A Soicolinguistic Study on Language-Mixing : In Case of Korean-American Advertising
Changyong Yang 한국언어연구학회 2015 언어학연구 Vol.20 No.1
Yang, Changyong. 2015. A Sociolinguistic Study on Language-Mixing: In Case of Korean-Merican Advertising. Journal of Linguistic Studies 20(1), 133-149. The main purpose of the present paper is to investigate the socio-cultural language factors which function as main elements that determine language-mixing in a Korean newspaper circulated in the KAC. The data for this study were drawn from a newspaper which is circulated among bilingual communities in the US in which Korean is widely used and English is also dominant. It is natural that under such conditions the English-mixed rate in advertisements in the newspaper be high, even though the amount of English in advertising varies with social factors. Therefore, an attempt has been made to see to what extent English is used in a bilingual community of an English-based country in terms of sociolinguistic factors. In doing so, it is expected that this study will serve a complementary function to previous studies. (Jeju National University)

This study examines the background and characteristics of the development of K-POP dance, a cultural asset of Korea, and suggests definitions and concepts for terms that are currently used interchangeably. In addition, based on this, this study was proposed to focus on educational value. Above all, as the background of the development of K-pop dance changed to visual music over time, the role of dance became very important, and the process of acceptance and change through overseas dance materials could be found. Three characteristics of K-POP dance were derived as follows. First, it had a ‘compositional feature’ to maximize the visual image as a constituent feature of the dance. Second, it has a “reflection characteristics”, the code of public arts in Korea, which is reflected in the dance are represented. Third, with the advent of YouTube, access to K-POP dance has become more convenient and has the characteristics of ‘spreading through voluntary participation’. In this way, based on the development background and characteristics of KPOP dance, it was judged that it would be appropriate to use the term ‘K-POP dance’ as an independent dance genre. In addition, based on the previous research, K-POP dance was confirmed to have value as cultural art education, value as communication and healing, and educational value as a part of lifelong education. Therefore as an educational program that all generations can enjoy and learn, it was able to prove as a ‘total package dance performance’.
A Discourse Marker keymey in the Language of Jeju : Its pragmatically-controlled functions and use
Changyong Yang 한국언어연구학회 2016 언어학연구 Vol.21 No.1
Little research has been done on linguistic analysis on Jejueo in general and discourse approach to various Jejueo expressions in particular. This is because Jejueo has been treated, at best, as a dialect of Korean. However, it has been noticed that the language used in Jeju is “not mutually intelligible with Standard Korean”(Cho, et al 2001, Yang 2014 et al). As an independent language, Jejueo has its own linguistic features. With this in mind, the current study is to explore the pragmatic nature of keymey in Jejueo, the language of Jeju, from a discourse-functional point of view. As an interactional communicative tool, the discourse marker serves various discourse functions such as softener, agreement, attention-calling, etc. Furthermore, this study is to classify these functions into two properties: basic property and derived property. The former has something to do with ‘polite interaction’ and the latter includes various discourse functions. In this way, it is expected that the present study manages to provide, though descriptive, discourse-functional approaches to various oral features of Jejueo.
Optical spectroscopy of Tb³+ ions doped NaCa(PO₃)₃ phosphors
Changyong Yoon() 한국방사선학회 2018 한국방사선학회 논문지 Vol.12 No.4
Luminescence properties of NaCa(PO₃)₃ doped with Tb³+ ions are investigated by optical and laser excitation spectroscopy. The phosphors were prepared by solidstate reaction method The X-ray diffraction(XRD) was used to analyze the crystal structure and the crystallinity of the samples. The excitation and emission spectra and decay curve of NaCa(PO₃)₃ : Tb³+ (0.01~30mol%) were measured at room temperature. The f-d band of Tb³+ is observed in the excitation spectra of NaCa(PO₃)₃:Tb³ in the wave length region 205~245nm. Strong emission lines due to the 5 D₄→ 7 F J transition and weak emission lines due to the 5 D₄→ 7 F J transition are observed in the emission spectra of NaCa(PO₃)₃: Tb³+. The energy transfer and cross relaxation between Tb³+ ions are discussed in NaCa(PO₃)₃: Tb³+ in the emission spectra and life time. Tb 3+ 이온이 첨가된 NaCa(PO₃)₃ 형광체의 여기 및 방출 스펙트럼 및 레이저 분광 측정을 통하여 형광특성을 조사 하였다. 고상법으로 NaCa(PO₃)₃:Tb³+ 형광체를 합성하였다. X선 회절측정(XRD)을 사용하여 형광체의 결정 구조 및 결정성을 분석하여 Tb³+ 이온이 30 mol%까지 첨가되어도 형광체의 결정구조가 NaCa(PO₃)₃의 결정상을 유지하였다. NaCa(PO₃)₃: Tb³+ (0.01-30mol %)형광체의 여기 및 방출 스펙트럼과 형광의 감쇠곡선을 상온에서 측정 하였다. NaCa(PO₃)₃ :Tb³+ 의 여기 스펙트럼에서 205~245 nm 영역에서 넓은 Tb³+ 의 4f-5d 전이에 의한 f-d 밴드가 나타났다. NaCa(PO₃)₃ :Tb³+ 의 방출 스펙트럼에서 5D₄→ 7 F J 전이에 의한 강한 피크와 5 D₃→ 7 F J 전이에 약한 피크가 관찰 되었다. 방출 스펙트럼의 형광 강도와 형광의 수명시간 분석을 통하여 Tb³+ 이온 사이의 에너지 전이 및 교차 이완이 확인되었다.
