In this study, factors influencing the parking policy compliance (i.e. levying a garage option on car buyers) were identified, and then, were applied to the theory of planned behavior. To find out the influence of factors and their path, the study built a parking policy compliance model using structural equation modeling. The independent variables such as attitude, subjective norm, perceived behavioral control had positive effects on the parameter describing the efforts to secure his garage, but the parameter impact on the dependent variable was not significant. In the end, the independent variables affected the dependent variable was not significant. The perceived behavioral control utilizing regulations had positive effects on the parking policy compliance behavior, but past behavior such as street parking and prowling to find a free parking space had a negative effect on parking policy compliance behavior.

The aim of this paper is to clarify the difference between the concept of deduction-induction and Aristotle's concept of syllogismos-epagoge. First, Aristotle does not use the expression 'invalid syllogismos'. But a valid deduction is distinguished from a invalid deduction in modern logic. Second, from Aristotle's point of view syllogismos is paralleled by epagoge. Because syllogismos is equivalent to epagoge in logical form. But a disturbing lack of parallelism exists between deduction and induction by which the standards for establishing inductive conclusions are more demanding than those for deductive ones. Third, instructors in introductory logic courses ordinarily stress the need to evaluate arguments first in terms of the strength of the conclusion relative to the premises. Accordingly, students may be told to assume that premises are true. But Aristotle does not assume that premises are true. A syllogismos start from the conceptually true premise and a epagoge start from the empirically true premise.

In learning environment at mathematics education, prove and refute are essential abilities to demonstrate whether and why a statement is true or false. Learning proofs and counter examples within the domain of limit of sequence is important because preservice teacher encounter limit of sequence in many mathematics courses. Recently, a number of studies have showed evidence that pre service and students have problem with mathematical proofs but many research studies have focused on abilities to produce proofs and counter examples in domain of limit of sequence. The aim of this study is to contribute to research on preservice teachers' productions of proofs and counter examples, as participants showed difficulty in writing these proposition. More importantly, the analysis provides insight and understanding into the design of curriculum and instruction that may improve preservice teachers' learning in mathematics courses.

본 연구는 MM(1963)에 의하여 시작된 기존의 기업가치와 자본구조에 대한 연구 방법과는 달리, Rao(1987), Howe(1995), Brealey-Myers(1996)등을 중심으로 시도되어 온 시장가치 대차대조표(MVB/S)를 이용한 기업가치와 자본비용의 통합적 분석방법을 소개하였다. 그리고 MM(1963)에 가정을 추가함으로써 변형된 기업가치 모형과 자본비용에 대한 연구방법을 시도한 Modigliani(1988), Miles-Ezzell(1980)와 Taggart(1991)의 연구가 MVB/S를 이용하여도 동일하게 적용할 수 있음을 증명하였다. 따라서 본 연구는 MM(1963)의 명제들로부터 유도되는 관계식인 가중평균자본비용과 무부채기업의 자기자본비용과의 관계(MM명제III)와 부채사용기업의 자기자본 비용과 무부채기업의 자기자본비용과의 관계(MM명제II)를 Modigliani(1988), Miles-Ezzell(1980)와 Taggart(1991)의 가정하에서 MVB/S를 이용하여 각각 유도하였다. 그리고 MVB/S를 이용하여 유도된 자본비용들간의 제관계식이 이들의 연구결과와 동일함을 증명하였다. 나아가 개인소득세가 존재할 경우에 무위험주식의 도입을 통하여 기업가치모형을 유도하고 이를 바탕으로 자본비용들간의 제관계식을 유도하고 아울러 베타분석도 실시하였다.

지금까지 카테고리가 없던 혁신적 신제품이 시장에 진입하는 데는 없던 시장을 새로 만들어야 하기 때문에 많은 저항에 부딪힌다. 이를 극복하는 방안을 본 연구에서는 시장창조 전략이라 하고 구체적으로 11 가지 제안명제를 제시하고 있다. 먼저 저항을 극복하기 위해 도입기와 성장기를 보다 세분화하여 시장형성, 강화, 확장으로 나눌 필요가 있다(제안명제 1). 다음으로 시장형성, 강화, 확장의 각 단계별 저항을 극복하기 위해 가치이동, 장벽이론, 캐즘이론, 팬텀이론, 허수잠재성, 메가마케팅 및 홍보, 스키마이론 등에 근거한 7 가지 제안명제를 준수할 필요가 있다. 끝으로 여러 저항 극복을 위해 혁신적 신제품과 신제품에 모두 적용되는 마케팅전략인 제안명제 9, 10, 11을 준수할 필요가 있다.

In this study, we divided the teaching and learning of proof into three steps in the demonstrative geometry of the middle school mathematics. And then we surveyed the student's difficulties in the teaching and learning of proof by using of questionnaire. Results of this survey suggest that students cannot only understand the meaning of proof in the teaching and learning of proof but also they cannot deduce simple mathematical reasoning as judgement for the truth of propositions. Moreover, they cannot follow the hypothesis to a conclusion of the proposition It results from the fact that students cannot understand clearly the meaning and the role of hypotheses and conclusions of propositions. So we need to focus more on teaching students about the meaning and role of hypotheses and conclusions of propositions.

The purpose of this study is to introduce the Levying Garage Option on Car Buyers which has become operative firstly in Korea, and to suggest the way to activate the system, hearing the view of Jeju residents with positive and negative function of parking. Levying Garage Option on Car Buyer is the system to apply a law for establishing garages to all of vehicles. Especially this is proposed to correct the disorder of Local street night parking, to improve the fine view of street, and to recover the original function of street to residents. To make this system successful there should be separate solutions at the densely built up area as a result of survey. This study conduct the Logistic Regression Analysis for and against the system. If the more residents approve the system, we should concern about the several solutions such as easing the distance between the garage and street, regulating, and special plan for an apartment house, etc. The suggestions are as follows. First, the policy needs to ease the distance between the garage and street gradually. Second, the Jeju government need to offer the residents the incentive such as reduce or exempt the tax and make them establish the private parking lot with supplying the low interest loan. Third, there should be connected with the project to break up the fences of their houses.

본고에서는 신(新)성장이론과 자원우위 내지 동태적 역량에 관한 연구결과를 토대로 전환기의 경제자유화 과정이 경쟁의 기반을 어떻게 재규정하고 전략 또는 조직의 변화를 어떠한 방식으로 유발시키는가를 설명하고자 한다. 그러한 변화는 기존의 조직유형과 경제자유화 이후에 탄생된 새로운 기업들로 기술되었다. 본고에서는 동태적 경쟁과 마케팅 혁신의 추동력에 관한 몇 가지 명제를 도출하였다. 그러한 명제들은 개발도상국은 물론 우리 나라와 같은 신흥공업국에 이르기까지 지역과 소득수준을 초월하여 광범위한 범위에 걸쳐 적용될 수 있는 시장지향적 제도개혁과 마케팅 행동상의 변화간의 동태적 상호작용으로 야기되는 주요 정칙성에 초점을 두었다. 제시된 명제들은 제도개혁이 전환기의 경제적 환경에 어떻게 영향을 미치는가에 관한 신(新)성장이론의 관점과 제도개혁에 대한 기업차원의 대응과 이에 따론 제도적 변화간의 관계를 설명하려는 자원우위 내지 동태적 역량에 관한 이론과 실증적 연구결과에 근거한 것이다.

This paper investigates the effectiveness of Real-Name System on Internet, which has been applied to some Internet service provider bulletin boards in Korea. The goal of the Real-Name system on the Internet is controlling expression of slanderous or abusive language. The effectiveness of the regulation is dependent on the people's perceptions and attitude toward to the legislation. This empirical study examines the antecedents that affect the perceptions and attitude toward the regulation. Further, we investigate the relationships among variables such as internet public sphere participation, attitude to the regulations, and intention to choose detours. Results of regression analysis show that the younger and the more progressive individuals are, the more they oppose the implementation of the law. Also, it was found that people who have more political interest and participate more actively in public sphere via internet, tend to oppose the law. Structural equation models reveal that participation in online public sphere drives negative attitudes about the regulation. In addition, people with negative perceptions about the law tend to choose the detours such as 'cyber asylum' and 'service asylum'.

디자인 개발단계에서 가장 창조적인 부분은 아이디어 발상 단계로 아이디어를 구체화하는데 매우 중요한 부분을 차지한다. 많은 그래픽 디자이너들이 활용하고 있는 연상자극법이나 발상전환법, 정보조합법 등은 발상과정에서 초기 키워드를 제시하는데 효과적이지만 컨셉까지 도출해내는 과정에서 한계성이 있다. 컨셉으로 발전시키기 위해서는 핵심 키워드도 중요하지만 문장으로 정리되어야 보다 효과적인 비주얼로 표현할 수 있기 때문이다. 본 연구는 키워드를 문장으로 만들어내는 발상툴에 대한 것으로 국문수사법을 활용하여 명제를 만들고 연상단어를 명제에 대입해 문장으로 만들어 내는 발상법을 제시한다.
