In the process of changing the Korean electoral system, various terms such as representation, majority, minority, plurality, and proportionality are not used correctly, making normative judgment on its desirable electoral system difficult. This paper clarifies the concepts and terminology related to the electoral system in order to enable proper normative discussion. First, the misuse of the names of the electoral system is reviewed. This includes the majority representative system versus the minority representative system, the single-member constituency versus the multi-member constituency, the absolute majority system versus the relative majority system, and the majority representative system versus the proportional representative system. Next, the principles of representation, proportionality, democracy, direct ballot, and equal ballot are discussed to evaluate the decisions made by the Constitutional Court of Korea. In the current electoral system of the National Assembly, the equivalence between its constituency member and its proportional representation member is very low in terms of proportionality between votes received and seats allotted. Finally, the coherence between proportional representation and other political institutions is examined. Strengthening the proportionality of parliamentary elections alone does not necessarily increase the proportionality of the entire power structure.

As various state restrictions on individual freedom were imposed during the COVID-19 pandemic, concerns have been raised that excessive infringements on fundamental rights were indiscriminately permitted based on the public interest of preventing infectious diseases. Therefore, the question of how to set acceptable limits of liberty restrictions on individuals has emerged. However, since the phenomenon of infections spreading to the population is only predicted statistically, how to deal with the risk of the infected individual as a subject of legal analysis has become a problem. In the absence of a theoretical framework of legal analysis of risk, the risk of infected individuals during the pandemic was not analyzed strictly, and proportionality review of infection prevention measures was often only an abstract comparison of the importance of public interest and individual rights. Therefore, this research aims to conduct a theoretical review on how risk can be conceptualized legally in a public health crisis, and to develop a theoretical framework for proportionality review of the risk of liberty-limiting measures during a pandemic. Chapter 2 analyzes the legal philosophical concepts of risk, which are the basis for liberty restrictions during a public health crisis, and applies and extends them to the pandemic. Chapter 3 reviews previous studies related to liberty restriction measures in the context of the COVID-19 pandemic, and points out they have a limitation that specific criteria for the proportionality review of public health measures in the pandemic have not been presented. Accordingly, Chapter 3 specifies the methodological framework for proportionality review, referring to the theoretical discussion on risks in Chapter 2. Chapter 4 reviews the legitimacy of gathering restriction orders, applying the theoretical discussion in Chapter 2 and the criteria for proportionality review established in Chapter 3. In particular, Section 4 examines logic of proportionality review in judicial precedents over the ban on gathering restrictions implemented in the COVID-19 pandemic. In analyzing the precedents, the logic of proportionality review in each case is critically reviewed and reconstructed based on the theoretical framework presented in this research.

최근 들어 다항식비례모형(RFM: Rational Function Model)은 비전문가에게 있어서 지형보정을 위한 정확도 문제를 해결함과 동시에 센서 종류에 상관없이 적용 가능한 범용적인 센서모델링 기법으로 각광을 받고 있다. 그러나 엄밀(physical) 모델이 없는 센서 혹은 위성의 궤도력 자료를 제공하지 않는 센서의 경우 다항식비례모형의 적용을 위해서는 다수의 매개변수 사용으로 인한 계수들 간의 상관성을 고려해야 한다. 이에 본 연구에서는 2차 다항식비례모형에 기초하여 전방 다항식비례모형(Forward RFM)과 상관도 분석을 통한 전방 다항식비례모형의 이른 및 위치정확도에 관한 연구를 수행하였다. 대상연구지역은 KOMPSAT(Korea Multi-Purpose Satellite)과 SPOT으로 촬영한 대전광역시와 그 주변지역으로 SPOT과 KOMPSAT 모두 상관성 분석 전에는 대략 50% 정도의 검사점에 대해 과대오차(>100m)가 얻어졌으며, 이 점들을 제외한 검사점에 대해서도 SPOT은 평균수평오차 20-24m, 평균표고오차 25m, KOMPSAT은 평균수평오차 15-24m, 평균표고오차 30m를 나타내었다. 전방 다항식비례모형에 대하여 상관성 분석을 수행한 후에는 검사점에 대한 모든 과대오차 조정결과가 소거되었고 검사점에 대해서 SPOT은 평균수평오차 8.8m, 평균표고오차 25.2m, KOMPSAT은 평균수평오차 8.4m, 평균표고오차 14.5m를 나타내었다. 최종적으로 연구지역에 대한 수치표고모형의 제작을 통해 상관도 분석을 통한 다항식비례모형의 실제 적용 가능성을 보여주었다.

응용 프로그램의 QoS를 보장하기 위하여 태스크들에게 지분을 부여하고 단위 시간동안 각 태스크에게 주어진 지분만큼의 CPU 자원을 할당하는 비례 지분 알고리즘들이 많이 연구되었다. 대부분 비례 지분 알고리즘들은 태스크 수, 지분 분포 등의 다양한 환경에 따라 동작 방식이 다르기 때문에 이러한 인자들은 시스템의 공정한 자원 할당에 많은 영향을 준다. 본 논문에서는 비례 지분 알고리즘을 동작 방식에 따라서 분류한 후, 태스크의 수와 더불어 지분의 편향성, 즉 지분 분포에 따라 QoS 공정성 결과를 분석한다. 분석결과, 비례 지분 알고리즘에서는 태스크의 수 뿐 만 아니라 지분의 분포 역시 QoS 공정성에 많은 영향을 주며, 각 환경에 따라 효율적인 최적의 알고리즘들이 존재함을 확인하였다. 제안된 분석 결과는 QoS를 지원하는 다양한 시스템에서 효율적인 비례 지분 알고리즘을 선택하여 시스템의 신뢰성을 향상시킬 수 있다.

Various cyber attacks against our society and the government are continuing, and cases and damages are reported from time to time. And the area of cyber attack is not limited to cyberspace, but it is expanding into physical domain and affecting it. In the military arena, we have established and implemented the principle of responding proportionally to enemy physical attacks. This proportionality principle is also required in the version where the region is expanding. In order to apply it, it is necessary to have a quantitative and qualitative countermeasure against cyber attack. However, due to the nature of cyber attacks, it is not easy to assess the damage accurately and it is difficult to respond to the proportionality principle and the proportional nature. In this study, we calculated the damage scale by quantitatively and qualitatively evaluating the cyber attack damage using the Gorden-Lobe model and the security scoring technique based on the scenario. It is expected that the calculated results will be provided as appropriate level and criterion to counteract cyber attack.

The body proportion of a passenger car has been changed by the demand of consumer and the market. Now the interior space proportion on a passenger car become to have the importance as the passenger space and this proportion has been changed as the new models have been developed. It didn't seems to had a unified direction or strategy in the dimensions of the domestic passenger cars on the early models, but they had a specific changes in dimensions on the later models. The proportion of the wheelbase and greenhouse can be calculated into as about 58% and 57% on the compact and sub-compact passenger cars while it is about 56% on mid-size sedan type passenger cars for thier 3-box structure body concept. The overrall proportion of the interior space is bigger on the compact and the sub-compact passenger cars than the mid-size passenger cars as the calculation shows. It can be concluded that the interior space proportion on the compact passenger cars would become larger, which is closed to 60%. And this trend would be appear on the mid-size passenger cars.

There has been a recurring call for using visual representations in textbooks to improve the teaching and learning of proportional reasoning. However, the quantity as well as quality of visual representations used in textbooks is still very limited. In this article, we analyzed visual representations presented in a Grade 6 textbook from two perspectives of proportional reasoning, multiple-batches perspective and variable-parts perspective, and discussed the potential of the double number line and the double tape diagram to help develop the idea 'things covary while something stays the same', which is critical to reason proportionally. We also classified situations that require proportional reasoning into five categories and provided ways of using the double number line and the double tape diagram for each category.

It is doubtless that product aesthetics and design are very important keys determining the success and failure in today's market environment in spite of the lack of academic model and positive research results. However, surprisingly the research of such an aesthetic has not been active. Therefore the conceptual frame of product aesthetics should be examined centering around the research of product aesthetes in other to understand consumers'aesthetic requirement and desire in the research of aesthetics of product design and the design process by analyzing that how product aesthetics anon the consumers'response and product selection, what roles the aesthetic factor of product design play in product design and what aesthetic dimension of product design is related to design product should be established.

Is golden proportion, which has been classical beauty among aesthetic rules and orders, avaiable in the present \ulcorner or Does ${\surd}$rectangle proportion replace the classical proportion \ulcorner It is a main theme in this thesis to answer the above questions. This study is basically about favorite proportion in the field of fine art, architecture and design. For this study, 2oo students participate in the answering to the questionnaire. The conclusions which result from the above surveys are as follows ; The results of the first survey is the preference of ${\surd}$2 rectangle to other ${\surd}$rectangles. The second result is the preference of golden proportion as 1 : 1.618 to ${\surd}$2 rectangle as 1 : 1.414. This survey proves that ${\surd}$rectangle proportion as modern proportion does not substitute the golden proportion with the classic proportion.

The purpose of this paper is to analyse the essence of proportional reasoning and to analyse the contents of the textbooks according to the mathematics curriculum revised in 2007, and to seek the direction for developing the proportional reasoning in the elementary school mathematics focused the task variables. As a result of analysis, it is found out that proportional reasoning is one form of qualitative and quantitative reasoning which is related to ratio, rate, proportion and involves a sense of covariation, multiple comparison. Mathematics textbooks according to the mathematics curriculum revised in 2007 are mainly examined by the characteristics of the proportional reasoning. It is found out that some tasks related the proportional reasoning were decreased and deleted and were numerically and algorithmically approached. It should be recognized that mechanical methods, such as the cross-product algorithm, for solving proportions do not develop proportional reasoning and should be required to provide tasks in a wide range of context including visual models.
