This study conducted a survey and analysis of saliva cortisol and psychological questionnaire in order to find out the psychological and physiological changes according to the experience of the care farm targeting fire-fighters. In the program to experience care farms, the total cortisol concentration as a stress hormone decreased after participation, and there was a statistically significant difference (z = 2.858, p <.01). As a result of the risk distribution analysis of the level of post-traumatic stress symptoms of firefighting officials who participated in the program to experience care farms, the high-risk group was found to be as high as 31.2%. In addition, the relative explanatory power of the independent variables that influence the loyalty of the care farm experience activity was found to have an effect in the order of program satisfaction, age, and reliability, and among them, program satisfaction was found to be the most influential variable. Therefore, it is believed that the care farm experience activities as the application of the healing program will have a positive effect on the activation of care farms in each region and the relief of stress symptoms of fire-fighters.
The study was designed to assess the zinc nutritional status by gestational age of pregnant women visiting in public health centers in Ulsan. The subjects were divided into 3 trimester by last menstrual period(LMP). Interview for dietary zinc intake and general characteristics of each subjects was given and biochemical analysis of blood and urine was performed. Serum zinc concentration and urinary zinc excretion were analyzed by Flame Atomic Absorption Spectrophotometer, and alkaline phosphatase(ALP) activity was analyzed by Bowers & McComb\\`s method with Schimadzu automatic analyser. Also urinary creatinine was analyzed by Hawk\\`s method. Mean intake of zinc was 6.61${\pm}$1.57mg and did not meet the RDA(44.1% of RDA) for pregnant women by gestational age. Zn intake of 3rd trimester was significantly increased but dietary zinc was almost supplied with cereal and grain (47.30%) which were reported with low zinc availability due to phytate. Mean concentration of serum Zn in 1st trimester was 86.4${\pm}$10.5$\mu\textrm{g}$/dl, was 72.4${\pm}$10.3$\mu\textrm{g}$/dl in trimester and 65.1${\pm}$10.8$\mu\textrm{g}$/dl in 3rd trimester and was declined significantly by gestational age during pregnancy. In was concluded that a decline in serum Zn by gestional age was not influenced by amount of Zn intake. However ALP activity and urinary zinc excretion increased significantly by gestational age. Zinc nutritional status of pregnant women was not confirmed yet due to the physiological changes during pregnancy. However, the pregnant woman may be in a marginal zinc deficient status because of low amount of Zn intake and low bioavailability of Zn from dietary sources.

Background: Bronchial hyperresponsiveness (BHR), an important physiological feature of asthma, is a prognostic marker of childhood asthma. Purpose: We aimed to investigate the factors associated with BHR in adolescents with childhood asthma. Methods: Two hundred and fifteen adolescents (≥13 years of age; 149 males, 66 females) who were diagnosed with asthma during childhood were enrolled, underwent methacholine challenge tests, and were divided into the BHR group (<25 mg/mL of provocation concentration causing a 20% fall in forced expiratory volume in 1 second [FEV1] [PC20], n=113) or non-BHR group (≥25 mg/mL of PC20, n=102). We examined longitudinal changes in BHR and the risk factors for its persistence in the 108 adolescents for whom baseline data, including methacholine PC20 at age 6 years, were available. Multivariate logistic regression analyses were performed to assess the factors associated with BHR in adolescents. Results: Mold sensitization (adjusted odds ratio [aOR], 5.569; P=0.005) and increased blood eosinophil count (aOR, 1.002; P=0.026) were independently associated with BHR in boys but not girls. The odds of BHR decreased by 32% with each 1-year increase in age in boys (aOR, 0.683; P=0.010) but not girls. A reduced FEV1/forced vital capacity ratio (<90%) was independently related with BHR in female patients only (aOR, 7.500; P=0.007). BHR decreased with age throughout childhood. A low methacholine PC20 at age 6 years was independently associated with persistent BHR throughout childhood in male and female patients, whereas early mold sensitization was a risk factor for persistent BHR in male patients only (aOR, 7.718; P=0.028). Conclusion: Our study revealed sex-specific differences in the factors associated with BHR in adolescents with childhood asthma. Our findings suggest the risk factors that might affect asthma transition from childhood to adolescence and adulthood.
Purpose: This study was to investigate the effects of non-nutritive sucking on physiological and behavioral state of pre-term infants during tube feeding. Method: This nonequivalent, non-synchronized experimental study included 50 pre-term infants. An attempt was made to match gestational age and birth weight of infants in each group. Infants in the experimental group were given a pacifier 2 minutes before, during, and for 2 minutes after tube feeding. Infants in the control group did not get a pacifier. Both groups were tested at three stages for changes in the physiologic state and behavioral state - 2 minutes before, during, and 2 minutes after feeding. Date was analyzed with SPSS WIN 10.0 using an $X^2$-test, t-test, and repeated measures ANOVA. Result: Heart rates and oxygen saturation levels of the two groups were significantly different(P=.001, P=.000). The behavioral states of the two groups were significantly different during and post feeding(P=.000, P=.000). Conclusion: This result suggests non-nutritive sucking by using a pacifier is an effective intervention for pre-term infants during tube feeding.

This study was conducted to find out the effects of agro-healing activities and strolling on the physiological conditions of patients with chronic metabolic diseases. A total of 11 subjects participated in agro-healing activities, and their average age was 49.6±11.3. Changes in their salivary cortisol were compared and analyzed before and after participating in the agro-healing activity program, and it was found that the stress hormone decreased after participating in the program. Differences in brain wave between before and after participating in agro-healing activities and strolling were measured, and the ratio of alpha to high beta (RAHB) of subjects increased in most of the measured points after participating in agro-healing activities. In addition, the increase in the value in the temporal lobe (T3) that controls mortor skills and occipital lobe (O2) that controls visual functions indicates that the activities were effective in improving relaxation and stability. The relative low beta (RLB) power spectrum of subjects also statistically significantly decreased in the right occipital lobe (O2) that controls visual functions, the relative mid beta (RMB) and relative high beta (RHB) power spectrum decreased in the left temporal lobe (T3) and the right occipital lobe (O2). These results indicate that the activities were effective in improving relaxation under no stress and tension. The systolic and diastolic blood pressure of subjects after participating in agro-healing activities decreased from the prehypertension level to the normal level. These results indicate that horticultural activities and visual elements in healing farms, such as agro-healing activities and strolling, have positive impacts on patients with chronic metabolic diseases accompanied with diabetes or high blood pressure by increasing the brain activity and psycho-physiological conditions of participants.
The range of disorders of old age that are thought potentially amenable to drug therapy is increasing. However, factors such as the growing costs of drug development and prescription, the novel pharmacological profile and enhanced potency of many new compounds, and the concerns that the elderly may have enhanced susceptibility to toxicity all make drug usage in the elderly patient an increasingly specialized topic. This is compounded by the high incidence of multiple disorders in frail elderly patients, and consequently the possibility of the long term use of several drugs, thus, adding the risk of drug interactions. Thus, clinical pharmacology in the elderly requires understanding of pharmacologic characteristic determinants of the physiological changes (Table 1) associated with aging in terms of pharmacokinetics and pharmacodynamics.
Along with the recent changes in animal feed supply circumstances, many enzyme and probiotic feed supplements have been introduced and applied to pigs and chicken diets. Therefore, both selection of the appropriate feed supplements and their proper supplementation becomes critical to justify the supplementation. Meta-analysis was proposed as an appropriate tool to assess the large amount of relevant information. In this review, reliable data from recent publications was compounded then analyzed to determine the best practice of effective enzyme supplementation from the perspectives of animal species, age, characteristics of feed, target substrates, optimum multi enzymes combination and intended objectives. The results of the analysis suggested pratical methods of probiotic supplementation regarding intestinal microbiota, physiological limitation of probiotics, maximization of the probiotic benefit and synergism with prebiotic supplements.
Developmental changes of chlorophyll-protein (CP)-complex and plastid membrane proteins during the greening of rape (Brassica napus L.) cotyledons were examined in order to investigate the effect of benzymladenine (BA) on plastid development. The formation of CP-complexes was slightly promoted by BA treatment in early greening stage, at 24 h and 48 h after illumination. However, BA inhibited the development of CP-complexes at 72 h after illumination. On the profiles of plastid membrane proteins with greening time, it was found that the 24 kd protein was increased and the 56 kd protein was decreased in both water control and BA-treated cotyledons. However, the above two traits were retarded under BA treatment, respectively. From the obtained result, plastid development of rape cotyledon during greening was partially affected by interaction between light and BA dependent on its physiological age.
Before the current western medicine was spreaded out in the world as the main stream, each country had treated diseases with the medicine of their own and the traditional medical books, which are so characteristic, are handed down. Considering the earnest assignment to do in Korean medical of this age and one of the tendencies of medical circles in the world is putting together the current medicine with the traditional medicine, the production and spread of the classification system for the technical books which is contained the characteristic of traditional chinese medicine, the present condition of modern chinese medicine, and the future of it, must be settled without delay. The classification system for oriental medicine section developed in the range of the simple system before the time of flowering, since then the western medicine had grew as the main current in medicine in Korea. But until now the rational and realistic classification system based on the changeable time isn't be established, so setting up one of the classification systems for medicine section, it is classified according to the principle of classification system for medicine section. Hereupon, the result was made after researching the changes of modern classification system for korean and studying on the changes of classification system for oriental medicine section of the Korean decimal classification.
The effects of Physical exercise, gymnastics and sports on the cardiopulmonary function were studied in the middle and high school toys. The subjects were divided into 4 groups; non-training group and training group in both middle school and high school boys. In the above groups, pulmonary function studies were performed, and blood pressure and the heart rate were also checked to evaluate physical fitness during and immediately after running exercise on the tread-mill, with the speed of 5 MPH and elevation of 9% and 11.25%. The types of sports in the training group were base ball, body building, Taekwondo (Korean style boxing) and hand ball. The results obtained were as followings: 1) In the training group, cardiopulmonary function showed some tendency of the increase comparing to the non-training group. 2) The increase in cardiopulmonary function was observed according to the age became older, but the clear changes on cardiopulmonary function was not observed as the difference of the group between the training and the non-training. 3) The expiratory volume was decreased as the increase of age except 17 years of age for the value of the per kg body weight. 4) In the non-training group, the mean value of oxygen consumption under maximum work load was increased, while those in the training group was decreased. But it may be noted that oxygen consumption for the expiratory volume was increased in the training group, and that the oxygen cost in the training group was .higher than that of the non-training group. 5) The pulse pressure of the high school group during and immediately after running exercise was observed in the higher value comparing with that of the middle school group It was suggested that the changes of the pulse pressure was owing to the method of determination and that to the decrease of diastolic pressure caused by the decrease of peripheral vascular resistance up to critical closing pressure. 6) Any differences of the changes in the heart rate between the training group and non-training group was not observed during and immediately after running exercise. 7) The relative value of the expiratory volume to the heart rate was decreased in the elder age group.
