The purpose of this paper is to study on the architectural value in Dom-Ino system. Dom-Ino system by Le Corbusier is a structural system for effective production in terms of physical reproductivity and a modeling system from the view of formal composition. It creates planar grid with a fixed ratio, manipulates the user group, and becomes the basic construction method. Form comes out of geometrical proportion system, and grid-based plan provides regularity and order to elevation planning. Production requires standardization. Indoor space is maintained by uniformed and integrated service facilities. Dom-Ino system was a transitional step of the Modulor system which was created by Le Corbusier in 1945 and composes of and equivalent proportional system. The fact that the numerical proportion system is the one of appropriate design methods implys a progressive concept that architectural configurations are controlled by the technology of that time. And also the system is one of the object type of Corbusier's housing architecture.

This thesis aims at understanding Le Corbusier's architecture through study of proportion. Based on the analysis of these texts, four elements - geometry in the outline, diagonal regulation lines in the facade, arithmetic rhythm in the structure, composition in the inner space - were listed. Through these four proportional systems. ten houses of 1920's, designed by Le Corbusier were analysed. The Le Corbusier's proportional system can be classified by two different purposes ; aesthetics and utility standardization for the mass production was reflected. In the later period, the proportion system of 1920's has changed through the process of self-contradiction. But the concept of the golden section and the human scale was reflected on Modulor, which Le Corbusier created in 1940's. Therefore, Le Corbuiser's notion of proportion for harmony of architecture has consistent meaning throughout all of his works from the 1920's.

In this study, we make an effort to find a method to acquire sensitive information when sensitive populations are consisted of several clusters that vary in size. We suggest and systemize the theoretical validity for applying RRT(Randomized Response Technique) to PPS(Probability Proportional to Size) sampling method and derive the estimate and it's variance of the proportion of sensitive characteristic of population by using the suggested method. We compare the efficiency of the suggested technique by two-stage equal probability sampling. We examine practical aspects of the suggested method of RRT by PPS sampling through field survey.

There has been no enough consistency about the question of 'Is it possible for golden section to be applied to product design\ulcorner'In addition, There has been no near answer about 'What is proportion\ulcorner and 'How can proportion be approached\ulcorner About this matter, this study identified various types of proportion through experiment design and consumer surrey. According to the results of this study, various and different types of proportion exist in product design and therefore, proportion in product design couldn't be considered by one-dimensional aesthetic element. This kind of study about the types of proportion could give an good answer abort the matter of 'Is it possible for golden section to be applied to product design\ulcorner'and it's expected practically to give a useful insight to the approach of Product design in Which proportion is considered. In addition, preferred proportion structure is different according to the consumer characteristic, successful design strategy such as niche market penetration could be performed if designers classify consumer characteristic systematically.

This study analyzed military personnel survivability in regards to offensive operations according to the scientific military training data of a reinforced infantry battalion. Scientific battle training was conducted at the Korea Combat Training Center (KCTC) training facility and utilized scientific military training equipment that included MILES and the main exercise control system. The training audience freely engaged an OPFOR who is an expert at tactics and weapon systems. It provides a statistical analysis of data in regards to state-of-the-art military training because the scientific battle training system saves and utilizes all training zone data for analysis and after action review as well as offers training control during the training period. The methodologies used the Cox PH modeling (which does not require parametric distribution assumptions) and decision tree modeling for survival data such as CART, GUIDE, and CTREE for richer and easier interpretation. The variables that violate the PH assumption were stratified and analyzed. Since the Cox PH model result was not easy to interpret the period of service, additional interpretation was attempted through univariate local regression. CART, GUIDE, and CTREE formed different tree models which allow for various interpretations.

컴퓨터 시스템의 성능이 발전하면서 동시에 실행되는 프로그램의 수도 증가하게 되었다. 이로 인해 자원을 두고 경쟁하는 프로세스들의 우선순위에 따라 분배되는 자원의 양을 세밀하게 조절하는 기능이 필요하게 된다. 우선순위에 따른 자원의 비례배분 알고리즘에 대한 연구가 많이 있었고, 이를 바탕으로 대부분의 자일을 관리하는 운영체계들도 개발되었다. 하지만 가상메모리 자일에 대해서는 자원의 할당량의 모호함과 프로세스가 사용할 메모리 필요량이 예측불가능하기 때문에 적은 연구가 이루어졌을 뿐이다. 본 논문에서는 프로세스가 단위 작업을 수행할 때 발생하는 페이지폴트의 양이 프로세스의 우선순위에 반비례하는 것으로 가상 메모리에 대한 비례배분 개념을 정의 하고, 프로세스 마다 메모리에 대한 요구 형태가 다른 환경에서 이를 가능하게 하는 페이지대치 알고리즘을 제안한다. 제안한 페이지대치 알고리즘을 리눅스 커널상에 구현한다. 구현된 페이지대치 알고리즘을 사용하면 우선순위가 높긴 프로세스가 우선순위가 낮은 프로세스에 비해서 페이지폰트를 적게 발생하고, 그 발생량은 반비례 관계에 있음을 보인다.

The sovereign state has the right to engage in self-defense or war with the approval of the Security Council when it receives an invasion of territory from a foreign country. War is conducted under the principle of the necessity and proportionality of self-defense. In case of cyber attack, proportional countermeasure must be made through attack means and effect analysis, and cyber weapons need to be classified for this purpose. Therefore, this study aims to provide a rational and legitimate response according to the necessity and proportionality of the self - defense right by suggesting definition and classification criteria of cyber weapons. In this study, cyber weapons were defined as "means of collecting, attacking, and protecting information using cyber technology in the cyber space according to military objectives. Based on existing weapon systems and public cyber weapons cases, cyber weapons were classified as (1) cyber weapons for information gathering, (2) cyber weapons for attack, and (3) cyber weapons for protection. We suggest the considerations for applying the proportional response according to this functional classification. In order to guarantee the principle of proportionality to cyber attacks in the future, the classification study based on the cyber weapon effect should be conducted. This study has conducted an exploratory study on the classification of cyber clusters which constitutes one axis of the proportionality principle.

The Eudoxean theory of Proportion is correlated with 'Dedekind cut' with which Dedekind defined the real number system in modern usage. Dedekind established a firm foundation for the real number system by retracing some of Eudoxus' steps of over two thousand years earlier. Thus it should be quite worthy that we separate Greek inheritance from the definition of Dedekind, However, there is a fundamental difference between Eudoxean theory of proportion and Dedekind cut. Basically, it seems impossible for Greeks to distinguish between the distinction between number and magnitude. In this paper, we will consider how the Eudoxean theory of proportion was related to Dedekind cut introduced to prove the Dedekind's real number completion and how it influenced Dedekind cut by looking at the relation between Eudoxos's explication of the notion of ratio and Dedekind's well-known construction of the real numbers.

우리나라의 변동비반영시장(CBP)은 자동발전제어(AGC)의 제공수준에 관한 정량적 평가방법을 수립되지 않아, 동 서비스의 제공과 직접적으로 관계없는 에너지 공급량에 비례하여 공급대가를 지불하고 있다. 이에 따라 전력거래소는 시장효율 향상을 위한 제도개선의 일환으로 발전기별 이행성과 및 기여도를 반영하는 AGC 정산체계를 수립하였다. 새로운 정산체계에서 발전기별 AGC 이행성과와 기여도는 각각 계통의 기대출력에 대한 실제출력의 통계적 상관계수와 EMS의 제어참여율로 결정된다. 본 논문은 AGC 정산체계의 개선방안에 관한 세부내역 및 근거를 설명하고, 사례분석을 통해 방법론의 유효성을 입증하고 있다.
