Purpose: The purpose of this study was to determine the effects of music therapy on postpartum stress and maternal attachment of puerperal women. Methods: The participants were puerperal women who agreed to participate in this study and through a convenience sampling, 84 puerperal women were recruited (40 in the experimental group, 44 in the control group). After measuring postpartum stress and maternal attachment, music therapy was provided to the experimental group over 60min, three times a week, and for 2 weeks. Then, postpartum stress and maternal attachment for the experimental and control group were measured again before discharge. The data were analyzed using the SPSS/WIN 14.0 program. Results: The first hypothesis that "the degree of postpartum stress for the experimental group who participated in music therapy would be lower than that of the control group" was accepted. The second hypothesis that "the degree of maternal attachment the experimental group who participated in music therapy would be higher than that of the control group" was accepted. Conclusion: These findings indicate that music therapy has positive influences on decreasing postpartum stress and increasing maternal attachment of puerperal women.

Objective: This study is based on a parallax design before and after a non-equivalent control group to examine the effects of laughter therapy on the anxiety, depression, and stress in patients with cancer admitted to a nursing hospital. Design: A randomized controlled trial. Methods: Data collection was conducted on 34 patients who agreed to participate in the study among patients admitted to E Cancer Hospital from September to November 2018. Laughter treatment interventions were performed three times a week for 50 minutes each and a total of eight times. In this study, a tool developed by Spielberger was used to measure state anxiety, a tool developed by Beck was used to measure depression, and the Perceived Stress Scaled eveloped by Cohen was used to measure stress. Results: Anxiety was significantly lower in the experimental group than in the control group (F=10.74, p=0.003). Depression was lower in both the experimental group and the control group that did not participate in the laughter therapy intervention and was not significant (F=0.58, p=0.451). Stress was significantly lower in the experimental group than in the control group (F=4.36, p=0.045). Conclusions: The results of this study suggest that laughter therapy has a positive effect on reducing anxiety and stress in patients with cancer admitted to nursing hospitals.

수분 공급을 제한하여 수분 부족 스트레스를 처리한 상추식물에서 산화적 스트레스와 관련된 monodehydroascorbate reductase (MDHAR)의 활성도, 엽록소 함량, 과산화수소의 함량 등과의 상관관계를 조사한 결과, 생육배지의 수분의 함량이 감소함에 따라 식물체내 과산화수소의 생성량이 증가($R^2$=0.8851)하였으며, 수용성단백질 함량은 점차 감소($R^2$=0.9826)하는 경향을 나타내었다. 총 엽록소함량은 수분 부족 스트레스를 처리한 공시작물에서의 함량이 정상 생육시 보다 그 함량이 대체적으로 낮은 경향을 보였으며, 엽록소 a와 엽록소 b함량 변화도 총 엽록소의 함량변화와 비슷한 경향을 보였다. 그러나 총 엽록소에 대한 카로티노이드의 비율은 수분 부족 스트레스를 처리한 식물에서 정상생육 시 보다 더 높은 경향을 보였다. 수분 부족 스트레스가 진행됨에 따라 아스코브산의 함량은 정상 생육 시 보다 더 높은 경향을 보였으나 환원형인 디하이드로아스코브산의 함량은 수분 부족 스트레스를 처리한 초기에 정상생육 시 보다 더 낮은 경향을 보였다. MDHAR의 활성도는 사이토졸(cytosolic) 분획과 엽록체(chloroplastic) 분획에서 공히 크게 증가하였으며 MDHAR의 mRNA 전사 정도도 수분 부족 스트레스가 진행됨에 따라 크게 증가하였다. 수분함량이 감소함에 따라 MDHAR의 활성도가 크게 증가하였으며, 또한 과산화수소의 함량이 증가함에 따라서도 MDHAR의 활성도가 크게 증가($R^2$=0.9937과 0.8645)되어 수분 부족 스트레스로 나타나는 요인들과 MDHAR 사이에 밀접한 관련이 있음을 확인할 수 있었다.

Objectives: This study was designed to examine the effect of Hominis Placenta Pharmacopuncture on the change in behavior, sleep-related hormones, inflammatory cytokines, anti-oxidants, weight, blood, and serum on rats given chronic physical stress. Methods: Wistar rats older than age 10 weeks were used in this experiment. They were divided into six groups. The normal group was not given stress. The control group was given only chronic physical stress and no treatment. The positive control group was given chronic physical stress and treated with zolpidem. Three Hominis Placenta Pharmacopuncture (HPP) groups were given chronic physical stress, then treated with different concentrations of HPP; HPP-0.5× (0.5 times diluted), HPP-1× (undiluted) and HPP-2× (2 times condensed). The changes of values of Nestlet Shredding results, weight, Melatonin, Gamma-aminobutylic Acid (GABA), Tumor Necrosis Factor Alpha (TNF-α), Interleukin-6 (IL-6), Superoxide dismutase (SOD), glutathione peroxidase (GPx), AST, ALT, BUN, Creatinine, and leukocytes were observed during the experiment. Results: The changes in chronic physical stress of the rat model were as follow. The Nestlet Shredding result increased in the control group compared to the normal group (p<0.05), and decreased in the HPP-1× and HPP-2× compared to the control group (p<0.05). The amount of weight gain showed increasing tendency in the HPP-2× compared to the control group since the second week. The GABA increased (p<0.05) and Melatonin also showed certain increasing tendency in the HPP-1× and HPP-2× compared to the control group. The TNF-α and IL-6 increased in the control group compared to the normal group (p<0.01), and decreased in all the HPPs compared to the control group (p<0.05). The SOD level decreased in the control group compared to the normal group (p<0.01), and increased in all the HPPs compared to the control group (p<0.05). GPx, AST, ALT, Bun, Creatinine and leukocytes showed no noticeable difference among all groups. Conclusions: Hominis Placenta Pharmacopuncture was effective in increasing weight, GABA, Melatonin, SOD, and decreasing Nestlet Shredding and inflammatory cytokines, suggesting that it consequently facilitates in relieving physical stress.

In this paper, an experimental study is performed to adjust position of compliance center of Elastomer Shear Pad Remote Center Compliance (ESP RCC) device, which is used on precise peg in hole process. In the study, variation of the lateral/axial stiffness of the ESP is proposed as a control parameter to adjust the position of compliance center of the ESP RCC. The variation of the stiffness of the ESP is achieved by controlling the shear stress of the ESP. To control the shear stress of the ESP, position of top side of the ESP is changed while remaining bottom side of the ESP is fixed on the RCC plate. To evaluate effect of the proposed idea, stiffness variations of the ESP on various shear stresses are measured, and variation of the compliance center is measured with the ESP RCC that can control the position of compliance center by using the shear stress. The measured data shows unique characteristics that have not been shown in other types of ESP VRCCs.

This study was to identify the effects of home visit intervention program for Holistic Healthcare of multi-culture Couples. It used a non-equivalent control group pretest-posttest design quasi-experimental research. The subjects of this study consist of 20 couples for experimental and control groups. Multi-cultural couples comprised of foreign women married to Korean men in farm and fishery areas. The research tools were used stress index by SA-3000P (Medicare co. Ltd. KOREA), Center for Epidemiologic Studies-Depression Scale (CES-D), and World Health Organization Quality of Life (WHOQOL-Bref). The experimental group of the wives had lower stress index than the control group, the experimental group of the husband showed lower stress index than the control group, (t=-3.14, p=.002). The wife (t=-3.75, p=.001) and husband (t=-4.20, p=.001) of the experimental group showed lower depression scores than the control group. Both the wife (t=3.86, p=.001) and husband (t=5.28, p=.001) showed higher scores for quality of life compared to the control group. It was found that this holistic healthcare home visit program is an effective program to make improvements on stress, depression and quality of life for multi-cultural couples. Therefore, as the intervention program developed in this study is home visits for the holistic health of multi-cultural couples, and it is judged that it can be implemented at the local social health centers or healthcare centers.
