Purpose: This study was done to examine how laughter therapy impacts serotonin levels, QOL and depression in middle-aged women and to perform a path analysis for verification of the effects. Methods: A quasi-experimental study employing a nonequivalent control group and pre-post design was conducted. Participants were 64 middle-aged women (control=14 and experimental=50 in 3 groups according to level of depression). The intervention was conducted five times a week for a period of 2 weeks and the data analysis was conducted using repeated measures ANOVA, ANCOVA and LISREL. Results: Results showed that pre serotonin and QOL in women with severe depression were the lowest. Serotonin in the experimental groups increased after the 10th intervention (p=.006) and the rise was the highest in the group with severe depression (p=.001). Depression in all groups decreased after the 5th intervention (p=.022) and the biggest decline was observed in group with severe depression (p=.007). QOL of the moderate and severe groups increased after the 10th intervention (p=.049), and the increase rate was highest in group with severe depression (p<.006). Path analysis revealed that laughter therapy did not directly affect depression, but its effect was indirectly meditated through serotonin variation (p<.001). Conclusion: Results indicate that serotonin activation through laughter therapy can help middle-aged women by lessening depression and providing important grounds for depression control.

Purpose: The purpose of this study was to apply laughter therapy to clinical practice and investigate its effects on patients' anxiety and depression in order to increase the quality of nursing for patients with inflammatory bowel disease (IBD). Methods: The study was conducted based on the non-equivalent control group pretestposttest design. The participants include 20 patients with IBD in the control group and 17 in the experiment group. Data was collected from July 10th, 2011 to January 22nd, 2012. Laughter therapy was administered once a day for five consecutive days. Results: The anxiety score was significantly different between the two groups and indicates that laughter therapy is effective for reducing anxiety among patients with IBD. Futhermore, there were differences in the depression scores of the experiment group between the pre-test and post-test, but no significant differences were found between the two groups. Conclusion: The results show that laughter therapy was effective in reducing anxiety among patients with IBD but did not decrease depression directly. Considering that the experiment group had a bigger reduction rate in depression scores than the control group. However, it is expected that laughter therapy will serve as an emotional nursing intervention for patients with IBD.

Purpose: The purpose of this study was to examine the effect of laughter therapy on depression, anxiety, fatigue, and quality of sleep in gastrointestinal cancer survivors. Methods: This study was a randomized controlled trial. We compared the effect of laughter therapy with usual care only in post chemotherapy gastrointestinal patients. Outcomes included changes in depression and anxiety (according to the Hospital Anxiety and Depression Scale), fatigue (according to the Fatigue Severity Scale), and quality of sleep (according to the Verran & Synder-Halpern Sleep Scale). Data was collected July 2015 through January 2016. Seventy nine participants who agreed to participate in this study were randomized to either the experimental group (n= 40) or the control group (n= 39). Therapy included eight sessions (60 minutes each, once weekly). Data were analyzed using the Windows SPSS 22.0 program. Results: Laughter therapy was effective in reducing fatigue (p= .019) and increasing satisfaction of sleep (p= .030). There were no differences between the groups after therapy for depression (p= .129) and anxiety (p= .200). Conclusion: Results of this study indicate that laughter therapy may be an effective nursing intervention for improving the health status of gastrointestinal cancer survivors after chemotherapy.

This study examined the effects of laughter therapy in the elderly with degenerative arthritis who had joint pain, joint dysfunction, and depression. Through a single-blind, randomized assignment, an experimental group of 26 subjects and a control group of 26 subjects were recruited among the elderly with degenerative knee arthritis, who were over 65 years of age. From January 8 to March 11 of 2019, a total of 16 laughter therapies were administered two times a week, 60 minutes per session, in eight weeks. The pain threshold (p=.012) and joint function status (p<.001), which represents the pain, joint stiffness, and physical function, and depression (p<.001), in the experimental group improved after the eight weeks laughter therapy compared to the control group. Laughter therapy is a therapeutic intervention that can be delivered through physical or intellectual activities. This therapy is a non-invasive procedure and has the advantage that nurses can practice easily with a little training. It can be used as an intervention within community and clinical settings to relieve pain and improve depression in the elderly with arthritis.

Purpose: This study was aimed at constructing and examining the effects of a laughter therapy program for elderly patients in long-term care hospitals. Methods: A prospective, two-group quasi-experimental design was used and 50 patients (25 experimental and 25 control group patients) from two long-term care hospitals in Gyeonggido province, South Korea, were study participants. The experimental group received 24 laughter therapy sessions twice a week for 12 weeks, and the control group received laughter therapy after data collection. Data were collected between May 26 and August 17, 2014. Results: The level of cognitive function for the experimental group increased(t=3.27, p=.002). The level of forced vital capacity (t=2.78, p=.008) and forced expiratory volume in 1 second (t=4.94, p<.001) increased among members of the experimental group. Conclusion: These results indicated that the laughter program was effective in improving cognitive and pulmonary functions among older patients who were receiving long-term care in hospitals. This program could be used for community-based elderly patients.

아름다움이라는 것은 완전히 객관적이기도 하지만 극히 주관적인 표현의 결과일 수 있다. 심미치의학은 얼굴에서 표현되는 이러한 주관적인 면과 객관적인 면을 조화시킬 수 있는 학문이기에 21세기에도 여전히 치과 치료에 있어서 중요한 화두 중의 하나임에 틀림이 없다. 과거 심미적인 치료로 행하였던 많은 치료 술식들(open faced crown, resin faced crown,3/4 crown,7/8crown등)이 치과 치료 술식의 발달과 함께 재료와 치아 보철물 제작술 등의 발달로 인해 점차 사라지거나 변화하고 있는 것이 사실이다. 지금 소개하는 증례들은 현재 치과계에서 심미적인 치료 술식으로 인정하고 있기에 이러한 치료 술식에 대한 이해가 필요할 것이다. 우리 임상가들의 최종목표는 환자들에게 자연스러운 얼굴과 웃음을 회복시켜주는 것이다. 각 증례에 대한 한계에 대해 미리 알 수 있는 방법을 모색해 보고, 예측 가능한 치료를 시행하기위한 과정들을 살펴보고자 한다.

언제 더웠냐 싶게 꽤나 썰렁한 바람이 부는 날이다. 추수를 하고 있는 농부의 모습이 차창을 스치고 지나간다. 수건을 쓴 어느 아주머니가 허리를 펴고 하늘을 한번 쳐다본다. 무슨 재미있는 얘기를 주고받았을까. 커다란 웃음소리가 크게 들렸다가 서서히 사라져간다. 기자는 건강검진차를 찾아, 자궁암검사를 받았다가 병을 조기발견하고 두 달에 걸친 치료 끝에 건강을 되찾아 행복한 생활을 하고 있는 정부영씨(경기도 수원시 세곡2동 537-19)를 만나러 갔다. 자신이 당한 일을, 슬퍼하기 보다는 좋은 경험이라고 얘기하는 그녀를 만나면서, 기자는 많은 것을 생각하고 배울 수 있었다.

Purpose: The purpose of this study is to examine the influence of laughter therapy programs on middle school students' happiness, self-esteem and school life adaptation. Methods: In total, 60 students (Experimental group= 30. Control group=30) were recruited to answer a self-administered questionnaire. The questionnaire was composed of questions about general characteristics, happiness, self-esteem and school life adaptation. The experimental group participated in a 45-minute laughter therapy program once a week for eight weeks, while the control group did not. Results: The scores of happiness(t=-4.68, p<.001), self-esteem(t=-3.38, p=.001), and school life adaptation(t=-3.76, p<.001) in the experimental group got significantly higher than the control group. Conclusion: Based on this study results, laughter therapy programs should be applied to improve happiness, self-esteem, and school life adaptation of middle school students.
