Library communities face many problems and limitations in describing alternative format materials based on the traditional MAchine Readable Cataloging (MARC) structure. To address these problems, this research proposes an XML-based descriptive metadata framework that establishes general but fundamental bibliographic aspects of various alternative format materials by providing core elements that are essential in describing these materials. Different from existing bibliographic structures, the proposed metadata framework can represent a fundamental descriptive structure by establishing four upper-level categories, 17 core elements, and 10 sub-elements in a hierarchical structure optimized to alternative format materials. By using this principal descriptive structure, the proposed metadata framework can guide different institutions in the creation of bibliographic records for these materials in a consistent way. It is also expected to address the difficulties in describing alternative format materials in library communities and enhance the information accessibility of individuals with various types of disabilities. In addition, the proposed metadata framework is an alternative approach which functions as a mediator between heterogeneous characteristics of alternative format materials and the existing bibliographic structures in library communities.

The purpose of this paper was to provide an overview of the existing literature on online visual merchandising and to propose an alternative theoretical framework in which online visual merchandising research can be conducted. Two streams of research including the e-tail service quality literature and the store environment literature from environmental psychology perspectives were reviewed in the context of online visual merchandising. An impression formation paradigm from social psychology was adopted to establish the alternative framework to supplement the existing online visual merchandising research and generate deeper insights into the online visual merchandising phenomenon.

The conventional framework of welfare politics, based on class concepts, tends to fail in explaining the recent social changes. Theoretical response from the social science diverges into two blocs. One is the postmodernist approach that denies possibility of structural cleavage; the other is the alternative trial that seeks to find various kinds of cleavages. The former approach is to be rejected because there is few empirical supports for it. The latter is too sparse to be applied to the studies of welfare politics that requires a comprehensive analysis. This study starts from critical investigation of such approaches, aiming at providing a theoretical framework that combines merits of existing studies on welfare politics. The theoretical framework of three statuses of welfare rights and duties, which is to be presented as an alternative to the conventional class counterpart, does not only underscore the expansion of welfare rights but also the burden of welfare duties. Hence, it can comprehensively subsume complex existence of interest cleavages of welfare politics. To make a long story short, individual interest, related to the welfare state, will effect individual attitudes toward the welfare state and their ways of political support.

메타데이터 요소들 사이의 매핑에 기반한 현재의 메타데이터 상호운용성 접근방식이 지닌 한계를 극복하기 위해, 본 연구에서는 마스터 데이터를 활용한 메타데이터 상호운용성 접근방식을 제안하고 있다. 이는 메타데이터 요소가 아닌 요소의 값을 기준으로 동일한 값을 지니는 요소를 마스터 요소를 중심으로 통합하는 방식이다. 이를 위해 마스터 요소 프레임워크를 구축하여 메타데이터 요소들을 계층적인 형태로 의미적으로 통합하고, 이를 기반으로 메타데이터 레코드 사이의 상호연결을 확보함으로써 메타데이터 상호운용성을 확보할 수 있다. 이는 메타데이터 상호운용성을 확보하기 위한 대안적인 방법으로 활용될 수 있다.

The present work proposes the potential fuzzy framework, based on fuzzy set theory, for supporting decision-making problems, especially, selection problems of a best design in the area of nuclear energy system. The framework proposed is composed of the hierarchical structure module, the assignment module, the fuzzification module, and the defuzzification module. In the structure module, the relationship among decision objectives, decision criteria, decision sub-criteria, and decision alternatives is hierarchically structured. In the assignment module, linguistic or rank scoring approach can be used to assign subjective and/or vague values to the decision analyst's judgment on decision variables. In the fuzzification module, fuzzy numbers are assigned to these values of decision variables. Using fuzzy arithmetic operations, for each alternative, fuzzy preference index as a fuzzy synthesis measure is obtained. In the defuzzification module, using one of methods ranking fuzzy numbers, these indices are defuzzified to overall utility values as a cardinality measure determining final scores. According these values, alternatives of interest are ranked and an optimal alternative is chosen. To illustrate the applicability of the framework proposed to selection problem, as a case example, the best option choice of four design options under five decision criteria for primary containment wall thickening around large penetrations in an advanced nuclear energy system is studied.

This paper investigates the nature of the discourse domain involved with focus sentences. The major theories of focus including Roothian Alternative Semantics are critically reviewed: Alternative Semantics takes a contradictory attitude toward the truth conditional aspect of free focus. The truth conditional differences are treated as a pragmatic inference, while they are captured by the semantic mechanism, that is, the alternative sets generated by focus constructions. In addition, the alternative sets are ad hoc since they are generated only for focus constructions. This paper attempts to show that the alternative sets introduced by foci in the framework of Alternative Semantics are neither necessary nor sufficient for an analysis of focus. It is argued that the domain sets simply provided by the model itself suffices for a proper analysis of focus constructions.

We consider the simultaneous selection of part routes for multiple part types in Flexible Manufacturing Systems (FMSs). Using an optimization framework we investigate two alternative route assignment policies. The one, called routing mix policy in the literature, specifies the optimal proportion of each part type to be produced along its alternative routes, assuming that the proportions can be kept during execution. The other one, which we propose and call pallet allocation policy, partitions the pallets assigned to each part type among the routes. The optimization framework used is a nonlinear programming superimposed on a closed queueing network model of an FMS which produces multiple part types with distinct repeated visits to certain workstations. The objective is to maximize the weighted throughput. Our study shows that the simultaneous use of multiple routes leads to reduced bottleneck utilization, improved workload balance, and a significant increase in the FMS's weighted throughput, without any additional capital investments. Based on numerical work, we also conjecture that pallet allocation policy is more robust than routing mix policy, operationally easier to implement, and may yield higher revenues.

A framework alternative to that of classical slope stability analysis is developed, wherein the soil mass is treated as a continuum and in situ soil stresses and strengths are computed accurately using inelastic finite element methods with general constitutive models. Within this framework, two alternative methods of stability analysis are presented. In the first, the strength characteristics of the soil mass are held constant, and the gravitational loading on the slope system is increased until failure is initiated by well-defined mechanisms. In the second approach, the gravity loading on the slope system is held constant, while the strength parameters of the slope mass are gradually decreased until well-defined failure mechanisms developed. Details on the applying both of the proposed methods, and comparisons of their characteristics on a number of solved example problems are presented.

The concept of the Internet of Things (IoT) enables physical objects or things to be virtually accessible for both consuming and providing services. Undue access from irresponsible activities becomes an interesting issue to address. Maintenance of data integrity and privacy of objects is important from the perspective of security. Privacy can be achieved through various techniques: password authentication, cryptography, and the use of mathematical models to assess the level of security of other objects. Individual methods like these are less effective in increasing the security aspect. Comprehensive security schemes such as the use of frameworks are considered better, regardless of the framework model used, whether centralized, semi-centralized, or distributed ones. In this paper, we propose a new semi-centralized security framework that aims to improve privacy in IoT using the parameters of trust and reputation. A new algorithm to elect a reputation coordinator, i.e., ConTrust Manager is proposed in this framework. This framework allows each object to determine other objects that are considered trusted before the communication process is implemented. Evaluation of the proposed framework was done through simulation, which shows that the framework can be used as an alternative solution for improving security in the IoT.
