20-rear-old man with advanced FOP. He had two operative interventions by prior traffic accident and recent biopsy. It resulted abnormal ossification. Treatment for this disorder is avoidance of exacerbating factors and medical strategies is biphosphonate and steroid. We observed the course of ossification and muscle atrophy during biphosphonate and steroid therapy in advanced FOP.

T. Y. SHIM, S. H. SHIN, S. I. OH, J. I-. MUN. EMG Analysis for Investigation Muscle-Collaborated Relationship during Golf Swing. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 177-189, 2004. Kinematic and kinetic analysis using 3D Motion Capture system are common, yet there is little in the literature that discuss the relationship and coactivity between muscles during the golf swing. The purpose of this study was to describe the relationship between the employed 16 muscles during golf swing. We could observe 3 muscle patterns such as 'Line' shape, 'L' shape, and 'Loop' shape for the golf swing activity. The 'Line' shape indicates that two muscles act almost perfectly in phase, and the 'L' shape represents that two muscles act in a reciprocating manner(When one is active, the other is quiescent and vice versa). And the 'Loop' shape indicates that two muscles act sequently(After one is active, the other act). In these results, we knew the muscle patterns during golf swing is similar to the patterns during gait. And we presented it was possible to show the consistence of golf swing through the frequency analysis of muscle patterns. We believe that the results potentially useful for the golf players and coaches to analyze their performance.

Converting of wasted plastics into oil can be used as a new energy source. It has advantages of reducing the environmental problems and produces additional economic values. In this study, polyethylene and polypropylene were catalytically degraded by JSA-1(Si/Al=6.7), JSA-2 (Si/Al=2.57), HZSM-5 (Si/Al=30.2) and MCM-48(Si/Al=100/0) catalysts to investigate the optimum degradation conditions. The order in liquid product yield was JSA-2 > JSA-1 > HZSM-5. Liquid product yield was increased with the catalyst loading, but the carbon number distribution of the liquid product was widely spreaded. When the HZSM-5 was phosphated to regulate the acidity, the liquid product yield was in the order of P (2 wt %) HZSM-5 > P (1 wt %) HZSM-5 > HZSM-5 > P (3 wt %) HZSM-5. The optimum acidic amount and strength of the phosphated HZSM-5 was achieved when 2 wt % P was loaded. It was confirmed by the ammonia TPD. HMCM-48 with acid sites was not blocked by carbon deposition because of the large pore size. So, it seems to promote the catalytic activity of the plastic degradation.

김동환,신태균,김무강,김홍선,김원식 충남대학교 의과대학 지역사회의학연구소 1989 충남의대잡지 Vol.16 No.1

In order to study the morphological changes of Corti’s organ in the rat treated with cisplatin and tobramycin, thirty-three rats, weighing between 200∼250g, were used, and divided into 4 groups, i.e., 3 rats were used for control, and 30 rats were used for 3 experimental groups. Each experimental group was divided into cisplatin-treated, tobramycin-treated, and both cisplatin and tobramycin treated group with 10 rats. Rats were injected with a single dose of 7.7㎎/㎏ of cisplatin intraperitoneally and 50㎎/㎏/day of tobramycin for 2 days intramuscularly, respectively or both. Treated rats were sacrificed on the 3rd and 5th day after the first injection. Results were as follows; 1. Cisplatin-treated group: Outer hair cells of Corti’s organ were degenerated with the formation of vacuoles and appearance of lysosomes, however, inner hair cells showed mild vacuolization. 2. Tobramycin-treated group: NO pathological changes were found in Corti’s organ. 3. Combined cisplatin and tobramycin treated group: Outer and inner hair cells showed vacuolization, appearance of lysosomes, myelin figures and multivesicular body. There were also multivesicular body in the inner phalangeal cell and myelin figure in the Reissner’s membrance. 4. Degeneration of Corti’s organ in the combined treated group was more sever than those of the single cisplatin-treated or tobramycin-treated group. 5. NO pathological differences of Corti’s organ in duration of postinjection were manifested in any groups. It can be concluded that cisplatin induces toxicity to inner ear and cisplatin enhance toxicity more in continued treated with tobramycin.
