Economists have long been involved in various studies, theoretical and empirical, on the economic gains from innovative activities and as their outcome, intellectual properties. In Korea, however, research in this field has experienced rather slow progress, partly due to the lack of data availability and the awareness of its importance. This study attempts to measure the economic impact of patents on market value of firms from a microeconomic point of view. Analyses are performed to examine the ex-ante market valuation of patent acquisition activities by investigating the effect of patent acquisitions on daily stock prices as well as on annual market values. The study on the effect of a disclosure of granted patents on daily stock prices reveals that the economic value of a firm's patent acquisition is fairly high. The study on listed firms also reveals that a firm's patent registration stock has a positive and statistically significant effect on its year-end market value. Therefore, it can be concluded that the analysis performed in this study supports the validity of Korea's current patent system. The result, however, does not guarantee the optimality of current system. Studies on various aspects of intellectual property should follow to shape the system into a socially optimal one.

Geography textbooks often have treated the world as a collection of independent nations. Also, many scholars have warned of ethnocentric bias in geography textbooks. Global education that emphasizes world interdependence and pursues global perspectives offers some possibilities to go beyond the status quo of current World Geography textbooks. The primary objective of this study is to analyze current US World Geography textbooks in terms of global education. A secondary objective is to explore a framework for rereading World Geography textbooks critically. This interpretive qualitative case study indicates that US World Geography textbooks maintain an imperialist and American-centered perspective. Especially, the case of Korea shows that other places and people are underrepresented through dichotomy, negative attitude and exclusion, misconception and stereotyping, and simplification in textbooks. Therefore, we need to detect conscious and unconscious fallacy and bias, to understand the world view and experiences of underrepresented people, and to deal with controversial global issues from diverse perspectives through global perspectives and post-colonial perspectives of global education.

This case report is a treatment of patient with hemophilia A and autism. The patient's chief complaint was treatment of dental caries on entire dentition and he has an impacted mesiodens located on the apex of the upper right primary central incisor. The patient was consulted with pediatrician and anesthetist about the detailed discussion of the complexities of hemorrhagic disorder. Because he had some problems of behavior management and bleeding, the treatment was done under the gerneral anesthesia. The following results were obtained. 1. Consult with the patient's physician and hematologist about the replacement therapy and bleeding tendency. 2. For the severe hemophiliac child who requires extensive or surgical treatment, general anesthesia may be indicated for the comprehensive care. 3. For the hemophiliac child who has a behavior management problem due to autism and other defects, general anesthesia may be considerable. 4. Care must be taken during dental procedures not to causing a bleeding. 5. Local hemostatic methods must be acquired for the emergency state. 6. Neve prescribe aspirin or non-steroidal anti-inflammatory drugs such as ibuprofen, indomethacin, and phenylbutazone. These drugs affect platelet aggregation and exaggerate the bleeding defect. 7. Do not be afraid of hemophiliac patient, and never compromise quality of dental care.

Ectopic eruption of the maxillary first permanent molar means that the molar erupts out of the normal position and is arrested in its eruption by the second primary molar. This local eruption disturbance results in a premature atypical resorption on the distal part of the second primary molar. In most irreversible cases, the second primary molar is lost prematurely, either by spontaneous exfoliation or by extraction, In cases of doubt as to whether the eruption is of the irreversible type or not, careful radiographic observation period for a few months would be valuable in evaluating the possibilities of the tooth's freeing itself. The purpose of this study was to determine the characteristics and occurrence of the ectopic eruption of the maxillary first permanent molar. A descriptive, observational, retrospective study was done using the radiographs of 25 conseutive patients, who were in the first phase of mixed dentition. A method was designed to evaluate the amount of pathologic resorption of the second maxillary primary molar and the mesial angulation of the first permanent molar. The study showed that the most important etiologic factor was the eruption path or mesial angulation of the first permanent molars relative the chosen reference lines.

This paper provides an overview of political ecology, a body of theory that focuses on the links between political and economic inequality on the one hand, and environmental degradation on the other. Adopting a tripartite classification scheme that identifies three political ecology traditions -'classical', 'democratic' and 'poststructuralist'- the discussion shows the need for a move within the poststructuralist tradition away from a narrow and quasi-idealistic focus on discourse to a more robust philosophical engagement with ontological and epistemological issues grounded in Gilles Deleuze's development of Nietzschean materialism. From there. the author draws on numerous examples from Canada, and surveys the available literature on 'bioregionalism', a relatively new intellectual tradition evolved from the North American environmental social movements of the 1970s and 1980s. The so-called 'bioregional approach' stresses that administrative units need to reflect (rather than transect) eco-geographical and cultural features. Bioregionalism is described and assessed as a potential pragmatic research framework for geographers and other planners wishing to respond proactively to the call for a revamped, poststructuralist political ecology. The paper concludes that a bioregional approach to political ecology avoids the weaknesses identified by certain critics, provides scope for consideration of fundamental philosophical ideas, and as such, represents a practical development of a poststructuralist political ecology.

This research reviews how tourism geography studies in Anglo-American tradition have evolved since 1930s. The purposes of the research are two fold. One is to analyze the change of tourism geographies research trends in terms of research approach and major research themes. The other is to bring out the lessons from the research results for the development of Korean tourism geographies research. For these purposes, the selected papers and texts have been analyzed according to four research approaches: (1) empiricist approach, (2) positivist approach, (3) humanist approach, and (4) critical social theory approach. The major research themes are the explanation of destination through descriptive research in empiricist approach, spatial analysis and evolutionary research in positivist approach, tourist behaviour and place identity in humanist approach, and tourism and consumption in critical social theory approach. It is expected that the development of Anglo-American tourism geographies study will continue in the future because of the growth of tourism industry, the close relation of tourism and geography in nature, and the active contribution of tourism geographers.

To examine the locality of Busan is a precondition of examining documenting localities of Busan. What is the locality of Busan and how can I explore the locality of Busan? These are the research questions of this thesis. Memory is fundamental in making an identity. So local memory is fundamental in making locality. Understanding relations between memory and identity, the author explored the locality of Busan by analyzing memories of Busan. To analyze memories of Busan is to examine historical figures of Busan and Cultural Properties of Busan which are on the website of Busan metropolitan city. The results are as follows : According to the analysis of historical figures of Busan, there are no confucius scholars who came from Busan. However in the age of civilization, Busan has produced some talented people by way of receiving a modern education. According to the analysis of Cultural Properties of Busan, Jung-gu(中區) and Seo-gu(西區) and Yeongdo-gu(影島區) are the spaces of migration. Dongnae-gu(東萊區), Suyeong-gu(水營區) and Saha-gu(沙下區) and Gijang-gun(機張郡) are the spaces of settlement. Dong-gu(東區) has changed from a space of settlement into a space of migration with the opening of the Busan Port as a momentum in 1876.

21세기를 맞이하여 대학도서관은 정보기술의 도입, 업무내용의 변화, 이용자의 요구변화등 급격하게 변화하는 새로운 환경에 직면해 있다. 본 연구는 한국의 대학도서관 조직구조의 현황에 대한 분석과 함께 다양한 조직이론들과 정보환경의 변화에 기초해서 도서관조직을 활성화시키기위한 개념적인 조직모델을 제시하고자 한다. 한국의 대학도서관은 거의 10년동안 법적인 제약과 조직내외의 환경적인 한계 등으로 인해 전산화시스템의 도입, 도서관부관장의 임명, 그리고 도서관과 컴퓨터 센터와의 통합시도와 같은 약간의 변화외에는 거의 변화가 없었다. 전형적인 한국의 대학도서관은 수서, 기술서비스, 열람과 참고봉사 부문으로 조직되었다. 여기서 수서 기능을 기술서비스의 부문으로 간주한다면, 본 연구의 대상인 대학도서관 114개관 중 95개관(82.5%)이 전통적인 도서관조직의 형태인 기술서비스와 공공서비스 부문으로 조직된 것으로 나타났다. 본 연구에서는 전통적인 도서관조직의 문제점들을 급복할 수 있는 21세기의 개념적인 대학도서관 조직모델로서, 네가지 부문 - 서비스 부문, 서비스지원 부문, 기술지원 부문, 그리고 통합·조정부문-을 대학도서관의 개념적인 기본 구성요소로써 제안하였다. 그러나 모든 도서관의 서비스나 업무과정에 대해 적합한 잉상적인 조직구조는 없으며, 조직의 재조직과정은 도서관의 형태와 목적, 업무과정에 따라 매우 다양하다. 따라서 도서관의 재조직화는 환경의 변화에 따라 끊임없는 과정이 될 것이며, 도서관조직의 성공은 이러한 변화에 적응할 수 있는 개인과 조직의 역량에 달려있다고 하겠다.대한 순서에 있어서 차이가 있다. 4) 도서관에 대한 태도에 있어서 두 집단은 상이한 입장을 보이고 있다. 학자들의 과반수는 중요 정보원으로서 자신의 개인장서를 활용하며, 도서관의 장서 및 그 조직방법에 대해서도 별로 만족하지를 못하고 있다. 반면에, 실무가들은 도서관에 대하여 비교적 만족하며 따라서 도서관에 대한 이용도도 높다. 5) 두 집단 모두 보조인을 적극적으로 활용하지 않으며 사서의 도움을 받는 경우도 극소수에 불과하다. 이러한 조사결과를 기초로 하여 볼 때 법률전문직을 둘러싼 정보환경을 개선하기 위하여는, 인쇄된 일차적 정보자료의 검색방법등을 개선하고, 나아가서는 법령과 판례정보를 위한 효율적인 시스템을 구축하며, 뿐만 아니라 이용자의 요구에 충분히 대처할 수 잇는 도서관으로 변화되는 것이다. 이와 함께 가장 중요한 것은 법과대학과 사법연수원에서 법학 연구방법에 관한 강좌를 개설하여 각종 법률정보원의 활용 내지 도서관 이용방법에 관하여 교육하는 것이다.글을 연구하고, 그 결과에 의존하여서 우리의 실제의 생활에 사용하는 $\boxDr$한국어사전$\boxUl$등을 만드는 과정에서, 어떤 의미에서 실험되었다고 말할 수가 있는 언어과학의 연구의 결과에 의존하여서 수행되는 철학적인 작업이다. 여기에서는 하나의 철학적인 연구의 시작으로 받아들여지는 이 의미분석의 문제를 반성하여 본다. 것이 필요하다고 사료된다.크기에 의존하며, 또한 이러한 영향은 $(Ti_{1-x}AI_{x})N$ 피막에 존재하는 AI의 함량이 높고, 초기에

Developing Mathematical Thinking has been continually emphasized in the Korean curriculum and this emphasis has demonstrated its impact on math textbooks and classes in South Korean schools. This study intends to discover how the Developmental Mechanism of Mathematical Thinking should be reflected through School Mathematics regardless of subfields of Mathematics or its levels. Finally, this study concluded that the Developmental Mechanism of Mathematical Thinking is being reflected on School Mathematics. However, more research in certain areas needs to be done. Through analyzing textbooks, it is certain that the Developmental Mechanism of Mathematical Thinking is being reflected on School Mathematics. Moreover, it appears that students are able to develop new concepts using Developmental Mechanism of Mathematical Thinking. Mathematical Thinking is a subject that many scholars and mathematicians have taken an interest in. Especially with the math curriculum in Korea, designing and implementing classes that would help students develop their mathematical thinking are increasingly being emphasized. This study defines what mathematical development mechanism is, and based on this definition, it further analyzes the math textbook of the revised 2007 curriculum. As a result, textbook developers and math teachers should examine and analyze the concepts that learners need to acquire and how they develop. Further, this study not only presents the concepts students are expected to acquire, but also looks at the flow in which concepts have been introduced to students. It concludes that activities that can help students have an idea of what they are going to learn in the future should be provided during class time.

Biologist must have to do 2DGE biological experiment for Protein Search and Analysis. This experiment coming into being 2 dimensional image. 2DGE (2D Gel Electrophoresis : two dimensional gel electrophoresis) image is the most widely used method for isolating of the objective protein by comparative analysis of the protein spot pattern in the gel plane. The process of protein spot analysis, firstly segment protein spots that are spread in 2D gel plane by image processing and can find important protein spots through comparative analysis with protein pattern of contrast group. In the algorithm which detect protein spots, previous 2DGE image analysis is applies gaussian fitting, however recently Watersheds region based segmentation algorithm, which is based on morphological segmentation is applied. Watersheds has the benefit that segment rapidly needed field in big sized image, however has under-segmentation and over-segmentation of spot area when gray level is continuous. The drawback was somewhat solved by marker point institution, but needs the split and merge process. This paper introduces a novel marker search of protein spots by watersheds-based hierarchical threshold, which can resolve the problem of marker-driven watersheds.
