About the Lab
Professor Sookyung Park's research lab focuses on applied linguistics and writing studies, with a strong emphasis on second language (L2) writing performance, particularly among Korean EFL university students. The lab investigates how discourse modes—such as narrative and argumentative writing—affect linguistic features like fluency, syntactic complexity, lexical diversity, and accuracy. It also explores the impact of writing proficiency, rater perspectives (including native and non-native English-speaking teachers), and assessment methods (holistic vs. analytic rubrics) on writing outcomes. Additionally, the lab examines psychosocial factors in clinical populations, such as symptom clusters and quality of life in patients with atrial fibrillation, reflecting a multidisciplinary approach to health-related quality of life and patient-reported outcomes.

15Background: Patients with atrial fibrillation (AF) experience diverse symptoms such as palpitations, dizziness, and fainting that lead to depression, anxiety, and poor quality of life. Management of symptoms is fundamental for AF, and with the increasing prevalence of AF, studies on management of symptoms in patients with AF are needed. Objectives: This study aimed to assess symptom clusters according to symptom severity in patients with atrial fibrillation and evaluate the relationships between
This article proposes that the Republic of Indians can be taken as a socio-political unit for analysis of the colonial regime of New Spain. After the military victory in Tenochtitlan, the encomienda and the municipality were implanted in New Spain as the first colonial systems. However, the power struggles carried out between the conquistadors, the Spanish Crown, the royal authorities, the settlers, and the clergy resulted in the modification of the colonial system. The Republic of Indians appea
This study investigated whether two different writing tasks (narrative and argumentative), elicit different lexical features. This study also attempted to identify the relationship between lexical features and the level of writing proficiency. Seventyeight university students wrote one narrative and one argumentative essay, with a 30-minute time limit for each task. A total of 156 essays were rated by eight raters using holistic rubrics, and then were divided into three levels of writing profici
This study examines how native English speaking (NES) and Korean non-native English speaking (KNES) teachers assess L2 writing performance. More specifically, this study aims to investigate whether these two groups of raters evaluate writing samples differently when using different rating scales (holistic vs. analytic) and different task types (narrative vs. argumentative). Four NES and four KNES raters evaluated 78 narrative and 78 argumentative essays written by Korean EFL university students
The purposes of this study were to examine (1) the effect of two different modes of discourse,i.e., narrative and argument, on the level of writing performance, fluency, and syntactic complexity of compositions written by Korean EFL university students; (2) whether the level of writing proficiency affects fluency and syntactic complexity of compositions written in each mode. The writing samples were collected from seventy-eight Korean university students, rated using a holistic rubric, and then

The conservation status of an endemic perennial herb, Hanabusaya asiatica (Nakai) Nakai (Campanulaceae) was determined by applying the IUCN risk assessment criteria from our field study and available specimen data.Also, the GIS technology was used to develop a species distribution map to calculate the extent of occurrence (EOO) and area of occupancy (AOO) for the taxon.After two years of continuous field studies, 269 mature individuals were found in four localities in 2011, while 216 mature indi
Subalpine species, Sorbus pohuashanensis in the Korean peninsula, which is assumed to be evolved from hybridization between S. commixta and an unknown species based on the flavonoids data.Morphometric analysis was conducted on the basis of 19 leaf and flower (or fruit) characters.A total of 721 samples in 13 populations of Sorbus pohuashanensis and S. commixta from Korea and additional specimens of S. commixta, S. pohuashanensis, and S. wilsoniana from Japan and China were examined to reveal the
15세기 중반 쿠스코를 기반으로 성장한 잉카인들이 주변 지역을 군사적으로 정복하면서 타완틴수유가 성립되었다. “4개 지역”을 의미하는 타완틴수유는 흔히 잉카제국으로 불리며, 1530년경에는 남북으로 4000km에 이르는 영토와 천만 명에 이르는 주민을 통치하기에 이르렀다. 타완틴수유로 복속된 지역들은 잉카인에게 정복당한 후에도 지역의 정치경제 구조를 유지했으며 중앙으로서 쿠스코는 지역적 독자성과 공존하는 집권화를 유지시켰다. 안데스 사회의 호수성은 재분배와 함께 타완틴수유의 기본 원리로 작용했다. 본 논문은 칼 폴라니와 존 무라의 논의에 기대어 호수성과 재분배를 중심으로 스페인 접촉 이전 타완틴수유의 정치경제구조를 분석한다.
Abstract We examine how the Fed's preference influences the behavior of inflation rate and unemployment rate using US data over the period of 1960–2017. After showing instability in a constant‐coefficient regression, we run a nonparametric regression, and find that the Fed's preference parameters have moved, implying that its preference can be represented by the asymmetric preference model putting more weights on high unemployment rate approximately before the era of Volcker's chairmanship and b
