Purpose : The purpose of this study is to know the temperature difference between hysterectomy patients and non-hysterectomy patients. Methods : We studied 45 who had and 45 non-hysterectomy visiting ${\bigcirc}{\bigcirc}$ medical center from January 1st 2010 to December 31st 2010. We measured 3 points temperature of specific acupoints-Chonjung(CV17), Chungwan(CV12), Kwanwon(CV4) by DITI in each group. And then we checked the difference of temperature between CV17 and CV4, CV12 and CV4. For statistics, we used Independent T-test and SPSS version 17.0 for windows. Results : There is no statistically differences between hysterectomy group and non-hysterectomy group on CV17, CV12, CV4 and CV12-CV4 temperature. There is statistically significant difference between group and group on CV17-CV4 temperature. Conclusion : The result showed that the difference between Chonjung(CV17) and Kwanwon(CV4) is higher in group than non-hysterectomy group. Further study will be needed.

Purpose: We intended to observe the relations between Chiljehyangbuhwan and abdominal temperature according to primary dysmenorrhea severity. Methods: We selected the 100 primary dysmenorrhea patients by the screening tests (first screening test-inquiry, second screening test-clinical test, additionally WHR (Waist-to-Hip ratio) by Inbody 2.0). By the fixed blocked randomization and double blind method, Chiljehyangbuhwan or placebo was administered for 1 menstration period. Finally, 69 patients remainded. Before and after administration, we measured 4 points abdominal temperature (Chon-jung(CV17), Chung-wan(CV12), Kwan-won(CV4), Chung-guk(CV3)) by DITI (DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV12 / CV17 and CV4 / CV17 and CV3 / CV12 and CV4 / CV12 and CV3. After that, we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by VRS (verbal rating scale) and MVRS (multidimensional verbal rating scale). In dysmenorrhea severity, we standardized scale score and 3-group-severity by score (mild, moderate, severe). For statistics, we used Pearson correlations and Spearman's rho correlations, SPSS 11.0 for windows. Results: In case of MVRS, Chiljehyangbuhwan was correlated to ${\Delta}T$ (CV12 and CV3 / CV12 and CV4). In case of VRS, Chiljehyangbuhwan was not correlated to ${\Delta}T$. Statistically they showed significant result (p<0.05). Conclusion: The primary dysmenorrhea patients showed that severity by MVRS was connected with ${\Delta}T$ (CV12 and CV3 / CV12 and CV4) after Chiljehyangbuhwan administration. So we can consider Chiljehyangbuhwan effects the abdominal temperature according primary dysmenorrhea severity.

Objectives : The aim of this study was to assess the quantitative characteristics of pressure pain threshold (PPT) and pressure depth (PD) at the abdominal conception vessel (CV) acupoints according to subjective digestive status and digestive discomfort levels, accomplished by comparing a large group of healthy men and women, using the modified digital algometer. Methods : A total of 1,504 healthy adults aged 19 years or older participated in this study. A questionnaire was administered to evaluate participants' digestive status and discomfort. PPT (kgf/cm²/s) and PD (mm) measurements were obtained at CV14, CV12, and CV4 acupoints using a modified digital algometer. General characteristics were analyzed using the chi-square test, and differences in PPT and PD were assessed using two-sample t-tests and ANCOVA. Results : Significant difference in PPT was found based on digestive status at CV14 and CV12 for both sexes, and in PD at CV14 for women. Women exhibited significant difference in PPT based on digestive discomfort at CV14, CV12, and CV4, while men showed significant difference at CV14 and CV12. Significant difference in PD was observed at CV14 and CV4 among women. Even after adjusting for age and body mass index, significant difference persisted in PPT based on digestive discomfort at CV14 and CV12 for both sexes. PD exhibited significant differences at CV14, CV12, and CV4 among women. Conclusions : Using the modified digital algometer, this study showed the significant difference of pressure pain threshold at the CV14 and CV12 acupoints for subjective digestive discomfort levels in healthy men and women.

We investigated if Chlorella vulgaris (CV) has protective effects on cadmium (Cd) induced liver damage in male Sprague-Dawley (SD) rats. Forty rats, aged 5 weeks old and weighed 90-110g, were divided into a control (with Cd free water), 50 ppm of $CdCl_2$ in drinking water treated groups (Chlorella 0% diet group (Cd/CV0%), Chlorella 5% diet group (Cd/CV5%) or Chlorella 10% diet group (Cd/CV10%). All the rats had freely access to water and diet for 8 weeks. The results show that body weight gain and relative liver weight had significantly lower in Cd/CV0%-treated group than in Cd/CV-treated groups. Hepatic Cd contents showed significantly less by feeding CV (P<0.05). Cd/CV0%-treated rats had significantly (P<0.05) higher hepatic T-MTs, and Cd-MTs concentrations, compared to Cd/CV5% or Cd/CV10% treated rats. The MT I/II mRNA was expressed in the liver of all experimental rats. Its expression was more increased in Cd/CV5%- or Cd/CV10%-treated rats, compared to control and Cd-treated rats. Thus, this study suggested that CV would have a protective effect on Cd-treated liver injury by the reduction of Cd concentrations and stimulation of Cd-MT binds in the liver. However, more studies are needed to identify the proper mechanism of CV and liver toxicity.

The effect of Chlorella vulgaris (CV) on the urinary excretion of di-ortho PCB congeners (PCB-138, -153) was investigated. Sprague-Dawley rats (6-weeks-old, n=10 rats/group) were randomly divided into one control (0CV) or 2% CV (2CV) or 5% CV (5CV) or 10% CV (10CV) groups, respectively. Composition of normal and chlorella meal-based diet were made up of 30% casein, 15% cornstarch, 50% sucrose, 5% cellulose, 5% coconut oil, 3.5% mineral mixture, 1 % vitamin mixture. All rats had free access to water and diet for 4 weeks. A significant increase in both PCB 138 and 153 in urinary level was detected in CV fed groups, 540% and 167% for 2CV, 155% and 89% for 5CV, 114% and 144% for 10CV group, respectively, when compared with their controls. These findings suggest that CV may have potential to eliminate body burden levels of dioxin-like PCB compounds.

Purpose: We intended to observe the relations between Chiljehyangbuhwan and abdominal & palmar temperature according to primary dysmenorrhea severity. Methods: We selected the 100 primary dysmenorrhea patients by the screening tests (first screening test-inquiry, second screening test-clinical test. additionally WHR (Waist-to-Hip ratio) by Inbody 2.0). By the fixed blocked randomization and double blind method, Chiljehyangbuhwan or placebo was administered for 1 menstration period. Finally, 69 patients remainded. Before and after administration, we measured 4 points abdominal temperature (Chon-jung (CV17), Chung-wan(CV12), Kwan-won(CV4). Chung-guk(CV3)) by DITI(DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV12/CV17 and CV4/CV17 and CV3/CV12 and CV4/CV12 and CV3. Also, we measured 2 points (palmar region, upper front of forearm) for the difference of palmar temperature $({\Delta}T)$. Then, we checked palmar temperature minus upper front of forearm temperature and took an average of right and left ${\Delta}T.$ After that. we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by VRS (verbal rating scale) and MVRS (multidimensional verbal rating scale). In dysmenorrhea severity. we standardized scale score and 3-group-severity by score (mild, moderate. severe). Besides, we compared palmar ${\Delta}T$ with abdominal ${\Delta}T$. For statistics, we used ANOVA and Spearman's rho correlations. SPSS 13.0 for windows. Results: In case of MVRS, though Chiljehyangbuhwan was correlated to abdominal ${\Delta}T$(CV12 and CV3/CV12 and CV4). it was not correlated to palmar ${\Delta}T$. In case of VRS, though Chiljehyangbuhwan was not correlated to abdominal ${\Delta}T$. it was correlated to palmar ${\Delta}T$. However. palmar ${\Delta}T$ was not correlated to abdominal ${\Delta}T$. Statistically they showed significant result (p<0.05). Conclusion: The primary dysmenorrhea patients showed that severity by MVRS was connected with abdominal ${\Delta}T$ (CV12 and CV3/CV12 and CV4) and severity by VRS was connected with palmar ${\Delta}T$ after Chiljehyangbuhwan administration. So we can consider Chiljehyangbuhwan partially effects the abdominal & palmar temperature according primary dysmenorrhea severity. However, palmar temperature was not correlated to abdominal temperature. Therefore, we need further study.

Purpose: We intended to research the relations between abdominal temperature and primary dysmenorrhea severity. Methods: We selected the 95 primary dysmenorrhea patients by means of screening test (first screening test-inquiry, second screening test-clinical test, additionally Waist-to-Hip ratio (WHR) by Inbody 2.0). We measured 4 points abdominal temperature (Chon-jung(CV17), Chung-wan(CV12), Kwan-won(CV4), Chung-guk(CV3)) by DITI (DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV4 / CV17 and CV3 / CV12 and CV4 / CV12 and CV3. After that, we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by multidimensional scales (verbal rating scale modified from the one devised by Bibe roglu & Berhrman(VRS; B&B), multidimensional verbal rating scale by Andersch & Milsom(MVRS)). In dysmenorrhea severity, we standardized scale score and 3-group-severity by score (mild, moderate, severe). For statistics, we used Pearson correlations and Spearman's rho correlations, SPSS 11.0 for windows. Results: In case of MVRS, MVRS score and 3-group-severity were not correlated to ${\Delta}T$. In case of VRS; B&B, VRS; B&B score was correlated to ${\Delta}T$ (CV12 and CV4 / CV12 and CV3) and 3-group-severity was correlated to ${\Delta}T$ (CV12 and CV3). Statistically they showed significant result (p<0.05). So we can consider that ${\Delta}T$ (CV12 and CV3) and the primary dysmenorrhea severity by VRS; B&B are most correlated. Conclusion: The primary dysmenorrhea patients showed that severity by VRS; B&B was connected with ${\Delta}T$ (CV12 and CV3). So we can consider DITI as primary dysmenorrhea evaluation instrument and must further research measurement points for the exact primary dysmenorrhea evaluation by DITI.

When the production run is short and process parameters change frequently, it is difficult to monitor the process using traditional control charts. In such a case, the coefficient of variation (CV) is very useful for monitoring the process variability. The CV control chart is an effective tool to control the mean and variability of process simultaneously. The CV control chart, however, is not sensitive at small shifts in the magnitude of CV. The CV-EWMA(exponentially weighted moving average) control chart which was developed recently is effective in detecting a small shifts of CV. Since the CV-EWMA control chart scheme can be viewed as a weighted average of all past and current CV values, it is very sensitive to small change of mean and variability of the process. In this paper, we propose an FIR(Fast initial response) CV-EWMA control chart to improve the sensitivity of a CV-EWMA scheme at process start-up or out-of-control process. Moreover, we suggest the values of design parameters and show the results of the performance study of FIR CV-EWMA control chart by the use of average run length(ARL). Also, we compared the performance of FIR CV-EWMA control chart with that of the CV-EWMA control chart and we found that the CV-EWMA control chart gives longer in-control ARL and much shorter out-of-control ARL.

Objective : This study was designed to investigate the effects of electro-acupuncture(EA) and moxibustion at CV13, CV12, CV10 and ST36 serum gastin level in rats. Methods : The present study was conducted to see the effects produced by combined electro-acupuncture(EA) and moxibustion using four different acupoints on serum gastrin level in rats. Electro-acupuncture (2 Hz, intensity ; 10 times muscle twitch threshold) was applied for 30 minutes to ST36 under halothane anesthesia. Moxibustion ($1.6{\pm}0.3mg$, 5 times of a day) was applied during 3 days to CV13, CV12, CV10 under halothane anesthesia. Results : Both of EA applied to the ST 36 and Moxibustion applied to the CV10, CV12 decreased serum gastrin level significantly. And the effect of combined EA at ST36 and moxibustion at CV10 was shown stronger effect than each singular stimulus of EA at ST36 and moxibustion at CV10. These data suggest that both of EA and moxibustion at specific acupoints produce change of serum gastrin level in rats and combined EA and moxibustion was shown quite effect than each singular stimulus.
