The physiological functions of the ovary and development of the corpus luteum occur through the activation of endocrine hormones. In this process, estrogen, a reproductive hormone, is secreted in the ovarian follicle and corpus luteum and affects corpus luteum formation and regression. Estrogen controls the synthesis of reproductive hormones by binding to estrogen receptor–α and –β. Estradiol–17β, synthesized in the ovary, regulates the physiological function of the corpus luteum and the angiogenesis signaling pathway. Estrogen controls progesterone synthesis, which is regulated by StAR-transported cholesterol, P450scc-converted pregnenolone in mitochondria, and 3β-HSD-synthesized progesterone in the smooth endoplasmic reticulum. Estrogen secretion is also stimulated by kisspeptin and regulated by gonadotropin-releasing hormone, follicle-stimulating hormone, and luteinizing hormone. Moreover, the formation of the corpus luteum is closely regulated by angiogenesis. VEGF is an important factor in angiogenesis and plays a role in the survival, proliferation, and migration of endothelial cells. Especially, VEGF–A is a key factor in the physiological functions of endothelial cells. VEGF binds VEGFR–2 and affects the signaling pathways of PI3K, Akt, MAPK, and ERK. Also, VEGF binds to HIF–1α, inducing VEGF secretion. Estrogen promotes the activation of HIF–1α, while the activation of mTOR and Akt stimulates VEGF secretion. Therefore, estrogen is a major reproductive hormone in physiological function and the synthesis and secretion of endocrine hormones in the ovary and corpus luteum.

This paper explores the standards for selecting language materials during the study of the diachronic grammar of Classical Chinese. The accuracy of language materials is crucial for ensuring the scientific validity of research conclusions. Due to previous limitations in research on the language materials of the Spring and Autumn period, such as posteriority and singularity, this paper argues that the increasing availability of excavated documents, especially ancient literary texts, provides a reliable research foundation for describing the grammar of Classical Chinese during this period. Therefore, this paper attempts to answer the following questions: 1) Which language materials should be used for the study of the grammar of Classical Chinese during the Spring and Autumn period? 2) Why should these language materials be selected? 3) What are the standards for selecting language materials during this period? The purpose of this study is to provide a reference for the diachronic study of Classical Chinese grammar.

Cho, Eun & Oh, Sun-Young. (2023). “Representation of Native English Teachers and Korean English Teachers in Korean English Newspapers: A Corpus-based Critical Discourse Analysis”. The Sociolinguistic Journal of Korea, 31(2). 95-123. Native-speakerism, a pervasive issue in the field of English Language Teaching, is observed globally and prevalent in Korea. This ideology negatively affects both Native English Teachers (NETs) and Non-native English teachers like Korean English Teachers (KETs) for some reasons. This study utilizes corpus-based critical discourse analysis to examine the linguistic patterns and referential expressions used in Korean English newspapers to represent NETs and KETs. The analysis reveals significant disparities in their positions and authority within Korean English classrooms. Specifically, NETs are labeled as “assistants,” implying a subordinate role with limited authority, while KETs are referred to as “co-teachers,” signifying a more secure status. Moreover, the study highlights the challenges faced by KETs in demonstrating their English proficiency and sheds light on the discrimination faced by NETs who possess commodified linguistic capital and are of Caucasian descent. These findings emphasize the importance of raising awareness of native-speakerism in Korean newspapers.

In recent years, an array of studies has focused on ‘translationese’ (i.e., unique features that manifest in translated texts, causing second language (L2) writings to be similar to translated texts but different from native language (L1) writings). This intriguing linguistic pattern has motivated scholars to investigate potential markers for predicting the divergence of L1 and L2 texts. This study builds on this work, evaluating the feature importance ranking of specific translationese markers, including standardized type-token ratio (STTR), mean sentence length, bottom-frequency words, connectives, and n-grams. A random forest model was used to compare these markers in L1 and L2 academic journal article abstracts, providing a robust quantitative analysis. We further examined the consistency of these markers across different academic disciplines. Our results indicate that bottom-frequency words are the most reliable markers across disciplines, whereas connectives show the least consistency. Interestingly, we identified three-word lexical bundles as discipline-specific markers. These findings present several implications and open new avenues for future research into translationese in L2 writing.

The study aims to investigate Korean English learners' usage of pragmatic discourse markers in their impromptu speech. Korean English Learners' Spoken Corpus, abbreviated as KELSC, is the main data source for analysis(Jung, 2021). To analyze the features of pragmatic discourse markers in KELSC, three focal pragmatic discourse markers(PDM) okay, like, and so are selected and analyzed by using WordSmith 7.0(Scott, M. 2016) and Lancsbox 6.0(Brezina et al., 2021). The findings indicate that three focal PDMs okay, like, so are not appearing more frequently in the higher levels of learners, unlike previous studies. Instead, the intermediate levels of B1 and C1 used two focal PDMs, okay and like the most, respectively. However, the lowest A1 learners rarely used the focal PDMs in their speech. Two PDMs okay and so are used as a co-occurring pattern in level C while so and they have a shared collocate in level A.

Despite the massive impact of COVID-19 on society, beyond the numbers of confirmed cases and deaths, there remains a lack of large-scale data depicting the effects of the virus on the society of the Republic of Korea. To fill this gap, we collected 1.822 million news articles with more than 1 billion morphemes from January 2020 to June 2022, creating a Korean version of the Coronavirus Corpus. This corpus is introduced in the current study. In addition, to demonstrate how such massive corpus can be utilized, we conducted information theoretical analyses to see how the stance of the press media on topics such as vaccines and social distancing affected the COVID-19 situation in the Republic of Korea. Specifically, we utilized several computational linguistic skills including concordance building and sentiment analysis through both traditional and machine learning techniques and measured the transfer entropy to estimate the impact with information theory. The results suggest that the overall impact of the press media on the society was minimal to non-existent.

To clarify the concepts of dialects, vernacular and regional languages used with similar meanings, this study attempted to reveal the usage patterns and concepts of these expressions based on written corpus. The written corpus of printed newspaper articles from the online Naver News Library that archived newspaper articles from 1920 to 1999 and the news article corpus crawled by the online Naver News portal from January 1, 2004 to December 31, 2021 were extracted and analyzed. In particular, this paper analyzed the relationship between collates and keywords based on the corpus linguistic research methodology of the news article corpus for the past eighteen years and how they were being used in official records and press documents by corresponding with the 'dialects, vernacular, and regional languages' in socio-linguistic terms of modern Korean. The results are summarized as follows. First, the concept of linguistic norms that a dialects have terms corresponding to the words or standard languages was established after the 1930s. Second, in the library of newspaper articles published in the 20th century, dialects or vernaculars were perceived as negative objects to be removed in preparation for standard language. Third, it can be seen that the positive value judgment on 'vernacular' has increased in the corpus of news articles over the past decade. Fourth, dialects and vernacular, regional language, and standard language were used to be compatible with each other, and it can been seen that dialects were mainly used in academic contexts and vernacular were mainly used in everyday contexts. Fifth, it can be confirmed that the positive perception of standard language has been maintained in the 20th-century newspaper article corpus and the 21st-century news article corpus for the last eighteen years after the recognition of standard language.

This study employed a bibliometric method to visualize the evolution of corpus-based discourse studies between 1995 and 2019, with a total of 2,174 English-language documents and their 83,184 references collected from Scopus, the Social Science Citation Index, and the Arts & Humanities Citation Index. Co-citation analysis of the predominant authors, references, and publication sources disclosed that the field has expanded over the past 25 years from primary pattern analysis of descriptive and functional grammar to principal investigations of interdisciplinary issues, some of which are central to pragmatics and sociolinguistics. This shift of research focus is also evidenced by keyword analysis. Scholars have been progressively more fascinated by such social issues as news discourse, business discourse, gender and language, and identity. Some emerging topics like social media, media discourse, legal discourse, and the metadiscourse interpersonal model may represent research hotspots and trends in this area. Bibliometric approaches play an important role in providing hands-on evidence-based comparisons and visualizations of previous research outputs using different time bands.

By adopting a usage-based approach to language acquisition, this study investigated the emergence and development of L2 constructional knowledge. A total of 19 English verb-argument constructions (VACs) and their associated verbs were extracted from a learner corpus and three verbal fluency tasks, each conducted in L1 and L2 English and L1 Korean. We compared verb usage in the target VACs across proficiency levels between the L1 and L2 groups and between data types for VAC productivity and verb-VAC associations. The results identified three stages through which Korean learners’ VAC knowledge develops in L2 English: emerging through the frequent use of a few general verbs, expanding the range of verbs associated with a VAC to include more specific and prototypical verb types, and then developing them into a creative constructional schema. Moreover, we determined similarities between L1 and L2 English VAC knowledge in higher L2 proficiency levels, as well as L1 Korean influences related to L1 typology and L1 collocational transfer.

English globalization entails the use of English by speakers from mother tongues other than English. Trained and professional non-native speakers of English have reportedly achieved communicative competence owing to bilingual or multilingual experiences. Their pragmatic competence developed through diverse interactions with speakers from different cultural and linguistic backgrounds (Kecskes 2015). In this study, hedges were explored in international briefings where English was used as a lingua franca by professionals of an organization. Three hedging devices including modal verbs, modal adverbs, and pronouns were analyzed to investigate their pragmatic competence. In addition, the professional non-native English briefings were compared with the U.S. briefings for their similarities and differences. Results showed developmental patterns from learner English while they shared similarities with native data. These findings were accounted for by the varieties of English and the genre differences. Implications for pragmatic competence are discussed as well.

This study investigates the use of cohesive devices in the corpus of Korean college students’ compositions. In particular, it attempts to provide a comprehensive analysis of the lexico-grammatical contexts in which cohesive referential devices are employed in argumentative essays. For this purpose, a Korean EFL corpus and a native speaker corpus were analyzed based on Gray’s (2010) coding scheme. The coding scheme included variables such as the place and unit of the antecedent, the grammatical role and place of demonstratives, and their preceding or following structures. The results of the analysis showed that Korean EFL learners and native writers were similar in that they tended to use demonstrative pronouns as a subject and demonstrative determiners as objects/complements. Besides this general tendency, non-prototypical uses of the determiners were observed. The learners’ corpus manifested an overuse of an extended antecedent which could reduce the clarity of meaning. The most frequent verb following demonstrative pronouns was the copula (i.e., be) in both corpora. Finally, the learners tended to use a much smaller number of abstract/shell nouns than their native speaker counterparts.

Spontaneous motion is one of the most basic event types, but different languages use varying patterns to express it. For example, English usually encodes path information in prepositional phrases or adverbial particles, while Korean maps path information onto verbs (Talmy, 1985). This study predicts that this typological difference would affect English spontaneous motion expressions produced by Korean learners and analyzes two English-language speech corpora, one, the data from native speakers (600 recordings), and the other, data from L1-Korean learners of English (400 recordings). It finds that the learners significantly underuse satellite-framed patterns, but not verb-framed patterns, compared with the native speakers, suggesting that the L1 plays a role in their L2 production. The satellite-framed patterns, however, account for the greatest portion of spontaneous motion expressions in the L2 corpus, suggesting the dominant effect of input on L2 production. These findings lead to pedagogical implications concerning preventing L1 interference and fostering input-based L2 acquisition.

The purpose of this study is to examine a corpus regarding the use of discriminatory language and its perceptions. First, we examined informal job titles that indicate social views regarding the respective workers, and then we analyzed expressions indicating negative perceptions as well as negative expressions about occupations and tasks to determine negative views or attitudes toward the workers. Summarizing the results of the analysis, ganhowon(nurse) and cheongsobu(cleaner) as inappropriate titles, nogada(physical labor) and gongdori/gongsuni(factory boy/girl) as expressions of negative perception, and nogada and wunjeonsu(driver) in negative expressions related to occupations and work occur with high frequency. Ganhowon is used with titles for women like eonni(older sister), agassi(lady), and Miss ○, cheongsobu and pachulbu(day maids) with the titles ajumma(tannie) and ajeossi(older man), wunjeonsu and gongsuni with the epithets nom(jerk) and nyeon(bitch), and nogada with the titles ilggun(workers) and inbu(laborers), and such terms as jjapsae(the fuss) with a epithet saeggi(jerk/bleeder) are used mainly as inappropriate titles. Bad behavior, deprecatory social treatment, and negligent discrimination are conveyed in these expressions of negative perception. The expressions related to occupation and work were mainly used for professionals doing less respected or socially lower work or who do not work well, and there were many expressions indicative of low status or lower rank in the job hierarchy. Lastly, references to appearance and sexuality were those most frequently used in expressions conveying other occupational discrimination, and were found to be used mainly for ganhowon and gongsuni who are young women.

This study explored the effects of outlining on the summaries of thirty six L2 college students across three text genres and their opinions on the use of outlining in writing the summaries. Over the eight weeks, the students were divided into an outlining group (experimental group) and a keyword group (controlled group) wrote three summaries after reading articles across three genres (e.g. argumentative, expository, and narrative) at two weeks intervals. Additionally, a follow-up questionnaire on the use of outlining in writing summaries was conducted. Data were analyzed by the Syntactic Complexity Analyzer (Lu, 2010) under 14 indices, and the responses to the questionnaire were analyzed by percentages. The results found a statistically significant difference appearing only in the aspect of CT (i.e. clause per T-unit). In addition, a majority of students utilizing outlining for summary writing believed that they were helped not only to understand the contents and the structure of the articles, but to write summaries with their own words. These results have a pedagogical meaning in that outlining can be more efficient for specific reading genres when teaching summarization in L2 classes.
