This study regards that a cause of intensifying sovereignty disputes between Korea and Japan over the Dokdo island has resulted from the fallacy of Dokdo's development policy directly related to exertion and consolidation of Korean government's sovereignty on Dokdo, which has been under Korea's effective control since 1953. From this internal view, this study critically reviews the Korean government's development policy for Dokdo from the 1950s to the end of July 2012 and suggests an ideal alternative for future development of Dokdo on the basis of the discussion of the problems of Dokdo's development policy and its different future development directions proposed in Korean society. The Korean government implemented quite passively the development policy for the inhabited island which is required for the consolidation of sovereignty over Dokdo not to hinder the friendly diplomatic relationship between Korea and Japan. Dokdo is currently not acknowledged as the Korea's Dokdo island in international society, but mostly called Liancourt Rocks. It may be due to the fact that Korea did not positively develop Dokdo as a valuable island which a number of Koreans can inhabit. Consequently this paper proposes 'Dokdo eco-village' as an alternative development plan from the perspective of sustainable development which the UN has adopted. It is a small scale village that contains economic function of eco-friendly fishing, eco-tourism and East Sea research. The hope is that Dokdo eco-village draft plan will be a clue to the discussion and establishment of new Dokdo's development policy to strengthen the Korea's sovereignty and effective control over Dokdo in the future.

This study aimed to identify the efficiency of online non-face-to-face English classes to propose possibilities for expanding these types of classes in a sustainable way even in the post-COVID era. Moreover, the study suggests pedagogical implications for the directions that should be further explored for online non-face-to-face English classes. To this end, the study employed an online non-face-to-face English reading class using Zoom and investigated the effects of online teaching on college students' reading comprehension via two achievement tests. The study also analyzed learners' satisfaction or dissatisfaction with this online non-face-to-face English reading class (and their reasons) through a questionnaire. Ultimately, the study found that online non-face-to-face English reading classes have a positive effect on learners' reading comprehension learning. In addition, the reasons for learners' satisfaction with online non-face-to-face classes include systematic class progress, class quality, and efficiency of learning. Instructors must be aware of the need to expand online non-face-to-face classes, for which they will have to be thoroughly prepared in advance. Instructors will also need to implement efficient online class activities, organize classes systematically with detailed explanations, and provide quick and useful feedback.

Matrix theory is widely used not only in mathematics, natural sciences, and engineering, but also in social sciences and artificial intelligence. In the 2009 revised mathematics curriculum, matrices were removed from high school math education to reduce the burden on students, but in anticipation of the age of artificial intelligence, they will be reintegrated into the 2022 revised education curriculum. Therefore, there is a need to analyze the matrix content covered in other countries to suggest a meaningful direction for matrix education and to derive implications for textbook composition. In this study, we analyzed the German mathematics curriculum and standard education curriculum, as well as the matrix units in the German Hesse state mathematics curriculum and textbook, and identified the characteristics of their content elements and development methods. As a result of our analysis, it was found that the German textbooks cover matrices in three categories: matrices for solving linear equations, matrices for explaining linear transformations, and matrices for explaining transition processes. It was also found that the emphasis was on mathematical reasoning and modeling when learning matrices. Based on these findings, we suggest that if matrices are to be reintegrated into school mathematics, the curriculum should focus on deep conceptual understanding, mathematical reasoning, and mathematical modeling in textbook composition.

본인등이 Agirtrodon halys blomohoffi 및 Trime-resurus flavoviridis 독에 대한 inhibitor를 미생물계에서 분리코져 시도한 것은 1966년경 부터였으며 그 후 1971년에 inhibitor 2종을 분리하게 되었으며 이 2종의 inhibitor는 그 작용상이 대단히 유사하나 금속에 대한 성질, 그 정제성등에 다소 차이를 나타내었다. 금반에는 이 2종 inhibitor의 작용조건 및 그 작용상에 대해서 발표코저 한다.

코브라과 (Elapidae)에 속하는 뱀에는 극소량으로도 치사시킬수 있는 독을 가지고 있는데 독을 구성하고 있는 물질중 특정한 계열의 단백질이 매우 두드러진 약리학적 활성을 보여줄수 있다. 따라서 본 연구는 독사들의 혈액독소 및 신경독소를 우리나라에서 제일 종류가 많은 위암세포주(SNU-1)에 대해서 세포독성을 검색하고 곤충 및 해양생물의 독소에 대해서도 위암세포주를 이용하여 검색하였다. 검색 결과 king cobra계통인 Ophiophagus hannah의 분획은 SDS-PAGE에서 분자량이 66,000 부근에 나타난 것이 세포독성물질로 추측되며 더욱 정제하여 아미노산 서열을 비교하고 Phospholipase화성을 측정함으로써 세포독성물질의 규명이 가능하리라 생각된다.

이 글은 영국, 독일 및 프랑스의 간호원제도에 관하여 종래 조사된 것을 정리 취합한 것이다. 각 국의 간호원제도를 기술함에 있어서는 주로 법제, 간호원의 종류와 수, 자격요건, 양성제도, 근로조건, 근로사정의 항목으로 나누고 다시 그 주 항목을 적절히 세 항목으로 분할하였다. 국가별 항목별에 있어서 그 설명에 약간의 차이가 생긴 것은 각 국에 대한 자료수집상의 제약 때문이며 부득이한 일이었다.
