This study was conducted to obtain accurate data on intake, apparent digestibility and nitrogen balance of dietary protein which the korean take in habitually. Subjects were 8 male college students, aged from 20 to 26, and maintained their menu and life pattern as usual during a 4-week study. The same amount of diet that the subjects had consumped, and feces and urine were collected and measured to extract their nitrogen content data by Kjeldahl method. From above data, the apparent digestibility and the body nitrogen balance were estimated by determining daily protein intake and excretion. The daily protein intake measured by Jjeldahil method was 88.3$\pm$ 0.9g(1.45/kg of body weight /day) which marked 8.3% higher than that estimatd by food analysis table. The proportional of animal protein against total protein intake was 50.4$\pm$ 2.3%. Daily fecal protein loss was 14.3$\pm$0.6g and the apparent digestibility was 83.8$\pm$ 0.7%. The urinary nitrogen excretion was 10.30$\pm$0.19g. The nitrogen balance considering nitrogen excretion from feces indicated positive balance of 1.06$\pm$0.20g.

Background : Methods of wearing a baby carrier have suggested; however, there have been no studies suggesting ideal ways. Objective : To investigate muscular fatigue and balance of the waist during baby carrier are worn on the front, the side, and the back of the body. Design: Randomized controlled clinical trial (single blind) Methods : The subjects of this study were 20 healthy men and women in their 20s, who underwent tests of muscular fatigue and balance of the waist bones based on types of wearing baby carrier. Electromyogram (EMG) patches were attached to the L2 and the L4 for testing muscular fatigue, while a device for measuring proprioceptive senses was used to assess balance ability. The measurements were performed before wearing the baby carrier and after 30 minutes of normal walking. The methods of wearing the baby carrier included wearing on the front, the side, and the back of the body. Results : The time taken to adjust the balance was shorter than other types of wearing during the baby carrier were worn on the side, and the ratio of lumbar flexion and relaxation was shown insignificant. Conclusions : These results suggested that wearing the carriers on the side was most effective on reducing fatigue and enhancing balance ability of the waist.

Purpose: The purpose of this study was to prove the effects of the PNF patterns combined with whole-body vibration (PWBV) training on muscle strength, balance, walking speed, and endurance in stroke patients. Methods: Sixteen subjects were randomly assigned to the PWBV group (n=8) and the whole-body vibration (WBV) group (n=8). The PWBV group performed PNF pattern exercises using sprinter combined with WBV, while the WBV group performed using squatting for 30 minutes. Both groups performed therapeutic interventions five days per week over a period of four weeks. The manual muscle test, timed up and go test (TUG), 10-meter walk test (10MWT), and six-minute walk test (6MWT) were used to assess the muscle strength, balance, and gait of the participants. The SPSS Ver. 19.0 statistical program was used for data processing. Statistical analysis included a pared t-test to compare the pre- and post-intervention, and an independent t-test was used to compare groups. The significance level was set as 0.05. Results: The PWBV group and WBV group showed significant improvements in the TUG, 10MWT, and 6MWT (P<0.05). Significant differences between the PWBV and WBV groups were found (P<0.05). Conclusion: The PWBV improved muscle strength, balance, gait speed, and endurance in stroke patients. Thus, PWBV may be suggested as a therapeutic intervention in patients with stroke hemiplegia.

In the present study, we investigated the physiological effects of smartphone use at night when the display luminance and white balance were differently manipulated. Two levels of luminance and two types of white balance were combined to form four types of displays. Subjects were instructed to use smartphones between 23:00 to 01:00 twice a week for two weeks, and for each trial, subjects were given one of the four display types. Melatonin concentration in the saliva, body temperature and heart rate were measured before and after each experiment. The experimental result showed that the low luminance display supported melatonin secretion and thermoregulation compared to the high luminance display. With regard to the white balance, higher melatonin level was observed when using the display that filtered blue light. The low luminance display together with yellowish tint best supported restful sleep at night in terms of every physiological response. This study collectively demonstrates that bright and blue light emitted from smartphone displays adversely affect melatonin secretion, body temperature, and heart rate, and therefore, suggests the use of a display with low luminance or a display that filters blue light for a restful sleep at night.

Stance is defined as any state in which the total mass of the body is supported by the feet. In order to maintain stance, the sum of gravito-inertial forces acting on the body must be registered by equal and opposite forces at the region of contact between the organism and the support surface. Balance is controlled by applying forces to the surface of support so as to maintain the body's center of mass vertically above the feet. for a muIti-segment organism, there can be a variety of ways in which balance can be controlled, since movements of different body segments can have similar effects on the control of balance. In general, the organism tends to have a body configuration that is aligned with gravito-inertial force when there are no external forces acting on it. If any segments of the body are not aligned with gravito-inertial force vector, a torque on that segment would tend to move the body's center of mass. The maintenance of postural stability is accomplished in humans by a complex neural control system. This requires organizing integrating and acting upon visual, vestibular, and somatosensory input, providing orientation information to the postural control system. The information necessary to control and coordinate movement is provided by the visual sense of eye position with respect to the surrounding surface layout, the vestibular sense of head orientation in the gravito-inertial space, and the somatic sense of body segment position relative to one another and to the support surface. In this study, perception and action capability was examined from various points of view. The underlying assumption of the study was that the change of postural configuration could be effected by organism, environment and task goal.

본 연구는 항콕시듐 제제로 광범위하게 쓰이고 있는 nicarbazin이 닭의 고온 스트레스에 미치는 영향을 조사하고자 16수의 SCWL 수탉 성계를 사용하여 실시하였다. 옥수수-대두박 위주의 사료에 두 수준(0 및 125ppm)의 rucarbazin을 첨가하여, 두 처리의 환경온도(21 와 35~$36^{\circ}C$)하에서 4일간의 예비실험 기간을 거친 후, 2일 동안의 시료 및 자료 수집기간을 가졌다. 건물 섭취량과 건물 배설량은 고온 스트레스에 의하여 유의한 영향을 받지 않았으나, ricarbazin 첨가에 의하여 증가하였다. 그러나 건물 대사율은 nicarbazin첨가에 의하여 유의하게 감소하였다. 고온 스트레스는 또한 음수량과 증발에 의한 수분 손실을 증가시켰고, nicarbazin은 이러한 효과를 더욱 심화시켰다. 혈액 pH는 고온하에서 nicarbazin 첨가에 의해 증가되었으며, p$CO_2$는 고온하에서 nicarbazin에 의해 감소되었다. 고온 스트레스는 또한 체온을 상승시켰으며 nicarbazin 첨가는 이러한 효과를 심화시켰다. 이상의 결과를 종합하면, 닭이 고온 스트레스를 받으면 체온이 상승하게 된다. 따라서 닭은 체온 상승을 억제하기 위하여 호흡수를 증가시켜(panting) 수분 증발을 통한 체열 방출을 많게 한다. 그러나 nicarbazin 첨가는 고온하의 수탉 체온 상승 폭을 워낙 크게 하므로, panting에 의한 체열 방출량 증가만으로는 정상 체온을 유지하기가 어렵게 되는 것으로 풀이된다
