  • A comparison was made between the effect of subjective stress and that of objective stress on immune function in male medical college students. Interaction between perceived stress, psychopathology and natural killer-cell(NK) activity was assessed during an exam period, non-exam period, and vacation. No significant difference was found in NK activity among these three periods, but scores of perceived stress related to unusual happenings during an exam period and related to interpersonal relationship during vacation were found to have significantly positive correlation with NK activity, respectively. In psychopathology, only scores of anxiety during an exam period had significantly positive correlation with NK activity. These results suggest that immune function is more likely to be affected by subjective stress than objective stress and that subjective stress such as some perceived stress and subclinical level of anxiety may positively affect immune function.

  • Purpose: The purpose of this study was to evaluate the effects of a combination program of meridian massage and foot reflexology on stress and natural killer (NK) cell activity in adults. Methods: This study is a quasi-experimental research usingone-group-pretest-posttest design. The subjects of the study were 42 adults in T city. Stress level was assessed with systolic blood pressure, diastolic blood pressure, pulse rate, and serum cortisol level. The data were analyzed by SPSS/WIN 17.0 program with descriptive statistics and Wilcoxon signed-rank test. The period of this study was from January 4 to July 11 of 2008. The program was performed three days per week, two hours per session. Results: The degrees of perceived stress were significantly different while objective stress levels were partially different between pre-and post-program. The NK cell activity did not show a significant difference between before and after the program. Conclusion: This study suggests that combination of meridian massage and foot reflexology may be an optional nursing intervention to reduce subjective and objective stress in adults.

  • One year has passed since the pandemic of COVID-19, which occurred in Wuhan, China, in November 2019 began. Worldwide, as of January 2021, more than 95 million people have been infected, and the death toll is higher than 2 million. In Korea, there are 74,262 infected and 1,328 dead, and government policies such as social distancing to prevent infection are being implemented. Accordingly, many inconveniences occurred in the physical activity environment, such as the closure of various sports facilities. It was necessary to consider physical activities to maintain healthy life while cooperating with the national policy while preventing infection. This study investigated the benefits of physical activity to reduce the risk of trichomoniasis and diabetes, improve bone mineral density, prolong healthy lifespan, maintain activity performance with aging, and improve psychological anxiety and depression. In addition, the physiological changes that may occur in the situation of stopping exercise due to social distancing to prevent COVID-19 infection were reviewed. In addition, moderate-intensity exercise that helps strengthen immune function by activating natural killer cells, neutrophils, and antibody responses was investigated. In addition, it reduces the level and function of blood B-cells, T-cells, and natural killer cells for several hours, decreases phagocytosis of neutrophils in the nasal cavity, increases inflammatory cytokines, decreases immune function, and increases infection. High-intensity exercise was considered. Therefore, in the age of COVID-19, long-term high-intensity exercise such as marathon, which causes impaired immune function, should be refrained from. And you should do moderate-intensity regular aerobic exercise such as fast walking to help prevent infection. It is also recommended to participate in resistance exercises to prevent loss of muscle mass.
