노현섭 ( Roh Hyun-sub ),김정찬 ( Kim Jung-chan ) 한국세무회계학회 2018 세무회계연구 Vol.0 No.56

본 연구는 지난 26년 동안 유효세율의 추세를 분석하였다. 본 연구는 기간경과에 따른 유효세율의 추세를 분석하기 위하여 1991년부터 2016년까지의 기간 동안 6,312 기업-연도표본을 조사하였다. 본 연구는 또한 국외원천소득이 있는 기업의 국내 및 국외원천 유효세율을 분석하였다. 분석결과는 유효세율이 유의하게 감소하였다는 것을 보여주고 있다. 유효세율의 감소는 다국적기업에만 집중되지 않았으며, 다국적기업과 내국기업 모두 대략 유사한 비율로 감소하였다. 다국적기업의 경우 국외원천 유효세율과 국내원천 유효세율 모두 감소하였다. 마지막으로, 기업특성의 변화는 유효세율의 전반적인 감소의 일부만을 설명하고 있다. 추가분석의 결과는 기업특성을 통제한 후에도 유효세율이 유의적으로 감소하였다는 분석결과를 발견하였다. 본 연구는 유효세율의 기간추세를 분석함으로써 조세회피 연구에 공헌한다. 또한, 본 연구는 유효세율의 결정요인 연구에 공한할 것이다. In this paper, we investigate the trend in corporate effective tax rates over the past 26 years. To investigate the existence of a trend in effective tax rates over time, we examine a sample of 6,312 firm-year from 1991 to 2016. We study the trend in effective tax rates. We also examine domestic and foreign effective tax rates, which we use to test domestic versus foreign rates for corporations that have income from foreign sources(multinational firms). The results show that the effective tax rates have decreased significantly.The decline in effective tax rates is not concentrated in multinational firms, effective tax rates have declined at approximately the similar rate for both multinational and domestic firms. Within multinational firms, both foreign and domestic effective tax rates have decreased. Finally, changes in firm characteristics explain little of the overall decrease in effective tax rates. The Result of additional analysis suggests, that even after controlling for firm characteristics, we continue to see a significant decrease in effective tax rates over time. This paper contributes to the literature by executing an examination of time trends in corporate effective tax rates. And, this study is important for researchers interested in studying the determinants of effective tax rates.

The purpose of this study is to see how a soccer player's performance orientation affects his/her self fulfillment. To this end, I analyzed 1) the relation between performance orientation and self fulfillment by taking into account sociodemographic characteristics and the effect of performance orientation on the degree of self fulfillment. Simple random sampling was performed to produce a sample of 250 players selected from those who registered with the K-League in 2002. 16 questionnaires deemed either untrustworthy or partially omitted were excluded, leaving 234 questionnaires for study. The questionnaire contained total 33 questions (i.e., 3 on general characteristics, 20 on performance orientation, and 9 on self fulfillment). Frequency analysis, t-test, Oneway-ANOVA, Scheffe test, correlation analysis and regression analysis were performed. The above methods and procedures produced the following results. First, training and order, which are sub-variables for performance orientation, had a statistically significant difference (5% range) regarding age while assignment orientation showed a statistically significant difference (5% range) with regard to education level. Second, goal realization, which is a sub-variable for self fulfillment, had a statistically significant difference (5% range) regarding age and education level. Thud, competence demonstration, which &d a significant effect on self orientation and training/order, showed 27.9%(R^(2)=.279) of explicability with regard to self fulfillment. Fourth, competence development, which had a significant effect on assignment orientation and training/order, resulted in 49.5%(R^(2)=.495) of explicability regarding self fulfillment. Fifth, goal realization, which had a significant effect on all variables including assignment orientation, self orientation and training/order, resulted in 40.2%(R^(2)=.402) of explicability regarding self fulfillment.

본 논문은 정치적 비용가설에 따라 기업규모와 유효세율간의 관계를 실증분석한다. 정치적 비용가설은 기업의 규모가 클수록 정치적 비용의 부담이 높다고 가정한다. 기업규모 변수로는 매출액이 사용되며, 정치적 비용 변수로는 유효세율 등이 사용된다. 유효세율에 대한 분석결과는 대기업의 유효세율이 소기업보다 낮은 것으로 나타나고 있으며, 정치적 비용가설과 일치하는 일관된 증거를 제시하지 못하고 있다. 대기업의 유효세율이 낮은 이유의 한 가지는 유효세율 이외의 정치적 비용의 부담이 높을 수 있으므로 조세공과부담률, 기부금부담률, 접대비부담률을 분석한다. 유효세율 이외의 정치적 비용의 분석결과는 정치적 비용가설과 일치하는 일관된 증거를 제시하지 못하고 있으나, 몇 가지 부담률과 몇 가지 기업군 분류의 부담률은 가설과 일치하고 있다.

A sub-1-volt nanoelectromechanical switching device.

Lee, Jeong Oen,Song, Yong-Ha,Kim, Min-Wu,Kang, Min-Ho,Oh, Jae-Sub,Yang, Hyun-Ho,Yoon, Jun-Bo Nature Pub. Group 2013 Nature nanotechnology Vol.8 No.1

<P>Nanoelectromechanical (NEM) switches have received widespread attention as promising candidates in the drive to surmount the physical limitations currently faced by complementary metal oxide semiconductor technology. The NEM switch has demonstrated superior characteristics including quasi-zero leakage behaviour, excellent density capability and operation in harsh environments. However, an unacceptably high operating voltage (4-20 V) has posed a major obstacle in the practical use of the NEM switch in low-power integrated circuits. To utilize the NEM switch widely as a core device component in ultralow power applications, the operation voltage needs to be reduced to 1 V or below. However, sub-1 V actuation has not yet been demonstrated because of fabrication difficulties and irreversible switching failure caused by surface adhesion. Here, we report the sub-1 V operation of a NEM switch through the introduction of a novel pipe clip device structure and an effective air gap fabrication technique. This achievement is primarily attributed to the incorporation of a 4-nm-thick air gap, which is the smallest reported so far for a NEM switch generated using a 'top-down' approach. Our structure and process can potentially be utilized in various nanogap-related applications, including NEM switch-based ultralow-power integrated circuits, NEM resonators, nanogap electrodes for scientific research and sensors.</P>

엄승섭(Eum, Seung-Sub),김현도(Kim, Hyun-Do),김동순(Kim, Dong-Soon) 한국경영교육학회 2021 경영교육연구 Vol.36 No.6

[연구목적] 본 연구에서는 기업의 사회적책임(CSR) 활동이 기업의 경영성과 및 기업가치에 미치는 영향을 실증분석하고, 그 시사점을 제공하고자 하였다. [연구방법] 본 연구는 기업의 사회적책임(CSR) 활동이 경영성과 및 기업가치에 미치는 영향에 대한 기존에 수행되었던 연구들과 논의를 충분히 검토하였고, 이를 바탕으로 4가지 가설을 도출하였다. 본 연구는 2011년~2014년까지 한국지배구조원에서 발표하고 있는 ESG점수를 사회적책임(CSR) 활동의 대용변수로 활용하여 실증분석을 실행하였다. [연구결과] 기업의 사회적책임(CSR) 활동이 경영성과 및 기업가치에 미치는 영향을 분석한 결과, 첫째, R&D 지출과 CSR 간에는 통계적으로 유의하게 양(+)의 관계가 나타났다. 둘째, CSR과 매출액 간에도 유의한 양(+)의 관계가 나타났다. 셋째, CSR과 수익성 (ROA, ROE) 간에는 유의한 음(-)의 관계가 나타났다. 넷째, CSR과 기업가치(Tobin’s Q, PBR)는 유의한 양(+)의 관계가 나타났다. [연구의 시사점] 기업의 사회적책임(CSR) 활동은 매출액에 대해서는 긍정적인 영향을 미치는 것으로 나타났으나, 수익성에는 부정적으로 작용하는 것으로 나타났다. 그러나 비록 수익성은 낮더라도 매출액 증가로 인하여 절대적인 수익 증가가 나타난다면 장기적으로 기업가치는 증대할 것으로 기대된다. 향후 이에 대한 추가연구가 필요할 것으로 판단된다. [Purpose] In this study, we aimed to provide suggestions by examining the impact of CSR activities on corporate performance and firm value. [Methodology] We conducted an empirical analysis using ESG scores published by the Korea Governance Service from 2011 to 2014 as a proxy for CSR activities. [Findings] We found the following empirical results. First, we found a positive and significant relation between R&D expenditures and CSR activities. Second, we found a positive and significant relation between CSR and sales. By contrast, the relation between CSR and profitability (ROA and ROE) was significantly negative. Fourth, we found a positive and significant association between CSR and firm value (Tobin’s Q and PBR). [Implications] Korean firms’ CSR activities were found to have a positive effect on sales, but negatively on profitability. However, even if short-term profitability is low, an increase in sales along with R&D expenditures can lead to an increase in long-term firm value.

High ft 30nm Triple-Gate In0.7GaAs HEMTs with Damage-Free SiO₂/SiNx Sidewall Process and BCB Planarization

Dae-Hyun Kim,Seong-Jin Yeon,Saegn-SUb Song,Jae-Hak Lee,Kwang-Seok Seo 대한전자공학회 2004 Journal of semiconductor technology and science Vol.4 No.2

A 30 nm In0.7GaAs High Electron Mobility Transistor (HEMT) with triple-gate has been successfully fabricated using the SiO₂/SiN, sidewall process and BCB planarization. The sidewall gate process was used to obtain finer lines, and the width of the initial line could be lessened to half by this process. To till the Schottky metal effectively to a narrow gate line after applying the developed sidewall process, the sputtered tungsten (W) metal was utilized instead of conventional e-beam evaporated metal. To reduce the parasitic capacitance through dielectric layers and the gate metal resistance (Rg), the etchedback BCB with a low dielectric constant was used as the supporting layer of a wide gate head, which also offered extremely low Rg of 1.7 Ohm for a total gate width (Wg) of 2X100 m. The fabricated 30nm In0.7GaAs HEMTs showed Vth of -0.4V, Gm,max, of 1.7S/mm, and f.r of 421GHz. These results indicate that InGaAs nano-HEMT with excellent device performance could be successfully fabricated through a reproducible and damage-free sidewall process without the aid of state-of-the-art lithography equipment. We also believe that the developed process will be directly applicable to the fabrication of deep sub-50nm InGaAs HEMTs if the initial line length can be reduced to below 50nm order.<br/> <br/>

Genome-wide transcriptome analysis of rice genes responsive to chilling stress

<P> Cho, H. Y., Hwang, S.-G., Kim, D. S. and Jang, C. S. 2012. Genome-wide transcriptome analysis of rice genes responsive to chilling stress. Can. J. Plant Sci. 92: 447-460. Low temperature is known to be one of the major challenges to rice production. We have selected chilling-tolerant TILLING of Donganbyeo, which showed significantly vigorous growth relative to wild-type plants under chilling stress conditions (10-12°C). We performed a comparative transcriptome analysis using a chilling-tolerant line and wild-type plant with the objective to evaluate genomic responses to chilling stress and to identify chilling inducible genes. Functional enrichment analysis results demonstrated that a large proportion of chilling-inducible genes were associated with certain biological pathways, e.g., monosaccharide catabolic processes, reflecting the energy requirements necessary for adaptation to sub-optimal temperatures in plants. Extremely low correlation coefficients in a range of −0.07 to 0.04 were detected between plant responses to chilling stress and different abiotic stress conditions such as drought, salt, cold, and heat; these results imply that plants might exploit strikingly different response mechanisms against stress conditions. The largest subnetwork, which was composed of 78 chilling-specific inducible genes, was found in the tolerant plants, but not in the wild-type plants, which probably implies the existence of a delicate and harmonious signaling pathway setup in the tolerant plants. Expression patterns of 20 chilling-responsive genes were assessed via abiotic stress treatments and phytohormone treatments. About 80% of the tested chilling-inducible genes were upregulated by exogenous abscisic acid (ABA) treatment. The results of this study may prove useful in elucidating the chilling-response pathway and in the development of chilling-tolerant rice varieties. </P>

2,4-bis (p-hydroxyphenyl)-2-butenal (HPB242) induces apoptosis via modulating E7 expression and inhibition of PI3K/Akt pathway in SiHa human cervical cancer cells.

Kim, Man Sub,Kim, Jung Hee,Bak, Yesol,Park, Yun Sun,Lee, Dong Hun,Kang, Jeong Woo,Shim, Jung-Hyun,Jeong, Heon Sang,Hong, Jin Tae,Yoon, Do Young Lawrence Erlbaum Associates, Publishers [etc.] 2012 Nutrition and cancer Vol.64 No.8

<P>The Maillard reaction is a chemical reaction occurring between an amino acid and a reducing sugar, usually requiring thermal processing. Maillard reaction products (MRPs) have antioxidant, antimutagenic, and antibacterial effects, and although 2,4-bis (p-hydroxyphenyl)-2-butenal (HPB242), a fructose-tyrosine MRP, appears to inhibit proliferation of cancer cells, its mechanism of action has not been studied in detail. We found that HPB242 treatment modulated expression of cyclins and tumor suppressor genes in SiHa human cervical cancer cell lines: cyclins and phospho-pRB were downregulated, whereas the expression of CDK inhibitors and p53 was enhanced. HPB242 induced apoptosis dose-dependently by suppressing E7 expression and leading to sub-G1 cell-cycle arrest in SiHa cell lines; treatment also led to the proteolytic cleavage of caspase-3, -9, and poly (ADP-ribose) polymerase. Moreover, HPB242 upregulated Fas expression, altered expressions of pro- and antiapoptotic factors, and also inhibited nuclear translocation of nuclear factor κB and phosphorylation of IκB. HPB242 treatment decreased phosphatidyl inositol-3 kinase and p-Akt expression levels, demonstrating that this survival pathway may also be inhibited by HPB242. Cumulatively, HPB242 promotes apoptosis by influencing E7 expression, inducing cell-cycle arrest at sub-G1 phase, and promoting both intrinsic (mitochondrial) and extrinsic (Fas-dependent) apoptosis in SiHa human cervical cancer cells.</P>
