The purpose of this study was to analyze attack skills and scores in 8 weight classes of female Taekwondo athletes who participated in the semi-final and final matches(48 athletes) in the 14th Asian Games(2002, Busan). The 14th Asian Games was chosen for this study because it is in these games that the rules were revised to a variable scoring system. The results obtained from this analysis were as follows; 1. Korean female athletes: No significant difference was found in attack frequency in the light weight class and the heavy weight class. The attack frequency in the light weight class was shown to be in the following order: momtong-dolryeochagi(217 times), naraechagi(48 times) and dichagi(15 times). The attack frequency in the heavy weight classwas shown to be in the following order: momtong-dolryeochagi(263 times) and tchikeachagi(15 times). 2. Foreign female athletes: No significant difference was found in attack frequency in the light weight class and the heavy weight class. The attack frequency in the light weight class was shown to be in the following order: momtong-dolryeochagi(555 times), naraechagi(32 times) and dichagi(12 times). The attack frequency in the heavy weight class was shown to be in the following order: momtong-dolryeochagi(555 times), tchikeachagi{35 times) and naraechagi(35 times). 3. There is a significant difference in attack frequency in the light weight group of Korean female athletes and foreign female athletes, Between groups, in case of quick body attack, such as momtong-dolryeochagi and naraechagi, the frequency of korean athletes was shown to be higher and scores obtained were higher. In case of high score face attack, such as eolgul-dolryeochagi and tchikki, the frequency of foreign atheletes was shown to be higher 4. There is a significant difference in attack frequency in the heavy weight group of Korean female athletes and foreign female athletes, Between groups, in case of quick body attack, such as momtong-dolryeochagi and naraechagi, the frequency of Korean athletes was shown to be higher and the foreign female athletes' eolgul-dolryeochagi and dwitchagi score rates were shown to be the higher.

The purpose of this study was to analyze attack skills and scores in 8 weight classes of male Taekwondo athletes who participated in the semi-final and final matches(48 athletes) in the 14the Asian Games(2002, Busan). The 14th Asian Games was chosen for this study because it is in these games that the rules were revised to a variable scoring system. The results obtained from this analysis were as follows; 1. There is a sinificant difference of attack skill frequency per Korean(Foreign) male athlete was 50.00(51.38) times and scores obtained were an average of 5.06(4.25) points per athlete. 2. There is a significant difference in attack frequency between the light weight group and heavy weight group of Korean and Foreign male athletes. Korean male athletes: Between groups, in case of momtong-dolryeochagi, naraechagi and tchikeachagi, the frequency of the light weight group was shown to be higher. The frequency of momtong-dolryeochagi was shown to be higher in the heavy weight group. 3. There is a significant difference in attack frequency between Korean male athletes and Foreign male athletes in the light weight group and heavy weight group. The light weight group: Between groups, in case of momtong-dolryeochagi and eolgul-dolryeochagi, the frequency of Korean male athletes was shown to be higher and in case of naraechagi, dwitchagi and dolgaechagi, the frequency of Foreign male athletes was shown to be higher. The heavy weight group: Between groups, in case of and eolgul-dolryeochagi, naraechagi and dwitchagi, the frequency of Korean male athletes was shown to be higher and in case of momtong-dolryeochagi, tchikeachagi and dolgaechagi, the frequency of Foreign male athletes was shown to be higher.

The purpose of this study was to determine the effect of the Taekwondo program on cognitive competence of children with mental retardation. The subjects were 18 children with mental retardation. The children were devided into two groups. One group(n=9) was in an experimental group and the other group(n=9)was a control group. To find out any changes of their cognitive competence, the Taekwondo program was executed to the exercise group three times a week, for forty minutes a day over ten weeks......

This research fulfilled the program of aerobic exercise for living during 6 months with seven men and women who are disabled people with visual impairment, The program consists or gym, swimming, aerobic and running, During 6 months, all exercises were executed 1 hours, twice a week for 6 weeks. Each exercise had self-servant and was carried out 60 minutes with teaching method of special directors in every weep Physique by height, weight, condition of exercise ability by the capacity of the lungs of the heart and lung endurance and intake of the maximum oxygen, muscular strength of stomach, grasping power, pliability by forward bending with the upper part of the body, instantaneous force of muscle in a sudden jump, muscular endurance by put-up and sit-up, agility by side-step and response of the whole body, and balance by one leg standing while closing eyes as using Helmas (sewoo systems korea) were measured. The Results, 1.There is a significant difference for both men and women in the capacity of the lungs and the heart and lung endurance, However only women have a significant difference in intake of the maximum oxygen. 2. Both men and women have a significant difference in muscular strength of stomach and grasping power to measure muscular strength. 3. Both men and women have a significant difference in forward bending with the upper part or the body to measure flexibility. 4. Sudden jump to measure instantaneous force of muscle, sit-up, and push-up to measure muscular endurance show that both men and women have a significant difference.(p<.01) 5. Side-step and response of the whole body to measure agility show that both men and women have a significant difference. 6. One leg standing with closing eyes to measure balance show that both men and women have a significant difference.
Proteomic analysis of Caenorhabditis elegans.

<P>Proteomic studies of the free-living nematode Caenorhabditis elegans have recently received great attention because this animal model is a useful platform for the in vivo study of various biological problems relevant to human disease. In general, proteomic analysis is carried out in order to address a specific question with respect to differential changes in proteome expression under certain perturbed conditions. In this chapter, we focus on gel-based proteomic analysis of C. elegans subjected to two specific stress conditions during development: induction of the dauer state for whole body protein expression and a temperature shift for egg protein expression. Utilizing these differently perturbed C. elegans protein samples, two-dimensional electrophoresis and differential in-gel electrophoresis methods have led to the discovery of remarkable aspects of the worm's biology. We also provide numerous details about the technical points and protocols necessary for successful experimentation.</P>
Chemical structure and biological activity of the Caenorhabditis elegans dauer-inducing pheromone
Jeong, Pan-Young,Jung, Mankil,Yim, Yong-Hyeon,Kim, Heekyeong,Park, Moonsoo,Hong, Eunmi,Lee, Weontae,Kim, Young Hwan,Kim, Kun,Paik, Young-Ki Macmillan Journals ltd., etc.] 2005 Nature Vol.433 No.7025
Pheromones are cell type-specific signals used for communication between individuals of the same species. When faced with overcrowding or starvation, Caenorhabditis elegans secrete the pheromone daumone, which facilitates communication between individuals for adaptation to adverse environmental stimuli. Daumone signals C. elegans to enter the dauer stage, an enduring and non-ageing stage of the nematode life cycle with distinctive adaptive features and extended life. Because daumone is a key regulator of chemosensory processes in development and ageing, the chemical identification of daumone is important for elucidating features of the daumone-mediated signalling pathway. Here we report the isolation of natural daumone from C. elegans by large-scale purification, as well as the total chemical synthesis of daumone. We present the stereospecific chemical structure of purified daumone, a fatty acid derivative. We demonstrate that both natural and chemically synthesized daumones equally induce dauer larva formation in C. elegans (N2 strain) and certain dauer mutants, and also result in competition between food and daumone. These results should help to elucidate the daumone-mediated signalling pathway, which might in turn influence ageing and obesity research and the development of antinematodal drugs.
