장정민 한국외식경영학회 2022 외식경영연구 Vol.25 No.6

본 연구는 최근 세계적으로 이슈되고 있는 ‘비건음식’에 대한 소비자의 인식을 빅데이터를 통해 분석하였다. 텍스톰을 활용하여 다음과 네이버에서 ‘비건음식’이라는 단어로 2020년부터 2022년까지의 텍스트 자료를 수집하였다. 연구를 통해 비건음식 및 식품 연구자들에게 관련된 자료를 제공하고 실무적인 시사점을 제시하고자 하는 목적으로 연구되었다. 수집된 자료는 총 3,866건, 1.469KB로 수집된 자료를 바탕으로 데이터 정제 과정을 거친 후 빈도분석, TF-IDF분석을 시행하여 노출빈도가 높은 상위 50개 핵심단어를 추출하였다. 이후 연결정도 중심성 분석을 통해 네트워크의 밀도지수를 파악하였으며, 구성노드 간 연결 관계를 중심성을 바탕으로 네트워크 시각화 후 핵심노드의 연결 관계를 통해 CONCOR분석을 하여 4개의 군집으로 분류하였다. This study analyzed consumers' perceptions of 'Vegan food', which has recently become a global issue, with big data. Text data from 2020 to 2022 were collected from Daum and Naver with the word ‘Vegan food’ in using Textom. The results of this study are intended to provide relevant data to vegan food and food researchers. A total of 3,866(1,469KB) cases of collected data were analyzed for the data refinement process based on the collected data. Afterwards, frequency analysis and TF-IDF analysis were performed to extract the top 50 key words with high frequency of exposure. The density index of the network was identified through the degree of connectivity centrality analysis, and the connectivity relationship between component nodes was visualized based on centrality. and then the CONCOR analysis was performed through the connectivity relationship of core nodes to classify into four clusters.

소비자 조절초점에 따른 광고 내 그림 메시지 효과 연구

장정민,이진화 한국상품학회 2014 商品學硏究 Vol.32 No.4

연구목적: 가격 할인에 대한 정보를 제공하는 인쇄광고에서 단순 그림 메시지가 할인매력도 지각에 미치는 영향에 대한 고찰을하였다. 이때, 조절 초점에 의해 그 영향이 조절될 것으로 기대하였는데, 그 이유는 조절 초점 성향에 따라 더 민감하게 반응하는 정보의 유형이 다르기 때문이다. 즉 향상 초점의 소비자들은 긍정적인 정보에 좀 더 민감하게 반응하고, 예방 초점의 소비자들은 부정적인 정보에 좀 더 민감하게 반응한다고 알려져 있다. 본 연구에서 제안하고 있는 사선 그림 메시지는 대상에 대한 삭제, 부정을 의미하고 있으므로, 예방 초점 소비자들이 더 민감하게 반응할 것으로 예측하였고, 이를 검증하기 위해 소비자 조절 초점 성향에 따른 단순그림 메시지의 유무에 대한 반응의 차이를 비교하였다. 연구 설계 및 방법론: 연구목적의 달성을 위해 가격 할인 정보를 제시하는 자극물로써 인쇄광고를 제작하여 설문 기반의 실험 에 사용하였다. 153명의 학부생을 대상으로 그림 메시지의 유무에 따른 두 조건에 무작위 배정하고, 소비자의 조절초점은 설문을 통해 응답을 얻고 사후적으로 두 집단으로 분류하여 분석에 반영하여 이들의 상호작용이 지각된 할인 매력도에 미치는 영향력을ANOVA를 통해 검증하였다. 분석 및 연구 결과: 예방 초점의 소비자들은 사선모양(단순 그림 메시지)의 추가 정보가 제시된 경우, 제시되지 않은 때보다 가격할인에 대한 매력도를 더 호의적으로 평가한 반면, 향상초점의 소비자들은 사선 모양 정보의 제시 여부에 의한 유의한 차이를 보이지 않았다. 그 결과 단순 그림 메시지 효과에 대한 조절초점의 조절효과를 제안한 연구가설은 지지되었다. 시사점 및 연구의 한계점: 본 연구는 광고 내에서 추가적 정보로써 제공되는 단순 그림 메시지가 소비자의 할인 매력도 지각에 미치는 영향이 소비자의 동기적 성향에 따라 조절된다는 것을 확인하였다. 또한 그간 광고의 메시지 모드 연구들에서 비언어적 요인으로써 많은 의미를 담고 있는 복합적인 이미지(사진)를 사용해온 것과 달리 보다 간결한 구조를 띄며 실제 광고에서 흔히 사용되는단순한 그림 메시지로써 사선 모양을 활용하여 그 역할을 제시하고, 가설을 검증하였다는 데에 의미가 있다. 그러나, 본 연구는 실험 자극물로 학생용 책상 의자만을 이용하고, 종속 변수로 할인 매력도만으로 연구 결과를 확인하였다는 한계점을 가지고 있다. 따라서 향후 연구는 다양한 제품을 대상으로 하는 광고 자극물을 실험할 필요가 있으며, 소비자 인식에 대한 또 다른 종속변수를 적용해볼 수 있다. 향후 연구방향: 향후 연구들은 다양한 제품을 대상으로 한 광고를 자극물로 사용하고, 종속변수로서 소비자 인식에 대한 다른 개념을 적용해 연구 결과를 보다 일반화 할 필요가 있다. 공헌점: 본 연구는 인쇄 광고 내 그림 메시지가 소비자 인식에 미치는 영향이 소비자 조절초점에 의해 조절됨을 확인하였다. Purpose: This paper aims to examine the effect of additive picture message in the discount advertisement on consumers' perceived discount attractiveness. Authors assume that the effect could varies with the regulatory focus(promotion vs. prevention). Extant researches suggest that while promotion focused consumers process positive information more carefully, consumers with prevention focus react sensitively to negative information. Therefore, we assumes that only prevention focused consumers show distinct response to the advertisement added diagonal line which means elimination or denial of the object. Design/methodology/approach: In order to validate hypotheses, we experiment differences between the perceived discount attractiveness of two regulatory focuses when simple picture message is given additionally in paper advertisement. 153 undergraduate students participate, and we use ANOVA to analyze the survey data. Results/findings: Findings from the empirical test are as follows. First, prevention focused consumers perceive discount attractiveness more favorably when they see the advertisement containing diagonal line(picture message) than they are given the advertisement with no additional picture message. Second, on the other hand, promotion focused consumers shows no significant difference in perceive discount attractiveness between two advertisement types. Therefore, our hypotheses are supported. Research implications/limitations: This study has some implications that we show the different effect of additional picture massage on consumers' perceive discount attractiveness depending on consumers' regulator focus. And we also use vary simple picture massage like diagonal line and prove its effect unlikely prior researches use complex image(e.g. photograph) mostly. .However, this study has limitations of using singular stimuli and dependent variable. Future work/research: Further research will be tested with another products and be applied various dependent variable. Originality/value: This study figure out that regulatory focus moderat the effect of picture message on consumers' perception

한국어 발음 교육에서의 정확성과 유창성에 대한 새로운 접근 - 표준 발음과 현실 발음을 중심으로 -

장정민,배영환 중앙어문학회 2022 語文論集 Vol.91 No.-

This study aimed to promote a test-character discussion based on the proposal standard pronunciation and actual pronunciation can be used to evaluate pronunciation accuracy and fluency in Korean language education. Most existing research on such discussions attempts to analyze pronunciation accuracy and fluency using segmental phonemes and suprasegmental, respectively. Considering that these discussions have identified different factors influencing pronunciation fluency, a new level of discussion on accuracy and fluency is needed Alternatively, this article proposes the analysis of pronunciation accuracy and fluency through standard pronunciation and actual pronunciation, respectively. In particular, pronunciation fluency corresponded to narrow actual pronunciation, which is a “non-standard pronunciation predominantly used by Korean native speakers.” Accordingly, several pronunciations in Korean phonological phenomena (e.g., consonant cluster simplification, tensification, /n/-insertion, and restructuring) were reviewed, classified into either accurate and fluent pronunciation, and points were noted for teachers referencing the application of this approach in teaching and pronunciation evaluation in Korean language. 이 논문은 한국어 교육에서 발음의 정확성과 유창성을 평가하는 한 방안으로, 표준 발음과 현실 발음의 대응을 제안하는 시론적인 성격의 논의이다. 기존의 정확성과 유창성 관련 논의는 대부분 분절음을 정확성에, 초분절음을 유창성에 대응하여 분석하고자 하였다. 그러나 연구마다 유창성에 영향을 미치는 요소가 다르게 나타나고 있다는 점에서 정확성과 유창성에 대한 새로운 차원의 논의가 필요함을 확인하였다. 따라서 음운 현상 차원에서의 접근을 강화하여 정확성과 유창성을 표준 발음과 현실 발음에 대응해 보려는 시론적인 성격의 논의이다. 특히 유창성은 ‘한국어 모어 화자가 우세하게 사용하는 비표준 발음’인 좁은 의미의 현실 발음과 대응하였다. 이러한 논의에 따라 한국어의 음운 현상 중 자음군 단순화, 경음화, ‘ㄴ’ 첨가, 그리고 재구조화에서 나타나는 몇 가지 발음을 검토하여 정확한 발음과 유창한 발음을 분류해 보고 교수 및 평가 시 유의할 점을 살펴보았다.

There are many strong point in making university village. First, it takes charge of functionality of Campus. Second, it bear the responsibility for Art and Science, Residence, Leisure, Social Relationship. A making village is a good point to student of the Pyeongtaek University, nearby a residents of the Pyeongtaek University. So, we study about the university village in another district. Also, we survey the nearby residents of the Pyeongtaek university. We proposal the making university village for development direction of the university district. We surveyed the residents living in nearby Pyeongtaek University. So, we analyze the result using the SPSS/PC 15.0. We analyze the question paper using the significant level 0.05. Also, we make the decision about the development direction in Pyeongtaek University village. We obtained the development direction of the Pyeongtaek University village through the result of survey. We proposal the direction of the development in Pyeongtaek University village. University village is very important to students of university, residents of nearby village, and students of middle and high school. So, many student want to make University village. Through this study, we know that they want to make the university village which is consist of culture space, theater, library, coffees-hop. Also, they want to make the culture load like Rodeo located in Bundang. Many residents want to make the university village like America. In the future, we consider about benchmarking to America for making University village.

Does Ultrasound-Guided Directional Vacuum-Assisted Removal Help Eliminate Abnormal Nipple Discharge in Patients with Benign Intraductal Single Mass?

장정민,문우경,박정선,정세영,장미정,조나리야 대한영상의학회 2009 Korean Journal of Radiology Vol.10 No.6

Objective: To evaluate whether the removal of an intraductal mass using an ultrasound (US)-guided directional vacuum-assisted device can eliminate symptoms in patients presenting with abnormal nipple discharge. Materials and Methods: Between March 2004 and October 2006, 36 patients who presented with abnormal nipple discharge, underwent US-guided, 11-gauge vacuum-assisted biopsy for a benign intraductal single mass on US. The ability of the procedure to eliminate nipple discharge was evaluated by physical examination during follow-up US. Lesion characteristics, biopsy variables, and histologic features were analyzed to identify factors affecting symptom resolution. Results: Of the 36 lesions, 25 (69%) were intraductal papillomas, 10 (28%) were fibrocystic changes, and one (3%) was a fibroadenoma. The nipple discharge disappeared in 69% (25 of 36) of the women at a mean follow-up time of 25 months (range 12-42 month). There was no difference in the lesion characteristics, biopsy variables, and the histologic features between groups that eliminated the symptom compared those with persistent nipple discharge. Conclusion: US-guided directional vacuum-assisted removal of an intraductal mass appears to eliminate nipple discharge in only 69% of patients and thus, it should not be considered as an alternative to surgical excision.

Purpose – There have been numerous studies investigating the effects of corporate social responsibility initiatives on corporate associations or corporate images. In line of this research stream, current research examined the potential impact of customer participation in the process of corporate social responsibility initiatives on attitude toward the company. This research differentiates from previous studies that it is the first to connect corporate social responsibility and customer participation. Specifically, we suggest a structural model on corporate associations which was classified into corporate ability associations and corporate social responsibility associations that the more the customers participate in initiating corporate social responsibility, corporate associations were formed more positively. And this leads to the increase of revisit intentions through customer satisfaction. Research design, data, and methodology – To test our research model, we collected data of real consumers of a large discount store in Korea. At the large discount store, customers were given an opportunity to participate the discount store’s CSR activity program. We performed field survey and collected data of 146 respondents. We analyzed the data using PASW statistics 21.0 and AMOS 16.0 in order to test our structural model. Results – The results showed that consumers who participated more in initiating corporate social responsibility revealed higher score for corporate ability associations and corporate social responsibility associations. These corporate associations had a positive effect on customer satisfaction, which leads to higher attitude toward revisit intentions. Specifically, hypothesis 1.1 "As Customer participation in CSR process increases, the evaluation of CA associations will be positive,"was supported. Hypothesis 1.2 "As Customer participation in CSR process increases, the evaluation of CSR associations will be positive," was supported. Hypothesis 2.1 "As the evaluation of CA associations is positive, satisfaction with the firm will increase," was supported. Hypothesis 2.1 "As the evaluation of CSR associations is positive, satisfaction with the firm will increase," was supported. Hypothesis 3 "As satisfaction with the firm increases, revisit intentions with the firm will increase," was supported. Conclusions – This research is the first to study the relationship between customer participation in CSR process, CSR, and consumer reactions. This research also contributes to customer participation and corporate social responsibility literature by suggesting customer participation as an antecedent and empirically demonstrating the positive relationships between the constructs. The findings of this research may offer managerial implications for marketing practitioners. When performing corporate social initiatives, it is better to let the customer participate in the process which leads to higher corporate ability associations and corporate social responsibility associations, also higher satisfaction and revisit intentions. Our results provide useful information to practioners that spontaneous participation of consumers makes CSR initiatives effective and successful. Limitations and ideas for further research remain in this research. For example, our focus on the logic was cognitive evaluations(e.g. corporate associations) but affective dimensions might be considered since recent researches are investigating the relationship between customer participation and affective reaction as a response. Despite the limitations, this research have unique and applicable implications for academics and practitioners.

하이브리드 후렉틀 확장 크로스 안테나

장정민,이상설 한국전자파학회 2000 한국전자파학회논문지 Vol.11 No.8

마이크로 스트립 선로로 구성된 십자 형태의 진행파형 크로스 안테나를 기본구조로 하여 이를 후렉틀 확장시킨 안테나를 새롭게 제안하였다. 진행파형으로 후렉틀 안테나를 구성할 때 확장 차수가 증가하면 전류의 전파길이가 증가한다. 진행파 안테나의 동작 매커니즘에 따른 여러 손실로 인해 전파 길이가 증가하면 전력분포가 불균일하게 되어 안테나의 성능을 저하시킨다. 안테나 성능 저하를 줄이기 위해 전체 후렉틀 구조를 몇 개의 후렉틀 소그룸으로 나누고 각각의 후렉틀 소그룸을 전력분배 회로로 연결한 하이브리드 형식의 후렉틀 안테나를 제안하였다. 2차, 3차, 4차 확장된 하이브리드 후렉틀 크로스 안테나를 제작하여 특성을 측정하였고 후렉틀 확장차수의 증가에 따른 안테나 성능 변화를 해석하였다. A new fractal geometry of the traveling wave type cross antenna is newly presented. In the conventional type of the traveling wave antenna, the electrical length of the radiating conductor increases as the order of fractal expansion increases. But, increased length of the current path degrades the performance of the antenna from the various loss mechanism of the traveling wave type antenna. To reduce the antenna performance degradation, the new hybrid fractal antenna, which divides the entire fractal structure into some smaller ones and connects each smaller fractal group with a power divider is presented. The secondly, thirdly and fourthly expanded hybrid fractal cross antennas are fabricated and their performances are examined by measurements. Influences of the fractal order to the antenna performance are examined.
