The purpose of this paper is showing the data in order to insure substantiality of infant physical education, normalize it, and help effective physical activities, by research on the actual condition of infant physical activities. For this purpose, I surveyed the research on the actual condition of infant physical activities and analyzed it, after selecting 847 parents randomly including 412 male parents and 435 female parents whose children go to kindergarten in City C. My survey analysis shows the following conclusion : 1. Infants socialization develops after the physical activities more than before the physical activities. Their emotional status and physical condition also develop. Their personalities change after the physical activities into extroversive characters from the introversive. 2. Most children do physical activities by the need of themselves or their parents. The motive of physical activities is for better socialization and health. The first priority of physical activities the quality and atmosphere of leaders. 3. Many parents say that they will recommend infant physical activities to other parents and 95.6% of them say that they will let their children continue the physical activities. They want their children`s physical activities to be focused on physical growth, confidence development and the rules of etiquette. What most parents are satisfied with after the physical activities are their development of sports technique, self-confidence and health itself. 4. Most parents let their children enjoy the physical activities but do not let them have a job as a sportsmen. The reason why children give up the physical activities is usually that they are afraid of their leaders or unfamiliar atmosphere. 50% of the parents let their children quit the physical activities when their children want to give them up, while 50% of them have their children continue them persuading their children. It shows that the leaders` concern about the children is important. Parents think corporal punishments help physical activities : especially chastisement and hitting them on the hips slightly. quality of leaders, improved equipments and effective public relations are needed. It is expected that the government and public offices as well as universities should study on more active infant physical activities. 5. Most children want swimming and TaeKwonDo. They want physical activities for 30 minutes to an hour, and prefer in groups in the afternoon two to four times a week. The fees of physical activities are high for them, under 50,000 Won per month is preferrable. Many parents consult their children`s physical activities with the leaders while less parents do not. The reason why they do not consult is that their children are doing well or they do not have enough time to consult. 6. To make infants physical activities vigorous, various programs should be developed, and higher

These are the results of investigative analysis focusing on the actural condition of 801 spats playas who participate in weight relevant sports. This research pried classifies the players by sex (564 males, 237 females) and by region (250 from large metropolitan areas, and 561 from small towns) 1) Most of these athletes joined their particular sport an their own, while others joined because of their coach`s suggestion to do so. Satisfaction with their own participation in their respective spats is around 40%. They do not, however encourage others to participate in similar weight relevant sports -- the reason bang that a high percentage say that it is difficult to lose weight and maintain that weight loss. Exactly 50.94% say that they want to continue in their sport, but when faced with the challenge of $quot;making weight$quot; they world change to arms kind of spat if possible. 2) The results show that most of the athletes lose weight just prior to a game or match. The motive behind such drastic weight loss has to do with the platter`s strategy for facing an opponent of a weaker weight class, ar may be related to the team`s line-up against a particular opposing team. However, there ate other athletes who don`t feel that it is necessary to lose weight because they are already at their optimal level. 3) The statistics show that the athletes lack the proper training skills and methodology of weight Ices training. Generally, most hear of weight loss training through word-of-mouth information from veteran teammates. Weight loss training by word-of mouth information is more commonly known than the advice gives by coaches. Coaches are usually able to pass a their expertise regarding weight loss to the players at a rate of 56.43%. 4) The player respond that the prevalent watt loss method is through a restricted diet and increased exercise. Popular opinion holds that that method best -- and the worst method being medicinal therapy. The rata that the coaches one able to persuade players to actually apply a diet/exercise regimen is at 46.94%. 5) The diet plan is used because it is relatively easy to reduce weight, and also to maintain that weight loss. The reason cited fog using mecicinal they is that it facilitates rapid weight loss, even when alternative ids have reached than limits. 6) Regarding the question of whether a not the coaches know if their players are using medicinal therapy or not, 58.30% report that they do not know. When a coach discovers that a playa has used any kind of drugs to induce weight loss, severe punishment follows. These days, very few players choose medicinal therapy, and generally drug tests ate not administered on the day of the sporting event. However, a very high parentage of the players is in favor of imposing a mandatory drug test. 7) After extreme wight loss, feelings of insecurity set in, as well as a loss in self-confidence. Physiologically, constant thirst and hunger were cited as a problem. Diminished strength and swollen glands were noted as a side effect. Additionally, hands and other parts of the body are more likely to fall asleep. 8) The majority of athletes recover from their drastic weight loss through relaxation techniques, and by replenishing their bodies with proper nutrition. Their coaches` advice for faster recovery is basically the same method. 9) Proper weight loss methods will be implemented as more people become aware of those methods and develop a moral consciousness. Moreover, the problem of excessive weight loss should be a as a national concern for its athletes. Current methods should be continually modified and improved upon to ensure the safety and well-being of ow sport enthusiasts.

Since a LED light source does not include the mercury(Hg) or a filament, it is expected as an environmentally friendly next generation Light source with its good reliability and long lifetime. A few ten mW white LED can substitute for the indicator light source, and it is required to study several watt multi-chip semiconductor light sources in order to replace the light sources for general illumination such as incandescent lights and fluorescent lamps. The light sources for illumination have a variety of applications in the indoor and outdoor, and the variation of optical power and color rendition of the light source limits their applications. Therefore, it is necessary to research the LED lamp and its luminaire to minimize the variation of dynamic characteristics due to that illuminating environment.
