Reverse Reconstruction of the Rongorongo System
Milton Kim 한국언어학회 2017 언어 Vol.42 No.3
Hieroglyphic writings or scripts of Easter Island as known as Rongorongo and Rapa Nui readings or transcripts of Rongorongo made by the natives have fascinated scholars and researchers since its discovery. Numerous translations have been published, but none of them has been widely accepted. It has been concluded by many anthropologists and researchers that Rongorongo was proto-writing and an idiosyncratic mnemonic device that did not directly represent language. In an attempt to reconstruct Rongorongo writing and reading systems, this article will introduce the cascaded-crust model which is used to explain how a lengthy Rongorongo script can be divided into smaller script segments and each script segment can be independently handled. Nonetheless this article does not provide with an explanation how Rongorongo script can be transcribed into Rapa Nui, but it will be explained with numerous examples how the split-and-merge method is used to make the sensible translation from Rongorongo transcript. A hypothetical relationship between Easter Island and other indigenous regions such as Indus Valley and Northeast Asia based on Genographic Human Migration Map will be presented from the perspective of cultural migrations. For the demonstration of proposed methodology, two full translations of Échancrée and Great Washington tablets will be presented.

[論文] Computation of the Flow Field around a Butterfly Valve
김철호(C.H.Kim),최정명(J.M.Choi),M.Behnia(M.Behnia),B.E.Milton(B.E.Milton) 한국자동차공학회 1992 오토저널 Vol.14 No.1
대도시의 자동차 배기가스에 의한 대기오염문제는 날로 심화되어 가고 있으며, 그 규제 역시 매우 엄격해지고 있다.<br/> 배기가스의 문제는 연소실내에서의 고효율연소에 의해 개선될 수 있으며, 이를 위해서는 혼합가스 생성장치에서의 잘 미립화된 혼합가스의 생성에 관한 미지적 연구가 필수적이다.<br/> 본 연구에서는 범용 유체 유동해석, 프로그램을 이용하여 Butterfly 밸브 주위에서의 공기의 흐름현상을 예측하였으며, 밸브의 손실계수(Kv)를 심험치와 비교하여 보았다. 또한 압축성과 비압축성 유체 유동해석의 비교, Residual Mass(R.M)의 최적치 정의에 의한 CPU 시간의 최소화, Numerical Grid Size의 해석결과에 미치는 영향 등에 관해 알아보았다.

[論文] Numerical Experiment for Compressible Effects around a Butterfly Valve
김철호(C.H.Kim),M.Behnia(M.Behnia),B.E.Milton(B.E.Milton) 한국자동차공학회 1993 오토저널 Vol.15 No.2
내연기관의 혼합 가스 생성 장치로 홉입되는 공기의 유량을 조절하기 위해 Butterfly 밸브가 사용된다. 이밸브는 유량의 제어에는 매우 유용한반변, 밸브 후면에서의 복잡한 공기의 유동 현상[6]으로 인하여 혼합가스의 생성에 장해적인 요소를 제공하기도 한다. 특히 밸브가 많이 닫힌 상태에서는 밸브와 관로벽 사이의 간격이 좁아지는 Throttling 현상으로 인하여, 엔진에 고 부하시 흡입되는 공기의 양이 증가하게 되어, 밸브 주위에서 공기 속도의 급증으로 인하여 유동장의 압축성 형상을 기대할수 있다. Throttl의 Choking 현상으로 인하여 공기의 입자는 운동에너지를 잃게 되고, 궁극적 혼합가스의 생성에 영향을 미쳐 엔진성능의 저하를 초래하게 된다. <br/> 본 연구에서는 실제 엔진(Central Fuel Injection Engine, 5 liters) [1]의 흡인 manifold를 model-ling하여, 특히 밸브가 많이 닫힌 상태에서, 밸브 주위에서의 난류 유동의 압축성 현상을 정량적으로 분석해 보았다.

야생귀리 Avena sterilis 의 종자휴면을 타파하기 위하여 알콜, 산소, 온수, 저온, thiourea, 제베레린 등을 처리하여 그것들의 효과에 대해서 연구하였다. Thiourea는 약간의 효과만을 보였고 지베레린과 저온처리는 큰 효과를 보였다. 다른 처리들은 아무 효과도 없었다. 1. 지베레린처리 5ppm, 50ppm, 500ppm 중 500ppm은 가장 효과가 컸으며 제1소수에 대해서는 거의 100% 제2소수에 대해서는 66~96%의 효과를 보였다. 지베레린의 효과는 처리농도에 따라 그리고 Avena sterilis 계통간에 차이가 컸으며 그 차이는 통계분석에서도 유의성이 있었다. 2. Thiourea의 처리는 이 실험에서 제1고농도이었던 0.625 x 102 M에서 가장 효과적이었으나 전체적으로 볼 때 thiourea의 효과는 저조하였다. 3. 섭씨 3도를 유지하는 냉장고내에서 1주일간 저온 처리한 제1소수종자들은 90% 제2소수종자들은 10~66%의 발아율을 보이었다. 저온처리에 의한 발아율의 차이는 계통간에도 현저하였다. Dormancy breaking methods were studied on Avenasterilis seeds. The treatments were: application of alcohol, hot water, low temperature, pure oxygen, thiourea and gibberellic acid. Thiourea treatment with 3 different concentrations (0.25 x 10-2 M, 0.625 x 10-2 M, 1.25 x 10-2 M) had little effect in breaking dormancy. Gibberellic acid treatment applied at 5ppm, 50ppm, 500ppm were effective and maximum germination was obtained with 500ppm. Low temperature treatment at 3~circC for a week in a refrigerator was also very effective in breaking dormancy. Other treatments were not effective. In all cases, primary seeds germinated significantly better than secondary seeds. Different A. sterilis strains varied significantly in their response to gibberellic acid treatment. Different concentrations of gibberellic acid also gave significantly different responses in breaking dormancy.

Inheritance of infection cushion formation by rhizoctonia solani kühn on rice leaf sheath
Kwang Ho Kim(金光鎬),밀톤 씨 러쉬(Milton C. Rush) 한국육종학회 1986 한국육종학회지 Vol.18 No.2
Number of infection cushion formed by Rhizoctonia solani Kühn and the causal pathogen of rice sheath blight disease were observed to investigate the inheritance pattern of prepenetration activity of the fungus using four rice crosses. Tadukan and Tx765433, which are resistant and moderately resistant to sheath blight disease, respectively, have same dominant gene which controls infection cushion formation, but a moderately resistant variety Nortai has different dominant gene over Tadukan’s. F₁, F₂, and F₃ populations of two crosses between resistant and susceptible parents, Tadukan/Labelle and Tx765433/Labelle, revealed that infection cushion formation is governed by a single gene of host plants, and that the varietal ability to repress infection cushion formation on rice tissues is dominant over the inducement of infection cushion formation. It is apparent that wax deposits on rice leaf sheath surface are inhibitory to infection cushion formation in F₂ population of a cross, Tadukan/Labelle.

Variance components estimation for farrowing traits of three purebred pigs in Korea
Lopez, Bryan Irvine,Kim, Tae Hun,Makumbe, Milton Tinashe,Song, Chol Won,Seo, Kang Seok Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.9
Objective: This study was conducted to estimate breed-specific variance components for total number born (TNB), number born alive (NBA) and mortality rate from birth through weaning including stillbirths (MORT) of three main swine breeds in Korea. In addition, the importance of including maternal genetic and service sire effects in estimation models was evaluated. Methods: Records of farrowing traits from 6,412 Duroc, 18,020 Landrace, and 54,254 Yorkshire sows collected from January 2001 to September 2016 from different farms in Korea were used in the analysis. Animal models and the restricted maximum likelihood method were used to estimate variances in animal genetic, permanent environmental, maternal genetic, service sire and residuals. Results: The heritability estimates ranged from 0.072 to 0.102, 0.090 to 0.099, and 0.109 to 0.121 for TNB; 0.087 to 0.110, 0.088 to 0.100, and 0.099 to 0.107 for NBA; and 0.027 to 0.031, 0.050 to 0.053, and 0.073 to 0.081 for MORT in the Duroc, Landrace and Yorkshire breeds, respectively. The proportion of the total variation due to permanent environmental effects, maternal genetic effects, and service sire effects ranged from 0.042 to 0.088, 0.001 to 0.031, and 0.001 to 0.021, respectively. Spearman rank correlations among models ranged from 0.98 to 0.99, demonstrating that the maternal genetic and service sire effects have small effects on the precision of the breeding value. Conclusion: Models that include additive genetic and permanent environmental effects are suitable for farrowing traits in Duroc, Landrace, and Yorkshire populations in Korea. This breed-specific variance components estimates for litter traits can be utilized for pig improvement programs in Korea.
