The relevant restrictions for the separability test at the mean value were employed as following: γ??(β? + α?) - γ??(β? + α?) + (α?β? - α?β?)α? = 0 The null hypothesis that meat commodities are separable with non-meat food was not restricted at a 5% level of significance. This implies that the separability assumption could be strongly plausible in the empirical work. Own-price elasticities were negative. The fact implies meats concerned are normal goods as expected. The expenditure elasticities are saying that non-meat food is more elastic that meats. The compensated cross price elasticities shows some strong competitiveness in expenditures and/or strong substitutes between beef and pork in recent years. Also the rest of meats are net substitutes in the analysis period.

정부개혁의 비판적 성찰과 전략적 대안

전영평,김병섭,이승종,Robert F. Durant 大邱大學校 社會科學硏究所 2001 社會科學硏究 Vol.9 No.2

세계 각국의 정부 개혁 추세에 맞추어 한국 정부도 정부 개혁을 수행하고 있지만 그 성과에 대한 정확한 평가에 대해서는 의견이 일치하지 않고 있다. 무엇보다도 정부 개혁을 만병통치약으로 받아들이는 태도를 경계하여야 하며, 성과에 대한 성급한 판단 이전에 정부개혁과 관련한 다양한 문제점들을 잘 살펴보는 일이 선행될 필요가 있다. 이 연구에서는 김대중 정부의 개혁 정책-정부구조조정과 인사개혁의 두 차원-의 문제점에 관하여 비판적인 성찰을 하고, 한국의 정부개혁의 위상을 파악하고자 하였다. 비록 엄밀한 실증적인 분석을 하지는 못하였으나 질적인 담론을 통하여 김대중 정부의 개혁의 문제점 및 과제를 제시하고자 하였다. 정부 구조 조정 분야에서는 1) 개혁의 방향성 및 일관성 문제, 2) 조직 분권화 및 민주화 문제, 3) 정책 조정 문제, 4) 권한의 하부 위임 문제, 5) 인력 감축 관리 문제, 6) 공무원 전문성 제고 문제, 7) 책임운영기관제도의 문제, 8) 개혁의 시기와 방법 문제 등이 지적되었으며, 인사개혁(개방형임용제도) 분야에서는 1) 민간과 공직간의 신뢰관계 축적 미흡, 2) 공직과 민간의 이익과 목표간의 부합도가 낮은 상황에서 개방형 직위제가 적용, 3) 공직과 민간간의 협력 훈련 경험 부족, 4) 개방형직위제의 선정 작업이 공직 내부에서의 토의를 배제한 채 외부의 경영진단기관의 판단에 따라 하향적으로 적용되었다는 문제가 지적되었다. 결론적으로 이 연구는 한국의 정부 개혁은 빈약한 정부 개혁 논리 속에서 내부적인 합의와 신뢰관계를 구축하지 못한 채 제대로 된 위상을 정립하지 못하고 있기 때문에 향후 정부 개혁이 많은 시행 착오를 겪을 것으로 예상하였다.

Byon, Andrew Sangpil. 2003. The Korean Speech Act of Refusals: Sociopragmatic Analysis. 사회언어학, 11(1). 외국어 습득에서의 화용론의 역할에 관한 관심이 높아지면서 중간 언어 화용론(jnterlanguage pragmatics)에 관한 연구가 최근 들어 많이 이루어지고 있다. 그러나 영어를 모국어로 하는 KFL 학습자를 대상으로 한 중간 언어 화용론 연구는 매우 미흡한 실정이다. 이에 본고에서는 보다 활발한 한국어 중간 언어 화용론 연구를 위해 먼저 기존의 중간 언어적 화용론 자료 수집 방법론(data-gathering methodology)에 대해 논의하고 한국어를 이용한 written discourse completion task(DCT)를 Brown and Levinson(1987)의 두개의 사회적 변수인 power와 distance에 근거해서 개발하였다. 그 DCT를 이요해서 30명의 한국 대학생과 30명의 영어를 모국어로 하는 한국어 학습자의 한국어 거부 발화 행위를 비교 조사 분석 해 보았다. 그리고 모국어 전의 영향(L1 transfer effect)을 분석하기 위해 30명의 미국 대학생의 영어 거부 발화 행위를 조사하여 한국어 학습자의 결과와도 비교했다. 분석 결과로는, 먼저 12 종류의 거부의 주된 행위 전략(refusal head acts)과, 5종류의 거부 지지 행위 전략(refusal supportive move)을 사용하고 있음을 알아냈으며, 학습자의 한국어 거부 발호 행위에서 나타난 모국어 전이의 영향에 대해 논의했다. 그리고, 사회적 변수가 발호 행위에 미치는 영향을 Sohn(1986)의 수직론(hierarchicalism)과 간접론(indirectness)에 근거해서 한국 대학생과 학습자의 발화 행위를 설명했다. 본고의 결론에서는 이런 연구 결과들을 실제로 한국어 중간 언어 화용론 연구와 외국어로의 한국어 교육에 어떤 식으로 반영시켜야 할 지를 논의했다.

Effect of Post-N+Implantation on the Microstructure of the Interfacial Non-Cubic BN Layers

Plasma source ion implantation has been applied as a post treatment in order to modify the interfacial sp^2 bonded layer of the cubic BN (cBN) films. The effect of ion irradiation on the microstructure of the noncubic BN layer was investigated. From HRTEM observation, the thickness of the BN layer of the representative sample was about 100 nm including 15 nm of initially grown non-cubic layer at the interface between a substrate and the cubic layer. At optimal plasma source implantation conditions, an acceleration voltage of 50 keV and an ion dose of 2×10 exp(16) ions/㎠, the microstructure of the interfacial non-cubic BN layer was changed. It was noticed that the ion irradiation caused the recrystallization of the amorphous phase and transformed the small crystallites into another phase. The micro-hardness of the complex consisting of a hard and soft layer increased as a result of phase transformations. This was caused by atomic displacements in the initially grown amorphous and hexagonal layers. The atomic displacements calculated by the TAMIX code were in the range of 0.31∼0.52 nm per atom within 70∼100 nm in depth.

Beneficial Effects of Dietary Antiacarcinogenic Conjugated Linoleic Acid(CLA) on the Performances of Laying Hens and Broilers

Byon, Jai-II,Park, Sook-Jahr,Park, Kyung-Ahr,Ha, Jeung-Key,Kim, Jeong-Ok,Ha, Yeong-Lae The Korean Society of Food Science and Nutrition 1996 Preventive Nutrition and Food Science Vol.1 No.1

Effects of conjugated linoleic acid(CLA), known as an effective anticarcinogen in several aminal models, on the egg production and egg weight of laying hens, and the weight gains of broilers were investigated. CLA was synthesized from corn oil by the alkaline isomerization method and purified by the low-temperature precipitation method. Diets for laying hens and for broilers were synthesized to meet the specification of their NRC standard rationals. Two separated experiments(Experiment I and II) were conducted for laying hens. in experiment I, 45 hens(300 days of age) were divided into 15 hens per treatment group; each hen was housed in wired cage located in a temperature and humidity-controlled house and adopted to the control diet. One week later, each group was subjected to one the four treatment groups for 5 weeks : control, 1.0% CLA, 2.5% CLA and 5.0% CLA diets. Diet and water were ad libitum. The condition of experiment II was the same as that of experiment I except for the addition of 5% corn oil diet and the extension of feeding period to 7 weeks. Egg production, egg weight and feed intake were recorded every week. Forty-five broilers(10day of age) were adopted to the control diet for a week and then switched to the treatment diets for 5 weeks : control, 1.0% CLA, 2.5% CLA, 5% CLA and 5% corn oil, Body weight and feed intake of broilers were measured every week. Diets supplemented with various amounts of CLA enhanced the egg production and increased the egg weight regardless laying hen's age(150 days or 300 days) as compared to control diet. The most effective diet for the egg production and egg weight of young hens(150 days of age) was found to be 1.0% CLA diet, but relatively higher CLA diet(2.5% CLA) was required for old hens (300 day of age) to obtain similar results as seen in younger hens. All hens treated with CLA ate greater amount of feed than control hens. Broilers treated with various amount of CLA ate less feed as compared to control ones, but the body weight gain was greater than the control broilers. These results indicate that CLA enhanced the egg production and agg weight of laying hens, and increased the body weight gain of broilers with less diet consumption.

Extended M-ary QT algorithm for RFID system

Byon-Gon KIM,Kwan-Woong KIM 한국정보통신학회 2014 2016 INTERNATIONAL CONFERENCE Vol.6 No.1

Most important technical issue in radio frequency identification (RFID) is to correctly and quickly recognize a number of tag IDs in the reader’s communication range. Unlike the probabilistic RFID tag recognition schemes, a query tree(QT) based protocol guarantees to identify all the tags, where the distribution of tag IDs is assumed to be uniform. In this paper, we proposed an extended M-ary QT protocol, which effectively reduces unnecessary query-response cycles by using non-sequential m-bit recognition method. The simulation results show that the proposed scheme significantly outperforms M-ary QT schemes in terms of identification time, efficiency and communications overhead.

Effect of roll gap adjustment on exit cross sectional shape in groove rolling—Experimental and FE analysis

Byon, S.M.,Na, D.H.,Lee, Y. Elsevier 2009 Journal of materials processing technology Vol.209 No.9

<P><B>Abstract</B></P><P>We machined work roll with groove worn down as well as groove with no wear. We then performed a pilot hot rod rolling test at temperature of 1000°C using plain carbon steel (0.1% C) as the roll gap decreases from reference roll gap (6.5mm) to 3.5mm. To understand better the effect of roll gap (i.e., section height) adjustment on the exit cross sectional area (ECSA) variation of workpiece in a two-stand groove rolling process with wear is considered, we carried out a series of three dimensional finite element analysis. Results reveal that variation of ECSA is almost linearly proportional to roll gap change while the roll gap decreases from reference roll gap (6.5mm) to 3.5mm. In oval groove rolling, the exit cross sectional shape and area predicted by FEA is in a good agreement with those measured. In round groove rolling, however, some deviations between FEA and experiment are observed because of roll groove geometry coupled with cross sectional shape of incoming workpiece. In the two-stand groove rolling, the effect of roll gap adjustment at each stand on the exit cross section of workpiece is somewhat different, in comparison with single-stand groove rolling. The roll gap adjustment at the previous stand has a more influence on the ECSA of workpiece than that of the next stand.</P>
