Let {X, $X_{n}, n\;{\geq}\;1$} be a sequence of identically distributed, negatively associated (NA) random variables and assume that $│X│^{r}$, r > 0, has a finite moment generating function. A strong law of large numbers is established for weighted sums of these variables.

This paper attempts to assess the Basel Committee's bank supervisory standards and capital adequacy rules, and thereby rethink whether global convergence in banking regulation is desirable. To that end, it seeks to address the impetus for the creation of the Basel Committee, and explore driving forces behind the internationalization of bank regulatory and supervisory standards. Following the historical and theoretical analysis of the internationalization of bank regulatory standards, the movement toward global standards in banking is reviewed. More importantly, this paper seeks to explore the origins of the Basel Accord on bank capital adequacy. To do so, it largely relies on current theories on the process of negotiating the capital adequacy standards in the areas of political science and international political economy. At this point, this study takes a position as a break against the force of international market failure logic that has enjoyed an exceptionally positive reception among economists, political scientists, and legal experts. Nonetheless, it does not intend to freeze the international coordination and cooperation of banking regulation. Given the understanding of the politics behind the creation of the Basel Accord, this paper evaluates the Basel Accord of 1988 and the new capital adequacy framework(Basel II), and then moves beyond the assessment of the capital adequacy standards In doing so, this study draws lessons from Basel in search of a just world order in the global finance.

The objective of this paper is to present abacuses obtained from a parametric study of deep-lined tunnels using a numerical finite element model. This numerical model was implemented in software GEOMEC91, which is a two-dimensional axisymmetric model that considers the progress of excavation and the placing of the lining through the activation and deactivation of elements. It is adopted a step of excavation constant (1/3 of radius), constant velocity and circular cross section along the tunnel axis. It is used for rock mass a viscoplastic constitutive law with von-Mises criterion of viscoplasticity without hardening whose deformation rate over time is given by the Bingham model. The lining uses a linear elastic constitutive law. In total are 1716 analysis presented in 60 abacuses that show the value of ultimate convergence ($U_{eq}$) due to tunneling speed. In addition, it is shown an example of the use of the abacuses to determine the ultimate convergence ($U_{eq}$) of the tunnel and pressure ($P_{eq}$) on the lining.

Korea's laws regarding ICT must follow the Void for vagueness doctrine, the Principle of forbidden general delegation, the Principle of justification of system and the Principle of balancing test in the Constitution. The Act for the Promotion and Convergence and so on of Information and Communication in the Future should be improved as follows. It is desirable to improve the part where the principle of system justification of the Constitution is problematic in relation to existing laws. It is desirable to improve the ICT's policies on industry and convergence technologies so that they are well balanced between promotion and regulation of ICT's industries. It is desirable to improve the information service policy and legislative makeup relationship between various government agencies related to ICT. It is therefore desirable to improve the institutional complement to the post-regulatory framework for the protection of users of ICT in the future. It is desirable to create a device to replace the functions of the Information Service Budget Council in the special law of ICT.

Feller introduced an unfair-fair-game in his famous book [3]. In this game, at each trial, player will win 2^k yuan with probability p_k = 1/2^kk(k + 1), k ∈ ℕ, and zero yuan with probability p₀ = 1 - Σ^∞_k=1 p_k. Because the expected gain is 1, player must pay one yuan as the entrance fee for each trial. Although this game seemed "fair", Feller [2] proved that when the total trial number n is large enough, player will loss n yuan with its probability approximate 1. So it's an "unfair" game. In this paper, we study in depth its convergence in probability, almost sure convergence and convergence in distribution. Furthermore, we try to take 2^k = m to reduce the values of random variables and their corresponding probabilities at the same time, thus a new probability model is introduced, which is called as the related model of Feller's unfair-fair-game. We find out that this new model follows a long-tailed distribution. We obtain its weak law of large numbers, strong law of large numbers and central limit theorem. These results show that their probability limit behaviours of these two models are quite different.

일본은 2006년 탐정업자 및 흥신소의 불법적인 영업과 난립을 막기 위하여 탐정업무의 적정화에 관한 법률을 제정 및 시행하게 되었다. 법률 제정이후 2012년 현재 일본의 탐정업과 관련하여 여전히 문제점들이 발생하고 있어, 일본의 관할 기관들은 이러한 문제점들을 개선하기 위해 해당 법령 개정 및 업자들에 대한 의식개선에 노력을 기울이고 있다. 따라서 향후 우리나라가 민간조사업 도입에 있어 시사 하는바가 크다고 할 수 있는데 이들 내용을 정리해 보면 다음과 같다. 첫째, 탐정업무 수행에 따른 타법령과의 문제점 개선이다. 둘째, 탐정업 위반업자의 관리 강화이다. 셋째, 탐정 업무수탁에 따른 비용의 적정화 추진이다. 민간조사업이라는 해당 업무가 보다 사회에 공익적 기능을 할 수 있도록 일본의 이러한 문제점들을 더욱더 보안하고 개선방안을 마련하여 민간조사 산업의 발전과 사회적 순기능의 관점에서 제19대에 국회에서는 반드시 입법발의 할 필요가 있다.

이 논문은 그동안 민간조사제도 도입에 관하여 논의되어 왔던 쟁점들에 대한 연구동향을 분석하여 그 시사점을 돌출함으로써, 바람직한 도입 방향을 제시하는데 연구목적을 두고자 한다. 분석한 쟁점들은 민간조사제도 도입에 관한 기존의 연구물들을 대상으로 추출하였다. 연구자들이 지적한 쟁점사항들은 명칭, 업무범위, 법인, 자격제도(자격기준 및 시험), 교육, 협회설립, 감독기관, 입법형태 등 8개의 범주안에 포함된다. 명칭에 대해서는 '탐정'이라는 명칭으로 통일할 필요가 있다고 본다. 업무범위에 대해서는 개정이 어려운 법률에서는 일반적인 업무규정을 개괄적으로 두고, 보다 구체적이고 세부적인 조사업무내용은 시행령을 통하여 규율하는 것이 합리적이라 할 수 있다. 민간조사제도는 법인으로의 제한적 운영이 필요하다고 본다. 교육에 대해서는 민간조사 종사자에 대한 신임교육과 재교육이 정기적으로 이루어져야 한다. 관리감독기관에 대해서 경찰청으로 일원화하여야 한다. 입법형태는 독자적인 법률로 규정하는 것보다는 경비업법의 개정을 통해 민간조사제도에 대하여 보완 규정하는 것이 효과적일 수 있다는 것이다.

최근 4차 산업혁명이 화두로 등장하면서 자율주행자동차에 대한 관심과 함께 상용화를 위한 연구개발이 활발히 이루어지면서 자율주행자동차의 중요성과 관심이 높아지고 있으며, 미국, 영국, 독일을 포함한 여러 국가들은 이러한 추세를 반영하여 자율주행자동차의 상용화에 따른 법제들을 마련하거나 기존 법률을 개정하고 있는 상황이다. 국내의 경우도 자율주행자동차의 상용화를 위한 임시운행과 연구개발이 이루어지고 있으나 자율주행자동차 상용화에 따른 법제들은 미비한 상황이다. 본고에서는 자율주행자동차 법률 체계에 기반 하여 미국, 영국, 독일의 법제 현황과 국내 법제 현황을 비교하여 자율주행자동차 상용화를 위한 법제와 정책과제를 제시하여 자율주행자동차 법률 체계 완성을 위한 단계별 추진방향을 제시한다. 또한 자율주행자동차 상용화에 따른 산업 발전을 위한 법제 정비 방향에 대한 방안을 제시한다.

Convergence measurements play very important role in the assessment of stability of a tunnel and of the economics of rock reinforcements. The characteristics of convergences are both due to the face advance effect and the time-dependent behaviour of rocks. As the convergence law can be modeled as a specific function of two variables of distance and time, we can determine the type of function and the related parameters from the field measurements. By using the regression method based on the Levengberg-Marquardt algorithm, an analysis of convergence of two different tunnels and one numerical example is described. It is shown that the convergence can be modeled as following function, C(x)=a{1-exp(-bx)} or C(t)=a{1-exp(-bt)} in case of a tunnel excavated in elastic rocks, in case of elasto-plastic or over stressed rocks.

This paper investigates the convergence condition of ADILC(iterative learning control with advanced output data) for nonminimum phase systems. ADILC has simple learning structure including both minimum phase and nonminimum phase systems. However, for nonminimum phase systems, the overall time horizon must be considered in input update law. This makes the dimension of convergence condition matrix large. In this paper, a new sufficient condition is proposed to satisfy the convergence condition. Also, it has been shown that this sufficient condition can be satisfied although it is not full impulse response.
