Objectives: This study analyzed the effects of diabetes interventions published in journals of nursing, medical and public health, to suggest directions for future research. Methods: A comprehensive search of three databases was undertaken (Korean studies, Riss4U, RICHIS) using research terms such as "diabetes", "nursing", "public health", "intervention" and "program". One hundred fifty four original articles were retrieved and 21 articles were finally analyzed. The analyzed articles satisfied the inclusion criteria and their effect size was calculated. Results: Most studies about diabetes intervention were published form 2001. 2005 (57.1%). The psycho-social variables, 'self-efficacy' and 'self-care' presented good effects on exercise or exercise prescription intervention. In addition, the physiological variables, 'fasting blood sugar' and 'glycosylated glucose' presented good effects on the interventions using four more elements or the interventions held in a public health center. Conclusion: Further research should consider the essential elements that benefit diabetes patients' behaviors or physiological indicators.

Objectives: The purpose of this study was to evaluate the effects of Baekyeum (BKE) on intestinal motility. Methods: The effects of BKE on intestinal motility at the physiological state were evaluated by determination of intestinal motility after administration of a charcoal meal. The effects of BKE on intestinal motility at cabachol-induced activated state and loperamide induced suppressed state were also evaluated by determination of intestinal motility after administration of charcoal meal. Results: BKE didn't affect the intestinal motility in physiological state, and BKE didn't affect the intestinal motility at the carbachol-induced activated state. BKE activated significantly the intestinal motility at the loperamide-induced suppressed state. Conclusions: It can be concluded that BKE is an effective herbal prescription for cancer-patients with gastrointestinal dysfunction, especially intestinal stasis.

The effects of ginseng on the penetration of glucose into Saccharomyces cerevisiae were studied by determining the amount of glucose in the supernatant of the glucose broth medium in which some dose of water extracts of ginseng or saponin were added and the yeast was cultured for 1 hour. 1. In the 1 hour culture with 0.04%, 0.08%, 0.16%, 0.32% and 0.64% dry ginseng glucose broth medium, the penetration rate of glucose into yeast was increased 4.76%, 7.96%, 10.09%, 9.08% and 7.48% respectively. 2. In the 1 hour culture with $10^{-6}%,\;10^{-5}%,\;10^{-4}%,\;10^{-3}%,\;and\; 10^{-2}%$ of saponin glucose broth medium, the penetration rate of glucose into yeast was increased 3.05%, 6.57%, 5.595, 4.44%. and 2.87% respectively. 3. Since the highest increasing percentage of penetration of ginseng and saponin were 10.19% and 5.89% respectively, the increasing rate of the ginseng was about twice that of the saponin. Therefore it could be concluded that the saponin contained in ginseng and other unkown components of ginseng affect the cell permeability.

Mulberry extracts can be incorporated into skin-whitening products. The compound attributed to lighten the skin is arbutin, a form of hydroquinone that inhibits melanin release by suppressing the tyrosinase enzyme. For the cosmetic applications, the physiological effects of mulberry (Morus alba) extracts were investigated. The water soluble fraction of mulberry contains higher amount of protein (16.28~4.47%) in contrast to fat (1.55~1.41%). In addition, the fraction abundantly contains succinic acid (972.4-275.8 mg/g) and phosphoric acid (1,628.4-121.9 mg/g) in different parts of mulberry. The free radical scavenging ability in water soluble fraction was found to display remarkable effects in comparison with methanol and ethyl acetate fraction. The ethyl acetate-soluble of root and leaf showed remarkable tyrosinase inhibition activity by IC 50 (${\mu}g/ml$). The anticancer activity of methanol fraction obtained from mulberry using human cancer cell lines showed growth inhibition effect (270.14 mg/ml in Calu-6 cells, 295.29 mg/ml in HCT-116, and 332.29 mg/ml in MCF-7 cells, respectively). Based on the results, Morus alba extracts include cosmetic ingredients with antioxidizing and whitening properties.

Purpose: The aims of this study were to construct a hypothetical structural model which explains premenstrual coping in university students and to test the fitness with collected data. Methods: Participants were 206 unmarried women university students from 3 universities in A and B cities. Data were collected from March 29 until April 30, 2016 using self-report structured questionnaires and were analyzed using IBM SPSS 23.0 and AMOS 18.0. Results: Physiological factor was identified as a significant predictor of premenstrual syndrome (t=6.45, p<.001). This model explained 22.1% of the variance in premenstrual syndrome. Psychological factors (t=-2.49, p=.013) and premenstrual syndrome (t=8.17, p<.001) were identified as significant predictors of premenstrual coping. Also this model explained 30.9% of the variance in premenstrual coping in university students. A physiological factors directly influenced premenstrual syndrome (${\beta}=.41$, p=.012). Premenstrual syndrome (${\beta}=.55$, p=.005) and physiological factor (${\beta}=.23$, p=.015) had significant total effects on premenstrual coping. Physiological factor did not have a direct influence on premenstrual coping, but indirectly affected it (${\beta}=.22$, p=.007). Psychological factors did not have an indirect or total effect on premenstrual coping, but directly affected it (${\beta}=-.17$, p=.036). Conclusion: These findings suggest that strategies to control physiological factors such as menstrual pain should be helpful to improve premenstrual syndrome symptoms. When developing a program to improve premenstrual coping ability and quality of menstrual related health, it is important to consider psychological factors including perceived stress and menstrual attitude and premenstrual syndrome.

The purpose of this study was to determine the effect of dance sports on physiological variables, depression and quality of life in the elderly. The study was performed on a non-equivalent control group pretest-posttest design for 47 elderly, who were conveniently assigned to experimental group and control group. The experimental group were selected from D-welfare facility and the control group were selected from G-elderly church club in G-city. The data were collected from April 2, 2001 to June 30, 2001, and analyzed by frequency, $x^2$-test, t-test and paired t-test using SAS/PC program. The results of this study were summarized as follows; 1. The first hypothesis, "the experimental group would have improved physiological variables than the control group.". 1-1. The hypothesis, "the experimental group would have lower blood pressure than the control group" was rejected. 1-2. The hypothesis, "the experimental group would have lower heart rate than the control group" was supported(t=-2.031, p=0.048). 1-3. The hypothesis, "the experimental group would have higher peripheral vessel $O_2$ Saturation than the control group" was rejected. 2. The second hypothesis, "the experimental group would have lower depression score than the control group" was supported(t=2.832, p=0.006). 3. The third hypothesis, "the experimental group would have higher quality of life score than the control group" was supported(t=2.604, p=0.012). After 12 weeks of dance sports program, it was shown that the program was effective to improve the physiological varibles, reduce depression and improve quality of life.

Background and Aims : Nerve conduction study is invaluable in clinical neurology, especially for assessing peripheral neuropathies. Abnormal nerve conduction studies may result not only from peripheral nerve dysfunction itself, but also from other various mechanical, technical, and physiological factors such as age, sex, height and temperature. So we conducted this study to establish the our own normal values. Methods : In this study, from March. 1997 to July. 1998, 40 Korean adults among person came to Health Promotion Center over the age of 20 without any suspicion of neurological deficits were analysed to determine the effect of compound effects of several physiological factors. Results : The nerve conduction velocities of the upper extremity and proximal segments were faster than those of the lower extremity and distal segments. Physiological factors such as age, height and temperature affect the results of nerve conduction studies in multiple regression analysis. The sex difference is recognized over peroneal motor nerve. There are no sex differences in amplitude transformed into normal distribution. The significant physiological factor affecting the amplitude of nerve conduction is age, whereas height and temperature play no role. Conclusions : In multiple regression analysis, height is widespread variable for the nerve conduction velocities and temperature is important variable for lower extremities. The parametric statistical analysis cannot be applied to the amplitude of the compound muscle or nerve action potentials because of marked left shift in distribution. Sqareroot transformation of the CMAP and CNAP may be useful in normalizing the distribution. The most significant physiological factor affection the amplitude is age. Sex differences are not seen in nerve conduction study.

Psychoacoustic characteristics of automobile horns play significant role in resulting subjective evaluation and psychphysiological reactions. However, comparison and differentiation of physiological responses to commercially available horns is a complicated task due to the small contrast in technical features of horns and the influence of such processes as habituation on physiological outcome with the increased number of auditory stimulation trials. In a study on 10 college students, there was performed comparative analysis of reactivity of physiological responses mediated by central and autonomic nervous systems in order to identify the role of habituation on decrement of psychophysiological responsivity and assess the ability to differentiate subjectively most and least preferred, as well as most and least appropriate horns according to physiological manifestations. The EEG and autonomic responses to 7 automobile horns were analyzed during 3 blocks of trials, with varying order of stimuli and changed acoustic parameters of horns in each block. Thus, responses were analyzed for totally 21 trials of auditory stimulation. It was shown that electrodermal and cardiovascular responses have different reactivity patterns to repeated stimulation: skin conductance measures habituated, cardiac reactivity showed no signs of habituation, and the vascular response demonstrated sensitization. The temporal EEG exhibited marked habituation of fast beta band power, while alpha-blocking effect did not habituate during the course of experiment. Differentiation of physiological responses of most and least preferred and appropriate horns was possible in our study, however, some cardiovascular reactivity measures differentiated during the entire course of the experiment, while EEG and electrodermal parameters showed significant differences only during first block of trials, and were later affected by the habituation.

Ozone ($O_3$) is a main component of photochemical oxidants, and a phytotoxic anthropogenic air pollutant. In North America and Europe, the current concentration of $O_3$ has been shown to have significant adverse effects on vegetation. In this review, we summarize the experimental studies on the effects of $O_3$ on the growth and photosynthetic activity of Japanese forest tree species to understand the present knowledge and provide sound basis for future research toward the assessment of $O_3$ impacts on Japanese forest ecosystem. Since the 1990s, several Japanese researchers have conducted the experimental studies on the effects of ambient levels of $O_3$ on growth and physiological functions such as net photosynthesis of Japanese forest tree species. Although the sensitivity to $O_3$ of whole-plant growth is quite different among the species, it was suggested that the current ambient levels of $O_3$ in Japan are high enough to adversely affect growth and photosynthetic activity of Japanese forest tree species classified into high $O_3$ sensitivity group such as Japanese beech. The N load to soil has been shown to reduce the sensitivity to $O_3$ of Japanese larch and increase that of Japanese beech. To establish the critical level of $O_3$ for protecting Japanese forest tree species, therefore, it is necessary to take into account the N deposition from the atmosphere. There is little information on the combined effects of $O_3$ and other environmental factors such as elevated $CO_2$ and drought on growth and physiological functions of Japanese forest tree species. Therefore, it is necessary to promote the experimental study and accumulate the information on the combined effects of $O_3$ and any other abiotic environmental factors on Japanese forest tree species.

Soil environmental conditions can affect nutrient availability during growth stage of tree fruit. We investigated the cause of disorderd fruit by the influence of soil chemical properties in orchard soil, composition of mineral nutrient in leaves and fruit to occur physiological disorderd fruit at four locations (Ulsan, Gyeongju, Pyeongtaek, Ansung) compared to healthy. There were significantly different (P=0.05) in exchangeable Ca, K, Mg and total nitrogen content in orchard soil between physiological disordered fruit and healthy fruit. The exchangeable Ca content in orchard soil caused by physiological disordered fruit was statistically lower than that of healthy fruit. However, exchangeable K, Mg and total nitrogen contents were higher than that healthy (P=0.05). There was a significant difference (P=0.05) in Ca content between physiological disordered fruit and healthy. Ca content in fruit flesh of physiological disorderedfruit was statistically lower than that of healthy. The physiological disordered fruit was a higher ratio of Mg/Ca in fruit flesh and peel compared to healthy fruit and also the ratios of N/Ca and K/Ca in a leaf were higher. The negative correlation between Ca and K, and Ca and Mg was detected in the fruit flesh of physiological disordered fruit. Therefore, we concluded that insufficient Ca content in fruit may cause 'the physiological disorder' pomelo disease and high content of N, exchangeable K and Mg ion in the soil solution might be disturbs exchangeable Ca ion to be absorbed in fruit.
