기업에 대한 법률자문에 있어 이익충돌의 문제

김연미 홍익대학교 2007 홍익법학 Vol.8 No.3

변호사윤리에 있어 “쌍방대리금지”의 원칙은 분명한 당사자 대립구조를 가지는 소송사건을 염두에 두고 만들어진 것으로,소송의 경우와 같은 적대적인 상대방이 존재하지 않는 경우가 많고 계쟁물의 범위도 분명하지 않은 송무 영역이 아닌 법률자문의 경우에는 그대로 적용하기 어렵다. 법률서비스의 수요 및 공급의 변화에 따라 송무 이외의 법률서비스가 점점 확대되고 있는데, 이러한 법률서비스의 경우 그 내용에 맞는 별도의 규정을 제정하여 이익충돌을 규제하는 것이 상당하다. 2004년 영국에서는 기업인수합병(M&A)에 있어서 인수대상회사가 인수 컨소시엄을 대리하는 로펌에 대하여 이익충돌을 이유로 법률자문금지 가처분(injunction) 결정이 나온 사례가 있었는데,업계에 큰 파장을 일으켰으며, 이후 영국에서는 주로 비송무 법률서비스를 제공하는 Solicitor들을 중심으로 이익충돌회피의 무와 기밀유지의무에 대한 규정을 현실에 맞게 개정하여야 한다는 요구가 있었고 이에 따라 윤리강령이 개정되었다. 이 글에서는 위 법률지문금지 가처분 사건의 내용과 그 이후 개정된 영국의 Solicitor들에 대한 윤리강령의 대응방식을 살펴본 후, 우리의 변호사법과 변호사 윤리강령 및 윤리규칙의 해석에 있어 시사하는 바를 검토한다. 우리 법조윤리에서도 송무 이외의 법률서비스의 제공에서 의뢰인의 이익 보호는 중요한 법익이지만, 영국의 Solicitor 윤리강령과 같이 비송무사건에 대한 현실적인 별도의 규제를 마련하는 것이 바람직할 수 있으며,비송무사건에서의 이익충돌 상황을 합리적으로 규제하려면 송무 이외의 법률서비스의 본질에 대한 검토와 이해가 필요하다. More debates have been made regarding conflict of interest in legal profession as the legal market has gone through dramatic changes. The current regulations addressing conflict of interest, which are set in the Lawyers Act and the Code of Ethics by the Korean Bar Association, assumes adversary structure for every case for which a lawyer is retained. In reality, however, such adversary structure cannot be found in most legal advices not associated with litigation. Applying the same regulation on legal services related to litigation and not related to litigation might lead to results unacceptable in actual situation. There is a recent case in England where the conflict of interest issue was hotly debated. In that case, the court granted an injunction against a lawfirm prohibiting provision of legal advices to the acquirer in takeover situation where the lawfirm had given certain advices to the target company regarding its key business line. This article reviews and analyzes this case as well as the reaction taken by the Law Society of England and Wales. This article also analyzes the case in Korean perspective and discusses the necessity of a separate regulation covering conflict of interest issue for legal services in non-litigation context.

We have compared the mathematics curriculum for K-12 between US and Korea. There is a big difference even within US curriculums depending whether it follows traditional curriculum or NCTM standards based. US traditional curriculum can be characterized as spiral, broad, standard algorithm based, requires a lot of practice and skills. NCTM Standard based curriculums can be characterized as spiral, broader, wants students to invent their own algorithm. Korean math curriculum is more traditional- linear, topic centered, standard algorithm based, and concept focused.

This study was performed to evaluate the tensile bond strength and modulus of elasticity of three permanent soft denture liners (Molloplast $B^{(R)}$, Ufi Gel $C^{(R)},\;Tokuyama^{(R)}$) before and after thermocycling. And their water sorption were also evaluated. Each soft denture liner was bonded to PMMA denture base resin blocks and the tensile bond strength and modulus of elasticity were measured by using universal testing machine. For the water sorption, weight measured after immersion of sea denture liners in $37{\pm}1^{\circ}C$ water bath for 4 weeks. The results were as follows : 1. Molloplast $B^{(R)}$ had the highest tensile bond strength, while Tokuyama had the lowest tensile bond strength. There was no significant difference between $Tokuyama^{(R)}$ and Molloplast $B^{(R)}$ in the both nonthermocycling and thermocycling. There was significant difference in tensile strength of $Tokuyama^{(R)}$ before and after thermocycling(p<0.05). 2. For the modulus of elasticity, there was no significant difference between Ufi Gel $C^{(R)}\;and\;Tokuyama^{(R)}$ in the both nonthermocycling and thermocycling. There was significant difference in modulus of elasticity of $Tokuyama^{(R)}$ before and after thermocycling(p<0.05). 3 The failure modes of Molloplast $B^{(R)}$ and Ufi Gel $C^{(R)}$ were mainley adhesive type and that of $Tokuyama^{(R)}$ was mainly mixed type in case of nonthermocycling and cohesive type after thermocycling. 4. The water sorption of each soft liners was within ${\pm}2%$ in times (p<0.05) but. there was no significant difference among the soft liners in times.

We prove the Carleman inequality for the Laplace operator on the Lorenz space and using that show strong unique continuation property holds for the Schr dinger operator when the lower order coefficients belong to the weak Lorenz space. This gives stronger estimate than the usual L?? norm estimates.

Mathematical visualization is a process to make mathematical images and use the image toward discovery and understanding. Hence, it is not proposed to make visual materials simply, but it has to have a circumstance that explores to visual object. In mathematics education, visualization has been ignored for a long time because people got used to manufacturing number or simbols. Therefore LOGO is a useful program that makes mathematical visualizaion possible for students. The purpose of this study is an application of LOGO program into geometry education through the mathematical visualization.

Statement of problem: The adhesion between titanium and ceramic is less optimal than conventional metal-ceramic bonding, due to reaction layer form on cast titanium surface during porcelain firing. Purpose: This study characterized the effect of titanium-ceramic adhesion after gold and TiN coating on cast and wrought titanium substrates. Material and method: Six groups of ASTM grade II commercially pure titanium and cast titanium specimens$(13mm{\times}13mm{\times}1mm)$ were prepared(n=8). The conventional Au-Pd-In alloy served as the control. All specimens were sandblasted with $110{\mu}m\;Al_2O_3$ particles and ultrasonically cleaned for 5min in deionized water and dried in air before porcelain firing. An ultra-low-fusing dental porcelain (Vita Titankeramik) was fused on titanium surfaces. Porcelain was debonded by a biaxial flexure test at a cross head speed of 0.25mm/min. The excellent titanium-ceramic adherence was exhibited by the presence of a dentin porcelain layer on the specimen surface after the biaxial flexure test. Area fraction of adherent porcelain (AFAP) was determined by SEM/EDS. Numerical results were statistically analyzed by one-way ANOVA and Student-Newman-Keuls test at ${\alpha}=0.05$. Results: The AFAP value of cast titanium was greatest in the group 2 with TiN coating, followed by group 1 with Au coating and the group 3 with $Al_2O_3$ sandblasting. Significant statistical difference was found between the group 1, 2 and the group 3 (p<.05). The AFAP value of wrought titanium was greatest in the group 5 with TiN coating, followed by the group 4 with Au coating and the group 6 with $Al_2O_3$ sandblasting. Conclusion: No significant difference was observed among the three groups (p>.05). The AFAP values of the cast titanium and the wrought titanium were similar. However the group treated with $Al_2O_3$ sandblasting showed significantly lower value (p<.05).

구치직립교정에 대한 증례보고

김연미 광주보건대학 2001 論文集 Vol.26 No.-

Loss of posterior teeth, usually first permanent molars, is a frequent problem in adults, When a posterior tooth is lost, the adjacent teeth usually tip, drift, and rotate. As the teeth move, the adjacent gingival tissue becomes folded and distorted, forming a plaque-harboring pseudopocket that may be virtually impossible for the patient to clean. The elimination of potentially pathologic conditions associated with tipped molars is probably the most important procedure in adjunctive orthodontics and has the added advantage of simplifying the ultimate restorative procedures. This report describers two cases of molar uprighting using helical spring&open coil spring.

This study is a single group quasi-experimental study to explore the effects of simulation-based learning for postpartum hemorrhage care on nursing college students' critical thinking tendency, communication confidence, and problem-solving process. The study was conducted on 86 nursing college students in G-province through structured survey tools from February 26 to April 27, 2018. Data analysis was conducted paired t-test, and correlation using SPSS WIN 21.0 program. Critical thinking tendency, communication confidence, and problem-solving process of respondents all increased after simulation-based learning, but among them, only critical thinking tendency was statistically significant (t=2.186, p=.030). There were positive correlations among variables; critical thinking tendency and communication confidence (r=.623, p<.001), critical thinking tendency and problem-solving process (r=.554, p<.001), communication confidence and problem-solving process (r=.535, p<.001). The simulated-based learning for postpartum hemorrhage care is regarded to improve nursing college students' critical thinking tendency. This result suggests that critical thinking tendency that was improved through simulation-based learning could be related to improving communication confidence and problem-solving process. Therefore, simulation-based learning contribute to improving the clinical adaptation and emergency response capabilities of the nursing college students. For maintaining the effective education for nursing college students, it is necessary to carry out the advanced and integrated operations in nursing simulation-based education through continuous research. 본 연구는 산후출혈간호 시뮬레이션 교육이 간호대학생의 비판적사고 성향, 의사소통 자신감, 문제해결과정에 대해 미치는 영향을 알아보고자 실시한 단일군 전후 설계 유사실험연구이다. 연구대상자는 G지역 간호학과 4학년 86명으로, 2018년 2월 26일부터 4월 27일까지 구조화된 설문도구를 통해 시뮬레이션 교육 전후 비판적사고 성향, 의사소통 자신감, 문제해결과정을 확인하였다. SPSS/WIN 21.0 프로그램을 이용하여 paired t-test, pearsons correlation을 확인하여 자료를 분석하였다. 연구결과, 대상자의 시뮬레이션 학습 후 비판적사고 성향, 의사소통 자신감, 문제해결과정은 모두 상승하였으나, 비판적 사고 성향에서만 통계적 유의한 차이를 보였다(t=2.186, p=.030). 비판적 사고 성향과 의사소통 자신감(r=.623, p<.001), 비판적 사고 성향과 문제해결과정 (r=.554, p<.001), 의사소통 자신감과 문제해결과정(r=.535, p<.001) 등 모든 변수들은 각각 양의 상관관계를 보여, 비판적 사고 성향의 향상이 다양하고 복잡한 임상 현장에서 문제 해결 및 의사 결정을 내리는 능력과도 관련이 있음을 확인하였다. 즉, 시뮬레이션 기반 교육이 간호학생들의 비판적 사고 능력의 향상을 도모하고 그와 관련된 임상적응과 응급대처능력 향상에 기여하리라 기대된다. 또한 더욱 효과적인 교육을 위해 최신 지견을 접목한 산학연구 및 발전적인 통합간호 시뮬레이션의 지속적인 운영이 필요하다고 생각한다.
