This study optimizes a suitable dyeing method for polylactic acid (PLA) fabrics using disperse dyes. For this, disperse red 60 (DR 60), disperse blue 56 (DB 56), and disperse yellow 54 (DY 54) were used and dyed on PLA fabrics dependent of dyeing temperature and time. The fastness of PLA fabrics dyed with three disperse dyes were evaluated; in addition, dye exhaustion, color strength (K/S value), and colorimetric properties of PLA fabrics were compared with PET fabrics. The experiments indicated optimum dyeability of PLA fabrics with disperse dyes. The dyeing temperature was $90^{\circ}C$ for every dye and the dyeing time were 20 min, 60 min, and 40 min for DR 60, DB 56, DY 54, respectively. PLA fabrics had good color fastness to washing, dry cleaning fastness, hot pressing fastness, rub fastness, and perspiration fastness by DR 60, DB 56, and DY 54. The dye exhaustion of PLA fabrics were lower than PET fabrics; however, K/S values were higher than PET fabrics.

Objectives: We aimed to evaluate the effect of Cervi Cornu and coenzymeQ10 on exercise and endurance capacity in rats and mice. Methods: The extract of Cervi Cornu was manufactured by the pharmacy department of Kyung Hee Oriental Medical Hospital, and CoQ10 soft cap (Ildong Pharmaceutical) was used. In total, 24 rats and 30 mice were divided into 3 groups: Control (rat=8, mouse=10), CoQ10 alone (rat=8, mouse=10), Cervi Cornu extract, and CoQ10 (rat=8, mouse=10). Ergogenic effect was evaluated by administering the Cervi Cornu extract and coenzymeQ10 to rats and measuring the time to exhaustion during treadmill running; endurance capacity was assessed by measuring cold water swimming time, serum lactate level, and serum corticosterone level in each group. At 1 week from the end of treatment, we recalculated time to exhaustion during treadmill running in rats to investigate the long-term effect of the Cervi Cornu extract and coenzymeQ10. Results: Cervi Cornu extract has long-term benefits in that it preserves the ergogenic effect caused by exercise. Cervi Cornu and coenzymeQ10 have no effect on increasing cold water swimming time in ICR mice. CoenzymeQ10 decreases the serum corticosterone level in ICR mice performing cold water swimming test. Conclusions: Cervi Cornu seems to preserve the ergogenic effect caused by exercise, but a larger study is needed to investigate effect of Cervi Cornu and coenzymeQ10 on improving endurance capacity. CoenzymeQ10 decreases serum corticosterone level and it is related with the anti-psychological fatigue effect.

The purpose of this thesis is to investigate whether taurine supplementation in combination with fructose improves both energy metabolism and exercise capacity. Eight collegiate female subjects were recruited for the study. Each subject went through threecross-over designs: control(fluid), fructose, and taurine plus fructose supplementation trials. Subjects received taurine supplementation 100 mg/kg a day for two weeks. After the supplementation, all subjects take 10% fructose at 15 min prior to exercise, immediately before exercise, and every 15 min during exercise. Subjects received 150 ml fluid as placebo during the same procedure. The subjects performed submaximal exercise at the exercise intensity of 60% for 45 min and then 80% of maximal oxygen uptake (VO_2max) until exhaustion time. A 10ml blood sample was taken for measuring the level of glucose, ammonia, lactate, free fatty acids, and insulin every 15 min during exercise at 60% of VO_2max. The blood glucose levels was significantly higher at 45 min and 50 min exercise after supplementation of fructose, and immediately before exercise and 50 min exercise after taurine plus fructose compared to the placebo trial. However, the values tended to be lower in taurine plus fructose supplementation compared to the fructose trial. The levels of both lactate and ammonia were significantly lower compared to the placebo, while the exhaustion time was significantly increased. The level of free-fatty acids was significantly lower at 30, 45, and 50 min after fructoseand fructose plus taurine supplementation compared to the placebo trial. The level of glucagon was significantly lower at 15, 30, 45, and 50 min after fructose and fructose plus taurine supplementation compared to the placebo trial. There was no differences in insulin concentration among three treatments. This thesis concludes that combined taurine and fructose supplementation prior to exercise may improve exercise tolerance time and energy metabolism, lowering the muscle fatigue factors such as lactate and ammonia.

A wireless image sensor node collecting image data for environmental monitoring or surveillance requires a large amount of energy to transmit the huge amount of video data. Even though solar energy can be used to overcome the energy constraint, since the collected energy is also limited, an efficient energy management scheme for transmitting a large amount of video data is needed. In this paper, we propose a method to reduce the number of blackout nodes and increase the amount of gathered data by selecting an appropriate video coding method according to the energy condition of the node in a solar-powered wireless video sensor network. This scheme allocates the amount of energy that can be used over time in order to seamlessly collect data regardless of night or day, and selects a high compression coding method when the allocated energy is large and a low compression coding when the quota is low. Thereby, it reduces the blackout of the relay node and increases the amount of data obtained at the sink node by allowing the data to be transmitted continuously. Also, if the energy is lower than operating normaly, the frame rate is adjusted to prevent the energy exhaustion of nodes. Simulation results show that the proposed scheme suppresses the energy exhaustion of the relay node and collects more data than other schemes.

Wool fabric and merino wool top were dyed with two dyes, C.I. Acid Red 13 and C.I. Direct Blue 1 in presence of hydrogen peroxide/glyoxal redox system at various conditions such as dyeing time, temperature and redox concentration. The pH of dye bath was 4.5 in buffer solution of $KH_{2}PO_{4}$ (0.1mol/1)/$Na_{2}HPO_{4}$ (0.1mol/1). Also dyeing of cotton fabric was carried out with C.I. Direct Blue 1 in absence or presence of redox system. The color depth(K/S) increased with redox concentration and dyeing temperature. The increases in dyeing rate and equilibrium dye exhaustion of Acid Acid 13 and Direct Blue 1 on wool fiber and fabric in the present of hydrogen peroxide/glyoxal have been caused by decreasing in pH value during dyeing process which due to the decomposition of hydrogen ion in glyoxal with the assistance of hydrogen peroxide. But the decreases in exhaustion of Direct Blue 1 on cotton may be attributed to repulsive interac ion between salt and salt.

Increase in fat mobilization by capsaicin(CAP) was investigated in high-fat-fed mice using an adjustable current water pool. Male ICR 7-wk-old mice were fed a high fat diet [50% total energy content in the diet(E%) fat, 20 E% protein, 30E% carbohydrate] for 2 wk and one group (HCAP) was orally administered CAP at 2 h before swimming. After being accustomed to swimming , the mice were subjected to forced swimming every 2d in the current water pol and the total swimming period until exhaustion was measured . The total swimming period was used as index of swimming capacity. Swimming time to exhaustion of treated mice was significantly longer than that of the high-fat-fed control group (100.2$\pm$10.6 vs. 58.0$\pm$8.5min, P<0.01) after 2wk of training. The concentration of serum-free fatty scids gradually increased up to 2 h in CAP -administered mice. The perirenal adipose tissue weight of CAP -administered mice (HCAP) before swimming was lower than that of the high-fat-fed mice adminstered placebo solution (HP) which had not ingested CAP during the 2 wk. These results suggest that the increase of swimming capacity of CAP-administered high-fat-fed mice was due to an increase of fat mobilization that was induced by CAP.

Purpose: The aim of this study was to explain the burnout among health teachers in elementary schools with large class sizes, and to explore the nature and meaning of those experiences. Methods: This study used the four steps of Giorgi's descriptive phenomenology. Data were collected through in-depth interviews regarding the experiences of burnout of 9 participants, which were recorded, transcribed, and analyzed. Results: The participants' experiences of teaching large classes were categorized into 4 themes and 9 domains. The themes were "difficult and lethargic," "gradual deterioration conditions," "losing work-life balance," and "enduring for a short time and leaving." Conclusion: Burnout not only affected the teachers at work but also had a negative impact on the teachers' personal and family lives outside of school. This study found that the current teacher assignment criteria were the strongest factors influencing burnout, which contribute to physical exhaustion. Health teachers are assigned based on different criteria that do not consider the number of students. Another factor contributing to burnout among health teachers is a work environment conducive to with emotional exhaustion. Health teachers and content teachers are not sufficiently knowledgeable regarding the specifics of each other's work.

[Purpose] We determined the effect of partial sleep deprivation (PSD) after an exercise session on exercise performance on the following morning. [Methods] Eleven male athletes performed either a normal sleep trial (CON) or a PSD trial. On the first day (day 1), all subjects performed an exercise session consisting of 90 min of running (at 75% ${\dot{V}}O_{2max}$) followed by 100 drop jumps. Maximal strength (MVC) was evaluated before and after exercise. In the CON trial, the sleep duration was 23:00-7:00, while in the PSD trial, the sleep duration was shortened to 40% of the regular sleep duration. On the following morning (day 2), MVC, the metabolic responses during 20 min of running (at 75% ${\dot{V}}O_{2max}$), and time to exhaustion (TTE) at 85% ${\dot{V}}O_{2max}$ were evaluated. [Results] On day 2, neither the MVC nor ${\dot{V}}O_2$ during 20 min of running differed significantly between the two trials. However, the respiratory exchange ratio was significantly lower in the PSD trial than in the CON trial (p = 0.01). Moreover, the TTE was significantly shorter in the PSD trial than in the CON trial (p = 0.01). [Conclusion] A single night of PSD after an exercise session significantly decreased endurance performance without significantly changing muscle strength or cardiopulmonary response.
