The modification of rice powder was attempted by treatment of acetic acid and epichlorohydrin to improve the functional properties of baby food. The initial gelatinization temperature of rice powder determined by amylograph was decreased from $79.5^{\circ}C$ to $63^{\circ}C$ by modification. The apparent and maxium viscosity of rice paste at $95^{\circ}C$ before and after modification were increased from 92B.U. to 236B.U. and from 100B.U. to 202B.U., respectively. The light transmittance of modified rice paste was increased from the temperature of $60^{\circ}C$ and by increasing the degree of substitution at the fixed temperature, while decrease more or less by the treatment of epichlorohydrin. The degree of retrogradation of the paste was decreased from 28.7 to 18.0 upon modification. The rate of syneresis of modified rice powder was decreased with increasing the drgree of substitution and ,the extend of epichlorohydrin treatment. Syneresis was not observed when acetylated rice powder whose DS value is 0.048 was treated with 0.25% of epichlorohydrin for the formation of cross-linkage. The addition of modified rice powder in preparation of semi-solid type infant food could improve the quality without lowering overall digestibility.

최정선,이희성,이근배,Choi, Jung-Sun,Lee, Hi-Sung,Lee, Keun-Bai 생화학분자생물학회 1979 한국생화학회지 Vol.12 No.4

Sarcoma 180 복수암 세포를 마우스에 이식시킨 후 3일, 7일 및 14일 만에 각각의 마우스로부터 복수를 취하여 branched chain amino acid transaminase (EC 2.6.1.6)의 활성도 및 isozyme의 pattern을 관찰하였다. 효소의 활성도는 Ichihara and Koyama의 방법으로 측정하였으며, isozyme은 ammonium sulfate에 의한 침전 및 DEAE-cellulose column chromatography에 의하여 분리하였다. 이상과 같이 하여 다음과 같은 결론을 얻었다. 1. 복수의 branched chain amino acid transaminase의 활성도는 Sarcoma 180 복수암 세포 및 다른 정상 조직에 대하여 낮았다. 2. 기질에 대한 효소활성도는 L-isoleucine이 가장 낮았다. 3. Sarcoma 180 복수암 세포를 이식시킨지 3일, 7일 및 14일 만에 채취한 복수의 BATA 활성도는 복수 1 ml 당 59.32 unit, 60.17 unit 및 71.19 unit로 14일 것이 가장 높았다. 4. 7일 만에 채취한 복수의 BATA를 DEAE-cellulose column chromatography로 분리한 결과 용출액인 인산염 완충액의 농도가 20mM, 150mM 및 200mM에서 Enzyme I, II 및 III이 각각 검출되었다. 비활성도는 Enzyme III이 23.62로 Enzyme I 및 II 보다 약 11배 및 6배 높았으며 분포율은 Enzyme I, II 및 III이 각각 10.63%, 59.97% 및 29.40%로 Enzyme II가 가장 많았다. 5. 14일만에 채취한 복수에서는 Enzyme I 및 II가 함유되어 있었으나 Enzyme III은 검출되지 않았다. 비활성도는 Enzyme II가 13.52로 I보다 약 6배 높았으며 분포율은 Enzyme I 및 II 가 각각 46.52% 및 53.48% 이었다. 6. Sarcoma 180 복수암 세포에 함유되어 있지 않은 Enzyme II를 복수에서 분리한 것은 큰 의의가 있는 것으로 생각된다. 7. 복수암 세포를 이식시킨 후 시간의 경과에 따라 BATA의 isozyme pattern이 변화됨을 알 수 있었다. The activity and isozyme patterns of branched chain amino acid transaminase (EC 2.6.1.6) in ascitic fluid harvested at 3, 7, 14 days after transplantation of Sarcoma 180 ascites tumor cells in mice were studied. The activity of branched chain amino acid transaminase was measured by the method of Ichihara and Koyama. Isozyme patterns of the enzyme were also examined by DEAE-cellulose column chromatography. The results obtained were as follows; 1. In ascitic fluid, the activity of branched chain amino acid transaminase were relatively low compared with those of Sarcoma 180 ascites tumor cells. 2. The enzyme activity for leucine was found highest. 3. The activity of this enzyme in ascitic fluid harvested at 14 days after transplantation was found highest. 4. Ascitic fluid harvested at 7 days after transplantation contained isozyme I. II and III of branched chain amino acid transaminase. The relative amounts of the above three isozymes were 10.63%, 59.97% and 29.40%, respectively. It was realized that Enzyme I and III catalyzed the transamination of leucine. isoleucine and valine, but Enzyme II was only specific for leucine. 5. In ascitic fluid harvested at 14 days after transplantation, the specific activity of Enzyme II was found to be 6 times higher than that of Enzyme I and the relative activity of Enzyme I and II in the above fluid was 46.52% and 53.48%, respectively. 6. The chromatographic elution profiles of the Enzyme I, II and III from the ascitic fluid were found to be very similar with those of normal rat liver and brain.

Starch plays an important role in textural quality of infant food which is mainly affected by retrogradation of starch during storage. The acetylated rice was prepared and its physicochemical properties were evaluated to improve the textural quality of infant food when added. When the rice powder was reacted with acetic acid with its increasing concentration from 0.1 M, 0.2 M to 0.3 M, the amount of acetyl group and degree of substitution were increased by 0.39%, 0.8% and 1.27%, and by 0.0014, 0.031 and 0.048, respectively. The initial gelatinization temperature of rice paste determined by amylograph was decreased from $79.5^{\circ}C$ of unmodified rice to $67.5^{\circ}C$ of acetylated rice whose DS is 0.048. The apparent and maxium viscosity of rice paste at $95^{\circ}C$ before and after modification were increased from 92 B.U. to 201 B.U. and from 100 B.U. to 236 B.U., respectively, The degree of retrogradation and rate of syneresis were decreased from 28.7 to 18.8 and from 0.47% to 0.25%, respectively with increased by DS from 0 to 0.048. The digestibility rate of rice powder decreased from 9.19 of natural rice powder to 7.54 of acetylated rice powder whose DS is 0.048. In United State, there is no serious problem in total digestibility because only 4% of modified rice powder is added in production of infant food.

국제회계기준(K-IFRS)도입과 관련된 세제개편의 평가와 나아갈 방향

최정선 ( Jung Sun Choi ) 서울시립대학교 법학연구소 2011 조세와 법 Vol.4 No.1

IFRS 도입에 따른 법인세법의 개정과 그에 대한 평가 및 향후 개정을 위하여 추가적인 논의가 필요한 사항에 대해 살펴보았다. 첫째, 국제회계기준의 도입으로 인해서 결산조정사항과 관련된 과세소득이 현저히 증가할 경우 특례를 두어 과세이연 혜택을 주거나 특정 항목에 한정하여 신고조정으로 변경하는 방법으로 개정되고 있는 현실이다. 그러나 결산조정의 논의 이전에 기업회계와 세무회계간의 관계정립에 대한 논의의 선행이 필요하다. 둘째, 세제개편의 대원칙으로 기업회계기준 이원화에 따른 기업간의 세부담의 불형평을 막고자 평가손익을 불인정하는 것을 원칙으로 하나, 급격하게 세무조정사항이 증가하는 단점이 있다. 세무조정의 부담을 완화시키기 위해 신뢰할 수 있는 공정가치나 일시적 차이에 해당하는 경우 등은 세법상 인정하는 방향으로의 개정이 필요해 보인다. 셋째, 감가상각비에 대해서 결산조정을 유지하되 감가상각비 감소에 따른 세부담 증가의 완화를 위해 신고조정을 허용하는 특례를 도입하였다. 그러나 임시방편적인 특례규정으로 둘게 아니라 IFRS규정의 제·개정의 완료시기에 맞춰서 신고조정으로 전환하는 방향으로 개정되어야 할 것이다. The purpose of this study is to evaluate 2010 tax reform according to IFRS adoption in Korea. Also this study makes some suggestions for Korean tax reform for the future. First, the current relationship between accounting standards (IFRS) and Korean tax codes (tax laws) should be reconsidered. Second, K-IFRS apply the fair value evaluation method when they measure the values of the tangible and intangible assets, etc. However, the tax law needs not adopt the fair value evaluation, because the profits and losses from changes in fair value are yet not realized and therefore not taxable. Some exceptions can be applied in case of the items such as financial asset at fair value through profit or loss because the fair value is not assessed arbitrarily and the profit or loss will be realized soon. Finally, because the changes in depreciation and allowance for bad debts is temporal in the condition of IFRS revision in 2013, these changes should be revised.

헨리 제임스의 후기 작품에 나타나는 분열적 현상으로서 자아 연구

최정선 ( Jung Sun Choi ) 근대 영미소설 학회 2005 근대 영미소설 Vol.12 No.2

This essay aims to investigate the problem of self as divided ego in his later works, especially "The Jolly Corner"(1908) and The Sense of the Past (1917). In the works, James`s heroes pursue the "other" selves who are similar to heroes, but are very antithetical to them. In "The Jolly Corner" Spencer Brydon searches for the ghost who takes after him in the house where he lived in his youth. In The Sense of the Past the present Ralph Pendrel plays the role of the past ancestor who looks like him, but avoids him. In my study I suggest that in these searches of heroes` the relationship between the hero and the other self represents that of ego and alter ego respectively. Thus the heroes` searching for the other selves symbolizes their efforts to find the alter ego hidden and repressed in their "official" ego and ultimately reach the unified ego. In "The Jolly Corner" Brydon tries to pursue the ghost, which is finally identified as his alter ego repressed in his public ego. In The Sense of the Past Ralph in the past is the self containing the alter ego representing the desire that the present Ralph has hidden and repressed. In order to understand self it is necessary for Ralph to play the role of the alter ego, his ancestor, and to experience his conflicts with the other characters of the past in the old house in Mansfield Square. Ultimately the heroes obtain the complete sense of self in their searches. Brydon faints in his pursuing the alter ego and achieves his full understanding of ego, waking up in the lap of Alice. Ralph also accepts and understands other characters and gets to full understanding of alter ego. James seems to further indicate that the redemption of unified self requires the relationship with other people and love. This is plausible in the importance of Alice, Aurora and Nan in the process of Ralph`s achieving the unified self.

The potential for brand dilution occurs when new brands merge with an identical image of a parent brand. Despite the significant attention regarding the effects of dilution on brand extension, there is limited research on brand dilution in the beauty industry. This study analyzes the effect of the typicality of extensional type on brand attitude or purchase intention for potential dilution toward beauty brand extension. In addition, we examine the moderating effect of knowledge transfer when customers evaluate the typicality of the extensional type for potential dilution toward beauty brand extensions. For the experiment, 4 description type factorial designs were performed. A total of 219 students participated in the experiment who had experience of visiting a beauty salon. The results are as follows. First, there are significant independent and interaction effects between the typicality and extensional type that reveals differential influences on the attitude or purchase intentions toward extended beauty brands. Second, the knowledge of the parent brand is transferred to extended brands. Third, there is a significant moderating effect of knowledge transfer, as customers evaluate the typicality of the extensional type for the potential dilution toward beauty brand extension. This study provides some theoretical and practical perspectives with some limitations.
