해파리에 대한 쥐치의 포식률을 파악하기 위하여 메두사, 에피라, 폴립 단계의 보름달물해파리(Aurelia aurita s.l.)를 쥐치(Stephanolepis cirrhifer)에게 공급하고 포식실험을 수행하였다. 모든 크기의 쥐치는 메두사를 적극적으로 포식하였으며, 포식률은 쥐치의 체중과 비례하였다. 평균 습중량 0.5, 1, 2.2 g의 쥐치 치어는 평균 $0.77{\pm}0.51g\;fish^{-1}h^{-1}$을 포식하였으며, 평균 습중량 150, 344 g의 쥐치 성어는 각각 $9.26{\pm}1.61$, $15.89{\pm}3.67g\;fish^{-1}h^{-1}$을 포식하였다. 유생에 있어서도 평균 습중량 3.7 g의 쥐치가 10분 이내에 100개체의 에피라를 포식하였고, 평균 습중량 2.2 g의 쥐치는 단위체중당 $5.73{\pm}0.59$ polyps $g^{-1}$ of fish $h^{-1}$의 폴립을 포식하였다. 반면에 쥐치 성어는 폴립을 포식하지 않았다. 이와 같은 쥐치의 해파리 포식이 현장에서도 가능한지 알아보기 위해 수행된 먹이 선호도 실험에서, 쥐치 성어는 다른 먹이인 굴(약 60%)과 갯지렁이(약 80%)를 주로 포식하였고 메두사 포식은 약 2%에 불과했다. 하지만 쥐치 치어는 다른 먹이인 곤쟁이류와 함께 에피라, 폴립도 포식하였으며, 폴립에 대해서는 지속적인 포식활동을 보였다. 그리고 쥐치 치어는 주변에 다른 먹이가 있어도 보름달물해파리 유생에 대한 포식이 활발했지만, $11^{\circ}C$ 이하에서는 섭식활동을 중지한 실험결과로부터 $11^{\circ}C$ 보다 수온이 낮은 3-4월경에 발생하는 에피라 유생에 대한 현장에서의 포식 가능성은 낮을 것으로 예상할 수 있다. 반면, 폴립의 경우 수온에 관계없이 연중 서식하기 때문에 현장에서 쥐치 치어의 폴립 포식이 가능할 것이다. 따라서 쥐치를 이용하여 보름달물해파리 구제작업을 시행할 경우, 폴립을 대상으로 하여 쥐치 치어를 이용하는 것이 가장 효과적일 것으로 판단된다. To determine the predation rate of threadsail filefish, we conducted feeding experiment of threadsail filefish, Stephanolepis cirrhifer on different life stages (medusae, ephyrae, and polyps) of Aurelia aurita s.l. in the laboratory. All size groups of threadsail filefish actively preyed on moon jellyfish Aurelia aurita s.l. and predation rate was proportional to the wet weight of threadsail filefish. Average wet weight 0.5, 1, 2.2 g of threadsail filefish preyed on average $0.77{\pm}0.51g\;fish^{-1}h^{-1}$ of medusae. Average wet weight 150 and 344 g of threadsail filefish preyed on $9.26{\pm}1.61$ and $15.89{\pm}3.67g\;fish^{-1}h^{-1}$ of medusae respectively. In ephyrae and polyps, average wet weight 3.7 g of juvenile of threadsail filefish preyed on 100 ephyrae within 10 minutes and average wet weight 2.2 g of juvenile of threadsail filefish preyed on $5.73{\pm}0.59$ polyps $g^{-1}$ of fish $h^{-1}$. Whereas adults of threadsail filefish did not prey on polyps. In feeding preference experiments to elucidate whether threadsail filefish prey on moon jellyfish in the sea, adults of threadsail filefish preyed on mostly oysters (ca. 60%) and polychaetes (ca. 80%). Medusae were consumed only 2% of total. However, juvenile of threadsail filefish preyed on ephyrae and polyps as well as mysid shrimps. Besides, polyps were consistently consumed during the experiment. Although juvenile of threadsail filefish consumed all kinds of prey, they ceased feeding at temperatures below $11^{\circ}C$, which suggests that possibility of predation on ephyrae may be very low in the sea because ephyrae are released at low temperatures below $11^{\circ}C$ from March to April. Whereas polyps are inhabitable in all seasons in Korean coastal waters, juvenile of threadsail filefish may prey on polyps in the sea. These results suggest that removing moon jellyfish at polyp stage by using juvenile of threadsail filefish is the most effective way for extermination of moon jellyfish.

미국 하버드옌칭도서관 소장 한글 방각본 소설 연구

이혜은,유춘동,Lee, Hye-Eun,Yoo, Choon-Dong 한국비블리아학회 2013 한국비블리아학회지 Vol.24 No.2

한글 방각본 소설의 상당수는 해외 기관에 소장되어 있다. 한글 방각본 소설의 종합적인 연구와 연구의 활성화를 위해서는 이 자료들에 대한 체계적인 조사와 연구가 필요하다. 이 논문은 이러한 상황에서 미국 하버드옌칭도서관(이하 옌칭도서관으로 약칭)에 소장되어 있는 한글 방각본 소설을 조사했고, 각 본의 서지(書誌)와 계통, 이본으로서의 특징을 검토하였다. 주된 목적은 그동안 이 자료들에 대한 검토가 이루어지지 못했기 때문이다. 옌칭도서관에 소장되어 있는 10종의 한글 방각본 소설은 경판본, 안성판본, 완판본으로 나뉜다. 경판본은 7종이 있는데 "구운몽", "이해룡전", "장경전", "소대성전"(2종), "춘향전", "홍길동전"이다. 안성판본은 1종으로 "양풍전"이 있으며, 완판본은 "화룡도" 2종이 존재한다. 이 본들을 살펴본 결과, 8종은 국내에서 이미 존재하는 것들이었다. 이처럼 옌칭도서관의 한글 방각본 소설이 국내에서도 쉽게 확인되는 것들인 이유는 시기적으로 1950년대에 들어서야 자료를 수집해갔기 때문이다. 이는 1890년대 조선의 개항과 동시에 영국, 러시아 연구자들이 수집했던 자료들과 차이를 보이는 점이다. 그러나 경판본 "춘향전", 효교신간(孝橋新刊) 30장본, 완판본 "화룡도" 84장본 서계서포본 2종은 현재 하버드대학 옌칭도서관에서만 확인되는 것들로 자료적 가치가 높다. 2종의 한글 방각본 소설을 통하여 경판 방각소(坊刻所) 효교(孝橋)의 특성, 완판본 서계서포 "화룡도"의 간행 양상 및 양책방본과의 관계 등을 추론해 볼 수 있었다. This study targets ten titles of Hangul banggakbon novels in the Harvard Yenching Library to examine the bibliography, system, and characteristics. Among the ten titles, gyeongpanbon Guunmong, Leehaeryongjeon, Chunhyangjeon, Janggyeongjeon, two titles of Sodaeseongjeon, Honggildongjeon, anseongpanbon Yangpungunjeon, and two titles of wanpanbon Hwaryongdo have been found in Korea, too. However, gyeongpanbon Chunhyangjeon, 30 jangbon of Hyogyosingan(孝橋新刊), and wanpanbon Hwaryongdo seogyeseopobon are the ones that can be hardly found in Korea, and the library has possessed it there so far. With the two titles of Hangul banggakbon novels, it will be needed to reexamine the aspects of publishing Hangul banggakbon novels afterwards. Hangul banggakbon novels that Harvard-Yenching Library has now are mostly the ones that can be easily found in Korea, too. It is because the data started to be collected from the 1950's. In comparison with the materials in England, Russia, or Japan in the early 1890's, there are no rare books that cannot be found in Korea. The reason for this may be found from this.

치과기공사의 전문성 인식이 자기개발 및 전문성 향상 활동에 미치는 영향

이혜은,Lee, Hye-Eun 대한치과기공학회 2021 대한치과기공학회지 Vol.43 No.3

Purpose: In this study, an attempt was made to identify the extent of dental technicians' perception of professionalism and examine to what extent the perception of professionalism impacts self-development and professionalism improvement activities. Methods: An online survey was conducted for 391 dental technicians for 20 days (i.e., from October 20 to November 10, 2020). Pearson's correlation analysis was performed to examine the correlation between the independent variable and the dependent variable, and multiple regression analysis was performed to analyze the degree of influence of independent variables on self-development and professionalism improvement activities. Results: As a result of examining the impact of dental technicians' perception of professionalism on self-development and professionalism improvement activities, it was revealed that all four subareas of the perception of professionalism, i.e., professional qualification, professional autonomy, social perception, and the sense of calling, were positively impacted. Conclusion: (1) It is necessary to compare and analyze the differences in the perception of professionalism among various dental technologist groups, prepare programs to improve them, and endeavor to ensure the growth of organizational operating system. (2) Self-development and professionalism improvement activities need to be supported so that dental technologists can immerse themselves in their duties with affections for the organization and contemplate and provide educational programs to workers.

이혜은,임중재,Lee, Hye-Eun,Im, Joong-Jae 대한치과기공학회 2019 대한치과기공학회지 Vol.41 No.4

Purpose: The purpose of this study is to provide basic data for the improvement of dental care service for patient care. Methods: The survey period was from December 10, 2018 to June 10, 2019. The subjects were 180 patients who were treated with dental implant in 20 dental hospitals and clinics in Daejeon and Gyeonggi province. A total of 145 questionnaires were analyzed except for 35 copies which were unreliable or difficult to analyze. Results: The most important care method for prolonging the life time of dental implant prosthesis was the highest rate of correct brushing (39.4%), and a majority in the subjects used oral hygiene products (91.0%). With regard to discomfort after dental implant prosthesis, food particles between the teeth showed the highest response (49.7%), and discomfort with gum infections and bleeding and reduced mastication increased significantly with age (p<0.05), whereas feeling of irritation decreased significantly with age (p<0.05). Conclusion: This study is meaningful in that it approached the perception and discomfort of prosthesis from the patients' point of view. It needs to establish the basic data to improve dental treatment service for patient care.

치과기공소 개설등록제도 개선방안에 대한 치과기공사의 인식조사: 치과의사의 치과기공소 개설등록제도를 중심으로

이혜은,류재경,이희경,김정숙,임중재,박범우,Lee, Hye-Eun,Ryu, Jae-Kyung,Lee, Hee-Kyung,Kim, Jung-Sook,Im, Joong-Jae,Park, Beom-Woo 대한치과기공학회 2021 대한치과기공학회지 Vol.43 No.1

Purpose: This study was conducted on dental technicians to examine the problems of the dental laboratory registration system and devise a plan to improve it. Methods: For data collection, an online survey was conducted on 14,015 dental technicians registered in the Korea Dental Technologist Association as of October 2020. Among the collected 405 questionnaires, 391 data were used for analysis. Results: We found that dental technicians felt that the dental laboratory opening registration system was unfair. There were problems including the problem of the verification method of job performance, not acknowledging the difference in the job field, and the lack of understanding of the structure of work cooperation between dentistry and dental laboratories. Furthermore, it was recognized that the system was improved by reflecting the change in job area according to the change of the times. Conclusion: There is an urgent need to reorganize the legal system so that the dental technicians can have their professionalism and autonomy recognized while remaining faithful to the public interest of protecting the national oral health by revising the related regulations, thereby ensuring smooth work activities.

Q방법론에 의한 치기공학과 학생의 치과기공사 직업이미지 인식 연구

이혜은,김영란,Lee, Hye-Eun,Kim, Young-Ran 대한치과기공학회 2020 대한치과기공학회지 Vol.42 No.3

Purpose: This study aimed to employ a Q-methodological approach that can understand the characteristics of each type according to the subjective structures of humans, to help understand type-specific characteristics and to provide a basis for creating the image of dental technicians among dental technology students based on the characteristics of each type. Methods: The Q-methodology was used for this study. 120 Q-statements were obtained from a qualitative survey of 120 students of the department of dental technology. To select the Q-sample, the Q-population was categorized by taking several repeated readings. The selected statements were reviewed and revised by experts and 33 Q-samples were finally selected. The data were then analyzed using the PQ method program. Results: Among 42 P specimens, 22 were classified into type 1, 9 types 2, and 11 types 3. "Type 1" recognizes the image of dental technicians positively and optimistically (Z=1.29) (Z=1.74), but it is named "self-development oriented" in the sense that steady self-development must be underpinned (Z=1.37). "Type 2" agreed strongly that they could work for a lifetime without age or gender discrimination (Z=2.09). This type was referred to as "professional-oriented" because the recognition of dental technicians is more focused on "professional." "Type 3" was tagged "pride-oriented," showing the strongest agreement that they can be proud of their job as healthcare workers (Z=1.08). Conclusion: Many studies on such an image should be carried out to determine the importance of occupational images and establish desirable status for dental technicians to continue developing.

Purpose: This study aimed to provide the basic data for improving patient satisfaction and dental services by examining the satisfaction of implant patients who have become important customers of dental treatment due to the increased demand for implants and identifying the factors affecting satisfaction. Methods: Out of 145 questionnaires, excluding 15 questionnaires that were unfaithfully responded to or difficult to analyze, 130 questionnaires were used for the analysis of the satisfaction of the dental patients with implant treatment in 19 dental hospitals and clinics in Gyeonggi-do, South Korea. Results: Implant satisfaction was as high as 3.20 (±0.56) for masticatory function satisfaction, 3.19 for psychological function satisfaction (±0.59), and 3.01 (±0.58) for social function satisfaction. Conclusion: Consistent patient care is important because an implant is not a one-shot cure but ends over a period of several months to several years. It is meaningful in that this study measured the satisfaction of implant prostheses evaluated from a patient's point of view and examined various factors and needs affecting patient satisfaction to provide the basic data for research that can contribute to improving the satisfaction of implant patients.
