When imaginary numbers were first encountered in the 16th century, mathematicians were able to calculate the imaginary numbers the same as they are today. However, it required 200 years to mathematically acknowledge the existence of imaginary numbers. The new mathematical situation that arose with a development in mathematics required a harmony of real numbers and imaginary numbers. As a result, the concept of complex number became clear. A history behind the development of complex numbers involved a process of determining a comprehensive perspective that ties real numbers and imaginary numbers in a single category, complex numbers. This came after a resolution of conflict between real numbers and imaginary numbers. This study identified the new perspective and way of mathematical thinking emerging from resolving the conflicts. Also educational implications of the analysis were discussed.

본 논문은 인용분석에 대한 비판적 견해를 살펴봄으로써 인용분석에 대한 미래를 전망하고자 하였다. 구체적으로는 인용분석의 발전과정을 기술의 발전, 도구의 개발, 사회적 환경이라는 측면에서 검토하고, 이러한 발전을 주도하였던 규범이론을 설명하였다. 그리고 미시사회학적 견해에서 제시되었던 인용분석에 대한 비판을 가정의 한계와 데이터의 문제로 구분하여 검토하였다.

The transit-oriented development (TOD) model can effectively help to solve urban problems and promote sustainable urban development. The United States and Japan are widely considered the earliest two countries to start TOD practices; however, the origins of TOD models in the two countries were different. The TOD practices in the two countries formed distinct characteristics, yet their differences have been underexplored. This study aims to grasp the characteristics of the TOD model in the two countries through a systematic comparative analysis of 10 typical cities in the United States and Japan that have adopted the TOD model. This paper compares the case cities' three key aspects of the TOD model: public transit system, spatial form, and land use, and summarizes the characteristics of TOD models in the two countries from a city-level perspective, to help deepen the global understanding of TOD.

기업이 수립한 전략이 효율적으로 실행되기 위해서는 적절한 조직문화가 뒷받침되어야 한다. 이는 전략실행에 적합한 조직문화를 갖추고 있을 경우 기업성과가 더욱 높아질 수 있음을 의미한다. 따라서 본 연구에서는 경쟁전략과 조직문화간의 적합성이 균형성과표 관점별 성과에 미치는 영향에 대해 분석해 보고자 한다. 경쟁전략을 원가우위전략과 제품차별화전략, 조직문화를 위계 합리문화, 합의 개발문화로 대별하고, KOSPI 상장 제조기업을 대상으로 설문조사를 통해 수집된 122부의 설문자료를 바탕으로 경쟁전략과 조직문화간의 적합성이 균형성과표 관점별 성과에 미치는 영향에 대해 실증 분석한 결과를 요약하면 다음과 같다. 첫째, 원가우위전략을 추진하는 기업의 경우 위계 합리문화의 적합성이 높은 것으로 나타났다. 구체적으로 원가우위전략과 위계 합리문화의 적합성이 높을수록 학습과 성장 관점 성과를 제외한 나머지 균형성과 표 관점별 성과가 더욱 높은 것으로 나타났다. 둘째, 제품차별화전략을 추진하는 기업의 경우 합의 개발문화의 적합성이 높은 것으로 나타났다. 구체적으로 제품차별화전략과 합의 개발문화의 적합성이 높을수록 모든 균형성과표 관점별 성과에 긍정적인 영향을 미치는 것으로 분석되었다. 본 연구는 기업이 수립한 전략의 성공적 추진을 위해서는 조직구성원의 신념 및 행동에 변화를 야기할 수 있는 조직문화를 전략에 적합하게 형성하는 것이 중요하다는 것을 실증적으로 규명해 보았다는데 연구의 의의를 찾을 수 있겠다.

Research on information systems and software engineering has often neglected behavioral effects, which may play a role in decision making on software development. The current study addresses this issue by empirically investigating the behavioral roots of over-requirement in the context of a software development project via an experiment. The negative phenomenon of over-requirement refers to specifying a software system beyond the actual needs of the customer or the market, which overload the system with unneeded features. The research question addressed here is whether over-requirement is due in part to the emotional involvement of developers with the software features they developed because of behavioral effects. Previous studies have demonstrated that under the endowment, I-designed-it-myself, and IKEA effects, people become emotionally involved and overvalue physical items that they respectively possess, self-design, or self-create. The findings of our experiment show that participants over-valued features they were assigned to be responsible for, to specify, or to construct, thereby confirming that the three behavioral effects play a role in software development decisions and affect over-requirement. Thus, the study contributes to software development research and practice from the behavioral economics perspective, highlighting the roots of over-requirement.

The master plan of forest land management proposes forest watershed management that considers regional characteristics in order to overcome the problem of uniform forest land management. In order to manage the forest watersheds in Gyeonggi-do, this study classified 1,823 forest watersheds in Gyeonggi-do and attempted to understand their characteristics. It conducted a factor analysis and cluster analysis from the perspective of conservation value and development pressure using forest land indicators. In terms of conservation value, three factors were drawn: the topography factor, vegetation factor and public service factor, while in terms of development pressure, three factors were drawn: the easiness of development factor, economic benefits factor and development activity factor. Using these factors, forest watersheds were divided into three clusters in terms of conservation value while they were divided into three clusters in terms of development pressure. Using the results of the cluster analysis from a conservation-development perspective, the forest watersheds were classified into nine different types, and the characteristics were identified by each type. It is judged that the factors and clusters drawn as a result of the research accurately reflect the present conditions of Gyeonggi-do, and the nine types of forest watersheds have clear characteristics according to each type, which are judged to be utilized in forest management in the future.
