Frequency synthesizer is essential structural element of frequency hopping system among bandwidth spread spectrum communication method. And condition of frequency synthesizer in mobile communication machine demand high resolution, wide bandwidth, and high switching speed in order to easily acquire and exchange information of various type. In this thesis a proposed direct digital frequency synthesizer(DDFS) using pipelined accumulator for system-speed and control-inverter instead of conventional look-up table, is designed with 0.8μm design parameter of COMPASS tool and simulated with HSPICE tool. In result, a designed DDFS is superior to in integration and power consumption conventional frequency synthesizer.

The purpose of this study is to understand correctly the personality of the badminton players in boys' high school and to find out good players and train them effectively by developing their specific personality, because personality is a psychological condition for good players. In order to advance the method of training players and obtain fundamental data through understanding properly the character and personality of each player, the survery covering 50 high school badminton players was conducted in three areas from December, 1983 to August, 1984. The findings are such as: 1. When game-history differs; Sociability is highest in the group which has more game-history, while general activity is highest in the one with less history. peculiarly, the impulsiveness placed eighth in the more game-history group is shown second in the less history group. 2. When the role differs; Emotional stability is highest in the regular player group, while sociability is highest in the substitute player group. It is peculiar that dominance placed second in the regular player group is shown at the bottom in the substitute player one. 3. When the training-place differs; Sociability is highest in the group training out of school, while emotional stability is highest in the one training in school. It is peculiar that impulsiveness is shown at the bottom in both groups.

This is a study on the shooting forms of three female players on the top-ranking list of the world archery, who participated in the 9th Asian Games. The purpose of this study is to write a proper prescription for the training of the players' shooting form and its influence upon the record, by making a functional analysis on DAA(Drawing arm Angle), BPA(Bow perpendicular Angle), AHA(Arrow Horizontal Angle), BAA(Bow Arm Angel), RHD(Release Horizontal Distance), RPD(Release Perpendicular Distance), RT(Release Time) and FTT(Follow Through Time) which have a decisive influence upon the shooting form. The outline of this thesis is as follows; 1. DAA The shortest upper-armed BYS's DAA was the biggest and the longest upper-armed KMY's was the least of the three subjects. The arrow group distribution and the record of BYS who had the widest deviation were bad, while those of KMY who had the least deiation and the lowest mean value were good. As the result, the ideal DAA can be said to range from 1°5' to 3°5' 2. BPA BYS' BPA, 3 degree on the average, was the biggest and KJH's, 2 degree, was the least. In the light of the fact that the shortest BYS's BPA was the biggest, is can be inferred that, first, she did ovee drawing, second, the strength of the bow was not suitable for her physical power, third, the choice of arrows was wrong. 3. AHA BYS's AHA, which was 0.1941 degree, was the biggest and the tallest KMY's, 0.017 degree, was the least. Cosequently, AHA can be said to have a close correlation with the height. The AHA of KJH on the top-ranking list of the world archery, was 1.57 degree, the medium of the three subjects and her erroneous difference between shots was 0.01 degree. Furthermore, it seems, that her condition of bow arm and draw arm was good, and the position of nocking point and arrow rest was accurate. Therefore, the position of nocking point and arrow rest can be said to have a great influence upon AHA. 4. BAA The BAA of each subject was analyzed in order to know the most desirable Bow Arm Angle. It was shown that the tallest(166cm) KMY's average was -0.58 degree and the shortest(156cm) BYS's was +0.67 degree. KMY was estimated to maintain the best BAA of the threessubjects, so it might be effective for KJH to lower bow by about 1 degree. 5. RHD The moved distance of the central point of elbow joint at the moment of release was measured in order to know the release style, the umecessary shaking of upper body at the time of release and its subsequent effect on arrow group. As the result, it was in inverse proportion to the height as the shortest BYS's average was 8.9147cm and the tallest KMY's was 6.6722cm. In the release style, the three subjects all together adopted the sliding release. Therefore, it's proved that physically short player with short upper arm has considerable disadvanages at the release. 6. RPD The perpendicularly moved distance of the central point of elbow at the moment of release, was measured. The release style what can be called the last motion in shooting was observed, and the relation of physical condition and RPD was analyzed. 7. RT The time that it would take for the elbow to move as for as RHD was measured and analyzed in order to know the most ideal RT. As the result, it was proved that the concentration, holding and relaxation of the player and her figers pulling the cord at the moment of release were correlative RT is thought to be in proportion to RHD, as BYS with the farthest RHD has also the longest RT. And also it's proved that the release was not done in the state of relaxation because the whole balance of upper body's muscle necessery to release was broken by attempting over drawing in order to induce the same strength as the long upper-armed player. 8. FTT FTT of the subjects in shooting motion was measured and analyzed in order to find out the mutual difference and the most desirable FTT. As the result, it was found out that the three players all together practised Follow Through for too short time Therefore, it's proved that Follow Through over at least 2 seconds is requised to maintain more sufficient time and reflect shooting form through Following Through.

Purpose: The purpose of this study was to investigate the correlation between the visual perception ability and the static dynamic balance ability in health elderly. Method: The Motor Free Visual Perception Test-Row Score(MVPT-RS) and MVPT-Process Time(MVPT-PT) were used for evaluating the visual perception abilities. Assessment of the balance ability was taken by using Good Balance System. In the assessment using Good Balance System, X, Y coordinate speed, anterior-posterior direction, medial-lateral direction and Velocity Movement(VM) in standing posture when eye open were measured as static balance abilities. Thirty-seven healthy elderly who live in Gwangyang participated in the experiment for 2 months, from October to November 2010. Results: 1. There were statistically significant differences of MVPT-RS, MVPT-PT, NSB-X, NSB-Y, NSB-VM, OLB-X, and OLB-VM based on the gender(p<0.05). 2. The negative correlations of MVPT-RS:NSB-Y(r=-0.354), MVPT-RS:OLB-X(r=-0.4), MVPT-RS: OLB-Y(r=-0.371), but positive correlations of MVPT-PT:DTB-T showed a statistical significance(r=0.45, p<0.05). 3. The positive correlations of NSB-X:NSB-Y(r=0.54), NSB-X: NSB-VM(r=0.848), NSB-Y:NSB-VM(r=0.531), OLB-X:OLB-Y(r=0.876), OLB-X:OLB-VM(r=0.872), and OLB-Y:OLB-VM(r=0.787) showed statistical significances(p<0.05). Conclusion: These results showed that the visual perception ability was correlated with some balance ability in health elderly. Especially the perception test process time(MVPT-PT) has closely related with the DTB-T. The visual perception ability is considered as a factor on the balance ability in health elderly. Further study will focus on the development of improving program of visual perception ability as an improving method of balancing ability in health elderly.

미국 역사인류학의 추이와 동향 -미국 인류학의 역사 수용과정을 중심으로-

장용수 한국역사민속학회 2011 역사민속학 Vol.0 No.35

This study intends to introduce the process of taking history into the ‘anthropology without history’ in America. In the late 19th century, American anthropology begins with an evolutionary theory, such as that of Radcliffe-Brown and Malinowski. Boas and his students, historical particularism, have responsibility for leading American anthropologists to field work(participation and observation), neglecting theory building process. Until the mid-20th century, history had not been popular in American anthropology. The appearance of ethnohistory and historical anthropology is the result of realizing importance of history in the understanding of human beings. When a synchronic understanding of human society/culture meets with an obstacle, a diachronic method is in need. Historical method in anthropology contributes our understanding of society/culture to no small degree. Ethnohistory is a historical reconstruction of the society/culture, which has been understood partially. According to Carmack, ethnohistorians study specific history, historical ethnography and folk history, which is classified in accordance with subject matter. As a methodology, ethnohistory is a synthesis of anthropological outcomes. Historical anthropology, influenced by historical sociology, is another synthesis with a large scale perspective. Ethnohistory and historical anthropology render great services to the anthropological aims, the expansion of our understanding of society/culture. 본 연구는 共時的 관점에 머물렀던 초기 미국인류학이 역사를 받아들이는 과정을 소개하는 데 초점을 맞추고 있다. 19세기 후반부터 진화론적 이론으로 무장한 미국인류학은 래드클리프브라운과 말리노우스키와 같은 구조기능주의자들과 현장을 중시하며 문화 상대주의를 강조한 보아스와 그의 제자들을 거치면서 ‘이론 만들기’를 외면하는 경향을 보일뿐만 아니라 역사적인 접근마저도 등한시하게 되었다. 20세기 중반까지도 역사는 미국인류학에서 중요하게 받아들여지지 않다가 민족지학(Ethnohistory)과 역사인류학(Historical anthropology)의 등장으로 인간 이해에 있어서 그 중요성이 부각되었다. 즉, 인간 사회와 문화에 대한 이해에 공시적인 접근방법이 장애를 만났을 때 通時的 방법에 대한 요구가 등장한 것이다. 이에 부흥하듯, 미국인류학에서 역사적인 방법은 사회/문화에 대한 이해에 상당한 공헌을 하게 된다. 민족지학은 한 사회/문화에 대한 단편적인 이해에서 벗어나 전면적인 역사적 재건을 시도한다. 칼맥(Carmack)에 따르면, 민족지학은 역사적 방법을 적극적으로 활용하는 인류학의 한 분야로 주제에 따라 특수한 역사(specific history), 역사적 민족지(historical ethnography), 민속 역사(folk history)로 나눌 수 있다고 한다. 방법론으로서 민족지학은 그 동안의 인류학적 결과물을 종합하는 작업을 수행한다. 미국에서의 역사인류학(Historical anthropology)은 역사사회학의 성공에 영향을 받은 측면이 있는데, 민족지학과 유사하게 인류학적 성과를 종합하지만 거시적인 관점을 보인다는 것이 민족지학이나 유럽의 역사인류학과 다른 특징이다. 민족지학과 역사인류학 모두 역사적 방법을 위주로 인간 사회/문화 이해를 확장함으로써 인간의 총제적인 이해라는 인류학의 목적에 공헌하였다.
