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.

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.

한국증권시장(韓國證券市場)에서 거래가격분포(去來價格分布)와 가격제한폭(價格制限幅)의 영향(影響)

박종호,Park, Jong-Ho 한국재무관리학회 1992 재무관리연구 Vol.9 No.2

본 연구에서는 우리나라 시장이 미국시장과 다른 점을 이용하여 시가와 종가를 비교하여 동시호가방식(同時呼價方式)과 접속매매방식(接續賣買方式)의 차이를 추정하는 것이 적절한 것인지와 거래가격에 대한 가격제한폭(價格制限幅)의 영향(影響)을 살펴보았다. 여기서는 가격제한폭의 영향을 고려하기 위해 수익률이 아니라 절대가격변동(絶對價格變動)을 대상으로 하였다. 결과는 다음과 같다. 1) 일별 그리고 하루중 가격변화의 분포는 정규분포라고 할 수 없다. 2) 종가가 아니라도 가격제한폭의 영향을 받으며 상한가가 하한가보다 2.5배 이상 주가 변동을 제약한다고 할 수 있다. 시간대로는 종가를 제외하고는 오전종가에서 그 영향이 가장 크다. 3) 동시호가와 접속매매 방식에서 분산과 자기상관계수의 일관성 있는 차이를 발견할 수 없었다. 따라서 시가의 분산이 종가의 분산보다 크다는 결과는 거래방식의 차이뿐만아니라 하루중 첫번째 거래와 마지막 거래라는 특정 시간대의 가격이기 때문에 갖는 특성도 중요하다. 4) 각 시간대 별 가격 변화가 동일한 분포를 갖는가를 비모수 검증 방법에 의해 검증했을 때 접속매매인 오전종가와 오후 접속매매 종가의 분포는 다르다고 할 수 없었으며 시가와 종가는 다른 시간대의 분포와 유의하게 달랐다. 5) 하루중 어느 시간대에 가격변화의 분산이 가장 큰가를 검증한 결과 오전시가에서 오전종가까지 시간에서 분산이 가장 켰다. 그 다음으로는 오후 접속매매 종가에서 오후동시호가 종가까지로 이 시간대는 거의 시간차가 없다는 점에서 놀라운 현상이라 하겠다. 6) 종가를 제외하고는 모든 시간대에서 가격반전현상이 있었다. 이러한 현상은 거래시간 동안은 시장에 새로운 정보가 계속 도달하지만 비거래시간에는 정보가 도달하지 않아 이전 정보에 대해 조정하게 되며 이 조정에서 관성을 갖는다고 할 수 있다.

테레프탈산으로부터 합성한 알칼리 수용성 분산염료의 염색성과 견뢰도에 관한 연구

박종호,이권선,김성동,Park Jong Ho,Lee Kwon Sun,Kim Sung Dong 한국섬유공학회 2005 한국섬유공학회지 Vol.42 No.1

Dyeing and fastness properties of alkali-clearable disperse dyes of diester type, which were synthesized using diazo components derived from terephthalic acid, have been studied. They had good build-up properties and showed high exhaustion on regular polyester fiber. Washing and abrasion fastnesses of dyed polyester fabrics were excellent due to the solubility of the dyes in alkaline solution. Increase in molecular weight by introducing bulky sub-stituents to the dye improved sublimation fastness, while the addition of cyano group improved light fastness as expected. Fine denier polyester fabric dyed with the new disperse dye also exhibited excellent washing fastness. The newly synthesized dye barely stained cotton fiber, and gave good washing fastness of polyester/cotton blended fabric dyed by a one-bath dyeing method.

분산염료 분자구조에 따른 PU-함침 폴리에스터의 염색성

박종호,김성동,Park, Jong-Ho,Kim, Sung-Dong 한국섬유공학회 2008 한국섬유공학회지 Vol.45 No.3

Disperse dyes having different molecular structures were prepared and their dyeing properties on PU, PET and PU-coated PET were studied. A disperse dye with common structure showed faster absorption rate into PU for its high affinity to PU at low temperature and this resulted in faster dyeing rate on PU-coated PET than on PET. On the other hand, a disperse dye having bulky structure was adsorbed into both PU-coated PET and PET at similar rate and it showed little affinity to PU in the whole dyeing temperature range. The amounts of disperse dyes eliminated from substrates by reduction clearing and washing fastness test were also measured. It was found that the disperse dye with bulky structure slipped out of PU in reduction clearing and washing fastness test in smaller quantity than the disperse dye with common structure. This phenomenon was corresponding well with the result of washing fastness test.

폐실질안의 신경초종 체험 1례

박종호,백희종,Park, Jong-Ho,Baek, Hui-Jong 대한흉부심장혈관외과학회 1997 Journal of Chest Surgery Vol.30 No.5

In this paper, we present an extremely rare case of a primary intrapulmonary neurogenic tumor, in which localization of S-100 protein was investigated using immunohistochemical staining. The patient, who was a 47 year old man, experienced no symptoms, however, a routine chest X-ray revealed a round tumor like shadow in the hilar area of left lung. To confirm and cure the mass, surgery was performed. Histopathological examination of the excised tumor revealed it to be a primary intrapulmonary neurilemmoma. Immunohistochemical staining demonstrated the presen e of S-100 protein in the tumor cells.
