구혜영,정대수,주서희,홍승권,강윤찬,Koo, Hye-Young,Jung, Dae-Soo,Ju, Seo-Hee,Hong, Seung-Kwon,Kang, Yun-Chan 한국재료학회 2006 한국재료학회지 Vol.16 No.3

The transition of europium-doped gadolinium oxide phosphor to gadolinium borate phosphor with the concentration of boron in the spray pyrolysis was investigated. The particles prepared from spray solution below 10 wt% boric acid of prepared phosphor had crystal structure of $Gd_2O_3:Eu$ phosphor, in which the crystallinity of the particles decreased with increasing the boron concentration. A single phase $GdBO_3:Eu$ phosphor particles were prepared from spray solution above 50 wt% boric acid of prepared phosphor. The phosphor particles prepared from spray solution with 20 wt% boric acid of prepared phosphor had no XRD peaks of $Gd_2O_3:Eu$ and $GdBO_3:Eu$ Therefore the phosphor particles prepared from spray solution with 20 wt% boric acid of prepared phosphor had the lowest photoluminescence intensity under ultraviolet and vacuum ultraviolet. $GdBO_3:Eu$ and $Gd_2O_3:Eu$ phosphor particles prepared from spray solutions with proper concentrations of boric acid had good photoluminescence intensity under vacuum ultraviolet. The morphology of the phosphor particles were strongly affected by the concentrations of boric acid added into spray solution.

Synalpheus jejuensis n. sp. (Crustacea: Decapoda: Alpheidae) from Korea based on morphological and molecular study

구혜영,김원 한국통합생물학회 2014 Animal cells and systems Vol.18 No.5

We describe Synalpheus jejuensis n. sp. on the basis of 17 specimens collected around Jejudo Island, Korea. The newspecies is most similar to S. tumidomanus but can be distinguished from that species by shorter scaphocerite, upturnedblunt tubercle rather than an acute spine on the superior margin of major chela, and teeth on the ventral margin of thepleura. The DNA barcoding using the mitochondrial cytochrome c oxidase subunit I (COI) gene fragment was employed inthese two species. The intraspecific sequence divergence of the COI gene of S. jejuensis n. sp. ranges between 0% and 2.1%,while that of S. tumidomanus ranges between 0.2% and 0.4%. The sequence divergence between two species is 20.1%. DNAbarcoding results provide further evidence that these two species are distinct. The discovery of S. jejuensis n. sp. isbiogeographically important because the species diversity of Synalpheus is low in temperate region.

Cell Population Changes in Transplanted Olfactory Placodes of Chimerae of Xenopus Iaevis and Xenopus borealis

구혜영,Gu, Hye-Yeong The Korean Society for Integrative Biology 1997 Korean journal of biological sciences Vol.1 No.3

When olfactory placodes are transplanted at stages 23/24 from Xenopus laevis to Xenopus borealis hosts of the same age, it is possible to distinguish the cell populations of the host and donor due to the peculiar nuclear Q bands specific to X. borealis. I have replaced the eye anlage in each of a number of X. borealis with the transplanted olfactory placode of an individual X. laevis, or vice versa. In most instances, the placode of the donor fuses with that of the host. When fusion occurs, but not when the host and donor orqans grow separately, the cells of the donor were replaced gradually and according to a characteristic pattern by cells of the host. The basal cells of the donor were the first to be replaced, followed by the more matured cells of the sensory epithelium. This cellular substitution, proceeding in an orderly fashion from bottom to upper layers of the epithelium, depends on the fusion of the two organs. This observation suggests intercellular contacts in the mitotic zone of the two organs favor the host's cells over those of the donor.

Investigation of Clinical Manifestations in Korean Colorectal Cancer Patients

구혜영,박규주,오재환,강성범,오승택,이우용 대한대장항문학회 2013 Annals of Coloproctolgy Vol.29 No.4

Purpose: Early diagnostic work-up in patients with clinical symptoms of colorectal cancer (CRC) is important to achieve good treatment results. In this study, we investigated clinical symptoms when a diagnosis of CRC was made in patients who had a surgical resection, especially focusing on the relevance of constipation to CRC. Methods: The clinical symptoms of 17,415 CRC patients who had curative surgery from January 2010 to December 2012 were collected from 24 training hospitals of surgery. Results: The number of symptomatic patients before the diagnosis of CRC was 11,085 (63.7%). Hematochezia or melena, abdominal pain, anemia, and constipation were more often found in female than male patients while bowel habit change was more common in male patients. Considering age, bowel habit change and hematochezia or melena were more common in patients younger than 60. Anemia and constipation, however, were more common in patients older than 60. According to the group classification based on age, patients older than 60 had experienced more constipation (P = 0.049). Moreover, patients with constipation tended to have a more advanced disease status (P < 0.001). Conclusion: In patients who had surgery due to CRC, bleeding, abdominal pain, bowel habit change and constipation were the most frequent symptoms before diagnosis. Although whether or not constipation is a cause of CRC is unclear, it is one of the important clinical symptoms that presents in patients with CRC, and patients with a symptom of constipation tend to present with a more advanced CRC stage.

자원봉사자의 이중관계 인식과 경험에 관한 연구

구혜영,장연진 한국사회복지교육협의회 2012 한국사회복지교육 Vol.17 No.-

This study has surveyed 145 volunteers to recognize how much they perceive and how many they have experienced dual relationships in serving their clients at social welfare field. Focused on sexual, bartering and private relationships, respondents tend to have a quite lower level of ethical perception about dual relationships while they little experienced of them. It appeared volunteers who have property of women, married, older generation have strict attitudes about dual relationships. From these results, it suggested that the administrative supervision system should be established to educate volunteers at social welfare field about ethical principles in relationship with clients, while volunteering organizations should provide a regular ethical-based training course and present a conduct guideline on dual relationships preventing volunteers' non-ethical implementation. 본 연구에서는 사회복지 현장에서 봉사자들이 클라이언트와의 이중관계에 대해 어떻게 인식하고 있으며, 이러한 이중관계의 상황을 얼마나 경험하였는지를 알아보기 위해 서울 지역 자원봉사자 200명을 대상으로 성적, 대가성, 개인적인 이중관계에 대한 인식과 경험을 조사하였다. 회수된 145명의 설문지에 대해 빈도분석 및 집단간 차이 분석을 실시한 결과, 첫째, 인식 면에서는 성적, 대가성 관계에 대해서는 비윤리적이라 인식하는 경향이 나타났으나, 개인적 관계에 대해서는 허용적인 태도를 보였다. 반면, 경험 면에서는 세 영역에 대해서 모두 경험률이 낮은 것으로 나타났다. 둘째, 인식과 경험 간에는 유의미한 차이를 보였는데, 세 영역 모두 경험보다는 인식 면에서 더 허용적임을 알 수 있었다. 그러나 각 차원의 인식과 경험 간의 상관관계가 높아, 각 상황에 대해 허용적으로 인식할수록 경험할 확률도 높아진다는 것을 알 수 있다. 셋째, 인구학적 요인에 따른 차이에서 경험보다 인식 면에서 의미있는 차이를 보였다. 즉, 남성, 비기혼자, 젊은 연령층(20-30대), 짧은 봉사기간(1년 미만)의 특성을 가진 자원봉사자들이 여성이나, 기혼자, 장노년층, 장기활동 봉사자들보다 이중관계에 대해 더 허용적이었다. 이러한 결과를 통해서 볼 때, 사회복지 현장의 자원봉사자에게는 클라이언트와의 이중관계에 대해 인식할 수 있도록 지속적인 윤리교육과 사례지도가 제공되어야 하며, 자원봉사기관에서는 이중관계를 다루는 교육과 훈련의 기회를 제공하고 비윤리적 실천이 발생하지 않도록 지도하는 시스템을 구축해야 할 것이다.
