The purpose of this study is to examine the publication, composition, method of composition, and acceptance patterns of JujaDaejeon anthologies edited by Joseon scholars in the Joseon dynasty. When a large amount of JujaDaejeon was published in the 16^th century, anthologies of JujajaDaejeon was compiled, published and learned as a way to understand it. A total of 13 kinds of JujajaDaejeon anthologies were published, including six kinds in the early Joseon period and seven kinds in the late Joseon period. And the composition of main anthologies showed a trend that was supplemented by Jeong Gyeong-se's Jumunjakhae from Lee Hwang's Jujaseojeolyo, and aggregated into Song Si-yeol's Jeoljaktongpyeon(boyu). JujaDaejeon consists of total 3,645 works except for poems. Among them, 1,734 works were selected by 13 anthologies. The theme of a work with a high cumulative number of selections is the virtue and attitude of the king, policy proposals, the appointment of talent, the duty of subjects, criteria for evaluating historical figures, opposition to harmony with Jin and territorial restoration, and academic discussions. This study is expected to be meaningful in the field of the research on the acceptance of the foreign books and acceptance of the Zhu Xi's works in the Joseon dynasty.

The effective elastic constants of a single-crystal superlattice film have been determined by two methods based on the velocities of surface acoustic waves (SAW). One method uses formulas to calculate the effective elastic constants of a superlattice from the known elastic constants of the constituent layers. The calculated effective elastic constants are tested by comparing the corresponding SAW velocities calculated for thin-film/substrate systems with the corresponding SAW velocities measured by line-focus acoustic microscopy (LFAM). The other method determines the effective elastic constants of the superlattices by inverting the SAW velocity dispersion data measured by LFAM. The results of both methods applied to a TiN/NbN superlattice film are in good agreement.

This paper aims to analyze and introduce the primary English curriculum of North Korea reformulated according to the New Educational Program. Sources for analysis are the 4th and 5th primary school English syllabus based on the New Educational Program, explanations of the New Educational Program appeared in People's Education and Kim, Jeong-Il's selected writings. The analytical sources are classified into characteristics, objectives, contents, methods and evaluation. The findings are as follows: The primary English education aims to reach to the basis of middle school English by learning English alphabets and basic English expressions. 4th graders learn basic oral English such as pronunciation, stress and intonation for the first semester and learn English alphabets and their sounds for the second semester. 5th graders learn familiar topics in English and repeatedly practice the important components of English such as pronunciation, vocabulary and grammar. The method is to maintain students' interests in English and encourage students to use classroom English. Also, structural practice is an important part of the method. Evaluation is primarily process-oriented and must motivate students to excel in English rather than fail in English.
