Hearing impairement in varying degrees constitutes one of the most common disabilites affecting school aged children. Eight out of every 1,000 students under the age of twenty have significant hearing loss. Hearing disabilities range from slight to total loss of sound perception. Statistics indicate that only one out of every ten hearing impaired children will become deaf. Most motor activities can be included students may possess low levels of static and/ or dynamic balance, but the greatest majority possess normal motor and physical capabilities. All the hearing impaired youngsters should be properly assessed and given the identical testing batteries as normal children. Hearing impaired students have, essentialy, a communication handicap and suffer from inability to understand verbal instructions. All physical educators should be able to use minimal finger spelling and signing for hearing impaired students.

To investigate seed non destructive and fast determination technique utilizing near infrared reflectance spectroscopy (NIRs) for screening ultra high oleic (C18:1) and linoleic (C18:2) fatty acid content sesame varieties among genetic resources and lines of pedigree generations of cross and mutation breeding were carried out in National Institute of Crop Science (NICS). 150 among 378 landraces and introduced cultivars were released to analyse fatty acids by NIRs and gas chromatography (GC). Average content of each fatty acid was 9.64% in palmitic acid (C16:0), 4.73% in stearic acid (C18:0), 42.26% in oleic acid and 43.38% in linoleic acid by GC. The content range of each fatty acid was from 7.29 to 12.27% in palmitic, 6.49% from 2.39 to 8.88% in stearic, 12.59% of wider range compared to that of stearic and palmitic from 37.36 to 49.95% in oleic and of the widest from 30.60 to 47.40% in linoleic acid. Spectrums analyzed by NIRs were distributed from 400 to 2,500 nm wavelengths and varietal distribution of fatty acids were appeared as regular distribution. Varietal differences of oleic acid content good for food processing and human health by NIRs was 14.08% of which 1.49% wider range than that of GC from 38.31 to 52.39%. Varietal differences of linoleic acid content by NIRs was 16.41% of which 0.39% narrower range than that of GC from 30.60 to 47.01%. Varietal differences of oleic and linoleic acid content in NIRs analysis were appeared relatively similar inclination compared with those of GC. Partial least square regression (PLSR) among multiple variant regression (MVR) in NIRs calibration statistics was carried out in spectrum characteristics on the wavelength from 700 to 2,500 nm with oleic and linoleic acids. Correlation coefficient of root square (RSQ) in oleic acid content was 0.724 of which 72.4 percent of sample varieties among all distributed in the range of 0.570 percent of standard error when calibrated (SEC) which were considerably acceptable in statistic confidence significantly for analysis between NIRs and GC. Standard error of cross validation (SECV) of oleic acid was 0.725 of which distributed in the range of 0.725 percent standard error among the samples of mother population between analyzed value by NIRs analysis and analyzed value by GC. RSQ of linoleic acid content was 0.735 of which 73.5 percent of sample varieties among all distributed in the range of 0.643 percent of SEC. SECV of linoleic acid was 0.711 of which distributed in the range of 0.711 percent standard error among the samples of mother population between NIRs analysis and GC analysis. Consequently, adoption NIR analysis for fatty acids of oleic and linoleic instead that of GC was recognized statistically significant between NIRs and GC analysis through not only majority of samples distributed in the range of negligible SEC but also SECV. For enlarging and increasing statistic significance of NIRs analysis, wider range of fatty acids contented sesame germplasm should be kept on releasing additionally for increasing correlation coefficient of RSQ and reducing SEC and SECV in the future.

Application of genotype by environment (G × E) interaction would be used for identifying optimum test condition of the varietal adaptation in the establishment of breeding purpose. Yield and yield components were used to perform additive main effect and multiplicative interaction (AMMI) analysis. Significant difference for G × E interaction were observed for all variable examined. For yield, 0.18 of total sum of squares corresponded to G × E interaction. Correlation analysis was carried out between genotypic scores of the first interaction principal component axis (IPCA 1) for agronomic characters. Significant correlations were observed between IPCA 1 for yield and capsule bearing stem length (CBSL), number of capsule per plant (NOC). The biplot of grain yield means for IPCA1 which accounted for 34% of the variation in total treatment sums of squares showed different reaction according to G × E interaction, genotypes and environments. Taegu showed relatively lower positive IPCA1 scores, and it also showed smaller coefficient variation of yield mean where it is recommendable as a optimal site for the sesame cultivar adaptation and evaluation trial. In case of variables, Yangbaek and M1 showed relatively lower IPCA1 scores, but the score direction showed opposite each other on the graph. Ansan, Miryang1, Miryang4, and Miryang6 seemed to be similar group in view of yield response against IPCA1 scores. These results will be helpful to select experimental site for sesame in Korea to minimize G × E interaction for the selection of promising genotype with higher stability.

Tuberculin test revealed positive in 75% of cases. 4. Chest x-Ray revealed tuberculous lesion in 6 6.7% of all cases and miliary tuberculosis was found in 33.3% of all cases. 5. In 66.7% of cases leukocyte count in the CSF was 50∼500/㎣. In 75% of all cases, differential count of lymphocyte was over 75%. Protein level ranged from 50 to 300mg% in 83.3% of all cases. Sugar level in the cerebrospinal fluid was decreased below 40mg% in the 58.3% of all cases. 6. CT findings were as follows ⓐ obliteration of the basal cisterns were observed in 2 out of 7 cases (28.6%). ⓑ Intence abnormal contrast enhancement of the basal cistern were observed in 1 out of cases (14.3%). ⓒ Moderate to marked dilatation of both lateral ventricles were observed in 4 cases(57%) ⓓ I case of cerebral infarction was observed. 7. As for clinical stage of Tuberculous Meningitis 10 cases were in stage l & 2 on admission and all of them were recovered. 2 cases were in stage 3, 1 case died and 1 case recovered. Mortality rate was 8.3%.
