This paper aims to analyze the effects of the major-job match on job satisfaction in the tourism-related industry based on the 2015 Graduates Occupational Mobility Survey data. This study has two distinct things. First, we considered major-job matches in two ways, subjective and objective methods, and compared the effects on job satisfaction. It considers the possibility of bias caused by self-reported of respondents in a subjective major-job match. Second, we composed a group of more than one year of experience. Both groups, which are an experienced group and an integrated group, are analyzed respectively to enhance the reliability of subjective major-job match measurement. That is because a new worker can make an inaccurate evaluation of her major-job match and job satisfaction due to incomplete job adaptation. The findings are as below. First, in the case of experience group, subjective major-job match had a positive effect on job satisfaction, while objective major-job match had no significant impact on that. Second, the factors that impact job satisfaction are company size, working hours, overtime payment, and GPA.

벼리】이 연구의 목적은 영어권 학습자의 비음동화 발음 실태를 살 펴보고 오류 분석을 통한 비음동화 발음 교육 방안을 마련하는데 있 다. 비음동화 환경이 포함된 문장을 영어권 학습자에게 제시하고 발 화를 녹음하여 분석하였다. 녹음된 자료를 바탕으로 환경별 비음동화 발음 오류를 분석하였다. 오류 분석 결과를 바탕으로 통합형 한국어 비음동화 교육방안을 마련하였다. The purpose of this study is to suggest an appropriate teaching plan for nasal assimilation aiming at English-spoken Korean language learners through overtaking analysis on erroneous Korea nasal assimilation pronunciation attempted by those learners from contrastive linguistic perspectives. In the second chapter, I am going to examine both one difference between English and Korea syllable structure and the other difference between assimilations of those two languages in order to find difference between Korea and English nasal assimilation. Through this process, it was possible to predict English-spoken learner’s erroneous pronunciation. In the third chapter, I am going to conduct analysis on erroneous pronunciation through testing English-spoken learners’ Korean nasal assimilation pronunciation. Korean nasal assimilation environment can be largely categorized into three parts: bilabial consonant, alveolar consonant, and soft palatal consonant. Examination paper is constructed varied depending on learning level: beginner and intermediate level. Then analysis is conducted individually on erroneous pronunciation by learning level. The analysis of the result is jointly conducted by author of this study and the other two Korean language teachers with sufficient experience of field teaching. We successfully verified reasons for erroneous Korean nasal assimilation pronunciation varied depending on learning level and different phonological condition. Depending on learning level, erroneous pronunciation frequency is found to be relatively higher for beginner level learners than intermediate levellearners. Meanwhile, depending on phonological condition, erroneous pronunciation frequency for other phonological samples is found to be higher for soft palatal consonant, alveolar consonant, and bilabial consonant in order described. Based on this result of test, I am going to suggest an appropriate teaching plan for Korean nasal assimilation aiming at English-spoken Korean language learners in the fourth chapter. Then, I am also going to define phonological prerequisites for awareness of nasal assimilation pronunciation. Given a finding that frequency is varied depending on phonological condition, I claimed that nasal assimilation should be required to be introduced in order of bilabial consonant, alveolar consonant, soft palatal consonant to those English-spoken Korean language learners. And I suggested an integrated teaching method model for Korean nasal assimilation with five phases categorized. This integrated Korean language class is composed of five applicable learning phases: diagnosing with models, listening to spoken words, understanding principle of nasal assimilation, practicing nasal assimilation, and internalization of law of nasal assimilation. Based on such a teaching method model, I created an integrated teaching plan for Korean nasal assimilation. The integrated teaching plan for Korean nasal assimilation suggested in this study would be expected to be applicable to entire phases of Korean language class in order to improve English-spoken Korean language learners’ pronunciation availability. I investigated whether English-spoken Korean language leaners with beginner and intermediate level proficiency are able to pronounce Korean nasal assimilation in correct manner. In conclusion, further active study is required to be conducted over entire phases of teaching plan for Korean nasal assimilation through expanding scope of investigation into high level English-spoken Korean language learners.

In this study, first, we adopted a twin configuration of a Darrieus hydrokinetic turbines that can bring about an improvement in efficiency through positive interaction and obtained the optimal shape through parametric analysis of the small-scale turbine model by computational fluid dynamic simulations. Next, the effect of performance improvement was examined for symmetrical and asymmetrical ducts. The results show that the asymmetrical duct that utilizes diffusion effects has a comparative advantage in terms of efficiency and drag over the symmetrical one. However, the advantage of the Darrieus turbine, which has flow-directional independency, is lost in the case of the presented configuration; thus, we introduced the idea of a passive yaw-controller that adapts to the variation of the flow-direction that does not require additional energy consumption. In conclusion, such efforts and adjustments to enhance the performance of the Darrieus turbine by utilizing the interaction and diffusion effects discussed in this study will be helpful in securing competitiveness against other types of hydrokinetic turbines.

정다솜,권순희 한글학회 2022 한글 Vol.- No.336

This study analyzed trends in domestic speech communication research using semantic network analysis. Using NetMiner, 2,210 registered KCI papers that contained the keyword “speech” were collected and 370 were selected for analysis through data preprocessing. Vocabulary frequency, co-occurring word, and degree-centrality analyses were performed on the selected papers. Vocabulary frequency analysis showed that many studies on speech were conducted in the context of learning situations and that studies related to daily conversations were relatively rare. Vocabulary frequency analysis showed that the most common keyword was “education” followed in order of decreasing frequency by “dialogue,” “process,” “center,” “Korean language,” “teacher,” “ability,” and “evaluation.” In addition, It was confirmed that studies of speech communication in learning situations were conducted by presenting teachers as surface topics. Keywords frequently used in daily conversation-related research were identified. Simultaneous word analysis showed that many studies were about how to teach speech. Degree centrality analysis showed that the most common keyword in speech research was “education” followed in order of decreasing frequency by “center,” “dialogue,” “language,” “analysis,” “Korean,” “speech,” and “class” and that conversation participants were analyzed in teaching and learning situations. These analysis results indicate that speech communication research should be further discussed while reflecting the conversation phenomenon in the expanded space such as cyberspace. Considering the environment in which communication has become a daily life in the online space, discussions about speech communication phenomena occurring in various media should be dealt with in multiple layers. 이 글은 언어 네트워크 분석 방법을 활용하여 국내 화법 연구의 동향을 분석하고, 후속 연구의 방향을 제언한 것이다. 넷마이너를 활용하여 ‘화법’을 키워드로 한 KCI 등재지의 학술 논문 2,210편을 수집하였고, 데이터 전처리 과정을 거쳐 화법 연구와 관련된 최종 분석 자료 370편을 선정하였다. 이 자료를 대상으로 어휘 빈도 분석, 동시 출현 단어 분석, 연결 중심성 분석을 하였다. 어휘 빈도 분석 결과 ‘교육, 대화, 과정, 중심, 국어, 교사, 능력, 평가’ 순의 키워드가 고빈도 어휘로 나타난 점과 학습 상황에서의 화법 연구가 교사를 표면적 주제로 제시하여 이루어진 점, 일상 대화 관련 연구의 키워드를 확인하였다. 동시 출현 단어 분석 결과 교수자 측면에서 화법을 어떻게 가르칠 것인가에 대한 교육적 차원의 논의가 주목된다고 보았다. 연결 중심성 분석 결과 ‘교육, 중심, 대화, 언어, 분석, 국어, 말, 수업’ 순의 키워드가 화법 연구에서 중심부를 차지하고 있는 주제어라는 점과 교수‧학습 상황에서의 다양한 대화 참여자 간 화법 분석이 이루어졌음을 확인하였다. 이러한 분석 결과를 바탕으로 현 시대의 화법 연구는 확장된 공간에서의 대화 현상을 반영하여 더욱 논의할 필요가 있다고 보았다. 온라인 공간에서 대화하는 것이 일상이 되어버린 시대적 환경을 고려하여 다양한 매체 안팎에서 이루어지는 또 다른 화법 현상을 주목한 논의가 다층적으로 다루어져야 함을 제언하였다.

This study aims to analyze metaphorical linguistic expression based on the conceptual metaphor theory on how this event is conceptualized in newspaper articles. This study was concerned with the newspaper articles on Yemeni refugees in Jeju Island, which have recently become an issue in Korean society. As a result, this study could find out that even the newspaper articles mainly aiming at objectivity and impartial reporting were often using metaphorical expressions. Prior to an examination of the concrete metaphorical expressions, this study classified the views of refugees in Korean society. A negative view of refugees, looking at them as mostly undesirable objects was noticeable. The metaphors mainly used in this context were ontological metaphors conceptualizing physical objects, including human physical experiences into the source domain and mapping them into the target domain. In the realized conceptual metaphors, the metaphor, [A country is people] appeared frequently as a sub-type of [The state is an organism]. In addition, the metaphors, [Refugees are fluid in a container], [Anger is a hot fluid in a container] and [Security is a blockade] could also be observed. Through this, refugees are considered beings that have negative impacts on the country and people, causing problems in the country and being difficult to control, while the state noticeably takes an exclusive attitude towards refugees by marking national boundaries to restrict their entry.

확률변경모형을 활용한 국내 풍력부품산업의 비용효율성과 결정요인 분석

정다솜,강상목 한국산업경제학회 2019 산업경제연구 Vol.32 No.6

본 연구의 목적은 2단계 확률변경비용함수 추정을 통하여 풍력부품제조 기업의 비용비효율을 도출하고 그 결정요인을 분석하고자 함이다. 코스피・코스닥에 상장된 24개의 풍력부품제조 기업을 대상으로 2009-2018년 기간 동안 10년간 패널 자료를 활용하였다. 패널 확률변경비용함수에 기초하여 비용비효율을 측정하고 그 시간변화를 확인하였고 비용비효율의 결정요인을 제시하였다. 분석 결과, 첫째 비용효율성의 전체 평균은 0.411이며, 각 기업별로 비용효율성이 아주 낮은 기업부터 높은 기업까지 고루 분포하는 것을 확인하였다. 또한 시간이 흐름에 따라 비용효율성이 증가하나 그 정도는 크지 않았다. 둘째, 연도, 설립연차, 기업규모, 생산품목이 비용효율성에 영향을 주는 요인으로 나타났다. 특히 생산품목 중 풍력부품의 핵심인 발전시스템(터빈)을 생산하는 기업의 경우 부품・기자재를 생산하는 기업에 비해 비용효율성이 현저하게 낮았다. The purpose of this study is to derive the cost inefficiency and analyze the determinants in domestic wind component manufacturing of companies through the estimation of the two-step stochastic frontier cost function. This paper targets for 24 wind component manufacturing companies listed on the Korean stock market and uses unbalanced panel data for ten years during the 2009-2018 period. We measured the cost inefficiency based on the panel stochastic cost function, checked the time trend, and presented the determinants of the cost inefficiency. As a result of the analysis, first, the average of the cost efficiency is 0.411, and the distribution of that is extensive. Also, as time goes by, the cost efficiency increased, but not so much. Second, the determinants of the cost efficiency were as followings: time, establishment year, size of the company, and production item. Notably, the cost-efficiency of the manufacturers producing turbines, a core of the wind component, is much lower than that of the companies producing equipment and materials.
