  • 원자력 발전소에서 비상사태가 발생하는 경우를 대비하여 비상 발전기의 고장진단시스템을 구축할 필요가 있다. 고장진단시스템의 지식베이스를 구현하기 위해서는 클래스와 인과관계 모형을 설계해야 한다. 클래스와 인과관계 모형을 설계하기 위해 먼저 진단대상을 선정하고, 정상과 비정상의 상태정보를 조사하여 시스템의 작동 원리를 외부지식인 개체와 활동으로 추출한다. 추출된 외부지식을 내부지식으로 표현하기 위해 개체를 클래스로 정의하고 활동을 인과관계로 변환한다. 인과관계의 반복적인 설정과 타당성 검토를 통해 지식베이스에 이식할 수 있는 수준의 진단지식을 완성한다. 본 연구는 결정테이블을 통한 설계 모형의 독립성을 고려하였기 때문에 이식성 높은 지식베이스의 구현이 가능하다.

  • Records from a total of 202 crossbred pigs were classified by their ear type and coat color to examine the presence of interrelationships with growth performances. Crossbred pigs were F2 generations of full sib family out of ten Landrace sows bred by 5 Korean domestic boars. Heavily drooped ear type was predominant, 195 out of 202 pigs over the other two types (1 straight and 6 slightly drooped). Coat colors were classified as four categories, all white, all black, dominant white or dominant black. Ratio among coat color categories did not fall within Mendelian principle of independence regarding two loci involved. There was dependency between ear type and coat color. However, due to rarity of ear types other than heavy drooped, dependency comes from distribution of those rare ear types. Three least squares models to test the effect of ear type and coat colors on growth performances were analyzed. First model analyzed effects on birth weight, body weight at 3 and 6 weeks and ADG' before weaning and between 3 and 5 weeks of age. This model included sex in addition to ear type and coat color. Second model analyzed postweaning growth traits (initial weight, final weight and ADG between these periods) upon initiation of performance testing. This model included effects of sex, test group and start age (as a covariate) in addition. Third model was fit for fasted weight before slaughter and included the effects of sex, test group and age at slaughter (as a covariate). The effects of sex and ear type were not significant source of variation for all traits. Test group was a significant source of variation for all the postweaning traits. Effect of coat color was not significant until the initiation of performance testing and became significant then after. Least squares means of dominantly black pigs were significantly lower than the other three coat colored pigs in final weight around 195 days of age and in ADG from the start of performance test and final weight measure.

  • While a performance type guarantee is required as a security for non-performance risk by a seller, a payment guarantee is used as a security for non-payment risk by a buyer(or a borrower in a loan agreement). A payment guarantee is a type of independent bank guarantee, bank guarantee, bond, demand guarantee, or standby letter of credit. A guarantor accepts a credit risk of a principal which is normally a buyer in a contract for sale of goods. A payment guarantee is independent of the underlying relationship between the applicant and the beneficiary. The guarantor is only empowered to examine the beneficiary's demand and determine the payment on its face to the terms of the guarantee. A payment guarantee is thus different from a suretyship. The principle of independence carries a significant advantages for a guarantor as well as for a beneficiary. While a documentary credit requires B/L, commercial invoice, packing list, inspection certificate, etc., a typical payment guarantee does not require any evidence for a seller's performance of the underlying contract other than written demand. In this respect payment guarnatee can be a more secured facility than a documentary credit. A payment guarantee normally comes into force from the issuing date and shall remain in effect until all sums guaranteed shall be paid in full by a buyer(or a borrower) or by a guarantor. Although a guarantor shall pay a demand made in accordance with the terms and conditions of the payment guarantee, a payment demand may be denied when it is determined to be abusive or unfair.

  • 국민의 기본권 보호는 국가의 당연한 의무이다. 헌법은 국가의 기본권 보호 의무를 명시적으로 선언하고 있으며 이에 입각하여 국가는 국민의 기본권 보장을 위하여 보다 적극적인 수준에서 의무를 부담한다고 보아야 한다. 물론 근대시민국가에서는 자유권 보장에 주안점을 두었고 현대국가에서는 사회권 혹은 생존권 보장에 더 많은 관심을 둔 것이 사실이지만 국가의 자유권 보장을 위한 의무를 강조하지 않을 수는 없다. 그렇다면 여전히 국민의 기본권 보장을 위한 노력을 경주하여야 하는 것이고 이에 따라 입법자는 보다 구체적인 행위의무를 부담한다고 볼 수 있게 된다. 특히 승강기는 우리 생활에 필수적이라는 점에서 그리고 이의 피해는 상당히 치명적이라는 점에서 이의 안전성 확보를 위한 방안은 매우 중요하고 국가의 행위의무 역시 상당히 중요하다고 볼 수밖에 없다. 특히 민간 수준의 행위자의 역할을 강조하는 영국의 경험은 우리에게도 상당 정도의 시사점을 던져 주고 있는 것이 사실이어서 안전성 제고를 위한 설치 전 안전성 점검, 부품 품질관리, 검사기준의 구체화, 검사주기의 다각화 등의 물적 사항과 점검자 자격 구체화, 점검자 독립성 보장, 승강기 책무자 다양화 및 이용자책무의 다각화 등의 인적 사항들은 우리에게도 충분히 고려할 만한 사항이다. 하지만 영국의 상황과 우리의 상황이 정확히 일치하는 것은 아니라는 점에서 그들의 정책을 금과옥조로 삼을 수만은 없다. 즉 영국의 정책을 절대적으로 수용할 필요는 없는 것이며 다만 정책의 특징을 고려하여 타당한 정책이라면 우리의 법제에 적절하게 적용하는 운영의 묘를 발휘하여야 하는 것이다.

  • 공동체 아카이브는 공동체가 생산하거나 수집한 기록이며, 축적된 기록은 공동체의 역사를 기억할 수 있도록 해주는 자원이 된다. 이러한 기록 중 어떠한 기록을 남길지는 평가를 통해 결정되며, 이는 결과적으로 그 사회가 어떤 기억을 남길지를 정하는 정치적인 행위의 성격을 지니게 된다. 동일한 역사적 경험을 하였다고 해도 관점이나 입장에 따라 이에 대한 기억은 달라질 수 있기 때문에 공동체는 자신들의 기록이 자신들의 관점에서 남겨지기를 원한다. 이 연구는 기존의 기록평가론이 공동체 아카이브의 평가에 있어서 갖는 의미와 한계는 무엇인지 분석하고 공동체 아카이브를 위한 평가 방향을 제안하기 위한 것이다. 우선 공동체가 자신들의 기록의 수집하고 보존하는 목적은 무엇인지, 공동체가 아카이브가 공동체는 물론 사회적으로는 어떤 의미를 가지는지를 제시하기 위하여 정체성, 기억투쟁, 가치의 개별성, 기억과정을 중심으로 분석하였다. 공동체와 사회에서 공동체 아카이브의 의미 설정은 기록평가의 방향에 큰 영향을 미치기 때문이다. 다음에는 기록평가론의 흐름을 패러다임별로 살펴보았다. 기존의 기록평가론이 대부분 정부기록, 공식조직의 기록에 초점을 맞추고 있기 때문에 이러한 접근법이 비공식조직 및 개인이 주로 생산하는 공동체 아카이브에도 적용될 수 있는지 숙고할 필요가 있다. 특히 공동체 아카이브 평가론이 어떻게 전개되어야 하는지, 평가론의 흐름상 어떤 지점에 위치하게 될지를 생각해본다는 측면에서 분석하였다. 이중 사회적 접근법을 응용하되 공동체 아카이브를 위한 새로운 평가모형을 평가의 목적과 대상, 원칙과 기준, 주체와 협력을 중심으로 제시하였다. 평가의 목적을 평가가 이루어질 수 있는 두 개의 국면으로 나누어 제시하고, 다양성을 중심으로 원칙을 제시하였으며, 평가 주체와 관련하여 공동체와 주류 문화기관의 협력 모형을 제안하였다. 이는 '로컬리티 기록화'를 통해 축적된 다양한 소규모의 '공동체에 관한 아카이브'들을 '공동체 아카이브' 로 전환하는 과정에서 기록관리 전문가집단과 공동체 구성원들이 어떻게 협력해야 할지를 모색하는 데에도 활용될 수 있을 것이다.

  • The character of the educational tradition of Germany could be divided into two aspects. One is the humanistic liberal tendency and the other is vocational. From the beginning of the Twentieth Century, however, there has been an attempt to unify these two trends by the . Georg Kerschensteiner is the first of importance to make some comprehensive curriculum for this goal. In Kerschensteiner, the genuine education makes the individual assume his work and role in society, and to develop them by cultivating insight, will and power. His view is well expressed in the slogn "The vocational education is the beginning of the humanistic education." His goal is to make men of independence and autonomy through vocational education. The theory of Kerschensteiner's education is called 'general vocational education'. The reason why is that his vocational education concerns not just technical training for industry, but also general liberal arts. In this point, Kerschensteiner's point of view goes back to Wilhelm von Humboldt, neo-humanist afar in the first half of the Ninteenth Century, and to John Dewey, pragmatist in the contemporary age of Kerschensteiner. Kerschensteiner was much influenced by Humboldt's concepts of power and individuality. These concepts came to be embodied as a principle of vocational education in Kerschensteiner. Furthermore, Humboldt's concept of power could be associated with Dewey's theory of reflexive thinking. The power in Humboldt is to create spirit, which is connected with the world outside through language. The reflexive thinking of Dewey is a process that examines and selects some alternative thinking in the consciousness before acting. This process makes one find the method of problem-solving which results in behaviour. That is the experimental spirit or pragmatic behaviourism. These theories are reduced to the concept of 'work' in Kerschensteiner. And Kerschensteiner's theory of education that has both sides, humanistic and vocational, is similar to that of John Dewey. Dewey brings forward the idea that the vocational education is the best way to cultivate intelligence and emotion, as intelligence operates best in the life. The position of Dewey is in accord with that of Kerschensteiner who intends to cover experiences of various fields of society through practice-learning, and to have knowledge got from outside of school, refuting the misled trend of education isolated from real life. However, there is some difference between Kerschensteiner and Humbolt or Dewey. While the Neo-humanism of Humbolt and the pragmatic education of Dewey put emphasis rather on the liberal arts and culture of individuality, Kerschensteiner is concerned more with the work and life of the reality of society as a group. Kerschensteiner's concept of utility is related to education for the whole man and to the work of the individual and the nation as well as the will and power to practice it. The ideal man of utility of Kerschensteiner is to learn perfectly the value and behaviour of society through vocational life and to have right view of the state establishing a sound mutual relation between individual and state. Kerschensteiner is regarded as a devotee of 'the state of harmony' or 'the ideal of the state', as he makes the state as the criterion for defining the role of the individual. It can be said that Kerschensteiner is not a democrat of the American style as Dewey is, as he makes much of the value of the nation and state. However, he is a humanist and democrat in the point of vocational education. His purpose of education is to make whole men through work and vocational education.

정전협정 60년, NLL과 서북 도서 (60 Years since the Armistice Treaty, the NLL and the North-Western Islands)

  • The United Nations Command (UNC) and the communist North failed to reach an agreement on where the maritime demarcation line should be drawn in the process of signing a truce after the Korean War because of the starkly different positions on the boundary of their territorial waters. As a result, the Armistice Treaty was signed on July 1953 without clarification about the maritime border. In the following month, Commander of the UNC unilaterally declared the Northern Limit Line (NLL) as a complementing measure to the Armistice. Referring to this, North Korea and its followers in South Korea wrongfully argue that the NLL is a "ghost line" that was established not based on the international law. However, one should note that the waters south of the NLL has always been under South Korea's jurisdiction since Korea's independence from Japan on August 15, 1945. There is no need to ask North Korea's approval for declaring the territorial waters that had already been under our sovereign jurisdiction. We do not need North Korea's approval just as we do not need Japan's approval with regard to our sovereign right over Dokdo. The legal status of the NLL may be explained with the following three characteristics. First, the NLL is a de facto maritime borderline that defines the territorial waters under the respective jurisdiction of the two divided countries. Second, the NLL in the West Sea also serves as a de facto military demarcation line at sea that can be likened to the border on the ground. Third, as a contacting line where the sea areas controlled by the two Koreas meet, the NLL is a maritime non-aggression line that was established on the legal basis of the 'acquiescence' element stipulated by the Inter-Korea Basic Agreement (article 11) and the Supplement on the Non-aggression principle (article 10). Particularly from the perspective of the domestic law, the NLL should be understood as a boundary defining areas controlled by temporarily divided states (not two different states) because the problem exists between a legitimate central government (South Korea) and an anti-government group (North Korea). In this sense, the NLL problem should be viewed not in terms of territorial preservation or expansion. Rather, it should be understood as a matter of national identity related to territorial sovereignty and national pride. North Korea's continuous efforts to problematize the NLL may be part of its strategy to nullify the Armistice Treaty. In other words, North Korea tries to take away the basis of the NLL by abrogating the Armistice Treaty and creating a condition in which the United Nations Command can be dissolved. By doing so, North Korea may be able to start the process for the peace treaty with the United States and reestablish a maritime line of its interest. So, North Korea's rationale behind making the NLL a disputed line is to deny the effectiveness of the NLL and ask for the establishment of a new legal boundary. Such an effort should be understood as part of a strategy to make the NLL question a political and military dispute (the similar motivation can be found in Japan's effort to make Dokdo a disputed Island). Therefore, the South Korean government should not accommodate such hidden intentions and strategy of North Korea. The NLL has been the de facto maritime border (that defines our territorial waters) and military demarcation line at sea that we have defended with a lot of sacrifice for the last sixty years. This is the line that our government and the military must defend in the future as we have done so far. Our commitment to the defense of the NLL is not only a matter of national policy protecting territorial sovereignty and jurisdiction; it is also our responsibility for those who were fallen while defending the North-Western Islands and the NLL.

독립적 보증과 그 부당한 청구에 대한 대응방안 연구 (A Study on How to Cope with the Abusive Call on On-demand Bonds)

  • Recently the abusive calls on on-demand bonds have been a critical issue among many engineering and construction companies in Korea. On-demand bond is referred to as an independent guarantee in the sense that the guarantee is independent from its underlying contract although it was issued based on such underlying contract. For this reason, the issuing bank is not required to and/or entitled to look into whether there really is a breach of underlying contract in relation to the call on demand-bonds. Due to this kind of principle of independence, the applicant has to run the risk of the on demand bond being called by the beneficiary without due grounds. Only where the call proves to be fraudulent or abusive in a very clear way, the issuing bank would not be obligated to pay the bond proceeds for the call on on-demand bonds. In order to prevent the issuing bank from paying the proceeds under the on-demand bond, the applicant usually files with its competent court an application for injunction prohibiting the beneficiary from calling against the issuing bank. However, it is in practice difficult for the applicant to prove the beneficiary's call on the bond to be fraudulent since the courts in almost all the jurisdictions of advanced countries require very strict and objective evidences such as the documents which were signed by the owner (beneficiary) or any other third party like the engineer. There is another way of preventing the beneficiary from calling on the bond, which is often utilized especially in the United Kingdom or Western European countries such as Germany. Based upon the underlying contract, the contractor which is at the same time the applicant of on-demand bond requests the court to order the owner (the beneficiary) not to call on the bond. In this case, there apparently seems to be no reason why the court should apply the strict fraud rule to determine whether to grant an injunction in that the underlying legal relationship was created based on a construction contract rather than a bond. However, in most jurisdictions except for United Kingdom and Singapore, the court also applies the strict fraud rule on the ground that the parties promised to make the on-demand bond issued under the construction contract. This kind of injunction is highly unlikely to be utilized on the international level because it is very difficult in normal situations to establish the international jurisdiction towards the beneficiary which will be usually located outside the jurisdiction of the relevant court. This kind of injunction ordering the owner not to call on the bond can be rendered by the arbitrator as well even though the arbitrator has no coercive power for the owner to follow it. Normally there would be no arbitral tribunal existing at the time of the bond being called. In this case, the emergency arbitrator which most of the international arbitration rules such as ICC, LCIA and SIAC, etc. adopt can be utilized. Finally, the contractor can block the issuing bank from paying the bond proceeds by way of a provisional attachment in case where it also has rights to claim some unpaid interim payments or damages. This is the preservative measure under civil law system, which the lawyers from common law system are not familiar with. As explained in this article, it is very difficult to block the issuing bank from paying in response to the bond call by the beneficiary even if the call has no valid ground under the underlying construction contract. Therefore, it is necessary for the applicants who are normally engineering and construction companies to be prudent to make on-demand bonds issued. They need to take into account the creditability of the project owner as well as trustworthiness of the judiciary system of the country where the owner is domiciled.

국민연금기금의 복지사업 당위성과 정책방향 연구 (The Welfare Investment of the National Pension Funds: Its Necessity and Policy Development)

  • 국민연금기금의 복지사업운용은 낮은 수익률이 비판의 대상이 되고 있으며, 매우 낮은 규모에도 불구하고 지속적으로 감소 추세에 있다. 더구나 최근에는 국민연금기금의 복지투자를 포기하고자 하는 주장이 제기되고 있다. 이러한 경향은 국민연금기금의 복지투자에 대하여 논리적 타당성을 확립하지 못한 점과 정책방향의 정립이 미흡한 데에 따른 결과라 할 수 있다. 공적연금으로서 국민연금의 기금운용의 하나로 복지사업에 대한 투자는 세 가지 점에서 논리적 근거를 갖는다. 국가가 복지사업을 모두 책임 질 수 없다는 점에서 기금의 복지투자는 기금운용의 대상에서 제외되지 않는다는 충분조건이 아닌 필요조건으로 근거로 제시될 수 있다. 국민연금의 적립방식은 최근 대부분의 국가들이 공적연금에서 부과방식을 선택하는 경향과는 차별이 된다. 특히 노후보장과 관련하여 현재 노인계층을 연금보장 대상에서 제도적으로 배제시켜는 점은 선진국과는 다른 차별로 볼 수 있다. 마지막으로 재정방식에서 선별주의방식을 채택함으로써 국민연금 연금수급권을 위한 최소 가입기간(10년)은 한계가입자와 일반계층과의 형평성 문제를 해결하여야 한다는 논리성의 한계를 제시할 수 있다. 따라서 기금의 복지사업은 가입자나 수급권자 보다는 현재 노인계층과 한계가입자계층에 대한 차별성을 완화하는 목적에서 사업대상으로 고려될 수 있다. 한편 복지사업의 정책결정은 수익성에 있어서 사회적 합의의 필요성, 국가사업과의 관계를 고려한 정책 사업의 독립성 그리고 투자의 장단기적 성격을 판단하기 위한 정책성격의 확립 그리고 복지사업의 직 간접경영에 따른 신뢰성 등 다양한 정책요소를 고려한 정책방향이 이루어져야 한다. 이를 통하여 국민연금기금 운용의 복지사업 활성화와 신뢰확보를 기대할 수 있을 것이다.
