Nowadays the Korean peninsula is continuing the cessation of hostilities depending on a conclusion of "Agreement Concerning A Military in Korea, pannmunjon, july 27, 1953. From a principle of a truce of view, the cessation of hostilities is not a peace itself and it is very distinct that it doesn't mean the termination of the war. As a matter of fact, continuation of the cessation of hostilities between The Republic of Korea and The authority of North Korea depends materially on the power of military affairs rather than the establishment of institutions. And The Authority of North Korea recently set up and promulagated, authenticating in no provision of agreement concerning a military armistice, military warning area in the sea holding the significance of military affairs and economic zone being vested with the national sovereignty as well as the frequent use of armed forces in the sea. We can advocate that such a measurement intimidates subject matter which Five islands groups of Paengyong-Do, Taechong-Do, Yongpyong-Do and U-Do to the yellow sea are particulary under the military controls of the commander-in-chief, United Nations Command according to article 2 paragraph 13 of Agreement Concerning A Military Armistice in Korea. 1953 and implies disaffirmation of the facts that the authority of North Korea has observed provisions of the agreement above since 20 years after its contracting. Strictly speaking, it is very clear that the sea belt of these island mentioned is completely situated at a distance exceeding the width of the territorial sea to the side of the authority of North Korea. Every island, however exceedingly small an island may be, keeps the sea belt of the territorial sea by the examination of general reles of international law. The reason is on the grounds of the fact adopted in article 10 paragrph 2 of Convention on the Territorial Sea and the Contiguous Zone, 1958. Now that all the island hold its own territorial sea on the bases of general rules of international law and Geneva Convention, in plain terms Five islands group mentioned to the yellow sea hold its own territorial sea. The Authority of North Korea, accordingly, has the advocacies of no legal ground and is not endorse wholly. The illegality of the Authority of North Korea can be distinctly approved in the light of the Conventions and the principles of the international law.

The international life of the human being is going to consist of the international groups obedient to the authority with uniformity. But in situations that the international society is not unified like to day and the coeisting nations make the Norm requiring for the government by the municipal law, the Common norm Prepared by each the notion should be keeped mutually. In these senses, to teat the articles with the international interested relations in the relationships of each nations, if it is the international law to be prepared, what differences are there in it establishment, application & excoution···etc, between the internatonal & the municipal law? In point of view that the international and municipal laws objectify the same articles in rules, when collide & Conflict & Contradict with the same artices until the nations abolish the municipal laws in Contravention of the international laws, what public orders are the people under the Control of and are or aren't there the superiorities between the international and the municipal law? I am willing to observe about all of the above at these issues.

According to the exposure of the changed aspects as a result of long term severity of 'The Cold War' and the atomic energy competition, the international society keeps up 'The Ballance of the Fear' in this time. In this status, emphasizing the changes from the instruction of the utopianic political views about the league of nations by woodrow wilson for the past some years to the realistic political views of the united nations by Roosevelt will be guarantee the peace and security of international society easily, carefully. That is to say, both the League of nation and the United Nations produced as a result of the world war Ⅰ and Ⅱ are organized during this war, and that these organization are continuity of international quarters. Consequently, not only because of the triumphed nations intend to have intention of the everlasting victory, but also because of much more the differentiations among the purpose, the principle and doctrine which no vaday international state and world-wide organization stand for, it is more difficult to establish it's enforcement and security. As the methods of maintaining the peace and security of international society, I wish to make comparative study the following results in terms of the aspects in realistic powerful politics and the principle in Ballance of force; First, the problems related to the self-defense. Second, The problems related to the covenants of the League of nations and the collective security, Third, the charter of the United Nations and the collective security problems (especially, problems related to the General Assembly, the security council, the regional agreement and the rights of the collective self-defense etc) If the united nations will procedure completely the native purposes to sustain the place and the security of international society, it'll be essential to find not only the only way preventing tyranny of super powers and privileged consciousness, but the only one using the atomic energy or nuclear weapons, which the dominant super ones have, for the world peace and it's order of security.

선형판별분석에서의 변수 선택

하재환,박창이 한국자료분석학회 2009 Journal of the Korean Data Analysis Society Vol.11 No.1

Along with logistic regression, linear discriminant analysis is a commonly used classification technique in practice. However, for high dimensional data, linear discriminant analysis has some drawbacks. Since linear discriminant analysis does not have the capability of variable selection, its final model may be difficult to interpret and its prediction error may increase due to noise variables in the final model. According to Bishop (1995), linear discriminant analysis and the regression with appropriately transformed output variable yield the same solution. In this paper, we study variable selection problem via a penalized regression with LASSO penalty. While best subset selection methods in regression does a discrete subset selection, LASSO regression does a continuous selection. In particular, the method yields sparse solution when true underlying discriminant function is sparse. So the method is expected to be efficient for high dimensional data with a few relevant variables. Through simulated and real data analysis, we illustrate that the method can select relevant variables effectively and may outperform linear discriminant analysis and best subset selection in presence of noise variables. 선형판별분석은 로지스틱회귀와 함께 현실의 문제에 자주 사용되는 분류기법이다. 그러나 고차원 자료에 대하여 선형판별분석은 몇 가지 단점이 있다. 선형판별분석은 변수 선택 기능이 없기 때문에 그 최종모형의 해석력이 떨어질 수 있고 잡음변수가 많아지면 예측력 또한 떨어질 수 있다. Bishop(1995)에 따르면 이항분류(binary classification)문제에서 선형판별분석과 출력변수를 적절히 새로 코딩한 회귀분석의 해가 동일하다. 본 논문에서는 이러한 결과를 이용하여 라쏘(least absolute shrinkage and selection operator, LASSO) 회귀를 통한 변수선택을 연구한다. 기존 회귀분석의 최적 부분집합 선택법(best subset selection)은 불연속적으로 부분집합의 선택이 이루어지는 반면 LASSO 회귀는 연속적으로 선택을 한다. 특히 본 논문의 방법은 실제 판별함수가 성근(sparse) 경우에 성근 해를 준다. 따라서 이 방법은 변별력 있는 변수의 개수가 작은 고차원 자료에서 효과적일 것으로 기대된다. 모의실험 및 실제 자료 분석을 통하여 이 방법이 잡음 변수가 많은 경우에 설명력 있는 변수들을 효과적으로 잘 선택하고 선형판별분석과 최적 부분집합 선택법에 비해 더 효율적임을 보였다.

2P-211 Synthesis of High Quality MoSe₂ Monolayer by Chemical Vapor Deposition

하재환,오준학 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1

In recent years, two-dimensional materials such as graphene and transition metal dichalcogenides(TMDCs) have attracted great attention due to their excellent electronic and optical properties. These 2D materials have potential for use in nanoelectronics, photonics, sensor, and optoelectronics. Among the various methods to synthesis, large area and high quality monolayer 2D materials can be obtained by the chemical vapor deposition (CVD) method. In CVD process, the most important factor is the nucleation of crystals. To promote the formation of large size single crystal domains, complicated growth techniques or surface treatment methods are critical for controlling nucleation processes. In this research, we have synthesized a high quality MoSe₂ monolayer focusing on changing the factors of CVD process such as H₂ flow rate and process temperature. These results demonstrate the impact of various parameters that affect crystal nucleation density during the synthesis process of MoSe₂.

人權의 國際法的 意義

The thought on Human Rights has an eternal history, and since it is the foundation in maintaining human dignity the value of moral judgment is, we may say, absolnte. Modern international law does not ignore the private right, and this tendency is becoming more prevailed since the world war Ⅱ which eventually lead to the adoption of Declaration of its intention (Universal Declaration of Human Rights) by the General Assembly of the United Nations. However, it is very worth while to notice that the establishment of the International Labor organization based upon International Labor Regulation has been, in the light of esteem, protection and promotion, provoked and protected the fundamental social right and or the right of labor since the time of the league of nations, especially the protectoral Agreement on Minority Races, which is the general rights for the Human value, has promoted the protection of human Rights, and its influence upon various fields of international social activities by modern nations is very great. Then, arise of esteem and protection of Human Rights and Freedom, as a principle of international organization can be said the result of sound and steadfast efforts of Human being, and the principle on law of nations "Intervention on the grounds humanity" of present days, is, we may say, a symbol expressing the world intention thereof party. Therefore, though the world is devided into two blocs on the account of inconsistency of ideas, by the Declaration of these Human Rights and freedom as a new common principle in the international society, they seemed as if they were united, but the subjects of protection, esteem , and promotion of Human Rights are still containing in themselves much problems together with the law of nations.
