This study was conducted to investigate psychological and physiological changes of elderly affected by agro-healing activities. To meet the purpose, we conducted an agro-healing program with 20 elderly participants (average age 77.6±5.84 men and women) and once a week in total seven sessions. The Korean version of the Brief Encounter Psychosocial Instrument (BEPSI-K), Korean version of the Short Form of Geriatric Depression Scale (SGDS-K), participants' satisfaction with the program, Salivettes system method, and blood pressure were measured to find out the effects of agro-healing activities. BEPSI-K decreased by 5% in the high stress group although it was not statistically significant. The result of program satisfaction showed that 75% of the participants are satisfied with these activities. We investigated how many and what kind of chronic diseases the participants have had before they joined the program. As a result, hypertension was most common(35.6%), followed by hyperlipidemia, diabetes, arthritis, lumbago, osteoporosis, and heart disease. Systolic blood pressure after the activities decreased significantly from 144.75mmHg (stage 1 hypertension), to 132.90mmHg(prehypertension stage). As a result of analyzing the correlations between general matters such as age, education level, average income of the participants, psychological scale and number of diseases, it was found that participants' satisfaction had a negative correlation with depression. In conclusion, agro-healing is very useful in relieving stress or lowering blood pressure for the elderly whose most common disease is hypertension. Agro-healing activities are proved to have positive uses in reducing the problems of the modern society with severe issues of the aging population.

This study was presented to the physiological activities such as metal chelating capacity, superoxide dismutase-like activity, anti-inflammation, cytotoxicity from Zanthoxylum schnifolium fruit. The values for metal chelating capacity of 1 mg/mL of 70% EtOH and 70% MeOH extracts were 68% and 67%, respectively, it was shown that metal chelating capacity in a dose-dependent manner. The 100% EtOH and 100% MeOH extract exhibited strong superoxide dismutase-like activity. The highest SOD-like activity obtained from 100% EtOH was 51% at a concentration of 4 mg/mL. The all extracts of Zanthoxylum schnifolium fruit except $H_2O$ extract significantly decreased the concentration of LPS-induced NO in Raw 264.7 cells. The 100% EtOH, 100% MeOH and 70% EtOH extract represented the highest activity in the anti-inflammation properties in vitro. However, the 100% EtOH and 100% MeOH extracts has cytotoxicity in Raw 264.7 cells and it may affect cell viability. Conclude that 70% EtOH extract was most suitable for anti-inflammation. Our results revealed that the Zanthoxylum schnifolium fruit expected to physiological activities.

Light is a synchronizing stimulus to regulate the circadian rhythms and neuroendocrine activities in both humans and animals. The retinohypothalamic tract is involved in the day/night cycle and neuroendocrine activities. In particular, melatonin secretion has been known to be affected by light and correlated with many aspects of health problems. This review introduces the role of the light in the biological rhythm and neuroendocrine activities, its relationship with health problems, and the characteristics of retinohypothalamic tract.

This study investigated physical and physiological changes of normal young adults, who are cadets of the Air Force Academy, have kept long-term physical activities and healthy behavior. The physical and physiological indices were the blood and body composition. Data were collected at the first year period, and then 4th year period from same group of cadets. The amounts of blood components were not changed, but variation among cadets was significantly reduced in the 4th grade period. The red blood cells(RBCs) were significantly reduced and the concentration of hemoglobin(HGB) were significantly increased. The body weight was significantly decreased in the 1st grade period since the body fat was rapidly decreased after the basic military drill, and then it was recovered with building up of the skeletal muscle in the 4th grade period. Asymmetry of the arms was decreased with the increased physical activities and usage of various equipments. The muscular endurance were significantly enhanced in the 4th grade period. The long-term physical activities and healthy behaviors may keep the physical strength through enhanced blood stream and oxygen supply by reduction of the RBCs and increased HGB concentration, and fat and muscle control.

Purpose: This study was done to identify the Domains, Classes, labels and nursing activities of nursing interventions used with 117 patients who were admitted to orthopedic nursing units. Method: Data were collected in January and February, 2004 using a computerized nursing process program that contained nursing diagnosis-outcome-intervention (NNN) linkages. The program was developed by the researcher. Frequencies and percentages were used in the analysis. Results: Sixty-five nursing intervention labels were identified. The Domains of the nursing interventions showed higher percentages for 'physiological: basic' (75.9%), 'physiological: complex' (12.9%), 'behavioral'(7.8%) 'family'(1.3%), and 'safety'(1.1%). The Classes of nursing interventions showed higher percentages for 'activity and exercise management'(30.8%), 'physical comfort promotion'(19.3%), 'immobility management'(14.5%), 'drug management'(8.1%), and 'coping assistance'(5.6%). Nursing intervention labels showed higher percentages for 'pain management'(14.7%), 'body mechanics promotion'(8.0%), 'exercise therapy : ambulation'(7.2%), 'splinting'(5.4%), and 'positioning'(5.1%). In the comparison of numbers between performed nursing activities and nursing activities of NIC according to nursing intervention label, the mean of combined rate was 52.3%.

Paulownia coreana is a medicinal, edible and industrial plant with the largest leaf, and is native to Korea. We evaluated the reducing power activities, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities (RSAs), nitrite scavenging activities (NSAs) and 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) cation RSAs by solvent extraction of P. coreana bark by using $50^{\circ}C$ hot water and $25^{\circ}C$ methanol. The antioxidative effect of P. coreana bark extract on corn seed oil was evaluated using the Rancimat test. The extraction yields on dry weight basis with 15 folds of hot water and methanol were 23.88% and 5.30%, respectively; further the flavonoid content in the hot water extract was over 2.5 times more than that in the methanol extract. The DPPH RSA of the methanol extract was substantially higher than that of the water extract, whereas the NSA of the water extract was higher than that of the methanol extract at pH 1.2. The ABTS RSAs of the two extracts were almost the same as that of ascorbic acid and 2,6-ditertiarybutyl hydroxytoluene. The two extracts of P. coreana bark in this study were found to slightly improve the oxidation stability of corn seed oil.

This study was investigated to evaluate the contents of polyphenols and flavonoids, and physiological activities of various extracts from Calystegia japonica roots for making good use of their functional materials. The roots of C. japonica were extracted with water (WE), ethanol (EE) and hot water (HWE) by different methods. Among these extracts, the highest extracting yield was 30.30% of HWE, while the highest contents of total polyphenols and flavonoids were 40.85% and 6.40% of WE, respectively. The nitrite scavenging abilities were ranged from 31.31% (HWE) to 37.46% (EE) at pH 1.2 and 1.0 mg/ml concentration. In the measurements of electron donating abilities, EE showed the highest effect as 91.83% at 0.3 mg/ml assay concentration, and the electron donating ability was decreased as the extract concentration was increased. In the results of superoxide dismutase (SOD)-like activity, HWE showed the highest effect as 7.15% at 1.0 mg/ml. The tyrosinase inhibition activities of WE and EE were 15.28% and 14.97%, respectively. The xanthine oxidase inhibitory effects were ranged from 97.50 to 99.28% at 1.0 mg/ml. These results indicate that C. japonica extract has a good antioxidant effects and could be useful for developing functional products.
