M. C. Jensen과 W. H. Meckling이 쓴 'The Nature of Man' 논문의 핵심은 역시 REMM(Resourceful Evaluative Maximizing Model)이다. REMM이라는 용어는 새롭지만 개념은 200년 이상의 연구와 경제학과 사회과학과 철학적 토론의 산물이라는 것이다. REMM에서의 핵심은 Resourceful이다. 어떤 이론이나 정책이건 어떤 가정과 한계가 있다는 의미로 사용할 수도 있다. 재무관리의 모태인 경제학에서 지금까지 사용된 모델은 고전 경제학시대부터 일관되어 왔던 추상적 의미의 이익(효용)극대화 모델이다. 재무관리는 그 목적이 궁극적으로 인간의 소비선호체계를(people's consumption preference) 극대화 하는 것이고, 한정된 자원(scare resources)을 시간에 따라 어떻게 배분하여 효용(utility)을 극대화하는 것을 중심과제로 삼고 있다. 효용의 극대화를 위한 자원배분은 생산자원을 어떻게 배합하여 가치생산을 극대화하느냐 하는 생산에의 배분문제와 생산된 재화 및 서비스를 사람들의 욕구충족을 최대로 하는 소비에의 배분문제로 나눠 생각해 볼 수 있다. 그런데 적어도 재무관리에서는 후자는 다루지 않고 가치생산의 문제만 다룬다. 이러한 가정하에서 재무관리의 목표와 이에 따르는 재무관리이론(가정)의 전개는 가치창조와 소비에의 배분을 통한 효용의 극대화를 다루는 경제학의 이론을 답습함으로 일부 혼선을 불러올 수 있다. 위험에 대한 재무담당자(투자자)의 태도를 재무관리의 입장이 아니라 경제현상 전체에 해당되는 입장에서 다루므로 각 각의 교재마다. 투자자의 부 또는 수익에 대한 효용과, 위험과 수익에 대한 무차별곡선이 달리 표현되고 있다. 재무관리 책에서는 재무관리의 가정하에서 투자자의 수익에 대한 효용, 그리고 수익과 위험에 대한 무차별곡선이 정립되어야 할 것이다.

Cohesion refers to the degree of the relatedness of the elements in a module, and it is widely accepted that the module of higher cohesion is easier to understand, maintain, and reuse. Recently, several cohesion metrics have been proposed to measure the cohesiveness of classes in an object-oriented program. However, the existing cohesion metrics do not consider the characteristics of dependent instance variables that are commonly used in a class and, thus, do not properly reflect the cohesiveness of the class. This paper presents an approach for improving the cohesion metrics by considering the characteristics of the dependent instance variables in an object-oriented program. To demonstrate the importance of the dependent instance variables, a case study has been conducted on a class library.

Purpose: Understanding elbow biomechanics is necessary to understand the pathophysiologic mechanism of elbow injury and to provide a scientific basis for clinical practice. This article provides a summary of key concepts that are relevant to understanding common elbow injuries and their management. Materials and Methods: The biomechanics of the elbow joint can be divided into kinematics, stability and force transmission through the elbow joint. Active and passive stabilizers include bony articular geometry; soft tissues provide joint stability, compression force and motion. Results and Conclusion: Knowledge of elbow biomechanics will help (i) advance surgical procedures and trauma management, (ii) develop new elbow prostheses and (iii) stimulate future research.

There are three significant drawbacks in extant fuzzy rule-based expert system languages. First, they lack the functionality of composite object inference. Second, they do not support fuzzy reasoning semantically easy to understand and conceptually simple to use. Third, knowledge representation and reasoning style of their model have a great semantic gap with those of current database models. Therefore, it is very difficult for the two models to be seamlessly integrated with each other. This paper provides the formal specification of a fuzzy object inference model to solve the three drawbacks. GIS(Geographic Information System) application domain is used to demonstrate that our model naturally models complex GIS information in terms of composite objects and successfully performs fuzzy inference between them.

Philosophical discussion and ethical approach have been crucial aspects in the rational decision-making of heritage conservation. This study analyses why and how they play an important role in determining the quality of conservation practice. It highlights the key concepts of conservation philosophy and ethics, as well as their relationship, in order to establish a constructive platform through which researchers may understand the role and importance of conservation philosophy and ethics. In conclusion, this study provides a set of recommendation for the government, academic experts, and conservators which will allow them to become actively involved in improving the quality of philosophical and ethical knowledge in the field of conservation.

Phantasy is the psychic reality in which drive, sadism and anxiety are represented and constructed. It is one of important metapsychological concepts of the psychoanalysis which explains the formations of symptoms, internal psychic structure, and the mutual relationship between internal subjective world of man and external world. Through the understanding of phantasy we can approach the man's unconsciousness and fathom the structure of the subject itself. Especially S. Freud and M. Klein's psychoanalysis give us the deep insight into the phantasy, on the basis of which we can investigate the cause and structure of the pathological phenomena of the man.

Tuberculosis continues to cause an unacceptably high toll of disease and death among children worldwide. Whereas intense scientific and clinical research efforts into novel diagnostic, therapeutic, and preventive interventions have focused on tuberculosis in adults, childhood tuberculosis has been relatively neglected. However, children are particularly vulnerable to severe disease and death following infection, and those with latent infection become the reservoir for future transmission following disease reactivation in adulthood, fuelling future epidemics. Therefore, it is very important to understand the significance, diagnosis and treatment of latent tuberculous infection to decrease a future disease burden of tuberculosis. Unfortunately, these concept still have not fully implicated in Korean National Tuberculosis Control Program, it should be engaged and enforced as soon as possible.

In this paper we solve various triangle construction problems related with radius of escribed circle using algebraic method. We describe essentials and meaning of algebraic method solving construction problems. And we search relation between triangle construction problems, draw out 3 base problems, and make hierarchy of solved triangle construction problems. These construction problems will be used for creative mathematical investigation in gifted education.

Cohesion refers to the degree of the relatedness of the members in a class and it is widely accepted that the higher the cohesion of a module is, the easier the module to understand and maintain. Recently, several cohesion measures have been proposed to measure the cohesiveness of classes in an object-oriented program. In this paper, we propose an approach to improving the existing cohesion measures by considering the impact of write dependencies between class members. We have developed a cohesion measurement tool for supporting our approach and describe a case study performed with a C++ class library.

효소는 생명 현상을 구현하는 단백질 촉매인데 그 동안 효소의 촉매 반응 속도는 Michaelis-Menten(MM) 모델로 대부분 설명되어 왔다. 그러나 MM 모델은 실험으로 측정된 단일 효소 반응시간의 확률분포 모양을 설명할 수 없다. MM 모델에 반응계수의 정적 무질서 개념을 도입한 효소 반응 모델도 기질 농도에 따라 변화하는 효소 반응시간의 통계적 요동을 설명하지 못한다. 우리는 단일 효소 반응시간의 통계적 요동이 기질에 따라 변화하는 양상을 설명하기 위해 효소 반응을 구성하는 개별 화학반응을 단순히 푸아송 과정이 아닌 갱신과정(renewal process)으로 확장한 효소 반응 모델을 제안한다. 우리는 이 단일 효소 반응 모델과 기질에 따른 효소 반응시간 분산 변화 데이터를 비교하여 효소-기질 복합체의 지속시간 분포를 간단한 형태로 얻어내었다. 또한, 이 정보를 토대로 전산모사를 수행하여 효소 반응시간의 확률분포를 얻어내고, 실제 실험 결과 및 기존 이론들과 비교하였다. 뿐만 아니라 단일 효소 반응시간의 확률분포를 연속 시간 임의의 보행자(continuous time random walker)의 대기시간 확률분포(waiting time distribution)로 대응하면, 평균 제곱 변위가 시간에 따라 단순히 증가 하지 않는 고분자의 특이 수송(anomalous diffusion) 현상도 정량적으로 설명할 수 있었다.
