The effect of various moisture contents of fresh forage on the change in nitrogen (N) fractions, in vitro ruminal N degradability, and the subsequent N utilization of silage in sheep were evaluated. Orchardgrass (Dactylis glomerata L.) with high (HM, 76%), medium (MM, 65%) and low (LM, 40%) moisture contents were ensiled into silos of 120 L capacity for 120 days. A nitrogen balance trial was conducted using a 4${\times}$4 Latin square design consisting of four dietary treatments (i.e. fresh forage, HM, MM and LM silages) and four wethers. With respect to N fractions, fraction 1 (buffer solution soluble N), fraction 2 (buffer solution insoluble N-neutral detergent insoluble N), fraction 3 (neutral detergent insoluble N-acid detergent insoluble N), and fraction 4 (acid detergent insoluble N) were determined. The proportion of fraction 1 in silages tended to decrease, while the in vitro ruminal degradability of insoluble N increased (p<0.05) with lower moisture contents at ensiling. Consequently, nitrogen utilization in sheep tended to improve as the moisture content of ensiled grass was decreased, with a negative correlation (p<0.01) between urinary N and the in vitro ruminal degradability of insoluble N. The averaged N retentions for HM, MM, and LM silage treatments were 59, 73 and 79% of that for fresh forage, respectively.

This study examined the effects of various oils used in the preparation of goami baked Yackwa dough on the quality characteristics of goami baked Yackwa. To determine the optimal amount of oil for goami powder Yackwa dough, the hardness and moisture contents of both the flour and goami powder dough were measured. Dough hardness was the highest in flour Yackwa while moisture contents was the highest in goami Yackwa. Baked weight and dip syrup weight were heavier in flour. Hardness, a-values, and b-values were the highest in flour Yackwa, whereas moisture contents and L-values was the highest in goami Yackwa. In a sensory evaluation, overall preference was the highest for goami Yackwa and flour Yackwa made with 10% oil.

This study determined the effects of the dietary moisture level and feeding rate on the growth and gastric evacuation of young olive flounder. Four experimental diets with different moisture levels (9%, 21%, 30%, and 40%) were prepared through the addition of water to the commercial extruded pellet. Three replicate groups of fish (initial weight: $106{\pm}1.4\;g$) were fed diets containing 9%, 21%, 30%, and 40% moisture to satiation or a moisture level of 9% and 30% at a restricted feeding rate (95% of satiation) for 15 weeks. The mean water temperature was $22{\pm}1.6^{\circ}C$ during the feeding trial. Gastric evacuation rates were determined post-feeding. The dietary moisture levels did not significantly affect weight gain, but the weight of the fish receiving 9% and 30% moisture diets to 95% satiation were significantly lower than those of the fish fed 9-40% moisture diets to 100% satiation (P<0.05). The feed efficiency, protein efficiency ratio, viscerosomatic index, and survival were not significantly affected by the dietary moisture levels and feeding rates. The daily feed intake of the fish fed to 100% satiation did not significantly differ among the treatment groups. The stomach contents that peaked within 3 h of feeding gradually decreased, and the stomachs of fish were completely evacuated within 18 h. The contents of the intestine peaked at 3-12 h post-feeding, and then declined with the intestine being mostly evacuated at 30 h. The moisture of the stomach contents reached approximately 70% within 3 h post-feeding and gradually increased to approximately 75% within 12 h. No considerable differences were observed in the gastric evacuation and moisture levels of the stomach contents in the fish fed the different diets. The results of this study suggest that the gastric evacuation of olive flounder was not affected by the dietary moisture level and that the addition of water into the diet displayed no beneficial effects on the growth of young olive flounder.

Moisture measurements of s intering materials were performed using the simulator which can simulate various conditions taking place at the belt-conveyor of sintering process. The moisture sensor used in this experiment is NIR moisture meter(JE-330, KETT Electric Lab.). Using the simulator, we measured the moisture contents of sintering materials at different conditions. We found that the moisture content decreased as the rotation speed increased and the size of the sintering materials became smaller.

분리대두단백의 조직화에 대한 스크류 회전속도와 원료 수분함량의 영향을 조사하였다. 수분함량이 증가함에 따라 토출구온도는 감소하였으며 210rpm에서 가장 높은 온도를 나타내었다. 수용성 질소지수는 수분함량이 증가할수록 감소하였으며 고속보다는 저속에서 감소폭이 컸다. 조직잔사지수는 낮은 수분함량과 고속 rpm에서 높게 나타났으며 조직감의 강도는 이와 반대의 경향이었다. 또한 원료의 수분함량이 증가할수록 최종 압출성형물의 수분함량이 증가하였고 고속 rpm일수록 낮은 수분함량을 나타내었다. 밀도의 경향도 이와 일치하였다. 재흡수력의 경우는 수분함량 30%에서 최고치를 나타내었으며 고속 rpm에서 증가하였다. 복원전의 명초는 복원 후 보다 높은 수치를 보였고 고속회전일 수록 명도가 밝아졌다. 성상에 있어서도 저수분, 고속 rpm에서 높은 명도와 높은 정화도가 관찰되었다. 분산분석을 통해서 스크류 회전속도보다 원료의 수분함량이 조직화 성질을 나타내는 각 지표에 더 깊은 영향을 주는 것으로 확인되었다.

Two experiments were conducted to investigate the effects of dietary moisture content on the growth and gastrointestinal evacuation of sub-adult olive flounder (Paralichthys olivaceus) in the summer and winter seasons. In the first experiment, three experimental diets containing different moisture levels (7%, 15%) and additives were prepared by adding water and commercial additives (1% nutrients, 1% digestives) to commercial extruded pellets. Fish (initial weight: $332{\pm}9.2$ g) were distributed randomly into six 3000 L tanks (25 fish/tank) in a flow-through tank system. Two replicate groups of fish were fed the experimental diets to satiation for 14 weeks during the summer season ($21.4{\pm}2.5^{\circ}C$). Survival, weight gain, feed efficiency, and daily feed intake did not differ significantly among groups. In the second experiment, two experimental diets containing different moisture levels (8%, 23%) were prepared by adding water to commercial extruded pellets. Fish (initial weight: $646{\pm}6.7$ g) were randomly distributed into six 3000 L tanks (20 fish/tank) in a flow-through tank system. Three replicate groups of fish were fed the experimental diets to satiation for 19 weeks during the winter season ($12.2{\pm}1.2^{\circ}C$). Weight gain, feed efficiency, and daily feed intake did not differ significantly among groups. Gastrointestinal evacuation rates were determined after the end of the winter feeding trials. The stomach contents of fish fed diets containing different moisture levels peaked within 3 h after feeding and then decreased gradually over 40 h to approach pre-feeding levels. Intestinal contents began to accumulate 3 h after feeding and reached a maximum at 32 h, then declined until nearly complete evacuation around 56 h. The stomach contents reached moisture levels of approximately 70% within 3 h after feeding and then increased gradually. No considerable difference in moisture levels was observed in the stomach contents of fish fed diets with different moisture contents. The results of this study suggest that the gastric evacuation of sub-adult olive flounder was not affected by dietary moisture level and the addition of water to the diet had no beneficial effect on the growth of sub-adult olive flounder in the summer and winter seasons.

1. 수확시기에 따른 도정수율은 메벼의 적기수확시기보다 5일정도 늦게 수확하는 것이 높았으며 품종에 따라서는 보석찰벼와 해평찰벼가 도정수율이 높았다. 2. 찹쌀의 특징인 불투명한 유백색은 수분함량 14.0%이상부터 점차 소실되기 시작하여 15.0%대에 마치 멥쌀이 섞인 것처럼 보이다가 16.0%이상에 도달될 경우는 거의 대부분이 멥쌀과 같은 외관을 나타냈다. 3. 수분 증가에 따른 찹쌀의 유백색 소실은 조기에 수확된 벼에서 더 민감하게 나타나기 때문에 가능한 수확시기를 적기 이후로 정하는 것이 건조효율이나 찹쌀 수율 측면에서 더 유리하다고 판단된다. 4. 찹쌀 고유의 유백색 발현을 최대로 하기 위해서는 찰벼 건조수분의 critical point은 13.5%이하였다.

콘크리트가 화재에 노출되면 콘크리트 표면에서의 수분뿐만 아니라 콘크리트 내부에서의 수분도 수분의 평형 및 전달조건에 의하여 증발이 발생된다. 수분의 평형조건은 재료의 자기이력거동으로 표현되는 물의 증발에 대한 수착등온선 관계로 설명된다. 본 논문은 화재시 콘크리트 내부의 수분변화를 예측하고자 하는 것으로 부재 내부의 임의의 위치에서의 상대함수율을 산정하기 위하여 유한요소방식을 적용하였다. 또한 고온에서 콘크리트의 수분확산 특성치에 대해서도 모델식을 제시하였다. 이러한 해석기법의 정확성을 검증하기 위하여 실험데이터와 비교하였으며, 그 결과 수분증발로 인하여 수분이 감소되는 효과를 포함한 전반적인 부재 내부의 수분이동현상이 실제 실험데이터와 거의 유사하게 나타나는 것으로 확인되었다.

The fragility, which express the fineness index, increased linearly with the moisture content for various tobacco shreds and showed a high correlation to the moisture content. Then, fineness index (FIs) at reference moisture content(l2.5%) was obtained by following equation. FIs=FIm+A(12.5-Mm) A" denote the gradient of simple linear regression equation between the fineness index and moisture content. FIm; the fineness index measured at the standard moisture content(12.5%). The characteristics of fragility concerning with some kinds of tobacco raw materials, stalk position, moisture content and storaged time were investigated. The following results were obtained. 1. The moisture content range of less fragile of tobacco raw material was from 16% to 20%. whereas the rolled process sheet tobacco was from 12% to 16%. 2. The Bright yellow and the paper process sheet tobacco were less fragile than that of the other tobacco raw materials. 3. The leaves were more distant from middle stalk position, and its become more fragile. 4. Physical properties of the storaged tobacco leaves were determined as a function of each storageunction of each storage time. The long-term storaged leaves(more than 3 years) were slightly lighter weight, more fragility and lower equilbrium moisture content than thos of the mid-term storaged leaves.(less than 3 years). 5. Contents of chemical component of the storaged leaves were determined every storage time. The long-term storaged leaves were slightly lower content of nicotine and chlorine than those of mid-term storaged leaves, but contents of crude fiber, total ash and calcium were increased significantly.
