The study aims to investige how Soupjin, military training has been changed in early Joseon Dynasty. The conclusions are following these. First, Jin means military marching or attacking the enemy and Jinbeop means how to make Jin or traning but now Jinbeop indicates textbook of Jinbeop rather than practing it. Second, publishing Owijinbeop is completed as a result of continuous series of Jinbeop textbook and Owi systems are built up by military construction reorganization. Third, the total number of articles is 268 from Taejo to Seonjo in early Joseon Dynasty. They are divided into different parts according to kings. Forth, Taejo, Taejong, Munjong, Sejo, Yejong and Jungjong are the kings who take the lead of Jinbeop training directly. Among them Munjong and Sejo are highly considered that they edited and revised Sinjinbeop and tried to unify military organization. Besides Jungjong discussed Jinbeop textbooks which are published by prior kings and even make them be practiced. But after Imjinwaeran, Seonjo accepted the book Gihyosinseo by Cheokgyegwang in China and transformed our Jinbeop for protecting the country. Firth, We found that Hyangmyung and Jintoigyjak had been focused from Sejo to Jungjong. Because in this period Joseon had to find the way to protect the country from north Yeojin, But after Imjinwaeran Seonjo introduced Cheokgyegwang's Jeolgangjinbeop in China because of Japanese attacks.

On this study, the historical flow of the notation was briefly examined and the direction of mathematical investigation activity of the content of notation by analogy was explored and teaching learning materials were developed. Diverse mathematical facts were investigated on the basis of decimal system and binary system which are learned in middle school. First, the way of progressing analytic activity with algebraic material was examined. Second, on the basis of the notation which are learned in the first grade of middle school, the definition of the scale of a -notation, -a -notation, $\frac{1}{a}$notation, $\sqrt{a}$-notation was extended by analogy. The result of this study will be expected to establish the curriculum of mathematics and provide teaching and learning with the meaningful current events.

This Research is focused on ancient battle formation basing on the layout drawing of Yijinchongbang (manuals of learning military formations) in a strategy book in the late Joseon dynasty. The research topic is the principles of organic composition of battle formation and battlefield operating system by reforming the basic model of ancient battle formation. The research method is comparative analysis by reforming the battlefield operating system of types of disposition such as Obangjindisposition(Bangnjin; battle formation, Jikjin; direct battle formation, Gokjin; bend battle formation, Wonjin; round battle formation, and Yejin; keen battle formation), and Hyunmoojindo; turtle battle formation, Paljindo; all-rounder battle formation, Yookhwajindo; six flowers battle formation, Gugunjindo; nine forms battle formation. From the study results, Standoff Bombing of the battle formation in the late Joseon Dynasty basically started out from magic battle formation, but was then transformed into square, rectangle, pentagon, and circle. Also, the battle array composition used a 5-linear structure and was composed of 5 systems of circulation such as rectangle, square, diagonal, curve, and circle. The research findings elucidate the battlefield of the Joseon dynasty by establishing the real battle formation, and thus have military and academic value in suggesting possible tactics that can be used by modern training of military.

2017년 2월 카이럴 솔리톤의 발견으로 4진법 소자가 가능해지면서 인공지능 시대의 새로운 소자로 주목받고 있다. 이는 기존의 컴퓨터 시대의 소자인 2진법의 한계를 넘어서는 것이다. 플루서의 코무니콜로기(소통학)은 소통의 철학적 담론과 체계를 제시하고 있다. 콘텐츠 프로토콜에 대한 소통학적 반성은 물리학에서 발견한 4진법의 가능성을 철학적으로 설명해줄 수 있으며, 물리학의 문제 해결에 새로운 발상을 제공해 줄 수 있다. 이는 콘텐츠 기반 연구의 학제적 연구 모델이 될 수 있다.

현재 컴퓨터에서 사용되는 수의 체계는 컴퓨터의 메모리구조에서 사용하기 가장 알맞은 2진법과16진법이며 여러 프로그램들에서 효율적으로 사용되어 왔다. 그러나 어떠한 수의 체계든지 프로그램의 성질에 따라 예외적으로 드러나는 비효율적인 특성을 가지고 있다. 본 논문에서, 우리는 라우팅 관점에서의 2진법과 16진법의 예외적인 부분을 이용한 새로운 라우팅 어드레스의 표기법을 제안하며, 제안된 어드레스의 표기법을 이용한 라우팅 테이블과 라우팅 어드레스맵을 구성, 최소한의 메모리를 사용하여 센서네트워크 상에서 효율적인 Ad-Hoc 양방향 라우팅 방식을 구현하였다.

Recently, mathematics education have been emphasized on developing students' mathematical thinking and problem solving abilities. Accordance with this emphasis, dramatical changes are needed in learning mathematics not merely let alone students solve real-made mathematics problems. The project learning to explore a counterweight activity will have an effects on positive mathematical attitude(to pose problem, to have curiosity) and mathematical thinking(power 10-digit representation, 2-digit number, two representation of 3-digit number, connect exponential number and log situation) which could develop understanding problems and critical thinking.

Background: Lung cancer has become one of the most common cancers in Korea. It is important to determine the accurate histologic types and stages because of different therapeutic modlaity, especially in small cell carcinoma. This study was designed to evaluate diagnostic yields according to variable diagnostic methods in lung cancer. Methods: The records of 683 patients with a confirmed diagnosis of primary lung cancer during the period of 7 years, from January, 1986 until December, 1992 at Presbyterian Medical Center were analyzed retrospectively. Results: 1) Age and sex distributions Male: female sex ratio was 5.57:1 and age distributions were 7th decade 41.4%, 6th decade 30.2%, 8th decade 17.0%, 5th decade 7.9%, 4th decade 2.5%, 9th decade 1.3%, and 3rd decade 0.2% in decreasing order. 2) The frequencies according to histologic cell types were squamous cell carcinoma 44.7%, small cell carcinoma 23.9%, adenocarcinoma 22.8%, alveolar cell carcinoma 2.5%, large cell carcinoma 1.2%. mixed forms 1.2%, undifferenciated cell carcinoma 0.6% and malignant fibrous histiocytoma 0.2%(1 case) in decreasing order. 3) The most common locations of lung cancer were in left upper lobe and right lower lobe, and no differences of diagnostic methods according to locations were noted. 4) In central lesions, bronchoscopic examination was very accurate and frequently used diagnostic method, and in peripheral lesions, transthoracic lung biopsy(TTLB) was apparent1y accurate method. 5) The diagnostic yields of bronchoscopic biopsy, bronchial brushing, sputum cytology, transthoracic lung biopsy and transbronchial lung biopsy(TBLB) were 81.3%, 57.5%, 31.1%, 69.6% and 61.6%, respectively. 6) The concordance rates between the histologic diagnosis with bronchial brushing and sputum-cytology were 91.3% and 98.4%, respectively. 7) It was appropriate in lung cancer to repeat sputum cytology 3 to 5 times. Conclusion: Bronchoscopic examination is important to determine the histologic cell types in lung cancer. In addition, we should be interrested in improving diagnostic yields of sputum cytology as an easy method.
