The purpose of this study is to examine the success or failure on the balance beam in element group requirements posture which is bending salto side-ward tucked through kinetic analysis. The national team players were participated. The goal was to present training methods to coaches and athletes so as to provide scientifically useful information. The results from this study were summarized as below. When the performance was successful, the features of the body's center of gravity during the side somersault motion showed to spread from the center of the balance beam and the center of the gravity moved to the direction of the body's rotation. In the spring sections - event2 and 3, when the performance was successful, up/down fluctuation became more wider and increased air time. It supported the result that the projecting variable was higher than in failure trial. In addition, the right side hip joint angles and speed, and angular velocity as jumping up for a leap were larger than in failure trial. Those variables showed the optimal conditions for a leap. By increasing the speed of the upper limb from the shoulder and the speed of the shoulder joint angular velocity, the momentum was increased. Especially the right side shoulder joint angular velocity increased dramatically because the right leg was held. As to the side somersault motion, the angular momentum of successful trial with respect to x-axis was bigger than failed trial. It indicated that the increasing angular momentum with respect to x-axis was an important factor in flying motion. Besides, as to side somersault, the appropriate proportion of angular momentum with respect to y-axis and z-axis was a key to successful trails.

Since ICT convergence became a major issue, German government has carried forward a policy 'Industry 4.0' that triggered ICT convergence with manufacturing. Now this trend gets into our stride. From this facts, we can expect great leap up to quality perfection in low cost. Recently Korean government also enforces policy with 'Manufacturing 3.0' for upgrading Korean manufacturing industry with being accelerated by many related technologies. We, in the paper, developed a custom-made operational big data analysis platform for the implementation of operational intelligence to improve industry capability. Our platform is designed based on spring framework and web. In addition, HDFS and spark architectures helps our system analyze massive data on the field with streamed data processed by process mining algorithm. Extracted knowledge from data will support enhancement of manufacturing performance.

Objectives: Suicide rate in South Korea is one of the major public health concerns. This study examined the factors influencing the suicide methods of people who committed suicide in Gyeonggi-do, which accounts for one-fourth of the population of South Korea. Methods: This study analyzed the data of a total of 13,945 suicide deaths in Gyeonggi-do over a five-year period (2016-2020) provided by the Statistics Korea and the influence of social and demographic characteristics on the analyzed suicide methods. The differences in suicide methods according to the social and demographic characteristics of suicide victims were compared and analyzed through chi-squared, and items with significant differences in univariate tests were analyzed by multiple logisitic regression analysis. Results: Among suicide deaths, the most common method of suicide was hanging (52.4%). In particular, women, were employed, and stayed at home were higher risk of being hanged. The second most common method of suicide was leaping (17.7%). Women under the age of 30, those with a college degree or higher, those who were not working, time of death (6-12), and those outside the home were more likely to choose to take the leap. The third most common method of suicide was gas poisoning (15.8%). Young people under the age of 65, college graduates or higher, without a spouse, were employed, and spring season were at increased risk of choosing gas poisoning. Conclusions: The results highlight the need for policies that consider risk factors such as gender, age, education, marital status, employments status, time of suicide, and place of suicide in order to block access to suicide methods for suicide victims in Gyeonggi-do.

When feeling the pulse, healthy man' pulse is the criterion for diagnosis whether you are a sick person. Healthy man is defined as one who is harmonious and not sick in sympathy with natural order. Among the factors for being Healthy man, breathing and pulsation, Chon-gu(寸口) and Inyeong(人迎) are most closely connected with the representative methods of feeling the pulse which are used currently. According to "Hwangjenaegyeong(黃帝內經)" on breathing and pulsation, the pulse beats twice per a breathing-in and a breathing-out each. And for a specific breathing, it beats 5 times including the remnant with a big breath. That the pulse beats twice means that it beats not only twice, but also regularly and repeatedly. The remnant is related to the meaning on a leap month, 5-time beating during a breath is connected with the contents of Osipyeong(五十營). A human is not always in stable and sticks to balance continuously with changes under the circumstances. So when it comes to a criterion how to measure the pulsation frequency, breathing is much more reasonable than pulsation and breathing calculated for a minute. According to "Hwangjenaegyeong(黃帝內經)", Healthy man is the person of whose Chon-gu and Inyeong are in order and much the same in response to each other. Although there is a minor difference in the meaning of term between Chon-gu and Gigu(氣口), Maekgu(脈口) in originally, it is used as almost same meaning when Chon-gu is used in opposition to Inyeong. Afterwards, depending on medical men, around neck or Chon-gu of the left hand are measured for Inyeong. However, Inyeong described in "Naegyeong(內經)" is Jokyangmyeong(足陽明) and it means the Hyeol(穴) around neck where the pulse beats, it looks like about the carotid area. Chon-gu is fall under Eum(陰) and Inyeong(人迎) is fall under Yang(陽). Therefore Chon-gu is continuous with eumgyeong(陰經) and Inyeong is continuous with yanggyeong(陽經). In addition, the pulse and the four seasons meet each other and Inyeong is a little stronger in spring summer and Chongu is a little stronger in fall winter.
