Objectives: The purpose of this study was to investigate the effect of the massage program stimulating the acupuncture points and meridians on the improvement of sleep quality. Methods: 16 subjects suffering from sleep disorders were recruited and the massage program was conducted 3 times a week for a month. VAS (Visual Analog Scale) and KPSQI (Korean Pittsburgh Sleep Quality Index) were collected through questionnaires, and salivary cortisol concentration test and HRV (Heart Rate Variability) were also used to evaluate the effect. The collected data were analyzed by independent statisticians. Results: VAS and KPSQI values decreased significantly after 4 weeks of massage chair application. There was no significant difference in salivary cortisol concentration and HRV test results. In the group with normal HRV test results and salivary cortisol concentration, the change of VAS and KPSQI values was not significant, while the group with abnormal range showed a statistically significant decrease. Conclusions: The massage chair program stimulating meridians according to Korean medicine theory was effective in improving sleep quality. Massage of acupoints and meridians through a massage chair is expected to be useful as an adjunctive therapy in addition to standard Korean medicine therapy.

현대인의 피로누적과 스트레스로 인한 근육 뭉침이나 어깨 결림과 같은 고통을 호소하는 사람들을 위해 힐이, 피로회복 개념으로 안마에 대한 욕구가 계속 증가하고 있다. 이를 위해 안마의자가 개발되고 있으나 한국인의 체형에 맞지 않아 가장 효율적인 안마를 제공하지 못하고 있다. 본 논문에서는 관련연구로 안마, 어셈블러, 안마강도, 한국인의 체형을 분석하고 효율성을 극대화하기 위한 기능을 분석하였다. 또한 한국인 체형에 맞는 동작제어기 및 알고리즘을 개발하였다.

2000년대 중반 마음과 정신의 치유를 뜻하는 힐링이 새로운 사회 문화로 급부상하고 이에 따른 헬스케어의 일부인 안마의자 시장은 꾸준히 성장세를 기록하며, 이에 부응하여 국내 안마의자 시장도 치열한 경쟁 상황에 이르게 되었다. 급속히 성장하고 있는 국내 안마의자 시장 경쟁력을 갖추기 위해서는 신기술 개발 및 경쟁력 제고를 위한 전략적 추진 방안이 필요하다. 따라서 본 연구에서는 안마의자 시장 동향 조사를 통한 외부한경 변화 및 경쟁사 현황 분석을 하였으며, 안마의자 기술 동향 조사를 통한 안마의자 현행 기술 분석 및 미래 기술 대안을 수립하고 각 기업 내부 현황 및 경쟁 분석을 통한 대응방안을 수립하였다. 또한 이를 토대로 4대 전략과제를 도출하여 향후 추진 전략 및 추진 과제를 제안하였다.

The customer of massage chair is expanding day by day from middle age to all ages. In 2018, the market size was 700 billion KRW, an increase of 30 times over 10 years. However, most related SMEs suffer from excessive competition by the market monopoly of some major companies. In this situation, in order for a related company to survive, it is necessary to steadily research and develop new products. Founded in 2009, company L produces massage chairs for health and relaxation of customers. L's products use a sound wave vibration module that is favorable for human body, unlike other products that use vibration motor type. However, frequent breakdowns of massage chair due to the vulnerability of plate (leaf) springs, which play an important role in sound wave vibration modules, made sap its competitiveness. In this paper, we propose a method to design desirable plate spring structure by sequentially experimenting with five different plate springs. The results of this study are expected to contribute to improve the quality of plate spring and the reliability of sound wave vibration module. In the future, it is necessary to find a way to use it in the development of foot massage or scalp management device as well as continuous research to find optimal plate spring structure through various analysis.

Objectives : The purpose of this study is to investigate the effect of acupoint and meridian muscle massage given by automatic massage chair. Methods : We recruited 30 patients with back pain who met inclusion criteria. Two weeks were given as a waiting period, and the massage intervention was applied 12 times for 4 weeks. The programmed automatic massage chair was used to provide effective stimulus on acupoints and meridians for 20 minutes. We used Visual analog scale(VAS) and Korean Oswestry Disability Index(KODI) to quantify pain and function. We also recorded patients' all of vital signs and abnormal reactions during the trial to asses to assess safety. Results : Two participants dropped out due to personal reasons and 28 participants completed the clinical trial. We found that the degree of back pain (VAS, KODI) decreased significantly after the trial. As a result, VAS score decreased from $6.44{\pm}0.85$(Visit 2) to $4.59{\pm}1.52$ (Visit 14)(p<0.001), and KODI score was also reduced from $14.79{\pm}5.13$(Visit 14) to $9.04{\pm}4.52$ (Visit 2) (p<0.001). Also, we did not find any adverse effects in this study. Conclusions : We found that the acupoint and meridian muscle massage can effectively decrease back pain. This proves that the massage program designed by Korean medicine can be a good option to patients with back pain. However, further study with controlled design is still needed to verify its effectiveness.

본 연구에서는 16명의 건강한 성인을 대상으로 뇌파를 이용하여 휴식모드인 대조군과 체어형 전동 안마기에서 수행된 2가지 모드(약, 강)에 따라 뇌파의 변화를 관찰하고 이를 통해 안마기가 스트레스 완화에 미치는 효과를 검증하고자 하였다. 모든 피검자에서 스트레스 정도를 설문으로 평가하는 시각적 상사척도(VAS: Visual Analog Scale)에서는 세 가지 모드에서 모두 유의한 차이를 보이며 감소하였으며 이중 안마모드 강에서 가장 큰 감소를 보였다. 뇌파 변화에서는 세 가지 모드에서 모두 서파인 delta파, theta파가 증가하였으며 이 중 안마모드 강에서 유의한 증가를 보여주었다. 반면 세 가지 모드에서 모두 alpha파는 감소하고 안마모드 약과 안마모드 강에서 유의한 차이를 보였다. beta파의 경우 대조군을 제외한 안마모드 약과 안마모드 강에서 감소하였고 이중 안마모드 강에서 통계적으로 유의한 차이를 보여주었다.

Purpose: This study was object to the effects of a resistance exercise combined with relaxation therapy on blood pressure, frequency of exercise and physical fitness in elderly women. Methods: Seventy three elderly women participated in an exercise program for 12 months. The exercise program consisted of stretching, massage and resistance training using thera-bands twice a week and 50 minutes in every sessions each week. Repeated measures ANOVA were performed using SAS. Results: After the exercise program there was a significant difference in systolic blood pressure, frequency of exercise, body fat, sitting to standing, walking 2 minutes, sitting on a chair and reaching, and standing on one leg with eyes opened. After 6 months, there was a significant decrease in systolic blood pressure and significant increase in frequency of exercise, body fat, sitting to standing and standing on one leg with eyes opened. In 12 months, there was a significant increase in body fat, 2 minutes walking, and sitting in a chair and reaching. Conclusion: Resistance exercise combined with muscle relaxation therapy would have a positive effect on elderly women. We found that it was helpful for the elderly women in terms of physical fitness.
