The purpose of this study was to investigate the effect of balance training with upper extremity exercise on the improvement of balance performance in people who have had a stroke. Eighteen candidates who have all experienced a stroke, were living in Dong-Gu, Ulsan and were participating in a community based rehabilitation program, have been included in this study. The program was conducted three times weekly, 1 hour per session, for 7 consecutive weeks. Subjects were tested with 7 m and 100 m Timed Gait Test (sec), Timed Get Up and Go Test (sec), Functional Reach Test (cm) and 5 items of Berg's Balance Test at pre-training and post-training. Total balance index and balance ratios were measured by K.A.T. 3000. The balance training program performed by sitting on a chair and gymnastic ball and standing on stable and unstable surfaces during upper extremity exercises such as Proprioceptive Neuromuscular Facilitation (PNF) upper extremity pattern, picking a ball up from floor, throwing and catching it. After seven weekends of balance training, subjects showed a significant difference in balance test results. The exceptions were three items of Berg's Balance Test (p<.05). Balance index score and affected and unaffected side balance ratio had a larger improvement than pre-training (p<.05). The result of this study showed that intervention of this balance training program could improve the balance performance in people who have had a stroke.

The purpose of the study was to perform trend analysis of the exercise content i.e. element difficulty distribution scores, element group distribution scores obtained by the athletes during 2014 Korea Cup International Gymnastic finals. The conclusion drawn from the analysis are as follows: Firstly in terms of tournament technical difficulty value, Korean athletes showed characteristics of reliance on swing element rather than strength hold element which could actually secure higher difficulty scores. Secondly, skill acquisition of higher difficulty value is demanded by taking advantage of familiar characteristics from the swing element i.e. Jonasson and Roll bwd. Slowly with str. arms and body to swallow (2s.). Thirdly, development of sensory training and strengthening exercise program are essential to enhance strength hold technique.

This study was conducted to investigate the technical factors of Cuervo forward straight vaults with single twist, single and half twists, and double twists actually performed by three execellent male gymnasts participated in artistic gymnastics competition of 2003 summer Universiade in Daegu and the 85th National Sports Festival in Cheongju. To accomplish the research goals the Cuervo vaults of three gymnasts were filmed by using three digital camcorders set by 60 Hz, and data were collected through the DLT method of three dimensional cinematography. The kinematic and kinetic variables as each phasic time, CM displacement velocity, release angle inclination angle hip joint angle landing angle, average horse reaction force average moment arm average torque, whoe body's total remote local angular momentum were analyzed, so the following conclusions were reached. Generally to perform the better Cuervo vault, a gymnast should touch down on the board with the great horizontal velocity of the whole body through the fast run-up, and touch down on the horse by decreasing the horizontal displacement of the whole body during the preflight, so raise CM height gradually within a short horse contact time. He should increase the horse reaction force through checking the horizontal velocity of the whole body effectively and the inclination angular displacement of the handstand, if so he can have the large vertical velocity of the whole body. By using the acquired the velocity and the angular momentum of the whole body, he can vault himself higher and twist sufficiently, then he can get better if the body could be tilted by swinging both arms and perform the cat twist with a little flexions at hip joints. According to the above outcomes we can judge that the best athletes is LuBin, the better is YTY, and the next is JSM.

This study is intended to identify the difference in social skills among adolescent students, by grade gender, rights practice, and self-awareness. It will raise awareness of the importance of the rights of adolescents and provide basic data of guaranteed rights for adolescents and social skills. Using questionnaires, a 569 adolescents, in four middle and high schools in Seoul and the Capital Area, were analyzed. The study results were as follows: first, females showed higher empathy skills than males did in social skills. In the case of male adolescents, self-control skills among social skills, was higher than those of females. Second, practice for rights and self-concept had positive influences on social skills. The higher the practice for rights, the higher cooperation, assertiveness, empathy, and self-control the adolescents had. The more positive self-concept of physical appearance, gymnastic ability, friends, and honesty, trust and value, indicated a higher assertiveness. The result implied that the adolescents' practice for their rights, self-concept, and social skills were highly correlated with one another, and adequate practice for their rights and positive self-concept had influences on their social skills. Based on the results, in order for adolescents with a low level of social skills to have a satisfactory social life, they should be encouraged to practice their own rights in the right direction and to acquire positive self-concept in the future.

This paper presents implementation of localization system using UWB (Ultra-Wide Band) sensors and its experimental results along with development of context-aware services. In order for precise measurement of position, we experimented various conditions of pitch angles, yaw angles, number of sensors, height of tags along with measuring errors at each installation. As an application examples of the location tracking system, we developed an intelligent health training management system based on context-aware technology. The system provides appropriate training schedule to a trainee by recognizing position of the trainee and current status of gymnastic equipments and note the usage of the equipment through a personal digital assistant (PDA). Error compensation on position data and moving direction of the trainee was necessary for context-aware service. Hence, we proposed an error compensation algorithm using velocity of the trainee. Experimental results showed that proposed algorithm had made error data reduce by 30% comparing with the data without applying the algorithm.

In the late 19th century and early 20th century, Among those of the Northeast Asia three countries, school physical education and military-style gymnastics of Chosun can be regarded as having been the most nationalistic. The adoption of modern physical education in public schools was from the proclamation of 'the Order on Building the Country through Education by King Gojong in February 1895. This paper intends to examine the process of adopting military-style gymnastics education which played the central role in school physical education in the late Chosun period. But, unlike the common guess that military-style gymnastics in public schools in late Chosun would have been full of patriotism and nationalism, the textbooks and teaching contents of Chosun Military Officers' School were very similar to those of Japan, which is an unexpected fact. Therefore, Chosun decided to accept the Japanese-type military-style gymnastics and military training to improve physical strength of youngsters and military power. The fact that, with the advent of modern education, physical education was emphasized above all else has a very important meaning to the history of Korean physical education. Physical activity education emerged as a major education course which had been unthinkable in previous ages. The second characteristics is that the process of adopting military-style gymnastics and its contents were influenced by Japan Third, even if military-style gymnastics was imported from Japan as part of school physical education course in late Chosun period, its aim was to train military man powers for the independence movement against Japan, rather than to develop harmonious body.
