  • This study was carried out to assess whether the addition of myo-inositol to maturation medium could improve porcine oocyte maturation in vitro. Oocytes were cultured for the first 22 h in Witten's medium containing 10IU/$m\ell$ PMSG, 10 IU/$m\ell$ HCG supplemented with or without myo-inositol. Subsequently, they were cultured for additional 22 h in Witten's medium without hormone supplemented with or without myo-inositol. When the porcine oocytes were cultured in maturation medium containing myo-inositol, the proportion of metaphase II oocytes 44h after culture was higher in the myo-inositol group(P<0.05). To study effects of cumulus cell on the maturation induced by myo-inositol, we examined the maturation status of cumulus-enclosed or cumulus-denuded porcine follicular oocytes. The rates of maturation were significantly higher in the cumulus-enclosed oocytes(P<0.05). However, the maturation rates of cumulus-denuded oocytes cultured in medium containing myo-inositol were higher than those of control group(P<0.05). Our results suggest that myo-inositol may affect meiotic progression of porcine follicular oocytes and supplementation of myo-inositol in maturation medium may be useful for the in vitro maturation of porcine follicular oocytes.

  • A volume integral equation method(VIEM) is applied for the effective analysis of elastic wave scattering problems in unbounded solids containing general anisotropic inclusions. It should be noted that this newly developed numerical method does not require the Green's function for anisotropic inclusions to solve this class of problems since only the Green's function for the unbounded isotropic matrix is Involved In their formulation for the analysis. nis new method can also be applied to general two-dimensional elastodynamic problems with arbitrary shapes and number of anisotropic inclusions. Through the analysis of plane elastodynamic problems in unbounded isotropic matrix with an orthotropic inclusion, it is established that this new method is very accurate and effective for solving plane elastic problems in unbounded solids containing general anisotropic inclusions.

  • This study provides the underlying data on the inclusion of medical technologists in the category of medical personnel. Medical personnel are defined in the Medical Service Act as physicians, dentists, oriental medicine doctors, midwives, and nurses. In the act, medical technologists shall be classified into clinical laboratory technologists (clinical pathology technologists in the Korean language), radiological technologists, physical therapists, occupational therapists, dental technologists, and dental hygienists. Although South Korea's medical personnel do not include medical technologists, Japan and Taiwan define them as medical personnel. Various standard occupational classification such as International Standard Classification of Occupations 2008, Korean Standard Classification of Occupations 2017, Japan Standard Occupational Classification 2009, Taiwan Standard Occupational Classification 2010, and USA Standard Occupational Classification 2018 were compared. The education system for medical health technologists was explained to include 4-year university and 3-year junior college programs. The roles of medical technologists in medical practice, therapy, and medical assistance were outlined. These basic materials incorporate the need for discussions about the meaning of including medical technologists in the type of medical personnel. These discussions will contribute to the legalization of medical technologists' professionality with regard to their inclusion in the type of medical personnel.

  • Structure factor는 위치를 포함한 electron density를 알면 계산되고 역으로 electron density는 phase를 포함한 structure factor를 알면 작도할수 있으므로 structure factor와 electron density는 서로 Fourier transform이다.
