The usefulness of constitutional diagnoses based on skin measurements has been established in oriental medicine. According to Sasang constitutional medicine, humans can be distinguished based on properties of skin's friction, thickness and elasticity. To quantify and standardize skin diagnosis, the present study designed an equipment for measuring skin elasticity of hand. But there were some noises in measuring skin elasticity such as measurement method, environment, operator and conditions of patient. So we considered a six sigma project for reducing the measurement errors. The project was followed to discipline process of five macro phases: Define, Measure, Analyze, Improve and Control(DMAIC). So, we could find the major factors which should be controled for stabilizing measurement system and we revised the SOP(Standard Operating Procedure) of the skin elasticity measurement.

To enhance our understanding of immunological stimulating effects through the pathway by which nitric oxide (NO) activity and alkaline phosphatase(ALP) enzyme activity from the marine algae, Ulva lactuca, we have investigated NO activity by using mouse RAW264.7 cell line. And ALP enzyme activity performed by spleen of ICR mouse. The results showed that NO activity of the $H_2O$ fraction is the most effective than activities of other solvent fractions.

To investigate oleic acid biodegradation, 47 fungal strains were tested with modified Czapek Dox broth media containing oleic acid, and their biodegradative activities were assayed by measuring the release of $[^14C]CO_2$ from the $^14C-$labeled oleic acid. After 72 h of cultivation, Aspergillus flavus, Aspergillus ochraceus, and Alternaria species metabolized approximately $25\%\;to\;35\%$ of the supplied oleic acid. The relationship between the fungal degradation of oleic acid and the fungal growth was also examined using 7 strains of Aspergillus niger. A. niger. YMC 0100 and YMC 0322 degraded about $26\%$ of the oleic acid after 72 h, while their germination ratios were more than $30\%$.

In this study, a new ensemble average technique was developed to measure cardiac output during treadmill exercise. Each dZ/dt peak (C point) was used as a starting point for ensemble averaging, instead of conventionally used R wave of ECG in order to prevent the peak dZ/dt waveform from blurring. In ease of using R wave as a reference, time interval from R wave to the peak of dZ/dt varies for each heart beat. Stroke volume, heart rate, and cardiac output of five male were successfully measured with Balke protocol using the new ensemble average technique.

Sinomenium acutum has been used for the treatment of rheumatoid arthritis, arrhythmia, and pain. We evaluated the quality of S. acutum extract by quantitatively analyzing its components such as sinomenine, magnoflorine and syringaresinol with the simultaneous determination method using HPLC-DAD. A total of 53 samples collected from different localities were evaluated with this quality evaluation method. Sinomenine, magnoflorine and syringaresinol from tested samples ranged from 0.0649~9.1050%, 0.7460~10.7590% and 0.0010~0.2441%, respectively. In the current study, we were able to exhibit the diverse quality of S. acutum samples collected from various locations using the simultaneous determination method.

An intelligent developer replenish system was developed for automatic film processor. The system detects the gray level of a developed film and determines the amount of the developer to be added to the system. Using the film darkness detection system, it was found that the film darkness is inversely proportional to the amount of light exposure, that the developer retrograde after developing certain number of films without replenishment and the number is dependent upon the parts of the body, and that the developer does not retrograde when 30 ml of developer is added after each chest film processing. The use of this system resulted in a decrease in the amount of developer by 40%.

본 논문에서는 뇌졸중 환자의 독립적인 재활운동이 가능할 수 있는 시스템을 제안한다. 뇌졸중은 뇌기능의 부분적 또는 전체적으로 급속히 발생한 장애가 상당 기간 이상 지속되는 상태를 의미한다. 이러한 뇌졸중은 상지 운동을 통해 대뇌 운동피질을 활성화하여 재활 할 수 있어, 의학 분야에서는 운동기구를 이용하여 뇌졸중 환자의 재활을 돕고 있다. 하지만 병원이 아닌 가정에서 운동을 하기에는 운동기구에 비용, 작업치료사의 부재와 같은 환경적인 측면으로 무리가 있다. 따라서 본 논문에서는 가정에서 환자가 독립적인 운동을 할 수 있게 MCU와 Android Application을 이용하여 의료진이 환자의 옆에 없더라도 운동이 가능하고 가이드를 제공하는 스마트한 재활운동기기를 개발하였다. 또한 기존의 재활운동기기는 단순히 운동만 할 수 있었다면, 본 연구에서는 Android Application에서 게임을 제공함으로써 보다 즐겁게 운동이 가능하여 재활의지 증가를 기대해볼 수 있다. 뿐만 아니라 환자의 운동 데이터가 실시간으로 저장되어 병원에서 의료진이 환자의 운동 상태를 파악할 수 있도록 구성함으로 써 향후 뇌졸중 환자의 재활연구분야에 도움이 될 것이라 생각한다.

Aucklandia lappa Decne (Compositae) has been used for treatment of abdominal pain, vomiting, diarrhea, chronic inflammation, and antibacterial effect. The quality of these herbs has been affected by many factors such as collection time, place, temperature, cultivation environment and manufacturing process. We used costunolide and dehydrocostuslactone as marker compounds for quality evaluation of rhizome of Aucklandia lappa. 66 samples of Aucklandia lappa were collected from those habitats in Korea and China. The developed HPLC-DAD method was applied to investigate for quality control of Aucklandia lappa samples. The average contents of the costunolide and dehydrocostuslactone were 2.3895% and 0.9258%, respectively. The principal component analysis (PCA) exhibited that classification of Aucklandia lappa according to origin not separated. Results of this study may be satisfactory applied to determination of content criteria of Aucklandia lappa.

발달 장애는 신체 및 정신이 해당하는 나이에 맞게 발달하지 않은 상태로, 다른 아동에 비해 신경정신과적 질환 발생 확률이 높기 때문에 발달장애 아동의 치료는 매우 중요하다. 그러나 주관적 판단에 의해 이루어지는 기존 작업치료의 경우, 정량적 성과 지표를 확인하기 힘들고 대상자 스스로 지속적으로 진행하기에 한계가 있다. 본 연구에서는 치료 모델을 가상 공간상에 구현하여 공간에 구애받지 않고 치료를 진행할 수 있으며, 수행 결과에 대한 자료를 정확하고 지속적으로 기록하며 확인할 수 있도록 하였다. 또한, AI 스피커를 통해 치료에 대한 피드백을 줌으로써, 대상자 스스로 실시하여 치료자의 개입을 줄여 심리적 부담을 덜어 더욱 정확한 수행이 이루어지도록 하였다.

Background: A spinal extension and intensive rehabilitation program reduced the symptoms and pain of kyphosis, and improved function. Objects: This study aimed to demonstrate the effect of a spine extension device on the degree of thoracic kyphosis and extension angles, confirm reduction of the kyphosis angle and an increase in flexibility. Methods: Thirteen adults were enrolled in the experiment, using the spine extension device, which was set to passively extend the spine. The angle between the spinous process of the first thoracic vertebra and the spinous process of the twelfth thoracic vertebra was measured by dual inclinometer before and after using the spine extension device. Results: In the static posture, the thoracic kyphosis decreased after using the spine extension device in the thoracic extension posture, and there was a significant difference (p < 0.05); thoracic extension angle increased with statistical significance (p < 0.05). Conclusion: In this study, the thoracic kyphosis angle and thoracic extension angle of the subjects before and after using spine extension device was compared and analyzed, which proved that the spine extension device can effectively improve the mobility of spinal extension.
