플립드 러닝을 적용한 한국어 수업이 학업 성취도에 미치는 효과
김아름 ( Kim¸ Arum ) 국제한국어교육학회 2020 한국어 교육 Vol.31 No.3
The purpose of this study was to investigate the effect of the flipped learning method implemented in a Korean as a Foreign Language (KFL) classroom at the tertiary level. The treatment variable of the experiment was a teaching method: a flipped learning for the experimental group and a traditional class for the control group. A total of 72 university students participated in this study and the research was conducted for 14 weeks. The results were as follows. First, the overall academic performance of the experimental group was higher than that of the control group, but these differences between groups were not statistically significant. Second, the listening and speaking academic performance of the experimental group was higher than that of the control group, and these differences between groups were statistically significant. This study shows that implementation of flipped learning brings an increase in academic performance, especially communicative listening and speaking skills compared to lecturer centered classes. Flipped learning lessons give more time for interaction between teachers and students than lecture centered classes. This result indicates that using flipped learning provides time for various inquiry activities and task solutions and therefore, enables positive effects on learning achievement.

The scalar intensifier ku in Korean : The case of KUintensifier with anti-specific wh-indeterminates

Arum Kang. 2018. The scalar intensifier ku in Korean : The case of KUintensifier with anti-specific wh-indeterminates, Language and Information, 22-1, 73-89. The purpose of this paper is to present the account of the novel function of ku in Korean. I will focus on the emphatic variant of ku co-occurring with anti-specific wh-indeterminates (i.e., Free Choice Items, Negative Polarity Items, Referential Vagueness Items), which has generally received less attention than the definite one. I suggest that the meaning of ku in this case is not associated with the core property of definiteness. Instead, given the set of empirical data, my proposal is that (i) the hallmark properties of emphatic ku are suggested as a) scalarity, b) additivity, c) weak polarity, and (ii) the pragmatic contribution of the emphatic ku can be characterized in terms of scalar intensifier. The scalar intensifier ku contributes the presupposition that there is a set of alternatives of anti-specific wh-indeterminates which is base-α, and that these alternatives are ranked on a scale. Its scalar presupposition denotes the least likely values on the likelihood scale. The implication of my finding leads to the fact that Korean is a language which reveals a dichotomy in encoding distinct type of weak familiarity (i.e., the scalar intensifier ku) and strong familiarity (i.e., the definite ku).
Microsystems for Whole Blood Purification and Electrophysiological Analysis

This paper presents the development of a microsystem for whole blood purification and electrophysiological analysis of the purified cells. Magnetophoresis using continuous diamagnetic capture (DMC) was utilized for whole cell purification and electrical impedance spectroscopy (EIS) was utilized for electrophysiological analysis of the purified cells. The system was developed on silicon and plastic substrates utilizing conventional microfabrication technologies and plastic microfabrication technologies. Using the magnetophoretic microseparator, white blood cells were purified from a sample of whole blood. The experimental results of the DMC microseparator show that 89.7% of the red blood cells (RBCs) and 72.7% of the white blood cells (WBCs) could be continuously separated out from a whole blood using an external magnetic flux of 0.2 T. EIS was used as a downstream whole cell analysis tool to study the electrophysiological characteristics of purified cells. In this work, primary cultured bovine chromaffin cells and human red blood cells were characterized using EIS. Further analysis capabilities of the EIS were demonstrated by successfully obtaining unique impedance signatures for chromaffin cells based on the whole cell ion channel activity.

In this paper, I establish a new type of modal disjunction system in Korean. Thus far, (i)na has been considered as a typical modal disjunctive particle. Introducing inka as a new type of modal disjunctive particle, I propose that the class of Koran modal disjunctive particles is not homogeneous, and there should be fi ne-grained distinction system. Considering that (lack of) epistemic knowledge of the speaker is one of the possible dimensions of variation within the class of modal disjunction, my proposal on the use of inka is identified as an irrealis marker (Mauri 2008) which specifies alternative disjuncts with irrealis value. I further show that the epistemic constraint of inka on the irrealis value is characterized as a condition of minimal variation and uncertainty of anti-specific disjunction in the sense of Giannakidou and Quer (2013).
Product-Service System(PSS) 성공, 실패요인에 관한 탐색적연구: Case Study

많은 기업들은 지속적인 경쟁력을 확보하기 위해 기업의 역량과 제품의 성능에 중점을 두는 기존방식보다 고객의 요구에 중점을 두고 고객의 입장에서 제품을 만들고 있다. 이러한 과정에서 나타난 PSS(Product Service System) 시스템은 제품과 서비스가 하나로 통합되어 고객에게 차별화된 가치를 제공하고, 기업이 경쟁력을 가지고 지속적인 성장을 할 수 있게 지원하고 있다. 본 논문에서는 이러한 PSS 플랫폼 비즈니스 모델로 성공한 Amazon 의 Kindle 과 Apple 의 ipod, 실패한 Microsoft 의 June 과 Sony 의 e-book reader 를 채택하여 사례연구 방법론을 통해 성공요인과 실패요인을 도출하고자 한다. 이를 위하여, 사례분석을 통해 가설을 도출하고, PSS 에 관한 문헌연구와의 비교 및 분석을 통하여 PSS 시스템에서 상업적으로 성공하기 위한 전략적 시사점을 제시하였다.
Development of an Online Practicum Program in Critical Care Nursing for Undergraduate Students
Arum Lim,Jung-Yeon Kim,Phill-Ja Kim,Yeonsoo Jang 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10
Aims: The clinical practicum is crucial in facilitating the transition from academic to professional setting. However, the coronavirus disease 2019 pandemic has created many challenges in clinical placement for undergraduate students, especially regarding critical care nursing. This study aimed to develop an online practicum program to supplement the critical care nursing clinical practicum for undergraduate students. Methods: This methodological study utilized the Analysis, Design, Development, Implementation, and Evaluation model. Content validity was measured by 13 critical care nursing experts. In addition, to establish clinical validity, SERVQUAL was used to measure satisfaction with the online practicum program among 30 undergraduate students. The online program was applied in the fall and spring semesters of 2020 and 2021, respectively, at a nursing college in Korea. Results: We developed the online practicum program based on a literature review and the nursing college’s learning outcomes. Seven video clips, three case studies, and two scenarios of computer-based communication simulation were developed through cooperation among the investigators and clinical nursing professionals. The item-level content validity index scores were >0.91, acceptable to verify this program. The mean scores for perceptions regarding the online practicum program were significantly higher than those for expectations (mean difference 0.53, p<.001). The mean difference was most increased in the order of assurance and responsiveness. Conclusion: Online practicum programs could supplement clinical practicums for undergraduate nursing students in case clinical placement in intensive care units is challenging. Further research should be conducted to evaluate the learning effectiveness of hybrid online programs in critical care nursing practicums for undergraduate students.
