The status of onglides in korean : evidence from speech errors

Kyung-Shim Kang 한국음운론학회 2003 음성·음운·형태론 연구 Vol.9 No.1

Kang, Kyung-Shim. 2003. The status of onglides in Korean: evidence from speech errors. Studies in Phonetics. Phonology and Morphology 9.1. 1-15. The issue of identifying the status of glides has long been controversial in Korean. The two competing theories, ie. Nucleus Hypothesis and Onset Hypothesis, consider the onglides as part of the nucleus and as the onset, respectively. Each theory, however, have often provided a contflicting account in reference to analogous evidence. Thus, I have collected 600 speech errors from spontaneous talks and readings on the radio, TV, and in conversation, and then analyzed them to examine the extent to which the glides participate and affect the other elements in making errors. By result, I found that, of the 76 slips relevant to onglides, the glides were associated with the following nuclear vowcl more often than the onset in errors. This suggests that the onglides in Korean be generated from the nucleus, and that they be optionally moved onto the onset during the speech production planning. In addition, the velar glide /w/ exhibited a distribution similar to /j/, but with an extremely low frequency (14% of the time), which implies that the feature [+round] assign it a marked status, hindering its substitution for other segments in errors.

A Case Study on the Educational Effectiveness of Online English Content Using the Storytelling Learning Method: Focusing on Students’ Perceptions and Opinions

Kang,Hye-Kyung(Hye-Kyung Kang) 영상영어교육학회 2024 영상영어교육 (STEM journal) Vol.25 No.1

This is a case study designed to determine the educational effect of online English content using the Storytelling Learning Method (SLM). The study focused on the course Learning English through Film offered by a cyber university in Seoul. A survey was conducted among 1,024 students from 86 universities who participated in the course. The course was based on the film A Dog’s Way Home (Smith, 2019) and followed the story of the film for 15 weeks over a semester. At the end of the semester, a survey was carried out to assess the following: 1) satisfaction with the online English learning content and improvement of English skills, 2) the effectiveness of SLM, and 3) students’ perceptions of their English skill improvement. The survey results revealed that 76% of the students found the SLM to be effective, and 92% expressed their interest and active participation in the course. In addition, 80% of the students reported that the online classes were more helpful in learning English, with listening and understanding context identified as the most improved language skills. These findings support the effectiveness of strategically structured course content utilizing SLM in terms of enhancing students’ motivation to learn and their academic achievements.

Laryngeal features for Korean obstruents revisited.

Kyung-Shim Kang 한국음운론학회 2004 음성·음운·형태론 연구 Vol.10 No.2

It is generally assumed that the three-way lexical distinction of Korean obstruents is characterized by two laryngeal features ? [spread glottis] and [constricted glottis]. Laxob struents have been regarded as unmarked with no laryngeal feature, where astense and aspirated counterparts have the marked features of [+constricted glottis]and [+spread glottis], respectively (Ahn 1983, Sohn 1987, and Kim 1987).However, Halle and Stevens (1971) and La defoged and Maddie son (1996) point out that the stiff vocal cords are attributed to a number of distinctive phonetic properties of Korean tense obstruents. Besides, Iverson (1983) demonstrates howt he stiff vocal cords is necessary for the characterization of Korean /s/. In line with those phonetic theories, a recent psycholinguistic study by Kang (2004) found that there exists asymmetry in manipulating laryngeal mechanisms with the highest variations for the lax, intermediate for the aspirated, and the least for the tense. The unproductive and restricted slips for the tense hints that a tense be involved with adifferent type of laryngeal setting other than the size of glottis. Kang’s slips data showing unusual interactions between /s/ and /ch/ also corroborate the claim by Iverson (1983) and Kang (2000) that Korean /s/ is a lax but aspirated. Moreover, the active interactions between a tense and aspirated obstruent also imply that the fortis be grouped together with the shared feature [+stiff vocal cords]. Therefore, based on prior phonetic accounts and psycholinguistic evidence, I suggest that[stiff vocal cord] needs to be defined in the representation of Korean obstruents for the optimal characterization of the tense in particular and laxness in general.

레이저 가공에서 빔변수가 미치는 영향에 관한 연구

강경구,방세윤,윤경구,황경현,이성국 동국대학교 산업기술연구원 1997 산업기술논문집 Vol.9 No.-

레이저 가공시 조사되는 레이저 빔의 특성을 나타내는 변수 - 예를 들면, 빔의 형상, 초점면과 소재사이의 거리, 빔 강도 분포, 빔의 발산각, 실제 빔이 퍼져가는 양상이 이상적인 Gaussian 빔에 비해 얼마나 큰지를 나타내는 beam quality factor 등 - 이 가공결과에 큰 영향을 미치는 것은 경험적으로 잘 알려져 있다. 특히 원적외선 레이저로 천공, 에칭 또는 엑사이머 레이저로 ablation 가공을 수행할 때는 이러한 빔특성 변수의 영향이 극대화된다. 본 연구에서는 중요한 빔특성 변수의 영향을 가능한 독립시켜 정성적 및 정량적으로 파악하기 위해 연속발진 모드의 레이저빔 사용시 열전도에 의한 손실을 고려하였으며, 문제를 단순화해 빔 또는 가공소재의 상대적인 움직임이 없는 천공 (또는 에칭제거)의 경우에 대하여, 수치모사를 통해 여러 가지 빔 변수의 변화가 가공결과에 미치는 영향을 살펴보았다. 레이저 빔의 초점의 위치를 표면에서 멀리하면 가공깊이는 감소하게 되며, 같은 간격일 때는 소재의 내부에 위치시키는 것이 다소 유리하다. 또한 빔의 발산각이 작고, beam quality factor 값이 1에 가까울수록 깊은 가공을 얻을 수 있음을 파악하였다. In laser machining such as drilling with CO_2 or Nd:YAG laser, and etching or ablation with Excimer laser, one of the most important parameters affecting the machining results is known to be beam characteristics. In this paper a study is performed through a numerical simulation with the appropriate model to investigate the effects of beam parameters qualitatively and quantitatively, especially in the process of laser drilling of ceramics and ceramic composites. Results of different beam conditions reveal that the machined hole becomes deeper as (ⅰ) the beam divergence gets smaller,(ⅱ) beam quality factor approaches unity, and (ⅲ) beam focus lies nearer to the surface of the workpiece.

지역사회의 상징 구성 모형으로 본 지역 정체성

강희경 한국사회문화학회 2000 사회와 문화 Vol.12 No.-

It has been argued that the movement of human beings and commodities on a golbal scale weakens cultural differences among localities. However, struggles of 'identity politics' against globalization have surfaced especially in the cultural sphere. Examples are women's movements and aborigines' movement in Australia. Another example is the attempts to clarify local boundaries through symbolic construction. It is argued that local community exist in the minds of community members, not in the 'geography'. The boundaries of local communities may be symbolized in four ways. The first is to revive local traditions. Examples are 'Chong-hak-dong maeul' in Kyung-Nam province and the play at tug of war in Chongdo, Kyulg-Buk. Secondly, drawing local people into rituals involving themes of local traditions and locally specific industries may be a way to symbolize the local boundaries as illustrated by 'Chun-hyang festival' in Namwon, film festival in Busan. and Zig-zi festival in Chongju. Thirdly, the symbolic reversal of social rotes such as 'Ha-whe byul-sin-gud' mask play in Andong, Kyung-Buk is another way to symbolize local community. Lastly, there is a strategy of revealing local stigma and change it into the object of respect. For example, Kuangju is made the holy land of democracy, and 'the hometown of arts', 'May Festival,' and 'Art Vienalle' are ways to construct local identity in Kuangju.

B 형 간염 에 있어서 IgM anti HBc 의 발현도 및 임상적 의의

김경희,강진경,문영명,송경순,김용범,최흥재,황용 대한내과학회 1986 대한내과학회지 Vol.30 No.1

Testing for IgM antiHBc was useful to detecting the patients with negative and positive HBsAg viral hepatitis and may improve serodiagnostic accuracy when acute NANB and delta agent hepatitis occur in previousely unrecognized HBsAg carriers. Moreover, it may be a useful test in defining potentially high risk sources of exposure to hepatitis B virus. But it is not useful in distinguishing recent from remote infection because IgM antiHBc occasionally was found in chronic liver diseases, IgM antiHBc was found by ELISA in 32 patients with acute viral hepatitis B, 61 with chronic hepatitis B, 18 patients with liver cirrhosis, 36 healthy HBsAg carriers and l49 patients with positive antiHBc alone. We continuously evaluated HBsAg and liver function of the patients who had negative IgM antiHBc acute hepatitis. The results are summarized as follows: 1) IgM antiHBc was positive in 84.4% of acute hepatitis B, 4% of chronic hepatitis B, 5.5% of positive HBsAg liver cirrhosis, 2. 8% of HBsAg healthy carriers but was all negative in patients with positive antiHBc alone. 2) Three patients with negative HBsAg acute viral hepatitis was diagnosed by positive IgM antiHBc as acute viral hepatitis R. 3) During the follow-up of 5 patients with negative IgM antiHBc acute hepatitis, 2 patients were diagnosed as type B acute viral hepatitis because of disappearance of HBsAg and normalization of liver function. And another 3 patients were diagnosed as non-B acute viral hepatitis superimposed on HBsAg carrier or natural course of chronic hepatitis.

수퍼바이저와의 협동관계가 사회복지사(수퍼바이지)의 업무만족 및 소진에 미치는 영향

강선경(Kang Sun Kyung) 한국사회복지학회 2008 한국사회복지학 Vol.60 No.2

본 연구의 목적은 협동작업(Work Alliance)으로 개념화된 바와 같이, 사회복지 종사자의 업무만족(Working Satisfaction)과 소진(Burnout)에 관한 수퍼바이저와 수퍼바이지간의 협동관계(Corporative Relationship)의 효과를 탐구하는 데 있다. 이를 위해 서울과 경기지역에 위치한 종합 사회복지관 및 상담 센터를 중심으로 68명의 수퍼바이저와 80명의 수퍼바이지들을 대상으로 일련의 위계적 선형모형(Hierarchical Linear Model: HLM)을 이용하여 독립변수(수퍼바이저와 수퍼바이지간의 협동관계)가 종속변수(업무만족 및 소진)에 미치는 영향을 조사하였다. 연구결과, 수퍼바이지가 수퍼바이저에게 가진 친밀한 느낌이 그들의 업무만족과 관계가 있다고 나타났다. 그러나, 수퍼바이저와 수퍼바이지 간의 협동이 당연히 소진 정도를 낮추는 것과 연관되어서는 통계적인 유의미를 발견할 수 없었다. 또한 업무만족과 소진 간에는 반비례적인 부의 관계가 있음이 나타났다. 마지막으로 본 연구의 의의와 후속연구에 대한 시사점을 덧붙였다. The purpose of this study explored the effects of supervisory relationship, conceptualized as working alliance, on social workers' working satisfaction and burnout. The consented participants were 68 supervisors and 80 supervisees working at Social Service Centers located in Seoul and Kyung-ki Province. Hierarchical linear model analyses of survey results from supervisors (n=68) and workers (n=80) revealed that the workers' sense of rapport within the supervisory relationship is related to working satisfaction. While it was expected that the supervisory relationship would also relate to levels of burnout, no association was found in the analyses. However, strong negative correlations were found between the supervisees' feelings of rapport within the supervisory relationship and both emotional exhaustion and depersonalization. The implication of future research and of social work practice and policy were added.

Seong Soo Kang1*, Se Eun Kim, Ara Go, Kyung Mi Shim, Chun Sik Bae, Chang Jong Moon, Sung-Ho Kim, Jong-Choon Kim, Jin-Cheol Yoo, Seung Sik Cho 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.3

Probiotics, enzymes, organic acids, oligosaccharides, antioxidants, and other functional materials are actively being explored as alternatives to antibiotics. Probiotics include live beneficial microorganisms that colonize the intestinal tract and competitively inhibit attachment and growth of harmful microbes. Probiotics also increase feed efficiency by assisting in nutrient absorption and digestion. The current study was conducted in order to evaluate the effect of a new probiotic, CS-A, as a dietary supplement of a fermented product on growth performance, feed intake, and feed conversion efficiency in broiler chickens, and to evaluate its value as an alternative for antibiotics used as a feed additive. Antibacterial and anti-inflammatory effects of CS-A were investigated in vitro and the in vivo effects of a constant concentration of supplemented CS-A on growth rate and feed efficiency were evaluated. In addition, the safety of CS-A was assessed by examination of common symptoms and mortality. Determination of minimal inhibitory concentration revealed an excellent antibacterial effect of CS-A. Cytotoxicity was low and anti-inflammatory effects were achieved at the effective concentration of CS-A. Supplementation with 0.1% CS-A resulted in a feed efficiency score of 1.84 in broilers, compared to 2.00 in the control group. There were no adverse clinical findings, necropsy findings, hematology, and altered serum biochemistry parameters, and no mortality. Thus, it is concluded that CS-A is safe and effective as a feed additive.
