In this paper, we examine how secondary school mathematics textbooks on calculus introduce the history of calculus. In order to identify the problem, we consider the Babylonian integration by trapezoidal rule, which was made to calculate the location of Jupiter in 350-50 B.C., and the integration by the method of the rotating plate of ibn al-Haytham in Egypt, about 1000 years. In conclusion, our secondary school mathematics textbooks describe Newton and Leibniz as inventing calculus and place their roots in ancient Greece. The origin of the calculus is in Babylonia and the Faṭimah Dynasty (909-1171) (Egypt) and it is desirable that the calculus is developed in Europe after the development of the power series in India, and that the value of Asia Africa is introduced in the textbooks.

Among various region detector and shape feature extraction method, MSER(Maximally Stable Extremal Region) and SIFT and its variant methods are popularly used in computer vision application. However, since SIFT is sensitive to the illumination change and MSER is sensitive to the scale change, it is not easy to apply the image similarity retrieval. In this paper, we present a Scale and Rotation Invariant Region Feature(SRIRF) descriptor using scale pyramid, MSER and affine normalization. The proposed SRIRF method is robust to scale, rotation, illumination change of image since it uses the affine normalization and the scale pyramid. We have tested the SRIRF method on various images. Experimental results demonstrate that the retrieval performance of the SRIRF method is about 20%, 38%, 11%, 24% better than those of traditional SIFT, PCA-SIFT, CE-SIFT and SURF, respectively.

Building on the framework of language socialization [10] in language learning and use, the present study examines the environmental factors involved in four college students' English learning in the situated place of the home during the COVID-19 pandemic. Using narrative inquiry, this study implements a time-series analysis to investigate undergraduates' online English learning in a rural area of northwest China. The data were collected via oral and written narration, semi-structured interviews, and class documents. Leveraging the field-habitus theories, the findings reveal that each of the students had a different habitus in the family field that influenced their English learning at home between March to July of 2020. Ultimately, all four students felt that their habitus made their online English learning ineffective and expressed that they did not wish to continue learning at home. The findings imply that it is important for rural parents to pay more attention to building college students' learning environments and helping students cultivate a strong learning habitus in the family field in northwest China.

Purpose: The purpose of this study was to identify how nursing students' awareness of biomedical ethics and ethical values affect their attitudes towards a do-not-resuscitate (DNR) order. Methods: This cross-sectional correlation study was conducted with 275 nursing students enrolled at two universities in North Chungcheong Province and North Gyeongsang Province of South Korea. Data were collected in April 2017 using a self-reported questionnaire. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression with the SPSS/WIN 23.0 program. Results: The students' attitudes towards DNR were positively correlated with attitudes that seek ethical values but negatively correlated with their biomedical ethics awareness. The explained variance for attitudes towards DNR was 20%, which was significant (F=13.01, P<0.001). Conclusion: These findings suggest that nursing students' biomedical ethics awareness and ethical values were associated with their attitudes towards DNR. Curriculum organization and various educational programs should be developed and applied to help nursing students develop ethical values and awareness of biomedical ethics.

This paper aims to examine the base inflectional forms of Korean old vernacular letters, and explain why it appears with frequency. In the korean old vernacular letters, the suffix 'ha-' and ending of the 'Base+ha-' adjective derivation are not appear with extraordinary frequency. I called it the base inflectional forms. I consider it in function and morphological constructions and also the syntactic constructions. Whenever Joseon-era people wrote a letter with a time limit, they have need to diminish their exertion to use of the brush. Therefore the base inflectional forms appear with extraordinary frequency in comparison with other papers. In the 'X ha-' word formation of Korean old vernacular letters, 'ha-' is formal morpheme without substantial meaning. So 'X' is left and 'ha-' and ending can be omitted resolutely. The base inflectional forms are occurred to voluntary language performance for a particular intention. but it is not appear in all conditions. In some circumstances, it appear. I checked out the constructions on base inflectional forms. In the 'X ha-' word formation, 'X' is predicative base without fail. and the ending which take part in base inflectional forms has a grammatical function unadulteratedly.

The present paper considers lice described in some premodern Korean proses, focused on the implications of lice and the literary strategies adopted by the writers in dealing with this unique subject matter. The works reviewed in this process are "A Story of the Louse and the Dog" by Lee Gyu-bo (Goryeo Dynasty), "The Old Man's Vindication of Lice" by Gwak Yeol (Early Joseon), "A Small Realization" by Yu Sin-hwan (Late Joseon) and "Miscellany" by Heo Jeon (Late Joseon). In these premodern essays, an allegory of lice was used to disclose various kinds of prejudices that people generally had: against things small (in "A Story of the Louse and the Dog"), against the old (in "The Old Man's Vindication of Lice"), against the dichotomous idea of right and wrong (in "A Small Realization") and against various aspects of life (in "Miscellany").

Even though "An Outpost of Progress" and Heart of Darkness were based upon Joseph Conrad the sailor's same experience in Congo Free State, their narrative strategies are quite different. The realistic representation of "An Outpost of Progress," with which Conrad was not satisfied at all, was converted into the modernistic narrative strategy of Heart of Darkness so that the sympathetic power of the story should be improved. The conservative value system of realism is expressed by the omniscient author in "An Outpost of Progress," whereas the frame narrator of Heart of Darkness is proved to be an unreliable one whose norms and behavior are not in accordance with the implied author. The glorious history of the British Empire, which was proudly presented by the frame narrator at the beginning of Heart of Darkness, was strongly opposed by Marlow, another narrator, who said that the British Empire had been "one of the dark places of the earth" when ruled by the Roman Empire. The feeling of the frame narrator was uneasily changed into the gloomy mood when he described the Thames as the flow which "seemed to lead into the heart of an immense darkness" at the end of Heart of Darkness. Similar to the straightforward narrative strategy of representation in "An Outpost of Progress," the realistic approach of Part I in Heart of Darkness is considered by Conrad as insufficient to reveal the darkest truth of imperialism, which was declared by Kurtz as "The Horror! The Horror!" Thus Conrad uses the Chinese-box structure, in which Kurtz' episode is enveloped by Marlow's tale which is enclosed by the frame narrator's story, in order to penetrate into the mind of ordinary readers in the novelist's age of New Colonialism, while attacking the ideology itself of imperialism instead of critisizing its inefficiency and individualism.

This study was to identify the factors influencing the interpersonal competence in nursing students. Data collection was conducted on 167 university students from November to December 2019. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical multiple regression using the JAMOVI program. As a result of the study, the interpersonal competence of the subjects was different according to gender, personality, life satisfaction and weight satisfaction, and there was a positive correlation between psychological well-being and self-esteem. Factors affecting interpersonal competence include positive personality groups (β=.31, p=.027), psychological well-being (β=.21, p=.022) and self-esteem (β=.24,) p=.007), and these variables accounted for 25.2% of interpersonal competence. Therefore, in order to improve the interpersonal competence of university students, it is necessary to develop a program that considers their psychological well-being and self-esteem.
