더미 역설에 대한 양진주의적 해결전략이란 경계사례를 참인 모순으로 이해하는 것이다. 그러나 이러한 전략을 수용하기 위해서는 모순을 인정하지 않는 대안의 가능성을 먼저 고려해야 한다. 대안이 있다면 굳이 모순을 인정할 필요는 없기 때문이다. 이와 관련해서, 벨은 모순을 인정하지 않으면서 양진주의가 갖는 장점을 모두 갖는 대안을 제시한다. 필자는 이 글에서 이러한 벨의 주장이 성립하지 않음을 보일 것이다. 필자의 논의는 주로 울타리 도식(inclosure schema)에 기초한다. 필자는 더미 역설이 울타리 도식을 만족함을 보인 후, 이 도식에 기초해서 절단점의 존재를 거부하는 대안들이 모두 모순을 함축한다는 것을 보일 것이다. 물론, 이러한 대안에는 벨의 대안 역시 포함된다. 그리고 이것은 모호성에 대한 직관 즉, '관용'을 수용하는 한, 양진주의를 받아들여야 한다는 것을 의미한다.

An emergency response system (ERS) for vessel oil spills is a complex and dynamic system comprising a number of subsystems and activities. Failures may occur during the emergency response operations, this has negative impacts on the effectiveness of the ERS. Of the classes of problems in analyzing failures, the lack of quantitative data is fundamental. In fact, most of the empirical data collected via questionnaire survey is subjective in nature and is inevitably associated with uncertainties caused by the human being's inability to provide complete judgement. In addition, incomplete information and/or vagueness of the meaning about the failures add difficulties in evaluating the effectiveness of the system. Therefore this paper proposes a framework to evaluate the ERS effectiveness by using the combination of fuzzy reasoning and evidential synthesis approaches. Based on analyzing the procedure of ERS for oil spills, the failures in the system could be identified, using Analytic Hierarchy Process(AHP)to determine the relative weight of identified failures. Fuzzy reasoning combined with evidential synthesis is applied to evaluate the effectiveness of ERS for oil spills under uncertainties last. The proposed method is capable of dealing with uncertainties in data including ignorance and vagueness which traditional methods cannot effectively handle. A case study is used to illustrate the application of the proposed method.

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.

랜드스케이프 어바니즘이 이룬 성과만큼 담론에 대한 다양한 비판도 함께 제기되어왔다. 오늘날 랜드스케이프 어바니즘의 이론적 구도와 한계를 명확히 파악하기 위해서는 그동안 제기된 비판적 견해에 대한 고찰이 필요하다. 본 연구는 각각의 관점에 따라 제기되어온 여러 비판적 견해를 분석할 수 있는 종합적인 해석의 틀이 필요하다는 판단 하에 논리학과 기호학에서 사용되는 내포와 외연의 개념을 도입하여 분석을 진행한다. 랜드스케이프 어바니즘의 전개과정을 비판적 견해를 중심으로 통시적으로 재구성한 뒤, 이를 바탕으로 30여 편의 비판적 견해가 담긴 문헌을 선정하여 분석한다. 비판적 견해의 성격에 따라 내재적 비판과 외재적 비판으로 구분하고 이중 내재적 비판에 해당되는 견해들만을 본 연구의 주제로 다룬다. 랜드스케이프 어바니즘에 대한 내재적 비판은 이론, 실천, 그리고 이론과 실천과의 관계로 구분할 수 있다. 이론적 내용에 대한 비판은 개념의 모호함과 개념의 모순을 지적하는 비판들로 나누어진다. 이중 개념의 모호함은 사전적 애매함과 내포적 모호함으로 인해 발생한다. 기존의 개념을 확장적으로 재해석하면서 발생한 개념의 모호함의 문제는 담론의 구조적인 한계를 드러낸다. 실천에 대한 비판의 경우 실천적 결과의 부재, 형태중심적 실천, 기존 조경과의 실천적 차별성의 세 가지 유형으로 구분된다. 이중 실천적 결과의 차별성 부재는 다수의 경계사례를 허용하는 외연적 모호함으로 인해 나타나는데, 경계사례들이 기존 조경의 외연이나 경계사례와 중복이 되면서 담론의 정체성이 모호해지는 결과를 초래한다. 이론과 실천의 관계에 대한 비판은 대부분 실천적 방법론에 대한 문제를 제기한다. 이에 대한 비판들은 실천적 방법의 오류와 실천적 방법의 부재를 지적하는 두 가지 유형으로 나뉜다. 이 중 실천적 방법의 부재는 그동안 랜드스케이프 어바니즘이 제시한 해답으로는 해결이 될 수 없는 이론의 구조적인 문제에 해당된다. 담론의 구조적인 문제들은 랜드스케이프 어바니즘의 약점이기도 하지만 이론적인 영역을 확장하고 잠재성을 인정받을 수 있었던 요인으로 작용하기도 한다. 향후 랜드스케이프 어바니즘의 방향을 파악하기 위해서는 내재적 비판뿐만 아니라 외재적 비판에 대한 고찰도 함께 이루어져야 한다.

This paper is to discuss essential business of hospital business. While the labor world and ILO made continuous recommendation for improvements towards the compulsory arbitration system along with the controversy over unconstitutionality of the system, the Constitutional Court ruled that the system is constitutional on December 23, 1996(90hunba19) and on May 15, 2003 (2001hunga31). Despite this decision from the Constitutional Court, there has been much controversy over whether the compulsory arbitration system infringes the rights of collective action against the principle of trade union & labor relations adjustment which allows Commissioner of the Labor Relations Commission to decide on submission of arbitration by virtue of his/her authority in case where industrial disputes take place in the essential public-service businesses. The revision on the above provision was closely examined from the year 2003 and an agreement was made on the abolition of the compulsory arbitration system and the introduction of essential business with a grand compromise among labor unions, employers and the government on September 11, 2006 followed by revision(Essential business system enacted on January 1, 2008) of the Trade Union & Labor Relations Adjustment Act on December 30 in the same year. Accordingly, in order to perform the essential business, parties to labor relations must have an agreement or obtain a decision by the Labor Relations Commission before taking industrial actions. This paper firstly examined the concept of essential public-service businesses and essential business, legal meaning of essential business, procedures for making agreement and decision and legal effects. Secondly it intensively explored a theory against the principle of the legality which was raised from some part of society. In other words, it is claimed that a theory against the principle of the legality is not consistent with the rule of legislation and some abstract wording is against void for vagueness doctrine because part of crime constitution requirements is delegated to the Presidential Decree or to consultation among parties to labor relations. But analysis on the rule of legislation and void for vagueness doctrine reflected in the decision by the Constitutional Court led that argument for a theory against the principle of the legality is not reasonable. Close examination was done on a formal act of essential business agreement and necessity of prior agreement before submission of decision to the Labor Relations Commission which might have difficulties in performing work. In addition, an example agreement on hospital essential business is attached to help you understand this paper better.

Checklist method is rapid and comprehensive to evaluate in practice. Check items are commonly rated by subjective utility function; i.e., evaluator's significant judgment. Since human judgment includes fuzziness (vagueness) inherently in spite of its significance, fuzzy set theory is useful in this case. The paper illustrates a evaluation method using fuzzy checklist where check items are rated as fuzzy numbers. Pairwise comparison data is used to determine the weights of check items, since it has comparative advantage for human's fuzzy judgment. Sample of BASIC program is provided for microcomputer. When uncertainty is due to subjectivity or imprecision of data, this method can be applied to practical problems widely.

A robust and reliable learning and reasoning mechanism is addressed based upon fuzzy set theory and fuzzy associative memories. The mechanism stores a priori an initial knowledge base via approximate learning and utilizes this information for decision-making systems via fuzzy inferencing. We called this fuzzy computer architecture a 'fuzzy hypercube' processing all the rules in one clock period in parallel. Fuzzy hypercubes can be applied to control of a class of complex and highly nonlinear systems which suffer from vagueness uncertainty. Moreover, evidential aspects of a fuzzy hypercube are treated to assess the degree of certainty or reliability together with parameter sensitivity.

Successful implementation of statistical process control techniques requires for operational definitions and precise measurements. Nevertheless, very often analysts can dispose of process data available only by linguistic terms, that would be a waste to neglect just because of their intrinsic vagueness. Thus a hybrid approach, which integrates fuzzy set theory and common statistical tools, sounds useful in order to improve effectiveness of statistical process control in such a case. In this work, a fuzzy approach is adopted to manage linguistic information, and the use of a Chi-squared control chart is proposed to monitor process performance.

Keeping in view the expediency of soft sets in algebraic structures and as a mathematical approach to vagueness, in this paper the concept of lattice ordered soft near rings is introduced. Different properties of lattice ordered soft near rings by using some operations of soft sets are investigated. The concept of idealistic soft near rings with respect to lattice ordered soft near ring homomorphisms is deliberated.

A great deal of research has been made to model the vagueness and uncertainty in information retrieval. One such research is fuzzy ranking models, which have been showing their superior performance in handling the uncertainty involved in the retrieval process. In this study we develop a new fuzzy ranking model based on the user preference. Through the experiments on the TREC-2 collection of Wall Street Journal documents, we show that the proposed method outperforms the conventional fuzzy ranking models.
