Now a days, frequency of abnormally high temperatures like heat wave by global warming and climate change is increasing constantly and the number of patient with heat related illness are jumping rapidly. In this study, we chose the case day for the heat wave in Busan area(Busan and Yangsan), 2013 which it was the most hottest year during 21th century. And then, we analysed the weather condition using automatic synoptic observing system(ASOS) data. Also, four indices, heat index(HI), wet bulb globe temperature(WBGT), Man-ENvironment heat EXchange model(MENEX)'s results like Physiological subjective temperature(PST), Physiological strain(PhS), were calculated to evaluate the thermal comfort and stress quantitatively. However, thermal comfort was different as the each station and thermal comfort index during same time. Busan's thermal indices (HI: hot, WBGT: sweltering, PST: very hot, PhS: very hot) indicated relatively higher than Yansan's (HI: very hot, WBGT: sweltering, PST: very hot, PhS: sweltering). It shows that Busan near coast is relatively more comfortable than Yangsan located in inland.

The present study elucidated the growth properties of Sasa borealis communities distributed in the lower layer of deciduous broadleaf forests in temperate zones and analyzed the correlation between the growth properties of S. borealis and positional environmental factors. The higher the culm height of S. borealis was, the higher the values of the leaf number, leaf area, and foliage layer thickness became. This might be because as the culm height of S. borealis increased, the acquisition of light sources became easier so that the biomass of leaves increased simultaneously for smooth anabolism. S. borealis seem to change their growth mode for smooth acquisition of light resources. The culm density of S. borealis and the leaf number, leaf area and foliage layer thickness of S. borealis did not show any clear correlation. The values of the culm height, leaf number, leaf area, and foliage layer thickness of S. borealis as the above altitude of the location of S. borealis increased. It seems like that growth conditions such as temperatures and winds are deteriorated as the above altitude of the location of S. borealis increased so that S. borealis becomes smaller. No clear correlations were shown between the physiochemical properties of soil and S. borealis' growth properties. It seems like that the growth of S. borealis complexly intertwined with diverse environmental factors and that due to the physiological integration of S. borealis, certain physiochemical properties do not unilaterally affect S. borealis' growth properties.

The purpose of this study is to determine the effects of exercise programs on the treatment of chronic diseases. For this purpose, nine middle-aged women suffering from such chronic diseases as obesity, hypertension and coronary heart disease(CHD) were sampled to perform a 4-month-long exercise program which required the lactate threshold(LT) level corresponding to 70% of maximal oxygen uptake(VO2max). Thereupon, their physiques, physical fitness, blood components and physiological varibles were compared pre and post of exercise program. The results were summarized as follows ; 1) After the 4-month-long exercise program, %fat was significantly decreased, while such variables as grip strength, side step, trunk flexion and leg balance were significantly increased. 2) Blood components such as TG, TC, HDL-C, LDL-C, hemoglobin and hematocrit did not show and change in after exercise program. 3) Physiological varables such as HR, SBP, DBP, HR/LT, SBP/LT, DBP/LT, RPE/LT, VE/LT, VO2/LT and VO2 max showed significant increase after 4-month exercise program. These results suggest that regular aerobic exercise in a long period might help to decrease % fat and to increase aerobic capacity in middle-aged women suffering from chronic diseases.

Diarun plus, a polyherbal formulation containing herbal ingredients of folkloric Antidiabetic effect, was investigated for its effect on glycemic status in rats and mice. In contrast to conventional chemical induced diabetic animal models, changes in glycemic states were induced by physiological maneuvers. Results revealed that in euglycemic animals Diarun plus elicited little change (-10 to +10%), which was insignificant. In food deprivation/swim exercise induced hypoglycemia, Diarun plus reduced the degree of hypoglycemia in both rats and mice (from 38% to 27% in rats and 45% to 32% in mice). Similarly, the marked hyperglycemia induced by dextrose (70% in rats and 95% in mice) was reduced markedly to 8% and 25% respectively. The findings of the present study suggests that the ingredients of Diarun plus have the unique property of maintaining near euglycemic state irrespective of the altered glycemic state, and that have no significant effect in euglycemic condition.

Mechanisms of insecticide resistance found in insects may include three general categories. Modified behavioral mechanisms can let the insects avoid the exposure to toxic compounds. The second category is physiological mechanisms such as altered penetration, rapid excretion, lower rate transportation, or increased storage of insecticides by insects. The third category relies on biochemical mechanisms including the insensitivity of target sites to insecticides and enhanced detoxification rate by several detoxifying mechanisms. Insecticides metabolism usually results in the formation of more water-soluble and therefore more readily eliminated, and generally less toxic products to the host insects rather than the parent compounds. The representative detoxifying enzymes are general esterases and monooxygenases that catalyze the toxic compounds to be more water-soluble forms and then secondary metabolism is followed by conjugation reactions including those catalyzed by glutathione S-transferases (GSTs). However, a change in the resistant species is not easily determined and the levels of mRNAs do not necessarily predict the levels of the corresponding proteins in a cell. As genomics understands the expression of most of the genes in an organism after being stressed by toxic compounds, proteomics can determine the global protein changes in a cell. In this present review, it is suggested that the environmental proteomic application may be a good approach to understand the biochemical mechanisms of insecticide resistance in insects and to predict metabolomic changes leading to physiological changes of the resistant species.

Purpose: This study was done to examine the effects of moxibustion on physiological indices, such as 24-hr blood pressure, pulse pressure, and pulse rate, and autonomic nervous symptoms among adults with prehypertension. Methods: Participants were adults whose systolic and diastolic blood pressures were in the prehypertension stage and were not under treatment for the condition. Both experimental and control group consisted of 13 participants who were taking classes on acupuncture and moxibustion at a private institute. The experimental group received moxibustion once a day for 15 min, at least 5 days a week for 8 weeks. The results were analyzed using $x^2$-test, t-test, Fisher's exact test, Wilcoxon rank sum test and repeated measures ANOVA with the SAS program. Bonferroni correction method was adopted for multiple comparisons. Results: No significant change was observed in the 24-hr systolic and diastolic blood pressure between the two groups. Differences in the 24-hr pulse pressure and pulse rate were also not significant. However, significant decreases in headache, symptoms of flushing and fatigue were observed in the experimental group. Conclusion: The results suggest that moxibustion contributes to alleviating symptoms such as headache, flushing and fatigue associated with the autonomic nervous system among adults with prehypertension.

The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants (Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae frutcus) and we examined the effects of drink on physiological response during exercise and recovery phase. The subjects were male baseball players, and exercise protocol was performed with 45 minutes treadmill running and 85％ VO$_2$ max intensity. Brix, pH and titratable acidity of developed drink were 9.5％, 3.3 and 0.22％. The approximate nutritional composition of beverage was carbohydrate, 5.98％, total dietary fiber, 0.42％, crude protein, 0.70％, crude fat, 0.20％ and crude ash, 0.20％. Developed. traditional functional beverage contained K (4.00 mg％), Na (3.68mg％), Ca (2.54mg％), Mg (1.60mg％) and Fe (0.29mg％). Developed beverage drinking group showed a lowest heart rate during exercise and recovery phase than the other two group (water group and ion beverage group). In the change of blood lactate concentration, developed beverage intake group showed a significant lowest values during exercise and recovery phase. And blood hematocrit values and osmolarity were lowest in the developed beverage intake group. In these results, exercise performance capacity was expected to improve most highly with the developed drink from composition with medicinal plants. Also developed beverage was effective in recovery of exercise-induced fatigue. Thus developed drink with medicinal plants can be used as a functional material improving decrease fatigue effects in beverage industry.

The histological changes of gill, liver, spleen and muscle, and respiration and blood variables and liver glycogen content were examined in black seabream, Acanthopagrus schlegeli. Fish were exposed to a high level of total ammonia nitrogen (10.4 mg/l) and recovered from exposure $(0.4{\pm}0.2mg/l)$ in a closed recirculating seawater system. In the process of exposure, mortality was $9\%$, and hyperplasia, necrosis or inflammation appeared in all tissues except for muscle. Oxygen consumption was decreased by $49\%$, and red blood cell (RBC) number, hematocrit and hemoglobin concentration were significantly decreased, while plasma glucose contents, activities of glutamate-oxaloacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT) increased. Liver glycogen content significantly increased from $6.6\%\;to\;10.4\%$. A large amount of hemosiderin was observed in the splenic tissue. During the recovery period, RBC number, hematocrit, hemoglobin concentration, GOT and GPT activities were returned to the normal status. Histological status of liver tissue was returned to the normal, but liver glycogen content was not recovered. During the recovery period, spleen melanin-macrophages temporarily increased, but subsequently decreased to the normal status.

Toes socks are used widely for the health of feet. However, discomfort is one of the major complains from toes socks users. The purpose of this study is to determine the effect of functional fibers on the physiological response and wearing sensation of toes socks. For experiment, two different toes socks with cotton/warm fiber(WS) and cotton/chitosan fiber(CS) were knitted automatically by a computer controlled flat knitting machine. The control toes socks with cotton/nylon/polyurethan(TS) were prepared to compare the properties. Experiments were conducted in a climate room of $16\pm2^{\circ}C$, $50\pm5%$ R.H. The results of this study were as follows. The change of heart rate, pulse rate, and mean skin temperature showed no difference among three different socks. However, skin temperature of TS was evaluated higher than that of WS and CS. After exercise wearing WS both instep temperature and sole temperature of women tend to higher compared to men. Wet sensation and overall comfort sensation of toes socks were significantly influenced by different fiber contents. Subjects evaluated WS and CS more comfortable than TS.
