For over two thousand years, many artists and scientists have tried to understand or quantify the form of the perfect, ideal, or the most beautiful face both in art and in vivo(life). However, this mathematical relationship has been consistently and repeatedly reported to be present in beautiful things. This particular relationship is referred to as the golden ratio. It is a mathematical ratio of 1.618:1 that seems to appear recurrently in beautiful things in nature as well as in other things that are seen as beautiful. Dr. Marquardt made the facial golden mask that contains and includes all of the 1-dimensional and 2-dimensional geometric golden element formed from the golden ratio. The purpose of this study is to evaluate the usefulness of the golden facial mask. In our cases(n=40), the authors applied the facial golden mask to the preoperative and postoperative photographs, and scored each photograph. Compared with the average scores of the facial mask applied photographs and none applied photographs using non-parametric test, statistical significance was not checked (p>0.05). It means that the facial golden mask can be used for facial analysis. The facial golden mask is easy to apply, cheap and relatively objective. So, the authors introduce the one of useful facial analyses.

This study was designed to compare the performance of liquid-based preparation from the AutoCyte PREP with the conventional cervicovaginal smear in masked split-samples. In randomly selected 840 cases, the conventional smear was always prepared first, and the AutoCyte PREP used the residual cells on the collecting device. Parallel AutoCyte PREP slides and matched conventional smears were screened in a blind fashion. All abnormals and 10% random normal cases were reviewed by two pathologists in a blind fashion. The Bethesda System was used for reporting the diagnosis and specimen adequacy. The diagnoses from the two methods were agreed exactly in 767(91.3%) of 840 cases. The AutoCyte PREP demonstrated a 25% overall improvement in the detection of squamous intraepithelial lesion(SIL). The ratio of ASCUS to SIL was decreased as 0.45 compared with 1.00 of conventional smear. The AutoCyte PREP produced excellent cellular preservation and superior sensitivity for detection of atypical cells as compared to the conventional smear. It makes us to be able to subclassify ASCUS into from WNL to HSIL. We thought that the AutoCyte PREP method might contribute to increase the detection rate of abnormal cells than conventional methods.

BACKGROUND AND OBJECTIVES: Detection of auditory signals may be improved when maskers far from the frequency of the target signal are coherently amplitude-modulated. This improvement of signal detection is called comodulation masking release (CMR). In the CMR experiments, flankers have been usually arranged symmetrically. In practice, we will be confronted with a problem by using symmetric flankers due to the limited output of clinical audiometers, especially at high-frequency. We aimed to check whether flanker arrangement has any effect on the amount of CMR, especially when there is no flankers with a frequency higher than the signal. SUBJECTS AND METHODS: Eighteen normal hearing listeners ranging in age from 20 to 46 years old participated. Symmetric (2-2) and asymmetric (3-1 and 4-0) flankers were used and then the amount of CMR compared among them. RESULTS: Our results showed in the same numbers of flankers, there were no statistically CMR differences between symmetric and asymmetric arrangement. Also when we did not have a flanker at a frequency higher than the signal and all flankers were placed below the signal, there was no statistically difference with the symmetric arrangement. CONCLUSIONS: The asymmetry of the flankers and also omitting the flankers with a frequency higher than the signal, have no effect on CMR results. We concluded that CMR can be considered by using clinical audiometer.

Maxillary protraction is the conventional treatment for growing Class III patients with maxillary deficiency, but it has undesirable dental effects. The purpose of this report is to introduce an alternative modality of maxillary protraction in patients with dentoskeletal Class III malocclusion using a modified C-palatal plate connected with elastics to a face mask. This method improved skeletal measurements, corrected overjet, and slightly improved the profile. The patients may require definitive treatment in adolescence or adulthood. The modified C-palatal plate enables nonsurgical maxillary advancement with maximal skeletal effects and minimal dental side effects.
