함정혜(Chung Hae Hahm) 한국여성체육학회 2013 한국여성체육학회지 Vol.27 No.1

The purpose of this study was to compare the differences of moral reasoning among general students, sports related majors students, and student athletes in Korea and Japan University. We collected total 612 out of 700 (315 from Korea, 297 from Japan) and 88 questionnaires were excluded questionnaire due to incompleteness and unreliable data. For this study, Hahm-Bellar Values Choice Inventory-16(HBVCI-16), which is a Moral Reasoning Questionnaire on Sports Activities, was used. The collected data was analyzed by t-test, one way ANOVA and two way ANOVA with using SPSS Var. 17.0 statistical package program and result were as follow. First, the Japan student`s overall score of moral reasoning were lower compare to Korean university students. Second, there were 1 % higher score of moral reasoning in woman against man and in younger subjects. Sports majored university students presented 1% higher score against other related students and higher grade students presented 5% higher score against lower grade students. Third, among student athletes of Korea and Japan, although there were no significant differences, it was 0.1% higher among those who engaged in individual sports and 5% higher score in those who have less sports career.

Kang, Young-Sig,Hahm, Hyo-Joon,Rim, Suk-Chul,Kim, Seung-Baum The Korean Society for Quality Management 1994 품질경영학회지 Vol.22 No.1

Most of computer-aided process planning(CAPP) systems have been developed to automate the process planning function. In this paper, we describe an analytical model for a CAPP system in order to improve the performance of production system in flexible manufacturing systems(FMSs) for computer intergrated manufacturing(CIM) architecture. This paper proposes an optimal process planning that minimizes the load time by minimizing the cycle time and the number of workstations using Kang and Hahm's heuristic approach so as to improve the performance of production system under the batch production of discrete products. We also perform simulation using SIMAN language to campare the line utilization of each for various product types. The proposed algorithm can be implemented in existing FMSs for on-line control of product quantity using programmable logic controllers(PLC) and communication devices.

Comparative Glycopeptide Analysis for Protein Glycosylation by Liquid Chromatography and Tandem Mass Spectrometry: Variation in Glycosylation Patterns of Site-Directed Mutagenized Glycoprotein

Hahm, Young Hye,Hahm, Sung Ho,Jo, Hyoun Young,Ahn, Yeong Hee Hindawi 2018 International journal of analytical chemistry Vol.2018 No.-

<P>Glycosylation is one of the most important posttranslational modifications for proteins, including therapeutic antibodies, and greatly influences protein physiochemical properties. In this study, glycopeptide mapping of a reference and biosimilar recombinant antibodies (rAbs) was performed using liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) and an automated Glycoproteome Analyzer (GPA) algorithm. The tandem mass analyses for the reference and biosimilar samples indicate that this approach proves to be highly efficient in reproducing consistent analytical results and discovering the implications of different rAb production methods on glycosylation patterns. Furthermore, the comparative analysis of a mutagenized rAb glycoprotein proved that a single amino acid mutation in the Fc portion of the antibody molecule caused increased variations in glycosylation patterns. These variations were also detected by the mass spectrometry method efficiently. This mapping method, focusing on precise glycopeptide identification and comparison for the identified glycoforms, can be useful in differentiating aberrant glycosylation in biosimilar rAb products.</P>

Development and Present Status of the Seed Potato Program in the Republic of Korea

HAHM, YOUNG-IL,KIM, HWA-YEONG 江陵大學校東海岸地域硏究所 1993 東海岸硏究 Vol.4 No.1

한국의 감자 종서 생산체계는 30년 이상의 역사를 지니고 있으나 1985년까지의 일반적인 발전과정이 Horton등(1988)에 의하여 단 한번 보고되었을 뿐이다. 따라서 본 논문에서는 1986년 이후의 변화를 포함한 한국의 종서 생산체계의 발전과정과 현황을 증식체계의 변화와 바이러스병의 발생을 중심으로 보고하고자 한다. 한국의 종서 생산체계는 1961년에 원원종과 보급종을 처음으로 생산한 이래 증식 및 검정체계가 몇차례 수정되어 현재까지 유지되고 있다. 그러나 1960년대와 1970년대에는 주로 종서의 공급량 증대에 중점을 두었을 뿐 바이러스병의 방제에는 소홀히 하였다. 결과적으로 1970년대 후반에는 종서의 바이러스 이병율이 증가하여 1979년에는 주요 재배작형에 필요한 보급종을 생산하지 못한 바 있다. 그후 조직배양 및 망실재배를 이용한 상위급 종서의 생산으로 1980년대 후반까지는 양질의 종서가 공급되었다. 그러나 1980년대 후반부터 종서의 엽권바이러스 이병율이 증가하여 1988년에는 주요 재배품종의 원종 생산에 실패한 바 있다. 이와같은 문제점을 극복하기 위하여 1989년부터 원원종 생산 단계까지 망실재배를 확대이용하고 있으며 엽권바이러스에 저항성인 신품종의 보급과 기내소피경을 이용한 종서 생산체계의 확립이 추진되고 있다. 더불어 1980년대 후반의 엽권바이러스 이병율 증가의 원인에 대하여 논하였다. The present paper reports the development and present status of the Seed Potato Program in the Republic of Korea with focuses on the change in multiplication system and the occurrence of virus diseases. The Seed Program began by producing the first Foundation and Certified Seed in 1961. During the 1960s and 1970s, the Seed Program primarily emphasized producing adequate amounts of seed potatoes and made relatively simple effort for virus control. As a result, the seed stocks became severely infected with viruses, and the Seed Program failed to produce Certified Seed for major cropping systems in 1979. Since the failure, tissue culture techniques and nethouse cultivation systems were introduced for the production of upper-grade seed stocks, effecting the production of Certified Seed in acceptable qualities during the 1980s. During the second half of the 1980s, however, virus infection rates of the seed stocks increased again, and the Seed Program failed to produce the Registered Seed of the major variety due to a high rate of potato leafroll virus (RLRV) occurrence in 1988. To overcome the PLRV problem, the Seed Program extended the use of nethouses even for the production of Foundation Seed from 1989. In addition, the Seed Program is going to practice utilization of PLRV-resistant varieties and establishment of seed potato production systems using microtubers produced in vitro. Possible reasons for the PLRV increase during the late 1980s are also discussed.

APPROXIMATION ORDER TO A FUNCTION IN $C^1$[0, 1] AND ITS DERIVATIVE BY A FEEDFOWARD NEURAL NETWORK

Hahm, Nahm-Woo,Hong, Bum-Il The Korean Society for Computational and Applied M 2009 Journal of applied mathematics & informatics Vol.27 No.1

We study the neural network approximation to a function in $C^1$[0, 1] and its derivative. In [3], we used even trigonometric polynomials in order to get an approximation order to a function in $L_p$ space. In this paper, we show the simultaneous approximation order to a function in $C^1$[0, 1] using a Bernstein polynomial and a feedforward neural network. Our proofs are constructive.

Predispersed Solvent Extraction of Negatively Complexed Copper from Water Using Colloidal Liquid Aphron Containing a Quaternary Ammonium Salt

Hahm, Hyung Chul,Lee, Dong Woo,Hong, Won Hi,Lee, Tai-Yong,Lee, Choul Ho 한국화학공학회 2003 Korean Journal of Chemical Engineering Vol.20 No.4

Negatively complexed copper ion by complexing agent like EDTA (Ethylenediaminetetraacteic acid) was removed by predispered solvent extraction (PDSE) using colloidal liquid aphrons (CLAs) made out of Trioctylmetylammonium chloride (Aliquat 336) diluted with nonpolar kerosene. PDSE was found to have higher mass transfer rate than conventional solvent extraction under experimental conditions without mechanical mixing. The effect of type of water-soluble surfactants, phase volume ratio (PVR), concentration of anionic Sodium Dodecyl Benzene Sulfonate (SDBS) on PDSE was investigated. In addition, the effect of anionic SDBS on back extraction in PDSE was also studied. Under experimental conditions with enough mechanical mixing, the amount of copper transferred to Aliquat 336 core from the pregnant phase was compared in both PDSE by using anionic SDBS and conventional solvent extraction. It is concluded that PDSE using Aliquat 336 CLA can be used for treatment of negatively complexed copper without the influence of surfactant. To optimize CLAs-based process, stability of CLAs containing a quaternary ammonium salt Aliquat 336 diluted with kerosene in the continuous phase was investigated by measuring the volume released to surface. To destabilize CLAs, H^(+), OH^(-) were added. Stability of CLAs was estimated by comparing the halflife obtained. Break-up of destabilization follows pseudo-first-order reaction kinetics at low ionic strength. But, pseudofirst- order model cannot be applied to a region of high ionic strength.

Characterization of the Nickel Resistance Gene from Legionella pneumophila : Attenuation of Nickel Resistance by ppk(polyphosphate kinase) Disruption in Escherichia coli

Hahm, Dae Hyun,Yeom, Mi Jung,Ko, Whae Min,Lee, Eunjoo H.,Lee, Hye Jung,Shim, In Sop,Kim, Hong Yeoul 한국미생물 · 생명공학회 2002 Journal of microbiology and biotechnology Vol.12 No.1

A 1,989-bp genomic region encoding nickel resistance genes was isolated from Legionella pneumophila, a pathogen for legionellosis. From a sequencing and computer analysis, the region was found to harbor two structural genes, a nreB-like protein gene (1,149 bp) and a nreA-like protein gene (270 bp), in a row. Both genes exhibited a significant degree of similarity to the corresponding genes from Synechocystis sp. PCC6803 (54% amino acid sequence identity) and Achromobacter xylosoxidans 31A (76%). The gene was successfully expressed in E. coli MG1655 and conferred a nickel resistance of up to 5mM in an LB medium and 3 mM in a TMS medium including gluconate as the sole carbon source. E. coli harboring the nickel resistance gene also exhibited a substantial resistance to cobalt, yet no resistance to cadmium or zinc. Since the extracellular concentration of nickel remained constant during the whole period of cultivation, it was confirmed that the nickel resistance was provided by an efflux system like the Ni^2+ permease (nrsD) of Synechocystis sp. strain PCC6803. Since polyphosphate (poly-P) is known as a global regulator for gene expression as well as a potential virulence factor in E. coli, the nickel resistance of a ppk mutant of E. coli MG1655 harboring the nickel resistance gene from L. pneumophila was compared with that of its parental strain. The nickel resistance was significantly attenuated by ppk inactivation, which was more pronounced in an LB medium than in a TMS medium.

MONETARY BANDS AND MONETARY NEUTRALITY

HAHM, SANG-MOON 한국국제경제학회 2002 International Economic Journal Vol.16 No.2

This paper attempts to provide an explanation of the short-run monetary non-neutrality in an economy where agents have full current information and no nominal prices are set in advance. This non-neutrality arises due to the government's setting of nominal target bands. If the current money supply is near the upper bound of the band, any increase in money supply will require the monetary authority to take immediate action to reduce it. This serves to decrease the expected rate of inflation, thus increasing the demand for real balances and production. This paper also shows that if readjustments of nominal target bands are likely to occur, then the positive effect of money on output becomes attenuated. [E32, E52]
