The purpose of this study was to investigate the relationship between distance and factors of javelin in korean male's javelin throwing. To accomplish this purpose, the analyzed trail selected total 29 trails (subjects 9) recorded more than 65 m in the 93rd National Sports Festival. The Kwon3D 3.1 version was used to obtain the three dimensional coordinates about the top, grip, end of javelin. And the kinematic data such as projection factors and direction angle of javelin calculated using Matlab2009a program. The statical analysis on the records (n=29) were used to Pearson's product moment correlation coefficient. There was a statistically positive relationship between the records and horizontal velocity (r=.866, ${\rho}$<.01), height (r=.541, ${\rho}$ <.001), height rate (r=.373, ${\rho}$ <.05) and horizontal displacement of javelin (r=.749, ${\rho}$ <.01), but the medial/lateral velocity showed a negative relationship to r=-.663 (${\rho}$ <.01). The attack and yaw angle showed not a significant relationship between the records, but the medial-lateral tilt (E1:r =-.557 [p<.01)] E2:r=-.629 [${\rho}$<.01], E3:r=-.528 [${\rho}$ <.01]) and attitude angle (E2:r=-.629 [[${\rho}$<.01], E3:r=-.619 [${\rho}$ <.01]) of javelin showed a negative relationship between the records, as well as the projection angle of javelin (r=-.419, ${\rho}$ <.05) showed a negative relationship between the records.

This article proposes an ultrahigh frequency band radio frequency identification (RFID) tag antenna for drug runout management that can be used in hospitals. The RFID tag antenna is designed to function as a sensor that alerts drug runout when a drug inside a drip chamber is completely consumed but does not work when a drug remains inside a drop chamber. A previously proposed 915 MHz dipole antenna, is too large to be attached to the drip chamber of a feeding bag. Moreover, the length of the dipole (L) should be increased for conjugate matching with an RFID chip. Therefore, the dipole antenna is downsized so that it can be attached to the drip chamber through a fine meander line structure coupling with a corrugate meander line. A transparent cover is added to enhance the grip force between the designed antenna and the drip chamber and to enable detachment. The dimensions of the completed antenna structure attachable to a drip chamber are 32.59 mm (height) and 13.5 mm (width). The gain reduction due to the decreased antenna length is enhanced. The fabricated antenna shows an average omni-directional read range of 10.65 m on a horizontal plane and has the function of sensing the presence of a drug.

Purpose : The purpose of this study was to determine the changes that occur due to the real-time monitoring of paddle pressures which has an important influence on the defibrillation success rate in defibrillation treatment known as the only treatment for cardiac arrest patients with VF. Methods : 40 people participated in the cardiac arrest simulation training and played the role of the defibrillation operator. Investigators measured the pressure of paddle while defibrillating by using instrument which was developed by the investigator. Results : Through real-time monitoring of the paddle pressures of defibrillator by indicator, the front sternum paddle showed a 77.5% success rate and the apex paddle showed a 40% success rate. While the values without monitoring the paddle pressures, the front sternum paddle showed a 51% success rate and the apex paddle showed a 20% success rate. These experiment revealed statistically significant(p <.001) low success rate. Conclusion : The method of monitoring the paddle pressures during defibrillation showed that the paddle can be precisely gripped. The success rate of paddle pressures is significantly correlated with height, weight and grip strength.

This study analyzed the effect of regular Taekwondo training for 16 weeks on physical fitness and growth index depending on different IGF-1 gene polymorphisms. The subjects of the study were 44 male students who were 8 year years old. The IGF-1 gene showed the highest frequency of 18 CA repeat (190 bp) in 50% of subjects, and was found in the homozygote (n=11), heterozygote (n=22) and non-carriers (n=11). The results of the physical fitness and growth index among the gene polymorphism groups indicated no significant differences but the expected height of the non-carrier group was significantly high (p<0.05). After Taekwondo training, the homozygote group and the non-carrier groups demonstrated significant (p<0.05) increase in grip strength and in time in the standing with one leg while closing eyes test, respectively. Only the homozygote group had a significant (p<0.05) increase in thigh circumference. IGF-1 concentration significantly (p<0.05) increased in the heterozygote group, while HOMA-IR significantly (p<0.05) decreased in the homozygote group. Furthermore, there was a significant (p<0.05) decrease in glucose in both the homozygote and the non-carriers groups. The difference between physical fitness and growth index depending on the IGF-1 gene polymorphism after Taekwondo training did not show consistent impact.

Purpose : This study used a sarcopenia diagnostic algorithm proposed by the Asia working group in adults over 50 to diagnose sarcopenia and analyze body function. The purpose of this study is to prepare basic data for the management and prevention of sarcopenia. Methods : We performed a diagnostic evaluation of sarcopenia in 97 adults over the age of 50 years with the cooperation of the Seongnam senior experience complex in Seongnam-si, Gyeonggi-do. As a result of the diagnostic process, 24 subjects were placed into the sarcopenia group, while 73 subjects were placed into the normal group. We measured each subject's body, performed the timed up and go test to evaluate functional mobility, and conducted a questionnaire on the pre-symptom of locomotive syndrome and locomotive syndrome. Results : There were statistically significant differences in height, weight, and skeletal muscle mass between the two groups. There was also a statistically significant difference in the timed up and go test, which confirmed the difference in functional mobility between the two groups. In addition, there was a statistically significant difference between the two groups in the proportion and the mean score of subjects with pre-symptom of locomotive syndrome and locomotive syndrome. In the correlation analysis, grip strength was statistically significantly correlated with height, weight, skeletal muscle mass, waist circumference, timed up and go test, pre-symptom of locomotive syndrome and locomotive syndrome. Gait speed was significantly correlated with the timed up and go test and locomotive syndrome. Appendicular skeletal muscle index was significantly correlated with height, weight, waist circumference, hip circumference, and the pre-symptom of locomotive syndrome. Conclusion : In conclusion, sarcopenia is closely related to height, weight, skeletal muscle mass and functional mobility, as well as the pre-symptom of locomotive syndrome and, locomotive syndrome. In consideration of this, the prevention and management of sarcopenia should be made accordingly.

Purpose : We aimed to investigate the effects of nutritional foods on sarcopenia prevention and physical function among the elderly living in rural communities during the COVID-19 pandemic by providing customized nutrition. Methods : This study was conducted in the rural community of SCC. Participants (n=24, over age 65) were randomly assigned into a Protein group (n=12) and a Vitamin group (n=12). The protein group was given 23 g/d of protein (whey, soybean, BCAA) for 8 weeks and the Vitamin group 23 g/d of vitamin (B, C, D, E and mixed minerals such as calcium, magnesium, zinc) for 8 weeks. All participants had their body composition such as height, weight, skeletal muscle mass, body mass index, and body fat percentage, measured using bioelectrical impedance analysis (BIA) and physical function assessed using grip strength and the short physical performance battery (SPPB). Results : At the end of the intervention, there was a significant increase in skeletal muscle mass (p<.01) in the Protein group (p=.002, 4.92 %) compared to the baseline: it increased by 2.33 %. The Vitamin group had a significant increase in body fat percentage after the intervention (p=.001, 15.35 %) compared to the baseline: body fat percentage decreased by 4.49 %. There were no significant differences in left and right Grip strength/Weight, SPPB, 4-m gait speed, chair stand test, and sense of balance in both groups. Conclusion : The findings from this study suggest that 8 weeks of protein intake have a significant effect on skeletal muscle mass and body fat percentage. Protein intake helped promoting the health of the elderly in rural community during the COVID-19 pandemic. It will assist creating a foundation for providing customized nutrition for the elderly in rural community in the future.

The purpose of this study was to examine changes in nutrient intake in patients at nutritional risk. We included 106 malnourished patients who were admitted to Severance Hospital from March to September 2014. The average age was $59.0{\pm}11.6$ years old and 59 patients were male (59.7%). The majority of diagnosis was cancer (94.3%). We evaluated patients' nutritional status by scored patient-generated subjective global assessment (PG-SGA), anthropometric measurement (height, weight, body composition by Bioelectrical impedance analysis), hand grip strength, biochemical and dietary assessment. The patients' daily intakes of energy and protein ($1,019.5{\pm}706.4kcal$, $40.4{\pm}27.7g$) during hospitalization were significantly lower than their usual intakes ($1,382.0{\pm}499.8kcal$, $54.4{\pm}25.1g$, P<0.001). Serum levels of albumin, cholesterol, and total lymphocytes were significantly reduced during hospital stay. The negatively influencing factors for reduced dietary intake were anorexia (42.5%), abdominal distention (14.2%), pain (13.2%), and others. The results of this study could be used to establish baseline data for developing new strategies for nutritional intervention in malnourished patients.
