I present a theoretical analysis of the charismatic leadership and the follower's role. I distinguish between two types of charismatic relationships and present general propositions about how followers' self-concepts may dertermine the type of charismatic relationship they form with the leader. I conclude by suggesting further the study.

외환금융위기 이후 구조조정에 의한 고용불안이 사회적 이슈가 되면서 90년대 후반부터 고용불안정에 관한 연구가 꾸준히 계속되어 왔다. 그러나 대부분의 국내 연구들은 가설검증에 의한 개별적인 연구결과를 제시하고 있을 뿐 포괄적이고 체계적인 연구는 이루어지지 못하였는 바, 이는 고용불안정 연구를 위한 통합모형이 개발되지 못하였기 때문이다. 따라서 본 연구에서는 선행연구로부터 고용불안정에 관한 제 가설을 설정하고, 이들 가설에 대한 국내실증연구결과를 면밀하게 분석하여 고용불안정의 선행요인 및 결과에 관한 명제를 도출하고 통합모형을 제시하였다.

본 연구에서는 중학교 2학년 도형의 성질 단원의 증명학습을 세 단계로 나누어 설문을 통하여 학생들이 증명학습에서 겪는 어려움을 조사하였다. 설문 분석 결과 학생들은 증명학습에서 증명의 의미를 이해하지 못해 명제의 참을 판단하는 정도의 간단한 추론도 하지 못할 뿐만 아니라 제시된 증명을 읽고 그것이 증명하려는 명제의 가정과 결론을 파악하지 못한다. 이는 학생들이 명제의 가정과 결론의 의미와 역할을 명확히 이해하지 못하는데서 비롯된다. 따라서 학생들에게 명제의 가정과 결론의 의미와 역할에 대한 지도에 좀 더 역점을 두는것이 필요하다.

This paper attempts to delineate and analyze the relationship between organizational search activities and organizational ambidexterity. A growing number of studies confirm that organizational ambidexterity is important for firm survival and long-term prosperity. However, research on how to achieve ambidexterity is still limited. To date, structural separation, contextul ambidexterity, and top management team attributes are proposed and examined as major antecedents of organizational ambidexterity. In this paper, I argue that orgnizational search may influence ambidexterity through its effect on exxploratory innovation and exploitative innovation. Since little study has been paid to uncover the relationship between knowledge search and ambidexterity, I develop theoretical arguments and propose some propositions rather than examine hypotheses. The propositions developed in the study are as follows; P1: The breadth of internal search is positively associated with exploratory innovation; P2: The breadth of external search has a reverse U-shaped relationship with exploratory innovation; P3: The depth of internal search is positively associated with exploitative innovation; P4: The depth of external search has a reverse U-shaped relationship with exploitative innovation; P5: The interaction between internal search breadth and internal search depth is positively associated with organizational ambidexterity; P6: The interaction between external search breadth and external search depth is positively associated with organizational ambidexterity. Based on the above propositions, I suggest some considerations for empirical research and propose avenues for future research.

This study aims to develop propositions about the factors that influence the purchase intention of private label products. These factors are: in-store promotion, visual merchandising, store image, and customer value. This study elaborates on some of the results of previous studies that have examined the factors that influence purchase intention of private label products that have been published on Google Scholar and indexed by Scopus between 1991- 2020, to develop a proposition. This paper fills a lack of Studies which discuss purchase intention from a consumer behavior perspective. From the perspective of consumer behavior, purchase intention is influenced by three factors, namely: intrinsic factors including: consumer value, extrinsic factors including: in-store promotions, visual merchandising and store image, and consumer factors. This paper defines purchase intention as the effort and strong urge to buy a particular product in the future, the possibility of considering buying the product, the decision to rebuy the product and the desire to recommend the product. The main findings of this research are several propositions, namely: in-store promotion, visual merchandising and store image directly affect customer value and purchase intention. The following propositions are: In-store promotion, visual merchandising and store image influence purchase intention mediated by customer value.

마틴뢰프의 직관주의적 유형론의 중요 사항들을 설명하고, 그 체계의 가장 중요한 특성 중의 하나인 명제와 판단의 구분에 관해 검토한다. 1절에서 문제를 도입한 후, 2절에서 직관주의적 유형론의 명제개념은 직관주의적 명제개념의 발전된 형태임을 보이고, 3절에서는 직관주의적 유형론에서 가장 기본적인 판단개념을 설명한 후, 4절에서 직관주의적 유형론의 기본적인 추론규칙들을 설명하고 그 적용의 한 사례를 검토할 것이다. 마지막으로 5절에서, 직관주의적 유형론에서 명제와 판단의 구분이 차지하는 중요성을 부연한 후, 기초론적 체계에서 명제와 판단의 구분이 필수적인지의 문제와 관련하여, 통상적인 프레게적 구분으로부터 시작하여 직관주의적 유형론에서와 같은 구분에 이르기 위해서는 어떤 것들이 전제되거나 정당화되어야 하는지 검토할 것이다.

Logic and intuition are considered as the opposite extremes of teaching geometry, and any teaching method of geometry is to be placed between these extremes. The purpose of this study is to identify the characteristics of logical and intuitive approaches for teaching geometry and to derive didactical implications by taking Euclid's Elements and Clairaut's Elements respectively representing the extremes. To this end, comparing the composition and contents of each book, we analyze which propositions Clairaut chose from Euclid's Elements, how their approaches differ in definitions, proofs, and geometrical constructions, and what unique approaches Clairaut took. The results reveal that Clairaut mainly chose propositions from Euclid's books 1, 3, 6, 11, and 12 to provide the contexts that show why such ideas were needed, rather than the sudden appearance of abstract and formal propositions, and omitted or modified the process of justification according to learners' levels. These propose a variety of intuitive strategies in line with trends of teaching geometry towards emphasis on conceptual understanding and different levels of justification. Specifically, such as the general principle of similarity and the infinite geometric approach shown in Clairaut's Elements, we could confirm that intuition-based geometry does not necessarily aim for tasks with low cognitive demand, but must be taught in a way that learners can understand.

This paper builds a system dynamics model analyzing first mover effect and growth strategy of online retailer, a major segment of B2C e-commerce. The dynamic model in this paper is calibrated to the online book market and Yes24.com as major test cases. The model consists of eight key value chain sectors. Five of these(Users, Site Operations, Human Resources, Financial Accounting, and Fundraising) are internal to the company, and three others(Market, Financial Market, and Relative Performance) are external to the company. With the model, this paper suggests research propositions representing positive feedback loops and negative feedback loops that lead to corporate growth and limits to growth according to dynamic causal relationships among eight key value chain sectors, and simulate these propositions.

Ubiquitous computing(UC) is an emerging paradigm. Its arrival as a mainstream is expected to trigger innovative UC-driven business models (UCBMs). Currently, there is no Parsimonious methodology to analyze and provide diagnostics for UCBMs. With this research, we propose a analytical architecture that enables the assessment of an UCBM in its structural strengths and weaknesses. With value logic as the cornerstone, the architecture is composed of value actors, value assets, value context, business value Propositions, customer value propositions, value creation logics, and value assumptions. Dimensional variables are initially Identified based on the review of business model literature. Then, their significance is empirically examined through 14 UCBM scenarios, and variables that are expected to Play an important role in the UCBM assessment are decided. Finally, by analyzing the scenarios in terms of the dimensional variables, we attempted to summarize general characteristics of emerging UCBMs.

In Internet age, traditional transaction concepts are being examined in new perspectives. Electronic commerce, as a new transaction paradigm, is being paid attention to reexamine traditional marketing theories. In this study, equity is adapted to electronic commerce. We add Navigational Equity to existing equity concept: Payment and Service (Huppertz et al 1978). The research model of this study consisted of three major constructs such as equity, normative comparison of equity and consumer satisfaction in electronic commerce. Additionally, the environments of Internet navigation, which include system quality, easy for use, social pressure, playful aspects, and security check, etc. were analyzed. The propositions were drawn from the research model of this study. These propositions will be used to generate hypotheses constructing simultaneous equation model. More empirical study of future is expected.
