There are currently various types of alternative schools which has diverse goals and traits in Korea. Education suited to educational principles can't be carried out, as long as mathematics education in alternative schools is same as one in the regular schools. In this thesis the problems of mathematics education which is conducted in alternative schools for maladjusted students will be examined in three aspects of teaching contents, teaching methods, and teaching environments. And we will study about mathematics education that use mathematical history as one way of mathematics education for the alternative school students.

In a recent paper, M. Balaj [B] established an alternative principle. The principle was applied to a matching theorem of Ky Fan type, an analytic alternative, a minimax inequality, and existence of solutions of a vector equilibrium theorem. Based on the first author's fixed point theorems, in the present paper, we obtain generalizations of the main result of Balaj [B] and their applications.

In this study, a design approach based on genetic algorithm is proposed to solve the manufacturing cell design problem considering alternative process plans and alternative machines. The problem is formulated as a 0-1 integer programming model which considers several manufacturing parameters, such as demand and processing time of part, machine capacity, manufacturing cell size, and the number of machines in a machine cell. A genetic algorithm is used to determine process plan for each part, part family and machine cell simultaneously.

In this paper, we attempt to analyze consumer preference for the alternative-fuel vehicles based on data from a stated preference using the conjoint analysis. Five possible fuel types (gasoline, diesel, CNG, LPG, Hybrid (electricity+gasoline)) are covered in conjoint cards. To estimate and analyze consumer preference, discrete choice model is used. Specifically, Bayesian mixed logit model is used. Based on estimating results, we discuss the business strategy and policy for the alternative fuel vehicle.

Obesity is a serious medical disorder because it can cause a myriad of health problems, such as heart disease, hypertension, and adult-onset diabetes. While conventional medical treatment for obesity has limitations, there is enormous public enthusiasm for complementary and alternative treatments of obesity. This article reviews currently commonly used complementary and alternative therapies for obesity, such as medicinal herbs, nutritional supplements and acupuncture. Beneficial effects and possible adverse effects associated with these treatment are discussed.

This study reviews (i) the (dis)advantages of two major semantic theories of focus, i.e., the Alternative Semantics (AS) and the Structured Meaning Theory (SM), and (ii) the hybrid analysis consisting of these two theories proposed by Krifka (2006). After pointing out a problem of this hibrid analysis, this study attempts to show the third alternative, i.e., the theory of identificational predication for focus can solve this problem.

Alternative materials for the visually disabled are very important factors for accessing and using information, dissolving the knowledge information gap, social participation and integration. Nevertheless, since alternative materials have been produced, until recently, even under the voluntary efforts of the braille library and the financial support of local governments, the scope of the materials is restricted to literary materials and hobby books, duplicated in title, and limited in format. In this study, we investigated and analyzed the cases of domestic and international library and related organizations' alternative material production and the current state and perception of alternative materials by applying the survey method to special libraries for the visually disabled and the visually disabled. Based on these results, we added suggestions for the improvement for alternative material production and utilization.

We developed emission factors for alternative fuels used in cement industries in Korea and also estimated reduction in emissions of greenhouse gas (GHG) by the use of alternative fuels. Emission factors for GHG of waste tire, waste plastic, waste oil and RDF were estimated to be about 89, 78, 77 and 95 ton $CO_2$/TJ respectively. When compared with previous studies, most of the results showed similar trends. The calorific value estimation and elemental analysis for energy source were implemented in order to estimate the exact emission factors and the reduction of GHG emissions using alternative fuel. In the case of 'A' company, $CO_2$ emission from alternative fuels was about 4% lower than that of bituminous coal only. Also in case of company 'B', $CO_2$ emission from alternative fuels was about 1.4% lower than that of only bituminous coal. In Germany and Japan, alternative fuel is not regarded to be fuel consumption in cement industry. When applying this rule, the emission reductions were about 4.3% for company 'A' and 6.3% for company 'B'. The results of this study may be considered as a useful information for developing strategies in reducing GHG emissions.

Purpose: This study aims to understand effective brand naming process of an optical shop brand by a research of brand naming process of optical shop through creation of alternative. Methods: It investigated brand naming process such as character abstraction, target grasp, naming direction set, naming development and etc of an optical shop. It also looked into characteristics of alternative creation patterns such as words mix, typifier, sentence making, part words mix and etc and then, it investigated brand naming examples. Results: Creation of alternative is a phase of brand naming which has to be refined on the basis of creation of abundant alternatives and then to be developed to a brand name. This study suggested examples of brand names of optical shops which were made and adopted by creation of alternative. Conclusions: Creation of alternative in brand naming complies with concept, and it has systemic process and objective selection as an effective way in association of brand and searching words. It is necessary to have brand naming works through creation of alternative for the purpose of individual and strong brand name with desirable association and differentiation of an optical shop.
