억제 유전자를 포함치 않은 효모의 절제회복 관여 RAD4 유전자의 분리

김재범,박상대,최인순,전성호 한국유전학회 1990 Genes & Genomics Vol.12 No.2

The RAD4 gene of Saccharomyces cerevisiae is absolutely required for the incision step of UV-induced nucleotide excision repair. The previsously cloned RAD4 gene by phenotypic complementation of UV-sensitive rad 4-4 mutants with a yeast genomic library (pPC1) appeared to localize in the right arm of chromosome V as determined by rapid chromosome mapping. This cloned RAD4 gene did not contain a suppressor gene as determined by suppression test of various auxotrophic mutants containing nonsense mutations. In addition, all different plasmids harboring the cloned yeast DNA inserts conferred UV resistance to rad 4-4 mutants to a similar level regardless of their copy number. These results indicated that the pPC1 is a truly functional RAD4 gene and its complementing activity must be resulted from the yeast RAD4 gene.

ALD법으로 제조된 Al₂O₃ 박막의 물리적 특성

$Al_2O_3$ is a promising gate dielectric because of its high dielectric constant, high resistivity and low leakage current. Since $OH^-$ radical in $Al_2O_3$ films deposited by ALD using TMA and $H_2O$ degrades the good properties of $Al_2O_3$, TMA and $O_3$ were used to deposite $Al_2O_3$ films and the effects of $O_3$ on the properties of the $Al_2O_3$ films were investigated. The growth rate of the $Al_2O_3$ film under the optimum condition was 0.85 $\AA$/cycle. According to the XPS analysis results the $OH^-$ concentration in the $Al_2O_3$ film deposited using $O_3$ is lower than that using $H_2O$. RBS analysis results indicate the chemical formula of the film is $Al_{2.2}O_{2.8}$. The carbon concentration in the film detected by AES is under 1 at%. SEM observation confirms that the step coverage of the $Al_2O_3$ film deposited by ALD using $O_3$ is nearly 100%.

회사지배구조 관련 회사법제의 나아갈 방향 - 2008년 상법개정안 검토 -

김재범 한국경영법률학회 2008 經營法律 Vol.19 No.1

The bill on amendment to commercial law has been proposed for consideration on May 7th, 2008. It has several clauses about the reform of corporate governance in corporate law like as the introduction of executive officer, corporate opportunity doctrine, electronic voting system, and the extension of director's self dealing transaction. Those clauses have been hotly debated until now and have not come to an agreement yet. In this essay I try to analyze the each different points of opposing views and to conclude which point of the views would be the more resonable. First, I come to reach the conclusion that the electronic voting(section 368 4) has little effect on the discussing procedure in the meeting. There is little possibility of impulse voting, because electronic voting might not influence the intent of active shareholders who want to attend the meeting and it might not induce the shareholders who were usually unconcerned with the meeting to vote. Second, a clause about the definition of executive officer needs to be added in the bill. The executive officer isn't a new or unseen one in the organization of corporation in Korea. Vice president, senior executive officer, executive officer and vice executive officer are similar name to executive officer of corporation law of America, However, even if the name of executive officer were same in each corporations, he or she has different authority compared to that of other corporation's officer. The clause about definition of officer is needed for the unity in using the names of officer. Third, corporate opportunity doctrine should be introduced as a independent clause not as a kind of director's self dealing transactions. The doctrine has been classified into one of the examples of violating director's duty of loyalty, not into the director's self dealing transactions. And the clause about corporate opportunity(section 398 ③) demands to approve the director's act in advance by board of directors and fairness of the act. The demand of approval and fairness is too rigid for corporation and directors, because the corporation would suffer no harm from the act of director if it were fair to the interest of corporation. The opposite views say that the reform proposal may cause enterprisers to slump and economy to be unstable. But if we supplement some problems of the clauses, those are requisite for the protection of interests of corporation and shareholders. Such legislation about corporate governance will give corporations a frame of sound development.

주권이 발행되지 않은 회사에서 양도담보된 주식의 이중양도와 주주권의 귀속 및 행사 - 대법원 2014. 4. 30. 선고 2013다99942 판결 -

김재범 한국경영법률학회 2017 經營法律 Vol.27 No.2

The plaintiff received the stocks(95% of the issued stocks) of defendant company through the contract of mortgage of transfer and became a joint chief executive of the defendant. Then the assigners transferred the stocks doubly and the plaintiff was dismissed from his position. The plaintiff claimed the invalidation of the resolution of shareholders’ meeting which decided the dismission. The major point of the decision is that the stock transferee through the contract of mortgage of transfer hold the qualification of shareholder, however he can’t exercise the shareholder’s right with respect to the company before registration. The qualification of shareholder here means that he can ask for a registration. Where the transferee didn’t register and the resolution was made without the participation of transferee, then the resolution has not a serious defect which make it null or void. In my opinion, unlike the conclusion of the decision, the transferee through the contract of mortgage of transfer can exercise the share- holder’s right without registration in some case. For example, where the transferee of mortgage of transfer share has the contractual right on management and voting right and stock certificate is not issued and there are a few shareholders, then the article 337 Commercial Act couldn’t be strictly interpret. In closely held company where transferee received the majority of issued shares and had the position of management, he could assert the effect of transfer of shares against the company, because the company well recognized the stock transfer and the contract of voting right of transferee. In the decision the plaintiff was elected the joint chief executive, but it was not revealed that he was granted the shareholder’s right from the contract. If there was the agreement about it, then he could assert the effect of exercise of shareholder’s right against the company even without a registration. Provided that plaintiff was a real shareholder and the company(defendant) acknowledged the fact, the company couldn’t be exempted from the obligation of notice of convocation for plaintiff. However it had not been revealed that plaintiff was a real shareholder authorized to exercise a voting right. Where there was no agreement about the voting right and defendant didn’t admit the exercise of voting right for plaintiff, he could not assert his shareholder’s status against defendant without a registration. 사안에서 원고가 피고회사 주식을 양도담보계약에 의하여 양수한 후 공동대표이사에 선임되었으나 양도인이 해당 주식을 다시 이중으로 양도하였고, 이후 원고는 피고회사로부터 주주총회의 소집통지를 받지 못한 채 대표이사직에서 해임되어 자신을 해임한 주주총회결의의 효력을 다투었다. 대상판결의 주요요지는 주식양도담보계약으로 주식을 취득한 자는 회사에 대한 관계에서 주주자격을 가지며, 명의개서를 마치지 않은 주주(원고)는 회사에 대하여 주주권을 행사할 수 없다는 것이다. 여기서 주주자격이란 회사에 대하여 명의개서를 청구할 수 있는 지위를 말하고, 명의개서 안된 주식양수인에게 주주총회의 소집통지를 하지 않고 성립한 결의에는 부존재 또는 무효에 이르는 중대한 하자가 없다고 본다. 대상판결의 결론과 달리 일정한 경우에는 양수인은 명의개서 없이 주주권을 행사할 수 있다고 본다. 예컨대 주권발행 전이고, 소수의 주주로 구성된 회사에서 과반수주식에 대하여 양도담보계약을 체결하면서 경영권 및 주주권의 행사가 인정되는 경우이다. 이러한 회사에서 주식양도의 대항요건에 관한 상법 제337조는 엄격하게 해석될 수 없다. 폐쇄적인 회사에서 경영권이 부착된 과반수 주식이 양도되어 양도담보권자가 주주총회에서 의결권을 행사하여 경영자로 선임되는 경우 회사는 주식양도 및 의결권 행사에 관한 양도담보계약이 있음을 인지하고 그를 주주로 인정한 것이므로 그는 주주권의 행사를 회사에 대항할 수 있다고 본다. 사안에서 95%의 주식을 양도담보로 취득한 원고는 공동대표이사로 선임되었지만, 양도담보계약에 원고에게 피고회사의 주주권을 부여한 사항이 있었는지 여부는 밝혀지지 않았다. 만일 그에 관한 약정이 있었다면 원고는 피고회사에 대하여 주주권의 행사를 대항할 수 있다고 본다. 회사가 주주명부상의 주주들이 정당한 주주가 아님을 알고 있었을 뿐만 아니라 이를 쉽게 증명할 수 있는 경우 회사는 주주명부상의 주주에게 소집통지 한 행위로부터 면책되지 않는데, 원심과 달리 대법원은 이에 관한 판단을 하지 않았다. 대상판결에서 주주명부 면책력의 한계에 관한 판단이 필요하고 이를 위하여 원고가 진정한 주주라는 사실이 먼저 인정되어야 하지만, 주식양도담보계약에 담보주식의 의결권 행사에 관한 약정이 존재했는지가 불명확하므로 원고가 진정한 주주인지 여부에는 의문이 있다. 이에 관한 약정이 없었고 피고회사가 원고의 주주권 행사를 승인하지 않는 한 원고는 명의개서가 없이는 자신의 지위를 회사에 대항할 수 없다. 사안은 주식양도담보계약의 사실확정에 의하여 달리 판단될 수 있었으나 원고의 주장이 부족했던 것으로 보인다.

컴퓨터 시뮬레이션을 이용한 MHC의 유전적 다형현상에 관한 연구

김재범,서동상 成均館大學校 科學技術硏究所 1990 論文集 Vol.41 No.2

To investigate the polymorphism of the major histocompatibility complex (MHC) loci in rodents and primates, a computer simulation study under the overdominance model was conducted. In this simulation the effective population size(N_e) (100, 1000 and 10000), mutation rate of MHC (μ) (10^-5, 10^-6, 10^-7), and selection coefficient (s)(0.05, 0.01, 0.001) were used as variables. Eighteen combinations of N_e, μ, and s were examined in this study. The results of all combinations have shown the same polymorphism pattern of the natural population of rodents and primates. These results suggest that one of the most important factors for the maintenance of MHC polymorphism is overdominant selection.

$\gamma$-plane 사파이어 기판 위에 성장한 무분극 ${alpha}$-plane GaN 층의 전기적 비등방성 연구

김재범,김동호,황성민,김태근,Kim, Jae-Bum,Kim, Dong-Ho,Hwang, Sung-Min,Kim, Tae-Geun 대한전자공학회 2010 電子工學會論文誌-SD (Semiconductor and devices) Vol.47 No.8

본 논문에서는 무분극 GaN층에서 관찰되는 성장축의 방향성에 따른 전기적 비등방성에 대한 연구를 수행하였다. 본 연구를 위해 $\gamma$-plane 사파이어 기판 상에 유기화학기상증착법 (Metal-organic chemical vapor deposition)을 이용하여 600 nm 두께의 ${\alpha}$-plane n-type GaN층을 성장시킨 후, Ti/Al/Ni/Au (20 nm/ 150 nm/ 30 nm/ 100 nm) 오믹 전극을 증착하여 transfer length method (TLM)로 접촉저항을 측정하였다. 그 결과, ${\alpha}$-plane GaN층이 갖는 축의 방향성에 의한 접촉저항이 차이는 없는 것을 확인하였고, 면저항 측정 시에는 m-축 방향에 비해 c-축 방향에서 발생하는 면저항 값이 약 25%~75% 정도 크게 발생하는 것을 확인할 수 있었다. 이러한 전기적 특성의 비등방성은 c-축 성장방향에 대해 수직방향을 갖는 기저적층결함 (basal stacking faults)의 생성으로 인한 전자들의 거동 저하에 의한 것으로 사료된다. We report on the electrical properties of Ti/Al/Ni/Au (20 nm/ 150 nm/ 30 nm/ 100 nm) Ohmic contacts and the anisotropic conductivity of n-type ${\alpha}$-plane ([11-20]) GaN grown on $\gamma$-plane ([1-102]) sapphire substrates. The Ti/Al/Ni/Au Ohmic contacts and their sheet resistances are characterized by using the transfer length method (TLM) as a function of azimuthal angles. It is found that the specific contact resistance does not depend on the axis orientation and there are significant electrical anisotropy in ${\alpha}$-plane GaN films on $\gamma$-plane sapphire substrates, and the sheet resistance varies with azimuthal angles. The sheet resistance values in the direction parallel to m-axis [1-100] are 25% ~ 75% lower than those parallel to c-axis [0001] directions. Thus, Basal stacking faults (BSFs) are offered as a feasible source of the anisotropic mobility in defected m-axis direction because the band-edge discontinuities owing to the differential band gap structure.
