A new barley (Hordeum vulgare L.) cultivar 'Mihan' having ruminant-palatable semi-smooth awn and good silage quality was developed at National Institute of Crop Science(NICS), RDA in 2016. This cultivar was derived from a cross of the 'SB00T2064' and 'Suwon385' in 2001. And its promising line showed high yielding through the preliminary yield trials(PYT) and advanced yield trials (AYT) in Iksan from 2012 to 2013. It was designated as the 'Iksan487'. 'Iksan487' was conducted to regional yield trials (RYT) in one upland field and five paddy fields around Korea for three years from 2014 to 2016. And it was released as the name of 'Mihan'. It has growth habit of IV, erect plant type, green leaf and semi-smooth awn. Its heading date was April 23 in the paddy field and maturing date was May 24. Plant height of 'Mihan' was 96cm. Mihan's spikes per $m^2$ was 665. It has better winter hardiness and resistance to BaYMV (Barley Yellow Mosaic Virus) than that of barley cultivar 'Youngyang'. The average dry matter of 'Mihan' was about $10.9ton\;ha^{-1}$ in paddy field. And average feed quality of 'Mihan' was 10.3% of crude protein content, 26.1% of ADF (Acid Detergent Fiber), 46.9 % of NDF (Neutral Detergent Fiber) and 68.2% of TDN (Total Digestible Nutrients). 'Mihan' had grade I of silage quality. This cultivar would be suitable for the area above the daily minimum average temperature of $-8^{\circ}C$ in January in Korean peninsula.

This study aimed to determine the optimal harvesting time for wheat to make grain silage, in Honam region of Korea. We harvested wheat grain every third day from 30 to 42 days after heading (DAH). The moisture content decreased from 61.6% at 30 DAH to 42.8% at 42 DAH. Yield of wheat grain significantly increased from 30 to 42 DAH (p< 0.05). Yield at 39 DAH (3.46T/ha) was not significantly different from that at 42 DAH (p< 0.05). With respect to the feed value of wheat grain silage, the amount of crude protein, crude fiber, and crude ash was different by harvesting time (p< 0.05). However, the amount of total digestible nutrients (TDN) from 30 and 42 DAH was not significantly different. The pH of wheat grain silage from 30 to 42 DAH was between 3.8 and 4.5 and it was stable until 39 DAH (p< 0.05). The lactic acid content of wheat grain silage from 30 to 42 DAH decreased from 3.08% to 1.10%. With respect to moisture content, yield, feed value, and fermentation, the optimal harvesting time for wheat grain silage was 39 DAH.

This study was conducted to observe the influence of chemical pesticides and environmentally friendly agricultural materials (EFAMs) used in tomato cultivation on the pathogenicity of the entomopathogenic fungus, Beauveria bassiana. B. bassiana mycelium didn't grow on PDA media containing 13 fungicides including chlorothalonil and colonies were not formed on PDA media containing 12 fungicides. B. bassiana mycelium grew and colonies were formed on all PDA media containing insecticides and EFAMs, but mycelial growth and colony formation on most PDA media were significantly inhibited compared to the control. The insecticidal activity of B. bassiana against Trialeurodes vaporariorum was decreased when fungicides (polyoxin B, mandipropamid) and EFAMs containing sulfur were added, but insecticides (pyridaben, dinotefuran) and EFAMs originated from plant extracts did not have any influence on the insecticidal activity of B. bassiana. The pathogenicity of a mixture of B. bassiana and polyoxin B against T. vaporariorum was lower than that of B. bassiana alone under greenhouse conditions. 토마토 재배에 사용되는 농자재를 이용하여 곤충 병원성 곰팡이인 Beauveria bassiana의 병원성에 끼치는 영향을 조사하였다. Chlorothalonil 등 13종의 살균제 첨가 배지에서는 B. bassiana 균사가 전혀 생장하지 못하였고 chlorothalonil 등 12종의 살균제 첨가 배지에서 균총이 형성되지 않았다. 살충제와 친환경자재를 첨가한 모든 배지에서 균사가 생장하고 포자가 형성되었지만 대부분 배지에서 무처리와 비교했을 때 유의차를 보였다. 온실가루이에 대한 살충력은 B. bassiana 단독처리일 때보다 화학살균제(polyoxin B, mandipropamid)와 친환경농자재(sulfur) 혼합시 떨어졌으며 화학살충제(pyridaben, dinotefuran)와 식물추출물 유래 친환경농자재(pyrethrum) 혼합시에는 유의차가 없었으며 온실에서 살균제인 polyoxin B의 혼합으로 온실가루이에 대한 B. bassiana의 감염력이 떨어지는 것을 확인하였다.

Disperse dyes derived from heterocyclic compounds such as pyridone, diaminopyridine, carbazole, and 2-phenylindole, have been known to possess high light fastness. Four heterocyclic azo disperse dyes were synthesized by using three diaminopyridines and 2-phenylindole as coulping components and their dyeing and fastness properties were compared with an aminoazobenzene disperse dye. The wavelengths of maximum absorption of the synthesized heterocyclic dyes were in the range of 508-528 nm. The molar extinction coefficients of dyes having diaminopyridine were higher than that of an aminoazobenzene disperse dye. The dyes derived from aminopyridine having phenyl group exhibited poor to moderate build-up compared to the aminoazobenzene dye. Wash, light, heat and rubbing fastnesses of heterocyclic azo disperse dyes were good to excellent. The light fastness was improved by 0.5-1 grade by the addition of a UV absorber.

Recently, cardiac injury due to blunt thoracic trauma appears to be increasing in frequency. The rising incidence of this mishap may relate to the absolute increase in automobile accidents as well as to more universal recognition that cardiac damage may have been sustained. We have experienced a rare case of ventricular septal defect caused by non-penetrating thoracic trauma. Of further interest is the history of chest trauma, clearly resulting in rupture of the chordae tendineae of the tricuspid valve successfully treated by operation-re-placement with two, 6 - 0, double-armed, expanded polytetrafluoroethylene sutures-2 months later. The unique combination of ventricular septal defect and rupture of the chordae tendineae of the tricuspid valve secondary to non-penetrating thoracic trauma is presented below to emphasize another variety of cardiac injury.

현재 연약지반의 개량 및 구조물기초 지반의 보강을 위하여 약액주입공법 및 고압분사주입공법 등의 주입공법이 널리 행해지고 있는 실정이다. 이에 본 연구에서는 00교 교대 전면 옹벽기초 하부지반을 고압분사주입공법을 이용해 보강한 사례로서 설계 및 시공, 시험 자료를 분석하고, 보강작업에 따른 지반의 개량효과를 분석하였다. 개량효과학인을 위한 시추조사와 시추공영상 촬영 이미지 관찰결과에서는 고압분사에 의해 양호한 상태의 고결체(토사 + 시멘트 페이스트)가 형성되었음을 확인 할 수 있었으며, 고결체와 원지반의 복합지반상에서 실시한 평판재하시험 결과 및 시추조사시 채취된 고결체 Core에 대해 실시한 일축압축강도시험 결과에서도 설계시 가정한 값을 모두 만족하는 것으로 나타나 연약지반의 강도가 개량되어 안정성을 확보한 것으로 확인되었다.

A barley(Hordeum vulgare L.) cultivar 'Youjin' with hooded spike type having good silage quality was developed at National Institute of Crop Science, RDA in 2016. 'Youjin' showed both high yielding and cold resistance through the preliminary and advanced yield trials(PYT, AYT) from 2012 to 2013. We conducted regional yield trials(RYT) of 'Youjin' in six locations around Korea for three years from 2014 to 2016. It had erect plant type, growth habit of II, the green leaf and hooded awn type. In the paddy field its heading date was April 24 and the maturing date was May 25. Plant height was 99 cm and the number of spikes per ㎡ was 696. It has high rate of leaf blades, resistance to BaYMV(Barley Yellow Mosiac Virus) and good winter hardiness. The average dry matter of Youjin was about 17.2 MT ha^-1 in the field. And feed quality of 'Youjin' was 10.6% of crude protein content, 24.8% of ADF(Acid Detergent Fiber), 43.5 % of NDF(Neutral Detergent Fiber), 69.1% of TDN(Total Digestible Nutrients). And also 'Youjin' had grade I of silage quality.

This study was conducted to develop an organic control method of two spotted spider mite(Tetranychus urticae) by using cooking oil and yolk mixture(COY) through evaluating its acaricidal activity in laboratory and green house. In laboratory, there is no significant difference in acaricidal activity against T. urticae within the COY including soybean, canola(rape seed), sunflower and olive oil. The acaricidal activity against T. urticae. increased from 17.6% to 94.1% as the COY became concentrated between 0.1% to 1%. The COY acricidal activity was effected by the quantity of treatment according to application methods. The COY dealt with T. urticae eggs presented 95% of the ovicidal activity. In rose greenhouse damaged by T. urticae, the COY(0.3%) was sprayed three times and resulted in the high control value of mites between 69.0% to 89.6%.
