This study was carried out to investigate the effect of the timing and dose of human chorionic gonadotropin(hCG) on oocyte recovery, in vitro fertilization, and preimplantation development in superovulation of mouse. F1 hybrid($C57BL{\times}CBA$) mice were obtained and superovulation was induced in female mice by sequential intraperitoneal injection of PMSG and hCG. In the first series of experiments, mice received 5 IU of PMSG given intraperitoneally, and 48 hours later were injected 1 IU, 5 IU, or 10 IU of hCG respectively. In the second series of experiments, mice received 5 IU of PMSG given intraperitoneally and were injected 5IU of hCG 36, 48, or 60 hours later respectively. 1. When the mice received 5 IU of PMSG given intraperitoneally and 48 hours later were injected 1 ItT, 5 IU, or 10 IU of hCG respectively, there were no differences in the total number of the oocytes obtained from the three experimental groups. When the cultures were examined 48 hrs after the termination of insemination the proportion of unfragmented oocytes which had developed over two-cell stage was observer to be lowest in 10 IU hCG group. When the cultrues were examined 120 hour after termination of insemination the proportion of embryos which had developed to the blastocyst stage was observed to be significantly higher in 10IU hCG group than 5IU hCG group(p<0.05), but there was no difference between 10 IU hCG group and 1IU hCG group. 2. When the mice received 5 IU of PMSG and were injected 5 IU of hCG 36, 48, or 60 hours later respectively, there were no differences in the total number of oocytes obtained from the three experimental groups. When cultures were examined 48 hour after the termination of insemination the proportion of unfragmented oocytes which had developed over two-cell stage was observed to be significantly lower in 36 hour interval group than 48 hour interval and 60 hour interval group(p<0.05). When the cultures were examined 120 hour after termination of insemination the proportion of embryos which had developed to the blastocyst stage was found to be higher in 60 hour interval group than 36 interval or 48 hour interval group (P<0.05), and the proportion of hatching blastocyst was found to be higher in 60 hour interval group as well. In this study, it was concluded that the administration of adequate dose of hCG, and long (60 hour) PMSG-hCG interval were necessary in superovulation of mice($C57BL{\times}CBA$) in order to get a large number of oocytes which had an early oocytes which had an early embryonic developmental capability when fertilized in vitro, and especially it had better have been avoided to administer a large dose of hCG.

Effects of moxibution at the Gwanweon, Jungwan and Joksamlee on the blood picture in rat with transportation stress were determined. Counts of RBC showed a tendency to increase from 6 hours to 12 hours after transportation stress, however in the moxibution group, showed no changes in counts of RBC after transportation stress and the tendency of fluctuation was similiar to those of none stress group. The changes in Hb after transportation stress showed no difference among moxibution group and none moxibution group, however the changes in PCV showed a tendency to increase from 3 hours to 6 hours after transportation stress in two stress group. In the mean values of erythrocytic blood during experimental times, counts of RBC showed a high values (P<.05) in the stress only group, however in the other groups, these values showed no difference (P>.05) among treatment and the values of Hb and PCV showed no difference among 4 treatment groups. In the two stress groups, counts of WBC and Neutrophils showed a tendency to decrease after transportation stress, however the moxibution group was recovered to normal Leukocytes condition on short time compared with those of none moxibution group. In the mean values of Leukocytes during experimental times, counts of WBC and Neutrophils showed a high values and Lymphocytes showed a low values in the stress only group compared with those of other groups, however the stress group with moxibution showed no difference in Leukocytes values compared with those of normal condition group. Monocytes, Basophils and Eosinophils showed no difference among 4 treatment groups(P>.05). Results from this study indicate that the moxibution can tolerate the effects of transportation stress in rat.

연구개발비 회계처리에 대한 테마감리의 효과: 제약·바이오 산업을 중심으로

양승희 ( Seunghee Yang ),임지은 ( Jieun Im ) 한국회계학회 2021 회계학연구 Vol.46 No.5

본 연구는 2018년도 실시된 금융감독원의 연구개발비 회계처리에 대한 테마감리 이 후 감리 대상인 제약·바이오 기업의 연구개발비 회계처리 및 연구개발비 관련 정보의 가치 관련성이 어떻게 변화하였는지 살펴본다. 2015년부터 2019년까지 국내 상장기업을 대상으로 분석한 결과, 테마감리 실시 이후 제약·바이오 기업의 연구개발비 자본화율은 기타 기업의 자본화율에 비해 유의하게 낮아졌다. 이러한 효과는 금융감독원이 테마감리를 사전예고한 2017년부터 나타났으며, 2018년 중 감독지침이 발표됨에 따라 2018-2019년에도 자본화율 감소 효과가 지속적으로 발생하였다. 동 기간 제약·바이오 기업이 제공하는 연구 개발비 정보의 가치관련성은 유의하게 향상되어, 테마감리가 개별 회사들의 자의성과 유연성을 지나치게 제한할 수 있다는 우려에도 불구하고 투자자 입장에서의 정보의 유용성이 높아졌음을 확인하였다. 추가적인 횡단면 분석 결과, 테마감리 이전 연구개발비 자본화율이 높았던 기업일수록, 그리고 재무보고품질이 낮은 기업일수록 자본화율의 감소가 두드러지는 것으로 나타났다. 또한 연구개발비 회계처리를 자의적으로 활용할 유인이 강한 기업의 경우 테마감리 이전에는 기회주의적 회계처리 행태를 보였으나 테마감리 이후에는 그러한 행태가 나타나지 않아, 테마감리의 실효성에 대한 추가적인 증거를 제공하였다. 본 연구의 결과는 금융당국이 실시한 테마감리가 일정 부분 기대한 효과를 거두었다는 증거를 제시하였다는 점에서 의의가 있다. This study investigates whether and how bio-pharmaceutical firms’ R&D accounting and the value relevance of these firms’ R&D-related information have changed following the Financial Supervisory Service’s thematic audit review of the R&D accounting. Analyzing Korean listed firms for the period 2015-2019, we find that the R&D capitalization ratio of bio-pharmaceutical firms has been significantly reduced after the audit review. This effect takes place since 2017 when the Financial Supervisory Service released the advance notice regarding the thematic audit review and persists in 2018-2019 due to the release of the supervision guidance in 2018. Investigating changes in the value relevance of R&D information, we find that the value relevance of capitalized R&D expenditures has improved following the thematic review. In additional cross-sectional analyses, the results show that the effect of the audit review is more pronounced for firms with higher pre-audit review capitalization ratio and firms with lower financial reporting quality. We also show that while firms with strong incentives to use a discretion in R&D accounting used to opportunistically capitalize R&D expenditures, such behavior was no longer observed in the post-review period. Collectively, these findings suggest that despite the concern that the audit review would excessively limits firms’ discretion and flexibility in R&D accounting, the informativeness of R&D capitalization has increased.

The study shows the developmental tendency of toddler's verbal language during free choice activities time in childcare, which impacts on toddler's verbal language later on. Major outcomes of the study is as follows. Firstly, regarding development of grammar, the first part of speech that toddlers most frequently use is noun and following noun on the list are postposition, verb, pronoun, adverb, adjective, exclamation, determiner, and rhetoric. As for postposition, predicative postposition occurs most frequently, and nominative postposition, topical postposition, conjunctive postposition, adverbial postposition, complemental postposition, vocative postposition, and restrictive postposition are used in order. However, prenominal and objective postposition do not occur. In the case of pronoun, first person singular pronoun most frequently occurs, and it is followed by first person plural pronoun and second person singular pronoun. To further add to first person singular pronoun, what toddlers most frequently use is possessive, while they do not use third person pronoun or reflexive pronoun. Moreover, the result of development of argument structure shows that one-place predicate shows up most frequently, which followed by two-place predicate and three-place predicate. Regarding sentential type, declarative is most frequently used and interrogative and negative sentences are followed. Thirdly, the study also found that subject is more frequently omitted than other constituents of sentence. As for complex sentences, toddlers tend to use main clause and adverbial clause that expresses reason, condition, or intention.
