Jun Ho Kim, Eun Sun Jung, Chul-Hyun Kim, Hyeon Youn and Hwa Rye Kim. Genetic associations of body composition, flexibilityand injury risk with ACE, ACTN3and COL5A1polymorphisms in Korean ballerinas. JENB., Vol. 18, No. 2, pp.205-214, 2014[Purpose] The purpose of this study was to exam the association of body composition, flexibility, and injury risk to genetic polymorphismsincluding ACEID, ACTN3RX, and COL5A1polymorphisms in ballet dancers in Korea. [Methods]For the purpose of this study,elite ballerinas (n = 97) and normal female adults (n = 203) aged 18 to 39 were recruited and these participants were tested forbody weight, height, body fat, fat free mass, flexibility, injury risks on the joints and gene polymorphisms (ACE, ACTN3, COL5A1polymorphism). [Results]As results, the ACEDD genotype in ballerinas was associated with higher body fat and percentageof body fat than the ACEII and ID genotypes (p< 0.05). In the study on the ACTN3polymorphism and ballerinas, the XXgenotype in ballerinas had lower body weight and lower fat-free mass than the RR and RX genotype (p < 0.005). Also, the meansof sit and reach test for flexibility was lower in the ACTN3XX genotype of ballerinas than the RR and RX genotype of ballerinas(p< 0.05). Among the sports injuries, the ankle injury of the XX-genotyped ballerinas was in significantly more prevalence thanthe RR and XX-genotyped ballerinas (p< 0.05). According to the odd ratio analysis, XX-genotyped ballerinas have the injuryrisk on the ankle about 4.7 (95% CI: 1.6~13.4, p< 0.05) times more than the RR and RX-genotyped ballerinas. Meanwhile, theCOL5A1polymorphism in ballerinas has no association with any factors including flexibility and injury risks. [Conclusion]Inconclusion, ACEpolymorphism and ACTN3polymorphism were associated with ballerinas` performance capacity; COL5A1wasnot associated with any factors of performance of Ballerinas. The results suggested that the ACEDD genotype is associated withhigh body fat, the ACTN3XX genotype is associated with low fat-free mass, low flexibility, and higher risk of ankle-joint injury.

水分 및 Diesel oil의 供給에 의한 Gasoline Engine의 CO 減少에 관한 硏究

全哲昊 동아대학교 공과대학 부설 한국자원개발연구소 1979 硏究報告 Vol.4 No.1

This paper is about the study on the decreasing emission of carbon monoxide by supercharging waterdrop and diesel oil in a gasoline engine. The results of the experiment were as follows. 1. Carbon monoxide was decreased as the ratio of air-fuel mixture went higher, but there was a misfire as it was over 18. 2. When waterdrop and diesel oil were supercharged, carbon monoxide was much more decreased than in the natural condition. 3. As the injection pressure want higher, carbon monoxide was decreased.

전철호,장길홍 동아대학교 공과대학 부설 한국자원개발연구소 1993 硏究報告 Vol.17 No.2

The use of a combined cycle leads to an updating of power output, at the same time, increasing power plant efficiency. In this paper, the dissipation energy was calculated from two conventional and combined cycle processes, and then the efficiencies of many types of the combined cycle were compared. The efficiency of combined cycle power plant is evaluated by given data and its performance characteristics from the simulation. As a result, the total efficiency is increased as the compression ratio is increased.

全哲昊,徐海成 동아대학교 공과대학 부설 한국자원개발연구소 1989 硏究報告 Vol.13 No.2

Heat transfer charcteristics at the internally finned condenser and in case of no finned condenser in rotating heat pipe been numerically and experimentally studied. The results of numerical and experimental showed good agreement and it was able to predict to the performance of a rotating heat pipes. Heat transfer ratio of a internally finned condenser and no finned condenser was increased largely by increasing fin numbers but it had no influenced upon changing fin half angle and fin height. By decreasing condenser radius and increasing saturation temperature, heat transfer ration was rapidly increased.

C. fetus 심내막염은 드물게 발생하는 질환으로 주로 면역능이 저하된 환자에서 발병하고 대동맥판을 침범하는 경우가 많으며 적절한 치료가 되지 않을 경우 치사율이 높다. 저자들은 기저질환이 없던 69세 남자에서 C. fetus 심내막염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 발열로 내원하여 시행한 혈액배양 검사상 C. fetus가 동정되었고 경식도 초음파 검사상 삼첨판에 증식증이 발견되어 심내막염 진단하에 ceftriaxone에 이어 meropenem으로 총 4주간 항생제를 투여받고 호전되었다가 한달 후 다시 재발하였고 판막부전 소견 진행하여 삼첨판 치환술을 시행받고 전신상태 호전되어 퇴원하였다. Campylobacter fetus is a rare cause of endocarditis. To date, only about 30 cases of C. fetus endocarditis have been reported mainly in the elderly with chronic underlying illnesses. Most cases showed tendency to involve aortic valve. This report describes a case of native tricuspid valve infective endocarditis in a 69-year-old man without any underlying disease. Despite adequate antibiotic therapy for 4-weeks, endocarditis recurred and leading to surgical valve replacement.

全哲昊,徐海成 동아대학교 공과대학 부설 한국자원개발연구소 1985 硏究報告 Vol.9 No.1

Cu heat pipe with SiO₂ sintered wicks type capillary structure and distilled water as the working fluid was studied in the heat transfer rate range of 60W to 180W. Analysis resistances are considered in the pipe wall at the condenser and evaporator, in the fluid gap between pipe wall and capillary structure, at liquid vapor interface, and in the vapor region. The results are as follows. 1) Thermal resistance of wick had larger than any other thermal resistance and thermal resistance at pipe wall, interface, vapor region can usually be neglected 2) Increase the heat transfer rate and vapor temperature, temperature difference of evaporator were increased but temperature difference of vapor path were not changed.

신인철,어진우,강호준 단국대학교 1997 論文集 Vol.31 No.-

Image compression techniques have been necessary to transfer and save a great amount of image data in an efficient way. Because the compression and decompression of image signal require the real time processing, various hardware implementation methods have been studied. In this paper we propose the algorithm which is parallel form of processing 2 dimensional 8*8 blocks simultaneously, so increase speeds. It outputs compressed bit sequences 8 clocks later for the input data synchronized to clocks. Proposed algorithm is designed using VHDL. Simulation and circuit synthesis has been performed by the Powerview CAD Tool on the SUN Sparc-10 workstation. Results shows that maximum operating frequency is up to 15㎒. The final schematic circuit and comparison of processing speed are shown.

Bi□Sr□Ca(Cu□-□Ni□)□O□+δ (x=0, 0.003) 단결정을 개선된 방향성 응고법을 이용하여 성장시켰으며, 표준 4단자법으로 ab-면의 비저항을 측정하였고, Direct four-probe법을 이용해서 c-축의 비저항을 측정하였다. Arrhenius plot slopes의 기울기는 활성화 에너지를 나타내는데 이의 온도 의존성에 대하여 조사하였다. 자기장을 인가하여 활성화 에너지를 측정하면, 고온과 저온에 서로 다른 두개의 TAFF 영역이 나타나는 것을 볼 수 있고, 이들 활성화에너지는 고온 영역에서는 lnB에 비례하고, 저온 영역에서는 B□□ 에 비례하였다. By making use of the improved directional solidification method and, standard and direct four-prove methods respectively. We grow Bi□Sr□Ca(Cu1-□Ni□)2O8+δ (x=0, 0.003) single crystal and measure its resitivities in ab-plane and c-axis. The temperature at the activation energy, which is described by a slope in the Arrhenius plot, is examined. The activation energy measured by applying the external magnetic field, exhibits two different TAFF regimes at low and high temperatures. It is shown that the activation energy is propotional to lnB and B□□ at high and low temperature regimes, respectively.
