Objectives : This study was aimed to figure out how effectively acupuncture treatment and herb-medicine work on patients with elevation of LFT value and lipid-obesity index. Methods : The subject were 23 patients visited to Dept. of Acupuncture and Moxibustion, Kwangdong Oriental Medicine Hospital, who complained chronic fatigue and wandering pain from Oct. 2007. to Oct. 2008. Before treatments, they were tested for LFT, total cholesterol, triglyceride, body fat ratio and obesity index. They were treated with Ganjeonggyeok acupuncture weekly for 1 month. During acupuncture treatments, we applied Sangkankunbi-tang to all patients twice a day. After 1 month, they were retested for LFT, total cholesterol, triglyceride, body fat ratio and obesity index. Results : 1. After treatments, we could get the result of dropping means of AST, ALT and $\gamma$-GTP value. Statistical significance of ALT and $\gamma$-GTP were recognized before and after treatments, but AST was not recognized. 2. After treatments, we also could get the result of dropping means of total cholesterol, triglyceride, body fat ratio and obesity index. Statistical significance of all values were recognized before and after treatments. 3. Among 23 patients, 10 cases were reported that they were not within normal limits at least one in AST, ALT and $\gamma$-GTP. After treatments of those patients, we could get the result of dropping means of AST, ALT and $\gamma$-GTP value. Statistical significance of all values were recognized before and after treatments. 4. Among 23 patients, 19 cases were reported that they were not within normal limits at least one in total cholesterol, triglyceride, body fat ratio and obesity index. After treatments of those patients, we could get the result of dropping means of total cholesterol, triglyceride, body fat ratio and obesity index. Statistical significance of all values were recognized before and after treatments. Conclusions : Though further study is necessary, our finding suggest that the conduction of Ganjeonggyeok acupuncture and Sangkankunbi-tang treatments have helped to decrease the figures of LFT and lipid-obesity index in patients.

In this study, we propose several simultaneous tests to detect the difference between means and variances for the two-sample problem when the underlying distribution is normal. For this, we apply the likelihood ratio principle and propose a likelihood ratio test. We then consider a union-intersection test after identifying the likelihood statistic, a product of two individual likelihood statistics, to test the individual sub-null hypotheses. By noting that the union-intersection test can be considered a simultaneous test with combination function, also we propose simultaneous tests with combination functions to combine individual tests for each sub-null hypothesis. We apply the permutation principle to obtain the null distributions. We then provide an example to illustrate our proposed procedure and compare the efficiency among the proposed tests through a simulation study. We discuss some interesting features related to the simultaneous test as concluding remarks. Finally we show the expression of the likelihood ratio statistic with a product of two individual likelihood ratio statistics.

Degenerative joint disease(DJD) has hun known as one of the diseases which affect the middleor old-aged people. But as orthodontists are getting interested in the adult orthodontics, it is not rare for them to meet the open-bite patients with the TMJ DJD in their clinics. The purpose of this article is to investigate the cephalometric characteristics of the open-bite cases with TMJ DJD. Twelve TMJ DJD patients($15.1\~39.5$ years old) were selected from the patients who visited Department of Orthodontics, Seoul National University Hospital. Cephalograms were taken and means from 60 measurements were compared by t-test with those of the fifty four healthy adults($20.0\~26.7$ years old) who have normal occlusion and TMJ. In this study male and female are compared respectively, for in the normal samples 26 measurements showed significant differences between the male and the female. The results and conclusions axe as follows: 1 In DJD group, ANB and Angle of convexity decreased, which means the retruding of the mandible. The interincisal angle was smaller than that of the normal group. The means of the overbite were -2.1mm in male and -3.0mm in female, and the means of the overjet were 5.6mm in male and 6.7mm in female. The profile was similar to that of Angle's Class II div.1 open-bite. 2. SN-GoMe and FMA increased in DJD but SN-PP and FH-PP did not show any significant difference. In TMJ DJD open-bite cases, the bony structure lower than the palatal plane seemed to play an important role in developing open-bite. 3. In DJD group, PH-ArGo, SArGo and Y-sxis angle increased significantly, but genial angle showed no significant difference. The means of hか were 50.1mm in male and 40.2mm in female, which were significantly smaller than those of the normal(56.5mm in male, 50.9mm in female). These findings seemed to indicate the posterior rotation of mandible resulted from the shortening of the ramus height. 4. Anterior faical height(AFH), upper anterior facial height(UAFH) and lower anterior facial height (LAEH) of DJD showed no significant increase as compared with those of the noraml group. There was no significant difference in the ratio of upper anterior facial height to lower anterior facial height(UAFH/LAFH). But, lower posterior facial height(LPFH) was significantly smaller than that of the normal group. 5. It was thought that the peculiar profile of the TMJ DJD open-bite was resulted from the posterior rotation of mandible as the ramus became short following the degerative destruction of of the condylar head and neck.

The quadrilateral analysis is a proportional analysis which evaluates the skeletal configuration of lower face on the relations between both jaws in the horizontal as we]1 as vortical dimensions. This study was undertaken to analyse the harmony and disharmony of quadrilateral patterns in normal occlusion and malocclusion. The present study was carried out on lateral cephalograms of 530 Korean children; the subjects consisted of 135 normal occlusions (63 male and 72 female), 105 Class II division 1 malocclusions (52 male and 53 female), 109 Class III malocclusions (50 male and 59 female), 91 hypodivergent facial types (44 male and 47 female) and 90 hyperdivergent facial types (45 male and 45 female). The following conclusions were reached: 1. Means and standard deviation in each group and sex were obtained from normal occlusion and malocclusion. 2. Quadrilateral mean diagram in normal occlusion was constructed for male and female, respectively. 3. In normal occlusion, 1:1 ratio exists between the maxillary base length (A' to Ptm') and mandibular base length (B' to J'), but lower facial height is targer than above. 4. Difference is effective to estimate the degrees of Class II and Class III malocclusion, and lower facial height (LFH) and sagittal angle is effective to recognize the hypodivergent and hyperdivergent facial type. 5. Quadrilateral analysis is able to visualize the anteroposterior and vertical dysplasia of lower face, and it is helpful to recognize certain problems in malocclusion.

Multivariate cumulative sum (CUSUM) control charts for simultaneously monitoring both means and variances under multivariate normal process are investigated. Performances of multivariate CUSUM schemes are evaluated for matched fixed sampling interval (FSI) and variable sampling interval (VSI) features in terms of average time to signal (ATS), average number of samples to signal (ANSS). Multivariate Shewhart charts are also considered to compare the properties of multivariate CUSUM charts. Numerical results show that presented CUSUM charts are more efficient than the corresponding Shewhart chart for small or moderate shifts and VSI feature with two sampling intervals is more efficient than FSI feature. When small changes in the production process have occurred, CUSUM chart with small reference values will be recommended in terms of the time to signal.

Because of the equivalence between control chart procedures and hypothesis testing, we propose to use likelihood ratio test (LRT) statistic $Z_i^2$ as the multivariate control statistic for simultaneous monitoring means of the multivariate normal process. Properties and comparisons of the proposed control charts are explored and conducted for matched fixed sampling interval (FSI) and variable sampling interval (VSI) with two sampling interval charts. The result of numerical comparisons shows that EWMA chart with two sampling interval procedure is more efficient than the corresponding FSI chart for small or moderate changes. When large shift of the process has occurred, we also found that Shewhart chart is more efficient than EWMA chart.

The protective effects of the aqueous MeOH extracts of stem and root Acanthopanax koreanum Nakai against oxidative stress were investigated. Anti-oxidant activity of the stem extract of A. koreanum was observed in the DPPH free radical scavenging $(IC_{50}=58.7\;{\mu}g/ml)$ and the SOD test $(IC_{50}=17.52\;{\mu}g/ml)$. According to data analysis of cell survival ratio of normal fibroblasts, the skin irritation by both extracts from A. koreanum was concerned. However, in the skin primary parch test, both extracts obtained Grade I, which means that there was no skin irritation. After induction of oxidative irritation, cell survival ratio of normal fibroblasts was also monitored and it turned out that stress-inducing group with both extracts had more increased cell survival ratio. The cell extension of the stress-inducing group treated with the stem extract was most dominant in morphological study. Based on these results, the stem extract of A. koreanum showed the protective effect against oxidative stress on normal fibroblast.
