As fusing IT and medical technique, the number of patients who adhere medical equipment inside of them is increasing. However there is a problem of for the third person to tap or modulate the patient's biometric data viciously. This paper suggests quantum encryption-based key distribution model to share key for the third person not to tap or modulate the patient's biometric data between patient and hospital staff. The proposed model uses one-time pad key that shares key sending random bits not direct sending message of quantum data. Also, it guarantees patient's anonymity because the biometric data of injected-device in the body doesn't be exposed unnecessarily.

Incidence of low-temperature contact burn by use of an electric pad is increased recently, especially in depressed sensory. Acquired immune deficiency syndrome patient using antiretroviral agent suffered with sensory depression as side effect. There are many limitations in wounds treatment of these patients. These patients are vulnerable to infection due to their weak immunity, so it is necessary to keep them in a state of isolation when a wound occurs. We report a case of a third degree burn by electric pad with a surface area of approximately 5% of the body surface of a patient who underwent a sensory depression, which is a side effect of antiretroviral drugs used for treatment in patients with AIDS. In this regard, we report the case with literature review, which is safely recovered using negative-pressure wound therapy and split-thickness skin graft.

The objective of the present study was to determine the best model to describe and quantify the changes in live body weight, height at withers, height at rump, body length and chest girth of Holstein cows raised under Korean feeding conditions for 50 months. The five standard growth models namely polynomial linear regression models, regression of growth variables on the first and second-order of ages in days (model 1) and regression of growth variables on age covariates from first to the third-order (model 2) as well as non-linear models were fitted and evaluated for representing growth pattern of Holstein cows raised in Korean feeding circumstances. Nonlinear models fitted were three exponential growth curve models; Brody, Gompertz, and von Bertalanffy functional models. For this purpose, a total of 22 Holstein cows raised in Korea used in the period from April 2016 to May 2020. Each model fitted to monthly growth curve records of dairy cows by using PROC NLIN procedure in SAS program. On the basis of the results, nonlinear models showed the lower root mean square of error (RMSE) for live body weight, height at withers, height at rump, body length and chest girth (12.22, 1.95, 1.55, 4.04, 2.06) with higher correlation coefficiency (R²) values for live body weight, height at withers, height at rump, body length and chest girth (0.99, 0.99, 0.99, 1.00, 1.00). Overall, the evaluation of the different growth models indicated that the Gompertz model used in the study seemed to be the most appropriate one for standard growth of Holstein cows raised under Korean feeding system.

The purpose of this study was to examine the effect of Yoga and Pilates training on the obesity indexes, muscle mass in each body part and physical fitness of male college students in an effort to provide some clinical information on exercise prescription. The subjects in this study were 20 selected obese male students. A yoga group and a pilates group were organized with 10 students each, and the training was provided for 12 weeks, 5 times a week, 90 minutes each. The findings of the study were as follows: First, both of yoga and pilates made significant differences to obesity indexes(an increase in skeletal muscle mass, a decrease in BMI, a decrease in body fat rate and a decrease in WHR), to muscle mass in each body part(an increase in muscle mass on the right arm, left arm, trunk, right leg, and left leg), and to physical fitness(an increase in lower extremity muscle strength, muscular endurance, flexibility, left balance and right balance). Second, pilates exercised a more signifiant influence than yoga on an increase in skeletal muscle mass, the improvement of muscle mass in each body part(an increase in muscle mass on the right arm, left arm, trunk, right leg and left leg), and the improvement of balance(left and right). Third, yoga had a more significant impact on a decrease in BMI, body fat rate and WHR. Given the findings of the study, yoga and pilates seem to be efficient exercise programs to improve the obesity indexes of obese male college students and promote their health.

This study was conducted to investigate the effects of L-carnitine with different levels of lysine on performance of pigs weaned at 21 days of age. A total of 120 pigs were allotted into a $3{\times}2$ factorial design with three different levels of lysine (1.40%, 1,60% and 1.80%) and two levels of L-carnitine (0 and 1,000 ppm). Each treatment had 4 replications with 5 pigs per replicate. Pigs of $22{\pm}1$ days (5.9 kg of body weight) were grouped into a completely randomized block design. Treatments were 1) 1.4-Crt; 1.40% of lysine with 1,000 ppm of L-carnitine, 2) 1.4-N; 1.40% of lysine without L-carnitine, 3) 1.6-Crt; 1.60% of lysine with 1,000 ppm of L-carnitine, 4) 1.6-N; 1.60% of lysine without L-carnitine, 5) 1.8-Crt; 1.80% of lysine with 1,000 ppm of L-carnitine and 6) 1.8-N; 1.80% of lysine without L-carnitine. Growth performance was optimized in pigs fed 1.6% lysine regardless of carnitine addition. For the first 7 days of the experimental period, the best ADG and F/G were found in pigs within the 1.6-Crt group. Carnitine significantly improved (p<0.05) ADG of pigs when the lysine level in the diet was 1.6%. Only in the third week carnitine had a significant influence on growth performance of pigs. A lysine-sparing effect of L-carnitine was not detected in this study. The 1.6-Crt group showed the best proximate nutrient digestibility, and the crude fat and gross energy digestibility were higher when the L-carnitine was added in the diet. Lysine level significantly affected the digestibilities of DM (p<0.001), GE (p<0.001), CP (p<0.01) and C.fat (p<0.05). Carnitine also significantly improved digestibility of nutrients. Lysine level as well as carnitine level affected the amino acids digestibility, however, in 1.8% lysine diet carnitine did not influence on amino acids digestibility. Plasma carnitine content was significant higher (p<0.05) in pigs fed L-carnitine. This indicates the increased biological availability of carnitine within the body. L-carnitine supplementation tended to improve feed utilization during the third week (p<0.10) and during the entire period (p=0.10). Lysine level significantly affected feed utilization of pigs during the third week and entire period (p<0.05). As pigs grew, the lysine requirement was reduced.

All times of minimum light for two eclipsing binaries V343 Aql and CX Aqr were collected and analyzed to study their orbital period variations. It was found that the orbital periods for both stars have varied in a cyclical way superposed on a parabola. A secular period decrease of $-261{\times}10^{-7}$ d/y for V343 Aql was calculated while CX Aqr showed a secular period increase of $+2.55{\times}10^{-8}$8 d/y. Possible causes of secular period variations for two systems were discussed. The cyclical period variation was interpreted as light-time effect due to a third body. The resultant period, semiamplitude and eccentricity of the light time orbit were calculated to be 30.3y, 0.0092d and 0.85, respectively, for V343 Aql and 33.0y, 0.0037d and 0.64, respectively, for CX Aqr. The properties of the third bodies suggested in V343 Aql and CX Aqr systems were discussed.

Among recent issues emerging in the areas related to the society, health has received the most attention. In this paper, for a patient unable to do self-care because of worsened diseases, a biological information transfer method is proposed by which the disease information can be securely managed, by attaching an implantable device into the body. Our method object of the invention is to prevent a third party from illegally intercepting and interfering with the biological information attached to the insertion device in the body. In the proposed technique to improve the safety of the patient between the hospital and physician by assigning each code to the biometric information of the patient in order to prevent a third party tapping and interfering. In addition, our method is assigned a code necessary for encoding in advance to confirm the biological information between the patient and the hospital (doctor) in a manner dividing the bio-information code. In particular, the proposed technique makes a third party unable to illegally tap or interfere in, by previously generating a code used for encoding so that it can be stored in the database of the hospital, which not only decreased hospital care time to 6.9%, but also increased work efficiency rate up to 12.7%.
