Purpose Though many information systems researchers have made various attempts to investigate the relationship between information technology capability and firm performance from diverse perspectives, we have not come to a conclusion yet with some mixed results. In this research, focusing on the adoption of Enterprise Resource Planning (ERP) systems by firms as a proxy measure for information technology capability, we reexamine whether the association is significantly positive. Design/methodology/approach Previous research on this topic had some limitations to the samples and analysis method. Some research focused only on the 1990s or early 2000s, and other studies failed to adequately compare the impact of ERP adoption on firm performance between the treatment group and the control group. In this research, extending previous analysis approaches with the matched sample comparison of IT leaders and the control group, we attempt to apply propensity score matching in combination with difference-in-difference analysis with a sample of Korean firms that adopted ERP systems in the late 2000s. We match ERP adopters and non-adopters with propensity score matching and compare their financial performance with difference-in-difference estimation between the pre- and post-adoption periods. Findings According to our analysis, we find no positive and significant relationship between ERP adoption and firm performance in profit ratios. This research shows that, contrary to the era of proprietary information systems, standardized information systems today have no additional competitive advantages over competitors.

This study was conducted to identify key success factors of the Agricultural Cooperative Federation. We classified the divisions of regional agricultural cooperatives into high performers and low performers to investigate differences in environmental stability, resource capacity, resource flexibility, differentiation strategy, and low-cost strategies between high and low performers. Empirical analyses revealed that high performers are superior to low performers in resource capacity, resource flexibility, differentiation, and low-cost, but there was no difference in environmental stability between high performers and low performers. Internal factors including resource and strategy attributes affect business performance, but external factors such as environmental attributes do not. Moreover, resource flexibility generates the broadest gap between high performers and low performers. These results indicate that resource flexibility is the key factor leading to success of organizations with greater competitors because it enables them to overcome their disadvantageous competitive position in size and resources through complete exploitation of resources across divergent business areas owing to its flexibility. Our contribution is that we draw the key success factors of the Agricultural Cooperative Federation through an empirical approach.

If we try to define the concept of beauty in the large sense, as Kant and Chaung-tzu all agree, It can not be fixed in the one sense, but whose connotation and denotation should be extended infinitely. In this sense, I would like to say that the beauty is liberty. Aesthetics of Kant is oriented toward subjective and reflexive dimension, while that of Chuang-tzu is oriented toward natural and practical one. The difference between aesthetics of the two philosophers begins from their philosophical methodology. If the transcendental methode which is proper to Kant's philosophy prefers to discriminate and devide everything especially from dichotomic viewpoint by langage. But Chuang-tzu' methode called Za-Mang criticizes such a dichotomic division and langage itself. Even so, the two in the long run agree as to the foundation of beauty. But Kant's liberty is one of will or transcendental, meanwhile that of Chuang-tzu is based on recognize the fact that we are all production of nature. according to Chuang-tzu, in the great beginning, there was non-being. It had neither being nor name. The One originates from it. When things obtain it and come into existence. As the One, Tao is in the excrement and urine. Everything is under the constant flux. All species have originative or moving power. Although the universe is vast, its transformation is uniform. Because all things are one. Vacuity, tranquillity, mellowness, quietness, and taking no action characterize the things of universe at peace and represent the ultimate of Tao and virtue. The material was transformed to be form, form was transformed to become life, and now life has transformed to become death. A basic principle of Chuang-tzu's art is expressed in the phrase "taking off clothes and squatting down bare-backed". The key of Chuang-tzu's aesthetics is to dedicate to the expression of inner spirit instead of physical verisimilitude, and painting should be a spontaneous and instantaneous flow of the brush. Kant's concepts such as "disinterested" and "purposiveness of nature" seem to imply in the long run the unification of nature and human being which is fundament to Chuang-tzu's aesthetics.

Today, changes in the environments surrounding companies are so uncertain that corporate entrepreneurship should be activated to enhance the competitiveness of firms and to improve their profitability. In particular, The practice of entrepreneurship by small and medium sized enterprises (hereafter SMEs) is suggested as an important factor for the enhancement of competitiveness of firms. In this context, this study examined the effects of the organizational climates on the entrepreneurship activities of SMEs in Korea and China. The data obtained from 300 SMEs in Korea and China through questionnaire surveys were analyzed. The results demonstrate that the organizational climates have significant positive effects on SMEs in the countries belonging to emerging markets such as Korea and China. However, the practice of corporate entrepreneurship could be manifested in diverse forms, such as innovation or strategic renewal, and the effects of organizational climates were shown to sightly different effects on the corporate entrepreneurship activities. In addition, SMEs in Korea and China, which belong to common cultural areas, did not show any statistically significant difference in organizational climates in general. Furthermore, the effects of these factors did not show significant differences in general. However, SMEs in Korea with more flexible organizational structures and higher job autonomy were shown to be more advantageous in practicing corporate entrepreneurship than those in China. The results of the study provide meaningful implications for SMEs in Korea in terms of the efforts that should be made to enhance their competitiveness, implement innovation, and achieve comparative advantages over China.

This study investigated school mathematics curriculum of the State of Georgia in the United States focused on the 'number and operation' and 'algebra' domain. On the basis of its understanding, this domain was compared and analyzed with school mathematics curriculum of Korea. In doing so, this study explored its plans and procedures and established a frame of comparison for the curriculums between the two countries. The most noticeable difference between the former and the new curriculum in mathematics for Georgia schools is the use of performance standards. A performance standard has four components: a content standard, illustrative tasks, examples of student work, and a commentary for teachers. This study focuses on the content standard and according to the results of the present study, Korea focuses on the formal and systematic mathematical knowledge on the basis of sound understanding of certain mathematical terms or concepts. On the other hand, the State of Georgia curriculum tends to deal with the content which can be understood more intuitively, flexibly, and naturally through the experience, aquisition, and furthermore interpretation based on the concrete manipulation and technological devices.

The purpose of this study is to set up the situated learning model for computer education and to investigate which method has better effect on the students' computer skill and learning attitude among the situated learning model and the traditional learning model. The result of this study is as follows. In order to investigate the effect of the students' learning attitude, students had been tested on six factors: the Understanding, the Interest, the Achievement, the Concentration, the Applicability, and the Spontaneity. As for the Understanding, the traditional learning model has better effect on students than the situated learning model. But the situated learning model was much superior in the other factors to the traditional learning model. Next, it had been examined how much students improved their computer skills under the situated learning model and under the traditional learning model. The study showed that the traditional learning model resulted in a little bit higher scores than the situated learning model. However, it was a great success to find out that the situated learning model is superior in the students' learning attitude to the traditional learning model.

이 글에서는 해외지역연구에 있어 세계와와 관련한 여건 변화, 지리하계의 동향, 그리고 21세기의 새로운 지역연구에 지리학의 역할이 어떠하여야 할 것인가를 살피고자 한다. 해외지역연구는 2차대전 이후 미국을 중심으로 발달하였다. 냉전기에 세계적 우위를 유지하고 국익을 보호하기 위하여 외국 현지어 구사 능력을 포함한 해외 정보 수요가 늘어 지역연구의 발달을 보게 된 것이다. 이러한 배경 때문에 지역연구는 개성기술적(ideographic)성격을 띠게 되었다. 요즘에는, 지역연구가 주로 초국적기업, 국제 경영대학원 등을 중심으로 이루어 지고 있다. 새 지역연구는 해외시장정보 수집 등 경제적 동기로 이루어지고 있어, 경제적으로 편향되는 취약점이 있다. 세계화는 요즘 하계의 화두(話頭)로, 세계 경제와 사회에 일고 있는 이 변화를 바로 이해하는 것은 향후 지역연구의 방향을 정립하는데 매우 중요하다. 세계화는 세계 어디서나 똑같이 일어나는 동질적인 현상이 아니라, 매우 다양하고 여러 의미가 담긴 현상이다. 마치 동전에 양면이 있듯이, 세계화는 수렴과 분화를 동시에 일으키고 있는 것이다. 따라서, 국경을 개방하고 장애를 없애 하나의 동질적인 세계시장환경을 지향하는 신자유경제 논리에 바탕한 지역연구는 설득력이 약하다. 지리학이 지역연구에 기여하기 위해서는 다음과 같은 노력이 계속되어야 한다. 첫째, 해외지역을 이해하려면 공간(space)과 장소(place)연구가 필수적이라는 점을 인식하고, 둘째, 인간과 환경의 상호작용 관점에서 지리적 차이를 파악하려는 노력이 필요하다. 셋째, 지리학은 이론정립 노력을 계속해야 하며, 넷째, 그 이론들은 해외지역의 현장답사와 정보수집을 통하여 검증되어야 한다. 지리학은 일찍부터 도시, 농촌 등 미시적 수준의 연구를 수행해왔기 때문에 경험적 연구에 강하다. 다섯째, 정부와 기업 등 조직에 대한 지리학적 연구가 이루어져야 할 것이다. 경제활동 분포에 대한 조직의 역할, 소유권에 대한 정부의 규제, 생산 조직의 환경 영향 등의 연구가 그 예이다. 여섯째, 지리학의 발달을 위하여 국가, 국제적 학술 기구를 활용하는 전략이 필요하다. 국제지리학연합(IGU)에서 개발한 지리교육과정, 미국National Research Council에서 세계지리에 밝지 못한 국민을 대상으로 펴낸 지리서 등이 그 사례이다. 지역연구는 사회과학 이론과 문화연구가 서로 접목되도록 새롭게 방향이 설정되어야 하며, 지리학의 인간-환경 연구 전통이 여기에 기여할 수 있을 것이다. 그러나 지리학의 역할이 효율적이기 위해서는 지리학 자체의 담론을 다시 확립해야 한다. 지리학계에서 지난 20여년간 추구해왔듯이 일반적 법칙을 지향(nomothetic)하는 접근법을 활용해야 하며, 여타 사회과학 및 환경과학과도 긴밀한 관련을 유지할 필요가 있는 것이다.

인류에 필수불가경한 에너지는, 석유, 석탄과 같은 화석연료에 의한 염에너지와 수력, 조력, 파력, 풍력 등의 비열에너지가 있으나, 에너지이용량중 열에너지가 절대적 우위를 점하고 있다. 열에너 지는 전기한 화석연료 뿐만 아니라, 태양집, 태양열발전소와 같은 태양열에너지의 직접이용, 핵에 너지의 열에너지전환, 지열, 해수의 온도차이용등, 열에너지는 다량하면서 막대한 에너지량을 보 유하고 있는 실정이지만, ㅈ로 석유자원에 의존하여 온 것이 현상이다. 그러나, 1970년대 초기에 엄습한 석유파동이래, 세계적으로 에너지위기감에 사로잡혀, 세계각국은 탈석유화에 따른 에너지 의 다양화와 에너지절약이 감소되게 되었다. 연료절약에 관하여 말하면, 에너지이요의 효율화를 적극적으로 도모함에 있어서 열에너지이용에 관한 평가방법에 새로운 검토가 가해져서, 더 합 리적인 평가방법의 확립이 필요하게 되었다. 이를 위해서는 종래의 열역학 제1법칙에 의한 열 에너지의 양적평가 뿐만 아니라, 열역학 제2법칙에 의한 질적평가의 중요성이 인식되어, 유효에 너지(available energy) 또는 엑세르기(Exergie)의 개념이 위상되고 있다. 물론 이 개념을 적용 하여 열역학 제2법칙에 의한 해석에 따른 일정산(heat balance)에 있어서 전혀 새로운 결과가 얻어지는 것은 아니지만, 지금까지는 열정산에 있어서 열역학 제1법칙에 의한 평가방법만이 강 조되어, 열역학 제2법칙에 의한 평가방법은 거의 도외시되어온 것이 실정이며, 우리나라에서 발 간되는 열역학에 관한 도서에서도 이에 관한 검토 내용이 거의 찾아볼수 없거나, 가령 언급된 것이 있다 하더라도 그 내용이 간략하여 그 중요성이 경시되어온 것이 사실이다. 그러나 열역학 제2법칙에 의한 에너지정산에 의하여, 제1법칙에 의한 것보다 열에너지의 합리적이고 또한 유 효한 과학적평가가 가능하게 되어, 장치나 기기의 개선에 구체적이면서 합리적인 지침이 주어 지게 된다. 그리하여 이들 개념과 방법의 소개가 필요하다고 생각되어, 지금부터 우리들이 잘 아는 용어를 사용하여 해설을 서로 하기로 한다.
