Field training system is an establishment for improving practical ability of college students. That system is a learning experience that are relative to university's regular educational curriculum and industry field training. In order to practice an effective field training system, lots of helps from company, college, students and government's interest are needed. But, in most industry fields, it is hard to accept field training manpower in condition of that has no extra guaranteed budget or staff for field training. Because of it, the biggest matter of college the industry field training is to maintain industry fields. Although students want to be paid properly in industry fields where are furnished the advance facilities and equipments and participated in practices, it is extremely hard situation to achieve it in reality. In this way, the management of industry field training has realistic difficult problems, but it is a necessary system. Therefore, in this paper, methodology and model for industry field training management process are suggested in order to administer effective industry field training. If the industry field training are managed by those system mentioned above, students will have chance to exert their creativeness and speediness through field experience, and industry fields where students can get various dimensions of education are expected to manage.

There are many problems to single sports talents out of test applicants. The physical activity promotion system has been performed to all elements school students of both 5 and 6 grades in order to evaluate overall health and physical activities since 2009. This system includes some variables which could measure the students' sports latent power, so that the system could be used to single out sports talents. In this work, we propose a primary screening method that element school teachers might evaluate sports talents based on the data of the physical activity promotion system. Two more sports talent indices which are sports flexibility index and sports endurance index are defined. The selection method of sports talents is developed by using sports latent indices including sports power and cardiorespiratory indices. This method is efficient from the view of time and cost aspects, since we do not need to remeasure all elements school students again.

This study conducted the following experiment to examine change of biophysical and physical fitness function on combined exercise program in 20' female university students with obesity according to heights of insole. Obesity related biophysical function was measured by basal metabolism and percent body fat(% Fat) and health related physical fitness was measured by isokinetic strength of quadriceps femoris muscle, muscular endurance, flexibility and power on comparative analysis of pre, post exercise and each groups(0cm, 5cm, 9cm) in 36 female university students with obesity subject according to heights of insole. These result lead us to the conclusion that each group were statistically improved at isokinetic muscular strength of quadriceps femoris muscle and basal metabolism, but 5cm group compared with 0cm and 9cm group was more significant improvement. Consequently, combination exercise applying appropriate heights of insole would be lead to positive increment of muscular strength and basal metabolism.

The purpose of this study was to investigate the effects of six weeks of plyometric training on Sargent jumps, posture control, and lower extremity injury criterion in Taekwondo demonstrator. Twenty healthy collegiate Taekwoondo demontrators were randomly assigned to either an exercise group (Ex = 10), and a control group (Con = 10), Con maintained their normal Taekwoondo demontration training schedule. Whereas Ex group completed the plyometric program in three times a week, 60 minute for 6 weeks. Testing before and after training include the Sargent jump, back muscle strength, Y-balance and lower extremity injury criterion. There are no significant increase in back muscle strength, but significant increase in Sargent jump. In postural control, the anterior was not significant, but there was a significant increase in the left and right posterolateral, posteromedial and the total score showed that there was no risk of injuries. In conclusion, plyometric training is a training method that needs to be actively utilized for power, dynamic posture control, lower extremity injury prevention, and rehabilitation.

The aim of this study was to investigate the issue in obese children with a high probability of leading to precocious puberty for they have more advanced skeletal maturation compared to normal children in order to contribute to the health of obese children by identifying the relationship between physique and physical fitness according to their skeletal maturation. A total of 243 obese children between the ages of 10-13 were enrolled as subjects, and the skeletal maturation, which symbolize indicators of biological maturation, were evaluated by using the TW3 method after hand-wrist radiographs, thus classified the skeletal maturation level into retarded group(n=70), normal group(n=128), and advanced group(n=45). A stadiometer and InBody 270 (Biospace, Korea) were used to measure 3 components in physique. A total of 7 components in physical fitness, which included muscular strength, muscular endurance, flexibility, power, cardiovascular endurance, balance, agility, were measured as well. Descriptive statistics and one-way variable analysis (ANOVA) were conducted for data processing using SPSS 25.0, and Duncan's multiple-range method was used for post hoc analysis; and it was considered significant at the level of P< .05. Analysis results of this study may be summarized as follow. First, height and weight in physique factors according to the skeletal maturation between the retarded, normal, and advanced groups in males and females were highly significant. Second, physical fitness comparison according to the skeletal maturation in males were statistically significant in muscular strength, power, and agility whereas muscular strength and balance were statistically significant in females.

This study is to evaluate the availability of cardiorespiratory fitness measurement by 20 m shuttle run test based upon energy contribution rates of elite athletes in different sports type. Sixty-seven elite athletes attending K national university participated in this study. They were divided by three groups based upon sports type, composed of Anaerobic Group (sprint, jumps, weightlifting, throw; n=35), Aerobic Group (medium-long distance; n=9), and Combat Sport Group (judo; n=23). 20 m shuttle run test was conducted by Leger et al.(1982) method and calculating acceleration using measured shuttle run repetitions was conducted by Brewer et al.(1988) method. To test the usefulness of VO₂max, graded exercise treadmill test was conducted and standing long jump and 50 m run were measured as power fitness factors. Z-jump was used for measuring power, agility, and muscular endurance. Standing long jump and 50 m run of Anaerobic Group (AnG) was significantly higher than that of Aerobic Group (AeG) and Combat Sport Group (CG) (p<0.05). However, Z-jump of CG was significantly higher than that of AnG and AeG(p<.05). There was a higher correlation of 20 m shuttle run test and VO₂max in AnG(r= 0.577, p<.0001) and CG(r= 0.760, p<.0001). Otherwise, there was a low correlation of 20 m shuttle run test and VO₂max in AeG. There was no significant group difference to test the availability of 20 m shuttle run test and there was a reduced error when converting 20 m shuttle run results into VO₂max. This study examined the usefulness of 20 m shuttle run test by converting 20 m shuttle run repetition results into VO₂max calculation, which showed reduced error. Therefore, this study confirmed that it would be needed to convert 20 m shuttle run results into VO₂max for universal and practical use in the field without dividing sports type.

This research aimed to enhance the effects of training through the use of infrared cameras located at anterior and posterior positions. The results were as follows. In the case of the smash, the impact time needed to be adjusted to raise their impact point. The smash of S1, on the other hand, was a step smash, which showed the fastest racquet head speed and the greatest transmission of power upon impact. As the max racquet speed upon impact and during speed was similar, S1 showed the best impact time. All athletes except S6 were shown to use their right foot as their 1 step that was located in front upon landing, using a hop step as their first step. For the best swing upon stroke, it is important to make the best conditions possible for the use of elbow joints and wrist joints. The rotating radius of the racquet should be big and the shuttlecock should be fast. Balance is important in footwork, or the coordinated movement of the feet. Without a correct step it is difficult to execute an efficient stroke. In an actual game, steps need to be executed in 2 to 4 steps, and programs focusing on steps according to situation, agility and reaction need to be executed.
