본 연구는 근육의 경도와 탄성도를 측정하여 교근 피로에 대한 물리치료의 효과를 정량적으로 평가하고자 하였으며, 측두하악장애 치료에 가장 흔히 사용되는 물리치료이면서 작용기전은 서로 다른 세 가지 치료법인 전기침자극치료(EAST), 극초단파(Microwave diathermy), 저수준레이저치료(LLLT)의 효과를 비교하였다. 실험을 위하여 건강한 20대 지원자 10명을 선정하여, 교근의 전부와 하부의 근육 경도와 탄성도를 촉각센서로 측정하였다. 실험적으로 교근 피로를 유발하기 위해 피검자가 VAS (0 to 10) 5 이상의 통증을 느낄 때까지 껌을 씹게 하여 근육 변화를 조사하였으며 치료 없이 15분간의 휴식을 준 다음 다시 검사하여 물리치료 후의 효과 비교를 위한 대조군으로 사용하였다. 하루 간격으로 사흘에 걸쳐 동일한 시간 동안 껌을 씹게 한 다음, 물리치료 한 가지씩을 매일 시행하였으며 3가지 물리치료법의 적용 순서는 무작위로 하였다. 껌 저작 전, 직후, 15분 후, 각각의 물리치료 시행 후에 근육 경도와 탄성도 측정과 함께 피검자들이 느끼는 근육의 피로도를 VAS로 평가 하도록 조사하였다. 실험 결과, 저작측에서만 껌 저작 직후와 15분 후에 근육경도의 증가와 탄성도의 감소가 관찰되었으며 (p<0.05) 비저작측에서는 유의한 차이가 없었으나 VAS는 저작측과 비저작측 모두에서 증가하였다(p<0.05). 껌 저작으로 인해 변화되었던 근육경도와 탄성도는 전기침자극치료나 극초단파 치료 후에 효과적으로 회복되고 VAS가 감소했으나(p<0.05) 저수준레이저 치료 후에는 유의한 변화를 보여주지 않았다. 이상의 결과로 보아, 편측 저작은 저작측 근육의 경도를 증가시키고 탄성도는 감소시키는 반면, 비저작측에서는 변화가 없는 것을 알 수 있다. 또한 전기침자극치료와 극초단파치료는 모두 근육의 경도를 감소시키고 탄성도를 증가시켜 근육의 피로를 감소시키는데 효과적인 치료법인데 반해 저수준레이저치료의 효과는 미약한 것으로 판단된다.

In Korea, there are many kinds of functional foods to manage diabetes, however, they have not been evaluated or investigated systematically. The purpose of this study was to investigate the status of recognition and intake of functional foods among diabetic patients. The study subjects were 307 patients(male 135, female 172), who diagnosed with type 2 diabetes at Seoul National University of Bundang Hospital. Questionnaire survey was done from July to October, 2004 for the characteristics of patients and factors related to the use of functional foods. The mean age of the subjects was 64$\pm$10.2 years, and the mean duration of disease was 9.5$\pm$8.90 years. Approximately 49.8% of the subjects had experience to use functional foods at least once in past. Total number of functional foods used were 56 types. Red ginseng was used most frequently(27.9%), then followed by Silkworm powder(13.6%), Vitamin supplements(10.4%), Mulberry tree(7.1%), Cordyceps sinensis(6.8%) and Ginseng(4.2%). Functional foods were introduced by their friends.relatives(38.4%), family(29.1%), internet(13.9%), and the mass media(10.6%). Among respondents, 94.7% took functional foods with conventional diet therapies(diet, exercise and medication). The purpose of functional food use was to control blood glucose level(49.0%), to relieve fatigue and improve stamina(19.9%), to treat and prevent a disease(17.2%) and to help blood circulation(7.9%). Upon the question of further recommendation of functional foods to others, 74.8% of the subjects answered negative response. However, 12.6% of the subjects showed the further intention of using new product. Therefore, to guide the appropriate use of functional foods for diabetic patients, diabetic educator should provide the knowledge of the efficacy of functional foods and the desirable guidelines.

BACKGROUND/OBJECTIVES: Although some juices affect subjective sleep quality, there is a lack of information on the effect of a specific juice on objective sleep quality and heart rate variability (HRV) during sleep; thus the present study investigated whether a blended juice made from natural extracts influenced sleep quality and HRV during sleep in adults with disturbed sleep. SUBJECTS/METHODS: A randomized, crossover study was conducted on twenty-five adults (15/10, female/male) complaining of difficulty initiating or maintaining nighttime sleep (Pittsburgh sleep quality index [PSQI] ≥ 5). During feeding sessions (FS), subjects received sleep-inducing juice made of natural ingredients (250 mL/trial) twice a day for 8 weeks or non-FS (N-FS) for 8 weeks while maintaining normal activities. Sleep quality and parameters were recorded via wearable actigraph for 7 consecutive days, and PSQI scores were assessed before and after the intervention. HRV was also monitored at rest and during sleep. RESULTS: After receiving the sleep-inducing juice intervention (FS), PSQI scores were significantly decreased (P < 0.001) and correlated with a significant decline in fatigue severity scale and visual analogue scale levels (P < 0.05; both). HRV indices of vagal activity were significantly improved during FS (P < 0.05), and no significant differences in N-FS were observed. Sleep efficiency and total sleep time increased significantly (P < 0.05) and sleep latency, total counts, sleep fragmentation index, and movement index, decreased significantly (P < 0.05, all 4) during FS, with no significant differences-observed during N-FS. CONCLUSIONS: This study results demonstrated that an 8-week course of sleep-inducing juice has led to improve sleep quality, suggesting an enhanced cardiac vagal tone during sleep. Thus, it could be a well-tolerated option for adults with disturbed sleep.

Objectives : This study was to observe clinical application of auto-microneedle therapy system (AMTS) in patients with peripheral facial paralysis. Methods : 27 peripheral facial paralysis patients were observed after taking AMTS at Facial Palsy Center, Kyung Hee University Oriental Medicine Hospital from March 1, 2011 to January 9, 2012. We assessed the symptoms of facial paralysis with Yanagihara unweighted grading system, Sunnybrook facial grading system(SBGS) and facial disability index(FDI), and observed adverse events and total safety of the treatment. Results : The scores of facial palsy scales increased after AMTS in Yanagihara grading system and Sunnybrook facial grading system. AMTS-related adverse events were mild pain(5.9%) and fatigue(3.5%), which needed no extra treatment. The total safety evaluation was between 'safe' and 'nearly safe' level. There were no other serious adverse events. In addition, patients were satisfied with subjective improvement including facial tingling and numbness. Conclusions : AMTS can be applied as an adjunctive treatment for patients with peripheral facial paralysis due to its safety and clinical usefulness. It is easier to stimulate wide skin area in a short time. Further clinical research is required to investigate the effectiveness of ATMS in a more rigorous RCTs.

The development of modern transportation technology has required many people in spaces (such as vehicle seats, airports, and train stations) for long periods. The public seats provided in these places are manufactured in a standard size; however, fatigue sets in if the seats are unsuitable for the person's physical size. For this reason, this study developed an air cushion vest that would enhance the comfort of vehicle seats. Passengers in vehicles, trains, airplanes, and buses were observed and surveyed to understand the demand for seat comfort. Our analysis found that the greatest source of discomfort was involuntary nodding of the head while asleep and discomfort around the waist area. For this reason, the air cushion vest was designed to support the head and the waist. The neck cushion of this vest was designed to strengthen head support to counter forward nodding because existing commercial neck cushions had no support for forward nodding. For the waist cushion, at lumbar and below-lumbar parts were chosen as the key parts to be supported, the cushion was designed to contain air at those parts. To cover the embedded waist cushion, the vest was designed to be long. The closure was constructed with zippers from the neck to waistline, and with invisible snaps from the waistline to the hemline so that the wearer could open them easily while seated. A subjective comfort evaluation was conducted to verify the effectiveness of the developed vest. In the test, the developed cushions received a better evaluation than cushions currently available on the market. The volume of the vest could be adjusted by the inflow and outflow of air. It was proven that the vest was effective in terms of comfort and portability. This shows that the developed vest could enhance passenger comfort while sitting on vehicle seats.

Vibrating test of vehicle component can be possible in lab-based simulators instead of field testing owing to the development of technology in control algorithm as well as computational process. Currently, Multi-Axial Simulation Table(MAST) is recommended as a vibrating equipment, which excites a target component for 3-directional translation and rotation motion simultaneously and hence, vibrational condition can be fully approximated to that of real road test. But, the vibration-free performance of target component is not guaranteed with MAST system, which is only simulator subjective to the operator. Rather, the reliability of multi-axial vibration test is dependent on the quality of input profile which should cover the required severity of vibrating condition on target component. In this paper, multi-axial vibration testing methodology of vehicle component is presented here, from data acquisition of vehicle accelerations to the obtaining the input profile of MAST using severe data at proving ground. To compare the severity of vibration condition, between real road test and proving ground one, energy principle of equivalent damage is proposed to calculate energy matrices of acceleration data and then, it is determined the optimal combination of special events on proving ground which is equivalent to real road test at the aspects of vibration fatigue using sequential searching optimal algorithm. To explain the vibration methodology clearly, seat and door component of vehicle are selected as a example.
