안진영,강윤정,김상준,An, Jin-Young,Kang, Yun-Jeong,Kim, Sang-Choon 한국정보통신학회 2009 한국정보통신학회논문지 Vol.13 No.10

본 논문에서는 다중입력 다중출력 (Multiple Input Multiple Output: MIMO) 시스템에서 Maximum Likelihood (ML) 수신기와 같은 성능을 가지지만 복잡도가 낮은 Sphere Decoding (SD) 알고리즘에 대해 분석하고 그 성능을 평가한다. 각각의 송신 안테나에서 채널로 전송되는 독립적인 신호는 QPSK 와 16QAM 방식을 사용하여 변조되며, 채널은 산란이 활발하게 일어나는 레일리 (Rayleigh) 평탄 페이딩 채널로 가정한다. 수신기에서 수신된 신호는 Fincke & Pohst SD 알고리즘에 의해 각 송신 안테나로부터의 독립적인 신호로 검파되며, 그 성능이 ZF (Zero Forcing), MMSE (Minimum Mean Square Error), SIC (Successive Interference Cancelation), 그리고 ML 수신기의 성능과 비교되었다. 추가적으로 복잡도를 줄이기 위해 개선된 형태인 Viterbo & Boutros SD 알고리즘을 이용하여 검파된 신호의 BER 성능과 부동 소수점 연산량(Floating Point Operations: FLOPS)이 각각 비교 분석되었다. In this paper, we analyze the performance of the sphere decoding algorithm at MIMO system. The BER performance of this algorithm is the same as that of ML receiver, but computational complexity of SD algorithm is much less than that of ML receiver. The independent signals from each transmit antennas are modulated by using the QPSK and 16QAM modulation in the richly scattered Rayleigh flat-fading channel. The received signals from each receivers is independently detected by the receiver using Fincke & Pohst SD algorithm, and the BER output of the algorithm is compared with those of ZF, MMSE, SIC, and ML receivers. We also investigate the Viterbo & Boutros SD algorithm which is the modified SD algorithm, and the BER performance and the floting point operations of the algorithms are comparatively studied.

The Rhus verniciflua Stokes (乾漆-RVS) has been used in traditional East Asia medicine for the therapy of gastritis, stomach cancer, although the mechanism for the biological activity is unclear. In the present study aims to investigate RVS extract contributes to growth inhibitory effect and it's the molecular mechanism on the human gastric cancer cells. AGS (gastric cancer cells) and RIEI (normal cells) were treated to different concentrations and periods of RVS extract $(10{\;}{\sim{{\;}100{\;}ug/mil)$. Growth inhibitory effect was analyzed by measuring FACS study and MTS assay. Cell cycle inhibition was confirmed by measuring CDK2 kinase activity by immunoprecipitation and kinase assay. And apoptosis was confirmed by surveying caspase cascades activation using a pan caspase inhibitor Exposure to RVS extract (50 ug/mll) resulted in a synergistic inhibitory effect on cell growth in AGS cells. Growth inhibition was related with the inhibition of proliferation and induction of apoptosis. The extract induces Gl -cell cycle arrest through the regulation of cyclins, the induction of p27kip1, and the decrease CDK2 kinase activity. And upregulated p27kip1 level is caused by protein stability increment by the reduction of S-phase kinase-associated protein 2 (Skp2), a key molecule related with p27kip1 ubiquitination and degradation, and do novo protein synthesis. Besides, 乾漆 extract induces apoptosis through the expression of Bax, poly(ADP-ribose) polymerase (PARP) and activation of caspase-3. RVS extract induces Gl -cell cycle arrest via accumulation of p27kip1 and apoptosis in human gastric cancer cells but not in normal cells, therefore we suggest that the extract can be used as a novel class of anti-cancer drugs.

태권도 품새경기규칙 개정에 따른 선수인식과 발전방향

안진영,김두한,안근아 한국스포츠학회 2011 한국스포츠학회지 Vol.9 No.4

The objective of this study is to focus on the influence of the rules of the Taekwondo Poomsae competition on the athletes’ awareness and suggest the developmental direction for the Poomsae competition, in order to help not only those practicing Taekwondo but also the general public to recognize the value of the Taekwondo Poomsae competition as a martial-art sport from now on. The results of this study can be drawn as follows. Firstly, this study has focused on changes related to the athletes’ training and responses in a competition based on the amendment of the rule about the distribution of marks according to the marking standard of the Poomsae competition. The distribution of marks used to be based on the ratios of 5 : 3 : 2 in the order of accuracy, skillfulness and expressivity. However, the ratios have been changed to 3 : 4 : 3, influencing the athletes’ awareness. Since referees greatly focus on such factors as skillfulness and expressivity according to the marking standard, athletes’ attitudes and awareness towards the training or competition have been changed. Secondly, it is necessary to apply more objective rules of the competition in order to make it possible to clearly distinguish victory from defeat. Since the current rules still provide vague explanation and standard points regarding accuracy, skillfulness and expressivity, it is necessary to establish simpler rules of the competition which could be used to easily distinguish victory from defeat from now on. Since Taekwondo is a martial-art sport, it is necessary to establish new rules of the competition for the athletes participating in the Poomsae competition to follow, in order to make them thoroughly train themselves by practicing all the basic skills. By following such a way, it would be possible for them to make themselves become truly devoted to Taekwondo and equipped with the right kind of basic knowledge and Taekwondo spirit.

안진영,안근아 한국스포츠학회 2017 한국스포츠학회지 Vol.15 No.4

이 연구는 대학 태권도 품새선수의 운동중도탈락에 관한 내용을 살펴보는데 그 목적이 있었으며, 결론은 다음과 같다. 첫째, 대학 태권도 품새선수들은 대부분 각 지역별 품새 전문 태권도장에서 선수생활을 시작하였다. 현재 태권도 품새종목을 육성하는 학교선수단의 활성화가 미흡하기 때문에 주로 태권도장 소속으로 훈련과 시합출전이 이루어지고 있었다. 둘째, 대학 태권도 품새선수의 대학 입학 이후 목표는 국가대표 선수를 희망하는 경우가 많았다. 현재 대학 품새선수들의 한정적인 진로의 폭을 개선하기 위하여 태권도 품새의 전국체전 도입 및 실업팀 활성화가 반드시 요구된다. 셋째, 대학 태권도 품새선수 활동은 대체적으로 자율적인 분위기, 주장체제로 운영되고 있었다. 대학 태권도 품새선수들이 경기력에만 집중할 수 있는 시스템이 마련되어야 할 것이다. 넷째, 대학 태권도 품새선수 운동중도탈락의 원인에는 최근 도입된 새품새와 자유품새의 다양한 발차기 기술과 아크바틱 동작의 어려움, 입상혜택의 미흡함 등이 있었다. 다섯째, 태권도 품새 전공자들의 다양한 직업군의 정보공유와 진로탐색을 위해 태권도 품새와 관련된 진로 가이드라인 구축이 요구된다. The purpose of this study was to investigate the content of drop-out among college Taekwondo Poomsae players. The findings were as follows: first, most of college Taekwondo Poomsae players started their careers as a player at a Taekwondo studio specializing in Poomsae in each area. As the activation of Taekwondo Poomsae teams was currently poor in schools, they participated in training and entered a competition, being affiliated usually with a Taekwondo studio. Second, many of the players set a goal of joining the national team after being admitted to college. It is required to introduce the Taekwondo Poomsae category in the National Sports Festival and vitalize business Taekwondo Poomsae teams to improve the current limited career paths for college Poomsae players. Third, their activities were run in a mostly autonomous atmosphere under the team leader system. A system should be established to help college Taekwondo Poomsae players concentrate only on their performance. Fourth, the causes of their drop-out included the difficulty of various kicking techniques and acrobatic movements recently introduced in the New and Free Style Poomsae and the insufficient award benefits. Finally, a career guideline should be set in relation to Taekwondo Poomsae to help Taekwondo Poomsae majors share information and explore career options among various occupational clusters.
