본 논문은 실시간 카메라 영상으로부터 얼굴을 검출하고 얼굴 표정을 인식하여 웃음 치료훈련을 할 수 있는 시스템을 제안한다. 제안된 시스템은 카메라 영상으로부터 Haar-like 특징을 이용하여 얼굴 후보 영역을 검출한 다음, SVM분류기를 이용하여 얼굴 후보 영역이 얼굴 영상인지 아닌지를 검증한다. 그 다음에는 검출된 얼굴 영상에 대해, 조명의 영향을 최소화하기 위한 방법으로 히스토그램 매칭을 이용한 조명 정규화를 수행한다. 표정 인식 단계에서는 PCA를 사용하여 얼굴 특징 벡터를 획득한 후 다층퍼셉트론 인공신경망을 이용해 실시간으로 웃음표정을 인식하였다. 본 논문에서 개발된 시스템은 실시간으로 사용자의 웃음 표정을 인식하여 웃음 양을 화면에 표시해 줌으로써 사용자 스스로 웃음 훈련을 할 수 있게 해 준다. 실험 결과에 따르면, 본 논문에서 제안한 방법은 SVM 분류기를 통한 얼굴 후보 영역 검증과 히스토그램 매칭을 이용한 조명정규화를 이용하여 웃음 표정 인식률을 향상시켰다.

Purse: The purpose of this study was to examine the effect of a laughter therapy on mental health promoting like depression, laughing index of elderly. Methods: The study was conducted based on the non-equivalent control group pretest-posttest design. The participations included 12 older adults in the control group and 11 in the experiment group. Data was collected from October 1 to November 22, 2013. Experimental group participated in laughter therapy six times, once a week for 60 minutes of each session. Questionnaires were used to measure pretest and posttest levels of depression and laughing index. Results: At the end of six-week intervention, depression score (z=-2.95 p=.003) and laughter index score (z=-2.81 p=.005) was significantly decreased in the experimental group compared to the control group. Futhermore, there was a significant difference in the depression scores of the experiment group at the posttest, but no signigicant difference was found between the two groups. Conclusion: The study results suggest that the laughter therapy is an effective intervention to reduce the depression but helpful to enhance the laughing index. Therefore, it is expected that laughter therapy will serve as an emotional nursing intervention for elderly patients with depression.

병적 웃음과 울음(Pathological laughing and crying, PLC)은 감정과 관계없이 갑작스럽게 표출되는 웃음이나 울음이 특징이며 신경계 질환과 관련 있다. 이는 환자의 대인관계 및 일상생활에 상당한 곤란을 가져오지만 약물치료에 비교적 반응이 좋으므로 적절한 진단이 중요하다. PLC는 전전두엽과 변연주변 네트워크(paralimbic network), 소뇌 및 교뇌 기저의 조절이상으로 발생한다. 이들의 조절에는 여러 신경전달물질이 관여하며 특히 세로토닌성 기능의 이상이 관련있다. 주된 치료는 약물치료이며 선택적 세로토닌 재흡수 억제제를 비롯한 항우울제에 좋은 효과를 보인다. 그 외 도파민계 약물, 비경쟁적 NMDA 수용체 길항제도 일부 효과가 있다. PLC의 진단과 평가에는 몇 가지 척도들이 사용되고 있으나 그 특징적 임상양상을 파악하는 것이 가장 중요하다. 따라서 이러한 PLC의 임상양상과 병태생리를 이해하고 적절한 치료법을 살펴봄으로써 임상에서의 관심을 높이고자 한다.

Purpose: This study was done to identify the effects of Laughter therapy on recovery status from facial paralysis, pain, and stress in Bell's palsy patients. Methods: This research was a nonequivalent control group non-synchronized pre-posttest quasi-experimental research design. Data were collected from August 8, to October 15, 2013 at D university Oriental Medical Center in B city. Participants were 60 patients with Bell's palsy who were assigned to one of two groups: an experimental group of 30 patients and a control group of 30 patients. t-test, $x^2-test$, Fisher's exact test and Welth-Aspin test were used to test the homogeneity between the two groups and t-test, Welth-Aspin test and ANCOVA were used to test the research hypotheses. SPSS program was used for statistical analysis. Results: There were significant increases in recovery status from facial paralysis and decreases in stress after Laughter therapy in the experimental group. Conclusion: The results indicate that Laughter therapy is effective in facilitating recovery status from facial paralysis and decreasing stress. Therefore, Laughter therapy can be used as an effective nursing intervention for patients with facial paralysis and to relieve stress in these patients.

Purpose: This study examines the difference of optimism, self-esteem and depression to verify an effect of laughter therapy program for menopausal women. Methods: A quasi-experimental nonequivalent control group pre / post-test design was used. The participants (n=57) were 28 in the experimental group and 29 in the control group. The data were collected in December of 2011. The experimental group participated in laughter therapy for 30 min per session, five times a week for the period of 2 weeks. The questionnaires were used to measure pre / post-test optimism, self-esteem, and depression of menopausal women. Results: The results showed that laughter therapy was effective in increasing optimism (p= .020) and self-esteem (p<.001). And the depression of menopausal women decreased (p= .003). Conclusion: The result of the study indicates that laughter therapy for menopausal women may be an effective nursing intervention to improve optimism, self-esteem and depression of menopausal women.

Purpose: The purpose of this study was to examine the effect of laughter therapy on arthralgia, ankylosis, depression and sleep of elderly housebound women suffering from osteoarthritis. Methods: The study used a nonequivalent control group pretest-posttest design. The participants were 48 elderly women: 23 in the experimental group and 25 in the control group. The experimental group received laughter therapy twice a week for 4 weeks. The results were analyzed by using $X^2$-test, ANCOVA, and t-test with the SPSS/WIN 21.0 program. Results: The results showed that laughter therapy had a significant statistical effective in reducing arthralgia, ankylosis, and depression and improving the quality of sleep as evidenced by the differences between the two groups. Conclusion: The results of this study indicated that laughter therapy is an effective nursing intervention reducing arthralgia, ankylosis, and depression and improving the quality of sleep in these women. Therefore, it is necessary to develop laughter therapy as an independent nursing intervention for elderly women with osteoarthritis who are housebound.

Purpose: The purpose of this study was to examine the effects of the laughter therapy program on perceived stress and psycho-neuro-endocrine-immune responses in obese women. Methods: A nonequivalent control group with a pretest-posttest design was used. The participants (n=60), whose age ranged from 30 to 50 years (pre-menopausal and body mass index of over $25kg/m^2$), were assigned to the experimental group (n=24) or control group (n=26). The experimental group was provided with the laughter therapy program (12 sessions) for 6 weeks. Results: There were significant differences in perceived stress, psychological stress response, fasting blood sugar, interleukin-6, and tumor necrosis factor alpha between the two groups after the program. However, there were no significant differences in normalized low frequency (norm LF), normalized high frequency (norm HF), LF/HF ratio, and cortisol between the two groups after the program. Conclusion: It was found that the laughter therapy program had positive effects on some variables in terms of perceived stress and psycho-neuro-endocrine-immuno responses. It is suggested that the laughter therapy in this study can provide the direction for developing a program for obese women.
