  • This study was prepared to investigate the correlation between Sasang constitutional groups and voice characteristics using voice analysis system(in this study, CSL). I focused on the voice characteristics in terms of harmonics, Formant frequency and Formant Bandwidth. The subjects were 71 males. I classified them into three groups, that is Soeumin group, Soyangin group and Taeumin group. The classification method of Constitution used two ways, QSCCII(Questionnarie for the Sasang Constitution Classification II) and Interview with a specialist in Sasang Constitution. So 71 people were categorized into 31 Soeumin(people), 18 Soyangin(people) and 22 Taeumin(people). Pitch is approximately similar to the fundamental frequency(F0) in voices. Shimmer in dB gives an evaluation of the period-to-period variability of the peak-to-peak amplitude within the analyzed voice sample. FFT(Fast Fourier Transform) method in CSL can display sampled voices into harmonics. H1 is the first peak and h2 is the second peak in the harmonics. The amplitude difference of h1 and h2(h1-h2) can be explained as the speaker's phonation type, And Formant frequency and bandwidth can be explained as the speaker's vocal tract. So I checked the harmonics and Formant frequency and Bandwidth as the voice parameters. First I have captured /e/ voices from all subjects using microphone. And then I analyzed /e/ voices with CSL. Power Spectrum and Formant History is the menu in the CSL which can display harmonics and Formant frequency and bandwidth. The results about the correlation between Sasang Constitutional Groups and voice parameters are as follows; 1. There is no significant amplitude difference of harmonics(h1-h2) among three groups. 2. There is the significant difference between Soeumin Group and Soyangin Group in Formant Frequency 1 and Formant Bandwidth 1(p<0.05). Any other parameters have no significance. I assume that Soyangin Group has clearer and brighter voice than Soeumin Group according to the Formant Bandwidth difference. And I think its result has coincidence with the context of "Dongyi Suse Bowon" and "Sasangimhejinam".

  • Indentifying anomaly correlations between data sets is the basis for rationalizig geopotential interpretation and theory. A procedure is presented that constitutes an effective process for identifying correlative features between the two or more geopotential data sets. Anomaly features that show direct, inverse, or no correlations between the data may be separated by applying filters in the frequency domains of the data sets. The correlation filter passes or rejects wavenumbers between co-registered data sets based on the correlation coefficient between common wavenumbers as given by the cosine of their phase difference. This study includes an example of Magsat magnetic anomaly profile that illustrates the usefulness of the procedure for extracting correlative features between the data sets.

  • Objectives: We conducted a literature study on the treatment trends in China to find out the possibility of Oriental medicine treatment of atypical hyperplasia of breast (AHB). Methods: RCTs (randomized controlled trial) on AHB were collected from CNKI (China National Knowledge Infrastructure). The search words were "乳腺增生", "乳腺囊性增生", "乳癖", "中医", "中药" and "中西医结合". The search period was limited from July 2006 to May 2017. Finally, we selected 107 RCTs which were clinical studies to find out the effectiveness of Chinese herbal medicine in comparison with Western medicine. After reviewing, we investigated Chinese herbal medication guide, Chinese treatment method and prescriptions. And the correlation between the treatments and the medicinal herbs was investigated to be useful in the clinical practice. Results: 1. The administration of herbal medicine was 58.9 percent in 63 cases, followed by menstrual cycles, and 41.1 percent in 44 cases, regardless of menstrual cycles. 2. In the basic frequency analysis between the treatment and the medicinal herb, the frequency of dissipate binds (散結) was the highest. Next, there was a high frequency of therapies such as activating blood-activating (活血), relieve pain (止痛), soothe the liver (疏肝), regulate qi (理氣), resolve phlegm (化痰), soften hardness (軟堅), resolve depression (解鬱), move qi (行氣) of frequency was high. In herbal medicine, bupleuri radix (柴胡), cyperi rhizoma (香附子), angelicae gigantis radix (當歸), fritillaria thunbergii bulb (貝母), paeoniae radix alba (白芍藥), prunellae spica (夏枯草), corydalis rhizoma (玄胡索) showed high frequency. 3. We finded out the correlation between the frequent treatment methods and the medicinal herbs using Text Mining. Conclusions: These findings are thought to help implement Korean traditional medicine treatments for AHB.

  • The purpose of this study was to investigate job stressors, job stress symptoms, and job performance of workers in fashion industry. The data were obtained from questionnaire completed by 529 workers who were employed in textile or clothing manufactures located in Seoul, Daegu, Busan, and Masan area. The SPSS package was used for data analysis which included frequency, mean, correlation, and factor analysis. Job stressors consisted of environmental related stressors, job related stressors(task characteristics and role characteristics) and organization related stressors(organization climate and career development). Most of job stressors were significantly correlated with job stress symptoms but their correlation coefficients were low. Among job stressors, quantitative work overload was found to be a major stressor. Workers in fashion industry appeared to evaluate their job performance relatively good. Also, it was found that behavioral and psychological symptoms were negatively correlated with job performance.

  • A new method called fuzzy factor method for the stationary stochastic response analysis of fuzzy truss with global fuzzy structural parameters is presented in this paper. Considering the fuzziness of the structural physical parameters and geometric dimensions simultaneously, the fuzzy correlation function matrix of structural displacement response in time domain is derived by using the fuzzy factor method and the optimization method, the fuzzy mean square values of the structural displacement and stress response in the frequency domain are then developed with the fuzzy factor method. The influences of the fuzziness of structural parameters on the fuzziness of mean square values of the displacement and stress response are inspected via an example and some important conclusions are obtained. Finally, the example is simulated by Monte-Carlo method and the results of the two methods are close, which verified the feasibility of the method given in this paper.
