Language has stronger binding force than the legal code as a norm, and its impact on civil life is very great, but neither civil participation nor democratic control has been made in the enactment and revision of language-related norms. And it was outside the attention of normative science researchers including legal researchers, and progressive activists. Looking at the linguistic phenomena that have recently emerged prominently in our society, one can see that language is used as a tool of labor control and an ideological tool for acquiring and expanding political power. Terms such as the 52-hour workweek, Ballyeodongmul(companion animals) and Bihon(non-marriage) are good examples. On the other hand, Korean is experiencing a phenomenon in which regional languages are gradually disappearing. This phenomenon shows a negative tendency to eliminate cultural diversity, enhance uniformity, and strengthen social standing along with the concentration of the metropolitan area. Moreover, the influx of Japanese and Western languages is rapidly destroying and replacing the unique forms and structures of the Korean language. Language is an organic social norm system, and it is inevitable that it changes with social change. However, since our language is subject to state control and regulation rather than natural changes resulting from such social changes, we use language regulated by the state, not natural language. The state's language control does not simply mean the existence of language norms controlled by state agencies. The compulsory power of language norms is achieved through the control of the mass media and educational institutions. Although the state has given up direct control over specific educational contents or broadcasting or news coverage, it is still able to control our ideas and ideologies by regulating the language as the form of conveying them. While the normative nature of language is in some respects that language itself is a kind of social norm, it can also be emphasized that the existence of norms for language is essential. Therefore, the enactment and revision of language norms should be carried out through citizen participation and democratic control, and should be made in a way that can contribute to the maintenance and development of the uniqueness of Korean and its regional languages. 언어는 규범으로서 법규범보다 더 강한 구속력을 지니고 있으며, 시민생활에 미치는 영향도 매우 크지만, 언어에 관한 규범의 제ㆍ개정과정에 시민의 참여나 민주적 통제는 이루어지지 않았으며, 법학을 비롯한 규범학 연구자들이나 진보적 활동가들의 관심밖에 있었다. 최근 우리 사회에서 두드러지게 나타나는 언어현상들을 보면 노동을 통제하고 지배하기 위한 도구로서, 정치권력의 획득과 확대를 위한 이데올로기적 도구로서 언어가 동원되고 있음을 알 수 있다. 주 52시간 노동제나 반려동물, 비혼과 같은 용어들이 그 실례이다. 다른 한편으로 우리말은 점진적인 지역언어 소멸이라는 현상을 겪고 있으며, 이와 같은 현상은 서울을 중심으로 한 수도권 집중현상뿐만 아니라 문화적 다양성의 말살과 획일성의 증대, 사회적 서열의 강화라는 부정적인 경향을 보이고 있다. 아울러 일본어와 서구언어의 유입은 한국어 고유의 형태와 구조를 급속히 파괴하고 이를 대체하고 있는 실정이다. 언어는 유기적인 사회규범 체제로서 사회변화에 따라 변화하는 것은 필연적인 현상이라고 할 수 있다. 그렇지만 우리말은 이와 같은 사회적 변화에 따른 자연적인 변화보다는 국가에 의한 통제와 규제의 대상이 된 까닭에 우리는 자연적 언어가 아니라 국가에 의해 규제된 언어를 사용하게 된다. 국가의 언어통제는 단순히 국가기관에 의해 통제되는 언어규범의 존재만을 의미하는 것은 아니다. 언어규범의 강제력은 교육기관과 방송 등의 대중매체에 대한 통제를 통해 이루어진다. 국가는 구체적인 교육내용이나 방송ㆍ보도에 대한 직접적 통제를 단념하였지만, 그 내용을 전달하는 형식으로서의 언어를 규제함으로써 사회통제 내지는 통합의 이데올로기를 표출하고 나아가 사상과 이념을 제어할 수 있게 되었다. 언어의 규범적 속성은 언어 자체가 일종의 사회규범이라는 측면도 있지만, 언어에 대한 규범의 존재가 필수적으로 요구되고 있다는 측면도 강조될 수 있다. 그렇기에 언어규범의 제ㆍ개정과정은 시민의 참여와 민주적 통제를 거쳐 이루어져야 하며, 지역언어와 우리말의 고유성을 유지ㆍ보전하고 발전하는 데 이바지할 수 있는 방향으로 이루어져야 한다.

The purpose of this study was to analyze the preference of leader behavior styles according to the trait of soccer players. The trait of soccer players was characterized by age, career of winning a prize, birth order. The classified five behavior styles were training and instruction behavior, democratic behavior, autocratic behavior, social support behavior and positiv feedback behavior in the multidimensional model introduced by Chelladurai and Saleh(1980). Total of 286 soccer players were answered to the questionnaire. All subjects were registered players at the federation of soccer and attended national tournament more than once. The findings of this study were as follows: 1) In the preference of leader behavior style among the soccer players, training and instruction behavior was the most perceived behavior style. Democratic behavior, Positive feedback behavior, and social support behavior were preferred to be of second, third and fourth respectively. Autocratic behavior was the least preferred leader behavior style. 2) In the difference of leader behavior style according to the age of soccer players, middle school team preferred more than pro team in the training and instruction behavior, democratic behavior, and positive feedback behavior. 3) No significant difference was found according to the career of winning a prize and birth order of soccer players in the preference of leader behavior styles.

이용인,김승환,탁민제 한국항공우주학회 2012 한국항공우주학회 학술발표회 논문집 Vol.2012 No.11

본 논문에서 임의의 유도상수를 갖는 일반화된 충돌각 제어 유도법칙을 제안한다. 표적이 정지되어있고 유도탄 동특성을 무시하며 비행경로각이 작다는 가정 하에 제안한 유도법칙의 폐루프 해석해를 구하고 이를 통해 종말구속조건인 유도오차와 충돌각을 만족시키기 위한 유도상수의 필요조건을 도출한다. 제안한 유도법칙의 실제 적용을 위해 유도상수에 따른 궤적 특성을 고려한 잔여비행시간 계산 방법을 기술한다. 또한 역최적제어 기법을 이용하여 제안한 유도법칙의 최적성을 규명하고 유도상수와 성능지수와의 상관관계를 제시한다. 마지막으로 모의시험을 통하여 유도기하의 비선형 특성과 유도탄 동특성에 따른 비행성능을 검토한다. In this paper, a generalized guidance law with an arbitrary pair of guidance coefficients for impact angle control is proposed. Under the assumptions of a stationary target, a lag-free missile with constant speed, and small path angle, necessary conditions for the guidance coefficients to satisfy the required terminal constraints are obtained by deriving explicit closed-form solutions. In order to implement the guidance law, a practical time-to-go estimation method for the generalized guidance law is proposed by considering the curved-path depending on the guidance coefficients. By solving an inverse optimal control problem, moreover, it is found that the proposed guidance law can minimize a certain performance index. The relationship between the guidance coefficients and the corresponding quadratic performance index is explicitly investigated as well. Finally, performance degradation due to nonlinearity and system dynamics is examined through simulations.

李勇仁 충남대학교 자연과학연구소 1981 忠南科學硏究誌 Vol.8 No.2

A total of 50 students of the physical education department in Chungnam National University who had been trained in gymnastics for over a year, were studied about their Kinesthetic sense (position sense of body 45° and 135°) and its relation with motion of handspring and front somersault in order to examine the theoredical correlationships among kinestiletic sense and gymnastic motions. 1. In case of degree 45° position sense of body. It was found that significant correlationships of kinesthetic sense with handspring and front somersault were found with r=-0.44 and r=-0.42 respectively. 2. In case of degree l35°position sense of body. It was found that significant correlationships of kinesthetic sense with handspring and front somersault were found with r=-0.30, r=-0.28.

이용인,박응철 충남대학교 체육과학연구소 2000 體育科學硏究誌 Vol.18 No.1

For this study I gave my students a task "Turning forward after putting hands on a mat." The purpose of my research is to find out "effects which the confidence in the task has on their performance result and attribution factors." The summary of my research is the following: 1. Accomplishment level depending on the confidence in motor performance To find out the difference of accomplishment level, the students were divided into three groups on accordance with the test result of confidence. The high level students were 46, the middle level students, 125, and the low level students, 38. The average score of the high level students was 109.65, that of the middle level students, 74.67 and that of the low level students was 38.71. That result shows high correlation between confidence and performance. So a teacher's encouragement for his students to strengthen their confidence will lift up the accomplishment level in motor performance of the students. 2. Accomplishment level depending on success or failure of a performance To find out effects the success or the failure of a performance has on accomplishment level, student; were divided into two groups; a success group and a failure group. The result is that the accomplishment level of the success group is higher than that of the failure group. This means teacher's proper guidance for students' success in performance will bring an elevation of the students' accomplishment level. 3. Attribution factors which has effects on the success group The following is the analysis of attribution factors which has effects on the confidence of the success group: The relative difficulty of a task has little effect on the three groups which have different confidence in the success group of the performance. The students' effort to the task are different between the high level group of confidence and the middle level group of confidence, also between thee high level group of confidence and the low level group of confidence. But there is no difference between the middle level group of confidence and the low level group of confidence. The difference of the students' ability is the following: There is difference between the high Bevel group of confidence and the low level group of confidence, also between the middle level group of confidence and the low level group of confidence. But there is no difference between the high level group of confidence and the middle level group of confidence. Fortune has no effect on all the three groups. 4. Attribution factors which has effects on the confidence of the failure group The relative difficulty of a task has little effect on the three groups which have difference in the success group of the performance. The student's efforts to the task are not different from the three groups. The studens' ability is not different from the three groups. Fortune has on effect on all the three groups. In conclusion, all attribution factors - relative difficulty of a task, effort, ability and fortune - has no effect on the accomplishment in the failure group of the performance. So teachers should try to develop efficient teaching method to encourage students to intensify their motive of their accomplishment.

This study aims to provide both basic material regarding the technical psychological discipline of performance enhancement and aid understanding of the characteristics of each step through recognizing, comparing and analyzing psychological hindrance and the treatment methods between professional, possessing high-levels of performance, and semi-professional golfers. A survey was used as the measuring tool. This survey was completed by 30 members of the KPGA (Korea Professional Golfers' Association) who are regular participants in the golf tour and a corresponding number of semi-professional golfers who take part in the second division tour. SPSS 12.0K for Windows was used for data processing. Both cross tabulation(x^(2)) and T-test were used to analyze the statistical data. The results obtained are detailed as follows. Firstly, one major cause of psychological hindrance is problems relating to the swing, balance or rhythm. More professional golfers (96.0%) considered these as psychological hindrance than did semi-pro golfers (80.0%). On the other hand, the results indicate that semi-pro golfers feel greater burden than pro golfers when there are slumping, there are schedule or time changes, bad weather, expected 3 putts, disagreements with caddies and also when the second shot is obstructed. Secondly, when performance is affected due to a lack of discipline, the results indicate a significant difference between the two groups(Other problems do not.), with the influence felt more by the semi-pros than the pros. Thirdly, another significant difference appeared when the players' played badly and their partners' performance was relatively better regarding the treatment methods to mitigate psychological hindrance between the two groups.
