The purpose of this study is to investigate muscle function and symmetry index during whole body vibration exercise using lower extremity training posture for throwing athletes. For throwing athletes in their 20s(6 males, 4 females, age: 24.60±0.92years, height: 177.90±7.40cm, weight: 92.90±22.97kg), lower extremity training postures with squat, carphrase, and lunge movements. Whole body vibration exercise training was performed using. Tensiomyography(TMG) variables Time Delay(Td), Time Contraction(Tc), Time Sustain(Ts) Time Relaxation(Tr), and Displacement Maximumal(Dm) in the lower extremity joint muscles(biceps femoris(BF), gastrocnemius lateral(GL), gastrocnemius medial(GM), rectus femoris(RF), tibialis anterior(TA), lateral vastus(LV), medial latissimus(ML)), were measured to compare and analyze muscle activity, muscle fatigue, and left-right symmetry. The results of the study are left RF, VL, right VM (p<.05) in Td, VM (p<.05) in Tc, GM in Ts (p<.05), left RF in Tr, and right TA (p<. 05) showed a change. Therefore, it has been proven that various whole-body vibration training is an effective exercise with changes in muscle contraction, and stability of the core is secured by symmetry of the left and right muscles. For this reason, the whole body vibration exercise will have a positive effect on rehabilitation training, and it is believed that it will be able to improve performance.

This paper is a study on the digitization of an analog 3D pen. The term digital implies features such as homeostasis, transformability, combinability, reproducibility, and convenience of storage. One device that produces a combination of these digital characteristics is a 3D printer, but its industrial use is limited due to low productivity and limitations with materials and physical characteristics. In particular, improvements are required to use 3D printers, such as better user accessibility owing to expertise and skills in modeling software and printers. Complementing this fact is the 3D pen, which is excellent in portability and ease of use, but has a limitation in that it cannot be digitized. Therefore, in order to secure a digitalization capability and ease of use, and to secure the safety of printing materials that pose controversial hazards during the printing process, research problems and alternatives have been derived by combining food, and digitization was demonstrated with a newly developed 3D pen. In order to digitize the 3D pen, a sensor in a structured device detects the motion of an analog 3D pen, and this motion is converted into 3D data (X-Y-Z coordinate values) through a spatial analysis algorithm. To prove this method, the similarity was confirmed by visualization using MeshLab version 1.3.4. It is expected that this food pen can be used in youth education and senior healthcare programs in the future.

The survey conducted with 120 florists in Korean domestic flower shops to investigate the use and awareness of floral preservatives in Korea. As a result, only 19.8% of the domestic florists use floral preservatives frequently in their shops, whereas 45.5% do not use them at all, suggesting very low use frequency. Korean domestic florists considered the use of floral preservatives mostly for storing cut flowers to preventing bacteria growth. For the reasons not to use floral preservatives, 51.4% of the Korean domestic florists did not value its usefulness, showing a lack of awareness of floral preservatives. However, 44.2% of the florists who had the experience with floral preservatives satisfied with the effect of floral preservatives, and 49.5% of the respondents positively answered to recommend floral preservatives to others. General awareness on floral preservatives among Korean domestic florists was positive. 50.5% of the florists with the experience with the floral preservative had the high intention to re-purchase the flower preservatives. The low use frequency and lack of recognition of floral preservatives in Korea were likely due to very few floral preservative brands and little advertising. However, the high satisfaction level and repurchase intention rate shown by the florists indicates that increasing advertising and education for the floral preservatives would improve the accessibility and awareness of the products and their effects increasing the opportunity to use floral preservatives among Korean domestic florists, further enhancing consumers' satisfaction by improving the cut flower quality and its vase life.

Both in the East and the West, the most classical question in classical political philosophy was 'what is truly a human virtue and a good life?' 'Human virtue' and 'Good life', and 'good State' are thus essentially tied together. Platon And Confucianism. We began with Platon and Confucianism's definitions of human virtue & good life, and 'good State'. This Essay attempts to systematically approach to what Confucianism thinks as a human virtue and a good life in contrast with Platon. Confucius asserted that the most humane human life is a civilized life and it means to realize the value of 'benevolence as a human virtue. 'Mencius also concurred that Confucius's explication of the good life was right. Moreover, he argued that to realize this, political practice should follow. Mencius discussed about 'Four Virtues', the essential goodness of human, confirmed by 'Four Clues (四端)' to talk about the possibility of realizing the good life and a good state. On the other hand, he devised Politics of benevolence.)' as a practical tool for it. An classica eastern philosophy(platon and confucianism) consider a human beings as human relationship. Confucianism believe in reality of the human mind & it's nature. Confucian human mind & it's nature is comprised of benevolence, righteousness, propriety and wisdom. Confucianism proposed that we have to approach to other man as benevolence.

This study is focused on the historical route in which reconciliation between work and family has been operating in the United States whose welfare standards are low, by using analytic narratives, from late 19th century to early 20th century. The first step saw an increase in the social advancement of unmarried women due to the increase in employment in the occupation of white-collar, as well as the increase of women in the Academy and in educational institutions. In the second step, the social advancement of married women was increased by the enforcement of the New Deal, consumption capitalism, and World War II. In the third step, the sphere of highly-educated women was expanded to a professional one through active measures aimed at gender equality, and the women's liberation movement of the 1960s took place. The United States' path model was completed in the fourth step. This study show that the most important factors have a significant influence to complete route of the American's Route were individual efforts of women (capacity building through the academic and the powerful women's movement) and the individual employment relationship in labor market. This study shows that individual efforts of women, especially in building capacity through the academic and the powerful women's movement, and the labor market, whose individual employment relationship is well-developed, have a significant influence on completing the route of the highly educated middle-class women in America.

Because of the global warming, the Arctic Ocean is expected to be ice-free by the year 2035. When the Arctic Ocean will be opened, a number of national interests will become more salient as experiencing a shortened sailing distance and decreasing navigation expense, possibility of natural resources transport by sea from Arctic Circle, and indirect-profit making by building a herb port in Asia. To secure the national interests and support the free activities of people in this region, R.O.K government is trying to make advanced policies. In order to carry out the naval tasks in the Arctic Ocean, using the operational characteristics(mobility, flexibility, sustainability, presence of capabilities, projection) is necessary. To this end, ROK Navy should analyze the operational environment (O.E.) by its capability(weakness and strength), opportunity, and threat. R.O.K. Navy should make an effort over the following issues to implement the tasks in the Arctic Ocean: first, Navy needs to map out her own plan (Roadmap) under the direction of government policies and makes crews participate in the education·training programs in home and abroad for future polar experts. Third, to develop the forces and materials for the tasks in cold, far operations area, Navy should use domestic well-experienced shipbuilding skills and techniques of the fourth industrial revolution. Next, improving the combined operations capabilities and military trust with other countries in the Arctic region to cover the large area with lack of forces' number and to resolve the ports of call issues. Lastly, preparation in advance to execute a variety of missions against military and non-traditional threats such as epidemics, HA/DR, SOLAS, in the future operation area is required.

Honey bees are a vital part of the food chain as the most important pollinators for a broad palette of crops and wild plants. The climate change and colony collapse disorder (CCD) phenomenon make it challenging to develop ICT solutions to predict changes in beehive and alert about potential threats. In this paper, we report the test results of the bee-counting system which stands out against the previous analogues due to its comprehensive components including an improved dual infrared sensor to detect honey bees entering and leaving the hive, environmental sensors that measure ambient and interior, a wireless network with the bluetooth low energy (BLE) to transmit the sensing data in real time to the gateway, and a cloud which accumulate and analyze data. To assess the system accuracy, 3 persons manually counted the outgoing and incoming honey bees using the video record of 360-minute length. The difference between automatic and manual measurements for outgoing and incoming scores were 3.98% and 4.43% respectively. These differences are relatively lower than previous analogues, which inspires a vision that the tested system is a good candidate to use in precise apicultural industry, scientific research and education.

This study is a descriptive correlation study to identify the factors affecting life satisfaction for shift service workers and is a secondary data analysis study using the raw data from the Fifth Korean Work Environment Survey. Five hundred and seventy-seven study subjects were selected from 20-year-old wage workers who had more than one year of work experience at the time of the survey and had worked more than 40 hours a week. The analysis used SPSS 23.0 WIN, including a t-test, one-way ANOVA by Scheffe test, Pearson's correlation oefficients, and Hierarchical multiple regression analysis. Regarding the general characteristics of the subjects, there was a difference in life satisfaction according to age, educational level, industrial type, and subjective health status. The higher the work-life balance and work satisfaction of the shift service worker, the higher the life satisfaction. In addition, social support had a moderating effect on the relationship between work-life balance and work satisfaction of shift service workers. Active social support, work satisfaction, and work-life balance improvement promotion programs were developed and applied to shift work service workers considering the factors influencing life satisfaction, thereby improving the life satisfaction of work shift service workers.
