현재 시험 중심의 역사 교육으로 인해 10 대 연령층에서 한국사에 대한 관심이 감소하는 추세라고 한다.[1] 이에 대한 해결 방안으로 역사적 인물의 MBTI 및 위치 기반 인증 서비스를 활용한 애플리케이션을 제안함으로써 한국사에 대한 관심을 높이고 문화재 접근성 또한 개선하고자 한다.

The U. S. government has a long history to classify and manage governmental records which are created, collected, and preserved for itself. During the colonial period before the independence, the U. S. mostly practiced the maintenances of secret records and restrictions of access to the records following a long convention without any specific legal authority. Since establishment of the U. S. Constitution, the government had kept secret records on the basis of constitutional authority. However, the U. S. government began to take shape the secret records management system when it participated in the World War I, which required the system to reflect the needs in reality to manage drastic increases in important military and foreign relation documents. The World War II made the U. S. government strengthen its secret records management system, and its conception of secret records management system at that time has sustained until now. It can be said that the current secret records management system of the U. S. government continues to be managed by constitutional authorities and the executive orders which are opt to change. This article intends to review the secret records management system of the U. S. from the initial history of the U. S. to the Cold War. To understand its system of secret management, the paper investigates the U. S. secret records management history by dividing into three periods: the period of establishment of its tradition(the Colonial era~just before the WWI); the period of taking shape of its system (the WWI~the WWII); and the period of current conception of its system. The criteria of these divisions are created based on the differences of the laws relevant to the secret records and the application methods of secret management system in reality.

As time is rapidly changing, the culture to represent an era is getting more subdivided and complex. Due to cultural diversity, the influence, cause, characteristics which could be understood in individual field centered by space in the past cannot be understood now only by the viewpoint of one field, and it has become difficult to predict and correspond to the change of the future. With the development of information and knowledge delivery system, various cultural contents to form a space are being created and lapsed, but there are a lot of parts which cannot be explained or understood by only one point of view. To inspect these situation, this study is aimed to draw the cultural and technical causes that became the influence with Suwon Hwaseong, a traditional space with historical superiority, analyze the key factors that became the main factor to form the space, and consider the importance of the related factors. Suwon Hwaseong is a new town formed by the order of King Jeongjo. Suwon Hwaseong at that time was a space with the will and effort of many people who dreamed a new era, and it has a meaning of varoius time ans space as historical facts and cultural values as well as the progress and development of scientific technology. The unstructured data technique which is applied as the method of analysis in this study can be said to be a new value judgement and viewpoint in interpreting the space. Therefore, this study is a new trial to provide a frame for multilaterally interpreting the various traditional space and culture of Korea from the past to the present.

The history of finding solutions of linear equations went back to some thousand years ago, and has been steadily developed to solve systems of higher degree polynomials. The method to eliminate variables came into use around the 17th and 18th century. This technique has been extended to the resultant theory that was laid in the 19th century by outstanding mathematicians as Euler, Sylvester, and B$\acute{e}$zout. In this paper we discuss the historical reflection about the development of solving system of polynomials. We add a special emphasis on E. B$\acute{e}$zout who gave the first account on the resultant which is a generalization of discriminant and Gauss elimination method.

This study is about the law of cosines. It dealt with its historical origin and the developmental process of the age of Greece, Islam and Modern age. Especially, we tried to find out how the extension of the law of cosines for spherical triangles and tetrahedron from the law of cosines for plane was done. On the basis of this analysis, we investigated how the law of cosines was generated and proved it through the logical demonstration and mathematical induction. This made us find out the mathematical meaning of mathematical concepts.

The SNS post records were not studied by some or essential characteristics of personal records. Until now, Studies on SNS post records have focused on research on technical characteristics, and studies on identity and online space have been rare. This study argued that SNS postings are records that reflect online identity and that SNS postings are meaningful in recreating events related to online and online. This study also suggested the composition of self-history from an epic self-image of events experienced by individuals from their own historical point of view, and argued that SNS post records perform an important role in the process. To this end, the media characteristics of SNS and the way individuals are used were analyzed together.

The relations between the two countries, Korea and Japan, are growing worse because of the matter of distorting korean history, absurd remark for aggressive war, and claiming Tokto by Japan. At the point of time, I research the distorted instances of Korean history in Japanese game. The distorted instances of Korean history in game are existed in any countries' game such as China and The West; however, Japanese game takes distorted instances too far. Teenagers in the interior of a country and people from other countries easily access the distorted game because of the development of Internet and promoted cultural exchange among nations so it is necessary that systematic countermeasure should be set.

Metropolitan Subway, tke volume of station, distance between station is short. when the demand is concentrated during moving peak periods, the Headway that than Line Headway in which Station Headway is applied to Station Capacity computation be. The factors to determine the Station Headway have a fixing Price of the machine and the Dwell time. Other factors aye decided already or fixing price but the Dwell time that change according to demand cause the biggest effect at Station Headway. After analyze constituents that influence to Station Headway in this study calculated correct Station Capacity drawing estimating dwell time model that change according to demand.

건축에 있어서 이론과 실제의 관계 문제는 오랫동안 건축 담론에 대한 주요 대상이 되어왔다. 이는 건축에서의 발전이 역사적으로 동시대의 사회적, 문화적, 경제적 환경의 진화와 더불어 진행되어 왔기 때문이며, 건축작업 선상에서 대두되는 이론과 실제의 관계와 맥락성이 건축의 주체성에 매우 중요한 요소로 여겨지기 때문이기도 하다. 1960년대부터 불거진 포스터모던주의의 사고적 영향은 건축분야의 의미와 가치에 있어서 학문과 실무분 야에서 새롭게 재조명되기 시작하였고, 기존 건축고유의 영역을 벗어나, 역사, 이론, 비평, 기술 및 디자인 분야로 확장되어 새롭고 다양한 접근 방법과 그 방식에 대한 고민을 추구하기 시작하였다. 건축작업에 중요한 근거를 제시해주는 비평적 사고를 유지하기 위하여, 이론적인 아이디어에서 실질적인 실무로서의 투사방법, 그리고 그 사이의 절충을 지속하기 위함은 특히 현대사회에서 더욱 복합적이며 다면적인 질문이 되고 있다. 이 논문은 건축의 투사 방법에 있어서 현대 건축가들이 자신들의 이론적인 관점과 그 관점을 건축적으로 가시화 시키는 관계성을 관찰하고, 어떻게 본인만의 논리와 프로세스를 추구하고 지속하는가에 대한 점을 연구하는데에 그 목적이 있다.

적률법(method of moment)이란 변수 X의 멱승에대한 기대치를 이용하여 분포의 성질을 알아보는 방법이다. 여기서 적률법이 이용되어진 역사적 배경을 소개하고, 3차 적률들의 선형적 성질을 비교하였다. 먼저, Kagan이 입증한 표본평균에 관한 3차 표본적률의 선형적 성질과 Bayesian 경우에 3차 사후적률(posterior moment)과 사후평균(posterior)의 선형성을 소개하였다. 그리고, 자연지수족(natural exponential family)아래서도 표본평균에 관한 3차 표본적률의 선형성을 알아보기 위해 단순함수(simple function)의 형태로 유도하였으며, 정규분포인 경우에 적용시켜 보았다.
