The purposes of this research are to examine the effects of muscle relaxation to the rheumatoid arthritis patients' physiological, psychological, and social adaptation, and to verify that the technique Is an effective tool for improving the patients' adaptation. This research utilized a qusi-experimental design that compares the pre-experiment measures and the post-experiment measures. The subjects of this study were 37 out-patients who were diagnosed for rheumatoid arthritis in P university hospital and K clinic between September 12, 1993 and November 30, 1993. The experimental group consisted of patients treated on Monday, Wednesday and Friday. The control group consisted of patients treated on Tuesday, Thursday and Saturday The pre-experimental survey utilized the following tools. The physiological adaptation was measured by a graphic rating scale for pain and activity of daily living. The psychological adaptation was measured by Zung's depression scale and Rosenberg's self-esteem scale : and the social adaptation was measured by Derogatis' psychosocial adjustment scale. The experimental group received muscle relaxation treatment for 15 minutes per day for the period of 2 weeks, the control group received no treatment and had quiet time. The post-experiment measurement was carried out similar to the pre-experiment survey, SPSS $PC^+$ is used to analyze the collected data. The reliabilities of the measurement tools were examined by Cronbach's ${\alpha}$ coefficients. The homogeneities between the experimental and control groups were tested by t-test and chi-square test, hypotheses were tested by t-test. This research found that the general characteristics between the groups were statistically homogenious. The physiological, psychological, and social adaptation between the groups in the pre-experimental survey were also statistically homogenious. The results of this research can be summarized as follows : 1. Concerning the Physiological adaptation, the experimental group showed a statistically lower pain score than the control group. Thus, muscle relaxation was effective to relieve the pain of rheumatoid arthritis patients (t=-2.95, p=.006). 2. Concerning the psychological adaptation, the experimental group showed a statistically lower depression score than the control group. Thus, muscle relaxation was effective to reduce the patient's depression(t=-4.00, p=.001). 3. Concerning social adaptation, the experimental group showed a statistically higher score for the health maintenance and disease control than the control groups. Thus, muscle relaxation was effective for the health maintenance and disease control (t=2.09, p=.004). This research showed that the muscle relaxation is a nursing intervention that can promote the physiological, psychological and social adaptation of the rheumatoid arthritis patients in terms of short-term and cognitive changes. However, more fundomental changes in behavior and long-term physiology could not be found through such a short-term relaxation treatment.

Physiological changes of the murine hybridoma cell line $S3H5/\gamma{2bA2}$ during adaptation to RPMI 1640 medium with 1%(v/v) fetal bovine serum were characterized in terms of cell growth, antibody production, morphology, and metabolic quotients. Cells adapted to 1% serum medium in T-flasks became sensitive to shear induced by mechanical agitation and required at least 5% serum in the medium or spent medium for cell growth in spinner flasks, while cells adapted to 10% serum medium in T-flasks could grow in 1% serum medium in spinner flasks. Consequently, long-term adaptation to low serum media may not give the expected growth enhancement. After adaptation to 1% serum medium, changes in cell morphology were observed. The cells in 10% serum medium were uniform and circular, while cells in 1% medium were irregularly shaped. The DNA contents, which were measured by flow cytometry, were almost constant among the cells in the range of 1% to 10%. Further, no significant changes in energy metabolism and specific monoclonal antibody production rate were observed among these cells.

The actual clothing conditions were surveyed to diagnose clothing condition of Korean female in the view point of the adaptation to the thermal environment according to seasonal changes. Then, clothing microclimate, physiological responses, and subjective sensation were investigated through wearing trials on human body in climatic chamber based on the results from the survey. Factors to evaluate validity of clothing condition were clothing weight, clothing microclimate, physiological response of human body, and subjective sensation. The results were as follows: 1. Clothing weight per body surface area of the season was $856g/m^{2}$, $439g/m^{2}$ in summer, $630g/m^{2}$ in fall, and $1184g/m^{2}$ in winter. Cold - resistance of Korean female in office was superior to Japanese, inferior to residents of rural areas of Korea, and similar to male in office. However, in heat - resistance, female in office was inferior to residents of rural areas of Korea. 2. In spring, fall, winter, clothing microclimate temperature was a little higher than that in summer. Therefore, it was not a desirable wearing condition even though the clothing microclimate was comfortable zone. 3. Mean skin temperature of female in office was including within the range of Winslow's comfortable zone, but the range of comfortable zone in mean skin temperature of female was more narrow than Winslow's. Thus, it has problem for female to adaptation to thermal environment.

In the present study, all of the treadmill exercise-trained SHR expressed clear adaptive changes such as reduced resting heart rate and blood pressures, LPOA, homocysteine Therefore, treadmill exercise was sufficient to induce physiological adaptation in the SHR. Endurance training is known to induce physiological cardiac hypertrophy, while hypertension induces patho logical cardiac hypertrophy that increases cardiomyocyte apoptosis. The pathological adaptation to pressure overload has also been associated with a further increase in the expression of several marker genes including cardiomyocyte ET-1 in the SHR, but not in the exercise-trained SHR. Additionally, there is an increase in the endothelial nitricoxide synthases (eNOS) protein expression of soleus, gastrocnemius, and extensor digitorum longus muscle in the exercise-trained SHR but not in the SHR in the present study. Thus, compared to pathological adaptation to pressure overload, physiological adaptation to exercise training is associated with distinct alterations in cardiac and molecular phenotypes. based on these results, exercise training improves hypertension by cardiovascular regulating genes and hemodynamic parameters.

To study the physiological adaptation (shift-up) of phytoplankton under the simulated upwelling conditions, nitrate uptake capacity of Dunaliella tertiolecta batch culture was measured in the laboratory using the stable isotope $^{15}N-KNO_3$. Contrary to the expected, there was no significant relationship between the maximum $V_{NO3}$ (nitrogen specific nitrate uptake rate) and the initial nitrate concentration. However, there was a strong relationship between the maximum $\rho_{NO3}$ (nitrate transport rate) and the initial nitrate concentration of $<25\;{\mu}M$, which was also influenced by the physiological status of the culture. The increase in $V_{NO3}$ was mainly due to the increase in PON (particulate organic nitrogen) concentration and partly due to the increase in $V_{NO3}$. When the phytoplankton population was severely shifted-down, the physiological adaptation of nitrate uptake was significantly inhibited at high initial nitrate concentrations. The timing of the maximum $V_{NO3}$ or $\rho_{NO3}$ was related to the initial nitrate concentration. At higher initial nitrate concentrations, maxima in $V_{NO3}$ and $\rho_{NO3}$ occurred 1 or 2 days later than at lower nitrate concentrations. This relationship was the opposite to the prediction from the shift-up model of Zimmerman et al. (1987), The shift-up process is apparently controlled by an internal time sequence and the initial nitrate concentration, but the magnitude of $V_{NO3}$ was affected little by changes in nitrate concentration.

The distribution of circumferential strain of arterial cross-section Is highest at intima and lowest at adventitia. However, the circumferential strain is theoretically severe at Intima because there is strain concentration. The theoretical degree of the intimal strain can not be explained in physiological condition even though artery is physiologically normal. Physiological adaptation may be undertaken to strain concentration. However, it is not clear, yet. Residual strain of artery is eagerly studied. There is experimental evidence that residual strain exists in artery. When ring of artery is longitudinally cut, it is opened. Assumption is made that intimal strain concentration is reduced with the considel'ation of residual strain. This study experimentally attempts to quantify the effect of residual strain on circumferential strain which is determined under the assumption of zero strain with zero pressure.

Purpose: To identify needs for pregnancy and postpartum adaptation of Chinese immigrant women and Vietnamese immigrant women in South Korea. Methods: A descriptive research design was employed. Data were collected from 244 Chinese immigrant women and Vietnamese immigrant women from 3 provinces, 20 health care centers, and multi-cultural family support centers. Data were analyzed with descriptive statistics, t-test and ANOVA. Results: An average score for needs perceived by Chinese immigrant women was significantly higher than that perceived by Vietnamese immigrant women. There were significantly differences in physical and emotional adaptation after childbirth, nutrition during pregnancy, cross cultural understanding and personal respect, and adaptation daily activity during pregnancy between the 2 groups. The highest score of needs in Chinese immigrant women was for nutrition during pregnancy and that in Vietnamese immigrant women was for baby rearing and family support. Conclusion: Based on needs of pregnancy and postpartum adaption, nursing intervention program in consideration of cultural characteristics of Chinese immigrant women and Vietnam immigrant women need to be developed for their pregnancy and postpartum health care.

Purpose: This study sought to develop the Breastfeeding Adaptation Scale-Short Form (BFAS-SF) for use at 4 weeks postpartum, to test its validity and reliability, and to examine its measurement invariance. The latent mean score of the BFAS-SF across multiple groups was also compared. Methods: This methodological research study was conducted to develop a short form of the BFAS and to test its psychometric properties and measurement invariance. Data were collected twice for measurement invariance testing. The sample included 431 and 272 breastfeeding mothers at 2 weeks and 4 weeks postpartum, respectively. Results: Confirmatory factor analysis supported six dimensions of the BFAS-SF at 4 weeks postpartum. Multi-group confirmatory factor analysis revealed evidence for invariance of the BFAS-SF according to employment status, parity, delivery mode, and the postpartum period. There were statistically significant latent mean differences. Mothers who were unemployed and who had a vaginal delivery showed significantly higher scores for breastfeeding confidence, sufficient breast milk, and baby's satisfaction with breastfeeding. Conclusion: The BFAS-SF is valid, reliable, and an appropriate instrument for assessing mothers' breastfeeding adaptation. It can be used to compare mean scores according to employment status and delivery mode.

[Purpose] Exercise is a fundamental way to maintain and improve health and physical fitness. Many human studies have demonstrated the beneficial effects of exercise on various biological parameters. However, studies investigating the effects of exercise in dogs are limited. This review summarized the current data from studies that examined the effects of different exercise conditions (treadmill vs. non-treadmill and acute vs. chronic) on physiological and hematological parameters in dogs. [Methods] Papers addressing the effects of exercise in dogs published from January 2000 to October 2020 were retrieved from the online databases of Scopus, Google Scholar, and PubMed and were selected and reviewed. [Results] The exercise conditions differentially affected physiological and hematological responses and adaptation in dogs. Therefore, the development and comprehensive evaluation of scientific exercise programs for dogs are necessary. [Conclusion] The dog would be a valuable exercise science animal model, and studies aiming at the optimal health, well-being, and quality of life of dogs need to be conducted.
