To evaluate the ewe reproductive performances of three Iranian local sheep breeds, namely Moghani, Chal and Zel, 27 rams and 473 ewes were used as the foundation flock in a crossbreeding program. The three breeds were crossed amongst themselves reciprocally. Ram breed and ewe breed showed a two-way interaction on apparent fertility. The Zel ewes showed higher fertility than the Chal and Moghani ewes (94.4 vs 77.3 and 84.6%). Prolificacy among main and individual mating groups were not significantly different (p>0.05). Zel ewes were 22.3 and 14.8% more reproductive (p<0.05) than Chal and Moghani ewes, respectively. Zel and Moghani ewes showed higher (p<0.05) ewe productivity than Chal ewes. Ram breed had a significant (p<0.05) effect on ewe efficiency. The Zel rams were not completely successful to mate with Chal ewes, this caused a to way-interaction between ram and ewe breeds. The Zel ewes mated with Chal and Moghani rams showed 26.1 and 28.5% more efficiency than those mated with Zel rams. This observation strongly supports the use of crossbreeding to improve the efficiency of the Zel ewes. With decreasing lamb mortality, through supplemented feeding of lambs in pre-weaning period, and increasing litter weight, through crossbreeding, it should be possible to improve the efficiency of Zel ewes even better than Chal and Moghani ewes. Small body size of Zel ewes that needs the lower maintenance requirements would be a well advantageous to using Zel ewes as the dam herd to produce commercial lambs in north area of Iran.

Due to a mistranslation of Sanskrit to Chinese, East Asian Buddhist community misunderstands the original meaning of the fundamental word, 'sachal(寺刹)'. Sanskrit chattra, a parasol on top of a venerated Indian stupa buried with Buddha's sarira, became the symbol of majesty. The Indian stupa was transformed into a pagoda in China, and the highlighted parasol on the summit was transliterated into chaldara(刹多羅), an abbreviation for chal (刹), and finally designated the whole pagoda(塔). Sachal consists with lying low monastery and high-rise pagoda. Tapsa(塔寺), an archaic word of temple, is exactly the same as sachal, because chal means tap, pagoda. However, during the 7th century a Buddhist monk erroneously double-transliterated the Sanskrit 'kshetra,' meaning of land, into the same word as chal, even despite phonetic disaccord. Thereafter, sutra translators followed and copied the error for long centuries. It was the Japanese pioneer scholars that worsen the situation 100 years ago, to publish Sanskrit dictionaries with the errors insisting on phonetic transliteration, though pronunciation of 'kshe-' which is quite different from 'cha-.' Thereafter, upcoming scholars followed their fallacy without any verification. Fallacy of chal, meaning of land, dominates Buddhist community broadly, falling into conviction of collective fixed dogma in East Asia up to now. In the Buddhist community, it is the most important matter to recognize that the same language has become to refer completely different objects due to translation errors. As a research method, searching for corresponding Sanskrit words in translated sutras and dictionaries of Buddhism is predominant. Then, after analyzing the authenticity, the fallacy toward the truth will be corrected.

We synthesized a new photo-crosslinkable polymer (polyimide (PI)-chalcone-biphenyl (BP)) and liquid crystal (LC) aligning capabilities for nematic (N) LC with obliquely polarized UV exposure on a photo-crosslinkable polymer were studied. The high pretilt angle in NLC was obtained by polarized UV exposure on a PI-Chal-BP surface for 3 min. The high pretilt angle generated in NLC is attributed to the biphenyl moieties and the photo-dimerized chalclone group of a photopolymer. Also, good thermal stability of a PI-Chal-BP were obtained by thermogravimetric analysis (TGA) measurement until 450$^{\circ}C$. Finally, good voltage-transmittance curves and response time were observed by UV exposure on a PI-Chal-BP surface for 3min.

Immature embryos of 3 cultivars (Du Me Chal, Mi Baek Chal, Heug Jeom Chal) and 5 genotypes (HW1, KL103, HW3, HW4, KW7) were cultured on medium containing MS salts, Eriksson's vitamins, 1 mg/L 2,4-dichlorophenoxyacetic acid, 25 mM proline, 100 mg/L casamino acid, 3 mM MES, 1.7 mg/L $AgNO_3$ and 20 g/L sucrose (SIM). Frequency of somatic embryo formation on explant of immature embryos showed in HW1 (45.20%), KL103 (5.75%), HW3 (37.20%), HW4 (30.10%), KW70 (55.20%), Mi Baek Chal (18.74%), Heug Jeom Chal (22.41%), Du Me Chal (36.72%) and Hi II type (<10%), respectively. Yellowish friable embryogenic callus (YFEC) such as type II callus of Hi II genotype only produced from the HW3 and Heug Jeom Chal, whereas other cultivars and genotypes were directly formed somatic embryos with late-embryonic stages or expanded yellowish compact somatic embryo with morphological abnormality. The yellowish friable embryogenic callus (YFEC) could be proliferated on the same medium, which were maintained embryogenic capacity for 6 months over. Upon transfer to first regeneration and second regeneration medium, somatic embryos converted to plantlets at a frequency of approximately 100%. However, the expanded somatic embryos with abnormal morphology were slowly proliferated when subcultured on the same medium, and some of them were degenerated or converted to plantlets at a frequency of approximately 25%. Accordingly, The Heug Jeom Chal and HW3 genotype will be further used for development of high frequency transformation system in domestic maize germplasm.

A new single glutinous maize hybrid "Huin Chal 1" was developed at the Genetics and Breeding Lab., Dept. of Agron., College of Agriculture, Chungnam National University. Parents for the hybrid were all derived from Korean indigenous maize lines which were collected in 1980s. One of the parental inbred lines was originated from Bosung, Chonnam province and other inbred line was from Jewon, Chungbuk province. Both inbreds were developed by ear-to-row selection method through selling and named as Bosung and Jewon, respectively. Performace tests for the hybrid which was produced between Bosung and Jewon have been conducted five times including one test at Crop Experiment Station, Rural Development Administration. From the previous performance tests, the hybrid was recognized as high yielding hybrid with good agronomic characteristics and we named the hybrid as Huin Chal 1., and hereby we report the agronomic characters of the newly developed hybrid.

To achieve the aim of science education, it is known that warious teaching, and learning materials should have to be used. As a sub-textbook for primary science education, 'Sil Hum-Kwan Chal (Experiment and Observation), teaching and learing material are developed and using now in science. This material have following characteristics; (a) Soruce-book contains reading materials for additional information, various pictures to enririch the science concepts, and supplementary and enrichment activities. (b) Work-book consists of the detailed procedures of activities of experiments presented in the textbook, student can record the experimental procedures and results. (c) Operational manuals provide operation techniques for experimental equipments which are used in science class. In this study the using status are surveyed for the 3rd grade of primary school, and based on this survey the improvement plan are discussed in view of design, quantity and utility, of sub-textbook.
