Background and Objectives : In oriental Medicine, there is a concept that herb works only in it's own specific site called 'Guikyung(歸經)'. If two herbs have same effect and different Guikyung, two herbs would work at different site respectively. so we want to prove that whether Guikyung has significance or not in experimentally. Methods : In order to investigate the effects of Victicis Fructus & Bupleuri Radix on the Allergic rhinitis, BALB/c mouse was used. Control and experimental group 1, 2 were induced allergic rhinitis. Experimental group 1 was administered Victicis Fructus for 28 days and group 2 was administerd Bupleuri Radix for same period. WBC, neutrophil, lymphocyte, monocyte, IL-4 and $IFN-{\gamma}$ were measured and histological examination was performed. The statistical significance was examined by Independent Samples T test. Results : 1. WBC, neuoophil, lymphocyte, monocyte, IL-4 and $IFN-{\gamma}$ showed no statistically significant differences in three groups. 2. Histological examination had no differences in three groups. Conclusion: Victicis Fructus & Bupleuri Radix have no effect on allergic rhinitis and the reason is estimated that Guikymg plays a important roll to determine the effect of herb from the viewpoint of oriental medicine.

This paper empirically examines the effect of voluntary disclosure on accounting quality and firm value. As interest of ESG information grow, most firm tend to voluntarily provide non-financial information to the market. Under the absence of non-financial information disclosure standards, the concerns on undertandability and comparability of non-financial information increase. This paper examines whether a firm with good quality of financial information voluntarily disclosure non-financial information. In addition, we further test a relationship between non-financial disclosure and a firm’s value. Specifically, we measure non-financial information as whether a firm voluntarily disclosure a sustainability report. We also measure discretionary accruals as a proxy for financial information quality. For a proxy for a firm’s value, we employ a firm’s TobinQ and MTB, respectably. Using 11,450 listed-companies from 2016 to 2021, we find that the firms with good accounting information quality are more likely to disclosure a sustainability report. This implies a positive relationship between financial information and non-financial information in terms of quality. We also find that a firm disclosure a sustainability report are more likely to have high firm value. These findings suggest that voluntary disclosure affects a firm’s value. Our study contributes to better understanding a firm’ voluntary non-financial information and the effect of non-financial information on s firm’s value.

The Effect of Regulation Fair Disclosure on Conference Calls: The Case of Earnings Surprises

남혜정,백복현 한국증권학회 2009 Asia-Pacific Journal of Financial Studies Vol.38 No.6

While conference calls have been widely used as a communication tool between firms and investors, little research has examined the effect of this voluntary disclosure metric on analyst forecasts. In this paper, we examine whether firms use conference calls to guide down analysts’ earnings forecasts, thereby avoiding negative earnings surprises before and after Regulation FD. Our findings show that firms hosting conference calls are more likely to guide analysts’ forecasts downward and, as a result, they tend to successfully avoid negative earnings surprises in the pre Reg FD period. However, we do not find such relations in the post Reg FD period. We also find that the market reacts positively to firms hosting conference calls only in the post Reg FD period, consistent with the view that the market rewards a reduction in managers’ opportunistic guidance to meet the analysts’ earnings estimate.

Objective : The side effect of prolonged use of topical corticosteroids to skin is well-known. Moreover, resent studies have shown that prolonged use of systemic corticosteroids also negatively impacts skin barrier function. Corticosteroids have a major role in the practical management of many variable conditions. So, it is important to find the drug or the method which could protect the skin from the damage caused by corticosteroids. At former study, we investigated that Insamyangyoung-tang has some effect on skin barrier function of DNCB induced contact dermatitis hairless mice. So, this study was performed to research the effect of Insamyangyoung-tang on the TEWL with high dose steroid injected hairless mice. Method : Hairless mice were divided into 4 groups ; Control group, Group A, Group B and Group C. All groups were injected triamcinolone O.4mg for 10 times. Control group was medicated distilled water during the experimental period. Group A was medicated distilled water for 5 days before the $1^{st}$ injection day, and then medicated Insamyangyoung-tang extract during the experimental period. Group B was medicated Insamyangyoung-tang extract for 5 days before the $1^{st}$ injection day, and then medicated distilled water during the experimental period. Group C was medicated Insamyangyoung-tang extract for 5 days before the $1^{st}$ injection day, and then medicated Insamyangyoung-tang extract during the experimental period. TEWL of each group was measured for 5 times. After the $10^{th}$ injection, the tissue sample was made and the damage of epithelial cell was examined. Statistical significance was set at p<0.05 by using non parametric methods and repeated-anova.. Results : Group C showed significant effect on TEWL change of hairless mice evoked by triamcinolone injection. Group A and Group B also showed some effect, but there was no statistical significance.

성과중심의 재정운영을 위한 성과관리체계와 예산분류체계에 대한 연구 : 도로보수를 중심으로

남혜정 한국회계학회 2020 회계저널 Vol.29 No.1

This study examines the relationship between financial performance goal management system and budget classification. Financial performance goal management system was adopted to enhance financial responsibility of government financial programs and to make budget process more performance-oriented in the National Assembly. Since accruals accounting implemented in 2010, infrastructures are estimated and managed as an asset without depreciation. However, infrastructures are getting older and deterioration rate rapidly increases. This paper investigates the linkage between performance indicators and budget classification on road management. To do this, we review budgetary document, written settlement of accounts concerning revenue and expenditure, and performance report, together. This paper finds that the linkage between performance indicators and budget classification on road management weak. In the budgetary document, road repair is consist of road maintenance and functional improvement of road construction. However, these classifications do not match with performance indicators. This paper further reviews the financial statement of Ministry of Land, Infrastructure and Transport. They provide information about road pavement condition index, but not maintenance expenditure depending on road management. Based on the analysis, we suggest the four considerations to improve the linkage between performance indicator and budget classification. First, developing relevant performance indicators. Second, judgement based on asset management system. Third, accessibility to accounting information about road management, Four, improve usability of road management information. 우리나라 도로의 노후화가 급속하게 진행되고 있으나, 도로관리에 대한 통합적이고체계적인 자산관리에 대한 논의는 활발하지 않다. 특히 성과중심의 재정운영을 위한 다각적인 노력에도 불구하고, 집행예산에 대한 설명책임(accountability)은 여전히 낮은 편이다. 우리나라는 책임성있는 예산집행과 성과중심의 재정운영을 위하여 성과계획서, 프로그램예산, 발생주의 회계제도 등을 운영하고 있으며, 성과계획서의 성과지표를 통하여 효과적인 예산집행을 유도하고 있다. 본 연구는 핵심평가사업 중에 하나인 도로관리를 중심으로성과관리체계와 예산분류체계간의 연계성을 살펴보고, 국토부의 도로관리현황을 통하여 성과지표가 도로관리활동을 적절하게 반영하고 있는지 살펴보았다. 이를 위하여 국토교통부의 도로관리 중 도로보수를 중심으로 예산서, 결산서, 성과계획서를 검토하고, 각 보고서를바탕으로 성과중심의 재정운영이 이루어지고 있는지 살펴보았다. 이와 함께 미국, 캐나다, 일본의 도로관리관련 성과관리현황을 검토하고 이를 바탕으로 다음과 같은 개선방안을 제시하였다. 첫째, 도로관리사업의 성과중심의 재정운영을 위해서는 성과지표의 적절성 제고해야 한다. 둘째, 자산관리시스템하에서 유지보수가 판단되어야 한다. 셋째, 도로관리에 대한 회계정보 접근성을 제고해야 한다. 넷째, 도로관리정보의 활용성을 제고할 필요가 있다.

YB-301(an ointment including Hominis placenta) showed statistically no significant effect on skin erythema(p<0.05). conclusions : YB-301(an ointment including Hominis placenta) was effective m skin melanin, skin pH, skin humidity, transepidermal water loss in our study, so we suggest that Hominis placenta can be used as a ointment ingredient for strengthening the function of skin barrier.

기업의 ESG활동과 배당의사결정에 대한 연구

남혜정,김현정 한국공인회계사회 2021 회계·세무와 감사 연구 Vol.63 No.2

This study empirically examines the relationship between ESG performance and dividend payout decision using ESG ratings that represent the sustainability of the Korean firms’. Specifically, this paper explores the effect of ESG performance on dividend payout policy. As the interest of ESG is growing, the concern on stakeholders capitalism increases. Under the ESG, the firm needs to pay attention to various interested parties, not focus on the stakeholder’s wealth. Therefore, the relationship ESG performance and dividend payout policy is an empirical issue. To test the effect of ESG performance on dividend payout policy, we use 4,753 firm-year samples with E SG g rades among n on-financial i ndustries l isted on t he s ecurities market a nd K OSDAQ market which fiscal year ends in December from 2011 to 2018. We conduct a regression analysis to test the hypothesis. As a result of hypothesis 1 which confirms the relationship between ESG grade indicating E SG p erformance a nd d ividend payout p olicy show a s ignificant p ositive (+) relationship. In a ddition a s a result of the impact of ESG’s individual grade, the environmental grade ‘E’, the social value grade ‘S’ and the governance grade ‘G’, on dividend decision policy and found that each grade also has a significant influence on dividend decision policy. Furthermore, we find through Vuong test that E(environment) grade has a distinctly significant effect on ESG total grade. While prior studies have suggested that E and G grade have additional effects on ESG’s relationship to corporate value(Leem Wook Bin, 2019; Oh, Sang-hui and Lee, Seung-Tae 2019), this study shows that E is a statistically significant factor in dividend decision making. The findings of this study are expected to provide the following contributions: First, it is expected to contribute to the expansion of ESG related research. In recent years, empirical studies on ESG have been conducted but research on domestic companies(South Korea) are minimal. As the interest in sustainability and social responsibility of the enterprise is increasing, it would be meaningful to examines the impact of E SG a ctivities on t he d ecision making. In p articular, d ividend decision-making can be s een as p art of ESG activities in that it allocates corporate performance, but it may be desirable to allocate resources to stakeholder capitalism in terms of social contribution. The results of this study suggest that ESG performance is also affecting dividend policies and that ESG’s consideration is needed to establish future dividend policies and improve the system. Furthermore, the results of this study are expected to provide investors, regulators and policy-makers as well as relevant researchers in academia with beneficial implications for ESG and dividend payout decision. 본 연구는 기업의 지속가능성을 나타내는 ESG 등급을 이용하여 ESG 성과와 배당의사결정과의 관계를 살펴보았다. 2011년부터 2018년까지 유가증권시장 및 코스닥시장에 상장된 12월 결산법인 비금융업 중 ESG 등급이 있는 기업을 대상으로, ESG 성과와 배당의사결정과의 관계를 실증분석하였다. 분석결과 E SG 성과를 나타내는 E SG 등급은 배당의사결정에 유의한 양(+)의 관련성을 가지는 것으로나타났다. 또한 ESG의 개별항목별로 배당의사결정에 미치는 영향을 살펴보았으며, 각 항목들도 유의적인 영향을 미치고 있음을 발견하였다. 이와 함께, Vuong test를 통하여 E(환경)항목이 ESG 통합등급과는 차별적으로 유의적인 영향을 미치고 있음을 파악하였다. 본 연구는 ESG에 대한 사회적 관심이 높아지고 있는 상황에서 기업의 배당의사결정에 ESG 성과가미치는 영향을 실증적으로 분석하였다는 점에서 의의가 있다.

경영자의 과신성향이 세무위험에 미치는 영향

남혜정 한국세무사회 부설 한국조세연구소 2019 세무와 회계 연구 Vol.8 No.1

This study examine the effect of managers propensity on business decisions. Specifically, we investigate the effect of managers’ overconfidence on tax uncertainty. Prior studies examined the relationship between CEOs overconfidence and tax avoidance, but found mixed results. Tax avoidance is a short term decision in tax strategy rather than long term strategy. However, CEOs propensity does not changed over time. By considering the characteristics of CEO overconfidence into the tax decision, this paper explores the effect of CEO overconfidence and tax uncertainty. According to prior studies, CEO with overconfidence is more likely to overestimate the benefits from tax avoidance. But, he(she) tends to underestimate the risk from aggressive tax strategies and non-tax cost from tax avoidance. This decision leads to unstable tax policy and results in high volatile tax costs. Therefore, firms with overconfident CEO are more likely to have higher tax uncertainty. Using the behavior on repurchase treasury stock in Korea Stock Market, this paper find that the firms with CEOs overconfidence are more likely to have greater tax uncertainty. We further examine the effect of CEOs power on this relationship. We find that CEOs share ratio positively affects the relationship between CEOs overconfidence and tax uncertainty. This finding provides the empirical evidence on tax uncertainty and implications to related studies. 본 연구는 경영자의 성향이 주요 의사결정에 영향을 미치고 있다는 선행연구결과들을 바탕으로 세무의사결정에 미치는 영향을 살펴보고자 한다. 구체적으로 경영자의 과신성향이 세무위험에 영향을 미치는지 분석하였다. 경영자의 과신성향과 조세회피와의 관계를 살펴본 국내 선행연구들은 혼재된 결과를 제시하고 있다. 이는 경영자의 과신성향은 쉽게 변하지 않는 특성을 가진 반면에 조세회피는 세금최소화관점에서 측정된 단기적 변수이기 때문일 것이다. 또한 경영자의 특성이 세무의사결정에 미치는 영향을 살펴보기 위해서는 조세회피측면뿐만 아니라 기업가치 측면에서 세금 및 비세금비용의 증가를 고려한 세무전략관점에서 살펴보아야 한다. 따라서 과신성향의 경영자가 세무의사결정에 미치는 영향을 살펴보는데, 단기적인 조세회피보다는 세무위험관점에서 분석하는 것이 적절할 것이다. 본 연구는 경영자의 과신성향이 세무의사결정에 미치는 영향을 살펴보기 위하여 단기적인 조세회피가 아닌 세무위험과의 관계를 검증하고자 한다. 과신성향이 있는 경영자는 기업의 주요의사결정에 있어 합리적인 판단을 하기 보다는 비논리적이거나 낙관적인 판단을 하는 것으로 보고되었다. 또한 조세회피에 적극적인 반면에 조세회피로 인한 과세관청과의 분쟁발생 가능성을 과소평가하고 조세회피로부터 발생할 수 있는 비세금비용을 낮게 평가할 여지가 있다. 이로 인하여 세무의사결정에 있어서도 일관된 정책을 보여주지 못할 것으로 예상된다. 결과적으로 경영자의 과신성향이 높을수록 기업의 세무변동성은 확대되고, 나아가 세무위험이 높아질 것이다. 본 연구는 자사주매입행태를 이용하여 경영자의 과신성향을 측정하였으며, 세무위험은 과거 5년간의 연도별 유효세율에 대한 표준편차로 측정하였다. 2002년부터 2015년까지 유가증권시장에 상장된 기업을 대상으로 분석한 결과, 경영자의 과신성향이 있는 기업일수록 세무위험이 유의적으로 높음을 발견하였다. 또한 경영자의 지분율이 높을수록 과신성향과 세무위험 간의 양(+)의 관계가 더욱 강화됨을 발견하였다. 이러한 결과는 조세회피변수를 통제한 후에도 일관되게 나타났다. 본 연구의 결과는 세무위험에 영향을 미치는 변수로 경영자의 과신성향을 제시하였다는 점에서 의의가 있다.
