주주보호를 심각하게 고려하는가?: 미국과 독일의 기업지배구조

Baum & Scott,서정 譯 한국증권법학회 2007 증권법연구 Vol.8 No.1

The paper undertakes a comparative study of the set of laws affecting corporate governance in the United States and Germany, and an evaluation of their design - if one assumes that their objective were the protection of the interests of minority outside shareholders. The rationale for such an objective is reviewed, in terms of agency cost theory, and then the institutions that serve to bound agency costs are examined and critiqued. In particular, there is discussion of the applicable legal rules in each country, the role of the board of directors, the functioning of the market for corporate control, and (briefly) the use of incentive compensation. The paper concludes with the authorsviews on what taking shareholder protection seriously, in each country legal system, would require.

Injection of Botulinum Toxin for Preventing Salivary Gland Toxicity after PSMA Radioligand Therapy: an Empirical Proof of a Promising Concept

Baum, Richard P.,Langbein, Thomas,Singh, Aviral,Shahinfar, Mostafa,Schuchardt, Christiane,Volk, Gerd Fabian,Kulkarni, Harshad 대한핵의학회 2018 핵의학 분자영상 Vol.52 No.1

The dose-limiting salivary gland toxicity of $^{225}Ac$-labelled PSMA for treatment of metastatic, castration-resistant prostate cancer remains unresolved. Suppressing the metabolism of the gland by intraparenchymal injections of botulinum toxin appears to be a promising method to reduce off-target uptake. A $^{68}Ga-PSMA$ PET/CT scan performed 45 days after injection of 80 units of botulinum toxin A into the right parotid gland in a 63-year-old patient showed a decrease in the SUVmean in the right parotid gland of up to 64% as compared with baseline. This approach could be a significant breakthrough for radioprotection of the salivary glands during PSMA radioligand therapy.

Systemic Endoradiotherapy with Carrier-Added 4-[$^{131}I$] Iodo-L-Phenylalanine: Clinical Proof-of-Principle in Refractory Glioma

Baum, Richard P.,Kluge, Andreas,Gildehaus, Franz Josef,Bronzel, Marcus,Schmidt, Karl,Schuchardt, Christiane,Senftleben, Stephan,Samnick, Samuel The Korea Society of Nuclear Medicine 2011 핵의학 분자영상 Vol.45 No.4

Purpose To explore feasibility, tolerability, dosimetry and probable efficacy of intravenous endoradiotherapy with carrier-added 4-[$^{131}I$]iodo-L-phenylalanine (c.a. $^{131}I$-IPA) in refractory high-grade glioma. Methods Two male patients (45 and 50 years), with longstanding, extensively pre-treated gliomas and evidence of progression underwent single intravenous injections of 2 and 4 GBq of c.a. $^{131}I$-IPA, respectively. Tumour targeting was verified by $^{131}I$-IPA single-photon emission computed tomography (SPECT). Metabolic and morphological changes indicative of tumour response were assessed by sequential [$^{18}F$] fluoroethyltyrosine ($^{18}F$-FET) positron emission tomography (PET) and contrast-enhanced magnetic resonance imaging (MRI) following therapy. Further monitoring included clinical state, safety laboratory, quality of life and dosimetry. Absorbed mean organ and whole-body doses were determined according to the Medical Internal Radiation Dose (MIRD) scheme using OLINDAEXM based on serial planar scintigraphy. Results Both patients tolerated the treatment well. No evidence of acute or delayed organ toxicity was observed. $^{131}I$-IPA accumulated in the tumour recurrences identified by MRI/$^{18}F$-FET. In patient 1, PET showed progressively decreasing maximum standardised uptake values ($SUV_{max}$) over 10 months, indicating metabolic response, paralleled by reduced contrast enhancement and tumour volume on MRI. Progression occurred 18 months after therapy. Treatment was repeated using 6.6 GBq of $^{131}I$-IPA, to which no response was observed. Patient 2, followed-up for 3 months after therapy, showed stable disease on MRI and PET. Mean absorbed whole body doses ranged from 0.13 to 0.17 mSv/MBq, with the highest absorbed organ doses to kidneys, bladder and heart (0.86-1.23; 0.49-0.6 and 0.45-0.56 mSv/MBq). Conclusion Systemic endoradiotherapy using up to 6.6 GBq of c.a.$^{131}I$-IPA is not associated with clinically detectable toxicity. Measurable anti-tumour effects in gliomas were observed. $^{131}I$-IPA warrants further evaluation as glioma therapy.

Detecting solar chameleons through radiation pressure

Baum, S.,Cantatore, G.,Hoffmann, D.H.H.,Karuza, M.,Semertzidis, Y.K.,Upadhye, A.,Zioutas, K. Elsevier 2014 Physics letters: B Vol.739 No.-

<P><B>Abstract</B></P> <P>Light scalar fields can drive the accelerated expansion of the universe. Hence, they are obvious dark energy candidates. To make such models compatible with tests of General Relativity in the solar system and “fifth force” searches on Earth, one needs to screen them. One possibility is the so-called “chameleon” mechanism, which renders an effective mass depending on the local matter density. If chameleon particles exist, they can be produced in the sun and detected on Earth exploiting the equivalent of a radiation pressure. Since their effective mass scales with the local matter density, chameleons can be reflected by a dense medium if their effective mass becomes greater than their total energy. Thus, under appropriate conditions, a flux of solar chameleons may be sensed by detecting the total instantaneous momentum transferred to a suitable opto-mechanical force/pressure sensor. We calculate the solar chameleon spectrum and the reach in the chameleon parameter space of an experiment using the preliminary results from a force/pressure sensor, currently under development at INFN Trieste, to be mounted in the focal plane of one of the X-Ray telescopes of the CAST experiment at CERN. We show, that such an experiment signifies a pioneering effort probing uncharted chameleon parameter space.</P>

판매자-구매자 2자간 협상에 있어서 협상력 및 학습에 관한 연구

방석범(Suk Baum Pahng) 한국경영학회 1992 經營學硏究 Vol.22 No.1

본 연구는 행동과학에 있어서 협상과정에 관한 두가지 대표적인 접근방법, 즉 협상을 협상자간 전술적행위의 전개과정(process of tactical action)으로 보는 견해와 협상자의 학습과정(process of learning)으로 보는 견해를 결합함으로써 협상과정에 대한 좀 더 포괄적인 시각을 제공하는데 그 목적을 두었다. 이 결합된 접근방법은 협상을 두 협상자가 전술적행위의 교환을 통하여 서로의 상대적인 협상력을 이해하여 가는 학습과정으로 묘사하였다. 결합된 협상모델로부터 다섯개의 가설이 유도되었으며 판매자-구매자간의 판매가격을 결정하는 협상상황에 적용되어 검증되었다. 검증결과에 따르면 협상력이 강한 협상자일수록 양보를 적게하고 보다 강한 전술적행위를 선택하는 경향을 보였으며, 그리고 이러한 강압적인 전술적행위들이 상대방의 협상력에 대한 학습을 더 효율적으로 촉진시키는 것으로 나타났다.

Slowing at Sunset: Administrative Procedures and the Pace of Reform in Korea

Jeeyang Rhee Baum,Kathleen Bawn 동아시아연구원 2011 Journal of East Asian Studies Vol.11 No.2

Overhaul of administrative procedures is an important part of most democratic transitions, and procedural regularization and transparency are often seen as steps toward the consolidation of democracy. Administrative procedures affect policy decisions, but whether particular procedural reforms facilitate or hinder democratic responsiveness depends on the details of the procedure and the political environment. In this article, we examine a particular procedural reform: the adoption of a sunset provision in Korea as part of an omnibus administrative procedures package at the end of Kim Young Sam’s presidency. A sunset provision might be seen as clearly promoting democratic responsiveness by requiring the winner of the most recent election to explicitly decide whether to keep or drop old rules and regulations. Alternatively, it might be seen as limiting a democratically elected leader’s ability to change policy in accordance with his mandate, by requiring expenditure of effort and resources just to maintain a status quo. We argue that the second interpretation applies to the Korean case. We use a spatial model and evidence from regulatory decisionmaking to argue that Kim Young Sam favored the sunset provision because it would constrain the policy decisions of future presidents. Our model offers an explanation for why Kim Young Sam would propose a sunset provision that limited the life of his own regulations.

Breaking Authoritarian Bonds: The Political Origins of the Taiwan Administrative Procedure Act

Jeeyang Rhee Baum 동아시아연구원 2005 Journal of East Asian Studies Vol.5 No.3

Taiwan recently adopted a series of administrative reform laws designed to make the bureaucracy more transparent and allow public participation in regulatory policies. Because administrative reform limits the executive’s power, it is clear why legislatures would favor strict administrative procedures. But it is less clear why presidents would support them. The passage of these laws begs the question why presidents support administrative procedural reforms designed to slow down and impose extra costs on the implementation of their policies? I argue that in Taiwan, President Lee Teng-hui’s control of his party deteriorated as factional disputes within his own party increased over time. Lee ultimately concluded that the KMT’s political survival depended on major reforms. Consequently, the status-quo-oriented bureaucracy – hitherto an important source of support for Lee and his key constituencies – became an impediment. Lee supported Taiwan’s APA in order to reduce the bureaucracy’s capacity to impede reform. More generally, I argue that administrative procedures designed to open up the bureaucracy to the public, including previously excluded groups, can serve politicians’ goal of redirecting the bureaucracy. Archival data, secondary sources, and interviews with key presidential advisors, senior career bureaucrats, and politicians support my argument.
