Purpose: The purpose of the present study was to develop lists of phoneme perception tests for school-aged children.Methods: The 127 initial and 94 final consonant test items were modified by the difficulty level (reduced the number for the multiple-choice and controlled familiarity of target words and foil words). The validity of the results for normal hearing children was evaluated. Through discussions by experts in various fields, the target word list was revised. Words with a low percentage (<90%) of correct answers, vowel-consonant in an initial consonant test item, and consonant-vowel (CV) in final consonant item were eliminated and produced the last revised consonant perception test item for school-aged children.Results: The consonant test item consisted of three multiple-choice words type of consonant-vowel-consonant or CV. The 50 initial and 25 final consonant perception test items included the high degree of familiarity, corresponding frequency of phonemes for daily life speech sounds of children.Conclusion: To analyze the phoneme perception ability of school-age children by listening and to evaluate phoneme errors in children with congenital high frequency hearing loss, the results of this study are useful.

Preliminary Study

To determine how much the exercise program success rate, a valid and reliable test tool is needed. In this study, the researcher aims to develop a smash skill test model in badminton. The method in this study is a development research method with a sample size of 121 athletes. The steps taken in this research include (1) preliminary study (literature study and field study), (2) planning (conducting analysis), (3) initial draft design, (4) validation of the draft, (5) testing of group products minor and revisions, (6) large group trials and revisions, (7) final results. This study involved academicians and badminton practitioners with an “excellent” rating, which reached an average score of 3.66. This result research is a product of the development of a smash skill test model in badminton. This study concludes that the smash skill test’s resulting form is valid and reliable, with a validity score of 0.688 and reliability of 0.870.

Hormonal Therapies

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.

Preliminary Study

A new strain of mice, which had arisen by mutation from a dystrophic mouse colony was designated ‘mdx’, because the genetic defect, which manifests itself in brief periods of muscle destruction followed by episodes of muscle regeneration appears to be X-linked. Further studies of histopathological changes in muscle from ‘mdx’ mice at the light microscopic or electron microscopic levels have been published, but only one preliminary study has been on the tibialis anterior (TA) of ‘mdx’ mice less than four weeks old. Lesions in the ‘mdx’ mice vary between different muscles, and centronucleation of fibers in all muscles studied so far appears to be especially prominent in older mice. Lesions in young ‘mdx’ mice have not been studied extensively, and the results appear to be at variance with one another. The degenerative and regenerative aspects of the lesions in the TA of 23 to 26-day-old ‘mdx’ mice appear to vary quantitatively.

Preliminary Study

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.
