        Redundant 십진코드를 이용하여 십진 자리간 Carry 전파를 제거한 십진 Adder 설계

        諸政玟(Jung-Min Je),鄭台相(Tae-Sang Chung) 대한전기학회 2006 전기학회논문지 D Vol.55 No.11

        In the adder design, reduction of the delay of the carry propagation or ripple is the most important consideration. Previously, it was introduced that, if a redundant number system is adopted, the carry propagation is completely eliminated, with which addition can be done in a constant time, without regarding to the count of the digits of numbers involved in addition. In this paper, a RBCD(Redundant Binary Coded Decimal) is adopted to code 0 to 11, and an efficient and economic carry-free BCD adder is designed.

        건설일용근로자 보호제도의 문제점과 개선방안

        김정훈(Kim Jung-Hun),이승욱(Lee Seung-Wook),정태상(Jung Tae-Sang),김용수(Kim Yong-Su) 대한건축학회 2009 大韓建築學會論文集 : 構造系 Vol.25 No.1

        The purpose of this study is to analysis the problems of the protect system which is for day-to-day construction workers, and to propose the improvement plan. For the purpose of this study, grasp the working condition through a case study and make an examination of day-to-day construction workers employed management in a construction sites. Also it propose the improvement plan, about the problem of day-to-day construction worker's protect system by the Labor Standard Act and Labor related laws. Following these studies, derived the problems of current labor related laws including the labor standard act and propose the improvement. The results of this study were as follows; 1) Labor related laws as the Labor Standard Act is not be suited day-to-day construction workers Analyze the problems of protecting day-to-day construction worker's protect system. And have a problem whit employment business as well as payment level and method of a retiring allowance. 2) Based on analyzed problems, Propose the improvements plan for reinforcing the function of protecting construction laborers laws, unifying the employment management system and severance exemption system. And the I type of retiring allowance payment method becomes to S type what is according to record of a company.

        사격선수들의 심리훈련프로그램 적용에 따른 경쟁상태불안, 심상유형 및 심리기술과의 관계

        송은섭(Song, Eun-Sub),정태상(Jung, Tae-Sang),최덕환(Choi, Deok-Hwan) 한국체육과학회 2012 한국체육과학회지 Vol.21 No.6

        The purpose of this study is to find out the relationship among competition state anxiety, imagery types and psychological skills of middle and high school shooting athletes applied to the psychological training program for twelve weeks. This study has been applied to total 180 middle and high school shooting athletes of 90 men and 90 women who represent Seoul, Incheon and Chungcheongnam-do province with ultimate total of 177 athletes consisting of 89 men and 88 women. The used statistical methods for the data analysis were frequency analysis, reliability analysis, correlation analysis, weight estimation regression analysis by using SPSS 16.0 program. The results were as followings. First, competition state anxiety had a significant effect on imagery types. Second, competition state anxiety had a significant effect on psychological skills. Third, imagery types had a significant effect on psychological skills.

        슬관절 굴곡력강화운동프로그램 적용에 따른 인라인 롤러스피드스케이팅 선수의 슬관절 근기능 변화

        박동훈(Park, Dong-Hoon),장지훈(Jang, Jee-Hun),유호(Yoo, Ho),정태상(Jung, Tae-Sang) 한국체육과학회 2012 한국체육과학회지 Vol.21 No.1

        The purpose of this study was to identify the changes of muscular function in the knee joint after application of knee flexor strengthening program(KFSP) during 12-week-winter training period, and to present the basal data for development of muscular strengthening program for prevention of injury and improvement of athletic performance. Participants were 15 male in-line roller speed skaters, and assigned to middle school group(MI, n-S) and university group(UN, n=7). KFSP was applied to both groups for 12 weeks, 4 times per week, 23~36 minutes per day. Muscular function in the knee joint was repeatedly measured with isokinetic dynamometer before and after application of KFSP. As a result, all muscle strength and power related variables except dominant-side flexion peak torque were tended to be decreased in MI. In UN, all muscle strength and power related variables were tended to be increased. Dominant-side flexion peak torque and average power, and dominant-side ipsilateral balance ratio were significantly increased(p<.01) in post-test. All muscle endurance related variables in both groups showed the positive changing tendency. Dominant-side extension and flexion fatigue index were significantly decreased(P<.05) in post-test. In conclusion, KFSP in this study was effective in the improvement of muscular function and ipsilateral balance ratio in UN. And it is suggested that KFSP after puberty should be more effective than that during puberty. Ipsilateral balance ratio in pre-test suggested that intervention program for prevention of sports injury in in-line roller speed skaters should be introduced.
