In this study, we investigated and compared some chemical properties of Korean natural honeys and sugar-fed honeys for their quality characteristics. The natural honey samples were monofloral from chestnut and acacia flowers, and the sugar-fed honey samples were collected from honeybees feeding on sugar cane and sugar beet. The chemical properties of the honey samples, such as moisture, total protein, total lipids, ash, carbohydrate, minerals, vitamins, and free amino acids were determined. The moisture content was $18.5{\pm}0.9%$ in natural acacia honey, $17.2{\pm}0.9%$ in natural chestnut honey, $19.6{\pm}0.9%$ in sugar cane-fed honey, and $24.8{\pm}%$ in sugar beet-fed honey. The total protein and ash contents were the highest in natural chestnut honey. Maltose and sucrose were not detected in natural honeys but were detected at 2~7% in sugar-fed honeys. The vitamin, mineral, and free amino acids contents of natural honeys were higher than sugar-fed honeys. The natural chestnut honey is the highest in honeys. These results confirmed that the quality of natural honey was better than that of sugar-fed honey. Also, the vitamin, mineral, and free amino acids contents are potential characteristics for distinguishing between natural and sugar-fed honeys.

Two experiments were conducted to study the use of urea-treated rice straw (UTRS) and whole sugar cane (WSC) crop as roughage sources for dairy cattle during the dry season. Experiment I, four rumen-fistulated dairy crossbred steers were assigned to receive roughage treatments according to a $4{\times}4$ Latin square design: $T_1=urea-treated$ (5%) rice straw, $T_2=UTRS$ and WSC at 75:25% DM, $T_3=UTRS$ and WSC at 25:75% DM, and $T_4=WSC$. Experiment II, three rumen fistulated, late lactating multiparous Holstein-Friesian crossbreds were randomly allotted to a $3{\times}3$ Latin square design to receive three types of roughages; $T_1=WSC$, $T_2=UTRS$, $T_3=WSC+UTRS$ at 50:50% DM. It was found that combination of UTRS and WSC at 75:25 ratio significantly increased DM intake while intake of WSC alone was lowest. Moreover, inclusion of UTRS into WSC enhanced digestibilites (Exp. I). In Exp. II, combination of UTRS with WSC at 50:50 ratio (DM) enhanced DM intake (kg/d) (p<0.05) and especially milk yield, milk fat and protein percentages. The findings suggest the combined use of WSC and UTRS improved the feeding values of these roughages for dairy cattle during the dry season.

사탕수수 찌거기를 여름느타리에 의해 발효한 후 부산물의 추출물로부터 생물학적 활성을 조사하기 위하여, 항종양성, 콩에 있어서의 glyceollin 유도성 및 완두에 있어서의 줄기 성장성을 관찰하였다. 알콜추출분획 및 DMSO분획물은 자실체 추출분획보다는 약했지만 매우 좋은 항종양성을 나타내었다. 콩의 자엽실험에서는 모든 추출물이 식물체로 하여금 병원성 감염을 방지할 수 있는 glyceollin 유도성을 갖고 있었다. 또한 IAA 유도 줄기성장 실험에서는 양성반응을 보인 모든 실험군에서 IAA와 추출물간의 유도 상승효과가 있는 것으로 나타났다.

The sole use of the glucanhydrolase (exhibiting both dextranase and amylase activities) from Lipomyces starkeyi hydrolyzed the soluble polysaccharides in sugar syrup more efficiently than a mixed treatment using both commercial dextranase and amylase. The glucanhydrolase treatment of stale sugar cane juice resulted in a yield of square, light-colored sugar crystals.

NP-완전인 상자 포장 문제의 일종인 사탕수수 설탕 생산 문제에 대해, Gu$\acute{e}$ret et al.은 $O(m^4)$ 수행 복잡도의 선형계획법으로 해를 얻고자 하였다. 반면에, 본 논문에서는 사탕수수 설탕 생산 문제는 다항시간으로 해를 찾아가는 규칙이 존재한다는 가정하에, 최대 손실량을 가진 로트를 우선 생산하는 탐욕 규칙인 O(mlogm)의 다항시간 복잡도로 해를 구할 수 있는 알고리즘을 제안하였다. 제안된 방법은 설탕 함유량 손실 기울기를 내림차순으로 정렬한 후, 해당 슬롯 생산능력의 로트들을 선택하는 방법과 해당 슬롯에서 수명을 다하는 로트들과 마지막으로 선택된 로트들과 교환하는 방법을 적용하였다. 실험 결과, 제안된 알고리즘은 사탕수수 설탕 생산 문제에 대해 선형계획법의 $O(m^4)$를 O(mlogm) 으로 단축시키면서도 보다 좋은 결과를 얻었다.

The annual income (gross margin) in 1989/90 of a sample of 274 farmers in seven milk cooperatives was analyzed in the sugar cane, cassava, and horticulture areas in East Java. On average dairying contributed 42%, crops 29% and off-farm revenue 29%. Dairy income was highest in the cassava area, where it compensated for the low crop income, and lowest in the sugar cane area. Farm area and average milk yield per day per cow correlated positively with farmer's income, whereas crop income increase significantly with farm area and with the number of cows. The level of total cost per cow had a negative impact on dairy and with the number of cows. The level of total cost per cow had a negative impact on dairy and on total income. Government officials and other professionals engaged in dairying had a significantly higher total income than those with their main occupation in dairying, cropping or working as farm labourers. Uneducated farmers obtained a significantly larger income through crops, whereas farmers with tertiary education obtained more income through off-farm work, This study suggests that more attention must be paid to the actual use of labour and the improvement of the dairy output/cost ratio.

Thirty mature pregnant ewes of the Phan Rang breed with an initial live weight of 30 to 45 kg were used to compare the effects of three different diets in late pregnancy on ewe and lamb performance. All diets contained 20% of whole sugar cane, 16% rice bran, 26% cassava root and 6% molasses urea block. The remaining 32% of dry matter consisted of Jackfruit (JF diet), 16% each of Jackfruit and Cassava foliage (JF+CS diet) or Jackfruit and Flemingia foliage (JF+FM diet). The diets were fed at 3.5% of actual BW of the individual animal. The foliages were offered at 120% of the amount decided in the diets of the requirements. The JF+CS diet resulted in significantly higher feed intake than the JF diet, and also a higher feed intake than the JF+FM diet, but this difference was not significant. The ewe weight changes during the last 8 weeks of pregnancy, or from start to 24 h after lambing, were significantly different. The highest weight gain was obtained from the ewes fed the JF+CS diet. Diets had no effect on weight changes of ewes during 3 weeks after lambing but a significant effect on the litter birth weight, with the JF+CS diet giving the highest litter birth weight. There was, however, no effect on the litter weight at 21 days or litter growth rate from birth to 21 days due to the experimental diets.

269 yeast strains were isolated from water samples collected from different sites in Minia governorate. These included 126 strains from fresh water, 108 strains from sewage and 35 strains from wastewater from sugar-cane factory. On the basis of 23 different physiological and morphological merkmals, the isolated strains were assigned to 16 species belonging to 11 genera. Total yeast cell counts as well as spectra of yeast species were highly variable in tested water. Total yeast cell counts ranged between $3.0{\times}10^3/l\;and\;1.8{\times}10^6/l$ for fresh water, $3.0{\times}10^4/l\;and\;3.0{\times}10^7/l$ for sewage and $1.5{\times}10^6/l\;and\;2.6{\times}10^7/l$ for wastewater from sugarcane factory. Debaryomyces hansenii, Rhodotorula mucilaginosa and Torulaspora delbrueckii were the dominant species in fresh water, whereas Debaryomyces hansenii, Thrichosporon beigelii, Rhodoforula mucilaginosa and Kluyveromyces marxianus were the dominant species in sewage and Saccharomyces cerevisiae, Kluyveromyces marxianus and Trichosporon beigelii were the dominant species in wastewater from sugar-cane factory. Yeast human pathogens, Trichosporon beigelii, Rhodotorula mucilaginosa and Candida albicans were encountered in water samples indicating that water in El-Minia governorate is also polluted by some pathogenic yeasts.

Common reed (Fragmites australis), a local invasive grass, was investigated as a possible feedstock for the production of activated carbon. Dried crushed stems were subjected to impregnation with phosphoric acid (30, 40 and 50%) followed by pyrolysis at $400{\sim}500^{\circ}C$ with final washing and drying. Obtained carbons were characterized by determining: carbon yield, ash content, slurry pH, textural properties and capacity to remove color bodies from factory-grade sugar liquor. Produced carbons possessed surface area up to 700 $m^2/g$, total pore volumes up to 0.37 $cm^3/g$, and proved to be microporous in nature. Decolorization of hot sugar liquor at $80^{\circ}C$ showed degrees of color removal of 60 up to 77% from initial color of 1100~1300 ICU, at a carbon dose of 1.0 g/100 ml liquor. No correlation seems to hold between synthesis conditions and % R but depends on the degree of microporosity. A commercial activated carbon N showed a comparative better color removal capacity of 91%. Common reed proved to be a viable carbon precursor for production of good adsorbing carbon suitable for decolorization in the sugar industry, as well as in other environmental remediation processes.
