        KORAD (Korea Radioactive Waste Agency, http://www.korad.or.kr) has stored slightly contaminated ascon (asphalt coated concrete mixture) that was introduced to Gyeongju repository about a decade ago waiting for a final disposal. It is believed to be mainly contaminated by radioisotope 137Cs due to impurities introduced from the outside during the ascon manufacturing process. We studied characteristics of the radioactive waste to see whether this material would be proper enough to be disposed in Gyeongju LILW repository or be other ways to reduce the disposal volume including self-disposal before its final disposal otherwise. KORAD looked into the properness of characteristics of ascon in terms of WAC (Waste Acceptance Criteria) documented by KORAD that includes general chemical and physical properties of asphalt, density, size of grains, content of organic material and possibility of existence of chelate materials that qualitatively limited to be disposed by the criteria. And other associated characteristics such as gas generation and bio degradation were also investigated. Based on the data obtained from the study, we proposed various plausible solutions in associated with operational and disposal safety and economic view points. This study will be used for KORAD’s decision on how to control and safely dispose the spent ascon within a reasonable time period. And also those experiences may be applied for other LILW issues that require treatment or conditioning of radioactive wastes in the future.

        To breed a new Korean Pleurotus eryngii cultivar with high quality and yield, single crosses between 24×46 and KNR2539 were performed, and a new cultivar, 6×13, was selected based on the days to harvest (14.6 days), quality (7.2), and yield (85.9 g/850 cc bottle). The strain was named Aeryni 5 and cultivated on a large scale at the mushroom farms to compare with Keuneutari 2ho. The yield of Aeryni 5 (82.2 g) was 122.7% of Keuneutari 2ho, and the quality of the new cultivar was 7.7 while reference cultivar was 6.3. The yield and quality of the two cultivars were statistically different. The lightness of the pileus of Aeryni 5 (61.7) was greater than that of Keuneutari 2ho by 3.4 points; thus, the pileus of Aeryni 5 looked brighter. PCR with URP2 was used to discriminate between Aeryni 5 and Kenneutari 2ho.

        The use of agricultural by-products as alternative nutrient sources in crop production had gained popularity in order to reducing the rate of chemical fertilizer application in the field. This study was conducted to determine whether the application of rice milling by-products treated with yeast inoculants could substitute, or reduce the rate of chemical fertilizer application. The results of agronomic measurements showed that the effect of incorporated materials was not immediate, as compared to 100% chemical fertilizer application. However, grain yield and quality was either the same or greater than 100% chemical fertilizer application. It was found out that expanded rice hull (treated with yeast or not) could reduce the rate of applying chemical fertilizers by half. Also, yeast treatment was only favorable only to expanded rice hull and not with rice bran, and was already found to be a potential material in reducing chemical fertilizer application in rice production.

        Lee, Sangdae. 1998. Tense and Aspect in English. Studies in Modern Grammatical theories 12, 187-214. This paper is to allow for a unified analysis of tense, and aspect, not committed to a particular theoretical framework but to a comprehensive descriptive syntax. Aspect and tense are both concerned with temporal reference, and considering that tense sometimes may imply aspectual meaning, it is difficult to distinguish between tense and aspect. The English aspect, however, deserves an independent grammatical category as it has syntactic devices to express various aspectual meanings related to non-dietic time in aspect. Aspectual meanings vary according to the distinction of count terms and mass terms, the interaction of the event quantification with the argument quantification like the subject and object, and the interaction of the event quantification with the adjunctive quantification. Therefore, to describe the tense and aspect, we should consider not the verb alone but the relations between the other grammatical categories, including subject, object, and ever adverb. Relevant contexts can reveal the relevant situations which tense and aspect represent.
