This study was performed to investigate the nutritive values of white panicled rice (Oryza sativa L., WPR) silage manufactured with WPR grown in reclaimed paddy field of Bigumdo of Korea in 2011. The WPR used in this study were collected in 1,000 ha of reclaimed paddy field of Bigumdo and was harvested at dough stage and ensiled. The yield of whole crop rice (WCR) grown in region received the most severe damage (MSD) was lower as about 800 kg/ha as than that in region of normal growth (NG). The content of crude protein and total digestible nutrient in WCR of MSD slightly increased, as compared to that in WCR of NG, but the contents of acid detergent fiber and neutral detergent fiber significantly decreased (p<0.05). The pH in WCR silage of MSD and NG ranged from 4.5 to 5.0 and pH decreased by the inoculation of lactic bacteria (p<0.05). The content of lactic acid in WCR silage of MSD and NG increased by the inoculation of lactic bacteria (p<0.05), but the content of acetic acid and butyric acid decreased (p<0.05). Flieg's score in WCR silage of MSD and NG inoculated lactic bacteria increased from 2 to 3 grade, as comparing to non-inoculation of lactic bacteria. Therefore, this study suggests that WPR can be utilized as forage.

소아들의 음성장애의 대부분은 음성과 기능에 의한 성대의 오용 및 남용으로부터 기인한다. 그러나 음성장애에 대한 인식의 부족으로 인하여 소아의 음성장애 발견율은 극히 낮은 수준에 머므르고 있다. 치료에 있어서도 행동의 통제가 그다지 쉽지 않기 때문에 많은 어려움이 따른다. 본 연구는 소아의 음성장애의 발생경위와 문제의 설명과 차팅에 의한 남용의 감소에 초점을 둔 치료사례이다. 5세 아동의 심한 음성장애로 의뢰되어졌다. 음성증후는 목쉰소리, 기식화된 소리, 일시적인 발성일탈(phonation break) 등이 두드러졌다. 이비인후과 전문의의 스트로보스코프(stroboscope) 검진결과 초기 양측성 성대결절이 성대 앞쪽으로부터 1/3 지점에서 발견되었으며 비지피치(Visi-Pitch)로 측정된 퍼터베이션(perturbation 수치가 16.8이었다. 사례사 조사 과정에서 아동이 활동적이며 자주 고함을 지르고 자동차놀이를 주로하며 많은 시간을 보낸다는 것이 밝혀졌다. 중재 프로그램은 우선 문제를 설명하고 인식시키는 것과 고함을 지르거나 자동차놀이를 하면서 자동차 소음을 흉내내는 등의 음성남용 회수를 감소시키는 것에 초점을 두었다 17회의 치료로 성대결절이 감소되었고 퍼터베이션은 3.8로 저하되었으며 아동 스스로 음성남용을 통제할 수 있다는 임상적 판단하에 치료를 종결하였다. 1개월 후 추후 검사에서 남용적인 습관이 여전히 나타나지 않았으며 음성상태도 양호하였다. 소아 음성장애의 치료는 소아가 이해할 수 있는 용어로 문제의 인식을 확실히 시키고 행동을 체계적으로 통제할 수 있는 치료프로그램을 실행시키는 임상가의 자질이 대단히 중요하다. 그러나 그에 못지 않게, 많은 시간을 아동과 함께 보내는 부모나 교사의 협력이 치료의 성패를 좌우할 수 있다.조구와 처리구간에 차이가 없었다. 그러나 유지방 함량의 경우 대조구가 3.22%, 처리구가 3.37%로 처리구가 0.15% point 증가했으나 유의차는 없었다.

To investigate the effects of nitrogen(N) fertilization levels on the dry matter(DM) yield, nutrition yield, and N efficiency of forages in mixed sward of alfalfa-grasses, a field experiment arranged by randomized complete block design with five treatments(0, 70, 140, 210 and 280kg N/ha) was conducted at Livestock Experiment Station in Suwon, September, 1990 to February, 1993. During two years, average DM yields of forage increased as N fertilization level was increased, but no significant difference was found between DM 10,266kg of N 210kgha and DM 10,845kg of N 280kgha. Crude protein and energy productivity of forages increased as N fertilization level was increased, and the increasing degree was highest between N 140kg and 210kg/ha fertilization. With increasing N fertilization, mineral contents tended to decrease in P and K/Ca+ Mg equivalent ratios, to increase in Mg, but not to be regular in the other elements. Efficiency of N was highest at N 210kg/ha fertilization, which produced DM 21.6kg, net energy lactation 129.3 MJ, starch equivalent 12.3kStE and total digestible nutrients 14.5kg per Ikg N.

Silage yield Potential and some agronomic characteristics of Korean improved and introduced corn hybrids from the United States were tested for five year in Gyeongsan, Gyeongsangbug-do and for one year in Hongcheon, Gangwon-do. 1. At 20 days after emergence, plant height and dry matter of hybrids were different, while the early growth of the hybrids was not correlated to the culm length and silage yield. 2. In Cyeongsan, silage yield potential of Suwon19 was relatively high, while most susceptible to rice black-streaked dwarf virus (RBSDV) disease and leaf senescence at harvest time. In contrast, silage yield potential and resistance to RBSDV of Cwanganok were moderate, while susceptible to leaf senescence at harvest. Generally, Suwon19 showed similar or higher yield than most introduced hybrids, while some introduced hybrids showed lower silage yield than Korean improved hybrids. Most introduced hybrids were more resistant to RBSDV and leaf senescence at harvest time compared to Korean improved hybrids. 3. In Hongcheon, silage yield of three Korean improved hybrids were lower than that of NC+5514 and DK729, while similar or higher than other introduced hybrids. af senescence of all Korean hybrids was severer compared to introduced hybrids.

This study was carried out to investigate the effect of harvest stage of rape on nutritive values and quality of round baled rape silage in field of forage crops of Department of Animal Resources Development, National Institute of Animal Science, RDA. Rape was harvested at three different growth stages (flowering, milk and dough stage) and ensiled at each harvest stages. The content of moisture of rape increased with delayed harvest maturity. However, the content of moisture of rape was controlled by pre-wilting (24 hr. and 48 hr). The content of moisture in dough stage was similar to that of haylage. The content of crude protein in round baled rape silage increased with delayed harvest maturity, but the contents of acid detergent fiber, neutral detergent fiber and total digestible nutrient decreased. The pH in all rape silage ranged from 3.8 to 4.4 at three different harvest stages, and pH in dough stage was higher than that of flowering and milk stages (p<0.05). The content of lactic acid of all rape silage increased with delayed harvest maturity (p<0.05), but the content of acetic acid decreased (p<0.05). And then, flieg's score revealed that there was an increase in order; flowering stage (100) = milk stage (100) > ripen stage (88).
