현대성,정다이,김창수,류혜윤,장세진 연세대학교의과대학 2020 Yonsei medical journal Vol.61 No.2
Purpose: To investigate whether emotional labor is associated with suicidal ideation in Korean firefighters. Materials and Methods: Data were obtained from the Firefighter Research: Enhancement of Safety & Health (FRESH) Study,which was designed to investigate the effects of job characteristics on mental and physical health among Korean firefighters. A totalof 18101 firefighters were chosen from a nationwide sample. The Korean Emotional Labor Scale (K-ELS) was used to evaluate exposureto emotional labor, which consisted of five sub-factors: emotional demand and regulation, overload and conflict in customerservice, emotional disharmony and hurt, organizational surveillance and monitoring, and lack of a supportive and protectivesystem in the organization. Results: Firefighters who were in the risk group were more likely to experience suicidal ideation than those in the normal group foreach of the five sub-scales of emotional labor. The estimated mean values for suicidal ideation in the risk group were significantlyhigher than those in the normal group: 1.667 (95% CI: 1.344–2.069) for emotional demand and regulation, 1.590 (95% CI: 1.243–2.033) for overload and conflict in customer service, 2.409 (95% CI: 1.954–2.969) for emotional disharmony and hurt, 2.214 (95% CI:1.832–2.676) for organizational surveillance and monitoring, and 1.665 (95% CI: 1.387–1.999) for lack of a supportive and protectivesystem in the organization. Conclusion: These results suggest that experience and exposure to chronic and excessive emotional labor might play a crucialrole in the development of suicidal ideation among firefighters.

목적 : Pilocarpine과 pentylentetrazol에 의하여 야기되는 경련유발이 뇌의 nirtric oxide synthase의 활성도에 미치는 영향을 관찰하였다. 대상 및 방법 : 생쥐에 pilocarpine(250㎎/㎏)과 pentylentetrazol(70㎎/㎏)을 복강내 투여하여 경련을 유발시킨 뒤 시간 경과에 따른 해마, 대뇌피질, 소뇌에서의 NOS 활성도를 측정하였다. 결과 : Pilocarpine과 pentylentetrazol에 의한 경련 발작 시기와 해무 부위에서의 NOS 활성도가 증가는 거의 일치하였고 대뇌피질에서 NOS 활성도의 증가는 해마 부위에서의 증가보다 다소 시간이 지연되어 나타났다. 그리고 소뇌의 NOS 활성도 증가는 약물 투여에 의한 경련이 완전히 사라진 뒤인 1일 뒤에 NOS 활성도가 증가하는 양상을 보였다. 결론 : 경련 유발 약물에 의한 뇌의 NOS 활성도의 증가 시간은 뇌조직에 따라 현저한 차이가 있는 것으로 보여진다. The influence of pilocarpine(250 ㎎/㎏) and pentylenetetrazol(70 ㎎/㎏) on nitric oxide synthase activity was observed in the cerebral cortex, the hippocampus and the cerebellum of mice. In the hippocampus, the increase in NOS activity was prominent before and during the behavioral seizure episodes and in the cerebral cortex, NOS activity increased 3 hours following pilocarpine administration. In one day following pilocarpine treatment, NOS activity increased in the hippocampus, the cerebral cortex and the cerebellum. In the hippocampus, the increase in NOS activity was appeared during the behavioral seizure episodes and in the cerebral cortex, NOS activity increased 3 hours following pentylenetetrazol administration. In one day after pentylenetetraol treatment, NOS activity increased in the hippocampus, the cerebral cortex and cerebellum and the NOS activity remained high until 3 days after pentylenetetraol treatment in the hippocampus and cerebral cortex. These results show that NOS activity in the brain treated with pilocarpine and pentylentertrazol is different according to the site of the brain.

Objectives: Fatigue is a common and distressing symptom that is a concern for cancer patients. It has a decisive effect on quality of life. The purpose of this study was to examine the feasibility of clinical trial to evaluate of efficacy and safety of acupuncture on cancer related fatigue of lung cancer patients. Methods: Total lung cancer 9 patients complained of fatigue were treated by acupuncture twice a week for four weeks(8 times in total). Evaluation of the severity of fatigue was measured by FSS(Fatigue Severity Score). In visit 1, 10, we checked FSS. For check safety of acupuncture treatment, we did blood test. Results: After 4 weeks of acupuncture treatment, the FSS was significantly decreased from 4.92±1.06 to 3.74±1.37(p=0.008). And the level of hemoglobin was significantly increased from 10.87 g/dl to 12.01 g/dl(p=0.014). No other lab measures indicated any significant differences between before and after acupuncture treatment. Conclusions: This study suggests that acupuncture treatment will be beneficial for lung cancer patients to improve the fatigue severity. And acupuncture treatment is safe method for lung cancer patients. A large-scale study to confirm efficacy and safety of acupuncture is needed.
