  • It is generally thought that the quality management and the six sigma management innovation are not applicable to service industry, which might be derived from some differences between service and manufacturing industries. However, both are substantially alike in some intrinsic attributes. KT is leading the Quality management and the six sigma innovation activities in service industry, especially among telecommunication companies in Korea. Six sigma management innovation has been fostered in KT within short period of time and played an important role in helping KT privatized successfully. The successful cases of six sigma innovation activities in KT could be introduced to other Korean companies in service industry.

  • Inclusion complexes of ketoconazole (KT) with ${\alpha}-$, ${\beta}-cyclodextrin$ (CD) and dimethyl-${\beta}-cyclodextrin$ $(DM{\beta}CD)$ in a molar ratio of 1:2 were prepared by freeze-drying and solvent evaporation methods. The interactions of KT with ${\alpha}-CD$, ${\beta}-CD$ and $DM{\beta}CD$ in aqueous solution and in solid state were investigated by solubility study, infrared (lR) spectroscopy and differential scanning calorimetry (DSC). The stability constant of $KT-DM{\beta}CD$ inclusion complex (lC) was found to be the largest among three inclusion complexes. Clear differences in IR spectra and DSC curves were observed between inclusion complexes and physical mixtures (PM) of KT-CDs. It was also shown by IR spectra and DSC curves that solvent evaporation method might be. superior to the freeze-drying method in preparing the inclusion complexes of KT-CDs. The dissolution rate of KT was markedly increased by inclusion complex formation with CDs in the buffer solution at pH 4.0 and pH 6.8. The mean dissolution time (MDT,min), which represents the rapidity of dissolution, was in the order of $KT-DM{\beta}CD$ IC (3.20) < $KT-{\beta}-CD$ IC (4.36) < $KT-{\alpha}-CD$ IC (6.99) < $KT-{\alpha}-CD$ PM (17.46)< $KT-{\beta}-CD$ PM (19.36) < $KT-{\beta}-CD$ PM (28.53). The dissolution rates of KT-CD ICsprepared by solvent evaporation method were faster than those of KT-CD ICs prepared by freeze-drying method.

  • Background: Kinesiology taping (KT) is a method that helps immediately increase muscle activation, strength and joint stability by being attached to various skeletal muscles and structures of the body. Objectives: To investigate the effect of KT applied below the hyolaryngeal complex on the movement of the hyolaryngeal complex during swallowing in patients with dysphagia after stroke. Design: One-group, pre-post design. Methods: Twenty individuals with dysphagia after stroke participated in this study. KT was applied to the sternum and both clavicles from the hyolaryngeal complex. We analyzed the motion of the hyolaryngeal complex during swallowing with and placebo KT and KT using the Image-J software with videofluoroscopic swallowing study. In addition, a 0-to-10 numerical rating self-report scale was used to check the required effort and resistance felt during swallowing. Results: KT condition showed that the anterior and superior movement of the hyoid bone during swallowing was significantly lower than placebo KT (P<.05, all). Also, KT condition showed that the anterior and superior movement of the larynx during swallowing was significantly lower than placebo KT (P<.05, all). In result of statistical comparison between KT group and placebo KT group, the KT group showed significantly higher self-report scale score than the placebo KT group in terms of two category; the required effort and resistance felt (P<.05, all). Conclusion: This study demonstrated that KT applied below the hyolaryngeal complex inhibits the anterior and superior movement of hyoid bone and larynx during swallowing of patients with dysphagia after stroke.
