한국어 구어 대화의 종결어미 사용 양상 연구

한승규 인문사회 21 2020 인문사회 21 Vol.11 No.4

한국어 문법 연구는 문어를 중심으로 연구되어 구어 문법 연구의 필요성이 증대되고 있다. 이에 이 연구는 한국어 구어 대화에서 종결어미를 살펴 그 사용 양상과 특징을 밝히는 것을 목적으로 한다. 연구 자료로 국립국어원에서 구축한 「21세기 세종계획」의 「현대 국어 구어 말뭉치」를 이용하였다. 한국어 구어 대화에서의 종결어미 사용 양상을 일상대화/전화대화의 담화 유형에 따라, 대화 참여자의 성별에 따라 살펴보았다. 종결어미는 연구 자료에서 총 1,991개가 나타났으며 ‘–어, -야, -아, -지’가 높은 빈도로 나타났다. 전화대화는 일상대화에 비해 비대면의 특성이 나타났다. 참여자의 성별에 따라 살펴본 결과 여여 대화에서는 종결어미 ‘-다’가, 남남 대화에서는 ‘-지’가 특징적으로 나타나는 것이 확인되었다. 이 연구는 대화를 연구 자료로 하여 문법 연구에 있어 실제성의 측면에서 의의가 있다고 볼 수 있다. The study of Korean grammar is focused on written rules, and the need for a study of spoken grammar is increasing. Therefore, the purpose of this study is to examine the final endings in spoken Korean conversations and to clarify their usage patterns and characteristics. As the research data, Contemporary Korean Colloquial Corpus of 21st Century Sejong Plan constructed by the National Institute of the Korean Language was used. The use of the final endings in spoken Korean conversation was examined according to the type of conversation in daily conversation/telephone conversation, and according to the gender of conversation participants. A total of 1,991 final endings were found in the study data, and ‘–uh, -ya, -ah, -ji’ was found with a high frequency. Phone conversations were characterized by non-face-to-face conversations compared to daily conversations. According to the gender of the participants, it was confirmed that the final ending ‘-다’ in female and female conversations, and ‘-지’ in male and female conversations appeared characteristic. This study can be seen to be significant in terms of practicality in grammar research, using dialogue as the conversation data.

rhGM-CSF(Leucogen^ⓡ)의 비감염성 상처 치유 효과에 관한 연구

한승규,김병수,김애리,서재홍,최철원,신상원,김열홍,김우경,김준석,Han, Seung Kyu,Kim, Byung Soo,Kim, Aeree,Seo, Jae Hong,Choi, Chul Won,Shin, Sang Won,Kim, Yeul Hong,Kim, Woo Kyung,Kim, Jun Suk 대한면역학회 2001 Immune Network Vol.1 No.1

Background: rhGM-CSF has been shown to enhance the migration and proliferation of endothelial cells and to promote keratinocyte growth. This study was tried to evaluate the effect of rhGM-CSF dressing on the uninfected wounds. Methods: Thirty Sprague-dawley white mice(250-300g) were selected in this study. The number of wound with the diameter of 5 mm, was 3 in left and 3 in right at the symmetric sites, respectively. The site of rhGM-CSF dressing was decided by a randomization. rhGM-CSF($Leucogen^{(R)}$) was diluted in the distilled water($5{\mu}g/mL$). The experimental wound group was dressed by l mL of distilled water mixed with rhGM-CSF and control wound group was dressed by l mL of distilled water. The dressing was done, every 24 hours. The criteria of comparison were the duration of wound healing duration, histologic findings and the bacterial culture of wound sites. Results: The duration of wound healing was $10.3{\pm}1.7days$ in experimental group and $10.2{\pm}2.8days$ in control group, without significant difference. There was no specific difference of histologic findings between both groups. The pathogen was not found, at all. Conclusion: It seems to be that rhGM-CSF has no prominent effect on the uninfected wound healing in the mice without immune suppression.

Several suspension biomaterials are available for soft tissue augmentation. Although these gel type implants have been shown to be relatively safe and convenient, their varying degrees of resorption require repeated percutaneous injections. Previous in vivo and in vitro studies have shown that the injection of cultured human adipocytes can produce a sufficient volume effect with extended in vivo stability. This pilot study was undertaken to evaluate the clinical efficacy of this method. Between November 2007 and January 2008, 5 patients were treated with implants of autologous differentiated adipocytes for wrinkle correction and forehead augmentation. The contour changes of the treatment sites were investigated in accordance with the passage of time, as was the occurrence of complications. The degree of patient satisfaction was also evaluated. The injected bioimplants remained in situ. Two weeks after injection, they began to show evidence of a soft tissue augmentation effect. All patients were satisfied with the overall results of this method, and no complications occurred during the follow-up period. The results obtained indicate that differentiated human adipocytes may be successfully injected as living grafts for long-term implants, and that this method is a well tolerated, effective way of performing soft tissue augmentation.

The two major concerns in skin grafting are poor color match in the recipient site and the donor site morbidity. A new skin graft(dermis graft; deepithelialized split thickness skin graft), was used to minimize these problems. The important aspects of this method involve immediate return of epidermis to the donor site and restoration of the recipient site's epidermis by inducing epithelialization from adjacent skin. From April of 2001 to March of 2004, dermis graft and a conventional split thickness skin graft(STSG) were performed in 53 and 33 patients, respectively. The healing time, the scar condition, and the patients' satisfaction were compared. Regarding the recipient sites, the wounds of the dermis graft(n=53) and STSG(n=33) had reepithelialized after 15.5±1.9 and 11.8±1.6 days, respectively. The scarring were less severe on the dermis graft in terms of pigmentation, height, and vascularity(p<0.05). No significant difference in pliability was detected. The patients' satisfaction with the dermis graft was also better. Concerning the donor sites, the wounds healed within 7.5±0.8 and 12.8±1.1 days, respectively. In terms of scar quality and patients' satisfaction, the dermis graft(n=26) showed better results. The dermis graft is superior to conventional STSG both aesthetically and functionally in both the recipient and donor sites.

Purpose: The aim of this study is to compare the effects of bone marrow stromal cells(BSCs) and fibroblasts on wound healing activity in vivo, especially on epithelization.Methods: The fibroblasts and BSCs were harvested from patients and cultured. Ten Spague-Dawley white rats were used. A 5 mm punches were made to excise skin and subcutaneous tissue in a round fashion at six sites on the back area of each rat. Four hundred thousand cells suspended in 0.05 ml fibrinogen were applied to the created wounds. The cells in group I, II, and III were no cells, fibroblasts and BSCs. The lengths of epithelial gap at the widest wound site were compared with autopsy specimens obtained on the 6th day after cell therapy under light microscope. Statistical comparisons were performed using the Mann-Whitney U-test, and the p value<0.05 was considered statistically significant.Results: The best epithelization was also seen in the BSC group, followed by fibroblast and no cell groups.Conclusion: These results demonstrate that BSC has superior effect on stimulating wound healing than fibroblast, which is currently used for wound healing.

본 연구는 뉴스 기사 빅데이터에서 키워드 ‘한국어’를 분석하여 한국 사회에서 한국어교육이 차지하는 위 상을 밝히는 것을 목적으로 한다. 1990년대, 2000년대, 2010년대의 세 시기로 구분하여 키워드 ‘한국어’ 관련 관계 도 분석, 연관어 분석, 트렌드 분석을 시도하여 한국어교육의 위상과 문화적 함의를 도출하였다. 그 결과 2000년대 에서 한국어교육의 큰 변화와 흐름을 확인할 수 있었다. 이 시기는 한류의 확산과 외국인 유학생, 결혼 이민자, 외 국인 노동자의 증가와 한국어교육을 지원하고 운영하는 다양한 기관이 생기거나 확대된 시기이다. 본 연구를 통하 여 지난 30년 동안의 한국어교육의 동향과 흐름을 파악할 수 있었으며 향후 한국어교육이 나아가야 할 방향을 고 찰할 수 있다는 점에서 의의가 있다.
