Objectives This study was conducted to suggest a standard operating procedure (SOP) in order to improve the reliability of tongue-image analysis system. Methods An affecting-factors list was made, which may affect the diagnostic parameters of the tongue-image analysis system. They were sub-classified into two groups: controllable and uncontrollable. Only the controllable factors, which could affect the results and easily set-up, were included into the SOP draft. Affecting factors control experiment was performed to investigate the effects of controllable factors, whose influence on diagnostic parameters of the tongue-image analysis system is ambiguous: rehearsal for tongue extrusion; alignment of camera axis; and presentation of a guideline. Three subjects volunteered for this experiment. Each of three variables was implemented twice in a random order by two operators on the subjects. Finally, 96 tongue images obtained in the aggregate. The diagnostic parameter set as a primary outcome in this experiment was the percentage of tongue coating. Results All of the control variables were not significant in both operators; however, the presentation of a guideline was relatively more affect than two other variables. Interaction effects among the variables were also insignificant. Therefore, the presentation of a guideline was included in the final SOP and the other variables were not included. Conclusions We suggested the SOP which could be used for both experimenter and subject. Moreover, Each of the SOPs applied to various types of tongue-image analysis system should be developed in order to improve the reliability.

Objectives : The objective is that we measure and analyze Pulse-Respiration Ratio and Body Composition Analysis to study the correlation between both. Methods : First, after subjects take a rest over 10 minutes, we measure their electrocardiogram and respiration pattern through which we take average peak interval to calculate an average pulse cycle and a respiration cycle. An average respiration cycle divided by an average Pulse Rate gives Pulse-Respiration Ratio. Next, we draw out 22 Body Composition Analysis indicators by using In-Body 720 model. Last, we analyze and take statistics on them by using SPSS 13.0 program. Results : Negative is the correlation between P/R Ratio and Body Composition Analysis indicator like fatness degree, body fat volume, body fat rate, abdominal fatness, BMI. Conclusions : 1. The higher P/R Ratio the more likely to be thin, the lower P/R Ratio the more likely to be fat. 2. We separately analyze P/R Ratio depending on each breathing frequency and pulse frequency to find out that breathing frequency has great influence and that breathing frequency decides the fatness degree. 3. In study on the correlation between P/R Ratio and Body Composition Analysis, fatness degree, in-body fat volume, in-body fat rate, BMI are the related indicators, which shows the connection with the fatness indicators. 4. In study on the correlation between Han-Yeol [寒熱] grade and Body Composition Analysis indicators, the result is that Han[寒] has no connection and that only Yeol[熱] grade has something to do with it, which means the higher heat symptom subjects have, the more basic metabolism volume and muscular build they have.

Panax notoginseng exhibit several beneficial effects including anti-oxidant effects. P. notoginseng is used as a therapeutic agent to stop haemorrhages and a tonic to promoted health in Korean and Chinese medicine. The pharmacokinetic profiles of the main P. notoginseng are still not accurately investigated. The exact mechanism of the anti-oxidant activitys of water extracts of P. notoginseng, however, has not been determined. in present study, I examined the effects of water extracts of P. notoginseng on high cholesterol diet atherosclerosis-induced rats in serum and abdominal aorta. A total of 3-week old 9 male rats of Sprague-Dawley were divided into 3 groups and fed with the basal diet (normal group), high cholesterol diet (atherosclerosis induced group) for 8 weeks, high cholesterol diet supplemented with water extracts of P. notoginseng (P. notoginseng group) for 4 weeks. And rats were sacrificed, serum lipid level, abodominal aortic anti-oxidant activities and lipid peroxide were measured. These results indicated that serum total cholesterl, LDL-cholesterol, triglycerides concentration significently lowered in P. notoginseng group than high cholesterol diet group. But HDL-cholesterol concentraion significently higher in P. notoginseng group than high cholesterol feed group. And abdominal aortic xanthine oxidase activity was significantly reduced by dietary water extracts of P. notoginseng supplementation (p<0.05) Also abdominal aortic superoxide dismutase, catalase, glutathione peroxidase activities were significantly increased by dietary water extracts of P. notoginseng supplementation (p<0.05) Especially, abdominal aortic level of lipid peroxide tended to increase in high cholesterol feed group, but water extract of P. notoginseng intake reduced the value (p<0.05).

Objectives The purpose of this study was to examine the daily lifestyle of Vietnamese immigrant women and to find out if they could affect health-related quality of life improvement. Methods The subjects of this study were 273 women who immigrated to Korea from Vietnam. This study was conducted at Daejeon and nearby Healthy Family Support Centers from September 2019 to January 2020 with the cooperation of the Daejeon City Healthy Family Support Center. Correlation analysis was performed between lifestyle and quality of life, and ANOVA analysis was performed to confirm the difference in health-related quality of life scores for each subgroup of dietary nutrition, sleep quality, and physical activity. A regression analysis was conducted to investigate the contribution of dietary nutrition, sleep quality, and physical activity to the quality of life of Vietnamese immigrant women. The significance level was p<0.05. Results Physical activity showed significant correlations with Euro Quality of Life -Visual Analogue Scale (EQ VAS), sleep quality with EQ VAS and Euro Quality of Life-5Dimension (EQ-5D) Index, and dietary nutrition with EQ-5D Index. There were significant differences in EQ VAS and EQ-5D Index scores for each sleep quality subgroup, and a significant difference in EQ VAS scores for each activity subgroup. The quality of sleep was found to have the greatest effect on EQ VAS and EQ Index of Vietnamese immigrant women, and physical activity on EQ VAS and dietary nutrition had some influence on EQ-5D Index. Conclusions Quality of sleep is closely related to health-related quality of life, and plays an important role in health-related quality of life for Vietnamese immigrant women.

The problem of selecting variables in the presence of outliers is considered. Variable selection and outlier detection are not separable problems because each observation affects the fitted regression equation differently and has a different influence on each variable. We suggest a simultaneous method for variable selection and outlier detection in a linear regression model. The suggested procedure uses a sequential method to detect outliers and uses all possible subset regressions for model selections. A simplified version of the procedure is also proposed to reduce the computational burden. The procedures are compared to other variable selection methods using real data sets known to contain outliers. Examples show that the proposed procedures are effective and superior to robust algorithms in selecting the best model.

Emission lines ratios were used for diagnostics of and excited level densities in low-temperature plasmas. In this work, an optical emission spectroscopy (OES) was used to determine the electron temperature and metastable level densities in low-pressure inductively coupled plasma. The emission spectroscopy method was based on a simple collisional-radiative model. The selected lines of the Ar(4p to 4s) were influenced by the radiation trapping at relatively high pressures where the plasma become optically thick. To quantify this effect, a pressure dependence factor ${\alpha}$(P) was derived by using corrections for the measured intensities. It was found that the lower metastable level densities were obtained when ${\alpha}$(P) increased with the increasing discharge pressure. The effect of non-Maxwellian electron energy distribution functions (EEDFs) on the metastables was also presented and discussed.

Recently, the digital healthcare technologies including non-invasive diagnostics based on Internet of Things (IOT) are getting attention. Human exhaled breath contains a variety of volatile organic compounds (VOCs), which can provide information of malfunctions of the body and presence of a specific disease. Detection of VOCs in exhaled breath using gas sensors are easy to use, safe, and cost-effective. However, accurate diagnosis of diseases is challenging because changes in concentration of VOCs are extremely small and lots of body factors directly or indirectly influence to the conditions. To overcome the limitations, highly selective nanosensors and artificial intelligent electronic nose (E-nose) systems have been mainly researched in recent decades. This review provides brief reviews of the recent studies for diabetes and lung cancer diagnosis using nanosensors and E-nose systems.
